Definitions
- the present disclosure relates to a securement device, and in particular, relates to a device for securing load locks used in the trucking industry.
- a trailer portion or a van portion of a truck is loaded so that the contents or cargo optimally occupy the entire volume of the trailer. Under such conditions, the load cannot shift and is completely stable during transit. Many times, however, the trailer carries only a partial load, either because the trailer has been partially loaded to begin with or because some of the cargo has been removed from the trailer before the truck reaches its final unloading destination.
- the cargo load When only part of the total volume of the trailer is filled, the cargo load is subject to shifting into the unloaded portion of the trailer due to vibration, acceleration, braking and turning forces, etc.
- the partial load tends to shift and slide around inside the trailer during transit, which may damage the cargo and the trailer itself.
- the shift of cargo can be so great as to create an unstable load and cause the truck and/or trailer to tip.
- a load lock is a type of cargo restraint device that has a telescoping body that is placed against the partial load and extended between opposite walls of the trailer to prevent the partial load from shifting.
- load locks are elongated, extendible tubes which may be installed transversely between the walls of the trailer compartment and wedged therebetween, to prevent cargo or freight from shifting past the installed load locks.
- a trucker will carry multiple load locks when on a trip in order to secure such cargo loads. It is essential that the load locks be readily accessible to the truck driver in case the need arises to transport a partial load. Since the load locks must be stored for ready access, a significant storage problem arises when load locks are not being used.
- the driver or operator When the load locks are not in use, the driver or operator often stores the load locks on the exterior of the back of the cab of the tractor, particularly in the event that the truck is “deadheading” with no attached trailer.
- Other operators who operate tractors having extenders projecting beyond the cabs of their tractors to improve the aerodynamic characteristics of their trucks, simply jack the unused load lock bars outwardly between the extenders.
- These exposed load locks are subject to theft.
- the driver oftentimes, forgets to store the load lock on the cab and leaves the load locks on a dock. Since the load locks are expensive, the stolen or lost load locks result in increased costs for the trucking operator. Additionally, the stolen or lost load lock prevents the driver from properly restricting the next partial cargo load.
- the load locks may simply be placed on the bed of the trailer.
- This storage method has proven to be inadequate, however, because the load locks tend to slide around on the trailer floor, which may result in damage to both the load locks and the interior of the trailer.
- the loads that are discarded on the bed of the trailer interfere with cargo loading operations and present an unsafe tripping hazard.
- Drivers and truck operators need a device to conveniently and economically store the unused load lock within the trailer while minimizing interference with cargo loading operations within the trailer and minimizing tripping hazards within the trailer.
- the present disclosure relates to a securement device, and in particular, relates to a device for securing load locks in a storage position within a trailer.
- the device comprises a track assembly having a mounting plate attached to the wall.
- the track assembly further includes an upper member and a lower member attached to the mounting plate.
- the upper member and lower member are configured spaced from the mounting plate to form a channel between the upper and lower members and the mounting plate.
- the device further comprises a bracket member having a connector operatively connects to the channel.
- the bracket member includes a fastener that is rotatably connected to the connector and connected to an end of the load lock.
- the fastener is configured to rotatably move the load lock toward the wall of the trailer such that the connector secures the load lock in the storage position near the wall of the trailer.
- the present disclosure also relates to a method storing the load lock within the trailer.
- the method comprises attaching a track assembly to the wall of the trailer and exposing a channel of the track assembly.
- the method also includes providing a bracket member and slidably connecting a connector of the bracket member within the channel.
- An offset member is positioned within the channel wherein the fastener is suspended from the offset member in a spaced relationship from the channel.
- the load lock is connected to the fastener and rotated about the fastener to support the load lock from the connector and near the wall of the trailer.

Description
- Not Applicable.
- Not Applicable.
- The present disclosure relates to a securement device, and in particular, relates to a device for securing load locks used in the trucking industry.
- In the trucking industry, a trailer portion or a van portion of a truck is loaded so that the contents or cargo optimally occupy the entire volume of the trailer. Under such conditions, the load cannot shift and is completely stable during transit. Many times, however, the trailer carries only a partial load, either because the trailer has been partially loaded to begin with or because some of the cargo has been removed from the trailer before the truck reaches its final unloading destination.
- When only part of the total volume of the trailer is filled, the cargo load is subject to shifting into the unloaded portion of the trailer due to vibration, acceleration, braking and turning forces, etc. The partial load tends to shift and slide around inside the trailer during transit, which may damage the cargo and the trailer itself. On some occasions, the shift of cargo can be so great as to create an unstable load and cause the truck and/or trailer to tip.
- As a result, truckers generally use load locks to secure partial loads of cargo within the trailer, thereby effectively confining the cargo to a limited region of the trailer compartment. In general, a load lock is a type of cargo restraint device that has a telescoping body that is placed against the partial load and extended between opposite walls of the trailer to prevent the partial load from shifting. Typically, load locks are elongated, extendible tubes which may be installed transversely between the walls of the trailer compartment and wedged therebetween, to prevent cargo or freight from shifting past the installed load locks.
- Normally, a trucker will carry multiple load locks when on a trip in order to secure such cargo loads. It is essential that the load locks be readily accessible to the truck driver in case the need arises to transport a partial load. Since the load locks must be stored for ready access, a significant storage problem arises when load locks are not being used.
- When the load locks are not in use, the driver or operator often stores the load locks on the exterior of the back of the cab of the tractor, particularly in the event that the truck is “deadheading” with no attached trailer. Other operators, who operate tractors having extenders projecting beyond the cabs of their tractors to improve the aerodynamic characteristics of their trucks, simply jack the unused load lock bars outwardly between the extenders. These exposed load locks, however, are subject to theft. Additionally, the driver, oftentimes, forgets to store the load lock on the cab and leaves the load locks on a dock. Since the load locks are expensive, the stolen or lost load locks result in increased costs for the trucking operator. Additionally, the stolen or lost load lock prevents the driver from properly restricting the next partial cargo load.
- In the case of an empty trailer, the load locks may simply be placed on the bed of the trailer. This storage method has proven to be inadequate, however, because the load locks tend to slide around on the trailer floor, which may result in damage to both the load locks and the interior of the trailer. Further, the loads that are discarded on the bed of the trailer interfere with cargo loading operations and present an unsafe tripping hazard. Drivers and truck operators need a device to conveniently and economically store the unused load lock within the trailer while minimizing interference with cargo loading operations within the trailer and minimizing tripping hazards within the trailer.
- The present disclosure relates to a securement device, and in particular, relates to a device for securing load locks in a storage position within a trailer. The device comprises a track assembly having a mounting plate attached to the wall. The track assembly further includes an upper member and a lower member attached to the mounting plate. The upper member and lower member are configured spaced from the mounting plate to form a channel between the upper and lower members and the mounting plate.
- The device further comprises a bracket member having a connector operatively connects to the channel. The bracket member includes a fastener that is rotatably connected to the connector and connected to an end of the load lock. The fastener is configured to rotatably move the load lock toward the wall of the trailer such that the connector secures the load lock in the storage position near the wall of the trailer.
- The present disclosure also relates to a method storing the load lock within the trailer. The method comprises attaching a track assembly to the wall of the trailer and exposing a channel of the track assembly. The method also includes providing a bracket member and slidably connecting a connector of the bracket member within the channel.

- The present disclosure relates to a securement device. The device can be used for securing any tool. However, for purposes of illustration only, the device will be described for securing a load lock used in securing cargo within a trailer. Components of the device can have a variety of cross sectional shapes such as, but not limited to, elliptical, oval, circular, triangular, square, rectangular or other appropriate geometric configuration. Components of the device can be made of a variety of materials, such as, but not limited to, steel, cast iron, aluminum or plastic. The device can be of any size to accommodate users and trailers of any size and to accommodate load locks of varying diameter cross-sectional shapes and sizes.
- Referring now to the drawings, an over-the-road truck 10 (
FIG. 1 ), which includes atractor 12 and atrailer 14 having acargo compartment 16, is provided with asecurement device 18 of the present disclosure for securing aload lock 20. Thesecurement device 18 comprises abracket member 22 and a track assembly 24 (FIG. 2 ) which are configured to secure theload lock 20 between a restrained position 26 (FIGS. 1 , 2, 3 and 8) and a storage position 28 (FIG. 9 ). - Turning to
FIG. 1 , thetractor 12 has aframe 30 and acab 32 which rests on theframe 30, as well aswheels 34 which support theframe 30 above the road. In addition, thetractor 12 has a fifth wheel assembly (not shown) attached to itsframe 30 in the region of therear wheels 34. The fifth wheel assembly couples thetrailer 14 to thetractor 12. Thetrailer 14 has abed 36 which is reinforced with cross members. Aforward end 38 of thebed 36 rests on the fifth wheel assembly of thetractor 12, whereas the trailingend 40 is supported onwheels 34. Thetrailer 14 has sidewalls 42 and aroof 44 which serve to enclose thecargo compartment 16. - The
load lock 20 is used to stabilize cargo (FIG. 3 ) in thecargo compartment 16 of thetrailer 14 when thecargo compartment 16 is less than completely filled. Theload lock 20 is designed to span thecargo compartment 16 and in effect reduce the size of thecompartment 16 so that cargo will remain stationary during the jolts and other accelerations experienced as thetrailer 14 moves over a roadway. Load locks 20 are commonly tubular shaped, although it is understood that load locks 20 having a square, triangular, or other cross sectional shapes may also be used. Typically, theload lock 20 is cut from steel plate and can be coated to protect the steel from corrosion. - Turning to

The mountingplate 98 is positioned along thesidewall 42 at a height as measured from thebed 36 of thetrailer 14 from about 2 feet to about 6 feet. In an embodiment, the mountingplate 98 is positioned along thesidewall 42 at a height of about 5 feet from thebed 36. Regardless of the installation of this height, the mountingplate 98 positions thesecond side 102 toward the interior of thecargo compartment 16. - The
track assembly 24 further comprises anupper member 112 and alower member 114 that are operatively connected to thesecond side 102 of the mountingplate 98. In an embodiment, aspacer 116 connects theupper member 112 and thelower member 114 to thesecond side 102 of the mountingplate 98. In another embodiment (not shown), theupper member 112 and thelower member 114 connect directly to thesecond side 102 of the mountingplate 98. - The
upper member 112 and thelower member 114 form a spacedchannel 118, wherein thechannel 118 extends generally from therear end 110 to thefront end 108. Thechannels 118 are configured open at the front end of 108 and at therear end 110. Thechannel 118 is sized and shaped to slidably accept theconnector 68 of thebracket member 22. As will be discussed, theconnector 68 slides into the openrear end 110 and travels along thechannel 118. In an embodiment (not shown), thechannel 118 includes friction reducers such as ball bearings to assist movement of theconnectors 68 within thechannel 118. Astop 120 removably connects with therear end 110 of the mountingplate 98. Thestop 120 is configured to temporally close the open end of thechannel 118. Any stop member that closes the end of thechannel 118 is intended to be within the scope of the present disclosure. - The

The slot 122 is fully exposed to thecargo compartment 16 between therear end 110 and thefront end 108. The slot 122 is configured to receive the offsetmembers 72 to allow the remaining portions of thebracket member 22 andconnected load lock 20 to travel with theconnector 68 to continuously position theload lock 20 along different locations within thecargo compartment 16 as will be discussed. - Turning to
FIG. 9 and referring toFIGS. 2-8 , during operation, thesecurement device 18 movably suspends theload lock 20 at the restrained position 26 (FIG. 3 ) and store theload lock 20 against thesidewall 42 in thestorage position 28. As shown, the mountingplates 98 are fastened on the opposingsidewalls 42 of thetrailer 14. For the method of operation, the elements of thesmall tube 50 side ofFIG. 9 will be denoted with a prime symbol ′ to correlate to the opposing elements on side of thelarge tube 48. - During operation, in order to secure the
partial load 46 within thecargo compartment 16, the operator removes thestops 120 from the rear ends 110, 110′ of the mountingplate stop 120 exposes thechannels first end 56 of thelarge tube 48 and connectedbracket member 22 in a position to insert theconnector 68 within thechannel 118 at therear end 110. In particular, the operator positions thefront face 78 of theconnector 68 to face thesecond side 102 of the mountingplate 98. In this position, the offsetmember 72 is positioned within the slot 122 of the mountingplate 98. - The operator rotates the
first end 56 of thelarge tube 48 around thefastener 76 to position thefirst end 62 of thesmall tube 50 near therear end 110′ of the opposing mountingplate 98′. The operator activates theratchet mechanism 52 to extend thesmall tube 50 across thecargo compartment 16 to align theconnector 68′ of thesmall tube 50 with thechannel 118′ at therear end 110′. Theconnector 68′ of thesmall tube 50 is inserted into therear end 110′. In particular, thefront face 78′ of theconnector 68′ is positioned to face thesecond side 102′ of the opposing mountingplate 98′. In this position, the offsetmember 72′ is positioned within the slot 122′ of the opposing mountingplate 98′ to suspend theload lock 20 between the opposing mountingplates cargo compartment 16. - With the
first end 62 of thesmall tube 50 secured to thechannel 118′ of the opposing mountingplate 98′ via itsconnector 68′, the operator slidably moves theload lock 20 along thechannels partial cargo load 46. The offsetmembers bracket members connected load lock 20 to travel within thecargo compartment 16 and toward thepartial cargo load 44. - Regardless of the position of the
partial cargo load 44, the slots 122, 122′ of the mountingplates load lock 20 to any position along thesidewall 42 via thechannels load lock 20, the operator can easily slide theload lock 20 to the desired position snuggly against thepartial cargo load 44. At this position, the operator can further activate theratchet mechanism 52 to extend thesmall tube 50 from thelarge tube 48 till theconnectors second sides plates load lock 20 between thesidewalls 42 of thetrailer 14. - At the desired location of the
load lock 20 positioned against thecargo load 44, the suspendedload lock 20 can be conveniently and safely extended by the operator since the operator does not have to simultaneously lift theload lock 20 and extend theload lock 20 to the final pressurized setting. Instead, the operator can simply adjust theratchet mechanism 52 to set the suspendedtubes - At the desired destination for unloading the
partial cargo 44, the operator slides theload lock 20 away from thecargo 44 via thechannels plates stop 120 positioned at therear end 110′ of thechannel 118′ that holds thesmall tube 50. The operator slides theconnector 68′ of thesmall tube 50 out of thechannel 118′ while leaving the opposingconnector 68 of thelarge tube 48 positioned within itsrespective channel 118. - With the
free connector 68′ of thesmall tube 50, the operator activates theratchet mechanism 52 to retract thesmall tube 50 within thelarge tube 48. Since thefirst end 56 of thelarge tube 48 remains connected to thechannel 118 of its mountingplate 98, the operator can simply let go of theload lock 20. Upon release, thefirst end 56 of thelarge tube 48 rotates around thefastener 76 and theload lock 20 rotates downward under the force of gravity and against thesidewall 42 of thetrailer 14. Theupper member 112 and thelower member 114 hold theconnector 68 in thechannel 118. The offsetmember 72,plate 70,arms 74 andfastener 76 suspend the hangingload lock 20 near thesidewall 42. - Since the
connector 68 of thelarge tube 48 remains operatively connected to thechannel 118, thechannel 118 andconnector 68 secure theload lock 20 for storage against thesidewall 42 for further use. In thissecured storage position 28 for theload lock 20, thecargo 44 is unrestrained for unloading operations. Additionally, theload lock 20 is secured inside thetrailer 14 to eliminate theft opportunities or opportunities to be left forgotten on a loading dock. Further, thecargo compartment 16 of thetrailer 14 is free from anyload locks 20 discarded on thebed 36 to provide a clear and safe path for unloading the cargo from that of thetrailer 14. - Turning to
FIG. 10 , another method of installing thetrack assembly 24 and theload lock 20 is shown. As shown, the opposing mountingplates 98 are removably connected to theroof 44 of thetrailer 14 and to thebed 36 of thetrailer 14 respectively. In this embodiment, the insertion of theconnectors 68 of thebracket members 22 of the first ends 56, 62 of thetubes connector 68 along thetrack assembly 24 remains the same as previously discussed. - Turning to
FIGS. 11 and 12 , another embodiment of the present disclosure is shown. In this embodiment (FIG. 11 ),bracket member 124 includes an I-shapedconnector 126. As shown, theconnector 126 comprises twohorizontal members 128 separated by avertical member 130. Themembers connector 126 has a length as measured between thehorizontal members 128 from about 1 inch to about 4 inches. - Referring to
FIG. 12 , mountingplaten 132 includes anindentation 134 sized and shaped to removably accept the I-shapedconnector 126. As shown, theindentation 134 includes matching horizontal members and vertical member. During operation, the I-shapedconnector 126 pressureably fits within a selected indentation to suspend theload lock 120 within thecargo compartment 44. - The dimensions disclosed are representative of an embodiment and not intended to limit the scope of the disclosure. Any size that is easily used for the intended purpose of the present disclosure is acceptable.
- In view of the above, it will be seen that the several objects of the disclosure are achieved and other advantageous results are obtained. As various changes could be made in the above constructions without departing from the scope of the disclosure, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
