HOLLOW RESIN PRODUCT

Japanese Patent JP3505946

B2

PROBLEM TO BE SOLVED: To obtain sufficient connecting strength in the connecting part of resin by forming a passage for packing a resin for connection into the interconnecting parts of the resin parts and providing a reinforcing mean for preventing the passage from becoming deformed resisting the pressure of a packed resin at the time of filling the passage with the resin for connection.
SOLUTION: A stool with a warming device, for example, as a hollow resin product consists of a stool seat main body 1 of resin with a heating element 3 arranged on the inner face interconnected to a stool seat rear plate 2 of resin opposite to the stool at a connecting part and a space part 4 for heat insulation formed internally. In addition, L-cross section parts 6, 7 are provided on the outer peripheral edge of the internal lower end of the stool main body 1 and on the outer peripheral edge of the internal upper part of the stoop seat rear plate 2. Further, these L-cross section parts 6, 7 are arranged opposite the each other so that a passage 5 for enabling a resin for connection to be packed into a space between the parts 6, 7 is formed. When the resin for connection is packed into the passage 5, the passage 5 becomes deformed by the bending of part of the L-cross section part 6 of the stool seat main body 1 due to a resin pressure. To prevent this phenomenon from occurring, a protrusion 9 is formed on the inside of the L-cross section part 7 provided on the stool seat rear plate 2.
