DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
A crossbow disclosed herein may include one or more receptacles in a side of the crossbow's stock configured to receive a portion of a cocking device, and a bore through a rear portion of the stock configured to receive a spool of the cocking device. The crossbow stock may also include a cover pivotally connected to the rear portion of the stock. When closed, the cover may block access to the bore. In a storage position, a component of the cocking device may be secured to the receptacle. In a cocking position, the spool of the cocking device may be rotatably disposed within the bore.
FIG. 1 illustrates one embodiment of a crossbow with storage for a cocking device. Crossbow 2 includes stock 4 extending from front portion 5 to rear portion 6. Crossbow 2 may also include a riser assembly operatively mounted to front portion 5 of stock 4. The riser assembly may include riser 7 mounted to front portion 5, bow limbs 8a and 8b having proximal ends mounted to riser 7, cams 9a and 9b mounted to distal ends of bow limbs 8a and 8b, respectively, and bow string 10 engaging cams 9a and 9b. Alternatively, crossbow 2 may be a recurve crossbow including no cams.
Crossbow 2 may include receptacle member 12 in a side of stock 4. A second receptacle member 12 may be disposed in the other side of stock 4. Alternatively, crossbow stock 4 may only include a single receptacle member 12 in one side. Stock 4 may also include cover 14 near rear portion 6 of crossbow stock 4. Cover 14 may form a cheek piece of crossbow stock 4. Cover 14 may open by pivoting about pivot point 18.
FIGS. 2-4 illustrate receptacle member 12 separated from crossbow stock 4. Receptacle member 12 may include receptacle portion 20 and connection portion 22. Receptacle portion 20 may include two or more expanding members 24 separated by longitudinal gaps 26. Receptacle portion 20 may have a generally cylindrical shape with shoulder 28 at its distal end. The distal ends of expanding members 24 may form shoulder 28. In an alternate embodiment, receptacle portion 20 may have another shape (e.g., square, oval, triangular, hexagonal, etc.). The internal surfaces of expanding members 24 may form central cavity 30. Central cavity 30 may be dimensioned to receive a portion of a hook member of a crossbow cocking device. Expanding members 24 may expand to allow insertion of a portion of the hook member into central cavity 30. Connection portion 22 of receptacle member 12 may include key 32 having a flat surface 34 with bore 36 extending therethrough.
FIGS. 5 and 6 illustrate crossbow cocking device 40 including handle 42 and spool member 44. Handle receptacle 46 is also illustrated. Handle receptacle 46 is configured to attach to stock 4 and to receive handle 42 for storage on stock 4. Handle receptacle 46 may include shell members 48 and 50. Crossbow cocking device 40 may further include hook member 80, which is configured to engage receptacle member 12. Hook member 80 may include hook 82 and hook surface 84 for engaging a string of a crossbow being cocked. Hook 80 may also include rope spool surface 86 enclosing aperture 88. A rope of the crossbow cocking device may be disposed through aperture 88. The rope may slide along rope spool surface 86 as hook members 80 are drawn rearwardly along the crossbow in order to pull the crossbow string into a cocked position with hook 82.
Referring now to FIGS. 7 and 8, hook member 80 also includes fastener 90 disposed in recess 92 for connecting plug 94 to hook member 80. In one embodiment, fastener 90 and plug 94 each includes a threaded surface for threadedly engaging one another. Alternate fastener mechanisms known in the art may be employed without departing from the spirit of the invention. Plug 94 may include proximate end 96 configured for attachment to fastener 90, and distal end 98 configured to engage central cavity 30 of receptacle member 12. Proximate end 96 may be completely or partially disposed within recess 92 of hook member 80. Distal end 98 may have a shape that is reciprocal to the shape of central cavity 30 of receptacle member 12. In one embodiment, distal end 98 and central cavity 30 may each include a restricted portion extending to an expanded portion. The expanded portion of distal end 98 may be retained within central cavity 30 and the restricted portion of central cavity 30 may engage the restricted portion of distal end 98, thereby blocking distal end 98 from sliding out of central cavity 30. In this way, distal end 98 of plug 94 may engage central cavity 30 in order to attach hook 80 to receptacle member 12. With receptacle member 12 affixed to the side of crossbow stock 4, hook member 80 may be affixed to crossbow stock 4 by inserting distal end 98 of plug 94 into central cavity 30 of receptacle member 12.
FIGS. 9 and 10 illustrate crossbow 2 in a storage position. Hook members 80 are attached to receptacle members 12 in each side of crossbow stock 4. Each receptacle member 12 may be housed within recess 100 in each side surface of crossbow stock 4. Connection portion 22 and the cylindrical portion of receptacle portion 20 may be inserted into recess 100. In one embodiment, recess 100 extends entirely through the width of crossbow stock 4. In this embodiment, keys 32 of the two receptacle members 12 may overlap one another such that flat surface 34 of the first receptacle member 12 engages flat surface 34 of the second receptacle member 12. Fastener 102 may be secured through bore 36 of each receptacle member 12 to secure receptacle members 12 within recess 100. Fastener 102 may be a screw, a bolt, a pin, or any other suitable fastening device known in the art. Fastener 102 may further extend through bore 104 within crossbow stock 4. Shoulder 28 at distal end of each receptacle member 12 may engage the outer surface of the crossbow stock 4. Alternatively, a recess or bore of crossbow stock 4 may include a distal recess for housing shoulder 28 of receptacle member 12 such that shoulder 28 does not extend beyond the outer surface of the crossbow stock 4. In another alternate embodiment, receptacle member 12 may include no shoulder 28. In the storage position, handle 42 may secured to stock 4 with handle receptacle 46 for storage of handle 42 in the storage position.
With reference to FIGS. 11 and 12, crossbow stock 4 may include control 110 (also shown in FIG. 9) near rear portion 6. Actuation of control 110 may cause cover 14 to pivot from the closed position shown in FIG. 9 to the open position shown in FIG. 11. Opening cover 14 may expose spool bore 112 of crossbow stock 4. Spool bore 112 may be configured to receive spool member 44 of cocking device 40. In one embodiment, a spool bushing may be disposed within spool bore 112 to facilitate rotation of spool member 44 within spool bore 112. Spool member 44 may be positioned within spool bore 112 in the storage position and in the cocking position. Control 110 may be formed of a push button disposed through or within aperture 120 of butt plate 122. Butt plate 122 may be affixed to crossbow stock 4 with one or more fastening members 124. Button housing 126 may be disposed within crossbow stock 4 for receiving control 110. Spring 128 may be disposed between and bias shoulder 130 of button housing 126 against shoulder 132 of control 110. Distal end 134 of control 110 may engage first end 136 of catch member 138, which may also include pivot point 140 and second end 142. Second end 142 of catch member 138 may engage latch 144 of cover 14. Second end 142 of catch member 138 and latch 144 may each include a reciprocal shoulder for engaging the two components. Alternate engaging mechanisms known in the art may be employed for second end 142 and latch 144 without departing from the spirit of the invention.
Applying an inward force on control 110 compresses spring 128 and displaces first end 136 of catch member 138, thereby rotating catch member 138 around pivot point 140. The pivoting of catch member 138 causes second end 142 of catch member 138 to disengage from latch 144 of cover 14, which allows cover 14 to open. In this way, actuation of control 110 opens cover 14. Once the inward force is removed from control 110, spring 128 forces control 110 into its original position, which allows catch member 138 to return to its original position.
Referring now to FIG. 13, handle 42 of crossbow cocking device 40 may be connected to spool member 44 disposed through spool bore 112 with cover 14 in the open position. Rotation of handle 42 will rotate spool member 44, which may wind or unwind a rope or cable connected between spool member 44 and hook members 80. During use hook members 80 are not attached to receptacle members 12. In one embodiment, plug 94 may be positioned within and slide along a track of the crossbow stock during use. Alternatively, hook members 80 may be detached from crossbow stock 4 during use. With hook members 80 engaging bow string 10, rotation of handle 42 winds rope or cable of cocking device 40 to draw hook members 80 (one on either side of crossbow stock 4) and bow string 10 rearwardly along with the crossbow string in order to cock the crossbow.
Upon completion of using the crossbow cocking device (e.g., when the crossbow string is secured in the cocked position such as with a trigger catch), the handle may be disconnected from spool member 44 and cover 14 may be closed by engaging latch 144 of cover 14 with second end 142 of catch member 138. Hook members 80 may be stored on crossbow stock 4 by placing plug 94 in center cavity 30 of receptacle member 12. In one embodiment, a receptacle may be included on crossbow stock 4 for the handle of the crossbow cocking device. For example, handle receptacle 46 may be positioned near rear portion 6 of crossbow stock 4. Accordingly, crossbow stock 4 disclosed herein may be used to store components of a crossbow cocking device during transportation or use of the crossbow.
In one alternate embodiment, crossbow stock 4 may include receptacle member 12 without cover 14, control 110, or spool bore 112. In another alternate embodiment, crossbow stock 4 may include cover 14, control 110, and spool bore 112 without receptacle member 12. Each of these alternatives provides advantages over prior art crossbows by allowing a user to either store components of a crossbow cocking device when not in use or to conveniently cover spool bore 112 when not in use.
While preferred embodiments have been described, it is to be understood that the embodiments are illustrative only and that the scope of the invention is to be defined solely by the appended claims when accorded a full range of equivalents, many variations and modifications naturally occurring to those skilled in the art from a review hereof.
