Description

TECHNICAL FIELD The present invention relates to doors, sliding doors, shutters, etc., which are used as fittings for partitioning indoors and outdoors in general houses, storerooms, and the like.

In order to simplify and rationalize the construction of houses, many of the auxiliary functions of openings such as eaves, eaves and other sunshades, rain shields, and adjustment of the length of sunshades have been removed. Therefore, at present, tents, bamboo blinds, etc. are separately provided outside the fittings for the purpose of shielding from the sun and rain, etc., to take over some of the functions that the house has lost.

As a partition in a building, there is a shutter door (see references) that was used in the construction of a shinden in ancient times, but this is not well developed as fittings in a typical house today. Shutters and sliding doors were developed as fittings for partitions, and the difficulty of using them in sunny or rainy weather was perceived as a minor inconvenience.
There are two types of shutter doors, one that covers the opening of the building with a single piece of fittings, and the other that folds down at about half the length of the piece when opened. It can be divided into three types, one is divided into upper and lower parts in the vicinity of the bent position, and the lower part is fixed to the lower part of the opening. The last one was called hanshu and was used for windows. (Squid and fittings are typically referred to as shutter doors when describing the three types of fittings. Doors are also used when describing fittings.) These have the function of eaves and eaves, but are heavy and troublesome to open and close. It seems that it took time and was difficult to handle. For this reason, when temples, shrines, and samurai houses developed and wide openings were quickly needed, it seems that sliding doors that can be easily opened and closed came to be used as partitions.

After World War II, sliding doors were used as storm shutters in ordinary wooden houses for a long time. In addition, shutters with a strong partition function were made of metal, heavy, difficult to handle, and expensive when they were first manufactured and sold. Therefore, it was often used as a partition in the front of warehouses and shops, and it seems that it was not often used as a shutter.

In recent buildings, especially in general wooden houses, most of the main members of the house are processed in a factory and brought to the site for assembly in order to reduce site costs. For this reason, it seems that in some houses, it is common to omit the labor-intensive on-site adjustment and to make the eaves and eaves, which require skill in processing small items, or to make them smaller. Originally, the eaves and eaves were made according to the climate of the building site. It also has the function of extending the dirt floor for opening and closing. Also, the dimensions are determined by the intended use of the room or hallway inside. Currently, such considerations are rarely made, and the only purpose is to firmly partition the inside and outside of the building, including fire resistance. In addition, no consideration is given to flood water with a low water level. Although it is considered as another water stop mechanism, the idea of waterproofing the inside of the building using the same fittings seems to be extremely rare.

Originally, the eaves and eaves of Japanese houses are intended to restore the function of openings such as doorways and windows that originate in daily life, and at the same time, to protect the interior of the building from floods that are not bulky. . As a partition for the opening, we used the type of shutter that was used in Shinden-zukuri and temples and shrines. It's what you're aiming for.

The present invention is attached to a building and consists of fittings (hereinafter referred to as a frame) for supporting a shutter and a door of the shutter, the functions of which are related to each other. The shutter door will be explained based on the two-fold format, but the number of folds can be increased as necessary.
The frame consists of an upper horizontal member corresponding to a long press, left and right vertical members serving as pillars, and a lower horizontal member. A mullion (hereafter referred to as a frame rib) is attached to this member over its entire length. The bi-folding shutters are connected by a rotating hinge, and the rotating shaft of this hinge has a latch structure that can be easily pulled out and inserted. , the door connection can be separated if necessary. When using it as a halves, do not move the lower door. At the connecting part, insert bars are provided on the upper and lower sides to make it impossible to fold in, and if necessary, a single-door shutter is used.
Unlike the width and height of the opening of the frame and that of the shutter, the door is larger, and the two overlap with the frame ribs.
The shutters are suspended from the upper horizontal member by pivoting hinges or pivoting pins. In addition, a newly developed side monkey with a camshaft with an eccentric rotation axis is attached to the lower end of the lower door of the clamshell door. The horizontal monkey is attached to the frame rib of the vertical frame that functions as a mullion. Also, if necessary, the lowest door can be attached vertically with a horizontal monkey. Furthermore, when the width of the door is wide, a picture frame rib on the lower horizontal frame and a crescent lock on the lower part of the door can be attached to prevent them from loosening.

In the present invention, by connecting/separating the shutter and immobilizing the bent part by insert bars, it is possible to change the form of the shutter to a single piece or a double-fold, and a half-shutter, so that the door can be adjusted according to the weather and the purpose of use. can be used properly by
When the weather is fine, it is the provision of shade outdoors, and the adjustment of the amount of daylight and the sun angle indoors. In fittings such as shutters and sliding doors, this was done by changing the area of windows or doorways. Also, in rainy weather, secure a place where you don't get wet, secure an extended passageway, put on and take off your coat to prevent rainwater from being brought into the room under it, and put rain gear in place. It is the provision of a small work place in daily life such as drying the laundry.
The frame ribs are placed between the door and the eccentric shafts of the 8 lateral monkeys in FIG. 1, and the shafts are rotated to bring the door and the frame ribs into close contact. The lower end of the door can be fixed at any position on the frame rib. Also, when the door is located at the lowest end of the frame rib, it is possible to make the inside and outside airtight and to have a waterproof function.
In the closed state, it can be designed to have a high resistance to external forces.
A wide opening can be obtained.
Storage space required for sliding doors or shutters can be eliminated.

[FIG. 2] is a projection view showing a state of opening and closing a double-folding shutter that is one of the embodiments of the present invention; Fig. 3 is a perspective view showing a modified lateral monkey with an eccentric axis;

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in order based on the drawings. First, let's talk about structure and movement. FIG. 1 shows the shutter during opening and closing when in the clamshell configuration. The door 5 is fastened at its upper side to the picture frame rib of section A--A by one or more sets of rotating hinges. The connection with the second door 6 can be rotated using one or more sets of hinges. In addition, the connecting part is provided with an insertion bar so that the hinge does not rotate, and it is possible to make a single shutter door. In the case of FIG. 1, the crosspiece can be retracted and the hinge can rotate freely. The axis of the hinge is an axially moving latch structure. Since the doors 5 and 6 can be separated, they can be moved separately when used as half-barrels. When the door 6 is connected to 5, it bends and hangs down in the conventional type, but unlike the present invention, its lower end is sandwiched between the frame rib of the vertical frame and the lateral monkey, and is stopped at an arbitrary position. When moving to the lowest end of the opening, the picture frame rib and the door can be press-fitted to be airtight and waterproof. If the door is wide, a crescent lock may be used in the middle.
Circular arc lines indicated by dashed lines indicate typical movable directions of the doors 5 and 6 indicated by imaginary lines. Depending on the connection/disconnection of the door and its combination, various movable arc dashed lines are conceivable beyond what is shown here.

Improved livability. : Sun and rain protection, control of indoor solar radiation. Low-water flood protection.
Building a storefront. : Product protection, customer selection, ease of purchase. Ease of passage.
Protection against low-level flooding of in-store merchandise.
Securing a wide opening: Since the door can be flipped up, there is a high degree of freedom in the movement of people and goods.
High resistance to external pressure: When the shutter is closed, it can have a strong resistance to external forces. It can be designed to withstand strong winds, downpours, avalanches, debris flows, and rock-throwing during demonstrations, just like walls.
Storerooms and lockers: Storerooms and lockers installed outdoors make it easy to put in and take out items during rain.
Containers: The length of the container is reduced as the door closure device can be fitted around the inside of the opening. Waterproof and anti-insect effect.
