Description:
A DESK FOR USE IN A VEHICLE

TECHNICAL FIELD

This invention relates to a desk which is configured for use in a vehicle. The desk is configured to be removable from the vehicle, conveniently stored within the vehicle and able to be engaged with elements of the vehicle when desired In order to provide a work station or surface within the vehicle.

BACKGROUND TO THE INVENTION

Many people perform work tasks whilst travelling between various locations during a working day or week. These Include for example sales people, contractors / builders, surveyors, truck drivers and delivery service people.

These people often undertake a significant amount of work In, or around their vehicle, especially in adverse weather conditions or when the vehicle may provide a more comfortable seating alternative.

ί

When working In a vehicle, a workers comfort and ability to perform tasks can be greatly enhanced by the presence of a flat stable surface / preferably positioned next to the driver's seat. This may allow the worker to use a laptop computer write notes, read maps or other business related documents or provide a tray for food and beverages.

To provide such a working surface, a wide number of desks for use in vehicles have previously been developed. These however, all have significant disadvantages.

One major disadvantage of currently available vehicle desks is that they are often heavy and awkward to install and position within the vehicle. Another substantial disadvantage of currently available vehicle desks is the conventional arrangement where a desk is positioned over and supported by the passenger seat of the vehicle. This results in the desk occupying significant room in the vehicle and disabling the passenger seat from accommodating a passenger.

An example of such a desk is United States patent no. 4,909,159 (US Ί59) which discloses a support table for a laptop computer which is positioned on the front seat of a vehicle. The support table has a horizontal support surface which is supported by a frame, with a pair of rear legs which rest on the passenger seat of the vehicle and a pair of front legs which are adjustable and extend downward to rest on the foot well of the vehicle. Whilst the support table disclosed in US '159 does provide a flat surface to work on, the table Is excessively bulky and when deployed In the vehicle, occupies the entire passenger seat. Furthermore, given Its size, the support table is also likely to be difficult to Install or remove from the vehicle, or manoeuvre within the vehicle. This is not desirable, as fn many cases a vehicle will be used for both work and family, requiring the vehicle desk to be removed from the vehicle frequently. Another example of a previous solution is provided in United States patent no. 5,973,917 which discloses a portable work station for use in motor vehicles. The workstation comprises a large, box-like cabinet, which also occupies the entire passenger seat when positioned in the vehicle. The workstation provides a computer tray which can be used to work from and an enclosed volume which can be used store a laptop computer or other business or work materials. The workstation also includes a pair of buckles or securing means which can be used to secure the unit to the front seat of the vehicle. Alternatively, the computer tray may be attached to an articulated cantilever system which projects out when the lid of the container is opened. The workstation disclosed has a similar disadvantage to that previously discussed, wherein when in use, it prevents the passenger seat from accommodating a passenger. Also, the workstation is of a substantial size, making it heavy and difficult to manoeuvre. There are a wide range of similar vehicle desks, all of which are positioned on and supported by the passenger seat of the vehicle. Further examples of these are: United States patent no. 5560676, United States patent application no. 20060091169, United States patent application no. 20080083351 and United States patent no. 5505139.

Each of the desks or work stations disclosed in these patents and patent applications are inconveniently dimensioned and when installed into a vehicle, occupy the entire passenger seat of the vehicle. Given the large size of each of the prior art desks and work stations, they are also likely to be excessively heavy, also proving difficult to manoeuvre in and out of the vehicle.

Furthermore, many of the currently available solutions do not extend substantially towards the driver's seat. This can make working on the work surface uncomfortable and cause back or neck problems if the driver has to rotate their body towards the passenger seat for considerable periods of time. A further problem associated with working or travelling In a vehicle for an extended period of time relate to eating in a vehicle. In these instances the absence of a table or tray can allow food and drink to collect on the driver's clothes or within the upholstery of the vehicle's interior; both of which proving unhygienic and unpleasant.

It would be beneficial to provide a desk for use in a vehicle which overcame the problems associated with the above products. In particular, it would be of advantage to have an improved desk available for use in a vehicle which could be collapsed or Otherwise have its volume decreased to assist storage of the desk in the vehicle when not in use. It would also be of advantage to have a desk which could be readily converted to support and retain work materials, food or any other items as required within a vehicle.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS The present invention is adapted to provide a desk for use in a vehicle, which includes a cabin with at least two seats and preferably a central console separating the two seats. Reference in general throughout the specification will be made to the present invention being used in relation to cars, although those skilled In the art should appreciate that the present invention may also be used with any vehicle which incorporates at least one seat and a central console or similar component within the vehicle.

The adaptable and compact nature of the present invention, in combination with its numerous stabilisation and comfort increasing features, offers a number of significant advantages over previous vehicle desk solutions. For example, the present invention is substantially lighter and easier to manipulate within a vehicle cabin. The invention Is also foldable and able to be made more compact than previous solutions to be conveniently stored. The invention may also be adjusted to suit a wide range of user and environmental requirements, Including supporting the desk against and attaching to various components of a vehicle's interior.

In a preferred embodiment, the desk comprises a work surface and at least one engagement projection, or support leg, arranged to be substantially perpendicular to the work surface and locate the desk relative to the vehicle when the desk is In Its in-use configuration, where the leg can be wedged between a seat of the vehicle and a vehicle central console to locate the desk relative to the vehicle. Wedging the projection between a seat and the central console provides an effective frictional engagement of the desk to the vehicle and thereby acts to hold or locate the desk in place when it is to be used.

In such an embodiment, the support leg also preferably has a deformable sheath surrounding and affixed to the leg in order to avoid causing damage to the interior of the vehicle when wedged between a seat and the central console. Optionally a range of removable deformable sheaths may be provided having a range of thicknesses to allow a user to adjust the padding around the support leg according to the distance between the seat and the central console In the vehicle. Preferably such a sheath is made from a foam material or rubber compound.

In one embodiment, an engagement projection may be formed by a tapering leg, with the width of this leg being at its greatest adjacent to the work surface of the desk. Tapering of a support leg allows the desk to be used with a wide range and number of vehicles having various configurations of central consoles and seats. Such a leg may be pushed downwards Into a gap between a seat and central console until it firmly holds the desk in place. In a preferred embodiment the desk has a single support leg only, however those skilled in the art will appreciate that providing a plurality of support legs is within the scope of the invention. In such embodiments the single leg is located substantially along a central line of symmetry of the work surface and adjacent to an edge of the work surface. By providing a single support leg in such an arrangement, this allows the desk to be pivoted or turned about the axis of the leg, allowing the desk to overlap or be moved away from a seat In the vehicle, whilst minimising the encroachment of the desk within the space below the desk, allowing this space to be used for other objects or users.

According to one preferred aspect of the invention, a work surface is provided by a single flat sheet of material, providing a simple and robust design that minimises the number of moving parts and components used. However in other embodiments the invention may be provided with a collapsible work surface, comprising at least two work sections rotatable on the same plane towards one another to collapse the surface and decrease Its size for storage.

In some embodiments which include collapsible work surfaces, the desk may Include a locking means for each pivot or connection of a work section to another work section. A locking means can be employed to lock the work sections in an arrangement parallel to and aligned with one another to form a substantially flat work surface. In a preferred embodiment a locking means may be formed by a sliding tab or bar located within a channel in the underside of the desk. This bar or tab may extend to span across two work sections to hold these work sections parallel to one another when the desk is in use. The extension of this tab or bar across the underside of two work sections thereby prevents these work sections being pivoted towards each other.

In a preferred embodiment the working surface may have a non-slip surface over substantially all, or a portion of, the surface. This allows notebooks, PDA's, maps etc to be gripped on the surface when the vehicle is In motion. 29ο It should be appreciated that the desk of the present invention has been developed for use by the driver of a vehicle when the vehicle Is stationary. Although the working surface can remain in the In use position during motion of the vehicle it should be appreciated that use at this time is not intended due to safety Issues.

Figures la - lc illustrates a desk (l) as provided In accordance with a preferred embodiment of the invention. Figures la, lb and lc show perspective, rear and side views of a desk respectively, in various stages of deployment. In Figure la the desk is Illustrated In a deployed arrangement, 300 ready to be used in a vehicle, In Figure lb the desk is shown partially transformed between deployed and storage configurations, and Figure 2c shows the desk in its storage configuration.

As illustrated by the drawings, the desk provides a substantially flat work surface (2) formed from at least two pivotably connected work sections (3),

305 able to rotate on a first plane towards each other. Each work section preferably has a lip extending upwards from the work surface, arranged around the perimeter of each section to retain spilt food or liquids. The desk (1) also includes a support leg (4) which Is pivotably connected to the work sections (3) in a perpendicular plane to that which the work sections rotate

310 on. As can be seen in Figure la, when deployed, the two work sections are rotated from the main body to form a substantially flat work surface (2) and the support leg (4) is pivoted on a perpendicular plane from the work sections to form a right angle to the work surface (2) when the desk is In Its in-use configuration. Conversely, when the desk is in its storage

315 configuration as shown in Figure lc, both work surfaces are pivoted to lie to be substantially parallel and the support leg (4) is pivoted to also be substantially parallel to the collapsed work sections (3) of the desk.

In an alternative embodiment (not shown), the support leg (4) may be 320 provided as a discrete part that is removable from the work sections (3).

When the work sections are rotated in relation to each other and form a flat surface, the support leg is attached by engaging a boss or similar such projection within a recess in each work section, to rotatably lock each section and provide structure to the desk. In such an embodiment, when the desk is stored, the support leg is disengaged from each work section and the work sections folded towards each other, providing two discrete and compact components.

In a further alternative embodiment (not shown), the support leg (4) may be permanently attached to a work section (3) In a substantially perpendicular orientation to the substantial, flat surface of the section. In such an embodiment, the work sections may also be. rotated towards and away from each other to deploy and store the desk, wherein when rotated so that the work section forms a substantially flat surface, a side surface of each work section rests on an adjacent surface of the other section to provide the necessary structural support for the desk.

In any of these embodiments at least one of the work sections (3) may include a cup holder (not shown), being a recessed portion or an aperture having radially extending deformable flaps to retain a beverage bottle or cup within the aperture.

Also as shown with respect to Figures lb and lc a padded region (9) is provided to the underside of each work section (3). The padding improves the comfort of a user employing the desk disposed directly on their lap. This can also provide thermal insulation from hot articles such as food or laptop computers placed on the upper surface of the desk.

The desk (1) is preferably coated, or at least a region of the work surface (2) with a non-slip material such as an elastomer or rubber compound. The desk (1) also includes a pair of locking means (5) as shown in Figures lb and lc. In the embodiments shown, each of the locking means (5) Is formed from a bar or tab which is located within a channel which runs across the undersides of both the work sections (3) shown. This tab or bar can be slid along the channel provided to fix the rotational position of each work section In relation to the central body and support leg (4), shown in Figure lb, locking the work sections In a deployed configuration.

Figures la - lb also show a stabilization structure (6) which includes a ductile or resilient extension bar (7), preferably being a length of copper wire enclosed in a plastic sleeve, and an engagement buckle (8) adapted for insertion into the locking holster of a conventional vehicle seat belt retention mechanism. The buckle (8) can be engaged with the holster of a seat belt and in combination with the extension bar (7), stabilize the table against vibrations or accidental collisions when the desk is in use.

As can be seen from Figure lc the resilient extension bar (7) can be adapted to lie substantially parallel to an adjacent work section when the desk is arranged in the storage configuration shown. In this configuration the engagement buckle (8) and the majority of the extension bar (7) may be disposed or located within a pocket formed within the padded region (9) disposed on the underside of the work section (3).

Figure 2a illustrates a desk (1) in accordance with the previous figures, shown in a deployed state In a vehicle providing a substantially flat work surface (2), whereas Figure 2b shows the same desk in a stored configuration.

In Figure 2a the support leg (4), is pivoted to be substantially perpendicular to the work surface (2) and wedged between the passenger seat and the central console of the vehicle to positively and firmly engage the desk in place. Furthermore, the cylindrical form of the support leg (4) allows the entire work surface to be rotated towards the occupant of the driver's seat if required. The support leg (4) may also be rotatably connected to the work surface (2) to assist rotation of the surface. Figure 2b shows the desk in a storage configuration having the support leg (4) arranged to be substantially parallel to the collapsed work sections (3) where due to the substantially flat profile of the desk, the desk can be stored between the central console and passenger seat of the vehicle.

Figures 3a - 3c show an alternative preferred embodiment of the invention, having a flat work surface (2), being a single work section (3), and an alternative support leg arrangement, being a telescopic leg (10) plvotally connected to the work section such that the leg (10) is rotatable to be substantially perpendicular to the work surface (2). Preferably, the pivot between the leg (10) and the work section (3) is arranged adjacent to an edge of the section and substantially on an axis of symmetry of the section, providing balanced support to the work section and optimising the usable space underneath the work surface.

Figure 3c shows an exploded view of the embodiment, illustrating the components of the telescopic leg (10). The leg is formed from at least two and preferably three tubular sections, labelled as 101-103, which may slide within one another to extend or retract the leg, allowing the height of the work surface (2) to be adjusted in relation to the seats or other interior features of the vehicle. The leg also includes a deformable actuator (104) fixed within a housing in the work section (3) which when depressed by a user, allows the sections of the leg to slide within each other and when released, locks the sections such that the length of the leg may not be further adjusted. The locking function is preferably provided by at least one boss arranged on the actuator, fitting within at least one aperture, arranged within a section.

In Figure 4 an alternative aspect of the invention is illustrated, having an additional support leg, being an extension leg (11). At least one extension leg Is arranged on the underside of the work section (3) and pivotally connected, such that each leg can be rotated to be substantially perpendicular to the work surface (2) and provide additional support to the support leg (4) or telescopic leg (10). The extension leg Is preferably arranged in a corner of the underside of the work section to provide support in regions which may deflect the most when in use, however its location is not limited to this and it may be positioned at any position on the surface. The extension leg is also able to be adjusted in length having an inner section that slides within an outer section, in order to optimise the contact of the leg with a component of the interior of the vehicle. Figure 5 shows an underside view of the desk configured for storage, illustrating the telescopic leg (10) and the extension leg (11) folded towards the work surface (2) and being substantially parallel with it.

Figure 6a - 6b show perspective views of the desk configured for use in a vehicle, having both the telescopic leg (10) and extension leg (11) pivoted, away from the work surface (2) to be substantially perpendicular with the surface. Figure 6a illustrates a first configuration where both legs (10, 11) are configured to be at the shortest length possible for each and Figure 6b illustrates an alternative configuration where both legs are configured to be at an extended position.

Figure 7 illustrates a further alternative embodiment having an extendable strap (12) arranged across the work surface (2) to retain items, such as documents, to the work surface of the desk. The strap Is adjustable in length and preferably in two parts, each part being releasably fixed to the other. Preferably each part of the strap has a hook and loop fastening system, such as Veicro® portion to enable rapid attachment and release of the strap over the working surface of the desk.
