  When the lock mechanism is released at the footrest position and an upper load is applied to the ottoman main body 30, the links 22, 23, 24, 25 are interlocked against the urging force of the damper 26 and move to the storage position. The ottoman device 10 is fixed at the storage position by operating the lock mechanism at the storage position.

In the ottoman device 10 according to the present invention, the ottoman body 30 can be expanded and contracted in the front-rear direction. Hereinafter, the ottoman body 30 will be described.
As shown in FIG. 2, the ottoman main body 30 includes a base portion 40 and a slide portion 31 that slides relative to the base portion 40. Although not shown, the ottoman main body 30 is provided with a pad material or a surface material that covers the base portion 40 and the slide portion 31.

  FIG. 3B shows the shortest position where the slide part 31 is arranged at the rearmost position in the footrest position, and FIG. 3C shows the longest position where the slide part 31 is arranged most forward. 4 is a view taken along the arrow IV in FIG. 3 (b), and FIG. 5 is a view taken along the arrow V in FIG. 3 (c). 4 and 5, the upper side is the rear side, and the lower side is the front side.

  The base portion 40 is provided with an attachment portion 41 to which the links 23 and 24 are attached. Grooves 42 and 43 penetrating the base 40 are formed in the front-rear direction. Rails 44 for sliding the slide portion 31 are provided on the left and right side portions of the base portion 40.

  A slide mechanism that slides the slide portion 31 relative to the base portion 40 is provided on the back surface of the base portion 40. The slide mechanism is generally composed of links 51 and 52, a spring 54, a cable 61, a tube 62, and the like.

  The link 51 has two arms 51a and 51b, and is attached to the back surface of the base 40 so as to be swingable at the center thereof. 4 and 5, when the link 51 rotates counterclockwise, the tip of the arm 51a moves backward and the tip of the arm 51b moves forward. When the link 51 rotates clockwise, the tip of the arm 51a moves forward and the tip of the arm 51b moves forward. Move backwards.

  An engaging portion that engages with the tip of the cable 61 is provided at the tip of one arm 51a. The cable 61 is inserted into the tube 62 and the other end is wound around a handle shaft of a spring brake 60 (see FIG. 1) provided on the seat 2. One end of the tube 62 is fixed to the base 40 and the other end is fixed to the spring brake 60 of the seat 2. The cable 61 is slid in the length direction with respect to the tube 62 by operating the handle of the spring brake 60. The tube 62 is attached to the base 40 so that the cable 61 is drawn out backward. When the cable 61 is drawn out from the tube 62, the tip of the cable 61 moves backward.

One end of a link 52 is swingably attached to the tip of the other arm 51b. A screw 53 inserted into the groove 42 is provided at the other end of the link 52. The end portion of the link 52 where the screw 53 is provided slides back and forth along the groove 42 because the screw 53 is inserted into the groove 42.
The tip of the screw 53 inserted through the groove 42 is fixed to the slide portion 31 on the front side of the base portion 40.

Rail guides 32 are provided on the left and right side portions of the slide portion 31, and the rail guides 32 slide relative to the rails 44 provided on the base portion 40.
A spring tension portion 33 is attached to the back surface of the slide portion 31. The spring tension portion 33 is inserted into the groove 43 of the base portion 40 and slides back and forth along the groove 43.
One end of a spring 54 is attached to the rear end portion of the spring tension portion 33 on the back side of the base portion 40. The other end of the spring 54 is fixed to a spring fixing portion 45 provided on the back surface of the base portion 40. The spring 54 expands and contracts as the spring tension portion 33 slides back and forth.

  Since the spring 54 is extended more than the natural length, the spring tension portion 33, the slide portion 31, and the link 52 are urged forward, and the link 51 is urged counterclockwise in FIGS. . However, since the tension of the cable 61 engaged with the tip of the arm 51a balances with the tensile force of the spring 54 that urges the link 51 in the counterclockwise direction, the slide portion 31 is stationary unless the tip of the cable 61 is moved. ing. In addition, in the shortest position shown in FIG. 4, the length of the cable 61 drawn out from the tube 62 is the shortest, and in the longest position shown in FIG. 5, the length of the cable 61 drawn out from the tube 62 is the longest.

Next, expansion and contraction of the ottoman body 30 by the slide mechanism will be described.
When the slide part 31 is moved forward, the link 51 is allowed to rotate by operating the handle of the spring brake 60 to increase the feeding length of the cable 61 and moving the tip of the cable 61 backward. Then, the slide portion 31, the spring tension portion 33, and the link 52 move forward by the tensile force of the spring 54, the tip of the arm 51b is pulled forward by the link 52, and the link 51 rotates counterclockwise in FIGS. The tip of the arm 51 a moves backward to the position of the tip of the cable 61.

  When the slide part 31 is moved backward, the handle of the spring brake 60 is operated to reduce the feeding length of the cable 61, and the tip of the cable 61 is moved forward. Then, the arm 51a is pulled forward by the cable 61, the link 51 rotates clockwise in FIGS. 4 and 5, the tip of the arm 51b pulls the link 52 rearward, and the slide portion 31 and the spring tension portion 33 are moved. The spring 54 is retracted and the spring 54 is extended against the elastic force of the spring 54.

Thus, since the displacement amount of the slide part 31 depends on the feeding length of the cable 61, the sliding part 31 can be moved forward or backward by an arbitrary displacement amount by changing the feeding length of the cable 61.
Here, since the cable 61 is wound around the handle shaft of the spring brake 60, the extended length of the cable 61 can be set arbitrarily.
Therefore, according to the present invention, by operating the handle of the spring brake 60 provided on the seat 1 and winding the cable 61 around the handle shaft by an arbitrary length, the slide portion 31 is moved in the direction opposite to the biasing direction. Since it is driven and the cable 61 is drawn out from the handle shaft by an arbitrary length to allow the slide portion 31 to move in the urging direction, the slide portion 31 can be fixed at an arbitrary position in the front-rear direction.

In the above embodiment, the slide portion 31 is urged forward with respect to the base portion 40 by the spring 54, the slide portion 31 is advanced by pulling out the cable 61, and the slide portion 31 is pulled by pulling the cable 61. On the contrary, the slide portion 31 is urged backward with respect to the base portion 40 by the spring 54, the slide portion 31 is moved backward by feeding the cable 61, and the slide portion is pulled by pulling the cable 61. You may move forward.
Further, other specific detailed structures can be appropriately changed.
