A securing assembly for locking a first section with a second section of an equipment cabinet against hinging movement. The first section can hingedly support a door of the cabinet. The securing assembly can include a knob, with a pocket, and a latch can be coupled to the knob to be rotated by the knob as the securing assembly is rotated between a free orientation and an engaged orientation. In the free orientation, the latch can be disengaged from the second section to permit the first section to hingedly open away from the second section. In the engaged orientation, the latch can be engaged with the second section to lock the first and second sections together and the pocket of the knob can be receive an arm of a lock on the door to lock the door to the first section and lock the securing assembly in the engaged orientation.

A latch assembly for a heating, ventilation, and/or air conditioning (HVAC) enclosure includes a latch having a securement portion configured to couple to an access panel of the enclosure and having a rotational portion. The rotational portion has an engagement feature configured to engage with a tool face or a tool receptacle and the rotational portion has a first retainer adjacent to the engagement feature. The rotational portion is configured to rotate relative to the securement portion such that a locking portion of the rotational portion transitions between a closed configuration and an open configuration. The latch assembly includes a handle accessory having a handle engagement driver configured to engage with the engagement feature of the rotational portion along a first linking axis and having a second retainer configured to couple with the first retainer of the rotational portion along a second linking axis, transverse to the first linking axis.

Discloses is a lock for releasably locking a first component to a second component. The lock includes a driving assembly, configured to be installed on the first component and including a rotatable cylinder housing; a transmission assembly, including a cylinder core which insertable by a key and is in torque-transmission connection with the driving assembly; and a locking assembly, connected with the transmission assembly and having a first position decoupled from the second component and a second position coupled with the second component, wherein the driving assembly can move relative to the first component and drive the locking assembly by means of the movement to complete the locking, and the locking includes: making the locking assembly move to the second position from the first position and be locked there.

A piezoelectric energy harvester system for collecting kinetic energy is provided, wherein the kinetic energy is converted into electrical energy, and wherein at least a portion of the converted electrical energy is utilized to operate a load. The system comprises an energy input portion and an energy harvesting portion. The energy input portion includes an input member configured to be actionable by an outside force. The energy harvesting portion includes a capture member, a sprocket portion, and a piezoelectric energy harvester. The capture member is adapted for receiving mechanical input from the input member. The sprocket portion is disposed for movement with the capture member. The sprocket portion includes at least one radially disposed sprocket actuator configured for making contact with and exciting the piezoelectric energy harvester. The piezoelectric energy harvester is excited by the contact to produce the kinetic energy.

A door knob having a handle shaped as a hockey puck. An illumination device, carried in a face of the handle is selectively illuminated by a control circuit carried within the handle. The control circuit may include a motion sensor to detect a movement of the handle or a motion in front of the device and activate the illumination device. A timer may be connected with the control circuit to deactivate the illumination device after passage of a predetermined time. The door knob may also include a sound emitter coupled to the control circuit to make a sound when the illumination device is activated or in the case without illumination to activate when a movement of the handle is detected. The sounds may be selected to correspond to a sports event, holidays, phrases, sayings or slogans.

A button assembly for a door lock may include a button and a shank. The button may be toollessly couplable to the shank to allow force transmission between the button and the shank. The button may transfer linear force and torque along a longitudinal axis of the button to the shank to allow a state of an associated lock body to be changed.

The present invention detects the movements or the open/close status of a door. After detection it flashes warning lights for approaching people or vehicles. In the primary embodiment, the lighting elements are displaced at the edge of the door panel to clearly indicate the edges. In another embodiment, the lighting element is displaced in a door knob that can warn the people of the opening of the door.

There is disclosed herein a suicide prevention door handle and shower handle wherein each is designed to eliminate any area or structure that could be used to hold a belt, piece of clothing or the like as an aid in committing suicide by hanging. In each case, the safety knob comprises a tapered rose member or faceplate along with a cylinder wedge assembly or handle.

A door handle is configured for mounting to a door, and includes a shell having a front side and a rear side, with the shell defining an internal chamber. A shank extends from the rear side of the shell, and a light source is seated in the internal chamber. A window pattern is positioned on the rear side of the shell such that the light source is operable to project onto the door a light pattern corresponding to the window pattern.

An electric lock includes a housing, a clutch mechanism and a manual control member. The housing is formed with a driving structure having a first inclined surface, a second inclined surface and a bottom surface. The clutch mechanism includes a driving member having a pushing structure, an elastic member arranged on the driving member for abutting against the driving structure, a rotating member having a pushed structure, and a motor for driving the driving member to rotate. The manual control member is connected to the rotating member. When the motor drives the driving member to rotate relative to the driving structure, the elastic member abuts against the first or second inclined surface to push the driving member to move toward the rotating member, so as to allow the pushing structure to abut against the pushed structure, in order to further drive the rotating member to rotate the manual control member.
