Abstract

Abstract A rake head for attachment to a handle such as a golf club shaft has a mounting bracket that removably and replaceably seats on the club shaft and which carries a pair of rake blades. The rake blades are rotatable between an in-line, deployed position and a folded, collapsed position. Abutments limit the rotation of the rake blades, and a holding structure maintains the rake blades in the deployed position.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 112 words
A rake head for removably and replaceably attaching on a handle-forming shaft, said rake head comprising, in combination A. a mounting bracket (1) having a slotted shaft-engageable collar with a central axis and arranged for said attachment with the shaft extending along said axis, and (2) having first and second oppositely-directing blade-mounting members, and B. first and second rake blades, each with plural rake teeth, and each mounted to the same-numbered mounting member and rotatable relative thereto between a deployed position, where said blades are aligned one with another along a second axis extending transversely to said collar axis, and a collapsed position rotated substantially a quarter turn from said deployed position.
Claim 2
Dependent Claim 112 words
A rake head for removably and replaceably attaching on a handle-forming shaft, said rake head comprising, in combination A. a mounting bracket (1) having a slotted shaft-engageable collar with a central axis and arranged for said attachment with the shaft extending along said axis, and (2) having first and second oppositely-directing blade-mounting members, and B. first and second rake blades, each with plural rake teeth, and each mounted to the same-numbered mounting member and rotatable relative thereto between a deployed position, where said blades are aligned one with another along a second axis extending transversely to said collar axis, and a collapsed position rotated substantially a quarter turn from said deployed position.
Claim 3
Dependent Claim 39 words
A rake head as defined in claim 1 in which said blade-mounting members are disposed for orienting said rake blades, when in said collapsed position, side-by-side with one another, and extending at least partially longitudinal with said collar axis.
Claim 4
Dependent Claim 31 words
A rake head as defined in claim 1 further comprising holding means cooperating with said rake blades and said mounting members for releasably holding said rake blades in said deployed position.
Claim 5
Dependent Claim 33 words
A rake head as defined in claim 3 in which said holding means includes means for providing frictional engagement between said rake blades and said mounting members to provide said releasable holding action.
Claim 6
Dependent Claim 31 words
A rake head as defined in claim 1 further comprising detent means cooperating with said mounting members and said rake blades for releasably holding said rake blades in said deployed position.
Claim 7
Dependent Claim 34 words
A rake head as defined in claim 1 further comprising stop means fixed relative to said mounting bracket and engageable with said rake blades to limit rotation to at least one of said positions.
Claim 8
Dependent Claim 44 words
A rake head as defined in claim 6 in which said stop means includes first and second shoulder means disposed on said mounting bracket for abutment with said first and second rake blades respectively upon rotation of said rake blades to said one position.
Claim 9
Dependent Claim 58 words
A rake head according to claim 6 in which said stop means includes first and second abutment means disposed on said mounting bracket for abutment with said same-numbered rake blade upon pivotal motion thereof to both said deployed position and to said collapsed position, for limiting the pivotal movement of each rake blade into each of said positions.
Claim 10
Dependent Claim 156 words
A collapsible rake head for removably and replaceably deployably detaching on a golf club shaft and thereby suitable for raking golf course sand traps, said collapsible rake head comprising, in combination A. a mounting bracket (1) having a slotted shaft-engageable tubular collar having a central axis and arranged for said deployable attachment with the shaft extending along said axis, (2) having first and second oppositely-directed blade-mounting tabs disposed symmetrically to one another relative to said collar, and (3) having a bridging member interconnecting said mounting tabs and said collar and providing stepped shoulder surfaces adjacent the interconnection thereof with each said mounting tab, and B. first and second rake blades, each mounted to the same-numbered mounting tab and rotatable relative thereto between a deployed position, where said blades are aligned one with another along a second axis extending transversely to said collar axis, and a collapsed position rotated substantially a quarter turn from the deployed position.
Claim 11
Dependent Claim 156 words
A collapsible rake head for removably and replaceably deployably detaching on a golf club shaft and thereby suitable for raking golf course sand traps, said collapsible rake head comprising, in combination A. a mounting bracket (1) having a slotted shaft-engageable tubular collar having a central axis and arranged for said deployable attachment with the shaft extending along said axis, (2) having first and second oppositely-directed blade-mounting tabs disposed symmetrically to one another relative to said collar, and (3) having a bridging member interconnecting said mounting tabs and said collar and providing stepped shoulder surfaces adjacent the interconnection thereof with each said mounting tab, and B. first and second rake blades, each mounted to the same-numbered mounting tab and rotatable relative thereto between a deployed position, where said blades are aligned one with another along a second axis extending transversely to said collar axis, and a collapsed position rotated substantially a quarter turn from the deployed position.
Claim 12
Dependent Claim 39 words
A rake head as defined in claim 9 further comprising a pair of stop edges on each rake blade, each stop edge being disposed for abutment against one shoulder upon rotation of the blade to one of said positions.
Claim 13
Dependent Claim 36 words
A rake head as defined in claim 9 further comprising interengageable means on each rake blade and on each mounting tab for resisting dislodgement of said rake blades from said deployed position toward said collapsed position.
