Abstract

Description
A SECURING DEVICE
FIELD OF THE INVENTION
The invention relates to a securing device and more particularly, but not exclusively, to a securing device for a traffic light pole.
BACKGROUND
International patent application number PCT/IB2004/052715 discloses a light assembly which consists of a pole with a plurality of inter-engagable sections. These sections are located end-to-end to form the pole and have co-axial bores so that the pole has a passage therein. A securing cable runs through the passage and extends between the bottom and top sections to secure them together. A light is attached at an operatively upper end of this pole.
These pole sections are generally made of a polymeric material. Creep of polymeric material often occurs and fluctuations in temperature also cause the sections to undergo expansions and contractions. Accordingly, the creep of the material and expansions and contractions of the pole sections, result in changes to the tension in the cable. The cable becomes less effective in that it does not maintain the pole sections securely engaged in their end-to-end relationship.
OBJECT OF THE INVENTION
It is an object of this invention to provide a securing device, which at least partially, alleviates the abovementioned difficulties
SUMMARY OF THE INVENTION
In accordance with this invention there is provided a securing device for a pole comprising - a pole section, and
- a resiliency extendable elongate securing means attached to the pole section and to a support
There is further provided for the support to be a second pole section or a base
A further feature of the invention provides for the resiliency extendable elongate securing means to be a cable and a spring with the spring attached to the cable or to an end of the cable
A yet further feature of the invention provides for the resiliency extendable securing means to be a resiliency extendable cord
A further feature of the invention provides for the pole to be a modular pole made up of a plurality of pole sections and at least part of the securing means to be located in at least some of these pole sections
A yet further feature of the invention provides for the pole to be a pole for supporting traffic lights.
There is further provided for the base to be made of concrete.
These and other features of the invention are described in more detail below.
BRIEF DESCRIPTION OF THE DRAWINGS
One embodiment of the invention is described below, by way of example only, and with reference to the accompanying drawings in which:
Figure 1 is a perspective exploded view of a securing device;
Figure 2 is a perspective view of the device of figure 1 , showing pole sections in broken lines; and
Figure 3 is a cross-sectional side view of the device of figure 1.
DETAILED DESCRIPTION OF THE DRAWINGS
With reference to the drawings, a securing device for a pole is generally indicated by reference numeral 10.
The securing device 10 for a pole 20 consists of pole sections 21 and a resiliency extendable elongate securing means 30 The securing means 30 is attached to one of the pole sections 21 and to a support 40
The pole consists of a plurality of interconnectable pole sections 21 stacked on a concrete base 41 The pole sections 21 are hollow cylindrical and have complementary neck and collar formation 22 at one end and are open at their other end The sections 21 are interconnectable by means of the neck formation 22 fitting into the open end of a subsequent section 21 Each section 21 has a centrally located hole 23 through its neck formation 22 so that a passage runs through the pole 20 in its erected position
The base 41 is in the shape of a solid cylindrical frustum with a central coaxial cylindrical compartment 43 to receive a part of the securing means 30 The support is a metal disc 40 and is bolted on to the concrete base 41 by engaging holes in the base over protruding ends of three L-shaped bolts 42 which are moulded into the concrete 41.
The securing means 30 consists of a resiliency extendable cord 31 attached to a compression coil spring 32 The spring is suspended from the bottom of the support plate 40 so that it is co-axially sunk into the cylindrical compartment 43 A bolt 34 is located co-axially inside the spring with its upper end extending through a central hole in the support plate The lower end of the bolt 34 is secured to a smaller disc 33 The smaller disc 33 is located underneath the spring 32 Nuts (35 and 36) are screwed in at each
end of the bolt above and below the plate and disc (40 and 33). The cord 31 extends between the support disc 40, and a top pole section (not shown) with one end of the cord attached to an upright link formation 37 on the support disc 40 and the other end of the cord 31 secured to an upper pole section (not shown). The link formation 37 is attached to the nut 35 and forms an attachment point for the cord. The bolt 34 is free to move up and down through the central hole of the support plate 40, against or with the bias of the spring 32.
In addition to center hole 39, three co-axial holes 44 are spaced in a triangular formation in the support disc 40. These holes located over compartment 43 when the disc is bolted to the base 41. Three corresponding tubular channels 45 are moulded in the base. These channels 45 extend horisontally between the periphery of the compartment and the periphery of the base to form three passages from outside the base to the compartment. Power supply cables (not shown) are threaded through these passages and holes 44 during installation of a traffic light.
In use, the base 41 is moulded in the ground with the three L-shaped bolts 42 protruding upwardly through an upper surface of the base. The support disc
40 is bolted to the base 41 with the L-shaped bolts 42. One end of the cord 31 is attached to the link formation 37 and the other end is threaded through the pole sections 21 when the pole 20 is erected on the base 41. The cord 31 is attached to a top pole section (not shown) under tension so that the spring is compressed part way from its natural rest position. The spring should not be
compressed all the way so that it allows for further compression, if required due to expansion of the pole sections. Should the pole sections 21 expand due to higher temperatures, the cord tightens and pulls the bolt and disc 33 upwards. In this way the spring 32 is further compressed so that the tension in the cord 31 remains. The opposite is true for lower temperatures and material creep. Once the pole sections crimp or deform under tension, the spring expands in the direction of its rest position to maintain the tension of the cord.
It will be appreciated by those skilled in the art that various alternative embodiments are possible without departing from the scope of the invention. For example, the cord needs not be resiliently extendable and a cable, chain, rope or the like may be used instead.
