Abstract

A cutting guide includes a first guide structure and a second guide structure. The first guide structure includes (i) a first base, (ii) a first saw support attached to the first base and defining a first saw contact surface, and (iii) a second saw support attached to the first base and defining a second saw contact surface that is spaced apart from the first saw contact surface so as to define a first elongated cutting slot therebetween. The second guide structure includes (i) a second base, (ii) a third saw support attached to the second base and defining a third saw contact surface, and (iii) a fourth saw support attached to the second base and defining a fourth saw contact surface that is spaced apart from the third saw contact surface so as to define a second elongated cutting slot therebetween.

First claim

What is claimed is:

1. A cutting guide, comprising:
a first guide structure including (i) a first base, (ii) a first saw support attached to said first base and defining a first saw contact surface, and (iii) a second saw support attached to said first base and defining a second saw contact surface that is spaced apart from said first saw contact surface so as to define a first elongated cutting slot therebetween; and
a second guide structure including (i) a second base, (ii) a third saw support attached to said second base and defining a third saw contact surface, and (iii) a fourth saw support attached to said second base and defining a fourth saw contact surface that is spaced apart from said third saw contact surface so as to define a second elongated cutting slot therebetween,
wherein said first elongated cutting slot defines (i) a first slot portion, (ii) a second slot portion that is contiguous with said first slot portion, and (iii) a third slot portion that is contiguous with said second slot portion, said second slot portion being interposed between said first slot portion and said third slot portion,
wherein said second elongated cutting slot defines (i) a fourth slot portion, (ii) a fifth slot portion that is contiguous with said fourth slot portion, and (iii) a sixth slot portion that is contiguous with said fifth slot portion, said fifth slot portion being interposed between said fourth slot portion and said sixth slot portion,
wherein said first base defines a first workpiece passage and a second workpiece passage that are spaced apart from each other so as to define a first workpiece space therebetween,
wherein said second base defines a third workpiece passage and a fourth workpiece passage that are spaced apart from each other so as to define a second workpiece space therebetween,
wherein said first base defines a first cavity positioned below said first elongated cutting slot,
wherein said second base defines a second cavity positioned below said second elongated cutting slot,
wherein said first cavity includes (i) said first workpiece space, (ii) a first cutting member start space positioned on one side of said first workpiece space, and (iii) a first cutting member end space positioned on an opposite side of said first workpiece space,
wherein said second cavity includes (i) said second workpiece space, (ii) a second cutting member start space positioned on one side of said second workpiece space, and (iii) a second cutting member end space positioned on an opposite side of said second workpiece space,
wherein (i) said first cutting member start space is positioned below said first slot portion, (ii) said first workpiece space is positioned below said second slot portion, and (iii) said first cutting member end space is positioned below said third slot portion, and
wherein (i) said second cutting member start space is positioned below said fourth slot portion, (ii) said second workpiece space is positioned below said fifth slot portion, and (iii) said second cutting member end space is positioned below said sixth slot portion.

2. The cutting guide of claim 1 , wherein:
said first guide structure includes a first guide end portion,
said second guide structure includes a second guide end portion, and
said first guide end portion is attached to said second guide end portion.

3. The cutting guide of claim 1 , wherein:
said first elongated cutting slot is oriented along a first axis,
said second elongated cutting slot is oriented along a second axis, and
said first axis and said second axis intersect each other to define an acute angle.

4. The cutting guide of claim 3 , wherein:
said acute angle possesses a magnitude Θ, and
45°<Θ<75°.

5. The cutting guide of claim 1 , wherein:
said first saw contact surface defines a first plane,
said second saw contact surface defines a second plane, and
said first plane and said second plane intersect each other to define a first angle.

6. The cutting guide of claim 5 , wherein:
said third saw contact surface defines a third plane,
said fourth saw contact surface defines a fourth plane, and
said third plane and said fourth plane intersect each other to define a second angle.

7. The cutting guide of claim 6 , wherein:
said first angle possesses a first magnitude Θ 1 ,
80°<Θ1<100°, and

said second angle possesses a second magnitude Θ 2 , and
80°<Θ2<100°.

8. The cutting guide of claim 1 , further comprising an abutment structure defining an abutment surface, wherein:
said first base includes a first passage surface and a second passage surface that are spaced apart from each other so as to define said first workpiece passage therebetween,
said second base includes a third passage surface and a fourth passage surface that are spaced apart from each other so as to define said third workpiece passage therebetween,
said abutment surface is positioned under both said first elongated cutting slot and said second elongated cutting slot, and
said first passage surface, said third passage surface, and said abutment surface lie in a plane.

9. A cutting guide, comprising:
a first guide structure including (i) a first base, (ii) a first saw support attached to said first base and defining a first saw contact surface, and (iii) a second saw support attached to said first base and defining a second saw contact surface that is spaced apart from said first saw contact surface so as to define a first elongated cutting slot therebetween; and
a second guide structure including (i) a second base, (ii) a third saw support attached to said second base and defining a third saw contact surface, and (iii) a fourth saw support attached to said second base and defining a fourth saw contact surface that is spaced apart from said third saw contact surface so as to define a second elongated cutting slot therebetween,
wherein said first base defines a first workpiece passage and a second workpiece passage that are spaced apart from each other so as to define a first workpiece space therebetween, said first workpiece space being positioned below said first elongated cutting slot, and
wherein said second base defines a third workpiece passage and a fourth workpiece passage that are spaced apart from each other so as to define a second workpiece space therebetween, said second workpiece space being positioned below said second elongated cutting slot,
wherein said first base defines a first cavity positioned below said first elongated cutting slot, said first cavity including said first workpiece space,
wherein said second base defines a second cavity positioned below said second elongated cutting slot, said second cavity including said second workpiece space,
wherein said first base includes a first passage surface and a second passage surface that are spaced apart from each other so as to define said first workpiece passage therebetween,
wherein said first base further includes a first guide wall portion positioned in said first cavity, said first guide wall portion defining a first guide surface portion,
