摘要：
A method of producing a fastening device, and a fastening device, is provided. The method comprises the steps of forming a body elongating along a first axis by iteratively stacking layers, wherein the body comprises an at least partially open cavity elongating along the first axis. The method further comprises the step of forming a first and second chambers in the cavity, and forming an element, of which element a first portion projects into the first chamber and of which element a third portion projects from the cavity of the body in the first plane. The element is rotatably arranged, such that upon rotation of the element, the third portion of the element is configured to be releasably wedged within the chamber.

The patent text describes a technology called 3D printing that can create three-dimensional objects using a computer model. This technology is becoming more popular because it allows for rapid prototyping without the need for assembly or molding techniques. In this case, the text discusses the use of a fastening device for mounting lighting arrangements on a wall or ceiling. The technical problem highlighted in the text is the high cost and complexity of conventional methods for producing lighting arrangements, which may require multiple parts. The 3D printing technology offers an alternative solution to this problem.
技术功效语段：
The present invention provides a fastening device for a lighting device. The device has a hinged element that can be tilted within the fastening device, allowing for adjustable tilting of the lighting device. The hinged element is securely locked in place within the fastening device. The invention also includes a coupling arrangement and a housing for the lighting device, which can be conveniently printed using 3D printing technology. The technical effects of this invention are improved flexibility and customization for lighting devices, as well as simplified and efficient installation.
权利要求：
1. A fastening device (110), comprising a body (150) elongating along a first axis perpendicular to a first plane, wherein the body comprises an at least partially open cavity (160) elongating along the first axis, a first chamber (170) and a second chamber (180) arranged in the cavity and adjacent to each other in the first plane, and an element (200) arranged in the cavity and elongating in the first plane, wherein the element (200) comprises a first portion (210) that projects into the first chamber (170), a second portion (230) that is arranged in the second chamber (180), and a third portion (240) that projects from the cavity (160) of the body (150), wherein the element (200) further is rotatably arranged around its second portion (230) in the second chamber (180), such that the second portion (230) serves as a fulcrum for the element (200), wherein at least one dimension of the third portion (240) of the element (200) is larger than a corresponding dimension of the first chamber (170), and wherein at least one of the third portion (240) of the element (200) and the first chamber (170) is resilient in the at least one dimension, such that upon rotation of the element (200) around the second portion (230), the third portion (240) of the element (200) is configured to be releasably wedged within the first chamber (170).
2. The fastening device of claim 1, wherein the third portion comprises at least one resilient part (300, 500) extending in the first plane such that upon rotation of the element around the partition means, the at least one part is configured to come into abutting contact with at least a portion of the first chamber wall, whereby the at least one part is biased by the force of the at least one portion of the first chamber wall.
3. The fastening device of claim 2, wherein the at least one resilient part is configured to come into abutting contact with at least a portion of at least one side of the cavity at least partially defining the first chamber wall.
4. The fastening device of claim 2 or 3, wherein the at least one resilient part (300) is configured to come into abutting contact with at least a portion of the base (310) of the cavity of the body at least partially defining the first chamber wall.
5. The fastening device of any one of claims 2-4, wherein the at least one resilient part comprises at least one spring element (300).
6. The fastening device of any one of the preceding claims, wherein at least one of the third portion of the element and a portion of the first chamber wall comprises a friction surface.
7. The fastening device of any one of the preceding claims, wherein the element further is rotatably arranged around the first axis of the second portion.
8. The fastening device of any one of the preceding claims, wherein the first portion of the element comprises a coupling arrangement for coupling the first portion to a lighting device.
9. A lighting arrangement (600), comprising a fastening device of any one of the preceding claims, and a lighting device (610) comprising at least one light source, wherein the lighting device is coupled to the first portion of the fastening device.
10. A method (700) of producing a fastening device by a 3D-printing process, in which layers of printing material deposited in a first plane are iteratively stacked along a first axis perpendicular to the first plane, the method comprising the steps of: forming (701) a body elongating along the first axis by iteratively stacking layers in the first plane, wherein the body comprises an at least partially open cavity elongating along the first axis, forming (702) a first chamber and a second chamber in the cavity, wherein the first and second chambers are adjacent to each other in the first plane, forming (703) an element, wherein element comprises a first portion that projects into the first chamber, a second portion that is arranged in the second chamber, and a third portion that projects from the cavity of the body in the first plane, wherein the element further is rotatably arranged around its second portion in the second chamber, such that the second portion serves as a fulcrum for the element, wherein at least one dimension in the first plane of the third portion of the element is larger than a corresponding dimension of the first chamber, and wherein at least one of the third portion of the element and the first chamber is resilient in the at least one dimension, such that upon rotation of the element around the second portion, the third portion of the element is configured to be releasably wedged within the first chamber.
11. The method of claim 10, further comprising the step of forming (704), on the first portion of the element, a coupling arrangement for coupling the first portion to a lighting device.
