increase in the useful volume of the platform. The locking device of the hinged side 3 comprises a base 5j mounted on a rack A of the platform, an emphasis 6, a lever 7 fixed to the hinged side 3j, an intermediate link 8, one end of which is connected to the base 5 by means of a hinge 9, and the other end 10 is connected with lever 7, clamp-shaped stop 11, which is made integral with base 5 above hinge 9, and deactivate lock 12, mounted on the base of platform, B locked polo1

The invention relates to transport equipment, namely to locking devices designed to fix the sides of the cargo platforms of vehicles, in particular trucks, trailers and semi-trailers, in the working position.

The aim of the invention is to increase the useful volume of the platform.

FIG. 1 shows a cargo platform with the proposed devices, side view, FIG. 2 shows section A-A in FIG. 1, in FIG. 3 shows a section BB in FIG. 1 (at the working position of the device) {fig. 4 - the same, in the intermediate position, locking or unlocking the bead; in fig. 5 - the same, with an unlocked bead, in FIG. 6 is a view of B in FIG. 3

With the base of the platform 1 of the vehicle — a truck, trailer or semi-trailer — the hinges 2 are connected by folding the sides 3 and the rack 4 is rigidly connected. The locking device of the folding side 3 contains the base 5 fixed on the rack 4 of the platform, the stop 6 fixed on the folding board 3, lever 7, intermediate link 8, one end of which is connected to base 5 by means of a hinge 9, and the other end connected to lever 7 between its ends by a different hinge 10, integral support 11 at the same time Above the hinge 9 and deactivate the latch 12 mounted between the end of the lever 7 and

The lever 7 with its concave outer surface 14 is pressed against the inner sleeve of the supporting surface 13 of the stop 11, and with its inner supporting surface 15 presses the stop 6 of the flap 3 and the hook 19 at the lower end interacts with the clamp 16 of the clamp 12. To unlock the lower edge of the lever 7 tighten the base of the platform 1, then press down the clamp 16 of the retainer and turn out the released lower end of the lever 7. 6, or

base of platform 1. Stop 11 has a convex inner bearing surface 13, which is assisted with a concave outer bearing surface 14 of the upper end of the lever 7, which between the upper end and the hinge 10 has an internal bearing surface 15 that interacts with the support 6. The distance between the latch 12 and the hinge 9 is greater than the distance b between the hinge 9 and the clamp bracket 11. The latch 12 is located lower than the lower edge of the tailgate 3, and is made in the form of a swivel bracket 16 mounted on the base 1 and the flattened bottom plate Dinner 17. The bracket 16 has stops 18, limiting its movement upwardly from the horizontal operating position. At the lower end of the lever 7, a hook 19 is provided, cooperating with a bracket 16 passing through a horizontal elongated hole 20 at the base. The plate spring 17 has two legs resting on the stops 18 of the bracket and is attached by a rivet 21 to the base 1.

. The locking device operates as follows.

In the working position (Fig. 1-3), the lever 7 with its concave outer bearing surface 14 at the upper end is pressed against the inner convex supporting surface 13 of the stop 11, its inner supporting surface 15 presses the stop 6 of the tailgate 3 and interacts with its lower end with the bracket 16 clamp 12. Hook 19 on the bottom

the end of the lever 7 prevents the clamp bracket 16 from being accidentally exiting down from the horizontal working position. The stop 18 of the bracket 16 limits its movement upwards from the horizontal working position.

Due to the difference in sizes a and b, the force acting on the latch 12 is less than the force with which the stop 6 of the bead 3 acts on the lever 7, Overall Size and thickness of the device in the working position (Fig. 3) does not go beyond -. ly rack width 4 platforms 1 and a tailgate 3.

To unlock the bead, the lower-15 SRI ends the lever 7 towards the base of platform 1 (Fig. 3, dashed line), then press down the clamp bracket 16 and rotate out the lower end of the lever 7. 20 At the same time, the upper end of the lever 7 comes out of interaction with the stop 11 of the rack 4 and releases the stop 6 of the hinged side 3 (Fig. 4 and 5). Intermediate link 8 provides the required 25 movement of the lever 7. The side locking is performed in the reverse follower144

carry If the load pushes the bead outwards, the lever 7 pushes the bead 3 to the rack 4.

Claims (1)

Invention Formula A vehicle flap locking device containing an abutment fixed on the flap side pivotally connected to the platform base, a lever with a support surface for pressing against the side abutment and an intermediate link pivotally connecting the platform leg to the lever between its ends, characterized in that in order to increase the useful volume of the platform, it is provided with a clamp-shaped stop rigidly mounted on the rack of the platform without an emphasis on the tailgate, with the upper end of the lever being made a bucket for clamping its inner surface to the clamp-shaped stop, and the lower hook-shaped end of the lever is held by the lock-side lock fastener mounted on the base of the platform. 1 S 5 1324914 A-A FIG. 2 B b Bb 15 FIG. five View Compiled I.Magerramov Editor O.Golovach Tehred L.Serdyukova Proofreader S.Shekmar Order 3007/16 Circulation 566 Subscription VNIIPI USSR State Committee for inventions and discoveries 11.3035, Moscow, Zh-35, Raushsk nab., 4/5 Production and printing company, Uzhgorod, st.
