An adhesive fastening element (802) for holding a workpiece (808), the adhesive fastening element (802) comprising: an outer member (804); and a consumable inner member (806) disposed inside the outer member (804) and releasably movable relative to the outer member (804) along a longitudinal axis of the adhesive fastening element (802); wherein the consumable inner member (806) comprises a bonding surface which, in use, is bonded by an adhesive (810) to the workpiece (808) and is removed and replaced to detach the workpiece (808) from the adhesive fastening element (802).
摘要:
An adhesive fastening element includes a first member and a second member adjacent to the first member and movable relative to the first member along a longitudinal axis of the adhesive fastening element, wherein a bond is formed by an adhesive between the workpiece and the first and second members of the adhesive fastening element. A method for de- bonding a workpiece from an adhesive fastening element includes moving the second member away from the workpiece and breaks the bond between the second member and the workpiece and moving the first and second members such that the second member moves towards the workpiece and applies a force to the workpiece so as to break the bond between the first member and the workpiece, and lo de-bond the workpiece from the adhesive fastening element.

In accordance with principles described herein, portable heated seats, and methods and systems for using the same, are provided that overcome some (or all) of the problems commonly associated with existing seats. These portable heated seats are easily transportable, and are preferably provided with cushion material to compensate for various seating conditions that may otherwise be faced by a user. One or more heating elements, preferably made of flexible graphite felt, are also provided in each portable heated seat. The heat settings of the one or more heating elements are controlled by one or more on/off switches, open loop temperature regulators, pressure push switches, sensor switches, and/or fuse circuits. A backrest (similarly heated or not heated) may also be used in association with the portable heated seat. Various alternative embodiments are also disclosed.
