CROSS-REFERENCE TO RELATED APPLICATIONS

This application relates to U.S. patent application Ser. No. 14/340,086 filed on Jul. 24, 2014, now US Patent Application Publication US 2014/0331982 A1, by G. Gouramanis, which is a continuation of U.S. patent application Ser. No. 13/109,325 filed on May 17, 2011, now U.S. Pat. No. 8,789,518, “UNIVERSAL ARCHERY BOW PRESS”, by G. Gouramanis, the entire contents of both of which are incorporated herein by reference.

BACKGROUND

Technical Field

The present disclosure relates generally to devices and apparatuses for archery bow service and maintenance, and more particularly for the support of archery bows while being pressed.

Description of Related Art

Archery bow presses are used in the maintenance of archery bows, and in particular, are necessary for the customization of compound bows, where force is required to press the bow in order to service it.
Typically, bow presses are not equipped with any bow limb support mechanisms due to the design of existing bows. However, the acceleration of new, high-tech extreme bow designs demands the need for a mechanism to hold the bow in place when it is being pressed. Existing bow presses provide little to no support to the bow while extreme pressure is being put on the limbs.
Pressing these new and advanced bows without supporting the limbs is a dangerous and risky process, as it poses a potential safety threat to the operator and the possibility of damage to the bow.

SUMMARY

The embodiments of the present disclosure advance the state of the art by providing a bow limb support apparatus as the bow is pressed from its tips, thereby reducing the chances of the bow slipping out of the press and causing harm to the operator and damage to the bow.
Accordingly, the present disclosure relates to two sets of components used during the bow pressing process, which prevent: 1) the bow from slipping out of the press, 2) damage to the bow and 3) injury to the operator, while the bow is under extreme pressure.
One aspect of the disclosure is to provide support and safety to the bow pressing process for various types and sizes of archery compound bows. It is done in an easy and efficient manner by maintaining control of the bow during a pressing operation. The presently disclosed bow limb support apparatuses offer a quick and safe means to effectively assist in pressing operations on a compound bow reducing risk of damage or injury. The bow limb support apparatuses can be mounted to an existing bow press by securing a mounting clamp mechanism to each side of the press, or the bow limb support apparatuses can be included in the original bow press design.
A bow limb support apparatus is disclosed including a mounting clamp mechanism having provisions to be attached to each side of a bow press and a knob in order to secure the sliding shaft.
The bow limb support apparatus also includes a sliding shaft used in order to easily adjust to different archery bows by sliding the bow limb support apparatus in and out.
The bow limb support apparatus includes a spring retainer attached to one end of the shaft.
The bow limb support apparatus also includes multiple springs and fasteners to provide the support apparatus with the capability to flex under pressure.
The bow limb support apparatus also includes a bow limb interfacing support member, which is spring-loaded to allow the bow limbs to flex when they are being pressurized and provides support, tending to prevent the bow from slipping out of the press. The bow limb interfacing support member is made from composite material to prevent damage to the bow limbs upon contact. The spring-loaded aspect of the bow limb interfacing support member is an important feature relating to the ultimate function of the bow limb support apparatus.
A set of two bow limb support apparatuses (one on one bow limb and one on the other bow limb) generally provides full support to the bow when it is being pressurized.

DETAILED DESCRIPTION

In the Summary and Brief Description of the Drawings sections above, in this Detailed Description, in the Claims below, and in the accompanying drawings, reference is made to particular features (including method steps or acts) of the present disclosure. It is to be understood that the disclosure in this specification includes combinations of parts, features, or aspects disclosed herein. For example, where a particular feature is disclosed in the context of a particular aspect or embodiment of the present disclosure, or a particular claim, that feature can also be used, to the extent possible, in combination with and/or in the context of other particular aspects and embodiments of the present disclosure, and in the disclosure generally.
The term “comprises” and grammatical equivalents thereof are used herein to mean that other components, ingredients, steps, acts, etc. are optionally present. For example, an article “comprising (or “which comprises”) component A, B, and C can consist of (i.e., contain only) components A, B, and C, or can contain not only components, A, B, and C but also one or more additional components, elements, features, ingredients, steps, acts, etc.
Where reference is made herein to a method comprising two or more defined steps or acts, the defined steps or acts can be carried out in any order or simultaneously (except where the context excludes that possibility); and the method can include one or more other steps or acts which are carried out before any of the defined steps or acts, between two of the defined steps or acts, or after all the defined steps or acts (except where the context excludes that possibility).
The term “at least” means one or more than one. When, in this specification, a range is given as “(a first number) to (a second number)” or “(a first number) (a second number),” this means a range whose lower limit is the first number and whose upper limit is the second number. For example, 25 mm to 100 mm means a range whose lower limit is 25 mm, and whose upper limit is 100 mm.
Disclosed herein is a limb guard mechanism which provides for a safe and effective way of supporting the limbs of an archery bow while being pressed. As used herein, the term “bow” includes any type of bow currently in use, including, for example, longbows, recurve bows, compound bows, etc. The term “limb” as used herein includes the upper and lower parts of a working bow where all the energy is being stored, and may include several designs, such as a solid limb or split limb.
Typically, any bow, new or used, will need to be customized to the archer that will ultimately use it. That includes correct draw length with draw stops, desired draw weight, peep sights, and off-setting cams to clear cables. For this process, it is necessary to press the bow limbs in order to relax the strings. When the bow is pressed, and the strings and cables are removed, the bow press is actually holding the bow and all of its stored energy. While the limbs are compressed in this way, the present disclosed bow limb support apparatus secures the bow in place and safely perform maintenance.
FIGS. 1-4 illustrate an archery bow limb support apparatus 1100 a for supporting the limbs of an archery bow (not shown) during pressing according to one embodiment of the present disclosure.
As best shown in FIG. 1, the bow limb support apparatus 1100 a includes a bow limb interfacing support member 1105 that defines a directional plane of contact A-A with a bow limb (not shown)
The bow limb support apparatus 1100 a includes a bow limb interfacing support shaft member assembly 1125 that includes a shaft 1126 that defines an axis X-X that extends from a proximal end defined generally as a bow press end 1125 a to a distal end 1125 b defined as a bow limb end.
The bow limb interfacing support shaft member assembly 1125 is in operative communication with the bow limb interfacing support member 1105 and is configured and disposed to define an angle θ that is less than 180 degrees between the directional plane of contact A-A of the bow limb interfacing support member and the axis X-X of the shaft 1126 of bow limb interfacing support shaft member assembly 1125, In the example of the bow limb support apparatus 1100 a of FIGS. 1-4, the axis X-X is a longitudinal axis of the bow limb interfacing support shaft member assembly 1125.
The bow limb interfacing support member 1105 defines a symmetrical U-shaped cross section 1106 with respect to the plane of contact A-A. An internal volume 1108 is defined in the U-shape.
The bow limb interfacing support shaft member assembly 1125 includes a bow limb interfacing support member force transmittal member 1130 that is disposed at the distal end 1125 b of the shaft 1126.
The internal volume 1108 is configured and disposed to at least partially receive the bow limb interfacing support member force transmittal member 1130 therewithin.
The bow limb interfacing support shaft member assembly 1125 further includes a locking mechanism 1140 in proximity to the proximal end 1125 a that is defined generally as the bow press end. Locking mechanism 1140 may be a solid block of material 1141 that defines an internal volume 1142 extending therethrough from a side 1142′ of the locking mechanism 1140 that interfaces with the proximal end 1125 a to a side 1142″ that interfaces with the distal end 1125 b. In the example embodiment of FIGS. 1-4, the internal volume 1142 is cylindrically shaped. The shaft 1126 may also be cylindrically shaped except for a flat surface 1126′ along the length of the shaft. The shaft 1126 is received within the internal volume 1142 such that the locking mechanism 1140 is movable along the axis X-X of the shaft 1126.
The locking mechanism 1140 is illustrated in FIGS. 1-4 as a generic locking mechanism intended to secure a bow press to the archery bow limb support apparatus 1100 a and described herein in that manner. Locking mechanisms that are specifically configured and disposed to secure a bow press to the archery bow limb support apparatus 1100 a during pressing of an archery bow (e.g., a custom locking mechanism) are described in further detail below with respect to FIGS. 15A-22C.
The locking mechanism 1140 is movable along the axis X-X of the shaft 1126. To secure the locking mechanism 1140 to a desired position on the shaft 1126, the locking mechanism 1140 includes a locking knob 1144 and, as best shown in FIG. 4, a knob securing passage 1146 that is configured and disposed to penetrate from the exterior of the locking mechanism block shape to the internal volume 1142 of the locking mechanism. The locking knob 1144 further includes a threaded rod 1148 attached thereto which advances and retracts within the knob securing passage 1146 as a user turns the locking knob. When the locking knob 1144 has fully advanced the threaded rod 1148, the threaded rod contacts the flat surface 1126′ of the shaft 1126 to secure the desired position of the locking mechanism 1140 on the shaft 1126. Additionally, the flat surface 1126′ assists in assuring proper orientation of the shaft 1126 and the bow limb interfacing support member 1105.
The archery bow limb support apparatus 1100 a further includes at least one energy transfer member 1110 a, and additionally may include as shown in FIG. 4 energy transfer members 1110 b 1 and 1110 b 2 that are each configured and disposed to transmit a force applied by a bow limb to the bow limb interfacing support member 1105 through the energy transfer members 1110 a, 1110 b 1 and 1110 b 2 to the bow limb interfacing support member force transmittal member 1130 to the bow limb interfacing support shaft member assembly 1125 to support a bow limb.
The one or more energy transfer members 1110 a, 1110 b 1 and 1110 b 2 are at least partially disposed in the internal volume 1108 defined by the bow limb interfacing support member 1105.
As best illustrated in FIGS. 4 and 5A, the one or more energy transfer members 1110 a, 1110 b 1, 1110 b 2 may include one or more springs disposed at least partially within the internal volume 1108 such that one end 1110 a′, 1110 b 1′, 1110 b 2′ of the energy transfer members or springs 1110 a, 1110 b 1, 1110 b 2 is received in energy member support cavities or recesses 1105 a, 1105 b 1, 1105 b 2, respectively, defined in and disposed in the bow limb interfacing support member 1105 interfacing the internal volume 1108. Another end 1110 a″, 1110 b 1″, 1110 b 2″ of the energy transfer members or springs 1110 a, 1110 b 1, 1110 b 2 is received in energy member support cavities or recesses 1130 a, 1130 b 1, 1130 b 2, respectively, defined in and disposed in the bow limb interfacing support member force transmittal member 1130 and also interfacing the internal volume 1108. Thereby, the energy transfer members or springs 1110 a, 1110 b 1, 1110 b 2 enable operative communication between the bow limb interfacing support member force transmittal member 1130 and the bow limb interfacing support member 1105.
As illustrated in FIGS. 1 and 5A, the U-shaped bow limb interfacing support member 1105 defines an internal surface 1105′ in the internal volume 1108 at the base of the U which interfaces with upper surface 1130′ of the bow limb interfacing support member force transmittal member 1130 within the internal volume 1108. The interfacing of the upper surface 1130′ with respect to the internal surface 1105′ is maintained by securing members 1112 a and 1112 b, shown for example in the form of threaded bolts, that are disposed on either side of the energy transfer members 1110 b 1 and 1110 b 2, respectively. The securing members 1112 a and 1112 b extend from proximal ends 1116 a and 1116 b of body portions 1132 a and 1132 b through passageways 1134 a and 1134 b that are formed within the bow limb interfacing support member force transmittal member 1130 and disposed on either side of the energy transfer members 1110 b 1 and 1110 b 2, respectively. The body portions 1132 a and 1132 b extend distally to distal ends 1114 a and 1114 b that are shown as threaded ends that mesh with a threaded surface within internal volumes 1107 a and 1107 b formed within the bow limb interfacing support member 1105, again on either side of the energy transfer members 1110 b 1 and 1110 b 2, respectively.
FIG. 5B illustrates a bow limb 1000 a of an archery bow that is in contact with the bow limb interfacing support member 1105 during pressing of an archery bow. Since the bow limb interfacing support member force transmittal member 1130 remains generally stationary by the bow limb interfacing support shaft member assembly 1125, the bow limb 1000 a and the bow limb interfacing support member force transmittal member 1130 exert a dual direction force F and the bow limb interfacing support member 1105 tends to move in the direction of arrow A towards a compressed position represented by dashed line 1105Y1. Since the distal ends 1114 a and 1114 b of the securing members 1112 a and 1112 b are meshed to the threaded surface of the internal volumes 1107 a and 1107 b while the body portions 1132 a and 1132 b are free to move through passageways 1134 a and 1134 b, the proximal ends 1116 a and 1116 b of the securing members 1112 a and 1112 b are free to move proximally towards a corresponding compressed position represented by dashed line 1116Y1. The differential distance between the uncompressed position of the internal surface 1105′ and the dashed line 1105Y1 is ΔY1. Similarly, the differential distance between the uncompressed position of the proximal ends 1116 a and 1116 b and the dashed line 1116Y1 is also ΔY1. As indicated above, the orientation of the flat surface 1126′ of the shaft 1126 assists in assuring that the bow limb 1000 a is properly supported by archery bow limb support apparatus 1100 a.
FIG. 5C illustrates the bow limb interfacing support member 1105 when it has actually moved the differential distance ΔY1 in the direction of the arrow A as a result of the force F. Since the bow limb interfacing support member 1105 is mobile with respect to the generally stationary bow limb interfacing support member force transmittal member 1130, upper surface 1105″ of the bow limb interfacing support member 1105 moves the same differential distance ΔY1 in the direction of the arrow A while the internal surface 1105′ moves the same differential distance ΔY1 to the compressed position represented by dashed line 1105Y1 shown in FIG. 5B. Similarly, the body portions 1132 a and 1132 b of the securing members 1112 a and 1112 b are free to move the same differential distance ΔY1 through passageways 1134 a and 1134 b, respectively, to the compressed position represented by dashed line 1116Y1 shown in FIG. 5B.
FIG. 5D illustrates an extreme position, not generally occurring in actual usage of the bow limb support apparatus 1100 a wherein the energy transfer members 1110 a, 1110 b 1 and 1110 b 2 are compressed to a maximum condition by the bow limb 1000 a and/or the bow press such that the internal surface 1105′ has moved a differential distance ΔY2 to a further compressed position wherein the internal surface 1105′ and the upper surface 1130′ of the bow limb interfacing support member force transmittal member 1130 are in contact with one another. As expected, upper surface 1105″ of the bow limb interfacing support member 1105 moves the same differential distance ΔY2 in the direction of the arrow A while the body portions 1132 a and 1132 b of the securing members 1112 a and 1112 b are free to move the same differential distance ΔY2 through passageways 1134 a and 1134 b, respectively, to the further compressed position.
The bow limb interfacing support member 1105 may be made from a composite material such as acetyl homopolymer resin, known as Delrin® (a registered trademark of the DuPont de Nemours Co., Wilmington, Del., USA). The bow limb interfacing support shaft member assembly 1125 generally may be made from a metallic material such as steel, e.g., AISI 303 stainless steel, to facilitate welding and rigid joining between the bow limb interfacing support member force transmittal member 1130 and shaft 1126.
FIGS. 6-14 illustrate another embodiment of the bow limb support apparatus 1100 a. More particularly, bow limb support apparatus 1100 b is identical to bow limb support apparatus 1100 a except that now bow limb support apparatus 1100 b is a mirror image of bow limb support apparatus 1100 a described above with respect to FIGS. 1-5D. Accordingly, as opposed to bow limb support apparatus 1100 a wherein the proximal end 1125 a of the bow limb interfacing support shaft member assembly 1125 is shown on the left side of the paper and extending to the distal end 1125 b on the right side of the paper, for bow limb support apparatus 1100 b, the proximal end 1125 a is now shown on the right side of the paper and extending to the distal end 1125 b on the left side of the paper. Instead of flat surface 1126′, the shaft 1126 now includes a flat surface 1126″ that is configured and disposed on the opposite side of the shaft 1126 with respect to flat surface 1126′.
Locking mechanism 1140 is identical but is now repositioned such that the locking knob 1144, knob securing passage 1146 and threaded rod 1148 enable the threaded rod 1148 to contact the flat surface 1126″. In a similar manner, when the locking knob 1144 has fully advanced the threaded rod 1148, the threaded rod now contacts the flat surface 1126″ of the shaft 1126 to secure the desired position of the locking mechanism 1140 on the shaft 1126. Structurally, all of the parts and configuration of the bow limb support apparatus 1100 b are identical to bow limb support apparatus 1100 a except for the difference of the location of flat surfaces 1126′ and 1126″. In fact, if shaft 1126 is manufactured with both flat surface 1126′ and flat surface 1126″, bow limb support apparatus 1100 b would be identical and interchangeable with bow limb support apparatus 1100 a, with the exception of the orientation of the locking mechanism 1140 and the locking knob 1144 securing the flat surface 1126″. There would however be a reduction in desirable frictional resistance between the shaft 1126 and the interior surface of the internal volume 1142. In a similar manner as indicated above, the orientation of the flat surface 1126″ of the shaft 1126 assists in assuring that a bow limb is properly supported by archery bow limb support apparatus 1100 b.
FIGS. 15A-15F illustrate a bow press 100 that is generally identical to that described in US Patent Application Publication US 2014/0331982 A1, “UNIVERSAL ARCHERY BOW PRESS”, by G. Gouramanis, which is incorporated by reference. Bow press 100 differs from that described therein in that bow press 1200 now includes the bow limb support apparatuses 1100 a and 1100 b as described above. The bow press 100 design and operation are not described in detail herein except as required to describe the interface with the bow limb support apparatuses 1100 a and 1100 b. The bow press 100 is mounted on a stand 102 with vertical supports 104 a and 104 b for telescoping shaft 106. The telescoping shaft 106 includes on opposite ends supporting arms 110 a and 110 b. The supporting arms 110 a and 110 b support mounting assemblies 112 a and 112 b, respectively. The mounting assemblies 112 a and 112 b include structural channel members 114 a and 114 b defining internal passages 116 a and 116 b therethrough and upper apertures 116 a′ and 116 b′ and lower apertures 116 a″ and 116 b″ to the internal passages 116 a and 116 b, respectively. The mounting assemblies 112 a and 112 b are received in the structural channel members 114 a and 114 b via the upper apertures 116 a′ and 116 b′ and are secured to the structural channel members 114 a and 114 b via securing members 118 a and 118 b, e.g., screws or threaded bolts, that penetrate through walls 1212 and 1214 of the structural channel members 114 a and 114 b, respectively.
FIGS. 15D-15F illustrate a locking mechanism 1240 that is specifically configured and disposed to interface with the supporting arms 110 a and 110 b and structural channel members 114 a and 114 b via securing members 120 a and 120 b. Locking mechanism 1240 is illustrated as substituting for generic locking mechanism 1140 and is a locking mechanism that, as described above with respect to FIGS. 1-14, is configured and disposed to secure bow press 100 to the archery bow limb support apparatuses 1100 a and 1100 b during pressing of an archery bow. More particularly, locking mechanism 1240 is configured to be received within the internal passages 116 a and 116 b via the lower apertures 116 a″ and 116 b″, respectively.
Referring further to FIGS. 16A-16F through FIG. 20, in a similar manner as generic locking mechanism 1140, locking block 1241 of locking mechanism 1240 may also be a solid block of material that defines, in a lower portion of the block 1241, an internal volume 1242 extending therethrough from a side 1242′ of the locking mechanism 1240 that interfaces with the proximal end 1125 a of shaft 1125 to a side 1242″ that interfaces with the distal end 1125 b of the shaft 1125. Again, in the example embodiment of FIGS. 15A-20, the internal volume 1242 is cylindrically shaped. Similarly, the shaft 1126 may also be cylindrically shaped except for flat surface 1126′ along the length of the shaft. The shaft 1126 is received within the internal volume 1242 such that the locking mechanism 1240 is movable along the axis X-X of the shaft 1126.
The locking block 1241 further defines, in an upper portion of the block 1241, another internal volume 1252 extending therethrough again from side 1242′ of the locking mechanism 1240 that interfaces with the proximal end 1125 a of shaft 1125 to side 1242″ that interfaces with the distal end 1125 b of the shaft 1125.
The locking block 1241, generally in the form of a rectangular block, includes an upper surface 1262 in the form of a square with rounded corners which may include at each corner apertures 1262 a, 1262 b, 1262 c and 1262 d. The locking block 1241 further includes four longitudinal surfaces 1264 a, 1264 b, 1264 c, 1264 d such that shaft receiving internal volume 1242 extends from aperture 1242′ on surface 1264 b to aperture 1242″ on surface 1264 d.
As further illustrated in FIGS. 17, 18A-18E, 19 and 20, the locking mechanism 1240 also includes, in a similar manner as locking mechanism 1140, the locking knob 1144 and, as best shown in FIGS. 18A-18E, knob securing passage 1146 that is configured and disposed to penetrate from the exterior of the locking mechanism block shape on longitudinal surface 1264 a to the internal volume 1242 of the locking mechanism 1240. The locking knob 1144 again further includes threaded rod 1148 attached thereto which advances and retracts within the knob securing passage 1146 as a user turns the locking knob. When the locking knob 1144 has fully advanced the threaded rod 1148, the threaded rod contacts the flat surface 1126′ of the shaft 1126 to secure the desired position of the locking mechanism 1240 on the shaft 1126.
As best shown in FIGS. 15F and 19, as described above, structural channel members 114 a and 114 b define internal passages 116 a and 116 b therethrough and upper apertures 116 a′ and 116 b′ and lower apertures 116 a″ and 116 b″ to the internal passages 116 a and 116 b, respectively. The structural channel members 114 a and 114 b include apertures 1212′ and 1212″ in wall 1212 and apertures 1214′ and 1214″ in wall 1214 that enable the securing members 118 a and 118 b and securing members 120 a and 120 b to be received therein, respectively, to secure the locking blocks 1241 to the structural channel members 114 a and 114 b, respectively, after the upper surface 1262 and upper portion of the locking blocks 1241 are received through the lower apertures 116 a″ and 116 b″ and the securing member receiving internal volume 1252 and apertures 1252′ and 1252″ are aligned with apertures 1212′ and 1212″, respectively.
Returning to FIGS. 16A-16F, in addition to the locking block 1241 optionally including at each corner apertures 1262 a, 1262 b, 1262 c and 1262 d, adjacent to and parallel to the securing member internal volume 1252 and corresponding apertures 1252′ and 1252″ may also be disposed internal volumes 1254 and 1256 that extend from apertures 1254′ and 1256′ in longitudinal surface or wall 1264 b to apertures 1254″ and 1256″ in longitudinal surface or wall 1264 d, respectively. Further, on the lower portion of longitudinal surface or wall 1264 c opposite the knob securing passage 1146 on longitudinal surface or wall 1264 a there may also be defined a pair of apertures and internal volumes 1258′ and 1258″ wherein aperture and internal volume 1258′ is disposed above the knob securing passage 1146 and aperture and internal volume 1258″ is disposed below the knob securing passage 1146.
The purpose of the corner apertures 1262 a, 1262 b, 1262 c and 1262 d, internal volumes 1254 and 1256 that extend from apertures 1254′ and 1256′ and apertures and internal volumes 1258′ and 1258″ is to enable the locking mechanism 1241 and therefore the bow limb support apparatuses 1100 a and 1100 b to interface with other types of bow presses that are not described herein.
FIG. 20 illustrates an archery bow 1000 with bow limbs 1000 a (see FIG. 5B) and 1000 b supported by the bow limb support apparatuses 1100 a and 1100 b disposed in bow press 100 as described above. Those skilled in the art will recognize that bow press 100 and the one or more bow limb support apparatuses 1100 a and 1100 b are included within an archery bow press and bow limb support system 500 for supporting the limbs of an archery bow during pressing. Accordingly, the archery bow press and bow limb support system 500 includes the bow press 100 and at least one archery bow limb support apparatus, e.g., bow limb support apparatuses 1100 a and/or 1100 b, for supporting the limbs of an archery bow, e.g., bow limbs 1000 a and 1000 b of archery bow 1000 during pressing. Once archery bow 1000 is secured in the bow press 100 via the bow limb support apparatuses 1100 a and/or 1100 b, an operator is ready to compress the bow 100 to relax the strings and cables. The bow limb support apparatuses 1100 a and/or 1100 b provide support for the bow 100 to stay securely in place in the archery bow press and bow limb support system 500 while maintenance is performed.
Additionally, referring again to FIG. 5B in conjunction with at least FIG. 20, those skilled in the art will recognize and understand that the one or more one energy transfer members, e.g. energy transfer members 1110 a, 1110 b 1 and 1110 b 2, may also be configured and disposed to transmit dual direction force F as a force applied by the bow limb interfacing support shaft member 1125 a and/or 1125 b to the bow limb interfacing support member force transmittal member 1130 to the bow limb interfacing support member 1105 to support bow limb 1000 a and/or 1000 b.
FIGS. 21A-21F illustrate another locking mechanism 1340 that is specifically configured and disposed to interface with an extension arm of another type of bow press 200 illustrated in FIGS. 22A-22C. Again, the locking mechanism 1340 is illustrated as substituting for generic locking mechanism 1140 and is a locking mechanism that, as described above with respect to FIGS. 1-14, is configured and disposed to secure archery bow limb support apparatuses 1100 a and 1100 b to bow press 200 for pressing of an archery bow.
More particularly, referring first to FIG. 22A, bow press 200 also includes the bow limb support apparatuses 1100 a and 1100 b as described above. Again, the bow press 200 design and operation are not described in detail herein except as required to describe the interface with the bow limb support apparatuses 1100 a and 1100 b. The bow press 200 is mounted with vertical supports 204 a and 204 b for telescoping shaft 206. The telescoping shaft 206 includes on opposite ends extension arms 210 a and 210 b that are disposed at right angles to the telescoping shaft 206. The bow press 200 is illustrated as a generic bow press and may include other features not described herein that may include additional supports that assist in pressing the limbs of an archery bow.
Returning to FIGS. 21A-21F, in a similar manner as generic locking mechanism 1140, locking block 1341 of locking mechanism 1340 may also be a solid block of material that defines, in a lower portion of the block 1341, internal volume 1342 extending therethrough from an aperture 1342′ on side wall 1364 b of the locking mechanism 1340 that interfaces with the proximal end 1125 a of shaft 1125 to an aperture 1342″ on side wall 1364 d that interfaces with the distal end 1125 b of the shaft 1125. Again, in the example embodiment of FIGS. 21A-22C, the internal volume 1342 is cylindrically shaped. Again, the shaft 1126 may also be cylindrically shaped except for flat surface 1126′ along the length of the shaft. The shaft 1126 is again received within the internal volume 1342 such that the locking mechanism 1340 is movable along the axis X-X of the shaft 1126.
The locking block 1341 includes an upper surface 1362 that defines a C-shaped or U-shaped cross-section forming an open channel in the locking block 1341 with a first raised linear projection or wall 1362′ and a second raised linear projection or wall 1362″ that are parallel to one another. The locking mechanism 1340 further includes first and second clamping members 1366 and 1368 that are movably secured to, and raised above, the first and second raised linear projections or walls 1362′ and 1362″ via adjustable securing members 1366′, 1366″ and 1368′, 1368″, respectively. The first and second clamping members 1366 and 1368 are positioned or disposed orthogonally with respect to the linear projections or walls 1362′ and 1362″. The adjustable securing members 1366′ and 1366″ are positioned at opposite ends of the first clamping member 1366 and on the linear projections or walls 1362′ and 1362″ in positions that are proximal to locking knob 1144 on vertical side or wall 1364 a of the locking block 1341. Similarly, the adjustable securing members 1368′ and 1368″ are positioned at opposite ends of the second clamping member 1368 and on the linear projections or walls 1362′ and 1362″ in positions that are distal to locking knob 1144 on opposite vertical side or wall 1364 c of the locking block 1341. Vertical side or wall 1364 c forms a rear wall of the locking block 1341 with respect to the locking knob 1144.
Turning again to FIG. 22A, bow limb support apparatuses 1100 a and 1100 b now each include the locking mechanism 1340 in place of generic locking mechanism 1140. The bow limb support apparatuses 1100 a and 1100 b are now mounted to extension arms 210 a and 210 b via the locking mechanism 1340. The extension arms 210 a and 210 b may have a generally square or rectangular cross-section. When the clamping members 1366 and 1368 are in a raised position (FIG. 22C) or entirely separated from the locking block 1341 (FIG. 22B), the bow limb support apparatuses 1100 a and 1100 b may be mounted under the respective extension arms 210 a and 210 b. As shown in FIG. 22B, the clamping members 1366 and 1368 and respective adjustable securing members 1366′ and 1366″ and 1368′ and 1368″ can then secure the locking block 1341 to the respective extension arms 210 a and 210 b. The securing members 1366′ and 1366″ and 1368′ and 1368″ may be in the form of adjustable threaded screws or bolts as is known in the art.
The bow press 200, with the inclusion of an archery bow such as archery bow 1000 having bow limbs 1000 a and 1000 b illustrated in FIG. 20, may then be operated in a similar manner as described above with respect to bow press 100. Thus, the bow press 200 and the bow limb support apparatuses 1100 a and 1100 b also may be included within an archery bow press and bow limb support system analogous to archery bow press and bow limb support system 500 for supporting the limbs of an archery bow during pressing.
Again, in a similar manner as described above with respect to bow press 100, once archery bow 1000 is secured in the bow press 200 via the bow limb support apparatuses 1100 a and/or 1100 b, an operator is ready to compress the bow 100 to relax the strings and cables. The bow limb support apparatuses 1100 a and/or 1100 b provide support for the bow 100 to stay securely in place in the archery bow press and bow limb support system (analogous to system 500 illustrated in FIG. 20) while maintenance is performed.
Those skilled in the art will recognize that the foregoing description of FIGS. 1-22C also describes a method for supporting the limbs of an archery bow during pressing, e.g., archery bow 1000 and bow limbs 1000 a and 1000 b. The method includes providing a bow press, e.g., bow press 100 or 200, and at least one archery bow limb support apparatus, e.g., bow limb support apparatus 1100 a for supporting the limbs of the archery bow during pressing. The archery bow limb support apparatus 1100 a includes the bow limb interfacing support member, e.g., bow limb interfacing support member 1105 that defines a directional plane of contact A-A with a bow limb and a bow limb interfacing support shaft member defining an axis extending from a proximal end defined generally as a bow press end to a distal end defined as a bow limb end, e.g., bow limb interfacing support shaft member assembly 1125 as described above.
The method includes positioning the bow limb interfacing support shaft member assembly 1125 in operative communication with the bow limb interfacing support member 1105 to define an angle less than 180 degrees between the directional axis of contact A-A of the bow limb interfacing support member 1105 and the axis X-X of the bow limb interfacing support shaft member assembly 1125.
The method further includes positioning an archery bow having first and second limbs in the bow press, e.g., positioning archery bow 1000 having bow limbs 1000 a and 1000 b in bow press 100 or 200. Additionally, the method includes interfacing the archery bow limb support apparatus 1100 a with the bow press 100 or 200 and with at least the first bow limb 1000 a thereby supporting the first bow 1000 a limb in the bow press 100 or 200 and pressing the limbs 1000 a and 1000 b of the archery bow 1000.
The method may further include providing a second archery bow limb support apparatus, e.g., archery bow limb support apparatus 1100 b, for supporting the limbs of the archery bow 1000 during pressing. Additionally, for both the first and second archery bow limb support apparatuses, e.g., bow limb support apparatuses 1100 a and 1100 b, the method may further include positioning the bow limb interfacing support shaft member, e.g. bow limb interfacing support shaft member assembly 1125, in operative communication with the bow limb interfacing support member, to define an angle less than 180 degrees between the directional axis of contact A-A of the bow limb interfacing support member 1105 and the axis X-X of the bow limb interfacing support shaft member assembly 1125. The method may further include positioning the archery bow having first and second limbs, e.g., archery bow 1000 with limbs 1000 a and 1000 b in the bow press, e.g. bow press 100 or 200.
The method may further include interfacing the first archery bow limb support apparatus with the bow press and with the first bow limb thereby supporting the first bow limb in the bow press, e.g., first archery bow limb support apparatus 1100 a with the bow press 100 or 200 and with the first bow limb 1000 a thereby supporting the first bow limb 1000 a in the bow press 100 or 200 and interfacing the second archery bow limb support apparatus 1100 b with the bow press 100 or 200 and the second bow limb 1000 b. During pressing of the limbs of the archery bow, the second archery bow limb support apparatus interfaces with the bow press and bow limb during pressing of the limbs of an archery bow, e.g., the second archery bow limb support apparatus 1100 b interfaces with the bow press 100 or 200 and bow limb 1000 a during pressing of the limbs of an archery bow.
Although the present disclosure has been described in considerable detail with reference to certain embodiments, other embodiments and versions are possible and contemplated. Therefore, the spirit and scope of the appended claims should not be limited to the description of the embodiments contained herein.
