Abstract

PROBLEM TO BE SOLVED: To enable a sliding door to travel exceptionally smoothly with a minimum resistance by fitting a long, slender cylinder-shaped guide provided on the lower end of a rail into a grooved-shaped insertion area formed on the top of a slider. SOLUTION: A cross section-inverted key hole-shaped rail 3 provided with a long and slender cylinder-shaped guide 11 on the lower end is mounted on the lower end face 3 of a head jamb 1. Then, a slider 8 formed with a groove- shaped insertion area 5 on the top is mounted on the top 7 of a sliding door 6. The insertion area 5 of the slider 8 is fitted in the guide 11 so that it may move sliding along the rail 3. Therefore, the slider 8 and the rail 3 are placed in line contact with each other, thereby reducing the resistance of the sliding door and enabling the sliding door to run smoothly. In addition to that, it is better that the slider main body of the slider is formed separately from the insertion ares while the insertion area is adjustable to the main body so that it may be positioned in the crosswise direction of the main body.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rail which is attached to a dwell for standing a sliding door and a slider which is attached to a top surface of the sliding door and is fitted with the rail so that the sliding door can be smoothly opened and closed. The present invention relates to a guide device in the upper part of a sliding door which is a combination of

[0002]

2. Description of the Related Art As is well known, in the upper part of a conventional sliding door, a convex portion projectingly formed on the top surface is fitted in a groove formed on the lower end surface of the kamoi, and the convex portion is formed when the sliding door is opened and closed. It is guided by sliding in the groove of the Kamoi.

[0003]

However, since the contact area between the convex portion of the top surface of the sliding door and the groove portion of the Kamoi is large, there is a problem that the sliding door cannot be opened and closed smoothly due to a large resistance. There is.

Generally, a door roller is generally attached to the bottom surface of the sliding door so that the door can be smoothly opened and closed.
In particular, there is used a door roller that can be easily erected in good condition by adjusting the position of the vehicle in the thickness direction of the sliding door.

However, even if the position of the door roller attached to the bottom surface of the sliding door can be adjusted in the thickness direction, it cannot be adjusted in the thickness direction above. Therefore, if only the lower end is adjusted to the position in the thickness direction, the sliding door is adjusted. There is also a problem that the whole tilts and smooth opening and closing cannot be performed.

[0006]

In order to solve the above-mentioned problems, according to the present invention, the guide can be slid with a rail which is attached to a duck having a reverse cylindrical keyhole shape and which has a slender cylindrical guide at its lower end. And a slider attached to the top surface of the sliding door formed on the top surface.

Further, in addition to the above-mentioned means, it is more preferable that the slider is separately provided in the insertion portion and the slider body, and the insertion portion can be adjusted in the width direction with respect to the slider body.

And the main body 52 is pressure-bonded to the back surface of the end wall 37.

Then, a tool such as a screwdriver is inserted into the locking groove 56, the operation portion 35 is pushed into the chamber 51 against the spring force of the spring 54, and is rotated in either the left or right direction. Is rotated to move the shaft 53 in the engagement hole 50 to slide the fitting member 33 in the width direction. That is,
By pushing a tool such as a driver into the operation piece 35 and turning the operation piece 35, the insertion portion 25 is slid in the width direction of the slider body 32 by the operation of the cam 34, and the insertion portion 25 is adjusted in the width direction. Of.

In this embodiment, the shaft 53 of the cam 34 is used.
Is located below the main body 52 and engages with an engagement hole 50 formed below the support rod 46. Therefore, the operation piece 3
When viewed from the side of 5, the insertion member 25 slides to the left when the operation piece is pushed and turned to the right, and the insertion member 25 slides to the right when turned to the left.

When the pressing force applied to the operating portion piece 35 is released when the fitting member 25 is adjusted to an appropriate position, the cam 34 and the operating portion piece 35 return to their original positions by the urging force of the spring 54. The locking projection 55 of the operation portion piece 35 and the locking portion 48 of the fitting insertion hole 47 are fitted to each other, and the cam 34 is fixed at a predetermined position.

In particular, in this embodiment, in order to make the position adjustment in the thickness direction easy to understand, the surface 60 of the end wall 37 provided with the operating body 35 is provided with push and turn indications 60 for right and left. ing.

It is embedded in the concave fitting portion 59 formed at the corner 58 with the wood opening surface 57, and at this time, the top surface 24 of the fitting insertion portion 25 is flush with the top surface 27 of the sliding door 26.
The end wall 3 of the slider body 32 on the side provided with the operation portion 35
7 is attached on the same surface as the side of the mouth 57, the center of the slider 28 in the width direction and the center of the sliding door 26 in the thickness direction are aligned, and is fixed to the bottom wall 39 with the fixing screw 70.

As described above, the slider 2 is used in this embodiment.
As shown in FIG. 4, the sliding door 26 on which the rail 8 is attached to the rail 2 is attached to the fitting insertion portion 25 of the slider 28 as in the above-described embodiment.
The guide portion 31 of No. 3 is fitted and stood upright, and the guide portion 31 and the fitting insertion portion 25 are slidably fitted together, and a smooth opening / closing operation can be performed as in the above-described embodiment.

The end wall 3 with the sliding door 26 standing upright
7, the operating portion piece 35 is pushed to release the fitting state of the operating portion piece 35 with the fitting insertion hole 47, and the operating portion piece 35 is rotated in that state to move the fitting insertion portion 25 in the width direction. As a result, the mounting position of the sliding door 26 on the slider 28 in the thickness direction can be adjusted. FIG.
8 shows a state in which the fitting insertion portion 25 of the fitting member 33 is located at the center, and in FIG. Yes, and FIG. 9 shows a state of being moved to the right.

In this embodiment configured as described above, since the guide portion 31 makes substantially line contact with both end surfaces 68, 68 of the fitting insertion portion 25, there is little resistance when opening and closing the sliding door 26, and running is extremely smooth. In addition to the effect of being able to obtain, it is possible to adjust and fit the fitting insertion portion 25 in which the guide portion 31 is fitted in the thickness direction of the sliding door 26 by turning the operation portion piece 35. It will be.

In the present embodiment, the operation piece 35 has a gear-shaped locking projection 55 formed on the peripheral surface thereof, and is engaged with the gear-shaped locking portion 48 of the operation hole 47 so as to be engaged therewith. Thus, a secure and stable fitting state is obtained, which produces an effect of fixing the position of the cam 34, but the present invention is not limited to this configuration.

For example, as shown in FIG. 10, the operating portion 61 is formed in a substantially truncated cone shape, and the wide surface is the inner surface of the end wall 37 and the narrow surface is the surface of the end wall 37. Other structures such as a structure in which the structure is exposed and fitted to the end wall 37 may be used.

Further, in the present embodiment, the cam 34 and the support rod 46 are used for sliding the fitting / inserting portion 25 in the width direction, but the present invention is not limited to this structure, and the fitting / inserting portion is not limited thereto. Any means can be adopted as long as the portion 25 can slide in the width direction with respect to the slider body 32.
