Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a door structure that can lock a four-sided door equipped with an open-air lattice door by locking at one location.

(Prior Art) In rooms with large frontages, four-sided glass doors, windows, rain shutters, etc. are installed.

In hot seasons such as summer, an atrium lattice door is sometimes installed on these four-sided doors to improve ventilation and to prevent crime at night.

For example, the conventional structure has four glass doors 3A to 3D on the sill 2 between the pillars 1 and 1, as shown in Fig. 4.
is embedded.

Two surfaces, an outer left glass door 3A and an outer right glass door 3D, are fitted into the end side of the running part on the outdoor side of the sill 2, and an inner left glass door 3B and an inner right glass door are fitted into the center of the running part on the indoor side. Two sides of the glass door 3C are fitted, creating a four-sided sliding door structure.

Further, an open-air lattice door 4 is installed between the outside left glass door 3A and the outside right glass door 3D on the outdoor side.

In this case, the outer left glass door 3A and the outer right glass door 3D on the two outdoor sides that touch pillars 1 and 1 are usually not opened, but only the left glass door 3B and the inner right glass door 3C on the two indoor sides. It is opened and closed by moving it left and right.

During the day, inside left glass door 3B and inside right glass door 3
C is left open on both sides, but when sleeping at night, the inner right glass door 3C is closed and the key 5 is locked, and the inner left glass door 3B is left open so that wind can blow through the open-air lattice door 4.

However, when sleeping while letting in the wind through the open-air lattice door 4, the outer left glass door 3A and the open-air lattice door 4 are not locked and can be easily opened from the outside.

For this reason, it is possible to attach a wedge-shaped fixing device to the outside left glass door 3A and the open-air lattice door 4 to prevent it from moving, but since the open-air lattice door 4 can be removed from the outside, it is necessary to securely close the door. I couldn't do it.

(Problems to be solved by the invention) The present invention was devised in view of the above points.
Doors 3A, 3C, and 3D on three sides and the open-air lattice door 4 can be locked with one touch by locking at three locations, and the open-air lattice door can be securely closed without removing the open-air lattice door 4 from the outside, and the open-air lattice door is excellent in terms of security. It provides an attached four-sided door structure.

(Means for Solving the Problems) The present invention will be explained in detail with reference to FIGS. 1 to 3.

On the running part of the outdoor side of the sill 2 provided between the pillars 1 and 1, there is an outer left glass door 3A and an outer right glass door 3.
The two surfaces of D are fitted into the running section on the indoor side, and the two surfaces of the inner left glass door 3B and the inner right glass door 3C are fitted.

The open-air lattice door 4 is attached between the outer left glass door 3A and the outer right glass door 3D, which are fitted into the running portion of the sill 2 on the outdoor side.

As shown in FIG. 2, grooves 7a and 7b are formed in the left and right vertical frames 6a and 6b of the open-air lattice door 4 along the vertical direction.

Further, on the vertical stile 6b of the outer left glass door 3A on the side of the open-air lattice door 4, there is a convex portion 8 that fits into the groove 7a.
are provided in the vertical direction.

Further, on the outer surface of the vertical stile 6a at the end of the inner right glass door 3C on the side of the open-air lattice door 4, an L-shaped protrusion 9 is provided to protrude toward the outdoors along the vertical direction.

(Function) In the above structure, during the daytime, as shown in Fig. 2, the inner left glass door 3B and the inner right glass door 3C are opened left and right, and the outer left glass door 3A and the outer right glass door 3D are overlapped and opened widely. I'll keep it. At this time, the glass doors 3A to 3D and the open lattice door 4 are not locked, so they can be opened and closed freely.

When sleeping at night, as shown in FIGS. 1 and 3, move the open-air lattice door 4 toward the outside left glass door 3A, and fit this convex portion 8 into the groove 7a on one side of the open-air lattice door 4. Match.

After this, move the inner right glass door 3C on the indoor side toward the open-air lattice door 4 side, and fit the L-shaped protrusion 9 protruding from the vertical stile 6a into the other groove 7b of the open-air lattice door 4. Match.

Next, the inner right glass door 3C and the outer right glass door 3D.
When the door is locked with the key 5, the three sides of the outer left glass door 3A, the inner right glass door 3C, the outer right glass door 3D, and the open lattice door 4 are locked with one touch, and the door can be closed.

For this reason, when sleeping at night, the open lattice door 4 is fitted from both sides to the left and right outer glass doors 3A and the inner right glass door 3C, so it cannot be removed from the outdoors.
Further, since the outer left glass door 3A and the open-air lattice door 4 do not move, the doors can be securely closed.

In this case, since the inner left glass door 3B is free, the amount of air flowing in can be freely adjusted by changing the overlapping state with the open-air lattice door 4.

In the above embodiment, the convex portion 8, the grooves 7a, 7b, and the L-shaped protrusion 9 are installed long along the vertical direction of the vertical stile.
A structure in which it is attached at several locations is also acceptable.

Further, although the above embodiments have been described in the case where the present invention is applied to a glass door, the present invention can also be applied to a rain door or a window.

(Effect of the invention) As explained above, according to the four-sided structure with the open-air lattice door attached according to the present invention, the doors 3A, 3C, 3D on three sides and the open-air lattice door 4 can be locked in one place with one touch. Furthermore, the open-air lattice door 4 cannot be removed from the outside, so it is excellent in terms of security.
