The present invention relates to a means of storing and dispensing flexible mediums such as cables, cords, tubes, and hoses and straightening the medium both when being stored and when being dispensed.
There are many types of products available for the storage and dispensing of flexible mediums such as cables, cords, tubes, and hoses. However, all these systems have a drawback in that, once stored; only one end of the medium is usefully accessible. For example, an electrical cable has a plug at one end and a socket at the other end. Winding the cable on a reel places one end under multiple windings and results in being able to only access the plug or socket, depending on which is outer-most. It is often necessary only to deploy a short length of cable but the user is forced to unwind the complete cable. Invariably, this leads to a coiled and tangled cable.
Some storage devices have a means of dispensing cable therefrom. However, none of these have the means of dispensing the whole length of the cable. For example, there are spring-loaded extension cables that can be connected to a telephone jack that extend from an end of a housing. However, the cable is not continuous, meaning that each end of the cable can only be drawn for a limited distance, usually half the total length of the cable. There are other devices that have cables coiled around a core. However, the cable can only be extended from one end.
Accordingly, it is an object of the present invention to provide a storing and dispensing system or apparatus that allows for the cable to be stored around the center tube from both ends and also to be dispensed from either end partially or fully.
Some storage devices have a crank attached to a storage reel. This facilitates retrieval but does not straighten the cable.
Accordingly, another object of the present invention is to provide a storing and dispensing system or apparatus that incorporates a means of straightening the cable during the storage and dispensing process.
In accordance with the present invention, the simplest embodiment of the system includes a container that can be of any suitable shape and that is open at both ends with an inner tube with a void between the container and the tube with various methods of supporting the inner tube. This invention allows the cable to be stored on to the inner tube and dispensed from both ends of the container. This allows partial or complete deployment and retrieval of the cable from either end. This invention also encompasses the provision of a means of straightening the cable both during storage and retrieval.
In one embodiment described herein there is provided a system for storing and dispensing cable from both ends of the system comprising: a hollow container; a smaller diameter tube positioned within the container; and a pair of covers at either end of the container for holding the tube within the container while being removable.
In another embodiment of the present invention there is provided a system for storing and dispensing cable from both ends of the system, comprising: a hollow container; a smaller diameter tube positioned within the container; a rotator guide disposed at at least one end of the container and including at least one port through which cable is fed; and a locking mechanism for securing together the container and tube.
In accordance with the present invention there is also provided a system for storing and dispensing cable from both ends of the system, comprising: a hollow container having separate compartments; an opening at the top of each compartment with a collar that rests against a drive pulley; a smaller diameter tube positioned within the container; and a cable guide that is attached to the collar and that rotates as the collar rotates.
The invention description below refers to the accompanying drawings, in which:
For simplicity in connection with the following descriptions, all flexible mediums are referred to as a cable, but it is understood that the same principles also apply to other flexible products such as, but not limited to, cords, tubes, and hoses. A first embodiment of the present invention is illustrated in
The cable can be dispensed partially or wholly by opening one retaining lid at a time and deploying the cable. The closed retaining lid prevents the tube 2 from moving or rotating while the cable is being deployed. Once the cable is stored the container can be used with either lid on the bottom. Normally, the top facing lid is opened to dispense the cable, while the bottom positioned lid is closed. However, with the embodiment shown in
The drawing shown in
A second embodiment of the present invention is shown in
The cable can also be withdrawn from the opposite end 16 by locking the rotator guide at the other end of the assembly.
Another feature of the present invention illustrated in this second embodiment incorporates a removable cable feed attachment 7 that includes an assembly with a pulley 9 and pinch wheel 10. A socket 8 is provided to hold the cable feed attachment 7 to the container 1. This allows the cable feed attachment to be located at either end as required. The cable is placed between the pulley 9 and the pinch wheel 10 (refer to
The cable feed attachment 7 has a bushing 13. An electric drill (not shown) with a driver attachment 14 can be inserted into the bushing 13. The driver attachment 14 can be used to automatically drive the pinch wheel 10 clockwise to deploy the cable and counter-clockwise to retrieve the cable.
A further embodiment of the invention is illustrated in
The container 1, tube 2 and all moving parts of the assembly are fabricated using very low coefficient of friction material such as polypropylene, polyethylene, nylon, teflon, delrin, or other material with low surface friction. While the invention shows surface to surface contact of the various components, it is expected that moving parts could also have ball or roller bearings to further reduce friction. For example, in the second embodiment described herein the rotator guide 5 can have ball bearings where it comes into contact with the container 1 and tube 2.
Reference is now made to a fourth embodiment of the present invention illustrated in
The cable is initially installed by routing it between the pulley 23a and pinch wheel 24a, the center of the collar 26a, the cable guide 25a, around the collars (20a, 20b) into the second container and up to the wire guide 25b, collar 26b and between pulley 23b and pinch wheel 24b.
Refer to
The description below is for one compartment 21a but also applies to the second compartment 21b. The cable is stored in a container as follows: The cable is fed between the pulley 23a, the pinch wheel 24a, and through the center of the collar 26a. The cable is guided to the rim of the tapered insert 37a. Rotating the pulley forces the cable into the collar 26a and via the cable guide 25a to the rim of the insert 37a. The wire guide 25a rotates and arranges the cable around the insert 37a. Because the insert 37a is tapered, the cable falls to the bottom of the compartment.
Dispensing the cable can be accomplished either by pulling the cable out or rotating the pulley (23a, 23b). The wire guide rotates as the cable is dispensed. When all the cable in one compartment has been dispensed, cable from the other compartment is pulled via the rotating collar. As the cable is withdrawn from the second compartment, it uncoils loosely one rotation at a time to the bottom as the insert is tapered. This prevents the cable from seizing. The cable can also be dispensed by removing it from between the pulley and pinch wheel and dispensing it from the container manually. The cable guide rotates to allow for a smooth withdrawal.

This invention can also be used, as described above, in health care facilities such as hospitals, rehabilitation centers, nursing homes, etc. The use of this device can be further enhanced by placing an antibacterial liquid within the container, or passing the cable/tube through the opening that has a disposable anti-bacterial pad or other means of wiping the cable/tube as it passes through.
