Description

Technical Field

[0001] This invention relates to emergency escape methods and devices for automobiles, such as those for selecting various escape methods that can be taken in an emergency when a car equipped with laminated glass is flooded or when passengers are trapped inside the car due to a traffic accident, so as to achieve a reasonable and reliable escape method and enable reliable and safe escape from the car. Background Technology

[0002] Recently, there has been an increase in cases where passengers have been trapped in submerged vehicles due to flooding caused by heavy rains or overflowing rivers.

[0003] In such a situation, passengers need to quickly cut their seat belts to release their restraints, break the door windows, and escape towards the outside of the vehicle.

[0004] As an emergency escape device that serves this purpose, the applicant has developed and proposed various devices.

[0005] For example, a fire extinguishing gas cylinder filled with carbon dioxide is filled into a breaking device. A seat belt guide groove is provided on the side of the breaking device, and a seat belt cutter is installed in the guide groove. The seat belt is guided into the seat belt guide groove and can be cut by the seat belt cutter. A hammer component is installed at the bottom of the filled fire extinguishing gas cylinder. The tip of the hammer component is struck against the door glass to break it. After escaping from the room, the head of the breaking device is operated to break the fire extinguishing gas cylinder and spray the fire extinguishing gas towards the fire source of the car to extinguish the fire (see Patent Document 1).

[0006] In addition, one end of the grippable cylindrical emergency escape device is equipped with a seat belt guide groove and a seat belt cutter, and a hammer is provided at the other end. The seat belt cutter is used to cut the seat belt inserted into the seat belt guide groove, and the tip of the hammer is used to strike the door glass to break it, thereby allowing escape towards the outside of the vehicle (see Patent Document 2).

[0007] However, recently, in order to improve sound insulation, cars have started using laminated glass in their door windows. This laminated glass consists of two single panes of glass and an interlayer made of synthetic resin bonded between them, possessing thin and strong properties.

[0008] In the event of an emergency in a car equipped with such laminated glass, the use of the escape device could result in the laminated glass being unbreakable, preventing passengers from escaping from the vehicle.

[0009] Therefore, as a technology to solve such problems, in a laminated glass for vehicles where an interlayer film is sandwiched between a pair of tempered glass panes, an impact area is provided in the interlayer film, and an impact-bearing component in the impact area, which is a cone-shaped or pyramidal shape made of metal, ceramic, etc., capable of breaking at least one of them, is provided. First, the impact area of ​​the tempered glass on the interior side is struck with a hammer or the like, so that the surface cracks reach the interior, and the cracks are destroyed by self-movement of the tempered glass as a whole.

[0010] The striking force of the hammer or the like is transmitted to the struck area, the intermediate film is compressed in the thickness direction, the sharp part of the struck component protrudes from the intermediate film and collides with the surface of another tempered glass, causing a crack to be generated on the surface of the tempered glass and reaching the interior of the glass. The crack moves on its own inside the glass and destroys the inner tempered glass, thus destroying a pair of tempered glass at the same time (see Patent Document 3).

[0011] However, the laminated glass for vehicles requires the formation of impact-bearing components and impact-bearing areas in the interlayer, which complicates their structure and manufacturing. In addition, this results in the laminated glass becoming more brittle, and there is a problem that the strength of the glass is actually reduced.

[0016] Patent Document 3: Japanese Patent Application Publication No. 2020-172404 Summary of the Invention

[0017] The technical problem that the invention aims to solve

[0018] The purpose of this invention is to solve the problem of providing an emergency escape method and device for automobiles, which, while maintaining the strength of the laminated glass, allows for the selection of various escape methods that can be taken in an emergency, such as when a car equipped with laminated glass is flooded or when passengers are trapped inside the car due to a traffic accident, in order to achieve a reasonable and reliable escape method that enables reliable and safe escape from the car.

[0019] Solutions for solving technical problems

[0020] The invention of technical solution 1 is an emergency escape method for automobiles using laminated glass. The method involves perforating, cutting, breaking, melting, or vibrating a designated area of ​​the laminated glass. After one or more emergency operations, the separated part is pressed outwards according to the operation position, pushing the laminated glass outwards. An escape space is formed between the pushed-out position and the installation part of the laminated glass, allowing passengers to escape from this space. Various escape methods can be selected in an emergency, achieving a reasonable and reliable escape method. In cases where a car using laminated glass is flooded or passengers are trapped inside due to a traffic accident, passengers can escape reliably and safely.

[0021] In the invention of technical solution 2, perforation is performed by violently impacting multiple parts of the laminated glass with a breaking tool, which easily and reliably creates an escape space and enables passengers to escape.

[0022] In the invention of technical solution 3, cutting is performed by having a blade bite into multiple parts of the laminated glass and moving it by human or power, or by using power to rotate the saw chain. By cutting the laminated glass by human or power, an escape space is quickly created, making it easy for passengers to escape.

[0023] In the invention of technical solution 4, the breaking is achieved by repeatedly striking multiple parts of the laminated glass with a blunt object, using simple tools and objects to break the laminated glass, easily creating an escape space, and facilitating the escape of passengers.

[0024] In the invention of technical solution 5, the melting is performed by irradiating multiple parts of the laminated glass with laser or microwave lasing light or electromagnetic waves, which quickly cuts the laminated glass, quickly creates an escape space, and quickly enables passengers to escape.

[0025] In the invention of technical solution 6, the vibration is achieved by repeatedly applying pressurized fluid or elastic vibration, or by irradiating ultrasonic waves to a designated area of ​​the laminated glass, causing the laminated glass to vibrate repeatedly, so that the laminated glass can be statically detached and disassembled to form an escape space, thus enabling passengers to escape smoothly.

[0026] In the invention of technical solution 7, the emergency operation position of the laminated glass can be selected according to the passenger's physique, seating position, and carriage conditions. The lower, middle, or upper position of the laminated glass can be selected according to the passenger's physique, seating position, and carriage conditions to carry out emergency operations in a reasonable posture. When the strength of the operation position decreases, the separation position, such as the upper, lower, or middle position, is pressed outward to push the laminated glass outward, thereby easily forming an escape space.

[0027] In the invention of technical solution 8, the emergency operation positions of the laminated glass are configured as closely as possible, and the operation intervals are removed using tools or knives to reduce the strength of the emergency operation section and achieve the rapid formation of an escape space.

[0028] In the invention of technical solution 9, after the breaking tool is separated from the laminated glass, it is moved violently to collide with it, so that the breaking tool and the amount of separation violently collide with the laminated glass, thereby achieving reliable breaking.

[0029] In the invention of technical solution 10, the laminated glass is disposed on the front door side, which can release the surrounding local constraints, so that the laminated glass can be pushed out and the escape space can be formed reasonably and easily after emergency operations.

[0030] The invention of technical solution 11 is an emergency escape device for automobiles using laminated glass, wherein the emergency escape device includes: a seat belt cutter; and a structural part capable of perforating, cutting, breaking, melting, or vibrating a specified area of ​​the laminated glass. After one or more emergency operations, the device is configured to be able to press the separation position outward according to the operation position to push the laminated glass outward, and is configured to be able to form an escape space between the pushed-out position and the installation part of the laminated glass, and is configured to allow passengers to escape from the escape space via the seat belt cutter. The device cuts off the seat belt, releasing the passenger's body from restraint. It allows for the selection of various escape methods in an emergency, providing a reasonable and reliable escape method. It can perform various emergency operations on the laminated glass. After the emergency operation, it is designed to be able to press the separation position outward according to the operation position and push the laminated glass outward, allowing the passenger to escape from the escape space between the pushed-out position and the installation part of the laminated glass. In emergencies such as when a car with laminated glass is flooded or when passengers are trapped inside the car due to a traffic accident, it can enable passengers to escape reliably and safely.

[0031] The invention of technical solution 12 has a glass breaking device at the other end of the emergency escape device. The glass breaking device is configured to make the breaking tool violently hit multiple parts of the laminated glass to make holes, and is configured to easily and reliably push the laminated glass outward, so as to easily form an escape space and realize the escape of passengers.

[0032] In the invention of technical solution 13, the blade is designed to bite into multiple parts of the laminated glass and can be moved by human power or electric power, or can be moved by rotating the saw chain by electric power. The laminated glass is designed to be cut. By cutting the laminated glass by human power or electric power, an escape space can be quickly formed, and passengers can easily escape.

[0033] In the invention of technical solution 14, it is designed to be able to repeatedly strike multiple parts of the laminated glass with a blunt object, using simple tools and objects to break the laminated glass, and to be able to easily form an escape space and easily realize the escape of passengers.

[0034] In the invention of technical solution 15, it is designed that the laminated glass can be melted by irradiating multiple parts of the laminated glass with laser or microwave lasing light or electromagnetic waves, so as to quickly cut the laminated glass, quickly form an escape space and quickly realize the escape of passengers.

[0035] In the invention of technical solution 16, it is configured to repeatedly apply pressurized fluid or elastic vibration to a specified area of ​​the laminated glass, or to apply ultrasonic waves to cause the laminated glass to vibrate repeatedly, to allow the laminated glass to statically detach and be disassembled, and to be easily pushed outward to form an escape space for passengers to escape.

[0036] In the invention of technical solution 17, the emergency escape device has an impact piece that can collide with the laminated glass. The impact piece is designed to move at high speed through the elasticity of a spring, so as to reliably break the laminated glass.

[0037] In the invention of technical solution 18, a square shaft and a spring box are slidably housed inside the emergency escape device. The square shaft houses a plate holder equipped with a first spring and an impact plate, and the spring box houses a second spring. The impact plate moves at high speed due to the elasticity of the first and second springs, thereby reliably breaking the laminated glass.

[0038] The invention of technical solution 19 sets the sheet retainer and the spring box to be able to move close to each other, and solves the problem of the accumulation of elasticity of the first spring and the second spring housed therein with a simple structure.

[0039] In the invention of technical solution 20, when the plate retainer and the spring box move close together, it is designed to accumulate the elasticity of the first spring and the second spring, so as to achieve a reasonable structure and make the impact plate move at high speed.

[0040] In the invention of technical solution 21, a roughly L-shaped pin engagement groove is formed in the square shaft portion, and a roughly parallelogram-shaped pin switching groove is formed in the spring box. These grooves are configured to partially overlap, and a guide pin is inserted into the overlapping portion. The guide pin is always positioned in the curved portion of the pin engagement groove for connection, thereby achieving a reasonable connection between the square shaft portion and the spring box.

[0041] In the invention of technical solution 22, when the square shaft part and the spring box move close together, the guide pin is configured to move together. When the square shaft part and the spring box move at a constant speed, the guide pin is configured to move along the switching edge of the pin switching groove. The guide pin is configured to move from the bent part of the pin engaging groove. The accumulated elasticity of the first spring and the second spring enables the plate retainer to move at high speed.

[0042] In the invention of technical solution 23, when the guide pin moves from the bent portion of the pin engagement groove, the sheet retainer is configured to move toward the front end of the square shaft portion by the elasticity stored by the first spring and the second spring, and the front end of the sheet retainer is configured to protrude from the front end of the square shaft portion, thereby enabling reliable breaking of laminated glass.

[0043] In the invention of technical solution 24, an opening is provided in the glass push plate at the front end of the square shaft portion. The opening is designed to be always closed by a rubber protective sheet to prevent tiny fragments caused by the breakage of the laminated glass from entering the opening. This prevents internal malfunctions from occurring and allows the front end of the sheet holder to reliably protrude, enabling reliable breakage of the laminated glass.

[0044] In the invention of technical solution 25, a locking protrusion is provided at the opposite position of the rear end of the square shaft portion. The rod is configured to engage with and rotate with the locking protrusion. By rotating the rod, the square shaft portion and the spring box can be moved closer together. The movement of the square shaft portion and the spring box can be easily achieved by operating the rod, which can reduce the labor burden of the operation.

[0045] In the invention of technical solution 26, a set of pivot holes are separately formed at one end of the rod. The pivot holes are configured to engage sequentially with two pivot pins located in the middle part of the escape device body. The distances between these pivot pins and the engaging protrusions are different, which allows the rotation radius of the rod to gradually increase, reliably perform rod-based breaking operations, and promotes the upward movement of the guide pin in the pin switching groove.

[0046] In the invention of technical solution 27, after the impact piece protrudes, the grip of the rod is released, and the rod can be moved back to its original position by the elasticity of the first spring and the second spring. The impact piece is set to be able to return to its original position, so that they can be reset. After a part of the laminated glass is perforated, the rod and the impact piece are returned to their original positions and reset, so that the perforation operation can be performed repeatedly and quickly.

[0047] In the invention of technical solution 28, an illumination tube is provided around the glass push plate, which enables reliable and easy breaking of laminated glass at night.

[0048] In the invention of technical solution 29, the glass breaking device has a breaking drill bit that can be rotated by fluid pressure or electric power. The breaking drill bit is provided with multiple spiral cutters or is formed into a pyramid shape, so as to pierce or break the laminated glass. The breaking force is enhanced by multiple spiral cutters, and the glass particles and powder are dispersed and discharged by forming the breaking drill bit into a pyramid shape, so as to smoothly and efficiently break the laminated glass.

[0049] In the invention of technical solution 30, the glass breaking device includes a breaking drill bit with multiple conical surfaces formed at the tip. A threaded shaft is provided at the base of the tip of the breaking drill bit. The threaded shaft is configured to be fastened to an internal threaded part provided at the end of an emergency escape device. Compared with a conical breaking drill bit, it can improve the ability to puncture or break laminated glass and can be easily installed.

[0050] In the invention of technical solution 31, the tip of the breaking drill bit is configured to collide or strike the laminated glass, and to pierce, break or destroy the laminated glass by human power, and to pierce or break the laminated glass by human power without using fluid pressure or electric power.

[0051] In the invention of technical solution 32, a breaker drill bit is installed at one end of a fire extinguisher equipped in a car. The fire extinguisher can be held with one hand and is filled with a carbon dioxide gas cylinder. The threaded shaft is fastened to the internal thread of a nut installed at the bottom of the gas cylinder, thereby making it easy to install the breaker drill bit.

[0052] In the invention of technical solution 33, a breaker drill bit is installed at one end of an emergency escape device equipped in a car. The emergency escape device is formed into a cylindrical shape and can be held with one hand. The threaded shaft is fastened to the internal thread at one end of the emergency escape device, which makes it easy to install the breaker drill bit.

After the emergency operation, the separation position is pressed outward from the operation position to push the laminated glass outward, allowing passengers to escape from the escape space between the push-out position and the installation part of the laminated glass.

Detailed Implementation

[0139] The following description describes an illustrated embodiment of an emergency escape device provided on the inside of the front door of a car using the laminated glass of the present invention. Figures 1 to 12 In the middle, 1 is an emergency escape device, which has a cylindrical escape device body 2 with a length of approximately 17cm and an outer diameter of approximately 4cm. The body 2 has a seat belt cutting device 3 at one end and a glass breaking device 4 at the other end.

[0140] The seat belt cutting device 3 is generally cylindrical, with its hollow interior connected to the front end of the escape device body 2 by a pin. A seat belt guide groove 5 is provided on its base end side. The guide surface of the seat belt guide groove 5 is inclined, and a seat belt cutter 6 is inclinedly arranged inside it, which can cut the guided seat belt B.

[0141] The escape device body 2 has a pair of outer shells 7, 7 with a roughly U-shaped cross section. The outer shells 7, 7 are connected in an opposing manner, and the rectangular space inside them houses the square shaft part 8 of the glass breaking device 4.

[0142] That is, a horizontally elongated rectangular groove 9 is formed on the inner side of the outer shell 7, and a slender rod storage groove 10 is formed on its side.

[0143] An approximately L-shaped pin engagement groove 11 is formed at the opposite position in the middle of the square shaft portion 8. A rectangular opening window is formed at the opposite position between the circumferential surface of the pin engagement groove 11 and the front end of the other side. A approximately trapezoidal engagement protrusion, described later, is provided at the opposite position at the other end of the circumferential surface.

[0144] A stepped square hole 14 is formed inside the square shaft portion 8. A first spring 15 is housed at the front end of the square hole 14, and its end is disposed in the curved portion of the pin engagement groove 11.

[0145] A spring box 16 is slidably inserted into the rear end of the square hole 14. A pin switching groove 17 is formed at the opposite position of the front end of the circumference of the spring box 16. The pin switching groove 17 is formed into a horizontal parallelogram, and a guide pin 18 is movably housed inside it.

[0146] The switching edge 17a on the rear side of the pin switching groove 17 is formed as a gentle slope, so that the guide pin 18 that moves to the switching edge 17a can move upward and be displaced upward.

[0147] A stepped hole 19 is formed inside the spring box 16, and a second spring 20 with a stronger elastic force than the first spring 15 is housed in the stepped hole 19. The spring 20 can accumulate elasticity by being pressed by the backward displacement of the square shaft portion 8.

[0148] In the pin engagement groove 11 and pin switching groove 17, the guide pin 18 is inserted from the outside of the square shaft part 8, and the square shaft part 8 and the spring box 16 are connected by the guide pin 18, so that the spring box 16 is pressed into the square shaft part 8 and hooked.

[0149] A square-shaft-shaped plate holder 21 is movably inserted into the first spring 15 as a crushing tool. A plate-shaped impact plate 22 with a tip 22a is fixed to the front end of the holder 21 via a pin 23.

[0150] A thick-walled rectangular glass push plate 24 is provided at the front end of the square shaft portion 8. A longitudinal rectangular opening 25 is formed on the end face of the push plate 24, which allows the impact piece 22 to enter and exit through the opening 25.

[0151] In each rod receiving groove 10 of the outer housing 7, a pivot 27 of the rod 26 is received in such a way that it can move in the front-back direction. Two pivot holes 28 and 29 are formed separately in the pivot 27.

[0152] The rod 26 is formed into an approximately inverted L-shape by stamping a thick-walled steel plate, and a pivot 27 is formed at its upper end by bending downward at an acute angle.

[0153] Two pivot pins 30 and 31 are separately disposed in the rod receiving groove 10, and the pivot holes 28 and 29 are configured to engage with the pivot pins 30 and 31 in sequence, with the pivot pin 30 always engaging with the pivot hole 28.

[0154] A tapered engaging portion 32 is formed on the upper part of the rod 26. The engaging portion 32 is configured to engage with a plate-shaped engaging protrusion 34 that protrudes from the rear end of the square shaft portion 8. By the displacement of the square shaft portion 8, which is always pressed forward by the second spring 20, the pivot pin 30 is forced to engage with the pivot hole 28.

[0155] The handle 33 of the rod 26 extends obliquely downward from the engaging part 32, and a plate-shaped handle retainer 34 is fixed between the handles 33 by screws.

[0156] For example Figure 10 As shown, the front door 35 is surrounded by window frames 36-38 and waistline frame 39, and the laminated glass 40 is configured to be raised and lowered from the storage section (not shown) directly below by a lifting device 42 equipped with a motor 41 between them.

[0157] Therefore, the perimeter of the laminated glass 40 is not sealed and fixed.

[0158] The laminated glass 40 has inorganic glass tempered glass plates 43 and 44 disposed on the interior and exterior, and a thermoplastic resin interlayer 45 disposed between them.

[0159] In the implementation, the thickness of the tempered glass panels 43 and 44 is 0.5 mm or more and 2.3 mm or less. The thickness of the tempered glass panel 44 on the indoor side is made as thin as possible than that of the tempered glass panel 43 on the outdoor side, which is preferred for vehicle safety and weight reduction.

[0160] In addition, the thickness of the intermediate membrane 45 is 0.2 mm or more and 2.3 mm or less, and preferably 0.3 mm or more and 1.5 mm or less. Lightweight and easy-to-handle membranes are preferred.

[0161] In the figure, 46 are multiple perforations or through marks formed by the emergency escape device 1 along the waistline frame 39 at the lower part of the laminated glass 40. 47 is a thin rubber sheet protective cover covering the opening 25 of the glass push plate 24 to prevent tiny fragments generated when the laminated glass 40 breaks from entering the opening 25, thus preventing internal malfunctions from occurring.

[0162] 48 is the passenger escape space formed by pushing the laminated glass 40 outward after it is broken to a certain extent.

[0163] The emergency escape device for automobiles of the present invention, configured in this way, has a seat belt cutting device 3 at one end of the escape device body 2 and a glass breaking device 4 at the other end, which are required for its manufacture.

[0164] The seat belt cutting device 3 is made of synthetic resin and is roughly cylindrical. The hollow part inside is assembled to the front end of the escape device body 2 and connected by a pin.

[0165] The seat belt cutting device 3 of the embodiment is configured to be able to be divided into two parts along the axial direction with the seat belt guide groove 5 as the center, and to join the various molded parts and connect them with pins, which simplifies the manufacturing process.

[0166] A seat belt guide groove 5 is formed on the base end side of the seat belt cutting device 3. The guide surface of the seat belt guide groove 5 is formed in an inclined shape, and a seat belt cutter 6 is arranged in an inclined shape inside it, so as to cut the guided seat belt B.

[0167] The escape device body 2 includes: a square-axis glass breaking device 4 made of synthetic resin, a spring box 16 that can be slidably inserted into the rear end of the breaking device 4, a set of outer shells 7, 7 assembled on the outside of the breaking device 4, and a set of rods 26 assembled on the outer shells 7, 7.

[0168] The glass breaking device 4 has a thick-walled rectangular glass pushing plate 24 protruding from its front end, with a rectangular opening 25 formed on its end face, and a square hole 14 formed inside the square shaft part 8, which houses the first spring 15 and the sheet retainer 21.

[0169] The plate retainer 21 is formed into a square shaft of steel, and a high-hardness plate-shaped impact plate 22 is riveted to its front end. In addition, a guide pin 18 is inserted into the pin hole P at the rear end to connect the plate retainer 21 and the spring box 16.

[0170] A roughly L-shaped pin engagement groove 11 communicating with the square hole 14 is formed at the opposite position in the middle of the square shaft portion 8, and a trapezoidal plate-shaped engagement protrusion 34 protrudes from the rear end.

[0171] The spring box 16 is formed into a square tube shape by resin molding, and a pin switching groove 17 is formed at its front end. The pin switching groove 17 is formed into a horizontal parallelogram, and the guide pin 18 is movably housed inside it.

[0172] The switching edge 17a on the rear side of the pin switching groove 17 is formed as a gentle bevel. Before the breakage of the laminated glass 40 based on the rotation operation of the rod 26 is about to begin, the guide pin 18 is placed on the switching edge 17a, and the guide pin 18 is moved upward to disengage from the bend and merge with the pin engagement groove 11, so that the guide pin 18 can move along the straight pin engagement groove 11.

[0173] The second spring 20 is housed in the spring box 16, and the guide pin 18 is inserted from the outside of the square shaft portion 8 into the pin switching groove 17 at the front end of the spring 20 to connect the spring box 16 and the square shaft portion 8.

[0174] As a result, the elastic energy stored in the second spring 20 is transmitted to the plate holder 21 in one go, enabling the impact plate 22 at the front end to protrude from the opening 25.

[0175] A stepped square hole 14 is formed inside the outer housing 7, which can accommodate a portion of the square shaft 8 and the spring box 16. A rod receiving groove 10 is formed through the outer side of the hole, in which two pivot pins 30 and 31 can be separately arranged.

[0176] The rod 26 is formed into an approximately inverted L-shape by stamping a thick-walled steel plate, and a pivot 27 is formed at its upper end by bending downwards at an acute angle.

[0177] A tapered engaging portion 32 is formed on the upper part of the rod 26, and the engaging portion 32 is configured to engage with a plate-shaped engaging protrusion 34 that protrudes from the rear end of the square shaft portion 8.

[0178] The rods 26, 26, thus manufactured, are inserted into the rod receiving slots 10, 10 of the outer housings 7, 7, so that the pivot holes 28, 29 engage with the pivot pins 30, 31. In addition, the engaging parts 32, 32 engage with the engaging protrusions 34, 34 on both sides of the square shaft part 8, and the handles 33, 33 are arranged to protrude downwards. A plate-shaped handle retainer 34 is fixed between the handles 33, 33 with screws.

[0179] The emergency escape device of the car assembled in this way is like Figure 1 As shown, a seat belt cutter 3 is provided at one end of the glass breaking device 4, and a glass breaking device 4 is provided at the other end. The handle 33 is provided protruding obliquely downward from the outer housing 7.

[0180] In this case, the pin engagement groove 11 in the middle part of the square shaft part 8 partially coincides with the pin switching groove 17 of the spring box 16 inserted into the square shaft part 8. A guide pin 18 is inserted into the bent part of the pin engagement groove 11 in the overlapping part, thereby pin connecting the square shaft part 8 and the spring box 16.

[0181] At this time, the spring box 16 is moved slightly toward the square shaft portion 8, compressing the first spring 15. Its elasticity acts on the rods 26 via the engaging protrusions 34, 34, causing the rods 26 to rotate counterclockwise around the engaging protrusions 34, 34, so that the pivot hole 28 presses against the pivot pin 30. This situation is as follows: Figure 1 As shown.

[0182] When using such an emergency escape device for a car, the lever 26 is rotated counterclockwise with the locking protrusion 34 as the fulcrum.

[0183] In this way, the square shaft portion 8 compresses the first spring 15 while moving toward the seat belt cut-off device 3, and the guide pin 18 moves together with it toward the rear side of the pin switching groove 17.

[0184] In addition, as the square shaft part 8 moves, the second spring 20 inside the spring box 16 is compressed, and the elasticity of the first spring 15 and the second spring 20 gradually accumulates.

[0185] If the rod 26 is rotated further in the same direction, the pivot 27 of the rod 26 moves upward, the pivot hole 28 retracts from the pivot pin 30 and is released from engagement, and in its place, the pivot hole 29 engages with the pivot pin 31.

[0186] As a result, the radius of rotation of the rod 26 with the engagement protrusion 34 as the fulcrum increases, the operating force of the rod 26 is reduced accordingly and becomes easier, and the guide pin 18 moves toward the base of the switching edge 17a of the pin switching groove 17 and begins to rise on the switching edge 17a.

[0187] Thus, when the guide pin 18 gradually moves upward along the switching edge 17a and is pulled out from the curved part of the pin engagement groove 11 and moves towards the straight part, the elastic restraining effect of the first spring 15 and the second spring 20 is released, and their combined elastic force acts on the sheet retainer 21 via the guide pin 18.

[0188] Therefore, the sheet holder 21 moves toward the front end side within the square shaft portion 8, and the impact sheet 22 pierces the protective sheet 47 and protrudes from the opening 25, which can break the inner tempered glass 44 of the laminated glass 40.

[0189] The emergency escape device 1 assembled in this way has a simple structure, with most of the structural components molded from synthetic resin. Therefore, it can be manufactured in a lightweight, easy, and inexpensive manner, and can reduce the labor burden of actual breaking operations of the laminated glass 40. In addition, due to its small size and light weight, the emergency escape device 1 can be stored in a suitable location near the front seat inside the carriage.

[0190] Next, while using the emergency escape device 1 to break the laminated glass 40 located near the front seat of the vehicle, keep the emergency escape device 1 in place, first operate the seat belt cutter 3, insert the seat belt B into its seat belt guide slot 4, and use the seat belt cutter 6 to cut the side end of the seat belt B, thereby releasing the seat belt B from the body.

[0191] Next, the push plate 24 at the front end of the square shaft portion 8 of the glass breaking device 4 is pushed and held against the tempered glass 44 surface on the lower inner side of the laminated glass 40. In this way, the fixed position of the push plate 24 is easily maintained by the friction of the protective sheet 47.

[0192] In this situation, since the emergency escape device 1 is not activated, the impact plate 22 is in a stationary position, with its tip 22a separated from the surface of the reinforced glass 44. This situation is as follows... Figure 11 As shown in (a).

[0193] In this case, the actual working location for laminated glass can be selected based on the passenger's physique, seating position, and carriage conditions.

[0194] For example, depending on the passenger's physique and seating position, the emergency work location can be selected at the lower, middle, or upper part of the laminated glass. In addition, the carriage can be tilted up, down, left, or right to allow for work to be carried out in a reasonable posture, taking into account the scattered state of the carried goods.

[0195] Then, when the strength of the laminated glass decreases at the working position during the operation, the separated position, such as the upper or lower position or the middle position of the working position, is pressed outward to push the laminated glass outward, thereby reasonably forming an escape space 48.

[0196] In such an emergency operation, if the emergency escape device 1 is operated, the impact piece 22 will pierce the protective piece 47 and protrude from the opening 25, colliding with the reinforced glass 44 on the inner side of the laminated glass 40.

[0197] Therefore, a crack forms in the reinforced glass 44 and propagates to the surrounding area, causing the reinforced glass 44 to break. This situation is as follows... Figure 11 As shown in (b).

[0198] In this case, since the cross-section of the impact piece 22 is a long rectangular shape and compact, the impact force and friction force on the tempered glass 44 are small, which can reduce the elasticity of the first spring 15 and the second spring 20 required for it.

[0199] At this time, the tiny fragments generated by the damage to the tempered glass 44 are prevented by the protective plate 47 from intruding into the square shaft portion 8, thus preventing blockage of the impact plate 22 and the plate retainer 21, thereby maintaining smooth operation.

[0200] Subsequently, the impact piece 22 moves further inward toward the inner side of the laminated glass 40, and upon reaching the interlayer 45, the relatively soft interlayer 45 is rapidly broken. This situation is as follows... Figure 11 As shown in (c).

[0201] After the intermediate film 45 is damaged, the impact piece 22 moves toward the outer tempered glass 43, penetrates the glass 43 to form a crack, and propagates it to the periphery to damage the tempered glass 43.

[0202] The situation is as follows Figure 11 As shown in (d).

[0203] Thus, when the impact piece 22 penetrates the laminated glass 40, a longitudinally elongated rectangular perforation mark 46, approximately the same shape as the cross-section of the impact piece 22, is formed through the laminated glass 40. This situation is as follows... Figure 11 As shown in (e).

[0204] Thus, after the perforation of one part of the laminated glass 40 is completed, the grip of the lever 26 is released.

[0205] In this way, the rod 26 returns to its original position due to the elasticity of the first spring 15 and the second spring 20. Additionally, the plate retainer 21 is pulled back into the square shaft portion 8, thereby causing the impact plate 22 to return to its original position within the square shaft portion 8, resetting to its original position. Figure 1 The state.

[0206] Then, the push plate 24 of the emergency escape device 1 is moved toward other positions close to the perforation mark 46, and the same perforation operation as described above is performed to form other perforation marks 46. Afterward, this operation is repeated to form a broken area sufficient to form the escape space 48 described later.

[0207] When the fracture zone of the laminated glass 40 is increased in this way, the strength of the fractured part gradually decreases.

[0208] Therefore, when the laminated glass 40 separated from the broken part is pressed from the outside of the carriage, the remaining interlayer 45 is easily bent outwards due to the softness of the interlayer 45 left by this action.

[0209] Then, an escape space 48 is formed between the bent position and the partition space of the window frame 36-38, which serves as the mounting part of the laminated glass, allowing passengers to escape. This situation is as follows: Figure 12 As shown.

[0210] In this situation, as described above, the actual working position for the laminated glass is selected based on the passenger's physique, seating position, and carriage conditions, and the operation is carried out in a reasonable posture. If the strength of the working position of the laminated glass decreases, or if the laminated glass detaches from the surrounding mounting parts due to the impact of emergency operation, when its restraint becomes slow, its separation position, such as the upper position, lower position, or middle position of the working position, is pressed outward to push the laminated glass outward to form an escape space.

[0211] In this case, the emergency operation combines a single operation or multiple operations in a continuous manner, thereby reducing the intensity of the operation location.

[0212] Thus, the emergency escape device 1 according to the first embodiment, although small, lightweight and simple in construction, can make the impact plate 22 obtain a strong piercing force or breaking force through the elasticity of the first spring 15 and the second spring 20, thereby breaking the laminated glass 40, and the breaking operation can be easily and quickly performed by a simple triggering operation based on the rod 26.

[0213] In addition, according to the emergency escape method, the emergency operation is carried out on the front seat door 35, which is not completely fixed around it. After the door breaks as specified, the front seat door 35 is pressed from the side of the carriage and bent outward to form an escape space 48 for passengers, thus achieving escape. Therefore, the structure of the front seat door 35 and the laminated glass 40 can be used to achieve this.

[0214] Figures 13 to 50 Other embodiments of the present invention are indicated by reference numerals, and the same reference numerals are used for the components corresponding to the embodiments described herein. Figures 13 to 17 The second embodiment of the present invention is shown, in which a seat belt cutting device 3 and a glass breaking device 4 are arranged at both ends of the square shaft portion 8, and a first spring 15 and a second spring 20 are housed inside the square shaft portion 8.

[0215] The structure and function of this embodiment are essentially the same as those of the embodiment described above. The spring box 16 is connected to the square shaft portion 8 via the guide pin 18. The spring box 16 is pressed into the square shaft portion 8 to compress the second spring 20 inside. In addition, the first spring 15 is compressed to store their elasticity.

[0216] The guide pin 18 is inserted into the pin engagement groove 11 and the pin switching groove 17. The guide pin 18 is always positioned in the curved part of the pin engagement groove 11, so that it moves together with the movement of the spring box 16 and moves along the switching edge 17a, and can move from the curved part toward the straight groove.

[0217] At this time, the combined elastic force of the first spring 15 and the second spring 20 is applied to the guide pin 18, causing it to act on the plate holder 21, so that the plate holder 21 protrudes and the impact plate 22 can protrude from the opening 25.

[0218] In this embodiment, the rod 26 is formed into a roughly L-shaped form, and one end of it is connected to the square shaft portion 8 via a pin 50 so that it can rotate. The base end portion 26a of the rod 26 is configured to engage with the end of the spring box 16, thereby simply forming a sheet retainer 21. This sheet retainer can be manufactured cheaply and reasonably, and its mass production can be achieved.

[0219] Figures 18 to 20 The third embodiment of the present invention is shown. In this embodiment, instead of piercing the laminated glass 40 by colliding the impact piece 22, which is the piercing tool 22, a high-hardness piercing drill bit 51 is used as the piercing tool 22 and is rotatably mounted on the cylinder 52, so that the laminated glass 40 can be pierced or broken.

[0220] The crushing drill bit 51 has multiple spiral cutter heads 51a on its cylindrical surface to enhance the crushing force. A cover 53 is installed at the end of the cylinder body 52. ​​A disc spring 55 is telescopically arranged between the flange 54 at the base of the crushing drill bit 51 and the cover 53. The crushing drill bit 51 is given a swinging and rotating motion when it is driven into the laminated glass 40 by the elastic telescopic action of the disc spring 55, which can crush or puncture the surface of the laminated glass 40.

[0221] In this case, in order to enable the oscillating rotation of the breaker bit 51 to operate for a long time, a motor that can be driven by a vehicle power supply can also be connected to the breaker bit 51.

[0222] In addition, a gas cylinder filled with approximately 4 MPa of carbon dioxide (not shown) is disposed behind the flange 54. When the sealing plate of the gas cylinder (not shown) is broken at a specified time, the carbon dioxide can be sprayed toward the spiral cutter head 51a, which can enhance the rotational force of the crushing drill bit 51 and improve the crushing capacity.

[0223] Figure 21 This represents the fourth embodiment of the present invention, in which the crushing drill bit 51, which serves as the crushing tool 22, is formed into a pyramidal shape, thereby dispersing and removing the glass particles and powder 56 along with the crushed laminated glass 40, and smoothly and efficiently crushing the laminated glass 40.

[0224] Figure 22 This invention represents a fifth embodiment in which an illumination tube 57 is installed on the outside of the glass push plate 24 to illuminate the area around the glass push plate 24, enabling safe and reliable nighttime breaking operations.

[0225] The lighting tube 57 has multiple LEDs that can flash using a built-in DC power source (dry cell battery), and these LEDs can be switched on and off using a switch (not shown).

[0226] The lighting tube 57 is substantially the same as the lighting tube disclosed in Japanese Patent No. 5757939 filed by the applicant.

[0227] In addition to the impact method based on the impact tool and the breaking method based on the rotating tool, the laminated glass 40 can also be broken by means of pressurized fluids such as compressed air or high-pressure water, ultrasonic irradiation, vibration damage based on repeated elastic vibration, melting method based on laser or microwave lasing beam or electromagnetic wave irradiation, cutting by pressing and cutting along the window frame 36, 38 with a sharper can opener-shaped manual breaking tool, breaking by continuously impacting the periphery of the laminated glass 40 with a small power tool such as a pneumatic hammer, or continuously cutting the periphery of the laminated glass 40 with a rotating power tool such as a chainsaw.

[0228] Figures 23 to 29 This invention represents a sixth embodiment, illustrating a novel breaking device 58 preferred for breaking laminated glass 40. The breaking device 58 is applied to a fire extinguisher mounted on a vehicle. The fire extinguisher is filled with a small, lightweight carbon dioxide cylinder 59 (approximately 4 MPa) as the extinguishing gas. A needle (not shown) is provided inside a sealing device 60 housing the cylinder 59, capable of breaking the sealing plate (not shown) of the cylinder 59. An outline of the fire extinguisher is disclosed in Japanese Patent No. 5148623, filed by the applicant.

[0229] On the side of the sealing device 60, the seat belt guide groove 61 is formed in an inclined shape and opens downward. A seat belt cutter 62 is disposed inside the seat belt guide groove 61 above it, which can cut the seat belt 63 inserted into the seat belt guide groove 61.

[0230] In the figure, 64 is a sealing lifting button located at the upper end of the sealing breaking device 60. Pulling the sealing lifting button 64 to the side will open the safety plate 65 connected to the sealing lifting button 64. Through the free space of the safety plate 65, the sealing lifting button 66 can be pressed down, and the inclined tube (not shown) at the lower end of the sealing rod (not shown) connected to the sealing lifting button 66 can be inserted into the sealing plate, thereby breaking the seal of the sealing plate.

[0231] As a result, carbon dioxide gas filled in the gas cylinder 59 can be ejected, and the carbon dioxide gas can be ejected from the nozzle (not shown) and blown toward the fire source (not shown).

[0232] In the figure, 67 is the gripping part of the concave curved surface located at the lower part of the sealing device 60.

[0233] A mounting nut 68 is welded to the bottom surface of the gas cylinder 59 as a crushing tool 22, and a crushing drill bit 70 is mounted on the internal thread 69 of the nut 68.

[0234] The breaker drill bit 70 is formed into a roughly arrowhead shape from alloy tool steel (SKD11) with excellent wear resistance, and its tip 70a is hardened to achieve high hardness.

[0235] The tip 70a has a generally roof-shaped small drill bit 71 arranged back-to-back, with a steep ridge 72 dividing its joint edge, and a shorter ridge 74 derived from its top 73. In addition, ridges 75 and 76 branch in two directions from the lower end of ridge 74, and ridges 76 and 76 branch in two directions from the lower end of ridge 72.

[0236] Then, a steep conical surface 77 is formed between the ridges 72, 74, 75, and 76, and one side of the ridges 75 and 76 is vertically cut off to form a vertical surface.

[0237] A threaded shaft (screw) 78 is formed at the lower part of the tip 70a, which can be fastened to the internal thread 69.

[0238] Since the breaking drill bit 70 forms the tip 70a into a polyhedron through multiple conical surfaces, it can exert impact forces on automotive glass in multiple directions to promote breaking and perforation, compared with conventional conical or pyramidal tips, thus enabling efficient and rapid breaking of laminated glass 40.

[0239] Therefore, the breaking device 58 equipped with the breaking drill bit 70 can quickly break the laminated glass 40, enabling passengers to escape from the carriage quickly.

[0240] In addition, the breaker bit 70 is easily installed by screwing the threaded shaft 78 into the internal thread portion 69, thus eliminating the need for the complex operation of forming an annular groove on the circumference of the mounting shaft and fitting a retaining ring into the groove, as was done previously.

[0241] Figures 30 to 32 This invention represents a seventh embodiment, which illustrates a novel breaking device 79 preferred for breaking laminated glass 40. The breaking device 79 is applied to an emergency escape device mounted on a vehicle, which is housed in an upright position inside the vehicle's door pocket (not shown). An outline of the emergency escape device is disclosed in Japanese Patent No. 6811122, filed by the applicant.

[0242] The emergency escape device is generally cylindrical, with a seat belt guide groove 61 formed at one end at an angle. A seat belt cutter 62 is disposed inside the seat belt guide groove 61, which can cut the seat belt inserted into the seat belt guide groove 61 (illustration omitted).

[0243] At the other end of the emergency escape device, a breaker drill bit 70, which is the main part of the breaker device 79, is installed. The breaker drill bit 70 fastens the threaded shaft 78 to the internal thread portion 82 formed on the bolt head 81, which is integral with the support rod 80 arranged axially inside the cylinder of the emergency escape device.

[0244] In the figure, 83 is a cylindrical guide disposed on the outside of the support rod 80, with spacers 84 and 85 disposed at its upper and lower ends, and a nut 86 disposed on the spacer 84 that is threadedly connected to the threaded shaft of the support rod 80.

[0245] A helical spring-shaped counterweight 97 is disposed inside the cylindrical guide 83. Its weight enhances the inertial force when the emergency escape device is used, thereby enhancing the impact of the breaker bit 70.

[0246] A hollow cylindrical drill bit pressing member 87 is disposed on the outside of the bolt head 81, and a cylindrical rubber protective cover 88 is disposed between the drill bit pressing member 87 and the bolt head 81. The front end of the protective cover 88 protrudes outward from the cylinder body and always surrounds the breaker drill bit 70 to avoid contact with fingers.

[0247] Then, during the breaking of the laminated glass 40 based on the breaking drill bit 70, as... Figure 32 As shown, the front end 88a of the protective cover 88 is bent to expose the tip of the breaking drill bit 70, so that it can come into contact with the surface of the laminated glass 40.

[0248] In the figure, 89 is a convex part formed axially on the circumferential surface of the cylinder along the seat belt guide groove 61, and 90 is an annular groove formed on the circumferential surface of the middle part of the cylinder, which is equipped with an O-ring 91, thereby making it easier to hold the cylinder of the emergency escape device.

[0249] The crushing device 79 has the crushing drill bit 70 at its tip, so compared with conventional crushing devices with conical or pyramidal tips, it can apply impact force to automotive glass in multiple directions to promote crushing and perforation, and can efficiently and quickly crush laminated glass 40.

[0250] Therefore, the breaking device 79 equipped with the breaking drill bit 70 can quickly break the laminated glass 40, enabling passengers to escape from the carriage quickly.

[0251] Figures 33 to 39 The eighth embodiment of the present invention is shown, which illustrates a novel breaking device 92 preferred for breaking laminated glass 40. This breaking device 92 is applied to a fire extinguisher mounted on a vehicle, which is substantially the same as the fire extinguisher of the sixth embodiment; therefore, common components are labeled with the same reference numerals, and their descriptions are omitted.

[0252] In this embodiment, a mounting nut 68 is welded to the bottom surface of the gas storage cylinder 59 as a crushing tool 22, and a crushing drill bit 93 is mounted on the internal thread 69 of the nut 68.

[0253] The breaker bit 93 is formed from alloy tool steel (SKD11) with excellent wear resistance in a roughly semi-grind shape, and its tip 93a is hardened to achieve high hardness.

[0254] That is, the front shape of the tip 93a is slightly longer than a roughly semi-circular shape, and the two sides of its circumference are formed into acute-angled cones 94. A flat surface 95 is formed parallel to the outside of the cones 94, thereby achieving thinness and light weight.

[0255] A threaded shaft 78 is formed at the lower part of the tip 93a, which can be fastened to the internal thread 69.

[0256] The breaking drill bit 93 has acute-angled conical surfaces 94 on both sides of the tip 93a and roughly arc-shaped periphery. Therefore, compared with the conventional conical or pyramidal tip, it can exert a stronger impact force on the automotive glass over a wide area to promote breaking and perforation, and can efficiently and quickly break the laminated glass 40.

[0257] Therefore, the breaking device 92 equipped with the breaking drill bit 93 can quickly break the laminated glass 40, enabling passengers to escape from the carriage quickly.

[0258] Figure 40 as well as Figure 41 This represents the ninth embodiment of the present invention, which shows a novel breaking device 96 preferred for breaking laminated glass 40.

[0259] The breaking device 96 is applied to an emergency escape device mounted on a vehicle, which is stored in an upright position inside the vehicle's door pocket (not shown). The outline of the emergency escape device is substantially the same as that of the emergency escape device in the seventh embodiment; therefore, common components are labeled with the same reference numerals, and their descriptions are omitted.

[0260] The breaking drill bit 93 in this embodiment is the same as the breaking drill bit 93 in the eighth embodiment. Its tip 93a has acute-angled conical surfaces 94 on both sides and its periphery is roughly arc-shaped. Therefore, compared with the conventional conical or pyramidal tip, it can exert a stronger impact force on the automotive glass over a wide area to promote breaking and perforation. Thus, it can break the laminated glass 40 efficiently and quickly.

[0261] Therefore, the breaking device 96 equipped with the breaking drill bit 93 can quickly break the laminated glass 40, enabling passengers to escape from the carriage quickly.

[0262] Figures 42 to 48 This indicates the tenth embodiment of the present invention, which shows a novel breaking device 98 preferred for breaking laminated glass 40. The breaking device 98 is applied to a fire extinguisher mounted on a vehicle, which is substantially the same as the fire extinguisher of the sixth embodiment; therefore, common components are labeled with the same reference numerals, and their descriptions are omitted.

[0263] In this embodiment, a mounting nut 68 is welded to the bottom surface of the gas storage cylinder 59 as a crushing tool 22, and the external thread 78 of the crushing drill bit 99 is fastened to the internal thread 69 of the nut 68.

[0264] The breaker drill bit 99 is formed into a roughly rectangular shape from alloy tool steel (SKD11) with excellent wear resistance, and its tip 99a is hardened to achieve high hardness.

[0265] The tip 99a forms a roof shape by intersecting the conical surfaces 100 and 100 at the front end of the approximately house-shaped cross section, and cuts it out vertically on all four sides, so that the vertical surface 101 of the horizontal rectangle and the vertical surface 102 of the house shape are respectively arranged opposite each other.

[0266] A threaded shaft 78 is formed at the lower part of the tip 99a, which can be fastened to the internal thread 69.

[0267] The breaking drill bit 99 has a tip 99a with a plurality of acute-angled conical surfaces 99 and a vertical surface 102 at the front end. The surrounding area is vertically cut off to form a horizontally elongated rectangular vertical surface 101 and a pyramidal vertical surface 102. Therefore, compared with the conventional conical or pyramidal tip, it can exert a stronger impact force on automotive glass to promote breaking and perforation, and can efficiently and quickly break laminated glass 40.

[0268] Therefore, the breaking device 98 with the breaking drill bit 99 can quickly break the laminated glass 40, allowing passengers to escape from the carriage quickly.

[0269] Figure 49 as well as Figure 50 This describes the eleventh embodiment of the present invention, which shows a novel crushing device 103 preferred for crushing laminated glass 40.

[0270] The breaking device 103 is applied to an emergency escape device mounted on a vehicle, which is stored in an upright position inside the vehicle's door pocket (not shown). The emergency escape device in this embodiment is substantially the same as the emergency escape device in the seventh embodiment; therefore, common components are labeled with the same reference numerals, and their descriptions are omitted.

[0271] The breaking drill bit 99 in this embodiment is the same as the breaking drill bit 99 in the tenth embodiment. Its tip 99a has acute-angled conical surfaces 100 on both sides, and its surrounding area is vertically cut to form a horizontally elongated rectangular vertical surface 101 and a pyramidal vertical surface 102. Therefore, compared with the conventional conical or pyramidal tip, it can exert a stronger impact force on the automotive glass over a wide area to promote breaking and perforation, thus enabling efficient and rapid breaking of laminated glass 40.

[0272] Therefore, the breaking device 103 equipped with the breaking drill bit 99 can quickly break the laminated glass 40, enabling passengers to escape from the carriage quickly.
