Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an anti-slip device for shoes to prevent falling when walking on an icy snowy road or a snowy road surface.

(Prior Art) As shown in FIG. 4, a conventional anti-slip device for shoes includes a recess (C) that communicates with the arch of the foot (C) in the heel (B) of a rubber sole (A), and a distal end (C) in the recess (C). Both sides of the proximal end of the spike metal fitting E, which has claws D formed on the sides, are supported by the spike support metal fitting G, and it is mounted rotatably, and when in use, the claws at the tip protrude from the ground surface of the heel part B, as shown in the figure. When not in use, the spike fittings are rotated in the direction of the arrow so that the claw at the tip is positioned at the arch of the shoe.

(Problem to be solved by the invention) However, in the above-mentioned conventional shoe anti-slip device, when the spike fitting is rotated, the rear end of the spike fitting directly presses against the concave surface of the heel while rotating. As the spike fittings move, the pressing sliding surface is significantly worn, and as a result, the spike fittings no longer rotate smoothly, and it is difficult to maintain the spike fittings stably in the used and unused states over a long period of time. This has the drawback that the metal spike fittings become loose within a short period of time and cause rattling, and since the spike fittings are made of metal, the rattling causes noise when walking.

Further, since the tip of the spike metal fitting is located at the arch of the foot when not in use, there is a problem when an object comes into contact with the arch of the foot.

The present invention was developed with an eye to the above-mentioned problems.It prevents wear, ensures smooth rotation over a long period of time, and allows a member corresponding to a spike fitting to protrude from the arch of the foot. To provide an anti-slip device for shoes which rotates without any slippage and ensures stable retention when used as an anti-slip device and stable retention when not in use.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides an anti-slip device for shoes with two pressing projections on the top and bottom of the rear end of the arm 1.
and a pivot 3 in the left and right horizontal direction of the rear end.
A spike body 6 made of a hard and tough thermoplastic synthetic resin is integrally formed with a head 5 having a protruding spike rivet 4 planted on one side of the tip;
A shoe sole 9 having a rubber heel portion 8 provided with a recess 7 forming a used state storage recess 18 in which the spike body 6 is stored when in use and an unused state storage recess 19 in which the spike body 6 is stored when not in use. , a spike support member 10 that pivots the pivot 3 of the spike body 6 and is fixed within the recess 7 of the sole 9; and between the spike support member 10 and the inner surface of the recess of the sole 9. The plate 11 is made of a hard thermoplastic synthetic resin and has a groove 17 corresponding to the pressing edge 2 of the spike body 6.

(Function) When the above-mentioned anti-slip device for shoes of the present invention is used, when walking on an icy or snow-covered road surface, that is, when in use, the spike body 6 is placed in such a state that the spike studs 4 of the head 5 protrude from the sole 9. When not in use, the spike body 6 is rotated about its pivot 3 and stored in the concave part 7 together with the spike stud 4 for use.

In this case, when the spike body 6 is in use or not in use, the pressing ridge 2 formed at the rear end of the arm 1 is connected to the hard thermoplastic synthetic resin plate 11.
The rubber constituting the heel portion 8 is pressed through the heel portion 8, thereby preventing sliding wear on the rubber surface. The pressing ridge 2, which is further displaced, presses the rubber of the heel portion 8 through the plate 11, and the groove 17 does not come into sliding contact with the rubber.
, so that the tip of the spike body 6 is always pressed against the bottom surface of the recess 18 for storing the spike body 6 when in use, and when the spike body 6 is not in use, the pivot 3 at the rear end of the spike body 6
The pressing protrusion strip 2, which is further displaced, presses the rubber of the heel portion 8 via the plate 11 and fits into the groove 17 without slidingly contacting the rubber, preventing the spike body 6 from being inadvertently raised and not being used. The condition will be maintained stably.

(Embodiment) An embodiment of the present invention will be described in detail below with reference to the drawings.

Figure 1 is an exploded perspective view of the anti-slip device for shoes.
FIG. 2 is a bottom view showing the heel portion of the sole, and FIG. 3 is a sectional view taken along line A--A in FIG. 2.

The anti-slip device for shoes shown in these figures is composed of a spike body 6, a sole 9, a spike body support member 10, and a plate 11.

The spike body 6 is made of a hard and tough thermoplastic synthetic resin such as polyacetal, and has a pressing ridge 2 formed above and below the rear end of the arm 1 having a rectangular cross section. A pivot 3 is provided horizontally protruding from the rear end which is slightly displaced in the direction, and a head 5 and an operating protrusion 12 are integrally formed at the tip end with a spike stud 4 implanted on one side. This is the configuration.

The spike body support member 10 supports the spike body 6.
The bearing part 14, in which the pivot part 13 supporting the pivot shaft 3 faces each other, and the fixing part 16 in which the fixing hole 15 is formed are integrally formed.

The plate 11 is made of the same material as the spike body 6, and is provided with two grooves 17 corresponding to the pressing edges 2 of the spike body 6.

The sole 9 has a heel portion 8 made of rubber, and the heel portion 8 includes a recess 18 for storing the spike body 6 in a used state, a recess 19 for storing the spike body support member in an unused state, and a recess for fixing the spike body support member. 20 are arranged in series.

A blind hole 21 into which the spike rivet 4 is inserted is provided at the bottom of the recess 19 for storage when not in use.
On the bottom surface of the spike body support member fixing recess 20,
Fixing hole 1 of fixing part 16 of spike body support part 10
A through hole 22 is provided corresponding to 5.

Each part of the above configuration includes inserting and supporting the pivot shaft 3 of the spike body 6 into the pivot part 13 of the bearing part 14, and disposing the plate 11 on the bottom surface of the spike body support member fixing recess 20 on the lower surface of the bearing part 14. Then, it is assembled by passing the screw 23 and the through hole 22 through the fixing hole 15 of the spike body support part 10 and fixing it to the stopper 24.

When walking on an icy snowy road or a snowy road surface, that is, when using the shoe, as shown in FIGS. The heel part 8 is housed and held in the recess 7 of the heel part 8 in a sideways state so as to protrude from the part 8.

At this time, the pressing ridge 2 displaced from the pivot 3 at the rear end of the spike body 6 presses the rubber of the heel portion 8 via the plate 11 and fits into the groove 17 without slidingly contacting the rubber. The tip of the spike body 6 always presses against the bottom surface of the recess 18 for storing the used state, thereby preventing inadvertent standing up and stably maintaining the used state.

When not in use, insert a fingertip or the like into the recess 18 for storing the used state and hang it on the operation protrusion 12 at the tip of the spike body 6, so that the spike body 6 can be moved to its pivot point 3.
is rotated about the center of rotation, and the spike rivet 4 is stored in the recess 19 for storing the unused state so that it enters the blind hole 21.

In this case as well, the pressing protrusion 2 displaced from the pivot 3 at the rear end of the spike body 6 presses the rubber of the heel part 8 via the plate 11, similar to when the spike body 6 is in use. The spike body 6 is fitted into the groove 17 without slidingly contacting the rubber, thereby preventing the spike body 6 from inadvertently standing up and stably maintaining the unused state.

(Effect of the invention) According to the anti-slip device for shoes of the present invention constructed and operated as described above, when the spike body 6 is in the used state and the non-used state, the pressing protrusion formed at the rear end of the arm 1 is used. The edge 2 presses against the rubber constituting the heel portion 8 through the hard thermoplastic synthetic resin plate 11, preventing sliding wear on the rubber surface and thereby preventing the use of the spike body 6. In this state, the pressing protrusion 2 displaced from the pivot 3 at the rear end of the spike body 6 presses the rubber of the heel portion 8 via the plate 11 and fits into the groove 17 without slidingly contacting the rubber. The tip of the spike body 6 always presses against the bottom of the storage recess 18 when in use, and when the spike body 6 is not in use, the pressing ridge 2 displaced from the pivot 3 at the rear end of the spike body 6 presses against the plate. When the rubber of the heel portion 8 is pressed through the heel portion 11, the spike body 6 fits into the groove 17 without sliding into contact with the rubber, thereby preventing the spike body 6 from inadvertently standing up and stably maintaining the unused state. The spike body is always stored in the heel and does not protrude into the arch of the foot, so it does not become an obstacle when pedaling on a bicycle or going up and down stairs, and it is lightweight because it does not use metal spikes. When the shoe is not in use, the spike studs enter the blind hole 21, making no noise when walking and providing good comfort.

It makes no noise and is comfortable to wear.

Furthermore, the plate made of hard thermoplastic synthetic resin and the heel part made of elastic rubber press the rubber and fit into the groove 17 without slidingly contacting the rubber, and the heel part is formed by the pressing ridge of the spike body. This prevents wear of the rubber of the spike body, ensures smooth rotation of the spike body without wobbling over a long period of time, and maintains the spike body stably when used as a non-slip device and stably maintained when not in use. This has the effect of providing a secure anti-slip device for shoes.
