US12372331 - Device for achieving frictionless linear movement in a single direction and stiffness in all other directions

The patent describes a device designed to achieve frictionless linear movement in one direction while providing stiffness in all other directions, specifically for use in firearms to mitigate recoil. It features a modular blade system that allows for controlled movement and stability, ensuring minimal error during operation by counteracting secondary movements.

Claim 1

1. A firearm having mounted a device achieving linear movement in single direction and stiffness in all other directions that comprises: the following attached to a first member symmetrically about a plane containing the single direction; at least two modules of blades, each blade having each a first end and a second end, the blades with equal spacing and shape, each module comprising a first set of blades and a second set of blades, where each set comprising at least two parallel blades; and where the first set of blades of each module are attached on the first member in said first end of the blades of said first set, and in the second end of the blades of said first set connected, via a spacer, to the second end of said second set of blades; the blades of the second set are attached to a second member, in the first end of the blades; the first set of blades of said at least two modules and the second set of blades of at least two modules mounted symmetrical about said plane containing the single direction; characterized in that in each module the second set of blades is arranged to counteract the movement of the first set of blades in a direction which is perpendicular to said single direction, to obtain relief of a secondary movement of said first set of blades; thereby allowing said first ends of the first set of blades and said first member to travel friction free in said single direction of linear motion relative to said second ends without rotation and as a consequence resulting in a direction of travel of said second ends of said first set of blades with a direction component perpendicular to said single direction, whereby, the movement in the single direction, or the movement perpendicular to the single direction, or a combination of the these movement components of the second ends of said second set of blades have a component of movement in the direction of travel of said first set of blades perpendicular to said single direction to allow each of the second set of blades to provide friction free relief of said first set of blades in the direction perpendicular to the single direction, maintaining constant angles and high stiffness in all directions but said single direction of travel of said first set of blades; comprising further a first member and a second member wherein the first member has an annular part, and the second member has an annular part configured close to the first member, the annular parts of the first member and of the second member having the same radius, and their centers on a straight line going through the same point and perpendicular to an X-Y-plane; wherein said first member is adapted to be mounted onto a first accessory and second member is adapted to be mounted onto a scope of a firearm, the number of said modules of blades is two or three, and if two the angle between two adjacent modules of blades is 180 degrees, and if three the angle between two adjacent modules of blades is 120 degrees; the firearm having the device mounted between a scope of the firearm and said first accessory. characterized in that in each module the second set of blades is arranged to counteract the movement of the first set of blades in a direction which is perpendicular to said single direction, to obtain relief of a secondary movement of said first set of blades; thereby allowing said first ends of the first set of blades and said first member to travel friction free in said single direction of linear motion relative to said second ends without rotation and as a consequence resulting in a direction of travel of said second ends of said first set of blades with a direction component perpendicular to said single direction, whereby, the movement in the single direction, or the movement perpendicular to the single direction, or a combination of the these movement components of the second ends of said second set of blades have a component of movement in the direction of travel of said first set of blades perpendicular to said single direction to allow each of the second set of blades to provide friction free relief of said first set of blades in the direction perpendicular to the single direction, maintaining constant angles and high stiffness in all directions but said single direction of travel of said first set of blades; comprising further a first member and a second member wherein the first member has an annular part, and the second member has an annular part configured close to the first member, the annular parts of the first member and of the second member having the same radius, and their centers on a straight line going through the same point and perpendicular to an X-Y-plane; wherein said first member is adapted to be mounted onto a first accessory and second member is adapted to be mounted onto a scope of a firearm, the number of said modules of blades is two or three, and if two the angle between two adjacent modules of blades is 180 degrees, and if three the angle between two adjacent modules of blades is 120 degrees; the firearm having the device mounted between a scope of the firearm and said first accessory.
