Abstract
Abstract A net jointing structure is provided for separably jointing or coupling a pair of nets together. The structure has a pair of elongate net strips each having first and second longitudinal opposite edges and having a mesh size progressively smaller toward the second edge, the first edge being formed integrally or adapted for connection with one end of each of the nets. A sliding clasp fastener includes a pair of stringers each having on and along one longitudinal edge a row of interlocking elements and secured at the other longitudinal edge to the second edge of the elongate net strip, and a slider slidably mounted on the rows of interlocking elements for coupling and uncoupling the pair of stringers.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
120 words
A net jointing structure for releaseably joining a pair of nets together, comprising; a pair of elongate net strips each having first and second longitudinal opposite edges and having a mesh size progressively decreasing toward said second edge, the first edge of each net strip being connected to a corresponding end of each of said nets; and a sliding claps fastener including a pair of stringers each having on and along one longitudinal edge a row of interlocking elements and secured at the opposite longitudinal edge to the second edge of a corresponding net strip, and a slider slidably mounted on said rows of interlocking elements for coupling and uncoupling same to correspondingly connect and disconnect said pair of stringers.
Claim 2
Dependent Claim
120 words
A net jointing structure for releaseably joining a pair of nets together, comprising; a pair of elongate net strips each having first and second longitudinal opposite edges and having a mesh size progressively decreasing toward said second edge, the first edge of each net strip being connected to a corresponding end of each of said nets; and a sliding claps fastener including a pair of stringers each having on and along one longitudinal edge a row of interlocking elements and secured at the opposite longitudinal edge to the second edge of a corresponding net strip, and a slider slidably mounted on said rows of interlocking elements for coupling and uncoupling same to correspondingly connect and disconnect said pair of stringers.
Claim 3
Dependent Claim
44 words
A net jointing structure according to claim 1, wherein each of said net strips is comprised of a plurality of parallel sections extending longitudinally thereof, each section being smaller in mesh size than a neighboring inner one as measured progressively toward said second edge.
Claim 4
Dependent Claim
25 words
A net jointing structure according to claim 1, wherein said net section at said first edge is substantially equal in mesh size to said net.
Claim 5
Dependent Claim
102 words
A net jointing structure for separably releaseably joining a pair of nets together, comprising a pair of elongate net strips each having first and second longitudinal opposite edges and having a mesh size progressively decreasing toward said second edge, the first edge of each net strip being connected to a corresponding end of each of said nets; a pair of rows of fastener elements each row secured to the second edge of a corresponding net strip; and a slider slidably mounted on said rows of fastener elements for coupling and uncoupling same to correspondingly connect and disconnect said rows of fastener elements.
Claim 6
Dependent Claim
102 words
A net jointing structure for separably releaseably joining a pair of nets together, comprising a pair of elongate net strips each having first and second longitudinal opposite edges and having a mesh size progressively decreasing toward said second edge, the first edge of each net strip being connected to a corresponding end of each of said nets; a pair of rows of fastener elements each row secured to the second edge of a corresponding net strip; and a slider slidably mounted on said rows of fastener elements for coupling and uncoupling same to correspondingly connect and disconnect said rows of fastener elements.
Claim 7
Dependent Claim
44 words
A net jointing structure according to claim 4, wherein each of said net strips is comprised of a plurality of parallel sections extending longitudinally thereof, each section being smaller in mesh size than a neighboring inner one as measured progressively toward said second edge.
Claim 8
Dependent Claim
25 words
A net jointing structure according to claim 4, wherein said net section at said first edge is substantially equal in mesh size to said net.
Claim 9
Dependent Claim
121 words
A net jointing structure for releaseably joining a pair of nets together, comprising: a pair of elongate net strips each having first and second longitudinal opposite edges and having a mesh size progressively decreasing toward said second edge, the first edge of each net strip being formed integrally with a corresponding end of each of said nets; and a sliding clasp fastener including a pair of stringers each having on and along one longitudinal edge a row of interlocking elements and secured at the opposite longitudinal edge to the second edge of a corresponding net strip, and a slider slidably mounted on said rows of interlocking elements for coupling and uncoupling same to correspondingly connect and disconnect said pair of stringers.
Claim 10
Dependent Claim
121 words
A net jointing structure for releaseably joining a pair of nets together, comprising: a pair of elongate net strips each having first and second longitudinal opposite edges and having a mesh size progressively decreasing toward said second edge, the first edge of each net strip being formed integrally with a corresponding end of each of said nets; and a sliding clasp fastener including a pair of stringers each having on and along one longitudinal edge a row of interlocking elements and secured at the opposite longitudinal edge to the second edge of a corresponding net strip, and a slider slidably mounted on said rows of interlocking elements for coupling and uncoupling same to correspondingly connect and disconnect said pair of stringers.
Claim 11
Dependent Claim
44 words
A net jointing structure according to claim 7, wherein each of said net strips is comprised of a plurality of parallel sections extending longitudinally thereof, each section being smaller in mesh size than a neighboring inner one as measured progressively toward said second edge.
