Description

Title of the invention: Structure for roller shutter and its roller shutter TECHNICAL FIELD OF THE INVENTION

[0001] The invention relates to the field of structures for roller shutters, and more particularly to structures intended to be mounted in a window frame and which facilitate initial assembly, as well as subsequent actions such as repairs, readjustments or replacement of components. The invention also relates to a window shutter equipped with the structure. BACKGROUND OF THE INVENTION

[0002] Roller shutter structures comprising a tubular motor and end brackets of the tubular motor for attachment to a window frame or wall are well known.

[0003] The end supports can be simple substantially flat plates, L-shaped pieces, allowing them to be mounted at an angle, or three plates perpendicular to each other allowing them to be arranged in corners.

[0004] One of the problems with these systems is that decoupling the motor from the mounts must be done by removing the mount / motor assembly from the frame, which can damage the frame itself. Due to the deterioration of the frame, this can also mean that when reinstalling the mounts, the new assembly will not be aligned as the first time. DESCRIPTION OF THE INVENTION

[0005] In order to overcome the shortcomings of the prior art, the present invention proposes a structure for a roller shutter, comprising a tubular motor, end supports of the tubular motor intended to be fixed to a window frame or to a wall, the structure comprising intermediate mounting plates for mounting the tubular motor, the mounting plates being provided with bearing edges, the end supports being provided on one of their faces, called the inner face, with projections forming positioning stops, in an operational configuration, of the intermediate mounting plates relative to the end supports in cooperation with the bearing edges, the system being provided with means for locking the intermediate mounting plates relative to the end supports in the operational configuration.

[0006] This structure allows both safe and convenient initial assembly and safe and convenient subsequent repairs. The combination of the end supports and mounting plates allows for two-phase assembly: a first assembly phase of the motor to the mounting plates, for example by means of screws, and a second phase of fitting the assembly obtained between the supports and subsequent locking. Thus, the first step, more complicated because it may involve screws, is carried out outside its site of use. It is therefore more practical. The second step of fitting is also very practical, since only a single sliding operation between the supports is necessary. In particular, thanks to the invention, it is not necessary to carry out complicated assembly tasks in a more difficult-to-access place, such as the upper part of a frame or a window. Furthermore, if a replacement or overhaul has to be carried out, these are also very practical. Of course, the invention requires an appropriate dimension of the elements, that is, that the distance between the end supports corresponds to the distance (on the outer sides) of the mounting plates.

[0007] In some embodiments, the bearing edges and the projections define a direction of insertion of the intermediate mounting plates relative to the end supports and the locking means consist of a guide groove in the respective intermediate mounting plate, a stop projection on the inner face of the respective end support and a sliding part through the guide groove which can be moved between:

[0008] - an unlocked position in which it is fully inserted into the guide groove and in which the intermediate mounting plate can slide relative to the respective end support; and

[0009] - a locking position in which, in the operational configuration, it protrudes from the guide groove and rests on the stop projection.

[0010] This is a simple embodiment of the invention, since it is sufficient to machine the plate and provide a sliding part. Furthermore, it is not necessary to drill holes in the end support, the retaining projection being sufficient. Other locking mechanisms could be imagined, for example a pin whose direction is perpendicular to the plate and which cooperates with a hole in the support, or a screw.

[0011] In addition, the same end bracket can be used with multiple mounting plate designs.

[0012] In some embodiments, the intermediate mounting plates are provided with tubular motor mounting holes.

[0013] In some embodiments, the intermediate mounting plates are defined by an axial center coinciding with the motor axis, the center being provided with a shaft mounting hole or a protruding shaft.

[0014] In some embodiments, the tubular motor mounting holes are arranged in a ring relative to the center.

[0015] In some embodiments, the tubular motor mounting holes are angularly arranged and NOT equidistant, so that the initial angle of the motor can be adjusted.

[0016] In some embodiments, the guide groove comprises notches and the sliding part comprises projections, or vice versa, to cooperate with the notches, so as to define stable positions of the sliding part in the guide groove.

[0017] In some embodiments, the sliding part is U-shaped, such that two resilient tabs are defined to allow it to be deformed for insertion into the guide groove.

[0018] In some embodiments, the sliding part has a transverse projection intended to allow the user to actuate it.

[0019] Finally, the intermediate mounting plates are symmetrical with respect to their main plane.

[0020] The invention also relates to a window shutter comprising a structure according to any one of its variants and two side profiles mounted on end supports. Brief description of the drawings

[0031] As illustrated in [Fig.5], the invention relates to a structure S for a roller shutter P, comprising a tubular motor M and end supports 1 of the tubular motor M intended to be mounted to a window frame or to a wall.

[0032] According to the invention, the structure comprises intermediate mounting plates 2 for mounting the tubular motor M. These mounting plates are mounted to the motor before mounting the assembly to the frame.

[0033] These intermediate mounting plates 2 are provided with bearing edges 22, 23, 24. In addition, the end supports 1 are provided on one of their faces 11, called the inner face 11 (because it is oriented towards the engine), with projections 12, 13, 14 which form positioning stops, in an operational configuration, of the intermediate mounting plates 2 relative to the end supports 1.

[0034] This configuration is obtained by the cooperation of the projections 12, 13, 14 with the bearing edges 22, 23, 24 which, once in contact, allow, as illustrated for example in figures 1, 2 or 3, to mount the plate / motor assembly in its place. All that remains then is to mount the structure, for this locking means 3 of the intermediate mounting plates 2 are provided concerning the end supports 1 in this operational configuration.

[0035] As can be seen for example in [Fig.6], the bearing edges 22, 23, 24 and the projections 12, 13, 14 define an insertion direction X of the intermediate mounting plates 2 relative to the end supports 1.

[0036] In the embodiment illustrated in the figures, the locking means 3 consist of a guide groove 25 in the respective intermediate mounting plate 2, a stop projection 15 on the inner face 11 of the respective end support 1 and a sliding part 4 through the guide groove 25 which can be moved between:

[0037] - an unlocked position in which it is fully inserted into the guide groove 25 and in which the intermediate mounting plate 2 can slide relative to the respective end support 1, as shown in [Fig.6]; and

[0038] - a locking position, illustrated in [Fig.7], in which, in the operational configuration, it projects from the guide groove 25 and rests on the stop projection 15.

[0039] In the illustrated embodiments, the intermediate mounting plates 2 are provided with holes 21 for mounting the tubular motor M, arranged in a crown relative to the center 2C and, preferably, arranged angularly in a NON-equidistant manner so as to define different non-multiple positioning angles.

[0040] An axial center coinciding with the motor axis M is defined in the intermediate mounting plates 2, the center 2C being provided with a shaft mounting hole or a projecting shaft A, as shown in [Fig.3].

[0041] In the embodiment of the locking means illustrated in the figures, the guide groove 25 comprises notches 25m, and the sliding part 4 comprises projections 4r, as illustrated in [Fig.8], to cooperate with the notches, so as to define stable positions of the sliding part 4 in the guide groove 25. It can also be seen that the sliding part 4 is U-shaped, so as to define two elastic tabs which allow its deformation for insertion into the guide groove 25.

[0042] To facilitate the actuation of the part by the installer, the sliding part 4 is provided with a transverse projection 4t, as illustrated for example in [Fig.8].

[0043] The intermediate mounting plates 2 are symmetrical in their main plane, so that a single reference is sufficient for mounting on both sides.

[0044] As used herein, the term "includes" and its derivatives (such as "comprises", etc.) should not be understood as exclusive, i.e., these terms should not be interpreted as excluding the possibility that what is described and defined may include other elements.

[0045] Of course, the invention is not limited to the specific embodiments described herein, but also covers any variation which may be considered by any person skilled in the art to fall within the general scope of the invention as defined in the claims.
