Abstract: The invention structure of wheel rim cover includes: a cover body whose disc surface has a plurality of spokes separated by openings; many fasteners are set on an outer edge of a rearward end hole of each opening. The fasteners are grouped surrounding the end hole of a same opening, and are jointly supported by a spring ring. The whole cover body can make use of the fasteners to latch on the end hole of the opening of a targeted wheel rim to fasten the cover body on the wheel rim.

Abstract: A wheel rim covering structure of the invention includes: one cover body, which has a cover surface and ring spoke edge is formed on it. Many costal bodies and engraved holes are sit on the cover surface, and the shrinking hole edge of each engraved hole would form an end hole at the backside of the cover surface. The hole edge is equipped with a plastic made fastener assembly which was formed as one with the cover body. Such fastener assembly each has a suitable length stem. A buckling part would be set at one end of the stem to co-surround to establish the first ring diameter and has the first height, from ring spoke edge to the end of the fastener assembly part. By means of stem of the fastener assembly extends into the engraved holes of wheel rim and the buckling part would buckle up the inner edge of each engraved hole respectively. Hence, the whole wheel rim cover body could be poisoned stably.

Abstract: The invention structure of wheel rim cover includes: one cover body whose disc surface forming many costal bodies and engraved holes; many fasteners are set on the same outer hole edge of the near end hole of the engraved hole; such fasteners become a group, surrounding outside of the end hole of the same engraved hole, and are jointly supported by a coil spring. The whole cover body can make use of the fasteners to latch on the end hole of the engraved hole of the targeted wheel rim and be fastened on the wheel rim.

Abstract: An extensional hubcap docking structure. The structure includes anchoring mounts positioned on the back surface of a hubcap. Clip components are coupled onto the anchoring mounts, and elastic components are situated between each hubcap anchoring mount and clip component. When the hubcap is fully installed onto the wheel of a tire and the hubcap is subjected to an outward force that subsequently pulls the anchoring mounts, the elastic components compress and rebound such that the hubcap is kept safely and tightly positioned on the wheel rim.

Abstract: An extensional hubcap docking structure comprised of anchoring mounts disposed on the back surface of a hubcap and clip components coupled onto the anchoring mounts. Elastic components are situated between the hubcap anchoring mounts and the clip components. When the hubcap is fully installed onto the tire wheel and the hubcap is subjected to an outward force that displaces the anchoring mounts outward, the elastic components deform and shift such that the hubcap is kept safely and tightly positioned on the wheel rim.

Abstract: A rotating hubcap comprised of a hubcap having a hole in the center, a seat, and a bearing installed in the seat. A turntable is pivotably positioned in the seated bearing, a revolving member is fastened onto the turntable, the opening in the center of the revolving member is sleeved onto the shaft member on the turntable, and the shaft members on the turntable exposed through the revolving member opening are then inserted into the bearing, such that the revolving member gyrates independently as a motor vehicle is driven.

Abstract: The present invention comprises a footrest with a poking rod; a bumper with an embedding hole is formed on the footrest; a latch member having two bent latch plates, each latch plate having a latch groove with a corresponding concave neck disposed inwardly, and a corresponding concave latch fork inwardly disposed, a latch wing outwardly disposed is formed on the latch groove; a corresponding outwardly protruded extension section is defined under the latch groove; such that the poking rod is clipped by the two plates of the latch member, and engaged by the latch fork. The footrest with the latch member and the poking rod are fully embedded and inserted into the embedding hole on the base of the bumper and secured into a fixed position.

Abstract: In the present invention, an edge is extended from the rim of a circular disc of a wheel cover, and such edge is the portion that the circular disc of the wheel cover exceeds the rim of the steel wheel, having an appropriated width to sufficiently block the thickness of the tire and make the tire look thinner.

Abstract: Methods and vectors (both DNA and retroviral) are provided for the construction of a Library of mutated cells. The Library will preferably contain mutations in essentially all genes present in the genome of the cells. The nature of the Library and the vectors allow for methods of screening for mutations in specific genes, and for gathering nucleotide sequence data from each mutated gene to provide a database of tagged gene sequences. Such a database provides a means to access the individual mutant cell clones contained in the Library. The invention includes the described Library, methods of making the same, and vectors used to construct the Library. Methods are also provided for accessing individual parts of the Library either by sequence or by pooling and screening. The invention also provides for the generation of non-human transgenic animals which are mutant for specific genes as isolated and generated from the cells of the Library.

Abstract: In the present invention, a first set of latch members and a second set of latch members are disposed on a wheel cover; wherein the first set of latch members encloses a first circular area with a first diameter D, the second set of latch members encloses a second circular area with a second diameter d, and the first diameter D is larger than the second diameter d, such that the wheel cover uses different sets of latch members to enclose areas of different diameters and fits the installation of different sized wheels.

Abstract: A steel wheel with a retaining base. The steel wheel includes a bearing, a turning disc, an axle disposed on the turning disc and pivotally coupled to the bearing on the retaining base. A wing plate is defined on the turning disc so that the wing plate rotates independently from the wheel cover when the vehicle is moving.

Abstract: A wheel cover. The wheel cover includes engraved holes with special shapes on a circular disc of the wheel cover, latch members on the backside of the wheel cover, and the latch members define a diameter of an area on the wheel cover for embedding the steel wheel. A turning disc is disposed on the wheel cover. An axle is disposed on the axle and pivotally coupled to a bearing on the wheel cover. A wing plate is defined on the turning disc, and the wing plate rotates independently from the wheel cover when the vehicle is moving.
