The invention in particular is attached to the sole/heel of the shoes worn especially over snowy/icy surfaces in wintertime and configured for preventing injurious slips and falls that may occur during walking on snowy/icy surfaces, as follows;

- it relates to such a mechanism that there are a plurality of arms and spikes located inside of its main housing, and that in order to prevent any injurious slip of a person equipped with this mechanism; the slip-preventer elements are enabled through an actuating lever causing the spikes come into contact with the surface, and that if there is no snowy or icy surface, the mechanism is disabled, and it comprises of a main housing, compression springs, slip preventers moving part and compression part, actuating lever and lid.

FOR ME R TE C HNIQU E

In wintertime, snow/ice covers the roads and pavements on which people walks due to the weather conditions. People are required to walk on snowy / icy grounds, while trying to move from one place to another for their work in their daily lives.

The shoes worn by people tend to slip on snowy/icy grounds and accordingly cause them slip and fall that results physical in injuries. In the state of the art, there is nonslip soles developed for shoes/boots worn by people over snowy / icy surfaces, although it is assumed to be nonslip, by virtue of the fact that the soles of the said shoes/boots are made of rubber, and the rubber material hardens in cold weathers, therefore hardened rubber becomes slippery over snowy / icy grounds.

In the investigation of the state of the art, a patent application numbered

W02008046491 under the title of "Rotating anti-slip device for soles of footwear" has been found. In the abstract section of the application it is expressed that "the present invention relates to the shoe industry and a device is placed on the sole of a shoe and the person is required to equip his/her own shoe and easily prevents slips over snowy / icy asphalt pavements. S ince slip risk is high over snowy / icy asphalt pavements and also physical injury likeliness is possible, it is designed to prevent more serious occasions especially for certain persons or in certain cases".

When the abstract and content of the patent application numbered

W02008046491 is reviewed in detail, the subject matter seems to be an invention relating to an apparatus / device that is externally integrated to the base of the shoe for snowy / icy surfaces. These devices /apparatuses requires additional efforts such as carrying additional apparatuses to shoes, installation, removal, screwing of additional apparatus and restoration of the shoes. This situation brings time and cost losses along with it apart from additional efforts.

Due to the above mentioned negativity and problems encountered in the known case of the technique, as a result, an improvement is required in the respective technical field.

In the assembling process of the mechanism (A) of the invention subject, the compression springs (20) are connected to the spring cups (12) available in the main housing (10).

S lip preventer (30) is inserted through assembly gap (31.1 ) one by one into each horizontal pin (13) in such a way as to be positioned over the compression springs (20). At this stage, the spikes (32) on the slip preventer (30) are facing passage holes (14) and compression springs (20) are going into the positioning cavities (31.2).

The moving part (40) is positioned in such a way that the pressure arms are located over the slip preventers (30), and then the pressure piece (50) is positioned over the moving part (40). Rear tennon (51 ) available on the pressure piece (50) is inserted into the channel (1 1.1 ) available on the support (10), and front tennon (52) available on the front section, is inserted into the mortise available on the moving part (40). Actuating lever (60), assembly hole (61 ) is connected to the fixed pin (16), and the slot (62) to the upper pin (43) and its tip as protruding outward is connected to the main housing (10). F inally, the lid (70) is put onto the main housing (10).

The mechanism (A) is attached to the sole of the shoe after it is assembled as described above.

Views representing the mechanism (A) of the subject of invention in the

deactivated state in F igure 9, and that of the mechanism of the subject of invention in the activated state in the figure 10 are demonstrated.

When the shoe is in the dry section, the mechanism (A) of the invention subject is deactivated as shown in Figure 9. In this operation the user is moving the actuating lever (60) towards right as shown with an arrow in the figure 9.

Compression springs (20) push each slip preventer (30) upwards.

The mechanism (A) is required to be activated over the snowy / icy grounds. In this operation the user is moving the activating laver (60) towards left as shown with an arrow in the F igure 10. At this stage the moving part (40) exerts a pressure to the arm (31 ) of the slip preventer (30) from the top and overcomes the force of compression springs (20) and thus spikes (32) protrude outward through the passage holes (14) and the mechanism (A) is activated. Deactivation or activation of the mechanism during the stage of use is carried out practically when the user controls via the actuating lever (60).
