Description

The invention relates to fuse devices used in tram cars, consisting of rubber tubes, deployed under the action of air injected in them, and sierted under the influence of the springs placed under them. In the proposed device, the individual tubes are placed in the cells of the bag that unites them, when the tubes are deployed under the action of compressed air, a continuous sheet extending over the rails in front of the tramcar.

In the perspective drawing, FIG. 1 shows a view of a part of a tram car with a folded device; FIG. 2- the same, with the deployed device; FIG. 3-view of a separate tube; FIG. 4- spring; FIG. ; 5-tube unifying tube; FIG. 6 is a section of the air flow crane; and FIG. 7-side view of spring placement.

In a bag (chamber) / made of durable rubberized tarpaulin full-length stitched to form separate longitudinal cells, slaughter straight-line tubes 2 (Fig. 3) are inserted, sealed with a SINGLE-END and having a different end of 24A from the end. -:.

feces or canvas. Under each tube

(Fig. 7) is inserted into the steel chamber.

flat twisted spring 3 (Fig. 4),

a rivet hole at the end,

attaching it to the end of the chamber.

Then the second rubber tube is re-inserted into the next cell, then the second spring (curled in one direction from the first) and t, d., To the other edge of the bag. This bag, fitted with rubber tubes and springs, is connected to a metal air tube 4 (Fig. 5), with the outward ends of the tubes 2 fixed to the branches 4a of the tube 4. The tube 4 thus connected to the bag is strengthened with a possibility of turning on the corner frame, which, in turn, is attached to the car body. To the same frame, the outer ends of the springs 3 are attached with screws.

Two trays S (Fig. 1) are bolted to the sides of the front strut to hold the entire pneumatic safety device. Each nest has a bolt P; the employee locks the buffers 10 (Fig. 5) and the frames embedded in their sockets. By installing in place raiki with. with a bag, the rear upwardly bent appendage // of the tube f (Fig. 5) is connected by means of a flexible hose / 2 (Fig. 1) and connecting joints 73 to the air passage. The iron buffer 10 with the bag put on it and the bag. The bag presses down the pismatical buffer and serves as an addition to the adaptive fixture. The air bag J4 is supplied with a rubber chamber and has sides to fix it with lacing on the buffer, pc 10. Air filled with air, the corresponding valve bag 14 takes on a cylindrical shape with the horses bent backwards (Fig. 1). To activate the fixture on the driver’s platform, an air brake is connected to the air duct, connected through valve J5 (Fig. 6) and flexible hose / 2 to the fixture. The crane has a lowering 75a and an outlet of Hoii 156 to 1 for air. The channel in the tap of the crane has a widening on the output side / 5 a. In order to actuate the device, it is only necessary to open the valve, the stopper of which is in the position shown in FIG. 6. Air under strong pressure through the valve channel and the hose rushes into the bag, all the chambers of which are filled with air, as a result of which the bag unfurls. ejected forward as a cushioned canvas. The front edge of the latter, in order to avoid rapid wear during ejection and from slipping along the path, should be strengthened with a material suitable for this purpose at the bottom, for better sliding, smooth Rounded should be attached. Pieces of some P {wood fiber, aluminum, or other fiber. Approach of this material., nn. In the event that a person is lying, on his way, then the ejected canvas will cut him off and take it upon himself; if; i: e the person is on his feet, then the canvas will beat him with a soft blow and will also interrogate himself, or, finally, if the person seems to be at a distance very close to the carriage, then when the crane is opened, in deployment time, the device is struck From the bottom, he will reject the person, iine "rsd, and nptf further promotion. Xnii can pick him up. In order to remove the fixture, it is only necessary to close the air valve with the same handle, the stopper of which, turning in the opposite direction, closes the inlet of the air duct, and its broad outlet hole communicates the fixture with the atmosphere. When the air leaves the bag, the latter, under the influence of the twisting springs, coagulates to its original position. The subject matter of the invention., 1. A safety device for tram cars, provided with an elastic front mesh, characterized in that the individual rubber tubes 2 (Figs. 2 and 3) are placed in a kayer (bag 7) divided into appropriate cells (a bag 7), forming a solid canvas that unfolds when the tubes are filled with compressed air and coagulated under the influence of springs 2. The form of the device according to claim 1, characterized in that the springs (Fig. 4 and 1) are placed between the tubes inside the chamber 7. 3. The form of the device; . 1, distinguished by that. springs. 3 (Fig. 7) are placed under the chamber /, being connected with non-AHUtb in the lower end portion. . ;,:
