Description

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, each of a plurality of thin plates vertically arranged in parallel with each other with an inner space therebetween can be fixed to a wall body by an upper fixed end. The thin plate body has an obliquely extending thin plate body, and the thin plate body has a lower fixed end formed of a lower groove that is opened toward the wall body.
A blind fixed to the wall, e.g. a facade, i.e. the front of the building, which forms the upper fixed end of the lower lamella located below the lamella containing this lower groove and faces the upper groove which once opens towards this lower groove Regarding

The embodiment described above is apparent in Figures 9 to 12 of DE 2910877. The front third wall body (hereinafter, also referred to as a front foundation structure) is provided with vertically extending grooves, is formed as a rail, and is composed of vertically arranged support members. A cantilever arm for holding the thin plate at at least two places is inserted into the groove and has a leg portion which is in contact with the supporting profile and a leg portion which stands upright from the supporting profile. The downwardly bent free end of the right-angled leg engages an upwardly opening groove provided on the lower surface of the lamina. The upper groove of each lamella is formed in a generally circular cross section and has an outer contour with a flat contact edge. This contour corresponds substantially to the inner contour of the above-mentioned hook-shaped web of the cantilever arm. To assemble the thin plates, the upper fixed end of each individual thin plate was bent into the hook-shaped web of the cantilever arm, and the holder arranged on the lower surface of the thin plate main body was bent down to the leg part of the cantilever arm. Insert the thin plate vertically on the edge. The lower and upper grooves of each sheet are used exclusively to receive ventilation grids and the like. The egg-shaped thick-walled portions of the ventilation grid are inserted into the upper grooves of the lower thin plate in the thin-plate longitudinal direction, and the thick-walled portions facing the egg-shaped thick-walled portions respectively engage the lower grooves of the upper thin plate.

The disadvantage of this known structure is the lack of flexibility in use. Only immovable fixing of the individual lamellas is planned and possible. Especially when the blinds are very wide and therefore the lamellas are long, the assembly is cumbersome and in certain situations completely impossible under tight local conditions. This is because both the thin plate and the optional ventilation grid must be inserted longitudinally from the side, that is to say over its entire length.

The aim of the present invention is therefore to produce a blind of the kind mentioned at the outset in which thin sheets can be used with great flexibility.

To this end, according to the invention, the upper groove of each thin plate has a cross-section slightly larger than a semicircle and forms part of a pivot joint for pivotally supporting this thin plate, and so does the lower groove. The cross section is slightly larger than the semicircle.

The blind according to the invention is characterized by a pivot joint.
There is an advantage that the angle of the thin plate with respect to the wall of the building can be adjusted very easily. Thereby, for example, the ventilation port or the lighting port can be adjusted from fully open to fully closed.

At the lower fixed end of each thin plate, a slot extending at right angles to the lower groove is provided, and bolts fixed to the lower groove on both sides of the slot respectively penetrate the slot, and if the adjusting rod surrounds this bolt, A simple adjustment mechanism is provided. The inclination of the thin plate can be uniformly changed by the vertical movement of the adjusting rod.

In another embodiment, a cantilevered arm provided prevents the tilt of the lamina from being adjusted. In that case, the above-mentioned ventilation grid or the like can be used. According to the present invention, even in this case, the thin plate can be used as it is. This represents a great cost benefit for blind manufacturers.

In this embodiment, each lamina is secured to the wall via a cantilevered arm, and the hooked web of the cantilever engages the upper fixed end of the lamina from above to tighten it away from the wall. The free ends of the legs of the cantilevered arm engage this holder on the underside of the thin plate to support it and the hooked web of the cantilevered arm has an outer contour slightly larger than a semicircle. A holder for forming a pivot joint together with a seat for the groove and a set screw in the upper groove, and a holder provided on the lower surface of the thin plate is composed of a web extending in the longitudinal direction of the thin plate and a tightening protrusion, and when mounting the thin plate, This tightening bar engages with a fixed hook at the free end of the leg of the cantilever arm and is held tightly by the hook-shaped web of the cantilever arm only in the inclined position where the thin plate is attached, but is almost horizontal. In the position, the cantilever arm is pulled so that it can be pulled out from the seat. Technical shaped web or sheet upper fixed end for insertion slot formed by the hook-shaped web is formed.

In this way, the mounting of the lamellas is no longer carried out laterally in the longitudinal direction of the lamellas, but at right angles to the wall. In that case, each lamella is inserted in a substantially horizontal position in the seat formed by the hook-shaped web of the cantilevered arm, and then downwards about the axis of rotation of the lamellas of the lamella, i.e. of each lamella. The tightening protrusion provided on the lower surface is rotated until it engages with the fixed hook of the leg portion of the cantilever arm. Since the lamellas can no longer be pulled out of the seat at a right angle to the wall in the thus determined tilt position, pivoting the lamellas down causes a double lock.

If the attachment of a ventilation grid is considered, the first edge of the ventilation grid with a wall thickness that matches the inner contour of the upper groove of the sheet is pressed into this upper groove. When the upper lamellas above this lamella are subsequently assembled, if this upper lamella is turned down into the tightening position, the second edge of the ventilation grid opposite to the first rim will also have an upper lamella. Is pushed into the lower groove.

The elastic tabs on the lower surface of the thin plate are directed toward the lower fixed end of the thin plate body, and the web carrying the elastic tabs is located approximately twice the distance from the upper fixed end to the lower fixed end. By being provided, a spatially suitable arrangement is provided.

The pivot joint provided according to the invention for the upper end of the lamella can also be transferred to the lower end of the lamella while retaining all essential advantages. In that case, the lower end of the thin plate is fixed to the front foundation structure. The closed blind is roughly in the front plane.

Next, the present invention will be described in detail based on the embodiments shown in the drawings. Fig. 1 is a view of a thin plate, Fig. 2 is a plan view of the end of the thin plate with a sleeve and a screw inserted in the groove, Fig. 3 is a schematic diagram of the adjusting method of the thin plate, and Fig. 4 is attached to a cantilever arm. FIG. 5 is a detailed view of a joint of a cantilever arm, FIG. 6 is a view of a single cantilever arm, and FIG. 7 is a deformation of the cantilever arm for tightening the thin plate bearing. A detailed view is shown.

The thin plate shown in FIG. 1 has an oblique thin plate body 1. At the upper fixed end of the thin plate body, opened to the upper surface side of the thin plate body 1,
A groove 2 slightly larger than a semicircle is provided. At the lower fixed end of the thin plate body 1 is a groove 3, which is also open and extends slightly larger than the semicircular shape. Groove 3 is open almost opposite to groove 2. The groove 3 is connected to the drop end 5,
It projects at an obtuse angle with respect to the thin plate body 1.

2 and 3 schematically show that the thin plate shown in FIG. 1 is fixed so that the tilt can be adjusted. By inserting the sleeve 7 into the groove 2 and screwing the groove 8 projecting through the hole of the fixed side plate 6 into this sleeve 7, the upper fixed end of the thin plate is fixed to the fixed fixed side plate 6.
Thus, the upper fixed end of the thin plate is fixed. The sleeve 9 is also inserted into the groove on the lower fixed end, and the bolt 10 is screwed into the groove. The bolt 10 bridges a slot 11 formed in the lower fixed end of the thin plate. The slot 11 extends perpendicular to the longitudinal direction of the sheet. Adjusting rod 12 is bolt 10 in slot 11.
Surround.

By the ascending / descending movement of the adjusting rod 12 shown by the double-headed arrow in FIG. This is possible because the screw 8 or the bolt 10 can rotate in the grooves 2, 3 about the rotary shaft 13 shown in FIG.

As shown in FIG. 2, the arrangement of the sleeve 7 and the screw 8 can be replaced with a self-tapping screw 8 '. This self-tapping screw 8'is screwed into the wall of the groove 2 by itself.

4 to 8 show another fixing method of the thin plate. This other method does not allow adjustment of the sheet tilt, but presents another advantage.

In this case, the thin plate is held by the cantilever arm 14. The cantilever arm 14 has a seat 15 for the circular outer contour of the groove 2. The cantilever arm 14 has a leg portion 17 that is in close contact with a rail 16 of the front foundation structure, and a leg portion 18 extends vertically from the lower end of this leg portion. The free ends of the legs 18 are provided with hooks 19 that make an acute angle and point upwards, and the clamping lugs 20 of the web 4 that point towards the lower fixed end of the thin plate hook.
Overhang behind 19. Therefore, the thin plate is fixed to the cantilever arm 14 by inserting the outer contour of the groove 2 into the seat 15 of the cantilever arm 14 and then attaching the tightening protrusion 20 of the web 4 to the back of the fixing hook 19. Is done by doing. The web 21 of the seat 15 which projects from above on the outer contour of the groove 2 prevents the upper end of the sheet from coming out of the seat 15 in an inclined position determined by the locking between the fixing hook 19 and the web 4. The thin plate can be attached to and detached from the seat 15 only at a substantially horizontal position of the thin plate.

As can be seen in FIG. 4, the ventilation grid 22 is inserted between the groove 3 opened on the rail 16 side of the upper thin plate and the groove 2 opened on the opposite side of the rail 16 of the lower thin plate, By locking the thin plate to the cantilever arm 14 concerned, the ventilation grid 22 is simultaneously fixed together. For this purpose the ventilation grid has a longitudinal web 23 which matches the inner contour of the grooves 2,3. The longitudinal webs 23 may be formed so that they are retained in the grooves 2,3 by some tightening effect.

The cantilever arm can be moved in the rail 16 in the longitudinal direction of the rail 16 by the T-shaped protrusion 24. As shown in FIG. 5, the T-shaped overhang 24 comprises two legs with a free gap therebetween. The overhang 24 is formed of an elastic material, which allows the legs of the overhang 24 to be compressed toward each other so that the overhang 24 can be press fit into the rail 16. The cantilever arm is provided with a filling piece 25 on the upper side, and this filling piece 25 enters into the gap between the two legs of the overhanging portion 24 to tighten the two cantilever arms 14 together. Filling piece
The 25 sequences are particularly apparent in FIG.

FIG. 7 shows that the lower end of the cantilever arm 14 has a web 26 bent downward in an L shape so that the web 26 can be seated even if the thin plate is lifted.
15 shows a modified embodiment which makes it impossible to pull the lamellae out of 15. Therefore, in order to pull out the thin plate, the lower cantilever arm must be separated from the upper cantilever arm.

The cantilevered arm 14 configured in this way is provided with the cantilevered arm 14 on the rail 16
The thin plate can be fixed simply by engaging and sliding it on the plate, and a screw joint is not necessary. Thin plate 14 and ventilation grid 22
Is fixed exclusively by snap fittings and bayonet fittings.
