The present invention generally relates to a clamp. More specifically, the invention is a module purlin clamp.
It is an object of the invention to provide a C-shaped module purlin clamp that provides ease of installation and tolerance adjustment for a solar module type of module in a carport installation.
It is an object of the invention to provide a module purlin clamp that can slide along the length of a supporting purlin to allow one or more connections at any location along the purlin, and has a top slot to allow for an adjustment tolerance in an opposite direction.
It is an object of the invention to provide a module purlin clamp that has an installation tolerance that includes a screw that self-spaces the module.
What is really needed is a module purlin clamp that provides ease of installation and tolerance adjustment for a solar module type of module in a carport installation that can slide along the length of a supporting purlin to allow one or more connections at any location along the purlin, and has a top slot to allow for an adjustment tolerance in an opposite direction that has an installation tolerance that includes a screw that self-spaces the module.
The present invention will be described by way of exemplary embodiments, but not limitations, illustrated in the accompanying drawing in which like references denote similar elements, and in which:
Various aspects of the illustrative embodiments will be described using terms commonly employed by those skilled in the art to convey the substance of their work to others skilled in the art. However, it will be apparent to those skilled in the art that the present invention may be practiced with only some of the described aspects. For purposes of explanation, specific numbers, materials and configurations are set forth in order to provide a thorough understanding of the illustrative embodiments. However, it will be apparent to one skilled in the art that the present invention may be practiced without the specific details. In other instances, well-known features are omitted or simplified in order not to obscure the illustrative embodiments.
Various operations will be described as multiple discrete operations, in turn, in a manner that is most helpful in understanding the present invention. However, the order of description should not be construed as to imply that these operations are necessarily order dependent. In particular, these operations need not be performed in the order of presentation.
The phrase “in one embodiment” is used repeatedly. The phrase generally does not refer to the same embodiment, however, it may. The terms “comprising”, “having” and “including” are synonymous, unless the context dictates otherwise.
The bent bracket 210 is a C-shaped bracket 212 with a perpendicular downward edge 214 disposed on the top 215 of the bent bracket 210 and a perpendicular upward edge 216 disposed on the bottom 218 of the bent bracket 210. The clamp portion 220 is a perpendicular clamp 222 with a vertical side 224, a horizontal side 226 and a curved outer edge 228 on the horizontal side 226. The vertical side 224 has an aperture 225 disposed on the vertical side 224. The horizontal side 226 has a slot 227 disposed lengthwise on a middle portion 229 of the horizontal side 226. The bolt stack fastener 230 includes a flange head locknut 231, a mid-clamp 232, a head nut 233, an unthreaded spacer 234, a washer 235, a tooth lock washer 236 and a first cap screw 237. The first cap screw 237 is inserted upwards through the slot 227 on the horizontal side 226 of the clamp portion 220. The flange head locknut 231 is placed on top of the first cap screw 237. The mid-clamp 232 is placed underneath the flange head locknut 231 on the first cap screw 237 and the head nut 233 is placed underneath the flange head locknut 231 on the first cap screw 237. The unthreaded spacer 234 is placed underneath the head nut 233 on the first cap screw 237 and the washer 235 is placed underneath the unthreaded spacer 234 on the first cap screw 237. The tooth lock washer 236 provides additional strength to the bolt stack fastener 230 that is placed underneath the washer 235 on the first cap screw 237.
The inverted L-shaped bracket 240 has a vertical side 242 and a horizontal side 244. The vertical side 242 includes a perpendicular protruding top edge 246 and centered aperture 248. The horizontal side 244 has a pair of centered slots 241 extending inward from the edges 243 of the horizontal side 244. The second cap screw 250 is inserted through the aperture 225 disposed on the vertical side 224 of the clamp portion 220 and the centered aperture 248 of the vertical side 242 of the inverted L-shaped bracket 240 that are correspondingly aligned to receive the second cap screw 250. The second cap screw 250 releasably secures the clamp portion 220 and the inverted L-shaped bracket 240 together.
The module purlin clamp provides ease of installation and tolerance adjustment for any suitable solar module type in a suitable carport installation. It can slide along the length of a supporting purlin to allow connections at any locations, and has a slot to allow for an approximate +/−0.75″ adjustment tolerance in an opposite direction. In addition to the installation tolerance, the screw has an approximate 0.50″ spacer included so that it self-spaces the modules, which saves labor.
The use of the module purlin clamp is traditionally intended for carport solar installations with a C-shaped purlin supporting structure. The module purlin clamp contains 3 main parts that include a bent galvanized steel bracket, which matches the width of the supporting purlin, a bent galvanized steel clamp, which tightens the assembly to a supporting purlin, and a bolt stack assembly for spacing and securing the modules.
While the present invention has been related in terms of the foregoing embodiments, those skilled in the art will recognize that the invention is not limited to the embodiments described. The present invention can be practiced with modification and alteration within the spirit and scope of the appended claims. Thus, the description is to be regarded as illustrative instead of restrictive on the present invention.
