  • Patent number: 8493225
    Abstract: An impact detector includes a weight having a circular periphery, a case in which the weight is contained, an interior of which defines a transition path that connects an initial position and an impact detection position, and a restriction portion projecting from the interior of the case into the transition path. The weight moves through the transition path to the impact detection position with a circumferential surface of the weight in contact with the interior of the case when the case receives an impact in a predetermined direction, and the restriction portion restricts movement of the weight toward the impact detection position when the case receives impact in a direction other than the predetermined direction.

  • Patent number: 8307775
    Abstract: An impact detector includes a circular weight, a case containing the weight, in which a transition path for the weight is formed, a planar elastic member extending in the case with a first end oriented in a direction in which the weight move upon an impact in a first direction, a fixing member fixing the planar member to the case. The planar elastic member includes a folded portion disposed on a second end of the planar elastic member, and a first arm and a second arm both extending from the folded portion. An end portion of the first arm holds the weight at an initial position, and the first arm deforms to release the weight upon the impact in the first direction. The fixing member includes a sandwiching portion sandwiching the folded portion and a contact portion in contact with both the first arm and the second arm.

  • Patent number: 8234993
    Abstract: An impact detector includes a case, an impact indicator disposed on a front side of the case, to indicate an impact history of the impact detector, a first weight that moves inside the case to a side to which the case falls, causing the impact indicator to indicate the impact history by moving through at least one of a first transition path and a second transition path, a first guide member to guide the first weight to a first impact detection position along the first transition path when the case falls in a first direction, and a second guide member to guide the first weight to the second impact detection position along the second transition path when the case falls in a second direction. The first transition path at least partly overlaps with the second transition path on a projection plane on the front side of the case.

  • Patent number: 8157093
    Abstract: A packing unit includes a pallet, a structural base, and a fixing device. The pallet mounts an article thereon. The structural base has a fixed portion and is detachably attached to the article. The fixing device fixes the article to the pallet and includes an article fixing member slidably supported by the pallet. The article fixing member is movable between a fix position at which the article fixing member is engaged with the fixed portion of the structural base of the article to fix the article to the pallet and a release position at which the engagement of the article fixing member and the fixed portion is released.

  • Patent number: 8074489
    Abstract: An impact detection sensor is attached to a packaging container. When the packaging container is subjected to impacts downward in a vertical direction twice, i.e., a bottom surface of the packaging container is subjected to impacts twice, a weight moves downward in the vertical direction by the application of the first impact, and is seen through a weight indicator unit located on the bottom of an impact detection sensor. At the time of the application of the second impact, the weight moved downward in the vertical direction is prevented from moving back to. an initial position by a pressing portion, and seen through the same bottom weight indicator unit.

  • Patent number: 7798352
    Abstract: A packaging device includes a bottom plate and a mounting plate arranged above the bottom plate at a specific distance form the bottom plate. An article to be transported is placed on the mounting plate. A cushioning member is arranged in a space between the bottom plate and the mounting plate. The cushioning member protects the article from shocks. A reinforcing unit is arranged on the bottom plate in the space between the bottom plate and the mounting plate so that support members of the article rest on the reinforcing unit.
