A decoupling element for reducing structure-borne noise, particularly for use in a heat shield system, having a sleeve element with an insertion opening for the insertion of a fastener for fastening to a partner fastener, wherein the insertion opening extends in an axial direction of the sleeve element and the sleeve element has collars protruding in a radial direction, which are spaced apart from each other in the axial direction, wherein between the collars, a damping element is positioned, which extends radially outward beyond the collars and is provided to be fastened to a heat-shielding part by means of a fastening element, and the damping element is embodied as a metal wire structure, wherein the damping element is positioned so that it is elastically prestressed in the axial direction in a gap between the collars of the sleeve element.

The present invention relates to a clamp assembly for securing a variety of equipment. The clamp assembly comprises a top portion, a bottom portion, a first side and a second side. The top portion comprises a first surface and a second surface separated by a first channel that is configured to receive an accessory. The bottom portion has a cavity for mounting the clamp assembly on a structure. The first side comprises a first securing hole and a second securing hole, each configured to receive a first securing means and a second securing means. The second side comprises a second channel for receiving the accessory and a first blind hole and a second blind hole for securing the first securing means and the second securing means received through the first securing hole and the second securing hole.

A connector including: a first buffer member that includes a spiral-shaped wire in a plan view; a second buffer member that has a substantially annular and flat plate-like shape, and that is capable of warping in a thickness direction; a collar member that includes a cylindrical portion surrounded by the first buffer member and the second buffer member, a first flange facing a radially inner side of the first buffer member, and a second flange facing a radially inner side of the second buffer member; and a coupling member that includes a first holder section holding radially outer sides of the first buffer member and the second buffer member, a second holder section holding the shielding body, and a coupling member base portion.

Embodiments herein disclose a universal clamp assembly for clamping a solar panel. The universal clamp assembly comprises a securing means to secure a support structure, the support structure configured to couple with a rail of the solar panel and a shock absorbing member disposed between the securing means and the support structure to keep the securing means in place during installation. The securing means comprises a first channel, a second channel, a first securing hole, at least one first hole, at least one first pin, a protruding structure and a grooved wall. The support structure comprises a second securing hole to secure a securing member disposed through the first securing hole of the securing means, thereby joining the securing means and the support structure, a first lateral wall, a second lateral wall, a first coupling member and a second coupling member to secure the universal clamp assembly in the rail.

A fastening arrangement with damping effect, consisting of two structurally identical fastening units each having a central first through opening. Each fastening unit comprises a mounting element and a damping element. The mounting element is disc-shaped with a central second through opening and an identical detent structure extends from a first side of each mounting element. The damping element is disc-shaped with a central third through opening and is arranged at last partially in the central second through opening of the mounting element. Due to this construction the two fastening units can be fastened to one another by means of the mutually facing first sides having the identical detent structure of the respective mounting elements with first component arranged between them.

A plurality of raised surfaces on a platform absorb torque of a fastener contacting the surface while rotating relatively to the platform. Significant disproportionate increase in torque compared with the associated increase in bolt stress is observed by increased felt torque when tightening the fastener. Raised surfaces are used on lugs of a mechanical pipe coupling to increase the fastener's resistance to damage when powered tools are used to apply torque to the fastener.

A damping arrangement which is fastenable in an opening of a first component and by which a dampened connection of the first component with a second component is realizable, including, two identically constructed damping elements. Each damping element includes: a head portion with a first outer diameter, a shaft portion with a second outer diameter that is smaller than the first outer diameter and extends from a bottom side of the head portion, as well as a central first thru-opening, and only one sleeve with a central second thru-opening being arranged at least partly in the central first thru-opening of each damping element by means of a frictional and/or material connection. By means of the only one sleeve, the two identically constructed damping elements with bottom sides, facing each other, of the head portion with the first component arranged in between are fastenable to one another.

A self-tightening fastening apparatus for vibrating work-parts includes a male fastener, a main female fastener, a locking female fastener, an anti-rotation female fastener, and a first compression body. The main female fastener is threadedly engaged around a first threaded-shaft section of the male fastener, wherein a head of the male fastener and the main female fastener compress the vibrating work-parts together. The locking female fastener is threadedly engaged around a second threaded-shaft section of the male fastener. The first compression body is compressed in between the main female fastener and the locking female fastener. The anti-rotation female fastener is threadedly engaged around a third threaded-shaft section of the male fastener.

Disclosed are a bolt fastening structure which is couplable and releasable at one side and includes a fall prevention washer capable of preventing a bolt from falling, and an anti-vibration device including the same. By using an L-shaped bolt having a bent portion, even without assistance from below a substructure such as a grating plate, an operator above the substructure can install an anti-vibration device on equipment alone. In addition, by using a fall prevention washer coupled to an L-shaped bolt, a bolt can be prevented from falling below a substructure when working on the substructure.

The disclosed embodiments relate to a screw nut and an electronic device having the same. The screw nut is configured for fixation of a fastener. The screw nut includes an inner nut component, a cushioning component, and an outer nut component. The inner nut component has a screw hole portion configured for fixation of the fastener. The cushioning component is sleeved on the inner nut component. The outer nut component is sleeved on the cushioning component. The cushioning component is connected between the inner nut component and the outer nut component so that the inner nut component is movably connected to the outer nut component.
