Embodiment Construction

[0053] image 3 , Figure 3A as well as Figure 3B , shows a system for anchoring a physical weight at an external location on a plastic molded tub for a washing machine that is not part of the invention. The anchoring system is based on the presence of a set of cylindrical divisible pins (40) obtained from the same material and the same molding process as the two conventional parts of the barrel, that is to say, the two The conventional parts are the conventional cylinder (1) and the corresponding front closing flange (2).

[0054] Each pin (40) is designed to be inserted upwardly from the bottom of the hole (21a) of the counterweight (21), and when the counterweight (21) is arranged relative to the outer wall of the barrel, the pin has a set of three regularly distributed Longitudinal notch (40a).

[0055] In particular, it should be noted that the hole (21a) of the counterweight (21) has the shape of a truncated cone facing the end of the lower cross-section of the cent...

Abstract

The present invention relates to an anchoring system of counterweights for washers and washer / dryer combos based on the presence of a plurality of tubular divaricable pins (40, 41,42) on the external walls of the plastic moulded tubs(l) that, after being inserted into through holes (21a) obtained on the said counterweights, are designed to receive suitable divaricating inserts (40b, 41b, 42b) to prevent uncoupling from the holes.

Description

technical field [0001] This patent application for industrial invention relates to an anchoring system for counterweights of washing machines and combined washer / dryers. Background technique [0002] The following brief description of the prior art will make the features and advantages of the present invention more apparent. [0003] refer to figure 1 , the current model of washing machines and combined washer / dryers is a plastic tub with a combined structure formed from two separate parts (1, 2) designed to be fixed by known types of The device is securely coupled and secured. [0004] The first part consists of a large concave cylinder (1) closed at one end by a bottom wall (10) with a central hole and connected to the back with a cylindrical nozzle (11) , said cylindrical nozzle (11) is designed to accurately receive a metal bearing seat having a substantially cylindrical shape. [0005] The second part consists of a flange (2) with a large central opening (20a) desig...
