DETAILED DESCRIPTION OF EMBODIMENTS

(9) Reference is now made to FIGS. 1A-1E, which illustrate a mounting platform 10 for mounting thereon a bicycle seat assembly, constructed and operative in accordance with a non-limiting embodiment of the present invention.

(10) The mounting platform 10 includes one or more bicycle seat post attachment members 12, which in the illustrated embodiment are a pair of rails 12 attached to side extensions 14. The mounting platform 10 includes a receiving member 16 for receiving thereon or therein a portion 18 of a bicycle seat, which in the illustrated embodiment, is a portion of a locking member 18, described more in detail hereinbelow. The receiving member 16 may be curved to complement the shape of this portion 18 of the bicycle seat.

(11) The mounting platform 10 includes a quick release locking mechanism 20, including and operated by, a quick release fastener 22. As is known in the art, quick release fastener 22 includes a lever 24 that has a cam 26 that pivots about a pivot 28 (FIG. 1B). Lever 24 is attached to a bolt 30, which is assembled to a locking lug 32 arranged to move and lock against a locking surface 34 (e.g., notch, groove, inclined surface, etc.) formed in the portion 18 of the bicycle seat (FIG. 8C). Pivoting the lever 24 towards the body of mounting platform 10 (downwards in the sense of FIG. 8A) pulls bolt 30 to a tightened position (that is, locking lug 32 moves towards and locks against locking surface 34). Conversely, pivoting lever 24 away from the body of mounting platform 10 (upwards in the sense of FIG. 8A) pushes bolt 30 to an untightened (released) position.

(12) It is noted that lever 24 has a relatively long circular motion between the tightened and released positions, whereas bolt 30 has a relatively short linear motion between these positions.

(13) Reference is now made to FIG. 2, which illustrates a bicycle 40 with a bicycle seat assembly 42. The bicycle seat assembly 42 is a combination of a bicycle seat 44 and bicycle locking assembly 46 mounted on the mounting platform 10 attached to a bicycle seat post 48. As seen in FIGS. 2A and 2B, the rails 12 are clamped or otherwise attached to clamp members 50 of bicycle seat post 48.

(14) FIG. 3 illustrates releasing bicycle seat 44 from mounting platform 10 by means of quick release fastener 22.

(15) FIGS. 4 and 5 illustrate bicycle seat 44 with a locking assembly 46. The locking assembly 46 includes a plurality of locking members 60, which are pivotally connected to one another by pivot links 62. In the illustrated embodiment, there are a total of six (6) locking members 60, but the embodiment is not limited to this number, and the embodiment can have just two locking members 60 or more than 6. Locking members 60 are preferably made of a steel alloy, hardened against cutting or other vandalistic forces (or any other suitable material). One of the locking members 60 may be fixedly or pivotally secured to the underside of bicycle seat 44. Another of the locking members 60 may be connected to a locking device, such as a lock 64, which may be a cylinder lock operated by a key (not shown) or may be another type of lock, such as but not limited to, a combination lock or RFID lock. Opening the lock 64 releases a lock insert member 66 (FIG. 5) mounted on the end of one of the locking members 60, so as to permit unfolding and stretching out the locking members 60. FIG. 4 illustrates the locked position, wherein the lock insert member has been re-inserted and locked into lock 64.

(16) Reference is now made to FIG. 6, which illustrates the bicycle seat 44 being used as a lock to lock bicycle 40 to an object 68 (such as a bicycle stand). FIG. 7 illustrates the mounting platform 10 without the bicycle seat attached thereto.
