Abstract

A gate unit includes a gate mount and a gate coupled to the gate mount for swinging movement between opened and closed positions. A latch assembly is coupled to the gate to lock the gate in the closed position. The gate unit can be mounted in a doorway.

First claim

The invention claimed is:

1. A gate unit for use in a dwelling, the gate unit comprising
a gate mount adapted to be mounted to a portion of the dwelling,
a gate mounted on a portion of the gate mount for swinging movement about a gate-pivot axis between an opened position and a closed position,
wherein the gate mount includes laterally spaced apart vertical side posts and a horizontally extending removable threshold bar that is coupled to the vertical side posts and arranged to interconnect first ends of each of the vertical side posts to provide the gate mount with a U-shape and the gate mount is adapted to be mounted to the portion of the dwelling in a pressure-mounted mode while the threshold bar remains coupled to the vertical side posts using pads that are held under pressure to the portion of the dwelling or in a hardware-mounted mode using hardware that is anchored to the portion of the dwelling after the threshold bar has been decoupled from the vertical side posts,
wherein the gate mount is arranged to assume an upright orientation to cause the threshold bar to lie below the gate and along a floor underlying the gate when the gate unit is placed in a doorway in an interroom environment in the pressure-mounted mode and is arranged to assume an inverted orientation to cause the threshold bar to lie above the gate and in spaced-apart relation to the floor underlying the gate to position the gate to lie between the threshold bar and the floor when the gate unit is placed in a gateway associated with a staircase in a top-of-the-stairs environment, and
wherein the gate mount further includes bar-removal means for coupling and uncoupling the threshold bar to and from the vertical side posts so that the gate mount is retained in the upright orientation in the doorway in the interroom environment in the pressure-mounted mode while the threshold bar is coupled to the vertical side posts and arranged to extend along the floor and the gate mount is retained in the inverted orientation in the gateway in the top-of-the-stairs environment in the hardware-mounted mode before and after decoupling of the threshold bar from the vertical side posts.

2. The gate unit of claim 1 , wherein the threshold bar includes a first segment, a second segment mounted for movement relative to the first segment and to be separated from the first segment, and a segment lock configured to block relative movement of the first and second segments, the first vertical side post is formed to include a first bar-segment storage space sized to receive therein the first segment after the threshold bar has been decoupled from the vertical side posts and the first segment has been separated from the second segment, the second vertical side post is formed to include a second bar-segment storage space sized to receive therein the second segment after the threshold bar has been decoupled from the vertical side posts and the first segment has been separated from the second segment, the first segment is arranged to lie in the bar-storage space formed in the first vertical side post and the second segment is arranged to lie in the bar-storage space formed in the second vertical side post when the gate mount is retained in the inverted orientation in the gateway in the top-of-the-stairs environment.

3. The gate unit of claim 2 , wherein the first bar-segment storage space is formed in an interior region of the first vertical side post and the second bar-segment storage space is formed in an interior region of the second vertical side post.

4. The gate unit of claim 1 , further comprising a latch receiver coupled to a second of the vertical side posts and arranged to extend toward the gate upon movement of the gate to the closed position and wherein the latch assembly includes a latch arranged to swing with the gate about the gate-pivot axis relative to the latch receiver, and wherein the latch includes a lock tab that is arranged to extend into a tab-receiving recess formed in the latch receiver to block swinging movement of the gate about the gate-pivot axis relative to the second of the vertical side posts when the gate occupies the closed position and the latch further includes a leaf spring coupled to the lock tab and configured yieldably to urge the lock tab into the tab-receiving recess formed in the latch receiver upon arrival of the gate at the closed position.

5. The gate unit of claim 4 , wherein the leaf spring is C-shaped and includes a convex side coupled to the lock tab and an opposite concave side arranged to face away from the lock tab toward the gate.

6. The gate unit of claim 4 , wherein the leaf spring includes a first curved leg having a lower end coupled to the lock tab and an opposite upper end confined to slide in an upward direction during withdrawal of the lock tab from the tab-receiving recess formed in the latch receiver and a second curved leg having an upper end coupled to the lock tab and an opposite lower end confined to slide in a downward direction in a direction away from the opposite upper end of the first curved leg during withdrawal of the lock tab from the tab-receiving recess formed in the latch receiver.

7. The gate unit of claim 6 , further comprising a latch-retractor bar constrained to move relative to the second of the vertical side posts to engage the leaf spring to increase a distance between the opposite upper end of the first curved leg and the opposite lower end of the second curved leg to reduce a lateral height of the leaf spring to retract the lock tab laterally from the tab-receiving recess formed in the latch receiver.

8. The gate unit of claim 4 , wherein the leaf spring includes an upper end constrained to move in an upper vertical slot formed in a latch base coupled to the gate to swing with the gate, a lower end constrained to move in a lower vertical slot formed in the latch base to lie between the upper vertical slot and a floor underlying the gate, and a middle portion arranged to lie between the upper and lower ends and coupled to the lock tab.

9. The gate unit of claim 8 , wherein the leaf spring is C-shaped and includes a convex side coupled to the lock tab and an opposite concave side arranged to face away from the lock tab toward the gate.

10. The gate unit of claim 9 , further comprising a latch-retractor bar constrained to move relative to the second of the vertical side posts to engage the convex side of the leaf spring to move the latch from a locked position in which the lock tab extends into the tab-receiving recess formed in the latch receiver when the gate occupies the closed position to an unlocked position wherein the lock tab of the latch is withdrawn from the tab-receiving recess formed in the latch receiver and clear of the latch receiver so as to increase a distance between the upper and lower ends of the leaf spring.

11. The gate unit of claim 4 , further comprising a latch-retractor bar constrained to move relative to the second of the vertical side posts to engage the leaf spring to move the latch relative to the latch receiver to withdraw the lock tab of the latch from the tab-receiving recess formed in the latch receiver and clear of the latch receiver to free the gate to swing about the gate-pivot axis relative to the latch receiver from the closed position to the opened position.

12. The gate unit of claim 11 , wherein the threshold bar includes a first segment, a second segment mounted for movement relative to the first segment and to be separated from the first segment, and a segment lock configured to block relative movement of the first and second segments, the first of the vertical side posts is formed to include a first bar-segment storage space size
