Abstract: A door closing hinge device includes two flaps for attaching to a door frame and a door panel, a seat and a housing attached to the flaps. A follower is slidably disposed in the housing, and includes an inclined surface for engaging with an inclined surface of the seat, and for moving the follower up and down relative to the housing when the follower and the housing are rotated relative to the seat. A guiding device may guide the follower to move up and down relative to the housing, and a forcing device may force the follower and the door panel to rotate relative to the door frame back to an original position where the inclined surfaces of the seat and the follower are engaged with each other.

Abstract: A wheel chair includes a back support pivotally attached to a base frame and having a handle and a hand grip pivotally attached to the handle, a housing is secured to the base frame and includes a chamber to slidably receive a shank which has one end pivotally attached to the back support. An adjustably anchoring device may be used to adjustably anchor the shank to the housing, and to adjustably secure the back support to the base frame to selected angular position. One or more coil springs are engaged onto the shank, and have an inner diameter smaller than an outer diameter of the shank, to allow the springs to be engaged and clamped onto the shank, and to be expanded and released from the shank by a barrel.
