Description

Technical Field

[0001] The present invention relates to a knee cover for wheelchair users to be worn as rainwear or cold-proof clothing.

Background Art

[0002] Various types of rainwear and cold-proof clothing for wheelchair users are commercially available. One of them is a knee cover. Note that the knee cover is worn as bottoms, and a mantle, poncho, coat, etc. may be worn as tops. While the knee cover can be easily worn simply by placing it on the lower limbs in a simple form, it is likely to shift or roll in the wind. For this reason, the knee cover may be attached to the wheelchair or the user via a strap or the like.

[0003] Patent Document 1 describes that after winding a hanging means composed of a pair of belt-like bodies around the armrests of a wheelchair or handles for movement and engaging a hook to form a closed loop, the slipping off of the main body seat of the knee cover is prevented. Also, Patent Document 2 describes that a fixing means formed of a belt and a hook-and-loop fastener is detachably wound and supported on the armrest portion of a wheelchair to prevent the front body portion of the knee cover from swaying unnecessarily or creating a space for wind and rain to intrude unreasonably. Moreover, Patent Document 3 describes that as a method of fastening a knee-covering lower body cover, snap tapes are attached to both sides of a waist belt and wound around the waist or wound around and fastened to the pipe of a wheelchair.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in addition to having disabled legs, many wheelchair users also have disabled arms. For this reason, it may be difficult to wrap the strap around the waist. In addition, the shapes and arrangements of armrests, pipes, etc. vary depending on the wheelchair. Therefore, even if a strap is attached to an armrest, a pipe, etc., it may not be possible to sufficiently suppress the slipping or winding of the lap belt. The present invention has been made in view of the above problems, and an object thereof is to provide a lap belt that can be used with various types of wheelchairs and is easy for wheelchair users to handle.

Means for Solving the Problems

[0006] The present invention is a lap belt having a main body portion with a front body and a pair of belt-like straps attached to the main body portion, and the above problems are solved by a lap belt in which the straps are rotatably attached to the main body portion at the base ends.

[0007] Since the strap of this lap belt is belt-like and difficult to deform in the width direction, it is easy to handle even for users with disabled arms. Furthermore, since the strap is rotatably attached to the main body portion at the base end, the strap can be attached to the wheelchair user or the components of the wheelchair in various ways. For example, if a pair of straps are arranged to extend in the vertical direction and connected to each other, the strap can be hung around the neck of the wheelchair user. It is also possible to arrange a pair of straps to extend in the horizontal direction and attach the strap to the armrest of the wheelchair. When using a safety belt, it is also possible to arrange a pair of straps to extend in the vertical direction and attach each strap to the safety belt. It is also possible to arrange a pair of straps to extend in the horizontal direction, connect them to each other, and attach the strap to the waist of the wheelchair user. Since the strap can be attached to the wheelchair user or the components of the wheelchair in various ways as described above, it can be used with various types of wheelchairs and is easy for wheelchair users to handle.

[0008] Further, the strap may be detachably and rotatably attached to the main body at the proximal end by a snap button. If the strap is detachably attached to the main body by a snap button, for example, the distal ends of a pair of straps can be connected in advance and looped around the user's neck or waist, and then the proximal end of the strap can be attached to the main body. Also, each strap can be attached to the armrest, pipe, safety belt, etc. of the wheelchair in advance and then the proximal end of the strap can be attached to the main body. In this way, the variations in the attachment methods of the strap increase, which contributes to the facilitation of the attachment of the strap. Also, since the snap button has both a detachable function and a rotation function, it also contributes to the simplification of the configuration.

[0009] The distal ends of the pair of straps may be looped, and a snap button for connecting the two may be provided at the tip of the loop. When connecting the pair of straps and looping them around the user's neck or waist for wearing, if such a snap button is provided, the connection and removal of the pair of straps are easy. Also, if the distal end side of the strap is a loop, it is easy for the user to grip, which contributes to the facilitation of the connection and removal operations of the pair of straps. Furthermore, if a snap button is provided at the tip of the loop, it is preferable because the end of the strap does not extend around from the connection part when the pair of straps are connected. Note that it is also possible for the caregiver to hang the loop on the wheelchair handle and attach the knee rest to the wheelchair.

[0010] Each strap is composed of a proximal strap, an adjuster, a main strap, a first hook-and-loop fastener element, a second hook-and-loop fastener element, and a third hook-and-loop fastener element. The proximal strap is rotatably attached to the main body and connected to the adjuster. The main strap is inserted through the adjuster and its length can be adjusted by adjusting the insertion position. The first hook-and-loop fastener element is installed on the proximal strap, and the second and third hook-and-loop fastener elements are installed at both ends of the main strap. The second hook-and-loop fastener element is detachable from the first hook-and-loop fastener element of the same strap, and the third hook-and-loop fastener element of one strap may be detachable from the third hook-and-loop fastener element of the other strap.

[0011] By providing three hook-and-loop fastener elements on each strap in this way, the attachment methods of the straps can be further diversified. For example, the first and second hook-and-loop fastener elements of each strap can be fastened to attach each strap to an armrest or a safety belt. Also, the third hook-and-loop fastener element of one strap and the third hook-and-loop fastener element of the other strap can be fastened to connect a pair of straps and wrap them around the user's neck or waist for wearing. Further, the straps can be adjusted to a long state with the adjuster and the tip sides of both are connected. After passing the connected straps from the user's neck through the body to the waist, it is also possible to adjust the length of the straps with the adjuster on the front side of the user for easy operation. In addition, it is also possible to connect a pair of straps and wrap them around the backrest of a wheelchair for wearing.

[0012] Also, a strip-shaped core material may be installed along the upper end of the main body, and the proximal end of the strap may be attached to the main body at a position overlapping the core material. If the proximal end of the strap is attached to the main body at a position overlapping the core material, when rotating the strap with respect to the main body, the attachment part of the strap on the main body and its peripheral parts are less likely to be deformed. Therefore, the operation of rotating the strap is easy. Also, it is convenient that the knee rest can be wound around the core material and stored.

[0013] Further, the core material has a main part installed at the upper end of the front body and a pair of extending parts connected to the left and right of the main part, and the pair of extending parts may be bendable with respect to the main part at the left and right ends of the upper end of the front body. When the user of the wheelchair wears the knee rest, by bending the extending part with respect to the main part and arranging it so as to be sandwiched between the user's body and the side guard of the wheelchair, the effect of preventing or suppressing the knee rest from slipping or rolling up can be enhanced. Also, even for a user with a narrow field of vision who has difficulty visually recognizing the lower part, the core material can be guided to an appropriate position on the waist by the feeling of the hand holding the core material, or the extending part of the core material can be guided between the body and the side part of the wheelchair. Further, when storing the knee rest, the extending part of the core material can be bent so as to overlap the main part, and the knee rest can be wound around the main part and the extending part.

[0014] The main body part includes side parts for covering the sides of the lower limbs on the left and right of the front body, and the extending part of the core material may be installed at the upper end of the side part. By the main body part having side parts, the effect of protecting the lower limbs from rain and cold can be enhanced. Also, by the extending part of the core material being installed at the upper end of the side part, when the user of the wheelchair wears the knee rest, by bending the extending part with respect to the main part and arranging it so as to be sandwiched between the user's body and the side guard of the wheelchair, the side part of the main body part is folded so as to cover the side of the lower limb, which contributes to easier wearing.

Advantages of the Invention

[0015] According to the present invention, it is possible to realize a knee rest that can be compatible with various types of wheelchairs and is easy for the user of the wheelchair to attach.

Mode for Carrying Out the Invention

[0017] As shown in FIGS. 1 and 2, the knee rest 10 according to the first embodiment of the present invention includes a main body portion 12 having a front body, and a pair of left and right belt-like straps 14 attached to the main body portion 12. The strap 14 is rotatably attached to the main body portion 12 at the base end. The knee rest 10 can be attached to a wheelchair 16 or a user 18 by the strap 14. FIG. 1 shows a wearing mode in which the knee rest 10 is attached to the user 18 by the strap 14.

[0018] The strap 14 is detachably and rotatably attached to the main body 12 at the proximal end by a snap button 20. The snap button 20 is composed of a first snap 20A and a second snap 20B (see FIGS. 3 and 5). The first snap 20A is an upper snap (convex), and the second snap 20B is a lower snap (concave). Note that the first snap 20A may be a lower snap and the second snap 20B may be an upper snap. As shown in FIG. 3, the strap 14 is configured to include a proximal-end strap 22, an adjuster 24, and a main strap 26. The proximal-end strap 22 and the main strap 26 are belt-like bodies made of materials such as nylon. The material of the snap button 20 is brass, stainless steel, resin, or the like. The proximal-end strap 22 is shorter than the main strap 26, and the first snap 20A is attached to the proximal-end strap 22. The second snap 20B is attached to the upper end of the main body 12 (the end on the waist side of the user 18). Thereby, the proximal-end strap 22 is rotatably attached to the upper end of the main body 12. One end of the proximal-end strap 22 is connected to the adjuster 24. On the other hand, the main strap 26 is inserted through the adjuster 24 in a folded-back manner, and the length of the strap 14 can be adjusted by adjusting the insertion position of the adjuster 24 in the main strap 26.

[0019] In addition, both ends of the main strap 26 are folded back and sewn to form a short loop 30 and a long loop 32. A snap button 28 for connecting a pair of straps 14 is provided at the tip (bent portion) of the long loop 32. As shown in FIG. 4, the snap button 28 is composed of a first snap 28A and a second snap 28B. One of the first snap 28A and the second snap 28B is an upper snap (convex), and the other is a lower snap (concave). Also, the material of the snap button 28 is resin, brass, stainless steel, or the like.

[0020] Each strap 14 is provided with a first surface fastener element 34, a second surface fastener element 36, and a third surface fastener element 38. The first surface fastener element 34 is installed on the surface of the base end strap 22 opposite to the surface where the snap button 20 is attached. The second surface fastener element 36 is installed on the portion of the long loop 38 of the main strap 26. The third surface fastener element 38 is installed on the portion of the short loop 30 of the main strap 26. The first surface fastener element 34 and the third surface fastener element 38 are of approximately the same length. The second surface fastener element 36 is longer than the first surface fastener element 34 and the third surface fastener element 38. The first surface fastener element 34 is a hook, and the second surface fastener element 36 is a loop. Thus, the second surface fastener element 36 is detachable from the first surface fastener element 34 of the same strap 14. Note that the first surface fastener element 34 may be a loop and the second surface fastener element 36 may be a hook. The third surface fastener element 38 of one strap 14 is a hook, and the third surface fastener element 38 of the other strap 14 is a loop. Thus, the third surface fastener element 38 of one strap 14 is detachable from the third surface fastener element 38 of the other strap 14. The third surface fastener element 38 of one strap 14 is installed on the same side as the side where the second surface fastener element 36 of the main strap 26 is installed, and the third surface fastener element 38 of the other strap 14 is installed on the side opposite to the side where the second surface fastener element 36 of the main strap 26 is installed.

[0021] As shown in FIG. 5, the main body portion 12 is configured to include a front body 40, a pair of side portions 42, and a bottom portion 44. The materials of the front body 40, the side portions 42, and the bottom portion 44 are polyester or nylon, and the main body portion 12 as a whole has a flexible texture like cloth. FIG. 5 schematically shows the form of the main body portion 12 when worn. The front body 40 is a substantially rectangular cloth that covers the front surface of the lower limbs of the user 18 of the wheelchair 16. Specifically, the front body 40 has a shape in which the width in the left-right direction gradually and continuously widens slightly from near the central portion in the vertical direction toward the lower end.

[0022] A strip-shaped core material 46 is installed along the upper end of the main body 12. The core material 46 has a main part 48 installed at the upper end of the front body 40 and a pair of extending parts 50 connected to the left and right of the main part 48. At the left and right ends of the upper end of the front body 40, the pair of extending parts 50 can be bent with respect to the main part 48. Note that the extending parts 50 are installed at the upper ends of the side parts 42 (the ends on the waist side of the user 18). Also, the main part 48 is divided at the central part in the left-right direction of the upper end of the front body 40 and can be bent at the dividing part. The second snap 20B of the snap button 20 is installed at a position overlapping the core material 46 (main part 48) in the front body 40. That is, the base end of the strap 14 is attached to the main body 12 at a position overlapping the core material 46. The material of the core material 46 is a resin such as polypropylene.

[0023] Also, as shown in FIG. 2, the front body 40 is provided with a pocket 52. The fabric constituting the front body 40 is folded in a Z shape, and the two overlapping parts on the back side are sewn at the seam 52A to form the pocket 52. The seam 52A does not reach the front-side fabric, and it is configured so that rainwater does not penetrate from the seam 52A. A cover part 54 is provided at the upper opening of the pocket 52. The cover part 54 is also formed by folding the fabric constituting the front body 40 in a Z shape. Hook-and-loop fasteners 56 are installed on the upper part of the pocket 52 and the back surface of the cover part 54, and the opening of the pocket 52 can be held in a closed state. Also, a loop-shaped strap 58 is installed on the cover part 54, and the opening of the pocket 52 can be opened by pinching and pulling the loop-shaped strap 58 with a finger. Also, reflection prints 59 are provided near the vertical center of the left and right peripheral edges of the front body 40.

[0024] The side part 42 is a fabric for covering the side surface of the lower limbs of the user 18 of the wheelchair 16, and is connected to the left and right peripheral edges of the front body part 40 by adhesion and / or sewing. The parts of the connecting part of the side part 42 with the front body part 40 corresponding to above the knee and below the knee are linear with an obtuse angle. The upper end part of the side part 42 is composed of a bag-shaped fabric for accommodating the extending part 50 of the core material 46, and is connected to other parts below this by adhesion and / or sewing. Note that the tip of the fabric for accommodating the extending part 50 protrudes slightly more than other parts of the lower side part 42. The lower end of the side part 42 is connected to the bottom part 44. Also, the opposite side of the connecting part of the side part 42 with the front body part 40 forms an open substantially straight peripheral edge, and a loop-shaped strap 60 is installed near the longitudinal center thereof. Also, a rubber gather is installed in a certain range below the loop-shaped strap 60 on this peripheral edge, and elasticity and stretchability are imparted thereto.

[0025] The bottom part 44 is a substantially rectangular part for covering the toes of the user 18 of the wheelchair 16 from below, and is formed as an extending part of the fabric constituting the front body part 40. Note that the bottom part 44 may be formed by connecting a substantially rectangular fabric to the lower end of the front body part 40 by adhesion and / or sewing. The bottom part 44 forms a bag part that wraps the toes of the user 18 together with the lower part of the front body part 40 and the lower parts of the pair of side parts 42. The opposite side of the boundary of the bottom part 44 with the front body part 40 forms an open substantially straight peripheral edge, and a rubber gather is installed in a certain range near the center in the left-right direction thereof, and elasticity and stretchability are imparted thereto. Also, upper snaps 61A are installed at both left and right ends of the open peripheral edge of the bottom part 44. Also, lower snaps 61B are installed at parts below the knee of the boundary of the side part 42 with the front body part 40. By engaging the upper snaps 61A and the lower snaps 61B, a state in which the bottom part 44 is folded over the back surface of the front body part 40 is maintained, and the vertical length of the main body part 12 is shortened.

[0026] As shown in FIG. 1, the wheelchair 16 is configured to have an armrest 62, a handle 64, a pipe 66, a side guard 68, etc. These parts may be used for mounting the knee rest 10.

[0027] Next, a method of wearing the knee rest 10 of the first embodiment will be described. First, while the user 18 is sitting on the wheelchair 16, the user 18 hangs the main body 12 of the knee rest 10 on his / her lower limbs so that the front body part 40 covers the front surface of the lower limbs. At this time, the bottom part 44 is placed on the toes. Since a rubber gather is installed at the bottom part 44 and elasticity and stretchability are imparted, the bottom part 44 is likely to be placed on the toes. Then, the user 18 bends the extending part 50 of the core material 46 with respect to the main part 48, and arranges the extending part 50 so that the extending part 50 is sandwiched between the body of the user 18 and the side guard 68 of the wheelchair 16. Thereby, the side part 42 of the main body 12 is arranged to cover the side surface of the lower limbs of the user 18. At this time, even if the user 18 pulls up the core material 46 excessively, since the rubber gather is installed at the bottom part 44, the bottom part 44 is not easily detached from the toes.

[0028] Next, the user 18 adjusts the rotational position of the snap button 20 and arranges the pair of straps 14 to extend in the vertical direction. Next, the user 18 connects the tips (bent parts) of the long loops 32 of the respective straps 14 with the snap buttons 28. Thereby, the pair of straps 14 are connected in a loop shape. Next, the user 18 hangs the connected straps 14 around his / her neck. Incidentally, if necessary, the length of each strap 14 is appropriately adjusted by the adjuster 24. Thereby, the wearing of the knee rest 10 is completed. For example, when the wind is strong, the loop-shaped strap 60 and the pipe 66 of the wheelchair 16 may be connected with a strap or the like (not shown).

[0029] Next, the method of folding the knee rest 10 will be described. The user 18 removes the connected strap 14 from around his / her neck and further separates the strap 14 from the main body 12 at the snap button 20. Next, as shown in FIG. 6, the user 18 bends the extending portions 50 with respect to the main portion 48 so that a pair of extending portions 50 overlap the back side of the main portion 48 of the core material 46. The pair of side portions 42 of the main body 12 are also bent so as to overlap the back side of the front body 40. Further, the main body 12 is bent at the central portion in the left-right direction. At this time, the main portion 48 of the core material 46 is bent at the central dividing portion in the left-right direction. In this state, the user 18 winds the main body 12 around the core material 46 (the main portion 48 and the extending portions 50) to make the main body 12 in a compact form. Further, the user 18 accommodates the main body 12 in the compact form in a bag portion formed by the bottom portion 44 together with the lower portion of the front body 40 and the lower portions of the pair of side portions 42. Since a rubber gather is installed on the bottom portion 44 to impart elasticity and stretchability, it is easy to accommodate the main body 12 in the bag portion. Note that another bag or the like may be prepared and the main body 12 in the compact form may be accommodated. Also, the main body 12 may be wound around the core material 46 with the strap 14 attached to the main body 12. In this case, the rotational position of the snap button 20 may be adjusted, and the pair of straps 14 may be arranged along the core material 46 so that the main body 12 is wound around the core material 46.

[0030] As described above, in the first embodiment, since the user 18 hangs the strap 14 around his / her neck and the kneeler 10 is worn, the kneeler 10 can be attached in a stable state regardless of the configuration of the wheelchair 16, and it is possible to prevent or suppress the kneeler 10 from shifting or rolling up. Further, by arranging the extending portion 50 of the core material 46 to be sandwiched between the body of the user 18 and the side guard 68 of the wheelchair 16, the effect of preventing or suppressing the kneeler 10 from shifting or rolling up is enhanced. Also, when the user 18 bends the extending portion 50 of the core material 46 with respect to the main portion 48 and arranges the extending portion 50 so as to be sandwiched between the body of the user 18 and the side guard 68 of the wheelchair 16, the side portion 42 of the main body portion 12 is arranged so as to cover the side surface of the lower limbs of the user 18, so that wearing is easy. Further, even when the field of view of the user 18 is narrow and it is difficult to visually recognize the lower part, the core material 46 can be guided to an appropriate position on the waist by the feeling of the hand holding the core material 46, or the extending portion 50 of the core material 46 can be guided between the body of the user 18 and the side guard 68 of the wheelchair 16. Therefore, wearing is also easy in this respect. Also, since the proximal end of the strap 14 is attached to the main body portion 12 by the snap button 20 at a position overlapping the main portion 48 of the core material 46, when the strap 14 is rotated with respect to the main body portion 12, the attachment portion of the strap 14 and its peripheral portion in the main body portion 12 are not easily deformed. Therefore, the operation of rotating the strap 14 is also easy. Further, since the snap button 28 is installed at the tip of the long loop 32, it is easy for the user 18 to grip, and the connection work of the pair of straps 14 is also easy. Also, since the snap button 28 is installed at the tip of the long loop 32, the end of the strap 14 does not extend around from the connection portion in the state where the pair of straps 14 are connected, which is simple and suitable. Further, by winding the main body portion 12 around the core material 46 (the main portion 48 and the extending portion 50), the main body portion 12 can be easily formed into a compact form, so that the operation of storing the kneeler 10 is also easy. Also, since the compact main body portion 12 can be stored in a bag portion formed by the bottom portion 44 or the like, the operation of storing is also easy in this respect.

[0031] Next, a second embodiment of the present invention will be described. As shown in FIG. 7, in the second embodiment, each strap 14 is attached to the left and right armrests 62 of the wheelchair 16, respectively. Specifically, each strap 14 is wound around the armrest 62, and the second hook-and-loop fastener element 36 is engaged with the first hook-and-loop fastener element 34 to be attached to the armrest 62. The rotational position of the snap button 20 is adjusted so that the pair of straps 14 extends in the left-right direction. Since the other configurations are the same as those in the first embodiment, the same configurations will be denoted by the same reference numerals as in FIGS. 1 to 6, and the description thereof will be omitted. Depending on the shape and arrangement of the armrest 62 of the wheelchair 16 and the body shape of the user 18, attaching the strap 14 to the armrest 62 may sufficiently prevent or suppress the lap 10 from shifting or curling. In such a case, by adjusting the rotational position of the snap button 20 so that the pair of straps 14 extends in the left-right direction, the strap 14 can be easily attached to the armrest 62.

[0032] Next, a third embodiment of the present invention will be described. As shown in FIG. 8, in the third embodiment, the user 18 wears a safety belt 70. The safety belt 70 is worn so as to surround the waist of the user 18 and the backrest of the wheelchair 16. Each strap 14 is attached to the safety belt 70, respectively. Similar to the first embodiment, the rotational position of the snap button 20 is adjusted so that each strap 14 extends in the vertical direction. Each strap 14 is wound around the safety belt 70, and the second hook-and-loop fastener element 36 is engaged with the first hook-and-loop fastener element 34 to be attached to the safety belt 70. Since the other configurations are the same as those in the first embodiment, the same configurations will be denoted by the same reference numerals as in FIGS. 1 to 6, and the description thereof will be omitted. Depending on the shape and mounting position of the safety belt 70 and the body shape of the user 18, attaching the strap 14 to the safety belt 70 may sufficiently prevent or suppress the lap 10 from shifting or curling. In such a case, by adjusting the rotational position of the snap button 20 so that the pair of straps 14 extends in the vertical direction, the strap 14 can be easily attached to the safety belt 70.

[0033] In the first embodiment, the pair of straps 14 are loop-connected by the snap button 28 at the tip of the long loop 32. However, the two straps 14 may be loop-connected by engaging the third surface fastener element 38 of one strap 14 with the third surface fastener element 38 of the other strap 14.

[0034] Also, in the first embodiment, the pair of straps 14 loop-connected are hung on the neck of the user 18. However, as shown in FIG. 9, the pair of straps 14 loop-connected may be wound around the waist of the user 18 and attached. Also, as shown in FIG. 10, the pair of straps 14 loop-connected may be wound around the backrest of the wheelchair 16 and attached. In FIGS. 9 and 10, for convenience, the illustration of the left armrest 62 of the wheelchair 16 is omitted.

[0035] Also, in the second embodiment, the pair of straps 14 are respectively attached to the left and right armrests 62 of the wheelchair 16. However, the pair of straps 14 may be respectively attached to the left and right handles 64 of the wheelchair 16. In this case, as shown in FIG. 11, the short loop 30 or the long loop 32 may be hung on the handle 64 and the strap 14 may be attached to the handle 64.
