Description

The invention relates to a locking device for fixing two pieces of furniture together after the generic term of claim 1.

Extension walls in their most varied design are well known. Great popularity also enjoy box-shaped office or shelf walls. These can be, for example from individual container or general box-shaped Basic units, which in the following also partly as Modules are called, assembled with high variability become. For example, the modules can be open can be left, but can also front with a variety of Be provided flaps. Likewise, drawer elements be built-in etc.

In such, in modular design assembled Shelf wall, for example, then poses the problem that individual modules as simple as possible, but effective to fix each other so that overall a stable Overall construction results.

The object of the present invention is, therefore, a to provide an improved locking system for furniture pieces, in particular for box-shaped modular or basic units, to attach such items together or to fix.

The object is according to the invention in the claim 1 specified characteristics solved. Advantageous embodiments The invention are specified in the subclaims.

According to the present invention, a highly efficient Connection system created with which the individual too connecting pieces of furniture can be provided from home. The basic principle is that any with appropriate Provided connecting and locking device Pieces of furniture, for example box-shaped or container-shaped Basic or modular units, set to each other can then, for example, only on the patch Module unit the locking or locking device provided there to operate, causing both pieces of furniture be firmly connected with each other.

The structure is preferably such that not only similar ones or functionally identical, but in particular identical Locking base sections provided on each piece of furniture which are positioned so that with appropriate Structure provided on the two pieces of furniture Locking elements each congruent to each other come lie. With the same structure can then alternately, depending on which locking base portion lighter is accessible, at this the interlock with the respectively other locking section are made. Prefers The locking is only by pushing in and twisting an actuating member causes.

Preferred is a bayonet-type locking mechanism intended. For this purpose, certain projections or depressions at the individual, interacting with each other Sections and elements designed to be the desired To realize a bayonet-type locking mechanism. Preferably provided locking arms can from a central central portion of the rotatable Locking element radially outwardly projecting arms consist. In the basic unit are preferably two in diagonal extension aligned locking arms intended. In a preferred embodiment that is Locking element, however, arranged with a cross shape Provided locking arms. This offers, for example the possibility that the containers to be stacked on each other even in a rotated position by 90 ° can be mounted, so that in a box-shaped Container, for example, the opening side not only after front, but also to the left, to the right or to Rear can be aligned arbitrarily. A disadvantageous Effect on the effectiveness of the locking device does not have this.

In a particularly preferred embodiment, the individual locking sections designed such that in the form of a passage opening in a cup-shaped Floor section of the respective locking element correspond and in a basic position equal to this Passage opening to come to rest. The whole Locking base portion is rotationally fixed in installed a furniture part. So that's with one equipped such locking element furniture part virtually closed in a continuous outer surface, there the locking arms of a locking element in height the passage opening come to rest, this opening thereby virtually covered.

In one embodiment of the invention is also a Spring device provided, which is the adjustable Locking or rotating part in its unlocked base or Starting position subjected to force. This ensures that that the locking arms in their Grundoder Starting position exactly in the plane of the passage opening in the cup-shaped bottom of a locking base portion to come to rest. This also has the advantage that in an unlocking process then - when the locking arms be rotated in the release position, where they congruent in this position to the passage opening in the cup-shaped bottom portion of a locking base come to rest - by the spring action the corresponding Locking element in its unlocked position is raised. In this position is yet another Clamping mechanism provided, which then the rotating part holds in this axial position.

In Figure 1 are in accordance with the schematic perspective Representation of three built on and fixed box-shaped or container-shaped pieces of furniture 1 shown.

In Figure 1 are building on two larger-sized Furniture pieces 1 shown, the depth of 3 and 5 height is dimensioned the same, the corresponding end face so it is square. The length 7 is twice as long as the height or depth. In the vertical side walls 1a is in the middle each one below in detail discussed locking device 9 installed. The the same applies to the opposite vertical side wall 1b. Similarly, in the lower floorboard 1c with the overhead deckboard 1d also locking devices 9 installed, and, since the floor board 1c and the deck board 1d are twice as large as the front side walls 1a and 1b, there are two locking devices 9 provided in the transverse direction of the rectangular Floor and cover boards are arranged in the middle and doing a longitudinal distance corresponding to half the length have these board-shaped wall elements, wherein the Distance from the center of a locking device 9 to the front End of the rectangular bottom a quarter of Total length of the board is.

Only to illustrate different possible construction variants is further shown that in Figure 1 above another container element 1 'is constructed, the only half the length to the lower lying container elements 1 and in the bottom board 1c as the cover board 1d only one centrally arranged locking device 9 has.

Already by this structure is apparent that each the built in a floor board 1 d locking device 9 in plan view immediately adjacent and congruent comes to lie to a respective locking device 9, in an underlying cover board 1d of a next box or container-shaped piece of furniture 1 is provided.

According to the illustrated embodiment, all mentioned Arretiereinrichtungen 9 functionally identical and doing preferably even formed identical, with two each mirrored to each other locking devices 9 cooperate and the locking device according to the invention form.

In the following, reference is made to FIGS. 2 and 3, wherein in Figure 2 in a schematic perspective view a locking device 9 rather overlooking the Top and in Figure 3 is a corresponding locking device 9 with a view rather to the bottom is, as well as two locking devices 9, for example at the point marked "A" in Figure 1 cooperate to an overhead floor board 1c with an underlying cover board 1d two furniture containers 1 firmly connected. As discussed below not only the two boards lie in use 1c and 1d along a common cultivation plane 11 to each other but also the two locking devices according to Figure 3 and Figure 4 touch with their bottom surfaces or are positioned only at a small distance. The two 3 and 4 locking devices 9 are shown in other words, according to the arrow 13 in FIG the cultivation direction characterized in contact or brought into direct contact. The said cultivation level 11 corresponds for example to a horizontal plane. Already From Figures 2 and 3 is thus apparent that each cooperating locking devices 9 from the basic structure cup-shaped, so a pot-shaped fixed part, Housing part or base part 15 include, which is a pot-shaped or cylindrical boundary wall 15a and a Floor 15b has.

In the embodiment shown, each locking device comprises 9 also has a peripheral edge or flange 15c, in the embodiment shown in the amount of the above lying pot opening 17, so opposite to the bottom Bottom 15b, comes to rest.

Each of the locking devices 9 has a total of one a circular shape deviating shaping in order to Shelf or floorboard ultimately installed against rotation to be able to. In the embodiment shown is the cylindrical boundary wall 15a of the cup-shaped lock 9 in itself not against rotation. However, that is formed on top flange-shaped edge 15c elliptical. According to the material thickness of this edge is an elliptical depression in the respective furniture board 1c or 1d next to a total of the board passing through incorporated cylindrical bore 19 so that after inserted Arretiereinrichtung 9 a rotation not is possible. Otherwise, for example, as well one or two of the flange-shaped edge 15c passing through Screwed 21 screws in the respective board 1c and 1d be to even with circular edge or flange 16c prevent twisting.

Incidentally, but could also be the cup-shaped design of Basic or fixed part 15 e.g. on the outer circumference one of a cylindrical cross section deviating shape have to drill in a correspondingly elaborated hole 19 by a shelf through a twist-proof Ensure fit. However, this is more complicated.

In Figure 4 is a schematic axial plan view and in Figure 5 is a schematic axial bottom view of the explained Locking device 9 shown. From Figure 5 is It can be seen that the disk-shaped bottom 15b of the locking device 9 has a cross-shaped recess 23. Starting from a central central axis line 25, is this recess 23 in the illustrated embodiment formed symmetrically so that the radially of the Central axis 25 outgoing arm-shaped opening areas 23 'same radial length and the same transverse to the radial direction have running width.

In the cup-shaped interior 27 of each locking device 9, i. in the cup-shaped interior 27 of the Base or fixed part 15 of a respective locking device 9, an adjusting member 29 is arranged, which Partially referred to below as a rotary member 29 becomes. This rotary member 29 comprises a cover cap-shaped Operating part 29a, one underneath and itself to the actuating member 29 a axially subsequent driver 29b and a arranged on the underside of the driver 29b Locking element 29c. The above sections 29a to 29c of the incision member thus formed or rotary member 29 are rotatably attached to each other. The thus formed rotary member 29 may also be integrally formed be. It is also possible that the driver 29b im small dimensions axially, i. telescopically extendable and retractable is, in other words, the axial length of the driver is adjustable.

The locking element 29c comprises in the illustrated embodiment starting from the central axis 25, four locking arms 31, by their design and their arrangement are again designed cross-shaped, so far the cross-shaped recess 23 correspond. Indeed is the width and length of these locking arms 31 designed that they are dimensioned correspondingly smaller, so that even in the normal position according to FIG. 3 or 5 these locking arms 31 surrounded by a circumferential gap 33 even if they are at the level of the bottom 15b in the Floor located recess 23 are arranged. Thereby a total of one game is scored, to which below will be received.

As is apparent from the cross-sectional representations according to FIGS. 6 ff. It can be seen in the interior 34 is still a spring device 35 provided on the one hand on the pot-shaped housing, i. at the bottom 15b of the base or Fixed portion 15, and on the other hand at the bottom of the cap-shaped Operating parts 29a supported. Since that Rotating part 29 captive in the cup-shaped housing part (hereinafter partly also referred to as fixed part 5) is held, the rotary member 29 is not made of the cup-shaped Reception room 34 are pushed out or fall out. These are, for example, at the height of the flange Edge 15c at least two, preferably several in Circumferentially offset projections or a circumferential closed stop edge 37 formed on which hit the cover cap-shaped operating part 29a would. The axial longitudinal extent of the rotatable Adjusting member or rotary member 29 is such that in the basic position according to Figure 6, the arm-shaped and radial projecting locking arms 31 at the level of the cruciform Recess 23 come to rest in the bottom 15b. The mentioned spring device 35 is tuned so that the biasing force of the spring on the rotary member 29 in the direction the overhead flange-shaped edge 16c adjusting forces exercises, but only so far, until the cap-shaped Operating part 29 a, the basic position shown in Figure 6 reached. In this basic position remains per se yet another axial adjustment, until the cover cap-shaped Operating part 29a on the upper edge 37 strikes. In the position shown in Figure 6 occur However, the at the peripheral edge of the cover cap-shaped operating part 29a trained one or more (in 9 indicated) projections 38 with the in the inner wall the cup-shaped central portion of the fixed part 15 recesses introduced in corresponding places in Interaction. This is also a pre-adjustment and Alignment of the cross-shaped locking arms 31 given since exactly in that position, the locking arms 31 in the same cross-shaped orientation can be brought in the also the cross-shaped recess 23 is aligned. The in the recess 43 in the peripheral wall 15a of the fixed part 15 engaging projections 38 additionally generate still a certain friction. Also this can by the spring force of the spring device 35 to the Insertion or rotation part 29 by the force of the spring alone not be further adjusted, as in FIG. 6 is shown.

The above-described structure also has the consequence that upon delivery appropriately designed container itself the cover cap-shaped cover 29 quasi at a small distance below the level surface of the outer boundary plane 1e of a corresponding wall of the box-shaped container located and also the opposite level surface 1f through the bottom and in the recess 23 in the Floor 15b seated locking element 19b virtually the entire surface is closed.

FIG. 7 essentially corresponds to the representation according to FIG FIG. 6, but with the difference that in FIG Rotary member or adjusting member 29 against the force of Federspeichereinrichtung 35 pressed in the direction of the bottom 15b is, so that the locking element 29 with the opposite Arretierarmen 31 over the surface of the bottom 15b pushed down to that position in which then the actual locking is made. Because the Sectional view according to Figure 6 and Figure 7 diagonal represented by the cross-shaped locking element 29c is, the total length of the locking elements 31 is only in Figure 7, but not in Figure 6, to see.

Are two containers according to Figure 1 in the same position each other set and should be fixed to each other, so come in accordance with the representation of Figure 8 two explained locking 9 directly congruent to lie to each other. The two are adjacent lying to Arretiereinrichtungen 9 mirror image aligned to its mean cultivation level 11, i.e. with their two floors lying on top of each other. The page, where the floors come to lie, represents the respective outside of a corresponding container, so that each comes from the inside of a container the cover cap-shaped actuating part 29a freely accessible lies.

To perform a locking of two furniture, is now in one of the two locking devices 9, for example at the top in Figure 8 locking device 9, the freely accessible cap-shaped Operating member 29 against the force of the spring accumulator 35 pressed. Since the two cross-shaped locking elements 29b of the upper and lower locking means 9 lie on each other, is now by pressing the overhead rotary member 29, the lower adjustment member 28 downwardly shifted axially or the lower Arretiereinrichtung 9 associated locking elements 29b by the telescopically extendable and retractable driver unit 29a so adjusted (if such a mechanism is provided), that with the upper actuating part 29a rotatably connected locking member 29c with his four radially projecting locking arms or fingers 31 in the interior 34 of the other shelf, i. in the lower shelf located fixed part 15 is located and immediately adjacent to the cup-shaped bottom 15c of the bottom in Figure 8 second locking device 9. Then it becomes the upper locking device 9 associated actuating part 29a axially rotated so are itself belonging to the overhead rotary member 29 Arretierarme 31 behind the remaining locking projections 41, through the remaining floor sections in the Floor 15b of the bottom in Figure 8 locking device 9 are formed. These locking projections 41 are the remaining material portions in the bottom 15b, respectively rotated in the direction of rotation about the central axis 25 to the cross-shaped recesses 23 are formed.

Since, as mentioned, the recess 23 larger dimensions is, as the movable here through locking elements 29c, and in other twisting or locking position the front ends of the locking elements 29b in the radial Distance in front of the cooperating boundary wall 15a of the base or fixed part 15 ends is a ensures sufficient compensation margin, for example Tolerance error in the fixed connection of to balance two containers.

Furthermore, the underside of these locking projections is preferred 41 of the bottom 15b and / or the adjacent Contact surface of the locking arms 31 in cross-section roof-shaped designed so that with increasing twisting motion from the neutral starting position one increasingly greater clamping action between the adjusting member 28 of a locking device 9 and the corresponding locking projections 41 in the bottom 15b of each cooperating therewith second locking device 9 sets.

From Figure 9 which are slightly roof-shaped in cross section designed or with a preferred middle radial extending slightly rib-shaped elevation 42 provided Arretierarme 31 can be seen, in Figure 10 is a plan view on the empty cup-shaped housing or fixed part 15th reproduced without inserted adjusting member or rotary member 29 is, so that is particularly well the appropriate slightly groove-shaped recess 43 can be seen. Thereby results in a bayonet-type locking mechanism, namely, if in the final locked position, for example slightly ribbed or gabled Elevations or projections 42 on a respective locking arm 31 then into the corresponding recesses 43 on the inside of the bottom 15b of the pot-shaped housing cover 9a of the respective second locking device engage. Since the rotating part with a rotational movement supporting Gripping rib 45 or a gripping projection 45 can be provided by the orientation of this gripping projection 45 can be read directly, whether a lock setting has been made or not.

Finally, on the inside of the peripheral wall 15a the cup-shaped housing part 9a also still vertical recesses or vertical projections to be formed, the with corresponding vertical projections or vertical Recesses on the outer circumference of the cover cap-shaped rotary member 29 and thus also still the support bayonet-type locking mechanism. Thereby will also be for the interlocking person immediately felt when the adjusting member 28 the final locking position has reached.

The embodiment has been explained for that case that the recess 23 in the bottom 15c is cross-shaped and also the locking arms 31 corresponding cross-shaped are designed. In principle, it would also be conceivable that the recesses as the locking arms only diagnonal or bar-shaped.

Likewise, instead of the explained spiral Spring device 35 and preferably made of plastic formed pot-shaped housing part 15 elastically deformable be casted inside plastic arms, the the desired biasing forces on the adjusting member 29th exercise.

A release can be made just as easy again be like the lock. Exactly that rotary part 29, which has been used for the lock is Turned back or twisted until, again the locking arms 31 in the correct position to the cross-shaped Passage opening 23 in the two superimposed Soils 15b come to rest. Through the support of the Spring force storage is then the depressed rotating part moved back into its raised position in Figure 6 position.

Through the roof-shaped ramp surfaces on the locking arms 31 or by otherwise oblique or wedge-shaped Run-up surfaces can with increasing twisting movement an increasingly stronger, axially facing each other Tensioning force between the two cooperating locking devices 9 are generated. Each of the two Locking devices 9 is at the associated Furniture, for example on a floor board 1c and an underlying deckboard 1c firmly anchored. Since in each case the flange-shaped circumferential edge 15 c on the to lie opposite the inside of the container can, even with progressively greater convergence directed locking forces none of the two locking devices from their hole in the associated shelf be pulled out. Each of the two locking devices 9 is thereby by the flange-shaped edge held on the associated shelf.
