Abstract: The door handle assembly includes a housing and a lever handle pivotally connected to the front side of the housing by a pin. A pivot plate is pivotally connected to the back side of the housing, which includes a curved channel in which is mounted a compression spring. The pivot plate covers the channel so as to retain or close the spring in the channel. The pivot plate includes an arm which is linked to the door latch. Upon actuation of the handle, the pivot plate is pivoted by a leg of the handle extending through the housing. The pivotal movement of the pivot plate compresses the spring between one end of the channel and an arm on the pivot plate. The linkage between the pivot plate and the door latch releases the latch when the pivot plate is rotated by actuation of the handle. Upon release of the handle, the compression spring biases the pivot plate to its normal at-rest position. A resilient, integrally formed pin retention member extends from the housing for retaining the door handle pin in position.

The keypad includes indicia that inform the user of the extended or retracted condition of the bolt. A battery pack is used to energize circuitry, and the circuitry provides a control signal that activates a solenoid to extend or retract a bolt blocking device, which in turn prevents or enables movement of the bolt. A visual indicator warns of a low voltage or power condition in the battery pack. Electrical contacts are provided in the face plate of the handle to connect the circuitry to an external power source in case the battery pack fails.

Abstract: A lock assembly with a lock spindle extending perpendicular from the internal lock mechanism and the door. A knob or lever is operably connected to the spindle such that rotation thereof operates the lock mechanism. In order to eliminate any movement between the spindle and knob or lever and thereby eliminate rattle or inoperative rotation of the knob, a bow spring is longitudinally mounted to the spindle. The ends of the spring are retained on the spindle as the spring bows radially outwardly from the spindle to frictionally engage an inner wall of the knob or lever.

Abstract: A user of a self-powered electronic combination lock rotates an outer dial to cause generators to generate energy for storage in a capacitor bank. The user then rotates an inner dial to cause a microcontroller to sequentially display a combination of numbers, and presses the inner dial to select a displayed number. The microcontroller determines direction and extent of motion of the inner dial by receiving signals derived from Wiegand sensors placed in proximity to a magnetized disc which rotates integrally with the inner dial, and controls the display of numerals on an LCD display accordingly. When the microcontroller determines that a correct combination has been entered, it activates a motor to move a motor cam to act directly on a locking lever so that the locking lever can engage a drive cam integrally linked with the inner dial, to allow the inner dial to withdraw the lock's bolt.

Abstract: A fastening mechanism for a handle on a cooking utensil should also have a releasable design for certain uses, for example, when the cooking utensil is heated up in a closed oven. A release and subsequent reconnection of a handle thereby should be done quickly and without effort, and the fastening mechanism for the handle moreover should be easy to manufacture. The fastening mechanism uses for this purpose an operating piece, which can be adjusted transversely with respect to the longitudinal extent of a handle piece in such a fastening mechanism. During the handling of which operating piece, a locking of the handle piece on a holding piece is released, which handle piece is covered by the handle piece and is connected to the cooking utensil. A renewed slipping over of the handle piece occurs against a light resiliency resulting from a transfer slope on a spring piece which also is used for the locking.

The inner and outer members are detachably engaged with one another, and the inner member is detachably engaged with the handle lever by a latch pawl that engages with a latch opening in the handle lever. The upper latch pawl is exposed to the outside of the grip member through a window opening formed in the outer member and the latch opening. The engagement between the inner member and the handle lever can be released through the window opening.

Abstract: This lockset has a threaded inside sleeve extending out from its central housing, the sleeve enclosing the inside spindle for the lockset. An inside rose and handle assembly is provided, the rose having inward tabs. A nut is threaded onto the sleeve and has spaced openings about its end remote from the housing, the openings each leading to a series of steps in clockwise direction progressively closer to the housing.
