GATE RETRACTABLE

The technical solution proposed for protection by the RF patent for a utility model relates to devices designed to close openings of various types of structures, for example, to lock car garages.

The prior art devices of a similar purpose are well known, for example:

- a device for opening a sliding gate, containing it, its drive, a cable block system that interacts with the emergency handle, a smooth-running mechanism in the form of a counterweight, a hydraulic speed controller and an additional cable block system (see USSR author's certificate No. 779566, class E 05F 15/00 , 1980) (1);

- a device for opening sliding doors containing a drive, a cable block system connected with a door, and a drum (see USSR author's certificate N 452660, class E 05F 15/06, 1974) (2);

- a device for opening sliding doors containing a drive, a power hydraulic cylinder, a cable block system connected with a door, and a drum (see USSR author's certificate N 559018, class E 05F 15/06, 1977) (3).

The disadvantages of these devices are low reliability and high material consumption due to the presence of a gearbox that reduces the speed of the drive in order to create the necessary effort to move the wings

gate With a given speed, complexity of devices and the presence of brake blocks.

Also known from the prior art is a device for moving sliding doors containing a drive, a number of support and brake blocks that are bent around by an endless cable (see USSR author's certificate N 1428886, class E 05F 15/06, 1988) (4).

The closest in technical essence analogue of the claimed technical solution (prototype) are sliding gates containing a base with guides, a reversible drive and a sliding frame. The retractable door frame is made with guides and leans on the base guides through the rollers. The reversing drive is mounted on the base, on the guide of which the roller is mounted for movement, connected to the drive and consisting of two halves connected through one or more bearings to the axis. Two different-sized sprockets can be rigidly mounted on the axis of the roller associated with the drive. On the guide, on which the roller is mounted to move, the bypass blocks can be located, the axis of one of which is connected with the drive. Two equal-sized sprockets can be rigidly fixed on the axes of the bypass blocks. The drive chain can be stored through the sprocket blocks of the bypass blocks and mesh with the upper parts of the roller axis and the lower parts of the chain cross. The upper roller can be offset relative to the lower roller towards the center of gravity of the sliding frame, and in the open position of the gate, the lower roller can be moved away from the center of gravity of the sliding frame in the direction of the upper roller. The rollers and all the guides can be made toothed (see patent RU No. 2049898 C1, E 06 VZ / 46, 12/10/1995) (5).

- large metal consumption,

- difficulty in manufacturing,

bulkiness

- the complexity of the operation of the gate and their maintenance,

- restriction in the choice of a covering material of a gate.

The objective of the utility model is to eliminate the above disadvantages by creating a new design of sliding gates.

The technical result is the creation of an original, simplified design of the gate, thanks to which the gate is simpler and cheaper to manufacture, operate, repair. Acquired such valuable quality as the ability to repeatedly change the door trim material without changing their overall design.

This problem is achieved in that the gate is retractable, containing a retractable frame, rolling units, consisting of axles, bearings and rollers, according to the claimed utility model, comprise a non-drying frame consisting of at least two load-bearing posts, an upper bridge and, according to at least one support, while the axes of the rolling units are mounted on the carrier frame with the possibility of entry into their rollers retractable frame, made with the possibility of movement in the rollers relative to the carrier frame.

In addition, the gate can be additionally equipped with a drive to move the sliding frame.

In addition, the sliding frame of the gate can be made of a profile pipe, the supporting posts are made of rectangular pipes, the upper bridge is made of a channel, and the supports are made of a corner.

In addition, the sliding frame of the gate can be sheathed with a wooden fence, or siding, or a perforated sheet of metal.

Below is a description of the graphic materials in no way limiting all possible options for implementing the claimed technical solution.

In FIG. 1 schematically shows a gate, an inside view, a side view and a top view (open-closed).

In FIG. 2 schematically shows a rolling unit.

A drive (not shown) for moving the sliding frame (1) can be installed in various places of the gate, for example, on a supporting frame (3).

The retractable frame (1) of the gate can be made of a profile pipe, the supporting posts (4) of rectangular pipes, the upper bridge (6) of the channel, and the supports (5) of the corner.

The roll-back frame (1) of the gate can be communicated with a wooden picket, or siding, or a perforated sheet of metal.

The following is one example, in no way limiting all possible options for implementing the claimed technical solution.

The retractable frame is made of a profile rectangular pipe, the thickness of which is selected depending on the width of the doorway and the weight of their casing. Blanks for the perimeter of the frame are cut to a predetermined size at an angle of 45 degrees, to ensure the greatest strength. Then they are welded at right angles to each other and filled with stiffeners to ensure the elimination of bending deformation (sagging) of the sliding frame. Since in any of the extreme positions of the sliding frame with respect to the carrier, a large bending moment occurs, which only increases in the presence of casing, the number of jumpers (stiffeners) is individually selected for each particular structure.

In the manufacture of a sliding frame, it is important to maintain the size of its height with an accuracy of 0.2 mm. This is dictated by compliance with the tolerance for thermal gaps, as the design should work in a wide temperature range taking into account atmospheric precipitation during long-term and year-round operation. After manufacturing the sliding frame, a circle is welded on one and the other sides to the outer long sides, which contacts the rollers of the supporting frame.

In this case, preference is given to calibrated material. The diameter of the circle should be equal to the diameter of the metal sample in the roller. To improve the operational and aesthetic qualities of the door, all visible welds are cleaned.

Supporting racks, the upper bridge and supports are welded in a right angle. The dimensions of the parts are dictated by each specific case, i.e. depend on the width of the opening and the weight of the door trim.

The rolling unit is formed from an axis, which is welded to the supporting frame, a standard bearing and, for example, a shaped roller. To facilitate the manufacture of the entire structure and ensure the greatest accuracy in the interaction of the bearing and sliding frame, the axes of the rolling units are welded last in place, i.e. The sliding frame must enter the rollers on either side of the supporting frame. This provides convenience during subsequent maintenance (repair) of the entire structure, i.e. replacement of bearings, change or repair of door trim, installation of automatic drive if desired.

When installing the gate, the support racks can be concreted for a more precise fixation. After installing the sliding frame on a supporting frame with the ability to move relative to the latter, the main structural elements of the gate can be considered assembled. Depending on the installation conditions, the sliding frame can be communicated with a wooden fence, or siding, or a perforated sheet of metal. For ease of use, a handle can be mounted on the sliding frame.

As you can see, the design has one degree of freedom - the movement of the sliding frame in relation to the supporting frame. At the same time, there is an unlimited opportunity in the manufacture of door gates, which is important for the aesthetic perception of the entire structure. Also possible

the use of art forging elements, coating with various types of siding, the use of traditional panels, etc.

The design has a number of advantages over analogues not only in the possibility of easy access for maintenance, but also an advantage in winter operation. So, for example, in case of heavy snowfall, having installed a scraper on the supporting frame that will touch the upper guide circle, self-cleaning (a kind of protection against jamming) will occur when opening the gate, which is extremely important when using drives for automatic control of the gate.

As a result of the development of such a design of sliding gates, it was possible to significantly simplify the construction of the gates, which led to a decrease in their metal consumption and bulkyness. The practice of installing and using gates has confirmed that their operation and maintenance have become simpler and cheaper. An important addition was the almost absence of restrictions on the choice of sociable material for the sliding frame, which, of course, positively affects the aesthetic perception of the gate and increases their compliance with consumer expectations.
