Description

  The invention of this application relates to the main points, and particularly belongs to the technical field related to the main points of the fan. Further, a head having a head formed in advance at one end belongs to a technical field related to rivets or eyelets.

  When attention is paid to the essentials of a fan, there are many cases where a solid shaft made of metal or thermosetting resin is applied (Japanese Utility Model Publication No. 49-124247 (Patent Document 1)). Such a fan cannot be attached to a strap. Not only straps and decorative strings, but also straps with various decorations cannot be attached. This is because the main point is the solid axis. Certainly, there is a fan that can be attached with a strap or strap, and Japanese Utility Model Publication No. 42-18236 (Patent Document 2) discloses a key with a hole, but the material of the key is also a mounting means. Is also unknown. Folding fans are also known that have a ring attached to the end, which can be used to attach straps and decorations. However, from the point of view of simplicity, this is not a decoration hobby.

  On the other hand, when looking at rivets and eyelets, it is difficult to say that wearing a thermoplastic synthetic resin is always easy. The utility model registration No. 3070906 (patent document 3) is a synthetic resin, but its caulking operation is not clear and the finished shape is quite complicated. Moreover, JP, 2005-7124, A (patent documents 4) can be mentioned as an example of a synthetic resin eyelet.

As described above, the patent documents are as follows.

  The present invention has been achieved in view of the above-mentioned actual situation, and by using the cylindrical thermoplastic synthetic resin effectively, it is applied to the main points, particularly the main points of the fan, and the attachment of the lanyard and the decoration while ensuring the strength. A simple fan is provided by a simple manufacturing method, and rivets and eyelets are provided to aim for something meaningful.

In order to solve the above problems, the present invention has been made by paying attention to the unique behavior of the tube when the end of the thermoplastic synthetic resin tube is heated. of manufacturing a hollow cylindrical member, followed by air cooling after melting by heating the two end portions, characterized by comprising a bevel-shaped crimping portion of the mushroom naturally formed.

  The present invention is further characterized in that the key is a key of a fan.

The present invention further relates to construction of the rivet, and umbrella-shaped head and the cylindrical shaft portion of the mushroom is a thermoplastic synthetic resin tube rivets which are integral to heat the end portion of the cylindrical shaft portion by naturally cooling after melting Te, characterized in that the natural form of umbrella-like caulking portion of mushrooms can be achieved.

  The present invention is further characterized in that the rivet is an eyelet.

  The present invention is further characterized in that a plurality of the rivets and a lighter are packaged together as a set and are ready for sale.

The user, the sense of the needed strap of string or decoration with hanging and the holes are not empty or you is not gonna even want to put a like mascot,. This is because many fans have used solid axes. It is presumed that the strength is taken into account, but it is well known that the strength of the solid shaft and the strength of the hollow shaft do not change as much as one might think. More than that, usually the fan paper gets dirty or torn before it gets damaged. Therefore, by using a simple method, that is, by adopting a thermoplastic synthetic resin hollow shaft at the core of the fan in the present invention and simplifying the caulking work, it is inferior to that using a solid shaft . Along with providing a fan of no strength, string or decoration with the strap hanging in the sense, or if provided to those who wish to install and mascot and key, it can be expected to profound effects such as fan of usability is woefully well .

  Also, if used as a rivet or eyelet, the strength may be reduced compared to a metallic one, but the caulking work using the characteristics of the thermoplastic synthetic resin is very simple, so it can be combined with a lighter and an assembly. For sale, the role of rivets and eyelets can be completed by the lighter acting as a caulking tool. In selling, the lighter should use a piezo-electric element rather than one that uses a pyrotechnic stone. Of course, when applied to strong materials, it should be alerted to fire.

  A mushroom-shaped caulking portion is naturally formed by heating and melting both ends of a hollow cylindrical member made of thermoplastic synthetic resin and cooling it.
