Description

The present invention relates to a turntable device for

  cupboards, .comprising a pivoting column, an upper bearing plate and a lower paying plate, at least one turntable fixed on the pivoting column and comprising a sector-shaped cutout for the interlocking of sections of driven facade panels in the rotation of the column and a stop mechanism comprising a fixed latching plate and a latching element driven in the rotation and

fixed in an elastic manner.

  Turntables are known and are used mainly in kitchen cupboards which are only partially accessible from the front as they form a dead corner between two facades of

  cupboard arranged perpendicular to each other. The turntables

  known nants consist of a pivoting column, arranged vertica-

  which is connected on the one hand to the bottom and on the other hand to the upper face.

  - top (top) of the cupboard and on which one or more are fixed -

  circular plates (turntables) which include a cut in

  form of sector of 90, the two boundary surfaces of which extend parallel

  Lately to the respective facades of the cupboards coming to apply one against

the other in the corner.

  So that the sector-shaped cutout always remains exact-

  In the same position when the two sides of the sector-shaped cutout of the turntable are arranged parallel to the fronts of the cupboards, there is provided, in a known turntable, a ball catch mounted on the pivoting column, by the through a console fixed thereon, the axis of action of this latch extending parallel to the axis of rotation of the pivoting column. A latching part comprising a V-shaped cutout is mounted on a first branch of a U-shaped sheet metal part; the second branch of this piece of sheet metal is fixed above the cupboard. To adjust the retaining force when snapping in

  of the ball catch in the V-groove, one can on the one hand move axia-

  Lement the latch on the support and we can also adjust the axial position of the console on the pivoting column after loosening a locking screw. The adjustment of this ball catch must be carried out individually on each box or cupboard, since its relative position relative to the latching groove depends on the dimensions of the cupboard or the manufacturing tolerances of the latter in height. This involves time-consuming work which leads to high costs in the mass production of kitchen furniture and makes most

  of the time required for installation, a later adjustment.

  In a known device with a turntable, it is mounted, on the upper bearing of the column which is screwed under the top of the cupboard,

  a cam on which a roller fixed on the facades can move

  angled (US-A-3,281,197). This device has the disadvantage that a precise alignment of the facades of the rotary element on the facades

fixed neighbors is not possible.

  In order to remedy these drawbacks, the invention aims to provide a turntable device in which the stop mechanism can be mounted and adjusted in a simple manner, the locking force cannot be influenced by the tolerances existing in the closet or

on the turntables.

  The invention further aims to keep the facade panels exactly parallel to the neighboring facades when the cupboard is closed, that is to say when the pivoting mechanism is locked, regardless of the magnitude of the load applied by the objects deposited on the

turntables.

  To this end, the invention relates to a tray device

  turning of the type indicated at the beginning, characterized in that the locking element

  quêtage is arranged so as to be secured in rotation with the pivoting column and in that the latching plate comprising the means

  snap is fixed on one of the bearing plates.

  The new turntable device can be produced economically and reduces assembly and adjustment times. The set of force application bodies which. are necessary for locking are located inside a closed fitting, thus not interfering in any way nor the

closet, nor the turntable.

  The invention will be explained in detail with, in support, an embodiment shown in the drawings, in which:

  Figure i is a perspective view of the entire arrangement

  sitive with a turntable, the cupboard being omitted, FIG. 2 is a side view of the console comprising the ball catch (having a partial cutout), FIG. 3 is a top view of a support for facade panels with sliding fixing brackets and Figure 4 is a side view of the flange and the slide

  for guiding the support of front panels in Figure 3.

  The turntable device (s) of Figure 1 is cons-

  made up of two turntables 1 which are mounted, at a certain distance from each other, on a pivoting column 3 so as to be

  united in rotation. The pivoting column 3 is mounted so as to be able to rotate freely, at its lower part on a plate 5 and at its upper part on a plate 7. The arrangement of the bearings located on the plates 5 and 7 is not part of the invention and is therefore neither explained nor shown in detail. Similarly, the fixing of the two turntables 1 on the pivoting column 3 is not part of the invention. A snap plate 9, which can constitute a part

  integral with the upper plate 7, is mounted on the latter sensi-

  at a right angle and has a slot-like recess 11, or a recessed portion or a groove, extending parallel to the axis

  of rotation A of the pivoting column 3 and serving as a latching means

  floor. To fix the lower 5 and upper 7 plates on the bottom or under the top of a cupboard (not shown), there are provided holes 13 intended for the passage of screws 15. In the region of the recess 11, a console 17 of angled shape is fixed on the pivoting column 3, for example by means of a clamping screw 19. A ball catch 23 (see FIG. 2), of essentially conventional structure, is mounted on the vertical branch 21 of the console 17 and its position is axially adjustable by means of a thread 27. The displacement axis B of the ball catch 23 is directed radially with respect to the axis A of the pivoting column 3. The ball catch 23 is preferably consisting of a cylindrical sleeve 25, one end of which is provided with a bottom and which externally comprises the

  thread 27 by means of which this catch 23 can be screwed into a tap.

  corresponding dage provided on the console 17 and be moved axially there. A helical spring 31, which bears from below on a ball 33, is housed

in the cavity 29 of the sleeve 25.

  Above the turntable 1, a support for front panels 35 (see FIGS. 3 and 4) is fixed to the pivoting column 3. The

  front panel support, more simply called support 35, is immo-

  stabilized on the pivoting column 3 by means of a flange or collar 37 and it can be moved axially after loosening a screw 39. At the upper part of the flange 37 and / or at its lower part, there is provided a notch 38 intended to receive a finger 42 located on the pivoting column 3. The support 35 consists of a slide 41, extending substantially radially with respect to the axis A, in which is fixed, on each of its two sides and so as to be able to slide therein, a fixing stirrup 43 comprising a bent end 45. The fixing of the two stirrups 43 is carried out by means of a screw 47, passing through the stirrups 43 and the support 35, and a nut 49. So that the two fixing brackets 43 can move parallel to each other,

  the slide 41 comprises, at each of its upper and lower parts

  upper, a sliding edge 51 disposed perpendicular to the slide

  safe. So that the fixing stirrups 43 can move in the radial direction relative to the pivoting column 3, buttonholes 53 are provided in the two fixing stirrups 43. In the two ends 45

  of the stirrup 43, there are provided through holes 55 used for fixing

  tion of the front panels 57 of the cupboard not shown, one of the holes being able to have the form of a slot in order to allow a fine adjustment of the position of the front panels 57 (FIGS. 3 and 4). The ends 45 at right angles to the fixing stirrups 43 are parallel to the two limit surfaces 59 (FIG. 1) of a sector-shaped cutout 61 provided on the

turntable 1.

  The operation of the turntable device is described below. It is between the lower plate 5 and the upper plate 7 which are fixed to the bottom and under the top of a cupboard, that the pivoting column 3 is placed on which are mounted at least one turntable 1, the console 17 comprising the ball catch 23, as well as at least one, but preferably two supports for front panels 35. Thanks

  to known suitable engagement means, the or each turntable

  nant 1 is mounted on the pivoting column 3 so as to be integral therewith in rotation and so as not to be able to move axially relative to this column 3. The front panel support (s) 35 are maintained exactly aligned above the sector-shaped cutout 61 of or

  each turntable 1 by tightening the screw 39 provided on the flange 37.

  In the re-entrant angle formed by the two ends 45 of the fixing brackets

  tion 43 of the or each support of front panels 35, front panels 57 are fixed, by means of screws, which form the access opening to the cupboard, in which the turntable is located. The two front panels 57 can then be moved in the radial direction with respect to

  the pivoting column 3, until they are exactly in line with

  of the front panels of the neighboring cupboards, and immobilize them in

  their final position by tightening the screw 47 or the nut 49 on the slide

siere 41.

  So that, when the cupboard is closed, the two front panels 57 always remain exactly aligned with the neighboring panels, the console 17 carrying the ball catch 23 is rotated on the

  pivoting column 3 until its axis B passes through the center of the

  11, then immobilized by means of the clamping screw 19. It then matters little that the ball 33 of the ball catch 23 is located or

  not exactly in the middle of the vertical longitudinal extent of the hollow

  he lies. This allows simple mounting, regardless of any differences.

  tolerance or possible imprecision sizing of the cupboard used to house the turntable device. The distance from the axis A of the pivoting column 3 to the latching plate 9 is therefore not influenced by inaccuracies in the dimensioning or mounting of the cupboard.
