Electrical Appliance Cord Storage

The present invention relates to an arrangement for storing an electrical cord, switch and plug inside the handle of a vacuum cleaner and is an improvement over conventional cord storage arrangement.

The present invention employs a resiliently self-coiling electrical cord, which actually facilitates the handling and operation of the appliance.

More particularly, according to the present invention a cord storage arrangement for an electrical appliance comprises a resiliently self-coiling insulated electrical conductor cord and a tubular electrical appliance handle defining therein an elongate hollow cord storage space dimensioned to receive the cord within the handle with the cord in a coiled inoperative stored condition within the storage space. A plug is electrically connected to one end of the cord for connecting the cord to an electrical current supply on stretching of the cord into an operative condition in which the cord extends from the handle. The cord is provided with a switch and a plug which can be screwed in threaded engagement with the upper end of the handle, through which the cord extends in its operative condition.

Only a small part of this coiled electrical cord will be laying on the floor while using the vacuum cleaner, minimizing thus this inconvenience. Also the fact that the coiled electrical cord comes out of the upper end of the handle of the vacuum cleaner makes it much easier to control it while operating the appliance.

The interior space of the handle of a vacuum cleaner is really the ideal place for storing the electrical cord, switch and plug, and pulling out or pushing in the coiled electrical cord can be done very easily and fast.

Also screwing and unscrewing the electrical switch and plug on the top end of the handle is a very simple operation.

The attractiveness of this method is highlighted by the fact that nothing of the stored components is visible except the closing cap on the top end of the handle which is in fact a part of the specially designed electrical plug.

The present invention does not require a major change in the construction of the vacuum cleaner and the new components are simple in design, easy to manufacture and can readily be adapted and incorporated in existing upright vacuum cleaner models.

FIG. 1 is a view of the upper end and part of the lower section of the handle of a stored vacuum cleaner for storing the electrical cord, switch and plug.

FIG. 2 is a cutaway view of the upper end and part of the lower section of the handle of a vacuum cleaner, while the appliance is not in use.

FIG. 3 is a cutaway view of the upper end of the handle of a vacuum cleaner while the appliance is in use.

Reference is made to FIG. 1 wherein the handle 1 of a vacuum cleaner is shown, after an electrical cord 6, 8, a switch and a plug 4 have been stored inside handle 1. Nothing of said stored components is visible except the top of the electrical plug 4 which serves as a closing cap for an elongate hollow cord storage space comprising the interior of the handle 1. A plastic grip 2 and the top of said electrical plug 4 can be made out of the same material, having the same finish and the same color, so that both together are part of the same grip design. The simplicity and attractiveness of this new cord storage arrangement is in sharp contrast with the conventional cord storage arrangements.

In FIG. 2 the front half of the tubular handle 1 and grip 2 have been cutaway in order to be able to show the coiled electrical cord 6 and 8, and the electrical switch 7 which is specially designed, stored inside the tubular space in handle 1; the specially designed electrical plug 4 is shown screwed on top of handle 1 and serves as a closing cap of the storing space. A threaded ring 3 is installed and secured to the top end of handle 1, so that said specially designed plug 4 can be screwed on top of handle 1, after the coiled electrical cord 6, 8 and switch 7 have been pushed inside said handle 1. The use of a coiled electrical cord 6, 8, which is of the resiliently self-coiling type, is dictated by the shape of the narrow tubular cord storage space inside handle 1. A 14 foot coiled electrical cord can easily be stored inside the handle of a regular upright type vacuum cleaner. It is of course possible to store a longer coiled electrical cord by using a cord with a smaller diameter or / and a vacuum cleaner handle with a larger diameter.

At the upper end of said coiled electrical cord 6, there is a rigid segment 5, approximatively 1" long which connects cord 6 to plug 4 and which can pivot inside said plug 4. When plug 4 is used as a closing cap and screwed on top of handle 1, said rigid segment 5 will be in a position parallel with the prongs of plug 4. The coiled electrical cord 8, smaller than coiled electrical cord 6, is always inside handle 1 of the vacuum cleaner and connects the electrical switch 7 to the electrical motor of the appliance.

Referring to FIG. 3 there is shown in section the upper end of handle 1 of a vacuum cleaner, the treaded ring 3, secured to the top end of handle 1 and the plastic grip 2, covering both the end of handle 1 and the threaded ring 3. The other components shown in this view are the coiled electrical cord 6 which has been completely pulled out of the storing space inside said handle 1; the coiled electrical cord 8 connecting the electrical switch 7 to the motor of the appliance and which is completely extended inside the tubular storing space; the threaded electrical switch 7 which is screwed in the threaded ring 3 at the top end of handle 1 and closes the storing space; electrical plug 4 which has been plugged in electrical outlet 9 and the rigid pivoting segment 5 which is now in a perpendicular position to the prongs of plug 4.

Although the descriptions and specific details above given are associated with a vacuum cleaner, it is to be understood that this new electrical cord storage arrangement can also be used in floor polishers and other applicances and tools. It is also to be understood that the descriptions and specific details above given, are not a limitation of this method, but may be modified within the scope of the appended claims.
