Interlocked pay off reel design
An interlocked pay off reel comprises square or rectangular endplates that can be interlocked together to build a wall or skid of reels, and which allows the cable to be unspooled or paid out easily using a simple assembly. The pay off reel comprises two round flanges configured to hold respective ends of a cable spool. The flanges can be snapped to respective two square endplates, which elevate the spool and act as a stable base. The engagement mechanism between the flanges and the endplates permits the spool and flanges to rotate during pay off and applies frictional braking to prevent the spool from back spinning and freewheeling. Handles are built into the endplates so that the reel can be handled and moved easily. Interlock mechanisms on multiple sides and surfaces of the endplates permit the endplates to be locked to other endplates in all directions, allowing stacks of reels to be assembled.
1. A cable reel, comprising:
a flange comprising an engagement hole and a groove configured to hold an end of a cable spool; and
an endplate having a substantially square or rectangular shape,
wherein
the endplate comprises an engagement mechanism on a side of the endplate and comprising flexible pins arranged in a circular formation, and
insertion of the engagement mechanism through the engagement hole causes the engagement pins to hold the flange on the endplate while permitting rotation of the flange about the engagement mechanism.
2. The cable reel of claim 1 , wherein
a wall is formed around the engagement hole,
the flexible pins comprise respective raised ridges on respective outward-facing surfaces of the flexible pins, and
the raised ridges are configured to engage with an edge of the wall while the engagement mechanism is inserted in the engagement hole.
3. The cable reel of claim 2 , wherein
the flexible pins are angled away from a center of the engagement mechanism while in a relaxed state, and
the flexible pins are configured to apply pressure to the wall while the engagement mechanism is inserted in the engagement hole.
4. The cable reel of claim 2 , wherein
the side of the endplate is a first side, and
insertion of a disassembly tool into the engagement mechanism via a second side of the endplate that is opposite the first side causes the raised ridges to disengage from the edge of the wall.
5. The cable reel of claim 4 , wherein
the flexible pins comprise respective tongues that engage with the disassembly tool as the disassembly tool is inserted into the engagement mechanism, and
engagement between the tongues and the disassembly tool causes the flexible pins to retract toward a center of the engagement mechanism.
6. The cable reel of claim 1 , wherein
the endplate further comprises a hook on a first side edge of the endplate,
the hook is configured to engage with a slot on a second side edge of another endplate, and
engagement of the hook with the slot locks the first side edge of the endplate with the second side edge of the other endplate.
7. The cable reel of claim 1 , wherein
the side of the endplate is a first side,
the endplate further comprises an elongated hook on a second side of the endplate that is opposite the first side,
the elongated hook is configured to engage with an elongated receptacle on a third side of another endplate, and
engagement of the elongated hook with the elongated receptacle locks the second side of the endplate with the third side of the other endplate.
8. The cable reel of claim 7 , wherein
the endplate further comprises a first handle on a first top edge of the endplate, and
the endplate maintains a spacing between the first handle and a second handle on a second top edge of the other endplate while the second side of the endplate is locked with the third side of the other endplate.
9. The cable reel of claim 1 , wherein
the endplate further comprises an engagement tab on a top edge of the endplate and a first slot on a bottom edge of the endplate, and
the engagement of the endplate is configured to engage with a second slot on a bottom edge of another endplate.
10. A system, comprising:
a flange comprising a groove configured to hold an end of a cable spool; and
an endplate comprising an engagement mechanism configured to hold the flange and to permit rotation of the flange about the engagement mechanism,
wherein
the endplate has a substantially square or rectangular shape, and
the engagement mechanism comprises flexible pins arranged in a circular formation and configured to engage with an engagement hole formed on the flange.
11. The system of claim 10 , wherein
ridges are formed on respective outward-facing surfaces of the flexible pins, and
the ridges are configured to engage with a wall formed around the engagement hole formed on the flange.
12. The system of claim 11 , wherein
the flexible pins are angled outward from a center of the engagement mechanism while in an unflexed state, and
the flexible pins apply a frictional force against the wall while the flange is held by the engagement mechanism.
13. The system of claim 11 , wherein
the engagement mechanism is formed on a first side of the endplate, and
the engagement mechanism is configured to disengage from the flange in response to insertion of a disassembly tool into the engagement mechanism through a second side of the endplate that is opposite the first side.
14. The system of claim 13 , wherein the insertion of the disassembly tool causes the flexible pins to retract toward a center of the engagement mechanism via interaction between the disassembly tool and tongues formed on the flexible pins.
15. The system of claim 10 , wherein
the endplate is a first endplate,
a hook is formed on a first side edge of the first endplate,
the hook is configured to hook into a slot formed on a second side edge of a second endplate.
16. The system of claim 10 , wherein
the endplate is a first endplate,
an elongated hook is formed on a first side of the endplate that is opposite a second side of the endplate on which the engagement mechanism is formed, and
the elongated hook is configured to hook into an elongated receptacle formed on a third side of a second endplate.
17. The system of claim 16 , wherein
a first handle is formed on a top edge of the first endplate, and
the first endplate maintains a spacing between the first handle and a second handle formed on a top edge of the second endplate while the first endplate and the second endplate are locked together by the elongated hook and the elongated receptacle.
18. A cable reel, comprising:
a first assembly comprising a first flange connected to a first endplate by a first engagement mechanism formed on the first endplate;
a second assembly comprising a second flange connected to a second endplate by a second engagement mechanism formed on the second endplate;
wherein
the first flange and the second flange comprise respective grooves that are configured to hold respective ends of a cable spool,
the first endplate and the second endplate have a substantially square or rectangular shape, and
the first engagement mechanism and the second engagement mechanism comprise flexible pins arranged in a circular formation and configured to engage with a first engagement hole and a second engagement hole of the first flange and the second flange, respectively, and to permit rotation of the first flange and the second flange about the first engagement mechanism and the second engagement mechanism.
19. The cable reel of claim 18 , wherein the first endplate and the second endplate comprise
first engagement hooks on outward-facing surfaces of the first endplate and the second endplate configured to lock the cable reel to another cable reel in a side-to-side direction,
second engagement hooks on side edges of the first endplate and the second endplate configured to lock the cable reel to another cable reel in a front-to-rear direction, and
engagement tabs on top edges of the first endplate and the second endplate configured to lock the cable reel to another cable reel in a top-to-bottom direction.
20. The cable reel of claim 18 , wherein
The first endplate further comprises a hook on a first side edge of the first endplate,
the hook is configured to engage with a slot on a second side edge of a third endplate, and
engagement of the hook with the slot locks the first side edge of the first endplate with the second side edge of the third endplate.
