Frame door

Abstract

The present invention provides a frame door having a structure in which a resin plate closing a window portion is not easily deformed. The upper and lower fronts of the opening (4) of the main body (1) are provided with a resin cover (3) that protrudes forward relative to the front of the main body (1), and the cover (3) A certain space is formed between the back and the main body (1). The opening (4) is covered by the resin plate (2), and the part of the resin plate (2) exposed from the opening (4) is also formed to protrude forward relative to the front of the main body (1), and the cover ( The space formed at the back of 3) and the space at the back of the resin board (2) communicate with each other. The front of the cover (3) is provided with a plurality of penetration holes (10).

Description

technical field [0001] The present invention relates to a frame door mounted on the front of a frame such as a cabinet or a box for accommodating electronic equipment, and more particularly to a frame door having a window partially provided with a resin plate. Background technique [0002] Among existing frame doors, a frame door having a window formed of a resin plate such as Figure 6 It is formed as shown, and is composed of a metal frame-shaped main body 21 and a resin plate 23 installed to close the opening 22 provided at about the center of the main body 21. The installation of the resin plate 23 is mainly performed by Figure 6 to Figure 8 The three ways shown are implemented. [0003] Figure 6 It is a cross-sectional explanatory view of the fixing part of the resin plate 23. The resin plate 23 is held and installed by the holding member 24 having a U-shaped cross section provided around the opening 22 which is a window on the inner surface of the main body 21. The ...

Problems solved by technology

[0006] However, in such Image 6 In the shown fixing method, although the resin plate is not easily deformed because it can absorb the dimensional changes caused by the thermal expansion of the resin plate 23, rubber bodies 25 have to be installed on each side of the resin plate 23, which not only takes time but also requires time for assembly. Increased costs

And, if Figure 7 In the form shown using the gripping member 28, since the resin plate 23 is only partially gripped, the resin plate 23 tends to undulate, and it is easy to see thermal deformation and the like.

[0007] and, Figure 8 The shown method of using the reinforcing frame 29 for direct fixing, because the four sides of the resin plate 23 are completely fixed, can suppress the occurrence of the undulation phenomenon at the end of the resin plate 23, but it is still easy because the fixed part cannot absorb thermal deformation. out of shape
