In the use of electric irons to press clothes and fabrics the power cord leading from the electrical outlet to the iron frequently impedes the work of the operator by its annoying tendency to lay across the clothes during ironing thereby wrinkling the clothes and interfering with the free movement of the iron. This condition makes the operators task much more difficult and timeconsuming since it requires the operator to manipulate an additional object, i.e., the cord. More importantly, the cord creates a safety hazard in that the insulation surrounding the electric conductors may be damaged by contact with the hot iron and fabrics which are being ironed may be burned while the operator is manipulating the cord.

Electric iron cord retractors have been designed in the past to eliminate the aforementioned problems, but they are inconvenient to use. One general type of prior art retractor employs the force of a spring for placing the cord in tension when the operator pulls on the iron. The retracting tension is produced either by a coiled torsional spring, as in Davis US. Pat. No. 2,270,997, or

alternatively by placing a spring in tension by bending. A major drawback of such retractors is that the tension on the cord increases with the degree to which the spring is twisted or bent, as the case may be. Thus the operator must exert a greater force on the iron when the cord is more fully extended than when the cord is extended very little. In addition, when the cord is extended substantially and the iron is set upright temporarily, as is necessary to manipulate the fabric being pressed, the greater spring force tends to pull the iron off balance.

Some retractors have been designed which use a pulleyweight system, thereby providing constant tension on the cord regardless of its degree of extension, but other problems are encountered with these devices. In some cases, as shown for example in the'LaPastora U.S. Pat. No. 3,250,030, Howard US. Pat. No. 1,522,684 and Robinson U.S. Pat No. 2,680,789, the iron cord is not held high enough above the pressing surface and thus tends to catch on bulky fabrics and wrinkle the clothing during the ironing process. In other cases, such as in Aab US. Pat. No. 2,444,800 and Corbliss US. Pat. No. 2,471,312, the pulley mechanism permits inadequate transverse angular movement of the cord hampering operation of the retractor when the iron is not manipulated directly in front of the pulley. Also too much space is frequently taken up on the-surface of the ironing board by the retracting devices or their attaching clamps, as is the case for example particularly with the Aab, Corbliss and LaPastora devices.

Another problem which arises with such prior art cord retractors is that storage of the ironing board and retractor is difficult. In some cases it is inconvenient to remove the cord from the retractor. In other cases the retractor must be detached and stored separately from the ironing board. As a consequence of the above drawbacks, previous iron cord retractors have generally been inconvenient to use.

SUMMARY OF THE PRESENT INVENTION The present invention overcomes the aforementioned deficiencies of previous electric iron cord retractors by utilizing a pulley-weight retractor system which is designed for maximum convenience to the operator. A pulley which has an open top is provided so that the cord may easily be placed upon it and thereafter removed when the ironing is finished. A pair of high side flanges prevent the cord from falling off the pulley when in use. The pulley is attached to the top of a retractor arm so as to swivel about the longitudinal axis of the arm, the arm being long enough to hold the pulley high and away from the top of the ironing surface when the arm is in its vertical operative position. The bottom of the arm attaches in either of two positions to a special clamp which is fastened by a doublesided adhesive, or alternatively by screws, solely to the underside of the ironing suface. In one position the clamp holds the arm and pulley mechanism operatively upright at the end of the ironing board. In the second position the clamp holds the arm parallel to and beneath the ironing surface for storage. Cord tension is provided by a weight which conveniently attaches to the cord at a location above the floor between the pulley mechanism and the source of electricity, normally a household outlet.

The pulley-weight system provides a constant tension on the cord which is sufficient to retract the cord promptly as necessary while the iron is moved about but insufficient to causethe iron to topple over when set upright temporarily regardless of the placement of the iron. The arm simultaneously holds the cord out of contact with the ironing surface. Smooth lateral movement of the iron and cord is permitted by the swivel attachment between the pulley and the arm without hampering the operation of the retractor. The entire retractor attaches completely to the underside of the ironing board, thereby eliminating any obstruction on the ironing surface, and the cord is easily attachable or removable from the pulley system. Finally, the retractor provides a second position so that the arm and pulley system may be stored conveniently with the ironing board.

It is therefore a principal objective of the present invention to provide a novel and improved apparatus for conveniently retracting an electric iron cord.

It is a further principal objective of the present invention to provide such a retractor having a pulley-weight mechanism which puts constant tension on the iron cord and holds the cord high and away from the ironing surface while facilitating full lateral movement of the iron and cord.

It is a further objective of the invention to provide a retractor mechanism which attaches entirely to the underside of the ironing surface.

It is a still further objective of the invention to provide a second position of the retractor mechanism for convenient storage of the mechanism along with the ironing board.

The foregoing and other objectives, features, and advantages of the invention will be more readily understood upon consideration of the following detailed description of the invention, taken in conjunction with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT With reference to FIG. 1, the cord retractor mechanism generally indicated as 10 is secured to the end of the ironing board 12 on the underside of the ironing surface 14 by a clamp mechanism 16 which is attached to the ironing board by a doublesided adhesive 18 as shown in FIG. 3. (If the board 12 is constructed of wood rather than metal as shown, it may be desirable to use screws or bolts forfastening the clamp rather than an adhesive.) This mounting arrangement leaves the ironing surface of the board 12 entirely free and unobstructed. An electric iron cord 20, supplying electricity to an iron 22, rests upon a pulley 24 and is held in tension by a weight 26 attached to the cord at a location above the floor between the pulley 24 and a household electrical outlet 28. The weight 26, under the influence of gravity, exerts a constant force on cord 20 thus keeping the cord in constant tension regardless of the position of iron 22.

The pulley 24 is equipped with a pair of high side flanges 30 (preferably at least 1 inch above the pulley axis) as shown in FIG. 4 for retaining the cord on the pulley, and is mounted by a swivel 32 for lateral pivoting atop a vertical arm 34. The arm 34 has a rearward bend 36 at the bottom, for permitting the free vertical drop of the cord 20, and is attached to an elongate square support member 38 which fits in the clamp mechanism 16 and is secured by a tightening knob 40.

Referring to FIG. 2, the body of the clamp mechanism 16 consists of a block 42 made of acrylic plastic, metal or other suitable material. A square aperture 44 passes from the middle of one side of the block through its center to the opposite side, such aperture being sized so as to slidably accept the member 38 in a loose mating fit. A second identical square aperture 46 passes through the block at right angles to aperture 44, the two intersecting at the center of the block. A knob 40 is attached to a threaded rod 48 which screws into the block 42 at the intersection of the two apertures.

The square member 38 may be inserted interchangeably in either

aperture

44 or 46 and secured by turning knob 40 so that the end of the threaded rod 48 presses against the member 38. This permits the retractor mechanism to fit either into the upright operating position or alternatively in the storage position beneath and parallel to the ironing surface as illustrated in phantom in FIG. 2. It should be noted that since most metal ironing boards contain a downwardly projectingv peripheral flange such as 50, it is necessary that the distance between the top of the

apertures

44, 46 and the top of the block 42 be sufficient to permit the square support member 38 to clear the bottom of the flange 50 when the retractor is in its operative position.

An exemplary metal weight 26 with tabs 52 which can be bent tightly around the cord 20 for securing the weight to the cord is shown in FIG. 5. preferably the weight comprises approximately three ounces of lead pre-formed in the shape as shown for facility in clamping the weight to the cord in the manner depicted in FIG. 6. The weight should be placed so as to remain between the pulley and the floor through all extremes of movement of the iron 22.

When the iron cord retractor 10 is in its upright operating position, the cord 20 rests on the pulley 24 and rides freely over it. Since the use of the retractor l0 probably prevents the cord from reaching a normal household outlet, the addition of an extension cord 54 will very likely be necessary. As the operator moves the iron 22 away from the retractor 10 while ironing fabric, the cord 20 glides over the pulley 24 pulling the weight 26 up. Similarly, as the operator moves the iron toward the retractor the weight 26 pulls the cord down, taking up slack. The vertical arm 34 continually holds the cord far above the ironing surface. If the operator moves the iron from side to side, the pulley 24 pivots laterally on the swivel 32 permitting the cord 20 also to move easily from side to side while the side flanges 30 prevent the cord from falling off the pulley 24. When the operator is finished, the cord 20 simply lifts off the pulley 24 and the retractor 10 may be placed in its storage position. In this manner the components operate harmoniously to keep the electric power cord from hindering the iron operator and provide a convenient means of storing the retractor along with the ironing board.
