Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
168 words
In combination with the arms of a high chair, a tray, and a swivel mounted on the underside of said tray and removably securable to one of said arms, the improvement comprising bracket means mounted on the underside of said tray in juxtaposition with said other arm; depending legs extending downward from said bracket so as to form a recess for said other arm; at least one aperture in the outer surface of said other arm; a plate rotatably mounted on said underside of said tray adjacent said depending legs; spring means for rotatably biasing said plate away from said underside of said tray and against said depending legs; a pin extending from said plate and being of a dimension to mate with said aperture; and a flange extending outwardly from said plate toward the outer edge of said tray, whereby movement of said flange in a direction toward the underside of said tray overcomes the bias of said spring means and removes said pin from said aperture.
Claim 2
Dependent Claim
168 words
In combination with the arms of a high chair, a tray, and a swivel mounted on the underside of said tray and removably securable to one of said arms, the improvement comprising bracket means mounted on the underside of said tray in juxtaposition with said other arm; depending legs extending downward from said bracket so as to form a recess for said other arm; at least one aperture in the outer surface of said other arm; a plate rotatably mounted on said underside of said tray adjacent said depending legs; spring means for rotatably biasing said plate away from said underside of said tray and against said depending legs; a pin extending from said plate and being of a dimension to mate with said aperture; and a flange extending outwardly from said plate toward the outer edge of said tray, whereby movement of said flange in a direction toward the underside of said tray overcomes the bias of said spring means and removes said pin from said aperture.
Claim 3
Dependent Claim
187 words
Apparatus for attaching a tray to the arm of a high chair comprising a swivel mounted on the underside of said tray; a channel integral with said swivel of a size to permit passage of one of said arms; means for releasably securing said one of said arms in said channel; bracket means mounted on the underside of said tray in juxtaposition with said other arm; depending legs extending downward from said bracket so as to form a recess for said other arm; at least one aperture in the outer surface of said other arm; a plate rotatably mounted on said underside of said tray adjacent said depending legs; spring means for rotatably biasing said plate away from said underside of said tray and against said depending legs; a pin extending from said plate and being of a dimension to mate with said aperture; and a flange extending outwardly from said plate toward the outer edge of said tray, whereby movement of said flange in a direction toward the underside of said tray overcomes the bias of said spring means and removes said pin from said aperture.
Claim 4
Dependent Claim
187 words
Apparatus for attaching a tray to the arm of a high chair comprising a swivel mounted on the underside of said tray; a channel integral with said swivel of a size to permit passage of one of said arms; means for releasably securing said one of said arms in said channel; bracket means mounted on the underside of said tray in juxtaposition with said other arm; depending legs extending downward from said bracket so as to form a recess for said other arm; at least one aperture in the outer surface of said other arm; a plate rotatably mounted on said underside of said tray adjacent said depending legs; spring means for rotatably biasing said plate away from said underside of said tray and against said depending legs; a pin extending from said plate and being of a dimension to mate with said aperture; and a flange extending outwardly from said plate toward the outer edge of said tray, whereby movement of said flange in a direction toward the underside of said tray overcomes the bias of said spring means and removes said pin from said aperture.
Claim 5
Dependent Claim
24 words
The apparatus of claim 2 wherein said flange extends from the outer end of said plate and away from the underside of said tray.
Claim 6
Dependent Claim
29 words
The apparatus of claim 2 wherein the axis of said pin is substantially perpendicular to the axis of said arm and substantially parallel to the plane of said tray.
