Abstract
A rake system is provided which includes a pair of rake-like arm extensions, each having a multi-tine rake head mounted on an improved ergonomic handle. The handle employs an extension shaft which attaches to the rake head, and a grip shaft which projects from the extension shaft at an acute angle so as to define an angled user handhold. A forearm brace extends between the extension shaft and grip shaft, the forearm brace being configured to engage the back side of the user's forearm so as to oppose pivot of the rake head about the user handhold when debris is picked up. The extension and grip shafts preferably are configured to run substantially parallel to one another in a leverage region which extends from corresponding alignment bends of the shafts to the handle's proximal end.
Claims19
A rake system comprising:
- a rake head;
- a handle including an elongate extension shaft secured to said rake head and an elongate grip shaft projecting proximally from said extension shaft at an acute angle, thereby defining a user handhold which is angled relative to said extension shaft;
- and
- a forearm brace extending between said extension shaft and said grip shaft, said forearm brace opposing pivot of said rake head about said user handhold.
A rake system comprising:
- a left arm extension including a first multi-fine rake head, a generally Y-shaped left arm handle and a left forearm brace, said left arm handle having a first elongate extension shaft which secures to said first rake head and a first elongate grip shaft which projects proximally from said first extension shaft at an acute angle to define a handhold for a user's left hand, said left forearm brace extending between said first extension shaft and said first grip shaft to engage the user's left arm, thereby opposing pivot of said first rake head about said left arm handhold;
- and
- a right arm extension including a second multi-tine rake head, a generally Y-shaped right arm handle and a right forearm brace, said right handle having a second elongate extension shaft which secures to said second rake head and a second elongate grip shaft which projects proximally from said second extension shaft at an acute angle to define a handhold for a users right hand, said right forearm brace extending between said second extension shaft and said second grip shaft to engage the user's right arm, opposing pivot of said second rake head about said right arm handhold.
A rake system for use in gathering debris, picking up the debris, and delivering the debris to a collapsible receptacle, said rake system comprising:
- a left arm extension including a first multi-tine rake head, a generally Y-shaped left arm handle and a left forearm brace, said left arm handle having a first elongate extension shaft which secures to said first rake head and a first elongate grip shaft which projects proximally from said first extension shaft at an acute angle of approximately 60-degrees to define a handhold for a user's left hand, said first extension shaft defining a first extension shaft alignment bend of approximately 15-degrees toward said first grip shaft and said first grip shaft defining a first grip shaft alignment bend of approximately 45-degrees toward said first extension shaft, said first extension shaft and said first grip shaft thus being configured to run substantially parallel to one another in a first leverage region which is proximate to said left handle alignment bends, said left forearm brace extending between said first extension shaft and said first grip shaft in the first leverage region to engage the user's left arm, thereby opposing pivot of said first rake head about said left arm handhold;
- a right arm extension including a second multi-tine rake head, a generally Y-shaped right arm handle and a right forearm brace, said right handle having a second elongate extension shaft which secures to said second rake head and a second elongate grip shaft which projects proximally from said second extension shall at an acute angle of approximately 60-degrees to define a handhold for a user's right hand, said second extension shaft defining a second extension shaft alignment bend of approximately 15-degrees toward said second grip shalt and said second grip shaft defining a second grip shaft alignment bend of approximately 45-degrees toward said second extension shaft, said second extension shaft and said second grip shaft thus being configured to run substantially parallel to one another in a second leverage region which is proximate to said right handle alignment bends, said right forearm brace extending between said second extension shaft and said second grip shaft in the first leverage region to engage the user's right arm, thereby opposing pivot of said second rake head about said right arm handhold;
- and
- a resilient panel biased toward an orientation wherein said panel is planar, but being configurable in a generally cylindrical orientation for insertion into the collapsible receptacle, thereby providing increased structural integrity to the receptacle.
