Next, the operation of each component of the sofa bed 1 with hanging bedding storage according to the present embodiment will be described.

First, let's talk about bed mode. The bed section 2 is arranged in a horizontal position as shown in FIGS. At this time, the front side of the bed section 2 is supported by the front convex section 42 and the sofa seat section 3 folded thereon. Further, the rear side of the bed portion 2 is supported by the rear projection portion 43 and the rotating link 84 in the upright state. That is, the bed portion 2 is stably supported in a horizontal position by the base portion 4, the rotating link 84, and the like.

The dust cover 9 and the comforter hanging means 6 are retracted from the bed surface 21 to the front side position, and arbitrary bedding is placed on the bed surface 21 . The dust cover 9 of this embodiment also functions as a blindfold covering the front side surface of the base portion 4 .

A mattress M is placed on the bed surface 21 . In this embodiment, a general single-type mattress M is placed, and the user can freely select the mattress M that suits his or her taste. In addition, deterioration due to use can be suppressed by appropriately replacing the front and back. When the mattress M deteriorates, it can be replaced with a new one. A favorite comforter K is put on the mattress M. The comforter K is not limited to one, and may be plural.

Next, the case of switching from the bed mode to the sofa mode will be described with reference to FIGS. 5 and 6. FIG.

As shown in FIG. 5 ( 1 ), the comforter hanging means 6 that has been retracted to the front side position is moved above the bed surface 21 . Specifically, the swing support arm 62 is swung to move the futon hanging bar 61 above the bed surface 21 . As a result, the futon hanging bar 61 is horizontally suspended from the head-side end surface 25 to the foot-side end surface 26 .

Next, as shown in FIG. 5(2), the quilt K is folded in half on the quilt hanging bar 61. Next, as shown in FIG. Also, the operation string 93 is pulled upward to lift the cover main body 91 . The cover swing support arm 92 swings backward to cover the comforter K with the cover main body 91. - 特許庁

Next, as shown in FIG. 5(3), the operation string 93 is pulled forward to start rotating the bed section 2 from the horizontal position in the standing direction. The forward/backward moving link 82 swings forward to move the rotation support shaft 81 forward. Since the lower edge of the forward/backward moving link 82 is curved and the base point vertical moving link 83 moves the base point 821 of the forward/backward moving link 82 downward, the forward/backward moving link 82 swings smoothly forward.

Further, the rotary link 84 swings forward in conjunction with the forward movement of the forward/backward moving link 82 . As a result, the bed portion 2 rotates around the rotation support shaft 81 so that the edge on the rear side is lowered.

As the rotation of the bed portion 2 progresses, as shown in FIG. and the axis C of are arranged in a straight line. When the inclination angle of the bed portion 2 exceeds this linearly aligned angle, as shown in FIG. On the other hand, the rotating link 84 swings forward in the same manner as before to rotate the bed section 2 toward the standing position. Since the rotation support shaft 81 in this embodiment is formed at a slightly rearward position from the front-rear central position of both side end surfaces of the bed portion 2, it is possible to easily perform the rotation operation with a smaller force based on the principle of leverage. .

Thereafter, the user continues to rotate the bed section 2 so as to lift the front side of the bed section 2, and rotates the bed section 2 to the standing position as shown in FIG. 6(3). The bed portion 2 is supported by being rotated to the standing position and leaning against the inclined support portion 45 of the rear convex portion 43 . As a result, the bed portion 2 is supported in an upright position in which the backrest surface 22 is exposed and slightly tilted backward. The rotary link 84 in this embodiment is arranged under the bed section 2 without becoming an obstacle because the bed section 2 side is bent in a doglegged shape.

As shown in FIGS. 5 and 6, the sofa seat portion 3 is not fixed to the front projection portion 42 of the base portion 4, so that the seat portion 3 is not fixed to the front convex portion 42 of the base portion 4, so that the movement of the bed portion 2 in the front-rear direction is accompanied by the movement of the sofa seat portion 3 during the pivoting operation. Move forward and backward. In this embodiment, since the bed portion 2 is slightly lifted by the front-rear movement link 82, the weight of the bed portion 2 is hardly applied to the sofa seat portion 3, and the sofa seat portion 3 is smoothly moved in the front-rear direction.

The bedding placed on the bed surface 21 rotates together with the bed portion 2 , but the mattress holding means 7 holds the mattress M on the bed surface 21 . Therefore, even if the bed part 2 falls backward in the standing position, the mattress M does not fall off the bed surface 21.例文帳に追加

Further, since the comforter K moves forward from the start of switching of the bed section 2 until it reaches a predetermined inclination angle, the comforter K rotates together with the bed section 2 without being caught even if there is not a sufficient gap between it and the rear wall. As shown in FIG. 6(3), it is hung by the comforter hanging means 6 and stored in the space formed on the side of the bed surface 21 of the bed section 2 . As a result, the comforter K can ensure air permeability, maintain a state in which night sweats can be dried, suppress the generation of mites, and the like, and can be kept clean.

In the sofa mode, as shown in FIG. 2, the seat surface 31 of the sofa seat portion 3 is exposed forward and becomes a sofa state. As shown in FIG. 9, the sofa seat part 3 in this embodiment can open and close the accommodation space provided in the base part 4 by folding it so as to contact the backrest surface 22 . In the storage space, bedding such as pillows and spare blankets that cannot be hung by the comforter hanging means 6 and various items other than the bedding can be freely stored.

Next, when switching from the sofa mode to the bed mode, as shown in FIGS. 7 and 8, the bed portion 2 is rotated from the standing position to the horizontal position. In this embodiment, as shown in FIG. 7(1), the operation string 93 is pulled forward or the bed 2 is tilted forward.

The forward/backward moving link 82 swings forward to move the rotation support shaft 81 forward. The rotary link 84 swings so as to stand rearward in conjunction with the movement of the forward/backward moving link 82 , and rotates the bed portion 2 around the rotary support shaft 81 .

As shown in FIG. 7(2), the inclination angle of the bed portion 2 is such that the base point A of the rotation link 84, the connection point B, and the axis C of the rotation support shaft 81 are aligned in a straight line when viewed from the side. As shown in FIG. 7(3), when the tilt angle is exceeded and rotated in the horizontal position direction, the swinging direction of the forward/backward moving link 82 switches to the rearward side. As a result, the front-rear moving link 82 swings rearward to move the rotary support shaft 81 rearward. On the other hand, the rotary link 84 swings so as to stand rearward in the same direction as before, and lifts the rear edge of the bed section 2 .

Then, as shown in FIG. 8( 1 ), both left and right ends of the longitudinal edge on the rear side of the bed portion 2 are placed on the rear convex portion 43 of the base portion 4 . At this time, since the rotary link 84 is bent in a doglegged shape, it is placed on the rear convex portion 43 so as to push the bed portion 2 rearward. As a result, the pivoting link 84 and the forward/backward moving link 82 stop swinging. The sofa seat portion 3 is folded under the front side of the bed portion 2 , and the sofa seat portion 3 is supported by the front convex portion 42 .

Also, the dust cover 9 covering the comforter K is retracted to the front side position, and the comforter K folded in two is arranged in a flat state.

Then, as shown in FIG. 8(2), the futon hanging bar 61 on the bed surface 21 is retracted to the front side position, and the switching from the sofa mode to the bed mode is completed.

According to the above-described sofa bed 1 with hanging bedding storage of the present embodiment, the following effects can be obtained.
1. In the sofa mode, the comforter K can be hung in a folded state and stored behind the bed part 2. - 特許庁
2. The comforter K hung in a folded state has high air permeability and can be kept clean.
3. Since the mattress M is detachable, deterioration can be suppressed by selecting a favorite mattress M and replacing the front and back.
4. Since the futon hanging bar 61 can be retracted to the front side position, sleep is not disturbed.
5. By providing a storage space under the sofa seat part 3, a pillow or the like which cannot be hung by the comforter hanging means 6 can be stored.
6. Since the bed part 2 can be moved forward at the start of rotation by the mode switching means 8, even if there is no sufficient space between the bed part 2 and the wall on the rear side, the comforter K can be rotated in a suspended state. operation can be performed.
