Description

Holding device for a shelf on a shelf wall and shelf with such a holding device

The invention relates to a holding device for a shelf on a shelf wall, a connecting element according to the preamble of claim 12, a shelf according to the preamble of claim 13, and the use of the holding device in a piece of furniture according to claim 16.

From the state of the art it is known to secure the shelves on shelves in the shelves by means of connecting elements in the form of protruding holding pins made of metal or plastic. The support pins of a shelf are inserted into holes on the insides of the shelf walls to a part, so that the protruding part of each retaining pin can serve as a support for the shelf. In order to adjust the height of a particular shelf, a plurality of holes for receiving retaining pins on the insides of the shelf walls are provided. In this way, the height of a shelf can be adjusted by first all the holding pins of a shelf at the same height are inserted into the corresponding holes of the shelf walls and then the shelf is placed on these retaining pins. The disadvantage of this, however, is that several steps are required to adjust the height of a shelf, which has a corresponding amount of time result. In addition, the aesthetic impression is reduced by the unused holes in the shelf walls, or there is a risk of injury when retaining pins from these holes protrude freely.

From JP 2009 160033 A, a holding device for a shelf on a shelf wall with a arranged on the shelf wall first connecting element and arranged in the shelf second connecting element is known. The second connecting element has an attracting to a holding element of the first connecting element acting magnet to move the holding element of the first connecting element magnetically along a pull-out direction from a retracted retracted position to an extended holding position for supporting the shelf to the shelf wall. By a arranged on the underside of the support member bevel the holding element is manually pressed in a lifting of the shelf in the retracted position. However, this can lead to tilting of the retaining element, whereby the release of the Shelf is made difficult. In addition, the slope of the retaining element in the retracted position forms a visually clear perceptible recess on the inside of the shelf wall, in which dirt can penetrate particularly easily, whereby the holding element can additionally jamming.

The object of the invention is therefore to enable a simple and quick release of the shelves of the shelf wall. In addition, a secure positioning of the shelves and an aesthetically pleasing shelf wall to be created. The holding device should also be used in furniture pieces for holding appropriate furniture parts.

This object is achieved by a holding device with the features of claim 1, a connecting element with the features of claim 12, a shelf with the features of claim 13 and the use of such a holding device in a piece of furniture according to claim 16. Advantageous embodiments of the invention are specified in the subclaims.

The holding device according to the invention for a shelf on a shelf wall is characterized in that the first connecting element comprises a housing and a spring element arranged in the housing, which holds the holding element in the retracted retracted position in the housing and on the one hand at an area with an enlarged cross section of Supporting element and on the other hand supported on an area with reduced cross section of the housing. By the spring element, the holding element is automatically moved to the retracted retracted position and held there. This ensures that the retaining element securely remains in the retracted position, as long as this does not affect a magnetic force through the second connecting element.

By supporting the spring element on the one hand on the region of enlarged cross section of the holding element and on the other hand on the area with reduced cross section of the housing a direct transfer of the spring force and thus a low Verklemmneigung and a space-saving design can be achieved.

Due to the magnetic attraction between the connecting elements, the holding element of the first connecting element is automatically extended into the holding position, as soon as the connecting elements come into magnetically effective proximity, so that no additional step is required for this. If a plurality of first connecting elements are provided at different heights in the rack walls, then only those holding elements in the immediate vicinity of which there is a shelf with corresponding second connecting elements are in the extended holding position. The holding elements of the remaining first connecting elements are due to the action of the spring element in the retracted retracted position, which avoids injuries and allows an aesthetic impression of the inside of the shelf walls. The spring element can be dimensioned so that in the retracted retracted position of the retaining element, the spring element is enstpannt. Only when the retaining element is moved out of this retreat position, the spring element is biased. This ensures that the magnetic force to move the retaining element can be extremely low. However, it is also possible to design the spring element so that it is biased in the retracted position of the holding element, resulting in a particularly good assurance of the holding element in this position. In addition, the spring element in addition to the usual spiral design made of metal or plastic and a foam with appropriate stretch or compressibility consist, for example, a hollow cylinder or a spiral of foam.

The region of increased cross-section of the retaining element prevents the retaining element unintentionally detached from the first connecting element and falling out of the shelf wall. Depending on the configuration of the retaining element, the region with increased cross-section can be arranged centrally or at a rear end opposite the protruding end of the retaining element. The holding element can be designed so that it protrudes in the extended holding position only on an inner side of the respective shelf wall. This is the case, for example, with the outer shelf walls of a shelf. Then, the area of the enlarged cross section is located at the rear end. However, if additional intermediate walls are arranged on a shelf between these outer shelf walls, corresponding first connecting elements are to be provided on both sides in these intermediate walls, but this can be achieved particularly advantageously by arranging the holding element of each first connecting element in a through hole in the intermediate wall, that it is made from both side surfaces of the intermediate wall can stand out. In this case, the region of the enlarged cross section is preferably arranged centrally on the holding element.

The region of reduced cross-section may preferably form a first guide section of the housing, the inner contour of which is slightly larger than an opposite outer contour of a holding section of the holding element, and a second guide section of the housing has an inner contour which is slightly larger than the opposite outer contour of the enlarged section Cross section of the retaining element. As a result, the guidance of the retaining element in the housing can be improved, since the risk of tilting is reduced by the two guide sections in the housing. In addition, an enlarged support surface is achieved, whereby particularly high weight forces of shelf with the second connecting element via the retaining element in the first connecting element and thus the shelf wall can be initiated.

As a slightly larger or smaller is to be understood in this sense that between the inner contour of the first guide portion and the opposite outer contour of the holding portion or between the inner contour of the second guide portion and the opposite outer contour of the region with an enlarged cross-section of the holding element usual for a guide Game is present, which is usually fractions of a millimeter. As a result of this slight play, in particular between the first guide section, which is arranged on a front end of the housing of the first connecting element facing the second connecting element, and the holding section of the retaining element, the penetration of dirt into the housing of the first connecting element is prevented. As a result, the leadership of the support member is not affected for a long time by accumulating in the housing dirt.

The cross-section of the inner contour of the first and / or second guide portion of the housing and the corresponding cross-section of the outer contour of the holding portion and the region of enlarged cross-section of the holding member may be formed in addition to circular also, for example, rectangular. This design of the retaining element allows a bearing surface which is larger than a round cross-section, whereby the surface pressure between the retaining element and the housing decreases. There is also a such cross-section also secured against rotation, so that a defined orientation of the retaining element is ensured on the housing.

In an advantageous embodiment, the housing between the first guide portion and the second guide portion having a first limiting element for defining the extended holding position of the holding element. The inner contour of the first delimiting element is larger than the inner contour of the first guide section, that is to say the area of reduced cross section of the housing, and smaller than the outer contour of the area of enlarged cross section of the retaining element. If the holding element is pulled by the magnet in the direction of the second connecting element, the region of enlarged cross-section of the holding element comes to rest on the first limiting element, whereby the extended holding position of the holding element is structurally predetermined. Without this first limiting element, the spring element, which is arranged between the region of increased cross-section of the holding element and the region of reduced cross section of the housing and is supported there, could be compressed in an inadmissible way over the maximum compression away, whereby the spring element would be damaged. Due to the defined extended holding position, the projection of the retaining element from the housing of the first connecting element is also exactly predetermined, which is advantageous for the connection to the second connecting element, as will be described below.

In a particularly preferred embodiment, the first limiting element may be formed as an annular web surrounding the spring element. This ring land may have a rectangular cross section or a round cross section. However, it is also possible for the first limiting element to be formed by a stop part, which extends only in sections in the circumferential direction, for the retaining element.

In order to define the retracted retraction position of the retaining element, in an advantageous embodiment the housing can have a second limiting element in the region of the second guide section at a rear end facing away from the second connecting element. The second limiting element can protrude inwards relative to the second guide section and thus form a rear stop for the retaining element in the retracted retracted position. This second limiting element may preferably be used as a locking means with an elastic be formed hook-shaped element in the form of a latching nose, whereby in particular the pre-assembly of the holding element is facilitated in the housing. For this purpose, provision may be made for the housing to have an opening at a rear end remote from the second connecting element, through which the holding element can be inserted into the housing and in particular into the first and second guide section of the housing. During pre-assembly, the hook-shaped element is pressed by the holding element elastically outwards until the holding element is arranged in the housing and the hook-shaped element springs back elastically. In an advantageous embodiment, the holding element at a front end facing the shelf may have at an angle to the extension direction protruding locking element to fix the connecting elements positively against each other in the extended holding position by engaging behind a corresponding undercut on the shelf to be arranged in the second connecting element. The blocking element may also have the largest cross section in the region of its free end. In this way, the locking element in the extended holding position engage behind a corresponding undercut on the shelf and thus secure the first connecting element to the shelf. In addition to the magnetic attraction between the connecting elements so that additionally held by the blocking element, the first connecting element in the extended holding position, which increases security. In this case, the region of the free end of the retaining element is preferably that region which protrudes from the shelf wall in the extended holding position of the retaining element.

In a further advantageous embodiment, the second connection element can have a recess open towards the first connection element with an undercut for the positive reception of the blocking element. The undercut is advantageously oriented in the vertical direction, so that the blocking element is first inserted horizontally into the receptacle and then vertically upwards into the undercut. However, it is also possible to align the undercut at an acute angle to the horizontal, in principle, only an undercut in the horizontal direction is advantageous. Through this undercut, a positive connection of the second connecting element with the holding element and thus the first connecting element is achieved. This has the consequence that the relevant shelf wall even at higher load The shelves can not deform away from the shelves laterally outward, whereby the load and the stability of the shelf are additionally increased.

The depth of the undercut, viewed in the extension direction of the retaining element, preferably corresponds to the projection of the locking element relative to the front, the second connecting element facing the end of the housing of the first connecting element in the extended holding position. In this case, the relationship applies that the depth of the undercut corresponds to the distance of the blocking element from the region of increased cross-section of the holding element minus the distance of the first limiting element from the front end of the housing.

It can also be provided that reduces the depth of the recess in the extension direction, starting from the undercut down. The reduction of the depth is preferably carried out in the vertical direction gradually down to zero, ie in particular without steps or edges. By this elongated undercut, the retaining element can be pressed in a removal of the shelf in the vertical direction by the reducing depth of the recess back into the retracted retracted position, whereby the effect of the spring element is supported. The magnet can preferably be arranged in the second connecting element, in particular in a holder, adjacent to the undercut and held there in a positive and / or frictional engagement. Particularly advantageously, the magnet is positioned in the extended direction of the retaining element from the retracted retracted position to the extended holding position behind the undercut. This results in a particularly favorable magnetic force by the magnet on the holding element in the direction of the distinction. Particularly preferably, a stop on the second connecting element, in particular the holder, be provided between the magnet and the undercut. By the stop the minimum distance between the magnet and a arranged in the undercut blocking element and thus the maximum mutual magnetic attraction is precisely determined. In addition, the stop prevents that the magnet can move in the direction of the undercut, so that it remains reliably free undercut and also the magnet can not escape from the connecting element and in particular the holder. The retaining element may be formed as a preferably elongated retaining pin and the spring element as a spiral extending around the retaining element compression spring. However, it is also possible to carry out the spring element as a tension spring, which is connected on the one hand with the holding element and on the other hand with the rear, the second connecting element remote from the end of the housing of the first connecting element in order to pull the retaining element in the retracted retracted position. But it is also possible to carry out the holding element, for example, as an elongated strip with a rectangular cross-section, whereby a particularly large-scale power transmission between the shelf and the shelf wall is made possible. Other configurations of the retaining element, for example with different cross sections or thicknesses are possible. In addition, the spring element may also have a rectangular cross-section corresponding to the holding element.

In addition, a connecting element is claimed, which is designed for placement in a shelf of a shelf and for holding interaction with a arranged in a shelf wall of the shelf further connection element, wherein it is open to the further connection element recess with an undercut for the positive reception of a locking element of having another connecting element. The connecting element may also preferably have the further features of the second connecting element of the described holding device.

According to the invention, a shelf has at least one holding device described above and below as well as at least two shelf walls and at least one shelf. In this case, the second connecting element of the holding device is arranged on a shelf wall facing one end of the shelves and the first connecting element of the holding device in the corresponding shelf wall opposite the second connecting element. In such a shelf, the adjustment of the height of a shelf can be done quickly and easily, since the holding elements of the respective first connecting element is automatically moved by the corresponding shelf in the extended holding position. The holding elements of the first fasteners not used for supporting a shelf are still in the retracted retracted position, whereby the risk of injury is reduced by protruding holding elements and the aesthetic impression is promoted. It may be advantageous to arrange the first connecting element in the shelf wall such that the holding element is movable substantially in a horizontal plane between the holding position and the retracted position. In the case of the mostly vertical shelf walls, therefore, vertical recesses are to be provided in the shelf walls for receiving the connecting elements, which are easy to manufacture. In this case, the holding element of the first connecting element can also be moved without the influence of gravity. However, it may also be advantageous to use the force of gravity on the retaining element such that it is thereby held in the retracted retracted position. For this purpose, the first connecting element is to be arranged in the shelf wall, that the holding element is arranged higher in the holding position than in the retracted position. This is achieved in that the recess for the first connecting element relative to the shelf wall has an acute angle, which can be achieved for example by oblique holes. In order to facilitate the positioning of the shelf on the two opposite shelf walls and to improve the stability of the shelf, it can also be provided that the shelf or the side walls of a shelf box, which are attached to the shelf at the lateral ends and parallel to extend the shelf walls, at least one additional magnetic element having, which corresponds in the installed position of the shelf or the shelf box between the shelf walls with at least one additional additional magnetic element in one of the shelf walls, in particular correspondingly positioned opposite each other, so that these magnetically acting Attraction. When mounting such a shelf or such a shelf box, these additional magnetic elements come in magnetically effective proximity to each other and support the exact positioning of the shelf or the shelf box between the shelf walls by the increasingly strong with reducing the distance between them magnetic force. As a result, the shelf or the shelf box can be easily and quickly brought into its correct position between the shelf walls, whereby the connecting elements are positioned more easily to each other and thus the automatic extension of the holding elements is facilitated. In addition, these additional magnetic elements connect the shelf or the side walls of a shelf box with the shelf walls in the horizontal direction, whereby the cohesion of these components is enhanced. Instead of directly opposing additional magnetic elements, it can also be provided that the additional magnetic elements in the shelf or the side walls of a shelf box and the shelf wall are vertically offset from each other so that the additional magnetic element in the shelf or the shelf box in the installed position of the shelf or the shelf box, so if the shelf or the shelf box are supported by the holding device, is arranged slightly above the other additional magnetic element in the shelf wall in the vertical direction. This results in a force acting in the vertical direction magnetic force between the additional magnetic elements, which causes an additional, acting in the vertical direction downward force on the shelf or the Regalbox against the holding device. As a result, the contact pressure of the shelf or the shelf box is increased to the holding device and in particular the holding element, which increases the stability of the shelf. It can also be provided that the additional magnetic element in the shelf or the shelf box is formed integrally with the magnetically executed second connecting element. This combined magnetic element would then be advantageous to arrange so that the magnetic force acts substantially horizontally, so that both the additional additional magnetic element in the shelf wall and the first connecting element in magnetically effective range come, so that on the one hand between the combined magnetic element and the the first connecting member acts a sufficient force for extending the holding member of the first connecting member and on the other hand causes the magnetic force between the combined magnetic element and the further additional magnetic element, the positioning and pressing force described above. In order to minimize unwanted influence of the retaining element by the additional additional magnetic element in the shelf wall, the retaining element may be magnetically formed only at its outer, for example, cylindrical with a smaller diameter end. Alternatively or additionally, the additional additional magnetic element can also be made significantly smaller, in particular have a smaller diameter. This can also be used in the embodiments described above and below.

In order to position the shelf or the shelf box in a clear, predetermined position between the shelf walls easier and avoid incorrect positioning To be able to, for example, that the shelf or the shelf box are installed rotated 180 ° about the vertical axis, it can be provided that, for example, the additional magnetic elements in the shelf or the shelf box and in the shelf walls in a side view of the shelf or the shelf box are arranged asymmetrically or only one side corresponding magnetic elements in the shelf or the shelf box and the shelf wall are arranged. In case of incorrect installation of the shelf or the shelf box between the shelf walls then acts due to the large distance between the corresponding additional magnetic elements no sufficient magnetic force, whereupon the user detects the missing positioning aid and repositioning. In addition to this installation aid, the holding devices and the additional magnets can also be installed rotationally symmetrical. This means that the first connecting elements are arranged offset on one side of the shelf with the corresponding second connecting elements in the shelf wall in a longitudinal direction of the shelf adjacent to the shelf wall of the shelf and the first connecting elements on the other side of the shelf with the corresponding second connecting elements in the opposite shelf wall are arranged offset in the opposite direction by the same distance. In the plan view of a shelf, therefore, the first connecting elements and thus also the corresponding second connecting elements, starting from an arrangement in which the connecting elements are arranged symmetrically to a central axis arranged in the longitudinal direction of the shelf, on both sides by the same distance, but in opposite Directions along the end faces of the shelf moved. Such a trained shelf is so far rotationally symmetrical in that although the first connecting elements to a centrally located between the end faces of the shelf transverse axis are not symmetrical, with a rotation of a shelf about a vertical axis by 180 °, the positioning of the connecting elements is identical, so that Also in this orientation, an assembly of the shelf in the shelf is possible.

The reason for this rotationally symmetrical arrangement of the connecting elements is that the first connecting elements can extend far into the shelf wall, however, especially in partitions of a shelf in which corresponding shelves are arranged on both sides, the wall thickness of the partition wall can be too low to arrange two first connecting means for each side of the partition coaxially exactly behind one another. To get a flat arrangement of shelves on both sides of the To allow partition at the same height, the first connecting elements on one side of the partition wall with respect to the first connecting elements on the other side of the partition as described can be offset uniformly rotationally symmetrical. The corresponding second connecting elements on the corresponding side of the partition and the opposite shelf wall are then also arranged offset uniformly rotationally symmetrical.

In order to additionally facilitate the actuation of the retaining element, the retaining element may consist of a material which is light but nevertheless magnetically active in comparison to steel and / or hollow or perforated. As a result, the inertia of the holding element can be reduced without thereby appreciably reducing the magnetic force on the holding element. So it is sufficient already a lower magnetic force to bring the holding element in its extended holding position. The holding element can also be formed as a whole or only partially, for example only the tip of the holding element, as a magnet. Such a holding element can be produced for example as a magnet by injection molding. In addition, a corresponding bar magnet can be inserted or pressed into an inner recess of a hollow holding element. If the material of the holding element or at least of the blocking element consists of a magnetic active material, a magnet, for example a disc magnet, can be arranged at the rear region with an enlarged cross-section of the holding element, whereby the remaining part and in particular also the blocking element is magnetized. With such a magnetized holding element can be dispensed with in an advantageous manner to the above-described additional magnets, in which case, however, in addition to the parallel arrangement, the central axis of the magnet in the holder or the second connecting element is offset vertically to the central axis of the holding element so that the central axis of the magnet is higher than the center axis of the holding member to ensure a vertical contact pressure.

According to the invention, it is also provided to use the described holding device for holding corresponding furniture parts in a piece of furniture. These furniture parts can be trays of any kind, for example, floors in a desk, in a cabinet to a slatted base in a bed frame. Other features and advantages of the invention will become apparent from the following description of preferred embodiments with reference to the drawings. Show it:

Figure 1 shows a sectional view of a first embodiment of the holding device 1 according to the invention used in a shelf 2 and an adjacent shelf wall 3 of a shelf only partially shown. This relative position of the shelf 2 to the shelf wall 3 illustrates the situation in which the shelf 2 was inserted into the shelf and is held by the holding device 1 on the shelf wall 3. The holding device 1 according to the invention comprises a first connecting element 4 and a second connecting element 5. The second connecting element 5 is designed as a magnet and inserted from below on the shelf wall 3 facing the end of the shelf 2 flush in a recess in the shelf 2.

In the shelf wall 3, the first connecting element 4 is arranged in a bore formed as a lateral recess 6. This comprises a holding element 7 in the form of an elongate retaining pin, a spring element 8 designed as a spiral spring and a housing 9, in which the retaining element 7 and the spring element 8 are arranged. The holding element 7 consists wholly or partly of a magnetically active, that is attractable material, such as steel, iron, etc. The housing 9 is formed as a socket in which the holding element 7 is received and guided. To attach the housing 9 in the shelf wall 3 is provided to fix it via an adhesive connection, a press connection, a threaded connection or the like flush with the side surface of the shelf wall 3 in the recess 6. The holding element 7 is designed to be movable relative to the housing 9. The recess 6 preferably corresponds in depth to at least the length of the retaining element 7, so that the retaining element 7 terminates in a retracted retracted position with its outer, facing in the direction of the shelf 2 flush with the side surface of the shelf wall 3, in any case not beyond it , Since in this retracted position no part protrudes and the impression of a closed side surface of the shelf wall 3 is mediated, there is no risk of injury and there is an aesthetically pleasing uninterrupted side surface of the shelf wall 3. Ggf. For example, at the end pointing in the direction of the shelf 2, the housing 9 may also have a flange in the form of a circumferential annular web extending radially outwards. This flange forms a stop during the pressing of the housing. 9 In the latter case, the retaining element 7 at its front end facing the shelf 2 has a region with an enlarged cross-section, which preferably the cross-section of the flange corresponds. As a result, in the retracted retracted position of the retaining element 7 visually appealing only one visible edge is present and also the penetration of dirt into the housing 9 is particularly well prevented.

The housing 9 has a first guide section 10, which is formed on an end of the housing 9 facing the second connecting element 5, and a second guide section 11, which adjoins the first guide section 10. At the end of the holding element 7 which points into the recess 6, an area with an enlarged cross section 12 is formed, to which a holding section 13 adjoins. The guide sections 10, 11, the area with enlarged cross section 12 and the holding section 13 each have a constant cross section over the length, but also conical or continuously variable cross sections are conceivable. In this case, the diameter of the region with an enlarged cross section 12 is greater than the inner diameter of the first guide section 10, so that the holding element 7 can not pass completely through the first guide section 10 in the direction of the second connecting element 5 and fall out of the housing 9.

Between the first guide portion 10 of the housing 9 and the region with an enlarged cross-section 12 of the holding element 7, the spring element 8 designed as a spiral spring is arranged around the holding element 7. In this case, the spring element 8 is biased with one end to the region of enlarged cross-section 12 of the support member 7 and at the other end to the first guide portion 10 of the housing 9, so that the holding member 7 of the first connecting element 4 is pressed into the retracted retracted position. Due to the proximity of the second connecting element 5 designed as a magnet to the first connecting element 4, however, a magnetic force between the connecting elements 4, 5, which is greater than the retaining force by the spring element 8, so that the holding element 7 is pulled out in the extension direction X and this is in the extended holding position. In this holding position, the holding element 7 by the magnet of the second connecting element 5 against the action of the spring element 8 is acted upon, whereby the holding element 7 protrudes from the side surface of the shelf wall 3 and forms a support for the shelf 2. The housing 9 of the first connecting element 4 extends over the entire length of the recess 6 in the shelf wall 3. The first guide section 10 has an inner contour which essentially corresponds to the outer contour of the opposite holding section 13 of the holding element 7. The second guide section has a larger inner contour on the other hand, which substantially corresponds to the outer contour of the opposite region with an enlarged cross section 12 of the retaining element 7. In essence, in this context means that in each case there is a slight gap between the opposite sections, which allows a free relative movement between the holding member 7 and the housing 9. This ensures that the housing 9 can receive and guide the retaining element 7.

Due to the tight dimensional tolerances with which the housing 9 can be made, and a suitable choice of material for the housing 9, for example plastic or metal, which allows compared to a for example made of wood materials shelf wall 3 much more precise manufacturing and low friction coefficients, tilting the holding member 7 reliably prevented and the operation of the holding member 7 between the retracted retracted position and the extended holding position can be further improved. The housing 9 is formed as a cylindrical sleeve, wherein the second guide portion 11 with the enlarged inner contour, here inner diameter, by a blind hole and the first guide portion 10 through the blind hole bottom with a bore with a smaller inner contour, here inner diameter of the bore formed. The outer contour of the housing 9 is cylindrical and substantially corresponds to the inner contour of the recess 6 in the shelf wall 3. To attach the housing 9 in the shelf wall 3 is provided, that via an adhesive connection, a press connection, a threaded connection or the like flush with the side surface to attach the shelf wall 3 in the recess 6. Instead of the circular contours or cross sections, other contours or cross sections may advantageously also be used, for example polygonal, in particular triangular, quadrangular, hexagonal or octagonal internal and external contours. FIG. 2 shows a sectional view of a second embodiment of the holding device 1 according to the invention. In contrast to the first embodiment, the second connection means 5 comprises, in addition to a magnet 14, a holder 15 in which the magnet 14 is arranged. The second connecting element 5 is arranged on a lower, the shelf wall 3 facing edge of the shelf 2. The holder 15 of the second connecting element 5 has a recess 16, which is open laterally in the direction of the first connecting element 4 and downwards, with an undercut 17. The undercut 17 extends from the recess 16 in the vertical direction upwards. However, it is also possible to arrange the second connecting element 5 in the shelf wall 3 facing end side of the shelf 2, wherein the corresponding recess in the shelf can be incorporated either directly into the front page, which in particular the bottom of the shelf 2 undergoes no processing and therefore a visually appealing, or as shown in Figure 2, the corresponding recess can be incorporated from the bottom of the shelf in the front page, the recess, however, further vertically extends upward, so that the underside of the second connecting element 5 are provided with a corresponding cover can, which is flush with the bottom of the shelf 2 and forms a visually appealing underside. In this case, this cover has a recess which continues the recess 16 in the vertical direction, so that the retaining element 7 can enter the recess 16 unhindered.

Notwithstanding the following illustrations, the holder 15 also has a securing element 18, by means of which the magnet 14 is fixed in a receptacle 19 in the holder 15. The securing element 18 is designed as an elastic hook-shaped latching nose, which allows a simple pre-assembly of the magnet 14 in the holder 15. If the magnet 14 is inserted during the pre-assembly of the second connecting element 5 through an opening in the holder 15 in the receptacle 19, the securing element 18 is laterally deflected upward elastically and then springs when the magnet 14 is completely arranged in the receptacle 19 of the holder 15 is, back to fix the magnet 14 positively in the receptacle 19. As a result, a pre-assembly of the magnet 14 in the Holder 15 allows and prevents that the magnet 14 dissolves in the storage of the second connecting element 5 or during assembly in the shelf 2 of the holder 15. In addition to slightly different proportions, the holding element 7 also differs from the embodiment shown in FIG. 1 in that the holding element 7 has a blocking element 20 projecting at an angle to the extension direction X of the holding element 7 at a front end facing the second connecting element 5. The blocking element 20 is oriented at right angles to the extension direction X of the holding element 7, thus forming a vertical projection to allow in the extended holding position by engaging behind the undercut 17 a releasable positive connection with the second connecting element 5. By this rear grip of the retaining element 7 on the shelf 2, an unintentional movement of the retaining element 7 is prevented in the extended holding position, thus achieving a positive, particularly secure fixation of the retaining element 7 in this position. In particular, an uncontrolled release of the shelf 2 of the shelf wall 3 is thus reliably prevented, which increases the horizontal stability.

The outer diameter of the locking element 20 may correspond to at least the outer diameter of the housing 9 in an embodiment not shown, or be greater than this. In this case, the housing 9 is sunk in the shelf wall 3, that the locking element 20 is flush in the retracted position of the support member 7 flush with the side surface of the shelf wall 3, the locking element 20 covers the housing 9, resulting in an aesthetically beautiful side surface of the shelf wall. 3 yields and the penetration of dirt into the first connecting element 4 is reliably prevented.

In addition, can be effected by a likewise not shown embodiment of the locking element 20 together with the undercut 17, an additional force on the retaining element 7 in the direction of the extended holding position, ie in the extension direction X. For this purpose, the contact surfaces between the blocking element 20 and the undercut 17 are formed at an acute angle to a horizontal plane, so that the holding element 7 is pulled by the weight of the shelf 2 in the extended holding position. As a result, the required magnetic force of the magnet 14 of the second connecting element 5 can be chosen lower, and it is still a safe Holder of the shelf 2 reaches the shelf wall 3. If the blocking element 20 also has a rectangular cross-section, this results in an enlarged bearing surface with respect to the shelf 2 and thus also a higher additional pull-out force on the holding element 7. For this purpose, reference is made in full to the application EP 2 944 224 and its disclosure.

Compared with the embodiment shown in FIG. 1, the housing 9 of the first connecting element 4 between the first guide section 10 and the second guide section 11 additionally has a first limiting element 21 in the form of an annular web which controls the movement of the retaining element 7 in the extension direction X, ie in the direction from the retracted retracted position to the extended stop position. In the extended holding position, the region with an enlarged cross-section 12 of the holding element 7 abuts against this limiting element 21. The inner contour of the first delimiting element 21 is larger than the inner contour of the first guide section 10, that is to say the area of reduced cross section of the housing 9, and smaller than the outer contour of the area of enlarged cross section 12 of the holding element 7. The inner contour of the delimiting element 21 is formed in this way in that a gap is formed between the delimiting element 21 and the holding section 13, in which the spring element 8 is arranged. A contact surface for the spring element 8 on the first guide portion 10 is spaced from a stop surface on the first limiting element 21 for the region of increased cross-section 12 of the support member 7 in the extension X of the support member 7 such that the distance is slightly greater than the length of the maximum compressed spring element 8 is. Without this first limiting element 21, the spring element 8 could be compressed in an inadmissible way over the maximum compression time, whereby the spring element 8 would be damaged. In addition, the supernatant of the holding element 7 and in particular of the blocking element 20 out of the housing 9 in the direction of the second connecting element 5 is predetermined exactly and reproducibly by the first limiting element 21. Furthermore, the housing 9 of the first connecting element 4 has a second limiting element 22 in the region of the second guide section 11 on a rear end facing away from the second connecting element 5. The second limiting element 22 protrudes inwards relative to the second guide section 11 and thus forms a rear stop for the retaining element 7 in the retracted retracted position. The second Delimiting element 22 is designed as a latching nose with an elastic hook-shaped element, whereby in particular the pre-assembly of the holding element 7 in the housing 9 is facilitated. Through an opening of the housing 9 at a rear end remote from the second connecting element 5, the holding element 7 can be inserted into the housing 9 and in particular into the guide section 10, 11 of the housing 9. During pre-assembly, the locking lug is pressed by the retaining element 7 elastically outwards until the retaining element 7 is arranged in the housing 9 and the locking lug springs back elastically. In the position of the shelf 2 shown in Figure 2 to the shelf wall 3 of the shelf 2 is still so far away from the shelf wall 3 that no or only a very small magnetic force from the magnet 14 of the second connecting element 5 on the holding element 7 of the first Connecting element 4 takes place. Since the force acting on the retaining element 7 by the spring element 8 restoring force in the retracted retracted position is significantly greater, the holding element 7 is held in the retracted retracted position. The spring element 8 can also be dimensioned so that in the retracted retraction position no spring force acts on the retaining element 7, so no bias is applied. In this case, the magnet in the illustrated arrangement is still too far away, so that no magnetic force acts.

In the sectional view through the holding device 1 shown in FIG. 3, the shelf 2 is arranged closer to the shelf wall 3 than in the arrangement shown in FIG. In this intermediate step for fastening the shelf 2 to the shelf wall 3, the shelf 2 is not at all or only slightly spaced from the shelf wall, however, the shelf with the second connecting element 5 in the vertical direction is slightly higher than the first connecting element 4 positioned. In this arrangement, the magnetic force of the magnet 14 causes the holding member 7 is moved against the force of the spring element 8 from the retracted retracted position in the direction of the extended holding position. In FIG. 3, the holding element 7 of the first connecting element 4 is moved to a part in the direction of the extended holding position, so that in particular the blocking element 20 projects out of the side surface of the shelf wall 3.

The second connecting element 5 is arranged opposite the first connecting element 4 such that the recess 16 in the holder 15, the blocking element 20 of the Holding element 7 in the extension direction X is opposite and thus the blocking element 20 can be pulled into the recess 16. By arranged in the extension direction X behind the recess 16 in the holder 15 magnets 14, the holding member 7 is pulled straight and at a short distance magnetically in the direction of the recess 16. To ensure easy mounting of the shelves on the shelf wall by means of the holding devices, all forces, ie in particular the spring force of the spring element 8 and the magnetic force of the magnet 14, in such a way to the distances, in particular the installation depth of the magnet 14 in the shelf 2 and the Size of the recess 16 in the horizontal direction to adjust that even with still existing small distance of the shelf 2 of the shelf wall 3 in a conventional mounting of the shelf 2 from above, the spring force is overcome so early by the magnet 14 that the holding element 7 from his Retraction position is pulled before he can drive into the undercut 17. This results in no jamming of the elements, but it is a pleasant and frictionless assembly process allows.

FIG. 4 shows a sectional view through the holding device 1 in an arrangement in which the shelf 2 is connected in a form-fitting manner to the shelf wall by means of the holding device 1. The shelf 2 lies with his facing to the shelf wall 3 side surface of the shelf wall 3. Compared with the arrangement shown in Figure 3, the shelf 2 was moved together with the second connecting element 5 also relative to the shelf wall 3 with the first connecting element 4 down, so that the blocking element 20 with the vertically upstanding part in the undercut 17 in the Holder 15 engages and thus the connecting elements 4, 5 are fixed in the horizontal direction positively against each other.

In this extended holding position of the holding element 7, the region with an enlarged cross-section 12 abuts directly against the first limiting element 21. The spring element 8 is arranged and compressed in the gap between the first delimiting element 21 and the holding section 13 of the holding element 7. In order to enable a substantially backlash-free attachment of the shelf 2 to the shelf wall 3, while the blocking element 20 stands exactly so far on the housing 9 and thus the shelf wall 3 in the direction of the shelf 2, that the blocking element 20 fits into the undercut 17 , This is achieved in that the depth of the undercut 17 in the extension direction X the distance of the locking element 20 from the region of increased cross-section 12th minus the distance of the first limiting element 21 from the front, the shelf 2 facing the end of the housing 9 corresponds.

In order to allow a flush termination of the housing at the front, the shelf 2 facing the end in the retracted retracted position of the retaining element 7, in particular to prevent ingress of dirt into the housing 9, it can be provided that the cross section of the locking element 20 at its the free end facing the second connecting element 5 corresponds to the cross section of the first guide section 10 in the region of the front end of the housing 9 facing the second connecting element 5. As a result, in the retracted retraction position, the housing 9 is sealed tight in the region of the first guide section 10. As can be seen from the illustration in FIG. 4, the holding section 13 can also be dimensioned such that in the extended holding position shown the region of the holding section 13 which bears against the front end of the housing 9 has the same cross section as the first guide section 10 , This prevents penetration of dirt through the clean completion even in the extended holding position of the support member 7.

In addition, the length of the retaining element 7, ie the distance of the free end of the locking element 20 from the rear end of the enlarged cross-section area 12, corresponds to the distance of the second limiting element 22 from the front end of the housing 9. This ensures that the blocking element 20 does not protrude relative to the housing 9 in the retracted retracted position, but terminates flush with the front end of the housing 9. Since the housing 9 is inserted into the shelf wall 3 in such a way that it is flush with the inside of the shelf wall with the front end, which is particularly easy to assemble, optically a particularly attractive shelf wall 3 is made possible, in which the not for the support of Shelves 2 used to complete the first connecting elements 4 flush with the shelf wall and form a visually uniform surface. In addition, there is no risk of injury by projecting from the shelf wall projections. If the blocking element 20, as described, alternatively cover the end face of the housing 9 facing the second connecting element 5, then the length of the holding element 7, ie the distance of the free end of the blocking element 20, must be provided for a flush closure of the first connecting element 4 with the shelf wall 3 from the rear end of the area with enlarged Cross section 12, the distance of the second limiting element 22 corresponds to the inside of the shelf wall 3 and the housing 9 is correspondingly shorter and recessed in the shelf wall 3 is formed. Further details and particular embodiments of the components of the holding device 1 are shown in the following individual representations in Figures 5 to 11.

FIG. 5 shows a perspective view of an exempt housing 9 of the first connecting element 4. The housing 9 is formed as a substantially cylindrical socket. In this view, the front, the second connecting element 5 facing the end of the housing 9, the first guide portion 10 can be seen, which adjoins directly to the front end of the housing 9 and is formed by a circular recess. At the rear end of the housing 9, the second limiting element 22 is arranged with the latching lug. The detent has an elastic web, which allows rebounding of the detent in the radial direction. On the outside, the housing 9 has serrated ribs 23 which point in the direction of the front end of the housing 9. These ribs 23 increase during the pressing of the housing 9 in the corresponding recess 6 in the shelf wall 3, the friction and thus the holding force on the housing 9. In addition, the ribs 23 allow not only the increased friction and a positive connection as a pull-out protection of the housing 9 in particular against installation direction. Instead of the ribs 23, other holding means, in particular a thread on the outside of the housing 9 may be provided. By means of a special key, which engages, for example, on the holding element 7 or the housing 9, the first connecting element 4 can be screwed into the recess 6 in the shelf wall and thus secured. A non-rotating connection of the retaining element 7 with the housing 9 can be achieved via the longitudinal groove 24. The special key may have a magnet, by means of which the holding element 7 is pulled into the extended holding position and thus can be gripped by the key. Furthermore, the housing has a longitudinal groove 24 in the first guide section 10, which extends from the front end of the housing 9 in the longitudinal direction of the housing 9 to the second delimiting element 22. As can be seen in particular from the longitudinal section through the housing 9 in FIG. 6, the longitudinal groove 24 extends both through the first guide section 10 and also the subsequent first one By this longitudinal groove 24, which is not absolutely necessary, on the one hand, the production of the second limiting element 22 is facilitated, but this longitudinal groove 24 can also be used as a guide and anti-rotation for the support member 7. For this purpose, a not shown, projecting in the radial direction guide member may be provided on the holding element 7, which engages in the longitudinal groove 24 and is guided there. In this way it can be ensured that the retaining element 7 is not rotated relative to the housing 9 in the case of a translatory displacement. This is particularly advantageous if the blocking element 20 of the holding element 7 is not rotationally symmetrical, but for example, only vertically protrudes upward and thus the exact positioning of the locking element 20 to the second connecting element 5 is necessary.

As can also be seen from FIG. 6, the second limiting element 22 directly forms a radially outer surface of the housing 9, in which, unlike the other cylindrical outer surface of the housing 9, no ribs 24 are provided. Regardless of whether or not such ribs are arranged on the radial outer side of the second delimiting element 22, this outer side of the second delimiting element 22 bears against the shelf wall 3 in the recess 6, so that a radial movement of the second delimiting element 22 designed as a latching nose is prevented , This ensures that in the installation position of the housing 9 in the shelf wall 3, the second limiting element 22 can not deform elastically, whereby a reproducible and durable stop for the support member 7 is ensured in the retracted retracted position. Alternatively, the corresponding outer side of the second delimiting element 22 may also have a minimal play with the recess 6 in the shelf wall 3 (as can the securing element 18 of the holder 15 with respect to the shelf 2) which is designed as an elastic detent nose, the play being opposite the engagement length of the delimiting element 22 (FIG. and the securing element 18) is dimensioned smaller in order to prevent unintentional release of the retaining element 7 (and the magnet 14).

FIG. 7 shows a side view of the released holding element 7. At the front, the second connecting element 5 end facing the locking element 20 is arranged. The blocking element 20 is formed by a circular annular web projecting in the radial direction in relation to a subsequent annular groove 25, the outer contour of which corresponds to the outer contour of the holding section 13 adjoining the annular groove 25. Adjoining the holding section 13 is the area of enlarged cross-section 12, which is arranged at the rear end of the holding element 7. The area with enlarged cross-section 12 is formed by an annular web whose outer contour is greater than the outer contour of the holding portion 13. The holding element 7 has a round cross-section, wherein other cross-sections, in particular angular cross-sections, in particular in the blocking element 20 and the holding portion 13 are conceivable to allow the above-described rotation of the retaining element 7 in the housing 9 in an alternative way. In this case, then at least the first guide portion 10 of the housing 9 is to be executed with a corresponding rectangular cross-section. By a rectangular cross-section, in which a lower contact surface of the first guide portion 10 extends horizontally, a particularly large contact surface for the holding member 7 and the holding portion 13 allows, whereby the surface pressure decreases and high weight forces of the shelf 2 in the shelf wall 3 are transferable , In addition, the relative rotation between the two connecting elements 4 and 5 is eliminated. In order to avoid tilting of the retaining element 7 relative to the second connecting element 5, the blocking element 20 may have rounded or chamfered edges. In addition, tilting of the locking element 20 relative to the housing 9 during the withdrawal as well as retraction of the holding element 7 is prevented.

Figure 8 shows a front view of the exempted second connecting element 5 from the perspective of the first connecting element 4. Like the housing 9 of the first connecting element 4, the holder 15 also has lateral ribs 26, which are directed downwards in this example. This is due to the fact that this holder 15 is designed to be pressed vertically upwards into a corresponding recess in a shelf 2, as shown for example in one of Figures 2 to 4. By the ribs 26 also increases the friction and thus the holding force of the holder 15 in the shelf 2. As well as the ribs 23 on the housing 9, the ribs 26 also allow a positive connection as a pull-out protection in particular against the installation direction.

At the flat end face of the holder 15 shown, a recess 16 is formed, which tapers towards the top. The upper region of the recess 16 is slightly larger than the cross section of the holding element 7 in the region of the annular groove 25. Lateral the upper portion of the recess 16 is limited by cheeks, but which can be significantly smaller or larger or with different contour, as shown. On the cheeks can also be dispensed with entirely, so that only a circular bottom in the upper region of the recess 16 is present. It is essential that the timing of the retraction of the retaining element is ensured in coordination with the other components. Also shown in Figure 8, the magnet 14 which is located directly behind the recess 16 in the holder 15.

As can be seen from the sectional view of the second connecting element 5 along the section line A-A of FIG. 8, an undercut 17 is arranged in the extension direction X of the retaining element 7 behind the recess 16, in particular behind the tapered upper region of the recess 16. This undercut 17 extends in the vertical direction upwards and is designed to receive the blocking element 20. The magnet 14 is inserted through an opening on one of the recess 16 opposite rear side of the holder 15 in the receptacle 19 of the holder 15 and arranged in the extension direction X directly behind the undercut. At the back of the holder 15 also ribs 26 are arranged.

By also designed as an elastic detent locking element 18 of the magnet 14 is held in the holder 15. As with the housing 9 of the first connecting element 4, the securing element 18 also forms an outer surface of the holder 15, which comes to rest on the shelf 2, so that release of the latching nose is prevented in the case of a second connecting element 5 installed in the shelf 2.

Figure 10 shows a front view of a first alternative embodiment of the second connecting element 5. In contrast to the embodiment shown in Figure 8, the holder 15 has an elongated, in the vertical direction extending shape. As a result, a longer clamping range is made possible, which acts as additional pull-out protection due to the friction. The recess 16 also extends downwardly from an upper tapered portion in the upper part of the holder 15 in a vertical direction substantially to the lower end of the holder 15. The magnet 14 is in the upper part of the holder 15, again behind the tapered portion of the recess 16 arranged, but elongated, whereby a secure attraction of the support member 7 in Clamping range and even before it is reached. Due to the elongated shape of the magnet 14 can first pull the retaining element 7 during assembly completely in the extended position, resulting in a pleasant for the user click sound as an acoustic trigger signal. Although not shown, the alternative embodiment of the second connecting element 5 shown, as well as the second connecting element 5 shown in FIGS. 8 and 9, may have ribs 26 or the like on the outside, in order to increase the friction and thus the holding force in the shelf 2 increase. This first alternative embodiment of the second connecting element 5, like the second connecting element 5 described above, can be arranged vertically in the end face of the shelf 2, wherein the shelf 2 must then have a corresponding thickness.

In order to integrate the shown first alternative embodiment of the second connecting element 5 in a shelf with visually appealing low strength, the first alternative embodiment of the second connecting element 5 can also be mounted horizontally or aligned at an acute angle to the horizontal on the shelf 2. In this case, unlike the purely vertical movement of the previously described second connecting element 5, the assembly and release movement of the shelf is a combination of horizontal and vertical or purely horizontal movement. Since, in the horizontal arrangement of the second connecting element 5, the loosening direction between the connecting elements 4, 5 is also arranged horizontally, e.g. cantilevered shelves or drawers can be installed without tilting, since vertical forces can be absorbed upwards. This also represents a particular advantage in terms of parental control. In addition, the second connecting element 5 can be invisibly integrated from the outside in the front side of the shelf 2, which in addition to the optical advantage also prevents unwanted removal of the shelf 2, as not from the outside It can be seen how the shelf 2 can be removed.

Furthermore, with such a second connecting element 5, it is also possible to achieve a connection of elements along their longitudinal axis on the end faces, such as the connection of two shelf side walls one above the other for stacking shelves or extending the shelf walls. Such a connection of two shelf side walls one above the other is stable against lateral forces and tilting loads on the shelf wall and can only be solved in a relative mutual movement in the longitudinal direction of the shelf walls. Due to the long clamping range can this alternative embodiment of the connecting element 5, both vertically and horizontally installed state, for example, used as a connection of a statically stabilizing rear wall, which is protected due to the invisible positioning of the connecting element 5 in, for example, the front edge of a board against an unintentional solution. Likewise, overhanging doors can be mounted in a positionally secure manner via this alternative embodiment of the connecting element 5.

This first alternative embodiment of the second connecting element 5 can then be fastened by means of the ribs already described or by screws in a corresponding recess in the end face of the shelf 2. For this purpose, the first alternative embodiment of the second connecting element 5 may preferably be made slightly longer so that two screw holes can still be placed. This is expedient in particular in the first alternative embodiment of the second connecting element 5, since not much wall thickness up and down remains at installation on the front side of the shelf 2, so that the pressure through the ribs deform the shelf 2 in this area and thus could damage.

A particular optical advantage results in a reversed arrangement, when the first alternative embodiment of the second connecting element 5 in the shelf wall 3 and the first connecting element 4 is arranged in the shelf 2. In the above-described horizontal arrangement of the first alternative embodiment of the second connecting element 5, the holding device would then not be visible above the shelf 2 when installed. In addition, this arrangement is cost-effective, since the complex and thus more costly first connecting elements 4 are present only in the shelves 2 and does not need to be kept in a significantly higher number in the shelf walls 3 in the different available heights.

FIG. 11 shows a sectional illustration of the first alternative embodiment of the second connecting element 5 of FIG. 10 along the section line BB. As can be seen from the illustration, the depth of the recess 16, starting from the undercut 17, is reduced downward, in particular the depth of the recess 16 is reduced gradually and without steps or edges to the value zero. This ensures that when dismantling the shelf 2, in which the shelf 2 with the second connecting element 5 with respect to the shelf wall 3 with the first connecting element 4th is raised, the holding member 7 is pressed by the recess 16 in the retracted retracted position, whereby the effect of the spring element 8 is additionally supported. However, it is also possible, the described holding element 1 with this alternative connecting element 4, but without the spring element 8 and the corresponding area with enlarged cross-section 12 and the region of reduced cross-section to perform, the provision of the retaining element 1 thereby exclusively on the decreasing depth of the recess 16 takes place. This constitutes a separate invention per se. Preferably, an area with a constant depth is provided in the recess between the undercut 17 and the section with the infinitely reducing depth, this area corresponding at least to the dimensions of the blocking element 20 of the retaining element 7.

FIG. 12 shows a front view of a second alternative embodiment of the second connecting element 5. Like the first alternative embodiment of the second connecting element shown in FIG. 10, the holder 15 has an elongate, vertically extending shape. The recess 16 also extends downwardly from an upper tapered portion in the upper part of the bracket 15 in a vertical downward direction substantially to the lower end of the bracket 15. Although not shown, the second alternative embodiment of the second connecting member 5 shown may be like FIG also have the first embodiment of the second connecting element 5 shown in Figures 10 and 11 on the outside ribs 26 or the like in order to increase the friction and thus the holding force in the shelf 2. In contrast to the first embodiment of the connecting element, however, the upper region of the second alternative embodiment of the connecting element 5 in the form of a slot 27 is formed. At the upper end of the slot 27 27 on each side of the slot 27 opposite locking lugs 28a, 28b are provided, each projecting into the longitudinal hole 27. However, the latching lugs 28a, 28b are not absolutely necessary for a proper function of the second connecting element 5, it is also possible merely to achieve a clamping effect on the retaining element 7 solely due to friction solely by the dimension of the oblong hole. The locking lugs 28a, 28b represent only an additional lock.

The locking lugs 28a, 28b stand just so far into the slot 27, that the width of the slot 27 in the region of the locking lugs 28a, 28b is slightly smaller than that Width and the diameter of the retaining element 7 shown in Figure 7 in the region of the annular groove 25. When inserting the retaining element 7 engages behind the annular web formed as blocking element 20 on the holding element 7, the slot 27 and the bottom of the annular groove 25 slides along the side surfaces of the slot 27. As soon as the bottom of the annular groove 25 pending on the detents 28a, 28b on the side surfaces of the slot 27, these locking lugs 28a, 28b are pressed elastically outward in a further insertion of the retaining element 7 and then spring back again. The locking lugs 28a, 28b can be arranged on the side surfaces of the slot 27 so that they then spring back when the holding element 7 comes to the upper, preferably closed end of the slot 27 to the plant. In the embodiment shown, the upper end of the oblong hole 27, together with the latching lugs 28a, 28b, forms a circular section-shaped cross-section, which essentially corresponds to the cross-section of the retaining element 7 in the region of the annular groove 25. As a result, the retaining element 7 is held reliably latching in the upper position in the slot 27, whereby in addition to the attraction by the magnet 14, not shown here, an additional locking of the retaining element 7 takes place on the holder 15. The detents 28a, 28b may be formed abruptly protruding or over a greater distance with a soft transition.

As can also be seen from FIG. 12, the holder 15 has slots 29a, 29b arranged laterally next to the slot 27 in each case. The slots 29a, 29b extend substantially over the length of the slot 27, but in particular in the region of the locking lugs 28a, 28b. The slots 29a, 29b are arranged parallel to and at a small distance from the slot 27 and increase the elasticity of the side walls of the slot 27. However, the slots 29a, 29b may also be curved or angular. If the retaining element 7 is inserted into the slot 27, the side walls of the slot 27 in the direction of the slots 29a, 29b elastically deform, which is why the elasticity of the side walls of the slot 27 and thus the holding force of the locking lugs 28a on the geometry of the slots 29a, 29b , 28b can be adjusted relative to the retaining element 7. However, the slots 29a, 29b are not absolutely necessary for a proper function of the second connecting element 5, it is also, in particular in combination with missing locking lugs 28a, 28b, possible only due to friction solely by the dimension of the slot a clamping action on the retaining element. 7 to reach. An additional guide and frictional retention of the retaining element 7 is achieved in that the side walls of the slot 27 converge straight upwards or curved upwards to the latching lugs 28a, 28b, thus reducing the distance between the side walls. In this way, on the one hand, the friction and thus the attachment of the holding member 7 is improved on the holder 15, but also the handling of the assembly of the holding member 7 is optimized with the holder 15, as with a correct insertion of the holding member 7 in the slot 27 of the resistor slowly rises until the locking lugs 28a, 28b are overcome. If the side walls of the oblong hole 27 are designed to converge, the slots 29a, 29b are preferably also arranged laterally next to the side surfaces of the oblong hole 27. It may also be advantageous not to perform the side walls of the slot 27 in mirror image, but to arrange a side surface stronger in relation to the longitudinal extent of the holder 15, as the opposite side surface. The resulting resulting leadership through the side surfaces has an oblique to the longitudinal extension of the bracket 15 center line, whereby an additional bracing and thus fixing the connecting elements 4, 5 can be achieved to each other. The elongated hole can also have an oblique, rounded or abrupt course as well as a profiled surface per se, that is to say even in the case of parallel side walls. As a result, additional frictional force or generally insertion and removal properties can be set.

Figure 13 shows a sectional view of the second alternative embodiment of the second connecting element 5 along the section line CC of Figure 12. As can be seen there, the holder 15 also has a receptacle 19 for the magnet 14, but wherein the receptacle 19 at one of the recess 16 opposite side of the holder 15 is formed as a blind hole, so not protruding to the recess 16. As a result, damage to the magnet 14 is prevented and formed a visually appealing through recess 16, wherein the magnetic forces are not appreciably affected by the thin wall between the magnet 14 in the receptacle 19 and the recess 16 for the retaining element 7. The continuous thin wall serves the holding element 7 as a continuous guide both in the connection and during the release process. The holding element 7 is guided cleanly and steplessly, in particular in the solution of the connection, up to the complete insertion position in the housing 9. For easier mounting of the magnet 14, the receptacle 19 has a circumferential chamfer. As can also be seen from FIG. 13, the vertical cut 17 tapers in the direction of the upper end of the oblong hole 27, whereby in addition a clamping effect can be achieved with respect to the blocking element 20 of the holding element 7, which is guided in the vertical cut and designed as an annular web. For this purpose, the width of the Hmterschneidung 17 in the direction X at the narrowest point is slightly smaller than the width of the blocking element 20 to choose. The width of the Hmterschneidung 17 at the narrowest point can also correspond exactly to the dimension of the width of the locking element 20 or minimally dimensioned. The smallest width of the Hmterschneidung 17 in the direction X can be arranged substantially in the region of the upper end of the elongated hole 27, in order to achieve a clamping action in the retracted position of the holding element 7. But it can also be provided analogously to the locking lugs 28a, 28b to arrange the region with the smallest width of Hmterschneidung just below the upper position of the holding member 7 in the slot 27 and the width of Hmterschneidung 17 in the upper position of the holding member 7 in the Long hole 27, so at the upper, closed end of the slot 27, slightly wider perform to reach by the Hmterschneidung 17 and the locking element 20 a catch. This locking could also be provided at the beginning of the slot 27 or between the beginning of the slot 27 and the position of the locking lugs 28a, 28b, to realize a double locking one behind the other. By locking lugs 28a, 28b together with the clamping by the minimal narrow width of Hmterschneidung 17 in the X direction compared to the width of the locking element 20, a clamping / latching on two mutually perpendicular clamping / locking surfaces and thus a three-dimensional latching can be formed.

The intersection 17 is dimensioned such that it also measures exactly its dimension or minimally in the axis of the diameter of the blocking element 20. As a result, a further formschlussgebende fixation is realized. The Hmterschneidung 17 and thus the clamping area can be formed so that the wall at the bottom of the recess 16 and / or the opposite bottom of the slot 27 are not formed as shown vertically, but slightly oblique, rectilinear or curved / elliptical up to converge towards each other , In addition, an insertion bevel is provided at the beginning of the clamping area to ensure reliable insertion of the locking element 20 of the retaining element 7 in the undercut 17 to ensure. For a reliable fixation of the second alternative embodiment of the second connecting element 5 in the shelf wall or the shelf, this has also on the outside of the holder 15 arranged, circumferential ribs 26.

FIG. 14 shows a perspective view of the second alternative embodiment of the second connecting element 5. As can be seen there, the slot 27 with the locking lugs 28a, 28b and the slots 29a, 29b in a recess 16 partially upwardly or externally bounding cover 30 are integrated. Below the cover 30, so as shown in Figure 13 in the direction X of the cover 30, the undercut 17 is arranged, which is formed by a free space which is bounded by the cover 30 against the direction X, ie to the outside and to optionally clamped receiving the locking element 20 of the retaining element 7 is formed. As also described with regard to the first alternative embodiment of the second connecting element, the depth of the recess 16 in FIG. 13 is reduced starting from the undercut 17; in particular, the depth of the recess 16 is gradually reduced to zero with no steps or edges , for example in elliptical form. The other features, unless they are described separately, correspond to the features of the first alternative embodiment, which is why reference is made thereto.

FIG. 15 shows a front view of a third alternative embodiment of the second connecting element 5. There, in contrast to the second alternative embodiment of the connecting element, the receptacle 19 for the magnet 14, not shown, extends as far as the recess 16, so that a continuous recess is formed by the holder 15 through the receptacle 19 and the recess 16. As a result, the magnetic force of the magnet 14 can act unimpeded on the holding element 7 and in particular the blocking element 20 in the recess 16, whereby particularly high holding forces are achieved. By this embodiment magnets with lower adhesion and / or dimension can be used, which saves costs and can be managed more sustainably.

The receptacle 19 for the magnet 14 and thus also the magnet 14 does not extend in this embodiment over the maximum width of the recess 16, so that on both sides of the receptacle 19 a step is formed by a respective web 32 a, 32 b, which as Attachment for the blocking element 20 of the retaining element 7 serve. The webs 32a, 32b extend substantially over the length of the receptacle 19 and in particular in the region of the cover 30 with the slot 27 and thus ensure a secure guidance of the locking element 20 on the two webs 32a and 32b. The magnet 14 is dimensioned smaller by the dimension of these two webs 32a, 32b than the blocking element 20 and thus the width of the clamping region or the undercut 17 in the holder 15 shown in FIG.

At the lower end of the webs 32a, 32b shown in Figure 15, the recess 16 has a recess which is elliptically shaped at its lower end, so that the guide of the locking member 20 gradually from the webs 32a, 32b via the recess 31 to the holder 15 or the bottom of the recess 16 can be passed in the lower area itself. Then, the blocking element 20 is guided at its foremost, in the illustration shown lowest point to the lower end of the recess 16 at which the inclined ramp in the recess 16 in the depth to zero tapers. This prevents the locking element 20 abuts the holder 15 during the release process and thereby jammed. Through the depression, such a contact is prevented and ensures a secure stepless guidance of the cross-sectionally round locking element 20 on the lateral webs 32a, 32b to the lower part of the recess 16.

The webs 32a, 32b may be made very small dimensions under certain circumstances, so that just a minimal part of the locking element 20 rests against these or can be performed. A consequence of this may be that is completely dispensed with the guide at the outer / lower end of the locking element 20 (ie, for example, the webs 32a, 32b) and the positive connection in the movement axis of the holding element 7 exclusively on the maizexakte clamping of the support member 7 and the (wall -) strength of the slot 27 and the cover 30 is realized. The retaining element 7 can extend by its dimension and the size of the housing 9 only to a certain extent. Exactly to this degree (or minimally above / below), the (wall) thickness of the slot 27 and the cover 30 is dimensioned, whereby a relative pressure of the second connecting element 5 in the extension direction of the holding member 7 to the housing 9 can be realized. The (wall) thickness of the slot 27 and the cover 30 accordingly corresponds exactly (or minimally more / less) the width of the annular groove 25 of the retaining element 7 which is mounted below the blocking element 20. FIG. 16 shows a sectional illustration of the third alternative embodiment of the second connecting element along the section line DD of FIG. As can be seen from the illustration, the web 32b extends as well as the web 32a, not shown, over the entire length of the receptacle 19 between the recess 16 and the receptacle 19. To secure fixing of the magnet 14, not shown, in the recess 19 against the direction To reach X, a projection 33 is provided between the receptacle 19 and the recess 16 at the lower end, which serves as a stop point for the magnet 14. This projection 33 is arranged in the region of the recess 16, in which the depth of the recess 16 is reduced continuously. For this reason, the projection 33 has a wedge-shaped cross section. In addition, the described recess 31 is arranged in the projection in order to avoid a striking and tilting of the blocking element 20 on this projection 33 during the release process. The contact side facing the receptacle 19 for the magnet 14 is aligned with the rectilinear portion of the steps 32a, 32b in the region of the undercut 17. This ensures that the magnet 14 is flush with the webs 32a, 32 in the installed position and in no way too wide projects to the right, whereby the undercut 17 would be too small for receiving the locking element 20. Therefore, the magnet 14 is also preferably longer than the aperture between the recess 16 and the receptacle 19 is formed. The length of the magnet 14 in the vertical direction of Figure 16 can be made longer than the flat, rectilinear portion of the recess 16. This results in the projection 33 as a stop point for the magnet 14, since the breakthrough between the receptacle 19 for the magnet 14 and the recess 16 does not extend over the entire length of the magnet 14. The described stop defines the installation depth of the magnet 14 in the receptacle 19 of the holder 15 and thus the thickness or in Figure 16, the width of the undercut 17. The width of the magnet 14 in the horizontal direction of Figure 15 can be chosen to be less than that Diameter / the width of the locking element 20 of the holding element 7, whereby the webs 32a, 32b arise at which the blocking element 20 can be performed. In this case, the magnet 14 and the holding element 7 experience direct contact when the undercut 17 in its thickness or in its horizontal width in FIG. 16 corresponds exactly to the thickness of the blocking element 20. The magnet 14 can also be chosen larger in its width than the difference of the maximum diameter / width of the blocking element 20 and the width of the two webs 32a, 32b. In this case, the magnet 14 lies in the direction X below the webs 32a, 32b, resulting in a certain distance between the magnet 14 and the retaining element 7 results, which is why this embodiment basically corresponds to Figures 12 to 14 only with a partially arranged breakthrough. Manufacturing technology, it is difficult to implement the projection 33 for the magnet 14 at its thinnest point (in the direction of the undercut 17, ie at its free end) so small dimension that he in the vertical direction of Figure 16 no significant stage for the retracted holding element 7, since, in particular in the case of a radial, circular form of the blocking element 20, this always has its center in the center in the direction of the release in the vertical direction, in FIG. 16 the lowest point in the vertical direction. Therefore, even with a guide by means of the webs 32a, 32b, this step would be an obstacle to the retaining element 7 during the release process. To avoid this disadvantage, the recess 31 is provided in the projection 33, which ensures that the projection 33 is tapered and thus does not form a stop for the blocking element 20. Thus, the support member 7 ideally ideally stepless in his leadership of the webs 32 a, 32 b transferred to just this recess 31 and finally to the lower part of the recess 16 of the bracket 15 itself and out.

FIG. 17 shows a perspective view of the third alternative embodiment of the second connecting element 5 obliquely from above. As can be seen there, this embodiment of the second alternative embodiment differs only in the formation of the opening between the receptacle 19 and the recess 16 and the recess 31 with the lateral webs 32a, 32b, so that with respect to the further features of the aforementioned Reference is made to embodiments. In Figure 18 is a further perspective view of the third alternative embodiment of the second connecting element 5 is shown obliquely from below, from which the projection 33 can be clearly seen as a stop for the magnet 14, not shown in the receptacle 19. The projection 33 extends between the webs 32a, 32b and abuts against the opposite side walls of the receptacle 19 for the magnet 14.

FIG. 19 shows a perspective illustration of a fourth alternative embodiment of the second connecting element. This embodiment is similar to the embodiment shown in FIGS. 8 and 9, but with the receptacle 19 for the magnet not disposed opposite the recess 16 on the holder 15. but on an adjacent side, here the top of the holder 15. The magnet 14 can therefore be inserted from above into the holder. Thus, the extension direction is in the weak magnetization direction and the magnet 14 is consequently not pulled out so easily during transport. In addition, the securing element 18 comprises two opposite snap hooks for fixing the magnet 14, not shown. The ribs 26 on the outer side of the holder 15 furthermore preferably have at least one step 34 at the widest point of the holder 15, which preferably has a sharp-edged design and thus a twisting the substantially circular holder 15 prevents in the shelf. In order to block a twist in both directions, it is expedient to provide a further opposite step to the ribs 26. These steps 34 may also be formed in the previously described embodiments, in particular the embodiment shown in FIGS. 8 and 9. The thickness of the ribs 26 tapers in the direction of the recess 16 to zero, resulting in optical advantages in the installed state, since there is no visible gap between the carrier material (eg wood panel) and connecting element.

These described alternative embodiments of the second connecting element 5 can, as already described for the first embodiment of the connecting element, be fastened vertically to the shelf 2 in the front side of the shelf 2 or horizontally or at an acute angle to the horizontal. For the further advantageous features, reference is made to the above statements, which are freely combinable.

In addition, in all the embodiments of the second connecting element 5 shown, a mechanical securing device for locking the retaining element 7 in the clamping region or the undercut 17 may be formed. This may be, for example, attached to the holder 15, linearly displaceable and spring-biased slide, which is first automatically pushed away when inserting the retaining element 7 in the undercut 17 and then the retaining element 7 engages behind a positive fit. By appropriate bevels on the slide, the automatic opening of the slide during insertion of the holding element and by corresponding further bevels on the opposite side of the slide, the force-induced release of the holding element can be achieved. About the angle of the slopes on the slide can be adjusted for the locking as well as for loosening the necessary force. This will prevents inadvertent release of the connection, whereby the child safety or general injury protection is improved. However, instead of the spring preload, the slider may also be movable only mechanically / manually. As a slider in this sense, in addition to a longitudinally movable shutter and a screw cap to understand as a lever.

FIG. 20 shows a perspective front view of an alternative embodiment of the housing 9 of the first connecting element 4. In contrast to the embodiment in Figures 5 and 6, however, the second limiting element 22 is not formed as inwardly projecting hook-shaped locking lug, but as projecting rearwardly of the sleeve-shaped housing projections. However, these second limiting elements 22 in the raw form of the housing 9 shown are not projecting radially inwards beyond the second guide section 11. This has the advantage that in the manufacture of the housing 9, for example by means of injection molding no longitudinal groove 24 for demolding of the hook-shaped limiting element 22 as in the embodiment in Figures 5 and 6 is necessary. The visible in Figure 20 and visible after installation front of the housing 9 thus forms together with the locking element 20 of the retaining element 7, not shown, a closed outside, which has both aesthetic and cleaning advantages.

As can be seen from the perspective rear view of the alternative embodiment of the housing 9 of the first connecting element 4 in FIG. 21, a plurality of such second limiting elements 22 can be arranged on the rear side of the housing 9. However, it is also possible to form the projections, for example, completely encircling. In addition, a combination of materials, for example, take place in that the projections are formed of metal, which are then connected during injection molding with the rest, for example made of plastic housing 9. For example, since metal flakes are much easier to plastically reshape, a second limiting element 22 can be formed in a particularly simple and stable manner. After the mounting of the holding element 7 with the spring element 8, these second limiting elements 22 can be deformed radially inwardly simply by means of cold or hot deformation, so that they project inward and form a boundary for the holding element 7. As a result, a particularly cost-effective production and assembly is possible. Such protrusions or a snap hook can also in the illustrated embodiments of the second Connecting element 5 may be provided to allow a reliable fixation of the magnet 14. In addition, the housing 9 at the opening of its first guide portion 10 may have rounded or chamfered edges in order to avoid tilting of the holding element 7 during extension and retraction.

The embodiments described and shown in the figures can also be used in general for the connection of furniture pieces, for example for the positioning and fixing of stacked boxes. Due to the magnetic force, the holding device can be spatially freely arranged on the furniture. This is especially true in combination with the above-described additional magnetic elements for mutual positioning of the furniture parts to be joined.

In all the embodiments shown, instead of the magnet 14, the holding element 7 of the first connecting element 4 may be wholly or partly magnetic, in which case the second connecting element 5 consists of a magnetically attractable material such as steel, iron, etc. It is also possible for both the second connecting element 5 and the retaining element 7 of the first connecting element 4 to be wholly or partially magnetically executed. In this case, the poles of the magnets are to be aligned so that the holding element 7 is used to the second connecting element 5, when the second connecting element 5 comes in the vicinity. In order to achieve a visually appealing and uniform surface and to protect the second connecting element 5 designed as a magnet from damage, the second connecting element 5 can be partially or completely covered by a cover, for example made of plastic.

The features disclosed in the individual embodiments can be readily combined according to the invention in order to achieve the desired effects and are not bound to the respective embodiment. LIST OF REFERENCE NUMBERS
