Abstract
Abstract A latching mechanism is described for removably mounting a handlebar to a lawn and yard implement. Also described is 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: 11
Claim 1
Independent Claim
93 words
A handlebar latching mechanism for releasably attaching a handlebar to a lawn and yarn implement, comprising: a first pair of slotted brackets adapted to be fixed to the implement; a second pair of slotted brackets adpated to be fixed to the handlebar; wherein the first and second slotted brackets mate in a releasable interlocking relationship; wherein each bracket of one pair includes a pin projecting therefrom to be slidably received by a matching slot of a mating bracket of the opposed pair; and selectively releasable detent means for locking the mating brackets together.
Claim 2
Dependent Claim
93 words
A handlebar latching mechanism for releasably attaching a handlebar to a lawn and yarn implement, comprising: a first pair of slotted brackets adapted to be fixed to the implement; a second pair of slotted brackets adpated to be fixed to the handlebar; wherein the first and second slotted brackets mate in a releasable interlocking relationship; wherein each bracket of one pair includes a pin projecting therefrom to be slidably received by a matching slot of a mating bracket of the opposed pair; and selectively releasable detent means for locking the mating brackets together.
Claim 3
Dependent Claim
84 words
The handlebar latching mechanism as set out in claim 1 wherein the detent means comprises: a matching pair of closed slots in the second pair of brackets; said closed slots being substantially perpendicular to the remaining bracket slots of the first and second bracket pairs; 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.
Claim 4
Dependent Claim
35 words
The handlebar latching mechanism as set out by claim 2 further comprising spring means for urging the elongated rod into the open rod receiving indentations when the first and second slotted brackets are mated together.
Claim 5
Dependent Claim
55 words
The handlebar latching mechanism as set out by claim 1 wherein the matching slots of said first pair of slotted brackets are formed as open slots facing rearwardly away from the associated implement and the matching slots of said second pair of slotted brackets are formed as open slots facing forwardly toward the associated implement.
Claim 6
Dependent Claim
66 words
The handlebar latching mechanism as set out by claim 1 wherein the pins on the first bracket pair project from their respective brackets in opposite directions to be slidably received within slots of the second bracket pair and wherein the pins on the second bracket pair project oppositely both relative to each other and individually with respect to the corresponding pins of the first bracket pair.
Claim 7
Dependent Claim
68 words
The handlebar latching mechanism as set out by claim 1 wherein the matching slots of said first pair of slotted brackets are formed as open slots facing rearwardly away from the associated implement and wherein the matching slots of said second pair of slotted brackets are formed as open slots facing forwardly toward the associated implement, the open slots of both bracket pairs being parallel along their lengths.
Claim 8
Dependent Claim
84 words
The handlebar latching mechanism as set out in claim 6 wherein the detent means comprises: a matching pair of closed slots in the second pair of brackets; said closed slots being substantially perpendicular to the remaining bracket slots of the first and second bracket pairs; 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.
Claim 9
Dependent Claim
63 words
The handlebar latching mechanism as set out by claim 6 wherein the pins of the first bracket pair are spaced forwardly toward the associated implement in relation to the open slots of the first bracket pair and the pins of the second bracket pair are spaced rearwardly away from the associated implement in relation to the open slots of the second bracket pair.
Claim 10
Dependent Claim
84 words
The handlebar latching mechanism as set out in claim 8 wherein the detent means comprises: a matching pair of closed slots in the second pair of brackets; said closed slots being substantially perpendicular to the remaining bracket slots of the first and second bracket pairs; 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.
Claim 11
Dependent Claim
35 words
The handlebar latching mechanism as set out by claim 9 further comprising spring means for urging the elongated rod into the open rod receiving indentations when the first and second slotted brackets are mated together.
