Inflatable paddle board and thermal bonding method thereof
An inflatable paddle board includes a main body including two body layers, and a peripheral enclosing strip which is integrated with the two body layers by thermal bonding to form an inflation chamber between the two body layers and the peripheral enclosing strip, the peripheral enclosing strip comprises one or more strip parts which are wrapped around edges of the two body layers.
1 . An inflatable paddle board, comprising:
a main body comprising two body layers; and
a peripheral enclosing strip which is integrated with the two body layers by thermal bonding to form an inflation chamber between the two body layers and the peripheral enclosing strip, wherein the peripheral enclosing strip comprises a plurality of strip parts which are connected with each other, wherein each strip part of the peripheral enclosing strip comprises two surface layers and a mesh layer between the two surface layers, each mesh layer comprises a plurality of first yarns and a plurality of second yarns which are perpendicular to each other:
wherein the plurality of first yarns and the plurality of second yarns are respectively inclined with respect to a length direction of the peripheral enclosing strip.
2 . The inflatable paddle board according to claim 1 , wherein an inclined angle between the first yarns and the length direction of the peripheral enclosing strip is 30°-60°.
3 . An inflatable paddle board, comprising:
a main body comprising two body layers; and
a peripheral enclosing strip which is integrated with the two body layers by thermal bonding to form an inflation chamber between the two body layers and the peripheral enclosing strip, wherein the peripheral enclosing strip comprises a plurality of strip parts which are connected with each other, wherein the plurality of strip parts are integrated with each other without requiring a glue to bond two adjacent strip parts:
wherein each strip part of the peripheral enclosing strip comprises two surface layers and a mesh layer between the two surface layers, each mesh layer comprises a plurality of first yarns and a plurality of second yarns which are perpendicular to each other, wherein the plurality of first yarns and the plurality of second yarns are inclined with respect to a length direction of the peripheral enclosing strip.
4 . The inflatable paddle board according to claim 3 , wherein an inclined angle between the first yarns and the length direction of the peripheral enclosing strip is 45°.
5 . The inflatable paddle board according to claim 3 , further comprising a decoration strip which is attached on the peripheral enclosing strip, the decoration strip comprises a plurality of strip parts each comprising a plurality of first yarns and a plurality of second yarns which are perpendicular to each other, wherein the first yarns and the second yarns in one or more of the plurality of strip parts are inclined yarns with respect to a length direction of the peripheral enclosing strip.
6 . The inflatable paddle board according to claim 3 , wherein the main body comprises a plurality of connecting threads connected between the two body layers, a width of a portion of the peripheral enclosing strip between edges of the two body layers is smaller than a height of the connecting threads between the two body layers, wherein the connecting threads between the edges of the two body layers are removed or cut off in the middle.
7 . The inflatable paddle board according to claim 3 , wherein the first yarns of the two strip parts on two sides of each of the head portion and the tail portion are arranged in mirrored sloping lines.
8 . The inflatable paddle board according to claim 3 , wherein the two body layers are PVC or TPU drop stitch fabrics, wherein a plurality of connecting threads are connected between the two body layers.
9 . The inflatable paddle board according to claim 8 , wherein each surface layer of each strip part of the peripheral enclosing strip is made of PVC or TPU, the mesh layer is made of a fiber material selected from the group consisting of polyester terylene fiber, nylon and aramid fiber.
10 . An inflatable paddle board, comprising:
a main body comprising two body layers; and
a peripheral enclosing strip which is integrated with the two body layers by thermal bonding to form an inflation chamber between the two body layers and the peripheral enclosing strip, wherein the peripheral enclosing strip comprises a middle strip, an upper strip integrated on an upper edge of the middle strip and a lower strip integrated on a lower edge of the middle strip;
wherein each of the middle strip, the upper strip and the lower strip comprises two surface layers and a mesh layer between the two surface layers, wherein each mesh layer comprises a plurality of first yarns and a plurality of second yarns which are perpendicular to each other, the first yarns and the second yarns in each of the upper strip and the lower strip are inclined yarns with respect to a length direction of the peripheral enclosing strip.
