MOP
A mop includes a handle; a base seat fixedly disposed at a bottom end of the handle; two links, top ends of the links being pivotally connected with two lateral sides of the base seat; and a compression seat including a pivot block and two compression boards pivotally connected therewith. Bottom ends of the links are pivotally connected with the compression boards. A foam rubber is disposed under bottom face of the compression seat. When shifting a shift lever, via a drive rod, the compression seat is moved into the base seat or moved out of the base seat and stretched to straighten the foam rubber. In the stretched state, the two links are tilted and a distance between bottom pivot points of the links is larger than a distance between top pivot points thereof. Outer lateral faces of the links abut against two lateral sides of the base seat as supports.
1. Field of the Invention
The present invention relates generally to a cleaning device, and more particularly to a mop.
2. Description of the Related Art
In the state of
Referring to
In practical use of the conventional mop, it is found that the compression seat is likely to bend and move into the base seat 3. This will affect the mopping effect. Referring to
The conventional mop has another shortcoming existing in the compression process of the foam rubber. Please refer to
When the foam rubber 8 is squeezed, an elastic energy is conserved in the foam rubber for restoring the foam rubber to its original state. At a certain angle such as the angle shown in
During the compression operation of the foam rubber, the outer frames 51, 51′ will both quickly bound outward as shown in
It is therefore a primary object of the present invention to provide a mop having a handle and a foldable compression seat pivotally connected to bottom end of the handle via two links. The links are unlikely to swing so that the compression seat can stably keep in a straight state for mopping a floor.
It is a further object of the present invention to provide the above mop in which the compression seat is designed with a slidable structure. When squeezing the foam rubber of the mop, the compression seat will not make any sound.
To achieve the above and other objects, the mop includes a handle, a base seat fixedly disposed at a bottom end of the handle, and a compression seat mounted under the base seat. The compression seat includes a pivot block and two compression boards. Each compression board includes a fixed board and a slide board slidable relative to the fixed board. Inner ends of the slide boards are pivotally connected with two lateral sides of the pivot block respectively. A foam rubber is disposed under bottom faces of the slide boards. The inner ends of the slide boards can slide out of the inner ends of the fixed boards. Each slide board has a sliding dead end. The mop further includes two links each having a top end and a bottom end. The top ends of the links are respectively pivotally connected with two lateral sides of the base seat. The bottom ends of the links are respectively pivotally connected with the fixed boards. When shifting a shift lever mounted on the handle, the compression seat is driven and moved into the base seat to squeeze the foam rubber or moved out of the base seat to stretch the compression boards from the pivot block.
In the stretched state, the two links are tilted and a distance between bottom pivot points of the links is larger than a distance between top pivot points thereof. In addition, outer lateral faces of the links abut against two lateral sides of the base seat, which serve as support points for locating the links. Accordingly, when using the mop to mop a floor, the bottom ends of the links are unlikely to swing inward. Therefore, the compression seat can stably keep straight without easily moving into the base seat.
During the compression process of the foam rubber, the slide boards will slide out of the fixed boards to reach the dead ends. Therefore, the fixed boards are prevented from instantaneously bounding.
The present invention can be best understood through the following description and accompanying drawings, wherein:
Please refer to
The shift lever 30 is mounted on the handle 20 and can be pivotally rotated up and down.
Referring to
Top ends 51 of the links 50 are respectively pivotally connected with bottom ends of the seat sections 42 via pivot shafts 52. Bottom ends 55 of the links 50 are pivotally connected with the compression seat 60 via pivot shafts 56. The top ends 51 of the links 50 are positioned in the base seat 40, while the bottom ends 55 of the links 50 protrude out from the base seat 40.
The compression seat 60 includes a pivot block 62 and two compression boards 64. Inner sides of the compression boards 64 are respectively pivotally connected with two lateral sides of the pivot blocks 62 via pivot shafts 65, whereby the compression seat 60 is a bendable structure.
Each compression board 64 includes a fixed board 70 and a slide board 75. Lugs 71 are disposed on upper face of the fixed board 70 for pivotally connecting with the bottom ends of the links 50. Referring to
The mop according to the present invention further includes an foam rubber 80, which is elongated. Two connection plates 82 fixedly disposed on top face of the foam rubber 80. Buckles 84 are disposed on top faces of the connection plates 82 for latching in the latch holes 66 of the compression boards 64 as shown in
The drive rod 85 is preferably a U-shaped rod body. The drive rod 85 extends through a through hole 46 formed on the top section of the base seat 40. A bottom end of the drive rod 85 passes through the through hole 63 of the pivot block 62 of the compression seat 60 to connect with the pivot block 62. A top end of the drive rod 85 is connected with the shift lever 30. When shifting the shift lever, the compression seat 60 is driven via the drive rod 85.
In use, the shift lever 30 is shifted down as shown in
Referring to
Please refer to
It should be noted that the dead ends of the slide boards 75 are not limited to that of
According to the above arrangement, the links 50 of the mop have locating effect and are hard to swing inward the base seat. Accordingly, the compression seat 60 can keep straight without swinging or bending. Therefore, the mop of the present invention can be more conveniently and efficiently used to mop a floor.
Moreover, it can be known from
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.
