(About the outline of the hood structure)
First, an outline of a foldable hood structure in the present embodiment will be described.

  FIG. 1 is a perspective view showing an appearance of a hood 1 according to an embodiment of the present invention. FIG. 2 is a side view showing the structure of the hood 1. FIG. 3 is a perspective view showing the internal structure of the hood 1.

  2 and 3, the hood 1 includes a hood bone 11, 12 whose lower end portions are connected so that the angle between the hood 1 is variable, and a hood cloth 2 passed to the hood bone 11, 12. It has. Each hood bone 11 and 12 has an inverted U-shape. One end and the other end of each hood bone 11 and 12 are connected to each other by a connecting shaft 10 so as to be rotatable. In the present embodiment, the direction in which the hood bones 11 and 12 move away from each other or approach each other is referred to as “front-rear direction”, and the direction connecting the connecting shafts 10 (direction perpendicular to the front-rear direction) is referred to as “left-right direction”. To do.

  The hood cloth 2 typically includes an outer cloth 21 and an inner cloth 22 that cover the outer and inner sides of the hood bones 11 and 12, respectively. The outer cloth 21 and the inner cloth 22 are sewn, for example, at the respective outer peripheral edges.

  Since the hood 1 is foldable, the hood 1 includes a link mechanism 3 as an open state maintaining member for maintaining the hood bones 11 and 12 in an open state, and an operation unit 4 attached on the link mechanism 3. And are provided. The link mechanism 3 is disposed so that both ends thereof are in contact with the hood bones 11 and 12. The link mechanism 3 is provided on both sides (left and right direction) of the hood 1 and can maintain the open state by fixing the positions of the hood bones 11 and 12. A specific structural example of the link mechanism 3 will be described later.

  The operation unit 4 changes the position of the link mechanism 3 by being operated by a user's hand. That is, according to the operation of the operation unit 4, the hood bones 11 and 12 are opened or released. The operation unit 4 is spherical, for example.

  Note that the operation unit 4 may be provided only on one side of the hood 1 as long as the operations of the two link mechanisms 3 provided on the left and right sides are interlocked.

  Here, the link mechanism 3 is hidden by the hood cloth 2 as shown in FIG. 1, and only the operation unit 4 is exposed from the hood cloth 2. That is, in the present embodiment, the link mechanism 3 is disposed between the outer cloth 21 and the inner cloth 22, and the outer cloth 21 of the hood cloth 2 has a concealing portion 23 that hides the link mechanism 3 and an operation. An opening 25 that exposes only the portion 4 is provided.

  The concealment portion 23 is formed in a portion that covers the movable range of the link mechanism 3. The width of the opening 25 is preferably smaller than the width (length in the front-rear direction) of the operation unit 4. In the present embodiment, the opening 25 is a slit that extends along the moving direction of the operation unit 4. In order to smoothly guide the movement of the operation unit 4, it is desirable to sew and harden the peripheral portion of the opening 25.

  Thus, by concealing the link mechanism 3 in the hood cloth 2 and exposing only the operation section 4, the aesthetic appearance of the hood 1 is improved without deteriorating operability.

  The hood 1 can be attached to an infant seat. Therefore, the hood 1 includes, for example, a sleeve as the attachment member 6 for attaching the hood 1 to the infant seat. The attachment member 6 is attached to the other end of a support plate 61 in which a connecting shaft 10 that connects the hood bones 11 and 12 is fixed to one end.

  With reference to FIG. 3, the hood 1 may further be provided with a wire 13 between the hood bones 11 and 12. The wire 13 has an inverted U shape that is approximately the same size as the hood bones 11 and 12. Thereby, the wire 13 also functions as a hood bone. The lower end portion of the wire 13 may be fixed to the connecting shaft 10 as shown in FIG. 3, or may be fixed to the back side of the outer cloth 21 of the hood cloth 2.

  Thus, when the wire 13 is provided in the hood 1, since the upper part of the hood cloth 2 (outer cloth 21) follows the wire 13 in the open state, the hood cloth 2 can be prevented from drooping. As a result, the beauty of the hood 1 is further enhanced.

(Example of structure around the link mechanism)
