Abstract
A pull handle for a fifth wheel utilizes a sliding connection to the operating handle of the locking jaw of the fifth wheel. A retractor spring biases the pull handle inwardly along the sliding connection such that the pull handle assumes a position which will not engage the tires of the tractor with the lock mechanism open, regardless of the adjustment of the suspension of the tractor.
Claims7
In a fifth wheel, for connecting a tractor to a trailer, having a movable locking jaw for securing a king pin within said fifth wheel and an operating handle for moving said jaw to an open position, the improvement comprising:
- (a) a handle member cooperatively attached to said operating handle and displaceable laterally to an open position;
- (b) means for reducing the lateral extension of said handle member subsequent to displacement thereof to an open position including a spring attached to said handle member and resiliently biasing said handle toward a retracted position and means for slidably attaching said handle member to said operating handle including an elongated L-shaped slot formed in said handle member proximal said operating handle and a shoulder bolt engaged within said slot for rigidly affixed to said operating handle.
An apparatus for moving the operating handle of a fifth wheel comprising:
- (a) an elongated, generally flat rectangular handle member having an inner and outer end with an offset portion at said inner end, a pull handle at said outer end and a notch formed in a first side thereof, said handle member being movable to a retracted position and an extended position;
- (b) a handle guide attached to said fifth wheel and encircling said handle member intermediate said inner and outer end, with said handle guide adapted for selective partial insertion within said notch;
- (c) means affixed to said offset portion for biasing said handle member inwardly relative to said handle guide;
- and
- (d) means proximal said inner end for slidably connecting said handle member to an operating handle of said fifth wheel, said operating handle being selectively movable to an open and closed position, such that said biasing means urges said handle member toward a retracted position when said operating handle is in an open position.
The combination with a fifth wheel of the kind having a frame embodying a top plate, there being a depending peripheral flange carried by the frame, intermediate frame members beneath the top plate and depending from the same, together with a king pin jaw, a wedge for locking the jaw in a king pin retaining position and an operating handle for opening and closing said king pin jaw disposed within the frame and selectively movable to an open and closed position the combination further comprising:
- (a) a handle guide mounted beneath said peripheral flange and affixed thereto;
- (b) a handle member disposed within said handle guide and having an inner and outer end with said outer end adopted for manual grasping and extending beyond said peripheral flange;
- (c) means for biasing said handle member inwardly toward a retracted position relative to said when said operating handle is in an open position;
- and
- (d) means for slidably connecting said handle member to said operating handle such that said biasing means urges said handle member into a semi-semi-retracted position when said operating handle is in an open position including an elongated L-shaped slot formed in said handle member proximal said operating handle and a shoulder bolt engaged within said slot and rigidly affixed to said operating handle.
