DESCRIPTION
Certain exemplary embodiments can provide a system, machine, device, manufacture, configured for, relating to, and/or resulting from, and/or a method for activities that can comprise and/or relate to, extending a floor, such as a floor of deck, patio, platform, and/or a vehicle, such as a trailer and/or truck from a compressed arrangement to an extended arrangement.
Certain exemplary embodiments can provide systems, devices, and/or methods for managing the length of a trailer, such as a gooseneck trailer, a bumper pull trailer, and/or a fifth wheel, etc.
As shown in the attached figures, certain exemplary embodiments can provide a trailer that is configured to have an extendable length. A substantial portion of the extension mechanism can be located at or near the front of the trailer.
Via certain exemplary embodiments, extension of the trailer can be accomplished by unfolding two or more folded flooring modules of a foldable floor assembly. The foldable floor assembly can be located at or near the front of the trailer. The foldable floor assembly can be structurally supported by, and/or can bear on, one or more substantially horizontally-extending folding floor support assemblies that can be configured to extend in a direction substantially parallel to the length of the trailer.
In certain exemplary embodiments, unfolding of the foldable floor assembly can be assisted by engagement with a gravity-returned operating cam. For example, an un-folding of the foldable floor assembly can be initiated by a nudge provided from a partial rotation a manually operated cam. The foldable floor assembly can expand to form a floor of approximately 2 feet to approximately 20 feet (including all values and sub-ranges therebetween), such as approximately 8 feet in length. The foldable floor assembly can fold at regular and/or irregular intervals, such as into two four foot half-sections (the flooring modules) connected to each other via a common center hinge, and/or connected to the trailer via a single head hinge. For example, the foldable floor assembly can comprise two 4′×8′× 3/16′′ (or 1⁄4′′ or 1⁄8′′ depending on, e.g., load) diamond plate steel floor plates.
Each hinge can be fabricated of 2′′ schedule 40 pipe with 2′′ slot welded slugs, and a common arrangement hinge at the head of the folding assembly. The front-most plate can tethered to the main trailer bed by 3/16′′ or 1⁄4′′ gauge chain. Each hinge can be welded to the backside of the plates. Each hinge can be greasable with a thread-in grease fitting.
The folded flooring modules can be mechanically connected to one another and/or to a stationary portion of the trailer floor (e.g., the folding floor support assemblies) via one or more hinges. The foldable floor assembly can be tethered to the main trailer bed, potentially by chain that can be used to pull its folded flooring modules into a substantially open, flat, and/or horizontal position. The opening process can involve using the trailer braking system to substantially anchor the rear portion of the trailer while the tractor or motorized vehicle attached to the trailer pulls the front of the trailer forward, thereby providing a lengthening or extending force to the trailer.
Alternatively, or in addition, the foldable floor assembly can be extended and/or opened via positioning one or more wheel chock in front of one or more of the trailer wheels, thereby preventing those wheels from easily rotating forward, while pulling the trailer hitch forward, thereby pulling the front of the trailer with respect to the back of the trailer and/or pulling an first floor support (potentially connected to the trailer hitch) with respect to a second floor support (potentially connected to the wheel). When compressing the foldable floor assembly, the one or more wheel chocks can be relocated to behind the one or more wheels, thereby providing rolling resistance to those wheels while the hitch is pushed toward those wheels.
Alternatively, or in addition, the foldable floor assembly can be extended and/or opened via a more localized actuation system, which can rely on any known mechanism configured for extending length, e.g., a linear actuator, such as a screw, wheel and axle (e.g., hoist, winch, rack and pinion, chain drive, belt drive, etc.), articulating arm, cam and follower, hydraulic and/or pneumatic piston/cylinder, etc. The linear actuator can be manual and/or powered, such as via a hand crank, rotary and/or linear motor, hydraulic pump, pneumatic compressor, moving coil, etc.
When the foldable floor assembly is not in an extended orientation, it can be folded into and/or retained in a substantially upright and/or vertical folded orientation. The retention of the foldable floor assembly in the substantially upright orientation can be accomplished by any suitable approach, such as via one or more retention pins, locks, hasps, hooks, latches, magnets, etc. For example, the foldable floor assembly can be retained in the substantially upright orientation by two 1′′ inch spring returning retaining pins.
Certain exemplary embodiments of the folding floor support assembly(ies) can comprise two or more nested tubes or tube-like structures, where at least one tube can slide lengthwise with respect to another. In longitudinal cross-section, the tubes can have an inner or outer perimeter of any desired shape. For example, any of the tubes can have a substantially longitudinal cross-section that is substantially rectangular, square, oblong, ellipsoidal, round, D-shaped, etc., in its outer perimeter and/or inner perimeter.
The support assemblies need not comprise closed polygons. For example, two or more support assembles can interact and/or interconnect via interlocked members having a longitudinal cross-section that is C-shaped, L-shaped, V-shaped, T-shaped, I-shaped, etc. For example, one or more rectangular members can be partially enclosed by a C-shaped outer member. As another example, one V-shaped member can rest and/or bear upon another. As yet another example, a square tube can have a slot cut in it through which the web of a T-shaped member extends and the cap, top, or flange of the T moves within the hollow of the tube. The width of the slot can be less than the width of the flange, thereby slideably interlocking the flange within the tube.
Thus, the two or more support members need not be of similar shape. That is, one member can be scaled-up in one or more dimensions with respect to another. Moreover, regardless of dimensions, one member can have a substantially different longitudinal cross-sectional shape than another. The two or more support members need not be of equal length.
The support members can be utilized with trailers having an extended length of from approximately 4 feet to approximately 60 feet (including all values and sub-ranges therebetween) and with a foldable floor assembly that can add from approximately 2 feet to approximately 20 feet (including all values and sub-ranges therebetween) to the length of the un-extended trailer. The interface between any two support members can be greased to reduce friction created when one tube slides with respect to the other.
The dimensions and/or materials of the support assemblies can be varied to suit the anticipated use, expected loads, and/or extended length of the trailer.
One or more outer support members can comprise a slot, groove, and/or channel extending into and/or through one or more of its sidewalls, the channel extending all or a portion of the length of an outer support member, such as from approximately 10 percent to approximately 100 percent (including all values and sub-ranges therebetween) of the length of an outer support member, the channel starting at one end or inset by a predetermined amount. Through and/or into the channel can extend a fin, blade, or web of an inner support member, the fin extending from approximately 10 percent to approximately 100 percent (including all values and sub-ranges therebetween) of the length of the inner support member.
The fin/channel assembly can be configured to limit a travel of an inner support member with respect to an outer support member. For example, assume two nested tubes, the outer tube having a substantially identical, rectangular longitudinal cross-section to the inner tube, except the cross-section of the outer tube is enlarged with respect to the inner tube such that the inner tube can achieve a running and/or relatively easily slideable fit within the other. Assume the outer tube is 30 feet long and the inner tube is 20 feet long. Assume the outer tube has a slot extending completely through one of its sidewalls and longitudinally extending for 12 feet along that tube beginning approximately 2 feet from the front end of that tube. Assume the inner tube has a longitudinally extending 10 foot long fin that extends perpendicularly from one sidewall, begins approximately 2 feet from the front end of that tube, and is aligned to extend completely through the slot of the outer tube. By virtue of the slot not extending to either end of the outer tube, the fin of the inner tube can be “trapped” within that slot, thereby preventing and/or resisting the inner tube from escaping or being pulled free from the outer tube (and vice versa), yet allowing the inner tube to relatively easily slide within the constraints imposed by the outer tube.
In certain exemplary embodiments, two nested rectangular tubes can be formed from hot rolled structural steel having 3⁄8′′ wall thickness. The inside rectangular tube can have a 1⁄2′′×12′′ or 24′′×1⁄2′′ fin or blade passing through a laser or plasma cut slot cut in a 1⁄4′′×8′′, 10′′, or 12′′ tube to 15′′ at 5/16 gauge. The slot can match the length of the tube so that the inner tube can be inserted into the outer tube from the back of the trailer. The inner tube can be cut longer than the outer tube to accept the welding of a gooseneck towing support frame.
A dust and/or road shield can be installed over the slot to help prevent debris from entering the slot and/or interfering with the free sliding of the support members relative to each other.
The support member assembly can be assembled in a welding jig as a five piece assembly, with a gap set between all the pieces of approximately 0.00015 to approximately 0.00025 thousands of an inch for weld shrinkage. The assembly can be tacked together in a specific pattern and welded with a pattern to control shrinkage and/or provide substantially uniform straightness.
Certain exemplary embodiments can provide systems, devices, and/or methods for managing the length and/or area of a floor, such as a deck, patio, and/or platform, and/or such as found on a vehicle, such as a gooseneck trailer, bumper pull trailer, fifth wheel, panel truck, and/or van, etc.
FIGS. 1A-D show a perspective, top, front, and side view, respectively, of an exemplary embodiment of a machine 1000 in an extended arrangement. FIGS. 1E-H show a perspective, top, front, and side view, respectively, of an exemplary embodiment of a machine 1000 in a compressed arrangement. Although resembling a portion of a bumper-pull trailer, more generally exemplary machines can be any vehicle, such as a gooseneck trailer, bumper pull trailer, fifth wheel, panel truck, and/or van, etc., and even more generally can be any extendable floor, such as a deck, patio, and/or platform, etc.
As shown, machine 1000 can comprise one or more elongated and substantially “fixed” floor supports 1100, one or more elongated and extendable floor supports 1200, one or more substantially “fixed” floors 1300, one or more extendable floors 1400, one or more substantially “fixed” rails 1500, one or more extendable rails 1600, and/or a hitch assembly 1700. Although not shown, machine 1000 can comprise one or more wheels, the rotation of which substantially define a travel direction of machine 1000. In the context of this application, the phrase “fixed” refers to an element that, when in its intended use, does not substantially move, such as in the travel direction, with respect to another element, such as an axis of rotation of one or more of the wheels.
FIG. 2A is a side view of an exemplary embodiment of a machine 2000 in an extended arrangement, and FIG. 2B is a side view of an exemplary embodiment of a machine 2000 in a compressed arrangement.
As shown, machine 2000 can comprise an elongated substantially “fixed” floor support 2100, an elongated extendable floor support 2200, a substantially “fixed” floor 2300, an extendable floor 2400 assembly, and/or a hitch assembly 2700. As shown, machine 2000 can comprise one or more wheels 2800, the rotation of which substantially define a travel direction of machine 2000. Extendable floor assembly 2400 can comprise flooring modules 2420, 2440 that are connected to each other via a hinge 2460 and/or connected to extendable floor support 2200 via a hinge 2480. Protrusion 2220 can protrude from extendable floor support 2200 and through and be trapped by an elongated slot 2120 defined in fixed floor support 2100. As extendable floor support 2200 moves and extends relative to fixed floor support 2100, protrusion can slide along slot 2120, potentially between a fully compressed slot terminus 2130 and a fully extended slot terminus 2140.
FIG. 3 is a side view of an exemplary embodiment of a machine 3000 in an extended arrangement. Protrusion 3220 is shown protruding from extendable floor support 3200 and through elongated slot 3120 defined in fixed floor support 3100.
FIG. 4 is a side view of an exemplary embodiment of a machine 4000, showing a portion of an extendable flooring module assembly 4200 in an extended arrangement. Flooring module 4220 can connect to flooring module 4240 via a hinge (not shown). Flooring module 4220 can slant and/or be angled at an angle M with respect to horizontal and/or an extendable floor support (not shown). Flooring module 4240 can slant and/or be angled at an angle N with respect to horizontal and/or an extendable floor support (not shown). Angle M can be, but need not be, identical to angle N, and either angle can vary from approximately 0.5 degrees to approximately 5 degrees, including all values (e.g., 1.02, 1.5, 2, 2.3, 2.512, 3, 3.33, 3.999, etc. degrees) and sub-ranges therebetween. Angling flooring modules slightly can help lock them in place in the extended arrangement.
FIG. 5 is a side view of an exemplary embodiment of a machine 5000, showing an extendable flooring module assembly 5400 in a partially extended arrangement (i.e., between an extended arrangement and a compressed arrangement). Flooring module 5420 can connect to flooring module 5440 via a hinge 5460, to a shaft 5490 of which can be connected a cam 5450 and/or a handle 5470. Extendable floor support 5200 is shown partially extended with respect to fixed floor support 5100. A notch and/or cavity 5250 in extendable floor support 5200 can, when extendable flooring module assembly 5400 is in an extended arrangement, accommodate and store cam 5450 and hinge 5460 below a plane defined by floor module 5420 and below a plane defined by floor module 5440. From the extended arrangement, handle 5470 can rotate cam 5450 such that cam 5450 follows a contour bearing against cavity 5250 in a manner that causes shaft 5490 to rise, thereby lifting hinge 5460 and allowing floor module 5420 and 5440 to fold toward each other about hinge 5460 and/or allowing extendable flooring module to fold from an extended arrangement into a compressed arrangement.
FIG. 6 is an end view of an exemplary embodiment of an assembly 6000, which can comprise a first floor support 6100, a second floor support 6200, and a third floor support 6150. Attached to second floor support 6200 can be a protrusion 6120, which can be slideably trapped in a slot in first floor support 6100, thereby potentially allowing second floor support 6200 to slide, move, and/or extend relatively to first floor support 6100. Third floor support 6300 can be rigidly attached to first floor support 6100 or second floor support 6200 or neither. As shown, first floor support 6100 can comprise a unitary C-shaped structural member.
FIG. 7 is an end view of an exemplary embodiment of an assembly 7000, which can comprise a first floor support 7100, a second floor support 7200, and a third floor support 7300. Attached to second floor support 7200 can be a protrusion 7120, which can be slideably trapped in a slot in first floor support 7100, thereby potentially allowing second floor support 7200 to slide, move, and/or extend relatively to first floor support 7100. Third floor support 7300 can be rigidly attached to first floor support 7100 or second floor support 7200 or neither. As shown, first floor support 7100 can comprise a substantially vertical plate that is attached to perpendicular substantially horizontal plates.
FIG. 8 is an end view of an exemplary embodiment of an assembly 8000, which can comprise a first floor support 8100 and a second floor support 8200 nested within first floor support 8100. Attached to second floor support 8200 can be a protrusion 8120, which can be slideably trapped in a slot in first floor support 8100, thereby potentially allowing second floor support 8200 to slide, move, and/or extend relatively to first floor support 8100. As shown, first floor support 8100 can comprise a substantially C-shaped structural member that is attached to a substantially vertical plate.
FIG. 9 is a side view of an exemplary embodiment of an assembly 9000, which can comprise a first floor support 9100 that defines a slot 9120 through which a protrusion 9220 of a second floor support can protrude, be trapped, and/or be slideably received.
FIG. 10A is a side view of an exemplary embodiment of a machine 10000 in between a compressed arrangement and an extended arrangement, and FIG. 10B is a side view of an exemplary embodiment of a machine 10000 in a compressed arrangement. As shown, when transitioning from an extended arrangement to a compressed arrangement, extension railing 10600 can rotate such that it is supported by fixed railing 10500.
FIG. 11 is a side view of an exemplary embodiment of an assembly 11000, which can comprise a first floor support 11100, a second floor support 11200. Attached to second floor support 11200 can be a protrusion 11220, which can be in the shape of a pin, blade, bar, etc., can be attached to extendable floor support 11200, can protrude through slot 11120 in fixed floor support 11100, and/or can be slideably trapped in a slot in first floor support 11100, thereby potentially allowing second floor support 11200 to slide, move, and/or extend relatively to first floor support 11100 in a controlled manner.
Assembly 11000 is shown approaching a compressed arrangement. As shown, as machine 11000 and/or protrusion 11220 approaches the compressed arrangement, protrusion 11220 can press against a latch assembly 11800, which can comprise a rotatable and biased latch 11820 mounted on a latch shaft 11840 (which defines a latch rotational axis) and connected to a torsional spring and a flexible latch handle 11860. In certain exemplary embodiments, latch handle 11860 can comprise a proximal portion 11862 that is configured to be grasped by a user of the handle, a distal portion 11866 that is configured to directly connect to latch 11820, and a flexible portion 11864 that is configured to flexibly join proximal portion 11862 and distal portion 11866. To prevent latch 11820 from inadvertently releasing protrusion 11220, proximal portion 11862 can be configured to be captured between handle restrainer 11870, such as a top pin 11872 and handle bottom pin 11874, thereby restraining and/or limiting movement of handle 11860 and thus latch 11820.
When approaching the compressed arrangement, and as protrusion 11220 presses against the front-most portion of latch 11820, that pressure can overcome the counter-clockwise torsional bias of a torsional and/or helical spring that has a longitudinal axis that is substantially co-incident, parallel to, and/or aligned with a rotational axis of latch 11820 and/or shaft 11840. Thus, the pressure applied by protrusion 11220 pressing against the front-most portion of latch 11820 can lift latch 11820 sufficiently for protrusion 11220 to fit within and, due to the counter-clockwise bias provided by the helical spring, be captured by latch 11820. Because handle 11860 can be flexible, proximal portion 11862 need not be released from handle retaining pins 11872 and/or 11874 for protrusion 11220 to be captured by latch 11820, but instead handle 11860 can flex sufficiently to allow the latch shaft to rotate clockwise when protrusion 11220 applies sufficient force in the rearward direction against latch 11820.
To release machine 11000, protrusion 11220, and/or latch 11820 from the compressed arrangement, the proximal portion 11862 of flexible latch handle 11860 can be moved away from first floor support member 11100, thereby flexing flexible portion 11864 of handle 11860 and allowing proximal portion 11862 of handle 11860 to slide over and/or around handle top pin 11870, thereby allowing handle 11860 to rotate about latch rotational axis clockwise to rotate and lift the front portion of latch 11820 so that protrusion 11220 is released from latch 11820 and can freely slide in slot 11120. A latch rotation stop 11880 can prevent latch 11820 from rotating clock-wise beyond a predetermined limit.
FIG. 12A is a side view of an exemplary embodiment of a latch assembly 12000, which can comprise a handle 12100 having a proximal portion 12200 that is configured to be operably grasped by a user of latch assembly 12000, a distal portion 12400 that is configured to apply a torque and or moment about a rotational axis of a latch shaft 12500, and thereby against latch 12600, and a flexible portion 12300 that flexibly connects proximal portion 12200 and distal portion 12400. Note that, as shown, latch 12400 is configured to capture a protrusion that has a blade-like and/or bar-like configuration.
FIG. 12B is an end view of an exemplary embodiment of a handle 12100, showing how flexible portion 12300 can be formed from, e.g., a hose and/or helical spring and can connect a proximal portion 12200, such as, e.g., a tube having a square and/or circular longitudinal cross-section, to a distal portion 12400, which can have a structure that is similar to or different from that of proximal portion 12200.
FIG. 13 is a side view of an exemplary embodiment of a latch 13000 that is configured to capture a protrusion having a pin-like configuration.
FIG. 14A is a side view of an exemplary embodiment of a machine 14000 in a compressed arrangement. Machine 14000 can comprise one or more first floor support members 14100, one or more second floor support members 14200, one or more third floor support members 14300, an extendable flooring assembly 14400, and/or a vehicle 14500 from which extendable flooring assembly can fold and/or extend, such as from a side, back, and/or front of vehicle 14500.
FIG. 14B is an end view of an exemplary embodiment of machine 14000 in a compressed arrangement, and showing that extendable flooring assembly 14400 can fold-up very close to vehicle 14500.
FIG. 14C is an end view of an exemplary embodiment of machine 14000 in an extended arrangement, and showing that second floor support 14200 can extend away from vehicle 14500 and/or be supported by third floor support 14300.
