Description

Technical Field

[0001] This invention relates to the field of umbrella technology, specifically to a multifunctional riot control umbrella. Background Technology

[0002] Umbrellas, as the most common rain and sun protection tools in daily life, have maintained their basic structure for centuries. Traditional umbrellas mainly consist of an umbrella canopy, ribs, shaft, and handle. The shaft is the core of the longitudinal support. The upper canopy is fixed to the top of the shaft, while the lower canopy slides onto it. Multiple ribs are hinged at one end to the upper canopy and extend outwards at the other end to support the canopy. Support ribs are hinged at one end to the lower canopy and at the other end to the middle of the ribs. The handle is located at the bottom of the shaft for the user to grip. In use, the user pushes the lower canopy upwards along the shaft, which in turn expands the ribs outwards via the support ribs, causing the canopy to tighten and provide shade. To close the umbrella, the user pulls down the lower canopy, causing the ribs and canopy to close due to their own elasticity and structural linkage. Based on this, in order to meet the special needs of the security field, in recent years, riot control umbrella equipment with protective functions has emerged, which uses umbrellas as carriers. Certain improvements have been made to the umbrella surface materials and the strength of the umbrella ribs, in order to provide police officers with a highly concealed and easy-to-carry protective tool in daily duty.

[0003] However, there are currently no mature products or technical solutions for combining tear gas sprayers with umbrellas. Simply hanging the tear gas bottle on the outside of the umbrella handle or the edge of the umbrella surface not only affects the overall aesthetics and ease of use of the umbrella, but also makes it easy to accidentally touch or leak during carrying. In addition, the spray direction is greatly affected by the wind and is difficult to control precisely. Summary of the Invention

[0004] To address the shortcomings of the existing technology, this invention provides a multifunctional riot control umbrella, aiming to solve the technical challenge of organically integrating tear gas spray functionality with a folding umbrella body. By embedding the tear gas canister within the handle and guiding it to the nozzle at the top of the umbrella via a flexible tube inside the shaft, coupled with a one-handed press-to-trigger mechanism, it achieves deep integration of the tear gas spray function with the folding umbrella body. This allows the riot control umbrella to maintain a foldable and portable appearance while also possessing concealed carrying capabilities and tactical effectiveness for both offense and defense.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-functional riot control umbrella, comprising a riot control umbrella body, wherein the bottom surface of the umbrella shaft of the riot control umbrella body is provided with a hollow handle with one open end, and the bottom surface of the umbrella shaft of the riot control umbrella body passes through and extends out of the closed end of the hollow handle, wherein a detachable press-type tear gas bottle is provided inside the cavity of the hollow handle, and an internally threaded sealing cap is provided at the open end of the hollow handle to close the open end of the hollow handle;

[0006] The hollow handle has a push-button switch on one side of its outer wall to control the start and stop of the press-button tear gas bottle. The top surface of the riot umbrella body has a window-breaking cone that is inserted through an L-shaped groove locking connection structure. The inside of the window-breaking cone is a nozzle for spraying tear gas. The fluid outlet of the push-button switch is connected to the input end of the nozzle through a hose.

[0007] Furthermore, the L-shaped groove locking connection structure includes an L-shaped groove located on the inner wall of the top surface of the riot umbrella body, and a locking block located on the side wall of the window break cone insertion end and corresponding to the L-shaped groove.

[0008] Furthermore, the input end of the nozzle is located on the bottom surface of the window-breaking cone insertion end, and the input end of the nozzle is a tapered insertion pipe.

[0009] Furthermore, the push-button switch includes a translation slider that is fitted onto the outlet of the push-button tear gas bottle and has several inclined surfaces, and a pressing block that corresponds to the inclined surfaces of the translation slider and passes through the side wall of the hollow handle. The interior of the hollow handle is provided with a limiting groove that restricts the translation slider to slide only along the axial direction of the hollow handle and is cross-shaped.

[0010] Furthermore, the two side walls of the translation slider are provided with ear plates corresponding to the limiting grooves.

[0011] Furthermore, the top surface of the pressing block is provided with anti-slip texture, and the bottom surface of the pressing block is provided with a slope groove corresponding to the slope of the translation slider.

[0012] Furthermore, the sliding slider has a slider channel inside for transmitting the spray output from the press-type tear gas bottle, and the output end of the slider channel is a tapered pipe. The slider channel is connected to the input end of the nozzle through a hose, and the hose is located inside the umbrella pole of the riot control umbrella.

[0013] Furthermore, the press-type tear gas bottle is a tear gas bottle with a spring-loaded reset nozzle structure.

[0014] Furthermore, the canopy of the riot control umbrella is made of cut-resistant fabric coated with a PU film.

[0015] Furthermore, the umbrella ribs of the riot control umbrella body adopt a two-fold design, and the ribs around the umbrella pole of the riot control umbrella body do not contact the umbrella surface.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: The present invention achieves a high degree of integration between the tear gas spraying function and the umbrella body by detachably embedding the tear gas bottle in the hollow handle and leading it to the nozzle at the top of the umbrella through the internal hose of the umbrella shaft, without changing the appearance and portability of the umbrella; the inclined slider mechanism of the push-button switch directly converts the pressing action into a squeezing trigger, realizing one-handed one-button rapid spraying, which stops when the hand is released; the design of the spraying direction at the top of the umbrella being consistent with the protection direction of the umbrella surface allows the user to obtain effective shielding from the umbrella surface while spraying tear gas, reducing wind interference and avoiding exposure of oneself.

[0027] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only used to illustrate the present invention and should not be regarded as limiting the scope of the present invention.

[0028] like Figures 1 to 9 As shown, the present invention provides a multifunctional riot control umbrella, including a riot control umbrella body 1. The riot control umbrella body 1 has the basic structure of a conventional umbrella, including components such as an umbrella canopy, umbrella ribs, umbrella pole, upper nest, and lower nest. The umbrella pole is the longitudinal support core, the upper nest is fixed to the top of the umbrella pole, and the lower nest is slidably fitted onto the umbrella pole. One end of multiple umbrella ribs is hinged to the upper nest, and the other end extends outward to support the umbrella canopy. One end of the support ribs is hinged to the lower nest, and the other end is hinged to the middle of the umbrella ribs. This structure is consistent with the opening and closing principle of conventional umbrellas.

[0029] When in use, the user pushes the lower nest upwards along the umbrella shaft, which in turn expands the umbrella ribs outwards through the supporting ribs, causing the umbrella canopy to tighten and form a shield. When closing the umbrella, the user pulls down the lower nest, and the umbrella ribs and canopy close up under their own elasticity and structural linkage.

[0030] Based on this, the present invention endows the umbrella with multiple defensive functions through a series of structural improvements. The umbrella surface of the present invention uses a cut-resistant fabric coated with a PU film material, which has both knife and axe protection and rain protection functions. When encountering knife cuts or axe chop, the cut-resistant fabric layer can effectively prevent the blade from penetrating, while the PU film layer provides protection while also providing rain protection. The umbrella ribs adopt a two-fold design, with a hinged folding joint set in the middle section of the umbrella ribs, so that each umbrella rib can be folded inward, thereby significantly shortening the length of the entire umbrella. After folding, the umbrella can be put into the police officer's tactical belt for easy carrying, without interfering with tactical actions such as arrest and running, and without causing tension among the public. In addition, the umbrella ribs also adopt a reinforced structural design, and the umbrella ribs around the umbrella pole are structurally designed not to be directly connected. The canopy is connected to the ribs through a gap, with the canopy indirectly attached to the ends of the ribs via connectors such as umbrella beads, rather than being attached to the entire length of the ribs. The advantage of this structure is that when the canopy is struck by a knife or axe, it will indent inwards and come into contact with the ribs. However, since the ribs are not in direct contact with the canopy under normal conditions, the external force is not directly transmitted to the ribs, effectively preventing the ribs from being directly cut off. Furthermore, the connection between the canopy and ribs uses a special structural stitching method, such as sewing reinforcing rings along the edge of the canopy and placing them on the ends of the ribs, or using double-locking stitching with rivets for reinforcement. This makes the connection between the canopy and ribs more secure and less likely to detach when subjected to chopping or pulling. The method used needs to be selected based on the user's requirements.

[0031] To enable the riot control umbrella 1 to have an active restraining capability, the bottom surface of the umbrella shaft of the riot control umbrella 1 is provided with a hollow handle 11 with one open end. The bottom surface of the umbrella shaft of the riot control umbrella 1 passes through the closed end of the hollow handle 11 and extends out, so that the umbrella shaft and the hollow handle 11 are fixedly connected. The advantage of this structure is that the umbrella shaft passes directly through the inside of the handle rather than just being inserted into the end of the handle, which significantly improves the connection strength between the handle and the umbrella shaft. The handle will not detach from the umbrella shaft when forcefully swung or during window breaking operations. In order to ensure the connection strength, screws passing through the umbrella shaft and the hollow handle 11 are generally used for reinforcement.

[0032] The hollow handle 11 has a detachable press-type tear gas bottle 2 inside its cavity. The tear gas bottle is stored inside the handle instead of being attached externally, which not only maintains the concealment and integrity of the umbrella's appearance, but also avoids the risk of accidental contact and leakage during carrying. The press-type tear gas bottle 2 is a tear gas bottle with a spring-loaded reset structure. When the outlet is pressed, tear gas spray is emitted. After the outlet is released, it automatically resets and closes under the action of the spring.

[0033] The open end of the hollow handle 11 is provided with an internally threaded sealing cap 12, which is threadedly engaged with the open end of the hollow handle 11 to seal the open end of the hollow handle 11. This threaded connection structure makes it convenient for users to regularly inspect or replace the press-type tear gas bottle 2 (when replacement is needed, simply unscrew the internally threaded sealing cap 12, take out the old bottle and put in the new bottle, and then tighten the internally threaded sealing cap 12. The operation is simple and quick).

[0034] like Figures 2 to 6 As shown, a push-button switch 3 is provided on one side of the outer wall of the hollow handle 11 to control the start and stop of the push-button tear gas bottle 2. The push-button switch 3 includes a sliding slider 31, a pressing block 32 and a limiting groove 33. The sliding slider 31 is sleeved on the output port of the push-button tear gas bottle 2. When the sliding slider 31 slides axially, its inner wall can press the output port of the tear gas bottle to trigger the spray.

[0035] The translation slider 31 has several inclined slopes to convert the vertical movement of the pressing block 32 into the axial movement of the translation slider 31. The translation slider 31 has a slider channel 311 inside for transmitting the spray output from the press-type tear gas bottle 2. The output end of the slider channel 311 is a tapered pipe. The tapered design facilitates the sealed insertion with a hose. The input end of the slider channel 311 is opposite to the inclined end of the translation slider 31.

[0036] The pressing block 32 passes through the side wall of the hollow handle 11, and its inner end corresponds to the inclined surface of the translation slider 31. The top surface of the pressing block 32 is provided with anti-slip texture to increase the friction when the finger presses and prevent slipping; the bottom surface of the pressing block 32 is provided with an inclined groove corresponding to the inclined surface of the translation slider 31. When the pressing block 32 is pressed down, the inclined groove and the inclined surface interact to smoothly convert the vertical movement of the pressing block 32 into the axial movement of the translation slider 31.

[0037] The hollow handle 11 has a limiting groove 33 inside. The limiting groove 33 is cross-shaped and is used to limit the sliding slider 31 to slide only along the axial direction of the hollow handle 11, so as to prevent it from deflecting or misaligning during the pressure process. The two side walls of the sliding slider 31 are provided with ear plates 331 corresponding to the limiting groove 33. The ear plates 331 are embedded in the limiting groove 33 and the two slide together to ensure that the sliding slider 31 slides smoothly in the predetermined direction. (In order to ensure the verticality of the hollow handle 11 when it moves up and down, multiple pin connection structures are generally designed on the bottom surface of the limiting groove 33 or the bottom surface of the hollow handle 11.)

[0038] The working principle of the push-button switch 3 is as follows: When the user presses the push-button block 32, the push-button block 32 moves vertically towards the bottom surface of the limiting groove 33. The inclined groove at its bottom pushes the inclined slope of the translation slider 31, causing the translation slider 31 to slide along the axial direction of the hollow handle 11. During the sliding process, the inner wall of the translation slider 31 presses the output port of the push-button tear gas bottle 2, causing the tear gas bottle to spray tear gas spray. The spray is output through the slider channel 311 inside the translation slider 31. When the user releases the push-button block 32, the output port of the push-button tear gas bottle 2 automatically resets and closes under the action of the spring, and at the same time pushes the translation slider 31 to reset. The push-button block 32 also resets to the initial position synchronously under the cooperation of the inclined surface. The whole process can be completed with one hand. Moreover, the push-button block 32 is set on the side wall of the handle, which is ergonomic. The user can naturally complete the pressing action while holding the umbrella.

[0039] like Figure 3 , Figure 7 , Figure 8 and Figure 9 As shown, the top surface of the riot control umbrella body 1 is provided with a window-breaking cone 5, and the inside of the window-breaking cone 5 is provided with a nozzle 51. The output end of the slider channel 311 is connected to the input end of the nozzle 51 through a flexible hose. The flexible hose is located inside the umbrella pole of the riot control umbrella body 1, extending from the hollow handle 11 at the bottom of the umbrella pole to the window-breaking cone 5 at the top of the umbrella pole. It makes full use of the hollow space inside the umbrella pole as a transmission channel. The advantage of this wiring method is that the flexible hose is not exposed throughout, which protects the flexible hose from external wear and ultraviolet aging, maintains the neat and beautiful appearance of the umbrella body, and also prevents the flexible hose from being pinched or tangled during folding or unfolding.

[0040] The window-breaking cone 5 is connected to the upper nest via an L-shaped groove locking connection structure 4. The L-shaped groove locking connection structure 4 includes an L-shaped groove 41 and a locking block 42. The L-shaped groove 41 is located on the side wall of the inner hole on the top surface of the upper nest of the riot umbrella body 1, and the locking block 42 is located on the side wall of the insertion end of the window-breaking cone 5. The locking block 42 and the L-shaped groove 41 are positioned correspondingly. During installation, the insertion end of the window-breaking cone 5 is inserted into the inner hole on the top surface of the upper nest, so that the locking block 42 is aligned with the L-shaped groove 41. The vertical inlet end of the L-shaped groove 41 is then rotated, and the window-breaking cone 5 is rotated so that the locking block 42 slides along the L-shaped groove 41 to the locking position, thereby achieving a quick locking connection between the window-breaking cone 5 and the upper cavity. When disassembly is required, the window-breaking cone 5 is rotated in the opposite direction so that the locking block 42 is removed from the L-shaped groove 41, and the window-breaking cone 5 can be pulled out. In order to ensure the stability of the L-shaped groove 41 and the locking block 42 after connection, sealant is applied to the splicing surface during splicing.

[0041] The advantages of this L-shaped groove locking connection structure 4 are: it enables the detachable and quick installation of the window-breaking cone 5, allowing users to flexibly install and remove it according to actual needs. It can be quickly installed when needed to break the window and removed when not needed to reduce the weight of the umbrella top or avoid accidental injury. At the same time, the L-shaped groove 41 and the locking block 42 have good self-locking performance and will not automatically loosen during window-breaking impact.

[0042] Nozzle 51 is used to spray tear gas spray outwards from the top of the umbrella. The input end of nozzle 51 is located on the bottom surface of the insertion end of the window breaker cone 5, and the input end of nozzle 51 is a tapered insertion pipe. Before the window breaker cone 5 is inserted into the upper nest through the L-shaped groove locking connection structure 4, the tapered pipe of the input end of nozzle 51 is connected to the output end of the hose extending from the top of the umbrella pole. The tapered structure ensures automatic centering and sealing during the insertion process, and an airtight connection can be formed without additional operation, ensuring that the tear gas spray is smoothly delivered from the hose to the nozzle 51 and sprayed outwards. After the hose connection is completed, the window breaker cone 5 is inserted into the upper nest (the hose length is slightly longer than the distance between the output end of the slider channel 311 and the input end of nozzle 51).

[0043] The tip of the window breaker cone 5 is a conical metal head with high hardness, which can effectively shatter targets such as car windows when breaking windows is needed. Users can quickly break windows by striking the target glass with the tip of the window breaker cone 5 while holding the riot umbrella. During the window breaking process, the umbrella surface forms a natural shield in front of the user, blocking the flying glass fragments and reducing the user's risk of being cut, significantly improving the safety of the window breaking operation. In addition, the window breaker cone 5 also protects the umbrella ribs and the upper nest connector on the top surface. When a knife or axe is used to strike from above, the conical metal head can absorb the impact first, preventing the connection structure of the umbrella ribs and the upper nest from being directly damaged.

[0044] The complete method of using the multi-functional riot control umbrella of this invention is as follows:

[0045] In its everyday carrying configuration, the umbrella ribs can be folded and stowed, significantly shortening the length of the umbrella to fit into a police officer's tactical belt or personal bag, making it easy to carry without hindering normal operations.

[0046] When in rain or sun protection mode, unfold the umbrella ribs, and the canopy will tighten to form a shield, thus performing the normal rain and sun protection functions of a regular umbrella.

[0047] When the tear gas is in spray mode, the user holds the hollow handle 11, pointing the umbrella towards the direction of the threat as a protective barrier. Then, the user presses the pressure block 32 on the side of the hollow handle 11. The tear gas spray is delivered through a hose inside the umbrella shaft to the nozzle 51 at the top of the umbrella, spraying towards the direction of the threat. Because the umbrella forms a shield in front of the user, the influence of wind direction on the effectiveness of the tear gas spray is reduced, ensuring that the spray accurately targets the area. Releasing the pressure block 32 stops the spraying.

[0048] With the window broken, install the window-breaking cone 5 onto the top surface of the upper nest through the L-shaped groove locking connection structure 4, and use the tip of the cone to strike the target glass while holding the riot umbrella to quickly break the window.

[0049] When replacing tear gas canisters, unscrew the internal threaded cap 12 at the open end of the hollow handle 11, remove the old press-type tear gas canister 2, insert the new press-type tear gas canister 2, and then tighten the internal threaded cap 12.

[0050] As a preferred embodiment, the multifunctional riot control umbrella of the present invention has an unfolded diameter of 80cm, an unfolded length of 55cm, a total weight of approximately 600g, and a folded length of 31cm. The umbrella surface is made of cut-resistant fabric coated with a PU film, which has both knife and axe protection and rain protection functions. It should be noted that the above parameters are only preferred examples, and those skilled in the art can make adjustments according to actual needs without departing from the concept of the present invention. These adjustments are still within the protection scope of the present invention.

[0051] Based on the above embodiments, those skilled in the art can also make the following modifications:

[0052] Regarding the type of tear gas bottle, the tear gas agent inside the press-type tear gas bottle 2 can be OC capsaicin tear gas, CS tear gas, or other irritant sprays with repellent or subduing effects.

[0053] Regarding the number of locking connection structures, the number of L-shaped grooves 41 and locking blocks 42 in the L-shaped groove locking connection structure 4 can be one or more, for example, 2 to 3 sets of circumferentially distributed L-shaped grooves and locking blocks can be set to further improve the connection strength and stability.

[0054] Regarding the material of the hose, the hose can be a silicone hose, a rubber hose, or other tubing with good flexibility and chemical corrosion resistance.

[0055] Regarding the folding method of the umbrella ribs, the folding method is not limited to two folds. Three folds or other multi-section folding methods can also be used, as long as they can achieve the purpose of being easy to carry after folding.

[0056] Regarding the placement of the push-button switch, the push-button block 32 of the push-button switch 3 can be placed on the left or right side of the hollow grip 11 to accommodate the hand habits of different users.

[0057] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
