Stirring device for a paint pot, with modifiable functions, in a plastic material
View Patent ↗A stirring device ( 50 ) for fitting to measuring-out lids that include a central orifice and that can be adapted to cylindrical paint pots with a top opening. This device is composed of two parts in different plastic materials joined together by means of an assembly system ( 30 ), the first part being a modifiable, interchangeable drive system ( 10 ) mounted to rotate in the central orifice, and the second part being a stirring system of the shaft and stirrer-blade type ( 20 ) that can be adapted to the size of the pot.
1. A stirring device for mounting on a measuring-out lid that has a central orifice and that can be adapted to a cylindrical paint pot having a top opening, said stirring device comprising first and second parts in different plastic materials and joined together by means of an assembly system, the first part forming a drive system mounted to rotate in the central orifice of the lid, and the second part being a stirring system having a shaft and a stirrer blade having at least one stirrer blade dimensioned to fit within the paint pot,
wherein said drive system is a single-block part, and comprises a drive element, a shaft and a spigot extremity whose diameter matches that of the central orifice of the lid, wherein said drive element comprises a gearwheel,
wherein said spigot extremity is split at its end in the direction of its length, thus forming two parts whose ends each have a projecting rim directed toward the outside and dimensioned for attachment to the blade-type stirrer system.
2. A device according to claim 1 characterised in that the drive system is made from a noble material of the polyamide or polyoxymethylene type, and the blade-type stirrer system is made from a material of the polypropylene or polymethylene type.
3. A device according to claim 2 characterised in that the drive system, when it is in polyamide, includes an MSO 2 filler of the molybdenum bisuiphide type.
4. A device according to claim 1 characterised in that the blade-type stirrer system has at least two stirrer blades.
5. A device according to claim 1 , characterised in that the top end of the shaft of the blade-type stirrer system is of the hollow cylindrical type whose diameter, and the shape of the aperture, are matched to the diameter and shape of the extremity of the shaft of the drive system and has an opening whose size is matched to that of the projecting rim, allowing the end of the shaft to be click-fitted by moving the parts together in the aperture and inserting the projecting rims into the opening.
6. A device according to claim 5 , characterised in that the shape of the extremity of the shaft and of the hollow is not totally circular.
7. A device according to claim 1 , characterised in that the projecting rim has a thickness that is equal to or greater than that of the cylinder.
8. A stirring device for mounting on a measuring-out lid that has a central orifice and that can be adapted to a cylindrical paint pot having a top opening, said stirring device comprising first and second parts in different plastic materials and joined together by means of an assembly system, the first part forming a drive system mounted to rotate in the central orifice of the lid, and the second part being a stirring system having a shaft and a stirrer blade having at least one stirrer blade dimensioned to fit within the paint pot,
wherein said drive system is a single-block part, and comprises a drive element, a shaft and a spigot extremity whose diameter matches that of the central orifice of the lid, wherein the said drive element comprises a drive coupler,
wherein said spigot extremity is split at its end in the direction of its length, thus forming two parts whose ends each have a projecting rim directed toward the outside and dimensioned for attachment to the blade-type stirrer system.
9. A device according to claim 8 , characterised in that the drive system is made from a noble material of the polyamide or polyoxymethylene type, and the blade-type stirrer system is made from a material of the polypropylene or polymethylene type.
10. A device according to claim 9 characterised in that the drive system, when it is in polyamide, includes an MSO 2 filler of the molybdenum bisulphide type.
11. A device according to claim 8 characterised in that the blade-type stirrer system has at least two stirrer blades.
12. A device according to claim 8 , characterised in that the top end of the shaft of the blade-type stirrer system is of the hollow cylindrical type whose diameter, and the shape of the aperture, are matched to the diameter and shape of the extremity of the shaft of the drive system and has an opening whose size is matched to that of the projecting rim, allowing the end of the shaft to be click-fitted by moving the parts together in the aperture and inserting the projecting rims into the opening.
13. A device according to claim 12 , characterised in that the shape of the extremity of the shaft and of the hollow is not totally circular.
14. A device according to claim 8 , characterised in that the projecting rim has a thickness that is equal to or greater than that of the cylinder.
