Description

The present invention relates to an anti-slip safety device, and in particular, a ring-shaped or spiral anti-slip component is arranged and directly and integrally formed with a main body made of a rubber / resin material such as a sole or a tire, thereby providing a strong and secure connection. Anti-slip, which is possible to prevent slipping by providing a slightly protruding convex edge surface and a convex pattern on the grounding surface at the same height and meshing firmly with the snow and ice surface layer. It relates to safety devices.

In general, when walking on a snowy road, it is necessary to wear shoes having a special snowy road spike structure, and when using a vehicle, it is necessary to attach a snowy road chain for safety. If these measures are not taken, slipping is likely to cause safety concerns. The most common anti-skid structure for ice and snow shoes is most commonly seen in US Pat. No. 5,634,283, where a metal T-shaped spike part is attached to the bottom end. This is a structure that is placed in a molding mold of a rubber heel and directly pressed together with the rubber material of the heel so that the thin rod protrudes slightly. Spikes made of metal have high hardness, and when molded by covering the bottom of rubber / resin, if the material of the bottom of the bottom is insufficient, the soft elastic rubber / resin is insufficient in hardness and rigidity. The spike parts head protrudes into the shoe due to the recoil of the landing without receiving the instantaneous repulsive force generated by the pressure of the surface and the unevenness of the ground. This causes partial discomfort on the soles and injuries the soles in severe cases. Also, at the time of molding, spike parts must be inserted into the bottom cavity one by one and fixed, which not only requires labor and technology, but also when molding with rubber and resin materials, rubber and resin are soft and fluid Therefore, the depth to insert and fix the spike parts is insufficient (the part inserted into the cavity is only the length of the part protruding after molding), and the spike is molded in an oblique state. There is often. If it becomes oblique, it will have a great influence on the anti-slip effect when landing on the bottom of the heel. A structure in which spikes are inserted deeper into the mold to improve the stability of fixing is disclosed in EP 1 290 958 A3. In this structure, the holes into which the spike parts are inserted are provided in a slightly long convex ring shape, and the spike parts are arranged in an orderly manner without being biased by the material by forming a space for covering firmly. Such a structure with a changed mold may assist fixing by making the insertion space deeper as described above, but when the spike is covered on the bottom of the spike, it is not covered on the bottom end of the spike. Since the portion remains, the length of the covering is not sufficient, and the fixing strength of the spike is insufficient. In particular, it is difficult to completely bond between a metal nail bar and a soft elastic saddle, and spikes are likely to fall off due to pressure applied during use. Then, although the contractor performed the hardening process to the bottom material, the bottom material was too hard, and conversely, the comfortable elasticity of the bottom was insufficient. This has long been a difficult and blind spot in manufacturing development.

Example 1
The anti-slip safety device of the present invention has a stable and safe anti-slip structure when used in combination with a rubber / resin material. First, referring to FIGS. 1 to 4 for an embodiment used for general anti-skid bottom slip. The non-slip structure on the bottom of the heel is such that the anti-slip components 11 arranged at intervals are attached to the mounting concave grooves 21 provided in advance in the shoe sole mold 20 when the shoe body 10 is molded. Become. At this time, since the length of the concave groove 21 and the length of the anti-slip component 11 to be accommodated are the same, after being combined, they are engaged and fixed together. Further, the anti-slip component 11 is formed in a spiral shape wound at an appropriate interval, and one end of the anti-slip component 11 extends vertically to form the end ring 12. The anti-slip component 11 has a structure that protrudes substantially at the same height as the anti-slip convex pattern 13 on the bottom surface, and since the space between the convex patterns 13 is recessed, the convex edge surface 14 of the anti-slip component 11 is naturally convex. Exposed to. In the case of a general bottom material, the exposed height is usually 3 mm or less, and an anti-slip effect by engagement can be obtained. Generally, the shape of the sole is preferably 1 to 3 mm. After the non-slip component 11 is inserted and fixed in the mounting groove 21 provided continuously to the shoe mold 20, the sole body 10 and mold-molded. The non-slip component 11 is determined in accordance with the appearance shape of the sole body 10 and the arrangement of the pattern, and is usually arranged and attached. The pieces are distributed. In addition, anti-slip parts 11 having an inclination angle (A) slightly outward are provided on both the front and rear ends of the heel, that is, the bottom surfaces at positions corresponding to the toes and the heel. Because the meshing of the irregular direction due to the inclination provides a non-slip effect against the force from the side, even if the ground surface is hard and slippery or not flat when the bottom of the heel is landed, different directions It is possible to prevent slipping. Further, the structure of the anti-slip component 11 is formed by a spiral component having a gap, and a single ring-like component provided separately may be arranged with a gap and may be put in a mold ( (See FIGS. 5 and 6). Alternatively, an independently molded ring-shaped part is inserted into the inner edge of the bottom covered with a rubber / resin material, and the ring-shaped parts are connected to each other by a connecting rod part (not shown). ), It is covered safely by continuously receiving force and directly embedded in a rubber / resin material, and the bottom surface of the shoe sole body 10 has a protruding edge surface 14 similarly protruding. The structure of the non-slip component 11 formed by arranging independent ring-shaped components can be arranged in a wedge-shaped or arc-shaped ring according to the shape or pattern of the bottom of the heel. In addition, the arrangement direction of the anti-slip parts 11 is arranged linearly at intervals so that portions extending in the axial direction are perpendicular to each other, and the convex edge surfaces 14 extending on both sides are arranged in parallel to each other ( (See FIG. 4). With the above structure, the anti-slip effect in the axial direction and the lateral direction is achieved. Further, even in a structure using a single ring body, by arranging them at intervals, a continuous anti-slip effect by meshing can be achieved similarly.

The anti-slip component 11 of the present invention is formed by arranging ring-shaped components at appropriate intervals in a row or by a spiral component. Therefore, the anti-slip component 11 is integrally formed with the sole body 10 and then bends and deforms upon landing according to the flexibility of the sole body 10, thereby affecting the comfort and grounding stability. It has the feature that there is nothing. Further, the exposed convex edge surface 14 is bent and deformed according to the bending state of the contact surface, and is completely in contact with the surface of the snowfall and meshes firmly. As a result, it can be used as footwear with a reliable ground contact and a safe anti-slip effect. Further, the anti-slip component 11 is provided in a concave space formed on the inner surface of the convex pattern 13 on the ground contact surface of the shoe sole body 10 to form a strong bond substantially covered with the heel material, thereby preventing slipping off and displacement. Suitable for the purpose. In addition, the anti-slip component 11 is made of a rigid metal material and is connected to each other by being arranged in a single ring or in a spiral shape with a space therebetween, and is slightly expanded and contracted. Thus, since the necessary anti-slip effect can be obtained, the force cannot be supported and cannot be pulled out unlike the conventional single spike pin. The arrangement or the spiral non-slip component 11 which is integrated with a certain interval can obtain a safe and reliable anti-slip effect because a plurality of spaced points on the convex edge surface 14 mesh with each other to receive the force. . The structure that is almost completely covered with the heel material allows the shoe sole body 10 to be securely and securely joined, so that a dangerous situation such as falling off or shifting does not occur. In addition, since the anti-slip component 11 formed in a spiral shape is provided with a protruding end ring 12, a spirally connected structure or a ring arranged separately in the recovery processing of the bottom material With the aid of a connecting rod that runs through the body, it can be easily removed with a tool. Thereby, it has the convenience that it is easy to carry out classification collection and processing for environmental protection. Furthermore, since the convex edge surface 14 protruding from the anti-slip component 11 and the surface of the convex pattern 13 on the bottom of the heel are structured to be the same height, they are made of rubber or resin when used indoors. The bottom of the heel bottom and most of the ground are in contact with each other, and it is difficult to walk or damage the floor. Therefore, it can be used both indoors and outdoors, and can be said to be a non-slip structure with a bottom that is highly practical.

(Example 2)
Further, the anti-slip structure of the present invention is used as an anti-slip material on the large and small tire surfaces made of general rubber / resin. Please refer to FIGS. The metal anti-slip component 11 formed in a spiral shape is positioned by a housing groove 41 provided in a slightly depressed shape on the curved surface between the tire patterns in the molding die 40 of the tire outer layer 30. It is pressure-molded together with the rubber and resin material filling the tire surface. As described above, the anti-slip component 11 is directly and completely covered and molded on the tire outer layer 30, and portions protruding about 5 mm or less are evenly arranged on the curved surface of the tire pattern 31. Since the circumference size and arrangement direction in the actual structure can be changed appropriately according to the load of the tire and the demand for the ground contact location, the vehicle protrudes from the anti-slip component 11 when the vehicle runs on an icy and snowy road surface. The raised edge surface of the gold bar material engages with the frozen surface layer firmly, and can exhibit an anti-slip effect when the vehicle is running. As described above, it is possible to prevent slippage when the vehicle travels, which is not particularly troublesome by the attachment of the conventional snowy road chain and is not likely to come off, and is particularly suitable for use in a high latitude region. The anti-slip structure at the time of tire rotation is a structure having novelty that has never been seen in the past in the same type of anti-slip structure.

The features of the present invention are as follows. The non-slip component 11 is formed of a rigid metal wire having a hollow shape and wound into a spiral having an appropriate length, and is covered and integrally formed when the shoe sole body 10 is molded. There is no worry. In addition, since the protruding edge surface 14 slightly protruding on the bottom surface is aligned with the protruding pattern 13 on the bottom surface, there is no fear that the protrusions damage the floor in the room when worn indoors. In addition, when walking on a slippery ground frozen outside, the bottom of the heel is appropriately bent along the unevenness of the ice and snow surface to make a proper contact with the ground, and the convex pattern 13 of the heel is deformed so as not to slip. At this time, even if the bottom of the saddle is deformed according to the bending, the slightly protruded convex edge surface 14 of the anti-slip component 11 is not deformed due to the rigid material, and meshes with the ice / snow surface to be comfortable and safe during walking. A non-slip effect can be obtained. The combination of the above-described anti-slip structure and an appropriate arrangement enable safe anti-slip of the sole at the time of walking or safe anti-slip at the time of tire rotation. Further, the anti-slip component 11 has a structure in which it is positioned and molded in advance by a mold, so that it is possible to reduce production costs in addition to greatly simplifying the manufacturing technique. Furthermore, the spiral non-slip part 11 can be filled with a conventional elastic part wound in a spiral shape at an appropriate length. The anti-slip component 11 can be provided with a linear shape or a shape connected to each other at an appropriate inclination angle, thereby enabling a structure having a simple and diversified anti-slip effect. In the present invention, the structure of the non-slip component 11 in which the convex edge surfaces 14 arranged at intervals protrudes and is integrally molded is not only a unique anti-slip structure, but also an epoch-making anti-slip component. The simple and strong structure that can exert the effect has novelty in the same kind of bottom or tire non-slip structure.
