Description

  The present invention relates to a shoehorn that can smoothly put on and take off shoes, and particularly relates to a shoehorn suitable for an elderly person whose function of lower limbs has been reduced or a person with a physical disability.

  2. Description of the Related Art Conventionally, as a tool for assisting the operation of wearing shoes, a long shoehorn used by being placed at a door or a portable short shoehorn has been used. In this type of shoehorn, the shape of the portion to be inserted into the shoe is formed in a spatula shape, and the portion protruding from the shoe is often formed in a rod-like grip or hook.

  When a shoe is worn using a long shoehorn, the heel is applied to the shoehorn standing substantially upward from the heel portion of the shoe, and an unnatural posture with the lower limb greatly bent is forced.

  A healthy person can wear shoes by performing the above-mentioned operation while supporting the body with one foot, but such an operation is impossible for a person with a disability such as paralysis on the half body.

  In view of this, there has also been proposed a shoehorn in which the tip side of the cane is bifurcated, one is a shoehorn shape and the other is a cane (see, for example, Patent Document 1).

  However, a person who remains paralyzed on the half body wears shoes while sitting on a wheelchair or the like, and thus cannot use the above-mentioned cane type shoehorn and is inconvenient to carry.

  Further, as a portable shoehorn, a cashcard-sized shoehorn is known (for example, see Patent Document 2).

  FIG. 7 shows the configuration of the above-described portable shoehorn, and shoulders 50a that can be hooked on the heel portion 51a of the shoe are provided on the left and right sides so that the shoehorn 50 does not slide into the shoe 51 when in use. . In the figure, reference numeral 50b denotes a spatula portion, and 50c denotes a guide portion for guiding the heel into the shoe.

  However, in the portable shoehorn 50 described above, if a heel is placed on the guide portion 50c, it easily falls in the direction of the arrow A, so it is necessary to support the guide portion 50c by hand. Therefore, it is difficult to put on and take off shoes, and it is difficult to use it unless it is a healthy person.

  The present invention has been made in consideration of the problems in the conventional shoehorn as described above. Even if it is a healthy person or a person with a physical disability, it is possible to reliably and smoothly take off shoes. It provides a shoehorn that can be used.

The present invention is a shoehorn comprising a spatula portion and a clip portion provided on the back surface of the spatula portion and sandwiching a shoe heel portion,
The upper portion of the spatula portion is formed to protrude from the shoe and curve backward, and the lower end of the clip portion is longer than the lower end of the spatula portion in a state where the heel portion of the shoe is sandwiched between the clip portions. It is a shoehorn that is formed.

  In the present invention, the clip portion has a width that is substantially the same as the width of the spatula portion, a shoulder portion that is hooked on the upper edge of the heel portion of the shoe, and a width that is narrower than the width of the shoulder portion. It is preferable to have a presser plate part depending from the part.

  In this invention, it is preferable that the said clip part is extended from the height direction approximate center of the said spatula part.

  In this invention, it is preferable that the cross section of the said spatula part in the width direction is formed in the circular arc which becomes convex toward the said clip part side.

  According to the shoehorn of the present invention, even if it is a healthy person or a person with a physical disability, it has an advantage that the shoes can be taken off and put on reliably and smoothly.

It is a perspective view which shows the usage example of the shoehorn of this invention. It is a perspective view which shows another example of use of the shoehorn of this invention. It is a perspective view which shows the structure of the conventional portable shoehorn.

  Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings.

1. 1. Overall configuration of shoehorn In FIG. 1, a shoehorn 1 according to the present invention is mainly composed of a spatula portion 2 which is curved in an arc shape and has elasticity, and a clip portion 3 which is branched from the back surface of the spatula portion 2. The spatula portion 2 and the clip portion 3 are integrally formed of, for example, polypropylene resin, nylon resin, polyethylene resin, polycarbonate resin, or the like.

  In the following description, in the spatula portion 2, the portion to be inserted into the shoe is the lower portion 2a, the portion protruding from the shoe and the portion on which the heel is placed is the upper portion 2b, the surface on which the heel is slid is the front surface, and the opposite surface is the back surface. Call.

  The lower end of the clip part 3 is a free end, and is slightly elastically deformed in the direction of arrow B when attached to the shoe heel part, and the shoehorn 1 is securely fixed to the shoe heel part (not shown) by its restoring force. Can be done.

2. Next, the configuration of each part of the shoehorn 1 will be described with reference to FIGS. 2 and 3.

2.1 Spatula Configuration In FIG. 2, the upper part 2b of the spatula 2 formed in the shape of a tongue having a thickness of 2 mm is large toward the rear so as not to obstruct the shoes when the shoe is taken in and out. It is curved in an arc shape (see FIG. 2C), and is further formed in an arc shape from the center portion 2c of the spatula portion 2 toward the lower portion 2a. In addition, the radius of the upper part 2b formed in circular arc shape can be set in the range of 20-110 mm, Preferably it is 30-100 mm, More preferably, it is 30-90 mm. Note that the radius of the upper part 2b in this embodiment is set to 45 mm.

  When a scissors are placed on the upper part 2b, the scissors can be moved along the front surface of the spatula part 2 while drawing arcs in the order of arrows C1 → C2 → C3.

  On the other hand, a valley fold line 2d (see FIG. 2 (b)) is formed on the front surface of the spatula portion 2 in the center in the width direction, and the spatula portion placed on the upper portion 2b is moved to move the scissors as described above. 2 in the width direction center D (see FIGS. 3A and 3B).

  A string passage hole 2e is provided at the center in the width direction of the upper part 2b so that the string can be passed therethrough. The string passing through the string passing hole 2e is not particularly limited, but if a string having a shape retaining property that extends linearly outward from the shoehorn 1, for example, a string made of polypolopyrene, the shoehorn 1 is removed from the shoe. This is preferable because it saves the trouble of searching for the string.

  The valley fold line 2d extends to the lower part 2a of the spatula part 2, so that the heel can be guided to the center D in the width direction of the spatula part 2 until the operation of putting the foot into the shoe is completed. At the same time, the back surface 2f of the lower portion 2a is adapted to be along the inner surface of the shoe heel portion without any gap.

2.2 Configuration of Clip Part The clip part 3 is made of a band plate formed to a thickness of 2 mm, and is formed in a hook shape downward from the back surface of the central part 2c of the spatula part 2, and the shoulder parts 3a and 3b. And a pressing plate portion 3c.

  The shoulder portions 3a and 3b have substantially the same width as the width of the spatula portion 2 (52 mm in this embodiment), and are hooked on the upper edge of the shoe heel portion.

  The width W of the presser plate portion 3c suspended from the shoulder portions 3a and 3b is narrowed to about 16 mm, and the width of the tip 3d of the presser plate portion is slightly widened.

  A gap E is provided between the back surface 2f of the spatula portion 2 and the presser plate portion 3c to sandwich the heel portion of the shoe, and below the presser plate portion 3c (see F in FIG. 2 (c)). The presser plate portion 3c is curved so as to be convex toward the spatula portion 2 side so that the gap E is minimized.

  Further, a protrusion 3e is formed in the vertical direction on the surface on the spatula portion 2 side of the pressing plate portion 3c, that is, on the pressing side surface. Thereby, the protrusion 3e functions as the pressing portion 3f below the presser plate portion 3c (F portion), and presses the outer side of the heel portion of the shoe by point contact.

  Due to the shoulder portions 3a and 3b and the pressing portion 3f of the pressing plate portion 3c, the clip portion 3 stabilizes the heel portion of the shoe at three points a, b and c (see FIG. 2 (a)). Can be pressed.

  Further, in the state where the shoehorn 1 is mounted on the heel portion of the shoe, the length of the presser plate portion 3c is longer than the lower end of the spatula portion 2 by a length L, in this embodiment, 2 mm to 30 mm. The reason is as follows.

  When a heel is placed on the upper part 2b of the spatula part 2, the upper part 2b of the shoehorn 1 is bent to bend in the direction of the arrow G, so that the length of the presser plate part 3c is the same as the lower end of the spatula part 2 Or, if it is shorter, the shoehorn is easily removed from the shoe.

  On the other hand, in the shoehorn 1 of the present invention, since the length of the presser plate portion 3c is formed longer than the lower end of the spatula portion 2, the reaction force against the force to bend in the arrow G direction side is This reaction force is generated in the H direction, and this reaction force is added to the pressing force of the clip portion 3.

  As a result, the force that presses the heel portion of the shoe is increased, and the shoehorn 1 can be reliably prevented from coming off the shoe.

  The upper limit (30 mm) of the length of the presser plate portion 3c is determined from the length that the presser plate portion 3c does not contact the floor or the ground in a state where the shoehorn 1 is attached to the shoe.

3. 4 shows a state in which the shoehorn 1 having the above configuration is attached to the shoe. FIG. 4 (a) is a front view and FIG. 4 (b) is a side view.

  In both figures, when the gap between the spatula portion 2 and the clip portion 3 in the shoehorn 1 is aligned with the heel portion 10a of the shoe 10, and the spatula portion 2 is inserted into the shoe 10 along the inner surface of the heel portion of the shoe, the clip portion 3 The shoulder portions 3a and 3b are hooked on the upper edge 10b of the heel portion 10a.

  In this state, the pressing portion 3f of the ridge 3e in the clip portion 3 presses the heel portion of the shoe in the arrow J direction, so that the shoehorn 1 is fixed to the heel portion 10a of the shoe 10.

  If a pair of the shoehorns 1 are provided and attached to the left and right shoes, the left and right shoes can be sequentially worn in a standing posture without putting a hand on the shoehorn 1.

4). 4. Usage method of shoehorn 4.1 Use by healthy person FIG. 5 is an explanatory view showing a state where a healthy person is trying to wear a shoe using the shoehorn of the present invention.

  In the shoehorn 1 shown in the figure, the string 11 is passed through the string passing hole 2e.

  Since the upper part 2b of the shoehorn 1 is greatly curved toward the rear, the user can put the toe into the toe part 10c of the shoe 10 and place the heel 20 on the upper part 2b without bending the lower limbs greatly. .

  When the saddle 20 is lowered in this state, the upper part 2b is tilted backward to the limit of 30 °, and the saddle 20 descends while drawing an arc along the arcuate front surface of the spatula part 2, and at this time, the curved upper part Since 2b tries to return to the original posture by the restoring force, a force that pushes the heel toward the toe portion 10c side of the shoe 10 works.

  Accordingly, the foot can be easily slid into the shoe 10 without requiring a large force.

  At this time, since the pressing force in the direction of arrow J is acting on the pressing portion 3f of the clip portion 3 (see FIG. 4B), it is not necessary to support the shoehorn 1 by hand.

  Further, after the shoe 10 is worn, the shoehorn 1 can be easily detached from the shoe 10 by grasping the upper part 2b with fingers or pulling the string 11 with fingers.

4.2 Use by a person with a disability FIG. 6 is an explanatory view showing a state where a person with a disability tries to wear shoes using the shoehorn of the present invention.

  For example, when a shoe is put on a leg with paralysis on the left half of the body, the user usually wears the shoe while sitting on a wheelchair.

  The shoehorn 1 is attached to the heel portion 10a of the shoe 10 in advance.

  Hold the paralyzed left leg with your hand and place it on the right leg.

  Next, the shoe 10 with the shoehorn 1 is brought close to the left leg foot supported by the hand from the lateral direction.

  When the heel is applied to the upper portion 2 b of the shoehorn 1 and the hand is applied to the bottom surface of the shoe 10 and pressed lightly, the heel can be slid into the shoe 10 along the arcuate front surface of the spatula portion 2.

  At this time, since it is not necessary to support the shoehorn 1 by hand, the left hand can easily wear the shoe 10 while supporting the left leg.

  As described above, the shoehorn of the present invention is configured so that the shoes can be smoothly put on and taken off smoothly for the healthy person, for the elderly with impaired leg functions, and for the disabled. Yes.

  Further, since the shoehorn 1 is configured to be extremely compact, it can be carried in a pocket or bag of clothes after being removed. Also, as shown in FIG. 2 (c), the spatula portion 2 and the clip portion. Since 3 becomes independent as a leg, it can also be placed at the entrance or the like as an ornament.

  In addition, since the shoehorn 1 and the shoe can be integrated by sandwiching the heel portion of the shoe with the clip portion 3 of the shoehorn 1, the shoe can be brought close to the feet if it is hung on the upper portion 2e and pulled forward. It can also be used as a tool.

  In the above embodiment, the spatula portion 2 and the clip portion 3 are integrally formed of a synthetic resin. However, the material constituting the shoehorn is not limited to the synthetic resin, and the spatula portion 2 and the clip portion 3 are made of a thin metal material. The shoehorn 1 can also be formed by forming the two and joining them together.

  Alternatively, the spatula portion 2 may be formed of a thin metal plate, the clip portion 3 may be formed of synthetic resin, or vice versa, and both may be joined by in-mold molding or an adhesive.

  In addition, when the spatula part 2 is resin-molded, the spatula part 2 is decorated by performing a so-called simultaneous molding decoration in which a decorative film is simultaneously bonded to the surface of the molded product or a pattern layer of the decorative film is transferred. Since the shoehorn of the present invention is self-supporting, it can also be used as an entrance decoration.
