Description
CONNECTOR UNIT OF AUTOMOBILE SLIDING PREVENTION FLAG
Technical Field
[1] The present invention relates to a connector unit of an automobile sliding prevention flag, and in particular to a connector unit of an automobile sliding prevention flag which is able to reliably support a rotational force and a torsion force of double wheels, and it is possible to prevent breaking due to a bending stress by a heavy weight for thereby avoiding a loosening phenomenon of a sliding prevention flag and effectively supporting a sliding surface in a stable state.
[2]
Background Art
[3] Generally, it is known that an automobile sliding prevention apparatus is formed of a snow chain engaged to the wheels of an automobile for preventing sliding when a road is frozen due to snow or something. In a high accident possibility area such as in a highway or a damaged road, since it is impossible to engage a chain, a special tire structure such as a snow tire or a spike tire is used.
[4] It is known that the above automobile sliding prevention apparatus generally uses a trapezoid shaped chain with a cable or an integral snow chain connected in a block shape by means of urethane. In the above integral automobile sliding prevention apparatus, a connection ring or a connection cable may be disconnected or broken during an operation of an automobile, so the fixing force of an automobile sliding prevention apparatus may loose, whereby it is very dangerous that an automobile sliding prevention apparatus may be escaped from the wheels or may lose. In this case, it cannot be reused, which reads to a non-economical use of the apparatus.
[5] In addition, it is known that the conventional integral automobile sliding prevention apparatus has a problem that a woman driver or a weak or old person or a disabled person is not easy to engaged or disengage. When a driver meets a sudden snow road or a frozen road, it is impossible to quickly engage the apparatus. Since it is engaged while moving the automobile forward or backward, it is impossible to perform an engaging or disengaging work in a slope road.
[6] The integral automobile sliding prevention apparatus is basically designed to well be adapted to the tires of a common automobile. In case of a large size or truck for transporting passenger or freight, the rear wheels, which transfer driving force, are
formed of double wheel structures (tires are used in double wheel structures for decreasing flat situations by decreasing the total weight applied to each tire), so the integral automobile sliding apparatus has a problem for engaging to a large size automobile having double wheel structures.
[7] The integral automobile sliding apparatus has very complicated problems for engaging or disengaging chains. When the integral automobile sliding apparatus, which is generally made for a passenger car, is engaged to a tire of a truck or a bus, the engaging fixing force and close contact force are decreased even when considering that a double tire width of a truck is narrow or its diameter is small, so an effective driving force and stop force can not be obtained.
[8] In order to overcome the above problems, a new automobile sliding apparatus is disclosed, in which a chain formed in a double wheel of a rear wheel structure of a large size automobile passes through a center (wheel) of a corresponding tire, and is engaged thereto in multiple numbers. However, the above automobile sliding apparatus has the following problems.
[9] Namely, since the conventional automobile sliding apparatus is engaged while passing through a wheel which corresponds to an engaging position surface of a tire on an outer circumference surface of a tire. As the tire rotates, the snot chain rotates along with the same. When a stop force is continuously applied to the tires which rotate at high speed, the intervals cannot be properly maintained, and the weight is concentrated on a snow chain, so the chain might be hurt or be disengaged.
[10] In the conventional automobile sliding apparatus, the weight might be concentrated on one portion, so the engaged portions of the snow chain fixed in multiple numbers may be disengaged, and the braking force may be offset, which might lead to a large accident while decreasing a safety.
[11] Since the conventional automobile sliding prevention apparatus is directed to directly engaging multiple spikes to a double wheel structure without any means for maintaining intervals, when an automobile runs on a non-uniform ground, the multiple snow chains may be concentrated in one direction while being tangled with each other. So, the braking force may be applied in a centrifugal force direction during a cornering work, and the automobile may run in a direction different from the steering direction for thereby causing accidents.
[12] In order to overcome the problems found in the conventional automobile sliding prevention apparatus, the Korean utility model registered number 20-424423 discloses the following features.
[13] figures 1 and 2 show a typical example of the conventional automobile sliding prevention apparatus.
[14] The conventional automobile sliding prevention apparatus 1 comprises a plurality of spikes 2 formed of an insertion end 2a of which its intermediate portion is bent in a V shape for thereby being inserted into a portion between the double wheels, and a close contact end 2b having a protrusion 2b' in a flat shape at both sides of the insertion end 2a while closely contacting with the surface of each tire; a chain 3 which connects the insertion ends 2a of the spikes 2; a connector unit 4 which has multiple length adjusting units 4c for adjusting the length at an opposite side of an engaging hole 4b engaged to the engaging protrusion 2c of the spike 2 engaged to the other end of the chain in a rear side of a ring 4a connected with an end of the chain 3, and an engaging unit 5 which is integrally formed at an end of longitudinal first and second support plates 5a and 5b and includes a hook 5c hooked to the chain 3, a longitudinal tightening end 5d which is disposed between the first and second support plates 5a and 5b, of which its intermediate portion is engaged with a hinge 5d', and a tensional force maintaining end 5e of which its one end is engaged to an inner end of the tightening end 5d with a hinge 5d', and its other end is formed of a tensional force maintaining end 5e having an integral engaging ring.
[15] In the conventional automobile sliding prevention apparatus 1, a V shaped insertion end 2a is inserted into a portion between the double wheels which form a rear wheel structure of a truck or something, and the spikes 3 are arranged along an outer surface of the double wheel structure. So, the apparatus is engaged to the double wheel structure along with an enhanced close contacting force by pulling the chain 3.
[16] An engaging hole 4b of the connector unit 4 engaged at an end of the chain 3 using a ring 4a is engaged at the engaging protrusion 2c of the spike 2, which is positioned at a last portion, in a state that the chain 3 maintains tight.
[17] The tensional force maintaining end 5e of the engaging unit 5 is engaged to the length adjusting unit 4c of the connector unit 4, and the hook 5c is engaged to the chain 3, and the tightening end 5d is folded, and the connector unit 4 and the engaging unit 5 keep a pulled state.
[18] In the conventional automobile sliding prevention apparatus 1 engaged to the double wheel structure, as the automobile runs, the protrusion 2b' supports an icy road or snowy road as the double wheel structure rotates, so the automobile can run without sliding with less noises and vibrations with the helps of thin thickness of the spike 2.
[19] However, the conventional automobile sliding prevention apparatus has a problem
that a close contact unit may be easily hurt due to a distortion phenomenon that the spikes are pulled by means of the rotational force of the double wheels which support a heavy thing.
[20] In addition, as the close contact ends of the spikes are hurt, a lot of damage pieces are produced and spread by means of the rotational force of the double wheels, and such pieces may directly hit the automobile for thereby damaging the automobile. The pieces so produced may hit another automobile which runs beside the automobile with the automobile sliding prevention apparatus for thereby damaging the automobile. As the automobile tries to avoid the pieces, a big traffic accident may oxur.
[21] The connector unit for connecting an automobile sliding prevention flag is made of an integral metallic material. In this case, a chain might be pulled after a spike is first pulled with the help of a rotation of double wheels. So, the connector unit may be broken by means of a sharp torsion force and the vibrations occurring during operation.
[22] In addition, as the connector unit is broken, the automobile sliding prevention flag may be disengaged from the double wheels and at the same time may be wound on the double wheel shaft for thereby causing the automobile to stop or the broken pieces may be spread to the outside of the automobile which leads to hitting another automobile and people, so the accident ratio might increase.
[23] The engaging unit connecting the connector unit and the chain might be loosened by means of a centrifugal force by the rotation of the double wheels or might be broken by means of the same reason as the connector unit, so the automobile sliding prevention apparatus may be loosened.
[24] In the industry, it is urgently needed to develop products which have the features that even when the connector unit is broken by a centrifugal force occurring as the double wheels rotate and the grounding vibration, the broken pieces do not spread, and the automobile sliding prevention apparatus is not escaped from the double wheels for thereby preventing accident of automobile while not influencing another automobiles which runs on the same road and obtaining a desired safety.

[28] It is further another object of the present invention to provide a connector unit of an automobile sliding prevention flag in which connection knuckle pieces are formed in various forms by using only a double type or a main connector unit based on a main connector unit and a sub connector unit, so it is possible to select depending on a speed of an automobile and a sliding characteristic for thereby enhancing applicability.
[29] It is further another object of the present invention to provide a connector unit of an automobile sliding prevention flag which is able to diversify connection methods by forming a hook and an engaging unit having different functions depending on the type of a connection means, so the applicability of the present invention is enhanced.
