Description

[Detailed explanation of the idea] The present invention relates to an insulating storm door.

Conventional insulated rain shutters connect one panel to the other, fit the ends of both panels into mounting grooves formed in the frame, and then insert foamed synthetic resin with heat insulating properties inside both panels. Its body was made of foam to form an insulating shutter.

By the way, in conventional insulating rain shutters, a water-absorbing synthetic resin foam such as a sponge is closely housed in the mounting groove formed in the lower stile, and then a foam with insulating properties is foamed between both panels. They formed an insulated shutter. If you do not store a sponge etc. in the mounting groove of the lower stile in advance in this way, when filling the foam between both panels and foaming, the edge of the panel and the mounting groove of the lower stile will This is because the foam may blow out from the gap.

However, with the insulated rain shutters formed in this way, rainwater, etc. adheres particularly to the front panel, drips down and enters the mounting groove of the lower stile, and the sponge etc. stored in this mounting groove strips. Absorbs rainwater,
Furthermore, there was a problem that the insulating rain shutters were contaminated.

Thus, the present invention has been devised to address these conventional problems, and will be explained below based on embodiments shown in the drawings.

FIG. 1 is a front view showing an insulating rain door A according to the present invention, and FIG. 2 is a longitudinal sectional view thereof.

Reference numeral 1 indicates the front panel, and reference numeral 2 indicates the back panel. Both panels 1 and 2 are fixed by fitting their ends into mounting grooves 4 formed in the frame 3.

Incidentally, it is preferable that the front and back panels 1 and 2 are formed to have the same shape so that they can be used commonly as the front and back panels. In FIG. 1, a recess 5 is formed approximately in the center of the panel 1. This recess 5
When used as the back panel 2, it becomes an attachment part when attaching a lock. Therefore, when used as the front panel 1, the space between the recess 5 and the lower stile 7 is covered with a cover in order to close the lock attachment hole of the lower stile 7 below the recess 5.

In FIG. 2, numeral 6 indicates an upper stile, and numeral 7 indicates a lower stile.

By the way, both panels 1 and 2 are made of a synthetic resin foam 8 such as a sponge that has water-absorbing properties between their upper and lower ends.
The vertical frames 15, 15 are installed on both sides of the upper and lower frames 6, 7 by fitting them into the mounting grooves 4 of the opposing substantially H-shaped cross sections of the upper and lower frames 6, 7. From this state, the closed-cell foam 9 is filled through the suction port formed in the upper frame 6. Then, the foam 9 is foamed between both panels 1 and 2, and the formation of the heat-insulating storm door is completed.

By the way, in the present invention, a protruding strip piece 10 is provided in the mounting concave groove strip 4 of the lower stile 7 in the middle of the groove width.

A plurality of notch holes 12 are bored in the bottom wall 11 on both sides of the projecting strip 10 at predetermined intervals in the longitudinal direction of the mounting groove strip 4.

Therefore, even if the synthetic resin foam 8 housed in the mounting groove 4 of the lower stile 7 is pressed downward by the heat insulating foam 9 having closed cells, it will not touch the protruding strip 10. This prevents the foam 8 from coming into close contact with the bottom wall 11.

Furthermore, as mentioned above, the bottom wall 11 is provided with notches 12, so that even if rainwater adhering to the panel surface enters the mounting groove 4, it will not penetrate into the synthetic resin foam 8. , from the clearance 13 formed between the foam body 8 and the bottom wall 11, passing through the notch hole 12 and being discharged to the outside. Incidentally, the lower frame 7 in this embodiment is used for a panel in which both panels 1 and 2 can be used both front and back.

FIG. 3 shows a modification of the present invention. In this embodiment, a horizontal piece 14 projecting horizontally is integrally formed at the tip of the protruding strip 10, so that the clearance 13 can be reliably maintained between the foam body 8 and the bottom wall 11.

In addition, since this embodiment is provided with the horizontal piece 14, it is not suitable for a front and back common panel having recesses 5, 5 on both sides as shown in the previous embodiment, and is not suitable for use in a general panel. It is.

Thus, the present invention has the above configuration, and with the insulated rain door according to the present invention, even if rainwater adheres to the front panel and enters the mounting groove 4 formed on the lower stile 7, the rain door will not be affected. In the mounting groove 4, a clearance 13 is provided between the foam 8 and the bottom wall 11, and notch holes 12 are provided, so that rainwater etc. permeate into the synthetic resin foam 8. It can be discharged to the outside without any problems. Therefore, the insulating shutters will not become soiled even after long-term use.
