Abstract

A crossbow has a prod in two parts, each of which is pivotally connected with the stock so that the prod parts can lie alongside the stock when the bow is not in use. When the bow is prepared for use, the prod parts are clamped in operative positions by a mechanism which includes a handle and which provides a substantial mechanical advantage to the operator.

Claims

1. A crossbow comprising a prod which is formed in two relatively movable parts, a stock having a fore-end portion, means for mounting said parts on the fore-end portion for swinging relative to the stock and relative to each other while remaining connected with the stock and a mechanism which includes:

(a) a single pressure member which acts on both of said prod parts to exert thereon force transmitted by said mechanism and

(b) a handle connected to said pressure member, said mechanism being for transmitting force with a mechanical advantage from the handle through the pressure member to the prod parts to swing the prod parts into respective positions relative to the stock, which positions are occupied when the bow is in use, and wherein the mechanical advantage provided by said mechanism increases during swinging of said prod parts of the prod into said positions.

2. A crossbow comprising a prod which is formed in two relatively movably parts, a stock having a fore-end portion, means for mounting said parts on the fore-end portion for swinging relative to the stock and relative to each other while remaining connected with the stock and a mechanism which includes:

(a) a handle connected with the stock by a pivot defining a pivot axis and

(b) element means which, during the use of the crossbow, acts on the handle radially of the pivot axis to transmit to the handle force which results from application to the prod parts of a bending load, said mechanism being for transmitting force with a mechanical advantage from the handle to the prod parts to swing the prod parts into respective positions relative to the stock, which positions are occupied when the bow is in use, and wherein the mechanical advantage provided by said mechanism increases during swinging of said parts of the prod into said positions, said prod parts swinging substantially in a common plane which is parallel to the pivot axis of the handle.
