The invention relates to a quick-operating door designed for opening and closing an aperture in a partition including: a support structure including in particular two vertical jambs (2) above which is a shaft driven by electromechanical means, each of the two vertical jambs (2) having an outer planar bearing surface (6) and a slideway (5), and a flexible curtain (4) designed to occupy a closed position in which the curtain (4) blocks the aperture and an open position in which the curtain (4) clears access to the aperture, the curtain (4) incorporating at least two transverse reinforcing bars (19) provided, at each of the ends thereof, with a tip in the form of a crank which engages with the guiding slideway in each jamb. According to the invention, the door has at least one transverse section (22) of the curtain (4) delimited by two transverse reinforcing bars (19) including two panels (23) connected to one another by means of a hinge (24), each panel (23) consisting of at least two strips (25) of a flexible material between which is inserted a layer of material stiffening, weighting and insulating said panel (23) for the purpose of keeping the transverse section (22) bearing on a planar surface (6) of each jamb (2).

The invention relates to a folding door and a shutter guide device. The inventive door comprises two vertical slides (2) and at least one flexible shutter (4) which can be folded in the upper part of the slides and which comprises at least one transverse stiffening bar (12). According to the invention, a guide device (14) is inserted into the extension of at least one stiffening bar (12), thereby forming a guide for the shutter (4) in at least one of the slides (2) in a plane that is offset in relation to the plane of the shutter (4), said shutter (4) being applied against a surface of the slide (2).

The invention relates to a door comprising a frame and an apron (4) which can be moved by drive means between a closed position and an open position. The apron comprises obstacle-detection means which are connected by a cable (20) to a device for controlling the drive means. A first end (21) of the cable is associated with the. apron, while the second end (22) thereof is associated with the frame. The first and/or second end(s) of the cable comprise(s) a connector (19,23) which is mounted to an area of the apron or the frame such that it can rotate around an axis (26, 34) that is perpendicular to said area and which can be separated into two reconnectable parts by means of pulling. In this way, it is possible to detect one end of the cable associated with the apron or the frame.

This high-speed door is provided for closing a bay made in a wall (4) delimited by a lintel and by two vertical sides. The door comprises: two lateral parts placed in an essentially vertical manner against each of the vertical sides of the bay; a shaft (12) positioned at the level of the lintel of the bay and rotationally driven by electromechanical means, and; a curtain (7) made of a flexible material having a first side (7a) and a second side (7b), joined to the shaft (12), the rotation of the shaft (12) being able to move the curtain (7) between a closed position in which the curtain (7) closes the bay and an open position in which the curtain (7) opens the bay. In addition, the door comprises flexible means for protecting the shaft (12) which extend between the two lateral parts (2) and (3) and which are capable of coming in contact with the lintel, the flexible protecting means also having first transversal sealing means that can come in transversal contact with the first side (7a) of the curtain (7) when it is in a closed position.
摘要:
A door including two lateral posts each having a slideway bounded by two wings, a transverse element connecting upper ends of the lateral posts, a flexible curtain having lateral edges engaging in each of the slideways, and means for winding the curtain into a door-opening position, where each of the slideways is equipped with a sealing profile having a back wall and two lateral walls substantially forming a U-shape, each of the lateral walls bearing against the wing which is adjacent to it.

The invention concerns a fast door comprising: a structure having in particular two posts (3) in each of which is provided a slide rail (16) and a transverse lintel-forming element (4), and a flexible curtain (12) connected to the structure at the lintel-forming element (4) via electromechanical means controlling the lowering and lifting of the curtain (12), the curtain (12) incorporating at least one flexible reinforcing bar (13, 29) inserted in receiving means provided in the curtain (12), the flexible reinforcing bar (13, 29) capable of being engaged at its ends in each of the slide rails (16) and capable of bending to be released at least from one rail (16) without being subjected to permanent deformation which would impair the operation of the door once reinstalled in its rails. The door further includes means for detecting any contact with the curtain associated with at least one flexible reinforcing bar (13, 29), the detecting means capable of having a normal operating condition when the bar (13, 29) is rectilinear and an abnormal operating condition under the effect of a contact with the curtain (12).

A balancing apparatus for a raisable-curtain goods-handling door includes a shaft on which a curtain is wound up or on which curtain-raising straps are wound up. The shaft supports two drums onto which are wound belts from which two counterweights are suspended. The "long" belt from which a "long" counterweight of "long" mass M.sub.6 is suspended has a length that corresponds to the full stroke of the curtain while the "short" belt of the "short" other counterweight of "short" mass M.sub.5 is shorter and is fastened on the corresponding drum in such a manner as to enable it to wind in either direction on the drum.

A vertically-opening door installation which is exposed to cold on one side includes a vertically-opening flexible curtain (6) and two risers to guide the respective side edges of the curtain. Each riser includes a lining (12) made of a material which is a poor conductor of heat and which lines the inside of the channel section bar, and at least one longitudinally-extending cavity (14) providing a cushion of air between the outside surface of the channel section bar and the inside surface of its lining. The inside surface of lining (12) is smooth. At least one of the longitudinally-extending cavities (14) may include electrical heater resistance (15) or similar heating devices. The riser is provided to prevent frost and ice from forming around the side edges of the curtain of a goods-handling door which is exposed to the cold.
