Abstract
Description
[Technical Field]
[0001] This invention relates to a device for running a model train within an interior frame, and more particularly to a low-cost, small-sized running device that utilizes a sprocket chain drive mechanism. [Background technology]
[0002] In the past, rails had to be installed to run a model train, which made the device larger and made it difficult to run it within a frame. While magnet-driven and guide rail systems exist, they are complex in structure and expensive.
[0003] To provide a device that can run a model train in the internal space of a frame using a simple mechanism.
[0004] This device includes a sprocket chain placed inside a picture frame, an arm member fixed to the chain, and a model vehicle attached to the end of the arm member. The chain is driven in a circular motion by a motor, and the arm member moves within the picture frame following the movement of the chain, thereby allowing the model vehicle to run within the picture frame.
[0005] This invention allows the model train to run in the limited space within the frame without the need for rails, and the structure is simple, compact, and low-cost.In addition, since it uses a frame, it has a high interior design and is useful as a decorative item. [Brief explanation of the drawings]
[0006] FIG. 1 is a perspective view showing the overall configuration of a sprocket chain, sprockets, and a model vehicle arranged within a frame.
[0007] Figure 2 is a side view (example of a streetcar) showing the relationship between the model vehicle, arm, and sprocket chain.
[0008] Figure 3 is a side view (example of a steam locomotive) showing the relationship between the model vehicle, arm, and sprocket chain.
[0009] Figure 4 is a detailed view showing the joint between the arm and the sprocket chain. DETAILED DESCRIPTION OF THE INVENTION
[0010] A motor-driven sprocket chain is placed inside the frame, an arm is attached to the chain, and a vehicle is fixed to the end of the arm. The vehicle travels inside the frame due to the circular drive of the sprocket chain. [Industrial Applicability]
[0011] This invention can be widely used as an interior toy, display item, or decorative item. [Explanation of symbols] 1. Picture Frame 2 sprocket chain 3 Arm 4 Model trains 5 motors 6 sprockets 7 Joint
Claims
[Claim 1] A model car running device comprising a sprocket chain arranged within a frame, an arm member fixed to the sprocket chain, and a model car attached to the tip of the arm member, wherein the arm member moves within the frame as the sprocket chain is driven in a circular motion by a motor, and the model car runs within the frame following this.
