FLEXIBLE LOAD RESTRAINING STRAP
A flexible strap system for securing a load to an elongate support having a mounting bracket with a mount which pivotally secures to an underside of the support. A flexible, inelastic strap connects to the bracket through a pair of strap attachments, with the strap attachments and the mount having a non-colinear orientation on the mounting bracket. A plurality of teeth on the strap engage a ratchet mechanism for tightening the strap around the load. The bracket is rotatable between a first position with the strap generally parallel to the longitudinal axis of the support member and a second position with the strap generally perpendicular to the longitudinal axis of the support member, allowing the strap system to secure loads which are perpendicular or parallel, respectively, to the support.
The present invention relates to load restraining straps, and more particularly, to a flexible load restraining strap which can be pivotably affixed to a support member such as an equipment rack in the bed of a pickup truck.
BACKGROUND OF THE INVENTIONEquipment racks for transporting and/or storing equipment generally include an elongate support member upon which the equipment is placed. For example, pickup trucks and other commercial vehicles often have one or more generally horizontal equipment racks for carrying tools, ladders, lumber and the like. To prevent the supported loads from shifting during transport, it is common to use restraining devices such as bungee cords, rubber straps or rope to secure the loads to the equipment rack. Such restraining devices, however, are awkward to use, are subject to breaking when over-elongated and can cause injury to a user if they snap back during load securing and un-securing operations. Moreover, when not in use, these restraining devices are easily misplaced if not secured to the equipment rack and unsightly if so secured.
Accordingly, there is a need for providing a non-elastic, flexible restraining strap for mounting on an equipment rack such as those supported generally in the bed of a pickup truck.
OBJECT AND SUMMARY OF THE INVENTIONThe invention relates to a flexible load restraining strap system for securing equipment to a rack. The invention includes a mounting bracket which is mounted to an underside of an equipment rack with a pivoting mount and a flexible, inelastic strap which connects at its ends to the mounting bracket. The strap connects to the mounting bracket through strap attachments on the mounting bracket, with the strap attachments and the mount being offset (non-colinear) with respect to each other. The offset orientation of the pivoting mount and the strap attachments allows the mounting bracket to pivot between two positions, a first position with the strap attachments on opposite sides of the rack and a second position with the strap attachments on the same side of the rack.
It is an object of the present invention to provide a flexible load restraining strap formed of an inelastic material.
It is another object of the present invention to provide a flexible load restraining strap which can be readily mounted to the underside of an equipment rack.
It is a further object of the present invention to provide a flexible load restraining strap with a mounting bracket having a pivotable mount and a pair of strap attachments which are non-colinear.
It is another object of the invention to provide a load retention system for securing a load on an equipment rack of a vehicle which is pivotable between a first position with each of the strap attachments on opposite sides of the rack and a second position with each of the strap attachments on the same side of the rack.
It is a further object of the present invention to provide a flexible load restraining strap formed of a plastic material, having teeth and a ratchet mechanism that can be easily tightened to secure a load to an equipment rack and be loosened to release the load.
A further object of the present invention is to provide a flexible load restraining strap which can be used to secure loads which are either parallel or perpendicular to the equipment rack.
These objects are accomplished generally by a flexible load restraining strap system having a mounting bracket, a pivotable mount on the mounting bracket, a pair of strap attachments on the mounting bracket, the pair of strap attachments and the pivotable mount having a non-colinear orientation on the mounting bracket, a flexible, inelastic strap affixed at opposite distal ends to the pair of strap attachments, and a ratchet mechanism adapted to engage with and tighten the strap.
When used to secure a load to an elongate support member such as an equipment rack, the mounting bracket is pivotally secured to the underside of the support member with the mount, with the opposite distal ends of the strap connected to the strap attachments. The load is placed on the support member with the strap encircling the load, and the strap is tightened around the load with the ratchet mechanism.
The present invention is directed to a load retention system for securing a load on a support rack of a vehicle comprising a mounting bracket having a mounting attachment defining a connection of the mounting bracket to the support rack and an axis of rotation of the mounting bracket relative to the support rack, a flexible strap having a first end and a second end and one of the first and second ends being releasably connected to the mounting bracket, a first connection point and a second connection point for attaching the respective first and second ends of the flexible strap to the mounting bracket, at least one of the first and second connection points comprising a releasable strap attachment mechanism supported on the mounting bracket, a first state in which the respective first and second end of the flexible strap is engaged with the strap attachment mechanism, a second state in which the respective first and second end of the flexible strap is released from engagement with the strap attachment mechanism, and wherein the mounting bracket is rotatable about the axis of rotation relative to the support rack between a first position wherein the strap is perpendicularly aligned with the support rack and a second position wherein the strap is aligned in parallel with the support rack.
The present invention is also directed to a method for securing a load on a support rack of a vehicle comprising the steps of securing a mounting bracket to the support rack, the mounting bracket having a mounting attachment defining a connection of the mounting bracket to the support rack and an axis of rotation of the mounting bracket relative to the support rack, releasably connecting a flexible strap having a first end and a second end to the mounting bracket, providing a first connection point and a second connection point on the mounting bracket for attaching the respective first and second ends of the flexible strap to the mounting bracket, making at least one of the first and second connection points a releasable strap attachment mechanism supported on the mounting bracket, defining a first state in which the respective first and second end of the flexible strap is engaged with the strap attachment mechanism, defining a second state in which the respective first and second end of the flexible strap is released from engagement with the strap attachment mechanism, and rotatably attaching the mounting bracket to rotate about the axis of rotation relative to the support rack between a first position wherein the strap is perpendicularly aligned with the support rack and a second position wherein the strap is aligned in parallel with the support rack.
