Description
Background of the Invention
1. Field of the Invention
This invention relates to a shelf, shelf system or partition according to the introductory clause of claim 1.
2. Description of Related Art
In such a shelf system known from DE-A-22 39 239, the U-shaped module units have, at the narrow sides that end exposed, two notches each in the shape of a segment of a circle whose height is less than the radius of the associated circle. In each case, a connecting element in the form of a pin with a central recess whose radius corresponds to that of the notches and whose width is matched to the wall thickness of the module units can be inserted into the notches. By putting two module units atop one another so that their narrow sides that end exposed are opposite one another, the corresponding notches of both module units form a segment of a circle the size of the recess parts of the connecting elements. Both module units are thus kept at a short distance from one another and are fixed in position laterally forward and rearward.
With this known system, out of each two module units with adjacent narrow sides, shelves can be made by placing such two-piece units with their base parts atop one another or with their side walls next to one another. A connection of two-piece units put atop or next to one another is not anticipated. Larger, in particular high shelf walls of this design are thus unstable and additional measures must be taken to prevent the shelf from wobbling, swaying or even collapsing under greater loads.
With this invention the object to be achieved is that a shelf, shelf system or a partition of the type mentioned is to be configured so that a rigid connection of the individual module units is guaranteed when stacked on one another and with assembly next to one another. The shelf, shelf system or partition is also to have great stability even under greater loads. Further, the shelf, shelf system or partition is also to be able to be produced if possible of commercially available, in particular environmentally friendly, material.
This object is achieved by the features of claim 1.
Because of the special configuration and arrangement of the blind holes and the connecting elements provided, an efficient, precise and nonslip assembly is guaranteed without additional aids and simultaneously numerous shelf arrangements are made possible since the module units can be used in different positions.
The assembly of the shelf, shelf system or partition can further be performed quickly without special knowledge. Despite this, great stability and thus also a great load-bearing capacity are made possible for such a shelf, shelf system or partition.
It is true that it is known from DE-A 26 07 210, to produce prefabricated furniture of box-type design, to provide all four surfaces of square panels of laminated wood with several blind holes offset relative to one another and to chamfer the end faces on both edges by 45.degree.. Pegs bent at an angle are used there as connecting elements. To make a stable shelf or a stable cabinet wall, numerous connecting elements are necessary, since with one connecting element only one anchoring in one direction is possible in each case, while an anchoring in two directions is always required.
Brief Description of the Drawings
Other advantageous details of the invention are indicated in the subclaims and will be described in more detail below based on the embodiments illustrated in the drawing.
There are shown in:
FIG. 1, a perspective view of a U-shaped module unit with connecting elements in an exploded representation,
FIG. 2, a front view of module sections in the area of their respective connections,
FIG. 3, the perspective view of a carrying panel and
FIG. 4, a view of a shelf with module units that can be used in various ways.
Detailed Description of the Preferred Embodiments
In FIG. 1, 1 represents a module unit in a U-shape. It consists of a base panel 2 with carrying uprights 5 provided on lateral ends 3 or 4, perpendicular to base panel 2.
On exposed, narrow side 6 of carrying uprights 5, at least two blind holes 7 are provided whose central axes 8 run perpendicular to base panel 2. They preferably lie on or in the area of center line 9 of narrow side 6 and are placed as far as possible from one another. Optionally, blind holes 7 can be reinforced with a stiffening sleeve 10 to increase stability, as can be seen in FIG. 2.
In an extension of central axis 8 of blind holes 7 on narrow sides 6 of carrying uprights 5, analogous blind holes 7 are also placed on opposite side 11, which also forms the outer side of base panel 1, as can be seen more clearly based on the section according to FIG. 2.
Peg-shaped connecting elements 12 are used to connect module units 1 to be placed atop one another. They have an upper and lower peg or pin 13 or 14 and a spacer collar 15 molded on centrally, movably or pushed into the press fit. Pegs or pins 13, 14 can also be inserted, pressed or screwed into correspondingly shaped openings of spacer collar 15.
When spacer collar 15 has a round shape, its outer diameter 16 is at most as large as wall thickness 17 of carrying uprights 5. Spacer collar 15 can also be made as a square or rectangle, and then its width corresponds at most to the thickness of wall 17.
H-shaped connecting elements 18 are provided to connect module units 1 that are to be arranged next to one another. H-posts 19 made of them are made corresponding to peg-shaped connecting elements 12 and thus have a central spacer collar 15 and pegs or pins 13, 14 that project upward or downward. Both spacer collars 15 are rigidly connected to one another, for example by a spacer bar 20 that is molded on, pressed in or screwed in.
The diameter of pegs or pins 13, 14 is matched to that of blind holes 7 so that they can be inserted or driven into the latter without interruption, if possible without play or in press fit. The assembly and connection of module units placed atop and next to one another can be seen in FIG. 2. Simultaneously it can also be seen there that, atop one U-shaped module unit, another module unit can be attached as an upside-down "U," so that a considerably larger open space is produced.
Base panel 2 and carrying uprights 5 of module units 1 preferably have a uniform depth 21. Height H of carrying uprights 5 and length L of base panels 2 of module units 1 can basically be different. But they are always made of a size such that continuous construction is possible.
In particular, height H of carrying uprights 5, relative to height h in each case of one spacer collar 15, is of a size such that total heights H+h of different module units have a ratio to one another such as 1:1.5 or 1:2 or 1:3 or the like. This way, module units 1 of various heights can be placed next to one another, but they always come together after a predetermined height in a common horizontal connecting line W (see FIG. 4), so that units standing next to one another can always be rigidly connected to one another. With a height h of 1.6 cm of spacer collar 15, the height of carrying uprights 5 is, for example, 24 cm, 36.8 cm or 75.2 cm.
Consequently, various lengths L of differently configured module units 1 are selected so that length L of a base panel 2, and length A in each case of one spacer peg 20, i.e., total length L+A of different module units 1, have a ratio to one another such as 1:1.5 to 1:2. This guarantees that, when different module units 1 are placed in a row, continuous vertical carrying walls T (see FIG. 4) can be formed from carrying uprights 5 located atop one another.
Wall thickness 17 of carrying uprights 5 and of base panels 2 is preferably selected equal. It preferably is about 10 mm to 40 mm, in particular about 20 mm, or a corresponding standard measurement deviating from this.
Diameter 16 or the width of spacer collar 15 is about 70% to 110%, in particular about 90% to 100%, of wall thickness 17 of carrying uprights 5.
Height h of a spacer collar 15 corresponds about 70% to 120%, in particular about 80% to 90% to wall thickness 17 of carrying uprights 5.
Length A of spacer bars 20 is preferably of a size such that distance a achieved between two carrying uprights 5 of adjacent module units 1 is about 70% to 120%, in particular 80% to 90%, of wall thickness 5. In particular, length A is equal to or approximately equal to height h of spacer collar 15.
Connecting elements 12, 18 of foot elements 22 consist preferably of metal, in particular of aluminum.
As shown in FIG. 2, peg-shaped foot elements 22 can be provided that have a spacer collar 15 and pegs or pins 13, 14. Upper peg or pin 13 can be inserted into a blind hole 7 and lower peg or pin 14 can be inserted into a preferably cup-shaped adjusting foot 23. One or both pegs or pins 13, 14 can have an inner or outer thread into which or onto which adjusting foot 23 can be screwed. Thus an evening of height when assembling the shelf, shelf system or partition can be performed. Suitably, adjusting foot 23 can be expanded downward and outward, in particular conically. Thus a wide base 24 is obtained.
The length of pegs or pins 13, 14 of connecting elements 12 and 18 and of foot elements 22 is about 70% to 200% of wall thickness 17. Blind holes 7 are made correspondingly deep.
Distance 25 between two blind holes 7 is about 90% to 60% of depth 21 of a module unit. At least one additional blind hole 7 can be placed between two blind holes 7 arranged this way, in particular symmetrically to them.
Any high-quality, commercially available, long-lasting and as environmentally friendly as possible a material of great stability can be used as material for the module units. In particular, they consist of solid wood, veneered particle board or plywood. Base panel 2 and carrying uprights 5 are suitably joined by mortise and tenon, for example by wood or metal pins or by suitable grooving of the end faces.
A module unit 1 can also be made as cabinet unit S by hinging, on a carrying upright 5 or on both carrying uprights 5, a door leaf 26 or two door leaves 26. Such a door leaf 26 can also be attached to base panel 2.
Further, one or several module unit(s) 1 can be provided with at least one drawer 27.
Further, a carrying panel 28 can be provided that has the size of a base panel 2 and has, at points allocated to blind holes 7 of the module unit of corresponding size, continuous holes 29 with diameter equal to those of the blind holes of the module units. The thickness of carrying panels 28 corresponds preferably to wall thickness 17 of base panels 2.
Shelves, shelf systems or partitions built according to the invention are inherently stable and thus can be placed free-standing at any point in a room, in particular also be used as partitions. The individual module units can be freely interchanged, and for each such interchange no tools are needed. All connecting elements are made as insertable parts that are easy to produce and easy to use.
