Abstract

A portable table saw in one embodiment includes a base, a first support post and a second support post, each of the first and second support post extending upwardly to a location higher than the base, at least one support rail having a first end portion supported by the first support post and a second end portion supported by the second support post, a saw movably mounted to the at least one support rail at a location between the first end portion and the second end portion, the saw positioned above the base and movable along the at least one support rail, and a first pivot mechanism configured to pivot the saw with respect to the base.

Claims (56)

1. A portable saw system comprising:

a base;

a first support post and a second support post, each of the first and second support post extending upwardly to a location higher than the base;

at least one support rail having a first end portion supported by the first support post and a second end portion supported by the second support post;

a saw movably mounted to the at least one support rail at a location between the first end portion and the second end portion, the saw positioned above the base and movable along the at least one support rail; and

a first pivot mechanism configured to pivot the saw with respect to the base, wherein:

the saw defines a saw blade plane;

the base defines a support plane; and

the first pivot mechanism is configured to pivot the saw with respect to the base about a pivot axis defined by the intersection of the saw blade plane and a plane parallel to the support plane.

2. The portable saw of claim 1 , wherein the first pivot mechanism comprises:

at least one arcuate guide surface having a first radius of curvature centered on the pivot axis;

a guide follower configured for movement along the at least one arcuate guide surface; and

a locking mechanism configured to positionally fix the guide follower with respect to the at least one arcuate guide surface.

3. The portable saw of claim 2 , wherein:

the first pivot mechanism comprises a guide slot including the at least one arcuate guide surface;

the guide follower is received within the guide slot; and

the guide follower includes a first articulating surface configured to articulate with the at least one arcuate guide surface.

4. The portable saw of claim 3 , wherein the first articulating surface is an arcuate surface having a second radius of curvature centered on the pivot axis.

5. The portable saw of claim 4 , wherein the at least one arcuate guide surface comprises:

a first arcuate guide surface configured to articulate with the first articulating surface; and

a second arcuate guide surface configured to articulate with a second articulating surface of the guide follower.

6. The portable table saw of claim 1 , wherein the saw is mounted to the at least one support rail by the first pivot mechanism.

7. The portable saw of claim 1 , wherein:

a first portion of the first pivot mechanism is fixedly connected to the first support post; and

a second portion of a second pivot mechanism is fixedly connected to the second support post.

8. The portable saw of claim 7 , wherein:

the first support post is fixedly connected to the base; and

the second support post is fixedly connected to the base.

9. A saw system comprising:

a base;

a first support post and a second support post, each of the first and second support post extending upwardly to a location higher than the base;

at least one support rail supported by the first support post at a first location and supported by the second support post at a second location;

a saw movably mounted to the at least one support rail at a location between the first location and the second location, the saw positioned above the base and movable along the at least one support rail; and

at least one pivot mechanism configured to pivot the saw with respect to the base, wherein:

the saw defines a saw blade plane;

the base defines a support plane; and

the at least one pivot mechanism is configured to pivot the saw with respect to the base about a pivot axis defined by the intersection of the saw blade plane and a plane parallel to the support plane.

10. The saw of claim 9 , wherein the at least one pivot mechanism comprises:

a first arcuate guide surface having a first radius of curvature with an origin on the pivot axis;

a guide follower configured for movement along the at least one arcuate guide surface; and

a locking mechanism configured to positionally fix the guide follower with respect to the at least one arcuate guide surface.

11. The saw of claim 10 , wherein:

the at least one pivot mechanism comprises a guide slot including the first arcuate guide surface;

the guide follower is received within the guide slot; and

the guide follower includes a first articulating surface configured to articulate with the first arcuate guide surface.

12. The saw of claim 11 , wherein the first articulating surface is an arcuate surface having a second radius of curvature with an origin on the pivot axis.

13. The saw of claim 12 , further comprising:

a second arcuate guide surface configured to articulate with a second articulating surface of the guide follower.

14. The table saw of claim 9 , wherein the saw is mounted to the at least one support rail by the at least one pivot mechanism.

15. The table saw of claim 9 , wherein:

the at least one pivot mechanism comprises a first pivot mechanism and a second pivot mechanism;

a first portion of the first pivot mechanism is fixedly connected to the first support post; and

a second portion of a second pivot mechanism is fixedly connected to the second support post.

16. The saw of claim 15 , wherein:

the first support post is fixedly connected to the base; and

the second support post is fixedly connected to the base.
