This invention has to do with an adjustable expansive and extensible unit composed of a plurality of sections which permits the adding, attaching and detaching of additional sections or members in both adjustable and stationary positions.

This plurality of sections and/or attaching members or sections is adapted to be assembled, adjusted and/or regulated in such a manner as to provide a non-collapsible and extremely endurable and strong support for any article or object suspended or supported therefrom or thereon.

This plurality of sections or members is constructed in such a manner that they are adapted to be assembled and adjusted at will and may be extended in any direction and are adapted to permit cross members to and/or suspended therefrom, while permitting both the main sections or members and cross members to extend in any desired directions or positions.

Another feature of my invention is that all end sections are designed to hold and are equipped with an adjustable detachable and expansive attachment means which permits either the end sections by themselves or together in the assembly unit to be fastened, adjusted (swinging or otherwise) expanded or secured at any desired angle, position or direction.

Moreover, my unit is so constructed as to enable it to be adjustably and instantly installed or attached to any of the ordinary supports, such as closet hooks or other hooks, nails and equivalent and/or independent supporting means, thus eliminating and obviating the necessity of any labor, such as nailing, screwing, or hammering during the course of installation of the unit. It is equally simple, easy and instantly detached.

My invention is simple and strong of construction and can be manufactured at an extremely low cost, thereby permitting the merchandising of the item at the minimum retail price. Among other advantages the unit is constructed so that it will not sag, bend or rattle when installed and/or adjusted and is adapted to hold or suspend practieally any weight that the independent wall or other outside supports will bear. My invention readily lends itself and is adaptable to be manufactured in any size or thickness.

As illustrated in these drawings, my extension unit consists of a plurality of telescopic sections. When composed of three sections, as shown in Figs. 1 to 4 inclusive, my supporting unit has a center section 20 and a pair of end sections 21 and 22. The end sections are duplicates of each other and the center section telescopes into the end sections.

This arrangement may, however, be reversed and the center section be made to'telescope over the end sections rather than into the same. as actually shown in these drawings.

The several sections may likewise be variously designed to permit and hold the telescopic adjust- 6| ment. As here shown, the several sections are formed as hollow members of generally oblong cross-section. So formed they present each a pair of spaced parallel front and rear walls 23 holding the adjustment or locking means of the a to the desired new position,

telescopic center section 20. These means may be of any desired character.

As here shown' they are simple wing bolts 21 and 28 fixed vertically through the end sections. The'heads of the wing bolts are substantially flush with the upper walls of the end sections, and have a square shoulder extending below their heads so as to prevent the bolts from rotating inside the members while the wing nuts are being tightened. The wing bolts may be: varied in construction to suit our particular needs. The wing nuts 29 and 30 of the wing bolts are positioned beneath the bottom walls of said end sections. For example, so positions" they are out of the way of the garment hangers, one of which is shown in dotted lines at H in Fig. 1, and hence do not interfere with the free adjustment of the hangers H longitudinally along the end sections or the center section. My invention, however, is not limited to the supporting of hangers, garments or the like, but may be used for the support or reinforcement of anything.

The wing bolts are received in and slide freely along registering longitudinal slots 3| and 32, formed respectively in the topand bottom walls of the center section 20. These slots terminate short of the ends of the center section itself leaving at such ends unslotted wall portions or webs 33, 33' and 34, 34' at both the top and bottom edges of the center sections. These webs function as limiting stops against which the wing bolts 21 and 28 contact to prevent accidental disassembly of any of the several sections.

When deliberately disassembling the several sections, it is only necessary to unscrew the wing nuts of the wing bolts and remove the bolts from said slots 3| and 32. When the wing bolts are positioned within the slots, the adjustment of the several sections relative to one another is held by tightening the wing nuts against the bottom walls of the end sections. This clamps the sections firmly and reliably, and enables the adjustment to be changed instantly by, simply loosening up on the wing nuts, sliding the sections and re-tightening said nuts. My invention is not limited in the use of wing nuts or wing bolts but will function just as reliably with the use of any equivalents thereto.

Adjacent their outer ends the end sections are provided with means adapted for quick detachable engagement with any suitable supporting devices, as the conventional hooks 35 found in any closet or other enclosed space.

As here shown such quick-detachable suspension means are themselves hooks 36 or their equivalents. These'hooks 36 are set vertically through the end sections, Figs. 8 and 12, comprise each a threaded portion and as detailed in 31 on which is threaded a wing nut or its equivalent-38 and a hooked end portion 39.

The threaded portion 31 is set through the bottom wall of each end section and the wing nut 38 threads on said threaded portion and 5 clamps against said bottom wall. By'loosening said nut and rotating the hook about its own axis, its hooked end portion 39 may be swung to various positions and again clamped. "This enables the supporting unit to be suspended from 10 the hooks 35 or their equivalent supporting devices regardless of the position of said devices 35, and locked in such adjusted position by tighten- .ing up on the wing nut.

The hooks 36 are also adjustable vertically in 15 their bearings in the end sections so as to be engageable with suspension devices 35 positioned at different heights. In order to permit this action, the hook 36 is provided just above the top wall of the end section with a thin rounded portion 20 or key 40. This normally rests on the top wall of the end section at right angles to the similarly shaped hole 4| therein through which the hook passes. If the hook is to be lowered, the wing nut 38 is first loosened, the hook rotated through 25 a quarter revolution to align thethin part of the key 40 with the hole 4| and the hook lowered through said hole to the desired level and locked by tightening up on the wing nut 38.

In order to provide a fixed or stationary bearing at the ends of the supporting unit, the end sections 2| and 22 are desirably provided with wall engaging bearing elements 42 adapted to rest flatly against a wall or other supporting surface W. (See Figs. 1 and 2.)

These may be conveniently formed as oppositely extending flanges which are bent outwardly at right angles from the front and rear walls of the end sections 2| and 22, and are adapted to be screwed or otherwise fastened as at 42 to 40 the wall or other support W.

While desirable, such bearing flanges 42 are not essential and may be omitted where not needed without affecting the efficiency of the supporting unit, or they may be made and formed 45 from any angles from the front and rear walls of the end section 2| and 22.

In the form of my invention illustrated in Fig. 5 and the figures based thereon I provide for unlimited extensibility of the supporting unit 50 while at the same time providing that strength and rigidity against collapsing, sagging or buckling so essential in a multi-section extension unit of this class.

The unit of Fig. 5 is a multi-section unit which 55 may be indefinitely expanded as to length by the addition of detachable and interchangeable members or sections, these being reinforced and strengthened against collapse by means of novel reinforcement or coupling members so that the 60 ultimate unit in whatever length to which it has been expanded is strong and rigid at all points along its extent.

For convenience of illustration I have shown in Fig. 5 a four-section supporting unit equipped 55 with only one reinforcement member. It will be understood however that this showing is only illustrative and that units of far greater length may be built up by simply adding on extra members or sections and extra reinforcement cou- 7 pling or collar members.

As shown in Fig. 5 the unit consists of two end sections 44 and 45 corresponding to the end sections 2| and 22 of Fig. 1, two intermediate sections 46 and 41 corresponding generally to the 7 aoaasai intermediate section to of Fig. l and a central reinforcement member, coupling or collar is.

The end sections 64 and 45 are provided at their outer ends with hooks or equivalent suspension elements similar to the hooks 36 of Figs. 1 and 2. The intermediate sections 45 and M are slotted at top and bottom similarly to the intermediate section ill of Figs. 1 and 2, and the sections 44 and d5 are adjustably assembled with the sections 43 and M respectively by means of wing bolts similar to the wing bolts 21 and 28, which, incidentally, may have squared portions 49 below their heads (see Figs. and 13) which fit within the longitudinal slots 3| and 32 of sections 46 and 47 and/or any other similar slotted sections and prevent accidental rotation of the bolts therein.

The inner ends of the sections 46 and 41 are received within the tubular reinforcement collar 48, being held therein by means of other wing bolts '50 and 5| similar to the bolts 21 and 28, the collar adjacent either end being apertured as at 52 and 53 (Figs. 6 and 7) to fixedly receive said bolts, and the heads of the bolts being received in the slots 3| and 32 of the sections 45 and 41. Both inner ends of 46 and 41 abut firmly up against each other when reinforced and locked by collar 48, which positively prevents any movement in any direction of any or either 46, 41 or 48 even if wing nuts are not screwed up tightly. When reinforced or locked in position with the collar abutment stop 33-33 in Fig. 3 positively prevent outward inward or any movement relative only thereto. Thus longitudinal adjustment of the individual sections 44 and 45 and 45 and 41 relative to each other and to the reinforcement collar or sleeve 48 is permitted and held by means of the individual wing bolts 21 and 28 and 50 and 5|, the reinforcement member 48 strengthening and stifiening the unit against collapse, sagging or bending in any and all positions of adjustment.

In Fig. and the figures based thereon, I have shown a further adaptation of my invention particularly designed to provide extensibility in several directions as well as a highly desirable flexibility and universality of attachment or positioning.

In said Fig. 15, the unit designated generally by the reference character L may be considered as a lengthwise span for a closet or other enclosure C and the units designated generally by the reference characters T and T' may be considered as cross or transverse supports.

The sections constituting both the lengthwise and the cross-wise spans may be considered as the same or equivalent to theend sections 2| and 22 and the center section of the unit shown in Fig. l, the several sections of these several units L and T and T being interchangeably usable. For convenience of description, however, the sections of the span L are designated as 54, 55, and 56; those of the cross span 'I' as 51, 58 and 59; and those of the cross span T as 60, GI and 62.

The sections 58 and GI are formed for quick detachable interlock with the sections 55 and 56, respectively, of the span L, the sections 58 and 6! being cut out or equivalently machined as indicated at 63 in Figs. 14 and 16 to interlock or attach with the sections 55 and 56, and being fastened in such interlocking relation by means of the wing bolts or equivalent fastenings 54 or 65.

In some instances where desired, the assembly of supporting units shown in Fig. 15 or any of the individual units or members may be provided with means for suspending it in a pivotal mannor from any fixed support, as the screw eyes 56. when so constructed, the end sections of any or all of the units carry swivel attachment devices 5? (see Fig. 17). By means of said swivels 5! the units may be suspended from eyes 53 which 5 do not happen to exactly aline with the units, as indicated in full and dotted lines in Fig. 17.

A still further variant of the attachment hook or its equivalent is illustrated in Fig. 18, wherein the hook is generally similar in type and method 10 of clamping as that illustrated in Figs. 8 and 12, but is especially designed to enable the supporting unit to be positioned in offset relation to a fixed suspension hook or equivalent supporting device. In the embodiment of Fig. 18 the shank 15 of the hook 33 above the rod section II is bent upon itself at right angles and extends laterally of the rod section as an arm portion 63. This is bent upwardly and over upon itself to form the hook proper 39. Thus the hook portion 33 20 is offset with respect to the shank 36. By rotating the hook in its bearing in the section 2| the hook portion 39 may be adjusted relative to the section 2| and to any fixed suspension hook or equivalent supporting device.

Either the attachment means of Fig. 17 orof Fig. 18 maybe used with the assembly of Fig. 15, or the span units shown in Fig. 15 may be equipped some with the devices of Fig. 17 and some with those of Fig. 18. so

Similarly as to the arrangement of span units shown in Fig. 15, these may be arranged in various combinations. They may extend at any angle and in any direction. There may be any number of them and they may be composed of any desired number of individual members or sections.
