ANTI-TURN-BACK TWIST MOP
The present invention provides an anti-turn-back twist mop including a main handle, a holding sleeve, a mop cloth and a clutch member. The holding sleeve is up and down movably and rotatably fitting over the main handle. Two ends of the mop cloth are respectively connected with the main handle and the holding sleeve. When rotating the main handle and holding sleeve relative to each other, the mop cloth can be wrung dry. The clutch member is fitting over the main handle and movable therealong. When rotating the main handle, the clutch member is rotated along therewith. A bottom end of the clutch member and a top end of the holding sleeve are respectively formed with ratchets engaged with each other. By means of the engagement between the clutch member and holding sleeve, when wringing the mop cloth, the main handle is prevented from being rotated back by the pulling force of the mop cloth.
The present invention relates generally to a cleaning device, and more particularly to an anti-turn-back twist mop in which the main handle is prevented from turning back in wringing process.
BACKGROUND OF THE INVENTIONWithin certain limits of wrist twists, the user must release the main handle 12 and adjust his/her wrist back to re-hold the main handle 12 for next twist after the main handle 12 is rotated to a certain angle.
During the wringing process, the mop cloth 16 will exert a reaction force onto the main handle 12. As soon as the main handle 12 is released, the reaction force of the mop cloth 16 will bring the main handle 12 turning back. This makes it more laborious and time-consuming to wring the mop cloth 16 dry. To overcome this problem, another conventional twist mop is equipped with an anti-turn-back mechanism for avoiding turn-back of the main handle. By means of the anti-turn-back mechanism, the main handle can be positioned after rotation to prevent turning back by the mop cloth. However, such anti-turn-back mechanism is quite complicated and hard to manufacture, and inconvenient to use.
SUMMARY OF THE INVENTIONIt is therefore a primary object of the present invention to provide an anti-turn-back twist mop in which the main handle is prevented from turning back in wringing process.
It is a further object of the present invention to provide the above anti-turn-back twist mop in which the anti-turn-back mechanism is simplified to manufacture and use.
To achieve the above and other objects, the anti-turn-back twist mop according to the present invention includes a main handle, a holding sleeve, a mop cloth and a clutch member. The holding sleeve is up and down movably and rotatably fitted on the main handle. When rotating the main handle and holding sleeve relative to each other, the mop cloth can be wrung dry. The clutch member is fitting over the main handle and movable therealong. When rotating the main handle, the clutch member is rotated along therewith. Bottom end of the clutch member and top end of the holding sleeve are respectively formed with ratchets engaged with each other. The twist mop further includes a restriction member disposed between the clutch member and the holding sleeve. The restriction member only permits the clutch member to move relative to the holding sleeve without substantially detaching therefrom. Two ends of the mop cloth are respectively connected with the bottom end of the holding sleeve and the bottom end of the main handle. By means of rotating the main handle and the holding sleeve relative to each other, the mop cloth can be wrung dry. By means of the engagement between the clutch member and holding sleeve, when wringing the mop cloth, the main handle is prevented from being rotated back by the pulling force of the mop cloth.
The present invention can be best understood through the following description and accompanying drawings wherein:
Please refer to
The main handle 30 has an outer circumference formed with a polygonal fitting section 32 along a part of the length of the main handle 30 as shown in
Please refer to
The mop cloth 50 includes several side-by-side arranged cloth strips 52. A top end of the mop cloth 50 is fixed with the circular tray 45 of the holding sleeve 40, while a bottom end of the mop cloth 50 is intruded into a bottom section of the ring cap 35 as shown in
The clutch member 60 is a hollow cylindrical body. An engaging section 62 is disposed on an inner circumference of the clutch member 60 as shown in
The restriction member 70 is disposed at a juncture between the clutch member and the holding sleeve. The restriction member 70 only permits the clutch member to move relative to the holding sleeve by a small distance without substantially detaching from the holding sleeve. In this embodiment, the restriction member is a cylindrical restriction collar 70 having a shoulder section 72 on an inner circumference of the restriction collar 70. The restriction collar 70 is fitted around the outer circumference of the clutch member 60 and screwed on a thread 44 formed on an outer circumference of a top end of the holding sleeve 40. The shoulder section 72 of the restriction collar 70 is spaced from the annular rib 64 of the clutch member 60 by a gap. When the clutch member 60 is moved upward, the annular rib 64 is stopped by the shoulder section 72 of the restriction collar 70 as shown in
In use, the holding sleeve 40 is moved toward the bottom end of the main handle 30 to suspend the mop cloth 50 as shown in

Please now refer to
The position where the ratchets 42, 65 are arranged is not limited to the position as shown in
After the main handle 110 and the holding sleeve 120 are relatively turned to wring dry the mop cloth 130, a user can unscrew the restriction collar 150 to move the same upward as shown in
Referring to
In use of the present invention, during the wringing process of the mop cloth, the main handle is prevented from being rotated back due to the pulling force of the mop cloth. Therefore, the present invention can be more conveniently used. Also, the present invention has simple structure and thus is easy to manufacture.
The above embodiments are only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiments can be made without departing from the spirit of the present invention.
