Abstract
Abstract A lightweight mounting structure combination for small dish antennae is provided. The structure includes an upright mast for supporting the dish antennae. The mast has an upper end for attachment to said dish and a lower end for anchoring to a rigid-type structure. The structure also has a bent strut having a lower end for anchoring to a rigid-type structure and an upper end for attachment to said mast. In addition, a second strut is provided having a lower end for anchoring to a rigid-type structure and an upper end for attachment to said mast. Further included is means for anchoring the respective lower ends of the mast, bent strut and second strut to the rigid-type structure and for attaching the respective upper ends of the bent and second struts to the mast. The means includes a bracket, a threaded bolt having a shank portion for extending through the bracket and respective end, and a nut threaded on said bolt for drawing the bracket and respective end tightly together. The bolt, nut, bracket and respective end cooperate to indicate to one tightening the nut and bolt when a predetermined extent of tightness is attained, the predetermined extent of tightness being characterized by the respective end having undergone a predetermined extent of deformation such that relative movement between the bracket and respective end is minimized. A bolted joint connection and a method for installing a dish antenna mounting structure are also provided.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
355 words
A lightweight mounting structure combination for dish antennae comprising: an upright vertically extending mast for supporting said dish antennae, said mast having an upper end for attachment to said dish and a lower end for anchoring to a rigid-type structure; a bent strut having a lower end for anchoring to a rigid-type structure and an upper end for attachment to said mast; a second strut having a lower end for anchoring to a rigid-type structure and an upper end for attachment to said mast; means for anchoring the respective ends of the mast, the bent strut and the second strut to the rigid-type structure, said means including for each respective lower end an anchor bracket, a threaded bolt having a shank portion for extending through said bracket and respective lower end, and a nut threaded on said bolt for drawing said anchor bracket and respective lower end tightly together, said bolt, nut, anchor bracket and respective lower end cooperating to indicate to one tightening the nut and bolt when a predetermined extent of tightness is attained, said predetermined extent of tightness being characterized by said respective lower end having undergone a predetermined extent of deformation such that relative movement between the bracket and respective lower end is minimized; means for attaching the upper ends of the bent strut and the second strut to the mast's midsection, said means including a bracket, a threaded bolt having a shank portion for extending through the respective upper end and at least a portion of the bracket and a nut threaded on said bolt for drawing said bracket and respective upper end tightly together, said bolt, nut, bracket and respective upper end cooperating to indicate to one tightening the nut and bolt when a predetermined extent of tightness is attained, said predetermined extent of tightness being characterized by said respective upper end having undergone a predetermined amount of deformation such that relative movement between the bracket and respective strut is minimized; the anchoring and attaching means allowing the mounting structure to be mounted on vertically and horizontally extending rigid-type structures, and on structures disposed at all angles in between.

A lightweight mounting structure combination for dish antennae comprising: an upright vertically extending mast for supporting said dish antennae, said mast having an upper end for attachment to said dish and a lower end for anchoring to a rigid-type structure; a bent strut having a lower end for anchoring to a rigid-type structure and an upper end for attachment to said mast; a second strut having a lower end for anchoring to a rigid-type structure and an upper end for attachment to said mast; means for anchoring the respective ends of the mast, the bent strut and the second strut to the rigid-type structure, said means including for each respective lower end an anchor bracket, a threaded bolt having a shank portion for extending through said bracket and respective lower end, and a nut threaded on said bolt for drawing said anchor bracket and respective lower end tightly together, said bolt, nut, anchor bracket and respective lower end cooperating to indicate to one tightening the nut and bolt when a predetermined extent of tightness is attained, said predetermined extent of tightness being characterized by said respective lower end having undergone a predetermined extent of deformation such that relative movement between the bracket and respective lower end is minimized; means for attaching the upper ends of the bent strut and the second strut to the mast's midsection, said means including a bracket, a threaded bolt having a shank portion for extending through the respective upper end and at least a portion of the bracket and a nut threaded on said bolt for drawing said bracket and respective upper end tightly together, said bolt, nut, bracket and respective upper end cooperating to indicate to one tightening the nut and bolt when a predetermined extent of tightness is attained, said predetermined extent of tightness being characterized by said respective upper end having undergone a predetermined amount of deformation such that relative movement between the bracket and respective strut is minimized; the anchoring and attaching means allowing the mounting structure to be mounted on vertically and horizontally extending rigid-type structures, and on structures disposed at all angles in between.
Claim 3
Dependent Claim
85 words
The combination of claim 1 wherein the mast and struts are tubular structures and the attaching and anchoring means include bolts provided with a predetermined length, nuts provided with a predetermined depth, and tubular structures provided with a predetermined diameter, thickness and elasticity, all of which cooperate to indicate to one tightening the respective nut and bolt that the predetermined extent of tightness is attained when the exposed end surface of the respective nut is flush with the end surface of the respective bolt shank.
Claim 4
Dependent Claim
79 words
The combination of claim 1 wherein the mast and struts are tubular structures and the attaching and anchoring means include bolts provided with a predetermined amount of thread and tubular structures provided with a predetermined diameter, thickness and elasticity, all of which cooperate to indicate that the predetermined extent of tightness is attained when the nut and bolt cannot be further tightened, thereby also indicating that the nut has reached the end of the threads provided on the bolt.
Claim 5
Dependent Claim
78 words
The combination of claim 1 wherein the mast and struts are tubular structures and the attaching and anchoring means include the nuts provided with a predetermined depth, tubular structures provided with a predetermined diameter, thickness and elasticity, and bolts provided with a mark on their shanks, all of which cooperate to indicate that the predetermined extent of tightness is attained when the exposed end surface of the nut is flush with the mark provided on the bolt shank.
