Description

The The invention relates to a pull-out protection, with the help of which prevented that can be done by simultaneously pulling out several drawers from a piece of furniture the stability of the furniture endangered and as a result it turns over.

in the Related to the invention being furniture is all kinds of home furniture, however also operating equipment such as tool cabinets, workshop carts, filing cabinets and other more understood. Common feature of all this furniture is, that they have at least two extendable furniture elements. typical Examples of extendable furniture elements are drawers, but also the inserts in so-called "pharmacist cabinets".

all This extendable furniture elements is common that they are in solid state over the footprint of the furniture protrude and thus exercise a tilting moment on the furniture and its stability affect. If several of these pull-out furniture elements pulled out at the same time are, can all the furniture fall over and as a result damage to persons and things can arise.

Out For this reason, the relevant regulations require, for example the professional association or to obtain the seal "tested safety" (GS), that the extendable furniture elements provided with a pull-out protection.

The Pull-out safeguards available on the market and on the market have several disadvantages. There are various extract safeguards, in the middle of the furniture at the back wall a linear guide for locking members exhibit. On this linear guide is for every drawer is a relatively expensive thawed one Locking provided, which with a pawl in a corresponding Recess in the middle of the rear end of the drawer engages.

adversely At this pull-out protection is their complex construction, which is naturally in high Production costs reflected. Furthermore is the stability This construction is relatively low, since both the linear guide as also with the pull-out corresponding recess in the Drawer respectively at the least stable areas of the furniture respectively the drawer are provided. Besides, it is in case of a defect almost impossible, to repair the pull-out protection without draining the furniture and closing it completely disassemble.

Out the field of office furniture, in particular with roll containers, so-called pull-out safeguards are known, at the front of the furniture, right and left of the drawer to be secured are arranged. at these pull-out locks are provided on the drawers backdrops, when opening a drawer for it should ensure that the other drawers are locked. adversely At this construction is that with this pull-out protection several Drawers open at the same time can be so that the overturning of the furniture not reliable is prevented. These pull-out safeguards only ensure that if one or more drawers are already open, no more drawer more can be pulled out.

For example, from the DE 43 15 452 A1 or the DE 195 47 948 A1 Pull-out devices are known, which are arranged on the front of the cabinet, right and left of the drawer to be secured. In these pull-out locks, the drawers are locked by an elaborate system of two control slides per drawer or a control element rotatably mounted on a locking slide.

all Excerpts are common that they are very complex and so that they are expensive and prone to failure. Furthermore they are in their dimensions on the height of the secured drawers Voted.

Of the Invention has for its object to provide a pull-out protection, which is simple, mechanically very resilient and effective prevents more than one drawer or more than a pull-out furniture element open at the same time or from the furniture can be pulled. Furthermore, the pull-out protection according to the invention is intended be flexible.

These The object is a pull-out protection for a pull-out furniture element, according to the preamble of claim 1, achieved by a characteristic dimension of the locking members corresponds to a pitch, in which the pull-out furniture element in a piece of furniture can be mounted.

The Pull-out protection according to the invention is very simple and is independent in size the height and the number of drawers to be backed up, which is positive the manufacturing and assembly costs. This makes it possible for the extendible furniture elements, in particular drawers of different heights, without changes to the pull-out protection according to the invention in the furniture element to assemble in a conventional manner.

In addition, the invention is Off zugsicherung extremely reliable because the latch can be attached directly to the pull-out furniture element and thus whenever a pull-out furniture element is open, belonging to the open furniture element latch between two adjacently arranged locking members and effectively prevents the opening of other extendable furniture elements.

With Help of the pull-out protection according to the invention it is also impossible two extendable furniture elements at the same time undress. If you do this with two drawers one with the pull-out protection according to the invention equipped furniture should try, let Do not open any of the two drawers, causing a tipping over of the furniture safely prevented.

A inexpensive and still very stable design variant The invention provides that the linear guide formed as a C-profile is.

advantageously, can the locking members may be formed as rollers having a cooperating with the C-profile Have groove. Of course it is also possible instead of rolls that are naturally rotationally symmetric, rectangular or square sliding blocks with a longitudinal groove as Provide locking members, wherein the longitudinal groove serves to the sliding blocks in the C-profile.

Further advantageous embodiments of the invention provide that the linear guide on an end stop for both ends having the locking members, more preferably between the end stops and a distance is provided to the locking members with a height of the bolt corresponds.

Thereby is guaranteed that as soon as a latch between two juxtaposed Locking members is located, all locking members of the pull-out in the linear guide are fixed. As a result, opening a second drawer is prevented because no second bolt fits between the locking members.

Around the introduction to facilitate the bolt between two locking members, it is provided that First, the locking members in the direction of the longitudinal axis of the linear guide at least beveled at one end are. This results in rotationally symmetrical locking members, which are designed as roles, sort of by itself. simultaneously It is advantageous if the latch at one or both ends bevelled is.

Around to improve the blocking effect of the pull-out protection according to the invention, it is advantageous if viewed in the direction of the longitudinal axis of the linear guide in the middle of the locking members located outer surface thereof, at least on the side facing the latch orthogonal to the extension direction the extendable furniture element runs. This property is given in role-shaped locking members. This does not make it possible for yourself if with big Force is pulled on a second drawer, that the locking members sideways dodge and room for make the second latch of a second drawer. Thus, the Loading capacity of the pull-out protection according to the invention further increased.

extendable furniture elements within the meaning of the invention, As already mentioned, a drawer or an excerpt of a pharmacy cabinet. Of course it is the invention is not for use in connection with these extendable furniture elements limited. It is rather possible the pull-out protection according to the invention everywhere use, where components or assemblies of a piece of furniture are designed to be pulled out and to avoid having more than one of these assemblies pulled out at the same time.

The The invention also relates to a tool cabinet, a roll container or a cabinet with at least two pull-out furniture elements, with at least one and a maximum of four pull-out locks after one of the preceding claims are.

If four pull-out fuses are provided, it is possible to use one from both sides accessible To provide tool cabinet, the drawers of this tool cabinet can be pulled out to the front and to the rear. there is guaranteed that forward and backward only one drawer at a time can be pulled out. It is possible, however, a drawer at the same time to pull forward and a drawer to the rear. This is Therefore harmless, because by the simultaneous taking off of two Drawers in opposite directions the stability of the Cabinet is improved.

Further Advantages and advantageous embodiments of the invention are the subsequent drawing, the description and the claims can be removed.

All in the drawing, the description and the claims described Features can both individually and in any combination essential to the invention be.

Description of the embodiments

In 1 is a top view of a furniture 1 shown. In the view according to 1 is a drawer 3 recognizable, the one across the entire width of the piece of furniture 1 extending handle 5 having. The handle 5 is with the drawer 3 connected. If you hold the handle 5 in the direction of an arrow 7 pulls, becomes the drawer 3 open.

The guides of the drawer 3 are in 1 not shown.

Right and left of the drawer 3 each is a bar 9 on the side walls 11 with the drawer 3 connected. This means that the latch 9 also in the direction of the arrow 7 moved when the drawer 3 by pulling on the handle 5 is opened.

Right and left of the drawer 3 are linear guides 13 provided that firmly with the furniture 1 are connected. This in 1 illustrated embodiment of a linear guide 13 , which is shown enlarged in detail X, comprises a C-profile 15 , In the C-profile 15 are roles 17 with a groove 19 added. The groove 19 serves the roles 17 on the one hand on the C-profile 15 to fix and at the same time moving the rollers 17 in the C-profile. The fixation of the rollers 17 takes place by the interaction of the groove 19 with thighs 21 of the C-profile 15 , It goes without saying that the dimensions of the C-profile 15 on the diameter D of the roll 17 and the groove 19 are tuned so that on the one hand the role 17 With little play, so the role 17 can not cant, and the role 17 easy in the C-profile 15 can be moved back and forth.

A section 23 the role 17 protrudes above the C-profile 15 out and works with the latch 9 together, at the drawer 3 is attached. The section 23 the role 17 is in the extension of the bolt 9 arranged. This means that the bolt 9 on a section 23 a role 17 meets when the drawer 3 is opened.

The blocking effect of the pull-out protection according to the invention is described below in connection with the 2 and 3 explained in more detail. Same components have the same reference numerals and the respect 1 The said applies accordingly.

The 2 and 3 show a view along the line AA 1 and show, among other things, the sidewalls 11 the drawer 3 as well as a bar 9 , In 2 is left of the drawers 3 is the C profile 15 and a total of seven roles 17 , not all of which have been provided with reference numerals. The C-profile 15 has a lower stop 25 and an upper stop 27 , The attacks 25 and 27 limit the path of roles 17 in the direction of a longitudinal axis 33 the linear guide 13 ,

From the 2 it becomes clear that a lower edge 29 the latch 9 is arranged so that the extension of the lower edge 29 between two roles 17 runs. This relationship is indicated by a dashed line without reference number to the in 2 upper latch 9 indicated.

The C-pillar 15 facing ends of the bolt 9 have a slope 31 on. If, for example, the upper drawer 3 in the direction of the arrow 7 moved and thereby opened, the moves on the upper drawer 3 fastened bolts 9 also in the direction of the arrow 7 and penetrates with his slope 31 between two roles 17 one. This position is in 3 shown.

Out 3 it becomes clear that the four are below the top bolt 9 located roles 17 through the bottom 29 of the bolt 9 and the lower stop 25 are trapped in and no longer in the direction of the longitudinal axis 33 of the C-profile 15 can move. As a result, the in 3 lower drawer 3 Do not open anymore because of the lower drawer 3 belonging bars 9 not between the two lowest roles 17 can push. As a result, the bolt will 9 and with it the entire lower drawer 3 blocked and can not be opened.

When the upper drawer is fully open (not shown in 3 ), then lies the supreme role 17 at the top stop 27 so that also the remaining roles 17 in the direction of the longitudinal axis 33 of the C-profile 15 are locked. For this reason, it is advantageous if a height H of the bolt 9 the distance A between the topmost roller 17 and the top stop 27 with closed drawers 3 (please refer 2 ) corresponds.

It has also proved to be advantageous if a diameter D of the rollers 17 a grid (not shown) corresponds, within which the drawers 3 in which furniture can be fixed. This makes it possible to install different high drawers in the furniture without making changes to the pull-out protection according to the invention.

In 4 is an embodiment of a provided with pull-out protections tool cabinet 37 shown in a side view. Characteristic of this tool cabinet 37 is that the drawers 3 both forward and backward from the tool cabinet 37 can be pulled out. As a result, both are on the front of the tool cabinet 37 and a back of the tool cabinet each two pull-out 13 with C-profiles 15 and roles 17 arranged. Accordingly, the bars have 9 one bevel at each end 31 on.

In 5 is the second drawer from bottom to left out of the tool cabinet 37 pulled out. As a result, as already related to the 3 described, ensure that the bottom drawer 3 can not be opened anymore. At the same time is in 5 also clearly visible that now the above the bolt 9 the middle drawer 3 located roles 17 on the one hand from the bolt 9 the middle drawer and on the other hand from the top stop 27 are locked in the direction of the longitudinal axis of the linear guide. This means that even the top drawer is no longer forward, that is in 5 to the left, from the tool cabinet 37 can be moved out. Because the bar 9 the middle drawer 9 when opened, the above the middle bar 9 located roles 17 has raised by the dimension "H" hits the bottom edge 29 of the bolt 9 the top drawer 3 on the middle of the rolls 17 meets (see the dashed line without reference numeral), so that even by impetuously pulling the top drawer to the left to the top stop 27 and the latch 9 the middle drawer 3 acting forces are negligibly small.

This example illustrates the resilience and simplicity of the pull-out protection according to the invention. Another advantage of the pull-out protection according to the invention is also in 5 recognizable. Nevertheless, the middle drawer 3 forward from the tool cabinet 37 pulled out, the top drawer can 3 to the rear from the tool cabinet 37 be pushed out, as the front extractor 13 and the rear pull-out protection 13 of the tool cabinet 37 work completely independently. As a result, it is possible to have only one drawer 3 pull out to the front and / or pull out a second drawer to the rear. The simultaneous removal of one drawer each to the front and to the rear improves the stability of the tool cabinet 37 ,

In 6 is a front view of the tool cabinet according to the invention 37 according to 4 and 5 shown.

For clarity, the linear guide 13 only shown by a dashed line. The top stop 27 is also shown by a dashed line. In a panel 41 is a castle 43 intended. By pressing the lock 43 can lock cylinders 45 below the top stop 27 in the linear guide 39 be introduced. If the diameter of the lock cylinder 45 the distance "A" between the topmost roller 17 and the top stop 27 (please refer 2 ), can by pressing the lock 43 and the associated engagement of the lock cylinder 45 in the linear guides 39 in a simple and very effective way all drawers 3 of the tool cabinet 37 be closed.

In the embodiments described above, the locking members are rollers 17 with a groove 19 educated. It goes without saying that the locking members, for example, as a sliding blocks 45 with a groove 19 can be trained. Such a nut 45 is in 7 shown in three views.

The nut 45 is with the groove 19 in the C-profile 15 (not shown) recorded. In this case, a part of the sliding blocks protrudes over the C-profile 15 out, according to the section 23 the roles 17 (please refer 1 ). So that the bars 9 with her slope 31 good between two adjacent nuts (not shown) can penetrate, it is recommended that the sliding blocks 45 with a chamfer 47 to provide, which with the slope 31 of the bolt 9 interacts. Otherwise, the operating principle remains unchanged.
