Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sliding door installation adjustment device that adjusts the inclination of a sliding door installed in a window frame.

[Prior Art] Conventionally, this type of sliding door, as shown in FIGS. 4 and 5, has a sliding door 1 located on the outdoor side and a lower frame rail 2 formed on the indoor side. When the sliding door 4 is closed, the sliding door 4 other than the door roller 3 is fitted and moved on the same plane as the door 1.

That is, as shown in FIGS. 6 and 7, the sliding door 4 has an operating cam 6 pivotally connected to the lower end of the sliding door 4 via a pivot pin 5, and a door roller provided with the door roller 3 on the operating cam 6. By rotatably mounting the casing 7 and operating a moving operation handle (not shown), only the sliding door 4 is moved toward the outdoor side via the operating cam 6 and closed on the same plane as the sliding door 1. The structure is such that the sliding door 4 can be opened by moving it from the outdoor side to the indoor side by operating a moving operation handle or the like.

However, in the conventional sliding door structure described above, the sliding door 4 built into the window frame tilts to the left or right due to errors in assembly dimensions, and when closed, the window frame and the sliding door 4, and the sliding door 1 and the sliding door 4 There is a problem that airtightness and watertightness cannot be maintained due to gaps between the parts. Conventionally, in order to adjust the inclination of the sliding door 4, an adjustment shim is inserted between the assembly portion of the door roller 3, but this method has drawbacks such as the adjustment work being troublesome and requiring a large amount of man-hours.

[Means for Solving the Problems] The present invention was made to solve the above-mentioned conventional problems, and its purpose is to adjust the installation of sliding doors built into window frames. The purpose of the present invention is to provide a sliding door installation adjustment device that is characterized by being simple and easy to operate, and as a means to achieve this purpose, it is installed in a window frame. One end of an operating cam is pivotally connected to the lower end of the sliding door via a pivot pin, and a door roller casing having a door roller is pivotally attached to the other end of the operating cam, and the operating cam and the door roller casing at this pivotally attached portion are A mounting pin is formed of a pipe with a female thread carved inside, and is provided in the door roller casing so as to be movable up and down, and a male screw threaded into the female thread is provided in the door roller casing to allow vertical movement. It is characterized in that it is provided so as to be restrained and rotatable, and that a fixing screw that presses the male screw and restricts rotation of the male screw is screwed into the female screw.

[Example] Hereinafter, examples according to the present invention are shown in Figs. 1 to 3.
This will be explained in detail based on the figures.

Fig. 1 is a partially cutaway front view showing the door roller device for a sliding door according to the present invention, Fig. 2 is a top view of Fig. 1;
FIG. 3 is a cross-sectional view of essential parts of the installation adjustment device shown in FIG. 1, and in the figure, parts that are the same as those in the conventional structure are given the same reference numerals and will be explained.

First, a pair of door rollers 3 are rotatably engaged on the lower frame rail 2, and the door roller casing 7, which rotatably includes the pair of door rollers 3, has its central portion connected to the operating cam 6 via the mounting pin 8. It is rotatably pivoted.

The mounting pin 8 attached to the center of the door roller casing 7 is incorporated into an installation adjustment device 10, as shown in FIG. 3a, so that the inclination of the sliding door 4 can be adjusted.

The installation adjustment device 10 includes a hollow mounting portion 11 formed in the center of the door roller casing 7, a bush 12 fitted within the mounting portion 11,
It consists of a mounting pin 8 that is movable up and down within the bush 12, a male thread 13 that moves the mounting pin 8 up and down, and a fixing screw 14 that maintains the relative position of the mounting pin 8 and the male thread 13. There is.

As shown in FIG. 3b, the mounting pin 8 consists of a mounting portion 8a to the operating cam 6 and a cylindrical body 8b that moves up and down within the bush 12.
A tool hole 8c is formed in the cylindrical body 8b.
A female thread 8d that is screwed into the male thread 13 is formed inside. Further, a female threaded portion 8e into which a fixing screw 14 is screwed is formed between the tool hole 8c of the mounting pin 8 and the female thread 8d, and the tip of the fixing screw 14 is pressed against the upper end of the male thread 13. There is.

Note that the lower end of the male screw 13 is connected to the flange portion 11a from the lower surface of the mounting portion 11 of the door roller casing 7.
It is fixed to a holding member 15 which is assembled by sandwiching the two parts, so that the two parts rotate together.

[Function] Therefore, when adjusting the inclination of the sliding door 4 using the built-in adjustment device 10 configured as described above, when the sliding door 4 is operated in the closing direction,
The door roller 3 and the sliding door 4 are separated, and the door roller 3 is exposed. Therefore, a hex wrench is inserted into the tool hole 8c of the mounting portion 8a located above the mounting pin 8, and the fixing screw 14 is loosened and removed, thereby allowing the mounting pin 8 to rotate freely.

Next, insert the screwdriver into the tool hole 8c,
Rotate the male screw 13. Rotate the screw 13. At this time, the male screw 13 and the holding member 15 are connected to the flange portion 11.
Since they are fixed together with a in between, they rotate only in that position. This rotation is transmitted to the mounting pin 8, and when this is moved upward or downward, the sliding door 4 moves up and down via the operating cam 6.

Note that two sets of the door roller casings 7 are installed on the left and right lower surfaces of the sliding door 4, so by moving the mounting pin 8 of either one up and down, the sliding door 4 can be prevented from tilting, and when the sliding door 4 is closed, the window frame The space between it and the shoji 1 will be sealed.

[Effects of the invention] As explained in detail above, the sliding door installation adjustment device according to the invention has a simple structure, and
Moreover, the inclination of the sliding door can be easily adjusted.

In other words, by rotating the male screw and moving the mounting pin up and down, the vertical height of the sliding door can be adjusted via the operating cam, making the adjustment operation simple and allowing for minute adjustments with high precision. can be highly adjusted.

In addition, since the mounting pin that pivotally supports the operating cam and the door roller casing is used as a height adjustment rod, there is no need for a separate pivot member, and the number of parts is small and assembly is easy. The adjustment male screw is incorporated into the mounting pin, making the entire device more compact.

Furthermore, since a fixing screw is provided that restricts the rotation of the male screw, the height after adjustment can be accurately maintained with a simple operation.

In addition, since the above-mentioned vertical movement adjustment device is generally installed at two places on the left and right sides of the sliding door, it can be easily adjusted between the window frame and the fitted door, and the airtightness of the sliding door. Watertightness can be further improved.

Furthermore, the above-mentioned installation adjustment device is fully applicable to sliding doors, and has the advantage of being versatile.
