Description




BACKGROUND OF THE INVENTION




This invention relates to devices for rapid connection/disconnection of one member to another. The invention particularly relates to a rapid connect/disconnect system to quickly secure and remove archery accessories from a bow.




Archery accessories, such as quivers, stabilizers, and archer sights, are commonly attached to archery bows for convenience and to assist the archer in accuracy. Such accessories have traditionally included a threaded portion which threads into a mating threaded slot in the archery bow. Modern archery bows are most commonly compound bows which provide an enormous amount of force as the arrow is released. The large amount of shock or impulse force on the archery bow when the string is released by the archer is transmitted to the archery accessories attached to the bow. This force commonly causes the accessory to loosen and decreases accuracy when the accessory is an archery sight. For this reason, the threaded portions which fix archery accessories to the archery bow are generally long enough so that when tightly screwed onto the bow, this threaded fit will resist the vibration forces when the string is released. A result of the length of the threaded portion fixing the accessory to the archery bow requires that the accessory be rotated many revolutions in order to detach the accessory from the bow and then requires a similar number of rotations in the opposite direction to again secure the accessory to the bow.




It is desirable for many reasons to attach and detach archery accessories from the bow. For example, archers frequently detach accessories from the bow for transport and storage so that the bow can be maneuvered and stored more easily. Additionally, it is desirable to detach accessories from the bow during transport to reduce the possibility of damage to the accessory or the bow. In addition, cases and covers for archery bows frequently do not provide room for covering the archery bow with the accessory attached, necessitating the removal of the accessory. Furthermore, many states require that archery accessories be removed from the archery bow during transport and storage of the bow. A need for a rapid connect/disconnect to quickly and easily secure an archery accessory to an archery bow which alternately quickly and easily detaches exists in the archery industry.




In addition, a general need exists for a system which allows quick and easy attachment of one member to another so that the members are held in their connected position against unintentional release, which also provides for quick and easy disconnect of the members when desired.




SUMMARY OF THE INVENTION




The present invention is a system which allows for rapid connection and disconnection of two members, such as, for example, an archery accessory and an archery bow. According to the present invention, a rapid connect/disconnect system includes a base mount, key pin, beveled washer, nut and mounting stud. This rapid connect/disconnect system can be used to secure two members together in a wide variety of applications where rapid connection and/or disconnection of the two members is desired.




In this invention, the base mount is secured to one member, such as an archery bow, while the key pin, beveled washer, nut and mounting stud are secured to the second member, such as an archery stabilizer. The nut and the key pin are threaded onto the mounting stud such that there exist a length of the threaded mounting stud between the nut and the key pin. The beveled washer is inserted onto the mounting stud between the nut and key pin. The nut is threaded onto the mounting stud against the second member (stabilizer) to provide a base against which the system is tightly threaded. The beveled washer is flat on one side and includes a beveled surface opposite the flat side. The beveled washer is installed onto the stud such that its flat side rests against the nut and the beveled surface is extending toward the key pin. The beveled surface of the beveled washer mates a bevel machined in the base mount and assists to properly align the stud and thereby the key pin within the base mount.




A keyed socket is machined into the base mount which includes a channel, socket, and a key receiver. A neck is cut into the base mount into the socket to provide open communication through the base mount into the channel to receive the key pin. As stated, a bevel is machined into the base mount to facilitate the insertion of the key pin into the socket. The key receiver is drilled through the wall of the base mount and is of a size slightly larger than the size of the key pin so as to receive an end of the key pin.




The key pin is threaded onto the mounting stud so that its longitudinal axis is perpendicular to the longitudinal axis of the mounting stud. Upon connection of the system, the key pin on the mounting stud is inserted into the channel of the base mount past the neck and into the socket. Once the key pin is inserted into the socket, one end of the key pin is slid through the channel and into the key receiver. The mounting stud which is fixed into the second member (archery stabilizer) is rotated so that the key pin is threaded toward the nut along the length of the mounting stud. The beveled surface of the beveled washer then properly aligns the key pin into the keyed socket and seats into the bevel machined into the base mount. The mounting stud is rotated until the beveled surface of the beveled washer is tightened against the bevel of the base mount and the flat surface of the beveled washer is tightened against the nut. The end of the key pin extending into the key receiver of the base mount insures that the base mount remains tightly secured against the beveled washer so that the first member (archery bow) and the second member (archery stabilizer) remain securely connected together.




In order to disconnect the system, the mounting stud is rotated in the opposite direction such that the key is threaded away from the nut along the length of the mounting stud. The key is then removed from the keyed socket of the base mount. The second member (archery stabilizer) is thereby disconnected from the first member (archery bow).




It is an object of the present invention to provide a connect/disconnect system to allow rapid connection and/or disconnection of one member to another.




It is a further object of the present invention to provide a system for connection (or disconnection) of an archery accessory to an archery bow capable of withstanding the impuse/vibrational forces resulting from use of the bow.




A still further object of the present invention is to provide a system which allows the archer accessory to be rapidly and easily connected or disconnected to the archery bow.

Base mount


12


includes a keyed socket


34


therein into which key pin


14


is inserted. The shape of keyed socket


28


mates the shape of key pin


14


.




Referring now to

FIG. 7

, a side view of base mount


12


, it can be seen that an interior channel


28


is machined into base mount


12


. Channel


28


is machined through the bottom surface


24


of base mount


12


and extends into base mount


12


a sufficient depth to allow keyed socket


34


to be machined into base mount


12


. An annular passage


30


, shown in phantom, is drilled through the top


32


of base mount


12


into channel


28


. The purpose of passage


30


is to receive a fastener, such as a screw used to secure base mount


12


to an object as desired. In this preferred embodiment, a socket head cap screw (not shown) is inserted into channel


28


through passage


30


and threaded into an archery bow which is drilled and tapped to receive the socket head cap screw. The thread pitch of the socket head cap screw mates the threads of the archery bow. This thread pitch is preferably a standard pitch known in the industry such as defined by the Archery Manufacturer's & Merchant's Association (AMO). In this manner, base mount


12


is secured to an archery bow.




Keyed socket


34


is machined into base mount


12


. Referring to

FIG. 8

, keyed socket


34


includes a slot, or socket


36


, and a key receiver


38


(shown in phantom). A neck


40


,

FIGS. 1

,


8


, and


9


, is cut into base mount


12


from bottom surface


24


into socket


36


. Neck


40


opens into channel


28


to provide open communication from bottom surface


24


into channel


28


in order to receive key pin


14


. The diameter of socket


36


is slightly larger than the diameter of key pin


14


so that key pin


14


can be inserted into and past bottom surface


24


through neck


40


and into socket


36


. A bevel


42


is machined into base mount


12


to facilitate the insertion of key pin


14


into socket


36


.




Referring to

FIG. 10

, key receiver


38


is drilled through the wall of base mount


12


approximately 180° around the circumference of base mount


12


. It is understood, however, that key receiver


38


may be drilled at other locations around the circumference of base mount


12


without departing from the spirit and scope of the present invention. Key receiver


38


differs from socket


36


in that key receiver


38


lacks neck


40


. Instead, a segment


80


of base mount


12


separates key receiver


38


from bottom surface


24


of base mount


12


.




The diameter of key receiver


38


is slightly larger than the diameter of key pin


14


so as to receive an end of key pin


14


. In this manner, as will be discussed in greater detail below, one end of key pin


14


may be inserted through socket


36


into key receiver


38


so that the other end of key pin


14


rests in socket


36


.





FIG. 11

is a view taken along line

of

FIG. 9

in order to show the communication between channel


28


, passage


30


, socket


36


, and key receiver


38


within base mount


12


.




Referring back to

FIG. 1

, beveled washer


16


includes a center passage


60


through which mounting stud


20


is inserted. Beveled washer


16


is flat on one side


62


and includes a beveled surface


64


opposite flat side


62


. Upon installation, beveled washer


16


is positioned on mounting stud


20


such that its flat side


62


is adjacent nut


18


while its beveled surface is directed toward key pin


14


.




In the preferred embodiment, beveled washer


16


is a belleville washer available commercially; however, it is understood that other washers having a similar configuration, or even a washer having flat surfaces on both sides, could be substituted. As will be discussed in greater detail below, beveled surface


64


of beveled washer


16


mates a bevel


26


machined in channel


28


of base mount


12


adjacent bottom surface


24


and assists to properly align mounting stud


20


and thereby key pin


14


within keyed socket


34


of base mount


12


when beveled washer


16


is tightened against bevel


26


and bottom surface


24


when in the connected position (as shown in FIGS.


2


and


3


).




As described above, nut


18


threads into mounting stud


20


between stabilizer


22


and beveled washer


16


. Nut


18


includes a threaded bore


70


therein having threads which mate the threads of mounting stud


20


. In the preferred embodiment, nut


18


is a hex nut; however, it is understood that other similar fasteners could be substituted provided the threads mate the threads of mounting stud


20


. Nut


18


provides a locking surface on mounting stud


20


against which key pin


14


can be tightened so as to secure base mount


12


between beveled washer


16


and key pin


14


when in the connected position.




Mounting stud


20


is substantially a threaded rod of a predetermined length. The length of mounting stud


20


is dependent upon the desired application. In the preferred embodiment, mounting stud


20


of stabilizer


22


is an industry AMO standard for archery accessories. For this application AMO defines the standard for the thread series and length of mounting stud


20


. However, it is understood that the length and thread series of mounting stud


20


could be modified as required by the desired application.




The rapid connect/disconnect system


10


of the present insertion is assembled by threading nut


18


onto mounting stud


20


. Beveled washer


16


is then placed upon mounting stud


20


so that flat side


62


is adjacent nut


18


. Mounting stud


20


is then inserted into stud aperture


50


of key pin


14


, and key pin


14


is threaded onto mounting stud


20


such that a space or length of stud


20


is left between beveled washer


16


and key pin


14


. Rapid connect/disconnect system


10


is now assembled to provide rapid connection/disconnection capability to allow stabilizer


22


to be quickly connected or disconnected from base mount


12


.




As stated above, a first member, such as base mount


12


, is secured to an object (such as a bow in the preferred embodiment) by inserting a socket head cap screw through passage


30


and into a bow. Once base mount


12


is secured, rapid connect/disconnect system


10


can be used to facilitate the connection of a second member, stabilizer


22


in the preferred embodiment, by interlocking key pin


14


into keyed socket


34


of base mount


12


.




Key pin


14


is threaded onto mounting stud


20


as described above, such that its longitudinal axis is perpendicular to the longitudinal axis of the mounting stud


20


. Key pin


14


is then inserted into keyed socket


34


and locked therein to secure stabilizer


22


to base mount


12


. This is accomplished by inserting key pin


14


on mounting stud


20


into channel


28


(shown in phantom) past neck


40


and in socket


36


. Once key pin


14


is inserted into socket


36


, key pin


14


on mounting stud


20


is slid into key receiver


38


.




Once key pin


14


on mounting stud


20


is properly inserted into keyed socket


34


, mounting stud


20


, and thereby stabilizer


22


of the preferred embodiment, is rotated so that key pin


14


is threaded toward nut


18


. Beveled surface


64


of beveled washer


16


properly aligns key pin


14


into keyed socket


34


and seats into bevel


26


of base mount


12


. Mounting stud


20


is rotated until beveled surface


64


of beveled washer


16


is tightened into bevel


26


against bottom surface


24


of base mount


12


, and flat surface


62


is tightened against nut


18


. The length of key pin


14


extending into key receiver


38


ensures that base mount


12


remains tightly pressed against beveled washer


16


so that stabilizer


22


remains secured to base mount


12


, and thereby the bow. The amount of rotation of mounting stud


20


to secure stabilizer


22


to base mount


12


is approximately one and one-half (1½) revolutions.




In order to disconnect key pin


14


from base mount


12


, mounting stud


20


is rotated approximately one and one half (1½) revolutions in the opposite direction so that key pin


14


is threaded away from nut


18


. This separates beveled washer


16


from bottom surface


24


of base mount


12


so that key pin


14


can be slid out of key receiver


38


, away from socket


36


, past neck


40


, and out of channel


28


, thereby disconnecting stabilizer


22


from key pin


14


and the bow. A rapid connect/disconnect system is thereby provided.




Now referring to

FIG. 2

, which is a side view of the rapid connect/disconnect system


10


of the present invention in the connected position.

FIG. 2

shows the relationship of base mount


12


, key pin


14


, mounting stud


20


, beveled washer


16


, and nut


18


in the connected, or locked position.




Referring to

FIG. 3

, a partial cut-away view taken along line


3


—

of

FIG. 2

, the relationship between base mount


12


, key pin


14


, mounting stud


20


, beveled washer


16


, and nut


18


, is shown. Flat surface


62


of beveled washer


16


is shown abutting nut


18


so that its beveled surface


64


is pressed into bevel


26


of base mount


12


adjacent bottom surface


24


, thereby properly aligning key pin


14


into socket


36


. Key pin


14


is shown tightened against segment


80


of base mount


12


such that a gap


82


can be seen between key pin


14


and socket


36


. In this manner key pin


14


ensures that stabilizer


22


is secured to base mount


12


.





FIG. 3

also shows the relationship between mounting stud


20


and base mount


12


. Since key pin


14


is threaded onto mounting stud


20


, a segment of mounting stud


20


extends into channel


28


of base mount


12


when key pin


14


is secured in socket


36


in the connected position.




It is understood that base mount


12


could be configured in a plurality of shapes as required for a particular application. It is further understood that the shape of key pin


14


, and thereby socket


36


and key receiver


38


, could be altered provided that key pin


14


interlocks with socket


36


and key receiver


38


in keyed socket


34


.




While the invention has been described with a certain degree of particularity, it is manifest that many changes may be made in the details of construction without departing from the spirit and scope of this disclosure. It is understood that the invention is not limited to the embodiment set forth herein for purposes of exemplification, but is to be limited only by the scope of the attached claim or claims, including the full range of equivalency to which each element thereof is entitled.
