Definitions

  • the invention relates to a piece of furniture with a furniture body, a furniture part mounted so as to be movable relative to the furniture body and with a furniture drive of the type to be described for moving the movable furniture part.
  • the support of such furniture drives is usually fastened in or to a side wall of the furniture body, wherein the actuating arm arrangement of the furniture drive is prestressed by at least one spring device and is connected to the movable furniture part in an assembled state.
  • a rotatable tool holder is provided at a front end area of the housing of the furniture drive, wherein a spindle nut mounted on a spindle can be moved along the spindle by rotating the tool holder using a tool.
  • a spring assembly is supported on the spindle nut, wherein a force of the spring assembly acting on the actuating arm arrangement can be adjusted by the adjustable mounting of the spindle nut along the spindle.
  • the spindle is arranged fixedly in relation to the housing of the furniture drive.
  • the object of the present invention is to provide a furniture drive of the type mentioned at the outset, wherein at least one of the disadvantages discussed above is avoided.
  • the angle which the axis of rotation of the adjusting element and the longitudinal direction of the threaded portion enclose with respect to one another can be changed during a movement of the at least one adjusting arm.
  • the adjustment element and the rotatable threaded section are mounted relative to each other in an angularly movable manner when the adjusting arm moves, so that the adjustment device for adjusting a force of the spring device and the adjusting arm arrangement can assume different positions relative to each other.
  • the components of the furniture drive can therefore be nested into each other and consequently arranged closer to each other. In this way, the furniture drive can be built more compactly, the adjustment range of the spring device on the threaded section can be increased and higher performance ranges of the furniture drive can be covered.
  • a further advantage of the invention is that the arrangement of the adjustment element on the furniture drive is not fixed, but can be adjusted during the manufacture of the Furniture drive - depending on the type and area of application - can be positioned at various desired positions.
  • the adjustment element of the adjustment device faces the movable furniture part in an assembled state of the furniture drive and is arranged in a front area of the carrier.
  • This can significantly improve accessibility to the adjustment element.
  • the carrier of the furniture drive is designed to be accommodated at least partially, preferably essentially completely, within the furniture panel in an assembled state on the furniture panel.
  • the adjustment element can only be accessed from the side by drilling holes in the furniture panel, which weakens the furniture panel, is often perceived as visually unsightly and means additional assembly work. For this reason, accessibility of the adjustment element from a front end face of the carrier is definitely advantageous.
  • the furniture drive has at least one angularly movable coupling device for transmitting a rotational movement of the adjusting element into a rotational movement of the threaded section.
  • the angularly movable coupling device can have at least one elastic member, preferably a bellows, a rubber molded element or a coil spring coupling, and/or at least one gear, preferably a bevel gear, and/or a joint, preferably a universal joint or cardan joint.
  • the furniture drive can have at least one shaft that can be driven by the adjusting element for driving the threaded section, wherein the at least one shaft is mounted in or along a guide, preferably a slot, so that it can move relative to the carrier.
  • a guide preferably a slot
  • the adjustment element of the adjustment device can have a receiving device for a tool, preferably a screwdriver, wherein the adjustment element can be driven by exerting a torque on the receiving device by means of the tool.
  • the receiving device can, for example, have a Phillips shape (for example a Pozidriv profile), a square profile, a hexagon profile or a hexagon (for example a Torx profile).
  • the support of the furniture drive can be designed as a mounting plate or as a housing, in particular a cuboid-shaped housing.
  • the support can be designed to be essentially rectangular, wherein it is preferably provided that the ratio of a length of the support to a height of the support is greater than 1 to 0.7, preferably greater than 1 to 0.5. By dimensioning the support in this way, a reduced height of the furniture drive can be achieved.
  • the furniture according to the invention has a furniture body, a furniture part mounted so as to be movable relative to the furniture body and at least one furniture drive of the type in question. It can be provided that the furniture body has a furniture plate, preferably running horizontally or vertically, for fastening the carrier, wherein the carrier of the furniture drive is accommodated at least in regions, preferably essentially completely, within the furniture plate of the furniture body.
  • Fig. 1a shows a perspective view of a piece of furniture 1, which has a furniture body 2, a furniture part 3 that is movably mounted relative to the furniture body 2, and at least one furniture drive 4 for moving the movable furniture part 3.
  • the furniture 1 has furniture panels 6 in the form of side walls, an upper floor 7 and a lower floor 8.
  • the furniture drive 4 is at least partially, preferably essentially completely, integrated in the side wall designed as furniture panels 6, wherein the movable furniture part 3 is movably mounted between a closed position that covers the furniture body 2 and an open position that is raised relative to the furniture body 2.
  • the furniture drive 4 in a horizontally running furniture panel, for example in the upper floor 7, in the lower floor 8 and/or in a shelf arranged between the upper floor 7 and the lower floor 8.

  • the furniture drives 4 each have a carrier 9 to be attached to the furniture body 2.
  • the carrier 9 is accommodated in an assembled state at least partially, preferably essentially completely, within a recess 11 of the side walls designed as furniture panels 6. In an assembled state, the carrier 9 can be essentially flush with an end face 6a of the furniture panel 6.
  • the recess 11 is designed, for example, as a blind hole, whereby the carrier 9 can be inserted into the pocket-shaped recess 11 of the furniture panel 6 from the front during assembly (ie starting from the narrow front side 6a of the furniture panel 6).
  • At least one spring device 10 for applying force to the actuating arm arrangement 5 is arranged in or on the carrier 9.
  • a cover 12 is provided at the front end region of the carrier 9, whereby at least one movably mounted actuating arm 5a, 5b, 5c, 5d, 5e ( Fig. 2a ) of the actuating arm arrangement 5 can be guided through the cover 12 in a relative position.

  • a second end region of the spring device 10 acts on a pressure piece 20, which is articulated via an adjustable engagement point 18 to an intermediate lever 16 pivotable about a preferably fixed joint axis 15.
  • a force of the spring device 10 on the actuating arm arrangement 5 can be adjusted by means of an adjustment device 19.
  • the adjustment device 19 comprises an adjustment element 19a that can be rotated about an axis of rotation (R), wherein a position of the engagement point 18 along a threaded section 17 can be adjusted by rotating the adjustment element 19a about the axis of rotation (R).
  • the threaded section 17 has a longitudinal direction (L). The angle that the longitudinal direction (L) of the threaded section 17 and the axis of rotation (R) of the adjustment element 19a form with respect to one another can be changed when the actuating arm arrangement 5 moves.
  • a rotational movement of the adjustment element 19a can be transferred to the threaded section 17, so that the threaded section 17 is set in a rotational movement and the engagement point 18 is thereby moved along the threaded section 17.
  • the adjusting element 19a of the adjusting device 19 faces the movable furniture part 3 in an assembled state of the furniture drive 4 and is arranged in a front region of the carrier 9. In this The adjusting element 19a can be conveniently operated from the front using a tool.
  • At least one shaft 28 that can be driven by the adjusting element 19a is provided for driving the threaded section 17, wherein the at least one shaft 28 is mounted in or along a guide 30, preferably an elongated hole, so that it can move relative to the carrier 9.
  • the shaft 28 is arranged in or on a shaft bearing 29, wherein the guide 30 is arranged on the shaft bearing 29 and a pin 32 that is fixedly mounted on the carrier 9 engages in the guide 30, which is preferably linear.
  • the shaft bearing 29 is displaceable relative to the fixed pin 32.
  • the actuating arm arrangement 5 comprises at least one, preferably several, actuating arm(s) 5a, 5b, 5c, 5d, 5e for moving the movable furniture part 3.
  • a fitting part 21 is to be fastened to the movable furniture part 3, wherein the fitting part 21 has at least one or more fastening points 22 and can be releasably locked to an actuating arm 5e of the actuating arm arrangement 5.
  • the locked state between the actuating arm 5e and the fitting part 21 is shown.
  • a cover 12 is provided which has at least one laterally projecting flange 12a.
  • the flange 12a is essentially ring-shaped and forms a depth stop for the carrier 9 which can be placed on an end face 6a of the furniture panel 6.
  • Fig. 2b shows the furniture drive 4 according to Fig. 2a , wherein the carrier 9 is closed by a second housing wall 9b.
  • the first housing wall 9a and the second housing wall 9b are each flat and together form a substantially cuboid-shaped carrier 9.
  • the housing walls 9a, 9b are spaced parallel to one another, wherein a front opening 23 is formed between the housing walls 9a, 9b, wherein the cover 12 in the region of this opening 23 is arranged and allows the passage of a tool for actuating the adjusting device 19.
  • Fig. 3a shows the furniture drive 4 with the carrier 9 in a side view.
  • the threaded section 17 is arranged on an intermediate lever 16, which is pivotally mounted about a joint axis 15 arranged in a fixed position on the carrier 9.
  • the spring device 10 exerts a minimal torque on the actuating arm arrangement 5, because the point of attack 18 of the spring device 10 is located in an area adjacent to the joint axis 15 of the intermediate lever 16.
  • An imaginary connecting line between the joint axis 15 of the intermediate lever 16 and the point of attack 18 of the spring device 10 forms a relatively short lever arm, whereby a minimal torque acts on the actuating arm arrangement 5.
  • the axis of rotation (R) of the adjusting element 19a of the adjusting device 19 and the longitudinal direction (L) of the threaded section 17 enclose an angle with each other, which can be changed when the actuating arm arrangement 5 moves.
  • the advantage of the invention is based on the Fig. 3a This can be clearly seen because in the closed position of the furniture drive 4 shown - due to the angularly movable mounting of the axis of rotation (R) and the longitudinal direction (L) - the actuating arms 5a-5e of the actuating arm arrangement 5 together with the spring device 10 and the adjusting device 19 assume a very compact position relative to one another.
  • the carrier 9 can be essentially rectangular, wherein it is preferably provided that the ratio of a length (L1) of the carrier 9 to a height (H1) of the carrier 9 is greater than 1 to 0.7, preferably greater than 1 to 0.5. By means of such dimensioning, a reduced height (H1) of the carrier 9 can be achieved. As a result, the height of the recess 11 ( Fig. 1b ) of the furniture panels 6 can be dimensioned small, whereby the manufacturing effort of the recess 11 and the weakening of the furniture panel 6 are minimal.
  • Fig. 3b shows the furniture drive 4 according to Fig. 3a with the minimum force setting of the spring device 10, whereby the actuating arm arrangement 5 with the actuating arms 5a-5e is in an open position. It can be seen that the angle which the rotation axis (R) of the adjusting element 9 and the longitudinal direction (L) of the threaded section 17 to each other, with respect to the Fig. 3a shown closed position has been reduced.
  • the actuating arm arrangement 5 has a first actuating arm 5a that can pivot about a first joint axis 26 and at least one second actuating arm 5b that is mounted so that it can pivot about a second joint axis 27.
  • the first joint axis 26 and the second joint axis 27 are spaced apart from one another in a longitudinal direction (L2) of the carrier 9, with the second joint axis 27 being arranged in a front region of the carrier 9 in relation to the first joint axis 26.
  • the intermediate lever 16 is directly connected to the second (front) actuating arm 5b via a preferably arcuately designed push lever 24.
  • the first actuating arm 5a is therefore not directly connected to the push lever 24 via a joint axis, but is instead guided so that it can move within the push lever 24. This is evident from Fig. 2a This allows an improved and direct introduction of force from the spring device 10 into the actuating arm arrangement 5.
  • Fig. 4a shows the furniture drive 4 according to the embodiment of the Fig. 3a and Fig. 3b .
  • the spring device 10 now exerts a maximum torque on the actuating arm arrangement 5 because the point of attack 18 of the spring device 10 has been moved by a rotation of the adjusting element 19a about the axis of rotation (R) into a position remote from the joint axis 15 of the intermediate lever 16.
  • An imaginary connecting line between the joint axis 15 of the intermediate lever 16 and the point of attack 18 of the spring device 10 now forms a Fig. 3a, 3b longer lever arm, whereby the spring device 10 exerts a maximum torque on the actuating arm arrangement 5.
  • Fig. 4b shows the furniture drive 4 according to Fig. 4a in an open position of the actuating arm arrangement 5, wherein a maximum torque is exerted on the actuating arm arrangement 5 by the spring device 10.
  • the axis of rotation (R) of the adjusting element 19a and the longitudinal direction (L) of the threaded section 17 enclose an angle to one another, which can be changed by the presence of the angularly movable coupling device 25 and by a movement of the actuating arm arrangement 5.
  • Fig.5 shows the furniture drive 4 in an exploded view.
  • the carrier 9 has two housing walls 9a, 9b that are spaced parallel from one another, between which the spring device 10 and the actuating arm arrangement 5 with the actuating arms 5a-5e are accommodated.
  • the adjustment device 19 for adjusting a torque acting on the actuating arm arrangement 5 has an adjustment element 19a that can be rotated about the axis of rotation (R) and drives the threaded section 17 for the adjustable mounting of the engagement point 18 via the shaft 28.

  • the shaft 28 can be driven by rotating the adjusting element 19a about the axis of rotation (R), whereby the shaft 28 drives the threaded section 17 about the longitudinal direction (L) via the toothing 31b and the engagement point 18 of the spring device 10 is moved along the threaded section 17.
  • the threaded section 17 is arranged on the intermediate lever 16, which is mounted on the carrier 9 so that it can pivot about the joint axis 15.
  • the guide 30 of the shaft bearing 29 can compensate for compensating movements caused by the angle-dependent coupling device 25.
  • Fig. 6b shows the furniture drive 4 in a cross section, which in an assembled state is essentially completely accommodated within the recess 11 of the furniture panel 6.
  • the furniture drive 4 can have at least one damping device 33, for example a piston-cylinder unit, for damping a movement of the actuating arm arrangement 5.
  • a movement of the actuating arm arrangement 5 during the closing movement can be controlled via a rocker arm 34 pivotable about a joint axis 35. into the damping device 33.
  • the push lever 24 strikes the rocker arm 34 during the closing movement of the actuating arm arrangement 5, wherein a closing movement of the actuating arm arrangement 5 (and thus a closing movement of the movable furniture part 3) can be braked by a relative movement of the piston-cylinder unit.
