In Mexico December 1, 1950 The present invention relates to a theft-preventing arrangement for motorcars, and more particularly to the arrangement of a brakeactuating manually operable device in the closable trunk compartment of a motorcar.

It is the object of the present invention to provide an arrangement by which a motorcar is protected from being stolen.

It is a further object of the present invention to provide a brake-actuating device in the trunk compartment of a motorcar so that the motorcar may be braked while parked, the brake being releasable only after unlocking of the trunk compartment.

It is another object of the present invention to provide electric alarm means which are actuated when a metal tool is inserted under the door of the trunk compartment for the purpose of forcing the same open.

With, these objects in view the present invention mainly consists in a manually-operable brake-actuating member mounted in a closable trunk compartment of a motorcar movably between a braking position and a releasing position, motion-transmitting means movably mounted on the body of the motorcar and secured at one end thereof to the brake and at the other end thereof to the manually operated brake-actuating member, and locking means mounted also in the trunk compartment for arresting the manually operated brake-actuating member in braking position, so that when the brake-actuating member is in braking position, and the trunk .compartment is closed, moving of the motorcar by unauthorized persons is prevented.

In accordance with a preferred embodiment the present invention mainly consists of a closable trunk compartment in the motor car provided with a door, means insulating the door from the body of the motorcar, a supporting base plate fixedly secured to the inside of the trunk compartment, a brake-actuating disc member rotatably mounted on the base plate and provided with a rack portion on its perimeter, manually operable lever means fixedly secured to the disc member for manually turning the same between a braking position and a releasing position, motion-transmitting cable means movably mounted on the body of the motorcar and secured at one end thereof to the brake and at the other end thereof to the perimeter of the brake-actuating disc so as to be wound up on the same when the brake-actuating disc member is turned by said manually operable lever means whereby the brake is actuated when the brake- 5 Claims.

actuating disc is turned into braking position and released when the brake-actuating disc is turned into releasing position, spring-loaded pawlmeans mounted in the trunk compartment on the base plate and adapted to engage the rack portion on the perimeter of the brakeactuating disc member when the brake-actuating disc member is in braking position, and adapted to be manually released so that the brakeactuating disc member may be turned into releasing position by the manually operable lever means whereby moving of the motor car is prevented when the brake-actuating disc member is in braking position and thetrunk compartment is closed, electric alarm means, including a circuit connected to the electric system of the motor car, and contact means in the circuit of the electric alarm means connected to the body of the motor car on one hand and to the door of the trunk compartment of the motor car on the other hand so as to cause actuation of the electric alarm means when a metal tool is inserted between the door of the trunk compartment and the body.

The novel features which are considered as characteristic for the invention are set forth in'particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings, in which:

- Fig. 1 is a schematic perspective view of the trunk compartment of a motor car provided with a theft-preventing arrangement according to the present invention;

Fig. 2 is a rear view of the motor car;

Fig. 3 is a perspective view of the drivers seat ofa motor car, illustrating a further protective device;

Fig. 4 is a view similar to Fig. and

Fig. 5 is a wiring diagram of the theft-preventing arrangement.

Referring now to the drawings, Fig. 1 shows a supporting base plate I secured to the inside of the trunk compartment of a motor car. A disc member 2 is rotatably mounted on a supporting base plate I secured by screws to the inside of The disc member 2 is provided on approximately one third -.of its perimeter with a rack portion 2' engaged by a spring-loaded pawl 4. A steel cable 3' guided in. a sleeve 5 is fixedly secured, preferably welded, to the perimeter of the disc member 2 so as to be wound upon the smooth perimeter of the same, which may be provided with a groove, when the same is rotated by the manually operated lever 2", which may be welded to disc member 2. The cable 3, 5 passes through a hole 6 in the bottom of a trunk compartment to the under side of the motor car and is securedthereto by clamps 1. The end of cable 3 is connected at IE to the center of a steel cable 8 extending transversely and being secured at I5, IE to cables 9a, 9a leadin to the brakes of the motor car. All fastening screws are preferably secured by welding.

The operation of the arrangement is as follows:

When the manually operable lever 2 is pulled backwards, the disc member is turned, and the steel cable is wound up on the same whereby the hand brake is actuated. The pawl memberdengages the rack portion of the disc member in this braking position. The trunk compartment is now locked and the motor car cannot be'moved by anybody without first opening the trunk compartment. Since the locked trunk compartment can only forcibly be opened by an unauthorized person, such action would require time and would attract attention, whereby theft-of the motor car is prevented. When the'pawl 4 is manually retracted by the operator of the car after the trunk compartment has been unlocked, the rotatable disc member is placed in-a releasing position so that the car may be'used again.

To provide even safer protection of the car, the trunk compartment may be provided with an auxiliary device comprising an electric alarm siren l0 fixedly mounted in the interior of the trunk compartment, or under the hood 'of the car. An insulated electric cable 13 connects the siren with the door I! of thetrunk compartment which is insulated from trunk compartment and the body of the car. Another electric cable II passes through a hole I2 in the bottom of the trunk compartment and connects thesiren to the electric system of the motor car. Sincethe door 20 of the trunk compartment is insulated from thebody of the car 2|, inserting of a metal tool 22, Fig. 2, will result in closing the circuit 'of the siren and cause sounding of an alarm. Consequently, any unauthorized person who attempts to open the locked door of the trunk compartment'by force in order to release the above-described theft-preventing brake-actuating arrangement, would sound the siren and attract attention. As can be seen from the upper portion of Fig. 5, the electric currentfiows from the battry 23 of the car through cable ll, siren [0, cable l3 to the door 20 of the trunk compartment, and further through the portions 21 of the body of the car back to the grounded terminal of the battery23, if the insulation 2| is short-circuited by *a metal tool inserted between door 20 and the body of the car in the manner shown in Fig.

An additional safety'devi'ce is contemplated for preventing theft of articles left on the seat of the car through the window. Fig. 4-shows a cable F provided with a sleeve-shaped metalcontact D which is supported in a support E adjacent to a pivoted window. The end of the sleeve-shaped contact D abuts against the glass panel of the window without contacting the metal frame thereof. Cable F is sufficiently long to be attachedto the window frame and to be withdrawn therefrom when its use is not required, in which caseit is suspended below thedashboardin such -manner that the sleeve-shaped contact does not of the sleeve-shaped contact which is supported by the support E is insulated.

Cable A is an extension of cable F and is connected into the circuit of the alarm siren so that in the event that thieves attempt to force open the Window by exerting a strong pressure on the smaller portion of the window C causing the same to pivot about'its shaft I, the metal frame CI of the window contacts the sleeve-shaped contact and actuates the alarm siren. As is clearly shown in-the lower portion of Fig. 5, electric current'flows from battery 23, cable I l, siren l8, cable A, cable F, the metal contact D, the frame of thewindow C,-pivot pin I, and through the body of the car back to the grounded terminal of the battery 23 when the window is pivoted to the position shown in full lines in Fig. 5, and the contact ED is placed in the support E, the portion E being made of insulating material.

Similar protective arrangements may bepr0- vided for the otherwindows of the car.

Itwill be understood that each of theelements described above, or two or more togethenmay also find a useful application in other typesof theft-preventing arrangements for motor cars differin from the types described above.

While the invention has been illustrated and described as embodied in-a theft-preventing arrangement comprising a brake-actuating device in the trunk compartment of a motor car and electric alarm means actuated by insertion'of a tool under the door of a trunk compartment, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any wayfrom the spirit of the present invention.

Without further analysis, the foregoing'will so fully reveal the gist of the present inventionthat others can by applying current knowledge'readily adapt it for various applications-without omit ting features that, from the standpoint of :prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention, and, therefore, such adaptations shouldandare intended to be comprehended within the meaning and range of equivalenceof the following claims.
