Abstract: A counterbalancing hinge for range oven doors or the like includes the following features: (a) articulated members one of which is a bracket adapted to be secured to a supporting body structure such as a range and the other of which is an arm adapted to be received within an oven door or the like and carrying a counterbalancing spring, (b) means for selectively adjusting the counterbalancing spring, (c) door leveling means, (d) an arm latching and locking device activated when the door is removed from the arm, (e) a strain separable detent carried by the spring supporting arm to restrain the arm selectively in door-partially open position, (f) counterbalancing spring action controlling mechanism, (g) spring for retaining the door so it can be removed only when in partially open position, (h) only a screwdriver is needed for installing or removing the counterbalancing hinge relative to the installation, (i) only a screwdriver is needed to, adjust, remove or replace the counterbalancing spring.

Abstract: A door closer has an air cylinder which, when pressurized, neutralizes the door closing force applied by the closer so that the door will open with relative ease. The air cylinder is pressurized through a valve which is contained within the door and is operated by a handle on the door.

Abstract: An appliance, such as a domestic oven, with a removable oven door hinged to the appliance. The hinge system includes a pair of hinge mechanisms, where each mechanism includes a stationary bracket supporting a pivoted door guide, a spring-loaded hinged lever carried by the door guide, and a separable mating member in the door for cooperation with the door guide. The door guide includes a slip-on self-supporting wire spring that is operable whenever there is a partial removal of the door from the door guide to cause a locking action between the door guide and the support bracket. When the door is reinstalled on the hinge mechanism, the wire spring is unlocked from the support bracket so the door may be closed.

Abstract: An electric dry-shaving apparatus having a trimmer which is extendible through a rectangular opening in the housing of the apparatus, and which can be retracted, with the opening being closed by a hinged flap.

Abstract: A door of a household refrigerator has a cam cooperating with a striker. The cam is biased into forcible contact with the striker and is of a configuration for urging the door toward the closed position in response to contacting of a first cam portion and the striker.

Abstract: This invention relates to means for imparting angular movement to a first member connected to a second member by a hinge in one sense about said hinge pivot axis. The actuator is formed from a flexible substantially inelastic retaining means connected between two anchorage positions on the members and subtending that angle between the two members which is reduced on the first member moving relative to the second member and includes an elongated inflatable conduit of substantially constant surface area which is mounted between the members and the retaining means. The conduit is inflated to press outwards against the retaining means to cause the retaining means to exert a pulling force between the members to impart angular movement to one of said members relative to the other member in this one sense.

Abstract: A door for closing an opening through a pet confining wall in a building, kennel, pen or the like, said door having a peripheral frame for mounting in the wall opening, a door member having its upper edge portion hinged to the frame on a horizontal axis for swinging movement of the door in either direction from a vertical closed position within the frame, and a spring tensioned slide acting between the frame and a cam on the upper edge of the door to yieldably retain the door in closed position.

Abstract: A door construction for an appliance such as a baking and broiling oven for domestic use. The door has a counterbalance spring mechanism at each side of the door that includes a swing link interposed between the tension spring and the hinge lever of the door to obtain a door balancing torque that substantially follows the torque of the door as it moves between a vertical closed position and a horizontal fully open position.
