The vast array of device accessories available today is a result of ongoing technological innovation, consumer demand for customization, and the need for adding functionality after devices have been purchased. Take for example, the archery bow. A modern bow has many accessories that make up the system or kit. Accessories attach to the bow structure on any surface or side of the bow, which can include the handle (or riser), limbs, and cams. Accessories are generally attached to any surface or feature integral (or monolithic) to the bow handle. These features range from a variety of threaded holes, to more complex geometries that may include vertical or horizontal dovetail shapes. Archers use a variety of arrow configurations to optimize the arrows' speed, diameter and stability for a particular discipline of archery (e.g., hunting, target, etc.). As a result, the accessories that provide stability, sighting references, arrow support and arrow storage need to be tailored for each arrow configuration.
Accessories are not limited to just the aforementioned. Accessories for bows can also include, but are not limited to, real-time kinematic training aids, active data measurement devices, lights, wind indicators, cameras, cell phones, laser range finders and chronographs.
Accessories are also commonplace in other fields of endeavor (cameras and video equipment, hiking, camping and other outdoor equipment, etc.). The list of accessories and their application is endless, but the need remains for a quick and repeatable locking mechanism from which any accessory can be attached or detached or interchanges.
A need exists for a quick and repeatable mounting mechanism that enables an user to switch between device configurations and various accessories. Example accessories for bow systems include, but are not limited to, sights, scopes, pins, arrow rests, stabilizer, stabilizer weights and dampeners, quivers. Other accessories for bow systems and other devices are too numerous to name, but can also benefit from the quick mount system disclosed herein.
A quick mount system with quick locking and detachment mechanism is disclosed herein, as it may be provided for attaching and detaching bow and other accessories to a mounting structure. An example of the quick mount system includes a first interfacing component having a receiving element formed therein. The example quick mount system also includes a second interfacing component having a coupler assembly configured to mate with the receiving element in a first position. The coupler assembly rotates into an engagement position relative to the first interfacing component. A magnetic coupler maintains the first interfacing component and the second interfacing component in the engagement position to attach the accessory to the mounting structure.
In an example, the quick mount system also includes an interference interface between the first interfacing component and the second interfacing component. The interference interface limits rotation of the first interfacing component and the second interfacing component relative to each other. The interference interface may include at least one ramp formed on the receiving element formed in the first interfacing component, and at least one corresponding ramp on the coupler assembly of the second interfacing component.
In an example, the relative rotational position between two components of the mechanism is angularly located and fixed by complementary ramp features. This rotational locking mechanism locates the two components relative to each other in the vertical and horizontal axes simultaneously. An additional coupling force secures the two components together (e.g., through compression or magnetically). To decouple the components, an external torque is applied to one component relative to the other.
Before continuing, it is noted that as used herein, the terms “includes” and “including” mean, but is not limited to, “includes” or “including” and “includes at least” or “including at least.” The term “based on” means “based on” and “based at least in part on.”
It is also noted that the examples described herein are provided for purposes of illustration, and are not intended to be limiting. The device is not limited to any particular end-use or category of devices. While described herein primarily as it may be implemented with bow systems for archery, it is understood that the quick mount system may be implemented with any of a wide variety of different accessories in any field of endeavor not limited to archery or bow systems. Other devices and/or device configurations may be utilized to carry out the operations described herein.
The operations shown and described herein are provided to illustrate example implementations. It is noted that the operations are not limited to the ordering shown. Still other operations may also be implemented.
A quick mount system is disclosed herein as it may be implemented to attach and detach bow and other accessories, such as a weight 20, arrow rest 30 or sight 40 to a structure 3 or through an intermediate structure 5 connected to the mounting structure 3. Examples of other bow accessories can include, but are not limited to, lights, cameras, containers and quivers (not shown). The quick mount system 100 may also be implemented for other types of accessories and is not limited to the field of archery.
A quick mount system for removably attaching an accessory to a mounting structure is disclosed, including a first interfacing component having a receiving element formed therein. A second interfacing component having a coupler assembly is configured to mate with the receiving element in a first position, and rotate into an engagement position relative to the first interfacing component. A magnetic coupler maintains the first interfacing component and the second interfacing component in the engagement position to attach the accessory to the mounting structure.
The two components 110 and 130 are connected by inserting the protrusion 112 into the cavity 132, and are rotated along the mounting axis 14 relative to one another. An example protrusion 112 of the male component 110 has at least one circular geometric ramp 116 that, when rotated (or twisted) about the mating axis 14, forces the complementary ramp 136 of the cavity 132 of the female component 130 to interfere (see reference 165 in
In an example, an interference interface between the first interfacing component and the second interfacing component limits rotation of the first interfacing component and the second interfacing component relative to each other. The interference interface can include at least one ramp formed on the receiving element formed in the first interfacing component. At least one corresponding ramp can be provided on the coupler assembly of the second interfacing component.
In an example, the ramp formed on the receiving element mates with the corresponding ramp on the coupler assembly, and tightens together as the first interfacing component is rotated in a first direction relative to the second interfacing component. The ramp formed on the receiving element mates with the at least one corresponding ramp on the coupler assembly, and loosens from one another as the first interfacing component is rotated in a second direction opposite the first direction relative to the second interfacing component.
In an example, the ramp formed on the receiving element can have a circular shape such that relative rotation between the first interfacing component and the second interfacing component axially align while limiting the rotation to less than one relative revolution.
In an example, the corresponding ramp formed on the coupler assembly has an elliptical shape such that relative rotation between the first interfacing component and the second interfacing component taxially align while limiting the rotation to less than one relative revolution.
In an example, the circular shape of the receiving element has a diameter that is less than the diameter of the ellipse shape of the coupler assembly.
An example protrusion 110 has an oblong elliptical shaped ramp feature 116 with an angle (see reference 117 in
In an example, the first end 139 of the ramp has a different distance from the center of rotation compared to the second end 140 of the ramp, and matches the male ramp geometry. The female ramp 136 outer diameter is slightly larger than the male ramp 116 to allow for engagement prior to rotation. In an example, a plurality or multiple (more than one) complementary mating ramps 116 and 136 may be provided.
The protrusion 112 and cavity 132 may also be implemented in any intermediate component 150, allowing the accessory to be positioned further away from the mounting structures 3 and 5. These intermediate components 152, 154 and 156 work together as a system with varying axial dimensions (see components 158a, 158b in
To maintain the two components 110 and 130 in a mated rotational orientation, an external locking force is applied relative to the two components that increases the coupling force between the two components. To overcome this locking force, a greater unlocking force/torque is required to overcome the locking force. The locking force can be generated with a secondary locking mechanism, such as, but not limited to, set screws (e.g., provided in opening 162 in
In an example the dipole magnets 155 are placed on each component 110 and 130 in the same angular orientation. When the ramps intersect during rotation, the magnet dipoles attracting force holds the two components 110 and 130 in place rotationally.
The magnets 155 may be located on a diameter greater than the protrusion ramp 114 diameter, but less than the outer diameter of the locking mechanism on both components 110 and 130. The further away the magnets 155 are from the center of rotation 14, the larger the coupling force becomes, thereby increasing the torque required to decouple the two components 110 and 130 from one another.
An example includes a magnetic force produced by two or more dipole magnets 155, or by one or more multi-pole magnets 160. In any event, there is at least one magnet on each component 110 and 130. When the two components 110 and 130 have been rotated and the mating ramp surfaces 116 and 136 intersect, the magnet dipole magnetic fields moment axes 157 are rotationally aligned such that the axis of each magnet's magnetic field are mostly co-axially aligned with one another. This results in a rotational holding force that requires an external shear force to be applied to overcome the co-aligned magnets 155 or 160.
The magnetic poles of each magnet in each component are configured to magnetically attract (North-to-South, South-to-North), resulting in a force that holds the two components 110 and 130 relative to one another when at their physical limit of rotation by the ramp features 116 and 136. As the components 110 and 130 are rotated, the mating ramp surfaces 116 and 136 intersect, and an attractive or repulsive magnetic force is applied to hold the dovetail features together. These magnets can be affixed to the components with the use of, but not limited to, mechanical press fits, adhesives, retaining rings, splines or fasteners.
When multipole magnets 160 are implemented, these can be mounted centrally along the axis of rotation 14. There are several configurations for mounting the poly magnet in the receiving cavity of the components 110, 130 or 150. In an example, an asymmetric feature of a flat 240 receives a radial fastener to impart a holding force to push the magnet 160 into the side of the cavity. A partial circular feature 242 is provided in conjunction with a pin 244 that locates the magnet in the cavity as the cavity has a matching partial circular feature to 242. Another example includes a snap ring 226 that provides a physical limit to retain the magnet in the cavity. An additional example includes multiple forced detents 228 that are generated by deforming the edge of the cavity, such that a portion of the cavity material yields to forcibly hold the magnet in position. Any of these techniques serve to rotationally orient the magnet dipole axes with the asymmetric feature to align with lock position 165.
In another example, generating an axial holding force is with a ball spring detent mechanism 200.
In another example of increased rotational coupling force, the force is imparted through a compliant disc 300 rotationally located at the base of the male component 110.
In an example, a disc 302 is located between the base of protrusion 110 and the accessory 20. The protrusion 110 and disc 302 are attached to accessory 20 via a fastener 318. The accessory may have a complementary shaped cavity 316 to receive and angularly locate the disc 302 and ramped protrusion 110. The protrusion 110 has a minimum of one circular ramp 320, where the angle is less than 90 degrees. The female component 130 has a cavity 132 and a minimum of one radial protrusion 322 with an integral circular ramp 324, where the angle is less than 90 degrees and complementary to ramp 320.
When protrusion 110 and female component 130 are mated and rotated relative to one another, protrusion 322 rotates and intersects the leading edge of disc 302. This serves as a cam/lobe that, when rotated relative to the male component 110, the lobe intersects the protrusion ramp 312. As the rotation continues, protrusion 322 yields the disc by applying a radial force to the disc protrusion 310. The void 326 in disc 302 enables the protrusion 310 to yield, and allows the component protrusion 322 to continue to rotate to intersect with the trailing ramp 314 of the disc 302.
In an example, the angular rotation is limited by ramps 320 and 324 intersecting. This point of limited rotation 330 angularly locates protrusion 322 on the trailing ramp 314. By doing so, the yielded protrusion 310 is relaxed back to its natural circular shape, resulting in an outward radial force. As the force is applied to the trailing ramp 314, a tangential rotational force is applied to the protrusion, resulting in a continuous locking force. This locking force keeps the complementary ramps 320 and 324 constantly engaged.
To overcome this holding force, a torque is applied by twisting one component relative to the other, which rotates protrusion 322 up the protrusion trailing ramp 314, recompressing the disc protrusion 310, and the cam 322 ultimately is relieved of the bias force generated by the disc 302 relaxing back to its natural circular shape.
In this example, the locking arm 600 is mounted on a pin 602 on either of the first or second interfacing components to pivot about the pin 602 between an unlocked position and a locked position. The secondary locking mechanism also includes a spring for biasing the locking arm in the locked position. The arm is manually operable to pivot about the pin against a biasing force of the spring to release the arm from the locked position. There is at least one tooth (and a plurality of teeth are shown) or engagement mechanism on the arm to ratchet-engage with a plurality of teeth on the coupler assembly. The arm 600 automatically pivots into the unlocked position as the first and second interfacing components rotate relative to one another into the engagement position. The arm 600 automatically pivots into the locked position after the first and second interfacing components are in the engagement position.
The secondary forces are generated by further increasing the coupling force between components 110 and 130, e.g., by a fastener, or by other means such as, but not limited to, a cam locking system (not shown).
In the case of a more permanent locking mechanism, a set screw featuring external threads is mated in a drilled and tapped hole featuring internal threads. As this set screw assembly is tightened, the mating ramps 116 and 136 features are forced together rigidly. With this option, the user can choose to mate the two components of the locking mechanism together temporarily or permanently.
A centering feature 126 on the male component protrusion 112 includes an extruded cylindrical shape that mates with the tangent edges of the female cavity 132, receiving cylindrical shape 128. This allows for easier rotation of the two components.
To increase torque, a radial hole 500 is located on the outer surface of each component. A long cylindrical tool such as, but not limited to, an Allen wrench 502 can be inserted into the hole to increase the moment arm that the shear force is applied. This allows for more leverage to be applied to the system in the case of components being difficult to separate.
Arrow rests 30 and sights 40 accessories are generally mounted on the outward facing side of a bow handle 3, but have also been mounted to the forward and aft facing surfaces of a bow handle 3. In the case of an arrow rest 30, the need to quickly exchange one arrow rest optimized for a small diameter arrow for outdoor archery with a different arrow rest optimized for a larger diameter arrow for indoor or 3D archery, allows the archer to use one bow system 1 for several different archery applications. In an example, the male component 110 of the quick mount system 100 can be mounted to the aft facing surface of a bow handle 3, and the female component 130 of the locking mechanism incorporates the arrow rest mount adapter 164 (e.g., vertical Picatinny rail). In this example, the arrow rest mount 164 is integral (monolithic or one-piece) to the female component 130. The arrow rest mount 164 can be a separate element that is coupled to the female or male component 130 and 110 with, but not limited to, fasteners, adhesives, etc.
In an example, the quick mount system 100 includes at least one male component 110 and at least one female component 130. Additional intermediate components 150, 152, 154 and 156 may be placed between the male component 110 and and the female component 130. Coupling any two components together requires the male extrusion 112 and the female cavity 132 to be rotationally oriented, such that the ramp feature portion does not interfere. Bringing them together with the centering feature 190 and 192, coaxially aligns the components.
Rotating (clockwise or counter clockwise) one component relative to the other brings the ramp features together where they ultimately make contact with each other and thereby eliminate any further rotation. This defines the locking position and repeatably orients the multiple components 110, 150, 152, 154, 156 and 130 relative to each other. At any interface between the male protrusion 112 and the female cavity 132, the quick mount system 100 can be reconfigured to interchange an accessory (e.g., accessories 20, 30 or 40), or to add or subtract any intermediate components (e.g., components 150, 152, 154 or 156).
The locking or coupling force may be orthogonal (e.g., in one axis only) to the axis of rotation 14, or at a compound angle defined to include a minimum of any two axes of the X, Y or Z coordinate planes and bidirectional (including +X and +Z). The coupling force may apply a rotational force about the axis of rotation by fasteners 170 or 172, or both. The components 150, 152, 154, 156 include a mostly orthogonal surface 180 to the axis of the locking force to allow for the secondary force fastener 170 to intersect. Feature 180 allows the fastener 170 to either push against the mostly orthogonal surface to generate the coupling force, or have a threaded hole (not shown) for the fastener 170 or 172 to couple to and pull any two components 150, 152, 154 or 156 sharing one male protrusion 112 and one female cavity 132 together, thereby generating the coupling force.
The accessories (e.g., accessories 20, 30 or 40) may include a complementary geometric shape 166 to the mounting element 164 (e.g., a Picatinny rail oriented vertically). Accessory engagers 167 and 168 mate to the complementary features of the mounting element 164, allowing the accessory to slide relative to the mounting element 164. Fasteners 169 apply a clamping force, by bringing 167 and 168 together, compressing mounting element 164, and resulting in the mounting element 164 and the accessory (e.g., accessory 20, 30, or 40) being coupled together (e.g., so that it is not moveable). Multiple ramps 180, 182 and 184 provide a repeatable location of the accessory relative to the mounting element 164 when the clamping force is generated by the fasteners 169.
Still other embodiments are contemplated. For example, the quick mount system 100 may include a compressible spring disc which, when overcome by the interference interface between the first interfacing component and the second interfacing component, returns to a non-compressible state to apply a bias force to the interference interface to hold the first interfacing component and the second interfacing component in relative positions to one another. The compressible spring disc may include at least one integral lobe. The integral lobe of the compressible spring disc may be located at a rotational angle of a relative locking position.
In another example, the quick mount system 100 may include a secondary locking mechanism to secure the first interfacing component relative to the second interfacing component in the engagement position. The secondary locking mechanism may be a fastener that threads into and protrudes from the first interfacing component and makes an interference contact with the second interfacing component. The secondary locking mechanism may have a pivoting spring loaded lever arm interfacing with the second interfacing component, and engagement mechanism between the first interfacing component and the second interfacing component to prevent rotation relative to each other.
In yet another example, the quick mount system 100 may include an intermediate component to position the accessory at a prescribed distance from a surface of the mounting structure.
In yet another example, the first interfacing component rotates relative to the second interfacing component into a predisposed angular position where the accessory is monolithic to the mounting structure.
In yet another example, the first interfacing component rotates relative to the second interfacing component to a predisposed angular position where the first interfacing component and the second interfacing component are maintained in the engagement position at least in part by a rotational holding force.
In yet another example, the first interfacing component rotates relative to the second interfacing component to a predisposed angular position where the first interfacing component and the second interfacing component are maintained in the engagement position at least in part by at least one multiple detent that can only be overcome by an external shear force.
In yet another example, releasing the first interfacing component from the second interfacing component is only after releasing a locking ratchet mechanism prior to applying the external shear force.
In an example, the dampener system 159 includes a vibration dampening component 250 made of materials that absorb vibration generated by the structure 5 from which it is attached, or vibration generated by an external event or source that is transferred by the structure 5 from which the intermediate component 150 is attached to the male component 110 and the female component 130 of the quick connect/disconnect mounting mechanism 10. The dampener system 159 when attached to the male component 110 and the female component 130 isolates the male component 110 from the female component 130 such that the vibration disturbance is transferred through the dampener 250.
In an example, the male component 110 is coupled to the dampener 250 with a fastener 251 with a shoulder 252 and threads 254 and a washer 256. When the fastener 251 is inserted through the dampener 250 the threads 254 of the fastener 251 are mated with the threads 258 of the male component 110, the washer 256 provides increased surface area to transfer the compression force along asserted by threading the fastener 251 into the threaded hole 258 along the axis of rotation 14. The shoulder 252 of fastener 251 limits the dimension along the axis of rotation 14 thereby limiting the deformation of the dampener 250 as the shoulder makes contact with the mating surface of the male component 110.
In an example, the female component 130 is coupled to the dampener 250 with a fastener 260 that threads through the female component 130 and the dampener 250 into the coupling nut 262 that contains threads 264. When the fastener 260 threads into the threads 264 of the coupling nut 262, the shoulder of the coupling nut 266 limits the compression force asserted by threading the fastener 260 into the threaded hole 264. The shoulder 266 of the coupling nut 262 limits the dimension along the axis of rotation 14 thereby limiting the deformation of the dampener 250 as the end of the coupler nut 262 makes contact with the mating surface of the male component 130.
In an example, the male component 110 and female component 130 are not connected directly through the components of the dampener subsystem 159 except for the dampener 250. The dampener 250 is the transferring component with vibration dampening properties that is compressed between the coupling nut 262 and the washer(s) 256. The coupling nut 262 is coupled to the female component 130 and the washers 256 are coupled to the male component 110 with fasteners 251. The dimension of the shoulders 266 and 252 define the decoupling length 259 of the dampener 250 between the male component 110 and the female component 130.
In an example, the dampener 250 directly contacts the male component 110 and female component 130 through multiple surfaces 270a, b, c and d (not limited to) and 272a, 272b, and 272c that represent interfaces (not limited to) in combination with the three axes of the assembly (x, y, z). These interfaces allow for further vibration dampening through the dampener 250 to include forces imparted on the male component 110 (or vise versa) that result is the female component 130 not being coaxially aligned along the axis of rotation 14. This is represented by either the male component 110 or female component 130 having differing X and Y positions relative to the other.
In an example, the intermediate component 159, when coupled to the mail component 110 and female component 130, serves as a vibration dampening assembly as part of a series of components as part of the quick connect/disconnect mounting mechanism 10.
It is noted that the examples shown and described are provided for purposes of illustration and are not intended to be limiting. Still other examples are also contemplated.
