Abstract

An attachment apparatus for a vehicle body includes: a first roller rotatably disposed at a first hinge at one side of upper portion of a moving body and moving up and down with respect to a first fixing body; a link rotatably disposed with reference to the first hinge and extending to both directions; a second roller rotatably disposed at a second hinge at one end portion of the link and disposed at one side of the first roller; and a first elastic member disposed to elastically pull or push another end portion of the link so that the second hinge rotates with reference to the first hinge, wherein the first and second rollers respectively contact with a surface of the vehicle body.

First claim

What is claimed is:

1. An attachment apparatus for a vehicle body comprising:
a first roller rotatably disposed at a first hinge at one side of an upper portion of a moving body, the first roller moving up and down with respect to a first fixing body;
a link rotatably disposed at the first hinge and extending in two directions from the first hinge;
a second roller rotatably disposed at a second hinge at one end portion of the link and disposed at one side of the first roller; and
a first elastic member connected to another end portion of the link and disposed to elastically pull or push the another end portion of the link so that the second hinge rotates with reference to the first hinge,
wherein the first and second rollers are configured to contact with a surface of the vehicle body.

2. The attachment apparatus of claim 1 , further comprising:
a third roller rotatably disposed at a third hinge on another side of the upper portion of the moving body, the third roller configured to contact with the surface of the vehicle body.

3. The attachment apparatus of claim 2 , wherein:
the first and third rollers are configured to contact with a lower surface of the vehicle body, and
the second roller is configured to contact with a side surface of the vehicle body.

4. The attachment apparatus of claim 2 , wherein:
the second and third hinges are disposed side by side with the first hinge.

5. The attachment apparatus of claim 2 , wherein: outer circumference surfaces of the first, second, and third rollers are made of an acrylonitrile butadiene rubber (NBR).

6. The attachment apparatus of claim 2 , further comprising:
a second elastic member elastically supporting the moving body toward an upper side portion of the first fixing body.

7. The attachment apparatus of claim 2 , wherein:
the second hinge is disposed at the one end portion of the link with reference to the first hinge, and
the first elastic member pulls the another end portion of the link toward a lower side portion of the first fixing body.

8. A transfer device for transferring a vehicle body, comprising:
the attachment apparatus according to claim 1 ;
an arm at one end portion of which the attachment apparatus is disposed;
a rotation shaft connected with another end portion of the arm and rotating the arm; and
a frame on which the rotation shaft is rotatably disposed.

9. A transfer device, comprising:
the attachment apparatus according to claim 7 ;
an arm at one end portion of which the attachment apparatus is disposed;
a rotation shaft connected with another end portion of the arm and is configured to rotate the arm; and
a frame on which the rotation shaft is rotatably disposed.

10. A transfer device for assembling a vehicle body, comprising:
arms at each one end portions of which a first attachment apparatus and a second attachment apparatus are disposed;
rotation shafts connected with other end portions of the arms and is configured to rotate the arms respectively; and
a frame on which the rotation shafts are rotatably disposed,
wherein the first attachment apparatus includes:
a first roller rotatably disposed at a first hinge at one side of an upper portion of a moving body, the first roller moving up and down with respect to a first fixing body;
a link rotatably disposed at the first hinge and extending in two directions from the first hinge;
a second roller rotatably disposed at a second hinge at one end portion of the link and disposed at one side of the first roller; and
a first elastic member connected to the another end portion of the link and disposed to elastically pull or push another end portion of the link so that the second hinge rotates with reference to the first hinge,

wherein the first and second rollers are configured to contact with a surface of the vehicle body,
wherein the second attachment apparatus includes:
a first swing arm of which a lower portion of a center portion is rotatably disposed on a second fixing body with reference to a fourth hinge;
a second swing arm rotatably disposed at one end portion of the first swing arm with reference to a fifth hinge; and
a third swing arm rotatably disposed at another end portion of the first swing arm with reference to a sixth hinge, and

wherein upper surfaces of the second and third swing arms are configured to contact with a lower surface of the vehicle body.
