BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide mechanism for a slide body, and more specifically, a projection of the slide body is slidably guided in a guide groove of a guide rail, and the guide is provided on the outer periphery of the projection. The present invention relates to a guide mechanism for a slide body in which a slider that contacts the inner surface of a groove is fitted.

[0002]

2. Description of the Related Art This type of guide mechanism is incorporated in, for example, a roof opening / closing device for opening and closing a lid provided in an opening of a roof panel of an automobile.

In the case of the guide mechanism incorporated in the roof opening / closing device, the shoe connected to the side portion of the lid is used as a slide body, and the slide body is extended along the left and right side edges of the roof opening. It will be guided slidably on the rail. That is, the shoe is provided with a protrusion that is slidably guided in the guide groove of the guide rail, and a slider that is in contact with the inner surface of the guide groove of the guide rail is fitted to the outer periphery of the protrusion. The slider prevents the rattling of the shoe and eventually the lid.

Conventionally, a guide mechanism incorporated in such a roof opening / closing device has a structure in which a protrusion of a slide body such as a shoe has a rectangular cross-section and an annular slider is fitted to the protrusion. Was becoming. Also, the slider may be partially curved (Actual No. Sho 63-182922), or a space is provided inside the slider (Actual No. Sho 63-182923).
In some cases, the slider is elastically deformed so as to be interposed between the projection of the slide body and the guide rail to more reliably prevent the occurrence of backlash.

[0005]

However, in such a conventional guide mechanism, since the protrusion of the slide body has a simple rectangular cross section, the slide body slides and the slider contacting the guide rail slides. When the body is bent rearward in the sliding direction, the amount of bending of the slider is not absorbed at all by the projecting side of the slide body. Therefore, there is a problem in that the bent portion of the slider is strongly pushed between the protrusion of the slide body and the guide rail, which hinders smooth slide of the slide body. In addition, as described above, in the case where the slider is partially curved or a space is provided inside the slider, the slider is not flat on the protrusion of the slide during the sliding operation. Since it is easy to deform irregularly while shifting to the rear side in the sliding direction along the surface, there is a problem that the friction resistance between the slider and the guide rail changes and smooth sliding of the slide body is obstructed. there were.

An object of the present invention is to allow a slide body to slide smoothly by absorbing the deflection of the slide body on the protrusion side of the slide body and regulating the form of the deflection of the slide body. It is to provide a body guiding mechanism.

[0007]

According to the guide mechanism for a slide body of the present invention, the projection of the slide body is slidably guided in the guide groove of the guide rail, and the guide groove is formed on the outer periphery of the projection. In a guide mechanism for a slide body in which a slider that is in contact with an inner surface is fitted, an outer peripheral surface of the protrusion is provided with a recessed portion that allows the slide body to bend inward. .

[0008]

The guide mechanism for a slide body of the present invention has a recess formed on the outer peripheral surface of the protrusion of the slide body to which the slider is fitted.
By allowing the slider to bend by the recessed portion, when the protrusion of the slide body slides in the guide groove of the guide rail, the bent portion generated in the slider can be pushed into the slide portion. Avoid it and make the slide of the slide smooth.

Further, by restricting the form of the flexure generated in the slider by the above-mentioned depressions, a large change in the sliding resistance due to the irregular flexure of the slider is suppressed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

This embodiment is an example of application as a guide mechanism incorporated in a roof opening / closing device of an automobile.

First, FIG. 6 is a plan view of a roof 1 of an automobile, in which the left side is the front side of the automobile. In FIG. 6, an opening 1a is formed in the roof 1, and one continuous guide rail 2 is substantially U-shaped in plan view at the left and right side edges and the front edge of the opening 1a. It is curved and attached. The guide rail 2 has a cross-sectional shape as shown in FIG. 7.
A first guide groove 2a having a U-shaped cross section and a second guide groove 2b having a C-shaped cross section are provided symmetrically.

In FIG. 6, reference numeral 3 is a lid, and a plurality of shoes (slide bodies) are attached to the left and right side portions thereof via a link mechanism or the like. 2, FIG. 3, FIG. 4, FIG. 5 and FIG. 7, one shoe is conceptually represented by reference numeral 4. A plurality of shoes connected to the lid 3 are slidably guided in the first guide grooves 2a on the left and right of the guide rail 2 as in the illustrated shoe 4. That is, on each of the left and right side portions of the shoe 4, there are provided two front and rear projections 5 slidably guided in the left and right first guide grooves 2a, 2a, respectively.
Further, a slider 6 made of synthetic resin is fitted to each protrusion 5.

As shown in FIG. 1, the projection 5 has a laterally elongated elliptical shape, and recesses 5a are formed on the upper and lower surfaces thereof. Further, a hook-shaped stopper portion 5b as shown in FIG. 2 is formed on the protruding portion of the protruding portion 5. On the other hand, as shown in FIG. 2, the slider 6 has a tubular portion 6 having an elliptical cross section.
A has a bottom portion 6b at one end, and the bottom portion 6b is formed with a through hole 6c having a quadrangular cross section and a shape gradually narrowing toward the inside of the tubular portion 6a. And this slider 6
3 is fitted into the protrusion 5 as shown in FIG. 3, and the through hole 6c of the bottom 6b thereof engages with the stopper 5b of the protrusion 5 to prevent the slider 6 itself from coming off. As shown in FIG. 3, the slider 6 when fitted to the protrusion 5 in this manner is
The upper and lower intermediate portions 6d, 6d bulge outwardly and project
It is separated from the hollow portion 5a.

In FIG. 6, 11a and 11b are geared cables, which are individually slidably guided in the second guide grooves 2b, 2b on the left and right of the guide rail 2, respectively. One geared cable 11
a is attached to the left side of the lid 3 and is attached to the shoe 4
Similarly, the geared cable 11b is connected to one of the plurality of shoes guided by the guide rail 2, and the other geared cable 11b is attached to the right side portion of the lid 3 and is the same as the shoe 4 described above. It is connected to one of a plurality of shoes guided by two. The geared cables 11a and 11b mesh with the drive gear 13 that is normally or reversely rotated by the drive motor 12, and the normal or reverse rotation of the drive gear 13 causes the geared cables 11a and 11b to slide synchronously. As a result, the lid 3 is opened and closed.

Next, the operation will be described.

The protrusion 5 of the shoe 4 to which the slider 6 is fitted is slidably guided in the first guide groove 2a of the guide rail 2 as shown in FIG. It is interposed between the protrusion 5a and the guide groove 2a to prevent the shoe 4 and thus the lid 3 from rattling. Further, the upper and lower intermediate portions 6d, 6d of the slider 6 are pushed by the inner surface of the guide groove 2a as shown by the chain double-dashed line in FIG. 1 and deformed toward the depressions 5a, 5a side of the protrusion 5. ing.

When the shoe 4 slides along the first guide groove 2a as the lid 3 opens and closes,
The upper and lower intermediate portions 6d, 6d of the slider 6 are bent as shown by the solid line in FIG. 1 and enter the depressions 5a, 5a of the protrusion 5. That is, when the protrusion 5 is slid to the right in FIG. 1 together with the shoe 4, the slider 6 is bent to the left in FIG. 1 due to the friction with the guide groove 2a. Appears in the upper and lower intermediate portions 6d, 6d of the slider 6,
The bent portion enters the recessed portions 5a, 5a of the protrusion 5. Similarly, when the protrusion 5 slides to the left in FIG. 1 together with the shoe 4, the slider 6 bends to the right in FIG. 1, and the bent portion is inside the depressions 5 a and 5 a of the protrusion 5. Will enter.

As described above, since the flexure of the slider 6 is allowed by the recess 5a of the projection 5, the flexed portion of the slider 6 is pushed between the projection 5 and the guide groove 2a. And the shoe 4 slides smoothly. Also,
Since the intermediate portion 6d of the slider 6 bends along the recess 5a of the protrusion 5, the shape of the bending is restricted. Therefore, there is no large change in the sliding resistance due to the irregular bending of the slider 6, and the shoe 4 slides more smoothly.

Next, a specific example of the plurality of shoes guided by the guide rail 2 as in the case of the shoe 4 will be briefly described with reference to FIG.

In this example, the front shoe 4-1, the drive shoe 4-2, and the rear shoe 4-3 are connected to the left and right side portions of the lid 3, and the lid 3 is made of glass. A bracket 3a is attached to the back side thereof. The arm portion 4-1a of the front shoe 4-1 is pin-connected to a portion of the bracket 3a on the front side of the vehicle body, and the rear shoe 4-3 is on the rear side of the bracket 3a on the vehicle body side via the first link member 21. It is pin-coupled to the part. The drive shoe 4-2 has a predetermined guide groove 4-2a.
