  "abstract": "There is provided a multi-leg stand, for photography and the like comprising a vertical main tube, a supporting structure for the vertical main tube comprising a plurality of legs connected to the bottom portion of said vertical main tube and including a plurality of lockable collars rotatably secured around the outer circumference of the vertical main tube and a leg rigidly secured to each of the lockable collars; each leg extends horizontally outwardly from one of the collars and including an outer end portion extending downwardly. At least one of the downwardly extending end portions, comprises a secondary tubular member having an opening at each end designed to securely hold a replaceable member; the replaceable member extends downwardly from the lower end opening thus providing further support for the stand. The stand can thus support either multiple lights or a combination of lights and reflectors or other elements.",
  "claims": [
    "1. A multi-leg stand, comprising: a vertical main tube; a supporting structure comprising a plurality of legs connected to the bottom portion of said vertical main tube and including a plurality of lockable collars secured around the outer circumference of the vertical main tube and a leg rigidly secured to each of the lockable collars; each leg extending horizontally outwardly from one of the collars and including an outer end portion extending downwardly; at least one of the downwardly extending end portions having comprising a secondary tubular member having an opening at each end designed to securely hold a replaceable member; the replaceable member extending downwardly from the lower end opening intended to serve as the contact with the ground.",
    "2. The multi-leg stand of claim 1, further comprising: vertical extension tubes lockably extending from the upper portion of the vertical main tube.",
    "3. The multi-leg stand of claim 1, further comprising: a set of connecting elements mounted along the vertical extension tubes for connecting a lighting fixture or a photographic apparatus to a portion of said main tube.",
    "4. The multi-leg stand of claim 1, further comprising: a telescopically extendable foot extending from the lower opening of the secondary tubular member to permit use on stairs or uneven ground.",
    "5. The multi-leg stand of claim 1, further comprising extending upwardly from the upper end opening of the secondary tubular member a replaceable member capable of holding a photographic unit or accessory distal from the vertical main tube.",
    "6. The multi-leg stand of claim 1, further comprising: a telescoping riser extending upwardly from the upper end opening of the secondary tubular member, for holding a photographic accessory."

  "description_excerpt": "The present invention relates to a stand for use in photography or the like, often referred to as a “C-stand”, having a plurality of rotatable legs to support, in a stable manner, photographic equipment or the like. The plurality of legs can be moved between a position where they are all parallel to one another extending substantially perpendicularly from the support to a variety of angular relationships one to the other. The improved stand further provides for a secondary support position which also can provide for an enhanced stability when the stand is placed on uneven ground or, e.g., on stairs.\n\nThese C-stands, also known as Rocky Mountain stands, are well known in the art as having a plurality, usually at least three, of angularly spaced legs supporting a vertical main tube or column. The three or more legs can, in most such stands, be folded together so that they are all extending parallel from the main tube for ready storage. There is normally provided a locking element that locks the legs into the storage position described above or locks the legs into angularly spaced relationships to each other, around the main tube, to form a stable support.\n\nMany examples of such C-stands can be found with a Google search and are available from a plurality of manufacturers, and sold under the trade names Matthews, Avenger, American, and Rock Solid Master. Such devices are also shown on the following patents: U.S. Pat. Nos. 6,688,565; 9,805,631; and US published application 2003/0029066.",
