Description

The useful model refers to the field of construction, as well as to the furniture industry, namely for equipping the interiors of office and residential premises, in particular, for overhead sliding door systems for wall openings, as well as for wardrobes.

The closest in terms of technical substance to the claimed useful model is the device for moving the leaf of the top-suspended system of sliding doors of the company ZEMVOI I | see. "assembly instructions", presented on the website of the mlmliu.zemgoi!.ri page 22, 23), which includes the upper guide profile and two rollers, each of which is equipped with a body on which two axes are installed with the possibility of rotation relative to it, on each of of which two wheels are installed, while the mounting finger is fixed in the body, the free part of which is made with an external thread, and the upper guide profile has a U-shaped section with side plates bent inward, which form the corresponding surfaces for moving the rollers and are made in such a way that it is adapted for hanging a door leaf on it with the help of roller mounting fingers.

One of the disadvantages of this device is low reliability.

The mentioned shortcoming in the closest analysis is due to the fact that the mounting fingers of the rollers are not installed in the center of the housings, but with a shift, which leads to an uneven load on the wheels of the rollers and, as a consequence, to the rapid breakdown of the wheels, because in the upper suspension system of sliding doors, the rollers are with the help of mounting fingers, they are attached to the sash, the weight of which is distributed on the wheels of the rollers, which rest on the corresponding surfaces for moving the rollers of the upper guide profile.

Because of the mentioned shortcoming, the company ZEMVOI HER. introduced restrictions on the weight of one leaf, namely the maximum weight of one leaf up to 5 kg | see "assembly instructions" of the EARTH HER company. page 221.

Another important disadvantage of the closest analogue is the lack of the possibility of using it to move C-shaped flaps.

The modern design of the interior of the premises suggests the overlapping of corner spaces, which is possible during use

C-shaped flaps, and therefore a curved C-shaped upper guide profile.

This drawback is due to the shape of the working surfaces of the roller wheels, which have an inwardly concave shape, as well as the mushroom-shaped surface for moving the rollers. Such a design, when using a curved C-shaped upper guide profile, will lead to jamming of the rollers even with a relatively small movement of them.

The useful model is based on the task of improving the well-known device for moving the sash of the top-suspended system of sliding doors by changing the fastening of the mounting pin in the body of each roller, as well as a new design of the working surfaces of the wheels and the side plates bent inward of the upper guide profile, which will increase the reliability of the device, as well as to expand the operational characteristics of the device due to the possibility of using the device to move C-shaped sashes to cover the corner spaces of the premises.

The task is achieved due to the fact that the mounting finger of each roller is fixed in the center of the housing and located along the vertical axis of symmetry, while the working surfaces of the wheels are curved outward and have

C-shaped, and the inwardly bent side plates of the upper guide profile are made in the form of C-shaped profiles in such a way that the surfaces for moving the rollers have a shape close to the shape of the wheels of the rollers, and the upper guide profile is curved in a C-shape.

Fixing the mounting finger of each roller in the center of the body with the one located along the vertical axis of symmetry allows you to evenly distribute the weight of the door leaf on the roller wheels, thereby increasing the reliability of the device due to the long-term operation of the rollers without the wheels breaking, and also to use door leaves with regard to heavy weight, where mirror, glass will be used as facade filling.

Making the working surfaces of the wheels curved outwards C-shaped, as well as making the side plates of the upper guide profile bent inward in the form of C-shaped profiles in such a way that the surfaces for moving the rollers have a shape close to the shape of the wheels of the rollers, and making the upper guide profile curved C - similar shape allows you to expand the operational characteristics of the device due to the possibility of overlapping the corner spaces of the premises. The curvilinear door leaf easily moves along the curved upper guide profile with the help of rollers in the complete absence of jamming of the rollers.

A useful model is explained by drawings:

Fig. 1 - a general view of the device for moving the sash of the upper suspension system of sliding doors;

Fig. 2 - a front view of the device for moving the sash of the upper suspension system of sliding doors;

Fig. 3 - side view of the roller;

Fig. 4 - roller top view.

The device for moving the sash of the top-suspended sliding door system includes: upper guide profile 1, rollers 2, C (Fig. 1, 2); each roller contains: body 4, axles 5, 6, wheels 7, 8 and 9, 10, mounting finger 11 with threaded part 12 (Fig. 3, 4).

Two axes 5, 6 are installed on each roller housing with the possibility of rotation relative to it, each of which has two wheels 7, 819,10.

The working surfaces of the wheels 7, 8 and 9, 10 are curved outwards and have a C-shaped shape.

The mounting finger 11 of each roller is fixed in the center of the housing 4 and is located along the vertical axis of symmetry.

The upper guide profile 1 has a U-shaped section with side plates bent inward, which are made in the form of C-shaped profiles 13, 14 (Fig. 2), so that the surfaces for moving the rollers have a shape close to the shape of the wheels of the rollers.

The device for moving the sash of the overhead system of sliding doors is mounted as follows:

The upper guide profile 1 is rigidly fixed with the help of mounting screws to the corresponding support surfaces, this is the ceiling of the room or the upper horizontal surface of the wardrobes, after which rollers 2, 3 are installed in the upper guide profile 1, which with the help of wheels 7, 8 and 9, 10 kinematically interact with the corresponding surfaces to move the rollers, then with the help of the threaded parts 12 of the assembly fingers 11 fasten the sash (not shown in Fig.) to the rollers 2, 3.

When a horizontally directed force is applied to the leaf (not shown in the figure), the indicated leaf is moved with the help of rollers 2, C relative to the upper guide profile 1 in the desired direction.

Due to the fact that the mounting finger 11 of each roller is fixed in the center of the body 4 and is located along the vertical axis of symmetry, the weight of the door leaf is evenly distributed on the wheels 7, 8 and 9, 10 of each roller, which even with a significant weight of the leaf (more than 50 kg) allows long-term to operate the rollers without their replacement or repair, which ultimately allows to increase the reliability of the device.

Making the working surfaces 7, 8 and 9, 10 of each roller curved outwards in a C-shape, as well as making the side plates of the upper guide profile 1 bent inwards in such a way that the surfaces for moving the rollers have a shape close to the shape of the wheels of the rollers and making the upper guide profile curved C-shaped allows you to expand the operational characteristics of the device due to the possibility, if necessary, to overlap the corner spaces of the premises, in this case, the curved door leaf (not shown in Fig.) with the help of rollers 2, C is easily moved along the curved upper guide profile 1 in the complete absence jamming of rollers.

The proposed device for moving the sash of the top-suspended system of sliding doors can be manufactured at machine-building plants using the equipment used on them. schi y A Ky te no rik V. Where did I y r (uh y ate eh soy y zho ia U se dn sey -y
