The specific embodiment

Below, describe specific embodiments of the present invention with reference to the accompanying drawings in detail.Fig. 1 to Fig. 3 represents an example of relevant Frame door of the present invention, and Fig. 1 is an oblique view, and Fig. 2 is the back side oblique view on its top, the strabismus decomposition figure at the position that Fig. 3 represents for Fig. 2.

In the accompanying drawings, the 1st, the framework of Frame door, the 2nd, resin plate, the 3rd, lid.Framework 1 is by with metal sheet bending and punching molding, has smooth front 1a and 4 limits on every side and forms up and down each side to the back bending.1a is provided with the peristome that serves as window 4 that slightly is rectangle from top to bottom in front, and this peristome 4 forms in the central authorities of framework, and the front 1a of framework 1 is symmetrically formed up and down.

In addition, resin plate 2 uses resin plates, with the big slightly formation of ratio open portion 4, and is provided with adhesive portion 2a to the peristome end of framework at its periphery.

Though lid 3 is arranged on the top of

framework

1 and 2 places of bottom, but use the other way around with the lid of same shape.Therefore, only describe below about upper cover.When lid 3 has the width identical with peristome 4, have from the height of upper end to the upper end of door of peristome 4.And, be designed to that its central portion is outstanding lenitively forwards to form curvature, simultaneously, the front that is formed by curved surface has a plurality of slot-shaped horizontal wide grooves 6 that are arranged in parallel.And, have smooth top panel 5 at an upper portion thereof, inside side 3 places are provided with and are used for fixing the screw 7 that is installed on the framework 1, simultaneously framework 1 on should the position of screw 7, be formed with screw insertion hole 8.

In addition, the bottom of lid 3 is provided with the retention tab 9 that keeps resin plate 2.Give prominence at the framework back when retention tab 9 forms lid 3 is installed on framework 1, and form L shaped section and make it clamp the resin plate 2 that is installed on framework 1 back.Simultaneously, the upper and lower end parts at the peristome 4 of framework 1 is formed with the breach 10 that is used for inserting logical retention tab 9.
