Description

Technical Field

[0001] The present invention belongs to the field of toilet equipment, and in particular to a toilet auxiliary device and a use method thereof. Background Art

[0002] In the context of an aging society, the proportion of elderly people is increasing. Many families choose to spend money to place their elderly in nursing homes for professional care. Some elderly people cannot accept living in nursing homes and choose to live alone. However, due to the limited physical activities of the elderly, they cannot do various things like ordinary people. For example, when going to the toilet, many elderly people with mobility problems even have difficulty squatting, and some elderly people are unable to stand up after squatting or sitting down. If an elderly person who falls while using the toilet does not have the help of outsiders, it is likely that he will not be able to stand up on his own, resulting in accidental falls and casualties. Nowadays, there are targeted call systems for using the toilet, as well as handrails on both sides to provide leverage for the elderly or people with mobility problems. However, the call system is a remedial measure after an accident, and the leverage of the handrails also depends on the person's own strength, which cannot effectively reduce the burden of squatting and sitting on the toilet for the elderly. Summary of the Invention

[0003] The purpose of the present invention is to improve the shortcomings of the prior art and provide a toilet assisting device and a method of using the same, which assists toilet users in sitting, squatting and standing by using external force.

[0004] The technical solution is as follows:

[0005] The toilet assist device includes a first support member, a second support member, a third support member, a fourth support member and a driving member. A receiving seat is installed on the first support member. The first support member is rotatably connected to the second support member and the fourth support member respectively. The third support member is rotatably connected to the other end of the second support member and the fourth support member respectively; the driving member acts on any two of the first support member, the second support member, the third support member and the fourth support member.

[0006] In one embodiment, the driving member is rotatably mounted on the third support member and the fourth support member.

[0007] In one embodiment, the driving member is a linear drive, and two active ends are rotatably mounted on the third support member and the fourth support member respectively.

[0008] In one embodiment, the receiving seat includes a power mechanism and two clamping seats, the power mechanism is installed on the first supporting seat, the clamping seats are installed symmetrically, and the power mechanism cooperates with the clamping seats.

[0009] In one embodiment, the power mechanism includes a power motor, a first rack, a second rack and a power gear. The power gear is fixedly mounted on the output shaft of the power motor. The first rack and the second rack are respectively mounted on each of the card seats. The first rack and the second rack are respectively located on both sides of the power gear and mesh with the power gear.

[0010] In one embodiment, the card seat includes a bracket body and a pad, the bracket body is slidingly matched with the first support member, the first rack or the second rack is installed on the bracket body, and the pad is installed on the bracket body, and the pad protrudes outward.

[0011] In one embodiment, a camera is further mounted on the first support member, and the camera is located between the two card seats.

[0012] In one embodiment, the first support member includes a main frame and an outward-convex support rod, the outward-convex support rod and the receiving seat are mounted on the main frame, and the second support member and the fourth support member are rotatably mounted on the outward-convex support rod.

[0013] In one embodiment, it further includes a lifting mechanism and an adjusting rod, wherein the lifting mechanism is slidably mounted on the fourth support member, and one end of the adjusting rod is rotatably connected to the first support member, and the other end is rotatably connected to the lifting mechanism.

[0014] The steps for using a toileting aid include:

[0015] Before use, the first support member, the second support member, the third support member, and the fourth support member are folded together;

[0016] The user stands close to the toilet assistive device, places both hands on the receiving seat, and begins to squat. The toilet assistive device detects that the user is squatting, and the driving member drives the first support member, the second support member, the third support member, and the fourth support member to unfold.

[0017] When the user squats, the first support member, the second support member, the third support member, and the fourth support member are gradually unfolded, and finally the user is in a sitting and squatting state, and the first support member, the second support member, the third support member, and the fourth support member are unfolded to a use state;

[0018] After the user has finished using the toilet, he or she starts to stand up. The toilet assistive device detects that the user is standing up, and the driving member drives the first support member, the second support member, the third support member, and the fourth support member to retract, causing the receiving seat to lift up, clamp the armpit of the human body, and start to assist the user to stand up;

[0019] The user stands up and toilet assistance is completed.

[0020] The technical solution provided by the present invention has the following advantages and effects:

[0021] 1. The first, second, third, and fourth supports are connected end to end, and the lines connecting the connections form a four-bar linkage that can achieve folding and unfolding. The driver acts on the first, second, third, and fourth supports. When the driver performs a first action, the first, second, third, and fourth supports are moved closer together to form a folded state, at which point the user is standing. When a user approaches the toilet assist device and places their hands on the receiving seat, and the user begins to squat or sit, the toilet assist device detects this and then the driver performs a second action, causing the first, second, third, and fourth supports to begin to unfold. The user also begins to squat or sit, and during this process, the user and the toilet assist device move downward together to complete the squatting or sitting. When the user needs to stand, the driver performs a first action, causing the first, second, third, and fourth supports to move closer together. At this time, the receiving seat drives the user upward, i.e., the user is driven to stand by an external force. It effectively avoids falling due to inability to stand up when using the toilet.

[0022] 2. When in the standing state, the clamping claw is downward and in the first position; when in the squatting or sitting state, the clamping claw is to the left and in the second position. The first position is higher than the second position. At this time, the adjustment rod cleverly utilizes the cooperation relationship between the first support member, the second support member, the third support member and the fourth support member to drive the up and down movement of the pulling assembly, and also adjusts the direction of the clamping claw to conform to the user's pants clamping. If the direction of the clamping claw is not adjusted, the orientation of the pants will change due to the user's standing and squatting states. Therefore, if the clamping claw is only in the same direction at this time, the pants will be twisted, affecting the user's experience of pulling up the pants. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Unless stated otherwise or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0040] It should be noted that when an element is considered to be "fixed to" another element, it can be directly fixed to the other element or there can be an intermediate element; when an element is considered to be "connected to" another element, it can be directly connected to the other element or there can be an intermediate element; when an element is considered to be "mounted on" another element, it can be directly mounted on the other element or there can be an intermediate element. When an element is considered to be "located on" another element, it can be directly located on the other element or there can be an intermediate element.

[0041] like Figures 1 to 5 As shown, the toilet assist device includes a first support member 10, a second support member 20, a third support member 30, a fourth support member 40 and a driving member 50. A receiving seat 11 is installed on the first support member 10. The first support member 10 is rotatably connected to the second support member 20 and the fourth support member 40 respectively. The third support member 30 is rotatably connected to the other end of the second support member 20 and the fourth support member 40 respectively; the driving member 50 acts on any two of the first support member 10, the second support member 20, the third support member 30 and the fourth support member 40.

[0042] The first support member 10, the second support member 20, the third support member 30, and the fourth support member 40 are connected end to end, and the connection lines at the connection points form a four-bar linkage mechanism, which can realize folding and unfolding. The driving member 50 acts on the first support member 10, the second support member 20, the third support member 30, and the fourth support member 40. When the driving member 50 performs the first action, the first support member 10, the second support member 20, the third support member 30, and the fourth support member 40 are brought close to each other in a folded state, that is, Figure 1 and Figure 2The user approaches the toilet assistive device and places his hand on the receiving seat 11. When the user begins to squat or sit, the toilet assistive device detects it, and then the driving member 50 performs the second action, causing the first support member 10, the second support member 20, the third support member 30 and the fourth support member 40 to begin to unfold. The user also begins to squat or sit. During the process, the user and the toilet assistive device move downward together to complete squatting or sitting. Figure 4 and Figure 5 When the user needs to stand, the driver 50 performs a first action, causing the first support member 10, the second support member 20, the third support member 30, and the fourth support member 40 to move closer to each other. At this time, the receiving seat 11 drives the user upward, i.e., the user is forced to stand up by external force. This effectively prevents the user from falling due to inability to stand while using the toilet.

[0043] like Figures 1 to 5 As shown, the driving member 50 is rotatably mounted on the third support member 30 and the fourth support member 40. The first movement of the driving member 50 is an extension state, and the second movement is a contraction state. Specifically, the extension and contraction of the driving member 50 drive the rotation between the third support member 30 and the fourth support member 40, thereby achieving the expansion and folding of the first support member 10, the second support member 20, the third support member 30, and the fourth support member 40.

[0044] The driving member 50 is a linear driver 51, and its two active ends are respectively rotatably mounted on the third support member 30 and the fourth support member 40. The third support member 30 and the fourth support member 40 are controlled by extension and contraction.

[0045] like Figures 1 to 3 As shown, the receiving base 11 includes a power mechanism 12 and two clamping seats 13. The power mechanism 12 is installed on the first supporting base, and the clamping seats 13 are installed symmetrically. The power mechanism 12 cooperates with the clamping seats 13. At this time, the power mechanism 12 is used to drive the movement of the two clamping seats 13 and adjust the positions of the two clamping seats 13 to meet the needs of different users.

[0046] like Figure 6As shown, the power mechanism 12 includes a power motor 123, a first rack 121, a second rack 122 and a power gear 124. The power gear 124 is fixedly mounted on the output shaft of the power motor 123. The first rack 121 and the second rack 122 are respectively mounted on each of the card holders 13. The first rack 121 and the second rack 122 are respectively located on both sides of the power gear 124 and mesh with the power gear 124. At this time, the power motor 123 rotates to drive the linear motion between the first rack 121 and the second rack 122. The first rack 121 and the second rack 122 are respectively located on the two card holders 13, so as to drive the motion between the two card holders 13. The cooperation between the first rack 121 and the second rack 122 and the power gear 124 causes the first rack 121 and the second rack 122 to move in two states: approaching each other and moving away from each other.

[0047] like Figure 6 As shown, the card holder 13 includes a bracket body 131 and a pad 132. The bracket body 131 is slidably engaged with the first support member 10. The first rack 121 or the second rack 122 is mounted on the bracket body 131. The pad 132 is mounted on the bracket body 131 and protrudes outward. The bracket body 131 serves to connect the first rack 121 or the second rack 122 and the pad 132. The pad 132 is the part that supports the user, so this part requires more personalized settings. Therefore, separate pads 132 are provided for different users.

[0048] like Figure 6 As shown, a camera 14 is further mounted on the first support member 10 and is located between the two holders 13. The camera 14 captures the user's movements. When the user moves downward, the camera 14 captures the image and then transmits the image information to the processor, which issues instructions for controlling the movement of the driving member 50.

[0049] like Figures 1 to 5 As shown, the first support member 10 includes a main frame 15 and a protruding support rod 16. The protruding support rod 16 and the receiving seat 11 are mounted on the main frame 15, and the second support member 20 and the fourth support member 40 are rotatably mounted on the protruding support rod 16. The main frame 15 is used to mount the receiving seat 11, and the rotatable connection between the protruding support rod 16 and the second support member 20 and the fourth support member 40 can play an avoidance role when the first support member 10, the second support member 20, the third support member 30 and the fourth support member 40 cooperate, thereby preventing the situation where the first support member 10, the second support member 20, the third support member 30 and the fourth support member 40 cannot be folded.

[0050] like Figures 4 to 7As shown, the toilet assistive device further includes a lifting mechanism 70 and an adjusting rod 60. The lifting mechanism 70 is slidably mounted on the fourth support member 40. One end of the adjusting rod 60 is rotatably connected to the first support member 10, and the other end is rotatably connected to the lifting mechanism 70. The lifting mechanism 70 is used to lift the trousers. When the first support member 10, the second support member 20, the third support member 30, and the fourth support member 40 are folded, one end of the adjusting rod 60 is rotatably connected to the first support member 10. Therefore, when the other end is rotatably connected to the lifting mechanism 70, the positional relationship between the first support member 10, the second support member 20, the third support member 30, and the fourth support member 40 changes, causing the position of the adjusting rod 60 to change and the lifting mechanism 70 to slide on the fourth support rod, thereby driving the lifted trousers to move downward.

[0051] like Figure 7 As shown, the lifting mechanism 70 includes a clamping assembly and an extension assembly. The extension assembly includes an extension power member 741 and an extension seat 742. The extension power member 741 drives the extension seat 742 to perform an outward reciprocating motion. The clamping assembly is mounted on the extension seat 742 and includes a clamping claw that protrudes from the extension seat 742. The clamping assembly is used to clamp the trousers, while the extension assembly is used to control the extension and retraction of the clamping assembly. The extension seat 742 is moved outward by the extension power member 741 so that the clamping claw can grasp the trousers.

[0052] like Figure 1 As shown, when in the standing state, the clamping claw is downward and in the first position, as shown in FIG. Figure 4 As shown, when in a squatting or sitting state, the clamping claw is to the left and is in the second position, and the first position is higher than the second position. At this time, the adjusting rod 60 cleverly utilizes the cooperation relationship between the first support member 10, the second support member 20, the third support member 30 and the fourth support member 40 to drive the up and down movement of the pulling assembly, and also adjusts the direction of the clamping claw to conform to the user's pants clamping. If the direction of the clamping claw is not adjusted, the orientation of the pants will change due to the user's standing and squatting states. Therefore, if the clamping claw is only in the same direction at this time, the pants will be twisted, affecting the user's experience of pulling up the pants.

[0053] like Figures 7 to 9As shown, the extension power member 741 includes an extension motor 7411, an extension gear 7412, an extension rack 7413, and a fixed base 7414. The extension motor 7411 is fixedly mounted on the extension base 742 or the fixed base 7414. The extension gear 7412 is fixedly mounted on the output shaft of the extension motor 7411. The extension rack 7413 is mounted between the fixed base 7414 and the extension base 742, and the extension gear 7412 is meshed with the extension rack 7413. The extension motor 7411 converts the rotational motion between the extension rack 7413 into linear motion, thereby driving the extension base 742 to move outward.

[0054] Specifically, the outward motor 7411 is fixedly mounted on the outward seat 742 , and one end of the outward rack 7413 is fixedly mounted on the fixed seat 7414 and the other end movably extends into the outward seat 742 .

[0055] like Figure 8 and Figure 9 As shown, the extension assembly further includes a guide rod 743, which is fixedly mounted on a fixing seat 7414, and the other end of which is slidably engaged with the extension seat 742. Guided by the guide rod 743, the movement accuracy of the extension assembly is higher.

[0056] like Figures 7 to 9 As shown, the clamping assembly includes a clamping seat 711, the clamping seat 711 is mounted on the overhanging seat 742, and the clamping claw is provided on the clamping seat 711. The clamping claw is relatively fixed to the clamping seat 711 and moves with the clamping seat 711.

[0057] like Figures 7 to 9 As shown, the clamping assembly further includes a movable claw 72 and a control member 73. The movable claw 72 is rotatably mounted on the clamping seat 711 and cooperates with the clamping claw. The control member 73 cooperates with the movable claw 72 and drives the movable claw 72 to rotate. The movable claw 72 rotates relative to the clamping seat 711. The rotation of the movable claw 72 is controlled by the control member 73. When the movable claw 72 is controlled to rotate to the clamping claw, the trousers can be clamped.

[0058] like Figure 8 and Figure 9 As shown, the control member 73 includes a sliding block 733, which is provided with linearly arranged teeth and is slidably mounted on the clamping seat 711. The outer side of the end of the movable claw 72 that rotates with the clamping seat 711 is provided with circumferentially arranged teeth. The sliding member engages with these teeth to drive the movable claw 72 to rotate. At this time, the linear movement of the sliding block 733 is used to control the rotation of the movable claw 72.

[0059] Specifically, if Figure 8 and Figure 9 As shown, the control member 73 further includes a first rotating block 731 and a second rotating block 732. One end of the first rotating block 731 is rotatably connected to the sliding block 733, and the other end of the first rotating block 731 is rotatably connected to the second rotating block 732. The other end of the second rotating block 732 is rotatably connected to the clamping seat 711. The first rotating block 731, the second rotating block 732, and the sliding block 733 form a crank slider mechanism. The sliding block 733 slides by manually controlling the rotation between the first rotating block 731 and the second rotating block 732.

[0060] like Figure 8 and Figure 9 As shown, the first rotating block 731 and the second rotating block 732 rotate between less than 180 degrees and greater than 180 degrees. This setting means that the rotation between the first rotating block 731 and the second rotating block 732 can be turned to a parallel state, such as Figure 9 As shown, the rotation angle between the first rotating block 731 and the second rotating block 732 is greater than 180 degrees, reaching a locking angle, which cannot be released without human driving.

[0061] like Figure 7 and Figure 8 As shown, a contact switch 75 is mounted on the clamping assembly or the overhanging seat 742. Specifically, it is arranged on the clamping assembly. After the clamping assembly retracts, the contact switch 75 contacts the fourth support rod. Upon receiving the signal, the driver 50 is controlled to start folding the first support member 10, the second support member 20, the third support member 30, and the fourth support member 40.

[0062] It should be noted that the protruding seat 742 and the clamping seat 711 can be integrally provided. Specifically, in this embodiment, they are integrally provided.

[0063] The method for using the toilet assistive device includes the following steps:

[0064] Before use, the first support member 10, the second support member 20, the third support member 30, and the fourth support member 40 are folded together;

[0065] The user stands close to the toilet assistive device, places both hands on the receiving seat 11, and begins to squat. The toilet assistive device detects that the user is squatting, and the driving member 50 drives the first support member 10, the second support member 20, the third support member 30, and the fourth support member 40 to unfold;

[0066] When the user squats, the first support member 10, the second support member 20, the third support member 30, and the fourth support member 40 are gradually unfolded. Finally, the user is in a squatting state, and the first support member 10, the second support member 20, the third support member 30, and the fourth support member 40 are unfolded to a use state.

[0067] After the user has finished using the toilet, he or she starts to stand up. The toilet assist device detects that the user has stood up, and the driving member 50 drives the first support member 10, the second support member 20, the third support member 30, and the fourth support member 40 to retract, causing the receiving seat 11 to lift up, clamp the armpit of the human body, and start to assist the user to stand up.

[0068] The user stands up and toilet assistance is completed.
