Embodiments of the present invention provide a connection system with a projection on a first connector and a co-operating cavity on a second connector to provide push-through connection of the connectors in first and second configurations in which the projection extends to first and second depths respectively within the cavity, wherein one or more of the projection or cavity is movable in two dimensions perpendicular to a longitudinal axis of the projection when received in the cavity, wherein the first and second connectors have cooperating locking surfaces arranged to engage each other when the projection is received at the second depth to prevent said movement in two dimensions and wherein the cooperating locking surfaces do not engage each other so as to prevent said movement in two dimensions when the projection is received at the first depth in the receiving cavity.

An adaptor is used to couple a prime mover to an actuator. The adaptor includes a first portion that attaches to the prime mover and a second portion that attaches to the actuator. The outer surface of the first portion is defined by at least one flat portion connected by at least one arcuate portion. The second portion has a bore configured to accept the first portion, with an inner surface shaped to complement the outer surface of the first portion. A bore through the first portion accepts a drive shaft of the prime mover therethrough where the drive shaft is configured to engage the actuator.

A joint system including a support device with a plurality of radial extensions extending in at least a first direction from the support device, each individual radial extension of the plurality of radial extensions terminating at a distal engagement end and a receiving device separate from the support device with a notch area to receive the distal engagement ends of each radial extension of the plurality of radial extensions and a contact area upon which a length of the radial extensions of the plurality of radial extensions engage when the distal engagement end of each radial extension of the plurality of radial extensions are engaged within the notch area. At least one radial extension of the plurality of radial extensions is configured to be flexible between a first position to provide for at least one of assembly and disassembly of the support device to the receiving device and a second position when the support device and the receiving device are assembled. Another system and method are also disclosed.

An additively manufactured auxiliary device has a device body with a lower face, which is integrally connected to a component, and at least one mounting element, which projects from an upper face of the device body, wherein the at least one mounting element is arranged such that a contact face and at least one fastening element of the connection part can be attached to the device body such that the contact face of the connection part rests against the upper face of the device body in a planar manner, and such that each mounting element of the device body adjoins a fastening element of the connection part.

A securing arrangement for securing at least one component to an appliance is provided. The at least one component is arranged on a receiving region of the appliance. The securing arrangement comprises a securing element configured for locking connection of the at least one component to the appliance. The securing element comprises a plate and has weakened regions and deformation zones between at least one peripheral, unweakened receiving region and at least one pressure and centering region resting on a surface of the component. The securing arrangement further comprises a plurality of spacers extending from the receiving region of the appliance to below the height of the surface of the at least one component. The at least one unweakened receiving region of the securing element is configured to be braced against the spacers.

This invention relates to an assembly of regions (10a, 10b) of composite parts (2a, 2b) with thermoplastic matrix, including a plurality of riveting points along regions (10a, 10) of the parts that overlap through the superposition of two faces (12a, 12b) of these regions (10a, 10b) which are positioned facing one another, each region (10a, 10b) having another, opposite, face (11a, 11b) which remains visible with the part (2a, 2b). The riveting is performed using assembly ties (6) made of thermoplastic resin-based composite material compatible with the material of the parts (2a, 2b). These ties (6), which are made up at least in part of a stitch of backstitch produced using a filament of a material selected from a fiber coated with aramid resin, a carbon fiber and a glass fiber, are embedded in said regions (10a, 10b) and passing right through the same with an orientation comprised between 30 and 90 with respect to their faces (11a, 11b; 12a, 12b).

A joining method for members includes: providing a steel component 10 including insertion holes 14a and 15a, an aluminum pipe 20 having a hollow shape, and a support component 30; inserting the aluminum pipe 20 into the insertion holes 14a and 15a of the steel component 10; and enlarging the aluminum pipe 20 through deformation and joining the aluminum pipe 20 to the steel component 10 by press-fitting. The press-fit joining is performed while at least part of the support component 30 is disposed in a press-fitting region.

The first fastener comprises a post, a fifth outer boss, an outer slab, a first hole and a second inner flange. The fifth outer boss is provided in an upper portion of the post. The outer slab perpendicular to the post is provided in a lower portion of the post. The first hole is provided within a local region of the outer slab below the post. The second inner flange is provided on an inner wall of the first hole. The second inner flange has a first gap greater than a width of the fifth outer boss. The upper surface of the second inner flange is used for abutting on a lower surface of a fifth outer boss of a second fastener having a same structure as the first fastener when limiting a position of connected pieces in a height direction of the post. Two sections of the second inner flange and two sections of the first gap are provided on the inner wall of the first hole in a staggered manner. Each section of the second inner flange is equivalent to of a circumference of the inner wall of the first hole. Each section of the first gap is equivalent to of the circumference of the inner wall of the first hole.
