Embodiment Construction

[0073] Embodiments of the invention are discussed below. Figures 1 to 5 A first embodiment of a screw attachment, a fastening assembly with the screw attachment and a method for releasing the fastening assembly according to the invention is shown.

[0074] figure 1 A portion of an LCD TV 20 is shown to discuss an example of a fastening assembly. The fastening assembly uses a washer (screw attachment) 10 made of shape memory alloy, allowing an easy disassembly process. The LCD TV 20 has a plastic frame 21 for accommodating a box body, a liquid crystal panel body 23, lamps (not shown), thin plates (not shown) and the like. The frame 21 includes a panel frame 25 and a panel cover (fixed object) 22 , and the panel cover 22 covers an opening of the liquid crystal panel body 23 . The liquid crystal panel body 23 has a pair of front and rear glass plates, a liquid crystal thin plate, a deflection plate, a reflector plate, an electronic circuit unit, and the like. The liquid cry...

Abstract

A spacer (10, 10' , 10'') disposed around a fastening piece (17) secured to a main fastening body (25a) , the spacer sandwiched between ahead (17b) of the fastening piece and a securing object (22) so that the spacer bears a securing force of the fastening piece to press the securing object. spacer includes a pair of arms (12, 13) made of a shape restoring material. Each arm has a fore end, and the fore ends are joined to each other with an adhesive material that is softened when heated. The arms expands radially such that the screw attachment is released from the head of the fastening piece when heat or force is applied to the arms.

Description

technical field [0001] The present invention relates to a screw attachment, a fastening assembly with the screw attachment and a method of releasing the fastening assembly, which are effectively applied to a device or machine capable of recycling, such as air conditioners, refrigerators, television sets, batteries group and portable charger. Background technique [0002] Recycling of electrical appliances such as air conditioners, washing machines, and refrigerators to recycle natural resources has been recognized to be positive from an environmental standpoint. However, removing fastening screws on electrical appliances is time consuming. Thus, a sufficiently efficient recovery method has not yet been developed. [0003] Figures 16 to 18 show examples of fastener and screw attachments made from shape memory alloys. The first prior art disclosed in Japanese Utility Model No. H-2-36616 (especially pages 4 to 6 and Figure 5 ) shows a means for preventing the bolt 60 from l...
