Abstract

The invention relates to devices for mutual fixation of twin flaps and can be used in construction. The aim of the invention is to improve the performance and simplify the design. On the outer flap, on the inner side, a C-shaped guide is attached. In the body of the internal sash, the lever is mounted with the possibility of rotation with a locking element at one end interacting with the shelves of the C-shaped guide. The locking element includes an oval elastic insert placed in the holder. At the opposite end of the lever there is a control element with a rotation limiter resting against the frame of the inner flap. 4 il.

Description

The invention relates to devices for mutual fixation of double sashes in the open position, namely sashes and balcony doors, and can be used in the construction of residential and public buildings.

The aim of the invention is to improve the performance and simplify the design.

FIG. 1 shows a node, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 - two twin sash with a locking device, general view.

The mutual fixation unit of the two leaves in the open position contains a guide 1 C-shaped, fixed on the outer window shutter 2 from the inside. In the body of the inner flap 3, a lever 4 is installed in the frame opening with the possibility of rotation around its longitudinal axis. At the end of the lever 4, facing inward, a control element 5 is placed with the help of a screw 6 and washers 7. The control element 5 has a rotation stop, made in the form of a two-arm lever, interacting with one

With its end 8, with the upper plane of the lower frame element of the inner flap 3, it forms an emphasis, and at the other end terminates with a handle 9. The locking element consists of a holder 10 with an oval hole, the axis of which is perpendicular to the axis of the lever 4. An insert 11 is placed in the opening of the holder 10 made of elastic material, made oval with symmetrical roundings at the ends. The guide 1 is attached to the flap with 2 screws 12.

The device works as follows.

For mutual fixation of the valves in the open position, open the inner 3 and outer 2 flaps. The control element 5 is rotated, with its help the insert 11 rotates the lever 4 so that the longitudinal axis is parallel to the axis of the groove of the guide 1, and the outer flap is brought in until the insert 11 is fully inserted into the inner cavity of the guide 1. The flaps are moved to the desired position and then the control element 5 is turned up to the stop of the rotation limiter 8 in the frame plane, while the elastic insert 1 is deformed in places of oval curves and turns

clamped between the shelves of the C-shaped guide 1, locking the sash in the desired position. The size of the oval of the elastic insert along the longitudinal axis is chosen larger than the distance between the shelves of the C-shaped guide, because of the reliable fixation (pinching) of the elastic insert in the guide. The width of the holder is chosen from the condition that it can be moved in the guide for self-alignment when the flaps are distorted during operation.

To disconnect the flaps, the control element 5 rotates the lever 4 and releases the locking element. Folds are unlocked.

When the control element 5 is placed in the middle between the extreme positions, the valves can be freely displaced relative to each other to change the opening angle without removing the guide element 1 from the internal cavity.

The use of an elastic oval insert as a fixing element allows the sash to be securely locked in the open position and allows it to be

when the flaps are fixed and released, and the use of the inner flap frame of the upper plane of the lower frame element as a supporting surface for the rotation limiter of the control element of the upper plane of the lower frame element makes it possible to simplify the design of the device.
