A fastener includes an elongated shaft having a first end, a second end, and a shaft body, a head portion, and a threaded portion. At least one inner feed channel extends through the head portion and the shaft body and terminates proximal to the threaded portion. The fastener has a plurality of flutes formed along and circumferentially spaced around an outer surface of the shaft body and an outer surface of the head portion. Each flute has a first end and extends from a first location proximal to the threaded portion, along the outer surface of the shaft body, and radially outward along the outer surface of the head portion. The fastener further has one or more lateral feed channels formed laterally through the shaft body and connecting the inner feed channel to at least two opposing flutes on the outer surface of the shaft body.

A system for assembling a bracket assembly comprising a base, a coupling guide block, at least one bracket support block and at least one backer guide block. The coupling guide block is coupled to the base and includes a bracket receiving bore on one side and at least one backer receiving bore on an opposite side. The at least one bracket support bracket is coupled to the base and spaced apart from a first side of the coupling guide block. The at least one backer guide block is coupled to the base and spaced apart from a second side of the coupling guide block. Methods are likewise disclosed.

An apparatus for constructing trellis systems, particularly for fruit vines. An apparatus may include a vertical post with a slot for slidably receiving a horizontal crossarm. In certain embodiments, an apparatus may include a vertical post, a horizontal crossarm, and a pair of diagonal crossarms. A vertical post may have slots for slidably receiving a horizontal crossarm and diagonal crossarms. A horizontal crossarm may also have slots for slidably receiving diagonal crossarms. Wire notches may be formed into a vertical post, horizontal crossarm, and/or a diagonal crossarm for attachment to a second apparatus or another stationary object, or for anchoring an apparatus to the ground. The present invention allows for a trellis system which is quickly and easily assembled, and highly durable.

A joint for constructions includes a first element having a first coupling interface, a second element having a second coupling interface, and an interface element configured for coupling to the first coupling interface and the second coupling interface to impose a desired relative angular position on the first element and the second element of the joint. The interface element includes a first positioning structure configured for engaging with the first coupling interface, and includes a second positioning structure configured for engaging with the second coupling interface. The first positioning structure and the second positioning structure of the interface element are angularly staggered with respect to one another.

Seal (3) comprising at least two deformable shells (1,1), each one of the shells containing a component and comprising a membrane, characterized in that bringing the component contained in one shell (1) into contact with the component contained in another shell (1) causes the mixture of the components to crosslink. Use of the seal for wedging electrochemical generators in position in a battery, particularly lithium generators.

A segment for an annular structure is disclosed. The segment includes an arcuate body extending between a first end and a second end. The segment includes a first plurality of interlocking portions extending from the first end and a second plurality of interlocking portions extending from the second end. Each interlocking portion includes a first leg and a second leg partially embedded in the arcuate body and a connecting portion connecting the first leg and the second leg, the connecting portion external to the arcuate body. The segment also includes a flange proximal to the first end and the second end of the arcuate body. Each flange includes a first spacing portion that extends radially outward from the outside surface and a second extending portion that extends distally from the main body portion.

In various representative aspects, an assembly for connecting and electrically bonding electronic equipment to solar panel frames is provided. More specifically, the present invention relates generally to an assembly for securing and installing micro inverter and power optimizer units for use with solar panel arrays that are typically installed on roof structures. The assembly comprises a bracket assembly that couples micro invertors and power optimizers to solar panel frames.
