BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traveling device for suspending and traveling a door such as furniture and fittings.

[0002]

2. Description of the Related Art Due to the effective use of a room and the increase in storage capacity, stationary furniture for making a part of the room a clothes dance or a cupboard has come to be widely used. Since the fixed furniture has a large entrance and exit, if you use a so-called "double door" that uses two doors, one door will become large, and when you open the door you will not only hit objects around the fixed furniture, but also women and children. Is difficult to handle.

For this reason, recently, folding doors have become widely used, which can open the entrance widely without opening the door wide. The folding door is made by connecting multiple doors with hinges, and when the folding door is opened, the connecting portion is folded in an accordion style.

In the fixed furniture, a hanging rail is often laid on the upper sill and a guide rail is laid on the lower sill. In this folding door, a traveling device is installed in the upper part and a guide device is installed in the lower part.

The folding door installed in the stationary furniture has a portion that projects outward when opened and a portion that remains on the traveling rail of the Kamoi, and the traveling device is above the remaining portion. It is attached.

In the folding door, since a plurality of doors are suspended and the total weight is heavy, the Kamoi on which the traveling rails are laid may sometimes drop gradually over a long period of time. When the Kamoi goes down, the folding door that was hung by the Kamoi running rail also goes down, and the lower part of the folding door rubs against the guide rail, which makes it difficult to open or close the door at all.

When the folding door is lowered as described above, it is necessary to adjust the hanging portion of the traveling device to raise the folding door.
Moreover, the adjustment of the suspended portion is necessary not only when the door is lowered, but also when the door is attached to the stationary furniture. That is, when the folding door is attached to the stationary furniture, the position of the traveling device is not adjusted, so that the attachment position of the folding door may not be accurate at the time of attachment. Even in such a case, after the attachment, the suspension portion was adjusted.

In the conventional traveling device for hanging doors, the main body and the roller holder are connected by a male screw so that the hanging portion can be adjusted, and the folding door is moved up and down by rotating the male screw. It had a structure like this.

Here, a conventional traveling device for a hanging door will be briefly described. 4 and 5 are partially sectional front views of a conventional traveling device for a hanging door, and FIG. 5 is a side view of the same. The main body 1 has a cylindrical shape, and a hole 2 that does not penetrate is formed at the center of the cylindrical shape, and a fixing nut 3 is embedded in the upper portion of the main body 1. A male screw 4 is inserted into the hole while being screwed into a fixed nut 3, and a compression spring 5 for preventing loosening is installed below the male screw 4. A thin hexagonal engaging portion 6 is fixed to the male screw on the upper portion of the male screw 4, and a roller holder 7 is rotatably installed above the male screw. The roller holder 7 has a total of four rollers 8 in two pairs on both sides.
..., three rollers 9 are installed on the lower surface. Further, a groove 10 for preventing slipping out is formed in the lower portion of the main body 1.

This conventional traveling device for hanging doors travels while being suspended on a traveling rail R laid on a kamoi (dashed line in FIG. 5). The rollers 9 are located between the flanges of the traveling rail to prevent left and right blurring.

A conventional traveling device for a hanging door is attached to a folding door by attaching a circular shape substantially the same as that of the main body to the upper edge portion of the door (the two-dot chain line in FIG. 5) that remains on the side of the kamoi when the folding door is opened. Drill a hole and insert the body into the hole. Then, a retaining pin reaching the retaining groove 9 is inserted from the side surface of the folding door. When the traveling device for the hanging door is attached to the folding door in this way, the roller holder is inserted into the traveling rail laid in the Kamoi. At this time, if the folding door is not in the predetermined position, the hexagonal engaging portion 6 is rotated by a tool such as a wrench.
The hexagonal engaging portion 6 and the male screw 4 are fixed, and when the hexagonal engaging portion 6 is rotated, the male screw 4 moves up and down with respect to the fixed nut 3, so that the space between the main body 1 and the roller holding body 7 is increased. Spreads and narrows. In this way, the folding door is moved up and down to adjust the position.

[0012]

By the way, the conventional traveling device for a hanging door has a drawback that the space between the main body and the roller holder is naturally present during use and the folding door is lowered.
This is because rotation occurs between the roller holder and the main body when the folding door is opened and closed. That is, when the folding door is closed, the roller holder is parallel to the door, and when the folding door is opened, the roller holder travels while changing the angle with respect to the door.
Therefore, the roller holder always rotates with respect to the main body when the folding door is opened and closed, and with this rotation, the male screw screwed into the main body also rotates, resulting in a gap between the main body and the roller holder. It is something that will end up. Also, when opening and closing the folding door, the two doors that are connected are folded and returned, which causes severe vibration. In the conventional traveling device for a hanging door, the male screw may rotate due to this vibration.

In the conventional traveling device for hanging doors, the hexagonal engaging portion must be rotated when adjustment is performed, and a tool such as a wrench is required to rotate the hexagonal engaging portion. . Since the wrench has a thin hexagonal engaging portion and a narrow gap between the traveling rail and the folding door, a special wrench having a small thickness has to be used. Therefore, when adjusting the conventional traveling device for a hanging door, it was necessary to prepare a special wrench suitable for the hexagonal engaging portion and having a small thickness. Furthermore, the work of rotating the hexagonal engaging part with the wrench must be performed not only in a place where the folding door is difficult to see, but also while inserting the wrench in the upper part of the narrow folding door, engage the thin hex engaging part with the thin wrench. It had to be done, which was very troublesome.

According to the present invention, when the folding door is adjusted, a normal driver can be used without requiring any special tool, and the adjustment work can be performed from the side of the folding door, and the screw can be loosened even when the folding door is opened or closed or vibrated. It is to provide a traveling device for a hanging door that does not have the above.

[0012]

Means for Solving the Problems The present inventors have proposed that a pair of bevel gears can change the rotational movement by 90 degrees, and the male screw screwed into the female screw can be rotated by rotating the female screw. The female screw moves up and down, but even if you try to move the male screw that is screwed into the female screw that does not move, the male screw does not move up and down, and at this time, the female screw does not rotate. Completed the invention.

In the present invention, a vertical hole from the upper side and a horizontal hole from the horizontal direction are formed in a state of being orthogonal to each other; a female screw penetrating through the center is screwed, and the vertical hole of the main body is positionally immovable and rotatable. The transmission bevel gear installed on the main body; the drive bevel gear that is rotatably installed in the lateral hole of the main body and meshes in a direction orthogonal to the transmission bevel gear; It also consists of a male screw protruding upward from the main body; a roller holder rotatably attached to the upper end of the male screw and provided with a roller for traveling on a traveling rail laid in the Kamoi. It is a traveling device for hanging doors characterized by being provided.

The present invention is not limited to folding doors, but can also be applied to general furniture and fittings in which the door is hung from a duck or from above.

[0015]

[Function] Since the bevel gear is used to rotate the male screw for adjusting the distance between the main body and the roller holder, the male screw can be rotated from the direction easy to work. In addition, a female screw is screwed in the center of the bevel gear, and a male screw is screwed into the female screw.
A heavy male screw can be easily moved up and down without rotating the bevel gear with a large force.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. Figure 1
Is a partial front sectional view of the traveling device for a hanging door of the present invention, FIG. 2 is a side view of the same, and FIG.

A window 12 is formed in a body 11 having a substantially rectangular parallelepiped shape, and a vertical hole 13 is formed from above so as to reach the window 12.
Has been drilled. The upper portion of the vertical hole 13 is a square hole 14, and the step portion 15 is formed below.

A transmission bevel gear 16 is installed in the window 12 of the main body. The lower portion of the transmission bevel gear 16 has a groove 1 for receiving a load.
7, the groove contacts the stepped portion 15 of the main body and rotates. A penetrating female screw 18 is screwed at the center of the transmission bevel gear 16.

The female screw 18 of the transmission bevel gear 16 has a male screw 1
9 is screwed in. The male screw 19 protrudes above the main body 11 and is fixed to the rotation stopper 20 that easily moves up and down in the square hole 14 at the upper portion of the main body 11. A roller holder 7 is rotatably attached to the upper end of the male screw protruding above the rotation stopper 20. The rotation stopper may be fixed to the male screw or may be integrated with the male screw.

The roller holder 7 has two pairs of rollers 8 on both sides and three rollers 9 on the bottom.

A horizontal hole 21 is formed in the main body 11 from the side of the main body so as to reach the window 12. A drive bevel gear 22 is installed in the lateral hole such that the gear is located in the window 12. A positive driver fitting groove 23 is formed at the end of the driving bevel gear 22, and the driving bevel gear 22 can be rotated by inserting a plus driver through the lateral hole 21.

The drive bevel gear 22 meshes with the transmission bevel gear 16 at right angles, and when the drive bevel gear 22 is rotated, the force is transmitted to the transmission bevel gear 16 and transmitted.
Is designed to rotate.

As shown in FIG. 2, the main body 11 is provided with a retaining portion 24 whose lower portion bulges in a cylindrical shape. A screw insertion hole 25 is formed through the center of the column of the retaining portion.

Next, the mounting and adjustment of the sliding door traveling device of the present invention having the above structure will be described.

First, regarding the mounting of the hanging door traveling apparatus of the present invention, a notch having substantially the same shape as the side surface of the main body is formed on the upper side surface of the door (two-dot chain line in FIG. 2). The main body 11 of the traveling device for a hanging door of the present invention is inserted into the notch, and the screw hole 2
Insert a screw (not shown) from 5 and screw it into the door to fix it so that the main body does not come off. Next, the roller holder 7 is put in the running rail R of the Kamoi (two-dot chain line in FIG. 2) and the door is hung.

When the door is displaced from the predetermined position during the suspension, the door must be moved up and down to correct the position. This position adjustment is performed on the side surface of the main body inserted from the side surface of the door. That is, the lateral hole 2 formed on the side surface of the main body
Insert a Phillips screwdriver from 1 and apply the tip of the screwdriver to the screwdriver fitting groove 23 of the driving bevel gear 22 to rotate the screwdriver. Then, the driving bevel gear 22 is rotated by the rotation of the driver, the movement is transmitted to the transmitting bevel gear 16, and the transmitting bevel gear is rotated. The transmission bevel gear rotates in that position because the lower groove 17 is fitted in the stepped portion 15 of the main body so as not to come off in the vertical direction.

A female screw 18 is screwed in the center of the transmission bevel gear 16, and a male screw 19 is screwed into the female screw. Therefore, when the transmission bevel gear 16 rotates, the rotation is stopped by a rotation stopper. The male screw 19 comes to move up and down. Then, the roller holder 7 attached to the upper end of the male screw 19 also moves up and down, and the distance between the main body 11 and the roller holder 7 can be adjusted.

[0028]

As described above, in the hanging door traveling device of the present invention, the vertical movement of the door can be adjusted by a general driver without the need for a special tool, and the adjustment by the driver can be performed from the side of the door. Therefore, it is excellent in workability that a driver can be inserted and rotated very easily. Further, when the sliding door traveling device of the present invention is used for a folding door, the main body and the roller holding body rotate when the folding door is opened and closed, but the male screw penetrates the transmission bevel gear even when the male screw tries to rotate. Since the female screw is screwed and the male screw is screwed into the female screw, the male screw does not rotate, and there is no inconvenience that the main door and the roller holder are located and the folding door is lowered. It is also highly reliable.
