Definitions
- the invention relates to a lateral strap outlet part for a roller shutter intended to be mounted on a trunk containing a flange pulley on which the strap is wound.
- maneuvers for rolling shutters fall into three categories: maneuvers by crank or winch, maneuvers by electric motorization and maneuvers by strap and cord.
- maneuvers by strap are done either at the underside of the boot containing the flange pulley or at the side outlet of said boot.
- the lateral strap outlet is used in the case where the operating strap on the underside outlet obstructs the opening of the window sashes.
- the operation by strap consists of a chest containing a flange pulley on which comes to wind the strap when the flap or apron is in the lowered position and a reel positioned on the window joinery in which comes rewind the strap when the flap or apron is in the raised position.
- the connection between these two reels is made by the passage of the strap through the wall of the trunk containing the flange pulley. This passage is carried out, at the side outlet, using a system for deflecting the strap mounted on the side wall or cheek of the boot and called the side strap outlet part.
- One of the widely used current solutions consists of a lateral strap exit piece composed of two elements each composed of a yoke and a free roller or roller.
- the outer yoke is screwed using three screws on the cheek of the trunk so as to position the roller down and the inner yoke is glued to the outer yoke by means of a flange so as to position the roller to the top.
- the inner screed 2 is screwed using three screws on the cheek of the trunk so as to position the roller down and the inner yoke is glued to the outer yoke by means of a flange so as to position the roller to the top.
- the strap can be tilted relative to the outer yoke. In this way, the strap is oriented to limit the angle of deflection between the flange pulley and the outer yoke.
- the strap crosses the strap exit piece passing between the roller in the high position and the inner yoke then between the roller in the lower position and the outer yoke.
- this solution mainly consists of four parts that must be assembled and positioned relative to each other and on the cheek of the trunk.
- Such a solution is therefore restrictive and costly for implementation.
- the object of the invention is therefore to modify the structure of these known lateral strap exit parts in order to limit the efforts to be provided by the operator during the various operations of raising and lowering the apron and to provide a system for simple and inexpensive work.
- a lateral strap exit piece for a roller shutter intended to be mounted on a chest containing a flange pulley on which the strap is wound, such that said piece consists of a single element passing through the wall of said trunk and whose end oriented towards the outside of the trunk is circular.
- the circular outlet allows the free movement of the strap around the circumference of the circle.
- the end oriented towards the outside of the circular shaped trunk is in the form of a flange with rounded edges, said flange bearing on the edge of the hole passing through the wall of the trunk.
- This embodiment makes it possible to avoid a significant protrusion of the strap outlet part relative to the wall of the trunk.
- the rounded edges of the collar make it possible to obtain contact of the strap with the strap outlet part according to a curved surface and not on an angular edge which would generate wear by friction of the strap.
- the friction of the strap is limited during the maneuvers and therefore the effort to be provided is reduced.
- the central part of the lateral strap outlet part is cylindrical.
- central part is meant the part of the part through which the strap passes. In this way, the orientation and movement of the strap remain free inside the strap outlet part.
- the end of said part facing the interior of the trunk is partially closed. Such an embodiment improves the air permeability and the acoustics of the trunk.
- the non-closed area of the end oriented towards the inside of the trunk forms a light over at most 180 °.
- An opening of at most 180 ° makes it possible, advantageously, to fix the part on the wall of the trunk in a single orientation, regardless of the size of the trunk used.
- the edges of the non-closed area of the end oriented towards the inside of the trunk are rounded. So we avoid, in the same way as for 4 known, it is no longer necessary to provide the inclination of this end to limit the angle of deflection of the strap.
- the edges of the non-closed area of the end oriented towards the inside of the trunk are rounded. In this way, the appearance of friction generating premature wear of the strap and forces is avoided, in the same way as for the end oriented towards the outside of the trunk.
- said lateral strap exit piece snaps from the outside onto the wall of said trunk.
- said installation of said part is simplified and eliminates the screwing, gluing and positioning operations which were necessary for the known strap output parts.
- the internal surface of said strap outlet part is polished. In this way, the friction between the workpiece and the strap is reduced.
- a workpiece polish is obtained, for example, by polishing the mold surface.
- the lateral strap exit piece according to the invention makes it possible, as explained above, to limit the efforts to be provided by the operator during the maneuvers of raising and lowering of the apron whatever the position of said operator. It also makes it easier to set up and implement it while reducing its cost price.
- this part is adaptable to the different sizes of existing trunk.
- FIGS. 1, 2 and 3 represent:
- Figure 1 a vertical section of a side strap exit piece according to the prior art mounted on a trunk
- FIG. 7 Figure 2 a vertical section of a side strap outlet piece according to the invention mounted on the same box
- 7 Figure 3 a front view of the side strap outlet piece according to Figure 2.
- Figure 1 shows the strap exit part 1 according to the prior art that we have described above. It is mounted in the lower part of the 5 plays 2 of a box containing a flange pulley, said flange pulley 3 being mounted on an axis 4 of rotation. The strap 5 is wound on the flange pulley 3 when the apron, not shown here, is in the lowered position and crosses the cheek
- the strap outlet part 1 is composed of an outer yoke 6 provided with a free roller or roller 7 of output and an inner yoke 8 provided with a free roller or roller 9 d 'Entrance.
- the outer yoke 6 is screwed to the cheek 2 of the trunk by means of three screws not shown and the inner yoke 8 is glued to the outer yoke 6.
- the strap 5 then passes between the input roller 9 and the inner yoke 8, then between the outer yoke 6 and the output roller 7.
- the two rollers 7 and 9 being in free rotation, the maneuvering forces are low.
- Figure 2 shows the piece 1 0 strap exit according to the invention.
- the strap exit piece 1 0 composed of a single substantially cylindrical element, is snapped onto the cheek 2 of the trunk from the outside using two snap-on elements 1 1 and 1 2.
- the end oriented towards the outside of the trunk is circular and forms a collar 1 3 with rounded edges resting on the edge of the hole passing through the cheek 2 of the trunk. In this way, the orientation of the strap 5 is much freer compared to that of FIG. 1. It is observed that the projecting external part of the piece 1 0 of strap exit is much less important than that of the piece 1 of strap exit, which brings an advantage on the esthetic level.
- the inner part of the strap exit piece 1 0 is shallower than that of the strap exit piece 1, which reduces the deviation of the strap 5 inside the boot.
- FIG. 1 shows a front view of the strap exit piece 1 0 according to the invention without strap 5. It is thus observed that the passage 1 5 forms a light over 1 80 ° so as not to limit the angle of deflection of the strap 5 between the flange pulley 3 and the piece 1 0 of strap exit.
- the strap outlet part 10 according to the invention is produced by molding a plastic material such as, for example, a polyamide-based material.
- This type of strap outlet part thus described makes it possible to limit the efforts to be provided by the operator during maneuvers. Its installation is really simplified thanks to the click system. In addition, this part improves the aesthetics of the strap outlet and is easy to make.
- the invention is not limited to this particular type of side strap exit piece and must be interpreted in a nonlimiting manner and encompassing any type of side strap exit piece for a roller shutter intended to be mounted on a chest containing a pulley. flange on which comes to wind the strap, said part consisting of a single element passing through the wall of the trunk and whose end oriented towards the outside of the trunk is circular.
