Definitions

  • the invention relates to a pull-out guide for a sliding element, in particular a drawer, shelf or drawer frame, with a carcass rail that can be fastened to a body, with a pull-out rail that can be fastened to a sliding element, which is guided so that it can be displaced relative to the carcass rail and has an upper rail leg in the installed position, the upper side of which has a Forms support for the push element, and with a front adapter which is attached to a front end in the pull-out direction of the pull-out rail and has a locking projection which, in an initial position, protrudes upwards through a recess in the upper rail leg over the upper side and can be deflected downwards from the initial position against the action of a restoring force into a position flush with the upper side.
  • Such a pull-out is, for example, by the WO 2019/191793 A1 known.
  • the locking projection can be pivoted from the initial position about an axis that runs horizontally in the installed position into the position that is flush with the upper side.
  • the locking projection is biased into the initial position by means of a separate leaf spring.
  • the locking projection is provided on the free end of a separate tab, the other end in the front adapter
  • the present invention is based on the object of specifying an alternative type of locking for a pull-out guide of the type mentioned at the outset.
  • this object is achieved in that the locking projection is mounted such that it can be deflected exclusively linearly in a direction at right angles to the upper side of the upper rail leg.
  • the locking projection is arranged on the upper side on the center of a bar of a spring bar of the front adapter that can be elastically deflected linearly downwards, which is arranged below the upper rail leg and parallel to the upper rail leg and is freed in the front adapter by means of two recesses, which are on both sides of the spring bar are arranged. Due to the central arrangement on the spring bar, it is ensured that the locking projection is only deflected linearly downwards in the direction at right angles to the upper side of the upper rail leg. The two-sided connection of the two web ends to the front adapter results in a high elastic restoring force.
  • the locking projection is arranged eccentrically on the upper side of a spring bar of the front adapter that can be elastically deflected linearly downwards, which is arranged below the upper rail leg and parallel to the upper rail leg and is freed in the front adapter by means of two recesses, which are on both sides of the spring bar are arranged, wherein the spring bar has a cross-sectional reduction on the side of the bar that is shorter with respect to the locking projection than on the longer side of the bar.
  • the two web sides of the spring bar are designed to be equally resilient, although they are of different lengths.
  • the spring bar advantageously extends in the longitudinal direction of the drawer rail in order to be able to design the spring bar to be sufficiently long for a desired deflection.
  • the front adapter can, for example, have a plate section which is arranged below the upper rail leg and parallel to the upper rail leg and in which the spring bar is left free by means of the two recesses.
  • the two recesses are mirror-symmetrical to each other with respect to a web center plane of the spring bar and are formed by two slots closed at both ends, which define the spring bar between them.
  • the two slots advantageously run parallel to one another, at least for the most part.
  • the front adapter has on both sides two laterally outwardly projecting latching tabs, which are laterally inwardly free through the cutouts and can be elastically deflected laterally inward into the cutouts.
  • the front adapter is attached to or plugged into the front end of the drawer rail, causing the latching tabs to be elastically deflected inward until they can snap into a recess in the drawer rail, thereby locking the front adapter to the drawer rail.
  • the locking projection is particularly preferably formed on the spring bar and the front adapter is made of plastic, for example as an injection molded part.
  • the body rail and the drawer rail are either mounted directly next to one another or can be displaced relative to one another by means of a middle rail arranged between them.
  • the invention also relates to a piece of furniture with two pull-out guides designed as above and with a pusher element which is arranged between the two pull-out guides and rests on the upper horizontal rail legs of the two pull-out rails, the pusher element on the two upper rail legs counter to the pull-out direction up to a Locking position is pushed, in which the locking projections of the two front adapters engage upwards in each case in the underside recesses of the pusher element to couple the pusher element in and against the pull-out direction with the pull-out rail.
  • the pull-out guide 1 shown comprises a body rail 2 that can be fastened to a furniture body, a drawer rail (extension rail) 3 that can be fastened to a drawer, and a center rail 4 that is slidably mounted on the body rail 2 and on the drawer rail 3.
  • the rails 2, 3, 4 are relative via rolling elements 5 mutually displaceable in the longitudinal direction.
  • Two body legs 6 are provided on the body rail 2 for attachment to the furniture body.
  • the drawer rail 3 can be pulled out relative to the cabinet rail 2 in the extension direction 7 to an extended end position (not shown), with the center rail 4 allowing the drawer rail 3 to be fully extended relative to the cabinet rail 2. If full extension is not desired, no middle rail is required and the drawer rail 3 is slidably mounted directly on the cabinet rail 2 .
  • the drawer rail 3 has an upper (horizontal) rail leg 3a, the flat outer or top side 8 of which forms the support for the drawer, and two parallel (vertical) side legs 3b , which are connected to one another at the top by the upper rail leg 3a.
  • the drawer rail 3 can also be a U-shaped rail profile that is open to the side or have a different profile geometry, but it always has an upper (horizontal) rail leg 3a with a flat upper side 8.
  • a front adapter 10 is attached to the front end of the drawer rail 3 in the pull-out direction 7 .
  • the front adapter 10 is preferably plugged onto or onto the front end of the drawer rail 3 and has a flat plate section 11 which is arranged below the upper rail leg 3a, here in the interior of the drawer rail 3, and runs parallel to the upper rail leg 3a.
  • a spring bar 13 is left free in the plate section 11 by means of two recesses designed here, for example, as longitudinal slots 12 , which is connected to the plate section 11 at its two bar ends and which—like the longitudinal slots 12 closed at both ends—extends in the longitudinal direction of the drawer rail 2.
  • the two longitudinal slots 12 are arranged on either side of the spring bar 13 to define the spring bar 13 therebetween.
  • the longitudinal slots 12 are mirror-symmetrical to each other with respect to a web center plane of the spring bar 13 and mostly run parallel to one another. For reasons of space, the two longitudinal slots 12 are reduced to a small distance only at their rear slot end in the pull-out direction 7 .
  • the spring bar 13 has a locking projection 14 at the center of its bar on the upper side, which in a starting position ( Figure 4a ) up through a recess 15 of the upper rail leg 3a through to the top 8 is high. From this initial position, the locking projection 14 can be moved in a direction 16 perpendicular to the plate plane of the plate section 11 or to the upper side 8 against the action of an elastic restoring force to an end position flush with the upper side 8 ( Figure 4b ) are deflected. Due to the central arrangement on the spring bar 13, the locking projection 14 is deflected exclusively linearly in the direction 16 perpendicular to the upper side 8 downwards.
  • the plate section 11 has two laterally outwardly projecting locking tabs 17 on both sides, which are freed inwardly through the longitudinal slots 12 and laterally inwardly into the Longitudinal slots 12 are elastically deflected into it.
  • the front adapter 10 is inserted onto the front end of the drawer rail 3, as a result of which the latching tabs 17 are elastically deflected inwards by the side limbs 3b of the drawer rail 3 until they can snap into a recess 18 in the side limbs 3b and the front adapter 10 on the drawer rail 3 is locked.
  • the front adapter 10 is preferably an injection molded part made of plastic, with the locking projection 14 being integrally formed on the spring bar 13 .
  • Figs. 5a-5c the assembly of a drawer 20, which has a flat drawer bottom 21 , on the pull-out guide 1 is shown.
  • the drawer 20 is placed with its rear end on the front end of the horizontal drawer rail 3 in the pull-out direction 7 and thus also on the locking projection 14, as a result of which the locking projection 14 is pressed down from the drawer 20 into the flush position with the upper side of the rail 8 and the drawer 20 rests with its drawer bottom 21 on the horizontal rail top 8 of the drawer rail 3 ( Figure 5a ).
  • the elastic restoring force of the locking projection 14 is therefore less than the weight of the drawer 20.
  • the drawer 20 is then pushed further on the horizontal top side 8 of the rail in the opposite direction to the pull-out direction 7, with the locking projection 14 remaining pressed down by the drawer 20 into the position flush with the top side 8 of the rail ( Figure 5b ).
  • the drawer 20 is pushed on the drawer rail 3 against the pull-out direction 7 into a locked position ( Figure 5c ), in which the locking projection 14 engages upwards in a recess 22 on the underside of the drawer underside 21 and is thus again in its initial position.
  • the locking projection 14 engages, viewed in the longitudinal direction of the drawer rail 3, with minimal play in the recess 22, whereby the drawer 20 is coupled for movement to the drawer rail 3 in and counter to the pull-out direction 7, ie in the horizontal direction.
  • the locking projection 14 is arranged eccentrically on the spring bar 13, here closer to the front end of the bar in the pull-out direction.
  • the spring bar 13 has a cross-sectional reduction, here a reduced bar width, on the bar side that is shorter in relation to the locking projection 14 compared to the longer bar side .
  • the two web sides of the spring web 13 are designed to be equally resilient, although they are of different lengths.
