Description
BACKGROUND OF THE INVENTION
I. Field of Invention
This invention relates to an improved office work station and, more
particularly, a secretarial work station.
II. Description of the Prior Art
One of the key considerations in planning office space and office
furniture is the selection and arrangement of efficient work
stations for secretaries. Typically, such work stations comprise a
desk and a projecting side unit. A typewriter sits on the side unit
while dictating equipment and a telephone are usually placed on the
top of the desk. Usually, some additional storage is provided
nearby. When the secretary is typing copy, she generally lays the
copy adjacent the typewriter on the side table or she lays it on
the desk top.
One problem with such an arrangement is that the desk top and the
wing unit frequently become veey highly cluttered. It is not
convenient for the secretary to keep things stored in the adjacent
storage unit since generally she has to get out of her chair in
order to get to it. Frequently, material which she is copying gets
lost in the shuffle. Also, it is often difficult for her to arrange
the material properly for convenient copying.
Small easles or work holders are available for placing on top of
the desk or on top of the side unit to hold the work. However, such
items typically hold the work in only one position. Also, they tend
to merely further clutter the top of the desk or side unit. Thus, a
secretary finds her desk top and side unit top cluttered with such
items as telephone, work stands, dictating equipment and
typewriters as well as stscks of work.
Many years ago, it was popular to provide desks having not only a
horizontal work surface, but also an upper storage unit positioned
above the work surface. This at least provided a means for storing
papers and work without having to leave the desk. Unfortunately,
such units are bulky and clumsy and did not lend themselves to the
type of maneuverability and arrangeability which modern office
planners desire.
SUMMARY OF THE INVENTION
In accordance with the invention, an office work station is
provided by a casing having a top, sides, and open front enclosing
a manuscript tray which is slidable into and out of the casing
through the open front. The tray is movable between a first
position wherein the tray is fully within the casing, a second
position wherein the tray is fully removed from the casing, and a
third position intermediate the first and second positions. The
tray is further pivotal about a horizontal axis to permit arbitrary
positioning of the tray in one or more vertical, horizontal, or
inclined positions.
In other preferred aspects of the invention, the work station
includes a desk module positioned in front of and in abutment with
the casing, the latter having an upper portion in which the
manuscript tray is centrally housed. The storage and retrieval unit
is positioned in one end of the upper portion while a telephonic
unit is positioned in the other end, both ends being separated by
the manuscript tray. Both units are preferably interchangeable so
that the work stations will accommodate right- or left-handed
personnel. A pull-out cover panel is pivotal in its pulled-out
position to cover the open front of the upper casing portion when
the manuscript tray is in the first position so that the entire
casing is enclosed. In yet narrower aspects, the manuscript tray is
positionable in either a horizontal or vertical position in its
first position permitting closure thereof in either a vertical or
horizontal position.
There are several advantages provided by the office work station of
our invention. First of all, the modular aspect of the casing and
desk provides a work station of considerable volume and depth for
storing, retrieving, and performing different work functions, yet
the station can be easily moved to various locations through
conventional doorways since the independent modular aspects of the
invention provide independent movement of the casing and desk
module.
The unique manuscript tray permits complete adjustment by the user
in both the degree of removal of the tray from the casing enclosure
and the angle of incidence at which the tray is positioned. By
being positionable in a vertical orientation fully within the
casing, the work station can be easily closed for example during a
lunch break, with the manuscript being utilized at the particular
time not having to be removed from the tray in order to close the
casing. It is thus immediately available when the station is
reopened.
Additional significant aspects of the invention are the provisions
of basic end units comprising a storage and retrieval unit for
stationery and the like and a telephonic unit on the other end,
these basic units being interchangeable if desired to accommodate a
right- or left-handed person.
The overall combination of these units with a manuscript tray and
desk module presents an extremely attractive, flexible, and
efficient work station having great utility not previously
available in accordance with the teachings of the prior art.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the drawings in detail, an office work station 10
is illustrated in FIG. 1 comprised of front and rear modules 12 and
14. The front module 12 is a desk module having a disk top 16,
upstanding end panels 18, 20 and a file drawer unit 22. The rear
module 14 which is in abutment with desk module 12 includes an
upper case 24 extending well above desk top 16.
Rear module 14 includes a pair of upstanding end panels 26 and 28
which support the entire module. Top case 24 includes a top wall
30, a bottom wall 34, and end walls 35 and is supported between end
panels 26, 28. A work top or shelf panel 32 is supported between
end panels 26 and 28 at a level to coincide with the level of desk
top 16 providing an extremely enlarged work surface combined of
desk top 16 and shelf 32. A pedastal such as drawer unit 22 or
other work unit could be mounted below shelf 32, facing rearwardly
so that another work station on the opposite side of rear module 14
could have access to it.
Wall 34 defines a second shelf or work platform above shelf 32.
Spaced slightly above shelf 34 is a panel 36 which likewise extends
between the end walls 35 of the top case of rear module 14. Panel
36 forms the support base for two modular units referred to as a
storage and retrieval unit 40 comprised of a plurality of
pigeon-holed tray compartments for storing stationary, manuscripts
and other types of supplies and a telephonic unit 42 housing a
communications instrument such as a telephone 44. Upper portion 24
preferably includes a plurality of laterally spaced partitions 46,
48, and 50 which extend from panel 36 up towards top panel 30.
Panels 46 and 50 divide upper portion 24 into a pair of end
sections 52 and 54 and a central section 56. Central section 56
houses a manuscript tray assembly 60, the details of which will be
described hereinafter. Partition 48 along with partition 50 further
defines a book or manuscript storage compartment 62. It will be
appreciated that the spacings of the various partitions are
adjustable as desired in accordance with conventional skills in
this art. Various latching or fastener means are known to
accommodate this and hence not shown or described in detail.
The manuscript tray assembly 60 is adapted for positioning in
several different positions wherein the manuscript tray 64 can be
pulled out of central section 56 over desk top 16 at any angle of
inclination between a horizontal position such as that illustrated
in FIG. 3 to a position at an angle of incline such as that
illustrated in FIG. 1. In either of these or other adjusted
positions, the degree of removement from section 56 can be varied
as desired.
The storage and retrieval unit 40 shown in end section 52 and
telephonic unit 42 shown in end section 54 are removable and
interchangeable so that work station 10 can be adapted for right or
left-handed personnel. The details of this will be described
hereinafter although reference is made to FIG. 2 wherein the
storage and retrieval unit 40 is shown partially removed which
position would not be maintained during normal use of the work
station.
With the manuscript tray 64 positioned in the horizontal position
illustrated in FIG. 2 and completely pushed within central section
56, the upper case 24 of rear module 14 can be enclosed by a cover
panel 70 which is normally stored in a horizontal recessed position
immediately beneath top panel 30. Cover panel 70 is anchored to
rear module 14 on a conventional trackway which permits the cover
to be pulled completely out of upper case 24 and pivoted about a
horizontal axis into a vertical position as illustrated in FIG. 4
completely enclosing the work and storage units housed within upper
case 24.
Referring now in detail to FIG. 5, manuscript tray assembly 60 is
illustrated in more detail having a tray 64 with a lip portion 66
formed by reverse bending along its lower periphery defining a
support for a manuscript or the like. Tray 64 is supported by a
generally U-shaped rod-like support bracket 68 comprising a pair of
arms 72 and 74 (FIG. 3) interconnected by a base portion 76. Tray
64 is pivotally connected to base 76 by a pair of hinge elements 80
to be described hereinafter. Arms 72 and 74 are slideably connected
respectively to the underside of shelf 120. The attachment of arm
72 to shelf 120 is illustrated in FIG. 5 and since the attachment
of arm 74 to shelf 120 is similar thereto, it will not be described
in detail.
An L-shaped bracket 82 (FIG. 6) is welded or otherwise secured to
shelf 120 and an elongated cylindrical tube 84 is in turn welded or
otherwise secured to the vertical arm 86 of bracket 82. The inner
diameter of tube 84 exceeds the diameter of arm 72, the latter
being slideably supported within tube 84 by a pair of plastic
bushings 88 snugly fitted within tube 84. Bushings 88 have an inner
diameter corresponding essentially to the diameter of the rod-like
arm 72 but frictionally engaging same so that arm 72 is slideable
relative bushings 88 but frictionally kept in the desired position
to prevent unintentional sliding movement. The longitudinal
extension of arms 72, 74 in the direction of arrow A (FIG. 5) is
thus easily adjusted between the inwardmost position illustrated in
FIG. 5 for storing the manuscript tray within upper case 24 to a
fully extended position illustrated in FIG. 3 wherein tray 64 can
be pivoted into any desired position of incline, one of which is
illustrated in FIG. 1.
Referring back to FIG. 5 in detail, the pivotal rotation of tray 64
about base 76 is provided by a pair of spaced hinge assemblies 80
which pivotally attach tray 64 to base rod 76. Each hinge assembly
80 is formed of a pair of mating hinge elements 90 and 92
interconnected to each other for frictionally encapsulating a
portion of base rod 76 to permit rotation thereabout, the friction
engagement keeping the tray at the desired position. The hinge
element 90 includes a flat backing plate 94 (FIGS. 5 and 7) and a
sloped protruding portion 96 which terminates to an apex 98. A
groove 100 is formed at the apex, groove 100 having a radius
approximating the radius of base rod portion 76 and a surrounding
bearing member 76a, the latter seating in groove 100. A threaded
opening 102 (FIG. 7) is also formed in protruding portion 96 as is
a relatively narrow rectangular slot 104. Bearing 76a is a plastic
sleeve.
Hinge element 92 is a steel clip formed into a shape forming a
groove portion 106 matching groove 100 with a generally radial arm
portion 108 having an opening for receipt of a threaded fastener
110 which fits through wing 108 and into threaded opening 102 on
the hinge element 90 to secure clip 92 to element 90. A second
radial wing 112 extends generally opposite wing 108 and has a
L-shaped finger portion 114 at the outer end which through rotation
is inserted into rectangular slot 104. The insertion of finger 114
into slot 104 proceeds the fastening of threaded fastener 110. The
degree of friction engagement can be adjusted by tightening
threaded fastener 110 so that unintentional rotation of tray 64
will not occur.
Referring briefly back to FIG. 2, shelf 120 is illustrated within
central section 56 of upper case 24. This shelf is extremely useful
when the manuscript tray 60 is in the horizontal fully inserted
stored position as illustrated in FIG. 2. Shelf 120 is likewise
illustrated in FIGS. 3, 5, and 6 and it will be appreciated that
when the manuscript tray is in the stored position, it must be
completely pulled out before the inner margin 122 will clear the
outer margin 124 of shelf 120 so that tray 64 can be pivoted to a
selected angle of incline. After the angle of incline is selected,
however, the tray can be repositioned inwardly if desired depending
on the angle of incline. There is an inwardmost position wherein
the underside of tray 64 will come into abutment with the outer
margin 124 (FIG. 5) of shelf 120 depending on the angle of incline.
At the innermost position, however, tray 64 can be positioned in a
vertical orientation as illustrated in FIG. 5. In this position,
the tray is positioned within central section 56 to permit closing
of cover panel 70 into the position illustrated in FIG. 4. This
added feature allows a user to be working at the work station
utilizing the manuscript tray and if desired to close the work
station for a period of time without collapsing the tray into the
horizontal storage position illustrated in FIG. 2. Instead, the
tray can simply be pushed into central section 56 with the tray
moving into the vertical orientation illustrated in FIG. 5 so that
the entire manuscript tray is immediately available for reference
when the office work station is reopened.
Shelf 120 is preferably welded to and supported by the horizontal
leg 87 (FIG. 6) of L-shaped bracket 82 and the similar bracket
secured to partition 48 (not shown). The vertical leg 86 is
fastened by screws to partition 46 (or 48). A plurality of screw
holes are provided inpartitions 46 and 48, same at each of several
different levels so that shelf 120 can be raised higher or lower,
thereby changing the height of manuscript tray 60.
Referring now to FIG. 2, the storage and retrieval unit 40 is
illustrated partially removed from end section 52 of upper case 24.
The particular unit 40 illustrated is comprised of a lower unit 40a
and an upper unit 40b both of which are modular and can be
independently inserted and removed from end section 52. The
particular configuration with regard to the number of tray elements
45, etc., can vary according to need. The removability, however,
adds extra flexibility to the overall work station permitting
replacement by modified units or interchangeability with telephonic
unit 42 which can be removed from end section 54 to make the
telephonic aspect of the work station right or left-handed.
Referring now in detail to FIG. 8, the configuration of telephonic
unit 42 is illustrated. A support bracket 130 is removably attached
to partition 50 by a pair of threaded fasteners 131. A plurality of
openings 133 are provided for receipt of fasteners 131 so that the
position of bracket 130 depthwise within end section 50 can be
adjusted. The reason for such an adjustment is that telephonic
units vary slightly dimensionally one from the other depending on
the particular make and manufacturer.
Support bracket 130 includes an inwardly projecting flange 132
which along with support bracket 130 is positioned on an angle of
incline. The angle of incline depends on the corresponding desired
angle of inclination of the telephone itself. Support bracket 130
extends to the floor of the unit which is defined by shelf 36 when
the telephonic unit is in position. The upper margin 134 includes a
plurality of notches 136 forming spaced keeper teeth 138a, 138b,
and 138c. It will be appreciated that a bracket identical to
support bracket 130 is affixed to the wall portion opposite
partition 50 of the particular end section utilized with a matching
inwardly facing flange with keeper notches. The two support
brackets along with their respective flanges provide a seat against
which a conventional telephonic unit of given origin (not shown) is
positioned and indexed.
After the particular telephonic unit is inserted and appropriately
attached to the flanges 132 of support brackets 130, a bezel
bracket 140 is anchored to bottom shelf 36. Bottom shelf 36
includes an opening 142 while bezel bracket 140 includes an opening
144, at least one of the openings being slot like to provide
longitudinal adjustment of bracket 140 relative bottom shelf 36
depending on the depth of the telephonic unit. Bracket 140 includes
a generally upstanding portion 146 and a keeper portion 148 which
includes a downwardly depending finger 150. The front of the
telephonic unit is enclosed by a bezel plate 152 which forms a
frame over the telephonic unit having appropriate openings to
permit projection of the dialing apparatus and telephone ear and
mouthpiece. Bezel plate 152 includes an upwardly turned lower
margin 154 terminating in an outer lip 156 which is pivoted behind
keeper 148 of bracket 140. The configuration of lower margin 154 is
that of a trough whereby secretarial utensils such as pencils, pens
or erasures, etc., can be conveniently stored in the trough portion
formed by bezel plate 152. The upper margin 158 is formed inwardly
and includes an inturned lip 160 forming a catch which can be
inserted over the top of support bracket 130 to catch one of the
teeth 138, 138b and 138c. The desired keeper for locking depends
again on the longitudinal depth of the particular telephonic unit.
Thus, a completely removable telephonic unit is provided which is
flexible to house one of several conventional telephonic units
which vary dimensionally by manufacturer. The removability permits
positioning of the telephonic unit in either end section 50 or 52
to accommodate a right- or left-handed user.
Although but one embodiment has been shown and described in detail,
it will be obvious to those having ordinary skill in this art that
the details of construction of this particular embodiment may be
modified in a great many ways without departing from the unique
concepts presented. It is therefore intended that the invention is
limited only by the scope of the appended claims rather than by
particular details of construction shown, except as specifically
stated in the claims.
