Description

Roller shutter with mobile slats.

Technical sector of the invention

The invention relates to a blind Rollable with mobile slats, adjustable around an axis longitudinal, which is attachable to the frame of an opening in a building and winding on a winding drum rotary.

Background of the invention

Realizations of roller blinds attachable to the window or opening frame murals composed of a plurality of slats, formatted essentially rectangular, the ends of which are housed in corresponding U-guide profiles, having the slats turning capacity around its longitudinal axis between opening positions, in which the slats adopt the position essentially horizontal, and closing, in which the slats adopt an essentially vertical position. In this way, it can be regulated the passage of solar radiation or air through the window or the wall opening in which the blind is installed.

To achieve the rotation of the slats, these are conventionally endowed in its longitudinal ends of respective protrusions that are attached to a mechanism that connects all the slats and allows the simultaneous rotation of the slats to be User operated.

The main drawback of the solution before described to modify the orientation of the slats around its longitudinal axis is that, in order to vary said orientation, it requires the total development of the blind, that is to say that the all the slats must be arranged in the profiles U-shaped guide, so it is not possible to turn the slats when the blind is partially developed.

Patent document ES2162571 describes a shutter that solves the inconvenience described above. Bliss blind comprises both vertical sides of the wall opening two vertical guide guides, one fixed and one mobile, of U-shaped cross section, joined by a plurality of articulation devices, both profiles being guide, fixed and mobile, coplanaries with each other and being the guide profile movable mobile with respect to the fixed guide profile, so that it can move away and approach it following a resulting path of the combination of a horizontal translation movement and a vertical lifting or lowering movement, staying in all moment parallel to the fixed guide profile.

Each of the slats is endowed in each of its ends of two guide pins, one upper and the other bottom, which run inside the fixed guide profiles and mobile, respectively, to the extent that said slats are unwound. Thus, finding the total blind or partially developed, when the mobile guide profile is displaced, this one drags in its movement of simultaneous way to all the slats whose lower guide pins are inserted in the mobile guide profiles, which produces the rotation of the slats around its upper guide pins.

Its first objective is the present invention, ensure that the aforementioned upper guide pins and lower arranged at each end of each blade introduced in the respective fixed and mobile guide profiles, tailored that the blind is developed, in a simple and safe way.

Another object of the invention is to improve the drag of the slats when the guide profiles are displaced mobile, in the direction away from the fixed guide profiles, of so that all the slats are displaced uniformly since has observed that in the embodiments as described in the Patent document ES2162571, especially when profiles mobile guide perform a lifting movement virtually vertical, the lower guide pins slide down on the inside of the guide and consequently the slats do not reach to adopt an essentially horizontal position.

Explanation of the invention.

The rolling shutter object of the invention It is provided with two pairs of vertical guide profiles, each of which consists of a fixed guide profile and a mobile guide profile that determine two lanes, each pair of guide profiles being  intended to be mounted within the framework of an opening of a building, such as a window or a door, so that the two profiles guide of each couple are included in the same plane and that the mobile guide profile is attached to the corresponding fixed guide profile by at least one articulated device that allows you to perform in that plane alternative movements of separation and approach with respect to the fixed guide profile horizontally, comprising the blind a plurality of equal horizontal slats and linked together by respective articulated links of link arranged at its ends, being the set of slats Rollable and developable around a winding drum, each blade being provided at its ends with respective pins guiding, one upper and one lower, adapted to slide alternative and respectively upstream and downstream inside the rails of the fixed and mobile guide profiles when the corresponding slat is unwound, each pin being of guided upper articulated to a corresponding lateral link of linkage with which the displacement of the mobile guide profiles produces a simultaneous turning movement of the unwound slats around its upper guide pins.

In essence, the blind is characterized because the lower guide pins are longer than the width of the lateral link links, and because in the area the upper end of each pair of guide profiles is arranged a spreader nozzle of the pins, endowed in the wall from the bottom of the fixed guide profile of a downward ramp towards the mobile guide profile, whose mouthpiece is arranged at a height lower than that of the mouth of the fixed guide profile, and that die on the inner wall of it, adjacent to the mobile guide profile, each ramp being destined to receive end support free of the lower guide pins of the slats that are developed and to accompany them to the mouth of the guide profile mobile.

According to another characteristic of the invention, from the lower end of each ramp extends without solution of continuity and down a flat partition, in solidarity applied to the corresponding inner wall of the fixed guide profile, that reaches a height below the mouth of the profile mobile guide, with the partitions destined to receive support of the free end of the lower guide pins of the slats which are unwound and to accompany them until they are deposited in the inside the lane determined by the mobile guide profile.

According to another feature of the invention, the slats are provided at each end with a cover, solidly fixed to the slat and provided at its lower end of the lower pin and protrusion protruding down with respect to said cover and which is adapted to be facing the inner surface of the outer wall of the profile movable guide, said longitudinal section protrusion being oblong so that when the plank adopts the position essentially vertical, which corresponds to the position of maximum approach between fixed and mobile guide profiles, the protuberance is separated from said inner surface of the External rail wall of the movable guide profile, while when the slat exceeds a predetermined inclination, the bump rubs against said inner surface of the outer wall of the profile mobile guide

In a preferred embodiment, the movement of separation of the mobile guide profile from the fixed guide profile is the movement resulting from the combination of a movement of horizontal translation and a vertical lifting movement, and the approach movement of the mobile guide profile with respect to Fixed guide profile is the movement resulting from the combination of a vertical descent movement and a translation movement horizontal.

According to another characteristic of the blind, the lateral link links are articulated hooked together forming a side chain and each link is provided with a groove adapted to receive the housing of the corresponding lower guide pin, when the blind is wrapped around the drum of
winding

According to a particularly interesting variant, the maximum thickness of each link side link is greater than the maximum thickness of a slat.

Detailed description of the drawings

The blind 1 shown in Figs. 1a, 1b and 1c and in Fig. 2 comprises, in a known manner, two pairs of guide profiles of which only one has been represented in said Figs. 1a, 1b and 1c and Fig. 2. Of the pair of guide profiles represented, the guide profile 5 corresponds to a fixed guide profile while the guide profile 6 is a mobile guide profile, attached to the guide profile 5 fixed by a plurality of devices articulated, not represented, that allow you to make movements of distance or approach with respect to the fixed guide profile 5. The trajectory of said movements of distance or approach result from the combination of a translation movement horizontal and of a vertical lifting movement, and of the combination of a vertical descent movement and a movement of horizontal translation, respectively.

Each of the two fixed and mobile guide profiles 5 6 comprises a generally U-shaped opening that determines a lane 5c and 6c, respectively (see Figs. 1a, 1b and 1c), whose function will be explained later. Each pair of guide profiles is intended to be mounted within the framework of an opening of a building, such as a window or a door, facing another pair of analogous guide profiles and mounted on the opposite frame of The window or door.

The blind 1 comprises a plurality of slats 2 equal horizontals, which are linked together by respective links 7, 7 'articulated link arranged in their extremes and that are overwhelming and developable around a winding drum 12 (see Fig. 7). Each lama 2 is equipped with its ends of a corresponding cover 10, 10 ', each of which is provided with a pair of guided pins, one upper 3, 3 'and another lower 4, 4', adapted to slide alternative and respectively upstream and downstream inside lanes 5c and 6c of fixed guide profiles 5 and mobile 6 when the corresponding plank 2 is developed. Every upper guide pin 3, 3 'is articulated jointly to a corresponding side link 7, 7 'link with what the moving the mobile guide profiles 6 produces a movement of simultaneous rotation of the slats 2 developed around their 4 and 4 'upper guide pins.

In order to introduce the pins of upper guide 3 and 3 'and lower guide pins 4 and 4 'on the corresponding lanes 5c and 6c, respectively, for subsequently able to produce the rotation of the slats 2 and vary their inclination with the movement of the mobile guide profile 6, the 4 and 4 'lower guide pins have been provided with greater length than the width of the side links 7, 7 'link, so that they protrude laterally from the assembly formed by the plank 2, the corresponding end caps 10 and 10 'and the links 7, 7 '. The blind 1 is also provided in the area of the upper mouth of each pair of guide profiles of a nozzle for splitting the upper 3 and lower guide pins 4 of each plank 2.

In Figs. 1a, 1b and 1c and in Fig. 2 it is Note that each splitting nozzle is equipped with a wall of the bottom 16 of the fixed guide profile 5 of a ramp 8 in the direction descending towards the movable guide profile 6, whose mouthpiece 18 is arranged at a height less than the mouth 17 of the guide profile fixed 5. Said ramp 8 dies on the inner wall 5a of the guide profile fixed 5 (see Figs. 1a, 1b and 1c), adjacent to the mobile guide profile 6, and is adapted to receive support from the free end of lower guide pins 4, 4 'of the slats 2 which are developed and to accompany them to the mouth 18 of the profile mobile guide 6.

In the sequence shown in Figs. 1a, 1b and 1c, Fig. 1a shows a slat 2 in essentially position newly developed vertical and before the guide pins upper 3 and lower 4 are introduced in lanes 5c and 6c which determine guide profiles 5 and 6, respectively. In bliss Fig. 1a it is observed that when slat 2 descends, the free end of the lower guide pin 4 meets ramp 8. This situation is corresponds to that of the upper lama 2 of the representation in perspective of Fig. 2.

Starting from the position represented in Fig. 1a and in Fig. 2, if slat 2 is lowered, the pin of guided 4 will slide down ramp 8 and plank 2 will turn slightly. This situation is represented in Fig. 1b.

If the descent of lama 2 continues, the guide pin 4 will reach the end of ramp 8 and descend outside lane 5c determined by fixed guide rail 5, supported on the inner wall 5a thereof, until it is introduced into the inside of rail 6c through the mouth 18 of the profile mobile guide 6, see Fig. 1c, which is resting on the wall inside 5a of the guide profile 5.

In Fig. 3 it can be seen that from the end bottom of each ramp 8 extends without continuity solution and down a flat partition 9, jointly and severally applied to the corresponding inner wall 5a of the fixed guide profile 5, which arrives up to a height below the mouth of the movable guide profile 6, not shown, whose upper end is arranged supported on the inner wall 5a of the fixed guide profile 5 in zone 18 '. The partition 9 is intended to receive free end support of the lower guide pin 4 of the slats 2 during its descent and to accompany it until depositing it inside lane 6c of the movable guide profile 6. The thickness of the partition 9 prevents the lower guide pin 4 can bump against the upper edge of the mouth 18 of the guide profile 6, making its introduction difficult in lane 6c.

It is noted that the greatest length of lower guide pins 4, 4 'compared to length of said pins in known embodiments, solves another inconvenient to date not resolved. The length of the lower guide pins 4, 4 'as can be seen in Figs. la, 1b and 1c and in Fig. 5 is similar to the depth of lane 6c of the movable guide profile 6, so that the pins of guided 4, 4 'are introduced in lanes 6c practically to your back wall. Consequently, when each profile guides mobile 6 is moved away from the corresponding guide profile fixed 5, the guide pins 4, 4 ', which receive the thrust of the mobile guide profile 6, rest on the entire inner wall 6a of said profile and not only on its outer edge as It occurs in known embodiments. By not concentrating the force of reaction exerted by the lower guide pins 4, 4 ' on the corresponding mobile guide profile 6 at the edge of the inner wall 6a, during its push, a moment is not generated on said mobile guidance profiles 6 around their joints articulated with the corresponding fixed guide profile, so that articulated devices 11 joining both fixed guide profiles 5 and mobile are subject to much smaller bending efforts, what which facilitates the movement between the guide profiles.

By way of example, in said Fig. 3 it can be seen also one of the articulated devices 11, coupled to the profile fixed guide 5, designed to articulate the latter articulated to the profile Mobile guide, not shown for clarity.

In Figs. 2, 4a, 4b and 4c and in Fig. 5 it appreciate in greater detail that the slats 2 are endowed in their ends of respective covers 10 and 10 ', solidly fixed to lamas 2, each of which is provided at its end lower of said lower pin 4, 4 'and of a protuberance 13, 13 'protruding downward from said cover 10, 10 '. The protuberances 13, 13 'have a particular configuration oblong, adapted to bump against the inner surface 19 of the outer wall 6b of the guide profile 6 only when the blade exceeds  a predetermined inclination.

Indeed, in Figs. 4a, 4b and 4c has represented a sequence in which the slats 2 first adopt a slightly inclined position, an intermediate position and a essentially horizontal position, respectively. It can be seen in the Fig. 4a that the protuberances 13 face the surface inside 19 of the outer wall 6b of the movable guide profile 6, without get to contact the said interior surface 19. By the opposite, in Fig. 4b in which the slats 2 adopt a greater inclination, the same bumps 13 rub against the internal surface 19, while in Fig. 4c, in which the slats adopt an essentially horizontal position, which corresponds to the position of maximum distance between the profiles fixed guide 5, not shown, and mobile 6, the bumps 13 contact and even lightly press surface 19 of the outer wall 6b of the guide profile 6. This fact guarantees that lower guide pins 4, 4 'do not slide inside of lane 6c when the mobile guide profile moves according to a essentially vertical direction and that instead are dragged by the mobile guide profile 6 during said displacement, together with lama 2 to which they remain attached the lower guide pins 4, 4 '. Thus, when moving the mobile guide profiles 6, all the slats 2 whose pins of guided 4, 4 'are inserted in the rails 6c turn simultaneously, without losing its parallelism, adopting the same inclination.

In Fig. 5 a variant of the blind according to the invention, in which the inner surface 19 of the outer wall 6b of the movable guide profile 6 is provided with a non-slip material, such as a rubber, that increases even more the friction between the protuberances 13 and the determined rail 6c by the mobile guide profile 6.

While the solution of coating said surface interior 19 with a non-slip material, such as coating or partially or totally cover the corresponding counter surface to the inner surface of the inner wall 6a of the same profile mobile guide 6 (variant not shown) are a complement to the solution to provide with the protuberance 13 to the pins of guided lower 4, 4 'to avoid sliding down the rail 6c when the slats 2 adopt an almost horizontal position, also it is envisaged that said coatings can replace the solution of the protuberances 13, and that these are the only ones non-slip means incorporating blind 1 to produce the described effect

In Figs. 6a and 6b has been represented in profile a strip 2 and its corresponding cover 10, whose pin upper guided (not visible) is articulated jointly to the corresponding link 7, according to two different inclinations of the lama 2. In said Figs. 6a and 6b it can be seen that the thickness of the link 7 is greater than that of lama 2, so it is susceptible to be completely hidden behind link 7. It is also note that link 7 is provided with a groove 15 adapted for receive in the situation described above the accommodation of the corresponding lower guide pin 4.

This feature allows when the shutter is wrapped around the winding drum 12, as shown in Fig. 7, the guide pins lower 4 are housed in slots 15 being protected against the pressure that links 7 of the 2 slats superimposed or rolled to a higher level of the winding The bulk of links 7 also ensures that the 2 outermost slats overlap the inner 2 slats, being supported the links of the first on the links 7 of the second, without damaging the profile that constitutes each lama 2.
