Description

  The present invention relates to a hanger that suspends a suspended body, and relates to a hanger that can be connected to the suspended body with a simple operation.

  Conventionally, for example, when an object, which is a suspended body, is connected to a suspended body such as a belt to be lifted or moved, it is a hook-like mechanical component that suspends the suspended body. A hook or the like is used.

There are various types of hooks as the above-described suspension tools, for example, a carabiner used as a mountain climbing bracket disclosed in Patent Document 1 below. As shown in FIG. 13, the carabiner 100 is substantially configured by a finger 103 having a circular cross section supported rotatably on a lower end portion of a C-shaped body 102 having an opening 101 via a spindle 104. . Note that the finger 103 is urged so as to close the opening 101 by a return spring 105.

JP 7-47150 A Japanese Patent No. 2002-65762

  However, in the conventional lifting device (carabiner) as described above (disclosed in Patent Document 1), the opening 101 is connected to the object while the opening 101 is kept open, so that one hand can resist the urging force. Then, the finger 103 is pressed to hold the opening 101 open, and the carabiner 100 and the ring-shaped portion of the object are connected with the other hand in this state. If work is performed using both hands in this way, the object and the carabiner 100 can be easily connected. However, if this connecting operation is performed with only one hand, a certain amount of labor is required. That is, this carabiner 100 is inconvenient to handle with one hand.

  In addition, the above-described hanging tool is widely used in welfare mechanisms. For example, Patent Document 2 discloses an autonomous nursing lifter that connects and conveys a physically handicapped person by a carabiner that is a hanging tool. However, for physically handicapped people who have difficulty with their hands and half, their muscle strength is weaker and their fingers are handicapped compared to normal subjects. Although it is difficult only to hold the opening, it is not easy to connect the carabiner 100 and the object with the other hand, and it is a significant physical burden.

Thus, when the object O is inserted through the hook portion 2, the opening 3 is automatically closed. Therefore, it is possible to prevent the suspension 1 and the object O from being unintentionally disconnected during use. Furthermore, even if the user of this hanging tool 1 is a physically handicapped person, for example, a hand or a half body, it can be used easily.

  Further, since the connecting pin 20 (fulcrum E) provided between both ends of the operation unit 19 is located on the lower end side from the center, the operation end 21 and the fulcrum E of the operation unit 19 serving as an action point are provided. The distance with the connecting pin 20 becomes longer. As a result, the moment of the operation end 21 is increased, and the operation unit 19 can be rotated with a small force. That is, the opening 3 can be opened with a minute force.

  Further, by using the magnets M and M and the link mechanism, a mechanism for holding the finger portion 7 at a position where the opening 3 is opened and a mechanism for moving the finger portion 7 to a position where the opening 3 is closed are simplified. It can be configured. Thereby, the cost concerning this hanging tool 1 can be reduced, and it can obtain now at low cost.

  In the first embodiment, the holding means 18 for holding the finger portion 7 at the open position of the opening portion 3 includes magnets M, M provided on the finger portion 7 and the load receiving portion 15 respectively. However, it is good also as a structure by which either one or both of the finger part 7 and the load receiving part 15 are formed with the magnetic body. Thereby, in addition to the effect that the open state of the opening 3 is maintained as described above, the effect that the number of parts can be reduced and the cost can be obtained at a low cost is obtained.

  Moreover, in this 1st Embodiment, although the connection structure of the finger part 7 and the operation part 19 becomes a structure where the connection convex part 9 of this finger part 7 meshes with the connection recessed part 23 of the operation part 19. The finger part 7 and the operation part 19 are not limited to this as long as the finger part 7 and the operation part 19 are connected so as to be interlocked. For example, the connection part of the finger part 7 and the operation part 19 is good also as a structure which has meshed | engaged with the gearwheel.
