Description

The present invention relates to a shelf furniture, which consists essentially of wound cardboard.

Methods and apparatus for the production of wound paperboard tubes with circular and also with polygonal cross-section have been known for some time. This is how the document reveals DE 1 943 097 a device for the production of wound cardboard tubes with polygonal cross-section and corresponding manufacturing methods.

Tubes made of wound cardboard can be inexpensively manufactured by the meter, the production length, depending on the width of the reel spool, can be several meters. The winding is characterized in that the individual cardboard layers during their production, d. H. during winding, are glued together. The resulting laminate-like construction gives the tubes a high strength. Tubes with a smaller diameter, the z. As the inclusion of tape, are also referred to as cardboard tubes or paperboard.

The tubular material can be provided in various diameters and is characterized by a high stability, in particular by a high flexural strength. If the tubular material has a polygonal cross-section, the side surfaces may have an inward or outward curvature, i. H. the side edges forming the cross-section of the tube element in this case have no rectilinear but slightly curved course.

The use of wound paperboard tubes with a circular cross-section and a small diameter as stabilizing elements in the production of furniture components, in particular also for the production of shelf components, is also known. This is how the documents reveal WO 01/30201 A1 and EP 2 123 192 A1 each components for building multi-part furniture, wherein the stability of the components is improved in that a plurality of wound cardboard tubes is arranged with a circular cross section in the interior of the components.

The document DE 198 39 414 A1 discloses a shelf made of cardboard, which consists of shelves, shelves and support bars. The support rods may be formed as wound hollow profiles made of paper or cardboard. The shelves have in their lateral edge portions slots for the vertically arranged shelf cheeks. The shelf members in turn have pairwise arranged at different heights through openings, which serve for the insertion of support rods for holding the shelves. The modular shelving system allows a free design of the shelves and the base geometry. The shelves which can be assembled in this way are floor shelves, with the downwardly directed end faces of the shelf cheeks each serving as a base. The individual shelf components are, according to their complex construction, consuming even in the production.

The known from the prior art shelves made of cardboard are multi-part, even if the shelf has only one shelf, d. H. they correspond in their construction to the conventional construction of a shelf or a cabinet wall, each consisting of lateral, vertically arranged shelf cheeks, and shelves, which extend horizontally and are arranged between the shelf cheeks. The preparation and in particular the joining of the items is costly and time consuming in the known cardboard shelves.

Against this background, the object of the invention is to provide a shelf which is essentially constructed of wound cardboard, is characterized by high stability, is inexpensive to manufacture and can be set up quickly.

The object is achieved by a shelf furniture according to claim 1.

The essence of the invention is the use of portions of a tubular material which is industrially and thus inexpensive to produce, wherein the interior of the tubular portion (tubular member) each forms a shelf. Particularly suitable for building a shelf furniture are tubular elements made of wound cardboard whose interior, d. H. the enclosed by the tubular material area, each forms a separate shelf. In order to stabilize the tubular elements and / or to correct the curvature of the side surfaces explained above in the case of a tubular element with a polygonal cross section, it is provided that the tubular elements are connected to a carrier plate arranged in the region of the rear side of the shelf. Alternatively or additionally, the tube elements can be connected to one or more frame elements lying in sections on the lateral surface of the tube element, which are arranged both in the region of the front of the shelf and in the region of the rear of the shelf. The frame members have openings whose size and shape corresponds to the outer cross section of the tube elements. The support plate and / or the frame elements connect, d. H. bundle the tube elements in this way and at the same time stabilize them.

Alternatively or additionally, tube elements arranged parallel to one another can also be connected to one another by gluing or by means of screws, rivets or another type known to the person skilled in the art. The stability of a built-up of several tubular elements shelf furniture results from the high bending strength of the individual tube elements and from the connection of the tubes with each other.

The sections designated as tubular elements in the context of the present invention and made of wound cardboard are distinguished by a comparatively large diameter of up to 600 mm and at the same time by a high bending strength in the longitudinal direction of the tube.

Alternatively or in combination with tubular elements made of wound cardboard tube elements made of a different material, in particular of a plastic, can be used. Plastic pipes with a circular or polygonal cross-section can also be produced industrially in various diameters and lengths.

The shelf furniture according to the invention (shelf) in its most general form is constructed from a tubular element, or from a plurality of tubular elements, each having a circular or polygonal cross-section, wherein the tubular element, or in a built of more than one tubular element shelf furniture, at least a part of Tubular elements, is arranged so that the interior of these tube elements in each case from a lateral direction, or from above, accessible shelf compartment forms.

The tubular elements with polygonal cross section may have rounded corners, wherein the rounding of the corners already takes place during the manufacture of the tube elements.

For tubular elements made of wound cardboard, a distinction must be made between parallel winding and spiral winding. Tubular elements made of parallel wound cardboard are characterized by high rigidity compared to spirally wound tubes. Therefore, parallelepiped tube elements are preferably used for the shelf furniture. With appropriate wall thickness and shorter lengths, d. H. at low shelf depth, spiral-wound tube elements can also be used.

In the case of tubular plastic elements, the choice of the type of plastic can determine the strength and stability required for the respective length of the tubular element. The usable as tubular elements for the shelf furniture plastic materials are known in the art.

The access to the respective shelf can be made via the open side areas of the tube element or from above. A shelf according to the invention can serve as an object of the interior decoration in the living area (furniture) or as a sales aid for the advantageous display of goods.

The shelf-forming tubular members may be arranged so that their longitudinal axis is respectively aligned in the horizontal direction, or in the vertical direction, or in any direction lying between the vertical and the horizontal orientation. It is preferred if all tube elements are arranged so that their longitudinal axis is aligned in the horizontal direction.

However, the orientation of the tube elements, i. H. the orientation of the longitudinal axes of the tube elements, with respect to the footprint of the shelf in other, alternative, embodiments not set to the horizontal direction. Also for design reasons alone or for reasons of statics, d. H. for additional stabilization of the shelf furniture is conceivable that individual tubular elements are arranged in the shelf furniture so that its longitudinal axis extends in the vertical direction or in any direction lying between the horizontal and vertical orientation (oblique position) is aligned. It is conceivable that the sole or predominantly the stabilization of the shelf furniture serving tube elements do not form a shelf.

It is envisaged that, in the case of a shelf unit consisting of several tube elements, the tube elements can be arranged next to or above one another. It is also envisaged that the tube elements can be arranged both side by side and one above the other so that the shelf as a whole has a cubic spatial form. At least the tube elements lying in one plane each have the same diameter. Such an arrangement is very well suited as a room divider with shelf function. With decreasing diameter of the tube elements, such a shelf furniture can additionally or primarily serve as a room plate with soundproofing function.

In thick-walled tubular elements mounting positions are provided, these mounting positions in the tubular element, for. B. in the form of openings in the wall-side end portion of the tubular element, are embedded. Due to the mounting positions, the respective tube element (as in 1a shown) directly to the wall.

In a preferred embodiment it is provided that the tubular element of a shelf unit having only a shelf, or the Tubular elements of a shelf unit with a plurality of shelves, in the region facing away from the front side, ie on the back of the shelf, are positively connected to a vertically oriented support plate or a support frame. The support frame has an opening which surrounds the tube elements on the outside.

Support plate and support frame can be used in a rack furniture in combination with each other. Thus, it is conceivable that on the shelf back a support plate, in the region of the shelf front side a support frame and for additional stabilization of the tube elements in the center of the shelf unit another support frame is arranged.

The use of a carrier plate forms a back wall for the shelves and at the same time facilitates the installation of the shelf on a building wall.

In the fourth alternative iv.), the support plate has a groove-like groove, wherein the groove / groove in shape and size corresponds exactly to the wall forming cross-section of the tubular member, so that the rear end portion of the tubular member can be received by the groove , The depth of the groove is variable, wherein the stability of the connection between the support plate and tube member with increasing depth of the groove becomes larger, since the contact area between the support plate and tube member increases. (In 1b the alternative iv.) is illustrated by the different views summarized in the fourth column.)

Carrier plate and carrier frame can be made of different materials. Preferred materials for support plate and support frame are metal, wood, plastic, composites consisting of wood and plastic parts or a thick-walled (multi-ply) cardboard. Particularly preferred as a material for support plate and support frame is wood.

The production of a positive and non-positive connection between the tube element and the carrier plate on said contact surfaces can be done in a variety of ways known in the art. Suitable as a mounting material z. As screws, locking pins, nails, rivets, and brackets. Alternatively or in combination with the aforementioned mechanical fasteners and adhesives can be used. The attachment of corresponding openings in the tube elements for receiving, or implementation, the fastening means, for. B. of screws and locking pins, can already be done as part of the manufacture of the shelf furniture or instructions for self-assembly.

The mechanical fasteners connect the tube member preferably at its upper side with the carrier plate, because act on the contact points of the top of the largest leverage. This also applies to the alternative iv.), With the use of adhesives to provide a stable connection between the surface of the groove and the tubular element in alternative iv) is particularly important because the adhesive optimally fills the groove and both the outside as also in contact with the inside of the tube element.

When assembling the shelf unit, ie in the assembly of tubular elements and support plate, or support frame, can be used as an assembly aid a funnel, ie, a widening in its scope object. The mounting funnel widens in scope to the size of the circumference of the respective increase of the support plate, or the size and size of the opening of the support frame, or the size and size of the provided in a support plate for receiving the end portion of the tubular element groove.

As an alternative to the horizontal arrangement of the tube elements is also provided that the tube elements are arranged so that the longitudinal axis of the tube member and the surface of a vertically oriented support plate, with which the tube elements are connected, include an angle of less than 90 ° and greater than 10 ° is. In this arrangement, the opening of the shelf still remains accessible from the side.

While an angle of 85 ° causes a nearly horizontal orientation of the shelf, results in a rather steep orientation of the shelf at an angle of 15 °. The increase in the shelf opening advantageously allows the introduction of bulk material in the shelves, the access of the shelf in this case (as in 4 shown) from the side-up.

In the aforementioned embodiment, the carrier plate forms the rear wall of the shelf unit, wherein the carrier plate limits the tube elements on the side opposite to the shelf opening at the same time. The support plate may have fasteners or additional openings for fasteners such as screws, which serve to attach the shelf furniture to a building wall.

In a built-up with a plurality of tubular elements shelf with support frame is a coherent, d. H. one-piece carrier frame selected, which has a corresponding number of openings for receiving the tubular elements. The openings correspond in shape and size to the outer cross section of the tube elements.

In a very particularly preferred embodiment of the shelf unit, at least part of the tube elements arranged side by side and / or one above the other has a separating element in the interior, so that the respective tube element is subdivided into two shelf compartments. The outline of the separating element corresponds in shape and size to the inner cross section of the respective tubular element. The shelves resulting from the subdivision are accessible from the opposite ends of the respective tubular element. The outline of the partition, d. H. the shape of which corresponds to the inner cross section of the respective tubular element. The introduction of separating elements in the individual shelves is particularly useful in a space provided as a shelf furniture.

In a further particularly preferred embodiment, the tubular elements are divided in a built-up of a plurality of tubular elements shelf furniture by a contiguous separating element, which is arranged perpendicular to the longitudinal direction of the tube elements. Ie. the mutually parallel and lying in one or more levels tube elements are divided by a contiguous partition, so that each tube element is divided into two shelves, the two shelves are accessible from the opposite ends of the respective tube member ago. The separating element is preferably arranged centrally with respect to the longitudinal axis of the tube elements. This embodiment of the shelf furniture is particularly suitable as a room divider (see 2a upper picture).

In a most preferred embodiment, one or more of the tube elements at the lying on the front of the shelf furniture end portion or lying on the shelf front and the shelf rear end portions from a side view obliquely extending end portion (Lyons section). Ie. with respect to the longitudinal axis of the tube member, the cut is oblique, the bottom of the tube member is longer than the longitudinal axis coincident average length of the tube member and the top of the tube member is shorter than the average length of the tube member. The extent of the slope is variable in a certain range, wherein the end face of the respective tube element with respect to its longitudinal axis has an angle which is smaller than 90 ° and greater than 10 °.

The oblique cut improves the suitability of the shelf furniture as a sales shelf, because the lying in the front of the shelf subjects are exposed and thus better recognizable.

In a preferred embodiment, the shelf furniture is constructed of a plurality of arranged in superimposed planes tube elements, wherein arranged in the same plane tube elements each have the same length, and lying in each next higher level tube elements to build a shelf cabinet with cubic shape same length, or for the construction of a shelf furniture, the decreasing depth of the shelves in the page after tapered at the top, have a different length.

In the case of the second alternative, if the tubular elements arranged in several planes are in the form of two converging stairs (see FIG 3 ) are arranged, the shelf furniture receives a total of a pyramidal shape.

Particularly preferred are shelf furniture with tubular elements whose cross section is tetragonal, hexagonal or octagonal. The tube elements may, due to production, have rounded corners. Most preferred are tubular members having a tetragonal cross section and rounded corner portions made with a LWA Q. type machine and a cross-sectional size (diameter measured in the diagonal direction) of 350 mm to 800 mm.

Most preferred is the tetragonal cross-sectional shape. Therefore, in a most preferred embodiment, the shelf furniture from a tube element, or from a plurality of tube elements, each with a tetragonal cross-section constructed and is optionally connected for additional stabilization with a support plate and / or a support frame.

The particularly preferred tetragonal cross-section is advantageous for reasons of space alone, because there are no gaps between the tubular elements in this cross-sectional shape. At the same time serving as a display surface underlying inside of the shelf is greater than a hexagonal surface. Also with hexagonal or even octagonal cross-section. Even with a hexagonal cross-sectional shape of the tube elements, a parallel arrangement of the tube elements without spaces is possible, however, the underlying as a display surface inside a shelf with a hexagonal cross-section is smaller. Even smaller is the display area in shelves with octagonal cross-section, between the adjacent tube elements square spaces created. With regard to the use of space, tubular elements with an octagonal cross section are therefore less advantageous. Visually, however, the alternating arrangement of octagonal and quadrangular openings on the front of the bookcase resulting from the use of tubular elements with octagonal cross-section can be very attractive.

To increase the functionality and in addition to the optical design of the shelf furniture is provided that one or more of the tube elements in the region of lying on the front of the shelf tube portion has a door.

For reasons of aesthetics and to protect the tubular elements is provided that they are provided on the outside and / or inside with a coating, wherein the coating of a paint, a plastic or a powder-applied material (powder coating) consists.
