Description

The invention relates to commercial and technological equipment and can be used by retailers and catering.

The purpose of the invention is to increase the convenience of transportation and storage.

FIG. 1 shows a folding tray, general view; in fig. 2 shows the arrangement of the folding tray folded for transport and storage; in fig. 3. 4 - kinematic scheme of the folding tray in the foldable position; in fig. 5 is a kinematic diagram of the folding tray in the working position.

Folding tray contains table 1 with containers, made of pivotally connected with the possibility of rotation shield elements 2-5, rack 6 with umbrella 7 and legs 8, made of pivotally connected rod elements 9-12, installed with the possibility of rotation on both sides of the table. In the upper parts of the rod elements 9 and 10, the frame 13 of the umbrella 7 is fixed with a locking device in the form of a lever 14 and a stopper 15. At the same time, table 1 is equipped with a locking frame 16 with an additional locking device 17 that is hinged on a rod element 11 with an additional lock 17 legs placed a fixed rod 18, mounted behind the hinge with the possibility of contact with an additional latch 17.

One of the shield elements 2 of the container is hinged on one of the legs with the locking frame 16, and the last of the shield elements 5 is fixed on the other leg under the table 1. The supporting elements 19 and 20 constitute an additional capacity under the table. When delivered in folded form to the installation site, the tray is transferred to the working position by lifting the frame 13 (Fig. 3). In this case, the lever 14 rotates in the direction indicated by the arrow (Fig. 3), as a result of which the frame 13, resting on the stopper 15 (Fig. 4), forms a hard triangle B, which provides a preliminary fixation of the device. The tray in the pre-locked position is shown in FIG. four.

In order to fully fix and fix the tray in the working position, an additional lock 17 of the locking frame 16 is engaged with the fixed rod 18 of the leg element 12 (Fig. 5). At the same time, the shield elements 2 and 4, hinged to the locking frame, are transferred to a vertical position under the action of gravity and, resting against the shield element 5, fix the locking frame 16 (Fig. 5). Received three rigid triangles B, C, D in combination with the box-shaped structure of the tank formed by the shield elements 2-5 provide reliable locking and spatial stability and rigidity of the whole structure.

To transfer a folding tray from its working position to transport

0 withdraw the additional locking device 17 of the locking frame 16 from engagement with the fixed rod 18 of the element 12 of the leg, by first turning the shield elements 4 and 2 from the vertical to the horizontal position, freeing the locking frame for

downward movement and launching it into the position shown in FIG. 4. Thus, the hard triangles C and D are transformed into a movable hinged quadrilateral E, ready for folding. Then it is necessary to raise the frame 13 from the side of the lever 14. In this case, the lever 14, turning in the direction indicated by the arrow (Fig. 5), converts the hard triangle B into a movable hinged quadrilateral H (Fig. 3). After that the folding tray under

5, by force of gravity, spontaneously folds into the transport position.
