extension 42 projecting from thefirst end 34 of the body 31. The at least oneextension 42 terminates at a distal end and may form a portion of the internal throughbore 40. An extension outer surface 31A generally aligns with the outer surface 31A of the body 31. The at least oneextension 42 may have a cross section similarly shaped to the cross section of the body 31. The cross section of the at least oneextension 42 may be the full cross section of the body 31 or may only make up a portion. It is to be understood that the at least oneextension 42 may be formed integral with the body 31 or may be a component that is assembled to the body 31. The body 31 and the at least oneextension 42 may be made from any material suited to withstand tensile, compressive and/or impact forces along and traverse to thelongitudinal axis 32 and may provide sufficient wear and chemical resistance. Typical materials include but are not limited to plastics, e.g. acrylonitrile butadiene styrene (ABS), nylon, polyether ether ketone (PEEK) or polyethylene terephthalate (PET). Typical materials may include metals, e.g. steel, aluminum, cast iron, powdered metal. Typical processes used to manufacture the body 31 and the at least oneextension 42 may include but are not limited to: machining, casting, sintering, forging, injection molding or additive manufacturing. The body 31 and the at least oneextension 42 may be the virgin color of the material used or may be altered either by dyeing, painting or anodizing. - The L-shaped
bracket 50 includes afirst leg 52 having a top surface, a bottom surface, a first edge, a second edge, a third edge and a fourth edge. The first edge and the second edge are essentially parallel. The third edge and the forth edge are essentially parallel with the first edge and the third edge being traverse to each other. Thefirst leg 52 forms acenterline 54 running essentially parallel to and disposed between the first edge and the second edge. Thefirst leg 52 further includes a mountinghole 56. Anarcuate slot 58 is formed from thetop surface 52 to thebottom surface 54 and is arranged to be essentially concentric with the mountinghole 56. At least one mountingpoint 60 may be provided at an end opposite to the end having the mountinghole 56 andarcuate slot 58 and generally extends from the top surface to the bottom surface. The at least one mountingpoint 60 may be of any shape or size suitable for mounting devices, e.g. sensors. The at least one mountingpoint 60 is shown as a circular opening having a diametric size of 0.315″-1.18″ for English devices and 8 mm-30 mm for SI devices. - The L-shaped
bracket 50 may also include asecond leg 62 extends away from a portion of the second edge of thefirst leg 52. As shown, thesecond leg 62 extends away from the second edge and aligns with the top surface, the bottom surface and the third edge. Thesecond leg 62 is arranged at an angle α to the bottom surface and is shown as being approximately 90°. However, it is to be understood that the angle α may be of any angle in relation to the bottom surface. Thesecond leg 62 may be formed integral with thefirst leg 52 or may be an additional component added to the second member. Thefirst leg 52 and thesecond leg 62 may be made from any material suited to withstand tensile, compressive and/or impact forces along and traverse to thecenterline 54 and may provide sufficient wear and chemical resistance. Typical materials include but are not limited to plastics, e.g. acrylonitrile butadiene styrene (ABS), nylon, polyether ether ketone (PEEK) or polyethylene terephthalate (PET). Typical materials may include metals, e.g. steel, aluminum, cast iron, powdered metal, sheet metal. Typical processes used to manufacture thefirst leg 52 and thesecond leg 62 may include but are not limited to: machining, casting, sintering, forging, injection molding, additive manufacturing, stamping, or laser cutting. Thefirst leg 52 and thesecond leg 62 may be the virgin color of the material used or may be altered either by dyeing, painting or anodizing. - At least one mounting
point 60 may be provided and generally extends from the top surface to the bottom surface. The at least one mountingpoint 60 may be of any shape or size suitable for mounting devices, e.g. sensors. The at least one mountingpoint 60 is shown as a circular opening having a diametric size of 0.315″-1.18″ for English devices and 8 mm-30 mm for SI devices. - The
centerline 54 and thelongitudinal axis 32 form a first angle ϕ between when thefirst leg 52 is attached to apivot point 64 near the distal end of the at least oneextension 42. The first angle ϕ as shown is at approximately 90°. Thepivot point 64 is shown as a socket head cap screw passing through an opening (not shown) in thefirst leg 52 and threading into a threaded hole (not shown) on the at least oneextension 42. It is to be understood that thepivot point 64 may be made of any configuration suitable for allowing thefirst leg 52 to pivot about the body 31 through the first angle ϕ, e.g. fastener, pin or bearing. As shown, thearcuate slot 58 provides approximately 180° of angular displacement. In other words, thecenterline 54 of thefirst leg 52 may pivot approximately 180° relative to thelongitudinal axis 32 of thecylindrical member 30. It should be understood that the allowable angular displacement may larger or smaller than 180° and is controlled in part by the length of thearcuate slot 58. - The
pivoting locking member 66 aligns with thearcuate slot 58 and is configured to prevent, hinder or allow pivoting between thecylindrical member 30 and thefirst leg 52. As shown, thepivoting locking member 66 is a button head cap screw that threads into a threaded hole (not shown) on the at least oneextension 42. Pivoting is prevented by tightening the button head cap screw into the threaded hole whereby the bottom surface of thefirst leg 52 is clamped with a clamp force to the at least oneextension 42. Partially loosening the button head cap screw releases a portion of the clamp force and allows thefirst leg 52 to pivot with restriction through the first angle ϕ relative to thelongitudinal axis 32 of thecylindrical member 30. Fully loosening the button head cap screw releases the clamp force and allows thefirst leg 52 to pivot through the first angle ϕ relative to thelongitudinal axis 32 of thecylindrical member 30. It should be understood that the surfaces of the at least oneextension 42 and thebottom surface 54 of thefirst leg 52 may be rough or smooth to hinder or facilitate pivoting. It should also be understood that the surfaces of the at least oneextension 42 and the bottom surface of thefirst leg 52 may be provided with a plurality of ridges (not shown) for predetermined pivoting increments, for instance, 5° increments through the first angle ϕ. Furthermore, there may be materials added between the surfaces of the at least oneextension 42 and thebottom surface 54 offirst leg 52 to hinder or facilitate pivoting. For instance, a washer made of rubber to hinder pivoting or made of polyoxymethylene to facilitate pivoting. While thepivoting locking member 66 has been described with a button head cap screw, it should be understood that other methods of preventing, hindering or allowing pivoting may be used, such as a wave washer installed under the button head cap screw, a clamping lever, clamping screw, c-clamp, or a magnet. It should also be understood that preceding features may be available for configurations where the top surface is assembled to the at least oneextension 42. It should be further noted that thepivot point 64 may work with thepivoting locking member 66 wherein thepivoting locking member 66 and thepivot point 64 require unclamping prior to pivoting of thefirst leg 52 relative to thecylindrical member 30. Thepivot point 64 may also be provided with a friction device to prevent, hinder or allow pivoting between thefirst leg 52 relative to thecylindrical member 30. - The anchoring
device 68 may take the form of a cable tie, e.g. wire tire, hose tie or zip tie, that may be configured to attach to thepivot point 64 at one end and at an opposite end, bind cables, lines or any other type of link that has been passed through the internal through bore 40 to thesensor 20. Additionally, the anchoringdevice 68 may cooperate with thepivoting locking member 66 to act as a hard stop when pivoting thefirst leg 52 relative to thecylindrical member 30. The anchoringdevice 68 may also be used as a reference point against reference marks on thefirst leg 52 to allow repeatable placement of thesensor 20 after any movement of the articulatingsensor bracket assembly 10. - Referring now to
