Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a totsuplanner mounting structure for a curtain opening/closing device used in, for example, a one-box type automobile.

2. Description of the Related Art For example, in the case of a one-box type automobile, there is a curtain opening/closing device that uses a drive device to open and close a curtain covering a side window glass.

In this type of curtain opening/closing device, a rack line linked to a drive device is inserted through a box-shaped guide rail arranged at the upper edge of the window glass opening, and the slide or roll is carried out along the guide rail. By attaching one of the movable runners for hanging curtains (hereinafter referred to as Totsu Planner) to the rack line, the curtains can be opened and closed automatically when the rack line is moved by the drive device. (This similar structure is shown in, for example, Japanese Utility Model Application Publications No. 11391/1983 and No. 5189/1989).

Problems to be solved by the invention Generally, long lines or guide rails are manufactured in advance and then cut to the specified dimensions during installation. If you uniformly attach a totsu planner to the rack line with such variations in dimensions, the curtains may not open completely if the rack line is short, or vice versa. It has been pointed out that there are cases where the door cannot be closed completely.

Therefore, the present invention provides a top planner mounting structure for a curtain opening/closing device that allows the curtain to be opened and closed reliably even if there is some variation in the dimensions of the guide rail or rack line.

Means for Solving the Problem A rack line that is moved by a drive device is inserted into a guide rail disposed at the upper edge of the window glass opening, and the curtain is slid along the guide rail. A plurality of runners are provided for hanging, and a protrusion for aligning the rack line along the longitudinal direction of the rack line is provided on the runner at the end of the curtain movement side, and the projection and the end of the rack line are aligned. It is attached by caulking with an introductory tube.

For example, if the rack line is a little short with respect to the guide rail, the rack line can be swaged by separating the protruding part of the runner at the end of the curtain movement side and the terminal part of the rack line by a specified distance and caulking it with a joint tube. substantially the entire length of.

Embodiment Hereinafter, an embodiment of this invention will be described in detail with reference to the drawings.

As shown in FIGS. 8 to 10, for example, a one-box type automobile 1 is provided with a curtain opening/closing device 5 for covering window glasses 2, 3 at the rear of a driver's seat with curtains 4, 4.

The curtain opening/closing device 5 is equipped with a drive device 9 consisting of a motor 7 and a gear unit 8 on a pillar portion 6 located between each of the window glasses 2 and 3, and a rack line 10 having a rack portion linked to the gear unit 8. is moved within a guide rail 11 with a box-shaped cross section disposed at the upper edge of the opening of the window glasses 2, 3, so as to correspond to each window glass 2, 3 attached to the end of the rack line 10. By moving the totsu planner 12, each curtain 4 can be opened and closed simultaneously by a free runner 13 which is slidably disposed on the guide rail 11 like the totsu planner 12.

In addition, each curtain 4 has its lower edge connected to the sub guide rail 1 below the opening of each window glass 2, 3.
1a and 11a via free runners 13.

Here, as shown in FIGS. 1 and 2, the totsu planner 12 has hooks 1 for hanging the curtain 4 on a runner main body 120 that slides along the guide rail 11.
21 is inserted, and the cap 122, which is loosely attached to the storage part 120a on the upper surface of the runner main body 120, is attached to the hook 121 while being biased by a spring 123, and the cap 122 is engaged with the recess 124a of the rack joint 124. It's becoming like that.

Note that the recess 124 of the rack joint 124
On both sides of a, guide portions 124 descend obliquely toward the side ends.
b is provided.

At the end of the rack joint 124 on the rack line 10 side, a protruding part 124d having an enlarged part 124c at the tip is provided.
24d and the end portion 10a of the rack line 10 are caulked and integrated by a cylindrical joint tube 14 shown in FIG. 6, and the rack joint 124 is fixed to the rack line 10.

According to the above embodiment structure, when installing the curtain opening/closing device 5 in an automobile, the driving device 9 is installed on the pillar portion 6 together with the guide rail 11,
Rack line 1 inserted into guide rail 11
The protruding part 124d of the rack joint 124 is aligned with the terminal part 10a of the rack line 10, and the protruding part 124d of the rack joint 124 is spaced at a predetermined distance so that the curtain 4 can cover the window glasses 2 and 3 justly. (see figure 7) or easy line 10
Further cut and shorten the rack joint 12.
4 (see FIG. 1) and crimped and fixed both with the joint tube 14.

In this case, the joint tube 14 includes the rack part 10b of the rack line 10 and the enlarged part 124c at the tip of the protruding part 124d of the rack joint 124.
It bites into the hole to ensure a secure connection.

In this way, by attaching the top planner 12 to each end portion 10a of the rack line 10 so that the overall length is the optimum length, the rack line 10 is reciprocated by the drive device 9 to ensure that each curtain 4 is connected to the window glass 2, 3 can be covered automatically.

In this embodiment, in case the drive device 9 breaks down or it is necessary to open and close each curtain 4 independently, the cap 122 is opened by pulling the hook 121 of the top planner 12 downward. Recess 124 in rack joint 124
When the runner body 120 is disengaged from the position a, the runner body 120 can be slid independently as shown by the chain line in FIG. 1, so that the curtain 4 can be opened and closed manually.

Note that when the runner body 120 is to be engaged with the rack joint 124 again, the runner body 120
When the cap 122 is moved toward the rack joint 124, the guide portion 124b of the rack joint 124 smoothly guides the cap 122 into the recess 124a.

In this way, substantially the entire length of the rack line 10 is extended to the protrusion 124d of the rack joint 124.
The adjustment is made by caulking the end portion 10a of the rack line 10 and the end portion 10a of the rack line 10, thereby dealing with variations in the dimensions of the rack line 10, etc.

Effects of the invention As explained above, this invention has a great practical effect in that even if there is some variation in the length of the rack line, etc., the curtains can be opened and closed as set.

Therefore, even if the dimensional accuracy of the rack line etc. is not very high, it can be adjusted by the joint tube, so there is no burden on accuracy control at the manufacturing stage.
