Description
Background of the Invention
1. Field of the Invention
The present invention relates generally to an automobile security apparatus and more particularly to an automobile security apparatus which fixedly secures the steering wheel of an automobile to the steering housing thereof.
2. Prior Art
The use of automobile security apparatus for locking the steering wheel of an automobile in a fixed position is well known in the prior art as exemplified by numerous patents disclosing automobile security apparatus. U.S. Pat. No. 1,359,729, entitled, Locking Mechanism for Motor Vehicles, issued to J. R. Nichols on Nov. 23, 1920, teaches a locking mechanism comprising a sectional collar, formed in two sections that are adapted to be disposed around and to be fixedly secured to the steering housing of an automobile. The sections are secured together by rivets, which are countersunk into each section thereby impeding their removal. A disadvantage of using rivets to secure the locking mechanism to the steering housing is that these rivets must be cut through in order to remove the locking mechanism from the steering housing.
U.S. Pat. No. 1,709,839, entitled, Means for Securing the Steering Wheels of Motor Vehicles, issued to C. E. Chittenden on Apr. 23, 1923, teaches a locking mechanism wherein the collar attached by mounting bolts to the steering housing of an automobile cannot be removed therefrom when the steering wheel has been locked in place by the locking mechanism. The advantage of Chittenden's automobile security apparatus over the apparatus taught by U.S. Pat. No. 1,359,729, supra, is that the locking mechanism is bolted on the steering housing by mounting bolts and that it cannot be removed once it has locked the steering wheel in a fixed position because the locking mechanism includes a hinged lever which covers the mounting bolts. But this prior art apparatus also has several disadvantages. First, the apparatus is costly to manufacture because its steel components must be formed and machined. Second, when installed in an automobile the apparatus is located in an awkward place for a driver of the automobile because the hinged lever, when the apparatus is unlocked, is too close to the driver's knees.
Summary of the Invention
The present invention is an automobile security apparatus which locked the steering wheel of an automobile to the steering housing thereof in a fixed position. The automobile security apparatus is comprised of a steering wheel lock, a locking assembly, having locking bores for securing the steering wheel lock and connector bores, and a steering housing connector for connecting the locking assembly to the steering housing of the automobile. A bolt in each connector bore assures the locking assembly cannot be disconnected from the steering housing connector once the steering wheel lock has been inserted into the locking assembly because the bolt in each connector bore of the locking assembly is made inaccessible by the insertion of the steering wheel lock. The present invention may be easily installed into or removed from the steering housing of an automobile, once the steering wheel lock has been removed from the locking assembly, by the insertion, or removal, respectively, of four bolts.
It is, therefore, an object of the present invention to provide an inexpensive automobile apparatus for preventing automobile thefts.
It is still another object to provide an automobile security apparatus that is more secure than the prior art automobile security apparatus.
It is yet another object to provide an automobile security apparatus which is simple to install in or remove from an automobile.
The novel features which are believed to be characteristic of the invention both as to its organization and method of operation, together with further objectives and advantages thereof will be better understood from the following description considered in connection with the accompanying drawings in which a presently preferred embodiment of the invention is illustrated by way of example. It is to be expressly understood, however, that the drawing is for the purpose of illustration and description only and is not intended as a definition of the limits of the invention.

Referring now to FIGS. 6 and 7, cam 72 is comprised of generally cylindrical rod 100 having the cross section shown in FIG. 9 and having ends 101 and 102. Cam 72 has axially disposed first bore 103 of uniform diameter at end 101 thereof and axially disposed second bore 104 at end 102 of a larger uniform diameter than that of first bore 103. Second internal surface 105 is internally disposed intermediate to bore 103 and 104. Internal surface 105 has parallel slotted opening 106. Cam 72 has first cam surface 107 disposed perpendicular to the parallel slot opening of slotted opening 106 extending from end 101 to taper 108, which is substantially close to end 102 thereof. Cam 72 has a second cam surface 109 disposed perpendicular to parallel slotted opening 106 extending from taper 108 to end 102 thereof.
Pin assembly 73 shown in FIGS. 5 and 7 comprises plunger 110, helical coil spring 111 and collar 112. Plunger 110 is cylindrical rod 113 of uniform diameter having ends 114 and 115 and having head 116 disposed at end 114 thereof. Collar 112 is shown having ends 121 and 122 and having axially disposed bore 123 of uniform diameter at end 121 and axially disposed bore 124 of a smaller uniform diameter at end 122. Bores 123 and 124 are integrally joined at point 125 intermediate to ends 121 and 122. Collar 112 has notch 126 disposed intermediate to end 122 and point 125 thereof. Helical coil spring 111 is of a uniform diameter smaller than that of bore 123 and larger than that of bore 124. End 115 of plunger 110 is inserted into helical coil spring 111 and both plunger 110 and helical coil spring 111 are inserted into collar 112 to form pin assembly 73.
Lock member mounting element 74 is a hexagonal nut. Lock member mounting element 75 is comprised of rod 130 having ends 131 and 132 and having axially disposed, threaded bore 133. Rod 130 has slot 134 disposed transverse to its longitudinal axis at end 131 thereof.
Referring to FIGS. 6, 7, 8 and 9 locking assembly 13 has lock member 71 inserted into centerline cavity 83 of locking block 70 and secured by lock member mounting element 74. Locking block 70 locking assembly 13 has slotted opening 85 into which threaded rod 98 of lock member 71 is inserted and secured by lock member mounting element 74.
Cam 72 is inserted into first internal bore 86 of locking block 70 and is secured by lock member mounting element 75 threaded onto threaded rod 99 of lock member 71 which has been inserted through parallel slotted opening 106 of cam 72.
Pin assembly 73 is inserted into each end of first aperture 82 and each pin assembly 73 is secured by anchor screws 95 and 96 respectively in each notch 126 thereof and each head 116 thereof contacts the surface of cam 72. End 121 of collar 112 is flush with the curved surface of centerline cavity 83.
The steering housing connector 12 is mounted on the steering housing of an automobile as described above. Lock member 71 is turned so that surfaces 107 and 109 of cam 72 are parallel to side surfaces 77 of locking block 70 thereby allowing plunger 110 of each locking pin assembly 73 to slide closer to each other, thereby exposing bores 89 and 90. Locking block 70 is joined to steering housing connector 12 by connector bolts 137 and 138 inserted into connecting apertures 87 and 88, respectively, of locking block 70 and threaded bores 59 and 60 of second connector element 33, respectively.
Steering wheel lock 11 is placed on the steering wheel of the automobile and ends 18 and 20 thereof are slideably received into locking bores 91 and 92. Lock member 71 rotates can 72 90.degree. causing the curved surfaces of cam 72 to press head 116 of each plunger 110 into bore 123 of each collar 112 thereby pressing end 115 of each plunger 110 into bores 24 and 26 of steering wheel lock 11 and securing steering wheel lock 11. The automobile security apparatus is secure from tampering and disassembly because ends 18 and 20 of steering wheel lock 11 cover connecting bolts 137 and 138 which have been inserted into connecting bores 87 and 88 thereby making then inaccessible because the head of each connecting bolt is beneath an end of steering wheel lock 11.
When steering wheel lock 11 is removed from locking assembly 13, it may be stored in the glove compartment of the automobile. The locking assembly 13 and steering housing connector 12 rest compactly near the steering housing and are located such that they are not close to the driver's knees.
While the invention has been particularly shown and described with reference to preferred embodiment thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit of the invention.
