Apparatus to secure an Automated Teller Machine (ATM) or other structure are disclosed herein. One apparatus includes an arm including an attachment and a lockpin that engages the attachment in an engaged position. The lockpin is configured to prevent the arm from disengaging from the engaged position when a force is applied to the arm. Another apparatus includes an arm including an attachment that prevents rotation of the arm, a lockpin that engages the attachment in an engaged position, and a lock connected to the lockpin to prevent releasing the lockpin from the engaged position. An ATM includes a frame, a gate, and an abutment. The gate includes an arm including an attachment that locks the arm. The abutment includes a lockpin that engages the attachment in an engaged position to prevent the arm from unlocking and a lock connected to the abutment to prevent access to the lockpin.

The solution is directed to a bleacher step access prevention system. The system is configured to be locked in place over a stairway of a retracted bleacher system in order to prevent climbing of the stairway when the bleacher system is in a retracted state. Certain embodiments are configured to accommodate handrails of the bleacher system so that handrails do not have to be removed from the stairwell when the bleacher system is in a retracted state.

A snowboard fixing frame includes a frame body, a fixing assembly, an restricting member and a locking mechanism. The fixing assembly is disposed on the frame body and includes a first rod and a second rod for clamping a snowboard. The restricting member is screwed on the first rod and is rotatable relative to the first rod to adjust a distance between a first restricting portion of the restricting member and the first rod. The restricting member has a first restricting portion. The locking mechanism includes a base, a core member, a locking member and an elastic member. The base is disposed on the second rod and within a first hole. The core member is rotatable with the locking member.

Systems and methods are disclosed that operate a door latch of a door of a heating, ventilation, and/or air conditioning (HVAC) system electronically based on operating a locking engagement device. The locking engagement device may be disposed on an outer portion of a door, the latch may be part of a latching system disposed on an inner portion of the door, and the locking engagement device may transmit a signal indicating that the locking engagement device is in an open or closed position to the latching system via a conductor electronically coupling the locking engagement device and the latching system. In some embodiments, the locking engagement device may transmit a signal indicating that the locking engagement device is in an open or closed position to a controller, which may then instruct the latching system to open or close the latch based on receiving the signal.

Disclosed is a household appliance comprising: a door; a door lock unit equipped with a hook part which is configured to unlock and open the door by moving outward; a motor configured to generate torque by using electricity; a driving gear unit which has a rotary shaft at one end portion and is configured to rotate by receiving the torque from the motor, wherein the one end portion pushes the hook unit to the outside of the door lock unit to open the door when the driving gear unit rotates in one direction; a sensing unit configured to sense the displacement of the other end portion of the driving gear unit when the hook unit moves to the inside of the door lock unit, wherein the other end portion rotates in the opposite direction about the rotary shaft of the driving gear unit; and a control unit configured to control the operation of the motor on the basis of the displacement, sensed by the sensing unit, of the other end of the driving gear unit.

A door module for use with a door system, and applications thereof, are disclosed. The door module comprises a door frame and a door articulated to the door frame, a touchless door module comprising a door motor assembly, a door locking assembly, a control assembly and a power source. The door motor assembly can be configured for displacing the door between an open position and a closed position, responsive to a door opening signal or a door closing signal, respectively, emitted from the control assembly. The locking assembly can be configured for displacing a locking bolt between a locked position at which it is engageable with a locking strike, responsive to a locking signal emitted from the control assembly, and an unlocked position, responsive to an unlocking signal emitted from the control assembly. The control assembly comprises in some embodiments at least one touchless inside sensor, wherein an entrance signal includes a signal received form the at least one inside touchless sensor, resulting in generating a door closing signal and an occupied signal, and an exit signal received by the at least one inside sensor resulting in generating a door opening signal. The control assembly may further comprise a signaling system configured for emitting noticeable door mode indicia responsive to door parameters.

A retail display unit includes a top, a base including a slot and at least one swing door. The at least one swing door is rotatably coupled to the top and the base and includes a main panel and a lower rail engaged with a bottom of the main panel. A door catch is mounted to a back side of the lower rail and has a channel opening that faces downwardly at the base. A latch is rotatable through the slot in the base. When the at least one swing door is in a closed position, the latch is rotated through the slot in the base and positioned in the channel opening of the door catch to lock the at least one swing door.
