Detailed Description

The embodiments described in the present specification and the structures shown in the drawings are only preferred examples of the disclosed invention, and various modifications that can replace the embodiments and drawings of the present specification may exist at the time of filing the present application.

Hereinafter, a reclining chair according to the present invention will be described in detail based on embodiments described below with reference to the drawings.

Referring to fig. 2 to 7, a reclining chair according to an embodiment of the present invention includes: a main body 100 fixed to a ground surface; a rotation member 130 provided to be rotatable in a vertical direction around a first rotation shaft 131 parallel to an upper side of the main body 100; a backrest part 110 having a lower end coupled to the rotating member 130 and rotating together with the rotating member 130; a rotary seat part 120 having a rear end part relatively rotatably connected to a rotary member and rotating in conjunction with the rotary member 130; and a driving unit providing power to rotate the rotating member 130.

The main body portion 100 is an iron structure capable of supporting the entire reclining chair on a floor surface, and may include: a base 101 placed on a ground surface; a column 102 extending from a center portion of the base 101 to an upper side; and a base frame 103 disposed at an upper end of the column 102.

The backrest portion 110 is for supporting a back portion of a user, and includes: a back frame 111 extending in the up-down direction and supporting a back portion of a user; the connection frame 112 is formed in a substantially "l" shape at a lower end portion of the back frame 111, and is connected to the rotation member 130. The back frame 111 is disposed in a state of being inclined at an initial disposition angle by a certain angle (e.g., about 110 °) with respect to the ground. The back frame 111 is covered with an auxiliary material of a resin material such as plastic to comfortably support the back portion of the user, and an inner material thereon, such as polyurethane foam, sponge, styrol foam, or the like, may be covered with an outer cover made of napping (tricot) made of polyester, synthetic leather, natural leather, or the like.

In addition, a head rest portion 116 and an arm rest portion 115 capable of supporting the head and the arms of the user are connected above and below the backrest portion 110, respectively.

In order to enable the reclining chair to perform a massage function, a massage module mounted on a known massage chair, a rail structure and a transfer means for the up-and-down movement of the massage module, etc. are provided inside the backrest part 110 to massage the shoulders, back and waist by the up-and-down movement of the massage module, or an air bag may be provided to perform an expansion and contraction movement by supplying and discharging air to perform a finger pressure on each part of the body.

The swivel seat portion 120 has its rear end portion rotatably connected to the swivel member 130 through the second swivel shaft 120a, and is linked with the swivel member 130 to be moved rotationally up and down with respect to the base frame 103. The rotating seat portion 120 may include: a seat frame 121 having a quadrangular frame shape to support buttocks and thighs of a user; and a connecting bracket 123 extending rearward at a rear end of the seat frame 121 and connected to the swivel member 130. The connection bracket 123 has a rod shape that extends rearward by a predetermined length at the rear end of the seat frame 121 and is inclined slightly downward, and a shaft connection hole 123a for connecting the second rotation shaft 120a is formed through the rear end of the connection bracket 123. Side panels 122 having a flat plate shape may be formed at both sides of the seat frame 121 to face both sides of the base frame 103.

In an initial state where the angle adjustment is not performed, the rotary seat portion 120 may be disposed substantially parallel to the ground, and, as an embodiment, may be disposed to be slightly inclined to an upper side by a predetermined angle (for example, about 10 °) with respect to the ground.

Two support links 125 are connected to the side panels 122 of the rotary seat portion 120 for supporting the front of the rotary seat portion 120 when the rotary seat portion 120 rotates together with the rotary member 130. Each support link 125 has a lower end rotatably connected to both side surfaces of the base frame 103 by a hinge pin 125a and an upper end rotatably connected to a front side of the side panel 122 by a hinge pin 125b, and when the rear end portion of the rotary seat portion 120 receives a rotational force from the rotary member 130 and rotates to the upper side, it is possible to have an effect of providing an auxiliary rotational force even in front of the rotary seat portion 120 by supporting the front portion of the rotary seat portion 120 with respect to the base frame 103.

In addition, a guide unit for guiding the rotational movement of the rotational seat portion 120 with respect to the base frame 103 while supporting the rotational seat portion 120 with respect to the base frame 103 may be provided between the rotational seat portion 120 and the base frame 103. The guide unit serves to prevent a phenomenon that the swivel seat part 120 is unintentionally lowered due to the user's weight when the backrest part 110 is tilted backward.

In this embodiment, the guide unit may include: a guide hole 126 formed in a curved shape while the side panel 122 of the swivel seat portion 120 extends in the front-rear direction; a guide link 127 having a lower end rotatably connected to a side of the base frame 103 by a hinge pin 125 a; a guide pin 128 inserted into the guide hole 126 at an upper end of the guide link 127 and sliding along the guide hole 126 when the rotary seat portion 120 rotates. The hinge pin 125a connecting the guide link 127 to the base frame 103 may be the same hinge pin as the hinge pin 125a connecting the lower end portion of the support link 125 to both side surfaces of the base frame 103. That is, the lower end portion of the guide link 127 and the lower end portion of the support link 125 may be rotatably connected to the side of the base frame 103 by the same hinge pin 125 a.

The rotating member 130 may be formed of a quadrangular frame or a plate, and both side end portions are rotatably connected to both side rear end portions of the base frame 103 through first rotating shafts 131 parallel to the ground so as to perform an up-and-down rotating motion with the first rotating shafts 131 as a center with respect to the base frame 103. In addition, the rotary member 130 is formed with a backrest coupling hole vertically penetrating and coupled when the lower end portion of the coupling frame 112 of the backrest portion 110 is inserted, and two coupling pieces 133 are formed at both side end portions of the upper portion to protrude upward, and the rotary member 130 and the rotary seat portion 120 are coupled to be rotatable about the second rotary shaft 120a by inserting the second rotary shaft 120a in a state that the holes of the coupling pieces 133 are aligned with the shaft coupling holes 123a of the coupling bracket 123 of the rotary seat portion 120.

Therefore, when the rotation member 130 is rotated about the first rotation shaft 131 by the driving unit, the backrest portion 110 is rotated in the vertical direction together with the rotation member 130, and at the same time, the rotary seat portion 120 is also rotated in the vertical direction about the second rotation shaft 120a to adjust the angle. At this time, the swivel seat portion 120 guides the swivel motion through the guide hole 126 and the guide link 127 constituting the guide unit, and the swivel seat portion 120 has a rotation angle smaller than that of the swivel member 130.

The driving unit providing the rotational force to the rotating member 130 may be constituted by various known linear motion devices, and in this embodiment, by an actuator 135 including an operating lever 136 that extends and contracts in the front-rear direction. The actuator 135 may be a linear motion device having a screw shaft that is rotated by a motor and generates a linear motion of the operation rod 136, a linear motor device, a pneumatic or hydraulic cylinder, or the like. An actuator 135 is provided at the base frame 103, and a distal end portion of an operation lever 136 is rotatably connected to a lever attachment piece 134 formed below the rotating member 130. Therefore, as shown in fig. 8A to 8C, when the operation lever 136 is contracted and moved forward, the rotation member 130 rotates downward about the first rotation shaft 131, so that the backrest portion 110 is inclined rearward of the chair, and when the operation lever 136 is extended and moved rearward, the rotation member 130 rotates upward, so that the backrest portion 110 is returned to the initial upright state.

On the other hand, the reclining chair may further include, at the front end portion of the swivel seat portion 120: a lower leg part lifter for lifting the lower leg part of the user; and an elevator driving unit which provides a rotational force to the lower leg elevator.

Referring to fig. 5 and 9 to 10B, the lower leg portion lifter includes: an elevator bracket 141, both lower ends of which are rotatably provided at the front end of the side panel 122 of the rotary seat part 120 around an elevator hinge shaft 141 a; an elevator frame 142 coupled to both upper ends of the elevator frame 141 and rotating together with the elevator frame 141; and a slide plate 143 that is unfolded or folded while sliding with respect to the elevator frame 142. When the elevator frame 142 is rotated to the upper side (forward), the slide plate 143 is slid and unfolded by the elevator driving unit to support the user's lower leg and foot, and when the elevator frame 142 is rotated to the lower side (backward), the slide plate 143 is slid and folded by the elevator driving unit.

On both side portions of the elevator frame 142, curved elevator guide holes 142a are formed along a rotation locus, and the side panel 122 of the rotary seat portion 120 is provided with elevator guide pins 142b which are inserted inside the elevator guide holes 142a while guiding the rotational movement of the elevator frame 142.

Guide rail portions 142c for guiding both side portions of the slide plate 143 are formed on both side portions of the elevator frame 142.

The elevator driving unit includes: an elevator actuator 145 having an elevator operating lever 145a, provided on the base frame 103, connected to an elevator support 141 of the lower leg elevator, and configured to extend and contract in the front-rear direction of the chair and rotate the elevator support 141; a plurality of links 146 rotatably connected to an intermediate portion of the elevator frame 142 and a front end portion of the slide plate 143, transmitting a force of pushing or pulling the slide plate 143 with respect to the elevator frame 142; and a rod end bearing 148 having one end connected to a front end portion of the base frame 103 and the other end connected to a link pin 147 of the connection link 146, and applying a force to the link pin 147 in a front-rear direction of the elevator frame 142 according to rotation of the elevator frame 142.

Therefore, when the lifter lever 145a of the lifter actuator 145 is retracted, the lifter bracket 141 rotates rearward about the lifter hinge shaft 141a, and the lifter bracket 142 rotates forward and expands. At this time, since the rod-end bearing 148 pushes the link pin 147, the link 146 is pushed forward, and the slide plate 143 slides forward with respect to the elevator frame 142 and expands.

In contrast, when the lifter lever 145a of the lifter actuator 145 is extended, the lifter bracket 141 rotates forward about the lifter hinge shaft 141a, and the lifter bracket 142 rotates rearward and is folded into the initial state. At this time, since the rod-end bearing 128 pulls the link pin 147, the link 146 is pulled rearward, and the slide plate 143 slides rearward with respect to the elevator frame 142 and is folded.

On the other hand, fig. 11 to 12B show another embodiment of the reclining chair, which differs from the above-described embodiment in the structure of the guide unit that guides the rotational movement of the rotary seat portion 120 with respect to the base frame 103 of the main body portion 100 while supporting the rotary seat portion 120 with respect to the base frame 103.

In this embodiment, the guide unit includes: a guide hole 105 formed at a side surface of the base frame 103 to be inclined in an up-down direction; the guide pin 106 is provided at one side of the rotary seat portion 120 to be inserted into the guide hole 105, and slides along the guide hole 105 when the rotary seat portion 120 is rotated by the driving unit.

Therefore, when the rotary seat portion 120 is linked with the rotary member 130 and rotated, the guide pin 106 of the rotary seat portion 120 moves along the guide hole 105 of the base frame 103 while guiding the rotational movement of the rotary seat portion 120, and in the rotated state, the accidental descent of the rotary seat portion 120 can be prevented by supporting the weight of the user acting in the vertical direction.

The reclining chair as described above has the following advantages: when the angle of the backrest part 110 is adjusted, the angle of the rotary seat part 120 supporting the buttocks and the thighs is adjusted simultaneously as it is interlocked with the rotational movement of the rotating member 130, so that no gap is generated between the armrest part 115 and the rotary seat part 120 provided in front of both sides of the backrest part 110, and the leg position is increased compared to before, so that the comfort can be improved.

The present invention has been described in detail with reference to the embodiments, but it is understood that those skilled in the art to which the present invention pertains may make various substitutions, additions and modifications without departing from the scope of the technical idea as described above, and it is understood that the embodiments modified as above also fall within the scope of the present invention as defined in the appended claims.
