DETAILED DESCRIPTION

[0037] In order to fully disclose the present application to those skilled in the art, the technical solutions in the embodiments of the present application will be described in detail below with reference to the accompanying drawings in the embodiments of the present application.

[0038] The nursing support disclosed in the present application can be divided into a fixed version and a mobile version. The fixed version refers to a version in which the rack of the nursing support needs to be fixedly installed on a wall or the ground or other reliable objects during use. The mobile version refers to a version in which the rack of the nursing support is installed with supporting legs 108, so that the nursing support can be self-balanced and mobile during normal use without relying on other objects.

[0039] For ease of understanding and description, the directional relationship of this invention is set as follows: when the user sits on this nursing support, the direction the user faces is the front of the nursing support, and the direction above the user's head is the top of the nursing support. The usage environment is set as a bathroom combined with a toilet, which has relatively strict requirements for the nursing support. Of course, a nursing support that can be used with a toilet is also suitable for use in environments without a toilet.

[0040] like Figure 1 , Figure 8 , Figure 9 As shown in the illustration, this embodiment exemplifies a postural repositioning nursing support. The nursing support is a spatial linkage mechanism, including a support system 1, a roller blind system 2, a power system 3, and a control system. The support system 1 includes a swing frame 103 and a first support 101 providing a fulcrum for the swing of the swing frame 103. The swing frame 103 includes a swing arm and a swing rod 1033. The roller blind system 2 includes a roller 201 and a curtain 202. Both ends of the curtain 202 are fixed to the roller 201 and the swing rod 1033, respectively. The roller 201 is connected to the power system 3 and is mounted on the upper part of the support system 1. Figure 1 , Figure 9 The second U-shaped bracket 102 is used as the frame. Figure 8 Using the first support 101 as the frame, driven by the power system 3, the swing arm 1033 swings up and down with the swing frame 103. Driven by the power system 3, the roller 201 rotates, either independently or in coordination with the swing arm 1033, to complete the raising and lowering of the curtain 202. The curtain 202 simultaneously presents a suitable posture, including sitting, sitting, and squatting positions, as well as transitions between these positions, thereby assisting the user in changing postures, including standing and sitting, and sitting and squatting. Specifically, the power system 3 is controlled by the control system. Driven by the power system 3, the "soft" raising and lowering (rolling up and releasing) of the curtain 202 and the "hard" raising and lowering of the swing arm 1033 work together to present the curtain 202 in the following manner: Figure 4 , Figure 5 , Figure 6 , Figure 7 The states shown and the transitions between states ( Figure 4 , Figure 5 , Figure 6 , Figure 7 This is the present invention. Figure 1 The working state of the illustrated embodiment differs structurally from other nursing supports covered by this disclosure, including other embodiments of this disclosure, but they all possess the same essential technical features (hence the description is used here). The transitions between corresponding states can achieve corresponding changes in body position, specifically including:

[0041] like Figure 4 The curtain 202 shown is now rolled up, and the nursing support is folded up.

[0042] like Figure 4Turn to Figure 5 The curtain 202 shown is rolled up to form a slanted support surface, suitable for "sitting in preparation";

[0043] like Figure 5 Turn to Figure 6 The slanted support surface of the curtain 202 shown is transformed into an "L" shape, which is suitable for "turning from standing to sitting";

[0044] on the contrary, Figure 6 change Figure 5 The "L" shaped surface is transformed into a sloping support surface, which is suitable for "turning from sitting to standing";

[0045] like Figure 6 The "L"-shaped surface shown is suitable for sitting.

[0046] like Figure 6 Turn to Figure 7 The curtain 202 shown has its "L" shaped surface transformed into a "V" shaped surface, making it suitable for "changing from a sitting to a squatting posture";

[0047] on the contrary, Figure 7 change Figure 6 The "V" shaped surface is transformed into an "L" shaped surface, which is suitable for "changing from a squatting posture to a sitting posture";

[0048] like Figure 5 Turn to Figure 4 The curtain 202 shown here changes from a slanted support surface to a roll-up surface, and the nursing support is folded up;

[0049] Since "reliance" refers to the user's body relying on the curtain 202 when using this nursing support in standing, sitting, or squatting positions, or during the process of changing between standing, sitting, or squatting positions, "reliance" can increase the user's safety and comfort experience when using the nursing support, and usually accompanies the entire process of use, it will not be elaborated on further below.

[0050] It is precisely this linkage structure and the combination of "soft" and "hard" that enables this nursing support to achieve superior folding and unfolding (folding and unfolding) and operational effects. Of course, this also requires consideration of the setup of the various components or parts of the nursing support, the operation of the mechanism, and the avoidance of conflicts between the nursing support and the usage environment, based on the usage needs. The setup includes the number, shape, size, and interconnection of the components or parts (including connection methods and connection positions). On this basis, the nursing support can be optimized or modified; specific embodiments are further explained below.

[0051] Based on the above description of the states exhibited during the operation of the nursing support and the transitions between these states, it can be seen that the reel 201 is installed on the upper part of the support system 1, specifically installed as follows: Figure 1The top of the first support 101 is shown, so that, on the one hand, when the support system 1 is unfolded, the reel 201 is located obliquely above the swing lever 1033, and the high-low staggered unfolding of the curtain fabric 202 is like an angle-adjustable recliner, which is conducive to the load bearing of the curtain fabric 202 on the user's body when the nursing support is in use, and on the other hand, the first support 101 is hinged to the swing support 103, and the hinge rotation is controlled by the power system 3, and in addition, the rotation of the reel 201 is also controlled by the power system 3, so that the state of the curtain fabric 202 is controllable, such as installing the reel 201 on the swing lever 1033, and the other end of the curtain fabric 202 is fixed by a pull rod arranged at the position of the original reel 201. Figure 1 The top of the second U-shaped support 102 is shown, and due to the positional relationship between the second U-shaped support 102 and the swing support 103, which is not completely controlled by the power system 3 (see the "nursing support two" section below), the state of the curtain fabric 202 will be out of control, thereby interfering with the smooth operation of the nursing support;

[0052] On the contrary, if the positions of the reel 201 and the swing lever 1033 are interchanged, i.e. the reel 201 is installed on the swing lever 1033, and a pull rod is additionally arranged at the position of the original reel 201 to fix the other end of the curtain fabric 202, although the above two advantages still exist, the user's experience is obviously different, because: when "sitting to standing", the reel 201 winds the curtain fabric 202, and the user sitting on the curtain fabric 202 will move the hips forward with the curtain fabric 202 due to the existence of friction, and the phenomenon that the user's hips move out of the load bearing surface of the curtain fabric 202 before standing up may occur, so there is a risk of the user falling; at the same time, when "standing to sitting", the user's body will also move too far backward with the curtain fabric 202 due to the existence of friction, which is embarrassing; moreover, there is a safety hazard that the skin and clothes are wound into the reel 201, of course, in order to eliminate the hazard, the problem can be solved by moving the reel 201 backward and making the curtain fabric 202 pass through the swing lever 1033 (a roller is additionally arranged on the swing lever 1033), but in this way, on the one hand, the structure becomes complex, and on the other hand, the space occupied by the reel 201 and the driving device of the reel will be significantly increased, and conflicts with adjacent components or the surrounding environment are easy to occur during use; therefore, this scheme should be used with caution unless there is a special need;

[0053] In order to adapt to different use requirements, the present application can also be combined with other technical features that can enrich the use experience of the present application without conflict, these technical features include: functional holes are arranged on the curtain fabric 202 and / or additional functional modules are arranged, handrails 106 are arranged, supporting legs 108 are installed to realize movable use of the nursing support, a protective shell 203 is arranged outside the reel 201 to prevent foreign matters from being wound into the reel 201, etc.

[0054] Similarly, in order to adapt to different use requirements, the technical features of the present application can also be optimized or varied or replaced without exceeding the scope of protection of the present application and without conflict, such as Figure 1 、 Figure 8The swing frame 103 shown can be modified into a "T" shape or a regular "kitchen spatula" shape (with the larger end of the "T" or "kitchen spatula" at the front) when the nursing support is only used for rehabilitation training involving changes in body position. Correspondingly, the power device driving the swing frame 103 needs to be adjusted (to...). Figure 1 For example, as long as one electric actuator 301 is connected to the tail of the swing frame 103 in the middle of the nursing support, such optimization or modification can simplify the structure of the nursing support and reduce costs; for another example... Figure 1 , Figure 8 The power system 3 shown includes an electric actuator 301 and a motor 302. The electric actuator 301 drives the swing frame 103 to reciprocate up and down swinging motion, and the motor 302 drives the scroll 201 to rotate. Power devices suitable for driving the swing frame 103 to reciprocate up and down motion and driving the scroll 201 to rotate include transmission devices and various other types, all of which can be used to construct the power system 3 of the present invention.

[0055] Not only the swing frame 103 and the power system 3, but also the various subsystems of the nursing support have different construction (optimization, modification or replacement) methods, and the subsystems can be configured according to the needs of use. There are also many configuration schemes. Regardless of the construction method or configuration scheme, as long as it can help the roller 201 and the swing rod 1033 coordinate to realize the state and change of the curtain 202 described in this embodiment, while avoiding conflicts, it can help the user complete the position change, solve the problems existing in the prior art, and achieve the beneficial effects of the present invention.

[0056] Clearly, this invention has the characteristics of being fully functional and having an outstanding retraction and extension effect;

[0057] The following section will further elaborate on the construction method or configuration scheme of the nursing stent subsystem.

[0058] Preferably, both the swing frame 103 and the first support 101 are U-shaped. The swing arm includes a first swing arm 1031 and a second swing arm 1032. The swing rod 1033 is fixedly connected to the first end of the first swing arm 1031 and the second swing arm 1032. The first support 101 includes a first support arm 1011, a second support arm 1012 and a third support arm 1013 fixedly connected between the two. The first swing arm 1031 and the second swing arm 1032 are respectively hinged to the first support arm 1011 and the second support arm 1012.

[0059] Specifically, such as Figure 8 As shown, the first swing arm 1031 and the second swing arm 1032 are hinged to the first support arm 1011 and the second support arm 1012 respectively, providing a fulcrum for the swing of the swing frame 103. Under the drive of the power system 3, the swing arm 1033 swings up and down with the swing frame 103.

[0060] One of the use scenarios of the present application is combined with the use of a toilet, so the care support cannot conflict with the toilet, including not affecting the normal use of the toilet, the application of the U-shaped support in the support system 1 is just for this purpose, for example, the setting of the swing bracket 103, both to meet the conflict with the care support itself when folding and unfolding, and to meet the conflict with the toilet when combined with the toilet; Specifically: to avoid the conflict between the swing bracket 103 and the care support itself, the height of the swing lever 1033 of the swing bracket 103 when it is in the upright state should be lower than the height of the reel 201; In order to avoid the conflict between the swing bracket 103 and the toilet, the swing bracket 103 is made into a U-shaped first swing arm 1031 and a second swing arm 1032, only the first end has a swing lever 1033, the inner diameter of the swing bracket 103 is larger than the outer diameter of the seat and cover of the toilet, and the height of the swing lever 1033 when the swing bracket 103 is in the upright state is not lower than the height of the seat and cover of the toilet in the upright state, so that the swing bracket 103 can realize the normal use of the seat and cover of the toilet without affecting the normal use of the seat and cover of the toilet;

[0061] Obviously, if the care support is only used in an accessible environment, the strength of the swing bracket 103 can be strengthened by adding a connecting rod between the two swing arms of the U-shaped swing bracket 103, thereby improving the stability of the care support; In addition, the description of "U" is only for convenience of description and understanding, and "U" should not be imagined as a fixed shape, for example, Figure 1 、 Figure 8 The shape of the U-shaped swing bracket 103 and the first support 101 shown in Figure 4 is not the same, the first swing arm 1031 and the second swing arm 1032 of the U-shaped swing bracket 103 are bent at the hinge with the first arm 1011 and the second arm 1012, this optimization and modification can obtain better folding and unfolding effect, as shown in Figure 4 , and can also avoid the phenomenon of jamming due to the too small transmission angle of the transmission connection between the tail of the swing arm of the swing bracket 103 and the output end of the electric push rod 301, and at the same time, it also cooperates with the linkage of the support to achieve the action of the swing lever 1033 of the care support in the first and second supports swinging up and down with the front and rear moving (which will be described in the "sitting down" example below), the first support 101 does not need to imitate this;

[0062] Preferably, in order to enable users to obtain a more comprehensive use experience, according to the use needs, functional holes and / or additional functional modules are provided on the curtain cloth 202;

[0063] Specifically, the functional holes include holes for defecation and sanitary cleaning as shown in Figure 1 , the additional functional modules include modules with functions of supporting, covering, collecting excrement, heating, sterilizing, ventilating, cleaning, assisting physical examination and treatment, and monitoring signs, and the additional mode can be fixed or detachable;

[0064] The support module provides additional support for the curtain 202, focusing on supporting the "seat" section (the position where the user sits). This not only keeps the curtain 202 flat and well-shaped but also improves the product's versatility. Especially when the curtain 202 lacks support similar to a toilet seat, a support module with essentially the same function as a toilet seat can be added to the "seat" section of the curtain 202. The covering module is used to cover the functional holes on the curtain 202, allowing the curtain 202 to switch freely between having and not having functional holes, achieving multiple uses in one device. Of course, this invention can also meet different usage needs by replacing the curtain 202 or configuring different curtains 202.

[0065] For the proper use and folding of the nursing support, the additional functional module must not affect the bending between the "seat section" and "backrest section" of the curtain 202, or between the "seat section" and the swing rod 1033. When the additional functional module is not suitable for being rolled up by the roller 201, the solutions are: 1. The functional module is detachable and can be removed when not in use; 2. Without affecting the rollability of the "backrest section" curtain, the roller 201 and the swing rod 1033 can be used in combination. For ease of description and understanding, the specific implementation methods are described in the embodiments of the nursing support usage method below.

[0066] Preferably, the power system 3 includes an electric actuator 301 and a motor 302. The electric actuator 301 is connected to the swing frame 103 for transmission, driving the swing frame 103 to reciprocate up and down swinging. The swing arm 1033 swings up and down with the swing frame 103. The motor 302 is connected to the reel 201 for transmission. Preferably, the motor 302 is connected to the reel 201 for gear transmission.

[0067] The wide market availability of electric actuator 301 and motor 302 facilitates product diversification and cost control; specifically, such as Figure 8 As shown, the middle parts of the first arm 1011 and the second arm 1012 are respectively hinged to the middle parts of the first swing arm 1031 and the second swing arm 1032. The output ends of the two electric actuators 301 are respectively hinged to the tail ends of the first swing arm 1031 and the second swing arm 1032. The tail parts of the two electric actuators 301 are respectively hinged to the first arm 1011 and the second arm 1012. The reel 201 is connected to the motor 302 by gear transmission and is installed on the top of the first bracket 101.

[0068] When in use, use the first bracket 101 as the mounting frame to install the nursing bracket on the wall, the ground or other reliable object. The usage method is described in detail in the following section.

[0069] This embodiment illustrates one of the basic architectures of a nursing stent. For ease of description, this nursing stent will be referred to as "Nursing Stent One".

[0070] Obviously, according to the lever principle, changing the swing pivot of the swing frame 103 and the access point of the output end of the electric push rod 301 can obtain an equivalent alternative of the above technical solution: the tail end of the first swing arm 1031 and the second swing arm 1032 are respectively hinged to the middle part of the first branch arm 1011 and the second branch arm 1012, and the output end of the two electric push rods 301 are respectively hinged to the middle part of the first swing arm 1031 and the second swing arm 1032.

[0071] Preferably, on the basis of "nursing support one", the support system 1 further comprises a second U-shaped support 102, a connecting plate 104 and a folding rod 105; the second U-shaped support 102 comprises a fourth branch arm 1021, a fifth branch arm 1022 and a sixth branch arm 1023 fixedly connected between the two; wherein the first branch arm 1011 and the fourth branch arm 1021 and the second branch arm 1012 and the fifth branch arm 1022 are respectively hinged to the head end and the tail end of the two connecting plates 104, the tail end of the two folding rods 105 are respectively hinged or slidably connected to the fourth branch arm 1021 and the fifth branch arm 1022, the head end of the two folding rods 105 are respectively hinged to the tail of the first swing arm 1031 and the second swing arm 1032, the bottom end of the first branch arm 1011 and the second branch arm 1012 are both installed with a pulley 1014, and the tail of the two electric push rods 301 are respectively hinged to the first branch arm 1011 and the second branch arm 1012 or respectively hinged to the fourth branch arm 1021 and the fifth branch arm 1022;

[0072] Specifically, as shown in Figure 1 the tail of the two electric push rods 301 are respectively hinged to the fourth branch arm 1021 and the fifth branch arm 1022, and the tail end of the two folding rods 105 are respectively hinged to the fourth branch arm 1021 and the fifth branch arm 1022;

[0073] The specific way of the tail end of the folding rod 105 slidingly connecting with the fourth branch arm 1021 and the fifth branch arm 1022 can be that a guide rail is arranged on the fourth branch arm 1021 and the fifth branch arm 1022, a sliding block is adapted to the guide rail, the guide rail and the sliding block are slidingly connected, the tail end of the first swing arm 1031 and the tail end of the second swing arm 1032 are respectively hinged with two folding rods 105 (at this time, the folding rod 105 is equivalent to a connecting part, preferably a short distance connection), and the tail end of the folding rod 105 is fixedly connected with the sliding block. Obviously, according to the principle of the lever, the swing support point of the swing frame 103 can be moved from the first support frame 101 to the second U-shaped support frame 102 (that is, the tail end of the first swing arm 1031 and the tail end of the second swing arm 1032 are respectively hinged with the fourth branch arm 1021 and the fifth branch arm 1022), the sliding pair on the fourth branch arm 1021 and the fifth branch arm 1022 is moved to the first branch arm 1011 and the second branch arm 1012, the middle part of the first swing arm 1031 and the middle part of the second swing arm 1032 are respectively connected with the output ends of the two electric push rods 301 (at this time, the folding rod 105 is equivalent to a general connecting part), and the rest remains unchanged. The changed scheme can still solve the same technical problems and obtain the same technical effects as the above-mentioned embodiments.

[0074] Compared with the hinged connection and the sliding connection of the folding rod 105 with the fourth branch arm 1021 and the fifth branch arm 1022, the former has the characteristic of the scissors structure, the scissors can be stacked, and the latter has good stability of the sliding pair and saves space.

[0075] Compared with the two connection positions of the tail end of the electric push rod 301, when the electric push rod 301 is connected to the first branch arm 1011 and the second branch arm 1012, the forces from the ground, the swing frame 103, the electric push rod 301 and the curtain fabric 202 on the first branch arm 1011 and the second branch arm 1012 have a mutual balancing effect, when the electric push rod 301 is connected to the fourth branch arm 1021 and the fifth branch arm 1022, the electric push rod 301 transfers the pushing force of the former on the first branch arm 1011 and the second branch arm 1012 to the second U-shaped support frame 102, and disperses the force of the former concentrated on the first support frame 101, so that the former has better stability, but if the first branch arm 1011 and the second branch arm 1012 do not touch the ground (the "nursing support three" will be described below), the advantage will not exist.

[0076] Since the first support frame 101 bears most of the load of the nursing support, the bottom end of the first branch arm 1011 and the second branch arm 1012 touching the ground helps the stability of the nursing support, in order to cooperate with the smooth folding and unfolding of the nursing support, a pulley 1014 is installed at the bottom end of the first branch arm 1011 and the second branch arm 1012, of course, the pulley 1014 can be replaced by other sliding devices with the same effect;

[0077] In use, the second U-shaped support 102 is used as a mounting rack, and the nursing support is mounted on a wall, the ground or other reliable objects. The specific mounting method is described below.

[0078] For the convenience of description, the nursing support is referred to as "nursing support two".

[0079] Compared with the "nursing support one", the "nursing support two" has the second U-shaped support 102, the connecting plate 104 and the folding rod 105, so that the folding and unfolding effects and applicability of the nursing support are improved.

[0080] Preferably, on the basis of the "nursing support two", the two connecting plates 104 are provided with limiting parts 107 near the hinge shafts of the fourth arm 1021 and the fifth arm 1022, the limiting parts 107 are used to limit the downward rotation of the connecting plates 104 around the hinge shafts, or the hinge connection of the two connecting plates 104 with the fourth arm 1021 and the fifth arm 1022 is changed to fixed connection, and the bottom of the first support 101 is not in contact with the bottom surface, and the rest remains unchanged, as shown in Figure 9 .

[0081] In the embodiment, the purpose of the limiting hinge or fixed connection is to make the swing of the swing support 103 still have a reliable fulcrum when the bottom ends of the first arm 1011 and the second arm 1012 are not in contact with the ground. The included angle between the connecting plate 104 and the fourth arm 1021 and the fifth arm 1022 after the limiting angle or fixed connection is set to be conducive to the folding and unfolding of the multi-link mechanism, and is preferably equal to 90 degrees.

[0082] In use, the second U-shaped support 102 is used as a mounting rack, and the nursing support is mounted on a wall, the ground or other reliable objects.

[0083] For the convenience of description, the nursing support is referred to as "nursing support three".

[0084] Compared with the "nursing support two", the "nursing support three" has less ground contact support of the first support 101, so that the mounting rack of the "nursing support three" bears more stress, has slightly poor stability, has higher installation requirements, has similar folding and unfolding effects, and has smaller ground occupation space.

[0085] Optionally, on the basis of the "nursing support three", the connection mode of the two ends of the connecting plate 104 with the first arm 1011, the second arm 1012, the fourth arm 1021 and the fifth arm 1022 is changed from hinge connection to fixed connection, the folding rod 105 is cancelled, and whether the two arms of the first support are in contact with the ground is not limited, and the rest remains unchanged.

[0086] For the convenience of description, the nursing support is referred to as "nursing support four".

[0087] Since the connection mode of the connecting plate 104 at both ends to the first branch arm 1011, the second branch arm 1012, the fourth branch arm 1021 and the fifth branch arm 1022 in the fourth nursing support is changed from hinged to fixed connection, the folding rod 105 is cancelled, and the first support 101 and the second U-shaped support 102 become one, at this time, the fourth nursing support is equivalent to the first nursing support, and the second U-shaped support 102 in the fourth nursing support can be used as the mounting part of the first nursing support or part of the mounting rack. When used, the first support 101 and / or the second U-shaped support 102 can be used as the mounting rack, and the bottom end of the support arm without the mounting rack is not limited to whether it touches the ground. Only the more fixed points or support points of the mounting rack, the better the stability.
