Wrist-watch defense device

#1. Field of the Invention

#The present invention relates to a defense device capable of repelling potential assailants. More specifically, it relates to a device which is mountable on a wristwatch, and capable of ejecting on demand a spray of repellent gas such as to repel an incoming attacker. As such, the fields of self-defense and personal security are the most likely to benefit from the unique advantages of the instant invention.

#2. Description of the Prior Art

#Various other objects, features, and attendant advantages of the present invention will become more fully appreciated as the same becomes better understood when considered in conjunction with the accompanying drawings, wherein:

#FIG. 1 is a side view of a preferred embodiment of the invention showing the watch portion lifted from the gas chamber portion.

#FIG. 2 is a top plan view of the gas chamber with the interlocking mechanism for mounting the watch bottom.

#FIG. 1 shows watch 1 seated on ring 2 from the top. Ring 2 has a watch band connector 3 on diametrically opposite sides. The artisan will recognize that the watch band connectors 3 could as well be connected directly to an existing watch's sides and extend through appropriate cutouts in the ring. An aperture 4 with two bays B, best seen in FIG. 3, is formed in the bottom of ring 2 and permits insertion of matching lips or tabs 6 on gas chamber 5. Tabs 6 fit in bays B so as firmly fit chamber 5 to ring 2 by twisting the two elements a quarter turn with respect to one another. Protruding lips 6 are such as to fit through the cutout bays in 4 during insertion, and to be held in the locked position when the chamber is inserted from the bottom and rotated 90 degrees with respect to the ring.

#Pressurized gas is released from nozzle 7 by pushing trigger portion 12 of pin 8 so as to move nozzle 7 located on the opposite side. Arrows A1 and A2 indicate the direction of movement in normal operation. A return spring 9 returns the pin to its original position once the pushing force is removed. A safety button 10 prevents the accidental or unintended use of the device. Button 10 can be slid beneath trigger portion 12 of pin 8 in the direction of arrows A3. A pressure indicator 11 gauges the pressure level of gas supply remaining in the chamber.

#FIG. 2 shows the lips 6 of pressure chamber 5 and the trigger 12 as seen from the top. The jet spray pattern 14 exiting nozzle 7 can be seen as going to the left of the watch in the figure. This assumes of course that the watch is mounted on the left wrist for a right-handed individual. For a left-handed person, the jet will exit to the right. It is also possible to provide, under the scope of the present invention, a nozzle adjustable for either a right-handed or left-handed individual, by rotating the nozzle and providing two stop positions, one ejecting to the left, and the second one ejecting to the right.
