Description

  The present invention relates to simple footwear such as clogs, sandals, slippers, sandals, and the like, and more particularly to a shoe that is designed to be more easily walkable by being formed to be bendable.

  As such a bendable footwear, footwear as described in Patent Documents 1 and 2 is known. FIG. 6 shows a schematic side view of such footwear.

  The footwear X shown in FIG. 7 includes a footrest member 910, a plurality of hard grounding pieces 920 provided on the lower surface of the footrest member 910, and a chin 930 disposed on the upper surface of the footrest member 910. . The footrest member 910 is formed so as to be deformable by an external force. The plurality of grounding pieces 920 are provided in parallel along the front-rear direction on the lower surface of the footrest member 910 with a predetermined interval therebetween. Since the footrest member 910 can be bent, and the plurality of grounding pieces 920 are arranged at a predetermined interval from each other, the footwear X can be bent and deformed upward or downward by an external force. It has become.

  According to the footwear X having the above configuration, when walking on a flat ground or when stepping on a foot, first, the vicinity of the heel touches the ground first, the ground contact surface expands forward, and then the entire sole gradually increases. When touching the ground, and then kicking the ground backwards, the area around the heel first leaves the ground, then from the back to the front of the sole and gradually away from the ground. Since the deformation of the footrest surface corresponding to the deformation can be achieved, the walking feeling is improved and the fatigue is reduced.

  However, since the footwear X can also be deformed into a concave downward, when the footwear X is worn and a step such as a pebble on the ground is stepped on, the footwear X is large so as to be concave downward. It will be deformed. In this case, there is a disadvantage in that the feeling of walking is very bad and the footwear is easy to take off, such as the feeling of discomfort on the soles and the difficulty of kicking the ground by putting force on the soles. In addition, there is a drawback that a great force is applied to the cord and this is likely to break.

  The present invention has been conceived under the circumstances described above, and an object thereof is to provide footwear that can be walked more comfortably.

  The footwear provided by the present invention includes a footrest member having a footrest surface on an upper surface, and a plurality of hard grounding surfaces provided so as to be adjacent to the lower surface of the footrest member in the front-rear direction. The footrest member can be deformed to be concavely concaved upward by an external force, while each of the grounding pieces includes a side surface in the front-rear direction and a grounding surface written on the lower surface, and adjacent to each grounding piece. A contact surface that can contact each other is formed on each side surface that faces the side surface of the grounding piece. When the contact surfaces of the grounding pieces contact each other, The grounding surface is configured to be in the same substantially horizontal plane.

  According to such a configuration, the above-mentioned footwear can be curved to be concaved upward by an external force, and the contact surfaces of the respective grounding pieces are in contact with each other. It cannot be deformed. For this reason, when walking on flat ground with this footwear, it is possible to achieve the deformation of the footrest surface corresponding to the deformation of the sole when walking with bare feet, improving walking feeling and less fatigue Become. Further, even if the footwear is stepped on and the protrusion is stepped on, it does not deform so as to be recessed downward, so that a feeling of strangeness does not occur on the sole, a feeling of walking is kept good, and the footwear is difficult to take off. Therefore, it is possible to walk comfortably even when walking on an uneven road with these footwear.

  In a preferred embodiment, the contact surface formed on the side surface of each grounding piece is formed in at least a partial range of the side surface on which the contact surface is formed. According to such a configuration, since the contact surface may be a part of the side surface of each grounding piece, the width of the shape that can be implemented by each grounding piece is widened, and for example, weight reduction can be realized.

  In a preferred embodiment, the upper surface of the footrest member is covered with a tatami-shaped surface layer material. According to such a configuration, the foot is difficult to slip on the upper surface of the footrest member, and the comfort is further improved.

  In a preferred embodiment, a snare is attached to the footrest surface. According to such a configuration, it can be put on just by pinching the cord between the big toe and forefinger and can be easily taken off. Also, in this case, even if you step on the footwear with this footwear, it will not bend downward, so that there is no sense of incongruity in the sole and excellent walking sensation, and excessive tension may be applied to the nose. There is no such thing as a broken chord.

  Other features and advantages of the present invention will become more apparent from the detailed description given below with reference to the accompanying drawings.

  Hereinafter, a preferred embodiment of the present invention will be specifically described with reference to the drawings.

  FIG. 1 is a perspective view showing a first embodiment of footwear according to the present invention. The footwear A1 shown in FIG. 1 is composed of a footrest member 10, a plurality of grounding pieces 21, 22, 23, 24, 25, 26, and a thong 30. In the following description, the right side in FIG. 1 is the front side of the footwear A1, and the left side is the rear side of the footwear A1. FIG. 2 shows a side view of the footwear A1 when the footwear A1 is worn and standing straight on the flat ground. FIG. 3 shows the state of the footwear A1 walking on the flat ground. 4 is a side view. FIG. 3 shows a state where the user starts landing on the heel and starts stepping on, and FIG. 4 shows a state where the ground is kicked backward with the tip of the toe. In FIGS. 2-4, the foot | leg and the ground are shown with the virtual line. FIG. 5 is a side view showing a state where the user wears the footwear A1 and walks on the stairs.

  The footrest member 10 includes a footrest surface 11 on an upper surface thereof, and includes a rubber layer 12 on a lower surface side. The footrest surface 11 is a surface on which a foot is placed when the footwear A1 is worn, and is covered with bamboo skin knitted in a tatami mat shape. The rubber layer 12 is formed of rubber having a predetermined elasticity, and the footrest member 10 is bonded to the upper surface side thereof. When a predetermined force is applied, the footrest member 10 is concavely curved upward along the front-rear direction as shown in FIG. 3 or FIG. The state of FIG. 2 is restored by the elasticity of the layer 12.

  The grounding pieces 21, 22, 23, 24, 25, and 26 have their upper surfaces continuously adhered to the lower surface side of the rubber layer 12 in order along the front-rear direction, and the grounding surfaces 21 a, 22a, 23a, 24a, 25a, 26a. The grounding pieces 21, 22, 23, 24, 25, and 26 are made of, for example, a hard and lightweight material such as paulownia, and the vicinity of each lower end is attached with rubber. Further, the entire rear side surface of each of the grounding pieces 21, 22, 23, 24, 25 is formed as a contact surface 40 a. Further, a contact surface 40 b facing the contact surface 40 a is formed on the entire front side surface of each of the grounding pieces 22, 23, 24, 25, 26. In the state of FIG. 2, the contact surfaces 40a and 40b facing each other are in contact with each other, and the ground contact surfaces 21a, 22a, 23a, 24a, 25a and 26a are all horizontal to the ground. On the other hand, as shown in FIG. 3 or 4, when the footwear A1 is curved, the contact surfaces 40a and 40b are separated from each other, and the ground contact surfaces 21a, 22a, 23a, 24a, 25a, and 26a are different. Tilt to the direction. Since the ground planes 21a, 22a, 23a, 24a, 25a, and 26a are attached with the rubber, the impact when contacting the floor or the ground can be reduced. If unevenness is formed on the surface of the rubber covering the ground contact surfaces 21a, 22a, 23a, 24a, 25a, and 26a, it is possible to prevent slipping during walking, so that the user can walk more comfortably. In the embodiment shown in FIGS. 1 to 5, on the front side of the grounding surface 21a of the grounding piece 21 located at the foremost side, the gently curved curved portion 21a is retracted upward as it goes forward. 'Is formed.

  The umbilical cord 30 includes a portion that extends vertically near the front end of the footrest member 10 and a portion that extends from this portion toward the left and right ends near the rear end of the footrest member 10. The footwear A1 can be hooked on the foot by sandwiching the portion extending vertically between the thumb and forefinger and hooking the portion extending toward the left and right ends on the instep. Thus, the footwear A1 can be easily put on and taken off simply by hooking the foot on the thong 30.

  Next, the operation of the footwear A1 will be described.

  When walking on a flat ground with such footwear A1, when the foot is stepped on, first, as shown in FIG. 3, the grounding surface 26a of the grounding piece 26 located at the rearmost position first contacts the ground. Subsequently, the ground planes 26a, 25a, 24a, 23a, 22a, and 21a are sequentially grounded so that the ground plane 25a is installed. Next, when kicking the ground backward, the grounding surface 26a of the grounding piece 26 located at the rearmost position first leaves the ground, and finally the grounding surface 21a of the grounding piece 21 located at the foremost position as shown in FIG. Leaves the ground. Therefore, in the footwear A1, the deformation of the footrest surface 11 corresponding to the deformation of the sole when walking with bare feet can be achieved, the walking sensation is improved, and fatigue is reduced. In the embodiment shown in the figure, the smooth convex curved surface 21a 'is formed on the ground contact surface 21a of the foremost ground contact piece 21, so that when the ground is finally kicked by the ground contact surface 21a, it is kicked comfortably. Power can be transmitted to the ground to the end, and walking sensation is improved.

  Further, since the footwear A1 has a structure that does not bend downward from the state shown in FIG. 2, even when the footwear A1 is worn and a step such as a pebble is stepped on, the footrest surface 11 is not deformed. It is hard to remember the sense of incongruity on the back and you can walk comfortably. Moreover, since the footrest surface 11 is not deformed so as to be greatly separated from the sole, the footwear A1 is difficult to take off during walking. Further, since the footrest surface 11 is bent concavely and no excessive tension is applied to the nose 30, the nose 30 is not cut.

  Furthermore, this footwear A1 has a comfortable walking sensation when going up and down stairs. That is, as shown in FIG. 5, when applying the force of stepping on the foot portion on the stairs, the footrest surface 11 is kept substantially horizontal, so there is a risk that the rear portion of the footwear A1 will fall off the stairs. Without being able to act effectively, the force to step on can be applied, and the stairs can be safely climbed. On the contrary, when going down the stairs, even if only the rear part of the foot is on the stairs, the footrest surface 11 is kept horizontal, so there is no danger that the front part of the foot will fall off the stairs, You can safely go down the stairs.

  FIG. 6 shows a side view of a second embodiment of the footwear according to the present invention. The footwear A2 shown in FIG. 6 has the same configuration as the footwear A1 except that the shapes of the grounding pieces 21, 22, 23, 24, 25, and 26 are different. The rear side surface 21b of the ground piece 21, the rear side surface 22c of the ground piece 22, the rear side surface 23c of the ground piece 23, the rear side surface 24c of the ground piece 24, and the rear side surface of the ground piece 25 A contact surface 40a is formed in the lower half of 25c. The contact surface 40b facing the contact surface 40a includes a front side surface 22b of the grounding piece 22, a front side surface 23b of the grounding piece 23, a front side surface 24b of the grounding piece 24, a front side surface 25b of the grounding piece 25, and , Formed on the lower half of the front side surface 26 b of the grounding piece 26. These contact surfaces 40a and 40b protrude forward or backward by a predetermined thickness with respect to the side surfaces 21b, 22b, 22c, 23b, 23c, 24b, 24c, 25b, 25c, and 26b. As shown in FIG. 6, when the contact surfaces 40a and 40b facing each other contact, the ground contact surfaces 21a, 22a, 23a, 24a, 25a, and 26a are all in contact with the horizontal ground. Therefore, the footwear A2 is not bent concavely like the footwear A1. Furthermore, as the grounding pieces 21, 22, 23, 24, 25, and 26, a lighter one having a smaller volume than that of the footwear A1 is used, so the footwear A2 is reduced in weight, and the load on the foot is reduced. It is reduced.

  The positions and sizes of the contact surfaces 40a and 40b on the side surfaces 21b, 22b, 22c, 23b, 23c, 24b, 24c, 25b, 25c, and 26b can be freely modified. For example, the contact surfaces 40a and 40b may be disposed on the upper side or near the center of the side surfaces 21b, 22b, 22c, 23b, 23c, 24b, 24c, 25b, 25c, and 26b.

  The footwear according to the present invention is not limited to the embodiment described above. The specific configuration of each part of the footwear according to the present invention can be varied in design in various ways. For example, the material of the footrest member 10, the grounding pieces 21, 22, 23, 24, 25, 26, and the umbilical cord 30 may be any material used for commercially available footwear, that is, any material. Further, the number and size of the grounding pieces can be changed as appropriate. In the above embodiment, the clogs using the umbilical cord 30 for hooking a foot are shown, but even if it is a band-like thing like a sandal or a footwear like a bag like a slipper, The present invention can be implemented.
