(NOT APPLICABLE)
The invention relates to a ladder system for recreational vehicles (RVs) and the like and, more particularly, to an easily attachable and detachable ladder system that provides for improved access to a vehicle roof.
Ladders mounted to the back or side of an RV such as a motor home or the like are known for the purpose of a user accessing the roof of the vehicle. Many RV ladders are fixed in place on a wall of the vehicle and are not meant to be removed. A permanently affixed ladder, however, is constantly subjected to environmental conditions and can be unsightly.
Multi-purpose telescoping ladders are known for easy storage by a user, but are generally not designed to be fixed to any structure.
Other ladders for use on vehicles are mountable to a wall and removable, but generally have a simple mounting member or hook connected to the side rails of the ladder. Still other vehicle-mounted ladders have a mounting point that is limited to the top end of the ladder.
The ladder system of the described embodiments is detachably mounted to the vehicle preferably at an intermediate rung of the ladder by a suitable wall-mounted bracket. In some embodiments, the ladder includes a telescoping ladder frame.
The wall-mounted bracket is generally meant to be mounted on the rear door of a vehicle such as a toy hauler, but could be mounted to any suitable wall of the vehicle, including front and side walls. The wall mount includes a metal or plastic engagement portion or is configured with openings used for securing the grips or hooks of a ladder securing bracket. In some embodiments, the engagement portion is held in place through apertures in the wall-mounted bracket and secured at the ends by end caps built into the bracket. The openings are formed integral with the wall mount. In some embodiments, the engagement portion is a bar formed as an integral part of the wall mount.
The ladder securing bracket may include a flat mounting portion that is secured to the underside of a ladder rung by fasteners. Two grips or hooks extend rearwardly from the flat mounting portion and are designed to engage the engagement portion or the openings of the wall mount. The engagement portion may be a bar, plate, flange, or other surface that is suitable to be grasped, hooked, or otherwise engaged by the grips. In some embodiments, the two grips or hooks are individually attached to the ladder by a mounting portion that is secured to each end of the ladder rung around the side rails.
In an exemplary embodiment, a ladder system is cooperable with a surface to which a wall mount is securable. 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 ladder system also includes a ladder with a plurality of rungs, and a securing bracket connected to one of the plurality of rungs. The securing bracket has a pair of grips that are sized to fit over the engagement portion of the wall mount in the first and second openings.
The wall mount may include a central bumper portion with a lateral channel therethrough with the engagement portion extending through the lateral channel, and first and second end caps connected to opposite ends of the engagement portion. In this context, the engagement portion may be a bar that is sized such that the first and second end caps are spaced from the central bumper portion, and the pair of grips may be 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. The length of the openings between the end caps and the central bumper may be similar to or slightly larger than the length of the grips to reduce lateral movement or sliding of the ladder when engaging the wall mount. The flat back section, the central bumper portion and the first and second end caps may be formed of injection molded plastic, rubber or metal. The bar may be cylindrical, and the grips may define at least part-circular sections that are sized to fit over the cylindrical bar. In some embodiments, the grips may be semi-circular.
The ladder may include a plurality of telescoping sections.
The securing bracket may include a flat mounting portion secured to an underside of the one of the plurality of rungs. The grips may be 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.
The one of the plurality of rungs to which the securing bracket is connected may be at an intermediate position of the ladder relative to others of the plurality of rungs.
The ladder may include side rails to which the plurality of rungs are connected between, and a width of the wall mount may be narrower than a distance between the side rails.
In another exemplary embodiment, a wall mount is securable to a surface and is cooperable with a securing bracket connected to one of a plurality of rungs on a ladder. The securing bracket includes a pair of grips. The wall mount includes an engagement portion, and a back section integral with the engagement portion and defining openings between the engagement portion and the back section. The wall mount is formed of a one-piece injection molded material, and the openings are spaced apart corresponding to a space between the grips. The wall mount may have a thickness defined by the space between the engagement portion and the back section. The engagement portion may extend across a width of the wall mount.
In yet another exemplary embodiment, a ladder system cooperable with a surface includes a ladder with a plurality of rungs, and a securing bracket connected to one of the plurality of rungs, where the securing bracket includes a pair of grips that are configured to engage a wall mount engagement portion. A wall mount may be securable to the surface and may include openings that are configured to receive the pair of grips. The openings may be sized substantially corresponding to a length of each of the pair of grips. The ladder may include side rails, and the rungs may extend between the side rails, where a width of the wall mount substantially corresponds to a distance between the side rails.
These and other aspects and advantages will be described in detail with reference to the accompanying drawings, in which:

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.
As most clearly shown in
As shown in
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.
