Description

  The present invention relates to a shoe for a care recipient that can be easily attached and detached by a care recipient by himself / herself.

  Conventionally, 70% to 80% of people who have a nursing care level of 3 to 4 or more and who are in nursing care facilities have difficulty in putting on and taking off their own shoes. Need.

  However, in care facilities, caregivers are taking care of their caregivers who leave their beds day and night in a bent posture, especially at around 30 caregivers at night. Since care is taken, the movement gives a heavy burden to the caregiver's body and causes back pain.

  As a result, caregivers may suddenly develop low back pain during the care operation and become unable to move, or the back pain gradually becomes worse and even walking becomes difficult, and it takes days for the back pain to recover. This is an important issue not only for facilities and caregivers, but also for those requiring care.

  On the other hand, conventionally, various proposals have been made for elderly people and infants who are difficult to attach and detach footwear such as shoes alone. For example, a shoe with a detachable device described in Patent Document 1 is: Sliding means having a roller on the heel portion of the sole plate laid inside the shoe body, a lift plate portion biased upward by a spring, and a pendulum plate having a weight while being locked at a position where the lift plate portion is pushed down A detachable unit comprising locking means for releasing the lock by using the swing of the sliding means is provided, and when the shoe is worn, the roller of the sliding means is rotated by receiving the heel of the user's foot so that the shoe can be easily You can wear it.

  In addition, when removing the shoes, if the foot wearing the shoes is shaken strongly left and right, the pendulum plate swings left and right around the axis, and the locking means is released by the swing of the pendulum plate. As a result, the upwardly spring-biased lift plate forcibly lifts the user's foot heel so that the shoes can be easily removed from the heel.

  In addition, the shoe described in Patent Document 2 includes a leaf spring having one end attached to the inside of the shoe heel portion, and the leaf spring is separated from the shoe heel portion when the shoe is not used. An inclination is maintained with respect to the portion, and when the shoe is used, as the foot is inserted into the shoe, it approaches the shoe heel portion against the urging force of the leaf spring.

  Further, the leaf spring includes a slide member that is slidable in the vertical direction on the upper surface, and when the shoe is not used, the slide member is moved above the leaf spring, and when the shoe is worn, When inserting the foot into the shoe, the foot is pushed by the heel of the foot and slides over the upper surface of the leaf spring to guide the foot into the shoe, and when removing the shoe, the slide member Moves upward from the leaf spring, and the leaf spring is inclined by the urging force to move away from the shoe heel and push up the heel of the foot.

Japanese Patent Laid-Open No. 140705 Japanese Patent No. 5139966

  The shoe with attachment / detachment device described in Patent Document 1 described above is complicated in structure and has a large number of parts, so that there is a problem that the manufacturing cost is high, and swinging of the pendulum plate is used for the heel portion of the shoe body. Since the lock means having a complicated structure for unlocking the raised plate portion is incorporated, there is a possibility that the function of the lock means may be hindered when foreign matters such as sand and pebbles enter the shoe.

  In addition, when taking off shoes, it is structured to release the lock of the raised plate part by shaking the foot wearing the shoe left and right, so depending on the care recipient who has difficulty walking, unlocking by moving the foot left and right In addition, there is a possibility that the lock is inadvertently released when the side of the shoe is hit against something during walking and an impact is applied to the pendulum plate.

  Further, since the shoe described in Patent Document 2 does not have a structure for fixing the leaf spring or the slide member when worn, when the heel of the foot is lifted from the shoe during walking or the like, the leaf spring is attached. There was a risk that the shoes would be inadvertently removed due to the force.

  Therefore, the present invention eliminates the problems of the prior art as described above, and there is no risk of inadvertent removal during walking, and the care recipient can easily perform the attaching / detaching operation of the shoes by himself / herself. An object of the present invention is to provide a safe and reliable shoe for care recipients, which has a simple structure and can be manufactured at low cost.

  The shoe for the care recipient of the present invention provided for the above-mentioned purpose is provided with a bottom plate fixed to the upper surface of the bottom portion inside the upper portion with the longitudinal direction in the front-rear direction of the shoe, and the upper portion from the rear end of the bottom plate. A flange receiving plate that is integrally connected to the bottom plate so as to rise along the inner surface of the flange portion, and has a rectangular slit hole that is elongated vertically in the center in the width direction, and the upper end is It is connected to the flange receiving plate at the upper end of the slit hole, and is provided so as to be elastically displaceable in the front-rear direction within the slit hole, and the lower end portion and the central portion in the vertical direction always protrude forward by a predetermined amount from the flange receiving plate. The front and rear end of the bottom tongue plate has a habit and the front end portion is joined to the upper surface of the front end portion of the bottom plate, the rear end side warps from the upper surface of the bottom plate, and the rear end is close to the front surface of the base plate. Up and down along this at the position It is provided so that it can be displaced in the direction, and has an insole holding plate that holds the lower surface of the insole of the shoe. When the shoe is not worn, the back end of the heel support plate rises near the upper end of the heel support plate due to its elasticity When wearing shoes, if you press down the insole holding plate by stepping on the insole with your foot, the rear end of the insole holding plate engages the lower end of the locking tongue piece and comes close to the upper surface of the bottom plate When the shoe is taken off and the shoe is taken off, the bottom end of the shoe tongue and the insole holding plate The engagement between the ends is released, and the rear portion of the insole is pushed up to a position near the upper end of the collar portion of the upper portion by the elasticity of the insole holding plate.

  In the shoe for the care recipient of the present invention, the rear end side of the insole holding plate is provided between the bottom plate and the insole holding plate, and the rear end side of the insole holding plate approaches the upper surface of the bottom plate. It is desirable to provide a leaf spring having a substantially bow shape when viewed from the side, which has a characteristic that the urging force rapidly decreases.

  According to the shoe for care recipients according to the invention described in claim 1, since the number of parts is small and the structure is simple, high reliability and durability can be obtained, and the manufacturing cost can be reduced.

  In addition, when wearing shoes, the insole holding plate that tilts forward and the rear end side is raised can smoothly guide the foot into the upper part of the shoe. Caregivers can easily wear shoes on their own.

  And when using shoes, the back end of the insole holding plate is securely locked by the lower end of the locking tongue provided on the heel support plate, so that in the normal walking motion, the insole holding There is no possibility that the shoes will be inadvertently detached due to the engagement between the plate and the locking tongue piece, and it is possible to walk safely.

  According to the shoe for the care recipient according to the invention described in claim 2, in addition to the effect of the invention of claim 1, the urging force is further increased as the rear end side of the insole holding plate approaches the upper surface of the bottom plate. Since the elastic biasing force of the insole holding plate is assisted by an auxiliary plate spring with a substantially bow-shaped side view that has a sharply decreasing characteristic, a thin plate can be used for the insole holding plate, and when wearing shoes In the middle of sliding the toe of the foot into the upper part, the insole holding plate is not pushed down by the sole of the foot, and the foot can be easily inserted into the upper part.

  In addition, when the rear end of the insole holding plate is lowered to the engagement position with the locking tongue, the auxiliary leaf spring extends in the front-rear direction and the urging force decreases rapidly. Can be locked, and the burden on the locking tongue can be reduced. As a result, mutual wear due to repeated engagement and disengagement operations between the insole holding plate and the locking tongue piece is reduced, and durability can be enhanced.

  As shown in FIGS. 1 to 3, a hook receiving plate 4 </ b> B that rises along the inner surface of the flange 3 </ b> B of the upper portion 3 is integrally connected to the rear end of the bottom plate 4 </ b> A. The flange receiving plate 4B is formed in a gently curved shape that swells rearward along the curved shape of the inner surface of the flange 3B.

  In addition, a fold receiving portion 3C is formed on the upper end of the heel portion 3B of the upper portion 3 so that the upper edge of the heel receiving plate 4B directly hits the heel of the foot and is not injured. The upper end of 4B is covered.

  As shown in FIG. 4, a rectangular slit hole S that is elongated in the vertical direction is formed at the center in the width direction of the collar receiving plate 4B. Inside the slit hole S, there is provided a leaf spring-like locking tongue piece 4C which is elongated in the vertical direction.

  The upper end of the locking tongue piece 4C is integrally connected to the flange receiving plate 4B at the upper end of the slit hole S, and is provided in the slit hole S so as to be swingable in the front-rear direction by elastic deformation. Further, the locking tongue piece 4C is curved so that the lower end portion and the central portion in the vertical direction protrude forward, and these portions always have an elastic behavior in which a predetermined amount protrudes forward from the hook receiving plate 4B. Have.

  In the present embodiment, the bottom plate 4A, the flange receiving plate 4B, and the locking tongue piece 4C are integrally formed from a single stainless steel plate for leaf springs. A thinned hole h that is elongated in the vertical direction is provided at the center in the width direction so that it can be elastically deformed flexibly.

  The insole push-up mechanism 4 includes an insole holding plate 4D and an auxiliary leaf spring 4E. The insole holding plate 4D is made of a stainless steel plate for a leaf spring having substantially the same width as the bottom plate 4A, and its front end portion is folded back to the lower surface side to form a folded portion a having a predetermined length.

  As shown in FIG. 5, the folded portion a has a lower surface integrally joined to the bottom plate 4A by spot welding at four positions on the upper surface of the front end portion of the bottom plate 4A. For joining between the insole holding plate 4D and the bottom plate 4A, other joining means such as rivet joining may be used instead of spot welding.

  Further, instead of forming the folded portion a, a rectangular plate having the same size as the folded portion a is sandwiched between the upper surface of the front end portion of the bottom plate 4A and the lower surface of the front end portion of the insole holding plate 4D as a spacer. You may make it join 4A and the insole holding | maintenance board 4D.

  The insole holding plate 4D has an elastic behavior in which the rear end side warps with respect to the upper surface of the bottom plate 4A, and the rear end can be displaced vertically along the front surface of the collar receiving plate 4B. Is provided.

Further, the auxiliary leaf spring 4E is formed so that the central portion in the longitudinal direction is curved downward in a substantially arcuate shape when viewed from the side, and the rear end portion thereof is in the central portion in the width direction in the vicinity of the rear lower end of the insole holding plate 4D. It is fixed by spot welding with the insole holding plate 4D aligned in the longitudinal direction.
The auxiliary plate spring 4E may be fixed to the insole holding plate 4E by using known fixing means such as rivet bonding instead of spot welding.

  Further, the front end of the auxiliary leaf spring 4E is a free end, and is slidable in the front-rear direction along the lower surface of the insole holding plate 4D. The auxiliary plate spring 4E is made of spring steel that can be deformed greatly, and is formed thinner than the insole holding plate 4D.

  As shown in FIGS. 1 and 2, the insole 5 is composed of an upper insole 5A and a lower insole 5B. The upper insole 5A is made of a synthetic leather or a resin material that is thin and flexibly bent. It can be removed from the shoe 1 for cleaning or replacement.

  On the other hand, the lower insole 5B is formed of a thick material having flexibility and elasticity such as urethane rubber, and is fixed to the upper surface of the insole holding plate 4D with an adhesive or the like. The gap between the inner surface of the front end portion of the portion 3 and the front end portion of the insole holding plate 4D is covered so as not to cause a step.

  When wearing the shoes 1 for care recipients configured as described above, as shown in FIG. 2, the insole holding plate 4D of the insole push-up mechanism 4 with a load acting from the heel of the foot F through the insole 5 is provided. The rear end side is pushed down to a lower position against an upward biasing force in which the elasticity of itself and the elasticity of the auxiliary leaf spring 4E are combined.

  In this state, as shown in FIGS. 2 and 6, the rear end of the insole holding plate 4D is positioned below the lower end of the locking tongue piece 4C, and the lower end of the locking tongue piece 4C is the insole holding plate 4D. Is engaged with the rear end portion of the upper surface of the inner support plate 4D to prevent the insole holding plate 4D from moving upward.

  As shown in FIG. 2, the rear ends of the upper insole 5A and the lower insole 5B constituting the insole 5 are positioned slightly forward of the rear end of the insole holding plate 4D, and the locking tongue piece 4C is engaged. The upper surface of the rear end portion of the mating insole holding plate 4D is exposed so as not to contact the lower end of the locking tongue piece 4C.

  Next, a procedure for wearing the nursing care shoe 1 configured as described above will be described with reference to FIG. When the shoe 1 is worn, as shown in FIG. 3A, the shoe 1 at the position where the rear end of the insole 5 is raised is placed on a horizontal floor G or the like, and is along the upper surface of the insole 5. Then, the foot F is slid into the upper portion 3 from the toe side, and the entire sole is placed on the insole 5 as shown in FIG.

  In this process, the auxiliary leaf spring 4E disposed below the insole holding plate 4D supports the insole holding plate 4D from below with an arcuate shape, so that it is elastically deformed even if a relatively large load is applied. It is difficult to insert the foot F easily because the insole 5 is held in a forward tilted posture.

  Next, as shown in FIG. 3C, when the weight applied to the heel of the foot F is stepped on and the load acting on the auxiliary leaf spring 4E exceeds a predetermined magnitude, bending deformation occurs, and the insole holding plate 4D The rear end side is displaced downward together with the insole 5. At this time, the urging force of the auxiliary leaf spring 4E rapidly decreases as the rear end side of the insole holding plate 4D approaches the upper surface of the bottom plate 4A, and its front end is guided forward by the lower surface of the insole holding plate 4D. Extend.

  At this time, the auxiliary leaf spring 4E is provided between the lower surface of the insole holding plate 4D and the upper surface of the bottom plate 4A by providing the folded portion a (see FIG. 4) at the front end portion of the insole holding plate 4D as described above. Since the clearance more than this thickness is ensured, the auxiliary leaf | plate spring 4E can perform an extending | stretching operation | movement without hindrance.

  Further, the rear end of the insole holding plate 4D slides the locking tongue piece 4C against the elastic biasing force while sliding the front surface of the lower end of the locking tongue piece 4C provided on the collar receiving plate 4B. As shown in FIG. 4D, the engaging tongue piece 4C moves to a position below the lower end thereof.

  Then, the engagement body 4C moves forward and returns due to its elasticity, and locks the insole holding plate 4D at a position close to the upper surface of the bottom plate 4A. In this state, since the foot F is completely held in the upper portion 3, a normal walking motion similar to that of ordinary shoes is possible.

Next, a procedure for taking off the shoes for care recipient 1 will be described with reference to FIG.
When the shoe 1 is taken off, as shown in FIG. 2A, the rear end of the shoe sole 2 is lightly hit against the floor G or the like with the toe side facing up.

  If it does so, since the center part b of the up-down direction of the latching tongue piece 4C which protrudes ahead from the collar receiving plate 4B will be pushed by the heel of the foot F, the lower end of the said latching tongue piece 4C will resist the elastic biasing force. Then, it retracts and the engagement with the upper surface of the rear end of the insole holding plate 4D is released.

  The insole holding plate 4D itself has an elastic property that the rear end side warps upward, and is always urged upward by the auxiliary leaf spring 4E incorporated below the insole holding plate 4D. When the engagement with the piece 4C is released, the rear end side of the insole holding plate 4D is displaced upward with the insole 5 as shown in FIG. 5B, and the heel side of the foot F is pushed out from the upper portion 3. .

  Therefore, the shoe 1 can be easily taken off by putting the entire shoe sole 2 on the floor G and extracting the toe side of the foot F backward from the upper portion 3. At this time, as the rear end side of the insole holding plate 4D is displaced upward, the auxiliary plate spring 4E is restored to a side-view arcuate shape by its elasticity and its urging force increases. Therefore, when the foot F is extracted, the insole holding plate The rear end side of 4D will not fall carelessly.

In the present embodiment, the insole push-up mechanism is configured by incorporating the auxiliary leaf spring 4E between the bottom plate 4A and the insole holding plate 4D, but the elastic biasing force of the insole holding plate 4D itself is large. In this case, the attaching / detaching operation of the shoe 1 is possible without providing the auxiliary leaf spring 4E.
In this case, it is possible to directly join the upper surface of the bottom plate 4A without forming the folded portion a (see FIG. 1 or 4) at the front end portion of the insole holding plate 4D.

  Further, here, the auxiliary leaf spring 4E has a shape in which the central portion in the longitudinal direction is bent downward in a substantially arcuate shape in a side view, and its rear end is fixed to the lower surface of the insole holding plate 4D. The auxiliary leaf spring has a shape in which the central portion in the longitudinal direction is curved in a substantially arcuate shape when viewed from the side, and the curved portion abuts against the lower surface of the insole holding plate to urge the auxiliary leaf spring. It is also possible to use what is fixed to the upper surface of the bottom plate.

  Moreover, in the thing of embodiment mentioned above, although the bottom part 3A of the shoe sole part 2 and the upper part 3 is manufactured with another material, a bottom part is integrated with a shoe sole part, without providing a bottom part in an upper part. Also good.

  In addition, the insole 5 is composed of two upper insole 5A and a lower insole 5B fixed to the upper surface of the insole holding plate 4D, but the shoe for the care recipient of the present invention is insole. However, the structure is not limited to this, as long as it is held at least on the upper surface of the insole holding plate and can receive the entire sole.

  Further, on the front surface of the locking tongue 4C that directly touches the heel of the foot, a flexible short fiber such as polyamide is used by using means such as electrostatic flocking, except for a portion near the lower end that comes into contact with the rear end of the insole holding plate 4D. You may make it coat | cover with resin with slipperiness | lubricity.

  The shoes for care recipients of the present invention are particularly useful in facilities and hospitals that accommodate a large number of elderly people who need assistance for taking off shoes, and there are elderly people and other care recipients. It can also be used in ordinary households.
