Description

[Detailed description of the invention] This invention has two guide rails that are pivoted on the ceiling of the doorway so that they can expand and contract in conjunction with each other, and two sliding doors can be slid on these guide rails in the length direction of the rails. The present invention relates to a temporary stop device for a flat door which is suspended vertically and whose surface is flat when closed, and whose front and rear surfaces are different in height when opened by means of an expanded guide rail.

Regarding flat doors, there are Japanese Patent Applications No. 51-148555 previously filed by the present applicant, and the present invention is based on the movement inertia of the guide rail that expands when each sliding door is opened in these flat door devices. To provide a convenient temporary stop device for a flat door that prevents other sliding doors from moving in the opening direction due to force and eliminates the need for accidental contact between sliding doors and the closing operation of sliding doors opened due to inertial force. It is in.

In order to further achieve this objective, the present invention provides a removable stop member between the sliding door and another fixed member to stop the movement of the sliding door, and places the locking/disengaging operation portion of the stop member at a suitable location on the door. For example, the operating end is located within the handle of a sliding door.

The details of the present invention will be explained in more detail based on an embodiment shown in the drawings. Due to the expanding and contracting movement of the guide rail 1, the surface of the sliding door becomes flat when the sliding door 2 is closed, and when the sliding door is opened, the front and back are at different levels due to the expanding movement of the rail, and the sliding door 2 moves in the width direction of the doorway. It allows for the movement of

Therefore, in such a flat door device, a kicker 4 is provided protrudingly on the upper surface of the sliding door 2 or on the upper surface of the trochanter pivot arm 3 extending from the upper end of the sliding door, and the kicker 4 is
For example, a stopper 5, which is a stopping member that can be engaged with and detached from the kicker 4, is installed vertically movably on the side surface of the guide rail 1, which is a fixed member, or on the inner surface of the upper part of the door, so that the kicker 4 can be brought into contact with the stopper 5. This prevents the sliding door 2 provided with the kicker 4 from being opened inadvertently.

The illustrated stopper 5 has a floating hole 6 provided on the side surface of the guide rail 1 so that the stopper 5 can move up and down.
A shaped member is inserted so that the locking head 7 is locked at the edge of the floating hole 60, and the lower end side of the rail 1 on the center side in the length direction is made into a tapered part 8, and the lower edge on the other side is made into a tapered part 8. The contact portion is 9.

The stopper 5 is moved upward by being pushed from below, the lower end of which locks against the kicker 4 is released, and the push-up force from below is released so that the stopper 5 falls under its own weight and is placed at the solid line position in the figure. ing.

As shown in the figure, the stopper 5 lifting/operating section is constructed by installing a rod 10 on the sliding door 2 for pushing up the stopper 5, and also having a stopping member with one end positioned at a suitable location on the sliding door 2, for example, inside the handle 11. Operation rod 12 which is the engagement/disengagement operation part of
has been established.

That is, a mounting plate 13 attached to the inner surface of the sliding door is provided with a floating hole 14, into which the rod 10 is inserted, so that the rod 10 can move up and down within or inside the sliding door.

The tip of the rod has a floating hole 14 depending on the stopper mounting position.
It is bent from the top and positioned at the bottom end of the stopper.

When the stopper 5 is attached to the side of the guide rail 1 on the front side, the new curved part at the upper end of the rod may be short as shown in the figure, but when it is attached to the side of the guide rail 1 on the rear side, it should be extended to that position. be.

In addition, the lower end of the rod 10 is pivoted by a pin 17 to one end of an L-shaped connecting rod 16 rotatably attached to the sliding door 2 by a support shaft 15 at the bent portion so that the rod 10 can be moved upward. 1
6. The other end is fitted with the pin 20 of the operating rod 12 which is placed horizontally by placing one end inside the handle 11 of the sliding door 2 and inserting the other end into the support floating hole 19 into the elongated hole 18 provided therein. It is connected.

However, when trying to push the two sliding doors hanging from the two guide rails 1, 1 in the opening direction, when you put your hand on the handle 11 and push it in the direction of the arrow, your hand will simultaneously push the end of the operating rod 12. As a result, the operating rod 12 moves laterally, and in response, the pin 20 rotates the L-shaped connecting rod 16 in the direction of the arrow to push the lower end of the rod 10 upward.

As the rod 10 moves upward, its tip moves to the left in the figure while pushing the abutment part 9 of the stopper 5 upward, and as a result, the following kicker 4 enters the lower side of the stopper 5 and pushes the upper end of the rod 10 and /Or the stopper 5 is prevented from descending by the kicker 4.

Next, if the sliding door 2 is further moved to the left in this state, the upper end of the rod 10 and the kicker 4 are separated from the lower end of the stopper 5, and the sliding door 2 can be moved laterally under the guide rail.

Also, when returning to the closing direction, since the lower end of the stopper 5 is provided with a tapered part 8, just by pushing the handle, the kicker 4 will be located on the right side of the stopper 5 in the figure, and the tip of the rod 10 will be located below the stopper 5. reach.

As described above, the temporary stop device according to the present invention prevents the sliding door 2 on the other side from moving due to the inertial force at the time of opening, even if the guide rail 1 expands at the same time as the sliding door is pushed and opened.
Accidental contact damage between the sliding doors 2 when opened can be prevented, and there is no need to close the opened sliding doors, which is convenient.

Furthermore, by positioning one end of the operating rod 12 in the handle 11 of the sliding door 2, the opening movement of the stopper 5 and the opening of the sliding door can be performed at the same time, which facilitates the operation of the flat door. Since the lower end shape of the rod 10, the upper end shape of the rod 10, and the kicker 4 are combined as described above, the pusher 4 can be accurately adjusted to the vertical movement of the stopper 5.
is engaged and disengaged, and the sliding door 2 is stopped.
