Description

  The present invention relates to a wall-mounted display device in which a plate-like wall hanging bracket is provided on the outer surface (back surface) of a rear cabinet. This is particularly the case when a chassis bracket that is fixed to a display panel such as a liquid crystal display and forms a skeleton structure is used for a longitudinal frame as a reinforcing member used to prevent deformation of a rear cabinet made of a resin molded body. However, even when a reinforced frame that is not fixed to a display panel such as a liquid crystal display is used, the above-mentioned wall-hanging type that has taken measures to make it possible to select and use the chassis bracket and the reinforced frame without any inconvenience The present invention relates to a display device.

  14 and 15 are longitudinal sectional views illustrating the reinforcing structure of the rear cabinet in the wall-mounted display device as a premise of the present invention. FIG. 14 shows the above-described chassis bracket, and FIG. Each using a reinforcing frame is shown. FIG. 16 is a front view of the wall hanging bracket.

  The wall-mounted display device shown in FIGS. 14 and 15 includes a wall-mounted television receiver that employs, for example, a liquid crystal display or a plasma display, and other wall-mounted display devices. In these wall-mounted display devices, a general cabinet 10 is formed in a flat box shape whose front surface is opened by combining a front cabinet 11 and a rear cabinet 15 together, and an outer surface of the rear cabinet 15 ( A plate-like wall mounting bracket 20 is provided on the back surface. As shown in FIG. 16, the wall-hanging metal fitting 20 has screw insertion holes 21 at its four corners. Such a wall-hanging bracket 20 is used, for example, for hooking and holding a wall-mounted display device on a hook (not shown) mounted on the wall surface of a house. In order to reduce down, it is advantageous to use a standard product (off-the-shelf product) for the wall mounting bracket.

  Incidentally, the chassis bracket 30 shown in FIG. 14 is fixed to a display panel 100 such as a liquid crystal display or a plasma display whose back is covered by the rear cabinet 15 by an appropriate means such as a screw fixing structure 110, and itself. It plays a role as a skeleton structure of the display panel 100. On the other hand, the reinforcing frame 40 shown in FIG. 15 is not fixed to the display panel 100. The chassis bracket 30 and the reinforcing frame 40 correspond to the vertically long frame F that functions as a reinforcing member that prevents the rear cabinet 15 from being deformed as described at the beginning.

  On the other hand, in the structure in which the wall hanging bracket 20 which is a standard product is mounted on the rear cabinet 15, the wall hanging type display device employs the chassis bracket 30 shown in FIG. 14 or the reinforcing frame 40 shown in FIG. The same structure is adopted regardless of whether or not.

  That is, in the wall-mounted display device that employs the chassis bracket 30 of FIG. 14 as the vertically long frame F for reinforcing the rear cabinet 15, the rear cabinet 15 is used as a measure for fixing the wall-hanging bracket 20 to the rear cabinet 15. Screw insertion holes provided at a plurality of locations of the wall hanging bracket 20 and the rear cabinet 15 in a state of being sandwiched between the chassis bracket 30 superimposed on the inner surface and the wall hanging bracket 20 provided on the outer surface side. Mounting screws 200 are inserted through (not shown), and these mounting screws 200 are screwed into screw holes (not shown) of the chassis bracket 30 and tightened. Similarly, in the wall-mounted display device that employs the reinforcing frame 40 of FIG. 15 as the vertically long frame F for reinforcing the rear cabinet 15, as a countermeasure for fixing the wall-hanging bracket 20 to the rear cabinet 15, The cabinet 15 is opened at a plurality of locations of the wall hanging bracket 20 and the rear cabinet 15 in a state where the cabinet 15 is sandwiched between the reinforcing frame 40 superimposed on the inner surface of the cabinet 15 and the wall hanging bracket 20 disposed on the outer surface thereof. Mounting screws 200 are inserted into screw insertion holes (not shown), and these mounting screws 200 are screwed into screw holes (not shown) of the reinforcing frame 40 and tightened.

  On the other hand, the wall-mounted display device of FIG. 14 and the wall-mounted display device of FIG. 15 are different in the work process when the wall-mounted metal fitting 20 is fixed to the rear cabinet 15. That is, in the wall-mounted display device of FIG. 14, the chassis bracket 30 is fixed to the display panel 100 in the previous process in advance, so if the display panel 100 is attached to the front cabinet 11, the front cabinet 11 is attached to the rear cabinet. The chassis bracket 30 is overlapped at a predetermined position on the inner surface of the rear cabinet 15 simply by aligning 15. Therefore, the process of fixing the wall hanging bracket 20 to the rear cabinet 15 with the mounting screw 200 can be performed relatively easily. On the other hand, in the wall-mounted display device of FIG. 15, the reinforcing frame 40 is not fixed to the display panel 100. After the step of fixing the reinforcing frame 40 superimposed on the position to the rear cabinet 15 is performed, the rear cabinet 15 is aligned with the front cabinet 11, or the wall hanging bracket 20 is fixed to the outer surface of the rear cabinet 15 using the mounting screw 200. It is necessary to perform a process.

  For this reason, in the wall-mounted display device of FIG. 14 and the wall-mounted display device of FIG. 15, in order to share the rear cabinet 15 having the same structure and reduce the cost, the reinforcing frame 40 of FIG. After taking measures that can reduce the number of work steps and the number of parts required for fixing, it is ensured that taking such measures does not become an obstacle to adopting the chassis bracket 30 of FIG. Is required.

  On the other hand, conventionally, in the field of television, by attaching a stand (foot member) to a bracket (corresponding to the chassis bracket) fixed to a PDP (plasma display panel), A configuration for avoiding the addition of weight has been proposed (see, for example, Patent Document 1).

  In the field of liquid crystal television that can be used as a wall-mounted type or a self-supporting type, a liquid crystal panel support plate having wall mounting screw holes at four locations on the main body, and a lower side of the liquid crystal panel support plate When using as a wall-mounted type, use the screw holes on the liquid crystal panel display plate, and when using as a self-standing type, attach a stand to the main body side bracket. Has been proposed (see, for example, Patent Document 2).

In addition, in the field of liquid crystal television, as a measure for easily and firmly attaching a stand member to a housing (corresponding to a cabinet), a plate-shaped metal holding member and a rear cabinet provided on the inner surface side of the rear cabinet. It has been proposed that a rear cabinet is sandwiched between a base member of a stand member disposed on the outer surface side of the stand member and screwed to the rear cabinet (see, for example, Patent Document 3). In Patent Document 3 listed here, as a means for aligning the screw hole of the plate-shaped metal holding member with the position of the screw hole of the rear cabinet, the hook of the metal holding member is attached to the hook portion provided in the rear cabinet. Engaging the engagement holes is disclosed.

  However, Patent Document 1 only teaches measures for reducing the weight applied to the rear cabinet. Patent Document 2 only teaches measures for selecting and using a liquid crystal television as a wall-mounted type or a self-standing type. Further, Patent Document 3 teaches a configuration for facilitating the alignment of the metal holding member and a measure for screwing the rear cabinet between the metal holding member and the base member of the stand member. It is only done.

  Therefore, according to any of the above-mentioned Patent Documents 1 to 3, the reinforcing frame can be attached to the rear cabinet while being applicable to both the chassis bracket shown in FIG. 14 and the reinforcing frame shown in FIG. Even if the necessary measures are taken, nothing is taught about special measures for preventing the measures from becoming an obstacle to the adoption of the chassis bracket.

  The present invention has been made under the above circumstances. In the wall-mounted display device of FIG. 14 and the wall-mounted display device of FIG. 15, screw insertion holes at a plurality of positions of a plate-like wall-mounted metal fitting 20 that is a standard product are provided. Basically, the rear cabinet 15 having screw insertion holes that can be matched can be shared by two types of long and short vertical frames to reduce the cost, and the reinforcing frame 40 of FIG. In taking the chassis bracket 30 of FIG. 14 as a vertically long frame, after taking measures that can reduce the number of work steps and the number of parts necessary for fixing to the rear cabinet 15, the measures are taken. It is an object of the present invention to provide a wall-mounted display device that does not become an obstacle.

  In the wall-mounted display device according to the present invention, a rear cabinet arranged at the back of a display panel is sandwiched between a vertically long frame arranged in an overlapping manner on the inner surface and a plate-like wall-mounted metal fitting arranged on the outer surface side. In this state, the wall-hanging bracket is attached to the rear cabinet by screwing the mounting screws inserted into the screw insertion holes provided at a plurality of positions of the wall-hanging bracket and the rear cabinet into the screw holes of the longitudinal frame. It is supposed to be fixed to. The vertical frame includes a chassis bracket having a length corresponding to the overall height of the rear cabinet and fixed to the display panel, and a reinforcing frame shorter than the chassis bracket. One of the chassis bracket and the reinforcing frame is selectively used.

  According to the wall-mounted display device having this configuration, even when a chassis bracket fixed to the display panel is used as a vertically long frame, or when a reinforcing frame shorter than the chassis bracket is used, With the rear cabinet sandwiched between the vertically long frame and the wall hanging bracket, the wall hanging bracket can be fixed to the rear cabinet using a plurality of mounting screws.

  In the present invention, in particular, the rear cabinet has one screw hole into which the fixing screw inserted into the screw insertion hole provided in the reinforcing frame arranged in an overlapping manner on the inner surface is screwed. And a boss having the inner surface of the rear cabinet in cooperation with the fixing screw screwed into the screwing hole by engaging with the reinforcing frame disposed in an overlapping manner on the inner surface of the boss. A hook is provided in a projecting manner, and the boss and the hook are arranged at positions that do not interfere with the chassis bracket superimposed on the inner surface of the rear cabinet.

  For this reason, when a reinforcing frame shorter than the chassis bracket is used as the vertically long frame, one fixing screw inserted into the screw insertion hole of the reinforcing frame is screwed into the screw hole of the boss on the rear cabinet side, It is possible to fix the reinforcing frame to the inner surface of the rear cabinet simply by engaging the hook on the rear cabinet side with the reinforcing frame. Therefore, it is necessary to use a plurality of mounting screws to fix the chassis bracket to the inner surface of the rear cabinet, whereas the fixing screws required to fix the reinforcing frame to the inner surface of the rear cabinet in an overlapping manner. Only one is required, and the necessary number of fixing screws required to fix the reinforcing frame to the rear cabinet can be reduced to the minimum number of one. This helps to reduce the work process and the number of parts necessary for fixing the reinforcing frame to the rear cabinet.

  Nevertheless, the above-described bosses and hooks used for fixing the reinforcing frame to the rear cabinet use the chassis bracket by being disposed at a position that does not interfere with the chassis bracket superimposed on the inner surface of the rear cabinet. In this case, the chassis bracket can be fixed to the rear cabinet without difficulty. Therefore, the boss and hook described above do not become an obstacle when the chassis bracket is fixed to the rear cabinet.

  In the present invention, the hook includes a first hook piece that engages with a laterally extending piece provided on the reinforcing frame, and a second hook piece that engages with a mouth edge of an opening formed in the reinforcing frame. The reinforcement frame is separated and overlapped with the inner surface of the rear cabinet so that the laterally extending piece is engaged with the first hook piece and the second hook piece is inserted into the opening. It is desirable that the screw insertion hole of the reinforcing frame is aligned with the screw hole of the boss through an operation of sliding the frame to engage the second hook piece with the opening edge of the opening. . According to this, when the reinforcing frame is used, the screw insertion hole of the reinforcing frame can be screwed into the screw of the boss on the rear cabinet side only by performing the operation of engaging the second hook piece with the opening edge of the opening of the reinforcing frame. It can be easily and reliably aligned with the hole. Therefore, the reinforcing frame can be easily and accurately fixed to the rear cabinet quickly.

  In the present invention, the chassis bracket has a narrow portion where the first hook piece is positioned on a side portion of the chassis bracket superimposed on the inner surface of the rear cabinet, and the chassis bracket is disposed on the inner surface of the rear cabinet. It has an escape structure comprising an opening for loosely fitting the second hook piece when overlapped and an opening for loosely fitting the boss. Here, the narrow portion where the first hook piece is positioned on the side portion of the chassis bracket can be formed by narrowing the chassis bracket at its entire length, or only a portion of the chassis bracket can be narrowed. It can also be formed.

  In the present invention, it is desirable that frame attachment sections to which the reinforcing frame as the vertically long frame and the chassis bracket are selectively attached are formed at two locations in the width direction of the inner surface of the rear cabinet. With this configuration, the wall mounting bracket is screwed in two places on the left and right sides, although it is not necessary to use a reinforcing frame and chassis bracket with a width suitable for the plate-shaped wall mounting bracket. improves.

  As described above, according to the present invention, even when a long chassis bracket fixed to a display panel is used as a longitudinal frame for reinforcement that prevents deformation of the rear cabinet, it is shorter than the chassis bracket. Even when a reinforced frame is used, it is possible not only to reduce the cost by sharing the same rear cabinet, but also when using the reinforced frame as a vertically long frame, There is an effect that the number of work steps and the number of parts necessary for fixing to the rear cabinet are reduced.

  Therefore, it is possible to provide a wall-mounted display device that can selectively use the chassis bracket and the reinforcing frame at low cost.

As described above with reference to FIG. 14, the chassis bracket 30 is fixed to the display panel 100 whose back is covered by the rear cabinet 15. For fixing the chassis bracket 30 to the display panel 100, an upper screw fixing piece 31 and a lower screw fixing piece 32 of the chassis bracket 30 are used. Accordingly, the chassis bracket 30 itself serves as a skeleton structure of the display panel 100.

  The chassis bracket 30 is provided with screw holes 33 and 34 at two upper and lower positions, and a rectangular vertically long opening 35 and a rectangular opening are provided at positions between the upper and lower screw holes 33 and 34. Department 36 is established. Moreover, the mutual space | interval of the upper and lower screw holes 33 and 34 of the chassis bracket 30 is the mutual space | interval of the upper and lower screw insertion holes 21 and 21 of the plate-shaped wall-mounting metal fitting 20 which is a standard product already described with reference to FIG. The intervals are the same.

  As described above, the chassis bracket 30 is fixed to the display panel 100 in advance. Therefore, if the display panel 100 is attached to the front cabinet 11 as described with reference to FIG. 14, the chassis bracket can be placed at a predetermined position on the inner surface of the rear cabinet 15 simply by aligning the rear cabinet 15 with the front cabinet 11. 30 overlap. Therefore, as can be seen from FIG. 8, the upper and lower screw insertion holes 21, 21, 16, 17 provided on the plate-like wall-hanging bracket 20 and the rear cabinet 15 that are superimposed on the outer surface (rear surface) of the rear cabinet 15, respectively. The wall mounting bracket 20 is fixed to the rear cabinet 15 as shown in FIG. 2 simply by screwing and tightening the mounting screws 200 inserted into the upper and lower screw holes 33 and 34 of the chassis bracket 30.

  In this structure, that is, the rear cabinet 15 includes a chassis bracket 30 having screw holes 33 and 34 at two upper and lower portions, and a plate-like wall-hanging metal fitting 20 as a standard product having screw insertion holes 21 at four corners. The total number of mounting screws 200 necessary for adopting a structure in which the wall hanging bracket 20 is fixed to the rear cabinet 15 using the mounting screws 200 while being sandwiched between them is four, two of which are on the left side. The remaining two screws are screwed into the screw holes 33 and 34 of the right chassis bracket 30.

  When the wall hanging bracket 20 is fixed to the rear cabinet 15 in the structure shown in FIG. 2, the chassis bracket 30 that is superimposed on the inner surface of the rear cabinet 15 and is screwed with the mounting screw 200 prevents the rear cabinet 15 from being deformed. Useful. Further, since the chassis bracket 15 has a length corresponding to the overall height of the rear cabinet 15 as shown in FIG. 2, the overall height of the rear cabinet 15 is reinforced by the chassis bracket 15. . From this, it can be said that it is desirable for the wall-mounted display device having a large display panel 100 (see FIG. 14) to have the wall-mounted metal fitting 20 attached thereto with the structure shown in FIG.

  As shown in FIG. 7, the reinforcing frame 40 is made of sheet metal and has a U-shaped horizontal cross section. The reinforcing frame 40 is provided with bosses 41 and 42 having screw holes (not shown in the drawing) at two upper and lower positions, and a rectangular position is formed between the positions where the upper and lower bosses 41 and 42 are formed. A vertically long opening 43 and a rectangular opening 44 are opened, and the lower opening 44 corresponds to the trace of the cut-and-raised piece 45 of the both-sided structure straddling the opening 44 up and down. Yes. A screw insertion hole 46 is formed in the cut and raised piece 45. The mutual spacing between the screw holes provided in each of the upper and lower bosses 41 and 42 of the reinforcing frame 40 is such that the upper and lower screws of the plate-like wall hanging bracket 20 which is the standard product described with reference to FIG. The interval is the same as the interval between the insertion holes 21 and 21.

Further, a laterally extending piece 47 is provided at one location on the upper end of the reinforcing frame 40.

  The reinforcing frame 40 shown in FIG. 7 is not fixed to the display panel 100 as described above with reference to FIG. Moreover, the wall-hanging metal fitting 20 is fixed to the rear cabinet 15 coupled to the front cabinet 11 shown in FIG. Therefore, in order to fix the wall hanging bracket 20 to the outer surface of the rear cabinet 15 using the reinforcing frame 40, it is necessary to fix the reinforcing frame 40 to the rear cabinet 15 prior to screwing the wall hanging bracket 20. There is.

  Therefore, in this embodiment, by taking the measures described below, the reinforcement frame 40 can be easily and accurately fixed to the rear cabinet 15 quickly.

  That is, as shown in FIG. 1, in each of the two left and right frame mounting sections S, S on the inner surface of the rear cabinet 15, one screw hole (appears in the figure) into which a fixing screw (not shown in FIG. 1) is screwed. A boss 51 having a not-shown) and a hook 60 are projected. Then, as can be inferred from FIG. 3 or FIG. 5, among the boss 51 and the hook 60 described above, the screw-in hole of the boss 51 has a reinforcing frame 40 disposed in an overlapping manner on the inner surface of the rear cabinet 15. The fixed screw (not shown in FIG. 3) inserted into the screw insertion hole 46 of the cut and raised piece 45 is screwed. The hook 60 is divided into a first hook piece 61 and a second hook piece 62, and the first hook piece 61 is a laterally extending piece 47 of the reinforcing frame 40 arranged in an overlapping manner on the inner surface of the rear cabinet 15. The second hook piece 62 is adapted to engage with the mouth edge 43a of the opening 43 of the reinforcing frame 40 disposed in an overlapping manner on the inner surface of the rear cabinet 15. In this embodiment, a support portion 65 is provided corresponding to the first hook piece 61, and the reinforcement frame 40 is backed up by the support portion 65, so that the side face is engaged with the first hook piece 61. The overhanging piece 47 is prevented from coming out of the first hook piece 61. In addition, the support portion 65 that backs up the reinforcement frame 40 arranged on the left side in FIG. 3 utilizes the step formed on the inner surface of the rear cabinet 15, whereas the reinforcement portion arranged on the right side. A rib projecting from the inner surface of the rear cabinet 15 is utilized for the support portion 65 that backs up the frame 40.

  The operation of fixing the reinforcing frame 40 to the inner surface of the rear cabinet 15 is performed, for example, through the following steps. That is, as shown in FIG. 9, on the inner surface side of the rear cabinet 15, the opening 43 of the reinforcing frame 40 is aligned with the second hook piece 62 on the rear cabinet 15 side, and the opening 44 of the reinforcing frame 40 is aligned with the rear cabinet. Align with the boss 51 on the 15 side. Thereafter, as shown by an arrow C in FIG. 12, the laterally extending piece 47 of the reinforcing frame 40 is inserted into the first hook piece 61 on the rear cabinet 15 side, and the first hook piece 61 and the support portion 65 (see FIG. 3 or FIG. 5). The reinforcing frame 40 is placed between the reinforcing frame 40 and the inner surface of the rear cabinet 15 as shown by an arrow A in FIG. 10, and the second hook piece 62 is fitted into the opening 43 of the reinforcing frame 40. Then, the boss 51 is fitted into the opening 44 of the reinforcing frame 40. Subsequently, the reinforcing frame 40 is slid on the inner surface of the rear cabinet 15 as shown by an arrow B in FIG. 11 while the laterally extending piece 47 is engaged with the first hook piece 61, thereby causing the second hook piece 62 to move. The mouth edge 43a of the opening 43 of the reinforcing frame 40 is engaged. Thus, when the mouth portion 43a of the opening 43 of the reinforcing frame 40 is engaged with the second hook piece 62, the first hook piece 61 is kept engaged with the laterally extending piece 47 as shown in FIG. As shown in FIG. 11, the screw holes 48 and 49 of the bosses 41 and 42 of the reinforcing frame 40 coincide with the screw insertion holes 16 and 17 of the rear cabinet 15, and the screw insertion holes 46 of the cut and raised pieces 45 of the reinforcing frame 40. Corresponds to the screw hole 52 of the boss 51 on the rear cabinet 15 side. Therefore, when the fixed screw 50 is inserted into the screw insertion hole 46 and screwed into the screw hole 52 of the boss 51 and tightened, the reinforcing frame 40 is fixed to the inner surface of the rear cabinet 15.

  In the above-described operation for fixing the reinforcing frame 40 described with reference to FIGS. 9 and 10 to the inner surface of the rear cabinet 15, only one fixing screw 50 is required for fixing. This is because the first hook piece 61 as the hook 60 engages the laterally extending piece 47 of the reinforcing frame 40 and presses the reinforcing frame 40 against the inner surface of the rear cabinet 15, and the second hook piece 62 as the hook 60. Is engaged with the mouth edge 43 a of the reinforcing frame 40 and presses the reinforcing frame 40 against the inner surface of the rear cabinet 15. Therefore, according to this structure, since the first hook piece 61 and the second hook piece 62 are engaged with the laterally extending piece 47 and the mouth edge portion 43a of the reinforcing frame 40, one fixing screw 50 is used. As a result, the reinforcing frame 40 can be fixed to the inner surface of the rear cabinet 15 easily, accurately and quickly.

  When the reinforcing frame 40 is fixed to the inner surface of the rear cabinet 15 with the structure described in FIGS. 11 and 13, even after the rear cabinet 15 is joined to the front cabinet 11 as shown in FIG. 15, The plate-like wall hanging bracket 20 can be fixed to the rear cabinet 15. That is, as can be seen from FIG. 11, the upper and lower screw insertion holes 21, 21, 16, and 17 provided in the plate-like wall-hanging bracket 20 and the rear cabinet 15 superimposed on the outer surface (rear surface) of the rear cabinet 15, respectively. The mounting screws 200 inserted into the upper and lower bosses 41 and 42 of the reinforcing frame 40 are simply screwed into the respective screw holes 48 and 49 and tightened, so that the wall-hanging bracket 20 does not float on the rear cabinet 15 as shown in FIG. It is fixed.

  By the way, in this embodiment, in the rear cabinet 15 in which the long chassis bracket 30 as the vertically long frame 60 and the short reinforcing frame 40 as the vertically long frame 60 are selectively used selectively, they are not fixed to the display panel 100. As a measure for improving workability when the reinforcing frame 40 is fixed to the rear cabinet 15 or reducing the number of the fixing screws 50 to only one, hooks 60 and bosses 51 are projected on the inner surface of the rear cabinet 15. It is. A support portion 65 is also provided on the inner surface of the rear cabinet 15. Therefore, it is required that these hooks 60, bosses 51, and support portions 65 do not become an obstacle when the chassis bracket 30 is superimposed on the inner surface of the rear cabinet 15.

  Therefore, in this embodiment, the boss 51, the hook 60, and the support portion 65 are arranged at a position where they do not interfere with the chassis bracket 30 superimposed on the inner surface of the rear cabinet 15. That is, as shown in FIG. 4, the boss 51 is loosely fitted into the opening 36 of the chassis bracket 30 superimposed on the inner surface of the rear cabinet 15, and the second hook piece 62 forming the hook 60 is It is configured to loosely fit into the opening 35 of the chassis bracket 30 superimposed on the inner surface of the rear cabinet 15.
