Caulking gun with attachable camera and phone display

A hand-held caulking gun with an adjustable phone display mount on the trigger housing and an adjustable camera at the rear. The camera links to a handheld device (for example a smartphone) and the user places the phone on the display holder to view the work surface at a distance while dispensing caulk. Intended users are tradespeople or DIYers who need to see hard-to-reach joints without repositioning a ladder or bending repeatedly.

(57) What the patent covered

This write-up was generated by AI from the patent's text and may contain mistakes, so check it against the original patent before relying on it.

The main independent claim covers a caulking gun having: a cartridge holder spanning distal to proximal ends to receive a caulk cartridge; a trigger mechanism at the distal end that pushes a push-rod; a display holder adjustably attached to the top of the trigger mechanism; and a camera adjustably attached to the proximal end with communication means to connect to a handheld device so the handheld device on the display holder shows a view of the surface while caulking.

Distinguishing feature: The combination of an adjustable phone display holder mounted on the trigger housing together with an adjustable rear-mounted camera that streams to the handheld device while the gun dispenses caulk.

Novelty 3/5. Attaching accessories (lights, cameras) to hand tools was known; the patent claimed the specific arrangement of an adjustable display holder on the trigger housing plus a camera at the gun rear for remote viewing, a practical improvement over ordinary caulking guns.

Manufacturing

Injection-molded plastic body components, stamped or machined metal drive rod and trigger parts, off-the-shelf camera module wired or wireless, simple fasteners and manual assembly.

Materials: Injection-molded ABS or polypropylene housing, stamped or machined steel push-rod/drive components, rubber or silicone phone pads/clamps, plastic filmed camera housing, common CMOS camera module.

Manufacturability 4/5. Several molded or stamped parts and an off-the-shelf camera module; requires assembly of mechanical drive, adjustable mountings and basic electronics but no precision optics or firmware development if using a standard camera module.

Market demand

No comparable product was found on sale. No US online listings found for a caulking gun with an attachable camera and phone display as described; the concept appears not to be marketed as a ready-made product today.

Demand check by web search, week of Oct 12, 2026. Listings change frequently.

Buyers: Professional tradespeople and DIY homeowners working on high or awkward joints.

Before manufacturing

No related continuation or divisional patents in force were found. Design patents, trademarks and unrelated patents may still cover the product.

Practical risks include the need for secure phone mounting and camera connection reliability; patent has lapsed so no active protection, but design may face crowded accessory market and regulatory/safety expectations for tool attachments.

About 1.5% of lapsed patents are later revived by their owners. This page is a research lead, not legal advice. Obtain a freedom-to-operate opinion before manufacturing.

Claim 1, as granted

1. An expandable caulking gun having a distal end and a proximal end which receive a caulking cartridge with a caulking material comprises of: a) a cartridge-holder extended from said distal end to said proximal end to receive said caulking cartridge; b) a trigger mechanism at said distal end to push a push-rod; c) a display holder adjustably attached to a top portion of said trigger mechanism; d) a camera adjustably attached to said proximal end and having a communication means to connect to a handheld device; whereby a user places said handheld device on said display holder and connects said camera to said handheld device to observe a surface or grooves located a distance from said user while applying said caulking material.
