Description

[Technical field]

[0001] The present invention relates to a hand and foot protector that is worn on the upper or lower limbs of wheelchair users, such as people requiring care or people with injuries to the upper or lower limbs, when getting in or out of a wheelchair, or to protect the upper or lower limbs during daily life. [Background technology]

[0002] When a wheelchair user gets into or out of a wheelchair, a caregiver or the like generally assists the wheelchair user. When getting into or out of a wheelchair, the wheelchair user's lower legs (the area between the knee and ankle), or the forearms or upper arms (the area corresponding to the upper legs) may collide with the components that make up the wheelchair. This can cause bruises or the like on the wheelchair user's lower legs or upper legs, and the wheelchair user himself or herself is expected to feel considerable pain.

[0003] When getting on and off the wheelchair, it is time-consuming and labor-intensive to assist the wheelchair user without causing the lower or upper limbs to collide with wheelchair components. Therefore, it has been considered to attach a care protector to the lower or upper limbs of the wheelchair user. As an example, Patent Document 1 discloses a care protector that is wrapped around the area between the elbow and wrist or between the knee and ankle of the care recipient, and has a structure including an outer cloth made of a water-impermeable material such as a synthetic resin, a lining cloth made of a sweat-absorbent material that has flexibility and cushioning properties and can absorb sweat from the legs or arms of the care recipient, and an intermediate cloth arranged between the outer cloth and the lining cloth.

[0004] The outer cloth, inner cloth and intermediate cloth are formed into a roughly trapezoidal shape in plan view, and are connected together by quilting so that they do not come apart. The device is wrapped around any part of the cared person's arm or leg that comes into contact with the attachment part of the wheelchair, with the longer side of the upper side of the roughly trapezoidal shape facing upward toward the elbow or knee, and the shorter side of the lower side facing downward toward the wrist or ankle. The device can be put on and taken off by engaging and releasing male and female hook-and-loop fasteners arranged opposite each other on the outer cloth and inner cloth.

[0005] The materials of the outer cloth, inner cloth, and intermediate cloth and the sewing structure of the outer cloth, inner cloth, and intermediate cloth of the nursing care protector are not structured to exhibit elasticity. In addition, the size and installation position of the male and female hook-and-loop fasteners are not structured to correspond to the individual differences in the parts of the body worn by different care recipients. Therefore, when using this nursing care protector, it is necessary to determine and prepare the size according to the size of the part of the body worn by the wearer.

[0006] Next, a cold weather cover for keeping feet warm is shown in Patent Document 2. The cover body of this cold weather cover is composed of a double-layered cloth piece with a water-repellent or waterproof material on the front side and a quilted back side with padding, and the cloth piece itself is configured to be unable to exhibit stretchability. It is described that a stretchable part is formed by attaching a stretchable material to the cloth piece in the circumferential direction, but the specific structure is not disclosed. Therefore, it is unclear whether the cover body can exhibit stretchability. It is also unclear whether this cold weather cover can exhibit a function of protecting the wearer's feet when they collide with some hard object.

[0007] Furthermore, Patent Document 3 shows a foot wrap designed to keep warm that is wrapped around the lower leg over clothing. In this foot wrap, emphasizing the warmth achieved by tightening, it is described that elastic woven fabric is used for the outer and inner layers, but the specific material and structure are not shown. In addition, a pile woven fabric is exemplified as the outer material in the example, but pile woven fabric cannot be said to be a material with elasticity. [Patent Document 1] Patent No. 4009957 [Patent Document 2] Utility Model Registration No. 3057664 [Patent Document 3] Japanese Utility Model Application Publication No. 58-163513 Summary of the Invention [Problem to be solved by the invention]

[0008] The present invention aims to prevent damage and pain to the lower or upper limbs of a person requiring care, by cushioning the impact when a hard object, such as a wheelchair component, collides with the lower or upper limbs of the person requiring care, and to provide a hand and foot protector that can be attached to the lower or upper limbs of a person requiring care with relative ease and that can be attached with an appropriate tightening force to conform to the thickness of the attachment portion of the lower or upper limb. [Means for solving the problem]

[0009] The present invention provides a hand / foot protector comprising a hand / foot protector main body, which comprises a bag body formed by overlapping a substantially rectangular outer cloth and an inner cloth, the outer peripheries of which are sewn together and turned inside out, and an impact absorbing member having a shape that can be stored inside the bag body, and a tie belt for holding the hand / foot protector main body in a state in which it is wrapped around the lower leg or the upper leg, wherein the outer cloth and the inner cloth are made of a stretchable fabric that can stretch in the long side direction of the rectangle of the bag body, the long side of the rectangle of the bag body is longer than the outer periphery of the calf part of the wearer and is long enough to form an overlapping part when the entire lower leg part is covered, the short side of the rectangle of the bag body is long enough to correspond to the height of the lower leg part of the wearer, the tie belt of the hand / foot protector main body is disposed between one long side and the other long side of the bag body, parallel to the long side edge, and each tie belt is disposed between the long side and the other long side of the bag body. the belt is made of a material that is stretchable in its longitudinal direction and has a length that is approximately equal to the length of the long side of the bag body, each of the tie belts is sewn to the surface of the outer cloth of the bag body, integrally with the outer cloth and lining cloth and shock absorbing member that constitute the bag body, one end of the tie belt is attached so as to protrude from the winding end of the hand and foot protection device body, a convex fastener is sewn to the back surface of the protruding part, a concave fastener having a length approximately twice that of the convex fastener is sewn to the surface of the other end of the tie belt, a gap of approximately twice the length of the convex fastener is provided between the convex fastener attachment part and the concave fastener attachment part, and each of the tie belts is positioned at a position shifted inward from the winding start end of the hand and foot protection device body. Effect of the Invention

[0010] According to the present invention, the shock absorbing member made of soft polyurethane foam (hereinafter simply referred to as "urethane") constituting the hand and foot protector body absorbs the shock when the wearer's lower leg or upper leg collides with a component constituting a wheelchair, for example, thereby preventing damage to the part and reducing pain. In addition, the hand and foot protector body and each binding belt are structured to be stretchable in the long side direction of the hand and foot protector, and the binding belt can adjust the tightening force according to the thickness of the lower leg or upper leg when the hand and foot protector body is attached to the lower leg or upper leg, making the attachment work easy. The binding belt itself has elasticity and can be attached following the circumferential length of the attachment part, preventing problems such as falling off. The soft urethane foam is widely used in mattresses, etc., and it is considered that the soft urethane foam with a hardness classification of "hard" or "medium" can be used for this hand and foot protection device. It is also possible to select the hardness of the soft urethane foam appropriately depending on the usage situation of this hand and foot protection device. [Brief description of the drawings]

[0013] An embodiment of the hand and foot protection device of the present invention will be described below with reference to Figs. 1 As shown in Fig. 1 and Fig. 2, the hand and foot protection device is formed in a rectangular shape. The four corners of the rectangle are formed in an arc shape. 1 The bag body that constitutes 10 As shown in Fig. 3, the outer fabric 11 and the lining fabric 12 are sewn together with a sewing machine with a seam allowance of about 1 cm on the outer periphery, and then the outer fabric 11 and the lining fabric 12 are turned inside out and urethane 14 is inserted inside. 10 It is a custom-made product with a rectangular shape that can be stored inside the container, and its thickness is about 1 cm, and it is an example of the shock absorbing member in this embodiment. The urethane 14 used in this embodiment is manufactured by sponge specialty store Softprene Co., Ltd., has a product name of "Soft Urethane Sponge", has a JIS standard density (kg / 35±3) and hardness (N) of 122.6±29.4, and is the second softest product of the company.

[0014] The outer periphery of the turned-inside-out outer fabric 11 and the lining fabric 12 is configured by overlapping and sewing the folded-back portion of the outer fabric 11 and the folded-back portion of the lining fabric 12 together. 10When the bag is turned inside out and the urethane 14 is inserted into the bag, 10 An unstitched section of about 10 cm is formed on a part of the outer circumference, and the unstitched section is used for turning inside out and inserting urethane 14. The unstitched section is sewn by hand to the outer fabric 11 and the lining fabric 12, and then the entire outer circumference is sewn.

[0015] The hand and foot protection device body manufactured in this way 1 An example of the hand and foot protection device is configured to be rectangular as a whole, as shown in Fig. 1 and Fig. 2. 1 The length of the long side is about 48 cm, and the length of the short side is about 24.5 cm. 1 The size of the hand and foot protection device is based on the assumption that the diameter of the wearer's lower leg, consisting of the shin and calf, is approximately 13 cm at maximum. 1 The length of the short side of the hand and foot protection device is designed based on the assumption that the wearer's length from the knee to the ankle is about 24.5 cm. The optimal length of these long and short sides, as well as the dimensions of each part such as the binding belt described below, varies depending on the user's physique, so 1 It is also conceivable that the dimensions of the tie belt can be selected according to the user's physique, such as large size: L, medium size: M, and small size: S.

[0016] Hand and foot protection equipment 1 Includes two tie belts 2 Each of these tie belts is attached. 2 The attachment position of the hand and foot protection device is 1 From the long side edges on both sides towards the inside, 1 The hand and foot protection device is installed at a position equivalent to 1 / 4 of the short side length of the 1 The binding belt is placed at the exact center of the area divided into two parts at the center of the short side direction. 2 Therefore, the hand and foot protection device body 1 The upper and lower halves are tied with their respective binding belts. 2 It can be fixed by:

[0017] Binding Belt 2 is made of a material that is itself stretchable, has a rubber cord built in, and is configured so that when pulled in the longitudinal direction, it stretches and generates a contracting reaction force. 2 The total length of the hand and foot protection device is 1 The length of the long side of the belt is slightly shorter than that of the other belts, at about 46cm. 2 One end 2E of the hand and foot protection device body 1 The end of the belt is attached so that it protrudes about 9 cm from the end 1E of the belt. 2 The other end 2S of the hand and foot protection device body 1 The arm is attached by sewing about 11 cm inside the starting end 1S of the arm. When this 11 cm wide part is wrapped around the thickest part of the lower leg, 1 The winding start end 1S and the winding end end 1E of the belt are overlapped. 2 Hand and foot protection equipment body 1 The outer surface of the outer cloth 11 is sewn together with the outer cloth 11, the urethane 14, and the lining cloth 12.

[0018] Binding Belt 2 The hand and foot protection equipment 1 A convex fastener 21 (for example, a hook-and-loop fastener having an opening hook or the like) is sewn and attached to the back surface of one end 2E protruding from the binding belt. 2 The width of the tie belt is approximately the same as that of the one end 2E, and the length of the tie belt is approximately 9 cm. 2 At the other end 2S of the tie belt, a concave fastener 22 (for example, a hook-and-loop fastener having loops or the like) is attached by sewing to the surface. 2 The concave fastener 22 has a length of about 18 cm, which is twice that of the convex fastener 21. 2The portion where the convex fastener 21 and the concave fastener 22 are attached is configured to be non-stretchable because the convex fastener 21 and the concave fastener 22 are each made of a material that does not stretch. 2 This is the portion between the convex fastener 21 and the concave fastener 22, which is made up only of a tie belt material, and has an elastic structure in a range approximately twice the total length of the convex fastener 21.

[0019] Binding Belt 2 Hand and foot protection equipment 1 The structure of the attachment to the hand and foot protection device will be described with reference to Fig. 4. The hand and foot protection device body is made up of a surface cloth 11, a urethane 14, and a lining cloth 12. 1 , Cable tie 2 The outer fabric 11 is placed on the front surface of the outer fabric 11 and lining fabric 12, and then sewn together by flat stitching using a sewing machine. In this structure, the urethane 14 is depressed by the tightening force during sewing on the front surface sides of the outer fabric 11 and lining fabric 12, forming a recessed portion X at the sewing line. In this structure, the urethane 14 is sandwiched between the upper and lower sewing threads and sewn together by flat stitching as shown in Figure 4, so the sewing threads meander in the thickness direction, and the binding belt 2 And the hand and foot protection equipment 1 The tie belt is configured to be stretchable in its longitudinal direction. 2 And the hand and foot protection equipment 1 Since the tie belt has elasticity in the long side direction and is sewn together by flat stitching, it is possible to form a structure in which both sewn members can stretch in the long side direction. 2 The contraction force of the hand and foot protection device 1 By tightening the outer side with a specified tightening force, the conformability and stability when worn are ensured.

[0020] The following describes how the hand and foot protection device according to the present invention is used by a person requiring care. When the person requiring care is put into a wheelchair, first, the hand and foot protection device is 1 Start wrapping the lower leg from the start end 1S, and overlap the end 1E with the start end 1S. 2The convex fastener 21 at one end 2E of the tie belt is attached to the concave fastener 22 at the other end 2S. 2 The one end 2E of the hand and foot protection device is pulled in its longitudinal direction and tension is applied to the device. 1 The strap can be attached securely to the lower leg or upper leg. 2 One end 2E where the convex fastener 21 is provided is structured to protrude from the hand and foot protection device main body 1, so that the one end 2E can be easily held and attached to the concave fastener 22. That is, compared to the structure in which the hook-and-loop fastener is provided on the back surface of the nursing protector of Patent Document 1, the convex fastener 21 can be attached more reliably to the concave fastener 22, improving workability.

[0021] After putting the hand and foot protection device on the person requiring care, the person is put into a wheelchair. Even if the lower legs or upper limbs of the person requiring care hit components of the wheelchair during the motion of getting into the wheelchair, the hand and foot protection device absorbs the impact, thereby reducing damage and pain to the lower legs or upper limbs of the person requiring care. The hand and foot protection device according to the present invention further comprises a hand and foot protection device main body. 1 Since the length of the long side of the strap is longer than the outer circumference of the wearer's lower leg, the lower leg can be reliably protected. 2 In the hand and foot protection device, an expandable portion consisting of only a tie belt is formed between one end 2E where the convex fastener 21 is attached and the other end 2S where the concave fastener 22 is attached, so that the hand and foot protection device main body 1 can be attached by wrapping it around a thick lower leg or a thin upper leg. 2 The structure is such that the elasticity of the bra itself is ensured and it can be fixed in place by wrapping it around the lower leg or upper leg, etc., of different thicknesses.

[0022] Next, the wearing state of the hand and foot protector according to the present invention will be described with reference to Figs. 5 to 7. Fig. 5 shows only the hand and foot protector in a state where the hand and foot protector is wrapped around the thickest part of the lower leg. Fig. 5(a) is a schematic diagram showing only the binding belt in the hand and foot protector shown in Fig. 5, with the binding belt shown by two lines and the installation part of the convex fastener or concave fastener shown by a thick black line. The outer circumference of the cylindrical part formed by the illustrated hand and foot protector is about 47 cm, the inner circumference is about 40 cm, and the inner diameter is about 13 cm. The axial length is about 24.5 cm. The binding belts installed at the upper middle position and the lower middle position of this hand and foot protector. 2 The fastening state of the convex fastener 21 and the concave fastener 22 is as shown in FIG. 5(a), in which the convex fastener 21 is fastened to the other end 2S side of the concave fastener 22. In this state, the tie belt 2 The circumference of the ring-shaped portion formed by the above is approximately half the circumference of the portion where the convex fastener 21 is attached, the portion where no fastener is provided, and the portion where the concave fastener is attached. The circumference of this ring-shaped portion is ultimately fine-tuned by the degree of overlap of the fastening portions of the convex fastener 21 and the concave fastener 22. Figure 7 shows the hand and foot protector shown in Figure 5 placed on the lower leg of a wearer.

[0023] FIG. 6 shows the hand and foot protection device according to the present invention wrapped around the narrowest part between the elbow and the wrist. In this state, 1 The tubular portion formed by the illustrated hand and foot protection device has an outer circumferential length of about 35 cm, an inner circumferential length of about 19 cm, and an inner diameter of about 6 cm. 2 The fastening state of the convex fastener 21 and the concave fastener 22 is shown in Fig. 6(b) in the same manner as Fig. 5(a), with the convex fastener 21 fastened at a position close to the opposite side of the other end 2S of the concave fastener 22. 2 The circumference of the ring-shaped portion is configured to a length equivalent to the length of the convex fastener 21 and the concave fastener 22. In this way, according to the hand and foot protection device of the present invention, each binding belt2 By changing the fastening positions of the convex fastener 21 and the concave fastener 22 over a wide range by utilizing the parts where no hook-and-loop fasteners are provided, the wrap can be easily attached to correspond to the outer periphery of the object to be wrapped, i.e., the length of the outer periphery.

[0024] The following describes the situation in which the hand and foot protection device according to the present invention is used, and compares it with various commercially available products. When a person requiring care gets into a wheelchair, the device must be worn immediately if necessary. Leg warmers and supporters require the removal of trousers and shoes when putting on and taking off the device, which takes time and increases the burden on the caregiver. In addition, although the person requiring care may be able to put them on and off by themselves, it is assumed that it will take time as well. In addition, since they are in close contact with the skin when lying down, the lower and upper limbs may become sweaty if they are not removed, so it is not recommended to use them regularly. In the case of the hand and foot protection device according to the present invention, it can be worn directly on the lower legs or upper limbs, or even over clothes such as trousers, and can be worn instantly and in a short time without removing shoes or trousers. Furthermore, it is easy to remove.

[0025] People who need nursing care are often physically weak, and are expected to incur many injuries from tripping or falling while moving around, or from bruising, in situations where they are living a normal daily life. By wearing the hand and foot protector according to the present invention as a preventative measure, injuries to the lower legs and upper limbs can be reduced. For people who need nursing care who have difficulty regulating their body temperature, wearing the hand and foot protector according to the present invention can maintain a warming effect even during cold seasons or in rooms where the air conditioner is working well. It has long been said that a cool head and warm feet lead to good health.

[0026] By wearing the hand and foot protection device according to the present invention when a child sits on the rear child seat of a bicycle and gets on and off the bicycle, injuries to the exposed hands and feet of a child who is very active can be prevented. In addition, even children who have difficulty speaking up on their own during cold weather can keep their lower legs and forearms warm while riding. The hand and foot protection device is easy to put on and take off, so it can be used immediately even when you are in a hurry.

[0027] The hand and foot protection device of the present invention can be worn over trousers or thick socks when working outdoors (including sports, etc.) in cold weather, and can be used easily and immediately without removing shoes or trousers, making it suitable for keeping warm. Even when working in an air-conditioned room, such as during office work or other work (night shifts), the device can be removed immediately when not needed, allowing it to be used without worrying about being seen by others.

[0028] By using the hand and foot protection equipment of the present invention when riding a motorcycle, it is possible to easily prevent injuries to the lower legs and upper limbs and keep them warm. However, it is difficult to say that it can prevent injuries in all accidents. Conventional protectors of this type are worn under overalls, so it is necessary to take off boots and pants before putting them on, which takes time to put on and take off, but the hand and foot protection equipment of the present invention can be put on and taken off immediately.
