Description

The present invention relates to a guide roller device for a sliding door.

b. Conventional technology and its problems Conventionally, there have been four-wheeled vehicles and the like in which a door is slid to open and close the door.

FIG. 12 shows a slide door 1 of such a vehicle.

In this slide door 1, a slide door hinge 2 with a guide roller and an upper arm 3 are installed by bolts 4 and the like, and the guide roller 5 moves within a guide rail 6 installed on the vehicle body side. .

However, in this conventional vehicle, the guide roller 5
The guide roller 5 is fitted to the slide door hinge 2 and the pin 7 erected on the upper arm 3 and then further attached to the guide roller 5 so that the guide roller 5 does not come off from the pin. Was being prevented from coming off.

Further, conventionally, noise may be generated between the guide roller 5 and the pin 7 into which the guide roller 5 is fitted.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a guide roller device for a slide door that can reduce the number of parts and that can prevent the generation of noise.

In FIG. 12, reference numeral 8 is a lower arm that supports the slide door 1 together with the slide door hinge 2 and the upper arm 3.

c. Means for Solving the Problems In the present invention, in order to achieve the above object, a small diameter portion is formed on the shaft portion of the pin, and a protrusion is formed on the peripheral surface of the shaft insertion hole of the guide roller. The guide roller is fitted to the shaft portion of the pin against the elasticity of the protrusion so that the protrusion of the guide roller is located at the small diameter portion of the pin.

d. Example Hereinafter, an example of a guide roller device for a sliding door according to the present invention will be described in detail with reference to the accompanying drawings.

1 to 7 show an embodiment of the present invention, and FIGS. 1 to 3 show a slide door hinge 10 with a guide roller.
4 shows the upper arm 11 with a guide roller.

A pin 12 as shown in FIG. 5 is erected on the sliding door hinge 10 and the upper arm 11, and a guide roller 13 as shown in FIGS. 6 and 7 is fitted on the pin 12.

Here, the pin 12 includes the planting portion 12a, the flange 12b, and the shaft portion 1
2c, and the shaft portion 12c is formed with a small diameter portion 12d having a diameter smaller than that of the shaft portion 12c.

The guide roller 13 is made of resin (66 nylon), and the small diameter portion 12 of the pin 12 is provided on the peripheral surface of the shaft insertion hole 13a.
A plurality of protrusions 13b are integrally formed at appropriate positions corresponding to the formation positions of.

The sliding door hinge 10 includes an attachment arm portion 10a and a head portion 10b rotatably supported by the arm,
From the head part, a bracket 10c on which the pin 12 is installed
Is projected.

The bracket 10c and the head portion 11a of the upper arm 11 are provided with holes 10d and 11d, and the planting portion 12a of the pin 12 is fitted into the holes and is caulked so as not to come off.

After that, the guide roller 13 is fitted to the shaft portion 12c of the planted pin 12 against the elastic force of the projection 13b, and the installation is performed when the projection reaches the small diameter portion 12d of the pin 12. Complete.

In this state, the guide roller 13 is rotatably supported by the pin 12, and a grease reservoir is formed between the small diameter portion 12d of the pin and the peripheral surface of the shaft insertion hole 13a of the guide roller 13.

By injecting grease into this grease reservoir, an appropriate amount of grease is retained in the grease reservoir and the pin 12 and the guide roller 13 are lubricated.

In FIGS. 1 to 3, 14 is a bearing and 15 is a pin.

8 to 11 show another embodiment of the guide roller device for a sliding door according to the present invention.

In this embodiment, as in the case of the above embodiment, the pin 20 is
It is composed of a planted portion 20a, a flange 20b and a shaft portion 20c, and a small diameter portion 20d is formed on the shaft portion.

Further, the guide roller 21 according to the present embodiment has a wedge-shaped protrusion 21b formed on the peripheral surface of the shaft insertion hole 21a.

The wedge-shaped protrusion 21b has an inclined surface 21c that allows the guide roller
The pin 20 can be easily fitted into the shaft portion 20c, and the upright surface 21d of the projection 21b prevents the pin 21 from being pulled out.

The guide roller device according to the present invention is not limited to the above-mentioned embodiments, and the number of the protrusions formed on the peripheral surface of the shaft insertion hole of the guide roller may be one or plural, and may be dotted. Of course, it may be formed as a ring or a ring.

e. Effect of the Invention As described above, according to the guide roller device for a slide door of the present invention, by fitting the guide roller to the pin, the guide roller is prevented from being pulled out from the pin at the same time. Therefore, a separate guide roller retaining component is not required.

Therefore, the number of parts can be reduced, and the assembling workability of the device can be improved.

Further, according to the guide roller device of the present invention, since the grease reservoir is formed between the pin and the guide roller, and the pin and the guide roller are lubricated,
It is possible to prevent the generation of noise during that time.
