Description

The present invention relates to an arrangement of two pull-out stops arranged adjacent to one another for a plurality of drawers which are arranged one above the other in a body of a piece of furniture and can be displaced parallel to one another in a pull-out direction on a coupling part for coupling the pull-out stops according to the preamble of claim 1.

The invention also relates to a piece of furniture.

Generic pull-out locks and arrangements of such pull-out locks in a piece of furniture with several drawers arranged one above the other in a body are known, for example, from DE 20 2018 104 659 U1 or the DE 105 47049 C2 famous.

Such pull-out locks are used on the one hand to ensure that only one of several drawers arranged one above the other in a piece of furniture can be opened, and on the other hand to enable central locking of all drawers.

If two rows of such drawers arranged one above the other are arranged on such a piece of furniture, it is from the U.S. 2010 0148648 A1 known, for example, to block drawers arranged next to one another by means of a pin which can be pushed through a cabinet wall between the two rows of drawers.

The object of the present invention is to provide an arrangement of two pull-out locks arranged adjacent to one another for a plurality of drawers arranged one above the other in a body of a piece of furniture and which can be displaced parallel to one another in a pull-out direction on a coupling part for coupling the pull-out locks, with which it is possible by pulling out a single drawer to lock all other drawers.

This object is achieved by an arrangement with the features of claim 1.

The arrangement according to the invention of two pull-out locks arranged adjacent to one another for a plurality of drawers arranged one above the other in a body of a piece of furniture and displaceable parallel to one another in a pull-out direction on a coupling part for coupling the pull-out locks has respective pull-out locks, in which each of the pull-out locks has a plurality of pull-out locks in a guide along a longitudinal axis the guide has displaceably guided locking slides, each with a stop protruding from the guide.

Each of the pull-out locks also has a locking stop, which is guided in a displaceable manner in the guide, for blocking a possible displacement path of the locking slide.

An actuating element is provided for each drawer, which is arranged in the guide such that it can be pivoted about a pivot axis perpendicular to the pull-out direction and to the longitudinal axis of the guide by pulling out the drawer in the pull-out direction by a pivot angle.

Each of the actuating elements is in contact with an associated stop of one of the blocking slides and the associated blocking slide can be displaced by pivoting one of the actuating elements.

A displacement of one of the locking slides in the guide blocks a displacement of the other locking slides and thus a pivoting of a further actuating element (and thus a pulling out of a second drawer).

The coupling part has a rocker with two coupling arms that are separated from one another by a pivot axis and that protrude into a displacement area of the locking stops of the pull-out locks.

The rocker can be pivoted by pivoting one of the actuating elements and the associated shifting of the associated blocking stop in such a way that a shifting of the blocking stop of the other of the pull-out stops is blocked.

With such an arrangement it is possible that even in two adjacent rows of drawers that can be pulled out one above the other, only one of the drawers can be pulled out, while all the other drawers are blocked by the coupling of the two pull-out locks via the coupling part.

Advantageous variants of the invention are the subject matter of the dependent claims.

According to an advantageous embodiment variant, free ends of the coupling arms are bent over in the same direction perpendicular to the longitudinal extension of the rocker.

According to an advantageous development, at least one of the coupling arms of the rocker is designed with a parallel offset. This makes it possible to arrange the pivot axis closer to an imaginary connecting line between the two locking levers.

According to a further advantageous embodiment variant, the coupling part has a housing with two guide grooves provided on opposite end faces and a bearing point for supporting the pivot axis of the seesaw provided between the two coupling arms, with each of the coupling arms being guided in one of the guide grooves.

By accommodating the rocker in a housing with a bearing for the rocker, an extremely simple assembly of the coupling part in a piece of furniture is made possible. The guide grooves in the housing also enable the coupling arms to be precisely guided in terms of movement.

The design of at least one of the coupling arms of the rocker with a parallel offset also makes it possible to keep the overall height of the housing significantly smaller than would be possible with a rocker with coupling arms that merge into one another in a straight line.

According to an advantageous development, guide grooves for fixing the position of the coupling part on a body wall of the piece of furniture in a direction parallel to the longitudinal extent of the rocker are formed on an edge of a side wall of the housing connecting the end faces to one another.

The furniture according to the invention with several drawers arranged next to and one above the other in a body and at least two pull-out stops to prevent several drawers from being pulled out at the same time is characterized by an arrangement of two pull-out stops and a coupling element coupling them to one another as described above.

In an advantageous embodiment variant, the coupling part is mounted in a recess in a body wall of the piece of furniture, with the body wall dividing the furniture body into two separate compartments in which several drawers are arranged one above the other and coupled to one another via one of the pull-out locks.

In the 1 and 5 an arrangement of two pull-out locks 3, 4 arranged adjacent to one another and a coupling part 5 for coupling the two pull-out locks 3, 4 is shown. add that 1 reinstatement

The two pull-out locks 3, 4 are fixed to a body wall 2 on opposite sides of the body wall 2 here.

The coupling part 5, which has a rocker 51 with two coupling arms 52, 53 separated from one another by a pivot axis 54, is accommodated here in a recess provided for this purpose in an upper end face of the body wall 2.

In principle, the pull-out locks 3, 4 correspond to a structure known from the prior art.

As in the 2 and 3 is shown, each of the pull-out locks 3, 4 has a plurality of locking slides 32, 42 which are guided in a guide 31, 41 so as to be displaceable along a longitudinal axis of the guide 31, 41 and each have a stop 33, 43 protruding from the guide 31, 41.

The guides 31, 41 are designed here as approximately C-shaped guide rails, which are embedded in a longitudinal groove provided for this purpose in the body wall 2, as is shown in 4 is shown.

It is also conceivable to fasten the guides 31, 41 on the upper side of the body wall 2 or to form the guide itself as part of the body wall 2.

The locking slides 32, 42 are slidably guided in a guide groove of the guide 31, 41.

In the area of an upper end of the guides 31, 41 is in the guides 31, 41 slidably guided locking stop 34, 44 is arranged, as for example in the 1 and 5 as can be seen, in the preferred embodiment variant shown here is designed as a blocking shoe protruding perpendicularly from the plane of the side surface of the body wall 2 and with which the displacement path of the blocking slides 32, 42 in the groove of the guide 31, 41 can be limited. The other, here lower end of the guides 31, 41 is closed, for example, by a plug (not shown here), so that the locking slides 32, 42 are also prevented from being displaced downwards.

Each of the locking slides 32, 42 is operatively connected to an actuating element 35, 45, which can be pivoted in the guide about a pivot axis 37, 47 perpendicular to the extension direction x and to the longitudinal axis of the guide 31, 41 by pulling out a drawer in the extension direction x by a pivot angle α 31, 41 is slidably arranged.

By pivoting the actuating element 35, 45, the locking slides 32, 42 arranged adjacent to one another are pushed apart relative to one another so far that pivoting of a further actuating element 35, 45 due to a lack of free displacement path within the guide 31, 41 is prevented.

Preventing the pivoting of a second control element prevents a second drawer from being pulled out in the pull-out direction, since each of the control elements 35, 45 holds, for example, a pin attached to the side of the drawer (not shown here) in a locking groove provided for this purpose in the control element 35, 45 , The pin only by pivoting the actuating element 35, 45 can be released.

Each of these adjusting elements 35, 45 is, as in the 2 and 3 respectively. 6 and 7 is shown, at an associated stop 33, 43 of the locking slide 32, 42 at.

Accordingly, by pivoting one of the adjusting elements 35, 45, as is shown by way of example in 7 is shown, the associated locking slide 32, 42 shifted.

How further in the 1 until 8th is shown, the coupling arms 52, 53 of the rocker 51 of the coupling part 5 protrude into a displacement range of the locking stops 34, 44 of the pull-out locks 3, 4.

In a neutral position, in which all of the drawers are closed, ie are fully pushed into the furniture body, the rocker 51 is aligned such that, as in 1 shown, bottoms of the coupling arms 52, 53 are at a predetermined distance from the tops of the locking stops 34, 44 and thus allow any drawer to be opened.

If one of the drawers is pulled out, one of the adjusting elements 35, 45 in the in 7 example shown, the actuating element 45 is pivoted so that the corresponding stop 43 moves the locking slide 42 upwards so far that the locking stop 44 as shown in FIG 5 is shown, the coupling arm 53 pushes up.

The pivoting of the coupling arm 53 upwards simultaneously causes the other coupling arm 52 of the rocker 51 to pivot downwards, so that the coupling arm 52, as in FIG 5 shown rests on the locking stop 34 in such a way that the locking stop 34 is prevented from being pushed upwards.

Due to the fact that this locking stop 34 cannot be moved upwards, pivoting of one of the adjusting elements 35 on the in 5 left side of the body wall 2 is prevented, so that all the drawers on the left of the body wall 2 cannot be opened.

The rocker 51 can thus be pivoted by pivoting one of the actuating elements 35, 45 and the associated shifting of the associated blocking stop 34, 44 in such a way that a shifting of the blocking stop 34, 44 of the other of the pull-out blocks 3, 4 is blocked.

The coupling part 5 is in detail in the 9 until 13 shown.

As in the 9 , 10 and 12 shown, the free ends of the coupling arms 52, 53 are preferably bent over in the same direction perpendicular to the longitudinal extent of the rocker 51 and thus enable the guides 31, 41 of the pull-out stops 3, 4 arranged on both sides of the body wall 2 to be arranged directly opposite one another.

Next is as in the 11 and 12 is shown, one of the coupling arms 52, 53, here the coupling arm 53 of the rocker 51 is formed with a parallel offset. It is also conceivable to form both coupling arms 52, 53 of rocker 51 with such a parallel offset.

In order to further simplify the installation of such a coupling part, the coupling part 5, as shown in FIGS 2 , 4 , 6 , 8th , 9 and 10 is shown, preferably a housing with two guide grooves 56 provided on opposite end faces and a bearing point 58 for supporting the pivot axis 54 of the rocker 51 provided between the two coupling arms 52, 53. Each of the coupling arms 52, 53 is in one of the guide grooves 56 led.

To prevent movement of the housing 55 in a direction parallel to the longitudinal extent y of the rocker 51, guide grooves 57 for fixing the position of the coupling part 5 on a body wall 2 of the piece of furniture are formed on an edge of a side wall of the housing 55 connecting the end faces to one another.

The coupling part 5 is mounted in a recess in the body wall 2 of the piece of furniture. This body wall 2 divides the furniture body into two separate compartments, in each of which several drawers are arranged one above the other. The pull-out locks 3 , 4 on both sides of the body wall 2 are coupled to one another via the coupling part 5 .
