Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a lifted type computer desk
set and particularly to computer desk set in which a movable desk
board can be lifted relative to a main desk board to reveal the
keyboard for operation a computer or move backward to form a flat
desk top.
[0003] 2. Description of Related Art
[0004] It is known that the computer has been popular over the
ordinary families in addition to being an indispensable tool in all
businesses in this information era. Due to various computerized
equipment being available, the study room or the bedroom in a house
are too limited to place the computer and related peripheries.
Thus, it is a core problem to settle the computer and the related
peripheries such that it is required to consider if the input
device such as the keyboard or the mouse can be operated and if the
space is available for reading and writing. Accordingly, the
so-called computer desk set has been developed and made for the
need.
[0005] The conventional computer desk set losses the function of a
desk because of CRT display occupying most space of the desktop so
that the manufacture has developed an under-desk type design of the
computer desk set to keep the desktop flat and to avoid the harm of
radiation at the same time. However, the under-desk type computer
desk set has deficiencies in that the data material has to be
passed over the display and leave it at a far front side or a
lateral side between the user and the display. It results in the
tired eyes of the user and fatigues and harms of the shoulder, the
neck, the waist and the vertebrate after a long period of
using.
[0006] Currently, there is a trend that the liquid crystal display
is becoming the main stream of computer display. Hence, the
under-desk type computer desk set has been incompatible with the
needs. Usually, the small sized liquid crystal display is placed on
the desktop next to a desk edge opposite to the user or clamped to
the desk edge. While in use, the total distance between the user
and the display is the depth of the desk and the pulled out portion
of the keyboard rack such that the user is obliged to lean forward
in order to see the typed data shown on the display. In this way,
it is very easy to cause the over used eyes and the muscle fatigue
resulting from incorrect posture.
SUMMARY OF THE INVENTION
[0007] The crux of the present invention is to provide a lifted
type computer desk set, which includes a desk body and a movable
desk board. The desk body has a main desk board at the top thereof,
a recess opening at the front side thereof and a keyboard rack at
the lower side thereof and is supported with a leg device. The
movable desk board has the size and the shape thereof corresponding
to the recess opening and is pivotally connected to one or two
lateral edges of the recess opening with a pivot part. A keyboard
on the keyboard rack can be revealed while the movable desk board
is lifted such that a sight distance to the display can be
shortened.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0017] Referring to FIG. 1, a computer desk set with a movable desk
board according to the present invention is basically comprised of
a desk body 1, a movable desk board 2 and at least a pivot part
3.
[0018] Wherein, the desk body 1 at the top thereof is a main desk
board 11 and the main desk board 11 at the front side thereof has a
recess opening 111 for receiving the movable desk board 2. A
keyboard rack 12 is fixedly disposed under the recess opening 111
for placing a keyboard A. The main desk board 11 at two opposite
lower lateral sides thereof connects with a conventional leg part
13 for supporting the main desk board 11 so as to form the desk
body 1. The leg part 13 as shown in FIG. 1 is provided with four
leg posts 131 but it is noted that the leg part 13 provided with
the leg posts 111 is an example only and any other leg part 13
possible to support the main desk board 11 or a support structure
used for the partition screen in OA office furniture can be
adopted.
[0019] The movable desk board 2 has a size with the shape thereof
corresponding to the recess opening 111 so as to be inserted into
the recess opening 111 and the movable desk board 2 is pivotally
connected to one or two lateral edges of the recess opening 111
with the pivot part 3 respectively such that the movable desk board
2 can be lifted up or pressed down rotationally relative to the
main desk board. Besides, in order to be flash with the main desk
board 1 during closing the recess opening 111, the movable board 2
at the rear side thereof has an oblique board edge 21 to intersect
with an oblique recess edge 112 at the rear side of the recess
opening 111.
[0020] The pivot part 3 is composed of a pivot seat 31 and a
bearing seat 32. The pivot seat 31 has a pivot post 311 to be
inserted into a corresponding bearing hole 321 at the bearing seat
32 such that the pivot seat 31 can rotate with respect to the
bearing seat 32. As soon as the pivot seat 31 and the bearing seat
32 are fixedly attached to the lateral sides of the movable board 2
in a way of corresponding to each other, the movable board 2 can
perform the function of being lifted up or pressed down.
Alternatively, the pivot part 3 can be the rotational shaft with a
function of positioning stagnation, which is utilized in a notebook
computer, so that it is possible for the movable board 2 to
stagnate at a certain position as desire during the process of
being lifted up or pressed down.
[0021] Referring to FIGS. 2A and 2B, a liquid crystal display B is
placed at the rear side of the main desk board 11 and the movable
desk board 2 can be lifted to reveal the keyboard rack 12 under the
front side of the main desk board 11 before the computer being
started such that the user can operate the keyboard A directly
without pulling out the keyboard rack 12. Because the keyboard A is
flush with or disposed deeper inside than the front side of the
main desk board 11 and occupies little space, the sight distance
can be reduced during the computer desk set of the present
invention is used so that harms such as over used eyes and fatigued
muscle can be diminished effectively.
[0022] In order to promote the work efficiency and to utilize the
limited space effectively, as shown in FIGS. 3 and 4, the movable
desk board 2 at the rear side thereof is possible to be mounted
with a reading shelf 4 for holding books or documents different in
size and thickness so as to facilitate reading or data recording or
typing. The reading shelf 4 provides two guide rods mounted to the
rear side of the movable desk board 2 in parallel with a gap formed
between the movable desk board 2 and each guide rod 41 and an L
shaped support frame 42 for placing books or documents with the
horizontal plate portion of the support frame 42 having two
eccentric holes 421 passed through by the two guide rods 41 such
that the support frame 42 can be moved longitudinally along the
guide rods 41. Referring to FIG. 4, the eccentric holes 421 are
perpendicular to the guide rods 41 during the support frame 42
tilts backward so that the support frame 42 can be slid adjustably.
When the books and the documents are placed on the support frame
42, the support frame 42 becomes horizontal due to the moment of
the books and the documents such that the eccentric holes 421
become oblique to jam the guide rods 41 and prevent the support
frame 42 from sliding downward. Besides, a spring plate 422 can be
added at the back of the upright plate portion of the support plate
42 to keep the support plate 42 in a state of jamming.
[0023] Further, the two guide rods 41 at the upper parts thereof
have a press piece 43 respectively and the press piece 43 is a
stick 431 at both ends thereof extending an arm end 432
respectively. Each of the arm ends 432 at the free end thereof has
a catch part 433 and it can be seen in FIG. 4 that the catch part
433 is a sharp cone shape. But, it is noted that the catch part 433
can be another shape such as a ball, a hand palm or a foot palm
except the sharp cone to enhance the pleasure of reading. The stick
431 at the intersection of the corresponding guide rod 41 extends a
guide part 434 such as a projection or a recess to catch the guide
rod 41 so as to be adjusted longitudinally for complying with the
size of the book or the document. When the stick 431 moves to
clamped article, the stick 431 turns downward to allow the catch
part 433 pressing the books or the documents firmly.
[0024] Referring to FIG. 5, it can be seen that a liquid crystal
display is mounted to the rear side of the movable desk board and,
in this way, the work efficiency can be promoted and the space can
be utilized effectively.
[0025] Referring to FIGS. 6 and 7, the movable desk board 2 and the
main desk board 11 are turned by way of the pivot part 3 and a stop
part 5 is disposed at a lateral edge of the recess opening 111. The
stop part 5 at an elongated groove 51 thereof is passed through
with a conventional fastener such as a screw such that the stop
part 5 can be attached to the bottom side of the main desk board
11. The user can adjust the stop part 5 forward or backward to
change the position of a lateral extending stop tongue 52 at an end
thereof such that the movable desk board 2 can be retained with the
stop tongue 52 due to a shear force and the elevation angle of
movable desk board 2 can be changed intentionally to a proper
location. Hence, the user can adjust the reading shelf 4 to a
proper angular position by way of the preceding adjustment to
acquire the most comfortable environment for operating the
computer, reading and writing.
[0026] It is appreciated that a lifted type computer desk set
according to the present invention has the advantages listed
hereinafter:
[0027] (1) The computer desk set of the present invention can be
formed as an ordinary desk in addition to being possible for
operating the computer. Further, the movable desk board can be
pivotally lifted as a reading shelf for holding books or documents
different in size and thickness and being available for reading
books or printing data.
[0028] (2) The computer desk set makes the display, books,
documents, the keyboard and the user being lined up without
deviation so that the user can feel the comfort resulting from the
human engineering.
[0029] (3) Owing to the keyboard rack being unnecessary to be
pulled out before the keyboard being operated, the sight distance
between the keyboard and the display can be shortened to decrease
the harm resulting from the over used eyes and muscle fatigue. In
addition, the computer desk set of the present invention offers a
sound work environment in accordance with the requirement of the
human engineering and a well arrangement of limited space.
[0030] While the invention has been described with reference to the
a preferred embodiment thereof, it is to be understood that
modifications or variations may be easily made without departing
from the spirit of this invention, which is defined by the appended
claims.
