[0001] The present invention relates to a desk, particularly intended as workplace for a
user of a computer system with data input means and/or cursor control means, which
desk is provided with a work surface for placing of at least the data input means
and/or the cursor control means.
[0002] Such a computer desk is known in the field. A good deal of attention is paid nowadays
to preventing symptoms caused by Repetitive Strain Injury (R.S.I.), also known as
"mouse-arm" among computer users. This is possible for instance by adding accessories
to the computer desk, such as by placing a wrist support in front of the keyboard
or integrated into the mouse mat. In a completely different approach, different assist
means are attached to the computer desk, for instance adjustable supports for placing
of the keyboard or the monitor. A proviso for successful use of these assist means
however is that they are optimally adjusted to the individual user. This is generally
a time-consuming activity, wherein some knowledge of ergonomics is required. It is
therefore often found in practice that the assist means are not used in the correct
manner, especially when a workplace is used by turns by different users.
[0003] The invention has for its object to provide a desk of the type stated in the preamble
which obviates this drawback.
[0004] For this purpose the desk according to the invention has the feature that the work
surface comprises one or more recesses for receiving the data input means and/or the
cursor control means.
[0005] The desk according to the invention has the advantage that the data input means,
such as the keyboard, and/or the cursor control means, such as the mouse, will automatically
be in the correct position during use, this being indicated by the recesses. Furthermore,
the data input means and/or the cursor control means are automatically received in
the work surface in slightly recessed manner owing to the depth of the recesses. This
has the immediate consequence that the forearms of the user are supported as much
as possible by the work surface. Excessive strain on shoulders, arms and wrists with
repetitive movements is thus prevented. The chance of symptoms such as R.S.I. occurring
hereby decreases considerably.
[0006] In a first preferred embodiment the depth of the recesses is adapted to the height
of the data input means and/or the cursor control means such that the forearm(s) and
hand(s) of the user lie as much as possible in one line while working with the data
input means and/or cursor control means. The user hereby assumes a natural position.
The depth of the recesses is preferably substantially equal to or larger than the
height of the cursor control means and/or the data input means. The user hereby adopts
an ergonomically safe posture, in which the hands as it were drop onto the cursor
control means and/or the data input means without the user having to hold them unawares
in an unnatural position directed slightly upward.
[0007] In a practical preferred embodiment of the invention the work surface comprises a
recess for receiving a keyboard and/or a mouse. The work surface preferably comprises
two recesses for receiving a mouse which are situated on either side of the recess
for the keyboard.
[0008] In an elegant embodiment the work surface comprises one recess which is provided
in the centre with a deepened portion for receiving the keyboard, wherein on either
side of the central deepened portion are situated two further deepened portions in
slightly higher position for receiving the mouse. A uniform desk is hereby created
which is suitable for both left-handed and right-handed users.
[0009] According to a further preferred embodiment the dimensions of the recesses in longitudinal
direction are greater than the corresponding dimensions of the data input means and/or
cursor control means for receiving therein such that the workplace can be adjusted
to the individual user by displacing the data input means and/or the cursor control
means in the respective recesses. The desk according to the invention is thereby optimally
adjustable for any user in simple manner.
[0010] According to another preferred embodiment, there is provided a set of mats for receiving
in the recesses, wherein the dimensions of the mats in length and width direction
are substantially equal to the corresponding dimensions of the respective recesses.
Undesired shifting of the data input means and/or the cursor control means out of
position is prevented by using the mats.
[0011] The set of mats preferably comprises mats of different height. The data input means
and/or the cursor control means can now be adjusted to the correct height in simple
manner. The set of mats preferably comprises one or more mouse mats.
[0012] According to a further preferred embodiment the work surface comprises a further
recess for receiving a monitor and/or a further recess for receiving one or more sheets
of text. When these embodiments are used the head and neck of the user also automatically
assume a correct posture.
[0013] The invention also relates to a work surface as described as part of a desk according
to the invention.
[0014] The invention will now be discussed in more detail with reference to the drawings,
in which
Figure 1 shows a schematic three-dimensional view of an office furnishing, of which
the desk according to the invention forms part;
Figure 2 shows a schematic three-dimensional view of the desk of figure 1 in more
detail; and
Figure 3 is a schematic three-dimensional view of the desk of figure 2 fitted as workplace
with computer and office materials.
[0015] Figure 1 shows a schematic three-dimensional view of an office furnishing 1. Office
furnishing 1 comprises two tables 2 which are placed in an angular arrangement. Computer
desk 3 according to the invention is arranged in the angle. The desk further comprises
a support frame, of which only legs 10 are shown schematically.
[0016] Figure 2 shows computer desk 3 in more detail. Desk 3 has a work surface 4 which
is provided with different recesses for components of a computer system and for office
materials. There is a recess 7 for receiving data input means, such as a keyboard,
and cursor control means such as a mouse. Recess 7 consists of a central deepened
portion 5 for the keyboard. On either side of the central deepened portion 5 are situated
further deepened portions 6 for receiving a mouse.
[0017] A recess 8 is provided for receiving sheets of text. Recess 8 has an inclining surface,
so that the text lies at an angle such that the user assumes an ergonomically safe
posture of his or her head during reading of the text. This preferably lies at between
20 and 50 degrees and more preferably approximately 30 degrees. Adjusting means are
preferably provided in recess 8 for adjusting the relevant angle, for instance in
the form of a tiltable insert for the sheets of text.
[0018] The position of recess 8 is advantageously chosen between recess 5 for the keyboard
and recess 9 for the monitor. The field of view of the user can be moved from the
monitor to the text, and optionally to the keyboard or the mouse, with minimal head
movements. The optimal position for the monitor in recess 9 is at arm's length from
the user.
[0019] For the purpose of illustration figure 3 finally shows work surface 4 adapted as
workplace with the above mentioned computer components and office materials. A keyboard
11 is received in recess 5. A mouse 12 lies on a mouse mat 13 in right-hand recess
6. The left-hand recess 6 is used in this example for placing of a document file 14.
Sheets of text 15 lie in recess 8. The foot of monitor 16 is placed in recess 9.
[0020] The correct position of keyboard 11 is simple to adjust by shifting the keyboard
in longitudinal direction, i.e. away from or toward the user, depending on the length
of his or her arms. For this purpose the dimensions of recess 5 in longitudinal direction
are greater than the dimensions of keyboard 11 in longitudinal direction.
[0021] In order to prevent undesired shifting out of position, one or more mats are provided
for recesses 5, 6 and 7 (not shown). A set of mats of different height is preferably
provided. Through a correct choice of the mat height the computer desk according to
the invention can be adjusted to the individual user as an ergonomically safe workplace.
[0022] Means are preferably arranged in recess 9 for height adjustment of monitor 16. Such
a height adjustment can be realized in many ways, and comprises for instance a carrier
which is height-adjustable in mechanical, electrical or hydraulic manner.

the shown and described embodiment, but extends generally to any embodiment which
