DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention corrects sinking near the center of a door roller by height adjustment due to wear of the door roller or deformation of a groove bottom wall of a floor surface on which the door roller is laid. In door rails that can be
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door stroller rail that can prevent noise from being generated when a door stroller wheel rolls on a rail when a rail body floats.

[0002]

2. Description of the Related Art As a conventional rail for this type of door stroller, there is one described as "combination structure of door wheel and wheel" described in Japanese Patent Application Publication No. 243280/1995.

According to the present invention, a screw portion is provided at the center or near the center of the rail main body in order to correct the sink near the center of the rail main body inserted in the rail cover. The height of the rail body was adjusted by adjusting screws to be screwed.

[0004]

In this door rail, an adjusting screw is provided at the center or near the center of the rail body, but the rail body is fixed at both ends with wood screws or the like. Therefore, there is a problem in that the rail body moves up and down due to vibration when the door wheel rolls on the rail, and noise is generated.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide a rail for a door stroller which does not generate noise even if the wheel of the door stall rolls on the rail by fixing the rail body with a wood screw or the like. Things.

[0006]

SUMMARY OF THE INVENTION A rail for a door car according to the present invention comprises:
A door rolling groove is formed on the upper surface and a groove is formed on both sides.
The main body and the rail main body are inserted and
The flange that extends in the direction is formed, inside the pieces on both sides
Consists of a rail cover with a ridge with a semicircular cross section formed in the longitudinal direction, and an adjusting screw for adjusting the height of a part near the center of the rail main body is provided on the bottom wall of the door roller rolling groove of the rail main body. A rail for a door roller screwed to a formed screw hole or a nut attached to a bottom wall of a door roller rolling groove, and fixed to a flooring material together with a rail cover at a location other than both ends of the rail body with a wood screw or the like. It is characterized by the following.

[0007]

Since the rail body is fixed to the flooring material with wood screws or the like, even if the door wheel rolls on the rail, it does not vibrate and no noise is generated.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a rail for a door car according to the present invention. FIG. 1 is a cross-sectional view of a rail body constituting a rail for a door stroller of the present invention, FIG. 2 is a cross-sectional view of a rail cover also forming a rail for a door stroller of the present invention, and FIG. FIG. 4 is a vertical sectional side view taken along line AA of FIG. 3, and FIG.
FIG. 4 is an enlarged sectional view taken along line BB of FIG. 3.

Reference numeral 1 denotes a rail body constituting a rail for a door roller according to the present invention, which has a door roller rolling groove 11 formed on an upper surface thereof, and a bottom wall 1 of the door roller rolling groove 11 substantially at the center of the rail body 1.
2, a screw hole 13 into which an adjustment screw to be described later can be screwed is formed, a step portion is formed between the door wheel rolling groove 11 and the bottom wall 12, and a wheel of the door wheel rolling on the door wheel rolling groove 11. A bulged portion R1 formed at the center of the outer periphery of R is fitted so that the wheel R does not come off the rail main body 1.

On both sides of the rail body 1, grooves 14,
The raised position of the rail main body 1 is restricted by a protrusion of a rail cover described later.

Reference numeral 2 denotes a U-shaped channel-shaped rail cover constituting the rail for a door car according to the present invention, wherein flanges 21 and 21 extending outward are formed at the upper ends of both side pieces.
Further, ridges 22, 22 having a semicircular cross section are formed in the longitudinal direction on the inner side of both side pieces.

Numeral 3 is an adjusting screw for adjusting the height of the rail body 1, which has a hexagonal hole at the upper end of which a hexagonal wrench can be fitted, a plus groove for fitting a screwdriver tip, and the like. There is no straight screw.

Reference numerals 4 and 4 denote sweeping-out tools attached to both ends of the rail body 1, which are integrally fixed together with the door rail with wood screws 5 when the door rail is laid.

Next, the method of laying the rail for a door car according to the present invention will be described. First, a rail body cut into required dimensions and having a screw hole 13 and a wood screw insertion hole 14 formed in a bottom wall 12 at a substantially central portion. 1 is inserted from the end face of the rail cover 2 cut to the required dimensions in the same manner as the rail main body into the grooves 14, 1,
Prepare what has been inserted so that 4 can be inserted.

Next, the rail cover 2 on which the rail body 1 is mounted is fitted into a groove formed in advance in a place where the rail of the flooring material F such as a floor or a sill is laid. At each end,
After being fixed to the bottom wall of the groove of the flooring material F together with the spout 4 with the wood screw 5, the wood screw 6 is inserted into the wood screw insertion hole 14 formed in the rail body 1, and penetrates the bottom plate of the rail cover 2. The work is completed by fixing the flooring material F to the bottom wall of the groove.

At the beginning of the laying of the rail for a door car, there is no sinking near the center of the rail body 1, but when the sliding door is opened and closed for a long time and sinks near the center, the wood screw 6 is first removed. If the adjustment screw 3 is screwed down with a tool such as a hexagon wrench or screwdriver, the adjustment screw 3 will not go down any further. The screw portion of the screw hole 13, that is, the rail body 1 is pushed up and the rail body 1
To keep the rail body 1 horizontal.

By continuing to turn the adjusting screw 3, the rail body 1 is raised and the step 14 below the grooves 14, 14 as shown in FIG.
When the rails a and 14a come into contact with the ridges 22 and 22 of the rail cover 2, the rail body 1 cannot be lifted any more, and
Is not turned, so that the adjusting screw 3 does not come off from the screw portion of the screw hole 13.

After the height adjustment of the rail main body 1 by the adjustment screw 3 is completed, the wood screws 6... 6 may be tightened again to fix the rail main body 1.

[0019]

According to the rail for door roller according to the present invention, not only both ends of the rail body but also parts other than both ends of the rail body after height adjustment are fixed to the flooring material with wood screws or the like. Also, even if the door wheel rolls on the rail, it does not vibrate, does not generate noise, and can quietly open and close the sliding door.

Also, when laying the rail for a door car, if the silicone resin is poured into the rail cover over the entire length and the rail body is pressed against the silicone resin layer, the silicone resin enters the gap between the rail body and the rail cover. Even after the silicone resin is cured, the silicone resin acts as a cushioning material, and even if the wheel of the door roller rolls on the rail body, no noise is generated between the rail body and the rail cover, so that the quieter Sliding door can be opened and closed.
