What the claims cover, in plain language
Claim 1 defines an integrated multi-functional tool car comprising a rectangular body. The bottom front has symmetrically arranged locking universal caster wheels, and the bottom rear has symmetrically arranged one-way wheels. An open-type equipment holding tools drawer is provided at the bottom. On the sides relative to this drawer, there are detachable containing box a and detachable containing box b. Box b contains a solvent slop collecting vessel. Above the tool drawer is an adjuvant consumptive material storage drawer, and above that is a paint storage box. A work top is provided on the side of the paint storage box, with the paint box’s open top exposed. Rotary flip closing lids correspond to the open top. A solvent waste accommodating groove is at the top rear of the paint box, connected to the slop vessel via a waste discharge pellet valve and row solvent flexible pipe. Protrusion baffle plates are symmetrically arranged on the front side of the paint box top, with a handrail between them. A rotary axle holds masking paper rolls, and a fixing axle below holds paper self-adhesive tape. Cutting blades are positioned between the baffles at the front. A gas source three-way interface is on the lateral wall of the baffle plate.
Claim 2 specifies that the adjuvant consumptive material storage drawer contains multiple little lattice compartments. Claim 3 notes that the back side of the paint storage box has a steam vent. Claim 4 details the gas source three-way interface having one import on the back side and two gas outlets on the front.
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. It does not restrict anyone in China or elsewhere. It has no US or other foreign counterpart.
Two points to settle early:
- Other patents may exist. While this specific configuration is free to use, general automotive tool carts and masking dispensers are common products. A freedom-to-operate (FTO) review is recommended to ensure no other active patents cover similar features like specific caster mechanisms or integrated air manifold designs.
- Material compatibility. The cart handles solvents and paints. Material selection for the tank, drawers, and seals must resist chemical degradation from automotive thinners and clear coats.
Customization and manufacturing
What can be customized
| Area | Options |
|---|---|
| Dimensions | Width and height adjusted to fit standard garage bay sizes. |
| Materials | Steel body for durability; stainless steel for solvent tanks; HDPE for liners. |
| Wheel Type | Replace one-way rear wheels with swivels if omnidirectional movement is preferred (though less stable). |
| Capacity | Size of the paint storage box and number of tool drawers. |
| Gas Interface | Quick-connect fittings compatible with US standard air lines (e.g., IH, ACME). |
| Finish | Powder coating colors to match brand identity or shop decor. |
Things to plan for (US market)
- OSHA Regulations: General industry standards apply for handling flammable liquids. The solvent waste system should comply with local fire codes regarding storage and disposal of hazardous materials.
- UL Listing: If any electrical components (like lights or fans) are added, they must meet UL standards. The base design is purely mechanical.
- Chemical Resistance Testing: Materials in contact with solvents must pass ASTM D543 resistance tests to prevent leaching or failure.
How a project runs
- Inquiry - Define required capacity, dimensions, and material preferences.
- Design - CAD modeling of the chassis, drawer layouts, and baffle structures.
- Prototype - Fabrication of sample units for ergonomic testing and chemical resistance checks.
- Pilot run - Small batch production to verify assembly processes and quality control.
- Production - Mass manufacturing with processes and materials selected for solvent resistance, followed by final assembly.
Quantities & timeline
Tooling for the sheet metal chassis and injection molds for the drawers and baffles will drive initial lead times. Assembly is straightforward but requires careful fitting of the axle and blade mechanisms. Send us your target dimensions, material specifications, quantity requirements, and desired finish options and we will reply with options.
