The explanation of symbol

1 Frame door main body, 2 resin plates, 3,3a, 3b lid, 4 peristomes, 5 profiled sheetings, the 5a installation portion, the 5b window shape becomes portion, 7 foam elastomers, 9 cards end plate, 10 through holes, 11 resin plates.

The specific embodiment

Below, describe specific embodiments of the present invention with reference to the accompanying drawings in detail.Fig. 1 is the example about the embodiment of Frame door of the present invention, (a) oblique view for seeing from front face side, (b) oblique view of seeing for side from behind.In the drawings, 1 expression forms the main body of the Frame door of frame shape, 2 expression resin plates, and 3 expression lids, main body 1 forms by metal sheet is carried out punch forming, and the central portion stamping-out in its front forms the big peristome 4 as window.

Resin plate 2 is made template 5 by a plurality of acrylic compounds of same shape and vertically is connected to form, and profiled sheeting 5 becomes the 5b of portion to constitute by the installation portion 5a of left and right end portions with the window shape that exposes from peristome shown in the oblique view of the single profiled sheeting of Fig. 2.Installation portion 5a be butt up against peristome 4 about the end back smooth shoestring, window shape becomes the 5b of portion integral body to heave formation forward with respect to the front of main body 1, and be formed with the curve of R shape at its left and right directions, as a part that becomes the cylindrical shell that extends up and down, heave formation.

Resin plate 2 is that installation portion 5a with profiled sheeting 5 is bonded in the main body the inside of peristome 4 left and right end portions and is connected to form up and down shown in the drawing in side sectional elevation of the peristome that comprises Frame door 4 of Fig. 3.But shown in the A portion enlarged drawing of Fig. 3, the left and right end portions of profiled sheeting 5 is bonded on the main body 1 by foam elastomer 7.And as shown in the figure, the 5b of window portion that resin plate is installed is with respect to main body 1 front projection forward, just as shown in the figure, forms space B between the front of the back of resin plate and main body.And in Fig. 3,8 is the reinforcement framework around the reinforced cut-out portion.

Lid 3 is made of upside lid 3a that is arranged at main body top and the downside lid 3b that is arranged at the bottom, have the width approximately identical and be the front of identical convex shape with resin plate 2, upside lid 3a has from the height of upper end to main body 1 upper end of peristome 4 and forms, and downside lid 3b has from the height of lower end to main body 1 lower end of peristome 4 and forms.In this embodiment, main body 1 to go up following width identical, both sides' lid 3a up and down, 3b forms with identical shape, with the form installation of mutual upset.

Therefore, below only describe, omit explanation downside lid 3b about upside lid 3a.Upside lid 3a is formed with a plurality of slot-shaped through holes 10 that are in its front on left and right directions, be formed with card on top and end on main body 1, and the card on the top of inaccessible lid 3 ends plate 9 simultaneously, and the bottom is not carried out obturation and formed opening.Upside lid 3a is installed in the form on the main body 1, and the resin plate shown in its cross section and above-mentioned Fig. 3 similarly forms space B between upside lid 3a back and main body 1 front.And the space at the upside lid 3a back side and the space at resin plate 2 backs are mutually to connect and form.Have, lid 3 is fixing from back stop on main body 1 of main body 1 by screw again.

Therefore, above-mentioned resin plate 2 and lid 3 are assembled in the Frame door that forms on the main body 1 have formed air flow path shown in the arrow C of Fig. 1 (b), can flow to from the peristome 4 of upside lid 3a at the hot air of inside and air outside is flowed into and take a breath from the peristome 4 of downside lid 3b in outside.

Like this, because of the air of Frame door inboard is taken a breath, the Frame door inboard is difficult for reaching a high temperature, and therefore can suppress the thermal deformation of resin plate, again because of make resin plate forwards projection make the space of Frame door inboard become big, even in framework seamlessly place apparatus can not hinder ventilatory yet.

And, because of needn't on main body, opening the hole of ventilation usefulness, and can not cause weakening of main body intensity, can freely change surface configuration and through hole shape by use lid made of resin body simultaneously, even being set in front, scavenge port also can keep good surface appearance.

And, because of being provided with concaveconvex shape on the whole, resin plate increased intensity, so can also not be difficult for producing uneven phenomenon because of reason easy deformation such as heat.And the bonding part of resin plate also because of being to be situated between can absorb thermal expansion by foam elastomer, can be suppressed at distortion in the Min..

Fig. 4 is the oblique view of other examples of Frame door of the present invention, with the difference of above-mentioned embodiment be, the shape difference of resin plate, resin plate 11 is not established the curve of R type and outstanding forward with respect to the front of main body 1, and window shape becomes portion to form with flat condition.

Like this, if the space, back of space that the window shape of resin plate becomes portion to make to be formed on the lid back and resin plate is interconnected and forms highlightedly to the front, even flat condition or other shapes also are fine.In addition, the lid front forms for being provided with the R curved surface among Fig. 4, but consistent with the shape of resin plate, the front is formed flat condition or other shapes are also passable.

And in the above-described embodiment, resin plate is connected to form with a plurality of acrylic compounds profiled sheetings, but also can use 1 acrylic compounds plate or adopt other synthetic resin to make.And, in the lid through hole be on left and right directions, form slot-shaped, as long as but satisfy air and can flow into or flow out and can take shape arbitrarily.

As above describe in detail, as adopting the invention of technical scheme 1, because of the air of Frame door inside is taken a breath, the Frame door inboard is difficult for reaching a high temperature.Thereby can suppress the thermal deformation of resin plate, again by make resin plate forwards projection enlarged the Frame door inner space, can not hinder ventilatory even in framework, seamlessly place equipment yet.

And, do not use the hole because need on main body, not open ventilation, so can not weaken main body intensity, can more freely change the shape of surface configuration and through hole by using the lid made of resin body, even being arranged on the front, air-vent also good surface appearance can be arranged.

And, because of being designed to concaveconvex shape on the whole, resin plate increased intensity, so be difficult for the distortion that generation causes because of reasons such as heat.

As adopt technical scheme 2 described inventions, on the basis of the effect of the scheme of possessing skills 1, the resin plate bonding part also can absorb thermal expansion, can be Deformation control at minimum.
