A separator device for removing particles from suspension in a fluid includes first and second fluid-carrying portions and a non-fluid-carrying spacer for linking the first and second fluid-carrying portions. Each of the fluid-carrying portions includes a socket for receiving an open end of a pipe and a connector for connection of the filter. The socket of the first fluid-carrying portion has a pipe receiving depth greater than that of the socket of the second fluid-carrying portion. The sockets of the first and second fluid-carrying portions are positioned on a common axis and facing away from each other when the fluid-carrying portions are linked by the spacer.

A rail system. The rail system includes an upper rail member, a lower rail member and a plurality of balusters. The upper rail member, lower rail member and balusters secure together and to a support structure to form the rail system. The support structure may include columns, newels, walls and the like. The upper and lower rail members each include a cap that snaps onto a rail support. Fasteners may fasten the balusters directly to an upper rail support. Fasteners may further fasten the balusters directly to a lower cap.

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

A method for joining members according to an embodiment of the present invention includes: providing a bumper stay including two integrated pipe portions extending in an identical direction, the bumper stay including a recess provided between the pipe portions being adjacent to each other, the recess extending in a longitudinal direction of the pipe portions from end surfaces of the pipe portions, a part of the recess serving as a locking portion, and a bumper beam including a rear inclined wall formed with two hole portions into which the pipe portions of the bumper stay are insertable respectively; inserting the bumper stay into the hole portions of the bumper beam until the locking portion abuts on the rear inclined wall; and pipe-expanding an insertion portion of the bumper stay into the bumper beam to join the insertion portion to the bumper beam by press-fitting.

A snap coupling system for pieces or metallic or non metallic coupling members, that require to be attached perpendicularly in a T fashion, in a cross + fashion or angularly, by which a tubular male coupling member having one or more retention tabs that are temporally flexed, enters in slots or receiving apertures of another piece or female coupling member, tubular or planar, where they engage, by which they can be readily attached two tubular members or one tubular member and one planar member, in a perpendicular way, in a cross fashion or angularly, without the necessity of using skilled labor.

In the present invention, a method for joining members involves preparing a steel component having a bottom wall in which a hole is provided, and a hollow aluminum pipe. The aluminum pipe is slipped through the hole in the steel component and passed through the bottom wall, rubber is inserted into the interior of the aluminum pipe, and the rubber is compressed in the direction of the axis (L) of the aluminum pipe and induced to distend towards the outside from the inside. As a result of the foregoing, at least a section of the aluminum pipe slipped through the hole is induced to undergo expansion and is joined by clinching to the bottom wall. This method for joining members reduces the load on the members, improves the joint strength, and enables two members to be joined at reduced cost.

In a method for joining members of the present invention, a B-pillar, a rocker, a side panel served as frame members of a vehicle body, and an elastic body are provided. The B-pillar includes a tubular portion and an extension portion extended from the tubular portion. The rocker includes a first hole portion. The side panel includes a support portion. Next, the tubular portion of the B-pillar is inserted into the first hole portion of the rocker. The elastic body is inserted into the tubular portion of the rocker. The elastic body is pressurized in an axial line L1 direction of the tubular portion of the B-pillar to be expanded outward in a radial direction of the axial line L1, so that the tubular portion of the B-pillar is expanded and deformed to be joined to the first hole portion of the rocker by press-fitting. Further, the extension portion of the B-pillar and the support portion of the side panel are joined by a method different from joining by press-fitting.

Disclosed is a joining method of members, which includes the steps of: preparing a first member in which a first hole portion having a polygonal cross-sectional shape is formed, and a second member having a hollow shape, wherein the second member has a cross-sectional shape corresponding to the polygonal cross-sectional shape of the first hole portion, the second member including a plurality of straight line portions extending linearly and corner portions positioned between the adjacent two straight line portions in the cross-sectional shape; inserting the second member into the first hole portion of the first member; and caulking and joining the second member to the first member by enlarging and deforming the corner portions.

The joining method for members according to the present invention includes: providing an aluminum component including an insertion hole provided with a rib in at least part of an edge part, and a hollow steel pipe; inserting the steel pipe into the insertion hole of the aluminum component; and expanding and deforming the steel pipe to join the steel pipe to the aluminum component by press-fitting.
