[0005] Patent Document 1: U.S. Patent Application Publication No. 2002 / 0101109 Summary of the Invention

[0006] The problem the invention aims to solve

[0007] However, in the conventional skin material mounting fixture described in Patent Document 1, the removal of the skin material from the cushioning material was not considered. Therefore, removing the skin material from the cushioning material requires a complex removal operation using a jig, or the use of a jig may damage parts of the skin material mounting fixture. This increases the labor and time required for operators. Furthermore, if parts of the skin material mounting fixture are damaged, the preparation of new parts incurs costs when reinstalling the skin material onto the cushioning material.

[0008] The present invention aims to provide a clamping component and a skin material installation device for easily removing skin material from cushioning material.

[0009] Solution for solving the problem

[0010] The first embodiment of the present invention provides a clip engaging member for a skin material mounting device. The clip, together with a clip, constitutes the skin material mounting device. The clip is mounted on one of a cushioning material and a skin material, and has one claw or a pair of claws facing each other. The clip engaging member comprises: a base mounted on the other of the cushioning material and the skin material; and a main body extending from the base and capable of being inserted into the clip along its extension direction. The main body comprises: a pair of side portions facing opposite sides in a thickness direction intersecting the extension direction, at least one side portion being capable of facing the claw; an engaging portion formed on at least one of the side portions, capable of engaging with the claw; and a release guide portion formed in the side portion in a range including a position adjacent to the engaging portion in a length direction intersecting both the extension direction and the thickness direction, extending to the apex of the extension direction, capable of guiding the claw in the extension direction.

[0011] In the first embodiment of the invention, the main body of the clip engaging member is inserted into the clip, and at least one engaging portion formed on one of the pair of side portions of the main body engages with the claw portion of the clip, thereby enabling the skin material to be mounted on the cushioning material.

[0012] With the clamp engaging with the clamp, moving the clamp engaging member relative to the clamp in the longitudinal direction allows the claw to move towards the release guide. Furthermore, moving the clamp engaging member relative to the clamp in the opposite direction of extension allows the claw to be guided by the release guide and pulled out of the main body from the clamp. Thus, without damaging parts or performing complicated release operations, the clamp engaging member can be released from the clamp, making it easy to remove the skin material from the cushioning material.

[0013] In a first embodiment of the invention, the release guide portion may have a surface shape extending over the range of the side portion, or it may have a stepped portion forming multiple steps in the extending direction.

[0014] Furthermore, in the first embodiment of the present invention, it is preferable that the dimension in the thickness direction of the main body portion determined by the release guide portion decreases toward the extension direction.

[0015] This structure allows for proper guidance of the claws.

[0016] In a first embodiment of the invention, it is preferred that at least one of the pair of side surfaces has a recess that opens on the side surface, and the engaging portion includes an engaging surface formed in the recess in a direction opposite to the extending direction.

[0017] In such a structure, the unexpected disengagement of the clamping member can be prevented by retracting the claw into the recess.

[0018] In a first embodiment of the invention, it is preferred that an inclined surface is formed in the recess, the inclined surface facing the opening of the recess, and extending from the bottom of the recess to the edge of the recess adjacent to the release guide portion while inclined relative to the length direction.

[0019] In this structure, when the clamping member is released from the clamp, the claw can be easily pulled out of the recess by sliding the claw relative to the inclined surface of the recess.

[0020] In a first embodiment of the invention, it is preferable that the edge of the recess protrudes in the thickness direction relative to the release guide portion adjacent to the edge.

[0021] In this structure, when the clamping member moves relative to the clamp in the longitudinal direction, a clicking sensation can be obtained when the claw moves from the edge of the recess to the release guide.

[0022] In a first embodiment of the invention, it is preferred that the main body portion further includes an engagement guide portion formed in at least one of the pair of side portions at a position closer to the top end of the engagement portion than the extension direction, and inclined relative to the extension direction, wherein the thickness dimension of the main body portion determined by the engagement guide portion decreases toward the extension direction.

[0023] In this structure, it becomes easy to insert the main body of the clamping component into the clamp.

[0024] In a first embodiment of the invention, the engaging guide portion may have an inclined surface that is inclined relative to the extending direction, or it may have a stepped portion that forms multiple steps in the extending direction.

[0025] In a first embodiment of the invention, it is preferred that the main body portion further includes a protrusion that protrudes along the thickness direction in at least one of the pair of side portions.

[0026] In this structure, it becomes easy for workers to operate the clamping components by pressing the protrusions.

[0027] In a first embodiment of the invention, it is preferred that at least one of the pair of side portions is alternately formed with one or more of the engaging portions and a plurality of the disengaging guide portions in the length direction.

[0028] In this structure, when the clamp engaging member is released from the clamp, it can also move relative to the clamp in any direction along the length. Furthermore, when multiple engaging parts exist, the engaging position of the clamp engaging member relative to the clamp can be adjusted, or the clamp engaging member can engage with multiple clamps.

[0029] In a first embodiment of the invention, it is preferred that the main body portion further includes at least one limiting protrusion that protrudes from one side of the engagement portion in the length direction in the thickness direction.

[0030] In such a structure, when the clamp engaging member is disengaged from the multiple clamps, the protrusion is restricted from contacting the claw of any one of the clamps, thereby suppressing excessive relative movement of the clamp engaging member relative to the clamps.

[0031] In a first embodiment of the invention, it is preferred that the engaging portion is composed of a plurality of protrusions that protrude from at least one of the side portions in the thickness direction and are arranged along the length direction.

[0032] In such a structure, the skin material can be easily installed even when the mounting part of the skin material in the cushioning material is bent.

[0033] The second aspect of the skin material mounting device of the present invention includes any one of the above-described clamp engaging members and the clamp, the clamp comprising: a clamp side base, which is mounted on one of the cushioning material and the skin material; a pair of legs disposed on the clamp side base and facing each other; and a claw, which is disposed on at least one of the pair of legs.

[0034] The skin material mounting device according to the second aspect of the present invention has the same effect as the clamp engaging member described above for the first aspect.

[0035] Preferably, the second embodiment of the skin material mounting device of the present invention further comprises a clip connector integrally formed with a plurality of clips arranged along the length direction, wherein at least one of the pair of side surfaces is alternately formed with one or more of the engaging portions and a plurality of the releasing guide portions in the length direction, a limiting surface facing the length direction is formed between the engaging portions and the releasing guide portions, the clip connector has clip-side limiting protrusions, the clip-side limiting protrusions protruding from the clip-side base between any two adjacent clips, and are formed in a manner that allows them to abut against the limiting surface.

[0036] In this structure, when the clamp engaging member is released from the clamp connecting body, the clamp-side limiting protrusion abuts against any of the limiting surfaces formed between the engaging part and the releasing guide part, thereby suppressing excessive relative movement of the clamp engaging member relative to the clamp connecting body.

[0037] In a second aspect of the invention, it is preferable that, when the recess is formed, a claw-side guide inclined surface is formed on the claw portion, the claw-side guide inclined surface being inclined relative to the length direction in such a way that it is opposite to the bottom of the recess and simultaneously opposite to the edge of the recess adjacent to the release guide portion.

[0038] In this structure, when the clamping member is released from the clamp, the claw can be easily pulled out of the recess by guiding the inclined surface of the claw side to slide relative to the edge of the recess.

[0039] The third aspect of the skin material mounting device of the present invention is a skin material mounting device comprising a clip and a clip engaging member, wherein the clip has: a clip-side base portion which is mounted on one of a cushioning material and a skin material; a pair of legs disposed on the clip-side base portion; and a claw portion disposed on at least one of the pair of legs; the clip engaging member comprises: an engaging member-side base portion which is mounted on the other of the cushioning material and the skin material; and a main body portion which extends from the engaging member-side base portion and is inserted between the pair of legs along the extending direction. The main body has a plurality of engaging portions arranged side by side at intervals along a length direction intersecting the extension direction, and can engage with the claw portion. The claw portion can sequentially perform a first movement from a state of engaging with any of the engaging portions and moving relative to each other in the length direction, and a second movement from a state of being positioned between any two adjacent engaging portions in the length direction and moving relative to each other in the opposite direction to the extension direction. The main body is pulled out from between the pair of legs by the second movement of the claw portion.

[0040] The third aspect of the present invention achieves the same effect as the first and second aspects described above.

[0041] In a third embodiment of the invention, it is preferred that the main body portion includes a slit cut into each other from the top end of the extending direction between the engaging portions that are adjacent to each other along the extending direction.

[0042] In this structure, the slit can function in the same way as the release guide described above. Attached Figure Description

[0072] Hereinafter, several embodiments of the present invention will be described. Furthermore, from the second embodiment onwards, for structures that are the same as those in the first embodiment, the same reference numerals as those in the first embodiment will be used, and descriptions will be omitted or simplified.

[0073] [First Embodiment]

[0074] Reference Figures 1-10 The first embodiment of the present invention will now be described.

[0075] exist Figure 1 In this embodiment, the skin material mounting device 1 is used to mount the skin material 3 onto the cushioning material 2 that constitutes a seat or the like, and includes a clip 4 for mounting onto the cushioning material 2 and a clip engaging member 5 for mounting onto the skin material 3.

[0076] The cushioning material 2 in this embodiment is a synthetic resin polyurethane foam material such as foamed polyurethane. This cushioning material 2 is... Figure 2 The shape of any part of the seat 9 shown (e.g., the seat surface 91, the back surface 92) is formed with grooves 2A extending in any direction. In this embodiment, the skin material 3 is a synthetic resin fabric sheet or the like that covering the surface of the cushioning material 2.

[0077] In addition, although Figure 1 The diagram is omitted, but in order to install the skin material 3 onto the cushioning material 2, multiple skin material installation devices 1 arranged along the groove 2A can also be used.

[0078] (Clip 4)

[0079] First, refer to Figure 1 and Figure 3 The following explanation will focus on clip 4.

[0080] The clip 4 is integrally formed from an elastic material such as synthetic resin. The clip 4 has: a base 41 (corresponding to the side base of the clip of the present invention); a pair of legs 421A, 421B disposed on the base 41; and a pair of claws 422A, 422B disposed on the pair of legs 421A, 421B.

[0081] The base 41 is formed, for example, in the form of a plate, and is fixed to the bottom part of the groove 2A formed in the cushioning material 2 by means of adhesive or the like (see reference). Figure 1 ).

[0082] Legs 421A and 421B are spaced apart and face each other, while claws 422A and 422B protrude from legs 421A and 421B in a direction that approaches each other and face each other.

[0083] (Clamping components)

[0084] Next, refer to Figure 1 , Figure 4 as well as Figure 5 The clamping component 5 will be explained.

[0085] The clip engaging member 5 includes: a base 51 (corresponding to the engaging member side base of the present invention), which is mounted on the end of the skin material 3; and a main body 52, which extends from the base 51.

[0086] In this embodiment, the base 51 may be a resin material integrally formed with the main body 52, or it may be a non-woven fabric or other tape component embedded in the main body 52. ​​The base 51 is fixed to the skin material 3 by means of sewing or the like.

[0087] The direction in which the main body portion 52 extends from the base portion 51 (the extension direction of the present invention) is designated as the Z direction (also called the +Z direction). The main body portion 52 has a thickness in the Y direction (corresponding to the thickness direction of the present invention), which is orthogonal to the Z direction, to the extent that it can be inserted between the legs 421A and 421B. In addition, the main body portion 52 has a length extending along the X direction (corresponding to the length direction of the present invention), which is orthogonal to both the Z and Y directions. The X direction corresponds to the direction along the end of the skin material 3.

[0088] The main body 52 includes: a pair of side portions 521A and 521B, which are opposite to each other in the Y direction and can be opposite to a pair of claw portions 422A and 422B; an engaging portion 53A and a releasing guide portion 541A, which are formed on the side portion 521A; and an engaging portion 53B and a releasing guide portion 541B, which are formed on the side portion 521B.

[0089] Furthermore, in this embodiment, release guide portions 541A are formed on both sides in the X direction relative to the engaging portion 53A, and release guide portions 541B are formed on both sides in the X direction relative to the engaging portion 53B.

[0090] in addition, Figure 4 The text refers to side portion 521A of a pair of side portions 521A and 521B. However, in this embodiment, the pair of side portions 521A and 521B have a shape that is symmetrical with respect to the XZ plane. Therefore, side portion 521B has a shape that is similar to... Figure 4 The side portion 521A shown has the same shape.

[0091] In this embodiment, each of the pair of side portions 521A and 521B has a recess 532A and a recess 532B that opens into the side portion 521A and the side portion 521B. The engaging portions 53A and 53B of this embodiment are formed from the recesses 532A and 532B of the side portions 521A and the side portion 521B, and are portions including the engaging surface 533, which will be discussed later.

[0092] like Figure 4 As shown, the recess 532A includes: a bottom 534 facing the Y direction (-Y direction side); an engaging surface 533 extending from the bottom 534 in the Y direction and facing the -Z direction; and two guide inclined surfaces 536 disposed across the bottom 534 in the X direction.

[0093] The bottom 534 can be opposite to the claw portion 422A in the Y direction. Furthermore, in this embodiment, the bottom 534 has an area sufficient to accommodate the claw portion 422A. For example, the X-direction dimension of the bottom 534 in this embodiment is equal to the X-direction dimensions of the claw portions 422A and 422B. Additionally, in this embodiment, the Y-direction dimension between the bottoms 534 of the recesses 532A and 532B is larger than the gap dimension between the pair of claw portions 422A and 422B.

[0094] The engaging surface 533 is configured to engage with the claw portion 422A housed in the recess 532A in the -Z direction.

[0095] The guide inclined surface 536 faces the opening of the recess 532A and extends from the bottom 534 of the recess 532A to the edge 535 of the recess 532A adjacent to the release guide portion 541A while being inclined relative to the X direction. This guide inclined surface 536 forms an arbitrary inclination angle θ relative to the bottom 534 (see reference). Figure 5 ).

[0096] Although partial illustrations are omitted, recess 532B has a structure that is substantially the same as that of recess 532A described above. That is, recess 532B has the following features: a bottom 534 facing the opposite side (+Y direction side) in the Y direction; an engaging surface 533 extending from the bottom 534 in the Y direction and facing the -Z direction; and two guide inclined surfaces 536 disposed across the bottom 534 in the X direction.

[0097] In addition, such as Figure 5As shown, the edge 535 of the recess 532A protrudes in the -Y direction relative to the release guide portion 541A adjacent to the edge 535, and the edge 535 of the recess 532B protrudes in the +Y direction relative to the release guide portion 541B adjacent to the edge 535. Thus, a step is formed between each edge 535 and the release guide portions 541A and 541B, and this step forms a limiting surface 537 facing the release guide portions 541A and 541B in the X direction.

[0098] like Figures 4-6 As shown, the release guide portion 541A is formed in the side portion 521A, extending from a position adjacent to the engaging portion 53A in the X direction to its top end in the +Z direction. Similarly, the release guide portion 541B is formed in the side portion 521B, extending from a position adjacent to the engaging portion 53B in the X direction to its top end in the +Z direction.

[0099] Furthermore, the Z-axis range of the release guide portions 541A and 541B includes a position adjacent to the engaging portions 53A and 53B in the X-direction to the top in the +Z-direction, preferably extending in the +Z-direction from a position on the -Z-direction side of the engaging surfaces 533 of the engaging portions 53A and 53B. The X-direction range of the release guide portions 541A and 541B is preferably equal to or greater than the X-direction dimensions of the claw portions 422A and 422B. Additionally, the release guide portions 541A and 541B preferably have a flat surface shape without significant unevenness. That is, the release guide portions 541A and 541B should each have a flat area in the pair of side portions 521A and 521B that does not obstruct the removal of the main body portion 52 from between the pair of claw portions 422A and 422B.

[0100] Furthermore, the release guide portions 541A and 541B are inclined relative to the Z direction, and the Y-direction dimension of the main body portion 52 defined by the release guide portions 541A and 541B decreases towards the +Z direction. Therefore, both the release guide portions 541A and 541B are conical in shape.

[0101] In addition, the main body 52 also has protrusions 551A and 551B that protrude from a pair of side portions 521A and 521B, respectively. In this embodiment, protrusion 551A protrudes in the -Y direction between the base 51 and the recess 532A, and protrusion 551B protrudes in the +Y direction between the base 51 and the recess 532B.

[0102] Furthermore, the main body 52 has engagement guide portions 552A and 552B respectively formed in a pair of side portions 521A and 521B, positioned closer to the +Z direction side (the tip side in the extending direction) than the recesses 532A and 532B. The engagement guide portions 552A and 552B form surfaces inclined relative to the Z direction, and the Y-direction dimension of the main body 52 defined by the engagement guide portions 552A and 552B decreases towards the +Z direction. Therefore, both the engagement guide portions 552A and 552B are conical in shape.

[0103] (Instructions for using skin material installation tool 1)

[0104] Next, the method of using the skin material mounting device 1 of this embodiment will be described. In the following description, the clamp engaging member 5 is installed on the skin material 3 and the clamp 4 is installed in the groove 2A of the cushioning material 2.

[0105] When engaging the clamping component 5 with the clamp 4, firstly, as... Figure 1 As shown, the operator aligns the clamping member 5 with the clamp 4 facing each other. At this time, the operator can also visually confirm the position of the engaging part 53A and engaging part 53B in the X direction by looking at the protrusion 551A (or protrusion 551B) of the clamping member 5.

[0106] Subsequently, the operator applies a +Z force to any location of the clamp engaging member 5, such as protrusions 551A and 551B, causing the clamp engaging member 5 to press against the clamp 4 (see reference). Figure 7 Therefore, the main body 52 of the clamp engaging member 5 (including the engaging portions 53A and 53B) is inserted between the pair of claw portions 422A and 422B of the clamp 4. At this time, the claw portions 422A and 422B abut against the engaging guide portions 552A and 552B, and are pushed outward in the Y direction from the engaging guide portions 552A and 552B. As a result, the legs 421A and 421B elastically deform by widening their intervals. Furthermore, if the claw portions 422A and 422B reach the recesses 532A and 532B and are housed within them, the legs 421A and 421B return to their original shape (see reference). Figure 8 In this state, claw portions 422A and 422B can abut against the respective engaging surfaces 533 of engaging portions 53A and 53B in the Z direction. Thus, the clamp engaging member 5 engages with the clamp 4, enabling the skin material 3 to be mounted on the cushioning material 2.

[0107] When releasing the clamp 4 from the clamp engaging member 5, the operator applies force to the clamp engaging member 5 in either the positive or negative X direction (e.g., the +X direction). At this time, as... Figure 9 As shown, claw portions 422A and 422B slide relative to the guide inclined surfaces 536 of their respective recesses 532A and 532B, and are pulled out of the recesses 532A and 532B (corresponding to the first movement of the present invention). Furthermore, claw portions 422A and 422B pass over the step between the edge 535 of the recesses 532A and 532B and the release guide portions 541A and 541B, providing the operator with a clicking sensation.

[0108] also, Figure 9 The relative positions of the clamp 4 and the clamp engaging member 5 are schematically shown. For the legs 421A, 421B and the claws 422A and 422B of the clamp 4, the positions before relative movement are indicated by dashed lines and the positions after relative movement are indicated by solid lines.

[0109] If the claws 422A and 422B are pulled out from the recesses 532A and 532B, the release guides 541A and 541B enter between the pair of claws 422A and 422B instead of pulling out the engaging parts 53A and 53B between the pair of claws 422A and 422B.

[0110] At this time, as Figure 10 As shown, a pair of claws 422A and 422B apply an inward elastic force F in the Y direction to the release guides 541A and 541B using the elastic force of a pair of legs 421A and 421B. Consequently, the clamp engaging member 5 moves in the -Z direction, being squeezed out from between the pair of claws 422A and 422B, and automatically disengages from the clamp 4 (corresponding to the second movement of the present invention). This allows the skin material 3 to be detached from the cushioning material 2.

[0111] (Effect)

[0112] In the skin material installation device 1 of this embodiment, as described above, by moving the clamp engaging member 5 relative to the clamp 4 in the X direction, the claw portions 422A and 422B can move from the engaging portions 53A and 53B to the release guide portions 541A and 541B. Furthermore, by moving the clamp engaging member 5 relative to the clamp 4 in the -Z direction, the claw portions 422A and 422B are guided by the release guide portions 541A and 541B, allowing the main body portion 52 to be pulled out from the clamp 4. Therefore, without damaging parts or performing complicated release operations, the clamp engaging member 5 can be released from the clamp 4, making it easy to remove the skin material 3 from the cushioning material 2. As a result, the skin material 3 in the seat can be easily washed and replaced.

[0113] In this embodiment, the release guide portion 541A and release guide portion 541B have a surface shape formed in the side portion 521A and side portion 521B that includes a range from the position adjacent to the engagement portion 53A and engagement portion 53B in the X direction to the top end in the +Z direction. Therefore, the claw portion 422A and claw portion 422B can be properly guided.

[0114] Furthermore, the Y-direction dimension of the main body 52, defined by the release guides 541A and 541B, decreases towards the +Z direction. Therefore, it is easier to pull the main body 52 of the clip engaging member 5 out from between the pair of legs 421A and 421B of the clip 4. In particular, in this embodiment, the clip 4 can be automatically disengaged using the elastic force of the pair of legs 421A and 421B.

[0115] In this embodiment, the engaging portions 53A and 53B are formed by recesses 532A and 532B, respectively, and the claw portions 422A and 422B are housed within the recesses 532A and 532B, thereby engaging with the engaging surfaces 533 of the engaging portions 53A and 53B. Therefore, it is possible to prevent the clamp engaging member 5 from unexpectedly disengaging.

[0116] Furthermore, guide inclined surfaces 536 are formed in the recesses 532A and 532B. Therefore, when the clamp engaging member 5 is released from the clamp 4, the claws 422A and 422B can be easily pulled out from the recesses 532A and 532B by sliding relative to the guide inclined surfaces 536 of the recesses 532A and 532B.

[0117] In this embodiment, the edge 535 of the recess 532A and the recess 532B protrudes in the Y direction relative to the release guide portion 541A and the release guide portion 541B adjacent to the edge 535. Therefore, a clicking sensation can be obtained when the claw portion 422A and the claw portion 422B move from the edge 535 of the recess 532A and the recess 532B to the release guide portion 541A and the release guide portion 541B.

[0118] In this embodiment, the Y-direction dimension of the main body 52, defined by the engaging guide 552A and engaging guide 552B, decreases toward the +Z direction. Therefore, it becomes easier to insert the main body 52 of the clip engaging member 5 between the pair of legs 421A and 421B of the clip 4.

[0119] In this embodiment, the main body 52 has protrusions 551A and 551B that protrude from a pair of side portions 521A and 521B, respectively. Therefore, it is easier for the operator to operate the clamp engaging member 5 by pressing the protrusions 551A and 551B. In addition, when the protrusions 551A and 551B are positioned on the -Z direction side of the recesses 532A and 532B, the position of the recesses 532A and 532B in the X direction can be easily confirmed by visually inspecting the protrusions 551A and 551B.

[0120] In this embodiment, in a pair of side portions 521A and 521B, one recess 532A and one recess 532B and two release guide portions 541A and two release guide portions 541B are alternately formed in the X direction. Therefore, when the clip engaging member 5 is released from the clip 4, the clip engaging member 5 can be moved relative to the clip 4 in any direction in the X direction.

[0121] In addition, in this embodiment, two guide inclined surfaces 536 are formed in the recesses 532A and 532B, which are arranged in the X direction across the bottom 534 of the recesses 532A and 532B. Therefore, it is easy to move the clamp engaging member 5 relative to the clamp 4 in any direction of the X direction.

[0122] In this embodiment, the X-direction dimension of the bottom 534 of each of the recesses 532A and 532B is equal to the X-direction dimension of the claws 422A and 422B. This suppresses the wobbling of the clamp engaging member 5 relative to the clamp 4 in the X-direction.

[0123] [Modifications of the first embodiment]

[0124] In the first embodiment described above, the details of the recesses 532A and 532B can be changed.

[0125] For example, by using the tilt angle θ formed between the guide tilt surface 536 and the bottom 534 (refer to...) Figure 5 The force required to release the engagement can be adjusted to any angle. Furthermore, by adjusting the X-direction dimension of at least one of the guide inclined surface 536 and the bottom 534, the relative X-direction movement of the clamp engaging member 5 required for release can be adjusted.

[0126] Furthermore, in the first embodiment described above, the X-direction dimension of the bottom 534 of each of the recesses 532A and 532B may be different from the X-direction dimension of the claws 422A and 422B.

[0127] For example, such as Figure 11As shown, the X-direction dimension W2 of claw portions 422A and 422B can also be made larger than the X-direction dimension W1 of the bottom 534 of recesses 532A and 532B. In this modified example, the posture of the clamp engaging member 5 relative to the clamp 4 in the XY plane can be finely adjusted, which can improve the flexibility of the skin material mounting device 1 in the XY plane.

[0128] Furthermore, although the illustration is omitted, the X-direction dimensions of claw portions 422A and 422B can also be made smaller than the X-direction dimension of the bottom 534. In such a variation, the X-direction position of the clamping member 5 relative to the clamp 4 can be finely adjusted.

[0129] Furthermore, in the first embodiment described above, two guide inclined surfaces 536 are formed in the recesses 532A and 532B, spaced apart from the bottom 534 in the X direction. As a variation, either of the two guide inclined surfaces 536 of the first embodiment may be formed in the recesses 532A and 532B.

[0130] For example, Figure 12 The clip engaging member 5A represents a variation of the first embodiment described above. Alternatively, it could be as follows... Figure 12 As shown, in recesses 532A and 532B, a guide inclined surface 536 is formed on one side (+X direction side) in the X direction relative to the bottom 534, but no guide inclined surface 536 is formed on the other side (-X direction side) in the X direction relative to the bottom 534, and the bottom 534 extends to the vicinity of the edge 535.

[0131] In addition, in the first embodiment described above, the guide inclined surface 536 is connected to the entire Z-direction range of the bottom 534, but it may also be connected to a partial Z-direction range of the bottom 534.

[0132] For example, Figure 13 This refers to a clamp engaging member 5B, representing another variation of the first embodiment described above. Furthermore, in... Figure 13 In the diagram, the configuration of the claw 422A is schematically represented using cross-sectional lines, and the movement path of the claw 422A when it is released is illustrated by black arrows.

[0133] exist Figure 13 In the clip engaging member 5B shown, the guide inclined surface 536 is partially connected to the -Z direction side of the bottom 534 in the Z direction range, and an extended edge 539 that is continuous with the edge 535 is formed on the +Z direction side of the guide inclined surface 536.

[0134] When the clamp engaging member 5B engages with the clamp 4, the claw portion 422A is positioned at... Figure 13The section line range is set to be locally opposite to the +Z direction side of the Z direction range of the bottom 534 of the recess 532A. In this state, the claw portion 422A interferes with the extended edge portion 539 in the X direction, thus suppressing movement in the X direction while keeping the position in the Z direction unchanged. Furthermore, although in Figure 13 The diagram is omitted, but the guide inclined surface 536 of the recess 532B is the same.

[0135] Therefore, the operator applies a force F1 in the +Z direction and a force F2 in either the X direction to the clamping component 5B, causing the clamping component 5B to... Figure 13 Slide in the direction indicated by the black arrow. As a result, the claw 422A reaches the release guide 541A via the guide inclined surface 536, and can release the clamp engaging member 5B from the clamp 4.

[0136] in addition, Figure 14 This illustrates another variation of the first embodiment described above, the clip engaging member 5C. Furthermore, in... Figure 14 In the diagram, the configuration of the claw 422A is schematically represented using cross-sectional lines, and the movement path of the claw 422A when it is released is illustrated by black arrows.

[0137] exist Figure 14 In the clip engaging member 5C shown, the guide inclined surface 536 is partially connected to the +Z direction side of the bottom 534 in the Z direction range, and an extended edge 539 that is continuous with the edge 535 is formed on the -Z direction side of the guide inclined surface 536.

[0138] When the clamp engaging member 5B engages with the clamp 4, the claw portion 422A is positioned at... Figure 14 The section line range is set to be partially opposite to the -Z direction side of the bottom 534 of the recess 532A in the Z direction range. In this state, the claw 422A interferes with the extended edge 539 in the X direction, thus suppressing movement in the X direction while keeping the position in the Z direction unchanged. Furthermore, although in Figure 14 The diagram is omitted, but the guide inclined surface 536 of the recess 532B is the same.

[0139] Therefore, the operator applies a force F3 in the -Z direction and a force F2 in either the X direction to the clamping component 5C, causing the clamping component 5C to... Figure 14 Slide in the direction indicated by the black arrow. As a result, the claw 422A reaches the release guide 541A via the guide inclined surface 536, and can release the clamp engaging member 5C from the clamp 4.

[0140] In the above Figure 13 , Figure 14In the modified example shown, the unexpected release of the engagement between the clip engaging member 5B, the clip engaging member 5C and the clip 4 can be prevented. Furthermore, a guide inclined surface such as a guide claw portion 422A (or claw portion 422B) facing the guide inclined surface 536 can also be formed on the extended edge 539.

[0141] In the first embodiment described above, a pair of protrusions 551A and 551B are provided. However, either one of the pair of protrusions 551A and 551B may be provided, while the other may be omitted. Alternatively, a pair of protrusions 551A and 551B may not be provided.

[0142] In addition, in the first embodiment described above, the protrusions 551A and 551B are arranged to protrude from between the base 51 and the recesses 532A and 532B, but they may also be arranged to protrude from between the base 51 and the release guides 541A and 541B.

[0143] In the first embodiment described above, the main body 52 has release guide portions 541A disposed on both sides in the X direction relative to the engaging portion 53A. However, it is also possible that the release guide portion 541A is formed on one side in the X direction relative to the engaging portion 53A, and not formed on the other side in the X direction. The release guide portion 541B is the same as the release guide portion 541A.

[0144] Furthermore, in the first embodiment described above, the release guide portions 541A and 541B are not limited to having a conical shape. For example, the thickness of the main body portion 52 between the release guide portions 541A and 541B is sufficient to allow it to be inserted between a pair of claw portions 422A and 422B.

[0145] In the first embodiment described above, the following operation was described: when the clamp 4 is engaged with the clamp engaging member 5, the clamp engaging member 5 is moved such that the claws 422A and 422B reach the engaging parts 53A and 53B via the engaging guides 552A and 552B. However, the present invention is not limited to performing such an operation.

[0146] For example, the following operation can also be performed: apply forces in the Z direction and the X direction to the clamp engaging member 5 in sequence, so that the claws 422A and 422B reach the engaging parts 53A and 53B via the release guides 541A and 541B.

[0147] Alternatively, instead of moving the clamp engaging member 5, the cushioning material 2 on which the clamp 4 is located can be moved.

[0148] [Second Implementation]

[0149] Next, refer to Figure 15 and Figure 16 The second embodiment of the skin material mounting device 1A of the present invention will be described. The skin material mounting device 1A of this embodiment includes: a clip connector 40, which integrally forms a plurality of clips 4; and a clip engaging member 5D, which includes a plurality of engaging portions 53A, 53B.

[0150] In the clip connector 40, a plurality of clips 4 are arranged at intervals in the X direction. In addition, there is a single base 41 for each clip 4 among the plurality of clips 4.

[0151] The clamp engaging member 5D has a base 51 and a main body 52D extending from the base 51 in the Z direction. The main body 52D has a pair of side parts 521A and 521B facing opposite sides in the Y direction.

[0152] In this embodiment, multiple engaging portions 53A and multiple releasing guide portions 541A are alternately formed in the X direction on the side portion 521A, and multiple engaging portions 53B and multiple releasing guide portions 541B are alternately formed in the X direction on the side portion 521B. The structures of each of the engaging portions 53A, engaging portions 53B, and releasing guide portions 541A, releasing guide portions 541B are the same as those in the first embodiment described above.

[0153] Furthermore, the number of clips 4 in the clip connector 40 and the number of engaging portions 53A and 53B in the clip engaging member 5D are not limited to the numbers shown in the figure. Also, it is not limited to the number of clips 4 in the clip connector 40 and the number of engaging portions 53A and 53B in the clip engaging member 5D being the same.

[0154] Furthermore, in the clip engaging member 5D, engaging portions 53A and 53B arranged in a face-to-back relationship are paired, and these paired engaging portions 53A and 53B can engage with corresponding clips 4. The spacing between the plurality of clips 4 in the clip connector 40 is preferably equal to or a multiple of the spacing between the plurality of paired engaging portions 53A and 53B in the clip engaging member 5D.

[0155] In this embodiment, the engagement and disengagement between the clip connector 40 and the clip engaging member 5D, that is, the engagement and disengagement between the corresponding clips 4 and engaging portions 53A and 53B, can be performed by the same operation as in the first embodiment.

[0156] For example, when releasing the clamp connector 40 from the clamp engaging member 5, the operator applies force to the clamp engaging member 5 in either the positive or negative X direction (e.g., the +X direction). However, assuming the force applied by the operator is excessive, such as... Figure 16 As shown, the sliding amount of the clamp engaging member 5D is sometimes greater than required. In such cases, the claw portions 422A and 422B approach other engaging portions 53A and 53B located next to the engaged engaging portions 53A and 53B, and abut against the limiting surface 537 of these other engaging portions 53A and 53B in the X direction, thereby stopping the excessive sliding of the clamp engaging member 5D.

[0157] also, Figure 16 The relative positions of any clip 4 with respect to the clip engaging member 5D are schematically shown. For the legs 421A, 421B and the claws 422A, 422B of the clip 4, the positions before relative movement are indicated by dashed lines and the positions after relative movement are indicated by solid lines.

[0158] The skin material mounting device 1A according to the above embodiment achieves the same effect as the first embodiment described above. Furthermore, the skin material mounting device 1A according to this embodiment can suppress excessive sliding of the clamp engaging member 5D and can prevent the claw portions 422A and 422B from engaging with the other engaging portions 53A and 53B.

[0159] [Modifications of the second embodiment]

[0160] Alternatively, the clip connector 40 or clip engaging member 5D of the second embodiment described above may also have a convex structure for suppressing excessive sliding.

[0161] For example, Figure 17 The clip connector 40 represents a variation of the second embodiment described above. For example... Figure 17 As shown, the clip connector 40 has at least one limiting protrusion 43 (clip-side limiting protrusion) provided to the base 41. The limiting protrusion 43 is disposed between any two adjacent clips 4 and protrudes from the base 41 in the -Z direction. In this modified example, when the sliding amount of the clip engaging member 5D is greater than required, the limiting surfaces 537 of any engaging portion 53A or engaging portion 53B abut against the limiting protrusion 43 before abutting against the claw portion 422A (or claw portion 422B). This allows for more appropriate suppression of excessive sliding of the clip engaging member 5D.

[0162] in addition, Figure 18 The clip engaging member 5E represents a variation of the second embodiment described above. For example... Figure 18As shown, the main body 52E of the clip engaging member 5E has a limiting protrusion 56, which is provided on the edge 535 of the engaging part 53A in the X direction, i.e., on the side of the recess 532A in the X direction, and protrudes towards the side in the Y direction (e.g., the -Y direction side).

[0163] In this modified example, when the sliding amount of the clamp engaging member 5E is greater than required, the leg 421A of each clamp 4 can abut against the limiting protrusion 56 of another engaging part 53A adjacent to the corresponding engaging part 53A in the X direction (see reference). Figure 19 Therefore, excessive sliding of the clamp engagement member 5E can be more appropriately suppressed.

[0164] In addition, Figure 18 In the example, a limiting protrusion 56 is provided correspondingly in each of the multiple engaging portions 53A, but at least one limiting protrusion 56 may also be provided in the main body portion 52E. Alternatively, the limiting protrusion 56 may be provided in each of the multiple engaging portions 53B, either in place of the multiple engaging portions 53A or together with the multiple engaging portions 53A.

[0165] Furthermore, in the second embodiment described above, the spacing between the plurality of clips 4 in the clip connector 40 and the spacing between the plurality of engaging portions 53A and 53B in the clip engaging member 5D can be arbitrarily designed.

[0166] For example, by reducing the spacing between the multiple engaging portions 53A and 53B in the clamp engaging member 5D, the installation strength can be improved. On the other hand, by increasing the spacing between the multiple engaging portions 53A and 53B in the clamp engaging member 5D, the clamp engaging member 5D can be easily bent along any curvature in the XY plane. This improves the conformability to the curvature of the groove 2A in the cushioning material 2. Furthermore, the clamp engaging member 5D can also include different spacings for the engaging portions 53A and 53B.

[0167] Alternatively, in the second embodiment described above, the limiting surface 537 may not be provided in the engaging portions 53A and 53B. In this case, the engaging portions 53A and 53B may engage with another clip 4 disposed next to the engaged clip 4 by sliding the clip engaging member 5D in the X direction.

[0168] Furthermore, the variations described in the first embodiment can also be applied in the second embodiment described above.

[0169] [Third Implementation]

[0170] Next, refer to Figure 20 and Figure 21The skin material mounting device 1B of the third embodiment of the present invention will be described.

[0171] The skin material mounting device 1B of this embodiment is designed for cushioning material 2 and skin material 3 (see reference). Figure 1 The combination of clip 4A and clip engaging member 5F in the third embodiment differs from that in the first embodiment. That is, the skin material mounting device 1B in the third embodiment includes: clip engaging member 5F, which is disposed in the groove 2A formed in the cushioning material 2; and clip 4A, which is mounted on the skin material 3.

[0172] Furthermore, the basic structure of the clip 4A and the clip engaging member 5F in this embodiment is the same as that in the first embodiment. Hereinafter, the structure that differs from that in the first embodiment will be mainly described.

[0173] The clamp 4A includes: a base 44; a pair of legs 421A and 421B disposed on the base 44; and a pair of claws 422A and 422B disposed on the pair of legs 421A and 421B, facing each other.

[0174] The base 44 has a strap 441 and a plate 442 connected to the strap 441. The strap 441 is fixed to the skin material 3 by means of sewing or the like.

[0175] The clip 4A can also be integrally molded using resin or the like. Alternatively, the non-woven fabric or similar tape 441 can be embedded relative to other parts of the clip 4A.

[0176] The clip engaging member 5F includes a base 57 and a main body 52 extending from the base 57 in the Z direction. Furthermore, in this embodiment, similar to the first embodiment described above, the extending direction of the main body 52 in the clip engaging member 5F is set to the Z direction.

[0177] In this embodiment, the base 57 is formed, for example, in a plate shape, and is connected to the groove 2A formed in the buffer material 2 (see reference). Figure 1 The bottom part is bonded. Furthermore, in this embodiment, Figure 1 The positive and negative signs of the Z direction are opposite.

[0178] The main body 52 also includes, in the same manner as in the first embodiment, a pair of side portions 521A and 521B facing opposite sides in the Y direction; engaging portions 53A and 53B formed on the pair of side portions 521A and 521B respectively; and releasing guide portions 541A and 541B formed on the pair of side portions 521A and 521B respectively.

[0179] In this embodiment, the clip 4A and the clip engaging member 5F can be engaged and disengaged through an operation that is substantially the same as that in the first embodiment.

[0180] For example, when engaging the clip 4A with the clip engaging member 5F, the operator aligns the clip 4A with the clip engaging member 5F facing each other, applying a Z-direction force to any part of the clip 4A, such as the plate portion 442, pressing the clip 4A against the clip engaging member 5F. The claw portions 422A and 422B are housed in the recesses 532A and 532B via the engaging guide portions 552A and 552B, respectively, and can abut against the engaging surfaces 533 of the engaging portions 53A and 53B. Thus, the clip 4A engages with the clip engaging member 5F, allowing the skin material 3 to be installed on the cushioning material 2.

[0181] Furthermore, when releasing the clamp 4A from the clamp engaging member 5F, the operator applies force to the clamp 4A in either the positive or negative X direction. At this time, the claw portions 422A and 422B slide relative to the guide inclined surfaces 536 of the recesses 532A and 532B, respectively, and are pulled out from the recesses 532A and 532B. Thus, the release guide portions 541A and 541B enter between the pair of claw portions 422A and 422B, replacing the engaging portions 53A and 53B as they are pulled out from between the pair of claw portions 422A and 422B.

[0182] Subsequently, the clamp 4A moves in the +Z direction by pushing the main body 52 out from between the pair of claws 422A and 422B due to the elastic force of the pair of legs 421A and 421B, and automatically disengages from the clamp engaging member 5F. As a result, the skin material 3 is removed from the cushioning material 2.

[0183] The skin material mounting device 1B according to the above embodiment achieves the same effect as the first embodiment described above.

[0184] As a variation of this embodiment, similar to the second embodiment, multiple clips 4A can also constitute a clip connector. In addition, in the clip engaging member 5F, multiple recesses 532A, 532B and multiple release guides 541A, 541B can be alternately arranged in the X direction in a pair of side portions 521A, 521B.

[0185] Furthermore, the variations described in the first and second embodiments above can also be applied to this embodiment.

[0186] [Fourth Implementation]

[0187] Next, refer to Figures 22-24The fourth embodiment of the skin material mounting device 1C of the present invention will be described. This embodiment of the skin material mounting device 1C includes a clamp 4B and a clamp engaging member 5G. The clamp 4B has a guide tilting surface 424A and a guide tilting surface 424B (claw-side guide tilting surface) instead of the clamp engaging member 5G having a guide tilting surface as described in the first to third embodiments (see...). Figure 23 , Figure 24 ).

[0188] Furthermore, the basic structure of the clip 4B and the clip engaging member 5G in this embodiment is the same as that in the first embodiment. Hereinafter, the structure that differs from that in the first embodiment will be mainly described.

[0189] The clamp 4B includes: a base 41; a pair of legs 421A and 421B disposed at the base 41; and a pair of claws 423A and 423B disposed at the legs 421A and 421B, facing each other. Wherein, as Figure 23 As shown, a pair of guide inclined surfaces 424A are formed on the claw portion 423A, such that the corner of the tip of the claw portion 423A is chamfered. Similarly, a pair of guide inclined surfaces 424B are formed on the claw portion 423B, such that the corner of the tip of the claw portion 423B is chamfered.

[0190] The pair of guide inclined surfaces 424A of the claw portion 423A are inclined relative to the X direction in such a way that they are opposite to the bottom 534 of the recess 538A (discussed later) and simultaneously opposite to the edge 535 of the recess 538A adjacent to the release guide portion 541A.

[0191] Similarly, the pair of guide inclined surfaces 424B of the claw portion 423B are inclined relative to the X direction in such a way that they are opposite to the bottom 534 of the recess 538B (discussed later) and simultaneously opposite to the edge 535 of the recess 538B adjacent to the release guide portion 541B.

[0192] The clip engaging member 5G has a base 51 and a main body 52G extending from the base 51. The main body 52G has: a pair of side parts 521A and 521B facing opposite sides in the Y direction; engaging parts 53A and 53B formed on the pair of side parts 521A and 521B; and release guide parts 541A and 541B formed on the pair of side parts 521A and 521B.

[0193] In this embodiment, recesses 538A and 538B, which open into the side portions 521A and 521B, are formed on each of the pair of side portions 521A and 521B, respectively. The engaging portions 53A and 53B in this embodiment are portions of the engaging surfaces 533 formed in the recesses 538A and 538B, respectively, within the pair of side portions 521A and 521B.

[0194] The recesses 538A and 538B are the same as in the first embodiment, except that they lack the guiding inclined surface. Specifically, recesses 538A and 538B have: a bottom 534 facing the -Y direction; and an engaging surface 533 extending from the bottom 534 in the Y direction and facing the -Z direction. Furthermore, although not particularly limited, a surface, for example perpendicular to the X direction, is formed between the bottom 534 and the edge 535 of recesses 538A and 538B.

[0195] In this embodiment, the clip 4B and the clip engaging member 5G can be engaged and disengaged through the same operation as in the first embodiment.

[0196] For example, when releasing the clamp 4B from the clamp engaging member 5G, the operator applies force to the clamp engaging member 5G in either the positive or negative X direction (e.g., the +X direction). At this time, if... Figure 24 As shown, the guide inclined surfaces 424A and 424B on the -X direction side of the claw portions 423A and 423B slide relative to the edges 535 on the -X direction side of the recesses 538A and 538B, and are pulled out from the recesses 538A and 538B.

[0197] also, Figure 24 The relative position of clamp 4B with respect to clamp engaging member 5G is schematically shown. For the legs 421A, 421B and claws 423A, 423B of clamp 4B, the position before relative movement is indicated by dashed lines and the position after relative movement is indicated by solid lines.

[0198] After the claws 423A and 423B are pulled out from the recesses 538A and 538B, the clamp engaging member 5G disengages from the clamp 4B in the same manner as in the first embodiment.

[0199] The skin material mounting device 1C according to the above embodiment achieves the same effect as the first embodiment described above.

[0200] In addition, in this embodiment, two guide inclined surfaces 424A and 424B are formed in each claw portion 423A and 422B. Therefore, when releasing the clamp 4B from the clamp engaging member 5G, the operator can slide the clamp engaging member 5G in either the positive or negative direction of the X direction.

[0201] Furthermore, the variations described in the first to third embodiments above may also be appropriately applied to this embodiment.

[0202] For example, in this embodiment, similar to the second embodiment described above, multiple clips 4B can also constitute a clip connector, and the clip engaging member 5G can also have multiple engaging portions 53A, engaging portions 53B and multiple release guide portions 541A, 541B that are alternately arranged relative to the engaging portions 53A, engaging portions 53B in the X direction.

[0203] Alternatively, in each of the claw portions 423A and 423B, a guide inclined surface 424A and a guide inclined surface 424B may be formed only on either side in the X direction.

[0204] [Fifth Implementation]

[0205] Next, refer to Figures 25-27 The skin material mounting device of the fifth embodiment of the present invention will be described.

[0206] The skin material mounting device of this embodiment has a clip engaging member 5K with a shape different from that of the first embodiment and a clip 4 the same as that of the first embodiment. Hereinafter, the clip engaging member 5K will be described.

[0207] The clamp engaging member 5K has a base 51 and a main body 52K extending from the base 51 in the +Z direction, the same as in the first embodiment. The main body 52K has a pair of side portions 521A and 521B facing opposite sides in the Y direction.

[0208] also, Figure 25 , Figure 26 The side portion 521A is indicated by a pair of side portions 521A and 521B. In this embodiment, the pair of side portions 521A and 521B have a shape that is symmetrical with respect to the XZ plane.

[0209] A recess 532A with an opening is formed on side portion 521A, and a recess 532B with an opening is formed on side portion 521B. A bottom 534 and two guide inclined surfaces 536 disposed in the X direction, separated by the bottom 534, are formed in recesses 532A and 532B, respectively. The guide inclined surfaces 536 extend from the bottom 534 to the edge 535 of recesses 532A and 532B while being inclined relative to the X direction.

[0210] Furthermore, in the side portions 521A and 521B of this embodiment, on the +Z side of the recesses 532A and 532B, a plurality of protrusions 61 are formed that protrude in the Y direction relative to the bottom 534 of the recesses 532A and 532B and are arranged along the X direction. These plurality of protrusions 61 constitute the engaging portions 53A and 53B of this embodiment (see reference). Figure 27 ).

[0211] Furthermore, the protrusion height of the protrusion 61 in the Y direction is set to be the same as or lower than the edge 535 of the recess 532A and the recess 532B.

[0212] Furthermore, in this embodiment, side portions 521A and 521B are each formed with a stepped shape that extends from the protrusion 61 toward the +Z side and toward the inward side in the Y direction. Each of the plurality of stepped portions 62 is disposed corresponding to each of the plurality of protrusions 61. These plurality of stepped portions 62 constitute the engagement guide portions 552A and 552B of this embodiment (see reference). Figure 27 ).

[0213] Furthermore, in this embodiment, the release guide portion 541A and the release guide portion 541B are respectively configured as planar shapes arranged along the XZ plane.

[0214] Furthermore, in the side portions 521A and 521B of this embodiment, on the -Z side of the recesses 532A and 532B, a plurality of protrusions 63 are formed that protrude in the Y direction relative to the bottom 534 of the recesses 532A and 532B and are arranged along the X direction. These plurality of protrusions 63 constitute the protrusions of this embodiment.

[0215] In this embodiment described above, the clip 4 and the clip engaging member 5K can be engaged and disengaged through an operation that is substantially the same as that in the first embodiment.

[0216] Furthermore, in this embodiment, the engaging guide portion 552A, engaging guide portion 552B, releasing guide portion 541A, and releasing guide portion 541B do not have an inclined surface that is tilted relative to the Z direction. That is, the engaging guide portion 552A and engaging guide portion 552B have a stepped shape, and the releasing guide portion 541A and releasing guide portion 541B have a planar shape. Therefore, the cost associated with the mold used to form the clamp engaging member 5K can be reduced.

[0217] Specifically, the manufacturing apparatus for the molded resin clamping component 5K has a pair of rollers, and the clamping component 5K can be continuously and integrally molded by injecting resin between the pair of rollers. The rollers are a rotating mold composed of multiple stacked plates, and the rotation axis of each roller corresponds to the Z direction of the clamping component 5K.

[0218] Assuming the clamp engaging member 5 of the first embodiment is manufactured using the aforementioned manufacturing apparatus, the plate for forming inclined surfaces (e.g., engaging guide portion 552A, engaging guide portion 552B, releasing guide portion 541A, releasing guide portion 541B) in the Z-direction of the clamp engaging member 5 needs to be a plate with a large thickness in the direction of the rotation axis. Manufacturing such a plate requires multi-axis machining, and replacement costs are high when the plate breaks.

[0219] On the other hand, in the clamp engaging member 5K of this embodiment, the engaging guide portion 552A, engaging guide portion 552B, releasing guide portion 541A, and releasing guide portion 541B do not have inclined surfaces that are inclined in the Z direction. Therefore, when the clamp engaging member 5K of this embodiment is manufactured using the above-described manufacturing apparatus, the thickness of each plate constituting the roller can be reduced. Such plates can be manufactured using wire electrical discharge machining, thus reducing the replacement cost when the plates break.

[0220] Furthermore, in this embodiment, the engaging portions 53A and 53B are composed of a plurality of protrusions 61 arranged in the X direction, and the engaging guide portions 552A and 552B are composed of a plurality of stepped portions 62 arranged in the X direction. That is, in the clip engaging member 5K of this embodiment, the elements protruding in the Y direction are discontinuously formed in the X direction. With such a structure, when the groove 2A of the buffer material 2 has a curved shape, it is easy to insert the clip engaging member 5K into the groove 2A while bending it.

[0221] Furthermore, as a variation of this embodiment, similar to the second embodiment, multiple recesses 532A, 532B and multiple release guides 541A, 541B may be alternately arranged in the X direction in a pair of side portions 521A, 521B of the clip engaging member 5K. In other words, Figure 25 , Figure 26The structure of the clamping member 5K shown can be regarded as a local structure in the X direction.

[0222] Alternatively, as a variation of this embodiment, the engaging portion 53A and engaging portion 53B may each be composed of a single protrusion 61. Similarly, the engaging guide portion 552A and engaging guide portion 552B may each be composed of a single stepped portion 62.

[0223] Furthermore, the variations described in the other embodiments above can also be applied to this embodiment.

[0224] [Other variations]

[0225] In the first to third and fifth embodiments described above, the structure in which a guide inclined surface 536 is formed in the recesses 532A and 532B of the clamp engaging member 5, the clamp engaging member 5A to the clamp engaging member 5F, and the clamp engaging member 5K is described. In the fourth embodiment described above, the structure in which a guide inclined surface 424A and a guide inclined surface 424B are formed in the claw portion 423A and the claw portion 423B of the clamp 4B is described. However, the present invention is not limited to these.

[0226] For example, in the first to third and fifth embodiments described above, a guide inclined surface 536 may be formed on the clip engaging member 5, clip engaging member 5A to clip engaging member 5F, and clip engaging member 5K, and / or, a guide inclined surface as in the fourth embodiment may be formed on the clip 4 and clip 4A instead of forming a guide inclined surface 536 on the clip engaging member 5, clip engaging member 5A to clip engaging member 5F, and clip engaging member 5K.

[0227] Alternatively, in the above embodiments, the guide inclined surfaces 536, 424A, and 424B may not be formed. For example, a small step may be provided between the bottom 534 of the recesses 532A and 532B and the edge 535 adjacent to the release guide portions 541A and 541B, so that the claw portions 422A and 422B can be positioned so that they can be placed on the release guide portions 541A and 541B from the recesses 532A and 532B due to the user's operating force.

[0228] In the above embodiments, recesses 532A and 532B are formed on the side portions 521A and 521B, and engaging portions 53A and 53B are formed to include engaging surfaces 533 formed on the recesses 532A and 532B, but the present invention is not limited thereto.

[0229] For example, the recesses 532A and 532B may not be formed on the side portions 521A and 521B, but the protrusions protruding from the side portions 521A and 521B may be formed as engaging portions 53A and 53B, and the side of the protrusions may be formed as engaging surfaces 533.

[0230] In the above embodiments, the clip 4, clips 4A to 4B, and clip engaging members 5, clip engaging members 5A to 5G, and clip engaging members 5K each have a shape that is symmetrical with respect to the XZ plane, but the present invention is not limited thereto.

[0231] For example, such as Figure 28 As shown, the skin material mounting device 1D may also include a clip 4C and a clip engaging member 5H that are asymmetrical with respect to the XZ plane. The clip 4C has a base 41, a pair of legs 421A and 421B, and a claw 422A attached to either leg (e.g., leg 421A). The clip engaging member 5H has an engaging portion 53A formed on either of the pair of side portions 521A and 521B (e.g., side portion 521A); and a release guide portion (not shown), which is adjacent to the engaging portion 53A in the X direction. Furthermore, the shapes of the legs 421B and the side portions 521B are not particularly limited; for example, it is preferable that the legs 421B support the side portions 521B from one side in the Y direction while not interfering with the side portions 521B in the Z direction.

[0232] In the above embodiments, the clamp engaging member 5, clamp engaging members 5A to 5G, and clamp engaging member 5K have release guide portions 541A and 541B, but the present invention is not limited thereto.

[0233] For example, such as Figure 29 As shown, the clamp engaging member 5J may also have a slit 58 instead of the release guide portion 541A and release guide portion 541B. That is, in the clamp engaging member 5J having multiple engaging portions 53A and 53B, the slit 58 cut into the main body portion 52J can also serve as the claw portion 422A and claw portion 422B that guide the clamp 4 along the Z-axis direction (see example). Figure 3 The slit 58 functions as a release guide. The slit 58 has a shape where adjacent engaging portions 53A (or engaging portions 53B) along the X direction cut into the main body 52J from the top end in the Y-axis direction. Alternatively, the slit 58 may be formed at one end of the main body 52J in the X direction, i.e., at a position further outward in the X direction than the leading or trailing engaging portions 53A and 53B among the plurality of engaging portions 53A and 53B arranged in the X direction.

[0234] In this structure, the main body 52J can be pulled out from the clip 4 by performing the same operation as in the above embodiments.

[0235] The various components in the embodiments and variations described above can be appropriately combined.
