Description

TECHNICAL FIELD OF INVENTION

The present invention relates to a handle apparatus that can be used on cleaning implements and the like. One embodiment of the invention comprises a multi-function one piece top grip and trigger apparatus for a liquid dispensing or spray mop.

BACKGROUND OF INVENTION

The trigger and handle interface on many current liquid dispensing or spray mops are uncomfortable to use, and designed to be merely the triggers for the spray mop. These triggers are typically designed to be operated in only one hand position, and to be activated with only two fingers at any one time, which causes stress on the user's hand muscles. A frequent problem with liquid dispensing/spray mops, which are not used with a bucket, is that when a user attempts to lean the mop handle against a wall in a resting position, the handle will often slide against the wall and fall onto the floor, frequently resulting in damage to the trigger.

Also, the top grip area is the control area when mopping, where the hand applies pressure to twist the mop in a figure eight motion. Current spray mops having a straight handle without grips can cause the user to grip the mop tightly when mopping and hold the wrist at an odd angle, leading to fatigue and injury. When using the mop as a dust mop (straight line pushing), the grip is the single point where the user holds and controls the mop. When used vertically to clean walls, the user supports the mop with two hands with one being on the top grip. This is also an important area when transporting the mop by carrying. Current spray mops do not include a top grip that addresses all six of these uses.

SUMMARY OF INVENTION

An object of the present invention is to provide a multi-functional handle apparatus for use on a cleaning instrument, such as a mop. Another object of the invention is to provide a handle apparatus that reduces the likelihood of sliding against a wall and falling to the floor. Yet another object of the invention is to provide a handle apparatus that includes a trigger and means for protecting the trigger in the event the apparatus falls to the floor.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF INVENTION

A handle apparatus according to a preferred embodiment of the invention is illustrated in FIGS. 1-3, and shown generally at reference numeral 10. As shown in FIGS. 1 and 2, the apparatus 10 comprises an elongate cylindrical shaft section 12, a bulbous section 14 formed at the top of the elongate cylindrical section 12, a flange section 16 formed proximate the bottom of the cylindrical section 12. A trigger 18 is positioned within a recess formed in the elongate cylindrical section 12, as shown in FIGS. 1 and 2. The handle 10 can generally be made of plastic or other suitable material. The handle 10 can be made by injection molding or other suitable process.

The handle apparatus 10 can be utilized on a cleaning implement, such as a liquid dispensing mop. A liquid dispensing mop according to a preferred embodiment of the invention is illustrated in FIGS. 4 and 5, and shown generally at reference numeral 100. The handle apparatus 10 is mounted at the top of an elongate shaft 102 of the mop 100, as shown in FIGS. 4 and 5. The handle 10 can include an aperture 22 for receiving a fastening member, such as a screw or pin, to attach the handle 10 to the shaft 102 of the mop 100. The trigger 18 of the handle 10 can be operatively connected to a liquid dispensing unit 104 containing a supply of cleaning liquid. The trigger can be operatively connected such that pressing down on the trigger 18 causes the liquid dispensing unit 104 to dispense a predetermined amount of cleaning liquid through a tube 108 proximate a cleaning head 106 that is attached at the bottom of the mop shaft 102.

The bulbous top section 14 has an oblate (flattened) spheroid shape, as shown in FIGS. 1 and 2. That is, the shape of a flattened ball. The bulbous top section 14 can include a gripping band 24, shown in FIGS. 1-3, extending around the circumference of the bulbous top section 14. The gripping band 24 is comprised of a material having a high coefficient of friction such that when placed against wall surface the gripping band 24 frictionally engages the surface, thereby reducing the tendency of the handle 10 to slide when leaned against a wall “W”, as shown in FIG. 6. The gripping band 24 can be comprised of black thermoplastic elastomer (TPE) rubber that is in-molded to the top section 14. A plurality of indentations 34 can be formed in the gripping band 24, as shown in FIGS. 1-3. The indentations 34 help further facilitate frictional engagement reducing the risk of sliding against a wall surface. The gripping band 24 can hold the mop 100 in place when the mop is placed against the wall at a side angle of up to thirty degrees. In addition, the indentations 34 provide a more comfortable grip for the user. The indentations 34 helps the user's hand grip the handle 10 when mopping thus reducing the force necessary to hold the mop 100 and give it a twisting motion.

The oblate spheroid shape of the top section 14 properly fits the human hand when gripped from above, as shown in FIG. 7, for damp mopping. This flattened ball shape of the top section 14 provides a more ergonomic fit for the user's hand than a completely round ball shape. The top section 14 is multi-functional as it provides a more comfortable grip for the user and reduces the risk of the mop 100 slipping when leaned against the wall “W”, as shown in FIG. 6.

The trigger can be operated with a full hand handgrip of four fingers on the trigger 18, as shown in FIG. 8, a partial grip of less than four fingers, or from above with the user's palm on the top section 14 and a single finger on the trigger 18, as shown in FIG. 9.

The flange 16 extends around the circumference of the cylindrical section 12 proximate the base of the cylindrical section 12, as shown in FIGS. 1 and 2. The outer edge of the flange reaches slightly beyond the depth of the trigger 18, as illustrated by the “Y” axis in FIG. 2. As such, if the mop 100 is dropped or falls to the floor, the flange 16 hits the floor preventing the trigger 18 from directly impacting the floor, thus protecting the trigger 18 from damage.

In addition, the flange 16 can reduce stress on the user when dust mopping by pushing the mop 100 and handle 10 like a vacuum, and also when using the mop 100 in a vertical position to clean walls. The user can rest his hand “H” against the flange 16, as shown in FIG. 10. This allows the user to rest the mop 100 on their hand “H” without a tight grip during straight line dust mopping or overhead mopping. Also, during overhead use, the flange 16 prevents water from flowing down the handle 10 and onto the user.

The handle apparatus 10 provides a variety of functional benefits. The trigger 18 is adapted for operation in multiple hand positions to reduce user stress when dispensing the cleaning solution. The handle 10 helps prevents the mop 100 from sliding on a wall and falling to the floor. The shape, finish and design of the bulbous top section 14 reduces stress on the user when damp mopping. The flange 16 protects the trigger 18 from breakage if the mop 100 falls to the floor, and reduces stress on the user when straight-line dust mopping, cleaning walls and working overhead.
