Abstract

A jigsaw that includes a housing assembly, a shoe member and an indicator. The housing assembly has a housing, a motor and transmission assembly received in the housing, an output member reciprocatingly driven by the motor and transmission assembly, and a trigger coupled to the housing and configured to control operation of the motor and transmission assembly. The housing defines a window. The shoe member is pivotally coupled to the housing. The indicator is pivotally disposed in the housing. A portion of the indicator is visible through the window. Movement of the indicator is responsive to movement of the shoe member such that a rotational position of the indicator is indicative of a position of the shoe member relative to the housing assembly.

First claim

What is claimed is:

1. A jigsaw comprising:
a housing assembly with a housing, a motor and transmission assembly received in the housing, an output member reciprocatingly driven by the motor and transmission assembly, and a trigger coupled to the housing and configured to control operation of the motor and transmission assembly;
a shoe member pivotally coupled to the housing; and
an indicator rotatably disposed in the housing, wherein the housing defines a window, wherein a portion of the indicator is visible through the window and wherein movement of the indicator is responsive to movement of the shoe member such that a rotational position of the indicator is indicative of a position of the shoe member relative to the housing assembly; and
further comprising a plurality of first gear teeth coupled to the indicator.

2. The jigsaw of claim 1 , wherein the indicator is disposed about a fluid conduit.

3. The jigsaw of claim 1 , wherein the fluid conduit and the indicator are coupled to one another for common rotation.

4. The jigsaw of claim 1 , wherein a plurality of second gear teeth are coupled to the shoe member and wherein the second gear teeth are meshingly engaged with the first gear teeth.

5. The jigsaw of claim 4 , wherein the second gear teeth and the shoe member are unitarily formed.

6. The jigsaw of claim 5 , wherein the detent mechanism comprises a detent structure and a detent follower, the detent structure being coupled to the second gear teeth and having a plurality of detent recesses, the detent follower being biased into engagement with the detent structure.

7. The jigsaw of claim 4 , wherein the second gear teeth are assembled to the shoe member.

8. The jigsaw of claim 7 , further comprising a locking mechanism for selectively locking the shoe member relative to the housing assembly, wherein the follower is mounted to the locking mechanism.

9. The jigsaw of claim 4 , further comprising a detent mechanism that is configured to resist pivoting motion of the shoe member relative to the housing assembly.

10. The jigsaw of claim 1 , wherein the indicator comprises an annular structure onto which indicia are disposed.

11. The jigsaw of claim 1 , further comprising a reference indicium on the housing proximate the window.

12. A jigsaw comprising:
a housing assembly with a housing, a motor and transmission assembly received in the housing, an output member reciprocatingly driven by the motor and transmission assembly, and a trigger coupled to the housing and configured to control operation of the motor and transmission assembly;
a shoe member pivotally coupled to the housing;
a locking mechanism for selectively locking the shoe member relative to the housing assembly;
an indicator rotatably disposed in the housing, wherein the housing defines a window, wherein a portion of the indicator is visible through the window and wherein movement of the indicator is responsive to movement of the shoe member such that a rotational position of the indicator is indicative of a position of the shoe member relative to the housing assembly;
a plurality of first gear teeth coupled to the indicator;
a plurality of second gear teeth are coupled to the shoe member and wherein the second gear teeth are meshingly engaged with the first gear teeth; and
a detent mechanism that is configured to resist pivoting motion of the shoe member relative to the housing assembly, the detent mechanism comprising a detent structure and a detent follower, the detent structure being coupled to the second gear teeth and having a plurality of detent recesses, the detent follower being biased into engagement with the detent structure.

13. The jigsaw of claim 12 , wherein the second gear teeth and the shoe member are unitarily formed.

14. The jigsaw of claim 12 , wherein the second gear teeth are assembled to the shoe member.

15. The jigsaw of claim 12 , wherein the follower is mounted to the locking mechanism.

16. The jigsaw of claim 12 , further comprising a reference indicium on the housing proximate the window.

17. The jigsaw of claim 12 , wherein the indicator is disposed about a fluid conduit.

18. The jigsaw of claim 17 , wherein the fluid conduit and the indicator are coupled to one another for common rotation.
