Therefore, manufacturing cost and inventory management cost can be reduced.
In addition, a recess for holding the long horizontal frame side connecting member formed in the long horizontal frame and a recess for holding the short horizontal frame side connecting member formed in the short horizontal frame are formed only at the required positions. Therefore, the processing cost of the long horizontal frame and the short horizontal frame can be reduced.
In addition, since the recesses formed in the long horizontal frame and the recesses formed in the short horizontal frame are round holes, efficient processing can be performed using an end mill for the tool. Processing costs can be further reduced.
Furthermore, even after the long horizontal frame and the short horizontal frame are connected by the connecting tool, the long horizontal frame side connecting member is rotated back to the position where the connection is started, and the tip of the latching piece bulges from the opening. By extracting the portion, the long horizontal frame side connecting member and the short horizontal frame side connecting member can be easily separated.
Therefore, even if the left-opening horizontal frame or the right-opening horizontal frame is mistakenly formed at the construction site, the long horizontal frame side connecting member and the short horizontal frame side connecting member are separated and installed. A correct left-opening horizontal frame or right-opening horizontal frame that should have been formed on site can be easily formed.

As shown in FIG. 11 (b), it gradually comes close to the radially inner surface of the peripheral wall 4 and comes into contact with the radially inner surface of the peripheral wall 4.
Accordingly, as shown in FIG. 11A, the recess 14L (14R) of the long horizontal frame 12 is displaced by d1 in the direction away from the short horizontal frame 13, and the recess 15 of the short horizontal frame 13 is moved from the long horizontal frame 12. Even when the position d2 is displaced in the direction of separation, if the total displacement d1 + d2 is about 1 mm, the lateral frame side coupling member 2 and the short lateral frame side coupling member 3 can be strengthened while absorbing such positional deviation. Can be linked.
Even when there is a positional shift in the direction approaching the depth direction (front-rear direction), the positional shift can be absorbed in the same manner as in FIG.

The principal part enlarged plan view of FIG. 12A and the principal part enlarged partial longitudinal plan view of FIG. 12B show examples in the case where there is a positional shift in the left-right direction.
When the rotation operation piece 8 is operated to rotate the long horizontal frame side connecting member 2 around the cylindrical axis (rotation center axis) A as indicated by an arrow B in FIG. 12A, the rotation operation piece 8 in FIG. In this way, the intermediate portion of the latching protrusion piece 7 enters the latching groove 6 from the opening 5 and moves relatively away from the opening 5.
Accordingly, the peripheral bulge 4 where the tip bulging portion 7A of the latching protrusion piece 7 located on the inner side of the peripheral wall 4 of the lateral frame side connecting member 2 moves relatively away from the opening 5 and the thickness gradually increases. As shown in FIG. 12 (b), it gradually comes close to the radially inner surface of the peripheral wall 4 and comes into contact with the radially inner surface of the peripheral wall 4.
Therefore, even when the recess 14L (14R) of the long horizontal frame 12 and the recess 15 of the short horizontal frame 13 are relatively displaced in the left-right direction as shown in FIG. 12A, d3 is about 1 mm. Then, the horizontal frame side connecting member 2 and the short horizontal frame side connecting member 3 can be firmly connected while absorbing such positional deviation.
In addition, even when there is a positional shift in the left-right direction opposite to the relative positional shift in FIG. 12, the positional shift can be absorbed similarly to FIG.

According to the structure of the connecting tool 1 (the long horizontal frame side connecting member 2 and the short horizontal frame side connecting member 3) of the two-part horizontal frame 11 (the long horizontal frame 12 and the short horizontal frame 13) as described above, In the state where the short horizontal frame side connecting member 3 is attached to the short horizontal frame 13 in advance, the long horizontal frame 12 and the long horizontal frame side connecting member 2 are sent together with the long horizontal frame 12 to the construction site. In a state where the long horizontal frame side connecting member 2 is fitted to the place 14L or 14R, the tip bulging portion of the latching protrusion piece 7 of the short horizontal frame side connecting member 3 is inserted into the opening 5 of the long horizontal frame side connecting member 2. 7A is inserted, and when the long horizontal frame side connecting member 2 is rotated around the cylindrical axis A, the tip bulging portion 7A of the latching projection piece 7 whose middle portion enters the latching groove 6 from the opening 5 is latched. As a result, the connection is completed.
Therefore, since the connection can be completed by a one-touch operation of rotating the long horizontal frame side connecting member 2 around the cylindrical axis A, it is possible to reduce the work cost at the construction site and reduce the work cost.
Further, the long horizontal frame 12 has recesses 14L and 14R for holding the long horizontal frame side connecting member 2, and the short horizontal frame 13 has a recess 15 for holding the short horizontal frame side connecting member 3 only at necessary places. Since it should just form, the processing cost of the long horizontal frame 12 and the short horizontal frame 12 connected with the connector 1 can be reduced.
Furthermore, since the long horizontal frame side connecting member 2 is cylindrical, the recesses 14L and 14R formed in the long horizontal frame 12 can be formed into round holes so that the tool can be efficiently processed using an end mill. The processing cost of the frame 12 can be further reduced.

Furthermore, since the thickness of the portion of the peripheral wall 4 of the long horizontal frame side connecting member 2 that forms the retaining groove 6 is formed so as to gradually increase from the opening 5 in the circumferential direction, With the operation of rotating the frame side connecting member 2 around the cylindrical axis A, the tip bulging portion 7A of the latching protrusion 7 approaches the radially inner surface of the peripheral wall 4 where the wall thickness gradually increases, and the radial direction Since it is in a state of being brought into contact with the inner surface and being hooked, an operation for completing the connection is easy and reliable.
Further, a recess 14L or 14R for holding the long horizontal frame side connecting member 2 formed in the long horizontal frame 12, and a recess 15 for holding the short horizontal frame side connecting member 3 formed in the short horizontal frame 13. Therefore, it is not necessary to improve the position accuracy of the portion where the recess is formed with respect to the horizontal frame. Therefore, the two-part horizontal frame 11 for the sliding door using the connector 1 (the long horizontal frame 12 and the short horizontal frame 12) is used. The processing cost of the horizontal frame 13) can be further reduced.

Further, the long horizontal frame side connecting member 2 is provided with a rotating operation piece 8 operated when rotating around the cylindrical axis A, and the long horizontal frame side connecting member 2 is operated by operating the rotating operation piece 8. Since the cutout portion 9 is provided so as to be separated so that the rotation operation piece 8 is separated after the connection is completed when the rotation is made around the cylindrical axis A, the rotation operation piece 8 is operated to operate the long horizontal frame side. By rotating the connecting member 2, the long horizontal frame 12 and the short horizontal frame 13 can be easily connected without using a tool such as a screwdriver or a hexagon wrench, so that the work cost at the construction site can be further reduced.
Furthermore, as the rotation operation piece 8 is operated, the notch 9 is broken after the connection is completed, and the rotation operation piece 8 is separated. Therefore, the long horizontal frame 12 and the short horizontal frame 13 are connected. Thus, after the two-part horizontal frame 11 for the sliding door is formed, the turning operation piece 8 does not get in the way.
The short horizontal frame side connecting member 3 is bonded in a state of being fitted into a round hole-shaped recess 15 formed in the short horizontal frame 13, and the short horizontal frame side connecting member 3 is bonded to the short horizontal frame. Since the projecting pieces 10, 10 that prevent rotation about the vertical axis with respect to 13 are provided in the short horizontal frame side connecting member 3, the short horizontal frame side connecting member 3 is a round hole-like recess formed in the short horizontal frame 13. Since the recess 15 formed in the short horizontal frame 13 has a round hole shape because it is fitted to the location 15, it can be efficiently processed using an end mill for the tool. Cost can be further reduced.
Further, since the short horizontal frame side connecting member 3 can be prevented from rotating around the vertical axis with respect to the short horizontal frame 13 by the projecting pieces 10, 10, the recess of the short horizontal frame 13 which is performed at a factory or the like before being sent to the construction site. 15, the short horizontal frame side connecting member 3 is positioned in the direction of rotation around the vertical axis with respect to the short horizontal frame 13 when performing the work of bonding with the short horizontal frame side connecting member 3 fitted to 15. Therefore, the work cost of the work does not increase.

  According to the configuration of the two-part horizontal frame 11 for single sliding doors (the long horizontal frame 12 and the short horizontal frame 13) as described above, when forming the two-part horizontal frame for left-opening single sliding doors, the long horizontal frame When the long horizontal frame side connecting member 2 is fitted in the left opening recess 14L, the short horizontal frame 13 may be connected. When forming the two-part horizontal frame for the right sliding single sliding door Can be connected to the short horizontal frame 13 in a state where the long horizontal frame side connecting member 2 is fitted in the right opening recess 14R of the long horizontal frame 12, so that it is necessary by the same two-part horizontal frame for single sliding doors. Therefore, it is not necessary to prepare two types of horizontal frames for left opening and right opening for the same product, so that manufacturing costs and inventory management costs can be reduced.
