Abstract

The invention relates to an expandable supporting frame (1) which can be assembled to construct a shelf, table or platform and which has storage flat elements (3, 4). The inventive supporting frame comprises at least one frame span (10) having lateral supports (2) on the outer sides thereof. At least one storage flat element (3) comprised of wire grating (3) is inserted between said lateral supports. The frame span (10) can be expanded with additional frame spans (10) by supplementing the same with additional lateral supports (2) and storage flat elements (3, 4). The lateral supports (2) are either configured in a ladder-like manner and are comprised of vertical legs (20) which are parallelly interspaced and between which rungs (21) extend, said rungs being horizontally arranged at systematic distances in a fixed manner, or individual legs (20) are used. At least one storage flat element (3) extends between two adjacent lateral supports (2) or between the pairs of legs (20). Said storage flat element is comprised of wire grating and has fixing units (60) which are arranged in a fixed manner in the outer corners thereof and by means of which the storage flat element is detachably fastened to the legs (20). When using lateral supports (2), the shelf flat elements (4) can be hung with the connecting parts thereof (40, 40') on the rungs (21). The connecting parts (40, 40') of adjacent shelf flat elements (4) push against each other and comprise sections which engage with one another. Specific decorative effects can be obtained using cover profiles, cover plates and receptacles placed on the supporting frame (1) which are made of semi-transparent material. The supporting frame (1) is characterized by its stability, easy assembly with regard to a high degree of variability, and by its effective design.

Description

Modularly expandable support frame with surface elements made of wire mesh to hold articles

Field of application of the invention

The present invention relates to a modularly expandable support frame for receiving articles. These articles can e.g. are goods that are presented in shops or at trade fairs. Such articles could also be information carriers, such as press products or brochures about the services offered. As a further example, the term item also includes items for private or professional use that must be kept in an orderly manner. The shelf elements of the supporting frames, which are designed in the form of shelves, tables and pedestals, are made of wire mesh. Storage surface elements that are less relevant for the statics of the supporting frame can also be made of plate material, e.g. made of wood or glass. The support frames can be fixed on feet or can be moved with casters. Such frames, which are at least essentially made of wire mesh, are generally characterized by solidity, load-bearing capacity, technical precision, and filigree and optical lightness due to their transparency. Depending on the accentuation in the design, these frames are therefore particularly suitable for the office or living area, as well as for the range of technical household appliances, radio and electrical goods, household and do-it-yourself goods, but also for clothing.

State of the art

A wire mesh shelf is known from GB-A-2 265 078, where differently configured goods carriers can be suspended between two vertical side supports. The side supports are preferably fixed to a rear wall or clamped between the floor and ceiling. In the side supports, in the form of a U-profile with its opening facing backwards, there is a slot grid with slots pointing obliquely downwards. The side flanks of the goods carriers can be hooked into the slots. This wire mesh shelf is very limited in its area of application because it cannot be set up free-standing because of the vertical supports to be fixed. WO-A-86/06261 discloses a further wire mesh shelf which has four rod-shaped vertical supports. Eyelets are provided on the shelves in the corner areas, which can be pushed onto the vertical supports. The distances between the shelves pushed on can be adjusted by spacing sleeves of the same length between the eyelets or by fixing the eyelets to the vertical supports. This wire mesh shelf can be positioned free-standing, but the assembly is complex, the stability should not be very great and a modular extension of the shelf with several shelf fields and trays at exactly the same height is not possible.

US-A-4,231,298 proposes a wire mesh shelf where the side supports are formed by shelf ladders. Vertical wires in pairs are arranged in zigzag on the inside of the spars, with the curved wire tips on both sides lying at the same height and pointing to the level of the shelf ladder. The trays have longitudinal bars with recesses facing each other on the inside. A shelf is hung in the area of two opposite wire tips, where their distance from each other is reduced, and the shelf is lowered so that the vertical wires bent downwards move into the recesses. Such a wire mesh shelf is probably easy to assemble, but the shelf ladders are relatively complicated, the shelf as a whole is coarser in nature and therefore only suitable for heavy objects.

The object of FR 2 217 917 is a shelf which is formed from plate-shaped, horizontally insertable trays and from pipe pieces which can be plugged together to build up the side supports. The pipe sections have a spigot and a sleeve part into which the spigot of another pipe section can be inserted. The trays are provided with a groove on the edges facing the side supports, so that strip-shaped areas of half the material thickness are created on both sides and a flipped plate can be applied overlapping there. There are vertical openings in the edges for pushing through the pins of the pipe pieces, the pin engaging in the sleeve part arranged underneath. Adjacent trays can be positioned at the same height or offset. This shelf with its plate-shaped Trays lack the transparent, optical lightness of a wire mesh construction. Furthermore, the side supports consist of numerous pipe pieces that can be plugged together, which causes a higher assembly effort and could reduce the stability.

Finally, from GB 990 751 a wire mesh shelf is known which has shelf ladders as side supports, each consisting of two vertical bars spaced parallel to each other and cross bars inserted between them. Gratings with longitudinal and cross struts form the shelves, with the outer cross struts lying in pairs above one another. A clamping piece is inserted into each of the four corners of the shelf, each of which comprises one of the first vertical bars and which lie in pairs on both cross bars of a high position. On the side of the already inserted shelf, the clamping pieces of an adjacent shelf lying at the same height encompass the second vertical rods of the shared side supports. This construction is particularly disadvantageous in that considerable gaps remain between adjacent shelves which are arranged at the same height, as a result of which no optically closed levels are created and smaller objects stored on the shelf can fall through the gaps.

Object of the invention

In view of the disadvantages shown, the invention is based on the object of proposing a modularly expandable support frame for accommodating articles, for example for presenting offers or as furniture in the office or living area, the storage surface elements of which are at least those which are relevant for statics - Are formed from wire mesh. The support frame to be created should be characterized by a solid stability - in a free-standing arrangement -, variability, simple assembly and disassembly as well as an original design that corresponds to the visual requirements in furniture and shop construction. The supporting frames must be able to be set up as stationary and movable shelves, tables and platforms. When extending the length, additional storage surface elements should be able to be added, with adjacent surface elements being as smooth as possible and on one level. The connections between the surface elements and the lateral vertical supports The support frames must be manufactured and removed quickly and without special tools.

Overview of the invention The modularly expandable support frame can be set up as a shelf, table or platform with storage surface elements. It has at least one first frame field, on the outer sides of which there are side supports, between which at least one storage area element made of a wire mesh is installed. The first frame field can be expanded with additional frame fields by supplementing it with side supports and storage space elements adjoining the first frame field. The side supports are either ladder-shaped and consist of vertical legs spaced parallel to one another and rungs extending horizontally between the legs and fixedly arranged at systematic intervals. Or the side supports are formed by individual legs. At least one storage surface element in the form of a surface mounting element made of wire mesh extends between two adjacent ladder-shaped side supports with legs or between two pairs with at least two individual legs each. Fixing units are fixedly arranged on the build-up surface element, preferably on the outer corners of the build-up surface element, by means of which it is fixedly and detachably attached to the legs. When using ladder-shaped side supports, shelf elements in the form of insert surface elements with their connection parts present on the side flanks can be suspended on a rung of two adjacent side supports. The connecting parts of adjacent insert surface elements abut one another and have interlocking sections.

The following description relates to preferred exemplary embodiments of the support frame according to the invention. In the legs, at the level where the mounting surface elements are to be attached, there are openings, preferably in the form of continuous internal threaded bores or slots, for connection to the fixing units. In the configuration as a shelf or table, between two ladder-shaped side supports at least two mounting surface elements with their fixing units, preferably to First and top of the support frame, fixed and detachable. The first version of the fixing unit consists of a half-shell which is arranged vertically in the area of an outer corner of the surface area element, the opening of which points towards the leg of the side support and which is detachably fixed to the leg by means of a connecting part, preferably a screw. The shaft of the connecting part engages in the opening, preferably an internally threaded hole, on the leg. A through hole is provided in the half-shell for the shaft to pass through. On the side of the opening, the through bore is surrounded by a radial groove in order to partially accommodate a locking ring pushed onto the shaft. Between the head of the connecting part and the half-shell, a rosette is formed on the curve of the latter.

The surface area element consists of a grid arrangement of longitudinal and transverse wires, the upper side of which forms the storage area. On the side and longitudinal flanks, the surface area element is in each case surrounded by supporting wires spaced parallel to one another and a support wire. The support and support wires from a side flank and a longitudinal flank run towards the half-shell and are fastened to it, preferably stuck in holes by welding. A wire from the longitudinal flank protrudes into the half-shell. Complementary to the protrusion, there is a through hole in the leg adjacent to the opening, into which the protrusion can be inserted when the half-shell approaches the leg.

The second version of the fixing unit consists of a partially closed housing which is fixedly arranged in the area of an outer corner of the mounting surface element, a fixing bracket firmly seated therein and a vertically movable clamping hook held by a screw. The hanging bracket has a prong pointing downwards and the clamping hook has a prong pointing upwards. Both prongs are designed to engage the slit-shaped openings in the leg. The screw head is supported on the upper cover of the housing, while the threaded shaft of the screw extends through the cover and engages in an internally threaded hole in the clamping hook. The sections which engage in one another on the insert surface elements from the end parts are formed from tongues which overlap the rung and complementary cutouts present in the respectively adjacent connection part. There is a horizontal shoulder between the tongues on each side flank, which is used for partial support on the rung and for bumping into the neighboring horizontal shoulder. A vertical stop strip extends downwards from the connection parts. Both connection parts arranged on the insert surface element on the right or left side flank represent identical components. The tongues are provided in different displacements from the nearest longitudinal flank. Viewed from the front longitudinal flank, the recesses are located in front of the tongues on the first side flank. By reversing the side of the connection part on the second side flank, the recesses are located behind the tongues.

The insert surface element can be designed so that it can be swiveled up on the axis of the front longitudinal flank between the two connection parts. A notch strip with notches open downward is then attached to the side flanks. A swiveling bracket is inserted between the connection parts and can be snapped into a pair of notches on both notch strips depending on the angle of the insert surface element. In the area of the rear longitudinal flank, another support wire will be arranged between the two connection parts for stabilization.

A U-shaped cover profile is provided for the cladding of the built-on surface element and the insert surface element on the accessible side and longitudinal flanks, which has a center leg and two side legs angled away from one another and facing each other. Near the outer edge, the side legs each have an axially extending fillet, in which two of the supporting wires or other locking elements come to rest when the cover profile is snapped on. Parallel to the fillets there is a female connector near the middle leg, behind which decorative elements and / or writing or drawing supports can be inserted. A special look can be achieved if the cover profile is made of semi-transparent material and semitransparent material is also used to cover the storage areas and for containers that can be placed on the storage areas of the supporting frame and serve to directly hold articles.

The insert surface element can also be made of plate material, e.g. Wood, glass or plastic. A connection section is again arranged on each of the two side flanks.

embodiments

The detailed description of an exemplary embodiment of the support frame according to the invention as a whole and of its components is given below with reference to the accompanying drawings. Two versions of the fixing unit by means of which the surface area elements are fastened to the vertical struts of the side supports are described. Without wishing to limit the scope of the invention, the illustration initially concentrates on supporting frames in the form of a shelf. Possible modifications worth mentioning are listed in the appendix to the description.

The following definition applies to the entire further description. If reference numerals are included in a figure for the sake of clarity in the drawing, but are not explained in the directly associated description text, reference is made to their mention in the preceding or following description of the figures. In the interest of clarity, the repeated designation of components in other figures is mostly dispensed with, provided that it can be clearly seen in the drawing that the components are "recurring". Figure 1

The support frame 1, for example in the form of a shelf, consists of at least two vertically spaced-apart side supports 2 - here shelf ladders -, mounting surface elements 3 with fixing units in the outer corners and insertion surface elements 4 with two lateral connection parts 40, 40 '. The fixing units 60 shown are those of the second version.

In the example here, three side supports 2 are set up between which two frame fields 10 are formed. You can extend the support frame 1 in any modular manner by attaching additional side supports 2 and completing it with mounting surface elements 3 and insertion surface elements 4. The overall height of the support frame 1 will be determined according to the spatial conditions, the accessibility by users, staff or the public as well as the static load-bearing capacity and the articles to be accommodated. At the bottom and at the top, a mounting surface element 3 is inserted between adjacent side supports 2, which is detachably fastened to the side supports 2 by means of fixing units 60 located on the four outer corners of the mounting surface element 3. The insert surface elements 4 with their connecting parts 40, 40 'can be placed on the rungs 21 of the side supports 2, the connecting part 40' of an insert surface element 4 engaging in the connecting part 40 of the adjoining insert surface element 4. The upper sides of each mounting surface element 3 and each insertion surface element 4 form storage surfaces 31, 41 onto which articles to be picked up can be placed directly or indirectly.

Figure 2A

A side support 2 has two mutually spaced, longitudinally extending legs 20, between which systematically horizontal rungs 21 - here seven in number - are fixedly arranged. For a more solid stand, leveling and protecting the floor, 20 plate feet 22 are provided on the legs below. If the support frame 1 is to be movable, 22 base rollers are provided instead of the plate feet. Below the bottom rung 21 and above the top rung 21 are in the Free ends of the legs 20 have openings 23, which are used to connect the fixing units 60 of the mounting surface elements 3. The shape of the openings 23 differs between the two proposed versions of the fixing units 60, 30; it can be slots or holes. The openings 23 each point to the longitudinal direction of the build-up surface elements 3. The legs 20 are preferably formed from tubes and round material is particularly suitable for the rungs 21.

Figure 2B, a surface area element 3 consists of a wire mesh with a plurality of longitudinal wires 32 and transverse wires 33 in the plane of the storage surface 31. On the side and longitudinal flanks 38,39, the surface area element 3 surrounding frame-shaped, support wires 34-36 are provided, which are parallel and are spaced one above the other. A first support wire 34 lies at the top in the plane of the storage surface 31, a second support wire 35 lies immediately below and the third support wire 36 lies at the bottom from the second, middle support wire 35. The longitudinal and transverse wires 32, 33 are located between the first and second support wires 34, 35, preferably connected to one another by welding. A support wire 37 runs between the second and the third support wire 35, 36 in a zigzag shape. The second version of the fixing units 60, into which the support wires 34-36 protrude, sit in the four outer corners of the mounting surface element 3. The support wires 34-36 are preferably also welded in the fixing units 60.

Figure 2C

The insert surface element 4 is identical to the build-up surface element 3 with regard to the storage surface 41. The longitudinal and transverse wires 42, 43 are inserted between the first and second support wires 44, 45, which enclose the insertion surface element 4 on the side and longitudinal flanks 48, 49, preferably again welded. The third support wire and the support wire are omitted here. On the side flanks 48 of the insert surface element 4 there is in each case a connection part 40, 40 'which extends over the width of the insert surface element 4. The connecting parts 40, 40 'are exactly identical parts, which are each attached to the right and left side flanks 48. The connecting part 40, 40 'has a vertical stop strip 400, 400', which has a horizontal extension 401, 401 'in the plane of the storage surface 41, which extends away from the insertion surface element 4 in its longitudinal direction.

Two downward-reaching tongues 402 403: 402 ', 403' protrude from the horizontal extension 401, 401 '. The tongues 402, 402 'and 403.403' lie diagonally opposite one another due to the arrangement on the right and left side flanks 49, with tongues 402, 402 '; 403.403' pointing outwards. A recess 404,405; 404 ', 405' is provided in the horizontal extension 401, 401 'adjacent to each tongue 402, 403', 402 ', 403' Recess 404,405; 404 ', 405' are offset from the longitudinal flanks 49. Due to the arrangement of the identical connection parts 40, 40 'on the right or left of the insertion surface element 4, the recesses 404', 405 '- viewed from the front longitudinal flank 49 behind the tongues 402 ', 403 \ the recesses 404.405, however, in front of the tongues 402.403.

Figure 2D This adjustable insertion surface element 4 differs from the non-adjustable embodiment according to the previous figure 2C by the design on the side flanks 48. The adjustable insertion surface element 4 can be swiveled up on the axis of the front longitudinal flank 49 between the two connecting parts 40, 40 '. On each of the side flanks 48 there is a notch strip 47 with notches 470 that are open at the bottom. In the area of the rear longitudinal flank 49, a third support wire 46 extends for stabilization between the two connection parts 40, 40 '. Between the connection parts 40, 40', a swivel bracket 471 is also inserted, which, depending on the angle of attack of the insertion surface element 4, is divided into a pair of Snap notches 470 into both notch strips 47. The further the notches 470 occupied by the bracket 471 face the front longitudinal flank 49, the steeper the insertion surface element 4 is set. Figures 3A to 3D

In a first version of the fixing unit 30, this first consists of a vertically extending half-shell 300, which is inserted into each outer corner of the mounting surface element 3 and whose opening 301 lies in the plane of the side flank 38. For the ends of the support wires 34-36 and the support wires 37 tapering toward the half-shell 300 from two sides, holes 302 are provided in the half-shell, into which the ends of the wires 34-36, 37 are inserted and welded. The ends of the support wires 37, which run on the longitudinal flanks 39, preferably protrude into the half-shell 300 with a projection 370. Between the second supporting wire 35 opening into the half-shell 300 and the support wire 37 there is a through-hole 303 in the half-shell 300. On the side of the opening 301, the through-hole 303 surrounds a radial groove 3030 for receiving a locking ring 304 for captively holding a plugged-in connecting part 305, preferably a screw. The shaft 3050 of the connecting part 305 is pushed through a rosette 306, which is seated on the outside of the half-shell 300 in the assembled state. The head 3051 of the connecting part 305 is supported on the rosette 306 and is for pre-assembly, i.e. For non-slip gripping with the fingers, preferably with an external knurling.

In the leg 20 of the side support 2 there is an opening 23 through the leg 20, preferably an internally threaded bore, complementary to the through hole 303 and for the engagement of the shaft 3050. A through hole 230 is provided below the opening 23 for inserting the protrusion 370 of the support wire 37. The through opening 23 and the through bore 230 emerge on both sides of the leg 20, so that mounting surface elements 3 with their fixing units 30 can be attached to a side support 2 at the same height from two sides. It is practical to dimension the protrusion 370 and the shaft 3050 of the connecting part 305 such that the mounting surface element 3 can first be hooked into the through-hole 230 with the projection 370 and then - when the load of the mounting surface element 3 is supported - by screwing in the Connecting part 305 begins. In the head 3051 of the connecting part 305 there is an engagement contour 3052 for inserting a tool.

Figures 4A and 4B With the built-in surface area elements 3, the support frame 1 receives stability. The insertion surface elements 4 serve to further subdivide the frame fields 10 in order to create additional storage surfaces 41. On each free rung 21 of a side support 2, two adjacent insertion surface elements 4 with their complementary abutting connection parts 40 ', 40 can be placed. The horizontal projections 401', 401 of two insertion surface elements 4 coming together are intended for partial resting on a rung 21. The tongues 402, 403, 402 ', 403' of the insert surface elements 4 overlap the rung 21, which comes to rest between the stop strips 400 ', 400. If two inserted insert surface elements 4 meet on a rung 21, the tongues 402, 403; 402 ', 403' of one insert surface element 4 each engage in the recesses 405 ', 404'; 405.404 of the other insert surface element 4. This interlocking enables a stable arrangement of the insert surface elements 4, which are only suspended in a simple assembly, and a closed storage surface 41 also at the transitions to the adjacent frame panel 10.

Figures 5A and 5B

A U-shaped cover profile 5 is proposed for cladding the side and longitudinal flanks 38, 39 of a mounting surface element 3, insofar as they are accessible. The cover profile 5 has the middle leg 50 and the two side legs 51 which are angled away from one another and face away from each other. Near the outer edge, the side legs 51 each have an axially extending fillet 510. Parallel to the fillets 510, a spring strip 511 is provided near the middle leg 50. The fillets 510 are used to snap onto the first and third support wires 34, 36. Decorative elements and / or writing or drawing carriers can be inserted behind the female connector 511, which come into effect when an at least semi-transparent material for the cover profile 5 is used. A particularly decorative design can be used with achieve semitransparent covers also for the storage surfaces 31, 41 and when using containers made of the same or similar material in the support frame 1.

Figure 6A to 6G

In a second version of the fixing unit 60, this is also arranged in the four outer corners of the mounting surface element 3. The supporting wires 34-36, which run from the side and the longitudinal flanks 38, 39 to the fixing unit 60, and the support wires 37 (not shown) are fastened to the fixing unit 60, e.g. shrink wrapped. The fixing unit 60 has a housing 600 which is partially encapsulated on the outside and which can be attached to a leg 21 of a side support 2 with semicircular cutouts 601. The principle here is based on a hook-shaped hanging bracket 61 and a clamping hook 62, both of which engage in openings 23, in the form of slots 23, in the leg 21 and are separated from one another by a screw 63.

The fixed plate-like hanging bracket 61 has a downward-pointing prong 610, which is intended for hanging in the first, lower slot 23 in the leg 21. The clamping hook 62 is held in the housing 600 by the screw 63 protruding through the cover 602 of the housing 600. The clamping hook 62 is equipped with an internally threaded bore 621 for engaging the screw 63, an upwardly pointing prong 620 and an upward, preferably non-circular locking lug 622. The upward-pointing prong 620 is provided for engagement in a second, upper slot 23. For the passage of the threaded shaft 630 of the screw 63, there is a bore 603 in the cover 602, the screw head 631 being supported on the top of the cover 602. Adjacent to the bore 603 there is an opening 604 in the cover 602 which is complementary to the contour of the locking lug 622.

Before attaching the mounting surface element 3 to a side support 2, the threaded shaft 630 of the screw 63 has first been screwed through the cover 602 into the internally threaded bore 621 in the clamping hook 62, so that the Clamping hook 62 is held in the housing 600. Now the prong 610 of the mounting bracket 61 is hooked into the first, lower slot 23 and the upwardly pointing prong 620 of the clamping hook 62 is inserted into the second, upper slot 23. Now the screw 63 is tightened, as a result of which the clamping hook 62 rises increasingly and finally grips behind the second upper slot 23 upwards with its prong 620. In the fixed end position of the clamping hook 62, the locking lug 622 comes to rest in the complementary opening 604 of the cover 602. This shows the correct bracing, and the clamping hook 62 is secured against lateral tilting.

Further design variations can be implemented for the devices described above. Here are also explicitly mentioned:

- On the insert surface element 4, the framing third support wires and the support wires can be provided to the insert surface element 4 on the

To give side and longitudinal flanks 48, 49 the same height as the surface area elements 3 have. This opens up the possibility of also attaching 4 cover profiles 5 of the same height to the insert surface elements.

- To cover the side and longitudinal flanks 48, 49 of the insert surface elements 4 without the third support wires and the support wires, the middle leg 50 of the cover profile 5 can be narrowed, so that the first and second support wires 44, 45 come to lie in the fillets 510.

- As an alternative to the wire mesh, an insert surface element 4 can also be made of plate material, e.g. made of wood or glass. The connecting parts 40.40 'are arranged on the side flanks 48.

- With higher loads or other design requirements, it is also conceivable to have the ladder-shaped side supports 2 with more than two spar-shaped

To equip legs 20, for example, a third leg 20 could be provided as a central spar. It would also be possible, instead of two individual legs 20, to set up further legs on the side flanks of the frame fields 10, for example three legs 20 lying in a vertical plane, which form the side supports 2. - For a support frame 1 of low construction height, a construction surface element 3 can suffice for sufficient stability, depending on the construction height and intended load. For higher and more heavily loaded support frames 1, at least two mounting surface elements 3 will be used, which are preferably mounted on the bottom and top of the side supports 2. With shelf and

Table configurations are preferably side supports 2 in the form of a ladder with horizontal rungs 21 between the legs 20. After the subdivision of the frame section 10, 41 insert surface elements 4 can be placed on the rungs 21 to create further storage surfaces. The support frames 1 configured in this way are also made by attaching further side supports 2 and mounting surface elements 3 and insert surface elements 4 if required.

- In a design of the support frame 1 without insert surface elements 4, 2 individual legs 20 can be used as side supports instead of the ladder-shaped ones
