Description

[Detailed Description of the Invention] "Industrial Application Field" This invention relates to a sliding door for an opening in an inclined wall that is installed in an inclined wall of a building.

``Prior Art'' As seen in Japanese Utility Model Application Publication No. 62-36182, there is a sliding door for an inclined wall that is installed in an inclined wall of a building.

The structure of this sliding door will be briefly explained using FIG. An opening surface 2 is provided on the inclined wall W, and a window frame 3 is fitted around the four circumferences of this opening surface 2. The window frame 3 has an upper frame 3A, a lower frame 3B, and a vertical frame 3C like a normal window.
It is composed of The upper frame 3A and the lower frame 3B have longitudinal cross-sectional shapes deformed into a rhombic shape according to the inclination angle of the inclined wall W.

The upper frame 3A and the lower frame 3B have guides 4, 5, 6, 7 parallel to the slope of the inclined wall W, and the lower frame 3B
are provided with rails 8 and 9.

An inner shoji 11 and an outer shoji 12 are installed in the window frame 3. Vertical door wheels 13 and 14 are attached to the lower surfaces of the lower frames 11A and 12A of the inner shoji 11 and the outer shoji 12.

Also, lower stile 11A, 12A and upper stile 11B, 12
Horizontal door wheels 15 and 16 are attached to each side of B, and the vertical door wheels 13 and 14 and the horizontal door wheels 15 and 16 support the shoji 11 and 12 so that they can move freely while maintaining an obliquely inclined posture.

Airtight materials 17 and 18 are attached to each indoor side of the inner shoji 11 and the outer shoji 12, and these airtight materials 17 and 1
8 abuts against the inclined guides 4, 5, 6, and 7 to maintain airtightness and prevent rainwater, dust, etc. from entering.

"The problem that the idea is trying to solve" Previously, Yokoto car 15 and 16 had upper stile 11B and 12B.
Since the shaft is fixed to the upper and lower frames 11A, 12A, the upper frames 11B, 12B and the lower frames 11A,
The distance between the side surface of 12A and the guides 4, 5, 6, and 7 is constant. Since the structure is such that the airtight materials 17 and 18 are arranged between these fixed intervals, the airtight materials 1
The mounting heights of the guides 7 and 18 are set in advance so that they are in pressure contact with the guides 4, 5, 6, and 7 to some extent.

Therefore, when opening and closing the inner shoji 11 and the outer shoji 12, the airtight materials 17, 18 are moved by the guides 4, 5, 6,
7, and the wear is significant. Therefore, it has the disadvantage that it is difficult to maintain airtightness and watertightness over a long period of time.

The purpose of this invention is to provide a sliding door for an opening in an inclined wall in which the airtight material is hard to wear and the airtightness and watertightness do not deteriorate over a long period of time.

``Means for solving the problem'' In this invention, a swing function is added to the support shaft of the side door car, and a connecting means is provided that is linked to the locking handle, so that the side door car swings when locking and unlocking. The structure is such that the shoji can be moved laterally toward the outdoors and indoors by swinging.

Therefore, according to this invention, when the door is locked, the shoji can be pulled indoors by swinging the side door wheels away from the guide, and when the door is unlocked, the shoji can be pulled outside by swinging the side door wheels. It can be biased in the direction.

By being able to move the shoji indoors and outdoors in conjunction with the operation of the locking handle, the airtight material can be applied to the window frame or the shoji because the shoji is biased toward the outdoors when the window is opened. Sliding contact can be prevented.

Therefore, it is possible to prevent the airtight material from being worn out, and it is possible to maintain airtightness and watertightness over a long period of time.

"Embodiment" An embodiment of this invention is shown in FIGS. 1 to 4. In FIG. 1, parts corresponding to those in FIG. 5 are designated by the same reference numerals, and redundant explanation will be omitted. This example shows the case of a single sliding window. In other words, a case is shown in which the glass 21 is directly fitted into the window frame 3 in one half of the opening surface 2. Further, in this example, the glasses 21 and 22 are double glazed.

The rail 9 is attached to the lower frame 3B on the outdoor side of the fitted glass 21.
and inclined guides 4 and 6 are provided. A vertical door roller 14 provided on the lower surface of the lower stile 12A of the outer shoji 12 is engaged with the rail 9 to receive the load of the outer shoji 12, and a horizontal door roller 16 is engaged with the inclined guides 4 and 6 to move the outer shoji 12 in the lateral direction. The outer shoji 12 is supported so as to be openable and closable while maintaining an inclined posture under the load. Note that this example shows a case where the airtight material 18 is attached to the window frame side.

In this invention, the side door wheel 16 is supported so as to be swingable in a direction perpendicular to the opening surface 2. The support mechanism can be constructed as shown in FIG. 2, for example.

That is, the housing 24, which is bent into a U-shape as shown in FIG. 3, is attached to the upper and lower ends (the upper end side is shown in the figure) of the vertical stile 12C of the shoji 12 using the screw holes 24A.

There are holes 2 in the housing 24 which is bent into a U-shape.
4B is formed, and a converter 25 shown in FIG. 4 is rotatably supported by this hole 24B. In other words, the converter 25 has a hole 25A for attaching the shaft of the horizontal door wheel 16.
and a hole 2 for rotatably supporting the converter 25.
5B, and a roller 25 that engages with a cam 26 to be described later.
It has a hole 25C for pivotally supporting D (Fig. 2),
The hole 25B is matched with a hole 24B formed in the housing 24, and the converter 25 is rotatably supported in the housing 24 by passing a shaft 25F through the holes 25B and 24B.

A roller 25D is installed in the other hole 25C of the converter 25.
Fit the shaft 25E for mounting.

In this way, the side door wheels 16 are attached to the upper and lower ends of the vertical stile 12C. The mounting direction is selected such that the directions of the axes 25E and 25F match the transverse direction of the shoji 12. Therefore, the side door roller 16 is supported so as to be swingable in a direction perpendicular to the surface of the shoji 12.

A cam 26 is engaged with the roller 25D, and the cam 26
By moving up and down, the side door wheel 16 is operated to swing. In other words, the cam 26 has a convex surface 26A and a concave surface 26B as shown in FIG.
is in contact with the convex surface 26A, and the shaft of the side door wheel 16 is supported in a state parallel to the axis of the vertical stile 16C. Further, when the roller 25D comes into contact with the concave surface 26B of the cam 26, the side door wheel 16 swings and rotates counterclockwise from the state shown in FIG.

The cam 26 is operated by a locking handle 27 provided on the stile 12C. For this purpose, a pinion 28 that is rotated by a locking handle 27 is provided inside the vertical stile 12C, and two racks 29A and 29B are engaged with this pinion 28, and these two racks 29A and 29B are locked. By operating the handle 27, the cams 26 are moved in opposite directions, and the movement is transmitted to the upper and lower cams 26 (the lower cam is not shown) by the connecting member 31, so that the cams 26 are moved in opposite directions. move it to

Therefore, in the example shown in FIG. 2, when the locking handle 27 is rotated clockwise, the rack 29A moves upward.
The rack 29B moves downward, moving the upper cam 26 upward and the lower cam downward, and the roller 29B moves downward.
5D is dropped into the concave surface 26B.

As a result, the side door wheel 16 rotates counterclockwise, and the shoji 12 is pressed against the airtight material 18 provided on the window frame 3.

On the other hand, when the locking handle 27 is rotated counterclockwise, the rack 29A moves downward and the rack 29
B moves upward, moves the upper cam 26 downward and the lower cam upward, and brings the roller 25D into contact with the convex surface 26A.

As a result, the side door wheel 16 is rotated clockwise and comes into contact with the guides 4 and 6, and the reaction force thereof can bias the shoji 12 in a direction away from the airtight material 18.

"Effect of the invention" As explained above, according to this invention, in a shoji in which a load is always applied to the airtight material 18 side due to the inclined position, the cam 26 is moved in conjunction with the operation of the locking handle 27, and the cam The horizontal door roller 16 is swung in a direction perpendicular to the surface of the shoji 12 in accordance with the movement of the shoji 26, and the shoji 12 can be moved toward the indoor side and the outdoor side by the swing of the horizontal door roller 16.

In particular, when unlocking, the shoji 12 can be biased toward the outdoor side against the load generated by its own weight, and the shoji 12 can be separated from the airtight material 18, and the shoji 12 can be opened and closed in this state. Therefore, wear of the airtight material 18 can be reduced.

Therefore, the airtight performance and watertight performance can be maintained in the initial state for a long period of time.
