固定機構に関する。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a door roller fixing mechanism, and more particularly to a door roller fixing mechanism attached to a sliding door type fitting such as a sliding door sash.
＜従来技術と、考案が解決しようとする課題＞ 従来より、戸車の引戸サッシ等への取付けにおいては、

号公報参照）。<Prior Art and Problems to be Solved by the Invention> Conventionally, when attaching a door roller to a sliding door sash or the like,
Using a spring plate-shaped mounting frame instead of troublesome screwing,
A mounting mechanism is known in which a door roller can be elastically fitted and fixed in a mounting hole provided in a lower frame. In such a door roller mounting mechanism, the door wheels are set at a predetermined height position by hooking the lower ends of both side plates of the mounting frame to the lower ends of the lower frames, while the cut-and-raised locking pieces formed on the both side plates are mounted on the door frame. By being pressed against the inner surface of the side wall of the hole, it is provided so as to prevent the movement of the door roller in the traveling direction (for example, Japanese Utility Model Publication No. 51-9791).
(See the official gazette).

ッシ等の荷重が大きすぎたり、激しい開閉動作が繰り返
されたりすると、バネ板からなる上記両側板の下端が下
框の下端から外れ、戸車が下框内に埋没してしまうとい
う不都合がある。However, in the attachment mechanism of the door roller, when the load of the sliding door sash or the like is too large or when the violent opening / closing operation is repeated, the lower ends of the both side plates made of the spring plates are disengaged from the lower end of the lower frame, and the door roller is moved to the lower frame. There is the inconvenience of being buried inside.

が生じる。On the other hand, a screw member capable of adjusting the height of the installation position of the door roller is projected above the door roller case, the upper end of the screw member is brought into contact with the upper surface of the mounting hole, and the screw member is rotated to rotate the door roller. There is provided a door roller whose height position can be adjusted (see Japanese Utility Model Laid-Open No. 55-74371). Therefore, it is conceivable to use this screw member as a fixing member for the door roller to prevent the door roller from being buried in the lower frame of the door roller. However, in this case, the screw member only comes into contact with the upper surface of the mounting hole. Therefore, there is a problem in that the door roller is sloping left and right in the traveling direction, and the sliding door sash or the like cannot be opened and closed smoothly.

目的とする。This invention has been made in view of the above problems, and in addition to preventing the door car from being buried in the lower frame of the door car, it eliminates the left and right grabs in the running direction of the door car so that the fittings can be opened and closed smoothly. It is an object of the present invention to provide a fixing mechanism for a door roller.

点もある。As shown in FIG. 4, the pair of expansion pieces (11) (11) are formed symmetrically with respect to the shaft hole (17) which is inserted through the support shaft (10). May be That is, as a modified example, both lower end portions (1
Both 1d) and (11d) are tapered and are formed so as to gradually curve in the one rotation direction, and like the above rotation tip portions (11b) and (11b) as the upper end portion, a pair of expansion pieces are formed. (11) (11) is provided so as to be able to face the mutually opposite outer sides in a state where it is pivotally attached to the support shaft (10). In this case, the lower end portions (11d) (11d) of both of the above can be integrally rotated with the rotating front end portions (11b) (11b), and also at the lower end portions (11d) (11d),
The side walls (13) and (13) can be brought into contact with the lower portion of the door roller accommodating portion (D), and the space between the side walls (13) and (13) can be fully expanded. At this time, a pair of expansion pieces (11) (11) shown in FIG.
Expands into a substantially X shape in the door car housing (D), and the door car (A)
It functions as a bruise. According to this, not only the pair of expansion pieces (11) (11) can cope with the load applied to the door roller (A) from above and sideward, but also the door roller accommodating portion (D).
It is possible to cope with the load from the lower side of the door, and in cooperation with the hooking piece (15), the door roller (A) can be more firmly fixed and supported. Moreover, this lower end (11d) (11
If d) is provided so that it can be engaged with the stepped portion (16) of the door roller accommodating portion (D), even if the spring-like hanging plate (14) is omitted,
There is also an advantage that (A) can be attached to the door roller accommodating portion (D).

Therefore, slits (19) extending vertically from the upper end to the lower end are formed at the positions corresponding to the respective expansion pieces (11) on the left and right side portions (1c) (1c) of the outer frame (1). The pair of expansion pieces (11) (11) are provided so as not to hinder the expansion. In this example, the expansion piece
Compared to the expanding piece (11) of the above embodiment, (11) is formed substantially straight from the base end (11a) to the rotating tip (11b) without being curved, and the tip is formed to be round. The difference is that. However, a pair of expansion pieces in this embodiment
(11) As (11), since it is previously expanded and set in a substantially V shape, the relative load from the upper surface (12) is received by the inclining expansion piece (11) itself. be able to. Therefore, also by this, the pair of expansion pieces (11) and (11) can be rotationally displaced to the outer sides opposite to each other, and can be easily expanded to the outer side, and function similarly to the above. be able to.

Of the wheel holding member (20), which is inserted through the bottom portion (1a) of the wheel holding member (20) and is capable of vertically adjusting the wheel (3) pivot side of the wheel holding member (20). And a structure consisting of A nut (23) that can be screwed into the screw member (22) is attached to an end side position of the wheel holding member (20) corresponding to the screw member (22). That is, the screw member (2
By turning 2), the nut (23) that is screwed into this can be moved up and down, and the wheel support member (20) is rotated at a predetermined angle with the horizontally installed support shaft (21) as the center of rotation. It can be rotated (see arrow in the figure).

とができる。<Effects of the Invention> As described above, according to the fixing structure of the door roller of the present invention, by pushing up the pair of expansion pieces, both the expansion pieces are kept along the upper surface of the door roller accommodating portion. Since it can be expanded to the full extent between both side walls and can be used as a so-called bruise of a door roller in the door roller housing part, this pair of expansion pieces must support the load from above or to the door roller. Therefore, the door roller can be fixedly supported at the center position between the both side walls. Therefore, it is possible not only to prevent the door car from being buried in the lower frame, but also to eliminate the left and right shading in the running direction of the door car and to ensure the smooth opening and closing of the fitting.
また、一対の拡開片を上記のように拡開させるだけで、
戸車を戸車収容部の中心位置に固定できるので、戸車収
容部の幅寸法に多少の違いがあっても、融通性良く固定
することができる。Also, just by expanding a pair of expansion pieces as described above,
Since the door roller can be fixed to the center position of the door roller housing portion, even if there is a slight difference in the width dimension of the door roller housing portion, the door roller can be fixed with good flexibility.
更に、一対の拡開片を戸車収容部の両側壁間一杯に拡開

る。Further, when the pair of expansion pieces are fully expanded between both side walls of the door roller accommodating portion, both pivoting tip portions are pressed against the both side walls to prevent the door roller from being displaced in the traveling direction. That is, various practicable effects peculiar to the above can be achieved.
