Summary of the Invention

Problems to be Solved by the Invention

[0004] Since the sliding sheet of Patent Document 1 has insufficient flexibility, the degree of freedom of deformation is low. For this reason, in the sliding sheet of Patent Document 1, it is impossible to achieve both a high degree of freedom of deformation and a lubricating effect.

[0005] An object of the present disclosure is to provide a low-friction member, a motion mechanism, and clothing that can achieve both a high degree of freedom of deformation and a lubricating effect.

Means for Solving the Problems

[0006] A first aspect includes a base body having an attachment surface and capable of elastic deformation, and a plurality of low-friction materials attached to the attachment surface and having a lower coefficient of friction than the base body. A part of the low-friction material is attached to the attachment surface, and a non-attached portion that is not attached to the attachment surface is overlapped on another low-friction material.

[0007] In the first aspect, a part of the low-friction material is attached to the mounting surface of the base body. Therefore, compared with the case where the entire low-friction material is attached to the mounting surface of the base body, the deformation of the base body is less likely to be restricted, and thus the degree of freedom of deformation of the base body is high.

[0008] Moreover, the non-attached portion of the low-friction material that is not attached to the mounting surface is overlapped on another low-friction material. Therefore, when the low-friction materials slide relative to each other, it is possible to suppress the interference between the low-friction materials, such as the low-friction materials getting caught on each other.

[0009] As a result, when the low-friction member is applied, for example, between sliding elements that slide relative to each other, it is possible to achieve both a high degree of freedom of deformation and a lubricating effect.

[0010] In the second aspect, in the first aspect, the non-attached portion of the low-friction material is overlapped on the attached portion attached to the mounting surface in the other low-friction material.

[0011] According to the second aspect, since the non-attached portion of the low-friction material is overlapped on the attached portion of the other low-friction material, when the low-friction materials slide relative to each other, it is possible to suppress the interference between the low-friction materials, such as the low-friction materials getting caught on each other, as compared with a configuration in which the non-attached portion of the low-friction material is overlapped only on the non-attached portion of the other low-friction material.

[0012] In the third aspect, in the second aspect, a plurality of the low-friction materials are attached along a predetermined attachment direction with respect to the mounting surface, one end portion in the attachment direction is attached to the mounting surface, and the other end portion in the attachment direction as the non-attached portion that is not attached to the mounting surface is overlapped on the one end portion of the other low-friction material.

[0013] According to the third aspect, since the other end portion in the mounting direction of the low-friction material is overlapped on one end portion in the mounting direction of the other low-friction material, when the low-friction materials slide relative to each other, compared with a configuration in which the other end portion in the mounting direction of the low-friction material is overlapped only on the other end portion in the mounting direction of the other low-friction material, it is possible to suppress the low-friction materials from interfering with each other, such as being caught on each other.

[0014] In the fourth aspect, in the third aspect, the mounting dimension along the mounting direction of the low-friction material attached to the mounting surface is smaller than the non-mounting dimension along the mounting direction of the low-friction material not attached to the mounting surface.

[0015] According to the fourth aspect, since the mounting dimension is smaller than the non-mounting dimension, compared with a configuration in which the mounting dimension is larger than the non-mounting dimension, the deformation of the base is less likely to be restricted, so the degree of freedom of deformation of the base is high.

[0016] In the fifth aspect, in any one of the first to fourth aspects, the base is formed in a sheet shape having a front surface and a back surface, and the low-friction material is attached to at least one of the front surface and the back surface as the mounting surface.

[0017] As in the fifth aspect, it is possible to use a base formed in a sheet shape having a front surface and a back surface as the base, and to use a low-friction material attached to at least one of the front surface and the back surface as the mounting surface as the low-friction material.

[0018] In the sixth aspect, in any one of the first to fifth aspects, the base is formed in a sheet shape elongated in one direction, is stretchable along the longitudinal direction, and is bendable in a direction orthogonal to the thickness direction and the longitudinal direction and in the thickness direction.

[0019] According to the sixth aspect, the base body is stretchable along the longitudinal direction and bendable in the orthogonal direction and the thickness direction. And a part of the low-friction material is attached to the mounting surface of the base body. For this reason, compared with the case where all of the low-friction material is attached to the mounting surface of the base body, the deformation of the base body is less likely to be restricted, so the degrees of freedom of expansion / contraction and bending deformation in the base body are high.

[0020] The seventh aspect is a motion mechanism including a first element having a first surface, a second element having a second surface facing the first surface side and relatively moving with respect to the first element, and a low-friction member disposed between the first surface and the second surface. The low-friction member has a first mounting surface facing the first surface side and a second mounting surface facing the second surface side, and includes an elastically deformable base body, and a plurality of low-friction materials attached to each of the first mounting surface and the second mounting surface and having a lower coefficient of friction than the base body. A part of the low-friction material is attached to each of the first mounting surface and the second mounting surface, and a non-attached portion not attached to each of them is overlapped on the other low-friction material. In the seventh aspect, as the low-friction member, any one of the low-friction members of the first to sixth aspects can be used.

[0021] The eighth aspect is a piece of clothing including an inner and a low-friction member attached to the outer surface of the inner. The low-friction member has a first mounting surface facing the outer surface of the inner and a second mounting surface facing the side opposite to the outer surface, and includes an elastically deformable base body, and a plurality of low-friction materials attached to each of the first mounting surface and the second mounting surface and having a lower coefficient of friction than the base body. A part of the low-friction material is attached to each of the first mounting surface and the second mounting surface, and a non-attached portion not attached to each of them is overlapped on the other low-friction material. In the eighth aspect, as the low-friction member, any one of the low-friction members of the first to sixth aspects can be used.

[0022] In the seventh and eighth aspects, a part of the low-friction material is attached to each of the first attachment surface and the second attachment surface. Therefore, compared with the case where the entire low-friction material is attached to each of the first attachment surface and the second attachment surface of the base body, the deformation of the base body is less likely to be restricted, and thus the degree of freedom of deformation of the base body is high.

[0023] In addition, the non-attached portions of the low-friction material that are not attached to each of the first attachment surface and the second attachment surface are stacked on other low-friction materials. For this reason, when the low-friction materials slide relative to each other, it is possible to suppress the interference between the low-friction materials, such as the low-friction materials getting caught on each other. As a result, it is possible to achieve both a high degree of freedom of deformation and a lubricating effect.

Advantages of the Invention

[0024] According to the present disclosure, with the above configuration, it is possible to achieve both a high degree of freedom of deformation and a lubricating effect.

Modes for Carrying Out the Invention

[0026] Hereinafter, embodiments of the present disclosure will be described. However, the present disclosure is not limited to the following embodiments. In the following embodiments, the components are not essential unless otherwise specified.

[0027] When describing embodiments with reference to the drawings in the present disclosure, the configuration of the embodiment is not limited to the configuration shown in the drawings. Also, the sizes of the components in each figure are conceptual. Therefore, the front-back, left-right, and up-down dimensional ratios of each component, and the front-back, left-right, and up-down dimensional ratios between the components are not limited to the illustrated dimensional ratios. Also, the front-back, left-right, and up-down dimensional ratios of each component may be different from the actual ones.

[0028] Also, unless otherwise specified in the specification, the number of each component of the present disclosure is not limited to one, and a plurality may exist. In the following description of the drawings, the same parts are denoted by the same reference numerals.

[0029] <Low-friction sheet 10> The low-friction sheet 10 according to this embodiment will be described. FIG. 1 is a perspective view showing the low-friction sheet 10. FIG. 2 is a perspective view showing a state in which the other end portion 32B of the low-friction material 30 described later is separated from the base body 20 in the low-friction sheet 10. FIG. 3 is a plan view showing the low-friction sheet 10. FIG. 4 is a side view showing the low-friction sheet 10.

[0030] The low-friction sheet 10 is an example of a low-friction member. The low-friction material 30 is, for example, a sheet material that can reduce the friction between sliding elements that slide relative to each other by being disposed between the sliding elements. Specifically, as shown in FIGS. 1, 2, and 3, the low-friction sheet 10 includes a base body 20 and a low-friction material 30. Hereinafter, each part of the low-friction sheet 10 will be described.

[0031] <Base body 20> The base body 20 has an attachment surface 22 and is a structure capable of elastic deformation. This base body 20 is the main part of the low-friction sheet 10 and is the part forming the framework. Specifically, the base body 20 is formed in a sheet shape having a front surface 22A and a back surface 22B as the attachment surface 22. Hereinafter, the attachment surface 22 is used as a concept including the front surface 22A and the back surface 22B.

[0032] In the present embodiment, the base body 20 is elongated in one direction (Z direction) and is formed in a rectangular shape (in other words, strip shape) when viewed in the thickness direction (X direction). In the present embodiment, the base body 20 is made stretchable along the longitudinal direction (Z direction) (see FIG. 4) and is made bendable in the short-side direction (Y direction) and the thickness direction (X direction) (see FIGS. 3 and 4). The thickness direction (X direction), the longitudinal direction (Z direction), and the short-side direction (Y direction) are directions orthogonal to each other.

[0033] As the base body 20, for example, one having a lower rigidity than the low-friction material 30 is used. Specifically, the base body 20 is formed of an elastic material such as urethane or rubber, for example.

[0034] <Modification example of the base body 20> The base body 20 may have holes, notches, etc. formed therein. The holes, notches can be formed, for example, so as to penetrate the base body 20 in the thickness direction.

[0035] In the present embodiment, the base body 20 is in a sheet shape and is formed in a rectangular shape (in other words, strip shape), but it is not limited thereto. As the shape of the base body of the present disclosure, various shapes can be used.

[0036] In the present embodiment, the base body 20 is formed in a sheet shape having a front surface 22A and a back surface 22B as the attachment surface 22, but it is not limited thereto. As the base body of the present disclosure, it suffices to have at least one attachment surface 22.

[0037] Also, as long as the base body 20 is capable of elastic deformation, its material is not limited, and various materials can be used.

[0038] <Low friction material 30> The low friction material 30 is formed of a member having a lower coefficient of friction than the base body 20. The low friction material 30 is formed in a strip shape (i.e., a rectangular sheet shape). The length of the low friction material 30 in one direction (Z direction) is shorter than the length of the base body 20 in one direction (Z direction). Further, as the low friction material 30, for example, paper coated with Teflon resin or release paper can be used.

[0039] A plurality of the low friction materials 30 are attached to each of the front surface 22A and the back surface 22B of the base body 20. Specifically, a plurality of the low friction materials 30 are attached along a predetermined attachment direction (Z direction) with respect to the attachment surface 22. In the present embodiment, one end portion 32A in the attachment direction of each low friction material 30 is attached to the attachment surface 22, and the other end portion 32B in the attachment direction is not attached to the attachment surface 22. The other end portion 32B is overlapped on the one end portion 32A of another low friction material 30.

[0040] Note that one end portion 32A of the low friction material 30 can be attached to the attachment surface 22 by joining means such as adhesion or welding.

[0041] In the present embodiment, each of the plurality of low friction materials 30 arranged along the attachment direction (Z direction) has its other end portion 32B sequentially overlapped on the one end portion 32A of the low friction material 30 adjacent in the attachment direction, so that the low friction sheet 10 has a scale-like structure. Note that in the present embodiment, the other end portion 32B of the low friction material 30 is overlapped on the one end portion 32A of one low friction material 30.

[0042] As described above, in the present embodiment, a part of the low friction material 30 is attached to the attachment surface 22. Further, in the present embodiment, in the low friction material 30, a non-attached portion that is not attached to the attachment surface 22 is overlapped on the attached portion attached to the attachment surface 22. In the present embodiment, one end portion 32A of the low friction material 30 is an example of an attached portion attached to the attachment surface 22, and the other end portion 32B of the low friction material 30 is an example of a non-attached portion that is not attached to the attachment surface 22.

[0043] Furthermore, in the low friction material 30, the other end portion 32B that is not attached to the attachment surface 22 is allowed to move relative to the attachment surface 22. Specifically, the other end portion 32B is movable in a direction away from the attachment surface 22 (a direction orthogonal to the attachment surface 22) and in a direction along the attachment surface 22.

[0044] Also, at one end portion 32A of each low friction material 30, the attachment dimension (the dimension along the attachment direction (Z direction)) attached to the attachment surface 22 is smaller than the non-attachment dimension (the dimension along the attachment direction (Z direction)) that is not attached to the attachment surface 22 at the other end portion 32B of each low friction material 30. Specifically, the attachment dimension is set in a range of, for example, 1% or more and less than 50% with respect to the overall dimension including the attachment dimension and the non-attachment dimension. The attachment dimension is set in a range of, for example, 1 mm or more and 10 mm or less.

[0045] Furthermore, the low friction material 30 is attached to the back surface 22B at an attachment position that overlaps in the thickness direction with respect to the attachment position with respect to the front surface 22A. That is, the attachment position of the low friction material 30 with respect to the front surface 22A and the attachment position of the low friction material 30 with respect to the back surface 22B overlap when viewed in the thickness direction of the base body 20.

[0046] <Modification example of the low friction material 30> In the present embodiment, the low friction material 30 uses paper or release paper coated with Teflon resin, but is not limited thereto. As the low friction material of the present disclosure, the material is not limited as long as it is a member having a lower friction coefficient than the base body 20, and various materials can be used.

[0047] Also, in the present embodiment, the low-friction material 30 was formed in a strip shape (i.e., a rectangular sheet shape), but it is not limited to this. The shape of the low-friction material of the present disclosure may be, for example, linear, rod-shaped, etc., and various shapes can be used. Note that the overall shape of the low-friction sheet 10 does not necessarily have to be sheet-shaped, and it can be various shapes depending on the shapes of the low-friction material 30 and the base 20.

[0048] Also, in the present embodiment, a plurality of the low-friction materials 30 were attached to each of the front surface 22A and the back surface 22B of the base 20, but it is not limited to this. As the low-friction material of the present disclosure, it may be attached to only one of the front surface 22A and the back surface 22B of the base 20. That is, as the low-friction material of the present disclosure, it only needs to be attached to at least one attachment surface.

[0049] Also, in the present embodiment, a plurality of the low-friction materials 30 were attached along a predetermined attachment direction (Z direction) with respect to the attachment surface 22, but it is not limited to this. Each low-friction material 30 may be attached along a plurality of directions, and as the low-friction material of the present disclosure, it can be attached in any direction.

[0050] Also, in the present embodiment, the other end portion 32B of the low-friction material 30 was overlapped on the one end portion 32A of another low-friction material 30, but it is not limited to this. As the low-friction material of the present disclosure, the other end portion (non-attached portion) may be overlapped on the other end portion (non-attached portion) of another low-friction material, and it only needs to be overlapped on any part of the low-friction material.

[0051] Also, in the present embodiment, the other end portion 32B of the low-friction material 30 was overlapped on the one end portion 32A of one low-friction material 30, but it is not limited to this. As the low-friction material of the present disclosure, the other end portion 32B of the low-friction material 30 may be overlapped on a plurality of low-friction materials.

[0052] In addition, in this embodiment, the mounting dimension of the low-friction material 30 is smaller than the non-mounting dimension, but the present invention is not limited to this. As the low-friction material of the present disclosure, the mounting dimension may be larger than the non-mounting dimension.

[0053] In addition, in this embodiment, the mounting position with respect to the front surface 22A of the low-friction material 30 and the mounting position with respect to the back surface 22B of the low-friction material 30 overlap when viewed in the thickness direction of the base 20, but the present invention is not limited to this. As the low-friction material of the present disclosure, the mounting position with respect to the front surface 22A of the low-friction material and the mounting position with respect to the back surface 22B of the low-friction material may be offset when viewed in the thickness direction of the base 20.

[0054] <Function and effect of the low-friction sheet 10> In the low-friction sheet 10 of this embodiment, a part of the low-friction material 30 is attached to the attachment surface 22 of the base 20. Therefore, compared with the case where the entire low-friction material 30 is attached to the attachment surface 22 of the base 20, the deformation of the base 20 is less likely to be restricted, and the degree of freedom of deformation of the base 20 is high.

[0055] In particular, in this embodiment, since the mounting dimension of the low-friction material 30 is smaller than the non-mounting dimension, the deformation of the base 20 is less likely to be restricted compared with a configuration in which the mounting dimension is larger than the non-mounting dimension, so the degree of freedom of deformation of the base 20 is high.

[0056] Furthermore, in this embodiment, the base 20 is made to be stretchable along the longitudinal direction (Z direction), and bendable in the short-side direction (Y direction) and the thickness direction (X direction), so that the degree of freedom of three-directional deformation by the base 20 is increased.

[0057] In addition, the other end portion 32B that is not attached to the attachment surface of the low-friction material 30 is overlapped on another low-friction material 30. Therefore, when the low-friction materials 30 slide relative to each other, it is possible to suppress the interference between the low-friction materials 30, such as the low-friction materials 30 getting caught on each other.

[0058] In this embodiment, since the other end portion 32B of the low-friction material 30 is overlapped with the one end portion 32A which is the attachment portion of the other low-friction material 30, when the low-friction materials 30 slide relative to each other, the interference between the low-friction materials 30 is suppressed, such as the low-friction materials 30 getting caught on each other, as compared with a configuration where the other end portion 32B of the low-friction material 30 is overlapped only with the other end portion 32B which is the non-attachment portion of the other low-friction material 30.

[0059] As a result, according to the low-friction sheet 10, for example, when applied between sliding elements that slide relative to each other, it is possible to achieve both a high degree of freedom in deformation and a lubricating effect.

[0060] <Examples of application of the low-friction sheet 10> As an example, the low-friction sheet 10 can be applied to the following motion mechanism 50 and clothing 80. Hereinafter, the motion mechanism 50 and the clothing 80 will be described.

[0061] <Motion mechanism 50> FIG. 5 is a perspective view showing the motion mechanism 50. As shown in FIG. 5, the motion mechanism 50 includes six motion units 51, 52, 53, 54, 55, 56 (hereinafter referred to as 51 to 56), a drive device 59, and a plurality (specifically, six) of low-friction sheets 10.

[0062] Each of the motion units 51 to 56 is a unit that performs a bending motion when driven by the drive device 59. The motion units 51 to 56 are similarly configured. Therefore, hereinafter, the motion unit 51 will be taken as an example for explanation, and the description of the other motion units 52, 53, 54, 55, 56 will be omitted.

[0063] The motion unit 51 includes a plurality (specifically, five) of blocks 60 arranged along a predetermined arrangement direction (the Z direction in FIG. 5). The block 60 is formed in a frustum of a hexagonal pyramid shape having a top surface 61, a bottom surface 62, and six side surfaces 63. In the block 60 having the frustum of a hexagonal pyramid shape, of the two hexagonal surfaces, the surface with the smaller area is defined as the top surface 61, and the surface with the larger area is defined as the bottom surface 62. Also, in the block 60, the surfaces formed in a trapezoidal shape, excluding the top surface 61 and the bottom surface 62, are the side surfaces 63.

[0064] In the motion unit 51, when a plurality of blocks 60 are arranged in the arrangement direction, two of the six side surfaces 63 are arranged along the arrangement direction. The two side surfaces 63 constitute the side surfaces 68 and 69 (see FIG. 5) of the motion unit 51.

[0065] As an example, the block 60 is formed of an elastic body such as urethane foam. The blocks 60 adjacent to each other in the arrangement direction are joined at the corner portions 64. Thereby, the motion unit 51 is configured such that the five blocks 60 can bend in conjunction with each other.

[0066] In each block 60, a pair of through holes 65 penetrating in the arrangement direction are formed. A wire 66 driven by a drive device 59 is passed through each of the pair of through holes 65. Specifically, the wire 66 is formed of a shape memory alloy and contracts by energization heating by the drive device 59. Although not shown in FIG. 5, the wire 66 is also passed through each of the pair of through holes 65 in the motion units 52, 53, 54, 55, and 56.

[0067] The motion units 51 to 56 are arranged along the circumferential direction (the A direction in FIG. 5) such that the top surface 61 of the block 60 faces the inner peripheral side and the bottom surface 62 of the block 60 faces the outer peripheral side.

[0068] The motion units 51 to 56 are such that the side surface 68 and the side surface 69 face each other in the circumferential direction adjacent motion units. That is, each side surface 68 of the motion units 51 to 56 faces the side surface 69 side of the circumferentially adjacent motion unit.

[0069] And the aforementioned low-friction sheet 10 is disposed between each side surface 68 and side surface 69 of the motion units 51 to 56. Each of the plurality of low-friction sheets 10 is attached by an attachment portion 67 provided on the bottom surface 62 of the block 60.

[0070] In the low-friction sheet 10, the front surface 22A of the base 20 faces the side surface 68 side, and the back surface 22B of the base 20 faces the side surface 69 side. Then, the low-friction material 30 attached to the front surface 22A comes into contact with the side surface 68. The low-friction material 30 attached to the back surface 22B comes into contact with the side surface 69.

[0071] And in the motion mechanism 50, the drive device 59 contracts the wire 66 by energization heating to bend at least one of the motion units 51 to 56. Thereby, at least one of the motion units 51 to 56 relatively moves with respect to the other motion units.

[0072] At this time, at least one of the motion units 51 to 56 slides with respect to the low-friction sheet 10, and the lubricating effect by the low-friction sheet 10 is exhibited. Thereby, in the motion mechanism 50, following and sliding are possible between the motion units 51 to 56.

[0073] And the low-friction sheet 10, as described above, can achieve both a high degree of freedom of deformation and a lubricating effect. For this reason, in the motion mechanism 50, by selecting the motion units 51 to 56 to be bent, a bending motion with a high degree of freedom of deformation becomes possible.

[0074] In the motion mechanism 50, for example, it is possible to regard the motion unit 51 as an example of the first element and the motion unit 52 as an example of the second element. It is possible to regard the side surface 68 of the motion unit 51 as an example of the first surface and the side surface 69 of the motion unit 52 as an example of the second surface. Further, it is possible to regard the surface 22A of the base 20 in the low-friction sheet 10 as an example of the first attachment surface and the back surface 22B of the base 20 as an example of the second attachment surface.

[0075] <Modification example of the motion mechanism 50> The motion mechanism 50 is a mechanism that performs a bending motion by the motion units 51 to 56, but is not limited thereto. As the motion mechanism of the present disclosure, for example, a robot, a transportation machine, a conveying device, etc. may be used, and any mechanism having elements that move relative to each other (specifically, sliding elements that slide relative to each other) to which the low-friction member of the present disclosure is applicable may be used.

[0076] <Clothing 80> FIG. 6 is a perspective view showing the clothing 80. The clothing 80 is a pannier having a pannier body 82 and the aforementioned low-friction sheet 10. The pannier is an inner worn inside a skirt (i.e., an outer) for the purpose of giving shape retention and volume.

[0077] The pannier body 82 is formed, for example, in a skirt shape, specifically, in a cylindrical shape having a larger diameter at the lower end than at the upper end. The pannier body 82 is formed of fibers such as natural fibers and chemical fibers, for example.

[0078] A plurality of low-friction sheets 10 are attached to the outer periphery of the pannier body 82. Specifically, with respect to one end portion 32A of the low-friction material 30, a part (specifically, the upper end portion) of the low-friction sheet 10 is attached to the outer surface of the pannier body 82 in a state where the other end portion 32B faces downward. The lower portion of the upper end portion of the low-friction sheet 10 is not attached to the pannier body 82. The plurality of low-friction sheets 10 are attached along the circumferential direction of the pannier body 82 and also along the axial direction of the pannier body 82. As a result, the clothing 80 has a scaly structure of the low-friction sheet 10 with respect to the pannier body 82 in addition to the scaly structure of the low-friction sheet 10 itself.

[0079] According to the clothing 80, the lubricating effect of the low-friction sheet 10 reduces the friction with the outer wear. As a result, damage (for example, fraying, damage, color fading) of the clothing 80 can be suppressed. Furthermore, due to the high degree of freedom of deformation of the low-friction sheet 10, a comfortable wearing feeling can be realized. Also, the scaly structure in the clothing 80 enables the clothing 80 to have shape retention and volume.

[0080] Note that the pannier body 82 is an example of an inner wear. Also, it is possible to regard the surface 22A of the base 20 in the low-friction sheet 10 as an example of a first attachment surface and the back surface 22B of the base 20 as an example of a second attachment surface.

[0081] <Modification example of the clothing 80> In the present embodiment, a pannier is used as the clothing 80, but it is not limited thereto. For example, as the clothing of the present disclosure, a petticoat, other inner wears worn on the lower body, or inner wears worn on the upper body may be used, and various types of clothing can be used.
