Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door having a biasing means for normally holding the door in a closed position and having a free stop mechanism capable of stopping at an arbitrary position.

[0002]

2. Description of the Related Art As shown in FIG. 13, such a conventional free stop mechanism is provided on a door roller (3) itself attached to a hanging bracket (11) of a door plate (1). The recesses (31) are provided at a plurality of positions in the shaft hole of the door roller (3) in which the support shaft (30) is fitted,
The needle shaft (32) is housed in the recess (31).

Both ends of the recess (31) are enlarged so that the needle shaft (32) can idle, and the center of the bottom surface of the recess (31) and the support shaft are supported.
The gap S with the (30) is a little smaller than the diameter of the needle shaft (32). By inserting the needle shaft (32) into the gap S, the door roller (3) is locked on the rail (2) and the door plate (1) is locked.
Can be held in any open position. When a force is applied to the door plate (1) in the opening direction or the closing direction, the needle shaft (32) pushes the gap S open and moves to the opposite side of the recess (31),
The lock of (3) is released, and the door plate (1) is closed or opened.

[0004]

Since the free stop mechanism is built in the door roller (3), the size of each component is greatly restricted. Needle shaft (32) has a diameter of 2 mm
As a result, the clearance S between the recess (31) of the door roller (3) and the support shaft (30) must be reduced, and the needle shaft (32) is forced to repeatedly pass through this narrow clearance S. , Within a short period of time, the engagement force between the needle shaft (32) and the gap S becomes loose,
There was a problem that the free stop mechanism did not function and that the force required to unlock the lock was required at both opening and closing. The present invention clarifies a sliding door having a free stop mechanism that can solve the above problems.

[0005]

A free stop mechanism, which is a feature of the present invention, axially supports an elastic locking member (4) so as to be movable and swingable together with a door plate (1), and the elastic locking member (4) is , The rail (2) or a long member arranged parallel to the rail (2) in a state of being slightly inclined by the self-weight of the elastic locking member (4) or the biasing of the spring
(Hereinafter, a rail or a long member is referred to as a “counterpart member”).

[0006]

[Operation and effect] In the posture in which the free end of the elastic locking member (4) is located on the closing side of the door plate (1) with respect to the support shaft (40) supporting the locking member, the door plate (1) is closed. Even if it tries to slide in the direction, due to the friction between the elastic locking member (4) and the rail (2), the elastic locking member (4) is stretched between the support shaft (40) and the rail (2) and the soft brake is pulled. However, sliding of the door plate (1) is prevented. Therefore, the door plate (1) can be stopped at any position on the rail (2). The door plate (1) is free in the opening direction.

A door plate with a soft brake applied in the closing direction
When force is applied to (1) in the closing direction by hand, the door plate (1)
Along with this, the support shaft (40) moves to the door plate closing side, but the free end of the elastic locking member (4) is prevented from moving in the door plate closing direction by friction with the counterpart member, but is elastically locked. Material (4)
Is elastically deformed by being compressed between the support shaft (40) and the mating member, and when a force is further applied in the closing direction in this state, the support shaft (4
The free end of the elastic locking member (4) moves to the door plate opening side with respect to the support shaft (40) along with the shift of (0) to the door plate closing side, whereby the sliding door can be closed without trouble.

At the fully closed position of the door plate (1), if the end of the mating member is cut so that the elastic locking member (4) does not come into contact with the mating member, the door plate (1) will be removed. When opening from the fully closed position, the brake is not effective even when opening.
It can be opened lightly only by the frictional force between the door roller (3) and the rail (2), and even a child or a physically handicapped person can easily open the door.

As described above, since the free stop mechanism, which is a feature of the sliding door of the present invention, is constructed separately from the door roller (3), the size of each component is not so limited, and it is sufficient. In addition, parts can be designed in consideration of durability, and a reliable free stop function can be realized over a long period of time.
Further, since the elastic locking member (4) may be pivotally supported on the door plate hanging bracket (11) either directly on the door plate hanging bracket (11) or via the mounting plate (12), the existing sliding door It's also easy to implement.

EXAMPLE As shown in FIG. 1, two door rollers (3) are attached to the upper end of a door plate (1) via a bracket (11), and the door wheels (3) are placed on a rail (2). The door plate (1) is slidably suspended. A cover (not shown) is provided over the entire length of the transition path of the rail (2) and the door roller (3). The rail (2) is inclined downward with a slope of about 1/200 on the closing side of the sliding door.

An elastic locking member (4) is provided on the bracket (11) so as to be swingable within the sliding transition surface of the door plate (11) and contactable with the rail (2). In the embodiment, a mounting plate (12) is screwed and fixed to the door plate (1) closing side end of the bracket (11), and the supporting shaft (40) is horizontally attached to the mounting plate (12) perpendicular to the rail (2). And the supporting shaft (40) is rotatably supported by penetrating the upper portion of the vertically long elastic locking member (4).

The length from the support shaft (40) to the lower free end of the elastic locking member (4) is the support shaft (40).
Slightly longer than the distance from the rail to the elastic locking member
The lower end of (4) is in contact with the rail (2) in a slightly inclined state.

As shown in FIG. 2, at the fully closed position of the door plate (1), the elastic locking member (4) is disengaged from the rail (2) so that the end of the rail (2) is attached to the door plate (1). It is cut shorter than the entire length, or part of the upper surface of the rail (2) is cut.

However, as shown by the solid line in FIG. 5, in the state where the free end of the elastic locking member (4) is located closer to the door plate (1) than the support shaft (40), the rail (2) is. Even if the door plate (1) tries to slide in the closing direction due to the inclination of the door plate and its own weight, the friction between the elastic locking member (4) and the rail (2) causes the support shaft (40) and the rail (2) to move. ), The elastic locking member (4) is stretched and the soft brake works to prevent the door plate (1) from sliding. Therefore, the door plate (1) can be stopped at any position on the rail (2). In this state, the door plate
(1) is free in the opening direction.

When the door plate (1) is pushed in the closing direction by hand, the support shaft (40) supporting the elastic locking member (4) moves to the door plate closing side together with the door plate (1), The free end of the stop member (4) is prevented from moving in the closing direction of the sliding door due to friction with the counterpart member.

When the door plate (1) is further pushed in this state in the closing direction, the elastic locking member (4) is elastically deformed by being compressed between the support shaft (40) and the mating member, and the support shaft (40 The free end of the elastic locking member (4) moves to the door plate opening side with respect to the support shaft (40) along with the shift of () to the door plate closing side.

When the door plate (1) reaches the fully closed position, the elastic locking member (4) is disengaged from the rail (2) and the elastic locking member (4) becomes free. When the door plate (1) is opened from the fully closed position, the elastic locking member (4) is pulled by the support shaft (40), and its lower free end slides on the rail (2), and the door plate (1) On the other hand, the brake is not effective and the door plate (1) can be lightly opened.

When the door plate (1) is opened to an arbitrary position and the hand is released from the door plate (1), the free end of the elastic locking member (4) is located closer to the door plate (1) than the support shaft (40). Therefore, as described above, the tip of the elastic locking member (4) is in contact with the rail.
Due to the friction with (2), the soft brake works in the closing direction of the door plate (1), and the door plate (1) can be stopped at its open position.

FIG. 6 shows an embodiment in which the mounting height position of the elastic locking member (4) can be adjusted.
