Figure 1 is a first top perspective view of the present invention shown with the main arm irt a fully extended position. As shown in this figure, d e invemion comprises a non-telescoping frame 1 , a .main arm 2. two pivot arms T and two brace arms 4. The non-telescoping frame preferably comprises a rectangular perimeter frame 5, one or more iorknb pocke <: 6, one or mo e longitudinal skids 7. and a cable tray 8, The purpose of the cable tray $ Is to hold the electric and communications cabling 9. As used herein, the term ''rectangular" also means square.

The embodiment shown in Figure 1 incorporates a power (motor) actuation system. The power actuation, system comprises an electric motor Id with a linear actuator I I . In a preferred embodiment, the inventors used a custom-built linear actuator specifically manufactured by ^'Venture Mfg. Co. (of Dayton. Ohio) for the present invention. The actuator 1 I is used to push the main arm 2 out {i.e. , extend it) ami pull it in. (i.e.. retract it). An alternate embodiment m which a manual actuation system, is used is shown in Figures 27-29.

The non-telescoping frame I fur her comprises two attachment arms 1 2_; which, provide an attachment point ibr the pivot arms 3, as shown in detail in subsequent figures. The two attachments arms 12 are oriented laterally (relative to the non- telescoping frame I k and they are each situated an equal distance inside of the lateral ends of the perimeter (fame 5. The skids 7 are preferably oriented longitudinally (relative to the non-telescoping frame 1 h and they are situated underneath the rectangular perimeter frame 5. The skids ? ate used to transport the structure that is installed on top of the present invention. The tbrkhit pockets 6 are preferably oriented laterally (relative to the non-telescoping frame 1 ), and are situated between the rectangular perimeter fram 5 and the skids 7, Similarly, the attachment arms 12 are preferably situated between t¾.e rectangular perimeter -frame S and the skids ?. The purpose of the fork!ift pockets 6 is to allow a ibrkiitt to lift the frame (and whatever structure is installed upon it).

As used herein, the term 'iateraT or "laterally^" means in the direction indicated with ^'s on Figure 1 , The term "longitudinal" or "longitudinally'^* means in the direction indicated with Y s on Figure L

In a preferred embodiment, die actuator 1 1 extends laterally through the center of the non-telescoping frame 1. The actuator 1 1 is secured on one end (the end opposite the motor 10) to a center bracket 1 7 that is also attached to the main arm 2 and that extends downward from the center of the main arm 2, The cabling 9 is protected by cable tubing 13 that extends laterally between the non-telescoping frame 1 and the main arm 2. The cable tubing 13 extends laterally from the cable tray 8, which can be situated anywhere o«. the non- eleseopi frame 1.

The main arm 2 is paral lel to the longitudinal sides of die perimeter frame 5. The main arm 2 is attached at its center to the center bracket 1 7, On either end of the main arm 2 is a roller wheel 14 (see Figure 2) that travel along (in a lateral direction) die top surface of the pivot arm 3 (which acts as a rail) when the pivot arm 3 is fully extended (as shown in Figures i~9>. The two brace arms 4 maintain the pivot anus 3 at ninety (90)- degree angles to the longitudinal side 5a of the perimeter frame 5. The present invention is not limited to any particular shape of die non-rectangular frame, as long as it has at least one longitudinal side 5a that is straight.

Figure 2 is a second top perspective view of the present invention shown with the main arm in a fully extended position. In this view, the roller wheels 1 are visible. They are not visible in Figure 1 because of the stops 15 on the end of each pivot arm 3. These stops ! 5 extend upward from the pivot arm 15 n the distal-most end of the pivot arm (i.e . the end opposite the end thai attaches to the attachment ami 1.2). The point at which the pivot arm 3 attaches to the attachment a m 12 is a pivot point, as described .more fully below. Figure 3 is a top view of the present invention shown with the main arm in. a fully extended position,

In Figures 4-6, the roller wheels 14 have moved along the pivot arms 3 to the halfway point between the stop 15 on one end of the pivot arm 3 and the end of the pivot arm 3 that is attached to the attachment arm 12 (at the pivot point;. As the roller wheels 14 move along the pivot arms 3 toward the longitudinal side Sa of the perimeter frame 5, the main arm 2 also moves closer (and in parallel to) the longitudinal side 5a of the perimeter frame 5, As this happens, the cable tubing 13 is retracted into the cable tray 8, and the actuator 1 also retracts.

Note that the brace asms 4 are still in the brace position as the main arm 2 retracts (i. e. , moves toward the longitudinal side 5a of the perimeter frame 5), As shown in Figure 5, each pivot arm 3 preferably comprises a V-shaped uuder-suppott 3a that provides added strength and stab lity for the pivot arm 3. As shown in Figure 6, the main amt preferably comprises a saddle bracket 1 6 attached on the in.si.de of the main arm 2 at the center of the main arm 2. The saddle bracket 1 6 is used to install a structure on top of tlie main arm 2 (as shown in Figures 30 and 1),

In Figures 7-9, the roller wheels 14 have moved ail the way along the pivot arms 3 to a point that is nearly, bat not exactly, on top of the pivot point between the pivot arm 3 and the attachment arm 12. At this juncture, the main arm 2 is slightly above and adjacent to ice , j ust outside of) the longitudinal side 5a of the perimeter frame 5, The brace arms 4 may now be removed and stored in a transport position. The brace arms 4 must be removed in order to pivot the pivot arms 3 inward {Le. , toward the main arm 2).

Figure 10 is a perspective view of the brace arm of the present invention. As shown in this figure, the brace arm 4 preferably comprises three extensions— one in the center of the brace arm 4a anrl one on either end of the brace arm. 4b, 4c. Although these extensions are shown in the figures as downwardly extending, they could also be upwardly extending. Figure iOA s a detail perspective view of the brace m m a brace position. As shown in this figure, when the brace arm 4 is n a brace position, the extension a on one end of th brace arrn 4 is positioned inside of a receptacle 19 on the inside of the pivot arm 3., roughly in the center of the pivot arm 3. The extension 4b on the other end of the brace arm 4 is positioned inside of a receptacle 19 on the outside edge of the longitudinal side 5a of the perimeter frame 5. The extension 4a in the center of the brace arrn 4 is not used in this position.

Figure 10.8 is a detail perspective view of the brace arm removed from the brace position. As shown in this figure, to remove the brace arm 4, simply hit the two end extensions 4 b, 4c out of the receptacles 19 and lift the brace arm 4 upward.

Figure I OC is a detail perspective view of the brace arm in a transport position. In this position, the center extension 4a is placed into the same receptacle 1 9 that housed the end extension 4c when the brace arm 4 was in a brace position, in the transport position, the brace arm 4 is stowed up against the lon.gitud.hial side 5a of the perimeter frame 5.

Figure 1 .1 is a top perspective view of the present invention with the pivot arms at a forty-five (45)-degree angle relative to the main arm. Once the brace arms 4 have been stowed in the transport position, the pivot amis 3 can be rotated (or pivoted) toward the main arm 2. As noted above, the point at which the pivot arm 3 connects to the attachment arm 1 2 is a pivot point. This pivot point is shown in detail in Figures 18-26 and 3-34. As the pivot arm 3 is rotated inward (toward the main arm 2) at the pivot point on the attachment arm 12. the roller wheel. 1.4. which sits on top of the pivot arm 3 on the end closest to the attachment arm 12, also pivots. Specifically, the roller wheel, bracket 14a comprises an upwardly extending pin 14b that is inserted into a hole 2a on either end of the mam arm 2 (see Figure 35); this pin 14b rotates within the hole 2a (and the sleeve 23 above the hole 2a) so that the roller wheel 14 can tarn with the pivot arm 3 but rotate relative to the main arm 2. Figure 1 2 is a top view of the present invention with the pivot arms at a forty-five ( 5) -degree angle relative to the main arm.

Figures 1.3 and 14 show the pivot arms in a fully retracted position: that is, each pivot arm 3 has been fully rotated (at the pivot point on the attachment arm 12} so that the pivot arms 3 now lie directly underneath the main ami 2. Both the main arm 2 and the pivot arms 3 arc now parallel with the longitudinal side 5a of the perimeter frame 5. Figure 15 is a detail perspective view of the pivot arms stowed on the center bracket of the m in arm. As shown in. this figure, when the pivot rms 3 are in a fully retracted or stowed position, the distal ends of the pivot arms 3 are placed on top of supporting brackets 17a that extend laterally from the center bracket 17. A pin or bolt 18 is then inserted through a hole in the distal end of the pivot arm 3 and also through the supporting bracket 17a to hold the pivot arm 3 in plane.

Figure 1.6 is a perspective vie of ihe pivot arm of the present invention. As noted above, the distal end of each pivot arm 3 preferably comprises an upwardly extending stop 15 that prevents the toiler wheel 18 from tra veling off the distal end of the pivot arm 3. This figure also shows the V-shaped under-support 3a and receptacle 19 mentioned above. The proximal end of the pivot arm preferably comprises a downwardly extending threaded bolt 20 and nut 2L which surrounds the bolt 20, This boll 20 is fixedly attached to the proximal end of the pivot arm 3 (see Figures 1 -23 and. 25-26), and it extends into a sleeve 22 in the attachment ami 12 (see Figures 33 and 34). The nut 21 can be raised or lowered on the bolt 20 to raise or lower the vertical position of the pivot arm 3 relative to the attachment arm 5.

Figure 1 7 is a perspective view of the roller wheel and roller wheel bracket of the present invention. As shown in Figure. 35, the upwardly extending pin 1 b is inserted into a hole 2a on the underside of the end of the main arm 2 and is allowed to rotate freely within a sleeve 23 located just shove the hole 2a. As shown in this figure, the roller wheel 14 rotates about an axle 14e that is secured to the rol ler wheel bracket 14a with a nut 21 ,

Figure 18 is a detail side view of the pi vot point between the attachment arm and the pivot arm shown with the pivot arm fully extended, and Figure 19 is a section view of the pivot point shown in Figure 18 (taken at A- ). As shown In Figure 18, the pivot point at the top of the roller wheel 14 (i.e. , the upwardly extending pin 14b) is offset vertically from the pivot point at the boh 20 between the attachment a m 12 and the pivot arm 3.

Figure 20 is a detail side view of the pivot point between the attachment arm and the pivot arm shown with the pivot arm at a forty- five (45)-degree angle relative to the main arm. and Figure 21 Is a section view of the pi ot point shown in Figure 20 (taken at B--B), At this stage, the upwardly extending pin 14b is nearly vertically aligned with the holt 20,

Figure 22 is a detail side view of the pivot point between the attachment m and the pivot arm shown with the pivot arm fully retracted/stowed, an4 Figure 23 is a section view of the pivot point shown in Figure 22 (taken at C-C). At this stage, the upwardly extending pin 14b is vertically aligned with the bolt 20. Thus, as the distal nd of the pivot arm 3 is rotated inward (toward the center bracket 17), the upper ana lower pivot points align (that is, the upwardly extending pin 1 b and the bolt 20), and the .main arm 2 is tightened up against the longitudinal side 5 a of the perimeter frame 5.

In the Latter embodiments (that is, with the manual actuation system), the motor 10 and actuator 1 1 shown in Fi u s 36-41 are replaced with a lateral tube 24 and a lateral rectangular conduit 25, as shown in Figures 27-29.

Figure 42-49 illustrate a series of alternate embodiments in which there is no rectangular perimeter frame, instead, there is a longitudinal surface 26 in lieu of the longitudinal side 5a of the rectangular perimeter frame 5. ( Note that the longitudinal surface may be flat or curved, beveled, rounded, etc.: the only criterion is that the attachment arms 12 must be able to attach to it) These embodiments shown with varying numbers of pivot amis and actuators— may be used where there is an existing frame (for example, on a semi-trailer) to which the longitudinal surface 26 is secured (as in bolted, welded, etc.). Note that the attachment arms 12 are considerably shorter than in the previously described embodiments (with the rectangular perimeter frame). The invention operates in ail respects as described above in connection with the preceding embodiments.
