The present invention relates to tie-downs for securing a load on a support surface of a vehicle for when the vehicle is transporting the load.
Loads that are transported by vehicles must be secured on or in the vehicle to prevent damage to the load, to the vehicle, and to others due to an unintentional movement of the load relative to the vehicle or partial shifting off of the load from the vehicle or complete dislodgement and falling off of the load from the vehicle during the transporting thereof; and there exist legal requirements to enforce this prevention.
Specifically in the field of transportation, tie-downs are commonly used to so secure loads. However, these tie-downs or components thereof can be readily misplaced. Particularly in the business of equipment rental, auxiliary and supplemental tools such as tie-downs and/or their separate components are too often misplaced, lost, or stolen. Hence, securing the tie-downs themselves would reduce their loss.
Further, some tie-downs can be overly complex. Their deployment and operation to successfully secure a load on a vehicle consumes much time where speedy loading and unloading is a high priority. A tie-down system that reduces the time necessary to fully secure a load on a vehicle would yield faster delivery of the load; and particularly for equipment rental, would increase overall productivity.
Also, greater flexibility of deployment of the tie-downs of a tie-down system would also speed loading and unloading of a load on a transporting vehicle.
An objective of the present invention is to secure a load on a support surface of a vehicle for transporting the load by the vehicle.
Another objective is to quickly so secure the load on the support surface of the transporting vehicle.
Another objective is to selectively mount any number of tie-downs to so secure the load as is necessary.
Another objective is to prevent the loss of the tie-downs from the transporting vehicle.
Another objective is to have less waste of production material of the manufacturing of tie-downs.
These and further objectives are met by the present invention, which is contemplated to encompass the subject matter as claimed herein, that has been described and also shown in the accompanying drawings, and the equivalents that are consonant therewith.
The present invention comprises a tie-down, a pivot, and a vehicle for transporting a load comprising a plurality of the tie-downs. The tie-down comprises the pivot, a winch, and an anchor.
The pivot comprises a pin, and a rotatable sleeve on the pin. In one embodiment, the pin is a generally solid bar, and the pivot further comprises a cap on the first end of the bar, and a base on the second end of the bar. In another embodiment, the pin is a generally solid bar, and the pivot further comprises a cap on the first end of the bar, and a base having an aperture with the bar in the aperture and the base on the bar between the first and second ends of the bar. In another embodiment, the pin is a generally annular tube, and the pivot further comprises a cap on the first end of the tube, and a base on the second end of the tube.
The winch is attached to the sleeve of the pivot. The winch comprises a U-shaped frame comprising two flanges and a wall interconnecting the flanges, and a spindle rotatably mounted on the flanges. The wall is parallel with and attached to the sleeve.
The anchor is attached to the base of the pivot. In one embodiment, the anchor is a generally solid bar. In another embodiment, the anchor is C-shaped. In another embodiment, the anchor comprises two generally C-shaped channels parallel with each other and a part of the pin, when the base of the pivot has an aperture, that is between the base and the second end of the pivot, wherein the channels sandwich that part of the pin. In another embodiment, the anchor is annular.
In one embodiment, the base of the pivot has a minimum transverse dimension, and the anchor has a maximum transverse dimension, wherein the minimum transverse dimension is greater than the maximum transverse dimension. In another embodiment, the base of the pivot has transverse dimensions comprising a width and a length greater than the width, and the anchor has transverse dimensions comprising a first width and a second width greater than the first width, wherein the width of the base is greater than the first width and the length is greater than the second width.
In another embodiment, the base of the pivot comprises a plate having sides that are unequal in length.
The vehicle comprises a support surface for supporting the load when the vehicle is transporting the load, and the plurality of the tie-downs for securing the load on the support surface for when the vehicle is transporting the load. In one embodiment, when the anchor is a generally solid bar, the bar of the anchor is attached to the support surface. In another embodiment, the vehicle further comprises stake pockets adjacent to the support surface, and the anchor is removably mountable within one respective stake pocket for selectively mounting that respective tie-down on the vehicle for securing the load on the support surface for when the vehicle is transporting the load. In another embodiment, the anchor comprises a set of locking holes.
The present invention secures a load 2 to a vehicle 3 that is for transporting the load 2 as shown in
One embodiment of the present invention is shown in
The tie-downs 10, 13, 16, and 19 are identical with each other; and, as such, the tie-down 10 is typical. The tie-down 10 is shown in greater detail in
The tie-down 10 has a pivot 22, a winch 23, and an anchor 24. The pivot 22, the winch 23, and the anchor 24 are each made of suitable structural material, as metal. The winch 23 may be a hand winch 25 as shown. The winch 23 has a generally U-shaped frame 26. The U-shaped frame 26 has two flanges 27 and 29 extending generally perpendicularly from a wall 28 that interconnects the flanges 27 and 29 at proximal ends thereof, thus defining the U shape. The two flanges 27 and 29 have distal ends opposite from both the proximal ends and the wall 28.
Each flange 27 and 29 has an aperture therein. Rotatably mounted within the apertures is a spindle 30 having first and second ends extending beyond the outer surfaces of the flanges 27 and 29. The strap 11 is removably attachable to the spindle 30, as by engagement slots in the spindle 30, so as to be wound and unwound on the spindle 30. Shown as the hand winch 25, the first end of the spindle 30 has a crank 31 attached thereto, as by welding, adjacent to the outer surface of the flange 29. The crank 31 and the first end of the spindle 30 have engagement holes 32 for receiving a hand tool (not shown) for rotating the spindle 30. The second end of the spindle 30 has a rachet 33 attached thereto, as by welding, adjacent to the outer surface of the flange 27. A pawl 34 is mounted, as on a post, on the outer surface of the flange 27 to swivel between a locking position engaging with the rachet 33 to prevent the rachet 33 and the spindle 30 from unwinding, and as shown in
The pivot 22 has a pin 35 and a generally annular sleeve 36 rotatably mounted on the pin 35. The pin 35 is a generally solid bar 37. The bar 37 is longer than the rotatable sleeve 36, and has first and second ends. A cap 38, as a first cap, is attached, as by welding, to the bar 37 on the first end thereof, and a base 39, as a second cap, is attached, as by welding, to the bar 37 on the second end thereof. The cap 38 and the base 39 are plates that each has a minimum transverse dimension, as a diameter when the plates are circular as shown, that is equal to or greater than the maximum transverse dimension, as a diameter as shown, of the rotatable sleeve 36, thereby capturing the rotatable sleeve 36 onto the pin 35 for the rotatable sleeve 36 to freely rotate on the pin 35 about an axis of rotation. The axis of rotation is aligned with the lengths of both the pin 35 and the rotatable sleeve 36.
The wall 28 of the winch 23 is attached to the rotatable sleeve 36, as by welding, thus permitting the winch 23 of the tie-down 10 to be pivotal about the axis of rotation of the rotatable sleeve 36 of the pivot 22. The wall 28 is parallel with the rotatable sleeve 36, in that the wall 28 is adjacent to the rotatable sleeve 36 with the proximal ends of the flanges 27 and 29 that are interconnected by the wall 28 being relatively close to the rotatable sleeve 36 and the distal ends of the flanges 27 and 29 being oppositely and relatively far from the rotatable sleeve 36. Thus, the U-shaped frame 26 has the U shape thereof opening radially outwardly away from the axis of rotation of the rotatable sleeve 36 as shown in
The anchor 24 is a generally solid bar 40 made of suitable structural material, as metal. The bar 40 has first and second ends, and a length defined between the ends. The minimum transverse dimension of the base 39, as a diameter when the base 39 being a plate is circular as shown, is greater than the maximum transverse dimension, as a diameter as shown in
In use, either before or after the load 2 is placed on the support surface 4 of the vehicle 3 for transporting the load 2, the strap 11 is connected to and wound on the spindle 30, as is known in the art. Then, keeping the pawl 34 in its open position, the end of the strap 11 with the attachment 12 is pulled out and away from the tie-down 10, allowing the rotatable sleeve 36 of the pivot 22 to freely rotate to angularly position the winch 23. The attachment 12 is then attached to the desired location on the load 2 when the load 2 is on the support surface 4. The rotatable sleeve 36 thus rotates such that the strap 11 is automatically straight out from the spindle 30 of the winch 23 and perpendicular thereto, as being generally perpendicular by perspective with respect to the wall 28, so as to generate a force that is likewise perpendicular for securing the load 2 to the vehicle 3 through the tie-down 10.
Subsequently, the pawl 34 is swivelled to its locking position, and the hand tool is inserted (not shown) into the engagement holes 32 of the crank 31 to rotate the spindle 30 to rewind the strap 11 onto the spindle 30, the pawl 34 engaging the ratchet 33 and keeping the spindle 30 from unwinding the strap 11 therefrom, thereby tightening the strap 11 to secure the load 2 onto the support surface 4 of the vehicle 3 to prevent the load 2 from unintentionally moving relative to the support surface 4 during the transporting thereof. Typically, a plurality of the tie-downs, although not necessarily all of the tie-downs, of the tie-down system 1 are used, as the tie-downs 10, 13, 16, and 19 as shown in
Another embodiment of the present invention is shown in
The tie-down system 100 comprises a plurality of tie-downs, as tie-downs 110, 111, 112, 113, 114, and 115, that secure the load to the support surface 102 of the vehicle 101. While six tie-downs 110, 111, 112, 113, 114, and 115 are specifically shown in
The tie-downs 110, 111, 112, 113, 114, and 115 are identical with each other; and, as such, the tie-down 110 is typical. The tie-down 110 is shown in greater detail in
The tie-down 110 has a pivot 116, a winch 117, and an anchor 118. The pivot 116, the winch 117, and the anchor 118 are each made of suitable structural material, as metal. The winch 117 may be a hand winch 119 as shown. The winch 117 has a generally U-shaped frame 120. The U-shaped frame 120 has two flanges 121 and 123 extending generally perpendicularly from a wall 122 that interconnects the flanges 121 and 123 at proximal ends thereof, thus defining the U shape. The two flanges 121 and 123 have distal ends opposite from both the proximal ends and the wall 122.
Each flange 121 and 123 has an aperture therein. Rotatably mounted within the apertures is a spindle 124 having first and second ends extending beyond the outer surfaces of the flanges 121 and 123. The strap for the tie-down 110 is removably attachable to the spindle 124, as by engagement slots in the spindle 124, so as to be wound and unwound on the spindle 124. Shown as the hand winch 119, the first end of the spindle 124 has a crank 125 attached thereto, as by welding, adjacent to the outer surface of the flange 123. The crank 125 and the first end of the spindle 124 have engagement holes 126 for receiving a hand tool (not shown) for rotating the spindle 124. The second end of the spindle 124 has a rachet 127 attached thereto, as by welding, adjacent to the outer surface of the flange 121. A pawl 128 is mounted, as on a post, on the outer surface of the flange 121 to swivel between a locking position engaging with the rachet 127 to prevent the rachet 127 and the spindle 124 from unwinding, and as shown in
The pivot 116 has a pin 129 and a generally annular sleeve 130 rotatably mounted on the pin 129. The pin 129 is a generally solid bar 131. The bar 131 is longer than the rotatable sleeve 130, and has first and second ends. A cap 132, as a first cap, is attached, as by welding, to the bar 131 on the first end thereof, and a base 133, as a second cap, is attached, as by welding, to the bar 131 on the second end thereof. The cap 132 is a plate that has a minimum transverse dimension, as a diameter when the plate is circular as shown, that is equal to or greater than the maximum transverse dimension, as a diameter as shown, of the rotatable sleeve 130. The base 133 is a plate having transverse dimensions that are unequal transverse width and transverse length, greater than the transverse width, as shown in
The wall 122 of the winch 117 is attached to the rotatable sleeve 130, as by welding, thus permitting the winch 117 of the tie-down 110 to be pivotal about the axis of rotation of the rotatable sleeve 130 of the pivot 116. The wall 122 is parallel with the rotatable sleeve 130, in that the wall 122 is adjacent to the rotatable sleeve 130 with the proximal ends of the flanges 121 and 123 that are interconnected by the wall 122 being relatively close to the rotatable sleeve 130 and the distal ends of the flanges 121 and 123 being oppositely and relatively far from the rotatable sleeve 130. Thus, the U-shaped frame 120 has the U shape thereof opening radially outwardly away from the axis of rotation of the rotatable sleeve 130 as shown in
The anchor 118 is a channel 134 that is transversely cross-sectionally generally C-shaped. The C-shaped channel 134 has transverse dimensions of the C shape that are unequal transverse widths, with a second transverse width of the C shape being greater than a first transverse width of the C shape as shown in
As shown in
The anchor 118 is removably mountable within any one of the stake pockets of the sets 103 and 104 of stake pockets of the vehicle 101, for selectively mounting the tie-down 110 on the vehicle 101 for securing the load on the support surface 102 for when the vehicle 101 is transporting the load, by inserting the second end of the C-shaped channel 134 of the anchor 118 into the stake pocket. The transverse width and the transverse length of the rectangular plate of the base 133 is greater than the inner dimensions of any one of the stake pockets of the sets 103 and 104 of stake pockets. The opposite side surface 136 therefore rests on top of the stake pocket into which the anchor 118 of the tie-down 110 is inserted as shown in
In use, either before or after the load is placed on the support surface 102 of the vehicle 101 for transporting the load, one stake pocket is chosen and the tie-down 110 is mounted on the vehicle 101 by inserting the second end of the anchor 118 into the one stake pocket. The tie-down 110 is so inserted until the base 133 rests on top of the one stake pocket as shown in
After the tie-down 110 is so mounted, and after the load is placed on the support surface 102 of the vehicle 101 for transporting the load, the strap is connected to and wound on the spindle 124, identically as shown in
Subsequently, the pawl 128 is swivelled to its locking position, and the hand tool is inserted (not shown) into the engagement holes 126 of the crank 125 to rotate the spindle 124 to rewind the strap onto the spindle 124, the pawl 128 engaging the ratchet 127 and keeping the spindle 124 from unwinding the strap therefrom, thereby tightening the strap to secure, identically as shown in
Yet another embodiment of the present invention is shown in
The tie-down system 200 comprises a plurality of tie-downs, as similarly as the plurality shown in
The tie-downs are identical with each other; and, as such, the tie-down 210 is typical. The tie-down 210 is shown in greater detail in
The tie-down 210 has a pivot 211, a winch 212, and an anchor 213. The pivot 211, the winch 212, and the anchor 213 are each made of suitable structural material, as metal. The winch 212 may be a hand winch 214 as shown. The winch 212 has a generally U-shaped frame 215. The U-shaped frame 215 has two flanges 216 and 218 extending generally perpendicularly from a wall 217 that interconnects the flanges 216 and 218 at proximal ends thereof, thus defining the U shape. The two flanges 216 and 218 have distal ends opposite from both the proximal ends and the wall 217.
Each flange 216 and 218 has an aperture therein. Rotatably mounted within the apertures is a spindle 219 having first and second ends extending beyond the outer surfaces of the flanges 216 and 218. The strap for the tie-down 210 is removably attachable to the spindle 219, as by engagement slots in the spindle 219, so as to be wound and unwound on the spindle 219. Shown as the hand winch 214, the first end of the spindle 219 has a crank 220 attached thereto, as by welding, adjacent to the outer surface of the flange 218. The crank 220 and the first end of the spindle 219 have engagement holes 221 for receiving a hand tool (not shown) for rotating the spindle 219. The second end of the spindle 219 has a rachet 222 attached thereto, as by welding, adjacent to the outer surface of the flange 216. A pawl 223 is mounted, as on a post, on the outer surface of the flange 216 to swivel between a locking position engaging with the rachet 222 to prevent the rachet 222 and the spindle 219 from unwinding, and as shown in
The pivot 211 has a pin 224 and a generally annular sleeve 225 rotatably mounted on the pin 224. The pin 224 is a generally solid bar 226. The bar 226 is longer than the rotatable sleeve 225, and has first and second ends. A cap 227 is attached, as by welding, to the bar 226 on the first end thereof. A base 228 has an aperture as shown in
The cap 227 is a plate that has a minimum transverse dimension, as a diameter when the plate is circular as shown, that is equal to or greater than the maximum transverse dimension, as a diameter as shown, of the rotatable sleeve 225. The base 228 is a plate having transverse dimensions that are unequal transverse width and transverse length, greater than the transverse width, as shown in
The wall 217 of the winch 212 is attached to the rotatable sleeve 225, as by welding, thus permitting the winch 212 of the tie-down 210 to be pivotal about the axis of rotation of the rotatable sleeve 225 of the pivot 211. The wall 217 is parallel with the rotatable sleeve 225, in that the wall 217 is adjacent to the rotatable sleeve 225 with the proximal ends of the flanges 216 and 218 that are interconnected by the wall 217 being relatively close to the rotatable sleeve 225 and the distal ends of the flanges 216 and 218 being oppositely and relatively far from the rotatable sleeve 225. Thus, the U-shaped frame 215 has the U shape thereof opening radially outwardly away from the axis of rotation of the rotatable sleeve 225 as shown in
The anchor 213 has a first channel 231 that is transversely cross-sectionally generally C-shaped, and a second channel 232 that is transversely cross-sectionally generally C-shaped, and the second part 230 of the pin 224 that is between the base 228 and the second end of the bar 226. The first C-shaped channel 231 and the second C-shaped channel 232 are parallel with each other and are in between the base 228 and the second end of the bar 226 as shown in
The anchor 213 is thus transversely generally rectangular. The anchor 213 has transverse dimensions that are unequal transverse widths, with a second transverse width being greater than a first transverse width as shown in
As shown in
The anchor 213 also has a set 237 of locking holes. The set 237 of locking holes form an aperture 238 passing entirely through the second, greater transverse width of the anchor 213 approximately adjacent but spaced from the second end of the anchor 213. A locking pin 239 may be inserted through the aperture 238 to prevent the tie-down 210 from being accidentally removed or dislodged from the stake pocket, as stake pocket 203 as shown in
The anchor 213 is removably mountable within any one of the stake pockets of the vehicle 201, for selectively mounting the tie-down 210 on the vehicle 201 for securing the load on the support surface 202 for when the vehicle 201 is transporting the load, by inserting the second end of the anchor 213 into the stake pocket, as 203 as shown in
In use, either before or after the load is placed on the support surface 202 of the vehicle 201 for transporting the load, one stake pocket 203 is chosen and the tie-down 210 is mounted on the vehicle 201 by inserting the second end of the anchor 213 into the one stake pocket 203. The tie-down 210 is so inserted until the base 228 rests on top of the one stake pocket 203 as shown in
After the tie-down 210 is so mounted, and after the load is placed on the support surface 202 of the vehicle 201 for transporting the load, the strap is connected to and wound on the spindle 219, identically as shown in
Subsequently, the pawl 223 is swivelled to its locking position, and the hand tool is inserted (not shown) into the engagement holes 221 of the crank 220 to rotate the spindle 219 to rewind the strap onto the spindle 219, the pawl 223 engaging the ratchet 222 and keeping the spindle 219 from unwinding the strap therefrom, thereby tightening the strap to secure, identically as shown in
Still yet another embodiment of the present invention is shown in
The tie-down system 300 comprises a plurality of tie-downs, as similarly as the plurality shown in
The tie-downs are identical with each other; and, as such, the tie-down 310 is typical. The tie-down 310 is shown in greater detail in
The tie-down 310 has a pivot 311, a winch 312, and an anchor 313. The pivot 311, the winch 312, and the anchor 313 are each made of suitable structural material, as metal. The winch 312 may be a hand winch 314 as shown. The winch 312 has a generally U-shaped frame 315. The U-shaped frame 315 has two flanges 316 and 318 extending generally perpendicularly from a wall 317 that interconnects the flanges 316 and 318 at proximal ends thereof, thus defining the U shape. The two flanges 316 and 318 have distal ends opposite from both the proximal ends and the wall 317.
Each flange 316 and 318 has an aperture therein. Rotatably mounted within the apertures is a spindle 319 having first and second ends extending beyond the outer surfaces of the flanges 316 and 318. The strap for the tie-down 310 is removably attachable to the spindle 319, as by engagement slots in the spindle 319, so as to be wound and unwound on the spindle 319. Shown as the hand winch 314, the first end of the spindle 319 has a crank 320 attached thereto, as by welding, adjacent to the outer surface of the flange 318. The crank 320 and the first end of the spindle 319 have engagement holes 321 for receiving a hand tool (not shown) for rotating the spindle 319. The second end of the spindle 319 has a rachet 322 attached thereto, as by welding, adjacent to the outer surface of the flange 316. A pawl 323 is mounted, as on a post, on the outer surface of the flange 316 to swivel between a locking position engaging with the rachet 322 to prevent the rachet 322 and the spindle 319 from unwinding, and as shown in
The pivot 311 has a pin 324 and a generally circularly annular sleeve 325 rotatably mounted on the pin 324. The pin 324 is a generally circularly annular tube 326. The annular tube 326 is longer than the rotatable sleeve 325, and has first and second ends. A cap 327, as a first cap, is attached, as by welding, to the annular tube 326 on the first end thereof, and a base 328, as a second cap, is attached, as by welding, to the annular tube 326 on the second end thereof. The cap 327 is a plate that has a minimum transverse dimension, as a diameter when the plate is circular as shown, that is equal to or greater than the maximum transverse dimension, as a diameter as shown, of the rotatable sleeve 325. The base 328 is a plate having transverse dimensions that are unequal transverse width and transverse length, greater than the transverse width, as shown in
The wall 317 of the winch 312 is attached to the rotatable sleeve 325, as by welding, thus permitting the winch 312 of the tie-down 310 to be pivotal about the axis of rotation of the rotatable sleeve 325 of the pivot 311. The wall 317 is parallel with the rotatable sleeve 325, in that the wall 317 is adjacent to the rotatable sleeve 325 with the proximal ends of the flanges 316 and 318 that are interconnected by the wall 317 being relatively close to the rotatable sleeve 325 and the distal ends of the flanges 316 and 318 being oppositely and relatively far from the rotatable sleeve 325. Thus, the U-shaped frame 315 has the U shape thereof opening radially outwardly away from the axis of rotation of the rotatable sleeve 325 as shown in
The anchor 313 is a generally rectangularly annular tube 329. The annular tube 329 has transverse dimensions that are unequal transverse widths, with a second transverse width being greater than a first transverse width as shown in
As shown in
The anchor 313 also has a set 332 of locking holes. The set 332 of locking holes form an aperture 333 passing entirely through the second, greater transverse width of the annular tube 329 of the anchor 313 approximately adjacent but spaced from the second end of the annular tube 329. A locking pin 334 may be inserted through the aperture 333 to prevent the tie-down 310 from being accidentally removed or dislodged from the stake pocket, as stake pocket 303 as shown in
The anchor 313 is removably mountable within any one of the stake pockets of the vehicle 301, for selectively mounting the tie-down 310 on the vehicle 301 for securing the load on the support surface 302 for when the vehicle 301 is transporting the load, by inserting the second end of the anchor 313 into the stake pocket, as 303 as shown in
In use, either before or after the load is placed on the support surface 302 of the vehicle 301 for transporting the load, one stake pocket 303 is chosen and the tie-down 310 is mounted on the vehicle 301 by inserting the second end of the anchor 313 into the one stake pocket 303. The tie-down 310 is so inserted until the base 328 rests on top of the one stake pocket 303 as shown in
After the tie-down 310 is so mounted, and after the load is placed on the support surface 302 of the vehicle 301 for transporting the load, the strap is connected to and wound on the spindle 319, identically as shown in
Subsequently, the pawl 323 is swivelled to its locking position, and the hand tool is inserted (not shown) into the engagement holes 321 of the crank 320 to rotate the spindle 319 to rewind the strap onto the spindle 319, the pawl 323 engaging the ratchet 322 and keeping the spindle 319 from unwinding the strap therefrom, thereby tightening the strap to secure, identically as shown in
The embodiments of the present invention may be made by any method. Preferably, because hand winches are widely available, a premanufactured hand winch may be the basis for the winch of any of the embodiments of the present invention. Portions of the premanufactured hand winch may be disassembled or cut off, and reassembled or reattached to form the winch of any of the embodiments of the present invention. Preferably, the interconnecting wall of a U-shaped frame of a premanufactured winch may be cut off therefrom and reattached, as by welding, to form the U-shaped frame in accordance with the winch of any of the embodiments of the present invention. This newly made U-shaped frame then is attached to the rotatable sleeve of the pivot of the tie-down in accordance with the present invention.
