Description

Technical field

This invention relates to an anti-skid chain using used tires, and more particularly, to an anti-skid chain made of used tires that can economically reuse used tires using used tire cushions obtained by dividing used tires as friction material.

BACKGROUND OF THE INVENTION

Usually, an urethane cushion or a steel chain is used as a friction material in an anti-skid chain.

However, when a urethane cushion is used in the anti-skid chain, with large temperature fluctuations, the urethane cushion may break and the cushion must be replaced with a new one, often due to heavy wear. Moreover, a selection by type is necessary because anti-skid chains are made of different types according to tire sizes, and the cost of their production is high, since the material of urethane cushions is expensive.

At the same time, an anti-skid chain using a steel chain has better braking force than an anti-skid chain using a urethane pad, but it is difficult to install because of its heavy weight and makes noise when traveling. Moreover, an anti-skid chain using a steel chain can damage the tire and the road surface on a paved road due to high rigidity.

Moreover, with the development of the automotive industry, environmental pollution by the disposal of used tires grows into a social problem. Typically, spent tires are eliminated by burning. However, when used tires are burned, due to the sulfur element contained in the tires, many harmful gases and elements, such as sulfur dioxide gas, are formed, thereby causing severe environmental pollution. In addition, the removal of spent tires is a huge expense, as the tires are burned after the wire cores in the tires are separated from the tires.

Therefore, various attempts have been made to solve the above problems. For example, US Pat. No. 6,016,856 discloses a clutch device for tires (with reference hereinafter as Document 1 of the prior art) and US Patent No. 3856068 discloses a clutch device (with reference further as Document 2 of the prior art).

As shown in FIG. 1, the solution of document 1 includes internal mounting plates 3a and 3b extending along an annular surface inside both rims of tire choppers 2, and external mounting plates 4 located outside of the tire choppers 2 for fastening to the internal mounting plates 3a and 3b bolts 5. A plurality of belts 6 are connected to the grooves 7 of the inner mounting plates 3a and 3b, so that the belts 6 are pulled inward from all sides and secure the tire using a tie 8.

As shown in FIG. 2, according to document 2, the connecting plates 18 are located inside and outside the ends of the end parts 16 of the transverse link 12, cut so that both sides of the tire are V-shaped, and secured by a pair of rivets 20. After that, the chain 10 passes between the connecting plates 18, and the bottom rivet 22 is fixed in the lower center of the connecting plates 18 for placement inside the chain 10.

However, the technical solution of document 1 is very difficult due to too many metal plates 3a, 3b and 4 and has a complex structure and low wear resistance, because the internal mounting plates 3a and 3b require fastening of the belts 6 in the grooves 7, the internal mounting plates 3a and 3b and the external mounting plates 4 must be bolted 5, and the belts 6 are also fastened. In addition, the technical solution of document 2 is simple in construction, but requires a lot of inconvenient work, since the connecting plates 18 are attached to the ends of the end parts 16 and can be easily damaged due to a blow that occurs when the car moves on an uneven road surface, since chain 10 is fixed with rivets 22.

SUMMARY OF THE INVENTION

Accordingly, it is an object of the present invention to provide an anti-skid chain using used tires that can reduce tire and road surface wear, increase durability and reduce material and production costs by using used tires having the same material as tires as friction material .

To solve the above problem, the present invention provides an anti-skid chain using used tires, including a plurality of used tire cushions made by dividing the used tire in a circular direction; external and internal connecting elements for connecting the ends of the exhaust tire cushions at regular intervals, the external and internal connecting elements having the shape of a trapezoid when they are in a stretched state; a plurality of spikes attached to the surface of the used tire pads; external and internal connecting means for separating the external and internal connecting elements from each other, while the external and internal connecting means provide tight contact between the used tire pads and the tire tread surface so that the used tire pads extend across the surface of the tire tread; and chains passing between the cushions of the used tires, the ends of the chains being connected to the external and internal connecting elements, respectively.

Moreover, the stud is a stud in the form of a hexagonal bolt, and the connecting element has a protrusion in the head part, and the stud and the connecting element are placed in the stud entry hole made in the exhaust tire cushion and screwed together. Moreover, the connecting holes of the circuit are made on both sides of the used tire cushion.

Preferred Embodiment

The invention will now be described in detail in accordance with a preferred embodiment with reference to the accompanying drawings. As for links, the same links indicate corresponding parts in several views.

FIG. 3 shows an exploded view of an anti-skid chain using used tires in accordance with a preferred embodiment of the present invention, and FIG. 4 is a view showing a used shape of an anti-skid chain using used tires.

As shown in the drawings, an anti-skid chain using used tires in accordance with this invention includes used tire cushions 100 obtained by uniformly dividing the used tire in a circular direction; external and internal connecting elements 210 and 220 for connecting both ends of the used tire pads, internal connecting means 300 for connecting the internal connecting elements, which are located in the extreme positions, from the internal and external connecting elements 210 and 220 separately from each other and with an adjustable interval; external connecting means 400 for connecting external connecting elements, which are located in extreme positions from the center, separately from each other and with an adjustable interval.

Used tire cushions 100 are fragments of used tires obtained by dividing the used tire uniformly in a circular direction, and both ends of these used tire cushions 100 are connected to the outer and inner connecting elements 210 and 220, respectively.

A plurality of studs 110 are provided on the surfaces of the tire cushions 100 to increase friction on a slippery road surface.

Chain 500 is positioned between used tire cushions 100 to increase the coefficient of friction, and both ends of chain 500 are connected to external and internal connecting elements 210 and 220, respectively. As shown in FIG. 4, the chain 500 can be connected to the external and internal connecting elements 210 and 220 through a pair of rings 510, but it is preferable that the U-rings 520 shown in FIG. 5 be used to reduce the friction noise of the chain 500 and ease of assembly. Moreover, if several of the rings of the outer and inner connecting elements 210 and 220 are cut off before reaching the set interval, and the cut rings are removed to adjust the interval, the inner and outer connecting elements 210 and 220 can be easily used for any type of bus even though that tires of different sizes are used.

As described above, an anti-skid chain using used tires in accordance with this invention can increase wear resistance and braking performance using friction of a metal chain having a relatively large coefficient of friction. Chain 500 can be replaced with friction pads made of urethane.

At the same time, the studs 110 are attached to the surface of the used tire cushions 100 to increase the friction force. In Fig. 4, the spike 110 at the front end is made in the shape of a cone to increase the friction force by effectively pressing it against the road surface. 6a and 6b show another embodiment of the studs. As shown in FIG. 6 a, the stud 110 includes a stud 111 in the form of a hex bolt and a connecting member 112 having a protrusion in its upper part. The stud 111 and the connecting member 112 are placed in the stud hole 101 made in the used tire cushion 100 and screwed together.

As shown in FIGS. 3 and 4, the outer and inner connecting elements 210 and 220 have a metal chain design, take the form of a circle, connecting the ends of the used tire cushions 100, and serve to closely contact the used tire cushions 100 with the tire tread surface.

Fig. 7a shows inner connecting means 300, causing used tire cushions 100, which are connected to trapezoid-shaped external connecting elements 220, in a circle by connecting the ends of the internal connecting elements 210. As shown in Fig. 7b, the internal connecting means 300 include a rack 310 fixed to the end of the inner connecting element 210, a terminal box 320 of the rack fixed to the other end of the inner connecting element 210, a fixing pin 350, Formation in the junction box 320 the rack vertically movable manner, elastically supported by a clamping spring 330 through the middle portion 340 and temper thread engaging rack 310 to limit the movement of the rack 310 in the direction of entry into the junction box rail 320 rail. The inner connector 210 can connect both ends of the inner connector 210 with only one movement when the rail 310 is placed in the junction box 320 of the rail. In addition, with a simple movement, when the user pulls out the rail while pressing on the release part 340, the connection of the ends of the inner connecting element 210 can easily be disconnected. The interval between the ends of the inner connecting element 210 can be adjusted by the depth of the input rail 310 in accordance with the dimensions of the bus.

FIG. 8 shows a perspective view of an external connecting means 400 for connecting both ends of the external connecting element 220 at an adjustable interval. As shown in the drawing, the external connecting means 400 is in the form of a rotary tie and comprises a bolt 410 mounted on the end of the external connecting element 220, and a nut 420 mounted on the other end of the external connecting element 220 for connecting the bolt 411. When the nut rotates, reducing the length, used tire cushions 100 attached to the connecting elements are in close contact with the tire, and an anti-skid chain is mounted on the tire. When the nut rotates in the opposite direction, the snow chain is disconnected.

FIG. 9 shows an anti-skid chain using used tires in accordance with another embodiment of the present invention. In a second embodiment of the present invention, chain 500 is not used in the anti-skid chain, as shown in FIG. The snow chain using the used tires shown in FIG. 9 has worse performance than the snow chain in FIG. 3, but creates less friction noise. Moreover, the connecting holes 120 of the connecting elements are made on both sides of the used tire cushions 100, and the inner connecting element 210 and the external connecting element 220 are placed in the connecting holes 120 of the fastening means, with no space for connecting the chain 500, and thus the anti-skid chain has a very close connection.

The user can install and use a studded tire using used tires in accordance with this invention, as follows.

Firstly, a studded tire using used tires according to the invention is deployed on the floor. The machine wheel is mounted on an anti-skid chain, and the rail 310 and the rail junction box 320 mounted on the ends of the inner connecting element 210 located inside the tire are connected to each other. After that, the bolts 410 and 411 and the nut 420 of the external connecting means 400 mounted on the end of the external connecting element 220 located outside the tire are connected. The length is adjusted by rotating the nut until the tire cushions are in close contact with the tire.

Industrial applicability

As described above, the anti-skid chain using used tires in accordance with this invention has a simple structure, a simple and strong connection between the used tire cushions 100 and the internal and external connecting elements 210 and 220, reduces damage due to impact on an uneven road surface, It has good wear resistance, thus prolonging the service life and reducing the cost of production.
