Abstract
Abstract A gutter protection device for preventing damage to an eaves-mounted gutter against which a ladder is leaned. A polyethylene foam block forms the body of the device. A semi-circular recess in one face of the body can be fitted on the lip of the gutter. A pair of pins which project from the body into the recess are then hooked behind the gutter lip to mount the device on the gutter. A bearing surface of the body has a pair of slots which receive the legs of the ladder. One slot closely receives the leg of the ladder to assist in preventing sideward sliding of the ladder. The other slot is oversized so that it can receive the legs of ladders having various sizes.

93 words
A device for application to a roof mounted gutter against which a ladder is to be leaned, said device comprising: a body having a length dimension sufficient to span the width of the ladder and a bearing surface for receiving the ladder; means for releasably mounting said body on the gutter with the length dimension of the body extending along the gutter and said bearing surface spaced away from the gutter; and means on said bearing surface for maintaining the ladder thereon and preventing the ladder from sliding sidewardly on said bearing surface.
Claim 2
Independent Claim
93 words
A device for application to a roof mounted gutter against which a ladder is to be leaned, said device comprising: a body having a length dimension sufficient to span the width of the ladder and a bearing surface for receiving the ladder; means for releasably mounting said body on the gutter with the length dimension of the body extending along the gutter and said bearing surface spaced away from the gutter; and means on said bearing surface for maintaining the ladder thereon and preventing the ladder from sliding sidewardly on said bearing surface.
Claim 3
Dependent Claim
73 words
A device as set forth in claim 1, wherein said mounting means includes: a recess in said body in a surface thereof opposite said bearing surface, said recess having a size and shape to be fitted on the gutter; and pin means projecting from said body into said recess and extending into the gutter when said recess is fitted on the gutter, said pin means acting to hold said body on the gutter.
Claim 4
Dependent Claim
24 words
A device as set forth in claim 2, wherein said pin means comprises a plurality of pins projecting from said body into the recess.
Claim 5
Dependent Claim
25 words
