Cabinet-like piece of furniture

The innovation relates to cabinet-like pieces of furniture, also built-in wardrobes, and concerns a flap holder with friction brake. Such "devices are for that purpose been created to prevent the falling of flaps, e.g. B. folding tables, and thereby damage to the furniture and to prevent the fittings. The invention is based on the object of creating a flap holder, the braking effect of which is adjustable depending on the weight of the flap and also takes up as little space as possible. This goal is achieved with a flap holder, which is characterized by a round connecting rod articulated on the a furniture part, preferably the flap, is attached and slidable in a guide tube which is attached to the other

Furniture part, preferably the side wall of the compartment or the like, is articulated by means of a pivot plate that the guide tube and connecting rod can be rotated relative to one another are and at the inner end of the connecting rod axially screwable a threaded head bolt with adjoining the thread, tapered, to the fastening end of the pipe reinforcing shaft is attached, wherein on the tapered Shaft part of a brake sleeve made of elastic friction material sits and installed between the front end of the sleeve and the front end of the guide rod a pretensioned compression spring is. In the preferred embodiment of the flap holder, one end of the guide tube sits rotatably on a connector, which in turn is articulated on the pivot plate is attached, while the other end of the other diameter further tube is also on the connecting rod is led. The guide tube is expediently profiled on the outside, preferably made square, around it to be able to twist more easily when adjusting the braking force. Is placed between the front end of the guide rod and the connection part a helical spring embedded in the guide tube, it can serve as a locking spring, as in a tilting mechanism, if a screw-on bracket is attached to the flap in this way becomes that the point of articulation to the connecting rod when closing the flap over the connecting line between

Pivot pivot point and attachment point of the screw-on bracket is passed over.

Further features and advantages of the invention emerge from the following description of an exemplary embodiment, from the drawing and the claims for protection. It show:

Pig. 1 the flap holder attached to an only hinted at piece of furniture, with the flap in the open position State in full lines, in closed state in broken lines;

Pig. 2 shows a longitudinal section through the braking device;

Pig. 3 shows a modification to the fastening of the guide rod to the furniture flap;

4 shows a second embodiment in a side sectional view of the flap holder in the closed position of the flap.

With M, (Fig. 1) is the floor, with Mp a side wall the compartment on the otherwise not shown piece of furniture; K denotes the flap that is in the open position is drawn. The pivot plate 10 is screwed to the side wall Mp; 10a is the pivot pin on which rotatable the connection piece 11 with bearing bore 11a (Fig. 3) sits. A cylindrical extension 11b is attached to the connection piece 11, onto which the guide tube 12 is pushed and rotatable by a groove / cam connection Ilc / I2a, but

is not supported axially displaceable. In the pipe 12 leads the connecting rod 13, which in Pig. I illustrated embodiment is articulated at IJa on the bolt 14, which in turn is screwed into the flap K. At the inner end IJa of the guide rod, whose diameter is smaller than the inside diameter of the guide tube 12, a guide disk with the inside tube diameter is attached and partly in this disk, partly in the rod end, a screw thread 15a is attached, into which the head bolt l6 with its threaded part l6a is screwed in. Towards the head, the adjoining shaft part l6b thickens conically, and the brake sleeve IJ, which is made of elastic material, e.g. B. leather or a suitable plastic is made and can optionally also be slotted longitudinally. While play l8 is left between the bolt head and the sleeve, the other end of the sleeve, on which a pressure disc 19 lies, is pressed by the pre-tensioned compression spring 20 provided bore 12b fitting on the rod 13.

The whole thing works in such a way that when the flap is opened, the rod IJ is pulled out of the tube and,

supported by the compression spring 20, the cuff 17 is pulled more tightly onto the conical shaft part 16b, ie it expands and presses more strongly against the inner wall of the guide tube, that is, it brakes. In contrast, the
When the flap is closed, the rod 13 is pushed into the guide tube, and the sleeve 17 rubbing against the inner wall of the tube is removed from the cone 16b against the action of the compression spring 20
pulled down, ie can narrow, so that when
Closing there is essentially no braking force.

In order to adjust the braking force, the tube 12 is rotated; it takes the head bolt l6 over the brake sleeve 17 with and, depending on whether the braking force is to be increased or decreased, the head bolt l6 is deeper into the Thread 15a screwed in.

To a resilient locking of the closed flap
to effect, according to Fig. 3 and 4, the angle l40 is screwed to the flap K; its point of articulation l40a lies deeper in the interior of the compartment by the distance s, ie behind the connecting line between the pivot plate 10 and the base point l40b of the angle l40. The toggle spring is in the guide tube
l4l stored and their length and thickness dimensioned so that

before the flap is closed, the tilt position, d. H. Dead center, is reached, the tilt spring experiences its greatest compression while it is on its way can only partially relax until the flap is fully closed, so that its residual tension holds the flap shut.

Claims (4)

301 * 30. G. PROTECTION CLAIMS 1. Cabinet-like piece of furniture with a flap holder with friction brake, characterized in that a round 'connecting rod (13) articulated on a furniture part, preferably the flap (K) is attached and is slidable in a guide tube (12) which is attached to the other furniture part, preferably the side wall (Mp) of the compartment is hinged by means of a pivot plate (lO) that the guide tube (12) and the connecting rod (l ^) rotatable relative to one another and at the inner end (l ^ a / l5a) of the connecting rod A threaded head bolt (l6), which can be screwed axially, has a tapered head bolt (l6) that adjoins the thread (l6a) and extends towards the fastening end of the tube (12) is attached to the reinforcing shaft (l6b), wherein on the conical shaft part (l6b) a brake sleeve (17) made of elastic friction material sits and between the front end of the sleeve (17) and the front end of the guide rod (15) a prestressed Compression spring (20) is installed. 2.
