Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a folding door such as a horizontal shutter and a partition,
Particularly, it relates to a folding door with an independent opening / closing door.

[Prior Art] This type of folding door has an opening having a folding door body in which panels are foldably connected in a bellows shape, and an opening corresponding to the extension length of the folding door body in which the folding door body is openably and closably mounted. A frame is provided, for example, a folding part having a notch opening in the room direction is provided on the upper and lower frame longitudinal hanging sides of the opening frame, and the folding part is opened and closed so as to be folded and housed in a bellows shape. ing.

[Problems to be Solved by the Invention] However, in this case, even when a small opening is obtained on the door end side for the entry and exit of a person, the folding door body is pressed to move the entire folding body toward the folding portion to open it. In addition, it is necessary to pull the folding door body to close it, and the larger the opening width of the opening frame, the more force is required to push and pull the folding door body. In particular, it is particularly troublesome when the folding door body is closed in the case of rain and it is necessary to open and close the door every time a person comes in or goes out.

The present invention has been made in view of such circumstances, and a problem to be solved by the present invention is to provide a folding door in which people can easily enter and leave.

[Means for Solving the Problem] According to the present invention, in accordance with the above problem, a part of the opening frame is arranged in series with the folding door body at the door end side so as to be closed by a single door. By using the front end frame of the folding door body as the vertical frame for the door, and by making it double as this, it is possible to allow people to enter and exit by opening and closing the folding door body as much as possible. In addition, by opening the folding door body and the door, it is possible to obtain a wide and fully open opening without a partition or obstacle, that is, the present invention makes it possible to fold the panel in a bellows shape. One side of the connected folding door body, an opening frame having an opening wider than the extension length of the folding door body in which the folding door body is openably and closably mounted, and a vertical frame of the opening frame on the folding door body hanging side. The end is rotatably fixed Folding with a single opening / closing door, characterized in that the other end is folded and the door frame of the door body is used as a vertical frame for a door stop The present invention relates to a door and serves as a means for solving the above problems as the gist of the invention.

[Embodiment] The present invention will be described in more detail with reference to the drawings showing the following embodiments. The folding door A is a folding door A in which the folding door body 1 is attached to the opening frame 7 so as to be openable and closable. On the other hand, a door 18 that can be opened and closed independently is provided in the opening frame 7.

The folding door main body 1 is formed by vertically connecting a large number of panels 2 in a bellows-like foldable manner. In this example, this connection is made by arranging the upper hanging door rollers alternately arranged between the panels 2. In addition, a traveling hinge frame 3 for suspending traveling, each of which has a swinging piece (not shown) at the lower end, and a swinging piece (not shown) at the upper and lower ends that escapes from the opening frame 7 to the inside or the outside when folded. The escape hinge frames 4 for escape are provided respectively.

The folding door body 1 is attached to the opening frame 7 by mounting the upper hanging door roller of the traveling hinge frame 3 on the guide rails of the upper frame 8 and setting each swinging piece at the lower end of the lower frame 9 to the lower rail 9. It is carried out by engaging the guide 17 and hanging it up and down. The opening and closing is provided on the side of the upper frame 8 in the longitudinal direction of the hanging side with a cutout portion corresponding to the total width of two panels and the folding margin. , The folding hinge frame 4 is provided at the corresponding position of the lower frame 9 with the guide 16 dedicated to the traveling hinge 3, and the escape hinge frame 4 is made to escape from the opening frame 7.

At this time, the opening frame 7 is assumed to have an opening wider than the extension length of the folding door body 1, and the door 18 is
Folding door main body 1 One end is rotatably fixed to a vertical frame 11 on the non-hanging side, and the other side end is a folding door main body 1 with the door end frame 6 of the folding door main body 1 as a vertical frame per door. They are arranged in series.

In this example, the door 18 is a single panel body that uses two panels that are the same as the panel 2 of the folding door body 1 in order to unify the appearance, and the same frame as the hanging frame 5 and the doorframe 6 at both ends. The frame members 22 and 24 are used, and one of the frame members 22 has a bearing 20 and a rotary shaft 23.
A hinge mechanism is provided to allow free rotation, and the other frame member 23 that prevents rotation with respect to the panel is provided with an L-shaped door contact member 25. It is assumed that the frame member 22 is inserted into the vertical frame 11 of the opening frame 7 and is fixed to the vertical frame 11 by screws 22 so that the frame member 22 can be freely rotated. The door end piece 6 of 25 is abutted against one of the indoor and outdoor surfaces of the door end frame 6 so that it can be contacted with the door end frame 6 so that the door end frame 6 is also used as a vertical frame of the door end frame 6. 18 is the folding door body 1 by setting the position in the opening frame 7 to the front-rear center position.
In addition to the above, the door contact member 25 and the door end frame 6 are abutted against each other and the relationship between the door end frame 6 and the vertical frame of the door end frame is secured.

Although illustration is omitted, an appropriate locking device such as a sickle lock is provided between the door end frame 6 and the door 18 to further enhance the function of the door end frame 6 as a vertical frame for a door contact. The folding door A can be locked.

In the drawing, 10 is a vertical frame of the folding door body 1 on the hanging side, 13 is a folding door body receiving groove of the upper frame 8, 15 is a lower frame substrate of the lower frame 9, and 19 is a vertical frame of the panel 2 integrally having a bearing 20. , 27 is a cushion member provided on the door contact piece 26 of the door contact member 25, 28 is a door catcher provided on the upper frame 8, 29 is its leaf spring, and 30 is elastically in the leaf spring 29 of the door catcher 28. The fitting members 31 on the side of the door 18 that can be fitted and removed are the diamond-shaped fitting projections, respectively.

Although the illustrated example is as described above, in carrying out the present invention, the specific structures, shapes, materials, and their relationships of the panel, the folding door body, the opening frame, and the door are related to the gist of the invention. As long as it does not conflict, it can be variously modified and is not limited to the above description.

EFFECTS OF THE INVENTION The present invention has a folding door body in which panels are foldably connected as described above, and an opening having a wider width than the extension length of the folding door body in which the folding door body is openably and closably mounted. A frame and a folding door body of the opening frame. One side end is rotatably fixed to a vertical frame on the non-suspending side, and the other side end is folded, and the door end frame of the door body is used as a door stop vertical frame. It is characterized in that it is provided with a door that can be opened and closed independently and is arranged in series, so that when the folding door body is closed, people can enter and exit by opening and closing the door independently, and this is made as easy as possible. In addition, by opening the folding door body and the door, it is possible to obtain a single wide open opening with no partitions or obstacles. In addition, the series arrangement ensures the sealing performance when closed and the appearance is good. We can provide folding doors with opening and closing doors It
