Abstract
Abstract A device is used to connect one rod to at least one other object, such as another rod. This device can be used in accordance with a claimed method to form a lattice, such as an equipment lattice, made of a plurality of rods and at least one connecting device. The device employs a channel to permit press-fitting a rod into the channel. In a preferred embodiment, the device has a tetrahedral body with two orthogonal channels.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
112 words
A device for connecting crossed rods, such device comprising: a body, of resilient material and having a predominantly tetrahedral shape, in which there have been formed two straight, open-ended channels, located along two non-adjacent edges of the body, in such a way that walls of each such channel are capable of gripping one of the rods each of said channels encompassing an arc of more than 180° and terminating in opposed edges defining the open end therof and with each edge of a respective channel also defining the edge of a beveled face extending from an opposite face of the tetrahedron and beveled inwardly toward the channel and the opposite beveled face.
Claim 2
Independent Claim
