What the claims cover, in plain language
Claim 1 - a skateboard truck with a baseplate for the deck, a pin that can turn in a hole in the baseplate, a clamp pivoted to the lower end of the pin, an axle fixed in the clamp (axle and clamp can rotate relative to the pin and baseplate), and an elastic sleeve on the pin between the clamp and the baseplate that limits the relative rotation of pin and clamp.
Claim 2 - the clamp is an open ring with two ears; the pin’s lower end sits between the ears and a cross pin passes through holes in both.
Claims 3-10 - further features from the description: vertical slotted holes so the cross pin can move up and down against the sleeve, a groove in the axle for the clamp, a gasket with a turned-down edge, bearings on the pin, a square head in a larger square pocket to limit the turn, return springs or a metal leaf in the pocket, and a two-piece threaded pin.
This is a simplified reading for orientation only. The legal scope is defined by the exact claim wording in the official Chinese document.
What this means for US production
This patent was filed only in China and has lapsed, so it no longer restricts anyone in China either. It has no US or other foreign counterpart.
Before production, keep in mind:
- Other patents may exist. Skateboard, surfskate and cruiser trucks are an active patent area in the US. Have a freedom-to-operate (FTO) search done by a US patent attorney before volume production.
- Engineering. The patent gives no dimensions or materials; pin diameter, sleeve hardness and turn limits are set and load-tested in development.
Customization and manufacturing
What can be customized
| Area | Options |
|---|---|
| Width | Axle width to suit the deck - to be confirmed in design |
| Materials | Steel or aluminum baseplate and clamp; steel pin and axle |
| Rubber sleeve | Hardness (soft for kids, firmer for adults), urethane or rubber |
| Turn limit | Size of the square pocket; optional return springs |
| Finish | Powder coat, anodizing, colors |
| Supply | Trucks only, or complete boards with wheels and bearings |
Things to plan for (US market)
- Skateboard standard - ASTM F2847 (Standard Practice for Reporting Test Results for Skateboards) is commonly used for strength and durability testing of complete boards.
- Children’s products - boards for children 12 and under need CPSIA lead and phthalate testing, tracking labels and a Children’s Product Certificate; toys for under-14s may also fall under ASTM F963.
- Warnings - recommend helmets and protective gear in labeling and instructions.
How a project runs
- Inquiry - board type, rider weight, width and quantity.
- Design - pin, clamp and sleeve sizing; turn limits.
- Prototype - samples for ride, load and fatigue tests.
- Pilot run - small batch with third-party testing.
- Production - volume production, packaging and shipping.
Quantities & timeline
Stamped or machined parts need simple tooling, and the sleeve needs a mold. Send us your board type, rider weight range, quantity and target price and we will reply with options.
