Abstract
Abstract A ladder caddy for attachment to a side rail of a ladder to provide an attachment support for tools, paint can etc., the caddy having a J-shaped frame to straddle a side rail with a dual bight in one embodiment to provide built in capability to fit two ranges of width of ladder side rails and rung catch means for engagement with a surface of one of the ladder rungs. In one embodiment the rung catch means is a rung insert of star-shaped section having trimmable lobes, to permit selective fitting of the support plug to the interior surface of the ladder rung in the use of ladders where the interior of the rungs are accessible; a further embodiment has rung catch means comprising an internal hook member for insertion within a ladder rung, and in another embodiment the rung catch means comprises a hook to engage externally over the ladder rung, being useable with most types of ladder.

Claim 1
Independent Claim
140 words
In a ladder caddy, for use with house ladders of the type having opposed side rails and a plurality of rungs extending therebetween, said caddy having a frame portion comprising a rigid J-frame having a long limb and a short limb, said limbs forming a bight therebetween to straddle over a said ladder side rail when in use with an erected ladder to locate said side rail in partially entered relation between said limbs, each said limb having a bore therethrough, the bores being in mutually aligned relation to receive an appliance support spindle in substantially horizontally extending relation therethrough in load transfer relation with said rigid J-frame, and rung catch means attached to said long limb and extending therefrom to engage a said rung, to pivotally secure said J-frame in stable mounted and load supporting relation upon said ladder.
Claim 2
Dependent Claim
140 words
In a ladder caddy, for use with house ladders of the type having opposed side rails and a plurality of rungs extending therebetween, said caddy having a frame portion comprising a rigid J-frame having a long limb and a short limb, said limbs forming a bight therebetween to straddle over a said ladder side rail when in use with an erected ladder to locate said side rail in partially entered relation between said limbs, each said limb having a bore therethrough, the bores being in mutually aligned relation to receive an appliance support spindle in substantially horizontally extending relation therethrough in load transfer relation with said rigid J-frame, and rung catch means attached to said long limb and extending therefrom to engage a said rung, to pivotally secure said J-frame in stable mounted and load supporting relation upon said ladder.
Claim 3
Dependent Claim
48 words
The ladder caddy as claimed in claim 1 wherein said rung catch means comprises spindle means extending laterally from adjacent the end of said long limb opposite to said bight, in use as follows to extend within the interior of a said rung in load transfer relation therewith.
Claim 4
Dependent Claim
63 words
The ladder caddy as claimed in claim 2 said J-frame having a first mouth portion of predetermined width, in use as follows to receive a first size of ladder side rail in engaged relation therein, and a second throat portion adjacent said mouth portion, in use as follows to receive a ladder side rail of a second size less than said first size.
Claim 5
Dependent Claim
32 words
The ladder caddy as claimed in claim 2 said spindle means having an outer plug portion, in use as follows to slideably penetrate a said rung interior in withdrawable fitting relation therewith.
Claim 6
Dependent Claim
