Track toys for easy-to-remove toy cars

Abstract

A track toy for easy-to-access toy cars includes a track body and a toy car body. The track body comprises multiple basic track units, each with a guide rail and two slots. The toy car body has wheels that can move along the guide rails and a power mechanism that drives the wheels to rotate. The toy car body also has two engaging connectors mounted on it. The lower end of each connector has an outwardly protruding engaging portion that matches the slot. The engaging portion has an upper outer side that slopes outward from top to bottom and a lower outer side that slopes outward from bottom to top, or an annular side or a spherical cap surface that slopes inward from the inside to the center. With this track toy, the toy car can be directly accessed and placed at any position on the track without disassembling the continuous track.

Claims

1. A track toy for easy-to-access toy cars, comprising a track body and a toy car body, the track body comprising multiple basic track units, each basic track unit having a guide rail arranged along its length and two slots arranged on the left and right; the toy car body having wheels that can move along the guide rails and a power mechanism that can drive the wheels to rotate; characterized in that: the lower end of the toy car body has a through hole, and the toy car body also has two engaging connectors, the engaging connectors being installed on the toy car body, and the lower part of the engaging connectors extending out of the through hole from the lower end of the toy car body; the lower end of the engaging connectors having an outwardly protruding engaging portion, the engaging portion matching the slots; the engaging portion having an upper outer side inclined from top to bottom and an lower outer side inclined from bottom to top, or the engaging portion having an annular side or a spherical crown surface inclined from the inside to the outside towards the middle.

2. The track toy with an easily accessible toy car as described in claim 1, wherein, The engaging part is a protrusion, which is fixedly installed at the lower end of the engaging connector.

3. The track toy with an easily accessible toy car as described in claim 2, wherein, The protrusion is in the shape of a triangular prism, frustum, cone, sphere, spherical notch, or hemisphere. When the protrusion is triangular prism, the upper outer surface of the protrusion is inclined outward from top to bottom, and the lower outer surface of the protrusion is inclined outward from bottom to top. When the protrusion is frustum or cone, the side surface of the protrusion is an annular side surface that is inclined from the inside to the outside towards the middle. When the protrusion is spherical, spherical notch, or hemisphere, the protrusion has a spherical cap surface that is inclined from the inside to the outside towards the middle.

4. The track toy with an easily accessible toy car as described in claim 1, wherein, The engaging part is a roller, which is rotatably mounted on the lower end of the engaging connector.

5. The track toy with an easily accessible toy car as described in claim 4, wherein, The roller is shaped like a frustum, a cone, a sphere, a spherical notch, or a hemisphere. When the roller is shaped like a frustum or a cone, the side of the roller is an annular side that slopes from the inside out towards the middle. When the roller is shaped like a sphere, a spherical notch, or a hemisphere, the roller has a spherical cap that slopes from the inside out towards the middle.

6. A track toy with an easily accessible toy car as described in claim 1 or 4, wherein, Two slots are respectively provided on both sides of the guide rail. A part of the walking wheel extends out of the through hole and is located between the lower parts of the two engaging connectors. The engaging connectors are hinged to the toy car body, and the toy car body also includes a return spring that allows the lower end of the engaging connector to swing outward. A pivot is provided in the middle of the engaging connector, and the engaging connector can be swung and mounted on the toy car body through the pivot. The upper part of the engaging connector is a first vertical part extending upward from the rotation axis, and the lower part of the engaging connector includes an inclined part extending downward from the rotation axis and a second vertical part extending downward from the lower end of the inclined part. The left and right edges of the through hole are respectively provided with inwardly extending limiting blocks, and the inclined part contacts the limiting blocks. The engaging part protrudes outward from the outer side of the lower end of the second vertical part, and a gap is formed between the upper end of the engaging part and the lower end of the inclined part, and the gap matches the thickness of the slot wall.

7. A track toy with an easily accessible toy car as described in claim 1 or 4, wherein, The guide rail is a rack, and the traveling wheel is a gear that matches the rack.

8. The track toy with an easily accessible toy car as described in claim 7, wherein, The power mechanism includes a power source, a motor, and a gear set. The power source is electrically connected to the motor. The output shaft of the motor is connected to the first gear of the gear set. A portion of the last gear of the gear set extends out of the toy car body and meshes with the guide rail. The last gear of the gear set constitutes the walking wheel.

9. A track toy with an easily accessible toy car as described in claim 1 or 4, wherein, The traveling wheel is a friction wheel that mates with the upper surface of the guide rail.

10. The track toy with an easily accessible toy car as described in claim 9, wherein, The upper surface of the guide rail is rough; the upper surface of the guide rail is rough.
