Abstract
A holder to maintain elongated flexible materials in a coiled orientation, has at least one coil support assembly. Each coil support assembly has a first support and a second support. At least one roller is supported by the first support. The second support is positioned in spaced linear relation to the first support. The first support and the second support are capable of relative linear movement toward each other and away from each other. At least one roller is supported by the second support. A linear stop limits movement of the first support and the second support away from each other. A retraction mechanism biases the first support and the second support away from each other.
Description
- There is described a holder that will hold video cable, electrical cord, air hose, Ethernet cable, multi conductor cable and the like in a continuous coiled orientation, will permit the line to be pulled out for use and will retract the line back onto the holder after use.
- Holders are used to hold a line of rope, electrical cord, hose, and numerous other elongated flexible materials in a coiled orientation. A retraction mechanism is used to draw the line back onto the holder after use. The retraction mechanism, typically, consists of a rotating drum. When the drum rotates in a first direction line is fed from the drum and when the drum rotates in a second direction line is fed back onto the drum. The drum is spring biased to rotate in the second direction to feed line back onto the drum. U.S. Pat. No. 5,535,960 (Skowronski et al) entitled “Cord Reel Assembly” is an example of such a retraction mechanism.
- There is described a holder to maintain elongated flexible materials in a coiled orientation, which is believed to have a novel construction. The holder has at least one coil support assembly. Each coil support assembly has a first support and a second support. At least one roller is supported by the first support. The second support is positioned in spaced linear relation to the first support. The first support and the second support are capable of relative linear movement toward each other and away from each other. At least one roller is supported by the second support. A linear stop limits movement of the first support and the second support away from each other. A retraction mechanism biases the first support and the second support away from each other.
- The above described holder retracts in a manner which is much different than a rotating drum. The amount of line that the holder can accommodate depends upon a distance between the first support and the second support, multiplied by the number of coils the holder is capable of supporting. It is preferred that the rollers be capable of supporting more than one coil. When a force is exerted upon the line, the first support and the second support move together and, in doing so, create slack which enables the line to feed out. Conversely, retraction is based upon travel by the first support and the second support back to their original positions away from each other taking up the slack and drawings the line back onto the holder, This will be mathematically demonstrated in examples which will be hereinafter provided.
- In contrast to the drum type hose or cord reels this mechanism does not apply a torque that twists the input end of the hose or cord. In a conventional reel it is necessary to have slip rings (electrical) or o-rings (fluid) to prevent a twisting failure when the hose or cord is wound and unwound. With this mechanism there is no twisting of the flexible hose or cord.
- A significant benefit of this cord reel arrangement when used with electrical cords, Audio Cable, Ethernet cable, hoses, and other multi conductor cords is that there is no cutting or rewiring required that would adversely affect existing electrical certifications and/or breech the integrity of the circuit or path. This cord reel arrangement can support any length, gauge or number of conductors continuously, An extension cord, Audio Cable, Ethernet cable, hoses, and other multi conductor cords of a desired length can be purchased and inserted into the cord reel. When that extension cord becomes damaged or worn, it can be removed from the cord reel and a new continuous elongated flexible material inserted,
- If a single coil support assembly is capable of holding six or seven feet of coiled line, a greater length of line can be accommodated by merely providing more than one coil support assembly so that, in combination, the desired greater length is accommodated.
- It is preferred, but not essential, that the one or more coil support assembly be encased within a housing.
- There will hereafter be described a retraction mechanism that is in the form of a telescopically extendible cylinder having a retracted position and an extended position. It will be appreciated that any device capable of linear movement and having an outward bias into the extended position may be utilized. The telescopically extendible cylinder may be biased by a mechanical spring, an air spring or other biasing device that biased the telescopically extendible cylinder into the extended position.
- It is preferred that the first support and the second support each have inner stops that engage the other of the first support or the second support and outer curved cod supporting surfaces with more than one roller positioned at spaced intervals along the outer curved surface. This enables each coil to be supported by rollers which define a curved surface.
- These and other features will become more apparent from the following description in which reference is made to the appended drawings, the drawings are for the purpose of illustration only and are not intended to be in any way limiting, wherein:
-

Multiplecoil support assemblies 12 may be used in conjunction with each other. in this embodiment three support assemblies 12 a, 12 b and 12 c are shown working in conjunction with each other. Coil support assemblies 12 a, 12 b and 12 c each have afirst support second support 16 a 16 b and 16 c in spaced linear relation to each other, Outer curved coil supporting surfaces on first supports 14 a, 14 b and 14 c and second supports 16 a, 16 b and 16 c haverollers 18 capable of supporting more than one coil of elongated flexible material 11 (FIG. 7 ). First supports 14 a, 14 b and 14 c and second supports 16 a, 16 b and 16 c are capable of relative linear movement toward each other and away from each other. Alinear stop 20 limits movement of first supports 14 a, 14 b and 14 c and second supports 16 a, 16 b and 16 c away from each other and aretraction mechanism 22 biases first supports 14 a, 14 b and 140 and second supports 16 a, 16 b and 16 c away from each other.Retraction mechanism 22 is a telescopicallyextendible cylinder 26 that has a retracted position and an extended position and is biased by a mechanical orair spring 28 to the extended position.Inner stop surfaces 30 on first supports 14 a, 14 b and 14 c and second supports 16 a, 1 6 b and 16 c engage each other whenretraction mechanism 22 is in the retracted position. Coil support assemblies 12 a, 12 h and 12 c may be encased together within ahousing 24.Housing 24 has aninlet 36 and anoutlet 38 through whichflexible materials 11 may enter and exithousing 24.Housing 24 may be used primarily for aesthetic purposes, but may also act to protect the various components ofcoil assemblies 12 and prevent interference withflexible materials 11. As will be understood fromFIGS. 5 and 6 , the location ofinlet 36 andoutlet 38 may vary depending on design preferences or constraints. - Referring to
