DETAILED DESCRIPTION OF THE INVENTION

(12) The present invention is an assembly 10 for mounting panels, such as photovoltaic panels.

(13) The assembly includes a base 12, a rail device 30 and a fastener 31 for securing the rail device to the base.

(14) The base 12 includes an attachment plate 13 and two perpendicularly arranged opposing walls 14, 16 within which the rail device 30 may be installed. The opposing walls 14, 16 include outer surfaces 18, 20 and inner surfaces 22, 24.

(15) The opposing walls 14, 16 comprise multiple parallel ridges 26 on the inner surface 22 and similar multiple parallel ridges 28 on inner surface 24.

(16) The design of the base 12 can include a number of embodiments. For example, as illustrated in FIG. 1, the opposing walls 14 and 16 of the base 12 may each include corresponding vertically elongated openings 15 and 17 where the vertical distance of the opening is greater than the horizontal distance of the opening. The openings 15 and 17 allow a fastener 31 to pass through the corresponding openings 15 and 17 and allow a rail device 30 to be removably affixed to the base 12 at varying heights along the opposing walls 14 and 16. By tightening the fastener 31, the opposing walls 14 and 16 are further compressed against the rail device 30. Providing holes 88 along the length of the rail device 30 allows the rail to be affixed to the base with a fastener 31 at various points along the length of the rail device.

(17) Additionally, in some embodiments, the rail device 30 may be releasably affixed to the base 12 with a fastener 31 without the need for the fastener 31 to pass through holes 88 in the rail device 30. The openings 15 and 17 for the fastener 31 can be positioned on the opposing walls 14 and 16 of the base such that the fastener 31 can be tightened, compressing the opposing walls 14 and 16 while not requiring the fastener to pass through the body of the rail device 30. For example, the opposing walls 14 and 16 could be sufficiently tall such that the fastener can pass over the top wall 47 of the rail device 30. In another example, illustrated in FIG. 11, the end of the rail device might be positioned in the base 12 such that the end is not inserted into the base past the point where the fastener 31 connects through the base 12, thereby allowing the opposing walls 14 and 16 to be compressed further around the rail device 30 without the need for the fastener 31 to pass through the rail device 30.

(18) In another example, as illustrated in FIGS. 9 and 10, the opposing walls 14 and 16 of the base 12 may each include two or more corresponding vertical extended openings 15, 17, 19, and 21, where the vertical distance of the openings are greater than the horizontal distance of the openings. The openings 15, 17, 19, and 21 allow fasteners 31 to pass through the corresponding sets of openings (15 to 17 and 19 to 21) and allow for a rail device 30 to be removably affixed at multiple points to the base 12 at varying heights along the opposing walls 14 and 16. The multiple sets of corresponding openings also allows the base 12 to act as an external splice enabling the ends of two different rail devices 30 and 30A to be removably affixed to one base 12 thereby extending the length of the rail device 30. This embodiment allows the base 12 to both attach the rail device 30 to a surface and splice two rail devices 30 and 30A. As illustrated in FIG. 11, the external splicing ability of the base 12 can also be accomplished with a single set of vertically elongated openings 15 and 17, by inserting opposing ends of rail devices 30 and 30A up to the fastener 31 and tightening the fastener 31 to further compress the opposing walls 14 and 16 against the end of both rail devices 30 and 30A. It should be understood that the above are merely examples of how the based is designed to releasably attach to the rail device and should not be limiting.

(19) The rail device 30 can be any structural profile used to span distances between bases 12 and is configured to receive clamp assemblies 53. The design of the rail device 30 can include a number of embodiments including tubes, rails, pipes, supports, rods, beams, etc. Preferably, the rail device 30 is made out of aluminum or steel. In embodiments where all rail devices 30 installed are made out of aluminum or steel, it is possible to take advantage of the use of aluminum and steel such that the rail devices 30 can be used to create a bonding path to electrically bond the device 10. As illustrated in FIG. 11, a base embodiment of the rail device 30 comprises outer walls 72 and 74, a bottom surface 84, and a top surface 86. The outer walls 72 and 74 having exterior surfaces 76 and 78. Similar to the inner surfaces 22 and 24 of the base 12, the exterior surfaces 76 and 78 each comprise multiple parallel ridges 80 and 82. The top surface 86 is configured to receive at least one clamp assembly 53.

(20) In another embodiment, as illustrated in FIGS. 1-3 and 5, the rail device 30 comprises upper outer walls 32, 34 having exterior surfaces 36, 38. Similar to the inner surfaces 22, 24 of the base 12, the exterior surfaces 36, 38 each comprise multiple parallel ridges 40, 42. The rail device 30 further comprises lower outer walls 35, 37 each having ridges 39, 41, a bottom surface 45, and a split top surface 47. The split top surface 47 includes a series of ridges 49, 51, which purpose is to assist in seating clamp assembly 53, illustrated in FIGS. 1-3. In addition, the ridges 49, 51 can be used to assist in mating any other device with corresponding ridges to the split top surface 47 of the rail device 30. For example, a second rail device 30 with corresponding ridges on the bottom surface 45 could be seated on top of the existing rail device 30. It is sometimes necessary to add a second rail device 30 either parallel to or perpendicular to the existing rail device 30. The ridges 49, 51 add an element of friction to better seat the second rail device 30 and, in embodiments where the rail devices 30 are made of steel or aluminum, provide a bonding path to electrically bond the device 10.

(21) Each of the multiple parallel ridges 26, 28, 40, 42, 39, 41, 80, 82 are formed of peaks and valleys enabling the base ridges 26, 28 to correspondingly mate with the rail device ridges 39, 40, 41, and 42 or 80 and 82 of the base embodiment of the rail device 30.

(22) The ridges 26, 28 of the opposing base walls 14, 16 cooperate with ridges 39, 40, 41, 42 (or 80 and 82) to form an adjustable mating surface on corresponding outer walls 32, 34, 35, 37 of the rail device 30 (or outer walls 72 and 74 of the base embodiment of the rail device 30) to temporarily secure the rail device 30 to the base 12 without the need for a fastener and without the need to manually hold the rail device 30 at the desired height until it is secured to the base 12. The opposing side walls 14, 16 are preferably angled slightly inwards to assist in compressing the outer walls 32, 34, 35, 37 (or outer walls 72 and 74 of the base embodiment of the rail device 30) against the inner surface 22, 24 of the opposing side walls 14, 16, thus assisting in temporarily securing the side walls 14, 16 to the rail device 30.

(23) The ridges 39, 41, 40, 42 (or 80 and 82 of the base embodiment) further enable vertical positioning of the rail device 30, i.e., height or distance from the attachment plate 13, as the rail device 30 can be adjustably mounted at various heights along the walls 14, 16 of the base 12. The ridges allow the height of the rail 30 to be temporarily secured without the need for a fastener 31 and without the need to manually hold the rail device 30 at the desired height while affixing it to the base 12.

(24) Additionally, when opposing walls 14 and 16 of the base 12 are affixed to the rail device 30 using a fastener 31, the ridges 39, 41, 40, 42 (or 80 and 82 of the base embodiment) mated with ridges 26 and 28 cause the rail device 30 to be more securely fastened to the base 12. In embodiments where a fastener 31 is used to affix rail devices 30 to the base 12, the outer walls 72 and 74 of the rail device 30 will have holes 88 bore through the width of the rail device 30 spanning from one outer wall 72 to the opposing outer wall 74 such that the fastener 31 can pass through the body of the rail device 30. The holes 88 can be positioned at any necessary or desired point along the length of the rail device 30. Optionally, the hole 88 can be placed incrementally along the length of the rail device 30 or they can be placed as needed along the length of the rail device 30.

(25) One embodiment of the clamp 53 is illustrated in FIGS. 1-3. As illustrated in FIGS. 1-3, the clamp 53 is designed to be seated on the split top surface 47 of the embodiment of the rail device 30 also illustrated in FIGS. 1-3. The clamp 53 is secured to the rail device 30 by T-bolt 52, the head of which is placed in slot 50. Slot 50 is specifically formed within the rail device 30. Slot 50 allows for accommodating T-bolts 52 of varying lengths and allows for the securement of modules and panels of different thicknesses to the rail device 30. As illustrated in FIG. 5, slot 50 is bifurcated into an upper slot 54 and a lower slot 56. The upper and lower slots 54, 56 are separated by partial walls 57, 58, which form a channel 59 for allowing passage of the shaft of the T-bolt 52. The clamp 53 is secured to the rail device 30 by tightening the T-bolt 52 in a manner known to the art. The split partial walls 57 and 58 allow for the T-bolt to be secured either in the upper slot 54 or the lower slot 56, which allows the clamp 53 to accommodate a variety of panel thicknesses. Reference is made to U.S. patent application Ser. No. 16/155,834 in the name of Jonathan Young and entitled PANEL MOUNTING DEVICE, which is incorporated herein in its entirety for a description of the panel mounting device and clamp. It should be understood that the above is merely one embodiment of the clamp 53 and should not be limiting. The clamp 53 can be any device configured to affix to the top surface 86 or 47 of the rail device 30 and configured to secure a panel/module to the rail device 30. It should further be understood that the T-bolt 52 is one embodiment of a fastener for the clamp 53 and should not be limiting. The fastener for the clamp 52 can be any fastener capable of releasably attaching the clamp to the top surface 86 or 47 of the rail device 30.

(26) Referring now to FIGS. 6-8, there is shown an exemplary view of the manner of utilizing the assembly 10 on the roof 60 of a building, wherein the roof 60 includes a wood-frame truss 62. Referring to FIGS. 7 and 8, the base 12 and rail device 30 are readily apparent wherein the clamp 53 is used to secure a panel 64, such as a solar panel, to the rail devices 30 which, accordingly, is mounted to the roof 60. It should be noted that FIGS. 6-8 are merely examples of how the assembly 10 can be mounted and should not be considered limiting. The assembly 10 can be attached to any wood structure or steel structure. The assembly 10 can further be attached to any roofing structural member, including, for example, steel purlins. Advantageously, the assembly 10 can be used to mount side-by-side panels 64, as illustrated in FIG. 7, or as an end mount, as illustrated in FIG. 8. As discussed above and illustrated in FIGS. 9-11, the base 12 of the assembly 10 can also be used as an external splice to join the ends of two rail devices 30 and 30A, thereby extending the length of the rail devices 30 and 30A. The ability for the base 12 to externally splice rail devices 30 reduces the need for internal splicing devices, simplifies the installation process, and reduces the weight of the system on the surface/roof.
