Abstract: In a reel 24 of a lanyard, a cam 46 is rotatable to change an orientation among a free orientation, a locking orientation, and a waiting orientation. The free orientation represents an orientation in which the cam 46 can be rotated in any of directions. The locking orientation represents an orientation in which a locking engagement portion 82 engages with a latching portion 96 of a cam receiver 52. The waiting orientation represents an orientation in which a waiting engagement portion 84 engages with a plate spring 48. When the bobbin rotates in one direction, the cam 46 changes from the free orientation to the waiting orientation. When the bobbin rotates in the other direction, a tip 82a of the cam 46 in the waiting orientation is guided by a guiding surface 100, to change the cam 46 from the waiting orientation to the locking orientation.

Abstract: [OBJECT] To provide a device which is held by vacuum on a wall surface or a window surface of glass of a building, and which is moved along the surface, thereby performing the cleaning operation. [SOLVING MEANS] In three clinging units which are arranged in a row, each of the clinging units includes clinging unit putting forward/backward means for putting the clinging unit in and out in a direction intersecting with the surface. The clinging units adjacent to each other are coupled by transverse expansion and contraction means via the clinging unit putting forward/backward means, so as to constitute a row clinging unit group. In three row clinging unit groups which are arranged in the longitudinal direction, the row clinging unit groups adjacent to each other are coupled by lengthwise expansion and contraction means via the clinging unit putting forward/backward means. Each of the clinging units can be selectively set in one of three states, i.e.

Abstract: A safety belt includes a connecting member including a rope, an attaching portion connected to a first end of the rope and arranged to be attached to a body belt worn around a body of a worker, a hook connected to a second end of the rope, and a load detection portion arranged to detect whether or not a load is applied to the connecting member and to output a load detection signal. The safety belt also includes a control device that includes a receiver unit arranged to receive the load detection signal, a control unit arranged to determine a status of the worker or a status of the safety belt based on the load detection signal, and a notification unit arranged to provide a notification in accordance with control by the control unit corresponding to the determined status.
