In the present publication, a closing system for trolleys has been described. The system consists of two arms 5, lying parallel with the side walls of the trolley, and a transverse support 6, which joins their other ends, and hinge joints 4, 7. The system is fastened in the upper section of the trolley in such a way that the arms 5 are hinged in the middle of the side walls. The transverse support 6 is coupled to the arms 5 by means of the hinge joints 7. In the usage position of the trolley, the transverse support is situated by the front wall of the trolley and locks the side walls of the trolley in place. In the storage position, the device has been turned rearwards around the hinge joints. The transverse support is now by the rear wall of the trolley and the hinge joints joining the transverse support 6 and the arms 5 allow the side walls of the trolley to be swung to the sides into the storage position. <IMAGE> |
