とがある。[Detailed explanation of the invention] Sliding sashes are generally widely used for residential sashes, but when children close the shoji, their fingers (hands)
There have been accidents involving. Although the performance of door rollers has improved and windows can now be opened and closed with very little force, the weight of shoji remains the same as before (in fact, some shoji have become heavier due to the trend toward higher-end shoji).
It is easy for adults to have inertia when opening and closing, so this is not a problem for adults, but for infants who are weak,
Accidents may occur because the door shoji cannot be stopped from moving.
本考案は引き障子を備える開口部における上述

い速度で閉まる。 In FIG. 1, when the inner shoji 6 or the outer shoji 7 is closed, the door stop 17 moves together with the inner shoji 6 and the outer shoji 7, and the elastic cap 23 hits the vertical frame 4 or the vertical frame 5. Since the movement of the piston 21 is stopped, the door stop main body 18 moves to the left in FIG.
The hydraulic oil in the cylinder chamber 19a on the front side of the piston 21 of No. 9 passes through the gap between the piston 21 and the cylinder 19, and enters the cylinder chamber 19b between the piston 21 and the packing 28, and the packing 28 resists the spring 29 to move the piston 21. (Figure 3). At this time, the energy of the motion of the inner shoji 6 or the outer shoji 7 is mainly consumed and converted into heat due to the throttling resistance passing through the gap between the piston 21 and the cylinder 19, and the inner shoji 6
Or the vertical frames 14 and 16 of the outer shoji 7 are vertical frames 4, 5 and 3.
The shock is absorbed and stops at about 5 cm. If you continue to apply force to the shoji by hand, the doorstop main body 18 will move to the left in FIG. and spring 2
The inner shoji 6 or the outer shoji 7 is closed at a slow speed by the force of the hand against the force 9.

まではないようになつている。 When the shoji is closed, the piston 2 is moved by the compression spring 29.
The oil on the front surface of piston 1 applies pressure to the front surface of piston 21 through the gap between piston 21 and cylinder 19, and tries to push piston 21 out. As already mentioned, although the compression spring 29 has the force to push out the piston 21 alone, it does not have the force to move the inner shoji 6 or the outer shoji 7.

代用するから簡易安価に製作できる。 As described above, this invention has a cylinder that is sealed on one side within the doorstop body attached to a sliding shoji and has a piston rod protruding outside from the doorstop body on the other side, and a sealing ring is provided between the cylinder and the piston rod. Either provide a spring to bias the sealing ring toward the piston, and provide a gap between the piston outer circumference and the cylinder so that the working fluid on both sides of the piston communicates with a throttle resistance, or seal the area between the piston outer circumference and the cylinder. The piston was equipped with an orifice, and a door stop with hydraulic oil filled in the cylinder chambers on both sides of the piston was attached to the shoji so that the end of the piston rod touched an opening frame such as a vertical frame, so the door stop was long and small. It fits within the width of the upper stile of the shoji and is easy to install. Even if you close the shoji at high speed, the speed will drop to a very low speed without any impact before the shoji closes. In that case, the distance between the vertical stile of the shoji and the vertical frame of the opening frame is 3 to 5 cm.
It will not close unless you apply force with your hands, so even if your hand gets stuck in it, it won't get caught. And when you close it completely, it closes smoothly. Shoji does not open when closed. Easy to manufacture with few components. The sealing ring does not have a piston on the front surface in contact with the sealing ring, and only has a spring seat 30 on the spring side, and the gap between the piston and the cylinder can be used instead of an orifice, so it can be manufactured easily and inexpensively.
