Abstract

A sander is provided and includes a housing, a power supply, a motor, a switch, and a switch actuation mechanism. The housing extends from a proximal end to a distal end and includes a first convex upper surface having a surface area A 1 . The power supply is coupled to the distal end of the housing. The motor is disposed within the housing and is powered by the power supply to drive an output member. The switch is in electrical communication with the power supply and is operable to selectively power the motor. The switch actuation mechanism is pivotably coupled to the proximal end of the housing and operable to actuate the switch. The switch actuation mechanism includes a second convex upper surface having a surface area A 2.

First claim

What is claimed is:

1. A sander comprising:
a housing having a first end and a second end opposite the first end, the housing also including a first convex upper surface;
a power supply coupled to the first end of the housing;
a motor disposed within the housing, the motor powered by the power supply and operable to drive an output member;
a switch in electrical communication with the power supply and operable to selectively power the motor; and
a switch actuation mechanism pivotably coupled to the second end of the housing via a hinge member and operable to actuate the switch, the switch actuation mechanism including a second convex upper surface;
wherein the switch actuation mechanism is pivotably coupled to the second end of the housing at a location forward of the motor;
wherein the switch actuation mechanism extends rearward of the motor, wherein the first end of the housing defines the rear of the sander and the second end of the housing defines the front of the sander; and
wherein, when the sander is placed on a flat horizontal surface, the motor is located entirely between the switch and the hinge member.

2. The sander of claim 1 , wherein the output member is a sanding platen.

3. The sander of claim 1 , further comprising a switch lock mechanism operable to secure the switch actuation mechanism in an actuated position.

4. The sander of claim 1 , further comprising a linkage assembly biasingly engaging the switch actuation mechanism, wherein the linkage assembly is operable to directly actuate the switch.

5. The sander of claim 4 , further comprising a switch lock mechanism operable to secure the linkage assembly in an actuated position relative to the switch.

6. The sander of claim 1 , wherein the switch is disposed closer to the first end of the housing than the second end of the housing.

7. The sanders of claim 6 , wherein the motor is located between the first end and the second end of the housing.

8. The sander of claim 1 , wherein the switch actuation mechanism further includes a concave lower surface disposed adjacent to the first convex upper surface.

9. The sander of claim 1 , wherein the switch is located rearwardly of the motor.

10. The sander of claim 1 , wherein the housing includes a first side and a second side opposite the first side, a line from the first side to the second side being perpendicular to a line from the first end to the second end;
wherein the switch actuation mechanism has a switch actuation mechanism lower surface;
wherein the switch actuation mechanism lower surface is convex along a direction from the first side to the second side.

11. A sander comprising:
a housing including a first convex upper surface;
a power supply coupled to the housing;
a motor disposed within the housing, the motor powered by the power supply and operable to drive an output member;
a switch in electrical communication with the power supply and operable to selectively power the motor; and
a switch actuation mechanism pivotably coupled to the housing and operable to actuate the switch, the switch actuation mechanism including a second convex upper surface;
wherein the output member is a sanding platen;
wherein the housing expends from a proximal end to a distal end, and wherein the switch is disposed in the distal end of the housing and the switch actuation mechanism is pivotably coupled to a hinge member disposed in the proximal end of the housing; and
wherein, when the sander is placed on a flat horizontal surface, the motor is located entirely between the switch and the hinge member.

12. The sander of claim 11 , further comprising a switch lock mechanism operable to secure the switch and the switch actuation mechanism in an actuated position.

13. The sander of claim 12 , further comprising a linkage assembly biasingly engaging the switch actuation mechanism, wherein the linkage assembly is operable to directly actuate the switch.

14. The sander of claim 11 , wherein the switch actuation mechanism is a paddle.

15. The sander of claim 14 , wherein the paddle has a lower surface; and
wherein the lower surface is convex along a first direction and a second direction, the first direction being perpendicular to the second direction.

16. The sander of claim 14 , wherein the sander housing comprises a rear, where the power source is coupled to the housing, and a front, which is opposite the rear;
wherein, when the sander is placed on a flat horizontal surface, the paddle is at a lower horizontal elevation in the front than in the rear.

17. The sander of claim 14 , wherein the sander housing comprises a rear and a front, which is opposite the rear;
wherein the sander housing comprises a first side and a second side opposite the first side, a line from the first side to the second side being perpendicular to a line from the front to the rear; and
wherein, when the sander is placed on a flat horizontal surface, the paddle extends lower at the first and second sides than at a middle of the sander housing.

18. A sander comprising:
a housing extending from a proximal end to a distal end, the housing including a first convex upper surface having a surface area;
a power supply coupled to the distal end of the housing;
a motor disposed within the housing, the motor powered by the power supply and operable to drive an output member;
a switch in communication with the power supply and operable to selectively power the motor;
a switch actuation mechanism pivotably coupled to the proximal end of the housing via a hinge member and operable to actuate the switch, the switch actuation mechanism including a second convex upper surface having a surface area and a concave lower surface disposed adjacent to the first convex upper surface of the housing, such that the switch actuation mechanism is a substantially dome-shaped member and the concave lower surface of the switch actuation mechanism wraps around the first convex upper surface of the housing;
wherein, when the sander is placed on a flat horizontal surface, the motor is located entirely between the switch and the hinge member.

19. The sander of claim 18 , wherein the power source is coupled to the housing at the distal end;
wherein, when the sander is placed on a flat horizontal surface, the switch actuation member is at a lower horizontal elevation at the proximal end than at the distal end.
