  • the first endcap 12 has an endcap shaft 22 that is pivotably attachable to a rigid support mount (not shown) , such 0 as an orifice sized to accept the endcap shaft 22 or a track configured and sized to engage the grooves on endcap shaft 22.
  • the first endcap 12 is pivotably coupled via pins 24 to both the upper channel 14 and the lower channel 16.
  • the opposite ends of the upper channel 14 and the lower channel 16 are 5 pivotably coupled via pins 24 to the second endcap 18.
  • the second endcap 18 is coupled to the forearm extension 20 via a forearm extension pin 92.
  • the forearm extension 20 has a vertically disposed hole 26 therethrough for accepting a device mount (not shown) such as a tilter, platform or other apparatus .
  • the combination of the upper and the lower channels 14, 16 and the first and the second endcaps 12, 18 form an adjustable parallelogram that permits a device coupled to the forearm extension 20 to be raised and lowered to a desirable height.
  • the parallelogram retains its position by employing a gas spring 28, which is pivotably and adjustably attached to the first endcap 12 and the upper channel 14, as will be further described below.
  • the gas spring 28 is sized so as to have a fixed length until an upward or downward force is exerted at the second endcap 18 that exceeds the gas spring' s designed resistance.
  • the gas spring 28 causes the parallelogram to retain its position when the only force exerted at the second endcap 18 is the weight of the device, but permits the parallelogram to be adjusted when a user pushes the device coupled to the forearm extension 20 up or down.
  • Fig. 2 illustrates a side view of the first endcap 12, having the endcap shaft 22 disposed on a first end 30 of the first endcap 12.

  • the second end 42 of the threaded rod 38 is configured to be engaged by a hex-shaped key which is inserted through the hole 36 when the second end 42 is properly aligned with the hole 36.
  • the hex-shaped key is employed so as to rotate the threaded rod 38 along its axis of rotation.
  • the clevis 48 moves along the length of the threaded rod 38 in a direction that corresponds to the direction which the hex-shaped key is turned. This movement of the clevis 48 permits the gas spring 28 to be adjusted.
  • Figs. 4(a) and 4(b) illustrate the upper channel 14, which comprises channel bottom 60 from which extend two channel sidewalls 62.
  • the channel bottom 60 and the sidewalls 62 are typically stamped from 13 gauge steel sheet in order to give the upper channel 14 a desired degree of structural rigidity.

  • Figs. 5(a) and 5(b) illustrate the lower channel 16 which comprises a channel bottom 78 from which extend two channel sidewalls 80.
  • the channel bottom 78 and the sidewalls 80 are typically stamped from 13 gauge steel sheet, which is relatively heavy in order to give the lower channel 16 a desired degree of structural rigidity.

  • Fig. 6 illustrates the second endcap 18. Unlike the first endcap 12, the second endcap 18 does not have an endcap shaft, nor does it have a clevis assembly for attachment to the gas spring 28. Instead, the second endcap 18 has a hole 90 disposed in a bottom end for receiving the forearm extension pin 92, and a hole 94 in a side for inserting a pin 96 into the forearm extension pin 92, as illustrated in Fig. 1.

  • the shaft 114 is integrally molded with the endcaps 102, 108 by employing interlocking mold technology. Interlocking molds permit a near-perfect mold to be made, minimizing the machining that is required to insure that the shaft 114 is not out-of-round. By minimizing the amount of machining that is required to be performed on the shaft 114, the use of interlocking molds insures that the strength of the casting, which is primarily located in the skin of the cast, is maximized.
  • each of the endcaps 102, 108 is reduced significantly. That is, the cost of the steel shaft 22 and the manufacturing required to separately machine and then insert the steel shaft 22 into the aluminum cast mold of the prior art is reduced.

  • the co- planar faces of the shelves 162 are configured to engage a retainer clip 126, which is fastened in place by, for example, a pair of screws 128.
  • the groove 164 defines a spacing for accepting one end of a threaded rod 124, as discussed in more detail below.
  • the first endcap 102 and the second endcap 108 are identical at this point. That is, unlike the prior art endcaps 12, 18 which are different from each other, the endcaps 102, 108 are advantageously manufactured the same way. Thus, the cost of manufacturing two different kinds of endcaps are eliminated.

  • the screws 46 which are employed to the fasten clip 44 inside the first endcap 12 are difficult to access due to their position underneath the threaded rod 38, thus complicating the process of aligning the second end 42 with the hole 36.
  • the fastening of- the clip 44 inside the first endcap 12 is also rendered more difficult because the clevis 48 is already attached to the gas spring 28.

  • the pin 96 is not required to hold the forearm extension pin 92 within the second endcap 18.
  • the current invention uses the shaft 114 of the second endcap 108 to connect the second endcap 108 to the forearm extension 110.

  • the upper channel 104 has numerous manufacturing advantages over the upper channel 14 of the prior art, and others like it. For instance, with reference to the upper channel 14 of the prior art shown in Figs. 4a-b, the welding which is required to attach the rollers 66 to the upper channel 14 is difficult to perform.
  • the axial centerlines of the rollers 66 must be near-perfectly parallel to each other, while being near-perfectly perpendicular to the longitudinal centerline 76 of the channel bottom 60.

  • the rollers 66 due to the hardness of the steel employed for the prior art upper channel 14, the rollers 66 must be MIG welded thereto, which in turn requires the rollers 66 to be fabricated from expensive cold-rolled steel. Although it is plausible for a manufacturer of the rollers 66 to employ a cheaper material, such as leadloy, these cheaper materials do not provide a safe and consistent weld when joined to the steel upper channel 14. Typically, tests must be performed on the roller material to insure that leadloy has not been supplied. By contrast, the upper channel 104 of the present invention requires no welding, eliminating the cost of aligning the rollers, the cost of performing the welding and the cost of testing the rollers to determine if they are a suitable welding material.
  • An additional disadvantage of welding the rollers 66 to the upper channel 14 is that the heat produced by welding the rollers 66 to the upper channel 14 may cause the upper channel 14 to curl or deform. If this occurs, alignment of the rollers 66 is ruined and the upper channel 14 is rendered useless, requiring it to be discarded. By eliminating any welding required during the manufacture of the upper channel 104, the likelihood of heat-deforming the upper channel 104 is also eliminated and materials are not wasted.
  • the prior art upper channel 14 is made of steel, which means that the upper channel 14 is formed by heating a piece of steel and bending the steel to form the channel bottom 60 and the sidewalls 62. Thus, precise manufacturing is required to ensure the sidewalls 62 extend up from the channel bottom 60 at 90 degree angles.
  • the upper channel 104 eliminates the requirement for the stiffener 70, which, with reference to Figs. 4a-b, is welded to the inner surface of the channel bottom 60 in the upper channel 14 of the prior art. Unlike the upper channel 14 of the prior art, the upper channel 104 does not require the additional structural rigidity provided by the stiffener 70. By eliminating the stiffener 70, the upper channel 104 of the present invention also saves the steps required to weld the stiffener 70 to the channel bottom 60 which are required by the prior art upper channel 14. Moreover, additional assembly steps are saved by integrally casting the threaded hole 186 in the upper channel 104 of the current invention.

  • An additional problem experienced by prior art upper channels 14 is the need to mask openings, such as the holes 68 in the rollers 66 that receive the pins 28 therethrough, when the upper channel is painted or otherwise coated. Specifically, labor is required in order to insert masking material into the openings and then to remove the masking material after the paint has been applied.

As noted above with respect to the upper channel 104, the taper provides more clearance between the upper channel 104 and the lower channel 106 so as to reduce or eliminate the chance of the upper and the lower channels 104, 106 scraping.
