Abstract

Disclosed is an anti-skid shoe sole which provides reliable guarantee of safety and skid resistance for pedestrian walking on snow and ice pavements or smooth pavements. The periphery of the anti-skid shoe sole is particularly provided with an outer inclined tongue-shaped soft rubber anti-skid skirt structure, and the inner side wall of the anti-skid skirt is provided with a plurality of ring-shaped grooves whose bottoms forms circular bead shapes and are arranged in a contour line form. The elastic action of the anti-skid skirt ensures the anti-skid shoe sole and the anti-skid skirt both contact the ground by large area in each landing time of the heel part of the anti-skid shoe sole and the anti-skid skirt, and thus, the frictional force between the anti-skid skirt of the shoe sole and the ground in each landing time is increased, so that users can not slide to be hurt when walk on snow and ice pavements or smooth pavements.

Description

Slip-preventing shoe soles

The utility model belongs to article of footwear.

People walk on ice and snow road or smooth road, and careless slightly just can slipping got injured by a fall, and special centering, its harm of the elderly are more so.Slip is to cause owing to frictional force is little between sole and the road surface.

General footwear, the morphological feature of pressing sole can be divided into walking shoes, Slope sole shoes and have the footwear of differing heights heel.Be the frictional force of increase with the road surface, the bottom surface of sole is processed to various forms of rills.When people walked, the sole each several part had certain rule with the priority contact site on road surface.For majority, the sole site that contacts with the road surface is the heel rear outside end that supports the human body body weight at first, indivedual artificial medial extremitys.In the moment that heel rear outside end or medial extremity contact with the road surface, its contact condition is similar to the point-like contact, or very little planar contact.If this moment, the frictional force that this contact condition will reduce sole and road surface more formed the main cause that slips and get injured by a fall for people on ice and snow road or smooth road.

The utility model provide a kind of can be at the bottom of heel and road surface contacted moment just begin to keep the on-slip shoes of big frictional force with the road surface, to overcome the shortcoming that general sole makes the people slip easily.Be suitable at the bottom of this on-slip shoes and be processed into Slope sole shoes or walking shoes.

Structure at the bottom of the on-slip shoes such as accompanying drawing, accompanying drawing are the three-face view at the bottom of the on-slip shoes, and be positive for front view (Fig. 1), right side are side view (Fig. 2), is vertical view (Fig. 3) below.Side view is cut open by the centre, vertical view partly cut-away.Structure at the bottom of the on-slip shoes is the anti-skidding skirt (1 among Fig. 3) that has a circle to protrude around sole face edge, and anti-skidding skirt section is the del of ligule, top section broad, and the bottom is constriction gradually.Anti-skidding skirt stretches out laterally, and its lateral surface inclination angle is 25 °～50 °.Anti-skidding skirt vertical height 7～25mm.The front-end and back-end of anti-skidding skirt can be same height, also can make higher and the anti-skidding skirt of sloping shape that front end lowers gradually in rear end.There is a gap (1 among Fig. 1) anti-skidding skirt front end or inboard, in order to the atmospheric pressure balance between adjusting when anti-skidding skirt contacts fully with the road surface inside and outside the anti-skidding skirt.The madial wall of anti-skidding skirt can have difform rill, as straight, oblique, rhombus or have the bottom is contour formula arrangement for the garden horn shape a round groove (1 among Fig. 2).Adopt the material mold pressings such as soft rubber of good springiness under the low temperature to form at the bottom of the on-slip shoes, as foaming synthetic rubber or thermoplastic rubber etc.

Anti-skidding at the bottom of the on-slip shoes is because the anti-skidding skirt of sole is outward-dipping tongue structure, and has elasticity preferably.When the moment that the anti-skidding skirt of sole heel contacts with the road surface, anti-skidding skirt is distortion upwards, causes part sole and anti-skidding skirt to contact with the road surface simultaneously, has increased contact area so greatly, has increased frictional force therebetween.This often emits the gas in the tire with by bike people on ice and snow road, and the reason anti-skidding by the contact area that increases tire and road surface is close.

Advantage at the bottom of the on-slip shoes is on ice and snow road or smooth road, each moment that the anti-skidding skirt of sole contacts with the road surface can both keep bigger frictional force with the road surface, has guaranteed that then it makes people be difficult for slipping with the firm contact on road surface.

Embodiment of the present utility model as shown in drawings, its anti-skidding skirt lateral outer incline angle is 45 °.The high 10mm in anti-skidding skirt rear end is reduced to 7mm forward gradually.There are four bottoms to be the round groove (1 among Fig. 2) that the contour formula is arranged on the anti-skidding skirt inwall for the garden horn shape.Anti-skidding skirt is made with soft rubber material.

Claims

1, at the bottom of a kind of on-slip shoes, be specially adapted to Slope sole shoes and walking shoes that the bottom surface is a domatic, it is characterized in that having one to enclose the anti-skidding skirt of ligule that protrudes around the sole, the section of anti-skidding skirt is a del, upper wider bottom narrows down, anti-skidding skirt stretches out laterally, and the inclination angle of lateral surface is 25 °～50 °, and anti-skidding skirt height is 7～25mm;

2,, it is characterized in that the madial wall of anti-skidding skirt has decorative pattern at the bottom of the on-slip shoes by at the bottom of the said on-slip shoes of claim 1;

3, by at the bottom of the said on-slip shoes of claim 2, it is characterized in that on the anti-skidding skirt madial wall many bottoms being arranged is the garden horn shape, be the cast groove decorative pattern that the contour formula is arranged;

4,, it is characterized in that at anti-skidding skirt front end or the inboard gap that has ventilation by the said anti-skidding skirt of claim 1;

5, by the said anti-skidding skirt of claim 1, the soft rubber of good springiness or flexible glue moulding material are made under the available low temperature;

6, by at the bottom of claim 3,4, the 5 said on-slip shoes, it is characterized in that the anti-skidding skirt lateral camber angle at the bottom of the on-slip shoes is 45 °, the high 10mm of the anti-skidding skirt of sole heel, forward end is reduced to 7mm gradually.It is the garden horn shape that four bottoms are arranged on its madial wall, is the round groove that the contour formula is arranged.The ventilation gap is positioned at front end.Soft rubber with good springiness under the low temperature is made.
