Abstract
Abstract A powered lawn and yard implement for removing trash or like material from a lawn or yard and discharging the material into a wheeled pushcart. The implement includes a wheel supported housing to which the wheeled pushcart is releasably connected. A chute assembly directs trash from the housing into an upwardly open bin of the pushcart. The pushcart includes an elongated support roller and a pushbar assembly that facilitate independent movement of the pushcart assembly when detached from the housing. The housing includes a latching mechanism that may be operated from one side of the housing to secure or release the pushcart relative to the housing. Also associated with the latching mechanism is a deflector assembly that operates in response to operation of the latching assembly to open or close the discharge chute leading to the open bin. When the pushcart is detached from the housing, the deflector mechanism is located in position to prevent discharge of material through the chute. When the cart is attached to the housing, the latch mechanism and associated deflector mechanism are moved to positions wherein the latch mechanism releasably locks the pushcart to the housing and the deflector mechanism opens to become an integral part of the chute means, guiding discharged trash into the attached cart.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
93 words
A lawn and yard implement, comprising: a wheel supported housing; ground working means on the housing for forcibly removing trash from the ground surface and projecting it outwardly from the housing; a wheel supported pushcart having an open trash receiving bin and a pushbar mounted thereto; latching means for releasably fixing the pushcart to the housing; chute means for guiding the projected trash from the housing into the pushcart bin; and deflector means associated with the latching means for blocking passage of the trash from the housing when the pushcart is detached therefrom.
Claim 2
Dependent Claim
93 words
A lawn and yard implement, comprising: a wheel supported housing; ground working means on the housing for forcibly removing trash from the ground surface and projecting it outwardly from the housing; a wheel supported pushcart having an open trash receiving bin and a pushbar mounted thereto; latching means for releasably fixing the pushcart to the housing; chute means for guiding the projected trash from the housing into the pushcart bin; and deflector means associated with the latching means for blocking passage of the trash from the housing when the pushcart is detached therefrom.
Claim 3
Dependent Claim
34 words
The implement as set out by claim 1 wherein the chute means includes a shroud member for at least partially covering the open pushcart bin when the pushcart is releasably fixed to the housing.
Claim 4
Dependent Claim
29 words
The implement as set out by claim 2 further comprising a flexible flap fixed along an edge of the shroud member to depend therefrom into the open pushcart bin.
Claim 5
Dependent Claim
58 words
The implement as set out by claim 1 wherein the deflector means is comprised of a plate pivotably mounted within the housing adjacent the chute means for movement between an open position wherein the plate forms an integral portion of the chute means and a closed position wherein the plate obstructs passage of trash through the chute means.
Claim 6
Dependent Claim
31 words
The implement as set out by claim 4 wherein the latching means includes a deflector lock assembly associated with the latching means for releasably locking the plate in the closed position.
Claim 7
Dependent Claim
57 words
The implement as set out by claim 4 wherein the latching means includes catch mechanisms on opposite sides of the housing to releasably receive complementary locking members on the pushcart and wherein the catch mechanisms are operatively interconnected across the housing by the deflector means such that the catch mechanisms and deflector means may be operated simultaneously.
Claim 8
Dependent Claim
38 words
The implement as set out by claim 1 wherein the pushbar is extensibly mounted to the pushcart and is adjustable thereon from a position closely adjacent the pushcart bin to an extended position spaced outward of the bin.
Claim 9
Dependent Claim
126 words
A lawn and yard implement, comprising: a wheel supported housing; ground working means on the housing for forcibly removing trash from the ground surface and projecting it outwardly from the housing; a wheel supported pushcart having an open trash receiving bin and a pushbar mounted thereto; latching means for releasably fixing the pushcart to the housing; wherein the latching means includes two catch mechanisms, one on each side of the housing for releasably receiving two complementary locking members of the pushcart; chute means for guiding the projected trash from the housing into the pushcart bin; and manually operable release means operatively associated with the catch mechanisms for selectively operating both catch mechanisms simultaneously to release the locking members and thereby disengage the pushcart from the housing.
Claim 10
Dependent Claim
126 words
A lawn and yard implement, comprising: a wheel supported housing; ground working means on the housing for forcibly removing trash from the ground surface and projecting it outwardly from the housing; a wheel supported pushcart having an open trash receiving bin and a pushbar mounted thereto; latching means for releasably fixing the pushcart to the housing; wherein the latching means includes two catch mechanisms, one on each side of the housing for releasably receiving two complementary locking members of the pushcart; chute means for guiding the projected trash from the housing into the pushcart bin; and manually operable release means operatively associated with the catch mechanisms for selectively operating both catch mechanisms simultaneously to release the locking members and thereby disengage the pushcart from the housing.
Claim 11
Dependent Claim
89 words
The implement as set out by claim 8 further comprising handlebar latching means that includes a first pair of slotted brackets rigidly fixed to the housing and a complementary second pair of slotted brackets fixed to the handlebar assembly for mating engagement with respective brackets of the first pair; with each bracket of both pairs having a pin projecting therefrom to be slidably received by the slot of a mating bracket of the opposite pair; and further comprising a selectively releasable detent means for locking the mating brackets together.
Claim 12
Dependent Claim
91 words
The implement as set out by claim 9 wherein the detent means comprises: a matching pair of closed slots in the second pair of brackets, said slots being substantially perpendicular to the remaining bracket slots; an elongated rod extending between the brackets of the second pair and being received within the matching pair of closed slots for movement within the confines thereof; and open rod receiving indentations in the brackets of the first pair, said closed slots being substantially perpendicular to the remaining slots of the first and second bracket pairs.
Claim 13
Dependent Claim
140 words
A lawn and yard implement, comprising: a wheel supported housing; ground working means on the housing for forcibly removing trash from the ground surface and projecting it outwardly from the housing; a wheel supported pushcart having an open trash receiving bin and a pushbar mounted thereto; latching means for releasably fixing the pushcart to the housing; chute means for guiding the projected trash from the housing into the pushcart bin; a handlebar assembly; handlebar latching means releasably mounting the handlebar assembly to the housing; and a shroud member on the handlebar assembly for covering the open pushcart bin when the pushcart is releasably fixed to the housing; wherein the shroud member is movably mounted to the handlebar assembly and includes freely rotatable rollers thereon for loosely engaging the pushcart bin to thereby movably support the shroud member on the bin.
