A protective enclosure for a food protection system includes a first hinge member, a second hinge member rotatably coupled to the first hinge member, and a coupler selectively repositionable relative to the first hinge member between an engaged position and a disengaged position. In the engaged position, the coupler engages the first hinge member to limit rotation of the coupler relative to the first hinge member. In the disengaged position, the coupler is free to rotate relative to the first hinge member. The coupler is rotatably coupled to the second hinge member such that (a) rotation of the coupler relative to the second hinge member in a first rotational direction is limited and (b) the coupler is free to rotate relative to the second hinge member in a second rotational direction opposite the first rotational direction.

A thermally releasable fastening element, in particular for fastening a door actuator, includes a base body, which is designed to be inserted into a recess or a number of aligned recesses, a core inserted into the base body, at least partially made of a shape memory material, wherein the base body has an unstable area, which is stabilized by the core, and wherein the core is designed to withdraw at least partially from the unstable area upon thermal activation of the shape memory material.

A door drive for arrangement on or in connection with a door system, wherein at least one leaf element of the door system is movable, including a motor unit with a housing, in which a stator is stationarily received, and wherein a rotor is arranged so as to be rotationally-movable in the housing and includes an output shaft, wherein the output shaft can be brought into operative connection in a driving manner with the leaf element. The motor unit has the basic shape of a cuboid, which is formed at least by two housing halves connected to each other.

A movable panel system is provided which has a guide provided with at least one rail, at least one glass panel and a carriage device slidingly supporting the at least one glass panel on the at least one rail. The carriage device has a carriage body engaged to the at least one glass panel, and a wheel group having at least two wheels, configured to slidingly engage the at least one rail, and a support frame, the at least two wheels being hinged, rotationally free, to the support frame. The carriage body and the support frame are mutually engaged by a hinge that allows reciprocal rotation.

Disclosed is an air conditioner including a first frame including a through hole, a second frame rotatably coupleable to the first frame, the second frame including a burring portion at least a portion of which is insertable into the through-hole in a first direction, where while the burring portion is inserted into the through-hole of the first frame, the burring portion protrudes in the first direction, and a burring hole formed by the burring portion, and a fastening member insertable into the burring hole in a second direction opposite to the first direction and configured to function as a rotary shaft of the second frame, where while the fastening member is inserted into the burring hole, the fastening member protrudes in the second direction.

In an aspect, a vehicular door hinge is provided and includes a door-hinge component that is configured to mount to a vehicle door and a body-hinge component that is configured to mount to a vehicle body. The door hinge component is pivotally mounted to the body hinge component. A first one of the door- and body-hinge components is made from folded sheet metal and has a fold. Each of the door- and body-hinge components has a stop surface that is engageable with the stop surface on the other of the door- and body-hinge components to limit relative pivoting movement between the door- and body-hinge components. The stop surface on the first of the door- and body-hinge components is at the fold.

A bracket system that allows a drop shield to be added to a prior art main viewing panel of a food guard. For instance, an existing food guard system can be modified to include a drop shield without having to make a permanent modification, or replacement, in order to close off “reach in” access to food stored beneath the food guard system. The system also reduces or eliminates any gap beneath the main viewing panel of the food guard and the upper edge of the drop shield.

An inverted constant force window balance system has a carrier assembly including a housing with a first and a second housing wall, a coil spring with a free end, and a shoe assembly slidably coupled to the housing. The shoe assembly includes a first and a second shoe face. The housing slides between a first and a second position relative to the shoe assembly. When in the first position, the first and second housing walls are substantially non-coplanar with the first shoe face, and when in the second position, the first housing wall is substantially coplanar with the first shoe face and substantially non-coplanar with the second shoe face. The shoe assembly receives a pivot bar from a window sash and extends a brake upon rotation thereof. The balance system also includes a mounting bracket releasably coupled to the housing and coupled to the free end of the coil spring.

A hinge for a piece of furniture including at least one shoulder and at least one door, said hinge having a first hinge body and a second hinge body, where the first hinge body is connectable to the at least one shoulder of the piece of furniture and the second hinge body is connectable to the at least one door of the piece of furniture, wherein the first hinge body and the second hinge body are operatively connected to each other and relatively movable by means of adjustment means, where one of the first hinge body and the second hinge body includes a cross element, and the other of the first hinge body or the second hinge body defines a cross guide, where the cross element is housed in the cross guide, and where the cross element slides in the cross guide by means of the adjustment means.

The invention relates to a hinge for detachable sheet metal cabinet doors or walls, comprising a first hinge part or frame part that can be secured to the door or cabinet frame, and a second hinge part or door hinge part that can be fixed to the door leaf or cabinet wall, which hinge parts are connected to one another in an articulated manner by means of a hinge pin, and having a latch-type tongue that is arranged in the second hinge part such that it can move against a spring force, characterised by a lifting device which encompasses the hinge pin guided through finger-type ends of the first hinge part and which centrally supports the hinge pin together with a hook retained by the door part, such that the lifting device moves the encompassing part of the second hinge part perpendicular to the plane of the door leaf or cabinet wall, via actuation, by means of a key, such as a double bit key.
