BRIEF SUMMARY
FIELD OF THE INVENTION
This invention pertains to a variable furniture construction system and more in particular to a wooden (dis)mountable, variable furniture construction system that, in mounted condition, comprises at least two vertical stands, each consisting of a pair of columns, said system further comprising a number of in height adjustable trays, which in mounted condition are lying horizontally, said trays being carried at their ends by detachable supporting beams attached to the stands.
BACKGROUND OF THE INVENTION
Until the present a number of different such-like construction systems have been proposed. These on the one hand have the disadvantage that for mounting use is made of, from the outside clearly visible, esthetically unsightly metal parts and/or series of bore holes, as a result of which the mounted system is less suited to be applied for a true furniture function. On the other hand such systems consist of components connected to each other thus that an insufficient sturdy construction is achieved, which more in particular in the long run proves not to endure the normally occurring heavy stress. If the known system is used for books, a sufficiently sturdy mounted system can be realized only by additional means requiring a rather complicated and elaborate mounting.
Subsequently there is still demand for a simple and financially attractive system of a predominantly wooden furniture construction which is easy to mount and dismount, that is truly acceptable from an esthetic point of view as a piece of furniture thanks to the lack of visible unsightly metal parts and/or series of bore holes.
SUMMARY OF THE INVENTION
Purpose of the invention is therefore to provide a financially attractive and easy to mount, variable furniture construction system, that moreover meets the demand described in the above. According to the invention such a predominantly wooden furniture construction system is distinguished in that each profile column provided on the inward facing side with a groove in the longitudinal direction, in the bottom of which a number of mutually spaced pin holes have been made into which pins of distance blocks fit, whereby each time on two opposite distance blocks attached at similar height, a supporting beam is positioned, on which one end of a tray rests, whereby each supporting beam is provided on the side directed to the thereupon resting tray, with recessed pin holes or protruding pins, while in the surface of the place-tray in the place of these pin holes or protruding pins respectively corresponding fitting pins or pin holes are provided in order to strengthen the mounted system further on.
DESCRIPTION OF THE DRAWINGS
FIG. 1 shows in perspective the upper portion of a stand, comprising two profiled columns and one end of a tray.
The FIGS. 2-4 are a partly exploded view of the upper portion of one column, partly cut-out with a small part of a side panel and a back panel.
FIG. 5 is a perspective front view of a portion of a tray.
FIG. 6 shows a supporting beam with a separate wing-shaped sideward extension.
The FIGS. 7 and 8 show two opposite distance blocks for carrying a supporting beam.
The FIGS. 9-11 show three different views of an integrated combination of a supporting beam having on both sides a wing-shaped extension.
The FIGS. 12-15 are four different embodiments of a column belonging to a vertical stand.
DESCRIPTION OF PREFERRED EMBODIMENTS
As can be seen from FIG. 1, a stand 13 for the present furniture construction system is composed of two spaced profile columns 1, interconnected at the top by a cross-beam 2. At the invisible bottom of the stand 13, there is another cross-beam. Each column 1 has a longitudinal groove 3 into which the cross-beams 2 are secured. FIG. 3 shows a number of spaced holes 4 in the bottom of the groove 3. Into these holes 4 a pin 5 of a distance block 6 (shown in FIGS. 7 and 8) may be inserted. Upon a pair of blocks 6 mounted into the grooves 3 of two spaced columns 1 belonging to the same stand 13, both blocks lying on the same lev
