Motorized screen group

Description

[0001] The present invention refers to a motorized screen group.

[0002] In particular the present invention refers to an automatically, but also manually upon occurrence, movable screen for the selective separation of environments.

[0003] According to an exemplified preferred embodiment, the screen of the present invention may be an anti-mosquito net.

[0004] However, in the present description, the term screen is generally used to indicate any type of separating element whether a net or not a net.

[0005] Currently screen groups are known comprising a first and a second upright movable with respect to each other starting from a first position of mutual contact, in which the screen is closed, to a second position of maximum distance, in which the screen is open.

[0006] These screens may be opened or closed by manually operating on the uprights, on which there some handles are actually obtained, or currently it is known to provide motors for automatically opening and closing.

[0007] Getting into detail of the most common embodiments available today, the screens are mostly of the type that can be wound around a roller housed in an upright.

[0008] Most of the drive means present therein are usually associated with such roller for controlling the rotation to roll and unroll the screen.

[0009] This embodiment, which derives from the automatic movement of roller shutters, however reveals the drawback of requiring considerable time intervals for moving the screen from the closed position to the maximum opening position.

[0010] In the attempt to overcome this drawback, a second type of automatic screens where the driving means are no longer connected to the winding roller but to other elements of the screen group is currently available in the market.

[0011] In particular a motorized screen is known where a driven belt provides for directly moving the uprights or doors.

[0012] However not even this embodiment is entirely satisfactory in terms of ease of assembly and maintenance of the screen.

[0013] EP2469009 discloses a motorized screen group according the preamble of claim 1.

[0014] An object of the present invention is to provide a motorized screen group representing an alternative to those currently available and that is efficient on the one hand and easy to assemble and maintain on the other hand.

[0015] These objects according to the present invention are attained by providing a motorized screen group as defined in claim 1. Further characteristics of a motorized screen group according to the invention are outlined by the dependent claims.

[0016] The characteristics and advantages of a motorized screen group according to the present invention shall be more apparent from the following exemplifying and non-limiting description with reference to the attached schematic drawing which shows an exploded embodiment of a motorized screen group according to the present invention.

[0017] Such motorized screen group 10 is of the type comprising a first 11 and a second upright 12 parallel to each other and a screen 13 having opposite ends associated with the uprights 11, 12.

[0018] As shown, the uprights are substantially vertical and made in form of metal uprights while the screen may preferably, but not exclusively, be an anti-mosquito net.

[0019] Both or at least one among the first and the second upright 11, 12 are movable starting from a first position of mutual contact, in which the screen 13 is closed, to a second position of maximum distance, in which the screen 13 is open.

[0020] For a better understanding of the term movable referring to the uprights 11 12 reference should be made to the external framework, per se known, in which the screen group 10 is installed.

[0021] This external framework comprises lateral counter-frameworks 19 and at least one upper cap 20.

[0022] The uprights are defined movable with respect to the aforementioned lateral counter-frameworks 19 if, when required, they can unconstrain therefrom to reach the required positions.

[0023] Thus, according to the present invention, all uprights that are not removably constrained with the relative counter-framework are deemed movable.

[0024] The presence of selective holding means, such as magnets, hooks, bayonets and others do not jeopardise the fact that the relative upright can be freed and moved.

[0025] Thus clarified, the figure shows magnets 21 as examples of the aforementioned selective holding means of the uprights in position with respect to the counter-frameworks.

[0026] Guiding means 14 for guiding the opening and closing of the screen 13 are provided associated with at least one free side of the screen.

[0027] As shown, the guiding means 14 are configured so that when the screen 13 is closed, they are substantially internally housed in the first upright 11 and when the screen 13 is open they are at least partially outside with respect thereto.

[0028] Solely by way of example, the shown guiding means are two opposite series of rigid hinged elements 14 but they could alternatively be any other type of guide such as for example an elastic band or of any other type.

[0029] The guides 14 are usually solely required to be able to pass from the horizontal extracted configuration to the vertical containment configuration inside the upright 11.

[0030] According to the invention, a motor 15 is provided for automatically opening and closing the screen group 10 where in particular such motor 15 controls the movement of the guiding means 14.

[0031] On the contrary, according to the prior art the motors currently available in the market for such screens are associated to the roller winder or to the uprights.

[0032] Thus, according to the invention, the motor 15 automatically controls the entry and exit movement of the guide 14 with respect to the first upright 11 and, indirectly, closing and opening the screen.

[0033] Preferably the connection between the motor 15 and the guiding means 14 is realized inside the first upright 11 and comprises a belt for transmitting motion from the motor 15 to the guide 14.

[0034] By way of example of the invention, the means for driving the group comprise a driven belt 17 operating, preferably in the upright 11 or externally parallel thereto, on at least one guide 14.

[0035] However in general the innovative aspect of the present invention lies in directly controlling - in a motorized manner - the guide 14 and not the roller 16 or the uprights 11 12.

[0036] Even more advantageously, the motor 15 is integral with the first upright 11 thus making the group easy to mount and demount.

[0037] In the shown example, the screen 13 is of the type that can be wound around a roller 11 housed in the second upright 12, but it could also be of the pleated type.

[0038] Lastly, the motor 15 can be controlled in actuation by providing for the presence of remote sensors or buttons or commands, of the remote controlled type power-supplied in any manner both of the renewable and conventional type.

[0039] The substantially vertically operating motorization also allows to obtain a modular system with a high number of doors.

[0040] On the contrary, using the prior art method which provides for the horizontal motorization, the maximum possible number of doors is two. Increasing the number of doors would actually provide for superimposed path sections of the door with the ensuing increase of the thickness of the structure.

[0041] It has thus been observed that a motorized screen group according to the present invention attains the objects outlined beforehand.

[0042] Actually, such motorized screen group offers a valid alternative solution to the currently known screens with considerable advantages in terms of ease of assembly and maintenance.

[0043] The motorized screen group of the present invention thus conceived can be subjected to many modifications and variants. In practice, the materials used, as well as the dimensions thereof, may be of any type depending on the technical requirements.
