Dosmetic cleaning device with pivoting squeezing plates

Abstract

The staff is joined to the central element of a base which comprises two lateral portions joined elastically by thin portions and by the co-molding of rubber layers to the central element; a fork member with a tubular extension is slidable along the staff and has S-shaped inner profiles to allow contact via rollers with the lateral portions of said base; a replaceable assembly consisting of a sponge layer bonded to rigid flat elements can be detached to the base and released therefrom. The staff is detachable.

1 . Domestic cleaning device comprising: a staff-type structure; joined to the end of said staff-type structure a central element of a base which comprises two lateral portions which are joined to said central element; resilient members that tend to open out said lateral portions; a fork member with a tubular extension which can be slid along said staff with the aid of a grip, said fork member having inner profiles for contact with the lateral portions of said base; on said base, means for attaching and releasing a replaceable assembly; said replaceable assembly consisting of a sponge layer bonded to rigid flat elements provided with means for interacting with means for attaching said assembly to said base and releasing it therefrom; the sliding of said staff-type structure with respect to said fork member causing said based to flex, against the elastic force which tends to spread it out, and consequently causing the flexing and squeezing of the sponge layer, characterized in that said based is made by molding with co-molded rubber layers to form elastic joints between said central element and said two lateral portions, the components of the synthetic resin base being connected with thin layers at the positions of said joints.  
   
   
       2 . Device according to  claim 1 , characterized in that each of the lateral portions of said based forms a seat for a roller, which can make rolling contact with the corresponding inner shaped profile of the fork member, to facilitate the squeezing operation by their contact with said S-shaped inner profiles.  
   
   
       3 . Device according to  claim 1 , characterized in that it comprises a sleeve which can be mounted onto and engaged with the lower end of the staff, said sleeve forming a seat for joining to said base and having an elastic catch which can engage slidably in a longitudinal slot of the tubular extension of the fork member, thereby limiting the longitudinal travel of said fork.  
   
   
       4 . Device according to  claim 3 , characterized in that it comprises a screw connection between the end of the staff and the end of said sleeve and an angular fastening for the operations of connecting the staff to the assembly of the device and releasing it therefrom.  
   
   
       5 . Device according to  claim 1 , characterized in that it comprises, as a replaceable component, the assembly with the sponge layer and the flat elements, these elements forming, on one side, strips and, on the other side, flexible fastenings for interacting with slots and with appendages of said base, and also forming stops interacting with ribs of the base.  
   
   
       6 . Device according to  claim 5 , characterized in that it comprises a screw connection between the end of the staff and the end of said sleeve and an angular fastening for the operations of connecting the staff to the assembly of the device and releasing it therefrom.  
   
   
       7 . Device according to  claim 1 , characterized in that it comprises, as a replaceable component, the assembly with the sponge layer and the flat elements, these elements forming, on one side, strips and, on the other side, flexible fastenings for interacting with slots and with appendages of said base, and also forming stops interacting with ribs of the base.  
   
   
       8 . Device according to  claim 2 , characterized in that each of the lateral portions of said base forms a seat for a roller, which can make rolling contact with the corresponding inner shaped profile of the fork member, to facilitate the squeezing operation by their contact with said S-shaped inner profiles.
