Description

Towel automation device telescopic.

Object of the invention

The present invention relates to a device that, adapted on a telescopic towel rail, causes the advance of it when closing the tap to which it is connected to be Used the towel comfortably. In this way the user does not have to pull the towel rail to get the towel. The performance of the towel rail is based on the towel bar moving towards the user by force exerted by a compressed spring previously and subject by means of an interlocking, which is released at the time of closing the tap by means of a piston that has been moved by the overpressure generated in the tap pipe that has been closed

Background

Several types of towel rails are known, fixed or mobiles, inside the mobiles we have the telescopes. These they are basically formed by two coaxial bars, one of smaller diameter fixed to the side of the sink, and the other of greater diameter than It slides over the previous one and it carries the towel. To catch the towel the user must pull the bar with the towel, bringing it closer to its position, and returning it to its original place at finish. The drawback of this towel rail is that the user, with wet hands, should take the towel rail and pull the same, with risk of drops falling to the ground.

Also within mobile phones we can find those of articulated type. These are made up of 1 or more bars fixed to the wall by one end by a hinge vertical, which allows it to be oriented to both sides.

Another shape is that of a ring attached to the wall through a joint. The towel hangs by passing it inside of the hoop.

Fixed towel rails can be in many ways different, the most common being horizontal bar parallel to the wall, attached to it at its 2 ends.

Description of the invention

The device of the invention aims to improve the operation of the telescopic towel rails. These towel rails they have the disadvantage that the user, once the tap, you must take it out of your housing to make use of the towel with wet hands, being able to wet the floor. With this device, once the tap is closed the towel rail will move a sufficient distance to comfortably use the towel.

The telescopic towel rail, going back to the bottom pushed by the user's hand, compresses a coaxial spring at the same, being locked in that position by a stop cross.

The release of the interlocking and, therefore, the Towel advance, is produced by closing the faucet of the sink to that is connected To do this, the so-called effect of water hammer that occurs inside the sleeve that brings the water to the tap when it is closed. This water hammer causes a momentary overpressure of water inside the pipe. To take advantage of this overpressure, it connects to the sleeve that the water conducts the tap to another hose, by means of an accessory type T, finishing this additional sleeve in a tube. This tube It has a sealed piston inside that can be moved in axial direction, although limited by an axially mounted spring, which stops at a flange of the tube. Overpressure pushes the piston, which advances a few millimeters, compressing the spring. He another end of the piston comes out of the tube, pushing the rod of the telescopic towel rail, releasing it from its interlocking. Upon release of its interlocking, the spring pushes the towel rail, which is left of Comfortable way within reach of the user. Once the towel was used, the user must push the towel holder again, returning it to its nailed position, ready to be used again.

Description of a preferred embodiment

The device described below is built around an L-shaped support piece (5). In a from the faces a perpendicular rod (4) or shaft of the towel rail. At the other end of the rod or shaft one is screwed stop piece (3), larger in diameter than the rod.

Coaxially to the axis is mounted the towel rail (1), with a diameter slightly larger than the top (3) and larger than that of the rod (4).

Between the stop 3 and the blind end of the bar towel rail (1) the compression spring (2) is mounted.

At the end of the towel rail (1) which is not blind, the cam part (7) is mounted coaxially, in diameter outer larger than the towel rail 1, and smaller inner diameter that the stop 3 to prevent the towel bar (1) from leaving the rod (4), but instead larger than the rod (4) to allow also radial play.

On the horizontal face of the support (5), two Drills allow mounting of two hollow cylinders (8, 9). These cylinders are connected by 2 sleeves (14, 15) to the hot water tap pipe (hot water hose 15), and  to the cold water pipe (sleeve 14), by means of 2 fittings type TE (16, 17).

Inside each of the cylinders (8, 9), a piston (10, 11) is placed, with axial movement inside the cylinder, limited by spring (12).

To ensure the tightness of the pistons in the inside of the cylinders, on the periphery of each piston is they mount two o-rings (13).

The operation is as follows:

The sink user pushes the towel bar (1), overcoming the force of the spring (2), until the cam (7), thanks to the fact that it also has radial play with the rod (4), it exceeds the interlocking tab (6). This tab retains the cam and by both the towel rail (1) locked in that position, with the spring (7) compressed.

On the other hand, the accessories of type TE's (16, 17), communicate the hot and cold water cylinders (8.9), by medium of cold and hot water hoses (14, 15), at pipes that bring hot and cold water to the sink faucet, by what they are always full of water with the network pressure.

This network pressure thus reaches the cylinders (8, 9), inside of which are the pistons (10 and 11). This pressure exerts force on the pistons, which at in turn compress the piston springs (12). The two together O-rings (13) that each piston has at its periphery prevent the Water leaks out of the cylinders outside. In this position, the end of the pistons (9, 10) that is outside the cylinders (8, 9), is very close, practically touching, the cam (7).

When the sink faucet opens, either the cold, hot water or both, the pressure inside the Open faucet pipe drops, reducing pressure on the piston or pistons (10, 11) to which it affects. The docks (12) of the affected piston or pistons, when lower pressure is exerted on these, they decompress, separating the outer end of the piston (10, 11) of the cam open tap (7).

When the user closes the tap open previously, due to the so-called water hammer effect, it is created in the water inside the tap pipe that has been closed a momentary overpressure, which lasts the time it takes to turn off the tap. This overpressure is greater than the pressure that It exists in the pipe when the tap is closed. This overpressure pushes the piston or pistons with great force (10, 11) affected by the closure of the tap. The piston then compresses the spring (13), while the outer end pushes the cam (7). To the push the cam (7), this is released from the tab of interlocking (6). At this time, the spring (2) pushes the bar towel rack (1), causing its advance, thus approaching the towel to the user.

After closing the tap completely, it restore the initial conditions, being able to start again the cycle.
