Ladder accessory device

An accessory device for installation on a ladder having hollow rungs extending through a pair of spaced-apart rails comprising:

• an upper arm assembly having a first fixed arm adapted to fit within a hollow rung of a ladder and a second slidable arm within said first arm;
• a lower arm assembly having a first fixed arm adapted to fit within a lower hollow rung of the ladder and a second slidable arm within said first arm;
• a slot in each said fixed arm;
• a pin on each said slidable arm for engagement with said slot, each said pin slidable along each said slot upon a user exertion on each said slidable arm, said pin engagement with said respective slot precluding a relative movement between said respective fixed and slidable arms absent a user exertion on said slidable arm;
• a brace attached to said second slidable arms of each arm assembly;
• an aperture in said brace;
• a tray having a base;
• at least one flange depending from said base;
• an aperture in said flange;
• fastener means for defining a pivot axis extending through said brace and flange apertures upon alignment therebetween, said fastener means movable between a first position bearing against said at least one depending flange for precluding a movement of said depending flange about said pivot axis and a second position displaced from said at least one depending flange for allowing for said pivotal movement, whereby said fastener means and said slidable arms selectably position and maintain said tray at lateral and pivotal positions relative to the ladder.

A support device in combination with a ladder having hollow rungs extending through a pair of spaced-apart rails comprising:

• a first arm slidable along a first rung of the ladder;
• a second arm slidable along a second rung of the ladder;
• a slot extending along each of the first and second rungs of the ladder;
• a tray;
• means for pivotally mounting said tray to said slidable arms in movement therewith;
• a pin at an end of each slidable arm respectively slidable along each slot in the first and second ladder rungs, each said pin configured for a friction fit engagement within the respective slot whereby to position and maintain said slidable arms in extension from the rungs with said tray mounted thereto.

An accessory device for installation on a ladder having hollow rungs extending through a pair of spaced-apart rails comprising:

• at least one arm assembly having a first fixed arm adapted to fit within a hollow rung of a ladder and a second slidable arm within said first arm;
• a slot extending along one of said first or second arms of said at least one arm assembly;
• a pin on the other of said first or second arms of said at least one arm assembly for movement along said slot upon said slidable movement of said second arm relative to said first arm, said pin in engagement with said slot absent said slidable movement to maintain said second slidable arm at a selectable lateral position relative to said first fixed arm;
• a brace attached to said second slidable arm of said at least one arm assembly;
• a tray;
• means for mounting said tray to said brace whereby said fastener means and said slidable arms position and maintain said tray at selectable lateral and pivotal positions relative to the ladder.

An accessory device for installation on a ladder having hollow rungs extending through a pair of spaced-apart rails comprising:

• a first arm assembly having a configuration for insertion within a first hollow rung of a ladder, said first arm assembly comprising:
• a fixed arm adapted for insertion within the respective first hollow rung;
• a slidable arm within said fixed arm and slidable between a first position within said fixed arm and a second position extensible from said fixed arm;
• a second arm assembly having a configuration for insertion within a second hollow rung of the ladder, said second arm assembly comprising:
• a fixed arm adapted for insertion within the respective second hollow rung;
• a slidable arm within said fixed arm and slidable between a first position within said respective fixed arm and a second position extensible from said respective fixed arm;
• a slot in each said fixed arm;
• pin means on each said slidable arm for engagement with said slot, said pin means slidable along said slot upon a user exertion on said slidable arms, said pin means engagement with said slot precluding a relative movement between said fixed and slidable arms absent a user exertion on said slidable arms, said slidable arms presenting a support structure adapted for attachment of an accessory thereto whereby to position and maintain the accessory at selectable positions relative to the ladder.
