Abstract

A quick release lock turnbuckle includes a socket slideable axially over a turnbuckle connecting between two threaded rods at a desired end-to-end spacing. The socket has a multi-sided interior cross section engaging a multi-sided exterior cross section of the turnbuckle, and also engaging a radially extending feature on one of the threaded rods to prevent rotation of the turnbuckle in the locked position. The socket is slideable axially off the turnbuckle to allow rotation of the turnbuckle in the unlocked position to change the desired end-to-end spacing between the two threaded rods.

First claim

The invention claimed is:

1. A quick release lock turnbuckle, comprising:
a first rod and a second rod in a zero turn mower steering linkage, the first rod and the second rod threaded into a first end and a second end of a turnbuckle; the turnbuckle having an outer multi-sided cross section; and
a socket having an internal passage with a multi-sided cross section that is slideable over the turnbuckle to a locked position preventing rotation of the turnbuckle, and slideable off the turnbuckle to an unlocked position allowing rotation of the turnbuckle to adjust how far the first rod and the second rod are threaded into the first end and the second end of the turnbuckle;
a keyed feature extending radially outwardly from the first rod and engaging a first side and a second side of the internal passage while allowing the socket to move axially relative to the first rod.

2. The quick release lock turnbuckle of claim 1 further comprising a compression spring around the first rod biasing the socket to the locked position.

3. The quick release lock turnbuckle of claim 1 further comprising a stop extending radially outwardly from the turnbuckle and wherein the socket abuts the stop when it reaches the locked position.

4. A quick release lock turnbuckle, comprising:
a turnbuckle having a multi-sided exterior cross section and a pair of ends engaging a pair of rods end to end; one of the pair of rods having a radially extending feature;
a socket slideable over one of the ends of the turnbuckle and having a multi-sided internal bore engaging the radially extending feature in a locked position while allowing the socket to move axially relative to the one rod, and slideable off the end of the turnbuckle in an unlocked position.

5. The quick release lock turnbuckle of claim 4 wherein the turnbuckle has internally threaded first and second ends engaging the pair of rods.

6. The quick release lock turnbuckle of claim 4 further comprising a coil spring urging the socket to the locked position.

7. The quick release lock turnbuckle of claim 4 wherein the pair of rods are part of a zero turn mower steering linkage.

8. A quick release lock turnbuckle, comprising:
a socket slideable axially over a turnbuckle connecting between a first threaded rod and a second threaded rod at a desired end-to-end spacing; the socket having a multi-sided interior cross section engaging a multi-sided exterior cross section of the turnbuckle and engaging a radially extending feature on one of the threaded rods to prevent rotation of the turnbuckle in the locked position; the socket being slideable axially off the turnbuckle to allow rotation of the turnbuckle in the unlocked position to change the desired end-to-end spacing between the first threaded rod and the second threaded rod.

9. The quick release turnbuckle of claim 8 further comprising a spring urging the socket to the locked position.

10. The quick release lock turnbuckle of claim 8 wherein the multi-sided interior cross section and exterior cross section are hexagonal.

11. The quick release lock turnbuckle of claim 8 wherein the threaded rods are in a steering linkage of a zero turn mower.
