Description

  The present invention relates to a television mounting panel, and more particularly to the structure of a television mounting panel used for mounting a thin television such as a liquid crystal television or a plasma television on a wall.

  Conventionally, when viewing a flat-screen TV on a wall, the TV is not directly mounted on a housing frame (for example, a partition wall), but is mounted on a dedicated TV mounting panel. Various attempts have been made to prevent leakage to the next room behind the wall.

  Further, as a method of suppressing the propagation of solid vibration to the rear surface of the television mounting panel, it is conceivable to increase the weight of the television mounting panel itself or to increase the depth dimension of the television mounting panel. However, if the weight of the television mounting panel itself is increased, it becomes difficult to carry in and install when actually installing in a house. Also, if the depth dimension of the TV mounting panel is increased, the projecting dimension toward the front of the wall will increase even though the thin TV is intended to be installed. Disappear.

  Therefore, conventionally, as shown in FIG. 8, a part of the front surface of the front plate 54 attached to the front surface of the frame 53 having a height from the floor 51 to the ceiling 52 is attached to the television mounting portion 55 for attaching the thin television 1. At the same time, a reinforcing plate 56 is provided on the back side of the television mounting portion 55 of the front plate 54 to constitute a television fixing auxiliary wall 57. The TV fixing auxiliary wall 57 is erected so as to extend over the floor 51 and the ceiling 52, and the TV fixing auxiliary wall 57 is fixed only to the floor 51 and the ceiling 52 with respect to the house. Furthermore, a space 59 is formed between the TV fixing auxiliary wall 57 and the wall 58 by laying the middle horizontal frame 60 at a plurality of vertical positions between the back surface of the front plate 54 of the frame 53 and the wall 58. The structure is known (see, for example, Patent Document 1).

  As another conventional example, when an image display device such as a television or a monitor is attached along the wall surface, a flat box-shaped space unit having a hollow inside is assembled along the wall. A structure is known in which an image display device is attached to the front plate of the space unit (see, for example, Patent Document 2).

JP 2007-224619 A JP 2010-62796 A

  However, in the conventional example shown in Patent Document 1, a space 59 for suppressing vibration propagation is formed between the reinforcing plate 56 and the wall 58 of the TV fixing auxiliary wall 57. When viewing 1, there is a problem that solid vibration using the television 1 as a vibration source is transmitted to the wall 58 through a plurality of upper and lower middle horizontal frames 60 provided to secure the space 59.

  Further, in the conventional example of Patent Document 2, there is a problem that when watching a television, solid vibration using the television as a vibration source is transmitted to the wall surface through the outer portion of the space unit in which the inside is hollow. For this reason, in any conventional example, the sound insulation performance on the rear surface of the television is not sufficient.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a television mounting panel capable of suppressing propagation of solid vibration from a television installation surface side to a wall surface side using a television as a vibration source. It is to provide.

  In order to solve the above-mentioned problem, a first invention is a television mounting panel that is interposed between a partition wall of a building and a television and is used to hang a television on the partition wall, and fixes the television TV fixing plate, front frame attached to the TV fixing plate, wall fixing plate fixed to the partition wall, rear frame attached to the wall fixing plate, front frame and rear side And a connecting member that connects a part of the opposed portions of the front frame and the rear frame in a state where a gap is formed between the frame and a predetermined interval. And

  The second invention is the active noise control according to the first invention, wherein the back side of the front frame is closed with a partition wall and a control sound for muting the sound leaking from the back of the television is output to the front side of the partition wall. A speaker is attached.

  According to a third invention, in the first or second invention, a vibration damping material is disposed between the front frame and the rear frame.

  According to a fourth invention, in any one of the first to third inventions, the front frame body and the rear frame body are each formed by assembling a plurality of vertical frames and a plurality of horizontal frames in a lattice shape. And a part of a portion where the vertical frame and the horizontal frame intersect in the front frame, and a portion where the vertical frame and the horizontal frame in the rear frame opposite to the part of the portion intersect. A part is connected by the connecting member.

  5th invention is equipped with the curvature prevention member for joining a part of site | part of the said front side frame body and the said back side frame body which are not connected by the said connection member in a 4th invention at predetermined intervals. It is characterized by that.

  The present invention can suppress the propagation of solid vibration using a television as a vibration source from the television installation surface side to the wall surface side of the television mounting panel.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a usage example of the television mounting panel 3 of the present embodiment, and FIG. 2 is an exploded perspective view of the television mounting panel 3.

  The TV mounting panel 3 includes both a front frame 6 to which the TV fixing plate 4 is mounted, a rear frame 8 to be mounted on the wall fixing plate 7, and a gap 9 formed between both the frames 6 and 8. It is comprised with the connection member 5 for mutually connecting a part of site | part which the frame bodies 6 and 8 oppose.

  As shown in FIG. 2, the front frame 6 is configured by assembling a plurality of vertical frames 11 and a plurality of horizontal frames 12 in a lattice shape. The rear frame body 8 is a separate body from the front frame body 6 and is configured in a lattice shape having the same structure and the same size as the front frame body 6.

  A flat TV fixing plate 4 whose front surface is a TV installation surface is attached to the front surface of the front frame 6 by a fixing means (not shown). A flat plate-like wall fixing plate 7 whose rear surface is a wall mounting surface is attached to the rear surface of the rear frame 8 by an adhering means (not shown).

  In the connecting member 5, a part of the portion where the vertical frame 11 and the horizontal frame 12 of the front frame 6 intersect with each other, and the vertical frame 11 and the horizontal frame 12 of the rear frame 8 facing this part of the connecting member 5 intersect. Some parts are connected to each other. In FIG. 3, the part of both frame bodies 6, 8 connected by the connecting member 5 is referred to as a first intersecting portion 10a, and the other part of both frame bodies 6, 8 not connected by the connecting member 5 is the second intersection. This is referred to as part 10b. In addition, the 2nd cross | intersection part 10b is joined using the curvature prevention member 20 (FIG. 5) mentioned later.

  The connecting member 5 that connects the first intersecting portion 10a will be described.

  As shown in FIG. 4, the connecting member 5 of this example has a joining spacer 14 sandwiched between a pair of joining sleeves 13, 13 and fastens the joining sleeves 13, 13 with bolts 15 and nuts 16. It is.

  A through-hole 17 that penetrates in the front-rear direction is formed in each of the first intersecting portions 10a of both frame bodies 6 and 8. At the front end of the through hole 17 of the front frame body 6, a recess 18 a that is open forward to accommodate the head of the bolt 15 is formed, and at the rear end of the through hole 17 of the rear frame body 8 is a nut. A recess 18b that is open to the rear where 16 can be stored is formed.

  A tubular portion 13 a of one joining sleeve 13 is embedded in the through hole 17 of the front frame 6, and a flange portion 13 b provided at the rear end of the tubular portion 13 a is in close contact with the back surface of the front frame 6. It is exposed in the state.

  A tubular portion 13 a of the other joining sleeve 13 is embedded in the through hole 17 of the rear frame 8, and a flange portion 13 b provided at the front end of the tubular portion 13 a is formed on the front surface of the rear frame 8. Exposed in close contact.

  A cylindrical joining spacer 14 is interposed between the flange portions 13b, 13b of the joining sleeves 13, 13. The joining spacer 14 is arranged coaxially with the joining sleeves 13 and 13, and both ends in the axial direction of the joining spacer 14 are flange portions of both joining sleeves 13 as shown in FIG. The contact surfaces 14a are in contact with the outer surfaces of 13b. Further, in order to make it difficult for vibration to propagate, each contact surface 14 a is formed in a tapered shape with a sharp tip, and the contact surface 14 a is a point (or a circle) with respect to the flange portion 13 b of the joining sleeve 13. ) To come into contact.

  When connecting the first intersecting portions 10a of the two frame bodies 6 and 8, the bolt 15 is passed from the recess 18a side of the front frame body 6 into one of the joining sleeves 13 in the through hole 17 and further joined to the joining spacer. 14 passes through the inside of the other joining sleeve 13 and protrudes into the recess 18b of the rear frame 8, and the nut 16 is fastened to the tip of the bolt 15 in the recess 18b. By fastening the bolts and nuts, the frame bodies 6 and 8 are connected to each other at the first intersecting portion 10a. At the same time, the gap portion 9 is spaced between the frame bodies 6 and 8 by a joining spacer 14 with a predetermined interval. It becomes a secured state.

  Thus, when viewing the television 1, solid vibration using the television 1 as a vibration source or sound of the television 1 is once radiated indoors, and reaches the surface of the television mounting panel 3 due to diffraction or reflection. Is absorbed in the gap 9 of the television mounting panel 3. Furthermore, as shown in FIGS. 1A and 1B, the two frame bodies 6 and 8 that are adjacent to each other with the gap portion 9 secured the gap portion 9 by only a part of the first intersection portions 10a that intersect each other. In this state, the connecting members 5 are connected to each other, so that the only member that propagates vibration between the frame bodies 6 and 8 is the connecting member 5.

  Here, in FIG. 4, regarding the vibration propagation from one joining sleeve 13 to the other joining sleeve 13 through the joining spacer 14 in the connecting member 5, both ends of the joining spacer 14 are used in this example. Each of the contact surfaces 14a provided on the taper has a tapered shape with a sharp tip. The contact surface 14a comes into contact with the flange portion 13b of the joining sleeve 13 at a point (or a circle), so that the contact area between the joining spacer 14 and the joining sleeve 13 becomes as small as possible. The vibration propagation by the spacer 14 is suppressed as much as possible.

  Therefore, the vibration propagation from the front frame 6 to the rear frame 8 is only the elongated bolt 15. As a result, vibration propagation from the TV fixing plate 4 (TV installation surface side) to the wall fixing plate 7 (wall surface side) through the connecting member 5 is sufficiently suppressed, and the sound insulation performance on the TV rear side is greatly improved. There is.

  By the way, when fastening the front side frame body 6 and the rear side frame body 8 with the bolt 15 and the nut 16, in order to reduce vibration propagation more, it is possible to reduce the number of bolt and nut fastening parts, for example. However, if it is reduced too much, there arises a disadvantage that the joint strength between the frames 6 and 8 is lowered. Moreover, in the site | part which is not fastened with the volt | bolt 15 of both the frame bodies 6 and 8, both the frame bodies 6 and 8 are in the state which floated mutually, and if a curvature generate | occur | produces in any one of the frame bodies 6 and 8, temporarily, There is also an inconvenience that the frames 6 and 8 come into contact with each other and propagate vibrations.

  Therefore, in this example, at the second intersecting portion 10b of the two frames 6 and 8 that are not connected by the connecting member 5 shown in FIG. 3, the warpage prevention member 20 is used to prevent the warpage from occurring and the bonding strength. We are trying to improve.

  As shown in FIG. 5, the warpage preventing member 20 of the present example includes a front connection tool 21 having a flange portion 21 b on the front end side and a convex connection surface 21 a protruding further toward the front end than the flange portion 21 b, and a front end. The rear connection tool 22 has a flange portion 22b on the side and a concave connection surface 22a that protrudes further toward the tip than the flange portion 22b. The base portions are embedded in the frame bodies 6 and 8 rather than the flange portions 21b and 22b of the connection tools 21 and 22, respectively, and the connection surfaces 21a and 22a at the leading ends are butted together. Here, the connection surface 21a of the front connection tool 21 has a sharp convex shape, while the connection surface 22a of the rear connection tool 22 has a round concave shape. And since both the connection surfaces 21a and 22a are in point contact, vibration propagation is suppressed and at the same time point contact is made with a certain degree of freedom. Even when fastened, the connection surfaces 21a and 22a of both the connectors 21 and 22 are not deformed by the tightening load. Moreover, even if the area of the concave connection surface 22a of the rear connection tool 22 is small, the convex connection surface 21a of the front connection tool 21 is reliably received, and the contact position does not shift.

  In this way, the second intersecting portion 10b (FIG. 3) of both the frame bodies 6 and 8 is abutted in contact with the warpage preventing member 20 (FIG. 5), so that the number of the connecting members 5 is not increased. The joining strength of the frames 6 and 8 can be secured. At the same time, the vibration propagation of the warp preventing member 20 itself is extremely small. Therefore, since both the frame bodies 6 and 8 can be fastened more reliably and strongly using the connecting member 5 and the warp preventing member 20, the television mounting panel 3 can sufficiently withstand the load of the television 1 and at the same time. It is also possible to demonstrate an excellent effect in sound insulation on the back of the TV.

  FIG. 6 shows still another embodiment, in which the back surface of the front frame 6 of the television mounting panel 3 is closed with a back plate 25 serving as a partition wall. An active noise control speaker 30 (hereinafter referred to as a control speaker 30) that outputs a control sound for muting the sound coming out from the back of the television 1 is attached to the front side of the back plate 25. In addition, the structure which secures the space | gap part 9 between both frame bodies 6 and 8 and connects with the connection member 5 is the same as that of the said embodiment. In this example, so-called active noise control is performed in which the control sound output from the control speaker 30 is phase-interfered with the sound of the television 1 to cancel the sound from the television 1. This active noise control technique is known, for example, in Japanese Patent Laid-Open No. 2008-32767, and detailed description thereof is omitted. The hatched portion R in FIG. 6B indicates an area where a plurality of control speakers 30 are arranged.

  Thus, the television mounting panel 3 of this example has a control speaker 30 built in the front frame 6 and drives the control speaker 30 when viewing the television 1 to generate a sound output that cancels the sound of the television 1. By doing so, it is possible to obtain a sound muting effect of the sound leaking behind the television 1. In addition, the vibration of the control speaker 30 itself or the reverse phase sound generated by the acoustic vibration radiated from the back surface of the control speaker 30 stops solidly propagating from the back plate 25 to the front frame body 6, The vibration propagation to the rear frame 8 connected by the connecting member 5 is sufficiently suppressed. As a result, the sound insulation performance on the back of the television 1 can be further improved by outputting sound from the television 1 and driving (sound output) the control speaker 30 inside the television mounting panel 3.

  FIG. 7 shows still another embodiment and shows an example in which a damping material 40 is interposed between both frame bodies 6 and 8 of the television mounting panel 3. In addition, the structure which secures the space | gap part 9 between both frame bodies 6 and 8 and connects with the connection member 5 is the same as that of the said embodiment. In this example, as the damping material 40, for example, a sheet-like material having a vibration absorbing function such as rubber, plastic, and asphalt is used. This sheet-like material is the same size as the two frames 6 and 8. The vibration-damping material 40 is sandwiched between the two frame bodies 6 and 8, and the both frame bodies 6 and 8 are connected to each other by the connecting member 5 shown in FIG. Since unnecessary vibrations can be absorbed by the damping material 40, vibration propagation to the wall fixing plate 7 (wall surface side) can be further suppressed. Further, by sandwiching the vibration damping material 40 between the frame bodies 6 and 8, there is also an advantage that it is possible to prevent the entry of dust, dust and the like into the gap portion 9 (FIG. 1).
