  Patent Document 1 below proposes a folding bed having a bed frame including a first frame and a second frame that are foldably connected. Such a folding bed can be transformed into a folded state in which the first frame and the second frame are folded in an inverted V shape.

  The folding bed includes a mat on which a user's body is placed. The mat is divided into a first mat disposed on the first frame and a second mat disposed on the second frame.

JP 2005-124651 A

  In the above folding bed, since the mat is divided into an upper body and a lower body, there is a problem in that the vicinity of the user's waist is located on the edge of the mat and the sleeping comfort is poor.

  The present invention has been devised in view of the above circumstances, and has as its main object to provide a folding bed that can realize a comfortable sleeping comfort.

  The present invention has a bed frame including a first frame and a second frame that are foldably connected, and in a side view of the bed, the bed frame is substantially horizontal, the first frame, and the second frame. A folding bed that is deformable into a folded state in which the frame is folded in an inverted V shape, and is arranged on the bed frame and continuous without being divided from the first frame to the second frame A seamless mat that extends, first fixing means for fixing one end of the seamless mat to the first frame, and the other end of the seamless mat slid to the second frame in the bed length direction. And second fixing means for fixing in a possible manner.

  In the folding bed according to the present invention, it is preferable that the second fixing means includes an elastic band for pressing the seamless mat against the second frame.

  In the folding bed according to the present invention, it is preferable that the elastic band extends in the bed width direction, and both ends thereof are respectively fixed to the seamless mat and are wound around the second frame.

  The folding bed according to the present invention preferably further includes biasing means for biasing the other end side of the seamless mat toward the outer edge side of the second frame in the bed length direction.

  In the folding bed according to the present invention, it is preferable that the first fixing means is a cover that covers the seamless mat, and the cover is fixed to the first frame.

  The folding bed of the present invention includes a seamless mat that is arranged on a bed frame and extends continuously without being divided from the first frame to the second frame. In the seamless mat, the mat is not interrupted at the middle portion in the length direction of the bed. Therefore, for example, the user does not feel uncomfortable around his / her waist and can obtain a comfortable sleeping comfort. In addition, the seamless mat can distribute the user's load over the entire mat. For this reason, in the seamless mat, the partial deformation due to the load is suppressed to be small.

  On the other hand, when the seamless mat is completely fixed to the first frame and the second frame, when the bed is folded in an inverted V shape, a large distortion occurs in the seamless mat at the top of the inverted V shape. Therefore, when the folding bed is repeatedly deformed between the horizontal state and the folded state, there is a possibility that the intermediate portion of the seamless mat may be sagged or damaged. Therefore, in the present invention, the first fixing means for fixing one end of the seamless mat to the first frame and the other end of the seamless mat are fixed to the second frame so as to be slidable in the bed length direction. Second fixing means. Thereby, when the bed is deformed into a folded state, the other end side of the seamless mat can be slid to one end side along the second frame so as to relieve distortion at the intermediate portion. . For this reason, in the folding bed of this invention, the distortion which arises in the intermediate part of the seamless mat transformed into the folding state can be reduced, and a sag and damage of a seamless mat can be prevented over a long period of time, and durability can be improved.

It is a perspective view of the folding bed of the embodiment of the present invention. It is a side view of the folding bed of FIG. It is a side view of the folding bed of a folded state. It is an expansion perspective view near the 2nd frame.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a folding bed (hereinafter simply referred to as “bed”) 1 of the present embodiment, and FIG. 2 is a side view thereof.

  As shown in FIG. 1, the bed 1 includes, for example, a bed frame 2 made of a metal material and a mat 3 arranged on the bed frame 2. Hereinafter, in this embodiment, regarding the direction of the bed 1, the bed length direction is represented by X, the bed width direction is represented by Y, and the bed height direction is represented by Z.

  The bed frame 2 includes a known folding mechanism including a first frame 4, a second frame 5, and a connecting frame 6 that couples them together so as to be bent. The first frame 4 of the present embodiment supports, for example, the upper body side of the user. The second frame 5 of the present embodiment supports the lower body side of the user, for example. However, the first frame 4 may support the lower body side of the user, and the second frame 5 may support the lower body side of the user.

  For example, the first frame 4 and the second frame 5 have the same length. As a result, the connecting frame 6 is located at a substantially intermediate portion C in the length direction X of the bed 1. Each of the first frame 4 and the second frame 5 is provided with leg portions 7 on both sides in the bed width direction Y, for example. Each leg 7 is pin-coupled to each frame 4 and 5 so as to be rotatable.

  For example, the connecting frame 6 is rotatably connected to the first frame 4 and the second frame 5 by a pin extending in the bed width direction Y. The connecting frame 6 includes legs 8 extending in the bed height direction Z. The leg portion 8 of the present embodiment is provided so as to be able to contact the floor surface in a state where the bed 1 is horizontal.

  The bed 1 described above has a horizontal state in which the bed frame 2 is substantially horizontal, and a folded state in which the first frame 4 and the second frame 5 are folded in a substantially inverted V shape as shown in FIG. It can be deformed.

  As a preferable aspect, the bed 1 of the present embodiment includes a reclining mechanism as shown in FIG. Although the details are not shown in the first frame 4, only the head side is lifted in the initial reclining state as in the bed of the above-mentioned Patent Document 1, for example, there is a known reclining mechanism that can provide a pillow to the user. Is provided. In this case, the first frame 4 can include a base frame 9 that is substantially rectangular in plan view, a tilting unit 10 that is placed on the base frame 9, and a drive unit 11 that tilts the tilting unit 10.

  The tilting part 10 includes a tilting part 10a on the head side and a tilting part 10b on the upper body side that is tilted behind the tilting part 10a on the head side. In such a reclining mechanism, after the tilt portion 10a on the head side is lifted, the tilt portion 10b on the upper body side is also tilted upward together with the tilt portion 10a.

  Similarly, the second frame 5 of the present embodiment is also provided with a known reclining mechanism that can be bent into a mountain shape in a side view, as shown in the bed of Patent Document 1, although details are not shown. In this case, the second frame 5 can include a base frame 13 that is substantially rectangular in plan view, a tilting portion 14 that is placed on the base frame 13, and drive means 15 that tilts the tilting portion 14.

  The tilting portion 14 includes a tilting portion 14a inside the bed in the length direction X, and a tilting portion 14b outside the bed in the length direction X that is rotatably connected to the tilting portion 14a.

  The mat 3 of this embodiment includes a seamless mat 20 disposed on the bed frame 2. The seamless mat 20 extends continuously without being divided from the first frame 4 to the second frame 5. Such a seamless mat 20 does not break the mat at the intermediate portion C in the bed length direction X. For this reason, for example, the user does not feel a sense of incongruity near the waist and can obtain a comfortable sleeping comfort. Moreover, the seamless mat 20 can disperse the user's load throughout. For this reason, as for the seamless mat 20, the partial deformation | transformation by a load is suppressed small. Such a seamless mat 20 is desirably formed of a sponge material using, for example, urethane foam or polyethylene foam.

  When the seamless mat 20 is completely fixed to the bed frame 2, as shown in FIG. 3, when the bed 1 is deformed into a folded state, a large distortion tends to occur at the top of the inverted V shape. . For this reason, when the bed 1 is repeatedly deformed into a horizontal state and a folded state, the intermediate portion C of the seamless mat 20 may be sagged or damaged.

  The bed 1 according to the present embodiment includes a first fixing means 18 for fixing one end S1 side of the seamless mat 20 to the first frame 4, and the other end S2 side of the seamless mat 20 on the second frame 5, and the bed length. And a second fixing means 19 for slidably fixing in the direction X.

  The seamless mat 20 of the present embodiment has one end S1 in the bed length direction X such that when the bed 1 is deformed into the folded state, the other end S2 side of the seamless mat 20 is relieved of distortion at the intermediate portion C. Slide deformed to the side. Accordingly, in the bed 1 of the present embodiment, the intermediate portion C of the seamless mat 20 is shifted from the inverted V-shaped top portion, and distortion generated in the intermediate portion C is reduced, so that the sag in the intermediate portion C of the seamless mat 20 is reduced. Damage can be prevented over a long period of time, and durability can be improved.

  The first fixing means 18 is, for example, a cover 22 formed in a bag shape, and preferably covers the seamless mat 20. The cover 22 of this embodiment is fixed to the first frame 4. More specifically, for example, the cover 22 preferably covers the first frame 4 (in the present embodiment, the tilting portion 10) on which the seamless mat 20 is disposed together with the seamless mat 20. Thereby, the seamless mat 20 is fixed to the first frame 4 through the cover 22 and is integrated with the first frame 4 in both the horizontal state and the folded state. The cover 22 is appropriately formed with a fastener or the like for removing the seamless mat 20.

  When the first frame 4 does not include a reclining mechanism, the cover 22 desirably covers at least a part of the base frame 9 of the first frame 4 together with the seamless mat 20, for example. Such a cover 22 can also fix the seamless mat 20 and the first frame 4 together. In addition, the first fixing means 18 of another aspect includes the seamless mat 20 and the first frame 4, for example, by providing an engagement portion that can be engaged with each other on the lower surface of the seamless mat 20 and the first frame 4. The structure which can be fixed integrally may be sufficient.

  FIG. 4 shows a perspective view of the second frame 5 as seen from the back side (lower side). As shown in FIG. 4, the second fixing means 19 of this embodiment includes an elastic band 26 for pressing and fixing the seamless mat 20 against the second frame 5.

  The elastic band 26 is, for example, a long band formed of a stretchable rubber or a stretch material. The elastic band 26 of the present embodiment extends in the bed width direction Y, and both ends 26 a and 26 a are respectively fixed to the seamless mat 20.

  The elastic band 26 of the present embodiment is wound around the second frame 5. The elastic band 26 of this embodiment is hung in the bed width direction Y of the tilting portion 14 b of the second frame 5. Such an elastic band 26 can prevent the seamless mat 20 from separating from the second frame 5 while allowing the other end S <b> 2 of the seamless mat 20 to be slidable in the bed length direction X. In the case where the second frame 5 does not include a reclining mechanism, the elastic band 26 is wound around, for example, the bed width direction Y of the base frame 13 of the second frame 5.

  Further, the second fixing means 19 of another aspect is formed on, for example, a guide rail formed in the second frame 5 extending in the bed length direction X and a lower surface of the seamless mat 20 that can be fitted to the guide rail. And a guided portion. Such second fixing means 19 can also prevent the seamless mat 20 from moving away from the second frame 5 while enabling the other end S2 side of the seamless mat 20 to be slidable in the bed length direction X.

  In the bed 1 of the present embodiment described above, when the seamless mat 20 is deformed from the folded state to the horizontal state due to the elasticity of the seamless mat 20 or the restraining force of the second fixing means 19, the seamless mat 20 deformed into an inverted V shape. There is a possibility that the top portion remains in a folded state and does not restore to a completely horizontal state. In this case, the seamless mat 20 can be easily restored to a horizontal state by being pressed by the user, for example.

  As an embodiment, the bed 1 may further include a biasing means 27 that biases the other end S2 side of the seamless mat 20 toward the outer edge side of the second frame 5 in the bed length direction. Such urging means 27 pulls the other end S2 side of the seamless mat 20 toward the outer edge side in the bed length direction X of the second frame 5 when the bed 1 is deformed from the folded state to the horizontal state, and seamlessly It helps to restore the mat 20 to a completely horizontal state along the second frame 5.

  The biasing means 27 is preferably an elastic body 28 that connects the outer edge side of the second frame 5 in the bed length direction X and the elastic band 26, for example. The elastic body 28 of the present embodiment has a long band shape made of elastic rubber or stretch material. When the bed 1 is deformed from the folded state to the horizontal state, the elastic body 28 is configured so that the other end S2 side of the seamless mat 20 is placed in the bed length direction X of the second frame 5 via the elastic band 26. The seamless mat 20 is restored to a completely horizontal state along the second frame 5 by being drawn toward the outer edge side.

  As mentioned above, although especially preferable embodiment of this invention was explained in full detail, this invention is not limited to embodiment of illustration, It can deform | transform and implement in a various aspect.
