Abstract

<P>PROBLEM TO BE SOLVED: To provide a TV rack which solves the problem that a conventional TV rack in which the top board is fixed with screwed legs and a bottom plate needs to have through-holes processed corresponding to the total length of the screw and the width of the legs are restricted in terms of material cost and stability and horizontal load capability are structurally hard to be secured. <P>SOLUTION: In a TV rack which has a top box holding an amplifier and a speaker fixed to a bottom plate with screwed legs and can get other electrical equipments inserted, the leg is hollow and structured in folding style comprising a resin sheet and particle board, has screw guide holes at the parts contacting the top box and the bottom board, furthermore, it has a central plate which has a guide hole tapered in the direction of the bottom plate. Assembly workability, stability and horizontal load capability can be secured at low cost and the long screws can be easily inserted/guided because the central plate is attached. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a configuration of a wooden TV rack in which a bottom plate and a leg are fastened to a top portion with a particularly long screw.

  Conventionally, as a configuration of a television rack, a configuration in which a bottom plate and a leg are fastened to a top with a long screw is known. In addition, some assembly legs such as tables are pipe-shaped, and a leg post formed so as to be coupled to the base plate at the lower end and the top plate receiving plate at the upper end is coupled by a long screw and nut ( For example, see Patent Document 1.)

  4 and 5 are a sectional view and a perspective view, respectively, showing the configuration of the first conventional television rack. In FIG. 4, a top box 1 houses equipment such as an amplifier and a speaker, and a TV can be placed on the top, a bottom plate 3 supports a TV rack on the bottom, and a leg 6 is a top box. 1 is fixed between the base plate 3 and the bottom plate 3 to form a space in which AV equipment such as a video deck can be accommodated. The screws 4 fix the bottom plate 3 and the legs 6 to the top box 1. Therefore, since the television rack needs to pass through the legs, the bottom plate, the top and the legs and fasten the top and the bottom plate, it must be fixed with a relatively long screw. Therefore, it is necessary to process a long hole for passing the screw 4 in the leg 6, that is, a hole corresponding to the length of the leg 6. Further, since the width of the leg 6 is restricted from the viewpoint of material cost, it is difficult to structurally ensure stability and horizontal load performance.

FIG. 6 is a perspective view showing a configuration of a second conventional television rack. In FIG. 6, the second conventional television rack is configured such that a space between the top box 1 and the bottom plate 3 is fixed by four legs 4 and can store AV equipment such as a video deck. The second conventional TV rack can secure stability and horizontal load performance with a small amount of material, but it cannot be said that the assembly workability is good.
Japanese Utility Model Publication No.5-1331

  However, in the television rack, it is necessary to process the bolt through hole as a whole through hole corresponding to the length of the screw, and there is a problem that the leg width is restricted from the viewpoint of material cost.

  It is an object of the present invention to provide a television rack that ensures assembly workability, stability, and horizontal load performance at low cost.

  In order to solve the above-described conventional problems, the present invention has a top plate, a hollow structure, a portion that contacts the top plate, and a screw guide hole on the opposite side thereof, and the top plate is attached to the screw guide hole. It is characterized in that it is provided with a leg that is fixed with a screw that passes between them, and has the effect that the bolt through hole can be easily processed and the width of the leg can be set large with a small material.

  Since the TV rack of the present invention has a hollow leg structure, the bolt through hole can be easily processed and at the same time the leg width can be set large with a small material, so that assembly workability, stability, and horizontal load-bearing performance can be reduced at low cost. Can be secured. Since the inserted screw can be guided by providing a central plate at the same time, the insertion of a long screw can be easily induced.

  Hereinafter, the best mode for carrying out the television rack of the present invention will be described in detail with reference to FIGS.

(Embodiment 1)
FIG. 1 is a cross-sectional view of a television rack according to Embodiment 1 of the present invention. In FIG. 1, 1 is a top box, 2 is a leg of a hollow structure, 3 is a bottom plate, 4 is a long screw for fixing the bottom plate and the leg to the top plate, and 5 is a central plate having a guide hole tapered in the bottom plate direction. It is composed. FIG. 2 is a perspective view of the first embodiment. Each leg is fixed with two screws 4 each.

  The leg 2 is composed of a folding method composed of a resin sheet and a particle board, and the four sides on the front, back, left and right of the leg are the parts called the trunk plate on the resin sheet surface. It is assembled so that the board in contact with the top box, the board in contact with the bottom board, and the center board are wound along the grooves provided in the body board. By adopting such a configuration, since the leg has a hollow structure, the bolt through hole can be easily processed, and at the same time, the leg width can be set large with a small material. A guide hole through which a long screw passes is provided in each of the plate in contact with the top box of the leg, the plate in contact with the bottom plate, and the center plate, and the center plate has a shape tapered toward the bottom plate. The TV rack is assembled as a whole by screwing together with the bottom plate with two left and right legs through a long screw to the nut part embedded in the lower part of the top box having an amplifier and a speaker.

  By taking the configuration as described above, assembly workability, stability, and horizontal load bearing performance can be secured at low cost. At the same time, the provision of a central plate provides an advantageous effect that it is easy to guide the insertion of long screws.

(Embodiment 2)
FIG. 3 is a perspective view of the second embodiment. An example in which each leg is fixed by one screw 4 is shown. The number of long screws is reduced to two, and each leg is fixed by one screw 4, and assembly workability can be further improved as compared with the first embodiment.

  The television rack of the present invention can ensure assembly workability, stability, and horizontal load bearing performance at a low cost, and can be applied to applications such as a table requiring load bearing by changing the top box to a top plate.
