Abstract
A brush to handle connector for a push broom is provided for adjustably attaching the handle to the brush head in such a manner as to allow user of the push broom to twist the brush head in various directions and retain it thereby allowing the user to fit the brush head into narrow spaces by changing the angle between the brush head and the handle.
Claims6
A brush to handle connector for a push broom having a brush head with extending bristles and an elongated handle, said connector comprising:
- (a) means for adjustably attaching the handle to the brush head in such a manner as to allow user of the push broom to twist the brush head in various directions, thereby allowing the user to fit the brush head into narrow spaces and by changing the angle between the brush head and the handle to use the push broom more easily and more efficiently than with the usual rigid connection;
- and
- (b) means for retaining the brush head to said adjustably attaching means for angular adjustment, wherein said adjustably attaching means includes:
- (c) a sleeve secured to lower end of the handle;
- (d) a lug having a threaded aperture, said lug transversly affixed to lower end of said sleeve in such a manner that said sleeve extends angularly therefrom;
- and
- (e) a bolt having an annular groove in a threaded shaft which extends transversely through the brush head and through the threaded aperture in said lug.
