DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an example of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an overall perspective view of a display device. In this example, the display device is exemplified by a plasma display having a diagonal line length of about 30 to 42 inches, but is not limited to this.
A pair of spacers (3) and (3) are provided on the mounting plate (20) in contact with the floor surface (7) so as to be spaced apart from each other on the left and right. 1) is placed. The mounting plate (20) and the spacers (3) and (3) or the receiving piece (6) described later constitute a support base (2) of the cabinet (1), and the cabinet (1) and the support base (2) Thus, one image display unit is configured.
A speaker box (4) is fitted between the lower surface of the cabinet (1) and the upper surface of the mounting plate (20). As is well known, the front surface of the cabinet (1) forms a display surface (10) for displaying an image, and sound is emitted from the front surface of the speaker box (4).
[0007]
As shown in FIG. 2, the display surface (10) of the plasma display includes a front glass plate (12) with a transparent electrode (14) attached to the back surface, and the front glass plate (12) and the rear glass plate (13). Between these, an inert gas is sealed. The space between the front glass plate (12) and the rear glass plate (13) is partitioned into a large number of cells by the partition walls (15), and the phosphor (16) is applied in the cells. When a voltage is applied to the transparent electrodes (14) and (14) to discharge, ultraviolet rays are generated, whereby the phosphor (16) emits light and an image is displayed. Therefore, it is not necessary to scan the electron beam as in the cathode ray tube system, so that the front and rear thickness can be reduced. That is, although the screen (1) is large and the cabinet (1) is heavy, since the cabinet (1) is thin, it is necessary to stably support the cabinet (1).
[0008]
The support base (2) shown in this example is provided so that the height can be adjusted by removing the spacer (3), and the height of the cabinet (1) can be adjusted to the viewing posture of the viewer.
FIGS. 3A and 3B are a front view and a right side view of the cabinet (1) and the support base (2), respectively. The cabinet (1) has a storage box (11) for storing various electrical components on the rear side of the display surface (10), and the lower surface of the storage box (11) is inclined downward toward the front. . The storage box (11) is placed on the upper surface of the spacer (3), and the cabinet (1) is supported. The upper surface of the spacer (3) forms an inclined surface (31) inclined downward toward the front, and has a shape that fits the lower surface of the storage box (11).
[0009]
The spacer (3) is formed hollow, and a reinforcing wall (30) for receiving the load of the cabinet (1) is provided inside the front end. Since the load of the cabinet (1) is received by the reinforcing wall (30), there is no possibility that the spacer (3) is pushed by the cabinet (1) from above and broken.
The spacer (3) is detachably fitted to a pair of receiving pieces (6) and (6) provided on the mounting plate (20), and the receiving piece (6) can also support the cabinet (1). . The upper surface of the receiving piece (6) also forms an inclined surface (60) inclined downward in the forward direction in accordance with the upper surface of the storage box (11).
4 (a) and 4 (b) are a front view and a right side view of the cabinet (1) and the support base (2), respectively, with the spacer (3) removed. By removing the spacer (3) and the speaker box (4), the cabinet (1) can be lowered by the difference between the height of the spacer (3) and the height of the receiving piece (6). The height of the cabinet (1) can be changed according to the posture. In addition, some viewers do not use the speaker box (4), so the layout of the entire image display unit can be changed according to the viewer's preference.
In addition, several types of spacers (3) having different heights may be prepared and the heights may be changed variously.
[0010]
(Details of mounting structure)
FIG. 5 is an exploded perspective view of the spacer (3) and the mounting plate (20), FIG. 6 is a plan view of the receiving piece (6), and FIG. 7 is a plan view of the spacer (3). It is a perspective view which shows the state attached to.
On the upper surface of the receiving piece (6), a horizontal plane (61) is formed behind the slope (60), and a through hole (62) is formed in the horizontal plane (61). A plate-like fixture (5) extending vertically is fitted into the through hole (62) from above. The fixture (5) is screwed to the rear end surface of the storage box (11) to support the rear end of the cabinet (1) (see FIGS. 3 and 4).
In other words, the front end of the cabinet (1) is supported by the reinforcing wall (30), the rear end is supported by the fixture (5), and is supported at a distance corresponding to the thickness of the cabinet (1). Even if the thickness of the cabinet (1) is thin, the cabinet (1) can be stably supported.
[0011]
In the fixture (5), a plurality of screw through holes (50, 50) are opened up and down, and a screw (not shown) is passed from the rear of the fixture (5) through the screw through hole (50) to the cabinet. (1) Screw onto the rear end face. Since there are multiple screw through holes (50) and (50), the fixture (5) and the cabinet (1) can be screwed even if the height of the cabinet (1) is changed by attaching and detaching the spacer (3). I can stop it. As shown in FIG. 6, a set screw (65) is inserted from the rear side of the receiving piece (6), and passes through the fixture (5) fitted in the rear end surface of the receiving piece (6) and the through hole (62). Then, the nut (64) is screwed onto the tip of the set screw (65), whereby the fixture (5) is held between the nut (64) and the rear end surface of the receiving piece (6), and the receiving piece (6 ).
It should be noted that two or more through holes (62) and (62) may be provided before and after, and the fixture (5) may be selectively fitted into any of the through holes (62) and (62). Since the thickness l of the cabinet (1) (see FIG. 4 (b)) varies depending on the size of the display surface (10), the fitting (5) can be fitted into any of the through holes (62) (62). The cabinet (1) can be attached to the receiving piece (6) or the spacer (3) without changing the front-rear position of the display surface (10).
Moreover, the fixture (5) may be attached to the spacer (3).
[0012]
Two screw holes (66) and (66) are formed in the front and rear of the inclined surface (60) of the receiving piece (6), and the screw holes (66) and (66) are formed in the inclined surface (31) of each spacer (3). ) And a slit (33) are formed. From above the spacer (3), the set screws (34) and (34) are screwed into the screw holes (66) and (66) of the receiving piece (6) through the screw fitting holes (32) and the slits (33). Thus, the spacer (3) can be attached to the receiving piece (6) and the mounting plate (20). The spacer (3) is provided with a transparent window (36) that allows the fixture (5) to pass therethrough.
A notch (35) is formed at the lower end of the inner side surface of the spacer (3), and the inner side surface of the receiving piece (6) is located in the notch (35). The inner side surface of the receiving piece (6) and the inner side surface of the spacer (3) are located in substantially the same plane. If the inner side surface of the receiving piece (6) is covered with the spacer (3) without opening the notch (35), the speaker box is placed between the spacers (3) and (3) as described later. Since (4) is fitted, the distance between the spacers (3) and (3) is increased by the thickness of the inner side surface of the spacer (3). Therefore, a notch (35) is provided on the inner side surface of the spacer (3) in order to reduce the space between the spacers (3) and (3) as much as possible and prevent the mounting plate (20) from becoming large.
[0013]
As shown in FIG. 7, the speaker box (4) is configured by providing a box (41) behind the horizontally long front panel (40), and the box (41) includes both spacers (3) (3). Fit in between. Screw through holes (21) and (21) are opened between the spacers (3) and (3) on the mounting plate (20). From the lower side of the mounting plate (20), set screws (42) ( The speaker box (4) is screwed to the mounting plate (20) by screwing 42) through the screw through holes (21), (21) and the bottom surface of the box (41).
As shown in FIG. 8, when the speaker box (4) is screwed to the mounting plate (20), the front panel (40) hides most of the front surface of the spacer (3). As described above, since the cabinet (1) is placed on the upper surface of the spacer (3), the spacer (3) is hidden behind the cabinet (1) and the speaker box (4) as shown in FIG. Since only a small part can be seen or hidden, the appearance is improved.
[0014]
Since the load of the cabinet (1) is received by the reinforcing wall (30), the spacer (3) is not damaged even if the load of the cabinet (1) is heavy. Further, the cabinet (1) is supported by the reinforcing wall (30) at the front end and the fixture (5) at the rear end, and is supported at a distance corresponding to the thickness of the cabinet (1). 1) can be stably supported. Furthermore, since the spacer (3) is provided with a reinforcing wall (30), even if the cabinet (1) is placed on the upper surface of the spacer (3) when the spacer (3) is high, it is resistant to buckling, etc. The effect of can be considered.
In addition, as shown in FIG. 9, when the lower surface of the storage box (11) of the cabinet (1) is inclined downward toward the rear, the reinforcing wall (30) is placed on the inner rear end of the spacer (3). The mounting tool (5) may be provided at the front end of the spacer (3). Even in this case, the cabinet (1) is stably attached with the front and rear ends supported by the reinforcing wall (30) and the fixture (5).
