DETAILED DESCRIPTION OF DRAWINGS

(10) The present invention discloses a unique cocking sled. In a preferred embodiment, the cocking sled 7 having a body, generally U shaped. The sled body is a structural element having an upper surface, a guide boss 7c, an anti dry-fire de-activation boss 7e, a string retainment track 7a, a flexible member journal 7f, a barrel engagement surface 17, and an upper string engagement surface 7d. The bowstring retainment track 7a has a first half-track 15 that is on a first side of the longitudinal center of the cocking sled, also known as the first leg 13, and the second half-track 16 is on a second side of the longitudinal center of the sled also known as the second leg 14. The barrel engagement surface 17 is the lower surface of the structural element that joins the first leg 13 and first half-track 15 with the second leg 14 and second half-track 16. The cocking sled 7 is engage-able with a bowstring 100 in an uncocked or at rest position, and when the bowstring 100 is in the cocked position. The cocking sled 7 may have multiple means for moving the sled 7 from a crossbow-uncocked position to a crossbow-cocked position. One of these means being a flexible member 3 attached too, or coupled with the cocking sled 7. Handles 18 or the like may be provided at the ends of the flexible member 3, and the cocking sled 7 may be moved manually by pulling, as prior art has been done with rope cockers, or in a direct-pull fashion.

(11) The cocking sled 7 is removable from the bowstring 100 after the crossbow 1 is cocked. Due to the cocking sled 7 having no protrusion below the upper string engagement surface 7d, removal of the cocking sled 7 is very easy after the crossbow is cocked.

(12) In an alternate embodiment, a manual or powered mechanical device (mopm device) 11 coupled with a spool (not shown) is used for winding or unwinding the flexible member 3, allowing or causing movement of the cocking sled 7 from a first proximal position, which is parked adjacent the mopm device 11, to a second distal position to engage and retain the bowstring 100 and back to a third position wherein the cocking sled positions the bowstring 100 with a string latch (not shown), then forward to a fourth position which is forward the third position a distance sufficient to disengage the cocking sled 7 from the bowstring 100 when the bowstring 100 is in the cocked position and retained by the latch, and back to the first proximal position parked adjacent the mopm device 11. The upper string engagement surface 7d of the cocking sled 7 is adjacent the string retainment track 7a and the upper tangent point of the bowstring 100.

(13) For sake of clarity, when the barrel or frame 260 of the crossbow is level, it is on a first plane. The cocking sled 7 has a barrel engagement surface 17, wherein this barrel engagement surface 17 engages the barrel or frame upper engagement surface 260a. The cocking sled 7 has an upper string engagement surface 7d above the barrel or frame 260. The bowstring 100 engages the bowstring retainment track 7a of the cocking sled 7 and the barrel or frame upper engagement surface 260a. The cocking sled 7 is manufactured such that when the barrel engagement surface 17 of the cocking sled 7 is parallel and engaged with the upper engagement surface of the barrel or frame 260a, and the user moves the cocking sled 7 from the second position to the third position without tipping the rear of the cocking sled 7 in a downward direction, the upper string engagement surface 7d of the cocking sled 7 is never below the barrel or frame upper engagement surface 260a.

(14) Alternately, the cocking sled 7 may tip as it is being moved from the second position to the third position, such tipping does not result in adverse conditions as relates to the use of the invention. A cocking sled of the present invention has no interference when disengaging or re-engaging with the bowstring, as there is no protrusion projecting downward below the upper string engagement surface of the sled.

(15) Multiple embodiments of the invention wherein the sled is movable manually by a rope, as in a rope cocker 5 which reduces draw force by half, as shown in FIG. 1A, a mid-segment 3a of the flexible member 3 is positioned adjacent in a proximal receiver on the crossbow (not shown) in order to create a pulley effect. Another embodiment integrates components to create what is known in the art as a direct-pull cocker 6 which requires full draw force. When used as a direct-pull type cocking device as shown in FIG. 1B, the flexible member 3 may be replaced with any object or material sufficient to join the cocking sled body 7 with a handle 18 or the like. In yet another embodiment, the use of an mopm device, or any other method known in the art of moving a cocking sled to cock and or de-cock a crossbow. Though the present invention has been characterized as generally U shaped, any shape that allows for the function of retainment a bowstring to complete the process of cocking and or unlocking a crossbow as prescribed shall be considered an alternate embodiment. Further, the present invention may be utilized with projectile launching devices that are known as rail-less in design.

(16) It is to be understood that though the specifications described and the drawing illustrated the preferred embodiments of the invention, alterations in shape, size, type of material and process of manufacture do not fall outside the scope of the invention.
