Abstract

A work support apparatus according to the present invention includes a base unit, a holding unit stands on the base unit and holds a work in a cantilevered state, and a tilt mechanism that makes the holding unit pivot with respect to the base unit. The holding unit includes a holding portion holding the work in a state in which a side portion of the work on the holding unit side is exposed. The tilt mechanism is an arcuate slide mechanism including an arcuate shape portion with respect to a virtual horizontal line as the center, and an abutting portion abutting against the arcuate shape portion.

First claim

What is claimed is:

1. A work support apparatus which supports a work and pivots the work about a horizontal axis, comprising:
a base unit;
a holding unit that holds an end portion, in an axis direction of the horizontal axis, of the work in a cantilevered state; and
a tilt mechanism that makes said holding unit pivot about the horizontal axis with respect to said base unit,
wherein said holding unit includes:
an adapter that is attached to the work and has a holding portion that holds the work in the cantilevered state in which the end portion of the work is exposed;
a frame which said tilt mechanism makes pivot about the horizontal axis; and
a connection portion that detachably connects said adapter and said frame,
said holding unit, in which said adapter and said frame are connected with each other through said connection portion, includes an opening portion at a center thereof,
said holding unit holds the end portion of the work in a state that the end portion, except for a portion which overlaps with said holding portion of said adapter, faces the opening portion, and
in said holding unit, only said adapter, via the holding portion, is directly connected with the work.

2. The work support apparatus according to claim 1 , wherein-said connection portion comprises two connection portions,
each of said two connection portions includes a first connecting portion and a second connecting portion,
said frame has an arcuate outer shape,
said adapter has an arcuate outer shape,
first connecting portions of said two connection portions are connected to both ends of said frame, respectively, and
second connecting portions of said two connection portions are connected to both ends of said adapter, respectively.

3. The work support apparatus according to claim 2 , wherein
said tilt mechanism comprises an arcuate slide mechanism comprising:
an arcuate shape portion that is provided on one of said base unit and said holding unit with respect to a virtual horizontal line as a center; and
an abutting portion that is provided on the other of said base unit and said holding unit and abuts against said arcuate shape portion, and
said abutting portion comprises a plurality of first rollers that abut against said arcuate shape portion.

4. The work support apparatus according to claim 3 , wherein
said abutting portion further comprises:
a plurality of second rollers that are provided on said base unit and abut against one surface and the other surface of said frame, respectively,
said one surface of said frame is a surface at a side in which the work is held in the cantilevered state,
said other surface of said frame is a surface at a side opposed to the side in which the work is held in the cantilevered state, and
rollers among said plurality of rollers, which abut against said one surface of said frame, abut against portions on a side of an inner edge of said frame.

5. The work support apparatus according to claim 1 , further comprising a fixing unit that releasably fixes said frame and said base unit at a plurality of tilt angles.

6. The work support apparatus according to claim 1 , wherein said base unit comprises:
a turntable portion on which said holding unit stands; and
a main body portion that supports said turntable portion pivotally about a vertical axis.

7. The work support apparatus according to claim 1 , wherein said frame comprises a first arcuate outer shape member,
said adapter comprises a second arcuate outer shape member,
said connection portion comprises a first connecting portion and a second connecting portion,
said first connecting portion detachably connects one end of said first arcuate outer shape member and one end of said second arcuate outer shape member,
said second connecting portion detachably connects another end of said first arcuate outer shape member and another end of said second arcuate outer shape member, and
the opening has a circular shape.

8. The work support apparatus according to claim 1 , wherein said adapter includes one end and another end which are spaced apart from each other in a direction of the horizontal axis,
said holding portion is provided with said one end of said adapter, and
said connection portion is provided with said another end of said adapter.

9. The work support apparatus according to claim 1 , wherein said holding portion is apart from the opening portion in a direction of the horizontal axis.

10. The work support apparatus according to claim 1 , wherein said holding portion is apart from said frame in a direction of the horizontal axis.

11. The work support apparatus according to claim 1 , wherein said holding portion is apart from said connection portion in a direction of the horizontal axis.

12. The work support apparatus according to claim 1 , wherein said holding portion is outwardly apart from the opening portion.

13. The work support apparatus according to claim 1 , wherein said adapter is slidably attachable and detachable to said connection portion.
