The shutter frame C is a shutter body B.
Formed slightly larger than the extended width dimension of the slide frame 1
1 is slidably fitted in the hanging-side vertical frame 21, each upper door roller 16 is rotatably mounted on the support rail 27 of the upper frame 26, and is mounted on the guide groove 31 of the lower frame 28. By inserting the lower sliders 18 into the shutter frame C, the shutter main body B is supported in a bellows-like manner so as to be foldable and extendable so that the horizontal pull shutter A is configured.

At this time, a slide frame retaining device D is provided between the suspension-side vertical frame 21 and a slide frame 11 slidably fitted therein, and the shutter is prevented by this retaining device D. The slide frame 11 is prevented from coming out of the hanging base side vertical frame 21 of the frame C, while the hanging base side vertical frame 21 and the slide frame 11 are sealed.

That is, in this embodiment, the slidable loose fitting of the slide frame 11 with respect to the hanging-side vertical frame 21 absorbs a dimensional error with the lateral width of the building opening, and slide frame 1
The slide frame 11 is received by a cushioning member 22 such as a cushion material and a spring provided on the hanging-side vertical frame 21, and the shutter frame B is opened when the shutter body B is opened. By applying a reaction force to the main body B side, the folding of the shutter main body B is guided and promoted, and the opening thereof is facilitated. Therefore, the slide frame 11 opens the suspension-side vertical frame 21 by the reaction force. It is necessary to prevent this, as it may escape each time.

The slide frame retaining device D includes a retaining projection 12 projecting from the end of the suspension frame side slide frame 11 in a direction intersecting with the sliding direction, and a vertical frame at the suspension side which receives the slide frame 11 slidably. A vertical frame that is integrally attached to the vertical frame 21 via a hinge 40 located inside the end of the side wall 23 of the frame 21, defines the receiving opening 24 of the slide frame 11, and enlarges and opens the receiving opening 24. It is provided with a rotation stopper 25 which can be raised and lowered freely.

That is, in this embodiment, the retaining projection 12 of the slide frame 11 is a fin-like member which is provided at the end of the slide frame 11 on the vertical frame 21 side so as to project in the non-folding side direction orthogonal to the sliding direction. , Rotating stopper 25 of the vertical frame 21 on the hanging side
Stands up so as to face the retaining projection 12 and forms a receiving opening 24 for the slide frame 11, and, if necessary, falls down by the hinge 40 into the hanging side vertical frame 21 to receive the opening. It is designed so that it can be tilted up and down to expand and open 24.

The turning stopper 25 is raised and lowered through a hinge 40. In this example, the hinge 40 is
The C-shaped fitting projection 41 having the entire length in the longitudinal direction is provided on the inner surface of the side wall 23 of the hanging-side vertical frame 21 via the connecting wall 42, and the fitting projection 41 is fitted to the end of the rotation stopper 25. It is based on a full aluminum hinge provided with a C-shaped fitting strip 43 which is also provided along the entire length in the longitudinal direction so as to be fitted. The fitting 43 is
By making one end thereof abut on the connecting wall 42 of the fitting projection 41, it stands upright on the side wall 23 of the hanging-side vertical frame 21 at a right angle, while the other end abuts on the connecting wall 42 as well. So that it falls parallel to the side wall 23,
It has a rotation range of °.

Accordingly, by raising the rotation stopper 25, the slide frame 11 is prevented from being pulled out and sealed in a positional relationship facing the slip-off preventing projection 12 of the slide frame 11, and on the other hand, by being turned over, The receiving opening 24 is enlarged and opened so that the slide frame 11 can be loosely fitted into or removed from the hanging-side vertical frame 21.

In this embodiment, the slide frame retaining device D is provided with a fixing means, and the rotation stopper 25 maintains the upright state when the slide frame 11 is loosely fitted in the hanging-side vertical frame 21. In this way, the fixing means is a screw 44 which is screwed into the fitting projection 43 from the fitted piece 43 at an appropriate position in the longitudinal direction. As a result, the rotation stopper 25 is affected by vibration, wind pressure in the case of the outdoor side, etc.
It is intended to prevent the slide frame 11 from accidentally escaping from the hanging-side vertical frame 21 by falling over.

In the horizontal pull shutter A having the above-mentioned slide frame retaining device D, the shutter frame C is provided in the building opening.
After fixing the shutter body B, the shutter main body B is hung on this, and the suspension base side slide frame 11 at the end is slidably fitted in the suspension base side vertical frame 21, and then the rotation stopper 2 of the vertical frame 21
5 is erected so that the screw 44 of the fixing means maintains the erected state, and when repairing the panel of the shutter body B due to damage, for example, the fixing means is released and the rotation stopper 25 is turned over. The shutter body B can be removed.

Reference numeral 17 in the figure is a slack stopper provided on the escape hinge frame 14, and 30 is a guide groove 31 for guiding the lower slider 18 by allowing it to be fitted into and removed from the outer frame 29 of the lower frame 28.
And an inner frame used to make the lower frame 28 flat when the shutter main body B is opened by forming the above-mentioned
2 is the stainless steel floor material, and 33 is the airtight material provided on the shutter frame C and the rotation stopper 25, respectively.

Although the illustrated example has been described above, in the practice of the present invention, it is generally desirable that the rotary stopper be maintained in its upright state. Means may be provided, or urging means for urging the rotation stopper in the upright direction by a spring may be provided. However, for example, when using the above-mentioned aluminum whole hinge, if the rotation stopper is prevented from easily rotating due to the dimensional relationship between the fitting projection and the fitted fitting,
The installation of these fixing means or biasing means can be omitted.

Further, the retaining portion of the slide frame is integrally formed and installed on the slide frame, and a cushioning member such as a leaf spring is interposed between the retaining portion and the rotation stopper to prevent the retaining portion and the rotation stopper. To prevent direct collision with the hinge, to use hinges that are partially installed hinges such as flag hinges, and to arrange the retaining device so that it is located on the folding side of the slide frame on the hanging side or both inside and outside the room. In carrying out the present invention, including installation, etc., the concrete shapes of the shutter body, shutter frame, slide frame, retaining projection, vertical frame on the hanging side, and rotation stopper,
