The present invention is generally related to a towing apparatus and, more particularly, to an adapter for an under bed hitch mounting system.
Many vehicles are designed to transport freight, goods, merchandise, personal property, and other such cargo. An operator often utilizes a hitch assembly to connect a towed vehicle to a towing vehicle, e.g., connecting a trailer to a pick-up truck, to increase the capacity to transport cargo. Many types of coupling devices have been developed for providing this connection between towing and towed vehicles.
It is well known to utilize a hitch to connect a towed vehicle to a towing vehicle. There are many different types of hitches that may be attached to the towing vehicle in a variety of ways, depending on the type of hitch used. For example, some fifth wheel hitches mount to the frame underneath the bed of the pickup truck while other fifth wheel hitches mount to an above bed mounting system.
Traditional fifth wheel hitches include a head assembly for receiving a king pin on a towed vehicle, a base having a plurality of legs, and one or more mounting rails. In some systems, the legs of the fifth wheel hitch are designed to be secured to mounting rails that are attached above the bed or on the bed of the towing vehicle. In other systems, the mounting rails may be fixed to the frame of a vehicle underneath the bed. For example, the mounting rails may be connected between two portions of a pickup truck frame underneath the truck bed. The mounting rails may include a plurality of apertures for receiving the legs of the fifth wheel hitch. Corresponding openings may be cut in the truck bed and aligned with the apertures in the mounting rails. The legs of the fifth wheel hitch may be connected to apertures in the mounting rails through the openings in the truck bed, thereby securing the fifth wheel hitch to the frame of the vehicle.
This configuration, however, may limit the available fifth wheel hitches that may be attached to a specific vehicle. There are a wide variety of fifth wheel hitches on the market, many of which have very different mounting configurations, including those that may only be capable of being secured above the load bed of the vehicle. Moreover, the under bed mounting systems have fixed mounting points, which may limit the available adjustability of the system. Accordingly, a particular configuration of an under bed mounting system may fit only a limited amount of configurations of fifth wheel hitches. This may limit the variety of fifth wheel hitches that may attach to a particular under bed hitch mounting system. There is a need, therefore, for an apparatus to overcome these limitations and to provide a mounting system to which accessories such as fifth wheel hitches of different varieties may attach.
An adapter for mounting an accessory to a fixed feature positioned below a load bed of a vehicle is disclosed. The adapter may include a mounting member, an aperture positioned on the mounting member, and a locking member capable of being inserted through the aperture, where the locking member is capable of selectively engaging the fixed feature. The adapter may also include at least one rail attached to the mounting member, and an accessory securing member positioned on the rail, the accessory securing member capable of selectively engaging an accessory.
An adapter for mounting an accessory to a fixed feature attached to a frame of a vehicle, where the fixed feature may include at least one receiving member is disclosed. The adapter may include a mounting member and a locking member selectively positionable on the mounting member, where the locking member is capable of selectively engaging the receiving member of the fixed feature. The adapter may also include at least one rail attached to the mounting member, and an accessory securing member positioned on the rails, the accessory securing member capable of selectively engaging an accessory.
An adapter for mounting an accessory to an under bed hitch mounting system attached to a frame of a vehicle where the under bed hitch mounting system may include at least one receiving member. The adapter may include a mounting member, and at least one locking member engageable with the mounting member and capable of selectively engaging the receiving member. The adapter may also include at least one rail attached to the mounting member, and a plurality of accessory securing members positioned on the rails at predetermined locations, any one of the plurality of accessory securing members capable of selectively engaging an accessory at the predetermined locations along the rail.
Operation of the invention may be better understood by reference to the following detailed description taken in connection with the following illustrations, wherein:
Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. It is to be understood that other embodiments may be utilized and structural and functional changes may be made without departing from the respective scope of the invention. Moreover, features of the various embodiments may be combined or altered without departing from the scope of the invention. As such, the following description is presented by way of illustration only and should not limit in any way the various alternatives and modifications that may be made to the illustrated embodiments and still be within the spirit and scope of the invention.
In some embodiments, the under bed mounting system 20 may include at least one rail or transverse member 22 having a top surface 24 and may include at least one mid rail or adapter plate 25. By way of a non-limiting example as shown in
Each rail 22 of the under bed hitch mounting system 20 may include one or more sockets 27. The sockets 27 may be of any appropriate shape or size, such as a generally ovular, circular or rectangular shape and may accept some form of receiving member 28. In these embodiments, apertures may be drilled or cut in the load bed of the applicable vehicle where such apertures generally correspond to the locations of the sockets 27 in the rails 22.
In an embodiment shown, the sockets 27 may be configured to receive a receiving member 28 that may comprise a puck mounting system, such as that disclosed in U.S. Patent Application Publication No. 20100109285, entitled “UNDERBED HITCH MOUNTING SYSTEM,” and that disclosed in U.S. Pat. No. 7,121,573, entitled “VEHICLE ACCESSORY MOUNTING SYSTEM,” the disclosures of which are incorporated by reference herein. Utilizing a puck mounting system may provide uninhibited use of the truck bed when the fifth hitch and adapter 10 are dismounted from the under bed hitch mounting system 20.
While the exemplary embodiments of the under bed hitch mounting system 20 are shown and described herein, the present teachings are not limited to exemplary under bed hitch mounting system 20. Any appropriate hitch mounting system may be utilized. By way of a non-limiting example, the under bed hitch mounting system shown and described in U.S. Patent Application Publication No. 20100109285, entitled “UNDERBED HITCH MOUNTING SYSTEM,” U.S. Pat. No. 7,121,573, entitled “VEHICLE ACCESSORY MOUNTING SYSTEM,” and U.S. application Ser. No. PCT/US11/63922, entitled “UNDER BED HITHC MOUNTING SYSTEM,” the disclosures of which are incorporated by reference herein.
Specific versions of fifth wheel hitches may attach directly to the under bed hitch mounting system 20; provided that the configuration of the fifth wheel hitch generally matches that of the under bed hitch mounting system 20. If, however, the fifth wheel hitch and the under bed hitch mounting system 20 are not configured to match, the fifth wheel hitch may not capable of being attached directly. The adapter 10, therefore, may be used to attach the fifth wheel hitch or any other appropriate accessory to the under bed hitch mounting system 20. Moreover, if there is a need or desire to attach the fifth wheel hitch 26 above the load bed 12 of the towing vehicle 14 instead of under the load bed 12, the adapter 10 may be used.
In some embodiments, the adapter 10 may include at least one mounting member 30 having end portions 32, 34. The mounting member 30 may be made of any appropriately rigid material such as by way of a non-limiting example, steel. Further, in some embodiments, the mounting member 30 may be a plate that has a generally flat bottom portion 35 and a top portion 36 that may generally bend over the bottom portion 35. It should be understood, however, that the mounting member 30 may be of any appropriate shape, such as by way of non-limiting examples, generally square, circular, trapezoidal, elliptical, or a combination thereof. In other embodiments, the mounting member 30 may be a generally tubular member.
The longitudinal members 30 may include a plurality of apertures 38 positioned at appropriate positions along the bottom portion 35 thereof. In some embodiments, each mounting member 30 may include four such apertures 38, positioned as shown in
The apertures 38 may be positioned such that the apertures 38 may generally align with an appropriate under bed hitch mounting system, such as by way of a non-limiting example, the under bed hitch mounting system 20. By way of a non-limiting example, the apertures 38 may be positioned along the mounting member 30 so that they may generally align with the sockets 27 of the rails 22. Therefore, the adapter 10 may be able to be secured to the under bed hitch mounting system 20 even if the sockets 27 of the applicable under bed hitch mounting system 20 are in different positions. In these embodiments, therefore, at least two of the apertures 38 may generally align with the sockets 27.
Further, the mounting member 30 may include access points 39. In some embodiments, the access points 39 may be generally formed by the formation of the top portion 36 and bottom portion 35. By way of a non-limiting example, the top portion 36 may be generally folded, bent or the like relative to the bottom portion 35. During this process, the access points 39 may be generally formed in any appropriate manner. The access points 39 may permit an operator to generally access the apertures 38 on the mounting member 30. This access may assist in installing the adapter 10 to the under bed hitch mounting system 20 and the appropriate vehicle. While the access points 39 in the present embodiments are shown as being formed by folding of the top portion 36, the present teachings are not limited to such. By way of a non-limiting example, the access points 39 may be formed by including an opening in the generally rectangular tubular mounting member 30, by including slots in the mounting member 30 or any other appropriate process.
In some embodiments, the adapter 10 may include at least one rail 40—the rail may include a first end 42 and a second end 44. In the exemplary embodiments shown, the adapter 10 may include a pair of rails. In these embodiments, the ends 32, 34 of the mounting members 30 may generally attach to the ends 42, 44 of the rails 40. The mounting members 30 and the rails 40 may be attached in any appropriate manner, such as by way of a non-limiting example by welding, adhesives, fasteners or the like. In some embodiments, the mounting members 30 and the rails 40 may be welded together.
The rails 40 may include any appropriate number of accessory securing members 45. In some embodiments, the accessory securing members 45 may include slot 46 and corresponding aperture 48. In these embodiments, the rails 40 may include any appropriate number of slots 46 and apertures 48, e.g., one, two, three, four, etc., wherein the apertures 48 may generally correspond to the position of slots 46. In some embodiments, the rails 40 may include a plurality of slots 46 and a plurality of apertures 48; the apertures 48 may generally correspond to the position and number of slots 46. By way of a non-limiting example, each end 42, 44 of the rails 40 may include a pair of slots 46 and a pair of apertures 48; wherein the slots 46 may be generally positioned in conjunction with the apertures 48 along the rails 40. Although each end 42, 44 of the rails 40 are shown to include a pair of slots 46 and apertures 48, the present teachings are not limited to this. Any appropriate number of slots 46 and apertures 48 may be used.
The slots 46 may be sized and positioned along the rails 40 such that a leg 51 of the fifth wheel hitch 26 may be appropriately secured thereto. In some embodiments, the slots 46 may be sized and positioned such that the leg 51 of the fifth wheel hitch 26 may be inserted into the appropriate slot 46. The number and position of the slots 46 and apertures 48 may generally correspond to the position of the legs of varieties of fifth wheel hitches that may be capable of attaching to the adapter 10. In some embodiments, the rails 40 may include more than the two pairs of slots 46 and apertures 48 to accommodate fifth wheel hitches having legs spaced apart different amounts.
It should be understood, however, that although the accessory securing members 45 are shown as slots 46 and corresponding apertures 48, the present teachings are not limited to such. The accessory securing members 45 may include any appropriate mechanism that may attach the fifth wheel hitch 26 or other accessory to the adapter 10.
In operation, the adapter 10 may help facilitate the mounting of an accessory to a fixed feature on a vehicle. By way of a non-limiting example, the adapter 10 may facilitate an accessory such as the fifth wheel hitch 26 including, without limitation most any after-market fifth wheel hitch, to be attached to most any kind of fixed under bed mounting system 20. In some embodiments the operator may attach and remove the fifth wheel hitch 26 with generally reduced effort. The operator may attach the adapter 10 to the under bed hitch mounting system 20 of the vehicle and then attach the fifth wheel hitch 26 to adapter 10 in any appropriate manner. To remove the fifth wheel hitch 26 from the towing vehicle 14, the operator may need only remove the adapter 10 from the under bed hitch system 20 while leaving the fifth wheel hitch 26 attached to the adapter 10.
More specifically, in some of these embodiments, the adapter 10 may attach to the under bed hitch mounting system 20 in any appropriate manner. By way of a non-limiting example, the adapter 10 may be placed onto the load bed 12 of the towing vehicle 14. The apertures 38 of the mounting member 30 may generally align with the sockets 27 in the rails 22 of the under bed hitch mount 20. A locking member 52 may then be inserted through the aperture 38 in the mounting member 30 and into the sockets 27. This may attach the adapter 10 to the under bed hitch mounting system 20. This may be repeated for each of the apertures 38 that correspond with the applicable socket 27.
By way of a non-limiting example, the locking member 52 of some embodiments may comprise a quarter turn T-bolt system, such as that shown in
In some embodiments, the receiving members 28 may include a projecting rim or upper wall 60 and a locking cavity 66. The locking cavity 66 may have a generally acircular cross sectional shape. The locking member 52 may include at least one locking lug 71 and an accessory mounting shank 74. As shown, the locking member 52 may include two opposed locking lugs 71. The locking member 52 may be capable of entering into and seating in the cavity 66. Once fully seated, the locking member 52 may be rotated approximately 90 degrees with respect to the receiving member 28 other so that the locking lugs 71 may engage the receiving member 28 thereby securing the locking member 52 in the receiving member 28.
The locking member 52 may be secured to the mounting member 30 by means of the mounting shank 74 and a matingly engaging nut 78. More specifically, the accessory mounting shank 74 may be inserted through at least one of the apertures 38 in the mounting member 30, or more specifically in the bottom portion 35 thereof and the nut 78 may matingly engage the mounting shank 74. A control handle 80 may then be connected to the locking member 52. The control handle 80 may be positioned so that the accessory mounting shank 74 may extend up through the mounting member 30 may be received in an aperture 82 in the control handle 80. The aperture 82 may be generally acircular and may engage a cooperating acircular shoulder on the accessory mounting shank 74. The nut 78 may then be tightened down on the accessory mounting shank 74 so as to secure the control handle 80 to the locking member 52 and the locking member 52 to the mounting member 30.
When it is desired to selectively attach the adapter 10 to the under bed hitch mounting system, each locking member 52 may be aligned by operation of its respective control handle 80 so that the locking member 52 including the locking lugs 71 may be appropriately aligned with the associated receiving member 28. This may allow for the clearance necessary to generally allow each locking member 52 to drop into and be fully seated in the locking cavity 66 of the associated receiving member 28. Once each locking member 52 is fully seated, the control handle 80 may be rotated through an arc of approximately 90 degrees. Simultaneously, the locking member 52 may be rotated so that the locking lugs 71 may engage the locking cavity 66.
This engagement between the lugs 71 and the locking cavity 66 may serve to secure the locking member 52 in the receiving members 28 and, therefore, the adapter 10 to the under bed hitch mounting system 20. The control handles 80 may be secured in a locking position. The present teachings, however, are not limited to the above locking member. Any appropriate system may be used with the adapter 10, not just the locking member 52 shown and described above.
In some embodiments, once the adapter 10 may be attached to the under bed hitch mounting system 20 of the vehicle, the fifth wheel hitch 26 may then be attached to the adapter 10. In these embodiments, the legs 51 of the fifth wheel hitch 26 may be inserted into the slots 46, a fastener (not shown) may then be inserted into apertures 48, which may secure the legs 51 of the fifth wheel 26 hitch to the rails 40. Alternatively, many aftermarket fifth wheel hitches use pins and clips to attach to the towing vehicle 14. In these embodiments, the legs 51 of the fifth wheel hitch 26 may be inserted into the corresponding slot 46. A pin 88 may then be inserted through the aperture 48. The clip (not shown) may be inserted into the pin to secure the fifth wheel hitch 26 to the adapter 10 and in turn to the under bed hitch mounting system 20. In these embodiments, the fifth which hitch 26 may be attached above the load bed 12 of the towing vehicle 14. In yet other embodiments, the legs 51 of the fifth wheel hitch 26 may be welded directly to the rail 40 or otherwise attached directly thereto.
To remove the fifth wheel hitch 26, the operator may remove the adapter 10 from the vehicle, or more specifically, from the under bed hitch mounting system 20. This may permit the load bed 12 of the towing vehicle 14 to be fully accessible and useable. In particular, in some embodiments, the operator may rotate the handle one-quarter turn and remove the locking lugs 71, i.e., T-bolts, from the aperture 38 and the corresponding socket 27. The operator may repeat this step for each locking member 52 present. Once all of the fasteners 52 have been loosened, the combination of the adapter 10 and the accessory, e.g., the fifth wheel hitch 26, may be removed from the vehicle. The fifth wheel hitch 26 need not be removed from the adapter 10, but may be if desired.
In some embodiments, the adapter 10 may provide a clearance for the load bed 12 of the towing vehicle 14. In particular, the adapter 10 being attached to the under bed hitch mounting system 20, may provide a clearance such as one-quarter to one-half of an inch. This clearance may generally prevent the adapter 10 and the fifth wheel hitch 26 from contacting the load bed 12 of the towing vehicle 14. Moreover, there may be enough clearance to allow a bed liner to be placed between the adapter 10 and the under bed hitch mounting system 20.
