A SKID PREVENTION DEVICE FOR SHOES
BACKGROUND OF THE INVENTION
Field of the Invention:
The present invention relates to a device for shoes to prevent a skid when a user walks on the icy road in winter. A pedestrian can't walk properly on the icy roads when
the temperature drops suddenly after snowing or raining in winter. And the sliding to the icy ground causes an accident, which happens usually at a slope way. Especially the old people, who walk with unsteady steps, would get a serious wound.
Description of the Prior Art:
The present invention is about the device for shoes to prevent a skid when users walk on the icy road in winter. A pedestrian can't walk properly because of the icy roads when the temperature drops suddenly after snowing or raining in winter. And the sliding
to the icy ground causes an accident, which happens at a slope way. Especially the old people, who walk with unsteady steps, would get a serious wound.
SUMMARY OF THE INVENTION
The present invention is contrived to solve these problems. The present invention has the upper saw-teeth 2, 2' and 2 A on the upper side of main board, which will contact
with the shoes, and the bottom saw-teeth 3, 3', 3 A, 3B on the bottom of main board, which will contact with the icy road. The metal support board 1 has holes 4, 4', 4" for the
band and holes 5, 5', 6, 6' for the resilient strings. The band 7 is inserted through holes 4, 4', 4" and fixed with an adhesive magic tape 8, 8'. A resihent string 9 is inserted through holes 5, 5' and the other resilient string 10 is inserted through holes 6, 6' and both strings tighten the device with the shoe. The upper saw-teeth 2, 2', 2A contact with the bottom
of the shoes, and the band 7 is tightened with an adhesive magic tape 8, 8'. At last, the front string 9 will be fixed to the front part of shoe 11, and the other string 10 will be fixed to the heel of shoe 11. Therefore, it is the well-organized skid prevention device for the effective way of the accident avoidance.
BRIEF DESCRD7TION OF THE DRAWINGS
The aforementioned aspects and other features of the present invention will be explained in the following description, taken in conjunction with the accompanying drawings, wherein:
Fig. 1 is the perspective view of the present invention. Fig. 2 is the cross-sectional view of the present invention.
Fig. 3 shows a state that the invention is put on.
EXPANATION OF THE MAIN COMPONENTS
1 is a metal support board. 2, 2', 2A are the upper saw-teeth.
3, 3', 3 A, 3B are the bottom saw-teeth.
4, 4', 4" are holes for the band.
5, 5' are holes for the front string.
6, 6' are holes for the back string. 7 is a band
8, 8' are adhesive magic tape 9, 10 are a resihent sting
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS The present invention has the upper saw-teeth 2, 2 2 A on the upper side, which contact with the shoes, and the bottom saw-teeth 3, 3', 3 A, 3B on the bottom, which contact with the icy road. The metal support board 1 has holes 4, 4', 4" for the band and holes 5, 5', 6, 6' for the resihent strings. The band is inserted through holes 4, 4', 4" and
fixed with adhesive magic tape 8, 8'. A resihent string 9 is inserted through holes 5, 5' and the other resilient string 10 is inserted through holes 6, 6' and both strings tighten the device with the shoes. The upper saw-teeth 2, 2', 2A contact with the bottom of the shoes, and the band 7 will be tightened with adhesive magic tape 8, 8'. And finally the front string 9 will be fixed to the front part of the shoe 11, and the other string 10 will be fixed to the heel of the shoe 11. In other words, it, surely, is the well-organized skid prevention device with the consideration of the effective skid avoidance methods.
The present invention will be described in detail by way of a preferred
embodiment with reference to accompanying drawings.
Fig. 1 is a perspective view of the present invention. And fig. 2 is a cross-
sectional view of the present invention.
As drawn in Fig. 1 or 2, it has saw-teeth 2, 2', 2A on the upper side, which contact with the shoes, and saw-teeth 3, 3', 3 A, 3B on the bottom, which contact with the icy road. The metal support board 1 has holes 4, 4', 4" for the band and holes 5, 5', 6, 6' for the resilient strings. The band is inserted through holes 4, 4', 4" and fixed with adhesive magic tape 8, 8'. The front resihent string 9 is inserted through holes 5, 5' and
the back resilient string 10 is inserted through holes 6, 6' and both strings will be tightened. The saw-toothed metal board 2, 2', 2A contacts with the bottom of the shoes, and the band 7 is tightened with adhesive magic tape 8, 8'. And finally the front string 9 will be fixed to the front part of the shoe 11, and the other string 10 will be fixed to the heel of the shoe 11.
The unmentioned index 12 means the sole.
As mentioned above, the present invention contacts with the sole 12 and tightens itself with the shoes fastening the band 7, using the adhesive magic tape as shown in Fig 3.
And the front resilient string 9 is fixed to the front part of the shoe 11 and the
back resihent string 10 is fixed to the heel of the shoe 11 tightly. So the bottom saw-teeth
3, 3', 3 A, 3B prevent from users sliding.
Referring to the Fig. 2, the upper saw-teeth 2, 2', 2 A, which are integrated with the metal support board 1, are contacted with the sole, so that the saw-toothed board can keep stable balance. Consequently, it is excellent at the skid prevention effectiveness. Also it can be carried with a small bag or kept in a shoe chest after
disconnect them from the shoes when unused.
At that time the resihent strings 9, 10 will be shrunk to small size so that the carrying and keeping is very simple. Also the band 7 could be made from resihent materials by manufacturing method.
