Abstract
A first component part (42) for a power tool has a mounting spigot (90) with a channel (239) therein and a second component part (10) of the power tool has a spigot receiving portion (54) with a rib (101) co-operable with the channel. The first component part includes a cylindrical projection with a chamfered edge (250) and the second component part includes a detent. In a first step in coupling the components parts, the channel in the mounting spigot is aligned with the co-operable rib on the spigot receiving portion. Subsequent steps include engaging the further rib of the spigot receiving portion with a channel on a side wall and finally, urging the chamfered edge past the detent.
Claims16
A method of coupling a first component part and a second component part of a power tool;
- the first component part having a mounting spigot with at least one channel formed therein and a generally cylindrical projection formed on the mounting spigot, the generally cylindrical projection including a side wall having a chamfered edge and wherein the side wall includes at least one channel parallel to an axis of the generally cylindrical member;
- the second component part having a spigot-receiving portion including at least one rib co-operable with the at least one channel formed in the mounting spigot, and a generally cylindrical housing member co-operable with the generally cylindrical projection of the first component part, the spigot receiving portion including at least one further rib co-operable with the at least one channel in the side wall of the first component part, the second component part further including a detent, the method comprising the steps of:
- aligning the at least one channel in the mounting spigot with the at least one co-operable rib on the spigot receiving portion;
- coupling the housing member with the cylindrical projection;
- engaging the further at least one rib of the spigot-receiving portion with the at least one channel of the side wall;
- and
- urging the chamfered edge past the detent.
A power tool comprising:
- a first component part having a mounting spigot with at least one channel formed therein and a generally cylindrical projection formed on the mounting spigot, the generally cylindrical projection including a side wall having a chamfered edge and at least one channel parallel to an axis of the generally cylindrical member;
- and
- a second component part having a spigot-receiving portion including at least one rib aligned with the at least one channel formed in the mounting spigot, and a generally cylindrical housing member coupled with the generally cylindrical projection of the first component part, the spigot receiving portion including at least one further rib engaged with the at least one channel in the, side wall of the first component part, the second component part further including a detent cooperating with the chamfered edge.
