2. Description of the Related Art In recent years, for the construction of houses in Japan, wood used for pillars and walls is processed with high precision at the factory or is prefabricated at the factory for high airtightness and high heat insulation. Assembling the assembled units on-site, etc. to seal indoors from the outside, and to uniformly insulate the roof, outer wall, and floor with a heat insulating material such as glass wool or polyurethane. , Buildings that reduce the energy required for heating and cooling, shield noise from the outside, and provide comfortable living in the past.

With the spread of such high-performance buildings,
With the increasing focus on technological development of windows, for which it has been most difficult to obtain a heat insulating effect, windows that can ensure a high level of airtightness and heat insulation are required for cold weather in winter. In Hokkaido and Tohoku, where the environment is severe, the heating costs are reduced in the winter, and in Kyushu, where the heat is hot in the summer, the cooling costs can be reduced. In addition, this high-performance window is also effective in reducing the energy consumption required for the prevention of global warming, and from these viewpoints, demand will increase in the future and performance will be further improved. It is expected that various improvements will be added to.

In addition, at present, double glazing is used to reduce heat transfer indoors and outdoors, and materials with a high thermal conductivity such as aluminum are avoided, and a window frame made of wood or synthetic resin is used for heat insulation. While many tall windows have been developed and started to be provided, shoji doors, which have long been used in Japanese structures, especially houses, also have a certain degree of heat insulation as a characteristic of the material of paper. Since it is an excellent fitting that has both a function of appropriately blocking light and a function of diffusing light, is effective in creating a calm atmosphere, and also has a blindfold function, it is a Western-style room,
It has been adopted as a central indoor fitting in Japan without separating Japanese-style rooms.

In this way, the shoji door, which is indispensable as an indoor fitting in Japan, generally has a glass-covered sash on the outdoor side as to the opening facing the outside.
It will be adopted as one of the double-structured fittings to be built with a predetermined space inside, and when all doors are closed, the plan view of the sliding double-fitting structure in the closed state in FIG. As shown, each sash door (outdoor joinery)
.., 4, 4, 5, 5, ..., One by one, shoji doors (indoor fittings) 82, 82, 83, 83 ,. One shoji door 83,8
When the shoji doors 83, 83 are opened and the central sash doors 4, 4 are further opened, as shown in the plan view of the double sliding door fitting structure in which 3 is opened, the shoji doors 82, 82, 8 are opened.
3,83, ... get in the way, and the central sash doors 4, 4
The crescents 7, 7 provided on either the left or right vertical frame of each are out of reach, and again all the shoji doors 82, 82, 83, 83, ... that are moved to the left and right are placed on the center side. After moving and unlocking Crescent 7,7, shoji door 82,
82, 83, 83, ... should be moved to the left and right sides again, and then the central sash doors 4, 4 must be opened, and vice versa when the crescents 7, 7 are locked. Also shoji doors 82, 82, 8
This caused the inconvenience of having to move 3,83, ....

Such opening and closing operations are repeated almost every day because it is necessary to take in fresh air into the room or send out dirty air to the outdoors in the case of an opening such as a window facing the outside. Originally, only the operation that must be done, improvements and ingenuity have been made along with functions such as heat insulation and confidentiality, of course, as for this operability, it is natural that the custom of building from the past is used. Whether there is any reason why it is socially unacceptable to break or because it is difficult to solve the technical inconvenience by changing the existing building, the existing building is followed as it is. It continues, and there is no sign of improvement yet, and the reality is that it remains in a quiet state.

According to the present invention, in order to meet the above-mentioned needs, intense technical development competition is advancing day and night in the sash / fitting-related industry, and various parts such as the locking mechanism part, the outdoor fittings, the indoor fittings and the sash frame main body. New proposals have been made one after another for the structure, and new products have been commercialized.Including all of them, the operability of the locking mechanism part of the double sliding door fitting structure has been improved in all the related technologies related to sashes and fittings. We have paid great attention to the current situation that no technology has been proposed or put into practice, and it does not hinder rain as usual, and does not cause any problems with the locking function for crime prevention. We started the development and research of the double-jointed door joint structure that can greatly improve the operability of the parts.
As a result of repeated trial and error and numerous trial and experiment over a long period of time, we finally succeeded in realizing a new double sliding door fitting structure. Hereinafter, the configuration of the present invention will be described in detail together with the representative embodiment of the present invention shown in the drawings.

It is not necessary to move the indoor sleeve fittings to the closed state again after moving and unlocking them.Since the unlocking operation of the outdoor fittings can be performed easily, opening and closing operations are performed frequently on a daily basis. By opening and closing the windows and other openings that must be done very smoothly, it is very helpful in reducing household work, and at the same time, such as locking when going out or unlocking when going home. The handling of the opening when it is necessary is especially troublesome. It will be very effective in eliminating the difficulty, and it has excellent features that could not be realized with the 4-pull double-joint structure that has been traditionally handed down. Becomes

Further, as an effect resulting from the fact that the locking mechanism portion such as a crescent is attached to the center side surface of the central side vertical frame of the outdoor sleeve fitting, the unlocking operation of the locking mechanism portion described above is greatly effected. In addition to the major feature of improving, the fittings of each fitting when both the outdoor fittings and the indoor fittings are opened are stored in a state where two pieces are fitted on the left and right of the opening part in the front and back, and the appearance is very good, The feature is that the opening width can also be set to a substantial width by subtracting two fittings.

These characteristics are usually due to the fact that the four outdoor fittings and the four indoor fittings in the double sliding fitting structure are formed to have substantially the same fitting sizes,
In the conventional one, the two middle indoor fittings at the center of the indoor fittings that do not have a locking mechanism part are refreshing to look like they overlap with the indoor sleeve fittings when opened to the left and right, Although the opening width is not narrowed substantially, in the case of outdoor fittings, the vertical frame of the outdoor middle fitting that is the side that contacts the vertical frame of the sash frame main body, Since the locking mechanism part is attached to the side facing the frame part, when each outdoor interior fitting is left open and left open, each locking mechanism part will have a corresponding sash frame body vertical frame part. If the vertical frames on the center side of the outdoor medium-sized fittings are protruded toward the center side of the central frames of the outdoor sleeve fittings and overlap in the front and back, Therefore, it looks bad and the opening width is narrowed accordingly. Had become, they evils is completely wiped, in the open state, the outdoor-side fitting and the indoor-side fitting both in the left and right sides of the opening, both those caused by being housed in shape overlaps back and forth.

On the other hand, in the double sliding joinery structure of the present invention, the vertical frame portion of the sash frame body and the vertical frame portion of the outdoor sleeve joiner which is disposed in abutting contact with the vertical frame portion in a closed state. The draining mechanism part formed between the draining groove part formed on the indoor side and the draining piece part that is loosely fitted in the draining mechanism part drains rainwater that tries to enter the indoor side beyond the vertical frame part. Since it is guided into the groove and reaches the widening gutter at the back, it damps the momentum of inundation and causes it to flow down along the widening gutter, which can reliably prevent rainwater from entering the indoor side. , It is possible to reliably prevent the ingress of rainwater into the interior of the vertical frame of the sash frame body, which may be a concern by arranging the conventional outdoor sleeve fittings inside the outdoor middle fittings. It has the feature of

In particular, in each of the drawings shown as the embodiment, the above-described effect is exhibited evenly, and in the draining structure portion 6 having the structure shown in FIG. Since the buffer gutter portion 66 is formed, the rainwater that enters the draining groove portion 62 side is significantly reduced, and the width dimension of the indoor side piece portion 36 is expanded, so that the indoor side portion 36 Intrusion of water can be prevented more reliably, and the soft draining projection 67 provided on the draining piece portion 65 of FIG. 3 blocks most of the infiltration water at the front part of the widening gutter portion 63. Since the amount of droplets reaching the widening gutter portion 63 is reduced, the width dimension of the indoor side piece portion 36 can be suppressed to be short, the opening width of the sash frame body 3 can be enlarged, and the appearance thereof can be refreshed. To achieve a nice-looking opening The thing that advantage can be obtained.

Further, the water draining structure portion 6 shown in FIG. 4 is adopted. The water draining piece portion 6 which forms two parallel water draining pieces formed to have an E-shaped plane cross section with respect to the vertical frame portion 52.
5 and the sealing piece portion 55, the draining groove portion 6
The rainwater that has entered through 2 is blocked by the sealing piece portion 55, and the sealing piece portion 55 also has a finger for gripping the handle projection 53 protruding from the base of the draining piece portion 65. It also has a function of restricting entry to the indoor side piece portion 36 side, and also has an effect of preventing inadvertent trapping of hands, and in addition, the edging cover formed by molding of soft synthetic resin. Since it is formed integrally with the portion 55, it also serves as an anti-slip and a cushioning material, and has an effect that the function of protecting the fingers can be further enhanced.

As described above, the double sliding door fitting structure of the present invention improves the unlocking operation of the locking mechanism attached to the outdoor fitting to each stage, and remains unattended until now. It is possible to greatly improve the daily operability of the fittings that had been used, and it is also possible to make it extremely advantageous in terms of aesthetics as well. It has a perfect structure against the intrusion of rainwater, and it is easy to assume that it is almost the same as the previous one in combination with the fact that it can be realized with a simple structure. Since it can be manufactured as a low-priced item and can be provided as an inexpensive item, it will be widely popularized in the future, instead of the conventional double-joint pull fitting.
Expected to be used.
