The ladder storage rack includes at least one strut having first and second opposing ends, a top side, a bottom side and a means for substantially horizontally mounting the strut to said surface, a sliding mount movably connected to the bottom of the at least one strut that slideably moves horizontally between the first and second ends of the strut, a fixed mount attached to the at least one strut between the sliding mount and one of the first and second ends and a means connected to the sliding mount for urging the sliding mount towards the fixed mount.

Description

The present invention is a sliding ladder rack for providing an adjustable sliding mount that connects to universally available hanger strut (some brands are commonly referred to as “Unistrut” or “B-Line”) to easily slide and hold a ladder inside a vehicle without having to enter the vehicle or use additional straps or clamping devices to maintain a secure mount. The ladder rack can be used on the interior ceiling of a vehicle which is the area least occupied on most vehicles, but may also be mounted in many other environments and locations. Placing the ladder inside the vehicle and near the roof of the vehicle keeps the ladder clean, and avoids damage by not being in contact with other items being stored in the same cargo space.
One problem with existing devices that store ladders inside of or on vehicles is that mounting and removing the ladder can be difficult in confined spaces, such as in the back of a vehicle, where reaching hooks or other hanging devices may be impractical. Another problem with existing devices are if a vehicle's compartment is crowded with materials, usage of such products is cumbersome and they don't provide both horizontal and vertical mounting options to make full use of the cargo space. Another problem with existing devices is that many ladder mounts are for mounting ladders outside of the vehicle thereby exposing them to the weather and increasing the likelihood of theft. Also, many existing devices require additional clamping or strapping to hold a ladder firmly in place.
The present invention overcomes the problems of existing devices, the sliding ladder rack substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus developed for the purpose of providing an adjustable sliding mount that connects to universally available hanger strut to easily slide and hold a ladder inside a vehicle without having to enter the vehicle or use additional means to hold the ladder securing in position.
In one embodiment, the present invention generally comprises a sliding front mount 20, adjustable receiving pin 22, a fixed mount 30, adjustable catch 32, front stop 40, rear stop 46. An elastic shock cord 60 is also provided as shown in FIGS. 4-6. The sliding front mount 20 is designed to fit inside between the rails on 1⅝″ hanger strut and has an “H” section 24 that, when inserted into a strut the “H” portion 24 cannot fall out of or rise into the strut 10 but remains free to slide linearly along the strut 10 rails. The opposite end of mount 20 has a slot 25 for a bolt or other connector that connects the adjustable receiving pin 22 having a grooved mating surface 28 to prevent slippage. There is also an attachment point for a shock cord 60 toward the top section of the structure. The receiving pin 22 has a grooved peg-like section 26 that is to be inserted into the ladder. The grooves aid in holding the ladder to the receiving pin 22 during removal and insertion. This receiving pin 22 has a slot or hole for a bolt or other connector that connects to the sliding mount 20 and a grooved mating surface to prevent slippage.
The fixed mount 30 is designed to be attached firmly to the 1⅝″ strut 10 by means of bolting through 2 holes 34 in the top of the mount 30. The lower portion has a grooved mating surface 36 to prevent slippage with the adjustable catch 32. It also has a slot 38 along the center to accommodate a bolt or other connector that tightens the adjustable catch 32 to the mount 30. The working portion 33 has a “V” shape that physically holds the rung or rung support to the ladder and includes notches to accommodate the ladder rungs when the ladder is stored with the sides vertical. This catch is wide enough to firmly hold the ladder rung within the “V” and prevents a twisting motion during transit.
In one embodiment, the front stop 40 may be a large square washer 1⅝″ by 1⅝″ that attaches to the strut 10 with standard mounting hardware and limits the forward motion of the front sliding mount 20. In one embodiment, the rear stop 46 may be a large square washer 1⅝″ by 1⅝″ that attaches to strut 20 with standard mounting hardware and limits the backward motion of the sliding mount 20. The elastic shock cord 60 provides the tension between the sliding mount 20 and the fixed mount 30.

The working portion 33 has a “V” shape that physically holds the rung or rung support the ladder notches to accommodate the ladder rungs when the ladder is stored with the sides vertical. This catch 33 is wide enough to firmly hold the ladder rung within the “V” and prevent a twisting motion during transit has a “V” shape on it's side that faces the receiving pin 26 and notches to accommodate the ladder rungs when the ladder is stored with the sides vertical. The adjustable catch could be made of a variety of materials. It could be made adjustable or non-adjustable for different types of ladders or other equipment. It could be built to look different but still perform the same task(s) and operate the same. It could be fastened to the fixed mount 30 in a variety of ways.
In one embodiment, the front stop 40 is a large square washer 1⅝″ by 1⅝″ it attaches to the strut with standard mounting hardware and limits the forward motion (sliding forward/away in front of the user) of the front sliding mount 20. The front stop 40 could be made of a variety of materials. It could be built to look different but still perform the same task(s) and operate the same. It could be fastened to the rail in a variety of ways. Other designs could eliminate the use of a stop entirely.
In one embodiment, the rear stop 46 is a large square washer 1⅝″ by 1⅝″ which attaches to the strut with standard mounting hardware and limits the backward motion (sliding toward the user) of the front sliding mount 20. The rear stop 46 could be made of a variety of materials. It could be built to look different but still perform the same task(s) and operate the same. It could be fastened to the rail in a variety of ways. Other designs could eliminate the use of a stop entirely.
In one embodiment, an elastic shock cord 60 provides the tension between the sliding mount 20 and the fixed mount 30. It could be made of varying size, strengths and material. There may be one or more cords 60. It could be replaced entirely with any device that provides the holding/return force required to operate the present invention.
The sliding mount 20 is inserted into the strut channel 10 where it is free to slide. The sliding mount 20 and the adjustable receiving pin 22 are connected together using a carriage bolt with a mating surface 28 on each to prevent slippage. The fixed mount 30 is attached to the surface of the strut channel. The fixed mount 30 and the adjustable catch 32 are connected together using a carriage bolt with a mating surface on each to prevent slippage. The front stop 40 and rear stop 46 are affixed to the strut channel 10 according to the position necessary for proper operation which will vary with different sizes and types of ladders. The shock cord 60 attaches between the sliding mount 20 and fixed mount 30 through holes or notches formed in each. The present invention could be built in various sizes. It could use differing materials for all parts. It could be altered to hold many different types of equipment aside from “A frame” ladders. The device providing holding tension could be any mechanism suitable to perform the task. This embodiment illustrates the 1⅝″ strut standard, any rail or strut dimension could be used provided the components are sized accordingly.
During use, as shown in FIGS. 4-6, the large tool hole found common in the top platform of an “A frame” ladder, is aligned with the receiving pin 26 that is attached to the sliding mount 20. The operator moves the ladder away from himself/herself which causes the sliding mount 20 to move along the rail toward the front stop 40. At this point the shock cord 60 is tensioning. As shown in FIG. 6, the sliding mount 20 hits the front stop 40 at which point the operator lifts the ladder and aligns the rung or rung support with the adjustable catch 33 which is fastened to the fixed mount 30. After alignment with the adjustable catch 33, the operator allows the tension of the shock cord 60 to return the ladder to the fully stowed position. To remove the ladder from the stowed position, simply reverse the process.
