Patent Description:
Filament products can be removed from a reel and stored for later use to protect and maintain the performance of the product. The filament product can include new filaments and/or existing filaments that are going to be left on a reel for any length of time, and subsequently removed and stored. The filament product is typically removed by winding the product directly onto a spool or other similar device to form a coil, or the filament can be wound into a coil without the use of a spool or other device. The coil is tied then stored for later use.

Typically, fly fishing lines are stored and packaged in a loose coil. In some instances, the fishing lines are wound about a storage spool, and the coil remains on the storage spool until later use. To reuse the fishing line, the filament is unwound from the coil or storage spool and re-wound about the reel. When winding the coil about the reel, the coil can be loose and become tangled and/or slippage can occur between the filament and reel.

<CIT> describes a rope reel constructed with connected end frames. <CIT> describes supply reels for holding coils of wire or other like flexible material, and upon which the material may be wound. <CIT> describes a reel with a side wheel or disk which is removable from a core, with the core adjustable and collapsible to permit a coil to be slipped off or on the core when one of the side disks is removed.

The foregoing background discussion is intended solely to aid the reader. It is not intended to limit the innovations described herein. Thus, the foregoing discussion should not be taken to indicate that any particular element of a prior system is unsuitable for use with the innovations described herein, nor is it intended to indicate that any element is essential in implementing the innovations described herein.

The foregoing needs are met, by the spool assembly as claimed in claim <NUM>. The spool assembly includes two flanges, and sliding members that comprise the arbor of the spool. The spool assembly allows a user to create a coil of filament and to remove said coil from the spool for storage. Additionally, the spool assembly can be used to apply tension on the inside of coiled filament for dispensing without slippage or tangling. The sliding members penetrate each flange by extending radially outward, filament cannot slip between the sliding members and flanges.

As will be further explained herein, a first flange orients and allows motion of the sliding members in a radial direction. A second flange adjusts the radial distance of the sliding members from the center of rotation by rotating the second flange relative to the first flange. The second flange can include mating cam profiles and can be removable from the sliding members. A diameter of the arbor (defined by the sliding members), is adjusted by rotating the flanges relative to each other. The second flange can be removed once the sliders have reached their radially innermost position. Detents can be provided on the cam profile of the second flange to create distinct holding points for the sliding members. A biasing force can be applied to the sliding members such that they default to a collapsed position at the minimum (radially innermost position) of their travel. The biasing force forces the sliding members against the cam profile and detents.

An aspect of the present invention provides a spool assembly for supporting a roll of material, according to claim <NUM>. The spool assembly comprises a first flange, a second flange, a first arbor member, a second arbor member, and a biasing member. The first flange defines a first at least one slot, the first at least one slot extending at least partially in a radial direction. The radial direction extends outward from a longitudinal axis of the spool assembly. The second flange defines a second at least one slot that extends at least partially in a transverse direction. The transverse direction being substantially perpendicular to the radial direction and the longitudinal axis. The second flange being rotatably coupled to the first flange such that the first and second flanges rotate relative to one another about the longitudinal axis.

The first arbor member is slidably coupled within the first at least one slot of the first flange and slidably coupled within the second at least one slot of the second flange. The first arbor member is positioned at least partially between the first flange and the second flange. The second arbor member is positioned between the first flange and the second flange, wherein a spacing between the first arbor member and the second arbor member in the radial direction defines an arbor diameter. The biasing member is coupled to the first arbor member such that the first arbor member is biased radially inward toward the longitudinal axis. Rotation of the first flange relative to the second flange causes the first arbor member to translate within the first at least one slot and the second at least one slot causing a change in the arbor diameter.

Another aspect of the present invention provides a method of assembling a spool assembly, according to claim <NUM>. The spool assembly including a first flange, a second flange, and a first arbor member. The first flange defining a first at least one slot, the first at least one slot extending at least partially in a radial direction. The radial direction extending radially outward from a longitudinal axis of the spool assembly. The first arbor member slidably coupled within the first at least one slot. The method comprises: inserting the first arbor member into the first at least one slot defined by the first flange; and coupling a biasing member to the first arbor member such that the first arbor member is biased radially inward toward the longitudinal axis. Whereby rotation of the first flange relative to the second flange causes the first arbor member to translate within the first at least one slot causing a change in an arbor diameter.

This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description section.

The foregoing summary, as well as the following detailed description of illustrative embodiments of the present application, will be better understood when read in conjunction with the appended drawings. For the purposes of illustrating the present application, there are shown in the drawings illustrative embodiments of the disclosure. It should be understood, however, that the application is not limited to the precise arrangements and instrumentalities shown. In the drawings:.

Certain terminology used in this description is for convenience only and is not limiting. The words "axial", "radial", "circumferential", "outward", "inward", "upper," and "lower" designate directions in the drawings to which reference is made. As used herein, the term "substantially" and derivatives thereof, and words of similar import, when used to describe a size, shape, orientation, distance, spatial relationship, or other parameter includes the stated size, shape, orientation, distance, spatial relationship, or other parameter, and can also include a range up to <NUM>% more and up to <NUM>% less than the stated parameter, including <NUM>% more and <NUM>% less, including <NUM>% more and <NUM>% less, including <NUM>% more and <NUM>% less. All ranges disclosed herein are inclusive of the recited endpoint and independently combinable (for example, the range of "from <NUM> grams to <NUM> grams" is inclusive of the endpoints, <NUM> grams and <NUM> grams, and all the intermediate values). The terminology includes the above-listed words, derivatives thereof and words of similar import.

<FIG> illustrate a spool assembly <NUM>, according to an aspect of this disclosure. The spool assembly <NUM> includes a first flange <NUM>, a second flange <NUM>, arbor members <NUM>, and a biasing member <NUM>. The arbor members <NUM> define an arbor <NUM> of the spool assembly <NUM> configured to support a roll or coil of material thereon. The first and second flanges <NUM> and <NUM> of the spool assembly <NUM> can comprise a plastic material, which can be at least semi-rigid to maintain its shape during coiling of a roll of material.

The first and second flanges <NUM> and <NUM> are configured to rotatably couple to one another via the arbor members <NUM>, as further described below. A rotation between the first and second flanges <NUM> and <NUM> can cause the arbor members <NUM> to increase and decrease a diameter size of the arbor <NUM>. For example, rotation of the second flange <NUM> relative to the first flange <NUM> in a first rotational direction can increase the diameter of the arbor <NUM>, and rotation of the second flange <NUM> relative to the first flange in an opposing rotational direction can decrease the diameter of the arbor <NUM>. When the diameter of the arbor <NUM> is decreased (see e.g. <FIG>), the roll of material retained on the arbor <NUM> can be removed. When the diameter of the arbor <NUM> is increased (see e.g. <FIG>), a tension can be applied to the roll of material positioned on the arbor <NUM>. The biasing member <NUM> can be configured to bias the arbor members <NUM> toward a rotational center of the spool assembly <NUM>. (e.g. toward a minimum diameter configuration). The biasing member <NUM> can include a single member coupled to each of the arbor member <NUM>. Alternatively, spool assembly <NUM> can include multiple biasing members <NUM> that are each coupled to a respective arbor member <NUM>.

<FIG> illustrate a spool assembly <NUM>, according to an aspect of this disclosure. It will be appreciated that the spool assembly <NUM> can be transitioned, aligned, and configured in a substantially similar manner as the spool assembly <NUM> described herein. It will be appreciated that spool assembly <NUM> can include configurations and/or components of the spool assembly <NUM>, and vice versa. The spool assembly <NUM> includes a first flange <NUM>, a second flange <NUM>, arbor members <NUM>, and a biasing member (now shown). Each of the first and second flanges <NUM> and <NUM>, the arbor members <NUM>, and the biasing member can be individually formed components that, when assembled together, define the arbor assembly <NUM>. Rotation of the first flange <NUM> relative to the second flange <NUM> about a longitudinal axis L of the spool assembly <NUM> causes the arbor members <NUM> to move and adjust an arbor diameter of the spool assembly <NUM>, as further described herein. In an aspect, the longitudinal axis L extends through a radial center of the spool assembly <NUM>.

<FIG> illustrate views of the first flange <NUM>. The first flange <NUM> includes a first inner surface <NUM>, an opposing first outer surface <NUM>, and a perimeter <NUM>. The perimeter <NUM> is defined by a radially outermost portion extending about the first flange <NUM>, between the first inner and outer surfaces <NUM> and <NUM>. The perimeter <NUM> can be defined by a radially outermost edge of the first inner surface <NUM> and/or a radially outermost edge of the second inner surface <NUM>. In an aspect, the perimeter <NUM> extends circumferentially about the longitudinal axis L. The perimeter <NUM> can include a plurality of ridges <NUM> spaced about the perimeter <NUM>. The ridges <NUM> can facilitate rotation of the first flange <NUM> relative to the second flange <NUM> by providing a grip for a user. The perimeter <NUM> can also include one or more notches <NUM> spaced about the perimeter <NUM>. The notches <NUM> can hold a tie, wire, string, or other coil retaining/tying component to facilitate tying the roll of material after de-coiling the material from a reel onto the spool assembly <NUM>.

The first inner surface <NUM> can include a substantially planar surface. For example, the first inner surface <NUM> located toward the longitudinal axis L of the spool assembly <NUM> and the perimeter <NUM> of the first flange <NUM> can lie on the same plane. Alternatively, the first inner surface <NUM> can be curved. For example, the first inner surface <NUM> located toward the longitudinal axis L can extend radially outward on the same plane up until a planar perimeter location <NUM>. From the planar perimeter location <NUM>, which can extend approximately circumferentially about the longitudinal axis L, the first inner surface <NUM> can curve outward (e.g. bevel) at least partially in a longitudinal direction. The outward curve can define a perimeter portion <NUM> of the first flange <NUM>, which can facilitate winding the roll of material onto and off of the arbor members <NUM>.

The first flange <NUM> defines a first at least one slot <NUM>. The first slot <NUM> extends at least partially in a radial direction R. The radial direction R extends outward from and is substantially perpendicular to the longitudinal axis L of the spool assembly <NUM>. The slot first <NUM> can include one slot, two slots, three slots, four slots, or more than four slots. In an aspect, when more than one slot <NUM> is defined by the first flange <NUM>, each of the first slots <NUM> are spaced equidistantly from each other slot circumferentially about the longitudinal axis L. Additionally, or alternatively, each first slot <NUM> can be spaced radially outward from the longitudinal axis a substantially similar distance as each of the other first slots <NUM>. Additionally, or alternatively, each of the first slots <NUM> can be configured substantially similarly as each of the other first slots <NUM>.

With reference to <FIG>, the first slot <NUM> includes a first edge <NUM> and a second edge <NUM>. The first and second edges <NUM> and <NUM> meet at a first location <NUM> and a second location <NUM>. Between the first and second locations <NUM> and <NUM>, the first and second edges <NUM> and <NUM> are spaced apart from one another to define a first opening <NUM> therebetween. The first opening <NUM> extends from a first end <NUM> of the first slot <NUM> to a second end <NUM> of the first slot <NUM>. The second end <NUM> is spaced radially outward from the first end <NUM> in the radial direction R. In an aspect, the first slot <NUM> can be substantially symmetric when viewed in the radial direction R from the longitudinal axis L. In an aspect, the first slot <NUM> extends substantially linearly in the radial direction R from the first end <NUM> to the second end <NUM>.

The first end <NUM> of the first slot <NUM> defines a first width w<NUM> that extends from the first edge <NUM> to the second edge <NUM>. The second end <NUM> of the first slot <NUM> defines a second width w<NUM> that extends from the first edge <NUM> to the second edge <NUM>. The second width w<NUM> is greater than the first width w<NUM>. The second width w<NUM> is sized to facilitate the insertion and coupling of an arbor member <NUM> to the first flange <NUM>. For example, the arbor member <NUM> can be inserted through the first opening <NUM> at the second end <NUM> of the slot <NUM>. As further described herein, the arbor member <NUM> can translate within the first slot <NUM> between the first end <NUM> and the second end <NUM>.

The first flange <NUM> further defines a first receiving aperture <NUM> and a second receiving aperture <NUM>. The first and second receiving apertures <NUM> and <NUM> extend through the first flange <NUM> from the first inner surface <NUM> to the first outer surface <NUM>. The second receiving aperture <NUM> is spaced radially outward from the longitudinal axis L. In an aspect, the first receiving aperture <NUM> is located at a radial center of the first flange <NUM>. The first receiving aperture <NUM> can extend about the longitudinal axis L. In an aspect, the first and second receiving apertures <NUM> and <NUM> can be sized and/or shaped substantially similarly. The first and second receiving apertures <NUM> and <NUM> are configured to receive a handle <NUM>, as further described below.

<FIG> illustrate views of the second flange <NUM>. The second flange <NUM> includes a second inner surface <NUM>, an opposing second outer surface <NUM>, and a perimeter <NUM>. The perimeter <NUM> can be configured according to at least one of the configurations described above in regard to the perimeter <NUM> of the first flange <NUM>.

The second inner surface <NUM> can include a substantially planar surface. For example, the second inner surface <NUM> located toward the longitudinal axis L of the spool assembly <NUM> and the perimeter <NUM> of the second flange <NUM> can lie on the same plane. Alternatively, the second inner surface <NUM> can be curved. For example, the second inner surface <NUM> located toward the longitudinal axis L can extend radially outward on the same plane up until a planar perimeter location <NUM>. From the planar perimeter location <NUM>, which can extend approximately circumferentially about the longitudinal axis L, the second inner surface <NUM> can curve outward (e.g. bevel) at least partially in the longitudinal direction. The outward curve can define a perimeter portion <NUM> of the second flange <NUM>, which, when coupled to the first flange <NUM>, can facilitate winding the roll of material onto and off of the arbor members <NUM>.

The second flange <NUM> defines a second at least one slot <NUM>. The second slot <NUM> extends at least partially in a transverse direction T. The transverse direction T is substantially perpendicular to the radial direction R and the longitudinal axis L of the spool assembly <NUM>. The second slot <NUM> can include one slot, two slots, three slots, four slots, or more than four slots. In an aspect, when more than one second slot <NUM> is defined by the second flange <NUM>, each of the slots <NUM> are spaced equidistantly from each other slot circumferentially about the longitudinal axis L. Additionally, or alternatively, each slot <NUM> can be spaced radially outward from the longitudinal axis a substantially similar distance as each of the other slots <NUM>. Additionally, or alternatively, each of the slots <NUM> can be configured substantially similarly as each of the other slots <NUM>. In an aspect, the number of first slots <NUM> defined by the first flange <NUM> includes the same number of second slots <NUM> defined by the second flange <NUM>. Each of the first and second slots <NUM> and <NUM> align in the longitudinal direction during rotation of the first and second flanges <NUM> and <NUM> relative to one another.

With reference to <FIG>, the second slot <NUM> includes a first edge <NUM> and a second edge <NUM>. The first and second edges <NUM> and <NUM> meet at a first location <NUM> and a second location <NUM>. Between the first and second locations <NUM> and <NUM>, the first and second edges <NUM> and <NUM> are spaced apart from one another to define a second opening <NUM> therebetween. The second opening <NUM> extends from a first end <NUM> of the slot <NUM> to a second end <NUM> of the slot <NUM>. The second end <NUM> is spaced radially outward from the first end <NUM> in the radial direction R. In an aspect, the slot <NUM> extends in a substantially arcuate shape from the first end <NUM> to the second end <NUM>. In an aspect, the slot <NUM> extends substantially circumferentially about an axis that is parallel to and offset from the longitudinal axis L.

The first end <NUM> of the second slot <NUM> defines a first width y<NUM> that extends from the first edge <NUM> to the second edge <NUM>. The second end <NUM> of the second slot <NUM> defines a second width y<NUM> that extends from the first edge <NUM> to the second edge <NUM>. The second width y<NUM> is less than the first width y<NUM>. The first width y<NUM> is sized to facilitate the insertion and coupling of the arbor member <NUM> to the second flange <NUM>. For example, the arbor member <NUM> can be inserted through the second opening <NUM> at the first end <NUM> of the second slot <NUM>. As further described herein, the arbor member <NUM> can translate within the slot <NUM> between the first end <NUM> and the second end <NUM>.

The second flange <NUM> further defines a third receiving aperture <NUM>. The third receiving aperture <NUM> extends through the second flange <NUM> from the second inner surface <NUM> to the second outer surface <NUM>. In an aspect, the third receiving aperture <NUM> is located at a radial center of the second flange <NUM>. The third receiving aperture <NUM> can extend about the longitudinal axis L. In an aspect, the third receiving aperture <NUM> can be sized and/or shaped substantially similarly to the first and second receiving apertures <NUM> and <NUM> of the first flange <NUM>. The third receiving aperture <NUM> is configured to receive the handle <NUM>, as further described below. It will be appreciated that the second flange <NUM> can include more than one receiving aperture.

The first edge <NUM> of the second slot <NUM> is spaced radially inward from the second edge <NUM> of the second slot <NUM> along a length of the second slot <NUM> from the first end <NUM> to the second end <NUM>. The first edge <NUM> defines a plurality of detents <NUM> positioned between the first and second ends <NUM> and <NUM> of the second slot <NUM>. Each of the plurality of detents <NUM> are configured to releasably prevent the arbor members <NUM> from sliding within the second opening <NUM>, as further described. The plurality of detents <NUM> can include, for example, a series of peaks and valleys long the first edge <NUM>. In an alternative aspect, the detents <NUM> can be located at different locations on either the first flange <NUM> or the section flange <NUM>. For example, the detents <NUM> can be included on surfaces and/or edges on a connection between the first flange <NUM> and the second flange <NUM>. A first axis alignment member <NUM> (see <FIG>) of the first flange <NUM> can couple to a corresponding second axis alignment member <NUM> (see <FIG>) of the second flange <NUM>, as further described below. The first and second axis alignment members <NUM> and <NUM> can include one or more corresponding detents <NUM> therebetween that are configured to releasably prevent rotation between the first and second flanges <NUM> and <NUM>.

The second flange <NUM> further includes the second axis alignment member <NUM>. The second axis alignment member <NUM> extends from second inner surface <NUM> about the longitudinal axis L. The second axis alignment member <NUM> can be configured to align with and/or couple to the corresponding first axis alignment member <NUM> (see <FIG>). The alignment and/or coupling between the first and second axis alignment members <NUM> and <NUM> can facilitate rotation of the first flange <NUM> relative to the second flange <NUM> about the longitudinal axis. In an aspect, each of the first and second axis alignment members <NUM> and <NUM> are formed on the respective first and second flanges <NUM> and <NUM> to form two separate unitary integrated flanges <NUM> and <NUM>. In an alternative, or additional, aspect, the first and second axis alignment members <NUM> and <NUM> can be coupled to the respective first and second flanges <NUM> and <NUM> to form two separate assembled flanges <NUM> and <NUM>. It will be appreciated that fewer or more members can be integrated into the spool assembly <NUM> to rotationally couple the first flange <NUM> to the second flange <NUM>.

<FIG> illustrate different views of the arbor member <NUM>, according to an aspect of this disclosure. The arbor member <NUM> includes a first end <NUM> and an opposing second end <NUM>. The first end <NUM> includes a first retention element <NUM>, and the second end <NUM> includes a second retention element <NUM>. It will be appreciated that the first retention element <NUM> can define the first end <NUM> and/or the second retention element <NUM> can define the second end <NUM>.

The first retention element <NUM> has an outer surface <NUM> that defines a pair of slots <NUM>. The slots <NUM> of the first retention element <NUM> have a first cross-sectional dimension C<NUM> and a second cross-sectional dimension C<NUM>. The second cross-sectional dimension C<NUM> is less than the first cross-sectional dimension C<NUM>. The location of the second cross-sectional dimension C<NUM> is spaced from the location of the first cross-sectional dimension C<NUM> in a direction toward the second end <NUM> of the arbor member <NUM>. The first cross-sectional dimension C<NUM> is greater than the first width w<NUM> of the first end <NUM> of the first slot <NUM>. The first cross-sectional dimension C<NUM> is less than the second width w<NUM> at the second end <NUM> of the first slot <NUM> of the first flange <NUM>. The second cross-sectional dimension C<NUM> of the first retention member <NUM> is less than the first width w<NUM> of the first end <NUM> of the first slot <NUM> of the first flange <NUM>. The configuration of the arbor member <NUM> is such that the first end <NUM> can be inserted into the second end <NUM> of the first slot <NUM> of the first flange <NUM> in a longitudinal direction (e.g. insertion direction). The slots <NUM> of the first retention member <NUM> can be positioned within the first opening <NUM> of the first slot <NUM> of the first flange <NUM>. When the slots <NUM> are positioned within the first opening <NUM>, the arbor member <NUM> can translate between the first end <NUM> and the second end <NUM> of the first slot <NUM>. When the first retention member <NUM> is positioned at the first end <NUM> of the first slot <NUM>, the first retention member <NUM> substantially prevents the arbor member <NUM> from moving away from the first flange <NUM> in a longitudinal direction (e.g. withdrawal direction). When the arbor member <NUM> is positioned within at the second end <NUM> of the first slot <NUM>, the arbor member <NUM> and the first flange <NUM> are free to move away from each other in the longitudinal direction (e.g. withdrawal direction).

In an aspect, the retention member <NUM> and the first slot <NUM> of the first flange <NUM> are configured such that when the retention member <NUM> is positioned within the first slot <NUM>, the arbor member <NUM> is substantially prevented from rotating relative to the first flange <NUM>.

With reference to <FIG>, the second end <NUM> includes the second retention element <NUM>. The second retention element <NUM> has on outer surface <NUM> that defines a pair of slots <NUM>. The slots <NUM> of the second retention element <NUM> have a third cross-sectional dimension C<NUM> and a fourth cross-sectional dimension C<NUM>. The fourth cross-sectional dimension C<NUM> is less than the third cross-sectional dimension C<NUM>. The location of the fourth cross-sectional dimension C<NUM> is spaced from the location of the third cross-sectional dimension C<NUM> in a direction toward the first end <NUM> of the arbor member <NUM>. The third cross-sectional dimension C<NUM> is less than the first width y<NUM> of the first end <NUM> of the second slot <NUM> of the second flange <NUM>. The fourth cross-sectional dimension C<NUM> of the second retention member <NUM> is less than the second width y<NUM> of the second end <NUM> of the second slot <NUM> of the second flange <NUM>. The configuration of the arbor member <NUM> is such that the second end <NUM> can be inserted into the first end <NUM> of the second slot <NUM> of the second flange <NUM> in a longitudinal direction (e.g. insertion direction). The slots <NUM> of the second retention member <NUM> can be positioned within the second opening <NUM> of the second slot <NUM> of the second flange <NUM>. When the slots <NUM> are positioned within the second opening <NUM>, the arbor member <NUM> can translate between the first end <NUM> and the second end <NUM> of the second slot <NUM>. When the second retention member <NUM> is positioned at the first end <NUM> of the second slot <NUM>, the arbor member <NUM> and the first flange <NUM> are free to move away from each other in the longitudinal direction (e.g. withdrawal direction). When the second retention member <NUM> is positioned at the second end <NUM> of the second slot <NUM>, the second retention member <NUM> substantially prevents the arbor member <NUM> from moving away from the second flange <NUM> in a longitudinal direction (e.g. withdrawal direction).

With reference to <FIG>, the arbor member <NUM> can include a biasing member retention element <NUM>. The biasing member retention element <NUM> is configured to receive the biasing member <NUM> thereon. The biasing member <NUM> can be inserted through a retention channel <NUM> and positioned within a retention recess <NUM>. Both of the retention channel <NUM> and the retention recess <NUM> can be defined by a surface <NUM> of the arbor member <NUM>. The retention recess <NUM> can removably retain the biasing member <NUM> within.

It will be appreciated that the number of arbor members <NUM> included in the spool assembly <NUM> can include the same number as there are slots on the first and second flanges <NUM> and <NUM>. For example, if the first flange <NUM> has two first slots <NUM> and the second flange <NUM> has two second slots <NUM>, the spool assembly <NUM> can include two arbor members <NUM>. One arbor member <NUM> inserted into a first slot <NUM> in the first flange <NUM> and a corresponding second slot <NUM> in the second flange <NUM>. The other arbor member <NUM> being inserted into the other first slot <NUM> in the first flange <NUM> and the other corresponding second slot <NUM> in the second flange <NUM>. In an aspect, the spool assembly <NUM> includes the first flange <NUM> having four first slots <NUM> and the second flange <NUM> having four second slots <NUM>. The spool assembly <NUM> can include four arbor members <NUM> positioned within each of the slots of the first and second flanges <NUM> and <NUM> as described above.

With reference to <FIG>, the handle <NUM> includes an insertion end <NUM> and a gripping end <NUM>. The insertion end <NUM> includes a pair of legs <NUM> that extend from a first end <NUM> of the insertion end <NUM> to a second end <NUM> of the insertion end <NUM> in a direction from the gripping end <NUM> toward the insertion end <NUM>. Each leg of the pair of legs <NUM> can include a handle retention element <NUM>. The handle retention element <NUM> can include, for example, a protrusion that extends radially outward from an outer surface <NUM> of the leg <NUM>. In an aspect, the handle retention element <NUM> can provide a snap-fit type connection with the receiving apertures <NUM>, <NUM>, and <NUM> of the respective first and second flanges <NUM> and <NUM> when the handle <NUM> is inserted into the respective aperture. Each leg of the pair of legs <NUM> can radially flex to facilitate insertion into the apertures <NUM>, <NUM>, and <NUM> of the first and second flanges <NUM> and <NUM>. After insertion into the respective aperture <NUM>, <NUM>, and <NUM>, the handle retention elements <NUM> can removably secure the handle <NUM> to the respective flange <NUM> and <NUM>. It will be appreciated that the handle <NUM> could include fewer or more legs <NUM>. For example, the handle can include three, four, five, or more legs <NUM>. In an aspect, the legs <NUM> are spaced circumferentially about the insertion end <NUM> equidistant from each of the other legs <NUM>.

The spool assembly <NUM> can include more than one handle <NUM>. For example, a first handle <NUM> can be coupled to the first receiving aperture <NUM> of the first flange <NUM>, and a second handle <NUM> can be coupled to the third receiving aperture <NUM> of the second flange <NUM>. The legs <NUM> of the handle <NUM> can be configured such that when the first and second handles <NUM> are positioned within the first and third receiving apertures <NUM> and <NUM>, respectively, the legs <NUM> of one handle <NUM> circumferentially intersect the legs <NUM> of the other handle <NUM>. For example, when the handles <NUM> are inserted within the respective first and third receiving apertures <NUM> and <NUM>, the insertion ends <NUM> of each handle <NUM> intersect one another along the longitudinal axis. Each leg <NUM> of each handle <NUM> is positioned circumferentially between corresponding legs <NUM> of the other handle <NUM>. This handle configuration can allow the handles <NUM> to be inserted into the first and second flanges <NUM> and <NUM> along the longitudinal axis L.

The first and second flanges <NUM> and <NUM>, the arbor members <NUM>, the biasing member <NUM>, and the handle <NUM> can each be separate independent components that are assembled together to form the spool assembly <NUM>. A first arbor member <NUM> can be inserted into the first slot <NUM> of the first flange <NUM>. The first arbor member <NUM> can be inserted into the first slot <NUM> through the second end <NUM> until the slots <NUM> of the first arbor member are positioned within the first opening <NUM> of the first slot <NUM>. The first arbor member <NUM> can be slid along the first slot <NUM> to the first end <NUM>. When the first arbor member <NUM> is positioned at the first end <NUM>, the first retention member <NUM> of the first arbor member <NUM> retains the first arbor member <NUM> within the first slot <NUM> such that movement between the first arbor member <NUM> and the first flange <NUM> is substantially prevented in the longitudinal direction.

A second arbor member <NUM> can be inserted into another first slot <NUM> of the first flange <NUM>. The second arbor member <NUM> can be inserted into the other first slot <NUM> through the second end <NUM> until the slots <NUM> of the second arbor member are positioned within the first opening <NUM> of the first slot <NUM>. The second arbor member <NUM> can be slid along the first slot <NUM> to the first end <NUM> to retain the second arbor member <NUM> within the other first slot <NUM>. This process can be repeated for each first slot <NUM> defined by the first flange <NUM>.

After the arbor members <NUM> are positioned within respective first slots <NUM> of the first flange <NUM>, the biasing member <NUM> can be coupled to each of the arbor members <NUM>. For example, the biasing member <NUM> can be inserted through the retention channel <NUM> and positioned within the retention recess <NUM> of each of the arbor members <NUM> that are coupled to the first flange <NUM>. The biasing member <NUM> biases each of the arbor members <NUM> toward the first end <NUM> of each respective first slot <NUM>.

After the biasing member <NUM> is coupled to each arbor member <NUM>, the arbor members <NUM> can be inserted into respective second slots <NUM> of the second flange <NUM>. The arbor members <NUM> can be inserted into the respective second slots <NUM> through the first ends <NUM> until the slots <NUM> of the arbor members <NUM> are positioned within the respective second openings <NUM> of the second slots <NUM>.

After the arbor members <NUM> are positioned within respective first slots <NUM> of the first flange <NUM> and within respective second slots <NUM> of the second flange, the first flange <NUM> can be rotated relative to the second flange <NUM> about the longitudinal axis L. For example, a center of rotation of the first flange <NUM> relative to the second flange <NUM> can lie on the longitudinal axis L. When the arbor members <NUM> are positioned at the respective first ends <NUM> and <NUM> of the first and second slots <NUM> and <NUM>, the arbor members <NUM> define a minimum arbor diameter. As the first flange <NUM> rotates relative to the second flange <NUM>, the arbor members translate (e.g. slide) within the respective first and second slots <NUM> and <NUM> toward the second ends <NUM> and <NUM>. As the arbor members <NUM> translate toward the second ends <NUM> and <NUM>, the arbor diameter increases in size. When the arbor members <NUM> reach the second ends <NUM> and <NUM> of the respective slots <NUM> and <NUM>, a maximum arbor diameter can be achieved. It will be appreciated that when the maximum arbor diameter is achieved, the arbor members <NUM> may be at a location toward the second ends <NUM> and <NUM> of the respective slots <NUM> and <NUM>, as opposed to a location fully at the respective second ends <NUM> and <NUM>.

The detents <NUM> defined by the first edge <NUM> of the second slot <NUM> can removably retain the arbor members <NUM> at a position along the respective slot <NUM>. For example, when the first flange <NUM> is rotated relative to the second flange <NUM> such that the arbor members <NUM> are positioned at a location between the first and second ends <NUM> and <NUM> of the second slot <NUM>, the arbor member <NUM> can contact at least one of the plurality of detents <NUM> to removably retain the arbor member <NUM> at the location between the first and second ends <NUM> and <NUM>. A force provided by the biasing member <NUM> can seat the arbor members <NUM> within the detents <NUM>. To remove the arbor members <NUM> from the respective detents <NUM>, an additional rotational force can be applied (e.g. by a user) to the first and second flanges <NUM> and <NUM> to unseat the arbor members <NUM> from the detents <NUM>.

To disassemble the spool assembly <NUM>, the first flange <NUM> is rotated relative to the second flange <NUM> until the arbor members <NUM> are positioned at the respective first ends <NUM> of the second flange <NUM>. The second flange <NUM> can then be removed from the arbor members <NUM> by moving the second flange <NUM> in a longitudinal direction (e.g. withdrawal direction). After the second flange <NUM> is removed, each of the arbor members <NUM> can be slid within the second ends <NUM> of the respective first slots <NUM>. The arbor members <NUM> can each be removed from the first flange <NUM> by moving the arbor members <NUM> in the longitudinal direction (e.g. withdrawal direction). The biasing member <NUM> can also be removed from each arbor member <NUM>.

During use of the spool assembly <NUM>, the arbor members <NUM> are transitioned toward the second ends <NUM> and <NUM> of the respective first and second slots <NUM> and <NUM> to achieve an increased and/or maximum arbor diameter. A first handle <NUM> can be inserted into the second receiving aperture <NUM> of the first flange <NUM>. A second handle <NUM> can be inserted into the third receiving aperture <NUM> of the second flange <NUM>. A user can then rotate the spool assembly <NUM> about the longitudinal axis L by rotating the first handle <NUM> about the longitudinal axis L. The rotation of the spool assembly <NUM> can wind the roll of material (e.g. filament) about the arbor members <NUM>. After the roll of material is wound about the arbor members <NUM>, the first flange <NUM> can be rotated relative to the second flange <NUM> to slide the arbor members <NUM> toward the respective first ends <NUM> and <NUM> to reduce the arbor diameter. After the arbor diameter is reduced, the second flange <NUM> can be removed from the arbor members <NUM>, and the roll of material can be removed from the spool assembly <NUM>.

To unwind the roll of material onto a reel, the roll of material can be place about the arbor members <NUM> coupled to the first flange <NUM>. The second flange <NUM> can be coupled to the arbor members <NUM> as described above. The first flange <NUM> can be rotated relative to the second flange <NUM> to slide the arbor members <NUM> toward the respective second ends <NUM> and <NUM> to increase the arbor diameter. As the arbor diameter is increased, a tension can be applied to the roll of material by the arbor members <NUM>. A first handle <NUM> can be positioned within the first receiving aperture <NUM> of the first flange and a second handle <NUM> can be positioned within the third receiving aperture <NUM> of the second flange <NUM>. The roll of material can be removed from the spool assembly <NUM> by pulling a strand of the material away from the spool assembly <NUM> causing the first and second flanges <NUM> and <NUM> to rotate and unwind the material. The first and second flanges <NUM> and <NUM> can rotate relative to the first and second handles <NUM> to allow the user to grip the handles while the roll of material is unwinding.

Other components can be used to facilitate the process of winding and unwinding the roll of material. For example, twist ties can be incorporated to tie the roll of material after winding, grasping components can be used to hold or grip the handles <NUM> during winding and unwinding, or still other components can be used.
