SU29486A1 - Hatch cover for freight cars - Google Patents

Description

The invention is from hatch covers for goods cars made in the form of a square and equipped with anti-spontaneous opening devices.

In the proposed gate, the bottom shelf 3atBopa is extended by using a swivel plate, which, in the closed position of the hatch, rests against the hinge fastened on the hatch flap, and from the top end to the pin on the bolt leg itself. The stop for the upper end of the plate can be made by touching the perpendiculars of the limb plate with the side edge of the bolt foot and turning the grandchild) on the leg of the bolt to provide a slit with which the oria can slide along the leg held by the guide pin.

In FIG. 1 is a front view of the shutter; FIG. 2 is a side view of it; FIG. 3 is a front view of a modified form of the implementation of the shutter, equipped with a plate with a bend; FIG. 4-g-side view of FIG. 3; FIG. 5 is a front view of a modified form of a shutter provided with a plate sliding along the shutter foot; FIG. 6 same

in the side view; FIG. 7 detail of the movable plate.

A hatch cover for freight cars is supplied on its lower leg (I), with a plate 2, rotatably fixed. on axis 5 so that one end of the plate can protrude beyond the outline of the lower edge of this leg of the bolt, extending it in the vertical position of the leg 7 and plate 2. At the upper end of the plate 2, in its vertical position, on the leg / fixed fixed pin 4 , and at the level of its lower end, a fixed pin 5 is fixed on the hatch flap, orb than both of these bolts, when the hatch is in the closed position, are located on the right side of the leg 7 (Fig. 1) and are intended to prevent the leg 7 from turning in this direction to open the bolt.

A modified form of the gate provides (Fig. 3 and 4) replacement of the pin 4 in FIG. 1 by bending 4 on the plate 2 itself so that this bend is located on either side of the leg 7 when the shutter closes and also prevents it from turning to the right. - In another modified form of the gate (Figs. 5, b and 7), the rotatable njf card is provided with a segment slit 5,

with which it can not only turn on the pin 3, but also slide along the leg. The lower end of the plate 2 is provided with a bend 6 to grip the plate with its hand during its vertical movements along the leg /.

By the basic form of the gate (Fig. 1. And 2) and by the modified form shown in FIG. 3 and 4, when closing the shutter, plate 2 bends around pin 5, turning on axis J, and, in the vertical position to the left of pin 5, prevents the leg from moving backward / to the right while the car is on the way. In the closure of FIG. 5, 6, and 7, a similar removal of the lower leg / bolt to the left of the vertical when the hatch is closed in order to insert plate 2 by pin 4 is impossible and therefore plate 2 is provided with a slit 5 for lifting. For the foot to slide on it / the vertical position of the plate 2 could take its position to the left of the pin 4 by sliding it back down the leg 7,

The subject matter of the invention.
