reference will now be made in detail to the present preferred embodiment of the invention , an example of which is illustrated in the accompanying drawings . the support and clamp part 1 shown in fig1 has a horizontal support surface 2 for a shelf ( not shown ), a shelf engagement region 3 , and a fastening head 4 . under the support surface 2 , the support and clamp part 1 is a hollow body which is open at the rear and , as can be seen in the sectional representation shown in fig1 has in side view an approximately triangular shape . as shown in fig2 the hollow body also tapers downwards with respect to its width , so that a rounded tip 5 is formed . the horizontal cross - sectional profile of the support surface 2 can be seen in fig3 . in the shelf engagement region 3 , two holes 15 for wall fastening screws are provided one above the other . in the fastening head 4 , a vertical hole 6 is left as a vertical guide for a shelf clamp screw 7 , which is illustrated in fig4 . in addition , the fastening head 4 has a recess 8 in which a nut 20 ( see fig1 ) fitting the clamp screw 7 can be non - rotatably received . consequently , it is not necessary to provide a screw thread for the clamp screw 7 in the fastening head 4 . the clamp screw 7 does not have a widened head so that it can be screwed completely into the hole 6 . the widened clamp foot 9 shown in fig5 can be fastened at its foot end ( not numbered ). finally , two guide bosses 10 are formed on the fastening head 4 . the bracket according to the invention is completed by a cover part 11 , which is shown in fig6 to 8 . like the lower portion of the support and clamp part 1 , the cover part 11 is a hollow body open at the rear and has the same or similar external shape as the lower portion . the bracket has a recess 13 , by means of which the cover part 11 can be engaged in the style of a shoe onto the widened clamp foot 9 as shown in fig5 . finally , a narrow rib 14 is also formed in the interior of the cover part 11 to cooperate with the previously mentioned bosses 10 on the fastening head 4 of the support and clamp part 1 . the wall shelf unit as described above is simple to assemble . preferably , the clamp screw 7 is already preassembled by means of a nut 20 inserted into the recess 8 and is also provided with the clamp foot 9 . the support and clamp part 1 can therefore be quickly attached to the wall with the aid of one or two fastening screws . as soon as another , identical support and clamp part has been installed at the same height and at a distance therefrom , a shelf can be inserted into the shelf engagement region 3 and fixed therein by tightening the clamp screw 7 . shelves of different thicknesses can obviously be used . it is then only necessary to attach the cover part 11 , by means of its base part 12 in the form of a shoe , onto the clamp foot 9 of the clamp screw 7 to complete the visual appearance . through the fastening of the cover part 11 on the clamp foot 9 of the clamp screw 7 , the vertical height of the cover part is dictated by the position of the clamp screw 7 . despite different shelf thicknesses , the cover part 11 always makes a good fit with the upper face of the shelf . the cover part 11 is simply supported on the fastening head 4 by use of the aforementioned rib 14 , which engages slidingly between the likewise aforementioned guide bosses 10 . the bracket according to the invention , completely assembled and with a shelf 16 clamped in position , is shown in fig9 . in the assembled state , the bracket according to the invention , excluding the shelf engagement region 3 , has approximately the shape of a slender boat body . both the support and clamp part 1 and the cover part 11 are preferably injection moldings , preferably of a plastics material , such as polyamide . the support and clamp part 1 and also the cover part 11 preferably project from the wall approximately twice the maximum height h of the shelf engagement region 3 . the overall height of the bracket , determined by the support and clamp part 1 together with the cover part 11 , preferably is approximately equal to eight times the maximum height of the shelf engagement region 3 . the maximum width of the support and clamp part 1 and also of the cover part 11 preferably corresponds approximately to the maximum height h of the shelf engagement region 3 . it will be apparent to those skilled in the art that various modifications and variations can be made in the bracket of the present invention without departing from the spirit or scope of the invention . thus , it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents .
a bracket for fastening shelves of various thicknesses to a wall comprising a support surface , a clamp opposite the support surface for pressing the shelf against the support surface , a shelf engagement region located between the support surface and the clamp for receiving the shelf , and a cover for concealing the clamp .
