[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sliding door device, and more particularly to a hanging type sliding door provided with a door pocket, in which a suspension rail is inclined and mounted, and the sliding door is automatically moved from a door pocket storage position (hereinafter referred to as an open position) to a closed position. The present invention relates to a type sliding door device.
[0002]
[Prior art]
A semi-automatic sliding door is already generally used. In this structure, the suspension rail that supports the suspension of the sliding door is mounted with a low inclination in the closing direction, and when opening it is necessary to pull the sliding door sideways by hand, but when closing, it is automatically released by releasing the hand. It is intended to close.
[0003]
At this time, when the sliding door automatically closes due to its own weight, there is a considerable speed at the closed position, and there is a risk that an impact sound may be generated at the time of closing, and there is a risk that a hand or body is caught. For this reason, in order to buffer this, means for attaching an air damper and absorbing the impact force is adopted.
Moreover, in the sliding door apparatus provided with the door pocket, the sliding door holding member which hold | maintains this in the open position of a sliding door is provided.
[0004]
[Problems to be solved by the invention]
The air damper may require adjustment or replacement for long-term use. In this case, when the sliding door device has a structure including a door pocket, it is very difficult to remove and replace them. Moreover, although the transition speed from the open position to the closing direction of the sliding door is adjusted by the mounting angle of the hanging rail, it may be necessary to readjust this during use.
In view of this, the present invention makes it easy to adjust the mounting angle of the rail and the attachment / detachment for adjusting the air damper even in a sliding door device having a door pocket, and to easily stop the sliding door at an arbitrary position. The purpose is to equalize.

[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the figure, the sliding door device 1 includes an outer frame 2, a door pocket 3 attached to one side of the outer frame 2, a sliding door 4 and a hanging rail 5 for the sliding door 4. However, 2a shows the upper frame, 2b shows the vertical frame on the open side, 2c shows the vertical frame on the door pocket side, and the upper frame 2a and the vertical frames 2b and 2c are attached to the upper frame 2a as shown in FIGS. The mounting piece 2d is attached to the joint with the vertical frame, and the mounting piece and the vertical frame are detachably connected to each other by a wedge 6.
[0008]
7 is a suspension bracket attached to the sliding door 4, 8 is a suspension roller, 10 is attached to the suspension rail 5, and an air damper that brakes the moving speed of the sliding door 4 when approaching the closed position from the open position. Reference numeral 10b denotes a magnet attached to the bracket 7 so as to correspond to the piston rod 10a of the air damper 10. When approaching the closed position of the sliding door, the magnet 10b comes into contact with the piston rod 10a, and the air damper 10 The speed is braked by compressing. When the sliding door 4 moves in the opening direction, the magnet 10b pulls out the piston rod 10a, moves away from the maximum position, and leaves the piston rod 10a in that state.
[0009]
The suspension rail 5 is a lip-shaped groove steel having a vertically long cross section, and is attached with a slightly higher door pocket side and a lower open side vertical frame 2b side. In this case, the mounting procedure is as follows. The rail receiver 11 that supports the upper horizontal surface of the rail 5 is attached to the door side of the upper frame 2a, and the opposite side of the rail 5 is attached to and detached from the rail mounting plate 23 provided on the upper frame 2a by screws 12. Install as possible. The inclination angle of the rail 5 is an angle at which the sliding door 4 in the open position (position in the door pocket) can move to the closed position by its own weight.
[0010]
Also attached to face a free stop mechanism 20 for stopping and holding at any position the sliding door 4 which is open to the bracket 7 to the rail 5. In the closed position of the sliding door 4, the attachment position is attached to a position (free position) that passes through the end position of the hanging rail 5, and the structure uses a well-known structure (Japanese Patent No. 2683321). The outline is shown in FIGS.
[0011]
The free stop mechanism 20 supports an elastic locking member 22 on a support shaft 21 so as to be swingable. The elastic stop member is formed slightly longer than the distance L between the support shaft 21 and the rail 5 and is suspended by its own weight. The caulking and the contact surface with the rail 5 are formed in an arc shape and are made of a material having a large friction coefficient.
In the figure, reference numeral 25 denotes a guide roller of the sliding door 4 attached to the floor surface.
[0012]
In the above configuration, when the sliding door 4 is in the closed position, the free stop mechanism 20 is in a position away from the end portion 5a of the hanging rail 5, that is, in a free position, as shown in FIG. The member 22 is in a suspended state, and the sliding door 4 is in contact with the vertical frame 2b by its own weight.
[0013]
In this state, when the sliding door 4 is moved in the opening direction, the tip of the elastic locking member 22 of the free stop mechanism 20 is placed on the hanging rail 5, and the tip 22 a is shown in FIGS. 9 and 11. As shown, it is located rearward from the support shaft 21 and shifts to the sliding door 4. Therefore, even if the hand is released from the sliding door 4 at an arbitrary position, the elastic locking member 22 is in a stretched state, and the reverse movement is prevented by the frictional force and stops at that position.
[0014]
At this time, the magnet 10b that is in contact with the piston rod 10a of the air damper 10 pulls out the piston rod, leaves the piston rod 10a at the maximum drawing position, and the magnet 10b moves while leaving the piston rod 10a in that state.
[0015]
Further moving the sliding door 4 in the opening direction means that the elastic locking member 22 moves following the sliding door 4 without resistance and reaches the fully open position (FIG. 10). The elastic locking member 22 of the top mechanism 20 prevents the reverse movement as described above, and the sliding door 4 stops at its open position.
[0016]
Next, when moving the sliding door 4 in the closing direction, the elastic locking member 22 of the free stop mechanism 20 is deformed and compressed around the contact point 22a with the rail 5 by pulling the sliding door 4 by hand. The elastic locking member 22 is allowed to move to the closing direction of the support shaft 21 by allowing the support shaft 21 to move and to be in the position 22b shown by the chain line.
That is, the sliding door 4 moves in the closing direction by its own weight.
[0017]
As the sliding door 4 approaches the closed position, the magnet 10a comes into contact with the piston rod of the air damper 10 and compresses the air damper 10, whereby the speed is braked and the magnet 10a is closed gently and slowly.
[0018]
The air damper 10 may malfunction due to air leakage or the like due to long-term use, and may require readjustment or replacement. The air damper 10 is attached to a suspension rail 5, and the rail 5 is supported at its front end by a rail receiver 11 at the door side and attached at the opposite side by a screw 12. Therefore, it is easy to remove the screw by removing the screw. Can be taken out. Therefore, operations such as adjustment and replacement of the air damper 10 can be easily performed.
[0019]
The traveling speed due to the weight of the sliding door 4 is determined by the inclination angle of the hanging rail 5. Therefore, the speed can be adjusted by adjusting the mounting angle of the rail 5, and when the speed needs to be readjusted during use, it can be easily adjusted by adjusting the insertion hole of the screw 12.
[0020]
