Description

For locking the arrow points, it is known to use rotatable bolts, which collapse when turning the corresponding cutout of the switch rod. In the proposed snap of the heck is made in the form of reinforced on. The frame arm of the two-arm lever, one shoulder of which is inserted into the notches of the crossbar attached to the gutter, and the second shoulder is used to fix the lever in the set position with the help of a locking screw.

The proposed switch closure of the switch hole is designed to ensure that the hole is firmly secured in the desired position, while avoiding the need for commonly used security locks.

In FIG. 1 is a side view of the closure; FIG. 2 - its top view; FIG. 3-section on A5 in FIG. one; FIG. 4 is a CD section of FIG. one.

On the frame rail 7 arrows from the outside of his side on the bolt 8 attached double-arm lever 2. freely rotated 180 °. A bolt 5, which passes under the frame rail and has two notches, is tightly attached to the sole of the switch-and-sharpening edge J3. One or the other of these cuts, viewed by the position of the switch-bit, includes one shoulder (head) of the lever 2 at its position shown in FIG. 1 and 3. For pre (339)

To prevent the bolt from moving spontaneously to the side or lowering it down, a collar attached to the base of the frame rail serves. To close the lever 2, a locking screw 3 is used, which is seated in the bracket 4 attached by a bolt 9 to the frame rail on its outer side. This screw at one end has a triangular head for the same key, and the other end, when screwed in until it fits, enters the corresponding slot in the lever 2.

The action of the circuit is as follows. In the position shown in FIG. 1, 2 and 3, the head of the lever 2 enters the cut-out bolt 5 closest to the frame rail. The sharp edge is closed in the position adjacent to the frame rail, and the lever 2 is fixed in its position by the screw 3.

To translate its sharp position, it is necessary first of all to unscrew the screw 5, freeing the lever 2, then turn the lever 180 ° around the bolt 8, thus withdrawing its head from the cutout in the bolt 5, thereby releasing it sharply. After transferring the shaft to its other position, it closes in it in the same way as in its first position, with the only difference that the head of the lever 2 enters at the same time into another notch in the transom 5.

The subject matter of the invention.

The switch handle switch, consisting of a rotatable latch, which falls into a cutout, which is located on a bolt attached to the edge, which is made in the form of

mounted on a frame rail 1 of a two-arm lever 2, for fixing the position of which with a closed sharper serves a locking screw 5, screwed into the corresponding slot in the body of the lever 2.
