Description

[Detailed explanation of the idea] [Purpose of invention] "Industrial application field" This invention relates to a shoji sliding device.

``Prior art'' A vertically movable member, for example, a slide bar, is used to freely move up and down in the connecting frame, and pulling tools are provided above and below the member, and the pulling tools are engaged with the upper and lower rails of the upper frame and the lower frame. The shoji screen is drawn to the opening frame. Such a pulling device is provided for double sliding shoji and single sliding shoji. Generally, after installing the shoji on a sash and completing the glass construction, the installation of the shoji is adjusted by moving the door roller up and down.
If a problem arises in the engagement distance between the pulling tool and the upper and lower rails due to the amount of adjustment, the movement of the pulling tool in and out is adjusted to an appropriate engagement distance. In order to adjust the amount and uniformity of the pulling amount of the shoji, it is necessary to determine the vertical position of the pulling tool, but if the shoji does not have an adjustment mechanism at all, check the pulling state of the shoji before adjusting the shoji. Adjustments are made by removing the puller, disassembling the puller, and cutting the puller parts.

In addition, such adjustment of the pulling amount causes relatively large wear when the pulling tool is a linear cam, and even when the pulling tool is a rotating cam, there is a risk of damage to the bearings, etc. from the operating handle to the pulling tool. The amount of attraction changes due to wear. Therefore, adjustment of the amount of attraction occurs during assembly and after long-term use. Therefore, a pulling device has been proposed that has a mechanism that easily adjusts the amount of pulling. An example of a pulling device that can adjust the amount of pulling will be described below.

Figure 3 is a vertical cross-sectional view of the upper part of the sliding shoji stile shown in the internal and external directions, and Figure 4 is B-- in Figure 3.
B sectional view, Fig. 5 is the C-C sectional view of Fig. 3, Fig. 6
The figure is a front view of the slide bar. In the figure 1
7 is the upper frame, and 1 is the stile for the inner shoji. A tightening handle device (not shown) is provided in the middle of the connecting frame 1 in the vertical direction.
It fits into the groove 26 so as to be vertically movable. The slide bar 2 is provided with an oblong hole 27 in the vertical direction, and a piece 28 having a tip having the same shape as the oblong hole 27 is fitted into the oblong hole 27. The piece 28 is provided with a hole at the center C1 near the top and bottom ends, into which a machine screw 29 is inserted.
A machine screw 29 is inserted into the hole and screwed into the pulling tool 11. The pulling tool 11 is guided into a groove adjacent to the wide T-groove 26 across the bottom member of the wide T-groove 26 into which the slide bar is fitted. Wide T
A long hole 31 is provided in the bottom member of the groove 26 to allow movement of the piece 28.

To adjust the position of the puller 11, use the machine screw 29.
Screw it back and insert the piece 28 into the oblong hole 2 of the slide bar 2.
7, turn it upside down, change its position relative to the pulling tool 11, and insert the piece 28 into the oblong hole 27.
Slide bar 2 via piece 28 with machine screw 29
and the pulling tool 11 are connected. By doing this, the pulling tool 1 is moved by the distance δ between the center C1 of the hole of the machine screw 29 and the vertically opposite position C2 of the symmetrical piece 28.
1 position is adjusted. The same applies to the pulling tool that engages with the lower frame.

Generally, devices with a mechanism for adjusting the position of the pulling tool are provided inside the stile and cannot be adjusted without disassembly, but the above-mentioned conventional example is suitable because it can be adjusted from the outside.

"Problems to be Solved by the Invention" In the conventional example described above, the adjustment amount δ is fixed and only a constant amount of adjustment can be obtained, so there are the following problems.

In the lower pulling part, when the shoji is adjusted upward by adjusting the door roller, the piece 28 is turned upside down and the pulling tool 11 is adjusted in the exit direction, but this adjustment amount is larger than the adjustment amount of the door roller. In this case, the tip of the pulling tool 11 hits the lower frame, and the reaction force controls the rotational force of the handle, causing damage to various parts if the operating handle is turned forcibly. Therefore, in order to make fine adjustments, it is necessary to prepare a large number of pieces with different adjustment amounts δ. However, it is not practical for management to prepare such pieces at the construction site where construction is to be carried out;
Since this is a durable product, it is impossible to prepare a variety of pieces in order to readjust the pulling amount as the period of use passes. A similar problem exists in the upper pulling section.

This invention solves the above-mentioned problems in the shoji pulling device, and provides a mechanism for adjusting the pulling device of the shoji pulling device in which the amount of adjustment of the pulling device is continuous and can be adjusted while the shoji is erected. The purpose is to provide
