[0013] The folding mattress 1 according to this embodiment.
00 is suitably used for a folding bed as shown in FIG. 3 developed by the inventor of the present application.

The folding bed shown in FIG. 3 comprises a frame base 1, an upper body movable frame 2, a lower body movable frame 3, an upper body supporting leg 4 for supporting the upper body movable frame 2, and a lower body. The upper body-side movable frame 2 includes a lower body-side support leg 5 that supports the side movable frame 3, and a headboard 6 that is provided at an end of the upper body-side movable frame 2 on the head side. At the lower end of the frame base 1, two left and right free casters 11 are provided. In the folding mattress 100 according to the present invention, the upper body side mattress 110 extends from the intermediate position of the frame base 1 to the upper body side movable frame 2, and the lower body side mattress 120 is mounted on the frame base 1.
From the middle position to the lower body side movable frame 3.

The upper body-side movable frame 2 has one end rotatably connected to an upper body-side end above the frame base 1 via a connecting shaft 21. The upper body-side support leg 4 is swingably mounted on a bracket 22 protruding from the rear side of the upper body-side movable frame 2 via a connection shaft 23.

The lower body-side movable frame 3 is relatively shorter than the upper body-side movable frame 2 as will be described later. It is rotatably connected through the. The lower body side supporting leg 5 is attached to a bracket 32 projecting from the rear side of the lower body side movable frame 3 by a connecting shaft 33.
It is provided so as to be able to swing through.

The connection between the frame base 1 and the upper body side movable frame 2 and the lower body side movable frame 3 by the connecting shafts 21 and 31 is slightly larger than the sum of the thicknesses of the upper body side mattress 110 and the lower body side mattress 120. Separated from each other by distance.

In response to the difference in the length of the upper body side movable frame 2 and the lower body side movable frame 3, the upper body side mattress 110 is longer than the lower body side mattress 120, and when the mattresses 110 are horizontally opened from each other, FIG. As shown, the boundary A between the mattresses 110 and 120 is located on the lower body side relative to the buttocks B of the human body. Further, the upper body side mattress 110 is laid from an intermediate position of the frame base 1 to the upper body side movable frame 2,
Since the lower body side mattress 120 is laid from the intermediate position of the frame base 1 to the lower body side movable frame 3, both mattresses 110 and 120 are respectively more frame base than the upper body side and the lower body side movable frame 2, 3. The length of the base 1 is about half as long.
As a specific example, for example, the length of the upper body side mattress 110 is about 1120 mm, and the length of the lower body side mattress 120 is about 830 mm.

Connecting rods 41 and 51 are connected between the upper and lower body supporting legs 4 and 5 and the frame base 1, respectively. More specifically, these connecting rods 41 and 51 have one ends respectively connected to projections 4a and 5a protruding from side surfaces of the supporting legs 4 and 5 in the folding and swinging direction at intermediate portions in the longitudinal direction of the support legs 4 and 5, and connecting shafts 42 and 51 respectively. 52
And the other end is rotatably connected to the frame base 1 at a position below the joint with the movable frame 2.3 via the connection shafts 43 and 53. .

Upper and lower body movable frames 2 and 3
In a state in which the upper and lower body side supporting legs 4 and 5 are tilted by the upper and lower body side connecting rods 41 and 51, the swinging ends of the upper and lower body side supporting legs 4 and 5 are freely casters 1.
The legs are held in a state where the legs are opened so as to be substantially the same height as the lower ends of the legs 1 and 11. Further, as shown by a two-dot chain line in FIG. 3, in a state where the movable frames 2 and 3 are erected substantially vertically, the support legs 4 and 5 are folded to the rear side of the movable frames 2 and 3 and The joints between the supporting legs 4 and 5 by the connecting shafts 42 and 52 and the connecting rods 41 and 51 on the upper and lower body sides are connected to the connecting shafts 43 and 53 and the connecting shaft 2.
The length of the supporting legs 4, 5 and the connecting rods 41, 51, and the mounting of each of the connecting shafts by the brackets 22, 32, the protruding portions 4a, 5a, etc. so as to be completely open between the connecting shafts 3 and 33. The position is set properly.

The head board 6 has a pair of left and right arms 61 extending from both ends in the width direction (the direction orthogonal to the plane of the drawing).
The base ends of the arms 61 are connected to connecting shafts 62, respectively.
Is connected rotatably to the vicinity of the head-side end of the upper body-side movable frame 2. The arm 61 is formed in a substantially L-shaped bent shape.
The base board 61 on the second side is supported substantially horizontally on a stopper 24 formed at the end of the upper body side movable frame 2, so that the head board 6 is appropriately inclined with respect to the upper body side movable frame 2. It will be in the state of standing upright.

When the base 61a of the arm 61 is supported on the stopper 24, the lower end edge 6a of the head board 6 is positioned lower than the upper surface of the upper body side mattress 110, and the head board 6 is shifted from the upper body side mattress 110. I'm stopping. Then, from this state, the arrow R in FIG.
As shown by 1, when the head board 6 is rotated by a predetermined angle about the connection shaft 62, the base 6 of the arm 61 is rotated.
Since the head board 6 is lifted by the angular displacement of 1a as shown by the dashed line in FIG.
The upper body side mattress 110 is movable in the longitudinal direction.

At the swinging end of the lower body side movable frame 3,
A foot board 34 for preventing the lower body side mattress 120 from slipping is provided.
It can be turned down as shown by arrow R2 in FIG. The movable frames 2 and 3 are provided with latches 25 and 35 on the opposite side surfaces, respectively, so that the movable frames 2 and 3 stand in the folded state shown by the two-dot chain line in FIG. By being hooked in a state of being obliquely bridged, it can be restrained in the folded state.

The folding bed having the above structure is shown in FIG.
By raising the upper body-side movable frame 2 and the lower body-side movable frame 3 from a horizontally open and usable position shown by a solid line in FIG. 5, the folding can be performed as shown by a two-dot chain line.

The upright motion of the upper body side movable frame 2 is performed by using the head board 6 as a handle, whereby the head board 6 is displaced in the direction of arrow R1 relative to the upper body side movable frame 2. The trajectory of the upright motion of the upper body side movable frame 2 is centered on the connecting shaft 21, whereas the trajectory of the upright motion of the upper body side mattress 110 is, as shown in FIG. Centering on the side edges 111a, 121a of the connecting portion with the lower body side mattress 120 by the connecting bands 130, 140 of FIG.
In the process of the standing operation, the upper body side mattress 110 is relatively displaced so as to protrude outward (upward) from the space between the upper body side movable frame 2 and the headboard 6 due to the difference in the trajectories. Also, in the process of this standing motion,
Since the upper body side mattress 110 is not deformed by compression, no resistance is generated by such deformation.

In the process of erecting the upper body side movable frame 2, the trajectory C of the swinging end of the upper body side connecting rod 41 and the connecting shaft 2 serving as a fulcrum of the upper body side support leg 4.
3, the upper body-side connecting rod 41 and the upper body-side supporting leg 4 jointly operate with each other via a connecting shaft 42, whereby the upper body-side supporting leg 4 is moved to the back of the upper body-side movable frame 2. Folded towards

The same applies to the raising operation of the lower body side movable frame 3, and the lower body side mattress 120, which is to be raised, is protruded outward (upward) from the swinging end of the lower body side movable frame 3. Relative displacement. In the process, due to the difference between the trajectory E of the swinging end of the lower body side connecting rod 51 and the trajectory F of the connecting shaft 33 which is the fulcrum of the lower body side support leg 5, these lower body side connecting rod 51 and lower body side The support legs 5 jointly operate with each other via a connection shaft 52, and the lower body side support legs 5
Is folded toward the back of the lower body-side movable frame 3.

In a folded state in which the movable frames 2 and 3 stand almost vertically, as shown by a two-dot chain line in FIG.
The joints of the supporting legs 4 and 5 and the connecting rods 41 and 51 by the connecting shafts 42 and 52 are completely opened. The connecting shafts 42 and 52 of the joints are provided on the projections 4a and 5a protruding from the inner surfaces of the support legs 4 and 5, and in this state, the connecting shafts 43 and 53 and the connecting shaft 23 are provided. , 33 and closer to the movable frames 2 and 3 than the straight line connecting them, and exerts a braking function by a so-called deadlock action. For this reason, the movable frames 2 and 3 are maintained in the vertically upright folded state.

Therefore, in the folding operation of the folding bed, it is not necessary to raise the upper body side and lower body side movable frames 2 and 3 at the same time. That is, one of the movable frames is raised and the deadlock action of the joints causes After being held upright, the other movable frame can be erected. For this reason,
For example, even a female employee can easily fold it. After the folding, the movable frames 2 and 3 can be restrained in an upright state by the latches 25 and 35.

Further, for example, when the mattress is a single material, the movable frames 2 and 3 by the connecting shafts 21 and 31 are used in order to prevent an excessive load on the mattress at the time of folding.
It is necessary to increase the distance between the connecting portions (the length of the frame base 1) to some extent. However, by using the folding mattress 100 of the present invention, the distance between the upper and lower body side movable frames 2 and 3 that are raised can be increased. Since the distance may be slightly larger than the sum of the thicknesses of the upper body side and lower body side mattresses 110 and 120, the horizontal storage space in the folded state can be made smaller than before.

Next, in order to lower the upper and lower body side movable frames 2 and 3 from the above-mentioned folded state to a horizontally open and usable state, first release the latches of the latches 25 and 35. Then, the support legs 4 and 5 are pulled in the direction in which the movable frames 2 and 3 are pulled down. In this way, the joints between the supporting legs 4 and 5 and the connecting rods 41 and 51 by the connecting shafts 42 and 52 are bent outward, whereby the deadlock action is released and the supporting legs 4 and 5 are released. , The movable frames 2 and 3 are pulled in the pulling-down direction, and the movable frames 2 and 3 naturally fall down while the supporting rods 4 and 5 are opened by the connecting rods 41 and 51.

The folding mattress 100 according to the present invention
Is the upper body side mattress 110 and the lower body side mattress 1
Since 20 is a separate body and is connected by the connecting bands 130 and 140, no elastic opening force is generated at the connecting portion. Therefore, the movable frames 2 and 3 do not suddenly fall down due to the opening force.

In the use state in which the upper and lower movable frames 2 and 3 are opened horizontally by tilting the upper and lower body side movable frames 2 and 3, as shown in FIG. 4, the difference in length between the upper body side mattress 110 and the lower body side mattress 120 causes Since the boundary A is located on the lower body side relative to the buttocks B of the lying human body, the boundary A does not impair sleeping comfort.

As shown in FIG. 2, the folding mattress 100 can be folded in both the P and P ′ directions and the opposite Q and Q ′ directions.
2 and the surfaces 113 and 123 may be laid so as to be the upper surface. Therefore, when one side is damaged to some extent by repeated use, the mattress can be used upside down, and the life of the mattress can be improved.

The present invention is not limited to the illustrated embodiment. For example, a plurality of first connectors 130 and second connectors 140 are alternately arranged in the width direction of the mattress. Is also good. Further, the first and second connectors 130 and 140 are connected to both mattresses 110 and 120.
Therefore, it is not necessary to sew at the positions of the side edges 111a, 111b, 121a, 121b of the upper and lower body side mattresses 110, 120, and only one surface in the thickness direction is required. 112,122
Alternatively, sewing may be performed on the other surfaces 113 and 123 in the thickness direction.

[0036]

As described above, according to the folding mattress of the present invention, the upper body side mattress and the lower body side mattress are connected by using the first connecting body and the second connecting body as hinges. Because it is possible to fold both sides in the thickness direction, when laying on a folding bed, there is no restriction on which of the two sides in the thickness direction is to be the top side, so the mattress life is extended by being able to use both sides Can be improved.
