Quick release coupling/pulley assembly for improved weaving device

A weaving device having a frame, a resilient member mounted on the frame, an eyelet mounted to the resilient member and movable with respect to the frame, and a first cord mounted on the eyelet, the weaving device comprising;

• a module releasably borne by the frame and operable to selectively transmit a motive force to the eyelet;
• a second cord mounted on the module;
• and
• a coupling having a first and second member releasably fastened together, and wherein the first member is operably engaged by the first cord, and the second member is operably engaged by the second cord, and wherein the coupling coacts with the first and second cords to transmit the motive force from the module to the eyelet to effect movement of the eyelet relative to the frame, and wherein the detachment of the first and second members facilitates removal and replacement of the module.

A weaving device having a frame, a resilient member mounted on the frame, an eyelet mounted on the resilient member and movable with respect to the frame, and a first cord having a first end which is fixedly mounted on the frame and a second end which is mounted on the eyelet and movable therewith, the weaving device comprising;

• a module releasably borne by the frame;
• a griff bar mounted on the module and reciprocally movable along a path of travel in relation thereto;
• a latch pivotally borne by the module;
• a solenoid borne by the module and disposed in coactive relation to the latch, and operable to influence the positional disposition of the latch by the production of a magnetic field when energized;
• a hook movably borne by the module and selectively engageable by the latch and griff bar, and which coacts with same so as to be selectively movable along the path of travel of the griff bar;
• a second cord having a first and second ends which are connected to the module, and mount the hook for movement responsive to movement of the griff bar;
• a coupling having a first and second member which are releasably fastened together, and wherein the first member has a sheave rotatably mounted thereon which is operably engaged with the first cord between the first and second ends thereof, and which coacts therewith to affect movement of the eyelet, and wherein the second member has a sheave rotatably mounted thereon and which is operably engaged with the second cord between the first and second ends thereof, and wherein the first member has a male fastening portion, and the second member has a complimentary female fastening portion which receives the male fastening portion in releasable interlocking relation therewith;
• and
• a tool selectively engageable with the coupling to detach the first and second members.

A coupling and associated tool for use with a weaving device which has a frame, an eyelet movably mounted on the frame, and a motor which selectively produces a motive force which acts upon the eyelet, the coupling and related tool comprising:

• a first member which is mounted in force transmitting relation relative to the eyelet, the first member having a main body with opposite first and second ends, and wherein the main body defines an internal cavity, and wherein an aperture is formed in the first end of the main body and communicates with the cavity, a sheave rotatably mounted in the cavity, and a pair of resiliently deflectable arms disposed on the second end of the main body, and wherein each of the deflectable arms has a proximal end which is made integral with the second end of the main body, and an opposite distal end, and wherein the respective deflectable arms move along a path of travel between a locked position and an unlocked position, and wherein a space is defined between the respective deflectable arms, and the second end of the main body;
• second member releasably coupled to the first member, and wherein the second member has a main body with opposite first and second ends, and wherein the second end is disposed in force receiving relation relative to the motive force, and wherein the main body defines a tool receiving aperture formed in the main body and is located intermediate of the first and second ends of the main body, and wherein a sheave is rotatably mounted adjacent the second end of the main body, and wherein a locking member is mounted on the second member, and wherein when the first and second members are releasably coupled together, the respective deflectable arms are received in the second member and are disposed in releasable interlocking relation relative to the locking member, and partially occlude the tool receiving aperture;
• and
• a tool for mating receipt in the tool receiving aperture, the tool facilitating the engagement and disengagement of the first and second members, and wherein the tool, when received in the tool receiving aperture, disengages the respective deflectable arms from the locking member.
