Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a chair for resting that can be used for resting, reading, etc., and can freely change the optimal inclination angle of the backrest.

(Prior Art) Conventionally, this type of resting chair with a backrest whose inclination angle can be changed has been constructed by providing a plurality of grooves for changing the inclination angle and manually changing the inclination angle in stages, or by using a spring. There are chairs that are configured to change the inclination angle using a lever mechanism. Additionally, an ottoman (footrest) is prepared separately and used in combination.

(Problems to be Solved by the Invention) However, the above-mentioned conventional manual type with grooves has the inconvenience of having to stand up and operate it each time to change the inclination angle of the backrest.

Furthermore, those equipped with springs and levers require a lever operation to change the inclination angle of the backrest, and the mechanism is complicated and expensive. Furthermore, there are other problems such as the need to prepare a separate ottoman for resting the feet.

(Means for solving the problem) The present invention was made to solve the above problem, and the backrest frame 4 is rotatably attached to the rear of the pair of inverted U-shaped leg frames 1, 1. When the pivot is attached,
The leg frames 1, 1 are rotatably pivoted to the front through the swing frame 7, and the rear end of the footrest frame 9 is rotatably pivoted to the lower end of the backrest frame 4. 4
A bendable seat member 12 is attached from the upper end to the rear end of the footrest via the rotating horizontal frame member 7B installed between the swinging frames 7, and the seat member 12 is attached so that the entire body can be placed on the chair and the back force can be reduced. To provide a chair in which the inclination angle of the backrest can be freely changed by adjusting the angle of inclination of the backrest.

(Example) Hereinafter, the present invention will be explained in detail based on the example shown in FIGS. 1 to 4. In addition, FIG. 1 is an overall perspective view of the resting chair according to the present invention, FIG. 2 is an enlarged cross-sectional view taken along the - line in FIG. 1, FIG. 3 is an enlarged cross-sectional view of the connecting part, and FIG. It is an explanatory view of the operating state of the invention.

In the above drawing, 1 is an inverted U-shaped leg frame connected at an upper part 1A, and the front and rear legs 1B, 1C are connected at the lower part by a connecting member 1D,
An armrest 1E is formed above the upper part 1A, and a stand 2 is removably attached to the outer surface of the upper part 1A.

The pair of left and right leg frames 1, 1 are the front leg parts 1B, 1B.
The space between them is connected by a connecting member 3A at the lower part thereof, and the rear leg parts 1C and 1C are connected by connecting members 3B and 3C at the center and lower part thereof, respectively. are connected by a connecting member 3D.

Reference numeral 4 denotes a backrest frame, which is composed of a horizontal frame member 4A at the upper end and vertical frame members 4B, 4B on the left and right sides, and the center part of the vertical frame members 4B, 4B is attached to the upper end of the rear leg 1C via a spacer 5. The vertical frame members 4B, 4B are pivotally connected to each other so as to be rotatable, and the lower ends 4C of the vertical frame members 4B extend to the vicinity of the lower ends of the rear legs 1C.

7 is a swing frame, and left and right vertical frame members 7A, 7A,
It is composed of a rotatable horizontal frame member 7B and a horizontal frame member 7C, and the upper ends of the vertical frame members 7A, 7A are rotatable by bolts 8 via spacers 5 on the upper parts of the front legs 1B, 1B. The lower ends 7D of the vertical frame members 7A, 7A extend to near the lower end of the front leg portion 1B and above the connecting member 3A.

Reference numeral 9 denotes a footrest frame, and the front and rear long frame members 9A, 9A are arranged horizontally at the lower part of both the front and rear leg parts 1B, 1C and above the connecting member 3A. The central part of the bolt 10 is connected to the lower end 7D of the vertical frame members 7A, 7A of the swing frame 7, and the rear end thereof is connected to the lower end 4C of the vertical frame members 4B, 4B of the backrest frame 4 via the spacer 5, respectively. , 11 so as to be rotatable, and the front leg portion 1B
A footrest portion 9B is formed in the portion that protrudes further forward.

12 is a sheet member, and a large number of bar-shaped pieces 12 are arranged in parallel.
A, 12A, and belts 12B, 12B connecting these from the back side, the upper end 12C of which is fixed to the horizontal frame member 4A of the backrest frame 4, and the other end is connected to the rotation of the swing frame 7. When stretched over the horizontal frame member 7B in a slack state, the lower end 12D is fixed to the rear end of the footrest 9B. In the drawings, reference numerals 13A and 13B indicate cushioning materials attached to the stopper portions, respectively, when the backrest frame is in its normal state when it is upright, and when it is in a state where the backrest frame is tilted backwards.

(Operation of the embodiment) The operation of the embodiment of the present invention will be explained based on FIGS. 2 to 4.

In the normal state, that is, in the state where the backrest frame 4 is upright, the seat member 12 is suspended with slack as shown in FIG. It transforms into a shape that follows its body shape.

If the user puts a little force on his back and leans back from this state, the backrest frame 4 will fall back using the pivot portion 6 as a fulcrum, as shown in FIG. In conjunction with this operation, the footrest frame 9 suspended by the backrest frame 4 and the swinging frame 7 moves through the pivot parts 8, 10,
11 as an axis and moves from the position shown by the solid line to the upper position shown by the broken line, and becomes in the state of an easy chair.
In this case, the seat member 12 moves toward the seat and back with the rotating horizontal frame member 7B of the swing frame 7 as a boundary, but this movement is caused by the rotation of the rotating horizontal frame member 7B over which the seat member 12 is stretched. Moves more smoothly.

Further, when the back is raised, the backrest frame 4 rises and moves in the opposite manner to the above, returning to the state shown by the solid line in FIGS. 2 and 4. In addition, when the backrest frame 4 is in the upright position, it comes into contact with the cushioning material 13A of the stopper and stops.
Furthermore, by adjusting the force applied to the backrest frame 4, the backrest frame 4 can be continuously tilted steplessly and maintained at that position until it comes into contact with the cushioning material 13B of the stopper and stops.

(Effects of the present invention) As described above, the present invention has a backrest frame rotatably pivoted to the rear of a pair of inverted U-shaped leg frames, and a swing frame is attached to the front of the leg frames. The rear end of the footrest frame, which is rotatably pivoted through the frame, is rotatably pivoted to the lower end of the backrest frame, and the rotating horizontal frame member is attached from the top of the backrest frame to between the swinging frame. Since a bendable sheet member is attached to the rear end of the footrest, by adjusting the force on the back, the angle of the backrest frame 4, that is, the angle of the backrest, can be adjusted steplessly to any desired position. Can be changed continuously. In addition, since the seat member 17 is suspended with slack, it has a shape that adapts to the body shape of the person sitting on the seat, making it comfortable to sit on, and the seat member 12 smoothly follows changes in the angle of the backrest. and has good operability. Furthermore, since the footrests are connected, there are other benefits such as there is no need to separately place an ottoman (footrest device) or the like.
