Description

Swing single-wing door

The invention relates to devices for opening and closing pivoting doors and doors and can find application mainly in the construction of the casement doors of cabinets of vehicles, as well as the casement of garages and other similar structures.

Closest to the invention is the design of the swing-leaf of a garage door, consisting of a leaf installed in the frame, connected to each of its sides by a lever and a spring and equipped with a pair of additional levers and two pairs of rods mounted on the frame, each of which is additional the levers are connected by one of the rods to the first of the levers, and the free end by means of the second rod is connected to the sash, while the connection nodes of all elements are hinged, and each of the springs is fixed to ami on both levers (patent of the Russian Federation N 2058470 from 01/09/92. MKI E 05 F 1/08).

The disadvantages of the known device are: the use of a large number of parts, the complexity of the design and, therefore, a decrease in its reliability and durability.

The basis of the invention is the task of simplifying the design, increasing its reliability and durability.

To solve this problem, in a lift-and-rotate single-leaf door containing a casement mounted in the frame, connected to the frame by each side by means of a lever and an additional lever, while the connection nodes of all elements are hinged, the lever is additionally connected to the frame by means of an expanding rod or compression spring, one end of which is pivotally mounted on the body

the lever, and the second end is pivotally mounted on the frame, while the lever and the additional lever are made in the form of a knee and form a hinged parallelogram with the sash.

Distinctive features of the proposed single-leaf pivoting door is that the lever is additionally connected to the frame by means of an expanding rod or compression spring, one end of which is pivotally mounted on the body of the lever, and the second end is pivotally mounted on the frame, while the lever and additional lever are made in the form the knee and form a hinged parallelogram with the sash.

The proposed device greatly simplifies the design, reduces the number of parts used, and, therefore, increases its reliability and durability.

The invention is illustrated by drawings.

In Fig.1 shows a lifting and swinging single-leaf door, Fig.2 is a view of the door lifting mechanism in the lowermost position of the sash, corresponding to section AA in Fig.1, Fig.3 is a view of the door lifting mechanism at one of the lifting moments sash, figure 4 is a view of the door lifting mechanism in the extreme upper position of the sash.

The lift-and-rotate single-leaf door contains (Fig. 1) a sash 1 with a handle 2, a frame 3, a lever 4 and an additional lever 5 connecting the frame 3 with the sash 1 on its lateral sides, an expanding bar 6 (see Fig. 2, 3, 4 ), hinges 7, 8, and 9 mounted on the frame 3, hinges 10 and 11 mounted on the sash 1 and the hinge 12 mounted on the body of the lever 4, and the expanding rod b is located between the hinges 9 and 12.

Lift-swing single-leaf door operates as follows.

(see FIG. 2), the force F from the expanding rod b to the side of the knee acts on the lever 4 at the mounting point of the hinge 12. The expanding rod 6 is between the hinges 9 and 12 constantly in a compressed state, regardless of its position during operation of the device, therefore, the forces arising in it are directed so as to push the hinges 9 and 12 apart, thus the expanding rod 6 acts as a compression spring . Component F1 of force F (see Fig. 2) presses the leaf 1 to the frame 3, in addition, the necessary clamping is ensured by the additional moment M around the hinge 7, which occurs in the knee of the lever 4 at the extreme lower position of the leaf 1. When the force F3 is applied to the handle 2, the sash starts to rotate and simultaneously rise upward (see Fig. 3), while the force F changes its direction and, thanks to the component F4, the sash 1 automatically rises. During the lifting of the sash, the lever 5, secured by hinges 8 and 11 respectively on the frame 3 and on the sash 1, prevents the latter from freely turning around the hinge 10 (Fig. 3), thus, the sash 1, the lever 4 and the lever 5 form together articulated parallelogram. In order to bring the hinge 9 as close as possible to the sash 1 (see Fig. 2), thereby providing the necessary balance of forces for pressing the sash to the frame in its lowermost position, the lever 5 is made in the form of a knee, therefore, during operation of the device, the hinge 9 does not interfere with the movement of the lever 5 (see Fig. 1 and 2). After this, the sash goes to its extreme upper position (see Fig. 4). In the extreme upper position of the sash, the component F6 of the force F in the expanding rod 6 does not allow the sash 1 to fall down under the action of its own gravity. The door is closed in the reverse order. A downward force is applied to the handle 2, the levers 4 and 5 are turned, the sash 1 is lowered and then pressed against the frame 3.

Claims (1)

A pivoting single-leaf door containing a sash installed in the frame, connected to the frame by each side by means of a lever and an additional lever, while the connection nodes of all elements are hinged, characterized in that the lever is additionally connected to the frame by means of an expansion rod or compression spring, one the end of which is pivotally mounted on the frame, while the lever and the additional lever are made in the form of a knee and form a hinged parallelogram with the sash.
