Description

The gates of retractable doors, for example, railroad wagons, equipped with a secret lock with a U-shaped plug-in handle and a system of hook-on washers coaxially with one of the legs of the handle, are known.

In the described gate, the leg of the bow of the Zemk, rigidly connected with the housing to the door opening, is made in the form of a pin through the eyes of the door and eyelet on the door opening. In addition, to use the lock of the proposed gate as a control, a specially shaped flat seal is used, inserted into the slot of the lower end of the handle leg at the lower position of the latter and locked in the raised position, at which the handle is held by the upper lock washer.

The proposed shutter is designed to replace wire twists with. lead seals, for them, for locking the doors of freight cars. The shutter reliably locks the doors and, in addition, due to the presence of a seal, provides control over the safety of goods.

Knowing the digital cipher to install hook washers, you can open and close the bolt without a key.

If necessary, for example, when locking empty cars, the lock code can be declassified by means of a special top washer.

FIG. 1 shows a general view of the proposed shutter; in fig. 2 - the same, side view; in fig. 3 - view of the castle from above; in fig. 4 is a partial section of the lock along hooked washers (along the line AB of FIG. 3); in fig. 5 - view of the hook washer from above.

The shutter consists of a lock with a retractable shackle attached to a rack of a doorway and a set of coaxially hinged washers cooperating with the right (according to the drawing) leg, a top washer designed to hold the shackle with a seal in the upper polishing

or, for locking, a lock with an open cipher on the hook washers and a stop (bracket or eye) attached to the sliding door, for which the other locked leg of the handle is kept locked by the door.

A cylindrical body / lock with a side slot for turning and viewing hook washers and with the top 2 and bottom 5 strips attached to the rack of the doorway through the corners 4 and bolts 5.

Several hook washers 6 (four washers are shown in the drawing) fitted with a central hole 7 with a side cut 8 for the passage of the right leg of the bow 9 with side pins 10 are located in the housing / coaxially and swivelly. Figures 11 and 12 notches are located along the forming washer make it easier to turn the washers by hand or with a key when they are stuck in the case.

The U-shaped arm 9 freely passes through the holes in the slats 2 and 5 and through the washers 6, when the latter are installed according to the cipher 14, is selected on the strap 2, when the notches of the 8 washers are installed against the side pins 10 of the bow. Subsequent arbitrary rotation of the washers 6 closes the handle in its lower position.

At the bottom of the right NOL4KI handle 9 there is a slot with a widening at the top, into which a seal 16 can be inserted. The seal is made of thin sheet steel with a thickening at the top, formed by twisting its upper end and preventing it from being pulled down from the slot of the leg downwards (not shown) . To insert the seal 16 into the slot, the legs of the arms 9 together with the washers 6 are lowered downward, compressing the spring 18; while the slot goes out. After that, the spring 18 lifts the washers 6 with the handle and the upper end of the seal enters the hole of the strap 3.

When the handle is raised in a high position, its pin 19 extends outside and is located above the upper washer 20, coaxially and pivotally fastened to the leg. The washer 20 has a side cut-out for the passage of the pin 19, a through-hole 21 through which, at one of the positions of the washer, pin 14 on the plate 2, the sleeve 22 attached to the washer, covered by the top of the cap 23, and the pin 24 freely placed in this sleeve is viewed. In the bar 2 there are two holes 25, one of which, when the washer 20 is turned, can pivot the pin 24 free of which the washer 20 can turn.

The left leg of the handle 9, with the lower locking position, is set in the path of movement of the stop-grip 25 attached to the sliding door, which prevents the latter from opening. When the handle is lifted upward, the eyebolt 26 passes freely between the bars 2 and 5, and the door can be opened.

When the handle is in the upper position, its pin J3 is pulled out through the side cut-out 15 in the pivoting jaw 17 and can be held over the washer during its subsequent rotation.

To open the lock, the swivel washers 6 are installed according to the conditional cipher, and the seal is broken. On the extended lower end of the seal can be squeezed out with filling tongs, for example, the station name, date, number, etc.
