Franklin Foss Attorney-John E. Reilly [57] ABSTRACT An adjustable support for positive suspension of articles such as brackets, steps, partition walls and the like comprises an elongated rigid rod having flexible straps or cables of inextensible material wrapped at least partially therearound so as to converge at spaced intervals to define reinforcing areas. The straps at reinforcing areas define suspension locations at which reinforcing clips are retained in vertically spaced positions along the length of the rod. The bracket or other object being suspended from the support includes a downwardly projecting finger insertable vertically into limited space formed between the clips and the outer surface of the rod to positively retain the article in a selected position.

15 Claims, 9 Drawing Figures ADJUSTABLE SUPPORT The present invention generally concerns a supporting device for adjustable and releasable suspension of articles and more specifically concerns a support rod characterized by its relative simplicity of construction and strength and which can be employed singly or in pairs to define verticallyspaced positions along the length thereof at which brackets,'steps, partition walls or the like can be removably suspended.

Various types of supports have been contrived for suspending brackets on which shelving or other items can be retained at selected locations along the length of the support. Typically, the supports take the form of channelled or hollow support bars in which vertically spaced slots have been cut for releasable reception of hooked end portions of brackets. The brackets can then be positioned at selected locations along the length of the bar to support shelving or other items at desired elevations.

The adjustable support of the present invention is suitable for suspending various articles such as partition walls, brackets for shelving or other material and also for suspending steps upon which individuals can stand to use the support as a stilt or pogo stick type of device. The support is therefore useful singly or in combination for both utilitarian and recreational purposes. Basically, the support comprises an elongated rod having high strength straps, ropes, cables or the like of Iongitudinally inextensible material wrapped at least partially therearound defining suspension locations at which desired articles can be' removably suspended.

More specifically, the adjustable support comprises an elongated rod on which straps of high strength material are wrapped at least partially therearound so as to converge at spaced intervals to define reinforcing areas and suspension locations at which metal reinforcing clips are placed in vertically spaced positions along thelength of the rod. In the preferred embodiment described in detail hereinafter, the straps are wrapped spirally around the rod such that the reinforcing areas are defined by the overlapping areas of the straps. The clips are positioned closely adjacent the rod so that the downwardly projecting finger of a bracket or step to be suspended from the support can be inserted between the clip and the support rod and held firmly in place by the high strength straps, ropes, cables or the like.

Accordingly, it is an object of the present invention to provide an adjustable support device which is characterized by its relative simplicity of construction and strength.

It is,another object of the present invention to provide an adjustable support adapted for use singly or in combination for supporting partition walls, shelving brackets and the like or for supporting steps so that the support can be used as a stilt or pogo stick type of recreational device.

It is another object of the present invention to provide an adjustable support having straps, ropes, cables or the like of high strength material wrapped at least partially therearound defining vertically spaced suspension locations for brackets, steps or the like.

It is another object of the present invention to provide an adjustable support device having an elongated support rod with straps of material wrapped spirally in opposite directions around the rod to form overlapping areas in which reinforcing clips are positioned for positive retension of suspended partition walls, brackets, steps or the like.

Other objects, advantages and capabilities of the present invention will become more apparent as the description proceeds taken in conjunction with the accompanying drawings, in-which:

FIG. 1 is a perspective view of an adjustable support of the present invention having a bracket member suspended therefrom;

FIG. 2 is an enlarged side elevation of the support of FIG. 1;

FIG. 3 is a front elevation of the support of FIG. 2;

FIG. 4 is an enlarged section taken along line 4-4 of FIG. 2; 1 1 1 FIG. 5 is an enlarged fragmentary view taken in the direction of the arrows 5-5 of FIG. 2;

FIG. 6 is an enlarged fragmentary section taken along line 6-6 of FIG. 3;

FIG. 7 is a fragmentary view ofa second embodiment of the adjustable support of the present invention;

FIG. 8 is an enlarged section taken along line 8-8 of FIG. 7 and;

FIG. 9 is a fragmentary side elevation of the support shown in FIG. 7 looking in the direction of arrows 9-9 of FIG. 7.

One embodiment 10 of the adjustable support of the present invention is shown in FIG. 1 including a rigid support rod 12, elongated longitudinally inextensible strap means 14 secured to the support rod by upper and

lower attachment collars

16 and 18 respectively and a longitudinally extending brace 20 so as to be appropriately disposed for suspending a bracket type member 7 22 in selected vertically spaced positions.

Looking at FIGS. 2 and 3, it will be seen that the inextensible strap means 14 include two

straps

24 and 26 which have upper ends tucked inside the upper attachment collar 16 and are wrapped spirally in opposite directions around the support rod 12 toward the lower end thereof. The lower ends of the

straps

24 and 26 extend beyond the lower edge of the lower attachment collar 18 and are reversibly folded and passed through a slot28 in the collar 18 so that the lower terminal ends of the straps are disposed inwardly of the collar 18 and can be retained in position by positively securing the collar to the rigid support rod 12. In the disclosed embodiment, both the upper and

lower collars

16 and 18 are screwed to the rod 12 so that the

straps

24 and 26 are prevented from migrating up or down the rod once the collars have been secured in place. To further fix the position of the straps on the support rod and to hold the straps against the rod in tightened flat relationship therewith, the elongated brace 20 is extended up one side of the support rod and is positively attached to each of the attachment collars and to the support rod in spaced locations along the length of the brace to press the straps against the rod so that they are firmly held in place.

In the embodiment 10 of the adjustable support shown in FIGS. 1 through 6, the support rod 12 comprises a tubular member of circular transverse crosssection having a rubber tip 30 on its lower end to reduce the tendency of the lower end to move relative to its supporting surface. The

straps

24 and 26 are flexible and substantially longitudinally inextensible so as to have very little give when tightly wrapped around the support rod. A material which has been found to be very well suited for use as the straps, is nylon webbing of the type used for seat belts in automotive vehicles. It will be appreciated from the drawings, that the two

straps

24 and 26 which are wrapped spirally around the support rod in opposite directions define overlapping areas on opposite sides of the support rod where the straps serve to reinforce each other by doubling their effective thickness. The brace member 20 is positioned on the rod so as to pass over the overlapping areas on one side of the rod and the overlapping areas on the opposite sides of the rod define suspension locations 32 at which the bracket 22 or other member to be suspended from the support can be suspended in a manner to be described hereinafter.

To further reinforce the

straps

24 and 26 at the suspension locations 32, reinforcement clips 34 are positioned between the overlapping straps and the support rod. Preferably, the clips 34, which are best seen in FIG. 4, are metallic clips having a substantially flat central portion 36 lying against the support rod and hooked end portions 38 which extend reversibly along the opposite side of the outermost strap at the particular suspension location. Accordingly, the clips 34 are positively positioned at the suspension locations 32 and are held tightly against the support rod by the inextensible straps.

The bracket or step type member 22 shown in FIGS. 1 through which has been found to be particularly well suited for suspension from the adjustable support includes a flattened support plate 40 supported by a web shaped base 42 including an arcuate back portion 44 at its upper end substantially corresponding in transverse cross-section with the support rod. A depending retention finger 46 secured as by rivets 48 to the back portion 44 of the webbed shaped base 42 is adapted to be inserted between one of the clips and the support rod 12 so that the finger is tightly pinched between the clip and the support rod to positively hold the bracket 22 in a selected position on the support rod. The finger 46 is an elongated relatively thin bar and is preferably arcuate in transverse cross-section to conform with the external surface of the support rod. The retention finger is adapted to extend beneath a major portion of the overlapping area of the straps so that the bracket 22 when properly positioned on the support is positively held in position by the finger. To position the bracket 22 at another suspension location on the support, it is merely necessary to lift the bracket until the retention finger slides out from between the clip and the support rod and slide the bracket along the support rod to the desired suspension location where the finger can be forced between thesupport rod and the clip at the new suspension location.

A second embodiment 50 of the adjustable support is shown in FIGS. 7 through 9, and can be seen to include a support rod 52 of square transverse crosssection with a rubber tip 54 on its lower end serving the same function as the rubber tip 30 on the embodiment described with reference to FIGS. 1 through 6. The embodiment 50 shown in FIGS. 7 through 9 is similar to the embodiment 10 in that two elongated flexible but

inextensible straps

56 and 58 are wrapped spirally in opposite directions around a portion of the length of the support rod 52 and are anchored at their upper ends with an upper collar, not shown, identical to the upper collar 16 described in the first disclosed embodiment and anchored at their lower ends by passage around the outside edges of a channelled vertical brace member 60 having a longitudinal slot 62 near its lower end through which the'ends of the straps are inserted and pinched against the support rod 52 for positive retention by the brace member. The brace 60 is anchored to the upper collar and the support rod at selected locations along its length by screws or other fastening means. Reinforcement clips 64, identical to the clips 34 described in connection with the first embodiment 10, are positioned at overlapped locations 66 along the length of the support rod so that a bracket or step type member 68 can be suspended from the adjustable support at the overlapped locations.

A bracket 68 found suitable for use with this embodiment of the adjustable support is shown on the support including an elongated base portion 70 which has been transversely bent so as to have an included obtuse angle. A central longitudinal portion of the base is partially cut away to define a rectangular opening 72 and a downwardly bent brace portion 74 adapted to rest against the channelled brace 60 overlying the straps. The upper end of the base portion 70 includes an inwardly bent depending retention finger 76 which is adapted to fit tightly between a clip 64 and the support rod 52 when the rod is received in the rectangular opening 72 in the base so that the straight sides of the rectangular opening lie against opposing sides of the support rod to prevent relative rotation between the bracket and the support rod. The retention finger 76 is preferably flat to lie flush with the side of the support rod and be tightly received between a clip and the support rod to positively maintain the position of the bracket. Again, as in the first described embodiment, the position of the bracket on the support rod can be changed merely by lifting the bracket so that the finger slides out from between the clip and the support and positioning the bracket in a similar manner at another of the vertically spaced overlapping locations.

It can be seen from the foregoing description that the adjustable support of the present invention is relatively simple in construction so as to be economical to manufacture and yet provide adequate strength for supporting weights which are relatively large in comparison to the weight of the support. Numerous uses of the support will be readily apparent to those skilled in the art and one of the most readily apparent uses would be as an adjustable support for temporary shelving. More specifically, a plurality of support rods could be provided with spring biased extensions at their upper ends so that the support rods could be positively positioned between the ceiling and floor of a room in which the shelving is to be installed. Elongated planks of shelving material could then be laid upon the brackets at desired elevations along the length of the support rods to forr the shelves. It can be appreciated that more than one bracket could be positioned on a support rod so that a number of vertically spaced shelves could be supported on the same support rods for varied and interesting shelving arrangements. The support rod could also be used in a similar manner to support partition walls having depending fingers adapted to fit snuggly between clips and the support rod at suspension locations.

Another readily apparent use of the adjustable support rod would be as a walking stilt wherein a pair of the supports each having a step type member suspended therefrom at a desired elevation would form effective extensions of a users legs so that he could walk by grasping an upper portion of the support with his hands and moving the support along with his legs in a walking fashion.

A similar use would be as a pogo stick wherein a modification of the step type bracket herein disclosed could be used which would include support plates on either side of the support rod so that a user could position the support rod between his legs with one foot on each of the supporting plates and bounce along by use of a spring biased extension from the bottom end of the support rod. The pogo stick arrangement could be made increasingly or decreasingly difficult by adjusting the elevation of the step type bracket along the length of the support rod.

Other uses of the support device of the present invention will no doubt be apparent to those skilled in the art since the support is of high strength for numerous heavy duty utilitarian uses and is light weight so as to be easily maneuverable and useful as a recreational device such as of the type hereinbefore described.

While the present invention has been described with a certain degree of particularity, it is understood that the present disclosure has been made by way of example and that changes in details of structure may be made without departing from the spirit thereof.
