Description

[Detailed Description of the Invention] The present invention relates to an improvement of a door device for a slide-type sash with a dismount, such as a sliding shoji or a single-sliding shoji.

Conventionally, in this type of door roller device, as shown in Fig. 6,
A rail p stands up on the lower frame of the opening, and a groove wheel r attached to the shoji frame q runs on the rail p to open and close the shoji in a stable state.

However, in this case, since the rail p stands up, dust and grit tend to accumulate inside the rail p, and this rail p gets in the way and is difficult to clean.Furthermore, when it rains, rainwater leaks inside the rail p. It is a cause of impeding the watertightness of the satsushi.

This proposal was proposed to eliminate such drawbacks, and includes a quick-forming piece 2 hanging vertically from the shoji frame mounting piece 1.
A shoji mounting casing A having inclined groove holes 3 bored in the front and rear pieces of the casing A, and a shoji mounting casing A that is slidably fitted only in the vertical direction to the quick-forming part 2 of the casing A, and the inclined slots 3 are formed in the front and rear walls of the shoji mounting casing A. A horizontal piece 7 is extended forward from the lower end of a vertical piece 6 formed by extending one side wall of a quick-forming piece 5 in which sloped grooves 4 facing opposite to the grooves 3 are respectively bored. At the same time, a retaining piece 8 is protruded from the horizontal piece 7 and is slidably in contact with the back of a retaining frame hanging from the lower frame of the opening having the door roller rolling slope a. A door roller casing C in the form of a gate frame, which is slidably fitted into the member B and the quick-forming member 5 of the slide member B, and in which the door roller 9 is pivoted in the center.
The front and rear ends of the pins 10 fitted on both sides of the door roller 9 of the door car casing C are connected to the casing A, respectively.
The present invention relates to a sliding door roller device of a sliding type sash, which is slidably fitted into each of the inclined groove holes 3 and 4 of a sliding member B.

In the figure, 11 is a mounting hole drilled in the shoji frame mounting piece 1 of the shoji mounting casing A, 12 is a through hole for mounting the axle 13 of the door roller 9, which is drilled in the center of the door roller casing C, and 14 is the door roller casing. C shows a mounting hole for the pin 10 drilled in C, and the retaining piece 8 may be configured of a rolling wheel that is mounted on the horizontal piece 7 and rolls along the retaining frame. Alternatively, it may be constructed of a slide piece made of synthetic resin or the like that slides on the opening frame.

When the shoji mounting casing A of the door roller device according to the present invention is attached to the shoji lower stile via the shoji frame attachment piece 1, and the shoji with the device of the present invention mounted thereon is hung from the lower frame of the opening, the door roller device of the present invention is installed. Since the external force applied to the door roller 9 becomes zero, the door roller housing C to which the door roller 9 is attached tries to slide down along the inclined groove hole 3 in the shoji mounting casing A via the pin 10 due to its own weight.

At the same time, the annular piece 5 of the slide member B is fitted into the annular piece 2 of the casing A so that it cannot slide in the horizontal direction but can freely slide in the vertical direction. The oblique slot 4 of the piece 5 presses down on the pin 10 of the door roller casing C.

Since the pin 10 is fixed to the door roller casing C, the door roller housing C and the door roller 9 pivoted thereon are lowered along the inclined groove hole 3 via the pin 10.

Meanwhile, the slide member B descends to the state shown in FIG. 4 using the pin 10 and the inclined slot 4 as guides.

In this state, as shown in Fig. 5, slide the shoji into the slide member B.
A vertical piece 6 formed by extending the rear wall of the annular piece 5 in
The retaining piece 8 on the horizontal piece 7 extending further forward from the lower end is located on the back side of the retaining frame, and the door roller 9
When set so as to rest on the door roller transfer slope a of the opening lower frame, the weight of the shoji is added to the door roller device of the present invention, and as a result, the door roller 9 and the door roller casing C are inserted into the inclined groove in the shoji mounting casing A via the pin 10. At the same time as the pin 10 moves upward using the hole 3 as a guide, the pin 10 presses the inclined groove hole 4 of the slide member B.

Since the annular piece 5 of the slide member B is configured to be able to slide only vertically on the annular piece 2 of the shoji mounting casing A and cannot be moved laterally, the slide member B is 10 and the inclined slot 4 as guides, the door roller 9, the door roller casing C on which it is mounted, and the slide member B rise to the position shown in FIG.

At this time, the door roller 9 and the door roller casing C on which it is mounted,
The amount of vertical movement with respect to the slide member B is proportional to the ratio of the slopes of the inclined slots 3 and 4.

However, in this case, since the inclined slot 4 is configured to have a steeper slope than the inclined slot 3, the door roller 9 and the door roller housing C
The amount of vertical movement of slide member B is larger than the amount of vertical movement of .

That is, the distance t between the door roller 9 and the retaining piece 8 when the door roller is raised as shown in FIG. 3 is smaller than the distance t2 between the door roller 9 and the retaining piece 8 when the door roller is lowered as shown in FIG. .

Therefore, according to the present invention, the interval t1. Taking advantage of the difference in t2, the door roller 9 of the present invention is constructed as shown in FIG.
is in contact with the door roller transfer inclined surface a in the lower frame of the opening, and the retaining piece 8 is set so as to slidably contact the back surface of the retaining frame suspended from the front end of the inclined surface a. It is.

When opening and closing the shoji to which the door roller device of the present invention is attached, the door roller 9 rolls along the door roller transfer slope a provided at the lower frame of the opening. Since the shoji slides into contact with the back surface of the retaining frame which is hung from the front end of the shoji, the shoji can run smoothly without coming off from the lower frame of the opening.

Further, according to the present invention, the door roller 9 does not ride on the rail raised from the lower frame of the opening as in the conventional case, but runs directly on the door roller transfer slope a of the lower frame of the opening, so it does not run on the rail as in the conventional case. There is no risk that dirt, sand, etc. may easily accumulate inside the rail, making cleaning difficult due to the rail getting in the way, and furthermore, even in the event of rain, rainwater flows down along the slope a. The present invention has many advantages, such as the fact that it does not stay inside the rail and impede the watertightness of the sash, unlike in the past.
