NOT KNOWN Spruson Ferguson, Patent Attorneys, Level 33 St Martins Tower, 31 Market Street, Sydney, New South Wales, 2000, Australia Complete Specification for the invention entitled: An Adjustable Coupling The following statement is a full description of this best method of performing it known to me/us invention, including the 5815/2 8 003:357 02/1
I
iR The present invention relates to angularly adjustable couplings to connect tubing or rod.
Couplings which are adapted to connect tubing or rod are generally expensive to manufacture particularly if they are to adjust for the angular inclination of the two pieces of tubing or rod to be connected.
It is the object of the present invention to overcome or substantially ameliorate the above disadvantages.
There is disclosed herein an adjustable coupling to connect two elongated rail members to a post so as to extend generally normal thereto so that said members are angularly adjustable relative to each other about r the longitudinal axis of the post, said coupling comprising a first pair of coupling members, said members being substantially the same configuration, with each member consisting of a concave base and a concave claw portion, said first pair of members being adapted to co-operate with the claw portions and base portions concave toward each other so that said claw portions define a passage through which the post passes, and said base S portions define a passage in which a first one of the elongated members is to be located, a second pair of coupling members, which second pair of coupling members are substantially the same configuration, with each one of the second pair of coupling members consisting of a concave base and a concave claw portion, said second pair of coupling members being adapted to co-operate so that their claw portions and base portions are concave toward each other so that the claw portions thereof define a passage through which the post passes and the base portions define a further passage to receive the other elongated member, fastening means to secure each pair of coupling members together in a clamping manner to engage the post and enlongated members, and wherein the claw portions of the first and second pairs of coupling members co-operate so that said rail members can be arranged with their longitudinal axes generally co-planar.
DG:0860t -2- A preferred form of the present invention will now be described by way of example with reference to the accompanying drawing, which schematically depicts in perspective view an angularly adjustable coupling.
In the accompanying drawing there is schematically depicted an angularly adjustable coupling 10 to secure a pair of tubes 11 and 12 to a vertical post 13. The coupling 10 consists of a first pair of coupling members 14 which secure the tube 12 to the post 13, and a second pair of coupling members 15 which secure the tube 11 to the post 13.
et, The first pair of coupling members 14 each include a base 16 and a JO0 claw portion 17 providing two fingers 18. Each base portion 16 is concave tttt so that the pair of coupling members 14 co-operate to define a passage between the two base portions 16 within which the tube 12 is located. The claw portion 17 is also concave so that the fingers 18 of the pair of coupling members 14 define a passage through which the post 13 passes.
i c 0,1)6 Located between the fingers 18 is a recess 19. Each base portion 16 is provided with an aperture 20 through which a threaded fastener 21 passes #0999* to engage a nut 22 so that the pair of coupling members 14 can be bought into clamping engagement with the tube 12 and post 13.
tIt should be appreciated that the coupling members 14 are of substantially identical configuration.
The pair of coupling members 15 each include a base 23, with each J base 23 being concave so that the bases 23 co-operate to define a passage into which the tube 11 projects. Each coupling member 15 further includes a claw portion 24 which is concave so that the claw portions 24 define a passage within which the tube 13 passes. The claw portions 24 are located within the recesses 19.
Each base portion 23 is provided with an aperture 25 through which a threaded fastener 26 passes to engage a nut 27. The threaded fastener is tensioned so that the coupling members 15 clampingly engage the tube 11 DG:0860t i.Li 3 and post 13.
The above described coupling 10 has the advantage that the tubes 11 and 12 can be adjusted angularly relative to each other. A still further advantage is that the coupling members 14 are substantially identical and the coupling members 15 are also substantially identical, thereby reducing considerably the number of parts that need to be manufactured. Basically only two parts need to be manufactured. This further reduces the cost of stock and ease of stock control problems.

Claims (1)
- 4- -4- The claims defining the invention are as follows: 1. An adjustable coupling to connect two elongated rail members to a post so as to extend generally normal thereto so that said members are angularly adjustable relative to each other about the longitudinal axis of the post, said coupling comprising a first pair )f coupling members, said members being substantially the same configuration, with each member consisting of a concave base and a concave claw portion, said first pair of members being adapted to co-operate with the claw portions and base Sj portions concave toward each other so that said claw portions define a passage through which the post passes, and said base portions define a passage in which a first one of the elongated members is to be located, a second pair of coupling members, which second pair of coupling members are substantially the same configuration, with each one of the second pair of coupling members consisting of a concave base and a concave claw portion, said second pair of coupling members being adapted to co-operate so that their claw portions and base portions are concave toward each other so that t: 4 the claw portions thereof define a passage through which the post passes and the base portions define a further passage to receive the other t tl S elongated member, fastening means to secure each pair of coupling members together in a clamping manner to engage the post and enlongated members, and wherein the claw portions of the first and second pairs of coupling members co-operate so that said rail members can be arranged with their longitudinal axes generally co-planar. 2. The adjustable coupling of Claim 1 wherein the claw portions of said first coupling members, each consist of a pair of spaced fingers between which there is defined a recess within which the claw portions of said second pair of coupling members are received. 3. An adjustable coupling for a fence, substantially as hereinbefore described with reference to the accompanying drawings.
