An anti-ice and anti-snow bottom for application under the shoe sole

Abstract

 The present invention relates to an anti-ice and anti-snow bottom having a configuration similar to "box-type" shoe bottoms (1), with anti-slip tread (6) and straps (3,5) for application on the shoe (5).

Description

[0001] The present patent application for industrial invention refers to an anti-ice and anti-snow bottom for shoes to be temporarily applied under the sole of winter shoes in the presence of ice and snow on the ground.

[0002] The manufacture according to the present invention is an absolute novelty, being the first accessory for standard shoes devised to improve grip on icy and snow-covered ground.

[0003] As regards climbing boots, special crampons that ensure safe, balanced walking and climbing on alpine glaciers have been known on the market for a long time. They consists in metal grids having the same shape as the foot, provided with multiple teeth capable of carving and gripping on icy surfaces. The crampons are provided with straps and clips used to attach them under the sole of climbing boots.

[0004] These hooks are extremely useful to climb mountains, but cannot be used by ordinary pedestrians to improve the anti-slip qualities of their shoes.

[0005] As it is known, winter shoes usually have bottoms made of rubber or similar materials, with engraved tread in order to ensure good anti-slip properties on wet or snow-covered ground. However, they are totally inadequate to provide anti-slip performance on icy surfaces, on which pedestrians find it extremely difficult to keep their balance, with the risk of dangerous falls that may cause serious injuries, especially in the case of elder people.

[0006] In view of the above considerations, a special anti-ice bottom for ordinary winter shoes has been devised, characterised by easy transportation, simple and fast application and low cost.

[0007] The bottom according to the present invention basically consists in an ordinary bottom for shoes, moulded with polyurethane, natural or synthetic rubber or similar materials. It has the so-called "box-type" configuration, characterised by a high perimeter edge that delimits and surrounds a deep central cavity capable of housing the sole of the shoe on which the bottom according to the present invention is applied.

[0008] The tread of the bottom according to the present invention is covered by a dense series of pointed protuberances, in some of which metal nails are inserted.

[0009] The bottom can be fixed to the shoe using two transversal straps that are inserted in buckles located on the internal side and then folded over. The straps are provided with Velcro sections for fast closure, with the possibility of tightening them as necessary.

[0010] For major clarity the description of the present invention continues with reference to the enclosed drawings, which are intended for purposes of illustration and not in a limiting sense, whereby:

• Fig. 1 is a perspective view of the bottom according to the present invention;
• Fig. 2 is a perspective view of a shoe on which the bottom according to the present invention has been applied.
• Fig. 3 is a cross section of the bottom.

[0011] With reference to the above figures, the bottom (1) according to the present invention is an ordinary bottom for shoes of "box-type" with larger dimensions since it must house the bottom (F) of the shoe (S).

[0012] More precisely, the bottom (1) consists in one moulded piece with high perimeter edge (2) capable of covering and protecting the sides of the bottom (F) of the shoe (S) externally, as shown in Fig. 2.

[0013] Two transversal straps (3) are fixed, with stitches in this specific case, on the external side of the edge (2) that are tightened over the shoe on the toes and the instep.

[0014] The two straps (3) are inserted in buckles (4) located on the internal side of the bottom (1) and then folded over. The same straps (3) are provided with Velcro sections (5) for fast closure, with the possibility of tightening them on the shoe (S) as necessary.

[0015] The tread of the bottom according to the present invention is covered with a dense series of pointed protuberances (6).

[0016] On the bottom (1) are also inserted metal nails (7), emerging on the tread surface.
