27.08.96 DB/Ha Furniture pull-out

The invention relates to a furniture pull-out in a design according to the preamble of claim 1.

In conventional furniture pull-outs, the pull-out rails are firmly connected to the pull-out body by screwing, welding or riveting. This connection process is a separate work step that increases the production costs of the furniture pull-out.

The invention addresses the problem of simplifying and reducing the cost of the manufacture of furniture pull-outs and solves it by means of a furniture pull-out in the design according to claim 1. With regard to further embodiments, reference is made to claims 2 to 8.

The furniture pull-out according to the invention is only provided with the projections on the pull-out body by the manufacturer and is only combined with the pull-out rails, which form a supplied part, during assembly in the furniture body, whereby the connection between the pull-out body and the pull-out rails can be accomplished with a single movement. Equipping the connecting body only with projections simplifies and reduces the cost of production.

without requiring any significant additional effort during assembly. In the connected position, the pull-out rails assume an exact position, which is retained when the pull-out rails are inserted into the rail guides in the furniture body.

Further details and effects emerge from the following description of an embodiment of the subject matter of the invention and the drawing. The drawing shows:

Fig. 1 is a diagrammatic representation of a pull-out body according to the invention with pull-out rails shown separately in different pivot positions, and

Fig. 2 is an enlarged, broken-open front view of the furniture body with attached pull-out rails, parallel to the pull-out direction.

The furniture pull-out shown in the drawing comprises a pull-out body 1, which is preferably designed as a wire construction as shown and can have the shape of a grate or basket. The base of the pull-out body 1 is formed by cross wires 2, 3. The cross wires 3 project with their ends over the cross wires 2 on both sides of the pull-out body that are parallel to the pull-out direction 4 and accordingly provide projections 5, which are preferably hook-shaped.

In detail, the projections, seen parallel to the extension direction 4, have the basic shape of a Z with an outer leg 6 at the top and an inner leg 7 at the bottom. The outer and inner legs 6,7 each run horizontally. The inner leg 7 has a projection 8 at its inner end, which

horizontal support area of the inner leg 7 is limited on the inside and is formed by a bend towards the main part of the cross wire 3.

In the example shown, three cross wires 3 are provided distributed over the length of the pull-out body 1, but depending on the requirements, two or more than three cross wires 3 presenting the projections 5 can also be provided.

The cross wires 2, 3 are fixed to longitudinal wires 9, the upwardly bent ends of which are connected to a railing 10. In the area of the front sides, the longitudinal wires 9 are each provided on the outside with a further cross wire 11, the ends of which can provide stop surfaces 12 for pull-out rails 13, 14 when these are combined with the pull-out body 1 and are in the connected position.

The pull-out rails 13, 14 have a substantially L-shaped cross-section and accordingly one leg 15 or 16 that is aligned horizontally in the connecting position and one vertically in the connecting position. They are provided with a roller 17 on the outside of their leg 16 that is vertical in the connecting position at the end facing away from the pull-out direction 4 and are guided with the help of this roller and a roller on the rail guides (not shown) attached to the furniture body along the rail guides in and against the pull-out direction 4.

In the area of their legs 15, the pull-out rails 13, 14 are provided with openings 18 which are arranged in such a way that when the pull-out rails 13, 14 are placed on the projections 5 of the pull-out body 1, these projections cover the openings 18 from the underside of the legs 15 of the pull-out rails

13,14. After placing them on the projections 5, the
Pull-out rails 13,14 are folded into their connecting position, in which the lower inner leg 7 engages under the underside of the leg 15, the
the upper outer leg 6 overlaps the upper side of the leg 15 and the connecting leg 19 between the outer and inner legs passes through the opening 18 assigned to it. The projections 5 secure in the connecting position
the fixed position of the pull-out rails 13,14, which can rest against the stop surfaces 12 of the pull-out body 1 in the connecting position, but do not have to do so for positioning. In the connecting position
This creates a fixed position between the pull-out rails 13, 14 and the pull-out body 1, which is maintained by the guide rails in the cabinet body after a furniture pull-out has been inserted into the cabinet body.

The attachment of the pull-out rails 13,14 can be carried out in a single movement during assembly and eliminates the need for a manufacturer-side, necessarily fixed connection between the parts, which would require an additional connection operation.
required. When the pull-out body 1 is designed as a wire construction
The formation of projections on the extractor body 1 is particularly
easy and inexpensive to implement. But even with pull-out bodies made of wood or plastic, it is possible to attach the required projections to the pull-out body, so that the invention can also be used with such constructions.

Slide rails such as the ones shown are usually in the range
of its ends and in the middle area of its leg 15 with holes for the passage of fastening screws, so that on sides

of the drawer manufacturer, the position of the projections only needs to be adjusted to the commercially available drawer rails and their holes.
