ADJUSTABLE MOP HEAD Filed April 5, 1962 IN VEN TOR. team/A120 /(IKA$/ United States Patent O 3,115,657 ADJUSTABLE MOP HEAD Leonhard Kikas, 83-15 169th St, Jamaica, N.Y. Filed Apr. 3, 1962, Ser. No. 184,905 2 Claims. (Cl. 15150) This invention relates generally to mops and more specifically to mop heads located at the end of mop handles.

It is an object of the present invention to provide a mop head located at one end of a mop handle for detachably holding a mop thereto, the head being adjustable.

Another object of the present invention is to provide a mop head wherein adjustment may be conveniently and quickly accomplished.

Still another object of the present invention is to provide an adjustable mop head wherein adjustment may be made relative to the longitudinal axis of the mop handle.

Other objects of the present invention are to provide an adjustable mop head bearing the above objects in mind which is of simple construction, has a minimum number of parts, is inexpensive to manufacture and efiicient in operation and use.

For other objects and for a better understanding of the invention reference may be had to the following detailed description taken in conjunction with the accompanying drawing, in which:

FIGURE 1 is perspective view of the present invention;

FIG. 2 is a side elevational view thereof shown in opened position; and

FIG. 3 is a cross sectional view taken along the lines 3-3 of FIG. 2 and looking in the direction of the arrows thereof.

Referring now to the drawing in detail, the numeral represents an adjustable mop head according to the present invention wherein there is a sleeve element 11 that fits over one end of -a mop handle 12. At one end of the sleeve 11 is a flattened portion 13. An opening 14 extends transversely through the flattened portion 13 and an arcuate solt 15 radially defined about the opening 14 also extends though the flattened portion. A pair of

jaw elements

16 and 17 are attached pivotally free on a pin 18 which is fixed in the opening 14 of the flattened portion of the sleeve. The lower jaw element 17 is comprised of a generally long transverse channel 19, the forward edge of which is inclined reanwardly to form a hook 2t).

Extending longitudinally rearward from the center of the channel 19 are a pair of parallel arms 21, each having an opening 22 near its rear end through which the pin 18 extends. At a point between the extreme ends of each of the arms 21 there is an opening 23 extending transversely through the arms, the openings being in alignment with each other. A bolt 24 extends through the openings 23 and the slot 15, the bolt 24 having an enlarged head 25 at :one end thereof and a threaded portion 26 at its opposite end. A wing nut 27 is threadedly engaged upon the bolt 24, as shown in FIG. 3 of the drawing. A platform 28 is located between the arms 21., as shown in FIGS. 1 and 2 of the drawing. The jaw element 16 is comprised of generally long, transversely extending channel 29 which corresponds in configuration to the channel in the lower jaw. Channel 29 has a forward edge which is rearwardly inclined to form a hook 30 which cooperates with the hook to grasp a mop element therebetween.

From the midportion of the channel 29 are a pair of rearwardly extending arms 31 which are parallel to each other and which are provided near their rearmost ends with transversely extending openings 32 through which 3,115,657 Patented Dec. 31, 1963 the pin 18 extends. A platform 33 is located between the arms, as shown in FIG. 2 of the drawing. A tension coil spring 34 is afiixed at each of its ends to one of the

platforms

33 and 28, the tension spring 34 exerting a squeezing pressure between the jaw elements to grip a mop element therebet'ween. A rearwardly extending handle 35 is afiixed to the upper side of the platform 33, the handle having a convenient sleeve 36 at its extreme rearward end, made of rubber, plastic or the like for being easily grasped in the hand to spread the jaw elements to release the mop element.

In operation, the mop head may be readily adjusted by simply loosening the thumb nut 27 and moving the lower jaw element pivotally to the angle desired, after which the Wing, or thumb nut may be tightened again. Thus, adjustment is made possible of the mop head relative to the mop handle. -It is under-stood that the mop element, not shown in the drawing, is grasped between the channel shaped jaws, being detachably held therewithin.

While various changes may be made in the detail construction, it shall be understood that such changes shall be Within the spirit and scope of the present invention as defined by the appended claims.

What I claim as new and desire to protect by Letters Patent of the United States is:

1. In an adjustable mop head the combination of a sleeve, said sleeve adapted to receive one end of a mop handle, a pair of jaw elements pivotably mounted upon said sleeve for movement towards and away from each other, said jaw elements comprising an upper and a lower jaw element, adjustable means for selectively affixing said lower jaw relative to said sleeve, tension spring means acting between said jaw elements biasing said jaws toward each other, said upper jaw element having an upstanding handle, said handle extending rearwardly, said upper and lower jaw elements being provided with generally long opposed transverse channels, the open sides of which face inwardly, the forward edge of each of said channels having a rearwardly extending angular hook and a pair of longitudinlly extending parallel arms afiixed to the center of each of said channels, a pin carried by said sleeve pivotally supporting said arms of said upper and lower jaw elements providing said pivotal mounting thereof, said jaw elements being pivotally afiixed near the rear ends of said arms to a flattened portion of said sleeve, said adjustable means comprising an arcuate opening in said sleeve radially defined about the pivot of said jaw element arms, corresponding openings in each arm of said lower jaw, said openings being in alignment with said arcuate slot and a bolt extending through said openings and said arcuate slot, said bolt having a wing nut threadedly coupled thereto.

2. In an adjustable mop head the combination as set forth in claim 1 wherein said tension spring means comprises a coil spring and each of the said jaw elements includes a platform and afiixed to each platform is one end of said coil spring.
