It is to be noted that the degree and speed of extension/retraction of some examples of the pneumatically controlled and hydraulically controlled telescoping modules disclosed herein may be manually controlled by an operator, or alternatively with a control box 25 which communicates via a controls conduit 20 with an extension/retraction mechanism contained within an extension-tube housing. It is to be noted that some examples of electrically controlled telescoping modules disclosed herein may be manually controlled by an operator, or alternatively, with a control box 25 which communicates via a controls conduit 20 with an extension/retraction mechanism contained within an extension-tube housing, or alternatively for example, by wireless transmission of signals from a remote control box to a receiver on the telescoping module that is in electrical combination with the extension/retraction mechanism.

The telescoping modules disclosed herein can be combined with a variety of modules disclosed in International Application No. PCT/CA2017/050376 to quickly configure useful and sturdy utility assemblies on a job site or an office site or an industrial site or a retail site or in a home environment.

To gain a better understanding of the embodiments disclosed herein, the following examples of utility system assemblies and support structure assemblies are described. EXAMPLES

Example 1 : Height-adjustable utility cart assembly

An example of a rolling height-adjustable utility cart assembly that may be quickly assembled by incorporating the telescoping modules with certain other modules of the system, as disclosed herein and in International Application No. PCT/CA2017/050376, is shown in Figs. 9 and 10 (lowered and raised positions, respectively). The utility cart assembly 350 provides a lower open tray assembly and an upper box tray assembly for transporting equipment, properties, materials, supplies, and the like around a worksite or other location, movable by pushing or pulling the utility cart in any direction on the four 360° pivotable caster wheel modules 400. Alternatively, in place of wheel modules, similar assemblies may be configured with other modules of the system at its base for standing shelf and storage assemblies, such as foot modules "580", "585", "590" or end-cap components "680" shown in Figs. 24, 25, and 33 of International Application No. PCT/CA2017/050376. In this example, four telescoping modules with female ends 5 form the height-adjustable frame of the utility cart assembly 350. Secured from these corner telescoping modules 5 are two tray assemblies, each having a first example of a tray bottom 355 with corner openings 360 at all four corners wherein the four telescoping modules 5 can be aligned and therein secured by collars 370. As illustrated in Fig. 9, each telescoping module 5 is first engaged with two collars 370 by screws 375 into side-mount bores, and screws 375 with T-nuts 380 into the nut / conduit channels, where they are secured on the lengths of the telescoping modules 5 just below each desired tray bottom mounting position. From under the tray bottoms 355 and into the openings 360, the modules 5 with collars 370 can be inserted and there secured to the tray bottoms 355 by screws 375 passed through collar screw holes 365 for threadable engagement with threaded bores in the top-faces of the collars 370.

As shown with the upper tray assembly, up to four side panels 385, 388 can be secured by screws 375 threadably engaged with side-panel screw holes 395 in the side edges of the tray bottom 355 and in the sides of the collars 370 thereto attached. For added stability of the side panels 385, 388, an additional set of four collars 370 can be secured to the telescoping modules 5 where the bores in the top corners of the side panels align and screws 375 can be threadably engaged with bores in the sides of the collars 370 thereby providing additional reinforcement of the tray assembly.

In each of the four corners of the utility cart assembly 350, a caster wheel module 400 is demountably engaged by its male member flat-mount assembly 85 within the bottom end receptacle of each telescoping module 5, to allow for rolling movement of the utility cart assembly. In this example, the castor wheel module 400 comprises a male member flat-mount assembly 85 secured to the top-face of a mount component 405. The male memberflat-mount assembly 85 is first aligned against the top-face of the mount component 405 by pegs 252 on the bottom of the flat-mount pivot-lock sprocket (visible in Fig. 6) inserted into peg holes 410 in the top-face of the mount component 405 where, with a bolt passed through the center of the three components and threadably engaged with the center threaded bore 415 or threaded insert located at the center of the mount component 405, the male member flat-mount assembly 85 is demountably secured. A castor wheel 420 is rotationally engaged with the mount component 405 by mount screw or other means of attachment with the underside of the mount component 405.

In this example, the height of the upper tray assembly can be raised or lowered on the telescoping modules 5 which are extendible and retractable by operations of the control box 25 transmitted to the telescoping modules via their controls conduit 20.

It is to be noted that, if so desired, one or more additional tray assemblies may be included in the utility cart assembly 350 below the upper tray assembly on the lengths of the telescoping modules 5 above the extension-tube end guides 30, or above the telescoping modules 5 on additional lengths of extension-tube housing modules (not shown) as disclosed in International Application No. PCT/CA2017/050376, having male ends to be secured within the four upper receptacles 40. When an additional tray assembly is to be located on additional modules above the upper tray bottom 355 and the user wishes to controllably change the separation of the adjacent tray bottoms, a set of four telescoping modules 200 or 280 may be incorporated into the assembly at the available receptacles 40. In this case, the extension/retraction of each set of four telescoping modules 200 or 280 would be separately controllable with a separate control box for each set of modules.

Example 2: Height-adjustable work station assembly

An example of a height-adjustable work station assembly 450 that may be quickly assembled by incorporating the telescoping modules with certain other modules of the system, as disclosed herein and in International Application No. PCT/CA2017/050376, is shown in Figs. 1 1 and 12 (lowered and raised positions, respectively).

This example comprises a rectangular desk top 455, and a rectangular shelf 460 situated above the desk top 455. Mounting plate recesses 470 are provided in the top surface of the desk top 455, wherein two circular mounting plates 475 may be secured by plate screws 480 through screw bores 478 or other means of attachment with the surface of the desk top 455. Additionally, two circular mounting plates 475 are secured within two mounting plate recesses (not shown) in the bottom surface of the shelf 460. Each of four male member flat-mount assemblies 85 is securely engaged with a mounting plate 475 by a bolt threadably engaged with the center threaded bore 477 in each mounting plate 475. The lower ends of two of a first example of a double-receptacle side-opening module 465 each comprising a fifth example of an extension-tube housing 466 with a tube bore 467 and side-mount bores 468, are then engaged with the upward-extending male member flat-mount assemblies 85 secured to the top surface of the desk top 455, and secured in place by bolts 120 passed through tube bores 467 and the male components therein for threadable engagement with threaded bores or threaded inserts (not shown) in the proximal sides of the side-opening receptacle covers 135. Likewise, the upper ends of the double-receptacle side-opening modules 465 are engaged with the downward-extending male member flat-mount assemblies 85 secured to the bottom of the shelf 460, and secured in place by bolts 120 threadably engaged with side-opening receptacle covers 135.

It should be noted that a mounting plate may be circular or oblong or triangular or square or rectangular or trapezoidal or hexagonal or octagonal in shape and may provide varying numbers of screw bores 478 or other means of attachment with a surface. The bottom surface of the desk top 455 is provided with four triangular mounting plate recesses (not shown) near each of the corners of the desk top 455. Each recess is configured to receive therein a triangular mounting plate 485 secured to the bottom surface of the desk top 455 by plate screws 480 through bores, or other means of attachment. Four male member flat- mount assemblies 85 are each securely engaged with a triangular mounting plate 485 by a bolt threadably engaged with the center threaded bore in each mounting plate. Four of the telescoping modules with a female end and a male end 280 may each be securely mounted thereon a male member flat-mount assembly 85 by bolts 120 and side-opening receptacle covers 135, providing thereby the height- adjustable leg components of the work station assembly 450. The bottom male member flat-mount assemblies 85 of the telescoping modules 280 are, in this example, removed and replaced by four end-caps 490 secured to the modules' extender male end adapters 270 by screws 492, thereby providing foot components. In this example, the height of the desk top surface can be raised or lowered on the telescoping modules 280 which are extendible and retractable by operations of the control box 25 transmitted to the telescoping modules via their controls conduit 20. Similarly, rolling work station assemblies may be configured by including caster wheel modules 400, for example, in place of end-caps 490 or other foot modules, in assemblies wherein telescoping modules with receptacles or additional modules with receptacles are provided at the bottom ends.

Where a larger shelf or two smaller shelves are provided in similar assemblies, two additional mounting plate recesses 470 are provided in the back corners of the desk top 455 for attachment of the circular mounting plates 475 and male member flat-mount assemblies 85, and additional modules thereon. When not in use, a recess 470, for aesthetic purposes, may have inserted a desk top recess cap 495 provided for closure of the recess. It is to be noted that the desk tops or table tops or shelves or staging of similar assemblies may be square, rectangular, trapezoidal, triangular, pentagonal, hexagonal, heptagonal, octagonal, decagonal, circular, kidney-bean shaped, wave-shaped, and may have other forms of symmetrical and asymmetrical curvilinear shapes. Although it will be most common that these modular assemblies are provided with four legs, it is optional to provide three legs for a triangular top surface, for example, or two A-frame legs on two sides of a top surface, or a single weighted or broadly footed center leg, to assemble a variety of modular configurations.

Example 3: Height-adjustable platform assembly An example of a height-adjustable platform assembly 500 that may be quickly assembled by incorporating the telescoping modules with certain other modules of the system, as disclosed herein and in International Application No. PCT/CA2017/050376, is shown in Figs. 13, 14, and 15 (lowered, raised, and raised exploded views, respectively). This example comprises a rectangular platform 505 mounted to the receptacles 40 in the upper ends of six telescoping modules with female ends 5, by male end assemblies 85 and mounting plates 475, 485 as described above in reference to Example 2. To add strength and rigidity to the platform 505, platform stiffeners 510 may be inserted and fastened into corresponding recesses in the underside of the platform using screws and/or adhesive and/or other means of attachment.

A second example of a tray bottom 515 and third and fourth examples of side panels 540 and 545 are secured to pairs of collars 370 at the lower ends of the raise-able extension-tube housing sections of the six telescoping modules 5 thereby secured within corner openings 525 and middle openings 530 along the outer periphery of the tray bottom 515 using screws passed through collar screw holes 535 and threadably engaged with threaded bores in the top sides of the corresponding collars 370, as described above in reference to Example 1 . A third example of a tray bottom 520 is shown mounted by the same means as above to collars 370 secured to the bottom section extender female ends of the six telescoping modules 5.

To increase the strength and rigidity of the overall assembly, bracing modules may also be incorporated into the assembly as illustrated or in other similar arrangements. In this example, the sets of three telescoping modules 5 which form the two short sides of the assembly are reinforced by four of a second example of a double-receptacle side-opening module 555, each demountably engaged with two of an example of a male member side-mount assembly 560 having the same male component 90 and wide pivot component 100 as previously described but wherein the flat-mount pivot-lock sprocket 105 is replaced with a concave pivot-lock sprocket 565 allowing for the male assembly 560 to be mounted to the cylindrical side of an extension-tube housing module using a bolt or screw threadably engaged with a T-nut securely held within the nut / conduit channels of the extension-tube housing, or optionally, a threaded insert corresponding with a side-mount bore. For further reinforcement, frame corner braces 570 are fastened by screws 575 engaged with T-nuts 380 held in the nut / conduit channels of the intersecting side-opening modules 555 and telescoping modules 5.

For an even greater structural integrity of the platform assembly 500, the long sides of the assembly are reinforced by two of a third example of double- receptacle side-opening module 580 demountably engaged to each of the corner telescoping modules 5 at a male member flat-mount assembly 85 affixed to the telescoping modules 5 by a sub-assembly of components comprising an example of a multi-angle male member mount bracket 585 engaged using bolts 120 with an example of plate wedges 590 having fastened by screws 575 thereon a bracket mount plate 595 and male mount spacer plate 600 whereon the male assemblies 85 are provided. Optionally, as illustrated, diagonal bracing may also be provided, in this assembly 500 using four of a fourth example of double-receptacle side- opening module 605 each supported by two of an example of a 45° offset side- mount male bracket 610 each with a demountably engaged flat-mount male assembly 85 and secured to corresponding nut / conduit channels by screws 575 and T-nuts 380.

In each of the four corners of the platform assembly 500, a caster wheel module 400 is demountably engaged by its male member flat-mount assembly 85 within the bottom end receptacle of each telescoping module 5 to allow for rolling movement of the platform assembly 500. Similar static assemblies may be also configured by including end-caps 490, for example, or other foot modules, in place of wheel modules in assemblies where telescoping modules with extender male end adapters 270 or additional modules with male flat-mount end plates 225 are provided at the bottom ends.

In this example, the height of the platform and middle tray bottom 515 can be raised or lowered on the telescoping modules 5 which are extendible and retractable by operations of the control box 25 transmitted to the telescoping modules via their controls conduit 20. Similar assemblies as Example 3 may be configured also for height-adjustable bedframe systems and the like. NUMBERING KEY
