A spring means 23 is provided to constantly press and bias the spring 21 toward the upper plate of the case 14, and one end thereof is aligned with one end of the guide elongated hole 14a, 14b of the case on both sides of the pin hole 21a of the side plate of the slide plate. A cam groove 24 whose other end is approximately the same width as the guide elongated hole that slopes upward.
a and 24b are provided.

FIG. 4 is a perspective view of each member of the pulling device shown in FIG. 3.

Next, the operation of this pulling device will be explained.

When the handle 4 of the handle device 11 is in the original position, the connecting pins 13a and 1 of the bar material 12
3b is fitted and engaged in common with the starting ends of the guide slots 14a and 14b of the case 14 and the starting ends of the cam grooves 24a and 24b of the slide plate 21, and the pin shaft 18
is inserted into contact with the lower end of the elongated hole 21a of the slide plate 21 and into the pin hole 18a of the case, and the lower surface of the lower plate 16a of the hook plate 16 is flush with the upper plate of the case. (Position of solid line in Figure 3a).

Next, when the handle 4 is rotated to move the bar material 12, the connecting pins 13a and 13b also move in the direction of arrow a along the guide elongated holes 14a and 14b, and this movement of the connecting pin makes contact with the connecting pin. The connecting pin 1 acts to push down the slide plate 21 until the lower surfaces of the cam grooves 24a and 24b of the slide plate that are attached to the slide plate reach the lower surfaces of the guide slots 14a and 14b.
When 3a and 13b reach the end of the guide elongated hole, the slide plate 21 is lowered by the height (H) between the start and end of the cam groove. At this time, the slide plate 21 descends against the elasticity of the spring means 23, and since the length of the elongated hole 21a is made to match the height H of the cam groove, the pin shaft 18 is placed at the upper end of the elongated hole 21a. The hook plate 16, which has descended until it touches the slide plate and is therefore fixed to the slide plate, is connected to the notch hole 20.
The lower surface of the hook plate upper plate 16b presses against the door or shoji surface, and is pulled in until the lower surface of the upper plate 16b comes into contact with the bottom 20a of the notch hole.

To release the pull, return the handle 4 of the handle device 11 to its original position to release the connecting pin 13.
a, 13b return to the starting ends of the guide elongated holes 14a, 14b and the cam grooves 24a, 24b, the pressure on the cam surface by the connecting pin is released, and the elasticity of the spring means 23 pushes the slide plate 21 upward by an amount H. The lower end of the shaft 18 comes into contact with the lower end of the elongated hole 21a and stops, so that the lower end of the hook plate lower plate 16a returns to its original state flush with the upper plate of the case 14, and the draw of the door is released.

The above-mentioned pulling device will operate more reliably if it is provided at two locations above and below the vertical stile 10 so as to perform the pulling operation simultaneously, as shown in FIG. 1a.

As described above, the present invention includes a case that is housed inside a matching vertical stile and has a cutout hole on the top surface, and a case that is provided in a groove on the surface of the vertical stile on the back of the case and spaced apart.
A bar material to which one end of a connecting pin of a book is fixed, a handle device for moving the bar material in the longitudinal direction along the groove, and a hook plate that is housed inside the case and fits into the notch hole of the case. A slide plate fixed to the top surface, a pin shaft that aligns the center line of the pin hole provided on the side of the case with the upper and lower elongated holes provided on the side of the slide plate, and inserts the pin shaft into both holes in common. A spring means that is wrapped around the pin shaft and constantly presses the slide plate toward the upper plate of the case, a horizontal guide hole provided on the side surface of the case on each side of the pin shaft, and a horizontal guide hole provided on the side surface of the slide plate. A cam groove whose starting end coincides with the guide elongated hole and whose terminal end is inclined upward, and two connecting pins that are fixed to the bar material and are inserted through the guide elongated hole and the cam groove in common. When the connecting pin moves due to the movement of the door, the hook plate is lowered within a certain range within the notch hole of the case against the spring means, and the door is pressed by the hook plate to exert a pulling action. Therefore, the door and the stile can be automatically pulled together and released by operating the handle, and at this time, the spring means that constantly presses and biases the slide plate toward the upper plate of the case causes the door to be pulled by a reaction force. It has the feature of ensuring the pulling state and working effectively as a return device when the pulling is released.
