Description

[Detailed Description of the Invention] This invention relates to a bed device in which a headboard body is erected at one longitudinal end of a base.

Generally, a bed device is formed by placing a mattress on the upper surface of a base and having a headboard erected at one longitudinal end of the base. The headboard body has functions such as preventing pillows from slipping off and drafts from hitting the user's head. Furthermore, when the user takes a posture with his/her upper body raised up to read, eat, etc. on the mattress, the user leans against the headboard body in order to comfortably maintain that posture.

By the way, when the user takes a posture with the upper body upright, it is more comfortable for the user to have the upper body fall backwards to some extent. However, since the headboard body is usually vertically erected, the user has to raise his or her upper body almost vertically in order to lean on it, which tends to cause fatigue.

This invention was made based on the above circumstances, and its purpose is to provide a bed device that allows the user to lean on the headboard body in a comfortable posture.

An embodiment of this invention will be described below with reference to FIGS. 1 to 5. The bed device shown in FIG. 1 includes a base 1. The bed device shown in FIG. A headboard body 2, which will be described later, is provided at one longitudinal end of the base body 1, and a footboard body 3 is provided at the other end. Further, a pinerest 4 is placed on the upper surface of the base 1.

The headboard body 2 is formed as shown in FIGS. 2 and 3. That is, the headboard body 2 has a lower rod 5 horizontally provided at its lower end, which is a rectangular pipe having a length that is approximately the same as the width of the base body 1. Vertical rods 6 (only one of which is shown) are erected at both ends of the lower rod 5, and both ends of an upper rod 7 are fixed to the upper ends of these vertical rods 6. A mounting hole 8 is bored at the lower end of the vertical rod 6. Further, at both ends of the lower rod 5 and the upper rod 7, there are mounting rods 9 (only one shown), which are longer than the height of the upper surface of the pinerest 4 placed on the base 1, at the lower end and the middle. It is fixed vertically. Both ends of a movable rod 11 bent into an L-shape are connected to the upper ends of these mounting rods 9 via a hinge mechanism 10. That is, as shown in FIGS. 4 and 5, the hinge mechanism 10 includes a first connecting plate 12 whose one end is fixed to the upper end of the mounting rod 9, and a first connecting plate 12 whose one end is bent from the movable rod 11. The second connecting plate 13 is fixed to one end thereof, and the other ends of the first and second connecting plates 12, 13 are each fixed to a support shaft 14.
It is formed from an intermediate plate 15 which is pivotally connected by. Both ends of this intermediate plate 15 are formed into a first disc part 16 and a second disc part 17, respectively. A first notch 18 is formed in the circumference of the first disc part 16 to which the first connecting plate 12 is connected, in a range of about 75 degrees in the circumferential direction, and a first notch 18 is formed in the peripheral part of the second disc part 17. A second notch 19 is formed in a range of about 90 degrees in the circumferential direction. Further, a first engagement shaft 20 that engages with the first notch 18 is protruded from the first connecting plate 12 , and a first engagement shaft 20 that engages with the second notch 19 is provided on the second connecting plate 13 . A second engagement shaft 21 is provided in a protruding manner. 1st
The engagement shaft 20 contacts one end of the first notch 18 when the intermediate plate 15 is aligned with the first connecting plate 12, and the second engagement shaft 21 contacts the intermediate plate 15. As shown in FIG. 4, the second connecting plate 13 is brought into contact with one end of the second notch 19 in a slightly tilted counterclockwise direction. Therefore, in the intermediate plate 15 and the second connecting plate 13, the first and second engagement shafts 20 and 21 are connected to the first and second notches 18 and 19, as shown by the chain lines in the figure. It can be rotated clockwise as shown by the arrow (this direction is the front direction) until it hits the edge. In other words, the intermediate plate 15
The second connecting plate 13 rotates approximately 90 degrees relative to the intermediate plate 15. The sum of these two rotation angles is approximately 165 degrees, so
When the intermediate plate 15 and the second connecting plate 13 are rotated in the front direction, the second connecting plate 13 connects with the first connecting plate 1.
It is held at an angle of about 15 degrees relative to 2.

As shown in FIG.
A large number of elastic bands 22, both ends of which are connected by connecting strings 21, are stretched in a grid pattern. Further, on the back surface of the upper frame, fabrics 23 are stretched between the upper ends of the mounting rods 9 and between the bent ends of the movable rods 11, as shown in FIG. Furthermore, an elastic material 24 such as urethane foam is bonded to the entire back surface of the entire frame formed by the lower rod 5, the mounting rod 9, and the movable rod 11. Further, the entire frame is covered with an exterior body 25 sewn into a bag shape. The exterior body 25 is made of a material that has cushioning properties by interposing cotton, urethane foam, or the like between a pair of fabrics, although details are not shown. In addition, a through hole 26 is formed in the exterior body 25 and corresponds to the mounting hole 8 bored in the vertical rod 6. The headboard body 2 is connected and fixed to the base body 1 with its front surface facing the mattress 4 side by screws (not shown) passed through the mounting holes 8. Therefore, with the headboard body 2 formed in this manner, the entire length of the movable rod 11, that is, the upper end portion in the width direction forms a bending portion 27 that can be bent toward the mattress 4 side. .

According to the bed device configured in this way, when the user reads, eats, etc.
When raising the upper body on the floor, bend the bent portion 27 of the headboard body 2 as shown by the chain line in FIG. Then, due to the structure of the hinge mechanism 10, this bent portion 27 is approximately separated from other parts of the headboard body 2.
It is held in an inclined position at an altitude of 15 degrees. Therefore, by leaning on the bending portion 27, the user can take a comfortable posture in which the upper body of the user falls backward. Furthermore, since the user leans on the back side of the bending section 27, that is, the side on which the elastic material 24 is provided, the elastic material 24 and the band 2
A good feel can be obtained due to the cushioning properties of item 2.

Note that this invention is not limited to the above-mentioned example,
For example, if the bed device is double size,
As shown in FIG. 6, the upper end portion of the headboard body 2 is divided approximately at the center in the width direction to form two bent portions 2.
7 may be formed so that only one of the two users using the bed device can lean on one of the bending portions 27.

Further, in the above embodiment, when the bending portion 27 is bent, it is held at an inclined angle by the hinge mechanism 10. However, when the bending portion 27 is bent, the hinge mechanism 10 Depending on the thickness of the exterior body 25 interposed between the first connecting plate 12 and the second connecting plate 13, the second connecting plate 13, that is, the bent portion 27 can be held in an inclined state. That is, if the bending portion 27 has a bendable structure, it will inevitably be in an inclined state when it is bent.

As described above, this invention connects the mounting frame and the movable frame of the headboard body to both ends of the intermediate plate of the hinge mechanism using a first connecting plate whose one end is rotatably connected at an angle within a predetermined range. and the other end of the second connecting plate, and the mounting frame and the movable frame are covered with an exterior body. Therefore, since the movable frame can be bent and held at a predetermined angle,
When the user takes a posture with the upper body raised on the pinerest, the user can take a comfortable posture by leaning on the movable frame. Further, since the hinge mechanism is composed of an intermediate plate and first and second connecting plates each having one end connected to both ends of the intermediate plate so as to be rotatable within a predetermined angle range, the hinge mechanism constituting the headboard body Even if the mounting frame and movable frame connected by a mechanism are covered with an exterior body, the intermediate plate has a predetermined length so that it is sandwiched between the movable frame and the mounting frame. The movable frame can be bent together with the exterior body without the exterior body getting in the way. In other words, since the hinge mechanism can be housed within the exterior body of the headboard body so as not to be exposed to the outside, it has a very good appearance.
