Viewfinder for bow strings
View Patent ↗Viewfinder for bow strings, aimed to be connected to a bow string such that a user may look through it and obtain a precise shot, which comprises an elongated body with a through-hole defined between a front side and a rear side, wherein the hole further comprises a first sector, a second sector and a third sector, designed to prevent the reflections produced inside the hole by the light beams hitting it from the exterior from propagating to the user.
1. Viewfinder for bow strings, designed to be connected to a bow string such that a user may look through it and obtain a precise shot, which comprises an elongated body in the direction of an axial axis (EA), wherein said body, in turn, comprises:
an outer lateral surface,
a front side, aimed to be oriented towards a target,
a rear side, opposite to the front side, aimed to be oriented towards a user,
a through-hole between the front side and the rear side, defined by an inner lateral surface of the cylinder, and
a first groove defined on the outer lateral surface of the cylinder, co-axial with respect to the axial axis (EA), which is aimed to house the bow string, wherein the through-hole of the viewfinder further comprises:
a first sector that originates from the front side and comprises a first end, located on said front side, and a second, innermost end in the longitudinal direction, wherein the dimensions of the second end are smaller than those of the first end,
a second sector that originates from the rear side and comprises a third end, located on said rear side, and a fourth, innermost end in the longitudinal direction, wherein the dimensions of the fourth end are smaller than those of the third end, and
a third sector which is limited, respectively, by the second end of the first sector and the fourth end of the second sector, wherein the third sector comprises a lateral surface the dimensions whereof are greater than those of the second end and the fourth end,
in order to prevent the reflections produced inside the hole by the light beams hitting it from the exterior from propagating to the user.
2. Viewfinder for bow strings according to claim 1 , wherein the first sector, the second sector and the third sector of the hole are co-axial.
3. Viewfinder for bow strings according to claim 1 , wherein the first sector of the hole has the shape of a truncated cone.
4. Viewfinder for bow strings according to claim 1 , wherein the second sector of the hole has the shape of a truncated cone.
5. Viewfinder for bow strings according to claim 1 , wherein the third sector of the hole has an annular geometry.
6. Viewfinder for bow strings according to claim 1 , wherein it further incorporates at least a second groove defined on the outer lateral surface of the cylinder, which is aimed to house the bow string.
7. Viewfinder for bow strings according to claim 6 , wherein the orientation of the second groove is not perpendicular to the axial axis (EA) of the cylinder.
8. Viewfinder for bow strings according to claim 1 , wherein it further incorporates a shadow casting body, to further reduce the entry of light beams inside the hole.
9. Viewfinder for bow strings according to claim 8 , wherein the shadow casting body is located on the upper portion of the front side of the body, in order to prevent the entry of light beams that may hit the interior of the hole from above.
