User device and case
A user device that can be touched by a user includes a heat source that can generate heat; a case body covering the heat source; and a polymer-containing heat storage body attached to the case body.
1. A user device configured to be touched by a user, the user device comprising:
a heat source configured to generate heat;
a case body covering the heat source; and
a polymer-containing heat storage body attached to the case body,
wherein the polymer-containing heat storage body is a cured product of a curable composition containing:
a curing agent and
a polymer having heat storage property and including a structural unit represented by the following Formula (1-1) and a structural unit represented by the following Formula (1-2):
wherein R 1 and R 3 each independently represent a hydrogen atom or a methyl group; R 2 represents an alkyl group having 12 to 30 carbon atoms or a monovalent group having a polyoxyalkylene chain; and R 4 represents a hydrogen atom or a monovalent organic group having a reactive group.
2. The user device according to claim 1 , wherein the polymer-containing heat storage body is attached to a surface adjacent to the heat source of the case body.
3. The user device according to claim 1 , wherein the user device is a portable terminal carried by the user.
4. The user device according to claim 1 , wherein the user device is a wearable terminal to be worn on a body of the user.
5. The user device according to claim 4 , wherein the polymer-containing heat storage body is attached to a portion of the case body facing the body of the user and to a surface adjacent to the heat source of the case body.
6. The user device according to claim 1 ,
wherein the user device further comprises a heat conductor connected to the heat source, and
wherein the polymer-containing heat storage body is in contact with the heat conductor.
7. A case of a user device, the case comprising:
a case body covering at least a portion of the user device; and
a polymer-containing heat storage body attached to the case body,
wherein the case is configured to be fitted to the user device which includes a heat source configured to generate heat, and which configured to be touched by a user, and
wherein the polymer-containing heat storage body is a cured product of a curable composition containing:
a curing agent and
a polymer having heat storage property and including a structural unit represented by the following Formula (1-1) and a structural unit represented by the following Formula (1-2):
wherein R 1 and R 3 each independently represent a hydrogen atom or a methyl group; R 2 represents an alkyl group having 12 to 30 carbon atoms or a monovalent group having a polyoxyalkylene chain; and R 4 represents a hydrogen atom or a monovalent organic group having a reactive group.
8. The user device according to claim 1 , wherein a first surface of the polymer-containing heat storage body abuts the heat source, and a second surface of the polymer-containing heat storage body opposite to the first surface abuts the case body.
9. The user device according to claim 6 , wherein a first surface of the polymer-containing heat storage body abuts the heat conductor, and a second surface of the polymer-containing heat storage body opposite to the first surface abuts the case body.
10. The case according to claim 7 , wherein a first surface of the polymer-containing heat storage body faces the user device, and a second surface of the polymer-containing heat storage body opposite to the first surface abuts the case body.
