1. Technical Field
The present invention relates generally to lifts used in various types of motor vehicles and the like.
2. Description of Related Art
It often is desirable to assist a user in lifting cargo into and out of motor vehicles, such as minivans, hatchback motor vehicles, etc. In particular, many people use motor vehicles to transport mobility devices such as scooters, power chairs and the like. A number of earlier lifts and accompanying systems are mountable in the cargo and/or storage area(s) of such motor vehicles.
Current vehicle lifts provide two types of securement. “Active” securement systems typically require manual attachment of belts or straps to the mobility device or other cargo. In such active securement systems, additional hardware must be installed on the mobility device to provide attachment points on the cargo itself. “Passive” securement systems, such as docking-type tie-down arrangements, are actuated when the mobility device rolls into the proper position on the platform. These passive systems require special hardware adapted to the particular mobility device or cargo.
Apparatus, systems, methods and techniques that provide improved passive protection for occupants in a motor vehicle passenger area from shifting cargo in the motor vehicle's storage area, without requiring adaptation hardware, would represent a significant advancement in the art.
Embodiments of the present invention include apparatus adapted to assist in loading and unloading cargo (for example, mobility devices and the like in some cases), and to provide a storage environment in which the cargo is less likely to migrate from a storage area (for example, the cargo area of a minivan or SUV) into a passenger seating area such as the first or second row of seats in a motor vehicle. In some embodiments, a barrier composed of a barricade that is mounted to a vehicle lift, for example by being mounted to a generally vertical post, mast or the like, being mounted to a lift platform, or in any other suitable fashion that allows the lift to operate normally, while the barricade obstructs all or a substantial portion of the passage between the motor vehicle storage/cargo area and the passenger area. Where the barrier is mounted to a vertical post or the like on a vehicle lift, cut-out bracketing can be used to mate with the outer cross-sectional shape of the post, thus inhibiting pivoting of the barrier about the post. Such embodiments provide a simple, relatively inexpensive apparatus for better protecting passengers, property, etc. in the passenger compartment or area and can be retrofitted easily into many motor vehicles. Embodiments of the present invention can be deployed in motor vehicles with rear and/or side access-ways where vehicle lifts typically are provided and do not require special tie-downs or other cargo securing means, making such embodiments especially useful in vehicles that might serve a number of different passengers and/or types of cargo, mobility devices, etc. (for example, taxis, limousines and the like).
The present invention will be readily understood by the following detailed description in conjunction with the accompanying drawings, wherein like reference numerals designate like structural elements, and in which:
The following detailed description of the invention will refer to one or more embodiments of the invention, but is not limited to such embodiments. Rather, the detailed description is intended only to be illustrative. Those skilled in the art will readily appreciate that the detailed description given herein with respect to the Figures is provided for explanatory purposes and that the invention extends beyond these limited embodiments.
Certain terms are used throughout the description and claims to refer to particular components. As one skilled in the art will appreciate, like components may be referred to using different names, but this disclosure does not intend to distinguish between components that differ in name but not function. In the following discussion and in the claims, the terms “including” and “comprising” are used in an open-ended fashion, and thus should be interpreted to mean “including, but not limited to . . . ” Phrases such as “coupled to” and “connected to” and the like are used herein to describe a connection between two devices, elements and/or components and are intended (unless otherwise restricted specifically) to mean physically and/or electrically either coupled directly together, or coupled indirectly together, for example via one or more intervening elements, components or connections, where appropriate.
One or more embodiments of the present invention include a cargo barrier that is configured to be or is affixed to a vehicle platform lift or the like in the cargo area of a motor vehicle. The vehicle lift has a generally laterally-centered vertical post (that is, an upright post centered in a “side-to-side” sense inside the motor vehicle) to which a barricade is secured in some embodiments. In other embodiments the barricade is secured to another component of the lift, for example the lift platform. The barricade may be attached in a manner that not only physically blocks cargo from moving out of the cargo area and into the passenger area, but also is fixed to the vehicle lift in a manner that resists twisting from torque forces applied to the barricade during use. The vehicle lift barrier is especially useful in motor vehicles like minivans, sport utility vehicles (SUVs), and other settings where there is little or no structure between occupants in the passenger area of the motor vehicle and cargo stored in the cargo area of the motor vehicle. Various embodiments of the vehicle lift barrier are appropriate for use in vehicles having rear entry doors/hatches and side entry doors/hatches.
Many motor vehicles currently come equipped with or are retrofitted to include one or more lifts or hoists that include a platform that can be used to assist in lifting cargo into and out of the motor vehicle. Typically these lifts are mounted in vans, minivans, hatchback motor vehicles and the like due to the layout and dimensions of the vehicles' cargo storage areas, as well as their larger access-ways, such as rear hatches, side entry doors, and the like. Such motor vehicles typically have a passage provided between the cargo area and the passenger area, for example space above the backs of one of the rows of seating in the motor vehicle, or space above folded down second row seats. Any such space permitting movement of objects between the cargo area and the passenger area is referred to herein as the “passage” between such areas.
One or more embodiments of the present invention are illustrated in
Operation of lift 100 basically includes horizontal movement of a reciprocating horizontal slide mechanism 110 and vertical movement of a platform 170 controlled by a vertical linkage mechanism 120 (further details regarding operation of such a lift can be found in the 2001/0026756 document). In other lift configurations, the reciprocating horizontal slide mechanism is coupled with a telescoping vertical lift platform, as seen in the 2005/0105995 document and in U.S. Pat. No. 6,726,435 (which is incorporated herein by reference for all purposes). A variety of other lift configurations usable in and with embodiments of the present invention are well known to those skilled in the art.
When a vehicle lift (mounted adjacent either a rear or side entryway) is in its fully deployed position, as shown in
In
In the example of
In earlier lift devices and systems, once a scooter or other cargo 180 was loaded on platform 170 inside the cargo area of the motor vehicle 140, post 160 typically was the only structure (if any) interposed between the cargo in the cargo area and someone or something in the passenger area. Cargo might be tied down and/or otherwise secured to platform 170 and/or some other structure. However, restraints, tie-downs, etc. can fail or not be used at all, thus allowing the cargo to move about freely in the motor vehicle interior, especially when the motor vehicle decelerates quickly or turns suddenly. Where the cargo area is openly connected to a passenger area or the like, freely moving cargo (for example, a scooter or power chair) represents a potentially serious hazard to motor vehicle occupants. The center post 160 often is not tall enough or wide enough to prevent cargo from migrating from the cargo area to the passenger area.
One or more embodiments of a vehicle lift barrier 200 are illustrated in Figure and other Figures. Barrier 200 is mounted to the motor vehicle lift 100 to interpose and maintain barrier 200 between the passenger area of the motor vehicle 140 and any cargo on the lift platform 170 or otherwise stowed in the cargo area of the motor vehicle 140. In the embodiment shown in
In some embodiments the barrier 200 uses one or more brackets 230 to both secure the barrier 200 to post 160 of lift 100 and to reinforce the barrier 200 against rotation when a force is applied to the barrier 200 (for example, a torque applied when cargo pushes against an off-center component of the barrier 200). As seen in
As seen in
The vehicle lift barrier also can be attached directly to the lift platform of a given lift. In
When bracket 330 engages platform 370, the barricade 305 is held in place not only by the securing means 331 and/or 332, but also is held against undesirable rotation or torque by the mating of bracket 330 and platform 370. Bracket 330 and cut-outs 233 can each (or collectively) be referred to as “bracing means” in connection with embodiments of the present invention, being structures that help brace the barricade against undesirable rotation due to torque forces applied to the barricade during use.
As can be seen in
In all platform-mounted barrier embodiments, the platform's rigid structure can be used with removable or permanent securing brackets or other securing means to brace the barrier against rotation, again protecting occupants in the passenger area more effectively than if no barrier were present. Moreover, these configurations, like the above-described configurations, also provide this more effective protection without having to modify the cargo's structure (for example, adding a post or other connector onto a scooter or the like) and/or the platform's structure (again, for example, by adding a post or other connector). These configurations thus provide effective protection for all scooters, power chairs, general cargo, etc. that might by transported as cargo in the motor vehicle. This is especially helpful in motor vehicles that are used to transport a variety of personal mobility devices—for example, taxicabs, limousines and other vehicles might encounter a variety of scooters, power chairs, etc. and embodiments of the present invention permit safer transportation of such devices without requiring individualized lift equipment for each such device.
When a scooter, power chair or other cargo is on platform 170, one or more belts 185 can be used to help secure the cargo to the platform 170. Each belt 185 uses a hook 187 to secure the free end of a belt 185 to an appropriate anchoring point, for example on a mobility device, on the barrier, and/or at any other appropriate location. In the embodiment of the vehicle lift barrier 200 shown in
In motor vehicles using embodiments of the vehicle lift barrier, occupants are better protected against cargo movement toward and/or into the passenger area or compartment, even if cargo-securing belts are not available or used. The vehicle lift barrier provides a simple, inexpensive and effective barrier (whether as original equipment or as a retrofitted component) between cargo in a motor vehicle cargo area and occupants in the passenger compartment.
The many features and advantages of the present invention are apparent from the written description, and thus, the appended claims are intended to cover all such features and advantages of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, the present invention is not limited to the exact construction and operation as illustrated and described. Therefore, the described embodiments should be taken as illustrative and not restrictive, and the invention should not be limited to the details given herein but should be defined by the following claims and their full scope of equivalents, whether foreseeable or unforeseeable now or in the future.
This application claims the benefit of priority under 35 U.S.C. §119(e) and any other United States or other law of the following: U.S. Ser. No. 61/090,309 filed 20 Aug. 2008, entitled VEHICLE LIFT BARRIER, the entire disclosure of which is incorporated herein by reference in its entirety for all purposes.
