Ladder support device for roof

[0002] 1. Field of the Invention

[0003] The present invention relates to ladder support devices and more particularly pertains to a new ladder support device for a roof for holding a ladder on a roof.

[0004] 2. Description of the Prior Art

[0005] The use of ladder support devices is known in the prior art. More specifically, ladder support devices heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.

[0006] Known prior art includes U.S. Pat. No. 4,678,061; U.S. Pat. No. 4,179,011; U.S. Pat. No. 4,787,478; U.S. Pat. No. 4,880,200; U.S. Pat. No. 1,007,347; and U.S. Des. Pat. No. 332,667.

[0007] While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new ladder support device for a roof. The inventive device includes a first plate and a second plate. The first plate has a bottom edge, a top edge and a pair of side edges. The second plate has a bottom edge, a top edge and a pair of side edges. The top edges of the first and second plates are attached to each other along their lengths such that the plates are in an angular relationship with respect to each other. The plates have a top surface and a bottom surface. A bracket is coupled to the bottom edge of the first plate for removably engaging a top rung of the ladder. A block member is attached to the bottom surface of the first plate. The block member is positioned adjacent to and extends along the width of the second plate. The plates are placed on opposite sides of a roof to hold the ladder on the roof.

[0008] In these respects, the ladder support device for a roof according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of holding a ladder on a roof.

[0009] In view of the foregoing disadvantages inherent in the known types of ladder support devices now present in the prior art, the present invention provides a new ladder support device for a roof construction wherein the same can be utilized for holding a ladder on a roof.

[0010] The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new ladder support device for a roof apparatus and method which has many of the advantages of the ladder support devices mentioned heretofore and many novel features that result in a new ladder support device for a roof which is not anticipated, rendered obvious. suggested, or even implied by any of the prior art ladder support devices, either alone or in any combination thereof.

[0011] To attain this, the present invention generally comprises a first plate and a second plate. The first plate has a bottom edge, a top edge and a pair of side edges. The second plate has a bottom edge, a top edge and a pair of side edges. The top edges of the first and second plates are attached to each other along their lengths such that the plates are in an angular relationship with respect to each other. The plates have a top surface and a bottom surface. A bracket is coupled to the bottom edge of the first plate for removably engaging a top rung of the ladder. A block member is attached to the bottom surface of the first plate. The block member is positioned adjacent to and extends along the width of the second plate. The plates are placed on opposite sides of a roof to hold the ladder on the roof.

[0012] There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.

[0030] With reference now to the drawings, and in particular to FIGS. 1 through 3 thereof, a new ladder support device for a roof embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

[0031] As best illustrated in FIGS. 1 through 3, the ladder support device 10 generally comprises a first plate 12 and a second plate 14. The first plate 12 has a bottom edge 16, a top edge 18 and a pair of side edges 20. The second plate 14 has a bottom edge 22, a top edge 24 and a pair of side edges 26. The top edges 18, 24 of the first 12 and second 14 plates are attached to each other along their lengths such that the plates 12, 14 are in an angular relationship preferably between 90 degrees and 135 degrees with respect to each other. The plates 12, 14 have a top surface 28 and a bottom surface 30. The first plate 12 has a length extending between the top 18 and bottom 16 edges generally between 3 feet and 5 feet. The second plate 14 has a length extending between the top 24 and bottom 22 edges generally between 2 feet and 4 feet. The first 12 and second 14 plates each have a width between the side edges 20, 26 generally between 12 inches and 18 inches. Each of the side edges 20 of the first plate 12 has an arcuate groove 32 therein. The plates 12, 14 are rigid and preferably comprise a plastic material.

[0032] A bracket 34 is coupled to the bottom edge 16 of the first plate 12. The bracket 34 has an arm portion 36 and a hand portion 38 coupled together at a perpendicular orientation to each other. The arm portion 36 is coupled to and extends along the bottom edge 16 of the first plate 12 and is orientated perpendicular to the first plate 12 such that the hand portion 38 is spaced from and positioned below the first plate. The bracket 34 is positioned around a first rung 70 of a ladder 72 such that the first rung 70 is positioned between the first plate 12 and the hand portion 38. The arm portion 36 has a height generally between 3 inches and 4 inches.

[0033] A block member 40 is attached to the bottom surface 30 of the first plate 12. The block member 40 is positioned adjacent to and extends along the width of the second plate 14. The block member 40 extends away from the first plate 12 a distance substantially equal to a height of the arm portion 36. The block member 40 comprises a resiliently flexible material.

[0034] An elastomeric coating 42 is attached to and generally coats the bottom surface 30 of the second plate 14 and an inner surface of the bracket 36 directed toward bottom surface 30 of the first plate 12.

[0035] A nodule 44 is coupled to the top surface 28 of the second plate 14 and is positioned generally adjacent to the bottom edge 22 of the second plate 14. The nodule 44 has a forward side positioned adjacent to the bottom edge 22 of the second plate. The forward side has a threaded bore 46 therein. A pole 48 is elongated and has a first end 50 and a second end 52. An outer surface 54 of the pole adjacent to the first end 50 of the pole 48 is threaded. The first end 50 of the pole 48 may be extended into and threadably engaged to the threaded bore 46.

[0036] In use, the pole 48 is inserted into the nodule 44 and the pole 48 used to lift the device on the roof 74 of a dwelling. The bracket 34 is positioned around the top rung 70 of a ladder 72 with the second plate 14 abutted against the roof 74 as shown in FIG. 1. The block member 40 spaces the first plate 12 away from the roof 74 and the elastomeric coating 42 protects the roof 74 and helps to make the device non-slip.
