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 modular merchandise display system is provided. The system comprises an enclosure, a first upper bracket and a first lower bracket forming a first pocket on a first side of the enclosure, and a second upper bracket and a second lower bracket forming a second pocket on a second side of the enclosure. A first security door is slidably and pivotally connected to the first upper and lower brackets. A second security door slidably and pivotally connected to the second upper and lower brackets. The security doors can be positioned exterior of the enclosure and then pivoted about the upper and lower brackets to be positioned substantially parallel to the front of the enclosure in a closed position. The security doors can then be secured to one another in the closed position.

A retail display unit includes a top, a base including a slot and at least one swing door. The at least one swing door is rotatably coupled to the top and the base and includes a main panel and a lower rail engaged with a bottom of the main panel. A door catch is mounted to a back side of the lower rail and has a channel opening that faces downwardly at the base. A latch is rotatable through the slot in the base. When the at least one swing door is in a closed position, the latch is rotated through the slot in the base and positioned in the channel opening of the door catch to lock the at least one swing door.

In one general aspect, the subject matter described in this specification can be embodied in a display case door that includes an insulated panel assembly that is transparent to visible light. The door further includes a door frame extending about and secured to a peripheral edge of the insulated panel assembly, an electronic display overlaying the insulated panel assembly, and at least one lift-off hinge including a first hinge component attached to a longitudinal side of the door frame, and a second hinge component coupled to the electronic display.

A support device for slidingly supporting, and linearly moving along a longitudinal axis, an object such as e.g. a leaf.

On the object a magnetic return force develops generated by the cooperation of a magnetic flux generator (54, 56) and an element reactive to the magnetic field. The element can slide parallel to the axis during the displacement of the object and correspondingly exhibits a section which, seen in a plane orthogonal to the axis, has a width that varies along the length of the first element parallel to said axis.

A display case including a frame with a first fastener, a door with a second fastener, and a bracket coupling the door to the frame is described. The bracket has a first end coupled a second end. The first end is pivotably coupled to the frame by the first fastener. The first end includes a first pair of spring arms having a first slot to couple to the first fastener and to allow the door to pivot between open and closed positions. The second end is slideably coupled to the door by the second fastener. The second end has detents on a second pair of spring arms and a second slot to allow the second fastener of the door to slide as the door is pivoted between open and closed positions. A first detent is positioned further from the first end of the bracket than a second detent.

A museum showcase includes a guide system for a sliding door, including upper and lower guide mechanisms. The upper guide mechanism includes primary and secondary rails. The upper guide mechanism also includes a first slide unit and a second slide unit. The first slide unit has a rolling member on an upper horizontal track of the secondary rail, and a sliding block engaged on a vertical track of the secondary rail. The second slide unit has a rolling member on a lower horizontal track of the primary rail, and a sliding block engaged on a vertical track of the primary rail. Thereby, the upper guide mechanism is extremely strong. The weight of the door, entirely supported by the secondary rail, is discharged on the first rail by the two slide units to transmit both vertical and horizontal loads.

An electronic locking device to secure linear transitioning or sliding doors. The electronic lock may include a bolt driven by a motor between a locked or extended position and an unlocked or retracted position. The bolt may be coupled to a sled, the sled moved by the motor between a forward position, placing the bolt in the locked position, and a rearward position, placing the bolt in the unlocked position. The motor may drive a drive screw to move the sled.

An exercise storage system includes a storage compartment including at least one storage element. Exercise equipment is stored on the storage elements. A door is connected to the storage compartment with a hinge such that the viewing angle of the door is adjustable. A display on the door includes a backlit display and a mirrored display. A user may select exercise equipment from the storage compartment and perform an exercise activity while viewing the display.

The present invention includes various types of open-air display cases for displaying, storing, and/or vending food, beverages, or other products having a movable barrier that can be automatically positioned over an open front or side of such a unit to prevent access to the products therein when temperatures, component failure, lost power supply, or other variables affect the condition of the items stored in the display case, and methods of using such units.
