Abstract: This invention, which provides a solution to the long-standing problem of motion-related rattle in torsion balances for windows, is based upon the discovery that the major source of the rattle is related to the movement of the free end of the twisted rod that is mounted within the coil of the torsion spring. A sound-deadening element of resin material is secured to the free end of the twisted rod, being positioned proximate to the extremity of the free end, and the preferred element has a maximum dimension (measured radial to the spring) that is greater than the maximum cross-sectional dimension of the twisted rod but less than the effective internal diameter of the coiled spring. The sound-deadening element eliminates the rattle by preventing contact between the free end of the rod and the spring, and it also acts as a glide to facilitate relative movement between the rod and the spring during operation of the balance.

The back portions of the L-shaped fingers are spaced from each other about their integral hinges and are flexible so as to bend toward each other when the shaft is inserted in the socket.

Abstract: A hinge device comprising a shaft, a coil spring, a shaft holder, and a bracket. The coil spring has a coiled portion wound around the main portion of the shaft. The shaft holder is secured to a first member and holds one end of the shaft, thus preventing the shaft from rotating. The bracket supports both end portions of the shaft, and is secured to a second member. The bracket, therefore, allows the first and second members to rotate relative to each other around the shaft. The main portion of the shaft has a cross section having a short diameter and a long diameter. The coiled portion is formed of a plurality of turns contacting one another. Each turn extends at a predetermined pitch angle to a line which extends at right angles to the axis of the shaft. The turn therefore looks elliptical when viewed in the axial direction, and has a short diameter greater than that of the main portion of said shaft, and a long diameter substantially equal to that of the main portion of said shaft.

Abstract: A spring loaded door hinge comprising a rod that moves with the door as the door pivots. Attached to the door frame is a flange. The door is attached to the rod by means of collars. The tails of the coil springs extend from the rod so that they may, depending upon their position, be in position to strike the door frame flange thereby preventing a large shock from being transferred to the door if it is swung open violently. Also the spring hinge allows the door to be easily opened initially with resistance to the door opening being controlled by the positioning of the tails of the coil springs. The springs are distributed vertically to prevent twisting of the door and frame. The tails of the spring coils are hooked so that the can engage the door frame flange if extreme force is placed upon the door when opening. The hooks set a limit as to how far the door may be opened and prevent the spring tail from binding between the flange and the spring coil.
