Abstract
A portable windguard for use on a pipe to shield a weld being applied from wind comprising a collar, means for attaching and securing the collar t o the pipe and a shield extending generally perpendicularly from the collar. T he shield can be collapsible, hence readily transportable from site to site.</S DOAB>
Description
2 FIELD OF THE INVENTION
3 The present invention relates to a portable structure and more
4 particularly to an easily erected, temporary, collapsible windguard for use on a pipeline when a welder is making a weld.
8 It is important that an environment is provided, for a welder fabricating 9 or repairing a pipeline, that is shielded from the wind in order to prevent the wind from pushing the molten metal away from the desired location when 11 doing a weld.
12 Traditionally, a windboard has been used to shield a welding site on a 13 pipeline from the wind. A typical windboard comprises a square piece of 14 plywood with semicircular cut-outs of different sizes, formed along the margin of the board to accommodate different diameter pipe. The board is held 16 upright from the pipe with the cut-out fitting around it.
17 One problem with the windboard, however, is that it is awkward for the 18 welder to transport from site to site. Further, the windboard is not attachable 19 to the pipe and therefore it is necessary for a second person to hold the windboard in place while the welder welds the pipe.
21 One object of the invention is to provide a windguard that is easily and 22 reversibly attachable to a portion of pipe.
23 Another object of the invention is to provide a windguard that is 24 adjustable to accommodate a wide range of diameter pipes, typically 2 to 24 inches in diameter.
1 Another object of the invention is to provide a windguard that is 2 collapsible, hence easily transportable from site to site.
In one broadly stated aspect of the invention, a welder's windguard is 6 provided comprising:
7 = a collar having means for disengagably securing the collar around a 8 pipe; and 9 = a shield attached to the collar and extending angularly therefrom so that it assumes an upright or generally radial position when the 11 collar is mounted to the pipe.
12 In a preferred embodiment of the invention, a welder's windguard is 13 provided comprising:
14 = a longitudinally split collar having two free ends and further having an adjustable securing means for securing the collar around a pipe;
16 = a collapsible shield for extending angularly out from the collar; and 17 = the shield having a plurality of spaced apart stiffeners attached to 18 the collar and extending radially and substantially perpendicularly 19 from the collar for supporting the shield.
In a more preferred embodiment, the shield is made from a flexible, 21 fire-retardant material such as canvas and the stiffeners are L-shaped rods.
22 One leg of the rod runs along the collar and the other leg extends across the 23 shield. The former leg is rotatably attached to the collar so that the windguard 24 can be folded much like an accordion.
2 Figure 1 is a perspective view of the windguard in its extended 3 configuration, secured around a pipe.
4 Figure 2 is a front view of the windguard showing the adjustable securing means.
6 Figure 3 is a side view of the windguard showing the right angle 7 configuration of the stiffeners.
Having reference to the Figures 1, 2 and 3, the windguard 1 comprises 11 a collar 2, means 3 for clamping and securing the collar 2 around a pipe 4, 12 and a shield 5 projecting angularly from the collar 2.
13 The collar 2 and shield 5 are formed of non-flammable canvas.
14 Therefore they are readily flexible.
The collar 2 is a sleeve, split longitudinally, so that its two free ends 2a, 16 2b can be fitted around the pipe 4. The two free ends 2a, 2b can overlap to 17 adjust the collar 2 to the outside diameter of the pipe. The shield 5 has a hem 18 15 at its end furthest away from the collar 2.
19 A plurality of spaced apart stiffeners 6 extend along the collar 2 and across the shield 5. Each stiffener 6 is a metal rod of right angle configuration 21 having first and second legs 7,8. The first leg 7 is rotatably secured to the 22 collar 2 by inserting it into a pocket 9 that is located on the collar 2.
The 23 second leg 8 is inserted into the hem 15 and further secured to the shield

4 Figure 2 is a front view of the windguard showing the adjustable securing means.
6 Figure 3 is a side view of the windguard showing the right angle 7 configuration of the stiffeners.
Having reference to the Figures 1, 2 and 3, the windguard 1 comprises 11 a collar 2, means 3 for clamping and securing the collar 2 around a pipe 4, 12 and a shield 5 projecting angularly from the collar 2.
13 The collar 2 and shield 5 are formed of non-flammable canvas.
14 Therefore they are readily flexible.
The collar 2 is a sleeve, split longitudinally, so that its two free ends 2a, 16 2b can be fitted around the pipe 4. The two free ends 2a, 2b can overlap to 17 adjust the collar 2 to the outside diameter of the pipe. The shield 5 has a hem 18 15 at its end furthest away from the collar 2.
19 A plurality of spaced apart stiffeners 6 extend along the collar 2 and across the shield 5. Each stiffener 6 is a metal rod of right angle configuration 21 having first and second legs 7,8. The first leg 7 is rotatably secured to the 22 collar 2 by inserting it into a pocket 9 that is located on the collar 2.
The 23 second leg 8 is inserted into the hem 15 and further secured to the shield
5 by 24 a fastening means such as glue 14. The stiffeners function to hold the shield 5 generally upright relative to the collar 2 when the latter is secured around 1 the pipe 4. They also function to stretch the shield 5 into an extended 2 configuration, much like a fan.
3 The means 3 for clamping and securing the collar 2 around the pipe 4 4 comprises a VelcroTM loop section 10 attached to the outside of the collar 2, said velcro loop section 10 essentially extending the entire length of the collar
3 The means 3 for clamping and securing the collar 2 around the pipe 4 4 comprises a VelcroTM loop section 10 attached to the outside of the collar 2, said velcro loop section 10 essentially extending the entire length of the collar
6 2. Attached to one end of the collar 2 is an elastic strip 11. Attached to the
7 elastic strip 11 is a strap 12 having a VelcroTM hook fibre section 13 which is
8 of a sufficient length so that when the collar 2 is wrapped around the pipe 4,
9 the strap 12 will also wrap around the pipe 4. The VelcroT"" hook fibre section 12 then comes in contact with the VelcroTM loop section 10 thereby clamping 11 and securing the windguard 1 to the pipe 4. The elastic strip 11 ensures that 12 the windguard 1 is snugly secured to the pipe 4 by providing tension.
