| 20090174128 | DEVICE FOR REGULATING THE ELASTIC FORCE EXERTED BY A PLURALITY OF SPRINGS - A device for adjusting the elastic force exerted by a plurality of springs, wherein there are provided main springs and auxiliary springs connected to two mutually movable structures. There are provided means for operatively coupling or uncoupling the connection of the free end of one or more of the auxiliary springs with respect to at least one of the structures. | 07-09-2009 |
| 20100289198 | MULTILAYERED CANTED COIL SPRINGS AND ASSOCIATED METHODS - Multilayered canted coil springs and methods that improve mechanical, electrical and thermal properties of canted coil springs. In some embodiments, properties of dissimilar materials are combined into the spring using various material layers. For example, in one embodiment a protective or high strength outer layer material shields a more sensitive inner core material from harsh environments and conditions. The inner core material may be a highly electrically conductive material, with the outer layer material having an electrical conductivity lower than the core. In various embodiments the following characteristics of the spring are improved: electrical and/or thermal conductivity, corrosion resistance, biocompatibility, temperature resistance, stress relaxation, variable frictional force, and wear resistance in harsh environments and conditions. | 11-18-2010 |
| 20100320658 | Apparatus for changing a leaf spring characteristic - The invention relates to an apparatus for changing a spring characteristic, which includes at least one tension and/or compression spring for changing the spring rate of a leaf spring to which the apparatus can be connected, wherein a mounting device for mounting the tension and/or compression spring on the leaf spring is connected to a first end of the tension and/or compression spring. | 12-23-2010 |
| 20110278778 | Self Centering Spring Linkage - Methods and apparatus for a bi-directional self-centering linkage are provided. The bi-directional self-centering linkage contains a compression spring sliding shaft assembly that may be pre-loaded to a predetermined calculated value. The bi-directional self-centering linkage is adjusted and then installed to connect with an outside mechanical device that transmits a force to the bi-directional self-centering linkage. The compression spring sliding shaft assembly either transmits or dampens the force applied. An alternate embodiment provides electromagnetic actuation. | 11-17-2011 |
| 20120025435 | SPRING AND SPRING ASSEMBLY - A spring includes a first end, a second end, and a spring main body between the first end and the second end. The spring main body includes a compression spring portion and a torsion spring portion, and the spring main body is substantially located in a same plane. | 02-02-2012 |
| 20130069291 | TELESCOPING SPRING ASSEMBLY FOR MATTRESSES AND THE LIKE - A spring assembly includes telescopically adjustable inner and outer members biased in an extension direction by a coil spring. A non-stretch fabric sleeve fitted about an inner diameter and an outer diameter of the coil spring is closed at its opposite ends to apply a compression preload to the coil spring. The fabric sleeve prevents transmission of the preload to the inner and outer telescoping members, thereby eliminating stickiness and the popping sound that are drawbacks of the prior art, and the fabric sleeve also provides general noise reduction when the spring assembly changes length. | 03-21-2013 |
| 20140265077 | Negative Spring Compensation for Elastomeric Bearing Torque - Elastomeric bearings exhibit a reactive positive spring effect, i.e., they produce an opposing torque or force when angular displacement or translation is applied upon them, due to shear stress developed within their elastomer parts. The present invention incorporates a device that exhibits an increasingly strong torque or force in the same direction as the displacement, i.e., a negative spring, under similar conditions of movement. When properly calibrated, the subject type of device can be used in paralleled motion with the ordinary reactive elastomeric bearing to produce a combined effect in which at least a part of the torque or force of the elastomeric bearing is changed or minimized over a range of movement. | 09-18-2014 |
| 267152000 | Rubber | 1 |
| 20090039578 | TENSION-COMPRESSION SPRING - A tension-compression spring with high utilization of properties of the material from which the spring is fabricated wherein displacements between conforming and interacting beveled surfaces of rings constituting the spring are accommodated by internal shear in an elastomeric layer or layered (laminated) element residing between the conforming and interacting beveled surfaces of the rings. | 02-12-2009 |
