Description

[Detailed Description of the Invention] The present invention relates to a door pull-down tool that pulls down a door that opens and closes vertically when closing the door.

Traditionally, when closing a door that opens and closes vertically, such as a shutter, you use an attached rod with a hooked hand at the end to hook the hooked hand into the hole at the bottom of the door, and pull the door down to a certain extent. It was closed by hand. However, when I did that, I used some skill to insert the hook of the attached stick into the hole at the bottom of the door. Also, it was a pain to have to search for the attached stick each time I wanted to close the door, and to clean up the attached stick after closing the door.

The present proposal was devised to eliminate these drawbacks, and will be explained with reference to the drawings as follows: (a) A flexible string 1 made of synthetic fiber, metal, hemp, etc. is provided at one end with an attachment part 2 for the door.

(b) A fixing part 3 is provided at the other end of the string 1 to be fixed to a wall, pillar, etc.

(c) A puller 4 with a pulley or the like inside is provided so that the string 1 can be moved freely.

(d) Attach the puller 4 near the attachment point 2 of the string 1 to the door.
However, a pull stopper 5 is provided so that the side of the attachment part 2 to the door does not go all the way.

Since the proposed structure is as described above, when using this, attach the attachment part 2 to the door to the lower end 7 of the door, and attach the fixing part 3 to a place 8 near the door 6 where it will not move as much as possible. Then, when the door 6 is fully closed to the bottom, the string 1 is made to loosen a little.

When closing the door 6, pull the handle 4 down.
Once door 6 has been lowered to the point where you can reach it, use your hands to lower door 6 as far as it will go and close it. At this time, the puller 4 does not touch the ground due to the puller stopper 5.

When opening door 6, you can open it in the usual way,
You may hold the string 1 in your hand and pull it upward, and once it opens to a certain extent, you may pull up the lower end 7 of the door 6 with your hand to open it.

Also, if the door 6 moves slowly or if the pull handle 4 is in the way, remove the pull handle 4. In that case, when closing the door 6, lower the string 1 on the side where it attaches to the door 2 from the bent part 9 where the string 1 bends and hangs vertically until the door 6 is within reach. All you have to do is draw it.

If the door 6 is large and has a particularly heavy movement, the string 1 may be made of something that can withstand large forces, such as a chain or net.

If there is a pillar 10 near the door 6, move the fixed part 3 to the pillar 1.
It may be set to 0. In this case, the fixed part 3 is
If you attach it below the bottom edge 7 when fully opened,
The string 1 can be short. Furthermore, since the string 1 does not hang down much, it does not get in the way.

If the string 1 is made elastic by using a rubber string or the like, when pulling down the door 6, all you have to do is hold the bent part 9 and pull it down. Further, the fixing part 3 may have a built-in elastic device, or the fixing part 3 itself may have elasticity. In this case, if a pull tab 4 is attached to the bent portion 9, the door 6 can be pulled down even more easily. If the movement of the door 6 is heavy, if possible, reduce the elasticity of the string 1.
If the movement of the door 6 is light, elasticity may be imparted to either the entire string 1 or to the fixed part 3 side from the bent part 9.

If several doors 6 are connected horizontally, they can be used more effectively by fixing a pole such as bamboo to the bent part 9 of the present invention and lowering advertisements, awnings, etc.

As described above, the present invention has a simple structure and the door 6 can be opened and closed quickly and easily.
