Background technology

Although we have found that various devices are designed to be mainly used on the heavy boots, so that under icing and snowy condition, use, but up to now, we still do not find any universal accident prevention system, can be used in reliably dangerous situation, comprise the dangerous ground in bituminous paving and rural, and can be installed in the footwear of any kind.

We are considered as a kind of simple fexible unit with " pawl ", are used for using at once, solve the problem of balance and risk of falls effectively.

" pawl " is designed to interim use, and as umbrella, but Sometimes When It Rains also not becoming a kind of obstacle, because when not in use, it keeps being wrapped in the heel, and does not influence the outward appearance or the usefulness of footwear.

Summary of the invention

" the general antiskid claw that is used for footwear " (referring to Fig. 1 and Fig. 5) is a kind of universal device, and it is designed in when industry is made and is installed in various types of footwear, and the people who is used to walk on smooth earth to having to provides safe condition.

" universal antiskid claw that is used for footwear " is installed to the city shoe of being made by any material, the heel or the outer bottom of sport footwear, adopts such as leather, rubber, polyurethane, vinyl and other material.

This antiskid claw is made by stainless steel, and anti-sealing infiltration is used easily, Maintenance free, and the weight of the big manyfold of body weight that can the CBR mediocrity.

At any time can use hand primer easily to it, even child or old man, without any need for the help of external device (ED).

" the general antiskid claw that is used for footwear " is a kind of invention that comprises following structure and purposes:

The vertical piston (referring to Fig. 2 and Fig. 6) of-organization center mechanism band cannelure forms and allows all multiple mechanical functions, specifies as follows:

A)-support " zigzag horseshoe type bar " or another kind of mode " zigzag cross bar "; (referring to Fig. 1 and Fig. 5)

B)-its motion causes discharging and the bar of the tooth of withdrawing; (referring to Fig. 2,4 and Fig. 6,7)

C)-special " cannelure " structure (referring to Fig. 2 and Fig. 6) guarantees level and smooth operation and " pawl " can be navigated in the heel Anywhere, do not hinder this bar optional operation angle on the ground.

By rotating release and the withdrawal (referring to Fig. 3) that the lug driven plunger realizes serrated bar by hand, this lug is positioned at the outside of singly-bound, described singly-bound have the eccentric head of in cannelure, rotating (referring to Fig. 2,4 and Fig. 6,7).

Serrated rod has two kinds of different patterns now, has following two kinds of different functions:

-" zigzag horseshoe type bar " (referring to Fig. 1) is used in the heel of footwear;

-" zigzag cross bar " (referring to Fig. 5) is used in the outer bottom.

The use of circular groove piston also makes " pawl " can be positioned in the outer bottom Anywhere, does not influence bar optimum operation angle on the ground again.

Each position of bar is interchangeable; Yet, verified to the laboratory tests of the operation of " pawl ", the horseshoe type bar is installed in the heel and transverse bar is installed in and obtain optimum efficiency on the outer bottom.

Can realize the profile of tooth rod is withdrawn fully by being reversed manual operation, thereby make footwear get back to normal use.

Mention " cannelure " structure of piston above especially, this structure can make " pawl " to be installed in the heel Anywhere, and does not change bar promptly angle (referring to Fig. 1 and Fig. 5) on the ground, the length " L " that need come the adjusting key arm in some position.

Key is suitable for the operation requirement of " pawl ", owing to adopt:

-O shape ring packing ring, its prevention of water infiltration; (referring to Fig. 2)

-fixing banking pin; (referring to Fig. 2)

-do not need extra device to realize its starting/stop using;

" pawl " do not hinder normal walking, because people's body weight is evenly distributed in by means of the thickness of bar on people's the calcaneal whole surface.

Exist under the condition of risk of falls, it is permissible on physiology that heel of a shoe is raised 5mm.
