Abstract

A push button-knob gate latch assembly comprising of: a knob handle, a Center bar (striker); and a gate latch assembly to be mounted to a fence/gate. The push button knob handle is mounted on the exterior of the stationary fence (on the wood post) and includes three round rods and other simple mechanical components which extend through the fence post and connect to the latching device which is secured to the inside of the fence (on the wood post). Pressing the push-button knob moves the center rod and pulls on the closed latch releasing the locking mechanism and freeing the center bar or the striker. Due to its special design, the gate latch locks down on the center bar every time the gate is pushed to a close position and assures a secure closed position.

Claims

1. In combination with a gate latch both mounted on the same side of a hinged gate and a stationary gate post, a latch bar mounted on the said movable gate, and a latch bracket secured on the said stationary gate (wood post) and said post disposed for receiving the latch bar when the gate is in a closed position, a latch lever pivotally mounted to the latch bracket and including a recess dimensioned for partially surrounding the latch bar in a latched position.

17. The latch system of claim 1, wherein said latch assembly and said button knob assembly are adapted for mounting on said gate.

2. A push-button knob assembly mounted on the stationary gate post via a cover plate.

3. The system of claim 2, wherein said push-button knob assembly opens the gate latch when pushed in.

4. The system of claim 2, wherein said button knob assembly screws on to a center rod which extends from the knob to the gate latch on the other side of the gate post.

5. The system of claim 4, wherein the center rod is attached to the gate latch on the other end via a Latch pin.

6. The system of claim 4, wherein the center rod resides inside two tubes which help keep it in place.

7. The system of claim 4, wherein an E-clip and a spring reside on the center rod.

8. The system of claim 7, wherein the E-Clip is mounted on the center rod and on the end of the spring farthest away from the gate latch, and is stationary.

9. The system of claim 8, where in the function of the E-clip is to push the center rod and the spring at the same time toward a forward motion when the gate knob is pushed in order to open the gate latch.

10. The system of claim 7, wherein a spring is mounted on the center rod, at the end of the aluminum rod closest to the gate latch and in front of the E-clip.

11. The system of claim 10, wherein the function of the spring is that once the knob is pushed from the outside of the gate post, the spring along with the e-clip extends the rod outward, which in turn opens up the gate latch releasing the center bar.

12. The system of claim 10. Wherein the function of the spring is that once the knob is released from the outside of the gate post, the spring along with the e-clip contract the rod back to its original position, which in turn closes the gate latch over the center bar, securing it in place.

13. The system of claim 4, wherein the length of the said center rod may be adjustable to fit various sized gate posts.

14. The system of claim 4, wherein the center rod sits in the middle of two other rods which keep it in place.

15. The system of claim 4, wherein the center rod is connected to the gate latch assembly via a pin.

16. The system of claims 11 and 12, wherein the rods, the gate latch assembly, the E-clip, the spring and the pin come pre-assembled for easier functionality.
