The disclosure relates to truss devices and more particularly pertains to a new truss device for ensuring that the truss is properly assembled after being shipped in a modular, unassembled condition.
An embodiment of the disclosure meets the needs presented above by generally comprising an upper chord and a lower chord. Each of the upper and lower chords has a pair of terminal ends and each of the upper and lower chords may be arcuate between associated ones of the pair of terminal ends. A plurality of branches is removably attached to and extends between the upper and lower chords. Each of the branches has a first end and a second end comprising a saddle that receives one of the upper or lower chords at a fixed angle with respect to the upper and lower chords. The saddles ensure the branches are properly placed on the upper and lower chords.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
The branches 16 each have an upper end 22 and a lower end 24 each comprising a saddle 26 for receiving one of the upper 14 and lower 12 chords, wherein the upper ends 22 engage the upper chord 14 and the lower ends 24 engage the lower chord 12. The saddles 26 are formed in the upper 22 and lower 24 ends. More particularly, the branches 16 each include an upper wall 28, a lower wall 30, a first lateral wall 32 and a second lateral wall 34. The upper walls 28 generally face the upper chord 14 while the lower walls 30 generally face the lower chord 12. As can be seen in the Figures, and in particular
The flanges 38 each have a free end. A distance between the first shoulder 41 and the adjacent free ends is greater than a distance between the second shoulder 42 the adjacent free ends. A distance between the third shoulder 43 and the adjacent free ends is less than a distance between the fourth shoulder 44 and the adjacent free end. When the branches 16 are positioned on the upper 14 and lower 12 chords, the first 41 and second 42 shoulders each abut the upper chord 14 while the third 43 and fourth 44 shoulders each abut the lower chords 12. The first 32 and second 34 lateral walls have a same length with respect to each other such that the free ends of the flanges 38, or first 32 and second 34 lateral walls, are aligned with each other. Because the first 41 and second 42 shoulders are effectively staggered with respect to each other, the branch 16 will not be perpendicular to the upper chord 14 when the upper end 22 receives the upper chord 14 and the first 41 and second 42 shoulders each abut the upper chord 14. The same will be true when each of the third 43 and fourth 44 shoulders abut the lower chord 12. The effect of this structure is that a person assembling the truss system 10 will only be able to place the branches 16 in one direction such that the first 41 through fourth 44 shoulders all abut the upper 14 or lower 12 chord while retaining the upper 14 and lower 12 chords in a correct spatial orientation with respect to each other. That is, the upper 14 and lower 12 chords may only be retained at a correct distance with respect to each other if the branch 16 is properly positioned on the upper 14 and lower 12 chords.
The flanges 38 may include apertures 46 for receiving fasteners 48 that are extendable through the flanges 38 and into either the upper chord 14 or the lower chord 12. The fasteners 48 retain the branches 16 in a static position relative to the upper 14 and lower 12 chords and other ones of the branches 16. As can be seen in the Figures, the branches 16 will be alternated such that moving from one end of the truss system 10 to the other end of the truss system 10 the upper end 22 of one branch 16 will be adjacent to and may abut a next upper end 22 of another branch 16, and the lower end 24 of one branch 16 will be adjacent to and may abut a lower end 24 of another branch 16 to define alternating triangles formed of one of the upper or lower chords and two of the branches. More specifically, the lower walls 30 each form an acute angle with the lower chord 14 and the upper walls 28 each form an obtuse angle with the lower chord 14. Moreover, an angle formed between adjacent ones of said upper walls 28 is between 60° and 120°. As can be seen in
In order to ensure the proper lateral placement of the branches 16 as one moves along the upper 14 and lower 12 chords from one end to the other, the flanges 38 of adjacent ones of the branches 16 may be abutted as shown in
In use, the truss system 10 will be used to form generally conventional trusses which will be used for forming a framework for a storage structure covering. For example, the trusses 10 may be covered with a fabric material such that a covering for grain storage is formed. The terminal brackets 18 may be attached to the upper 14 and lower 12 chords to correctly space them from each other and then the branches 16 are then added, one by one, along the span of the upper 14 and lower 12 chords. It should be understood that the terminal brackets 18 need not be added. The saddles 26 of each branch 16 include a pair of staggered shoulders 41/42 or 43/44 to ensure that the branches 16 are only mounted onto the upper 14 and lower 16 chords in one direction. Moreover, the flanges 38 may have a size and shape for abutment to each other to further provide assurances that the branches 16 are properly spaced with respect to each other. These features allow the truss system 10 to be shipped as a kit without concern that the resulting trusses 10 will be incorrectly assembled. This in turn will dramatically lower the shipping costs as a modular system will use far less container volume for shipping purposes than will pre-assembled trusses.
It should be understood that any measurements shown in the Figures are for example only as these measurements may be altered depending on the size and usage of the truss 10.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure.
