Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention generally relates to a supporting
device and, in particular to a lifting support device for lifting a
panel.
[0003] 2. Description of Prior Art
[0004] The touch panels are widely used in various places by people
with a progress and maturity of the touch panel technology, such as
navigation systems in exhibitions or personal displays in a
conference room.
[0005] In operation, the panel is usually required to fix at a
certain height for providing feasible view for user. However, the
panels are mostly fixed on a wall or assembled on a supporter or
embedded in a desk that users cannot adjust the height of the panel
as demands.
[0006] Moreover, few panel supporters that can be adjusted to get a
required height by manual adjustment of the fixed location of a
telescopic rod. However, such adjustment is time-consuming and
laborious. Besides, a fixed position of a telescopic rod is usually
located below the panel, and users need to squat aside the panel
support to adjust the height of the panel. Therefore that is
inconvenient for users.
[0007] In view of the above drawbacks, the Inventor proposes the
present invention based on his expert knowledge and elaborate
researches in order to solve the problems of prior art.
SUMMARY OF THE INVENTION
[0008] Accordingly, an object of the present invention is to
provide a lifting support structure, in which the object which
linked with the first end of the movable rod will be moved with the
actuating element for lifting.
[0009] In order to achieve the object mentioned above, the present
invention provides a lifting support structure including an
actuating element, a bearing seat, a connecting rod and a pedal.
The actuating element includes a cylinder and a movable rod moved
reciprocally in the cylinder. The movable rod has a first end and a
second end disposed oppositely. The bearing seat is disposed on a
lateral side of the actuating element, and second end of the
movable rod is inserted in the bearing seat. The connecting rod is
pivoted on the bearing seat and can pivot in a horizontal direction
relative to the bearing seat. The connecting rod has a fix end and
a free end disposed oppositely. The fix end is connected with the
second end of the movable rod, and the free end is suspended
freely. The pedal is connected on the free end of the connecting
rod.
[0010] Comparing to the prior art, the lifting support structure of
the present invention includes an actuating element, a bearing
seat, a connecting rod and a pedal. When users exert on an end the
pedal, the pedal will bring the connecting rod pivoted on the
bearing seat to move together, and the connecting rod will move
along with the actuating element in a longitudinal direction.
Similarly, force exerted on the other end of the pedal will make
the actuating element moving in another direction. Therefore, the
actuating element can bring the linked object moving upward or
downward to get to a location where the object needed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0020] In cooperation with attached drawings, the technical
contents and detailed description of the invention are described
thereinafter according to a number of preferable embodiments, being
not used to limit its executing scope. Any equivalent variation and
modification made according to appended claims is all covered by
the claims claimed by the present invention.
[0021] Please refer to FIG. 1 to FIG. 3, they depict a perspective
schematic view of a lifting support structure, a perspective
exploded view of a lifting support structure and an assembled view
of the actuating element of the present invention. The lifting
support structure 1 comprises an actuating element 10, a bearing
seat 20, a connecting rod 30 and a pedal 40. The bearing seat 20 is
provided for connecting the actuating element 10 and the connecting
rod 30, and the pedal 40 is connected with the connecting rod 30.
The connecting rod 30 is moved with the actuating element 10 after
an external force is exerted on, and then the actuating element 10
has a linear movement.
[0022] The actuating element 10 is, but not limited to, a gas
cylinder, a hydraulic cylinder or a lift cylinder having a
restoring force. The actuating element 10 includes a cylinder 11
and a movable rod 12 moved reciprocally in the cylinder 11. The
movable rod 12 has a first end 121 and a second end 122 disposed
oppositely, and the first end 121 is connected with an object. In
the present embodiment, the object is a table 2, and a panel 2 is
disposed on the table 2. The lifting support structure 1 of the
present invention can bring the table and the panel 3 moving upward
or downward and can be positioned at a certain height to meet
user's requirement.
[0023] In an embodiment of the present invention, the lifting
support structure 1 further includes a control box 50, a platform
60 and a plural of rollers 61 provided on the bottom of the
platform 60. The actuating element 10 and the bearing seat 20 are
disposed on the control box 50. One end of the connecting rod 30 is
protruded out of the control box 50, and the pedal 40 is located at
a lateral side outside the control box 50. Furthermore, the control
box 50 is installed on the platform 60, and the lifting support
structure 1 can be easily moved to other places by the platform 60
with the rollers 61.
[0024] As shown in FIG. 2 and FIG. 3, the bearing seat 20 is
disposed on a lateral side of the actuating element 10, and second
end 122 of the movable rod 12 is inserted in the bearing seat 20.
Besides, the connecting rod 30 is pivoted on the bearing seat 20 so
that it can pivot in a horizontal direction relative to the bearing
seat 20. The connecting rod 30 has a fix end 31 and a free end 32
disposed oppositely. The fix end 31 is connected with the second
end 122 of the movable rod 12, and the free end 32 is suspended
freely. Moreover, the pedal 40 is connected on the free end 32 of
the connecting rod 30. More details of the configurations are
described as following.
[0025] In an embodiment of the present invention, the bearing seat
20 has a U-shaped frame plate 21 and a pair of pivoting arms 22
extending from the U-shaped frame plate 21. The second end 122 of
the movable rod 12 is inserted in the U-shaped frame plate 21, and
the fix end 31 of the connecting rod 30 is inserted through the
pair of the pivoting arms 22 therebetween for connecting with the
second end 122 of the movable rod 12.
[0026] Preferably, the U-shaped frame plate 21 has a through hole
210 for inserting the second end 122 of the movable rod 12 and a
trough 211 for inserting the fixed end 31 of the connecting rod 30.
The through hole 210 and the trough 211 are located on two adjacent
sides of the U-shaped frame plate 21.
[0027] Please further refer to FIG. 4 to FIG. 6, they depict a side
view of a lifting support structure and partial assembly cross
sectional views of two sides of the actuating element. The lifting
support structure 1 of the present invention further includes a
hollow pillar 70, and the actuating element 10 is disposed in the
hollow pillar 70. The movable rod 12 can move a distance upward or
downward along a longitudinal direction 70 of the hollow pillar
70.
[0028] Please also refer to FIG. 7 and FIG. 7, they depict an
operating schematic view and an application view of a lifting
support structure of the present invention. The lifting support
structure 1 of the present invention is provided for a user to
stamp on the pedal 40. When the pedal is stamped downward, the
connecting rod 30 pivoted on the bearing seat 20 will be linked for
moving together. Then the fix end 31 of the connecting rod 30 will
move upward and the second end 122 of the movable rod 12 will be
pushed simultaneously. The movable rod 12 will move in a
longitudinal direction 70 of the cylinder 11 and the hollow pillar
70, thus the first end 122 of the movable rod 12 will be moved
upward.
[0029] As shown in FIG. 8, when the first end 122 of the movable
rod 12 is moved upward, the table 2 linked with the first end 122
of the movable rod 12 will be moved together. Therefore, the panel
3 disposed in the table 2 will be moved together with the table 2.
In this way, the table 2 and the panel 3 can be moved upward or
downward through the lifting support structure 1 of the present
invention and located at a certain height which users required.
[0030] Although the present invention has been described with
reference to the preferred embodiment thereof, it will be
understood that the invention is not limited to the details
thereof. Various substitutions and improvements have been suggested
in the foregoing description, and others will occur to those of
ordinary skill in the art. Therefore, all such substitutions and
improvements are intended to be embraced within the scope of the
invention as defined in the appended claims.
