[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a connection mechanism between a weight bar of a roll blind with side rails and a runner in the side rails.

[0002]

BACKGROUND OF THE INVENTION-out with side rails Russia Lumpur blind,
To raise and lower the weight bar with the screen lower end fixed along the side rail, a runner is arranged in the side rail, and the runner and the weight bar are connected via a pin. Conventionally, a pin has been fixed to a runner and inserted freely into and out of a pin hole at an end of a weight bar.

[0003]

[Problems to be Solved by the Invention] If the pin connecting the runner and the weight bar is short, the weight bar may be detached from the pin. Therefore, it is desirable to increase the length of the pin. Since the length of the pins is about the same as the left and right side rails, the longer the pins, the greater the angle at which the weight bars, that is, the pins, are inclined with respect to the screen surface when inserting the pins into the weight bar. There is a problem that there is a risk of damaging the device.

[0004] The present invention has been made to solve this problem, and it is an object of the present invention to provide a weight bar that allows a pin fixed to a runner to be inserted into the end of a bar without obliquely setting the pin. is there.

[0005]

In order to achieve the above-mentioned object, the present invention adopts a means in which a joint chamber is formed at a lower portion of a weight bar and has an opening at an end face and a bottom face, and a pin hole is provided in the joint chamber. The joint is slidably disposed in the longitudinal direction, and the weight bar is provided with means for positioning the joint.

[0006]

The pin fixed to the runner protrudes long from the opening of the side rail, but when the joint positioning means of the weight bar is removed and the joint is shifted longitudinally inward from the end of the weight bar, the pin moves from the bottom to the joint chamber enter. Then, when the joint is returned to the original position, the pin enters the pin hole of the joint. Then, when the joint positioning means is attached and the joint is fixed, the weight bar and the runner are connected via the pin. The weight bar moves up and down integrally with the runner, but is mutually movable in the longitudinal direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The weight bar of the present invention will be described based on an embodiment shown in the drawings. As shown in FIGS. 1 to 3, the inside of the side rail 10 is divided into an inner screen insertion portion 13 and an outer runner running portion 14, and both edges 21 of the screen 20 enter the screen insertion portion 13. A runner 15 fits in the traveling unit 14 so as to be able to move up and down. The partition wall 24 inside the weight bar 23 divides the upper half into a screen mounting chamber 25 and the lower half into a joint chamber 26. The fastening plate 17 is wound around the lower end of the screen 20, and the fastening plate is inserted into the screen mounting chamber of the weight bar 23 so that the lower end of the screen 20 is
Attach to Joint chamber 26 has an opening from the end face to the bottom face
27, and the joint 30 is inserted into the joint chamber slidably in the longitudinal direction. Cap on end face of weight bar 23
28 is attached via a screw 29 to prevent the joint 30 from coming out of the weight bar 23. The rubber cover 31 is fitted into the opening 27 on the bottom surface of the weight bar 23. The end surface of the cover 31 abuts against the end surface hanging portion 32 of the joint 30 from inside.
Thus, the joint by the cap 28 and the cover 31
Fix the position of 30 but joint as shown by the dashed line
A bolt 33 may be screwed into the inner end of 30, and the tip of the bolt may be pressed against the partition 24 of the weight bar 23 to fix the joint 30. Runner 15 in pin hole 36 of joint 30
The pin 16 fixed to the connector is loosely fitted. A play is provided between the left and right side rails 10 and the weight bar 23 to cope with the winding deviation of the screen 20. Next, the connection between the weight bar 23 and the runner 15 of the present invention will be described.

As shown in FIG. 4, when the cover 31 is partially removed from the end of the weight bar 23, for example, by about 10 cm,
The joint 30 can be moved inward. Therefore,
The joint 30 is shifted inward from the projecting length of the pin 16, and the pin 16 is
Put into joint room 26 from 27. Then, as shown by the arrow B, the joint 30 is moved again to the end face to remove the pin hole.
When the pin 16 is passed through 36 and the cover 31 is refitted as shown by the arrow C, the runner 15 and the weight bar 23 are connected via the pin 16. During this connection, weight bar 23 and pin
Since there is no need to make the 16 beveled at all, there is no danger of the screen 20 being damaged by the connecting operation. Therefore, even if the weight bar 23 hits an obstacle, the pin 16
The insertion length of the pin 16 can be made sufficiently long so as not to come off.

[0009]

As described above, the weight bar of the present invention requires the weight bar and the pin to be inclined with respect to the screen when the pin fixed to the runner is passed through the pin hole of the weight bar. Unlike the thing, the weight bar and the pin do not need to be inclined with respect to the screen, so that there is no danger of damaging the screen during the connection work, and the insertion length of the weight bar of the pin can be made sufficiently long. It has an excellent effect that the runner of the bar is prevented from coming off.
