An accessory mounting track provides quick and easy removable attachment and positioning of various devices. The method of attachment of devices to the accessory mounting track may be compatible with the attachment of these devices to other mounting systems, allowing the accessory mounting track to be used interchangeably with those systems.

A coupling apparatus that is configured to provide a movable connection between at least two support members wherein the coupling apparatus can be deployed as part of devices in a plurality of applications. The present invention includes a housing wherein the housing is oval in shape having a first end and a second end. The opposing sides of the housing are formed with openings wherein the openings are substantially the size of the opposing sides. A top wall and bottom wall are present in the housing having apertures formed in the center thereof. Disposed within the interior volume of the housing is a spherical member. The spherical member is movable between a plurality of fixed positions through manipulation of the housing, specifically applying an inward force to the ends of the housing. Support elements are present on the housing and spherical member that are operable to couple to a device.

A fairing for a vehicle load bar includes an elongate blade and a connection assembly to couple the blade to the load bar. The connection assembly includes a joint having a ball disposed in a socket such that the ball can rotate within the socket. The connection assembly can include a pivot bracket coupled to the blade, the pivot bracket including the ball, and a pivot arm including the socket such that the ball of the pivot bracket is disposed in the socket.

A connection lock for prefabricated components includes an auxiliary part and a main part which are each provided with a fixing structure for connecting with a prefabricated component in an anchoring fit manner. The auxiliary part includes an auxiliary part body, an auxiliary part transmission structure, and a lock pin structure which is movably mounted to the auxiliary part body. The auxiliary part transmission structure is in transmission fit with the lock pin structure. The main part includes a main part body, a main part transmission structure, and a locking structure. An inserting channel fitted with the lock pin structure is formed in the main part body. The locking structure is adjustably mounted in the main part body. The main part transmission structure is in transmission fit with the locking structure. It is rapid and convenient to operate, and the construction efficiency is higher than traditional construction methods.
