Furniture Having a Pull-Out Worktop

Abstract

A piece of furniture includes a base plate (12) formed by a top of a furniture body (10), and a worktop (14) adapted to be pulled-out, in which the worktop (14) covers at least a part of the base plate (12) and is slidably guided on a mounting plate (18) which is rotatably supported on the body (10) so as to be rotatable about a vertical axis (A).

Claims

1. A piece of furniture comprising: a furniture body including a base plate formed by a top of the furniture body, and a worktop adapted to be pulled-out relative to the base plate, and a mounting body rotatably supported on the body so as to be rotatable about a vertical axis, the worktop covering at least a part of the base plate and being slidably guided on the mounting plate.

Description

[0013] An embodiment example will be described in conjunction with the drawings, wherein:

[0014] FIG. 1 is a perspective view of a piece of furniture according to the invention;

[0015] FIG. 2 is a sectional view of a base plate, a mounting plate and a worktop of the furniture according to FIG. 1; and

[0016] FIGS. 3 to 7 are plan views of the furniture according to FIG. 1 in different configurations.

[0017] The piece of furniture shown in FIG. 1 has a body 10 a top side of which is formed by a rectangular base plate 12. A portion of the base plate 12 is covered by a worktop 14 which has also a rectangular shape and is arranged at right angles to the base plate 12 in the configuration shown here.

[0018] In the portion of the body 10 that is covered by the worktop 14, a rotary bearing 16 has been formed for bearing an approximately quadratic mounting plate 18 which extends directly above the top side of the base plate and is rotatable relative to the body about a vertical axis A that is defined by the rotary bearing 16.

[0019] Guide rails 20 are arranged along opposite edges of the mounting plate 18, and pull-out rails 22 are guided along a respective outboard side of each of the guide rails, the pull-out rails being secured to the bottom side of the worktop.

[0020] In the example shown the worktop 14 has a leg 24 which is rigidly attached to the work-top and is shaped as an inverted U-bow a horizontal top leg of which is aligned with and engages an edge of the worktop 14 at a smaller side thereof. The worktop 14 may therefore have a relatively large length without incurring a risk that the furniture will tilt when a load rests on the projecting part of the worktop 14. In the example shown the length of the worktop 14 is more than twice the width thereof.

[0021] In the example shown the body 10 has a box-shaped cupboard or container 26 which is supported on the ground with legs 28 and beyond which the base plate 12 projects on both sides. Disposed on one end of the base plate 12 is a side wall 30 by which this end of the base plate is supported on the ground, whereas the opposite end projects in cantilever fashion. A high tilt stability of the furniture is obtained due to the fact that the weight of the worktop acts as a counterbalance weight when a load is applied to the projecting part of the base plate 12.

[0022] Gutter-shaped recesses 32 are formed on the bottom side of the worktop 14 and extend in longitudinal direction thereof, and each recess accommodates one of the pull-out rails 22 and also forms a raceway for the associated guide rail 20 when the worktop is slid relative to the mounting plate 18.

[0023] FIG. 2 shows a cross-section of the base plate 12 and the worktop 14 in the vicinity of the rotary bearing 16.

[0024] The rotary bearing 16 has a bearing sleeve 34 which is embedded in the base plate 12 and into which engages a stud 36 that projects from the bottom side of the mounting plate 18. A circular groove 38, centered on the axis A, is formed in the top side of the base plate 12, and two diametrically opposite guide cams 40 which project from the bottom side of the mounting plate 18 engage in the groove. Four pockets 42 are formed at the inner peripheral edge of the groove 30 in angular spacings of 90°. These pockets accommodate elastic detent devices 42′ (see FIG. 1) in which the cams 40 may snap-in when the worktop 14 reaches an angular position in which its edges are parallel to the edges of the base plate.

[0025] It can further be seen in FIG. 2 how the guide rails 20 and the pull-out rails 22 are accommodated in the recesses 32 of the worktop 14. The guide rails 20 are attached to upwardly bent edges of the mounting plate 18. The two recesses 32 of the worktop 14 are interconnected by a shallower recess (no reference numeral) which essentially accommodates the mounting plate 18, so that only a relatively narrow gap is formed between the bottom side of the worktop 14 and the top side of the base plate 12.

[0026] FIG. 3 shows the furniture in a configuration in which it has the smallest footprint. In the example shown the worktop 14 (without the leg 24) is congruent to the base plate 12. In the configuration shown in FIG. 3 the baseplate 12 is entirely covered by the worktop 14. The leg 24 directly engages the side wall 30 of the body in this configuration.

[0027] FIG. 4 shows the furniture in a configuration in which the worktop 14 has been pulled-out to the left side, so that the worktop 14 and the base plate 12 together form an increased support area.

[0028] In FIG. 5 the worktop 14 has been rotated, in the pulled-out position, by an angle of approximately 45° about the axis A. The leg 24 is spaced so far away from the axis A in this configuration that it does not abut at the corner of the base plate 12.

[0029] In a modified embodiment the worktop 14 could also have a somewhat larger length than the base plate 12. In that case the pull-out length of the worktop could be so large that, in the pulled-out position, the worktop could be rotated by an angle of 360° about the axis A without abutting at the base plate 12.

[0030] FIG. 6 shows the furniture in a configuration in which the worktop 14 is rotated by an angle of 90° relative to the base plate 12, but in opposite direction as compared to FIG. 1, so that the configuration according to FIG. 6 is the mirror image to the configuration shown in FIG. 1.

[0031] Even in this angular position, just as in any other angular position, the worktop 14 may be slid relative to the mounting plate 18. As an example, FIG. 7 shows a T-shaped configuration in which the worktop 14 has been pushed back, from the configuration shown in FIG. 6, so far that it projects beyond the baseplate 12 by equal distances on both sides.
