A display case door assembly for a temperature-controlled storage device includes a frame defining an opening into the temperature-controlled storage device and a transparent unit coupled to the frame. The transparent unit includes a first vacuum pane, a second vacuum pane, and an evacuated gap between the first and second vacuum panes. The evacuated gap has a predetermined thickness within which a vacuum is drawn, thereby providing a thermal insulation effect for the transparent unit. The transparent unit further includes a plurality of spacers disposed within the evacuated gap and configured to maintain the predetermined thickness of the evacuated gap when the vacuum is drawn therein.

A travel assistance device includes a first rail inclined downward from a first end portion side to a second end portion side in longitudinal direction, a second rail provided parallel to the first rail and inclined, in opposite direction to the first rail, downward from the second end portion to the first end portion in the longitudinal direction, a holding member having a runner portion slidably guided by the rails and holding a travelling body, and a switch mechanism configured to be switched between a state in which the runner portion is guided by the first rail and is assisted to travel downward on the first rail by a load applied to the runner portion and a state in which the runner portion is guided by the second rail and is assisted to travel downward on the second rail by the load applied to the runner portion.

A garage door carrier system carries an overhead garage door between a closed position blocking entry of a vehicle into a garage, and an open position allowing entry of the vehicle into the garage. The garage door is in rolling engagement with a track that guides the garage door. A lever, rotating about a pivot, has a counterweight at a first end and is rotatably connected to the garage door at a second opposite load end. The counterweight provides in-force at the first end that translates as out-force at the load end as the lever rotates about the pivot to carry the garage door between the closed position and the open position.

The invention relates to a sliding door arrangement for a freezer cabinet, comprising a door frame, at least one sliding door, wherein the sliding door is movable along the frame plane between an open position and a closed position, and a guiding device. The guiding device comprises roller arrangements each with a first roller axis and at least one guiding element guiding the movement of the sliding door. The sliding door arrangement is characterized in that the guiding device is designed in such a manner that the sliding door moves transversely to the frame plane during a movement from the open position to the closed position, for which purpose, the guiding element has a parallel portion and an end portion, and the roller arrangements each have at least one further roller axis.

A latch is provided for latching and automatically unlatching a lid from a waste container. The latch mechanism includes a release weight that moves responsive to gravity in a housing from a first position to a second position to cause the latch to disengage from a striker when the latch is rotated to a dump angular orientation. The latch includes a damper that controls movement of the release weight in the housing such that an amount of time for the release weight to move responsive to gravity from the first position to the second position is at least two times an amount of time the release weight would take to move responsive to gravity from the first position to the second position absent the effect of the damper.

A doorway system for a robotic vehicle that accesses a separated area through a barrier that has a doorway formed through it. The system includes a wireless transmitter that transmits an electronic signal from the robotic vehicle, and a door movably disposed within the doorway, between a closed position and an open position. A doorway device with a wireless receiver that is coupled to a locking mechanism is configured to selectively engage and lock the door at the closed position, and unlock the door upon receipt of the electronic signal by the wireless receiver. Movement of the robotic vehicle toward the doorway device enables communication of the electronic signal from the wireless transmitter to the wireless receiver. Upon passage of the robotic vehicle through the doorway to the separated area, and return of the door to the closed position, the controller controls the locking mechanism to engage and lock the door.

A lifting apparatus is provided. The lifting apparatus includes a lifting cable supported relative to the ceiling structure, the lifting cable extending along a vertical direction and attaching to a lift point on the flexible divider. The lifting cable is retractable in the vertical direction to lift the flexible divider from a lowered configuration to a raised configuration. The lifting apparatus further includes a guiding element for guiding a position of the lifting cable along a horizontal direction while the flexible divider moves between the lowered configuration and the raised configuration. The guiding element is movably mounted to the ceiling structure to move between a first horizontal position when the flexible divider is in the lowered configuration, and a second horizontal position when the flexible divider is in the raised configuration.
