Abstract

Drain unclogger, characterized in that it comprises a piece (1) made of plastic material, preferably of frustoconical or approximately cylindrical shape, delimiting a lower opening, which has its perimeter surface in concentric rings (3) distributed along its height, as in a bellows, said perimeter surface being compressible when the user of the plunger (1) presses it downwards; having in its upper part a grasping means; and having coupled a rubber ring (2) to the last of said folds (3) of said piece of plastic (1), thanks to the coincidence of diameter of the inner hole (2a) of said ring (2) with the recess ( 3a) of the lower fold (3) of said piece (1); said rubber ring (2) slightly descending perimetral skirts that enable a tight closure of the plunger to perform the suction in the drain.

Description

Drain plunger.

Field of the Invention

The present invention relates to a desalination of drain pipes for use in toilets, sinks, showers, bathtubs and the like, providing a series of relevant and advantageous features that will be reported more forward, apart from others inherent to your organization and Constitution.

Background of the invention

In any home, it is often necessary to  use of systems or devices that allow unblocking of pipes or drainage pipes that are clogged with relative ease, for which various mechanical systems are known as chemists

The mechanical instruments to unclog drainage channels that are known are very varied, being the better known, those that consist of tools that perform a bellows suction When said tools are compressed and reduce their space inside act like a suction cup, creating by pulling them and expand again, a vacuum that sucks the drain by removing the elements that cause the obstruction of the ducts.

These instruments are usually made of rubber due to the high elasticity of said material that allows its easy compression, as for the fact that the elasticity of the rubber also allows a correct adaptation of the mouth of the plunger to the surface where the drain is, allowing a tight seal, which by expanding the plunger body will create a high level of depression or emptiness that will drive the materials that obstruct the drain to move towards the Exterior.

The same elasticity of the rubber has forced manufacture gripping handles with other material, such as wood, or of rigid plastic, creating the industry different means of coupling both in the manufacturing process and at home of the user to do the coupling of handle and bellows.

But even though rubber is a cheap material and with the one that works with ease, when treating the unblocking of products of wide domestic consumption, their sales are very price sensitive, which is why manufacturers have made different efforts to provide unblocking even more economical in its materials and for the simplicity of its manufacturing.

Another drawback of the known technique more used comes from its same training material, rubber. Saying material can be very sensitive to certain household products and detergents that attack it, which has an impact on the shelf life that They can reach.

Explanation of the invention.

The present invention develops a plunger of drains that in a simple and practical way comes to solve the problems mentioned above getting costs of considerably lower manufacturing as well as a shelf life remarkably longer.

Additionally, with the construction of the invention, a suction power that is not inferior has been achieved to the one provided by the unblockers with rubber bellows.

Specifically the plunger of the present invention has the particularity of comprising two parts factory assembled, of which one is made of material plastic preferably obtained by injection that forms a hollow cylindrical body and open at the bottom, being able to also adopt a slightly truncated conical shape, and which presents a series of concentric folds regularly arranged as bellows whose purpose is to increase flexibility.

The other part and that is incorporated into the last of The aforementioned folds is a rubber ring with perimeter skirt slightly downward that allows the set to close Watertight necessary for subsequent suction.

The fact that the main part of the plunger object of the invention is made of material plastic also gives you the advantage in the economy of matter premium and manufacturing simplification, longer life thanks to its greater resistance to external agents causing deterioration such as changes in temperature, humidity etc.

Said piece of plastic that forms the bellows It is topped off by a handle for comfortable handling of the plunger. Said handle is made in the same operation of molding that builds the main body of the plunger.

Brief description of the drawings

For a better interpretation of the invention, accompanies the present specification of some drawings in the which is illustrated, by way of non-limiting example, of a form of realization of the drain pipe plunger and the like object of the invention. In these drawings:

Figure 1 is a perspective view of the separate parts that make up the plunger object of the invention.

Figure 2 is a perspective view of the plunger object of the invention once assembled.

Description of an embodiment of the invention

The invention consists of a plunger of drains comprising a piece (1), made of material plastic in a single molding operation, creating a cavity bounded by a lower opening, which interior space is Collapsible at a reduced volume and expandable back to its position original, thanks to arrange its walls in the form of corrugations with concentric rings (3) that allow said walls to be compressed when the plunger user (1) presses with the same down.

A rubber ring (2) with a perimeter skirt slightly descending that is attached at the bottom or opening (2a) of the plastic part (1), allows the assembly make the seal tight to obtain the necessary vacuum for proper operation.

The mentioned plastic part (1) adopts, in the represented embodiment, the shape of a body hollow cylindrical slightly conical and open at the bottom, equipped with a series of concentric folds (3) regularly arranged as a bellows that increase its flexibility.

Said rubber ring (2) is coupled to the last of the mentioned folds (3) of the plastic part (1) fitting perfectly thanks to the hole diameter coincidence inside (2a) of the ring (2) with the recess (3a) of the lower fold (3) of the piece (1).

The flexibility of both the rubber ring (2) and the piece (1) of plastic material, the simplicity and ease of assembly of the plunger of the invention by providing it also of its main characteristic of economy and durability.

In the preferred embodiment, said handle of the plunger is made with a knob-shaped protrusion (4) located at the top of the piece (1), obtained in the same molding operation as the plunger body.

It is understood that in the present case they will be variables how many details of construction and finish do not alter, change or modify the essentiality of the invention.

Claims (2)

1. Drain plunger, characterized in that it comprises a part (1) made of plastic material, preferably of a conical or approximately cylindrical shape, delimiting a lower opening, which has its perimeter surface in concentric rings (3) distributed along its height , as in a bellows, said perimeter surface can be compressed when the user of the plunger (1) presses it down; having in its upper part a means of gripping; and bringing a rubber ring (2) coupled to the last of said folds (3) of said plastic piece (1), thanks to the coincidence of the diameter of the inner hole (2a) of said ring (2) with the recess ( 3a) of the lower fold (3) of said piece (1); said rubber ring (2) having slightly descending perimeter skirts that allow a tight closing of the plunger to perform suction in the drain. 2. Drain plunger according to claim 1, characterized in that said gripping means is in the form of a gripping knob (4).
