Hammer with Integrated LED Lighting and Storage Compartment

Patent & Production

At a glance

What the claims cover, in plain language

Claim 1 defines a hammer comprising a handle and a tup (head). A lighting device is included, consisting of a lamp stand with a headlamp. The lamp stand has a vessel for a power supply and a control switch on its lateral wall. The peripheral surface of the lamp stand features a first screw thread near the headlamp and a second screw thread away from it. The handle’s end face has a mounting base with a threaded hole designed to connect with either the first or second screw thread.

Claims 2-9 add details such as a groove at the bottom of the threaded hole to house the headlamp shell, a storage chamber within the handle aligned with the threaded hole, a parcel tray fitting into this chamber, and an end cap with a connecting pole and gripper rings for retrieving the tray.

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 in China and has lapsed, so it no longer restricts anyone in China. The public record shows no US or other foreign counterpart.

Two points to settle early:

• Other patents may exist. Hand tools with integrated lights are a competitive field. While this specific utility model is expired, later foreign patents citing this document (such as EP3825082A1 held by Vision Devices GmbH) indicate ongoing innovation in illuminated tools. A freedom-to-operate (FTO) review is recommended to ensure no active US patents cover similar threading mechanisms or internal storage configurations in hammers.
• Electrical Safety. Since the design includes a battery and electrical circuit, US market entry requires adherence to specific safety standards for consumer products containing batteries.

Customization and manufacturing

What can be customized

Things to plan for (US market)

• CPSC Regulations: General safety requirements for household tools.
• Battery Compliance: UN 38.3 for shipping lithium batteries (if applicable); FDA 21 CFR if marketed for food-related industries (unlikely but check labeling).
• FCC Part 15: If the lighting module uses wireless charging or any radio frequency components, FCC certification is needed. Standard LED circuits typically do not require FCC ID unless they emit significant interference.
• OSHA Standards: For industrial use, ensuring the tool does not present pinch hazards or electrical shock risks.

How a project runs

1. Inquiry - Define target load class, light specs, and storage volume.
2. Design - Finalize handle geometry, thread interface, and tray mechanism.
3. Prototype - 3D print handle and machining test parts; assemble functional sample.
4. Pilot Run - Test durability of threads and drop tests for the lighting module.
5. Production - Die-cast or forge heads, injection mold lamp stands, assemble.

Quantities & timeline

Tooling costs are driven by the complexity of the handle’s internal cavity and the precision required for the screw threads. Injection molds for the lamp stand and tray are necessary. Assembly involves inserting electronics and testing each unit. Send us your specifications for light output, handle material, and estimated quantity and we will reply with options.

Production notes

Tooling and process

The handle likely requires die-cast aluminum or forged steel, followed by machining to create the internal storage chamber and precise threads. The lamp stand is typically glass-filled nylon injection molding to resist impact. Heat treatment may be applied to the hammer head for hardness.

Cost drivers

Material selection (especially if using high-grade alloys for the handle) and the number of stamping dies or injection molds typically drive initial costs. Cutting edge machining for the threads adds time. Surface finish quality also impacts price.

Prototyping path

Prototyping typically starts with a 3D-printed handle to verify ergonomics and thread fit. Use machined or off-the-shelf blades for the head. Create heat-treatment trial coupons to validate strength before committing to full tooling.

What we would change before tooling

We would refine the thread engagement tolerance to prevent stripping under torque. The snap-fit or press-fit pins for the tray mechanism should be tested for retention strength. Ensuring proper strain relief for any internal wiring in the lamp stand is critical.

Common failure points

Edge hardness below spec can lead to chipping. Pivot pin wear (if articulated parts are used) or spring fatigue in the gripper rings could cause loss of function. Thread engagement issues may result in the light detaching during use. Handle creep under heavy impact loads is a structural risk to monitor.

Frequently asked questions

How does the light attach to the hammer?

The lamp stand has two sets of threads. You screw it into the mounting base at the end of the handle. One thread orientation makes the light face outward for working; the other makes it face inward to protect the lens when stored.

Can I remove the light completely?

Yes. The lighting device is modular. Unscrewing it entirely leaves you with a standard hammer. The handle remains usable without the light attachment.

What fits in the storage chamber?

The internal tray is designed for small fasteners like nails, screws, drill bits, or anchors. The exact capacity depends on the final design dimensions, which are confirmed on prototypes.

Is the hammer balanced with the light attached?

Adding the light shifts the center of gravity slightly toward the handle end. Manufacturers typically adjust the head weight or handle thickness to maintain a comfortable swing feel.

Does it use rechargeable batteries?

The patent mentions a power supply in a vessel, preferably a dry cell. Custom versions can be designed with rechargeable lithium-ion cells and USB charging ports, depending on the model.

Is it safe to use in wet conditions?

Standard models may not be waterproof. If you need to work in rain or damp areas, look for IP-rated seals on the switch and threads, which can be specified in custom orders.

Can this design be made and sold in the US?

The patent was filed in China and has lapsed, and the public record shows no US counterpart, so it does not restrict the design in the US. However, illuminated tools are a crowded field, so we recommend a freedom-to-operate check to ensure no other active US patents cover specific features like the dual-thread orientation or internal tray mechanism.

Are you affiliated with the patent owner?

No. IP2M is an independent design and manufacturing service working from the public patent document.
