A replaceable antimicrobial system for providing a replaceable antimicrobial surface to inhibit and reduce microorganism growth on a surface. The replaceable antimicrobial system generally includes providing an antimicrobial cover, positioning the antimicrobial cover upon an object such as a handle, and securing the antimicrobial cover to the object or removably affixing the antimicrobial cover with adhesive. The securing of the antimicrobial cover is accomplished by heat shrinking the antimicrobial cover upon the object. Alternatively, the securing of the antimicrobial cover is accomplished by an adhesive backing attached to the antimicrobial cover. After a period of time of usage where the antimicrobial cover loses its effectiveness to inhibit microorganisms, the antimicrobial cover is removed and a replaced with a new antimicrobial cover.

A deadbolt covering device includes a first cup that is positionable over a deadbolt of a door to inhibit condensation from collecting within the deadbolt and subsequently rendering the deadbolt inoperable due to freezing. A first cover is movably attached to the first cup to enclose the deadbolt or expose the deadbolt. A second cup is positionable over a doorknob of the door to inhibit condensation from collecting within the doorknob and subsequently rendering the doorknob inoperable due to freezing. A second cover is movably attached to the second cup to enclose the doorknob or expose the doorknob. A member is coupled between the first cup and the second cup such that the first cup and the second cup are spaced apart from each other.

A locking doorknob shroud, configured to be placed over a doorknob, padlock, or similar closing mechanism. The shroud is equipped with two halves which interlock together and seal firmly with a latch. A keyhole, present at a junction of the two halves within the latch, is configured to accept a key, which when turns, unlocks the latch. Alternately, or in addition, a padlock may be used to further secure the latch. A spring assembly disposed in communication with at least one hinge enables the two halves to open about the at least one hinge, providing access to the doorknob when permitted.

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.

Removable, decorative knob covers configured to connect to an existing knob are described. In one embodiment, the decorative knob covers have an elastomeric shaft that is friction fit over an existing, fixed knob. In another embodiment, the decorative knob covers attach to an existing, fixed knob by a clasp.

The present disclosure provides an electro-mechanical lock assembly which illustratively includes a motor, a gear, a driver, a torque member, a housing, and a bezel. The motor is operable upon selective input. The motor is also coupled to the driver to engage both the gear and the housing when the motor is in operation. The bezel is attached to the gear such that when the driver is engaged with both the gear and the housing, manual rotation of the bezel will rotate the housing. The housing is attached to the torque member which is configured to move a latch such that when the bezel rotates the latch is moved.

Embodiments of the present invention comprise a door handle with a handle body connected to a door via a door connector. A slot may be configured in the handle body. The slot may have an open end and an open front that expose an inside of the slot to an exterior of the handle body. One or more slot bars may be configured within the slot. An insert may have one or more slot bar receivers that are each configured to receive one of the one or more slot bars. The insert may be removably configured within the slot. A protruding insert portion may protrude from the slot open end and/or the slot open front. The protruding insert portion may act as a barrier between the handle body and an object to prevent damage to the door handle and/or object.

Embodiments of the present invention comprise a doorknob with a knob portion and a protective portion. A plurality of knob extrusions may extend outwards from a knob outer surface. A plurality of protective portion indentations may extend from a protective portion inner surface towards a protective portion outer surface. The protective portion may be removably or permanently configured over the knob portion whereby the plurality of knob extrusions are configured within the plurality of protective portion indentations to secure the protective portion to the knob portion. The knob extrusions may extend a distance parallel to a knob center axis. Said distance may be less than a corresponding knob length. The knob extrusions may be configured within the protective portion indentations whereby the protective portion is secured to the knob both tangentially and axially.
