Description

Technical environment

[0001] The invention relates to a housing for a pressure vessel containing a defensive gas, which is arranged in a pocket or handbag. The housing comprises a holder for holding the pressure vessel with a push button that can be used to unlock the atomizer nozzle on the pressure vessel. The pressure vessel is securely integrated into the housing, with the housing having a nozzle opening that can be secured to an opening provided in the pocket wall. The housing is secured to the inner wall of the pocket via a compression fitting. State of the art

[0002] Defense sprays are known from the state of the art, used in police operations or for private self-defense. Such a defense gas is stored in a pressurized container equipped with an atomizer nozzle that can be activated by a push button to spray the defense gas toward an attacker, rendering the attacker incapacitated.

[0003] A problem with such devices or equipment is that handling such pressure vessels is often difficult, as they are often stored loosely in handbags or trouser or jacket pockets. If, for example, a dangerous situation arises, there is often insufficient access, so that the defensive gas cannot be used effectively due to the need to search for or keep it ready, as the pressure vessel cannot be immediately brought into an operational position.

[0004] From the prior art, for example, DE 10 2011 000 767 A1 discloses a device and / or apparatus for repelling an attacker using a defensive gas. This device comprises a pressure vessel with an atomizing nozzle that can be activated by a push button. The pressure vessel is located in a container designed as a bag or frame, which is integrated therein, with an opening for actuating the pressure vessel being arranged in the region of the bottom of the container.

[0005] The device and / or device described therein is particularly tied to a bag in which a so-called container is integrated and associated with the bag. However, there is a desire that the functionality, as described, for example, in DE 10 2011 000 767 A1, can also be used with different types of bags, in order to provide the use of a defense spray, whereby the actuation of the pressure container for the defense spray should be concealed and unexpected.

[0006] For example, from the prior art according to DE 10 2016 1208 850 A1, a design is known on which the invention is based, in which, due to the provision of a sleeve-like housing, it is possible for the pressure vessel for the defensive gas to be accommodated therein. The housing is designed as a holder for the pressure vessel with the release button in order to easily integrate the device into a pocket. This is achieved by the housing being able to be secured via its atomizer nozzle to an opening in the pocket wall. The sleeve-like housing with the pressure vessel is thus held against the pocket wall. By reaching into the pocket, the pressure vessel with the unlocked atomizer nozzle can be actuated via the push button in order to then spray the defensive gas unnoticed through the nozzle out of the pocket wall.

[0007] A disadvantage of this and the aforementioned prior art designs is that uncontrolled or unintentional spraying of the defensive gas can occur at any time when the atomizer nozzle in the housing is unlocked, because the push button can be activated from the outside due to its accessibility inside the bag or from the bag wall. This poses a particular problem if the bag is carelessly put down, or if there are unintentional collisions with people or objects, or even if children come into contact with the bag, causing the push button to be activated and the defensive gas to escape. problem

[0008] The invention therefore addresses the problem of developing a housing for a pressure vessel with defensive gas and with a push button for actuating an unlocked atomizer nozzle in such a way that it ensures secure handling in a pocket or the like, so that uncontrolled triggering of the atomizer nozzle via the push button is prevented. Solution

[0009] According to the invention, this problem is solved with the features of the main claim; advantageous embodiments of the invention emerge from the subclaims.

[0010] The advantages achieved with the invention are that, due to the provision of a modified housing for a pressure vessel containing defensive gas, which is arranged in a pocket or handbag, the safety when handling it is improved. This is because the housing according to the invention is equipped with an additional element which can be actuated from the outside to unlock or lock the pressure vessel stored therein. The element is in an indirect operative connection with the push button on the pressure vessel, so that a release position for the push button on the pressure vessel is only achieved after the pressure vessel has been unlocked, thus enabling the atomizer nozzle to be unlocked. This design advantageously prevents unintentional triggering or actuation of the atomizer nozzle solely by the push button.According to the inventive solution, the pressure vessel stored in the housing must first be unlocked before the push button can even be pressed. This design thus ensures safe handling of the defense device in a pocket or handbag.

[0011] According to a particularly advantageous embodiment of the invention, a hold-down device is provided in the housing, which, when the push button is pressed, interacts with the atomizing nozzle on the pressure vessel to release the defensive gas. The hold-down device is located directly above the pressure vessel and thus above the atomizing nozzle in the housing. The hold-down device is molded onto the upper wall of the housing and, when the push button is pressed, pushes the atomizing nozzle on the pressure vessel downward, releasing the defensive gas.

[0012] In an advantageous embodiment, the element for unlocking or locking the atomizing nozzle is a spring-loaded slide, the free end of which protrudes through an opening in the housing wall. This provides an additional actuating element that enables operation of the device, which contributes to increased safe handling. According to the further development, the slide is mounted so that it can be displaced horizontally transversely to the pressure vessel, with the spring arranged between the other free end of the slide and the inner housing wall. This allows the mounted pressure vessel to be unlocked by a simple pressing movement. The corresponding return movement to re-lock the device is then carried out by the preloaded spring.

[0013] Advantageously, the slider has a slit-like opening in the area of ​​the pressure vessel's atomizer nozzle, which allows the defensive gas to pass through to the housing opening. The slider therefore does not impede the escape of the defensive gas. According to a further development of the invention, the slider has a molded-on nose which, under the action of the spring, blocks the actuation of the pressure vessel above the push button. When the slider is actuated against the action of the spring, the nose releases the pressure vessel. This design makes it easy to either block or unlock the displacement movement or displacement path of the pressure vessel in the housing. When the slider is in the locked position, a portion of the nose rests against the upper edge of the pressure vessel, so that the displacement path of the slider is limited against the pressure of the spring.

[0014] In a further development of the invention, the pressure vessel can be snapped into a holder formed on the inner wall of the housing and is slidably mounted therein. The hold-down device is provided on the upper wall of the housing. When the push button on the opposite housing wall is actuated, it interacts with the atomizing nozzle, releasing the defensive gas. The hold-down device and the push button are arranged axially relative to the pressure vessel. The push button for actuation is mounted in an opening in the lower housing wall.

[0015] To accommodate the aforementioned elements or means, the housing is designed as a flat box. The pressure vessel with the push button is advantageously arranged centrally in the housing, with the slide and spring positioned perpendicularly to it in the upper region of the housing. The housing thus designed can be arranged in a pocket such that the slide and push button can be actuated via a flexible pocket wall. Markings for the slide and push button, for example in the form of labels, can be provided on the outside of the pocket wall. Description of the drawings

[0016] An embodiment of the invention is shown purely schematically in the figures and is described in more detail below, in which: Fig. 1 a view of an indicated pocket with opening where the housing is arranged, Fig. 2 a view along the section line A - A in Fig. 1 of the housing in the locked situation of the pressure vessel and Fig. 3 another view along the section line A - A in Fig. 1 Housing in the unlocked situation of the pressure vessel and Fig. 4 a view along the section line A - A in Fig. 1 without pressure vessel. Examples of implementation

[0017] The Fig. Figure 1 shows a schematic view of a bag 1 with a housing 2 arranged therein according to the invention. The modified housing 1 is designed for a pressure vessel 3 containing a defensive gas, as shown in the sectional views of Fig. 2 and Fig. 3. In order to improve the safety of the housing 2 arranged in the pocket 1 or handbag, the housing 2 according to the invention is equipped with a further element 4. The element 4 is actuated from the outside to unlock or lock the pressure vessel 3 stored therein. As can be seen from the overview of the Fig. 2 and Fig. 3, the element 4 is in indirect operative connection with a push button 5 on the pressure vessel 3, so that only after the pressure vessel 3 has been unlocked is the release position for the push button 5 on the pressure vessel 3 given. Unlocking of an atomizing nozzle 6, as shown in the Fig. 1 and in the Fig. 2 is only possible then.

[0018] This design advantageously prevents the unintentional triggering or actuation of the atomizing nozzle 6 by the push button 5. According to the inventive solution, the pressure vessel 5 stored in the housing 2 must first be unlocked before the push button 5 can be pressed to activate the atomizing nozzle 6. Equipping the housing 1 with an additional operating element 4 thus ensures safe handling of the defense device in a pocket 1 or a handbag.

[0019] According to a particularly advantageous embodiment of the invention, a hold-down device 7 is provided in the housing 2, which, when the push button 5 is actuated, comes into operative connection with the atomizing nozzle 6 on the pressure vessel 3 to release the defensive gas. Fig. 2, Fig. 3 shows how the hold-down device 7 in the Fig. 2 rests against the atomizing nozzle 6, whereby in the Fig. 3 the hold-down device 7 presses the atomizing nozzle 6 into the pressure vessel 3, which leads to the release of the gas, as shown in the Fig. 1 is indicated.

[0020] The hold-down device 7 is located directly above the pressure vessel 5 and thus above the atomizing nozzle 6 in the housing 2. The hold-down device 7 is formed on the upper wall 8 in the housing 2 and, when the push button 5 is actuated, presses the atomizing nozzle 6 on the pressure vessel 3 downwards, which, as already mentioned, results in the release of the defensive gas.

[0021] In an advantageous embodiment, the element 4 for unlocking or locking the atomizing nozzle 6 is a slide 10 mounted under the action of a spring 9. The front free end 11 of the slide 10 projects through an opening 12 in the lateral housing wall 13. Thus, a further actuating element is provided which contributes to the operation of the device from the outside for safe handling.

[0022] According to the training presented in the Fig. 2, Fig. 3 and Fig. 4, the slide 10 is mounted horizontally transversely to the pressure vessel 3. The spring 9 is arranged between the rear free end 14 of the slide 10 and the other lateral inner housing wall 15. Thus, the mounted pressure vessel 3 can be unlocked by a simple pressure movement with the finger. A corresponding return movement of the slide 10, in order to re-lock, is then carried out by the preloaded spring 9.

[0023] As can be seen in particular from the Fig. As can be seen in Figure 4, the slide 10 has a slit-like opening 16 in the area of ​​the atomizing nozzle 6 of the pressure vessel 3, which allows the defensive gas to pass through to the housing opening. The slide 10 thus does not impede the escape of the defensive gas.

[0024] According to a further development of the invention, recognizable in the Fig. 2, Fig. 3 and Fig. 4, the slide 10 has a molded nose 17, which, under the action of the spring 9, blocks the vertical displacement of the pressure vessel 3 via the push button 5. However, if the nose 17 is displaced by actuating the slide 10 against the action of the spring 9, the pressure vessel 3 is released for vertical displacement. Due to this design, the displacement movement or displacement path for the pressure vessel 3 in the housing 2 is either blocked or unlocked in a simple manner. In the blocked position of the slide 10, shown in the Fig. 2, a partial area 18 of the nose 17 rests against the upper edge area of ​​the pressure vessel 3, so that the displacement path of the slide 10 is limited against the pressure of the spring 9.

[0025] In further development of the invention shown in the Fig. 2, Fig. 3 and Fig. 4, the pressure vessel 3 can be snapped into a holder 19 formed on the housing wall and is slidably mounted therein. The hold-down device 7 is provided on the upper housing wall 8 of the housing 1. When the push button 5 on the opposite housing wall 20 is actuated, it interacts with the atomizing nozzle 6, thereby releasing the defensive gas. The hold-down device 7 and the push button 5 are arranged axially relative to the pressure vessel 3. The push button 5 itself for actuation is mounted in an opening in the lower housing wall 20.

[0026] To accommodate the above-described elements or means, the housing 2 is in the overview of the Fig. 1 to 4 is designed as a flat box shape. Advantageously, the pressure vessel 3 with the push button 5 is arranged centrally in the housing 2, with the slide 10 with the spring 9 being arranged vertically thereto in the upper region of the housing 2. The housing 2 thus designed can be placed in a pocket 1 as in the Fig. 1, can be arranged such that the slider 10 and the push button 5 can be actuated via a flexible pocket wall. Markings for the slider 10 and the push button 5, for example in the form of labels, can be provided on the outside of the pocket wall.
