BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door structure, and more particularly to a door structure which is opened by moving a door housed in an opening having a lateral frame along the opening surface or at a right angle to the opening surface. Thus, the present invention relates to a door structure in which the door moves intermediately between a sliding door and a swing door and is attached to a place with a narrow frontage, so that the same airtightness and watertightness as a sliding door can be obtained.

[0002]

2. Description of the Related Art Various types of doors are attached to stores, ordinary houses, schools, hospitals, and other buildings, but generally, hinged doors and sliding doors are generally used. The hinged door has an axis A at the outer end portion of the double doors 1 and can be opened by pushing or pulling like the floor hinged door shown in FIG. 9 which is often used in stores. Since it is necessary to make a large gap between the door frame and the door frame, there is a problem with the heat insulation effect and the soundproofing effect due to the poor airtightness. Also, when opening and closing the door, there is a difficulty that when it is pushed and opened, it obstructs the path of the person on the other side of the door, and when it is pulled and opened, it obstructs the path of the person on the front side of the door. .

On the other hand, the sliding door does not get in the way of a person when opened on either side, and since the doors are in contact with the door frame on all four sides, the airtightness is high, and the heat insulating effect and the soundproofing effect are excellent. On the other hand, however, when the same space as the hinged door is provided because a storage portion for the sliding door is required, only half of the hinged door can be opened, and there is a problem that a frontage wider than the hinged door is required for mounting. Furthermore, since the door frame must be installed in the storage part, the cost becomes high, and the door and the frame rub against each other to move, so the durability is not always sufficient.
Airtightness is easily lost after many years of use.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems in the conventional door structure of a building, which is basically a hinged door or a sliding door.
A door housed in an opening having a horizontal frame can be opened by moving it along the opening surface or at a right angle to the opening surface, and by incorporating a mechanism that provides an intermediate movement between a sliding door and a hinged door, Another object of the present invention is to provide a door structure that can be mounted in a narrow space and has excellent airtightness and watertightness similar to a sliding door.

[0005]

The door structure of the present invention for achieving the above object is to move a door housed in an opening having a lateral frame along an opening surface or at a right angle to the opening surface. A door device that is opened by means of the above, and a mechanism for moving the door along the horizontal frame and a mechanism for rotating the door with respect to the horizontal frame are provided between the horizontal frames of the door. A metal piece is interposed, and the door moves along the horizontal frame, and at the same time, it rotates with respect to the horizontal frame, and the side end of the door moves from one side surface of the opening along the arc and the other side surface When it reaches, the door is formed to form an angle with the horizontal frame to be opened, which is a basic feature of the configuration of the present invention, and the hardware is provided between the upper frame of the door and the door. This is the second feature of the present invention. Furthermore, a third feature of the present invention is that the hardware includes a door-side carriage arranged in the door, a frame-side carriage arranged in the horizontal frame, and a connecting shaft for connecting these carriages, The side carriage and the frame side carriage are provided with gears that mesh with rack gears laid inside the door and inside the horizontal frame, respectively, in order to move the door along the horizontal frame, and the connecting shaft is erected on the door side carriage. A gear mechanism that engages with a rack gear laid on the side surface of the horizontal frame and rotates horizontally at the upper end of the connecting shaft that protrudes above the frame-side carriage. The rotation of the door with respect to the horizontal frame is performed by rotating the door-side carriage with respect to the horizontal frame via the connecting shaft by meshing of the gear and a rack gear laid on the side surface of the horizontal frame. Especially.

The door structure of the present invention, as shown in FIGS. 1 and 2, has the door 1 housed in a door frame having a horizontal frame 3 and preferably also a vertical frame 4 in the X ₁ direction along the door frame surface or the door. It is opened by moving in the X ₂ direction perpendicular to the frame surface, and is provided with a mechanism for moving the door 1 along the horizontal frame 3 and a mechanism for rotating the door 1 with respect to the horizontal frame 3. The metal fitting 2 is provided between the horizontal frame 3 and the door 1. The horizontal frame 3 is generally only an upper frame, but in some cases comprises an upper frame and a lower frame, and the hardware 2 is preferably provided between the upper frame and the door, It may be interposed between the door and the door, and may be provided both between the upper frame and the door and between the lower frame and the door.
All the hardware is stored inside the frame and door. Further, the vertical frame 4 may be omitted, and as the frame material, only a horizontal frame composed of an upper frame and / or a lower frame may be installed to form an opening portion in which the door is housed.

2 to 3, for example, when the door 1 is pulled in the X ₁ direction, the door 1 moves along the upper frame 5, and the hardware 2 also moves in the upper frame and the door in the same direction. The hardware 2 is composed of a frame-side carriage 3, a door-side carriage 4, and a connecting shaft 5 that connects the carriages. The connecting shaft 5 standing upright from the door-side carriage 4 is a frame-side carriage 3
The rotation of the connecting shaft 5 is transmitted to the door-side carriage 4 to rotate the door-side carriage 4 about the through-hole of the frame-side carriage 3. The connecting shaft 5 of the metal piece 2 rotates as the metal piece 2 moves, and as shown in FIG. 3, the door 1 is rotated together with the door-side carriage 4 as indicated by an arrow Y.

In this case, as shown in FIG. 5, the side end portion 11 of the door 1 moves from the position of the vertical frame 9 along an arc C having the virtual center point O as an axis. As shown in FIG. 4 and FIG.
When one end 11 of the door 1 rotates as shown by the arrow Z to reach the position of the other vertical frame 10, the door 1 forms an angle α with the upper frame 8 and is opened. When closing the door 1, for example, when the one end 11 of the door 1 is pulled toward the vertical frame 9, the door 1 is closed by following a trajectory opposite to the above. The opening angle α of the door and the locus at the time of opening the door can be changed by adjusting the rotating mechanism of the metal as shown in FIGS. 6 and 7. The optimum trajectory and opening angle can be selected according to other situations.

[0009]

According to the structure of the present invention, the door is held by the metal object and is opened and closed so as to rotate about the center point O of the arc, but by the action of the metal object moving simultaneously in the door and the frame,
It is possible to freely control the door from fully open to fully closed, and it can be made to move like a sliding door or a door. At first, it is possible to move it like a sliding door and to make it move like a sliding door as it approaches full opening. Further, the same high airtightness and watertightness as the sliding door is maintained, and the occupied area S ₂ is smaller than the occupied area S ₁ (FIG. 9) of the conventional hinged door without obstructing the course of people near the door.
The maximum opening can be obtained (Fig. 5).

Since it can be opened and closed by a shaft like a hinged door, there is no need for a storage part like a sliding door, there is no need to install an extra frame, and installation is possible even in a narrow frontage space. Since the main load is received at the center of the door, unlike the sliding door, no excessive load is applied between the door and the frame, and it is possible to reduce the distortion of the door, damage to metal parts, wear of airtight rubber, etc. it can.

[0011]

EXAMPLES Examples of the present invention will be described below. Example FIG. 8 shows details of a metal object provided between the door upper frame and the door in the present invention. The hardware 2 comprises a frame side carriage 3, a door side carriage 4, and a connecting shaft 5 that connects the carriages 3 and 4, the frame side carriage 3 is housed in the upper frame 8 of the door 1, and the door side carriage 4 is of the door 1. It is housed in the upper rail 12. The connecting shaft 5 is erected on the door-side carriage 4 and has a through hole 17 in the frame-side carriage 4.
To the upper portion of the frame-side carriage 4 and to the end of the gear 1
8 is attached. The gear 18 meshes with a rack gear 20 laid on a side surface inside the upper frame 8 via a gear 19.

A gear 13 that meshes with a rack gear 15 installed in the upper rail 12 of the door 1 is attached to the door-side carriage 4, and a gear 13 that meshes with a rack gear 16 installed in the upper frame 8 is attached to the frame-side carriage 3. A gear 14 is attached. 21
Is a roller that rolls in contact with the upper surface of the upper rail 12 of the door 1, and 22 is a roller that rolls in contact with the lower surface of the upper frame 8 of the door 1.

The door 1 is held by a metal piece 2. When the door 1 is moved rightward along the upper frame 8, the movement is transmitted to the gear 13 by the rack gear 15 and the door side carriage 4 is moved to the right. Accordingly, the frame side carriage 3 connected to the door side carriage 4 by the connecting shaft 5 also starts to move to the right by the gear 14 and the rack gear 16. The rack gear 2 is moved by the movement of the frame side carriage 3.
The gear 19 that meshes with 0 and the gear 18 that meshes with the gear 19 rotate, and this rotational force is transmitted to the door-side carriage 4 through the connecting shaft 5 and imparts a rightward rotational force to the door-side carriage 4 to move the door 1 Rotate to the right.

Therefore, the door 1 moves to the right along the upper frame 8 and, at the same time, turns to the right and is opened in the above-described trajectory. In this case, if the combination of the gear and the rack gear is adjusted so that the movement amount of the dolly becomes about half of the movement amount of the door, as shown in FIG. 1 and FIG. The door structure may be configured to operate.

[0015]

As described above, according to the present invention, an intermediate movement between a sliding door and a hinged door is given to the door, and the door structure takes advantage of both the sliding door and the hinged door. That is,
It has the same air-tightness and water-tightness as sliding doors, and can be installed in places with narrow frontage.As with hinged doors, no unreasonable load is applied between the door and the frame, and damage to the door and parts is reduced, and it is durable. Sex is obtained. As for opening and closing, smooth opening and closing that corresponds to the natural movements of humans is realized.

In the case of a front door for a store, the door structure of the present invention, which can be smoothly opened and closed from both sides and has airtightness, can be suitably used, and it is difficult to install a normal sliding door because the frontage is narrow in a general house. The door structure of the present invention, which has the same opening and closing sensation and function as a sliding door and has the same opening area as a hinged door, is optimal. Further, if the door structure of the present invention is applied to the door for persons with disabilities who need access to a wheelchair in a hospital or the like, the person does not have to move to open and close the door, and the door can be easily opened and closed while sitting on the wheelchair. can do.

For partition doors such as staircases and emergency doors, a large hinged door has been conventionally used because it is necessary to obtain a wide opening when the door is opened. However, since the hinged door can be opened only in one direction, it is extremely difficult. There will be restrictions on evacuation routes. In this case, according to the door structure of the present invention, it is possible to obtain the maximum opening in the minimum required space, it is possible to open and close from both directions, and since it is airtight, high safety is secured.
