DETAILED DESCRIPTION

[0031] With reference to FIG. 1, a ladder system 10 is cooperable with a surface S such as a back door or side wall of an RV. The ladder system 10 includes a wall mount 12 securable to the surface S. With reference to FIG. 2, the wall mount 12 includes a central bumper portion 14 with a lateral channel 16 therethrough. An engagement portion 18, shown as a bar in this embodiment, extends through the lateral channel 16. First and second end caps 20 are connected to opposite ends of the bar 18. The end caps 20 include channels 22 therein that receive distal ends of the bar 18. As shown, the bar 18 is sized such that the first and second end caps 20 are spaced from the central bumper portion 14.

[0032] FIG. 3 is an exploded view of the wall mount 12. The wall mount 12 is also provided with a flat back section 24 that is securable to the surface S. The flat back section 24 can be secured to the surface S by any suitable method such as fasteners or a strong adhesive or the like. In some embodiments, the central bumper portion 14 and the first and second end caps 20 are integral with the flat back section 24. Alternatively, the first and second end caps 20 may be attached to end cap tabs 26 and the flat back section 24 via welding or the like. The flat back section 24, the central bumper portion 14 and the first and second end caps 20 may be formed of injection molded plastic, rubber or metal. The wall mount 12 defines openings 19 (FIG. 2) between the engagement portion 18 and the flat back section 24.

[0033] With reference to FIG. 4, the ladder system 10 also includes a ladder 28 with side rails 30 and a plurality of rungs 32 secured between the side rails 30. In some embodiments, the side rails 30 are constructed of a plurality of telescoping tubes or the like. Telescoping ladders of this type are known, and further details thereof will not be described.

[0034] With reference to FIGS. 4 and 5, a securing bracket 34 is connected to one of the rungs 32. The securing bracket 34 includes a pair of grips 36 that are sized to fit over the engagement portion 18 of the wall mount 12, through the openings 19 (FIG. 2). The grips 36 are spaced apart such that the grips 36 respectively engage the engagement portion 18 in the spaces between the first and second end caps 20 and the central bumper portion 14, respectively. See FIG. 6. In some embodiments, the length or distance 35 (FIG. 2) between the end caps 20 and central bumper 14 may substantially correspond to (i.e., may be similar to or slightly larger than) the length 37 (FIG. 4) of the grips 36 to reduce lateral movement or sliding of the grips when engaging the wall mount.

[0035] In some embodiments, the engagement portion 18 is cylindrical, and the grips 36 define at least part-circular sections or semi-circular sections that are sized to fit over the cylindrical engagement portion or bar 18. The part- or semi-circular grips 36 are configured to interact with the cylindrical engagement portion 18 of the wall mount 12 and work with gravity to secure the ladder 28 in place. The part- or semi-circular shape also allows for pivoting to adjust the angle of the ladder 28 relative to the surface S depending on the terrain and ground-engagement of the bottom of the ladder 28.

[0036] As most clearly shown in FIG. 5, the securing bracket 34 includes a flat mounting portion 38 that is secured to an underside of the ladder rung 32 via suitable connectors or the like. The grips 36 are preferably monolithic with the flat mounting portion 38 and extend from the rung 32 rearward toward the surface S to which the wall mount 12 is securable. As shown in FIG. 7, the rung 32 to which the securing bracket 34 is connected may be at an intermediate position of the ladder 28 relative to others of the plurality of rungs 32. In this way, portions of the ladder 28 extend above the point at which the ladder engages the wall mount 12. Moreover, the placement of the mounting system at an intermediate portion of the ladder makes installation and removal easier for the user.

[0037] As shown in FIG. 6, a width 39 of the wall mount 12 may be narrower than a distance between the side rails 30. As such, the securing bracket 34 and the wall mount 12 are discrete and do not get in the way of the user as the user is climbing the ladder. In some embodiments, the width 39 of the wall mount 12 may substantially correspond to (i.e., similar to or slightly narrower than) the distance between the side rails 30 to fit within the space between the side rails to reduce lateral movement or sliding of the ladder 28 when installed onto the wall mount 12.

[0038] The construction of the wall mount 12 accommodates for the size of the grips 36 of the ladder securing bracket 34 and also creates a wall between the grips 36 and the surface S to prevent damage or scratches to the surface S. The end caps 20 and the central bumper portion 14 of the wall mount 12 create guides for receiving the grips 36 and may abut the inner surfaces of the ladder side rails 30 for added securement and safety of the ladder while in use.

[0039] FIGS. 8-12 show an alternative embodiment of the ladder system. In this embodiment, the ladder system 110 similarly includes a wall mount 112, a ladder 128, and a securing bracket 134 connected to the ladder 128 and engageable with the wall mount 112.

[0040] With reference to FIGS. 9 and 10, the wall mount 112 is in the form of a one-piece injection molded nylon or similar material. The wall mount 112 includes a plurality of apertures 113 for securing the wall mount 112 to the surface S with suitable fasteners. The wall mount 112 includes a front section or engagement portion 118 integrated with a back section 124 and including openings 119 between the engagement portion 118 and the back section 124. The wall mount 112 has a thickness defined by the space between the engagement portion 118 and the back section 124. The engagement portion 118 extends across a width of the wall mount 112 as shown in FIG. 9.

[0041] As shown in FIG. 10, the back section 124 includes apertures 121 (e.g., square apertures in FIG. 10) that delimit the openings 119 in the wall mount 112. The openings 119 are spaced apart from each other in a manner similar to the spaces between the first and second end caps 20 and the central bumper portion 14 in the first embodiment.

[0042] The ladder 128 with side rails 130 and a plurality of rungs 132 secured between the side rails 130 is similar to the ladder 28 from the first embodiment. The side rails 130 may be constructed of a plurality of telescoping tubes or the like.

[0043] With reference to FIG. 11, the securing bracket 134 is connectable to one of the rungs 132 of the ladder 128. The securing bracket 134 includes a pair of grips or hooks 136 that are sized to fit in the openings 119 in the wall mount 112. That is, the grips or hooks 136 are spaced apart such that the grips or hooks 136 respectively engage the front section or engagement portion 118 of the wall mount 112 via the openings 119. In some embodiments, the length of the openings 119 may be similar to or slightly larger than the length of the grips 136 to reduce lateral movement or sliding of the grips when engaging the wall mount 112.

[0044] The securing bracket 134 includes a flat mounting portion 138 that is secured to an underside of the ladder rung 132 via suitable connectors or the like. The grips or hooks 136 are preferably monolithic with the flat mounting portion 138 and extend from the rung 132 rearward toward the surface S to which the wall mount 112 is securable.

[0045] FIG. 12 shows the ladder 128 and securing bracket 134 secured on the wall mount 112. The grips or hooks 136 are configured to allow for some pivoting relative to the wall mount. The grips or hooks 136 can be readily engaged in the openings 119 to facilitate securing the ladder 128 to the wall mount 112. Additionally, openings in the wall mount 112 and the length of the grips or hooks 136 serve to ensure that the grips or hooks 136 are prevented from slipping out of the wall mount openings 119 while the ladder is in use. Moreover, the openings in the wall mount 112 prevent water-retention.

[0046] FIG. 13 shows an alternative ladder securing bracket 234 for use in a ladder system that is similar to the embodiment of FIG. 8. The securing bracket 234 includes two hollow mounting portions 238 that are connectable to each end of one of the rungs 232 of the ladder 228. The mounting portions 238 have a vertical opening 239 that is shaped to correspond to the shape of the ladder side rails 230. The mounting portions 238 also include a side opening 241 that corresponds to the shape of the ladder rung 232. The vertical openings 239 and the side openings 241 are complementary to the ladder 228 to mitigate movement or shifting between the mounting portions 238 and the ladder 228. The mounting portions 238 of the securing bracket 234 may be injection molded to be integral with the ladder 228 or may include a slit or hinge (not shown) to grasp the ladder rung or clip into place.

[0047] The securing bracket 234 includes a pair of grips or hooks 236 that are similar to the securing bracket 134 of the second embodiment. The grips or hooks 236 are similarly sized to fit into openings in a wall mount similar to wall mount 112 of the second embodiment. The wall mount that engages securing bracket 234 may be wider or may have wider openings to accommodate the distance between mounting portions 238.

[0048] While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not to be limited to the disclosed embodiments, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
