Description

Closure plate and tube holder roll up roller shutter.

The invention relates to a closing plate and support for roller shutter tube roller that means receiving means of a bearing rotating maintenance of one end of said tube of curl

The invention also relates to a blind roller that includes such a closing plate and support.

The present invention will find its application in The scope of roller blinds for doors, windows or Similary.

As usual, such roller blinds involve a board consisting of a juxtaposition of articulated sheets about each other, to wrap around a tube of curl The latter is positioned in an implanted drawer above an opening corresponding to a door, window or Similar in a building.

In a renovation solution, this drawer of roller blind can also be applied from the outside against the top of the carpentry, in particular the frame of such door or window.

The board winding tube is kept in rotation, at its ends, by closing plates and Support various designs.

In particular, this design depends on the implementation of the drive mechanism that allows control in manual rotation of this winding tube.

Thus, it is known to position a pulley of belt or chain drive, directly on the end of the winding tube, inscribing this pulley, by consequently, in the space between the two closing plates and support that keep the tube at each of its ends.

In such a configuration, the end of this tube of winding, opposite the drive mechanism, involves Often, a telescopic boom through which it cooperates with the bearing plate closure and support. So, by lace or axial disengagement of this end of the corresponding bearing, is it is possible to remove the mechanism assembly from its drawer Rolling up the roller blind without it being necessary completely disassemble the latter.

This solution, called below lace axial winding tube of roller blind, presents the drawback that the drive mechanism, for example, a drive pulley must be implanted in the vicinity immediately from one end of the winding tube, between the latter and the closing and support plate. In particular, this mechanism of Drive cannot be sideways deflected. Thus, it often occurs that the belt or chain, by which a user can act on this drive mechanism pulley, it place, on the inside of the house, in the leaf area corresponding to the door or window. In short, the belt, even the crank of a winch may hamper the opening of This sheet.

To alleviate this problem, it also knows, in this case of document FR-2,669,374, a roller shutter that behaves, housed in a drawer, plates designed closure and support capable of maintaining, at its ends, the Roll-up tube of this roller blind. In particular, by means of a U-shaped notch these plates of closure and support take the form of an open C in the direction of the rear face, which forms an inspection hatch, of the drawer of the roller blind. In this U-shaped notch comes slid, horizontally, a base that receives a bearing for Rotating maintenance of the winding tube. Through one of these bearings passes a drive shaft that connects a manual drive mechanism with said tube curl

In short, in this case, the mechanism of drive is no longer placed in the space between the plates of closure and support that keep the tube winding, but between such a closing and support plate and a plate side that closes, at one end, the drawer of the blind roller. In particular, this drive mechanism can be diverted laterally in the reserved space between this plate side and closing and support plate, to prevent the organ of maneuver, in this case a belt, a chain or a winch, obstruct, on the inside of the house, the opening of the leaf of a door or window.

To access the drive mechanism of the roller blind adopting such solution, just remove the face rear of the drawer that forms an inspection hatch. Through horizontal sliding, the bases are separated with their bearing, that keep the winding tube from the U-shaped notches in the closing and support plates. Drive mechanism which is connected to the winding tube by a Bearing a base obviously follows this movement. In sum, by means of this simple sliding operation, the whole of the Rolling shutter winding mechanism can be removed from its drawer without the need to completely disassemble, said roller blind. The interventions after the sale are obviously provided here.

Of course, as it follows from the description above, it is necessary that this extraction through The back side of the drawer is possible. Well, it is not always the case. In particular, depending on the conditions of implementation of the roller blind drawer above a window, only the Sofito is accessible. The latter then forms the trapdoor of inspection, that is, removable is planned to allow access to the inside of the drawer. If you are in the presence of a lace axial winding mechanism, this can effectively be removed from this drawer through this soffit. That raises the problem of the implementation of the drive mechanism with the consequences that have been set out above. Obviously yes the drive mechanism includes bases mounted so horizontally sliding in U-shaped notches of the plates closure and support, the fact that the back side of the drawer is not accessible imposes the total disassembly of the roller blind for to be able to intervene on this winding mechanism.

In figure 1 of the attached drawing comes illustrated a renovation type implementation that leads to constriction mentioned above. In this case, the front face A of the drawer B of the roller blind is oriented towards the exterior of the house, placing this front face A substantially in the vertical extension of the guides C which contribute to the lateral guidance of the panel of this blind roller. As for the rear face D, it is inserted in apply against the outer face of the door or window frame E, which makes it inaccessible.

Only soffit F can, if necessary, be disassembled by an operator, to access the inside of the drawer B.

The present invention aims to be able to solve this problem of accessibility to the mechanism of Rolling up the roller blind without disassembling the latter under implantation conditions as illustrated in this Figure 1. Therefore, the invention wants to avoid drawbacks that result from an axial fitting solution.

To this end, the invention relates first place, to a closing plate and support for winding tube of a roller shutter board that includes means of receiving a maintenance bearing in rotation of a end of said winding tube, characterized in that behaves, in its lower part and extending in the direction of its center, a notch, particularly intended for insertion and / or output of a drive shaft that connects, through said closure plate, a winding tube with a mechanism manual actuation, being the means of receiving a defined bearing, on at least one side of the closing plate, by means of fixing by axial engagement of said bearing.

The invention also relates to a blind roller that includes such a closing and support plate as well as a board winding tube that involves at least one end, a bearing provided with designed fitting means able to cooperate, in a complementary way, with fixing means by axial engagement that said closure and support plate entails, in At least one of its sides.

The advantages that result from this invention consist of the bearing, through which a closure and support plate keeps one end of the tube in rotation of winding a roller blind, it is axially fitted in said closure and support plate. Thus, having disengaged, axially, this bearing with respect to said closing plate and support, the whole roller winding mechanism Roller can be disassembled without difficulty.

Indeed, thanks to the oriented notches down on the closing and support plates, removing This winding mechanism can be done through soffit of the roller blind drawer. In particular, said notch authorizes the passage of the drive shaft that passes through the bearing and connecting the winding tube, disposed of a side of the closing and support plate, with respect to a mechanism of drive which, in turn, is positioned on the opposite side to this closing plate

It will be noted that, due to the axial engagement of the bearing on the closing plate, the load that represents the winding mechanism is perfectly transmitted to this closing plate, despite the presence, in the latter, of a notch oriented substantially vertically and downwards.

The present invention will be better understood by the reading the description that follows, which refers to an example of Embodiment illustrated in the accompanying drawings.

Figure 1 is a schematic representation and in section of a roller blind illustrated in the frame of a implantation that makes the back of the drawer of this drawer inaccessible roller blind;

Figure 2 illustrates, schematically and in perspective, a closure and support plate according to the invention which receives, on the one hand, a drive mechanism that acts on the winding tube disposed on the opposite side of this plate closing and maintained in rotation with respect to the latter by means of a Bearing;

Figure 3 is a schematic representation in perspective and breakdown of the visible pieces in the figure 2;

Figure 4 is a view similar to Figure 3, adopting the drive mechanism, here, in the form of a pulley, the spring-shaped spring being visible in this figure circlips that constitute, substantially, the blocking means axial bearing on a closing and support plate.

As you can see in the figures of the attached drawings, the present invention relates to the scope of roller blinds.

Such roller blind 1 includes a tube of curl 2 of a board (not shown) constituted, usually, of a juxtaposition of articulated sheets Regarding others. This board is capable of deploying in guides guiding sides C implanted on both sides of the opening corresponding to a door, window or similar E of which it is provided with roller blind 1.

The winding tube 2 is kept in rotation at its ends 5 by bearings 6 associated with plates of closure and support 7 arranged substantially in alignment vertical of the lateral guides C of which can be Solidarity by appropriate means of fitting and fixing 8.

A manual drive mechanism 9, represented in the form of a winch in figures 2 and 3 and of A pulley in Figure 4 is intended to allow a user control the winding tube 2 in rotation by, according to the case, a crank, a strap or a chain.

The set of these mechanism components of winding a roller blind 1 is positioned in a drawer B consisting of a front face A that is placed, substantially, in the vertical extension of the lateral guides C, a rear face D, a top wall G and a soffit F. At the level of the latter there is a slot H of the board of roller blind 1.

In Figure 1, this roller blind is illustrated in the frame of a particular implantation in front of a door or window E. In particular, the drawer B is, here, inserted in wall light, by its rear face D, against the outer face and at the top of the frame 10 of this door or window E. Therefore, the winding mechanism of such roller shutter
1 is essentially accessible through soffit F.

To resolve, particularly in such a situation in particular, the problem of dismantling the mechanism of winding, the closing and support plate 7 behaves, so advantageously, a notch 11 extending from the bottom 12 of this closure plate 7 in the direction of the center thereof. This notch 11 authorizes the passage of a drive shaft 13 which connects the drive mechanism 9, disposed of a side 14 of the closing plate and this closing plate 7.

The latter includes reception means 16 of the bearing 6 capable of keeping an end 5 of this rotating winding tube 2. According to the invention, these means of reception 16 are defined, on at least one of the sides of the closure plate and support 7, in the form of fixing means by axial fitting 17 of said bearing 6.

The latter involves lace means Complementary 18 to allow you to cooperate with these means of axial fitting 17. Preferably, the latter are provided on the closing and support plate 7 on its side 15 oriented in the direction of the winding tube 2. However, it can be also contemplate that such fastening means 17 are provided on the opposite side 14 of this closure and support plate 7,  even on each side 14, 15.

Substantially, bearing 6 is mounted on rotation on a piece of shaft 19 that ends, at the end 5, the winding tube 2.

It will be noted that the axial mobility of the bearing 6, to allow its fit or disengagement with respect to a plate of closure and support 7, may result from the disengagement of the opposite end of the winding tube 2 with respect to the corresponding plate of closure and support. In particular, at this opposite end, this tube winding 2 can be mounted on a piece of shaft telescopic, capable of being axially disengaged from such a plate of closing and support. It can also be contemplated that bearing 6 be movable axially, on the shaft piece 19 and / or that this last be telescopic with respect to the end 5 of the tube curl 2.

Fixing means by axial fitting 17 They can adopt different embodiments. So, they can presented in the form of a semi-cylindrical collar or, as It is illustrated in the drawings, in the form of several pins of lace 20 that extend substantially perpendicularly with respect to the closing and support plate 7. The fitting means Complementary 18 at the level of bearing 6 obviously adopt an adapted form, for example of housings 21 capable of receive these 20 lace pins, even a collar semi-cylindrical as indicated above. It will be noted, here too, that these housings 21 can be defined by notches in the bearing periphery 6, as visible in the mode of embodiment depicted in the accompanying drawings. However, it can easily contemplate bearing 6 substantially circular, these housings being 21 internal.

Intended are also blocking means 22 designed capable of locking the bearing 6 in the embedded position on the closing and support plate 7.

In particular, such locking means 22 can adopt, as visible in figure 4, the shape of a circlip 23 which is inserted into the bearing 6 so that it can occupy an unlocked position, be a locked position.

In this locked position, in which it is pushed by an elastic effect, this circlip 23 communicates with everyone or part of the housings 21 that receive the lace pins 20. The latter include a slot 24 designed capable of receiving this circlip 23, so that it comes immobilized in displacement axial bearing 6 on the closure and support plate 7.

Upside down, in unlocked position in which is brought under the effect of a voluntary action exercised by an operator, this circlip 23 is released from said slot 24 of the lace pins 20, authorizing the exit of the latter from their accommodation 21.

Advantageously, the circlip 23 is provided of at least one clamping ear 25, 26 accessible at the periphery of bearing 6 and by which or which an operator can act against its elastic recoil force, to push it into its unlock position and release your action on the pins of lace 20.

As is clear from the description that precedes and of the attached designs, once axially disengaged the bearing 6 with respect to the closing and support plate 7, the corresponding end 5 of the winding tube 2 can be separated from said closure and support plate 7. The shaft of drive 13 that connects drive mechanism 9 with this winding tube 2 can, in effect, follow the tube of curl 2 in this movement, thanks to the notch 11 provided for this purpose on the closure and support plate 7.
