Abstract

A thickness planer includes a motor, a planing part, a placing part, a feeding part, and a battery pack mounting unit. The planing part is configured to be driven by the motor and plane a workpiece. A workpiece is placeable on the placing part. The feeding part is configured to feed the workpiece placed on the placing part to the planing part. A battery pack for supplying power to the motor is attachable to the battery pack mounting unit.

First claim

What is claimed is:

1. A thickness planer, comprising:
a motor;
a planing part that is configured to be driven by the motor and plane a workpiece;
a placing part on which the workpiece is placeable;
a feeding part that is configured to feed the workpiece placed on the placing part to the planing part; and
a battery pack mounting unit to which a battery pack for supplying power to the motor is attachable.

2. The thickness planer as defined in claim 1 , wherein, when an area through which the workpiece passes while being fed by the feeding part is defined as a feeding area, the battery pack mounting unit is configured such that the battery pack mounting unit and the battery pack attached to the battery pack mounting unit lie in a position avoiding the feeding area.

3. The thickness planer as defined in claim 1 , wherein the battery pack mounting unit is configured such that the battery pack is removably attached thereto.

4. The thickness planer as defined in claim 1 , wherein the battery pack is usable as a power source for other power tools.

5. The thickness planer as defined in claim 1 , further comprising:
a motor housing that houses the motor, wherein:
the placing part has a placing surface on which the workpiece is placeable,
when a direction in which the feeding part feeds the workpiece is defined as a front-rear direction, a direction perpendicular to the placing surface is defined as a vertical direction, and in the vertical direction, a direction from the placing part toward the workpiece is defined as an upper direction and a direction opposite to the upper direction is defined as a lower direction,
the battery pack mounting unit is arranged above the motor housing.

6. The thickness planer as defined in claim 5 , further comprising:
a cover part that is provided above the motor housing and covers at least part of the motor housing when the thickness planer is viewed from above, wherein:
the battery pack mounting unit is arranged above the motor housing and below the cover part.

7. The thickness planer as defined in claim 6 , further comprising:
a left side member and a right side member that are provided on left and right sides of the motor housing, respectively, when a direction perpendicular to the front-rear direction and the vertical direction is defined as a left-right direction, wherein:
the battery pack mounting unit is arranged in an area surrounded by the motor housing, the cover part and the left and right side members.

8. The thickness planer as defined in claim 7 , wherein the battery pack mounting unit is mounted to a lower surface of the cover part.

9. The thickness planer as defined in claim 8 , wherein:
the battery pack mounting unit is configured such that a plurality of battery packs can be attached thereto, and
the plurality of battery packs attached to the battery pack mounting unit are electrically connected to the motor in series.

10. The thickness planer as defined in claim 5 , wherein the battery pack mounting unit is mounted on top of the motor housing.

11. The thickness planer as defined in claim 5 , further comprising:
a battery pack housing part that houses at least parts of the battery pack mounting unit and the battery pack attached to the battery pack mounting unit, wherein:
the battery pack housing part is arranged above the motor housing.

12. The thickness planer as defined in claim 5 , further comprising:
a cover part that is provided above the motor housing and covers at least part of the motor housing when the thickness planer is viewed from above, and
a battery pack housing part that houses at least parts of the battery pack mounting unit and the battery pack attached to the battery pack mounting unit, wherein:
the battery pack housing part is configured to house at least parts of the battery pack mounting unit and the battery pack attached to the battery pack mounting unit below an upper surface of the cover part.

13. The thickness planer as defined in claim 1 , further comprising:
a scattering prevention part that is configured to prevent scattering of shavings generated and discharged by planing operation of the planing part, wherein:
the placing part has a placing surface on which the workpiece is placeable,
when a direction in which the feeding part feeds the workpiece is defined as a front-rear direction, a direction perpendicular to the placing surface is defined as a vertical direction, and in the vertical direction, a direction from the placing part toward the workpiece is defined as an upper direction,
the battery pack mounting unit is mounted on top of the scattering prevention part.

14. The thickness planer as defined in claim 1 , further comprising:
a housing; and
an energizing member that is electrically connected to the motor and extends to an outside of the housing, wherein:
the battery pack mounting unit is electrically connected to the motor via the energizing member.

15. The thickness planer as defined in claim 1 , further comprising:
a motor housing that houses the motor, wherein:
the placing part has a placing surface on which the workpiece is placeable,
when a direction in which the feeding part feeds the workpiece is defined as a front-rear direction, a direction perpendicular to the placing surface is defined as a vertical direction, and in the vertical direction, a direction from the placing part toward the workpiece is defined as an upper direction and a direction opposite to the upper direction is defined as a lower direction,
the battery pack mounting unit is mounted to the motor housing and configured such that the battery pack is attached thereto by being slid in a prescribed sliding direction, and configured such that the battery pack is moved in the vertical direction as being moved in the front-rear direction when the battery pack is slid in the sliding direction.

16. The thickness planer as defined in claim 1 , further comprising:
a motor housing that houses the motor, wherein:
the placing part has a placing surface on which the workpiece is placeable,
when a direction in which the feeding part feeds the workpiece is defined as a front-rear direction, a direction perpendicular to the placing surface is defined as a vertical direction, and a direction perpendicular to the front-rear direction and the vertical direction is defined as a left-right direction,
the battery pack mounting unit is arranged on a left side or a right side of the motor housing.

17. The thickness planer as defined in claim 1 , wherein:
the placing part has a placing surface on which the workpiece is placeable,
when a direction in which the feeding part feeds the workpiece is defined as a front-rear direction, a direction perpendicular to the placing surface is defined as a vertical direction, and a direction perpendicular to the front-rear direction and the vertical direction is defined as a left-right direction,
