A ladder caddy which releasably secures to a vehicle to provide at least one enclosed space configured to contain a ladder for transportation.
Ladders comprise equipment commonly transported to and from construction or work sites. Conventional transportation of ladders typically involves placing the ladder(s) in the cargo space of the vehicle (such as the bed of a truck or the interior space of a station wagon or utility vehicle or the like), securing the ladder(s) to a roof top rack of the vehicle (such as tying the ladder(s) to the to the roof top rack or carrier with a rope, adjustable straps, bungee cords, or the like), or securing the ladder(s) to other types of conventional ladder racks (such as the conventional ladder rack connected to the vehicle shown by
Even though there is large commercial market for ladder racks and even though manufacturers have met the demand of that commercial market with a variety of convention ladder racks, there are still a number of problems unresolved by conventional ladder racks or conventional carriers.
A significant problem with conventional carriers which releasably secures to a vehicle can be that the interior space of the conventional carrier is not configured to contain a ladder. Surprisingly, it appears that it has been entirely overlooked to configure a carrier releasably secured to a vehicle to contain a ladder within. However, even if the interior volume of a conventional carrier was increased sufficiently to locate a ladder inside, this approach would not address the various problems associated with transporting ladders as further described below.
Importantly, the well known conventional approach of transporting ladders secured to a framework of connected uprights and cross members connected to the vehicle, often referred to as a “ladder rack”, teaches away from containing the ladder(s) in an enclosed space or configuring an enclosed space to contain a ladder for transportation and to the extent that the disclosure or use of the conventional ladder rack teaches away from the instant ladder caddy invention it has made the solution afforded by the ladder caddy invention less obvious.
As to conventional ladder racks, a significant problem can be that that the framework of the conventional ladder rack does not provide any securement means. The lack of securement means necessitates the use of ropes, cords, adjustable straps, bungee cords, or the like, to secure the ladder(s) to the conventional ladder rack. However, even when secured to the conventional ladder rack as above-described, the ladder(s) may still shift on the conventional ladder rack or come loose during transit. The use of ropes, cords, adjustable straps, bungee cords, or the like also necessitates expenditure of a significant amount of time and effort to make certain that the ladders are properly secured.
Another significant problem with conventional ladder racks can that the conventional rack has a fixed configuration that may not accommodate the number or various configurations of ladders which are typically transported to and from the construction or work site. One aspect of this problem can be that ladder racks are not configured to stack ladders upon each one another for transportation. None-the-less, when several ladders must be transported using a conventional ladder rack, it may be that only way to accomplish the effort is by stacking of ladders upon each other. This only serves to exacerbate the difficulty of using ropes, cords, adjustable straps, bungee cords, or the like to properly secure the ladders to the ladder rack. Also, certain ladder configurations may be too short to allow securement of the laddder ends to the uprights or cross members of the conventional ladder carrier which further encourages short ladders to be stacked upon long ladders to allow securement.
Another significant problem with conventional ladder racks can be that the ladder being transported is exposed to the environment during transport. The transported ladder(s) can as a result get wet or collect material on the surface such as dirt, mud, grit, sand, bug carcasses, or the like. The exposure to moisture and the material(s) collected on the ladder surface may damage the ladder, result in increased wear of the ladder, or necessitate removal of the material further contributing to increased efforts or costs of transporting ladders in the conventional manner.
Another significant problem with conventional ladder racks can be the lack of security means to prevent or deter theft of the ladders. Conventional methods of securement such as ropes, straps, bungee cords, or the may not include security means. The ropes, straps, or bungee cords are simply removed and the ladder(s) can be immediately removed from the conventional ladder rack.
Yet another significant problem with conventional ladder racks can be the lack of compartmentalization. Conventional ladder racks or carriers typically provide cross members to which ladders and other material, such as lengths of pipe, sheet material, board material, or the like, are secured. The can result in the engagement of the various surfaces of the ladder(s) or other material(s) resulting in abrasion or impact damage as the ladder(s) or other materials shift during transit. Alternately, in those instances in which the uprights or cross members of the conventional ladder rack provide segregation means to secure, for example, the ladder(s) from the pipe(s), the segregation means may be a fixed configuration or a configuration which does not allow adjustment to a variety of ladder configurations.
Still another significant problem with conventional ladder racks along with the ladders or other materials secured to the conventional ladder rack can be the lack of aerodynamic configuration. The ladder(s) or other material(s) generate resistance to the flow of air across the corresponding surfaces which can create turbulence sufficient to effect travel of the vehicle, or generate travel, flexure, or shift in the ladder(s) or other material(s) which can result in damage to the vehicle, the ladders, or the materials during transit.
Accordingly, a broad object of the invention can be to provide a ladder caddy which releasably secures to a vehicle which provides at least one enclosed space configured to contain a ladder.
A second broad object of the invention can be to provide a ladder caddy which has at least one enclosed space configured to secure a ladder within without the use of ropes, cords, adjustable straps, bungee cords, or the like.
A third broad object of the invention can be to provide a ladder caddy which provides a plurality of discrete enclosed spaces each configured to contain a ladder. The plurality of enclosed spaces can be joined to in a manner which provides a wall, partition, divider, or the like, between each of the plurality of enclosed spaces which act to prevent the surfaces of the plurality of ladders contained within from engaging to avoid or minimize abrasion or impact damage.
A fourth broad object of the invention can be to provide a ladder caddy which allows a plurality of ladders to be stacked one above the other and secured without the use of ropes, cords, adjustable straps, bungee cords, or the like.
A fifth broad object of the invention can be to provide a ladder caddy having a plurality of enclosed spaces each differently configured to contain a variety of ladder configurations. One aspect of this object of the invention can be to provide interchangeable enclosed spaces which allows the user to select the configuration of ladder caddy most useful to a particular application.
A sixth broad object of the invention can be to provide a ladder caddy having at least one enclosed space configured to contain a ladder which further provides a lockable closure.
A seventh broad object of the invention can be to configure the exterior surface of the ladder caddy to reduce resistance to airflow and to improve handling characteristics of the vehicle.
Naturally, further objects of the invention are disclosed throughout other areas of the specification, drawings, photographs, and claims.
