Abstract: A fastening mechanism is mounted on a suction cup including a pivotal ball in a receptacle and having surface recesses, a leg secured to the ball, and a channel open to both the external and the receptacle, the channel having an intermediate enlargement. The mechanism includes a shank in the channel and having an exposed end, a rod extended from the other end of the shank and inserted in the recess, a shoulder proximate the rod, and a resilient member compressed between the shoulder and an internal wall of the channel. Pulling the shank to clear the recess and compress the resilient member, pivoting the ball by rotating the leg until a predetermined angle thereof relative to the suction cup is obtained, and releasing the shank to cause the compressed resilient member to expand to push the shoulder will insert the rod in the adjusted recess and fasten the ball.

Abstract: A suction cup includes a resilient plate including a concave bottom and a threaded middle projecting post; a bell including a support pivotably secured in an upper receptacle, an annular flange on a lower end, an internal space open to both lateral sides, a nut in the space threadedly engaged with the middle projecting post; and a pressing member disposed inside bell bottom being in contact with the flange, the pressing member including bottom pressing elements. Placing the suction cup onto a surface and continuously turning the nut will draw both the plate and the bell toward the surface and draw the pressing member onto the plate until a vacuum in a cavity between the plate and the surface is created to adhere the plate to the surface. The pressing elements are ribs or teeth having arcuate or straight shape.

Abstract: Provided is a clamp for fastening a portable electronic device. The clamp comprises two spring biased sliding arms and a spring biased trigger member. Pushing the trigger member toward the body will move the shuttle member upward to unlock both arms for extending thereafter. In response to sandwiching the device between the arms releasing the trigger member will push the trigger member outward and the shuttle member downward respectively for locking the ridges. In a case of the device having its ports provided at one side or both sides thereof, two central, rectangular openings of the arms are adapted to allow the ports to dispose therein for causing no interference to a normal operation of the fastened device. A distance between both arms can be adjusted by sliding one arm toward or away from the other arm or sliding both arms toward or away from each other.

Abstract: Provided is a universal device comprising a main body including a plurality of connecting sections including an upper plate and a lower plate in which devices including a built-in speaker, a transceiver unit such as a piece of GPS equipment or a wireless transceiver, a swivel coupling assembly adapted to couple to a hands-free device, a cradle for holding a portable electronic device such as a cellular phone, a PDA, a Smart Phone having the features of cellular phone and PDA, and a Palmtop, and a communication unit are releasably coupled to the upper or the lower plate or formed thereon. The invention permits a user to selectively couple the portable electronic device and/or the hands-free device to the universal device for communicating therewith.
