FIELD OF THE INVENTION
The present invention relates generally to pole supports for providing lateral support for free standing poles, and in particular to universal multidirectional pole support apparatus.
BACKGROUND OF THE INVENTION
Many free standing poles and posts would benefit from lateral support. However, known lateral support apparatus are fixed length for use in a specific situation. Known variable length lateral support apparatus utilize a two-part support rod that adjusts either by telescoping one inside the other, or bolting the two parts together in different configurations. The fixed length design is limited to specific applications, while the more general purpose variable length design is bulky and awkward.
Furthermore, attachment means at the ends of known lateral support apparatus are limited to specific angular and rotational orientations relative to the support rod there between. Additionally, the attachment means are generally limited to a single specific type of attachment. Known lateral support apparatus fail to provide true universality of application.
SUMMARY OF THE INVENTION
The present invention is a novel universal support apparatus includes a permanently bendable support rod having one of a pair of anchors secured to each end, and a pair of fasteners that cooperate with the anchors for connecting the support rod between an external structure, such as but not limited to a free standing pole or post, and an adjacent fixed structure such as a floor or wall. Each anchor is formed of a substantially rigid foot having inner and outer arced surfaces, an aperture formed through the foot, and a rod connector structured for securing the anchor to one end of the support rod. The pair of fasteners are each operable through the aperture of the foot of one of the anchors.
According to one aspect of the novel universal support apparatus, the ends of the support rod are a slip fit with the rod connectors in the anchors and are rotatable therein until secured by gripping means. Furthermore, the support rod is composed of a solitary nonextensible member of unitary single-piece construction having a substantially uniformly solid cross-section extended substantially continuously between opposing first and second end portions, and is substantially independently permanently bendable in three dimensions along substantially an entire length thereof between the end portions secured to the rod connectors of the anchors.
Other aspects of the invention are detailed herein.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
In the Figures, like numerals indicate like elements.
FIG. 1 illustrates a support leg 10 for providing lateral support to an external structure 12, such as but not limited to a free standing pole or post. By example and without limitation, structure 12 is a pole or post that is mounted free standing in an automobile or other vehicle 14. Support leg 10 is formed of a permanently bendable support arm 16 anchored at either end 18 by a pair of anchors 22. By example and without limitation, support leg 10 provides lateral support to free standing structure 12 by anchoring to an adjacent surface 24 of vehicle 14, such as a floor, wall or other structural portion of vehicle 14.
Permanently bendable support arm 16 is of the type disclosed in issued U.S. Pat. No. 7,481,404, and U.S. Pat. No. 7,959,116, the complete disclosures of which are all incorporated herein by reference. Accordingly, permanently bendable support arm 16 is composed, by example and without limitation, of a solitary nonextensible elongated metal rod of single-piece construction having a substantially uniformly solid cross-section extended substantially continuously between opposing end portions 18 and being independently permanently bendable in three orthogonal dimensions along substantially an entire length between end portions 18. Support arm 16 is formed of permanently bendable aluminum or aluminum alloy with a substantially constant diameter of about 1⁄2 inch, but at least in the range of about 1⁄8 inch, 1⁄4 inch or 3⁄8 inch to about 1 inch. Support arm 16 is alternatively realized in steel, copper, permanently bendable copper alloys or another permanently bendable metal or rigid plastic material without limiting the practice of the invention. Support arm 16 is not limited to rods having round cross-sections; rather, support arm 16 is alternatively realized having a square, rectangular, hexagonal, octagonal or other alternative cross-section. By example and without limitation, permanently bendable support arm 16 is illustrated as having different contiguous and interconnected bent portions 26 and substantially straight portions 28 permanently formed along its elongated length between end portions 18.
Anchors 22 include a substantially rigid part circular curved foot 30 formed along a curving arc 32 and defining inner and outer substantially mutually concentric curved or arced surfaces 34, 36. Outer curved surface 36 is offset from inner curved surface 34 by a substantially continuous solid thickness of material 38. One or more apertures 40 are formed through the substantially continuous solid thickness of material 38 substantially along the curve of foot 30. According to one embodiment, aperture 40 is a single curved slot through the thickness of material 38 and extended along curving arc 32 of curved foot 30. A rod connector 42 is structured for securing support arm 16 to foot 30. By example and without limitation, rod connector 42 is extended from one end of arc 32 of curved foot 30 and is optionally substantially tangent therewith. Respective rod connectors 42 secure the pair of anchors 22 to end portions 18 of support arm 16.
A fastener 44 is structured for cooperating with aperture 40 for securing external structure 12 to one of inner arced surface 34 of one anchor 22, while a different fastener 44 is structured for cooperating with aperture 40 for securing outer arced surface 36 of a different anchor 22 to adjacent portion 24 of vehicle 14.
FIGS. 2-5 are different views that illustrate support leg 10 coupled for providing lateral support to free standing external structure 12. As illustrated, anchors 22 are rotatable (arrow 46) about respective end portions 18 of support arm 16. Anchors 22 are, therefore, positionable on any adjacent inclined vehicle surface, as well as any horizontal floor or upright wall surface 24. For example, FIGS. 2 and 5 illustrate anchor 22 (right) mounted on an inclined adjacent surface 24 of vehicle 14. Furthermore, curvature of arced surfaces 34, 36 ensures that foot 30 of anchors 22 is securable to adjacent surface 24 with respective rod connectors 42 extended within a range of angles 48 that permit locating anchor 22 in tight spaces, and minimize bending of arm 16.
FIG. 6 is a view of anchor 22 looking at inner arced surface 34. Aperture 40 is a single curved slot through the thickness of material 38 and extended along curving arc 32 of curved foot 30 and is sized to receive there through cooperating fastener 44. Here, fastener 44 is shown as a conventional threaded screw or bolt. Washer 50 is optionally provided between fastener 44 and foot 30.
Rod connector 42 is shown as being extended substantially tangentially from arc 32 of curved foot 30. By example and without limitation, rod connector 42 is shown as having a longitudinal cavity 52 that is sized to slidingly receive a short distance thereinto either of end portions 18 of support arm 16, and gripping means 54 for gripping arm end portions 18. For example, gripping means 54 is a threaded gripping means embodied as a clamp joint formed of a split collar 56 tightened by a threaded fastener 58 operating across a split 60 and applied to an internally threaded aperture 62. Tightening of fastener 58 closes split 60 in collar 56 and squeezes cavity 52 about end portions 18 of support arm 16. Thereafter, end portions 18 of support arm 16 cannot be slidingly removed from cavity 52 and are rendered nonrotatable.
According to one embodiment, collar 56 having gripping means 54 formed therein is formed integrally with curved foot 30 of anchor 22, as by molding, casting or machining. Support arm 16 is mated directly to anchor 22 by rod connector 42. Accordingly, longitudinal cavity 52 is formed directly in anchor 22 through rod connector 42.
FIG. 7 is a view of anchor 22 looking at outer arced surface 36. Slot aperture 40 is extended along curving arc 32 of curved foot 30 for receiving there through cooperating fastener 44. Here, fastener 44 is shown as a conventional U-bolt with a pair of nuts 64 threaded onto threaded shaft ends 66. Washers 50 are optionally provided between nuts 64 and foot 30. Additionally, a portion 68 of curved foot 30 is recessed from outer arced surface 36 around slot aperture 40 so that shaft ends 66 of U-bolt fastener 44 do not extend excessively beyond outer arced surface 36.
FIG. 8 is a perspective view of anchor 22 looking at thickness of material 38 between inner and outer substantially mutually concentric curved or arced surfaces 34, 36.
FIG. 9 shows fastener 44 is shown as a conventional U-bolt fitted around external structure 12, such as but not limited to a free standing pole or post. Nuts 64 are threaded onto threaded shaft ends 66. Washers 50 are optionally provided between nuts 64 and foot 30. Aperture 40 is a single curved slot through the thickness of material 38 so as to accept fastener 44 embodied as either U-bolt (shown here) or screw (shown in FIG. 6). Here, washers 50 and nuts 64 are recessed into recessed portion 68 of curved foot 30. Additionally, protective caps 70 are shown fitted over shaft ends 66.
End portion 18 of support arm 16 is shown slidably received into cavity 52 of rod connector 42. Arm end portion 18 is rotatable (arrow 46) in cavity 52 until secured by tightening of gripping means 54.
FIG. 10 is a detailed view of rod connector 42 of anchor 22. Here, rod connector 42 includes split collar 56 forming therein internal cylindrical cavity 52 truncated by foot 30. Truncated cylindrical cavity 52 is sized to slip over end portion 18 of support arm 16. Split 60 is substantially parallel with longitudinal cavity 52, whereby a longitudinal opening is formed. A pair of bosses 72, 74 cooperate with threaded fastener 58 as gripping means 54. Near boss 72 is pierced with a clearance aperture 76 for fastener 58, while far boss 74 is provided with internally threaded aperture 62 that mates with fastener 58. Threaded fastener 58 operates between clearance aperture 76 and threaded aperture 62 for closing split 60 by drawing together bosses 72, 74, which tightens cylindrical cavity 52 about end portion 18 for securing support arm 16.
FIG. 11 illustrates one alternative embodiment of rod connector 42 of anchor 22 having an alternative tubular female collar 78 forming therein truncated internal cylindrical cavity 52 which bottoms against foot 30. Truncated cylindrical cavity 52 is sized to slip over end portion 18 of the support arm 16. Gripping means 54 is provide by one or more of threaded fasteners 80 or set screws operating through one or more bosses 82 at one or more positions spaced peripherally around tubular female collar 78. Respective internally threaded apertures 84 pierce bosses 82 and adjacent side wall 86 of tubular collar 78. When side wall 86 is sufficiently thick, bosses 82 are optionally eliminated, and threaded apertures 84 pierce side wall 86 directly. One or more of threaded fasteners 58 operating through internally threaded apertures 84 engage end portion 18 of support arm 16 and thereby operate as gripping means 54.
FIG. 12 illustrates another alternative embodiment of rod connector 42 of anchor 22 having an alternative tubular female collar 88 forming therein truncated internal cylindrical cavity 52 which bottoms against foot 30. Truncated cylindrical cavity 52 is sized to slip over end portion 18 of support arm 16. Gripping means 54 is provide by a weld or other fusion joint 90 formed at least intermittently between end portion 18 of support arm 16 and collar 88.
FIG. 13 illustrates another alternative embodiment of rod connector 42 of anchor 22 having an alternative tubular female collar 92 forming therein truncated internal cylindrical cavity 52 which bottoms against foot 30 and is sized to slip over end portion 18 of support arm 16. Gripping means 54 is provide by internal threads 94 provided within cavity 52 and structured to match external threads 96 provided on end portion 18 of support arm 16. Matching internal and external threads 94, 96 cooperate to provide a threaded joint that operates as gripping means 54 between end portion 18 of support arm 16 and female collar 92 of rod connector 42. End portion 18 of support arm 16 is shorter than threads 96 such that a shoulder 98 is provided at a base of threads 96. Shoulder 98 operates as a stop against which a lip 99 of cylindrical cavity 52 is seated when internal threads 94 and external threads 96 are fully engaged.
