A vault door system for use in a vault includes a door supporting a plurality of locking bolts that move between locked and unlocked positions. A drive system includes a prime mover and a drive train. The prime mover actuates the drive train to move the locking bolts between the locked and unlocked positions. An inner handle is at an inner side of the door and is arranged to be accessible from an interior of the vault. The inner handle is operatively coupled to the drive train and is movable between a first position and a second position. In the first position, the drive train operatively couples the prime mover to the plurality of locking bolts so that the prime mover can move the locking bolts between the locked and unlocked positions. In the second position, the drive train does not operatively couple the prime mover to the plurality of locking bolts.

The present disclosure includes a handle assembly system for use with lift and slide doors. The handle assembly can include a handle housing that can serve as a support frame for housing and securing the handle flush within a front face of the door. The handle can be pivoted out of the handle housing and extended to increase length, wherein rotating the handle allows a user to actuate the door panels in order to open and close the sliding door system. The telescoping handle can allow a user to grip the handle and provide a lever-type function to reduce the force required by the user to actuate the panel, such as to lift the panel onto or off the track.

In an outer handle device for a vehicle door, a handle lever is operatively linked to an outer handle, the handle lever being driven by an electric actuator so that the outer handle is pivoted from a housed position to a pop-up position. A restriction device operates so as to follow movement of the handle lever toward a side that goes away from an initial position when the handle lever is driven by the electric actuator so that the outer handle is pivoted from the housed position toward the pop-up position side, the restriction device restricting return of the handle lever to the initial position side from a maximum operated position of the handle lever toward the side that goes away from the initial position. Accordingly, it is possible to prevent the outer handle from rattling, thereby enabling marketability to be enhanced.

A retractable handle arrangement includes a handle movable between stowed and deployed states, a motor and transmission mechanism arranged to couple the motor to the handle for moving the handle from the stowed state to the deployed state when the motor is driven in a first direction, and to modulate the force exerted on the handle and the speed at which the handle is deployed as the handle travels from the stowed state to the deployed state.

An electronic lock, including: a power storage device; and photovoltaic cells located on a surface of the electronic lock, the photovoltaic cells being electrically coupled to the power storage device in order to provide a charging current to the power storage device.

The present invention relates to a door handle and, more specifically, to a door handle which may comprise: a housing which is fixed to a door and has an inner space; a drive part which supplies rotational power; a rotating guide which is connected to the drive part to receive rotational power therefrom and rotate within the housing; and a handle part which is disposed within the rotating guide, and protrudes out of the housing by forward rotation of the rotating guide and is retracted into the housing by reverse rotation of the rotating guide.

A handle assembly for an access panel is described and includes a support structure attached to the access panel; a handle engaging with the support structure, the handle comprising a grip portion and upper and lower flanges extending perpendicularly from the grip portion; and a retention/extension mechanism for retaining the handle in a first position and for transitioning the handle to a second position after pressure is applied to and subsequently released from the handle.

An escape hatch for an aircraft includes a door body having an exterior side and an interior side opposite the exterior side; an exterior handle movably connected to the door body, the exterior handle rotatable between a stowed position, in which the exterior handle is recessed within an opening of the door body, and an unstowed position, the exterior handle being accessible from the exterior side of the door body to open the door; and a visual indicator connected to the door body and visible from the interior side of the door body only when the exterior handle is in the stowed position.

A panel lock includes a shell, a rotating shaft, a locking tab, a handle, a latch hook and a first elastic spring. The rotating shaft is rotatably mounted in the shell. The locking tab is connected to and rotates along with the rotary shaft to realize unlocking and locking. The handle is rotatably mounted to the rotating shaft, and has a first position being folded and a second position being lifted during rotation about a first axis perpendicular to the rotating shaft. The handle includes a latching groove and a guiding portion arranged at a side of the latching groove. The latch hook is rotatably mounted in the shell. The first elastic spring is arranged between the latch hook and the shell. Automatic locking of the handle can be realized during the movement of the handle from the second position to the first position.

A lever-operated latch device includes an assembly of a case body, an actuation body mounted on the case body, a linking member and a slide body. The actuation body has a free end and a pivoted end pivotally connected with the case body in cooperation with elastic members. The free end of the actuation body is formed with two protruding arms and an opening section positioned between the protruding arms. An operation section is disposed in the opening section. The linking member has a first end pivotally connected with the free end of the actuation body (or the operation section) and a second end connected with the slide body. When an operator presses the operation section, the actuation body is permitted to move from a closed position to an opened position so as to drive the linking member and the slide body to move.
