Abstract
A multi-bit driver comprises a housing and a plurality of bit assemblies operatively retained within the housing. At least one of the bit assemblies has a base portion and a tool bit member removably and replaceably mountable on the base portion.
A bit chuck in the housing is for receiving each tool bit member singularly in torque transmitting relation, and includes a bit-receiving opening for permitting each tool bit member singularly to extend therethrough. The housing includes a substantially transparent forward portion that permits viewing of the tool bit members. An actuator extends from each bit assembly exteriorly to the housing for operative engagement by a user, for co-operative movement of the actuator means and the bit assembly between a retracted configuration, a forwardly extended in-use configuration.
A bit chuck in the housing is for receiving each tool bit member singularly in torque transmitting relation, and includes a bit-receiving opening for permitting each tool bit member singularly to extend therethrough. The housing includes a substantially transparent forward portion that permits viewing of the tool bit members. An actuator extends from each bit assembly exteriorly to the housing for operative engagement by a user, for co-operative movement of the actuator means and the bit assembly between a retracted configuration, a forwardly extended in-use configuration.
Claims (31)
1. A multi-bit driver comprising:
a housing;
a plurality of bit assemblies operatively retained within said housing, each bit assembly having a tool bit member, and wherein at least one of said plurality of bit assemblies has a base portion and a tool bit member removably and replaceably mountable on said base portion;
a bit chuck disposed at one end of said housing for receiving each tool bit member singularly in torque transmitting relation, and including a bit-receiving opening for permitting each tool bit member singularly to extend therethrough;
actuator means extending from each said bit assembly exteriorly to said housing for operative engagement by a user, for co-operative movement of said actuator means and said bit assembly between a retracted configuration, a forwardly extended in-use configuration whereat said bit assembly is positioned such that said tool bit member extends outwardly from said housing through said opening of said bit chuck, and back to said retracted configuration; and, means to retain said bit assemblies in said forwardly extended in-use configuration.
a housing;
a plurality of bit assemblies operatively retained within said housing, each bit assembly having a tool bit member, and wherein at least one of said plurality of bit assemblies has a base portion and a tool bit member removably and replaceably mountable on said base portion;
a bit chuck disposed at one end of said housing for receiving each tool bit member singularly in torque transmitting relation, and including a bit-receiving opening for permitting each tool bit member singularly to extend therethrough;
actuator means extending from each said bit assembly exteriorly to said housing for operative engagement by a user, for co-operative movement of said actuator means and said bit assembly between a retracted configuration, a forwardly extended in-use configuration whereat said bit assembly is positioned such that said tool bit member extends outwardly from said housing through said opening of said bit chuck, and back to said retracted configuration; and, means to retain said bit assemblies in said forwardly extended in-use configuration.
2. The multi-bit driver of claim 1, wherein said tool bit member is removably and replaceably mountable on said base portion of the respective bit assembly by means of a magnet.
3. The multi-bit driver of claim 2, wherein said magnet is mounted on said base portion.
4. The multi-bit driver of claim 2, wherein said magnet is mounted on said tool bit member.
5. The multi-bit driver of claim 1, wherein said base portion of each bit assembly comprises a magnetic material so as to retain said tool bit member in place on said base portion of the respective bit assembly.
6. The multi-bit driver of claim 1, wherein said tool bit member of each bit assembly comprises a magnetic material so as to retain said tool bit member in place on said base portion of the respective bit assembly.

13. The multi-bit driver of claim 12, wherein each actuator means comprises an actuator member.
14. The multi-bit driver of claim 13, wherein each actuator member is operatively attached in hinged relation to a co-operating bit assembly.
15. The multi-bit driver of claim 14, wherein each actuator member is operatively attached in pivoting relation to a co-operating bit assembly.
16. The multi-bit driver of claim 15, wherein each said actuator member comprises an attachment portion and a mounting portion connected together by a flexible connector portion.
17. The multi-bit driver of claim 16. wherein said flexible connector portion is resiliently flexible.
18. The multi-bit driver of claim 17, wherein each said flexible connector portion comprises a button portion disposed exteriorly to said housing.
19. The multi-bit driver of claim 12, wherein each actuator member comprises a unitary molded plastic piece.
20. The multi-bit driver of claim 12, wherein each said actuator member is mounted in slidable relation within a slot in said housing.
21. The multi-bit driver of claim 20, wherein each said slot is oriented longitudinally along said housing.
22. The multi-bit driver of claim 1, wherein said housing comprises a substantially transparent forward portion that permits viewing of said tool bit members.
23. The multi-bit driver of claim 22, wherein said substantially transparent forward portion comprises a cone portion extending from a central transition portion to said bit chuck.
24. The multi-bit driver of claim 23, wherein said housing tapers at said cone portion from said central transition portion to said bit chuck.
25. The multi-bit driver of claim 22, further comprising a rearward facing abutment surface disposed on said cone portion adjacent said bit chuck.
26. The multi-bit driver of claim 1, wherein said bit chuck is integrally formed within said housing.
27. The multi-bit driver of claim 1, wherein said housing further comprises a tool bit directing portion.
28. The multi-bit driver of claim 1, wherein said bit chuck aligns said tool bit along said longitudinal axis and said contact surface of said bit assembly is disposed in longitudinal force transmitting engagement against said abutment surface over said longitudinal axis with respect to said actuator means.
