Abstract

A machine tool capable of restraining dirt on the footstool and improving setup efficiency. The machine tool includes a machine body having a splash guard surrounding a machining area and a door capable of closing an opening of the splash guard. A footstool is kept mounted on the machine body changeably in place with respect to the machine body. The footstool kept mounted on the machine body is capable of being in a place on an outside of the machine body when the door is closed. The footstool kept mounted on the machine body is capable of being brought to a setup place inside the machining area from the outside of the machine body through the opening when the door is open.

First claim

What is claimed is:

1. A machine tool comprising:
a machine body having a splash guard surrounding a machining area, the machine body also having a door capable of closing an opening of the splash guard; and
a footstool kept mounted on the machine body changeably in place with respect to the machine body such that a location of the footstool is able to be changed relative to the machine body while the footstool is mounted on the machine body;
wherein the footstool kept mounted on the machine body is capable of being in a place on an outside of the machine body and splash guard when the door has been closed and wherein the footstool is capable, while remaining mounted on the machine body, of being brought to a setup place inside the machining area from the outside of the machine body through the opening when the door has been opened; and
wherein the footstool comprises a footboard movably attached to the machine body so as to be movable from the place outside of the machine body to the setup place, and
wherein the footstool further comprises a leg that is pivotably mounted to the footboard for pivoting relative to the footboard, wherein the leg is configured to support the footboard when the footboard is in the setup place.

2. The machine tool of claim 1 , wherein the footboard comprises a footboard surface where an operator steps when the footstool is held in the setup place, and wherein the footboard surface is in a first orientation when the footboard is in the place outside of the machine body and is in a second, different, orientation when the footboard is in the setup place.

3. The machine tool of claim 2 , wherein the footstool is movable in a horizontal direction between different positions when the footstool is held in the place outside the machine body when the door is closed.

4. The machine tool of claim 3 , wherein the footstool is movable in a horizontal direction between different positions when the footstool is held in the setup place.

5. The machine tool of claim 4 , wherein the footstool further comprises a tilt mechanism configured to facilitate the pivoting of the leg with respect to the footboard,
wherein the tilt mechanism allows the leg to pivot between a use state in which the leg supports the footboard and a non use state in which the leg is angled along the footboard, and
wherein the machine body is provided with a rest capable of receiving an end of the leg when the footstool is held in the setup place and the leg is held in the use state.

6. The machine tool of claim 3 , wherein the footstool further comprises a tilt mechanism configured to facilitate the pivoting of the leg with respect to the footboard,
wherein the tilt mechanism allows the leg to pivot between a use state in which the leg supports the footboard and a non use state in which the leg is angled along the footboard, and
wherein the machine body is provided with a rest capable of receiving an end of the leg when the footstool is held in the setup place and the leg is held in the use state.

7. The machine tool of claim 2 , wherein the footstool is movable in a horizontal direction between different positions when the footstool is held in the setup place.

8. The machine tool of claim 7 , wherein the footstool further comprises a footboard mounted on the machine body changeably in place with respect to a tilt mechanism configured to facilitate the pivoting of the leg with respect to the footboard,
wherein the tilt mechanism allows the leg to pivot between a use state in which the leg supports the footboard and a non use state in which the leg is angled along the footboard, and
wherein the machine body is provided with a rest capable of receiving an end of the leg when the footstool is held in the setup place and the leg is held in the use state.

9. The machine tool of claim 2 , wherein the footstool further comprises a tilt mechanism configured to facilitate the pivoting of the leg with respect to the footboard,
wherein the tilt mechanism allows the leg to pivot between a use state in which the leg supports the footboard and a non use state in which the leg is angled along the footboard, and
wherein the machine body is provided with a rest capable of receiving an end of the leg when the footstool is held in the setup place and the leg is held in the use state.

10. The machine tool of claim 1 , wherein the footstool is movable in a horizontal direction between different positions when the footstool is held in the place outside the machine body when the door is closed.

11. The machine tool of claim 10 , wherein the footstool is movable in a horizontal direction between different positions when the footstool is held in the setup place.

12. The machine tool of claim 11 , wherein the footstool further comprises a tilt mechanism configured to facilitate the pivoting of the leg with respect to the footboard,
wherein the tilt mechanism allows the leg to pivot between a use state in which the leg supports the footboard and a non use state in which the leg is angled along the footboard, and
wherein the machine body is provided with a rest capable of receiving an end of the leg when the footstool is held in the setup place and the leg is held in the use state.

13. The machine tool of claim 10 , wherein the footstool further comprises a tilt mechanism configured to facilitate the pivoting of the leg with respect to the footboard,
wherein the tilt mechanism allows the leg to pivot between a use state in which the leg supports the footboard and a non use state in which the leg is angled along the footboard, and
wherein the machine body is provided with a rest capable of receiving an end of the leg when the footstool is held in the setup place and the leg is held in the use state.

14. The machine tool of claim 1 , wherein the footstool is movable in a horizontal direction between different positions when the footstool is held in the setup place.

15. The machine tool of claim 14 , wherein the footstool further comprises a tilt mechanism configured to facilitate the pivoting of the leg with respect to the footboard,
wherein the tilt mechanism allows the leg to pivot between a use state in which the leg supports the footboard and a non use state in which the leg is angled along the footboard, and
wherein the machine body is provided with a rest capable of receiving an end of the leg when the footstool is held in the setup place and the leg is held in the use state.

16. The machine tool of claim 1 , wherein the footstool further comprises a tilt mechanism configured to facilitate the pivoting of the leg with respect to the footboard,
wherein the tilt mechanism allows the leg to pivot between a use state in which the leg supports the footboard and a non use state in which the leg is angled along the footboard, and
wherein the machine body is provided with a rest capable of receiving an end of the leg when the footstool is held in the setup place and the leg is held in the use state.

17. The machine tool of claim 1 , wherein the machine tool is in the form of a lathe.

18. The machine tool of claim 17 , wherein the lathe comprises:
a workpiece spindle for holding a workpiece; and
a tool post for supporting machining tools.

19. The machine tool of claim 18 , wherein the machining tools include a turning tool and a rotary tool.

20. The machine tool of claim 19 , wherein the rotary tool comprises a drill or an end mill.
