DETAILED DESCRIPTION
While this invention is susceptible of embodiments in many different forms, exemplary embodiments of the invention are shown in the drawings and will herein be described in detail with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiments illustrated.
Referring now to FIG. 1, there is shown an embodiment of a cooling tool or hunter field tool, generally designated by the reference numeral 10. The tool 10 can be used by hunters in the field to cool and harvest a carcass, such as a deer, prior to transporting the carcass for further processing. The tool 10 generally includes a first member 12 and a second member 14. As described in greater detail below, the members 12, 14 are cooperatively associated with one another such that the second member 14 is lockable in a plurality of positions with respect to the first member 12. The structure of the tool 10 will first be described below, followed by a description of the operation of the tool 10.
As shown in FIG. 1, the first member 12 has a first cylindrical body or part 13 and an integral first gripper 15 connected at an end of the body 13. In the embodiment shown, the first gripper 15 is integrally formed with and integrally connected to the first cylindrical body 13. However, in another embodiment, the first gripper 15 may be formed as a separate piece from the body 13, and may be connected to the body 13 in another manner. Additionally, in this embodiment, the first member 12 is formed of two pieces 16A, 16B. FIGS. 3-5 illustrate the first piece 16A of the first member 12, which has a plurality of projections in the form of pins 17 alternating with holes 19 spaced along the interior edges 18. The second piece 16B, also shown in FIGS. 3-4, has corresponding pins 17 and pin-sized holes 19 along the interior edges 18, with the holes 19 being dimensioned to fit the pins 17 to fit in an abutting press-fit or snap-fit position with the first piece 16A to form the first member 12. The first and second pieces 16A-B in this embodiment also have ridges 59 on the interior edges 18. These ridges 59 provide material for sonic welding, so the pieces 16A-B can be sonically welded together after connection, to further secure the pieces 16A-B together. It is understood that additional joining techniques can be used to further secure this connection, such as other types of welding, adhesives, complementary linking or snapping structures, or fasteners, such as bolts, nuts, and lock washers, etc. It is also understood that alternate connection techniques an be used in place of the complementary pins 17 and holes 19, including the aforementioned techniques. In this embodiment, as shown in FIG. 4, the first and second pieces 16A-B are substantially identical to each other, each having a partial or semi-cylindrical portion 60 and a partial grip portion 61 integrally formed with the semi-cylindrical portion 60. FIG. 5 illustrates only the first piece 16A. When the two pieces 16A-B are connected together, the semi-cylindrical portions 60 combine to form the cylindrical body 13 and the partial grip portions 61 combine to form the first gripper 15. In another embodiment, the first member 12 may be formed of a single piece, or a larger number of pieces.
As shown in FIGS. 2-5, the first cylindrical body 13 is hollow, with an internal chamber 62 formed therein and defined by the internal wall 11. In this embodiment, the internal chamber 62 has two openings 63, 64 at opposite ends of the first member 12 with two sets of internal grooves along the interior wall 11. As shown in FIGS. 3-5, the first set of internal grooves is a pair of longitudinal grooves 21, one opposite the other (e.g., spaced 180 degrees on the member 12) in parallel, which extend along the length of the internal wall 11 of the first cylindrical body 13. The second set of internal grooves are a plurality of locking grooves 23 (i.e. two or more) in communication with the longitudinal grooves 21. In this embodiment, the locking grooves 23 are L-shaped grooves 23 spaced evenly along each of the longitudinal grooves 21, with each longitudinal groove 21 having four locking grooves 23 connected thereto. The locking grooves 23 are arranged in pairs located on substantially opposite sides of the chamber 62. The locking grooves 23 closest to the first gripper 15 are in a first groove position L1, and the locking grooves 23 closest to the opposite end of the first cylindrical body 13 are in a fourth groove position L4, with the locking grooves 23 in between serving consecutively as second and third groove positions L2, L3. The locking grooves 23 have a horizontal portion or segment 45, which is in communication with the corresponding longitudinal groove 21 and extends transversely to the longitudinal groove 21, and a vertical portion or segment 46, which extends from the horizontal portion 45 towards the first gripper 15 and is generally parallel to the longitudinal groove 21. In the embodiment shown, the horizontal segment 45 extends perpendicular to the longitudinal groove 21 and the vertical segment 46 extends perpendicular to the horizontal segment 45. It is understood that a single longitudinal groove 21 and corresponding single set of locking grooves 23 could be used in another embodiment.
The first gripper 15 is shown in FIGS. 1-5 and is integral with the first cylindrical body 13, as described above. As shown in FIGS. 2-5, the first gripper 15 is U-shaped having a bottom side 20 and generally curved upper sides 26. In this embodiment, the first gripper has two types of sharp protrusions along the interior surface of the sides 20, 26. The first type of sharp protrusions 25 is larger and project from the curved internal upper sides 26 of the first gripper 15. The second type of sharp protrusions 22 are smaller than the first type 25 and project from the curved interior bottom side 20 of the first gripper 15. The first gripper 15 also has an opening 64 of the chamber 62 therein, as also described above.
As shown in FIGS. 1-4 and 6, the second member 14 has a second cylindrical body 24 at one end and a second gripper 28 connected to the body 24 at the other end. In this embodiment, the second member 14 is comprised of three pieces, with the cylindrical body being formed of two partial or semi-cylindrical pieces 29,30, shown in FIGS. 3, 4, and 6, and the second gripper 28 being formed of a separate, single piece 27, as shown in FIGS. 3, 4, 7, and 8. Additionally, the first and second pieces 29, 30 have complementary protrusions and holes for connection, similarly to the first and second pieces 16A-B of the first cylindrical body 13. FIG. 6 shows the first piece 29 of the second cylindrical body 24, which has protrusions in the form of pins 31 protruding along the internal edges 33. The second piece 30 of the second cylindrical body 24, shown in FIG. 4 along with the first piece 29, has corresponding pin-sized holes 32 along the internal edges 33. The first piece 29 and the second piece 30 fit in an abutting press-fit or snap-fit position to form the second cylindrical body 24 of the second member 14. The first and second pieces 29, 30 in this embodiment also have ridges 57 on the interior edges 33. These ridges 57 provide material for sonic welding, so the pieces 29, 30 can be sonically welded together after connection, as described above. As similarly described above, additional or alternate joining techniques can be used to secure the connection between the pieces 29, 30. In another embodiment, the second member 14 may be formed of a smaller or a larger number of pieces. Further, while the second cylindrical body 24 is hollow in this embodiment, in other embodiments, it may be partially or completely solid.
As shown in FIGS. 2-4 and 6, the second cylindrical body 24 is hollow with a first end 34 for attaching the second gripper 28 and a second end 35 for connecting with the first member 12. The second end 35 has two projections 36 on the external surface of the second member 14 that run along the bottom edge 37 of the second cylindrical body 24. The projections 36 are on opposite sides (generally spaced 180 degrees apart) of the second cylindrical body 24. It is understood that a single projection could be used, such as in an embodiment with a single longitudinal groove 21 and a single set of locking grooves 23 connected thereto, and the projections 36 could take various shapes.
As shown in FIGS. 2, 4, 7, and 8, the second gripper 28 is an attachable piece for attachment to the second cylindrical body 24. The second gripper 28 has a top U-shaped portion 39 and a bottom cylindrical neck portion 40. The U-shaped portion 39 has curved internal upper sides 52 and a bottom side 54. The U-shaped portion 39 of the second gripper 28 has two types of sharp protrusions along the interior surface. The first type of sharp protrusions 56 is larger and projects from the curved internal upper sides 52 of the U-shaped second gripper 39. The second type of sharp protrusions 58 is smaller than the first type and projects from the curved interior bottom sides 54 of the U-shaped portion 39 of the second gripper 28.
As further shown in FIGS. 2, 4, 7, and 8, the second gripper 28 has an extension 41 on the bottom of the cylindrical neck portion 40. The extension 41 is configured to be received in a receiver 65 on the second cylindrical body 24, and serves as a means to attach the second gripper 28 to the second cylindrical body 24 to form the second member 14. The extension 41 is comprised of a resilient tab portion 42 and a flange portion 43, which is split down the middle to create a small gap 44 between the two halves of the extension 41. As a result, the tab portion 42 can be described as a pair of tabs separated by a gap 44, with each tab having a portion of the flange 43 thereon. The small gap 44 allows the two halves of the extension 41 to be squeezed together, and the tabs 42 flex inwardly to insert the extension 41 into the receiver 65 at the first end 34 of the second cylindrical body 24. Once the extension 41 is inserted into the receiver 65, the tabs 42 flex outwardly and the flange portion 43 engages an engagement surface of the receiver to keeps the second gripper 28 connected to the second cylindrical body 24 to form the second member 14. In this embodiment, the receiver 65 is formed by a narrowed opening 66 in an end wall 67 of the second cylindrical body 24, where the opening 66 receives the extension 41 and the inner surface of the end wall 67 forms the engagement surface. Each piece 29, 30 has a partial end wall with a notch 68, so that the pieces 29, 30 combine to form the receiver 41. Attachment of the second gripper 28 by the extension 41 allows the second gripper 28 to be rotated 360 degrees with respect to the second cylindrical body 24. In another embodiment, a smaller degree of rotation may be enabled, or the gripper 28 may not be rotatable.
FIG. 8A discloses an alternative embodiment of the second gripper, designated with the reference numeral 28a. It is understood that the alternative second gripper 28a could be used instated of the second gripper 28 of FIG. 8. In this embodiment, the second gripper 28 has some similar structure to the second gripper 28 of FIG. 8, and is configured for connection to the receiver 65 of FIGS. 2-4. However, the second gripper 28a of FIG. 8A has a differently configured extension 41a that extends from a bottom of the cylindrical neck portion 40a. In this embodiment, the extension 41a has a flange 43a at a distal end, and the extension 41a and flange 43a are not split and have generally solid outer peripheries. The extension 41a is inserted into the receiver 65 by laying the extension 41a in the notch 68 of one of the pieces 29 of the second cylindrical body 24 at the first end 34, similar to the position of the extension 41 in FIG. 4. Then, the other piece 30 of the second cylindrical body 24 is connected to the first piece 29. The connected pieces form the end wall 67, which functions as an engagement surface to engage the flange 43a to retain the second gripper 28a to the body 24 and form the second member 14. Appropriate sonic welding can be used at this location to secure the second gripper 28a to the second member 14 while still allowing for rotation of the second gripper 28a with respect to the second member 14. In another embodiment, the extension 41a of the second gripper 28a may have a different length or dimension, which may be accompanied by changes to the structure of the receiver 65. In a further embodiment, the second gripper 28a may have a narrower width (i.e. thinner upper sides 52) than the second gripper 28 in FIGS. 7-8, which can decrease weight and also increase ease of use. It is understood that the gripper 28a may have gripping teeth connected thereto, such as the teeth 56, 58 of the gripper 28 in FIGS. 7-8.
As shown in FIGS. 1-4 and 11-17, the first member 12 is removably connected to the second member 14 in telescoping fashion. For clarity purposes, FIG. 4A shows the first member 12 and the second member 14 with each having one piece 30, 16B removed to illustrate the cooperating internal features of the members 12, 14. Cooperation between the members 12,14 is shown schematically in FIGS. 13-17, discussed below, which illustrate the interaction between a single projection 36 of the second member 14 and a single longitudinal groove 21 and corresponding set of locking grooves 23 of the first member 12. The second end 35 of the second cylindrical body 24 of the second member 14 slides inside the hollow interior chamber 62 of the first cylindrical body 13 of the first member 12 through the end opening 63 after aligning the internal longitudinal grooves 21 of the first cylindrical body 13 with each of the projections 36 on the external surface of the second cylindrical body 24. The projections 36 fit inside the internal longitudinal grooves 21 and permit the second cylindrical body 24 to slide into the first cylindrical body 13 in a controlled fashion. FIG. 13 illustrates insertion of the second cylindrical body 24 into the chamber 62 of the first member 12 (see arrow), such that the projection 36 is located within the longitudinal groove 21. When the projection 36 is within the longitudinal groove 21, the second member 14 is axially/telescopically moveable with respect to the first member 12, and is considered to be in an adjustable position. The projection 36 can slide along the longitudinal groove 21 as the second member 14 moves axially. When the projection 36 slides completely to the end of the longitudinal groove 21 proximate the first gripper 15, the tool is in the fully contracted position. It is understood that the opposite projection 36 and corresponding opposite grooves 21, 23 are not shown in FIGS. 13-17, but the relative positioning of the opposite projection 36 and grooves 21, 23 will be approximately the same.
Once inserted, the second member 14 can be locked to the first member 12 through interaction between the projections 36 and the first set of internal locking grooves 23 within the first cylindrical body 13. The cooperative locking structure between the first and second members allows the second member 14 to be locked into a plurality of locked positions, each of which represent a different degree of extension of the tool 10. Movement to a first locking position from the adjustable position is illustrated in FIGS. 14-15, where the second member 14 is slid generally into the first member 12 until the projections 36 reach the locking grooves 23 of the fourth position L4. Then, the second member 14 is rotated in angular fashion to move the projections 36 through the horizontal portions 45 of the locking grooves 23, as shown by the arrow in FIG. 14, and the second member 14 is moved axially by pushing toward the first gripper 15 to lock the projections 36 into the vertical portions 46 of the locking grooves 23, as shown by the arrow in FIG. 15. Once the second member 14 is locked into position as shown in FIG. 15, with the projections 36 received in the locking grooves 23 of the fourth position L4, the second member 14 is considered to be in the fourth locked position. The members 12, 14 can also be placed into additional locked positions by locking into place by cooperation with the additional locking grooves 23, in positions L1-L3. FIG. 16 illustrates movement the second member 14 from the fourth locked position into the adjustable position, with the arrows indicating the movement of the projection 36. FIG. 17 illustrates movement of the second member from the adjustable position into a third locked position, with the arrows indicating movement of the projection 36 into the locking groove 23 in the third groove position L3. Movement to first and second locking positions can be accomplished by similarly moving the projections 36 into the locking grooves 23 of the first and second groove positions L1, L2, respectively. It is understood that depending on the groove position L1-L4 selected, the members 12, 14 can have a varying degree of extension, and can represent multiple extended positions. Thus, if a greater extended position is desired from L1, the projections 36 can be aligned with the locking grooves 23 at L2-L4 consistent with the description above.
FIGS. 11 and 12 illustrate different degrees of extension of the tool 10, by locking the second member 14 into different locking positions relative to the first member 12. FIG. 11 illustrates the tool 10 when the second member 14 is in the fourth locking position, when the projection 36 is locked in position L4. As shown, the distance D1 between the grippers 15, 28 is fully extended, and the grippers 15, 28 grip objects 69 to separate the objects 69. As will be appreciated, the objects 69 can be portions of a chest cavity of a carcass of a harvested animal, and this extension can be used to expand the chest cavity of the carcass. The position at L4 is the most extended position that the members 12, 14 can be locked. FIG. 12 illustrates the tool 10 when the second member 14 is in the second locking position, when the projection 36 is locked in position L2. As shown, the distance D2 between the grippers 15, 28 is smaller than the distance D1 in the fourth locking position, and the extension of the tool 10 is not as large, so that the grippers 15, 28 separate the objects 69 a smaller distance. It is understood that locking positions L1 and L3 will have further different degrees of extension.
In another embodiment, the first member 12 may have a different number of locking grooves 23, and the locking grooves may have a different shape. For example, in one embodiment, the first member 12 may have two or more locking grooves 23, and in another embodiment, the first member 12 may have only a single locking groove 23 to represent an extended position relative to a fully contracted position. As another example, the locking grooves 23 may be straight, rather than L-shaped, or may take another shape. In a further embodiment, the first and second members 12, 14 may have a different type of complementary locking structure to permit the two members 12, 14 to be locked in a plurality of different positions with respect to each other. For example, the structures may be transposed so that the first member 12 has one or more projections that lock in slots of the second member 14. In still further embodiments, additional types of locking structures may be used.
In use, the hunter may carry the tool 10 while hunting, such as in a field carry position shown in FIG. 9. In the carry position, the second end 35 of the second member 14 is inserted into the opening 64 of the first member 12 at the first grip 15, rather than the opposite end opening 63 as described above. When the hunter has obtained an animal carcass, such as a deer, and cuts open its chest, the hunter can take out the tool 10 and insert it into the chest cavity in its fully contracted position. Once the tool 10 is inserted into the carcass, the hunter can extend the tool 10 into one of the extended locking positions as to expand the chest cavity as wide as necessary in order to clean the carcass. It is understood that in one embodiment, the tool 10 may have only a single extended locking position, as described above. At the desired extended position, the hunter can lock the tool 10 into place by twisting the second member 14 to fit into the projections 36 into the desired locking grooves 23 in the first member 12, e.g., L1, L2, L3, L4, as described above. The sharp protrusions 22, 25 on the integral first gripper 15 and the sharp protrusions 56,58 on the attached second gripper 28 stick into the carcass to aid in holding the tool 10 in place. The rotatable nature of the attached second gripper 28 on the second member 14 allows the hunter to adjust the second gripper 28 as necessary. When the tool 10 is firmly in place, the hunter is able to cool, clean and harvest the carcass to prepare it for further processing. Once complete, the tool 10 can be returned to its fully contracted position, in which the projections 36 are past the locking grooves at L1, and removed from the carcass. The members 12,14 can also be separated and then one member re-inserted into the other member as shown in FIG. 9, which represents the carry position. The tool 10 can be cleaned at a later time.
The members 12, 14 of the tool 10, including some or all components thereof, can be made from a variety of different materials, including metals, polymers, composites, ceramics, wood, etc., or a combination of such materials. Additionally, the components can be formed using any known method or technique or combination of such techniques, which may depend on the type of material, including without limitation: casting, molding, machining, and other forming methods. In one embodiment, the components of the members 12, 14 are polymer parts produced by injection molding, and may be made from acetal polymers or copolymers, or other polymer materials.
FIGS. 10 and 11 disclose an additional alternative embodiment of the tool 10 of the present invention. It is understood that other structures and aspects of the tool 10 as described above generally are applicable to the embodiment of FIGS. 10 and 11. Particular differences will be discussed regarding FIGS. 10 and 11 and common or similar structures described above will be designated with similar reference numerals in the “1xx” series.
As can be appreciated from FIG. 10, a second member 114 has a second cylindrical body 124 for attachment to a second gripper 128. The second member 114 will be comprised of three pieces, with the cylindrical body having two pieces 129, 130, and the second gripper 128. The pieces 129, 130 have complementary pins 131 and holes 132 along the edges 133, to allow the pieces 129, 130 to be connected to form the second cylindrical body 124, as similarly described above. The second member 114 also has a receiver 165 formed by a cylindrical opening 166 in an end wall 167 of the second cylindrical body 124, formed by the combination of the two pieces 129, 130, as similarly described above. The cylindrical opening 166 of the receiver 165 will cooperate with the attachable second gripper 128 as described below. Other structures of the piece shown in FIG. 10 to form the second member will be similar to those described above.
As shown in FIG. 10, the alternative second gripper 128 is an attachable piece to the second cylindrical body 124. The second gripper 128 has similar gripper structure to the gripper 28 shown in FIGS. 7-8. As further shown in FIG. 10, the second gripper 128 has an extension in the form of a finger 141 on the bottom of a cylindrical neck portion 140. The finger 141 is configured to be received in the receiver 165 of the second cylindrical body 124 and serves as a means to attach the second gripper 128 to the second cylindrical body 124 to form the second member 114. In an exemplary embodiment, the finger 141 is a simple cylindrical member that extends from the cylindrical neck portion 140. The finger 141 is sized to fit into the cylindrical opening 166 of the receiver 165. Thus, the second gripper 128 is connected to the second member simply by inserting the finger 141 into the cylindrical opening 165. It is understood that the finger 141 can rotate within the cylindrical opening 133, such that the second gripper 128 can rotate 360 degrees with respect to the second member 114. In this embodiment, it is further understood that the second gripper 128 is not more permanently secured to the second member. The second gripper 128 can be separated from the second member by pulling the second gripper 128 from the second member 114 so that the finger 141 is removed from the cylindrical opening 166. In this embodiment, no structure is provided to permanently attach the second gripper 128 to the second cylindrical body 124. It is understood, however, the receiver 165 and the finger 141 could be cooperatively dimensioned to provide an interference fit therebetween while still allowing the finger 141 to be pulled out of the cylindrical opening 166 and also rotated. It is understood that the second member 114 of FIG. 10 can be used with the first member 12 as shown in FIGS. 1-4 and described above.
The tool 10 can be used to cool an animal's chest cavity after cleaning/dressing and during transport, as well as during cleaning/dressing of an animal, to provide greater access to the chest cavity. The tool 10 provides several benefits. First, the tool 10 is lightweight to allow for easy portability. Second, the field carry position shown in FIG. 9 allows the tool to take up less space during transport. Third, the presence of the locking grooves within the first member 12 of the tool 10 provides the hunter the ability to extend and lock the tool at several different lengths (positions L1-L4) to account for the different sizes in chest cavities of animal carcasses. Finally, the rotatable attached second gripper 28 allows the hunter to adjust the tool 10 inside the animal carcass to obtain a sturdier grip. In addition, the tool 10 can be made generally from injected-molded materials providing for easy and efficient manufacture, as well as light weight. The tool 10 can also be easily cleaned for future uses.
