技术问题语段:
The technical problem addressed in this patent is to provide a method for making a padding for cycling pants that is comfortable, specific, and can withstand the stresses of cycling without losing its elasticity or causing skin irritations. The method should also be cost-effective and environmentally sustainable by eliminating the use of adhesives and reducing the production of scraps or waste. Additionally, the method should provide paddings that are high-breathability, have rapid drying times, and contain encumbrances and volumes for transport.
技术功效语段:
The present invention provides a method for making a padding, particularly for cycling pants, that overcomes the technical problem of "hardening of the edges" which occurs during the manufacturing process. The method uses 3D printing to create a structure composed of individual open cells that are mutually connected and arranged mutually opposite and side by side. This results in a padding that is comfortable, has high elasticity, is not affected by heat or adhesives, and is easy to manufacture and transport. The technical effects of this method include improved protection, comfort, and durability of the cycling pad.

CLAIMS
1. A method for providing a padding (1), which is characterized in that it uses 3D printing by depositing a filament (2) according to a microarchitecture that entails the definition of superimposed matrices that are adapted to define a structure composed of individual open cells (6), which are mutually connected and arranged mutually opposite and side by side, each one having a shape in plan view with a variable diameter which is obtained by way of superimposing elements that are substantially shaped like a truncated pyramid or like a truncated cone with a polygonal base.
2. The method according to claim 1, characterized in that said microarchitecture entails the definition of various matrices which, as they are formed, are mutually superimposed and adapted to define a structure (5) which is composed of said individual open cells (6), which are mutually connected and arranged mutually opposite and side by side, each one of said open cells (6) having, in plan view, a diameter that varies as each one of said cells (6) extends upward.
3. The method according to claims 1 and 2, characterized in that said microarchitecture defines cells (6) which are obtained by depositing in sequence layers of filament (2) which have a given geometry which, in the succession of layers, has in plan view a slightly larger dimension until a point or plane (7) of maximum transverse dimension is reached.
4. The method according to claims 1 and 3, characterized in that starting from said point or plane (7) the dimensions in plan view of the subsequent layers tend to decrease until a point (8) of minimum transverse dimension is reached, the dimension in plan view of the subsequent layers returning to increase until a new point or plane (7) of maximum transverse dimension is reached.
5. The method according to claims 1 and 4, characterized in that the height of each individual open cell (6) between said points (7, 8) is identical.
6. The method according to claims 1 and 4, characterized in that said microarchitecture creates a plurality of open cells (6) which are mutually superimposed and in which one cell adjacent to another cell is offset so that said point or plane (8) of minimum dimension in plan view of the adjacent row of open cells (6b) corresponds to said point or plane (7) of maximum dimension in plan view of a row of open cells (6a).
7. The method according to one or more of the preceding claims, characterized in that with said microarchitecture the superimposition is obtained of elements or open cells (6) which are substantially shaped like a truncated pyramid with an octagonal base, said layers being deposited by generating matrices which, if one performs a transverse cross-section on the resulting product, show a sequence of elements which have, in plan view, a substantially square and octagonal shape and the sides of which are shared with those of the adjacent cells.
8. The method according to one or more of the preceding claims, characterized in that with said microarchitecture the superimposition is obtained of elements or open cells (6) which are substantially shaped like a truncated cone with a polygonal or circular base, said layers being deposited by generating matrices which, if one performs a transverse cross-section on the resulting product, show a sequence of elements which have, in plan view, a substantially circular shape with mutually tangent sides so as to generate individual open cells (6), each of which has a shape in space which can be likened substantially to the shape of a cask, having zones that are more or less free from material between adjacent cells.
9. A padding (1) obtained with said method as in one or more of the preceding claims, characterized in that it has a flat outer perimetric first zone (9) with a thickness of said cells (6) that tends toward zero, followed by a second zone (10) with a thickness of said cells (6) that is uniform and of higher value, said second zone (10) being substantially heart-shaped, the perimetric edge (10a) of which being blended with a substantially straight
branch (10b) which is arranged along the median axis of said padding (1).
10. The padding according to claim 9, characterized in that a third zone (11) is adjacent to said second zone and is V-shaped in plan view so as to define a pair of external wings (12a, 12b) and a pair of internal wings (13a, 13b) which are arranged substantially along the median axis of said padding (1), with a thickness of said cells (6) that increases from the perimeter toward the center in said pair of external wings (12a, 12b) and a thickness that decreases from the center toward the perimeter in said pair of internal wings (13a, 13b), the point of maximum elevation being the same for said pair of external wings (12a, 12b) and for said pair of internal wings (13a, 13b).
11. The padding according to claims 9 and 10, characterized in that a fourth zone (14) is adjacent to said third zone (11) and surrounds said third zone (11) with a thickness of said cells (6) that is greater than that in said third zone (11), within said fourth zone (14) there being two fifth zones (15a, 15b), which are substantially mirror- symmetrical with respect to the median axis of said padding (1), with a thickness of said cells (6) that is different from that of said adjacent fourth zone (14) and said adjacent pair of internal wings (13a, 13b) of said third zone (11).
