The invention relates generally to adjustable work surfaces. More particularly, the invention relates to an adjustable work surface support mechanism for mounting a secondary work surface to a primary work surface.
BACKGROUND OF THE INVENTIONIn the field of traditional support mechanisms, there are many different types of adjustable work surface support mechanisms. However, such support mechanisms generally require a large number of individual parts, making it expensive to manufacture and difficult to assemble.
There are other support mechanisms which are used in workplace desking. These support mechanisms provide support for adjustable secondary work surfaces to be manually moved from a first position to a second position in the vertical direction with respect to a primary work surface. However, virtually all “keyboard arms” have an inherent limit of vertical adjustability to 3 to 4″ in relation to a static primary work surface.
In addition, many of these support mechanisms include parts underneath the secondary work surface which, by their construction, can cause injury when a user's legs coming into contact against it or a user's hands when they try to adjust the height of the secondary work surface.
It is, therefore, desirable to provide an adjustable work surface support which overcomes some of the problems of the prior art.
SUMMARY OF THE INVENTIONIn one aspect, there is provided a work surface support mechanism which is connected at one end to a primary work surface and a second end to a secondary work surface. In use, the mechanism provides assistance in adjusting the height of the secondary work surface with respect to the primary work surface so that the secondary work surface is in an ergonomic position for the many users that may use the workstation. Further, when the secondary work surface is not required, the mechanism can be stored underneath the primary work surface and is out of the way of the user.
Further, the current invention can support a true “Secondary Surface” well beyond keyboard platforms, and hence has the flexibility to support many other workplace applications.
In the preferred embodiment, tubular arm components are employed which provide for “soft contact” with the users legs.
Therefore, there is provided a novel mechanism for work surfaces which combine a plurality of operational characteristics such as but not limited to (1) vertical adjustability; (2) tubular component construction for “soft contact”; or (3) retractability from the work area when not required.
Embodiments of the present invention will now be described, by way of example only, with reference to the attached Figures, wherein:
The work surface mechanism 10 is typically in two positions, which can be seen as an in storage position (
Turning to
The mechanism 10 further includes a pair of tubular arms 14a and 14b, each arm 14a and 14b connected at one end to an associated mounting bracket 16. The mounting brackets 16 are used to mount the mechanism 10 to the secondary work surface 102, such as a keyboard platform, which can then be height-adjusted, according to the particular user's physical attributes. This secondary work surface 102 is typically platform sized and suitable for the designated activity.
The other end of each arm 14a and 14b is connected to a bar 18, extending through the main body 12. The bar 18 acts as a pivot point so that the arms 14a and 14b can move in a vertical direction with respect to the main body 12, allowing the height of the secondary work surface 102 to be adjusted with respect to the primary work surface 100. As indicated above, the mechanism 10 is preferably mounted to the track system 104 (mounted under the primary work surface 100) so that the secondary work surface 102 can be stored underneath the primary work surface 100 when not in use (
When the mechanism is the in use position (
A follower arm 22 is located adjacent one of the arms 14b to provide further support to the mechanism 10 and to maintain the parallelism between the two work surfaces 100 and 102.
The mechanism 10 further includes a tilting mechanism 24 which is activated by a knob 26. The tilting mechanism 24, or apparatus, allows the secondary work surface 102 to be tilted, with respect to the primary work surface 100 in case the user wishes to place the work surface 102 in a more ergonomic position. For example, if the secondary work surface platform is supporting a computer keyboard, the user may wish to tilt the platform towards themselves to reduce the strain on their wrists.
Due to the mechanics and properties of the work surface mechanism 10, an advantage is that the mechanism 10, in one position, allows the secondary work surface 102 to be stored completed underneath the primary work surface 100 when the secondary work surface 102 is not needed. When the secondary work surface 102 is required, the mechanism 10 allows the secondary work surface 102 to be slid out to an operational position and the height of the work surface 102 can be adjusted to suit the user's height to provide a more ergonomically comfortable work attitude.
One advantage of the invention is that this unit has a vertical range of up to 12″, which is an improvement over current “keyboard arms”.
The above-described embodiments of the invention are intended as examples only. Alterations, modifications and variations may be effected to the particular embodiments by those of skill in the art without departing from the scope of the invention, which is defined solely by the claims appended hereto.
