Abstract
Abstract A light pole having a support at the top of the pole and a light-carrying structure encircling the pole. A first fixed suspension is provided depending downwardly from the support and a second fixed suspension is provided on the light-carrying structure. The first and second fixed suspensions cooperate to detachably suspend the light-carrying structure from the support at a first position just beneath the support. A cable system extends from the support to the light-carrying structure for use in lowering the light-carrying structure down the pole for servicing the lights and for raising it back to the first position. The cable system is offset circumferentially with respect to the first suspension in order to impart a slight rotation of the light-carrying structure during the engagement and disengagement of the first and second suspensions. This rotation provides an easy and secure engagement and disengagement of the first and second suspensions with each other. The pole is provided at its bottom end with facilities for detachably receiving, within and without the pole, a control system for the cable system to raise and lower the light-carrying structure.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
145 words
A lighting structure comprising: a. a pole; b. a support means carried by the upper end of the pole; c. a light-carrying structure encircling the pole; d. a first fixed suspension means carried by the support means; e. a second fixed suspension means carried by the light-carrying structure whereby the first and second fixed suspension means are interengageable to detachably suspend the light-carrying structure from the support means; and f. cable means extending from the support means to the light-carrying structure for raising and lower the light-carrying structure on the pole whereby, prior to engagement of the first and second fixed suspension means, the cable means is circumferentially offset with respect to the first suspension means in order to provide a slight rotation of the light-carrying structure about the pole during the engagement and disengagement of the first and second suspension means with each other.
Claim 2
Dependent Claim
145 words
A lighting structure comprising: a. a pole; b. a support means carried by the upper end of the pole; c. a light-carrying structure encircling the pole; d. a first fixed suspension means carried by the support means; e. a second fixed suspension means carried by the light-carrying structure whereby the first and second fixed suspension means are interengageable to detachably suspend the light-carrying structure from the support means; and f. cable means extending from the support means to the light-carrying structure for raising and lower the light-carrying structure on the pole whereby, prior to engagement of the first and second fixed suspension means, the cable means is circumferentially offset with respect to the first suspension means in order to provide a slight rotation of the light-carrying structure about the pole during the engagement and disengagement of the first and second suspension means with each other.
Claim 3
Dependent Claim
56 words
The lighting structure of claim 1 wherein: a. the first fixed suspension means includes a plurality of first members circumferentially spaced around the pole and depending vertically downwardly from the support means; and b. the second fixed suspension means includes a plurality of second members projecting from the light structure for interengagement with the first members.
Claim 4
Dependent Claim
41 words
The lighting structure of claim 2 wherein each first member includes a notch and means for guiding its corresponding second member up and into the notch as the light-carrying structure is raised into interengagement of the first and second suspension means.
Claim 5
Dependent Claim
35 words
The lighting structure of claim 3 wherein each first member includes means for guiding its corresponding second member up and out of the notch when the light-carrying structure is being disengaged from the support means.
Claim 6
Dependent Claim
34 words
The lighting structure of claim 3 further including means carried by each of the first members for providing visual indication that the second members are engaged within their corresponding notches in the first members.
Claim 7
Dependent Claim
89 words
The lighting structure of claim 2 wherein: a. the first fixed suspension means includes at least three first members; b. the second fixed suspension means includes at least three second members; c. the cable means includes one support line associated with each pair of interengageable first and second members, wherein each support line extends from the support means to the light-carrying structure; d. each support line is vertically aligned with its associated second member; and e. each support line is circumferentially offset with respect to its associated first member.
Claim 8
Dependent Claim
43 words
The lighting structure of claim 6 wherein the support lines extend from the support means down within the pole to the bottom portion thereof and include detachable means carried by the pole for actuating the lines to raise and lower the light-carrying structure.
Claim 9
Dependent Claim
39 words
The lighting structure of claim 7 wherein the detachable means includes a winch and a pulley assembly whereby the winch includes an attachment cable that passes into the pole and over the pulley for attachment to the support lines.
Claim 10
Dependent Claim
19 words
The lighting structure of claim 8 further including a motor and train of gear wheels for operating the winch.
Claim 11
Dependent Claim
52 words
The lighting structure of claim 9 further including an electrical supply cable at the bottom of the pole and means for selectively connecting the cable to the light-carrying structure in its uppermost position on the pole and to the motor when the light-carrying structure is in its lower-most position on the pole.
