Abstract

The platform 1 has four legs 8 which are each individually adjustable in length to provide a stable support on an uneven surface, for example, a bed. Each leg extends from a corresponding socket 3 on the underside of the platform. The height of each leg is determined by tightening or untightening a knob 4 on the side of the socket in order to lock or unlock the leg member so that it can be fixed or extended/retracted in relation to the socket. A keyboard 10 may form an integral part of the platform. Alternatively, the platform may support and retain the keyboard in a recess (27,Fig.7). The keyboard may be connected to a remote computer via a cable (11,Fig.2) of longer length (2.5m) than conventional cables. A tiltable document support 13 may be hinged via pivot connections (14,Fig.6) to the platform and locked at an angle thereto to act as a book rest. The platform may also include a wrist support 9, a joystick 21, receptacles 22,23 to house a removable drinking utensil (e.g. a bottle,mug or cup), troughs 24,25 to house disks or books, an electronic games console, and a mouse pad. The keyboard may be liquid resistant.

Description

2352426 A SUPPORT FOR COMPUTER EQUIPMENT The present invention relates to

a support for computer equipment and, more particularly, to such a support which facilitates use of the equipment 5 when placed on an uneven surface, such as a bed.

If a person is lying or sitting up in bed it is difficult for that person to use a keyboard for a computer as it is not sturdy and is liable to move about.

US-A-4848710 discloses a support device for holding a monitor and a keyboard for use by a person lying on a bed. The support device has a main body which supports first and second shelves. Each shelf is inclined towards the person on the bed and a monitor and a keyboard is mounted on the first and second shelves respectively. The main body has a pair of side members so that the main body can span a person lying on the bed and wheels are provided on the base of the side members to enable the support device to be moved along the bed. However, such a support device is unwieldy, particularly with a monitor mounted on it. If the bed is uneven the support device cannot provide a level surface for the keyboard. Also, the angle of the shelves cannot be adjusted.

it is an object of the present invention to provide a support for computer equipment which overcomes the above mentioned disadvantages.

According to the present invention there is provided a support for computer equipment comprising a platform arranged to retain said computer equipment and having a plurality of legs, the legs being individually adjustable in length so as to enable the support to be stabilised when placed on an uneven surface.

Thus, a stable support can be provided on a bed where the bedclothes duvet can provide an uneven surface. This is particularly so when the bed is only partially made.

The support may hold or include a keyboard and a person who is sitting up in bed can easily use the keyboard as it is stable and level when the legs of 2 the support are suitably adjusted in relation to the uneven surface.

In order that the present invention may be more readily understood, reference will now be made, by way of example, with reference to the accompanying drawings, in which:

Figure 1 is an isometric view of a support according to the invention including a substantially rectangular flat member shown in its tilted, raised position; Figure 2 is an isometric view of the support showing the rectangular flat member in its retracted position; Figure 3 is a plan view of Figure 2; Figure 4 is a side elevational view of Figure 2; Figure 5 is a schematic sectional view of a locking arrangement for locking a leg member of the support; Figure 6 is a schematic sectional view of an arrangement for locking the rectangular flat member in a tilted position; and Figure 7 is an isometric view of a modified support.

Referring to Figures 1 to 6 of the accompanying drawings, a support 1' for use on a bed comprises a rectangular shaped platform 2. At each corner of the platform there is a leg socket 3 extending in a downward direction in relation to the platform with an adjustable knob 4 extending from a hole 5 in the side of each socket. The knob 4 has an exterior screw thread 6 which is engaged by an internal thread 7 on the side of the hole 5 which surrounds the knob. The knob 4 extends sufficiently into the socket 3 to make contact with a leg member 8 which extends from the socket, the knob exerting sufficient force to hold the leg member in place.

The platform 2 has a front portion 9 behind which there is a keyboard forming an integral part of the platform. The keyboard 10 is connected to a computer (not shown) remote from the bed by means of a cable 11 which extends from the rear of the support 1. The keyboard is of a type which is resistant to crumbs from food or spilt drink.

3 Behind the keyboard 10 there is a recess 12 for receiving a substantially rectangular flat member 13 forming a part of the platform 2 and which is pivotally movable in relation to the rest of the platform. The rectangular flat member is connected by pivot connections 14 to opposite sides 15 of the recess enabling the rectangular flat member 13 to be tilted towards or away from the keyboard 10. The pivot connections 14 comprise a pair of cylindrical stubs which extend from the end portions of opposite sides of the rectangular fiat member and are received by correspondingly shaped recesses in the recess sides 15. Hinged to the underside of the rectangular flat member 13 are two arms 16. The free ends 17 of the arms can engage racks 18 on the base of the recess 12. The rectangular flat member 13 also has a notch 19 along the side furthest from the keyboard 10.

The support 1 has a receptacle 20 on one side of the keyboard 10 for receiving a joystick 21. The receptacle 20 has a resilient clip arrangement (not shown) for releasably retaining the base of the joystick in the receptacle.

Behind the joystick receptacle 20 and towards one side of the platform 2 are two circular receptacles 22,23. The first circular receptacle 22 is suitable for holding the bottom portion of a glass, mug or can and the second circular receptacle 23 is suitable for holding the bottom portion of a large bottle, such as a 2-litre fizzy drinks bottle or a wine bottle. The bases of the first and second receptacles 22,23 are tilted slightly in order to provide better stability for the items that they are suitable for holding.

The platform 2 also has first and second rectangular troughs 24,25.

The first rectangular trough 24 is located in a far corner of the platform 2 and is behind the second circular receptacle 23. The second rectangular trough 25 is located to one side of the first trough 24 and behind the recess 12 for the flat rectangular member 13. Both troughs 24,25 are deeper than the circular receptacles 22,23 with the second trough 25 being larger and deeper than the first trough 24. These troughs may be used for holding disks, books or similar items.

4 In a preferred embodiment, the keyboard cable 11 is approximately 2.5 metres long so that it is of a sufficient length to reach the computer which is remote from the bed. Thus, the keyboard cable is of a longer length than a cable for a conventional keyboard.

In use, the support 1 is placed so that the bases of at least three of the leg members 8 rest on the surface of the bed. The support is positioned so that there are two leg members on either side of the body of a person when that person is in the bed even though the base of one of the leg members may not touch the bed. Any of the leg members 8 are then adjusted in height in relation to their leg socket 3 by the person untightening the relevant knob 4 so that the associated leg member 8 is freed. This enables the leg member to be extended further out of or retracted further into the socket 3. When the leg member 8 is of the desired extended length in relation to the socket, the knob 4 is tightened so that it locks the leg member to the socket. Thus, the leg members are adjusted until the base of all four leg members 8 are on the surface of the bed so that the support 1 is stabilised and provides a stable and secure platform.

The stable platform 2 enables drink containers held in any of the receptacles 22,23 not to easily spill their contents.

The support 1 can also be tilted towards the person by adjusting the knobs 4 so that the length of leg members 8 extending from the two front leg sockets 3 is less than the length of leg members extending from the two rear leg sockets.

The person tilts the rectangular flat member 13 from its retracted position (see Figure 2) by using a finger to engage the notch 19 in order to lift the member 13. The rectangular flat member 13 is rotated to the desired angle relative to the platform 2 and is held substantially at that angle by the free ends 17 of the arms 16 engaging the teeth of the racks 18. The raised rectangular flat member 13 can then be used to support documents, such as books and magazines, for ease of reading or typing. The base of such documents rest in a narrow gap 26 between the rectangular flat member 13 and the side of the recess 12 closest to the keyboard 10.

The person in the bed can then use the keyboard 10 to type the document supported by the raised rectangular flat member 13. The front portion 9 of the platform 2 supports the wrists when typing to prevent or reduce repetitive strain injury.

To retract the rectangular flat member 13, the arms 16 are rotated away frorn the racks 18 so that their free ends 17 do not engage the teeth of the rack and the rectangular flat member 13 is placed flat in the recess 12.

When the rectangular flat member 13 is in its retracted position a dinner plate and any associated cutlery may be placed on it, although any suitable item may be placed here.

The support 1 described is formed from hollow and/or light components so that it can be easily lifted on or off a bed.

Referring to Figure 7, in one particular modification, the support 1 a is shown without an integrated keyboard. Instead a recess 27 is provided for receiving a conventional keyboard.

Whilst a particular embodiment has been described, it will be understood that various modifications may be made without departing from the scope of the invention. For example, any suitable data entry device may be held by, or incorporated into, the support. The keyboard cable connecting the keyboard to a computer may be replaced by wireless communication apparatus, such as one incorporating an infra-red beam. The location of any of the receptacles and troughs may be located to suit and may be located to suit a left-handed person for example.

Individually adjustable legs of any suitable arrangement may be provided in order that person in a bed can have a stable support.

The arms and racks may be replaced by any suitable arrangement for locking the rectangular flat member at an angle relative to the rest of the platform.

6 The receptacle for the joystick may be replaced by a mouse pad which may be either an integral part of the platform or may be placed on the platform. A mouse would also be provided which is connected to the remote computer by a cable. Alternatively, the keyboard may be provided with a 5 button mouse.

The support may be adapted to hold a game console instead of a keyboard so that a 'person who is in bed can easily play computer games.
