1. A device comprising:
- a first handle connected to a first end of a flexible member;
a second handle slidably engaged with the flexible member, wherein the first and second handles are adapted to be grasped by a user;
a housing, integral with the second handle, and comprising a retraction device operatively connected to a second end of the flexible member, wherein the retraction device is adapted to retract at least a portion of the flexible member into an interior portion defined by the housing;
a first hook member slidably coupled to the flexible member, wherein the first hook member comprises a first attachment assembly and a first coupling assembly;
a second hook member slidably coupled to the flexible member, wherein the second hook member comprises a second attachment assembly and a second coupling assembly;
wherein the first and second hook members are positioned between the first and second handles;
wherein the first and second attachment assemblies are adapted to receive at least a portion of an associated crossbow bowstring;
wherein the first and second coupling assemblies are adapted to at least partially enable the movement of the first and second hook members, respectively, along at least a portion of the flexible member;
wherein the retraction device comprises;
a shaft member rotatably coupled to the housing;
a pair of end plates connected to ends of the shaft member, wherein the end plates rotate in conjunction with the shaft member and retain at least a portion of the flexible member retracted into the housing; and
,a biasing member operatively connected to the shaft member to urge the shaft member to rotate in a first direction, wherein rotation of the shaft member in the first direction causes the flexible member to wind around a circumference of the shaft member between the pair of end plates.

9. A crossbow cocking apparatus comprising:
-
a first handle connected to a first end of a flexible member; a second handle operatively connected to a second end of the flexible member, wherein the first and second handles are adapted to be grasped by a user, the second handle comprising; a refraction device connected to the second end of the flexible member, wherein the retraction device is configured to retract at least a portion of the flexible member into an interior portion of the second handle, wherein the retraction device comprises, a shaft member rotatably coupled to the interior portion of the second handle, first and second end plates operably coupled to first and second ends of the shaft member, respectively, wherein the first and second end plates are configured to rotate in conjunction with the shaft member and retain at least a portion of the flexible member retracted into the interior portion of the second handle, and, a biasing member operatively connected to the shaft member and configured to urge the shaft member to rotate in a first direction, wherein rotation of the shaft member in the first direction causes the flexible member to wind around a circumference of the shaft member between the first and second end plates, a first hook member slidably coupled to the flexible member, and configured to selectively engage a first portion of an associated crossbow bowstring; a second hook member slidably coupled to the flexible member, and configured to selectively engage a second portion of the associated crossbow bowstring; wherein the first handle and the second handle respectively comprise a coupling device configured to selectively engage the said first handle with the second handle, the coupling device comprising, a first magnet fixedly engaged with the first handle, and, a second magnet fixedly engaged with the second handle.

10. A method for cocking a crossbow comprising the steps of:
-
selectively engaging a first hook member of a crossbow cocking device with a first portion of a bowstring of a crossbow, wherein the first hook member is slidably engaged with a flexible member of the crossbow cocking device; extending the flexible member from a housing operably engaged with a second handle of the crossbow cocking device, wherein the housing comprises a retraction device connected to a second end of the flexible member, wherein the retracting device is configured to; allow the flexible member to be extended from the housing during a crossbow cocking operation; and
,retract at least a portion of the flexible member into the housing outside of the crossbow cocking operation; selectively engaging a second hook member of the crossbow cocking device with a second portion of the bowstring of the crossbow, wherein the second hook member is slidably engaged with the flexible member of the crossbow cocking device; selectively engaging a portion of the flexible member with a portion of the crossbow between the first hook member and the second hook member; and cocking the bowstring on the crossbow comprising; grasping a first handle connected to a first end of the flexible member; grasping the second handle; and exerting a rearward force on the first and second handles at least until the bowstring is disposed in a cocked position with regards to the crossbow; wherein the refraction device is configured to retract at least a portion of the flexible member into the housing by urging a shaft member to rotate in a first direction, wherein rotation of the shaft member in the first direction at least partially causes the retraction of the flexible member and the shaft member is rotatably coupled to the housing and a biasing member is operatively connected to the shaft member to urge the shaft member to rotate in the first direction and the rotation of the shaft member in the first direction causes the flexible member to be wound around the circumference of the shaft member. - View Dependent Claims (11, 12, 13, 14, 15)
