Abstract

(57) [Summary] [Structure] Of the door roller, the L-shaped stop angle 5 having the vertical portion 51 with the hole 50 and the horizontal portion 52 for connecting the frame is formed on the both sides 20 of the holding portion 2 for the wheel by combining them horizontally. The mounting position can be adjusted by vertically inverting the position of the portion 52. [Effect] Even if the lower frame A is a one-step rib type or a two-step rib type, it is possible to cope with it by reversing the position of the horizontal portion 52 of the L-shaped stop angle by 180 °. It can be attached directly to the rib of the lower frame with screws and has excellent stability.

[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door roller, and more particularly to a door roller capable of adjusting a mounting position on a lower frame.

[0002]

[Problems to be solved by conventional techniques and devices]

 Many conventional door rollers have a structure in which the position of the wheel at the mounting position is raised or lowered, and the structure can be adjusted by a so-called up-down adjustment mechanism. Due to the space inside the lower frame, it may be difficult to install the door roller. More specifically, there are cases where the lower frame space has sufficient depth and cases where the lower ribs for reinforcement are formed in the middle to limit the depth. If the screw connection is in a fixed position, there will be no flexibility.

Therefore, it has been proposed to use a spring plate-shaped mounting frame without using screws (for example, Japanese Utility Model Publication No. 61-16368), but it was more unstable than screw fixing. Therefore, in the present invention, it is an object of the present invention to provide a door roller with an adjustable mounting position, in which the door roller is connected to the lower frame by a screw connection and the mounting position to be connected can be selected up and down. There is.

[0004]

[Means for Solving the Problems]

 A door roller according to the present invention, which solves the conventional problems as described above and achieves the object, has an L-shaped vertical portion with a hole and a horizontal portion for frame connection which can be screwed to both sides of a holding portion for a wheel. A combination of letter-shaped stop angles is characterized in that the position of the horizontal part for connecting the frame can be selected either up or down by reversing the position.

[0005]

[Action]

 According to the door roller of the present invention having the above-described structure, the L-shaped stop angle having the vertical portion with the hole that can be screwed to both sides of the holding portion of the door roller and the horizontal portion for connecting the frame is combined so that the position can be inverted. It is possible to attach the stop angles to both sides of the door holding portion by selecting the position of the horizontal portion for connecting the frame to either upper or lower.

Therefore, when there is a depth in the inner space of the lower frame, the horizontal part for frame connection should be up, and when there is a lower reinforcing rib in the middle of the lower frame, the frame connection should be made to match the position of the reinforcing rib. If the L-shaped stop angle is turned upside down so that the horizontal portion of the door is down and the door roller is attached to the lower frame, the installation can be done to match the space of the lower frame.

【Example】

 Next, embodiments of the present invention will be illustrated below with reference to the drawings. Reference numeral 1 denotes a wheel, which has two wheels in the illustrated case. Reference numeral 2 is a holding portion for the wheel 1 and supports the wheel 1 as a shaft. Reference numeral 3 denotes a spring plate-shaped mounting frame. Reference numeral 4 denotes a plurality of adjusting screw holes formed on both side portions 20 of the holding portion 2 and having different height positions. Reference numeral 5 is an L-shaped stop angle having a vertical portion 51 with a plurality of stages of holes 50 which are screwed at any position of the screw hole 4, and a horizontal frame 52 for connecting a frame. Form a long hole 53. As is apparent from the perspective views of FIGS. 1 and 2, the stopper angle 5 is formed separately from the holding portion 2 so that the horizontal portion 52 can be inverted by 180 ° so that the horizontal portion 52 is turned upside down. There is. The stop angle 5 preferably has a shape capable of holding a part of the holding portion 2.

When the horizontal portion 52 is combined so as to be on the upper side as shown in FIG. 1, the horizontal portion 52 of the stop angle 5 is attached to the rib a of the lower frame A of the one-step rib type as shown in FIG. Should be stopped with screw b ₁ . Regarding the position adjustment of the holding portion 2 on the door roller main body side with respect to the horizontal portion 52, the screws b are formed by the plurality of holes 50 of the vertical portion 51 of the stop angle 5 and the plurality of holes 4 provided on both side portions 20 of the holding portion 2. Up and down adjustment can be performed by selecting the stop position of ₂ .

Further, in the case where the horizontal portion 52 of the stop angle 5 is combined to the lower side as shown in FIG. 2, the lower frame A, which is a two-step rib type, has the upper rib a and the lower rib a ′. the have, 'suitable if you have formed a door roller housing opening opened a portion of the horizontal portion 52 rib a angle 5 stop 4' ribs a bis b ₁ to If the fixed position is selected by the plurality of holes 50 of the vertical portion 51 and the plurality of holes 4 on both side portions 20 of the holding portion 2, the vertical position can be adjusted.

In any of the above cases, the hole 50 of the vertical portion 51 is not only an independent hole but also a long hole 50 'which is continuously spliced in consideration of the screw diameter as shown in FIG. Even if it is formed, it is convenient to select a multi-stage fixing position, and in addition to this, the long hole of the horizontal portion 52 can be implemented with the same purpose. In the figure, 31 is a spring tip of the spring plate-shaped mounting frame 3, 32 is an auxiliary spring plate added by cutting and raising within the range of the mounting frame 3, both of which come into contact with the inner wall surface of the lower frame A. The spring tip may be bent outward so that it can be locked to the lower end of the lower frame A.

The structure of the present invention can be applied to a door roller that does not have a spring plate-shaped mounting frame. Of course, the number of wheels of the door roller is not limited to a plurality of wheels, but it can be applied to a single wheel, and it goes without saying that the vertical position of the wheels can be adjusted by adopting various known mechanisms.

[0012]

[Effect of the device]

 According to the present invention, as described above, since the stop angle is combined with the holding part of the door roller so that the horizontal part of the L-shaped stop angle can be vertically displaced 180 °, the inner shape of the lower frame is a one-step rib type. It is possible to support both the two-stage rib type and the two-stage rib type, and in any case, the horizontal part can be fixed to the rib with screws and can be stably attached. It loses stability and has excellent stability in use.
