Description

The invention relates to the field of fixed or movable elements for closing openings in buildings, vehicles or the like. devices [E06B 9/11].

The prior art is known ROLLER CURTAIN WITH ADJUSTABLE DISTRIBUTION PLATES [PT 3184726 (T), publ. 02/01/2019], containing a plurality of parallel bars, limited relative to each other, so that they can be wound around the roller, to which the first of the said bars is attached, characterized in that part of the said bars has a distance from each other, and some of the said bars do not can be located relative to each other, and said one-piece strips are the first, starting from the said roller, and that said removable strips are limited relative to each other by means of U-shaped hooks sliding inside the grooves provided in the profile. The disadvantage of this analog is its low reliability, due to the connection of the strips with U-shaped hooks sliding inside the grooves. In addition, such a connection does not provide the necessary mobility and flexibility for winding the strips around the roller.

Also known from the prior art ROLLER SHUTTER [RU 190319 C1, publ. 06/26/2019], including a shaft with a drive, lamellas interconnected by connecting elements into a web, characterized in that the shaft is made in the form of a regular octagonal prism, on the side faces of which transition elements are fixed, each of which is made with a hole in the form of a reciprocal correct an octagon for a regular octagon of the shaft base, and on the outside, each transition element is made with four arcuate corners, three of which are equidistant from the center of its inner hole in the form of a regular octagon, and the last arcuate corner is made further from the center of its inner hole in the form of a regular octagon, at the same time, the ends of the flexible traction elements connected to the connecting element of the first lamella are connected to the shaft, and the first lamella and the second lamella are equal in width to each other, and then each subsequent two lamellas are made equal to each other in width, but larger than the width of the previous two lamellas,and fixed in such a way that in a twisted position on the shaft, all connecting elements, except for the first four, lie on top of each other, and the first four connecting elements lie on the arcuate corners of each transition element, while the drive with the shaft is configured to unwind the web from the roll position to the position of the canvas and vice versa, twisting the canvas into a roll.

The disadvantage is the connection of the first lamella to the transition elements using flexible traction elements, which significantly reduces the service life of such roller shutters and excludes the possibility of using metal lamellas due to their significant weight compared to plastic ones, as well as making roller shutters for large openings, which in As a result, it leads to stretching of the traction elements and displacement of their position relative to each other in the position wound on the shaft.

The closest in technical essence are roller shutters [RU 190274 U1, publ. 06/25/2019], including a shaft with a drive, lamellas interconnected by connecting elements into a web, characterized in that the shaft is made in the form of a regular octagonal prism, on one side of which the first lamella of the web is rigidly fixed by means of fasteners, while to the first the lamellas are successively attached two lamellas equal to each other of a larger size in width by means of a connecting element, and then each subsequent two lamellas are made equal in width to each other, but larger in width than the previous two lamellas, so that in the twisted position on the shaft all the connecting elements , except for the first four, lie on each other, and the first four lamellas of the web in a twisted position rest on each second face of the shaft, while the driven shaft is configured to unwind the web from the position of the roll to the position of the web and vice versa, twisting the web into a roll.

The main technical problem of the prototype is the lack of a stop for the transition elements of the first row of lamellas on the shaft, and due to the fact that the first four lamellas of the web in a twisted position rest on every second face of the shaft, the said lamellas are subject to deformation, which, as a result, adversely affects their service life and lamella reliability. In addition, roller shutter slats are difficult to manufacture due to the way they are fixed on the transition elements using self-tapping screws screwed directly into the groove of the transition element into which the lamella is inserted. And to ensure the mobility of the lamella in the transition element, it is necessary to make additional grooves in the lamella.

The objective of the invention is to eliminate the disadvantages of the prototype.

Implementation of the invention.

Roller shutters contain a shaft 1 (see Fig. 1), made in the form of a regular polygon in cross section. In one embodiment, the implementation of the shaft 1 in cross section is made in the form of a regular octagonal prism.

At least, at the ends of the shaft 1, transition elements 4 are mounted, in the center of which there are holes corresponding in shape and size to the shaft 1, taking into account the tolerance with the possibility of symmetrical mounting relative to the axes of symmetry of the mentioned transition elements 4 on the shaft 1.

The transition element 4 (see Fig. 2) is made with the possibility of changing the width of the slats 2 depending on the opening closed with the help of roller shutters.

On the inner walls of the transition element interacting with the shaft, protrusions (not shown in the figures) transverse to the mentioned walls are made with the possibility of ensuring a tight fit of the transition element 4 on the shaft 1.

The transition element 4 is made in the form of a regular polyhedral prism containing an even number of main faces, each second face of which is made along the width of the smaller faces adjacent to it with the possibility of placing a connecting element 3 on it, and the remaining faces are made with the possibility of placing lamellas 2 along them, with in this case, the first face of the transition element 4 for placing the first connecting element 3 with the first lamella 2 on it is made protruding relative to the face along which the first lamella 2 is placed. the last lamella 2 of the first row, forming a recess 5 between the said faces. In the said face, a hole is made for mounting the first connecting element 3 to it.

The second and third faces of the transition element 4 to accommodate the connecting elements 3 are made in the form of protruding rectangular areas.

The fourth face of the transition element 4 for accommodating the second connecting element 3 is made adjacent to the adjacent faces for accommodating the slats 2 without forming any protrusions or recesses.

This design of the edges and their mutual placement ensures the exact location of the connecting elements 3 on top of each other when winding the web on the transition elements 4 of the shaft 1.

To reduce the consumption of materials in places of thickening of the transition element 4, under each second face of the transition element 4, through transverse holes are made.

A web is wound on the transition elements 4, made up of rectangular slats 2, made along a length not exceeding the length of the shaft 1. The slats 2 are interconnected by connecting elements 3 (see Fig. 3), made in a rectangular shape, from the side faces of which symmetrically and at the same time C-shaped hooks 8 are made with the mentioned elements 3. The mentioned hooks 8, being a continuation of the upper and lower longitudinal faces of the connecting elements 3, form hooks from below, and from above, clamps with the possibility of interengaging the said hooks with the grooves of the lamellas 7 (see Fig. 4), made along the longitudinal sides of the lamellas 2 and holding the lamellas 2 inside the connecting elements 3 by the clamps. transition element 4. Angle α, for octagonal transition element 4 predominantly equal to 45 degrees. The surfaces of the clamps and hooks facing each other are made parallel, with the possibility of forming support surfaces for the lamella 2 in its folded state.

The outer surface of the latch is made at an angle of 90+α degrees with the possibility of forming a supporting surface for the lamella 2 of the next row of lamellas 2 when laying them on the transition elements 4 (see Fig. 5).

On the side, in the center of the connecting element 3, at least one hole of the plug 6 is made with the possibility of mounting the rod of the plug 9 into it (see Fig. 6), while the rod is made with a variable section (corrugated or spring) with a thickness in the widest part exceeding the dimensions of the opening of the plug 6 in the connecting element 3 with the possibility of entering the said opening 6 of the connecting element 3 into tension, and the cap is made with the possibility of entering the lamellas 2 mounted on both ends of the transition element 3 to fix them and prevent displacement of the transition elements 3 in the grooves slats 7. The plug 9 thus ensures a reliable connection of the slats 2 and the reliability of the roller shutters as a whole.

In one embodiment, the plug 9 may contain bushings (not shown in the figures) located on both sides of the rod symmetrically along the plug 9 with the possibility of interaction with the C-shaped hooks of the connecting elements 3 and additional fixation of the lamella 2 in the connecting element. To do this, the length of the bushings must be less than the width of the connecting element 3, and in the ends of the lamella 2 at the corners, symmetrical cutouts must be made to accommodate the said bushings.

The first lamella 2 is mounted with the help of a connecting element 3 against the stop wall 5 of the transition element 3, while the said connecting element 3 is mounted to the transition element 4 by a detachable screw or bolt connection, for example, a self-tapping screw with a countersunk head or a screw, while in one of embodiments for the detachable connection of the connecting element 3 with the transition element 2 in the said connecting element 3, a through hole with a variable cross section is made with the possibility of placing a hardware cap inside the connecting element 3.

To the last slat 2, an end plate 10 is mounted (see Fig. 7), made along the length of the slat 2, while the installation of the said plate 10 to the slat 2 is made using hooks 8, as with the connecting elements 3. A damper is mounted to the end plate 10 11 with the possibility of elastic interaction with the floor surface of the opening. The end plate 10 is made with the possibility of weighting the web. In one embodiment, through-holes are made across the end plate 10 with the possibility of reducing material consumption. From the ends of the end plate 10, a plug of the end plate 12 is mounted to the holes (see Fig. 8), the cap of which is made with the possibility of overlapping the last lamella 2 to fix the end plate 10 relative to the last lamella 2.

Roller shutters are used in the following way.

Before use, roller shutters are placed in a closed opening. The shaft drive 1 is turned on, which drives the shaft 1 and, depending on the initial position of the web, lowers or raises the web of lamellas 2. When the web is raised, the first three lamellas 2 rest with their connecting elements 3 on the edges of the transition elements 4. The subsequent rows of lamellas 2 rely on their connecting elements 3 on the connecting elements 3 of the previous row of slats 2, while the width of the slats 2 increases with each of the subsequent turns. To turn off the shaft drive 1 in the extreme positions, the roller shutters are equipped with limit switches (not shown in the figures), with the possibility of excluding the winding of the web in the opposite direction. The C-shaped execution of the hooks 8 of the connecting elements 3, taking into account the tolerance for the angle of deviation of the lamella 2, provides a reliable and at the same time movable connection of the lamellas 2 to each other in the canvas within the limits of the design of the clamps and hooks of the said hooks 8 angles, while due to the angle of inclination of the outer surface of the latch at an angle of 90+α degrees, the slats 2 of subsequent rows rest on the said surfaces of the clamps, which ensures tight winding of the slats on the transition elements 4 of the shaft 1, which increases the accuracy of fitting the slats 2 and the connecting elements 3 to each other and thereby increases the reliability of the design of the roller shutters as a whole.

The fixation of the connecting elements 3 between the slats 2 connected with their help by plugs 9 ensures the maintainability of the web and the roller shutters as a whole due to the fact that to replace the slats 2 it is enough to remove the plugs 9 of the replaced slat 2, thereby releasing the connecting elements 3 and removing the mentioned connecting elements 3 from slats 2. Installation of a new slat 2 is carried out in the reverse order.

EFFECT: increasing the reliability of roller shutters is achieved due to the special design of the transition element 4, which, using the recess 5, made in the face, makes the second face of the transition element 4 to accommodate the second connecting element 3 adjacent to the adjacent faces, without the formation of any protrusions or recesses. , and the third and fourth faces of the transition element 4 for placing the connecting elements 3 in the form of protruding rectangular areas allows you to accurately position the connecting elements 3 on top of each other when winding the web on the transition elements 4 of the shaft 1, which eliminates their displacement, uneven winding of the web and improves reliability roller shutters. The reliability of the roller shutters is also influenced by the special design of the connecting elements 3, which is made in such a way that it ensures the reliable retention of the slats 2 in the conformable hooks 8 of the mentioned elements 3, the necessary deviation of the slats 2 during their winding/unwinding and the emphasis of the slats of the adjacent row on the walls of the clamps. And the very principle of connecting the slats 2 with the help of the mentioned connecting elements ensures the maintainability of the roller shutters.
