Abstract

ABSTRACT OF TEE DISCLOSURE

A connector receives the mop handle at one end there-of and the mop body of a string or yacht type mop in the other end. The connector includes a substantially dome-shaped other end and a flexible strap engages one side of the dome-shaped end, passes around the center of mop strands and is pulled tightly through an aperture in the other side of the dome-shaped end and is locked into position thus holding the mop head firmly into the dome-shaped end. Va-rious locking projections are provided within the dome-shaped end and on the strap to prevent relative movement between the mop head and the dome-shaped end.

SUMMARY OF THE INVENTION
The present invention overcomes this principal disadvantage by providing a connector which is readily manufactured from synthetic plastic materials and which is extremely compact in configuration.

One aspect of the invention consists of a mop connector for a string type mop head having a central por-; tion comprising in combination a handle receiving end and a mop head receiving end, and means to secure the associa-10 ted mop head into said mop head receiving end, said means including a flexible strap held by one end thereof to one side of said mop head receiving end and adjustably secured in locking relationship to the other side of said mop head receiving end, said strap passing around the central por-tion of the associated mop head and holding same firmly ; within said mop head receiving end and a slot formed through adjacent the upper side of said mop head receiving end and on the other side thereof, a plurality of ratchet teeth type projections formed on the outer side of said strap, said ratchet teeth type projections operatively engaging the boundary of said slot when said other end of said strap is pulled through said slot thereby locking said strap .
.. against disengagement from said slot, said mop head receiv-; : ing end being substantially hollow dome-shaped, and means projecting downwardly from adjacent the upper inner sur-face of said mop head receiving end engageable within the central portion of said mop head to prevent relative move-.

ment between said mop head and said connector when said mop head is installed therein.

~nother advantage of the invention is to pro-vide a device of the character herewithin described in which a conventional handle is readily attachable to the other end of the connector, either by screw threading same or, alternatively, by rivetting same, depending upon de-sign parameters.

A yet further advantage of the invention is to provide a device of the character herewithin described in which the attachment of the mop head to the connector com-prises a rapid and simple operation.

Still another advantage of the invention is to provide a device of the character herewithin described in which the attaching strap is locked into position upon the connector when the mop head is installed thus preventing inadvertent disengagement of the mop head from the connec- ~ -tor.

DETAILED DESCRIPTION
Proceeding therefore to describe the invention in de-tail, reference character 10 illustrates a convantional string type mop head somatimes known as a ya~h~ type mop head. It consists of a plurality of ~trands 11 of twisted material which are held centrally within a connector collec-tively designated 12 and the portion of the mop head held within the connector is designated by reference character : :
13 and constitutes a central section or portion~

The ~onnector 12 is preferably made of synthetic plas-tic by injection moulding or the like and includes an upper substantially cylindrical portion 14 constitut m g a handle receiving portion, and a lower sub3tantially doma-~haped portion 15 constituting a mop head receiving portion~

The upper portion 14 includes the smooth hored part 16 and a screw threaded lower part 17~ A handle 18 is pro-vided with a slightly reduced diameter screw threaded end 19 which screw threadably engages within the port:io~ 17 thus drawing the part 20 of the handle downwardly into the smooth bored portiGn 16 theraby giving a firm att:achment o the handle to the connector 12~

..

Strengthening ribs 21 extend be-tween the han-dle receiving portion 14 and the mop head receiving por-tion 15 on the outer surface thereof as clearly shown in Figures 1 and 2.

The interior of the dome-shaped mop head re-ceiving portion 15 is provided with an annular shoulder 22 intermediate the open lower side 23 and the upper in-ner side or surface 24. A pair of diametrically opposite shoulders 25 and 26 are formed on the outer surface 27A
of the dome-shaped portion 15 as illustrated in the draw- ~ .
ings and an aperture 27 extends downwardly through the shoulder portion 25 to the interior of the dome-shaped portion and is bounded by a downwardly projecting rein-forcing portion 2~. ~
:' The opposite shoulder 26 is provided with a relatively narrow slot 29 which extends downwardly into the interior of the dome-shaped portion and this is bound-ed by a larger reinforcing portion 30 which is spaced from the inner wall 31 as clearly shown in Figure 4.
:

A plurality of mop head central portion enga-:~ ging pins or projections 32 extend downwardly into the interior o~ the dome-shaped portion from the area sur-. rounding the lower end of the screw threaded portion 17 :~ of the handle receiving '.

~9'7~
portion 14, the purpose of which will be hereinafter des-cribed.

Also to be noted is the provisic,ll of one or more re-latively small vertically situated ribs 33 situated on the surface of the reinforcing part 30 bo~ding khe slot 29.

An attaching strap collectively designated 34 is pro-vided also preferably manufactured from flexible synthetic plastic material. This strap which is an elongated strip, is provided with a head 35 on one end thereof and a plura-lity of projecting pins 36 are provided on one surface 37 of the strap adjacent this headed end~
.

A plurality of ratchet teeth type projections 38 ex-tend from the opposite side of the strap adjac~nt the dis-tal and 40 thereof and these p.ins 36 and ratchet teeth type pro~ections 38 are clearly shown in Figures S throuyh 8.
r The distal end 40 o the strap is passed downwardly through the aperture 27 from the outside o tha connector with the pins 36 facing inwardly and the teeth 38 facing . -; ou~wardly.

~he central portion 13 of the associated mop head 10 ~q37~
is then placed across the open end 23 of the mop head re-ceiving portion 15 o the connector whereupon the strap i8 passed around this central section and the di~tal end 40 is ed upwardly through the relatively narrow ~lot 29 as S shown in Figura 90 It should be noted that the dimensions of slot 29 are just su~ficient to take the distal end 40 of the strap 34 and further movement of the strap through slot 29 i~
restricted by the first ratchat tooth type projection specifically designated 38Ao An aperture 41 is provided adjacent the distal end 40 thus enabling a hooked tool (not illustrated3 to be en-, gaged therein or, alternatively~ to enable this distal end of the strap to be attached to a fixed anchoring point (not illustrated30 Either method allows the strap to be forced through the slot 2g, the resiliency of the teeth 3.8 allowing ~hem to pass through the ~lot 29 and to snap outwardly onca they are clear~ . . -~0 ' ~ha strap is pulled tightly thus compress~lg the c0n-~ , ' tral portion 13 of the mop head and forcing same into engagement with the downwardly facing projection 320 The pins 36 also frictionally engage within the central sections so that when -the strap is pulled as tightly as possible, the mop head is firmly clamped in position wi-th-in the mop head receiving portion 15, it being observed that it is forced upwardly through the open end 23 to the position shown in Figure 9.

At this point, one of the ratchet teeth speci-fically designated 38A engages the outer surface 42 of the shoulder 26 and prevents the strap from releasing. In other words, the strap is held in fixed locking relation-ship around the central section 13 of the mop head thus holding same firmly to the connector and preventing any inadvertent disengagement with the projections 32 and pins 36 preventing any relative movement o~ the mop head with the connector.

Finally, if desired, the end projecting above the shoulder 26 may be cut off and a staple or the like 43 engaged through the side of the connector, through the strap and into the reinforcing portion 30.

Since various modifications can be made in my inven-g 7~'a~;,9L
tion as hereinabove described, and ~any apparently widely diff0rent embodiments of same made within the spirit and scope of the claims without departing from such spirit and ~cope, it is intended that all matter contained in the accompanying specification shall b0 interpreted as illustrative only and not in a limiting sense.
