Abstract

Pneumatically operated downloader. It consists of a sanitary arrester that includes, bell, gate and overflow tube, has an auxiliary float and a pneumatic device whose expansion selectively produces two amplitudes that determine the performance of the auxiliary float, or an articulated float in the bell that has a movement tilting and equipped with a crossbar that can be inserted in a step of the overflow tube. The bell has means for articulating said tilting movement, and the float is eccentric with respect to the axis of the overflow tube. Application in the manufacture of sanitary arresters.

Description

Pneumatically operated downloader.

The technical sector of this invention is the of sanitary arresters, of those used for unloading selective of the contents of the tank.

Indication of the prior art. Is known the technique of "double discharge" and consists of mechanisms that have a double actuation device. Sayings Discharge systems are generally based on mechanical impulses. They are pneumatic, especially intended for use by disabled people, based on large push buttons that can be pressed in bulk, with feet, elbows, knees, etc. Equally there is a history that the arrester acts pneumatically, producing a single download.

As for drive systems tire, and the same owner requested the ES U 189731 by pneumatic unloading device for tanks, ES U 216069 and ES U216070, whose orientation differs in essence from current invention.

Among the dual download devices, it find the ES 1037249 by discharge device for tanks of toilets, which consists of a drive unloader mechanic that has a large central body that houses two floats related by a common axis perpendicular to the axis of the overflow determinants of pressure clamping in a narrowing of the overflow tube.

The technique disclosed by the document above mentioned basically coincides with EP0727533 which it presents an equally mechanical device that is operated by traction on its central overflow tube around which it has a porch formed by two arms telescopically inserted in some complementary pieces, having a float in the tube overflow, and two floating parts in a bottom bell linked to a wedge-shaped device that favors the temporary interlocking of the overflow tube.

The owner of this application is also of the PCT ES / 02/0029 by double-click pneumatic button for toilet dischargers, which describes a push button device tire in which in a single apparatus comprises a device of double pulsation that allows the air flow through a single exit.

Also the invention relates to a system of vertical adaptation of the overflow tube. The technique used up to now it has been based primarily on the elimination of surplus of the overflow pipe, by means of a cutting instrument during installation. This does not allow the new extension of the tube anymore chopped up. Existing telescopic systems do not meet criteria of security and are criticized for their instability, because they admit movement between its two parts and with it variation in length of the tube.

The invention that occupies this description, is It consists of a downloader that is equipped with a double device download, partial and total, and also has a performance with the single button described in the patent of the same owner, which It is equipped with features that allow you to select an impulse minor or major determinant of partial or complete discharge respectively.

Said device is provided with a regulator of length that is formed by two telescopic parts joined between yes and fit in preset positions resulting in a solid union capable of being regulated successively.

In order to make clearer the explanation that will follow, accompanied by nine sheets of drawings that in thirteen Figures represent the essence of the present invention.

According to the structure that follows from the set described, the unloader comprises:

A 2-6 tube that can be adjusted to the appropriate length according to the shape of the cistern. Said tube arranges the length adjustment so that a tube lower 6 in its upper section, has staggered holes arranged outside, and another tube 2 has a pivot corresponding in the lower part of its inner part. In these conditions, the small turn of the part or tube 2 with respect to the another, the tube 6, allows to release, or block to run the Length regulator, even after the arrester is installed. The required tightness is guaranteed by the O-ring 7. The tube 2 externally has notches 35 along its entire length. Said notches are the same as those in tube 6. The notches 35 are liable to retain the float 4 which has some pivots 36. The notches are made on a reinforcement, of so that they do not weaken the tube but are made on a protrusion or thickening of the tube.

The float 4 arranged in the upper part of the Downloader. This is basically conventional. It regulates its sliding position on tube 2 and interlocking by pivots 36 cited on the external notches 3.

An actuator of the discharge. This is constituted by an annexed body, structurally a single body with body 8, which internally has a housing 10 of the pneumatic device

Said actuator and pneumatic device, is configured as an extensible body in a housing 30. The lung once fed by air or fluid, its length increases by the ring that has, which makes raise the body of the housing 10, telescopically over the previous one. The support arms 18 linked to the tube and by this to the top move the tube overflow determining the discharge.

The body 8 internally has a float 20. Said float is articulated in a tilting axis 21. Said axis is housed at a point of the body, eccentric with respect to to tube 6. Something shifted to the opposite side of the float with with respect to the axis, it has a cross bar 22. Said bar It has a stepped shape. The overflow pipe has a step 40 liable to be retained by said bar. The effort of the float float 20 forces rod 22 to stay below of step 40. The decrease in water determines the effect opposite, and the weight of the float whose upper part has a amount of water retained there, when tilting, releases the bar transverse 22 of step 40 of tube 6.

The partial discharge is determined by the floating of the upper buoy. In this case, the bar 22 does not reach to lock the step 40, which causes the body to fall rubber closure with tube 6 and the closure of the tank once the Water level has dropped below float 4.

The effect that water produces when starting discharge, leads to balance the level of the tank with the level of the overflow tube. Thus, there is a decrease in the water to the sink, an internal ascent through the tube. This force it gets to lock the bar 22 in the step 40.

The mechanism of discrimination between downloading partial and total discharge, in addition to the pulse pulse must be lower volume in the first case, you need a limit in the closing rubber. Thus, an auxiliary part has been arranged, in "L" shape, which has a small vertical movement, is is held by pivots 25, and which has a lower stop, slightly separated from its base, and an upper end 26 that reaches to overcome the bar 22.

The effort produced in lung 16 the maximum pulse of the button, determines the interlocking of the step 40 and bar 22. However, the suction effect that occurs at balance the inner level of the tube 6, is unable to overcome the limit that the lower limit presents, which allows the precise discrimination between one type of download and the other.

To provide greater stability to lung housing 10, widenings 41 are arranged which they are inserted through expansions 43, practiced in shape coinciding with those widenings. Cap 17 has practiced the passage for said housing 10 in sinuous form 44, so that it facilitates the course of the body 10 through the top. The widenings 41 constitute a limit or support on the tube 6 without limiting its movement, to prevent its destabilization due to the tensions it may generate, and the widening of the lung housing 10. The arms 18 may be reinforced 42.

An explanation of the mode of realization.

It is susceptible of industrial application in the manufacture of flushings for toilets.
