Definitions

  • the invention relates to a rotary and pull-out fitting for a shelf in a corner cabinet, with a support held in the corner cabinet so that it can rotate about a vertical axis, a pivot bearing for rotatably mounting the shelf on the support, and a pull-out guide on which the shelf can be moved relative to the support is.
  • Such a pull-out fitting is described in EP 2 253 244 B1.
  • the fitting is intended in particular for corner kitchen cabinets where only one half of the front is accessible through a door, while the other half of the front is adjusted by another body element.
  • the pull-out guide is arranged there on an intermediate carrier, which is supported on the carrier via the pivot bearing. If the shelf is to be pulled out, the entire structure made up of carrier, intermediate carrier and shelf is first pivoted about the axis of the carrier. After an initial phase of this If movement occurs, a coupling mechanism forces an additional rotation of the intermediate carrier relative to the carrier by means of a forced guidance acting between the body and the intermediate carrier. In the final phase of the movement, the shelf can then be pulled out of the door opening relative to the intermediate support.
  • the shelf is guided not only relative to the intermediate support but also relative to the support in such a way that it can be brought into a position in which it protrudes relatively far out of the door opening and is therefore easily accessible and that the shelf has the largest possible footprint and thus makes good use of the available space in the corner cabinet without hitting the carcass of the corner cabinet when swiveling and extending.
  • the object of the invention is to enable a simple height adjustment of the upper shelf.
  • this object is achieved in that the carrier is rotatably mounted on a console which is guided in a rotationally fixed and axially displaceable manner on an axle tube rigidly mounted in the corner cabinet and can be self-lockingly fixed to the axle tube by means of a clamping lever. If the clamping lever is released by hand, the console can be moved to the desired height on the axle tube. Since the entire unit of support and shelf is held on the console, the height of the shelf can be adjusted. When the clamping lever is in its clamping position, it grips the axle tube with a clamping contour, so that the console and thus also the carrier and the shelf are held in a clamped manner on the axle tube.
  • the weight of the support, the shelf and the objects placed on it exerts a torque on the clamping lever, which has the tendency to pivot the clamping lever further towards its clamping position, so that the clamping force is increased and the entire fitting is self-locking in position is held.
  • the clamping lever is mounted on the underside of the console such that it can be pivoted about a horizontal axis, and one end of the clamping lever forms the clamping contour which acts on the axle tube in the clamping position.
  • the axle tube is preferably a square tube that offers a large contact surface for a straight clamping contour of the clamping lever.
  • the opposite end of the clamping lever preferably protrudes over the edge of the
  • the clamping lever can be elastically biased into the clamping position by a spring, so that the clamping is established automatically as soon as the user releases the clamping lever.
  • Fig. 1 is a schematic plan view of a cabinet body with a
  • FIG. 2 shows the same floor plan as FIG. 1, but with emphasis on other components of the fitting;
  • 3 and 4 show the condition of the fitting after an initial phase of a pivoting movement
  • FIG. 7 shows the fitting when the shelf is fully pulled out
  • FIG. 8 shows a perspective view of a height-adjustable console on which all other parts of the fitting are held
  • Fig. 9 shows a section through the console and a clamping lever in one
  • FIG. 10 shows the console and the clamping lever in a non-clamping position.
  • a body of a kitchen corner cabinet 10 is shown in a horizontal section, with side walls 12, a rear wall 14 and a central post 16, the a door opening 18 is delimited by the right side wall 12, while the left half of the front of the body is adjusted by a further body element, not shown.
  • An approximately semicircular shelf 20 is housed inside the body.
  • the shelf 20 is held in the body in such a way that it can be pivoted out of the door opening 18 and then pulled out further.
  • the fitting 22 comprises a stable, arcuate support 24 which can be pivoted about a vertical axis 26 which is fixed to the body.
  • the axle 26 is arranged on the side of the central post 16 facing away from the door opening and is rotatably mounted on a bracket 28 which in turn is held on an axle tube 29 so that it can be adjusted in height.
  • an intermediate support 30 is supported on the free end of the support 24 and can be pivoted relative to the support 24 about a further vertical axis of a pivot bearing 32 .
  • the intermediate support 30 has an arm 34 at its end closer to the mullion which carries a cam follower 36 at the free end. This curve follower engages in a guide slot 38 which is formed in a bracket 28 of the console.
  • the intermediate carrier 30 carries on its upper side a pair of parallel guide rails 40 (shown in phantom in the drawing), which interact with running rails 42 mounted on the underside of the shelf 20 .
  • guide links 44 are also formed on the underside of the shelf 20 , of which only the left-hand guide link is used in the example shown here.
  • the other guide link is intended for use of the shelf in which the door opening 18 is on the other side of the body.
  • the guide links 44 can, for example, be molded directly onto a shelf that is injection-molded from plastic.
  • an arm 46 extends from the carrier 24 and engages with a cam follower 48 formed at its free end in the guide slot 44 of the shelf.
  • the intermediate carrier 30 is fixed in a rotationally fixed manner on the carrier 24 by the cam follower 36 and the guide link 38, so that the carrier and the intermediate carrier behave like a rigid unit. Since the guide link 44 formed on the shelf runs obliquely to the rails 42 in the area of the cam follower 48 , the shelf 20 is also blocked against displacement along the rails 42 . If the user now wants to pivot the shelf 20 out of the door opening, he grips the edge of the shelf through the door opening with his hand and pulls it forward. The shelf 20 and the fitting 22 pivot as a rigid unit about the axis 26. As can be seen in FIG the cam follower 36 can move in the guide slot 38 during the pivoting movement, while a rotation of the intermediate carrier 30 relative to the carrier 24 continues to be prevented.
  • FIG. 5 shows a somewhat later stage of the movement sequence.
  • the carrier 24 has been pivoted further clockwise about the axis 26 and the intermediate carrier 30 has started its pivoting movement about the axis 32, also clockwise. Due to this pivoting movement relative to the carrier 24, the lower one in FIG. 5 runs
  • Shelf 20 is held by the support 24 at the location of the axis 32, a high load-bearing capacity of the shelf is achieved even in the fully extended position.
  • the cam follower 36 has reached the end of the guide link 38, so that the movement of the intermediate carrier 30 has also come to a standstill.
  • the curve follower 48 seated on the carrier 24 has reached the end of the guide slot 44 after it has passed a straight section of this guide slot running parallel to the running rails 42 . During this phase, only a linear displacement movement of the shelf relative to the intermediate carrier 30 has taken place.
  • the axle tube 29 is designed as a square tube on which a bushing 50 is guided in a rotationally fixed and displaceable manner.
  • the bushing 50 is formed in one piece with the bracket 28, which may be, for example, a plastic injection molded part.
  • the bushing 50 has a square inner cross section which is adapted to the outer cross section of the axle tube 29 .
  • a cylindrical outer surface of the bushing 50 forms a bearing for the carrier 24, not shown here.
  • the console 28 has an approximately L-shaped outline, with a bearing arm 52 on which the bushing 50 is formed, and a control arm 54 in which the guide slot 38 formed as a curved channel is located.
  • a clamping lever 56 is arranged on the underside of the bearing arm 52, of which only one over in FIG the actuating end 58 protruding from the control arm 54 can be seen.
  • the clamping lever 56 is pivotably mounted on an axle pin 60 which extends between two opposing wall sections of a peripheral wall of the console 28 and of which an end protruding from the peripheral wall can be seen in FIG.
  • Fig. 9 shows a longitudinal section through the bearing arm 52 and the clamping lever 56.
  • the clamping lever on the underside of the console extends to the axle tube 29 and forms a blade-like clamping contour 62 there, which extends over the entire width on a side surface of the Square tube 29 is present.
  • This side surface has a horizontal corrugation 63, which is shown in FIG. 9 in an enlarged detail X.
  • the clamping lever forms two projecting tabs 64 on its front and rear edges in FIG. In the drawing, the tabs 64 can only be seen in outline, since they are largely covered by stiffening ribs 66 of the console.
  • the stiffening ribs 66 form an inclined ramp which creates a certain free space for the pivoting of the clamping lever 56 .
  • a spring 70 (helical spring) is held in a spring seat 68, one end of which rests on an upper wall of the console and the other end on the clamping lever 56, so that the clamping lever can be turned clockwise into the position shown in Fig. 9 is prestressed in the position shown, in which the clamping contour 62 is held in engagement with the corrugation 63.
  • the clamping lever 56 forms a recess 72 which cuts out part of the outline of the clamping lever in which one end of the groove-like guide link 38 is located.
  • the bushing 50 is double-walled, with an inner wall 74 that forms the inner cross-section of the bushing and thus the guide contour for the axle tube 29 , and a cylindrical outer wall 76 that forms the bearing for the carrier 24 .
  • the axle tube 29 is surrounded by the inner wall 74 with a small clearance.
  • a force is exerted on the console by the clamping contour 62 of the clamping lever, which is supported on the axle tube 29 exercised, which leads to the fact that the inner wall 74 of the bushing 50 rests snugly against the axle tube on the left-hand side in FIG. In this state, therefore, the bracket and the entire load carried by the bracket is clamped to the axle tube 29.
  • the bracket 24 and shelf are assembled, their weight exerts a downward force on the console.
  • due to friction between the clamping contour 62 and the axle tube 29 an equal and oppositely directed force is generated, which prevents the console and the entire fitting from lowering.
  • Fig. 9 to pivot, whereby the clamping between the clamping contour 62 and the axle tube 29 is reinforced.
  • the corrugation 63 then reliably prevents the bracket 28 from moving downwards.
  • the height of the console 28 can be easily adjusted before the carrier 24 and the shelf are mounted on the console.
  • the axle tube 29 can be telescopic in an upper end section, so that a distance can be temporarily created between the upper end of the axle tube and the upper wall of the body, which allows the carrier 24 to be pushed onto the axle tube from above until it opens the socket 50 is stored. If the height of the shelf is subsequently to be adjusted, the fitting can be temporarily placed in the extended position shown in FIG. The carrier 24 is then in a position in which the actuating end 58 of the clamping lever can be gripped by hand in order to carry out the height adjustment.
