DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 1A to 8C, a mop in accordance with the invention comprises the following components as discussed in detail below.
An outer tube 10 has an upper, knurled holding portion 11 and two opposite lower through holes 101. An inner tube 20 is telescopically coupled to the outer tube 10 (i.e., partially slide into or out of the outer tube 10). A joint 21 is provided at a lower end of the inner tube 20. The joint 21 comprises two opposite, spaced about 90-degree bent members 211 with a slot 212 defined therebetween, each bent member 211 having a cam member 2112 on an underside of an outer end and a through hole 2111 in a vertical portion proximate the bending point, and a spring depressible detent including a helical spring 2131 disposed in a receptacle 214 in a lower portion of the inner tube 20, and a steel ball 2132 engaged with a lower end of the spring 2131.
A limit sleeve 30 is fastened in an upper end of the inner tube 20 and comprises a lower toothed section 31 having teeth facing upward, and a fastening ring 32 having an axial hole 321 fastened in an upper end. A hollow, cylindrical guide member comprises a spiral groove 41 longitudinally extending through a central line, and a plurality of pawls 42 formed along a bottom end. The guide member 40 is slidably disposed in the limit sleeve 30. That is, an upward movement of the guide member 40 will be stopped when it contacts the fastening ring 32 and a downward movement of the guide member 40 will cause the pawls 42 to mesh with the toothed section 31.
A spiral member 50 comprises a top enlargement 51 fastened in the holding portion 11 of the outer tube 10. The spiral member 50 passes through the groove 41 and is adapted to rotate to cause the guide member 40 to rotate too. The pawls mesh with the toothed section 31 (i.e., locked) when the outer tube 10 moves downward. Thus, the inner tube 20 rotates too. The pawls 42 disengage from the toothed section 31 (i.e., unlocked) when the outer tube 10 moves upward. Thus, only the guide member 40 rotates. Moreover, a plurality of (two) sleeve-like buffer members 52 are provided with the spiral member 50 passing through. The buffer members 52 act as pads to smooth upward and downward movements of the spiral member 50.
A lock assembly 60 comprises an inner sleeve 61 including two opposite upper through holes 613 and a flared lower portion 611 having a plurality of longitudinal gaps 612 spaced therearound; an outer sleeve 62 put on the inner sleeve 61 and including two opposite upper openings 621 and a flared lower portion 622; and a U member including a cam 632 on bottom of either end, and two pivot pins 631 each driven through one end of the U member 63, the opening 621, the through hole 613, and the through hole 101 to pivotably secure the U member 63, the outer and inner sleeves 62, 61, and the outer tube 10 together.
As shown in FIG. 6, the U member 63 is pivoted upward to urge the cams 632 against the bottom edges of the openings 621. As such, the outer sleeve 62 moves downward to clamp the lower portion 611 which in turn clamps the inner tube 20. As a result, the outer tube 10 and the inner tube 20 are locked (i.e., the lock assembly 60 is locked).
As shown in FIG. 7, the U member 63 is pivoted downward to urge the cams 632 against the top edges of the openings 621. As such, the outer sleeve 62 moves upward to loosen the lower portion 611 which in turn loosens the inner tube 20. As a result, the outer tube 10 and the inner tube 20 are unlocked (i.e., the lock assembly 60 is unlocked).
Preferably, the number of the gaps 612 is four.
A stop sleeve 70 is fixedly provided on an intermediate portion of the inner tube 20. The outer tube 10 is allowed to slide downward until it contacts the stop sleeve 70.
A strand mount 80 comprises a plurality of strands 81, a projection 82 on a top center, the projection 82 disposed in the slot 212 and including a transverse through hole 821, an arcuate top recess 822 with the steel ball 2132 rested thereon, and a pivot pin 823 driven through the through holes 2111 and 821 to pivotably secure the inner tube 20 and the strand mount 80 together.
In an upright position of the inner tube 20, the cam members 2112 are urged against the top of the strand mount 80 and the steel ball 2132 is pushed downward to urge against the recess 822 by the spring 2131. As a result, the inner tube 20 is locked (see solid lines of the inner tube 20 of FIG. 5). Also, the strand mount 80 is locked (i.e., not rotatable).
In an oblique position of the inner tube 20, the cam members 2112 are not urged against the top of the strand mount 80 and the steel ball 2132 is not urged against the recess 822 by the spring 2131. As a result, the inner tube 20 is unlocked (see dash lines of the inner tube 20 of FIG. 5). This is a use position of the mop with the strand mount 80 being rotatable.
A pail 90 comprises a mop receptacle 91 disposed therein. The strand mount 80 can be disposed in the mop receptacle 91.
An individual may use the mop to clean floors after locking the lock assembly and unlocking the inner tube 20 and the strand mount 80 (i.e., the inner tube 20 being inclined). After use, for wringing the wet strands 81 the individual may put the strand mount 80 in the mop receptacle 91. Next, pivot the U member 63 downward to allow the inner tube 20 to slide in the outer tube 10. Next, put the inner tube 20 in an upright position by locking both the inner tube 20 and the strand mount 80. Next, press and downward move the outer tube 10. Thus, the guide member 40 rotates due to the downward spiral movement of the spiral member 50 therethrough. The rotation of the guide member 40 causes the inner tube 20 to rotate too because the lock assembly 6 is unlocked. And in turn, the strand mount 80 rotates. A centrifugal force is thus created to squeeze water out of the strands 81. Above steps can be repeated until the strands 81 are sufficiently wrung.
While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
Typically, an individual has to use both hands to wring the wet mop after use.
It is a laborious job.
Recently, there are many types of so-called automatic mop wringers commercially available. For example, one type of the mop wringer comprises a foot step which in response to be pressed will rotate a mop receptacle in a pail via a gear-based actuation mechanism so that a wet mop in the mop receptacle can be wrung.
However, the person with one foot repeatedly pressing the foot step with great force and the other foot standing on the floor may slip or fall if sufficient care is not taken. Thus, the need for improvement still exists.
