Abstract:
An adjoined flexible two-piece swivel joint type floor cleaning attachment in which either upper or lower and/or both sections are made from a unitary flexible elastomer material allowing for a unitary quick release clamp mechanism that adjoins to a cleaning head apparatuses. The combination of the quick release unitary flexible clamp mechanism adjoined to a jam/stop swivel mechanism allows for small cleaning devices, such as scrub brushes, wall washers, abrasive pad holders, etc. to be easily engaged and disengaged allowing the cleaning device to also be used as a hand held device. Furthermore, swivel type floor cleaning devices will no longer need their own swivel type connector affixed onto the cleaning head thus making the cleaning products more cost efficient.

BACKGROUND OF THE INVENTION 
     1. Background of the Invention 
     The present invention relates to a scrubbing, dust mopping, or a sweeping apparatus and in particular to scrub brushes or applications where material is being removed by an apparatus. The present invention relates to a swivel joint two piece unitary flexible molded elastomer attachment that allows multiple cleaning apparatuses to be attached and detached for cleaning purposes. The new innovation allows for easy engagement and disengagement of the swivel mechanism to the cleaning head apparatus thus eliminating costly swivel joints that are adjoined to prior art swivel joint type cleaning apparatuses. In addition, the swivel type cleaning head apparatuses can be used as a hand held cleaning apparatus when not engaged with the swivel type joint quick release mechanism. In addition, using an elastomer material for the jaw type connector that encompasses the swivel axis allows for the jaws to be preloaded thus the swivel does not become loose. 
     2. Description of Prior Art 
     The standard swivel type floor cleaning apparatus has two primary components. The first component is the floor cleaning head such as a dust mops, wall washer, grout cleaner, scrub brush, abrasive pad holder. All these floor-cleaning apparatuses have an adjoined embodied swivel type connector that is permanently attached to the cleaning apparatus making them very costly. The second primary component of floor cleaning apparatuses is the handle which is usually a cylindrical pole that is inserted into the swivel joint handle connector. The floor handle connector is only removable by unthreading the lock nut or twisting the handle out of the handle connector leaving the swivel joint mechanism attached to the cleaning apparatus. The combination of the unitary elastomer quick disconnect and rotating swivel type mechanism permits all floor cleaning apparatuses to be pushed and pulled by exertion of a force on the handle and flex when coming in contact with obstacles. Prior art has also addressed the issue of loose swivels as in U.S. Pat. No. 4,763,377 
     One significant problem with swivel type floor cleaning apparatuses is the swivel type apparatus eventually breaks around the swivel type axis and/or upper and lower support members supporting the axis when either hitting stationary objects or abuse. Also, when jam pin is inserted into the swivel joint to allow only one position to be retained, the leverage caused by the jam/stop causes swivel type attachments that are not made from flexible material to easily break. Also swivel joints that are used to adjoin a cleaning apparatuses like scrub brushes, wall cleaning, abrasive pad holders, flat wet mops and small dust mops are attached to the cleaning apparatus making the cleaning apparatus costly to manufacture. Such is the case in prior art U.S. Pat. No. 4,763,377. Also, the cleaning apparatus can only be used for floor cleaning due to the large swivel joint adjoined to the cleaning apparatus. Prior art such as “Flexible Elastomer Floor Dust Mop Attachment”, U.S. Pat. No. 6,237,182 does allow for easy disengagement and does preload the axis due to the elastomer material wrapping around the axis, but due to its flexible joint between the clamp and the handle connector, verses a swivel type joint, the flexible member does not allow for small cleaning device such as scrub brushes and other small cleaning apparatuses to lay flat on the ground during the cleaning operation and instead part of the scrub brush is lifted up when the flexible joint is pivoted. Simply put, the flexible joint acts as a spring action causing the floor cleaning apparatus to lift up on the opposing side of the pivoting action. On large dust mops this is not so evident, but on smaller cleaning apparatuses such as a scrub brush, wall washers and small dust mop frames this is unfortunately extremely apparent. Also, the flexible one piece joint cannot allow for the swivel movement to become fixed and not flex when cleaning areas that do not require the cleaning apparatus to swivel but instead to remain stationary. However, the present invention allows for the swivel movement to be jam/stop by the use of a jam pin thus stopping the swivel movement. Other disengagement type swivel joints like Large dust mop frames do have disconnecting swivel joints like U.S. Pat. No. 5,901,402 but due to the large size of the connector, multiple parts causing looseness when attached to a small cleaning device they are not functional. Also, prior art U.S. Pat. No. 4,763,377 prevents loose swivels but is not as cost effective as the present invention due to the swivel joint being attached directly to the cleaning apparatus so when the brush is worn both the brush and swivel joint is discarded thus making the product more costly that a reusable swivel joint that can be used on other cleaning apparatuses. 
     Therefore, a significant need exists to improve upon the previous patents that allows for an elastomeric flexible swivel connector that when abused or placed in a fixed position flexes thus eliminating breakage and negotiates around obstacles that would of otherwise break or damaged the fixed position or swivel type handle connector. Also, allows for a more cost effective non-loosening swivel type floor connector that can be easily detached from multiple cleaning devices thus allowing the cleaning apparatus to also be used for hand operations thus reducing cost, space and increasing durability. 
     SUMMARY OF THE PRESENT INVENTION 
     The present invention is a swivel type mechanism that is affixed at the location between a handle and head of the floor cleaning apparatus to provide a flexible member at the junction where the floor cleaning handle apparatus is attached to the floor cleaning apparatus head. Through use of the swivel type connector member, when the floor cleaning apparatus head comes in contact with a stationary object the floor cleaning apparatus will flex beyond 90 degrees deflection around the longitudinal axis in relation to the floor cleaning apparatus. 
     It is therefore an object of the present invention to provide an elastomer disengaging apparatus by which a flexible floor cleaning apparatus can swivel without being damaged when abused or loosening and also be used for hand held operations that can be economically manufactured. 
     Further novel features and other objects of the present invention will become apparent from the following detailed description, discussion and the appended claim, taken in conjunction with the drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Although specific embodiments of the invention will now be described with reference to the drawings, it should be understood that such embodiments are by way of example only and merely illustrative of but a small number of the many possible specific embodiments which can represent applications of the principles of the invention. Various changes and modifications obvious to one skilled in the art to which the invention pertains are deemed to be within the spirit, scope and contemplation of the invention as further defined in the appended claims. 
     In the preferred embodiment, the insert member  10  in  FIG. 1  is made of any flexible substance with memory such as rubber, urethane, nylon, plastic, titanium, polyvinyl. It is also within the spirit and scope of the present invention for the attachment to be made of flexible but strong plastic such as mylar, polypropylene or any other flexible material exhibiting the required characteristics. 
     Referring to  FIG. 1 , there is shown at  10  the present invention swivel connector or multiple cleaning apparatuses. The apparatus is made from an elastomeric material comprised of two pieces upper support member  19  and lower support member  18  joined together at the rotating axis  180 . Lower support member  18  is made from an elastomeric flexible material with sufficient memory to retain support bar  16 . Either and/or both  18  or  19  is made from a flexible elastomeric material thus allowing the clamp mechanism  16  and support frame  161  to rotate laterally around the flexible mid section axis  20  when the support pin  185  is engaged or when not engaged to flex beyond full 180 degrees deflection thus eliminating breakage that could occur to handle, connector or floor cleaning devices. Phantom lines illustrating the flexing movement can be seen when pin  185  is engaged. 
     It should be noted that the rotating axis is not limited to the type of axis used. For example the rotating axis member  180  could be an integrally unitary molded shaft that makes up the lower support member  18  or could be a bolt, pin, rivet, fastener etc. In the preferred molded embodiment, the apparatus  10  comprises a longitudinal section  14  and a lateral section  16  that are interconnected by axis  180  as shown in cross sectional view  FIG. 10 . In general appearance, the two-piece molded inserts looks like an extended Roman numeral one with the top portion, item  130  being the receptacle to hold the handle  120 . The handle is supported by the attachment body  14  that is a recessed cavity to hold the floor handle. Accordingly the upper sleeve portion of the cylindrical sleeve section  130  includes an axial bore  140  having a uniform dimension so as to receive therein the transverse dimension of the handle  120 . The thickness of the material-encapsulating handle  120  is sufficient to not crack when impact to the head of the floor cleaning apparatus occurs. The upper sleeve section  130  has a diameter to tightly receive in a generally slip-fit relationship the transverse dimension of the handle to frictionally retain the handle therein. It is not limited to the intent of this invention as to how the handle is retained and can be either threaded or attached by a bolt or rivet. The overall configuration of the lower member  18  as it joins to the floor cleaning apparatus frame support clamp recess cavity  160  resembles an inverted “T” with the mid portion of the vertical leg being thin in the middle and the lower portion of the leg extending outboard in both the left and right lateral directions to form the clamp mechanism  16  as shown in  FIG. 1  The clamp mechanism  16  when attached to the floor cleaning head support frame  170  retains the floor cleaning apparatus head. When the clamp mechanism 
     Referring to  FIG. 2 . there is illustrated in a perspective view the relationship between the perspective floor cleaning brush head  163  and floor cleaning handle attachment  10 . The present invention includes a two sectional connector adjoined together through axis shaft  180 . The lower section  12  comprising of a clamping mechanism section and an upper section  11  comprising of the handle support hole. Both sections are a one piece unitary molded part adjoined only be way of axis  180 . The floor cleaning brush head support frame  161  is encapsulated by the clamp mechanism  16  and supported by the lateral recess cavity  160 . The support frame  161  has an approximate diameter between 0.25 to 0.50 of an inch. The larger diameter allows for the cleaning head to be a unitary one piece injected molded apparatus. The lower support member  18  adjoins the clamp mechanism  16 . When the clamp mechanism  16  is disengaged from the support frame  170  the cleaning brush head  163  or cleaning head devices can be used as a hand held cleaning device using ergonomic hand hold  17 . 
     Referring to  FIG. 3 . Illustrates the clamp mechanism  16  and the protruding push lever  171  that allows leverage to open the jaws of the clamp. 
     Referring to  FIG. 4 . Illustrates the movement of the swivel connector when in contact with a stationary object. The floor cleaning attachments lower support member  18  can rotate around the axis shaft  180  over 90 degrees in relation to the floor cleaning handle support  14 . 
     Referring to  FIG. 5 . there is Illustrates the unitary elastomeric clamp mechanism. The clamp mechanism  16  has an upper jaw  152  and lower jaw  150  with an opening slotted jaw  170  that extends laterally. Opening  170  allows for access to cavity  160  that loosely supports the floor dust mop frame in order to pivot along the lateral axis. The upper clamp  152  remains rigid while the lower clamp  150  pivots around the lateral axis at  172 . Protruded lever  171  when depressed displaces cavity  172  allowing for lower clamp  150  to move forward in relation to upper clamp  152  allowing for opening  170  to enlarge as shown in  FIG. 6 . Hinge  173  allows for a preload to occur around the clamping mechanism. The peripheral side arm type jaws  177 , wrap around the axis shaft  180 . 
     Referring to  FIG. 6 . There is Illustrates the elastomeric connector with phantom lines illustrating the flexing movement when pushed and pulled by exertion of a force thus preventing said handle member, swivel attachment, and/or floor cleaning apparatuses from being damaged. There is Illustrated the movement of the clamp mechanism between upper and lower clamps  150  and  152  when force is applied to protruded lever  171  on side  174 . 
     Referring to  FIG. 7 . there is an isometric illustration of the attachment in its entirety. 
     Referring to  FIG. 8 . there is Illustrated a cross sectional view with the flexible elastomeric material shaped as a rectangle. The purpose of a rectangular shape is to allow for maximum flexibility in the lateral movement yet retains rigidity in the forward and aft movement. 
     Referring to  FIG. 9 . there is shown an isometric illustration of an alternate embodiment of present invention without the protruding lever to ease in opening the clamp in its entirety. Also shown is jam pin  185  inserted into support member  18  and arm type jaws  177  to jam/stop the rotation of the swivel joint around axis  180 . Storage hole  187  is shown that would house the jam pin  185  when normal swivel movement of the connector is required. 
     This alternative embodiment is identical for attaching the base of the apparatus to a floor cleaning device support frame that is illustrated in  FIG. 9 . The alternate attachment is identical to the previous attachment described except has no protruding lever  171 . However, there is still the open recessed cavity  170  as depicted in  FIG. 5  that allows for ease of installing the attachment onto the floor cleaning apparatus frame. To install the alternate embodiment, the operator must apply force to press on the attachment onto the floor dust mop frame. 
     Referring to  FIG. 10 . there is Illustrated a cross sectional view of the attachment in its entirety, The peripheral symmetrical side arm type jaws  177 , preloaded and wrapped around the unitary elastomer expandable axis shaft  180 . 
     Referring to  FIG. 11 . there is illustrated a section view of the peripheral symmetrical arm type jaws  177  revealing the preload movement once inserted onto the expandable elastomer axis shaft  180 . The preloaded jaws  177  around expandable elastomer shaft  180  eliminates wobble and excessive movement of the cleaning head during a cleaning operation. 
     Referring to  FIG. 12 . there is illustrated an alternate embodiment  178  that encapsulates axis shaft  180 . The hole size for shaft  180  will be undersized causing a preload condition to eliminate wobble during a cleaning operation. This method would allow for a pin, fastener or bolt to attach the upper and lower members together. 
     Defined broadly, the present invention is a two-piece swivel type floor cleaning attachment that can easily be engaged or disengaged to small cleaning apparatuses, such as scrub brushes, allowing for hand operation of prior art floor-cleaning apparatuses. 
     Therefore, through use of the present invention, a flexible swivel type attachment can be easily engaged or disengaged and not be affixed onto floor cleaning apparatuses can now be manufactured that is economical, and can be also used as a hand held cleaning device since a u-joint or other type swivel attachments are no longer needed to be affixed to the cleaning head device.
