专利汇可以提供Hand held vibrator with flexible drive shaft专利检索，专利查询，专利分析的服务。并且A vibrator is disclosed which includes a flexible drive shaft and a connector at one end of the drive shaft for manually connecting and disconnecting the one end to a vacuum cleaner power source for rotating the drive shaft. An eccentric weight is releasably attached to the other end of the drive shaft for vibrating a handle. A first stop member is secured to the other end of the drive shaft, and a second stop member is secured to the handle for engaging the first stop member and preventing rotational movement of the drive shaft to permit manual removal of the eccentric weight. A cover is releasably secured to the handle to cover the eccentric weight by an annular groove on the cover extending through 360* and an annular lip on the handle extending through slightly more than 180*. The handle encapsulates the other end of the drive shaft to prevent abrupt bending thereof.，下面是Hand held vibrator with flexible drive shaft专利的具体信息内容。

权利要求

1. A vibrator comprising a flexible drive shaft, a flexible tubing means substantially encapsulating said flexible drive shaft, means at one end of said flexible drive shaft for manually selectively connecting and disconnecting said one end to a vacuum cleaner power means for rotating said flexible drive shaft, handle means at the other end of said drive shaft, said handle means including an axially extending hand receiving portion means for beiNg grasped by a human hand, said hand receiving portion means comprising solely an axially extending tubular reinforcing sleeve snugly encapsulating the end of said flexible tubing means adjacent said other end of said flexible drive shaft, eccentric weight means, first attachment means for manually releasably attaching said eccentric weight means to the other end of said flexible drive shaft for vibrating said handle means when said flexible drive shaft is rotated by said power means, cover means for at least partially encapsulating said eccentric weight means, second attachment means manually releasably attaching said cover means to said handle means and providing the sole means for preventing movement of said cover means relative to said handle means, and said second attachment means including continuous annular lip means of predetermined and nonextensible diameter extending through an arc of only slightly greater than 180* and an annular groove means for receiving said lip means, said annular lip means and annular groove means being disposed on said cover means and said handle means.

2. A vibrator as set forth in claim 1 wherein said continuous annular lip means extends fully into said groove means along the entire arcuate extent of said lip means.

3. A vibrator as set forth in claim 2 wherein said annular groove means extends through an arc of substantially 360*.

4. A vibrator as set forth in claim 3 wherein said annular lip means is on said handle means and said annular groove means is on said cover means.

5. A vibrator as set forth in claim 2 wherein said reinforcing sleeve provides the sole means for preventing abrupt bending of said last mentioned end of said flexible tubing and of said other end of said flexible drive shaft.

6. A vibrator as set forth in claim 5 including collar means covering the end of said flexible tubing means adjacent said one end of said flexible drive shaft for preventing abrupt bending of said last mentioned end of said flexible tubing means.

7. A vibrator as set forth in claim 2 wherein said first attachment means includes a first stop means secured to said other end of said flexible drive shaft, and a second stop means secured to said handle means and movable between a normally retracted position and a projected position in which said second stop means engages said first stop means to prevent rotational movement of said flexible drive shaft in at least one direction.

8. A vibrator as set forth in claim 7 wherein said second stop means is spring biased to said retracted position.
