Description

FURNITURE SYSTEMS This invention relates to furniture systems, including panel systems for use with office furniture, for example, desks or work stations.

In modern offices the provision of cabling to each work place or each work station is of great importance.

Such cabling is needed to provide power outlets for personal computers and other electronic equipment, further, phone cables and computer network cables must also be provided throughout an office environment. All of this cabling must be kept tidily and safely. This is necessary to prevent damage to the cabling and also to prevent trip hazards. It is also desirable to provide office furniture in a modular and easily changeable format. Such flexibility is also desirable for the cable management systems associated with the furniture.

It is an object of this invention to provide a furniture system which is easily adaptable and which can support a variable and potentially extensive amount of cabling. Further, the invention aims to make the attachment and removal of cable carrying trays and wired socket outlets both quick and simple.

According to one aspect of the present invention there is provided a furniture system comprising: at least one panel comprising at least one longitudinal open faced cavity, which cavity is arranged to accept body supporting fitment means so that a body can be supported by said panel.

Said cavity can be a re-entrant cavity.

Preferably said panel is slotted to receive at least one length of moulded channelling which defines said cavity.

Said length of channelling can be arranged to be locatable in the slotted panel by means of a push fit or more particularly a snap fit.

According to another aspect of the present invention there is provided a furniture system comprising: at least one length of moulded channelling including a longitudinal open faced re-entrant cavity, and a panel being slotted to receive said length of moulded channelling.

Said panel can be slotted to receive the length of channelling as a push fit or more particularly as a snap fit.

The channelling can be generally U-shaped.

The internal surface of the channelling can be tapered so that the spacing between internal side faces of the channelling is at its narrowest at the open face of the channelling.

External side faces of the channelling can be provided with one or more ribs or barbs. The ribs or barbs serve to hold the channelling firmly in place.

The channelling can be provided with one or more flange at its open end. Said flange can abut with a face of the panel when the channelling is inserted into an appropriate slot.

Preferably the channelling is made of a resilient material such as plastic. This aids the location and fixing of the channelling in the panel. Further, the strength and/or effectiveness of fixing provided by fitment means associated with bodies to be supported by the panel can be improved.

Said panel can be an integral part of a piece of furniture, for example a solid desk leg or the side panel of a cabinet.

Said panel can be a modesty, courtesy or privacy screen or panel.

Preferably said panel is a modesty/courtesy panel provided below a desktop or a work surface.

The furniture system can further comprise a cable tray.

Said body can comprise said cable tray. Said cable tray can comprise first fitment means which are locatable in said longitudinal cavity.

Said cable tray can have as first fitment means, a rearwardly directed upturned lug which is shaped to fit in said longitudinal cavity and to locate the tray as a hanging fit on the panel when the panel is substantially vertically located.

The furniture system can comprise a wired outlet box.

Said wired outlet box can comprise second fitment means arranged to be received in said longitudinal cavity.

Said second fitment means can be locking fitment means comprising one or more expandable locking means for locking said fitment means and consequently said wired outlet box in position.

Said locking means can comprise two substantially mutually parallel webs which in an unexpanded state can be pushed into said cavity. In an expanded state said webs are pushed apart and if the webs are located in said cavity, outside surfaces of said webs form an interference fit with internal side faces of the cavity.

Such an arrangement is particularly effective if said cavity has a re-entrant shape.

A slotted block member having scallops formed therein to accept a screw can be provided between said webs, the scallops being formed so that when an appropriate screw is driven into said slotted block, two halves of said slotted block member and hence the webs are forced apart.

The second fitment means can be arranged to be attachable to said wired outlet box as a snap fit or a push fit.

Said first, second and locking fitment means can be used individually to locate and attach any suitable body to a panel. A plurality of any one of or any combination of said first, second and locking fitment means can be used to locate and attach any suitable body to a panel.

Preferably said panel comprises two longitudinal cavities which are mutually parallel and spaced apart so that wired outlet boxes can be associated with one cavity and cable trays with the other cavity.

According to another aspect of the invention there is provided a cable management system for furniture comprising: a cable tray having fitment means; said fitment means being arranged to be locatable in a longitudinal open faced cavity provided in a substantially vertical surface of a piece of furniture or the like so that said cable tray can be attached to said surface and supported by a hanging fit.

With such a system, cable trays and wire socket outlets can be added to or removed from the panels of a furniture system as and when they are required. In this way the required number of cable trays and sockets can be provided in the desired positions.

An embodiment of the present invention will now be described by way of example only with reference to the accompanying drawings in which: Figure 1 is a perspective view of a furniture system comprising two work stations incorporating a panel system; Figure 2 is a section on line II - II of the panel system shown in Figure 1, but with a wired outlet box and a cable tray shown detached from the panel; Figure 3 is a section on the line II-II of the panel system shown in Figure 1; Figure 4 is a cross-sectional view of a piece of moulded channelling; Figure 5 is an isometric view of a locking fitment means; Figure 6 is a plan view of the locking fitment means; Figure 7 is a rear view of the locking fitment means; Figure 8 is a front view of the locking fitment means; Figure 9 is a section on line IX - IX of the locking fitment means shown in Figure 7.

Referring to Figure 1 a desk or work station typically comprises a work surface or top 1, legs 2, and a number of panels 3.

The panels 3 are used to support cable trays 4 and wired socket outlets 5. Cabling C (shown as dotted lines) can be run from the floor up through legs 2, along the cable trays 4 and into the wired socket outlets 5. Further, the flex attached to plugs put into the sockets or cables hardwired into the sockets can be brought up around the back of the desk to supply power to the equipment being used. Cables C may also be run through apertures A provided in the panels so that the cables can be brought round in front of legs 2 or other supports.

The legs 2, panels 3, and worktops, 1 can be fixed together using any appropriate fixing methods.

Referring to Figures 1, 2 and 3 each panel 3 is provided with two mutually parallel longitudinal cavities 31.

Each of the longitudinal cavities 31 comprises a slot 31a formed in the panel 3 and a length of moulded channelling 6 which is inserted into the slot 31a.

Referring to Figure 4 each length of channelling 6 is moulded in PVC plastic material which is both resilient and tough. The moulded channelling 6 is generally Ushaped and has a flange 61 at both the extreme ends of the U. The flanges 61 abut with the surface of a panel 3 when the moulded channelling 6 is pushed into position in a slot 31a. External side faces 62 of the moulded channelling 6 are provided with a plurality of longitudinal barbed shaped ribs 62a. When a length of channelling 6 is pushed into an appropriate slot 31a in the panel 3, the barbed shaped ribs 62a serve to hold the length of channelling 6 firmly in position.

The internal surface of the channelling 6 has a reentrant shape. That is to say if another object is positioned in the channelling 6 and its outer surface is shaped so as to closely fit with the inner surface of channelling 6, then the object cannot be removed by pulling outwards without deforming either the object or the length of channelling 6.

The internal side faces 63 of the channelling 6 are tapered inwards towards the opening in the channelling 6. This means that the channel formed by the channelling 6 narrows towards an open front face 65 of the length of channelling 6. Each interior side face 63 has a taper angle of 10 (with respect to a line drawn perpendicularly through a base 64 of the channelling 6).

Referring to figure 2, each cable tray 4 comprises first, second, third and fourth side walls 41, 42, 43 and 44, a base 45 and a rearward upturned lug 46. Adjacent pairs of side walls 41, 42, 43, 44 and the base 45, form 3 longitudinal compartments into which cables can be laid.

This means that cabling of different types can be accommodated separately. The third and fourth side walls 43 and 44 comprise bent over portions 43a and 44a respectively. These bent over portions 43a and 44a serve to partially enclose the largest of the longitudinal compartments formed by the cable tray 4. A projection 47 is formed at the junction of the fourth side wall 44 and the base 45.

A cable tray 4 can be located on and hung from a panel 3 due to the co-operation between the lug 46 formed on the cable tray 4 and the cavity 31 formed in panel 3.

Referring to Figures 2 and 3, when the cable tray 4 is hung in position on the panel 3 the lug 46 is located in the longitudinal cavity 31. An extreme portion 46a of the lug 46 contacts with an internal corner 63a of the channelling 6. An internal corner 46b formed between the fourth side wall 44 and the lug 46 is in contact with and closely fits a nose 63b formed by one of the flanges 61 and one of the internal side faces 63 of the channelling 6.

When the cable tray 4 is hung in position, the fourth side wall 44 of the cable tray is spaced from the panel 3 due to one of the flanges 61 being sandwiched between the fourth side wall 44 and a face of the panel 3. The cable tray 4 is held firmly in the correct orientation because the projection 47 abuts with the face of the panel 3. The weight of the cable tray 4 and any cables laid in it serve to push the projection 47 against the panel 3.

The configuration of the lug 46 and the cavity 31 as defined by the length of channelling 6 is such that the cable tray 4 is held in position.

The lug 46 cannot be removed from or inserted into the cavity 31 when the cable tray 4 is in a substantially horizontal position but is easily insertable and removable if the front 4a of the cable tray 4 is lifted upwards. The cable tray 4 must be rotated into and out of position and gravity prevents the cable tray from accidentally or unintentionally being dislodged.

Each wired socket outlet 5 is held in position on the panel 3 by a locking fitment means 7. A locking fitment means 7 can be clipped into a recess 51 provided in the rearward side of each wired socket outlet 5.

Two webs 71 of the locking fitment means 7 can be in an expanded or an unexpanded state. When the webs 71 are in an unexpanded state they can be pushed into the cavity 31 formed in the panel 3. This allows the locking fitment means 7 to be located in the channelling 6.

Likewise, when in an unexpanded state the locking fitment means 7 can be easily removed from the channelling 6.

However, when the webs 71 are in an expanded state the locking fitment means 7 cannot be introduced into or removed from the channelling 6. In this way the wired socket outlets 5 can be securely attached to the panels 3.

The webs 71 are in the unexpanded state in Figure 2 and in the expanded state in Figure 3.

The locking fitment means 7 is shown in more detail in Figures 5 to 9.

The locking fitment means 7 comprises a flat generally rectangular main body 72, two parallel edges of which are provided with upstanding ridges 73. The two webs 71 are disposed substantially parallel to the ridges 73 and equispaced from a centre line of the main body 72. A rectangular recess 74 is provided centrally in an upper surface of the main body 72. A slotted block member 75 is provided below the rectangular recess 74. The slotted block member 75 comprises two halves 75a and 75b. Each of the halves 75a, 75b is formed integrally with a respective one of webs 71. The two halves of the block member 75a, 75b are formed on the internal faces of the webs 71 so that the two halves of the slotted block member 75a, 75b face one another.

A scallop 76 having a maximum radius of 1.6mm and having a taper angle of 10 is formed in each of the opposing faces of the two halves of the slotted block member 75a, 75b. The scallops are so dimensioned so that a No. 8 self-tapping screw can be screwed into the slotted block member 75 to spread apart the webs 71. The rectangular recess 74 is dimensioned to accept the head of the screw when it is fully screwed into the slotted block member 75.

The locking fitment means 7 is a one piece plastics moulding. Polypropylene is the preferred material.

When the locking fitment means 7 is in an unexpanded state, that is to say when there is no screw inserted in the scallops 76, the external faces of the web 71 are substantially parallel. In the unexpanded state the webs 71 can be easily inserted into the cavity 31 formed in the panel 3.

Once the locking fitment means 7 has been inserted into the cavity 31, a No. 8 screw can be screwed into the scallops 76 thereby forcing apart the webs 71. The locking fitment means 7 is then in the expanded state.

The webs 71 are forced apart because the hole formed by the scallops 76 is tapered and narrows towards the end 75e of the slotted block member 75 which is spaced from the main body 72.

Referring to Figures 2 and 3 when the locking fitment means 7 is located and fixed in the moulded channelling 6, the webs 71 are in an expanded state and form a close fit with the internal side faces 63 of the channelling 6. Further, internal corners 7la formed where each web 71 meets the main body 72, closely fit with the respective nose 63b of the channelling 6. The upstanding ribs 73 abut with the face of panel 3 when the locking fitment means 7 is screwed into position.

Once the locking fitment means 7 has been secured in position on the panel 3, the wired outlet box 5 can be clipped onto the locking fitment means 7. The main body 72 of the locking fitment means is accepted into the recess 51 formed in the wired outlet box 5 and provides a clip or push fit sufficient to hold the wired outlet box 5 in position.

The panel 3 can be made of covered chipboard, medium density fibre board or any other suitable material.

Items other than cable trays 4 or wired socket outlets 5 can be affixed to a panel in a similar way to that described herein.

Similarly, suitable grooves may be provided in any suitable surface instead of panels below a worktop. For example, above desk privacy screens can be provided with suitable grooves and any suitable equipment can be fixed to the panel using the fitment means described herein.

Alternatively suitable grooves could be provided on the external surfaces of drawer cabinets, solid desk legs or any other pieces of furniture.

Although the grooves are preferably formed in substantially vertical surfaces, the arrangement described can be used on surfaces at any orientation.
