The present disclosure relates to safety restraints for use with merchandise. More particularly the present disclosure relates to safety restraints for use within truck storage compartments and store shelving.
Transporting inventory in trucks is difficult as merchandise tends to shift during travel. For example, boxes of items may be neatly stacked on top of one another when loaded into a truck storage compartment, but begin to shift as a truck turns or hits bumps along the road. It is then difficult to unload these boxes or items without damage. Additionally, certain items may break or become contaminated during shipping. The movement of items also presents a danger to employees during unloading, as items may become unstable and fall on the employees, or fall to the ground and become a tripping hazard.
Similar problems are also prevalent in the retail industry where items are often stacked on shelving. In certain instances, items tend to fall from the shelves and injure customers or employees. For example, stacked items may become unstable when one item is removed, and the remaining stack may fall on a customer or employee at a later time.
Ropes and other solutions have been used but they can become entangled. Additionally, it is often too cumbersome and too time-consuming to secure items with rope and to untie knots each time to release the merchandise. Rope is also often too thin and flimsy to properly secure large items. Thus, it would be beneficial to provide a safety restraint system to be used during shipping and storage to keep merchandise secured, and reduce the risk of harm to employees and the public.
In some embodiments, a safety restraint device includes an inner core, a spring disposed around the inner core and having a relaxed condition and an stretched condition, an outer shaft disposed around the spring, a housing disposed around the outer shaft, the outer shaft being rotatable within the housing, a moveable member translatable relative to the housing, and a body coupled to the outer shaft at a first end, and to the moveable member at a second end, the body having a length from the first end to the second end, and a width perpendicular to its length, the width of the body being approximately equal to a height of the housing, the body being wrapped around the outer shaft when the spring is in the relaxed condition.

Various embodiments of the presently disclosed connectors are disclosed herein with reference to the drawings, wherein:
Various embodiments of the present invention will now be described with reference to the appended drawings. It is to be appreciated that these drawings depict only some embodiments of the invention and are therefore not to be considered limiting of its scope.
Despite the various improvements that have been made to shipping and storage solutions, conventional methods suffer from some shortcomings as discussed above.
There therefore is a need for further improvements to the devices and methods of safely shipping, storing and displaying inventory items, merchandise, products, boxes, tools and other items that would benefit from being more safely handled. Among other advantages, the present disclosure may address one or more of these needs.
Two clamps 106 are attached to L-shaped brackets 107, which in turn are attached to housing 102. In some examples, each clamp 106 is in the form of an E-clip to be used with an E-track system that is attached to a truck's inner walls. It will be understood that in some examples, only one clamp 106 may be used, and that clamps 106 may be directly coupled to housing 102 instead of being attached via brackets 107. Clamps 106 may serve to fix housing 102 in a certain location within the storage compartment (e.g., maintain housing 102 in a position against a wall).
A rotatable wheel 108 may be disposed adjacent lower cap 101L and operatively coupled to one of gears 109, which in turn is coupled to outer shaft 105. Wheel 108 may include indentations so that it is easily manipulated by a user. On the opposite side of housing 102, adjacent upper cap 101U and across from wheel 108 is locking pin 111. In some embodiments, one of gears 109 includes one or more holes disposed around its circumference and locking pin 111 may be pressed into a hole of the gear to prevent any rotation of outer shaft 105 relative to housing 102. As shown in this example, locking pin 111 is disposed above the upper cap 101U and extends in the vertical direction (Y-direction). Alternatively, locking pin 111′ may be disposed horizontally and extend in the X-direction through an opening in housing 102. Such a locking pin 111′ may be disposed anywhere on the circumference of housing 102 (e.g., on one side as shown in phantom lines, or on the opposite side, closer to clamps 106.
An extendable and retractable body 110 is coupled at one end to outer shaft 105 and at an opposing end to moveable member 112. Body 110 may be formed of netting and may include rope, thread, twine, nylon strands or other strings that are interwoven together to form a body having a plurality of apertures as shown. Suitable materials for body 110 may include yarn, fabric, nylon, rope, metal wire, or any suitable combination thereof. Alternatively, body 110 may be formed of a canvas or other sheet including or not including apertures, instead of a conventional netting. Body 110 may also be translucent so that merchandise is clearly visible when secured behind the body. Body 110 may be capable of wrapping around outer shaft 105 and being retracted and entirely disposed within housing 102 when the device 100 is in the entirely closed or retracted configuration. Additionally, as shown, body 110 may include a first group of filaments traveling in a first direction, and a second group of filaments that cross the first group of filaments. In at least some embodiments, the first group and the second group of filaments are perpendicular. Alternatively, the groupings may cross one another to form diamond-shaped apertures as shown.
Moveable member 112 may be formed of a metal, plastic or other suitable material (e.g., any material similar to that of housing 102, such as a pvc pipe) and as discussed above, is coupled to one end of the body 110 so that body 110 is stretchable between moveable member 112 and housing 102 and is extendable in the direction “X”. Two connectors 120 are coupled near opposing ends of moveable members, and a handle 130 is disposed approximately halfway between the two connectors 120. It will be understood that any number of connectors 120 may be disposed on moveable member 112, including a single connector or three or more connectors. In some examples, connectors 120 are in the form of E-clips as shown to be used with an E-track system. In this example, connector 120 includes a first end 121 that falls into an aperture of the track system, a second end 122 opposite the first end, and a pivoting locking arm 123. Each connector 120 may be aligned with a top and a bottom of the housing and may be equally spaced from handle 130.
In one variation (
Safety restraint device 100 may include a fully retracted condition, a fully expanded condition, and a number of partially expanded conditions between the fully expanded and the fully retracted conditions. A partially expanded condition is shown in
As shown in
When the user wishes to remove the device, he may simply release locking pin 111 to allow the gears to turn. With no external force applied to the system, spring 104 will return to its relaxed state, pulling body 110 into housing 102 to wrap around outer shaft 105 as the user guides the body gently into the housing by holding handle 130. It will be understood that the diameter of housing 102 will be proportional to the length of the body. For example, a 60-foot body will require a relatively larger housing, while a 3-foot body will require a relatively smaller housing. In at least some examples, housing 102 has a diameter of between 6 inches and 18 inches. In at least some examples, housing 102 has a diameter of approximately 12 inches.
The safety restraint device may also be used in warehouses and retail stores to ensure that items do not become damaged or injure customers and/or employees.
