Abstract

The invention refers to a quick-opening door comprising: a flexible canvas secured to a motor-driven drum and provided with vertically aligned arrangements of abutment elements that are guided in vertical uprights of the door; an electric duct secured to one of the sides of the canvas and provided with cables connected to a wireless signal transmitter; a plurality of guiding abutment elements distributed along the sides of the canvas with different spaces there between, disposed either singly or in groups; sensors which are disposed in an abutment passage zone and which capture different sequences of pulses during the passage of the abutment elements, thereby determining the position of the canvas at all times; and a contact-detecting band connected to the transmitter via the electric duct and housed in a bag by means of which the canvas is fitted against the ground.

Claims

1. A Quick-opening door, of the type comprising a flexible canvas, secured by its upper end to a motor-driven drum for its winding in an opening position and its unwinding in a closing position of the door;

having said canvas in its lateral ends vertical alignments of abutment elements which are guided in vertical uprights of the door during the vertical displacement of the canvas, being released said abutment element from the vertical uprights when the canvas receives a push action of a certain intensity;

characterized in that it comprises at least;

a hose carrying electrical cables, covered by a tape or sheath welded to the same and secured to one or both side ends of the canvas, containing one of various electrical cables connected to a wireless signal transmitter;

a plurality of guiding abutment elements secured on the lateral ends of the tape or sheath and distributed along said side ends with different separations, in an individual form or by means of groups and assemble with capacity to displace vertically in respect to the vertical uprights of the door;

some sensors arranged in a passage area of the abutment elements which capture different sequences of impulses, during the passage of the abutment elements distributed with different separations on the side ends of the canvas, determining the position of the canvas in any given moment; and

a contact detecting band connected to the transmitter by means of the cables contained within the hose and located within a bag for the adjustment of the canvas on the floor.

2. The door, according to claim 1, characterized in that the hose containing electrical cables is secured to the canvas by means of a support sheath welded to the corresponding side end of the canvas.

3. The door, according to claim 1, characterized in that the radio signals transmitter is secured to the shaft of the motor driven drum.

4. The door, according to claim 1, characterized in that the bag for the adjustment to the floor is secured to the lower end of the canvas, comprising in its interior a sheath containing a weight.

5. The door, according to claim 1, characterized in that each of the vertical uprights of the door comprises:

a vertical profile with a channel having a frontal opening or mouth and an also vertical guide member, having an interior passage for the vertical displacement of the abutment elements, a front opening for the passage and vertical circulation of the side ends of the canvas having the abutment elements and a back arm ending in a vertical appendage which has at least portion located within the lengthwise channel of the profile with capacity for sideways rotation.

6. The door, according to claim 5, characterized in that the internal passage and the front opening of the guide member define a cross section in the form of a “

U”

elastically deformable in sufficient measure to permit the release of the abutment elements when the canvas is submitted to a frontal or oblique push of a particular intensity.

7. The door, according to claim 1, characterized in that the abutment elements secured to the lateral ends of the tape or sheath form protection means for the said tape or sheath against eventual blows and against deterioration by use.

8. The door, according to claim 1, characterized in that the tape or sheath forms self-centering means for the abutment elements.

9. The door, according to claim 1, characterized in that the lateral ends of the canvas have corresponding independent hoses containing electric cables.

10. The door, according to claim 1, characterized in that the guide member comprises in its upper part, some supports in which an optical sensor is located to detect the vertical displacement of the canvas.

11. The door, according to claim 8, characterized in that said supports comprise antifriction parts channeling the canvas towards the interior of the guide member when said canvas has been released from said guide member.

12. The door, according to claim 1 characterized in that the cables located inside of the hose are connected to a mechanical transmitter to transmit signals in a non wireless form.
