Mop
The mop includes a handle, a pusher, a front cam, a rear cam, a mop element support and a mop element. The pusher may include a front arm and a rear arm with cam-engaging surfaces. The mop element support has a center portion;, a front portion and a rear portion. The front portion is attached to the center portion by a front living hinge and the rear portion is attached to the center portion by a rear living hinge. As the user moves the pusher relative to the shaft, the pusher would act upon the front cam and the rear cam. The front cam and the rear cams would begin to rotate and cause the rear portion of the mop element support to fold along the rear living hinge and the front portion of the mop element support to fold along the front living hinge. After the mop element has been squeezed, the user would then move the pusher in the opposite direction along the shaft. The pusher would engage the front and rear cams causing the front and rear portions of the mop element support to unfold along the living hinges.

This invention pertains to mops and more specifically to a hinge mop.
BACKGROUND OF THE INVENTIONMops are used to clean floors and pick up spills. One type of mop is a sponge mop. Sponge mops typically have some type of mechanism to squeeze the liquid from the mop element. One type of sponge mop is a roller mop which utilizes a series of rollers to squeeze the liquid from the mop element. An example of a roller mop is shown in U.S. Pat. No. 5,097,561. Another type of sponge mop is a butterfly mop in which the mop folds along a central axis.
Another type of sponge mop is a hinge mop which utilizes a hinged portion of the mop element support to squeeze the fluid from the mop element. The difficulty in using such a hinge mop is that the user must bend down to squeeze the mop in order to assure that the liquid will be expelled adequately. In addition, the wringing operation can cause the user's hands to become wet and/or soiled.
There is a need for a flat mop which does not require the user to bend over to squeeze the liquid from the mop and get his hands wet. There is also a need for a flat mop which is easier and less expensive to manufacture and performs better than prior mops.
These and other advantages of the invention, as well as additional inventive features, will be apparent from the description of the invention provided herein.
BRIEF SUMMARY OF THE INVENTIONThe invention provides a mop which includes a handle, a pusher, a front cam, a rear cam, a mop element support and a mop element. The pusher may include a front arm and a rear arm with cam-engaging surfaces. The mop element support has a center portion, a front portion and a rear portion. The front portion is attached to the center portion by a front living hinge and the rear portion is attached to the center portion by a rear living hinge. The front portion folds along the front living hinge and the rear portion folds along the rear living hinge when the mop is in the closed position.
When the user wishes to expel liquid from the mop, the user would grasp the handle with one hand and the pusher with the other hand. The user would then move the pusher along the longitudinal axis of the shaft. As the user moves the pusher relative to the shaft, the pusher would act upon the front cam and the rear cam. The front cam and the rear cams would begin to rotate and cause the rear portion of the mop element support to fold along the rear living hinge and the front portion of the mop element support to fold along the front living hinge. As the mop element support was being moved forward, liquid would then be squeezed from the mop element as the front and rear mop element supports came closer together.
After the mop element has been squeezed, the user would then move the pusher in the opposite direction along the shaft. The pusher would engage the front and rear cams causing the front and rear portions of the mop element support to unfold along the living hinges.
BRIEF DESCRIPTION OF THE DRAWINGS
Referring to
The handle 102 may include a tubular shaft 120 with a plastic cap 122 at one end of the shaft and a threaded end cap 124 at the other end of the shaft. In this embodiment, the shaft 120 is made of tubular metal and the caps 122, 124 are made of plastic. In other embodiments, the shaft and caps may be unitary and may be made of other materials, such as plastic or wood.
Referring to
The handle 102 is inserted inside the pusher 104. The handle 102 is then attached to the boss 106. In this embodiment, the threads 134 on the end cap 124 engage the threads 136 in the boss 106 as shown in
Referring to
The boss 106 may include an attachment portion to attach the boss 106 to the mop element support 112. Referring to
Referring to
Referring to
The front cam 108 and the rear cam 110 may be attached to the mop element support 112 as shown in
Referring to
The mop element support 112 may include an attachment portion for the boss 108. In this embodiment as shown in
Referring to
Referring to
The mop element support 112 may also include an attachment portion for a scrubbing device, such as a scrub brush. In this embodiment, as shown in
Referring to
When the user wishes to expel liquid from the mop 100, the user would grasp the shaft 120 with one hand and grasp the pusher grip 126 with the other hand. The mop would be in the open position shown in
As the pusher 104 is moved further towards the mop element support, the cams 108, 110 further rotate causing the mop element support to fold along the living hinges 246, 248. As the mop element support is being folded, liquid is squeezed from the mop element 114 as the front and rear portions 242, 244 of the mop element support come closer together as shown in
After the mop element has been squeezed, the user would then move the pusher 104 in the opposite direction along the shaft 120. The cam-engaging surfaces 144, 146 on the pusher engage the pusher engaging surfaces on the front and rear cams 108, 110. The cams rotate causing the front and rear portions of the mop element support 114 to unfold along the living hinges 246, 248. As the pusher 104 is moved further along the shaft 120 towards the opposite end of the handle, the movement of the pusher yoke is stopped when the engaging surface 144 on the front arm of the pusher engages the stop portion 194 on the front cam as shown in
