Description

Tablet for adjustable blinds.

Scope

The present invention relates to slats  adjustable for blinds.

Significantly, the present invention relates to slats applicable to an adjustable slatted blind having a structure such that said slats can be oriented from an open position to a perfectly closed watertight

Background of the invention

The use of blinds provided with orientable slats, usually made with profiles extruded aluminum, which allow the brightness to be adjusted Inside a room

The movement of the slats can be done by means of a handle, which acts together with a profile, which operates a hinged bar on some support elements of the tablets that, in this way, can be oriented simultaneously according to the desired rotation.

This embodiment known in the art It is described, for example, in Italian Patent No. 1217619.

The support elements of the slats usually be of synthetic material and have very high dimensional tolerances low.

According to embodiments known in the technique, the movement of the slats can be obtained Likewise:

- with acting drive handles, directly or indirectly, on perforated metal rods that they connect rotating elements provided with bolts and joined together to the clamp brackets;

- by automatic devices that require, in this case, simply employment by the user of a dedicated control unit.

In the closed position the slats must be perfectly tight against atmospheric agents, noise and light.

Nowadays said tightness is obtained using boards placed in correspondence with the areas of top of the profiles of the slats, that is, where the slats are  unite and merge with each other.

Examples of realization of these tablets provided with a sealing gasket are described and illustrated in the said Italian patent n. 1217619, as well as in the patent Italian n. 1228374.

The boards provided with a joint described in these patents have the characteristic of guaranteeing a barrier perfect against the passage of light because the ones are coupled with the others forming labyrinth-shaped paths that represent a triple barrier against the passage of light when the slats They are in the closed position.

However, a first inconvenience of this kind The solution is that the use of joints requires maintenance newspaper and / or the replacement thereof, to which is added the fact that, being said joints made with materials synthetic, suffer shrinkage phenomena that harm the expected barrier effect, especially at the ends of splints

Another drawback is the fact that the builder of adjustable slatted blinds should be stored in the warehouse, in addition to the numerous spare parts, the gaskets of tightness

Another drawback is that the assembly of the Adjustable blind is very complicated due to the presence of many pieces and, specifically, the assembly of the joints in the tablets often lead to unwanted setbacks.

Lastly, the employment of waterproof joints entail expenses that have an impact on the final cost of the finished product, expenses linked to the cost of the board itself and to the labor costs necessary for the application of together on the tablets.

Description of the invention

The present invention aims to set arrangement of slats for adjustable blinds formed mainly by extruded aluminum profiles that allow obtain an optimal barrier against the passage of light by eliminating drawbacks mentioned above.

The present invention is also proposed provide a simple splint so that it results easily producible at an advantageous cost.

This is obtained with a slat board adjustable with the features of the claim principal.

The secondary claims describe forms of embodiment of the invention advantageous.

The slats for adjustable blinds according to the  invention provide for a hollow body that has, on both sides Opposites of greater length, locations and projections in different ways for coupling to other adjustable slatted slats, said projections are coupled at the respective locations allowing a tight seal thanks to perfect surface adhesion in contact, without the need to insert any gasket between a splint and other.

In accordance with the invention the slats they present, in correspondence with the outgoing, a guiding part Convex curvilinear towards the outside of the hollow body.

The tablets provide, in correspondence with the headquarters, a concave curvilinear cavity towards the outside of the body hollow and intended to accommodate the respective curvilinear guide part.

In the closing phase of the blind, the slats provided with outgoing and those provided with headquarters are oriented in angle until their sides are closer in length. At moment when said sides come into contact, the guide part curvilinear rests on the corresponding cavity guiding the outgoing to fit in the corresponding headquarters until get the sealing of the slats.

Advantageously the projection has a section cross-shaped triangle while its corresponding seat It is formed by a slot.

Advantageously the hollow body has nerves of reinforcement in correspondence with the ends provided with headquarters and outgoing

The perfect rapport of each projection in the corresponding headquarters excludes the use of gaskets, whereby the purposes of the invention are achieved; in fact, the surfaces in contact ensure the necessary adhesion and indispensable to avoid the penetration of substances in general, preventing the passage of light and ensuring good insulation acoustic.

Brief description of the drawings

Other features and advantages of the invention they will be evident when reading the following description in a way of embodiment of the invention, provided by way of example, non-limiting, with the help of the drawings illustrated in the table attached where:

- Figure 1 shows a perspective view of an orientable splint according to the invention; Y

Description of an embodiment

In the figures the reference number 10 indicates generally a splint for adjustable blinds with barrier function against the passage of light, provided with a partner of projections 11, 11 'whose function will be described below with details.

The splint 10 includes a delimited hollow body by a pair of surfaces 15, 15 'which, for example, can be parallel. The surfaces 15, 15 'constitute a good part of the splint 10 which on each of its sides of greater length presents a curvilinear guide part 16, 16 'convex outwards of the tablet itself 10.

Each surface 15, 15 'presents, in correspondence with a longer side, a cavity 17, 17 ' within which the respective protrusion 11, 11 'is attached that protrudes to a slightly lower level than corresponding surface 15, 15 '.

Each cavity 17, 17 'presents a part curvilinear 18, 18 'concave outward and joining the surface 15 with the respective projection 11, 11 'and a corresponding groove in the form of "V" 19, 19 'delimited by the guide part 16, 16' and by the projection itself 11, 11 '.

The latter advantageously presents a section cross shaped triangle.

The surfaces 15, 15 'are joined, in correspondence with each guide part 16, 16 ', by some ribs 20, 20 'intended to reinforce the splint 10.

The cross section of the splint 10 can have a configuration with central symmetry presenting the cavities 17, 17 'in their own opposite faces and in correspondence with the opposite sides of greater length.

With reference to figures 2a, 2b and 2c, shows a closing sequence of an adjustable blind provided  of the boards 10, 10 'mounted on supports similar to the described in the aforementioned Italian and powered patents by mechanisms analogous to those described in said patents.

For the purpose of this description is important to note only that the tablets 10, 10 'turn to same time around its center C, C ', and that the corresponding centers C, C 'of the slats 10, 10' lie normally in a straight line A which, in the mounted blind, is parallel to the vertical uprights of the blind.

During use and in the closed position of a blind provided with slats 10, 10 'a part of the section curvilinear 16 of the board 10 is inserted in the cavity 17 'of the splint 10 'located below. At the same time, a part of the section curvilinear 16 'of the splint 10' is inserted in the cavity 17 of the splint 10 located above.

In this condition the projection 11 of the splint 10 easily enters the corresponding slot 19 ' entering partially within its respective headquarters.

In such a way, the simultaneous contact of more alternately concave and convex curved surfaces, along with the coupling of the projection 11 at the corresponding headquarters, creates a maze-shaped path that ensures optimal closure without the Need to insert any gasket.

The slats 10, 10 'can be made of aluminum Extruded surface treated if appropriate, for example painted.

The invention has been described with reference to a preferred embodiment.

However, it is clear that the invention admits Many variants in the field of equivalent techniques.

By way of example, forms of embodiment of the invention in which surfaces 15, 15 'do not are parallel to each other as in the example illustrated above, but They have a convergent shape to each other.

In addition, surfaces 15, 15 'may not be flat as illustrated in the figures but have a section Curvilinear in several ways.
