[0050] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings; obviously, the described embodiments are only a part of the embodiments of the present application, and not all the embodiments; based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without any creative labor fall within the protection scope of the present application.

[0051] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "provided with", "sleeved / connected", "connected" and the like should be understood broadly, for example, "connected" can be wall-mounted connection, can also be detachable connection, or integral connection, can be mechanical connection, can also be electrical connection, can be direct connection, can also be indirect connection through intermediate medium, can be internal communication of two elements, and those skilled in the art can understand the specific meaning of the above terms in the present application according to the specific circumstances.

[0052] Referring to FIGS. 1-17, the present embodiment provides a folding floating bed, comprising a soft cushion 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 first bed board frame or mattress 4 and a second bed board frame or backrest cushion 5 arranged in sequence along the width direction of the handrail;

[0053] The left handrail 2 and the right handrail 3 are respectively detachably rotatably connected with the second bed board frame or backrest cushion 5 through a folding hinge 21, 31; the soft cushion 1 is included in the corresponding backrest part 11 and the seat cushion part 12 of the second bed board frame or backrest cushion 5 and the first bed board frame or mattress 4; by connecting the second bed board frame or backrest cushion 5 and the folding hinge 21, 31, the rotation of the second bed board frame or backrest cushion 5 relative to the first bed board frame or mattress 4 can be realized, and the included angle between the second bed board frame or backrest cushion 5 and the first bed board frame or mattress 4 is adjusted, so that the floating bed can have backrests of different angles, and different postures can be adjusted to a more comfortable angle.

[0054] The second deck frame or backrest cushion 5 or the first deck frame mattress 4 respectively comprises a deck frame 51, 41 and an array of elastic units 6 arranged on the deck frame 51, 41; the array of elastic units 6 is divided into at least two groups to form a gap between adjacent elastic units 6 for folding the deck; thus the mattress 4 and the backrest cushion 5 can be folded to reduce the volume of the package. In this embodiment, the deck frame 51, 41 of the backrest cushion 5 or the mattress 4 comprises an outer frame 511, 411 and support rods 512, 412 arranged along the length direction of the outer frame 511, 411; the array of elastic units 6 is arranged on the support rods 512, 412 and the support rods 512, 412 pass through the elastic units 6. In order to enable the backrest cushion 5 or the mattress 4 to be folded, the outer frame 511, 411 is provided with a notch at the position corresponding to the gap. In order to avoid the exposed notch being unsightly and the structure being unstable, this embodiment further comprises a reinforcing and decorative member 5111, 4111 for covering the notch, as shown in Fig. 17; thus the outer frame 511, 411 on both sides of the notch is connected together to increase the connection strength of the outer frame 511, 411, and the reinforcing and decorative member 5111, 4111 can be removed when folding is required.

[0055] To fold and store the mattress 4 and the backrest cushion 5, the elastic units 6 are arranged on the mattress 4 and the backrest cushion 5, and 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 mattress 4 and the backrest cushion 5 due to the high height of the elastic units 6 in the released state, or the folding angle is large, and in addition, 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 of the mattress 4 and the backrest cushion 5, thereby avoiding 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, the two ends of the strap or cloth sleeve 66 are connected to the outer sides of the upper cover 61 and the base 62, respectively, and the spring 65 is arranged between the upper cover 61 and the base 62 and inside the strap or cloth sleeve 66; 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; then, in order to make the elastic unit 6 switch between the compressed state and the released state more conveniently, the elastic units 6 in the same group are connected to each other by a pull belt 7 in the embodiment; and the pull belt 7 comprises a release portion 71 matched with the upper cover 61 of the elastic unit 6, and a connecting portion 72 connected between adjacent two release portions 71; the plunger portion 71 has an insertion position and a disengagement position relative to the upper cover 61; when the plunger portion 71 is inserted into the upper cover 61, the upper cover 61 is pressed down, the locking member 611 is fixed in the locking position limited by the locking matching member 621, and the elastic unit 6 is in the compressed state; when the plunger portion 71 is in the disengagement position, the locking member 611 is disengaged from the locking position limited by the locking matching member 621, and the elastic unit 6 is in the released state.

[0056] Therefore, when the user needs to restore the elastic unit 6 to the released position, he only needs to pull one of the plunger portions 71 to move it from the insertion position to the disengagement position. At this time, due to the elastic restoring force of the elastic unit 6 corresponding to the plunger portion 71, the elastic unit 6 is restored to the released state, and the elastic restoring force is transmitted to the adjacent elastic unit 6 through the connecting portion 72 during the rising of the elastic unit 6, thereby moving the plunger portion 71 of the adjacent elastic unit 6 to the disengagement position. In this way, all the elastic units 6 in the group can be reset to the released state.

[0057] The locking member 611 is an expansion sleeve, and the locking matching member 621 is a limiting sleeve. The outer wall of the expansion sleeve extends radially outward to form one or more first limiting surfaces 6111. The first limiting surface 6111 of the expansion sleeve in the non-expanded state has an outer diameter smaller than the inner diameter of the opening 6211 of the limiting sleeve. The first limiting surface 6111 of the expansion sleeve in the expanded state has an outer diameter 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.

[0058] To achieve the expansion or expansion of the expansion sleeve, the plunger part is inserted. Specifically, the expansion sleeve is provided with a through channel 6112 along the height direction of the elastic unit 6; the plunger part is tightly matched with the through channel 6112 to change the expansion sleeve from the non-expanded state to the expanded state.

[0059] In addition, in order to control the depth of the plunger part inserted into the expansion sleeve, the inner wall of the expansion sleeve extends radially inward to form a second limiting surface 6113; the outer wall of the plunger extends radially outward to form a third limiting surface 711; when the plunger is in the insertion position, the second limiting surface 6113 and the third limiting surface 711 are limited and matched along the insertion direction.

[0060] In addition, the plunger part 71 and the base 62 are connected by a stabilizing rope 712, which passes through the through channel 6112. The stabilizing rope 712 can make the elastic unit 6 more stable during resetting and prevent the elastic band from springing up too far.

[0061] In order to facilitate the user to pull out the plunger, the elastic band 7 further comprises an operating part 73, which is connected with one of the plunger parts 71, and the plunger part 71 is moved from the insertion position to the disengagement position by applying external force to the operating part 73. In the embodiment, the operating part 73 is a pull ring.

[0062] 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.

[0063] To connect the side support vertical rods 8, the left handrail 2 and the right handrail 3 respectively comprise two support legs 25, 35 and a first horizontal rod 22, 32 and a second horizontal rod 23, 33 connected between the two support legs 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 carrying 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 and second clamping grooves are opposite, so as to avoid that when the second clamping groove is under load, the first clamping groove is separated from the second horizontal rod 23, 33.

[0064] In order to allow the side support vertical rods 8 to be folded and stored, the side support rods 8 comprise a connecting seat 81 and two connecting rods 82, one end of the connecting rod 82 is rotatably 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, as shown in FIG. 19 in the folded position. 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 this embodiment, the other end of the connecting rod 82 has a socket 821 which forms a detachable connection with the support leg 25, 35.

[0065] To achieve 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 communicates with the upper end face of the socket 821; the support leg 25, 35 is provided with a limiting block for being inserted into the limiting groove 822. When installing, the limiting block is 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 block enters the horizontal part of the L-shaped limiting groove 822, thus completing the connection of the support leg 25, 35 and the socket 821. When disassembling, just reverse the above operation.

[0066] 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 rotatably connecting with the connecting rod 82, and the vertical part 812 is used for forming a detachable connection with the middle support rod 9.

[0067] 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 bar 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 bar body 91 is provided with an L-shaped rib matched with the connecting port 8121, and the other end of the L-shaped rib is connected with the middle support bar body 91 to form an open 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 bar body 91 downward as a whole, so that the side wall of the connecting port 8121 is inserted into the clamping groove, and the hanging connection of the middle support bar 9 is completed.

[0068] The bed plate in the embodiment needs to be combined with the soft bag pad 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 pad 1 are provided with a connecting piece 14 connecting each other;

[0069] In the embodiment, since the bed plate is divided into the backrest pad 5 and the mattress 4, when the mattress 4 and the backrest pad 5 are placed along the horizontal direction in sequence, the mattress 4 and the backrest pad 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 pad 1. In this way, the connecting piece 14 is arranged on the three exposed edges of the mattress 4 and the backrest pad 5, which is convenient for the user to operate. In the embodiment, the connecting piece 14 is a zipper.
