Thermal insulating profile

Abstract

A thermal insulating profile includes: a first profile portion made of metal; a second profile portion made of metal; a thermal insulating material made of a foaming resin material, the thermal insulating material being configured to couple the first profile portion and the second profile portion to each other; an injection port formed, along a longitudinal direction of the thermal insulating profile, between the first profile portion and the second profile portion; and a closing member disposed at the injection port to close the injection port.

What is claimed is: 
     
         1 . A thermal insulating profile, comprising:
 a first profile portion made of metal;   a second profile portion made of metal;   a thermal insulating material made of a foaming resin material, the thermal insulating material being configured to couple the first profile portion and the second profile portion to each other;   an injection port formed, along a longitudinal direction of the thermal insulating profile, between the first profile portion and the second profile portion; and   a closing member disposed at the injection port to close the injection port.   
     
     
         2 . The thermal insulating profile according to  claim 1 , wherein the thermal insulating material is formed of a foaming resin material having an expansion ratio of 3 to 5. 
     
     
         3 . The thermal insulating profile according to  claim 1 , wherein
 the first profile portion and the second profile portion each include a portion to hooked, and   the closing member includes a closing body portion disposed at the injection port and a hooking portion configured to be hooked to portions to be hooked of the first profile portion and the second profile portion.   
     
     
         4 . The thermal insulating profile according to  claim 3 , wherein
 the hooking portion includes engaging protrusions that are elastically deformable, and   the engaging protrusions include distal end portions provided with claw portions to be engaged with the portions to be hooked of the first profile portion and the second profile portion.   
     
     
         5 . The thermal insulating profile according to  claim 4 , wherein
 the hooking portion has a pair of the engaging protrusions,   a protruding length dimension of the pair of the engaging protrusions between the closing body portion and the claw portions is larger than a thickness dimension of the portions to be hooked of the first profile portion and the second profile portion,   a dimension from a surface of one of the pair of the engaging protrusions that faces the portion to be hooked to a surface of another of the pair of the engaging protrusions that faces the portion to be hooked is smaller than a width dimension of the injection port, and   a dimension between distal ends of the claw portions along a width direction of the injection port is larger than the width dimension of the injection port.   
     
     
         6 . The thermal insulating profile according to  claim 4 , wherein the closing member includes a backing protrusion for the engaging protrusions, the backing protrusion protruding from the closing body portion. 
     
     
         7 . The thermal insulating profile according to  claim 6 , wherein an air escaping groove is formed between the engaging protrusions and the closing body portion. 
     
     
         8 . The thermal insulating profile according to  claim 4 , wherein
 a part of the engaging protrusions that abuts on the portions to be hooked of the first profile portion and the second profile portion is formed from a soft resin material, and   the closing member is formed from a hard resin material except for the part formed from the soft resin material.   
     
     
         9 . The thermal insulating profile according to  claim 3 , wherein
 a part of the closing member that abuts on a portion to be hooked of one of the first profile portion and the second profile portion is formed from a soft resin material, and   a part of the closing member that abuts on a portion to be hooked of another of the first profile portion and the second profile portion is formed from a hard resin material.   
     
     
         10 . The thermal insulating profile according to  claim 1 , wherein open cells that are continuous from an inner surface on a thermal insulating material side to an outer surface on an exterior side are formed in the closing member. 
     
     
         11 . The thermal insulating profile according to  claim 1 , wherein
 a cavity is formed between the first profile portion and the second profile portion,   the closing member includes an abutment piece portion configured to abut on the first profile portion or the second profile portion in the cavity, and   the abutment piece portion is configured to partition the cavity into a thermal insulating space in which the thermal insulating material is disposed and a hollow space.
