BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting type sliding door useful for gates, entrance doors, shutters, partition doors, and the like, and more particularly to a connecting structure for connecting main body panels of the connecting type sliding door.

[0002]

2. Description of the Related Art For example, as shown in Japanese Utility Model Laid-Open No. 2-85798, a main body panel is erected on a plurality of trolleys running on a pair of rails in such a manner that the main body panels are sequentially shifted in the width direction of the rails. A guide groove having a roller running surface is formed on one side surface of the upper and lower horizontal frames of each main body panel, and a roller running on the roller running surface is provided on another side surface of another adjacent main body panel, and the roller runs on the roller running surface. A connection type sliding door is disclosed in which the connection type sliding door is extended substantially in a straight line by running, or the main body panels are stacked and stored.
According to this invention, in order to suppress backlash in the rail width direction of each main body panel, established a guide longitudinal grooves on the upper surface of the door roller body which houses a roller, a flange formed on the upper and lower horizontal rail the By being fitted into the guide vertical groove, the movement of each main body panel in the rail width direction is regulated, and rattling in the width direction is suppressed.

[0003]

However, according to the connection structure of the conventional connection type sliding door, the rattling in the rail width direction requires fitting the flanges of the upper and lower horizontal frames into the guide vertical grooves.
In the height direction of the main body panel
That rattling is not regulated, but if it is set to its length as the flange tip in the groove bottom of the guide flutes contact, it is possible to prevent the height direction of the rattling, this
If the guide sliding resistance of the longitudinal groove and the flange is increased, connection
Operability of the sliding door deteriorates.

Further, since the guide vertical groove is formed in the door bogie main body, the workability of assembling the door bogie main body into the guide groove is reduced unless the opening width of the guide groove of the vertical and horizontal frame is set to be larger than the diameter of the roller. Conversely, if the size is increased, relatively large guide grooves are opened on one side of the upper and lower horizontal frames, and the appearance is deteriorated.

[0005]

Means for Solving the Problems The present inventors have made intensive studies to solve this problem, and as a result, arranged a plurality of trolleys on a pair of rails laid in parallel, in the width direction of the rails.

A roller running surface having an inverted V-shaped cross section is formed on the other book.
Since the roller of the vertical position attached to the body panel are closely by traveling to Russia <br/> over La running surface of the respective, the periphery of the roller contacts the roller running surfaces of the approximately V-shaped cross-section Accordingly, the movement of the roller in the width direction and the height direction is restricted , and rattling of the main body panel can be prevented.

[0007]

1 to 4 show an example of the present invention. The rails 1 and 1 are laid in parallel on a road surface at appropriate intervals, and a plurality of trolleys 2 having rollers running on the rails 1 are arranged below the rails 1.
A vertical frame 21 is integrally provided on the upper surface of each carriage 2, and the positions of the vertical frames 21 in the width direction of the rail 1 do not overlap each other except for the two carriages 2 located on the door stop side. As shown in FIG.

The main body panel 3 is formed into a rectangular frame by upper and lower horizontal frames 4, 5 and left and right vertical frames 6, 7, and an appropriate decorative panel or the like is fitted in the frame. The left and right vertical frames 6, 7 are formed of hollow hollow aluminum or the like, and the lower end of the right vertical frame 7 is open. The vertical frame 21 of the bogie 2 is provided at the lower end of the right vertical frame 7 of each main body panel 3. After insertion, the right vertical frame 7 and the vertical frame 21 are integrally fixed by bolts or the like, and the carriage 2 and the main body panel 3 are integrated. In addition, the main body panel 3 located on the door stop side has the lower ends of the left and right vertical stiles 6 and 7 both open, and the vertical frame 2 of the two bogies 2 and 2 located on the door stop side.
Numerals 1 and 21 are inserted into lower end portions of the left and right vertical frames 6 and 7, and are integrated by bolts or the like.

[0009] upper and lower horizontal rail 4,5 the guide grooves 41 and 51 on one side of the rail 1 the width direction are opened me cotton in the lateral direction throughout the upper and lower horizontal rail 4,5, the guide grooves 41,5
Roller running surfaces 42 and 52 exhibit a cross section V-shape is formed on the 1. Roller running surfaces 42 and 52, as shown in FIG. 1, is formed to face, the upper horizontal rail 4 a V
The roller running surface 42 having a V-shaped cross section is formed on the lower surface of the guide groove 41, and the roller running surface 52 having an inverted V-shaped cross section is formed on

Next, the left vertical frame 6 of each main body panel 3 excluding the door stop side main body panel 3 is made of synthetic resin or the like on the surface opposite to the side where the guide grooves 41 and 51 are formed. Rollers 8 are provided corresponding to the positions of the upper and lower guide grooves 41 and 51, respectively. The upper and lower rollers 8 are fitted into upper and lower guide grooves 41 and 51 formed in another adjacent main body panel 3 so that the rollers 8 run on roller running surfaces 42 and 52. The peripheral edge of the roller 8 is cut off in a tapered shape so that the roller 8 comes into contact with the roller running surfaces 42 and 52 having a substantially V-shaped cross section and rolls. The upper roller 8 is wider than the lower roller 8 because the upper roller 8 receives the load of the main body panel 3 supported by the carriage 2 on one side to some extent.

The roller 8 is provided with a vertical frame cursor 61 having a substantially C-shaped cross section on the door stop side surface of the left vertical frame 6 in a groove provided in the vertical direction of the left vertical frame 6 with both sides thereof. A roller bracket 81 having a substantially L-shaped cross section and supporting the roller 8 is fixedly mounted above and below the vertical frame cursor 61 by bolts or the like. In the figure, reference numeral 83 denotes a roller bracket cover that covers the roller bracket 81.

In mounting the roller 8, first, the roller 8 is inserted into the guide groove 41 formed in the upper horizontal frame 4 of another adjacent main body panel 3 while being obliquely inclined. in a state of being in close contact with the 42, but the roller bracket 81 that is connected to the shaft of the roller 8 to stiles cursor 61 and Hidaritatekamachi 6 is to bolting, this time, the roller 8 to the roller running surface 42 to standing vertically Te, roller position of the roller 8 bracket 8
