The disclosure herein relates to tensioning devices and related methods, and more particularly to a tensioning device having an illumination source permanently affixed to the tensioning device to provide illumination during, among other things, operation of the tensioning device.
Tensioning devices for cargo control are an important tool for warehousemen, contractors, sportsmen, government agencies, and home owners, to name a few, and are used to control and/or secure a variety of materials on many types of vehicles (trucks, cars, aircraft, water vessels), as well as containers such as pallets, crates, and similar types of open devices having materials that may shift or separate from the container during transport or movement of the container.
Tensioning or cargo control devices are numerous and diverse in their material construction and mechanical operation. Cargo control devices include, but not limited to chain, synthetic webbing, rope, cordage, bungee, and an equally diverse family of tensioning devices including cam buckles, over-center buckles, ratchet buckles, winches, wedge blocks, and many other similar type tensioning devices.
Actual use of cargo control devices occur in many different environments, locations, and ambient conditions. Proper attachment and use of the cargo control device is essential to operator safety and containment of the cargo to prevent damage to the cargo and/or the property, and/or injury to people. Proper use involves many factors including cargo control device anchor point selection, hook type, slack or tension, and physical placement on the cargo itself.
Current industry standard tensioning devices employ many features to enhance the mechanics of the actual tie down or secure function offered by the tensioning device, but offer no visual assistance to the user or operator in the form of a visible light to illuminate the work area and assist in the proper placement and use of the cargo control device.
For example, many times a vehicle may be loaded with cargo and the cargo will be secured via a cargo control device during daylight hours, but while the cargo is moved from its point of loading to its final destination the cargo may shift and/or the cargo control device may loosen necessitating adjustment of the cargo control device. Adjustment of the cargo control device may take place under adverse conditions including inclement weather, along a roadside, and during twilight or night time hours when visibility is relatively poor. Typically, in such a scenario, a person will hold a flashlight in one hand, or more often than not hold a light source in their mouth, in a cumbersome and often mistake prone attempt to provide visibility while securing the cargo.
The tensioning device described herein addresses the safety and material control problems by providing a source of illumination directly on the tensioning device. In one embodiment, use of a permanently affixed or “on-board” illumination source disposed on the tensioning device assists the user or operator of the tensioning device in many ways. In this regard, illumination of the illumination source may be provided by one or more light emitting diodes (LED). Prior to installation and use of the tensioning device, the illumination source(s) of the tensioning device may be used to identify a secure anchor point, and to assist the user in macro and micro adjustments of the device while tensioning or releasing the tensioning device. The illumination source(s) may further assist the user in locating proper footing and handholds to avoid slips and falls, and when left in the “on” position after securing the cargo the illumination source(s) may provide illumination to warn other motorists about a potentially dangerous condition.
Further refinement of the illumination source could provide illumination outside the normal visible light spectrum such as infrared illumination for use in operations typically associated with use in military, police, or hunting activities.
Although the tensioning device is described herein as relating to a ratchet type tensioning device, it is understood that other suitable cargo control or tensioning devices and their associated components would benefit from an on-board type illumination source features. In this regard, the scope of the subject matter described herein includes not only a main portion of the tensioning devices with lights, but also envisions, where appropriate, terminal ends of the tensioning device with lights to assist the user in hook-up, release, and generally visibility.
Accordingly, there exists a need for a tensioning device and related method, and more particularly to a tensioning device having an illumination source including a light emitting diode permanently affixed to the tensioning device to provide illumination during, among other things, operation of the tensioning device.
For the purpose of summarizing the invention certain objects and advantages have been described. It is to be understood that not all such objects or advantages may be achieved in accordance with any particular embodiment. Thus, for example, those skilled in the art will recognize that the device described herein may be embodied or carried out in a manner that achieves or optimizes one advantage or group of advantages as taught herein without necessarily achieving other objects or advantages.
In one embodiment the disclosed subject matter includes a tensioning device for securing or containment of cargo, the tensioning device includes an illumination source permanently affixed to the tensioning device and positioned to provide illumination during use of the tensioning device
In another embodiment the disclosed subject matter includes a hand-held manually operated ratchet tensioning device for securing or containment of cargo, the tensioning device includes a main ratchet portion; a terminal end; a strap connected between the main ratchet portion and the terminal end; and an illumination source permanently affixed to the tensioning device, the illumination source includes a light emitting diode disposed positioned to provide illumination during use of the tensioning device.
In still another embodiment the disclosed subject matter includes a method of providing illumination during use of a ratchet tensioning device to secure cargo, the tensioning device having a main ratchet portion linked to a terminal end, the method includes the steps of permanently affixing an illumination source to the tensioning device; and positioning the illumination source to provide illumination during use of the tensioning device.
