The tow adapter 100 includes a bracket 104, loop 106, and hook 108. The loop 106 includes a first end 110 and a second end 112 each secured to the bracket 104. The hook 108 is secured to the bracket 104 and positioned centrally between the ends 110, 112 of the loop 106. As further illustrated in this view, the hook 108 extends upward away from the bracket 104 and is positioned to face away from the loop 106.
The tow adapter 100 may be attached to a vehicle undercarriage or the like. The tow adapter 100 may be attached directly to a towing vehicle 126 or device to be towed 128, such as to the frame, body, undercarriage, or other structural portion. Accordingly, the tow adapter 100 may be attached to the rear of a towing vehicle such as a tractor, truck, car, off-road vehicle, boat, or any other type of vehicle for towing a device to be towed such as a trailer or the like.
The tow adapter 100 illustrated in FIG. 1 is connected to the vehicle undercarriage by means of a bracket 104. The bracket is shown in further detail in FIG. 2. As illustrated in FIG. 2, the bracket 104 includes a base portion 114 attachable to a vehicle undercarriage and at least one opening 118 for securing the bracket 104 to the undercarriage. The bracket 104 may also include a number of indentations 116 for reducing stress on the bracket 104 during manufacturing and use.
The base portion 114 of the bracket 104 may include one or more openings 118 for receiving a corresponding number of fasteners 120 (FIG. 5A) for attaching the bracket 104 to the vehicle's undercarriage. Alternatively, the bracket 104 may be welded to the undercarriage or may include integrally formed fasteners for rapid assembly. In the embodiment illustrated in FIG. 2, the opening 118 is a slotted opening having an enlarged circular portion 119 connected to a narrow slotted portion 121 for rapid attachment of the tow adapter to the vehicle. The enlarged circular portion 119 of the opening 118 is sized to receive the head of a fastener, such as a cap screw or a bolt, and the narrow slotted portion 121 is sized to receive the shaft of the fastener. In this arrangement, a bolt for connecting the bracket 104 to the vehicle may be inserted through the enlarged circular portion 119 of the opening 118 and the bracket 104 and slid into place so that the shaft of the fastener is within the narrow slotted portion 121. The fastener may then be tightened, thereby securing the bracket 104 to the vehicle through frictional engagement between the fastener and bracket 104.

The base 122 of the hook 108 according to the illustrated embodiment is welded to the base 104. However, it will also be appreciated that the base 122 may include a number of openings corresponding to openings on the base portion 114 of the bracket 104 and may be secured to the bracket 104 by fasteners. It is further contemplated that the hook 108 may be integrally formed with the bracket or attached using separate fasteners. The curved portion 124 of the hook 108 extends up and away from the base 122 and is curved towards the base 122, towards the towing vehicle and away from the loop 106 to secure a tether 109. The curved portion 124 is preferably integrally formed with the base 122 of the hook 108.
Also shown in FIG. 3B is the loop 106 having first 110 and second 112 ends secured to the bracket 104. In the illustrated embodiment the loop 106 is a continuous length of metal curved about the hook 108 to provide a loop for receiving a tether 109 for coupling a device to be towed to a towing vehicle and facilitate towing thereof.
FIG. 3B also shows the arrangement of the tether 109 relative to the loop 106 and hook 108. According to this embodiment, a loop is formed in the tether 109 and passed over the loop 106. The tether 109 then passes under the loop 106 and back over the loop 106. The tether is then secured to the hook 108 and drawn tight. This arrangement provides adequate coupling between the towing vehicle and article to be towed. The hook 108 secures the tether 109 and prevents disengagement of the tether 109 from the loop 106.
FIG. 4A shows a rear view of the adapter 100 illustrated in FIGS. 3A-B. As shown, the loop 106 is shown with a circular cross-section and the loop 106 is attached tangentially to the sidewalls 123 of the bracket 104 by welds. Alternatively, other suitable means may be used as desired to attach the loop 106 to the sidewalls 123, including fasteners such as screws or structural components such as openings. The ends 110, 112 of the loop 106 may alternatively be threaded to accept threaded nuts.
FIG. 4B shows a front view of the adapter 100 illustrated in FIGS. 3A-B. According to this view, the loop 106 is secured to the bracket 104 and extends around the hook 108. The indentations 116 of the bracket are visible between the sidewalls 123 of the bracket and the base portion 114 (FIG. 2).
FIG. 4C shows a side view of the adapter 100 illustrated in FIGS. 3A-B. This view better illustrates the arrangement of the hook 108 relative to the loop 106 and bracket 104.
FIG. 5A is a side view shows the hook 108, including base 122 and curved portion 124. The curved portion 124 of the hook 108 is substantially curvilinear and continuous. The base 122 of the hook 108 is substantially flat for mounting to the bracket 104 central of the ends of the loop 106. This hook 108 is useful for securing a tether 109 (FIG. 3B) as described above.
FIG. 5B is a side view of an alternative embodiment of the hook 108 including base 122 and curved portion 124. The hook 108 according to this embodiment includes an angled segment 125 between the curved portion 124 and base 122. This angled segment 125 extends away from the base 122 and provides a gap between the hook 108 and bracket 104. As with the embodiment illustrated in FIG. 5A, the curved portion 124 is substantially semi-circular and the base 122 is substantially flat for mounting to the bracket 104.
Various forms of coupling the tether 109 (FIG. 3B) to the tow adapter 100 are contemplated. This embodiment facilitates attachment of a tether 109 to or around the hook 108. The tether 109 may be a strap, chain, rope or other type of flexible length. The tether 109 may be threaded over and through the loop 106 and attached to the hook 108. The tether 109 is thereby secured against pulling out by the loop 106 and the hook 108. In another embodiment, the tether 109 may pass through the loop 106 and wind about the hook 108, thereby securing the towing vehicle to the device to be towed by means of the tow adapter. Alternatively, the tether 109 may pass over and around the loop 106 and be secured to the hook 108, thereby securing the towing vehicle to the article to be towed by means of both the hook and the loop. In yet another embodiment, the tether 109 may secure to the loop 106 and not to the hook 108, securing the towing vehicle to the article to be towed solely by the loop 106.
The tow adapter may connect the towing vehicle to an article to be towed in other way. Rather than tether 109, the loop of tow adapter may directly attached to the vehicle or may directly engage a separate hook on the device to be towed. Alternatively, a corresponding loop on the device to be towed may engage the hook of the tow adapter. These additional way of attaching a device to be towed illustrate flexibility of tow adapter meeting specific needs.
Other towing apparatus, including chains between a trailer and vehicle frame, may be used in addition to provide redundant safety and security between the article to be towed and the towing vehicle.
Also disclosed is a kit for allowing an individual to adapt a towing vehicle or a device to be towed to include a tow adapter 100 suitable for coupling the device to be towed to the towing vehicle by means of a tether 109. The kit includes a bracket 104 adapted to be attached to a vehicle to support the tow adapter 100 and one or more fasteners 120 suitable to fasten the bracket to the vehicle. The tow adapter 100 includes a loop 106 suitable to support a tether 109 to enable the vehicle to tow a device to be towed. The loop includes first 110 and second 112 ends attached to the bracket 104. A hook 108 is attached to the bracket 104 central of the loop to enable the tether 109 to thread through the loop and attach to the hook 108.
Also disclosed is a method for securing a device to be towed to a towing vehicle. The method includes the step of assembling to a towing vehicle a tow adapter 100 having bracket 104, a loop 106 to support a tether 109, and a hook 108 attached central to the loop 106. The loop 106 includes first 110 and second 112 ends connected to the bracket 104. The method also includes the step of attaching a tether 109 to a device to be towed and threading the tether 109 over and through the loop 106 and attaching the tether 109 to the hook 108. Further according to this method, the tether 109 may be doubled such that the tether 109 reaches from the device to be towed over and through the loop 106, around the hook, and back through the loop 106 to attach to the device to be towed.
