What the claims cover, in plain language
Claim 1 - an adjustable guide rail with a rail body and an angle bracket mounted inside the cabinet. An adjusting plate is fixed under the lower rail and has adjusting holes; the bracket has matching screw holes; screws pass through both to fix them together.
Claim 2 - a mounting groove on the bracket and a matching protrusion on the plate for quick positioning. Claim 3 - an alignment line on the plate edge and adjustment graduations on the bracket.
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. It is still in force in China, so making or selling this design in China would need the owner’s permission while it lasts (at most until 2028-06-15). It has no US or other foreign counterpart and does not restrict the design outside China.
Before production, keep in mind:
- Other patents may exist. Drawer slides and pull-out organizers are made by large hardware companies with many US patents. Use your own styling and have a freedom-to-operate (FTO) search done by a US patent attorney before volume production.
Customization and manufacturing
What can be customized
| Area | Options |
|---|---|
| Rail length | Common cabinet depths - to be confirmed in design |
| Adjustment range | Slot length for the cabinet widths you want to cover |
| Load rating | Ball-bearing or roller rails, steel gauge |
| Finish | Zinc, black or white coating |
| Kit | Rails alone, or complete basket kits |
| Packaging | Retail box with template and instructions |
Things to plan for (US market)
- Load and cycle testing - state the rated load per pair and test opening cycles.
- Installation - clear instructions and a template; the graduations should be easy to read.
- Labels - country of origin on the packaging; check coatings against California Proposition 65.
How a project runs
- Inquiry - cabinet sizes to cover, rail length, load and quantity.
- Design - plate, slot and bracket dimensions; scale layout.
- Prototype - samples for load, cycle and adjustment tests.
- Pilot run - small batch to check stamping and coating.
- Production - volume production, packaging and shipping.
Quantities & timeline
Rails, plates and brackets are stamped steel parts; stamping dies are the main tooling. Send us your cabinet sizes, load, quantity and target price and we will reply with options.
