Definitions

• the present invention relates to a fast door whose operation is secure.
• doors comprising a flexible screen that can quickly move from a closed position to an open position
• a constant concern is securing the operation of these doors.
• These doors can be made to perform a large number of opening / closing cycles and one can deplore failures that can result in a rapid descent of the screen. This fall of the screen can be done on a person and may hurt it.
• the strap which is connected to the base of the screen is no longer subjected to its normal tension given by the weight of the screen, which then triggers an alarm, - an attempt to intrude by lifting the lower edge of the door.
• the lifting of the door causes a drop in tension of the strap which then triggers an alert, - a rupture of a traction strap.
• the movable member as described in document EP-A-819 204, is generally satisfactory in that it makes it possible to trigger an alarm in the event of an obstacle placed on the descent path of the screen or in case of intrusion. Nevertheless, the reliability of this organ can be improved.
• An object of the invention is therefore to provide a rapid door having a safety device operating by monitoring the tension of a strap which is of a very high reliability.
• the subject of the invention is essentially a fast door, closing a bay formed in a partition comprising, a flexible screen, means for raising the screen comprising, inter alia, a winding shaft fixed at a level lintel of the door, and a strap whose one end is fixed on the winding shaft and whose other end is fixed to the base of the screen, characterized in that the strap travels through a detector of voltage comprising a movable element having an opening in which the strap is engaged, the movable element being held in a first position said normal operating by the strap, the latter being subjected to a normal operating voltage, the movable member tilting in a position called abnormal operation, when the strap has a voltage below a predetermined threshold corresponding to an abnormal operation of the door.
• the idea underlying the invention is to engage a strap in a voltage detector that switches when the tension of the strap is not equal to the normal voltage.
• the voltage detector does not interfere with door operation when operating in a normal mode.
• the screen meets an obstacle during its descent, the tree continues its rotation and the strap passing through the voltage detector relaxes invariably causing a tilting thereof.
• the voltage detector switches to its abnormal operating position, also, in the case of an attempted intrusion by the lower edge of the screen. Raising the lower edge of the screen also causes a drop in tension in the strap passing through the voltage detector.
• the high reliability of the voltage detector of the door is due to the fact that the strap passes directly into a movable element whose tilting makes it possible to signal an abnormal operation of the door.
• the movable element of the voltage detector is biased towards the second so-called abnormal operating position by a return spring.
• moving the movable member from its normal operating position to its abnormal operating position triggers an alert.
• the voltage detector comprises a cylinder movable in rotation about its axis, in which is formed a slot passing through its axis and in which the strap is engaged. This embodiment is extremely advantageous in terms of reliability of operation and space, which allows to equip existing doors with a voltage detector according to the invention.
• the movable cylinder is supported by two flanges.
• An advantageous characteristic of the invention provides that the cylinder is provided with a stud passing through an arcuate groove formed in one of the flanges, this stud coming into contact with a finger connected to warning means, when the cylinder is in the abnormal operating position. By adjusting the position of the finger, it is thus possible to adjust the sensitivity of the device. Depending on the settings, a small angular stroke of the pin (and therefore of the cylinder) or a large angular stroke of the pin may, at the option of a user, trigger an alert. It is noted that the detector has at least one cylindrical roller for guiding the strap towards the mobile cylinder.
• the detector is an autonomous element that can be easily installed on an existing door.
• the door is a folding door
• the strap serving as a means of pulling the screen
• - the door is a roll-up door
• the strap serving as a strap to the good tension of the screen.
• the strap could present a security problem especially if a person came to pass an arm in the latter.
• the strap is attached to the lower edge of the screen by connecting means capable of breaking under a predetermined force.
• the connecting means consist of two elements of self-gripping material of the loop and hook type placed respectively at the end of the strip and on the screen;
• the connecting means consist of two magnetic elements; of different polarity placed respectively at the end of the strip and on the screen, - the connecting means are constituted by a ruptible zone in the band.

• Figure 2 is a perspective view of a voltage detector fitted to this door
• Figure 3 is a cross-sectional view of the detector in a first position.
• Figure 4 is a cross sectional view of this detector in a second position thereof
• Figure 5 to 7 schematically illustrate the operation of rolling or folding doors in normal and abnormal mode.
• FIG. 1 shows a folding door comprising a winding shaft 2 on which strips 3 and 7 are wound.
• this door has a cowling 4 and uprights 5 serving to guide the lateral edges of the door. 'screen.
• Figure 1 shows only the upper part of this door, this door also having quite conventional characteristics.
• this door is distinguished in that it is equipped with a voltage detector 6 of the strap 7.
• This voltage detector 6 is embedded on the door at the level of his lintel.
• the so-called traction strap 7 is fixed, on the one hand, to the winding shaft 2 and, on the other hand, on the screen at the lower edge 8 of this one.
• the pull strap 7 is held taut by the weight of the screen which, in many cases, incorporates transverse stiffening bars.
• the strap 3 doubles the traction strap 7 and has the function of preventing the screen from falling in the event of rupture or distension of the strap 7.
• FIG. 2 shows, in more detail, the voltage detector 6 on board level of the lintel of the door of Figure 1.
• This voltage detector 6 has a cylinder 8 in which is formed a slot 9 diametrical through the cylinder 8.
• the cylinder 8 is supported by two flanges 10, themselves fixed on a plate background 1 1.
• the cylinder is connected to each of the flanges 10 by a pivot connection which allows rotation of the cylinder relative thereto.
• a return spring urges the cylinder 8 into a position in which the slot 9 is oriented in a direction perpendicular to the bottom plate January 1.
• one of the flanges is provided with a groove 13 in the form of an arc in which a stud 14 integral with the cylinder 8 passes. This groove 13 extends over an angular sector of the order of 180 ° and corresponds to the two extreme positions of the cylinder 8.
• the flange 10 supports a sensor 17 which is associated with a finger 16 which is on the stroke of the stud 14. It is also noted that the voltage detector 6 is equipped with two cylindrical rollers 19 placed on either side of the cylinder 8. The operation of the voltage detector is therefore as follows. As can be seen in FIG. 1, the voltage detector 6 is extremely compact. In normal operation of the door, the voltage detector 6 is in a configuration shown in FIG. 3. In this mode of operation, the strap 7 provides an orientation of the slot 9 formed in the cylinder such that the slot is substantially parallel at the bottom plate. This orientation of the cylinder is due exclusively to the action of the strap 7. In this configuration, the strap 7 slides in the voltage detector according to the upward or downward movements of the screen 21.
• FIG. 4 illustrates the configuration of the voltage detector 6.
• the stud 14 comes during its course in the groove 13 in the form of an arc in contact with the finger 16 which acts on the sensor 17. The latter orders an alert action which, in the example shown in Figure 5, is the ignition of a bulb 22.
• alarms can then be triggered: it can be an alarm sound ; it can also be ordered to the motor controlling the rotation of the shaft 2 to immediately stop its action or to reverse its direction of rotation to raise the screen 21 by an unbroken 3 traction strap.
• the detector of voltage 6 acts in the same way. Indeed, due to the lifting of the lower edge of the screen 21 at which one end of the strap 7 is fixed, there is a decrease in the tension thereof. When this drop in voltage reaches a certain value, the return spring acts on the cylinder 8 and tilts it to its position in which it is illustrated in FIG. 4.
• the voltage detector 6 as shown, is a compact module that can equip existing doors, which lack a security system.
• this voltage detector can equip both rolling doors, as shown in FIGS. 6 and 7, that is to say doors in which the screen 21.
• the door is equipped with a control strap 25, which does not participate in raising the screen 21, but only follows the movements of the screen and is thus representative of a normal operation of the screen.
