Description

[Detailed description of the invention] This invention relates to a door roller with a vertical adjustment mechanism, and the side adjustment position for adjusting the wheel position up and down can be easily adjusted up and down. This makes it easier to adapt to the adjustment hole in the section.

Various door rollers with vertical adjustment mechanisms have been proposed in the past, and the inventor of the present invention has already put them into practice.
54-105147. However, in the above 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 it will not move straight up or down. Friction occurs between the lifting piece and the lifting piece, making it difficult to adjust the screws from outside the case, making the adjustment work troublesome, and further improvements are desired.

Therefore, in this invention, we are trying to provide a door roller with a vertical adjustment mechanism that can eliminate the above-mentioned drawbacks.The structure is such that the door roller case has a vertical groove formed therein, and an inner case for holding the wheels is placed so that it can move freely in the lateral direction. A diagonal groove is formed in the inner case, a wheel pivot shaft is inserted into the vertical groove from the diagonal groove, and an adjustment screw A for moving the inner case in the lateral direction is provided. A door wheel whose pivot shaft can be adjusted up and down along a diagonal groove, the slider being engaged with the inner case so as to be able to move up and down while maintaining the adjustment screw A horizontally. A screw B is provided to adjust the elevating member that holds the adjustment screw A from below in a direction perpendicular to the screw A, and by adjusting the screw B, the adjustment position of the screw A can be adjusted up and down. It is characterized by the fact that

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

10 is a door roller case, 11 is a vertical groove formed in the door roller case 10, 20 is an inner case for holding wheels that is equipped to be able to move freely laterally (horizontally) within the door roller case 10, and 21 is an inner case for holding the wheels. This is a diagonal groove formed in the inner case 20, and the pivot shaft 31 of the wheel 30 is fitted into the vertical groove 11 from the diagonal groove 21.

A is a screw, which is inserted into the U-shaped groove 22 of the inner case 20.
The slider 23 is fitted into the inner case 20 and is engaged with the side surface of the inner case 20 and is capable of only vertical movement.
0 in the lateral direction and vertically adjust the pivot shaft 31 in the vertical groove 11 along the diagonal groove 21.
The position can be adjusted up and down. The shaft portion of the screw A near the head is fitted into a U-shaped groove 12 formed on the side of the door roller case 10, so that the head is exposed to the outside. Reference numeral 13 denotes a member for raising and lowering the screw A, and a bent portion 14 of the member holds the screw A.

Next, B is a screw that is adjusted from below in a direction perpendicular to the screw A, 15 is an adjustment part for screw B that is opened on the bottom surface of the door roller case 10, and 16 is a member that prevents screw B from moving. be. By adjusting the screw B, the position of the screw A itself is adjusted up and down, so that the working position for adjusting the wheel 30 up and down can be adjusted using the screw A.

In addition, regarding the actual screw A, it is implemented such that only the head of the screw A is always kept exposed to the outside of the door roller case 10, that is, the inner case 20 is moved laterally, but the screw A itself is moved back and forth. There are two types of mounting methods: one is to install it in such a way that it does not move (see Figures 1 to 6), and the other is to install it so that the screw A itself moves forward and backward (see Figures 7 to 9).
The latter implementation is preferable if the space is such that there is a risk that the screw A may enter the inner case 20 too far and come into contact with the wheel 30 or the like.

In the figure, 17 is a protrusion formed on the door roller case 10 that prevents the inner case 20 from being pulled out upward;
Reference numeral 8 indicates a mounting portion, and reference numeral a indicates an adjustment hole for a screw A formed in the side surface of the sliding door C.

Further, the shape of the outer door roller case 10 can be variously implemented, and the screws A and B also include threaded bolts, etc., and any shape suitable for practical use may be used. Furthermore, door car case 1
It is also possible to install a spring-like hanging plate 40 on the outside of the 0.It is also possible to carry out the installation by attaching a spring-like hanging plate 40 to the outside of the frame. (see Fig. 13), and there are also full-width ones (see Fig. 13) that are common to the front and rear, and all have a hooking part 41 and a hooking protrusion 42 at the lower end for hooking onto the lower stile C'.

This device is constructed as described above and is used as a door roller for sliding doors C and other doors.For vertical adjustment during use, first, use the screws drilled in the side of sliding doors C. Adjustment hole a for A
Adjust the elevating member 13 vertically using a screw B from below in a direction perpendicular to the screw A so that the screw A in this invented configuration fits in the position shown in FIG.

Then, move the inner case 20 using the screw A at a position that matches the adjustment hole a, and adjust the pivot shaft 31 of the wheel 30 up and down within the vertical groove 11 of the door roller case 10 using the diagonal groove 21. Thus, the position of the wheel 30 can be adjusted.

That is, when the inner case 20 is pushed to the left in the figure with the screw A, the position of the wheel 30 moves downward, and when the screw A is returned and the inner case 20 is moved to the right, the position of the wheel 30 moves upward. Because it can be moved,
The wheels 30 can be easily adjusted to match the rails.

As described above, the position of the wheel 30 can be adjusted up and down, but in the case of a ready-made sliding door C, etc., the position of the adjustment hole a, which is usually opened on the side surface, is determined by the manufacturer. Since there are many cases where the screws are not fixed, if the screw A is set at a fixed position, it will not fit with the adjustment hole a.
In this invention, as mentioned above, the lifting member 1 is
By adjusting 3 up and down, the fitting position of screw A can be easily adjusted.

In particular, since the screw A is screwed into the slider 23 engaged with the inner case 20 so that it can move up and down while maintaining the horizontal position, and the inner case 20 can be moved laterally, the elevating member 1
Even if the wheel 3 is adjusted by moving up and down, the horizontal direction can be maintained constantly. Therefore, the screw B, which is adjusted from below in the perpendicular direction, can be reliably connected to the screw A through the lifting member 13, and the wheel 30 is There is no fear that the screw A will tilt even when adjusted up or down, and it is extremely easy to perform adjustment from the outside.

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