Definitions

  • the present invention relates generally to a screen wall system comprising at least two wall elements and a linking device for linking the wall elements together by connection to an edge portion of each wall element. It also relates to a wall element, a floor support device and a linking device for use as respective corresponding screen wall system parts.
  • exhibition premises use screen walls for shielding and defining exhibitor areas.
  • exhibition premises are spacious with support for a great number of exhibitors and there is a need for an even greater amount of screen wall elements for building the screen walls.
  • the screen walls have to be rearranged and screen wall sections disassembled into the screen wall elements, which then, often at new locations in the premises, are reassembled into new screen wall sections for the new exhibitors. Owing to this it is desirable to be able to swiftly, and in a flexible, time and cost efficient manner, switch from one screen wall configuration to another.
  • a screen wall for exhibition premises should be simple to adjust under difficult floor conditions since floors in exhibition premises often can be rough, uneven, sloped and non-uniform, in contrast to e.g. conventional office floors. Due to this a wall element sometimes needs to be supported at floor positions of different heights.
  • the screen walls must be able to handle and adapt to such situations, not only in order to accomplish a steady support from the floor when the walls are placed in an upright position, but also in order to present smooth transitions between individual wall elements, without sudden vertical displacements between adjacent wall elements. Such displacements, especially along an upper edge of a screen wall, is eye-catching and gives a shoddy impression.
  • a predominating type of a screen wall element used in exhibition premises comprises a wooden frame with wood boards nailed to the frame so that each board forms a principal surface of the wall element.
  • This simple construction allows for repairs and modifications by simple means, such as a hammer and nails. A broken, or damaged part of the frame or the boards can easily be replaced, and the material and means used are relatively cheap. After a person has learned how to nail these wall elements together, the simple means and brute method for assembly/disassembly allow for great flexibility and adjustability, and wall elements can be connected quite rapidly. Hence, this type of screen walls meet many of the desirable properties.
  • each wall element of this kind is relatively heavy, which makes it cumbersome to move and position the wall elements. It can be noted that the weight may give rise to an additional problem in the near future since it, at least within the EU, are plans to stipulate by legislation that a single worker is allowed to carry or move objects of about 15 kg at maximum.
  • connection by hammer and nails is destructive, give rise to waste, requires frequent repairs of the wall elements and involves consumption of material, such as nails and material for the repairs.
  • a specific object is to provide a screen wall system that conveniently can be adapted to and be used on uneven floor surfaces.
  • a screen wall system comprising two wall elements and a linking device for linking the wall elements together by connection to an edge portion of each wall element. At least one of the wall elements, when connected to the linking device, is tiltable in its principal plane relative to the linking device.
  • the wall element when placed on a floor the wall element can be tilted in its principal plane in relation to the linking device so as to adapt to an uneven. e.g. sloped, floor surface, whereby the distance between the lower edge of the wall element and the floor can be kept small.
  • all linking devices can be placed vertically while the wall elements placed over a sloped surface can be tilted in-plane to adapt to the floor level change. Sudden vertical displacements of consecutive wall elements can be avoided and there is no need forwall element supports that must be able to compensate for the entire floor level variation.
  • the linking device may have an edge portion extending in a first direction, which edge portion, when the wall element is connected to the linking device, may be interlocked in a second direction with an edge portion of the wall element, said second direction being substantially parallel to the principal plane of the wall element and substantially perpendicular to the first direction, wherein the interlock may involve a play and the wall element tiltable within the play.
  • interlock involves a play
  • interlock admits some relative movement of the parts being interlocked in the interlock direction.
  • tilttable within a play is meant that the wall element can be tilted in relation to the locking device in such way that portions of the wall element that move when the wall element is tilted are movable between two lock positions that are spaced apart by the play.
  • Connection by interlocking with a play has the advantage that it allow for a tiltable wall element using a comparatively simple and robust connection mechanism, where the parts can be connected and the wall element be tiltable without the need of additional parts.
  • the wall element may further be displaceable within the play.
  • the play can be at least 0.3 cm, 0.5 cm, 0.7 cm, 1 cm, 3 cm or 5 cm.
  • the edge portion of the wall element may be provided with a wall locking element and the edge portion of the linking device may be provided with a link locking element, wherein the wall locking element and the link locking element may present lock surfaces facing each other in the second direction such that any tilt and/or displacement of the wall element away from the linking device in the second direction results in that the surfaces engage with each other at a first relative lock position.
  • the locking elements may be resilient relative to each other in a third direction which is substantially perpendicular to the principal plane of the wall element.
  • the interlock in combination with the resilient elements enable snap connection of the linking device and the wall element.
  • the linking device and the wall element may be moved together in the second direction until the wall locking element pass the first relative position whereby the locking elements and respective lock surfaces "snap" into place and accomplish the interlock.
  • the snap connection allows for easy connection of parts and assembly of a wall section. Starting from an upright positioned wall element or linking device, further parts can be added and connected so as to assemble, or disassemble, a wall section, without the need of moving or lifting large and potentially heavy structures.
  • the linking device edge portion may extend over opposite principal surfaces of the wall element when the wall element and the linking device are connected. This way a tilted wall element edge portion and/or any space between the edges of the wall element and the linking device can be hidden and the wall section present a more uniform surface.
  • the linking device may comprise two interconnectable link parts, each for the connection to one wall element.
  • the link parts when interconnected, may be parallel and turnable in relation to each other about a parallel axis.
  • each link part When connected to the respective wall element each link part may extend between opposite edges of the wall element, wherein the link parts may be interconnectable by means of a link member that is connectable to adjacent end portions of the link parts.
  • Interconnecting the link parts at an upper and/or lower end as e.g. is the case when one link part is connected to a upright positioned wall element, allow for a stable yet simple interconnection and facilitate for addition of one part at a time to an already upright positioned wall section.
  • Access for connection of the link member to a lower end facing the floor can be accomplished by tilting the wall element in relation to a distal linking device already connected to the wall element.
  • the system may further comprise a wall element locking means which, when the wall element is connected to the linking device, restricts movement of the wall element in the first direction.
  • the wall element and the linking device Restriction of movement in the first direction. i.e. the vertical direction when the wall section is in upright position on a floor, allows the wall element and the linking device to maintain the same relative vertical position during use, irrespective if the wall element is tilted or not.
  • the locking means By fixing the locking means to only one of the wall element and locking device, preferably one having floor support, the other part can be suspended using the locking means and may thus not require its own floor support.
  • the wall element locking means may comprise an elongated member and a recess which cooperates to restrict the movement, wherein the recess preferably is part of either the wall element or the linking device, and the elongated member preferably is a separate part or integrated with the part not comprising the recess.
  • a locking means of this kind is i.a. simple and robust and allows for cost efficient manufacturing.
  • the elongated member may extend between opposing edge surfaces of the linking device and the wall element.
  • the elongated member before engaging with the recess can serve as a guide member, slidable over an edge surface, and when the elongated member finds and engages with the recess a correct alignment has been provided.
  • the linking device and the wall element are snap connectable, the length of the elongated member and the depth of the recess may be selected in relation to the play of the interlock so that snap connection and interlock only is enabled when the elongated member finds and engages with the recess.
  • the system may further comprise a floor support device being attachable to an edge portion of the wall element and/or the linking device, wherein said floor support device, when attached to the edge portion, may extend from a wall end to a distal end in a direction that is substantially perpendicular to the principal plane of the wall element.
  • the floor support device prevent the wall section to tip and thus enable the wall section to be remain in upright position on a floor Using an attachable floor support means that a floor support can be used and attached only when need arises, and thus, the total number of support devices in the system can be kept low.
  • the distal end may be adjustable in a direction that is perpendicular to the edge surface of the edge portion.
  • the tiltable wall element compensates for longitudinal floor level variations, i.e. in directions along the wall elements, it suffice that the support device as here focus on compensating for traverse variations in order to be supportive for upright positioned linking devices and avoid that the wall section tip over.
  • the distal end may be adjustable by means of a wedge that is insertable between the edge portion of the wall element, and/or the edge portion of the linking device, and the wall end of the support device.
  • the wedge may comprise lock elements that engage with interrelated lock elements on the wall end of the support device and/or the edge portion of the wall element, and/or the edge portion of the linking device, in such way that the removal of the wedge in the opposite direction of insertion is restricted.
  • a wall element adapted for use as the respective corresponding wall element, floor support device and linking device in the system.
  • a link part adapted for use as the link part in the linking device.

When a specific direction along e.g. the x-axis is meant, this will be explicitly indicated.
  • Fig. 1b only the upper end of the linking device is shown, however, the linking device is in the present embodiment symmetric in the z-direction, and thus the opposite end, i.e. here the lower end, looks similar to the shown end.

Preferably the wall locking member is of the same material as the link part.
  • the wall locking element 12 may remain attached to the wall element 10 during assembly/disassembly of the wall section and hence the link locking member may but do not generally have to be removably connected to the wall element, at least not in a way that facilitate assembly/disassembly.

  • the distance ⁇ x represent a play in the interlock.
  • the link part 20 and the wall element 10 are interlocked also in the traverse y-direction, but without any significant play, which in this case may give rise to noise if e.g. vibrations causes an upright wall element to move back and forth within the play and/or may cause an undesired tilt of the wall element in the y-direction.
  • the interlock in the y-direction may thus advantageously be tight.
  • the wall element(or the link part) may be slided in the z-direction into the interlocked position.
  • this may require that a link part, or even a wall element to which the link part is already connected, may need to be lifted above an upper edge of the wall section.
  • One remedy to this may be to connect the link parts 20 to the wall elements 10 in a non-upright position, e.g. when the wall elements 20 are placed flat on the floor or a table.

  • the tilt within the interlock is possible without deformation of any of the involved parts, and that before engagement between the lock surfaces, the parts being involved in the interlock may be tilted just as easy independent on the degree of tilt.
  • the lock pin 23 and the interrelated recess may prevent or at least restrict displacement of the interlocked parts.
  • the recess being cooperative with the lock pin 23 is preferably made with a substantially larger diameter than the lock pin 23, which allow the lock pin to be tilted and still be positioned in the recess. Hence, the interlocked parts can be tilted in relation to each other notwithstanding the presence of the lock pin 23.
  • Fig. 3 shows, in side view, the link part 20 connected to a tilted wall element 10.
  • the height h of a wall element typically corresponds to the height of a conventional wall and is typically in the range 2-3 m, preferably about 2.40 m, or of any other "standard" wall height. Of course, in special circumstances, the height may also be outside the mentioned range.
  • the length 1 is typically in the range 0.5-4 m, preferably 1-2 m, e.g. 1.5 m, which results in a wall element that can be convenient to handle in practise and that may facilitate assembly/disassembly of wall sections. However, of course also other lengths 1 may be used.
  • the width (not shown in Fig. 3 ), or thickness, of the wall element is typically in the range 1-20 cm, preferably 2-4 cm.
  • a thicker wall element may be e.g. be used for larger area wall elements to increase rigidity, or simply to increase the capability of sound absorption.
  • FIG. 3 A situation with maximal tilt allowed within the interlock is shown in Fig. 3 .
  • the wall element 10 is tiled at an angle ⁇ in relation to the link part 20.
  • the maximal tilt corresponds to a ⁇ h change in level at a distal edge of the wall element 10.
  • the maximal compensation ⁇ h in height h that can be accomplished is equal to the play ⁇ x.
  • the play should at least be about 0.3 cm, but preferably at least about 0.5 cm.
  • a larger play, for example at least 0.7 cm, 1 cm or even more, is of course better in the sense that it allows for a larger degree of tilt, but there may be other reasons, e.g. design reasons, that still makes it desirable to use a smaller play.
  • the play may also be defined in relation to the height or length of the wall element. With respect to the above relationships, the play may thus be defined as at least 0.5 % or 1 % of the length or height of the wall element.
  • Fig. 4a-4c illustrates, in traverse cross-sections, further alternatives of link parts interlocked with wall elements.
  • Fig. 4a it is shown an alternative where the wall locking element 12 have two protrusions, or ridges, and the link part has only one protrusion which during interlock is positioned between the two protrusions of the wall locking element 12.
  • a link locking element may comprise or constitute a ridge or a groove in the wall element per se.
  • the ridge is constituted by a hardened strip of glue bonding to and extending along the edge portion.
  • Fig. 5a shows, in side-view, a wall section having a tilted wall element in a situation where it adjusts to an uneven, sloped floor surface.
  • a middle wall element 10 pass over the sloped part and adapt to this situation accordingly by tilting in relation to the linking devices on each side.
  • the outer wall elements are not tilted, neither are any of the linking devices, which are all parallel and vertically positioned. It can be noted that the upper and lower ends of all link parts are aligned with upper and lower ends of the linking parts they are connected to. Owing to the tilted wall element the wall section is able to present a smooth discrete transition from the higher to the lower floor level.
  • Fig. 5b shows a top view of the wall section of Fig. 5a , where the wall elements have been turned in relation to each other about a vertical axis.
  • the linking devices are hinged components, which result from that the link parts 20 of a linking device are turnable in relation to each other when interconnected using a link member 30.
  • a support device comprising a single support member attached to a linking device between two wall elements, which device only comprises one support member.
  • a support device may be attached where appropriate. Note that one or more of the wall elements may tilt in-plane even in an upright, vertically positioned wall section, i.e. where all linking devices and wall elements are vertically positioned.
  • Fig. 6a-6c illustrates, in full and partial perspective views, how a wall section having crossed wall elements can be provided, and is one example of the versatility of the system.
  • a groove 34 of a link member 30 is here used for attaching further wall elements 10 to a wall section so as to accomplish a crossing of wall elements. Since a crossing is stable per se, there is of less interest to attach a support device via the link member at the crossing.
  • a sheet shaped add-on link member 50 having a ridge that fit into the groove 34 is provided.
  • the add-on link member 50 is further furnished with a through hole 54, which when the add-on member is attached to the link member, can be placed concentrically with an upper end recesses 21 (not shown in Fig.
  • a separate connector 60 which is similar to a link member connector 32, is inserted in the concentrically arranged hole and recess so as to connect the additional wall element to the existing wall section.
  • a similar additional wall element may be connected to the opposite side of the original wall section, which is illustrated in Fig. 6 .
  • Fig. 7a-7c illustrates, in full and partial perspective views, how a wall section can be assembled.
  • the illustrated way of assembly can advantageously be employed at an initial assembly stage when there is yet no wall section part that is upright positioned and to which further parts can be connected.
