12077407
The present disclosure relates to a reusable reel and, more particularly, to a reusable reel for storing and dispensing cable, wire, and the like.
Conventionally, various types of cable, wire, and the like are wound onto reels for storage, shipping, and field use. Typical reels are constructed of wood or plastic that can withstand the stresses of storage and shipping. The weight of the reels adds to the cost of transportation of the cable, wire, or the like that is held on the reel, which increases the cost that must be paid for by the customer or vendor. After the reels are emptied, typically, the reels are then thrown away because the cost of returning them to the supplier for reuse is too high.
Therefore, it may be desirable to provide a reel that is reusable. For example, it may be desirable to provide a reel that can be assembled and disassembled by a technician such that a bundle of cable, wire, or the like can be mounted on the reel in the field. In some aspects, it may be desirable to provide a reel that is configured to receive a reel-less bundle of cable, wire, or the like.
According to an exemplary embodiment of the disclosure, a reusable reel includes a first reel member and a second reel member. The first reel member includes a first barrel portion, a first flange portion, and a first hub portion, and the second reel member includes a second barrel portion, a second flange portion, and a second hub portion.

Referring to
The first reel member 110 includes a barrel portion 120, a flange portion 130, and a hub portion 140. The flange portion 130 extends from a first end 122 of the barrel portion 120 in a plane that is perpendicular to a longitudinal axis X of the barrel portion 120. As illustrated in
The barrel portion 120, the flange portion 130, and the hub portion 140 are portions of a single piece (i.e., monolithic) structure of unitary construction. The flange portion 130 and the inner wall 126 and outer wall 128 of the barrel portion 120 may have a uniform wall thickness that simplifies the molding process by not requiring slides. The flange portion 130 may include radially extending ribs 132 along an outer surface 134 of the flange portion 130 that add strength and durability to the flange portion 130. The barrel portion 120 may include webbing or other strengthening structure 146 between the inner wall 126 and the outer wall 128 at the second end 124.
The hub portion 140 includes a hub wall 144 and a center opening 142 that is configured to be mounted on a support hub (not shown) of a frame (not shown) such that the hub portion 140 can rotate relative to the support hub and frame. The hub wall 144 extends from the inner wall 126 at the first end 122 in a direction toward the second end 124. The hub wall 144 may have a wall thickness that is the same as the wall thickness of the flange portion 130, the inner wall 126, and/or the outer wall 128.
The second reel member 150 includes a barrel portion 160, a flange portion 170, and a hub portion 180. The flange portion 170 extends from a first end 162 of the barrel portion 160 in a plane that is perpendicular to a longitudinal axis X of the barrel portion 160. As illustrated in
The barrel portion 160, the flange portion 170, and the hub portion 180 are portions of a single piece (i.e., monolithic) structure of unitary construction. The flange portion 170 and the inner wall 166 and outer wall 168 of the barrel portion 120 may have a uniform wall thickness that simplifies the molding process by not requiring slides. The flange portion 170 may include radially extending ribs 172 along an outer surface 174 of the flange portion 170 that add strength and durability to the flange portion 170. The barrel portion 160 may include webbing or other strengthening structure 186 between the inner wall 166 and the outer wall 168 at the second end 164.
The hub portion 180 includes a hub wall 184 and a center opening 182 that is configured to be mounted on a support hub (not shown) of a frame (not shown) such that the hub portion 180 can rotate relative to the support hub and frame. The hub wall 184 extends from the inner wall 166 at the first end 162 in a direction toward the second end 164. The hub wall 184 may have a wall thickness that is the same as the wall thickness of the flange portion 170, the inner wall 166, and/or the outer wall 168.
When the barrel portion 120 and the barrel portion 160 are coupled to one another, the center opening 182 may be configured to be aligned with the center opening 142 of the hub portion 150 of the first reel member 110, and the center openings 142, 182 may be configured to receive a single hub or separate hub portions.
The barrel portions 120, 160 are configured such that if a force is applied to the reel 100 in a direction perpendicular or transverse to the X axis (i.e., the radial direction), the inner wall 126 and outer wall 128 of the barrel portion 120 can move toward one another and/or the inner wall 166 and the outer wall 168 of the barrel portion 160 can move toward one another to absorb the force and prevent breakage of the flanges 130, 170 and the hub portions 140, 180. For example, if a technician drops the reel 100 such that a force is applied to the reel in a direction perpendicular or transverse to the X axis (i.e., the radial direction), the inner wall 126 and outer wall 128 of the barrel portion 120 are configured to move toward one another and/or the inner wall 166 and the outer wall 168 of the barrel portion 160 are configured to move toward one another to absorb the force. That is, the inner wall 126 and outer wall 128 of the barrel portion 120 and the inner wall 166 and the outer wall 168 of the barrel portion 160 are compliant (e.g., resilient) to provide a degree of radial compliance when a radial force is applied to the reel 100.
The inner wall 126 of the barrel portion 120 of the first reel member 110 has an inner surface 127 with a plurality of angularly spaced ridges 129 that extend axially from the second end 124 of the barrel portion 120 toward the flange portion 130 at the first end 122 of the barrel portion 120 in a direction parallel to the longitudinal axis X. As illustrated, the inner surface 127 includes six ridges 129, but in some embodiments, the inner surface 127 may include less than or more than six ridges. As illustrated, the six ridges 129 are equally spaced about the periphery of the inner wall 126, but in some aspects, the ridges may be spaced unequally about the periphery to insure a desired alignment between the first reel member 120 and the second reel member 150, as discussed below.
The outer wall 168 of the barrel portion 160 of the second reel member 150 has an outer surface 167 with a plurality of grooves 169 that extend axially from the second end 164 of the barrel portion 160 toward the flange portion 170 at the first end 162 of the barrel portion 160 in a direction parallel to the longitudinal axis X. As illustrated, the outer surface 167 includes six grooves 169, but in some embodiments, the outer surface 167 may include less than or more than six grooves. As illustrated, the six grooves 169 are equally spaced about the periphery of the outer wall 168. The grooves 169 are spaced apart from one another about the periphery of the outer wall 168 by guide portions 165. The guide portions 165 have an arc size that tapers from a middle 163 of the barrel portion 160 toward the second end 164 of the barrel portion 160 in a direction parallel to the longitudinal axis X. As result, a circumferential dimension of the grooves 169 increases from a narrower groove portion 169a that extends from the first end 162 to the middle 163 to an expanding groove portion 169b that extends from the middle 163 toward the second end 164. The guide portions 165 may have a rounded end at the second end of the barrel portion 160 such that the guide portions 165 are configured to guide the ridges 129 into the grooves 169 when the first reel member 110 and the second reel member 150 are being coupled together. It should be appreciated that the guide portions 165 may have any other desired shape that facilitates coupling of the first reel member 110 and the second reel member 150.
The inside diameter of the inner wall 126 of the barrel portion 120 of the first reel member 150 is greater than an outside diameter of the outer wall 168 of the barrel portion 160 of the second reel member 150. The innermost edges 129a of the ridges 129 extending radially inward from the inner surface 127 of the barrel portion 120 define an inside diameter that is less than the outside diameter of the outer wall 168 of the barrel portion 160 of the second reel member 150. The grooves 169 have a radial depth sized to receive the ridges 129 without an interference fit to allow for easy assembly and disassembly. It should be appreciated that, in some embodiments, the grooves 169 may have a radial depth sized to receive the ridges 129 in an interference or friction fit.
The barrel portion 160 of the second reel member 150 may have a length in the direction of longitudinal axis X that is smaller than a length of the barrel portion 120 of the first reel member 110. In such an embodiment, when the barrel portion 160 of the second reel member 150 is inserted into the barrel portion 120 of the first reel member 110, the second end 124 of the barrel portion 120 contacts an inner surface 176 of the flange portion 170 of the second reel member 150 to create a hard stop that signals to a technician that the first reel member 110 and the second reel member 150 are fully coupled together. Also, in such an embodiment, the ridges 129 do not need to extend the entire length from the second end 124 of the barrel portion 120 to the flange portion 130. When the ridges 129 are received in the grooves 169, the first reel member 110 and the second reel member 150 are configured to rotate together with one another to facilitate payout of cable or wire from the reusable reel 100. In some aspects, the ridges 129 and grooves 169 may be eliminated, and the first reel member 110 and the second reel member 150 may therefore rotate independently of one another.
The larger circumferential dimension of the grooves 169 at the second end 164 of the barrel portion 120 makes it easier for a technician to insert the second reel member 150 into the first reel member 110. For example, a technician does not need to line up similarly sized grooves and ridges when coupling the first reel member 110 and the second reel member 150. Instead, regardless of whether the technician lines up the ridges 129 of the first reel member 110 with the narrower portions 169a of the grooves 169 of the second reel member 150, the guide portions 165 will guide the ridges 129 toward the narrower portions 169a of the grooves 169.
In some aspects, the grooves may be spaced unequally about the periphery to insure a desired alignment between the first reel member 120 and the second reel member 150. For example, the unequally spaced ridges and the unequally spaced grooves may be spaced the same about the periphery so that the first reel member 120 and the second reel member 150 are keyed to a particular orientation relative to one another.
In use, a technician places a separately packaged bundle of cable (not shown) on the barrel portion 120 of the first reel member 110. The bundle is not required to have a reel since the bundle will be placed on the reusable reel 100. The barrel portion 160 of the second reel member 150 is inserted into the barrel portion 120 of the first reel member. As discussed above, the technician does not need to align the grooves 169 of the second reel member 150 with the ridges 129 of the first reel member 110 because the guide portions 165 self-align the grooves 169 and ridges 129. The barrel portion 160 second reel member 150 is inserted into the barrel portion 120 of the first reel member 110 until the barrel portion 120 engages the inner surface 176 of the flange portion 170 of the second reel member 150. A first one of the hub portions 140, 180 can then be placed on a support hub of a frame. In some applications, the support hub and frame may be inside of a carrying bag or case. The second of the hub portions 140, 180 can then be placed on the support hub or a separate support hub of a separate frame. The reusable reel 100 can then be rotated relative to the support hub and frame to pay out cable or wire.
