[Detailed description of the invention]

[0001]

[Field to which the invention belongs]

 The present invention is a runner that connects a localization door plate and a slide door plate, or in a folding door in which slide door plates are connected to each other, attaches to the upper surface of the slide door plate and engages with an upper rail to guide the slide of the door plate. It is related to the folding door.

[0002]

[Prior art]

 Fig. 1 shows an example of a folding door, which is a hinged door (31) between the upper and lower rails (1) and (2). 4) has been deployed. On the base end side of the localization side door plate (3), pivots (32) (32) are projectingly provided at the upper and lower ends, and the pivots (32) (32) are attached to the rails (1) (2). It is rotatably supported in a fixed position on a bracket (not shown). On the free end side of the slide side door plate (4), runners (8) and (9) are vertically provided so as to project, and slidably engaged with the upper and lower rails (1) and (2).

There are two types of folding doors, one that supports the weight of the door plate by the lower runner and one that suspends the door plate by the upper runner. In FIG. 1, the lower runner (9) supports the weight of the door plate. As shown in FIG. 6, the lower runner (9) has a hollow driving shaft (91) into which a retractable shaft (92) is inserted. , The spring (93) biases the retractable shaft (92) in the protruding direction. An engaging piece (94) that engages with the rails (1) and (2) is provided at the tip of the retractable shaft (92) in a protruding manner. The engagement piece (94) is formed by projecting a flange (96) on a cylindrical body (95) fitted in the groove opening (23) of the groove (21) whose depth is enlarged in the rail (1).

A drill hole (42) is formed in the lower surface of the door plate (4) on the free end side, and the driving shaft portion (91) of the lower runner (9) is driven into the hole (42). The flanges (96) of the lower runner (9) are placed on the support pieces (22) (22) on both sides of the groove opening (23) of the lower rail (2) to support the weight of the door plate. The upper runner (8) may have the same structure as the lower runner (9), and the door plate (4) is moved by the spring force of the upper and lower upper runners (8) and (9). Since the vehicle runs open and closed with (2) being stretched, the upper and lower runners (8) and (9) will not come off the rails (1) and (2).

FIG. 7 shows a suspended upper runner (8). The upper runner (8) is provided with a height adjusting device (82) in a mounting box (81) embedded in the upper end of the slide side door plate (4), and the height adjusting device (82) is used to attach the height adjusting device to the mounting box. A suspension shaft (83) is projected upward through the (81), and rollers (84) (84) are supported on the upper end of the suspension shaft (83) so as to be rotatable in a vertical plane. Insert the suspension shaft (83) of the upper runner (8) into the groove opening (13) of the groove (11) where the depth of the upper rail (1) is enlarged, and insert the rollers (84) (84) in the groove (11). Are placed on the support pieces (12) (12) on both sides of the groove opening (13) to suspend and support the door plate (4). A gap between the upper rail (1) and the door plate (4) is formed by changing a protruding length of the suspension shaft (83) by a height adjusting device (82).

As shown in FIG. 6, opening and closing of the door plate is lighter in the hanging type of FIG. 7 than in supporting the weight of the door by the lower runner (9). However, the mounting of the suspension type upper runner (8) of FIG. 7 requires the notch (43) for embedding the rectangular parallelepiped mounting box (81) containing the height adjusting device (82) to the door plate ( It must be opened in 4), and this process requires skill using chisels, and compared with the process of the drill hole (42) for mounting the lower runner (9) in Fig. 6 described above, Take the trouble. Further, the mounting box (81) of the upper runner (8) has a width and length longer than the diameter of the driving shaft portion (91) of the lower runner (9) in order to accommodate the height adjusting device (82). Opening a notch (43) that becomes larger and fits the mounting box (81) in the door plate (4) reduces the strength of the upper runner mounting portion of the door plate (4). The present invention clarifies a folding door that uses an upper runner, which is a hanging type, yet has a simple structure, requires only a drill hole to process the door plate, and is easy to install.

[0007]

[Means for solving the problem]

 In the folding door of the present invention, the upper runner (5) is screwed into the hollow driving shaft (51) with the screw shaft (52) so that the protruding length can be adjusted, and the roller (53) is attached to the tip end side of the screw shaft (52). The roller (53) is rotatably mounted on the rail support pieces (12) and (12) in the groove (11) of the upper rail (1) to suspend and support the door plate (4). A drill hole (41) is formed in the upper end surface of the door plate (4), and the driving shaft (51) of the upper runner (5) is driven into the hole (41) to prevent the hole from coming off.

[0008]

[Action and effect]

 The upper runner (5) can adjust the height of the roller (53), that is, the hanging height of the door plate (4) by rotating the screw shaft (52) screwed into the driving shaft (51). It is greatly simplified. To install the upper runner (5), a drill hole (41) should be opened in the door plate (4), and the driving shaft (51) of the upper runner (5) should be driven in. It is much simpler and more efficient than the conventional chisel notching for embedding the mounting box (81) of the upper runner (8).

Further, as shown in FIG. 1 and FIG. 6, a folding door is planned in which the upper and lower rails (1) and (2) are stretched by the upper runner (8) and the lower runner (9). When the upper end surface of the plate (4) has a hole for driving the upper runner (8), the upper runner (5) shown in FIG. 3, which is the feature of the present invention, is attached and the folding door is changed. Can be done easily.
