Aspects of novel connection systems and methods are disclosed herein. A partially hollow nose is configured to one of connect a pathway to a body catch to accept a quick connect body (QCB) or mate with a connection system configured to be inserted into a shaped cavity in the nose; and, a quick connect module (QCM) and the nose are configured to cooperate to accept insertion of the QCB through the side wall of the nose into the body catch of the QCM; wherein the QCB affixes the QCM into the nose; and, wherein pushing on the button at one end of the QCB compresses the integral biasing arm of said QCB opening a catch and release interface to accept a tool.

The present disclosure provides an assembly having a plurality of cable trays, a first cable tray of the plurality of cable trays including a bottom and a set of upright sides extending between a first end and a second end, and a barb and a barb opening along each upright side of the set of upright sides. The barb may extend from an end of the barb opening, wherein a portion of the opening of a first cable tray of the two or more cable trays extends beyond, and remains uncovered by, a second end of a second cable tray of the plurality of cable trays when the first and second cable trays are connected.

The present aspects include an assembly having discretized and segmented joint architecture. The assembly comprises a first structure including an outer wall and an inner wall, wherein the outer wall and the inner wall extend from a base of the first structure, and define a groove, and a plurality of connecting walls extending between the outer wall and the inner wall such that the groove is divided into a plurality of groove segments defined by the outer wall, the inner wall, and the plurality of connecting walls. The assembly further comprises a second structure including a plurality of tongue segments which extend into the plurality of groove segments. A first adhesive is inserted into the groove, thereby bonding the plurality of tongue segments within the plurality of groove segments such that the first and second structures are fixed together.

A washing appliance with an agitator post configured for removable positioning in a receptacle. A shaft may be supported by the agitator post, the shaft rotatable relative to the agitator post. A plurality of movable tabs may be positioned at the bottom end of the agitator post and in mechanical communication with the shaft such that a direction of rotation of the shaft causes the plurality of movable tabs to be selectively movable along a radial direction between an extended position in contact with the receptacle that prevents rotation of the agitator post relative to the receptacle and a retracted position that allows rotation of the agitator post relative to the receptacle.

An above ground frame pool (10) includes a frame assembly (20) and a liner (40) supported by the frame assembly (20). The frame assembly (20) includes a plurality of horizontal pipes (22), a plurality of vertical pipes (24), and a plurality of T-shaped joints (30). The joints (30) may lack mechanical fasteners with adjacent pipes or corresponding apertures. The joints (30) may be one-piece or multi-piece structures. Such joints (30) maybe water-resistant and convenient to manufacture, assemble, disassemble, and store.

A metallic-composite joint fitting is provided. The fitting may comprise a frustoconical internal bearing having a bore, a conical sleeve configured to be disposed about the frustoconical internal bearing, a composite structure configured to couple between the frustoconical internal bearing and the conical sleeve, a metallic end fitting configured to be disposed within the bore and couple to the frustoconical internal bearing, and an external nut configured to couple to the metallic end fitting and the conical sleeve, wherein at least one of the frustoconical internal bearing or the conical sleeve comprises a flanged portion mutually configured to couple the conical sleeve to the frustoconical internal bearing via a locking ring.

A hose adapter may include an outer tube, an inner tube, a hose connector, and a hose. An inner peripheral ring protrudes from the inner periphery of the outer tube while an expanding ring portion protrudes from the outer periphery of an end of the inner tube. The outer periphery of the inner tube further has a first peripheral recess, a second peripheral recess, and a first outer thread, and a first O-ring and a second O-ring are respectively disposed on the first peripheral recess and the second peripheral recess. The inner tube is inserted into the outer tube, and the expanding ring portion is abutted against the inner peripheral ring, and the first O-ring is coupled between the outer tube and the inner tube while the second O-ring and the first outer thread are adapted to pass through and be exposed out of the outer tube.
