Abstract
This disclosure relates to a raking device, and in some implementations, a detachable rake head for raking sand traps and its method of use. The raking device may be configured to be releasably attached to a supporting handle (e.g., a broom handle, 5 golf club, golf ball retriever, or other rod-typed structure).
Claims16
A rake device comprising:
- a rake body having a lock collar slot;
- a plurality of extendable rake heads hingedly coupled to the rake body and rotatable from a first position substantially parallel to a major axis of the rake body to a second position substantially perpendicular to the major axis of the rake body;
- wherein the extendable rake heads comprise a plurality of raking tine apertures and a plurality of extendable raking tines, wherein the extendable raking tines are configured to extend through the plurality of raking tine apertures;
- a rotatable lock collar coupled to the extendable rake heads and positioned to mate with the lock collar slot responsive to said rotation of the extendable rake heads to the second position;
- an extension button on the rake body mechanically coupled to a coil spring to actuate the extendable rake heads from the first position to the second position;
- and a rotational cable mechanically coupled to the extension button so as to shift the extendable raking tines within the plurality of raking tine apertures from a retracted position to an extended position in response to movement of the extendable rake heads from the first position to the second position.

A method of raking a granular material comprising:
- inserting a supporting handle into a detachable rake device, the rake device having a rake body with a lock collar slot;
- extending a plurality of extendable rake heads hingedly coupled to the rake body from a first position substantially parallel to a major axis of the rake body to a second position substantially perpendicular to the major axis of the rake body, wherein the step of extending the plurality of extendable rake heads comprises depressing an extension button on the rake body to actuate the extendable rake heads from the first position to the second position
- engaging a rotatable lock collar coupled to the extendable rake heads with the lock collar slot in response to said rotation of the extendable rake heads to the second position;
- extending a plurality of extendable raking tines through a plurality of raking tine apertures on the extendable rake heads, wherein the step of extending the plurality of extendable raking tines comprises a rotational cable mechanically coupled to the extension button to shift the extendable raking tines relative to the plurality of raking tine apertures from a retracted position to an extended position in response to movement of the extendable rake heads from the first position to the second position;
- and
- contacting the extendable raking tines to the granular material.
