Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a window with an airtight mechanism that creates an airtight state between an opening frame provided around an opening in a building and a sliding door. .

(Prior Art) A conventional window with an airtight mechanism is known, for example, as described in Japanese Patent Application Publication No. 197592 of 1988.

In a sliding door, this air-tight window attempts to achieve sealing by filling and discharging fluid within a tube seal that is placed over the entire circumference of the gap between the opening frame and the fittings. However, since the fluid sealed in and discharged from the tube seal expands and contracts in a direction perpendicular to the direction of movement of the sliding door when it is opened and closed, the sliding door is pressed in a direction perpendicular to the direction of movement to create an airtight state.

Furthermore, Utility Model Application Publication No. 31157 of 1981 describes a structure in which a sliding door is pressed in a direction perpendicular to the moving direction and a frame member or the like is applied to a packing provided inside in advance to seal the door. There is.

(Problem to be Solved by the Invention) However, such conventional windows with an airtight mechanism have a structure in which the sliding door is pressed and sealed in a direction perpendicular to the direction of movement of the sliding door. has strong strength and is difficult to deform, but the strength of the window frame and opening frame as a whole is weak in the vertical direction and is easily deformed.

KII the tube seal in the direction where it is easy to deform like this.
Conventional structures in which sealing is performed by turning the door N or by moving and pressing the door itself have difficulty following deformation and maintaining airtightness.

Additionally, over a long period of time, the opening frame and the like are deformed by the force of the tube seal's expansion, causing the entire door to wobble when the airtightness is released.

In order to prevent these deformations, it is necessary to increase the strength of the window, which increases the thickness and weight of the window, resulting in higher costs and poorer operability.

(Means for Solving the Problems) The present invention has been made to solve the above-mentioned problems. A seal member is provided around the periphery that can protrude in the plane direction of the door in accordance with the opening and closing of the crescent handle, and in the inner vertical member, both sides of each sliding door protrude inwardly, and at least one inner vertical member is provided with a seal member that can protrude in the plane direction of the door in accordance with the opening and closing of the crescent handle. It is sealed using a sealing member.

(Function) According to the window with an airtight mechanism of the present invention, when the talent is closed, the sealing member protrudes only in the plane direction of the sliding door and is sealed with the opening frame.

Moreover, when releasing the seal, if the crescent is opened, the sealing member will be retracted.

( Example ) The present invention will be explained in detail below using examples.

1 and 2 show cross sections of the inner sliding door 1 and the outer sliding door 2 with the windows closed so as to make them airtight. At the periphery of each sliding door, an elastic seal member 7 made of a tube seal or the like having a slide member 8 fixed to the bottom thereof is disposed. This sealing member 7 is disposed so as to protrude in the portion where both sliding doors overlap, that is, the inner vertical member 5 and the bottom rail portion 6, in order to avoid the door roller.

Next, the airtightness W1B of each sliding door will be explained in detail.

First, the structure of the inner sliding door will be explained with reference to FIGS. 3 to 6.

A string 9 is arranged along the inner peripheral edge of the window frame of the sliding door and inside the seal part. One end of the string 9 is fixed to the shaft of the crescent 10, and the other end is fixed to the window frame via a spring 12. A roller 13 is provided at each bent portion of the string 9 so that the string 9 moves quickly. Since the string 9 is provided along the seal member 7, it is moved to the side so as not to overlap the rail 6 and the crescent 10 at the lower end rail portion and the vertical member portion of the crescent, and the string 9 is provided by the rollers 13. Changing the direction of the material.

Swing members 14 are attached to the string 9 at about three locations per side of the window frame. In the swinging Js material 14, a roller 16 is provided on the opposite side of the fixed part of the string 9 at the tip across the fulcrum 15 to smooth the movement with the sealing member 7.

On the other hand, the sealing member 7 is movable within the window frame 3 in the plane direction of the sliding door, and a spring provided between the window frame 3 and the sealing member 7 constantly acts on the swinging member 14 side. ing.

7 and 8 show the structure of the outer sliding door 2. The crescent receiving part 11 is formed to be movable along the elongated hole 17, and when the crescent handle 18 is inserted into the receiving part 11, the crescent receiving part 11 is movable along the elongated hole 17. The part 11 moves to the left in the figure, and the connected string 9
It has a structure that pulls.

The attachment of the string 9 and the structure of the sealing member 7 are the same as those for the inner sliding door 1, so a description thereof will be omitted.

Next, the operation of the actual example W1 will be explained.

Close the sliding doors 1 and 2 and press the handle 18 of the crescent 10.
Rotate and insert into the crescent receiving part 11. In the inner sliding door 1, a string 9 is wound around the shaft of the handle 18.

The entire string 9 is quickly and uniformly pulled by the rollers 13. The pulled string causes the IJ member 14 to stand up and try to push the bottom of the seal member 7 outward via the roller l6.

The extruded sealing member 7 is brought into contact with the protrusion s19 provided on the inner vertical member of the outer sliding door 2 on the inner vertical member 5, and is pressed against the opening frame 4 on the window frames on the other three sides. This will ensure that the entire circumference of the sliding door is completely sealed.

On the other hand, on the outside sliding door, the crescent handle l8
When the is rotated, the crescent receiving part 11 moves in the direction of movement of the door along the inclination of the tip of the handle, and the string 9 is pulled, raising the swinging member 14 and sealing as in the case of the inner sliding door. Push the member outward to press the seal member 7 against the window frame.

Next, a description will be given of when the sliding doors are opened.

When the handle 18 is rotated toward this side, the string 9 is loosened, and the sealing member 7 is pulled toward the frame together with the swinging member 14 by the spring force provided between the window frames 3, and the sealed state is released.

Generally, planar objects such as sliding doors and their frames have weak strength in the thickness direction, but are strong in the planar direction.

The sealing member 7 in the embodiment of the present invention performs sealing by suppressing the sealing member in the direction of the plane of the sliding door.

Therefore, according to the configuration of this embodiment, both the window frame 3 and the opening frame 4 are deformed, and airtightness is completely maintained.

Furthermore, as a result, both the window frame and the opening frame can be made to have lower strength than in the prior art, resulting in lower costs, as well as lighter weight and improved operability.

Furthermore, in the conventional technology, the deformation of the inner vertical member was the largest and it was difficult to achieve a complete seal, but according to this embodiment, the inner vertical member of the double sliding door protrudes inward, and at least one of the inner vertical members Since the seal member provided on the member is used to seal in the planar direction, it is possible to completely seal the inner vertical member portion as well.

(Effects of the Invention) As explained above, according to the window with an airtight mechanism of the present invention, since sealing is performed by expanding and contracting the sealing member in the plane direction of the sliding door, deformation of the window frame and opening frame is small. Complete sealing is possible.

Furthermore, it is not necessary to make the strength of window frames, opening frames, etc. as strong as in the prior art, and there is an effect that both cost and operability are improved.
