A bushing assembly for tubular structures is disclosed. The bushing assembly includes a body having a substantially flat configuration and defining a planar surface and an outer edge; and a plurality of projections extending from the outer edge and traverse to the planar surface, each projection defining a longitudinal axis, each projection including at least one ridge extending at least partially along a surface of the projection and along the longitudinal axis.

A grommet (200, 300, 400), a stud (102), an assembly of a grommet and a stud forming a fastener (100), and a method of assembling a grommet and a stud to form a fastener has the grommet with an interengaging element (250) in a channel wall of the grommet for engaging a cooperating, compatible or complementary interengaging element in a wall of the stud. The grommet and the stud can be assembled by moving the grommet and the stud relative to each other until the interengaging element in the grommet engages the complementary interengaging element in the stud. A family of grommets is described.

A screen arrangement (10) including a stringer (16), a securing arrangement (18), and a plurality of screen panels (20) adapted to couple to the stringer (16) by the securing arrangement (18). The plurality of screen panels (20) may each include a side notch (22) arranged to define a screen aperture (24) between adjacent ones of the plurality of screen panels (20) and the stringer (16) includes a stringer aperture (26) aligned with the screen aperture (24). The securing arrangement (18) may include an expandable part (28) adapted to extend from the screen aperture (24) into the stringer aperture (26) and a fastener (30) adapted pass between the screen aperture (24) and the stringer aperture (26) so as to expand the expandable part (28) within the stringer aperture (26). A related method is also disclosed.

A framing system includes a first connection assembly that engages with a substrate. The first connection assembly includes a first connector and a track. At least one spring flange defined by the first connector engages with a fastener positioned along the substrate to maintain the first connection assembly in a fixed position relative to the substrate and to interconnect the substrate with the track. The framing system further includes a second connection assembly defining a second connector engaged to a stud. The second connection assembly engages with the first connection assembly to interconnect the stud with the track.

A connecting bolt has a bolt shank and a bolt head which has a radially outwardly projecting bolt projection. The bolt head has a latching projection between the bolt shank and the bolt projection on the side opposite the bolt projection.

A quick disconnect mount includes a mounting stud securable to a structure, and a connector securable on the mounting stud. The mounting stud includes at least one circumferential ridge and at least one circumferential trough, and the connector includes a central channel sized to fit over the mounting stud and a locking bar engageable with the circumferential trough.

A joined body includes: a first member having a pipe shape; and a second member including a wall portion having a plate shape, and a flange portion having a cylinder shape provided with an insertion hole through which the first member is inserted. In a state where the first member is inserted into the insertion hole of the flange portion of the second member, the first member and the second member are joined with the first member pipe-expanded. A material of the second member is larger than a material of the first member in a spring-back amount.

A quick disconnect mount includes a mounting stud securable to a structure, and a connector securable on the mounting stud. The mounting stud includes at least one circumferential ridge and at least one circumferential trough, and the connector includes a central channel sized to fit over the mounting stud and a locking bar engageable with the circumferential trough.

A device for securing accessories such as bins, hooks, shelves, mirrors, trays, and baskets to a vertical support pole without tools and without a separate wedge or collar, including two fully separable pieces that interlock to surround the support pole and a lever that tightens to the pole without the use of a separate sleeve or wedge and without using tools.

The present display system enables the display and rearrangement of one or more decorative elements on a base structure to create a decorative arrangement that can be easily and selectively adjusted to move or rotate the decorative elements. The display system generally comprises an attachment assembly mounted on a base structure and supporting a decorative element support. An angular adjustment lock and a lateral adjustment lock permits the decorative element support to rotate and translate relative to the base structure. The base structure comprises one or more mounts arranged on a face of the base structure. The mounts receive and support one or more attachment assemblies. Using the present display system, multiple decorative elements can be adjusted to create aesthetically pleasing compositions of complementary or connected decorative elements.
