| 20100301531 | ELASTIC SUSPENSION MEMBER OF PLASTIC MATERIAL AND OF THE SPRING OR BALL AND SOCKET TYPE OR THE LIKE FOR BED BASE, MATTRESS OR SEAT - The invention relates to an elastic suspension member of the plastic material and of the spring or ball and socket type or the like, that comprises a base ( | 12-02-2010 |
| 20110095461 | ELASTIC ASSEMBLY AND SLIDE MECHANISM USING THE SAME - An elastic assembly for a portable electronic device includes at least two springs and two bushings. Each spring has a different curvature radius and two annular connecting portions at two ends, the connecting portion of each spring having a different diameter relative other connecting portion of other springs. The springs are substantially arranged in a plane, the two connecting portions of each spring are respectively coiled around and secured to another two connecting portion of another spring, the two bushings are respectively secured to the two connecting portion having the smallest diameter. The disclosure also discloses a slide mechanism using the elastic module. | 04-28-2011 |
| 20130099434 | SILENCER FOR A MULTI-LEAF SPRING - A silencer for a leaf spring assembly. The silencer is disposed between end portions of leaf springs. The silencer has a two-layer structure which has a fixing layer and a sliding layer which are integrally formed. The fixing layer has a projection portion, and the projection portion has an engagement portion at a leading end portion thereof. The fixing layer, which is fixed at the fixing side leaf spring, has a tensile strength higher than the sliding layer. The sliding layer, which abuts the sliding side leaf spring, has a hardness lower than the fixing layer. The projection portion of the fixing layer can have sufficient strength to resist the shearing force. In the sliding layer, undesirable noise generation is difficult, and even when a load transmission portion of an end portion of the sliding side leaf spring partially abuts the sliding layer, undesirable noise generation can be prevented. | 04-25-2013 |
