Description

Movable Wall Framework

Field of the Invention

This invention relates to movable walls, and in particular a framework apparatus for a movable wall structure.

Background of the Invention

Movable walls are commonly used in offices, industrial premises and homes and act as a partition between two open spaces. For example, an office conference room may be divided into two smaller rooms by means of a movable wall, which can be opened as required to create a larger space.

The walls may comprise several connected movable panels which can fold or which can be removed.

Existing movable walls typically comprise a rectangular framework formed of welded members within which are located one or more components which serve a variety of purposes. For example, a trolley mechanism may be welded to the top edge to enable the wall to be suspended by a trolley mechanism from a ceiling rail; a guide component may be welded to the base of the wall to locate in a floor guiding strip; an edge seal may be provided to make a sealing engagement with an adjacent wall or the ceiling.

Regarding the latter, it is desirable for movable walls to offer some degree of soundproofing when in the closed position. As such, acoustic seals are usually provided at one or more edges for engagement with the seal of another wall.

Movable walls are bespoke components designed and manufactured to suit a client's requirements. The framework is formed by welding at the manufacturer's location. Panels which form the wall cover within the framework are also usually attached at the manufacturer's location. The walls then have to be transported to the client's location for installation. This can result in damage to the wall. Further, the described components for the trolley and sealing mechanism, for example, are also welded, riveted or otherwise fixed to the framework at a particular position according to a design brief.

Repairing damaged walls or altering the position of components is a labour intensive task usually having to be done at the manufacturer's location. Further, due to the mechanical complexity of certain components and/or the way they are secured to the framework, such components typically extend within the body of the framework reducing the space available for acoustic insulation material in the body of the door.

Detailed Description of a Preferred Embodiment

Embodiments herein provide a modular system for creating a framework assembly to be used as part of a movable wall, typically one used for partitioning room spaces although other applications are envisaged. Any type of movable wall may be provided by the system, including those with wood, plaster or glass panel coverings.

Each part of the framework is designed so as to be transportable in kit form and assembled on-site without the need for welding, thus reducing transportation and assembly complexity and the likelihood of damage.

Referring to Figure 1, a first embodiment comprises a kit of parts 1 comprised of four elongate frame members 3, and four corner cleats 9. The frame members 3 can be formed of extruded aluminium, for example.

Figure 2 shows the frame members 3 when connected to form a framework to which wood, plasterboard or glass panels can be fitted. The corner cleats 9 oonnect the corners together in a known way using a friction or interference -fit arrangement and assembly of the framework can be performed on-site without the need for welding.

An exterior end face of one of the frame members 3 is shown (from view A-A) in Figure 1. As will be seen, the extrusion has an elongate channel 5 or groove which is open on the exterior side. Reference numeral 7 indicates fixing holes that may be used although this is not essential.

Just one or up to four of the frame members 3 may have such a charnel 5 extending inwards from their outer side. The purpose is to enable one or more wall components to be inserted within the channel 5 (e.g. by sliding in from one end) and which can be fixed in position within the channel by adjustable means, e.g. grub screws. Flanges may also be formed on opposed walls of the channel interior to enable one or more components to be clipped within the channel 5, either within opposed pairs of flanges, or underneath. The position of the component can be anywhere between near the end parts of the channel 5. such components can therefore be mounted at the end user's location without the need for permanent fixing, e.g. by welding or riveting. The end user can effect adjustment without having to return the assembly to the manufacturer's factory or warehouse.

The channel or channels 5 are closed off by a base wall on or towards the interior side of frame member 3, so that no components need extend within the interior space 4 perhaps with the exception of low-prcfile washers and nuts if the fixing holes 7 are to be used. This permits better soundproofing (where such material fills this void region) because there are no complicated mechanisms extending within the space. All components are preferably fitted within the exterior channel or slot(s)5.

In a second embodiment, frame members are provided so as to be connected together without the need for corner cleats.

Rather, the ends of certain frame members are shaped so as to receive the ends of other frame members so that they interconnect at or near their corners in a mortise and tenon -type joint, again without the need for a permanent welding fixture.

Figures 3(a) and 3(b) show one such frame member 10 in top plan and cross-sectional view (through section B-B) respectively. Again, the frame member 10 is preferably formed using extruded aluminium but alternative materials and forming methods may be applied. The frame member 10 has a base wall 11, and two upstanding side walls 13 defining a substantially U-shaped channel 15 for receiving components. On the interior of both side walls 13, just over half-way up, are provided a pair of hook-shaped flanges 17 extending the length of the frame member 10 which can be used for retaining components between the flanges or, alternatively, in the channel region beneath the flanges. At the top of the side walls 13 the channel opens outwards with opposed sloping wall sections 19 which extend towards wing sections 20 which lie generally parallel with the base wall 11.

On uhe lower surface of each wing section 20 is a mounting flange or rib 23 which extends downwards, generally perpendicular to the wing section 20 and base wall 11. The mounting flanges 23 extend the length of the frame member 10.

At each end of the frame member 10 is formed a stepped recess 21 for receiving, using a friction or interference fit, another frame member of similar or identical cross-section.

Thus, each recess 21 is shaped so as to accommodate the cross-sectional profile of the other frame member which is fitted perpendicular to that shown in the Figure. The recess 21 comprises a first section 21a which has approximately the same width (Y axis) as that of the base wall 11 and depth (X axis) as that of the side walls 13, and a second section 21b which has approximately the same width as the distance between the mounting flanges 23 and the same depth as that of said flanges.

Figure 4 shows the same frame member 10 with second and third (side) frame members 30, 40 fitted to the recess 21 at the ends using the friction or interference fit. It will be seen that there is a tight fit between the different members at their junction, with the mounting flanges 23 (which may be formed so as to extend slightly outwards from the vertical) gripping the interior walls of the second recess section 2lb to keep the members secured. The complete framework, represented in Figure 4, will include another frame member 50 identical to the first frame member 10 connecting the side members 30, 40 at their opposite ends in much the same way.

The side frame members 30, 40 are uniform and the end recesses 21 required in the upper and lower frame members 10, 50 are not reguired here.

Thus, in this embodiment, the framework, when assembled, comprises an exterior channel in each of the fcur frame members 10, 30, 40, 50.

In addition tc providing strength (and in the case of the side members 30, 40, the friction fit) the mounting flanges 23 are employed for the mounting of a panel to cover the interior void cf the framework. Figures 6 and 7 show alternative methods for connecting such a panel.

Referring to Figure 6, a corner recess 61 is cut within each board 53 so that The board can locate over the mcunting flange 23 as shown. Referring to Figure 7, an alternative is to cut a groove 63 along the edge of the boards 57, 59 which securely locate over the mounting flange 23. Such cuts can be made on all four sides of both boards and the frame members assembled around the board. The void 65 between the two panels 53, 55, 57, 59 can be filled beforehand with insulating material if desired.

In the case of both embodiments, the exterior channel or channels 5, 15 provide a convenient means of mounting separate components (to be introduced below) and/or enabling adjustment without the need for permanent fixing.

Typically, suoh components will be one or more of trolley components, sealing components and/or seal driver components.

Referring to the second embodiment shown in Figures 4 and 5, the frame member 10 at the top of the frame may reguire a trolley member inserted within the channel 15 to hang the frame (or door, when assembled) from a ceiling track (not shown) . The trolley can be positioned at any point between near the ends of the channel 15 and fixed in place using grub screws. A fixing part of the orolley will locate beneath the flanges 17 to limit vertical movement and the screws will either pass through the holes 7 or grip onto the channel's interior surface to prevent longitudinal or lateral movement.

The or each channel 15 of the frame members may receive components such as, in addition to trolley hangers, edge seals, top and bottom seals, and seal drive actuators; seal drive actuators are located beneath the plastics or rubber seals which extend along a channel's length. The seal drive actuators are effective to move the seals outwardly so that they effect a sealing contact with another surface, e.g. the seal on another wall or ceiling.

The primary purpose of a seal is to provide soundproofing.

For example, a room partition may be made up of two or more movable walls which separate when the room is in the open configuration and which slide back together along a track to the closed configuration whereby the room is partitioned.

The vertical side edges of each wall may have a seal component fitted within the exterior channel; when the walls connect, the seals mate or abut and the seal is formed. The seals used on opposite frame members may be different; one may be a protruding male' seal and the other a less prominent female' seal shaped to receive the male seal of the adjacent wall in a complementary fashion.

Examples of such seals are shown in Figure 8. On the right hand side, a first seal member 71 is shown from one end, clipped into position between the flanges 17 of the right hand frame member 30. The first seal member 71 extends substantially the length of said frame member 30. The shape of the first seal member 71 is part-hexagonal in form, in the sense that it has five sides and one left open as shown. It protrudes outside of the channel of frame member 30 and a void is available underneath for the placement of other components or cables, which are otherwise obscured from view.

On the left hand side, a second seal member 73 is shown, which is likewise clipped into position between the flanges 17 of, in this case, the left hand frame member 40. This second seal member 73 is concave in shape and partially complements the shape of the first seal member 71. This means that when adjacent walls 10, 10' meet, there is a tight sealing engagement, as indicated in Figure 9. Again, a void is available beneath the second seal member 73 to enable components or cables to be placed and hidden from view.

The first and second seal members 71, 73 can be clipped into, and removed from, the flanges 17 easily and transported as part of the kit. In further embodiments, a magnetic strip can be applied along the length of a seal to aid engagement.

Figure 10 (a) shows such a seal 73 with magnetic strip and Figure 10 (b) shows the other type of seal 71 in position within frame member 30.

In some embodiments, a seal drive actuator can be located in the space beneath a seal and operated to extend the seal outwardly to make the sealing contact. Seal drive actuators can be manually operated or automatic.

In some embodiments, a seal mechanism is used in the upper, first frame member 10 to provide soundproofing between the wall and the ceiling. This is indicated schematically in Figure 11 where two alternatives (a) and (b) are shown, one manual and one automatic.

The seal mechanism 80 is fitted at least partially within the channel 15 of the first frame member 10.

In Figure 11 (a) a manual seal drive actuator 81 is shown connected within the channel of a side frame member, i.e. member 30 or 40, either between or under the flanges 17.

Positioning of the actuator 81 can be anywhere between the ends of the frame member 40, but is preferably located at a height suitable for easy user access. Operation is by means of a key or lever which drives a linking rod upwards to the seal mechanism 80 which abuts the ceiling. Movement of the key in the opposite direction will draw the seal mechanism 80 in the opposite direction, away from the ceiling.

In Figure 11 (b) an electric seal drive actuator 83 is used to drive the sealing mechanism 80. This can be operated by remote control, or automatically in association with a proximity detector which can also be located within one of the frame member's channels. The actuator 83 is connected within the channel of the first frame member 10 either between or under the flanges 17, and again can be adjusted to any suitable position between the ends. Being electrically operated, user access is not reguired, and hence it moves an arm to raise and lower the sealing mechanism 80 in response to control commands.

As with other components, the sealing drive actuators 81, 83 can be located within the channel without the need for welding.

Bottom seals can also be used to form a seal between the wall base and the floor, and driven by the same or a different actuator in the same way.

Another component that can fit within a channel is a cable cover. It fits within a channel in a sliding engagement. It permits cables to be hidden from view under the cover within the underlying space 13.

In other embodiments, the aforementioned seals and/or covers may connect to the frame members using mechanical clips and/or using magnetic means. Fcr example, the seals may contact the chamfered walls of the channel and be held in place by magnets provided within the edges of the seal adjacent the chamfered edges.

Figures 12 to 15 show different types of seal drive actuators as shown in and described with reference to Figure 11.

Figure 12 shows a first, manual actuator 81 which causes movement of one or more seals in response to user action. Tn this case, the actuator 81 can move two opposite edge seals, e.g. on top and bottom frame members, for acoustic sealing against the ceiling and floor, although the user can choose to seal only one edge. The manual actuator 81 is provided in the form of a self-contained cassette or cartridge 101 that encloses and protects mechanical components and which is dimensioned to slot within the channel of a frame component.

A lower flange 103, as shown in Figure 13, in use slots beneath the side flanges 17 of the channel and is dimensioned to be retained thereunder; specifically, the width of the flange is wider than the gap between the side flanges. First and second cables 105 project from the cassette at opposite ends and each has a fork connector 107 for attachment to respective linking rods (not shown) which translate linear movement to the seal (s) . Operation of the manual actuator 81 is by means of a removable key (shown as element 111 in Figure 13) which connects to drive boss 110; rotation of the drive boss 110 in one direction causes the cables 105 to move outwardly in opposite directions to effect sealing. Movement of the boss 110 in the opposite direction pulls the cables 105 inwards and opens the seal (s) . Positioning and adjustment of the manual actuator 81 within the channel length is by means of one or more grub screws 109.

As shown in Figure 13, the manual actuator 81 is a low-profile component that does not extend above or below the channel boundaries. Tt is easily replaced in the event of component failure.

Figure 14 is an electrical seal drive actuator 120, including an arm 123 movable by an arm mechanism between a first position and a second position (the latter being indicated in the Figure) by an electrical motor 125. In the second position, a force is imparted to the interior of a top or bottom sealing member to create the sealing. The motor 125 is responsive either to a remote control signal or a positional or proximity sensor and hence electronic circuitry and/or microprocessors for receiving, handling and processing said signals are also present within the actuator component 120, e.g. on a pob beneath the arm mechanism.

Figure 15 is a different electrical seal drive actuator 130.

It operates on a similar principle to that shown in Figure 14, in that it comprises an arm 133 movable by an arm mechanism between first and second positions, the latter being shown in the Figure, comprises a motor 135 and related circuitry.

The seal drive actuators of Figures 14 and 15 are all dimensioned to have a similar form factor to the manual actuator cartridge in order to slot within a channel. Each includes one or more grub screw(s) to permit adjustable fixing of uhe device within the channel at any intermediate point.

The motor 125, 135 and arm 123, 133 are arranged to be aligned in a generally linear form to keep the size and profile relatively low when in the frame member channel. Being stand-alone components, they can be easily transported and replaced.

As mentioned above, the electrical seal drive actuators 120, of Figures 14 and 15 can be operated by remote control or automatically, e.g. using a proximity sensor to cause the seal to expand or move when close to the adjacent wall or surface.

The proximity sensor can be magnetic, inductive or optical.

The proximity sensor can itself be a self-contained and stand-alone component for adjustable fixing within a frame member channel.

The aforementioned apparatuses are applicable to transparent partitions as they are for opague, i.e. wood or plasterboard ones. However, mounting glass to the aforementioned frame members in the manner shown in Figures 6 and 7 presents difficulties, particularly if this is to be performed at the end-user's location. One has to cut the glass edges for mounting on flanges 23. Further, the inner surfaces of the frame members will be exposed through the glass which reveals any imperfections, dirt and the fixing holes.

A still further embodiment will now be described with reference to Figures 16 to 18 which provides an adaptor member for use with a corresponding frame member to provide improved mounting of glass or other transparent panels.

The adaptor member 200 is shown in cross-section in Figure 16(a) positioned above one of the frame members, i.e. the top frame member 10. Figure 18(a) shows the same adaptor member in perspective view, when upside down. The adaptor member is an elongate channel or either metal or plastics material having a base wall 201, two perpendicular side walls 200, 203 and, at the ends of the side walls, a stepped mounting section 207. said stepped mounting section 207 comprises an inwards L-section with a horizontal seat part and a vertical end part. The spacing between said vertical parts is approximately the same as the spacing between the two mounting flanges 23 of the frame member 10; hence the L-sections locate over the flanges in the manner shown in Figure 18 (b) with the seat part on top of the flange and the vertical part inside. The two parts 10, 201 are thereby connected, although the connection is improved if the mounting flanges 23 and/or vertical parts are slightly inclined in opposite directions, e.g. with the flanges inclined inwards and/or the vertical parts inclined slightly outwards. Other mounting or clipping arrangements may be employed.

Figure 16(b) shows the adaptor 200 when mounted and it will be seen that a generally 90-degree mounting channel is provided either side to which the glass panel can be mounted securely, e.g. using adhesive. Figure 17 shows two glass panels 211 when so mounted. No cutting of the glass is required.

Further, all that is visible from the exterior (indicated by arrow 213) is the base wall 200 and hence any imperfections, dirt or holes on the frame member 10 are hidden from view.

The void 213 between the adaptor 200 and frame member 10 is also available for cabling. Figure 18(b) shows the assembled adaptor 200 and frame member 10 in perspective view.

The adaptor 200 can be used with any previous embodiment, and typically four would be provided to cater for the four frame members and gives the end-user the option of using the supplied kit with opaque panels or transparent ones, depending on their need. The adaptor 200 offers the end-user the opportunity to re-use the framework for different types of panels later-on also.

It will be appreciated that the foregoing are merely an examples of embodiments and just some examples of their use.

The skilled reader will readily understand that modifications can be made thereto without departing from the true scope of the inventions.
