Gate latch
A gate latch assembly comprising: (a) a biased latchbolt repositionable between a retracted position and an extended position; (b) a latchbolt catch to receive the latchbolt; and (c) a two-stage mechanism for repositioning the latchbolt from the extended position to the retracted position including a first stage mechanism having a clutch for selectively engaging the latchbolt, and a second stage mechanism for repositioning the latchbolt from the extended position to the retracted position while the clutch is engaged, where the second stage mechanism is repositionable independent of the latchbolt when the clutch is not engaged.
1. A gate latch assembly comprising:
a biased latchbolt moved between a retracted position and an extended position;
a latchbolt catch to receive the latchbolt; and
a two-stage mechanism for repositioning the latchbolt from the extended position to the retracted position, the two-stage mechanism comprising a button structure, a clutch member having, first and second contacting surfaces, a biasing member, and an inner operating member having a follower therein and moved between a non-operating position and an operating position;
wherein the first stage the mechanism is operated by pushing the button structure to engage the first contacting surface of the clutch member with the latch bolt and, the second stage of the mechanism is operated by moving the inner operating member toward the operating position so as to allow the follower to move along the second contacting member of the clutch member to allow the latch bolt to be retracted; wherein when the inner operating member is returned to the non-operating position, the first contacting surface of the clutch member is biased to disengage the latch bolt.
2. The gate latch assembly of claim 1 , wherein the inner operating member comprises first and second covering members partially covering the clutch member; wherein the second covering includes the follower.
3. The gate latch assembly of claim 2 , wherein;
the first covering includes complementary panels majorily enclosing the two-stage mechanism; and
the complementary panels cooperate to form guides to guide the movement of the latchbolt between the extended position and the retracted position.
4. The gate latch assembly of claim 2 , wherein:
the latchbolt includes a repositionable pin traversing along a pin guide;
the pin includes a projection or a cavity that engages the pin guide to selectively reposition the pin when the pin guide is repositioned; and
the pin guide is selectively engaged by the clutch.
5. The gate latch assembly of claim 4 , wherein:
the pin includes a proximal projection;
the pin includes alignment features that interact with corresponding features of the first coveting to guide traversal of the pin;
the first covering includes an orifice though which the proximal projection extends in the extended position; and
the second covering includes an office through which the proximal projection extends in the extended position.
6. The gate latch assembly of claim 1 , wherein:
the first contacting surface of the clutch member includes two pivotally mounted arms adapted to be moved by operation of the button structure, each arm includes a detent to engage a corresponding cavity of the latchbolt when the button structure is pushed, and the arms are biased apart from one another to inhibit engagement of each detent with its corresponding cavity of the latchbolt when the button structure is released.
7. A repositionable barrier comprising:
a gate frame;
a repositionable gate door cooperating with the gate frame to provide a barrier across an area having a width and a height cooperatively defined by the gate frame and gate door when the gate door is in a closed position; and
a gate latch assembly comprising:
a biased latchbolt moved between a retracted position and an extended position;
a latchbolt catch to receive the latchbolt and
a two-stage mechanism for repositioning the latchbolt from the extended position to the retracted position, the two-stage mechanism comprising a button structure, a clutch member having first and second contacting surfaces, a biasing member and an inner operating member having a follower therein and moved between a non-operating position and an operating position;
wherein the first stage of the mechanism is operated by pushing the button structure to engage the first contacting surface of the clutch member with the latch bolt and the second stage of the mechanism is operated by moving the inner operating member toward the operating position so as to allow the follower to move along the second contacting member of the clutch member to allow the latch bolt to be retracted; wherein, when the inner operating member is returned to the non-operating position the first contacting surface of the clutch member is biased to disengage the latch bolt.
8. The gate latch assembly of claim 7 , wherein the inner operating member comprises first and second covering members partially covering the clutch member; wherein the second covering includes the follower.
