  Since the auxiliary tool described in Patent Document 1 is configured to be foldable in the width direction as described above, the width of the instrument can be secured when the folded portion is widened. As described above, the auxiliary tool disclosed in Patent Document 1 has a certain width so that the user can easily leave the weight in the instrument. Therefore, it is possible to sit on the instrument stably. However, while the user can sit on the device stably, the friction between the user and the device increases as the user puts the weight on the device, which may make it difficult for the user to move smoothly on the device. is there.

  An object of the present invention is to provide an auxiliary tool for moving a human body that is easy to move smoothly even if a user deposits his / her weight.

An auxiliary tool for moving a human body according to the present invention includes a main body including a human body placing portion having a placement surface on which a human body is placed, and extends along the placement surface and straddles the placement surface in one direction. and a moving sheet, the moving sheet, from one end of the body mounting portion about said one direction to the other, as well as a possible feed while being in contact with the placement surface, to the one end from the other end, It is wound around the main body so that it can be fed out in contact with the placement surface, and the human body placement portion includes a surface layer that forms the placement surface, and a material that constitutes the surface layer. Includes an inner layer made of a different material and in contact with the surface layer, the surface layer being a fixed sheet fixed to the inner layer, and a surface in front of the placement surface in the moving sheet and the front In relation to the feeding direction of the moving sheet between the placement surfaces The dynamic friction coefficient is adjusted so as to be smaller than the dynamic friction coefficient in the direction perpendicular to the feeding direction of the moving sheet between the surface in contact with the mounting surface in the moving sheet and the mounting surface .

According to the present invention, the moving sheet is wound up so that it can be fed out from one end of the placement surface through the placement surface toward the other end of the placement surface (or the opposite direction). Therefore, by making the moving sheet slippery with respect to the mounting surface compared to the slipperiness of the human body with respect to the mounting surface, even if the user sitting on the moving sheet deposits weight on the main body part over the moving sheet, It is easy to move smoothly along the main body while sliding the moving sheet with respect to the placement surface.

Further, in the present invention, the main body portion includes a support portion that supports the human body placement portion from the side opposite to the placement surface, and the one body portion is interposed between the human body placement portion and the support portion. A penetrating space is formed along a direction, and the movable sheet passes through the penetrating space along the one direction and extends so as to surround the human body placing portion, and the fixed sheet is the inner layer. It is preferable to extend so that it may surround . According to this, the movable sheet is movable through the through space formed between the human body placing part and the support part. For this reason, even if it is a case where a support part is arranged on a bed or a wheelchair so as to support a human body placement part on a bed or a wheelchair, for example, the weight of the user may be applied to the movable seat in the through space. Absent. Therefore, it is easy to move the moving sheet.

In the present invention, dynamic friction coefficient between the surface and the mounting surface in contact with the placement surface in the moving sheet, the surface of the inner layer and the mounting surface and contact surfaces of the moving sheet The material constituting the surface layer and the material constituting the inner layer are preferably adjusted so as to be smaller than the dynamic friction coefficient between the surfaces in contact with the layer. According to this, a surface layer having a smaller friction with the moving sheet than the inner layer is formed. For this reason, it is easier to move the moving sheet than when the moving sheet and the inner layer are in direct contact.

It is a perspective view of the auxiliary tool which concerns on one Embodiment of this invention. Fig.1 (a) and FIG.1 (b) are the figures seen from the mutually opposite side. FIG. 1A is drawn so that the fixed sheet is partially exposed from below the moving sheet in the configuration of the auxiliary tool. It is a disassembled perspective view of the auxiliary tool shown in FIG.1 (b). It is sectional drawing regarding the one cross section orthogonal to A direction in the mounting board shown in FIG. It is a fragmentary sectional view regarding one cross section orthogonal to the B direction in the auxiliary tool shown in FIG. It is a perspective view which shows one usage example of this embodiment.

  Hereinafter, an auxiliary tool 1 for moving a human body according to an embodiment of the present invention will be described with reference to FIGS. As shown in FIGS. 1 (a) and 1 (b), the auxiliary tool 1 is generally long in the A direction and has a flat plate-like schematic shape extending in both the A direction and the B direction. doing. The A direction and the B direction are orthogonal to each other. In the following, the up-down direction is the up-down direction in FIG. 1A and is a direction orthogonal to the A direction and the B direction. Therefore, the plane direction along both the A direction and the B direction is defined as the horizontal direction. The above definition regarding the direction is made for the convenience of description in the present specification, and is not intended to prescribe the direction when the auxiliary tool 1 is implemented.

  As shown in FIGS. 1 and 2, the auxiliary tool 1 includes a main body 10 having a plate-like schematic shape elongated in the A direction, and a movable sheet 20 wound around the main body 10. . The upper surface of the main body 10 (as will be described later, the upper surface of the fixed sheet 44) forms a mounting surface 10a on which a human body is mounted. The main body 10 includes a mounting plate 30 (corresponding to the inner layer in the present invention), tips 41 and 42, fixing sheets 43 and 44 (corresponding to the surface layer in the present invention), and a bottom plate portion 45 (inventing the present invention). (Corresponding to the support part). Among these, the mounting plate 30, the tips 41 and 42, and the bottom plate part 45 are made of FRP (Fiber Reinforced Plastics). Thereby, the intensity | strength of these members is ensured. In addition, the structure which consists of the mounting board 30 and the fixed sheet | seat 44 respond | corresponds to the human body mounting part in this invention.

  The mounting plate 30 is a plate-like member that is long in the A direction. The upper surface of the mounting plate 30 is formed flat. The mounting plate 30 is formed with a concave portion 30a that opens downward, and as shown in FIG. 3, it has a U-shaped shape in a cross section orthogonal to the A direction. With this configuration, the strength of the mounting plate 30 is ensured. A plurality of projecting portions 31 projecting in a mountain shape downward are formed in the recessed portion 30a. The strength of the entire mounting plate 30 is improved by the increase in the thickness of the mounting plate 30 due to the protrusions 31. A handle portion 32 is provided on one end of the mounting plate 30 in the B direction.

  The tapered portions 41 and 42 have shapes symmetrical to each other with respect to a plane orthogonal to the A direction. In the following, the configuration of the taper 41 will be mainly described, but the taper 42 also has a similar configuration. The tapered portion 41 has a lower surface side inclined with respect to the horizontal direction, and is thereby tapered toward one side along the A direction. The tapered portion 41 has a U-shaped schematic shape including a base portion 41a and two arm portions 41b and 41c as viewed from above. The two arm portions 41 b and 41 c are fixed from the outside to both side end surfaces of the mounting plate 30 in the B direction via a fixture 51.

  As shown in FIG. 2, the fixed sheet 43 is formed by folding both ends in the A direction in a single belt-like sheet in an annular shape and fixing the both ends to the surface of the sheet by sewing or the like. Thus, annular portions 43a and 43b are formed at both ends. In the annular portions 43a and 43b, the base portions 41a and 42a of the tapered portions 41 and 42 penetrate in the B direction. The inner surfaces of the annular portions 43a and 43b are fixed to the surfaces of the tapered portions 41 and 42 by adhesion or the like. A portion of the fixed sheet 43 between the annular portion 43a and the annular portion 43b extends along the A direction in the recess 30a (FIG. 4).

  As shown in FIG. 2, the fixed sheet 44 is composed of one strip-shaped sheet that is endlessly formed by joining both ends in the longitudinal direction. The fixed sheet 44 straddles the upper surface of the mounting plate 30 in the A direction above the mounting plate 30 and covers both end surfaces of the mounting plate 30 in the A direction, and between the mounting plate 30 and the fixed sheet 43 ( 4) The mounting plate 30 is surrounded so as to straddle the recess 30a in the A direction. The fixed sheet 44 is fixed to the upper surface of the mounting plate 30 by adhesion or the like. The upper surface of the fixed sheet 44 forms a placement surface 10a.

  As shown in FIG. 2, the movable sheet 20 is composed of a single belt-like sheet that is endlessly formed by joining both ends in the longitudinal direction. It is preferable that the joint seam is inclined with respect to the B direction. The movable sheet 20 straddles the placement surface 10a in the A direction above the placement surface 10a (the upper surface of the fixed sheet 44), and straddles the recess 30a in the A direction between the fixed sheet 43 and the fixed sheet 44 (FIG. 4). The mounting plate 30 is surrounded outside the fixed sheet 44 so as to cover both end faces of the mounting plate 30 in the A direction. In other words, the moving sheet 20 is wound around the mounting plate 30 and the fixed sheet 44. The movable sheet 20 is not fixed to other members, that is, the fixed sheets 43 and 44, the mounting plate 30, and the like. Therefore, the movable sheet 20 can move around the mounting plate 30 while being in contact with the fixed sheet 43 and the fixed sheet 44 (the mounting surface 10a thereof). Thereby, it is possible to feed the movable sheet 20 from one end to the other end of the mounting plate 30 in the A direction (or from the other end to one end). In addition, when the joint of the moving sheet 20 is inclined with respect to the B direction as described above, when the moving sheet 20 moves around the mounting plate 30, the end of the mounting plate 30 is moved. The joint is less likely to get caught.

  The moving sheet 20 and the fixed sheets 43 and 44 are formed of a material having a relatively small dynamic friction coefficient so that the moving sheet 20 can easily move while being in contact with the fixed sheet 43 and the fixed sheet 44. Preferably it is. It is preferable that at least the dynamic friction coefficient between the moving sheet 20 and the fixed sheet 44 (the mounting surface 10a thereof) is smaller than the dynamic friction coefficient between the moving sheet 20 and the upper surface of the mounting plate 30. Thereby, compared with the case where the fixed sheet 44 is not provided, that is, when the movable sheet 20 is brought into direct contact with the upper surface of the mounting plate 30, the movable sheet 20 is easily moved while being in contact with the fixed sheet 44. In this embodiment, the movable sheet 20 and the fixed sheets 43 and 44 are formed by weaving polyamide-based resin, so-called nylon fibers. Nylon tends to have a small coefficient of friction with other materials such as clothes. The coefficient of friction between nylons tends to be even smaller. The stitches of the nylon fibers are adjusted so that the dynamic friction coefficient in the A direction between the moving sheet 20 and the fixed sheets 43 and 44 is smaller than the dynamic friction coefficient in the B direction. In addition, the stitches of the nylon fiber may be adjusted so that the above-described directionality does not occur in the dynamic friction coefficient between the moving sheet 20 and each of the fixed sheets 43 and 44. Moreover, these may be made of other synthetic resins such as polypropylene, or may be formed from natural materials such as silk. Furthermore, the movable sheet 20 and the fixed sheets 43 and 44 may be formed of different materials.

  The bottom plate portion 45 is a flat plate member and is fixed to the mounting plate 30 from below. Side plates 45 a to 45 d that protrude downward from both ends in the B direction are formed at both ends in the A direction of the bottom plate portion 45. The side plates 45a to 45d are inserted from below between both side surfaces of the mounting plate 30 in the B direction and the two arm portions of the tapered portions 41 and 42. The side plates 45 a to 45 d are fixed to both the mounting plate 30 and the tip 41 or 42 by a fixing tool 51. The bottom plate portion 45 plays a role of supporting the mounting plate 30 from below (from the side opposite to the mounting surface 10a) on the bed or wheelchair when the auxiliary tool 1 is placed on the bed or wheelchair as described later. . Non-slip sheets 46 and 47 are fixed to the lower surfaces of both end portions of the bottom plate portion 45 in the A direction by adhesion or the like. The lower surface of the non-slip sheets 46 and 47 has a larger coefficient of static friction with the surface of the bed or wheelchair than the lower surface of the bottom plate portion 45. At one end of the bottom plate portion 45 in the B direction, semicircular cutouts 45e and 45f are formed as viewed from above. The notches 45e and 45f are arranged at positions where the handle portion 32 is sandwiched between each other in the A direction. The portion of the main body along the horizontal direction in the bottom plate portion 45 is disposed below the movable sheet 20 and the fixed sheets 43 and 44. As shown in FIGS. 1B and 4, a through space 10 b is formed between the main body portion and the mounting plate 30 along the A direction. The movable sheet 20 and the fixed sheets 43 and 44 are disposed so as to pass through the through space 10b along the A direction. The movable plate 20 is restricted by the bottom plate portion 45 from shifting outside the placement plate 30 in the B direction.

  Hereinafter, the usage method of the auxiliary tool 1 is demonstrated, referring FIG. For example, when trying to move the user from the bed 91 to the wheelchair 92, the wheelchair 92 is first placed near the bed 91. Next, the user is seated near the wheelchair 92 at the edge of the bed 91. And the auxiliary tool 1 is arrange | positioned so that the movement sheet | seat 20 may face upwards, and the one end part regarding the A direction of the auxiliary tool 1 is inserted between a user's buttocks and the upper surface of the bed 91. FIG. A tapered portion 42 constituting one end of the auxiliary tool 1 in the A direction is tapered. The tapered portion 42 is covered with an annular portion 43 b of the fixed sheet 44. The fixed sheet 44 is made of nylon that tends to have a small coefficient of friction with other materials. Accordingly, the tapered portion 42 can be easily inserted between the user and the upper surface of the bed 91. Further, the tapered surface 42 has a lower surface facing the bed 91 inclined with respect to the horizontal direction. For this reason, when the user inserts the taper 42 under the collar, the inclined lower surface of the taper 42 follows the upper surface of the bed 91, so that the other end side (the taper 41 side) is higher than the taper 42 side. Stand up to. As a result, the handle portion 32 approaches the user, so that it is easy for the user to insert the taper 42 under the collar while holding the handle portion 32.

  Next, the assisting tool 1 is disposed so as to be bridged between the bed 91 and the wheelchair 92 as shown in FIG. 5 by being tilted along the horizontal direction. Thereby, the lower surface of the one end part in the A direction of the bottom plate part 45 is brought into contact with the upper surface of the bed 91, and the lower surface of the other end part in the A direction of the bottom plate part 45 is brought into contact with the seating surface of the wheelchair 92. At this time, the auxiliary tool 1 can be aligned with respect to the horizontal direction by hooking the notch 45e onto a protrusion or the like on the seating surface of the wheelchair 92. In this state, the bottom plate portion 45 supports the placement plate 30 on the bed 91 and the wheelchair 92. Anti-slip sheets 46 and 47 are provided on the lower surfaces of both end portions of the bottom plate portion 45 in the A direction. For this reason, the auxiliary tool 1 is difficult to slide on the bed 91 and the wheelchair 92. Next, the user moves toward the taper 41 while sitting on the moving sheet 20. The moving sheet 20 and the fixed sheets 43 and 44 are made of nylon. For this reason, these sheets are slippery relative to each other as compared with the slipperiness between the user's clothes and the moving sheet 20. Moreover, the movable sheet | seat 20 can be extended | stretched from the one end of the mounting board 30 regarding the A direction to the other end as above-mentioned. Further, since the dynamic friction coefficient in the A direction between the moving sheet 20 and the fixed sheets 43 and 44 is smaller than the dynamic friction coefficient in the B direction, the moving sheet 20 is smoothly moved in the A direction while suppressing displacement in the B direction. Easy to move to. Therefore, the user can smoothly move to the tip 41 while sliding the movable sheet 20 with respect to the fixed sheets 43 and 44. And when it reaches the taper 41, it changes on the seat surface of the wheelchair 92.

  In addition, when moving from the wheelchair 92 to the bed 91, the operation | work contrary to the above should just be implemented. At this time, the role of each part of the auxiliary tool 1 in the above work is reversed with respect to the A direction. For example, it is not the taper 42 but the taper 41 that is initially inserted between the wheelchair 92 and the user's buttocks.

  According to this embodiment described above, the mounting plate 30, the tapered portions 41 and 42 and the bottom plate portion 45 constituting the main body portion 10 are formed from FRP. Further, the mounting plate 30 is formed in a U shape shown in FIG. As a result, the strength of the entire main body 10 is increased. Therefore, even if the user deposits weight on the main body 10, the main body 10 is not easily bent. Therefore, the user can sit on the auxiliary tool 1 stably. On the other hand, while the user can sit on the assisting device 1 stably, the friction between the user and the assisting device 1 increases as the user puts weight on the assisting device 1, so that the user can move on the assisting device 1. There is a risk that it will be difficult to slip and move. On the other hand, as described above, the auxiliary tool 1 is configured to be able to smoothly move to the tip 41 while sliding the movable sheet 20 with respect to the fixed sheets 43 and 44. For this reason, even if a user sitting on the moving sheet 20 puts weight on the main body 10 through the moving sheet 20, the user moves along the main body 10 while sliding the moving sheet 20 against the fixed sheets 43 and 44. It's easy to do.

  Hereinafter, modifications of the above-described embodiment will be described. For example, in the above-described embodiment, the entire movable sheet 20 is configured to be endless, and is wound around the mounting plate 30 so as to go around the mounting plate 30. Thereby, the movable sheet 20 can be fed from one end to the other end of the mounting plate 30 in the A direction. However, as long as the sheet can be fed from one end to the other end of the mounting plate 30 in the A direction, the sheet may be wound around the mounting plate 30 by other methods. For example, a pair of rollers for winding a sheet is provided so as to sandwich the mounting plate 30 in the A direction, and a belt-like sheet having one end fixed to one of the pair of rollers and the other end fixed to the other is provided. Alternatively, it may be provided so as to extend across the mounting surface 10a. Then, by winding the sheet around one roller and simultaneously feeding the sheet from the other roller, the sheet can be fed from one end to the other end of the placement plate 30 in the A direction while being in contact with the placement surface 10a. Just do it.

  In the above-described embodiment, the fixed sheet 44 is fixed to the placement plate 30 so that the movable sheet 20 is easy to slip. Instead of the fixed sheet 44, the movable sheet 20 may be slippery by coating the upper surface of the mounting plate 30. In this case, the paint layer formed by painting corresponds to the surface layer in the present invention, and the upper surface of the paint layer forms the mounting surface 10a. Such a surface layer may be formed on the upper surface of the mounting plate 30 by a surface treatment other than painting.
