Definitions

  • the present invention relates to a latching mechanism, in particular for an ejection device, with a Schaitelement which is movable along a ulissen- leadership in a housing and can be latched to a projection with a detent recess by the force of an ejection spring.
  • EP 743 032 discloses a latching mechanism for a drawer slide in which a switching element is movably mounted along a slotted guide.
  • the Schaitelement can be latched to a detent recess by the force of a spring.
  • To unlock the switching element can first be moved by a small distance in the closing direction, so that the shadow element is pivoted on a run-up slope and then can be moved along the slotted guide.
  • the distance to unlock the locking mechanism is comparatively large, because first, the switching element must be moved from the locking recess to the opposite starting slope before the switching element can then be pivoted by methods along the run-on slope.
  • a movably mounted head section is provided on the housing with a starting bevel opposite the detent recess, which is biased towards the detent recess.
  • the head portion can be arranged in the latched position of the switching element adjacent to the switching element, preferably also applied to the switching element, so that upon movement of the switching element in the closing direction, the switching element is unlocked immediately and with minimal travel such unlocking can be realized.
  • the head section with the starting bevel can also be in contact with the switching element with a bias, in this case that this can be laterally pivoted and unlocked with a small switching movement, for example by pushing a drawer.
  • the head portion is biased by a spring which is supported on the housing of the slotted guide.
  • the latching mechanism can be made particularly compact, with head section and spring being integrated into the housing.
  • the slotted guide can be formed by groove-shaped channels in the housing, wherein the head section forms one end of the slide guide and forms abutment surfaces for the switching element.
  • the head portion has a leg which engages in an insertion of the Kuiissen Installation and is displaceable by the switching element.
  • the leg of the head portion can thereby act as a kind of pawl, which allows the switching element to pass only in one direction and prevents movement of the switching element in the opposite direction.
  • the leg closes the insertion channel in a first position and releases the insertion channel in a displaced second position to the region with the detent recess. If the switching element shifts the head section by a pressure on a contact surface on the tine], the switching element can lock after leaving the contact surface on the locking guide and the head portion is moved back due to the spring force, so that the leg closes the retraction channel. This prevents that the switching element accidentally does not lock on the locking guide and the functionality of the locking mechanism is impaired.
  • the head portion is preferably mounted linearly displaceable between two stops, for example, the head portion has a pin which engages in a slot on the housing.
  • the sliding path of the head portion may be dimensioned so that the switching element is held almost positively on the locking guide and is pivoted immediately upon movement to the run-on slope of the head portion.
  • the switching element may be formed as a wire which engages with a bent end portion in the Kuiissen arrangement.
  • the locking mechanism according to the invention is preferably used in furniture fittings, in particular in drawer guides.
  • a drawer can be locked in a closed position, in order then to be ejected in an unlocking of the locking mechanism in the opening direction by the force of the ejection spring.
  • other applications for the locking mechanism are possible.
  • the invention will be explained in more detail below with reference to an embodiment with reference to the accompanying drawings. Show it:
  • Figure 1 is a perspective view of an ejection device with a locking mechanism according to the invention
  • Figure 2 is a plan view of the ejector of Figure 1;
  • Figure 3 is a view of the slotted guide of the locking mechanism
  • Figure 4 is an enlarged detail view of the locking mechanism with Schaitele- ment
  • Figure 5 is a perspective view of Detaiidar ein the locking mechanism
  • Figure 6 is a detailed perspective view of the locking mechanism.
  • An ejection device 1 comprises a mounting body 2, on which a driver 4 is movably mounted.
  • the driver 4 is biased by a pull-in spring in the shooting direction, wherein the pull-in spring 3 is fixed at one end to the driver 4 and at the other end to the mounting body 2.
  • the driver 4 is movably mounted along a guideway to the mounting body 2 and may be coupled to a catalystteü, such as a rail of a pullout guide, to act as a self-closing.
  • a damper may be mounted on the mounting body 2.
  • the driver 4 causes a safe entry of an activator in a locking system.
  • an ejector 13 is movably mounted on the mounting body 2, which is latched in a closed position of the furniture part via a latching mechanism.
  • the ejector 13 is biased via an ejection spring in the opening direction, which is arranged in a spring housing 5.
  • a latching mechanism is provided with a housing 6, on which a head portion 7 is slidably mounted.
  • a housing 6 located in the housing 6 is a slotted guide, in which a Schaitelement 9 is movably mounted.
  • the switching element 9 is formed as a wire which engages with an angled end portion 10 in the Kulissenf leadership.
  • the switching element 9 is coupled on the opposite side with the driver 4.
  • the housing 6 is shown with the slide guide in detail.
  • the slide guide is formed by groove-shaped channels, which are formed integrally with the housing 6 made of plastic.
  • a projection 60 is arranged with a detent recess 61.
  • the slotted guide comprises a loop-shaped portion with a retraction channel 62, which leads the bent end portion 10 of the switching element 9 to the detent recess 61.
  • the switching element 9 can then be moved by a positive guide through the head portion 7 in an extension channel 63 and then moved by the force of the ejection spring to a junction 64, so that the projection 60 is bypassed by the switching element on the loop-shaped portion. From the branch 64, the switching element 9 can be moved along an outlet 65.
  • FIG. 4 shows the latching mechanism with the switching element 9.
  • the switching element 9 moves from the branch 64 to the head portion 7, wherein a leg 70 is inserted into the insertion channel 62 and closes it.
  • the switching element 9 must therefore initially engage with the angled end section 10 on a contact surface 71 on the leg 70 in order to displace the head section 7 in order then to reach the region with the detent recess 61.
  • the contact surface 71 is arranged at an angle to the longitudinal direction of the housing 6, so that the switching element 9 presses against the contact surface 71 and a side surface of the projection 60.
  • the head portion 7 is displaced in the longitudinal direction of the housing and the switching element 9 can reach into a receptacle 72 on the head portion 7.
  • the head section 7 is now moved back again by the force of a spring 8, so that the leg 70 closes the entry channel 62. This prevents the switching element 9 accidentally back into the Einfahrkana! 62 arrives.
  • the switching element 9 is now pulled due to the force of the ejection spring in the opening direction, ie to the left in Figure 4.
  • the angled end portion 10 is latched to the detent recess 61
  • the head portion 7 has a run-on slope 74, which is arranged opposite the detent recess 61.
  • the run-up bevel 74 is formed on a projection 73, whose tip is arranged offset to the detent recess 61, so that upon movement of the switching element 9 in the closing direction, ie to the right in Figure 4, the bent end portion 10 of the switching element rests against the run-on slope 74 and the switching element 9 is pivoted.
  • a receptacle 75 is formed on the head portion 7 adjacent to the run-on slope 74, on which the extension channel 63 begins on the housing 6. If the switching element 9 reaches the receptacle 75, the switching element 9 can be moved back to the branch 64 due to the force of the ejection spring.
  • the locking mechanism is shown in an exploded view.
  • the head portion 7 has on the side facing away from the run-up slope 74 a
  • the head portion 7 is slidably held in a strip-shaped receptacle 11 of the housing 6 in the longitudinal direction.
  • the head portion 7 has a downwardly projecting pin 78 which is held in a slot 69 on the housing 6. Further, a projection 76 is formed on the head portion 7, which abuts against a side wall 6 of the housing 6.
  • a resilient wall portion 67 is further formed, which defines a channel portion 66 adjacent to the projection 60.
  • the resilient wall portion 67 is disposed adjacent to a recess 68, so that act on a lower opening movement on the switching element 9 lower impact forces.
  • the head portion 7 can act as a pawl even with an unlocking of the switching element 9 in a movement of the detent recess 61, which prevents movement of the switching element 9 back into the detent recess 61.
  • the switching element 9 has to move the head section 7 slightly in the closing direction during a movement in the closing direction for an unlocking operation and thereby pivot into the receptacle 75 of the head section 7.
  • the head portion 7 is moved back to the locking recess 61 after unlocking, wherein the distance between the run-on slope 74 and a tip 17 is selected on the projection 60 so that it is smaller than the diameter of the angled end portion 10 is.
  • the switching element 9 after unlocking no longer accidentally get into the detent recess 61.
  • the distance between the projection 73 and the projection 60 on the housing 6 is dimensioned so that the switching element 9 can be moved with the angled end portion 10 in the catch recess 61, even if the switching element 7 is arranged in an end position and by the spring 8 is biased in this end position.
