A fixture 10 for supporting, containing, and transferring articles in an industrial process is shown in
The fixture 10 can comprise a plurality of elongate members 12 comprising a plurality of first elongate members 16 (16a-16f), a plurality of second elongate members 18 (18a-18e), and a plurality of third elongate members 20 (20a-20k). The plurality of first elongate members 16 each extend longitudinally in a first direction X, the plurality of second elongate members 18 each extend longitudinally in a second direction Y that is substantially perpendicular to the first direction X, and the plurality of third elongate members 20 each extend longitudinally in a third direction Z that is substantially perpendicular to the first direction X and the second direction Y. Notably, the fixture 10 may comprise other elongated members that do not extend longitudinally in any of directions X, Y and Z and rather may extend longitudinally in a direction transverse to directions X, Y and Z without departing from the scope of the invention.
The plurality of first elongate members 16 can each comprise a rod member 24 having a length L1 and two end portions 26, as shown in
The plurality of first elongate members 16 will preferably all have identical or substantially identical structure. By having identical or substantially identical structure, the manufacturing process for creating the plurality of first elongate members 16 is simplified because the same process can be used for all of the members, thus lowering manufacturing costs for the fixture 10. However, the plurality of first elongate members 16 may have structure that is different with respect to one another without departing from the scope of the invention. For example, the lengths of the rod member 24 and the one or more spacers 28 may vary for each first elongate member 16.
The plurality of second and third elongate members 18, 20 can each comprise a flat stock member 32, examples of which are shown in
The flat stock member 32 can comprise one or more connecting portions 40, each connecting portion having an aperture 42 extending through the flat stock member 32 from the first major surface 34 to the second major surface 36. The flat stock member 32 can further comprise one or more intermediate portions 44 joining the connecting portions 40. For example, the flat stock member 32 can comprise a first connecting portion 40a having a first aperture 42a extending therethrough along a first axis X1, a second connecting portion 40b having a second aperture 42b extending therethrough along a second axis X2, and an intermediate portion 44a joining the first and second connecting portions 40a, 40b. In some examples, the flat stock member 32 can comprise more than two connecting portions 40 and apertures 42 and more than one intermediate portion 44. The axes of the apertures 42 can be substantially parallel to each other and aligned to intersect substantially perpendicular with a longitudinal axis Y1 of the flat stock member 32. However, in some examples, the axes can be transverse to each other and/or non-intersecting with the longitudinal axis
The flat stock member 32 can comprise a number of different shapes. For example, as shown in
Alternatively, as shown in
The plurality of second and third elongate members 18, 20 can each comprise the flat stock member 32 according to any of the configurations discussed above. Moreover, plurality of second and third elongate members 18, 20 need not all comprise the flat stock member 32 according to the same configuration. For example, the shape, size, number of connecting portions 40, and number of intermediate portions 44 for the flat stock member 32 can vary for each of the second and third elongate members 18, 20. For instance, as can be seen in
The plurality of elongate members 12 are non-integral with each other and can be movably coupled together to form a support platform 50 for supporting articles that extends along a support plane P, as shown in
The plurality of elongate members 12 can be movably coupled together by extending the rod member 24 of one of the first elongate members 16 through the apertures 42 of a second elongate member 18 and a third elongate member 20 and then forming a riveted portion at one or both end portions 26 of the rod member 24. For example, as can be seen in
For embodiments wherein one or more of the first elongate members 16 comprises one or more spacers 28, the one or more spacers 28 can be used to help maintain the structure of the fixture 10 by defining a minimum and/or maximum distance between one of the plurality of second and third elongate members 18, 20 and another one of the plurality of second and third elongate members 18, 20. For example, as can be seen in
Turning now to
The handle member 60 can be movably coupled to the plurality of elongated members 12 by extending the rod member 24 of one of the first elongate members 16 through an aperture 66 of the handle member 60 and an aperture 42 of one of the second elongate members 18 and/or an aperture 42 of one of the third elongate members 20. A riveted portion at the end portion 26 of the rod member 24 may then be formed to provide a riveted coupling. For example, as can be seen in
In some embodiments, some of the members 12, 60 of the fixture 10 may be coupled together using a riveted coupling as described above while some of the members 12, 60 may be coupled together using other forms of coupling such as, for example, bolting or welding. In other embodiments, all of the members 12, 60 can be movably coupled together using riveted couplings such that all of the members 12, 60 are movably coupled to each other without any welding. Preferably, the fixture 10 will have no welding that forms a load-bearing joint between any of its members 12, 60. Coupling the members 12, 60 together with riveted couplings instead of welds can allow for members 12, 60 of different materials to be coupled together that otherwise could not be coupled together via welds due to the differing properties of their materials.
For example, in some embodiments, one of the plurality of elongate members 12 can comprise a first material and another one of the plurality of elongate members 12 that is coupled thereto can comprise a second material that is different from the first material. For instance, as shown in
As another example, in some embodiments, the handle member 60 can comprise a first material and one of the plurality of elongate members 12 that is coupled thereto can comprise a second material that is different from the first material. For instance, as shown in
As yet another example, in some embodiments, the fixture 10 can comprise a plane of demarcation D that divides the fixture 10 into a top portion 68 and a bottom portion 70, the top portion 68 being above the bottom portion 70 relative to the support plane P. In such embodiments, the members 12, 60 located in the bottom portion 62 can comprise a first material while members 12, 60 located in the top portion 60 can comprise a second material. More specifically, the second material for the members 12, 60 located in the bottom portion 62 can comprise a high thermal strength material such as, for example, nickel alloy, that can withstand high thermal loads or highly corrosive applications. Meanwhile, because the members 12, 60 located in the top portion 60 will experience relatively less severe conditions than the alternately positioned members 12, 60 located in the bottom portion 62, the first material for the members 12, 60 located in the top portion 60 may comprise a material that is lower in thermal strength but less costly than the first material (e.g., lower alloy metal or carbon steel).
Although the above examples describe embodiments wherein some of the members 12, 60 comprise different materials, it is to be noted that in some embodiments, the members 12, 60 may all comprise the same material without departing from the scope of the invention. Moreover, although the above examples describe embodiments wherein one of the members 12, 60 comprises a first material while another one of the members 12, 60 comprises a second material, there may be embodiments wherein other members 12, 60 comprise one or more materials dissimilar to the first and second material without departing from the scope of the invention. Indeed, there may be embodiments wherein every one of the members 12, 60 comprises a material different from the rest of the members 12, 60.
Turning now to
The plurality of stacking members 72 can comprise one or more first stacking members 74 and one or more second stacking members 76. Each of the first stacking members 74 comprises a first stacking portion 78 while each of the second stacking members comprises a second stacking portion 80. The first and second stacking portions 78, 80 can comprise any structure that can mate and/or interlock with each other. For example, the first stacking portion(s) 78 of the fixture 10 can comprise a recess while the second stacking portion(s) 80 of the fixture 10 can comprise a projection that is receivable within the recess and can interlock with the first stacking portion(s) 78. As another example, the second stacking portion(s) 80 of the fixture 10 can comprise a recess and the first stacking portion(s) 78 of the fixture 10 can comprise a projection that is receivable within the recess and can interlock with the second stacking portion(s) 80.
The first and second stacking members 74, 76 of the fixture 10 can be arranged to mate with stacking members of another fixture. For example, as shown in
It is to be noted that the fixture 10 may or may not comprise the plurality of stacking members 72 without departing from the scope of the invention. It is further to be noted that although the fixture 10 may comprise first and second stacking members 74, 76 arranged to mate with the first and second stacking members 174, 176 of the identical fixture 110, it is not intended that the identical fixture 110 be present for the fixture 10 to be within the scope of the invention. For example, in some embodiments, the fixture 10 may be stacked with a non-identical fixture. As another example, in some embodiments, a second fixture may not even be present. For instance, the fixture 10 may be by itself but comprise first and second stacking members 74, 76 arranged such that when the fixture 10 is stacked with an identical fixture with their wall portions aligned, the first stacking portion(s) 78 of the fixture 10 will mate with the second stacking portion(s) of the identical fixture.
Illustrative embodiments have been described, hereinabove. It will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the claimed invention. It is intended to include all such modifications and alterations within the scope of the present invention.
