Application April 30, 1957, Serial No. 655,975

4 Claims. (Cl. 15-119) The object of our present invention is to devise a novel construction and arrangement of the component parts of a mop head whereby the hinge pins serve as the means for securing such parts in assembled and working condition.

A further object of the invention is to devise a novel mop of the extractor type wherein the hinge pins serve several functions; namely, to pivotally support the backing members which carry the absorbent cleaning material, to connect the bearing members to the body portion of the mop, to connect the mop handle with the body portion, and to serve as a mounting for spring mechanism which tends to normally maintain the backing members in horizontal alignment.

A further object of the invention is to devise novel extracting mechanism.

With the foregoing and other objects in view as will hereinafter clearly appear, our invention comprehends a novel mop of the extractor type wherein the hinge means serves to maintain the assembly of the component parts of the mop head.

For the purpose of illustrating the invention, we have shown in the accompany drawings preferred embodiments of it which we have found in practice to give satisfactory and reliable results. It is, however, to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized, and the invention is not limited, except by the scope of the appended claims, to the exact arrangement and organization of these instrumentalities as herein set forth.

Figure 1 is a perspective view of a mop assembly, embodying our invention.

Figure 2 is an exploded view of component parts of the assembly.

Figure 3 is a perspective view showing the parts in extracting position and the manner of limiting the stroke of the extractor handle.

Figure 4 is a section on line 44 of Figure 1.

Figures 5 and 6 are side elevations of other embodiments of the invention showing more particularly the mounting of the extractor handle on the mop handle.

Similar numerals of reference indicate corresponding parts.

Referring to the drawings:

The mop has a body portion 1 of rigid material, such as for example metal or plastic, and is provided with a front depending flange 2 and a rear depending flange 3. The body portion 1 has spaced upwardly deflected portions 4 forming channels open at their bottoms and having at a side a pivot receiving opening 5, adapted to receive the pivot portions of an extractor handle.

Mounted on the body portion is a mop handle socket consisting of a front section 6 and a rear section 7. The front section 6 has a flat base resting on top of the body portion and provided at its forward end with a depending flange 8 which extends over the depending flange 2 of the body portion. The rear socket section has a depending flange 9 which extends over the depending flange 3 of the body portion. 7

Backing members 10 are disposed beneath the body portion with their inner ends in longitudinally spaced relation, with their juxtaposed inner ends deflected as at 11 to adapt them to receive hinge pins 12 which also pass through apertures 13 and 14 in the depending flanges of the body portion and socket sections. The hinge pins as shown are in the form of bolts retained in position by nuts.

Springs 15 encircle the bolts, have one end fixed thereto and the other end bearing against the bottom surface of a backing plate, whereby the tendency of the springs is to move the backing members towards the body portion and retain them in longitudinal alignment and limit their movement in one direction.

The cleaning material carried by the backing members may be of many different types and as shown consists of a block of absorbent material 16 having a flexible strip 17 secured to its top face and also if desired the spaced rigid strips 17'. Studs 18 connected with the flexible strip or the rigid strips pass through apertures 19 in the backing members and a sufficient distance above them to be in the path of an extractor handle 20 to limit its movement during the extracting stroke. The extractor handle is in the form of a fork having its arms terminating in offset pivots 21 to be received in the pivot openings 5 of the body portion.

A mop handle 22 is secured in the handle socket by a fastening device 23.

In Figure 5, we have shown an embodiment of mounting a manually actuated extractor handle on the mop handle. A handle 24 has arms pivoted at 25 to the mop handle and the free ends of the arms are pivotally connected with a link 26 so that a forward push on the handle 24 will advance the handle 20 to cause the backing members to be folded towards each other to eifect the extracting operation.

In Figure 6, a forked handle 27 is pivotally mounted at 28 on the mop handle 22 and pivotally connected with a link 28' which in turn is pivotally connected with the loop of handle 20, so that when the handle 27 is pulled rearwardly the backing members will be pressed towards each other.

The arms of the extractor handle preferably have cone shaped bearing members 29 loosely mounted on them and cooperate with ramps 30 on the backing members 10.

It will be apparent from the foregoing description that the hinge pins 12 carry the backing plates and springs, pass through the body portion and handle socket sections and serve as the sole means for securing and retaining them in operative relationship as an assembled unit.

The construction and arrangement of the component parts and the manner of assembly materially reduces the cost of construction of such parts and their assembly into a unit of assembly.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:

1. A mop head assembly, comprising a body portion having a front and a rear depending flange, backing members disposed beneath said body portion and having their inner ends spaced from each other, a handle socket having sections having depending flanges overhanging the front and rear flanges of the body portion, hinge pins on which the inner ends of the backing members are pivotally mounted, said hinge pins passing through said body portion flanges and socket section flanges and serving as the sole means of maintaining the assembly of said backing members, body portion and handle socket sections, and an absorbent compressible block of cleaning material secured to said backing members.

2. The construction defined in claim 1, wherein springs are mounted on the hinge pins having one end fixed to its pin with its other end bearing against the bottom surface of its respective backing member and tend to maintain said backing members in longitudinal alignment.

3. A mop assembly, comprising a body portion having a front and a rear depending flange, a handle socket having a front section with a depending flange to overlie the front depending flange of the body portion and having a rear section with a depending flange overlying the rear depending flange of the body portion, backing members disposed beneath said body portion and having their inner ends spaced from each other, hinge pins on which said backing members are pivo-tally mounted, said hinge pins passing through said depending flanges and being fixed thereto, whereby said hinge pins serve as the means for maintaining the assembly as a unit of said backing members, body portion and handle socket sections, a handle, fastening means to secure the sections and handle together, and an absorbent compressible cleaning material carried by said backing members.

4. A mop head assembly, comprising a body portion having upwardly deflected portions forming channels open at their bottoms, an extractor member pivoted in side Walls of said channels, a sectional handle socket, a mop handle fixed to said sections, said body portion and sections having overlapping front and rear flanges, backing members below said body portion having their inner ends spaced from each other, bolts on Which the backing members are pivotally mounted, said bolts being fixed to said overlapping portions of the handle socket sections and body portion, springs encircling said bolts, each of said springs having one end fixed to the bolt and the other end bearing against its respective backing member and tending to move them towards said body portion, and absorbent compressible cleaning material secured to said backing members.
