Description

[Detailed Description of the Invention] The present invention relates to a structure of a lower frame connecting portion in a continuous shutter frame in which a shutter frame is provided for each adjacent window opening, and the ends of each shutter frame are connected.

Conventionally, the structure of the lower frame connection part in a continuous shutter frame was as shown in Japanese Utility Model Application Publication No. 16037/1983.
A guide body is attached to each end of the lower frame of the shutter and both ends of the auxiliary lower frame of the shutter, and an auxiliary lower frame is provided between the ends of the lower frame of the shutter so that the guide bodies face each other, and It is known that connecting plates are secured to each other with screws across both ends of the lower frame of the auxiliary storm door.

However, with this structure, the connection part between the rail of the lower frame of the storm door and the rail of the lower frame of the auxiliary storm door becomes approximately V-shaped, and when the door roller of the storm door transfers from the rail of the lower frame of the storm door to the rail of the auxiliary storm door lower frame. Since the large diameter part of the door roller rides on a pair of opposing guide bodies and the small diameter part of the door roller is separated from the upper surface of the rail, the door roller does not move up and down when passing through the connection part, and the annular shape of the small diameter part of the door roller Since the recess width is larger than the rail width, the door roller may swing sideways.

For this reason, the shutter cannot smoothly pass through the joint between the shutter lower frame and the auxiliary shutter lower frame.

Furthermore, since four guide bodies are required, the number of parts increases, resulting in high cost.

In addition, a pair of guide bodies are attached to each end of the lower frame of the shutter and to both ends of the lower frame of the auxiliary shutter.
In addition to deteriorating the appearance, each guide body protrudes above the top surface of each bottom frame, so the guide body becomes an obstacle when sweeping out dirt, etc. inside the auxiliary storm door bottom frame (that is, between adjacent storm door bottom frames). It gets old and cannot be swept out smoothly.

It has various problems such as.

The present invention was developed in view of the above circumstances, and its purpose is to allow the shutter to pass smoothly through the connection between the lower frame of the shutter and the lower frame of the auxiliary shutter, reduce the number of parts, and reduce costs. To provide a structure for connecting a lower frame in a continuous storm door frame, which has a good appearance and allows dirt, etc. in the lower frame of an auxiliary storm door to be smoothly swept out.
