- the hooks 64B have in their middle two fingers 643B which extend forwards and backwards and are each curved upwards at their distal end, and on which the central portion of the carriage 63B rests.
- the hooks 64B are thus blocked in translation in the horizontal plane (X,Y) relative to the carriage 63B (by the slots 634B, and using the ends of the fingers 643B which block the central portion of the carriage 63B), and blocked in translation vertically upwards, but not downwards.
- the central portion of the carriage 63B is extended at the front and at the rear by two legs 632B curved downwards.
- the hooks 64B and the carriage 63B with their various parts are visible in figure 10.
- each of the hooks 64B fits into one of the side slots 624B so that the 64B hooks are able to slide longitudinally in these lateral slots 624B.
- the lower end of each of the lugs 632B is inserted into one of the front and rear slots 623B such that these hooks 632B are able to slide longitudinally in these front and rear slots 623B. This step is illustrated in Figure 14.
- the spring 66B bears at its front end against the stopper 65B and at its rear end against the front leg 632B of the carriage 63B. At rest, or slightly compressed, the spring 66B therefore pushes the carriage 63B backwards until the rear leg 632B of the carriage 63B comes into abutment against the rear edge of the rear hole 316. This step is illustrated in FIG. 15 .
- the rear hole 316 is then covered by the guide 61B.
- the guide 61B has in its central portion two parallel slots 614B which extend longitudinally and through which the upper ends of the hooks 64B pass.
- the guide 61B thus covers the carriage 63B and the spring 66B such that the carriage 63B, the hooks 64B and the spring 66B are locked in vertical translation along the Z axis upwards.
- the guide 61B has at its front end a notch 615B through which the upper part of the stopper 65B passes.
- the stopper 65B has in its central portion two transverse shoulders 651B on which rest the transverse edges of the notch 615B, such that the stopper 65B is blocked in vertical translation along Z upwards. This step is illustrated in Figure 16.
- the guide 61B is then mechanically attached to the support 62B.
- this connection is effected by riveting using rivets, as shown in FIG. 16.
- the entire bottom rear block 60B is now attached to the frame 30 and is blocked horizontally and vertically between the lower shell 32 and the upper shell 31 of this frame 30, with the exception of the hooks 64B (or more generally at least one hook 64B if there is only one, two, three or more) which are only capable of translating longitudinally along the X axis in the slots 614B.
- the front of the outsole 12 (or of the sole 10) is brought into contact with the front of the upper face of the frame 30 until the distal end of the leg 51 B of the front block bottom 50B engages in the front central hole 521H of the lower front plate 52H. Then the outsole 12 (or the sole 10) is translated rearward relative to the frame 30 until the distal end of the tab 51 B passes over the front edge of the front central hole 521 H, in order to secure this leg 51B with the top front block 50H.
- the rear of the outsole 12 (or of the sole 10) is lowered vertically against the rear of the upper face of the chassis 30 until the hooks 64B enter the rear central hole 621 H of the upper rear plate 62H.
- the tip 65B of the lower rear block 60B enters the rear side hole 622H of the upper rear plate 62H.
- the rear edge of the rear central hole 621 H then presses on the convex top of each of the hooks 64B to push them forward against the spring 66B.
- the spring 66B then pushes the hooks 64B rearwards so that the rear edge of the rear central hole 621 H is sandwiched between the upper end of the hooks 64B and the guide 61 B.
- the hooks 64B are thus secured with the high rear block 60H.
- the footwear part 1 is thus secured vertically and horizontally with the frame 30 by the tab 51B and the hooks 64B.
- the frame 30 has a rectilinear duct 306 which is formed between the upper shell 31 and the lower shell 32 and which extends horizontally rearward from the rear hole 316 until it emerges at the rear of the frame 30 , as illustrated in FIGS. 11 and 12.
- a tool (not shown) is inserted until the end of this rod pushes the rear leg 632B of the carriage 63B forwards, by compressing spring 66B.
- the hooks 64B are pushed forwards, which disengages the rear edge of the rear central hole 621 H from the hooks 64B.
- the rear edge of the footwear part 1 can then be lifted to move it away from the frame 30, then the footwear part 1 is moved forward relative to the frame 30 to disengage the lug 51 B from the front central hole 521 H.
- the footwear part 1 is thus completely separated from the frame 30.
- the entire lower rear block 60B is sandwiched between the lower shell 32 and the upper shell 31 with the exception of at least one hook 64B, and is held blocked between these shells (31, 32) by the mechanical assembly of these shells.
- the upper shell 31 partially covers the guide 61B.
- the entire lower front block 50B is sandwiched between the upper shell 31 and the lower shell 32 with the exception of at least the tab 51B, and the entire bottom rear block 60B is sandwiched between the upper shell 31 and the lower shell 32 with the exception of at least the at least one hook 64B.
- the method of manufacturing a sports equipment device according to the invention with a footwear part 1 and a frame 30 comprises the steps below:
- a high front block 50H and a high rear block 60H are provided and a sole 10 is manufactured which is part of a footwear part 1, at least a part of which is molded on the high front block and the high rear block so that these high blocks (50H, 60H) are integrated into the sole 10 (step (b));
- a frame 30 is assembled with a low front block 50B and a low rear block 60B such that the low blocks (50B, 60B) are attached to the frame 30 (step
- step (d) Is fixed under the frame 30 a displacement mechanism 80 (step (d));
- step (e) the lower front block 50B is secured with the upper front block 50H and the lower rear block 60B is secured with the upper rear block 60H, so that the footwear part 10 is removably secured to the frame 30 (step (e)).
- step (b) an outsole 12 is manufactured by molding (step (a)).
- step (b) an insole 11 is overmolded on the outsole 12 and on the upper front block 50H and the upper rear block 60H.
- the sole 10 consists of the outer sole 12 and an inner sole (11).
