Abstract
A removable working tool assembly that can be used with a power driven tool having a drive shaft. The removable working tool assembly includes a drive member which can operably connected to the drive shaft and a support member having a tool surface. One of the drive and support members defines a male connection mechanism while the other one of the members defines a female connection mechanism such that the members can be simply connected and disconnected without the need for tools or any other fastener elements. This allows various support members to be easily changed to facilitate the use of different tool surfaces such as sanders, grinders, scrapers or the like.
Claims23
A removable working tool assembly to be used with a power driven tool having a drive shaft, the removable working tool assembly comprising:
- a drive member which can be operably connected to the drive shaft of the power tool;
- and
- a support member having a tool surface;
- and
- one of the drive and support members defining a male connection mechanism and the other one of the drive and support members defining a female connection mechanism such that the male connection mechanism may operably engage the female connection mechanism without the need for tools or any other fastener elements, allowing the support member to be easily disconnected and reconnected to the drive member;
- wherein one of the male and female connection mechanisms has a raised portion and the other one of the male and female connection mechanisms has a depression such that the raised portion and the depression engage when the male connection mechanism engages the female connection mechanism thereby preventing the male connection mechanism from being disengaged from the female connection mechanism during use.
A removable working tool assembly to be used with a power driven tool having a drive shaft, the removable working tool assembly comprising:
- a drive member which can be operably connected to the drive shaft of the power tool;
- and
- a support member having a tool surface;
- and
- one of the drive and support members defining a male connection mechanism and the other one of the drive and support members defining a female connection mechanism such that the male connection mechanism may operably engage the female connection mechanism without the need for tools or any other fastener elements, allowing the support member to be easily disconnected and reconnected to the drive member;
- wherein the drive shaft of the power tool has a center axis which, if extended after the drive member has been operably connected to the drive shaft and the support member has been operably connected to the drive member, does not intersect the central region of the tool surface of the support member.
A removable working tool assembly to be used with a power tool having a drive shaft, the removable working tool assembly comprising:
- a drive member having a drive end operably connected to the drive shaft of the power tool and a first connection end spaced apart from the drive shaft of the power abrasive tool;
- a support member having a tool surface and a second connection end;
- and
- one of the first and second connection ends defining a male connection mechanism and the other one of the first and second connection ends defining a female connection mechanism such that the male connection mechanism may operably engage the female connection mechanism without the need for tools or any other fastener elements, allowing the support member to be easily disconnected and reconnected to the drive member.
A removable working tool assembly to be used with a power tool having a drive shaft and a dust collection system, the removable working tool assembly comprising:
- a drive member which can be operably connected to the drive shaft of the power tool and which defines a drive member exit opening which may be operably connected to the dust collection system, a drive member collection opening, and a drive member conduit connecting the drive member collection opening to the drive member exit opening;
- a support member having a tool surface and a periphery surface which defines dust intake openings, the support member further defining a support exit opening and support conduits connecting the dust intake openings to the support exit opening;
- and
- one of the drive and support members defining a male connection mechanism and the other one of the drive and support members defining a female connection mechanism such that the male connection mechanism may operably engage the female connection mechanism without the need for tools or any other fastener elements with the result being that the support exit opening communicates with the drive member collection opening and which allows the support member to be easily disconnected and reconnected to the drive member;
- wherein the drive shaft of the power tool has a center axis which, if extended after the drive member has been operably connected to the drive shaft and the support member has been operably connected to the drive member, does not intersect the central region of the tool surface of the support member.
A removable working tool assembly to be used with a power tool having a drive shaft and a dust collection system, the removable working tool assembly comprising:
- a drive member which can be operably connected to the drive shaft of the power tool and which defines a drive member exit opening which may be operably connected to the dust collection system, a drive member collection opening, and a drive member conduit connecting the drive member collection opening to the drive member exit opening;
- a support member having a tool surface and a periphery surface which defines dust intake openings, the support member further defining a support exit opening and support conduits connecting the dust intake openings to the support exit opening;
- one of the drive and support members defining a male connection mechanism and the other one of the drive and support members defining a female connection mechanism such that the male connection mechanism may operably engage the female connection mechanism without the need for tools or any other fastener elements with the result being that the support exit opening communicates with the drive member collection opening and which allows the support member to be easily disconnected and reconnected to the drive member;
- and
- wherein the drive member extends laterally outward from the drive shaft after being operably connected to the drive shaft such that the engagement between the male connection mechanism and the female connection mechanism is spaced apart from the drive shaft.
