[0063] Embodiment 1

[0064] With reference to Fig. 1-16, the present embodiment provides a folding floating bed, which comprises a soft mattress 1, a left handrail 2, a right handrail 3 and a bed board, and a connecting support assembly connected between the two handrails; the bed board comprises a mattress 4 and a backrest cushion 5 arranged in sequence along the width direction of the handrail;

[0065] The left armrest 2 and the right armrest 3 are respectively detachably and rotatably connected with the backrest cushion 5 through a folding hinge 21, 31; the soft bag cushion 1 is included in the backrest portion 11 and the seat cushion portion 12 corresponding to the backrest cushion 5 and the bed cushion 4; by connecting the backrest cushion 5 and the folding hinge 21, 31 through a rotating connection, the rotation of the backrest cushion 5 relative to the bed cushion 4 can be realized, and the included angle between the backrest cushion 5 and the bed cushion 4 is adjusted, so that the floating bed can have a backrest with different angles, and different postures can be adjusted to a more comfortable angle.

[0066] The backrest cushion 5 and the bed cushion 4 respectively include a bed plate frame 51, 41 and an array of elastic units 6 arranged on the bed plate frame 51, 41; the array of elastic units 6 is divided into at least two groups, and a gap for folding the bed plate is formed between adjacent elastic units 6; in this way, the bed cushion 4 and the backrest cushion 5 can be folded, and the volume of the package is reduced. In the embodiment, as shown in FIGS. 3 and 4, the bed plate frame 51, 41 of the backrest cushion 5 or the bed cushion 4 includes an outer frame 511, 411 and a support rod 512, 412 arranged along the length direction of the outer frame 511, 411; the array of elastic units 6 is arranged on the support rod 512, 412. In order to enable the backrest cushion 5 or the bed cushion 4 to be folded, the outer frame 511, 411 is provided with a notch at a position corresponding to the gap.

[0067] The mattress 4 and the backrest cushion 5 are folded and stored respectively, and the backrest cushion 5 and the mattress 4 are provided with elastic units 6. If the elastic units 6 are in the released state during folding, the elastic units 6 are likely to interfere with the folding of the backrest cushion 5 and the mattress 4 due to the high height of the elastic units 6 in the released state, and the folding angle is large. In addition, in order to reduce the volume of the mattress 4 and the backrest cushion 5 during storage, the elastic units 6 are fixed in the compressed position during folding and storage of the mattress 4 and the backrest cushion 5, so as to avoid the inconvenience caused by the high height of the elastic units 6 during folding and the large volume occupied during storage and transportation. Fig. 3 shows the spring in the compressed state, and Fig. 4 shows the spring in the released state. Therefore, the elastic unit 6 comprises a spring bracket and a spring 65. The spring bracket comprises an upper cover 61, a base 62, and a plurality of straps or cloth sleeves 66 connected between the upper cover and the base. As shown in Figs. 5 to 10, the two ends of the strap are respectively connected to the outside of the spring upper cover, and the spring is arranged between the upper cover 61 and the base 62. The upper cover 61 and the base 62 are provided with a locking member 611 and a locking matching member 621 at the opposite positions, so that the elastic unit 6 has a compressed state and a released state. In order to facilitate the switching of the elastic unit 6 between the compressed state and the released state, the elastic units 6 in the same group are connected to each other by a pull belt 7 in the embodiment. The pull belt 7 comprises a plunger part 71 matched with the upper cover 61 of the elastic unit 6, and a connecting part 72 connected between adjacent two plunger parts 71. The plunger part 71 has an insertion position and a disengagement position relative to the upper cover 61. When the plunger part 71 is inserted into the upper cover 61, the locking member 611 of the upper cover 61 is fixed in the locking position limited by the locking matching member 621, and the plunger part 71 is supported inside the locking member 611 to prevent the locking member 611 from retracting, so that the elastic unit 6 is in the compressed state. When the plunger part 71 is pulled out, the blocking member 611 of the upper cover retracts to the center, the locking member 611 is disengaged from the locking position limited by the locking matching member 621, and the spring 65 is elastically reset, so that the elastic unit 6 is in the released state.

[0068] Therefore, when the user needs to restore the elastic unit 6 to the released position, he only needs to pull one of the plunger parts 71 to move it from the insertion position to the disengagement position. At this time, due to the elastic restoring force, the elastic unit 6 corresponding to the plunger part 71 is restored to the released state. During the rising of the elastic unit 6, the elastic restoring force is also transmitted to the adjacent elastic unit 6 through the connecting part 72, driving the plunger part 71 of the adjacent elastic unit 6 to move to the disengagement position. In this way, all the elastic units 6 in the group can be reset to the released state.

[0069] In this embodiment, the locking member 611 is an expansion sleeve, and the locking matching member 621 is an inner flange of the limiting sleeve; the outer wall of the expansion sleeve extends radially outward to form one or more first limiting surfaces 6111; the outer diameter of the first limiting surface 6111 of the expansion sleeve in the non-expanded state is smaller than the inner diameter of the opening 6211 of the limiting sleeve; the outer diameter of the first limiting surface 6111 of the expansion sleeve in the expanded state is greater than the inner diameter of the opening 6211 of the limiting sleeve. In this way, in the non-expanded state, the expansion sleeve can be easily inserted into the limiting sleeve. Then, the expansion sleeve is placed in the expanded state, so that the locking member 611 and the locking matching member 621 are matched and locked, thereby fixing the elastic unit 6 in the compressed state.

[0070] To achieve the expansion or diameter expansion of the expansion sleeve, the plunger part is inserted. Specifically, the drawstring 7 is provided with one plunger part 71 corresponding to each spring in each row or column of springs, and the expansion sleeve is provided with a through channel 6112 in the height direction of the elastic unit 6; the plunger is tightly matched with the through channel 6112 to change the expansion sleeve from the non-expanded state to the expanded state.

[0071] In addition, in order to control the depth of the plunger inserted into the expansion sleeve, the inner wall of the expansion sleeve extends radially inward to form a ring of second limiting surfaces 6113; the outer wall of the plunger extends radially outward to form a ring of third limiting surfaces 711; when the plunger is in the inserted position, the second limiting surfaces 6113 and the third limiting surfaces 711 are limited and matched in the insertion direction.

[0072] In addition, the plunger 71 and the base 62 are connected by a stabilizing rope 712, the stabilizing rope 712 passes through the through channel 6112, and the stabilizing rope 712 can make the elastic unit 6 more stable during resetting and prevent the elastic unit 6 from tilting and the drawstring from springing up too far.

[0073] In order to facilitate the user to pull out the plunger, the drawstring 7 further comprises an operating part 73, the operating part 73 is connected with one of the plunger parts 71, and the plunger part 71 is moved from the inserted position to the disengaged position by applying external force to the operating part 73. In this embodiment, the operating part 73 is a pull ring.

[0074] As shown in FIG. 2, the connecting and supporting assembly comprises a side supporting vertical rod 8 and a middle supporting horizontal rod 9, the side supporting vertical rod 8 is detachably connected between the left handrail 2 and the right handrail 3; the middle supporting horizontal rod 9 extends in a direction parallel to the left handrail 2 or the right handrail 3, and one end of the middle supporting horizontal rod 9 is detachably connected with the side supporting vertical rod 8. The side supporting vertical rod 8 and the middle supporting horizontal rod 9 are used to increase the connection stability between the two handrails, and provide support to the mattress 4 through the middle supporting horizontal rod 9.

[0075] The left handrail 2 and the right handrail 3 are connected with the side support longitudinal rod 8, and each of the left handrail 2 and the right handrail 3 comprises two support feet 25, 35, a first horizontal rod 22, 32 and a second horizontal rod 23, 33 connected between the two support feet 25, 35; the second horizontal rod 23, 33 is below the first horizontal rod 22, 32 and is provided with a support 24, 34 for bearing the bed board frame 51, 41. Since the support 24, 34 needs to be clamped with the second horizontal rod 23, 33 and the bed board frame 51, 41, the support 24, 34 is provided with a first clamping groove for clamping with the second horizontal rod 23, 33 and a second clamping groove for clamping with the bed board frame 51, 41; the opening directions of the first clamping groove and the second clamping groove are opposite, so that the first clamping groove is separated from the second horizontal rod 23, 33 after the second clamping groove bears the weight.

[0076] In order to enable the side support longitudinal rod 8 to be folded and stored, the side support longitudinal rod 8 comprises a connecting seat 81 and two connecting rods 82, one end of the connecting rod 82 is rotationally connected with the connecting seat 81, so that the connecting rod 82 has an unfolded position and a folded position relative to the connecting seat 81. The other end of the connecting rod 82 needs to form a detachable connection with the left handrail 2 or the right handrail 3, in the embodiment, the other end of the connecting rod 82 has a socket 821 which forms a detachable connection with the support feet 25, 35.

[0077] In order to realize the detachable connection described above, the side wall of the socket 821 is provided with an L-shaped limiting groove 822, one end of which is communicated to the upper end face of the socket 821; the support feet 25, 35 are provided with limiting blocks which are inserted into the limiting groove 822. When installing, the limiting blocks are inserted from the top end of the vertical part of the L-shaped limiting groove 822 to the bottom of the vertical part, and then horizontally rotated so that the limiting blocks enter the horizontal part of the L-shaped limiting groove 822, thus completing the connection of the support feet 25, 35 and the socket 821. When disassembling, the above operation is reversed.

[0078] Since the connecting seat 81 needs to connect the connecting rod 82 and the middle support horizontal rod 9, the connecting seat 81 comprises a horizontal part 811 and a vertical part 812 which is vertically arranged with the horizontal part 811; the horizontal part 811 is used for rotationally connecting with the connecting rod 82, and the vertical part 812 is used for forming a detachable connection with the middle support horizontal rod 9.

[0079] In addition, the middle support crossbar 9 comprises a middle support bar body 91 and middle support feet 92, the middle support bar body 91 is detachably connected with the vertical part 812, and the middle support feet 92 are arranged along the length direction of the middle support bar body 91. In order to realize the connection between the middle support crossbar body 91 and the vertical part 812, the vertical part 812 is provided with at least one connecting port 8121 along the height direction; one end of the middle support crossbar 9 body is provided with an L-shaped rib matched with the connecting port 8121, one end of the L-shaped rib is connected to the middle support crossbar body 91 to form an opening downward clamping groove between the L-shaped rib and the middle support bar body 91. During installation, first insert a part of the L-shaped rib into the connecting port 8121, place the clamping groove above the side wall of the connecting port 8121, then move the middle support crossbar body 91 downward as a whole, so that the side wall of the connecting port 8121 is inserted into the clamping groove to complete the hanging connection of the middle support crossbar 9.

[0080] The bed plate in the embodiment needs to be combined with the soft bag cushion 1 to form a complete mattress, and therefore further comprises a surrounding edge 13 arranged along the circumference on the outer frame 511, 411, and the surrounding edge 13 and the soft bag cushion 1 are provided with a connecting piece 14 connecting each other;

[0081] In the embodiment, since the bed plate is divided into the backrest cushion 5 and the mattress 4, when the mattress 4 and the backrest cushion 5 are placed along the horizontal direction in sequence, the mattress 4 and the backrest cushion 5 have only three exposed edges to form a half-enclosed structure, and the remaining one edge is inward. Therefore, the surrounding edge 13 comprises a first part in a half-enclosed shape and a second part connected at the opening of the half-enclosed shape; and the connecting piece 14 is arranged at the first part and the area corresponding to the first part of the soft bag cushion 1. In this way, the connecting piece 14 is arranged on the three exposed edges of the mattress 4 and the backrest cushion 5, which is convenient for the user to operate. In the embodiment, the connecting piece 14 is a zipper.

[0082] Finally, in order to realize the rotary connection of the backrest cushion 5, the folding hinge 21, 31 comprises a first branch arm 211 and a second branch arm 311 hingedly connected at one end; the other end of the first branch arm 211 is fixedly connected with the left armrest 2 or the right armrest 3, and the other end of the second branch arm 311 is detachably connected with the backrest cushion 5. Specifically, the other end of the second branch arm 311 is provided with an insertion slot matched with the bed plate frame 51, 41 of the backrest cushion 5.

[0083] Referring to Figs. 17-18, the present embodiment also provides a packing method for the folding floating bed as described above, when the folding floating bed is packed into a packing box, the backrest part 11 and the seat cushion part 12 of the soft packing cushion 1 are stacked and folded, the elastic units 6 of the bed cushion 4 and the backrest cushion 5 are adjusted to the compressed state, and the bed cushion 4 and the backrest cushion 5 are respectively placed on the upper and lower sides of the soft packing cushion 1 after being folded along the gap; the side support tube and the middle support tube are respectively placed in the folded bed cushion 4 and the backrest cushion 5; the left armrest 2 and the right armrest 3 are stacked and placed above the soft packing cushion 1, so that the bed cushion 4 or the backrest cushion 5 is located between the armrest and the soft packing cushion 1.

[0084] Embodiment 2

[0085] Referring to Figs. 19-20, the difference between the present embodiment and Embodiment 1 is that the soft packing cushion 1 in the present embodiment is only one piece, and the area of the upper surface of the soft packing cushion 1 corresponds to the sum of the areas of the upper surfaces of the backrest cushion 5 and the bed cushion 4. Since only one soft packing cushion 1 is used, the zipper on the soft packing cushion 1 is continuously arranged along the circumference of the soft packing cushion 1.
