Abstract

A ladder system is cooperable with a surface such as a recreational vehicle rear wall or the like and includes a wall mount securable to the surface, a ladder with a plurality of rungs, a securing bracket connected to one of the plurality of rungs. The wall mount includes a flat back section engageable with the surface, an engagement portion connected to the flat back section, and first and second openings between the engagement portion and the flat back section, where the first and second openings are spaced from each other. The securing bracket of the ladder system includes a pair of grips that are sized to fit over the engagement portion of the wall mount in the first and second openings.

Claims (34)

1 . A ladder system cooperable with a surface, the ladder system comprising:

a wall mount securable to the surface, the wall mount including:

a flat back section engageable with the surface,

an engagement portion connected to the flat back section, and

first and second openings between the engagement portion and the flat back section, wherein the first and second openings are spaced from each other and include a vertical axis through the wall mount between the flat back section and the engagement portion, wherein each of the first and second openings comprises a defined closed perimeter in a top surface of the wall mount;

a ladder including a plurality of rungs; and

a securing bracket connected to one of the plurality of rungs, the securing bracket including a pair of grips that are sized to fit over the engagement portion of the wall mount and into the defined closed perimeter of the first and second openings.

2 . A ladder system according to claim 1 , wherein the engagement portion comprises a bar, wherein the wall mount comprises a central bumper portion with a lateral channel therethrough with the bar extending through the lateral channel, and first and second end caps connected to opposite ends of the bar, wherein the bar is sized such that the first and second end caps are spaced from the central bumper portion, the pair of grips being spaced apart such that the grips respectively engage the bar between the first end cap and the central bumper portion and between the second end cap and the central bumper portion.

3 . A ladder system according to claim 2 , wherein the flat back section, the central bumper portion and the first and second end caps are formed of injection molded plastic, rubber or metal.

4 . A ladder system according to claim 2 , wherein the bar is cylindrical, and wherein the grips define at least part-circular sections that are sized to fit over the cylindrical bar.

5 . A ladder system according to claim 4 , wherein the grips are semi-circular.

6 . A ladder system according to claim 1 , wherein the ladder comprises a plurality of telescoping sections.

7 . A ladder system according to claim 1 , wherein the securing bracket comprises a flat mounting portion secured to an underside of the one of the plurality of rungs.

8 . A ladder system according to claim 7 , wherein the grips are monolithic with the flat mounting portion and extend from the one of the plurality of rungs rearward toward the surface to which the wall mount is securable.

9 . A ladder system according to claim 1 , wherein the one of the plurality of rungs to which the securing bracket is connected is at an intermediate position of the ladder relative to others of the plurality of rungs.

10 . A ladder system according to claim 1 , wherein the ladder includes side rails to which the plurality of rungs are connected between, and wherein a width of the wall mount is narrower than a distance between the side rails.

11 . A wall mount securable to a surface and cooperable with a securing bracket connected to one of a plurality of rungs on a ladder, the securing bracket including a pair of grips, the wall mount comprising:

an engagement portion; and

a back section integral with the engagement portion and defining openings between the engagement portion and the back section,

wherein the wall mount is formed of a one-piece injection molded material, wherein the openings are spaced apart corresponding to a space between the grips, and wherein the openings include a vertical axis through the wall mount between the back section and the engagement portion, wherein each of the first and second openings comprises a defined closed perimeter in a top surface of the wall mount.

12 . A wall mount according to claim 11 , wherein the wall mount has a thickness defined by the space between the engagement portion and the back section.

13 . A wall mount according to claim 12 , wherein the engagement portion extends across a width of the wall mount.

14 . A ladder system cooperable with a surface, the ladder system comprising:

a wall mount securable to the surface, the wall mount including a flat back section engageable with the surface, an engagement portion connected to the flat back section, and first and second openings between the engagement portion and the flat back section, wherein the first and second openings are spaced from each other;

a ladder including a plurality of rungs extending between a pair of side rails; and

a securing bracket connected to one of the plurality of rungs, the securing bracket including a pair of grips that are sized to fit over the engagement portion in the first and second openings,

wherein the securing bracket comprises a flat mounting portion secured to an underside of the one of the plurality of rungs.

15 . A ladder system according to claim 14 , wherein the grips are monolithic with the flat mounting portion and extend from the one of the plurality of rungs rearward toward the surface.

16 . A ladder system according to claim 14 , wherein the one of the plurality of rungs to which the securing bracket is connected is at an intermediate position of the ladder relative to others of the plurality of rungs.

17 . A ladder system according to claim 14 , wherein the engagement portion comprises a bar, the wall mount including a central bumper portion with a lateral channel therethrough, the bar extending through the lateral channel, and first and second end caps connected to opposite ends of the bar, wherein the bar is sized such that the first and second end caps are spaced from the central bumper portion, and wherein the grips are spaced apart such that the grips respectively engage the bar between the first end cap and the central bumper portion and between the second end cap and the central bumper portion.

18 . A ladder system according to claim 14 , wherein the wall mount is formed of a one-piece injection molded material and includes a back section and the openings between the wall mount engagement portion and the back section.

19 . A ladder system according to claim 14 , wherein the wall mount includes the openings that are configured to receive the pair of grips.

20 . A ladder system according to claim 19 , wherein the openings are sized substantially corresponding to a length of each of the pair of grips.

21 . A ladder system according to claim 19 , wherein a width of the wall mount substantially corresponds to a distance between the side rails.
