Definitions

  • the invention concerns an immobilization device for arresting a furniture part movably supported in or on an article of furniture, in particular a drawer, in a closed end position, comprising at least one locking unit having a receiving element for an engagement element, wherein the receiving element or the engagement element is arranged on the article of furniture and the other element is arranged on the movable furniture part and the two elements are operatively connected at least in the closed end position of the movable furniture part.
  • Such immobilization devices are known per se and serve to be able to adjust the front gap which exists in the closed end position between the inside of the front panel and the front end faces of the walls of the body or carcass of an article of furniture.
  • GB 21 74 139 A discloses a closing device for a door of an article of furniture in which the engagement element is formed by a ball which is arranged on the door and which is caught by a locking unit arranged on the furniture carcass.
  • the ball is fixed on a screwthreaded bar whereby the position of the balls is variable in relation to the depth of the article of furniture, whereby the remaining front gap between the door and the furniture carcass is adjustable. That solution has been found to suffer from the disadvantage of the short displacement travel and inaccurate adjustability of the engagement element.
  • the object of the invention is to provide an immobilization device of the general kind set forth, which on the one hand permits an uncomplicated change in the front gap and which on the other hand has a structurally simple and exact adjustment mechanism.
  • the relative position of the receiving element with respect to the engagement element is linearly variable in the depth of the article of furniture by means of a displacement device adapted to convert a rotary movement into a translatory movement.
  • At least one locking unit includes a slide portion supported linearly movably with respect to a base portion and the receiving element is arranged on said slide portion, wherein it has proven to be advantageous if the displacement device for altering the relative position of the receiving element is of such an arrangement and configuration that it acts directly on the slide portion. In that case it is particularly desirable if the receiving element is arranged rotatably on the linearly movable slide portion.
  • Such an arrangement provides that the two functions—pivotal movement of the receiving element and altering the position of the receiving element in relation to the depth of the article of furniture—are implemented by way of different mechanisms, whereby it is possible to achieve overall an increase in stability and at the same time simplification in structure.
  • the locking unit includes a blocking mechanism for releasably fixing the preferably rotatably supported receiving element in a position of arresting the engagement element.
  • a blocking mechanism for releasably fixing the preferably rotatably supported receiving element in a position of arresting the engagement element.
  • the locking unit has a slide portion supported linearly movably with respect to a base portion
  • the blocking mechanism is of such an arrangement and configuration that it acts between the linearly movable slide portion and the receiving element which is preferably arranged rotatably thereon and the linearly movably supported slide portion has a preferably cardioidal sliding guide track.
  • the displacement device has a rotatably supported actuating element, wherein the axis of rotation of the actuating element extends substantially normal to the main plane of the locking unit.
  • a further embodiment of the invention provides that the actuating element is rotatably supported on the base element of the locking unit in such a way that the actuating element is operatively connected to guide means arranged on the linearly movably supported slide portion, preferably by way of a spiral-shaped sliding guide track.
  • guide means arranged on the linearly movably supported slide portion, preferably by way of a spiral-shaped sliding guide track.
  • a preferred embodiment of the invention provides that the receiving element is arranged on the movable furniture part and the engagement element is arranged stationarily on the article of furniture.
  • the engagement element has a plate-shaped main element having a pin which is provided thereon and whose longitudinal axis extends substantially normal to the main plane of the main element.
  • a particularly space-saving embodiment of the invention further provides that the engagement element is arranged stationarily on the carcass rail of a guide system for a drawer forming the movable furniture part. In that case it has been found particularly desirable if the at least one locking unit is arranged on the drawer underside. If the immobilization device is arranged in the region of the front of the article of furniture in the closed end position of the movable furniture part, that provides for particularly convenient and comfortable accessibility to the immobilization device for the fitter or a user.
  • a preferred embodiment of the invention further provides that the immobilization device has at least two locking units which are operatively connected together by way of a synchronization mechanism, wherein the synchronization mechanism has at least two coupling elements respectively associated with different locking units and at least one synchronization unit and the coupling elements are motionally coupled by means of the synchronization unit.
  • Such a configuration ensures that locking of the receiving elements with the engagement elements substantially simultaneously unlocks the two locking units on both sides of the movable furniture part independently of the position at which the user exerts the force on the front panel in the closing direction of the movable furniture part, that is to say irrespective of whether the user presses against the front panel at the right or the left or in the center or at the right or the left, by virtue of the coupling effect.
  • the synchronization unit has a stationarily arranged base element on which a synchronization element is rotatably movably supported, wherein in accordance with a first variant the synchronization element is formed by a gear and the synchronization unit has two racks which are mounted movably with a translatory movement on the base element and which are in engagement on opposite sides with the synchronization element and are or can be respectively connected in an end portion to a coupling element.
  • synchronization element could be formed for example by a double-armed lever.
  • a further embodiment of the invention provides that at least one locking unit has an overload safety mechanism including at least two parts which are movably connected together.
  • the overload safety mechanism has two parts which are rotatably movably connected to each other and which are pivotable between a first end position and a second end position, and between which a holding device is operative for releasably holding or for returning the parts which are rotatably connected together in or into the first end position.
  • the receiving element has a base element and a locking element movably connected to the base element, wherein the blocking mechanism acts on the base element, it has proven desirable if the at least two movably interconnected parts of the overload safety mechanism are formed by the base element and by the locking element of the receiving element, thereby providing a structurally simple solution.
  • each locking unit includes a blocking mechanism and/or an overload safety mechanism.
  • the invention further concerns a lockable ejector device for a furniture part supported movably in or on an article of furniture, comprising an ejector element acted upon by a force storage means, and an immobilization device.
  • Such a lockable ejector device permits opening of a handle-less movable furniture part at least to such an extent that it is possible to grip behind the front panel and to open the movable furniture part even without the presence of a handle fitment.
  • unlocking of the ejector device can be effected for example by way of a button or in the case of so-called touch-latch fitments by exerting a pressure on the front panel in the closing direction of the movable furniture part.
  • locking of the ejector device is effected by means of the blocking mechanism for the receiving element.
  • the ejector device or the ejector element is arranged on the locking unit.
  • the ejector device or the ejector element is arranged separately from the immobilization device on the movable furniture part, in which respect it has proven to be desirable if the ejector device or the ejector element is arranged in the guide system for a drawer forming the movable furniture part, preferably on the carcass rail.

  • the movable furniture part 2 is disposed in its closed end position E so that the locking element 44 arrests the pin 15 of the engagement element 8 .
  • the holding device 33 opens due to the force that the pin 15 exerts on the locking element 44 , in other words the positively locking connection between the parts 50 and 51 is released and the movable furniture part 2 can be moved into an open position without the receiving element 7 being damaged.
  • FIGS. 23 a through 24 b of a receiving element 7 with a blocking mechanism 32 operates in a similar manner to the embodiment shown in FIGS. 21 a through 22 b.
  • the embodiment of FIGS. 23 a through 24 b differs from the embodiment of FIGS. 21 a through 22 b in the nature of the two parts 50 , 51 of the holding device 33 .
  • the two parts 50 and 51 of the holding device 33 are formed by two magnets which exert an attracting action on each other.
  • FIGS. 25 through 28 A very similar embodiment is shown in FIGS. 25 through 28 .
  • this embodiment differs in the nature of the two parts 50 , 51 of the holding device 33 , wherein the first part 50 of the holding device 33 is formed by a magnet while the second part 51 of the holding device 33 is formed by a metallic counterpart pole in the form of a loop arranged supported by way of two springs 52 on the base element 43 of the receiving element 7 .
  • This configuration has the advantage that the separation force between the two parts 50 , 51 of the holding device 33 is increased as—as can be seen in particular from FIGS. 26 a and 27 —when a separation force is operative between the two parts 50 , 51 , that firstly involves an inclined positioning of the part 51 of the holding device 33 before the part 50 actually separates by breaking away.
  • the operative force of the ejector device can be increased and on the other hand a rebound of the movable furniture part 2 upon closure can be at least partially absorbed by means of the holding device 33 .
  • FIGS. 29 a through 29 d describe different positions of the receiving element 7 of the locking unit 6 in the embodiment of FIG. 20 a during a normal opening process.
  • normal opening process is used to denote release of the locking action by pressing the movable furniture part 2 inwardly into a position behind the closed end position E, by the user.
  • the movement of the movable furniture part 2 into the release position provides that the blocking mechanism 31 formed by a sliding guide track 45 is released whereby the base element 43 is pivoted so that the pin 15 of the engagement element 8 is released by the locking element 44 ( FIG. 29 c ) and the movable furniture part 2 is displaced by means of the ejector device into an open position as shown in FIG. 29 c.
  • FIGS. 30 a through 30 g show different positions of the receiving element 7 of the locking unit 6 of the embodiment of FIG. 20 a in the case of incorrect operation by a user.
  • incorrect operation is used to mean that the user pulls the movable furniture part 2 out of the furniture carcass 4 without previously releasing the locking action in respect of the engagement element 8 by the receiving element 7 by pushing in the movable furniture part 2 .
  • FIG. 30 a again shows the starting position in which the movable furniture part 2 is in its closed end position E. If now as shown in FIG. 30 b the movable furniture part 2 is pulled directly in the opening direction OR the locking element 44 of the receiving element 7 , by virtue of its contact with the pin 15 of the locking element 8 , is rotated or pivoted about the axis of rotation e, more specifically against the force of the holding device 33 which in this embodiment is formed by a tension spring.
  • the movable furniture part 2 is moved in the closing direction SR into the furniture carcass 4 the locking element 44 moves onto the pin 15 and, in a further inward movement of the movable furniture part 2 , the receiving element 7 is pivoted as shown in FIG. 30 f whereby the blocking mechanism 31 is released and the base element 43 is pivoted by virtue of the spring 46 being relieved of stress, into a position of releasing the pin 15 , whereby the movable furniture part 2 is once again displaced into an open position ( FIG. 30 g ) by the ejector device 18 , the force storage means 19 of which was at least partially loaded by the inward movement of the movable furniture part 2 .
  • the open position in FIG. 30 g after incorrect operation by the user therefore corresponds to the open position of FIG. 29 d after a normal opening process. That means in other words that, in the event of incorrect operation by the user, in a first step the overload safety mechanism 32 comes into effect whereby the movable furniture part 2 —although the locking unit 6 has not been unlocked—can be opened without parts of the locking unit 6 , in particular the receiving element 7 , being damaged before in a second step the movable furniture part 2 is moved in the closing direction SR again into the furniture carcass 4 .
  • immobilization devices for arresting a movable furniture part and lockable ejector devices for a movable furniture part are not to be interpreted in a restrictive sense but in fact are only individual examples of numerous possible ways of implementing the concept of the invention of an immobilization device or a lockable ejector device for a movable furniture part.
