Trailer coupler having an integrated lock
View Patent ↗The present invention provides a trailer coupler having an integrated locking device attached to the handle or the coupler body. The handle of the trailer coupler moves from a first position where the hitch ball is insertable to a second position where the hitch ball is prevented from insertion. The locking device having a locking pin that is insertable into the aperture of the handle to prevent movement of the handle from the second position to the first position.
1. A trailer coupler comprising:
a coupler body;
a ball socket sized and shaped to receive a hitch ball, the ball socket located within the coupler body;
a handle connected to the ball socket, the handle movable to a first position where the hitch ball is insertable into the ball socket and to a second position where the hitch ball is prevented from insertion into the ball socket;
a support member fixed to the coupler body, at least a portion of the support member being positioned within the handle when the handle is in the second position;
a locking device permanently attached to the handle, the locking device preventing movement of the handle from the second position to the first position.
2. The trailer coupler of claim 1 wherein the first position is adjacent to the coupler body.
3. The trailer coupler of claim 1 wherein the locking device includes a locking pin extendable to prevent movement of the handle from the second position to the first position.
4. The trailer coupler of claim 3 wherein the locking pin extends and retracts from an aperture in the handle.
5. The trailer coupler of claim 4 wherein the locking device includes a locking mechanism to prevent unauthorized movement of the locking pin.
6. The trailer coupler of claim 5 wherein the locking mechanism includes a push button that is depressed to extend the locking pin into the aperture of the handle.
7. The trailer coupler of claim 6 wherein the push button includes the locking pin that is retraced by use of a key with the push button.
8. The trailer coupler of claim 4 wherein the locking pin retracts into a housing of the locking device to allow movement of the handle.
9. The trailer coupler of claim 1 wherein the locking device is welded to the handle.
10. The trailer coupler of claim 1 wherein the locking device is integrally formed with the handle.
11. The trailer coupler of claim 1 wherein the locking device is permanently attached to the body of the trailer coupler.
12. The trailer coupler of claim 1 wherein the support member includes an aperture aligned with an aperture in the handle when the handle is at the second position.
13. The trailer coupler of claim 12 wherein the locking device has a locking pin that is extendable through the aperture of the handle and the aperture of the support member to prevent movement of the handle from the second position to the first position.
14. A trailer coupler securable to a hitch ball of a towing vehicle comprising:
a ball socket located within a coupler body;
a handle operably connected to the ball socket, the handle movable from a first position where the hitch ball is insertable and removable from the ball socket to a second position where the hitch ball is prevented from insertion or removal from the ball socket, the handle having an aperture;
a support member permanently attached to the coupler body, wherein said support member is located above the coupler body and adjacent the handle, the support member having an aperture aligned with the aperture of the handle when the handle is at the second position; and
a locking device attached to the handle, the locking device having a locking pin extendable into the aperture of the handle and the aperture of the support member to prevent the handle from moving from the second position to the first position.
15. The trailer coupler of claim 14 wherein the locking device includes a locking mechanism to prevent unauthorized movement of the locking pin.
16. The trailer coupler of claim 15 wherein the locking mechanism includes a housing, the locking pin retractable into the housing and extendable from the housing.
17. A method of securing a trailer coupler from unauthorized connection to a hitch ball comprising:
providing a coupler body;
providing a ball socket on the coupler body;
connecting a handle to the ball socket that is movable from a first position to a second position, the second position preventing insertion of the hitch ball at the second position, the handle having an aperture;
aligning the handle aperture with an aperture in a support member attached to the coupler body; and
permanently attaching a locking device to the handle, the locking device having a locking pin extendable and retractable into the aperture of the handle and the support member aperture.
18. The method of claim 17 further comprising the step of:
incorporating a locking mechanism into the locking device to prevent unauthorized movement of the locking pin.
19. The method of claim 18 wherein the handle is freely movable if the locking pin is retracted from the aperture of the handle.
20. The method of claim 18 wherein the locking mechanism includes a push button to extend the locking pin into the aperture of the handle, wherein insertion of a key into the push button retracts the locking pin from the handle.
