Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a stop device for stopping a door body of a self-closing sliding door at a free position in the middle of an opening / closing path.

[Prior Art] A self-closing sliding door body is generally used in which the sliding door body is manually opened and then automatically closed by a spring or gravity. However, in hospitals, etc., it is necessary to open the door, but I still do not want to open it fully, so there is a demand that it can be stopped in the half-open state during the daytime and can pass freely, so use a wedge and insert it. I'm trying to stop at.

[Problems to be Solved by the Invention] In the self-closing sliding door, the wedge is used to stop the door body, but this requires that the wedge be always located at hand. However, the wedge has the trouble of finding it when it wants to stop, and the wedge not only has to be inserted and removed, but also has the drawback of impairing its appearance.

[Means for Solving Problems] The present invention was devised in order to eliminate this problem in view of such circumstances, that is, it was pivotally supported by shaft support plates provided on the left and right of the upper surface of the door body. In a self-closing sliding door that hangs a hanger car by a rail horizontally installed above the opening and moves it open and close, a guide slope is formed at one end on a lower part corresponding to the rail on the upper part of the door body. A guide member having a plate is fixedly arranged, and in the door body, there is an operating piece protruding upward through a long hole provided on the upper surface side, and a roller is provided on the upper end side of the operating piece. A shaft-supporting piece that is axially supported is provided so as to correspond between the rail and the guide member, and further, the swinging motion of the actuating piece moves up and down the roller, and the roller is moved by the retracting motion to move the rail. Press the guide members against each other to stop the movement and release the stop. The purpose of the present invention is to easily release the stop of the door body at any desired position.

[Embodiment] Next, an embodiment of a stop device for a self-closing sliding door according to the present invention will be described with reference to the drawings. 1 is a door body, and body 1
An L-shaped shaft support plate 2 is attached to the left and right sides of the shaft support plate. A grooved hanger wheel 3 is axially supported on the upper end side of the shaft support plate 2, and the grooved hanger wheel 3, 3 is suspended by a rail 4 horizontally provided at the upper part of the opening so as to follow the rail 4. The main body 1 can be moved. The rail 4 has one end bent upward and the other end fixed to the upper portion of the opening.

On either of the left and right shaft support plates 2, one of the shaft support plates 2 is attached with a vertical piece 6a of a guide member 6 composed of a vertical piece 6a and a horizontal plate 6b corresponding to the lower side of the rail 4. In this case, the horizontal plate 6b of the guide member 6 is arranged so as to have a distance such that the roller 5 which will be described later is held between the horizontal plate 6b and the rail 4. A guide slope 6c for guiding the roller 5 is formed on one end of the horizontal plate 6b of the guide member 6, and the roller 5 guided by the guide slope 6c is fed between the rail 4 and the horizontal plate 6b. Then, the rail 4 and the horizontal plate 6b are pressed into contact with each other to control the movement and stop.

A long hole is provided on the upper surface of the main body 1 in the longitudinal direction, and the operating piece 10 is projected upward from the inside of the main body 1 through the long hole, and the roller 5 is axially supported on the upper end side of the projected operating piece 10. Attach the shaft support piece 10a, and the lower side of the operating piece 10 is the main body 1
A pair of parallel crank pieces 8,8a whose central or intermediate portion is axially supported in a long hole by pins 7,7a from the main body 1 provided on the upper side inside
One end of each of the crank pieces is connected by a pin, and the other ends of the crank pieces 8 and 8a are connected to the upper side of an operation plate 9 vertically inserted in the main body 1 and guided vertically by a pin. The lower part is a pin 13 fitted in a longitudinal long hole 11 provided in the surface plate of the main body 1.
The knob 14 attached to the sliding plate 13 is connected via a.

A shaft support piece 10a provided on the upper end side of the operation piece 10 extends in the moving direction to support the roller 5 in the axial direction. Roller 5
Is normally received at the position of the guide slope 6c of the guide member 6. That is, by moving the sliding plate 13 up and down by the knob 14, the crank pieces 8 and 8a are swung around the pins 7 and 7a through the operation plate 9, and the operating piece 10 is further moved up and down. At this time, the operating piece 10 moves back and forth along a locus of radius centered on the pins 7, 7a of the crank pieces 8, 8a. Therefore, the roller 5 is pushed between the rail 4 and the horizontal plate 6b of the guide member 6 and press-fitted, or retracted to be pulled out from between the rail 4 and the horizontal plate 6b.

[Operation] In the present invention, when it is desired to stop the main body 1 suspended by the rail 4 in the above-described configuration at an arbitrary position, the sliding plate provided on the surface plate of the main body 1
When the knob 14 of 13 is lowered downward along the long hole 11, the operation plate 9 is guided and vertically descends in the main body 1, and at this time, the crank piece
8,8a swings around the pins 7,7a in the elongated holes, and the operating piece 10 connected to the other end of the crank pieces 8,8a is the crank piece 8,8a.
While it is gradually pushed up by the swing of 8a, it is pushed and moved by a radius centered on the pins 7 and 7a. By this movement, the roller 5 axially supported by the shaft support piece 10a at the upper end of the operation piece 10 moves from the position of the guide slope 6c of the horizontal plate 6b to the guide slope 6c along the locus of the crank pieces 8, 8a.
The roller 5 is pushed out and moved along with, and the roller 5 is press-fitted and pressure-contacted between the rail 4 and the horizontal plate 6b, and the movement of the main body 1 is stopped by the friction of the roller 5. That is, it can be stopped at the position where it is desired to stop. Next, when it is desired to release and move it, pulling the knob 14 in the opposite direction has the opposite effect to the above-mentioned action, and the roller 5 is pulled out from between the rail 4 and the horizontal plate 6b, and the pressure contact action is released and the original guidance is obtained. The main body 1 can be moved by returning to above the slope 6c. Therefore, the roller can be stopped at an arbitrary position by pressing the roller between the rail and the horizontal plate of the guide member by a simple operation, and the main body can be moved by releasing the pressing contact.

[Effects] The present invention is a self-closing sliding door in which a hanger car, which is pivotally supported by pivot plates provided on the left and right of the upper surface of the door body as described above, is hung and moved by opening and closing by a rail horizontally installed above the opening. In the lower part corresponding to the rail on the upper side of the door body, a guide member having a horizontal plate having a guide slope formed on one end side is fixed and arranged, and provided on the upper surface side in the door body. Has an operating piece protruding upward through the elongated hole, and an upper end side of the operating piece is provided with a shaft supporting piece for supporting a roller between the rail and the guide member. A self-closing type characterized in that the roller is moved up and down by a swinging motion due to vertical movement, and the roller is moved in a retracting motion to bring the roller into pressure contact with the guide member to stop the movement and to release the stop. It is a stop device for sliding doors, and it can be opened or closed while When you want to stop at the position of, the roller that is pivotally supported by the pivot piece of the operating piece that pushes up and pushes out by swinging motion can be stopped by press-fitting pressure contact between the bottom surface of the rail and the horizontal plate. Can be removed to release the pressure contact. That is, it can be stopped at a desired position and the pressure contact can be easily released, which is convenient. Furthermore, by incorporating it in the door body, there is an effect that the appearance is not damaged.
