LT6760B - A loop latch - Google Patents

Abstract

The invention relates to mechanical devices, namely latches. A loop latch consisting of a rope loop (3) and a latch (4). Thin enough to fit between the strung parts of the frame and the sash, a locking rope (3), bent in the form of a loop and fastened to the frame (1), and on the sash (2) from the inside of the room - centrifugal rotation of the original oval rope (4) , which, when rotated, hooks and rigidly tightens the loop of the rope, firmly connecting the frame to the sash, and prevents unauthorized opening of the window (door, gate).

Description

The invention relates to mechanical devices, namely latches.

The loop latch is designed to protect doors, gates or windows from unauthorized opening.

Nearest analog: EP2733289A2.

The analogue consists of a rope, a stationary part of a window (door, gate), further a frame, a fastening element and a moving part of a window (door, gate), hereinafter a sash fastening element, and one of the fastening elements has a lock securing one end of the rope.

Disadvantages of the analogue: the construction of the analogue is not tight enough and resistant to breakage, as it allows the window (door, gate) to be useful, because the rope is not fully tensioned and does not compress the sash with the frame rigidly, and the sash with the frame locked, one end must be locked, and this makes the whole analogue quite complicated and expensive. Also, the construction of the analog does not allow it to be attached where the opening edge is closer to the sash than 20 mm.

The object of the invention is to create a latch of a new construction, which would be simpler and cheaper than the analogue, and it could be attached to windows, gates and doors of any construction.

The object is achieved by choosing a thin, 0.5 mm to 5 mm thick enough to fit between the strung parts of the frame and the sash, a lanyard that folds them into a loop and is attached to the frame, and on the sash from the inside of the room to the original oval shape. a rope retainer made by 3D printing which, by rotating, hooking and rigidly tightening the loop of the rope, firmly connecting the frame to the sash.

The object of the invention is illustrated in the drawings.

FIG. 1 shows an unlocked latch

FIG. 2 shows a locked latch.

FIG. 1 shows a rope 3, a bent loop fastened by screws 5 on the frame 1 and a rope retainer 4, fastened to the sash 2 by a screw 6 and turned longitudinally towards the opening. The rope 3 is thin enough to fit between the strung frame 1 and the sash 2 and into a very small space between the sash 2 and the opening. Unobstructed on the latch 4, the rope 3 does not lock the frame 1 and the sash 2, and allows the window (door, gate) to open freely.

FIG. 2 shows a rope 3, a bent loop, fastened to the latch 4, and the latch 4 is longitudinally pivoted from the opening edge, rigidly locking the frame 1 and the sash 2.

Advantages of the device provided by the invention: due to the original construction the latch can be used on any type of hinged structures. Using 3D printing technology and original components, the manufacture of the latch becomes significantly cheaper than the analogue, and the latch itself provides more protection against sash breakage.
