Chair and cover member of the chair
A chair according to the present invention includes: a leg 1 ; a leg support pole 13 ; a support base 4 ; a movement mechanism 5 located below a seat 2 , the movement mechanism 5 provided with plural movement parts 5 A, 5 B configured to allow the seat 2 to move in a certain area along a predetermined trajectory in a front-rear and left-right directions between the support base 4 and the seat 2 , the movement mechanism 5 being a support mechanism configured to support the seat 2 so that the seat 2 moves in the front-rear direction and left-right directions; and plural cover members 71, 72 arranged corresponding to the plural movement parts 5 A, 5 B. The plural cover members 71, 72 are configured to move relatively in accordance with movement of the plural movement parts 5 A, 5 B and cover the support mechanism 5.
1. A chair comprising:
a leg arranged on a floor surface;
a leg support pole provided to stand from the leg;
a support base provided on an upper end of the leg support pole;
a movement mechanism located below a seat the movement mechanism including a plurality of movement parts configured to allow the seat to move in a certain area along a predetermined trajectory in a front-rear direction and a left-right direction between the support base and the seat the movement mechanism being a support mechanism configured to support the seat movably in the front-rear direction and the left-right direction: and
a plurality of cover members arranged corresponding to the plurality of movement parts,
wherein the plurality of cover members is configured to move relatively in accordance with movement of the plurality of movement parts and cover the support mechanism,
wherein the movement mechanism includes a left-right support part to support the seat movably in the left-right direction, and a front-rear support part to support the seat movably in the front-rear direction,
wherein the plurality of cover members includes a left-right cover member attached to the left-right support part, and a front-rear cover member attached to the front-rear support part,
wherein the left-right cover member and the front-rear cover member move relatively while coming close to each other with a gap between the left-right cover member and the front-rear cover member,
wherein the front-rear cover member is provided above the left-right cover member, and
the chair further comprising an interpolation cover member interposed between the left-right cover member and the front-rear cover member.
2. The chair according to claim 1 , wherein the plurality of cover members configured to cover the movement mechanism is formed by a combination of a member to move in a first direction and a member to move in a second direction orthogonal to the first direction.
3. The chair according to claim 1 , wherein in accordance with a relative movement between the left-right cover member and the front-rear cover member, the interpolation cover member moves in a different direction from the movement of the left-right cover member and the front-rear cover member.
4. The chair according to claim 1 , further comprising a fixation cover member configured to cover the support base and so as not to move in accordance with movement of the seat.
5. The chair according to claim 1 , wherein on a facing surface where the left-right movement member is adjacent to the front-rear movement member, an opening for inserting a connection member to relatively and movably connect the left-right movement part to the front-rear movement part so that the movement parts move relatively is disposed.
6. The chair according to claim 5 , further comprising a fixation cover member configured to cover the support base and so as not to move in accordance with movement of the seat.
