DESCRIPTION OF THE PREFERRED EMBODIMENTS The mounting frame illustrated inf FIGS. 1 and 2 has a square baseplate 10 and four sidewalls 11,12,13 and 14. The outer side of each of the sidewalls extends upwards at right angles from the baseplate, while its inner wall is inclined in such t e top inner edges of th e sldewalls (FIG.2). Each of the sldewalls has two fastening elements 15,16 or 17, 18 or 19,20 or 21,22, which subdivide the side surface into three portions of equal length in its longitudinal direction and which are disposed halfway up the height of the sldewalls. The fastening elements consist of holes 16,18,20 and 22 and of pins 15,17» 19, and 21 projecting at right angels from the sidewall and prowided at their front end with a spherical thickened portion. A the height of the upper side of the baseplate, a slot 23 is also provided in the sidewall 13. The four outer edges are provided with notches 25,26,27, and 28 which extend parallel to the baseplate and which are disposed halfway up the height of the sidewall, their width corresponding to the diameter of the holes. The underside 29 of the baseplate is roughened by a pattern of intercrossing notches similar to a file.

The outer aide length of the mounting frame illustrated is 30.4 cm. and width of the sldewalls and their top end is 0.2 cm. , so that the free area encloed by the sldewalls is suitable for the insertion of square pieces having a side length of 30 cm. The inclination of the inner sides of the sldewalls is so selected that at their bottom end they have a minimum width of 0*17 cm. The thickness of the baseplate amounts to 0.1 om. and the total height of the sldewalls from tbe bottom to the top edge amounts to 0.9 om. The diameter of the hole provided as fastening element and the width of the notches provided at the edges amounts to 0.25 om. , while the diameter of the cylindrical portion of the projecting pin amounts to 0.28 cm. and the diameter of the spherical thickening provided at the end of the pin is 0.33 cm. The overall length of the pin amounts to 0.3 The notohes 25 » 26 , 27 »28 at the four corners of the mounting frame are provided for the insertion of projecting bolts, when the above described square mounting frame is for exam -pie to be joined to a rectangular mounting frame having a longer side length.

In FIG. 3 » adjoining sidewalls 11 * and 13 of two juxtaposed mounting frames are illustrated in section. The pin 15» which is made of a plastios material which is deformable under pressure, is pressed through the hole 20 and forms a durable but detachable fastening between the sidewalls.

In FIG. 4, nine assembled mounting frames 30*38 are illustrated, in which because of the above-described arrengement of the fastening elements a pin always encounters a hole and can be pressed into the latter independently of the selected mutual., position of the mounting frames, so that each mounting frame is detachably oonneoted on each side at two points to the adjoining mounting frame.

If desired, the pins on the outer sides of the mounting frame oan be broken off, in order that projecting pins will get in the way when it is desired to cover a large area.

If the pieces to be inserted into the mountin frames are easily deformable or elastio and have approximately the same thickness, they can be inserted into the individual mounting frames after the latter have been assembled. If the pieces to be inserted are not flexible or are very thin and if they are intended for mounting frames which are to be fastened on a wall or oeiling, these parts are advantageously but to a size which is slightly larger than the free area enclosed by the mounting frame and then inserted from the side through the slot 23 into the mounting frame. It is then also possible for additional un the ineerted pieoe in the mounting frame and to fill the entire depth of the latter.

I6.7.I968 FIG. 5 illustrates four mounting frames 50,51*52 and 53 of a surface covering. The mounting frame 50 ( and every other mounting frame) contains a baseplate 4- and four sidewalls, of whioh only theesidewalls 55>56, and 57 can be seen in the Figure. In contrast to the form of construction illustrated in FIGS. 1,2 and 5, in the case of these mounting frames the dpvioe for detachable fastening them together is in the form of a recess 58 disposed in:,the middle of each sidewall. Eaoh of the reoesses extends over the surface and the inner side of the sidewall and into the adjoining portion of the baseplate* In addition, a projecting pin 59 is provided in the portion of the recess situated in the baseplate. The two juxtaposed mounting . frames 50 and 51 are joined ¾rith the aid of a connecting element 60· The connecting element 60 corresponds in shape to the recesses innthe two juxtaposed mounting frames and is inserted into )said recesses. In each of its two projections 6l and 62, which are intended for insertion into the portions of the recesses which are situated in the baseplate, the connecting element has a bore into whioh the pins ? and 64 respectively are inserted in order to hold the connecting element op eaoh of the mounting frames.

The connection of two juxtaposed mounting frames with the aid of a connecting element is illustrated in FIG. , which is a sectional view taken along the line A-A in FIG.5» The Figure shows the two mounting frames 50» and 51* and the connecting element 60». As oan be seen from the Figure, in the region is facilitated, In addition, the pins 63 * and 64 » projecting upwards out of the portions of the recess which extend in the baseplates (for example the baseplate 54» ) can be seen, which are introduced into the bores in the projections 61 » and 62 » , in order to secure the connecting element more satisfactorily.

The above-described connecting element enables any desired number of mounting frames to be detachably seoured together rapidly and securely over any surface. Sinoe the shape of the connecting elements matches the reoesses in the mounting frames, the insertion spaoe of each of the mounting frames is bounded by continuous smooth interior walls, which is important for the insertion of pieces simply out to shape.

In order to ensure that the outer sidewalls of surface coverings composed of plurality of mounting frames will not have uncovered recesses, these recesses can be covered by half a connecting element, formed by dividing an element into two parts along the broken line 65 shown in .FIOV 6.

In FIG* 7 and edge piece 70 is shown, which is advantageously used as a side termination of surfaoe coverings, where a bevelled transition is desired between the surface to be covered and the surface oovering, as is the case particularly with floor coverings. The edge piece has a portion 71 which has a wedge-shaped section and whioh is at least as long as a sldewall of a mounting frame. The edge piece also has a fastening element 60 » shich is disposed in the longitudinal center of the wedge-shaped portion, its shape corresponding to a fastening element 60 symmetrically divided in its transverse direction, i.e. longitudinally of the sidewall.

It is obvious that the above-disoribed form of construction of the mounting frame can also be modified so that more than In the form of construction of a mounting frame which is illustrated in FIG. 8 , the recesses are in the form of notches 75» 76. These notches extend along the Joint between the baseplate 77 or 78 and the inner surfaces of the sidewall 79 or 80 respectively. A clip 81 which is made of elasticmaterial and which embraces the two sidewalls is uaed as connecting element.

In the embodiment illustrated in FIG. 9 » the mounting frame has reoesses 83 ,84- , and 85 in the form of blind holes. These blind holes are disposed at regular intervals along the edge between the baseplate 86 and the inner surface of the sidewall 87. In this embodiment juxtaposed mountiig frames are held together with the aid of springe 88 » 89 and 90 engaging in the blind holes. It is naturally also possible for the blind holes to be replaced by continuous bores and for a spirally wound connecting element to be used instead of the spring clips.

Another form of oonstruotion of mounting frames is illustrated in FIG. 10 , in whifih the recesses 91 and 92 practioally correspond to the recesses 75 and 76 shown in FIG. 8. In contrast to the embodiment illustrated in FIG. 8 , the mounting frames shown in FIG. 10 are oonneoted together by a connecting element in the form of a section bar 93* This seotion bar has a T-shaped cross section, while the outer ends of the oroas-beam have extensions 95 and 96 respectively whbh lead to the baseplate of the mounting frames and which have at their bottom inner ends projecting flanges 97 , 98 which engage in the recesses 91 and 92 repectively. The individual mounting frames are separated from one another by the vertical center the pieoes of material inserted in the mounting frames.

In the embodiment illustrated in FIG. 11, the recesses are in the form of channels 100, 101 open on one side and extending on the ouside of the sidewalls of the mounting frames, approximately halfway up their height and running in the longitudinal direction. The connecting element 102 fitting said channels is T- shaped and on its vertical central web is provided with two beads of approximately circular cross section.

In the embodiment illustrated in FIG. 12, two identical mounting frames 105 and 106, the shape of which corresponds to the mounting frames as already desoribed with reference to FIG. 10, are joined by a fastening element 107 whichitself is in the form of a mounting frame» The fastening element contains a baseplate 108 and sidewalls 109,110 which are pushed over the corresponding sidewalls 111 and 112 respectively of the two mounting frames 105 and 106 and fastened with the aid of the beads 113* 114 in corresponding recesses 115 and 116 respectively. It is obvious that the most important dimentions of this fastening element may be so select-fed that the latter can be inserted instead of a mounting frame between four mounting frames abutting by their outer edges. -l6.7«l?68.

The mounting frames are preferably made of plastios material, such as polystyrene, polypropylene, acryl, nylon, polyethylene, or of plastios material reinforced with glass or other materials, or of rubber, wood, metal or glass. They may be flexible, semi-stiff, or nonelastio. Instead of the &ove described hole, the fastening elements may comprise a threaded nut and the pin may be replaoed by an open-ended bore for a bolt, which is practical Finally, the baseplate may also be provided with one or more holes if the mounting frames are not laid horizontally but are to be fastened on a wall or ceiling without the use of rails or adhesive plastios. Instead of roughening the underside of the baseplate plate by scoring, the underside may also have a nonslip layer applied or adhesively bonded to it. The shape of the mounting frames is also not restricted to the above-described square shape, and any shapes which can be assembled to form larger areas may be used, such as triangles, rectangles, parallelograms, hexagons, and shapes derived therefrom by reotillinear parts. The possibilities of assembly are not limited to identical shapes , but different shapes may also be assembled, provided that dimensions adjusted to one another are used for all shapes and that the distances between the fastening elements are always the same.

Thus, particularly when using mounting frames of different shapes, it is possible to produoe coverings for large surfaces in any desired pattern, which are secured against mutual displacement but can be ohanged or removed at any time.

Moreover, the edges of the individual parts of the covering which are to be inserted are therby effectively protected against wear, and parts of different thiokness oan be raised by the use of icompensating pieces inserted between the inserted parts and the bottom plate of the mounting frames, in order to form a large flat surface, and finally through the fastening of individual mounting frames together, the nonslip surface on the underside of the mounting frames can prevent the displacement of the covering, particularly in the case of floor coverings.

It will be appreciated that other modifications may be made
