Description

The present invention relates to a support device installed around a Western-style toilet bowl to assist defecation.

Toilet handrails used for Western-style toilets installed around Western-style toilets are, for example, a pair of left and right right handrail frames and left handrail frames (side frames), and a connecting frame (front frame) that spans them. Install around. A pair of left and right handrail frames are provided on the right side frame and the left side frame (Patent Document 1, [Claim 1]). In order to fix the position of the handrail frame to the Western style toilet, a restraining member (Patent Document 1: fixing member) is pressed against the Western style toilet to fix the position, or the restraining member is connected to the floor or wall surface of the toilet. To fix the position.

Such a toilet handrail device is equipped with a long armrest to facilitate the sitting and standing up of the toilet seat as well as to maintain the comfortable posture of the toilet user during stool, and to invade and evacuate the Western-style toilet bowl. Patent Document 2 shows that even the safe movement of the toilet can be covered by a single toilet device.

Most of these handrail devices are for ensuring the safety of the user, but there are some devices that encourage the user to defecate. For example, in Patent Document 3 ([0002], [0003]), a handrail device devised so that a user with constipation or hemorrhoids does not press the buttocks during defecation and exerts force on the abdominal muscles of the human body. Has been proposed.

As described above, the defecation support device used for the conventional Western-style toilet mainly has a function of arranging the handrail that the user holds when standing and sitting on the toilet seat around the Western-style toilet, and there is not much other function. .. Here, there are statistics that about one-third of middle-aged and older women suffer from constipation, and as the baby boomer generation ages, the demand for relieving constipation will increase. It is considered preferable if the function of assisting defecation is added to the defecation support device to be used. Therefore, we examined the possibility of adding a function to actively assist defecation to users of Western-style toilet bowls.

As a result of the examination, we developed a knee guard located on both sides in front of the toilet seat of a Western-style toilet bowl, a main body frame to which the knee guard is attached, and a fixing member that movably supports the main body frame. Occasionally, it is composed of a pair of left and right knee lateral pads that regulate the opening of both knees by guiding them to be located in the center of the toilet seat with both knees closed and supporting the lateral movement of the knees to regulate outward movement. For the frame, a knee guard is assembled near the tip, the base is attached and fixed to the fixing member, the knee guard is movably connected with a constant movement, and the fixing member is attached and fixed near the periphery of the toilet seat to fix the main body. By moving the frame, it is located in a shelter away from the knees when not in use, and it is moved to a set position that regulates the opening of both knees when in use. It is a support device.

In the device of the present invention, the knee guards are positioned on both sides in front of the toilet seat during use, and when seated, the buttocks are further submerged in the central recess of the toilet seat in a posture of narrowing the distance between the knees. .. The fixing member connected to the base of the main body frame may be fixed in the vicinity of the toilet bowl. For example, a toilet handrail composed of a left and right frame and a connecting frame for sandwiching a Western-style toilet bowl, a wall or a floor of the toilet, and a coupling structure having sufficient strength and rigidity for the Western-style toilet bowl may be used.

It is preferable that the knee guard is movable between a use position in which both knees of the user are held in a narrowed state in the center of the left and right and a retracted position that does not interfere with standing and sitting. As a specific knee guard, the configuration of a pair of left and right knee lateral pads that are addressed from the outside to each of the left and right knees of the user can be exemplified. In this case, the left and right handrail frames and the fixing members fixed in position on the wall surface, and the pair of left and right main body frames pin-connected to the left and right handrail frames and the knee guard rotate or move in parallel with a constant movement up and down or left and right to move the knee guard. Move between the used position and the retracted position.

In addition to the lateral knee pad, the back of the knee is supported at the left and right positions on the front upper part of the toilet seat so that the back of the knee is raised above the knee to regulate the lowering of the knee and set to the knee height set at the time of use. Is provided on the knee guard to support the sinking of the buttocks into the toilet seat, further compressing the lower abdomen and increasing the effect of promoting defecation.

The main body frame that supports the knee guard has a constant movement between the front position where both knees are held narrowed to the center of the left and right by the knee guard and the side position that does not interfere with the standing user. It should be movable.

The main body frame, which is movably connected to the handrail frame or the fixing member attached to the wall surface, rotates or translates up and down or left and right, and becomes movable between the front use position and the side retract position. .. The anterior position is a position in which the user leaning forward supports his / her body by placing his / her hand or forearm elbow on the handrail. The lateral position is the evacuation position on the left or right side of the Western-style toilet bowl or both, which does not interfere with the user standing and sitting. Here, if a rotation stopper such as a meshing of unevenness is provided at least in the use position among the use position and the retracted position, the rotational movement during use can be prevented.

Further, the main body frame that supports the knee guard may be provided with a footrest on which the user sitting on the toilet seat rests his / her feet. The posture of raising the legs and knees to press the abdomen is also effective with the previous knee back pad, but in addition to this, by lifting the legs with the footrest, a further defecation support effect can be obtained as with the knee back pad. ..

A rotating member of the armrest is attached to the main body frame that supports the knee guard, and the knee pad and the armrest are integrally rotated and moved. Whether it is a floor-standing (stationary) type, a type that is bolted to the floor or wall, or a portable toilet, any toilet handrail that has an armrest that allows the user to place his or her hands or elbows to support a forward leaning posture. A guard may be attached.

The footrest has a fixed position where you can rest your foot only in a specific position or freely within a certain width range, and it does not interfere with users who do not need a footrest or when they sit on the toilet seat. There is one that makes it movable between the use position and the retracted position. However, the footrest that can be moved between the use position and the retracted position in the present invention has a pair of left and right configurations supported by a pair of left and right body frames extending from the main body frame, and the main body frame rotates or moves vertically or horizontally. Then, it is preferable to move it between the use position and the retracted position together with the knee guard or independently.

The defecation support device used in the Western-style toilet bowl of the present invention holds both knees in a narrowed state by a knee guard so that the buttocks of the user seated on the toilet seat are sufficiently submerged in the depression and hole in the center of the toilet seat. Make it selfish and facilitate bowel movements. In addition, narrowing both knees with a knee guard and subducting the buttocks into the toilet seat are accompanied by compression or irritation of the lower abdomen, and have the effect of promoting the urge to defecate. In addition to the subduction of the buttocks, the effect of promoting the desire to defecate is further enhanced when the user leans forward. In this case, if the armrest that is movable between the front position and the side position is set to the front position, the user can be stably bent forward with his / her hand or elbow attached.

The back of the knee pad and footrest support the user's knee, which is held with both knees narrowed by the lateral knee pad, and stabilize the posture of the buttock subduction and the compression stimulation of the lower abdomen to facilitate defecation. effective. In addition, the knee guard is restricted from rotating by a stopper at the position of use and can be used safely, and is moved to an evacuation position where it does not get in the way when not in use.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. The defecation support device for a Western-style toilet bowl of the present invention first includes a right handrail frame 11 and a left handrail frame that sandwich the Western-style toilet bowl 4, as seen in FIGS. Pin 12 to the left and right connecting columns 131 and 132 of the handrail frame 1, which is a fixing member connected by the connecting frame 13, to the base of the main body frame that supports the knee guard 2 including the pair of left and right right knee guards 2a and the left knee guard 2b. It is configured by connecting and, if necessary, providing a pair of left and right right footrests 3a and a footrest 3 including a left footrest 3b. In the handrail frame 1, the right handrail frame 11 and the left handrail frame 12 are fixed to the floor surface, and although not shown, the Western-style toilet bowl 4 is sandwiched between the right handrail frame 11 and the left handrail frame 12, and the right handrail frame 11 and The position is fixed by pressing the left handrail frame 12 against the wall surface.

The connecting frame 13 is provided with right connecting columns 131 and left connecting columns 132 made of metal pipes standing at both ends of the connecting beam 133, which is a metal pipe having a substantially V-shape in a plan view. The connecting beam 133 is directed to the front of the Western-style toilet bowl 4 to secure the strength and rigidity of the entire handrail frame 1 and position the handrail frame 1 with respect to the Western-style toilet bowl 4. In the right connecting column 131 and the left connecting column 132, the lower portion to which the right handrail frame 11 and the left handrail frame 12 are fixed and the upper portion connected to the connecting beam 133 of the connecting frame 13 can be separated from each other. , The connecting frame 3, the right handrail frame 11 and the left handrail frame 12 are connected or separated into three parts.

The handrail frame 1 has a pair of left and right right handrails 14 and a left handrail 15 with respect to the right connecting column 131 and the left connecting column 132 of the connecting frame 13. The right handrail 14 of this example makes a horizontal turn between a lateral position that turns right and aligns the direction in the front-rear direction and a front position that turns left and aligns the direction in the left-right direction in front of the Western-style toilet bowl 4. Here, since the right armrest 141 of the right handrail 14 of this example is shifted to the right from the turning center by the right turning portion 142, when the right armrest 141 is horizontally turned to the front position, it and the fuselage of the user. There is room between the armrests. The left handrail 15 has a symmetrical configuration with the right handrail 14, and has a left armrest 151 and a left turning portion 152.

The knee guard 2 of the present invention is attached to such a handrail frame 1. 2 and 3 show the mounting structure of the knee guard 2 and how to use the knee guard 2 by extracting from FIG. In these figures, the footrest 3 described later is also seen. The knee guard 2 restrains both knees of the user U sitting on the toilet seat 41 of the Western-style toilet bowl from the left and right, and includes a right knee guard 2a and a left knee guard 2b. Both shapes are symmetrical. The right knee guard 2a is integrally formed with the right body frame 21a in which a metal pipe is bent and the right body frame 21a assembled near the tip of the right body frame 21a. The bearing pipe 23a is formed of a pipe 23a, and the bearing pipe 23a is rotatably fitted onto the right connecting column 131 of the right handrail frame 11 which serves as a fixing member 16 and is horizontally swiveled. In the case of FIG. 1, the relationship between the shaft and the bearing is an example opposite to that in FIGS. 1 and 2 in which the bearing is interpolated into the shaft.

The right knee lateral pad 22a moves to a retracted position that does not interfere with the user's standing and sitting by turning the right body frame 21a to the right, and turns to the left of the right body frame 21a to the user's right leg (near the knee). The user's knees are brought into contact with each other, moved to a position where the user's knees are held in a narrowed state in the center of the left and right, and locked with the locking groove 171 of the locking mechanism 17 and the pin 172. The movement is constant by the pin connection between the right bearing pipe 23a and the right connecting column 131. Here, since the left knee guard 2b is symmetrical, the explanation of the movement of the left knee guard 2b is omitted, but it is composed of the left main body frame 21b, the left knee lateral pad 22b, and the left bearing pipe 23b.

In addition to the knee guard 2, the defecation support device used in the Western-style toilet bowl of this example includes a footrest consisting of a right footrest 3a and a left footrest 3b on a handrail frame (12, 11) as shown in FIGS. 1, 2, and 3. 3 is integrally or separately connected to the main body frame 21a of the knee guard, and is provided as a pair on the left and right, and can be turned horizontally. Here, the footrest 3 also has a fixed structure in which the left and right sides are integrated or the mounting location is selected. For example, as shown in FIGS. 2 and 3, the footrest arms 32a and 32b are attached to the connecting columns 131 and 132 by separate bearing pipes 33a and 33b corresponding to the left and right feet of the user.

In addition to the knee guard 2, the back of the knee is supported at the left and right positions of the front upper part of the toilet seat 41 in a state of rising above the knee to regulate the lowering of the knee, and the back of the knee is set to the height of the knee set at the time of use. When the pad 24 is provided on the knee guard 2, a more optimal defecation posture can be obtained, and the defecation promoting effect is further enhanced. An example thereof is shown in FIGS. 4 to 8.

As is clear from these usage state explanatory views, those in FIGS. 4 and 5 have a structure in which the left and right knee back pads are integrally formed and the left and right knee pads are integrally rotated up and down. 6 to 8 have a structure in which the left and right knee lateral pads 22 and the knee back pads 24 are formed separately, and the left and right sides rotate horizontally, and the movement is restricted by the engagement of the locking mechanism or the like. A slide structure is also possible instead of such a rotating structure.

Further, FIG. 6 is a side view showing a state in which the knee guard 2 and armrests 141, 151 of the present invention are attached to the connecting columns 131, 132 of the left and right handrails 14, 15 of the handrail frame 1, FIG. 7 is a front view thereof, and FIG. 8 is a front view thereof. It is the plan view. Armrests 141 and 151 are provided on the right handrail 14 and the left handrail 15. Knee guards 2a and 2b are provided under these handrails by forming the knee lateral pads 22a and 22b and the knee back pads 24a and 24b in an angle shape, respectively. The entire knee guard and armrest are supported by the left and right right connecting columns 131, the left connecting column 132, and the connecting beam 133.

FIG. 9 is a plan view showing a structure in which the knee guard of the present invention is attached to the wall surface of the toilet. Here, the fixing members 16 pin-coupled to the base portions of the main body frames 21a and 21b are attached to the left and right wall surfaces 5, and the tip is attached. Lateral knee pads 22a and 22b and back knee pads 24a and 24b as knee guards 2 are rotatably attached to the portion. Further, FIG. 10 is a plan view showing a structure in which a knee guard similar to that in FIG. 9 is attached to the handrail frame 1 of the portable toilet.

The defecation support device used for the Western-style toilet bowl of the present invention is used according to the following procedure. As seen in FIGS. 2 and 3 showing the usage state of the knee guard (and footrest) of this example, the user U has the right knee guard 2a (and the right footrest 3a) and the left knee guard 2b (and the left footrest 3b). ) Is moved to an unobtrusive lateral evacuation position as shown in FIGS. 9 and 10, and sits on the toilet seat 41 of the Western-style toilet bowl 4.
Since the right knee guard 2a, the left knee guard 2b, the right footrest 3a, and the left footrest 3b are all moved to both sides avoiding the front part of the Western-style toilet bowl 4, they do not interfere with the standing and sitting of the user.

After sitting on the toilet seat 41 in the posture shown in FIG. 2, the user U moves the right knee guard 2a and the left knee guard 2b to the positions of use, respectively, and moves the right knee lateral pad 22a as shown in FIG. The left knee lateral pad 23a is brought into contact with the knee of the right leg from the right, and the left knee lateral pad 23a is brought into contact with the knee of the left leg from the left. The right knee guard 2a and the left knee guard 2b at the use position are closely spaced so that both knees of the user are narrowed to the center of the left and right. Further, since the right footrest 3a and the left footrest 3b are also moved to the use positions in conjunction with the right knee guard 2a and the left knee guard 2b, the user shifts his / her foot and puts them on the right footrest 3a and the left footrest 3b.

Rotational movement is regulated by a locking mechanism 17 such as meshing of irregularities between the pin coupling shaft of the right handrail frame 11 and the left handrail frame 12 and the fixing member 16 and the bearing, and the product can be used safely at the set position. As a result, both knees of the user sandwiched between the right knee lateral pad 22a and the left knee lateral pad 22b of the right knee guard 2a and the left knee guard 2b are held in a narrowed state in the center of the left and right. Further, when the back pad of the knee is added to the lateral pad of the knee guard 2, the defecation posture is further stabilized and the anus is easily opened. Figures 4 to 10 are examples.

In addition, the user puts his / her foot on the right footrest 3a and the left footrest 3b that have moved to the use position in conjunction with the right knee guard 2a and the left knee guard 2b, so that the knee is relatively higher than the buttocks. Since the posture is leaning forward so that the arm touches the kneecap, the sinking of the buttocks into the toilet seat is further assisted, and the lower abdomen is compressed and stimulated.

As shown in FIGS. 2 and 3, the user moves the right handrail 14 and the left handrail to the front position after the narrowed state of both knees is maintained, and bends forward with the hand or elbow. Since the user puts his / her hand or elbow on the right handrail 14 and the left handrail 15, this posture is maintained in a stable manner. As a result, the buttocks are further submerged, and the lower abdomen of the user who leans forward is pressed against the place where both knees are aligned, and the lower abdomen is compressed or stimulated to promote the urge to defecate. In this way, it is easy to defecate, and by giving a desire to defecate, it is possible to defecate without difficulty.

The user who has completed defecation moves the knee guard 2 to the left and right lateral positions, and with the foot removed from the footrest 3, moves the defecation support device of the present invention to the evacuation position on both handrail sides or the wall surface side. (See FIG. 9 or FIG. 10). The main body frame 21 of the knee guard 2 is rotated to the set retracted position and stands by. In order to safely fix the retracted position, a locking mechanism 17 may be provided if necessary.
