  • Patent number: 11958720
    Abstract: There is provided a vibration suppression device for a rope-like body of an elevator that can inhibit displacement of the rope-like body from becoming unstable due to amplification of the displacement and can make a movable range of the rope-like body wider. A vibration suppression device (20) includes a movable unit and a stopper. The movable unit can move in a direction in which a distance from an equilibrium position (19) of the rope-like body changes. The stopper restricts movement of the movable unit to a position closer than a first distance (d1) from the equilibrium position (19). The movable unit includes a displacement amplifier and a restriction member. The displacement amplifier is arranged to be directed to a first position (P1) of the rope-like body. The displacement amplifier amplifies displacement of the rope-like body. The restriction member inhibits the rope-like body from approaching the displacement amplifier.

  • Publication number: 20230220865
    Abstract: A screw nail includes a nail shaft portion extending along one direction, and a head portion whose diameter is enlarged along other direction orthogonal to an extension direction. A sharp tip end portion is formed on one end side of the nail shaft portion, and the head portion is formed at an end portion on the other end side. The nail shaft portion is formed with a screw thread, and the head portion is formed with an engaging portion capable of engaging with a rotary tool. A convex portion protruding along an axis direction of the nail shaft portion is formed on an end surface of the head portion. A concave portion that is concave with respect to the convex portion is formed between the convex portion and the engaging portion. A virtual plane specified by vertexes of the convex portion is a plane orthogonal to the axis direction.

  • Patent number: 11279014
    Abstract: A gas combustion type driving tool includes an output unit, a grip, a fuel container storage unit, a battery mounting unit and a coupler. The output unit includes a combustion chamber. The grip is connected to a lower surface of the output unit. A fuel container is detachably attached to the fuel container storage unit. A battery pack is detachably attached to the battery mounting unit. The coupler is configured to take air in. The fastener is driven out by combustion pressure when mixed gas of combustible gas supplied from the fuel container and compressed air supplied from outside via the coupler is ignited. The coupler is disposed on a lower end side of the grip. The gas combustion type driving tool includes a pipe configured to connect the coupler and the combustion chamber.
