Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a bracket structure for a hanger sliding door in which the sliding door is suspended from a guide rail so as to be movable in opening and closing.

[Prior art and problems to be solved by the invention] Generally,
This type of hanger sliding door opens and closes by a hanger roller rotatably installed at the upper end of the sliding door running on a guide rail installed horizontally between the left and right vertical frames. There is a device in which the guide rail is covered by front and rear inspection panels, and its height can be adjusted by moving a rail height adjustment screw that contacts the guide rail from below. However, in the past, dedicated brackets were prepared to install the front and rear inspection panels and the rail height adjustment screws, and these brackets were installed in advance at predetermined positions on the vertical frame.

As a result, the number of parts per unit increased, and the number of assembly steps also increased, contributing to an increase in costs.

[Means for Solving the Problems] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a bracket structure for a hanger sliding door that can eliminate these drawbacks. In a hanger sliding door that opens and closes by running on a guide rail installed horizontally between the left and right vertical frames, a hanger roller rotatably installed in the left and right vertical frames opens and closes. The mounting screws for the front and rear inspection panels that cover the rail are engaged with the rail height adjustment screws that contact the guide rail from below and adjust the height of the guide rail by moving forward and backward. The adjustment screw attachment is characterized by being integrally provided with the adjustment screw attachment section.

With this configuration, the present invention can reduce the number of parts and improve assembly workability.

[Example] Next, in a drawing explaining an embodiment of the present invention based on the drawings, l is a sliding door, and a hanger roller 2 is rotatably supported on the upper stile 1a of the sliding door l. A pair of roller brackets 3 are integrally provided, and the sliding door l
The hanger rollers 2 are opened and closed by running on a guide rail 4 placed horizontally above the opening, but these structures are the same as before.

Reference numeral 5 denotes a sliding door closer attached to the end of the kite rail 4 on the door tip side, and the drum portion 5a of the sliding door closer 5
One end of the toothed belt 6, which is hung around the door, is locked to the door end roller bracket 3, and the other end is locked to the door bottom roller bracket 3 via a driven pulley 7. That is, the sliding door closer 5 has a drum portion 5a that accompanies the opening operation of the sliding door 1.
The drum part 5a is reversed by the door-closing force accumulated in an internal bomber (not shown) by the rotation of the drum part 5a, thereby forming a so-called self-closing sliding door that automatically closes the sliding door 1.

Reference numeral 8 denotes a locking rod that is internally movable up and down at the end of the sliding door 1, and the locking rod 8 moves up and down in response to the locking and unlocking operations of the locking operation mechanism 9 connected to the base end. The tip of the protruding tip protrudes and retracts from the upper end of the sliding door 1 through a Rondo hole 1b drilled in the upper surface of the sliding door 1, and when the sliding door 1 is fully opened and the lock is operated, the tip that protrudes out of the way. The opening operation of the sliding door 1 is regulated by the locking action of a rod receiver 2 attached to the upper end of the door end side vertical frame 10 via a bracket 11, which will be described later.

The rod receiver 12 has a recess 1 that opens toward the rear end of the door.
2a, and a fixing piece 12b is protruded from each of the left and right ends, and a locking lever 12c for locking the locking rod 8 is attached to the support shaft 12d at the front end side. It is provided so that it can freely swing back and forth via the. That is, the locking lever 12c is normally held in a position in which it contacts the locking piece 12f formed on the front edge of the rod receiver 12 by the biasing force of the bullet 12e wound around the support shaft 12d.

In this position, by closing the opening of the recess 12a, the locking rod 8 that fits into the recess 12a is locked by the locking operation at the time of closing, and the opening operation of the sliding door 1 is restricted. When the sliding door 1 is closed with the locking lever 8 protruding, the locking lever 12c comes into contact with the locking rod 8 and retreats against the biasing force of the bullet 12e into the recess 12a of the locking rod 8. Allows intrusion,
Furthermore, in this retracted position, the opening operation of the sliding door 1 is allowed without locking the locking rod 8.

On the other hand, the bracket 11 is attached to the rod holder formed in a concave shape to avoid interference with the locking rod 8.
a. The rod holder is attached to a part 11b which protrudes from the front end of the front end of the guide rail 4 with a gap therebetween. The adjustment screw is attached to a part 11b, and the adjustment screw is attached to a part 11b that rises upward from the outer edge of the part 11b. It has a rail abutting part 11c integrally, and inspection panel mounting parts 13 and 14 are welded to both left and right ends of the rod receiver mounting part 11a, respectively. That is, in addition to the rod holder 12, the bracket 11 includes a rail height adjustment screw 15 whose tip contacts the guide rail 4 from below and adjusts the height of the guide rail 4 by advancing and retracting the screw. Inspection panels 16 and 17 that cover the guide rail 4 from the front and back are attached via screws 16a and 17a, and the rail contact portion 11c is attached to the guide rail 4 by screws. By coming into contact with the back surface of the guide rail 4, the guide rail 4 is temporarily held during one assembly operation and the guide rail 4 is guided in vertical movement during the height adjustment operation.

Furthermore, the bracket 11 has contact pieces 11d bent at the rear edge of the rail contact portion 11c to contact the left and right front positions of the vertical frame 10, respectively, and a front inspection panel attached to the front side. When installing the bracket 11, the surface contact pieces 13a are brought into contact with the vertical frame 10, so that the bracket 11 can be installed in a proper posture. The vertical frame 10 can be easily maintained in a horizontal position.

Further, the vertical and horizontal positioning of the bracket 11 can be easily performed by fitting the bracket fixedly into the groove (door stop) 10a of the vertical frame 10 by bringing it into contact with the seat 18. It looks like this. That is, the bracket mounting seat 18 connects the guide rail 4 to the vertical frame 10.
The attachment of the bracket 19 fixed to the side constitutes a seat.

Further, its front end side protrudes from the groove 10a, and the protruding lower end of the rod receiver positions the bracket 11 in the vertical direction by coming into contact with the upper surface of the mounting portion 11a;
Further, the dimensions are set so that the side surface of the protruding portion abuts the tip end edge of the abutting piece lld, thereby positioning the bracket 1 in the left-right direction. Note that 20 is a welded portion of the bracket 11.

In the embodiment of the present invention configured as described above, the vertical frame 1
The bracket 11 attached to the rod receiver 12,
The rail height adjustment screw 15 and the inspection panels 16, 17 will be mounted on the bracket. Therefore, each member can be attached by simply preparing the bracket 11 and attaching it to the vertical frame 10, without preparing a bracket for each member to attach the above-mentioned members as in the conventional case. As a result, the number of parts per unit is significantly reduced, and the assembly work process is also significantly simplified, which can greatly contribute to reducing the cost of the hanger sliding door. Moreover, by providing the rail abutting portion 11c, the bracket 1■ can also be used as a temporary holding member for the guide rail 4 during assembly work and as a vertical movement guide member for the guide rail 4 during height adjustment work. Furthermore, the number of parts and the assembly process can be reduced, which is extremely convenient.

[Operations and Effects] In short, the present invention is constructed as described above, and is provided with front and rear inspection panels that cover the guide rail from the front and back, and a rail height adjustment screw that adjusts the height of the guide rail. However, the front and rear inspection panels and rail height adjustment screws are attached to a bracket that integrally includes a mounting section for both members. Therefore, unlike the conventional method, it is not necessary to prepare special brackets for attaching front and rear inspection panels and rail height adjustment screws, and it is possible to attach both members using only the above-mentioned bracket that also serves as a bracket. As a result, the number of parts can be significantly reduced, and the assembly process can be simplified by reducing the number of parts, thereby contributing to a significant cost reduction in the hanger sliding door.
