TECHNICAL FIELD
[0002] This invention relates to a computer support system
attachable to a chair or desk and that allows the user seated in a
chair to comfortably operate a standard computer keyboard/mouse pad
or other electronic devices. The system is also removable from the
chair or desk to provide support in a lap use environment.
BACKGROUND OF THE INVENTION
[0003] Traditionally, computer components are arranged on a
desktop. The computer keyboard rests on the desk in front of the
computer monitor. Alternatively, some computer desks include
special keyboard locations, such as retractable surface. The
retractable surfaces are mounted to the desktop's undersurface.
Usually, this under-mounted support surface slides in and out on a
set of guides/tracks/channels/slots.
[0004] Another method of supporting a keyboard includes a support
surface mounted with a single a single arm generally located in the
center of the desk but sometimes offset from the center. These
permanently attached under-mount systems are popular with the
computer users.
[0005] With the advent of wireless computer keyboards and mice, a
need has developed for a mobile or portable support surface for
these items. Although these wireless components/devices are
portable, the traditional desk or slide-out under-mounted support
surfaces are not. This leaves the user limited options on how and
where to rest these components.
[0006] Take for example the resting place options for a mobile
laptop computer: Laptops are generally supported on a desktop or
other type of permanent surface, in the user's hands, in the user's
lap, or balanced across the user's knees. The posture required to
use a laptop supported in these ways is often uncomfortable and
unnatural. Furthermore, outside of the mini-mouse pad provided on
laptops, no solid support surface is provided for the use of the
traditional full-sized mouse, which is still preferred used along
side a laptop computer.
[0007] The present invention is provided to solve the problems
discussed above and other problems, and to provide advantages and
aspects not provided by prior desk systems. A full discussion of
the features and advantages of the present invention is deferred to
the following detailed description, which proceeds with reference
to the accompanying drawings.

DETAILED DESCRIPTION
[0078] While this invention is susceptible of embodiment in many
different forms, there is shown in the drawings and will herein be
described in detail preferred embodiments of the invention with the
understanding that the present disclosure is to be considered as an
exemplification of the principles of the invention and is not
intended to limit the broad aspect of the invention to the
embodiments illustrated.
[0079] The present invention is directed to a computer
support/workstation and system with two specific use positions. The
first use position includes a support frame and top support mounted
to a chair. This portion of the invention allows the chair occupant
a great range of body motion and movement while maintaining close
contact with a computer keyboard, mouse pad, laptop or the like.
The many advantages of having the above component travel with the
chair user, at an arms length away, are numerous and obvious. The
second use position described refers to a top support surface
removed and separated from its chair mounted support frame. This
portion of the invention is as useful, if not more, under certain
circumstances.
[0080] The completely mobile top support surface can be easily
carried across a room or an office over in the hands of the user,
who then would set the support top on a number of surfaces,
including the user's lap. This portability feature allows the user
of a laptop computer or keyboard to add great mobility and
stability, versus attempting to balance the smaller sized foot
print of these components on their knees or lap.
[0081] This portable system also provides an armrest with an area
to operate a mouse and a writing surface with storage below. Once
again, the support top holds the wireless keyboard, mouse, laptop
computer or other component at arm's length for the user, making
its benefits obvious.
[0082] The combination of the two aspects of the present invention,
as stated above and within this document, achieved from the one
single system, makes this system extremely practical to manufacture
and should be desirable to use and to own.
[0083] Accordingly, embodiments of the present invention are
directed to a computer support system. The system allows a user
seated in a chair to comfortably operate a standard computer
keyboard, mouse pad or other electronic devices while adding great
mobility and convenience, not available in traditional
computer/keyboard setups. Once the system is adjusted to suit the
individual user, the relationship between the user and the system
remains the same. The user is able to move freely about a floor
area depending on the style of the chair and the space available,
while maintaining constant access to the keyboard or such
devices.
[0084] These embodiments include, but are not limited to, three
possible applications. First, a chair would come factory equipped
with system included. Secondly, the system could be designed for
office retrofitting a standard office type chair. This would be
accomplished by attaching a wide flat or slightly curved plate to
the under side of the chair seat, which typically consists of
plywood, plastic, metal, or the like. This flat plate is
welded/attached on a 90 degree angle to a vertically telescopic
member. Thirdly, the system could be designed to adapt to the
standard telescopic armrest that is commonly found on a number of
office type chairs. This application could be achieved by removing
the screws that secure the padded upper portion of the armrest to
the remaining portion. The new system would bolt on using existing
holes. The armrest's original up and down adjustment would
eliminate the need for a vertical telescopic member of the system
which would be needed for other retrofit or factory installed
systems.
[0085] Embodiments of the invention described within this document
relates to the use of a computer keyboard, laptop, note pad, DVD
player or other devices, more specifically the support surfaces on
which these items rest.
[0086] An embodiment of the invention provides a solid support
surface for computer devices and office supplies during lap use. In
addition, the lap use support surface could be equipped to portably
mount to the underside of a traditional desk. In essence, this
embodiment is comprised of one single support surface which
transitions portably between a desk mounted use position to a
convenient and comfortable lap use component support surface.
[0087] In one embodiment, a computer support is attachable to an
external body, such as a chair or desk. The computer support
comprises a top support means which includes a first support joined
to a second surface. A first pivoting means provides for at least
partial rotational movement of the top support about a pivot point.
An alignment means is provided for moving at least a portion of the
computer support along a horizontal plane, and a frame means is
provided for attaching the support means to the external body.
[0088] The alignment means may provide for drawing the computer
support in a north to south direction relative to a user.
Alternatively, or in addition to north to south movement, the
alignment means may be provided for bringing the surface into
substantial parallel alignment with the second surface (e.g.,
relative rotational movement aligns the two surfaces in
parallel).
[0089] The pivoting means may be a hinge or pin/guide (as in a
track, slot, or channel) arrangement.
[0090] In the pin/guide arrangement, the pin joins the first
surface to the second surface. The pin is located within the guide
and is capable of rotating and traversing within the guide. The
alignment means may include a second pin and a curvilinear guide
wherein the second pin is located within curvilinear guide and
traverses therein. This alignment means selectively brings the
first surface and the second surface into substantially vertical
alignment.
[0091] In another embodiment, a computer support provides a
variable workspace for a user. The computer support comprises a
first surface positioned along a first substantially horizontal
plane, a second surface offset from and located on a separate
horizontal plane than the first surface; and a pin joining the
first surface and the second surface. The pin defines a pivot point
upon which the first surface is pivotally mounted to the second
surface for rotational movement about Lie pivot point along the
first substantially horizontal plane. A guide is adapted for
receiving a portion of the pin. At least one portion of the guide
is in substantial alignment with the second surface, and the pin is
adapted for traversing the at least one portion of the guide. This
embodiment may also include a mounting system for attaching the
computer support to a chair. The mounting system may include a
first bracket attached to the second surface, and a second bracket
having a first portion attached to the first bracket and a second
portion for attachment to a chair. The mounting system may include
a frame attachable to the first bracket. The frame provides
structural support for the first and second surfaces. Accordingly,
the frame includes a first member located beneath the first surface
and a second member generally transverse to the first member and
located beneath the second surface. This embodiment may further
include a second pin and a curvilinear guide. The second pin joins
first surface and said second surface. The curvilinear guide is
adapted for receiving the second pin wherein the second pin
traverses within the curvilinear guide.
[0092] Yet another embodiment of the present invention provides a
computer support system for selective attachment to an external
body, such as a desk or a chair. The computer support system
comprises a top support comprising a first surface and a second
surface. The first surface is located on a separate horizontal
plane than the second surface. A first pin joins the first surface
with the second surface. The first pin defines a first pivot point
upon which relative rotational movement between the first surface
and the second surface bring the first surface and the second
surface into selective substantially parallel alignment. A second
guide extends along a portion of the top support. The pin is also
located within the second guide wherein traverse of the first pin
within the second guide brings the first surface into selective
substantially vertical alignment with the second surface. A second
pin is located between the first surface and the second surface. A
third guide has a curvilinear shape. The second pin is adapted to
traverse along a length of the third guide. The first surface may
be selectively rotated about the pivot point and traversed in a
plurality of directions.
[0093] The various embodiments will become more clear with
reference to the Figures as set forth below.
[0094] FIGS. 1-3 are illustrations of a computer support system or
support system 10 ("the system") of the present invention. The
system 10 is illustrated in use with, as in attached to, a chair
11. It is contemplated that the system 10 may be supplied with, as
permanently attached to, or retrofit, as in selectively attached
to, an office chair 11 or the like. As will be described in more
detail below, the system 10 can be separately removed from the
chair 11 for use in other relaxing positions.
[0095] The system 10 is adapted for arranging a computer mouse,
keyboard, laptops, or other personal electronic devices. The system
includes a top support 14 comprising a pair of surfaces 16, 18
having hinges 20, 21 for clockwise or counterclockwise rotation
about the hinges 20, 21. Accordingly, the surfaces 16, 18 may be
lifted and a storage area 22, designed to accommodate recessed
trays for pens, pencils, compact discs. etc. may be located under
surfaces 16, 18. The top support 14 may also be pivoted about a
hinge 21 to facilitate entry or exit from the chair 11. The
movement is indicated by an arrow on FIG. 2. The top surface 14
also includes an alignment means that allows north to south (or in,
towards a user, and out, away from a user) movement of the top
surface 14. This movement is indicated by an arrow on FIG. 1.
[0096] Additionally, surfaces 16, 18 may slide out to accept other
size devices, laptops etc. An under support surface area could also
accommodate a. pull out drawer. This auxiliary support
surface/drawer could also act as an area to rest one's wrists while
operating the keyboard. A slide out surface to accept mouse pad for
left handed users may also be included.
[0097] The system may include an under seat mounted side saddlebag.
This storage area could be used in conjunction with the system 10.
It would make for convenient storage of the keyboard, laptop,
schoolbooks, etc.
[0098] It should be understood that the top support 14 can be many
shapes and sizes to accomplish its task, and the invention
primarily lies in its workings than its appearance. Furthermore, it
is also understood that the above mentioned top support 14 could
also be used not only to support other devices, but as a convenient
working and writing area, using traditional means for writing or
the new electronic type computer pens.
[0099] The system 10 is capable of movement in many directions to
accommodate comfort of the user, preferably one of the movements
includes a north to south motion to move the top support 14 closer
to or farther away from a user. FIG. 3 shows a side view of a third
position with the top support 14 opened for access to the storage
within. On some models this hinged storage feature may be excluded.
Furthermore, other systems (models) may include storage in the
second surface/armrest 18 only. This would allow on some models the
support surface which holds the keyboard or devices to telescope or
fold next to or into the armrest 18, mouse pad support area.
[0100] Referring to FIG. 3. several arrows illustrate various
movements of the system 10. The system 20 may tilt or pivot about
hinge 21, allowing for comfortable chair entering and exit. The
mouse pad and keyboard could be secured to the first surface 16
using a number of commonly available attachment means, for example,
Velcro, suction cup, adjustable clamps, sliding clamps, etc., or
would rest against a raised edge on the first and second surfaces
16, 18. The top support 14 also moves in a north to south
orientation for the comfort of the user.
[0101] FIG. 4 is a perspective view of the system 10 showing
various directional movements illustrated with arrows. A first
telescopic subsystem 26 allows up and down vertical movement. The
telescopic subsystem 26 may include rectangular members lengthwise
with the armrest 18 to achieve more strength to the keyboard or the
like. A receiving member (outer) 26a may also include a reverse
spring to aid in the raising up of the system 10. Furthermore, this
vertical telescopic member 26a may also consist of a pneumatic lift
similar to the type found on adjustable swivel chairs.
[0102] A second telescopic subsystem 28 allows the system 10 to
forward and backward in a substantially horizontal motion along a
horizontal plane away and towards a user seated in the chair. This
subsystem 28 allows for north and south adjustment in relationship
to a seated user.
[0103] As illustrated in FIG. 4, the top surface 14 is supported by
transverse support members 30, 32 which are pivotally mounted. A
mounting 33 for attachment to a chair is attached to the first
telescopic subsystem 26.
[0104] Options for mounting the surface 18 are illustrated in FIGS.
5-8. FIG. 5 is an illustration of a third telescopic subsystem 29
for lateral movement of the system 10, as in
right-to-left/left-to-right movement. FIG. 6 illustrates a pivoting
system about pivot joint 34. FIGS. 7 and 7a illustrate a swing arm
support system 36. Also, this embodiment includes a bendable swing
arm system 38 with a disk suction cup 40 as a means to attach
keyboard or other devices. The suction cup 40 would be similar to
the type used in the window glass and/or car dent puller industry.
This swing arm/suction cup would fold and store into the offset
(raised) armrest. Detail of a typical swing arm connection is
illustrated in FIG. 7a. FIG. 8 illustrates a variation of a swing
arm 42 and suction cup 40 or other attachable means disk.
[0105] FIG. 9 shows a first surface 16 and a portion of a second
surface 18. This arrangement may include a hinged offset 44 which
allows mouse pad surface to be higher in relationship to the
keyboard. This offset 44 also forms curb to hold keyboard during
tilt position. The offset or raised edge 44 allows the mouse, and
keyboard to remain on the surface 16 as it is tilted. The position
of this hinge 44 allows the keyboard surface 16 to tilt up for
chair entry, while the mouse pad/armrest remains in its standard
first use position.
[0106] An optional hinged cup holder 48 is illustrated in FIG. 10.
The cup holder 48 can be attached to one of the transverse support
member 30, 32, wherein the cup holder 48 pivots about a hinge 50.
The hinge 50 allows the cup holder 48 to remain in the proper
position as the member 30, 32 to which it is attached is
pivoted.
[0107] FIG. 11 is an alternate embodiment of the system 10 for
retrofit or factory installed applications. This system includes a
mouse pad armrest area. 18. A vertical adjustment 62 for the elbow
rest portion of the armrest 18 allows the user to raise and lower
the system 10. A second supporting surface 16 for supporting a
keyboard has a tiltable adjustment 65. Telescopic adjustment 66
allows the user to position the keyboard comfortably. An under seat
attachment method 70 for this particular model consisting of
semi-circle flap strapping looped over structural members and
secured by common means to an underside of the chair 11. If not
all, a number of the parts of this invention would be built for
universal application, allowing for left or right side of chair
attachment.
[0108] This invention's parts would be made of materials commonly
used for the above mentioned applications. Including but not
limited to various forms or metals, plastics, fiberglass, and
wood.
[0109] FIG. 12 shows an overheard view of a system 10 of the
present invention mounted to a chair 11. This system 10 includes
top support 74 including keyboard surface 76 and armrest 78. A
diagonal hinge 80 allows for a storage area beneath armrest 78.
[0110] FIG. 13 shows a top support 74 resting on a support frame
82, generally L-shaped. The heavier dotted line, outlines an open
recessed, channeled area 84. The supporting frame 82 slides in,
left and right, of the seated chair user, to align the keyboard as
desired. A friction fit U-shaped engaging bracket 86 holds the
hinged armrest top closed. This is shown in more detail in FIG. 14.
To remove the complete top support 74 from the support frame 82,
the user disengages the U-shaped bracket 86 by lifting the corner
of the top, opposite the hinged side, and then sliding the entire
top 74 all the way to the left.
[0111] Frame 82 includes end 88. End 88 fits within retainer 90
which is located on the underside of top support 74. The end 88 is
typically a four-sided structure. The end 88 slides out of the
4-sided retaining area 90 when the top support 74 is slid to the
left to remove top 74 completely from this support frame 82.
[0112] FIG. 15 shows an overhead view of a top surface 74. The top
surface 74 includes a recessed beverage holder 94. An outline of a
keyboard is denoted by dashed line 96. A recessed storage area 98
is located below beneath surface 76. Likewise, a recessed computer
mouse or other storage area 100 is on the upper hinged armrest 78.
A mouse pad 102 is designated by dotted lines. The top surface 74
also includes adjustable outside corner stops 104 to hold a
standard keyboard.
[0113] Referring to FIG. 16, the armrest surface 78 is shown hinged
open. An adjustable slide stop 105 is provided to secure a laptop
computer 96 or other device. The laptop 96 is shown in dotted
lines. The underside 106 of the hinged armrest 78 is visible when
the armrest 78 is open. A storage area 108 is located beneath the
armrest 78.
[0114] FIG. 17 shows frame 82 as part of a chair mounting system
110. The mounting system 110 includes telescope member 112 on which
top support 74 rests. The telescope member 112 allows in and out
movement of the top support 74 so the user can allows the chair
system user to adjust the top support 74 closer or farther away
from his/her body. The mounting system 110 further includes a
receiver 113 through which the telescoping member 112 is received
and attached. The receiver 113 includes a hinge 114. This hinge 114
allows the top support 74 to be pivoted upwardly and clockwise
(designated by 116) about the hinge 114 so the user may enter and
exit the chair.
[0115] The receiver 113 is fit within an outer receiving member 118
for vertical (up and down) telescopic movement. A spring stop knob
120 or other similar means maintains the receiver 113 at the proper
chosen level. Once again, there are many options to accomplish the
up and down movement. (spring assisted, pneumatic leveling.
etc.).
[0116] The mounting system 110 includes a first bracket or plate
122 for mounting to a chair with bolts, rivets, screws, epoxy,
welding or the like. The first bracket 122 includes a receiver
channel 124 a bracket portion 125 of the receiver member 113. The
receiver 113 is attached to the channel 124 using conventional
attachment means. In the embodiment illustrated, six or so short,
heavy self tapping screws 126 are provide to attach the first
bracket 122 to a chair. Four or more machine bolts 128 are slid up
through bracket 122 through springs 130 to threaded nuts 132.
[0117] Now referring to FIG. 18, an alternative method for
attaching a keyboard or the like, via a hinged channel 134. A
mating channel member 136 is adhesively attached to the underside
of the keyboard and slid or snapped into place.
[0118] U-shaped bracket 138 is attached top the underside of the
top support 74, and mates with telescopic support frame member
112.
[0119] The above stated mounting bracket system 110 accomplishes
two important mounting issues. First, the through bolted adjustable
bracket allows the system to be mounted to varied styles of seat
designs. Typically, task style chair seats curve up on the sides to
form a dished surface. The travel between bracket 122 and receiver
113 (90 degree angle bracket) allows the frame 82 to be mounted
under a chair seat, whether it be flat or curved upwards and at any
degree. Secondly, the spring-loaded bolts absorb, to a certain
extent most accidental downward or upward undo pressure applied to
the cantilevered top.
[0120] Now referring to FIG. 19, a cup holder 140 is illustrated.
The cup holder 140 includes a spring stop mechanism 142 for
attachment to the frame 82. The cup holder further includes an over
the top, snap on bracket 144, which attaches to the frame 82. When
the frame 82 is tilted as per arrow 146, the beverage remains in
upright position. This is accomplished by a pivotal bracket
connection. The cup holder 140 also includes a bump into notch
system 150 to hold the bracket 144 from sliding from side to side.
The bumps 152 are illustrated best in FIG. 19a.
[0121] FIG. 20 is an illustration of the top support 74 removed
from the chair. This figure represents a different use position for
the system 10 which allows the user to utilize the top support 74
in a location other than the chair. Here, the telescopic member 112
is removed completely from the receiving member 113. The L-shaped
frame 82 is then flipped over 180 degrees and inserted into a tight
friction fit area. The hinged armrest 78 is then closed so as to
engage bracket 138, which is also a friction fit bracket. A slip-on
foam pad 156 may be provided to rest on the user's lap when using
the system 10 after it has been removed from the chair. (See also
FIG. 21). The top support 74 may include recesses areas 158 on an
underside for a resting support surface on the user's knees.
[0122] FIG. 21 shows an over head view of the system 10 in use,
resting on a user's lap after its been removed from the chair.
[0123] FIG. 22 shows a top support 74. In this embodiment, the
mounting system 110 has a shortened horizontal support frame 162.
Here, the frame 82 remains attached to the chair when the top
support 74 is removed from the chair. This shorter frame 162 allows
for easier access and exiting from the chair seat. Further to this
embodiment, the mounting system 110 includes a receiver 164 for
receiving a telescopic member 166 located on the mounting system
110 for fixing the overall system 10 to a chair. A slide stop
mechanism 169 guards against misaligning the top support 72 with
the mounting system 110. This embodiment also includes a shorter
thigh rest bar. In operation, this version slides in and out along
the receiving member 164. This also can serve as a carrying handle
when in the second use position.
[0124] The embodiment of FIG. 23 is similar to that of FIG. 22.
However, this embodiment includes a pivoting support frame member
172 which pivots and slides to become a thigh rest. Another version
has a mirrored image structural support piece to match and nest
with support frame and fold open (butterfly) to become a thigh
rest. Another version has the complete frame piece (L-shape) being
one and sliding in and out.
[0125] FIG. 24 illustrates a top surface 74 having a built-in flip
up monitor screen 178 for computer or DVD use. The advantage to
having a smaller screen offset and to the side of the keyboard is
that its presence is unobtrusive.
[0126] FIG. 25 illustrates yet another embodiment of the present
invention. This embodiment includes a hinge 180 between a first
surface 76 and an armrest 78. The hinge 180 can be locked for lap
use. This embodiment includes raised curb/stops 186 to hold a
keyboard in place. Also, the bumpers may include spring-loaded
squeeze members on one or both sides 181. This function can also be
accomplished by other commonly known means such as stop knobs or
other etc. The armrest 78 includes a mouse holder 188, a beverage
holder 190, and a plurality of pen, pencil (electronic) or other
storage receptacles 192. The first surface 76 includes a shallow
storage area 194. A stabilizer 196 may pivot outwardly from the
armrest 78 for resting upon the users thigh for lap use.
[0127] The embodiment of FIG. 26 is similar to the embodiment of
FIG. 25. Here, the first surface 76 includes a graduated curb stop
198 to accommodate various sized devices on which to rest or
against which to abut. The armrest 78 includes a curved cut out top
200 to expose a beverage holder 202 below. The armrest 78 further
includes a hinged mouse pad storage area 204.
[0128] FIG. 27 is an illustration of a mounting system 110 for the
system. The mounting system 110 has clamping locations in at least
two points to squeeze a chair seat 210 for attaching the mounting
system 110 to the chair 11. The squeezing application would be
achieved by commonly known means including, but not limited to,
clamps, wing nut and bolts, or caulk gun type mechanism, etc.
[0129] The mounting system 110 includes an upper bracket 207 having
a first stabilizing flange 212 which rests on the upper seat
portion of the chair 11. A second stabilizing flange 214 extends
downwardly from the first flange 212 to form an L-shape. The second
flange 214 is located along an edge of the chair 210. A separate
lower bracket 216 is fixed to the bottom of the chair 217. The
lower bracket 216 include an upwardly extending flange 218 which is
joined to the second stabilizing flange to connect the upper
bracket 207 to the lower bracket 216. The upper and lower brackets
may be attached using any fastening option, nut and bolt or the
like and would in at least two locations, attaching L-shaped top
seat bracket to the L-shaped under bracket. A plurality of vertical
support frame members 220 extend upwardly for added stability.
[0130] FIG. 28 illustrates yet another embodiment of the present
invention. This embodiment includes a top support 74 including a
first longitudinal surface 76 adapted for extending along the front
of a chair. An armrest 78 extends along one side of the chair 11 to
form a generally L-shaped structure in use. Arrows indicate the
movement of the top support 74.
[0131] FIGS. 29-30 illustrate movement of the first surface 76. The
first surface 76 pivots and slides for chair seat entering and
exiting. The first surface 76 pivots about a pivot point 238 until
it is substantially in line with (parallel) and above the armrest
78. A pin 239 joins the first surface 76 with the armrest 88 and
traverses within a guide 242 for alignment. The first surface 76
can be traversed toward the rear of the chair 11 substantially over
the armrest 78. In other words, the first surface 76 pivots away
from the user, and then or simultaneously slides back toward the
rear of the chair occupant to overlay in substantially vertical
alignment with at least a portion of the mouse pad/armrest area 78.
This embodiment can be attached to a chair or a desk using any
conventional means for attachment, including but not limited to a
retractable arm, a type of which is commonly provided with
permanently mounted under-desk keyboard supports.
[0132] Similar to other embodiments, this system includes a mouse
pad area. 240, and any number of cup holders, storage recesses, pen
holders, etc. Accordingly, the first surface 76 and the armrest 78
include hinges for lifting upper members under which the storage
recess etc. may be located. This embodiment may be equipped to
portably mount to the underside of a traditional desk, similar to a
conventional pull-out keyboard drawer or retractable arm
mount-style. The first surface 76 could include features not found
on a typical under-mount style keyboard tray. In essence, this
embodiment is comprised of one single support surface which can
transition portably between a desk mounted use position to a
convenient and comfortable lap use.
[0133] FIGS. 31 and 32 illustrate how the system 10 first surface
76 may pivot and overlay the armrest 78. The top support 74
includes a tracking (guide) member 242, such as a channel, slot, or
track. The tracking member 242 is mounted along an inside edge of
the armrest 78. The tracking member 242 may be a channel wherein a
downwardly extending pin 244 mounted to the underside of the first
surface 76 may traverse within the channel 242. The pin 244 may
also travel with a guide or slot 245 located within the first
surface 76 for left to right and/or north to south movement as an
alignment means. Accordingly, the guide 245 may be L-shaped as
illustrated in FIG. 32.
[0134] The first surface 76 of this embodiment and the embodiments
that follow is joined to the second surface at least by pin 244
offset on a separate substantially horizontal plane than the second
surface 78, preferably on a higher plane. This method allows the
first surface 76 to slide and overlap the second surface 78; i.e.
pivot or rotate along a horizontal plane, preferably the horizontal
plane on which the first surface 76 is positioned. The sliding and
overlapping application requires no significant fastening demands
as these components merely rest upon the system's top support
74.
[0135] FIGS. 33 and 34 show the top support 74 removed from the
chair or desk mounted framework in its portable or lap rest use
position. FIG. 33 shows the mouse pad 250 and armrest 78 rotated
approximately 90 degrees on the pivot 238, revealing an auxiliary
area of mouse pad 250 where as the right side of the armrest 78
(when chair mounted) rotates to become a thigh rest for lap use.
FIG. 34 shows the combination mouse pad and thigh rest tracking
north and south to adjust location in reference to the keyboard
support surface to best suit the user.
[0136] The embodiment of FIGS. 35-36 is similar to the embodiments
of FIGS. 31-34. The most significant variation is that this
embodiment has the first surface 76 and the mouse pad surface 250
as one on the same horizontal plane and traveling together. The
advantage of having the first surface 76 as one is that when the
first surface 76 is tracked to the side of the chair 11 and is
overlaying the armrest 78, the mouse and mouse pad 250 are still
accessible.
[0137] In FIG. 36 the system 10 first surface 76 is adjusted east
and west or left and right of the seated chair user. This is
accomplished as first surface 76 includes an L-shaped slot/channel
245, which acts as a further alignment means. Armrest 78 includes
slot/channel 242 transverse to slot 245. Pin 244 is snug fir within
the guides 245, 242 for reliable traversing through same. This
allows for east to west (or right to left) movement along a
substantially horizontal plane within or along guide 245 and north
to south (or in and out) movement along a substantially horizontal
plane within or along guide 242.
[0138] FIG. 37 illustrates a variation of a telescopic member as
previously described. A portion of the armrest 78a remains
permanently attached to a chair mounted support framework 110.
Another portion of the armrest 78b is removable from the framework
110 along with the first surface 76, and abuts the fixed portion of
the armrest 78a when the attached to the framework 110. Arrow 274
shows slideable north and south adjustment along a substantially
horizontal plane in relationship to a seated chair user. Arrow 276
shows the slideable travel for pin 244 in track/slot 245. Member
282 is permanently attached to the support framework 110. Member
282 generally includes a flange 282a extending horizontally outward
relative to a seated user and a smaller flange 282b extending in an
opposite direction, horizontally inward relative to a seated user.
Member 282 is adapted to friction fit within guide or channel 283
located on the underside of armrest 78b. Accordingly, guide 283
includes a larger lip 283a for engaging larger flange 282a, and
smaller lip 283b for engaging smaller flange 283b. By lifting top
support 74 as arrow 286 and sliding slightly, the top support 74 is
detached from chair mounted framework 110 and is ready for portable
use.
[0139] Referring to FIGS. 38-45, the embodiment as previously
described further includes additional pin 330 that traverses
through curvilinear guide 332 providing still further alignment
means. This contact point enhances the strength of the cantilevered
keyboard first surface 76 and provides an additional pivot point.
The curvilinear shape of guide 332 also allows the top surface 74
to traverse in a north to south (in and out) component along a
transverse substantially linear portion of the guide 332 and/or in
a motion that has both north to south (towards and away relative to
a seated user) and east to west (left to right relative to a seated
user) components as pin 330 traverses along an arcuate portion of
guide 332.
[0140] FIG. 39 shows the first surface 76 rotated away from the
user. This is accomplished by the top pivoting on pin 244, and pin
330 traveling inside or along edge of guide 332.
[0141] FIG. 40 shows the pivot pin 244 traveling in track 242 (as
previously submitted) to further adjust keyboard support overlaying
mechanism. This motion may be carried out simultaneously, as first
surface 76 is pivoted outwardly.
[0142] This motion reveals the cantilever support pin 330 tracking
location. This area of invention aids secondary support. Pin 330
disengages as the first surface moves to overlay the armrest 78.
Tracking may also run along the outside edge of the underlying
support structure, as well as a number of other commonly known
methods of accomplishing this needed structural element.
[0143] Note the rotation of the two adjoining support surfaces to
ready the top support 74 for its lap use position. Pin 244 now
travels along guides 242 and 245, and Pin 330 now travel along
guide 332, as can be clearly seen in FIGS. 39 and 43. The
combination of the multiple movements in two tracking locations
allows for numerous adjustments in a plurality of directions. The
pin 244, 330 may be spring loaded to absorb downward pressure
applied to cantilevered top.
[0144] Specifically referring to FIG. 41, the top surface 74 is
shown "nested" with the first surface 74 in substantial parallel
and vertical alignment with the armrest 74b. This position is also
used for transport and/or storage of the top support 74 when the
top support 74 is removed from the chair.
[0145] FIG. 45 shows the system in lap use.
[0146] FIG. 46 shows the a chair 11 with the frame 110 and fixed
armrest 78a with the top support 74 removed.
[0147] FIGS. 47 and 48 illustrate a variation of the previous
embodiment. Here. the alignment means allows the chair mounted top
support 74 to traverse farther south or inwardly relative to the
user. This additional movement would allow a chair 11 with a
mounted top support 74 to fit under a desk without the top support
74 acting as an impediment. Referring to FIG. 48, this embodiment
includes a secondary tracking system 350. This secondary tracking
system 350 uses a mechanism similar to a drawer slide tracking
mechanism. This secondary tracking system 350 includes a third
tracking member which allows further telescopic movement to move
the top support 74 farther away from the desk. Further, the
secondary tracking system may include drawer slides employing the
third tracking member, guides, and rollers that guide and support
the top support 74 permitting easy operation.
