Description

Technical Field

[0001] This invention relates to shoes with a means of transportation, also referred to as a transport component. The means of transportation includes a frame fixed beneath the sole and a moving mechanism fixed beneath this frame. This moving mechanism allows the person wearing the shoes to move on the ground by any means, such as by wheels, a skateboard, stilts, or any similar element that allows rolling, sliding, or bearing weight. Background Technology

[0002] This means of transport is detachable from the shoe (also known as the footwear component). Therefore, when the means of transport is separated from the shoe and carried, for example, with the user, the user can typically walk normally. When the means of transport is attached to the underside of the shoe, the user can slide or roll on the ground. This assembly, including both the shoe and the means of transport, provides the user with a variety of possibilities for movement and constitutes an advantageous sports equipment device.

[0003] Therefore, a sports equipment device is known, comprising: a footwear portion, the footwear portion including a sole on one side and a transport portion on the other side, the transport portion including a frame extending along a longitudinal axis (X) oriented from front to back and a moving mechanism fixed below the frame, and the sports equipment device further including a fixing mechanism capable of detachably fixing the footwear portion to the frame and including a front attachment mechanism and a rear attachment mechanism, the front attachment mechanism including an upper front block attached to the footwear portion and a lower front block attached to the frame and capable of being fixed to the upper front block; the rear attachment mechanism including an upper rear block attached to the footwear portion and a lower rear block attached to the frame and capable of being fixed to the upper rear block.

[0004] An example of this device is described in patent FR3019470. However, in said device, integrating the upper front block and upper rear block into the footwear portion involves several steps and is complex. Summary of the Invention

[0005] The present invention aims to remedy these shortcomings.

[0006] The present invention aims to provide a sports equipment device in which the integration of the upper front block and upper rear block into the footwear portion is simplified, while allowing easy connection and removal of the frame to and from the footwear portion.

[0007] This goal is achieved by integrating the upper forefoot block and the upper rearfoot block into the sole, and by molding at least a portion of the sole onto the upper forefoot block and the upper rearfoot block.

[0008] These arrangements simplify the integration of the upper front and upper rear panels into the footwear, as is the manufacturing process. Furthermore, the correct positioning of the upper front and upper rear panels, and the maintenance of the distance between them, are achieved by molding portions (produced through molding) onto these panels. This allows for easy connection and disconnection of the frame to / from the footwear, and ensures reliable operation over time.

[0009] For example, the footwear portion further includes a retaining element that extends in a plane when at rest and is flexible but not stretchable in this plane.

[0010] Therefore, the position of the upper front block and the upper rear block is maintained over time.

[0011] For example, retain the component directly fixed to the upper front block and the upper rear block.

[0012] Therefore, further improvements are needed to maintain the positions of the upper front block and the upper rear block over time.

[0013] For example, the upper front block includes an upper front plate, a lower front plate penetrating through a central front hole, and a front spacer located between the front plates, the front plates and the front spacer being mechanically connected together, and the upper rear block includes an upper rear plate, a lower rear plate penetrating through a central rear hole and a side rear hole, and a rear spacer located between the rear plates, the rear plates and the rear spacer being mechanically connected together.

[0014] Therefore, maintaining a constant distance between the front plates and a constant distance between the rear plates makes the front and rear attachment mechanisms more reliable.

[0015] For example, the front spacer is a single part and has a closed front wall surrounding the front hole at its center, and the rear spacer has a closed rear central wall surrounding the central rear hole and a closed rear side wall surrounding the side rear hole on its front portion.

[0016] These spacers help prevent molding material from entering the holes in the lower front and lower rear plates, which are intended to receive the lower front and lower rear blocks attached to the frame.

[0017] For example, the upper front plate has a front convexity, and the upper rear plate has a rear convexity.

[0018] Therefore, the front and rear plates and the upper rear plate are more reliably held in place during molding.

[0019] For example, the sole includes an outsole and an insole, each molded together, with the insole being overmolded onto the outsole as well as onto the upper forefoot block and the upper rearfoot block.

[0020] Therefore, the sole is manufactured solely through molding. This simplifies the manufacturing process.

[0021] For example, the outsole has a front hole surrounded by a front wall that houses the front plate therein, the front hole opening to the outer surface, and a rear hole surrounded by a rear wall that houses the rear plate therein, the rear hole opening to the outer surface.

[0022] These front and rear walls help prevent molding material from entering the holes in the front and rear panels and the lower rear panel, which are intended to receive the lower front and lower rear blocks attached to the frame.

[0023] For example, the frame includes an upper shell and a lower shell that can be mechanically fastened together in a detachable manner.

[0024] Therefore, the assembly of the frame is simplified. In addition, the maintenance and repair of the frame are easier when necessary.

[0025] The present invention also relates to a method for manufacturing a sports equipment device.

[0026] According to the present invention, the method includes the following steps:

[0027] (b) Providing an upper front block and an upper rear block, and manufacturing a sole, wherein at least a portion is molded onto the upper front block and the upper rear block in such a way that these upper blocks are integrated into the sole as part of the footwear;

[0028] (c) Provide a frame, a lower front block, and a lower rear block, with the lower block attached to the frame;

[0029] (d) The moving mechanism is fixed below the frame;

[0030] (e) The lower front block is fixed to the upper front block and the lower rear block is fixed to the upper rear block so that the footwear portion can be detachably fixed to the frame.

[0031] For example, prior to step (b), the method includes the following step (a):

[0032] (a) Outsole manufactured by molding;

[0033] Furthermore, the method ensures that in step (b), the sole comprises an outsole and an insole formed by molding, the insole being overmolded onto the outsole and onto the upper forefoot block and the upper rearfoot block. Attached Figure Description

[0051] In the following description and as illustrated in the figures, footwear component 1, sole (10, 11, 12), retaining element 13, frame 30, front attachment mechanism 50, and rear attachment mechanism 60, as well as other parts of the sports equipment, are positioned and oriented relative to an orthogonal reference system (X, Y, Z), which has a horizontal longitudinal axis X oriented from front to back, a horizontal transverse axis Y, and a vertical axis Z oriented from bottom to top. The terms “front” and “rear” are defined relative to the longitudinal axis. The terms “top,” “above,” “below,” “on top of,” “bottom,” “below,” “below,” and “below the bottom” are defined relative to the vertical axis Z.

[0052] According to the invention, at least a portion of the sole 10 is produced by molding and molded onto the upper forefoot block 50H and upper rearfoot block 60H, which are described below. For example, the remaining portion of the sole is manufactured by extrusion or lamination, then cut to give it its final shape, and assembled to the molded portion of the sole, such assembly being performed by any means (e.g., by stitching and / or gluing and / or thermal welding). Alternatively, the entire sole 10 is molded.

[0053] "Molded onto the upper front block 50H and upper rear block 60H" should be understood as meaning that the molding material surrounds at least the top and sides of the upper front block 50H and upper rear block 60H.

[0054] Advantageously, the molded portion of the sole 10 extends from the front to the rear of the sole 10 and laterally covers the entire horizontal surface of the sole 10. Because the molded material is waterproof, the footwear portion 1 is waterproof in the vertical direction, allowing the user's feet to remain dry when walking on wet surfaces.

[0055] Figure 1 The sports equipment device according to the present invention includes a footwear portion 1, the footwear portion including a sole 10. Figure 1 In some embodiments, the sole 10 is a single piece, meaning the sole is molded as a single sheet. This molding is performed, for example, by injection molding. The footwear portion 1 also includes an upper portion (not shown) attached to the top of the sole 10, which is intended to cover or wrap around the user's foot. Attachment is achieved, for example, by gluing and / or sewing onto the periphery of the upper surface of the sole 10.

[0056] Figure 2This illustration describes an embodiment where the sole 10 is divided into two parts and thus consists of an insole (upper sole) 11 and an outsole (lower sole) 12, which are molded separately. The insole 11 has a lower surface 112 and an upper surface 111. The outsole 12 has a lower surface 122 (outer surface) and an upper surface 121. The upper part (not shown) is then attached to the upper surface 111, for example, to the periphery of the upper surface 111.

[0057] Alternatively, the sole 10 may consist of three or more soles that are individually molded and then stacked or overmolded one by one.

[0058] The sports equipment also includes a transport section 2, which comprises a frame 30 extending along a longitudinal axis X oriented from front to back, and a moving mechanism 80 fixed below the frame 30, specifically for movement on the ground. The moving mechanism 80... Figure 1 and Figure 2 The middle part is schematically represented by a dashed line.

[0059] The sports equipment device further includes a fixing mechanism 40 capable of detachably fixing the footwear portion 1 to the frame 30. The fixing mechanism 40 includes a front attachment mechanism 50 and a rear attachment mechanism 60. The front attachment mechanism 50 is located at the front portion of the sports equipment device and includes an upper front block 50H located in the footwear portion 1 and a lower front block 50B located in the frame 30 and capable of being fixed to the upper front block 50H. The rear attachment mechanism 60 is located at the rear portion of the sports equipment device and includes an upper rear block 60H attached to the footwear portion 1 and a lower rear block 60B attached to the frame 30 and capable of being fixed to the upper rear block 60H. It should be noted that... Figure 1 and Figure 2 For clarity, the front attachment mechanism 50 and the rear attachment mechanism 60 are shown pulled out from the footwear section 10 and the frame 30.

[0060] The upper front block 50H and upper rear block 60H of the fixing mechanism 40 will be described first.

[0061] In embodiments where the sole 10 is a single piece, the upper forefoot block 50H and the upper rearfoot block 60H are embedded within the sole 10. However, the upper forefoot block 50H and the upper rearfoot block 60H each open to the lower surface of the sole 10 to allow them to be secured to the lower forefoot block 50B and the lower rearfoot block 60B, respectively. Therefore, molding material surrounds the top and sides of the upper forefoot block 50H and the upper rearfoot block 60H. For example, ridges of the molding material also cover the periphery of the lower surfaces of the upper forefoot block 50H and the upper rearfoot block 60H.

[0062] In embodiments where the sole 10 includes an insole 11 and an outsole 12, the upper forefoot block 50H and the upper rearfoot block 60H are integrated into the outsole 12 and the insole 11, as shown below. Figure 3 As shown, Figure 3The various parts are illustrated in an exploded perspective view before they are assembled into their correct positions. Thus, the upper front block 50H and upper rear block 60H are embedded in the outsole 12 and insole 11. However, the upper front block 50H and upper rear block 60H each open to the outer surface (lower surface) 122 of the outsole 12 to allow them to be secured to the lower front block 50B and lower rear block 60B, respectively. Therefore, molding material surrounds the top and sides of the upper front block 50H and upper rear block 60H. For example, ridges of the molding material also cover the periphery of the lower surfaces of the upper front block 50H and upper rear block 60H.

[0063] The outsole 12 and the insole 11 are each produced by molding, with the insole 11 being overmolded onto the outsole 12, the upper front block 50H, and the upper rear block 60H. For example, this molding and overmolding are performed by injection molding.

[0064] The upper front block 50H includes an upper front plate 51H, a lower front plate 52H penetrating through a central front hole 521H, and a front spacer 53H located between these front plates 51H and 52H. The front plates 51H, 52H, and the front spacer 53H extend in the horizontal planes X and Y and are mechanically connected together along the vertical axis Z. This mechanical connection is achieved, for example, by riveting, with the rivets passing through holes in each of the front plates 51H, 52H, and the front spacer 53H, such as... Figure 3 As explained in the document. For example, the front panels 51H and 52H are made of metal to provide rigidity and strength. Figure 1 and Figure 2 The upper front block 50H is described after the individual parts are assembled. The front spacer 53H has a constant thickness (along the vertical axis Z), which allows a constant distance to be maintained between the two front plates 51H and 52H.

[0065] Advantageously, the front spacer 53H is a single part and has a closed front wall 531H at its center, which surrounds the central front hole 521H after the front block 50H is assembled, as... Figure 3 As explained in the description. The front wall 531H helps prevent material from filling the central front hole 521H during the overmolding of the insole 11, where the tab 51B (see below) of the lower front block 50H will be secured. Similarly, in embodiments where the sole 10 is a single piece, the front wall 531H helps prevent material from filling the central front hole 521H during the molding of the sole 10.

[0066] Alternatively, the front spacer 53H may be divided into multiple parts. For example, the front spacer 53H may consist of several non-intersecting pipes, each pipe surrounding one of the mechanical connecting elements (e.g., rivets) of the front plates 51H and 52H. This situation is... Figure 7 and 8 The explanation is as follows.

[0067] The upper rear block 60H includes an upper rear plate 61H, a lower rear plate 62H penetrating through a central rear hole 621H and a side rear hole 622H, and a rear spacer 63H located between the rear plates 61H and 62H. The side rear hole 622H is located further forward than the central rear hole 621H. The rear plates 61H, 62H and the rear spacer 63H extend in the horizontal planes X and Y and are mechanically connected together along the vertical axis Z. This mechanical connection is achieved, for example, by riveting, with the rivets passing through holes in each of the rear plates 61H, 62H and the rear spacer 63H, such as... Figure 3 As explained in the document. For example, the back plates 61H and 62H are made of metal. Figure 1 and Figure 2 The upper rear block 60H is described after the various parts are assembled. The rear spacer 63H has a constant thickness (along the vertical axis Z), which allows a constant distance to be maintained between the two rear plates 61H and 62H.

[0068] Advantageously, the rear spacer 63H is a single part and has a closed rear center wall 631H at its center, which surrounds the central rear hole 621H after the rear block 60H is assembled, as... Figure 3 As described in the text. The rear center wall 631H helps prevent material from filling the center rear hole 621H during the overmolding of the inner bottom 11, where the hook 64B (see below) will secure the lower rear block 60H. The rear spacer also has a closed rear side wall 632H at its front portion, which surrounds the side rear hole 622H after the upper rear block 60H is assembled, as... Figure 3 As explained below, the rear sidewall 632H helps prevent material from filling the rear side hole 622H during the overmolding of the insole 11, where the tip 65B of the rear block 60B will be received (see below). Similarly, in embodiments where the sole 10 is a single piece, the rear center wall 631H and the rear sidewall 632H help prevent material from filling the center rear hole 621H and the rear side hole 622H during the molding of the sole 10.

[0069] Alternatively, the rear spacer 63H may be divided into multiple parts. For example, the rear spacer 63H may consist of several non-intersecting pipes, each pipe surrounding one of the mechanical connecting elements (e.g., rivets) of the rear plates 61H and 62H. This situation is... Figure 7 and 8 The explanation is as follows.

[0070] like Figures 2 to 4As described, after molding, the outsole 12 has a front hole 125 surrounded by a front wall 1251 and intended to accommodate a lower front plate 52H. During assembly, the upper front plate 51H rests against the front wall 1251, and the lower front plate 52H is accommodated in the front hole 125 and opens to the outer surface 122 of the outsole 12. The front wall 1251 helps prevent material from filling the central front hole 521H during the overmolding of the insole 11. Similarly, after molding, the outsole 12 has a rear hole 126 surrounded by a rear wall 1261 and intended to accommodate a lower rear plate 62H. During assembly, the upper rear plate 61H rests against the rear wall 1261, and the lower rear plate 62H is accommodated in the rear hole 126 and opens to the outer surface 122 of the outsole. The rear wall 1261 helps prevent material from filling the central rear hole 621H and the side rear hole 622H during the overmolding of the insole 11. Figure 4 This describes the upper blocks 50H and 60H that are assembled with the outer sole 12 before the inner sole 11 is overmolded.

[0071] The lower front plate 52H and the lower rear plate 62H extend to the lower surface (outer surface 122) of the sole 10, but do not extend beyond the lower surface, so as not to interfere with the user's walking when the transport part 2 is not fixed to the footwear part 1.

[0072] Advantageously, the upper front plate 51H has a front relief 511H, and the upper rear plate 61H has a rear relief 611H. These reliefs help to hold the upper blocks 50H and 60H in place on the outer sole 12 during the overmolding of the inner sole 11. For example, these reliefs are notches located on the periphery of the upper plates 51H and 61H, such as... Figures 1 to 4 As explained in the text. Similarly, in embodiments where the sole 10 is a single piece, these protrusions help to hold the upper blocks 50H and 60H in place during the molding of the sole 10.

[0073] Alternatively, the upper plates 51H and 61H have recesses or holes on their upper surfaces, in which pins are received. These pins help to hold the upper blocks 50H and 60H in place on the outsole 12 during the overmolding of the insole 11. Similarly, in embodiments where the sole 10 is a single piece, these pins help to hold the upper blocks 50H and 60H in place during the molding of the sole 10.

[0074] Figure 5 and Figure 6 This describes the lower plates 52H and 62H accommodated in holes 125 and 126 during the overmolding of the insole 11. During this overmolding, material covers and surrounds the upper front plate 51H and upper rear plate 61H, such that these plates are accommodated in the front cavity 115 and rear cavity 116 on the lower surface 112 of the insole 11. Figure 6 In the middle, the insole 11 is removed from the outsole 12 to show these cavities. Figure 5The final sole 10 is shown after the insole 11 has been molded onto the outsole 12.

[0075] The molding of the sole 10, such as the molding of the insole 11 and the overmolding of the outsole 12, is performed using a thermoplastic polymer or a thermosetting polymer.

[0076] For example, thermoplastic elastomers (“thermoplastic rubber” TR) are used as polymers in which the injection temperature is between 160°C and 210°C, the injection pressure is between 20 bar and 80 bar, and the injection duration is between 90 seconds and 120 seconds.

[0077] For example, thermoplastic polyurethane (“thermoplastic polyurethane” TPU) is used as a polymer in which the injection temperature is between 150°C and 190°C, the injection pressure is between 20 bar and 120 bar, and the injection duration is between 240 seconds and 300 seconds.

[0078] Advantageously, footwear portion 1 further includes a retaining element 13, also known as the inner sole of the assembly, which allows a substantially constant longitudinal distance (gap) to be maintained between the upper forefoot block 50H and the upper rearfoot block 60H over time. Thus, the retaining element 13 extends in a plane (the horizontal planes X and Y at rest) and is flexible but not stretchable, meaning it is subject to stress within its plane at rest. "Deformable" should be understood to mean easily deformable by hand. "Not deformable" should be understood to mean that it cannot be significantly deformed by hand.

[0079] For example, the retaining element 13 is a plastic sheet attached to the insole 11 (or sole 10) and positioned above the insole 11 (or sole 10) with reference to the vertical axis Z. The retaining element 13 is secured to the top of the insole 11 (or sole 10), for example, by gluing and / or sewing. Alternatively, the retaining element 13 is secured below the upper part (not shown) of the footwear portion 1, which is then secured to the insole 11 (or sole 10), as described above. In these cases, blocks 50H and 60H are not directly connected by the retaining element 13, but are indirectly connected by means of the insole 11 (or sole 10). The retaining element 13 helps prevent the insole 11 (or sole 10) from deforming in its plane (horizontal planes X, Y) when at rest. Figure 3 The description of retaining element 13 is as follows.

[0080] For example, retaining element 13 is a pair of plastic sheets 131 and 132 that sandwich the upper plates 51H and 61H in the middle, such as Figure 7As shown in the diagram. This pair of sheets includes an upper sheet 131 and a lower sheet 132. The lower sheet 132 has a front hole and a rear hole to allow spacers 53H and 63H to pass through, and lower plates 52H and 62H are located below the lower sheet 132. The upper sheet 131 and the lower sheet 132 are assembled by heating and pressure to embed the upper plates 51H and 61H therebetween.

[0081] Alternatively, the retaining element 13 can be a plastic or metal strip located above the upper blocks 50H and 60H, such as... Figure 8 As shown in the diagram. In all cases, retaining element 13 is directly fixed to the upper plates 51H, 61H. This is achieved, for example, by riveting. Advantageously, the rivets used for riveting each of the upper blocks 50H, 60H are used for this riveting.

[0082] Next, the lower front block 50B and lower rear block 60B of the fixing mechanism 40 will now be described.

[0083] The lower front block 50B and lower rear block 60B are integrated into the frame 30. The frame 30 is substantially planar and extends in the horizontal planes X and Y, and is non-deformable under tension and compression (meaning forces within its plane when at rest), which makes it possible to maintain a constant distance between the lower front block 50B and the lower rear block 60B. Advantageously, the frame 30 includes an upper housing 31 and a lower housing 32 that can be mechanically fixed together in a detachable manner. Therefore, the assembly of the lower front block 50B and the lower rear block 60B with the frame 30 becomes easier. Figure 9 These various parts are illustrated with an exploded perspective view before they are assembled into their correct positions.

[0084] The lower front block 50B has a base extending upward through a tab 51B, the tab having a distal end that bends forward to form a hook. The lower front block 50B can be seen in... Figure 9 For example, the lower front block 50B is a single piece, which facilitates its manufacturing.

[0085] The lower rear block 60B includes a guide 61B, a support 62B, a bracket 63B, a pair of hooks 64B, each hook having a rearward curved upper end and a convex top, a stop 65B, and a spring 66B. Figure 10 An exploded perspective view of the various parts of the lower rear block 60B before they are assembled into their correct positions is shown. The case of a pair of 64B hooks is described below. Alternatively, a single hook 64B or more than two hooks 64B may be present.

[0086] The following describes the assembly of the front block 50B and the lower rear block 60B with the frame 30.

[0087] The front block 50B is placed on the upper surface of the lower housing 32 in the front housing, such that the front block 50B is integral with the lower housing 32 in the horizontal planes X and Y. The support member 62B is placed on the upper surface of the lower housing 32 in the rear housing, such that the support member 62B is integral with the lower housing 32 in the horizontal planes X and Y. The front block 50B is oriented to guide the distal end of the forward-guiding tab 51B. This step is... Figure 11 The explanation is as follows.

[0088] Next, the upper housing 31 is placed on the lower housing 32. The base of the lower front block 50B is clamped between these housings 31 and 32, preventing the lower front block 50B from moving vertically. The upper housing 31 has a hole at the front, through which a tab 51B passes, extending above the upper surface of the upper housing 31. The periphery of the support member 62B is clamped between the housings 31 and 32, preventing the support member 62B from moving vertically. The upper housing 31 has a rear hole 316 at the rear, which allows access to the central portion of the support member 62B, particularly the two parallel side grooves 624B and the two front and rear grooves 623B, all of which pass through this central portion. These four grooves 624B and 623B extend along the longitudinal axis X. This step is in Figure 12 The explanation is as follows.

[0089] Next, the upper housing 31 and the lower housing 32 are mechanically assembled. For example, assembly is achieved by screws and nuts, with the screws passing through holes in the upper housing 31 and the lower housing 32. Figure 12 As shown in the following figures, there are two holes positioned towards the front of the frame 30 and two holes positioned towards the rear of the frame 30. For example, screws also pass through a portion of the moving mechanism 80 and are used to secure the moving mechanism 80 to the frame 30.

[0090] The stop member 65B is then inserted into the front portion of the rear hole 316 of the upper housing 31. The front portion of the rear hole 316 is shaped to match the lower portion of the stop member 65B, such that the stop member 65B remains vertical and prevents movement of the stop member 65B within the horizontal X and Y planes. The upper portion of the stop member 65B protrudes above the upper surface of the upper housing 31. Advantageously, this upper portion of the stop member 65B is directed towards the upper surface. This step is performed in... Figure 13 The explanation is as follows.

[0091] Then, the hook 64B is assembled with the bracket 63B. The bracket 63B has two slots 634B in its central portion. The hook 64B is inserted vertically into these slots from bottom to top, such that the upper portion of the hook 64B protrudes above the bracket 63B. The hook 64B has two arms 643B in its middle, which extend forward and backward and are each curved upward at their distal ends, and the central portion of the bracket 63B rests against these arms. Therefore, translational movement of the hook 64B relative to the bracket 63B in the horizontal planes X and Y is prevented (through the slots 634B and by means of the arms 643B that block the central portion of the bracket 63B), and vertical translational movement of the hook 64B upward is prevented, rather than vertical translational movement downward. The central portion of the bracket 63B extends at the front and rear by two downwardly curved tabs 632B. The hook 64B and bracket 63B, having their various parts, can be seen in... Figure 10 middle.

[0092] Then, the assembly consisting of hooks 64B and brackets 63B is placed in the rear hole 316 of the upper housing 31. This assembly is located behind the stop member 65B. The lower end of each hook 64B is inserted into a side groove 624B, allowing the hook 64B to slide longitudinally within the side groove 624B. The lower end of each tab 632B is inserted into a front and rear groove 623B, allowing these hooks 632B to slide longitudinally within the front and rear grooves 623B. This step is... Figure 14 The explanation is as follows.

[0093] Then, spring 66B is placed in the rear hole 316 of the upper housing 31. The front end of spring 66B abuts against the stop member 65B, and the rear end abuts against the front protrusion 632B of bracket 63B. Therefore, when at rest or under slight compression, spring 66B pushes bracket 63B rearward until the rear protrusion 632B of bracket 63B abuts against the rear edge of the rear hole 316. This step is... Figure 15 The explanation is as follows.

[0094] Then, the rear hole 316 is covered by a guide member 61B. The guide member 61B has two parallel grooves 614B at its central portion, which extend longitudinally and pass through the upper end of the hook 64B. Thus, the guide member 61B covers the bracket 63B and the spring 66B, preventing the bracket 63B, hook 64B, and spring 66B from vertically translating upwards along the Z-axis. The guide member 61B has a notch 615B at its front end, through which the upper portion of the stop member 65B passes. The stop member 65B has two lateral shoulders 651B in its central portion, with the lateral edges of the notch 615B abutting the lateral shoulders, preventing the stop member 65B from vertically translating upwards along the Z-axis. This step is... Figure 16 The explanation is as follows.

[0095] The guide 61B is then mechanically secured to the support 62B. This is achieved, for example, by riveting with rivets, such as... Figure 16 As shown in the diagram. Considering that the support 62B is fixed to the frame 30 and, as explained above, prevents horizontal and vertical movement relative to the frame 30, the entire lower rear block 60B is fixed to the frame 30 and prevents its vertical and horizontal movement between the lower housing 32 and the upper housing 31 of the frame 30, except for the hook 64B which can only be longitudinally translated along the axis X within the slot 614B (or more generally, at least one hook 64B if there are only one, two, three or more hooks).

[0096] The process of securing the footwear part 1 (after its assembly) to the frame 30 (after its assembly) is described below.

[0097] The front portion of the outsole 12 (or sole 10) is positioned to contact the front portion of the upper surface of the frame 30 until the distal end of the tab 51B of the lower forefoot block 50B engages in the central forefoot hole 521H of the lower forefoot plate 52H. Subsequently, the outsole 12 (or sole 10) is rearwardly translated relative to the frame 30 until the distal end of the tab 51B passes over the front edge of the central forefoot hole 521H, such that the tab 51B engages with the upper forefoot block 50H.

[0098] Then, the rear of the outsole 12 (or sole 10) is lowered vertically against the rear of the upper surface of the frame 30 until the hook 64B penetrates the central rear hole 621H of the upper rear plate 62H. Simultaneously, the tip 65B of the lower rear block 60B enters the side rear hole 622H of the upper rear plate 62H. The rear edge of the central rear hole 621H then presses against the convex top of each hook 64B, thus resisting the spring 66B from pushing them forward. The rear of the outsole 12 continues to move vertically closer to the frame 30 until the rear edge of the central rear hole 621H passes below the upper end of each hook 64B. The spring 66B then pushes the hook 64B backward, causing the rear edge of the central rear hole 621H to be clamped between the upper end of the hook 64B and the guide 61B. Thus, the hook 64B is secured to the upper rear block 60H. Therefore, the footwear portion 1 is vertically and horizontally integrated with the frame 30 via the tab 51B and the hook 64B.

[0099] The following describes a method for removing the footwear section 1 from frame 30.

[0100] Frame 30 has a straight channel 306 formed between upper housing 31 and lower housing 32, extending horizontally rearward from rear hole 316 and leading to the rear of frame 30, such as Figure 11 and 12As described herein, the lever of a tool (not shown) is inserted through channel 306 until the end of this lever pushes the rear tab 632B of bracket 63B forward, thereby compressing spring 66B. This pushes hook 64B forward, disengaging the rear edge of the central rear hole 621H from hook 64B. The rear edge of footwear portion 1 can then be lifted away from frame 30, and footwear portion 1 moves forward relative to frame 30 to separate tab 51B from central front hole 521H. Thus, footwear portion 1 is completely detached from frame 30.

[0101] Other embodiments of the invention are possible, for example, in which the entire lower rear block 60B is sandwiched between the lower housing 32 and the upper housing 31, except for at least one hook 64B, and is locked in place between the housings 31, 32 by mechanical assembly. In this case, the upper housing 31 partially covers the guide 61B. Generally, the entire lower front block 50B is sandwiched between the upper housing 31 and the lower housing 32, except for at least one tab 51B, and the entire lower rear block 60B is sandwiched between the upper housing 31 and the lower housing 32, except for at least one hook 64B.

[0102] In view of the above description, a method for manufacturing a sports equipment device according to the present invention having a footwear portion 1 and a frame 30 includes the following steps:

[0103] Provide an upper front block 50H and an upper rear block 60H, and manufacture a sole 10 as part of footwear part 1, wherein at least a portion is molded onto the upper front block and the upper rear block such that these upper blocks 50H, 60H are integrated into the sole 10 (step (b)).

[0104] The frame 30 is assembled with the lower front block 50B and the lower rear block 60B, such that the lower blocks 50B and 60B are attached to the frame 30 (step (c)).

[0105] The moving mechanism 80 is fixed below the frame 30 (step (d));

[0106] Then, the lower front block 50B is fixed to the upper front block 50H and the lower rear block 60B is fixed to the upper rear block 60H, so that the footwear part 10 is detachably fixed to the frame 30 (step (e)).

[0107] In one particular embodiment, prior to step (b), the outsole 12 is manufactured by molding (step (a)). In step (b), the insole 11 is overmolded onto the outsole 12 and onto the upper front block 50H and upper rear block 60H. The sole 10 includes the outsole 12 and the insole 11.
