' 1 This invention relates to a mop structure. The invention is particularly useful in connection with a dust mop, and similar mops. In the handling of mops, such as, for example, a dust mop, it is dimcult to keep the mophead properly positioned upon the floor, with the nose or forwar portion of the mop tightly engaging the floor so that it may be directed readily into corners and places difiicult of access. If spring means are'employed in conjunction with the handle for exerting pressure against the top of the mop, the resulting structure allows lateral play and the mophead is difficult to control because of such lateral play.
An object of the present invention is to provide a mophead structure in which a resilient body is employed to integrate the parts of the head into a, firm and easily controlled body, while at the same time providing a resilient connection between the handle and the head for efiecting accurate control thereof. Yet, another object is to provide a mophead and handle connection therefor in-which a resilient member joins the head to the'handle, the resilient member, however, later- 10 Claims. (Cl. 15-147) ally engaging the walls of the head so as to permit y relatively high flexibility, and then sharply reducing such flexibility after a predetermined limit of sweep is reached. A still further object i to provide a-resilient integrator device employed as a central portion of a mophead for uniting the parts of the head firmly and rigidly in the central structure, while providing a flexible connection between the central structure and a mop handle. A still further object is to provide a resilient mophead structure in which mop-holding prongs are embedded, th prongs extending at a spaced relation from themophead, and the head being provided with a handle-receiving socket resiliently connected to the structure in which such prongs are embedded. Other specific objects and advantages will appear as the specification proceeds.
The invention is illustrated, in a single embodiment, by the accompanying drawings, in Which- Figure 1 is a perspectiv view of a mop structure embodying my invention; Fig. 2, a top plan view of the structure on a reduced scale; Fig, 3, an enlarged transverse sectional view, the section being taken as indicated at line 3-3 of Fig. 2; Fig. 4, a longitudinal sectional view, the sec-'- tion being taken as indicated at line 4-4 of Fig. 2;

In the illustration given, iii designates a central resilient body formed of rubber, or any other suitable r silient material. The body I9 has the general shape of a shield, and is provided along its sides and front portion with a recess I l adapted to receive a plate l2. The plate l2 has an inner downwardly-flanged end, which is tightly received within the recess I I of the resilient block it. The block NJ has, also embedded therein metal prongs l3, which extend outwardly around th plate 52 a spaced distance and terminat near the forward end of the plate in slightly spaced-apart relation. Upon the free ends Id of the prongs are drawn the sleeve memberldto which strands i6, forming the mop body, are secured. The outer end of the plate I2 is preferably turned downwardly and outwardly at I! so as to provide a support for the inner surface of the taped sleeve l5.
The resilient body It is slitted fromits rear side inwardly a substantial distance at spaced which is integrally formed. ahandle socket 2t.
With the structure shown, it will be noted that the tops of the sides 21 of the neck member [9 engage the inner sides of the body l8 so that lateral movement of the flexible neck I9 is restricted, thus giving effective control of the lateral movements of the mophead.
The socket portion it is provided with an opening 22 adapted to receive a mop handle. The opening 22 may be circular in shape or, if desired, elliptic in shape, depending upon the type of handle which is to be employed.
The neck l9, as illustrated more clearly in Figs.
' the point illustrated in Fig. 5, and at that point,
where the top edges of the material meet each other, thus bridging the tops of the slots, further upward movement is-less easy. Thus-after the handle 24 has been .raisedto the position indicated in Fig. 5, furtherraising of the handlewill impose much greater pressure upon the forward portion of the mophead. It will be understood that such slots may be of any desired number and location, and the shape of the slotsmay be varied depending upon the material used and the desired pressure which it is desired to place upon the nose or forward portion of the mop.
Operation In the operation of the mop, the mop handle is placed within the socket 22, which is preferably slightly smaller than the handle so that the handle is tightly held within the socket. The handle is then raised, the slots 23 permitting an easy movement up to the point at which the mopping operation is conveniently carried on. At this point, the upper slots are bridged over, as illustrated in Fig. 5, and further elevation of the mop places greater pressure upon the mophead. The mophead may be moved back and forth while the neck flexes readily. The relatively wide neck Hi, which engages the adjacent walls of the resilient member (0, enables the mophead to be guided laterally without play between the parts, while at the same time permitting easy flexing in the connection between the handle socket and the resilient body. When released, the resilience of the neck 19 brings the handle 24 into horizontal alignment with the body l0, and the mop may be stored in this position. Even if the mop should be stored in a closet resting upon the nose of the head, the resilience of the neck It maintains the handle 24 in alignment with the head.
The resilient body Hi forms a firm integrating structure by which the mophead parts are united, while at the same time permitting the slight yielding of such parts under blows, collisions, etc. The result is that the structure is cushioned by its center against violent blows against objects engaged by the mophead so that, by reason of such resilience and the padded sleeve 55 of the mop, no damage Or injury is done to such ob jects. At the same time, the operator has com plete control of the mophead and is able to move it accurately into dimcult corners, the resilient neck I9 holding the nose of the mop downwardly against the floor as it enters such corners, etc.
In forming the central resilient body it, the prongs I3 may be placed in position within the mold and the molded body cast in the form illustrated. In the resulting structure, the prongs i3 provide a rigid frame extending along the walls iii of the recess and causing the flexing joint between the handle socket and the body iii to occur in the forward portion of the body iii, thus directing pressure exerted by the raising of the handle against the forward portion of the mophead.
The positioning of the prongs 13 along the recess further maintains such walls in true alignment and facilitates the easy swinging of the neck i9 between such rubber-covered prongs.
The plate [2 is preferably formed of metal, plastic, or other suitable rigid material, and the inner edge of the plate provides a frame which looks the edge portions of the resilient body against flexing whereby the flexing of the structure is concentrated within the forward portion of body in where it is most effective for the purposes above described.
In the modification illustrated in Fig. 7, the mop body 25 is formed in its entirety of rubber or other resilient mold material and is equipped with a single piece metal-retaining member 25 embedded in the body 25. A fabric sheath 2! is received about the retaining member 26. If de sired, the outer edge of the rubber body 25 may be equipped with vertical ribs or with longitudinal ribs for the better gripping of the fabric sheath 2'! and to prevent the fabric sheath from working off of the retaining member 28 when the mop is shaken or otherwise used.
The mo socket 28 is connected by a flexing neck and shaking device 29 integrally with the body 25. I
The socket and body provide a non-scratch buffer or protector which prevents injury to furniture when the mop is brought into contact therewith.
In all of the modifications, the flexing neck serves the very important function of keeping the toe of the mop downwardly against the floor and thus insuring the contact of the mop with the floor when the same is projected into corners and other dimcult places.
While in the foregoing specification, I have set forth a specific structure in great detail for the purpose of illustrating an embodiment of the invention, it will be understood that such details of structure may be varied widely by those skilled in the art without departing from the spirit of my invention.
