DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 and 2 show a free stop device provided on a sliding door according to an embodiment of the present invention. The free stop device of this embodiment includes a stopper 3 which can hold a half open state while stopping the sliding door 1 during opening and closing against the self closing force of the self closing means 2.

The sliding door 1 is provided with a pair of door wheels 12 rotatably on a pair of brackets 11 provided on the upper part of the main body of the sliding door 1, and the self-closing means 2 provided on the door frame 4 on the upper side of the door wheels 12 is provided. It rolls while engaging with the constituent rails 20.

The self-closing means 2 of this embodiment has a structure in which the sliding door 1 is self-closed by utilizing gravity and potential energy, and the rail 20 is inclined so that the direction of the closed end of the sliding door 1 becomes lower. Let me do it. That is, in FIG. 1, the left side is lower than the right side, and the left side is lower.

The stopper 3 is configured to prevent the sliding door 1 from closing by utilizing frictional resistance. That is, as shown in FIG. 3, the stopper 3 of this embodiment has a substantially L-shaped (or U-shaped) base body 31 formed of an appropriate rigid spring material (which is fixed to the bracket 11). ), A support shaft 32 attached to a part of the base 31, and the support shaft 32 on the high side of the rail 20.
And a spring member 33 having an arc shape to which the base end portion is attached in a free rotation state.

The spring member 33 is made of an appropriate spring material (for example, stainless steel, synthetic resin or other rail 20).
The outer peripheral surface of the front end (on the lower side of the rail 20) is formed so as to exert a required spring force by using a material having a relatively good smoothness. A friction member 34 such as rubber or resin is fixed to a part (or the whole) of the side (welding or other methods can be applied according to the material).
Let me. It is preferable that the material used for the friction member 34 has as good abrasion resistance as possible.

A support shaft 32 for mounting a spring member 33
3 is provided at a right position deviated from the center of the spring member 33 in FIG. 3, whereby a moment toward the right is constantly applied to the spring member 33.

[0016] Incidentally, although the stopper 3 in this embodiment is formed in an arc shape, but the invention is not limited to that of this embodiment is applicable for example arcuate shape soil appropriate shape. Further, in this embodiment, the stopper 3 is installed on the bracket 11 to which the positionally upper door wheel 12 is mounted, of the two door wheels 12 on the left and right sides. May be attached to the bracket.

Next, the operation of the free stop device of this embodiment will be described with reference to FIGS.

A handle 1A provided on the main body of the sliding door 1 by hand
When the sliding door 1 is opened by grasping (see FIG. 1) and pushing it to the right to open the sliding door 1, the support shaft 32 side is closer to the opening direction (rightward) with respect to the base 31 due to the entire weight distribution of the stopper 3 (see FIG. 3). .

[0019] Therefore, when the open by moving the left sliding door 1 to the right, but the support shaft 32 of the stopper 3 is also about to move to the right, the spring member 33 and the friction member 3 4 continues a state where it is stopped So, as shown in FIG.
The spring member 33 moves with the sliding door 1 while rolling the rail 20 while being shifted to the left. That is, in this state, the stop force by the stopper 3 does not act.

In this way, the sliding door 1 can be smoothly opened without being disturbed by the stopper 3. However, in order to make the door half-open during the opening, the pushing operation of the sliding door 1 is stopped at a desired position.

Then, when the opening operation of the sliding door 1 is stopped, an inertial force acts on the stopper 3, and a counterclockwise rotation moment (α) is generated about the support shaft 32 as shown in FIG.

Therefore, the stopper 3 pivots slightly to the right and the friction member 34 comes into contact with the rail 20. At this time, the spring force of the stopper 3 and the weight of the sliding door 1 are just above the friction member. since acting 3 4, it can hold the sliding door 1 to the half-open state in a stable state.

To close the sliding door 1 from this half-open state (to release the half-open state), the sliding door 1 may be pushed out in the closing direction and then released.

Then, the friction member 34 riding on the rail 20 comes off the rail 20 and the stopper 3 is shifted to the right as shown in FIG. 6, so that the stopping force disappears.

Since no stop force acts on the door wheel 12 (see FIG. 1), the sliding door 1 can be moved to the left (downward) where the rail 20 is inclined and can be easily closed. The same operation can be performed when the sliding door 1 is further opened from the half-open state.

In this embodiment, the stop operation is performed simply by using the spring force and the frictional force of the friction member.
In addition to this, for example, as shown in FIG. 7, a cylinder 5 is provided, and the cylinder 5 is configured to be electrically operated so that the stop function is not activated in the event of a disaster such as a fire or an earthquake. Of course it is possible. The stop function may be manually performed using a handle and an appropriate mechanism instead of the electric operation.

[0027]

As described above, according to the present invention, the main body of the sliding door provided with the sliding door that rolls while engaging with the rail provided along the opening and closing direction, and the means for self- closing the sliding door.
