(32) The mount 20 comprises: a locking cap 30 having a protrusion 32; a rotatable cap 40 having a tab groove 45 wherein the rotatable cap 40 is rotatable with respect to the locking cap 30; a biased switch 50 having a first tab 55. The first tab 55 is biased toward the rotatable cap 40, and thus, it can be released into the tab groove 45 of the rotatable cap 40. The mount 20 is attachable to the attachment portion 10 by inserting the protrusion 32 of the locking cap 30 into the groove 14 of the attachment portion 10 and rotating the attachment portion 10 or the locking cap 30 with respect to each other. More precisely, the protrusion 32 of the locking cap 30 passes the groove 14 of the attachment portion 10 and rests in the hollow cavity of the attachment portion 10, and then, the locking cap 30 rotates within the hollow cavity of the attachment portion 10 until the protrusion 32 of the locking cap 30 is at least partially aligned with the protrusion 12 of the attachment portion 10 in order to prevent the locking cap 30 from being dislodged from the attachment portion 10.

(33) After the protrusion 32 of the locking cap 30 is inserted into the groove 14 of the attachment portion 10 and passes the groove 14 to rest in the cavity of the attachment portion 10, the protrusion 42 of the rotatable cap 40 is received in the groove 14 of the attachment portion 10. Since the protrusion 42 of the rotatable cap 40 is received or fits in the groove 14 of the attachment portion 10, when rotating the attachment portion 10 or the locking cap 30 with respect to each other, the rotatable cap 40 rotates together with the attachment portion 10 with respect to the locking cap 30, thereby allowing the tab 55 of the biased switch 50 to be released into the tab groove 45 of the rotatable cap 40 in order to prevent rotation of the rotatable cap 40 and removal of the locking cap 30 from the attachment portion 10. The biased switch 50 is biased toward the rotatable cap 40 by a spring or any other means known in the art.

(34) For attaching and detaching the attachment portion 10 to or from the mount 20, the protrusions 32 of the locking cap 30 are aligned with the protrusions 42 of the rotatable cap 40, and then, those protrusions 32, 42 are aligned with the grooves 14 of the attachment portion 10 to be received therein. In FIG. 5, the protrusions 32 of the locking cap 30 are inserted into the grooves 14 of the attachment portion 10, pass the grooves 14, and rest in the cavity of the attachment portion 10 whereas the protrusions 42 of the rotatable cap 40 is received in the grooves 14 of the attachment portion 10. Since the protrusions 42 of the rotatable cap 40 is stuck in the grooves 14 of the attachment portion 10, the rotatable cap 40 rotates together with the attachment portion 10 until the first tab 55 of the biased switch 50 is released into the tab groove 45 of the rotatable cap 40 in order to prevent further rotation of the rotatable cap 40 as in FIG. 5. Since the rotatable cap 40 cannot rotate, the locking cap 30 is locked to the attachment portion 10 and cannot be removed or dislodged from the attachment portion 10. The attachment portion 10 can be rotated clockwise or counter-clockwise.

(35) The mount 20 may further comprise a base 60 which is fixedly attached to the locking cap 30. The locking cap 30 can be fixedly attached to the locking cap 30 by male/female thread coupling, by a bolt, or by bolt/nut coupling, or by any other means known in the art. The rotatable cap 40 is rotatable with respect to the locking cap 30 and the base 60, and the base 60 is constructed to be attachable to a bicycle or a vehicle.

(43) Before the inserting, the tab grooves 45 of the rotatable cap 40 are aligned with the grooves 34 of the locking cap 30 whereas after the rotating, the tab grooves 45 of the rotatable cap 40 are aligned with the protrusions 32 of the locking cap 30.

(44) FIGS. 6 and 7 show alternative embodiments of the biased switch 50 and the tab grooves 45 of the rotatable cap 40. FIG. 6 shows one embodiment and FIG. 7 shows another embodiment of the biased switch.

(45) As in FIG. 6, tab grooves 45 are formed on the bottom of the rotatable cap 40, and the tab 55 of the biased switch 50 is biased toward the rotatable cap 40 and constructed to be received in the tab groove 45 to prevent rotation of the rotatable cap 40. Furthermore, beveled grooves 47 are formed on the bottom of the rotatable cap 40 wherein the tab grooves 45 and the beveled grooves 47 are alternately disposed in a circle as in FIG. 6. Rotation of the rotatable cap 40 pushes the tab 55 of the biased switch 50 in the beveled groove 47 away from the rotatable cap 40 and then, the tab 55 is released into the tab groove 45 to prevent further rotation of the rotatable cap 40. The tab 55 may be pushed out of the tab groove 45 and the rotatable cap 40 may be rotated in order to allow the tab 55 to be released into the beveled groove 47.

(46) Alternatively, the biased switch 50 may be a lever resting on a pivot and the pivot has a spring to bias the tab 55 toward the rotatable cap 40. The pivot or hinge is spring-loaded to bias the switch 50 toward the rotatable cap 40.

(47) As in FIG. 7, tab grooves 45 and beveled grooves 47 may be alternately disposed on an outer-circumferential surface of the rotatable cap 40. The tab 55 of the biased switch 50 is biased toward the rotatable cap 40 and constructed to be received in the tab groove 45 to prevent rotation of the rotatable cap 40. Rotation of the rotatable cap 40 pushes the tab 55 of the biased switch 50 in the beveled groove 47 away from the rotatable cap 40 and then, the tab 55 is released into the tab groove 45 to prevent further rotation of the rotatable cap 40. The tab 55 may be pushed out of the tab groove 45 and the rotatable cap 40 may be rotated in order to allow the tab 55 to be released into the beveled groove 47.
