What the claims cover, in plain language

Claim 1 defines a bag comprising a body, a hand ring, and a support assembly. The assembly includes a support plate, a bracket, and a flip plate that form a triangle. Key features include:

  • An embedding groove on the support plate where the bracket slides.
  • Evenly distributed locking slots within that groove to adjust the angle between the support plate and flip plate.
  • A snap block and snap hole system to keep the plates flat when folded.
  • Sliding rails and sliders that allow the entire assembly to move in and out of the bag’s accommodation groove.

Claim 2 adds a rotatable clip strip on the side of the bag to prevent the support assembly from falling out when stored.

Claim 3 specifies that the support assembly is detachable from the bag body. It further describes cooling fans embedded in the support plate, connected via USB interfaces, and a mobile power supply (battery bank) included in the design to drive these fans.

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 due to non-payment of fees. Therefore, it no longer restricts anyone in China, and it never restricted production or sales in the United States or other countries because no foreign counterparts were filed.

Two points to settle early:

  • Other patents may exist. Laptop stands and convertible bags are a crowded field. While this specific triangular sliding mechanism appears unique in this document, broader patents covering “bag-with-stand” concepts or specific hinge mechanisms held by major accessory brands may apply. A freedom-to-operate (FTO) review is recommended before tooling.
  • Electronic Components. Claim 3 introduces electrical elements (fans, USB, battery). Manufacturing a version with these features triggers strict safety regulations regarding lithium batteries and electrical components that do not apply to the purely mechanical versions.

Customization and manufacturing

What can be customized

AreaOptions
MaterialNylon, polyester, leatherette, or TPU for the bag body; ABS, PC, or aluminum for the stand parts.
Stand SizeWidth and depth of the support plate to fit 13-inch, 14-inch, or 15.6-inch laptops.
Angle RangeNumber of locking slots determines the granularity of adjustment (e.g., every 5 degrees vs. every 10 degrees).
ElectronicsVersion A: Mechanical only. Version B: With cooling fans. Version C: With fans + integrated battery/power bank.
Color/FinishInjection mold colors, anodized finishes for metal brackets, custom logo placement on the hand ring or plate.

Things to plan for (US market)

  • UL 2056 / IEC 62368: Required if the design includes a power bank or mains-connected electronics. Lithium-ion batteries must comply with UN 38.3 for transport.
  • FCC Part 15: Applies if any wireless charging or Bluetooth modules are added (though the patent mentions USB wired connections, FCC certification is needed for any electronic emissions).
  • California Prop 65: Warning labels may be required for certain plastics, leathers, or brass fittings used in zippers and buckles.
  • ASTM D5866: Standard test methods for evaluating the durability of backpack straps and handles, relevant for the hand ring attachment points.

How a project runs

  1. Inquiry - Define size, material, and whether electronics (fans/battery) are included.
  2. Design - CAD modeling of the triangular mechanism, tolerance fitting for the sliding slots, and electrical layout if applicable.
  3. Prototype - 3D printed or CNC machined stand parts sewn into sample bags. Test deployment cycles and angle stability.
  4. Certification - Battery safety testing (if applicable), drop tests, and cycle life tests for the sliding rails.
  5. Production - Injection molding for plastic parts, cutting/sewing for the bag, assembly of the stand into the groove, final QC.

Quantities & timeline

Injection molds for the support plate, bracket, and flip plate take 4-6 weeks. Fabrication of the bag body depends on complexity but typically takes 2-3 weeks after pattern approval. Electrical components require sourcing lead times. Send us your target size, material preference, electronic requirements, quantity and target price and we will reply with options.
