290 Burwood Road, Hawthorn, Victoria, Australia S0 0 0 0 0 U0 Cmplete Specification for the invention entitled: 0 4 0 A CAR LOCK The following statement is a full description of this invention, Including the best nethod of performing it known to i TITLE: A CAR LOCK BACKGROUND OF THE INVENTION At present, several kinds of car locks are in use. One kind is removably mounted on the steering wheel and another kind is permanently fixed on the base of the steering wheel. Generally speaking, the former is preferred by most users, mainly because the former can be taken a.vay off the steering wheel, and besides, direct!y forces a thief to give up his intention to steal tlnt, car. But most of the car locks mounted on the steering wheel have an extensible handie for hampering the sheering wheel from being turned around, and a hook for hooking the circular body of the steering wheel. Said hook is S0 commonly made of a tube, which is not so hard to prevent it from being illegally pried off by a thief.
SUMMARY OF THE INVENTION This invention has an object to furnish a car lock having more strength than the conventional ones in preventing it from being broken illegally.
1 5 The car lock in accordance with the present invention is to be mounted on the steering wheel, hampering it from turning around. It comprises a straight handle having a front section with a plurality of circumferential grooves, a lock base having a lengthwise hollow passage and a tube abutting on the passage and a screwed rod abutting on the tube.
A solid hook is fixed at the outer surface of the handle to hook on the steering wheel body and keep it from turning with the help of the screwed rod at the outer end of the lock base screwed around the steering wheel body.
The front grooved section of the handle inserts and moves to and fro in the hollow passage and in the tube of o 4 the lock base to as to adjust the whole length of the handle in relation to the lock base after the screwd rod and the hook have been positioned on the steering wheel, and the lock fixed on the outer surface )f the lock base can be locked with a key, making the dead bolt stick in one of the grooves in the grooved section of the handle, keeping the handle immovable in the steering wheel.
0 0 0 Brief Description Of The Drawings o o0 0 0 Figure 1 is a front view of the car lock in accordance with the present invention.
Figure 2 is a leftside view of the car lock in accordance with the present invention.
Figure 3 is a rightside view of the car lock in accordance with the present invention.
Figure 4 is a cross-sectional on-line 4-4 in Figure 1.
Figure 5 is a perspective view of the car lock of this invention practically locking a steering wheel.
DETAILED DESCRIPTION OF THE INVENTION The car lock according to the present invention comprises a handle 1, and a lock base 2, as its main components.
Referring to Figure 1, the handle 1, has a proper length to fit on the steering wheel, provided with a grooved section 11 at the front. The grooved section 11 is provided with a plurality of circumferential grooves 111 for the dead bolt of a lock 21 to stick in one of them so as to stop the grooved section 11. The handle 1 has two sections of different diameter to reduce the weight. Besides, a hook 12 is made of a solid material and fixed on the outer surface of the handle 1 to hook on the steering wheel body keeping the handle 1 fixedly mounted on the steering wheel.
The tubular lock base 2 is provided with a lengthwise hollow passage for the grooved section 11 of the handle 1 I_ I I I_ I ~I DIIII1~-- lll~---CIIC- PPR- to insert and move to and fro therein, and the lock 21 having the dead bolt 211 is fixed on the outer surface of the lock base 2 such that the dead bolt 211 can stick in any of the circumferential grooves 111 to lock this car lock on the steering wheel. Besides, the lock base 2 is provided with a tube 22 extending out from the end of the hollow passage for the grooved section 1 of the handle 1 to insert and move to and fro therein.
A screwed rod 23 having a 3600 coiled end, secured at the other end to the outer end of the tube 22 in a straight line. The coiled end has an internal diameter a bit larger than the diameter of the steering wheel rim so that said coiled end can be screwed around the wheel rim to mount the lock on it.
1 0 Now how to mount this lock on the steering wheel 3 is to be described.
Referring to Fig. 5, in using this lock, at first the coiled end of the rod 23 is to be fitted on to the rim of the steering wheel 3 by a screwing action. Then the handle 1 is to be pulled down in relation to the lock base 2 to make the hook 12 hook on the steering wheel rim so that the wheel 3 can be caught firmly not to be turned any mnore. Now the lock 21 1 5 is to be locked with the key, making the dead boll 211 stick in one of the circumferential grooves 111, and the locking action of this car lock on the steering wheel 3 is finished.
This lock is deemed to have the following advantages.
1. The coiled end of the rod 23 can effectively prevent the lock from being broken, giving practical safety guarantee.
2. The hook 12 is made of a solid material, not hollow, having strength enough to resist illegal destruction. Even if it should be broken, the other end, the coiled end of the rod 23 would still remain on the steering wheel, impossible to be wrenched straight, keeping the lock on the steering wheel.
