ARCHERY SIGHT MOUNTING ASSEMBLY
An archery sight mounting assembly includes an elevation rail, elevation and windage assemblies for displacing an archery scope or aperture relative to the elevation rail, and a guide assembly connected with at least one of the elevation and windage assemblies. The guide assembly includes a pair of synthetic plastic gibs on either side of the assembly and a further gib beneath the assembly. The elevation and windage assemblies include locking assemblies, respectively, in line with a target to lock the assemblies in a fixed position. A mounting block assembly is removably connected with the windage assembly via a wedge locking connection. In addition, the mounting block assembly includes first, second and third axis devices for micro-adjusting the scope or aperture along three axes.
Archery sights are used by hunters and competition archers to increase the accuracy of a shot. The sights may be attached directly to a bow but are more typically mounted on a sight elevation rail which in turn is connected with an extension bar. A bow mount or mounting bracket is used to connect the extension bar with the bow. The extension bar is adjustable relative to the bow mount to properly position the sight aperture closer to or farther away from the archer.
The sight mounting assembly typically includes an elevation carriage mounted on the elevation rail for adjustment along a longitudinal axis and a windage carriage mounted on the elevation carriage for adjustment along an axis normal to the longitudinal axis. An aperture or scope is mounted on the windage carriage. By adjusting the elevation and windage carriages, an archer may position the aperture or scope in a preferred location.
For example, in archery competitions, targets may be arranged at a fixed distance from the archer or at multiple distances. Variable distance competitions require adjusting the position of the sight aperture along the elevation rail depending on the distance to the target. To accommodate the various distances, the elevation rail has an extended length for proper positioning of the sight aperture.
BRIEF DESCRIPTION OF THE PRIOR ARTArchery sight mounting devices that mount on a bow are known in the art. One such device is connected with an extension bar via suitable fasteners. In use, the extension bar generally extends horizontally and the archery sight apparatus extends vertically, with the sight being adjusted for elevation along the elevation bar. More particularly, the elevation carriage includes an elevation adjustment knob to operate an elevation drive assembly and the windage carriage includes a windage adjustment knob to operate a windage drive assembly.
While such a device normally operates satisfactorily, the mounting assembly is susceptible to excessive vibration between the windage and elevation carriages and between the elevation carriage and the elevation rail. Such vibrations have been addressed by providing a guide assembly including a pair of gibs at the sides of the elevation carriage between the elevation carriage and the elevation rail. While such a guide assembly operates satisfactorily, there is a need for an improved guide assembly which further limits vibrations.
Another drawback of prior sight mounting assemblies is that the degree of manual adjustment is limited owing to the structure of the elevation and windage drive assemblies. Accordingly, there is a need for an improved adjustment assembly which provides more precise positioning of the aperture and for an improved locking assembly for securing the windage and elevation carriages in a selected location.
SUMMARY OF THE INVENTIONAccordingly, it is a primary object of the invention to provide an archery sight mounting assembly including an elevation rail, an elevation carriage assembly slidably mounted on the elevation rail, a windage carriage assembly adjustably mounted on the elevation carriage assembly, and a guide assembly connected with one or both of the elevation and windage carriage assemblies. More particularly, the guide assembly includes first and second gibs arranged on opposite sides of the elevation and/or windage carriage assemblies and a third gib arranged beneath the bottom of the elevation and/or windage carriage assemblies. The third gib for the elevation carriage assembly is arranged between the elevation carriage assembly and the elevation rail and the third gib for the windage carriage assembly is arranged between the windage carriage assembly and the elevation carriage assembly.
The elevation carriage assembly further includes a keyway for accurate alignment of the elevation carriage assembly relative to the elevation rail in a first direction and a V-shape configuration for accurate alignment of the elevation carriage assembly relative to the elevation rail in a second direction normal to the first direction. A tension assembly is provided for the windage carriage assembly to lock and release the windage carriage assembly relative to the elevation carriage assembly. The tension assembly includes a lock lever which activates pressure movement of the tension assembly from tight to loose in the direction of a target to eliminate left and right arrow impact error from the locked to unlocked condition.
According to a preferred embodiment, the elevation carriage assembly further includes an elevation locking assembly to lock the elevation carriage assembly in a selected position on the elevation rail. The elevation locking assembly and the windage lock lever both activate tension movement aligned with the target.
According to a further object of the invention, the windage carriage assembly is displaceable along a first axis and a mounting block assembly is arranged on the windage carriage assembly for positioning a scope along second and third axes relative to the first axis. The mounting block assembly includes a first axis member, a second axis member rotatably connected with the first axis member, a third axis member rotatably connected with the second axis member, and a spring-biased adjustment assembly for adjusting the positions of the second and third axis members relative to the first axis member, respectively. Set screws connected with the second and third axis members are operable by the archer to provide micro-adjustment of the second and third axis members to desired positions along second and third axes, respectively, relative to the first axis.
According to yet another object of the invention, a connecting assembly is provided to removably connect the mounting block assembly with the windage carriage assembly. The connecting assembly includes a wedge containing a through-opening and a bolt arranged in the wedge through-opening and connected with a threaded opening in the windage carriage assembly. The bolt is operable to displace the wedge between lock and release positions in which the mounting block is pressed against and released from the windage carriage assembly.
Other objects and advantages of the disclosure will become apparent from a study of the following specification when viewed in the light of the accompanying drawing, in which:
The sight mounting assembly includes an elevation carriage assembly 6 mounted on the elevation rail and a windage carriage assembly 8 connected with the elevation carriage assembly. The elevation rail extends along a longitudinal axis and the elevation carriage assembly is displaced along the elevation rail by rotation of an elevation screw 10 having elevation knobs 12 at both ends. The windage carriage assembly is displaced relative to the elevation carriage assembly in a direction normal to the transverse axis of the elevation rail. An archery sight aperture (not shown) is connected with the windage carriage. The elevation and windage carriage assemblies are adjustable by an archer to adjust the position of the aperture for optimum performance.
The elevation carriage assembly 6 is shown in more detail in
The elevation carriage 14 contains a pair of spaced parallel support surfaces 28, 30 which are configured to receive first 32 and second 34 synthetic plastic gibs as will be discussed below. As shown in
As shown in
A tension assembly for the elevation carriage assembly will now be described. It includes the first, second and third gibs and the cam shaft. More particularly, the cam shaft 22 passes through the aligned upper openings 20 of the elevation yoke 16 and through a bore 42 in the lower portion of the elevation carriage as shown in
The cam shaft 22 has a generally cylindrical cam surface. When the cam shaft is rotated in opposite directions, the cam surface abuts against the elevation yoke to displace the yoke toward and away from the elevation carriage depending on the position of the cam surface. When the yoke is moved toward the elevation carriage by rotation of the cam shaft, the tension between the carriage and the yoke and the elevation bar is released. When the yoke is moved away from the elevation carriage, the carriage presses against the first, second and third gibs to increase the tension between the carriage and yoke and the elevation rail. The springs 26 between the elevation carriage and elevation yoke exert a constant internal pressure on the gibs in line with the target for accuracy and to deaden vibrations within the elevation carriage and elevation yoke.
A locking mechanism for the cam shaft is shown in
With the screw 46 loosened, the tension lever 45 can be rotated to set a stop position for the lock lever, limiting the amount of clockwise rotation of the lock lever. This allows the lock lever to rotate the cam shaft clockwise to the desired consistent minimum tension. The screw 46 is tightened to lock the tension lever in place and the consistent minimum tension is thus fixed when the lock lever is unlocked in the clockwise direction to make contact with the tension lever stop tab. With the lock lever rotated fully in the clockwise unlocking direction with the stop tab in contact with the tension lever peripheral edge portion, the compression applied by the yoke to the first, second and third gibs is also fixed to that chosen setting. The lock lever further compresses the tension to all the way tight when activated in the counterclockwise direction. The cam shaft is thereby rotated in the counterclockwise direction by the rib contact of the lock lever, thereby removing all slop in the gibs, resulting in the elevation carriage being locked in place.
A drive mechanism releasably connects the elevation carriage 14 with the elevation screw 10. Referring to
In the drive mechanism for the elevation carriage according to the invention, the nut 48 is pivotally connected with the elevation carriage 14 via journals 54 on opposite sides of the nut which are seated in recesses in the carriage. A projection 55 of the nut mates to a swivel nut link 56 which is connected between the carriage and the nut as shown in
As set forth above and as shown in
As shown in
Referring now to
A tension system is provided for the windage carriage to adjust the tension between windage carriage and the elevation carriage. The windage tension system includes the first 92, second 94 and third 100 windage gibs and a windage tension screw 110 (
As shown more particularly in
As shown in
As described above, the windage carriage is displaced in a direction normal to the longitudinal axis of the elevation rail. The direction of movement of the windage carriage is referred to hereinbelow as the first axis.
The multi-axis scope mounting block assembly includes a first axis member 116, a second axis member 118 rotatably connected with the first axis and a third axis member 120 rotatably connected with the second axis member. As noted above, the windage carriage is displaceable along a first axis. Since the first axis member is connected with the windage carriage, it thus moves with the carriage along the first axis. The second axis member is rotatable about a second axis normal to the first axis and the third axis member is rotatable about a third axis normal to the first and second axes.
The first, second, and third axes referenced herein are not to be confused with the manner in which archers adjust a sight. In practice, archers adjust a first axis at the connection between the elevation rail and the extension bar, thus adjusting the elevation rail to be vertical to the sky. Archers adjust the second axis by leveling the scope, i.e., tilting it up or down while the first axis is level to simultaneously achieve leveling the elevation rail vertically and the scope horizontally. Archers adjust the third axis by pushing the scope away or toward them to achieve level while tilting the bow forward and backward, when shooting up or downhill.
As shown in
The third axis member 120 is rotatably connected with the second axis member 118 in a manner similar to the connection between the second axis member and the first axis member. Thus, the third axis member includes a post or projection 120a which is configured to fit within a corresponding slot 118c in the second axis member as shown in
Micro-adjustment of the second axis member relative to the first axis member and the third axis member relative to the second axis member is accomplished via set screws and springs for the second and third axis members. These will be described with reference to
The slot 116a of the first axis member contains a pair of oppositely extending channels 116c and 116d as shown in
Similarly, the slot 118b of the second axis member 118 contains a pair of oppositely extending channels 118c and 118d as shown in
The set screws and springs of the first and second axis members are in constant contact with the posts of the second and third axis members, respectively. The spring-biased adjustment of the second and third axis members affords a higher degree of precision, i.e. a micro-adjustment, in positioning a scope or aperture than is possible with a manual adjustment of these members.
The multi-axis mounting block assembly is removably connected with the windage carriage via a wedge connection which will be described with reference to
The angular arrangement of the screw 140 and threaded opening 138 in the mounting block improves the accessibility of the knob of the screw for the archer for quick removal or connection of the mounting block assembly. Of course, the connection assembly would still operate sufficiently if the screw and threaded opening were arranged parallel to the vertical axis of the windage carriage.
Further assistance for properly locating the mounting block assembly on the windage carriage is provided by an additional location and connection assembly between the windage carriage and the base of the mounting block. In this regard, the windage carriage 66 contains a further opening 146 opposite the contoured surface 66a as shown in
While in accordance with the provisions of the patent statute, the preferred forms and embodiments of the invention have been illustrated and described, it will be apparent to those of ordinary skill in the art that various changes may be made without deviating from the inventive concepts set forth above.
