  The present invention relates to a hanging door sliding rail in a semi-automatic sliding door device in which a hanging rail is inclined and attached to a hanging type sliding door provided with a door pocket, and the sliding door is automatically shifted from a door pocket storing position to a closed position. It relates to the mounting structure.

A semi-automatic sliding door device that attaches a hanging rail at an angle and automatically shifts a sliding door from a door pocket storage position to a closed position is widely used.
This sliding door apparatus adopts a construction method in which components such as a vertical frame, a door pocket, a sliding door, and a rail for hanging a sliding door are individually carried in and assembled locally.

  However, when this method is used, there are problems that the assembly is limited in terms of location, and requires labor and time.

  SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the conventional sliding door device, and has as its object to provide a mounting structure of a sliding door suspension rail in a sliding door device that can simplify assembly on site.

  In order to achieve the above object, the sliding door suspension rail mounting structure in the sliding door device of the present invention is configured such that a sliding door suspension rail is inclinedly attached to a sliding door frame member provided with a door pocket on one side, and along the rail. In the mounting structure of the sliding door suspension rail in the sliding door device in which the sliding door is automatically shifted in the closing direction, the tip of the rail is detachably mounted on a rail receiver attached to the upper support frame of the door pocket member. The base end is detachably attached to the upper frame side of the opening frame member by a fixing means such as a screw.

  In this case, the rail support surface of the rail receiver is formed on an inclined surface, and the rail receiver or rail mounting hole for mounting the rail with fixing means such as a screw is formed as a long hole so that the inclination angle of the rail can be adjusted. can do.

  According to the mounting structure of the sliding door suspension rail in the sliding door device of the present invention, the distal end of the sliding door suspension rail is detachably mounted on the rail receiver attached to the upper support frame of the door pocket member, and the base end is disposed. Since the rail is detachably attached to the upper frame side of the opening frame member by screws or the like, when the rail is mounted on the door pocket side, the tip of the rail is attached to the rail receiver attached to the upper support frame of the door pocket member. Can be mounted only by fixing the opening frame side with a fixing means such as a screw, so that on-site assembly can be simplified.

  Also, the rail support surface of the rail receiver is formed on an inclined surface, and the rail receiver or the rail mounting hole for mounting the rail with fixing means such as a screw is formed in an elongated hole, so that the mounting position of the rail can be set in the longitudinal direction of the rail. By simply moving the rail, the inclination angle of the rail can be adjusted.

  Hereinafter, an embodiment of a mounting structure of a sliding door suspension rail in a sliding door device of the present invention will be described with reference to the drawings.

In the figure, a sliding door device 1 is configured such that a sliding door suspension rail 7 is attached to a frame member 2 having a door pocket on one side in an inclined manner, and the sliding door is automatically shifted in the closing direction along the rail. The sliding door frame member 2 includes a door pocket member 3 and an opening frame member 4 on the opposite side of the door pocket member 3, and the two are connected by a connecting plate 5.
The sliding door device 1 is configured such that a sliding door 6 and a rail 7 for suspending the sliding door 6 are detachably attached to the sliding door 6 at an angle.

  The door pocket member 3 is attached to the upper and lower sides of the facing door pockets 10 and 10 by supporting frames 11 and 12 having a U-shaped cross section at intervals so as to allow the sliding door 6 to be inserted, thereby forming a panel structure. The opening frame member 4 on the opposite side is formed in an inverted L-shape by a vertical frame 15 and an upper frame 16 of approximately 1/2 length of the sliding door device.

The suspension rail 7 is a lip-shaped channel steel having a vertically long cross section, and mounts a suspension roller 18 attached to a support bracket 17 attached to an upper portion of the sliding door 6 by a roller support surface 7a on a lower surface.
The suspension rail 7 is attached with the door pocket side slightly higher and the closed side vertical frame 15 side lower.
The mounting procedure in this case is as follows. A rail receiver 20 is mounted on the upper support frame 11 on the side of the door pocket member 3, the tip of the rail 7 is supported on the rail receiver 20, and the base end is mounted on the upper frame 16 of the opening frame member 4. It is mounted on a rail mounting plate 21 which is a mounting portion by a fixing means 22 such as a screw.
The rail support surface of the rail receiver 20 is formed as an inclined surface, and the rail mounting plate 21 or the mounting hole of the rail 7 is formed as an elongated hole extending in the lateral direction as shown in FIG. By moving the mounting position of the rail 7 in the longitudinal direction of the rail 7, the inclination angle of the rail 7 can be adjusted, whereby the inclination angle of the rail 7 can be adjusted by the sliding door 6 at the open position in the door pocket. Adjust to an angle that allows shifting to the closed position by its own weight.

An air damper 25 for controlling a moving speed when the sliding door 6 approaches the closed position is attached to the rail 7. Reference numeral 27 denotes a magnet which is attached to the support bracket 17 of the sliding door 6 in correspondence with the piston rod 26 of the air damper 25. When the sliding door 6 approaches the closed position, the magnet 27 comes into contact with the piston rod 26 and the air damper 25 By compressing the speed, the speed is braked. When the sliding door 6 is moved to the open position, the magnet 27 pulls out the piston rod 26, separates at the maximum position, and the piston rod 26 is left at that position.
Note that the control of the moving speed is not limited to the air damper, and may be, for example, a stepped shape (not shown) in which the vicinity of the closed portion of the rail is substantially flat.

  Further, a free stop mechanism 30 for stopping the sliding door moving in the opening direction at an arbitrary position is attached to the support bracket 17 so as to face the suspension rail 7. When the sliding door 6 is closed, the mounting position is set at a position (hereinafter, referred to as a "free position") beyond the end position of the rail 7 and has a well-known structure (Patent). No. 2683321). The outline is shown in FIG. 9 to FIG.

  The free stop mechanism 30 allows the support shaft 31 to swingably support an elastic locking member 32, which is formed slightly longer than the distance L between the support shaft 31 and the rail 7, and which is suspended by its own weight. At the same time, the contact surface with the rail 7 is formed in an arc shape and formed of a material having a large friction coefficient. Reference numeral 40 denotes a guide roller of a sliding door attached to the floor.

  In the above configuration, the door pocket member 3 of the sliding door frame member 2 and the opening frame member 4 are configured in advance in a factory or the like, and are transported to the site and connected to the connection plate 5 by fixing means 8 such as screws. The assembly of the sliding door frame member 2 is completed. When assembling the door pocket member 3, the rail receiver 20 of the suspension rail 7 is attached in advance. Although the connecting plate 5 is connected by screws 8 from above in the illustrated example, it may be fixed from the side.

Next, mounting of the sliding door suspension rail 7 and mounting of the sliding door 6 are performed.
At this time, the mounting procedure of the rail 7 is such that the tip of the rail 7 is placed on the rail receiver 20 and the opposite side is adjusted to the rail mounting plate 21 mounted on the upper frame 16 of the opening frame member 4 by the screw 22 as described above. Install as possible.
In this case, the air damper 25 is attached to the rail 7 in advance.

Thus, when the sliding door 6 is at the closed position, the piston rod 26 of the air damper 25 is pushed by the magnet 27 attached to the support bracket 17 of the sliding door 6.
Further, the free stop mechanism 30 is located at a position (free position) off the tip of the rail 7.

Next, when the sliding door 6 is moved in the opening direction by hand, the distal end of the elastic locking member 32 of the free stop mechanism 30 is placed on the suspension rail 7, and the distal end 32a thereof is in the position shown in FIGS. As shown in FIG. 12, it is located behind the support shaft 31 and moves to follow the sliding door 6.
Therefore, when the hand is released from the sliding door at an arbitrary position, the elastic locking member 32 is in a stretched state, and the frictional force prevents the backward movement and stops at that position. The same applies when the sliding door is completely opened (FIG. 11).

  The piston rod 26 of the air damper 25 is pulled out by the magnet 27 on the sliding door with the shift of the sliding door 6 in the opening direction, is separated from the magnet 27 at the maximum drawing position, and stops at that position.

  When the sliding door 6 is moved in the closing direction, the sliding door 6 is pulled out by hand, so that the elastic locking member 32 of the free stop mechanism 30 is deformed around the contact point 32a with the rail 7 to move the support shaft 31. And the elastic locking member 32 becomes a position shown by a chain line 32b in FIG. 12, and allows the support shaft 31 to move in the closing direction.

  When the sliding door 6 approaches the closed position, the magnet 27 comes into contact with the piston rod 26 and pushes the rod 26 to shift to the closed position. Thereby, the air damper 25 is compressed, the speed of the sliding door is regulated, and the door is quietly closed.

  As described above, the mounting structure of the sliding door suspension rail in the sliding door device of the present invention has been described based on the embodiment, but the present invention is not limited to the configuration described in the above embodiment, and departs from the gist thereof. The configuration can be appropriately changed within a range not to be performed.

  The mounting structure of the rail for hanging a sliding door in the sliding door device of the present invention can simplify the assembling, and thus can be suitably used for a sliding door device assembled on site.
