FIG. 3 is an elevational, section view of the structure shown in FIG. 1, taken along the line 33 thereof, and looking in ,thedirection of the arrows.
FIG. 4 is a fragmentary, exploded perspective view showing a pair of mop head attachment cups and a portion of the mop carrier member.
DESCRIPTION OF THE PREFERRED EMBODIMENTv Referring now to the drawings, and in particular to FIGS. 1 and 2, the numeral 9 generally indicates a mop head carrier member on which is operatively mounted 0 a mop head generally indicated by the numeral 12. The
carrier member 9 includes an upper elongated rigid portion 8 which may be made from any suitable material as, for example,'from an elongated, rectangularly shaped layer of wood. The carrier member 9 also includes an elongated rectangularly shaped lower cushion portion 11 which is attached to the'lower surface of the rigid portion 8 by any suitable adhesive. The cushion portion 11 maybe made from any suitable elastic material as, for example, a suitable rubber or a suitable foam plastic material. As illustrated in FIGS. 3, and 4, a suitable cushion or bumper 10 is mounted around the periphery of the carrier member rigid portion 8. The bumper 10 may be made from any suitable elastic material as, for example, a suitable rubber or foam plastic material which is adhered to the outer periphery of the rigid portion 8 by any suitable means, as by a suitable adhesive.
As shown in FIGS. 1 and 2, the dust mop is provided with a mop handle 14 which has its lower end threadably attached to a handle attachment means generally indicated by the numeral 13. As shown in FIG. 2, the handle attachment means 13 includes a tube or sleeve 15 which has a threaded bore in its upper end that threadably receives the lower end of the handle 14. A pair of spaced apart legs 16 are integrally mounted on the lower end of the sleeve 15 and they are disposed on the opposite sidesof an attachment tongue 18 and they are pivotally connected to the tongue 18 by a suitable rivet 17. The attachement tongue 18 is integrally formed on the upper end of an attachment plate 19 which is formed integral with an attachment tube 20.
The attachment plate 19 is swivelly attached to the.
carrier member 9 by the following described structure. An elongated horizontal pivot rod 21 is carried by the tube 20 and it extends through suitable apertures in a pair of upstanding ears 23 of a suitable U-shaped attachment clip means which has an elongated longitudinally disposed body portion 24. The apertured ears 23 are integrally formed at the ends of the body portion 24. The U-shaped attachment clip means is disposed in an elongated longitudinal concave recess 26 which is formed in the upper surface of the rigid carrier portion 8 and is secured in place by a pair of suitable screws 25.
The pivot rod 21 is provided with a suitable head 22 on one end thereof and with a lock nut 27 on the other end thereof. A plastic washer 28 is mounted around the pivot rod 21 at each end of the attachment plate 19. It will be seen that by adjusting the lock nut 27, a controlled degree of swivel tension can be provided. The swivel tension can thus be adjustedto the individual users preference.
The mop head 12 includes a mop element 29 which is made from a suitable material as, for example, a cot- The mop element 29 is secured to a mop element backing material 30 by any suitable adhesive in the usual manner. The backing material 30 may be of any suitable material, as for example, a non-woven cloth material. One suitable non-woven fiber cloth material is an unwoven polypropylene fiber cloth material.
The mop element backing material 30 includes an extension 31 along either side thereof, and said extensions 31 function as attachment flaps. The attachment flaps 31 are brought upwardly around the sides of the carrier member 9 and they are then folded over the top thereof and are secured to the carrier member 9 by the following described means.
As shown in FIG. 4, each end of the carrier member rigid portion 8 is provided with a pair of vertical holes or seats 32 in each of which is press fitted a retainer cup 33. Each retainer cup 33 includes a cylindrical body 34 and an integral top wall 35 in which is formeda pair of cross slits 36. The cups 33 are made from a flexible plastic or any other suitable flexible material so that the portions of the cup wall between the slits 36 are flexible, whereby the attachment flaps 31 may be quickly and easily secured to the carrier member 9 by pressing the attachment flap portion overlaying each cup downwardly into the slits 36 to form an inwardly extended loop 37 as shown in FIG. 3. The portions of the cup wall 35 between the slits 36 then spring upward and hold the attachment flaps 31 in place.
It will be seen that the dust mop of the present invention provides a structure wherein the mop head 12 may be easily attached in place on the carrier 9, and be removed therefrom in a quicker and more efficient manner than the prior art type mop structures which include tie straps or snaps or other means of attaching the mop head to a carrier frame of some sort. The disposable mop element of the present invention is adapted to be used in the same manner as the prior art mops. However, it will be seen that the disposable mop element 12 of the present invention is a labor saving device and is economical, since for hosptial use it does not need recleaning, treating, and sterilizing for further use. The mop element of the present invention is economical to make and accordingly, it may be used only once and then disposed of. The mop element 12 of the present invention may be sold in a sealed bag to prevent contamination ofthe treated mop during shipment and storage before it is used.
While it will be apparent that the preferred embodiment of the invention herein disclosed is well calculated to fulfill the objects above stated, it will be appreciated that the invention is susceptible to modification, variation and change.
