[0013] On the other hand, the present application discloses a bedding including a support device.

[0014] The beneficial effects of the present application are as follows:

[0015] The present application discloses a support device for feet, including: a base assembly for connecting to a bed; a rotating assembly rotatably connected to the base assembly; a sliding assembly slidably connected to the rotating assembly; and a support pad connected to the sliding assembly. The main application of the support device of the present application is a nursing bed used by a person to be cared for. The usage method is as follows:

[0016] When the support device is not needed, the caregiver first operates the rotating assembly to rotate to a second angle to turn up the support pad, and operates the sliding assembly to extend so that the support pad is as far away from the bed as possible to prevent interference with the foot extension of the person to be cared for.

[0017] When the support device is needed, the caregiver operates the rotating assembly to rotate to a first angle to turn down the support pad close to the bed, and operates the sliding assembly to extend and retract according to the height of the person to be cared for to adjust the front and back positions of the support pad. At the same time, the headboard can be adjusted so that the person to be cared for maintains a comfortable semi-reclined or sitting and lying position. Of course, the headboard can also not be adjusted, and the person to be cared for can sit and lie on their own. Details are not described here.

[0018] When the caregiver maintains a comfortable reclined or sitting position, the sole of their foot can come into contact with the support pad, enabling the support device to support the caregiver's foot. This helps prevent issues such as excessive pressure on the abdomen, buttocks, and thighs due to lack of support on the sole, thus avoiding problems like discomfort from prolonged sitting, unstable posture, and tension in some body muscles. At the same time, when the caregiver needs to move their foot, they can also adjust the angle by rotating the rotating component to change the position of the support pad and ensure good support is provided in real-time.

[0019] In summary, through the angle adjustment of the rotating component and the telescopic adjustment of the sliding component in this application, the position of the support pad can be changed. On the one hand, this can enrich the adjustment methods of the support device and provide good support for the caregiver in real-time. On the other hand, it can complete the storage of the support device when not in use, avoiding affecting the extension of the caregiver's foot. Thus, the support device will bring a better support effect and user experience to the user. Brief Description of the Drawings

[0068] The present utility model will be further described below in conjunction with specific embodiments and the accompanying drawings. More details are elaborated in the following description to facilitate a full understanding of the present utility model. However, the present utility model can obviously be implemented in many other ways different from this description. Those skilled in the art can make similar extensions and deductions according to the actual application situation without violating the connotation of the present utility model. Therefore, the protection scope of the present utility model should not be limited by the content of this specific embodiment.

[0069] It should be noted that these and subsequent other drawings are only examples, and they are not drawn under the condition of equal proportion, and should not be used to limit the actual required protection scope of the present utility model.

[0070] In the related art, a support device for the feet is usually installed on one side of the foot of the bed to prevent problems such as excessive pressure on the abdomen, buttocks, and thighs, discomfort after sitting for a long time, unstable posture, and tension in some muscles of the body when the user maintains a sitting or reclining position on the bed due to lack of support on one side of the sole. It is commonly used in nursing beds, etc. However, its adjustment method is too single. Therefore, in order to improve the foot support effect of the support device, the technical solution of this application is generated. The following will be described in conjunction with Figures 1 to 17 elaborate.

[0071] According to an embodiment of the present application, a support device 1 for the feet is installed on a bedding, specifically as Figures 13 to 16 shown. The bedding includes a support device 1 and a bed 6. The bed is usually a nursing bed. The bed 6 has a headboard 61, a bed body plate 62, and a footboard 63 arranged in sequence. The headboard 61 is rotatably connected to the bed body plate 62. The support device 1 for the feet is provided on the side of the footboard 63 facing away from the headboard 61.

[0072] As Figure 1 , Figures 5 to 7 shown, the support device 1 includes a base assembly 10, a rotating assembly 20, a sliding assembly 30, and a support pad 40. Among them, the base assembly 10 is the installation foundation of the support device 1, and the base assembly 10 is used to connect the bed 6; the rotating assembly 20 is rotatably connected to the base assembly 10; the sliding assembly 30 is slidably connected to the rotating assembly 20; the support pad 40 is used to contact the user's feet, and the support pad 40 is connected to the sliding assembly 30.

[0073] The main application scenario of the support device 1 is as Figure 17 shown, which is a nursing bed used by the person to be cared for. The usage method is as follows:

[0074] When the support device 1 is not needed, the caregiver first operates the rotating assembly 20 to rotate to the second angle to turn up the support pad 40, and operates the sliding assembly 30 to extend, so that the support pad 40 is as far away from the bed 6 as possible to prevent interference with the extension of the feet of the person to be cared for, specifically as Figure 6 and Figure 16 shown.

[0075] When the support device 1 is needed, the caregiver will operate the rotating assembly 20 to rotate to the first angle to turn down the support pad 40 to be close to the bed 6, and operate the sliding assembly 30 to extend and retract according to the height of the person to be cared for to adjust the front and back position of the support pad 40, specifically as Figure 5 and Figure 15 shown. At the same time, the angle of the headboard 61 can be adjusted so that the headboard 61 is inclined relative to the bed body plate 62 to enable the person to be cared for to maintain a comfortable reclining or sitting position, such as Figure 17As shown, of course, the headboard 61 may not be adjusted, and the person to be cared for can sit or lie down by themselves, which will not be elaborated here.

[0076] When the person to be cared for maintains a comfortable reclining or sitting / lying position, the sole side of their foot can contact the support pad 40, so that the support device 1 supports the feet of the person to be cared for, thereby avoiding the situation where the sole side has no support and causing problems such as excessive pressure on the abdomen, buttocks, and thighs, and further preventing the person to be cared for from experiencing discomfort from sitting for a long time, unstable posture, and tension in some muscles of the body. At the same time, when the person to be cared for needs to move their feet, they can also adjust the angle by rotating the rotating component 20 to change the position of the support pad 40 to ensure good support is provided in real time.

[0077] In summary, through the angle adjustment of the rotating component 20 and the telescopic adjustment of the sliding component 30 in the embodiment of the present application, the position of the support pad 40 can be changed. On the one hand, this can enrich the adjustment methods of the support device 1 and provide good support for the person to be cared for in real time. On the other hand, it can complete the storage of the support device 1 when not in use to avoid affecting the foot extension of the person to be cared for. In this way, the support device 1 will bring better support effects and user experience to users.

[0078] Preferably, as Figure 1 and Figure 12 shown, the support device 1 further includes a first damping adjustment component 70. The first damping adjustment component 70 passes through the lugs of the base component 10 and the lugs of the rotating component 20 respectively. The first damping adjustment component 70 can be locked along its own axis so that the rotating component 20 can perform damped rotation around the first damping adjustment component 70. For example, the first damping adjustment component 70 includes a first adjustment bolt 71, a first adjustment nut 72, and a first adjustment gasket 73. The first adjustment bolt 71 passes through the base component 10 and the rotating component 20 in sequence. The first adjustment gasket 73 is sleeved on the first adjustment bolt 71. The first adjustment nut 72 is threadedly connected to the first adjustment bolt 71. The lug parts of the base component 10 and the rotating component 20 are located between the first adjustment nut 72 and the bolt head of the first adjustment bolt 71. By rotating the first adjustment nut 72, the base component 10 and the rotating component 20 can be made to approach and squeeze each other. In this way, a frictional force will be generated between the rotating component 20 and the base component 10 during rotation, achieving the effect of damped rotation. Under the damping effect, the rotating component 20 will fix its current position after rotating to a suitable angle, which is convenient for use.

[0079] Preferably, for the specific sliding connection method between the sliding component 30 and the rotating component 20, they can be slidably connected by setting a slider rail between the two, and the method adopted in the present application is as follows:

[0080] As Figure 2 、Figure 3 , Figure 10 and Figure 11 As shown in Figure 11 , the rotating assembly 20 includes a rotating member 21 rotatably connected to the base assembly 10. The rotating member 21 is provided with a first accommodating cavity 211. The sliding assembly 30 includes a sliding member 31. A part of the sliding member 31 is slidably disposed in the first accommodating cavity 211, and the other part of the sliding member 31 extends out of the first accommodating cavity 211 to connect to the support pad 40. In this way, the rotating assembly 20 can partially accommodate the sliding assembly 30 to improve the compactness of the device of the present application.

[0081] Preferably, the support device 1 may further include an adjustment assembly 50. The adjustment assembly 50 is disposed on at least one of the rotating member 21 and the sliding member 31. The adjustment assembly 50 is used to adjust the distance that the sliding member 31 extends out of the rotating member 21. In this way, by operating the adjustment assembly 50, the telescoping of the sliding assembly 30 and the fixing of the telescoping position can be facilitated, and the operation difficulty of the support device 1 can be simplified.

[0082] In some alternative embodiments, the adjustment assembly 50 can perform stepless adjustment on the telescoping of the sliding assembly 30. For example, the adjustment assembly 50 is set as an adjustment screw. The adjustment screw is rotatably disposed on the rotating assembly 20 and is in screw rotation cooperation with the sliding assembly 30, so as to realize the telescoping movement of the sliding assembly 30 by rotating the adjustment screw; or the adjustment assembly 50 is set as a lead screw drive mechanism. The lead screw is rotatably disposed on the rotating assembly 20. The lead screw nut is connected to the sliding assembly 30 and is in screw drive cooperation with the lead screw, so as to realize the telescoping of the sliding assembly 30; or the adjustment assembly 50 is set as a cylinder mechanism, a push rod mechanism or other mechanisms that can drive the telescoping of the sliding assembly 30 to change the position of the support pad 40. However, although stepless adjustment has high precision, the related device structure is precise and the cost is large. Considering the economy and applicability comprehensively, the sliding assembly 30 in the present application adopts stepped adjustment, which is specifically as follows:

[0083] Preferably, as Figure 1 , Figure 3 , Figure 6 and Figure 7 shown, the support device 1 further includes a positioning portion. One of the rotating member 21 and the sliding member 31 is provided with the adjustment assembly 50, and the other is provided with a plurality of positioning portions along the sliding direction X of the sliding assembly 30. For example, the rotating member 21 is provided with the adjustment assembly 50, and the sliding member 31 is provided with a plurality of positioning portions, or the rotating member 21 is provided with a plurality of positioning portions, and the sliding member 31 is provided with the adjustment assembly 50.

[0084] The adjustment assembly 50 can be locked to the positioning portion to fix the sliding assembly 30, and can be separated from the positioning portion to release the fixing of the sliding assembly 30, so that the sliding assembly 30 can slide. The principle is specifically as follows:

[0085] The sliding component 30 can slide to align the adjustment component 50 with a certain positioning portion; the adjustment component 50 can be in a stop fit with the corresponding positioning portion to limit the sliding of the sliding component 30. The positioning portion can be the positioning hole 212 described later, and the adjustment component 50 can be the pin structure described later, or other structures. For example, the adjustment component 50 is a gear provided on the rotating member 21, a rack is provided on the sliding member 31, and the tooth groove in the rack is the positioning portion. When the adjustment component 50 and the positioning portion mesh with each other to form a gear-rack transmission pair, when the gear meshes with tooth grooves at different positions, the telescopic degree of the sliding component 30 is different, and the protruding position of the support pad 40 is also different; or the adjustment component 50 is a pin, a rack is provided on the sliding member 31, and the tooth groove in the rack is the positioning portion. When the pin is inserted into tooth grooves at different positions, the telescopic degree of the sliding component 30 is different, and the protruding position of the support pad 40 is also different.

[0086] In summary, through the mutual cooperation between the adjustment component 50 and the positioning portion, a stepped adjustment of the telescoping of the sliding member 31 can be achieved, taking into account both economy and applicability.

[0087] Preferably, the positioning portion can be the positioning hole 212, and the adjustment component 50 can be a pin structure, which is specifically described as follows:

[0088] As Figure 2 、 Figure 3 、 Figure 7 and Figure 12 shown, the adjustment component 50 includes a movable pin 51 and an elastic member 52. The adjustment component 50 is installed on the sliding member 31, and the adjustment component 50 is located in the first accommodation cavity 211. The elastic member 52 elastically supports between the movable pin 51 and the sliding member 31.

[0089] The positioning portion is the positioning hole 212, the positioning hole 212 is provided on the rotating member 21, and the positioning hole 212 communicates with the first accommodation cavity 211. In use, the elastic member 52 can drive the movable pin 51 to extend into the positioning hole 212 to limit the sliding of the sliding component 30, thereby fixing the sliding component 30 at the current position; the movable pin 51 can be retracted into the first accommodation cavity 211 to separate from the positioning hole 212. At this time, the fixing of the sliding component 30 is released, and the sliding component 30 can be telescoped to adjust the position. The following further elaborates with an example.

[0090] In this application, a total of three positioning holes 212 are provided, which can be respectively denoted as the #1 positioning hole, the #2 positioning hole, and the #3 positioning hole arranged in sequence along the direction away from the base component 10 for convenience of description. In this way, the sliding component 30 has three gears of telescopic adjustment, which are respectively denoted as the first gear position, the second gear position, and the third gear position.

[0091] For example, when the movable bolt 51 extends into the #1 positioning hole, the sliding assembly 30 is fixed at the first gear position. When the sliding assembly 30 needs to be adjusted to the second gear position, the movable bolt 51 is pressed to make it withdraw from the #1 positioning hole. At this time, the elastic member 52 undergoes elastic deformation, and the sliding assembly 30 can slide to achieve expansion and contraction. When the sliding assembly 30 is adjusted to the second gear position, the elastic member 52 drives the movable bolt 51 to extend into the #2 positioning hole, thereby fixing the sliding assembly 30 at the second gear position. If the expansion and contraction position of the sliding assembly 30 needs to be adjusted again, the adjustment is carried out in the same way to ensure the convenience of the expansion and contraction adjustment.

[0092] Regarding the specific setting position of the adjustment assembly 50, the adjustment assembly 50 can be set in the gap between the sliding member 31 and the rotating member 21. However, such a layout method does not make full use of the design space. Therefore, the present application adopts the following setting method:

[0093] As Figure 2 、 Figure 3 、 Figure 7 and Figure 12 shown, the sliding member 31 is provided with a second accommodation cavity 311 and a through hole 312 communicating with the second accommodation cavity 311. For example, both the rotating member 21 and the sliding member 31 are rectangular tube structures to facilitate the setting of the accommodation cavity.

[0094] The movable bolt 51 includes a bolt head 511, a stop projection 512, and a rod body 513 arranged in sequence. Among them, the bolt head 511 is movably inserted through the through hole 312, and both the rod body 513 and the stop projection 512 are located in the second accommodation cavity 311. At least part of the stop projection 512 is offset from the through hole 312 along the movement direction of the movable bolt 51, so as to prevent the rod body 513 from sliding out of the second accommodation cavity 311 through the stopping action of the stop projection 512.

[0095] The elastic member 52 can be a spring. The elastic member 52 is sleeved on the rod body 513, and the elastic member 52 is elastically supported between the stop projection 512 and the cavity wall of the second accommodation cavity 311. The bolt head 511 can extend out of the second accommodation cavity 311 and extend into the positioning hole 212. The bolt head 511 can also be retracted into the second accommodation cavity 311 to be separated from the positioning hole 212. In this way, some components in the adjustment assembly 50 will be accommodated in the sliding member 31, thereby improving the structural compactness of the support device 1 of the present application.

[0096] Preferably, as Figure 3 、 Figure 8 and Figure 9 shown, the rotating assembly 20 further includes a guide sleeve 22. The guide sleeve 22 is connected to the rotating member 21. For example, the top of the rotating member 21 is provided with a cavity opening, the bottom of the rotating member 21 is connected to the base assembly 10, the guide sleeve 22 is arranged at the cavity opening position at the top of the rotating member 21, and the guide sleeve 22 sleeves the sliding member 31.

[0097] At least part of the guide sleeve 22 is disposed between the rotating member 21 and the sliding member 31. Specifically, at least part of the guide sleeve 22 extends into the first accommodation cavity 211 and is located in the avoidance gap P between the sliding member 31 and the rotating member 21. The avoidance gap P is Figure 11 a part of the first accommodation cavity 211. Such a design, on the one hand, can constrain the movement path of the sliding member 31 through the guiding action of the guide sleeve 22 to prevent the sliding member 31 from deviating from the sliding direction X; on the other hand, the guide sleeve 22 can separate the sliding member 31 from the rotating member 21 to prevent direct contact between the two, thereby reducing the contact position between the sliding assembly 30 and the rotating assembly 20, and further reducing the frictional force when the sliding assembly 30 slides, making the telescopic movement of the sliding assembly 30 smoother.

[0098] Preferably, as Figure 3 、 Figure 4 、 Figure 10 and Figure 11 shown, the guide sleeve 22 includes a mounting frame 221 and guide protrusions 222. The mounting frame 221 is connected to the rotating member 21, and the mounting frame 221 sleeves the sliding member 31. The guide protrusions 222 are disposed on the side of the mounting frame 221 facing the sliding member 31, and a plurality of guide protrusions 222 are arranged around the sliding member 31. For example, the guide protrusions 222 are arranged at the four corner positions of the mounting frame 221. In this way, the guide sleeve 22 will achieve guiding cooperation with the sliding member 31 along the sliding direction X through the synergistic action of the plurality of guide protrusions 222, which can further reduce the contact position between the sliding assembly 30 and the rotating assembly 20 and further improve the smoothness of the telescopic movement of the sliding assembly 30.

[0099] Preferably, as Figure 2 、 Figures 8 to 11 shown, the sliding assembly 30 further includes a guide piece 32. The guide piece 32 is located in the first accommodation cavity 211 and is between the rotating member 21 and the sliding member 31. Specifically, the top of the sliding member 31 is connected to the support pad 40, the bottom of the sliding member 31 is located in the first accommodation cavity 211, the guide piece 32 is detachably or fixedly connected to the sliding member 31, and a plurality of guide pieces 32 are arranged around the bottom of the sliding member 31. For example, the sliding member 31 is a rectangular tube structure, and one guide piece 32 is arranged on each of the four sides of the sliding member 31, with a total of four guide pieces 32 arranged. At least part of the guide piece 32 is located in the avoidance gap P and is between the guide sleeve 22 and the bottom of the first accommodation cavity 211.

[0100] Thus, in the first aspect, the guiding piece 32 can cooperate with the guiding sleeve 22 to jointly realize the guiding effect on the sliding part 31, so as to constrain the movement path of the sliding part 31 when it slides and ensure the sliding accuracy of the sliding part 31. In the second aspect, the stroke of the sliding assembly 30 can be limited to prevent the sliding assembly 30 from moving excessively; specifically, the guiding sleeve 22 and the guiding piece 32 are arranged oppositely along the sliding direction of the sliding assembly 30. In this way, when the sliding assembly 30 is retracted, the bottom of the first accommodating cavity 211 will stop the sliding part 31, specifically as Figure 8 and Figure 9 shown; when the sliding assembly 30 extends, the guiding sleeve 22 restricts the further movement of the sliding part 31 by stopping the guiding piece 32, specifically as Figure 10 and Figure 11 shown.

[0101] Preferably, as Figure 3 、 Figure 4 、 Figure 8 and Figure 9 shown, the rotating part 21 is provided with a mounting hole 213. A spring piece 223 is arranged on the mounting frame 221. The spring piece 223 is located in the avoidance gap P and extends towards the bottom of the first accommodating cavity 211. A mounting protrusion 224 is arranged on the spring piece 223, and the mounting protrusion 224 is received in the mounting hole 213.

[0102] In this way, it is convenient for disassembly and assembly between the rotating part 21 and the mounting frame 221. Specifically, during the process of inserting the mounting frame 221 into the rotating part 21 for assembly, the rotating part 21 will squeeze the spring piece 223 through the mounting protrusion 224, and the spring piece 223 will deform to make the mounting protrusion 224 yield, and then the mounting protrusion 224 enters the first accommodating cavity 211; when the mounting protrusion 224 reaches the mounting hole 213, the spring piece 223 rebounds to make the mounting protrusion 224 enter the mounting hole 213 to complete the assembly. During the process of disassembling the mounting frame 221 from the rotating part 21, press the mounting protrusion 224 to make the spring piece 223 deform, and the mounting protrusion 224 can exit the mounting hole 213, and then the mounting frame 221 and the rotating part 21 are separated from each other.

[0103] Preferably, as Figure 2 、 Figure 10 and Figure 11 shown, the sliding part 31 is provided with an avoidance groove 313; the avoidance groove 313 can be a rectangular opening or an opening of other shapes, and the avoidance groove 313 can be opened as a through groove to communicate with the second accommodating cavity 311. When the avoidance groove 313 slides with the sliding part 31 to correspond to the mounting protrusion 224, the mounting protrusion 224 can be separated from the mounting hole 213 and can drive the spring piece 223 to elastically deform, so that at least part of the spring piece 223 is received in the avoidance groove 313. The setting of the avoidance groove 313 will further avoid interference during the disassembly and assembly process, and the specific description is as follows:

[0104] During assembly, first, as shown in Figure 2 , install the guide piece 32 on the sliding member 31 to form a sliding assembly 30; then, place the mounting frames 221 in Figure 3 and Figure 4 over the sliding member 31, and on the side where the guide piece 32 faces the top of the sliding member 31. At the same time, align the mounting protrusions 224 and the elastic pieces 223 with the avoidance grooves 313; subsequently, insert the mounting frame 221 together with the sliding assembly 30 into the rotating member 21. When the mounting protrusion 224 touches the rotating member 21 during insertion, the rotating member 21 will squeeze the mounting protrusion 224, thereby driving the elastic piece 223 to deform towards the avoidance groove 313. In this way, at least part of the elastic piece 223, and even at least part of the mounting protrusion 224, will retract into the avoidance groove 313. The rotating member 21 and the mounting protrusion 224 will no longer block each other, and the installation interference is eliminated. Thus, the mounting frame 221 together with the sliding assembly 30 can continue to be inserted into the rotating member 21 until the mounting protrusion 224 enters the mounting hole 213.

[0105] During disassembly, first, extend the sliding assembly 30 to the position where the avoidance groove 313 corresponds to the mounting protrusion 224. Generally speaking, this position can be set as the limit position for the extension of the sliding assembly 30. In other words, this position can be the position when the guide sleeve 22 abuts against the guide piece 32, as specifically shown in Figure 10 and Figure 11 ; then, press the mounting protrusion 224 to drive the elastic piece 223 to deform and retract into the avoidance groove 313 until the mounting protrusion 224 exits the mounting hole 213. At this time, the rotating member 21 and the guide sleeve 22 can be separated, and then the sliding assembly 30 and the rotating assembly 20 can be separated to complete the disassembly.

[0106] It can be seen that through the setting of the avoidance groove 313, the disassembly and assembly of the rotating assembly 20 itself, as well as the disassembly and assembly between the rotating assembly 20 and the sliding assembly 30, become more convenient.

[0107] Preferably, the avoidance grooves 313 can be provided on two opposite sides of the sliding member 31, such as shown in Figure 2 . The elastic pieces 223 and the mounting protrusions 224 can also be provided on two opposite sides of the mounting frame 221, such as shown in Figure 3 , Figure 4 and Figure 11 , which can improve the connection stability.

[0108] Preferably, as shown in Figure 3 , Figure 6 , Figure 7 and Figure 12As shown, the rotating member 21 includes a base frame 21a and a bottom plate 21b. A first accommodation cavity 211 is provided in the base frame 21a, and the sliding member 31 is slidably provided in the base frame 21a. A first part of the bottom plate 21b is connected to the bottom of the base frame 21a to correspond to the sliding member 31; a second part of the bottom plate 21b extends outside the base frame 21a and is rotatably connected to the base assembly 10. For example, the first part is the middle area of the bottom plate 21b, and the second part is the two-wing areas of the bottom plate 21b. In this way, the part of the rotating member 21 for connecting the sliding member 31 and the part for connecting the base assembly 10 can be separated from each other, so that they do not interfere with each other, and at the same time, space can be reserved to operate the adjustment assembly 50, thereby realizing the telescopic adjustment of the sliding assembly 30.

[0109] Preferably, as Figure 3 , Figure 6 and Figure 7 shown, a baffle 113 is provided on one side of the base assembly 10 facing the bottom plate 21b. The rotating member 21 can drive the support pad 40 away from the base assembly 10 so that the bottom plate 21b abuts against the baffle 113, thereby realizing the limit of the rotating member 21 and preventing the excessive rotation of the rotating member 21.

[0110] Preferably, the support pad 40 is rotatably connected to the sliding assembly 30. In this way, the rotation of the rotating assembly 20 can realize the adjustment of the height position of the support pad 40, the telescopic movement of the sliding assembly 30 can realize the adjustment of the front and rear positions of the support pad 40, and the rotation of the support pad 40 can adjust its own inclination angle. In this way, it is possible to more conveniently adjust the fitting degree between the support pad 40 and the user's foot, and further improve the foot support effect of the support device 1.

[0111] Preferably, as Figure 1 and Figure 12As shown, the support device 1 also includes a second damping adjustment component 80, which passes through the support pad 40 and the sliding component 30 respectively. The second damping adjustment component 80 can be locked along its own axis so that the rotating component 20 can rotate around the second damping adjustment component 80 with damping. For example, the second damping adjustment component 80 includes a second adjusting bolt 81, a second adjusting nut 82 and a second adjusting gasket 83. The second adjusting bolt 81 passes through the ear of the support pad 40 and the end of the sliding component 30 in sequence. The second adjusting nut 82 is sleeved on the second adjusting bolt 81. The second adjusting nut 82 is threadedly connected to the second adjusting bolt 81. The ear portion of the support pad 40 and the end portion of the sliding component 30 are located between the second adjusting nut 82 and the bolt head of the second adjusting bolt 81. By rotating the second adjusting nut 82, the support pad 40 and the sliding component 30 can be brought close to each other and squeezed. In this way, the support pad 40 will generate friction with the sliding component 30 when rotating, thereby achieving the effect of damping rotation. Under the action of damping, the support pad 40 will fix the current position after rotating to a suitable angle, which is convenient for use.

[0112] Preferably, Figure 13 and Figure 14 As shown, the support pad 40 includes a connecting plate 41 and a pad body 42. The connecting plate 41 is connected to the sliding assembly 30. The pad body 42 is arranged on the side of the connecting plate 41 away from the sliding assembly 30. The hardness of the pad body 42 is less than that of the connecting plate 41. The pad body 42 can be a soft pad, such as a sponge pad, to improve the comfort of the foot support, and the connecting plate 41 can be a metal part to ensure the stability of the connection.

[0113] The present application also discloses a bedding, including the above-mentioned supporting device 1 and a bed 6. The bedding may be a bed assembly, or a sofa, a recliner, etc. The following description will continue with the bedding being a bed assembly, as follows:

[0114] Preferably, the support device 1 and the bed 6 can be fixedly connected, and the present application arranges that the support device 1 and the bed 6 are detachably connected to facilitate maintenance and replacement. At the same time, the bed 6 can also be equipped with a support device 1 as needed, which provides a wider degree of freedom in choice.

[0115] like Figure 8 and Figure 14 As shown, the base assembly 10 includes a base 11, an elastic pressure plate 12 and a fastening assembly 13. The rotating assembly 20 is rotatably connected to the base 11, a part of the elastic pressure plate 12 is fixed to the base 11, and another part of the elastic pressure plate 12 is spaced apart from the base 11, so that the elastic pressure plate 12 forms an elastic cantilever beam arranged below the base 11.

[0116] Specifically, the elastic pressure plate 12 has a fixed plate portion 121, an elastic plate portion 122 and a pressure plate portion 123 which are arranged in sequence. The fixed plate portion 121 is fixedly connected to the base 11, and the elastic plate portion 122 and the pressure plate portion 123 are spaced apart from the base 11. The fastening assembly 13 connects the pressure plate portion 123 and the base 11 respectively. The fastening assembly 13 may include a fastening bolt and a nut. The nut is arranged on the side of the pressure plate portion 123 away from the first support plate 111. The fastening bolt passes through the first support plate 111 and the pressure plate portion 123 in sequence, and is threadedly connected with the fastening bolt. The elastic pressure plate 12 can pass through the footboard 63 so that the footboard 63 is located in the area surrounded by the fastening assembly 13, the elastic pressure plate 12 and the base 11. Such a structure facilitates the disassembly and assembly between the support device 1 and the bed 6, which is specifically explained as follows:

[0117] During assembly, the elastic pressing plate 12 is passed through the footboard 63 so that the footboard 63 is located between the pressing plate portion 123 and the base 11, and then the fastening assembly 13 is installed, and the distance between the pressing plate portion 123 and the base 11 is adjusted by the fastening assembly 13. Specifically, by rotating the fastening bolts or nuts in the fastening assembly 13, the elastic pressing plate 12 is deformed, and then the pressing plate portion 123 and the base 11 are brought closer to each other, so that the footboard 63 is pressed between the pressing plate portion 123 and the base 11, and the installation and fixation of the support device 1 is completed. During disassembly, the fastening assembly 13 is first disassembled, and then the elastic pressing plate 12 is withdrawn from the footboard 63, and then the support device 1 and the bed 6 are separated.

[0118] Preferably, the distance between the elastic plate portion 122 and the base 11 increases gradually from the fixed plate portion 121 to the pressing plate portion 123 , so as to facilitate elastic deformation of the elastic pressing plate 12 .

[0119] Preferably, the base 11 includes a first support plate 111 and a second support plate 112 connected to each other, the first support plate 111 and the second support plate 112 extend in different directions, the first support plate 111 is mounted to the footboard 63 of the bed, the fixed plate portion 121 is fixed to the side of the first support plate 111 away from the second support plate 112, and the rotating assembly 20 is rotatably connected to the second support plate 112 and is spaced apart from the first support plate 111. After such assembly, the support pad 40 will maintain a certain distance from the bed 6, so as to better support the foot when in use, and not interfere with the user's foot extension when not in use.
