  "abstract": "To provide a luggage hook of improved ease of use. A luggage hook 10 that is detachably attachable to an attachment location, comprising: a base 20; a belt 81 that is attached to the attachment base 20 and wrapped around the attachment location; a primary hook member 60 comprising a cylindrical primary neck section 61 attached to the base so as to be rotatable around a central axis of rotation R, with a partially open ring-shaped primary hook body 64 being connected to the primary neck section; and a secondary hook member 70 comprising a cylindrical secondary neck section 71 rotatably fitted into the primary neck section, with a partially open ring-shaped secondary hook body 73 being connected to the secondary neck section.",
  "claims": [
    "1. A luggage hook for detachably attaching to an attachment location, comprising: a base (20); a belt attached to the base (20) for wrapping around the attachment location; a primary hook member (60) comprising a cylindrical primary neck section (61) attached at a proximal end thereof to the base (20), and an upward-opening primary hook body (64) attached to a lower end of the primary neck section (61); and a secondary hook member (70) comprising a secondary neck section (71) attached to the primary neck section (61), and an upward-opening secondary hook body (73) attached to the secondary neck section; the primary hook body (64) and the secondary hook body (73) being configured so that one or both thereof rotate relative to the base (20), being provided so that positions thereof in a vertical direction partially overlap, but so as not to interfere with each other even when one or both thereof are rotated relative to the base (20), and being configured so that, when rotational-direction positions thereof are aligned, the secondary hook body (73) narrows and blocks an open part (65) of the primary hook body (64).",
    "2. The luggage hook according to claim 1, wherein: when the rotational-direction positions thereof are aligned, the secondary hook body (73) narrows and blocks the open part (65) of the primary hook body (64) by 50% or more.",
    "3. The luggage hook according to claim 2, wherein: when the rotational-direction positions thereof are aligned, the secondary hook body (73) narrows and blocks the open part (65) of the primary hook body (64) by 75% or more.",
    "4. The luggage hook according to claim 1, wherein: the secondary hook body is formed so as to have a smaller outer shape that the primary hook body.",
    "5. The luggage hook according to claim 1, wherein: the center of the primary hook body is displaced from a central axis of rotation toward the open part of the primary hook body; and the center of the secondary hook body is displaced from the central axis of rotation toward an open part of the secondary hook body.",
    "6. The luggage hook according to claim 1, wherein: the primary hook body has an upward-opening substantially letter-C shape that protrudes in different directions with the rotation axis in between; and the secondary hook body has an upward-opening letter-J shape that protrudes to only one side of the axis of rotation.",
    "7. The luggage hook according to claim 1, wherein: a torque necessary to rotate the primary hook body relative to the base is 5-40 cN·m.",
    "8. The luggage hook according to claim 7, wherein: a torque necessary to rotate the secondary hook body relative to the primary hook body is 5-40 cN·m.",
    "9. The luggage hook according to claim 1, wherein the belt has a hook surface of a hook-and-loop fastener formed on an entirety of one side thereof, and a loop surface of the hook-and-loop fastener formed on an entirety of the other side thereof.",
    "10. The luggage hook according to claim 1, further comprises a reinforcing belt for reinforcing joined parts of the belt wrapped around the attachment location; and wherein the reinforcing belt is connected at one end to an outer surface of the belt, and is longer than a length from a connecting part of the reinforcing belt to one end of the belt."

  "description_excerpt": "The present invention relates to a luggage hook that attaches to a stroller or shopping cart and on which baggage such as bags, shopping bags, and the like can be hung, and, in particular, to a luggage hook of improved ease of use.\n\nWhen using a stroller or shopping cart, one may hang bags, shopping bags, or the like from the handlebar thereof. In such cases, it is convenient to be able to attach a detachable luggage hook thereto, and suspend bags from the luggage hook. For this reason, various types of luggage hooks have been proposed.\n\nLuggage hooks of this sort are constituted by a combination of an attaching part that fastens onto a handlebar, and a hook part, attached to the attaching part, that has a letter-S shape either overall or in its lower half. The hook part is swingably attached to the attaching part, and is capable of suspending a bag in the desired direction (for example, see Patent Document 2). However, only one item of baggage can be hung on one hook part, thus necessitating additional luggage hooks if there are multiple items of baggage. Moreover, if the hook part is fixed in place, the direction from which baggage is hung becomes fixed; thus, hooks that are capable of rotating around the vertical axis have been proposed (for example, see Patent Document 1).\n\nHowever, depending on the position of the center of gravity of the item of baggage, the hook part may rotate around the axis of rotation, resulting in a problematic lack of baggage stability. There also exists a type that uses hook-and-loop fasteners to fasten to the handlebar (for example, see Patent Document 3).",
