A retractor assembly for a cylindrical lockset comprises inner and outer retractors. Each of the retractors has a cam engaging surface to convert rotary motion from the inside door handle into linear latch-retracting motion. Inner and outer spindles having retractor activation cams are configured to bear upon cam surfaces of the inner and outer retractors to retract the latch. When the inner door handle is operated, the inner retractor acts directly upon the tailpiece of the latch bolt assembly to retract the latch. When the outer door handle is operated, the outer retractor presses on the inner retractor, causing it to retract the latch. If there is an attack, a blocker assembly engages with members formed in the outer retractor to render the outer retractor inoperative to move into a latch-retracting position without interfering with operation of the inner retractor to move into a latch-retracting position.

A walk-in tub includes a tub frame having a door frame provided in one or more of the walls of the tub frame. The tub further includes a door hingedly connected to the door frame and adapted for movement between an open position into the interior cavity of the tub and a closed position aligned with the door frame. A sealing face is provided on the door frame facing the interior cavity of the tub. A seal is disposed around a perimeter of the door for sealing the door against the sealing face when the door is in the closed position. A latching mechanism on the door is operable between a latching position and an unlatching position and includes a slidable latching pin that is slidable to engage a pin receiver in the latching position when the door is locked and disengage from the pin receiver in the unlatching position when the door is unlocked.

The standard spring retainer for a retract slide is upgraded in three embodiments. In the first embodiment, a first switch mounted on the upgraded spring holder is activated when the latch is retracted (from either side of the lock). In the second embodiment, the first switch is activated when either the latch is retracted or the latch bolt is pushed in by the latch hitting the strikeplate as the door is closing. A spring carrier/switch activator is added to the retract slide that is pushed back by the latch tailpiece. In the third embodiment, two switches monitor up to four conditions—when the door is open, closing, and closed and when the latch is being retracted by the inner or outer handle.

The present disclosure relates to a windows and doors assembly having a ventilation function and a horizontal contact function, and more particularly to a horizontal contact windows and doors assembly for crime prevention and security functions by preventing a window from being open even when the window is slightly open and it is possible to ventilate with the outside air. To achieve the objective of the present disclosure, the windows and doors assembly having a ventilation function and a horizontal contact function includes a window frame, and a windowsill in which the window frame is slidably installed, a handle rotatably installed on the window frame, an engagement unit provided on a lateral surface of the window frame, linked to movement of the handle, and moved in upward and downward directions, an engagement guide provided on the windowsill to face the engagement unit and configured to catch or not catch the engagement unit depending on a position of the engagement unit, and a horizontal moving device provided on at least one of a top surface or a bottom surface of the window frame, linked to the handle, and configured to make the window frame horizontally come into contact with the windowsill or to release horizontal contact depending on movement of the handle, and in this case, when a contact state of the window with respect to the windowsill by the horizontal contact device is released while a catching operation between the engagement unit and the engagement guide is performed, it is possible to ventilate through a gap between the window and the windowsill, the window is restrictly moved to form the gap, and the window is prevented from being freely open.

A safety lock and access key for doors that otherwise need to remain locked comprising a lock body containing a spring biased catch extending from one end of the body to engage in a keep of the door frame, a lever for moving the catch into the body to unlock the door, and a tool for unlocking locked doors.

A dual action latch, having a latch handle, an elongate bolt, a cam, a latch housing, and a biasing device, for installation on one side of door. The latch handle includes a lifting portion and a lever arm. The latch housing has a lever arm aperture through which the lever arm of the latch handle passes and a bolt guide for slidably receiving the elongate bolt. The latch handle is movably attached to the latch housing. With the latch handle moved, the lever arm withdraws the elongate bolt into the latch housing. Independently, when the cam is rotated by a separate handle on the other side the door, the cam plate likewise withdraws the elongate bolt into the latch housing.

A magnetic latch for fastening a closure member to a support. The magnetic latch comprises a latch bolt assembly comprising: a first elongated housing configured to be mounted with its rear side facing either the closure member or the support; a second housing connected to and positioned underneath the first housing, the second housing being rotatable with respect to the first housing around the vertical direction between a first rotational position in which the latch bolt assembly is operable for a right-handed closure member and a second rotational position in which the latch bolt assembly is operable for a left-handed closure member; and a latch bolt mounted in the second housing. The different rotational positions of the second housing allow using a horizontally moveable latch bolt while retaining a symmetrical placement on the closure system irrespective of the handedness of the closure member.

An adjustable latch configured to accommodate different backset lengths. The adjustable latch includes inner and outer housings, at least a portion of the inner housing being structured for axial and rotational displacement within the outer housing as an engagement projection of the inner housing is displaced about an adjustment slot of the outer housing. The apparatus may include a bolt assembly having a bolt rod and a latch bar, the bolt rod having projections that are structured to be adjacent to the latch bar when the bolt rod is at a first rotational position and at first or second axial positions. When the bolt rod is at a second rotational position, the axial positions of the bolt rod and the inner housing relative to at least the latch bar and outer housing, respectively, may be adjusted to adjust the backset setting of the latch.

A lock device that prevents operation of at least one chassis spindle from retracting a latch bolt, and which may provide auto-unlock features. Locking of the lock device can effectuate linear displacement of a slider body from an unlocked position to a locked position. Linear displacement of the slider body is translated into rotational displacement of a cam body that includes, or is coupled to, a locking shaft having a cam protrusion, thereby rotating the cam protrusion. As the cam protrusion rotates, the cam protrusion lifts a locking lug to a locked position wherein the locking lug prevents rotational displacement of a first chassis spindle. When in the locked position, a slider arm of the slider body can be positioned in a retention slot. Subsequent rotable displacement of a second chassis spindle can effectuate displacement of the slider arm from the retention slot and facilitate unlocking of the lock device.
