Reclining device
View Patent ↗A reclining apparatus which includes guide members ( 20 ) that move forward and backward on opposite sides of a bottom plate ( 3 ). The guide members ( 20 ) are moved forward and backward by a roller ( 21, 22 ) that is slidable and rotatable along a surface of the bottom plate ( 3 ). A seat member ( 30 ) and a back member ( 50 ) are attached to the guide members ( 20 ) and, accordingly, are able to move smoothly forward and backward without excessive force.
1. A reclining apparatus comprising:
guide members disposed on opposite sides of a bottom plate so as to be movable forward and backward;
a back member, which supports a person's back, being rotatably connected to the guide members and being supported with respect to a foot member so as to be reclinable;
front and back rollers being at least one of slidable and rotatable along the bottom plate for moving the guide members forward and backward; and
a brake shoe, capable of contacting the bottom plate, and a seat member are attached to the guide members;
wherein the brake shoe, when in a locked state, retains the back roller against the bottom plate and, when in an unlocked state, permits movement of the back roller along the bottom plate by rocking of the guide members.
2. The reclining apparatus according to claim 1 , further comprising:
a connection plate inserted in a rear end of the seat member so that the connection plate can abut against the guide members; and
an auxiliary roller attached to the guide members on a rear side of an axial member so that the auxiliary roller can roll along the bottom plate, when the guide members rotate in a clockwise direction.
3. The reclining apparatus according to claim 1 , wherein the reclining apparatus further comprises a roller plate having a convex curved shape.
4. The reclining apparatus according to claim 1 , wherein the bottom plate has a front-rising linearly inclined shape.
5. The reclining apparatus according claim 1 , further comprising an armrest part formed so as to be movable forward and backward with respect to the foot member so that at least one of a side plate and the seat member can be moved forward and backward via a connection member attached to the armrest part.
6. A reclining apparatus comprising:
guide members disposed on opposite sides of a bottom plate so as to be movable forward and backward;
a back member, which supports a person's back, and is rotatably connected to the guide members via an axial member which is supported so as to be reclinable with respect to a foot member;
at least one of an upper brake shoe, which can contact a front surface of the bottom plate via a front press member attached to the guide members, and a lower brake shoe, which can contact a back surface of the bottom plate via a back press member attached to the guide members; and
an auxiliary roller attached to the guide members so as to be at least one of slidable and rotatable along the front surface of the bottom plate in a position on the rear side of the axial member;
wherein the brake shoe retains the roller in a locked state, and permits movement of the roller, in an unlocked state by rocking of the guide members.
