ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention is a swinging drawer that takes the form of an upper open compartment that is fastened to the underside of an upper wall cabinet/furniture such as, for example, an upper kitchen cabinet that is attached or hung on a wall.
A swinging drawer of this type is an advantageous complement to kitchen cabinets because it allows the existing space underneath the kitchen cabinets to be well utilized and can be subsequently attached to existing kitchen cabinets.
The task of the present invention is a swinging drawer of the aforementioned type, which can be attached to an open compartment on already existing kitchen cabinet and utilized immediately, is very accessible to the user and can be assembled easily and inexpensively.
The solution to the presented task of the invention is identified by the features declared in Protection claim

SUMMARY OF THE INVENTION
The invention is based on the swinging drawer that is fastened by means of assembly units that are located on one or both sides of the cabinet's/furniture's component side walls. The assembly unit includes a screw-down angle located on the cabinet side and a bearing plate located on the drawer side, so that both parts are connected hinge-mounted or swivel-mounted by a parallelogram linkage or rod.
The invention is advantageous because the assembly unit already contains the complete mechanism needed for the movable attachment of the swinging drawer to the cabinet; basically, no additional parts are necessary to fasten the swinging drawer to the cabinet. The swinging drawer can be assembled easily and, above all, quickly to the cabinet with the two assembly units, so that even a subsequent assembly of the swinging drawer can be accomplished at any time.
When the drawer is closed, the drawer's upper edge fits to the upper edge of the cabinet piece so that the upper open side of the drawer is covered by the cabinet piece, and the contents of the drawer are protected and covered. When the drawer is closed, the corresponding arms of the parallelogram linkages or rods are hidden because they are angled backwards directed towards the compartment.
In the open state, that is, when the drawer opens, it swings forward and outward and rises away from the cabinet's underside so that the length of the parallelogram linkages' or rods' arms and/or the position of its fulcrum in the screw-down angle and/or in the bearing plate are designed so that the swinging drawer, when open, is slightly tilted towards the user and projects out from the front edge of the cabinet component. This results in an advantageous ergonomic access to the contents in the drawer, as well as making the drawer's contents very visible and available to the user.
This special swinging-out and forward tilting of the open drawer is achieved because the front arm of the parallelogram linkage or rod, that lies closer to the front wall, is designed longer than the back arm. In order to keep the parallelogram linkage or rod stable, the respective arms can be connected together with the opposite-located assembly units by turn-connected or swivel-connected rods or linkages.
Especially when the drawers must carry heavy loads, the parallelogram rods or linkages are provided with a counterweight in the form of a torsion spring and/or draw spring. This counterweight prevents the heavily laden swinging drawer from suddenly swinging or falling down when the drawer is opened, but ensures that the drawer swings out slowly with the counter-force.
In another preferred embodiment, stops and/or support shanks, formed on the bearing plate, are located on the inner side of the back wall or, respectively, on the upper edge of the side wall of the swinging drawer, resulting in a slight alignment of the bearing plate during the assembly that stabilizes the fastening even more.
Advantageously, the opened drawer has at least one functioning, cushioning stop that absorbs the kinetic energy of the drawer when it swings out to the open position and reduces the speed of the drawer and brakes it.
In order to keep the drawer in its closed position on the cabinet, it has a locking device that is located in about the center of the front side of the drawer and has a pivotable, manually activated closing lever stored in a rocker system. When the drawer is closed, this catch lever engages with a closing angle that is provided on the cabinet side. The locking device is designed advantageously so that it is accessible (respectively, the access to the catch lever) in the drawer's bottom area, and also, so that it is easy and simple to activate. At the same time, the drawer can be opened by activating the catch mechanism manually.
