Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to a rail member for running a door roller in an opening/closing door or the like.

<Prior Art> Conventionally, this type of rail member is formed by bending a band-shaped metal plate, and as shown in FIG.
A supporting wall 23 having both side edges bent in the same direction.
a and 23b in series. The running surface 21 has a groove shape with a low center width,
The door roller runs on the running surface 21 along this groove.

<Problems to be solved by the invention> In the above, since the rail member is made of metal, a high-pitched sliding sound is generated when the door roller runs on the running surface 21, and furthermore, since the inside of the rail member is hollow, The sound is loud and harsh on the ears.

The present invention aims to solve the above problems by providing a rail member in which a filler is filled inside the rail body to suppress noise generation.

<Means for Solving the Problems> In order to achieve the above object, this invention includes an upper wall whose upper surface serves as the running surface of the door roller, a support wall in which both side edges of the upper wall are bent in the same direction, The rail member is composed of a metal rail body comprising a series of intermediate walls protruding from the center of the height of both support walls, and a filler formed in a shape that fits the inner upper part of the rail body. At the same time, the filling material is inserted between the upper wall and the intermediate wall of the rail body, and its upper surface is held in close contact with the lower surface of the upper wall of the rail body.

<Function> When assembling the rail member, the rail member can be easily assembled by simply inserting the filler material between the upper wall and the intermediate wall of the rail body, and the filler material does not fall off and is attached to the bottom surface of the upper wall. completely held on the intermediate wall in close contact with the

In this assembled state, when the door roller runs on the running surface of the upper surface of the rail body, sliding noise is generated, but since the filling material is in close contact with the upper wall of the rail body and the hollow part inside is filled, the sound is suppressed. The sound is low without echoing, and the occurrence of harsh high-pitched noise is prevented.

<Embodiment> FIGS. 1 and 2 show a rail member according to an embodiment of this invention. This rail member has a structure in which a filler 2 is inserted and held in a space inside the upper part of the rail body 1, and a plurality of anchor plates 12 are fixed at fixed distances perpendicular to the length direction of the filler 2. It is attached to the rail main body 1 by 13.

The rail main body 1 is formed by drawing a metal material, etc., and includes an upper wall 3, support walls 4a and 4b whose both side edges are bent in the same direction, and a height center of both support walls 4a and 4b. A series of intermediate walls 7a and 7b are formed to protrude from the top. The upper wall 3 has the width center of the upper surface positioned low to form a groove-shaped running surface 5 for the door roller, and the door roller runs along this running surface 5 and the inclined guide surfaces 6a and 6b on both sides. It's becoming like that.

Further, the intermediate walls 7a, 7b of this embodiment are formed by opening the width center at the center of the height of both supporting walls 4a, 4b and projecting inward by an appropriate width. Upper wall 3 and both supporting walls 4a, 4b
The space surrounded by and is the storage space for the filler 2. Note that the intermediate walls 7a, 7b are not limited to the form shown in FIG. 1, but may also be formed, for example, as shown in FIG.
The intermediate wall 7 may be in the form of a partition between the upper and lower parts, or the intermediate walls 7a and 7b may be in the form of protrusions with extremely small protruding widths, as shown in FIG.

The supporting walls 4a, 4b have lower ends folded inward to form opposing lower walls 11a, 11a, and the lower walls 11a, 11a and the intermediate wall 7
A space for accommodating the stopper fixture 13 is formed between the stopper 13a and 7b.

This fastening fixture 13 has a structure in which a tightening piece 16 is screwed onto a tightening shaft 15 having a head 14, and a hole 17 provided in an anchor plate 12.
When the tightening shaft 15 is tightened after the heel fixing device 13 is installed, the tightening pieces 16 are tightened and the lower walls 11a, 11a of the rail body 1 are tightened on the anchor plate 12. The width d of the tightening piece 16 is set smaller than the width of the gap 9 between the lower walls 11a, 11a of the rail body 1, and the length l is set shorter than the distance between the supporting walls 4a, 4b. The tightening piece 16 is positioned perpendicular to the anchor plate 12 as shown by the chain line in FIG. After that, both ends of the tightening piece 16 are attached to the supporting wall 4.
It is rotated until it hits the inner surfaces of a and 4b, and then the tightening shaft 15 is tightened.

Although the rail main body 1 has the door roller running surface 5 of the upper wall 3 in the shape of a groove, it may be in the shape of a protrusion.

Next, the filler 2 is made of a synthetic resin material such as vinyl chloride resin, and has a shape that matches the shape of the inner upper part of the rail body 1. In other words, the width of the filler 2 in the illustrated example is equal to that of the support wall 4 of the rail body 1.
a, 4b, and its height corresponds to the distance between the upper wall 3 and the intermediate walls 7a, 7b,
The upper surface is formed in an uneven shape corresponding to the lower surface of the upper wall 3 of the rail body 1.

As shown in FIG. 3, this filler 2 is inserted from one end between the upper wall 3 and intermediate walls 7a and 7b of the rail main body 1, and its upper surface is brought into close contact with the lower surface of the upper wall 3 of the rail main body 1. It is held on the intermediate walls 7a, 7b in this state.

As the filler 2, it is preferable to use a synthetic resin material such as vinyl chloride or an elastic material such as a rubber material, but the material is not limited thereto, and a foam material or the like may also be used.

Thus, the rail member is attached to a base material such as concrete or mortar with the upper wall 3 protruding. When the door roller runs on the running surface 5 of the door roller of the rail body 1, sliding noise is generated due to friction between the door roller and the running surface 5, but the filling material 2 is in close contact with the lower surface of the upper wall 3 and the rail body 1 Since the hollow part inside is filled, the sound does not resonate and becomes low, preventing the occurrence of harsh high-pitched noise.

<Effects of the invention> As mentioned above, this invention fills the inside of the rail body with filler material and holds it on the intermediate wall in close contact with the upper wall, thereby suppressing the metal noise generated when the door roller runs. be able to. In addition, the rail member can be easily assembled by simply inserting the filler material between the top wall of the rail body and the middle wall, and the filler material is completely retained on the middle wall without falling off. Achieves a remarkable effect of achieving the purpose.
