A leaf spring made of a fiber composite material having integrated bearing holes and a method for producing is disclosed. The method comprises the steps of cutting prepreg strips of a predetermined length from a prepreg strand, removing cut-outs from the particular prepreg strip in the axial ends where a bearing hole should be formed, laying a plurality of prepreg strips one over the other in a prepreg stack in alternation so that the surfaces of the prepreg strips are flush to form a raw leaf spring forming a bearing hole by deforming an axial end of the prepreg stack in a plane perpendicular to the longitudinal extension (L) and perpendicular to the transverse extension (B) of the prepreg stack, setting the raw sheet spring to form the finished leaf spring in a mold with a suitable setting pressure and a suitable setting temperature.

A torsional damper for a torque transmission device, comprising: a first element (1) and a second element (2) rotationally movable with respect to one another; and a first damping means and a second damping means, each damping means comprising: an elastically deformable blade (9) having a fastening portion (12) and an elastic portion (13), an abutment element carried by the other of the first and second elements and configured, for an angular deflection between the first and second elements with respect to an inactive angular position, to apply a flexural load onto the blade,
the elastic portion of the blade of the first damping means proceeds circumferentially beyond the fastening portion of the blade of the second damping means.

A flexure bearing includes an inner race, an outer race, and a plurality of substantially planar radially extending blades coupled between the inner and outer race. The blades have a thickness that is thinner than a thickness of the inner and outer races. The inner race, outer race, and blades have substantially the same height. At least one heating element is coupled to the inner race and/or the outer race. The heating element is configured to apply heat to the race that it is coupled to in order to tune the flexure bearing.

A wave spring includes an annular body in which crests and valleys are alternately and continuously formed in a circumferential direction. At least a portion of the annular body in the circumferential direction is a joined portion. The joined portion of the annular body is a flat portion extending in a plane orthogonal to a center axis of the annular body.

The present invention is an artificial grass block that can accommodate to the different sized cells of the similar grass pavement stones produced by different companies. The artificial grass block can bear an up to 10% size difference of the cells. The artificial grass block can carry out this function by its elastic, flexible positioning-fixing unit, which positions and fixes the artificial grass block inside the cell of a certain size range. The positioning-fixing unit is longer than the cell before insertion and deforms during insertion. This deformed positioning-fixing unit creates a tension that appropriately positions and firmly fixes the artificial grass block within the cell. EOIC 5/20 Pavings made of prefabricated single units; made of units of plastics; EOIC 9/225 Pavings specially adapted for allowing vegetation; EOIC 11/225 Paving specially adapted for through-the-surfacing drainage, e.g. perforated, porous; Preformed paving elements comprising, or adapted to form, passageways for carrying off drainage; E03F 11/00 Water supply; sewerage; Sewers; Cesspools; E04F 13/24 Finishing work on buildings; Coverings or linings, Hidden fastening means on the rear of the covering or lining elements; F16B 2/00 Friction-grip releasable fastenings; F16F 1/36 Springs, made of plastics.

A two-dimensional passive energy absorber device has an integral body with a first face and a second face separated by an edge height H. The body includes a platform, a rigid frame surrounding the platform, and a plurality of symmetrical flexible folded beams. The platform and the frame have the same profile shape is arranged to concentrically align, and each of the symmetrical folded beams connects between a frame edge and a platform edge that is not parallel to the frame edge.

Composite springs, composite spring assemblies, medical devices including the same, and methods of making and using the same are disclosed. The composite springs may comprise alternating layers of carbon fiber and fiberglass materials. A strengthening adhesive, such as an epoxy, may be used to bind the carbon fiber and fiberglass materials. A dampening member may be attached to the composite spring, thereby at least partially defining a composite spring assembly. The dampening member may dampen elastic/spring forces of the composite spring. The composite spring assembly may be attached to an orthotic device to provide a non-linear spring response during movement of the device.

A planar spring has an outer ring, an inner ring, and two elastic components. The inner ring is disposed in the outer ring, and forms a space therebetween. The two elastic components are disposed in the space, and are symmetric with respect to a central line at a spaced interval. Each elastic component has an outer connecting portion, an inner connecting portion, and a flexible strip. The outer connecting portion is connected to the outer ring at a first connecting point. The inner connecting portion is connected to the inner ring at a second connecting point. The flexible strip is connected between the outer connecting portion and the inner connecting portion. An included angle between the first connecting point and the second connecting point from the center is greater than or equal to 90 degrees and less than 180 degrees.
