The shaft has a first handle section, a second handle section, and a central section, and also has a shaft length greater than the core length. The handles are removably connected to the handle sections of the shaft. Preferably, the handle sections of the rolling pin shaft have locking features, and the handles have catches that releasably engage the locking features. The rolling surface is made from, or contains, thermoplastic elastomer. In at least some embodiments, the rolling surface can be a sleeve that slides onto the outer surface of the core and is secured to the ends of the core by end caps.01-15-2009
20090105058LIGHTWEIGHT, SMALL DIAMETER PAINT ROLLER - A novel paint roller “cage” having improved tracking and ease of use is adapted for receiving different length axle shafts of various sizes of paint roller frames. An outer tubular support, upon which a paint roller cover or other paint absorbing material may be mounted, contains a pair of support bearings secured at either end of an inner tubular chassis, with one support bearing at a first end of the outer tubular support, and the other support bearing at approximately its mid point. The two support bearings are connected by an inner tubular chassis, which both maintains the two bearings at a desired axial spacing and also holds the walls and radial bearing surfaces of a bushing chamber that is integrally molded with each support bearing in proper position about a tubular bushing that is adapted to be frictionally secured to the axle shaft. In one embodiment, the outer tubular support has a diameter of about 1″ and a length of about 9″, and can be used with both 6.5″ and 9″ roller frames. The nominal axial clearance between the tubular bushing and the adjacent radial bearing surfaces of the bushing chamber is less than about 0.005″.04-23-2009
20090247379PAINT ROLLER - A paint roller assembly providing a friction hinge for a swiveling connection between the handle and the paint applicator and a clip for locking the tubular paint applicator against unwanted axial displacement during the use.10-01-2009
492004000 WITH INFLATABLE CHAMBER 2
20100113237INFLATABLE SHAFT - An inflatable shaft mainly includes an elastic rubbery sleeve mounted around the outer wall of plural outer pressing boards and able to expand outward to cover gaps formed among the outer pressing boards while inflating the inflatable shaft, so as to provide a seamless exterior surface for the air expanding shaft to be directly wound with a stuff without having the stuff sunk or clamped. And, the rubbery sleeve can shrink inward together with the outer pressing boards while deflating the inflatable shaft, forming a space between the rubbery sleeve and the stuff to enable the stuff easily separated from the deflated shaft. Thus, the stuff can be smoothly wound around the inflatable shaft inflated without using an additional tube, not only lowering manufacturing cost but also amiable to environment.05-06-2010
