Description

Description: TECHNICAL FIELD The present invention relates to an opening frame device such as a folding door, a sliding door, or a movable partition in a room, which is installed in an opening of a building or the like, and is particularly long. The present invention relates to an opening frame device for a continuous door in the case where a plurality of these door bodies are associated with the opening of the.

[Prior Art] Conventionally, in the opening frame of the folding door or the like, the upper and lower ends of the door body are inserted into the guide groove to guide the opening and closing.

Here, in such a conventional device, it is necessary to partially cut out the side wall of the groove in order to separate the insertion edge of the door body from the guide groove at the removal position of the door pocket portion of the folding door or the upper sliding door, for example. Correspondingly, if it is a buried lower frame, it is necessary to dig down the floor surface of the building etc. one step according to the above-mentioned cutout depth (for example, under the horizontal folding type folding door or the upper hanging type sliding door). (In the case of a frame), it is not possible to completely embed it in the peripheral wall of the opening, etc. with an upper frame, etc., and it must be projected inward in the opening surface by about the notch depth of the guide groove. It was

In addition, the width of the door pocket part in which the floor surface is dug down is not only the folding width of the door body, but also a margin width for introducing this into the lower frame groove while further extending the door body panel It takes two sheets), and the plan view shows that the floor is dug into a trapezoidal shape with a relatively wide margin in the hypotenuse.

[Problems to be Solved by the Invention] However, when the floor surface is dug down to form the door pocket portion in this way, there are obstacles to traffic (a reduction in the actual opening width), rain problems, and the appearance is simple. Will be lacking. Also,
When the upper frame or the like is projected from the peripheral wall of the opening in the in-plane direction of the opening, there is a problem that the substantial opening area of the opening is reduced in addition to the problem of appearance.

In order to improve the problems of the conventional opening frame device, the present inventors set the opening frame as a separate structure of the fixed frame part and the movable frame part, and moved the movable frame part up and down through the fitting groove of the fixed frame part. Although a frame device has been proposed, the present invention is a further improvement of the opening frame device having such a movable frame part, and in particular, a plurality of door bodies are connected in a relatively long opening / closing width so that they can be separated and opened / closed. In this case, it is possible to maintain the opening of the opening partially closed (or, conversely, to partially open it), and also to raise and lower the movable frame easily. The purpose is to provide.

[Means for Solving the Problems] The present invention has been completed in view of the above object, and in a continuous door having a plurality of door bodies that can be separated and opened / closed, an opening width is provided in each of the fitting insertion grooves of the long fixed frame portion.

Even if the joint portion is pressed and the operation of the movable frame portion is limited only in the vertical direction by a guide block or the like, the movable frame portion moves vertically while interlocking with the door body.

Further, although it is required to move in the opening / closing direction, for example, even if one end of the small plate-shaped arm is rotatably fixed to the fixed frame portion and the other end is rotatably fixed to the movable frame portion, the lifting device can be configured easily. it can.

Of course, the number of doors and movable frame parts can be freely set by two or more, and the selective engagement part is also provided in any movable frame part except the movable frame part located at the end on the door-stop side. It is possible. Here, when the plurality of movable frame portions are provided with the selective engagement portions, each of them may be disengaged from the preceding door body and engaged only with the specific succeeding door body in charge.

Of course, such an opening frame device may be provided in the upper frame portion of the serial door.

Although the embodiments are configured as described above, the present invention does not violate the gist of the invention, as long as the door body, the serial door, the fixed frame portion, the fitting groove of the fixed frame portion, the movable frame portion, the lifting device, the preceding door body, The specific shape, structure, size, material, number, arrangement and relationship of the subsequent door body and the selective engagement portion, and the relationship thereof, and the type of the continuous door can be variously changed, and are not limited to the above-mentioned embodiment. Needless to say.

EFFECTS OF THE INVENTION Since the opening frame device for the serial door of the present invention is configured as described above, the fixed frame part is installed, for example, in an embedded form on the floor surface or wall part of a building by adopting the movable frame part. When the door is opened, the movable frame portion is lowered into the fitting insertion groove of the fixed frame portion, so that the floor surface is specially dug down to form a recessed door bag portion, or the upper frame is surrounded by a peripheral wall or the like. It is not necessary to fix the opening frame in a protruding state, and it is possible to set the opening frame while ensuring a substantial opening width or a substantial opening area of the opening.

In particular, the movable frame portion of the device of the present invention is made up of a plurality of partial lengths in the opening width direction, each of which is provided with an elevating device so that it can be independently raised and lowered, and the movable frame portion not located at the end of the door stop side has a leading door. A selective engagement portion that is disengaged from the body and that engages with the succeeding door body is provided, and the closing force thereof is transmitted to the lifting device so that the movable frame portion is selectively interlocked with the succeeding door portion. Therefore, even if only a part of a plurality of doors that are connected in series is closed, it is possible to engage the movable frame part with the closed door to provide vibration control, while the remaining open parts are movable. The frame portion is housed in the fitting groove of the fixed frame portion so that there is no hindrance to traffic if the opening frame is the lower frame portion, and the opening area is wide in the upper frame portion, and the appearance is simple.

In this way, this device is an opening frame device in which the door body can be disengaged by raising and lowering the movable frame part, and when this is adopted as a continuous door, it is possible to uniformly operate the entire opening and closing width. Instead, it becomes possible to individually disengage the movable frame portion and the door body in accordance with the partial closure (or the partial opening).

Further, each movable frame part having a partial length in the opening width direction can be manufactured relatively light even in a long continuous door, and its operation can be made light.
