FIG. 3 is an enlarged cross-sectional view in the vicinity of a first tilting portion in FIG. 2.

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 made of an elastic material arranged on the bed frame 2. Hereinafter, in the present embodiment, the direction of the bed 1 means a direction represented by X as a length, Y as a width, and Z as a height.

  The bed frame 2 includes a known upper body side frame 4 that mainly supports the user's upper body side, a lower body side frame 5 that mainly supports the user's lower body side, and a connecting frame 6 that foldably connects them. It has a folding mechanism.

  The upper body side frame 4 and the lower body side frame 5 have, for example, the same length. Thereby, the connection frame 6 is located at a substantially intermediate portion in the length direction of the bed 1.

  Each of the upper body side frame 4 and the lower body side frame 5 is provided with leg portions 7 on both sides in the width direction, for example. Each leg portion 7 is provided with wheels, for example. Such a leg portion 7 can easily move the bed 1. Each leg 7 is pivotally coupled to the frames 4 and 5 so as to be able to support the bed 1 even when the bed 1 is folded.

  The connection frame 6 of the present embodiment is rotatably connected to the upper body side frame 4 and the lower body side frame 5 with pins extending in the width direction. The connection frame 6 includes leg portions 8 extending in the height direction. The leg portion 8 can contact the floor surface in a state where the bed 1 is horizontal.

  The bed 1 as described above has a horizontal state in which the bed frame 2 is substantially horizontal, and a folded state in which the upper body side frame 4 and the lower body side frame 5 are folded in a substantially inverted V shape as shown in FIG. And can be transformed. As is well known, a resilient member such as a spring may be bridged between the upper body side frame 4 and the leg portion 8 in order to reduce the folding force.

  As a preferred embodiment, the bed 1 of this embodiment includes a reclining mechanism. FIG. 4 shows an enlarged plan view of the vicinity of the upper body side frame 4 for explaining the reclining mechanism, and FIG. 5 shows an enlarged side view thereof. The reclining mechanism of this embodiment includes, as the upper body side frame 4, a base frame 9 that is substantially rectangular in plan view, a tilting unit 10, and a driving unit 11 that tilts the tilting unit 10.

  The base frame 9 is held horizontally by the legs 7 and 8. The tilting part 10 is provided on the base frame 9, and in this embodiment, the first tilting part 10a on the head side and the second tilting on the upper body side connected to the tilting part 10 via the link 12 are provided. Part 10b. An end portion on the lower body side of the second tilting portion 10b is connected to the base frame 9 side via a pin 13 so as to be tiltable.

  For example, as shown in FIG. 7, the first tilting part 10a and the second tilting part 10b are covered with a cover together with a sponge material using, for example, urethane foam or polyethylene foam.

  The drive means 11 is an electric cylinder, for example, and is disposed below the upper body side frame 4. One end of the drive means 11 is connected to the upper body side frame 4 by a pin 14 so as to be tiltable, and a rod 15 that expands and contracts the drive means 11 is connected to an arm 16.

  One end of the arm 16 is connected to the rod 15 of the driving means 11 and the other end is connected to the first tilting portion 10a. In this embodiment, the arm 16 is connected to the first tilting portion 10a by a sliding pair so as to be movable along the length direction of the bed 1. Further, the arm 16 is connected to the base frame 9 with a pin 18 between one end and the other end.

  The upper body side frame 4 configured as described above contracts the rod 15 of the driving means 11 to make the bed surface of the bed 1 flat while extending the rod 15 as shown in FIGS. 1 and 2. Thus, as shown in FIG. 5, the upper body side frame 4 of the bed 1 can be lifted up to deform the bed 1 into a reclining state.

  In particular, in this embodiment, when the rod 15 of the driving means 11 is extended, first, only the first tilting portion 10a is lifted as shown in FIG. The bed 1 in such an initial reclining state can provide a pillow on the head side. When the rod 15 is further extended, the movable range of the link 12 reaches the maximum amount, and the first tilting portion 10a and the second tilting portion 10b can be integrally tilted further upward. The rod 15 can be operated with a remote controller (not shown).

  Although the details of the lower body side frame 5 are not shown, a reclining mechanism that can be bent into a mountain shape in a side view is preferably provided like the bed of Patent Document 1 described above. In this case, as shown in FIG. 2, the lower body side frame 5 can also include a base frame 30 and a tilting portion 31 placed on the base frame 30. The tilting part 31 may include a third tilting part 31a on the upper body side and a fourth tilting part 31b that is rotatably connected to the third tilting part 31a.

  As shown in FIGS. 1 and 2, the mat 3 includes a seamless mat 20 that continuously extends over the upper body side frame 4 and the lower body side frame 5. The seamless mat 20 is desirably formed of a sponge material using, for example, urethane foam or polyethylene foam.

  The seamless mat 20 extends continuously without being divided between the upper body side frame 4 and the lower body side frame 5. Therefore, as for the seamless mat 20, the edge of a mat is not located in the middle part of the length direction of the bed 1 like the past. Therefore, the seamless mat 20 distributes the load near the user's waist to the entire mat and provides the user with a comfortable sleeping comfort. Moreover, since the mat | matte edge of the seamless mat 20 is not located in the intermediate part of the length direction of the bed 1, there is no possibility that the sag there may arise early.

  The mat 3 may be composed of one seamless mat 20 that forms the entire range in the length direction of the bed 1. On the other hand, in the case of the bed 1 having a reclining mechanism as in this embodiment, it is also preferable to use a seamless mat 20 and another mat as the mat 3. In the present embodiment, as shown in FIG. 6, a case where the mat 3 includes a seamless mat 20 and a head mat 21 is shown. The head mat 21 is also preferably formed of a sponge material using, for example, urethane foam or polyethylene foam.

  Between the seamless mat 20 and the head mat 21 is the vicinity of the user's neck. In the vicinity of the neck, since there is relatively little contact with the bed surface, even if the mat is divided there, there is almost no sense of discomfort to the user.

  It is desirable that a gap S for preventing mutual contact is provided between the seamless mat 20 and the head mat 21. When in the reclining state, the seamless mat 20 may receive a force due to the rising of the second tilting portion 10b and try to move to the head side. At this time, if the gap S is not provided between the seamless mat 20 and the head mat 21, the two come into contact with each other and, for example, the seamless mat 20 or the head mat 21 is pressed and the bed surface There is a risk that an irregularly shaped bed surface may be formed. Further, even when the reclining is released, such deformation may remain on the bed surface. The gap S is effective in solving such a problem.

  In a further preferred embodiment, the first tilting part 10a includes a first holding part 23, for example. The first holding part 23 of the present embodiment is formed, for example, in a substantially U-shaped fence body, and is raised from the lower body side frame of the first tilting part 10a. The first holding unit 23 can prevent the head mat 21 from moving to the seamless mat 20 side.

  Similarly, the 2nd tilting part 10b contains the 2nd holding part 24, for example. Similar to the first holding unit 23, the second holding unit 24 is formed in, for example, a substantially U-shaped frame and is raised from the upper body side frame of the second tilting unit 10b. The second holding unit 24 can prevent the seamless mat 20 from moving to the head mat 21.

  By providing these first holding part 23 and second holding part 24, as shown in FIG. 7, the gap S between the seamless mat 20 and the head mat 21 is always maintained, and the reclining state, Even when the bed 1 is deformed in various states such as a folded state and a horizontal state, the positions of the mats 20 and 21 can be stably held.

  The head mat 21 of the present embodiment is only placed on the first tilting part 10a and is not fixed to the first tilting part 10a. Similarly, the seamless mat 20 is only placed on the second tilting portion 10b, the third tilting portion 31a, and the fourth tilting portion 31b, and is not particularly fixed thereto. Therefore, the mat 3 of the present embodiment includes a cover 22 that covers at least the upper surfaces of the seamless mat 20 and the head mat 21.

  The cover 22 of the present embodiment has, for example, a bag shape and seamlessly covers the seamless mat 20 together with the first tilting part 10a, the second tilting part 10b, the third tilting part 31a, and the fourth tilting part 31b. The positions of the mat 20 and the head mat 21 can be fixed on each tilting portion. The cover 22 is preferably formed from, for example, an elastic material. Thereby, the cover 22 can be expanded and contracted according to the shape of the mat 3 when the bed 1 is deformed in a horizontal state, a folded state, or a reclining state.

  Incidentally, in the folded state shown in FIG. 3, a restoring force is generated to return the seamless mat 20 to the horizontal state. This restoring force causes the seamless mat 20 (including the tilting portion) to be positioned away from the base frames 9 and 30 as indicated by phantom lines in FIG. However, such a state may lead to an increase in folding size.

  Therefore, the bed 1 of this embodiment is further provided with a detachable fixing means 33 that prevents the bed frame 2 and the seamless mat 20 from separating.

  The fixing means 33 includes, for example, a first fixing means 34 for fixing the upper body side frame 4 and the seamless mat 20 and a second fixing means 35 for fixing the lower body side frame 5 and the seamless mat 20.

  The first fixing means 34 includes, for example, a substantially plate-like fixing tool 36 that hangs from the end and the lower surface of the second tilting part 10b in the bed width direction Y, a hole 36a formed in the fixing tool 36, and a base It is comprised from the hole part 37 formed in the frame 9, and the lock pin 38 which can be inserted in the hole part 36a and the hole part 37 continuously.

  Similar to the first fixing means 34, the second fixing means 35 includes, for example, a fixture 39, a hole 39 a, a hole 40, and a lock pin 41. According to such fixing means 33, the seamless mat 20 can be easily attached to and detached from the bed frame 2 by inserting and removing the lock pins 38 and 41. Thereby, the fixing means 33 prevents the bed frame 2 and the seamless mat 20 from separating when the bed 1 is deformed into a folded state, and helps to store the bed 1 more compactly.

  The fixing means 33 may be formed in a long plate shape in which the fixing tool 36 of the first fixing means 34 reaches the base frame 30, for example. In the fixing means 33, the lock pin 41 of the second fixing means 35 is inserted into the holes 37, 39a and 40 continuously. Such a fixing means 33 is useful for preventing the bed frame 2 and the seamless mat 20 from separating and for locking the bed frame 2 in the folded state.

  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.
