Abstract:
Insulated doors with restorable breakaway sections are disclosed. An example door includes a first panel assembly including a leading panel and a trailing panel. The leading panel is to be in substantially coplanar alignment with the trailing panel when the first panel assembly is in a normal configuration. The leading panel is to be angularly displaced out of coplanar alignment with the trailing panel when the first panel assembly is in a dislodged configuration. The example door further includes a tension member to connect the leading panel to the trailing panel. The tension member is to resiliently urge the leading panel and the trailing panel toward each other in a horizontal direction. The tension member is to resiliently urge the first panel assembly toward the normal configuration when the first panel assembly is in the dislodged configuration.
Abstract:
A sliding door for selectively opening and closing and opening is disclosed. The door is comprised of a door panel having a top, a bottom, a leading edge and a trailing edge. The door panel translates laterally relative to the opening between a closed position and an open position. The door also includes a guide located proximate the opening and between an upper and lower extent of the opening. The door also has an elongate beam attached to the door panel between the top and the bottom. A first portion of the elongate beam extends generally horizontally along a vertical plane of the door panel, and a second portion of the elongate beam extends away from the leading edge of the door panel, beyond the trailing edge of the door panel and operably engages the guide.

Abstract:
An automatic sliding door system especially well suited for use in walk-in freezer or refrigerator units includes an exterior sensor unit for detecting opening conditions on the exterior of a freezer or refrigerator unit, and an interior sensor unit for detecting opening conditions in the interior of the freezer or refrigerator unit. Each sensor unit comprises both a motion sensor and a presence detector. The motion sensor detects motion towards the sliding doors, and opens the doors as they are approached. Once motion is detected, the motion sensor tracks the motion no matter whether towards or away from the door, and keep the doors open so long as the motion is present. The presence detector of each sensor unit detects a change in the ambient conditions directly underneath the doorway, and keeps the door open when the ambient conditions change.
Abstract:
An arrangement for a close-fitting sliding door, particularly to a cold or freeze store, comprises a door panel (1) onto which various components are mounted and a travel rail (8) as well as elements (22, 23) for guiding the door. In order to produce a door of this type which may be used as a leftwards as well as a rightwards closing door and which is at the same time readily assembled, the travel rail (8) is constituted by a profile (10) forming a track (9) in which the support rollers (7) of the door are provided when the door is in a closed position, at least one additional profile (11) which jointly with the first profile (10) form a sliding rail (14) for the support rollers (7) when the door is in an open position, and a taper piece (15) connecting the two rails (9, 14). The elements for guiding the opposite side of the door is constituted by a profile (22) having a face sloping downwards and inwards towards the frame structure (4), and guide members (23) provided with a similarly sloping face (26) co-acting with the face of the guide rail. Said travel rail and such guide elements impart to the door a slopingly downwards and inwards translatory motion towards the frame (4) when the door is closed by the support rollers (7) being placed in the track (9).
Abstract:
A seal for a door includes a first mounting rail (308) and a second mounting rail (310) spaced apart from the first mounting rail (308). The seal further includes a flexible sheet (144) extending between the first mounting rail (308) and the second mounting rail (310). The flexible sheet (144) is to be biased away from the first and second mounting rails to sealingly engage the door (102) when the door is in a closed position.
Abstract:
A hinge for cold rooms, swing gates or the like, which comprise a stationary support structure (S) and at least a door (A) movable between an open door position and a closed door position. The hinge comprises a box-like hinge body (3) and a pin (5) reciprocally rotatably coupled to rotate about a first axis (X) between the open door position and the closed door position. Closing means are provided (10) for automatically returning the door (A), as well as a working fluid acting thereon to hydraulically contrast their action. The closing means (10) comprise a cam element (11 ) unitary with said pin (5) interacting with a plunger element (12) housed in an operating chamber (25) defined within the box-like hinge body (3). The box-like hinge body (3) has an elongated shape to define a second axis (Y) perpendicular to the first one (X).

Abstract:
A sliding door for selectively opening and closing an opening is disclosed. The door comprises a first guide track defining a first linear guide path and a second guide track defining a second linear guide path. The second guide track is spaced from the first guide track. the door further comprises a door panel having a top edge, a bottom edge, a leading edge and a trailing edge. The door panel is adapted to translate laterally relative to the opening between a closed position and an open position. A first portion of the door panel is attached to the first guide track and a second portion of the door panel is attached to the second guide track.
Abstract:
An access system for a temperature-controlled storage device includes a perimeter frame and least one display case door mounted within the perimeter frame. The perimeter frame and the at least one display case door are configured to move substantially vertically along a surface of the temperature-controlled storage device between a raised position and a lowered position. The at least one display case door is further configured to move substantially horizontally between an open position and a closed position when the perimeter frame is in the lowered position. The access system further includes a torsion spring and motor assembly coupled to the perimeter frame and configured to move the perimeter frame and the at least one display case door between the raised position and the lowered position.
