What the claims cover, in plain language
Claim 1 - An indoor toy tent comprising tent cloth (top, side, bottom) and a support frame. The side cloth has a door and window. A shooting assembly is on the outer surface, consisting of two symmetrical fixing belts with 3+ mounting openings, a basket frame, fixing rods, and fixing ropes. The rods and ropes connect to the basket and end in fixing buckles. The buckles clip into the mounting openings. The buckle has an elastic section (upper/lower parts oblique to a central rod) and a non-elastic section. Air purification components (porous covers with activated carbon balls) hang from traction ropes inside. An anti-slip layer is on the base fabric. Mosquito-repellent bags with nano-capsule films are on the inner side cloth. Windows have gauze layers secured by lacing.
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 is currently in force. Making or selling this specific design in China requires the owner’s permission. It has no US counterpart.
Two points to settle early:
- Other patents may exist. Children’s play tents and basketball hoops are widely patented fields. While this specific combination of elastic buckles and air purification pockets appears unique to this filing, prior art in adjustable hoop mechanisms and tent accessories must be checked. A freedom-to-operate (FTO) review is recommended before tooling. Note: WO2020082511A1 cites this patent, indicating international interest in this technology.
- Material Safety. The inclusion of nano-capsules and activated carbon requires careful sourcing of compliant materials to meet US toy safety standards regarding chemical substances.
Customization and manufacturing
What can be customized
| Area | Options |
|---|---|
| Dimensions | Base size, height, and hoop position range |
| Fabric | Color, pattern, and material type (polyester, nylon) |
| Hoop Mechanism | Number of mounting openings per belt; buckle tension |
| Accessories | Inclusion/removal of air purification pockets and mosquito bags |
| Windows/Doors | Size of gauze mesh; zipper vs. velcro closure |
| Base | Thickness of anti-slip layer; shape (square, circular) |
Things to plan for (US market)
- ASTM F963 - Standard Consumer Safety Specification for Toy Products. Critical for small parts, choking hazards, and flammability.
- CPSIA - Lead and phthalate limits for accessible plastic and metal components.
- 16 CFR 1501 - Small parts testing for toys intended for children under 3 years.
- Labeling - Age grading and warning labels required by CPSC.
- Chemical Compliance - Nano-capsules and activated carbon must be verified for safe encapsulation to prevent ingestion or inhalation risks.
How a project runs
- Inquiry - Define target age group, dimensions, and desired features.
- Design - Finalize tent geometry, buckle mechanics, and accessory placement.
- Prototype - Create samples for fit, function, and safety testing.
- Pilot Run - Conduct ASTM F963 and CPSIA tests; verify durability of buckles.
- Production - Sew tent panels, mold buckles, assemble frames, pack accessories.
Quantities & timeline
Tooling for injection-molded elastic buckles takes 4-6 weeks. Fabric cutting and sewing lines require setup for each colorway. Safety certification testing typically adds 2-4 weeks. Send us your dimensions, age grade, feature list, quantity and target price and we will reply with options.
