DESCRIPTION:
BRIEF SUMMARY
The present invention relates to the technical field of mop wringers.
Numerous mop wringers are known within the technique. Thus, reference is made to the following U.S. Pat. Nos. 688,613, 1,110,616, 1839,748, 2,099,217, 2,165,862, 2,299,777, 2,417,416, 2,544.937, and 3,441,973. Common to these known mop wringers are their inadequate and unsatisfactory operation. In the case of the known mop wringers, the squeezing pressure or wringing pressure is simply generated by the mechanical pressure, which an operator produces by means of a handle, which squeezing or wringing pressure is transmitted to a mop, which has previously been introduced into the mop wringer. Other technical solutions relate to the employment of springs for generating a pressure between mop squeezing or mop wringing rollers.
An object of the present invention is to provide a novel mop wringer, which makes it more easy for an operator to efficiently squeeze a mop, which has previously been introduced into the mop wringer, without having to generate an extremely high manual pressure. A further object of the present invention is to provide a mop wringer, which eliminates any risk of jamming of cooperating components of the mop wringer, such as cooperating teeth of toothed wheels and toothed racks of the prior art mop wringers.
As still further object of the present invention is to provide a durable and high-strength mop wringer.
An important feature of the present invention is the fact that the mop wringer may be made from a fairly small number of components. Other features, advantages and objects will be evident from the description below.
The above and other objects, features and advantages are obtained in accordance with the present invention by means of a mop wringer comprising: least one of which rollers is movable between an inactive position in which said rollers are out of contact with one another and in spaced apart relation and an active position in which said rollers are in contact with one another and pressed against one another so as to cause said roller bodies to be deformed and to generate a wringing pressure between said roller bodies, and at least one of said rollers being provided with a drive wheel for receiving rotational motion for causing said rollers to rotate in opposite directions when in said active position, and to a third position, and comprising a first and a second cam surface and a roller drive means, said first cam surface guiding said movable roller from said inactive position to said active position, when said actuator means is moved from said first position to said second position, said second cam surface locking said movable roller in said second position, when said actuator means is moved from said second position to said third position and vice versa, and said roller drive means transmitting rotational motion to said drive wheel, when said actuator means is moved from said second position to said third position and vice versa.
By the employment of an actuator means having a first and a second cam surface, the movable roller is smoothly moved from its inactive position to its active position and positively maintained in its active position while the roller, which is caused to rotate by the interaction between the drive wheel and the roller drive means, is caused to rotate. Thus, the roller drive means does not transmit any force to said drive wheel for maintaining the rollers in contact with one another and pressed against one another. The roller drive means transmits rotational power to the drive wheel exclusively.
In order to ensure that the movable roller is positively moved from its inactive position to its active position and further maintained in its active position while the rollers are rotated driven by the roller drive means, the housing of the mop wringer according to the present invention, preferably has rollers extending between opposite end walls and journalled at opposite ends of the rollers, and the movable actuator means preferably further comprises a pair of actuator means provided at respe
