fig1 and 4 show the assembly principle for the individual elements 11 , 13 , 19 . supporting bars 1 or 1a are secured to the kitchen floor at a distance from the walls . these supporting bars are disposed in vertically adjustable holders 2 . suspension bars 3 are secured to the walls in holders 4 . the bars 3 disposed at an accurately determined distance h above the upper edge of the supporting bar 1 ( see fig1 and 2 ). the structure of the supporting bar 1 or 1a and the suspension bar 3 will be described in further detail hereinafter . two parallel profile bars 1 and 1a are disposed along the walls on which only elements resting on the ground , for example , under - counter cabinets 11 , stoves , etc ., are to be arranged ( fig1 ). if only tall cabinets 19 are to be installed along a wall , it is only necessary to provide a single supporting bar 1 . the tall cabinet 19 is then secured to this supporting bar and to the suspension bar 3 ( fig2 ). wall cabinets 13 are only suspended on the suspension bars 3 . on the underside of their rear wall the wall cabinets are provided with adjustable , horizontal spacing elements 5 for example , adjusting screws , which facilitates accurate vertical adjustment of the cabinets . all the elements to be installed are mounted at a distance a from the wall ( fig1 and 2 ). in this way it is possible to set up the kitchen units without regard to the existing drainage lines 6 or to the position of water main connections 7 , current connections , telephone connections , ventilation lines , etc . corresponding connection lines can be installed in the space a . the breadth of this space can be designed to suit the particular requirements . however , the intermediate space a also meets another requirement . as the individual elements to be incorporated have been manufactured according to a precise scale , in the assembled state , their total length and width will always correspond to a complete multiple of the scale division . the kitchen units can now be combined as desired as represented in the floor plans shown in fig1 a - 10d . as the spacing of the kitchen walls seldom corresponds exactly to the dimensions of the installed elements , the intermediate spaces a also compensate for any variations in length and breadth and for any possible variations from the specified masonry measurements . in most cases , the kitchen units can be installed without using any adjustment pieces , thus saving considerable work . only with the layout shown in fig1 a is it generally necessary to secure a simple covering screen on one side . as is apparent from fig1 and 3 , the work surfaces 9 of the under - counter cabinets 11 are provided with an upwardly projecting flange 9a ( see fig3 ). the rear wall of the wall cabinets 13 is provided with a downwardly projecting extension flange 13a . a rear wall 15 which is provided with grooves corresponding to the flanges is suspended in the flanges 13a and 15a . this is pressed downwards by a number of springs 14 let into the upper groove . to remove the rear wall 15 , it is merely necessary to raise the same against the pressure of the springs 14 and then draw it forwards and downwards . electrical devices such as connection plugs , clocks , timers for the stove , etc . and holders 16 for small shelves and the like can be mounted on this rear wall . the structure of the supporting bar and the suspension bars 3 and their securing elements will now be described in further detail . the suspension bar 3 has a generally l - shaped cross - section ( fig6 ). at its upper and lower parts it is provided with flanges having a u - shaped cross - section which each define a longitudinal groove 3a , 3b . on its horizontal arm 3c , the suspension bar 3 is also provided with a vertical , upwardly directed flange 3d in which the holders 20 secured to the rear walls of the wall cabinets 13 or tall cabinets 19 are adapted to engage . the bar 3 is supported by two or more holders 4 . each holder 4 comprises a rear plate 21 which is screwed to the wall . it bears two plug bolts 22 , on each of which is disposed a disc - shaped retaining nut 23 ( see also fig6 a ). the disc - shaped part 23a which is provided with a groove 23b on its front side engages in the grooves 3a or 3b of the bar 3 . by turning the retaining nuts 23 , the desired spacing from the wall can be obtained . the bar 3 is then secured by means of the retaining nuts 25 . the bolts 22 are provided with notches 22a which represent breaking points . after the suspension bars 3 have been adjusted and secured in place , the projecting parts of the bolts 22 can thus be broken off at these breaking points . the supporting bars represented in fig8 and 9 consist of wooden strips 1 which are secured in holders 2 . the holders 2 comprise a base plate 26 which is screwed to the floor . two plug bolts 27 are rotatably mounted in the base plate 26 . these bear a holder 28 which comprises a u - shaped part 28a and two horizontal arms 28b . projections 28c on the arms 28b project into longitudinal grooves 1a of the strip 1 . by rotating the plug bolt 27 , the holder 28 can be vertically adjusted . pairs of guide strips 29 are attached to the underside of the under - counter and tall cabinets 11 and 19 . the strip 1 engages between these guide strips 29 . after the support bars and their holders have been mounted , they are covered with screens 30 . screens 31 can also be attached to the upper side of the wall cabinets 13 and to the tall cabinets 19 . as already stated , the support bars 1 and 1a and the suspension bars 3 are assembled by means of braces . these are represented in fig5 . the rightangled position of the support bar 1 is accurately engaged by the angle brace 32 . if the support bars 1 are perfectly aligned horizontally , for example , by means of a water level , a brace 33 is mounted which supports the suspension bar 3 in holders 33a so that this bar can be secured to the wall by means of the holder 4 at the exact distance h from the supporting bar 1 . the individual parts of the brace may be collapsible thus facilitating transportation of the same .
a kitchen cabinet , stove , sink , etc . installation including floor units 11 mounted on horizontal floor rails 1 , 1a , overhead cabinets 13 mounted on horizontal wall rails 3 , and full length cabinets mounted on both a floor rail and a wall rail . the installation provides for dead space a behind the cabinets for piping , electrical wiring , etc . removable splash boards 15 are installed between the floor units and the overhead cabinets , with the latter being held out from the wall by spacers 5 .
