An adjustable archery training bow assembly includes a single resistance element and an adjustment mechanism that can be actuated by a user to vary the tension level in the resistance element for training purposes. The training bow also includes an integrated laser sight that allows the user to precisely aim at a target. The adjustable archery training bow is used to enhance the user's skills, such as his/her strength, stability and accuracy in delivering an arrow fired from a real, non-training bow to the target.

Levers with fulcrums and other linkages can be structured to provide motion in many different structural formations by making adjustments to the parameters of a mechanism such as this invention. Mechanisms with multiple levers working together in coordination and moving a fraction of the full actuation allows machines to be built more efficiently. The levers can be connected to each other in multiple configurations which allow for these machines to be built and programmed from how the levers are connected to each other. This invention is modular so building complex actuators is a simple procedure. The machine can be used as a mechanical actuator or a projectile launcher or a programmable moving mechanism where the programming is built in the structure. By using levers, and simple energy mechanisms to power this invention, the overall efficiency of some processes can be increased.

In some embodiments, an archery bow riser comprises a body defining a first end, a second end and a grip portion. The body defines a shooting axis and comprises a first portion and a second portion. The first portion comprises a metal and the second portion comprises carbon fibers. The first portion extends to a first side of the shooting axis and to a second side of the shooting axis, and the second portion extends to the first side of the shooting axis and to the second side of the shooting axis.

A device for launching a projectile along an intended flight trajectory includes a launching mechanism. The launching mechanism includes first and second pairs of supports supporting a launching cord. A projectile having a longitudinal axis is disposed in the launching cord in a launch position prior to launch such that the projectile's longitudinal axis is perpendicular to a plane in which the launching cord is disposed. As the projectile is launched by the launching mechanism, the projectile rotates such that the projectile's longitudinal axis is parallel to the plane in which the launching cord was disposed.

In some embodiments, an archery bow comprises a riser and a load balancing limb support assembly supported by the riser. The load balancing limb support assembly comprises a body comprising a first support portion and a second support portion. A limb assembly comprises a first limb portion and a second limb portion. The first limb portion is supported by the first support portion and the second limb portion is supported by the second support portion.

A firing system for a crossbow having an arrow rest extending along an arrow rest axis, the firing system having a right limb and a left limb, the right limb being pivotable about a right limb axis and the left limb being pivotable about a left limb axis, the firing system further including a right cam and a left cam, the right cam having a right bow string groove and being rotatable about a right cam axis, the left cam having a left bow string groove and being rotatable about a left cam axis, the firing system having a bow string extending between the right and left cams and extending within the right and left bow string grooves, the bow string positionable between an un-cocked condition and a cocked or full draw condition wherein movement of the bow string from the un-cocked condition toward the cocked condition moves the right and left cams toward each other and pivots the right and left limbs about the right and left limbs axes respectively, the firing system further including a power assembly having a power cable and a spring assembly, the power cable having a forward end operably joined to the right and left limbs and a rear end operably joined to the spring assembly, the spring assembly having a power spring extending along a power spring axis between a first spring end and a second spring end and having a central spring opening, the power spring being below the arrow rest, the power cable extending through the central spring opening from the first spring end toward the second spring end, the rear end of the power cable being operably joined relative to the second spring end of the power spring, moving the bow string from the un-cocked condition to the cocked condition causing the right and left limbs to the pull forward end of the power cable forwardly wherein the operable engagement with the second spring end compressing the power spring by pulling the second spring end toward the first spring end to produce the shooting force to propel the archery arrow.

In some embodiments, an archery bow comprises a riser, a limb member and a support member. The limb member is supported by the riser at a first location. The limb member supports an axle at a second location. The support member is supported by the riser and arranged to support the limb member. The support member contacts the limb member at a contact location. The contact location is oriented between the first location and the second location along the length of the limb member.

A bow having a high throw weight and a low draw weight. The bow has an operative riser adapted to cause pivotal movement of an upper or lower limb. The operative riser includes a first end section connected to a first limb, a second end section connected to a second limb, and a central section connected between the first and second end sections, the first end section being fixedly connected to the central section and the second end section being pivotally connected to the central section. An actuating means is disposed within the central section to physically engage the second end section. A triggering means is connected to the actuating means to operably engage the actuating means and cause pivotal movement of the second limb. The pivotal movement changes a length between the distal ends of the limbs thus changing a draw or throw weight of the archery bow.
