Assignee:

Emhart Industries, Inc. - Farmington CT

International Classification:

E05B 5500

US Classification:

70467

Abstract:

A lockset for a door comprising a latchbolt assembly including a bolt movable between a fully extended deadbolt locked position, and a retracted position. A spindle extends through the latch assembly in a direction transverse of the direction of movement of the bolt. Rotation of the spindle results in the bolt moving between its positions. The lockset further includes an operating assembly comprising a hand operator having a lock therein, a first plate mounted for linear movement in a direction transverse of the axis of the spindle, an actuating member connected to the hand operator for moving the first plate, a second plate having linear movement transverse to the axis of the spindle and adapted to be moved by the first plate, and rotatable drive member attached to the spindle and adapted to be rotated by the second plate. The second plate is movable between bolt retracted, and fully extended positions. A detent member engages the second plate when the locking member is unlocked for preventing the second plate from moving between its bolt unlocked and bolt fully extended positions.

Assignee:

Emhart Industries, Inc. - Farmington CT

International Classification:

E05C 1502

US Classification:

292 92

Abstract:

An exit device for a door includes a rear channel member, a latch bolt assembly at one end of the channel member, a pair of spaced rails mounted in the rear channel member, with the channel member including two sets of opposed longitudinally extending grooves in its interior forming tracks for the rails. The rails are mounted in the tracks. A path bar includes a portion extending outwardly of the channel member. At least one connecting link is pivotably attached at one end to the rails and pivotably attached at the other end to the push bar for mounting the push bar in the channel for movement between a retracted position and a depressed position. The push bar has tapered end portions tapering outwardly toward the latch bolt assembly. The exit device further includes a cover including an end portion adjacent the push bar and having a taper complementary to the taper on the adjacent end of the push bar. The exit device further includes a skirt member mounted in the rear channel member and extending from the push bar to the end of the rear channel member opposite to the latch bolt assembly.

Assignee:

Emhart Industries, Inc. - Farmington CT

International Classification:

E05B 6510

US Classification:

70 92

Abstract:

An exit device including a latch bolt and an action lever. The action lever includes a cam lever pivotably connected thereto and having a first portion engaging a locking member and a second portion engaging the latch bolt the cause the retraction thereof as the action lever is pivoted into its open position when a locking member is in an unlocked position. When the locking member is in the locked position, the first portion of the cam lever is free of engagement of the locking member and a second portion is free to cam about the latch bolt upon pivoting of the action lever into its open position whereby the latch bolt is not retracted.

Appl. No.:

6/940198

Inventors:

Theodore H. Miller - New Britain CT

Assignee:

Emhart Industries, Inc. - Farmington CT

International Classification:

E05C 2100

US Classification:

292 92

Abstract:

An exit device primarily designed for outwardly opening doors comprises a rigid plate member having mounted thereon a latch-bolt assembly anchored to a door member and a strike assembly mounted on a door frame member in operative association with the latch-bolt assembly, wherein the plate member includes projections positioned to be on each side of the latch bolt of the latch-bolt assembly, and wherein the strike assembly includes recesses for receiving such projections. The recesses in the strike assembly are configured in relation to the projections to allow limited vertical movement of the projections within the recesses. When the device is subjected to a major force such as in a fire the projections will restrict linear growth of the frame member in the latch area by engagement of the projections, with the walls of the recesses thereby preventing excessive strain from occurring on the latch bolt which can lead to disengagement of a latch bolt from the strike. Additionally, the projections limit lateral movement of the strike and door frame member away from the latch-bolt assembly and limit inward movement of the strike and door frame member toward the latch assembly. The exit device, which can be used on single or double doors, is particularly suitable for use on a fire or emergency door.

Assignee:

Emhart Industries, Inc. - Farmington CT

International Classification:

E05C 904
E05C 1502

US Classification:

292 21

Abstract:

An emergency exit device mounted on the inner face of an outwardly opening door includes top and bottom latches mounted near the beveled or free side edge of the door and connected to an operating unit by vertically extending rods. The operating unit is at all times operable to release the latches in response to pressure applied in a door opening direction to a push bar which extends across the inner face. The latches are released from the outer side of the door by a rotary operator operably connected to the operating unit and having a conventional backset. The vertical axis of the rods is horizontally offset from the axis of the rotary operator in the direction of the free side edge of the door.

Appl. No.:

Inventors:

Theodore H. Miller - New Britain CT

Assignee:

Emhart Industries Inc. - Farmington CT

International Classification:

E05B 6510

US Classification:

292 92

Abstract:

An electrically operated exit device comprises a low powered dogging assembly for a pushbar and an electrical actuator for a latch bolt. A latching bracket is attached to the pushbar for movement inwardly and outwardly along a path. A dogging plate of the dogging element is pivotally moveable between a retracted position out of the path of the latching element and an extended position in the path of the latching element. The dogging plate is spring biased toward the extended position and has a protruding shoulder. When the dogging plate is extended and the pushbar moved inward manually, the latching bracket strikes the dogging plate, retracts it slightly against the force of the spring bias and then continues slightly beyond the shoulder of the dogging plate. Then, the doggin plate again extends fully under the influence of the spring bias such that a bearing surface on the far side of the shoulder catches the latching bracket and thereby dogs the pushbar. The electric latch bolt actuator is coupled to a deadbolt by a first linkage assembly and to the latch bolt by the second linkage assembly and simultaneously manipulates the deadbolt and latch bolt to free the door.
