Patent Application
20200124377
This invention relates generally to shooting devices, such as devices that can launch a projectile.
Multiple types of shooting devices are generally known in the art. A firearm can be used to launch a bullet, for example via expanding gasses provided by a chemical propellant. Bows can be used to launch arrows, for example by drawing a bowstring to store energy in the bow, then releasing the bowstring to launch an arrow.
Shooting devices are typically aimed by a user prior to the launching of the projectile, with the intention of the projectile traveling to a desired aiming point.
Instability during aiming can contribute to inaccuracy.
There remains a need for shooting devices and accessories having novel designs that can contribute to increased accuracy.
All US patents and applications and all other published documents mentioned anywhere in this application are incorporated herein by reference in their entirety.

For the purposes of this disclosure, like reference numerals in the figures shall refer to like features unless otherwise indicated.
In some embodiments, the first portion 20 is configured for attachment to a shooting device. In some embodiments, a shooting device supports the first portion 20 and the first portion 20 supports the second portion 30. In some embodiments, the grip 10 comprises a cavity 18 arranged to engage and contact a portion of a shooting device. In some embodiments, the cavity 18 is configured for attachment to a picatinny rail, for example comprising a hexagonal or modified-dovetail cross-sectional shape. In some embodiments, the cavity 18 is at least partially defined by a surface of a connector 19 that is attachable to the body of the first portion 20, for example by a fastener such as a screw.
In some embodiments, the second portion 30 is configured to be contacted by a hand. In some embodiments, the second portion 30 comprises a contacting surface 31 comprising a peak 32 and a valley 34. In some embodiments, the contacting surface 31 is configured such that the palm of a shooter's hand contacts the peak 32 and the thenar webspace of the shooter's hand contacts the valley 34.
In some embodiments, the second portion 30 is biased to the first position 46 and will assume the first position 46 when no external forces are applied. When a force F is applied to the second portion 30, the second portion 30 can travel towards the second position 48. In some embodiments, the second position 48 represents an end of the travel of the second portion 30.
In some embodiments, a biasing member 16 comprises a spring. In some embodiments, the biasing member 16 comprises a coil spring. In some embodiments, the biasing member 16 is compressed as the second portion 30 moves with respect to the first portion 20. In some embodiments, the strength of the biasing member 16 is selected to provide a desired amount of movement in the grip 10 in response to the levels of force applied to the grip 10 by a user.
In some embodiments, the first portion 20 comprises a seat 24 arranged to engage and anchor the biasing member 16. In some embodiments, the second portion 30 comprises a seat 24. A seat 24 can have any suitable configuration. In some embodiments, a seat 24 comprises a recess, blind hole or cavity. In some embodiments, a seat 24 comprises a post.
A biasing member 16 can have any suitable strength characteristics. In some embodiments, a biasing member 16 comprises a constant spring rate. In some embodiments, a biasing member 16 comprises a variable spring rate.
In some embodiments, a pin 38 comprises a connector that engages the first portion 20 and the second portion 30. In some embodiments, the pin 38 engages apertures 27 provided in the first portion 20. In some embodiments, the pin 38 engages apertures 37 provided in the second portion 30.
In some embodiments, at least one of the first or second portion 20, 30 comprises a stop 39, and the other portion 20, 30 comprises an interfering surface 29. In some embodiments, the stop 39 contacts the interfering surface 39 and limits relative movement between the portions 20, 30. As shown in
In some embodiments, the grip 10 comprises a recess 40 located adjacent to the stop 39. In some embodiments, the recess 40 provides clearance for the interfering surface 29. In some embodiments, as the second portion 30 moves with respect to the first portion 30 and travels toward the second position 48, the interfering surface 29 becomes positioned in the valley 40. In some embodiments, the stop 39 is located opposite the pin 38. In some embodiments, the stop 39 and the pin apertures 37 are provided on opposite ends of the second portion 30.
In some embodiments, the grip 10 comprises a second stop 59 and a second interfering surface 49. In some embodiments, the second stop 59 and second interfering surface 49 are associated with a second end of travel of the second portion 30 with respect to the first portion 20. In some embodiments, the second stop 59 contacts the second interfering surface 49 and prevents further movement when the second portion 30 is in the second position 48.
In some embodiments, a shooting device 8 comprises a rear grip 64 located adjacent to the trigger 62. In some embodiments, a grip 10 is attached to the shooting device 8. In some embodiments, the shooting device 8 comprises a picatinny rail 68, and the grip 10 is attached to the picatinny rail 68. In some embodiments, the grip 10 comprises a foregrip that is attached to the shooting device 8 at a location forward of the trigger 62.
In some embodiments, the shooting device 8 comprises a stock 66 and a butt 67. In some embodiments, the butt 67 is arranged to contact the shoulder of a person using the shooting device 8.
In some embodiments, a force F applied to the contacting surface 31 of the grip 10 will cause the second portion 30 to move with respect to the first portion 20. In some embodiments, the first portion 20 is fixedly attached to the shooting device 8, and the force F causes the second portion 30 to move with respect to the shooting device 8. In some embodiments, the shooter can also apply a reacting force R to another portion of the shooting device 8. In some embodiments, a reacting force R is applied to the rear grip 64. When a shooter applies counteracting forces such as the force F and the reacting force R to the shooting device 8, accuracy may be improved. For example, an amount of “float” present during aiming can be reduced upon the application of counteracting forces.
In some embodiments, a shooting device 8 defines a shooting axis and a forward shooting vector. In some embodiments, a force F applied to the contacting surface 31 is arranged in the direction of the forward shooting vector (e.g. parallel to the forward shooting vector).
In some embodiments, the amount of movement of the grip 10 in response to an applied force F can be adjusted to better suit the user. In some embodiments, different biasing members 16 can be used that provide different movement characteristics. A biasing member 16 with a higher spring rate can move less in response to a predetermined force F than a biasing member with a lower spring. In some embodiments, multiple biasing members 16 are provided for use in the grip 10. In some embodiments, a grip 10 can comprise an adjustment mechanism to move an at-rest location of the biasing member 16. For example, in some embodiments, an adjustment mechanism comprises a seat 24 for the basing member 16. In some embodiments, the adjustment mechanism allow the specific location of the seat 24 to be adjusted with respect to the body portion 20, 30 that supports the sear 25. In some embodiments, a threaded adjustment mechanism can be used to move the seat 24. This can be used to continuously adjust the spring force of the grip 10 without changing the biasing member 16.
In some embodiments, the grip 10 comprises a first portion 20 arranged to move with respect to a second portion 30, and the first portion 20 comprises an integral portion of the shooting device 8. In some embodiments, the first portion 20 comprises a portion of the riser 12.
