Description

[Detailed description of the invention] This invention relates to spiked soles with spikes attached to the soles of boots etc. More specifically, it is a shoe with spikes to prevent slipping when walking on snow in snowy and cold regions. This relates to a shoe sole with spikes that can be used like normal shoes by folding down the spikes when not in use.

As shown in FIGS. 1 and 2, conventional shoe soles with spikes include a spike support metal fitting (A) provided on the arch of the sole, a spike (2) rotatably attached to the spike support metal (B), and a spike (2) attached to the front end of the spike (3). The spikes are supported by constantly pushing them up with the spring plate (2) of the support bracket (B).When in use, the spikes are raised toward the heel as shown in Figure 1, and when not in use, they are raised up against the arch of the foot as shown in Figure 2. I try to fold it up.

However, when the support metal fittings and spikes are attached to the arch of the foot in this manner, various problems occur when the shoe is used as a shoe. That is, when riding a bicycle with these shoes, the spikes etc. hit the pedals, making it difficult to pedal, and when going up and down stairs, the spikes etc. hit the edges of the stairs, making it easy to trip.

Further, if the spikes are supported by the spring plate 2 as shown in the figure, the lower surface of the spring plate 2 becomes clogged with snow or mud, which prevents the spring plate 2 from moving downward, making it difficult to rotate the spike fin. Furthermore, spring plates etc. are prone to rust as they are constantly exposed to snow, water, mud, etc. If used for a long time, the rust will cause the spring plates to lose their elasticity, ensuring that the spikes are in the correct position. The disadvantage is that it cannot be maintained. In particular, snow tends to adhere to metal, and even if it melts, it remains as moisture, and since these springs are located in the soles of shoes, they are not properly maintained, which greatly accelerates the progress of rust.

The purpose of this invention was to allow spikes to be attached that can rotate freely without the arch of the foot becoming an obstacle like normal shoes, and to prevent the rotation of the spikes from being obstructed by snow, mud, etc. The goal is to ensure that there are no Also, the springs that fix the spikes during raising and lowering can be protected from snow, water, mud, etc.

To explain this invention with reference to an embodiment shown in the accompanying drawings, a recess 3 is provided in the heel 2 of a rubber shoe sole 1, a spike support fitting 4 is provided in the recess 3, and the front end of the spike 5 is provided in the spike support fitting 4. 5' is rotatably supported, and a claw 7 is attached to the rear end of the spike 5.
, two cut grooves 9 are provided in the recess 3 below the front end portion 5', and a metal fitting 10 having a U-shaped cross section is fitted between the cut grooves 9 to form the elastic member 8. The sole has spikes.

In the figure, reference numeral 11 denotes a middle claw which is shorter than the claw 7, and when the claw 7 is worn out and has no anti-slip effect, the middle claw 11 serves as an anti-slip. 12 is middle nail 11
A groove 13 is a locking portion of the recess 3 and locks the spike 5 during use. The front end of the recess 3 is formed to such a length that the claw 7 does not touch when the spike 5 is folded.

14 is a U-shaped spike support fitting 4 and a back metal 15
The spike support fitting 4 and the backing metal 15 are fastened to the sole of the shoe via the studs 14. Since this device is as described above, in use, from the folded state of the spike 5 as shown in FIG. 4, hold the rear end of the spike 5 and rotate it as shown by the arrow A5. The spike 5 is used by being locked to the locking part 13 as shown in FIG. At this time, as the front end 5' of the spike 5 rotates, the metal fitting 10 first
The elastic member 8 is compressed downward through the
When the rear end of the spike 5 rotates close to the locking part 13, the elastic member 8 tries to return from the compressed state to its original state, pushing up the front end 5 of the spike 5 and preventing the rotation of the spike 5. The spike 5 is reliably locked to the locking part 13.

As explained above, in this invention, since the spikes 5 are provided in the recess 3 of the heel part 2, the spikes 5 do not become an obstacle when riding a bicycle or going up and down stairs. Further, the elastic member 8 has a cut groove 9 in the recess 3, and the cut groove 9 is connected to a metal fitting 10 having a U-shaped cross section.
It can be formed simply by fitting the rubber, so the elasticity of the rubber can be used as is.
