A spacer strip 40 is fixed to the other hinge frame strip 20 by a rivet 34, and the rest is configured in the same manner as in the above-mentioned example. Therefore, the same reference numerals are given and the description thereof will be omitted.

Although the illustrated example is as described above, these composite connection hinge frames are, for example, rivets or screws which are screwed into the hollow portion so as to be tapped in the hollow portion when they are detachable. By arranging them alternately so as to be one side, it becomes possible to easily connect each panel in a bellows shape at a place of use, etc. Also, if one or both of them are used at a predetermined position, a plurality of unitized panels are connected in advance. Can be connected in the same way. Also, for example, in order to perform this connection within the plane of the shutter frame, etc., by avoiding the connection site where the door rollers running inside the frame are installed and performing the connection at the connection site that escapes out of the frame, the shutter will be released. This is convenient because the panel connection can be easily performed in the state of being housed in the frame.

The concave-convex engaging means between the connecting groove and the connecting protrusion is
For example, it is possible to use one protrusion each, or one protrusion and the other multiple protrusions, and it is preferable to interpose them. For example, the spacer strip and the side where the spacer strip is not fixed to the metal fittings. Pressing force by interposing between the connecting grooves or connecting ridges in the hinge frame, or by applying adhesive means so that the fixing depends on this, or by elastically press-fitting the spacer It is also possible to fix with this, and the necessity and means of fixing at this point can be appropriately established.

Further, according to the present invention, the other connecting projection is formed into an L-shape to form a spacer section and an overlapping portion of both hinge frame sections, and by fixing the metal fitting. You may make it fix these integrally.

Moreover, the positional relationship of the hinge strips can be reversed from the panel frame side, and the opening angle of the groove to be fitted on the panel frame side can be increased to, for example, about 100 °. If a plurality of hinge connecting frames are used as in No. 247682, it is possible to change the extension angle in the non-folding direction and perform the connection capable of dealing with the curved opening surface. In the practice of the present invention including the above, each concrete shape and structure of the hinge frame strip, the connecting groove strip, the connecting projection strip, the spacer strip, the metal fitting fixing means or the concave-convex engaging means, their relations, dimensions, The usage and the like can be variously modified without departing from the gist of each invention, and the invention is not limited to those illustrated and described above.
