Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to a UPS uninterruptible power
supply mobile computer table structure wherein an
ascending/descending device having a transmission motor is utilized
to cooperatively work with an IC control panel equipped with a set
of ascending and descending buttons; whereby, the ascending or
descending button is simply pressed to actuate an operational tube
of the ascending/descending device spinning lineally upwards or
downwards along a threaded shaft to adjust the position of an inner
tube so as to precisely locate a table panel and a monitor at
desired positions thereby, providing more convenient and ergonomic
design thereby.
[0002] Conventional UPS uninterruptible power supply portable
computer table is characterized by the use of pneumatic cylinders
or elastic cords to control the ascending and descending movement
of a monitor and a table panel thereby. In application, pressing
force is exerted onto the table panel so as to lower downwards an
inner tube. In case of an excessive force applied thereto, the
inner tube will descend too fast and fail to locate the table panel
and the monitor precisely at desired positions. Thus, the computer
table must be readjusted to reach the demanded position, which is
quite inconvenient in both application and adjustment.
SUMMARY OF THE PRESENT INVENTION
[0003] It is, therefore, the primary purpose of the present
invention to provide a UPS uninterruptible power supply mobile
computer table structure wherein a transmission motor of an
ascending/descending device is utilized to cooperatively work with
an IC control panel equipped with a set of ascending and descending
buttons; whereby, the ascending or descending button is simply
pressed to actuate an operational tube spinning lineally upwards or
downwards along a threaded shaft to adjust the position of an inner
tube and locate a base panel and a monitor at desired positions
thereby, permitting accurate adjustment of the computer table
without the repeated operation of the pneumatic cylinders or
elastic cords of the conventional portable computer table to
provide more a convenient and ergonomic design in application and
adjustment thereby.
[0004] It is, therefore, the second purpose of the present
invention to provide a UPS uninterruptible power supply mobile
computer table structure wherein the ascending/descending device is
accommodated into an outer tube with an inner tube joined therein
and, via rectangular passageways preset at a platform of the
ascending/descending device and a base panel, the inner and outer
tubes are reciprocally communicated so that wires respectively
linked to the transmission motor, the IC control panel, the monitor
and storage battery can be guided there-through and concealed at
the inner and outer tubes therein, permitting free movement of the
computer table without being interfered by the wires thereof as
well as allowing a clean and neat appearance thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0019] Please refer to FIG. 1 showing an assembled perspective view
of the present invention. The present invention relates to a UPS
uninterruptible power supply mobile computer working table
structure, comprising a mobile computer table 10 composed of an
outer tube 11 and an inner tube 12 pivotally mounted to the
interior of the outer tube 11 wherein both outer and inner tubes
11, 12 are identically shaped into an oval and hollow tubular
configuration, and a set of conjoining edges 111 are disposed
extending vertically at both lateral sides of the outer tube 11 to
match to conjoining grooves 121 defining both lateral sides of the
inner tube 12 thereon. Support feet 14 with casters 13 attached
thereto are provided symmetrically extending at the lower section
of the conjoining edges 111 of the outer tube 11 thereon, and a
table panel 15 is fixed at the upper section of the inner tube 12
thereon. The bottom side of the table panel 15 can have a drawer
chamber 151 (or without the drawer chamber 151 as shown in FIG. 8)
attached thereto, and beneath the drawer chamber 151 is set a
pullout panel 152 for the location of a keyboard 153 thereon. An
extension rack 16 equipped with an angle-adjustable seat 161 as
shown in FIG. 2 is provided protruding at the top edge of the inner
tube 12 for the mounting of a monitor 162 thereto. The monitor 162
cooperatively works with a UPS uninterruptible power supply system
so as to function normally for wireless receiving/inquiring
information (e.g. case histories). The table panel 15 has an
ascending button 154, a descending button 155, and a power supply
signal light 156 disposed at one side thereon that are conductively
linked to an IC control panel 157 to control the operation of an
ascending/descending device 20 as shown in FIG. 3 thereby. The
ascending/descending device 20 is made up of a U-shaped support
frame 21 mounted to the internal bottom end of the outer tube 11
and synchronically locked to the support feet 14 for location
thereby. A platform 211 similarly shaped like the outer tube 11 is
attached to the topside of the support frame 21 wherein an L-shaped
support plate 212 and a U-shaped retaining plate 213 are
respectively situated at both sides of the platform 211 thereon,
and a transmission motor 22 is mounted to the support plate 212 at
one side thereof. The other side of the transmission motor 22 is
fixed to an outer cover 23 made up of a pair of opposite housings
231 that are correspondingly engaged with each other as shown in
FIG. 4, permitting a spiral-threaded rod 221 of the transmission
motor 22 to extend precisely through one housing 231 and
accommodate at the interior of the outer cover 23 therein. The
housings 231 are respectively equipped with a fixing plate 232
extending at the bottom edges thereon to clamp the U-shaped
retaining plate 213 there-between and securely locked thereto. Both
housings 231 have a restricting cavity 233 disposed at one internal
corresponding side thereon respectively, and a threaded shaft 24
equipped with a bearing 241 and a driven gear 242 is mounted into
the restricting cavities 233 for location thereby. The driven gear
242 thereof has helical teeth defining the circumferential surface
thereon to precisely mesh with the spiral-shaped rod 221 thereby,
and the two restricting cavities 233 have a through hole 234 formed
at the top surface thereon for the threaded shaft 24 to extend
there-through and protrude outside the outer cover 23 thereby. An
operational tube 25 with a screw-threaded hole 251 defining the
bottom end thereon is provided to screw-join to the threaded shaft
24 thereby wherein the inner diameter of the operational tube 25 is
larger than the threaded shaft 24 and the top of the threaded shaft
24 has a stop side 243 larger than the screw-threaded hole 251
thereof. A sleeve cylinder 26 is positioned to abut against the
topside of the outer cover 23 so as to sheath and hide the
operational tube 25 in the interior thereof. A sealing cap 262
defined by a pivoting hole 261 thereon is attached to the top edge
of the sleeve cylinder 26 for the extension of the operational tube
25 there-through. The operational tube 25 also includes a set of
assembling holes 252 symmetrically drilled at the opposite side of
the upper end thereon. And a base panel 27 with a pivoting tube 271
protruding thereon is securely locked to the bottom edge of the
inner tube 12 thereof. The pivoting tube 271 has a set of assembled
holes 272 symmetrically cut at both opposite sides thereon to match
and secure to the assembling holes 252 thereby when the operational
tube 25 is guided to extend through the pivoting tube 271 thereof.
In addition, one side of the platform 211 and the center of the
base panel 27 are respectively defined by a rectangular passageway
2111, 273 thereon (referring to FIG. 3) so as to communicate the
outer tube 11 and the inner tube 12 with each other thereby. Thus,
wires A respectively linked to the transmission motor 22, the IC
control panel 157, the monitor 162, and storage battery 30 can be
guided to extend through the rectangular passageways 2111, 273 and
conceal inside the inner and outer tubes 11, 12 thereby.
[0020] To adjust the position of the table panel 15 and the monitor
162 in height (referring to FIGS. 5, 6), the transmission motor 22
of the ascending/descending device 20 is utilized to cooperatively
work with the IC control panel 157 equipped with the ascending
button 154 and the descending button 155 thereof. In operation, the
ascending button 154 (or the descending button 155) is pressed
downwards, and the spiral-shaped rod 221 of the transmission motor
22 is then conducted to rotate counterclockwise (or clockwise) and
synchronically actuate the driven gear 242 and the threaded shaft
24 to spin oppositely in clockwise (or counterclockwise) movement
accordingly. Meanwhile, the top edge of the operational tube 25 is
securely locked to the pivoting tube 271 of the base panel 27,
permitting the screw-threaded hole 251 actuated by the clockwise
(or counterclockwise) rotation of the threaded shaft 24 to screw
upwards and ascend (or screw downwards and descend) in a lineal
movement therewith. Thus, the base panel 27, the inner tube 12, the
table panel 15 and the monitor 162 are synchronically actuated
therewith to lift upwards (or lower downwards) along the outer tube
11 (as shown in FIG. 7) till reaching a desired position. Then,
when the ascending button 154 (or the descending button 155) is
stopped from the pressing operation, the transmission motor 22, the
threaded shaft 24, and the inner tube 12 will immediately cease the
movement so that the monitor 162 and the table panel 15 can be
precisely controlled to locate at an adjusted position with an
accuracy, omitting the repeated operation of the pneumatic cylinder
or elastic cords shown in the conventional portable computer
tables. Therefore, the mobile computer table 10 of the present
invention offers a more convenient and ergonomic design in
application and adjustment thereof.
[0021] Furthermore, when the operational tube 25 keeps screwing
upwards to reach the top edge of the threaded shaft 24, the
operational tube 25 will be hindered by the stop side 243, and the
threaded shaft 24 with the transmission motor 22 will be ceased
from operation so as to protect the transmission motor 22 avoiding
idle spinning thereby. Besides, the operational tube 25 can be
prevented from climbing upwards continuously so as to avoid the
risk of detaching from the threaded shaft 24 thereof. Otherwise,
when the operational tube 25 is screwed to descend downwards till
reaching the top surface of the restricting cavities 233 and
stopped thereby, the threaded shaft 24 and the transmission motor
22 will immediately cease the operation thereof. Therefore, the
operational tube 25 and the inner tube 12 are restricted to ascend
or descend between a topmost point and a bottommost point and
automatically positioned there-between, achieving the best
application state of the present invention.
[0022] Please refer to FIG. 9. The conjoining edges 111 and the
conjoining grooves 121 thereof can be disposed at the
circumferential surface of both lateral sides or four sides (as
shown in FIG. 14) of the outer and inner tubes 11, 12 thereon
wherein the conjoining grooves 121 thereof can be molded into a
dove-tailed groove configuration respectively, and a guide sliding
unit 40 is mounted into each conjoining groove 121 thereof. The
guide sliding unit 40 (as shown in FIGS. 10, 11) is made up of a
fixed element 41, an actuating element 42, and a linking element 43
equipped with a plurality of rolling balls 431 arranged at both
lateral sides thereon. The fixed element 41 and the actuating
element 42 are formed into U-shaped plates that are correspondingly
joined to each other and respectively riveted to the upper section
of the conjoining edge 111 of the outer tube 11 and the preset
position of the conjoining groove 121 of the inner tube 12 for
secure attachment thereto as shown in FIG. 12. The linking element
43 is situated to sandwich between the fixed element 41 and the
actuating element 42 thereof, permitting the rolling balls 431
attached at both lateral sides of the linking element 43 to
precisely contact and abut against both lateral sidewalls of the
fixed element 41 and the actuating element 42 with a lubricating
effect formed thereby. A positioning stop portion 421 is bent to
extend horizontally at the top edge of the actuating element 42 so
as to contact evenly with the topside of the fixed element 41
thereby.
[0023] When the ascending/descending device 20 is started to adjust
the height of the inner tube 12 as shown in FIG. 13, the actuating
element 42 of the guide sliding unit 40 will be synchronically
moved therewith. Meanwhile, the conjoining edges 111 and the
conjoining grooves 121 of the outer and inner tubes 11, 12 thereof
can offer a positioning effect to restrict the fixed element 41 and
the actuating element 42 of the guide sliding unit 40 thereby,
permitting the actuating element 42 moved by the inner tube 12
thereof to simply climb upwards along the fixed element 41 and the
rolling balls 431 of the linking element 43 thereof to achieve the
guiding and sliding effect thereby. Therefore, the inner tube 12 is
accurately limited by the guide sliding unit 40 to ascend or
descend in a stable and smooth manner, efficiently preventing the
vibration of the monitor 162 and the table panel 15 in the
adjusting operation to achieve the best state of application
thereby.
