Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 119 words
An industrial robot having a robot hand attached to a horizontal robot arm by means of a robot wrist, comprising: a stationary robot base formed as the lowermost element of said industrial robot; a vertical motion unit arranged on said stationary robot base and including a vertical feed mechanism and a vertical guide fixedly standing on said robot base; a rotary motion unit mounted on said vertical motion unit and including therein a rotation drive mechanism; housing means mounted on said rotary motion unit for supporting therein said horizontal arm; and hollow structure means vertically extending through said vertical motion unit and said rotary motion unit for defining therein a vertical cavity formed as a wiring and piping space.
Claim 2
Dependent Claim 119 words
An industrial robot having a robot hand attached to a horizontal robot arm by means of a robot wrist, comprising: a stationary robot base formed as the lowermost element of said industrial robot; a vertical motion unit arranged on said stationary robot base and including a vertical feed mechanism and a vertical guide fixedly standing on said robot base; a rotary motion unit mounted on said vertical motion unit and including therein a rotation drive mechanism; housing means mounted on said rotary motion unit for supporting therein said horizontal arm; and hollow structure means vertically extending through said vertical motion unit and said rotary motion unit for defining therein a vertical cavity formed as a wiring and piping space.
Claim 3
Dependent Claim 55 words
An industrial robot as set forth in claim 1, wherein said hollow structure means comprises a hollow frame member formed as a movable part of said vertical motion unit, said hollow frame member having a slide slidably engaging said vertical guide, and a tubular member formed as a driven element of said rotary motion unit.
Claim 4
Dependent Claim 55 words
An industrial robot as set forth in claim 2, wherein said tubular member of said rotary motion unit is rotatably supported on a plate member fixed to the top of said hollow frame member of said vertical motion unit, said tubular member being arranged so as to be in alignment with said hollow frame member.
Claim 5
Dependent Claim 19 words
An industrial robot as set forth in claim 3, wherein said plate member supports therein said rotation drive mechanism.
