Description

A VISUAL DISPLAY UNIT MOUNT

FIELD OF THE INVENTION

The present invention relates to a visual display unit mount, more particularly for monitors or similar.

BACKGROUND

The amount of time that people spend interacting with visual display units (VDUs) has seen a rapid increase in recent years. Many users in particular spend much time working or using screens, televisions or other visual display units in order to work, rest or play.

To allow a user to view a VDU comfortably, it is common for the VDU to be mounted on an adjustable mount. Such a mount consists of several components that are adjustable relative to one another. Once adjusted to suit the user's preferences, the components need to be able to retain the user's preferred configuration.

Traditionally, this is achieved through ensuring that there is sufficient friction between the components. However, this friction can lead to a number of difficulties in adjusting the VDU.

Firstly, the user must be able to apply sufficient force to the mount to overcome the friction between components. This force must be applied over the course of the adjustment, and often results in the VDU travelling beyond ("overshooting") the user's preferred configuration, meaning that they must repeat the process several times before the preferred configuration is achieved. Secondly, the user must be able to apply force in the required orientation. This can be awkward for certain types of motion, in particular, "lifting" the VDU to adjust its height. Thirdly, the user must often hold several components simultaneously in order to achieve relative movement of those components. For example, the user may have to secure the base of a monitor stand with one hand whilst adjusting the height of the screen with the other hand.

These problems associated with adjusting the position of VDUs are exacerbated by the trend towards VDUs with bigger screens. For example, such VDUs tend to weigh more, which means that adjustable mounts for such VDUs require a greater holding force (e.g., friction) between components to maintain a user's preferred configuration, and hence require a greater force to adjust them. In addition, the greater size of the VDU can mean it is more difficult to adopt a suitable hold on the VDU or mount to achieve adjustment of the mount.

It is common for VDUs to be positioned at a distance from a user, for a number of reasons. Spacing the VDU from the user is necessary to achieve a comfortable viewing distance, which will not strain the user's eyes. For computer monitors used for work, this viewing distance is typically 50 to 60 cm. Spacing the VDU from the user may serve other purposes as well. For example, it is common for computer monitors to be positioned at the back of a desk to allow space for computer peripherals, such as a keyboard and mouse, and to allow space for documents which the user may need to consult and/or work on.

The above problems are particularly acute when the VDUs are positioned at a distance. For example, to access a VDU at the back of a desk it is necessary to reach across the desk (which can be a considerable distance), whilst applying a suitable force to the VDU or VDU stand. In addition, it is usually not possible to adjust the position of the VDU from the normal viewing position, meaning it is necessary to carry out several iterations of adjusting the position of the VDU and checking whether the preferred position has been reached.

These problems associated with the positioning of VDUs are of particular significance to certain groups in society, such as children, the elderly, the infirm and, in particular, people with disabilities. For example, it is often difficult for people with disabilities (such as wheelchair users) to reach across a work desk to adjust their monitors. More generally, the above problems may affect people with impaired dexterity and/or strength.

Thus, there exists a need to provide a more easily adjustable mount for a VDU and, in particular, an adjustable mount suitable for people with disabilities.

Due to increasing population pressures, increased numbers of people are finding that living or working space is at a premium. This applies, in particular, to office environments. VDUs can take up a significant fraction of a user's workspace, especially for users that use multiple VDUs. Technological advances do much to mitigate the effects of limited space whereby users can take advantage of technology to entertain in manners not available previously. Attendant problems of this combination of factors relate to maximisation of technological advances, for minimum expense in a world of limited resources, and without cluttering workspaces and living spaces with technology. Miniaturisation is a growing trend, but is not suitable for all technology and in fact, as noted above, screens have tended towards increases in size.

Given the growing importance of space saving, it is important that, in addition to providing a more easily adjustable mount for a VDU, the mount should be relatively compact.

At its most general, according to a first aspect of the present invention there is provided a visual display unit mount, comprising: a base, a visual display unit bracket, a control, and an arm, wherein position of the arm is electrically controllable by a user through use of the control.

Suitably, the visual display unit mount comprises:

a base;

a column, extending from the base and rotatable relative to the base;

an arm, mounted on the column and movable relative to the column;

a visual display unit bracket, mounted on the arm and movable relative to the arm;

a first actuator for moving the visual display unit bracket relative to the arm; a second actuator for moving the column relative to the base; and

controlling means, for controlling the first and second actuators.

By "visual display unit" (VDU) we mean an electronic device having a video screen such as, for example, a computer monitor or a television. In preferred embodiments, the VDU is a flat-panel display, e.g., a flat-panel computer monitor or flat-panel television. The screen may be, for example, a liquid crystal display (LCD), a plasma display, or an electroluminescent display (ELD).

Advantageously, the visual display unit mount of the present invention allows a user to adjust the position of a visual display unit via controlling means, as well as/instead of manipulating the VDU or VDU mount directly. This has the advantage that the user can adjust the position of a VDU at a distance, mitigating the problems identified above.

Suitably, the mount is articulated such that articulated joints are in place between the arm, base and bracket (collectively referred to herein as "parts"). By "articulated joints" we mean a joint which allows relative movement of two parts.

These articulations allow the parts to assume a plurality of positions with regards to each other and consequently allows the visual display unit (VDU) to assume a plurality of positions with regards to the base. Advantageously, in this way a user may reposition a VDU, such as a television screen or computer monitor when and as required. For example the user may reposition the VDU for viewing from a remote location within a room, or for others to enable their viewing of the VDU.

Controlling Means

The visual display mount comprises controlling means, which control the actuators. Advantageously, the controlling means allow a user to adjust the position of the screen without having to manipulate the VDU or VDU mount directly. This is particularly advantageous for people with disabilities, because the present invention allows controlling means to be located at a convenient position for them, appropriate to their needs.

Controlling means take the form of an input device having a user interface, which a user may control to operate the actuators. Suitable user interfaces include, for example, joypads, buttons or joysticks. For example, the user interface may be a joystick or joypad, having up, down, left and right directions, wherein the up and down directions control the first actuator and the left and right directions control the second actuator (or vice versa). Advantageously, such user interfaces provide a simple and intuitive system for a user. For example, joypads, buttons and (in particular) joysticks are relatively simple for people with low or impaired dexterity (such as people with certain disabilities) to use.

In one embodiment, the control is locally provided. For example in some

embodiments the control may be a set of switches or buttons that relate to various movements or articulations of the mount.

In preferred embodiments however the control consists of a rocker control, having either internal analogue or digital switches that are activated by a single pad in order to mimic potential movements of the mount.

Advantageously the control is remotely provided by inclusion of wireless connectivity, such as shortwave radio waves, to include BLUETOOTH (Trade Mark). In this way the user may be situated remotely from the VDU and able to ensure that the VDU is aligned and oriented for optimal viewing. In particular this may enable a disabled user to operate and manipulate the VDU's orientation so that the user may derive maximum enjoyment.

As stated above, the controlling means may comprise a local control (i.e., a wired input device (controller), which is attached to the VDU mount to control the actuators). Such a local control may be an input device attached directly to another part of the VDU mount, e.g., the base, column, arm or bracket. Alternatively, the input device may be attached indirectly to another part of the VDU mount, e.g., the base, column, arm or bracket. For example, the input device may be indirectly attached through a wired connection to the base, column, arm or bracket, i.e., a peripheral component attached through a wire. Preferably, the local control is attached to the base.

In embodiments in which the input device is indirectly attached to another part of the VDU mount through a wired connection, the wired connection may include a removable electrical connection to that other part. For example, the removable electrical connection may be a Universal System Bus (USB) connector which removably connects with a USB port in the base, column, arm or bracket (most preferably, the base). Advantageously, the indirect attachment allows the local control to be positioned at a distance from the visual display unit mount, at a position convenient for the user. This is particularly advantageous for people with disabilities.

More generally, in preferred embodiments of the present invention the visual display unit mount includes a USB port. Advantageously, providing the VDU mount with a USB port allows peripherals to interface with the computer via the VDU mount, without the user having to access the USB ports of the computer (which can be difficult to reach). More generally, the visual display unit mount includes an electrical connection port, for interfacing with peripheral components. As stated above, the controlling means may be a remote control system, comprising a remote control transmitter (i.e., a wireless input device (controller), which does not have to be attached to the VDU mount to control the actuators) and a receiver.

Advantageously, a remote control system allows a user to adjust the VDU mount via the actuators at a distance. This can be useful when viewing the screen at great distance (for example, when using the VDU to watch television, or a film). It is particularly useful for people with disabilities, who may be unable to reach the VDU mount or VDU to achieve a desired viewing position, for the reasons discussed above.

Preferably, the remote control transmitter has a removable battery pack.

Advantageously, this allows an empty or low-charge battery to be replaced with a charged battery pack, without the inconvenience of requiring the whole remote control transmitter to be plugged-in to be recharged.

Preferably the removable battery pack is rechargeable. In especially preferred embodiments, the VDU mount has a port for charging the removable battery pack. In the most especially preferred embodiment, the VDU mount has a USB port. For example, the battery charging port and the remote control transmitter may both have a USB slot, and the removable battery pack may have a USB connector ("plug") for removably inserting into the USB slot.

In especially preferred embodiments, the controlling means comprise a local control and a remote control. These controls may have any of the optional and preferred features described above. Advantageously, providing both a local control and a remote control gives the user excellent flexibility in terms of how to adjust the screen. In particular, if the remote control cannot be used (for example, if the remote control transmitter is dropped so that it cannot be picked up, is lost, or is out of charge), it is still possible to adjust the screen using a local control. This can be of particular importance to people with disabilities, who may not be able pick up the remote control transmitter easily if it is dropped. Furthermore, the flexibility of use allows the method of control to be tailored to suit a person's disabilities.

In the most especially preferred embodiments, the controlling means comprise a local control which is directly attached to another component of the visual display mount, a local control which is indirectly attached, through a wired connection, to another component of the visual display mount, and a remote control. These controls may have any of the optional and preferred features described above. Advantageously, providing three different controls provides the user with excellent flexibility in terms of how to adjust the screen. As above, if the remote control cannot be used (for example, if the remote control transmitter is dropped so that it cannot be picked up, is lost, or is out of charge), it is still possible to adjust the screen using an indirectly attached local control, which can be positioned at a distance from the visual display unit mount convenient for the user. In addition, if it is not possible to use the remote control and/or indirectly attached local control, or it the user prefers, the user may adjust the position of the visual display unit using the directly attached local control. Having these different forms of control is particularly advantageous for people with disabilities, who may not be able pick up the remote control transmitter easily if it is dropped, for example. Furthermore, the flexibility of use allows the method of control to be tailored to suit a person's disabilities.

In embodiments comprising both a local and a remote control, software or hardware determines how to process simultaneous (and, in particular, conflicting) signals from the separate controls.

Arm

The arm is movable relative to the column. Suitably, this motion corresponds to changing the orientation of the arm relative to the column.

Preferably, the arm is pivotable relative to the column. Suitably, the pivoting motion occurs about an axis transverse (e.g., perpendicular) to the rotational axis of the column.

In embodiments where the arm is pivotable, the arm may be mounted to the column via an articulated joint, such as a pivot or hinge. Mounting the arm to the column via an articulated joint allows the angle of the arm relative to the column to be adjusted. Advantageously, in embodiments where the column extends upwards of a horizontal surface, adjusting the angle of the arm relative to the column alters the height of the VDU relative to the surface.

The arm may be attached to an external surface of the column. Alternatively, the arm may be attached within the column, and extend out of the column through an aperture e.g., a slot. Advantageously, attaching the arm within the column allows the attachment mechanism to be shielded from tampering, damage, dirt and dust.

In preferred embodiments, the arm comprises:

a bracket-attachment portion, to which the VDU bracket is mounted;

a first arm segment, having one end pivotably connected to the bracket attachment portion and the other end pivotably connected to the column;

a second arm segment, with one end pivotably connected to the bracket attachment portion and the other end pivotably connected to the column; wherein the first arm segment and second arm segment are oriented in the same direction. In other words, the first and second arm segments are parallel, such that they form a parallelogram. Differently stated, the arm is mounted to the VDU bracket and column by a parallel four-bar linkage, more specifically, a planar quadrilateral linkage.

Advantageously, an arm having such an arrangement allows the height of the bracket-attachment portion relative to the base to be adjusted without altering the angle of the visual display unit bracket relative to the base. In particular, this arrangement allows easy manual adjustment, by minimising the surface area of moving surfaces in contact with one another and hence minimising friction (friction only takes place at the pivotable connections), whilst maintaining the preferred orientation of the arm relative to the column.

The arm may be pivotable relative to the column over a range of, for example, 30 ° or more, 45° or more, 60 ° or more, 75° or more, or 90° or more. This range of adjustability advantageously allows a user great choice in their preferred viewing configuration.

Suitably, the visual display unit mount incorporates biasing means to maintain the orientation of the arm relative to the column.

In preferred embodiments, the biasing means is a spring. For example, the biasing means may be a spring with one end attached to the column, and the other end attached to the arm, which allows the orientation of the arm relative to the column to be maintained. In such embodiments, the end of the spring attached to the column is positioned above the end of the spring attached to the arm ("above" denoting position relative to gravity). In embodiments having a bracket attachment portion and arm segments (e.g., when the arm is mounted to the VDU bracket and column by a parallel four-bar linkage), it is preferred that there is a spring, with one end of the spring attached to the column and the other end of the spring attached to the first or second arm segments. In some embodiments, the visual display unit mount has an arm-attachment part, wherein the arm is pivotably mounted to the arm-attachment part, and the arm- attachment part is rotatably mounted to the column. This provides an additional degree of control, and allows the user to rotate the arm relative to the column without having to use an actuator. In preferred embodiments, the VDU mount comprises a bearing to reduce friction during rotation of the arm-attachment relative to the column.

In one embodiment, the visual display unit mount comprises a second arm connected to a second visual display unit bracket, having the features described above.

Advantageously, this provides a user with great flexibility, and can allow more than one user to use the same mount, thus saving space and expense.

In such embodiments, it is preferred that the arms and brackets are independently adjustable.

Column

Suitably, the column is rotatable relative to the base. For example, the base may extend in a plane, with the column extending along and being rotatable about an axis transverse (e.g., perpendicular) to the plane.

In preferred embodiments the column is continuously rotatable relative to the base, i.e., the column can rotate through 360 °. Advantageously, allowing the column to rotate through 360° provides the user with good flexibility, in terms of their preferred VDU configuration. For example, in an office environment, the user may be able to rotate the VDU to display their screen to another person sitting opposite them. Preferably, the VDU mount comprises a bearing to reduce friction during rotation of the column relative to the base. Advantageously, this minimises the power required to rotate the column relative to the base, and minimises wear caused by such rotation.

In preferred embodiments, the base has an upstanding housing (e.g., a shaft) and the column is mounted within and rotatable within the housing. Advantageously, mounting the column within an upstanding housing provides additional support to the column, reducing the turning moment caused by a VDU mounted to the VDU mount.

In some embodiments, the column is height-adjustable. Height adjustment may be achieved, for example, through a telescopic mechanism. Such a telescopic mechanism may comprise a column which can be moved (e.g., lifted) within an upstanding housing (e.g., shaft) of the base (the upstanding housing being as described above). Additionally or alternatively, the telescopic mechanism may comprise a column which has telescoping sections (i.e., which move past one another in a telescopic manner).

In embodiments where the column's height is adjustable, it is preferred that the VDU mount includes a mechanical lock to lock the column at a given height.

VDU Bracket

Preferably the VDU bracket may be provided independently wherein for example the VDU may be attached to the mount either using an existing fitting which will correspond with a 'universal fit' bracket that enables a plurality of VDU fittings to be encompassed within the bracket and the mount.

The VDU bracket is movable relative to the arm, with the motion controlled by the above-mentioned first actuator. Suitably, this motion facilitates "tilting" of a VDU mounted to the VDU mount. In other words, if the VDU bracket is considered to extend in a plane, the angle between the plane of the VDU bracket and the arm can be varied.

In some embodiments, the angle between the plane of the VDU bracket and the arm can be varied over a range of, for example, 30 ° or more, 45° or more, 60° or more, 75° or more, or 90 ° or more. Advantageously, this range of angles allows good flexibility to the user in terms of their preferred viewing position. Preferably, the angle can be varied over a range of 90° or more, since this provides particularly good flexibility to the user. Preferably the arm is adapted to allow movement of the VDU bracket in more than one plane. For example the bracket may adjust or reposition for height and/or horizontal distance and/or rake in relation to a fixed point.

In other words, the arm may be used to adjust the height of the VDU bracket (as described above), and the VDU bracket may be moved relative to the arm so as to adjust the angle of the bracket relative to the arm.

In yet further embodiments, the bracket and/or mount may allow rotation of a VDU mounted to the VDU mount, so that the VDU may be viewed in horizontal or vertical orientations. In other words, in these embodiments the VDU mount allows "spinning" of a VDU mounted to the VDU mount. Differently stated, the visual display unit mount may allow the VDU bracket (and a VDU mounted thereon) to be rotated about an axis transverse to (e.g., perpendicular) the plane of the VDU bracket. For example, it may be possible to spin the VDU bracket relative to the arm so that a VDU mounted thereto can switch between horizontal ("landscape") and vertical ("portrait") orientations. Advantageously, this allows the user to switch their screen orientation to suit the particular task they are carrying out. For example, if the user wishes to read a portrait document they can spin the screen to a vertical orientation. Preferably, the VDU mount allows a VDU mounted thereon to be rotated 360° about the axis extending from the plane of the screen of the VDU. For example, the VDU bracket may rotate 360° about an axis transverse (e.g., perpendicular) to the plane of the bracket. Actuators

The motion of the VDU bracket relative to the arm, and column relative to the base, is controlled by first and second actuators respectively.

In embodiments in which the column is height-adjustable, the visual display unit mount preferably comprise a third actuator for adjusting the height. In embodiments in which the VDU mount allows the VDU bracket to be rotated about an axis transverse to the plane VDU bracket, the visual display unit mount preferably comprises a fourth actuator for actuating this rotation. In embodiments in which the column is height-adjustable and in which the VDU mount allows a VDU mounted thereon to be rotated about an axis extending from the plane of the screen of the VDU, the visual display mount may comprise both the third and fourth actuators. In preferred embodiments, the actuators comprise motors, in particular, electric motors. In such embodiments, coupling of the power from the motors to the relevant parts of the VDU mount can be achieved in a number of different ways.

In preferred embodiments, the actuators comprise worm gear apparatus to couple power from the motors to the relevant parts of the VDU mount. Worm gear apparatus is made up of a worm (which takes the form of a screw) which meshes with a worm gear (which is similar to a spur gear). Advantageously, worm gears provide a precise, smooth, controlled movement. Alternatively or additionally, one or more parts of the mount may be hydraulically movable. In one embodiment, for example, the actuators comprise hydraulic elements. For example, in one embodiment, the arm is a hydraulic arm and is movable relative to the column by way of a hydraulic actuator. Ideally articulations are manipulate, and/or the arm, base or bracket is electrically or mechanically controllable. In a preferred embodiment, the articulations (i.e., the articulated joints) are able to be moved electrically.

Suitably, the VDU mount is connectable to a source of electrical power to power the actuators. For example, the VDU mount may have an electrical plug for connecting to an electrical socket, or may have a USB adaptor for connecting to a computer.

Other Options, Preferences and Aspects of the Invention

Preferably, the VDU mount is attached to a horizontal surface such that the VDU may be mounted onto a table. The discussion above is formulated in terms of such an embodiment. Alternatively, the VDU mount is attached to a vertical structure, such that the VDU can be mounted onto a wall. The skilled person will understand that, for such embodiments, certain relative spatial terms (such as "height") used above should be modified.

Preferred embodiments may also allow the VDU to be attached to either as required, wherein the mount may be provided in a kit of parts allowing the mount to be adaptable to a plurality of surfaces or structures. For example some embodiments of the base may be provided or include a clip or clamp.

Such a mount in particular permits use of a dual purpose smart television or monitor, wherein the mount for example enables a user to use the monitor at a desk and subsequently move the mount to enable the user to view a television from a more comfortable location, so maximising technology in limited spaces.

In a second aspect, the present invention relates to a VDU apparatus comprising a VDU mounted to a VDU mount of the first aspect. In a third aspect, the present invention relates to a kit of parts comprising the components of the first aspect of the present invention.

In a fourth aspect, the present invention relates to a remote control having a removable battery pack, wherein the removable battery pack is connected to the remote control with a USB connector.

The invention has been described by way of examples only and it will be appreciated that variation may be made to the above-mentioned embodiments without departing from the scope of invention.

With respect to the above description then, it is to be realised that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.

DETAILED DESCRIPTION

Figures 1 to 5 show an embodiment of a VDU mount in accordance with the first aspect of the present invention.

The embodiment shown in Figure 1 has a base 1 with an upstanding shaft 2, which receives upstanding column 3. The column 3 is rotatable through 360° relative to the base 1 about an axis running perpendicular to the plane of the base, through the centre of the column. This rotation is achieved by a motor (shown in Figure 2). The shaft 2 acts as a "sleeve" around the column 3, which acts to reduce the moment caused by other overhanging parts of the mount, and to protect the motor and other moving components from damage, tampering, dirt and dust.

Extending from the column is an arm 4. The arm 4 comprises a four-bar linkage. This consists of a top arm segment and a bottom arm segment, each with an end attached within the column 3 through pivots 5. The arm segments extend through a slot in the column. The other ends of the arm segments are attached to a bracket- attachment part through pivots. This arrangement allows a user to adjust the height of the VDU bracket, without adjusting the tilting angle of the bracket. Two coiled springs, each with one end attached to within the column 3 and the other end attached to the bottom arm segment, maintain the arm 4 in its preferred orientation.

A VDU bracket 6 is attached at the end of the arm 4. This bracket 6 can be tilted relative to the arm 4 by a motor (shown in Figure 2). The bracket 6 has holes for receiving a VDU.

The base 1 is provided with a joypad 7 (a local control), to control relative movement of column 3 and VDU bracket 6. Either side of the bracket, there are USB ports 8, which can receive a wired input device, such as a joystick.

As shown in Figure 2, the embodiment uses worm gears 9 and two motors 10 to achieve relative motion of the bracket 6 and arm 4, and column 3 and base 1 . The worm gears and motors require fewer components and achieve a smoother more precise movement than would be achieved in embodiments using hydraulics or friction fit components.

The pictured and preferred embodiment of the mount provides a fully adjustable visual display unit, or monitor, stand that smoothly repositions a user's monitor to a more desirable angle whilst they are sat in a comfortable working position.

A worm gear also locks the stand in place so that there is no risk of the visual display unit monitor (not shown) tilting forwards over time. As worm gears provide a precise, smooth, controlled movement they are ideal for both movement in the X and Y plane.

Another embodiment (not shown) uses a motor and worm gear to rotate the monitor 360^e through the X plane, and hydraulic pistons to tilt. Ball bearings 1 1 allow the column, and hence a monitor attached to the mount, to easily rotate whilst not transferring any weight from the monitor through the mechanisms. Preferably, the two bearings 1 1 stop the arm from tilting forwards under the weight of the monitor, wherein a motor rotates the arm, which sits between the two bearings 1 1 to allow it to easily rotate. Two strong springs 12 keep the monitor at the desired height and the bearings 1 1 take strain from the monitor leaning forward, allowing it to rotate smoothly. Further embodiments use a universal plate that allows the majority of flat screen monitors to be easily fitted into place. Such an embodiment may still rotate, but uses a worm gear and motor in the arm which allows very fine adjustments to be made to also reduce thickness of the mount. Such worm gears are ideally made from metal to be able to take full weight of the monitor.

The pictured embodiment includes a universal monitor plate wherein an existing monitor is attached to the mount, for example using four screws, being universal with holes 100mm and 75mm apart.

Movement may be achieved using a remote control (shown in Figure 6) with no significant effort or awkward movement required from the user. As pictured in Figure 6 the mount includes a 4-button remote 6 that has a (universal serial bus) USB port for recharging a removable battery pack provided with a USB connector.

In other embodiments a USB or THUNDERBOLT (Trade Mark) hub provides easy access and increases available ports and is located at a side to keep the mount front uncluttered. As seen in Figure 4 an internal rechargeable battery for a wireless remote, can be recharged using the USB ports 8 on the base front.

The visual display unit also includes two local controls. The first, consisting of a joypad 7, is attached directly to the base 1 of the mount. The second, consisting of a joystick (shown in Figure 7), is attached through a wire to the base of the mount. Up/down motion of the joypad/joystick causes the first motor 10, to turn the worm 9 so as to tilt the bracket up and down relative to the arm. Left/right motion of the joypad/joystick causes the second motor 10 to turn the worm 9 so as to rotate the column 3 relative to the base 1 .

A large base 1 provides weighting and stability to accommodate a range of monitor sizes. A metal rod acts as a pivot and also gives stability to the base. In some further embodiments the base is clamped to a desk (not shown) which significantly reduces the amount of space taken up by the monitor base. Extra support ribs can be added to allow heavier monitors. For larger size screens an additional gear can be added which will raise even heavy screens.

Figure 6 and 7 show different controls however it is envisaged a range of possible shapes are possible and/or desirable, all of which can be wired or wireless. In preferred embodiments a joystick allows a greater level of accuracy over fine movements and a 4-way joystick, (which may be included on the base, and/or operated remote controlled wireless or via a hard wire connection) allows a very precise movement to be achieved.

The pictured and preferred embodiment provides an electronically adjustable computer monitor stand and is well-suited for offices or organisations with a large number of computer monitors that require multiple user use.

The embodiment allows for effective hotdesking wherein multiple users are enabled to easily and quickly adjust monitor arrangement and/or orientation for personal use, so preventing discomfort and workplace injury.

In any event provision of a fully adjustable monitor stand aims to provide more comfort for users in an office environment. It will enable the user to move their monitor into an optimum position efficiently. The pictured embodiment is well suited to cater for as many different sizes and shapes of monitors as possible, to enable the monitor to be secured to the stand in a simple and safe way and be able to rotate the monitor through an X plane 360° and a Y plane 45° in both directions. Such bases may have a very small footprint, taking up much less space than a standard monitor stand when achieved using the clamp, but will need a suitable desk. Nylon straps or other durable webbing or similar flexible material may be provided and available to securely attach an existing monitor base with minimal effort, modifications or need for tools. Nylon webbing strap and buckle firmly secure the monitor in place. Such embodiments require minimal setting up, and attach to most existing monitor bases using two straps and do not require any modification to the existing monitor, and will work even if they do not have a universal plate fitting on the rear of the monitor. In the pictured and preferred embodiment however the monitor sits on a central circular plate that can be tilted 45^e forwards or backwards, this is sat on top of another base plate that can be rotated 360^e. Central column rotates, whilst the outer casing keeps it vertical.
