BACKGROUND OF THE INVENTION The present invention relates to a side pillar that is erected near the closed end side of a hanging door such as an automatic door.
The present invention relates to an improvement of a roller-type door guide used for guiding the lower end of the door when it is opened and closed by being attached to a corner of the floor.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 4 and 5A and 5B, a roller type door guide for a hanging door is known. In this case, the substrate a is a flat plate portion. The standing plate portion c attached to the side pillar d is erected from one side end of b to form an L shape, and the other side end of the flat plate portion b is
A roller supporting plate (not shown) whose distance from the standing plate portion b is adjustable is fixed, and a roller shaft bearing rod (not shown) standing on the roller supporting plate is hung so that it can travel between the roller plate and the standing plate portion c. In the door e, a guide roller f that is in contact with the lower end side surface e ′ and rolls is pivotally supported.

The roller type door guide is attached to the corner portion of the side pillar d and the floor surface g, and guides the lower end side surface e'of the hanging door e by the guide roller f when opening and closing the hanging door e. Although the undesired swing of the hanging door e in the thickness direction is prevented, in practice, when the hanging door e is hung on the base rail i by the hanger roller h, the hanging door e is In FIGS. 5A and 5B, which are sectional views taken along the line BB ′ in FIG. 4, the wind pressure from the side opposite to the guide roller, that is, the left side in FIGS. Unless they are pressed by force and are in contact with each other, they do not always come into contact with the guide roller f to open and close. In other words, when not only the guide roller f is opened and closed but also the guide roller f is not contacted,
By contacting the sliding contact portion j of the standing plate portion c of the substrate a, the opening / closing operation is performed while swinging leftward or rightward in the drawing.

From the positional relationship between the suspension door e and the hanger roller h, the door eccentric suspension type shown in FIG.
Although it can be divided into two types, the door center hanging type in FIG. 3B, the force F that the hanging door e is pressed against the standing plate portion c by the swing is larger in the door eccentric hanging type than in the door center hanging type. Further, in the door eccentric suspension type, the longer the distance between the center k of the suspension door e and the center 1 of the hanger roller h, the larger the value of F becomes. Further, the size of the same F becomes smaller as the height of the hanging door e, that is, the distance from the hanger roller h to the roller door guide becomes longer.

On the other hand, on the lower end surface e'of the door which comes into contact with the guide roller f, smooth opening and closing movement can be obtained by the rotation of the guide roller f. Although the cushioning material m made of mohair or the like certainly has a sufficient cushioning effect against the swing of the suspension door e at the initial stage of mounting, in reality, as described above, the suspension door e swings left and right while opening and closing. Since it moves, the door e comes into direct contact with the sliding contact portion j due to wear relatively quickly.

Therefore, even if the door comes into direct contact with the sliding contact portion j, the sliding door j is not easily scratched. However, the abrasion powder of the synthetic resin material due to the sliding contact adheres to the hanging door e, or the synthetic resin material is completely consumed depending on the frequency of opening / closing, and the standing plate portion c, which is generally made of metal, is hung. The door e comes into contact, which results in the generation of sliding noise,
The hanging door e itself is damaged, and in the worst case, the hanging door e must be replaced.

Further, as a roller type door guide, one shown in FIG. 6 is also known. In this case, a through hole n is opened at the center of the standing plate portion c of the substrate a, and the through hole n is formed. At the opening edge, brackets o and p are bent in parallel from the upper part and the lower part, respectively.
Further, a window hole r is provided in a side pillar d, a wall or the like to which the standing plate portion c is attached, and a guide roller and brackets o and p are installed in the window hole r. As a result, the guide roller q moves from the standing plate portion c to the guide roller f.
The size s protruding to the side can be appropriately reduced.

However, in the above-mentioned roller type door guide, since the window hole r has to be opened in the side pillar d, the wall or the like and close to the floor surface g, the window hole r is drilled. It is necessary to perform work such as machining with a hole to make a round hole, or cutting with a file to make a square hole, and since it is also difficult to work, considerable effort and effort must be applied.

Therefore, as shown in FIG. 7, separate substrates a,
Two roller-type door guides formed by axially supporting guide rollers f and q are provided on a ', respectively, on the side pillar d and the side surface of the wall.
It is exposed to the opening side and installed, or as shown in FIG. 8, guide rollers f and q are pivotally supported respectively on the floor surface side of one substrate a and the opening side of the side pillar d or the wall to be integrated. A structure may be adopted so that the same function as that of FIG. 7 is made to work. However, in this case, not only the guide roller q disposed on the opening side cannot fully open the hanging door e. However, there are drawbacks such as the appearance is not good.

[0010]

SUMMARY OF THE INVENTION In view of the above problems of the prior art, the present invention provides a substrate formed in a substantially L shape on the side surface, not only on the flat plate side but also on the standing plate side. Also, by rotatably supporting a freely rotatable guide roller, it is possible to guide both lower end surfaces of the hanging door without opening a window hole in the side pillar etc. The purpose is to enable smooth guide operation without fail, to ensure a smooth opening / closing operation for a long period of time, and to have a good appearance.

[0011]

In order to achieve the above-mentioned object, the present invention is attached to a corner portion between a base end portion of a side column and a floor surface which are erected on the closed end side of a hanging door. A roller type door guide for guiding a lower end of a traveling hanging door by rollers, wherein a substrate is a standing plate part attached to a side pillar from one side end of a flat plate part mounted and fixed on a floor surface. And is formed in a substantially L-shape on the side surface, and the first guide roller is rotatably supported by a vertically mounted roller bearing portion on the tip end side of the flat plate portion. A roller shaft vertically installed between the upper roller bearing plate and the lower roller bearing plate, which are attached to the upper side and the lower side in a separated state, has a peripheral surface running between the first guide roller. While supporting the second guide roller that rolls by contacting the lower end side surface of the hanging door,
It is an object of the present invention to provide a roller type door guide characterized in that the second guide roller is arranged between the upper roller bearing and the lower roller bearing plate and in a through hole formed in the standing plate portion. To do.

[0012]

[Operation] At the corner of the base of the side pillar standing on the closed end side of the hanging door and the floor, the board is placed on the floor and the standing plate is placed on the side pillar. It suffices to attach each of them by screwing, and it is not necessary to open and attach the window holes in the side columns. Next, the hanger roller fixed to the upper end of the door is engaged with the base rail to hang the door, and the lower end of the hanger roller is supported between the first and second guide rollers pivotally supported by the flat plate portion and the vertical plate portion, respectively. Insert it so that both sides of the lower edge of the door are sandwiched between the guide rollers.

The traveling of the hanging door causes the first and second guide rollers to rotate separately and guide both sides of the lower end of the door, so that the door can be comfortably traveled and a smooth opening / closing operation can be performed. can get. Further, since the second guide roller in the standing plate portion can be attached without being exposed to the opening side, the hanging door can be opened to the full opening portion, and the appearance is improved.
