DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] FIG. 1 illustrates an implement attachment device 7 configured to be mountable on a tractor bucket 3 where the tractor bucket is attached to one or more tractor arms 2 of a tractor 1. The implement attachment device 7 includes a main receiver bar 10 that is provided with one or more receivers 12 that serve as sockets into which the shank 41 of an implement 40 may be fitted. An implement pin 16 is used to reversibly attach the implement 40 to the main receiver bar 10 by reversibly pinning the shank 41 of the implement 40 within the body of the receiver 12. The main receiver bar 1.0 is rigidly affixed to a pair of swing arms 14. In one embodiment, rigid affixation of the swing arms 14 to the main receiver bar 10 is accomplished by means of at least one fastener 18 per swing arm 14 rigidly affixing the swing arms 14 to the main receiver bar 10. Each swing arm 14 is attached to a side wall 4 of the tractor bucket 3 by a pivot pin 20 and a positioning pin 22. The implement attachment device 7 is shown in a use-ready position in FIG. 1. in which the swing aims 14 are angled downward from the location of the pivot pin 20 toward the bottom wall 5 of the tractor bucket 3 such that the main receiver bar 10 is located toward the bottom of the bucket 3 and in close proximity to the front edge of the bottom wall 5 of the tractor bucket 3 with the one or more receivers 12 facing forward. As can be seen in referring to FIG. 1, when the implement attachment device 7 is in a use-ready position, the top position hole 27 through each sidewall 4 of the bucket 3 is not in use because the positioning pin 22 is engaged in the bottom position hole (not shown) in order to maintain the implement attachment device 7 in the use-ready position. In a preferred embodiment, the implement attachment device 7 will also feature a pair of support members 24, each of which is a protrusion that is rigidly affixed to, and extending from, a surface of each sidewall 4 of the tractor bucket 3. The support members 24 physically support the swing arms 14 when the implement attachment device 7 is in the use-ready position as shown in FIG. 1. The support members 24 are either a metal protrusion welded onto each sidewall 4 of the bucket 3, or preferably, a bolt or screw that is rigidly affixed to the sidewall 4, possibly using a nut or washer and nut where the bolt or screw is inserted through a support hole (not shown in FIG. 1) in the sidewall 4 and engages the nut on the opposing planar side of the sidewall 4. It is also possible to use a pin as a rigid support member 24 without departing from the scope of the inventive concepts hereby disclosed. While the inventive concepts disclosed may be practiced without the rigid support members 24, it is not advisable to do so since the support members 24 provide physical support for carrying heavier loads using the attached implements 40.

[0028] FIG. 2 is an exploded front perspective view of the implement attachment device 7 and the tractor bucket 3 that illustrates additional features of the implement attachment device 7. As can be seen in FIG. 2, the main receiver bar 10 includes at least one, and preferably a multiplicity of, receivers 12, wherein each receiver 12 has one or more receiver holes 17 that pass through one or more walls of the receiver 12. As shown by path lines in FIG. 2, an implement 40 may be inserted into a receiver 12 by inserting the shank 41 of the implement 40 into a receiver 12 and then inserting an implement pin 16 through the receiver holes 17 and through a pin hole 42 that is provided through the shank 41 of the implement 40. The implement pin 16 may be any suitable type of attachment means such as a screw, bolt, hitch pin, or other similar attachment means, but in a preferred embodiment the implement pin 16 is a bolt or a pin secured in place by a cotter pin 11 (such as a clevis pin—cotter pin combination or other similar arrangement) that fits around an end of the implement pin 16 or through a hole provided through the implement pin 16 (not shown) to secure it in place in a manner that is well understood by those skilled in the art.

[0029] As can be appreciated from viewing the path lines shown in FIG. 2, during assembly of the implement attachment device 7 onto the tractor bucket 3, the pair of swing arms 14 will connect the main receiver bar 10 to the tractor bucket 3. Each swing arm 14 has a top pivot end 15 and a bottom slide end 17 that are orthogonal to each other. The top pivot end 15 of each swing arm 14 is reversibly attached to a sidewall 4 of the tractor bucket 3 by means of a pivot pin 20 and a positioning pin 22. As illustrated by path lines in FIG. 2, when the implement attachment device 7 is assembled on the tractor bucket 3, the pivot pin 20 is inserted through an arm pivot hole 30 that is disposed within the top pivot end 15 of each swing arm 14, and also through a bucket pivot hole 21 that is disposed within each side wall 4 of the tractor bucket 3. As further illustrated by path lines shown in FIG. 2, the top pivot end 15 of each swing aim 14 is reversibly connected to the tractor bucket 3 with a positioning pin 22 that is reversibly inserted through an arm positioning hole 29 and into either a bottom position hole 23 or a top position hole 27, both of which position holes are disposed at different locations within each sidewall 4 of the tractor bucket 3.

[0030] After assembly, the implement attachment device 7 will be in a use-ready position when the positioning pin 22 is inserted through the arm positioning hole 29 and through the bottom position hole 23. This arrangement will place the main receiver bar 10 into close proximity with the leading edge of the bottom wall 5 of the tractor bucket 3 with the one or more receivers 12 facing forward in relation to the bucket 3, and in this use-ready position, any attached implement 40 held by the main receiver bar 10 will extend forward from the leading edge of the bottom wall 5 of the tractor bucket 3. The implement attachment device 7 can be moved to a stowed position by removing the positioning pin 22 from the bottom position hole 23, swinging the top pivot ends 15 of both swing arms 14 upwards such that the main body of the device, including both swing arms 14 and the main receiver bar 10 that is connected between then, is rotated upwards around the pivot pin 20, and then inserting the positioning pin 22 into the top position hole 27. These steps will move the implement attachment device 7 from a use-ready position to a stowed position in which the swing arms 14 and main receiver bar 10 are held in place near the top of the bucket 3 by the positioning pins 20. Once the implement attachment device 7, including each swing arm 14 and the main receiver bar 10, is in the stowed position near the top of the tractor bucket 3, the tractor bucket 3 can then be used to scoop up, handle, and move particulate material in standard manner without interference from the implement attachment device 7 or any implement 40 that may still be attached to the main receiver bar 10 of the device. The pivot pins 20 will stay in their position in which they are engaged through the arm pivot holes 30 of the swing arms 14 and through the bucket pivot holes 21 of each sidewall 4 during the entire time that the device is switched between a use-ready position and a stowed position.

[0031] As illustrated in FIG. 2 and FIG. 3, during assembly of the implement attachment device 7 onto the tractor bucket 3, the bottom slide ends 17 of the swing arms 14 are initially slidably connected to opposite ends of the main receiver bar 10 by inserting the bottom slide ends 17 in male-female fashion into openings that are disposed within each end of the main receiver bar 10 for receiving and slidably holding the bottom slide end 17 of a swing arm 14. Each bottom slide end 17 has a smaller cross-sectional area or smaller diameter than the openings at the ends of the main receiver bar 10 that serve as receiving means for the bottom slide ends 17, and therefore, during assembly but prior to final assembly, each bottom slide end 17 of each swing arm 14 is capable of sliding freely into and sliding to and fro within the body of the main receiver bar 10. During the assembly process, each bottom slide end 17 is adjusted by sliding it within the body of the main receiver bar 10 to a point where each swing arm 14 is in position adjacent to a sidewall 4 of the bucket 3 such that the top pivot end 15 of each swing arras 14 can be pinned to a sidewall 4 of the tractor bucket 3. The top pivot ends 15 of the swing arms 14 are then pinned to the bucket 3 using the pivot pins 20 that are inserted through the aim pivot holes 30 disposed within the pivot ends 15 and the bucket pivot holes 21 that are disposed within the sidewalls 4, and optionally also using the positioning pins 22 to pin the pivot ends 15 of the swing arms 14 to the sidewalls 4. Final assembly will involve the bottom slide ends 17 of each swing arm 14 being rigidly affixed to the main receiver bar 10. In some embodiments, rigid affixation of the bottom slide end 17 of each swing arm 14 to the main receiver bar 10 may be accomplished using one or more pre-marked holes 32 in the bottom slide ends 17 and one or more pre-set holes 19 in the main receiver bar 10, along with a bolt 18. Rigid affixation of each bottom slide end 17 of each swing aim 14 to the main receiver bar 10 may alternatively be accomplished using any other rigid affixation means, including but not limited to use of a screw with a nut or nut and washer, welding, pinning, or any other similar means that are well understood in the art. To the extent that pre-marked holes 32 may optionally be located on the bottom slide end 17 of each swing arm 14 in some embodiments, along with pre-set holes 19 that may optionally be located on the main receiver bar 10 at predetermined distances apart, the locations and distances of such pre-marked holes 32 and pre-set holes 19 will be such that the overall structure of the implement attachment device 7 may be adjusted to fit tractor buckets of several different commonly-encountered widths at the time of assembly. Use of pre-marked holes 32 and pre-set holes 19 is not required to practice the invention, but are part of an optional embodiment. In a preferred embodiment, the implement attachment device 7 will be able to be assembled onto any tractor bucket 3 having a width of between 48 inches to 72 inches, with the width of the bucket 3 being the distance measured between the outside planar surfaces of the opposing sidewalls 4 of the bucket 3. Thus, in such a preferred embodiment, the bottom slide ends 17 of the swing arms 14 are capable of being slidably adjusted during assembly by sliding them to and fro within the body of the main receiver bar 10 and then rigidly affixing each to the main receiver bar 10 during final assembly in a position such that the top pivot ends 15 of the pair of swing arms 14 will be anywhere from 48 inches to 72 inches apart when the implement attachment device 7 is finally assembled on a bucket, with the distance between the top pivot ends 15 of the swing arms 14 being determined by the width of the tractor bucket 3 onto which the device is being assembled.

[0032] FIG. 4 is a front view of the implement attachment device 7 mounted on a tractor bucket 3, which is, in turn, mounted on tractor arms 2 of a tractor 1. Arrows in FIG. 4 demonstrate the removal of the positioning pins 22 from the bottom position holes (not shown in front view) that are disposed through the sidewalls 4 of the tractor bucket 3. Removal of the positioning pins 22 is required in order to switch the implement attachment device 7 from the use-ready position at the bottom of the tractor bucket 3 where the main receiver bar is located near the bottom wall 5 of the bucket 3 to a stowed position near the top of the tractor bucket 3 by rotating the main body of the device, including the swing arms 14 and the main receiver bar 10, upwards around the pivot pins 20 that will stay in place during this switch.

[0033] FIG. 5 is a front perspective view of the implement attachment device 7 mounted on a tractor bucket 3 where the switching of the implement attachment device 7 from the use-ready position 101 that is shown in phantom with a dashed line, to an upright stowed position 102, is illustrated. The curved arrow 103 illustrates rotation of the implement attachment device 7 and an attached implement 40 upward around the pivot pin 20 to the stowed position 102. Additional arrows demonstrate insertion of the positioning pins 22 into the top position holes (not labeled) in order to place the device into the stowed position 102 near the top of the bucket 3.

[0034] FIG. 6 is a side view of the implement attachment device 7 mounted on a tractor bucket 3 in the stowed position 102. As can be observed in reference to FIG. 6, when the device is in a stowed position 102, both swing arms 14, the main receiver bar (not visible in side view), and any implement 40 that may be attached to a receiver 12 by means of an implement pin 16, will be located near the top of the bucket 3 and away from the bottom wall 5 of the bucket 3. FIG. 6 illustrates that the positioning pins 22 are not engaged in the bottom position holes 23 that are disposed through each sidewall 4, but rather, they are engaged with the top position holes (not shown) closer to the top of the bucket 3 such that the implement attachment device 7 is no longer in front of the tractor bucket 3, but is in the stowed position 102 at the top of the bucket 3.

[0035] FIG. 7 is a side view of the implement attachment device 7 illustrating use of the tractor bucket 3 to scoop materials up when the implement attachment device 7 is pinned in a stowed position 102 near the top of the bucket 3. The tractor bucket 3 is illustrated as moving with scooping action from a first bucket location 202′ that is shown in phantom with dashed lines, to a second bucket location 202, while the implement attachment device 7 remains in the stowed position 102 (the device in the stowed position prior to movement of the bucket is shown in phantom at location 102′ with dashed lines). As can be visualized and understood from reviewing FIG. 7, when the implement attachment device 7 is pinned in a stowed position 102, the implement attachment device 7 will be located away from the bottom wall 5 of the bucket 3 and therefore the bucket 3 can be used in standard fashion to scoop up particulate materials and move them from one place to another.

[0036] FIG. 8 is a front perspective view of the implement attachment device 7 assembled on a tractor bucket 3 where the tractor bucket 3 is illustrated as being raised upward by a curved arrow 303 in order to move or haul particulate materials in the bucket 3 in standard fashion. As can be seen, when the tractor bucket 3 is raised from an initial lower position 301 illustrated in phantom by dashed lines, to a subsequent higher position 302, the implement attachment device 7, including the main receiver bar 10 and the swing anus 14, along with any attached implement 40, moves with the bucket 3 as it is raised to the higher position 302. Thus, the implement attachment device 7 can remain in the stowed position without interfering with an operator raising or lowering the tractor bucket 3, and without interfering with moving or hauling of particulate materials from one place to another using the tractor 1 and its bucket 3.

[0037] FIG. 9 is a front perspective view of the implement attachment device 7 as assembled on a tractor bucket 3 with the implement attachment device 7 in a use-ready position in which the positioning pins 22 have been removed from the top position holes 27 that are disposed within the sidewalls 4 of the tractor bucket 3 and have been re-pinned in the bottom position holes (not labeled) that are located closer to the bottom wall 5 of the tractor bucket 3. The embodiment of the implement attachment device 7 is shown with the optional support members 24 in place on the sidewalls 4 to provide physical support for the swing arms 14 of the device. FIG. 9 illustrates the fact that a platform type implement 50 may be attached to the bucket 3 using the implement attachment device 7 by inserting the shanks (not shown) of the platform type implement 50 into the receivers 12 of the main receiver bar and reversibly pinning them in place by inserting implement pins (not labeled) through one or more receiver holes (not labeled) disposed within the receivers 12 and through pin holes disposed (not visualized) within the shanks of the platform type implement 50 in a similar fashion to what was previously illustrated for the implement 40 that is shown in FIG. 2.

[0038] FIG. 10 demonstrates that a ball hitch type implement 60 may be inserted into a receiver 12 of the main receiver bar 10 and pinned in place using an implement pin 16. The ball hitch type implement 60 allows the operator of a tractor to move ball hitch trailers (not shown) from one place to another using a tractor on which the device has been assembled.

[0039] FIG. 11 and FIG. 12 both illustrate that a roller implement 72 may be attached using the device by the interconnection method 70 demonstrated in which implement pins 16 are used to connect the roller implement 72. FIG. 12 also specifically illustrates an alternative embodiment of the implement attachment device 74 in which the entire implement attachment device is all one unitary piece of metal or plastic and there is no assembly of individual swing arms and main receiver bar to form an assembly because the entire implement attachment bar is a single, unitary piece of equipment that comprises a metal or plastic frame with main receiver bar and swing arms that are all part of the unitary structure that can be attached to the sidewalls of a tractor bucket and used to attach various types of implements such as the roller implement 72 that is illustrated.

[0040] The primary purpose of FIG. 10-FIG. 12 is to demonstrate that a multiplicity of different types of tools and implements may be attached to a tractor bucket using the implement attachment device and that the types of tools or implements that may be attached using the device are not limited to fork or tine type tools. In practice, several other implements that are not illustrated by the drawings, such as a grape vine puller and an elongated hay spike, have also been demonstrated as implements that may be attached to a tractor bucket using the implement attachment device, wherein each implement has one or more shanks with pin holes such that the shanks of the implements may be inserted into one or more receivers of the main receiver bar and pinned in place with implement pins in a manner similar to what has been shown and illustrated in the attached patent drawings.

[0041] For purposes of the drawings and the description provided hereinabove, the connections between the swing arms 14 and the sidewalls 4 of the bucket 3 may be pins, bolts, screws, or any other similar fastener that may be used to reversibly connect the swing arms 14 to the sidewalls 4 utilizing the various types of holes in the swing arms 14 and sidewalls as have been described. The terms “pin,” “bolt,” or screw,” are not meant to be limiting, and it should be understood that any type of reversible fastener that allows for rotational pivoting motion of the top pivot end 15 of the swing arms 14 in order to move the implement attachment device 7 between the use-ready position 101 and the stowed position 102 comes within the scope of the inventive concepts defined within the appended hereto. Likewise, any type of reversible fastener that allows for reversibly locking the implement attachment device 7 in place in either the stowed position 102 or the use-ready position 101 comes within the scope of the inventive concepts.

[0042] In a preferred embodiment of the inventive concepts disclosed, all of the connections between the pivot ends 15 of the swing arms 14 and the sidewalls 4 of the bucket 3 are pins that may be relatively quickly pinned or unpinned in place as described in the foregoing descriptions. The reason for the use of pins in the preferred embodiment instead of bolts or screws with a nut or locking nut, is that pins can be readily removed in order to disconnect the entire implement attachment device from the bucket of a tractor and then simply move the tractor and its bucket backward away from the device. While other previous implement adapter devices have been touted as providing a “quick-release” feature or other similar ease of connection and disconnection, the implement attachment device that is hereby disclosed actually fulfills such promises because removal of two pins on each side of the tractor bucket is all that is required to disconnect the device from the tractor.

[0043] To the extent that pins are used in some embodiments of the device, including the preferred embodiment, the pins that are employed may be a clevis pin—cotter pin type combination, bow-tie locking cotter pin combination, hitch pin, or any other similar type of pin or pin combination that provides for easy connection and easy disconnection of the swing anus and the sidewalls of the bucket. The connections may also be accomplished using bolts, screws, washers, or other similar reversible connection means, but quickly removable pins are the preferred types of connectors for the device for the reasons stated above.

[0044] It should also be recognized that the support members 24 shown in the drawings and discussed in the description above, though optional, are an important aspect of the preferred embodiment of the inventive concepts hereby disclosed. While such support members 24 connected to the sidewalls are not strictly required to practice the inventive concepts disclosed, to the extent that extremely heavy loads are to be loaded onto one or more implements attached to the tractor bucket 2 using the implement attachment device 7, the support members 24 will provide a significant amount of physical support to the swing arms 14 supporting the heavy load. The support members 24 may be welded metal protrusions, bolts, screws, washers, or any other type of solid protrusion from the sidewalls 4 that serves as a support for the swing arms 14. Alternatively, the inventive concepts disclosed may be practiced with alternative types of support for the device, such as support means rigidly affixed to the bottom wall 5 of the bucket 3 that would underlie and support the main receiver bar 10 when it is in a use-ready position. Although such alternative means of support come within the scope of the inventive disclosure described and hereinafter claimed, the inventor's preferred embodiment involves support members that are rigid protrusions from the sidewalls of the bucket.

[0045] With regard to the pre-marked holes 32 provided along the bottom slide end 17 of each swing arm 14 and the pre-set holes 19 provided in the main receiver bar 10 in some embodiments, it should be appreciated that such pre-marked holes 32 and such pre-set holes 19 are not strictly necessary to practice the inventive concepts disclosed. Furthermore, to the extent that such pre-marked holes 32 and such pre-set holes 19 are used in a preferred embodiment of the implement attachment device 7, there will be two pre-set holes 19, with each of pre-set holes 19 being a true hole through the main receiver bar 10 that is located in relative proximity to the ends of the main receiver bar 10 and at some distance from the center of the main receiver bar 10. With reference to the pre-marked holes 32, such pre-marked holes 32 will not be true holes through the bottom slide ends 17 of the swing arms 14, but rather, the pre-marked holes 32 will be a multiplicity of dimples or etched spots within each of the bottom slide ends 17 where a true hole through each of the bottom slide ends 17 can be drilled during assembly of the device in order to subsequently rigidly affix the bottom slide ends 17 of the swing arms 14 to the main receiver bar 10 by means of bolts, screws, or pins in the manner described above. The reason for using dimples or etched spots for the pre-marked holes 32 along the bottom slide ends 17 rather than actual pre-drilled holes is that the inventor has discovered during a reduction to practice that a multiplicity of pre-drilled holes that are actual holes through bottom slide ends 17 of the swing arms 14 reduces the overall integrity and physical strength of the entire implement attachment device 7 once it is assembled and put into use. As a result, in a preferred embodiment incorporating,the pre-marked holes 32 that are set at certain distances along the bottom slide ends 17, the assembler of the device will position the bottom slide ends 17 of the swing arms 14 within the ends of the main receiver bar 10 and slide the swing arms 14 to the proper width apart in relation to the width of the tractor bucket 3, and then the assembler will drill an actual hole through one of the pre-marked holes 32 in each of the bottom slide ends 17 and use a bolt, screw, or pin to rigidly affix each of the swing arms 14 to the main receiver bar 10 using each of the now-drilled pre-marked holes 32 in a manner that is well understood in the art.
