Abstract
A power tool generally includes a housing and a motor assembly connected to a transmission assembly. The motor assembly and the transmission assembly are secured against rotation in the housing. A plurality of protrusions extends from a component of the transmission assembly. The power tool further includes an output spindle and a spindle lock assembly that connects the output spindle to the transmission assembly. The spindle lock assembly includes an anvil, an outer ring member and a plurality of roller members. The roller members and the protrusions are disposed between the anvil and the outer ring member. An indicator member extends from the outer ring member. A compliant member connects the outer ring member to an interior portion of the housing. A scale is connected to an exterior portion of the housing, wherein the indicator member moves relative to the scale to indicate a value of torque at the output spindle.
Claims
AMENDED CLAIMS received by the International Bureau on 5 September 2008 (05/09/2008)
1 - 10. CANCELED
11. A power tool comprising: a housing; a motor assembly connected to a transmission assembly, wherein said motor assembly and said transmission assembly are secured against rotation in the housing; a plurality of projections that extends from a component of said transmission assembly; an output spindle; a spindle lock assembly that connects said output spindle to said transmission assembly, said spindle lock assembly includes an anvil, an outer ring member and a plurality of roller members, wherein said roller members and said projections are disposed between said anvil and said outer ring member; an indicator member connected to said outer ring member, said indicator member having a portion that is disposed outside of said housing; a compliant member that connects said outer ring member to an interior portion of said housing; a scale established on an exterior portion of said housing, wherein said portion of said indicator member is disposed over said scale and said portion of said indicator member moves relative to said scale to indicate a value of torque at said output spindle.
12. The power tool of Claim 11 , wherein said compliant member is a spring member with successive coils that wrap around a portion of said transmission assembly.
13. The power tool of Claim 11 , wherein said compliant member is a spring member with successive coils that are disposed between said transmission assembly and said output spindle.
14. The power tool of Claim 11 , wherein said component of said transmission assembly from which said plurality of projection extends includes a planet carrier of a planetary transmission.
15. Thθ power tool of Claim 11 , wherein said compliant member is a spring member, wherein said spring member is in a compressed state regardless of an angular position of said outer ring member.
16. A power tool comprising: a housing that contains a transmission assembly that connects an output spindle to a motor assembly; a compliant member that connects one of said transmission assembly • and said motor assembly to said housing; a trigger assembly connected to said housing, said trigger assembly activates said motor assembly when said trigger assembly is in a retracted condition; an indicator member that extends from one of said motor assembly and said transmission assembly and terminates above an exterior portion of said housing, said indicator member having a portion that is disposed outside of said housing; a scale established on said exterior portion of said housing beneath said portion of said indicator member, wherein said portion of said indicator member moves relative to said scale to indicate a value of torque at said output spindle.
17. The power tool of Claim 16, further comprising; a plurality of projections that extends from a component of said transmission assembly; a spindle lock assembly that connects said output spindle to said transmission assembly, wherein said spindle lock assembly includes an anvil, an outer ring member and a plurality of roller members, wherein said roller members and said projections are disposed between said anvil and said outer ring member,
15
wherein said outer ring member is secured to said housing.
18. The power tool of Claim 17, wherein said component of said transmission assembly from which said plurality of projection extends includes a planet carrier member.
19. The power tool of Claim 16, wherein said transmission assembly includes one of a planetary transmission and a parallel shaft spur gear transmission.
20. The power tool of Claim 16, wherein said compliant member is a spring member, wherein said spring member is in a compressed state regardless of an angular position of said outer ring member.
21. A method comprising: rotating a housing of a power tool to rotate an output spindle of the power tool; moving a spindle lock assembly to a lock condition; compressing a spring member between the spindle lock assembly and the housing; moving an indicator member connected to the spindle lock assembly relative to the housing; indicating value of torque applied to the output spindle on an external scale on the housing with a portion of the indicator member that extends over the housing on which the external scale is established.
22. The method of Claim 21, wherein the compressing of the spring member between the spindle lock assembly and the housing includes moving an outer ring member a distance that is proportional to the torque applied to the output spindle.
23. The method of Claim 21 further comprising: further rotating the housing of the power tool to increase the torque applied to the output spindle of the power tool, wherein said portion of the indicator member moves relative to the external scale established on the housing to reflect the increase in the torque applied to the output spindle.
