ABSTRACT:
CROSS REFERENCE TO RELATED APPLICATION
This application claims priority of Taiwan Application No. 91211834, filed on Jan. 8, 2002.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a mounting device, more particularly to a mounting device for a display.
2. Description of the Related Art
FIG. 1
shows a conventional mounting device for a display, and generally includes a stationary base
91
, a display-supporting mechanism
9
, and two torsion springs
94
.
As illustrated, the stationary base
91
is mounted on a horizontally extending support
90
, and is formed with opposite lower left and right pivot plates
92
. The display-supporting mechanism
9
includes a bracket
99
, and parallel first and second arm units
95
,
97
. The bracket
99
is disposed above the stationary base
91
for mounting of a display (not shown) thereon, and is formed with opposite upper left and right pivot plates
981
that are disposed above and that are aligned with the lower left and right pivot plates
92
, respectively. The first arm unit
95
includes parallel left and right arms
95
″ which are pivoted to the lower left and right pivot plates
92
about an upper pivot shaft
93
″, and the upper left and right pivot plates
981
. The second arm unit
97
includes parallel left and right arms
97
″, which are pivoted to the lower left and right pivot plates
92
about a lower pivot shaft
93
, and the upper left and right pivot plates
981
in such a manner that the left and right arms
95
″,
97
″ of the first and second arm units
95
,
97
are rotatable relative to the stationary base
91
between upper and lower positions. An adjacent pair of the left arms
95
″,
97
″ of the first and second arm units
95
,
97
is spaced apart from each other by a gap (G). Each of the two torsion springs
94
is sleeved around a respective one of the pivot shafts
93
,
93
″, and has an intermediate section
941
biasing against the stationary base
91
, and two opposite ends
942
secured respectively to two spring-holding elements
70
sleeved firmly on the pivot shafts
93
,
93
″.
Under this condition, rotation of the first and second arm units
95
,
97
relative to the stationary base
91
from the upper position to the lower position results in widening of the gap (G) between the first and second arm units
95
,
97
, which, in turn, results in deformation of the torsion springs
94
, thereby storing a restoring force in the torsion springs
94
to urge the first and second arm units
95
,
97
in a direction from the lower position to the upper position.
The aforesaid conventional mounting device is disadvantageous in that it requires the upper and lower pivot shafts
93
″,
93
and four spring-holding elements
70
for mounting of the torsion springs
94
. In addition, mounting of the torsion springs
94
and the spring-holding elements
70
on the pivot shafts
93
″,
93
is relatively inconvenient.
SUMMARY OF THE INVENTION
Therefore, the object of this invention is to provide a mounting device for a display, which includes less components and which requires little assembly time so as to overcome the aforesaid disadvantages of the prior art.
A mounting device for a display according to the present invention includes a stationary bases a display-supporting mechanism, and an urging unit. The display-supporting mechanism extends upwardly from and is pivoted to the stationary base so as to be rotatable relative to the stationary base between upper and lower positions. The display-supporting mechanism includes a bracket that is disposed above the stationary base, and parallel first and second arm units that extend between and that are pivoted to the stationary base and the bracket and that cooperatively define a gap therebetween. The urging unit is disposed between the stationary base and the bracket, and is connected to the first and second arm units in such a manner that rotation of the display-supporting mechanism relative to the stationary base from the upper position to the lower position results in widening of the gap between the first and second arm units, which, in turn, results in deformation of the urging member, thereby storing a restoring force in the urging unit to urge the display-supporting mechanism in a direction from the lower position to the upper position.
