    摘要: A device for isolating vibration and motion which may be used to dampen or isolate vibrations and motion from heating, ventilation, air conditioning, mechanical and/or electro-mechanical equipment to reduce or eliminate the deleterious effects of vibration, movement and excessive noise created by the equipment. The device includes one or more pairs of vertical limiters, one or more springs, a pair of and at least two flanges. The frame members are each in a fixed relation to at least one vertical limiter which has a slot therein wherein the vertical limiters each have a respective engagement portion/cross beam which is partially passed through the opposing vertical limiters slot such that the vertical limiter pair allows the flanges each to move in toward or away from each other, but wherein the vertical limiters function as to prevent twisting or sliding of the flanges with respect to each other. The spring assemblies and vertical limiters receive and diminish the undesirable phenomena created by the equipment or other sources of vibrations or motion.

    摘要: An inter-element joint structure including: a first member provided with a hole or a trench; a second member provided with a through-hole; a bushing member fitted to the through-hole formed in the second member and fixed to the second member while the bushing member comes into contact with a surface of the first member; a fastening member including a bolt provided with a shank penetrating at least the bushing member and the hole or the trench of the first member to fasten the bushing member and the first member; and a washer that is interposed between a head of the bolt and the bushing member and has a diameter larger than that of the bushing member. The bushing member has a thickness larger than that of the second member, and the through-hole of the second member has a circumferential edge loosely fitted between the washer and the first member.
