Abstract
A television stand has a base, a pivotal hinge extension formed on one end of the base and having a cavity defined therein, an extension formed in the base and laterally extending into the cavity, a pivot plate rotatably mounted on the extension with a vertical axis of rotation and a frame pivotally connected to the pivot plate with a lateral axis of rotation. Consequently, the frame can be folded into the base when the television mounted in the frame is not in use. In addition, the frame can be longitudinally rotated relative to the base to adjust the operation angle. The facility and versatility of using the television stand can be improved.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a television stand, and more particularly to a foldable and rotatable television stand for a vehicle.
2. Description of Related Art
A television is mounted in a van to increase passenger enjoyment during a journey. The conventional stand for a television comprises a hollow frame securely attached to the ceiling of a van. However, because the conventional television stand is attached to the ceiling of the van, the conventional television stand will reduce the internal space available in the van. The convenience of getting in or out of the van will be reduced.
In addition, because the conventional television stand is securely mounted in the van, the television mounted in the conventional stand cannot rotate to accommodate the position of the viewer.
To overcome the shortcomings, the present invention tends to provide an improved television stand to mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTION
The main objective of the invention is to provide an improved television stand having a base, a pivotal hinge extension, an extension, a pivot plate and a frame. The pivotal hinge extension integrally formed on the base and having a cavity defined therein. The extension is integrally formed on the base and extends laterally into the cavity. The pivot plate is pivotally mounted on the extension with a longitudinal axle. The frame receives the television and is pivotally connected to the pivot plate with a lateral axis. By such an arrangement, the frame can be rotated parallel with the roof of the van when the television mounted in the frame is not in use. This improves the convenience of the television stand when the television is being used and when it is stored.
The other objective of the invention is to provide an improved television stand. Because the frame is pivotally mounted on the base with a longitudinal axis, the frame can be longitudinally rotated relative to the base. Consequently, the television stand is much more versatile.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
With reference to
FIGS. 1 and 2
, a television stand in accordance with the present invention comprises a base (
10
) and a frame (
20
) pivotally connected to the base (
10
). The base (
10
) can be attached to the ceiling of a vehicle like a van. A recess (
102
) is defined in the bottom of the base (
10
) to receive the frame (
20
). A pivotal hinge extension (
12
) is formed on one end of the base (
10
) and has a substantially Y-shaped cavity (
122
) defined in the bottom. The cavity (
122
) is open to the recess (
102
), and an extension (
14
) formed on the base (
10
) extends into the cavity (
122
).
A flat screen television (
30
) is secured in the frame (
20
). A pivot plate (
22
) is pivotally connected to the frame (
20
) with a lateral axis of rotation. Segments of a hinge tube (
202
,
222
) are formed on both the frame (
20
) and the pivot plate (
22
), and a pivot pin extends through the hinge tube (
202
,
222
) segments so the frame (
20
) is pivotally connected to the pivot plate (
22
). An upper plate (
24
) and a lower plate (
25
) squeeze the extension (
14
) and the pivot plate (
22
). A sleeve (
242
) with an internal threaded hole extends downward from the bottom of the upper plate (
24
) and through the extension (
14
), the pivot plate (
22
) and the lower plate (
25
). The sleeve (
242
) extends through aligned holes (
142
,
224
,
252
) defined in the extension (
14
), pivot plate (
22
) and lower plate (
25
), respectively. A bolt (
26
) screws into the sleeve (
242
), such that the pivot plate (
22
) can be pivotally connected to the extension (
14
) with a vertical axis of rotation. Consequently, the frame (
20
) is pivotally connected to the base (
10
) with two perpendicular axes of rotation.
With reference to
FIGS. 3
to
5
, the base (
10
) is inlaid into the ceiling of a van. If a passenger wants to watch the TV (
30
), he or she pivots the frame (
20
) down relative to the base (
10
) on the lateral axis. The frame (
20
) can be adjusted to a desired angle to face the viewer sitting in the rear seat, such that the viewer can watch the TV (
30
) mounted in the frame (
20
). When the user does not want to watch the TV (
30
). He or she rotates the frame (
20
) into the recess (
102
) of the base (
10
), as shown in
FIG. 2
, so that the television stand is folded into the ceiling. This keeps the passengers from bumping the stand when they get in or out of the van. The convenience of using the television stand is improved.
With reference to
FIGS. 6 and 7
, because the frame (
20
) is pivotally connected to the base (
10
) with a longitudinal axis, the frame (
20
) rotated left or right relative to the base (
10
) to adjust the direction. Consequently, the TV (
30
) can be adjusted to face a viewer sitting near the door of the van. The angle of the frame (
20
) is limited by the inner wall of the cavity (
122
). This improves the versatility of using the television stand.
With reference to FIGS.
1
and
4
-
7
, a curved groove (
146
) is defined in the extension (
14
) with the hole (
142
) as the center of curvature. A pin (
28
) extends through the upper plate (
24
), curved groove (
146
), pivot plate (
22
) and lower plate (
25
) and screws into a nut. When the frame (
20
) rotates laterally relative to the base (
10
) with the sleeve (
242
) as a pivot, the pin (
28
) will slide along the curved groove (
146
), and the rotation angle of the frame (
20
) will be limited by the curved groove (
146
).
Furthermore, a resilient strip (
226
) is formed on the pivot plate (
22
), and a bore (
228
) is defined at the middle point of the strip (
226
). An aperture (
144
) is defined in the extension (
14
) and aligns with the bore (
228
) on the pivot plate (
226
). A positioning block (
27
) made of rubber material is received in the aperture (
144
) and abuts the strip (
226
). A nub (
272
) protrudes from the bottom of the block (
27
) and extends into the bore (
228
), such that the initial point of the frame (
20
) will be held in position by the engagement between the nub (
272
) and bore (
228
).
When the frame (
20
) is rotated relative to the base (
10
), the positioning block (
27
) will press against the resilient strip (
226
), such that the block (
27
) will tightly abut the strip (
226
) to provide a holding effect on the pivot plate (
22
). The frame (
20
) will be securely positioned in any desired angle due to the damping effect provided by the block (
27
).
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
