Patent CN108635881B

Updated November 2, 2026

Indoor Toy Tent with Adjustable Basketball Hoop

Standard indoor tents often lack interactive elements or have unstable attachments for sports gear. This patent describes a tent where the basketball hoop is secured by adjustable straps with elastic buckles, allowing height customization for growing children without complex hardware. The integration of functional accessories like activated carbon pockets and anti-slip bases turns a simple shelter into a dedicated activity zone. The conical top with a chimney-like vent and gauze-covered windows further enhance usability for indoor settings.

The problem

Children’s indoor play tents typically offer shelter but lack integrated, adjustable sports equipment. Attaching a basketball hoop to a soft fabric structure is challenging; fixed attachments limit use as children grow, while loose attachments shake during play, causing frustration and potential instability. Furthermore, enclosed indoor spaces can suffer from poor air circulation, and standard tent fabrics do not address common household pests like mosquitoes, limiting the tent’s utility as a comfortable, long-term play zone.

The solution

The patent describes a tent cloth comprising a top cloth, side cloth, and bottom cloth sewn together, supported by a frame. The side cloth features a door and window. On the outer surface, a shooting assembly is mounted. This assembly uses two symmetrically arranged fixing belts attached to the side cloth. Each belt has three or more mounting openings. A basket frame is connected to fixing rods and ropes. These rods and ropes terminate in elastic buckles that clip into the chosen mounting opening on the belts. By selecting different openings, the height of the basket is adjusted. The elastic section of the buckle compresses into the opening and rebounds to lock it, ensuring stability. Internally, the tent includes traction ropes holding porous covers with activated carbon balls for air purification, and anti-mosquito medicine bags with nano-capsule films. An anti-slip layer is applied to the base fabric.

Operating steps

  1. Setup: Unfold the tent using the support frame. Ensure the anti-slip base contacts the floor.
  2. Hoop Adjustment: Determine the child’s height. Select the appropriate mounting opening on the fixing belts.
  3. Attachment: Clip the elastic buckles of the fixing rods and ropes into the selected openings. The elastic rod compresses and then locks into place.
  4. Accessories: Place activated carbon balls inside the porous protective covers hanging from traction ropes. Insert mosquito repellent films into the side cloth bags.
  5. Play: Children enter through the door. They shoot balls at the basket. The gauze windows allow ventilation while keeping insects out.

Applications

Home Living Rooms

Fits easily in corners of living rooms, providing a designated area for active play without occupying excessive space. The anti-slip base protects hardwood or tile floors from scratches and prevents the tent from sliding during vigorous activity.

Daycare Centers

Offers a controlled environment for motor skill development. The adjustable hoop allows teachers to set difficulty levels appropriate for different age groups, encouraging participation among children of varying heights.

Bedroom Play Zones

Creates a private, immersive space for children. The integrated air purification pockets help maintain fresh air quality in smaller, enclosed bedroom areas, while the mosquito repellent feature adds comfort during summer months when windows may be open.

Indoor Event Spaces

Suitable for birthday parties or community events held indoors. The sturdy fixing mechanism ensures the hoop remains stable despite frequent use by multiple children, reducing maintenance needs compared to simpler attachment methods.

Where it is less suitable

  • Outdoor Use: Designed specifically for indoor environments; materials may not withstand rain or UV exposure.
  • Heavy Duty Training: Intended for casual play and learning, not professional athletic training requiring rigid, heavy-duty hoops.
  • Large Groups: The single-hoop configuration limits simultaneous active players, making it less ideal for large team games.

Frequently asked questions

Is the basketball hoop height adjustable?

Yes. The patent describes fixing belts with three or more mounting openings. You change the height by clipping the elastic buckles into different openings, allowing the hoop to grow with the child.

Are the activated carbon balls safe for children?

The patent specifies that the activated carbon is contained within porous protective covers suspended by traction ropes. For US sales, these components must comply with ASTM F963 and CPSIA regulations to ensure they are not accessible as small parts if the tent is damaged.

Does the tent really repel mosquitoes?

The design includes breathable non-woven bags containing films wrapped with nano-scale microcapsules of pyrethroid compounds. Effectiveness depends on the concentration and longevity of the active ingredient used in the final production.

Can I remove the extra features?

Yes. The air purification pockets and mosquito bags are separate components attached to the inner cloth. They can be omitted or replaced with different accessories depending on the market demand.

What is the anti-slip layer made of?

The patent mentions an anti-slip layer on the base fabric but does not specify the exact material. Common choices include silicone dots or rubberized backing, which must meet flammability standards for toys.

How stable is the hoop during play?

The hoop is secured by two fixing rods and two fixing ropes using elastic buckles. The patent states this arrangement strengthens the connection and prevents shaking, provided the buckles are correctly clipped into the mounting openings.

Can this design be made and sold in the US?

The patent is in force in China only. There is no US patent blocking this design. However, you must ensure the product meets US safety standards (ASTM F963, CPSIA) and conduct a freedom-to-operate check to avoid infringing on other existing US patents in the toy tent category.
