Abstract
The present invention provides a device forming a controlled-release mechanism, the device comprising: two structural elements suitable for relative movement; and locking means suitable initially for preventing relative movement between the two structural elements, and in which the locking means comprises in combination: at least one set of complementary shape means of helical configuration associated with respective ones of the two structural elements; and a low-melting point material disposed at least in part at an interface between two parts connected respectively to the two structural elements to prevent the locking means being released, and consequently to prevent the structural elements being released, prior to said material melting.

A device forming a controlled-release mechanism, the device comprising:
- two structural elements suitable for relative movement;
- and
- locking means suitable initially for preventing relative movement between the two structural elements, and in which the locking means comprises in combination:
- at least one set of complementary shape means of helical configuration associated with respective ones of the two structural elements;
- and
- a low-melting point material disposed at least in part at an interface between two parts connected respectively to the two structural elements to prevent the locking means being released, and consequently to prevent the structural elements being released, prior to said material melting, said low-melting point material melting within a temperature range of about 95° C. to 300° C.
