Description

There are already known devices for opening the garage door with the weight of a passing car using pedal platforms that are lowered under the action of a car and affecting the gate locking device, as well as are known for their inclined hanging. door or door leaves to achieve self-opening or self-closing of these doors by a component of its own weight. In the proposed device, in order to achieve an uninterrupted and uniform automatic opening of the garage door, locking levers are used, connected by a cable pulled by rollers, the axes of which are tightly embedded in the door. When the lever connected to the pedal is rotated, the lower locking lever rises and lowers the upper locking lever, after which the freed gate, obliquely visited on the hinges, is opened under its own weight.

In FIG. Figure 1 shows an exterior view of a gate equipped with the proposed automatic opening device; FIG. 2-view of the gate from the garage; FIG. 3-vertical

incision; FIG. 4-horizontal section (top view).

The proposed device consists of two symmetrical iron bar levers, two soft cables, and two rollers. Each of the levers (Fig. 3) at one end has a thickening with a beveled locking part. In the thicker lower arm there is a hole into which the end of the lever 3 of the manual locking device enters. At the other ends of the levers, two pads are screwed in each to secure the cables. Around the pads in the levers there are elongated slits /, (Fig. 2), one in each; the slits are designed to pass through the axes of the rollers. Cables are fixed in the linings in this way: one end of the cable is fixed on one lever, the second cable is similarly located. The rollers are secured tightly in the door frame by screwing them by means of two plates. The levers are fitted with their slots on the e-axis of the rollers and secured with guide brackets. Rollers are put on the axles above the levers and fastening nuts are screwed on.

Under the influence of the weight of a passing car or pedal carriage (s) (figs. 3, 4), it lowers through the lever and raises the lower arm upwards, and its pad will pull the cable behind it, bending the lower roller, is not the second end upper arm d down, thanks to which constipation; opens up. When lowering the lower arm, its lining will pull the cable that skirts the upper roller, the second end does not sweat the upper arm up, and the gate closes.

Gate loops with stands and ball bearings. A and (Fig. I) are installed in the plane of the opening along the plumb line, and in the plane of the wall cut the upper stand protrudes against the lower one. The latches b serve to keep the door leaves closed; when the gate is locked and the door is locked to the shoe, the lugs are released in the sockets and their weight is lowered down.

Spring strips in (f. 4) snap into place when you open the gate with your own

ends in the brackets g and stop the door leaf from their vibrations in different directions.

The subject matter of the invention.

Claims (3)
