Abstract: Described is an archery device for transmitting power aimed at transmitting power from at least one limb to at least one arrow using at least one cam which is operatively connected to two or more flexible, substantially inextensible elements, designed to withstand tensile stress (cables and strings or tracts thereof), simultaneously operating at least one string tract and several cable tracts, the latter, in different directions to each other, wherein the net radial moment is determined by the combination of tensions and directions of the elements connected to it. This increases the design freedom when positioning the cam and reduces the friction linked to its rotation against a support, if necessary, making it possible to do without a support, thereby eliminating friction and improving efficiency.

Abstract: The present disclosure relates to a device for firing a projectile. The device comprises a stock, at least two elastic members, two levers symmetrically arranged on opposite sides of the stock, a first flexible element connecting the two levers with each other and intended for pushing the projectile during the firing, and a loading arrangement for shifting the device from a rest condition to a loaded condition. The two levers are movable with respect to the stock between a first position when the device is in the rest condition and a second position when the device is in the loaded condition; the two levers are operatively connected with the at least two elastic members for correlating a movement of the two levers between said first and second positions to a variation of deformation of the at least two elastic members. and vice versa.

Abstract: A device (1) for launching a projectile, comprising: a stock (2); at least two bending members (10) associated to said stock (2) on opposite sides thereof; tensioning means (323) of said bending members (10), comprising at least two cams (323) arranged on opposite sides of the stock (2), each of which is pivoted at a respective first axis of rotation (33) and is associated to at least one corresponding bending member (10); pushing means (30) of said projectile apt to cooperate with said bending members (10) comprising at least two pushing arms (32) arranged on opposite sides of the stock (2) and connected to each other through a flexible pushing member (31) wherein each of said pushing arms (32) is pivoted at a respective axis of rotation (33) and is apt to support a portion of said flexible pushing member (31), each of said pushing arms (32) being operatively connected to a respective cam (323), wherein said device (1) further comprises a flexible force member (37) for commanding a rotation of a pushing arm

Abstract: Device for launching a projectile or a launch object in general, comprising: a stock having a longitudinal development direction between a rear or proximal end and a front or distal end; at least two bending members associated to said stock on opposite sides of it and having a preferential development direction, said bending members being apt to be subjected to bending in order to accumulate and supply energy usable to launch said projectile, and released in a rest condition; tensioning means of said bending members; pushing means of said projectile apt to cooperate with said bending members. Said tensioning means comprise at least two cams arranged on opposite sides of the stock, each of which is pivoted at a respective first axis of rotation and is associated to at least one corresponding bending member, so that an angular displacement of said cam around said first axis of rotation determines a bending action on said at least one corresponding bending member.
