A self-defense spray umbrella with a cane function

This creation is a stimulating pepper gas that can be sprayed from a distance. In the face of a sudden attack by a gangster, an umbrella or a cane can be used to resist the sharp weapon of the opponent. The gangsters and the elderly who are used to resist armed attacks can prevent wild dog attacks.

Traditional umbrellas or canes are easy to carry and can be self-defense. However, in the face of the sudden armed attack of the gangsters, although the traditional umbrella or cane can be used for self-defense, in the process of fierce confrontation, there is still a knife attack by the other party to cause life and physical injury. possibility. At this time, it is necessary to be able to spray the anti-wolf spray that is sprayed at a long distance before the gangster is not close to the body, 3 to 4 meters away. However, the spray dose of the conventional gas gun and anti-wolf sprayer can only be used for a short time, and the stimuli of the gangster's face are sprayed with irritating gas and liquid. If the gangster closes his eyes and covers his mouth and nose, madly holding a knife and a stick to slash forward, the gas gun and the anti-wolf spray cannot resist. For example, in a small space such as a mass transit vehicle or a KTV box or an elevator car, and only a single exit. If the gangsters were found to be trailing with the knife, the gangsters sprayed the pepper gas to make it invisible. However, the culprits will still use their knives and sticks to block the export and slash and slash. To leave the scene, it is necessary to slash the mob with a knife. At this time, if there is no umbrella to resist the sharp knife to defend itself, it is still extremely dangerous to the people on the scene. Moreover, the chili gas cans are usually small in size for easy carrying. The number of irritating spray cans that can be ejected is also limited, and the risk is still present after several sprays. Be sure to use an umbrella to defend against attacks. Therefore must be added [spicy Pepper gas cans and [Umbrellas and canes] combine the two into one. First, spray irritating gas and use an umbrella or a cane to protect yourself from the attack. And if you encounter a viper and beast while walking in the mountains, if you just hit the wind, the user only carries the traditional anti-wolf sprayer. The pepper gas sprayed by the headwind will also spray on itself, but it has not yet reached the function of defense but first hurts itself. Therefore, it is necessary to have the umbrella or the cane of the piece to complement the attack of the gangster or to drive away the viper and beast in the first time, and then wait for the opportunity to use the pepper gas to spray to the other side in the downwind to have the protection effect.

In view of the complexity and diversity of the society, major incidents such as robbing with knives or arbitrarily killing people by mass transit are frequent. It causes great social unrest and the gangsters may cause damage or death to the attacker when attacking at close range.

When the traditional cane, such as the old man, went out, when a group of wild dogs attacked unreasonably, it was inconvenient because the old man himself acted. He could not drive the wild dog with his cane and he would still be chased by wild dogs. If the olfactory function of the wild dog can be applied, and the pepper gas canister is installed in the cane, the pepper gas can be sprayed on the wild dog group in an emergency to make it unbearable and leave. You can avoid the danger of being bitten when the elderly go out or climb.

The function or dose of the traditional gas gun and anti-wolf sprayer can only emit irritating gas and liquid to the gangster's face for a short time. And the average person puts the pepper gas cans in the bag, which is easy to be confused with the cosmetic bottle and can be taken wrong in a critical situation. Therefore, in order to improve the above shortcomings, the application team developed a combination of [Chilli Gas Cans] and [Umbrella] or [Canes]. It can protect itself by using the first irritating chili gas, liquid combination, umbrella or cane to resist the other party's attack. Moreover, the walking stick and the umbrella are also easy to carry around. As in the front end of the umbrella After placing the pepper gas can, hold the tube underneath with one hand and push the pepper gas canister to spray the pepper gas or liquid. When the opponent is armed with a weapon but can't visually cover his mouth and nose, he can use the umbrella or cane to strike the other's weapon, so that the above shortcomings can be solved. Moreover, the creation of this piece is to cover the position of the capsicum gas tank installed in the tube under the canvas of the umbrella, so the appearance is also the same as that of the general umbrella. The advantages of the improvement, such as encountering a mob in a crowd of people, can open the switch in an instant to hold the tube by hand, pushing and spraying the pepper gas. In addition, the switch can be used to control the number and range of pepper gas ejections. In most cases, after many eruptions have been erupted, the umbrellas and canes can be used to poke the gangsters without smashing the passers-by. Moreover, after the umbrella or the plug at the front end of the cane is covered or locked, the user can be prevented from accidentally touching the switch and spraying the pepper gas, causing public troubles. It can prevent the rainwater from infiltrating for a long time, causing the pepper gas tank in the tube to rupture and rupture and overflow the pepper gas. Based on the above advantages, the article has an article that can be easily carried. It has a self-defense effect and can be integrated into daily life. Please refer to Figures 13, 14, and 15.

The above range can also be applied to telescopic sticks and self-defense sticks. It can be combined with an electric shock to become a self-defense spray electric shock stick, which helps to improve the function of the traditional electric shock device. Because the traditional electric shock device is easy to carry and powerful, it can be used to defend the gangsters. However, it is necessary to have a close-knit gangster to have an electric shock effect. If combined with this item, the same telescopic rod principle as this umbrella can be used. Outside the 3-4 meters, the gangster can spray the pepper gas at a long distance before he is close to the body. If the gangster is close to the body, he can use the high-voltage electric shock to shock the gangster. effect. If you can use this piece with a traditional electric shock device, you can reduce the possibility of injury caused by close attacks by gangsters. Therefore, if the above-mentioned electric striker is combined with the present, it can be a self-defense spray electric shock stick, and has the function of improving the traditional electric shock device. See Figure 16.

This creation uses the luggage trolley as a model because its diameter can be contracted. It can then be used to squeeze the pepper gas canister and eject the pepper gas. Developed a suitcase pull-type self-defense spray umbrella. The embodiment is as follows: First, as shown in the first figure, the first trunk A is used as the backbone of the umbrella of the present article. First, the second tube C is placed in the first tube B. Then, after the capsicum gas canister 4 is placed in the front end tube of the first tube B, the elastic member 2 is placed at the neck of the capsicum gas canister 4, and then Lock the screw cover 3.

Next, within the second tube C, the fixing element 8 is locked by means of a screw 6. It is then possible to cause the elastic member 5 to bounce the male member 7 against the bottom of the chili gas canister 4. In order to adjust its tightness margin, the pepper gas canister 4 will not vibrate up and down in the tube due to the gap. Moreover, the elastic members 2, 5 provided in the piece can be used for the user to pay attention to the other party when encountering a suspicious person. The user only needs to turn the screw of the screw to turn the grip of the grip 27 by hand, and then try to push a little bit forward, and feel the elastic force of the elastic elements 2 and 5 by the touch of the hand, and then it is known whether the switch has been Completely in place, can you push the pepper gas canister 4 forward immediately. It can be used to shorten the operation time and pre-defend action. If there is danger, it can immediately spray the pepper gas to the gangsters.

The anti-sucking element 21 is successively used, so that the second tube C does not fall off after being pulled back from the first tube B when the user pulls back. Further, under the second tube C, there is a screw rotating grip 27 which is pulled back and rotated by the user. Because the inner tube of the tube under the second tube C has an internal thread, when the screw thread under the screw rotating handle 27 and the internal thread in the tube of the second tube C are rotated and engaged with each other, the needle can be pulled down. Toggle 26. Before the hook 26 is not pulled inside the second tube C, the hook 26 is in a deflected state, and is combined with the screw rotating grip 27 downward. When it is extended forward, the foremost hook connection is hooked to the finger-type element 25. If it is pulled down, the hook 26 will appear in a straight line state, causing the front end of the finger-shaped element 25 of the "〉" shape to rotate into the tube, and the latch member 24 can be toggled. At this point, the user pulls open the plug 1 at the top of the first tube B, and then can hold and push with one hand. The second tube C below presses the capsicum gas tank 4 above the first tube B upward to spray the pepper gas for self-defense.

The lower part of the case is provided with a lower nest 29, and a screw sleeve locking element 30 is connected underneath to rotate the screw thread outside the first tube B to fix the lower nest 29 to open the piece, so that the piece has a general umbrella shade The function of rain cover. And when the rotation is released, the utility model can be used to allow the user to play the swing function required for the self-defense.

On the other hand, if the user opens the canvas with the umbrella open, and only needs to press the latch member 24 of the second tube C, the second tube C can be pushed forward to push the chili gas can 4, and The pepper gas is sprayed in front of the umbrella, and the operation process takes 2 steps for about 2 seconds. After the use, it is only necessary to hold the first tube B, and the other hand pulls the second tube C backward, and the elastic member 23 of the C in the second tube will eject the latch member 24 from the hole. The original hole location. The second pipe C can be returned to the first pipe B and fixed to the first pipe B, and the length of the original first trunk A can be restored, and the plug 1 is plugged to make it have the trunk function of the general umbrella. Please refer to the figures 1 and 2 .

And it is common in the society, because of overtaking, the car is holding a stick and hitting people. Therefore, in order to enable the user to protect himself when operating the umbrella in the driver's seat of the car in the event of a hazard. The canvas is not obscured to its own line of sight because of the need to open the umbrella, so it is necessary to modify the lower nest 29 and set the threaded lock element 30. After the above improvement, the front end of the umbrella can be protruded out of the window, and the pepper gas can be sprayed for self-defense. Please refer to Fig. 1, Fig. 3, Fig. 4, and Fig. 14.

Moreover, in order to avoid the second pipe C, the first pipe B is pushed forward to push the chili gas canister 4. Because of the two tubes After being squeezed against each other, if it is rotated, the latch member 24 cannot be inserted back into the original hole position, and the first tube B and the second tube C cannot be fixed. Therefore, at the junction of the first pipe B and the second pipe C, a length of a section is required, and the front and the back of the two pipes need to be flat, so that the mutual cooperation does not cause the two pipes to rotate, and the bolt components can be made more. 24 regression positioning. Please refer to Figure 1, Figure 3, and Figure 4.

In the continuation, the lower nest 29 is provided in the piece, and a screw sleeve locking element 30 is connected underneath. In order to avoid opening the umbrella and retracting the umbrella, the latch member 24 is encountered when it passes, and the latch member 24 is pushed back into the tube. Therefore, the length of the pipe at the lower end of the first pipe B needs to be reduced with the bolt member 24 so that the lower nest 29 and the screw sleeve locking member 30 can pass through the pipe diameter when it is pushed up or down. Squeeze into the latch member 24, see Figure 1.

In this case, in order to prevent the screw from rotating the grip 27 back and rotating. The hook 26 will follow the rotation and cannot be hooked over the finger-type element 25, so that the latch element 24 cannot be toggled. Therefore, the bottom of the hook 26 must be a round seat, which is attached to the inside of the hollow tube of the screw rotating handle 27, and is covered in the tube so as not to come out. When the user can pull the screw 27 and rotate the handle 27, the hook 26 will only move downwards, but will not rotate with the screw 27, please refer to the lower left of the figure 1 A partial view of the rod 26 and the screw rotating grip 27 is shown in enlarged view.

In this case, if an elastic member is placed between the neck of the capsicum gas can 4 and the screw cap 3, the elastic member 2 can make the nozzle of the capsicum gas can 4 with the screw opening relationship due to the elastic opening relationship. keep distance. In this way, it is possible to prevent the user from causing the nozzle of the capsicum gas canister 4 to be squeezing away from the screw cap 3 because it is suddenly moved by the fact that the user removes the rainwater when the umbrella is removed in rainy weather. Will This sprays out the pepper gas, causing inconvenience and trouble to the public. In the case, when the second pipe C is pressed forward to the bottom of the cap of the capsicum gas tank 4, the nozzle of the capsicum gas tank must be able to be caught inside the screw cap 3. In this way, the pepper gas can be ejected. Therefore, the internal structure of the screw cap 3 needs to be formed into a stepped shape and has a hole above it to allow the pepper gas to be ejected. After use, the plug can be plugged. Finally, the top of the second tube C of this piece must have a hole to allow the convex element 7 to pass, and then against the bottom of the chili gas canister to prevent it from vibrating up and down, please refer to Figure 1. As with the same principle as described above, the piece can also be used as a walking stick, a self-defense stick, a telescopic stick, and the like.

This is a model of the telescopic rod, which is an innovative self-defense spray umbrella and cane. The implementation is as follows: The structure of the second trunk D is first placed in the third tube E by the fourth tube F. After the capsicum gas canister 34 is placed in the tube of the front end of the three-tube E, the elastic member 33 is placed at the neck of the capsicum gas can 34, and then the screw cap 32 is locked. The fixing member 52 is locked by the screw 36 in the fourth tube F. The elastic member 35 is caused to spring up the convex member 51 against the bottom of the chili gas can 34 to adjust its tightness margin. The capsicum gas can 34 is not shaken up and down in the inside of the third pipe E due to the gap. Continuing, if the elastic member 33 is placed between the neck of the capsicum gas can 34 and the screw cap 32, the elastic member can keep the nozzle of the capsicum gas tank 34 safe with the screw cap 32 due to the elastic opening relationship. distance. It can be avoided that when the user shakes off the rain when it is raining, the nozzle of the pepper gas tank 34 is instantaneously squeezed out to the screw cover 32, and the pepper gas is sprayed, causing unnecessary trouble. See Figure 5.

Then, when the user first opens the pointed plug 31 and then rotates the fourth tube F, the tube expands and contracts. The component lower seat 39 is retracted and the upper circular arc-shaped opening and contracting member 38 is released to release it. The fourth tube F to which the telescopic element upper seat 37 is coupled can be pressed forward to press the bottom of the capsicum gas tank 34 above the third tube E so that the nozzle is pressed against the screw cap 32 to eject the capsicum gas. When the opponent is armed with a weapon but cannot observe the nose and mouth, use the umbrella to smash the weapon of the opponent. Please refer to Figure 5 and Figure 6. When the user finishes using the fourth tube F in the opposite direction, the lever of the lower member 39 of the telescopic element in the tube pushes the upper circular arc-shaped opening and contracting member 38. It is pushed out from the inside to the outside in the fourth tube F. The circular arc-shaped opening and contracting element 38 is caught in the third pipe E by expansion, and is fixed to the fourth pipe F. Make it an rib and have the function of supporting other components. Please refer to Figure 5, Figure 6, and Figure 7.

Incidentally, the screw cap 32 is capable of squeezing and jetting the capsicum gas in order to make the nozzle of the capsicum gas tank 34, and its internal structure is formed in a stepped shape with an opening at the upper side. In order to prevent the fourth tube F from falling off and sliding out during the operation, the diameter of the tube below the third tube E needs to be reduced and the expansion unit 39 in the fourth tube F is locked with each other. After the operation of spraying the capsicum gas, it is necessary to pull the homing and clamp each other to avoid the outflow. Please refer to the enlarged view of the middle part in the middle of the right side of Figure 5.

In the following description, the top end of the tube of the fourth tube F is required to have a hole for the convex member 51 to pass, thereby against the bottom of the chili gas can. Further, the fourth tube F needs to be hollow to allow the curved elastic member 40 to be fitted therein, and the lower nest 67 of the umbrella can be caught when the umbrella is stowed. In order to allow the umbrella to retract the canvas, the fourth tube F can be rotated to push the chili gas can 34. Therefore, the length of the curved elastic member 40 between its own button switch and the shutter that is hooked to the lower nest needs to be lengthened. And between the tail of the rib at the end of the umbrella and the grip, it must be kept at a certain distance. Thus, the user presses the curved elastic member 40 When the button switch is pressed, the flap that is hooked to the lower nest will not enter the tube. When the fourth tube F is pushed forward to the capsicum gas can 34, the button switch of the curved elastic member 40 is not caught in the lower nest. See pictures 5 and 7.

In addition, in order to prevent the user from obscuring the line of sight during operation, the vehicle has a thread above the fifth tube H, so that the spiral sleeve locking member 68 below the lower nest 67 can be locked in the fifth tube when the umbrella is opened. Above the H, this piece has the function of a general umbrella to cover the rain. Please refer to Figure 8 and Figure 10.

The foregoing principles can also be applied to the cane, see Fig. 11, Fig. 12, Fig. 13, and Fig. 15. Can also be applied to telescopic sticks, self-defense sticks, and above. It can be combined with the electric shock device 131 as a self-defense spray electric shock stick as described above, please refer to Fig. 16.
