Description

[Detailed explanation of the invention] This invention is a door roller with a vertical adjustment plate structure that allows the side adjustment position for adjusting the opening wheel position up and down to be easily adjusted up and down. This makes it easy to adapt to the adjustment hole in the side part, and at the same time allows the wheel to be adjusted up and down from either the side part or the lower part.

Various door rollers with vertical adjustment plate structures have been proposed in the past, and the inventor of the present invention has already proposed the
47 has been proposed.

However, in the above-mentioned application, the screw that is adjusted from the side is screwed into the horizontal support shaft, so if the position of the horizontal support shaft changes while tilting up and down, the screw may tilt diagonally, and instead of straight up and down. Friction occurs between the lifting piece and the
It was difficult to adjust the screws from outside the case, and the adjustment work was troublesome, so further improvements were desired.

Moreover, the threaded bolt at the bottom only has the function of raising and lowering the elevating piece, and the wheel can only be adjusted up and down with the screws on the side, so due to the structural limitations of the sash, it is not possible to adjust the wheel up and down from the side. If this is difficult, the above adjustment mechanism cannot be used, and in such cases, it has been desired to be able to adjust the wheels up and down from below.

Therefore, in this invention, we are trying to provide a door wheel with a vertical adjustment plate structure that can eliminate the above-mentioned drawbacks.The structure is such that a part of the holding member that pivotally supports the wheel is pivotally supported at a predetermined position of the case, and the door wheel is held at a predetermined position. The side part of the member is shaped as an inclined surface, and a screw A that contacts the inclined surface and adjusts the wheel pivot side of the holding member up and down is inserted from the side side of the case. A feature is that a screw B is provided for adjusting the member from below in a direction perpendicular to the screw A, and the position of the screw A can be moved up and down by adjusting the screw B.

Next, embodiments of this invention will be illustrated below with reference to the drawings.

1 is a door roller case, 2 is a holding member that pivots 4 on wheels 3,
A portion of the holding member 2 is pivotally supported 5 at a predetermined position in the lower part of the case, and a lateral side portion connecting the front and rear surfaces of the holding member 2 forms an inclined surface 6.

A is a screw, the tip of which is in contact with the above-mentioned inclined surface 6, and the holding member 2 is
The wheel pivot side of the screw is vertically adjusted, and the screw head side is exposed to the outside of the case from a long through hole 7 provided on the side of the case 1.

A part of the screw A is held by a bent portion 8' of the lifting member 8, and the lifting member 8 can be moved up and down by a screw B adjusted from below in a direction perpendicular to the screw A. ing.

9 is an adjustment part for screw B drilled on the bottom surface of case 1;
10 is a member for preventing the screw B from moving.

Note that the lateral side of the case 1 has two folded pieces 11 and 11 extending to the sides of the case body in a substantially U-shape.
It is preferable that the folded pieces 11 and 11 are pressed together to form a piece with a through hole 7, which has the advantage of being easily shaped by press working or the like.

Further, the above-mentioned screws A and H include threaded bolts and the like, and any shape suitable for practical use may be used.

This device is constructed as described above, and is used as a door wheel for the sliding door 20 and other doors.In order to make it easier to adjust the height during use, holes are usually first drilled in the side of the sliding door 20. The elevating member 8 is adjusted vertically using a screw B from below in a direction perpendicular to the screw A so that the screw A of this invented structure fits in the position of the adjustment hole 21 for the screw A.

Then, by holding the screw A at a position that coincides with the adjustment hole 21 and adjusting the degree of contact with the lateral inclined surface 6 of the holding member 2 of the wheel 3, the holding member 2 is moved around the shaft support 5 portion. The position of the wheel 3 can be adjusted by rotating the wheel pivot side up and down.

That is, if the screw A is pushed forward at the same position, the wheel 3 will move downward, and if the screw A is returned, the wheel 3 will move upward, so that it can easily match the rail L.

As described above, the position of the wheel 3 can be adjusted up and down, but the position of the adjustment hole 21, which is usually opened on the side surface of a ready-made sliding door 20, is fixed depending on the manufacturer. In many cases, screws A are not fixed at a predetermined position, so that they do not fit with the adjustment holes 21. However, in this invention, as described above, the lifting member 8 can be adjusted up and down using screws B. By doing this, the fitting position of screw A can be easily adjusted.

In particular, since the screw A is only in contact with the inclined surface 6 of the holding member 2, even if the elevating member 8 is moved up and down and adjusted, the horizontal direction can be constantly maintained. The screw B, which is adjusted from below, can be reliably connected and operated via the elevating member 8, and there is no fear that the screw A will tilt even when the wheel 3 is adjusted up or down, and it is extremely easy to adjust from the outside. It turns out.

Furthermore, even if the vertical adjustment of the wheel cannot be performed using screw A, that is, if the structure of the sliding door does not have an adjustment hole on the side surface, or if it is difficult to operate the screw from the side. By operating the lower screw B, the wheels can be adjusted up and down to some extent.

That is, when the lifting member 8 and the screw A are moved up and down by operating the screw B, the tip of the screw A is in contact with the inclined surface 6 of the holding member 2. When pushed, the same effect as directly operating the screw A is performed, and the rotation of the holding member 2, that is, the vertical position of the wheel 3 can be adjusted.

Therefore, the vertical adjustment of the wheel 3 can be sufficiently performed not only from the side but also from below, resulting in extremely high operational flexibility.

Therefore, the attachment adjustment of the door roller to the sliding door etc. becomes reliable and efficient, and the practicality is improved.
