[0062]Referring to FIG. 1, there is illustrated a kit 100 for interconnecting and hanging pieces of material 102, according to an example embodiment. The example kit 100 depicted in FIG. 1 includes multiple pieces of the material 102, a leveling tool 104, multiple clips 106 including inner clips 106(1), corner clips 106(2)(A)-(D), edge clips 106(3), and/or locking clips 106(4), multiple hanging elements 108 including top hanging elements 108(1) and/or bottom hanging elements 108(2), command strips 110, a ruler 112, and/or a repair tool 114. It is to be appreciated that the kit 100 may exclude some of these components, in some examples, and/or the kit 100 may include additional components, in some examples. For instance, the kit 100 may include an instruction manual (not shown) that includes assembly instructions for interconnecting and hanging the pieces of material 102 and/or instructions for downloading a mobile application and/or navigating a browser to a uniform resource locator (URL) to retrieve such assembly instructions.
[0063]FIG. 1 depicts a single piece of material 102. It is to be appreciated, however, that the kit 100 may include any number of pieces of material 102, such as a few pieces of material 102, tens of pieces of material 102, hundreds of pieces of material 102, etc., which a user may interconnect and hang on a structure, such as a wall. Alternate terms such as “media,”“decoration,”“wall decoration,”“photographs,”“photos,”“sheets,”“tiles,”“cards,” or “art elements” may be used interchangeably herein to refer to the pieces of material 102 in FIG. 1. The pieces of material 102 may be made of any suitable material, combination of materials, or composite materials. For example, the pieces of material 102 may be made of card stock. In some examples, the card stock may have a portion of a photograph or another work of art (e.g., a drawing, painting, sketch, etc.) printed thereon. For example, a user may submit a photograph to a service provider who prints the photograph onto a large sheet of card stock, cuts the large sheet of card stock into multiple pieces of material 102, and then packages the pieces of material 102 in the kit 100. Such a kit 100 may then be shipped to the user who submitted the photograph, or to a different user as a gift. In other examples, the card stock included in the kit 100 may be blank, and the user may print, paint, draw, or sketch any suitable content on the card stock to create a work of art by interconnecting and hanging the pieces of material 102 on a structure. Although card stock is one example type of material that may be used for the pieces of material 102, the pieces of material 102 may be made of any other suitable type of material including, without limitation, sheet metal, plastic, cardboard, paper, wood, bamboo, or the like. In some examples, the pieces of material 102 are made of a relatively flexible, lightweight material that is relatively easy for a user to interconnect using the clips 106 described herein and/or to hang on a structure using the hanging elements 108 and/or the other components of the kit 100.
[0064]The individual pieces of material 102 may have any suitable shape. FIG. 1 depicts a square-shaped piece of material 102 that is planar and relatively thin (e.g., a square sheet of material). It is to be appreciated, however, that an individual piece of material 102 is not limited to a square-shaped piece of material 102, as the piece of material 102 may have any suitable shape including, without limitation, a circular shape, an oval shape, a triangular shape, a rectangular shape, a pentagonal shape, a hexagonal shape, an octagonal shape, or any suitable polygonal shape. Furthermore, although FIG. 1 depicts a flat, planar piece of material 102, it is to be appreciated that an individual piece of material 102 may be curved. In addition, although FIG. 1 depicts a piece of material 102 with sharp corners and straight edges, the piece of material 102 can have rounded corners, irregular edges, and/or other features cut into the material to create any suitable design aesthetic.
[0065]The individual pieces of material 102 may be of any suitable size. Taking the square-shaped piece of material 102 depicted in FIG. 1 as an example, the piece of material 102 may have width and length dimensions of 3×5 inches, 4×6 inches, 5×7 inches, 8×8 inches, 8×10 inches, 8.5×11 inches, 9×16 inches, 12×18 inches, 18×24 inches, or 24×36 inches. These are merely example sizes and it is to be appreciated that an individual piece of material 102 can be of a smaller, larger, and/or intermediate size to those listed herein. Furthermore, the pieces of material 102 included in the kit 100 may be of uniform size or variable size. For example, the kit 100 may include multiple pieces of material 102, each of the same size. Alternatively, the kit 100 may include one or more first pieces of material 102 of a first size, one or more second pieces of material 102 of a second size different (e.g., larger or smaller) than the first size, and so on. In this way, a variety of types of decorations can be created with uniform- or variable-sized pieces of material 102.
[0066]The individual pieces of material 102 may have one or more holes 116 defined therein. The hole(s) 116 defined in a piece of material 102 may be used for coupling the piece of material 102 to one or more of the clips 106. The example of FIG. 1 depicts a square-shaped piece of material 102 having four holes 116 defined therein, one hole 116 in each corner. In this example, each hole 116 can be used to couple the piece of material 102 to a respective clip 106, which means that four different clips 106 can be coupled to the individual piece of material 102 shown in FIG. 1, one clip 106 at each corner of the piece of material 102. In some examples, instead of a hole(s) 116, the piece of material 102 may include one or more perforations to make the hole(s) 116. For example, the piece of material 102 shown in FIG. 1 may have four circles of perforations, one in each corner that allows a circular section in each corner to be removed by a user to create the holes 116.
[0067]The leveling tool 104 may be used with the ruler 112 in order to mount the top hanging elements 108(1) to a structure, such as a wall, with an adhesive, as will be described in more detail below. The leveling tool 104 may be a bubble level, a laser level, or any other suitable type of leveling tool 104. The leveling tool 104 may include features that allow the leveling tool 104 to rest on, and slide along, a top edge of the ruler 112.
[0068]The clips 106 are configured to be coupled to the pieces of material 102. Alternate terms such as “connector,”“joining element,”“joint element,” or “connecting element” may be used interchangeably herein to refer to the clips 106 in FIG. 1. Some of the clips 106 are configured to be coupled to a hanging element 108 or to other clips 106. For example, the individual corner clips 106(2)(A)-(D) and/or the edge clips 106(3) may include a straight groove that is configured to slidingly engage with a straight rail on one or more of the hanging elements 108. This allows a user to slide the clips 106(2)(A)-(D), 106(3) back and forth along the straight rails of the hanging elements 108. As another example, the individual locking clips 106(4) may include a straight groove that is configured to slidingly engage with the retaining projections of certain clips 106, such as the inner clips 106(1), as will be described in more detail below. FIG. 1 depicts a single inner clip 106(1), a single edge clip 106(3), and a single locking clip 106(4). It is to be appreciated, however, that the kit 100 may include any number of inner clips 106(1), edge clips 106(3), and/or locking clips 106(4), such as a few clips 106, tens of clips 106, hundreds of clips 106, etc. Furthermore, although four corner clips 106(2)(A), 106(2)(B), 106(2)(C), and 106(2)(D) may be sufficient for hanging a rectangular-shaped decoration on a structure, such as a wall, the kit 100 may include fewer corner clips 106(2) or additional corner clips 106(2), such as extra clips 106 to ensure that a user has more than enough clips 106.
[0069]The hanging elements 108 are configured to slidingly engage with certain ones of the clips 106 (e.g., the corner clips 106(2)(A)-(D) and/or the edge clips 106(3)). The hanging elements 108 are also configured to be mounted to a structure, such as wall, with an adhesive. For example, a command strip 110 included in the kit 100 may be adhered to a planar back surface of a hanging element 108 so that the command strip 110 can be used to mount the hanging element 108 to a structure, such as a wall, by adhering the command strip 110 to the structure. FIG. 1 depicts a single top hanging element 108(1) and a single bottom hanging element 108(2). It is to be appreciated, however, that the kit 100 may include any number of hanging elements 108(1), such as a few hanging elements 108, tens of hanging elements 108, hundreds of hanging elements 108, etc.
[0070]The clips 106 and/or the hanging elements 108 may be made of any suitable material, combination of materials, or composite materials. For example, the clips 106 and/or the hanging elements 108 can be made of a plastic (e.g., thermoplastic) material (e.g., acrylonitrile butadiene styrene (ABS) plastic) or a polymer material to produce components that are relatively rigid and also lightweight, which helps to minimize the overall weight of a decoration (e.g., the decoration 200 of FIG. 2). Alternatively, the clips 106 and/or the hanging elements 108 can be made of a metal, such as aluminum, stainless steel, titanium, copper, or any other suitable metallic material. In some examples, the clips 106 and/or the hanging elements 108 can be made of acrylic, Delrin, wood, a carbon fiber material, or any other material suitable for use in interconnecting pieces of material 102, such as card stock.
[0071]The clips 106 and/or the hanging elements 108 may be manufactured using a subtractive manufacturing process, such as a process where a block of material (e.g., plastic) is machined in order to create the shapes of the clips 106 and/or the hanging elements 108 as well as the various grooves, holes, features, and contours thereof, which are shown in the figures. Other suitable manufacturing techniques include, without limitation, injection molding, extrusion, three-dimensional (3D) printing (i.e., an additive manufacturing process), and the like.
[0072]The command strip 110 is an example of an adhesive that can be used to mount a hanging element 108 to a structure, such as a wall. In some examples, the command strip 110 includes protective liners on both sides that can be peeled away to expose adhesive sides of a double-sided command strip 110. In this example, one side of the command strip 110 can be adhered to a planar back surface of a hanging element 108, and the other side of the command strip 110 can be adhered to the structure (e.g., the wall). FIG. 1 depicts a single command strip 110. It is to be appreciated, however, that the kit 100 may include any number of command strips 110, such as a few command strips 110, tens of command strips 110, hundreds of command strips 110, etc.
[0073]The ruler 112 may be used in conjunction with the leveling tool 104 in order to mount the top hanging elements 108(1) to a structure, such as a wall, with an adhesive. In particular, markings on the ruler 112 serve as a visual aid so that the user can space the hanging elements 108(1) laterally on a structure at appropriate distances from one another. The distance, D2, between the markings on the ruler 112 (measured from the center of one marking to the center of an adjacent marking) may be based at least in part on the distance, D1, between laterally-aligned holes 116 (or perforations) of the piece of material 102. For example, the distance, D2, may be equal to or slightly greater than the distance, D1. Accordingly, the sizes of the ruler 112 and the size of the piece of material 102 is not necessarily drawn to scale in FIG. 1.
[0074]Although the clips 106 can be coupled to the pieces of material 102 in a nondestructive manner if used properly, the kit 100 may nevertheless include a repair tool 114 to repair a piece of material 102 if the piece of material 102 happens to become damaged (e.g., if the corner rips or tears). For example, a corner of a damaged piece of material 102 may be inserted into the repair tool 114 to align repair material (e.g., a replacement corner section) while attaching the repair material to the damaged piece of material 102.
[0075]FIG. 2 illustrates an example decoration 200 that can be created using the example kit 100 of FIG. 1. For purposes of illustration, the pieces of material 102 in FIG. 2 are depicted as translucent pieces of material so that the clips 106, the hanging elements 108, and the command strips 110 that would otherwise be occluded by the pieces of material 102 can be seen. The example decoration 200 of FIG. 2 is made up of six pieces of material 102(1), 102(2), 102(3), 102(4), 102(5), and 102(6), and each piece of material 102 is of the same size. As mentioned above, this is merely one example, as the pieces of material 102 may be of different sizes in other examples. For example, imagine an alternative configuration where the four pieces of material 102(1), 102(2), 102(4), and 102(5) were replaced by a single, larger piece of material 102. In this alternative configuration, the decoration 200 would utilize fewer clips 106 and hanging elements 108 to interconnect and hang the pieces of material 102. In the example of FIG. 2, the decoration 200 utilizes two inner clips 106(1), four corner clips 106(2)(A)-(D), and six edge clips 106(3) that are each coupled to at least one piece of material 102. For example, each corner clip 106(2)(A)-(D) is coupled to a single corner of a single piece of material 102, each edge clip 106(3) is coupled to two adjacent pieces of material 102 at their respective corners, and each inner clip 106(1) is coupled to four pieces of material 102 at their respective corners.
[0076]In the example of FIG. 2, the decoration 200 utilizes four top hanging elements 108(1), two bottom hanging elements 108(2), and six command strips 110. The corner clips 106(2)(A)-(D) and two of the edge clips 106(3) are slidingly engaged with corresponding hanging elements 108. The hanging elements 108 are mounted to a structure (not shown in FIG. 2). In this manner, the interconnected pieces of material 102(1)-(6) are suspended on the structure, such as a wall. As mentioned above, the pieces of material 102 may have portions of a photograph or another work of art printed thereon. Accordingly, when the pieces of material 102 are arranged in a particular arrangement, interconnected, and hung on a structure, the pieces of material 102 collectively create the decoration (e.g., the photograph, a photo collage, or the like). In some examples, the pieces of material 102 can have one or more colors of pigment or ink printed thereon, or the material itself can be of a uniform or variable color to create the decoration 200.
[0077]FIG. 3A illustrates a perspective view of an example inner clip 106(1) that may be included in the example kit 100 of FIG. 1, while FIG. 3B illustrates a front view of the example inner clip 106(1) and FIG. 3C illustrates a side view of the example inner clip 106(1). The inner clip 106(1) has a base 300, such as a planar base 300. In the example of FIG. 3A, the base 300 has four cross members 302(1), 302(2), 302(3), and 302(4) adjoined at four corners of the base 300 to form an opening 304 (e.g., a substantially square-shaped opening 304) in a middle of the base 300 bounded by the four cross members 302(1)-(4). The base 300 includes a planar front surface 306. The base 300 further includes four posts 308(1), 308(2), 308(3), and 308(4) located at the four corners of the base 300. Each post 308 extends from the planar front surface 306 of the base 300 and is configured to be inserted through a hole 116 defined in a piece of material 102. As shown in FIG. 3C, each post 308 is widest at a proximal end 310 of the post 308 where the post 308 meets the planar front surface 306 of the base 300. This maximum width, W1, of the post 308 is shown in FIG. 3C. In other words, the post 308 does not include a knob or a mushroom tip at the distal end 312 (or free end 312) of the post 308, which allows the user to couple a piece of material 102 to, and remove the piece of material 102 from, the inner clip 106(1) repeatedly without destroying the piece of material 102. In some examples, the post 308 has a uniform cross-section and/or a uniform width from the proximal end 310 to the distal end 312 of the post 308 (i.e., in the Z-direction). In the example depicted in FIG. 3C, however, the post 308 has a substantially rounded tip at the distal end 312 of the post 308.
[0078]The base 300 further includes four retaining projections 314(1), 314(2), 314(3), and 314(4) located at respective centers of the four cross members 302(1)-(4). Each retaining projection 314 extends from the planar front surface 306 of the base 300 and is configured to inhibit pieces of material 102 from sliding off of the posts 308 on the opposing sides of the retaining projection 314. For instance, as shown in FIG. 3C, a distal end 316 of each retaining projection 314 is wider than a proximal end 318 of the retaining projection 314 to create one or more notches 320 between the retaining projection 314 and the planar front surface 306 of the base 300. In other words, the width, W2, of the retaining projection 314 at the distal end 316 of the retaining projection 314 is greater than the width, W3, of the retaining projection 314 at the proximal end 318 of the retaining projection 314. It is to be appreciated that the shape of the retaining projection 314 can vary. For example, the shape of the retaining projection 314 depicted in FIG. 3C may be described as a “Y-shaped” retaining projection 314 with an angled side surface that is angled at an acute angle relative to the planar front surface 306 of the base 300. Alternatively, a “T-shaped” retaining projection 314 may have orthogonal side surfaces that are either perpendicular to, or parallel to, to the planar front surface 306 of the base 300. As another alternative, a “V-shaped” retaining projection 314 may have an angled side surface that extends from the proximal end 318 to the distal end 316 such that no portion of the opposing side surfaces of the retaining projection 314 is perpendicular to the planar front surface 306 of the base 300. In any of these examples, a notch(es) 320 may be created between the retaining projection 114 (at its sides) and the planar front surface 306 of the base 300. FIG. 3C depicts an example where the retaining projection 314 is symmetrical and, therefore, two notches 320 are created on opposing sides of the retaining projection 314 (i.e., a first notch 320 at a first side of the retaining projection 314, and a second notch 320 at a second side of the retaining projection 314 opposite the first side). When a piece of material 102 is disposed in a notch 320 and a post 308 is disposed through a hole 116 in the piece of material 102, the piece of material 102 is inhibited from sliding off of the post 308. Thus, the symmetrical retaining projection 314(4) shown in FIG. 3C is configured to inhibit two different pieces of material 102 from sliding off of their respective posts 308.
[0079]As shown in FIG. 3B, each retaining projection 314 is spaced a distance, D3, from an adjacent post 308. In other words, a post 308 may be disposed at a first location on the planar front surface 306 of the base 300, and a nearby retaining projection 314 may be disposed at a second location on the planar front surface 306 of the base 300, the second location being spaced a distance, D3, from the first location. This distance, D3, provides room for a user to slide a portion of a piece of material 102 into a notch 320 created by the retaining projection 314. In clips 106 with more than one post 308, such as the inner clip 106(1), a second post 308 may be disposed at a third location on the planar front surface 306 of the base 300, the third location being spaced the distance, D3, from the second location of the retaining projection 314. With the inner clip 106(1) in particular, each post 308 is spaced the distance, D3, from an adjacent retaining projection 314.
[0080]As shown in FIG. 3C, each post 308 is taller than each of the retaining projections 314, as measured from the planar front surface 306 of the base 300 to respective distal ends 312, 316 of the post 308 and the retaining projection 314. In other words, there is a height differential between a post 308 and a retaining projection 314 such that a height, H1, of the post 308 (as measured from the planar front surface 306 of the base 300 to the distal end 312 of the post 308) is greater than a height, H2, of the retaining projection 314 (as measured from the planar front surface 306 of the base 300 to the distal end 316 of the retaining projection 314). This height differential between H1 and H2 also inhibits the piece of material 102 from sliding off of the post 308.
[0081]The inner clip 106(1) may be of any suitable size. The overall dimensions (overall length, LO1, overall width, WO1, and overall height, Hoi) are shown in FIGS. 3B and 3C. In the example depicted in FIG. 3B, the overall length, LO1, of the inner clip 106(1) may be equal to the overall width, WO1, of the inner clip 106(1). In some examples, LO1 and WO1 may each be within a range of about 10 millimeters (mm) to 20 mm. In some examples, LO1 and WO1 may each be about 14.35 mm. In some examples, the overall height, Hoi, of the inner clip 106(1) may be within a range of about 2 mm to 8 mm. In some examples, Hoi may be about 5.05 mm. The shape of the inner clip 106(1) can vary as well. FIGS. 3A-3C depict a square-shaped inner clip 106(1), but other shapes are contemplated, such as a diamond-shaped inner clip 106(1).
[0082]With reference to FIG. 3D, there is shown an example of an inner clip 106(1)′ having two retaining projections 314(1) and 314(2) on opposite sides of the base 300 instead of four retaining projections 314. Said another way, the two retaining projections 314(1) and 314(2) of the inner clip 106(1)′ are located at respective centers of two opposing cross members 302(2) and 302(4) of the four cross members 302(1)-(4). A potential advantage of the example inner clip 106(1) shown in FIGS. 3A-3C is that rotation of the pieces of material 102 in the X-Y plane is inhibited more than with the example inner clip 106(1)′. That said, a potential advantage of the example inner clip 106(1)′ is that it may be easier for a user to couple a piece of material 102 to, and/or remove a piece of material 102 from, the inner clip 106(1)′ and/or there may be less of the inner clip 106(1)′ that is visible between the pieces of material 102 in the decoration 200.
[0083]FIG. 4A illustrates a perspective view of an example edge clip 106(3) that may be included in the example kit 100 of FIG. 1, while FIG. 4B illustrates another perspective view of the example edge clip 106(3), FIG. 4C illustrates a front view of the example edge clip 106(3), FIG. 4D illustrates a back view of the example edge clip 106(3), and FIGS. 4E, 4F, and 4G illustrate various side views of the example edge clip 106(3). The edge clip 106(3) has a base 400, such as a planar base 400. In the example of FIG. 4A, the base 400 has a cutout 404 in a middle of the base 400 with two halves of the base 400 on opposing sides of the cutout 404. The base 400 includes a planar front surface 406. The base 400 further includes two posts 408(1) and 408(2) located at opposite ends of the base 400. Each post 408 extends from the planar front surface 406 of the base 400 and is configured to be inserted through a hole 116 defined in a piece of material 102. As shown in FIGS. 4E and 4F, each post 408 is widest at a proximal end 410 of the post 408 where the post 408 meets the planar front surface 406 of the base 400. This maximum width, W4, of the post 408 is shown in FIG. 4E. In other words, the post 408 does not include a knob or a mushroom tip at the distal end 412 (or free end 412) of the post 408, which allows the user to couple a piece of material 102 to, and remove the piece of material 102 from, the edge clip 106(3) repeatedly without destroying the piece of material 102. In some examples, the post 408 has a uniform cross-section and/or a uniform width from the proximal end 410 to the distal end 412 of the post 408 (i.e., in the Z-direction). In the example depicted in FIGS. 4E and 4F, however, the post 408 has a substantially rounded tip at the distal end 412 of the post 408.
[0084]The base 400 further includes a retaining projection 414 located at the middle of the base 400 (in the X-direction). The retaining projection 414 extends from the planar front surface 406 of the base 400 and is configured to inhibit pieces of material 102 from sliding off of the posts 408 on the opposing sides of the retaining projection 414. For instance, as shown in FIGS. 4E and 4F, a distal end 416 of the retaining projection 414 is wider than a proximal end 418 of the retaining projection 414 to create one or more notches 420 between the retaining projection 414 and the planar front surface 406 of the base 400. In other words, the width, W5, of the retaining projection 414 at the distal end 416 of the retaining projection 414 is greater than the width, W6, of the retaining projection 414 at the proximal end 418 of the retaining projection 414. As described above with respect to the retaining projection 314, it is to be appreciated that the shape of the retaining projection 414 can vary (e.g., a “Y-shaped” retaining projection 414, a “T-shaped” retaining projection 414, a “V-shaped” retaining projection 414, etc.) Furthermore, FIGS. 4E and 4F depict an example where the retaining projection 414 is symmetrical and, therefore, two notches 420 are created on opposing sides of the retaining projection414 (i.e., a first notch 420 at a first side of the retaining projection 414, and a second notch 420 at a second side of the retaining projection 414 opposite the first side). When a piece of material 102 is disposed in a notch 420 and a post 408 is disposed through a hole 116 in the piece of material 102, the piece of material 102 is inhibited from sliding off of the post 408.
[0085]As shown in FIG. 4C, the retaining projection 414 is spaced a distance, D4, from an adjacent post 408. In other words, a post 408 may be disposed at a first location on the planar front surface 406 of the base 400, and the retaining projection 414 may be disposed at a second location on the planar front surface 406 of the base 400, the second location being spaced a distance, D4, from the first location. This distance, D4, provides room for a user to slide a portion of a piece of material 102 into a notch 420 created by the retaining projection 414.
[0086]As shown in FIG. 4F, each post 408 is taller than the retaining projection 414, as measured from the planar front surface 406 of the base 400 to respective distal ends 412, 416 of the post 408 and the retaining projection 414. In other words, there is a height differential between a post 408 and the retaining projection 414 such that a height, H3, of the post 408 (as measured from the planar front surface 406 of the base 400 to the distal end 412 of the post 408) is greater than a height, H4, of the retaining projection 414 (as measured from the planar front surface 406 of the base 400 to the distal end 416 of the retaining projection 414). This height differential between H3 and H4 also inhibits the piece of material 102 from sliding off of the post 408.
[0087]The edge clip 106(3) may be of any suitable size. The overall dimensions (overall length, LO2, overall width, WO2, and overall height, HO2) are shown in FIGS. 4D and 4F. In the example depicted in FIG. 4D, the overall length, LO2, of the edge clip 106(3) may be different than the overall width, WO2, of the edge clip 106(3). In some examples, WO2 may be within a range of about 10 mm to 20 mm. In some examples, WO2 may be about 14.35 mm. In some examples, LO2 may be within a range of about 3 mm to 9 mm. In some examples, LO2 may be about 6.39 mm. In some examples, the overall height, HO2, of the edge clip 106(3) may be within a range of about 2 mm to 8 mm. In some examples, HO2 may be about 5.05 mm. The shape of the edge clip 106(3) can vary as well. FIGS. 4A-4G depict a rectangular-shaped edge clip 106(3), but other shapes are contemplated.
[0088]The edge clip 106(3) may further include a planar back surface 422 opposite the planar front surface 406, and a straight groove 424 defined in the planar back surface 422. The straight groove 424 is configured to slidingly engage with a corresponding straight rail of a hanging element 108. The example of FIG. 4G depicts the straight groove 424 as having a T-shaped cross section. This allows the straight groove 424 to slidingly engage with a T-shaped straight rail of the hanging element 108. It is to be appreciated, however, that the straight groove 424 can have a cross section of a different shape, such as a dovetail-shaped (or substantially triangular-shaped) cross section, a Y-shaped cross section, or the like. These cross-sectional shapes prevent the edge clip 106(3) from sliding off of the straight rail of the hanging element 108 in the Z-direction. In other words, a user can remove the edge clip 106(3) from a hanging element 108 by sliding the edge clip 106(3) all the way off of the straight rail of the hanging element 108 in the X-direction, but a user is inhibited from removing the edge clip 106(3) from the hanging element 108 by simply pulling the edge clip 106(3) away from the hanging element 108 in the Z-direction. This is due to the cross-sectional shape of the straight groove 424 defined in the planar back surface 422 of the edge clip 106(3). In some examples, the straight groove 424 extends along the entire width (e.g., the overall width, Woz) of the edge clip 106(3), as shown in FIG. 4D.
[0089]FIGS. 5A-5T illustrate various views of the example corner clips 106(2) that may be included in the example kit 100 of FIG. 1. FIG. 5A illustrates a perspective view of an example lower-right corner clip 106(2)(B), while FIG. 5B illustrates another perspective view of the example lower-right corner clip 106(2)(B), FIG. 5C illustrates a front view of the example lower-right corner clip 106(2)(B), FIG. 5D illustrates a back view of the example lower-right corner clip 106(2)(B), and FIG. 5E illustrates a side view of the example lower-right corner clip 106(2)(B). These same views are illustrated in FIGS. 5F-5J for the upper-left corner clip 106(2)(A), FIGS. 5K-5O for the lower-left corner clip 106(2)(D), and FIGS. 5P-5T for the upper-right corner clip 106(2)(C).
[0090]Each corner clip 106(2) has a base 500, such as a planar base 500. The base 500 includes a planar front surface 506. The base 500 further includes a post 508 located at one end of the base 500. The post 508 extends from the planar front surface 506 of the base 500 and is configured to be inserted through a hole 116 defined in a piece of material 102. As shown in FIGS. 5E, 5J, 5O, and 5T, the post 508 is widest at a proximal end 510 of the post 508 where the post 508 meets the planar front surface 506 of the base 500. This maximum width, W7, of the post 508 is shown in FIGS. 5E, 5J, 5O, and 5T. In other words, like the other clips 106, the post 508 of the corner clip 106(2) does not include a knob or a mushroom tip at the distal end 512 (or free end 512) of the post 508, which allows the user to couple a piece of material 102 to, and remove the piece of material 102 from, the corner clip 106(2) repeatedly without destroying the piece of material 102. In some examples, the post 508 has a uniform cross-section and/or a uniform width from the proximal end 510 to the distal end 512 of the post 508 (i.e., in the Z-direction). In the example depicted in FIGS. 5E, 5J, 5O, and 5T, however, the post 508 has a substantially rounded tip at the distal end 512 of the post 508.
[0091]The base 500 further includes a retaining projection 514 located at the same end of the base 500 as the post 508 (in the X-direction). The retaining projection 514 extends from the planar front surfa
