Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a top door shutter installed in an opening of a building.

(Background Art) Conventionally, this type of hanging door shutter has been disclosed in Japanese Examined Patent Publication No. 50-27663.
No. 56/22384, etc., the center line of the shutter main body is aligned with the center line of the shutter frame, and the shutter main body is inserted and guided in the opening groove of the shutter frame. It was a thing.

However, in these conventional door shutters, in order to open and fold the shutter body, it is necessary to remove the shutter frame from the inserted state, and therefore, the shutter frame is folded at the one end in the longitudinal direction. The door pocket with the required length and width partially cut out is limited to a certain position, and if an airtight means such as an airtight material is interposed between the shutter frame and the shutter main body, friction during feeding traveling to the door pocket will occur. Since the resistance becomes large, it is difficult to provide this, and even if this could be done, it was structurally extremely difficult to install the airtight means in the door pocket part where the notch was removed.

For this reason, in the conventional door shutter of this kind, the door pocket position is fixed, and changing it requires construction of the building frame, and since the airtightness is insufficient, the installation location is a warehouse, factory or inside the building. It had to be limited to places where airtightness such as openings was not required.

(Object of the Invention) The present invention has been made in view of the drawbacks of the conventional shutter of this type, and the folding position can be arbitrarily determined, and its change is easy, and the airtightness can be ensured. It is an object of the present invention to provide an upper hanging door shutter that can dramatically expand the installation location.

(Structure of the Invention) In accordance with the above object, the present inventor has conducted extensive studies, and as a result, basically eliminates the relationship between the shutter main body and the shutter frame in the conventional door shutter, and superimposes the shutter main body and the shutter frame. The present invention has been completed by discovering that it is extremely effective to have a structure in which a press-like relationship is formed in which the shutter body is connected to each connecting frame portion. In the above-mentioned shutter main body, the shutter frame is supported on the shutter frame, and the shutter frame is provided with a series overlapping contact portion with the shutter main body through an upper hanging door roller horizontally projecting inward of the connecting frame in the upper or lower horizontal frame. Between the connecting frames, the left and right end portions of a plurality of parallel doors that are foldable on the front side of the contact portion are rotatably connected, respectively, and between the shutter body and a series of overlapping contact portions. This is completed as a gist of an upper hanging door shutter, which is characterized in that an airtight means is interposed so as to cover the entire length.

By the way, although not shown above, in the present invention, all or a predetermined number of connecting frames are divided into two or three in the traveling direction, and these can be separated and connected (for example, various detachable metal fittings, locks, etc. may be used. It can be easily understood from the above description that the shutter can be opened and closed at any position.

Although not essential to the present invention, when the link-shaped reinforcing member is provided, the shutter main body receives a closing force uniformly in the closing direction, so that all the parallel doors are simultaneously folded from the upper and lower horizontal frames. Once started, it can be opened and closed very lightly.

Since the present invention is an upper door shutter, the upper structure is essential, but the lower part can be selectively implemented or arbitrarily changed. Therefore, using the shutter frame without the lower horizontal frame,
A pin-shaped engaging portion provided on the connecting frame may be engaged with a guide groove formed on the floor surface, and a tongue-shaped airtight member may be slidably attached to the lower end of the shutter body, if necessary.

The parallel doors of the shutter body are, for example, 4 sheets, and each of them is connected by a hinge, or 2 of them are the other 1/2.
The width can be changed according to the design. Of course, the shape and material of the hinge to be used are not limited, but it may be desirable to separately provide airtight measures to this portion in some cases. The parallel door is rotatably connected to the connecting frame. In the present invention, the connecting frame supports the shutter main body in a suspended manner. Therefore, its shape may be the same as the hinge. It is possible.

On the other hand, the overlapping contact portion can be formed by directly or slightly forming a step on one side surface of the horizontal frame. In this case, it is preferable that a rolling element or a sliding element is provided so as to project inwardly above and slightly above and below the shutter body, and the rolling element or the sliding element is supported by a horizontal frame so as to be suspended.

The airtight means interposed between the superposition contact portion and the shutter main body is preferably provided over the entire length. Therefore, various airtight materials such as mohair and packing are used singly or in combination, or
It may be formed as necessary and the specific means is not limited to this.

When the reinforcing member is provided, it can be formed into a rhombic shape or can be connected to be expandable and contractible in the vertical direction, and the engagement with the lateral frame and the shutter body is performed over its entire length. May be On the other hand, although the groove engagement is simple, the protrusion of the lateral frame may engage with the engagement groove of the reinforcing member in a detachable manner at this time.

The present invention is not limited to the above embodiments and description examples, and it is needless to say that various specific shapes, structures, materials, addition of related parts, and the like can be made without departing from the spirit of the invention.

(Effects of the Invention) The present invention allows the shutter main body to be supported on the shutter frame by suspending the shutter main body at each connecting frame portion, and the shutter frame is provided with an upper hanging door roller horizontally projecting inward in the connecting frame at the upper or lower horizontal frames. The shutter body has a series of overlapping contact portions with the shutter body, and the shutter body has a plurality of parallel doors left and right foldable freely foldable on the front side of the contact portion between the connecting frames. The main body can be removed from the shutter frame at any place, and it is not necessary to remove the cutouts of the horizontal frame in the door pocket part like the conventional door shutter of this kind. It is possible to omit the fixed provision of the door pocket part and eliminate the left-right hand, and even if it is provided, the left-hand hand can be easily made free.

Further, since the airtight means is interposed between the shutter main body and the series of overlapping contact portions so as to extend over the entire length thereof, it is possible to continuously ensure airtightness on the rear side of the shutter main body, and in the door pocket portion, Since there is no notch removal that obstructs the airtightness, it is possible to easily and surely perform the airtightness, especially in the upper or upper and lower lateral frames, which has been impossible in the past.
