Definitions

  • the invention relates to a mechanical device used to retain cargo being stored or transported in the cargo area of a vehicle, in particular, the cargo bed of a pick ⁇ up truck.
  • a mechanical device that retains cargo that is stored or transported in the cargo area of a vehicle, in particular, the cargo bed of a pick-up truck.
  • the device can be used in other applications, for example, in the interior cargo area of a sport utility vehicle or van, or on the roof of a vehicle.
  • the device disclosed herein can generally be described as a cargo clamp.
  • the cargo clamp according to the preferred embodiment includes three main components: (1) a clamp arm assembly, (2) a pair of ratchet assemblies, and (3) a pair of mounting track assemblies.
  • the clamp arm assembly includes a pair of arms extending along the length of the pick-up truck bed, i.e. , in a direction oriented from the front to the back of the vehicle (from the cab-end of the truck towards the tailgate) or vice versa having a loading section connected to the arms.
  • the clamp arm assembly is mounted to the pair of ratchet assemblies via each ratchet assembly's gear shaft.
  • the ratchet assemblies are adjustably attached to the mounting tracks.
  • the mounting tracks are, for example, mounted along the tops of the vertical sides of the pick-up truck bed. The position of the ratchet assemblies can be adjusted along the length of the mounting track assemblies. Once in the appropriate position, the ratchet assembly can be locked into position.
  • the clamp arm assembly is rotatably attached to the gear shaft of each ratchet assembly.
  • the clamp arm assembly freely rotates about the gear shaft to allow the clamp arm assembly to initially engage cargo resting in the truck bed, after which the ratchet assemblies are engaged and operated to increase the restraining force on the cargo, retaining it against the surface of the truck bed, the front or rear of the truck bed, or an opposing cargo clamp.
  • the ratchet assemblies are geared to provide a torque gain such that a reasonable hand-applied force produces a downward force adequate to hold a heavy load.
  • a plurality of assemblies can be mounted to the tracks of the same pickup truck (e.g., one near the cab and one near the tailgate), allowing for greater capacity, and versatility.
  • dual cargo clamp assemblies can retain a load between themselves, applying primarily horizontal, instead of primarily vertical, force/retention.
  • the device is beneficial in its ability to quickly and effectively retain a cargo for transport in a pick-up truck or other vehicle, and quickly release it for removal at its destination.
  • the invention is beneficial in that it is easily adjustable to accommodate a variety of cargo types. It provides superior capacity and simplicity of use compared with conventional alternatives, such as tying or banding the load, or utilizing "dividers” or other similar devices aimed at making the truck bed "fit” the load being carried. In addition to its simplicity and superior functionality for load holding, it is also easily left on the pick-up in a "storage” position, or can easily be removed from the sliding tracks, leaving only the unobtrusive tracks permanently installed on the vehicle.

  • the cargo clamp 1 has three main components: (1) a clamp arm assembly 100, (2) a pair of ratchet assemblies 200, and (3) a pair of track assemblies JUU. The arrangement and function of each of these components will be described in detail in the following paragraphs.
  • the clamp arm assembly applies the required clamping load to prevent a cargo from moving about a vehicle's cargo area.
  • Cargo clamp 1 achieves this by transferring a torque load from the ratchet assemblies 200 through the clamp arm assembly 100 to the cargo.
  • clamp arm assembly 100 is a generally U-shaped member connected to ratchet assemblies 200 at a gear shaft 206 shown in Figure 2.
  • a torque is transferred from the ratchet assemblies 200 through gear shaft 206. This torque can then be applied to a variety of cargo to secure the cargo to or within a vehicle.
  • Clamp arm assembly 100 is, in one embodiment, composed of several components that may be assembled to form the clamp arm assembly 100.
  • clamp arm assembly 100 can include a pair of side arm members 101, a pair of corner members 102, and a cross bar member 103.
  • a cross bar cover 104 also can be included in some embodiments.
  • the members 101, 102, 103 can be attached by any number of well known methods, for example, by bolting. Such a multi-component construction of clamp arm assembly 100 allows for more convenient shipping of a clamp arm 1 to customers and more convenient storage of the clamp arm 1 (because the disassembled clamp arm assembly 100 takes up less space than the assembled clamp arm assembly 100).
  • the members 101, 102 and 103 can be attached to one another by other methods, such as welding, for example.
  • the invention is not limited to a multi- component clamp arm and can include other variations such as a one-piece clamp arm assembly, for example.
  • the clamp arm assembly 100 is made of steel tubing, however, other well known materials, such as other metals, e.g., aluminum, plastics, etc. can be used. Members having different sections can also be used.
  • Clamp arm assembly 100 is, in one embodiment, removably attached to gear shaft 206 of ratchet assemblies 200 by a retaining knob 225. Such removable attachment allows for the clamp arm assembly 100 to be conveniently removed when not in use. This removability also allows for different clamp arm assemblies to be utilized. For example, a clamp arm assembly could be installed that is designed specifically to hold bicycles. However, when a user desires to restrain a cargo other than a bicycle, the bicycle-specific clamp arm assembly could be removed and replaced with the multi ⁇ purpose clamp arm assembly illustrated in Figure 1. The invention is not, however, limited to removable clamp arm assemblies and a clamp arm assembly could be permanently attached to ratchet assembly 200 or attached in another manner.
  • ratchet assembly 200 shown in Figures 1 and 2 will be described.
  • the ratchet assembly includes bracket 215 which has disposed thereon a ratcheting mechanism 220.
  • Ratcheting mechanism 220 includes a gear shaft 206 which is connected to clamp arm assembly 100.
  • Ratcheting mechanism 220 allows a user to rotate a handle 228 in a cargo-loading direction to apply a torque to the cargo.
  • the ratcheting mechanism 220 then holds the gear shaft to prevent it from rotating, thereby allowing a user to freely rotate the handle in the opposite direction without removing the torque previously applied.
  • Ratchet assembly 200 applies the torque force to the clamp arm assembly 100, and, consequently, to a cargo. To achieve this, a user applies force to handle 228 which becomes a torque in gear shaft 206. This resulting torque is then transferred through the ratchet assemblies 200 and applies the clamping load to a cargo. To release the clamping load from the cargo the user releases the ratcheting assemblies 200.
  • All components of the ratchet assemblies 200, except for the ratchet assembly cover 212F, are, in one embodiment, made of steel. However, other materials, such as other metals or plastics, could be used.
  • Each track assembly is comprised of an upper rail 301 and a lower rail 302.
  • Rails 301, 302 are formed in or mounted to the top of the gunwales of the vehicle cargo area.
  • Lower rail 302 is attached to the vehicle, for example, along the gunwales of a pick-up truck bed. Any number of well known methods of attachment can be used to secure lower rail 302 to the vehicle, for example, screwing, bolting, welding, or rivets can be used. However, here, countersunk screws are used to provide a removable attachment to the vehicle and to provide a flush fit with a top surface of lower rail 302.
  • Upper rail 301 is attached to the lower rail 302. Upper rail 301 is wider than lower rail 301 , thereby creating a lip or overhang.
  • a mounting bracket 303 has flanges along the longitudinal edges of the bracket, as shown in Figure 3. The flanges of mounting bracket 303 fit over the lip forjned by the upper and lower rails, thereby securing the mounting bracket 303 to upper rail 301 , while, at the same time, allowing the mounting bracket 303 to slidably move along the length of upper rail 301.
  • Mounting bracket 303 is a substantially C-shaped channel section as illustrated in Figure 3. Accordingly, a user may adjust the position of cargo clamp 1 along the length of the cargo area.
  • a slide prevention mechanism 210 locks the cargo clamp 1 in position along upper rail 301.
  • the slide prevention mechanism has a lever extending through bracket 215 and cover 212. The lever is connected to a plunger and a plunger pin. When a user moves the lever to an adjustment position, the plunger pin is raised, thereby allowing cargo clamp 1 to move along upper rail 310. When the lever is moved to the locked position, the plunger pin engages upper rail 301 , thereby prevent cargo clamp 1 from sliding along upper rail 301.
  • a rotation prevention unit 230 prevents undesired rotation of handle 228.
  • the rotation prevention unit can include, in a preferred embodiment, a pin 229 engaged with handle 228 that is configured to engage bracket 215 to prevent rotation of handle 228. To allow the handle to rotate, the pin 229 is removed from engagement with bracket 215, thereby allowing the handle to rotate.
  • the cargo clamp 1 is then assembled to upper track 301 by sliding each ratchet assembly 200 onto either end of the upper track 301.
  • Cargo clamp 1 can be installed with the clamp arm 100 clamping toward the front or rear of the vehicle. Adjusting the position of cargo clamp 1 allows the operator to avoid obstructions in the cargo area such as a wheelhouse and offers much versatility to the function of the cargo clamp 1.
  • An additional benefit of the mounting tracks assembly as described herein is that a plurality cargo clamps 1 can be mounted at the same time offering even more versatility.
  • the rails 301 , 302 would be fastened longitudinally to the top of the cargo area gunwale on both the left and right sides of the truck. Track mounting as disclosed herein provides for adjustability in the positioning of the cargo clamp 1 for various loading scenarios.
  • the rails 301, 301 and mounting bracket 303 can be omitted.
  • the ratchet assemblies 200 can be mounted directly to the vehicle without use of the tracks 301.
  • tracks 301. 302 can be mounted to the cargo bed of the pickup truck.
  • the mounting tracks 12 could be integrally formed with a pick-up truck's gunwales. While a pick-up truck mounting configuration has been described, the cargo clamp can be mounted on a number of different vehicles in a variety of different locations.
  • a cargo clamp 1 , without or without track assembly 300 could be mounted on the roof of a car to, for example, secure skis, surfboards, or bicycles.
  • Figure 4 illustrates an alternative embodiment of a cargo clamp.
  • the cargo clamp illustrated in Figure 4 has four main components: (1) a pair of clamp arm assemblies, each of which includes a clamp arm 410 and, in certain embodiments, a swing arm 411, (2) a pair of ratchet assemblies 415, (3) a crossbar 413, and (4) a mounting track assembly 412.
  • a pair of clamp arm assemblies each of which includes a clamp arm 410 and, in certain embodiments, a swing arm 411
  • a pair of ratchet assemblies 415 a pair of ratchet assemblies 415
  • a crossbar 413 a crossbar 413
  • mounting track assembly 412 The arrangement and function of each of these components will be described in detail in the following paragraphs.
  • the crossbar 413 is attached to the two swing arms 411 that are rotatably attached to the clamp arms 10.
  • the swing arms 411 allow the distance between the ratchet assemblies 415 and crossbar 413 to be adjusted.
  • maximum load is transferred to the crossbar 413.
  • By rotating the crossbar 413 to the longer distance maximum reach is achieved at the loss of some load capacity.
  • a flange 418 extends perpendicular to the swing arm 41 1. The flange 418 prevents further rotation of the swing arm 411 by abutting against the clamp arm 410.
  • the swing arms 411 could be omitted by attaching the crossbar 413 directly to the clamp arms 410.
  • the crossbar 413 can be covered by a crossbar sleeve 416.
  • the crossbar sleeve 416 can be triangular in section and fits onto crossbar 413.
  • Crossbar sleeve 416 is made of a soft core with a rubber coating which helps the crossbar 413 grip cargo. However, other materials can be used, or the crossbar sleeve 416 could be omitted entirely.
  • FIG. 5 provides a perspective view of another embodiment of a ratchet assembly 415.
  • the ratchet assembly 415 applies the required force to the crossbar 413, and consequently, the cargo. It maintains that force until the user desires to release the force.
  • the user applies force to a ratchet lever 520 which becomes a torque in a clamp arm shaft 527. This resulting torque is then transferred through the clamp arm assembly and applies the clamping load as described above.
