Abstract

A battery pack for a cordless power tool and a cordless power tool and battery pack combination includes the battery pack having a retention member that pivotally engages a retention member of the power tool and a latch system in which one of the battery pack and power tool has a ball and the other of the power tool and battery pack has a latch that engages the ball.

Claims

1. A cordless power tool and battery pack combination, comprising:

a. each of the power tool and battery pack having at least one retention member that pivotally engages the retention member of the other of the power tool and battery pack; and

b. a latch system including one of the power tool and the battery pack having a ball and the other of the power tool and battery pack having a latch that engages the ball.

2. The apparatus of claim 1 wherein the power tool has the ball and the battery pack has the latch.

4. The apparatus of claim 2 wherein the power tool'"'"'s retention member includes at least one hook extending toward the battery pack and the battery pack'"'"'s retention member includes at least one rod extending transversely across at least a portion of the battery pack.

5. The apparatus of claim 1 wherein the latch includes inner and outer sleeves that extend laterally across at least a portion of the one of the battery pack and power tool that includes the latch, each sleeve including a recess therein, a portion of the inner sleeve slidably received in a portion of the outer sleeve, the latch including at least one spring that urges the sleeves together to capture the ball between the sleeves in the recesses of the sleeves.

6. The apparatus of claim 5 wherein the ball includes a shaft and the shaft is captured in the recesses of the sleeves.

7. The apparatus of claim 5 wherein the latch includes at least one spring for each sleeve urging the recess in that sleeve toward the recess in the other sleeve.

8. The apparatus of claim 7 wherein each sleeve has an actuator member coupled to it, the actuator members, when pressed, moving the sleeves with respect to each other to open the latch.

9. The apparatus of claim 1 wherein the retention members are at generally a rear of the power tool and battery pack and the latch system is at generally a front of the power tool and battery pack.

3. The apparatus of claim 3 wherein the ball extends toward the battery pack from a bottom of a foot of the power tool.

10. A cordless power tool and battery pack combination, comprising:

a. each of the power tool and battery pack having at least one retention member that pivotally engages the retention member of the other of the power tool and battery pack; and

b. a latch system including the power tool having a ball extending from a bottom of a foot of the power tool and the battery pack having a latch that engages the ball, the latch including inner and outer sleeves that extend laterally across at least a portion of the battery pack, each sleeve including a recess therein, a portion of the inner sleeve slidably received in a portion of the outer sleeve, the latch including at least one spring for each sleeve, the springs urging the sleeves together so that the ball is captured between the recesses of the sleeves.

11. The apparatus of claim 10 wherein the ball includes a shaft and the shaft is captured in the recesses of the sleeve.

12. The apparatus of claim 10 wherein the retention members are at generally a rear of the power tool and battery pack and the latch system is at generally a front of the power tool and battery pack.

13. A battery pack for a power tool, comprising:

a. at least one retention member that pivotally engages a corresponding retention member of the power tool; and

b. a latch that engages a ball of the power tool.

14. The apparatus of claim 13 wherein the latch includes inner and outer sleeves that extend laterally across at least a portion of the battery pack, each sleeve including a recess therein, a portion of the inner sleeve slidably received in a portion of the outer sleeve, the latch including at least one spring for each sleeve, the springs urging the sleeves together so that the ball is captured between the recesses of the sleeves.

15. The apparatus of claim 14 wherein the retention member of the battery pack is at generally a rear of the battery pack and the latch is at generally a front of the battery pack.
