[56] References Cited 4 Claims, 3 Drawing Figures UNITED STATES PATENTS 2,126,234 8/1938 Weber .Z4/02 PATENTEDAPR 4 I972 INVENTOR William L3ilmore BY 4%94 A n m v CABLE CONTROL RETRACTION-LOCKUP DEVICE BACKGROUND OF THE INVENTION Push-pull cables typically include an operating handle connected to the end remote from the device to be operated. Actuation of the device is effected by pushing or pulling the handle. After actuation of the device, the control handle is reset by moving it to its original position. In some a spring may be for automatically returning the control handle to its original position. For reasons of safety, it may be desirable to lock the control handle against accidental movement which would cause actuation of the device to which the cable is connected. For example, in the automotive industry, present interest in safety makes it desirable to prevent accidental opening of the front hood of the automobile by the driver accidentally pulling on the hood release control handle mounted on the dash panel. Typically constructed hood release controls as now included on automobiles do not provide for automatic locking of the hood release control against accidental pulling by the car occupant.
SUMMARY OF THE INVENTION In accordance with the teachings of the present invention, the conventional push-pull control handle for operating the hood of the automobile is provided with a Kurt J. New retraction-lockup device for automatically returning the control handle to a retracted position after the hood release is purposely operated. In addition, the control handle is automatically retained in a locked position requiring preliminary rotation before it can be pulled to actuate the hood release mechanism.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side view of the push-pull cable control device of the present invention;
FIG. 2 is a view similar to FIG. 1 showing the cable in actuating position; and
FIG. 3 is a partial cross-sectional view of the control device showing the connections of the individual parts.
DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in the drawings, a conventionally constructed cable 1 comprised of an inner movable element 2 and an outer flexible conduit 3 is connected at one end to a support housing 4. The other end of the inner element of the cable has a coupling member 3' fixed to it for connection to the hood release mechanism of the automobile. The support housing 4 for the cable is adapted to be mounted on the dash panel 5 of an automobile in the manner shown.
The end of the inner movable element 2 of the push-pull cable extending into the housing 4 is connected to one end of a coupling rod 6. The other end of the rod extends out through the other end of the housing and has attached thereto an operating handle 7. For controlling push-pull movement of the cable, the housing is provided with a guidance slot 8 having a first section 9 extending longitudinally of the cable and a second section 10 extending laterally of the cable. Cooperating with this slot is a lock pin member 11 which is connected at one end to the coupling rod intermediate its ends and extends outwardly through the slot 8. Finally, a spring 12 is provided for controlling the movement of the cable relative to the housing. This spring is coiled about the housing with one end 13 connected to the lock pin and its other end 14 connected to the housing. The spring is a combined torsion and compression spring which normally urges the lock pin along the first section 9 of the slot 8 to the end which meets with the lateral section 10. The torsion of the spring operates to urge the pin 1 1 into the laterally extending section.
In operation, the push-pull cable is actuated to release the hood latch by pulling on the handle against the force of the spring. Before such pulling can be effected, however, the handle must be rotated in 'a counterclockwise direction and against the torsion forces of the spring 12 to align the lock pin 11 with the longitudinal section 9 of the guidance slot. Upon release of the handle, the spring will automatically expand axially to move the cable and control handle to a retracted position. Once the lock pin reaches the end of the longitudinal section 9 of the guidance slot, the torsion in the spring will automatically move the pin 11 into the lateral section 10. This, in turn, will lock the handle against subsequent accidental pulling.
