Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door that is always biased to move in either a closing direction or an opening direction, and more particularly to a stopping device capable of stopping the sliding door in the middle of the moving range of the sliding door. .

[0002]

2. Description of the Related Art A sliding door of this type is mounted on a rail and movably supported, and is always biased in either a closing direction or an opening direction. For example, inclining the rail,
The sliding door's own weight biases this sliding door in one direction, or ties the sliding door and weight to both ends of the string, hangs this string on a pulley, and hangs this weight to bias this sliding door in one direction. are doing. Therefore, even if the sliding door is opened by a person's force, the sliding door is automatically closed, or even if it is closed by a person's force. That is, only one of closing and opening is automatically performed.

[0003]

By the way, such a sliding door stops in a completely closed state or in a completely opened state. To stop the sliding door at an arbitrary position, It is necessary to attach a special function.
However, the current situation is that there is no simple and durable structure for stopping the sliding door at an arbitrary position.

Therefore, an object of the present invention is to provide a stopping device for a sliding door which has a simple and durable structure and can stop the sliding door at an arbitrary position.

[0005]

In order to solve the above problems, the present invention is mounted on a rail and movably supported, and is always urged in one direction along the rail to move in this one direction. In a device for stopping a sliding door that stops the sliding door in the middle of the moving range of the sliding door, a pendulum body is disposed on the sliding door at a position above the rail, and the pendulum body is pivotally supported so as to reciprocate along the rail. The lower end of the pendulum body is brought into contact with the rail in a vertically long range along the rail to increase the friction between the lower end of the pendulum body and the rail.

[0006]

According to the present invention, the pendulum body is disposed above the rail in the sliding door, and the pendulum body is pivotally supported so as to reciprocate along the rail. The lower end of the pendulum body comes into contact with the rail in a vertically long range along the rail, increasing friction between the lower end and the rail. With the movement of this sliding door, this pendulum body tries to rotate, but since the lower end of this pendulum body is in contact with the rail in the vertically long range, this pendulum body does not rotate smoothly, which creates resistance. , This sliding door stops. When a force in one direction along the rail is applied to the sliding door to defeat the resistance at the tip, the pendulum body rotates. As a result, the lower end of the pendulum moves away from the rail, and the sliding door moves smoothly.

[0007]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a sliding door to which an embodiment of the stopping device of the present invention is applied. In the figure, rail 1
Is fixed to the upper wall surface of the entrance / exit 2, and is inclined with the left side thereof lowered. Two sets of roller units 4 and 5 are fixed to the upper end of the sliding door 3. The left roller unit 4 has two rollers 4a, 4a, and these rollers 4a, 4a are mounted on the rail 1. Similarly, the right roller unit 5 also has two rollers 5a, 5a, and these rollers 5a, 5a are mounted on the rail 1. As a result, the sliding door 3 is movably supported while being suspended below the rail 1.

The roller unit 4 on the left side is lower than the roller unit 5 on the right side. This allows
The upper left side of the sliding door 3 is closer to the rail 1 than the upper right side thereof, and the sliding door 3 is kept horizontal.

Since the left side of the rail 1 is low here,
The sliding door 3 is always biased to the left and moves in the same direction. Therefore, the doorway 2 is normally closed.

The stopping device 6 of this embodiment is attached to the right roller unit 5. The roller unit 5 and the stop device 6 are shown in FIGS. Figure 2
Shows the roller unit 5 and the stopping device 6 as viewed from the front, FIG. 3 shows as viewed from the left side, and FIG. 4 shows as viewed from the right side.

The roller unit 5 has a right-angled support 7, and the right-angled support 7 is fixed to the upper end of the sliding door 3. This right angle support 7 has two rollers 5
a and 5a are pivotally supported, and these rollers 5a and 5a are mounted on the edge 1a of the rail 1.

The stop device 6 includes an L-shaped support member 8 and the L-shaped support member 8.
A pendulum body 9 pivotally supported by a character-shaped support 8 is provided. L
A long hole 8a is formed in the character-shaped support tool 8, and a bolt 10 is passed through the long hole 8a and the hole of the right-angled support tool 7, and a nut 11 is screwed into the bolt 10 to tighten the L-shaped support tool. The tool 8 is fixed to the right-angled support 7. Since the L-shaped support 8 side is the long hole 8a, the nut 11 can be loosened to adjust the vertical positions of the L-shaped support 8 and the pendulum body 9.

An elastic body 12 is fixed to the lower end of the pendulum body 9. As the material of the elastic body 12, hard rubber or synthetic resin is preferable. The bottom surface of the elastic body 12 is flat, and the bottom surface is in contact with the edge 1 a of the rail 1.

In the state shown in FIG. 2, the elastic body 12 of the pendulum body 9 is in contact with the edge 1a of the rail 1 in a vertically long range along the rail 1. As the sliding door 3 moves, the pendulum body 9 tries to rotate, but the elastic body 12 is in the vertically long range, and the rail 1
The pendulum body 9 does not easily rotate because it is in contact with the edge 1a of the. This acts as a resistance against the sliding door 3, and the stopped state of the sliding door 3 is held.

When, for example, a rightward force is applied to the sliding door 3, the pendulum body 9 tends to rotate clockwise. Then, when this rightward force defeats the previous resistance, the pendulum body 9 rotates clockwise. As a result, as shown in FIG. 5, the elastic body 12 of the pendulum body 9 is separated from the edge 1a of the rail 1, and the sliding door 3 smoothly moves to the right.

Similarly, when a leftward force is applied to the sliding door 3 in the state shown in FIG. 2, the pendulum body 9 rotates counterclockwise, and the elastic body 12 of the pendulum body 9 is railed. The sliding door 3 moves smoothly to the left, away from the edge 1a of 1.

Next, while the sliding door 3 is being moved to the right, for example, the sliding door 3 is stopped. At this time,
The pendulum body 9 is in the state shown in FIG. After that, when the sliding door 3 is slightly moved in the opposite left direction, the pendulum body 9 rotates counterclockwise to the state shown in FIG. 2, and the stopped state of the sliding door 3 is held.

Similarly, when the sliding door 3 is stopped while the sliding door 3 is being moved leftward and the sliding door 3 is slightly moved in the opposite right direction, the pendulum body 9 is shown in FIG. The sliding door 3 is held in the stopped state.

Therefore, the sliding door 3 can be stopped not only in one of the open state and the closed state but also in the middle thereof, and the so-called half-open state can be maintained. Moreover, when a force is applied to the sliding door 3 in either the left or right direction, the sliding door 3 moves smoothly, which impairs the automation of closing or opening, which is the original advantage of the sliding door 3. Never.

The present invention is not limited to the above embodiment, but can be variously modified. For example,
The position of the pendulum body 9 may be changed so that the elastic body 12 of the pendulum body 9 is brought into contact with the inner side surface 1b of the rail 1 shown in FIG. Alternatively, instead of the rail 1 and the L-shaped support 8, the U-shaped rail 13 and L as shown in FIG.
The pendulum body 9 may be moved upward using the character-shaped support tool 14 to bring the elastic body 12 into contact with the upper side surface 13b of the rail 13.

Further, the width of the pendulum body or the elastic body may be appropriately changed to adjust the magnitude of the force for moving the sliding door in the stopped state. Alternatively, the material can be adjusted by appropriately selecting the material of the elastic body. Not only hard rubber or synthetic resin, other materials may be applied, but the pendulum body and the elastic body are the same. The material may be integrated.

Further, the present invention can be applied even when the rail is below the sliding door. Further, the lower end of the pendulum body is not limited to the contact with the rail, and one parallel to the rail may be used instead.

Further, the present invention is applied not only to a sliding door biased in one direction by tilting the rail but also to a sliding door biased in one direction by a weight or a spring to keep the rail horizontal. can do.

[0025]

As described above, the sliding door stopping device according to the present invention includes at least a pendulum body, and increases the friction between the lower end of the pendulum body and the rail. Therefore, the sliding door stop device has a simple and durable structure. It can be stopped at any position.
