发明名称 Torsion coil spring
摘要 A spring suitable for use in bedding construction, including mattresses, mattress-bases and the like which is able to achieve a variety of spring heights and resiliences using the same thickness of wire. The spring includes a first leg (2), a first upper foot (3), a first lower foot (4), a second leg (2), a second upper foot (3), a second lower foot (4), at least one coil spring (5) and linking means (6). The spring's first leg links the first upper foot to the first lower foot and includes at least one coil spring (5) at some point along its length. The spring's second leg links the second upper foot to the second lower foot and includes at least one coil (5) spring at some point along its length. The linking means links the first upper foot to the second upper foot in such a way that the first leg, first upper foot, and first lower foot are oriented at approximately 180 degrees relative to the second leg, second upper foot, and second lower foot.
