The present application is related to the Japanese Utility Model Application No. 2005-6952, filed Aug. 25, 2005, the entire disclosure of which is expressly incorporated by reference herein.
(1) Field of the Invention
The present invention relates to an LCD television having a stand that supports the body of the LCD television from underneath via a body-side bracket, by extending a support bracket fixed to the body-side bracket.
(2) Description of Related Art
The LCD television disclosed in Japanese Patent Laid-open Publication (JP-A) No. 15542/2003 requires that the stand be detached to remove the rear case, making it impossible to stand the LCD television upright with the rear case removed.
With the plasma display apparatus disclosed in JP-A No. 126456/2004, it is necessary to detach the stand unit to remove the back cover, making it impossible to stand the plasma display apparatus upright with the back cover removed.
Japanese Patent Application No. 3599332 discloses an LCD display unit that stands upright with its back cabinet removed. In this document, an LCD display unit is described that comprises: a display unit having an LCD panel at the front; a display section including a front cabinet having a display window for the LCD panel and a back cabinet, and containing the display unit; and a stand that supports the display section, wherein: an extended mounting bracket is provided at a lower portion of the display unit; a support bracket is equipped to fix the stand to the mounting bracket; the support bracket and the mounting bracket are fixed by means of fixing screws, with the support bracket at back and the mounting bracket in front; at least the mounting bracket is covered with the back cabinet; and an opening is formed in the back cabinet to allow the above-described fixing members to pass through the back cabinet.
As illustrated in
According to the art described in Japanese Patent Application No. 3599332, the pair of guide rails on the mounting bracket simply constrains the support bracket so that it will not move left or right. Therefore, the support bracket is designed to be easily disengaged backward from the pair of guide rails.
Also, the raised portion of the mounting bracket simply constrains the support bracket so that it will not move upward. Therefore, the support bracket is designed to easily come off backward from the raised portion
Accordingly, it is necessary to fix the support bracket to the mounting bracket with four or more fixing screws. Because, if the fixing screws are removed, the support bracket comes off, toward the back, the pair of guide rails on the mounting bracket and the raised portion. This results in the following problems:
(A) It is impossible to detach the stand by removing the fixing screws with the LCD display unit standing upright. As a result, it is necessary to lay the LCD display unit sideways and remove the fixing screws to detach the stand, when using the LCD display unit as a wall-hanging display unit.
(B) Since many, four or more, fixing screw are required to fix together the support bracket and mounting bracket, material cost becomes high in manufacturing the LCD display unit, and also assembling the support bracket and mounting bracket requires much labor, resulting in high manufacturing cost of the LCD display unit.
(C) Since the support bracket is guided by the guide rails, a slight deformation of the support bracket or mounting bracket may increase friction resistance excessively, making it impossible to insert the support bracket in the mounting bracket.
The art described in Japanese Utility Model Publication No. 4143/1993 is for personal computers, and cannot be applied to LCD televisions. In this art, since a connector projects downward from the lower surface of a display unit, a good appearance may not be obtained when the display unit is hung on a wall, and also the display unit does not stand upright by itself.
The present invention discloses an LCD television wherein it is possible to stand a body upright by supporting it with a stand even when a rear cabinet is removed, and the stand can be detached to enable the body to be hung on a wall or to make the body alone stand upright, and it is also possible to use no or fewer screws to fix a support bracket to a body-side bracket, thereby reducing the manufacturing cost.
One aspect of the present invention provides an LCD television that comprises: a body having a cabinet that is composed of a front cabinet having an LCD panel formed at its front as a display window and a rear cabinet to be mounted at the back of the front cabinet; a body-side bracket attached to the body; and a stand that supports the body from underneath via the body-side bracket by extending upward a support bracket to be fixed to the body-side bracket, wherein: the support bracket is formed in the shape of plate; a bracket insertion slot is formed on the underside of the cabinet to insert the support bracket upward between the front cabinet and rear cabinet; the body-side bracket comprises a lower holding portion that retains the support bracket slidably up and down, with both horizontal edges of the support bracket inserted upward; an upper holding portion that retains the support bracket with its upper edge portion inserted upward; and a stopper portion to constrain upward movements of the support bracket inserted in the upper holding portion, and is mounted on the front cabinet above the bracket insertion slot and fixed by inserting the support bracket, which has been inserted in the bracket insertion slot from underneath, in the lower holding portion from underneath and sliding the support bracket up and down to insert it in the upper holding portion.
Another aspect of the present invention provides a bracket insertion slot may be formed on the underside of the front cabinet.
When the support bracket is inserted upward in the bracket insertion slot from underneath with the rear cabinet mounted to the front cabinet, the both horizontal edges of the support bracket are inserted upward in the lower holding portion from underneath, and then the upper edge of the support bracket is inserted upward in the upper holding portion from underneath, upward movements of the upper edge of the support bracket are constrained by the stopper portion. At this time, both horizontal edges of the support bracket are retained at the lower holding portion and the upper edge of the support bracket is retained at the upper holding portion. As a result, the support bracket is fixed to the body-side bracket and the body is supported from underneath by the stand via the body-side bracket.
Here, the support bracket is fixed to the body-side bracket without using screws, and therefore when the LCD television is lifted with it standing upright, the support bracket comes off downward by itself and the stand is detached. This makes it possible to detach the stand easily and use the LCD television as a wall-hanging television without removing the rear cabinet. Also, since the support bracket is inserted in a body side bracket insertion slot, no downward projections from the bottom of the body are necessary. This allows the body alone to stand upright without the stand.
Since the support bracket is mounted on the front cabinet, it is needless to say that the body stands upright supported by the stand even if the rear cabinet is removed, thereby improving the convenience in developing LCD televisions.
Furthermore, since it is not necessary to use many screws for fixing the support bracket to the body-side bracket, it is possible to eliminate or reduce fixing screws and bosses, reduce the material cost for manufacturing LCD televisions, and ease the work for assembling the support bracket and the body-side bracket, thereby reducing the manufacturing cost of LCD televisions.
Also, since the support bracket is retained by both the lower holding portion and the upper holding portion, some distortions in the support bracket and/or body-side will not prevent the support bracket from being inserted in the body-side bracket for fixing.
According to an aspect of the present invention, it is possible to stand the body upright even when the rear cabinet is removed, use the body as a wall-hanging television or stand the body alone upright by detaching the stand without removing the rear cabinet, and eliminate or reduce the screws for fixing the support bracket to the body-side bracket and thereby to reduce the manufacturing cost. Also, it is possible to fix the body-side bracket while securely retaining and positioning the support bracket by the upper holding portion, and thereby to support the body with the stand in a more stable condition. Since the body tilts, improved convenience can be achieved.
According to another aspect of the present invention, it is possible to stand the body upright even when the rear cabinet is removed, detach the stand without removing the rear cabinet to use the body as a wall-hanging television or stand the body alone upright, and also eliminate or reduce the screws for fixing the support bracket to the body-side bracket to reduce the manufacturing cost.
According to an optional aspect of the present invention, the support bracket can be securely retained by the lower holding portion and fixed to the body-side bracket.
According to another optional aspect of the present invention, the support bracket can be fixed to the body-side bracket while securely retaining and positioning the support bracket with the upper holding portion.
According to another optional aspect of the present invention, the support bracket can be fixed to the body-side bracket while more securely retaining and positioning the support bracket with the upper holding portion.
According to another optional aspect of the present invention, the body-side bracket is firmly fixed and therefore it is possible to fix the support bracket while more securely retaining and positioning the support bracket with the lower holding portion and the upper holding portion.
According to another optional aspect of the present invention, the support bracket is firmly fixed and therefore the body can be supported by the stand in more stable condition.
According to another optional aspect of the present invention, it is possible to fix the body-side bracket while more securely retaining and positioning the support bracket with the upper holding portion.
According to another optional aspect of the present invention, the body tilts and therefore improved convenience can be achieved.
These and other features, aspects, and advantages of the invention will be apparent to those skilled in the art from the following detailed description of preferred non-limiting exemplary embodiments, taken together with the drawings and the claims that follow.

The detailed description set forth below in connection with the appended drawings is intended as a description of presently preferred embodiments of the invention and is not intended to represent the only forms in which the present invention may be constructed and or utilized.
The embodiments of the present invention are described below in the following order:
(1) Description of an LCD television
(2) Advantages of the LCD television
(3) Modifications
(1) Description of an LCD Television:
First, the TV 100 is briefly described.
The TV 100 roughly comprises a body 10, a body-side metallic bracket 20 mounted on the body, and a stand 30 that supports the body 10 from underneath via the body-side bracket. The body 10 comprises an approximately box-typed thin cabinet 12, an LCD panel 16 contained in the cabinet 12 with its picture displaying LCD display surface facing forward, a metallic panel support plate 17 that is attached to a front cabinet 13 in the cabinet 12 to support the LCD panel 16, a printed circuit board 18 on which a control circuit is formed, a receiver section (not shown) to receive broadcast signals, and an audio output section (not shown) to output voices. The panel support plate 17 is a frame member produced by press-forming a metal plate, having a pair of through holes 17a for screws arranged from side to side on a lower portion, and is fixed to an inner surface of the front of the front cabinet 13 with plural screws 51. The control circuit causes broadcast signals to be received and signals in a predetermined format to be input from an external input terminal, and thereby displays pictures on the LCD display surface and outputs voices from the audio output section.
The cabinet 12 comprises the front cabinet 13 made of plastic and having a display window 13a of the LCD panel 16 formed at the front, and a rear cabinet 14 made of plastic and to be mounted on the back of the front cabinet. The front cabinet 13 has four cabinet-mounting bosses 13b, four panel support-mounting bosses for fixing the panel support plate, and the like, all of them projecting backward, and is integrally formed by injection molding of thermoplastic resin or the like. The rear cabinet 14 has four cabinet fixing holes 14a, four wall-hanging screw holes 14g, and the like, formed on its back, and is integrally formed by injection molding of thermoplastic resin or the like.
The stand 30 supports the body 10 from underneath via the body-side bracket 20, by extending upward the metallic support bracket 40 to be fixed to the body-side bracket 20. The support bracket 40 is a plate-like member integrally formed by press-forming a metal plate.
At the bottom of the cabinet 12, a bracket insertion slot 15 is formed, through which the support bracket 40 is inserted upward between the front cabinet 13 and rear cabinet 14. This bracket insertion slot is formed between the front cabinet and rear cabinet by cutting off a portion of the front cabinet.
As shown in
When the support bracket 40 is inserted upward in the bracket insertion slot 15 from underneath with the rear cabinet 14 mounted on the front cabinet 13, both horizontal edges 40c and 40d of the support bracket 40 are inserted upward in the lower holding portions 22 and 23 of the body-side bracket 20 from underneath, and the upper edge of the support bracket 40 is inserted upward in the upper holding portions 24 and 25 from underneath, upward movements of the upper edge of the support bracket 40 is constrained by the stopper portion 26. At this time, both horizontal edges 40c and 40d of the support bracket 40 are retained at the lower holding portions 22 and 23, and the upper edge of the support bracket 40 is retained at the upper holding portions 24 and 25. This causes the support bracket 40 to be fixed to the body-side bracket 20, and the body to be supported by the stand 30 from underneath via the body-side bracket 20.
Here, as shown in
Needless to say, since the support bracket 40 is mounted on the front cabinet 13, the body stands upright with the support of the stand 30 even when the rear cabinet 14 is removed, thus improving the convenience in development of LCD televisions.
Moreover, since it is possible to eliminate or reduce the screws or bosses for fixing the support bracket 40 to the body-side bracket 20, material cost in manufacturing LCD televisions can be reduced and also the work for assembling the support bracket 40 with the body-side bracket 20 can be eased, making it possible to reduce the cost of manufacturing LCD televisions.
Next, the TV 100 is described in detail.
As shown in
This allows the body 10 to be tiltably supported by the stand 30 about the rotation axis L1, via the body-side bracket 20. Since this enables a user of an LCD television to retain the LCD display surface at a desired angle by tilting it, this LCD television is convenient.
In addition, the stand base is metallic and the TV 100 is grounded though the panel support plate 17, body-side bracket 20, support bracket 40, and stand base 34, and in this regard the TV 100 is of rational construction.
As shown in
On the bent extending portion 21a, the upper holding portions 24 and 25 that are through holes for inserting the upper insertion portions 44 and 45 of the support bracket 40, and the stopper portion 26 for constraining upward movements of the support bracket inserted in the upper holding portions 24 and 25 that are through holes by hitting a stopper hitting portion 42 of the support bracket 40 against the bottom are formed. The second bent extending portion 21b brings the first and second upper insertion portions 44 and 45 in contact with the front opposite to the rear surface where the support bracket 40 is fixed.
The lower holding portions 22 and 23 each comprises the first lower holding portion 22 on the left side that causes the left edge 40c of the support bracket to be inserted upward to make it slidable up and down, and the second lower holding portion 23 on the right that causes the right edge 40d to be inserted upward to make it slidable up and down. The first and second lower holding portions 22 and 23 have lower holding bases 22a and 23a extending from the rear of the main portion 21 to which the support bracket 40 is fixed to the support bracket 40 side (rear side), and adjacent direction extending portions 22c and 23c that extend in directions adjacent to each other from the ends of the extending lower holding bases 22a and 23a and make the support bracket slidable up and down by sandwiching each of the horizontal edges 40c and 40d with the main portion 21. Here, the interval x2 between the inner end (right end) of the first lower holding base 22a and the inner end (left end) of the second lower holding base 23a is made to be slightly larger than the width t2 of the support bracket 40 (for example, t2<x2<1.05×t2). On the other hand, the interval x3 between the inner end (right end) of the first adjacent direction extending portion 22c and the inner end (left end) of the second adjacent direction extending portion 23c is made to be slightly larger than the width t2 of the support bracket (for example, 0.95t2<x3<t2). Also, the interval x4 between the rear of the main portion 21 (front side) and the front end of the adjacent direction extending portions 22c and 23c (rear side) is made to be slightly larger than the thickness t1 of the support bracket (for example t1<x4<2×t1).
The upper holding portion 24 and 25 as through holes comprise the first upper holding portion 24 and the second upper holding portion 25 that insert upward the first and second upper insertion portions 44 and 45 respectively and retain them so as to be slidable up and down. The upper holding portions 24 and 25 are formed at the outside of both horizontal edges of the stopper portion 26. Here, the horizontal length x5 of the upper holding portions 24, and 25 is made to be slightly larger than the horizontal length t3 of the upper insertion portions 44 and 45 of the support bracket (for example, t3<x5<2×t3). Also, the cross-directional thickness x6 of the upper holding portions 24 and 25 is made to be slightly larger than the cross-directional thickness t4 of the upper insertion portions 44 and 45 of the support bracket (for example, t4<x6<2×t4). Further, the upper holding portions 24 and 25 are arranged so that the upper insertion portions 44 and 45 of the support bracket are smoothly inserted.
As shown in
On the rear side of the support bracket 40, a pair of evaginated portions 48 are formed that evaginate backward from longitudinal direction to vertical direction. Thanks to this, if an attempt to insert a back-to-front support bracket 40 is prevented by the evaginated portions 48, thus preventing the stand 30 from being attached back-to-front to the body 10.
By providing the lower holding portion, upper holding portion, and stopper portion on the body-sided bracket 20, the support bracket 40 is positioned and fixed to the body-side bracket 20 without being screwed, and the body 10 is securely supported by the stand 30 via the body-side bracket 20. This eliminates or reduce the screws to fixing the support bracket to the body-side bracket.
As shown in
On the panel support plate 17 attached to the front cabinet 13, a pair of panel screwing through holes 17a are formed to screw the body-side bracket 20 alone.
On the body-side bracket 20, a pair of lower screwing through holes 27 corresponding to the screwing bosses 13c are formed, and a pair of upper screwing through holes 28 corresponding to the panel screwing through holes 17a. When a screw 52 is passed through the lower screwing through hole 27 to screw onto the screwing boss 13c, the body-side bracket is directly mounted and fixed to the front cabinet 13, and when the screw 52 is passed through the upper screwing through hole 28 to screw to the panel screwing through hole 17a, the body-side bracket is mounted and fixed to the panel support plate 17.
As described above, the body-side bracket 20 is screwed to the front cabinet 13 made of plastic at two points on the lower portion of the bracket, and screwed to the panel support plate made of robust metal at two points on the upper portion of the bracket. This allows the body-side bracket to be firmly fixed and the support bracket to be fixed to the body-side bracket while securely retaining the support bracket with the lower holding portion and upper holding portion for positioning.
Also, the front cabinet 13 has a pair of both-bracket fixing bosses 13e that are integrally molded at more inner side than the pair of screwing bosses 13c to screw only the body-side bracket 20. The both-bracket fixing bosses 13e are formed side by side and are projecting backward from the inner side of the front of a lower portion of the panel support plate 17.
On the body-side bracket 20, a pair of body-side lower screwing through holes 29 are formed that are integrally molded so as to align with the both-bracket fixing bosses 13e.
The support bracket 40 has a pair of vertically long oval-shaped stand-side lower screwing through holes 46, aligned with the both-bracket fixing bosses 13e.
On the other hand, as shown in
As described above, the support bracket 40 is, after inserted in the body-side bracket 20 and positioned, fixed with screws to the body-side bracket 20 and the front cabinet 13 at the stand-side lower screwing through holes 46. This allows the support bracket to be securely fixed and the body to be supported with the stand in a more stable condition.
Now the assembling procedure for the TV 100 is described below.
First, the body-side bracket 20 is attached to the front cabinet 13 as illustrated in
Next, the stand 30 having the support bracket is attached to the body-side bracket 20 mounted on the body 10, as shown in
There is no need to screw both brackets 40 and 20 at this stage.
Then, the rear cabinet 14 is mounted to the front cabinet 13 as shown in
If both brackets 46 and 29 have not been fixed together with screws, it is possible to screw them to the both-bracket fixing bosses 13e by inserting screws 53 from the both-brackets fixing holes 14e and pass them through the stand-side lower screwing through holes 46 and the body-side lower screwing through holes 29.
(2) Advantages of the LCD Television:
The lower holding portions 22 and 23 and the upper holding portions 24 and 25 for retaining the support bracket 40 constrain cross-directional movements as well as lateral movements of the support bracket. This prevents the support bracket 40 from coming off the body-side bracket backward even if both brackets 40 and 20 have not been screwed together. Since the support bracket 40 is fixed to the body-side bracket 20 without fastening with screws, as just described, it is possible to remove the support bracket 40 by turning the screws 53 from the both-brackets fixing holes 14e. When the TV 100 is lifted with it standing upright, the support bracket comes off downward by itself and the stand is detached. Thus, it is possible to remove the stand easily without removing the rear cabinet for using the LCD television as a wall-hanging television.
Moreover, since the support bracket is inserted in the body side bracket insertion slot, no downward projecting portions from the bottom of the body are needed. This makes it possible to stand the body upright without the stand.
Since the support bracket is mounted on the front cabinet, it is needless to say that the body stands upright with the support of the stand when the rear cabinet is removed, thus improving convenience in developing LCD televisions.
Also, there is no need to use many screws for fixing the support bracket to the body-side bracket, and therefore it is possible to eliminate or reduce the fixing screws and bosses. This reduces the material cost if manufacturing LCD televisions, and also eases the work for assembling the support bracket and the body-side bracket, thus reducing the manufacturing cost of LCD televisions.
Moreover, since the support bracket is retained by the lower holding portion and the upper holding portion, some distortions in the support bracket and/or body-side bracket will not prevent inserting the support bracket in the body-side bracket to fix.
(3) Modifications:
According to the present invention, various modifications are conceivable.
Although small to medium sized LCD televisions with 25 inch or less screen are preferable because such television are light and easy to tilt, medium to large sized ones may be applicable. Also, LCD televisions having integral video decks or DVD players are also applicable. The present invention is also applicable to LCD televisions equipped with a swivel mechanism and LCD televisions without a tilt mechanism.
The upper holding portions formed on the body-side bracket may be reduced to one, and also the upper insertion portion may be reduced to one. The stopper portion formed on the body-side bracket may be more than one, and also the stopper hitting portion formed on the support bracket may be more than one. For example, it is possible to form a single upper holding portion at a horizontal central portion of the upper side of the body-side bracket, and a stopper portion on both horizontal outsides of the upper holding portion, and form a single insertion portion at a horizontal central position on the upper edge of the support bracket and a stopper hitting portion on both horizontal outsides of the upper insertion portion.
The bracket insertion slot may be formed between front cabinet and rear cabinet by cutting off a portion of the rear cabinet.
Also, as shown in
Even various modifications described above have the same advantages, namely, the body can stand upright with the stand even when the rear cabinet is removed, the body can be used as a wall-hanging television or can stand upright without removing the rear cabinet, and the manufacturing cost can be reduced by eliminating or reducing the screws for fixing the support bracket to the body-side bracket.
Although the invention has been described in considerable detail in language specific to structural features and or method acts, it is to be understood that the invention defined in the appended claims is not necessarily limited to the specific features or acts described. Rather, the specific features and acts are disclosed as preferred forms of implementing the claimed invention. Therefore, while exemplary illustrative embodiments of the invention have been described, numerous variations and alternative embodiments will occur to those skilled in the art. Such variations and alternate embodiments are contemplated, and can be made without departing from the spirit and scope of the invention.
