Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
203 words
A mounting apparatus for releasably mounting an attachment on a vehicle body, comprising: a bracket for securement to the vehicle body; a connecting member for securement to the attachment; the bracket including two vertically spaced projections, each having means defining an upwardly opening notch; the connecting member including two respective pins, vertically spaced and extending transversally, for being cradled in the respective notches to connect the connecting member to the bracket; and a locking member, releasably actuable to prevent the connecting member from being raised sufficiently to permit the respective upper one of said pins from clearing the respective upper one of said notches; the locking member including means providing a contact surface on the underside of the respective upper one of said projections; a transversally extending lock pin mounted for movement transversally between a first operative position wherein said lock pin underlies and engages said contact surface, and a second inoperative portion wherein said lock pin clears said contact surface sufficiently to permit the connecting member to be raised enough to disconnect the connecting member from the bracket; and a hitch lever member secured crank fashion to the lock pin for actuating the lock pin between said first and second positions thereof.
Claim 2
Dependent Claim
203 words
A mounting apparatus for releasably mounting an attachment on a vehicle body, comprising: a bracket for securement to the vehicle body; a connecting member for securement to the attachment; the bracket including two vertically spaced projections, each having means defining an upwardly opening notch; the connecting member including two respective pins, vertically spaced and extending transversally, for being cradled in the respective notches to connect the connecting member to the bracket; and a locking member, releasably actuable to prevent the connecting member from being raised sufficiently to permit the respective upper one of said pins from clearing the respective upper one of said notches; the locking member including means providing a contact surface on the underside of the respective upper one of said projections; a transversally extending lock pin mounted for movement transversally between a first operative position wherein said lock pin underlies and engages said contact surface, and a second inoperative portion wherein said lock pin clears said contact surface sufficiently to permit the connecting member to be raised enough to disconnect the connecting member from the bracket; and a hitch lever member secured crank fashion to the lock pin for actuating the lock pin between said first and second positions thereof.
Claim 3
Dependent Claim
85 words
The mounting apparatus of claim 1, wherein: the hitch lever member is pivotally secured on the connecting member and is further provided with a resilient spring biased between the hitch member and the connecting member in a sense to tend to urge the lock pin to said first, operative position; and further including a stop plate movably mounted on the connecting member for selectively obstructing return of the hitch lever member, in order to maintain the lock pin in the second, inoperative position when desired.
Claim 4
Dependent Claim
174 words
The mounting apparatus of claim 1, wherein: the bracket further including a second set of vertically spaced projections, transversally spaced from the first-mentioned two projections, each of the projections of the second set having means defining an upwardly opening notch; the connecting member further including a second set of two respective pins, transversally spaced from the first-mentioned two pins, for being cradled in the notches of said second set; the locking member further including means providing a second contact surface on the underside of the respective upper one of the second set of projections; a second transversally extending lock pin mounted for movement transversally between a first, operative position wherein said second lock pin underlies and engages said second contact surface, and a second, inoperative position wherein said lock pin clears said second contact surface sufficiently to permit the connecting member to be disconnected from the bracket; said hitch lever member being secured crank fashion to said second lock pin for simultaneously actuating both said lock pins between said first and second positions thereof.
