Description

Assembled element and corner connection to it {COMPOSED ELEMENT AND CORNER CONNECTION APPLIED HEREWITH}

The present invention relates to a assembled element and a corner connection applied to the assembled element.

More specifically, the present invention relates to an assembled element comprising at least two panel-shaped elements which are joined together, which can be joined to each other at an angle, whether or not an intermediate member is used. Herein, the present invention provides at least two or more independent applications, regardless of whether the assembled element consists essentially of panel-shaped elements only or whether these panel-shaped elements form only a portion of the assembled element. To any type of assembled element comprising panel shaped elements.

The present invention may be used in any application, but its primary object is to apply to the field of furniture with stand-alone furniture as well as built-in furniture such as wardrobes, dividers and the like.

More specifically, the present invention aims at connections between panel-shaped elements, which panel-shaped elements can be realized smoothly and used in furniture that is sold in disassembled state and must be assembled by the purchaser himself. Is suitable to be. The present invention here relates primarily to the so-called flat-pack furniture.

More specifically, the invention relates to an assembled element comprising two or more panel-shaped elements, each panel-shaped element being preferably in the form of a profile in which the joining portions each extend in the longitudinal direction of each joining region. Preferably a joining region, each present in the form of a tongue and groove, wherein these profiles allow the panel-shaped elements to be joined to each other in a locking manner and at an angle. Such assembled elements are known in particular from the document DE 20 2009 008 825 U1. The use of such profiles, which are provided within the panel-shaped elements themselves and whose entirety or a major part thereof is made integral with the panel-shaped elements, angle the panel-shaped elements, for example metal connecting elements. The advantage is that separate elements for the connection are unnecessary or at least the use of such separate elements can be limited to a minimum. Its other advantage consists in that such profiles can be milled in a simple manner with panel-shaped elements and that continuous locking engagement can be realized along the entire corner connection.

It is evident that such bonding is exerted not only during bonding but also after bonding. Given that these profiles must be realized in practice in most relatively thin panels, and often also to be realized as particle boards that are also known to be fragile, known profiles provide only a limited number of choices for optimization. do.

The invention therefore aims, in particular, to improve assembled elements of the type as described in DE 20 2009 008 825 U1.

To achieve this object, the invention according to the first aspect is an assembled element comprising at least two panel-shaped elements, the panel-shaped elements being provided directly or by an intermediate member, by means of a locking tongue and a recess connection. Can be indirectly angled to one another by means of a connection, and the connection can cooperate with grooves or tongues provided on the other panel-shaped elements or provided on the intermediate member, at least in one of the panel-shaped elements. A tongue or groove therein; The tongue consists of a split tongue having at least a first portion and a second portion as well as a slit positioned between the first portion and the second portion; And a locking portion is provided at least on the outer side of the first portion, wherein the slit comprises at least one side when viewed in the cross section of the tongue, and the orientation of the side as viewed in the cross section is deflected from the main direction belonging to the tongue. To an assembled element. By using a slit, the advantage is obtained that at least one side of the slit has a deflecting orientation, and a new parameter is created that provides new choices for optimizing such a bond.

In the most preferred embodiment, the second part of the tongue is free of locking parts. This allows the tongue to always fit smoothly into the recesses in the second part, and the optimization of engagement and locking can be realized substantially alone through the second part. According to a variant, the second part of the tongue actually comprises a locking part, which locking part is less pronounced than the locking part provided on the first part of the tongue.

According to another preferred feature, the tongue and the groove can be pivoted with each other, and the corner portion of the starting point from which the tongue and the groove can be pivoted with each other forms an inner corner portion, and a first portion of both of the portions of the tongue is this inner corner. It is located closest to the part. This allows for smooth engagement by pivoting movements.

More specifically, the tongue is preferably located eccentrically with respect to the panel-shaped element to which this tongue is provided, or with respect to the panel-shaped element to which it is joined, preferably in the direction of the inner corner portion described above. Due to the eccentric arrangement, the tongue can be kept farther away from the outer corner portion, thereby keeping more material usable in the outer corner portion, resulting in a more rigid structure at the outer corner portion. Is maintained, thereby reducing the risk of breakage of the material parts. The eccentric arrangement towards the inner corner also allows the tongue to pivot more smoothly into the groove.

According to another preferred feature, the tongue is configured such that the first portion of the tongue protrudes farther than the second portion of the tongue. The advantage is that in this case the first part provides sufficient space for the locking part, while the second part allows for smooth turning motion and / or to allow more material to remain in the position of the grooves. It is kept smaller.

According to the invention, it is preferred that the sides of the slit located on at least the first part have an orientation which is biased from the above-mentioned main direction. This allows the characteristics of the first part of the tongue to be influenced not only in elasticity but also in strength, in which way new parameters are created for the design engineer to realize the desired combination of the resulting function. Is obtained. This is very important for the first part of the tongue, since the first part of the tongue comprises the most important locking part, and its elasticity as well as its stability determine the good function and strength of the bond. More preferably, the inward facing side of the aforementioned slit substantially approaches the plane defined by the surface of the panel-shaped element located on the same side as the first portion of the tongue. By this, the end of the first part is kept relatively strong and strong, which is beneficial for the strength of the locking part provided on the first part, while creating a higher elasticity inwardly, which is the It is obtained that the first part and the associated locking part are important for producing a suitable elasticity that can be displaced. In this way, both properties are defined on two different locations by their general technical shape, which also gives the advantage that the design engineer can influence these properties independently.

According to the invention it is clear that the orientation deflected from the above-mentioned main direction can be provided even on the side of the slit located on the second part, whether or not in combination with the preceding second features. As such, this also provides the advantage that a new parameter is created which can be used by the design engineer to optimize the technical features of the tongue and recess coupling of the desired effect function. In this case it is also preferred that each side facing inward of the slit substantially approaches a plane defined by the surface of the panel-shaped element located on the same side as the first portion of the tongue. By such an orientation, it becomes possible to realize the base of a 2nd part relatively firmly and stably, but keeping the front end part thin especially.

As mentioned above, the sides exhibiting an orientation deflected from the main direction preferably extend in a substantially inclined state, more preferably in a straight line over most of the full length thereof. More specifically, the slits as a whole preferably have parallel sides, more preferably formed by incisions and extending at an angle. This allows the realization of such side and even whole slits in a simple way by a saw cutter. Such an inclined slit having a uniform width over its length can thus combine at least three advantages: easy realization of the slit, optimization of the first part and optimization of the second part.

Preferably, the slit extends deeper than the base of the tongue and the sides, sides deflected from the main direction, will each show a deflecting orientation with respect to at least a portion of the slit extending deeper than the base. In this way, not only are the protruding parts of the tongue involved in the behavior of the tongue during joining, but the edges located further inside of the panel-shaped elements also have an effect on this in this situation, and additional freedom is obtained for the design engineer. Can lose. Moreover, it is preferable here that the sides, sides which are deflected from the main direction, each exhibit a deflecting orientation with respect to at least a portion of the slit which extends at least deeper than the base. In combination with this, the distance that the slit extends inside the panel-shaped element or auxiliary member, respectively, from the closing surface of the base is longer than the maximum distance that the tongue extends to the outside of the closing surface and / or to the outside of the base of the tongue. It is also preferred.

It is noted that the tongue is preferably located on the end wall edge of the panel-shaped element, and the plane associated with the tongue is to be understood as the plane in which the panel-shaped element is located.

In this embodiment, the joining region 11 is in this case formed by the edge of the small end of each panel-shaped element in which the tongue is located. In this case, the joining region 12 consists of one region of each other panel-shaped element in contact with the small end edge of the element of such panel-shaped edge.

The tongue 15 consists of a split tongue and therefore has at least two parts 21, 22 and a slit 23 located between these parts. The slit is delimited by the sides 24, 25 and the bottom face 26, which are located on the portions 21, 22, respectively. Said two parts 21, 22 of the illustrated embodiment, hereinafter referred to as first part 21 and second part 21, respectively, have different lengths L1, L2.

According to variants not shown, it is noted that the tongue may consist of two or more parts, for example if a part of the extra material must be present in parallel with the slit. In this case, the slit previously targeted is divided into two slits, namely.

The outer portions 27, 28 of the portions 21, 22 shown in the figures cooperate with the side walls 29, 30 of the recess 16. Moreover, the recess 16 has a bottom wall 31. As shown, this bottom wall is preferably adapted to different lengths L1 and L2 with respect to the shape, so that the deeper portion 32 and the less excess material 34 are kept in the position of the less deep portion 33. The deep part 33 is shown. Maintaining this material portion 34 is less important for T-shaped connections, but in the case of single-fold corner connections, in this way, in order to maintain a more stable overall, it also forms a boundary of the groove. In order to avoid the risk of lateral fracture of the material, it is actually important. Therefore, the parts 32, 33 of the bottom wall 31 remain in the engaged state spaced apart no more than 2 mm from the farthest distal ends of the parts 21, 22, again. In other words, it is preferable to follow the overall shape of the tongue 15.

A recess 35 is formed in the side wall 29, so that the portion located in front of the recess functions as the locking portion 18. The locking parts 17, 18 define the locking surfaces 36, 37 which engage.

The locking part 17 is located on the first part 21 of the tongue.

As shown in the figures, it is noted that the first portion 21 has the locking portion 17, while the second portion 22, as shown, preferably has no locking portion. . This configuration allows the tongue to be easily pivoted into the groove by the pivoting movement W without creating a large force in the engaging portions, as shown in FIG. 5. However, the present invention does not exclude that the locking part is also present on the second part 22, in which case it is preferable that this locking part is less prominent than the locking part 17. This less prominent or therefore smaller locking portion is shown in dashed lines as an embodiment in FIG. 4 and is indicated at 38, where the locking portion is realized as a local protrusion, which is also a dashed line. It can cooperate with the recessed part 39 shown.

According to the invention, the slit 23 when viewed in the cross section of the tongue 15 comprises at least one side, the orientation of this side when viewed in cross section being deflected from the main direction D1 with respect to the tongue, and It is preferable to extend at an angle with respect to the main direction D1. In the illustrated embodiment, both sides 24 and 25 are realized in an inclined manner in the embodiment parallel to each other, so that the slits 23 in the tongue as a whole are shown to extend inclined with respect to the main direction.

Here, as for the side part 24 which borders on the 1st part 21 of the tongue 15 shown as a whole, this side part 24 is the 1st of a dividing tongue, from the distal end to the proximal end of the slit 23. The first part 21 and / or the first part 21 in a direction inclined with respect to the main direction D1, in other words, to approach the surface 40 located on the same side as the part 21. The portion of this provided panel-shaped element extends in an inclined direction such that the slit becomes overall thinner toward the proximal end as compared to embodiments in which the slit is not inclined. It is clear by this that the first part 21 is elastically displaceable in a relatively smooth manner.

The side portion 25 of the slit 23 bounding the second portion 22 as shown in total extends inclined with respect to the main direction D1, so that this side portion is formed from the distal end to the proximal end of the slit. Far from the surface 41 located on the same side as the two parts 22, in other words, this side 25 extends in an inclined manner in the same direction as the side 24. In the embodiment shown, this contributes to the stronger and more stable base of the first part 22.

Here, the whole is designed such that the first part 21 and in particular its locking part 17 are elastically displaceable in a smoother way than the second part 22, the second part being relatively rigid. The smooth elastic displacement of the locking portion 17 is because the first portion 21 is thus longer than the second portion 22, but rather than the first portion 21 of the panel-shaped element 2d, That is, it is obtained because it is adjacent to and supported by the thin material part separated by the slit 23 of the panel-shaped element located between the side part 24 and the surface 40 of the slit. The sides 24 extend obliquely in the direction shown, so that a relatively thin portion of material remains adjacent to the innermost end of the slit, and this relatively thin portion of material is located relatively far from the locking portion. This promotes smooth elastic flexural deformation at the height of this material portion.

By "slit" is to be understood both the portion which divides the tongue and the deeper extension in the panel shape.

The overall direction of the side part 24 of this embodiment and / or the overall or average direction D2 of the slit 23 is deflected from the main direction D1 over the angle indicated by A1. The magnitude of this angle is preferably located in the range of 2 to 20 degrees. When the bond has a normal strength, preferably an angle A1 in the range of 2 to 8 degrees is used, with about 4 degrees being preferred. When a low rigid coupling is required, that is, when a coupling that can be smoothly snapped together is desired, an angle A1 of 8 to 20 degrees is preferably used.

In the embodiment shown, the tongue 15 is located on the small side of each panel shaped element. Here, the main direction D1 belonging to the tongue should be understood as the direction of the plane in which the panel-shaped element 2d is located.

As shown, the tongue 15 is located eccentrically with respect to the center plane M of the panel-shaped element in which it is located, wherein the assembled element 1 is at least in the direction in which the tongue is displaced eccentrically. On the side, it forms an inner corner between the panel-shaped elements. More specifically, the tongue shown as a whole is located outside of the center of the panel-shaped element 1 in such a way that the tongue is located closer to the side located in contact with the inner corner 22 than the opposite side. do.

The tongue 15 is fitted in the recess 16 by a pivoting movement W as shown in FIG. 5, in which the pivoted panel-shaped element (in this case 2B) has its final position at a right angle. Get This pivoting movement W takes place along the side of the inner corner of the assembled element shown. Decomposition of both panel-shaped elements occurs by turning movement in the opposite direction, or by pulling or tapping the panel-shaped elements in a direction parallel to the tongue from each other.

It is noted that the panel-shaped elements can also be joined to each other by snap motion by displacing the panel-shaped elements by mutual translational motion, as shown in FIG. 4.

Here, the tongue 15 is fitted in the groove 16 by a snapping motion, such as forcing each panel-shaped element with the tongue 15 towards the groove 16 in its plane. In the illustrated embodiment, this fitting is achieved because the locking portion 17 can perform lateral elastic movement in combination with the slightest elastic compression possible in the material of the two locking portions 17, 18, and this method The locking portion 17 can engage the rear of the locking portion 18, all of which are independent of the combination with some further compression in the material of the tongue and groove.

The slit 23 preferably has a width equal to or greater than the maximum lateral displacement performed by the locking element 17 with respect to the panel-shaped elements to which the locking element belongs during mutual snap engagement.

Moreover, the inlet of the recess 16 has a small insertion angle A2, which angle is preferably less than 40 degrees, more preferably about 30 degrees.

As viewed as a whole, the tongue is made conical with a conical side formed by the outer side of the second part 22 and the outer side of the locking part of the first part 21.

The embodiments shown in the figures allow the tongue 15 and the groove 16 to be mutually coupled in two ways, not only by pivoting movements, but also by snapping movements through translational movements, and according to the installer's choice. It is apparent that the tongue 15 and the recess 16 are constructed. This is evident from FIGS. 4 and 5, which show two coupling techniques for the same type of tongue and groove, respectively.

As shown, the tongue 15 and the grooves 16 are preferably realized integrally in panel-shaped elements, for example by milling. Here, the tongue 15 is located on the small side of each panel shaped element, while the recess is provided on the side of each panel shaped element.

As shown in the figures, the panel-shaped elements are preferably formed of a coverDBoard, which preferably has covering layers 42 and 43 on both sides, respectively. This is preferred for melamine coated boards, and therefore for boards with laminated coatings. In particular, the laminated layer is made of at least a decorative layer provided with a resin and pressed onto the board, regardless of the combination with other layers. Examples are High Pressure Laminate (HPL) or Direct Pressure Laminate (DPL). In addition, a film, lacquer layer, or the like, or any other type of coating, may also be applied.

The basic board itself preferably consists of MDF, HDF or particle board. Particle boards are often not as stable as MDF or HDF, and are more easily crushed, but particle boards are lighter, which is chosen for aesthetic reasons, for example, to work with relatively thick walls of thickness 18 mm or more. Considering more important to, particleboard is preferred for furniture. The present invention contributes that such profiles may be implemented in the material of the particle board in an efficient manner.

On the edge portion, the panel-shaped elements can be provided with a finishing tape 44 such as, for example, a laminated tape or a finishing tape of synthetic material (eg ABS tape). 1 and 7 also allow the ends of the tongues and grooves to extend such a closing tape beyond the distal ends of the groove 16, in other words a straight tape in the same manner as described in DE 20 2009 008 825 U1. By providing a sheath, it can be concealed by such a finishing tape. Such tape coating is performed by the manufacturing company.

According to the second aspect of the invention, in the illustrated embodiment it is also supported in combination with a slit 23 which extends at least deeper than the protruding parts of the tongue, ie to a position beyond the closing surface 47. The particular distribution of (45,46) applies. Here, the first contact point is defined as a contact located closest to the closing surface 47 between the groove and the first portion 21 of the tongue 15, while the second contact point 46 is defined by the groove and tongue. It is defined as the contact located furthest from the closing surface 47 between the second portions 22. This particularity consists in that the first contact point 45 is located closer to the closing surface 47 than the second contact point 46. On the other hand, this results in a better distribution of force for the force in the bond. In addition, one panel-shaped elements are disposed with the grooves 16 facing upwards, while the other panel-shaped elements are provided with the tongue 15 facing downwards during assembly of one point of furniture. In the intermediate positions, it is obtained that the second panel is inclined very quickly and does not fall over even if left unattended.

In the engaged state, it is noted that the closing surface 47 generally consists of a surface coinciding with the panel surface 40 on which the end of the groove 16 is located.

As shown, on the inlet of the groove 16 on the side from which the tongue pivots into the groove, it is preferable that an angle cut 48 can be realized on the edge 49, which is further It enables a smooth turning-in.

The embodiment shown in the drawings also applies a third independent aspect of the invention. In that regard, the lengths of the first part 21 and the second part 22 of the tongue 15 are denoted by L1 and L2, respectively, while the central part of the closing face 37 is in the surface of each board. The distance that is located is indicated by L3. According to the third aspect, the tongue 15 has a slit, the locking part 17 is on the outer side of the first part 21, while on the outside of the second part there is a less prominent locking part and In addition, it is preferable that even the locking part does not exist. According to still the features of the third aspect, the second part 22 of the tongue 15 protrudes from the closing surface 47 by a length L2, which length means that the first part 21 of the tongue 15 is closed. It is less than 0.75 times the length L1 protruding from 47. By emphasizing this ratio, as the relatively second part does not interfere excessively, on the one hand, the tongue can be smoothly swung in, while in the first part such engagement and locking can actually be realized. The advantage is that it is obtained. Also in this case proportionally less deeply located portions of the bottom wall of the grooves can be carried out at a shallower depth, thereby making the walls of the grooves very rigid.

The illustrated embodiment also shows, inter alia, that the slit 23 extends to a depth extending beyond the closing surface 47, and furthermore, the second part 22 of the tongue 15 is provided with locking surfaces ( 36, 37 show a fourth independent aspect of the invention in that it projects by a length L2 from the closure surface 47 which is less than 1.5 times the mean distance L3 spaced from the closure surface. Thereby, it is obtained that the distance which the 2nd part 22 protrudes is limited with respect to the position to which the 1st part 21 engages. By this limitation, the part 22 which protrudes excessively far is excluded from experiencing as inconvenience during the engagement. In order to ensure stable bonding, in this case the length L2 is preferably larger than L3.

In the illustrated embodiment, in particular, the portion of the first portion 21 extending between the closing surface 47 and the locking surfaces 36, 37 exhibits an average thickness greater than the average thickness T2 of the second portion 22. As features are also shown, this embodiment also forms an example of the fifth aspect of the invention. By such a projection starting from the same overall thickness of the tongue 15, it is obtained that the first part 21 is made stronger and more stable, which means that this first part has a locking part and is therefore quite substantial for the force. Considering the fact that under load, it is obvious that it is important. It is evident that the fifth aspect is particularly advantageous in embodiments where the tongue is installed eccentrically and the slit extends deeper into the panel-shaped elements than the base of the tongue, as shown. Thus, by this, the first part 21 in this case extends so as to say the part of the cutout material of the panel-shaped elements with which this first part 21 comes into contact, although the first part is thus more stable It is obtained that is strong and yet nonetheless significant elasticity can be produced.

T1 is preferably the thickness measured in the middle of the length L and / or the average thickness of the portion extending over the distance L1, while T2 is in the middle of the average thickness and / or length L2 of the second portion 22. Note that it is the thickness measured. Possibilities can be applied according to the criteria the manufacturer wishes to use.

According to the sixth aspect, the depth L4, in other words, the distance L4 from which the slit 23 extends from the closing surface 47 toward the inside of the panel-shaped element 2 is greater than the maximum distance L1 from which the tongue 15 extends from the closing surface. long. It is clear that this is advantageous for the mobility of the first part 21. Moreover, the deformations issued thereby can be transmitted further backwards, so that the leading end of the first part 21 is subjected to a smaller load on the deformation at the position of the locking part.

According to the seventh aspect mentioned at the outset, the tongue and groove have a configuration in which the maximum of the force must be overcome when turning against each other towards the end of the pivotal engagement movement, and as a result also when turning back from each other, As indicated by the contact points 50, 51 of FIG. 6, here the force must be overcome, as in the case of the turning movement W, the contact is maintained adjacent to the edge portion 49. In this way, the retaining means or impeding means are integrated in the engagement itself, in which case the retaining means or impeding means are decelerating in opposition to the turning of the tongue and the grooves, and thus the panel-shaped elements, in mutually separate directions. At least providing the effect is obtained. At certain intermediate positions during assembly of the furniture, in order to prevent the collapse of one panel-shaped element, which in this case is provided upright temporarily in this case against another, in this case it is also during assembly useful.

As shown in FIG. 6, this provides a portion 52 on the side of the side where no locking portion is present, the portion 52 theoretically overlapping the portion 53 on the groove during turning in the direction of mutual engagement or separation, The result can be realized by allowing the dead point force, more preferably the deformation force, to be overcome.

Also in accordance with the alternative shown in FIG. 6, the tongue and groove at the height of the locking portions may include portions provided by the theoretical overlap 36A during pivoting so that the deformation force is overcome at dead point.

It is clear that both choices may or may not be combined.

In addition, the profiles can be implemented in such a way that the tension maintains in particular the so-called pretension.

It is evident that the coupling can be applied on various positions on the assembled element, such as furniture, in order to realize a corner connection of a general corner connection, a T-shaped connection, or even a cross connection. However, this does not mean that all corner connections of this assembled element 1 should be realized as such.

The present invention in particular provides for the tongue to provide such a bonding effect, so that the external elements in which the tongue affects on the tongue, such as wedges driven into the slit of the tongue, for example as known from US 7,654,055 It is noted that the purpose is for embodiments that remain in the absence. Indeed, such a tongue may comprise elements which remain fixed to the tongue and which can support the bonding force supplied by the tongue, such as mass provided in an elastic strip or slit in the tongue, for example. have.

Moreover, if desired, the invention is not limited to corner connections which may be applied to corner connections which extend in the horizontal directions in the assembled use state, but which extend in other directions, for example in the vertical direction. It is noted that. Embodiments of the connecting part extending in the vertical direction, which mean that the joining region extends in the vertical direction, are for example two side walls of the cabinet, similar to those shown in FIGS. 54 and 55 of DE 20 2009 008 825 U1 described above. Are obtained when they are connected to the rear wall by the corner connecting portion of the present invention.

The term "coupling zone" as applied above is to be understood here as part of a panel-shaped element from which said profile, for example a groove profile or a tongue profile, extends. Here, this is not only on the edges of the panel-shaped elements, but also on the edge areas, and therefore areas clearly spaced apart from the edges of the panel-shaped elements, for example for the purpose of forming a T-shaped bond between the panel-shaped elements. It may be related to an area located or located directly adjacent to the edge portion.

In addition, according to the present invention, the term "assembled element" is to be understood as an element in the state of "assembled" as well as the state of "unassembled". This means that in this case also the flat pack member of the furniture, which is yet to be assembled and still packed, for example showing one or more features of the invention in the assembled state, should also be considered as already assembled element.

When the term "intermediate piece" is used, it is an element applied on the corner between two panel-shaped elements, in which case each coupling is with at least one of the panel-shaped elements. Between the intermediate members. An example of the use of the intermediate member is shown in WO 2010/070605, for example in FIG. 64.

When it is mentioned that the side of the slit has a deflected orientation, this actually means an essential part of the side of the slit, and thus does not mean, for example, a curved portion, an inclined portion, or the like, of the leading or end of the slit.

It is also noted that a "locking surface" can possibly be understood as a line contact.

A side extending deflected from the main direction D1 may also be understood as a side having a stepped orientation. Also, for example, the sides 24 may extend parallel to the direction D1 over most of them to bend toward the surface 40 only adjacent to the deepest end of the slit.

It is obvious that embodiments according to the second from the seventh aspect do not necessarily have to have a tongue 15 with slits 23 extending obliquely. In such a case, for example, as indicated by the dashed-dotted line 23A in FIG. 3, the slits may extend parallel to each main direction D1, for example.

8 and 9 a first selection of the eighth aspect mentioned at the outset is shown. The illustrated assembled element 1 thus comprises at least three, in this case three or more, panel-shaped elements 2, which are to be mutually joined by corner connections 54, 55 and 56, 57. Can be. Here, the assembled element comprises corner connections with engaging parts, the engaging parts providing locking tongue and recessed connections. The “first” corner connections 54, 55 include joining portions that can be joined together at least by a snap-insert-movement, while such “second” corner connections 56, 57 ) Comprise engaging portions 56, 57 which can only be joined to one another by pivotal movement, so that these corner connections, ie corner connections 54, 55 and the other corner connections 56, are , 57) are different. It is noted here that the "first" corner connections 54, 55 as well as the "second" corner connections 56, 57 allow each tongue and groove to be joined to each other by pivotal movement. In FIG. 9, the difference is achieved by applying a split tongue 15 to each first corner joint 54, 55 and a full tongue 15 on each second corner joint 56, 57. Is realized.

A second selection is shown in FIG. 10, in which both corner connections, ie corner connections 54, 55 and the corner connections 56, 57 on the other hand, have a split tongue, the difference being described above at least. Preferably by substantially implementing these split tongues 15 differently, more preferably it is realized by the difference in the structure of the slits 23A, 23B of the split tongues 15.

In the embodiment of FIG. 10, the difference is realized by a combination of the following features:

The slits 23A, 23B of two different corner connections, so that the thinnest material portions between each slit and the closest sidewall always show different thicknesses (TA, TB), in this case TA is less than TB. Thus, one upper slit and the other lower slit are implemented;

Of two different corner connections, so that one slit 23 A extends deeper than the other slit 23B, that is to say have a different depth DA, DB, in which case DA is greater than DB. Slits 23A, 23B, thus an upper slit on one side and a lower slit on the other side are implemented;

The slits 23A, 23B of the two different corner connections, thus one upper slit and the other, so that the slits 23A, 23B extend at different angles XA, XB with respect to the panel-shaped elements. On the other hand, the lower slit is performed.

As a result, it is evident that the uppermost corner connections of FIG. 10 can be snapped together with each other with lower rigidity than those of the lower ones.

In the embodiments of FIGS. 9 and 10, the split tongues of both corner connections are of a type having a locking portion 17 only on one side of the tongue, more preferably on the part with the best mobility of the tongue.

8, 9 and 10 show that at least one of the panel-shaped elements, in this case the upper wall 6, is of a different panel-like shape by a snap insertion movement by the at least two corner connections 54, 55. Also shown is a feature that functions as a closing member 58 coupled to the elements, wherein these two corner connections are embodied as "first" corner connections, while a number of other corner connections in the assembled element ( 56, 57), in this case the remaining lowermost corner connections are realized as "second" corner connections. In the illustrated embodiment, it is evident that this provides the advantage that the lower corner connections can be carried out particularly firmly, while the upper corner connections allow for a smooth snap action.

It is noted that the above also applies to the T-shaped corner connection.

11 to 13 show a ninth aspect of the present invention. As described at the outset, a groove 56 is used that is substantially and preferably fully symmetrical when viewed in cross section here. As schematically shown in FIG. 12, this recess can be formed by a finger milling cutter 60.

The advantage of this technique is that the grooves 59 cannot be formed continuously, and at least at one end 61 in the material of the respective panel-shaped elements, such as for example in office furniture described herein below. It can be applied for applications that must have an end.

The office furniture shown is for the purpose of forming a connection between the side panels 62, 63, the top plate 64, and the side panels 62, 63 to keep the side panels 62, 63 in parallel. Intermediate portion 65 of the substrate. All the parts of this furniture are assembled entirely by locking profiles. During assembly, the side panels 62, 63 and the middle portion 65 are joined together by pivotal movement, wherein the tongues 15 located on the ends of the middle portion 65 are connected to the side panels 62, It pivots into a symmetric groove 59 located on the inside of 63. When the whole is standing upright, with the groove 16 positioned on the upper side of the tongue 15, the upper plate 64 is pressed downward on the upper edges of the side panels 62, 63. Can be.

The ninth aspect is also useful for a drawer in which one or more upstanding walls are assembled together by locking profiles. Here it is recommended that in certain applications practically no recesses are formed continuously, in which case symmetrical recesses 59 may be applied, and the end 61 of these recesses 59 may be located at a desired position. have. Many of these embodiments are described below.

It may also be useful in applications where such a symmetric groove is formed substantially continuously. Regardless of whether the symmetrical grooves are formed continuously or discontinuously, the advantage of such a symmetrical groove is that at least its contour and even the entire groove is realized in a single milling cycle, which saves money.

Another advantage is that these grooves are always the same, regardless of whether locking should occur on the left side of the groove or on the right. As different grooves are unnecessary, in certain applications, the operations required to realize the locking grooves can be significantly simplified.

It is noted that the tongues applied to the eighth or ninth aspect can always optionally include one or more features described herein for the split tongues, if these tongues are split tongues.

15 to 19 show respective specific parts of the assembled element 1 in the form of a drawer, where this assembled element meets the tenth aspect of the invention. Here, the assembled element 1 comprises panel-shaped elements 2E, 2F, 2G and 2H, which panel-shaped elements 2E, 2F, 2G and 2H are respectively the first of the drawer to be formed. It acts as side wall 66, rear wall 67, second side wall 68 and front wall 69, and in the combined form of the elements these walls form four corners, and the panel-shaped elements form corner connections. Interconnected by (70, 71, 72, 73). In the two rear corner portions, the corner connections 70, 71 each including the film hinge 74 are always used, while in the position of the front corner portions, the mechanical locking coupling portions 13, 14, more preferably Preferably corner connections 72, 73 with a locking tongue and groove connection are used.

As can be seen in the enlarged view of FIG. 17, it is preferable that such a film hinge is formed, while a continuous sheath 75 is provided on the adjacent panel-shaped elements 2F, 2g, while In other respects, the panel-shaped elements are separated from each other by suitable recesses 76. For the realization of this, it is preferable to start from the board provided with the sheath 75, in which case the recesses 76 necessary in this case are provided without cutting the sheath. This does not exclude that such a film hinge 74 is formed by, for example, another method, for example by collapsing a folDAble adhesive strip of a strip of hot melt adhesive. It is also not excluded to form joining parts such as to fit together or to be joined in another part within the sides 77, 78 of the one or more recesses 76 which are mutually joining, the joining parts being of the respective panel shape. The elements cooperate with each other as soon as they are pivoted towards each other along each film hinge.

These locking engagement portions 13, 14 can be of any kind, but these locking engagement portions 13, 14 are provided in the tongue 15 and the recess 16 having the locking portions 17, 18. It is preferably formed by. More specifically, these are preferably realized as described above, in which case it is irrelevant whether or not the slit 23 is used in the tongue, and when the slit is applied, such slit does not necessarily have to be inclined.

Therefore, all the component parts can be distributed in a flat state. To assemble the drawer, the panel shaped elements 2E, 2G are from the state of FIG. 15 to the state of FIG. 1 6. Here, the bottom 79 can be accommodated between the walls 66, 67, 68 in the grooves provided for this purpose. Thereafter, the front wall 69 is snapped downward using the grooves 14 on the tongue 13. On the rear side of the front wall 69, as shown in Fig. 18, a recess 80 is preferably provided, which forms a seat for the edge portion of the front face of the bottom.

In the illustrated embodiment, the front wall 69 forms a visible front panel, whereby this embodiment forms an application of the eleventh aspect. However, according to a variant, the wall 69 can serve as a simple front wall, while in this case it is clear that an additional separate front panel is provided in front of it.

20 and 21, a variant of the tenth aspect is shown, wherein all four walls 66, 67, 68, 69 are interconnected by film hinges, in which case the corner connections 70, 71, 73 are formed by film hinges, while the corner connection 72 is achieved by locking engagement portions 13, 14 located adjacent the free ends of the walls 69, 66. As shown by the dotted lines, additional front panels may be provided in contact with the front wall 69.

FIG. 22 shows another embodiment wherein the front wall 69 realized as a front panel is in this case directly connected to the side panels by at least one locking engagement, although in this case two locking engagements, This embodiment satisfies the eleventh aspect of the present invention.

23 shows a twelfth aspect of the present invention. The peculiarity of this is that the corner connection is realized with the locking coupling parts 13, 14, which in this case is combined with the adhesive connection which is the adhesive connection by the adhesive 84. In the illustrated embodiment, the adhesive 84 has two functions. The first function is to realize an additional connection between the two panel shaped elements since the adhesive is provided between the tongue and the groove. The second function fixes the two parts 21, 22 to one another by curing the adhesive 84, and in particular by the presence of the adhesive in the slit 23, the parts 21, 22 after curing of the adhesive It is difficult to move toward, resulting in a stronger bond. According to variants not shown, it is clear that the adhesive can also be applied in a position where only the first function or only the second function can be satisfied.

24 to 28 relate to a thirteenth aspect of the invention, or at least an embodiment of its essential component parts. 24 shows a fixed panel or cabinet of a cabinet having an assembled panel, for example a panel of a cabinet, for example a frame 85 consisting of frame panels 86, 87, 88, 89 located in the same plane. Mainly showing the door panel. Within the frame 85 is a center panel 90, which is seated in a rebate 91, such as grooves inside the frame panel 86, 87, 88, 89. The singularity of this consists in that the frame panels may be mutually coupled by the locking coupling 92, as can be seen in FIG. As can also be seen in FIG. 28, here, for example, the locking engagement portions 13, 14 described above can be used but other types of engagement portions are not excluded. It is actually important that this relates to the engaging parts which can be pressed against each other by the snap movement 93.

As schematically shown in FIGS. 24 to 27, the tongue 15 and the grooves 16 are preferably present locally at the respective edges to be joined, that is to say do not exist over their entire length. The tongue 15 and the grooves 16 are thereby invisible at the outer edge of the frame.

29 and 30 show a fourteenth aspect of the present invention. At this corner connection, profiles 94 and 95 with locking engagement portions comprising the tongue 15 and the recess 16 are used; The whole here comprises auxiliary means for assisting in the correct interassembly of the panel-shaped elements, which auxiliary means are formed by three-dimensional shaped elements in the form of protrusions 96 which can cooperate with corresponding recesses 97. Become; The projection 96 seen in the cross-sectional direction on each profile extends in the form of a plug which fully or mostly preferably protrudes through the profile 94 of the tongue, while the recess 97 defines the groove 16. It is provided with a singular point which is located in the panel-shaped element to include, and preferably implements in the form of a bore.

In FIG. 29, the protrusion 96 has a diameter slightly larger than the thickness of the tongue, and when the protrusion is positioned opposite the recess 97, the panel-like elements can thereby be joined together entirely. In FIG. 30, the protrusions extend further in the distal direction than the tongue 15, as a result of which the panel-shaped elements can also be joined together when the protrusions are located opposite the recesses 97. There is only. The depicted positions of the protrusion 96 relative to the tongue 15, in which the protrusions 96 are completely or approximately completely positioned at the position of the tongue, are made especially thicker for the panels to join such protrusions. It is obvious that it offers the advantage that it does not have to be. Conversely, this also means that it is particularly suitable that this form of integration is applied in thin panel shaped elements, for example less than 15 mm.

In the embodiments of FIGS. 29 and 30, both such protrusions 96 and associated recesses 97 have the same or approximately the same diameter. In this case, these correlated panel-shaped elements may be joined together by translational motion alone. This does not exclude that the fourteenth aspect may be applied to panel-shaped elements that can be joined together by other movements, for example pivoting movements. For example, in FIGS. 29 and 30, in order to allow the panel-shaped elements to still pivot, each projection 97 is tilted in the recess 97 during entry into the recess. In such a manner that tilting may be performed, the recesses 97 may simply be formed slightly wider in the transverse width of the recess than in each of the associated protrusions 96.

Coupling parts in "mechanical locking coupling parts" results in locking in the assembled state, thus providing that the panel-shaped elements cannot be separated from each other without overcoming a certain force in their normal assembled mutual state. It is obvious that it should be understood.

Thus, not only the features of the profiles shown in the figures, thus the tongue profile and / or groove profile, but all of the above-described features of this specification do not contradict the central meaning of such an independent aspect as such features or combinations of features. Each may be applied alone or in any possible combination with any of the fourteen independent aspects. Thus, some of these features, which may be optionally combined, are for example the following:

The tongue comprises two parts 21, 22 whether or not separated by a slit 23, one of which is shorter than the other;

The tongue is provided with slits 23;

The shape of the tongue and / or groove meets any of the dimensional proportions described herein;

The tongue can pivot into the groove;

The tongue can be snapped into the groove by a translational movement;

The tongue is located eccentrically;

The tongue is divided and the slit extends inclined with respect to the plane of the panel-shaped element;

The tongue comprises two parts 21, 22, whether or not separated by a slit 23, one of these parts 21, 22 being shorter than the other, 17) is provided only for the longest part (21).

In general, it is noted that in all the above-described aspects, the joining portions 13, 14, which preferably comprise the joining portions 17, 18, are preferably formed integrally with the material of the panel-shaped elements. Here, it may be related to any material. However, in most applications wood based panels with wood based substrates such as MDF, HDF or particle board are used.

The invention also relates to a separate component part for realizing the assembled element according to the invention, for example the side wall of a cabinet or drawer.

The invention is not limited to the embodiments described as examples and shown in the drawings, but rather to the realization of the above-described aspects realized according to the assembled elements, more preferably various modifications without departing from the scope of the invention. It may be parts of the assembled elements that provide.
