Description

BACKGROUND

Various structures may be temporarily or permanently joined by twistable wire fasteners, such as loop ties. For example, it is desirable to tie rebar crossings with metal loop ties to hold the rebar in a desired configuration during a concrete pour, for example, so that the rebar maintains the desired configuration in the resulting cured reinforced concrete. Conventional loop ties are twisted manually and require a considerable amount of time and labor. Further, the twisting motion may lead to repetitive stress injuries, such as carpal tunnel syndrome. Also, the most ergonomic or convenient orientation for manual loop tie twisting may leave the ends of such loop ties in an undesirable position. For example, in curing a reinforced concrete slab, some loop ties may inadvertently stick out of the concrete, resulting in an undesirable and potentially dangerous wire fragment from the loop tie extending from the surface of the cured concrete slab.
The present disclosure appreciates that the use of twistable wire fasteners, such as loop ties, may be a challenging endeavor.

DETAILED DESCRIPTION

FIG. 1A illustrates an apparatus 100 for applying a twistable wire fastener 101. Apparatus 100 may include a base member 102. Base member 102 may be configured to be received by a chuck or socket of a rotary tool 103, such as a drill. Apparatus 100 may include a wire-holding member 104. Apparatus 100 may include a shaft 106 extending from base member 102 to wire-holding member 104. Shaft 106 may define an axis of rotation 108 running through base member 102. Wire-holding member 104 may be operatively coupled through shaft 106 to base member 102 such that rotation of base member 102 in the chuck or socket of rotary tool 103 about axis of rotation 108 causes a corresponding rotation of the wire-holding member 104.
In some embodiments, base member 102 may be configured to be received by a chuck or socket of a rotary tool 103. For example, base member 102 may be configured about axis of rotation 108 with one or more of: a circular cross section; a ribbed surface; a polygonal cross section, a socket drive cross section, or a combination thereof. For example, base member 102 may be configured in a ⅜″ hexagonal or octagonal cross-section, e.g., suited for a conventional drill chuck.
In some embodiments, base member 102 and/or shaft 106 may be configured in any desired length to facilitate particular usage applications. For example, base member 102 and/or shaft 106 may be configured to provide a short length for use in tight quarters. In further examples, base member 102 and/or shaft 106 may be configured to provide a longer length for use in locations benefiting from greater reach, for example, an overhead application or applying twistable wire fastener 101 within rebar located in formwork. Base member 102 and/or shaft 106 may be configured to provide a total length of one of 0.5″, 0.75″, 1″, 1.25″, 1.5″, 1.75″, 2″, 2.5″, 3″, 3.5″, 4″, 5″, 6″, 7″, 8″, 9″, 10″, 12″, 15″, 18″, 24″, 30″, 36″, 48″, 60″, 72″, 84″, or 96″, or a range between any two of the preceding values, for example, between about 4″ and about 12″. In some examples, shaft 106 may be configured in any of the preceding values or a or a range between any two of the preceding values.
In several embodiments, wire-holding member 104 may extend from shaft 106 and thence along a curved or angled portion 110 to a tip 112 of wire holding member 104. Curved or angled portion 110 may extend at least in part at an oblique angle to axis of rotation 108 such that wire holding member 104 defines a hook between shaft 106 and tip 112. For example, wire-holding member 104 may be configured in the form of one or more of: a hook, a notched shaft (not shown), a grip(not shown), a clip (not shown), a T-handle (not shown), or a combination thereof (not shown), and the like. For example, wire-holding member 104 may be configured in the form of a curved hook extending from shaft 106 to tip 112. At least a portion of the curved hook may define a decreasing cross section along curved or angled portion 110 in a direction along the hook towards the tip 112, as shown in FIG. 1. In several embodiments (not shown), wire-holding member 104 may be a grip or clip, such as a clamp, locking pliers, and the like.
In several embodiments, the hook defined by wire holding member 104 between shaft 106 and tip 112 may be configured in any desired size to facilitate a usage application. For example, arts and crafts applications may benefit from a relatively small hook, while construction/rebar applications may benefit from a relatively large hook. For example, the hook may be configured to accept twistable wire fasteners 101 having a wire diameter of about 0.05 mm, 0.06 mm, 0.07 mm, 0.08 mm, 0.09 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.25 mm, 1.5 mm, 1.75 mm, 2 mm, 2.5 mm, or 3 mm, or a range between any two of the preceding values, for example, between about 0.1 mm and about 1 mm. In some examples, the hook defined by wire holding member 104 between shaft 106 and tip 112 may define a portion of a circle having an inside diameter in mm of about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 110, 120, 130, 140, 150, 160, 170, 180, 190, or 200, or a range between any two of the preceding values, for example, between about 10 mm and about 100 mm.
In some embodiments, wire-holding member 104 may extend from shaft 106 to a tip 112 of wire holding member 104. At least a portion of wire-holding member 104 between shaft 106 and tip 112 may be configured with one or more of: a circular cross section (not shown); a ribbed surface (not shown); a notched surface (not shown); a polygonal cross section (not shown); a chisel edge (not shown); a cross-section that decreases in cross-sectional area along the portion from shaft 106 towards tip 112; or a combination thereof (not shown). The ribbed surface, for example, may provide a gripping action to the wire-holding member. The notched surface, for example, may provide a notch for wire to be held by the wire-holding member. The polygonal cross-section and/or the chisel edge may provide a cutting function to the wire-holding member. The cross-section that decreases in cross-sectional area along the portion from shaft 106 towards tip 112 may provide, for example, an easier release of wire from the wire-holding member.
FIG. 1B depicts an example embodiment, wherein wire-holding member 104 may be curved to match a portion of one or more objects to be fastened 105 so that apparatus 100 for applying twistable wire fastener 101 may be conveniently hung during application of twistable wire fastener 101. For example, if twistable wire fastener 101 is to be applied to one or more objects to be fastened 105 configured as half-inch diameter rebar, wire holding member 104 may be curved to match the profile of the half-inch rebar. It may be very convenient for a worker applying many twistable wire fasteners 101 in a rebar assembly to be able to temporarily hang apparatus 100, optionally with drill 103, from objects 105 as depicted in FIG. 1B.
FIG. 2A is a flow chart of a method 200 for applying a twistable wire fastener. FIG. 2B is a stepwise sketch of method 200′ for applying a twistable wire fastener 101.
