Definitions

  • the invention relates to a self-retracting device for a furniture part that can be pulled out of a furniture body by means of a pull-out guide, comprising a base body and a carriage that is movably mounted on the base body and can be slid against the force of a pull-in spring from a basic position into a waiting position in a pull-out direction in which it is held by a holding device, a driver being able to be coupled to the carriage in order to move the carriage from the basic position into the waiting position and being decoupled from the carriage when the carriage is in the waiting position.
  • Self-retracting devices of this type are known. These are usually integrated in pull-out guides. For example, from the WO 2008/119091 A1 a self-retracting device of this type.
  • a disadvantage of such self-retracting devices is that the elongation of the retraction spring changes over the retraction distance, with the result that the force acting at the end of the retraction distance when the carriage is in the area of its basic position is significantly lower than that in the Waiting position of the carriage Force acting on it when the driver couples to or decouples from the carriage. The operator perceives the highest force that he has to actuate as relevant for the ease of use. This highest force occurs when the carriage is in the waiting position (i.e. shortly before the driver is uncoupled when it is pulled out).
  • the force acting on the carriage in its basic position is relevant for the reliable locking of the closed drawer, which is the lowest force in the displacement path of the carriage in such systems.
  • the operator is therefore forced to apply a significantly greater force to open the drawer than is required to reliably keep the drawer closed.
  • the WO 2008/119091 A1 uses a retraction spring that is as long as possible, which is deflected by a total of 180° around deflection rollers to reduce the required overall length.
  • a deflection leads, among other things, to increased stress on the draw-in spring.
  • constant force springs also called constant force springs
  • constant force springs require a relatively large amount of space and have a comparatively short service life.
  • WO 2013/138826 A1 discloses a closing device in which the driver does not interact with a displaceable carriage but with a closing lever which can be pivoted about a pivot axis and which is acted upon by the draw-in spring.
  • the course of the force can be adjusted in this way that the closing force has the highest value in the vicinity of the closed state of the pull-out furniture part.
  • the installation space required for this self-retracting device is relatively large and the retraction path over which the self-retracting device acts is comparatively small in comparison to self-retracting devices which use carriages.
  • Another closing device in which the driver interacts with a pivotable closing lever, is from DE 10 2011 051 907 A1 out.
  • the draw-in spring does not act directly on the closing lever, but rather on another pivoted lever, with the connection between the closing lever and the further lever being pivotable on the closing lever and attached to the other lever connection arm. In this way, the course of the force can be adjusted.
  • the disadvantage here is again the space required and the relatively short pull-in distance.
  • the object of the invention is to provide an advantageous self-retracting device of the type mentioned at the outset, in which an advantageous force curve of the retraction force acting on the driver can be achieved with a relatively large retraction distance and a relatively small installation space required. According to the invention, this is achieved by a self-retracting device with the features of claim 1.
  • the retracting spring acts on a lever which is pivotably mounted about a first pivot axis on the base body, from which the carriage is movably mounted, and which is pivotally mounted on the carriage about a second pivot axis.
  • the lever can be displaced relative to the first pivot axis or the first pivot axis can be displaced relative to the base body.
  • the lever in that pivoting position of the lever about the first pivot axis, which the lever assumes in the basic position of the carriage, the lever can be displaced relative to the first pivot axis or the first pivot axis can be displaced relative to the base body in a direction that Angle of at most 85°, preferably of at most 80°, with the pull-out direction.
  • a reduction in the force exerted by the draw-in spring on the carriage caused by the lever can be reduced in the area of the basic position of the carriage, so that the force acting on the carriage in the area of the basic position of the carriage is increased compared to a conventional design of the self-retracting device, such as in the character description will be explained in more detail.
  • an at least approximately constant force acting on the carriage can be achieved at least over the majority of the drawing-in distance, despite the different elongation of the drawing-in spring.
  • the first pivot axis can advantageously be formed by an axle bolt attached to the base body, which is slidably mounted in a link of the lever, or by an axle bolt attached to the lever, which is slidably mounted in a link of the base body.
  • this connecting link of the lever or the base body is at an angle to the extension direction, at least in a section in which the axle bolt is located, ie it encloses an angle unequal to 90° with the extension direction.
  • This angle is suitably in the range from 50° to 85°, preferably in the range from 65° to 80°.
  • the connecting link of the lever or of the base body can be designed with a curved course. This enables a further adjustment of the spring force acting on the carriage.
  • the draw-in spring acts on the lever in the area between the first and the second pivot axis.
  • the lever on which the draw-in spring acts is therefore a one-armed lever. This contributes to the saving of installation space.
  • the carriage is preferably coupled to the driver via a tilting part arranged on the carriage so that it can tilt about a tilting axis.
  • the driver In a holding position of the tilting part, the driver is held in an intermediate space of the tilting part.
  • the pivoting of the tilting part about the tilting axis can in particular by means of a Guide pin, which engages in a tilting part guide link of the base body of the self-retracting device, be controlled.
  • a Guide pin which engages in a tilting part guide link of the base body of the self-retracting device.
  • the holding device for holding the carriage in the waiting position when the driver is uncoupled can also be designed.
  • a holding device could hold the carriage in its waiting position by magnetic force.
  • the self-retracting device is advantageously integrated into a pull-out guide.
  • the base body is advantageously arranged on the body rail and the driver on the pull-out rail.
  • a first embodiment of the invention is in detail in the Figures 1-29 shown.
  • the 30-32 show the functional principle in a simplified and schematic manner.
  • the 30-32 is a self-retracting device with a base body 1 and one mounted on the base body 1 so as to be displaceable parallel to the pull-out direction 12 Slide 2 shown schematically.
  • the carriage 2 can be moved over a displacement path from a basic position to a waiting position.
  • the carriage 2 in the basic position, in which it is acted upon by a draw-in spring 3.
  • the carriage 2 is coupled to a driver 4, specifically in the exemplary embodiment via a tilting part 5, which is in a holding position when the carriage 2 is in the basic position.
  • the base body 1 is usually rigidly connected to the furniture body and the driver 4 is rigidly connected to the pull-out furniture part, with a reverse arrangement also being possible.
  • the base body 1 can be attached to a body rail of a pull-out guide, the body rail being attached to the furniture body and the pull-out guide also having a pull-out rail attached to the pull-out furniture part.
  • the driver 4 can advantageously be arranged on the pull-out rail.
  • a lever 6 is mounted on the base body 1 such that it can pivot about a first pivot axis 7 .
  • the lever 6 is mounted on the carriage 2 such that it can pivot about a second pivot axis 8 .
  • the draw-in spring 3 acts on this lever 6, in the exemplary embodiment in the region between the first and the second pivot axis 7, 8.
  • the force F exerted by the draw-in spring 3 is thus transmitted to the carriage 2 via the lever 6 .
  • the first lever arm s 1 which acts between the point of application of the retraction spring 3 and the first pivot axis 7 , is also shown, as is the second lever arm s 2 , via which the force F exerted by the retraction spring 3 is transmitted to the carriage 2 .
  • the first lever arm s 1 is the normal distance between the point of action of the draw-in spring 3 on the lever 6 and a straight line 9 which runs parallel to the force F through the first pivot axis 7 .
  • the second lever arm s 2 is the normal distance between the second pivot axis 8 and the straight line 9.
  • the force F exerted by the draw-in spring 3 on the carriage 2 is thus caused by the Lever 6 stocky, ie transferred to the carriage 2 in the ratio s 1 / s 2 .
  • the exemplary embodiment is a one-armed lever.
  • the lever 6 can be displaced relative to the first pivot axis 7 .
  • an axle bolt 10 fixed to the base body 1 is provided in the exemplary embodiment, which is slidably mounted in a connecting link 11 of the lever 6 .
  • link 11 is formed by a slot in lever 6 .
  • link 11 could also be formed by an undercut groove, into which a head of axle bolt 10 engages.
  • the driver 4 When the pull-out furniture part is pulled out from a pushed-in state, the driver 4 is pushed in a pull-out direction 12, moving the carriage 2 starting from the basic position of the carriage 2 ( 30 ) in the pull-out direction 12, against the force exerted by the draw-in spring 3 on the carriage 2.
  • 31 an intermediate position of the carriage 2 between the home position of the carriage 2 and the waiting position of the carriage 2 is shown.
  • the carriage 2 takes the waiting position.
  • the driver 4 can decouple from the carriage 2 in this waiting position.
  • the tilting part 5 is pivoted relative to the carriage 2 about a tilting axis 13 with respect to a holding position, which the tilting part 5 assumes in the basic position of the carriage 2, into a release position. In the release position of the tilting part 5, the driver 4 can move out of a recess 14 of the tilting part 5, in which it is held in the holding position of the tilting part 5.
  • the carriage 2 is held in the waiting position by a holding device, as is known.
  • the holding device can be formed by a guide for the tilting part be, as is further below using the Figures 1-29 is explained.
  • a holding device could also be effected, for example, by magnetic force, with a magnet being able to be arranged on the base body 1 and/or carriage 2 .
  • the driver 4 moves into the recess of the tilting part 5 and pivots it back into the holding position.
  • the retracting driver e.g. by releasing the magnet holder by the retracting driver
  • the holding device is released and the carriage 2 is pulled in by the draw-in spring 3 to the basic position, entraining the driver 4 and thus the pull-out furniture part.
  • the link 11 In the basic position of the carriage 2 and the corresponding position of the lever 6, the link 11 is at an angle to the extension direction 12, the center line of the link (which runs in the direction of the longitudinal extent of the link) therefore has an angle 16 that is not equal to 90° with respect to the extension direction 12.
  • the lever 6 In the position that it occupies in the basic position of the carriage 2, the lever 6 can be displaced relative to the axle bolt 10, i.e. relative to the first pivot axis 7, in a direction 15 which encloses an angle 16 other than 90° with the extension direction 12 .
  • the angle 16 is preferably at most 85° and at least 50°, particularly preferably the angle 16 is at most 80° and at least 65°.
  • the force F exerted by the draw-in spring 3 on the lever 6 is smaller in the basic position of the carriage 2, in which the draw-in spring 3 is less tensioned, than in the waiting position of the carriage 2 2 transmitted force of the retraction spring 3 but raised.
  • the first section a ends at in 31 shown intermediate position, in which the line connecting the first pivot axis 7 with the second pivot axis 8 is perpendicular to the pull-out direction 12.
  • the lever 6 is displaced in relation to the first pivot axis 7 in an opposite direction, which encloses an angle greater than 90° with the extension direction 12.
  • the intermediate position of the carriage 2 is in the range of 30% to 80% of the entire displacement path of the carriage 2.
  • the value of the ratio s 1 / s 2 also increases, ie the gear reduction is reduced.
  • the gear reduction is increased in that the lever 6 is displaced in a direction 15 which encloses an angle greater than 90° with the extension direction 12, ie has a component opposite to the movement in the extension direction, cf. 32 .
  • an increase in the pull-in force of the carriage can be achieved over the last section of the displacement path of the carriage towards the waiting position of the carriage.
  • the force exerted by the draw-in spring 3 acting on the carriage 2 in the basic position can thus be increased.
  • the force acting on the carriage 2 by the draw-in spring 3 can also be greater in the basic position than in a middle region of the displacement path of the carriage.
  • link 11 In the 30-32 the course of the link 11 is shown in a straight line.
  • a curved configuration of link 11 allows the course of the force acting on slide 2 over the displacement path to be further modified in order to achieve a desired force course.
  • the link 11 can be bent in such a way that its center line is concave as seen from the point of application of the draw-in spring on the base body 1 .
  • the pull-out guide comprises a carcass rail 19 that can be fastened to a furniture carcass 17, a pull-out rail 20 that can be fastened to an extendable furniture part 18, and a center rail 21 that is arranged between the carcass rail 19 and the pull-out rail 20.
  • the sliding guidance of the rails 19-21 takes place in the exemplary embodiment shown via rollers 22.
  • these rollers 22 are all arranged on the central rail 21, as a result of which a differential pull-out guide is formed here.
  • a pull-out guide in which a self-retracting device according to the invention is integrated could also be designed in a different way, for example having rolling bodies mounted in cages for mutually displaceable mounting of the rails or also be designed without middle rail(s).
  • the pull-out furniture part 18 can be a drawer, for example.
  • the pull-out furniture part 18 and the furniture body 17 are only in 4 indicated schematically by dashed lines.
  • the base body 1 of the self-retracting device is fixed to the body rail, specifically in the area of the rear end of the body rail in relation to the pull-out direction 12 .
  • the carriage 2 is mounted on the base body 1 so that it can be displaced parallel to the extension direction 12, namely between the basic position (cf. 10 , 13 , 15, 18 , 21 , 25 ) and the waiting position (cf. 12 , 17 , 20 , 23 and 27 ).
  • the tilting part 5 is mounted on the carriage 2 such that it can pivot about the tilting axis 13 . In the basic position of the carriage 2, the tilting part 5 assumes a holding position with respect to its pivoting about the tilting axis 13, and in the waiting position of the carriage 2 it assumes a release position.
  • the pivoting of the tilting part 5 when the carriage 2 is moved from the basic position to the waiting position is effected by guide pins 23, 24 arranged on the carriage 2, which cooperate with a tilting part guide link 25 of the base body 1, see in particular Figures 10-12 and 21-23 .
  • the tilting part guide link comprises two guide webs, one of the guide pins 23 being guided between them and the other of the guide pins 24 interacting with an outer surface of one of the guide webs.
  • the lower guide bar of the tilting part guide link 25 is free in the area of the front end of the tilting part guide link 25, whereby the guide pin 23 can be inserted into the space between the two guide bars during assembly.
  • the tilting part guide link 25 Starting from the area in which the guide pins 23 are located when the carriage 2 is in the basic position, the tilting part guide link 25 initially runs in a straight line. Before the carriage 2 reaches the waiting position, the guide pins 23, 24 reach a bent area of the tilting part guide link 25 when the pull-out guide is pulled out, as a result of which the tilting part 5 is pivoted about the tilting axis 13 from the holding position into the release position.
  • the curved part of the length of the tilting part guide link 25 can be in the range of 15% to 40%, preferably 20% to 30% of the total length of the tilting part guide link 25 (the lengths being measured along the guideway formed by the guide link).
  • the driver 4 which is formed here by a projecting web section at the rear end of the pull-out rail 20, is held in a recess of the tilting part 5, as in particular in 13 is evident.
  • the carriage 2 is thus first entrained and moved against the force of the draw-in spring 3 from the basic position in the direction of the waiting position.
  • the tilting part 5 is pivoted into the release position, in which the carrier 4 can move out of the recess of the tilting part 5, see in particular 14 .
  • the carriage 2 When the pull-out rail is pulled out further, the carriage 2 remains in the waiting position, in which it is held by the interaction of the guide pin 24 with the bent area of the tilting part guide link 25 .
  • the tilting part guide link 25 can have a small indentation (not visible in the figures) in the area in which the guide pin 24 is located when the carriage 2 is in the waiting position. In this way, a holding device for the carriage 2 is formed when the carriage 2 is in the waiting position and the driver is uncoupled from the carriage 2.
  • the driver 4 abuts the tilting part 5 in the uncoupling and coupling position of the pull-out rail 20 and pivots it in the direction of its holding position.
  • the self-locking of the guide pin 24 in relation to the tilting part guide link 25 is thereby canceled and the draw-in spring 3 subsequently pulls the carriage 2 back into its basic position, with the pull-out rail 20 being carried along.
  • a damper 26 is coupled to the carriage 2 . This dampens the retraction movement of the slide 2 by the retraction spring 3.
  • the draw-in spring 3 acts on the lever 6. This is mounted on the base body 1 such that it can pivot about the first pivot axis 7 , being displaceable with respect to the first pivot axis 7 .

  • the backdrop 11 has a curved course, ie the center line 27 of the backdrop, which is in the 25-27 is drawn is curved. If a tangent is applied to the center line 27 at the point at which the axle pin 10 is located in the basic position of the carriage 2 (this tangent is shown as a dashed line in 10 drawn), the direction 15 in which the lever 6 moves relative to the first pivot axis 7 at the beginning of the displacement of the carriage 2, starting from its basic position in the direction of its waiting position, is on this tangent.

In the further course of the displacement of the carriage 2 in the direction of the waiting position (which in Figure 61 is shown), the displacement of the first pivot axis 7 in relation to the connecting link 30 takes place in the opposite direction to the direction 15. The force of the draw-in spring 3 is thus further stepped down, as it were.

In this way, the draw-in spring 3 can draw the carriage 2 into the basic position. This retraction is dampened by the damper 26 connected to the carriage 2 .
  • the self-retracting device also features a "malfunction recovery" mechanism in the event that the carriage is already in the home position when the retraction guide is retracted.
  • the driver 4 runs against an inclined surface 33 of a projection 32 of the tilting part 5, as a result of which two parts of the tilting part that lie against one another in this area are pressed apart against the elasticity of the material and a gap is opened for the driver 4 to move into the recess of the driver 4 .
