BACKGROUND OF THE INVENTION
Field of the Invention
[0001] The present invention relates to adjustable tables, and more
particularly, to an adjustable table provided with adjustable
inclined angle and table height.
Description of the Related Art
[0002] Tables and chairs are commonly applied by people for various
purposes. For example, a table and at least a chair are usually
required for facilitating demands of dining, document processing,
or office operation. In addition, the time of people applying
tables and chairs is relatively long nowadays. In case the height
of the table and the chair mismatches the body shape of the user,
the user might feel body pain or limbs ache after using the table
and chair for a long period. Therefore, sizes of the table and
chair are in direct relation to the body shape of the user.
[0003] However, most of the tables presently available are provided
with a fixed side, so that the size is not able to be adjusted
based on different users demand, failing to meet the ergonomics.
Also, regarding to a recently provided adjustable table in the
market, one of the inclined angle and the table height is able to
be adjusted; however, such adjustable tables are only able to
partially resolve the issue for the user, with other disadvantages
and inconveniences remaining to be improved.
[0004] Therefore, a table provided with an adjustable inclined
angle and table height is needed for meeting the demand of users
with different body shapes.
SUMMARY OF THE INVENTION
[0005] For improving the issues above, an adjustable table provided
with adjustable inclined angle and table height is disclosed. With
a first support rack pivotally swaying against the foot, height of
the table board is adjustable; with a second support rack pivotally
swaying against the first support rack, the inclination of the
table board is adjustable. Therefore, both the height and the
inclination of the table are allowed to be adjusted, facilitating
the utility of the table.
[0006] For achieving the aforementioned objectives, an embodiment
of the present invention provides a table with adjustable height
and inclination, comprising:
[0007] a foot;
[0008] a first support rack clutchably and pivotally combined with
the foot;
[0009] a second support rack clutchably and pivotally combined with
the first support rack, the second support rack also fixed to a
table board;
[0010] a first positioning assembly disposed at a location of the
pivotal combination between the first support rack and the foot,
the first positioning assembly moving between a fastened status and
a loosened status to vary a status of a pivotal combination between
the first support rack and the foot so as to adjust and fix an
angle of the first support rack swaying against the foot; and
[0011] a second positioning assembly disposed at a location of the
pivotal combination between the first support rack and the second
support rack, the second positioning assembly moving between a
fastened status and a loosened status to vary a status of a pivotal
combination between the first support rack and the second support
rack so as to adjust and fix an angle of the second support rack
swaying against the first support rack.
[0012] With such configuration, user is able to adjust the table
inclination based on different user demands by swaying the second
support rack against the first support rack. Also, user is able to
sway the first support rack against the foot for adjusting the
table height against the ground. Therefore, utility of the table
provided by the present invention is enhanced.

placed on the ground. The foot 10 includes a left foot rack 11 and
a right foot rack 12, with a connection board 13 transversely
fastened between the left foot rack 11 and the right foot rack 12.
The left foot rack 11 and the right foot rack 12 are formed in an A
shape. The connection board 13 is able to be used for holding
objects.
[0025] The first support rack 20 has one side thereof pivotally
connected with the foot 10 and the other side thereof capable of
pivotally swaying for adjusting the distance between the first
support rack 20 and the ground. In an embodiment of the present
invention, the first support rack 20 includes a first moving arm
21, a first fixing arm 22, and a first linkage 23 disposed between
the first moving arm 21 and the first fixing arm 22. The first

are combined in axial alignment, wherein the inner tube 231 is
fastened to the left foot rack 11, and the outer tube 232 has one
end fixed to the first fixing arm 22 and the other end passing
through the first moving arm 21 and the right foot rack 12.
[0026] The second support rack 30 is fixed with a table board 40.
The second support rack 30 has one side thereof pivotally connected
with the first support rack 20 and the other side thereof
triggering the table board 40 to pivotally sway for adjusting the
inclination angle of the table board 40. Also, in an embodiment of
the present invention, the second support rack 30 includes a second
moving arm 31, a second fixing arm 32, and a second linkage 33
disposed between the second moving arm 31 and the second fixing arm
32. The table board 40 is fixed to the second fixing arm 32 and the
second moving arm 31. The second linkage 33 includes an inner tube
331 and an outer tube 332 that are combined in axial alignment,
wherein the inner tube 331 is fastened to the first fixing arm 22,
and the outer tube 332 has one end fixed to the second fixing arm
32 and the other end passing through the second moving arm 31 and
the first moving arm 21.
[0027] The first positioning assembly 50 is disposed at the
location of the pivotal combination between the first support rack
20 and the foot 10. The first positioning assembly 50 is allowed to
be loosened or tightened, so as to adjust an angle of the first
support rack 20 swaying against the foot 10. The first positioning
assembly 50 includes a handle 51 and a resilient member 52. In an
embodiment of the present invention, two resilient members 52 are
applied. The handle 51 passes through and is screwed to the right
foot rack 12 and the inner tube 231. The two resilient members 52
are mounted around two ends of the inner tube 231 and contact the
two ends of the outer tube 232, respectively. As shown by FIG. 6
and FIG. 7, when the first positioning assembly 50 is at a fastened
status, the handle 51 is rotated to be fastened, such that the
handle 51 pushes against the first support rack 20, and the first
support rack 20 presses the foot 10, while the resilient member 52
is pressed by the outer tube 232 at the location of the pivotal
combination between the first support rack 20 and the foot 10.
Therefore, the angle of the first support rack 20 swaying against
the foot 10 is fixed. When the first positioning assembly 50 is at
a loosened status, the handle 51 is rotated to be loosened, such
that the first support rack 20 laterally moves against the foot 10
due to the resilient force of the resilient member 52. Therefore,
the angle of the first support rack 20 swaying against the foot 10
is able to be adjusted.
[0028] In addition, the first positioning assembly 50 comprises a
first pillar 53 and a plurality of first grooves 54. The first
pillar 53 is disposed on the first support rack 20. The first
grooves 54 are disposed on the foot 10 in an equiangular
arrangement, such that the first support rack 20 and the foot 10
are allowed to be engaged. When the first positioning assembly 50
is at the loosened status, as shown by FIG. 7, the first support
rack 20 is allowed to sway to a targeted angle against the foot 10,
while the first pillar 53 is in alignment with one of the first
grooves 54. Subsequently, the handle 51 is rotated to be fastened
again, such that the first support rack 20 is pushed against the
foot 10. Therefore, the first pillar 53 is engaged in the first
groove 54 for adjusting and fixing the angle included by the first
support rack 20 and the foot 10, as shown by FIG. 6.
[0029] The second positioning assembly 60 is structurally similar
to the first positioning assembly 50. The second positioning
assembly 60 is disposed at the location of the pivotal combination
between the first support rack 20 and the second support rack 30.
The second positioning assembly 60 is allowed to be loosened or
tightened, so as to adjust the angle of the second support rack 30
swaying against the first rack 20. The second positioning assembly
60 comprises a handle 61 and a resilient member 62. In an
embodiment of the present invention, two resilient members 62 are
applied. The handle 61 passes through and is screwed to the first
fixing arm 22 and the second fixing arm 32. The two resilient
members 62 are mounted around two ends of the inner tube 331 and
contact the two ends of the outer tube 332, respectively. When the
second positioning assembly 60 is at a fastened status, the handle
61 is rotated to be fastened, such that the handle 61 pushes
against the second support rack 30, and the second support rack 30
presses the first support rack 20, while the resilient member 62 is
pressed by the outer tube 332 at the location of the pivotal
combination between the second support rack 30 and the first
support rack 20. Therefore, the angle of the second support rack 30
swaying against the first support rack 20 is fixed. When the second
positioning assembly 60 is at a loosened status, the handle 61 is
rotated to be loosened, such that the second support rack 30
laterally moves against the first support rack 20 due to the
resilient force of the resilient member 62. Therefore, the angle of
the second support rack 30 swaying against the first support rack
20 is able to be adjusted.
[0030] In addition, the second positioning assembly 60 comprises a
second pillar 63 and a plurality of second grooves 64. The second
pillar 63 is disposed on the second support rack 30. The second
grooves 64 are disposed on the first support rack 20 in an
equiangular arrangement, such that the second support rack 30 and
the first support rack 20 are allowed to be engaged. When the
second positioning assembly 60 is at the loosened status, the
second support rack 30 is allowed to sway to a targeted angle
against the first support rack 20, while the second pillar 63 is in
alignment with one of the second grooves 64. Subsequently, the
handle 61 is rotated to be fastened again, such that the handle 61
pushes against the second support rack 30, and the second support
rack 30 presses against the first support rack 20. Therefore, the
second pillar 63 is engaged in the second groove 64 for adjusting
and fixing the angle included by the second support rack 30 and the
first support rack 20.
[0031] Referring to FIG. 3 and FIG. 8, based on different user
demands, when the user needs to adjust the inclination angle of the
table board 40, the handle 61 is rotated to be loosened.
Subsequently, if the inclination angle of the table board 40 is to
be increased, and the second support rack 30 sways away from the
first support rack 20; if the inclination angle of the table board
40 is to be decreased, the second support rack 30 sways toward the
first support rack 20. Upon the angle between the second support
rack 30 and the first support rack 20 reaching a targeted degree,
the handle 61 is rotated to be fastened again. Therefore, the
inclination angle of the table board 40 is adjusted and fixed.
[0032] Referring to FIG. 3 and FIG. 9, when the user needs to
adjust the height of the table board 40 against the ground, the
handle 51 is rotated to be loosened. When the height of the table
board 40 is to be increased, the first support rack 20 sways away
from the foot 10; when the height of the table board 40 is to be
decreased, the first support rack 20 sways toward the foot 10. Upon
the angle between the first support rack 20 and the foot 10
reaching a targeted degree, the handle 51 is rotated to be fastened
again. Therefore, the height of the table board 40 against the
ground is adjusted and fixed.
[0033] Although particular embodiments of the invention have been
described in detail for purposes of illustration, various
modifications and enhancements may be made without departing from
the spirit and scope of the invention. Accordingly, the invention
is not to be limited except as by the appended claims.
