    [0001] [001] This document generally refers to elevator floors and, more particularly, elevator floors positioned in utility vehicle storage areas. BACKGROUND
    [0002] [002] The entry and exit of cargo in vehicle storage areas is an old dilemma for vehicle owners. Bulky cargo is difficult to handle in the storage area and difficult to position once inside the storage area. Similarly, it can be difficult to lift the heavy load from ground level to a flap in the storage area, and it is often at least as difficult to lower it onto the floor of the storage area. An additional difficulty may be encountered when removing heavy or bulky cargo from the storage area.
    [0003] [003] In order to overcome and alleviate some of the problems in this area, the prior art reveals several mechanisms for raising and lowering a floor inside a storage area like the trunk of an automobile. An example of the prior art includes the lifting mechanism described in U.S. Patent No. 4,969,793 to Pawl. The mechanism includes an electric elevator that is adapted to be mounted on a wheel cavity that covers a portion of an automobile trunk. The elevator has connections for raising or lowering a load-bearing floor in relation to the trunk floor in a vertical direction. The load support floor can also be manually moved in a horizontal direction to remove the load from the trunk and pivot around the fixed support frame when the load support floor is positioned on the trunk floor. Pivoting the load support floor in this way provides access to the wheel cavity portion of the trunk floor positioned below the load support floor.
    [0004] [004] While prior art lift mechanisms are sufficient to provide assistance with loading and unloading cargo in an automobile storage area and providing access to the wheel cavity that includes the spare tire and specific tools, vehicle designs specifics demand even more functionality in relation to such mechanisms. With the advent of utility vehicles, such as sport utility vehicles and utility vehicles for crossing, for example, the useful area of the area available for storage has decreased in comparison with automobile storage areas. more traditional. The smaller footprint is created primarily by narrowing the storage area from the rear of the utility vehicle inwards to accommodate additional passenger space within the vehicle (for example, third seat row). In order to maintain sufficient space for cargo storage, the storage areas are necessarily deeper from the top to the bottom compared to previous storage areas.
    [0005] [005] As a result, utility vehicle storage area designs often result in the stacking of belongings and, most importantly, placing an initial layer of belongings on a floor of the storage area, which is often below the top flap. of an access area adjacent to a rear elevator door. Depending on the platform on which the utility vehicle is built, the floor of the storage area where the initial layer of belongings is placed can be significantly below the top flap, creating even greater challenges by loading heavy and / or bulky cargo and unloading of the same.
    [0006] [006] In view of the size limitations of utility vehicle storage areas, modern elevator mechanisms should be designed to maximize the useful area of the storage area by covering a maximum portion of the useful area with a supporting floor of cargo instead of a central portion of the storage area as shown in the Pawl patent. The use of substantially the entire floor of the storage area, however, results in limited access within the cargo area for service or access to a spare tire compartment and further limits the available storage area. In current utility vehicles for crossings and sports, it is therefore desirable that the load bearing floor of the lift mechanism is removable from the vehicle.
    [0007] [007] Removing the floor provides easier access to cabling for vehicle lights, power outlets and speakers, for example, which are often positioned inside or are directly adjacent to the utility vehicle storage area and often , require service access. In addition, although the tread can be pivoted to provide access to a spare tire compartment, some customers prefer to remove the load-bearing floor to access the spare tire and specific tools rather than endeavoring to remove the spare tire from under the tire. pivoted floor and over the raised access flap of the storage area. This applies particularly to utility vehicles with a lowered storage area floor. Still, other customers simply want to remove the load-bearing floor to gain additional cargo storage volume when required.
    [0008] [008] This document refers to an elevator assembly for a utility vehicle storage area that provides a floor with the ability to lift and lower the load within the storage area. In addition, the elevator assembly uses rollers to create a pivot point around which the floor pivots to allow access to a spare wheel and tire cavity. Using rollers in this way allows the floor to be removed when desired simply by raising the floor from the storage area. This advantageously allows the floor to be separated from the elevator assembly and completely removed from the utility vehicle when desired. This removal provides easier access to the spare tire compartment within the storage area and allows easier access to underlying systems and cabling within the vehicle for service. SUMMARY
    [0009] [009] In accordance with the purposes and benefits described in this document, an elevator assembly for a utility vehicle storage area is provided. The elevator assembly can be broadly described as a comparison with a floor supported by a scissor mechanism and an actuator to lift the scissor mechanism and the floor from a neutral position to an elevated position. The guide members can be attached to the scissor mechanism within which a plurality of rollers, attached to the floor, move. A holder that protrudes into one of the guide members to resist the rotation of at least one of the plurality of rollers can be provided, which creates a pivot point around which the floor rotates to a pivoted position.
    [0010] [010] In other possible modalities, the floor can be rotated to the pivoted position from the neutral position, from the elevated position or from any position between the neutral and elevated positions.
    [0011] [011] In a possible embodiment, the scissor mechanism includes at least one lateral crossed arm. In another embodiment, the plurality of rollers may be attached to a bottom side of the floor which includes a first pair of rollers attached adjacent to a rear edge of the floor and a second pair of rollers attached separate from said first pair of rollers between an edge front and rear edge of said floor.
    [0012] [012] In yet another possible modality, the guide members include a cutout through which the second pair of rollers passes when the floor is rotated to the pivoted position. In addition, the first pair of rollers also crosses the cutouts when removing the floor from the elevator assembly.
    [0013] [013] In another possible embodiment, the first and second pairs of rollers can be positioned within the guide members and at least one of the rollers in the first pair of rollers is in contact with the holder and the second pair of rollers is adjacent to the cutouts, in the neutral position and in the elevated position. Similarly, the first and second pairs of rollers can be positioned within the guide members and at least one of the plurality of rollers is not in contact with the holder in an extended position.
    [0014] [014] In another possible embodiment, the scissor mechanism can include a pair of first and second pivotally connected supports and a base, where the first supports are attached adjacent to a first end to the base and attached adjacent to a second end to the guide member, and the second supports have a member attached adjacent to a first end for movement along the base and attached adjacent to a second end to the guide member.
    [0015] [015] In another possible embodiment, the base may include a pair of elongated channels, and the fixed member adjacent to the first end of the second supports is a roller that moves within the elongated channels.
    [0016] [016] In yet another possible mode, at least one of the first and second pivotally connected supports may include a channel within which at least a portion of the actuator is positioned in the neutral position.
    [0017] [017] In another possible mode, the floor can rotate to a pivoted position from the neutral position, from the elevated position or from any position between the neutral and elevated positions. In addition, the scissor mechanism may include at least one lateral crossed arm.
    [0018] [018] In a possible embodiment, the plurality of rollers can be fixed to a bottom side of the floor which includes a first pair of rollers fixed adjacent to a rear edge of the floor and a second pair of rollers fixed between a front edge and the edge rear of the floor. Guide members may include a cutout through which the second pair of rollers passes when the floor is rotated to the pivoted position and the first and second pair of rollers pass through the cutouts when removing the floor from the elevator assembly. The storage area elevator assembly can be included in a utility vehicle.
    [0019] [019] In another possible embodiment, a lift assembly for a utility vehicle storage area includes a removable floor, a pair of first and second pivotally connected supports that support the removable floor and a base. Each of the first supports is attached adjacent a first end to the base and attached adjacent a second end to a guide member. Each of the second supports has a roller attached adjacent to a first end for movement along the base and is attached adjacent to a second end to the guide member. The assembly additionally includes an actuator for raising and lowering the pair of first and second pivotally connected supports and the removable floor, a plurality of rollers attached to the removable floor for movement within the guide members and a stopper projecting into the interior of a of the guide members to resist the rotation of at least one of the plurality of rollers and to create a pivot point around which the floor rotates to a pivoted position.
    [0020] [020] In an additional aspect, a method of removing a floor from an elevator assembly from a utility vehicle storage area is provided. The method can be widely described as comprising the steps of: (a) operating a scissor mechanism that supports the floor to move the floor to a removal position; (b) pivot the floor from the removal position to a pivoted position; (c) applying sufficient force to the floor to release a fixed roller adjacent to a rear edge of the floor and positioned within a guide member attached to a keeper's scissor mechanism; (d) maintain force until the roller is adjacent to a cutout in the guide member; and (e) raise a rear edge of the floor so that the fixed roller passes through the cutout in the guide member.
    [0021] [021] In a possible embodiment, the supply step includes raising a front edge of the floor so that a second roller fixed between a front edge and the rear edge of the floor crosses the cutout in the guide member before the step of applying a force.
    [0022] [022] In another possible embodiment, the method may include the step of additional shoring of the scissor mechanism with at least one lateral support.
    [0023] [023] In the following description, various preferred modes of elevator assembly for a utility vehicle storage area and the related method are shown and described. As it should be done, the assemblies and the method are capable of other different modalities and their various details are capable of modification in several obvious aspects, all without deviating from the systems and method as presented in the following claims. Consequently, drawings and descriptions should be considered as illustrative in nature and not as restrictive. BRIEF DESCRIPTION OF THE DRAWING FIGURES

    [0034] [034] Reference will now be made in detail to the present preferred elevator assembly modalities, examples of which are illustrated in the figures in the attached drawing. DETAILED DESCRIPTION
    [0035] [035] Reference is now made to Figure 1, which broadly illustrates an embodiment of an elevator assembly 10 that has a removable floor 12. The floor 12 is supported by a scissor mechanism 14 which is raised from a neutral position ( or lowered) to an elevated position by an actuator 16. The scissor mechanisms use folding brackets connected in a cross pattern or “X” pattern that are typically attached to a base. Extension is achieved by applying pressure to an external pair of supports located at one end of the mechanism, thereby elongating the cross pattern. The applied pressure can be achieved through hydraulic, pneumatic, mechanical or simply muscular means. Obviously, supports and bases can be made of metals, plastics and other materials and can take many shapes to accommodate particular design requirements or resources.
    [0036] [036] As shown in Figure 2, the scissor mechanism 14 includes two pairs of first and second pivotally connected supports 20, 22 and a base 18. The first and second pivotally connected supports 20, 22 and the base 18 are manufactured from of a light extruded aluminum in the described mode. The first supports 20 are attached adjacent a first end 24 to the base 18. More specifically, the first supports 20 are attached to a rear area 26 of the base 18. Similarly, the second supports 22 are pivotally connected to the first supports 20 in the pivot point 28 creating an X-type configuration. A roller 30 is attached adjacent a first end 32 of each of the second supports 22. The rollers 30 are confined within the base 18 for movement therein as will be described in more detail below . In another embodiment, a member (not shown) can replace the roller. The limb can be spherical, semi-spherical, piano-shaped or generally any shape as long as the limb has the ability to move along the base. A second end 34 of the second supports 22 is pivotally attached to guide members 36 to allow the scissor mechanism 14 to be raised and lowered.
    [0037] [037] One or more lateral crossed arms 38 can also be used. In the described embodiment, lateral tubular crossed arms 38 extend between pairs of first and second pivotally connected supports. A first side arm 40 is attached adjacent the first ends 32 of the second supports 22 next to the rollers 30. A second side arm 42 is attached to the second supports 22 in a position between the pivot point 28 formed by the first and second supports and the second end of the second support 34. As will be described below, the second side arm 42 is attached next to an attachment point of the actuator 16. A third side arm 44 is attached adjacent to the second ends 46 of the first supports 20 next to the guide members 36 and floor 12 (not shown in this figure). Obviously, fewer or more arms can be used depending on numerous factors, for example, the general dimensions of the elevator mechanism or the expected loads on the floor.
    [0038] [038] In the described embodiment, base 18 includes a pair of guide members 48, as shown in Figure 1, which can be attached to a frame of the utility vehicle. In the described embodiment, angular supports 50 are fixed to the ends of the base 18 and screwed to the vehicle. A side arm 52 extending between the guide members 48 of the base can also be used. As shown, the side arm 52 can similarly be screwed to the vehicle adjacent the base guide members 48 and can be formed to extend into the vehicle's wheel cavity to stop any displacement of the base 18 during use. Obviously, other methods for attaching the base to the vehicle and stopping the displacement can be used in accordance with the broad teachings in this document. Guide members 48 of the described base have C-shaped channels within which the scissor mechanism rollers 30 are allowed to move. The C-shaped channels 48 limit the rollers 30 to a linear direction which forces the scissor mechanism 14 to be raised and lowered.
    [0039] [039] The actuator 16 is pivotally fixed at its first end 54 to a first end of the first support 24 at the rear of the base 26. A second end 56 of the actuator 16 is similarly pivoted to the second support 22 in a position between the pivot point 28 formed by the first and second supports and the second end of the second support 34. As the actuator 16 extends, the second end 56 of the actuator forces the second support 22 upwards while the first end 54 of the actuator rotates in around its pivoting fixation to the first end of the first support 24. Raising the second support 22 necessarily raises the first support 20, thereby raising the floor 12. In the reverse way, as the actuator 16 retracts, the second the end of the actuator 56 pulls the second support 22 downwards by reversing the upward movement described above.
    [0040] [040] As shown in Figure 3, the actuator 16 can be retracted to a completely retracted position where the scissor mechanism 14 is substantially flat. This is the neutral or lowered position. In that position, the actuator 16 is positioned substantially or completely within the first support 20. The first and second supports 20, 22, in the described embodiment, are generally U-shaped channels that provide structural integrity while maintaining a light weight. As shown in Figure 1, actuator 16 is pivotally secured within the U-shaped channel of the second support 22. In this way, actuator 16 is received within the U-shaped channel of the second support 22 as the scissor mechanism 14 is lowered to the neutral position and does not affect the movement range of the scissor mechanism.
    [0041] [041] As best shown in Figure 1, a second actuator 16 is attached to the second pair of supports to provide additional stability during operation of the scissor mechanism 14. More specifically, a first end of the second actuator 60 is pivotally fixed to a second end of the first support 46 at the rear of the base 26. A second end of the second actuator 62 is similarly pivotally fixed to the second support 22 in a position between the pivot point 28 formed by the first and second supports and the second end of the second support 34. As the actuator 16 extends, the second end of the post 62 extends with the second support 22 upwards while the first end of the actuator 60 rotates around its pivoting attachment to the first end of the first support 24. As before, actuator 16 is pivotally secured within a U-shaped channel of the second support 22. Thus, as the scissor mechanism 14 is lowered to the neutral position, the post is positioned inside the U-shaped channel of the second support and does not interfere with the movement range of the scissor mechanism.
    [0042] [042] As best shown in Figure 4, a plurality of rollers 64 is attached to a lower side of the floor 12 for engagement with the guide members 36 attached to the scissor mechanism 14. In the described embodiment, four rollers 64 are attached to the side bottom of the floor. Specifically, a first pair of rollers 68 is attached adjacent a rear edge 70 of the floor 12 and a second pair of rollers 72 attached between a front edge 74 of the floor and the rear edge of the floor. The rollers 64 are generally positioned and secured within the guide members 36, or channels, within which the rollers are limited to movement along a linear direction.
    [0043] [043] The guide members 36 are attached to the scissor mechanism 14 for movement with the same and, in the described mode, include cutouts 76 positioned between the front edge 74 and the rear edge 70 of the floor. Specifically, as best shown in Figure 2, cutouts 76 are positioned adjacent to the second pair of rollers 72. This allows the second pair of rollers 72 to pass through cutouts 76 when the floor 12 is rotated to a pivoted position as shown in Figure 4.
    [0044] [044] As shown in Figure 5, a holder 78 protrudes into one of the guide members 36 that prevent the rotation of the roller 64. A holder is a device used to resist or mechanically prevent the rotation of a wheel, roller or axis. Such a device can be anything from a simple metal pin to a machine. Holder 78, in the described embodiment, is a spring holder, but, as noted, the holder can take any shape sufficient to resist or prevent the rotation of roller 64. In addition, a second holder (not shown) can be used in any way. similar way in association with a second roller 64.
    [0045] [045] As shown, the roller 64 is positioned adjacent to the stop 78 which prevents its rotation and locks the floor 12 in a neutral or completely installed position. This prevents movement of the floor 12 due to displacement of cargo, particularly when the vehicle is in transit. In this neutral position, the second pair of rollers 72 is adjacent to the cutouts 76 in the guide members 36 allowing the second pair of rollers to pass through the cutouts as the floor 12 pivots upwards. Pivoting the floor in this way can occur when the floor is in the neutral position, in the elevated position, or in any position between the neutral and elevated positions. In addition, retaining roller 64 in the neutral position so that the roller is in a position close to the rear of the guide member 36 allows the floor 12 to pivot around roller 64 to a pivot position. The formation of a pivot point 80 using a roller 64 attached to the floor allows removal of the floor when desired. Removal is performed by pivoting the floor 12 so that the second pair of rollers 72 crosses the cutouts 76 of the guide member and pull the floor in a direction outside the vehicle until the first pair of rollers 68 is adjacent to the cutouts of the guide member. guide member. Raising the floor 12 so that the first pair of rollers 68 passes through the cutouts 76 of the guide member releases the floor of the elevator assembly 10.
    [0046] [046] Installing the floor 12 is an easy reverse process in which the first pair of rollers 68 is positioned over the cutouts 76 of the guide member and allowed to enter the guide members 36. Applying a rear force to the floor 12 moves the first pair of rollers 68 along the guide members 36 until the second pair of rollers 72 is positioned adjacent to the cutouts 76 of the guide member. By allowing the second pair of rollers 72 to enter the guide members 36 and applying additional rear force, they pass the stop 78 from a front side which allows the first pair of rollers 68 to be seated on a rear side of the stop in neutral or fully installed position.
    [0047] [047] In order to move the floor 12 to the extended position shown in Figure 6, a force is applied to the floor sufficient to pass the stop 78 allowing the plurality of rollers 64 to move linearly within the guide members 36. The floor 12 can be extended to any length, in the embodiment described it is limited by the length of the guide member 36. Other arrangements can include one or more additional holders or an intermediate stop between the neutral position and a fully extended position. It is important to note that the floor can be extended from the neutral position, from the elevated position or from any position between the neutral and elevated positions.
    [0048] [048] In another embodiment, the elevator assembly 10 for a utility vehicle described above and all the variations described therein are incorporated into a utility vehicle (not shown).
    [0049] [049] In another aspect of the invention, a method of removing a floor 12 from an elevator assembly 10 from a utility vehicle storage area is illustrated in Figures 7A-7C. In the first step shown in Figure 7A, a scissor mechanism 14 that supports the floor 12 is actuated to move the floor to a removal position. The removal position can be the neutral or fully installed position, the elevated position or any position between the neutral and elevated positions. This allows the vehicle operator or service technician to adjust the height of the floor depending on the height of the user, the desired method of lifting the floor or other factors.
    [0050] [050] In the removal position, the vehicle operator or service technician pivots the floor 12 to a pivoted position. This is accomplished by raising the front edge of the floor 74 allowing the second pair of rollers 72 to pass through the cutouts 76 of the guide member as shown by the action arrow A in Figure 7B. Since the floor 12 is in the pivoted position and the front edge 74 is raised releasing the second pair of rollers 72, a force is applied to the floor sufficient to release the roller 64 from the holder 78.
    [0051] [051] As described above, this allows the floor 12 to be pulled in one direction out of the vehicle as shown by the action arrow B in Figure 7B. According to the method, the pulling force is maintained until the first pair of rollers 68 is adjacent to the cutouts 76 of the guide member. A rear edge of the floor 70 can then be raised as shown by the action arrow C in Figure 7C so that the first pair of rollers 68 passes through the cutouts 76 of the guide member, thereby releasing the floor 12 of the elevator assembly 10. The floor 12 can then be set aside during vehicle maintenance, accessing the spare tire and specific tools or for an entire journey in which the entire storage area is desired for loading.
    [0052] [052] In another aspect of the method of removing the floor 12 from the elevator assembly 10 of the utility vehicle storage area, the scissor mechanism 14 can be propped up using at least one side support 38 as shown in Figure 2 In the embodiment described above, three side supports 40, 42, 44 are used to anchor the scissor mechanism 14.
    [0053] [053] Reinstalling the floor 12 is an easy reverse process in which the floor is positioned so that the first pair of rollers 68 is on the cutouts 76 of the guide member. The floor 12 is lowered allowing the first pair of rollers 68 to enter the guide members 36. Applying a rear force to the floor 12 moves the first pair of rollers 68 along and within the guide members 36 until the second pair of rods 72 is positioned adjacent to the cutouts 76 of the guide member in a pivoted position. By allowing the second pair of rollers 72 to enter the guide members 36 and applying additional rear force, they overtake the stop 78 from a front side of it which allows the first pair of rollers 68 to be seated on a back side holder in the removed position. As noted above, the removal position can be the neutral or fully installed position, the elevated position or any position between the neutral and elevated positions depending on the position of the scissor mechanism 14. Again, this allows the vehicle operator or technician to service adjust the height at which the floor 12 will be reinstalled depending on the height of the user, the desired floor elevation method or other factors.
    [0054] [054] In short, there are several benefits from providing an elevator assembly 10 for a utility vehicle that can be removed from the assembly and vehicle if desired. The particular design allows easy removal of the floor 12 without the need for tools or disassembly of the assembly. This advantageously allows the entire storage area to be used, easier access to the spare tire and specific tools and easier access to the underlying systems and cabling during vehicle maintenance.
    [0055] [055] The above was presented for the purposes of illustration and description. It is not intended to be comprehensive or to limit the modalities to the precise form shown. The obvious variations and modifications are possible in light of the above teachings. All such modifications and variations are within the scope of the appended claims, when interpreted according to the scope to which they are entitled in a correct, legal and equitable manner.
