Description

Roller blind device.

Object of the invention

The present invention, as expressed in the set forth in this specification, refers to a device of roller blind designed to be installed in correspondence with the glazed surfaces of windows and the like, so that the curtain itself can frontally cover a part or all of the glazed surface and also leave free that glazed surface. In this case the curtain will be fully folded and rolled in a winding drum that It is part of the assembly of the device of the invention fixed in the highest part of the corresponding surface glazed

Starting from this premise, the device roller blind comprises characteristic means for fix the curtain device assembly.

It is essentially applicable to windows and doors glazing, although its application can also be extended to other glazed surfaces.

Background of the invention

The devices are currently known of curtain applicable to glazed surfaces (windows of airplanes, trains, glazed windows and doors, etc.) to be able to cover these partially or completely, existing also the possibility of freeing all that surface glazed, this case in which the curtain is fully folded in a winding drum coupled by its ends in a few pockets, through which the device set. This also incorporates a front frame of protection set on the pockets that assemble the whole of the device.

The curtain can go up and down by chain or by means of a spring mechanism located inside the drum of winding. In this case a position is completely possible open or a fully closed position, although you can also obtain different intermediate positions by placing stops in the side guides at different heights to reach those stably positions.

On the other hand, they are currently manufacturing frames with 1 meter in length while the fabric of curtain must have a somewhat smaller width, which is around 98 centimeters. This is because in this way it prevents the side edges of the curtain come into contact with any part of the front and avoid braking and a bad operation of the curtain during folding and unfolded.

Description of the invention

The roller blind device that constitutes the object of the invention is determined from about extreme ends and a frontal protection frame that arms the device assembly, within which a drum is located winding of the curtain itself, drum that is engages in the front doors with interposition of a pair of supports ends, one of which is associated with a spring mechanism conventional so that the curtain pick-up is automatic, being necessary to overcome the resistance of this mechanism spring during deployment, driving the curtain in guides arranged on both sides of a surface glazed window, glass door or other surface Similary.

Obviously, the whole device is fixed in correspondence with the highest part of the surface glazed, which may be partially or fully covered with the aforementioned curtain The glazed surface will be completely free when the curtain is folded inside the device.

It is characterized because the device is fixed on the glazed surface itself through a couple of pieces  anchor, on which tabs are embedded solidarity of the testeros.

The aforementioned anchor pieces are fixed to the glazed surface by a strong adhesive.

The spring mechanism comprises a characteristic ratchet that has a portion embedded in a hole  complementary to the respective tester and another circular portion where the corresponding one is rotatably coupled, support for allow rotation of the winding drum.

On the other hand, another feature of the invention is that the testeros incorporate additional seats where they can support the extreme supports during their turn and the winding drum rotation which rotate together, thus achieving greater stability.

On the other hand, it should be noted that the structure of the described device allows to cut the winding drum and curtain rolled together with the same width without there is a danger of friction of the lateral edges of the Curtain on the heads. The width of the protection frame it will also be the same as the curtain fabric and drum of winding

In this way it is possible to manufacture bars Tubular (winding drum) of great length with fabric rolled and then cut together to the desired size Both related items. The frame profile can also be cut simultaneously with the drum and rolled fabric with it length.

In this way a great saving of Production and ease of assembly.

Next to facilitate a better understanding of this descriptive report and being an integral part of the same accompany some figures in which with character illustrative and not limiting the object of the invention.

Figure 4.- Shows a perspective view exploded from another part of the device of the invention.

Description of the preferred embodiment

Considering the numbering adopted in the figures, the roller blind device comprises in beginning a front frame 1, at whose ends two are fixed test heads 2 where a winding drum 3 of one is coupled curtain 4, winding drum 3 that engages in the testeros 2 with interposition of extreme supports 5 and 6, of so that one of them 5 is associated with a spring mechanism 7 which incorporates a ratchet 8 with a portion 9 embedded in a hole complementary 10 of the respective tester 2. Another circular portion 11 of the ratchet 8 is housed in a recess of the respective support 5 to allow its rotation together with the drum of winding 3 and the other even support 6.

The roller blind device is fixed at the highest part of a glazed surface 12 bordered by the frame 13 of a window 14 or similar, so that the 2 guards limit the total width of the glazing 12, contacting such heads 2 with facing areas of the sides of the frame 13 of the window 14, sides on which they are fixed guiding profiles 15 of the curtain 4 during folding and unfolded.

The testeros 2 have a pair of tabs 16 that are embedded in complementary boxes 17 of some angular anchoring pieces 18 fixed to the glazed surface 12 using a strong adhesive.

In turn, the tabs 16 have a stud. 19 liable to fit into one of several indentations aligned 20 established in one of the walls of the recesses 17 of the anchoring pieces 18. In this way the device Curtain can be adapted to windows with different depth of glazing 12 with respect to the front surface of the frame 13 of the respective window 14.

The front 2 incorporate some seats additional 21 where they can support the end brackets 5 and 6 during its rotation and the rotation of the winding drum 3 which rotate: together, thus achieving greater stability in the movement.

On the other hand, it should be noted that the structure of the described device allows to rotate the winding drum 3 and curtain 4 coiled together with the same width without that there is a danger of friction of the lateral edges of the curtain 4 on the front doors 2. The length of the frame 1 will be also the same as the curtain fabric 4 and drum of winding 3.

In this way it is possible to manufacture bars Tubular (winding drum) of great length with fabric rolled and then cut together to the desired size. He frame profile can also be cut simultaneously with the drum and rolled fabric.

This achieves a great production savings to while a great ease of assembly is achieved.
