A connecting link (7)on the radial guide (8) is linked to the link arrangement. The guide is connected to damper (D) and to a radially profiled control (6). The linkage arrangement consists either of a four-bar linkage or of a barrel linkage with inter-engaging cylinders.

Description

The invention relates to a corner cabinet with a Fitting with at least one on an upright rotating column rotatable shelf carousel, with from the column outgoing support arms, on which a door fittings double-leaf angled door each with an articulated arrangement is movably mounted, each of which has a connecting link almost radial to the rotating column leading guide is articulated with a Damper and with a radially profiled control element each is in an operative connection via a leadership role, and the column with the support arms, the connecting links, the door fittings and the door panels around the Column and the control member are rotatably mounted.

An older fitting is known from DE 30 49 114 C2 become, in which the joint brackets from rigid to the Cantilever levers fastened to the door wings and articulated on support arms are formed, each with a connecting link articulated attacks, and being the two connecting links in a common fulcrum opposite the control body are movable. Between the links and the A tension spring is attached to each support arm.

A further development of the fitting is the which is described in DE 296 21 698 U1. This points in the quadrilaterals and as a connecting link Flat bars and the sled is made very long and embraces the central in a U-shape Axis. Accordingly, it is radial as a pneumatic cylinder trained damper relatively long and has a variable Damping over its actuation path. This Design features lead to low position stability and uneven running of the door leaves during their swiveling in and swiveling movements as well as when reaching the end position. In addition, the door panels bump and grind when twisted in the swiveled-in state the upper axle bracket.

The object of the invention is one according to the aforementioned Type of fitting for a shelf carousel to improve in that this fitting a precise guidance and stable storage for positionally stable Door leaf turning and moving movement with simplified Has structure.

This object is achieved in that the joint arrangement either from a quadrangle, the Handlebars have a stiffening profile, or from a pot joint with a vertical axis with interlocking There are cylinders and the connecting links each close to the door fitting and in relation to the joint arrangement articulated to the joint of the two door leaves are.

The subclaims contain design features which advantageous and beneficial further training of the task solution represent.

The fitting according to a first embodiment has a four-bar link on, the control lever preferably by beads are stable and relatively long Bear bearing pins that are torsionally rigid in the corresponding socket are held. Contributes to the precision of the guidance continue with a sled to which the connecting link are articulated and which is arranged behind the axis of rotation. On the one hand, these components give the doors a stable structure Bracket and on the other hand ensure a durable and stable twisting of the door leaves and the entire Shelf carousel.

For the retracting and unfolding movement and the retracting and extending movement of the two wings are two as joint brackets articulated quadrilaterally arranged from each two crimped levers with four in the closed position Trapezoidal points provided joint axes, and on a longer one engages the inner lever of each quadrangle Link arm on, on the other hand, the most distant Control carriage is articulated.

This results in a relatively far back control slide due to its short sliding guide for the connecting links and the quadrangle has a high positional stability Basic bracket and ensures optimal movement and Twisting the door panels and the carousel; continues to be the sled with a new type of rotary working equipped with a damping element filled with damping gel, which the speed of the sled in its movement brakes and a muffled striking the door wing on the cabinet side walls and in front of each other guaranteed.

The twisting of the carousels is due to the training facilitated by run-up ramps on the joint parts of the four-bar linkage, through which the door leaves in the closed state raised and lowered when swiveled in are. The support arms are designed as stamped parts and with Insert plates, which the bearing eyes of the handlebars and the run-up ramps as characteristics so that these Parts are easy to manufacture. Besides, they are Insert plates each in different positions on the to arrange corresponding support arm, whereby the respective Favorable handlebar position with different door leaf widths is selectable.

In a second embodiment, the joint arrangement exists each from a support plate to which the door fitting is angled and the drawbar are articulated and with one Pot joint the associated support arm spaced from the drawbar joint is articulated.

The pot joint is adjustable with two horizontally Provide slide guides on which on the one hand the door fitting and on the other hand, the support arm are attached. The Adjustment means of the cross slide enable an exact Alignment of the door horizontally.

The vertically directed pot joint is also advantageous formed with three concentric cylinders, from which the outer with the one adjustment slide and the middle is connected to the second adjustment slide. These two cylinders thus form the coaxial pivot bearing parts the door wing.

The middle cylinder is provided with a guideway, which is axially inclined. A guide pin runs in the guideway, which is on the inner cylinder which with further radial extensions in the axial grooves of the outer Cylinder held in rotation and axially adjustable is. The guideway and the guide pin are thus to each other oriented and trained so that the doors at Opened by rotating the pot joint and lowered be raised when closing. The basic setting in the height is adjusted by a central adjustment screw, which is the axial position of the inner cylinder to the outer sets.

The bearing parts are preferably injection molded from plastic; all cylinders and the sled are simply interlocked or inserted into the guideways. This concentric Bearing arrangement with the adjustment slide eliminates the need for adjustment elements on the door fitting and a cam arrangement on the Bearing plates.

Another version of the guide means is by a Given the lever with a vertical axis on one central mounting plate is articulated with the support arms is firmly connected. The leading role is on the lever rotatably mounted, preferably with the same Longitudinal pin on which the two tie rods are articulated. The leadership role and the central pillar are both almost in line with the impact of the two door leaves; the Lever is spaced laterally.

There is a presettable return spring and a gear slide of a damper arranged. The gear slide has a different one on both sides Entrainment, and the pinion of the rotary Damper is floating so that when Closing the door a higher damping by a firmer Coupling, e.g. by meshing a toothing, is achieved than when opening, for example only frictional coupling occurs.

A door can be fitted with two door fittings 9 before installation provided, whose adjustment slide I1 each in the inner Bearing cylinder Z1 inserted and with the adjustment screw S1 is set. On the other hand, on the support arms the other parts of the pot bearing attached, and then the door with the cylinder Z1 can be opened with a wide open Door position can be hooked in, using the guide pins FS through the axial guideway sections FA in enter the inclined guideway FB.

Due to its relatively large guide surfaces on the inside and outer cylinder surfaces of the bearing cylinders S1 - S3 ensures high stability in all directions. The plastic bearing parts have low friction and practically no wear. They are easy to spray and are a fourfold repeat part.

The door adjustment is due to the adjustability in the upper and in the lower pot bearing in all directions and inclinations very easy to do. The height adjustment in both Pot storage is redundant, but it produces an even one Load distribution on both height guideways FB in the two pot bearings of a door leaf. Are preferred One guide track is offset by 180 ° in each pot bearing arranged. The axial positive guidance of the door at Opening and closing is done by the two flanks the slot-like guideway in connection with the loose the matching pin FS reached.

FIG. 16 shows a further advantageous arrangement of the Rotary guidance to the base ring 6b, not shown here, which corresponds to that in FIG. 5. On the support plate 20 * is off center to the fitting symmetry axis SA as approximate radial guide means articulated a steering lever 8 *, the approximately in the position of the axis of symmetry SA the leading role 2 carries on a vertical axis of rotation, with which too the connecting links 7 are articulated. The executives are thus directly by the connecting link 7 of transfer the door fittings to the guide roller 2 and vice versa. The length of the steering lever section 8 *, the Keisbahn the swivel castor 2 determines, in relation to much less deflection of the same in the guide ring profiling produces an almost radial movement of the Swivel castor 2 in relation to column 1.

A return spring advantageously grips directly on the steering lever 8 * F and a gearbox of a damper D, which as rotary money fighter is trained. The spring F is with a clamping screw SP to a suitable door return force adjustable.

The damper D is equipped with a pinion R on its axis and in a damper insert DE in a damper guide DF kept movable, in addition to a Carriage DS is guided in connection with the steering lever 8 * stands. The damper slide DS is with two opposite differently designed areas FZ, FR provided between which the pinion R is arranged. The a surface FZ is provided with teeth in which the Pinion R engages when the door closes takes place. The damper guide arranged at an angle to the slide DS DF pushes the pinion R into the teeth and pushes it out in reverse motion so that it on the other surface FR or the like a friction surface. is correspondingly inhibited rotates slowly rotating. Only in End region of this friction surface FR, the pinion R at reached almost fully open doors, it hits one Cam N through which the pinion with the damper insert DE pressed back into the teeth on the other side, whereby the full damping effect resumes and the Doors are braked at the end of the opening process. Of course, the asymmetrical damper device also in connection with the slide 8, FIG. 6 deploy.
