Description

Technical Field

[0001] This invention relates to tempered glass breakers, and more specifically, to flat tempered glass breakers for breaking tempered glass in emergency situations such as those involving automobiles or buildings. Background Technology

[0002] Serious casualties can occur when a vehicle catches fire and cannot be evacuated from the vehicle, such as in cases of collisions, rear-end collisions, rollovers, overturning accidents, head-on collisions, falling accidents, or flooding accidents on highways or general roads.

[0003] In particular, not only in South Korea but also worldwide, the number of property damage and casualties caused by bus fires is on the rise, and the government has issued more than 1,000 emergency exit and fire extinguisher-related rectification notices in the past five years. However, despite these government measures, the number of accidents continues to surge every year.

[0004] In these accidents, most deaths were caused by asphyxiation. During a fire, smoke makes it difficult to ensure visibility, thus delaying escape. Moreover, in most cases, inhaling just one cloud of smoke can cause asphyxiation due to narrowed airways.

[0005] Besides fires, when a car falls into water, the water entering the car creates a pressure difference between the inside and outside, making it difficult to open the doors and causing a long time to escape from the vehicle, thus drastically reducing the survival rate.

[0006] Most car windows are made of tempered glass, which is 4 to 5 times stronger than ordinary glass. Because it undergoes a high-heat treatment, it is not easily broken. Recently, double-glazed windows, increasingly used to ensure quiet interior spaces, are even more difficult to break.

[0007] The most commonly used escape safety device on buses is the safety hammer. However, in emergencies, rescuers must manually locate the hammer to break the windows, resulting in a very low usage rate. Furthermore, many safety hammers are simply strapped into the bus to prevent theft or are lost, rendering them unusable in practical situations. For example, in the event of a bus fire, the smoke makes it difficult to find the hammer. Even if found, it's difficult to quickly break the tempered glass windows, delaying escape time. Reports frequently indicate that this delay leads to more casualties. In particular, unlike in other countries, buses on highways in South Korea without central doors pose a greater challenge to escape during fires. Even with the increasing popularity of electric vehicles, battery discharge often prevents the doors from opening, leading to deaths from fires on board. Cases of passengers being unable to open their electric vehicles in rooftop parking lots during the summer and needing assistance from passing citizens are also frequent.

[0008] Accordingly, cars have recently been equipped with glass breakers that can easily shatter tempered glass in place of safety hammers.

[0009] Recently, Korean Patent Publication No. 10-2020-0144433, entitled "Glass Breaking Device," disclosed a glass breaking device for automobiles. As disclosed in this patent, existing glass breaking devices have a rigid breaking part located inside a housing under the compression of a spring. If the user releases the fixing force of the spring, the breaking part breaks the tempered glass by working through the elastic force of the spring.

[0010] However, existing glass breaking devices that utilize the elasticity of compression springs frequently malfunction due to spring failure. Furthermore, the compression springs need to be housed internally, resulting in a long, narrow shape that can be aesthetically unpleasing or restrict passage when attached to windows. Moreover, the spring quality cannot be maintained uniformly depending on the spring's quality, frequency of use, and storage environment. Therefore, these devices are flawed as they should always be in optimal condition.

[0011] In addition, most glass breakers sold on the market use low-cost plastic or heat-treated metal products for their breaking tips, which can only break glass by striking specific parts such as corners, thus reducing their effectiveness. Manufacturers of these products generally do not use high-hardness breaking tips that can easily break glass as materials due to cost reduction and low marketability. Summary of the Invention

[0012] (The problem to be solved)

[0013] The purpose of this invention is to solve the above-mentioned problems by providing a tempered glass breaker that is made into a low-profile flat plate shape, so that it can be attached to the glass window without protruding.

[0014] Another object of the present invention is to provide a tempered glass breaker that does not use elastic components and can therefore be used without failure.

[0015] Those skilled in the art will become more aware of the above-mentioned objects and various advantages of the present invention from the preferred embodiments thereof.

[0016] (Solutions)

[0017] The aforementioned objective of the present invention can be achieved through a flat tempered glass breaker. The tempered glass breaker of the present invention includes: a support portion configured to contact a predetermined area with the surface of the tempered glass to be broken, and having a tip movement hole formed on its surface; an impact portion vertically coupled to the upper part of the support portion, and having a breaking tip disposed in a central region, the breaking tip striking the tempered glass through the tip movement hole as it descends; and a safety pin inserted between the support portion and the impact portion to prevent arbitrary descent of the impact portion. The support portion includes: a support plate forming the tip movement hole and disposed on the surface of the tempered glass to be broken; a breaking tip guide tube vertically formed at the outer periphery of the tip movement hole to guide the descent of the breaking tip; and a lower outer guide tube disposed outside the breaking tip guide tube and arranged concentrically with the breaking tip guide tube. The striking part includes: an upper housing that is pressurized for descent; a tip fixing shaft that is vertically formed downward in the central region of the upper housing to house the breaking tip, exposing the lower end of the breaking tip in the lower part, and descending along the breaking tip guide tube; and an upper outer guide tube that is arranged in a concentric circle shape on the outer periphery of the tip fixing shaft so as to descend with the lower outer guide tube to ground externally when the striking part descends.

[0018] According to one embodiment, the lower external guide tube may include: a plurality of guide plates arranged in an arc shape at predetermined intervals; a plurality of shape holding plates disposed between adjacent guide plates and forming a height higher than the guide plates, and detachably coupled from the support plate when the striking part descends.

[0019] According to one embodiment, the safety needle includes: a safety needle body; an outer tube insertion ring disposed inside the safety needle body and formed corresponding to the outer diameter of the lower outer guide tube for elastic engagement with the lower outer guide tube; and a handle disposed at the rear of the safety needle body. A pressure neck is formed at the front end of the outer tube insertion ring, forming a straight line of a predetermined length with respect to the insertion direction of the lower outer guide tube, for elastic contact and pressure on the outer wall of the lower outer guide tube; and an outer curved end, formed by bending outward from the end of the pressure neck; wherein an elastic gap space can be formed between the outer curved end and the side wall of the safety needle body, and the elastic gap space can elastically deform when the outer tube insertion ring is attached to or detached from the lower outer guide tube.

[0020] According to one embodiment, a lower hook and an upper hook may be configured at the upper end of the crushing tip guide tube and the lower end of the tip fixing shaft. The lower hook and the upper hook form corresponding shapes to engage with each other to guide the descent of the tip fixing shaft.

[0021] According to one embodiment, the tempered glass breaker may further include a marking portion detachably attached to the top of the upper housing.

[0022] (The effect of the invention)

[0023] The tempered glass breaker of the present invention does not use an additional elastic component, but rather applies an impact to break the tempered glass as the breaking tip descends. Because it does not use an additional elastic component, it has a flat structure, unlike the elongated shape of conventional cones.

[0024] Therefore, even if attached to windows or other surfaces, it does not affect the appearance and has the advantage of being able to be stored neatly.

[0025] In addition, since no elastic components are used, the problem of malfunctions caused by failure of elastic components can be solved.

[0026] In addition, the use of a breaking tip with a hardness such as tungsten carbide ensures the shortest possible distance for impact, even with a flat structure, thus providing a stable effect in breaking tempered glass.

[0027] In addition, the shape retention plate of the tempered glass breaker breaks or bends after one use, so managers can easily confirm whether it has been used or not with the naked eye, thus having the advantage of maintaining its optimal condition. Attached Figure Description

[0054] A: Tempered glass Detailed Implementation

[0055] To fully understand the present invention, preferred embodiments are described with reference to the accompanying drawings. Embodiments of the present invention can be formed into various shapes, and the scope of the invention is not limited to the embodiments described in the following detailed description. These embodiments are provided to provide a more complete explanation of the invention to those skilled in the art. Therefore, to emphasize clarity, the shapes of components in the drawings may be exaggerated. Note that identical parts in various drawings may be labeled with the same reference numerals. Detailed descriptions of well-known functions and structures deemed to obscure the focus of the invention are omitted.

[0056] Figure 1 and Figure 2 These are perspective views showing the tempered glass breaker 100 of the present invention in conjunction with the handle 145 at different angles. Figure 3 and Figure 4 This is an exploded perspective view showing the structure of the tempered glass breaker 100 of the present invention at different angles.

[0057] As shown in the figure, the tempered glass breaker 100 of the present invention includes: a support portion 110 disposed on the surface of the tempered glass to be broken; a striking portion 120 disposed on the upper part of the support portion 110 and capable of moving up and down to strike and break the tempered glass; a safety pin 140 inserted between the striking portion 120 and the support portion 110 to prevent the striking portion 120 from descending under normal conditions; and a marking portion 130 attached to the upper part of the striking portion 120.

[0058] The tempered glass breaker 100 of the present invention is formed such that the support portion 110 and the striking portion 120 are arranged side by side in a flat plate shape with a predetermined area, thereby having an overall flat shape. Accordingly, it will not protrude outward even when attached to a glass window of a bus or the like, thus having the advantage of not affecting the appearance.

[0059] Furthermore, since no additional elastic component is required, the striking part 120 breaks the tempered glass by striking it with pressure applied by personnel after the safety pin 140 is removed. Therefore, there is no concern about the failure of the elastic component, and it has the advantage of being able to perform reliable work.

[0060] The support portion 110 contacts the surface of the tempered glass to be broken and supports the striking portion 120, so that the striking portion 120 descends steadily to strike the tempered glass to apply an impact. Figure 3 and Figure 4 As shown, the support portion 110 includes: a support plate 111, which forms a tip moving hole 111a through the central region; a crushing tip guide tube 113, which forms a predetermined height vertically upward to surround the tip moving hole 111a; and a lower outer guide tube 112, which forms a predetermined height and forms a concentric circle shape with the crushing tip guide tube 113.

[0061] The support plate 111 is configured as a plate shape with a predetermined area, and applies a supporting force to the surface of the tempered glass so that the striking part 120 can be lowered to apply an impact. In addition to the triangular shape shown in the figure, the support plate 111 can also be configured as various polygonal shapes or disk shapes.

[0062] A tip movement hole 111a is formed through the central region of the support plate 111 so that the striking part 120 and the breaking tip 123 can descend and contact the tempered glass.

[0063] The crushing tip guide tube 113 is formed vertically at a predetermined height along the inner wall surface of the tip moving hole 111a to guide the crushing tip 123 into the tip moving hole 111a when the striking part 120 descends. A plurality of lower hooks 113a are formed at predetermined angular intervals along the circumferential direction at the upper end of the crushing tip guide tube 113, and reinforcing ribs 113b supporting the lower hooks 113a are disposed on the outer wall surface of the crushing tip guide tube 113 where the lower hooks 113a are formed.

[0064] Figure 7 This is a cross-sectional view showing the state of the striking section 120 before it is raised and strikes; Figure 8 This is a cross-sectional example diagram showing the state in which the striking part 120 descends to strike the tempered glass A.

[0065] like Figure 7 and Figure 8 As shown, the crushing tip guide tube 113 surrounds the tip fixing shaft 122 to guide the tip fixing shaft 122 to move toward the tip moving hole 111a, wherein the tip fixing shaft 122 surrounds the crushing tip 123 of the striking part 120.

[0066] The crushing tip guide tube 113 is formed to have an outer diameter larger than that of the tip fixing shaft 122. At this time, the lower hook 113a matches and engages with the upper hook 122c formed on the tip fixing shaft 122 to prevent the striking part 120 from detaching from the support part 110.

[0067] like Figure 7 As shown in the enlarged portion, the lower hook 113a is not formed at an angle perpendicular to the ground, but rather with a first acute angle θ1 inclined downwards, while the upper hook 122c is formed with a second acute angle θ2 inclined upwards from the direction opposite to the first acute angle. Accordingly, the lower part of the lower hook 113a and the upper part of the upper hook 122c are joined together at an angle that is offset from each other, so that if the upper hook 122c wants to detach from the outside of the crushing tip guide tube 113, it will be physically stuck by the lower hook 113a.

[0068] With this structure, the crushing tip guide tube 113 receives force in the direction toward the tip fixing shaft 122, while the tip fixing shaft 122 receives force toward the crushing tip guide tube 113, thus creating the effect that the crushing tip guide tube 113 and the tip fixing shaft 122 are aligned in a direction that approaches each other.

[0069] Accordingly, the tip fixing shaft 122 of the upper hook 122c is kept in a state where it is restricted by the broken tip guide tube 113.

[0070] The reinforcing ribs 113b formed on the back of each lower hook 113a reinforce the outer wall of the crushing tip guide tube 113 when the crushing tip 123 descends with the tip fixing shaft 122, so as to firmly hold and support the crushing tip guide tube 113 and prevent the crushing tip guide tube 113 from breaking due to the descending pressure of the crushing tip 123.

[0071] The lower outer guide tube 112 and the crushing tip guide tube 113 form a concentric circle shape, forming a predetermined height on the support plate 111, and the lower outer guide tube 112 has an outer diameter larger than that of the crushing tip guide tube 113. The lower outer guide tube 112 is formed by combining a plurality of guide plates 112a, 112b arranged at predetermined intervals and a plurality of shape-holding plates 115 arranged between adjacent guide plates 112a, 112b.

[0072] like Figure 8As shown, the lower outer guide tube 112 is formed such that its outer diameter corresponds to the inner diameter of the upper outer guide tube 125 formed on the striking part 120, so that when the striking part 120 descends, it moves while the inner wall surface of the upper outer guide tube 125 contacts the outer wall surface of the lower outer guide tube 112. Accordingly, the striking part 120 is such that the tip fixing shaft 122 moves along the breaking tip guide tube 113, while the upper outer guide tube 125 moves along the lower outer guide tube 112, thereby allowing the breaking tip 123 to strike the tempered glass surface connected to the tip moving hole 111a stably and accurately without wobbling.

[0073] A shape-holding plate 115 is disposed between adjacent guide plates 112a and 112b. If the user does not apply pressure to the striking part 120, the striking part 120 remains in a standby position, raised from the support plate 111. The shape-holding plate 115 is formed to be a predetermined height higher than the guide plates 112a and 112b. Then, a locking block 115a is disposed on the outer side of the upper end of the shape-holding plate 115, the locking block 115a protruding outwards by a predetermined height to lock the lower end of the upper external guide tube 125.

[0074] The upper end of the locking block 115a engages with the lower end 125a of the upper external guide tube 125, and a safety pin 140 is inserted between the support plate 111 and the locking block 115a. For example... Figure 3 As shown, the height d1 from the support plate 111 to the locking block 115a is set to correspond to the height d2 of the side wall 141a of the safety pin 140. Accordingly, as Figure 5 As shown, if the safety pin 140 is inserted between the support plate 111 and the striking part 120, then the safety pin 140 is inserted between the support plate 111 and the locking block 115a.

[0075] Then, as Figure 7 As shown, in the standby position, the lower end 125a of the upper external guide tube 125 is locked in the locking block 115a, thereby keeping the striking part 120 in an upward position and preventing it from descending to the support part 110.

[0076] On the other hand, if the striking part 120 is applied by personnel, the locking block 115a breaks at the shape-holding plate 115. The shape-holding plate 115 cannot be vertically fixed to the support plate 111, but instead bends towards the breakage tip guide tube 113, thereby causing the striking part 120 to descend. Therefore, as... Figure 4 As shown, a cutting groove 116 is formed at the junction of the lower end of the shape retaining plate 115 and the support plate 111. The lower end of the shape retaining plate 115 is joined to the support plate 111 with a shallow thickness, and a cutting groove 116 of a predetermined width is formed behind it. Accordingly, if pressure is applied to the shape retaining plate 115 from above, the shape retaining plate 115 will break or bend in the direction outward from which the cutting groove 116 is formed.

[0077] If the locking block 115a breaks, the locking block 115a that is blocking the upper external guide tube 125 will be removed, therefore... Figure 8 The striking part 120 shown descends toward the support plate 111.

[0078] If the user sees that the locking block 115a is broken or bent, they can confirm whether the tempered glass breaker 100 is in use.

[0079] The striking part 120 descends from the upper part to the lower part of the support part 110 to strike the tempered glass A, thereby breaking the tempered glass A. Figure 3 and Figure 4 As shown, the striking part 120 includes: an upper housing 121; a tip fixing shaft 122 formed in the central region of the upper housing 121 facing downward; a breaking tip 123 that houses the tip fixing shaft 122 and strikes the tempered glass A to break the tempered glass A; and an upper external guide tube 125 that is arranged in a concentric circle shape on the outer periphery of the tip fixing shaft 122 and descends along the lower external guide tube 112.

[0080] The upper outer casing 121 fixes the crushing tip 123, which can be lowered by manual pressure. The upper outer casing 121 is formed into a flat plate shape corresponding to the support plate 111, and is formed into a flat outer casing shape with a predetermined height on the sides, thereby shielding the tip fixing shaft 122 housed inside.

[0081] Multiple leg slots 121a are formed on the surface of the upper outer casing 121, and the leg slots 121a engage with the connecting legs 133 of the display panel 131. The connecting legs 133 formed on the lower part of the display panel 131 are inserted into the leg slots 121a, and the hooks 133a formed on the lower part of the connecting legs 133 are engaged.

[0082] like Figure 1 As shown, a stop insertion groove 121b is cut into the lower part of the upper outer shell 121. When the safety pin 140 is attached to the support part 110, the upper stop 147 of the safety pin 140 can be inserted into the stop insertion groove 121b.

[0083] A tip fixing shaft 122 is formed vertically downwards on the upper inner wall surface of the upper housing 121 to support the breaking tip 123. For example... Figure 4 and Figure 7 As shown, the tip fixing shaft 122 exposes the breaking tip 123 only to the lower part. That is, the tip fixing shaft 122 minimizes the contact area of ​​the breaking tip 123 that contacts the tempered glass A in order to maximize the impact efficiency during impact.

[0084] like Figure 7As shown, a tip insertion hole 122a is formed inside the tip fixing shaft 122. The tip support shaft 123a of the crushing tip 123 is inserted into the tip insertion hole 122a. The coupling expansion end 123b formed at the upper end of the tip support shaft 123a engages in the tip insertion hole 122a, thereby fixing the position of the crushing tip 123 in the tip support shaft 123a.

[0085] Multiple upper hooks 122c are arranged circumferentially at the lower end of the tip-fixed shaft 122. For example... Figure 7 As shown, the lower hook 113a protrudes outward in the radial direction and matches and engages with the upper hook 122c of the tip fixing shaft 122 to prevent the breaking tip 123 from dislodging and to allow the striking part 120 to descend stably.

[0086] At this time, a lower hook guide groove 122b is formed on the outer peripheral surface of the tip fixing shaft 122, which is recessed relative to the plate surface, to guide the movement of the lower hook 113a that matches and engages with the upper hook 122c when the striking part 120 descends. Accordingly, when the striking part 120 descends, the multiple lower hooks 113a move along the corresponding lower hook guide grooves 122b, allowing the striking part 120 to descend to its original position without shaking.

[0087] like Figure 8 As shown, the breaking tip 123 is exposed at the lower end of the tip fixing shaft 122, and when the striking part 120 descends, it contacts the tempered glass A to apply an impact, thereby breaking the tempered glass A.

[0088] The breaking tip 123 can be formed of a material with high hardness, thus enabling it to exert a large impact even with a small size when in contact with tempered glass A. For this purpose, the breaking tip 123 is formed of tungsten carbide or a material with a hardness comparable to tungsten carbide.

[0089] The breaking tip 123 is formed into an inverted triangle shape at the lower end of the tip support shaft 123a, which minimizes the part in contact with the tempered glass A and thus maximizes the impact during impact.

[0090] The upper external guide tube 125 forms a concentric circle shape on the outer periphery of the tip fixing shaft 122, so that when the striking part 120 descends, it moves along the lower external guide tube 112 to guide the striking part 120 to descend stably.

[0091] like Figure 8 As shown, the upper external guide tube 125 is formed to have an inner diameter corresponding to the outer diameter of the lower external guide tube 112. When the striking part 120 descends, it moves along the outer wall surface of the lower external guide tube 112, so that the striking part 120 descends stably without shaking.

[0092] Here, the upper outer shell 121, the tip fixing shaft 122, and the upper external guide tube 125 of the striking part 120 are manufactured as a whole by injection molding, and the crushing tip 123 is fixed at the position of the tip fixing shaft 122 by embedded insertion.

[0093] The marking section 130 is provided on top of the striking section 120 to enhance the strength of the striking section 120 and to indicate to the user that in an emergency, the tempered glass breaker 100 can be used to break the tempered glass A before escaping.

[0094] The signage 130 includes: a display panel 131 attached to the upper housing 121; and a plurality of mounting legs 133 protruding downward in the border area of ​​the display panel 131 to attach to the upper housing 121. The display panel 131 is configured as a flat plate shape corresponding to the upper surface of the upper housing 121 and is attached to the upper housing 121 to enhance the strength of the upper housing 121.

[0095] Additionally, although not shown, text indicating the use of the tempered glass breaker in emergency situations may be printed directly on the surface of the display panel 131, or printed paper may be affixed to show the user the purpose and method of use of the tempered glass breaker 100. Furthermore, design elements such as logos may be affixed to the display panel 131.

[0096] like Figure 4 As shown, an anti-deformation groove 135 is disposed along the outer periphery of the lower part of the display panel 131. The anti-deformation groove 135 corresponds to the property that the marking part 130 can be deformed due to the characteristics of the corrugated molded material during injection molding, thus preventing the marking part 130 from deforming.

[0097] The safety pin 140 is attached between the support portion 110 and the striking portion 120 to prevent the striking portion 120 from arbitrarily descending in non-emergency situations. Normally, the safety pin 140 is inserted between the support portion 110 and the striking portion 120 to prevent the striking portion 120 from descending. In an emergency, personnel can remove the safety pin 140 to allow the striking portion 120 to descend.

[0098] like Figure 3 and Figure 4 As shown, the safety needle 140 includes: a vertical plate-shaped safety needle body 141; an outer tube insertion ring 143, which is attached to the inner side of the safety needle body 141 and detachably attached to the lower outer guide tube 112 of the support portion 110; and a handle 145, which is disposed at the rear of the safety needle body 141 and allows the user to grip the safety needle 140.

[0099] The safety pin body 141, handle 145, and outer tube insertion ring 143 are integrally formed by injection molding. The safety pin body 141 is configured to surround the entire exterior of the upper housing 121 together with the handle 145.

[0100] A sidewall 141a is disposed on the outside of the safety needle body 141, connecting the sidewall 141a to the handle 145, and an outer tube insertion ring 143 is formed between the sidewall 141a and the inside of the safety needle body 141. Figure 5 As shown, the outer tube insertion ring 143 is formed into a front-open ring shape for insertion into the lower outer guide tube 112.

[0101] Here, as Figure 3 As shown, the height d2 of the side wall 141a of the safety pin body 141 is configured to correspond to the height d1 between the support plate 111 and the locking block 115a of the shape retention plate 115, thereby inserting the safety pin 140 between the support plate 111 and the locking block 115a.

[0102] The outer tube insertion ring 143 is formed to have an outer diameter corresponding to the outer diameter of the lower outer guide tube 112 and is elastically open to accommodate the lower outer guide tube 112 inside.

[0103] A pressure neck 143a is formed at the end of the outer tube insertion ring 143. The pressure neck 143a is configured to be a straight line of a predetermined length facing forward to contact and pressurize the outer wall surface of the lower outer guide tube 112. Then, an outer curved end 143b is formed at the end of the pressure neck 143a. The outer curved end 143b is bent toward the side wall 141a to support the pressure neck 143a to elastically open or close.

[0104] Here, an elastic gap space 144 of a first width W1 is provided between the outer curved end 143b and the side wall 141a. The elastic gap space 144 forms extra space so that the pressure neck 143a can open or close when the safety pin 140 is inserted into or separated from the lower outer guide tube 112.

[0105] Accordingly, Figure 5 As shown, if the external tube insertion ring 143 is inserted into the lower external guide tube 112, the pressure neck 143a opens, and the second width W2 of the elastic interval space 144 is smaller than the first width W1.

[0106] Without the elastic space 144, when the external curved end 143b is fixed in the side wall 141a, the side wall 141a creates resistance to the elastic deformation of the pressure neck 143a, so the user cannot easily attach or detach the safety pin 140.

[0107] like Figure 1 As shown, the handle 145 is positioned behind the safety pin body 141 and protrudes outward when the safety pin 140 is engaged between the support portion 110 and the striking portion 120. Accordingly, the user can separate the safety pin 140 by grasping the handle 145 and pulling it backward.

[0108] On the other hand, an upper stop 147 and a lower stop 148 are respectively disposed at the upper and lower ends of the central region of the safety pin body 141. The upper stop 147 and the lower stop 148 limit the insertion depth of the safety pin 140 into the space between the support portion 110 and the striking portion 120, and at the same time suppress the rotation of the safety pin body 141 during engagement with the support portion 110.

[0109] Reference Figures 1 to 8 The process of using the tempered glass breaker 100 of the present invention, which has this structure, is explained.

[0110] The tempered glass breaker 100 of the present invention is attached to and stored on the glass windows of buses, automobiles, buildings, etc. Specifically, double-sided adhesive tape is applied to the bottom surface of the support portion 110, and the tempered glass breaker 100 is attached to the surface of the glass window to be broken in an emergency for storage. Figure 1 and Figure 2 As shown, the tempered glass breaker 100 is stored with the safety pin 140 engaged in its normal storage condition.

[0111] like Figure 5 As shown, when the safety pin 140 is inserted into the lower outer guide tube 112 of the support portion 110 by the outer tube insertion ring 143 of the safety pin 140, the safety pin 140 is located between the support portion 110 and the striking portion 120, preventing the striking portion 120 from descending arbitrarily.

[0112] like Figure 6 As shown, in the event of a safety accident, the user pulls the handle 145 backward, thereby separating the safety pin 140 from the support part 110 and the striking part 120.

[0113] like Figure 6 and Figure 7 As shown, even if the safety pin 140 is removed, the lower end 125a of the upper external guide tube 125 is stuck in the locking block 115a of the shape holding plate 115, so the striking part 120 does not descend to the holding position.

[0114] The user applies downward pressure to the top of the upper housing 121. The pressure applied to the upper housing 121 causes the shape-holding plate 115 to bend, and the locking block 115a to break. The tip-fixing shaft 122 descends along the inside of the breaking tip guide tube 113.

[0115] At this time, the upper hook 122c moves along the inner wall of the crushing tip guide tube 113, while the lower hook 113a moves along the lower hook guide groove 122b, thereby guiding the striking part 120 to move vertically.

[0116] In addition, the upper external guide tube 125 descends along the outer wall of the lower external guide tube 112, so that the striking part 120 descends stably without shaking.

[0117] As the striking part 120 descends, the breaking tip 123 strikes the desired location of the tempered glass A through the tip moving hole 111a, thereby shattering the tempered glass A.

[0118] As described above, the tempered glass breaker of the present invention does not use additional elastic components; instead, the breaking tip descends to apply impact and break the tempered glass. Because no additional elastic components are used, it has a flat structure, rather than the elongated shape of a conventional cone.

[0119] Therefore, the tempered glass breaker is not attached to windows or other surfaces, and will not affect the appearance, thus having the advantage of being able to be stored neatly.

[0120] In addition, the tempered glass breaker does not use elastic components, thus solving the problem of malfunctions caused by failure of elastic components in the past.

[0121] In addition, the tempered glass breaker uses a breaking tip with a hardness such as tungsten carbide, which, even with its flat structure, ensures the shortest possible distance for impact, thus providing a stable effect in breaking tempered glass.

[0122] In addition, the tempered glass breaker retains its shape even after one use, so managers can easily visually confirm whether it has been used or not, thus maintaining its optimal condition.

[0123] The embodiments of the tempered glass breaker of the present invention described above are merely exemplary, and those skilled in the art to which this invention pertains will know that various modifications and equivalent embodiments can be achieved therefrom. Therefore, it is well understood that the invention is not limited to the shapes mentioned in the above detailed description. Consequently, the true scope of protection of the invention should be defined by the technical concept within the scope of the claims. Moreover, the invention should be understood to encompass the spirit of the invention as defined by the scope of the claims and all modifications, equivalents, and substitutions within that spirit.
