What the claims cover, in plain language
Claim 1 - a rotating trampoline with a trampoline body, a rotating motor in its middle whose output shaft carries an inflatable swing arm.
Claim 2 - the body is hexagonal or octagonal. Claim 3 - the body has a central support frame and an outer support frame joined by upper and lower connecting rods. Claim 4 - elastic cloth between the upper rods. Claim 5 - the upper rods and central frame are covered by a soft protective layer. Claim 6 - the motor sits on top of or inside the central frame with its shaft above it.
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.
Two points to settle early:
- Other patents may exist. Rotating sweeper games are widely sold as inflatable party rentals, and trampoline court designs are patented by park equipment suppliers, so a freedom-to-operate (FTO) review of the combined trampoline and sweeper is advisable before production.
- Ride classification. Some US states treat motorized attractions as amusement rides needing permits and inspection; the classification is checked for each target state.
Customization and manufacturing
What can be customized
| Area | Options |
|---|---|
| Layout | Six or eight beds, overall diameter, bed size |
| Frame | Galvanized or powder-coated steel; in-ground or above-ground |
| Beds | Jump mat type and spring or bungee suspension |
| Arm | Length, height above the beds, PVC or TPU inflatable, colors |
| Drive | Gear motor, variable speed, auto-reverse on contact, emergency stop |
| Game | Timer, round speeds, lights and sound, scoreboard |
Things to plan for (US market)
- ASTM F2970 - design, manufacture, installation and operation of trampoline courts; trampoline parks and their insurers follow it.
- ASTM F2291 and F1193 - design and quality of amusement rides; relevant where a state classifies the motorized arm as a ride.
- ASTM F2374 - design and operation of inflatable amusement devices, for the inflatable arm and blower.
- State amusement ride laws - permits and inspections vary by state; the product file includes the data inspectors ask for.
- UL 508A / NFPA 70 - control panel and wiring for the motor, with emergency stop.
How a project runs
- Inquiry - site size, number of beds, indoor or outdoor and quantity.
- Design - frame, beds, motor mount, arm height and speed control.
- Prototype - a test unit for jump, contact and stop tests.
- Pilot run - documentation for insurers and state inspectors; installation manual.
- Production - frame fabrication, mat sewing, inflatable welding, controls and crating.
Quantities & timeline
The frame needs steel fabrication jigs and galvanizing or powder coating, the jumping beds and padding are sewn, the arm is welded PVC or TPU, and the drive uses a sourced gear motor with a custom control box. Safety documentation and testing take the most time. Send us your site plan, number of beds, indoor or outdoor use, quantity and target price and we will reply with options.
