Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pulling tool for a roll blind.

[Prior Art] Conventionally, as shown in FIG. 1, a pulling tool for a roll blind has been formed at the lower part of a cylinder 2 that is attached to the lower end of the roll blind 1 and has a substantially H-shaped cross section and serves as a weight bar. approximately W-shaped groove 3
In this case, a rectangular plate member 5 having a handle string 4 or the like attached to the substantially center thereof is fitted from the end of the substantially W-shaped groove 3.

[Problems to be Solved by the Invention] However, the attachment state of the plate-like body 5 to the cylinder body 2 is unstable, and the plate-like body 5 may fall out from the opening of the approximately W-shaped groove 3 when pulled down, or There are drawbacks such as the plate-like body 5 itself being damaged. Also the second
As shown in the figure, a holding tool 6 with a pull string attached to the lower part is fitted onto the cylinder body 2, and a set screw or the like is screwed into the flat plate part 7 of the cylinder body 2 from below (not shown). Although such a method is superior in terms of appearance and function, it is inferior in that it requires screws, which requires time and effort to install, and is expensive.

The present invention was made in view of these points, and
It is an object of the present invention to provide a pulling tool for a roll blind that is simple in structure and installation, and yet robust.

[Means for Solving the Problems] In order to solve the above problems and achieve the object of the invention, the roll blind puller according to the invention is characterized by having the following configuration. That is, a plate-shaped body with a handle string or the like attached to the approximately central part is inserted from the end into a substantially W-shaped groove 3 formed in the lower part of a cylindrical body 2 with a substantially H-shaped cross section attached to the lower end of the roll blind. In the pull tool for a roll blind that is fitted and inserted, the plate-like body 5 has a U-shaped groove 51 in the transverse direction at the center in the longitudinal direction, and both free edges of the U-shaped groove 51 are directed outward. The U-shaped groove and the inverted U-shaped protrusion are pressed into and fitted into the substantially W-shaped groove 3 at the lower part of the cylinder body 2, The lower end 54 of the U-shaped groove 51 is connected to the lower part 31 of the substantially W-shaped groove 3.
, the upper ends 55, 55 of the inverted U-shaped protrusions 52, 52.
It is characterized in that it is brought into contact with the upper surface 32 of the approximately W-shaped groove 3.

[Example] The present invention will be explained in detail below using an example shown in the drawings. Note that the same components as those in the conventional example will be described with the same reference numerals.

3 to 5 show an embodiment of the present invention, in which a plate-like body 5 is provided with a U-shaped groove 51 in the lateral direction in the central part of its longitudinal direction, and the U-shaped groove 5
Both free edges of the handle 1 are bent outward to provide continuous inverted U-shaped protrusions 52, 52, and a handle string 4 having a grip ball 41 attached to the lower end is attached to the approximately central portion. A locking hole 53 is bored for the purpose. In addition, in this embodiment, the handle string 4 is connected to the plate-like body 5.
Although the structure is such that a hook or the like can be hung in place of the anchoring hole 53, a hook or the like may be installed in place of the anchoring hole 53 (not shown). And the plate-shaped body 5 attached to the handle string 4
In order to attach the plate-shaped body 5 to the cylinder body 2 attached to the lower end of the roll blind 1, insert the plate-shaped body 5 into the approximately W-shaped groove 3 formed at the bottom of the cylinder body 2 from either the left or right end. good. At this time, the lower end 54 of the U-shaped groove 51 provided in the center of the plate-shaped body 5 is connected to the lower part 31 of the substantially W-shaped groove 3, and the upper end 5 of the inverted U-shaped protrusions 52, 52
5 and 55 are pressed into contact with the upper surface 32 of the substantially W-shaped groove 3 and inserted. Therefore, the plate-like body 5 is elastically supported between the lower part 31 and the upper surface 32 of the substantially W-shaped groove 3.

[Effects of the invention] Since the present invention has the above-mentioned structure, it is simple in structure, suitable for mass production, and low in price. Since it is formed in the transverse direction, it is easy to insert into the cylinder and the support is reliable.
Since the plate-like body itself has a robust structure, it has various effects such as not being damaged even if excessive force is applied.
