DETAILED DESCRIPTION
[0032] As previously described, the present invention discloses an elevated cradle for supporting any number of flexible conduits (e.g. hoses and electrical codes) extending between and used in standard operation of a truck tractor and accompanying towed truck trailer. Referring first to
[0033] In one non-limiting variant, the invention 10 in one configuration can incorporate three basic components, a hose cradle assembly 20, a substantially upright or vertical support member or rod 30 and a base assembly 40. These components are shown in perspective in
[0034] The upper portion 33 of support 30 further contains a plurality of vertically aligning holes 35 extending theretbrough and the lower portion 34 of support 30 has a plurality of corresponding vertically aligned holes 36 extending therethrough. When lower portion 34 is inserted within upper portion 33 of support 30, one extending, hole 35 is aligned with one extending hole 36 and a pin 17 is inserted, as shown in
[0035] Support 30 is rigidly attached at its lower end 32 to base assembly 40. The method of such attachment is not in limitation of the invention 10 and may be a bolt 38, either conformably threaded with a conforming aperture 39 in base assembly 40, or passing through aperture 39 and held by a corresponding threaded bolt 39 a as shown inFIG. 6 or by welding or other common means.
[0036] The hose support cradle assembly 20 is mounted on the upper end 31 of the support 30. The primary cradle member or body 21 has a first end 22 and a second end 23 and is inwardly and downwardly concave as particularly illustrated in
[0037] Because the inwardly concave interior surface 24 of cradle 21 with sides 21a and 21b extending outwardly and upwardly as shown in
[0038] Cradle member 21 of cradle assembly 20 is radially curved from first end 22 to second end 23 within a range of 1 to 90 over and about the upper end 31 of support 30. In the embodiments shown, cradle 21 rests on upper end 3 lof support 30 approximately equidistant between first end 22 and second end 23.
[0039] The main cradle body 21 is held moveably in place on upper end 31 of support 30 by one or more extension springs27, with at least one extension spring 27 attached to the first side 21a of cradle 21, and at least one extension spring 27 attached to the second side 21b, of cradle 21. As will be described in additional detail, an advantage of utilizing springs or other resiliently deformable structure is to provide any degree of multi-axial bending, pivoting or rotating motion, depicted as x, y and z arrow designations at 25, 27 and 29 in
[0040] When one extension spring 27 is used on each of sides 21a and 21b of cradle 21, each is attached at its first end 27a directly above support 30 and extends directly downward and is attached as its second end 27b to support 30 proximate upper end 31, as shown in
[0041] In
[0042] As seen from the drawings, in particular as designated by arrows previously identified at 25, 27 and 29, the use of extension springs 27 will allow cradle 21 to pivot on upper end 31 of Support 30, in each of fore and aft, side to side and, when necessary, up and down. In one non-limiting application, a pair of equal extension springs 27 are placed on each of sides 21a and 21b, from side to side as well, with the cradle 21 being returnable to its original position, as shown, by contraction of extension springs 27.
[0043] Without limitation, the radial curve of the main cradle body or portion 21 from the first end 22 to the second end 23 can exhibit any arcuate dimension as measured in degrees and, in one variant, can exhibit a range of 45 to 90. The unitary radial concave surface, among other advantages, holds the conduits 11 without kinking, and minimizes single point abrasion by spreading contact of the conduit 11 equally over the entire bottom inner concave surface of the cradle 21 from the first end 22 to the second end 23.
[0044] In addition to the essentially 360 movement provided for cradle assembly 20 atop the support assembly 30, additional flexible movement of the device is provided by base assembly 40 shown in cross-section 6-6 of
[0045] Base assembly 40 is comprised of two plates, positioned substantially in parallel. A lower plate member 41 with a defined perimeter edge 42, also has a top side 43 and a bottom side 44. The bottom side 44 is positioned in contact with bed 14 of truck tractor 12 when the device 10 is used in standard operation. Lower plate 41 further defines an aperture 45 through which a bolt or other fastening device may be inserted to hold the device 10 in contact with bed 14. In practice, the invention is not limited by the method of affixing lower plate 41 to bed 14, and straps or clamps or other means sufficient to maintain contact under force may be used. Positioned above lower plate 41 is upper plate 50, which, as stated, is substantially in parallel with lower plate 41. Upper plate 50 has a defined perimeter 52, substantially corresponding with the perimeter 42 of lower plate 41. Upper plate 50 has a top side 53 and a bottom side 54.
[0046] A plurality of supporting lower compression springs 60 are spaced equidistantly around the perimeter of lower plate 41, as shown in
[0047] Upper plate 50 has a plurality of holes or apertures 51, corresponding and equal to the number of lower compression springs. Each aperture 51 is centered above a corresponding lower compression spring 60. Each lower compression spring 60 has a lower end 61 and an upper end 62 and all of the plurality of lower compression springs 60 are of equal length which, at rest, is distance B, and are placed between the bottom side 54 of upper plate 50 and the top side 43 of bottom plate 41.
[0048] A plurality of upper compression springs 70 rest upon top side 53 of upper plate 50 and correspond with the plurality of lower compression springs 60, and the plurality of apertures 51 in upper plate 50. Each upper compression spring 70 is centered on top side 53 over a corresponding aperture 51.
[0049] Moveably expandable within each lower compression spring 60 is a contained extension spring 71. Each extension spring 71 has a first end 71a attached to bottom plate 41 directly below the corresponding lower compression spring member 60 within which it is contained. The method of attachment of spring 71 to bottom plate 41 does not limit the invention, but in the embodiments shown is accomplished by a clevis-type pin member 72 extending upwardly through a corresponding aperture 73 through bottom plate 41. As used herein, clevis-type means an unthreaded pin with a perpendicular hole 74, through which the corresponding first end 71 a and extension spring 71 may be inserted. Each extension spring 71 further has a second end 71b.
[0050] A plurality of clevis-type bolts 80 corresponding to the plurality of upper compression sprigs 70 extend downward through upper compression spring 70 and into each aperture 51 in upper plate 50. Each bolt 80 has an upper end 81and a lower end 82.
[0051] As used herein, a clevis-type bolt is a threaded headless bolt having perpendicular hole or orifice 83 perpendicularly therethrough. In the embodiment shown, lower end 82 of clevis-type bolt 80 is connected to its corresponding extension spring 71, by insertion of second end 71b through orifice 83 as shown in
[0052] Thus, in operation of device 10, when pressure from the supported flexible conduits 11 exerts any directional force against the cradle assembly 20 and against the support assembly 30 the upper compression springs 70 and lower compression springs 60 on opposite sides of upper plate 50 compress with the force, showing upper plate 50 to returnably tilt in the direction in which the force is being asserted, easing pressure on support 30, and cradle assembly 20, with the contained extension springs 71 returning the upper plate 50 to substantially horizontal position, parallel to lower plate 41 after the force has subsided.
[0053] In the preferred embodiment shown in the drawings, four combination compression/extension spring assemblies, each comprised of a lower compression spring 60, an upper compression spring 70, and contained extension spring 71 are utilized, through other pluralities of such assemblies, spaced equidistant around perimeters 42 and 53and between upper plate 50 and lower plate 41 would suffice. As further referenced in
[0054] It is envisioned that the support and base assemblies as described can, in further variants, be substituted by a single elongate tabular member, such as which includes at least an upper elongate portion as shown at 33 as depicted in
