【考案の詳細な説明】
本考案は走行玩具の車体に関し、特に、アルミ
ニウムの冷間鍛造により成形する車体において車
台との取付部の構造を提供するものである。[Detailed Description of the Invention] The present invention relates to a vehicle body for a running toy, and in particular provides a structure for a mounting portion to a chassis in a vehicle body formed by cold forging aluminum.
従来、アルミニウムの冷間鍛造によつて車体を
形成する場合、車台を取付けるためのボスを一体
的に突設することが困難であつた。 Conventionally, when forming a vehicle body by cold forging aluminum, it has been difficult to integrally provide a protruding boss for attaching a chassis.
一方、アルミニウムの車体は仕上製品の外観装

樹脂の肉厚を厚くすることによつて剛性を向上で
きる反面、成形時の熱によつてアルマイト処理部
にヒビ割れが生ずる等の欠点が生じてしまう。 On the other hand, aluminum car bodies are subjected to alumite treatment to improve the appearance decoration and corrosion resistance and hardness of the finished product. The above-mentioned problem can be solved by protruding a chassis mounting boss by insert molding synthetic resin on the car body to which such alumite treatment is applied, but it is possible to solve the above problem by increasing the thickness of the insert molded synthetic resin. Although rigidity can be improved by molding, there are drawbacks such as cracking in the alumite treated part due to heat during molding.
本考案は上記従来技術の問題点を除去すること
を目的とする。 The present invention aims to eliminate the above-mentioned problems of the prior art.
以下、図面に示す一実施例に基いて本考案を説
明する。 Hereinafter, the present invention will be explained based on an embodiment shown in the drawings.

の車体１の表面は、外観装飾と耐蝕性および硬度
を高めるために、アルマイト処理が施される。 In FIGS. 1 and 2, reference numeral 1 denotes a vehicle body mounted on the upper part of the chassis of a traveling toy, and this vehicle body 1 is formed by cold forging of aluminum. In this cold forging process, openings 1a are punched out in each window portion of the vehicle body by press working. The surface of the vehicle body 1 is subjected to alumite treatment in order to decorate the exterior and improve corrosion resistance and hardness.

ら透明、もしくは適当な色の合成樹脂のインサー
ト成形により窓部材２が一体成形される。この窓
部材２の成形にあたり、その天井部１ｂに面して
適当な面積の肉抜き２ｂが形成される。 A window member 2 is integrally molded into the opening 1a of the vehicle body 1 from the inside of the vehicle front 1 by insert molding of a transparent or appropriately colored synthetic resin. When forming the window member 2, a hollow 2b of an appropriate area is formed facing the ceiling portion 1b.
また、前記窓部材２の周辺部には車体１の前後
方向に部分的に連なる連設部２ａが形成され、こ
れら連設部２ａの端部にはおのおの車台５を取付
けるためのボスが一体的に突設されている。 Further, a continuous portion 2a is formed in the peripheral portion of the window member 2 and is partially continuous in the longitudinal direction of the vehicle body 1, and a boss for attaching the chassis 5 is integrally formed at the end of each of the continuous portions 2a. It is installed protrudingly.
また、前記連設部２ａ下面にはボス３にかけ
て、この連設部を補強するための補強リブ４が一
体成形されている。 Furthermore, reinforcing ribs 4 are integrally formed on the lower surface of the continuous portion 2a to extend over the boss 3 and to reinforce the continuous portion.
以上のように、本考案によれば、アルミニウム
の車体１にたいして別個に合成樹脂等で窓部材を
成形する必要がなく、インサート成形により一体
的に窓部２が形成されるので、部品点数が少くな
り、その組立も不要となり、工程を単純化でき
る。 As described above, according to the present invention, there is no need to separately mold the window member with synthetic resin or the like on the aluminum car body 1, and the window part 2 is integrally formed by insert molding, so the number of parts is reduced. This eliminates the need for assembly, simplifying the process.
さらに、この窓部２の成形にあたり、車体天井

ことにより所望の機械的強度を確保することがで
きる。 Furthermore, when forming the window part 2, a hollow part 2b is formed in the part 2b corresponding to the car body ceiling part 1b, so that there is almost no synthetic resin in the aluminum car body 1 except for the window part 2. This can prevent the alumite treatment from cracking due to heat during integral molding of the synthetic resin. Moreover, the mounting bosses 3, 3 are integrally molded together with the continuous portion 2a that is continuous with a part of the window member 2, and while the thickness of the synthetic resin in this portion is minimized, the boss portions 3, 3 are A desired mechanical strength can be ensured by providing reinforcing ribs 4, 4 in a protruding manner.
