Abstract
Abstract A shield or protecting device which is attached to the split limb end section of a compound bow, a crossbow or any other archery device using a cam or eccentric wheel inserted into the split limb end section of the device. The shield is made in such a manner as to protect the cam or eccentric wheel when in a resting position, during the draw or in full extension of a compound bow, crossbow or any other archery device using a cam or eccentric wheel inserted into the split limb end section of the device. Space is provided in the cavity of the shield to protect the cam or eccentric wheel as it extends out over the split limb section of the compound bow, crossbow or other archery devices as described above. The shield is used to protect the cam or eccentric wheel and cable from any damage due to moisture, dirt, snow, twigs, rocks and any other foreign material which may cause damage to the cam or eccentric wheel and the cable when place on the ground. The shield is a quieting device, made in such a manner as to quiet the cam or eccentric wheel after the release of the arrow. The shield is also used to `shield` visual movement of the cams or eccentric wheels from the view of the game as the compound bow, crossbow or other archery devece described above is being drawn.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
165 words
A shield to be attached to a split limb section of a compound bow, crossbow, or any other archery device using a cam or eccentric wheel inserted into the split limb section, the shield comprising: a housing defining a cavity comprising: a pair of substantially parallel and coextensive side members each having a proximal end, a distal end, a front edge, and a back edge, the proximal ends sized and shaped to receive the split limbs of the bow essentially along the longitudinal axis of the bow limb, and distal ends extending beyond the maximum extension of the eccentric wheel assembly of the bow, and a wall member joining the side members along the back edges of the side members so as to define the cavity between the proximal and distal ends of the sidemembers, the configuration of the cavity such that it spans the eccentric wheel while permitting the operation of the bow cable(s); and means for rigidly attaching the housing to the bow.
Claim 2
Dependent Claim
165 words
A shield to be attached to a split limb section of a compound bow, crossbow, or any other archery device using a cam or eccentric wheel inserted into the split limb section, the shield comprising: a housing defining a cavity comprising: a pair of substantially parallel and coextensive side members each having a proximal end, a distal end, a front edge, and a back edge, the proximal ends sized and shaped to receive the split limbs of the bow essentially along the longitudinal axis of the bow limb, and distal ends extending beyond the maximum extension of the eccentric wheel assembly of the bow, and a wall member joining the side members along the back edges of the side members so as to define the cavity between the proximal and distal ends of the sidemembers, the configuration of the cavity such that it spans the eccentric wheel while permitting the operation of the bow cable(s); and means for rigidly attaching the housing to the bow.
Claim 3
Dependent Claim
43 words
A shield to be attached to a split limb section of a compound bow as defined in claim 1 wherein the side members have limb rests intregral to the side members within the cavity upon which the split limbs of the bow rest.
Claim 4
Dependent Claim
46 words
A shield to be attached to a split limb section of a compound bow as defined in claim 2 wherein the integral limb rest is formed by varying the planar configuration of the side member to create a seating surface against which a limb may rest.
Claim 5
Dependent Claim
31 words
A shield to be attached to a split limb section of a compound bow as defined in claim 1 wherein the side members in plan view are substantially semi-circular in shape.
Claim 6
Dependent Claim
36 words
A shield to be attached to a split limb section of a compound bow as defined in claim 1 wherein at least a portion of the cavity is lined with a shock and/or sound absorbing material.
Claim 7
Dependent Claim
56 words
A shield to be attached to a split limb section of a compound bow as defined in claim 1 wherein the wall member extends along the back edges of the sidemembers from the distal end of the side member toward the proximal end of the sidemembers terminating a distance from the proximal end of the sidemembers.
Claim 8
Dependent Claim
36 words
A shield to be attached to a split limb section of a compound bow as defined in claim 6 wherein the side members and wall member span only a distal portion of the eccentric wheel assembly.
Claim 9
Dependent Claim
123 words
A shield to be attached to a split limb section of a compound bow, crossbow, or any other archery device using a cam or eccentric wheel inserted into the split limb section, the shield comprising: two, substantially coextensive side members having a substantially semicircular shape, and having a proximal and a distal end, a wall member joining the side members along the arcuate sides of the semicircular side members between the proximal and distal ends to define a housing with a cavity therein, the proximal ends of the side members configured to receive the split limbs of the bow essentially along the longitudinal axis of the bow limb, and means for attaching the proximal ends of the side members to the bow limb.
Claim 10
Dependent Claim
123 words
A shield to be attached to a split limb section of a compound bow, crossbow, or any other archery device using a cam or eccentric wheel inserted into the split limb section, the shield comprising: two, substantially coextensive side members having a substantially semicircular shape, and having a proximal and a distal end, a wall member joining the side members along the arcuate sides of the semicircular side members between the proximal and distal ends to define a housing with a cavity therein, the proximal ends of the side members configured to receive the split limbs of the bow essentially along the longitudinal axis of the bow limb, and means for attaching the proximal ends of the side members to the bow limb.
Claim 11
Dependent Claim
43 words
A shield to be attached to a split limb section of a compound bow as defined in claim 8 wherein the side members have limb rests intregral to the side members within the cavity upon which the split limbs of the bow rest.
Claim 12
Dependent Claim
46 words
A shield to be attached to a split limb section of a compound bow as defined in claim 9 wherein the integral limb rest is formed by varying the planar configuration of the side member to create a seating surface against which a limb may rest.
Claim 13
Dependent Claim
36 words
A shield to be attached to a split limb section of a compound bow as defined in claim 8 wherein at least a portion of the cavity is lined with a shock and/or sound absorbing material.
Claim 14
Dependent Claim
52 words
A shield to be attached to a split limb section of a compound bow as defined in claim 8 wherein the wall member extends along the arcuate sides of the sidemembers from the distal end toward the proximal end of the sidemembers terminating a distance from the proximal end of the sidemembers.
Claim 15
Dependent Claim
36 words
A shield to be attached to a split limb section of a compound bow as defined in claim 12 wherein the side members and wall member span only a distal portion of the eccentric wheel assembly.
