[First embodiment]
FIGS. 1-22 is a figure which shows the structure of the protective shoes 1 which concern on the 1st Embodiment of this invention. 8 and 9 are views taken along the line VIII in FIG. 1 and are side views of the protective shoe 1. FIGS. 10 and 11 are views taken in the direction of arrow X in FIG. 1 and are side views of the protective shoe 1.

  The protective shoe 1 shown in each figure is a shoe for the left foot, and the protective shoe for the right foot has a form in which the protective shoe 1 shown in each figure is reflected on a flat mirror surface.

  The protective shoe 1 is used in, for example, a transportation company or a factory that uses a carriage, and includes a shoe part 3 and an Achilles tendon protection part (Achilles tendon protector) 5.

  The shoe part (part corresponding to the shoe) 3 is used by a person (operator) to walk with his / her foot in, and is formed in a half-long shoe shape. That is, the shoe part 3 is formed in a semi-long shoe shape with a portion 7 corresponding to a short shoe on the lower side and a cylindrical portion 11 on the upper foot 9 side. Accordingly, when a person puts his / her foot in the shoe part 3 and wears the shoe part 3, the mouth 9 at the upper end of the shoe part 3 is located at the middle part of the person's heel and knee, The part located in the rear of the shaped part 11 covers the Achilles tendon. As long as the Achilles tendon is covered, the shoe part 3 may have another shape such as a boots. In addition, although the skin of the shoe part 3 is comprised with synthetic leather etc., you may be comprised with other materials, such as natural leather.

  The Achilles tendon protection part 5 is configured, for example, by covering a member formed in a “U” shape with leather by bending a plate-like member with a hard synthetic resin such as low-foam polyethylene or low-foam polyurethane. It is located outside the shoe part 3 and behind the shoe part 3. In addition, the Achilles tendon protection part 5 includes a first part 13 (a hard member is not present in this part) that is present on the lower side on one side in the left-right direction. For example, by sewing. Thereby, parts other than the first part 13 are rotatable with respect to the shoe part 3 in a direction approaching or leaving the shoe part 3 around the first part 13.

  Here, the left-right direction in the present embodiment is a direction orthogonal to the paper surface of FIG. 8 and will be described with the front side of the paper surface being left and the back side of the paper surface being right.

  The Achilles tendon protector 5 includes a second part 15 existing below on the other side in the left-right direction, a third part 17 existing above on one side in the left-right direction, and an upper side on the other side in the left-right direction. The fourth portion 19 existing in the shoe is positioned and adjusted so that it can be attached to and detached from a part of the outer surface of the shoe portion 3.

  The shoe part rear part where the Achilles tendon protection part 5 is located behind the shoe part 3 in a state in which the second part 15, the third part 17, and the fourth part 19 are installed in the shoe part 3. Is slightly rotated around the first part 13 and the second part 15 (see arrows in FIGS. 8 and 10).

  Furthermore, in the state where the second part 15, the third part 17, and the fourth part 19 are installed in the shoe part 3, the Achilles tendon protection part 5 has a “U” shape when viewed from above and below. The shoe portion rear portion is covered so as to follow the shoe portion rear portion. In addition, the heel portion, ankle portion, Achilles tendon, calf and the like of the worker are protected from collision / impact of a luggage carrier.

  On the other hand, in a state where the second part 15, the third part 17, and the fourth part 19 are separated from the shoe part 3, the second part 15, the third part 17, and the fourth part 19 may be pivoted about the first part 13 and greatly separated from the shoe part 3. (See FIGS. 6, 7, and 11). However, since the 1st site | part 13 is integrally provided in the shoe part 3, the Achilles tendon protection part 5 does not leave | separate from the shoe part 3, and will become a separate body.

  By the way, the 1st site | part 13 and the 3rd site | part 17 exist in the inner crotch side of the shoe part 3. FIG. Here, the inner crotch side refers to the thumb side instead of the child's toe side when a person wears the protective shoes 1 (shoe part 3). That is, it means the left side for armor shoes for the right foot, and the right side for armor shoes for the left foot.

  Moreover, in the protective shoe 1, the part of the Achilles tendon protection part 5 adjacent to the first part 13 is detachable from the shoe part 3 by a hook-and-loop fastener such as a magic tape (registered trademark) (see FIG. 6, see FIG.

  The protective shoes 1 will be described in more detail.

  The shoe part 3 is provided with a center seam (notch) 21 and a belt-like tongue (sand guard) 23. The center seam 21 has a predetermined width and a predetermined length (height), and is formed above the front side of the shoe part 3. The tongue 23 is provided inside the center seam 21.

  Below the center seam 21, a shoelace 25 for closing the center seam 21 together with the tongue 23 is provided. A toe guard 28 is provided on the toe portion of the shoe portion 3. The toe guard 28 is formed of a material that easily absorbs impact force, such as hard rubber, and includes a large number of convex portions on the surface. And it is integrally provided in the shoe part 3 so that the toe part except the inner crotch side may be covered. By providing the toe guard 28 as described above, the protective shoe 1 can be protected from an impact on the toe portion of the protective shoe 1 when the worker walks. Since the toe guard 28 is not provided on the inner crotch side, the toe guard 28 is less likely to be damaged due to rubbing during walking (rubbing with the other protective shoe).

  The Achilles tendon protection part 5 is formed in a “U” shape as described above, and the portion 13 existing below on one side in the left-right direction is close to the ankle of a person when the shoe part 3 is worn. The shoe part 3 is integrally provided on the outer surface located on the inner crotch side. Thereby, it is rotatable with respect to the shoe part 3. In addition, the site | part 13 is a site | part of the outer surface of the shoe part 3 located near the ankle on the thumb side instead of the child finger side. In other words, the part 13 is a part of the outer surface of the shoe part located near the ankle facing the left foot in the right foot protective shoes, and the right foot in the protective shoes for the left foot. It is the site | part of the outer surface of the shoe part located in the vicinity of the ankle which is facing.

  In addition, a light reflecting material 27 that reflects light is provided on the outer surface (opposite side of the shoe portion 3; rear side) of the Achilles tendon protection portion 5 so that it can be visually recognized when working in a dark environment such as at night. Improve safety and safety.

  The shoe part 3 is integrally provided with a belt-like belt 29. A hook-and-loop fastener engaging portion 31 is provided on the distal end side of the belt 29, and the proximal end portion of the belt 29 is near one edge (edge on the inner crotch side) of the shoe portion 3 adjacent to the center seam 21. It is provided above the outer surface of the shoe part 3.

  A belt engaged portion 33 is provided at an intermediate portion of the belt 29 (an intermediate portion on the tip end side). The engaged portion 33 for the belt is an engaged portion of the hook-and-loop fastener with which the engaging portion 31 of the hook-and-loop fastener of the belt 29 is engaged. Above the outer surface of the tongue 23, a tongue support member 37 through which the belt 29 passes is provided. The tongue support member 37 forms an annular portion through which the belt 29 penetrates in cooperation with the tongue 23, but the annular portion through which the belt 29 penetrates is formed only by the tongue support member 37. May be.

  A first hook-and-loop fastener engaging portion 39 and a second hook-and-loop fastener engaging portion 41 are integrally provided on the surface of the Achilles tendon protection portion 5 on the shoe portion 3 side. The first hook-and-loop fastener engaging portion 39 is provided close to the first portion 13 (provided downward on one side in the left-right direction of the Achilles tendon protection portion 5), and the second hook-and-loop fastener is provided. The engaging part 41 is provided below on the other side in the left-right direction of the Achilles tendon protection part 5.

  Further, the Achilles tendon protection part 5 is provided with a first through hole 43 and a second through hole 45 through which the belt 29 passes. The first through-hole 43 is provided upward on one side in the left-right direction of the Achilles tendon protector 5, and the second through-hole 45 is provided upward on the other side in the left-right direction of the Achilles tendon protector 5. It has been.

  The shoe portion 3 is integrally provided with a first hook-and-loop fastener engaged portion 47 and a second hook-and-loop fastener engaged portion 49. The first hook-and-loop fastener engaged portion 47 is provided on the outer surface of the shoe portion 3 below one side (inner crotch side) of the shoe portion 3 in the left-right direction. The first hook-and-loop fastener engaging portion 39 is engaged. The second hook-and-loop fastener engaged portion 49 is provided on the outer surface of the shoe portion 3 below the other side in the left-right direction of the shoe portion 3 (outer crotch side; opposite to the inner crotch side). A hook-and-loop fastener engaging portion 41 is engaged. Note that the second hook-and-loop fastener engaged portion 49 is located on the outer surface located on the outer crotch side of the shoe portion 3 near the ankle of a person when the shoe portion 3 is worn.

  The first hook-and-loop fastener engaging portion 39 engages with the first hook-and-loop fastener engaged portion 47, and the second hook-and-loop fastener engaging portion 41 engages with the second hook-and-loop fastener engaged portion 49. In this state, the belt 29 passes through the first through-hole 43, the tongue support member 37, and the second through-hole 45, and the hook-and-loop fastener engaging portion 31 at the tip of the belt 29 becomes the engaged portion 33 for the belt. By engaging, the tongue 23 is supported at a position where the center seam 21 is closed without falling or being caught in the shoe portion 3. Further, the Achilles tendon protection part 5 has a “U” shape when viewed from above and below, covers the rear part of the shoe part located behind the shoe part 3 from the outside, and is installed on the shoe part 3. It is like that.

  Here, a case where an operator wears the protective shoes 1 will be described.

  First, as shown in FIGS. 6, 7, and 11, in the protective shoe 1, the Achilles tendon protective part 5 is separated from the shoe part 3, and a person wears the shoe part 3.

  Subsequently, the Achilles tendon protection portion 5 is rotated to engage the engaging portion 39 of the hook-and-loop fastener 22 near the first portion 13 with the engaged portion 47, and the Achilles tendon protection portion 5 is further rotated. Then, the engaging portion 41 of the hook-and-loop fastener is engaged with the engaged portion 49. Thereby, the Achilles tendon protection part 5 comes to almost cover the rear part of the shoe part of the shoe part 3.

  Subsequently, the belt 29 passes through the first through hole 43, the tongue support member 37, and the second through hole 45, and the hook-and-loop fastener engaging portion 31 at the tip of the belt 29 is engaged with the engaged portion 33 for belt. Match. Thereby, the Achilles tendon protection part 5 is firmly supported by the shoe part 3, and the operation | movement (operation | movement which mounts | wears) the protective shoe 1 is complete | finished.

  Note that the way of wearing the protective shoes 1 is not limited to the above procedure, and it is also possible to wear the procedure by simply loosening the belt 29 and tightening the belt 29 after putting the foot in the shoe.

  According to the protective shoe 1, after the worker wears the protective shoe 1, the Achilles tendon protective part 5 is brought into contact with the rear part of the shoe part around the first part 13 provided integrally with the shoe part 3. The second part 15 (for example, the engaging portion 41), the third part 17 (for example, the part corresponding to the first through-hole 43), and the fourth part 19 are rotated to the extent immediately before contact. (For example, the portion corresponding to the second through-hole 45) is installed in the shoe portion 3, and thus it is difficult for the displacement of the mounting of the Achilles tendon protection portion 5 to the shoe portion 3 and the displacement during the operation to occur. . Therefore, the part of the worker's Achilles tendon can be accurately covered with the Achilles tendon protection part 5, and the Achilles tendon can be accurately protected against a collision such as a carriage.

  Moreover, according to the protective shoes 1, since the Achilles tendon protection part 5 is integrated so as not to be separated from the shoe part 3, the Achilles tendon protection part 5 can be prevented from being lost, and the Achilles tendon protection part can be prevented during operation. It is possible to avoid the possibility that 5 falls off the shoe part 3 or the operator's foot and the Achilles tendon protection part 5 is damaged.

  Further, according to the protective shoe 1, when the second part 15, the third part 17, and the fourth part 19 are not installed in the shoe part 3, the Achilles tendon protection part 5 is greatly increased from the shoe part 3. Since it rotates so that it may leave | separate, while it becomes easy for an operator to wear the protective shoes 1, attachment of the Achilles tendon protection part 5 rotates the Achilles tendon protection part 5, and the 2nd site | part 15 and the 3rd site | part Since 17 and the 4th site | part 19 should just be installed in the shoe part 3, mounting | wearing of the Achilles tendon protection part 5 is easy.

  Furthermore, according to the protective shoe 1, even when the second part 15, the third part 17, and the fourth part 19 are installed in the shoe part 3, the first part 13 and the second part 15, the Achilles tendon protector 5 is slightly rotated (the upper side of the Achilles tendon protector is rotated; see the arrows in FIGS. 8 and 10). The resistance of the protective shoe 1 when the person bends the ankle is small, and the worker wearing the protective shoe 1 hardly feels an anomaly in the ankle or the like, making it easy to work.

  Further, according to the protective shoe 1, when the second part 15, the third part 17, and the fourth part 19 are installed in the shoe part 3, the position of the Achilles tendon protection part 5 with respect to the shoe part 3 is finely adjusted. The protective shoes 1 can be used in a manner that matches the shape of the operator's foot.

  Moreover, according to the protective shoe 1, since the 1st site | part 13 exists in the inner crotch side of the shoe part 3, the Achilles tendon protection part 5 will drop | separate and separate from the shoe part 3 by the secular change by use. The situation can be avoided as much as possible. That is, since the inner crotch portion of the protective shoe 1 faces the other protective shoe, it is rubbed in contact with the other protective shoe by an operator's walking or the like. However, in the protective shoe 1, the first portion 13 of the Achilles tendon protective portion provided integrally with the shoe portion 3 is the inner crotch side of the protective shoe 1. And since the 1st site | part 13 is integrally provided by sewing etc., even if the other protective shoes contact, it becomes difficult to damage. Therefore, it is possible to prevent the Achilles tendon protection part 5 from dropping from the shoe part 3 due to secular change due to use as much as possible.

  Furthermore, according to the protective shoe 1, the part (engagement part 41) of the Achilles tendon protection part 5 close to the first part 13 can be attached to and detached from the shoe part 3 by the hook and loop fastener. Before the part 15, the third part 17, and the fourth part 19 are installed in the shoe part 3, the posture of the Achilles tendon protection part 5 with respect to the shoe part 3 can be finely adjusted. Moreover, since the site | part of the Achilles tendon protection part 5 which adjoined the 1st site | part 13 is detachable with respect to the shoe part 3 with a hook_and_loop | surface fastener, in the 1st site | part 13, the Achilles tendon protection part 5 and the shoe part 3 The connection strength can be improved.

  Further, according to the protective shoes 1, the belt 29 is used to support the tongue 23 and the Achilles tendon protection part 5. Therefore, when an operator wears the protection shoes 1, the position of the tongue 23 and the Achilles tendon protection part 5 are supported. The position of the tongue 23 and the Achilles tendon protection part 5 can be easily changed although slightly with respect to the shoe part 3 when the worker wears the protective shoes 1 and works. (See arrows in FIGS. 8 and 10). Accordingly, the fit of the protective shoes 1 is improved, and the operator wearing the protective shoes 1 can easily move the ankles and the like, so that the work can be performed without a sense of incongruity.

  Here, a modified example of the Achilles tendon protection unit 5 will be described.

  FIG. 15 is a diagram showing a form of the Achilles tendon protection unit 5 that has been described above. In addition, the Achilles tendon protection part 5 is formed substantially symmetrically. In FIG. 15, the upper end of the Achilles tendon protection part 5 is positioned slightly below the mouth 9 of the shoe part 3 in the height direction in a state where the Achilles tendon protection part 5 is installed in the shoe part 3. However, the form which is located in the same position as the wear mouth 9 of the shoe part 3 or slightly above the wear mouth 9 may be sufficient. Moreover, the lower end of the Achilles tendon protection part 5 is located at the lower end of the heel cup above the heel (sole part) of the shoe part 3, for example.

  In a state where the operator wears the protective shoes 1, the left and right ankle parts and the rear part of the ankle can be protected by the Achilles tendon protection part 5 and the like. Furthermore, if the upper part of the Achilles tendon protection part 5 is made high by making the shoe part 3 into a boot shape, the upper part of the calf can be protected.

  In FIG. 15, in order to protect the ankle, a triangular portion 51 is provided on the lower side so as to protrude left and right. Further, in order to form the through holes 43 and 45 through which the belt 29 passes, a trapezoidal portion 53 is provided on the upper side so as to protrude left and right. The degree of protrusion is larger in the triangular portion 51. Further, by providing the triangular projecting portion 51 and the trapezoidal projecting portion 53, triangular cutout portions 55 are formed on the left and right sides of the intermediate portion in the height direction.

  FIG. 16 shows the Achilles tendon protector shown in FIG. 15 with the notch 55 removed. By removing the notch 55, the trapezoidal protruding portion disappears, and linear portions 57 extending in the vertical direction are formed on the left and right sides above the Achilles tendon protection portion.

  FIG. 17 shows the Achilles tendon protector shown in FIG. 16 in which a straight portion extending in the vertical direction is shortened and a triangular projecting portion 59 is formed from the lower portion of the through holes 45 and 47.

  FIG. 18 shows an Achilles tendon protection part shown in FIG. 17 in which a straight portion extending in the vertical direction is eliminated and a large triangular projecting portion 61 is formed from above the Achilles tendon protection part.

  FIG. 19 shows that the degree of protrusion of the trapezoidal portion 63 in FIG. 15 is substantially the same as the degree of protrusion of the triangular portion 51. Also in the Achilles tendon protection portion shown in FIG. 19, triangular notches 65 are formed on both the left and right sides of the intermediate portion in the height direction, as shown in FIG.

  FIG. 20 shows the Achilles tendon protector shown in FIG. 19 with the notch 65 removed. FIG. 21 is obtained by deleting the triangular protrusion 51 from the Achilles tendon protector shown in FIG. FIG. 22 shows the Achilles tendon protector shown in FIG. 17 with the triangular protrusion 59 removed.

  Note that the engaging portion 41 and engaged portion 49 of the hook-and-loop fastener and the engaging portion 41 and engaged portion 47 of the hook-and-loop fastener 22 are shown in FIG. 6 and the like from the heel portion toward the upper portion. However, it may be formed in the shape of a triangle as shown in FIG. 12, and may be provided short on the back side of the foot away from the heel.
