Abstract: A device facilitating operation of a doorknob, comprising a tubular body member having a continuous wall with an outer gripping surface and an inner surface defining bore adapted for receiving the doorknob. A plurality of resiliently deformable projections extend inwardly from the inner surface of the wall. A distance between opposing projections before installation of the device on the doorknob is smaller than a cross dimension of the knob. Each projection has a pair of spaced end portions formed integrally with the inner surface of the wall. The outer gripping surface of the continuous wall includes a generally curved section between each pair of spaced end portions before the device is installed on the knob. Deformation of the projections upon installation of the device on the knob causes the spaced end portions of each projection to spread apart and embrace an outer periphery of the doorknob.
Abstract: An unlock mechanism for a foldable rear seat back which prevents damage to an unlocked state indicator and a front seat. A warning bezel (24) is slidingly fit in a fixed bezel (22) which is fixed to an upper surface (10A) of a rear seat back (10). A first link (32) engages with the warning bezel (24). The first link (32) is connected to a bell crank (38). The bell crank (38) is urged upward by a spring (46). A pin (54), which is provided upright at a latch (16), is movably inserted into a slot (52) which is formed in an open link (50) which is engaged with the bell crank (38). Accordingly, in an unlocked state, when the warning bezel (24) is pressed into the fixed bezel (22), the first link (32) moves downward against urging force of a spring (46), and the warning bezel (24) is accommodated in the fixed bezel (22).

Abstract: A protective doorknob encasement device which provides a protective cover over the space formed between a door jamb and an exterior doorknob to prevent insertion of a tool to forcibly open the door. The invention includes a mounting plate and a track guide to enable slidable attachment of a protective casement. The track guide is configured so as to orient and restrict movement of the casement along the track and only in a direction toward the exterior door surface. Removal of the casement is permitted by its continued forward motion along the track and is only possible when the door is open. This unidirectional forward motion results from use of spring-biased pawls coupled to the casement which catch in corresponding grooves set in the mounting plate to prevent rearward motion. An opening is provided in the casement in alignment with a key slot of the enclosed doorknob to permit normal access.
