Description

The The invention relates to an irritant spray device according to the preamble of claim 1.

Irritant sprayers of the type mentioned are, for example, from the DE 20 2006 004 268 U1 . DE 20 2006 000 889 U1 and DE 20 2006 008 367 U1 known. The known irritant spraying devices comprise a housing in which a pressure vessel, for example an irritant cartridge, is exchangeably received. The irritant cartridge may be filled with irritant, for example CS, OC or PAVA. On the irritant cartridge, a spray head is attached, which in turn comprises a spray nozzle. By depressing the spray head by means of the user's thumb, a valve integrated into the irritant cartridge is opened and the release of the irritant is made possible.

task The present invention is an irritant spray device to create the type mentioned, which with even greater Reliability can be operated.

These Task is accompanied by an irritant sprayer the features of claim 1 solved. Advantageous developments The invention are specified in subclaims. About that In addition, find important features for the invention in the following description and in the drawing, these Features both alone and in different Combinations may be important to the invention without being noted.

By the display device provided according to the invention a user of the irritant sprayer can at any time Determine if the pressure vessel is already operating been or not. This reduces the risk that a Irritant sprayer is used, which already half empty. Ultimately, this is the reliability improved in the operation of the irritant sprayer. It is understood that under the term "first commissioning" not necessarily a first removal of irritant from the pressure vessel to understand. To achieve the said advantage, it can also be sufficient, only a first "arming" of Pressure vessel or a first depression of the Display spray head.

In A first development proposes that the display device a plastically deforming in the change of state, breaking, tearing, peeling and / or permanently shifting Part includes. Such a display device thus operates mechanically and therefore very reliable. Furthermore Such a display device can be manufactured inexpensively.

A Further advantageous embodiment of the invention relates to a display device with a blocking element, which between pressure vessel and Spray head is arranged and the spray head first releases when a locking element of the pressure vessel is brought into the locked position. This ensures that for example during storage of the pressure vessel outside the case no accidental release is possible. Only when the pressure vessel in the housing is deliberately locked, the blocking of the spray head solved, which can be detected tactile by the user, because only then a depression of the spray head possible is. Such a display device is particularly effective as it in addition, an undesirable emptying of the pressure vessel prevented.

Around to ensure a lasting tactile indication and at Control also provides a reliable visual indication to allow at least one area of the blocking element plastically deformed during insertion of the locking element or to get broken.

A Another advantageous embodiment provides the spray head frictionally held sliding element which determines its position changed at a depression of the spray head. Such a sliding element can be very simple, for example, in two-component injection molding getting produced. With appropriate structural design also allows both visual and tactile Display. Another advantage is that only an actual Depressing the spray head a change of state the display device causes what the uniqueness of the display improved.

false readings are avoided and the durability of the display is improved, when the sliding element with the spray head over a breaking or tearing during an operation Material bridge is connected. Also an unintentional release of the Sliding element from the spray head is thereby avoided.

One U-shaped sliding element attached to a spray nozzle of the spray head, requires no changes at the spray head and may possibly even on previous Be retrofitted spray heads.

For a rod-shaped sliding element should, however, in the spray head be provided a bore through which the sliding element, however Especially good is what leads to the risk of false positives reduced.

By bündi in its second position substantially with the top of the spray head ges sliding element, the gripping of the top of the spray head is not affected by the user. In contrast, when the sliding element projects beyond the top of the spray head in its second position, a tactile perception of the state of the display device is additionally made possible.

The Uniqueness of the status display of the display device is through a color mark improved.

The Display device may further comprise a cover member, which before the first start - up an outlet opening of the Covering spray nozzle. The information of this display device is particularly significant since the ad is directly related with the removal of irritant via the spray nozzle he follows. As long as the cover still in place in his first position may be almost certainly It can be assumed that a withdrawal of irritant is still not done. In addition, with such a Display device particularly simple structural embodiments conceivable, which the additional cost of the display device be kept low.

A Fixing the cover in the first position by a Adhesive, such as adhesive, manufacturing technology is particularly easy and inexpensive. In the simplest case, that will Cover element at the first delivery of stimulant through the the spray nozzle exiting spray just torn away.

The Operational safety is increased in case of failure, if that Cover member includes a tab for manual removal.

One Remove the cover from the spray nozzle But also in a mechanical way in cooperation with a housing-side abutment section, whereby the spray nozzle and its environment of adhesives etc. can stay free.

A another embodiment of the display device sets a recessed Attacking section on the top of the spray head ahead, in which the user to operate the spray head intervenes. This can be covered with a cover, which then when the user with force on top of the Spray head pushes, tears and thus likewise indicates that a first startup of the irritant sprayer is done.

following Be embodiments of the invention with reference explained in more detail in the accompanying drawings. In the drawing show:

18 and 19 : Representations of a seventh embodiment of a display device.

An irritant sprayer carries in the 1a and 1b Overall, the reference number 10 , It includes a housing 12 for receiving a pressure vessel 14 and one on a delivery nipple 16 of the pressure vessel 14 attached spray head 18 , The pressure vessel 14 and the spray head 18 make up a total of an irritant cartridge 20 that only dashed and only in 1a is indicated.

The housing 12 includes on its top a hinged lid 22 who in 24 is articulated or pivotally mounted. The irritant cartridge 20 gets into the case 12 with hinged lid open 22 used and in the housing 12 by a locking element 26 secured in the form of a safety slide. This is in the in the 1a and 1b shown mounting position detachable in the housing 12 locked.

In the pressure vessel 14 is an irritant stored under pressure. As an irritant pepper, capsaicin, Pelargonsäurevanillylamid, CS or CN gas or the like come into question. For training purposes, the pressure vessel 14 also be filled with a neutral fluid, for example, with pure water.

When using the irritant sprayer 10 the user grabs the housing 12 and he slides his thumb between hinged lids 22 and spray head 18 so that the thumb is on the top of the spray head 18 rests. As a result, the hinged lid 22 something against the power of a not shown raised spring raised. With the remaining fingers of the hand the user reaches around the lower part of the case 12 , If a release of irritant is desired, the user presses with his thumb on a recessed and grooved actuating surface 28 of the spray head 18 , This will cause the spray head 18 to the pressure vessel 14 moved, causing the dispensing valve, which in the pressure vessel 14 is arranged, opens, creating an irritant beam 30 from a spray nozzle 32 of the spray head 18 exit.

That in the 1a and 1b shown irritant sprayer 10 has a display device, by which a carried out first commissioning of the irritant spray device 10 is displayed permanently. The display device can be designed differently. A first embodiment will now be described in connection with FIGS 2 to 4 explains:
The display device is a total of 34 designated. It comprises a blocking element 36 which is between an upper edge 38 of the pressure vessel 14 and the spray head 18 is arranged. The 3 and 4 are a view from below of the spray head 18 , It can be seen that the blocking element 36 a middle section 40 which is parallel to the spray nozzle 32 extends and in which an opening 42 is available. By means of this opening 42 is the blocking element 36 on a collar of the spray head 18 attached, with this with the tax nipple 16 of the pressure vessel 18 connected is.

To the middle section 40 are two blocking sections 44 formed in the manner of laterally projecting wings. The blocking sections 44 are with the middle section 40 each over a thin bridge of material 46 connected. At the projecting ends of the two blocking sections 44 is one to the bottom of the spray head 18 pointing nose 48 formed. The height of the projecting end of a blocking section 44 including the nose 48 roughly corresponds to the gap between the upper edge 38 of the pressure vessel 14 and the bottom of an outer edge 50 of the spray head 18 ,

The middle section 40 protrudes with its front edge something over the spray head 18 out. At this edge is also one of the pressure vessel 14 pointing away nose 52 molded, in the end region of a slot 54 is available. In this slot 54 is the spray nozzle 32 added. The depth of the slot 54 is chosen so that the spray head 18 for actuating the irritant spray device 10 continue sufficiently towards the pressure vessel 14 can be moved.

In 3 is also an area of the locking element 26 shown. It can be seen that this two lateral, in the longitudinal direction of the locking element 26 extending operating sections 56 having.

On the pressure vessel 14 are after filling it first, the blocking element 36 and then the spray head 18 placed. In this starting position are the blocking sections 44 in the in the 2 and 3 shown first position in which the noses 48 between the edge 50 of the spray head 18 and the top edge 38 of the pressure vessel 14 are arranged and in this way a depression of the spray head 18 towards the pressure vessel 14 prevent.

Now the irritant cartridge 20 in the case 12 used. For safe use of the irritant sprayer 10 must be the irritant cartridge 20 in the case 12 be secured. For this purpose, the locking element 26 from a first position in which there is the pressure vessel 14 releases (about 3 ), in the 4 shown pushed second position in which it is the pressure vessel 14 in the case 12 guaranteed. When moving the locking element 26 become the two blocking sections 44 from the operating sections 46 in the in 4 forced position shown, with this pivotal movement, the material bridges 46 tear down in part. In the in 4 shown second position of the blocking sections 44 are the noses 48 no longer between the outer edge 50 of the spray head 18 and the top edge 38 of the pressure vessel 14 but below one between the outer edge 50 formed free space of the spray head 18 , In this second position of the blocking element 36 can the spray head 18 to the pressure vessel 14 moved and thereby an irritant jet 30 to be triggered.

The in the 2 to 4 shown display device 34 works so mainly "tactile" in so far as the user at the impossibility of the spray head 18 depressing, can establish that a first commissioning in the sense of establishing a readiness to operate ("arming") has not yet taken place. By removing the pressure vessel 14 out of the case 12 In addition, he can determine the position of the blocking sections 44 also visually perceive.

Another embodiment of a display device will now be described with reference to FIGS 4 to 8th explained. In this case, it applies here and below that such elements and regions which are functionally equivalent to elements and regions of already described figures are usually not explained again in detail and bear the same reference numerals in all figures.

The in the 5 to 8th shown display device 34 includes a U-shaped sliding element ment 60 (see in particular 6 ), with a base 62 and two thighs 64 , The inner edges of the thighs 64 are as friction surfaces 66 designed. The clear width between the two thighs 64 is chosen so that the sliding element 60 in installation position in a tight fit on the spray nozzle 32 is attached by the spray nozzle 32 between the friction surfaces 66 the two thighs 64 is included.

In the in 5 shown starting position are the two legs 64 with their free ends with the spray head not pressed down 18 not over the top of the spray head 18 out, whereas the lower edge of the base 62 on the upper edge 38 of the pressure vessel 14 seated. Will now for a delivery of an irritant jet 30 the spray head 18 pressed, the spray nozzle shifts 32 between the two thighs 64 to the base 62 because of the sliding element 60 with the base on the pressure vessel 14 supports ( 7 ). Will the delivery of the irritant jet 30 finished, the spray head 18 relieved and he returns to the 8th shown starting position back. Due to the frictional engagement of the friction surfaces 66 with the spray nozzle 32 becomes the entire sliding element 60 with the spray head 18 in the initial or rest position of the spray head 18 taken.

How out 8th it can be seen, now stand the free ends of the two legs 64 over the top of the spray head 18 above. At this supernatant, the user can see that the spray head 18 a first time has been pressed. In addition are on the sliding element 60 colored markings 68 available ( 6 ), which in the in 5 shown starting position of the spray head 18 hidden in the in 8th However, the end position shown is free. These also help the user as an optical reference for confirming that the spray head 18 already been depressed a first time.

Another embodiment is in the 9 to 12 shown. In this are two rod-shaped sliding elements 60 present in the in the 9 and 10 shown unused starting position in corresponding holes 70 in the spray head 18 are recorded so that you in the figures upper end substantially flush with the top of the spray head 18 completes, whereas in the figures lower end of the rod-shaped sliding elements 60 on a closure plate 71 of the pressure vessel 14 supported. The sliding elements 60 are in the holes 70 held in frictional engagement.

Will the spray head 18 by a user for delivery of an irritant jet 30 Depressed for the first time, pushes in the figures upper end of the rod-shaped sliding elements 60 from the top of the spray head 18 out (cf. 11 ). Will the spray head 18 Released by the user, he returns to the in 12 shown starting position back. In this return movement, the two sliding elements due to the frictional engagement 60 from the spray head 18 taken. The supernatant of the rod-shaped sliding elements 60 over the top of the spray head 18 is a visual and tactile indication to the user that the spray head 18 has already been depressed at least once.

One to the 9 to 12 very similar embodiment shows 13 : In this, however, are the rod-shaped sliding elements 60 in the unused starting position in the respective bore 70 sunk so that after a first use they are substantially flush with the top of the spray head 18 lie. In addition, the two rod-shaped sliding elements 60 each over a thin bridge of material 46 with the spray head 18 connected. The material bridge 46 breaks when the spray head 18 Depressed for the first time and the two sliding elements 60 in the respective hole 70 be pushed up.

Another embodiment show the 14 and 15 : The display device shown there 34 includes a cover 74 which is prior to a first use of the irritant cartridge 20 of the irritant spray device on an annular end face 76 the spray nozzle 32 attached with an adhesive. The face 76 surrounds an outlet opening 78 ,

Will the spray head 18 Depressed for the first time, so by the irritant sprayer 10 an irritant jet 30 is delivered ( 15 ), the cover element 74 by the pressure of the irritant jet 30 from the frontal area 76 Torn away (arrow 80 in 15 ). It is therefore understood that the adhesive must be selected so that the pressure of the irritant jet 30 the cover 74 can carry away with security. Preferably, the cover is 74 produced as a thin film or as a thin paper element and carries a signal color. The user can thus be aware of the presence or absence of the cover element 74 visually recognize if the irritant cartridge 20 already been actuated and an irritant jet 30 has given or not. In one embodiment, not shown, is on the cover 74 a tab provided, with the cover if necessary 74 by hand from the face 76 can be solved.

One to the embodiment of the 14 and 15 similar embodiment is in the 16 and 17 shown: In this covers the cover 74 a T-shaped take rabschnitt 80 , and on the case 12 is a corresponding stop section 82 available. In the in 16 shown starting position is the driver section 80 from the stop section 82 a little bit apart. Will the spray head 18 for the delivery of an irritant jet 30 depressed ( 17 ), remains the T-shaped cam portion 80 at the stop section 82 of the housing 12 "Hang", causing the cover 74 from the frontal area 76 the spray nozzle 32 is solved. Is the cover element 74 from the spray nozzle 32 solved, it is in a "second position", it is still with the end face 76 the spray nozzle 32 connected, it is in a "first position".

Another embodiment show the 18 and 19 : This is in the in 18 shown unactuated starting position on the recessed and grooved actuating surface 28 , which may also be referred to as an "engaging portion", a cover member 84 with a tension section 86 curious; excited. The tensioning section 86 has a nominal break point 88 in the form of a perforation. When a user puts his thumb on the actuating surface 28 tried to grab the spray head 18 for the delivery of an irritant jet 30 depress, the tensile stress in the clamping section increases 86 such that the clamping portion at the desired tear point 88 tears ( 19 ). This is both a visual and a tactile indication that a user has already tried the spray head 18 depress.

It is understood that, for example, for redundancy reasons Almost all of the above embodiments combined can be.
