Overhead door

The invention relates to an overhead door, in particular for locking garages and various Dandruff, its movement during opening towards the outside of the shed to take place, taking up the least amount of space within the same, not in the raised position protrudes outwards and is practically parallel to the ceiling, these results being achieved without the use of guide rails. will hold.

According to the invention, on each side of the gate there is a paddock that carries two axes, which pivot points form for two arms, which are hinged at their other end to two axes, which by means of an angle attached to the lower part of the gate, while a small arm attached to the axis of one of the arms is attached to its free one End of an articulated pinger for attaching one end

an elastic member, the other end of which is attached to the j ^etp * * part of one of the posts bordering the gate, in such a way that these two joint arrangements ensure good stability of the gate when it is parallel to the ceiling of the room to be closed, the gate is locked when it is perpendicular, that is, when it closes the space, since the design is made so that the two elastic members are under tension and the joint arrangement passes a dead center before the closed position of the gate.

According to a further characteristic of the invention the resilient member of each hinge assembly is attached to the lower part of the posts bordering the gate, to the small swivel arm carries a collar, which serves as a stop for a downward lever, the free end of which is on is attached to one end of the elastic member.

The invention is explained below by way of example with reference to the drawing.

arm 7 hinged at one end is on at its other end an axis 8 fixedly connected to a bracket 9 attached to the lower rear bearing of the gate 1. The other side of the gate 2 is of course designed in the same way, i.e. an angle 9 is also attached at the same height. Further is a second arm 10 with one end on the axis 6 of the flange 4 and with its other end on one on the rear lower one Part of the angle 9 attached axis 11 is articulated. Finally, one end 12a forms a small one that can pivot on the axis 5 Arms 12 a pivot point for a provided with a collar 13a s.tarres link 13. The free end 131) of the link 13 is used as an attachment point for one end of an elastic member 14 »the other end of which is at one on the rear part of the gate edging post "clevis 15. When the gate is closed as shown in Figure 3, i. when it is perpendicular, the various parts assume the positions shown.

When the shed is to be opened, will

the gate tilted in the direction of the arrow F ^ (Fig. 3). It then describes the various dash-dotted lines in Pig. 1, the curve Cj the movement of the axis 11, the curve Cg the movement of the axis 8, and the curve CU the movement of the upper end of the gate 1 between the vertical position and the horizontal position to the roof * T of the shed indicates parallel position. During this movement, the lower end of the arm 7 follows the curve Cg »whereby, due to the presence of Her axis 5, it entrains the small arm 12 on which the rigid member 13 is attached, on the collar 13a of which the small arm 12 is supported. The spring 14 contracts, whereby the movement of the gate 1 is supported. Likewise, the lower end of the arm 10 follows the curve 0 ^. Like in Pig. 1, "the gate is opened outside the shed *" so that it is blocked as little as possible during this movement. Furthermore, due to the horizontal position of the gate 1, which is cantilevered with respect to the axes 5-6 (see FIG. 1), the fact that it does not by itself in the direction of the arrow J? ₂ O ^ -B ·· * "1} toggle *.,

movement in the opposite sense, i.e. in the sense of the arrow Pg (Pig. 1), during this movement, however, the springs 14 are tensioned, which facilitates the actuation, since the downward movement of the gate is braked in this way. When the gate is closed, and as a result of the attachment of the springs 14 to the end of the small arms 12, the movement exceeds a dead center, creating the correct one Locking of the gate is achieved, which can only be opened when a fairly strong pressure is exerted on it thereby preventing its unilateral opening.

In Pig · 4 and 5 , the gate 20 again has two brackets 9 attached to both sides of the opening 3 on the post, to which the arms 7 and 10 are articulated by axes 8 and 11, which also to those on the paddles 4 fixed axles 5, 6 are articulated. The axle 5 carries a small arm 21 provided with a collar 21a. The end 211> of the small arm 21 carries an axle 22 on which a lever 23 is pivotable, the end 23a of which is attached to an elastic member 24 which is secured by fork heads 25 is connected to the post bordering the opening 3 of the shed. The operation of the Torah is the same as that described above, but the placement of the pedestal on the lower part of the gate is sometimes more interesting to avoid obstruction of the shed.
