ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a cabinet.
2. Description of the Prior Art
FIG. 10
is a perspective view for showing a front cabinet of the prior art Television (hereinafter, abbreviated to TV) device. In this figure, the front cabinet
1
is a resin molded product molded through a predetermined die, the front cabinet
1
is pulled out in a direction indicated by an arrow A after being cooled in the die. In this case, in order to prohibit the pulling-out operation, the rails
2
supporting the board are provided with a pulling taper along the direction of aforesaid arrow A, and the width W
1
shown in this figure is slightly smaller than the width W
2
. Further, an electric circuit of the TV device is printed on a printed circuit board, wherein the printed circuit board is held on the rails
2
at both ends, the printed circuit board is inserted into the device while being guided by the rails
2
, and arranged at its predetermined position.
In turn, the gazette of Japanese Utility-Model Laid-Open No. Sho 61-7089 discloses a technology in which parallel supporting rails having engagement portions are integrally molded at both sides of the bottom surface constituting the outer casing and the board supported at the supporting rails is fixed by the board holder capable of being engaged with the engagement portions.
The aforesaid prior art front cabinet had the following problems.
That is, the former was constructed such that both pairs of rails
2
were constructed to have substantially the same length as that of the board and such a long location reduced the cooling speed when the aforesaid molding was carried out. In addition, since the clearances of the pairs of rails were slight due to the presence of the aforesaid pulling taper, the board was tightly held by the rails
2
near the width W
1
when the board was actually inserted into the device, looseness was generated between the board and the rail
2
near the width W
2
, vibration of a speaker or the like of the TV device was transmitted to generate a so-called vibrating sound.
Even with the latter case, the supporting rails are certain long members and it is not possible to make a fast speed of cooling speed when the molding operation is carried out. Further, it is not possible to prevent the vibrating sound from being generated at the location other than the board holder.
SUMMARY OF THE INVENTION
The present invention has been invented in view of the aforesaid problem, wherein it is an object of the present invention to provide a cabinet capable of speeding-up the molding speed of the molded product and reducing a vibrating sound of the completed product.
The cabinet provided by the present invention is a cabinet in which when the board is stored in a casing along a predetermined wall surface, the wall surface is provided with groove-like guide rails capable of inserting the edge of the board from one end to the deeper side and supporting it, and the end portion of the groove-like guide rail can be fixed or removed.
In the present invention constructed as described above, the end portion of the groove-like guide rail to insert the aforesaid board can be fixed or removed and this is separately formed when molded. That is, if the long groove-like guide rails are formed, it is necessary to have a sufficient pulling taper, since it becomes a separate component element, the slight pulling taper is sufficient.
Accordingly, in accordance with the present invention, it is possible to provide a cabinet in which no looseness is generated and a vibrating sound cannot be generated.
More practically, there is provided a cabinet in which a board is supported by groove-like guide rails capable of inserting edges of said board when the board is stored in a casing along a predetermined wall, wherein, the same is comprised of integral molded guide rails integrally molded with the aforesaid casing and supporting a front end of the aforesaid board; and a board holder formed at a lower end in an engageable or fixable manner in such a way that it is vertically installed against the aforesaid wall surface, formed at an upper end with the aforesaid groove-like guide rails in a direction substantially crossing at a right angle with a vertical installing direction and capable of sliding and inserting the aforesaid board under the engaged and fixed state.
In such a configuration as described above, when the board is stored in a casing along the predetermined wall surface, the board can be supported by the groove-like guide rails into which the edges of the board can be inserted. Due to this fact, the integral molded guide rails are integrally molded with the aforesaid casing to support the front end of the board. In addition, the board is also supported by the board holder which is a separate component element of the integral molded guide rail, the board holder can be engaged with and fixed at its lower end in a vertical installed state against the aforesaid wall surface, and its upper end is formed with the aforesaid groove-like guide rail in a direction substantially crossing at a right angle with a vertical installing direction. Further, the board holder enables the aforesaid board to be slid and inserted under a state in which it is engaged with and fixed to the aforesaid wall surface.
That is, the board is supported not only by the integral molded guide rails integrally molded with the predetermined wall surface in the casing, but also by the board holder of a separate component element, so that it is not necessary to make an opposite arrangement of a long rail or the like having a substantial same length as that of the board as the integral molded guide rail found in the aforesaid cabinet, and a speed where the molded product is cooled in the die is made fast.
Accordingly, in accordance with the present invention, it is possible to provide a cabinet in which it is not necessary to construct the long rail having the substantial same length as that of the board as the integral molded guide rail and a speed in which the molded product is cooled in a die can be made fast.
In the specification of the present invention, the sliding direction when the board is slid and inserted is set as a forward or rearward direction of the board and its inserting direction is set from the rear side to the forward side. Accordingly, the front end of the board is an edge of the board where it becomes the forward-most end when inserted. In addition, a size in a direction parallel with the forward or rearward direction at an inserting plane of the board is defined as a length of the board and a size in the direction perpendicular to the forward or rearward direction is defined as a width of the board.
At the integral molded guide rails, it is satisfactory that the front end of the board can be supported, and not only the configuration for molding the guide rails covering the front end edge, but also various kinds of configuration can be employed.
For example, if the guide rails are constituted at both ends in the width direction of the board, both ends in the width direction of the board, both ends in the width direction of the board can be supported under a state in which the board is inserted into the guide rails, the front end of the board can also be supported, resulting in that it is possible to say that in view of this fact the guide rails support the front end of the board. Further, it is also possible to provide a configuration in which both guide rail covering the front end of the board and the guide rail supporting both ends in the width direction are supported.
In this case, it is satisfactory that the aforesaid integral molded guide rails may guide the board and support the board slid and inserted along the predetermined wall surface in the aforesaid casing, and various kinds of configuration can be employed. For example, if both ends of the aforesaid board in the width direction are supported from above and below and the rails for guiding the board to the predetermined position are constructed, the board
