Description

one

The image refers to co-operation and can & be used in the construction of gateways for sluice transport passages of buildings and structures.

Known sliding vorog cantilever rraia, in which the canvas with a horizontal direction is moved with the help of rollers mounted on a fixed frame {ij,

The disadvantage of these gates is that when they open, the web occupies a near-aperture space equal in size to the width of the opening plus the width of the supporting frame. This leads to the fact that a significant area near the opening can hardly be used, and the need to move the specified web in the circum-space apertures reduces the integrity of the artwork design of the transport passage.

The closest to the invention to the technical essence are the sliding gates, including two curved blades with a cantilever mounted horizontal direction, driving rollers, a fixed frame H drive 2,

A disadvantage of the known technical solution is the presence of an arch with a drive mounted on it, which limits the height of the gate and complicates their operation, as well as leads to the irrational use of the circum-aperture space.

The aim of the invention is to reduce the perimetral space.

This goal is achieved by the fact that in sliding gates having two curved blades with a cantilever-mounted horizontal guide, leading and non-leading rollers, a fixed frame and a drive, the blades of the curtain are bent with a radius equal to the width of the aperture with a center located on the axis of symmetry.

Claims (2)

Sliding gates include blades 1 with a horizontal rail 2 cantilever mounted on them in the middle part, skipped between 3 rollers fixed on a base frame, the lower one of which is leading 4 connected to a.1 running shaft of a mechanical drive, and the upper one. non-leading 5s are located on either side of the lead, In one vertical flatness, the non-leading rollers on the frame have rolls 6 with vertical axes reproducing the horizontal guideway blades. At the same time, the door curtains, in the closed position, are adjacent to the fencing of the opening 7. The door curtains are curved in a horizontal plane around a circle with a radius equal to the width of the door opening with a center that is located on the axis of symmetry of the opening of the door. carriers, and the canvases can be made of profiled sheet material. The locking passage consists of two movable gates and a fence 7, Since the bending radius of the webs is equal to the width of the aperture and the center of the radius is located on the CHMMSTW axis of the aperture, while the arc of the canvases do not have an aperture angle of C ° 6O. cloths, the location of the cloth when you open the gate along the fence; symmetry. " gate from the outside of the gateway. The use of the gate will increase the useful area of the premises by reducing the near-propole space. Claims for sliding gates, including two curved blades with a cantilever-mounted horizontal direction, leading and non-driven rollers, a fixed frame and a drive, characterized in that, in order to reduce the near-gap space, the curtain gates are curved with a radius equal to the width of the opening with the center located on the axis symmetry.
