Detailed Implementation

[0040] Figures 1 to 3This invention displays a first preferred embodiment of a support device 100 that adapts to changes in human posture according to the present invention. The device includes a base 1, a movable component 2, a human body support component 3, a second driving component 4 for driving the deformation of the human body support component 3, and a first driving component 5 for driving the deformation of the movable component 2. The human body support component 3 may optionally lack deformability; in this case, the second driving component 4 can be omitted.

[0041] The base 1 includes a frame 11, two sliding components 12, four wheels 13 and a foot pedal 14.

[0042] The frame 11 includes two bottom frame strips 111, an inner frame strip 112, two vertical frame strips 113, two load-bearing frame strips 114, a pivot frame strip 115, an outer frame strip 116, and a pivot part 117.

[0043] The two bottom frame strips 111 of the frame 11 extend along a second direction D2 and are spaced apart from each other. The inner frame strip 112 extends along a first direction D1 perpendicular to the second direction D2, and the two ends of the inner frame strip 112 are respectively connected to the two bottom frame strips 111.

[0044] The two ends of the two upright frame strips 113 of the frame 11 are fixedly connected to the two ends of the two bottom frame strips 111. The two load-bearing frame strips 114 extend along the second direction D2 and are connected to the two upright frame strips 113. In this first preferred embodiment, both upright frame strips 113 are in the shape of an arch.

[0045] The pivot frame 115 of frame 11 is disposed between and fixedly connected to the two upright frame 113, and the pivot frame 115 has two pivot portions 1151 spaced apart from each other. The outer frame 116 is disposed between and fixedly connected to the two bottom frame 111, and the outer frame 116 is located below the pivot frame 115. The pivot portion 117 is disposed between the inner frame 112 and the outer frame 116, and the two ends of the pivot portion 117 are respectively fixedly connected to the inner frame 112 and the outer frame 116.

[0046] The two sliding components 12 of the base 1 each include a slide rail 121, a slider 122, and a pivot seat 123. The slide rail 121 extends along the second direction D2 and is fixedly mounted on the support frame 114, while the slider 122 is movably fitted onto the slide rail 121 along the second direction D2. The pivot seat 123 is fixed to the slider 122, thereby reciprocating with the slider 122 in the second direction D2.

[0047] The four wheels 13 of the base 1 are disposed at the bottom of the frame 11, thereby enabling the base 1 to move. Although in this embodiment the base 1 has the function of movement through the four wheels 13, the base 1 may also not have the wheels 13 and only provide a supporting function. The foot pedal 14 is fixedly connected to the inner frame strip 112 and the two bottom frame strips 111.

[0048] The movable component 2 includes a rear frame 21, two side frame strips 22, a front frame 23, a front pivot frame 24, two cranks 25, and a rear pivot frame 26. The rear frame 21 extends along a first direction D1. The side frame strips 22 are respectively connected to both sides of the rear frame 21 and extend along a second direction D2, and each side frame strip 22 is provided with a sliding component 221 extending along the second direction D2 (indicated in...). Figure 4 (Only one is shown in the figure). In this first preferred embodiment, each sliding component 221 is a slide rail.

[0049] The front frame strip 23 of the active component 2 extends along the first direction D1 and is fixed to one end of the side frame strips 22. For example... Figure 2 As shown, the front pivot frame 24 is connected to the center of the two side frame 22 respectively, and the center of the front pivot frame 24 is further provided with a pivot seat 241.

[0050] The two ends of the two cranks 25 of the movable component 2 are pivot seats 1151 respectively pivotally connected to the front pivot frame 24 and the pivot frame 115 of the base 1. The rear pivot frame 26 is fixed to the two side frame bars 22, and each end of the rear pivot frame 26 has a round tube 261, which is pivotally connected to the two sliding components 12 of the base 1. Therefore, when the cranks 25 are driven to rotate, or when the sliders 122 are driven to slide, the movable component 2 will produce an angle change relative to the base 1. In this first preferred embodiment, the present invention drives the movable component 2 to move by the rotation of the cranks 25.

[0051] The human body support component 3 includes a footboard 31, a legboard 32, a backrest 33, two handrails 34, a lower restraint 35, and an upper restraint 36.

[0052] The footplate 31 has a first end 311 and a second end 312 opposite to each other, the first end 311 being pivotally connected to the rear frame 21 of the movable assembly 2. The leg plate 32 has a first end 321 and a second end 322 opposite to each other, and the first end 321 of the leg plate 32 is pivotally connected to the second end 312 of the footplate 31. The backplate 33 is pivotally connected to the second end 322 of the leg plate 32 and is movably disposed on the two side frame strips 22 along the second direction D2. Figure 2 As shown, the bottom of the back plate 33 is provided with four sliders 331, which are respectively fitted onto the two sliding components 221 of the movable component 2 (see...). Figure 4 This allows the back plate 33 to reciprocate along the second direction D2. Furthermore, a connecting seat 332 is provided at the center of the back plate 33.

[0053] In this first preferred embodiment, the first end 311 of the footplate 31 is pivotally connected to the rear frame 21 of the movable component 2, and the first end 321 of the legplate 32 is pivotally connected to the second end 312 of the footplate 31. Since the backplate 33 is movable along the second direction D2 and is pivotally connected to the second end 322 of the legplate 32, the human body support component 3 will deform when the backplate 33 is driven to slide.

[0054] The two handrails 34 are fixed to both sides of the back panel 33, the lower clamp 35 is set on the foot plate 31, and the upper clamp 36 is set on the back panel 33; wherein, the lower clamp 35 and the upper clamp 36 are both fasteners such as belts that have the function of tightening and fixing.

[0055] The second drive assembly 4 includes a drive cylinder 41 and a movable member 42. The drive cylinder 41 is fixed to the rear frame 21, and the movable member 42 is telescopically disposed in the drive cylinder 41, with one end of the movable member 42 pivotally connected to the connecting seat 332 of the back plate 33. The second drive assembly 4 can drive the back plate 33 to move in the second direction D2 by controlling the telescopic movement of the movable member 42 through the drive cylinder 41.

[0056] The first drive assembly 5 includes a drive cylinder 51 and a movable member 52. The drive cylinder 51 of the first drive assembly 5 is pivotally connected to the pivot portion 117 of the base 1. The movable member 52 of the first drive assembly 5 is telescopically disposed within the drive cylinder 51, and one end of the movable member 52 is pivotally connected to the pivot seat 241 on the front pivot frame 24. Therefore, the first drive assembly 5 can drive the movable component 2 and the human body support component 3 to rotate relative to the base 1 by controlling the telescopic movement of the movable member 52 through the drive cylinder 51.

[0057] In this invention, the use of the first driving component 5 to drive the movable component 2 to rotate relative to the base 1 is only one driving method selected by this invention. Other driving methods can also be used, and are not limited to the above. For example, ... Figure 11 As shown, a motor 5a can be connected to the pivot of the crank 25a, causing the motor 5a to rotate the crank 25a, thereby causing the movable component 2 to rotate relative to the base 1. This driving method will be described in more detail later, and will not be repeated here. For example, as... Figure 12 As shown, a motor 5c is directly connected to a screw 121c, so that the motor 5c drives the screw 51c to rotate, thereby driving a nut 122c to move linearly along the screw 51c, which in turn drives the crank 25 to rotate, causing the movable component 2 to rotate relative to the base 1, as shown. Figure 13As shown. In this driving method, the screw 121c and the nut 122c screwed onto it replace the aforementioned slide rail 121 and slider 122, respectively. In other words, the screw 121c can be regarded as the slide rail 121, and the nut 122c can be regarded as the slider 122. Furthermore, regardless of which driving method the first driving assembly 5 adopts, the power it provides can cause the movable assembly 2 to rotate relative to the base 1 and move with the slider 122 (or nut 122c), regardless of the position from which the power is input to the movable assembly 2.

[0058] As described above, the bearing device 100 of the present invention mainly connects the crank 25 of the movable component 2 to the pivot seat 1151 of the base 1 and the round tube 261 to the pivot seat 123 of the base 1. In this way, when the first drive component 5 controls the crank 25 to rotate relative to the base 1, the movable component 2 can be rotated and displaced.

[0059] More specifically, when the first drive assembly 5 changes the position of the front pivot frame 24 by moving the movable member 52, since the front pivot frame 24 is pivotally connected to the crank 25 and the round tube 261 is pivotally connected to the pivot seat 123, the side frame 22 of the movable assembly 2 will rotate relative to the base 1 with the round tube 261 as the axis of rotation, and the round tube 261 will also move along the slide rail 121 in the second direction D2, thereby changing the angle of the side frame 22 from parallel to the bearing frame 114 to perpendicular to the bearing frame 114. The displacement change of the round tube 261 caused by the aforementioned angle change can minimize the impact of the overall center of gravity change caused by the rotation of the side frame 22.

[0060] Furthermore, since the human body support component 3 of the support device 100 of the present invention also has the aforementioned foot plate 31, leg plate 32, and back plate 33, the position of the back plate 33 can be changed by driving the slider 331 of the back plate 33 to move through the second drive component 4, thereby enabling the human body support component 3 to... Figure 3 and Figure 4 The unfolded flat mode shown is similar to Figure 7 The diagram shows how to switch between two lying-flat modes with legs retracted.

[0061] In this first preferred embodiment, both drive cylinder 41 and drive cylinder 51 are electric drive cylinders, which are driven by electricity to extend or retract the moving part 42 or the moving part 52. However, in other embodiments, they are not limited to this. Drive cylinder 41 and drive cylinder 51 can also be replaced by manual drive cylinders, so that the moving part 42 or the moving part 52 can be extended or retracted by human operation. In addition, besides manual drive cylinders, drive cylinder 41 and drive cylinder 51 can also be replaced by hydraulic drive cylinders or pneumatic drive cylinders, etc., which are driven by various power sources.

[0062] like Figures 1 to 6As shown, when the carrier device 100 of the present invention is in Figure 3 In the unfolded, reclining mode, the upper restraint 36 can be used to secure the user 200's body to the back panel 33. Next, the user 200 can control the second drive assembly 4 to retract the moving member 42 into the drive cylinder 41. At this time, guided by the slider 331 of the back panel 33, the back panel 33 can move in the opposite direction D2. Since the first end 311 of the footboard 31 is pivotally connected to the rear frame 21 of the movable assembly 2, the movement of the back panel 33 will cause the legboard 32 to bend relative to the footboard 31 and the back panel 33, as shown... Figure 5 and Figure 6 As shown.

[0063] like Figure 7 As shown, when the back plate 33 is moved away from the second direction D2 and to one end of the sliding assembly 221 by the moving member 42, the leg plate 32 forms a first angle R1 relative to the back plate 33, and the leg plate 32 forms a second angle R2 relative to the foot plate 31, which is smaller than the first angle R1. The first angle R1 is between 80 degrees and 100 degrees, and the second angle R2 is between 30 degrees and 60 degrees. Figure 7 In the diagram, the first included angle R1 and the second included angle R2 are 90 degrees and 30 degrees, respectively.

[0064] When user 200 uses the second drive component 4 to move the back panel 33, thereby switching the support device 100 of the present invention from the unfolded flat-lying mode to the retracted flat-lying mode, the first drive component 5 can then be used to rotate the movable component 2 and the human body support component 3, thereby switching the support device 100 of the present invention from the retracted flat-lying mode to... Figure 8 The kneeling-standing posture shown is combined with... Figure 9 As shown, user 200 can then control the second drive component 4 to push the moving part 42 outward, so that the back plate 33 moves back to its original position. At this time, the bearing device 100 of the present invention switches from the kneeling upright mode to the standing mode. Figure 10 The image shows a standing posture.

[0065] As described above, since the user 200's body is fixed to the back panel 33 using the upper restraint 36, the user 200 can be switched from a lying position with legs retracted to a standing position by the human body support component 3. During this posture change, the user 200's upper body can not only be prevented from tilting by the upper restraint 36, but also be secured by the two handrails 34, and there is a foot pedal 14 for the user 200 to step on. Furthermore, the lower restraint 35 provides support and reaction force to the user 200's knees and feet when standing, until the user 200 completes the standing posture. Therefore, the user 200 can indeed easily change from a lying position to a standing position using the support device 100 of the present invention, effectively increasing the user 200's convenience in daily life.

[0066] Figure 11 This invention shows a second preferred embodiment of the present invention, which discloses another support device 100a that changes shape in response to changes in human posture. It is similar to the support device 100 described above in the present invention, and also includes a support base 1a, a movable component 2a, a human body support component 3a, a second drive component 4a, and a first drive component 5a.

[0067] As described above, the main difference between the bearing device 100a and 100 of the present invention is that the first drive component 5a of the bearing device 100a is disposed on the pivot frame 115a of the base 1a and connected to one end of the two cranks 25a. Therefore, the first drive component 5a can provide torque to drive the two cranks 25a to rotate relative to the base 1a, thereby driving the connected front pivot frame 24a to move. Since the front pivot frame 24a is connected to the side frame 22a, and the side frame 22a is also movably connected to the sliding component 12a through the rear pivot frame 26a, when the first drive component 5a drives the two cranks 25a to rotate relative to the base 1a, the movable component 2a will drive the human body bearing component 3a to rotate and stand up or lie down.

[0068] Furthermore, in the second preferred embodiment, the drive cylinder (not shown) of the second drive assembly 4a is an electric drive cylinder, which uses electricity to drive the moving part (not shown). However, the second drive assembly 4a can also be replaced by a manual drive cylinder, a hydraulic drive cylinder, or a pneumatic drive cylinder. On the other hand, in the second preferred embodiment, the first drive assembly 5a is a motor drive device, which can use electricity to drive a motor to rotate the two cranks 25a relative to the base 1a. However, the first drive assembly 5a can also be a manual drive cylinder, a hydraulic drive cylinder, or a pneumatic drive cylinder.

[0069] Figures 14 to 17This invention shows a third preferred embodiment of the present invention, in which the bearing device 100b that changes shape according to the needs of human posture changes is generally the same as the first preferred embodiment described above. The main difference is that the third preferred embodiment of the present invention uses two retractable sliding components 221b to replace the sliding component 221 of the movable component 2 and the slider 331 of the back plate 33. More specifically, in the third preferred embodiment, each sliding component 221b is a multi-section telescopic rod with a retractable length. A first section 221b1 of each sliding component 221b is fixed to each side frame 22b of a movable component 2b. A second section 221b2 of each sliding component 221b slides on the first section 221b1 and can slide relative to it. A third section 221b3 of each sliding component 221b slides on the second section 221b2 and can slide relative to it. Each third section 221b3 is connected to the back plate 33 of a human body support component 3b. Figure 15 As shown, in the third preferred embodiment, the back plate 33 has two rows of six connecting pieces 301b, with three connecting pieces 301b in each row arranged at intervals along the second direction D2 and connected to the third section rod 221b3.

[0070] Another key difference is that the third preferred embodiment of the present invention uses two sliding components 12b instead of the sliding component 12 of the base 1 described above. More specifically, a slider 122b of each sliding component 12b is directly slidably fitted onto the two support frame bars 144b of the base 1b, allowing the two sliding components 12b to slide along the two support frame bars 144b. In this case, the support frame bars 144b can be regarded as the slide rails of the base 1b. Furthermore, a pivot seat 123b of each sliding component 12b is not only fixed to each slider 122b, but also pivotally connected to the two circular tubes 261b of the movable component 2b. Figure 16 Each circular tube 261b is inserted into a circular hole 120b on each pivot 123b and is screwed into a threaded hole H in the circular tube 261b by a bolt assembly T. The circular tube 261b can rotate within the circular hole 120b.

[0071] Furthermore, in the third preferred embodiment, the two armrests 34b are located on both sides of the leg panel 32, unlike the first preferred embodiment where the two armrests 34 are located on both sides of the back panel 33, and their shapes are also different. As for the other components of the third preferred embodiment, since they are substantially the same as or similar to the corresponding components of the first preferred embodiment, they will not be described in detail. And precisely because of this, Figures 14 to 17 The numbering of these components is still in use. Figures 1 to 3 The labels in the text.

[0072] Depend on Figures 17 to 21It can be seen that when the first drive assembly 5 pushes the movable assembly 2b upward, through the linkage of the two cranks 25, the movable assembly 2b, which was originally in a horizontal state, rotates about the circular tube 261b as the axis of rotation and becomes upright, in conjunction with... Figure 10 The difference is that the active component 2b is tilted at a slight angle rather than standing vertically. Meanwhile, as... Figure 20 and Figure 21 As shown, the movable component 2b also moves a certain distance into the base 1b as the two sliding components 12b slide, and the human body support component 3b mounted on the movable component 2b also moves in the same way. Conversely, when the first drive component 5 pulls the movable component 2b down, the movable component 2b, which is in an upright state, will flip back to its original position and become horizontal. In addition, by controlling the extension length of the moving part 52 of the first drive component 5, the flipping angle of the movable component 2b can be adjusted, thereby determining the tilt angle of the movable component 2b.

[0073] Depend on Figures 20 to 23 It is known that when the moving part 42 of the second drive assembly 4 retracts, it will cause the third section 221b3 of each sliding assembly 12b to retract into the second section 221b2, and the second section 221b2 to retract into the first section 221b1, thereby causing the back panel 33 to move downward. The downward movement of the back panel 33 will push the leg plate 32 pivotally connected to it, causing the back panel 33, leg plate 32 and foot plate 31 pivotally connected to each other to bend to form a seat.

[0074] As can be seen from the description of the above embodiments of the present invention, the present invention mainly utilizes the above-mentioned base and its slider, the above-mentioned movable component and its front pivot frame and crank, and the first drive component to enable the human body support component set on the movable component to have a stable flipping ability, thereby enabling the user on the human body support component to easily change from a lying position to a standing position or a sitting position, and the reverse change of position is also very easy, thus increasing the convenience of the user in life.

[0075] Furthermore, although there are two sets of sliding components and cranks in the above preferred embodiments, it is also possible to use only one set of each, or three or more sets of each, depending on the situation.
