JP2531227Y2 - Soundproof door car for V type rail - Google Patents

Description

[Detailed description of the invention]

[0001]

The present invention is used for V-groove rails of various fittings, furniture, etc., to prevent the rotation noise generated by rolling of a door roller and to make sound insulation for a V- shaped rail capable of sliding smoothly. It is about door cars.

[0002]

2. Description of the Related Art Conventionally, in a V-rail of this type and a door wheel used for the V-rail, the V-rail is entirely formed of a metal material such as aluminum or brass. Further, at present, the door wheel used for the V-shaped rail has an outer ring formed by using a constituent material of a hard synthetic resin for an outer peripheral ring thereof.

[0003]

In the prior art, the noise and vibration caused by rolling are slightly reduced as compared with those of the V-shaped rail and the metal door roller, but the vibration and sound insulation are required significantly. However, there is a problem that a wheel made of a hard synthetic resin is not suitable for a door car. The present invention is an improvement of the above-mentioned conventional drawbacks, and its main object is to solve various problems of the soundproof door car in the conventional V-shaped rail, and to provide a door car corresponding to the V-shaped rail. A circular elastic ring is fitted inside a V-groove provided on the outer periphery of the inner ring part to ensure a soundproofing effect and a buffering effect, and a soundproofing for a V-shaped rail that firmly holds the elastic ring. It provides door cars.

[0004]

In order to achieve the above-mentioned object, a soundproof door car for a V-shaped rail according to the present invention comprises a wheel of a door car body and an inner ring portion made of a hard synthetic resin and a soft elastic body formed on the outer periphery thereof. It is integrally formed with an elastic ring. The inner ring, thereby forming a V groove on the entire periphery, on both sides of the V groove
The support side pieces each having a sharp tip are formed by projecting. Also,
With integrally formed a circular elastic ring body inside of the V-groove portion, and the outer periphery of the elastic ring body summer and formed projectingly provided from the V groove. Therefore, according to the present invention, when used for a metal V-shaped rail with high noise, the effect of reliably preventing noise and the elastic ring are firmly integrated and pushed out to be pushed out and damaged. There is no worrying effect.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional view of an embodiment of the present invention.
A longitudinal V- shaped groove (8) is formed on the surface of the rail- shaped main body (2). Wheels (3) of the door roller body (1) rolling on the V-grooves (8) of the rail body (2) are rotatably mounted on side frames (10) with an axle (11). . The wheel (3) is integrally formed with an inner ring portion (4) made of a hard synthetic resin constituting an inner periphery and an elastic ring (7) made of a soft synthetic resin located on the outer periphery. ing. Wherein the inner ring (4), to form a bearing projection (9) to the contact portion of the axle (11), are allowed to form V grooves (5) on the outer circumference. The V groove (5) is opposite the tip on either side of the V groove are constituted by projecting TogaTsuta support side piece (6) (6). Reference numeral (12) indicates a lower frame such as a lower frame.

[0006]

The present invention is constructed as described above. In order to use this soundproof door with a V-shaped rail, a rail body (2) having a lower frame (12) provided with a V-shaped groove (8) in the longitudinal direction. the embedded, protruding from the outer periphery of the outer ring (3) with respect to the V groove (8)
The elastic ring (7) provided with a circular shape is rolled and used to ensure cushioning and soundproofing.

[0007]

[Effects of the Invention] As described above, according to the present invention, it is possible to prevent the noise caused by the vibration and rolling of the door bogie body with respect to the V-shaped rail made of metal or the like, thereby enabling the smooth operation of the door car and the buffering of the vibration of the fittings. There are effects such as doing. And the wheel of the door car body is made of an inner ring made of hard synthetic resin and a soft synthetic resin
Since they are formed with an elastic ring made of steel , they are firmly integrated, and there is an effect that the wheels are strengthened without being damaged. In addition, the elastic ring has an effect of stably rolling on the V-shaped rail, sufficiently absorbing and absorbing noise. Further, Yotsute that tip provided on both sides of the outer periphery of the inner ring portion is form form the TogaTsuta <br/> support side piece, elastic annulus rigidly
Invaded housed fixed inside Rutotomoni, elastic ring body is an excellent effect that from being extruded One suited outwardly Ru is Wataru connexion used sufficiently held prolonged on both sides of the front end of the support side piece.
