FR2479035A1 - Plunger for unblocking wash basins - has stem with twisted blade at bottom and handle at top - Google Patents

Abstract

The plunger unblocking a wash basin or sink is designed to remove the mass of hair mixed with soapy material etc., which often blocks the trap or pipe. It has a stem, with a blade at the bottom made of twisted strip, and with a handle at the top. Alternatively, the stem may be made of wire, terminating in a helically twisted bottom part, or a series of undulations.

Description

Technical area.

 The present invention relates to an apparatus intended to unclog drains from sinks, baths or sinks which are obstructed by hair or fibers amalgamated with sediments or residues of soapy water.

State of the prior art and drawbacks.

When the evacuation of a washbasin, bathtub or sink is blocked, you can disassemble the siphon which generally equips this type of evacuation but it is sometimes necessary to disassemble the support of the device to access the siphon (there is then risk of leakage if the seal has been damaged. In all cases, the operation is uncomfortable and requires manual skill.

One can also use the chemicals offered on the market, they are generally based on caustic soda, they are not always very effective, they are always of a dangerous use because their action is often accompanied by projections which can shine l The chemical reaction caused by these products sometimes causes the formation of a plug which must be removed using a tool.

The use of these products is expensive
Problem.

The means described above do not allow to quickly and easily unblock the obstructed evacuation
Statement of the invention.

The device according to the invention makes it possible to avoid these drawbacks; it consists of a blade twisted at one of its ends, the other end possibly being terminated by a handle which can have a shape of a handle. basket; another embodiment consists of a wire, one end of which is folded in the form of a wave, the other end being terminated by a handle which may have the shape of a ring.

Solution to roblèrne, avahtaes and industrial results
The main advantage lies in the elimination of dismantling the siphons and in effective cleaning without the use of chemicals.

The device can be reused an unlimited number of times.

The invention will be better understood with the aid of the following description which gives two nonlimiting practical examples thereof and which are illustrated by the accompanying drawings.

Brief description of the figures.

Figure 1 is a front view of the apparatus formed from a thin blade showing the twisted lower part and the operating rod.

Figure 2 is a side view showing the twisted lower part and the handle disposed at the upper part.

FIG. 3 represents a variant of the apparatus produced from a wire of circular section, the active part of which is folded in a series of semicircles forming a wave; the upper part 8 is terminated by a handle.

Description of two embodiments.

The device identified by 7 and 2 consists of a thin metal blade, possibly treated against corrosion, or plastic. The twisted lower part is obtained by deformation of the material or by molding
The dimensions of the device are such that the twisted part can be engaged in the holes possibly forming a grid in the bottom of the bowl containing the liquid to be discharged.

The length of the rod is sufficient to allow the plug obstructing the flow to be reached. The device shown in 3 is a variant in shape but proceeds from the same technology.

Operation
After having possibly lifted the drain from the bowl, the flow of which is blocked, the twisted lower part of the device is engaged from top to bottom in the obstructed area of the evacuation duct of the sink, sink or bathtub. .

A rotational movement is then printed on the device; the hair, fibers and detritus or sediments are wrapped around the twisted part.

 I1 then suffices to exert a traction from bottom to top on the rod using the handle to extract the sediments, fibers and hair thus wound around the device.

The conduit being thus opened, the sanitary apparatuses are again usable.

The hair, fibers and sediments are removed from the twisted part of the device which is again ready for operation.
