Description
The invention relates to a body, in particular hollow body, which can be made up from individual elements having groove and tongue connections formed in the area oE the connecting surfaces, the tongues of which having flanks which converge away from the tongue base, and the grooves of which are complementary to the tongues.
Such a body is known from European Offenlegungsschrift 1 836. The knownbody is made from elements held together by clamping bands which abut the body from the outside. These clamping bands are unattrac-tive to look at and must therefore often be concealed under covering strips. This is not only expensive but is frequently impracticable such as in the case of furniture making.
The object of the invention is to improve a body of the above described type which can be made up from individual elements in such a way -that the elements hold together without additional holding or accessory means outside the connecting points.
The invention provides a body comprising individual elements having connecting surfaces formed with at least one groove and tongue connection; said connection being releasable in that a tongue can be pulled out of a groove transverse ts the longitudinal direction of said groove if a specific tractive ~ ~ 20 force is applied; said tongue having convergent flanks and said groove being ; complementary to said tongue; wherein at least one flank of said tongue and said groove has recesses adapted to receive ribs formed on an interlocking flank ~ of sa~id groove or said tongue; wherein said ribs and said recesses have cross-; sections of part circular form.
~ ~ :
With such a construction the tongues are held in the grooves without any additlonal means outside the connecting points. The elements are thus securely held to one another without adhesive, clamping bands or any other holding means, the body not displaying any unevenness or unattractive points ~ :
- ' ''~; ' . : ' ~
on the outside or the inside. The elements can be secured to one another quickly and simply with low assembly costs and inexpensive production, and assembly can be carried out by the unskilled. It is impossible to assemble the body incorrectly.
In many cases, such as for example furniture making, it is frequently desirable that the body can be taken apart after assembly. It is therefore proposed to position the rib releasably in the recess to form a snapping mechanism Transferability of great forces and secure adhesion are guaranteed when the rib and recess correspond to one another in shape. This is also achieved and/or improved when tongue and groove each have a rib or recess on both flanks or side surfaces respectively. It is furthermore proposed that the ribs and recesses extend over the entire length of the tongues and grooves.
A high degree of movability of the elements relative one another with a sufficient amount of tightness is achieved when in assembled state at least one hollow area is formed between groove and tongue and the hollow area can be filled with a mass which can harden and/or is permanently elastic, or at east one elastic clamping band can be inserted therein. An elastic clamping ~ 20 band can be posi*ioned in the base of each groove and engaged by the back ; of the tongue.
It is further proposed that the groove and/or tongue be formed by ~ profiles which can be inserted or attached at the elements. A high degree of :~:

accuracy in the production of the connecting points as well as simplification in the construction of the elements is thus achieved, since the elements them-selves need not have exactly formed grooves or tongues which are matched to the corresponding groove or tongue of the other element.
The profiles can be fixed particularly easily in the edge surfaces or front sides of the elements by way of groove and tongue and can be composed of elastic material, in particular plastic, and are thus easy to manufacture and can achieve a high degree of tightness.
Continuous groove and tongue connections are also achieved in the corner areas in that in the area of the corners of the elements the tongue of one side edge surface passes into a groove of a narrow side or front edge surface and a groove of one side edge surface passes into a tongue of a narrow side or front edge surace. This favourably influences production costs and improves tightness and stability. After the elements have been assembled the grooves and tongues run continuously on several abutting front sides without change. In order to simpliy construction and make assembly easier it is proposed that these passing points run at an angle of 45 to the tongues and grooves.
For particularly reliable transer of force and a high degree of tightness it is proposed that the grooves and tongues are dimensioned such that ~the force exerted by one clamping member is substantially transferred ~; between the flanks of the grooves and tongues.
An easy to manage and self-centering fixture which is also particu-larly simple in construction is achieved, particularly in the case of windows ~ ~ and doors fixture points, by troughlike indentations which are trapezoidal in :::
~ ~ -3-...~.- -' cross-section and in which correspondingly shaped ribs are inserted whereby the side surfaces of the trapezium sides have toroidal ribs in longitudinal direction of the trapezoidal profile, said ribs locking into correspondingly shaped grooves of the trapezium side lying in abutment.
Embodiments of the invention are represented in the drawing and described in more detail below.

Figures 5 and 6 show fixture parts in longitudinal and transverse cross-section; and Figure 7 shows a representation in perspective and greatly enlarged of the fixture parts after being taken apart.
The body shown in Figure 1 has a wall element 1, on ~he inside sur-face of which a profile 2 is fixed along one side edge the profile 2 having two tongues 3 of trapezoidal cross*section and a groove 4 of trapezoidal O cross-section between the tongues. Tongues 3 and groove 4 have the same shape and cross-sectional size. Profile 2 is so deeply inset into the sur-face of the wall element that the base of the groove 4 is flush with the mside surface of the wall element 1.
A second wall element 5 thicker than wall clement 2 can be secured at :its front edge to the profile 2 and thus to wall element 1. A profile 6 : :

The profile 6 has two trapezoidal grooves 4 corresponding in shape and size to the tongues 3 of profile 2, whereby the grooves 4 of profile 6 form between them a tongue 3 which fits into groove 4 of profile 2.
Longitudinal recesses 8 with arcuate cross-section are arranged in the flank 7 of tongues ~ and groove 4 of profile 2, into which upon assem-bly recesses 8 lock correspondingly shaped ribs 9 on the flanks of the grooves and tongues of profile 6. In the same way a third wall element 10, similar to wall element 1 is lockingly fixed on the opposing edge of wall element 5.
The force necessary for the locking connection and the holding force depend on the size and type of recesses 8 and ribs 9 and on the material of profiles
Such a body is known from European Offenlegungsschrift 1 836. The knownbody is made from elements held together by clamping bands which abut the body from the outside.

Continuous groove and tongue connections are also achieved in the corner areas in that in the area of the corners of the elements the tongue of one side edge surface passes into a groove of a narrow side or front edge surface and a groove of one side edge surface passes into a tongue of a narrow side or front edge surace.

Embodiments of the invention are represented in the drawing and described in more detail below.
Figure 1 shows a section through three wall elements of a body set one next to the other with prof;les mounted thereon;
Figure 2 shows cross-sections through alternative profile forms;
Figure 3 shows a section similar to Figure 1 with detachable pro-files;
Figure 4 shows an isometric representation of four wall elements;
Figures 5 and 6 show fixture parts in longitudinal and transverse cross-section; and Figure 7 shows a representation in perspective and greatly enlarged of the fixture parts after being taken apart.
The body shown in Figure 1 has a wall element 1, on ~he inside sur-face of which a profile 2 is fixed along one side edge the profile 2 having two tongues 3 of trapezoidal cross*section and a groove 4 of trapezoidal O cross-section between the tongues. Tongues 3 and groove 4 have the same shape and cross-sectional size. Profile 2 is so deeply inset into the sur-face of the wall element that the base of the groove 4 is flush with the mside surface of the wall element 1.
A second wall element 5 thicker than wall clement 2 can be secured at :its front edge to the profile 2 and thus to wall element 1. A profile 6 : :
is carried on one front or edge of element 5 and is composed of strip material, : , , .

t3 as opposed to the solid profile 2, and is recessed into the edge so as to be completely flush, for which purpose recesses may be milled in the edge before-hand. The profile 6 has two trapezoidal grooves 4 corresponding in shape and size to the tongues 3 of profile 2, whereby the grooves 4 of profile 6 form between them a tongue 3 which fits into groove 4 of profile 2.
Longitudinal recesses 8 with arcuate cross-section are arranged in the flank 7 of tongues ~ and groove 4 of profile 2, into which upon assem-bly recesses 8 lock correspondingly shaped ribs 9 on the flanks of the grooves and tongues of profile 6. In the same way a third wall element 10, similar to wall element 1 is lockingly fixed on the opposing edge of wall element 5.
The force necessary for the locking connection and the holding force depend on the size and type of recesses 8 and ribs 9 and on the material of profiles
2 and 6. Sufficient elasticity is produced by plastics profiles.
In addition to the locking connection of the profiles to one another a clamping band 11, belt or cable, in particular of steel can abut around the body on the o~tsides at the level of wall element 5. The clamping band 11 presses the wall elements against one another and is recessed in outer grooves formed from U-shaped profile strips 12 inset in the wall elements.
These profile strips can be closed on the outside by covering strips 13.
As shown in Figure 2, the two profiles 2a, 2b which attach to one another can also both be constructed as solid profiles or both be composed of strip material: see profiles 2c and 2d in Figure 2. ~hen assembled the pro-files 2c and 2d fo~m longitudinal cavities 14 between the mating groove base and tongue into which cavities 14 elastic beads 15, in particular of plastics, can be laid. The elasticity of these beads 15 or cords is considerably great-er than that of the profiles.
' '. ~ .

In the embodiment shown in Figure 3 the grooves and tongues have approximately semicircular cross-sections and a cavity 14a between the profiles 2a, 2b extends over the major part of the profile width so that the profiles abut one another only on two outer side flanks. This cavity permits limited movement of the wall elements in relation to one another and can contain an elastic bead 15 or cord or can alternatively be filled with a hardenable and/
or permanently elastic plastics mass or foam. This is introduced through a channel formed by a bore 16.
Since the profiles in the embodiment shown in Figure 3 abut one another only on their outer flanks, ribs and recesses are provided only in these outer areas. In the embodiment shown in Figure 3 the recesses 8 and ribs 9 have arcuate cross-sections.
If sealing is unnecessary as, for example, in furniture making, it is also possible to attach only short profile strips to the side elements which also need only run at the height and depth of a side element and never-theless have a high degree of form stability.
It is, however, also possible to mount corresponding shaped parts (groove tongue angle) with a tongue exchange according to Figure 4 in all corner areas. The tongue exchange is explained in further detail below in conjunction with Figure 4.
Of the two wall elements shown in Figure 4 wall element 5 has two edge surfaces 21 and 22. Two grooves 4 between which a tongue 3 extends run ~; , .
along one narrow edge. Half tongues 3a are positioned towards the surfaces 21 and 22 respectively, extend on their outer sides into the side surfaces 21 or 22 and each have about half the cross-section of a full tongue 3. The grooves, tongues and half tongues also run on the adjacent edge surfaces bordering the corner areas in the same construction and arrangement.
The other wall element 10 also has two side surfaces 27 and 28. Two tongues 2, between which a groove 4 extends, are disposed in the edge surface above side surface 27 along one longitudinal edge of wall element 10. Half grooves 4a are disposed outside of the two tongues 3; these half grooves 4a each have about half the cross-section of a full groove 4 and correspond in arrangement and dimension to the half tongues 3a. The lower groove 4a here in fact is only composed of a free space.
The vertical edge surface of the wall element 10 extends to the level of the side surface 21 of the wall element 5 after the wall elements have been assembled.
Wall element 10 has two grooves 4b on the front vertical edge surface between which a tongue 3b runs. A half tongue 3c is positioned adjacent each side surface 27 and 28.
In the corner area the left-hand half tongue 3c passes into the half groove 4a ~which is present only in theory) whereas the tongu~ 3b is cut off obliquely at the end in its upperJ approximately hori~ontal part so that the back of tongue 3b mests the base of groove 4 approximately at a right angle.
The same applies to the interaction of the backs of tongues 3 against the bases of grooves 4b. These transition points all extend obliquely at an angle of 45.
The base of the upper half groove 4a likewise intersects at right angles the back of the half tongue 3c.
.. ' Tongues 3 and grooves 4 correspond in dimension in such a way that a cross-section portion 35 remains free in each case between the back of a tongue 3 and the base of a groove 4, and a band seal (not shown) can be in-serted into the cross-section portion 35.
All the grooves,~half grooves, tongues and half tongues each have an approximately trapezoidal cross-section and are dimensioned such that a force pressing wall elements 5 and 10 against one another in the connecting direc-tion is substantially only transferred to the groove and tongue flanks. Only an insubstantial part of this force serves to press together the seals which are inserted in the cross-section portion 35.
Wall elements 1 and 10 stand on a base 23 which has two tongues 3 with a groove 4 therebetween which run all around at the edges on its upper side.
Two-part fixture elements can be used as shown in Figures 5 to 7.
These fixture elements are constructed according to the groove-tongue principle and have a receiving part 29 with a tToughlike indentation which is trapezoi-dal in both longitudinal and transverse cross-section, the inner walls converg-ing inuardly. An insert part 30 is self-centeringly pressed into this receiv-ing part, the insert part 30 corresponding in shape to the indentation of the receiving part 29, and completely filling this indentation. Ribs 31 are ~; moulded longitudinall~ on to the longitudinal sides or flan~s of the insert part 30, the ribs 31 locking into longitudinal grooves 32 of the receiving part 29. Receiving part 29 and insert part 30 are each secured in or on a frame and a covering surface or ledge with their base surface so that these parts can be releasably secured ~o one another. In the embodiment shown in ~ Figure 7 the part-cylindrlcal ribs 31a arranged obliquely to the dire_tion of ; fixture are provided on the inner walls in the receiving part 29 and the cor ~ - 8 -responding grooves 3~a are in the side walls of the insert part 30.
A longitudinal slot 33 (Figure 6) can be formed in the insert part 30 parallel to the ribs 31 and at right angles to the base side~ said slot 33 increasing the spring effect of the ribs or side surfaces ~flanks) of the insert part.
Through this construction groove-tongue profiles and further frames can be added as fixtures to existing structures without requiring the use of skilled labour.

In addition to the locking connection of the profiles to one another a clamping band 11, belt or cable, in particular of steel can abut around the body on the o~tsides at the level of wall element 5. The clamping band 11 presses the wall elements against one another and is recessed in outer grooves formed from U-shaped profile strips 12 inset in the wall elements.
These profile strips can be closed on the outside by covering strips 13.
As shown in Figure 2, the two profiles 2a, 2b which attach to one another can also both be constructed as solid profiles or both be composed of strip material: see profiles 2c and 2d in Figure 2. ~hen assembled the pro-files 2c and 2d fo~m longitudinal cavities 14 between the mating groove base and tongue into which cavities 14 elastic beads 15, in particular of plastics, can be laid. The elasticity of these beads 15 or cords is considerably great-er than that of the profiles.

In the embodiment shown in Figure 3 the grooves and tongues have approximately semicircular cross-sections and a cavity 14a between the profiles 2a, 2b extends over the major part of the profile width so that the profiles abut one another only on two outer side flanks. This cavity permits limited movement of the wall elements in relation to one another and can contain an elastic bead 15 or cord or can alternatively be filled with a hardenable and/
or permanently elastic plastics mass or foam. This is introduced through a channel formed by a bore 16.
Since the profiles in the embodiment shown in Figure 3 abut one another only on their outer flanks, ribs and recesses are provided only in these outer areas. In the embodiment shown in Figure 3 the recesses 8 and ribs 9 have arcuate cross-sections.
If sealing is unnecessary as, for example, in furniture making, it is also possible to attach only short profile strips to the side elements which also need only run at the height and depth of a side element and never-theless have a high degree of form stability.
It is, however, also possible to mount corresponding shaped parts (groove tongue angle) with a tongue exchange according to Figure 4 in all corner areas. The tongue exchange is explained in further detail below in conjunction with Figure 4.
Of the two wall elements shown in Figure 4 wall element 5 has two edge surfaces 21 and 22. Two grooves 4 between which a tongue 3 extends run ~; , .
along one narrow edge. Half tongues 3a are positioned towards the surfaces 21 and 22 respectively, extend on their outer sides into the side surfaces 21 or 22 and each have about half the cross-section of a full tongue 3. The grooves, tongues and half tongues also run on the adjacent edge surfaces bordering the corner areas in the same construction and arrangement.
The other wall element 10 also has two side surfaces 27 and 28. Two tongues 2, between which a groove 4 extends, are disposed in the edge surface above side surface 27 along one longitudinal edge of wall element 10. Half grooves 4a are disposed outside of the two tongues 3; these half grooves 4a each have about half the cross-section of a full groove 4 and correspond in arrangement and dimension to the half tongues 3a. The lower groove 4a here in fact is only composed of a free space.
The vertical edge surface of the wall element 10 extends to the level of the side surface 21 of the wall element 5 after the wall elements have been assembled.
Wall element 10 has two grooves 4b on the front vertical edge surface between which a tongue 3b runs. A half tongue 3c is positioned adjacent each side surface 27 and 28.
In the corner area the left-hand half tongue 3c passes into the half groove 4a ~which is present only in theory) whereas the tongu~ 3b is cut off obliquely at the end in its upperJ approximately hori~ontal part so that the back of tongue 3b mests the base of groove 4 approximately at a right angle.
The same applies to the interaction of the backs of tongues 3 against the bases of grooves 4b. These transition points all extend obliquely at an angle of 45.
The base of the upper half groove 4a likewise intersects at right angles the back of the half tongue 3c.
.. ' Tongues 3 and grooves 4 correspond in dimension in such a way that a cross-section portion 35 remains free in each case between the back of a tongue 3 and the base of a groove 4, and a band seal (not shown) can be in-serted into the cross-section portion 35.
All the grooves,~half grooves, tongues and half tongues each have an approximately trapezoidal cross-section and are dimensioned such that a force pressing wall elements 5 and 10 against one another in the connecting direc-tion is substantially only transferred to the groove and tongue flanks. Only an insubstantial part of this force serves to press together the seals which are inserted in the cross-section portion 35.
Wall elements 1 and 10 stand on a base 23 which has two tongues 3 with a groove 4 therebetween which run all around at the edges on its upper side.
Two-part fixture elements can be used as shown in Figures 5 to 7.
These fixture elements are constructed according to the groove-tongue principle and have a receiving part 29 with a tToughlike indentation which is trapezoi-dal in both longitudinal and transverse cross-section, the inner walls converg-ing inuardly. An insert part 30 is self-centeringly pressed into this receiv-ing part, the insert part 30 corresponding in shape to the indentation of the receiving part 29, and completely filling this indentation. Ribs 31 are ~; moulded longitudinall~ on to the longitudinal sides or flan~s of the insert part 30, the ribs 31 locking into longitudinal grooves 32 of the receiving part 29. Receiving part 29 and insert part 30 are each secured in or on a frame and a covering surface or ledge with their base surface so that these parts can be releasably secured ~o one another. In the embodiment shown in ~ Figure 7 the part-cylindrlcal ribs 31a arranged obliquely to the dire_tion of ; fixture are provided on the inner walls in the receiving part 29 and the cor ~ - 8 -responding grooves 3~a are in the side walls of the insert part 30.
A longitudinal slot 33 (Figure 6) can be formed in the insert part 30 parallel to the ribs 31 and at right angles to the base side~ said slot 33 increasing the spring effect of the ribs or side surfaces ~flanks) of the insert part.
Through this construction groove-tongue profiles and further frames can be added as fixtures to existing structures without requiring the use of skilled labour.
