Description

THE TOOL TO PROTECT SLIDING FOR AUTO MOBILE
Technical Field
The present invention relates to a nonskid apparatus in a vehicle, and more particularly, to a nonskid apparatus in a vehicle which allows a driver to mount and detach a nonskid chain through simple manipulation of a switch within the vehicle.
Background Art
Traffic accidents on an icy road or when snow falls, is usually caused due to the slipping of a vehicle.
In order to prevent this, most vehicles have winter-season equipments equipped therein. Further, it is recommended that most vehicles have the winter-season equipments equipped therein on an icy road or a snowy road. A representative one is a chain mounted on a vehicle tire.
Lots of advancement in a vehicle chain technology has been made. Conventionally, the driver has to mount the chains on the tires while slowly moving ahead the vehicle with the chains spread on a road surface. Recently, however, the chains are mounted on the tires at a time. In such nonskid apparatus, however, the driver has to get off the vehicle in order to mount the nonskid apparatus on the tires. If the driver wants to detach the mounted nonskid apparatus, he or she must directly detach the nonskid apparatus from the wheels. Furthermore, there are sometimes cases where the driver does not detach the nonskid apparatus from the vehicle even when the road condition is good out of an icy road or a showy road. This generates noise, causes the road to be destroyed, and makes the driver uncomfortable.
For example, it is dry on a flat road but it is icy on a hill several km ahead. Most drivers will go over the hill without mounting the nonskid apparatus. In this- case, an increase in a danger of an accident will be inevitable.
Therefore,' in order to reduce the traffic accident in winter and reduce inconvenience of a driver depending on mounting and detachment of the nonskid apparatus, there is a need for a new nonskid apparatus that can be automatically mounted or detached through manipulation of a switch within the vehicle.
Disclosure of Invention
Accordingly, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a nonskid apparatus that can be automatically mounted or detached through manipulation of a switch within the vehicle.
To achieve the above objects, according to one aspect of the present invention, there is provided, including an operating pin having a mounting progress pin and a join and release piece that are protruded toward or inserted into the wheel depending on a driver' s manipulation at one side of a brake drum on which a lining for pressing both sides of a brake disk is mounted on; a cam fixed to the wheel and rotated from the direction of the axis to the direction of the tire when the mounting progress pin is protruded; a rotating frame that is rotating along with the cam, the rotating frame having the nonskid stand at its end whereby it is adhered to a portion of the bottom of the tire when the cam is rotated and is returned when an external force is not applied thereto; and a fixing unit for fixing the rotating frame when the nonskid stand is adhered to the bottom of the tire and for releasing the join of the rotating frame when the join and release piece is protruded.

FIG. 7 shows how the rotating frame according to another embodiment of the present invention operates.
Best Mode for Carrying Out the Invention The present invention will now be described in' detail in connection with preferred embodiments with reference to the accompanying drawings, in which like reference numerals are used to identify the same or similar parts.
FIG. la and FIG. lb are front views illustrating mounting and detachment of a nonskid apparatus 2 according to one embodiment of the present invention.
A plurality of rotating frames 21 are mounted on a vehicle' s wheels 11. One end of the rotating frame 21 is mounted at a central portion between an axis 12 of a vehicle tire 1 and an outer circumference of the tire 1. The other end of the rotating frame 21 is mounted at the outer circumference of the tire 1 or near the axis 12 depending on manipulation of a driver.
Therefore, a nonskid stand 22 is mounted to an outer end of the rotating frame 12, serving as a chain. This functions to increase a braking force on an icy road or a shown road.
In winter, the driver can prevent, in advance, most traffic accidents occurring on an icy road by replacing an existing wheel with a wheel 11 on which the nonskid apparatus 2 is mounted. Further, this structure will remove inconvenience of a driver that he or she must directly mount and detach the nonskid apparatus.
Further, those skilled in the art will appreciate that the shape and number of the nonskid stand 22 can be varied so that it can be easily driven on a sand road or a clay road as well as an icy road. Also, it is expected that the nonskid stand 22 may be used for various vehicle-related sports as well as daily life.
FIG. 2a and FIG. 2b are lateral cross-sectional views of the nonskid apparatus according to one embodiment of the present invention.
The nonskid apparatus 2 comprises an operating pin 23 having a mounting progress pin 231 and a join and release piece 232 that are protruded toward or inserted into the wheel 11 depending on a driver' s manipulation at one side of a brake drum 15 on which a lining 14 for pressing both sides of a brake disk 13 is mounted on; a cam 24 fixed to the wheel 11 and rotated from the direction of the axis 12 to the direction of the tire 1 when the mounting progress pin 231 is protruded; a rotating frame 21 that is rotating along with the cam 24, the rotating frame 21 having the nonskid stand 22 at its end whereby it is adhered to a portion of the bottom of the tire 1 when the cam 24 is rotated and is returned when an external force is not applied thereto; and a fixing unit 25 for fixing the rotating frame 21 when the nonskid stand 22 is adhered to the bottom of the tire 1 and for releasing the join of the rotating frame 21 when the join and release piece 232 is protruded.
In other words, in a driving system of the vehicle, it would be preferred that the operating pin 23 is mounted on the brake drum 15 and the nonskid apparatus 2 is operated by the operating pin 23. If a device that can be controlled within the driver' s seat is installed within the axis 12 or the wheel 11 that do not perform a rotating movement, its structure will be complicated. In particular, it is actually impossible to mount the above device on the existing vehicle. For this reason, in the present invention, the operating pin 23 being a starting device is mounted onto the brake drum 15.
Furthermore, a hook 218 is formed at the bottom of the rotating frame 21. The hook 218 is applied with a certain external force by a spring 217. The hook 218 is coupled to a ring unit 17 formed in the wheel.11. The other end of the hook 218 is extended toward the can 24 whereby one end of the hook 218 pushes the end of the cam 24 when the cam 24 rotates, thus making the cam 24 released from the ring unit 17.
Therefore, even when the vehicle is applied with vibration or an external force while it drives, the nonskid apparatus 2 is firmly fixed to the wheel 11 by means of the hook 218.
FIG. 3 is a perspective view illustrating a linkage principle of a cam and a mounting progress pin. The cam 24 is mounted onto the fixing axis 241 and is cooperatively rotated when the mounting progress pin 231 is protruded, wherein the cam 24 rotates about 180° and stops.
In other words, a relative movement direction of the mounting progress pin 231 mounted onto the brake drum that is stopped at the cam 24 is dl. The cam 24 mounted onto the fixing axis 241 is rotated in the direction of d2 since the end of the cam 24 progresses along a tilt surface 242 of the cam 24 when the mounting progress pin 24 1 is protruded. Further, when the tilt surface 242 is formed 180° around the axis 241, the cam is rotated 180° .
FIG. 4 is a partially dismantled perspective view illustrating the structure of a rotating frame 21 and a nonskid stand 22.
The rotating frame 21 includes two or more frames having different sizes, for example, a small-sized frame 211 or a large-sized frame 212. The rotating frame 21 is expanded and contracted as the small-sized frame 211 is inserted into the large-sized frame 212. Further, the rotating frame has a press coil spring 213 built therein. The rotating frame is thus expanded if there is no external force. The nonskid stand 22 is rotatively mounted onto the rotating frame 21 by means of a hinge 214, wherein a spring 215 is installed within the hinge 214 to apply a resilient restoring force in a vertical direction of the rotating frame 21.
In other words, the diameter of the vehicle tire may be varied depending on its type and abrasion. It is thus preferred that the length of the rotating frame 21 is extensible .
In addition, the nonskid stand 22 mounted on the rotating frame 21 must be kept vertical to the rotating frame 21 when there is no external force so that it can be easily mounted on the tire.
FIG. 5 is a conceptual view illustrating the operating principle of a fixing unit. The fixing unit 25 includes axes 251 that are parallel at both sides of the rotating frame 21 when the nonskid stand 22 adheres closely to the bottom of the tire 1, and a fixing piece 252 geared with the axes 251. At this time, a two-folding link 253 is formed at one end of the fixing piece 252 whereby the axes 251 are geared depending on variation in the location of the hinge 254 of the two-folding link 253. Also, a hanging protrusion 255 is formed at the other end of the fixing piece 252 whereby the hanging protrusion 255 is fixed on the top of the rotating frame 21. A join and release piece 257 for releasing the fixing state of the rotating frame 21 as the join and release pin 232 rotates and thus have the axis 256 to rotate is formed at an axis 256 that is formed at one side.
In other words, one end of the hinge 254 of the two- folding link 253 exerts its force downwardly when the rotating frame 21 is unfolded. At this time, the axes 251 rotate symmetrically one another, so that the hanging protrusion 255 is latched to the top of the rotating frame 21 and the rotating frame 21 is fixed.
Also, if the join and release piece 232 is made protruded with the rotating frame 21 fixed, it collides the join and release piece 257 while rotating and has the axis 256 to rotate, so that the join and release piece 232 is released by the fixing piece 252.
Furthermore, in FIG. 4 and FIG. 5, a saw tooth 216 that is right-angled upwardly and oblique downwardly is formed at both sides of the small-sized frame 211 formed at the end of the rotating frame 21. There is further installed a frame fixing piece 258 that is integrally formed with the fixing piece 252, wherein when the nonskid stand 22 adheres closely to the bottom of. the tire 1 and the end of a protrusion is geared with the saw tooth 216 with pressure, the rotating frame 21 is contracted and fixed.
In other words, the rotating frame 21 is made to contract not expand under a given pressure so that the nonskid stand 22 adheres to the tire 1 by maximum, thus reducing shock applied to the device and facilitating braking.
FIG. 6 shows how the nonskid stand operates when a rotating frame is folded. One portion of the rotating frame 21 and the nonskid stand 22 connected by the hinge 214 include a pinion 221. In the event that the rotating frame 21 is folded, a rack 16 is formed at a side near the hinge 214. If the rotating frame 21 is folded, the hinge 214 and the rack 16 are geared to fold the nonskid stand 22.
Therefore, the nonskid stand 22 that always keep vertical to the rotating frame 21 by means of an internal resilient device is seated into the wheel 11 while being folded.
A clean nonskid apparatus 2 can thus be provided.
FIG. 7 shows how the rotating frame according to another embodiment of the present invention operates. The rotating frame includes a first frame 21a geared with the cam of the rotating frame 21, a second frame 21b and inserted into the first frame 21a wherein the second frame 21b is expanded and contracted, and a third frame 21c inserted into the second frame 21b wherein the third frame 21c is expanded and contracted and the end of the third frame 21c is connected to the nonskid stand 22. A guide groove 219 that is inwardly depressed is formed at one side of the third frame 21c. A contraction adjustment cam 26 is rotated as a hinge at an upper end of the second frame 21b. The end of the cam 26 is introduced into the end of the guide groove 219 when being expanded corresponding to the guide groove 219. As the top of the cam 26 is inwardly depressed than the first frame 21a, the protrusion 261 is introduced into the first frame 21a when it is contracted while the end of the protrusion 261 introduced into the guide groove 219 is deviated.
Therefore, the frame that is introduced when the rotating frame 21 is contracted is sequentially performed.
