Definitions

the invention relates to an eye shower for use in laboratories, workshops, training facilities and rooms where there is a risk that accidents with caustic solutions such as acids and alkalis or with gases contaminate the eye area of people due to carelessness.
the water fittings directed downwards into a basin are extremely unfavorable, especially when the contaminated person is on his own at the time of the accident and can no longer make out exactly how far away the eyes are from the water outlet.
Such an eye shower belonging to the prior art is designed, for example, in the form of a kind of horn shower, that is to say the outlet consists of two curved tube ends which extend upward away from the inlet and whose distance from one another approximately corresponds to the eye distance of an average person.
Such eye showers can either be installed stationary over a basin or at the end of a flexible hose.
the valve is operated using a manually actuated element next to the shower.
a shower arm provided with an outlet nozzle with a stationary key actuation on the drain basin as an eye shower.
a shower arm with a shower head is used on a flexible hose, the other end of which is attached to the outlet of the fitting housing, on the other hand the eye shower is also inserted into the fitting housing in a stationary manner or by means of a holder is plugged into the housing, the shower can be used both as a stationary shower and as a removable hand shower, whereby due to the special locking of the shower arm on or within the fitting housing, any actuating element, i.e. the triggering of the showering process with a handle or button, can be omitted .
the two insertion positions of the shower arm within the fitting housing are determined by axial displacement of the shower arm, i.e.
the closing position of the fitting is defined by a first grid lock and only by Further pressure on the shower head overcomes this closed position, the shower arm is pushed axially further into its holder and an end position is reached as the open position.
two grid locks for two different swivel positions are also conceivable the shower arm or two different rotary positions. The only thing that is decisive is that the injured person blindly grabs the shower head either automatically by simply pulling it out of its holder or presses or swivels it by pressing the shower head once and thus triggers automatically.
the servo control of the main valve via an auxiliary valve represents a particularly safe mode of operation, whereby the control of the main valve via the auxiliary valve by means of a counter-pressure chamber, which can be filled via a pressure compensation hole or emptied via an emptying hole, can work according to the known membrane principle in an advantageous embodiment.
the shower head can be equipped with one or more jet regulators, it being advantageous to arrange at least two jet regulators in such a way that they enable both eyes to be rinsed simultaneously with associated facial areas.
the cross-sectional view according to FIG. 1 shows the structure of the fitting with the fitting housing and shower arm with shower head in detail.
the base plate 5 can be attached to the laboratory wall above a drain of a wash basin or at such a basin and it in turn forms the attachment for the fitting housing 1.
the water inlet 29 which opens into the fitting housing 1 as a connecting piece is in direct connection with the drinking water line.
the inlet 29 is equipped with a strainer 4.
the fitting housing 1 here consists of a valve housing part screwed onto the base plate 5 and the housing part 3, which receives an adapter plate 2.
a main valve 6 is clamped, which can be actuated via an auxiliary valve 9, in a manner as can be seen more clearly in detail in FIG. 3.
the diaphragm principle of known solenoid valves is used, for which the main valve 6 separates the valve chamber 22 from a back pressure chamber 23 and seals the water-carrying chamber inside the valve housing part in the closed state.
a plunger or plunger 7 is axially displaceable and received centrally within a bore through the adapter plate 2 and is axially displaceably mounted therein.
the plunger 7 is provided with an annular groove, from which an O-ring 8 is received, so that water from the valve area even when the plunger is axially displaced within the adapter plate 2 cannot exit here.
the end of the plunger 7 opposite the valve abuts against the outer circumferential surface of a shower arm 12 inserted into the fitting housing 1.
the other end of the plunger 7 carries the auxiliary valve seal 9 which, when the plunger 7 is pressed, results in the first latching position or rest position in FIG the shower housing inserted shower arm sits on the auxiliary valve seat 24 and thus closes.
the auxiliary valve seal 9 is positively connected to the plunger 7.
Fig. 1 shows the first insertion position, that is, the eye shower in the rest position or closed state.
the outer diameter of the shower arm 12 increases in the region of the conical diameter extension 27, so that the The shower arm 12 can only be pushed further into the housing 3 with additional, but sufficiently low, effort.
This additional axial displacement is limited by the stop 28 and this pressed-in, that is to say the axially additionally shifted downward position of the shower arm 12 defines a shower position in which the water inlet is open, as will be explained in more detail below.
the shower arm 12 is thus held in the housing 3 exclusively by the two clamps 10 encompassing its circumference and thus its insertion state is also clearly defined.
the shower head 14 is screwed onto the shower arm 12 at the upper free end by means of an O-ring 30 in a watertight manner.
the screw 16 holds the shower base 15 on the shower head housing 14, the connection being established via an insert 17.
the outer peripheral surface of the shower head is protected against mechanical damage by means of an O-ring 18.
One or more jet regulators 19 are provided in the shower base 15, into which the quantity regulators 20 are integrated and fastened by means of threaded rings 21.
the shower arm 12 is connected to the outlet of the main valve in the valve body 1 via a spiral molded hose or flexible hose 13.
the flexible hose 13 can be wound around the housing part 3 of the fitting in the form shown and can thus be removed easily and without tangling when the shower arm 12 is removed from its holder within the fitting housing.
FIG. 1 The rest or closed position of the valve is shown in Fig. 1.
the shower arm 12 is pushed so far into its holder within the fitting housing that the upper clamp 10 is still below the conical diameter widening 27.
a bevelled annular groove 31 in the circumference of the shower arm 12 is located between the two clamps 10 and above the effective area of the plunger 7.
the non-positive contact of the upper clamp 10 in the circumferential area below the conical diameter widening 27 ensures that the shower arm 12 cannot slip into the fitting housing unintentionally or by its own weight.
Fig. 1 further shows in connection with Fig. 3 that in the illustrated rest position or closed position of the plunger 7 presses the auxiliary valve 9 on the auxiliary valve seat 24, so that the main valve 6 remains closed against the open position in Fig. 3. Since the same static pressure acts through the connecting bore 25 of the main valve 6 in the valve chamber 22 and the back pressure chamber 23, but the area of the main valve 6 is considerably larger than that below the main valve, the main valve is pressed onto the valve seat, so that the water flow from the inflow 29 is interrupted towards the flexible hose 13.
the watercourse is opened from the inlet nozzle into the fitting to the shower head whenever the plunger 7 can move to the right in the axial direction from the position shown in FIG. 1, that is to say as shown in FIG. 3, the auxiliary valve 9 moves away from the valve seat 24 takes off.
the water pressure in the back pressure chamber 23, corresponding to the line pressure, pushes the plunger outwards when the plunger can move freely, this displacement being limited by a stop of the auxiliary valve seal.
the auxiliary valve seal 9 in the form shown in FIG. 3 lifts off from the auxiliary valve seat 24, so that the water present in the back pressure chamber 23 can escape via an emptying bore 26 into the unpressurized space of the water outlet.
the water pressure in the back pressure chamber is reduced accordingly.
jet regulators 19 are provided in the shower head 14 and arranged on the shower base 15.
Flow regulators 20 are integrated in the jet regulators 19, so that the volume flow given per unit time via the shower head remains constant irrespective of the flow pressure in the water pipe and thus also the jet height and the jet pattern in its homogeneous distribution.
the water flow is terminated by pushing or snapping the shower arm 12 into the clamps 10 after pulling out the shower arm into the position shown in FIG. 1 or, if the shower arm was previously removed, by inserting it into this position. Now the shower arm 12 presses the plunger 7 and thus the auxiliary valve seal 9 in the direction of the auxiliary valve seat 24, so that the auxiliary valve is closed. The drain hole 26 is then closed again.
the back pressure chamber 23 is filled via the connection bore 25 as a pressure compensation bore until pressure equality in the back pressure chamber 23 and the valve chamber 22 is reached.
the main valve 6 lowers on the valve seat due to the greater effective force above the main valve 6 and the biasing force with which the clamps 10 pull the shower arm 12 into the holder.
the water flow is interrupted.
