The ottoman body 30 will be specifically described.
FIG. 3 is an exploded perspective view of the ottoman body 30 and the link mechanism 20. The ottoman main body 30 includes a base 31, a linear guide 32, a leg receiving portion 33, and the like. Here, the base part 31 has the attachment part 31a and the side wall part 31b provided in the state stood with respect to the attachment part 31a in the right-and-left both sides of the attachment part 31a. A base 31 is attached to the front portion of the seat bottom 2 via the link mechanism 20. Specifically, the attachment portion 31 a is fixed to the link 26 of the link mechanism 20, and the base 21 of the link mechanism 20 is attached to the tilt frame 51.

  A pair of linear guides 32 are provided on the left and right sides of the base 31. Since the linear guide 32 is provided with a leg receiving portion, the linear guide 32 is sandwiched between the side wall portion 31 b and the leg receiving portion 33. Specifically, as shown in FIG. 4, the carriage 32 a of the linear guide 32 is formed in a C shape when viewed from the front, and the carriage 32 a is fixed to the left and right leg receiving portions 33 and extends forward and backward. . The slide rail 32b of the linear guide 32 is held by the carriage 32a, and the carriage 32a is guided back and forth along the slide rail 32b. The slide rail 32b is fixed to the left and right side wall portions 31b. Since the carriage 32 a is guided by the slide rail 32 b, the leg receiving portion 33 can slide back and forth with respect to the base portion 31.

  By providing the linear guide 32 between the base portion 31 and the leg receiving portion 33, the slide of the leg receiving portion 33 becomes smooth. Therefore, the trouble of finely adjusting the gap between the base portion 31 and the leg support portion 33 can be saved. Further, as shown in FIG. 4, the linear guide 32 is attached in a form standing upright with respect to the slide surface of the leg receiving portion 33, so that the load when the leg is placed on the ottoman main body 30 is sufficiently increased It comes to be supported by.

  L-shaped connection fittings 34 are respectively attached to the leg receiving portions 33. The attachment positions in the front-rear direction of the connection fitting 34 are aligned on the left and right. Furthermore, the ottoman main body 30 is configured by attaching a cushion to the leg receiving portion 33.

FIG. 5 is a bottom view of the ottoman body 30, and the bottom is the front. A link mechanism 20 is located in front. Guide brackets 42a, 42b, 42c, and 42d , which are guide portions, are attached to the four corners of the base portion 31, respectively. Each of the guide fittings 42a, 42b, 42c, and 42d is a member bent in an arc shape, and the wire 40 can be gently bent in a right angle direction. The wire 40, which is a flexible wire, is hooked in order from the guide fitting 42a to the guide fittings 42b, 42c, and 42d , so that the wire 40 is routed in an N-shape on the base 31. Both ends of the wire 40 are connected to form an annular shape, and are connected to an operation unit 44 provided on the side of the seat bottom shown in FIG.

  Since the wire 40 is routed in an N-shape on the base 31, a right portion 40a extending linearly in the front-rear direction in the vicinity of the right linear guide 32 is provided between the guide fitting 42c and the guide fitting 42d. Between the guide fitting 42a and the guide fitting 42b, there is a left portion 40b extending linearly in the front-rear direction in the vicinity of the left linear guide. Both the right portion 40a and the left portion 40b of the wire 40 extend parallel to the sliding direction of the leg receiving portion. The right connecting portion 34a supports the right portion 40a of the wire 40 and the left connecting portion 34 supports the left portion 40b of the wire 40, whereby the wire 40 and the leg receiving portion 33 are connected.

  The wire 40 arranged obliquely between the guide fitting 42b and the guide fitting 42c is covered with an outer casing 41a. Similarly, the wire 40 between the guide fitting 42a and the operation portion 44 is covered with an outer casing 41b, and the wire 40 between the guide fitting 42d and the operation portion 44 is covered with an outer casing 41c.

  A wire play absorbing member 43 is provided at the center of the outer casing 41a. The wire play absorbing member 43 adjusts the length of the outer casing 41a with an adjusting bolt and nut, and the play of the wire 40 can be reduced by making the outer casing 41a longer.

  FIG. 6 is a perspective view of the operation unit 44 for operating the wire 40. The operation unit 44 is attached to the side portion of the side frame 50. The operation unit 44 has a drum 44a around which a wire 40 is wound, and a regulator handle is attached to a rotating shaft 44b of the drum 44a. When the regulator handle is rotated, the drum rotates and the one wire 40 connected to the operation unit 44 is wound up. Since the wire 40 is continuous, the other wire 40 connected to the operation unit is pulled. In this way, the wire 40 moves inside the outer casings 41a, 41b, 41c. Of course, the wire 40 can be moved in the reverse direction by rotating the regulator handle in the reverse direction.

Next, expansion / folding of the link mechanism will be described.
When the lock of the length adjusting device 28 is released, the link mechanism 20 can be deployed. The link mechanism 20 is deployed forward by the extension force of the length adjusting device 28, and the link 26 hangs down from the front portion of the seat bottom 2 shown in FIG. 2 to the front of the seat bottom 2 shown in FIG. It moves to the state which extended ahead from the part. In this state, when the length adjusting device 28 is locked, the state of the link mechanism 20 is maintained, and a leg can be placed.

  When the lock of the length adjusting device 28 is released in the state shown in FIG. 7, the link mechanism 20 can be folded this time. By applying a downward load to the ottoman body 30, the length adjusting device 28 contracts, and the link 26 moves from the expanded state of FIG. 7 to the folded state shown in FIG.

Next, the operation of the ottoman body 30 will be described.
Since the wire 40 is arranged in an N shape on the base 31, when the operation unit 44 is rotated, the wire 40 of the right portion 40a and the wire 40 of the left portion 40b are simultaneously moved in the same direction. When the wire 40 starts to move, the leg receiving portion 33 connected to the wire 40 by the connection fitting 34 slides with respect to the base portion 31, and moves from the position shown in FIG. 5 to the position shown in FIG. Since the leg receiving portion 33 is pulled simultaneously from the two left and right locations, the force applied is not biased and slides smoothly. If the rotation of the operation unit 44 is stopped halfway, the leg receiving unit 33 can be stopped at an arbitrary position.

  Further, since both ends of the wire 40 are connected to each other and are annular, when the regulator handle of the operation unit 44 is rotated in the reverse direction, the wire 40 also moves in the reverse direction, and the leg receiving portion 33 is slid in the position shown in FIG. Then, slide toward the original position shown in FIG. Even when sliding in the opposite direction, the leg receiving portion 33 is pulled simultaneously from the two left and right locations, so that the movement is as smooth as when sliding forward. Further, even if the movement of the wire 40 is shifted between the right portion 40a and the left portion 40b during repeated use, it can be easily restored by adjusting the wire play absorbing member 43.

  With such a mechanism, the stationary position of the ottoman body 30 can be smoothly adjusted in the front-rear direction between the position shown in FIG. 7 and the position shown in FIG. I can rest.

  In the above embodiment, the wire is bent with the metal fitting, but the present invention is not limited to this, and the wire is guided by integrally forming a guide on a resin cover. Therefore, it is possible to obtain a structure that further saves space. Further, the wires may be arranged in an inverted N shape. In addition, it is needless to say that specific detailed structures and the like can be appropriately changed.
