Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a rotating window, and more particularly to an airtight device thereof.

[Conventional technology]

For example, as an airtight device for this type of rotating window,
No. 59-85893 is known.

According to this proposal, the space between the opposing fins of the revolving door frame and the storage frame is sealed with a tiltable airtight material provided on the revolving door frame or storage frame side, and the airtight material is retractable. In conjunction with a closing device, the fin falls down when opened, and when closed, stands up and engages the opposing fin in a fitted manner, thereby sealing the space therebetween.

[Problem to be solved by the invention]

This proposal releases the contact state of the airtight material when opening the revolving window, so it reduces the frictional resistance seen in airtight devices in which the airtight material is placed in fixed sliding contact between the revolving door frame and the storage frame. This has the advantage of eliminating the weight of opening and closing the revolving door frame, but on the other hand, since the airtight material is made to be able to be raised and lowered, several rotating parts are required, making it difficult for dust to accumulate. This type of revolving door frame or storage frame is not necessarily of suitable structure, and there are still problems with durability such as poor tilting during long-term use and creaking noise when rotating. Also, since the airtight material fits into each opposing fin, a high degree of dimensional accuracy is required. It is also expected that this will cause sealing failure.

The present invention was made in view of such circumstances,
The problem to be solved is to provide an airtight device for a rotating window that maintains the above-mentioned advantage of eliminating the weight of opening and closing due to frictional resistance, while eliminating sealing defects caused by dimensional accuracy and having excellent durability. It is in.

[Means to solve the problem]

The present invention provides an airtight material whose outer protrusion width is variable by bending and restoring according to the relative position of the sliding door frame and the sliding member provided thereon. By sliding, when the revolving door frame is closed, the airtight material is brought into contact with the opposing part of the accommodation frame to seal the space between the revolving door frame and the accommodation frame, and when the revolving door frame is opened, the airtight material is brought into contact with the opposing part by restoring. In other words, the present invention is designed to release the seal by separating the slide from the revolving door frame. One end is held in the fixed side holding part of the rotating door frame, and the other end is held in the movable side holding part of the sliding member, and the outer peripheral side protrusion width is adjusted by bending and restoring according to the relative position of the sliding member. a sliding device that slides a sliding member in conjunction with a pulling device for a revolving door frame; and a contact portion of a housing frame that faces the airtight material at a maximum bending position of the airtight material; The present invention relates to an airtight device for a rotating window characterized by comprising the following, and this is the gist of the invention and is a means for solving the above-mentioned problems.

The present invention will be further explained with reference to the drawings showing embodiments. In the drawings, 1 is a vertical axis rotating window made of aluminum alloy, 2 is a rotating door frame of this rotating window 1, and 3, 4, and 5 are rotating door frames. The upper door frame, the lower door frame, and the left and right vertical door frames each have the same cross-sectional shape of 2, and 30 is the rotating window 1.
31, 32, and 33 indicate the upper frame, lower frame, and left and right vertical frames of the housing frame 30, respectively.

The airtight device is provided between the revolving door frame 2 and the accommodation frame 30, in this example, so as to cover the entire circumference thereof, and sealing between the revolving door frame 2 and the accommodation frame 30 ensures airtightness. In addition, by releasing the seal when opening the revolving door frame 2, the revolving door frame 2 can be easily opened and closed.

The airtight device includes a slide member 13 disposed so as to be slidable in and out directions by a slide guide 12 provided on the outer circumferential side of the revolving door frame 2, one end of which is held by a fixed side holding portion 8 of the revolving door frame 2, and a slide member 1
The airtight material 9 whose other end is held by the movable side holding portion 14 of No. 3, the slide device that slides the slide member 13, and the contact portion 3 of the housing frame 30 that opposes the airtight material 9.
4.

That is, on the outer periphery of the revolving door frame, that is, on the outer periphery of each of the upper door frame 3, lower door frame 4, and vertical door frame 5 in this example, fins 6 protruding from these door frames in the outer periphery direction are provided. A groove-shaped outward slide guide 12 is provided at an intermediate position of the fin 6 and is formed by protruding a guide fin orthogonal thereto toward the outdoor side.
The slide members 13 each have a fin shape facing toward the outer circumference, and at each door frame side position, L-shaped inward engaging protrusions 15 are provided perpendicularly thereto and protrude toward the indoor side. By fittingly engaging the engaging protrusion 15 with the slide guide 12, the slide member 13 can be slid inward and outward directions.

At the tip of the fin 6 and the tip of the slide member 13 in the rotating frame 2, in this example, a channel groove-shaped fixed side holding part 8 and a movable side holding part 14, which are opened in the outer circumferential direction, are located on the same line. As a result, the slide member 13
A movable side holding part 14 is provided whose relative position is variable so that the holding part 14 can be freely moved toward and away from the holding part 14 by sliding.

The airtight material 9 is made of silicone rubber and has a fitting base 10 having an arrowhead shape at both ends, and a curved thin connecting strip 11 that connects these fitting bases 10. The above-mentioned holding is carried out by fitting one fitting base 10 into the holding part 8 and the other fitting base 10 into the movable side holding part 14 of the slide member 13, respectively. In other words, the connecting strip 11 is bent in the outer circumferential direction by sliding the slide member 13 toward the indoor side, and restored to the above-mentioned curved shape by sliding toward the outdoor side. Accordingly, the outer circumferential protruding side of the airtight material 9 is made variable.

The contact portion 34 of the housing frame 30 with respect to this airtight material 9
is in contact with the airtight material 9 at the maximum bending position of the airtight material 9, that is, at the position of the airtight material 9 when the movable side holding part 14 of the slide member 13 is located closest to the fixed side holding part 8. In this example, the contact portion 34 is a fin-shaped member that protrudes toward the inner circumference at an intermediate position between the inside and outside of each of the upper frame 31, the lower frame 32, and the vertical frame 33. A bulging airtight part 35 is provided at the tip of the contact part 34 to promote the bending of the airtight material 9 and to obtain planar contact with the airtight material 9.
It is designed to have the following.

The slide member 13 is slid by interlocking the slide device with the pulling device of the revolving door frame 2, and simultaneously around the entire circumference of the revolving door frame 2.

The pulling device of this example is provided on each vertical frame 5 of the revolving door frame 2, and is latched to the vertical frame 33 of the storage frame 30 on the indoor side, thereby holding the revolving door frame 2 in a fixed position in the storage frame 30. The slide device uses a lever handle 26 that can be pulled together.
Slide member 1 rotates the lever handle 26.

The slide guide plate 18 held therein, a guide elongated hole 20 formed transparently in the base plate 19 of this slide guide plate 18, each elongated operating rod 21 having a pin 22 protruding from the outer circumferential side that engages with the guide elongate hole, and It is equipped with a rack pinion 27 that converts the rotation of the lever handle 26 into linear movement of the operating rod 21, and the operating rod 2
1 is provided in the upper door frame 3, lower door frame 4 and vertical door frame 5, respectively, and a corner block 2 is provided between these.
A plate spring-like connecting member disposed in a curved through hole (not shown) in the corner block 28 allows the vertical linear movement of the operating rod 21 of the vertical door frame 5 to be controlled by the upper door. The movement is transmitted to each operating rod 21 of the frame 3 and the lower door frame 4 so as to cause linear movement in the horizontal direction.

Therefore, according to the slide device of this example, by rotating the lever handle 26, each operating rod 21 moves linearly in each door frame, and the slide guiding plate 18 is actuated in the inward and outward directions via the pin 22. Then, the slide member 13 is caused to slide in the same direction inward and outward in conjunction with the lever handle 26, and as a result, the airtight material 9
The airtight material 9 is brought into contact with the contact portion 34 between the revolving door frame 2 and the accommodation frame 30 to seal the space, and the airtight material 9 is removed to release the sealing.

In addition, 25 in the figure is a screw 24 provided on the operating rod 21.
In addition to sealing with the airtight material 9, the escape hole 29 is an additional airtight material in the form of a single tongue provided on the outdoor side to reduce frictional resistance as much as possible.
