Description

  The present invention relates to a heavy object fixing wall for fixing a heavy object such as a large screen television or a picture.

  In recent years, large-screen televisions such as liquid crystal and plasma have become low-priced, and the sales volume of these large-screen televisions is increasing rapidly. Large-screen TVs such as liquid crystal and plasma are thinner than conventional CRT TVs, so you can not only support the large-screen TV from the floor with a TV stand like before, but also make the room clean by hanging it on the wall It is also proposed that

  However, because of the large weight of a large-screen TV, although it is thin, it is not something that can be hung anywhere on the existing wall surface. However, because there are many cases where there are no pillars at the desired position, it is not necessary to directly fix the large screen TV to the existing wall surface. And attach a large-screen TV (hereinafter referred to as “heavy object” as a concept that encompasses all objects used on a large-screen TV, paintings or other walls) to the heavy-weight fixing wall. Has been proposed (for example, Patent Document 1).

  The heavy object fixing wall 1 of Patent Document 1 will be briefly described with reference to FIG. 17. The heavy object fixing wall 1 is arranged on the surface side of the existing wall surface A, and the upper end is screwed to the existing ceiling surface B. The frame 3 fixed at 2 and having the lower end fixed to the existing floor C, a plurality of horizontal beams 4 installed on the frame 3 in the horizontal direction, and a heavy object A heavy load attachment plate 5 that receives most of the load of X, a plurality of decorative plates 6 that are attached to the surface of the frame 3 so as to cover the heavy load attachment plate 5, and a front end face of the horizontal rail 4 The attached base portion 7a, the projecting piece 7b projecting from the base portion 7a, and the upper engaging piece projecting in the vertical direction from the front end portion of the projecting piece 7b and extending in the left-right direction with substantially the same length as the lateral width of the decorative plate 6 7c and the lower engaging piece 7d, and the fixture 7 integrally formed. And the engagement groove | channel 8 with which the upper engagement piece 7c or the lower engagement piece 7d of the fixture 7 is engaged is provided in the upper end surface and lower end surface of the decorative board 6, It is attached to the surface of the frame 3 via the fixture 7.

According to the heavy object fixing wall 1, the heavy object X fixed to the heavy object attachment plate 5 via the decorative plate 6 by the metal fitting is supported by the existing ceiling surface B and floor surface C via the frame 3. Therefore, the heavy object X can be fixed at a desired position regardless of the position of the existing pillar D.

  However, according to the weight fixing wall 1 of the above-mentioned Patent Document 1, there are the following problems. That is, the frame 3 of the heavy-weight fixing wall 1 occupies the existing ceiling surface B to the floor surface C from the mounting method on the front side of the existing wall surface A. When a hanging door is to be attached to the upper part of the screen TV, it must be attached in front of the heavy object fixing wall 1 and the hanging door comes out to the front by the thickness of the heavy object fixing wall 1. There was a problem of space loss and poor appearance.

  Further, when attaching the plurality of decorative plates 6 to the frame 3, after fitting the upper engaging pieces 7 c of the fixture 7 in the engaging grooves 8 provided on the lower end surface of the decorative plate 6, The lower engagement piece 7d of another fixture 7 is fitted into the engagement groove 8 provided on the upper end surface of the decorative plate 6 while the plate 6 is kept along the surface of the frame 3, and in this state The other fixture 7 must be fixed to the surface of the horizontal rail 4 with a nail 9a or the like, and there is a problem that the workability of the decorative board 6 is poor. More specifically, since the upper end surface of the decorative plate 6 attached to the uppermost stage cannot be fixed by the fixture 7, the upper end portion of the uppermost decorative plate 6 must be fixed to the frame 3 with a nail 9b or the like. In other words, the heads of the nails 9b and the like are exposed and there is a problem that the appearance is poor.

  In addition, when the engagement groove 8 is provided on the end surface of the decorative plate 6, the thickness of the decorative plate 6 around the engagement groove 8 is inevitably thin, and the strength of the end surface is insufficient, so that it is being conveyed or assembled. There was a problem of damage. This is particularly remarkable when an inorganic board (calcium silicate board, volcanic glassy multilayer board, or the like) is used as the decorative board 6. Further, since the engagement groove 8 is provided, there is a problem that a thin plate material cannot be used for the decorative plate 6. Moreover, according to the thickness of the decorative board 6, the fixture 7 from which the length of the protrusion 7b differs must be prepared, and there also existed a problem that the kind of fixture 7 increased.

  The present invention has been developed in view of such problems of the prior art. Therefore, a main object of the present invention is to provide a heavy object fixing wall capable of solving the above-described problems.

The invention described in claim 1 is described as follows: “A pair of left and right vertical frames 24, a pair of upper and lower horizontal frames 26, and a horizontal rail 28 that is installed between the pair of vertical frames 24 and fixed to an existing pillar D. A frame 12 that is constructed between a plurality of vertical rails 30 that are installed between the pair of horizontal frames 26 and fixed to the horizontal rails 28, and whose rear surface is attached to an existing wall surface A;
A heavy load attachment plate 14 which is installed between the plurality of vertical rails 30 to which the heavy load X is fixed;
An upper decorative plate 16 attached to the uppermost portion of the surface of the frame 12 on the front side of the heavy load attaching plate 14;

The lower decorative plate mounting tool 22 for attaching the lower decorative plate 18 is:
The attached member 44 projecting from one of the pair of vertical frames 24 toward the other vertical frame 24, and attached to the back surface of the lower decorative plate 18, and downward on the back surface side of the lower decorative plate 18 It is composed of an attachment member 42 having an attachment recess 48 that is opened and into which the attached member 44 is fitted,
One of the opposing surfaces of the upper decorative plate 16 and the lower decorative plate 18 is provided with a convex member 70 extending toward the other surface, corresponding to the convex member 70 on the other surface. In the position, there is provided a fitting hole 72 into which the convex member 70 is fitted.

  According to the present invention, since the frame body 12 is supported by the existing pillar D via the horizontal rail 28, the heavy object fixing wall 10 is held in a state of being separated from the existing ceiling surface B and floor surface C. Can do.

  Further, the upper decorative plate 16 and the lower decorative plate 18 (the number of decorative plates may be three or more. In this case, the third and subsequent decorative plates are sequentially attached to the lower side of the lower decorative plate 18). When attaching the frame 12 to the frame 12, first, the lower decorative plate 18 is attached to the frame 12 via the lower decorative plate attachment 22, and then the upper decorative plate attachment 20 and the upper decorative plate 16 are attached to the frame 12. Attach to. More specifically, the lower decorative plate 18 is lowered from the position slightly higher than the planned mounting position to the planned mounting position along the surface of the frame body 12. At this time, the mounting recesses 48 of the mounting member 42 opened downward receive the mounted members 44 projecting from the respective vertical frames 24 of the frame body 12 toward the other vertical frame 24 from below. The attachment member 44 engages with the attachment member 42, and as a result, the lower decorative plate 18 is fixed to the surface of the frame body 12.

  Next, the upper decorative plate 16 is slightly inclined, and the attached member 44 is fitted into the attachment recess 48 of the attaching member 42 that opens upward, and the lower end portion of the upper decorative plate 16 is centered on the attached member 44.

  According to the present invention, it is possible to fix a heavy object such as a large-screen TV at a desired position regardless of the position of an existing column. For example, even when it is desired to attach a suspension door to the upper part of a large-screen television, no space loss occurs, and it can be attached with a good appearance. Further, even when an AV rack or the like that accommodates a DVD recorder or the like is arranged on the floor surface, similarly, no space loss occurs and the arrangement can be arranged with good appearance.

  Further, as described above, the upper decorative plate and the lower decorative plate can be attached to the frame body without using a tool such as a hammer or a screwdriver, so that the workability of the decorative plates (upper decorative plate and lower decorative plate) is improved. It can be significantly improved. At the same time, since the head of a nail or a bolt is not exposed on the surface of the decorative board, the surface of the decorative board can be finished with a good appearance.

  Furthermore, since it is not necessary to provide engagement grooves on the end faces of the upper decorative plate and the lower decorative plate, the thickness of the decorative plate is reduced, the strength of the end surface is insufficient, and the decorative plate is not damaged. Can be used. Further, since the decorative plates can be directly joined to each other, it is not necessary to prepare a plurality of types of metal fittings according to the thickness of the decorative plate.

After the frame body 12 is formed, each attached member 44 of the upper decorative plate attachment 20 and the lower decorative plate attachment 22 is attached to the vertical frame 24 with screws 62. Of course, the frame body 12 may be formed using the vertical frame 24 to which the attached member 44 is attached in advance.

  Next, as shown in FIG. 11, with the frame 12 held at a desired position on the existing wall surface A, the upper horizontal frame 26 and each cross rail 28 are connected to the existing column D (a large column or a column by a screw 64). It may be fixed). At that time, it goes without saying that the vertical and horizontal of the frame 12 should be confirmed using the level E. Also, care should be taken so that the frame 12 does not interfere with the existing power outlet or the TV antenna terminal F installed on the existing wall surface A so that wiring can be easily performed. In the present embodiment, three horizontal bars 28 are fixed to three existing pillars D using nine screws 64, but the number of screws 64 and horizontal bars 28 is not limited to this, and the weight The optimum number is selected according to the weight of the object X and the number or position of the columns.

  After the frame body 12 is fixed to the existing wall surface A, the heavy load attachment plate 14 and the wiring decorative plate 37 are fixed to the vertical rail 30 of the frame body 12 with screws 34 as shown in FIG.

  And the upper decorative board 16 and the lower decorative board 18 which attached the attachment member 42 beforehand to the back surface are attached in the following procedures. That is, as shown in FIG. 13, the lower decorative plate 18 is lowered from a position slightly higher than the planned attachment position to the planned installation position along the surface of the frame body 12. At this time, the mounting recess 48 formed on the back surface of the lower decorative plate 18 receives the locked portion 56 of the mounted member 44 attached to the vertical frame 24 of the frame body 12 from below, thereby lowering the lower decorative plate. 18 is fixed to the surface of the frame 12.

  After fixing the lower decorative plate 18 to the surface of the frame body 12, as shown in FIG. 14, the upper decorative plate 16 is slightly inclined, and the mounted member 44 is placed in the mounting recess 48 of the mounting member 42 that opens upward. The upper decorative plate 16 is rotated along the surface of the frame body 12 by rotating the lower end portion of the upper decorative plate 16 toward the frame body 12 with the attached member 44 as the central axis. Thereafter, the upper decorative plate 16 is moved downward toward the lower decorative plate 18, and the pin 70 provided on the upper end surface of the lower decorative plate 18 is inserted into the fitting hole 72 formed in the lower end surface of the upper decorative plate 16. By fitting, the upper decorative plate 16 and the lower decorative plate 18 are attached to desired positions of the frame body 12. Further, the upper decorative plate 16 and the lower decorative plate 18 are fixed to the frame body 12 with screws 39. With the above procedure, the attachment of the heavy object fixing wall 10 to the existing wall surface A is completed.

  As shown in FIG. 1, the large-screen TV X is fixed to the heavy object fixing wall 10 by avoiding the insertion holes 38 and 40 with a dedicated mounting bracket Y provided by the manufacturer for each large-screen TV to be fixed. After attaching to the heavy object fixing wall 10 and inserting the wiring cord or the like from the large screen television X through the insertion holes 36 and 38, the large screen television X is fixed to the mounting bracket Y. At that time, the mounting bracket Y is always fixed to the heavy load mounting plate 14 on the back surface via the upper decorative plate 16 and / or the lower decorative plate 18 with screws or the like. As described above, the case where the large screen television is fixed as the heavy object X on the heavy object fixing wall 10 has been described. However, the same procedure is basically used when other paintings are fixed.

  Note that the heavy object fixing wall 10 according to the present invention can naturally cope with not only the case where the heavy object X is wall-mounted but also the stationary object. For example, as shown in FIG. 15, when the large screen television X is supported from the top surface of the AV rack G or the like using a support stand Z or the like, the large screen television X is prevented from falling down due to an earthquake. A heavy object fixing wall 10 can be used. That is, as shown in FIG. 16, a through hole 90 is provided in the upper decorative plate 16, the lower decorative plate 18 or the heavy load attaching plate 14 of the heavy load fixing wall 10 (when the through hole 90 is provided in the heavy load attaching plate 14. , Through holes 90 are also provided at corresponding positions on the upper decorative plate 16 or the lower decorative plate 18.) A plurality of demon nuts 92 (two in this embodiment) are fitted in advance from the back surface thereof. Then, eyebolts 94 are inserted into the through-holes 90 from the surface of the heavyweight fixing wall 10 and screwed into the demon nut 92 to fix the eyebolt 94 to the heavyweight fixing wall 10. Finally, both ends of the fall-prevention wires 96 attached to the large screen television X are respectively connected to the eyebolts 94.

  Thereby, even if the large-screen TV X is shaken by an earthquake, the large-screen TV X does not fall because it is connected to the heavy object fixing wall 10 via the fall-preventing wire 96 and the eyebolt 94.
