Teacher Demonstration Desk
Abstract
A desk is disclosed for use by teachers. The desk has a
fixed-height portion which remains stationary as well as an
adjustable-height portion which can be raised and lowered as needed
to allow students to view objects on the desk such as experiments
being performed when the adjustable-height portion is in a raised
position and to see the space behind the desk, which may contain a
blackboard, white board, or other object which students would wan
to view, when the adjustable-height portion is in a lowered
position.

Description
FIELD OF THE INVENTION
[0001] The present invention relates generally to desks for
teachers for use in classrooms.
BACKGROUND OF THE INVENTION
[0002] In current classroom environments, teachers' desks can pose
a problem in the classroom. If a teacher's desk is low, it can be
impractical for a teacher to use the desk to perform laboratory
experiments, as students cannot see the experiment being performed.
Additionaly, a low teacher's desk takes up space in a room, so low
teachers' desks which are not usable for experiments must
frequently be put in a corner of a classroom or in another room to
make room for laboratory tables, one of which the teacher must use.
On the other hand, if a teacher's desk is high, such as a
laboratory table used as a teacher's desk, it can block students'
view of things behind the desk. Frequently, a classroom will be
oriented such that a blackboard, white board, projection screen, or
other important piece of classroom equipment will be placed behind
a teacher's desk which the students will need to see. A high
teacher's desk can impede visibility of that piece of equipment for
the students in a classroom. Ideally, a teacher's desk will be
usable both for demonstrating experiments and for performing a
teacher's other work without consistently impeding the view of the
wall behind the desk.
SUMMARY OF THE INVENTION
[0003] We disclose a desk for use in classroom environments. The
desk has a base, an adjustable-height desk surface in the middle
which may be raised and lowered, and a fixed-height surface on one
or both sides for use with parts of the desk that should remain
stationary, such as a sink. The desk has three telescoping legs
attached to the adjustable-height desk surface that serve to raise
and lower the surface as necessary allowing for demonstration of
experiments when the adjustable-height desk surface is in a raised
position and for viewing of the wall or other things behind the
desk when in a lowered position. A motor, which is attached to the
legs, causes them to be raised or lowered when a signal is sent to
the motor to do so.
[0004] Optionally, the base can house drawers or cabinets. Also,
the adjustable-height desk surface can have receptacles for
receiving laboratory rods for use in performing experiments. The
adjustable-height desk surface or the fixed-height surface or both
can be made of a heat and chemical resistant material to protect
them from bunsen burners and chemical spills. The desk can have a
generally planar or angled face depending on the geometry of the
classroom, where the desk is to be placed, and how much room there
is to accommodate the desk. In a preferred embodiment, the
adjustable-height desk surface is the same height as the
fixed-height surface when it is lowered and higher when it is
raised.
[0005] The desk solves the problem of being usable both for
demonstrating experiments and for performing a teacher's other work
without consistently impeding the view of the wall behind the desk
by having the adjustable-height desk surface which may be easily
raised and lowered as needed to accommodate performing of
experiments or viewing of the area behind the desk.
BRIEF DESCRIPTION OF THE DRAWINGS
[0006] A more complete appreciation of the present invention and
many attendant advantages thereof will be readily understood by
reference to the following detailed description of the invention
when considered in connection with the accompanying drawings.
[0007] In the drawings, FIG. 1 illustrates a front plan view of the
desk.
[0008] FIG. 2 illustrates a right side plan view of the desk.
[0009] FIG. 3 illustrates a left side plan view of the desk.
[0010] FIG. 4 illustrates a back plan view of the desk.
[0011] FIG. 5 illustrates an top plan view of the desk.
[0012] FIG. 6 illustrates an bottom plan view of the desk.
[0013] FIG. 7 illustrates a perspective view of the desk from below
and to the right.
[0014] FIG. 8 illustrates a perspective view of the desk from above
and to the left in one embodiment where the desk is straight.
[0015] FIG. 9 illustrates a perspective view of the desk from above
and to the left in an alternative embodiment where the desk is
curved.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE
INVENTION
[0016] In reference to the drawings, there is shown a desk 1 having
a base 2, an adjustable-height desk surface 3, and one or more
fixed-height surfaces 4. At least three telescoping legs 5 support
the adjustable-height desk surface 3 and are driven by a motor, not
shown. An example of telescoping legs 5 which would work for the
present invention would be those sold by Linak.RTM. under the name
Desklift DL6 being controlled by Linak.RTM. control box CBD4. A
sink 12 is disposed in the fixed-height surface 4 for use in
performing laboratory experiments.
[0017] In a preferred embodiment of the invention, the desk 1 can
have drawers 6 or cabinets 7 disposed in the base for storage. Also
in a preferred embodiment of the invention, the adjustable-height
desk surface 3 can have holes 8 therein for receiving laboratory
rods 9 for use in the performing of laboratory experiments.
[0018] The desk 1 can have a generally-planar face 10 as shown in
FIGS. 1-8 or an angled face 11 as shown in FIG. 9. The curvature of
the desk can depend on the size and orientation of the classroom in
which it is to be used.
[0019] It should be understood that the foregoing represents merely
an exemplary embodiment of the disclosed desk and that various
changes and modifications can be made in the arrangements and
details of construction of the elements described and shown herein
without departing from the spirit and the scope of the present
invention.
