SU1618861A1 - Device for fixing recoiling flap - Google Patents

Abstract

The invention relates to railway transport and allows to increase the usability of the device by eliminating the need to maintain the latch at the time of opening and closing the sash. The device is mounted on the sliding doors of a covered freight car. The device consists of a latch, hinged by means of an axis on the bracket, which is rigidly fixed on the leaf. If it is necessary to open the closed sliding door, the latch must be turned to the leftmost position by rotating it around the axis in an anti-clockwise direction. Then the flap is moved to the right (open). After passing the stop, the latch 6 lowers to the extreme left position and locks the flap open. 4 il.

Description

The invention relates to railway transport and can be used in the construction of doors for box cars.

The aim of the invention is to improve the usability of the device.

FIG. 1 shows the sliding doors of a covered freight car, the doors are locked in the closed position; in fig. 2 — node I in FIG. one; in fig. 3 shows section A-A in FIG. 2; in fig. 4 - locking device when opening the sliding door.

The device is mounted on sliding doors 1 and 2. of a covered freight car and communicates with stops 3 (the positions of doors 1 and 2 are closed, Fig. 1) and 4 (the position of the doors 2 is open, Fig. 4) fixed rigidly on the rail 5.

The device consists of a latch 6, a bracket 7 and an axis 8. The latch 6 is a plate at one end of which there is a hole for the axis 8, at the other - a symmetrical triangular notch 9 relative to the longitudinal axis of the latch 6. The hole for the latch 6 for the axis 8 is made at a height h from the projection of the bracket 7. The protrusion 10 of the bracket 7 limits the rotation of the latch 6 around the axis 8, determines its symmetrical position relative to the vertical, and ensures that the triangular cut of the latch 6 engages with the stops 3 in the extreme right (closed position of the sash 2, Fig. 1, and the stops 4 in the leftmost (open position of the flap 2, Fig. 4) positions.

The bracket 7 is rigidly fixed on the legs 1 and 2 of the car, in the ledge 9 of the bracket there is a hole 11 for the lever (scrap, etc.) when opening or closing the shutters 1 and 2 in the event of a door jamming during operation.

The device works as follows.

If it is necessary to open the closed sliding door 2 of the car (Fig. 4), the latch 6 must be turned counterclockwise around its axis 8 to the leftmost position, which is limited by the projection 9 of the bracket 7. Then the door 2 is moved to the right (open)

about

if necessary, you can use a lever (scrap, etc.), insert it into the hole 11 of the projection 10 of the bracket 7 and then into the hole of the rail 5, etc. As the sash 2 moves to the right, the latch 6 passes through the stop 3 and then the stop 4 is raised, rotated clockwise at a slight angle, and after passing the stop 4, the latch 6 is lowered to the extreme left position and locks the flap 2 in the open position.

If it is necessary to close the flap 2, the latch 6 is moved to the extreme right position by rotating it clockwise. When the flap 2 is moved to the left (closing), the latch 6 locks the flap 2 in the closed position (Fig. 2).

The process of opening-closing of the leaf I is similar to the opening-closing of the leaf 2

The use of the proposed device will improve the convenience when opening and closing the sliding leaf. When installing the device on the sliding doors of the car, there is no need to support

-

Wan latch the hand at the time of opening and closing the sash until the latch does not come out of engagement with the stop, which simplifies the process of operating the device.
