AI Technical Summary
Existing self-defense devices containing irritant gases are cumbersome to carry and dangerous due to their loose nature, often requiring manual retrieval in emergencies, which can lead to accidental loss or insufficient time for deployment.
A permanently attachable self-defense device with Velcro straps, holding multiple spray cartridges, that activates via a lever mechanism to sequentially or simultaneously discharge irritant substances through a camshaft system, ensuring quick and controlled deployment.
Provides a secure, quick, and controlled release of irritant substances, eliminating the need for manual handling and reducing the risk of loss or delayed activation.

Abstract
Description
[0001] Common self-defense devices containing irritant gases of all kinds are not normally carried at all times and are only taken out of a bag or other container in an emergency. This is very cumbersome and dangerous, especially if, for example, similar items are accidentally grabbed in a handbag. Or if there simply isn't enough time. Furthermore, a spray can or other loose device can easily fall out of your hands.
[0002] The present invention eliminates these circumstances, since the defense device can be permanently attached to the left or right arm. The invention is described below with reference to drawings: Fig. Figure I shows the defense device 1, which is preferably attached and fastened with Velcro straps (not shown) that are pulled through the tabs 2, 3, 4, 5 and 6 and fitted to the user's forearm. The defense device 1 can hold one, two, three or more commercially available 20-gram spray cartridges. Fig. III inside. These cartridges can be used in the defense device under the removable cover 24. In Fig. In section II, the positions of the cartridges are designated 8, 9, and 10. For example, in Fig. I and II 3 cartridges.
[0003] If the user is now in danger and can only defend himself with an irritant gas or other gas or liquid, he raises his right arm, for example, and operates the trigger lever 11 with his left hand in the following manner: The release lever 11 has a release lever 12. This is held in a secured position by a spring (not shown). According to the invention, for example, the slider 13 engages in the inner radius of the lever bearing 14. The release lever 12 actuates the slider 13 out of the detent in the lever bearing 14 via a connection (not shown).
[0004] If the user now turns the lever combination 11 + 12 forwards, for example, a camshaft 21, which runs coaxially in the cover 24, is turned by the connected lever combination 11+ 12.
[0005] The camshaft 21 has 20 cam lobes 22 per cartridge. By rotating the camshaft, these cartridges are moved longitudinally by the cam lobes 22 and, on the opposite side of the cartridge, exert pressure on the release valves 23 of the cartridges 20. These release valves 23 are pressure-tight, immersed in the distributor 15 at the valve outlet 23.
[0006] Depending on the rotation angle of the lever 11 + 12 and the angular position of the arranged cams 22 on the camshaft 21, the cartridges of number 1 to n are now actuated one after the other or together and thus triggered.
[0007] The spray medium from the cartridges is combined in the distributor 15 and emerges from the nozzle 16 as a jet or spray mist.
[0008] The size of the nozzle and the nature of the nozzle opening 16 determine the type of jet, range, or spray mist.
[0009] The lever 11+12 can be designed so that it either locks into place or springs back to its starting position.
