Description

The present invention relates to a tulip for guiding a

  apron of a roller shutter and a roller shutter mechanism support device comprising such a tulip.

  Such a tulip is also called blade guide and is used to promote the engagement of the apron blades in a lateral guide guide during its course. The tulip is intended to be assembled to a mechanism support plate of the roller shutter, said tulip comprising a guide chute and a foot to be introduced with the support plate in the lateral guide slide of said apron. The tulip is an element of the shutter mechanism support device, which also comprises support plates on which are mounted the various mechanisms of the shutter, such as the operating winch or the engine. Such a device is described in patent FR 2 743 599, and comprises a tulip provided with two lugs at the guide chute and the foot, the two lugs snapping into corresponding holes provided on the support plate. The assembly thus formed is then inserted into a chamber provided in the lateral guide slide. The plates of the rolling shutter mechanism support generally constitute consoles attached to each end of the rolling shutter box. When two openings, such as a window or a door, are arranged close to each other, it may be desirable for aesthetic and economic reasons to group together in the same chest the two aprons of the shutters protecting said openings , the mechanisms being clean or shared. In this case, two consoles are used at each end of the box and to separate the two aprons, is used as a separating plate a part normally intended to act as cheek, but the outline is SPN004-FR-3 TEXT REMOVAL ACH 2905722 - 2 - cut to allow the assembly of the trunk and which is pierced to allow the assembly of the different mechanisms of each of the shutters. This solution means a lot of machining and requires to separate the two aprons 5 at least a distance equal to the thickness of the cheek used as a separating plate. This separation plate also requires tulips of different types of tulips used for the support plates acting as consoles. These different types of tulips 10 multiply the number of parts of the support device. The object of the present invention is therefore to overcome these various disadvantages, by proposing new parts and a new roller shutter mechanism support device making it possible to facilitate and reduce the assembly time, and in addition to optimize the spacing between the aprons, without increasing the number of parts used in the device. For this purpose, and in accordance with the present invention, there is provided a tulip for guiding an apron of a shutter and intended to be assembled to a mechanism support plate of the roller shutter, said tulip comprising a chute guide and a foot intended to be introduced with the support plate into a lateral guide slide of said apron, characterized in that said foot comprises a tab integral with the guide chute and a tongue disposed substantially parallel to the leg of the opposite side to the guide chute, said tab forming with the tab a housing for receiving the support plate, and in that there is provided in said housing means for positioning and holding the support plate in said housing. This construction makes it possible to assemble in a simple and safe way the tulip and its support plate. In a particularly advantageous manner, said SPN004-FR-3 TEXTE REMOVAL ACH 2905722 - 3 - positioning and holding means are arranged to receive in said housing a support plate of at least two different thicknesses e1 and e2, e2 being superior to el.

The tulip according to the present invention then has the advantage that it can be used with support plates of different thicknesses, which makes it possible to have a single type of tulip for several ranges of support plates and therefore for several ranges of shutters. rolling.

The present invention also relates to a roller shutter mechanism support device, characterized in that it comprises at least one tulip as described above and at least one mechanism support plate of said roller shutter arranged to cooperate with such a tulip. The support plates of the device may further have a thickness el or e2. Such a device can be used to separate at least two roller shutter decks within the same trunk, and then comprises at least two support plates of thickness el or e2 constituting separation plates for separating said aprons. Thickness support plates used as separating plates are ready for use and do not require machining prior to assembly. In addition, the use of two support plates as separating plates makes it possible to remove the cheek used as a support plate and to reduce the spacing between the two aprons and thus to thin all the parts 30 mounted in the trunk . Other advantages and features will become more apparent from the following description of a tulip and a roller shutter mechanism support device according to the invention, given by way of non-exemplary example.

The roller shutter mechanism support device 3 according to the invention can be used in different configurations depending on the number of aprons 50 integrated in one and the same trunk 4. When the trunk 4 contains only one apron 50, the device 3 comprises, for example, two support plates 2a used as consoles, and introduced with their tulip 1 into two simple lateral guides 7 of the apron 50, each slide 7 being turned towards each other and away from the width of the apron 50, as shown in Figure 13. When the trunk 4 contains two separate aprons 50, including different heights, the device 3 comprises for example two support plates 2b used SPN004-EN-3 TEXT REMOVAL ACH 2905722 - 12 - as separating plates, arranged back to back and introduced with their tulip 1 in two simple lateral guiding slides 7 of the apron 50, said slides 7 being arranged back to back, either against each other, or 5 spaced apart from each other depending on the desired spacing between the two aprons, in the case for example of an angular coupling of the two aprons 50. The assembly of the support plate 2 / tulip 1 assembly in a simple slide 7 is illustrated in FIGS. 8 to 10. The simple slide 7 comprises a chamber 8 in which a single support plate 2 / tulip assembly is introduced. 1, and a single channel 9 in which is guided a single apron 50. In Figures 8 and 10, the tulip 1 according to the invention is mounted with a support plate 2a of thickness e2, the connecting lug 24a being inserted in the housing formed by the lug 10 and the tongue 11. In this case, the first protrusion 13 and therefore the second protuberance 17 are engaged in the guide groove 15, the lug 14 is engaged in the opening 16, and the locking pin 22 is fitted into the orifice 23. The connecting lug 24a of thickness e2 then occupies all the housing 12 also of thickness substantially equal to e2 and is perfectly maintained in the tulip 1, one side against the tab 10 and 25 on the other side against the tongue 11. The support plate assembly 2a / tulip 1 is then introduced into the chamber 8 of the slide 7 by sliding the tab 10 of the tulip 1 between the guide rails 25 provided in the chamber 8.

In FIG. 9, the tulip 1 according to the invention is mounted with a support plate 2b of thickness e1, the connecting lug 24b being inserted into the housing formed by the lug 10 and the tongue 11. In this case, only the second protuberance 17 is engaged in the groove of the guide 18 and the locking pin 22 is fitted into the orifice 23. The connecting lug 24b of thickness e occupies then only the remaining housing between the lug 14 and the first protrusion 13 on the one hand and the lug 10 on the other hand, of thickness substantially equal to el. The connecting lug 24b is perfectly maintained in the tulip 1, one side against the lug 10 and the other side against the lug 14 and the first protrusion 13. As before, the support plate 2b / tulip assembly 1 is then introduced into the chamber 8 of the slide 7 by sliding the tab 10 of the tulip 1 between the guide rails 25 provided in the chamber 8. As shown in FIGS. 8 and 13, the clips of FIG. assembly 28 are mounted on the support plate 2a. They can be mounted in the same way on a support plate 2b, since they can be used independently of the thickness of the support plate 2a or 2b. Indeed, the wall of the support plate 2b of thickness e1 is introduced into the guide 33 and in the space of width substantially equal to el formed between the side wall 30 and the notches 32 of the assembly clip 28, or the wall of the support plate 2a of thickness e2 is introduced into the positioning finger 31 and into the space of width substantially equal to e2 formed between the side wall 30 and the central body 29 of the assembly clip 28 The box 4 is then assembled around the support plates 2a, or 2b, by screwing the profiles of the box 4 into the base 40 of the assembly clips 28 by means of self-tapping screws 52.

When the box 4 contains two separate aprons 50, of the same height, the device 3 comprises for example two support plates 2b used as separating plates, arranged back to back and introduced with their tulip 1 in a lateral guide slider SPN004 -FR-3 TEXTE DEPOSE_ACH 2905722 - 14 - 50 double deck 54 comprising a single chamber 8 receiving the two support plates 2b and their tulips 1 and two channels 9 arranged back to back on either side of the chamber 8 and in each of which is guided each apron 50. It is obvious that the support plates 2a of thickness e2 can be used, identically, as separating plates. The assembly of the support plate 2b / tulip assembly 1 in a double slide 54 is illustrated in FIGS. 11 and 12. As previously described, each of the connecting tabs 24b is inserted into the housing formed by the tab 10 and the tongue 11 of each tulip 1. In each tulip 1, each connecting lug 24b of thickness e then occupies only the housing remaining between the lug 14 and the first protrusion 13 on the one hand and the lug 10 of on the other hand, of a thickness substantially equal to el. Then the assembly comprising the two support plates 2b and the two tulips 1 is introduced into the chamber 8 of the double slide 54 by arranging each tab 11 of each of the tulips 1 back to back and by sliding the tab 10 of each Tulip 1 between the guide rails 25 provided on each bottom of the chamber 8. The spacing between each of the separating plates 2b arranged back to back is very small, and equal to the thickness of the two tabs 11 and the first two. 13. As shown in FIG. 11, this spacing between the two partition plates 2b arranged back to back is maintained by means of the assembly clips 28 which are used as separating clips, each separating plate 2b being introduced between each side wall 30 and the central body 29 of said clip 28. The box 4 is then assembled around the support plates 2b by screwing the trunk sections 4 SPN004-EN-3 TEXT REMOVAL ACH 2905722 - 15 in the base 40 of the assembly clips 28 by means of self-tapping screws 52. The various configurations of use of the roller shutter mechanism support device 35 described above can be combined to use for example in the case of a box comprising two separate aprons 50, two support plates 2a of thickness e2 used as consoles and two support plates 2b of thickness e1 used as separating plates 10 introduced in a double slide or in two simple slides arranged back to back either against each other or distant from each other. The above description clearly shows that the tulip 1 according to the invention can be associated with both a support plate 2b of thickness e1 and a support plate 2a of thickness e2. The roller shutter mechanism support device according to the invention thus comprises a limited number of parts since only one type of tulip is now necessary to mount all the support plates, used as consoles or as separation plates, and whatever their thickness. In addition, the separator plates are supplied ready-to-use and do not require pre-machining. Finally, the separation plates arranged back-to-back in a double slider make it possible to reduce and optimize the spacing between two separate aprons of a roller shutter used in the same trunk. The present invention applies more particularly to roller shutters fitted to windows or doors, but it is obvious that the examples which have just been given are only a particular illustration in no way limiting as to the areas of operation. application of the invention.
