摘要:
Impact attenuating/spring systems may include first and second body portions and at least one spring member at least partially included between the body portions. The spring member(s) may substantially enclose and/or be pivotally engaged with the body portion(s). The components of the impact attenuating and spring element may be arranged such that when a force is applied to the body portion(s), the spring member(s) will exert a counter force to urge the impact attenuating and spring element back toward its original orientation. The spring members may include one or more polymeric element that stretches under a tensile force. The impact attenuating and spring elements may be included in a piece of footwear or other device in a manner such that a user or a retailer (or others) can select an appropriate spring member (or portion thereof), e.g ., depending on characteristics of the user or the intended use.

The invention relates to a protecting apparatus (10) for protecting a structure (100) from an impact. The protecting apparatus (10) is arranged to be mounted on the structure (100) and includes a bumper member (12), a structure positioning member (14) and at least one resiliently flexible joining portion (16). The structure positioning member (14) is arranged in use to be positioned in contact with or adjacent to a portion of the structure (100) being protected. The at least one resiliently flexible joining portion (16) extends between the bumper member (12) and the structure positioning member (14) so that when an outer surface (12a) of the bumper member (12) is impacted, the impact force is dissipated at least in part by flexure of the at least one joining portion (16).

An impact energy absorber, characterized by comprising a mechanism to absorb an impact energy by the movement of top face materials (3) and the compressive or deflective deformation of columnar bodies (2) caused when a long member (1) is deformed when subjected to an impact force, wherein the long member (1) of high strength material is disposed in such a direction as to be different from an impact force input direction and both end parts of the long member (1) are connected to each other through the top face materials (3) to cover the top faces of the columnar bodies (2) vertically installed apart a specified distance (L) from each other, whereby an impact energy characteristic equal to or more than that when the absorber is ruptured in axial direction can be developed even for impacts also from a wide angle ( theta ) such as an impact from an oblique direction considered to be the weak point of a columnar energy absorbing member, and the device can be recovered easily by part replacement even if a damage is given thereto.

The invention relates to an attenuation device comprising a surface of revolution (11) with a circular transverse section. Moreover, a set of grooves (14) are distributed between the two sides of the surface of revolution (11) and are designed to confine an elastic material (15) within the limits defined by the aforementioned grooves (14). In this way, a structural labyrinth is formed for the passage of loads from a lower interface of the surface of revolution (11) to an upper interface.

Ein Schwingungsdämpfungssystem für Statorwicklungen umfasst eine Wicklung (2) eines Stators (1), welche an einem Stützbauteil (3) des Stators (1) unter Zwischenschaltung eines Dämpfungselementes (4) gehalten ist. Außerhalb des Stators (1) ist eine Steuervorrichtung (7) angeordnet, die in Zusammenwirkung mit einem im Stator (1) angeordneten Stellelement (5) eine Änderung der Dämpfungseigenschaften des Stators (1) ermöglicht.
摘要:
A longitudinal inertial force (a) produced by a piston (14) is cancelled by an inertial force (b) produced by a crank shaft (15), and secondarily produced right and left inertial forces (c, d) vibrate the outboard motor main body right and left around an imaginary center of vibration (C). At this time, an elastic body (74) elastically supporting the outboard motor main body on the ship is set in such a manner that tangential (L3-direction) rigidity around the imaginary center of vibration (C) is lower than radial (L2-direction) rigidity around said imaginary center of vibration (C); therefore, said right and left vibration is effectively reduced by the low rigidity of the elastic body (74). Propeller thrusts (e, f) acting in a longitudinal direction (L1-direction) are transmitted to the ship through the elastic body (74). Since the rigidity of the elastic body (74) along this direction is set at a high value, the propeller thrusts (e, f) can be effectively transmitted to the ship.
