<p>A crossbow comprises a stock (10) including a fore-end portion (12) having a guide surface for a bolt, and a butt portion (14) pivotally connected thereto, and a cocking means which includes a linkage (24, 27) connected between said butt portion and a hook member (25) which engages the bow-string (13) to draw it rearwardly to engage with a releasable catch (17) for holding the bow-string in its cocked position. The hook member (25) is pivotally connected to said linkage and includes guide elements (26a, 34) which engage a guide track (33) extending along the fore-end portion so that the hook member (25) is maintained in a substantially unvarying orientation relative to the bow-string (13) as it is drawn towards the releasable catch (17). The hook member comprises two transversely spaces hooks (31) each of which includes a roller (35) whereby the bow-string is engaged, and the guide track (33) includes a forward portion (33a) which extends away from the path of the bolt when fired, so to retract the hook member out of the path of the bolt and bow-string before the bolt is fired.</p> |
