TECHNICAL FIELD
The present disclosure broadly relates to the extendable tilt assembly system of cargo handling systems.
BACKGROUND
Cargo is transported in pickup trucks and other load carrying vehicles, trailers, etc. in order to move it from one location to another. Various types of cargo can include groceries, sports equipment yard waste, demolition waste, construction materials, tools, garbage, welders, compressors, fuel tanks and the like.
When placing cargo in the back of vehicles in the cargo bed, it is advantageous for a cargo handling system to be used which facilitates access to all parts of the cargo bed. Also of benefit is the ability to tilt cargo and dump it out when yard waste, demolition waste, gravel, aggregate work or garbage is hauled. The ability to remove various such items from the flush open end of the tailgate area or flush end of a trailer or load carrying vehicle by tipping one or more of the extendable assemblies is desirable, as is the ability for easily cleaning out (hosing out, sweeping, etc.) the cargo drawers used without over extending them or crazing into the cargo bed area.
The advantage of a cargo handling system is that it allows one to utilize the entire cargo bed area easily and effectively. Sometimes, however, the cargo bed in enclosed by a tonneau cover or topper adding to the difficulty of reaching transported cargo in the bed. And while pickup trucks remain quite popular, crossovers and other light vehicles are becoming more and more popular and are used more regularly to transport cargo under an enclosure.
When a type of cargo handling system is installed in the cargo bed area, flexible tilting of either drawer and the ability to clean out any remaining debris from the cargo transported is also necessary. Therefore, it is desirable to be able to tilt the drawers independently or together in order to release the transported cargo from both the lower drawer and upper drawer independently or affixed together. This cantilever function at the flush open end of the tailgate, or in instances where a tailgate is not present, provide one with the ability to turn any pickup truck, light load carrying vehicle, trailer, SUV, camper, etc. into a light dump truck. This feature is both of great advantage to the individual for ease of use and is economical.
For these reasons, U.S. Pat. No. 9,346,389 has been improved by modifying it in such a way that various embodiments of a new extendable tilt assembly system have been created.
SUMMARY
The present disclosure provides an Extendable Tilt Assembly System for vehicles by making improvements to U.S. Pat. No. 9,346,389 “Cargo Handling System”. The improvements are desirable in order to enable ease and flexibility for cleaning purposes of the system and in order to tilt, haul, load, and unload cargo from both the upper and lower extendable assemblies either together or independently. This improvement is necessary since in U.S. Pat. No. 9,346,389 in its current configuration, the lower extendable assembly is unable to tilt either to release loads or for proper and easy cleaning purposes. In addition, due to the various loads and equipment (e.g., auxiliary fuel tanks) that may be mounted in pickups or other light vehicles, this improvement is necessary to provide more configuration options that allows for the independent or continued use of the assemblies of the Cargo Handling System of U.S. Pat. No. 9,346,389.
This document provides for the creation of an Extendable Tilt Assembly System to provide interchangeability and flexibility to be able to be used/changed in/into various configurations based on various needs of the user. The Extendable Tilt Assembly System is created by adding a tailgate guide assembly and a modified guide assembly, a modified lower extendable assembly and a modified upper extendable assembly as modified and improved from U.S. Pat. No. 9,346,389; or, by using the tailgate guide assembly together with the cargo handling system of U.S. Pat.

DETAILED DESCRIPTION
FIG. 1 is a schematic rear perspective view showing tailgate guide assembly 141 and extendable tilt assembly system 101 in a retracted transport configuration secured to a cargo bed of a pickup truck 120 whereby the tailgate protector 268 with at least one upward facing tailgate guide runner 142, at least one removable or retractable lower catch member 360 and removable bar disposed adjacent to the back end of the tailgate guide assembly either fastened to a tailgate 140 or disposed over a bumper. In the case of a pickup, the tailgate is lowered/opened and horizontally flush with the cargo bed. When the tailgate is in position, the lower catch members 360 may be fixed in place or raised from a possible retractable or removable position to allow for either the modified lower extendable assembly 301 or modified upper extendable assembly 401 or both modified extendable assemblies to tilt.
Further details concerning the various sub-assemblies of the Extendable Tilt Assembly System will now be discussed in further detail.
FIG. 2A is a schematic top view of exemplary tailgate guide assembly 141 comprising a tailgate protector 268 which may be flat, formed, or bent (90 degrees or as needed) over top of tailgate with at least one guide runner 142, at least one removable or retractable lower catch member 360 and removable bar 361 added to it. The tailgate guide assembly may be affixed to a tailgate by fasteners 143.
The tailgate guide assembly 141 has both a top and bottom face and may fit over the inside face of a tailgate 140, or may rest over the bumper and, work as a continuation of the guide assembly of U.S. Pat. No. 9,346,389 or modified guide assembly. Guide runners 142 may be included in the guide assembly to facilitate tracking of the modified lower extendable assembly 301 or the modified upper extendable assembly 401 and/or to provide a more even surface for the extendable assembly(ies) to roll on. While three optional upward facing guide runners 142 on the tailgate guide assembly unit are shown in FIG. 2A any number of guide runners may be used and may be made out of any suitable material. Examples of suitable materials include, wood, metal (as used herein the term ‘metal’ includes pure metals and alloys), and plastics (e.g., low density polyethylene (LDPE), high density polyethylene (HDPE), polypropylene, and engineering thermoplastics).
The tailgate guide assembly 141 may be made of any suitable material preferably stiff enough to provide a useful degree of impact protection to the cargo bed. Examples of suitable materials include, plywood, metal, and plastics (e.g., low density polyethylene (LDPE), high density polyethylene (HDPE), polypropylene, and engineering thermoplastics.
FIG. 2B is a schematic bottom view and FIG. 2C is a schematic side view of exemplary tailgate guide assembly. The lower catch member(s) 360 may be positioned at one or more desired locations on the tailgate guide assembly 141 whereby a lower plate 363 may be fastened to the underside of the assembly with fasteners 143.
FIGS. 2D-2G The lower catch member(s) 360 engage(s) the upper catch members) 460 at the hook(s) 461 of the upper catch member(s) and at the bar(s) 361 of the lower catch member(s). The bar(s) 361 may be removable. The lower and upper catch members, bars, hooks, lower plates and fasteners 143 can be made of any suitable material. Examples of suitable materials include, wood, metal (as used herein the term “metal” includes pure metals and alloys), and plastics (e.g., low density polyethylene (LDPE), high density polyethylene (HDPE) polypropylene, and engineering thermoplastics).
Locking member 226 may lock (FIG. 3) either the modified upper or modified lower assembly, whichever is rolling on the upper facing guide runners 270 of which at least two or more upper facing guide runners 270 are on the modified guide assembly.
The locking holes 359 are for use with the modified upper extendable assembly independently rolling on the modified guide assembly 201 in order to secure the modified upper extendable assembly nearest the cab when rolling directly on the modified guide assembly.
There may be plurality of closeable top opening 251 positioned in the first and second inward facing channel 214, 224 of the modified guide assembly 201 to allow the stabilizer components of the modified lower extendable assembly and adjustable stabilizer components of the modified upper extendable assembly to be freed to allow the assembly to tilt when the lower catch members of the tailgate guide assembly engage with the upper catch members and hook portion attached on the lower bottom or upper bottom of either the modified lower extendable assembly or the modified upper extendable assembly.
The closure of the closeable top openings 251 may be made of any similarly strong material used to construct the inward facing channels 214, 224.
Plate(s) 462 (FIG. 4A) may be added and affixed to the modified lower extendable assembly 301 to provide strength for the addition of the upper catch member(s) 460 and hook portion 461 (FIG. 4B) may be positioned near the middle tilting point on the lower bottom of the modified lower extendable assembly. In order for the modified lower extendable assembly to pass over the upper catch member(s) 360 of the tailgate guide assembly 141 on the lower back end of the modified lower guide assembly cutouts 323 (FIG. 4A) may be made in such positions as to allow the passage of the modified lower extendable assembly to engage in a tilting position once the upper and lower catch members are engaged.
The upper catch member(s) 460 are positioned and are adapted to hingably engage the lower catch member(s) 360 and bar(s) 361, respectively (See FIGS. 6A, 6B, 6C, 7). While multiple upper and lower catch members are shown in the figures, single upper and/or lower catch members may also be used,
A plurality of upper tracking wheels 440 found in U.S. Pat. No. 9,346,389 on the upper bottom structure of the upper extendable assembly are affixed to the lower bottom structure of the modified lower extendable assembly (FIG. 4B) to track the modified lower extendable assembly. The upper tracking wheels of the modified lower extendable assembly roll on the upper facing runners of the modified guide assembly and across the tailgate facing guide runners of the tailgate guide assembly. The modified lower extendable assembly is guided in this embodiment by tracking wheels. A plurality of wheels 390 of the guide assembly of U.S. Pat. No. 9,346,389 continue to be present on the modified lower extendable assembly.
A stabilizer component 391 is added to the modified lower extendable assembly and it replaces the lower stabilizing wheels of U.S. Pat. No. 9,346,389 which are removed. An stabilizer component may be made of any suitable material and consist of any suitable component with or without wheels and may include a locking member to prohibit tilting until meeting the optional closeable cutout 251 part in the inward facing channel of the modified guide assembly. The stabilizer component may be of any shape (e.g., flat, round, square, oval, elongated, etc.) that fits inside the inward facing channel of the modified guide assembly. Present on the modified lower extendable assembly may be optional closeable cutout(s) 356, 358 (FIG. 4A) which may help to release the adjustable stabilizer components of the modified upper extendable assembly.
When the modified upper extendable assembly or modified lower extendable assembly (whichever is rolling directly on the tailgate facing guide runners of the tailgate guile assembly) and wherein when said at least one lower catch member and said at least one upper catch member are hingably engaged, the back end of either the modified lower extendable assembly or modified upper extendable assembly can tilt downward.
The upper catch member(s) 460 are sufficiently durable and/or reinforced that they can stand up to repeated use with heavy cargos and made of any suitable material.
A plurality of cross members may be added to the lower structure of the modified lower extendable assembly. The cross members may be made of any suitable material (e.g., metal, plastics, wood, etc.) to provide additional strength to the structure.
Upper extendable assembly 401 (FIG. 5) benefits from the addition of at least one adjustable stabilizer component 491. When the adjustable stabilizer component is positioned such that it aligns with the inward facing channels 214, 224 of the guide assembly 201, the adjustable stabilizer component may be released via the optional closeable top openings 251 and allow for the tilt of the modified upper extendable assembly to occur upon the engagement of the upper and lower catch members and hooks.
Thus, when the modified upper extendable assembly tilts, the adjustable upper stabilizer components may lift up and out of the first and second inward facing channels 214, 224. Preferably, the adjustable upper stabilizer component is of sufficiently small size that it does not contact the first and second inward facing channel surfaces in the retracted configuration of the modified upper extendable assembly; however, in extended configurations it may be capable of rollably travelling along the upper surface of the inward facing channels thereby preventing the upper extendable assembly from tipping prematurely (e.g., before the upper and lower catch members are engaged) when cantilevered out beyond the tailgate guide assembly 141. An adjustable upper stabilizer component is secured to the upper structure by any suitable means (e.g., brackets, bolts, clamps and/or welds). Preferably, an adjustable upper stabilizer component is made of any suitable material. In order for the modified upper extendable assembly 401 to work properly in this embodiment whereby the assembly rolls directly on modified guide assembly 201, the adjustable upper stabilizer component 491 may be adjusted. If it becomes desirable to use the modified upper extendable assembly directly rolling on the modified lower extendable assembly, the adjustable stabilizer component may be adjusted.
When driving, in normal position, there may be an additional locking member 444 affixed to the upper structure 410 of the modified upper extendable assembly 401 that engages with the second locking member 216, 226 on the modified guide assembly.
In this option (FIG. 6A) of the extendable tilt assembly system 101, the modified lower extendable assembly 301 rolls directly on the modified guide assembly 201 whereby it may continue out on the tailgate guide assembly 141 and the adjustable stabilizer components 391 release from the optional closeable top openings/cutouts 251 are positioned in the first and second inward facing guide channel 214, 224 while the upper and lower catch member(s) and hook(s) engage and allow for the tilt of the modified lower extendable assembly, provided the lower catch member(s) of the tailgate guide assembly are affixed in a ready to engage position (whereby the bar 361 is in position on the lower catch member 360 affixed to the tailgate guide assembly 141) to accept the upper catch member(s) and hook(s).
In this option (FIG. 6B) of the extendable tilt assembly system 101, the modified upper extendable assembly 401 may be attached and locked to the modified lower extendable assembly 301 which rolls directly on the modified guide assembly 201 whereby both the modified upper and modified lower extendable assemblies locked together and continuing out on the tailgate guide assembly 141 activate the tilting of the modified lower extendable assembly as stabilizer components 391 release from the optional closeable top openings/cutouts 251 positioned in the first and second inward facing guide channel 214, 224 while the upper and lower catch member(s) and hook(s) engage and upon the engagement of the upper and lower catch member(s) and hook(s), provided the lower catch member(s) of the tailgate guide assembly are affixed in a ready to engage position (whereby the bar 361 is in position on the lower catch member 360 affixed to the tailgate guide assembly 141) to accept the upper catch member(s) and hook(s).
In this option (FIG. 6C-6D) of the extendable tilt assembly system 101, the modified upper extendable assembly 401 rolls directly on the modified guide assembly 201 whereby the modified upper extendable assembly continues out on the tailgate guide assembly 141 to activate the tilting of the modified upper extendable assembly, the locking member 226 disengages from locking member 444 and as it moves to the cantilever position, the adjustable stabilizer components 491 release from the optional closeable top openings/cutouts 251 positioned in the first and second inward facing guide channel 214, 224 while the upper and lower catch member(s) and hook(s) engage and upon the engagement of the upper and lower catch member(s) and hook(s), provided the lower catch member(s) of the tailgate guide assembly are affixed in a ready to engage position (whereby the bar 361 is in position on the lower catch member 360 affixed to the tailgate guide assembly 141) to accept the upper catch member(s) and hook(s).
In this option (FIG. 6E) of the extendable tilt assembly system 101, the modified upper extendable assembly 401 rolls on the modified lower extendable assembly 301 which in turn rolls directly on the modified guide assembly 201 and tailgate guide assembly 141. In this instance, tilting may occur by engaging the lower and upper catch member(s) and hook(s) of the modified upper and modified lower extendable assemblies of the Cargo Handling system of U.S. Pat. No. 9,346,389 whereby the modified lower extendable assembly is out at the flush open end of the tailgate or slightly beyond and its lower catch member facilitates the tilt feature in a similar manner as described in U.S. Pat. No. 9,346,389.
A extendable tilt assembly system 101 (FIG. 7) comprising of a tailgate guide assembly 141 may be configured together with the cargo handling system of U.S. Pat. No. 9,346,389 whereby the removable or retractable lower catch members 360 and bars 361 are removed from the tailgate guide assembly. When this occurs, the cargo handling system of U.S. Pat. No. 9,346,389 consisting of a guide assembly 200, a lower extendable assembly 300 and an upper extendable assembly 400 as described and with all applicable claims of U.S. Pat. No. 9,346,389 can benefit from the tailgate guide assembly upon which the lower extendable assembly may continue to roll upon. The tailgate facing guide runners of the tailgate guide assembly may accept the wheels of the lower extendable assembly. All parts, movement and functionality of the cargo handling system of U.S. Pat. No. 9,346,389 is fully retained with the presence of a tailgate guide assembly which may be affixed by any appropriate means to a tailgate when present, or may rest over a bumper in the absence of a horizontal tailgate.
An extendable tilt assembly system 101 (FIG. 8A) comprising a further modified guide assembly 201a together with a modified upper extendable assembly 401. Alternatively the further modified guide assembly 201a may have a modified lower extendable assembly 301 roll upon it. The further modified guide assembly 201a may facilitate a tilting function of either the modified upper extendable assembly or the modified lower extendable assembly or both by adding at least one removable or retractable lower catch member 360 and at least one removable bar 361 disposed adjacent to the back end of the further modified guide assembly, and optional closeable cutout area 251 may be added which releases the stabilizer components and/or adjustable stabilizer components. Facilitating the tilt feature of either the modified upper extendable assembly or the modified lower extendable assembly rolling directly on the further modified guide assembly or both locked together rolling on the further modified guide assembly. Upon tilting, the removable or retractable lower catch member 360 and removable bar 361 engage with the one or more upper catch members 460 and hook(s) 461.
The front view (FIG. 8B) of the tilt guide assembly 201a is highlighting the removable or retractable lower catch members 360 and removable bar 361 fastened directly to the modified guide assembly. This version of the extendable tilt assembly system, may be used when no horizontally extended tailgate and/or bumper is present, such as with a trailer, camper, or other light vehicle.
