A curtain wall panel mounting system comprises a ball anchor seated in a spherical cavity or a cylindrical cavity with plugs nearly abutting the ball of the anchor. A stem extends from the ball to connect to the wall panel. Under seismic stress, the ball may swivel within the cavity so as to pivot the anchor, allowing the attached wall panel to angle itself to accommodate the stress.

A spring-loaded fastening system for fastening a liner to a structure, including a spring-loaded fastener with a cleat defining an interior cavity, a spring element disposed on a floor of the interior cavity, and a shoulder bolt with head portion disposed on the spring element, with a shoulder portion of the shoulder bolt extending through a mounting aperture in a floor of the interior cavity and a threaded portion of the shoulder bolt fastened to the structure. The system further includes a hanger pocket in a rear surface of the liner including a first portion with an opening large enough to accommodate a diameter of a lower portion of the cleat and not large enough to accommodate a diameter of an upper portion of the cleat, and a second portion adjoining the first portion with an opening large enough to accommodate the diameter of the upper portion of the cleat.

The invention relates to a spring element for a device for compensating for tolerances between a first and a second component, characterized by at least one spring arm which has two opposite end regions along its longitudinal direction, wherein at least one of the end regions has a greater distance from a longitudinal central axis of the spring element than an intermediate section of the spring arm between the end regions, and wherein at least one of the end regions forms a corner which protrudes radially outwards.

A hung structure is provided. The hung structure is adapted to be hung on a fastener. The hung structure includes a hung member and a restriction member. The hung member includes an opening, wherein the opening includes an insertion area and a first slot area, the fastener is adapted to pass through the opening via the insertion area, the fastener is adapted to slide from the insertion area to the first slot area, and when the fastener is in the first slot area, the hung member is supported by the fastener. The restriction member includes an affixed section, an elastic unit and a restriction section. The affixed section is affixed to the hung member. The elastic unit is connected to the affixed section. The restriction section is connected to the elastic unit, wherein the restriction section corresponds to the insertion area.

A modular safety fence assembly is disclosed. The safety fence may include a fence panel assembly having a top rail, a bottom rail, and mesh panel. The safety fence panel assembly may also support post assembly capable of supporting the fence panel assembly and an anchor assembly which may anchor the support post assembly to the floor using one or more relatively shallow holes formed in the floor.

An assembly for securing a workpiece. The workpiece includes a bore having a first opening in a first surface of the workpiece. A limiter extends between a proximal end and distal end and defines a bore and is received in at least a portion of the bore of the workpiece. A fastener extends along an axis between a proximal end and a distal end. The fastener has a head at the proximal end and a plurality of threads at the distal end. The fastener is received in the bore of the workpiece so that the distal end of the fastener having the plurality of threads is opposite the first opening of the bore. A first spring element is disposed about the fastener and is between the head of the fastener and the first surface of the workpiece. The first spring element is configured to generate a deflection force when the first spring element is subjected to a compression force during a tensioning of the assembly.

An assembly of a pylon and of a nacelle of an aircraft, wherein the nacelle has a structure, a visor, two centering systems and two tensioning systems. Each tensioning system comprises a first fitting, which is attached to the structure and has an engagement wall through which an orifice passes, a second fitting, which is attached to the visor, a threaded rod that is articulated on the second fitting and passes through the orifice, a spring element fitted on the threaded rod against the opposite face of the engagement wall from the second fitting, and an arresting means that blocks the spring element. Each centering system comprises a first fitting, which is attached to the structure and has a bore, and a second fitting, which is attached to the visor and bears a shaft that is accommodated in the bore.

A floating fastener with shock-absorbing structure includes a base having a cylindrical portion and a bottom plate and an abutment ring and an inner ring formed in the cylindrical portion, a fixing element having a head, a shank and locking portion, a flexible liner having a top-sided positioning embedding portion placed in a first fixing hole of a preset first plate, a positioning tube having a tube body and a protruding ring portion, and a buffer pad having a ring groove positioned on the protruding ring portion of the positioning tube. The assembly structure of the positioning tube and the buffer pad is placed outside the cylindrical portion of the base from top to bottom through the perforation of the positioning tube to form a positioning, and the bottom side of the buffer pad is held against the upper surface of the preset first plate.

A fastener structure includes a body portion and a fastening body. The body portion has a solderable layer, and the solderable layer is soldered to a plate body. The fastening body combines movably with the body portion. The fastening body has a head and a fastening portion. The body portion or the fastening body, or both the body portion and the fastening body is provided on the plate body for soldering after it is picked up by a tool so that the body portion can combine with the plate body. Also, the body portion or the fastening body, or both the body portion and the fastening body combines with a assisting pickup unit, and the fastener structure is provided on the plate body for soldering after it is picked up by a tool through the assisting pickup unit so that the body portion can combine with the plate body.
