極めて大なるものがある。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved window for an electric equipment storage box, which allows the inside of an electric equipment storage box such as a switchboard to be viewed from outside. Regarding the structure. 2. Description of the Related Art Conventionally, as a window for an electric equipment storage box, as shown in FIG. 2, a frame member 14 incorporating a transparent plate such as a window glass is provided with an appropriate number of mounting bolts 15 and a switchboard. Alternatively, there is an electronic device storage box that stores instruments and the like attached to a face plate 11 such as a door surface or a lid surface. FIG. 3 is a cross-sectional view showing a peripheral portion of the mounting bolt 15 of the window for an electric device storage box. The frame member 14 is formed by the mounting bolt 15 whose head is stored in the hollow portion 17 thereof.
It is attached to the peripheral portion 13 of the window opening of the face plate 11 with packings 21 and 22 interposed. FIG. 4 is a cross-sectional view of a portion distant from the mounting bolt 15, and FIG.
Except that 5 does not exist, it is completely the same as FIG. [0003] In order to assemble such a window for a storage box for electric equipment, first, a packing 21 is fitted around the transparent plate 16 and attached to the inside thereof. Attach to specified part. At the same time, the packing 22 is similarly attached to the frame member 14. In this case, the mounting bolt 15
It is assumed that the head is previously housed in the hollow portion 17 of the frame member 14 and attached. Then, the frame member 14 to which the transparent plate 16 and the packings 21 and 22 are attached is inserted into the face plate 11 by inserting the mounting bolts 15 into bolt holes prepared in advance, and tightening the nuts with nuts.
Can be mounted and fixed. In such an assembling operation, the packing 2
Since Nos. 1 and 22 are made of a soft elastic material such as synthetic rubber, they have poor rigidity, are easily separated from the frame member 14, and have to work by holding them by hand so as not to separate them. . Therefore, as illustrated in FIGS. 3 and 4, the frame member 14 and the packings 21 and 22 are
4a and 24b adhered so as not to separate. Such a bonding operation requires preparation steps such as applying a liquid adhesive, or cutting and attaching an adhesive tape, and has a problem of poor workability. As shown in FIG. 5, there is a case where a packing 23 in which the packings 21 and 22 are integrated is used, but in this case, there is a similar problem in that the adhesives 24a and 24b are used. SUMMARY OF THE INVENTION [0005] The present invention has been made to solve the above problems, and has been prepared in such a shape that a frame member and a packing can be connected without using an adhesive or the like. In addition, the present invention provides a window for an electric device storage box that can be handled as a single unit during assembly. [0008] The above-mentioned problem is caused by the fact that the elastic packing surrounding the periphery of the transparent plate is interposed at the periphery of the window opening provided in the face plate of the electric equipment storage box. A window for an electric equipment storage box to which a frame member is attached, wherein the rigid frame is
The members include mounting bolts that are attached to bolt holes in the face plate.
With a hollow portion for accommodating a preparative head it is provided, wherein the abutment surface of the rigid frame member of the elastic packing projections are formed, and on its rigid frame member is pushed the protrusion coupling
Fitted freely opening causes is <br/> formed in a shape communicating with the hollow portion, wherein the elastic packing in a state in which the protrusion is fitted is pushed in the opening is affixed to the rigid frame member The electrical equipment storage box window is characterized in that it can be solved. FIG. 1 shows an embodiment of a window for an electric equipment storage box according to the present invention, and FIG. 2 for reference will be described. In the present invention, the structure in which the rigid frame member 14 is attached to the peripheral portion 13 of the window opening 12 provided in the face plate 11 of the electric device storage box by interposing the elastic packing 3 is adopted. This is the same as the case described above. In addition, the mounting structure of the transparent plate 16 such as a window glass is similar to the previous case, in which the peripheral edge of the transparent plate 16 is fitted into the concave groove 31 formed on the inner peripheral side of the elastic packing 3.
It is attached to the rigid frame member 14. A feature of the present invention is that a projection 32 is formed on the contact surface of the elastic packing 3 with the rigid frame member 14, and the rigid frame member 14 has the projection 32
The elastic packing 3 is attached to the rigid frame member 14 in a state where an opening 18 which can be fitted is communicated with the hollow portion 17 and the projection 32 is fitted to the opening 18. Where you are. The rigid frame member 14
The hollow portion 17 is attached to a bolt hole of the face plate 11.
Provided as a part for storing the head of the mounting bolt 15
It is. In order to assemble a window for an electric equipment storage box using the rigid frame member 14 and the packing 3, first, the inner circumferential groove 31 of the packing 3 is fitted around the transparent plate 16. , And this is attached to the inner part of the rigid frame member 14.
Is pushed into the opening 18 of the rigid frame member 14 and connected so that they are not easily separated from each other. Next, the frame member 14 may be fixed to the face plate member 11 using a mounting bolt (not shown) prepared in advance. In this case, the mounting can be performed in the same manner as illustrated in FIG. In this way, according to the present invention, the packing and the frame member can be connected by a simple operation. Also,
Since the integrated packing and the frame member do not have to be separated from each other, the packing and the frame member can be attached and fixed to the face plate member of the electric device storage box with extremely easy operation while holding the window glass. Further, since it is not necessary to use an adhesive as in the related art, there is an advantage that the working time can be shortened and the workability is improved. In this embodiment, a through hole corresponding to the diameter of the mounting bolt may be formed in the packing portion where the mounting bolt provided on the frame member interferes, and the position of the through hole is determined. If the positions of the bolt holes on the face plate material coincide with each other, the positioning of the mounting bolts can be accurately performed, so that there is an advantage that the operation is convenient. Further, in the present invention, the projections 32 formed on the contact surface of the elastic packing 3 with the rigid frame member 14 are provided.
As described above, the rigid frame member 14
Any shape may be used as long as it fits into the concave portion on the side and does not easily separate, but the length of the protrusion 32 in the direction along the circumference of the elastic packing 3 is not particularly limited, and is very small. The shape can be from a simple protruding shape in the case of a short length, to a protruding shape having a certain length, or even a ring-shaped protruding shape continuous around the entire packing. Also, the required number of the projections 32 is not particularly limited, and may be set so that the connection with the rigid frame member 14 is appropriate. According to the present invention, since the window for an electric appliance storage box of the present invention is constructed as described above, the packing and the frame member can be connected by a simple operation, and there is no possibility that they are separated from each other. Therefore, there is no hindrance to handling, and the work of attaching and fixing the window for the electrical equipment storage box becomes easy. In addition, since an adhesive is not required, the working time can be shortened and the workability is improved. Therefore, the present invention has an extremely large practical value as a window for an electric device storage box which solves the conventional problems.
