  The first rotation link 31 is a pair of left and right links, and is formed in a substantially rectangular shape. A first connection member 33 described later is rotatably attached to one end 31a, and a base bracket 36 described later is attached to the other end 31b. In contrast, it is pivotably connected.

  The second rotating link 32 is a pair of left and right links, and is formed in a substantially L shape. A third connecting member 35 described later is rotatably attached to one end 32a, and a base bracket described later is connected to the other end 32b. 36 is pivotally connected to 36.

  The first connecting member 33 and the third connecting member 35 increase the rigidity of the ottoman device 10 by connecting the first rotating link 31 and the second rotating link 32 on the ottoman main body 20 side. 33 is provided with the 1st connection part 33a which enables the connection of the movable mechanism 40 mentioned later.

  The first connecting portion 33a has one end 33b fixed to the first connecting member 33 and the other end 33c rotatably connected to a movable mechanism 40, which will be described later. The connecting portion 33d is connected to the first connecting member 33 in a state where the connecting portion 33d is connected to a substantially extending line with respect to the axial direction of the drive shaft 42 of the movable mechanism 40 and the ottoman body 20 is unfolded. 33d can be rotated so that the connecting portion 33d of the movable mechanism 40 is substantially perpendicular to the axial direction of the drive shaft 42, and the support bracket 21a is moved by rotating the movable mechanism 40.

  The base bracket 36 allows the first rotation link 31 and the second rotation link 32 to be attached to the seat cushion, and the first rotation link 31 and the second rotation link are provided on the end 36a on the ottoman body 20 side. The moving link 32 is rotatably connected, and a second connecting member 34 to be described later is provided at the other end 36b.

  The 2nd connection member 34 is provided with the 2nd connection part 34a which fixes the pivot part 43 which has the movable mechanism 40 mentioned later. Here, the second connecting portion 34 a is fixed to the second connecting member 34 by welding or the like, and is pivotally attached to the pivot attachment portion 43 included in the movable mechanism 40.

  The movable mechanism 40 includes an electric motor 41 that is rotatably connected to a first connecting portion 33a of the first connecting member 33, a drive shaft 42 that rotates as the electric motor 41 is driven, a drive shaft 42, and a screw. The second connecting member 34 includes a pivot attachment portion 43 pivotally attached to a second connection portion 34a.

  The electric motor 41 serves as a power source when the ottoman main body 20 is deployed and stored, and is rotatably connected to a first connecting portion 33a included in the first connecting member 33, and rotates forward or backward. To drive the drive shaft 42 described later.

  The drive shaft 42 has one end 42a connected to the electric motor 41 and the other end 42b screwed to a pivot attachment portion 43 described later. The drive shaft 42 rotates as the electric motor 41 is driven to pivot the electric motor 40 described later. Move toward or away from the landing part 43.

  Since the pivot portion 43 is screwed to the drive shaft 42 and pivotally coupled to the second coupling portion 34a of the second coupling member 34, the electric motor 41 is driven and the drive shaft 42 is rotated. The electric motor 41 can be moved in the direction of the drive shaft 42.

  Therefore, as described above, the movable mechanism 40 rotatably connects the electric motor 41 to the first connecting portion 33a included in the first connecting member 33, and the second connecting portion included in the second connecting member 34. Since the pivot attachment portion 43 is pivotally attached to 34a, when the ottoman main body 20 is deployed and stored, it operates while rotating up and down with respect to the front-rear direction of the ottoman device 10. (Fig. 5)

Next, the operation of the ottoman device 10 described above will be described.
When the ottoman device 10 is moved from the state in which the ottoman main body 20 is stored in the lower part of the seat cushion (FIG. 3) to the state in which it is deployed forward (FIG. 4), the ottoman device 10 drives the electric motor 41 included in the movable mechanism 40 to drive the drive shaft 42. By rotating, the electric motor 41 is moved away from the pivot 43 that is pivotally coupled to the second coupling portion 34 a of the second coupling member 34, and the first pivot link 31 and the second pivot link 32. Is rotated in the direction in which the ottoman body 20 is deployed. As a result, the ottoman body 20 moves forward with respect to the storage position.

At this time, when the electric motor 40 moves far away with respect to the pivot portion 43 pivotally attached to the second coupling portion 34 a of the second coupling member 34, the first coupling portion 33 a is connected to the electric motor 41. Is rotated so as to be substantially perpendicular to one end 33 b fixed to the first connecting member 33, thereby rotating the first connecting member 33. Here, when the first connecting member 33 rotates, the support bracket 21a rotates about the connecting position with the first connecting member 33 as the rotation center, and thus rotates in the direction in which the ottoman body 20 is deployed.

  When the ottoman device 10 is moved from the state where the ottoman main body 20 is deployed forward (FIG. 4) to the state stored in the lower part of the seat cushion (FIG. 3), the ottoman main body 20 deploys the electric motor 41 included in the movable mechanism 40. By driving in the direction opposite to the direction and rotating the drive shaft 42 in the reverse direction, the electric motor 41 is moved closer to the pivot 43 that is pivotally coupled to the second coupling portion 34a of the second coupling member 34 to perform the first rotation. The link 31 and the second rotation link 32 are rotated in the direction in which the ottoman body 20 is retracted. As a result, the ottoman body 20 is stored in the lower part of the seat cushion.

  At this time, when the electric motor 40 approaches the pivot portion 43 pivotally attached to the second coupling portion 34 a of the second coupling member 34, the first coupling portion 33 a is driven by the coupling portion 33 d with the electric motor 40. The first connecting member 33 is rotated by rotating until reaching an approximately extension line with respect to the axial direction of the shaft 42. Here, when the first connecting member 33 rotates, the support bracket 21a rotates about the connecting position with the first connecting member 33 as a rotation center, and thus rotates in a direction to store the ottoman body 20 in the lower part of the seat cushion. To do.

  Therefore, the ottoman device 10 of the present invention performs the operation of moving the ottoman body 20 forward and the operation of rotating the ottoman body 20 in conjunction with the driving of the movable mechanism 40 when the ottoman body 20 is deployed and stored. Is possible. Thus, compared with the conventional structure in which the main link for moving the ottoman body 20 forward and the rotation link for rotating the ottoman body 20 are separately provided, the number of parts can be reduced, so that the structure can be simplified. 10 can be reduced in weight.
