Abstract:
This fast door (1) being able to close off an opening made in a partition comprises: - a structure having notably two vertical uprights (3) in each of which a slide (5) is arranged, and a top horizontal element forming a lintel, and - a flexible screen (12) connected to the structure at the element forming a lintel by electromechanical means controlling the lowering and the raising of the screen (12), - control means for controlling the electromechanical means controlling the movement of the screen (12). According to the invention, at its bottom transverse end, the flexible screen (12) is fitted: - with a ballasting element that is rectilinear and flexible in a vertical plane and in a horizontal plane, capable of deforming and then resuming its rectilinear shape after a contact with an object placed on the trajectory of the screen (12) or encountering the latter, and - contact detection means positioned between the flexible ballasting element (14) and the bottom free end of the screen (12) connected to the control means and having a normal operating state and an abnormal operating state, the detection means being associated with the flexible ballasting element (14), and being capable of switching from the normal operating state to the abnormal operating state when there is a contact of the screen with a static or moving object placed on the trajectory of the screen (12) by a deformation of the flexible ballasting element (14) or of the bottom free end of the screen, the change of state of the detection means being converted into a signal that is transmitted to the control means for the purpose of ordering the stoppage and/or the raising of the screen to its open position by resuming its normal trajectory, and doing this with no external intervention on the flexible ballasting element (14) nor on the control means, nor on the screen (12), nor on the slides (5).
Abstract:
Die Erfindung betrifft eine Antriebsvorrichtung (1.1-1.4) aus einer Antriebseinheit (2,8) und einer Abtriebseineinheit (6,9), die beide mittels einer doppelseitig wirkenden Rutschkupplung (1,2) verbindbar sind, wobei die in beiden Drehrichtungen wirkenden Freigabemomente wählbar sind, insbesondere für den Antrieb einer Wickelwelle eines Rollladens, einer Markise, einer Jalousie oder dergleichen, vorzugsweise bei Dachfenstern. Um Falscheinwirkungen auf die Wickelwelle zu vermeiden, die beispielsweise bei schrägen Dachfenstern beim Öffnen und Schließen des Dachfensters entstehen, ist die Rutschkupplung (1,2) für jede Drehrichtung mit mindestens einer als Schleppfeder arbeitenden Schraubenfeder (3-5) ausgebildet, deren Freigabemoment derart bemessen ist, dass ein Falscheinwirkungen verhinderndes Auslösemoment erzeugt wird.
Abstract:
The invention relates to a rolling-up device comprising a tube (1) upon which a canvas (24) is attachable, the rolling-up device being arranged to be attached in two external means of attachment (16, 17), the rolling-up device further comprising a spring- controlled drive mechanism (11, 12, 13) that is tensioned when the canvas (24) of the rolling-up device is unrolled, in order to be able to roll up the canvas (24) again, the rolling-up device further comprising an inner bar (2) inside the tube (1), which inner bar (2) is arranged to be able to connect to at least one of the external means of attachment (16, 17), and the tube (1) furthermore being arranged to be rotatable about the inner bar (2), wherein a braking nut (4) that is laterally translatable inside the tube (1) and that encloses the inner bar (2) and is arranged to rotate together with the tube (1), said braking nut (4) being arranged to translate laterally along the inner bar (2) as the tube (1) rotates, the direction of the lateral translation depending on the rotary direction of the tube (1), whereby a braking action is formed from the work that is required to laterally translate the braking nut (4).
Abstract:
The roller shutter for a building door or window has a panel with louvres (3,4) and an integral sensor (8) for break in attempts, connected to the shutter drive and an alarm (11). The sensor can be connected to the drive and alarm via a radio connection. One of the louvres can be aluminum, with at least one slot (12) positioned as a function of the wavelength to act as an antenna.
Abstract:
Le dispositif de sécurité pour porte de manutention (1) à enroulement ou empilement comportant un tablier ou rideau souple (5) qui se déplace entre une position d'ouverture et une position de fermeture à l'intérieur d'un dispositif de guidage (8) formant une glissière (15), comprend au moins deux paires de cellules de sécurité (23, 24) disposées de part et d'autre de la glissière (15) et à une même hauteur h" par rapport au sol S afin que chaque paire de cellules de sécurité (23, 24) émette respectivement un faisceau horizontal F3 et F4 placé en amont et en aval du tablier ou rideau souple (5), lesdites paires de cellules de sécurité (23, 24) étant montées électriquement en parallèle afin que seule l'interruption ou la coupure des deux faisceaux F3 et F4 en même temps permette d'arrêter la descente du tablier ou rideau souple (5) et d'assurer la remontée de ce dernier en position d'ouverture.
Abstract:
The invention relates to a slatted shutter system comprising an improved self-locking device. More specifically, the invention relates to a self-locking shutter system which does not require intermediate elements in the form of sections. The inventive system consists of: a pair of track guides (2) comprising interlocking openings (21) which are spaced uniformly along the length thereof; at least two contiguous slats (1) comprising complementary through holes (120, 121) which are provided in the lateral area that extends inside the track guides; and at least one locking device (3) which is mounted between the contiguous slats such as to extend through the aforementioned complementary holes in order to be locked in the interlocking openings when the slatted shutter is fully deployed or with the exertion of an upward force (F1), and which retracts from said interlocking openings (21) with the application of a downward lifting force (F2) which is exerted by means of a mechanism for lifting/lowering the shutter material.
Abstract:
A sunscreen assembly is provided comprising a winding tube (1) which is rotatably mounted on a stationary axis (2) and which is springloaded in a first rotational sense and which further comprises a sunscreen (7) which can be wound onto said winding tube (1) when the winding tube rotates in the said first rotational sense and which can be wound off said winding tube when the winding tube is rotated in a second rotational sense against the spring-load. A friction mechanism is positioned between the stationary axis (2) and the winding tube (1), which friction mechanism only generates a friction force on the winding tube when the latter rotates in the first rotational sense.
Abstract:
Even when a damper is provided for absorbing impact and collision noise produced during winding a screen in an automatic winding screen device, the resistance during unwinding the screen is reduced as small as possible, and in the automatic winding screen device having a coil spring fixed to a bracket at one end of a winding box, the other end of the coil spring being fixed to a winding shaft, and the damper for alleviating the impact and collision noise, between the damper on a fixed shaft fixed to the winding box and the winding shaft, a one-way clutch mechanism is interposed in that when the winding shaft is rotated in a direction unwinding the screen against the rotational biassing force of the coil spring, the connection between the damper and the winding shaft is cancelled while when the winding shaft rotates in a direction winding the screen, the damper is connected to the winding shaft.
