Provided herein is a self-contained, self-disinfecting device which automatically disinfects a surface of the device using internally-generated or applied UV (Ultraviolet) light. The device may be a door handle, push plate, light switch, shopping cart, or the like.

A latch mechanism for a bathroom stall door includes: a sliding latch having an engagement portion and a user contact portion, the user contact portion having a latch movement section and a door movement section; a door bracket configured to attach to a door and that restrains movement of the sliding latch relative to the door, the movement being restrained to a sliding movement; and a latch catcher configured to attach to a frame adjacent to the door, the latch catcher receiving the engagement portion of the sliding latch when the sliding latch is in a latched position. The latch movement section is configured to translate movement of the user to movement of the sliding latch between an unlatched position and the latched position, and the door movement section is configured to translate movement of the user to movement of the door between an open position and a closed position.

A hands-free door latch allows closing the door and latching the door shut without a person using the person's hands, and further allows unlatching the latch without the person using the person's hands. In one preferred embodiment, shutting the door causes the latch to close by the force of gravity. In some embodiments, the latch can be unlatched with a person's foot. In other embodiments, the latch can be unlatched with a person's arm or elbow. The hands-free door latch allows a person to latch and unlatch a door without hands, thereby decreasing the likelihood of exposing a person's hands to germs left by someone else.

A system, device, and method render germ-free door handles in a commercial environment by sanitizing such door handles through the dispensing of a germicide, such as a disinfectant, antibacterial solution, or cleansing agent, onto the door handles at controlled intervals. The controlled intervals are determined by a set of controls which establish a series of settings corresponding to a different amount of time that a valve member is in an operating state.

Various implementations of the invention are directed toward a sanitizing door handle and/or components of such sanitizing door handle. Some implementations of the invention are directed toward a manual sanitizing door handle while some implementations of the invention are directed toward an auto-sanitizing door handle. According to some implementations of the invention, a sanitizing fluid is dispensed directly onto an exterior surface of the sanitizing door handle in connection with an operation of the door handle to sanitize the door handle. According to some implementations of the invention, a sanitizing fluid is dispensed directly onto a user's hand(s) in connection with an operation of the door handle to sanitize the user's hand(s).

An apparatus for efficiently transferring electric power to doors from a door jamb in order to energize door-associated electrical devices, which includes a door for entering and exiting a room, a stationary door electric power transfer bar affixed to the door and a door jamb associated with the door. A striker plate is provided for the door jamb and there is a retractable energized electric power transfer member in the striker plate, along with a power supply for electrical devices associated with the door which would require electrical power.

Various implementations of the invention are directed toward a sanitizing door handle and/or components of such sanitizing door handle that sanitizes the door handle during use. Various implementations of the invention are directed toward a gravity-fed sanitizing door handle and/or components of such sanitizing door handle. Various implementations of the invention are directed to a hand sanitizing dispenser that dispenses a fluid, such as a sanitizing fluid, onto hand(s) of a user when the user operates or otherwise engages a door handle, such as, but not limited to, the sanitizing door handles discussed above. In some implementations of the invention, the fluid is dispensed directly onto the hands of the user. In some implementations of the invention, the fluid is dispensed through dispensers and onto the hands of the user through contact with the dispensers. In some implementations of the invention, the fluid is dispensed onto the exterior of the sanitizing door handle and is subsequently passed onto the hands of the user through contact with the sanitizing door handle.

A door handle sanitizing apparatus may include a posterior wall configured to be disposed anterior of and substantially parallel to a door surface and having an inner surface, an arch portion extending in an anterior direction from the posterior wall, the arch portion having an anterior end and an inner surface, a first sanitizing agent source disposed on the posterior wall, and a second sanitizing agent source disposed on the inner surface of the arch portion.

Sterilization assemblies and self-sterilizing systems using the same include a support housing, a plurality of light-emitting diodes coupled to the support housing to selectively emit UV radiation to sterilize contaminants on a door handle, and a controller coupled to a power source and being configured to operate the plurality of light-emitting diodes by selectively providing power to the plurality of light-emitting diodes based on motion detection within a proximity of the door handle.

A sterilization device for improving a disinfection effect includes: a main body, including a first surface, a second surface opposite to the first surface, and an accommodating hole, two sides of the main body respectively configured with a through hole, and the through holes in communication with the accommodating hole; a sanitizing lamp, configured on the second surface of the main body, the sanitizing lamp including a lighting element, sensor element, control element and power element; and a fixing member, passed through the through holes and accommodating hole of the main body. Taking a door handle as an example, the main body is passed through with the door handle through the accommodation hole, and the fixing member is then inserted through the through holes and accommodating hole, thereby fixing the main body on the door handle. Thus, the sanitizing lamp emits light to disinfect the door handle.
