Description

  The present invention relates to an emergency escape tool for use in an automobile accident or the like, and an emergency safety flame cylinder equipped with the tool.

  Many emergency tools for occupants to get out of the car in the event of an automobile accident, such as hammers that break the window glass of automobiles, scissors and blades that cut the seat belt, are sold.

  In addition, emergency tools that combine these conventional functions are also sold, and genuine auto parts and the like that combine hammers and scissors are also provided by automakers.

  For example, Patent Literature 1 proposes an emergency tool in which scissors are housed in a hollow portion provided in a main body having a hammer portion at the tip for breaking glass. As a result of combining different functions, each function can be stored compactly without having to be equipped separately. However, in this case, in addition to the already equipped emergency safety flame cylinder, it is necessary to equip it separately, and as a result, there is a problem that the number of storage locations for emergency safety parts increases.

  Moreover, as what combined the function of a flame cylinder and glass destruction etc. combining with the conventional emergency security flame cylinder, for example, in patent document 2, it had the collar part for glass destruction at the edge part of a flame cylinder. An in-vehicle bag provided with a handle portion has been proposed, and can be stored without increasing the number of storage locations for emergency safety parts. However, in this case, the buttocks are exposed, for example, in the short direction of the flame tube installed at the feet of the passenger seat, and there is a risk that the occupant may be injured. In addition, there is a problem that it may be necessary to provide a separate storage place without completely entering the storage space of the conventional emergency safety flame cylinder.

  Further, for example, Patent Document 3 proposes an emergency tool having a crowned portion at the end of the flame tube, and sandwiching the hammer portion with the crowned portion formed of a pair of parts, the Built-in is realized. However, when recycling is considered as an environmental measure, the sandwiching structure has a problem in that it takes time to separate the crown portion and the hammer portion, which are different materials.

  Furthermore, in recent years, for example, low-cost hammers using soft iron or the like, high-quality hammers using a kind of cemented carbide, and the like have been provided. However, in the case of soft iron or the like, the hardness is low and it can withstand only one glass breakage, which is problematic from the viewpoint of durability. Moreover, there is a case where the glass cannot be reliably broken by a single operation. Further, in the case of cemented carbide or the like, since it has a very high hardness, it can withstand repeated use, but there is a problem that the cost increases.

JP-A-6-179179 Japanese Patent Laid-Open No. 10-296659 JP-A-7-237523

  The present invention has been made in view of the above points, and it is not necessary to increase the number of emergency safety parts and storage locations separately by incorporating it into an emergency safety flame cylinder that has already been provided, and the flame flame cylinder of the buttocks A low-cost emergency escape tool that has no exposure in the short-side direction, is less likely to cause injury to passengers, is highly recyclable, can be used repeatedly, and an emergency safety flame cylinder for an automobile equipped with the same It is an issue to provide.

  In order to solve the above-mentioned problem, the emergency escape tool according to the first aspect of the present invention is an emergency escape tool 1 having a crowning portion 4 on the end of a flame cylinder, which is made of tempered glass such as an automobile. The hammer portion 5 for breaking is provided so as to face the longitudinal direction of the flame tube.

  The emergency escape tool according to claim 2 is the invention according to claim 1, wherein the hardness of the hammer portion 5 provided in the emergency escape tool 1 is 60 HRC or more in Rockwell hardness. It is characterized by this.

  The emergency escape tool according to claim 3 is the invention according to claim 1 or 2, wherein the end of the hammer portion 5 provided in the emergency escape tool 1 is threaded 6. The hammer portion 5 can be screwed onto the emergency escape tool body 3.

  Furthermore, an emergency safety flame cylinder for an automobile according to a fourth aspect of the invention includes the emergency escape tool 1 according to any of the first to third aspects of the invention. .

  The effects of the present invention will be described. According to the invention of claim 1, the emergency escape tool 1 equipped with the hammer portion 5 can be integrated with the emergency safety flame cylinder for automobiles, which is conventionally required to be equipped, by being crowned. The emergency safety flame cylinder 2 for an automobile with 1 (hereinafter referred to as “flame cylinder with tool”) can be created. In this case, the whole of the flame cylinder with a tool becomes a hitting body of the hammer portion 5, and as a result, the entire weight of the flame cylinder with a tool can be set as the impact force. In this case, it is not necessary to perform a gesture of swinging down in a narrow space like a conventional T-shaped hammer. Of course, in the flame tube with a tool, the glass can be easily broken even if it is swung down like a T-shaped hammer or the operation of hitting the hammer portion 5 against the glass using a wrist snap. Is possible.

  According to invention of Claim 2, in addition to said effect, it becomes possible to destroy reliably the tempered glass for side windows of a motor vehicle by one operation. Like conventional low-priced hammers using soft iron, etc., it can withstand only one glass breakage due to its low hardness, and it cannot reliably break the glass in one operation. In the event of an emergency, for example, after destroying the side window on the driver's side, this time, the passengers can quickly At the same time, it is possible to escape from the vehicle. Furthermore, it is possible to keep the cost low without causing an increase in cost as in the case of a high quality hammer using a kind of cemented carbide.

  According to the invention of claim 3, in addition to the effects of claims 1 and 2, the separation of the emergency escape tool body 3 and the hammer portion 5 when, for example, it is recovered at the time of renewal due to the expiration of the use of the flame tube. This makes it easy to produce a flame tube with a tool that is highly recyclable.

  In the present invention, the material of the hammer portion 5 may be anything as long as it has a Rockwell hardness of 60 HRC or higher. Further, the size of the hammer portion 5 is preferably 5 to 27 mm in diameter and 5 to 50 mm in length. If the diameter exceeds 27 mm, it will exceed the diameter of the emergency safety flame cylinder 2 for automobiles. Therefore, the strength against impact at the time of breaking the glass cannot be maintained, and if the length exceeds 50 mm, it will be an obstacle when installed in the vehicle. And there is a problem. Conversely, if the diameter and length are less than 5 mm, it is difficult to reliably hit the hammer portion 5 against the glass surface, which is problematic. Further, the material of the emergency escape tool body 3 may be anything as long as it has a hardness and strength that can withstand the impact caused by the impact on the window glass, regardless of the molding method.

  Hereinafter, the present invention will be described based on examples. In addition, this invention is not limited at all by the Example.

Example As shown in FIG. 1 to FIG. 5, the other end of a tool body 3 for emergency escape made of high-density polyethylene resin having a crown 4 and having a hardness capable of withstanding the impact of hitting a window glass. A hammer part 5 (diameter 13 mm, length 17 mm) made of carbon tool steel having a Rockwell hardness of 65 HRC and having a threaded part 6 at its end is screwed to produce an emergency escape tool 1. .

  Next, the crown part 4 of the produced emergency escape tool 1 is fitted to the end of the existing emergency safety flame cylinder 2 for automobiles (Super High Flare 5; manufactured by Nippon Carlit Co., Ltd.) of JIS standard (D5711). By doing this, an emergency safety flame cylinder 2 for an automobile equipped with the emergency escape tool 1 was obtained.

  The automobile emergency safety flame cylinder 2 equipped with the assembled emergency escape tool 1 has no change in the automobile emergency safety flame cylinder 2 itself, so that it can be directly attached to an existing mounting base at a predetermined position of the automobile. It was possible. Therefore, since it is a conventional installation method, it does not get in the way and does not impair the beauty. Since the emergency safety flame cylinder for automobiles is usually installed in an easily understandable place at the same position in the vehicle, naturally, the emergency emergency flame cylinder for automobiles 2 equipped with the emergency escape tool 1 can be easily found in an emergency. It is possible.

  Next, the central part of the automobile emergency safety flame cylinder 2 equipped with the assembled emergency escape tool 1 is gripped like an ice pick, and the hammer part 5 is an ordinary passenger car (2002 wagon type car; Toyota Motor Corporation). ) And the driver's side window (tempered glass, thickness 5 mm; manufactured by a domestic glass manufacturer), the window glass is easily destroyed with a single operation, helping with its own weight and the hardness of the hammer. I was able to. Furthermore, after destroying the passenger side side window (tempered glass, thickness 5 mm; manufactured by a domestic glass manufacturer) using the emergency safety flame cylinder 2 for automobiles equipped with the same emergency escape tool 1, Even when the same replacement glass as the driver's side window (tempered glass, thickness 5mm; manufactured by a domestic glass manufacturer) was repeatedly broken five times, it could be easily broken without being inferior to the first time. .

Comparative Example Except for using an emergency tool having a soft iron hammer part (35 HRC in Rockwell hardness) at the end of a polypropylene resin handle having the same size as the emergency safety flame cylinder for automobiles used in the examples. Were tested as in the examples.

  Using this emergency tool, the driver side window (tempered glass, thickness 5mm; domestic glass manufacturer) of a normal passenger car (2002 wagon type car; manufactured by Toyota Motor Corporation) is used in the same manner as in the example. When struck, a strong force was required to break the glass, and the tip of the hammer part once used was crushed by the impact on the glass, and it was impossible to break the same type of glass. .

  INDUSTRIAL APPLICABILITY The present invention can be used as an emergency escape tool used in an automobile accident or the like and an emergency safety flame cylinder provided with the tool.
