Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a type of a chair-type simple toilet toilet seat lifting device, and in particular, provides a supportive force for a sick person or an elderly person to sit or stand when excreting, thereby making it easier for the sick person or the elderly to perform. The present invention relates to a device for raising and lowering a toilet seat of a chair-type simple toilet.
[0002]
[Prior art]
The chair-type restroom is a chair 10 on which a toilet is installed, which comprises a seat 11 which can be opened and closed in a rotatable manner, and a toilet 12 is left under the seat 11, as shown in FIG. The chair type toilet is used for the elderly and the sick. When the sick or elderly person does not use the chair-type simple toilet, the toilet 11 can be used as a general chair by shielding the toilet bowl 12 with the seat 11. Most of such a chair type toilet 10 is placed in a bedroom, and its appearance is not much different from a chair as general furniture, so that elderly people and patients do not have to be ashamed even in front of customers. Such a chair-type toilet is a product that is highly valued in Japan, and can be said to be furniture that needs to be deployed in homes for the elderly and the sick.
[0003]
The fact that the elderly and sick have to use the chair-type toilet indicates that their behavioral ability is reduced and their thigh support is weakened. The operation of standing up from the toilet is completed by the support force of the thigh. If the old man's thigh is helpless or the sick has an injured thigh, the person may spend his power on the movement and require the assistance of another person. However, excretion is an extremely private act, and it is the same for elderly and sick people who want to complete it alone.
[0004]

I do.
[0007]
In the toilet seat elevating device for a chair-type simple toilet provided by the present invention, the lower portion of the receiving seat is a peripheral wall corresponding to the perforated shape of the seat, and the outer wall surface of the peripheral wall is fitted with the inner edge of the perforated hole. Accordingly, during the ascending and descending process of the receiving seat, all the peripheral walls thereof are held in the perforations, so that a person or an article is not pinched and the safety is high.
[0008]
【Example】
As shown in FIGS. 2 and 3, the chair type simple toilet 20 provided by the present invention has a chair type simple toilet 20 in which a chair body 21, a toilet 22, a receiving seat 23 holding the toilet 22, and a chair. A drive mechanism 30 provided inside the main body 21 is provided. A large hole 211 is provided in the chair body 21 at a position where a person sits. The receiving seat 23 is installed at a position where the chair body 21 sits, and shields the perforation 211 of the chair body 21. The toilet 22 is held at the center of the upper surface of the receiving seat 23. The drive mechanism 30 includes a lower frame 31 fixed to the chair body 21, an upper frame 32 fixed to the receiving seat 23, two U-shaped rods 33 and 34 pivotally connected so that the side bars cross each other, and an electric motor. A telescopic tube mechanism 35 is provided. The lower ends of the first U-shaped rod 33 are pivotally connected to the rear end of the lower frame 31, and the upper ends of the two side bars 331 are pivotally mounted on rollers 332 that move on the guide rails 321 on both sides of the upper frame 32, respectively. This is as shown in FIG. Both lower ends of the second U-shaped rod 34 are pivotally mounted on rollers 342 that move on the guide rails 311 on both sides of the lower frame 31, and upper ends of the side bars 341 on both sides are pivotally connected to the rear end of the upper frame 32. . One end of the telescopic tube mechanism 35 is a base sheet 351, and the other end is a telescopic tube 352 that expands and contracts. The base sheet 351 is pivotally connected to the rear end of the lower frame 31, and the outer end of the telescopic tube 352 is pivotally connected to the bottom of the second U-shaped rod 34. When the telescopic tube 352 of the telescopic tube mechanism 35 performs the inward contraction operation, the lower end of the second U-shaped rod 34 is driven to approach rearward, and the lower ends of the two U-shaped rods 33 and 34 approach each other. The upper ends of the side bars 331, 341 on both sides of the shaped rods 33, 34 are raised, whereby the upper frame 32 is raised, and thereby the receiving seat 23 is raised.
[0009]
As described above, when the telescopic tube 352 of the telescopic tube mechanism 35 extends outward, the rollers 342 on both ends of the telescopic tube 352 of the second U-shaped rod 34 move forward along the guide rails 311 on both sides of the lower frame 31. I do. At the same time, the rollers 332 at the upper ends of the side bars 331 on both sides of the first U-shaped rod 33 move forward along the guide rails 321 on both sides of the upper frame 32, thereby lowering the upper frame 32. As shown in FIGS. When the telescopic tube 352 of the telescopic tube mechanism 35 contracts inward, the rollers 342 on both lower ends of the second U-shaped rod 34 move rearward along the guide rails 311 on both sides of the lower frame 31, and at the same time, the first U-shaped rod 33 The rollers 332 at the upper ends of the side bars 331 on both sides of the upper frame 32 move rearward along the guide rails 321 on both sides of the upper frame 32, thereby raising the upper frame 32, as shown in FIG. The seat 23 rises, as shown in FIG.
[0010]
When the person with weakened support of the thighs excretes using the above-mentioned simple toilet 20, if the receiver 23 is raised first to reach the state shown in FIG. The seat 23 can be seated, and most of the body weight can be supported by the seat 23. Further, in the process of lowering the receiving seat 23, the weight of the user is supported by the receiving seat 23, and the user can easily sit on the thigh without applying force. Similarly, after the excretion is completed, by raising the receiving seat 23, the user can easily stand up.
[0011]
The above-described telescopic tube mechanism 35 is a well-known mechanism body, which drives and expands and contracts the telescopic tube 352 in an electric manner. A switch (not shown) for controlling the operation of the telescopic tube mechanism 35 can be installed on the armrest 24 of the chair body 21.
[0012]
The position where the receiving seat 23 is lowered to the lowest point is the position where a person sits on the toilet auxiliary chair. If covered with the seat 25, it can be used as a general chair. The stock of the receiving seat 23 has a peripheral wall 231 corresponding to the shape of the perforation 211 of the chair body 21, and the outer wall surface of the peripheral wall 231 is fitted to the inner edge of the perforation 211. In the process of raising and lowering the receiving seat 23, all the peripheral walls 231 are held in the perforations 211, so that the safety in use is high.
[0013]
In order to prevent the toilet bowl 22 from colliding with the drive mechanism 30 in any state, the drive mechanism 30 includes an upper frame 32 and a lower frame 31 having a hollow center, and U-shaped rods 33 and 34. The telescopic tube mechanism 35 is installed so as to avoid the toilet 22.
[0014]
[Effect of the invention]
The well-known chair-type toilet 10 shown in FIG. 1 does not consider the maintenance of the user's body surface and dignity when not in use, and requires the assistance of another person when excreting. May hurt. Such a situation tastes unbearable for the user. The chair-type simple toilet provided by the present invention becomes furniture when not in use, and the user can complete the toilet independently, thereby reducing the burden on the caregiver. Therefore, the present invention is a new design that can protect the dignity of the user.
