Disclosed are a refrigerator and a refrigerator door opening apparatus. The refrigerator includes a cabinet forming a storage space; a door configured to open and close the storage space; a panel installed on a front surface of the door to form an external appearance; a door handle provided in the panel and operable to open the door; and a door opening apparatus coupled to the door handle and configured to assist in opening the door. The door opening apparatus includes a main module installed inside the panel and configured to protrude backward from the panel according to the operation of the door handle; and a sub-module provided at an end portion of the door corresponding to the main module and configured to protrude backward in conjunction with the main module to push the cabinet and open the door.

A gun safe has a container body, a hinged door and a locking assembly. The container body has apertures in a bolt receiving side of the jam and a corresponding number of door bolts extendable from a second edge of the door. The locking assembly has a barrier panel which defines a narrow longitudinal slot. The slot receives a guard member welded to an internal surface of the door adjacent the second edge, and is reinforced by a barrier panel against lateral flexing or distortion. The closure optionally is mounted to a multi-hinge device that permits the closure to reciprocally translate in a plane P corresponding to the opening. The barrier member is optionally widely spaced from the second edge of the jam to accommodate lateral travel of the guard member on closure. A handle mechanism controls lateral movement of the closure and retraction or extension of the locking bolts.

A pump handle system includes a pump handle and a main shaft. The pump handle is operable to radially pivot from a starting position in a first pivot direction and back to the starting position in a second pivot direction opposite the first pivot direction. The main shaft is driven by the pump handle to rotate approximately a first half of a predetermined rotational distance in a first rotational direction a first time the pump handle is pivoted out from the starting position in the first pivot direction, and rotate approximately a second half of the predetermined rotational distance in the first rotational direction a first time the pump handle is pivoted back to the starting position in the second pivot direction. The main shaft rotates in a second rotational direction opposite the first rotational direction a second time the pump handle is pivoted in the two-movement push-pull motion.

The system is compose of a series of operable louvers mounted on a four sided frame and connected on each side to the operating mechanism that allows for easy opening and closing of the louvers. Every part of the system that is exposing to the exterior of the building is separated from the interior part of the system by a low heat conductivity material as a thermal barrier. Each operable louver is composing of a four sided main frame, two panes of glass (inner and outer) and a coupling mechanism on each side that connects to the operating mechanism. The main frame acts as the thermal break as well as a system that absorbs the energy created when an outside object impacts the window from the outside. The system incorporates sealing devices between all moving parts to eliminate water and air infiltration. The operating system allows for easy opening and closing of the window by rotating each louver with the crank mechanism assisted by springs.

An operator for a window comprising a base and a cover, the base being attached to a window sash with an aperture extending through the base, an arm having first and second ends with a first end secured to the base, the first end of the arm having an aperture therein overlying the aperture in the base and an upper securement member extending at least partially through the aperture in the first end of the arm, the upper securement member having a threaded recess therein, a lower securement member screwthreadedly engaged with the upper securement member and extending through the base in an abutting relationship thereto, the cover engaging with the upper securement member to prevent rotation thereof when the lower securement member is screwthreadedly engaged with the upper securement member.

A crank handle assembly for actuating a panel of a fenestration unit relative to a frame includes an arm. The arm is elongate and is configured to be supported at one end by the frame for rotation to actuate the moveable panel relative to the frame. The crank handle assembly also includes a knob that is moveably attached to an opposite end of the arm and that extends therefrom. The knob is supported for movement between an aligned position and a misaligned position relative to the arm. The arm and the knob cooperatively define a crank handle longitudinal axis. The knob, in the aligned position, is aligned with the arm and the crank handle longitudinal axis is straight. The knob, in the misaligned position, is misaligned with the arm, and the crank handle longitudinal axis is nonlinear.

A casement window operator includes a linear input mechanism configured to be mounted to a stationary frame of a casement window, a linear to rotary motion converter operably coupled to an output of the linear input mechanism, a gear reducer operably coupled to an output of the rotary motion converter, and a sash arm operably coupled to an output of the gear reducer to rotate in conjunction with the output of the gear reducer. The sash arm is configured to extend from the stationary frame of the casement window to a rotatable window sash of the casement window.
