Movable robot

A movable robot includes a main body unit, and at least three wheel units connected with the main body unit. The wheel units have respective contact portions for contact with a floor surface. The contact portions are rotatable about respective axes. The main body unit moves along the floor surface as the contact portions rotate. Lines projected onto the floor surface and originating from the axes of rotation of the contact portions are spaced at substantially equal angular intervals. At most two of the axes are on a common plane. Each of the wheel units includes a motor base, a rotation drive motor supported on the motor base, a casing being rotatable relative to the motor base about related one of the axes and having related one of the contact portions, and a device for transmitting a rotational force generated by the rotation drive motor to the casing.

Rotatable wheel assembly for coolers

The rotatable wheel assembly includes an axle and wheels. Mounting arms with mounting pins or L-shaped rods are coupled to the axle and may include end caps covering portions of the mounting pin or rod. The mounting pin or end cap is inserted into a receptacle on opposing sides of a cooler. Alternatively, the mounting arms may have an eyelet that may be rotatably coupled to a mounting stud on each side of the cooler. The assembly may be placed in a resting or rolling position along the cooler body. In the resting position, the assembly rests or snaps into a groove along the side of the cooler and out of contact with the surface. The assembly can be rotated from the resting position to a rolling position with the axle positioned under the cooler and the wheels in contact with the surface to assist in transporting the cooler.

Vehicle wheel including spoke attachment

The vehicle wheel includes an outer rim hoop with means for holding a tire, a plurality of spoke portions, and a central hub assembly. The central hub assembly includes an axle assembly and a hub shell that is rotatable about the axle. The hub shell includes at least two axially spaced outer flanges for attachment with the spokes. The spokes are connected at their outer ends to the rim hoop and at their inner ends to their respective outer flange. Firm attachment between the spoke and the outer flange is achieved by engaging of a portion of the spoke with a cavity formed within at least one of the rim and the outer flange. Also disclosed are attachment arrangements that include an intermediate connection member to facilitate attachment between the spoke and the cavity.

Light-weight vehicle wheels with carbon fiber inserts

Application of carbon fiber reinforced polymer structures to metal vehicle wheels is effective in reducing the mass of the wheel while retaining suitable stiffness in the wheel structure. For maximum effect the reinforced polymer structure and the metal wheel must operate cooperatively. Because of the wide range of operating temperatures experienced by wheels and the large difference in coefficient of thermal expansion between metals and carbon fiber reinforced composites attachment of the polymer structure to the wheel by adhesive alone is problematical. However a wheel with an effective and durable reinforcement may be fabricated by confining, through mechanical interference, the reinforced polymer in a cavity in or on the spoke and by preheating the wheel before curing the polymer.

Spoke for a tire with optimized thickness for improved durability

The present invention provides spoke geometry for a non-pneumatic tire that is less prone to fatigue when used. In particular, the spoke geometry is provided with an optimized thickness profile over the length of the spoke. This optimization results in a reduction in the peak strain energy density levels in the spoke, thereby reducing the likelihood of crack initiation and propagation which in turn enhances the durability of the spoke and tire.

Wheel and a bicycle equipped with such wheel

A bicycle that includes front and rear single-arm forks enabling the front and rear wheels to be mounted and demounted from the frame of the bicycle without necessitating the removal or repositioning of a transmission element, such as a chain, or the brake, if the bicycle is so equipped, each of the wheels including at least one flexibly and compressively rigid element connecting the central hub and the rim, such elements being asymmetrical with respect to a radial median plane defined by the rim, so that the hubs of the wheels are axially off-centered in relation to the radial median plane of the rim, while the radial median plane of the rims coincides with the general median plane of the frame. The invention is also directed to the wheel of the bicycle.

Apparatus for twist-to-lock retention of a wheel

The invention relates to a quick release assembly for a bicycle, wherein the assembly comprises an axle having a first non-cylindrical end portion, a cylindrical central portion, and a second non-cylindrical end portion, wherein a diameter of one of the non-cylindrical end portions is larger than the diameter of the cylindrical central portion. The quick release assembly further comprises an insert having a non-cylindrical outer profile configured to be retained in a non-cylindrical opening and having a cam surface disposed therein, wherein the insert is sized to retain one of the non-cylindrical end portions of the axle therein. The assembly also includes a shaft sized to pass through the axle and having a cam follower on a first end and a handle on a second end, wherein the cam follower is configured to form a locking engagement with the cam surface upon an axial rotation of the handle.

Manufacturing method for irregular-section tubular body and axle beam for torsion beam

The present invention intends to provide a manufacturing method of an irregular-section tubular body in which a manufacturing process is simplified, and complexing and large-sizing of an equipment, and increase of an equipment cost are avoided. In the manufacturing method of the present invention, a tubular worked body 1 sealed liquid W therein is press-formed by a press upper mold 6 and a press lower mold 3. One of the press upper and lower molds has one convex mold portion 3a to form a concave portion 1a concaved in an axis perpendicular direction at an axial part. The press-forming of the worked body to the tubular body is completed by one stroke process by using a liquid pressure increasing as decrease of internal volume of the worked body due to formation of the concave portion. Thus, liquid in the worked body is not pressurized by a pressurizing device after the press-forming.
