High chair tray attachment

Claim 2

Detachable tray apparatus for a high chair having a pair of spaced arm rails comprising, means providing a substantially planar surface spanning the distance between the pair of spaced arm rails and a pair of spaced attachment means affixed to said means providing a substantially planar surface and selectively engaging the arm rails, said attachment means having pivotally mounted gripper means movable from an open position into engagement with a portion of the periphery of an arm rail for maintaining the tray in a locked position, said gripper means having projecting ends for encasing a plurality of sides of an arm rail and having an intermediate leg joining said projecting ends which selectively bends to facilitate bringing said projecting ends into and out of locking engagement with the arm rails.

Claim 3

Apparatus according to claim 1, wherein said projecting ends and said intermediate leg overlie substantially three sides of an arm rail.

Claim 4

Apparatus according to claim 1, wherein said attachment means includes hinge means pivotally mounting said gripper means.

Claim 5

Apparatus according to claim 1, wherein said attachment means are positioned laterally outwardly of the arm rails when the tray is in said locked position.

Claim 6

Apparatus according to claim 4, including stop means positioned laterally of at least one of the arm rails for resisting forces applied laterally of the tray.

Claim 7

Apparatus according to claim 5, wherein said stop means include a pair of stop bars attached to the underside of said means providing a substantially planar surface, one of said stop bars being positioned laterally inwardly of each of the arm rails when the tray is in said locked position.

Claim 8

Apparatus according to claim 5, wherein said stop means include a pair of stop bars attached to the underside of said means providing a substantially planar surface, one of said stop bars being positioned laterally outwardly of each of the arm rails when the tray is in said locked position.

Claim 9

Apparatus according to claim 7, wherein said stop bars extend in either direction from and are substantially longitudinally aligned with said attachment means when the tray is in said locked position.

Claim 10

Apparatus according to claim 1, wherein said gripper means has release means to facilitate detachment of said gripper means from locking engagement with the arm rails for removal of the tray from a high chair.

Claim 11

Apparatus according to claim 9, wherein said release means is an extending arm which is depressed to flex said gripper means for detachment from the arm rails.

Claim 12

Apparatus according to claim 10, wherein said gripper means have an intermediate leg joining projecting ends and said arm of said release means is attached proximate one of said projecting ends for flexing said intermediate leg to permit detachment of said gripper means from the arm rails.

Claim 13

Apparatus according to claim 10, wherein said gripper means is pivotally mounted such that the combined pivoting and flexing of said gripper means effects attachment and detachment of the tray to the arm rails.

Claim 14

Apparatus according to claim 1, wherein one of said projecting ends engages said means providing a substantially planar surface when the tray is in the locked position.

Claim 15

Detachable tray apparatus for a high chair having a pair of spaced arm rails comprising, means providing a substantially planar surface spanning the distance between the pair of spaced ar rails and a pair of spaced attachment means affixed to said means providing a substantially planar surface and selectively engaging the arm rails, each of said attachment means having hinge means pivotally mounting gripper means movable from an open position into engagement with a portion of the periphery of an arm rail for effecting alignment and locking engagement with the pair of spaced arm rails, said attachment means having spring means for biasing said gripper means toward said open position.

Claim 16

Detachable tray apparatus for a high chair having a pair of spaced arm rails comprising, means providing a substantially planar surface spanning the distance between the pair of spaced ar rails and a pair of spaced attachment means affixed to said means providing a substantially planar surface and selectively engaging the arm rails, each of said attachment means having hinge means pivotally mounting gripper means movable from an open position into engagement with a portion of the periphery of an arm rail for effecting alignment and locking engagement with the pair of spaced arm rails, said attachment means having spring means for biasing said gripper means toward said open position.

Claim 17

Detachable tray apparatus for a high chair having a pair of spaced arm rails comprising, means providing a substantially planar surface spanning the distance between the pair of spaced arm rails and a pair of spaced attachment means affixed to said means providing a substantially planar surface and selectively engaging the arm rails, each of said attachment means having hinge means pivotally mounting gripper means movable from an open position into engagement with a portion of the periphery of an arm rail for maintaining the tray in a locked position, said hinge means including fixed knuckle means having a bore mounted on the underside of said means providing a substantially planar surface, movable knuckle means having a bore on said gripper means, and pin means interconnecting said bores of said fixed knuckle means and said movable knuckle means, one of said bores of said knuckle means being elongate for providing an extent of lateral movement of said gripper means to accommodate arm rails having differing dimensions and arm rails having different spacing therebetween.

Claim 18

Detachable tray apparatus for a high chair having a pair of spaced arm rails comprising, means providing a substantially planar surface spanning the distance between the pair of spaced arm rails and a pair of spaced attachment means affixed to said means providing a substantially planar surface and selectively engaging the arm rails, each of said attachment means having hinge means pivotally mounting gripper means movable from an open position into engagement with a portion of the periphery of an arm rail for maintaining the tray in a locked position, said hinge means including fixed knuckle means having a bore mounted on the underside of said means providing a substantially planar surface, movable knuckle means having a bore on said gripper means, and pin means interconnecting said bores of said fixed knuckle means and said movable knuckle means, one of said bores of said knuckle means being elongate for providing an extent of lateral movement of said gripper means to accommodate arm rails having differing dimensions and arm rails having different spacing therebetween.

Claim 19

Apparatus according to claim 15, wherein spring means biases said gripper means laterally toward engagement with the arm rails.
