A wheel disc includes a hub located centrally within the wheel disc and defining a wheel axis. The wheel disc further includes an outer circumferential edge and a transition portion radially extending between the hub and the outer circumferential edge. The transition portion has a front surface and a rear surface such that the rear surface has a relatively smooth profile and the front surface has a plurality of concentric ring-shaped curvatures formed therein, thereby providing the transition portion with a variable thickness between the front and rear surfaces.

A wheel for vehicles is provided. The wheel has a rim of sheet metal having on its axially outer side an outer flange, an outer bead seat, an outer retaining hump, and a rim well connected to the outer bead seat through the outer retaining hump. The wheel has a disc of sheet metal having a cover part and a connection part axially protruding from the cover part. The connection part of the disc is fixed to a radially inner surface of the rim. At least one formation of additive material is formed on at least one of the rim and the disc, the at least one formation defining a steep thickness change with respect to a surrounding region of sheet metal.

Aluminum wheels include a rim and a disc having a mounting portion. The mounting portion includes an inner mounting face and an outer mounting face. The mounting portion also includes a coarse grain region and a fine grain region. The coarse grain region can be adjacent, and at least partially form, one of the inner mounting face or the outer mounting face. The coarse grain region includes aluminum alloy grains of a first average grain length that is greater than 1 mm. The fine grain region extends between the coarse grain region and the other of the inner mounting face or the outer mounting face. The fine grain region includes aluminum alloy grains of a second average grain length that is less than 0.5 mm.

The present invention explains a process for manufacturing tubeless vehicle wheel without welding using a hoop 100 having an outboard end 101, a centre region 102, an inboard end 103. The process includes spinning the outboard end 101 to obtain a disc region 202, spinning disc end 203 to obtain preform nave region 301. Forming the disc region 202 to obtain a disc profile 401 and a nave region 403, forming the centre region 102, inboard end 103 to obtain a straight rim profile 402. Spinning and forming outer end 405 of the straight rim profile 402 to obtain an outboard flange 502a and spinning the straight rim profile 402 to obtain a concave rim profile 601a with a preform inboard flange 602a. Spinning the concave rim profile 601a to obtain bead seats 701a, well region 703a and, forming the preform inboard flange 602a to obtain an inboard flange 704a.

A wheel for a non-motorized vehicle (e.g., a shopping cart) can include a housing assembly and a tread assembly. The housing assembly can be configured to sealingly house electronics or other components. The tread assembly can removably mate with the housing assembly such that the electronics or other components remain closed and/or sealed within the housing assembly when the tread assembly is mated or unmated with the housing assembly.

The invention refers to a furniture panel assembly (200, 200′ 200″, 200′″) comprising a furniture panel (300, 300′ 300″, 300′″) and a wheelhouse cassette (100, 100′, 100″, 100′″). The furniture panel (300, 300′ 300″, 300′″) has a slot (23) extending in a plane in parallel with and at least partly between the major surfaces of the furniture panel (300, 300′ 300″, 300′″) and the wheelhouse cassette (100, 100″, 100″, 100′″) is positioned in the slot (23). The wheelhouse cassette (100, 100′, 100″, 100′″) comprises a wheelhouse (1; 1′; 1″; 1′″) and a wheel (2) adapted to be inserted into and retainably engage the wheelhouse (1; 1′; 1″; 1′″).

A bicycle disc wheel comprises a first disc panel and a second disc panel. The first disc panel has a first side outer surface and a first side inner surface and the second disc panel has a second side outer surface and a second side inner surface. The first side outer surface radially extends from a first disc panel outer perimeter to a center opening and the second side outer surface radially extends from a second disc panel outer perimeter to the center opening. The second side inner surface faces the first side inner surface. A brace is coupled to the first side inner surface and the second side inner surface that provide radial and axial structural support to the disc panels.

A manufacturing method for a wheel disc, includes forming a flange portion, wherein the flange portion is formed such that an inner mold and an outer mold having a cylindrical inner surface with a first inside radius larger than the first outside radius and placed above the inner mold coaxially to the inner mold are brought close relative to each other in an axial direction by one stroke so that the outer edge of the disc material is bent downward, and the cylindrical inner surface of the outer mold is provided with recessed portions hollowed outwardly in a wheel radial direction, the recessed portions being formed in ranges corresponding to the window portions in the wheel circumferential direction and in a range from a middle position to a bottom end in the wheel axial direction.
