[Industrial applications]

 The present invention attaches to the side pillars standing upright near the closed end of hanging doors, such as automatic doors, and the corners of the floor so that the door can be opened and closed. , The improvement of a roller type door guide used for guiding the lower end thereof.

[0002]

[Prior art]

 Conventionally, as a roller type door guide for a hanging door, those shown in FIGS. 4 and 5 (A) and 5 (B) are known. In this case, the substrate a is placed on the flat plate portion b. The standing plate portion c attached to the side pillar d is erected from the side end to form an L shape, and the distance from the other side end of the flat plate portion b to the standing plate portion b is adjustable. A roller support plate (not shown) is fixed to the roller shaft bearing rod (not shown) that is erected on the roller support plate. A guide roller f which is in contact with the end side surface e ′ and rolls is pivotally supported.

The roller type door guide is attached to a corner portion of a side pillar d and a floor surface g, and guides a lower end side surface e ′ of the hanging door e when the hanging door e is opened and closed by a guide roller f. At the same time, the undesired swinging of the suspension door e in the thickness direction is prevented. 5A and 5B, which are sectional views taken along the line BB ′ in FIG. 4, show the wind pressure from the side opposite to the guide roller, that is, the left side in FIGS. 5A and 5B. , The guide roller f is not always in contact with the guide roller f to open and close unless it is pressed by other force to make contact. In other words, not only the guide roller f is opened and closed while it is in contact with the guide roller f, but when it is not in contact with the guide roller f, it is also contacted with the sliding contact portion j of the standing plate portion c of the substrate a. It will open and close while swinging in the right or left direction.

Further, according to the positional relationship between the hanging door e and the hanger roller h, there are two types, a door eccentric hanging type shown in FIG. 5 (A) and a door center hanging type shown in FIG. 5 (B). The force F that pushes the door e against the standing plate c due to the runout is greater in the door eccentric suspension type than in the door center suspension type, and in the door eccentric suspension type, the center k of the suspension door e and the hanger roller are The value of F increases as the distance between the centers l of h increases. 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 type door guide becomes longer.

On the other hand, on the side of the lower end surface e ′ of the door that comes into contact with the guide roller f, smooth opening and closing movement can be obtained by the rotation of the guide roller f, but it is provided at the contact portion j of the standing plate portion c. Although the cushioning material m made of mohair, etc., certainly provides a sufficient cushioning effect against the swing of the suspension door e at the initial stage of mounting, as described above, in practice, the suspension door e moves to the left and right. Since it opens and closes while swinging, it wears relatively quickly and the sliding contact part j comes into direct contact with the door e.

Therefore, in order to prevent the hanging door e from being scratched even if the door directly contacts the sliding contact portion j, the sliding portion j is made of a synthetic resin material such as a material. However, abrasion powder of synthetic resin material due to sliding contact adheres to the hanging door e, and depending on the frequency of opening and closing, the synthetic resin material is completely consumed, and the standing plate portion that is generally made of metal. This causes contact between c and the hanging door e, resulting in generation of sliding noise and damage to the hanging door e itself, 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 in the center of the standing plate portion c of the substrate a and the through hole n At the opening edge, brackets o and p are bent in parallel from the upper part and the lower part, respectively, and guide rollers q are pivotally supported on the brackets o and p. A window hole r is opened in a wall or the like, and a guide roller and brackets o and p are provided in the window hole r so that the guide roller q projects from the standing plate portion c toward the guide roller f side. The size s 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 into a round hole or using a file to cut out into a square hole, and since it is difficult to do the work, considerable effort and labor must be applied.

Therefore, as shown in FIG. 7, two roller type door guides formed by separately supporting guide rollers f and q on separate substrates a and a ′ are prepared, and are provided on the side pillar d and the side surface of the wall, respectively. It is installed so as to be exposed to the opening side, or as shown in FIG. 8, guide rollers f and q are pivotally supported on the floor surface side of one substrate a and the side pillar d and the opening side of the wall, respectively. Although it may be considered that the structure is integrated so that the same function as in FIG. 7 is performed, in this case, the fully open state of the hanging door e cannot be obtained due to the guide roller q disposed on the opening side. Not only that, but it also has the drawback of not being visually attractive.

[0010]

[Problems to be solved by the device]

 In view of the above-mentioned problems of the above-described conventional technique, the present invention provides a substrate having a substantially L-shaped side surface, which is rotatable not only on the flat plate side but also on the standing plate side. By pivotally supporting the guide rollers, it is possible to guide both sides of the lower end of the hanging door without opening windows in the side pillars, so that the hanging door can be guided without difficulty. Its purpose is to ensure a smooth opening and closing operation over a period of time and to finish the appearance well.

[0011]

[Means for Solving the Problems]
