Definitions

• the present invention relates to a door closing device, comprising a curtain composed of a juxtaposition of blades hinged together by a frame and intended to pass, by vertical sliding through at least two slides, a closed position at an open position of said door, or conversely, under the action of motorization means, each slideway comprising means capable of automatically reinserting, during the passage in the closed position of said curtain, a blade and / or an armature outlets of the slide.
• the present invention is in the field of door closing devices of premises and industrial buildings, shops, hangars or the like.
• doors serve as passage for vehicles, such as forklift trucks or the like, and are equipped with a shutter passing from a closed position to an open position, and vice versa, under the action of a motor for winding or folding said flap in a housing at the top of the door, at the lintel.
• This component may be rigid but is preferably semi-rigid or flexible.
• such a flap consists of a juxtaposition of blades hinged together and guided vertically at each of their ends by slides disposed on either side of said door.
• this flap consists of blades interconnected by a strip, in particular plastic or the like, so as to form a curtain.
• a known closure device comprises such a curtain of which each blade is provided to be flexible or articulated so as to come out of the slide when it is subjected to a stress which is laterally subjected to its usual displacement, for example during an impact.
• this type of device is not entirely satisfactory because of the rigidity of the slides, generally metal, which increase the stress required for the extraction of a blade, and therefore the risk of damaging said curtain.
• blade articulation causes maintenance problems over time.
• Another closure device comprises such a curtain sliding in slides whose lateral edges, serving as a guide to said curtain, consist of flexible strips that can deform to allow a blade to come out more easily following an impact.
• Such closure devices also include means for allowing the blades out of their slide following an impact, to reinsert into the latter easily.
• a known device provides a space between the top of the slides and the winding housing of the curtain. In this way, if a blade has come out of the slide, when the rise of the curtain, the blades of the latter slide on the outside of the slides to resume their place in alignment with them. It is then sufficient to lower the curtain to introduce the blades in said slides.
• This device provides to obliquely widen the upper edges of the slides, towards the outside thereof, to improve the insertion of the curtain.
• a disadvantage posed by this type of device resides in protruding parts of said rails which are not necessarily adaptable to any type of door.
• the latter may, during its descent, slide entirely off the rails, for example under a pendulum effect or because of the wind. It is then necessary to leave a portion of the curtain, covering said space, engaged in the end of the slide, so that the upper part of the door remains obstructed.
• Another device provides a guide formed in each of the lateral edges of each slide.
• This guide is in the form of two substantially parallel walls, arranged in inverted V so as to guide the end of each blade towards the inside of the slide during the ascent of the curtain under the traction force of the engine.
• this guide is provided protruding from said edges of the rails so as to force the blades to be inserted into the guide.
• the present invention relates to a door closing device, particularly of industrial type, overcoming the drawbacks of the state of the art and providing another technical solution to the problem posed by the slide exit of a curtain blade in the event of impact .
• closure device according to the invention is simple and inexpensive to implement.
• the invention relates to a door closure device comprising a curtain composed of a juxtaposition of blades hinged together by a frame and intended to pass, by vertical sliding through at least two slides, a closing position at an open position of said door, or conversely, under the action of motorization means, each slide comprising means able to reinsert automatically, when passing in the closed position of said curtain, a blade and / or an armature exits the slide.
• Such a device is characterized in that said reinsertion means comprise symmetrically, on either side of the edges of each of the slides, a guide space opening towards a rail arranged obliquely so that one end of said rail is secured to said slide while the opposite end opens into this slide.
• the reinsertion means are entirely contained in the interior of each of said slides.
• two opposite rails are V-shaped.
• the opposite ends of two rails are spaced substantially from the thickness of a blade of said curtain.
• it comprises several reinsertion means arranged along each slide.
• the reinsertion means are arranged at the same height on each of the slides.
• the reinsertion means are arranged at different heights on each of the slides.
• FIG. 1 shows a perspective view of the door closing device according to the invention.
• FIG. 2 is a partial sectional view of the device according to the invention.
• the present invention is in the field of devices 1 closing door 2, including industrial premises or building door, such as sheds, stores or the like.
• Such a closure device 1 comprises a curtain 3 intended to pass from a closed position to an open position of said door 2, under the action of motorization means, not shown, but which can generally be located at the lintel 4 of said door 2.
• This lintel 4 comprises a space, such as a box, enclosing the means for winding or folding said curtain 3 in the open position.
• said curtain 3 is guided in its movement by guide means comprising two slides 5 solidaires uprights 6 of the door 2.
• These slides 5 may be in the form of a parallelepiped, one of the longitudinal faces is open to let the edge of said curtain 3. The latter then slides vertically along the rails 5, between the edges 7 of each of them.
• the curtain 3 is composed of a juxtaposition of blades 8 hinged together by an armature 9.
• These blades 8 may preferentially be in the form of bars.
• the frame 9 it can be in the form of a canvas, tarpaulin, fabric, strip or film connecting two bars to one another.
• this frame 9 is made of flexible or semi-rigid material, such as a plastic strip. The blades 8 then serve to reinforce said reinforcement 9.
• the curtain 3 is designed to allow the blades 8 and the frame 9 to come out of the slideways 5 in the event of impact, in particular during a shock sustained laterally compared to the usual vertical displacement of said curtain 3.
• said blades 8 may be flexible and / or articulated and / or hinged together.
• the closure device 1 then provides means 10 capable of automatically reinserting a blade 8 and / or the reinforcement 9 in a slideway 5, said blade 8 and / or said reinforcement 9 being previously out of said slide 5 .
• the replacement is effected during the passage in the closed position of said curtain 3, when the latter descends under the action of said motorization means and under its own weight.
• reinsertion means 10 are included on each slide 5, preferably symmetrically on the same slide 5, and are located on either side of the edges 7 of the latter. They may be in the form of a guide space 11 opening towards a rail 12. This rail is preferably arranged obliquely so that one end 13 of said rail is integral with said slide 5 while the opposite end 14 opens to In this way, the reinsertion means 10 are entirely contained in the interior of each slideway 5.
• Two rails 12 are therefore arranged in opposition, symmetrically with respect to the longitudinal axis of a slideway 5, two opposite rails 12 being then V-shaped.
• the symmetrical arrangement of the rails 12 allows the readjustment of the curtain 3 out of a slide 5, regardless of which side of the slide 5 it came out.
• the opposite ends 14 of two rails 12 are spaced substantially from the thickness of a blade 8 of said curtain 3.
• the blades 8 can be perfectly centered along the slide 5, including when the opening or closing the curtain 3, without a blade 8 and / or an armature 9 is out.
• the rails 12 can be made easily by folding of the portion of the slide 5 which will form the guide space 11.

• these reinsertion means 10 are arranged on the height of the slide as shown in FIG.
• these reinsertion means can be arranged at different heights on each of the slides 5. In this way, during the reinsertion of a blade 8 and / or a frame 9, the stress they undergo does not affect by the insertion of the other end of the blade 8 and / or the armature 9.
• the same slide 5 may comprise several reinsertion means 10 arranged along the latter, at different heights.
