RIGGING TREE
The invention relates to a support structure for storing rigging devices. The support structure comprises a base portion that is mechanically associated with an extension member that extends perpendicularly away therefrom to a distal end. The distal end defines an extension interface configured for being mechanically associated with a rigging cradle. The rigging cradle is configured for receiving rigging items (chains, ropes, slings, wire rope and similar equipment) used to hoist another object. The rigging cradle supports the rigging item so that a lifting hook can be used to lift and remove the rigging item from the rigging cradle while the rigging item is associated with said rigging cradle.
This application claims priority to provisional application 61/933,338, filed on 30 Jan. 2014 and is a continuation in part to application Ser. No. 29/478,387, filed on 3 Jan. 2014 of which the entire contents of all such references are incorporated herein by this reference for all that they disclose for all purposes.
TECHNICAL FIELDThe invention relates to the field of storing lifting devices such as rigging devices including slings, shackles, and hoists.
BACKGROUND OF THE INVENTIONGenerally speaking, as used in this document, “rigging” refers to systems and equipment configured to direct and manipulate force using lines of tension in relation to load bearing anchor points. “Rigging equipment” (devices), therefore, includes a wide variety of tools used for various needs such as equipment used to pull and hoist and/or lift another object. Such objects may be associated with any number of activities such as construction, large material handling, sailing, climbing, theatre, and transportation. Rigging systems that hoist another object typically include chains, ropes (e.g. wire ropes, synthetic materials), manual hoists, shackles, clevis, and similar equipment.
When not in use, the rigging components are stored. Presently, there is a conflict between storage equipment and lifting hooks as it applies to the stowage of slings chains, ropes (e.g. wire ropes, synthetic materials), manual hoists, shackles, clevis and similar lifting equipment. This conflict results in potentially hazardous situations and an unstable or inadequate orientation of the “master link”, making it awkward or unavailable for insertion into a lifting device.
SUMMARY OF THE INVENTIONSome of the objects and advantages of the invention will now be set forth in the following description, while other objects and advantages of the invention may be obvious from the description, or may be learned through practice of the invention.
Broadly speaking, a principle object of the present invention is to provide a support structure for storing rigging items that allows the lifting elements of the lifting device easy access to the rigging items while being stored.
Another object of the present invention is to provide a support structure defining a plurality of rigging item receivers each configured to receive a rigging item and positioned above a plurality of storage areas so that the rigging items being stored extend into and are supported by such storage area.
Another general object of the invention is to provide a support structure extension accessory configured for receiving the lifting elements of lifting devices so that the support structure associated with and storing rigging items may be easily moved.
Still another general object of the invention is to provide a method of making a rigging cradle from a flat piece of material wherein said rigging cradle is configured for receiving rigging items.
For one embodiment a support structure for supporting rigging devices comprises a base portion defining a bottom portion configured to be supported by a support surface such as a floor. An extension member is mechanically associated with the approximate center of the bottom portion and extends perpendicularly away from said bottom portion to define an extension member distal end. Such distal end further defines an extension interface configure for being associated with a rigging cradle.
The support structure further comprises at least one rigging cradle which is/are mechanically associated with the extension interface. A rigging cradle may define a plurality of rigging receivers or just one rigging receiver. Rigging receivers are configured for receiving rigging items such as chains and ropes and slings, etc. Some embodiments will have one rigging cradle that defines a plurality of rigging receivers and some embodiments will have a plurality of rigging cradles each defining at least one rigging receiver. It should be noted that many rigging items define features such as a ring (“master link”) that is configured for receiving lifting elements of a lifting device such as a hook associated with a crane. The rigging receivers are preferably configured to receive the rigging items so that ring is in a position to allow one to easily use the hook of a crane (for example) to remove the rigging item from the rigging receiver.
For yet another embodiment of the invention a method of making a mountable rigging cradle is disclosed. For such method, a flat plate of some “formable” material is used. Formable material is material that can be bent without breaking. The flat plate is cut to define the perimeter outline of a rigging cradle plate. Bend points are defined along the rigging cradle plate. The bending points are preferably symmetrically positioned about the center point of the cradle plate to define two halves that are basically mirror images of each other. The cradle plate is then bent along such bending points to define said rigging cradle.
For one alternative method, before bending the cradle plate at the bending points, the cradle plate is cut along the center point to create two halves. The two halves are then bent along the bending points. Such bending plate halves can be used as is or, preferably, the two halves are mechanically connected back together along the cut to form a one piece structure.
