Water level signaler Description:

A device, shown in Fig. (L), which emits an alarm upon reaching a water level, preferably for bathtubs.

The state of the art is that one is limited to the experience of the run-in time and occasionally forgets to turn off the water. There are water regulation machines on the market that are directly connected to the water cycle and therefore expensive.

The invention is based on a simple and inexpensive solution in which an alarming attention alerting the desired water level. The solution is characterized by the features in claim 1.

In the following, a preferred embodiment will be described with reference to FIGS.

The device, shown in Fig. (L), is pressed against an inner side surface, for example a bathtub, with the suction cup (4) guided on the device in an articulated manner.

The device (1) can now, despite the adhesion of the suction cup (4), about the joint (4b) rotate vertically (la) or horizontally (lb) for activation and deactivation.

In the vertical position (la), Fig.l, the rising water, the wire spiral body (6c), which is located in a closed container (7), hoist upwards, so that the air pressure therein in the spiral space (7b) upwards in the memory spaces (8) and (9) may differ.

If now the device is twisted horizontally, Fig.2, eliminates the water pressure, the wire spiral body (6c) relaxes and expands the spiral space (7b) and sucked by its relaxation, the previously expressed air again.

When raising the wire spiral body (6c) through the water, by means of the surrounding container (7), upon reaching a certain water pressure, the inward wire end is pressed against a stromabnehmendes copper plate (6b), in turn via a cable (6a) the signal generator (5) activated.

The device can remain on the inside of the bathtub even if the water level rises due to the person being lowered, causing the device to sink into the water.

In this horizontal position no alarm is triggered despite the water pressure, because the water pressure in the same ratio on the air storage chambers (8) and (9) acts, so you can dive with the device in a horizontal position without triggering the alarm. 2 2 t · *

The device has two independent rooms.

A self-contained and sealed space (7) with the battery (6), the signal transmitter (5), the wire spiral body (6c) and the connecting parts (5a), (5b), (6a), (6b) and one, the isolated interior (7) surrounding outer space, which is also closed by the tube (3) and the caps (2), except for the water inlet opening (2b) and the outlet (2a).

At the opening (2b), the rising ambient water can freely penetrate and push the air-filled spiral space (7b) upward, toward the direction of the resistive copper leaflet (6b).

At the opening (2 a), the amount of air remaining in the outer space due to the rising water can escape unhindered. From the opening (2a) also exits the alarm signal.

The container (7) shown is airtight in the form of a condom with a node (7a).

The end of the condom with the knot (7a) is slightly stretched over the edge at the end of the tube (3) and guided through the tube opening (2c) back into the tube interior.

The cap (2) in FIG. 3 pushed over the tube (3) prevents the condom node (7a) from retreating, thereby leaving a pyramid-shaped air storage space (9) and it can also freely oscillate the signal transmitter membrane from the signal generator (5) Fixed concerns of the cap (2) at the end of the tube also increases the sealing of the condom.

The container (7) is with its content a little wider than the inner diameter of the tube. During assembly, the tube (3) for the introduction of the container (7) is pressed oval.

When released, the tube (3) relaxes and the container (7) sits tight enough.

This type of attachment allows in the event of a technical problem, such as an uncontrolled permanent alarm to stop it by knocking the device with the cap ends against an obstacle. In this case, the container (7) in the tube (3) slips down and crushes the wire spiral body (6c), so that the spiral wire end kinks or is pressed to the side and the current-decreasing leaflet (6b) no longer has contact. 3

Claims (1)

3 Ρύ \ f'c'M ί-protection claims: 1 A water level detector of the higher water pressure compared to the air pressure thereby exploits (Figure 4), that in a container (7) is a current-carrying wire spiral body (6c), with his in Spiral wire center aligned stripped wire end (6d) on a contact point (6b) meets as soon as the water pressure acting on the spiral space (7b), sufficient to trigger the alarm. 2 water level detector according to claim 1, characterized in that a wire spiral body (6c) on an electrically conductive leaflet (6b) pushes the current on a battery is glued forward and with the on the wire spiral body (6c) lying container (7) relative to the fixed battery (6 ) forms a depressible air space (7b). 3 water level detector according to claim 1, characterized in that the container (7) in the form of a condom is knotted at the end (7a) and the node via a pipe end (3), shown in Figure 3, guided around and through a hole (2c) in the tube (3) is inserted again and is also prevented by a tight-fitting cover in the form of a cap (2) in addition to sealing its withdrawal. 4 water level detector according to claim 1, characterized in that it is connected by means of a suction cup (4) which is attached to a vessel to be filled inner surface and with the water level detector in a rotatable embodiment (4b), so that the water level sensor in a vertical water pressure activating position , in Fig.l, and to a deactivating transverse position, Fig. 2, brought bez. can be twisted. 5 water level detector according to claim 1, characterized in that the container (7) with the internal battery (6) and the laterally bonded power line (6a) is wider than the tube inner diameter (3), which can only receive the container (7) when the tube (3) is pressed oval during insertion, whereby the container (7), without further attachment, permanently in the tube (3) is held. 4
