[0026] Referring initially to the drawings, FIG. 1 illustrates a top perspective view of one possible embodiment of the 5th wheel towing attachment 100 of the present invention. The 5th wheel towing attachment 100 is comprised of a first end 110, a second end 120, and a central frame arm 140, which is preferably made of a structural steel w-section/I-beam. Nonetheless, in differing embodiments of the attachment device 100, the central frame arm 140, first end 110 and second end 120 may be made from other metals such as, but not limited to, stainless steel, steel, aluminum, cast iron, etc., wherein the frame arm 140 may be an integral unit or comprised of multiple units joined together via welds, fasteners, or other suitable attachment means.

[0027] As best shown in FIGS. 1 and 2, the bottom surface 112 of the first end 110 is comprised of a male 5th wheel attachment 1120. As such, the male 5th wheel attachment 1120 allows a user (not shown) to secure the first end 110 of the towing attachment 100 to a first semi-truck 10 via the semi-truck's existing 5th wheel attachment 12 for transport/recovery of a second semi-truck 20, as explained more fully below.

[0028] The first end 110 may also comprise a toolbox/tool tray 118 that allows a user to easily store any tools such as, but not limited to, chains, wrenches, sockets, screwdrivers, etc. that may be needed to repair the towing attachment device 100 and/or the towing or towed semi-truck, or to attach the towing attachment 100 to the towed semi-truck 20. In differing embodiments of the attachment device 100, the toolbox 130 may be additionally comprised of a locking lid 1180 and enclosed system, or an open-air tool tray that may further be comprised of a magnetic base for magnetic attachment to the device 100. The toolbox 118 may also be comprised of a locking mechanism that allows a user to only unlock the contents of the box 118 from within the cab of a semi-truck to prevent theft of the contents of the box 118.

[0029] The first end 110 may also be comprised of a motor housing 1160 for housing a 12v electric motor or air powered motor 116 that may be used to power the hydraulics 156/185 of the towing attachment device 100. The motor housing 1160 may completely enclose or partially enclose the motor 116, thereby allowing a user to gain access to said motor 116 and also protect the motor from inclement weather and debris while the towing attachment 100 is in motion or being stored. The motor 116 can further be controlled by an integrated control panel and/or wirelessly through a wireless remote/mobile application.

[0030] As previously stated, the towing attachment 100 further comprises a saddle assembly 150 that rests on, and is repositionable along, the central frame arm 140. The saddle assembly 150 is comprised of a plurality of generally parallel cross member supports 152, a plurality of generally parallel side walls 154, a plurality of hydraulic arms 156 that attach to the side walls 154 via a plurality of movable hinge points 157, a saddle base 160 and preferably two saddle base channels 164 located on the bottom 162 of the saddle assembly 150. Nonetheless, in differing embodiments of the towing attachment 100, the saddle assembly 150 may also be transferred from one end of the central frame arm 140 by a user via the motor 116, a series of rollers 158 that ride along the top edge 142 or inside 144 of the central frame arm 140 or a hydraulic arm system 146 that may be powered by the electric motor 116 or by the existing airbrake/airline system of the semi-truck 10.

[0031] The plurality of cross member supports 152 and generally parallel side walls 154 of saddle assembly 150 provide stability and structural support to both sides of the saddle assembly 150 on the left and right sides of the central frame arm 140 and can best be observed in FIG. 3. Additionally, the saddle base 160 allows the saddle assembly 150 to make contact with the frame 14/24 of each semi-truck 10/20 in two separate instances. More specifically, the first instance involves the attachment of the towing attachment device 100 to a first semi-truck 10 from a stored/unused position, as shown in FIG. 6A. In this instance, the towing attachment device 100 is attached to the first semi-truck 10 by attaching the male 5th wheel attachment 1120 of the first end 110 to the female 5th wheel attachment 12 of the first semi-truck 10. Once this has occurred, the saddle base 160 can be extended downwards via the hydraulic cylinders 156 towards the frame 14 of the first semi-truck 10 until contact is made on both the left and right sides of the semi-truck 10 frame 14 via the saddle base channels 164. Once in contact with the semi-truck frame 14, both hydraulic arms 156 can continue to be extended against the semi-truck 10 frame 14 until the load of the towing attachment device 100 has been transferred onto the frame 14 of the semi-truck 10, thereby allowing the towing attachment device 100 to be safely transported and eliminating the possibility of the device 100 shearing from the 5th wheel attachment 12 of the semi-truck 10 at the 5th wheel attachment 1120.

[0032] The second instance involves a user connecting the towing attachment device 100 to a second semi-truck 20 after it has already been attached to the first semi-truck 10, as shown in FIG. 6B. To initiate this engagement, the saddle assembly 150 is slid along the central frame arm 140 from the first end 110 to the second end 120 via one of the repositioning means described supra. Then, the saddle base 160 is lowered via the hydraulic arms 156 towards the frame 24 of the second semi-truck 20. Once in contact with the frame 24 of the second semi-truck 20 via the saddle base channels 164, the base 160 of the saddle assembly may be attached to the frame 24 of the second semi-truck 20 using chains 198 or other devices that may also be attached to the towing chain support 180. Then, the hydraulic arms 156 can be retracted upwards, thereby suspending the rear axle(s) of the second semi-truck 20 into the air, and thus allowing for towing of the second semi-truck 20 to occur via the first semi-truck 10.

[0033] As best shown in FIGS. 1, 2, and 5 the towing attachment device 100 may further be comprised of a rear bumper assembly 130. The rear bumper assembly 130 is, in turn, comprised of a pair of vertical support arms 132 and at least one horizontal cross member 134. In differing embodiments, the front surface 1340 of the at least one horizontal cross member 134 can be comprised of a series of reflective signals/indicators 1343, functional brake lights 1344 that are in electrical communication with the braking system of the semi-truck, and/or functional turn signals 1344 that are in electrical communication with the brake light system of the first semi-truck. The bumper assembly 130 is preferably attached to the second end 120 of the central frame arm 140 via a locking pivot pin 136. Accordingly, the locking pivot pin 136 allows the rear bumper assembly 130 to pivot upwards in the event of a rear end collision with the towing attachment device 100 when it is not attached to a second semi-truck 20, thereby mitigating the potential of impacting the windshield of a vehicle that strikes the towing device 100 from the rear. The pivot pin 136 also allows the bumper 130 to be locked in a plurality of orientations/positions to prevent it from interfering with the attachment of the towing attachment device 100 to the second semi-truck 20, as best shown in FIG. 6B.

[0034] FIG. 4 illustrates a perspective view of an alternative embodiment of the 5th wheel towing attachment 100 of the present invention in accordance with the disclosed architecture, wherein removable storage legs 170 are in a fully deployed position. More specifically, in this particular embodiment, the towing attachment device 100 has a plurality of removable legs 170 that attach to the saddle assembly 150 and rear bumper assembly 130. The removable legs 170 have a central vertical frame 172 which may be comprised of a plurality of continuous openings 174 which allow a pin 176 to engage the opening 174 to set the leg 170 at a specific height to allow the device 100 to remain free-standing when not in use via a plurality of feet 178. Therefore, the attachment 100 can be easily attached to a semi-truck without the need for additional users or significant effort. In a differing embodiment of the device 100, the legs 170 may be connected to the air brake/braking system of the semi-truck, which allows the legs 170 to be raised/lowered via a hydraulic assembly 1720 that can be controlled within the cab of the semi-truck or via an external control 171 on some portion of the attachment 100 such as the motor housing 1160.

[0035] In order to attach the device 100 to a semi-truck from its stowed position, a user must simply back the semi-truck up to the device 100, and then attach the device 100 based on the procedures outlined supra. Additionally, this embodiment of the device 100 may further comprise a towing chain support/secondary support 180 as noted above. The support 180 is capable of articulating between 0 and 180 degrees via a plurality of hydraulic arms 185 that may be powered via the electric motor 116 system, or by the existing air brakes/airline of the semi-truck 10. The support 180 is further comprised of a cross member 190 that has a pair of chain attachment loops 195. Said loops 195 allow a user to secure the towing chains 198 that would be attached to the second semi-truck 20 to the device 100, thereby ensuring said chains 198 cannot become dislodged/disconnected from the first semi-truck 10 during the towing/transport procedure. The support member 180 is also capable of articulating in the manner described above to allow the user to create/release tension in the towing chains, and also to aid the saddle assembly 150 in lifting the second semi-truck 20 off of the ground, as best seen in FIG. 6B.

[0036] Notwithstanding the forgoing, the 5th wheel towing attachment 100 of the present invention and its various components can be of any suitable size and configuration as is known in the art without affecting the overall concept of the invention, provided that they accomplish the above-stated objectives.
