What the claims cover, in plain language
Claim 1 - a connecting seat with a body, a connector on top for a camera or phone clamp, and at the bottom a rotating support leg inside a storage slot, pivoted to the slot’s side walls. The bottom of the body is flat with dovetail edges for a quick-release clamp, and/or the leg’s end has a screw hole for a quick-release plate.
Claim 2 - the body is two parallel legs with the slot between them. Claim 3 - triangular feet, wider than the legs, whose sloping faces form the dovetail; the support leg is pivoted in the feet. Claims 4-5 - a joint housing on top in which the connector turns and locks: base with arc slot, two clamp pads, cover and locking knob clamping a ball connector. Claims 6-7 - the rotation of the connector and of the support leg. Claim 8 - a phone clip made of the connecting seat plus a clamp.
This is a simplified reading for orientation only. The legal scope is defined by the exact claim wording in the official Chinese documents, and the claims of the invention patent CN106989257B may differ from the utility model.
What this means for US production
These patents were filed only in China. The invention patent CN106989257B is in force in China, so making or selling this design in China would need the owner’s permission while it lasts (at most until 2037-05-23). There is no US or other foreign counterpart, so these patents do not restrict the design outside China.
Before production, keep in mind:
- Other patents may exist. Phone mounts, tripod heads and quick-release systems are crowded categories with many US utility and design patents. Use your own styling and have a freedom-to-operate (FTO) search done by a US patent attorney before volume production.
- Trademarks. “Arca-Swiss” is a trademark; describe compatibility in generic terms (“Arca-type quick-release clamp”) unless you have permission.
Customization and manufacturing
What can be customized
| Area | Options |
|---|---|
| Body | CNC-machined or die-cast aluminum; glass-filled nylon for a budget version |
| Finish | Anodized colors, sandblasted or matte black; laser-engraved logo |
| Top | Ball joint with 1/4"-20 screw; cold-shoe add-on - to be confirmed in design |
| Base | Dovetail width matched to common quick-release clamps; 1/4"-20 hole |
| Phone clamp | Spring clamp size range, rubber pads, landscape/portrait rotation |
| Kits | Bundles with mini tripod, selfie stick or carry pouch |
Things to plan for (US market)
- Thread standard - US photo gear uses 1/4"-20 UNC threads; specify these instead of metric.
- Load rating - state a tested maximum load and do not overstate it in listings.
- Materials - check coatings and rubber pads for California Proposition 65 substances.
- Packaging claims - “compatible with” claims for named phone or tripod brands need care; use generic sizes.
How a project runs
- Inquiry - material, finish, phone clamp range and quantity.
- Design - dovetail and thread details, knob and leg friction, styling.
- Prototype - machined samples for fit and stability tests.
- Pilot run - small batch to check tolerances and finish.
- Production - volume production, packaging and shipping.
Quantities & timeline
CNC machining suits small first orders; die-casting or molding needs tooling and suits larger runs. Send us your material, finish, quantity and target price and we will reply with options.
