[Prior Art] Children's roller skates generally include a round frame / which is only used for relatively short children's shoes in length, or has the same structural characteristics. Therefore, it is customary for children's roller skates to bolt the wheel frame to the sole with a receiving hole for a front axle and a rear axle, and the front and rear axles are supported by a support The frame is inserted into the receiving hole and is tightly bolted. Two roller trains are supported by roller (ball) bearings in a freely rotatable manner on each axle fixed to the support frame. In addition, the metal wheel frame has a relatively heavy weight, which is particularly disadvantageous for children's skates. The support shaft inserted into the receiving hole of the wheel frame via the support frame makes the overall weight of the wheel frame unsuitable for Children and increase the risk of tilting around the longitudinal axis of the shoe. Therefore, the present invention faces the problem of designing the previously described skate type for children in this way, on the one hand, it can reduce the weight of the wheel frame, and on the other hand On the one hand, the overall weight can be reduced. [Summary of the invention] The present invention solves this problem by forming a 200306223 body from a plastic molded body. The wheel frame includes a support receiving hole for receiving a roller bearing. The roller bearing is used to rotatably support the two Axles. Because of the influence of this method, instead of providing a separate support frame for the wheel axle, the wheel axle system is directly supported in the support receiving hole of the wheel frame via a roller bearing. It can be determined that it is a lower The overall weight is determined solely by the diameter of the roller. In addition, because children's roller skates have less roads, the wheel frame can be formed of a one-piece plastic body, which is lighter in weight than a metal wheel frame. In addition, since the two wheel shafts are rotatably supported in the support receiving holes of the wheel frame, other roller bearings needed to support the wheel on the wheel shaft can be omitted, so compared with the traditional For wheel frames, the number of roller bearings required can be halved. This means that further weight savings can be achieved and, in addition, the design is simplified. The formed body forming the wheel frame can be designed symmetrically with respect to a longitudinal central plane, which makes it possible to simplify the forming tool, especially concave cutting can be avoided. In order to ensure the simple and reliable fixing of the plastic wheel frame to the sole of the shoe body, the molded body of the wheel frame may include a receiving hole for a bolt and a slide-in guide for a nut. The slide-in guide The receiving hole is passed laterally. In this example, only the nut needs to be inserted into the slide-in guide. Because the nut is fixed in the slide-in guide in a torque-preventing manner, the bolt can be introduced into the receiving holes of the wheel frame through the sole in a simple manner, and bolted to the retaining holes. Among the nuts. [Embodiment] 200306223 According to the exemplary embodiment shown, a children's skate includes a children's shoe 1 with a sole 2 to which a wheel frame 3 is fastened securely. The wheel frame 3 is made of an integral molded body 4 made of plastic. The molded body 4 includes a support receiving hole 5 for receiving the front wheel shaft 6 and the rear wheel shaft 7. A roller bearing 8 for rotatably supporting the front wheel shaft 6 and the rear wheel shaft 7 is inserted into the support receiving hole 5, as reference can be obtained from FIG. 2. Therefore, the rollers 9 arranged in pairs on the front wheel shaft 6 and the rear wheel shaft 7 do not need to be rotatably supported on the roller shafts 6,7. In order to fix the molded body 4 to the sole 2 of the shoe 1, a bolt 10 is inserted into the sole 2 and is supported on the sole 2 via a washer 11 and extends through the sole 2 to the through hole 12. The molded body 4 forms a receiving hole 13 which is connected to the through hole 12 for the bolt 10 and the nut 14 to cooperate. These nuts 1 and 4 are fixed to the slide-in guide 15 in a torque-proof manner. The slide-in guide extends across the receiving hole 1 3, so the nuts 14 need only be introduced to the sole of the bolt 10 2 is pushed into the slide-in guide 15 before reaching the receiving hole 1 3. The tightening of the bolt 10 presses the molded body 4 against the sole 2 of the shoe 1 via the nut 14, so a torque preventing connection is established between the shoe 1 and the wheel frame 3. As can be obtained from Fig. 1, the wheel frame 3 may be provided with brake pads 16 bolted to the top of the molded body 4 of the wheel frame 3 in front and rear thereof. For this purpose, a slide-in guide 17 for a nut 18 may be provided in the molded body 4, wherein the nut extends through the slide-in guide 17 to a receiving hole 19 for a bolt 20. Area, as shown in Figure 1. Because the roller 9 is not rotatably supported on the rollers 200306223 6 and 7 via roller bearings, the rollers 6 and 7 are rotatably fixed to the wheel frame 3 by the roller bearings 8 Among the support receiving holes 5 of the molded body 4, a simple design results in that it satisfies that the roller bearing 8 is only used for the rollers 6 and 7, which brings additional weight reduction. In addition, because the molded body 4 of the wheel frame 3 is made of plastic, the overall weight of the skates can be kept relatively low. In addition, the support rollers 6 and 7 are not supported by a separate support frame, but are directly supported in the support receiving hole 5 of the molded body 4 via the roller bearing 8 so that the overall weight of the wheel frame 3 may be In other words, it is substantially determined only by the outside diameter of the roller 9. Therefore, the ground clearance of the shoe 1 can be advantageously minimized. [Brief description of the drawings] The drawings show the objects of the present invention by way of example.
