For example, a base 50 may be coupled to the securement device 51 via adhesive, heat bonding, via fasteners such as rivets, threaded fasteners, etc., by inserting a portion of the securement device 51 through one or more apertures 52, 53, in the base 50, or any other suitable coupling method. Base apertures 52, 53, may be configured in any size and shape. Preferably, one or more base apertures 52, 53, may be elongated in shape, such as to receive a portion of a strap-type of securement device 51. For example, the base 50 may comprise two elongated base apertures 52, 53, which may each receive a portion of a strap-type of securement device 51.
[0036] A base 50 may be coupled to a base shaft 10 via any suitable coupling method. In some embodiments, a base may comprise a shaft aperture 54 which may be sized and shaped to receive a portion of a base shaft 10. A shaft aperture 54 may be configured in any shape and size.

[0046] In some embodiments, the apparatus 100 may comprise one or more channel projections 13, 14, 23, 34, 35. Channel projections 13, 14, 23, 34, 35, may be coupled to one or more arms 11, 21, 31. Channel projections 13, 14, 23, 34, 35, may comprise projections or protrusions that may extend away from the arms 11, 21, 31. Channel projections 13, 14, 23, 34, 35, may be configured in any shape and size. In preferred embodiments, channel projections 13, 14, 23, 34, 35, may comprise a curved surface 13A, 14A, 23A, 34A, 35A, that may extend above or away from the arm 11, 21, 31, that each channel projection 13, 14, 23, 34, 35, is coupled to. Preferably, if an arm 11, 21, 31, has two channel projections 13, 14, 23, 34, 35, positioned on the same side of the arm 11, 21, 31, the curved surfaces 13A, 14A, 23A, 34A, 35A, of the channel projections 13, 14, 23, 34, 35, may be concave curved relative to each other. In some embodiments, the apparatus 100 may comprise one or more tensioner projections 68 which may be coupled to the tensioner block 63, such as to an arm block 64.

Generally, a tensioner knob 60 and a tensioner block 63 may be configured to control the tension of the flexible filament 200 as it moves between the arms 11, 21, 31, towards, and across a proximal guide surface 43 of the guide support 40 so that the flexible filament 200 is not too slack or too tight for the user to add the flexible filament 200 to the working product in a series of stitches. While crocheting, the user will usually wrap the yarn or other flexible filament 200 around their fingers to control how much tension the flexible filament 200 has. Too much tension and the flexible filament 200 will pull the previous stitches apart, too little tension and the needle will not be able to make the appropriate loop or pull.

[0054] In some embodiments, a tensioner block 63 may be movably coupled to the upper arm 31 via a threaded coupler 67, preferably comprising a threaded shaft, a screw, bolt, etc., such that by rotating the threaded coupler 67 in opposing directions the tensioner block 63 may be moved between a block open position 75 and a block closed position 76. In preferred embodiments, the tensioner block 63 may be movably coupled to the upper arm 31 and/or central arm 21 so that the tensioner block 63 may be movable towards one or more of the shafts 10, 20, 30, (e.g., into the block closed position 76) and away from one or more of the shafts 10, 20, 30, (e.g., into the block open position 75).
[0055] In some embodiments, the distal end of the central arm 21 is inserted into the second arm aperture 66 when the tensioner block 63 is in the block closed position 76. Preferably, as the tensioner block 63 is moved into the block closed position 76, an increasing amount of a distal end of an arm 11, 21, 31, such as the distal end 32 of the upper arm 31, may be positioned within the first arm aperture 65, and as the tensioner block 63 is moved into the block open position 75, an decreasing amount of a distal end of an arm 11, 21, 31, such as the distal end 32 of the upper arm 31, may be positioned within the first arm aperture 65. Preferably, as the tensioner block 63 is moved into the block closed position 76, an increasing amount of a distal end of an arm 11, 21, 31, such as the distal end 22 of the central arm 21, may be positioned within the second arm aperture 66, and as the tensioner block 63 is moved into the block open position 75, an decreasing amount of a distal end of an arm 11, 21, 31, such as the distal end 22 of the central arm 21, may be positioned within the second arm aperture 66. In preferred embodiments, the central arm 21 may be maintained in the arm closed position 72 when the distal end 22 of the central arm 21 is inserted into the second arm aperture 66 and when the tensioner block 63 is in the block closed position 76.
[0056] In some embodiments, the central arm 21 may comprise a channel projection 23 and the tensioner block 63 may comprise a tensioner projection 68 (optionally coupled to the arm block 64). When the tensioner block 63 is in the block closed position 76 the tensioner block 63 and its tensioner projection 68 may be positioned relatively closer to the channel projection 23 on the central arm 21, and when the tensioner block 63 is in the block open position 75 the tensioner block 63 and its tensioner projection 68 may be positioned relatively farther from the channel projection 23 on the central arm 21.
[0057] In some embodiments, the apparatus 100 may include a spring 69, such as a coil spring or other type of spring, which may be coupled between two elements, such as the tensioner block 63, a threaded coupler 67, an arm, etc., and so that the spring 69 may tension or bias the tensioner block 63 into one of the block open position 75 and the block closed position 76.
[0058] In use, the apparatus 100 may be configured to receive a flexible filament 200, so that the flexible filament 200 moves through the arms 11, 21, 31, such as in a serpentine manner, and over a proximal guide surface 43 towards a user's crochet hand. In some embodiments, and as shown in
