Described herein is a cover for mounting to a door handle (30) comprises two parts (10, 12) configured for mutual locking engagement such that when the parts are brought into mutual locking engagement around a door handle (30) at least a portion of the door handle is substantially enclosed within a cavity (16) formed between the two parts (10, 12). At least a portion of at least one of the parts (10, 12) is coated, impregnated, or otherwise provided with a self-cleaning material. Also described is a push plate device comprising a first plate (72) for fixing to a door; and a second plate (71) configured to releasably attach to said first plate in order to form a composite plate structure (70). The second plate (71) is at least partly coated, impregnated, or otherwise provided with a self-cleaning material so that the composite plate structure (70) presents a self-cleaning external surface.

Systems and methods for providing secure locks having redundant access channels are disclosed. In some embodiments of the invention, the smart lock has a hardware processor, a power source, a cylinder, a button that forms a rose knob, and a rose protector. The rose knob and rose protector protect and conceal the hardware processor, the power source, and the cylinder. The rose protector forms an annular groove that slidably interlocks with the rose knob. The rose knob has a plurality of redundant access channels for receiving authentication information. The redundant access channels may include a biometric scanner for receiving biometric information, a passcode keypad for entering a token, or a wireless transceiver for receiving a token from a mobile device and transmitting a response to the mobile device. When the user cannot open the lock through the first redundant access channel, the smart lock is configured to allow access through a second access channel.

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.

The present invention relates to a replacement door handle, and comprises: a connection member which has a groove with a certain depth formed therein so as to be coupled to a door lock; and a handle body which has a corresponding fitting portion formed therein so that the connection member can be fitted into and coupled to the fitting portion. Thereby, the present invention has the following effects: it is possible to replace or change a door handle, which is coupled to a door lock, with or to a variety of designs; it is possible to replace or change the door handle in a convenient and easy manner; and it is possible to use the door handle according to a user's preference or taste.

An insulated door lock assembly including a base member with an aperture for the cylinder of a lock. The base member is configured to be mounted to a door around a hole for the door lock. The inner volume of the base member can be filled with an insulating material. A cover member can be coupled to the base member through a hinge joint. The cover member can be configured to switch between an open state and a closed state. A keyway or a thumb turn of the door lock can be accessible in the open state and the keyway or the thumb turn is covered by the cover member in the closed state. An O-ring can also be provided around a periphery of the base member for sealably engaging the cover member to the base member.

An exemplary knob assembly includes a knob having a circumferential channel, and a deformable ring seated in the circumferential channel. The ring is normally rotatable relative to the knob such that rotation of the ring does not cause a corresponding rotation of the knob. When gripped with a sufficient gripping force, the ring frictionally engages and rotationally couples with the knob, thereby permitting transmission of torque between the ring and the knob. In certain embodiments, the knob assembly may include a detent mechanism operable to selectively couple the ring and the knob. In certain embodiments, the ring may include protrusions operable to engage pockets in the knob to provide for rotational coupling.

Systems and methods for providing secure locks having redundant access channels are disclosed. In some embodiments, the smart lock has a hardware processor, a power source, a cylinder, a button that forms a rose knob, and a rose protector. The rose knob and rose protector protect and conceal the hardware processor, the power source, and the cylinder. The rose protector forms an annular groove that slidabiy interlocks with the rose knob. The rose knob has a plurality of redundant access channels for receiving authentication information, The redundant access channels may include a biometric scanner for receiving biometric information, a passcode keypad for entering a token, or a wireless transceiver for receiving a token from a mobile device and transmitting a response to the mobile device. When the user cannot open the lock through the first redundant access channel, the smart lock is configured to allow access through a second access channel.

The present invention relates to a sanitizing doorknob cover device that sanitizes the device and a hand of a user after each use. The device is primarily comprised of a body having at least one disinfection compound and a first end with an opening. The device functions as a doorknob cover, wherein the disinfection compound is impregnated within the body, such that the compound excretes from the body when the device is grabbed. As a result, the device sanitizes the hand of the user and also the surface of the device each time the device is grabbed.

An arm-receiving door handle and sliding lock system, including an arm-receiving door handle assembly, including an interior plate removably connected to at least a portion of an inner surface of a door to receive a limb of a user thereon, and an exterior plate removably connected to at least a portion of an exterior surface of the door, and a sliding lock assembly, including a knob assembly removably connected to the interior plate to move laterally from unlocked in a first position to at least partially locked in a second position, and from locked in the second position to at least partially unlocked in the first position, a carrier connected to the knob assembly, and a bolt removably connected within at least a portion of the carrier to move from retracted within the carrier to at least partially extended from the carrier in response to moving the knob assembly toward the second position, and move from extended to at least partially retracted within the carrier in response to moving the knob assembly toward the first position.
