Description

The invention relates to the field of construction, namely to movable elements of building structures, and are intended to cover openings in fencing structures (fences) with the possibility of periodically opening them by rolling back in a plane parallel to the plane of the fence itself.

Sliding (entrance) gates are a reliable design for controlling access to a fenced area. Usually they are installed in the territories of large warehouses, in enterprises engaged in the production of something, in the garden plots of country houses.

Sliding gates come in the following types:

- suspended sliding gates;

- cantilever sliding gates;

- sliding gates on rails.

Cantilever-type sliding gates are the most common design today, proven and easy to use. Cantilever-type sliding gates are the most complex in design. But these are the gates that are most suitable for the Russian climate. The door leaf is suspended on cantilever rollers using a guide beam, which is located in any part of the door (usually at the bottom) and is fixed to a solid foundation by means of roller trolleys. Such gates do not have beams above the passage and rails below it. The cantilever gate leaf hangs over the passage. Sliding cantilever gates, in turn, are divided into types according to the location of the supporting beam: top, middle, bottom.

The advantages of sliding cantilever gates are:

- lack of contact with the ground rail and restrictions on the height of the vehicle;

- enhanced reliability;

- even in heavy snowfall, the operation of the gate is not disrupted (they are located at a distance of at least 10 cm from the ground);

- can be equipped with automation and security systems.

Sliding gates are divided into single-leaf and double-leaf.

The single-leaf version has a simple design - the gate leaf completely covers the entire opening. The double-leaf design of sliding gates is somewhat more complicated - the leaves converge in the middle (or where it is convenient for the owner), and a separate structure is created for each of them.

Sliding gates are made from profile pipes. The most popular metal section is 60x40x2 mm, which is suitable for most structures and has sufficient strength and does not overload the beam with excess weight.

The size of the gate can be different, it depends on the operational needs for a particular facility, most often there are passages of 4-6 m, sometimes 6-8 m. The size of the passage determines the size of the profiles from which the frame is made and the size of the cantilever system on the basis of which the doors will be made gates, the larger the passage, the longer the console and the more massive the gate, and therefore the load on the roller supports and the structure of the sliding gate frame is higher. Therefore, manufacturers have several types of cantilever systems, which differ in the dimensions of the guide rail and the roller supports for them.

Some patented technical solutions concern cantilever-type sliding gates.

For example, in the technical solution for the Russian utility model patent No. 146285 “Sliding gates” (priority date 06/10/2014, publication date 10/10/2014, Copyright holder Dmitry Ivanovich Shchennikov). This solution describes sliding gates, which include a leaf mounted on a guide made in the form of a hollow beam with a longitudinal slot; the beam is mounted on roller supports, which are mounted on adjusting supports. The gate also has a load-bearing support, a catcher support and is equipped with guide rollers. In this case, the supports are fixed on foundations made using screw piles and channels. The support of the catcher is made of all-metal (from metal racks) and is fixed to the base. The load-bearing support is also made of all-metal (from metal racks) and is fixed on its own base, which includes at least four screw piles. Each base has at least one longitudinal support flange parallel to the plane of the sash. In this case, one longitudinal flange of the base of the load-bearing support and one longitudinal flange of the base of the catcher support lie on the same geometric axis. The bases also have transverse shelves, the axes of which are perpendicular to the plane of the sash, or oriented at an angle to it. The gate leaf is also equipped with a counterweight having a frame structure in the shape of a right triangle mounted on the support leg.

The disadvantage of this solution is the presence of a frame structure in the shape of a right triangle - a counterweight, which is adjacent to the rectangular part of the leaf; this design of sliding gates is not symmetrical, which makes it insufficiently versatile and complicates their installation and manufacture.

As the closest analogue (prototype) of the claimed invention in terms of the totality of essential features, a technical solution was adopted for the Russian utility model patent No. 197556 “Universal sliding gates” (priority date 08/30/2019) a gate is described, including a frame, a post with catchers, a support post, an upper and lower catchers, a guide roller, roller supports and a bracket with rollers and a toothed rack attached to it, wherein the gate is a collapsible structure connected with bolts, and the lower guide frame is made with the possibility of screw fastening the bracket both from its outer and from the inside. Sliding gates can easily be transported to the installation site, assembled without the use of special equipment, and the right-left direction of movement of the gate can be determined by the consumer himself when assembling the gate.

The disadvantages of the prototype include:

- the frame design is symmetrical only with respect to the front and inner parts, but not symmetrical with respect to its beginning and end, since the frame design includes jibs, which makes the design insufficiently universal during installation and use;

- the rectangular part of the frame is a geometrically variable structure and does not provide sufficient rigidity in the vertical direction (its own weight of the structure and the weight of the filling), which does not exclude sagging of the frame;

- in the closed, middle or open position of the gate, the rigidity of the frame in the vertical direction will be different, because the frame is not symmetrical relative to the beginning and end, since the jibs are located only in the rear part of the frame;

- the frame consists of rectangular and triangular parts, while the filling is attached only to the rectangular part of the frame, which requires precise measurements when manufacturing sliding gates and does not exclude the possibility of difficulty during installation.

The purpose of the present invention is to eliminate the above-mentioned disadvantages of the prototype, namely to create a symmetrical design of sliding cantilever gates, the design of which ensures structural rigidity in the vertical direction.

This goal is achieved by the fact that the frame of sliding cantilever gates is made symmetrically with respect to the beginning and end and the frame design includes vertical and inclined braces.

Accordingly, the technical result of the proposed technical solution is as follows.

The proposed invention makes it possible to increase the structural rigidity of sliding cantilever gates in the vertical direction and increase the versatility of the design during installation and use by including vertical and inclined braces in the frame design and making the frame in the form of a symmetrical rectangle.

The technical result is achieved by the fact that the frame of a sliding cantilever gate includes a frame frame 2, a guide rail 1, top 3, middle 4 and bottom 5 veins, between the top 3 and bottom 5 veins there are vertical posts 6, and between the top 3 and middle 4 veins and Between the middle 4 and bottom 5 veins there are inclined braces 7, while the inclined braces and middle veins are made symmetrically with respect to the vertical posts, and the inclined braces are connected in the center of the middle vein.

The claimed technical solution is illustrated by the image of the frame of sliding cantilever gates (Fig. 1), where: 1 - guide rail; 2 - frame frame; 3 - upper vein; 4 - middle veins; 5 - lower vein; 6 - vertical racks; 7 - inclined braces.

To obtain a technical result, the invention can be implemented in the following preferred manner, which does not exclude other embodiments within the scope of the claimed claims.

The frame design of sliding cantilever gates includes a frame frame 2, a guide rail 1, upper 3, middle 4 and lower 5 veins, vertical posts 6 and inclined braces 7.

The frame of frame 2 consists of horizontal and vertical elements made of rectangular profile pipes, which are interconnected and form a rectangular shape.

The frame frame 2 is made symmetrically with respect to the front and inner sides, as well as with respect to its beginning and end, due to which the design of the sliding gate can be either left or right during installation.

A guide rail 1, upper 3, middle 4 and lower 5 veins made of rectangular profile pipes are attached to the frame frame 2. Between the upper 3 and lower 5 veins, vertical posts 6 are placed at the same distance from each other.

Between the vertical posts 6 and the vertical elements of the frame 2 there are middle veins 4 at an equal distance between the top 3 and bottom 5 veins.

Inclined braces 7 are located between the lower 5 and middle 4 veins and between the top 3 and middle 4 veins. The inclined braces 7 are connected to each other in the center of the middle vein 4.

The upper 3, middle 4 and lower 5 veins are necessary for fastening the filling of the frame of sliding cantilever gates, for example, with corrugated sheets, picket fences, wood, etc.

Vertical posts 6 and inclined braces 7 are made of rectangular pipes. Vertical posts 6 and inclined braces 7 are made in the design of the frame of sliding cantilever gates in such a way that they form a strong system of geometrically unchangeable shape, which makes it possible to eliminate sagging of the frame frame 2 even when covering openings more than 6 m long, and also to use heavy materials as filling for sliding gates. cantilever gates, for example, wood.

Vertical posts 6 and inclined braces 7 are designed to increase rigidity in the vertical direction of the frame frame 2.

The symmetrical arrangement of the vertical posts 6 and inclined braces 7 in the frame frame 2 makes it possible to ensure the rigidity of the frame frame 2 in any position of the gate - closed, middle or open.

The vertical posts 6 and inclined braces 7 are arranged in such a way that when connected to each other they form triangles. When a structure consists of rod elements connected to each other at nodes in this way, then it is geometrically unchangeable and all rod elements of this structure work in compression or tension, and not in bending. Rod elements work much more effectively in compression and tension than in bending. But their length and cross-sectional area must be such that the rod element does not begin to bend under load (lose stability). In order for all these conditions to be met, such an arrangement of inclined braces and vertical posts has been proposed.

The filling can be used to cover the entire side of frame 2 from start to finish, which allows it not to be rigidly tied to the opening in the fence. In addition, you can sew up the inside of the frame at any time during the operation of the gate with any filling, for example, corrugated sheets, picket fences, etc.

Thus, the proposed design of the frame of sliding cantilever gates makes it possible to increase the structural rigidity of sliding cantilever gates in the vertical direction and increase the versatility of the design during installation and use.

The applicant currently carries out its own industrial use of sliding cantilever gates.
