A coupler system for connecting elongate, horizontally disposed rods to vertical supports includes a top-cap component for attaching to the top of a vertical support. The top-cap support includes a body with plural cavities, and at least one ball-cap component for attaching to an end of a rod. The ball-cap component includes a ball region that fits within one of the plural cavities. The body may be formed with four plural cavities, each having beveled edges. The ball-cap component may include a ball region, a neck region, and an angled region located adjacent the neck region and away from the ball region. The top-cap and ball-cap components may include insertion regions with opposing sets of ribs. The coupler system may further include a cover component, and the body may be formed with a central hole for receiving a fastener that secures the cover component to the top-cap component.

A clasp includes a hook component and a catch component, which may be used to releasably attach two ends of an article. Among other elements, the hook component may include a stem (for manually operating the clasp) and a cantilevered lip suspended above the stem to form a slot for receiving a part of the catch component. In addition, the catch component may include a slot-engaging portion that is coupled between the stem and the cantilevered lip.

Devices and methods based upon the concept of a split ring (604) having certain multiple interior angles (604a, 604b) to engage a stem or post (608) having annular ring(s) with angular geometries that are complimentary to those of the split ring. The disclosure provides designs for a wide range of insertion and desertion forces between latch engagement stems and latch engagement bodies. Changes to insertion contact angles and contact area on engagement stems and corresponding changes to insertion contact angles and engagement areas on engagement bodies can significantly modify insertion forces required to engage various devices. Similarly, changes in degrees of angle between desertion angles and contact areas on engagement stems with corresponding changes in desertion angles and contact areas on engagement bodies will significantly modify the total desertion forces required to disengage various devices. Accordingly, the instant latching mechanism provides insertion and desertion forces that can be controlled independently of each other.

A fastener assembly is provided including a fastener body having at least one aperture and a cavity formed at a top portion. A cap is provided configured to be removably inserted into the cavity. A method for fastening an article is provided including providing an article having holes in opposing edges of an article opening and a lace passed through said holes. At least one fastener body is provided having an attachment point, wherein the lace is secured to the attachment point, forming at least one slack portion. Each slack portion is pulled through a set of holes in the opposing edges of the article to form lace loop(s). Each lace loop is overlapped over the at least one fastener body.

A fastener assembly attaches items to fabrics and textiles. The fastener has particular application for easily attaching racing bibs (i.e., athlete numbers) to athletic garments, and obviating the need for safety pins. In one embodiment, a female portion that passes through the fabric or textile releasably connects with the male portion that fastens the item to the fabric or textile. In another embodiment, the female portion has a cover to facilitate passage through the fabric or textile. In a third embodiment, the male portion passes through the fabric or textile, and includes a barb or a hook to do so.

Among other elements, the hook component may include a stem (for manually operating the clasp) and a cantilevered lip suspended above the stem to form a slot for receiving a part of the catch component. In addition, the catch component may include a slot-engaging portion that is coupled between the stem and the cantilevered lip.
