Abstract: Systems, devices, and methods are provided herein for the handless operation of a door. Illustrative examples of a system disclosed herein include a user interaction assembly configured to be disposed at a bottom edge of the door, the user interaction assembly configured to generate a signal, a push-lock assembly configured to attach to a door handle external to a mounting rose of the door handle, and the push-lock assembly configured to receive the signal from the user interaction assembly and translate the signal into rotational movement configured to operate the door handle.

Abstract: Systems, devices, and methods are provided herein for handless operation of a door. For example, a system is disclosed having a foot pedal assembly configured to be disposed at a bottom edge of the door, the foot pedal assembly configured to generate a signal, and a push-lock assembly configured to attach to a door handle external to a mounting rose of the door handle, the push-lock assembly configured to receive the signal from the foot pedal assembly and translate the signal into rotational movement configured to operate the door handle.

Abstract: A clip is provided for a compressive restraining engagement of two sides with material such as money placed therebetween. The clip employs a serpentine configuration of a wire-like member to form a pair of diagonal crossing members communicating between two parallel sidewalls formed by distal ends of the member. A continuous parallel positioning of the contact surfaces of both sidewalls once engaged with material therebetween, enhances the biased engagement of the material. Planar sidewall sections may be engaged to the member sidewalls to enhance the contact with material therebetween and to enhance the ornamental aspects of the device.
