Abstract

A jigsaw that uses a cutting blade generally includes a housing containing a motor activated by a trigger assembly. A blade storage compartment is recessed in the housing. A platform is provided in the blade storage compartment having a first edge that at least partially defines a first recess that extends further into the housing beyond the platform. A member is connected to the platform that produces a magnetic field that releasably secures the cutting blade to the platform. The magnetic field is configured to permit a user to tilt the cutting blade about the first edge of the platform into the first recess to overcome the magnetic field and remove the cutting blade from the storage compartment.

First claim

What is claimed is:

1. A jigsaw that uses cutting blades, the jigsaw comprising:
a housing containing a motor activated by a trigger assembly;
a blade storage compartment at least partially recessed in said housing;
a platform provided in said blade storage compartment, said platform having a first edge that at least partially defines a first recess and a second recess that is adjacent to said first recess, said first recess and said second recess extend further into said housing beyond said platform;
a member connected to said platform that produces a magnetic field that releasably secures a first cutting blade and a second cutting blade to said platform, wherein said magnetic field is configured to permit a user to tilt the first cutting blade about said first edge of said platform into said first recess to overcome said magnetic field and remove the first cutting blade from said storage compartment when the second cutting blade is secured to said platform.

2. The jigsaw of claim 1 further comprising a cover that when in a closed condition defines an outer surface that continues the general contours of the housing of the jigsaw around said cover.

3. The jigsaw of claim 1 , wherein said magnetic field is configured to permit said user to tilt the second cutting blade about said first edge into said second recess to overcome said magnetic field and remove the second cutting blade from said storage compartment.

4. The jigsaw of claim 1 further comprising a third recess in said blade storage compartment defined by a second edge on said platform opposite said first edge and one of said first and second recesses.

5. The jigsaw of claim 1 , wherein said member that produces said magnetic field is at least one magnet recessed in said platform and wherein the first cutting blade and the second cutting blade directly contacts said member.

6. The jigsaw of claim 1 further comprising a cover having a locking member deflectable by a hand operation between an engaged condition and a disengaged condition, in said engaged condition said locking member holds a portion of the blade storage compartment to secure said cover in a closed position, in said disengaged condition said locking member is deflected to permit opening of said cover.

7. The jigsaw of claim 1 further comprising a cover that opens and closes along an axis of rotation that is generally parallel to a cutting direction of the jigsaw.

8. The jigsaw of claim 7 , wherein said cover in an open condition swings toward a shoe member so that said cover extends laterally from said blade storage compartment.

9. The jigsaw of claim 8 , wherein said cover establishes a concave shape operable to hold an item that falls from said blade storage compartment.

10. The jigsaw of claim 1 further comprising a cover that can be secured to said blade storage compartment in a closed condition, wherein said cover is made of a material that at least partially permits a user to determine contents of said blade storage compartment.

11. The jigsaw of claim 1 further comprising
a reciprocating shaft connected to said motor that extends through said housing toward a cutting area;
a blade guard member that defines a left arm portion, a right arm portion and a base portion therebetween, wherein said blade guard member extends from said housing in front of said reciprocating shaft and toward said cutting area;
a fascia connected to said housing, said fascia defining a left fascia half that connects to a left half shell of said housing and a right fascia half that connects to a right half shell of said housing, wherein said left arm portion of said blade guard member is an integral extension of said left fascia half and said right arm portion is an integral extension of said right fascia half; and
said base portion being split into a left portion and a right portion, wherein said left portion of said base portion extends from said left arm portion of said blade guard member and said right portion of said base portion extends from said right arm portion of said blade guard member and wherein said left portion and said right portion of said base portion are fastened together in an abutting relationship.

12. The jigsaw of claim 1 , further comprising
a fan connected to said motor;
a flexible member disposed in said housing through which a power cord is disposed, wherein said flexible member is configured to permit said power cord and portions of said flexible member to flex relative to said housing; and
at least one cooling passageway formed through said flexible member, wherein said fan establishes an airflow through said at least one cooling passageway, wherein said at least one cooling passageway extends through said flexible member along a longitudinal axis that is substantially parallel to a longitudinal axis of a portion of said power cord that extends through said flexible member.

13. A jigsaw for cutting a workpiece with a cutting blade, the jigsaw comprising:
a housing containing a motor activated by a trigger assembly, wherein said housing defines a left half shell and a right half shell;
a shoe member connected to said housing;
a reciprocating shaft connected to said motor that extends through said housing toward a cutting area, said reciprocating shaft operable to hold the cutting blade;
a blade guard member including a left arm portion, a right arm portion and a base portion therebetween, wherein said blade guard member extends from said housing in front of said reciprocating shaft and toward said cutting area to terminate proximate said shoe member;
said left arm portion extends from said left half shell;
said right arm portion extends from said right half shell; and
said base portion being split into a left portion and a right portion, wherein said left portion of said base portion extends from said left arm portion of said blade guard member and said right portion of said base portion extends from said right arm portion of said blade guard member;
the jigsaw further comprising a blade storage compartment recessed in said housing;
a platform provided in said blade storage compartment having a first edge that at least partially defines a first recess that extends further into said housing beyond said platform; and
a member connected to said platform that produces a magnetic field that releasably secures a cutting blade to said platform, wherein said magnetic field is configured to permit a user to tilt said cutting blade about said first edge into said first recess to overcome said magnetic field and remove said cutting blade from said storage compartment.

14. The jigsaw of claim 13 , wherein said left arm portion is an integral extension of said left half shell and wherein said right arm portion is an integral extension of said right half shell.

15. The jigsaw of claim 13 , wherein said left portion and said right portion of said base portion are fastened together in an abutting relationship.

16. The jigsaw of claim 13 further comprising a fascia member connected to said housing of the jigsaw, said fascia member defining a left fascia half shell that connects to said left half shell of said housing and a right fascia half shell that connects to said right half shell of said housing, wherein said left arm portion of said blade guard member is an integral extension of said left fascia half shell and said right arm portion is an integral extension of said right fascia half shell.

17. The jigsaw of claim 13 , wherein said magnetic field is configured to permit said user to tilt a second cutting blade about said first edge into a s
