This disclosure relates to the field cargo securement and, in particular, to an anchor system for a cargo securement strap.
A first representative embodiment of the disclosure is provided. In this embodiment, a releasable anchor system for securing cargo may be provided that includes a frame including a top portion, a first side, and a second side, the first and the second side extending from opposite sides of the top portion. The system further includes a hook receiver coupled to the frame between the first side and the second side. The hook receiver is configured to receive a hook of a cargo securement strap. The system further includes a keeper configured to retain the hook when received upon the hook receiver. The keeper includes a keeper body, a first keeper finger, and a second keeper finger. The first and second keeper fingers extend from opposite sides of the keeper body, and the first and second keeper fingers are rotatably coupled to the first and second side, respectively. The system further includes a stopper bolt coupled between the first side and the second side. The stopper bolt is positioned to contact the first and second keeper fingers in a first position.
In another embodiment, an anchor device for a cargo securement strap is provided that includes a frame configured to engage a mounting track. The anchor device further includes a hook receiver coupled to the frame. The hook receiver is configured to receive a hook of the cargo securement strap. The anchor device further includes a keeper coupled to the frame. The keeper includes a keeper body and at least one keeper finger extending from a side of the keeper body. The keeper is configured to move between a first position and a second position. In the first position, the at least one keeper finger contacts a bolt, and the keeper body is positioned to retain the hook. In the second position, the keeper body is positioned to allow for removal of the hook from the hook receiver.
In yet another embodiment, a method of use for an anchor device of a cargo securement strap is provided. The anchor device is attached to a mounting track of a vehicle. The anchor device includes a frame configured to engage the mounting track. The anchor devices further includes a hook receiver coupled to the frame. The hook receiver is configured to receive a hook of the cargo securement strap. The anchor device further includes a keeper pivotably coupled to the frame. The keeper includes a keeper body and two keeper fingers extending from opposite sides of the keeper body. The keeper is configured to pivot between a first position and a second position. In the first position, the two keeper fingers contact a bolt and the keeper body is positioned to retain the hook. In the second position, the keeper body contacts the bolt, and the keeper is positioned to allow a release of the hook from the hook receiver by pulling the hook downwardly from the hook receiver to free an extended end of the hook from the hook receiver. A handle of the keeper body is pulled causing the keeper to rotate from the first position to the second position. The hook of the cargo securement strap is engaged with the hook receiver. The handle is released causing the keeper to rotate from the second position to the first position due to a force of gravity acting upon the keeper body.
Advantages of the disclosed devices will become more apparent to those skilled in the art from the following description of embodiments that have been shown and described by way of illustration. As will be realized, other and different embodiments are contemplated, and the disclosed details are capable of modification in various respects. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive.
The embodiments may be better understood with reference to the following drawings and description. The components in the figures are not necessarily to scale. Moreover, in the figures, like-referenced numerals designate corresponding parts throughout the different views.
As shown in
The hook receiver 110 may be any landing piece positionable in the frame 108 and configured to receive the hook 106 of the cargo securement strap 102. In the first embodiment, the hook receiver 110 may extend between the first side 118 of the frame 108 and the second side 120 of the frame 108. In one embodiment, the hook receiver 110 may be integral with the frame 108. In alternate embodiments, the hook receiver 110 may be coupled to the frame 108. As shown in
The keeper 112 may be any piece configured to retain and release the hook 106 of the cargo securement strap 102. As shown in
The stopper bolt 114 may be any stopper piece configured to limit a rotation and/or a sliding of the keeper 112. As shown in
As shown in
In further embodiments, as shown in
During operation, the user may attach the anchor device 100 to the mounting track 104 by slidably engaging the slots 128 of the anchor device 100 with the mounting track 104. Because the keeper 112 remains in the first position 142, the user may pull the handle 140 causing the keeper 112 to rotate and/or slide from the first position 142 to the second position 144. When the keeper 112 is rotated and/or slidably moved to the second position 144, the hook 106 of the cargo securement strap 102 may be added to the hook receiver 110. The user may release the handle 140 causing the keeper 112 to return to the first position 142. When the keeper 112 is in the first position 142, the hook 106 is retained by the keeper 112 whether or not a tension is applied to the cargo securement strap 102. If no tension is applied, the hook 106 will be urged by gravity into contact with the top surface 148 of the keeper body 134. The tension may be applied to the cargo securement strap 102 by a cranking device, such as a winch (not shown), that is positioned at an end of the cargo securement strap 102 opposite the hook 106. To remove the hook 106, once the tension is removed from the cargo securement strap 102, the handle 140 may be pulled causing the keeper body 134 to rotate and/or slide from the first position 142 to the second position 144. When the keeper body 134 is rotated and/or slidably moved to the second position 144, the hook 106 may be removed from the hook receiver 110.
In the second embodiment, as shown in
In the second embodiment, the tension sensor module 500 may be configured to detect a force applied by the hook receiver 110 to the underside 516 of the tension sensor module 500. The tension sensor module 500 may be configured to determine a tension of the cargo securement strap 102 based on the force detected. The tension sensor module 500 may be configured to output a signal that is representative of magnitude of the force detected, and/or may be configured to output a signal of whether or not a force is detected, and/or a signal that is representative of a detection of a force equal to or above a given threshold force (upon proper calibration of the tension sensor module 500 with respect to the threshold force level).
The tension sensor module 500 may be configured to transmit the signal to a controller 518 in real-time. In one embodiment, the signal may be indicative of whether an instant tension of the cargo securement strap 102 is greater than or less than a predetermined threshold tension of the cargo securement strap 102. In other embodiments, the signal may be a real-time measurement of the tension in the cargo securement strap 102 (as calibrated) based upon the force sensed by the module 500. In some embodiments, the signal may be an approximate strap tension. In alternate embodiments, the signal may be an exact strap tension. The signal may include a yes/no signal. In some embodiments, the signal that is provided by the sensor 500 may be a signal that is calibrated by a controller 518 (shown schematically in
During operation, due to the tension in the cargo securement strap 102, the hook 106 may be pulled into contact with the bottom side 132 of the hook receiver 110 causing the hook receiver 110 to rotate in the first direction 514 (due to a force being applied to the hook receiver 110 from the hook 106). The hook receiver 110 may rotate and/or slide with respect to the frame 108 until a portion of the hook receiver 110 contacts the underside 516 of the tension sensor module 500, and the tension sensor module 500 may detect the force applied by the hook receiver 110 to the underside 516 of the tension sensor module 500 (such as the magnitude of the force, or the existence of a force as discussed above). The tension sensor module 500 may transmit the signal representative of the force detected to the controller 518.
A releasable anchor system for securing cargo may also be provided. The system may include only the anchor device 100. Alternatively or in addition, the system may include the cargo securement strap 102, the mounting track 104, the hook 106, the crank, the tension sensor module 500, and the controller 518. The tension sensor module 500 may be positioned in the anchor device 100. The anchor device 100 may be mounted on the mounting track 104. The cargo securement strap 102 may be attached to the hook 106 at an end and the crank at an opposite end. The hook 106 may engage the anchor device 100. When the tension is added to the cargo securement strap 102, the tension sensor module 500 may be configured to output the signal to the controller 518. The signal may be representative of the force applied by the hook 106 to the tension sensor module 500.
Each component may include additional, different, or fewer components. For example, the tension sensor module 500 may include a sensor. The sensor may be any device configured to sense the applied force. In some embodiments, the sensor may be a flat disc force sensor, such as the flat disk sensor sold under the trademark FLEXIFORCE™, available from Tekscan, Inc. The tension sensor module 500 may include a circuit board. Additionally, the tension sensor module 500 may be configured to wirelessly transmit signals to a system in a driver cab of a vehicle or to a device such as a laptop, cell phone, tablet, or other system. The system may further be configured for remote connectivity to allow the system to transmit signals to a remote location, such as via an internet or cell phone or other connection.
The methods, systems, and devices described above may be implemented in many different ways and in many different combinations of hardware and software. For example, the controller 518 and/or the tension sensor module 500 may be circuitry that includes an instruction processor, such as a Central Processing Unit (CPU), microcontroller, or a microprocessor; or as an Application Specific Integrated Circuit (ASIC), Programmable Logic Device (PLD), or Field Programmable Gate Array (FPGA); or as circuitry that includes discrete logic or other circuit components, including analog circuit components, digital circuit components or both; or any combination thereof. The circuitry may include discrete interconnected hardware components or may be combined on a single integrated circuit die, distributed among multiple integrated circuit dies, or implemented in a Multiple Chip Module (MCM) of multiple integrated circuit dies in a common package, as examples.
Accordingly, the circuitry may store or access instructions for execution, or may implement its functionality in hardware alone. The instructions may be stored in a tangible storage medium that is other than a transitory signal, such as a flash memory, a Random Access Memory (RAM), a Read Only Memory (ROM), an Erasable Programmable Read Only Memory (EPROM); or on a magnetic or optical disc, such as a Hard Disk Drive (HDD), or other magnetic or optical disk; or in or on another machine-readable medium. A product, such as a computer program product, may include a storage medium and instructions stored in or on the medium, and the instructions when executed by the circuitry in the controller 518 and/or the tension sensor module 500 may cause the controller 518 and/or the tension sensor module 500 to implement any of the processing described above.
The implementations may be distributed. For instance, the circuitry may include multiple distinct system components, such as multiple processors and memories, and may span multiple distributed processing systems. Parameters, databases, and other data structures may be separately stored and managed, may be incorporated into a single memory or database, may be logically and physically organized in many different ways, and may be implemented in many different ways. Example implementations include linked lists, program variables, hash tables, arrays, records (e.g., database records), objects, and implicit storage mechanisms. Instructions may form parts (e.g., subroutines or other code sections) of a single program, may form multiple separate programs, may be distributed across multiple memories and processors, and may be implemented in many different ways.
