[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a nursing tub that allows an elderly or disabled person to input.
[0002]
[Prior art]
A conventional nursing bathtub is provided with an elevating suspension floor at the top of the bathtub body, for example, as disclosed in Japanese Patent Application Laid-Open No. 2001-269384, and lays a bather on the suspended suspension floor, and then lowers the suspension floor into the bathtub body. The bath was immersed in hot water for bathing, and then the suspended floor was lifted from the bathtub body to take a bath.
[0003]
Alternatively, for example, as in the invention described in Japanese Patent Application Laid-Open No. 2000-271184, the sliding chair is stored in the bathtub body with the assistance chair, and the bathnut body is tilted with water pressure or the handle is turned to rotate the sliding nut, and The shaving shaft was moved, the steel wire was pulled, the bathtub body was tilted, water was put into the bathtub, and input was performed.
[0004]
[Problems to be solved by the invention]
However, the former method requires a mechanism for raising and lowering the suspended floor as well as providing the suspended floor, and the structure is complicated.
[0005]
In addition, since the unstable suspended floor is raised and lowered, it is inevitable to give the bather an uneasy feeling, and it is difficult to adjust the lifting speed and the like.
[0006]
Furthermore, even in the latter method, a water pressure pump is required to tilt the bathtub body, and the structure is complicated. In addition, when the handle is manually tilted, the bathtub cannot be tilted if the handle is required to be rotated considerably, the structure is complicated, and much labor is required until the handle is tilted.
[0007]
Furthermore, since the bathtub is configured to be pulled by a wire, if the bathtub is used for a bath that constantly handles water, there is a possibility that the wire may be deteriorated or cut due to rust or the like.
[0008]
In addition, because the mechanism for tilting the bathtub is complicated, it is difficult to fine-tune, interrupt, and resume the operation speed, and the movement is rapid, changes in speed, or does not move easily, I was giving anxiety.
[0009]
[Means for Solving the Problems]
The present invention has been made for the purpose of solving the above-described problems, and even in a state where the bather is stored, the bathtub can be moved according to one's own intention with a slight force while checking the state of the bather. It is an object of the present invention to provide a nursing bathtub that can freely enter a bathing state. For example, the following configuration is provided as a means for achieving the above object.
[0010]
That is, care provided with a bathtub body, a base having a locking portion for swingably locking the bathtub body near the center of the bottom of the bathtub body and a positioning portion capable of restricting the positioning of the bathtub body in a bathing position. A bathtub having a balance mechanism that balances the weight of the bathtub body back and forth with the locking portion as a fulcrum in a state in which a bather is stored in the bathtub body, and swings the bathtub body with a slight force. The locking portion of the base is provided with a bathtub supporting member provided with a bearing hole for pivotally supporting the bottom of the bathtub body in the vicinity of the distal end thereof, and the supporting member is erected near both sides of the bottom of the bathtub body. The positioning portion of the base portion is characterized in that a top portion stands up from a head position of the bathtub body to a locking position in a bathing state position when the bathtub body swings.
[0011]
And, for example, the balance mechanism portion includes at least two spring members, and locks one end of the spring member at a front and rear bottom portion separated from the locking portion of the bottom of the bathtub main body, and each of the other spring members The end portions are collectively locked at the collective position of the base portion.
[0012]
Further, for example, the combined position of the balance mechanism is movable according to the weight of a bather. Alternatively, a weight scale for measuring the weight of the bather is provided at the foot position of the bathtub body when the bather is stored, and the grouping position can be adjusted according to the weight of the bather.

Further, for example, a lock mechanism that can be fixed to the positioning portion is provided at a head end of the bathtub body.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention according to the present invention will be described in detail with reference to the accompanying drawings.
[0016]
The nursing bathtub of the present embodiment is provided with a balance mechanism portion that swings around the center of the bathtub as a swinging fulcrum, and maintains a balance in front and rear even when a bather enters the bathtub, For example, the bathtub can be easily and smoothly swung even with one hand.
[0017]
That is, the bathtub of the present embodiment has a weight balance in front and back with the bather in the bathing posture, with the fulcrum near the center of the bottom of the bathtub as in "Yajirobei", and also uses power, water pressure, and electric power. The caregiver who easily cares for can swing the bathtub to the bathing position by applying a slight force to the front or the rear, or swing the bathtub to the inclined state after bathing.
[0018]
1 is a perspective view of a nursing tub according to an embodiment of the present invention, FIG. 2 is a front perspective view of a nursing tub of the embodiment, and FIG. 3 is a top view of a bathtub body of the embodiment. is there.
[0019]
Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS.
[0020]
In the figure, reference numeral 100 denotes a base (leg) for swingably locking the bathtub main body 200, 200 denotes a bathtub main body, and 310 and 320 denote oil springs for balancing the weight of the bathtub main body 200. The spring is not limited to an oil spring, and may be a gas spring or a spring formed of an elastic member such as a spring member. The durability is improved by configuring the spring in a liquid-tight manner.
[0021]
One end of the oil springs 310 and 320 is locked at the bottom position of the upper body storage portion 204 and the bottom position of the leg storage portion 203 at the one end, and the other ends are collectively connected to a spring locking plate 335 described later. Locked.
[0022]
A sliding bar 330 is slidably locked back and forth on the base 100 to which a spring locking plate 335 for locking the oil springs 310 and 320 together is fixed near the center.
[0023]
Reference numeral 350 denotes an adjustment handle, and reference numeral 351 denotes an adjustment shaft connected to the adjustment handle 350. The cylinder shaft 365 screwed to the adjustment shaft 351 by rotating the adjustment shaft 351 resists the spring force of the spring 360. It moves in the direction of the arrow in FIG. 2 to slide the slide bar 330 fixed to the end of the cylinder shaft 365.
[0024]
When the sliding bar 330 slides, the position of the spring locking plate 335 moves, the combined position of the oil springs 310 and 320 changes, and the stress of the oil springs 310 and 320 can be changed. In the present embodiment, the positioning position of the spring locking plate 335 corresponding to the bather's weight is represented by a weight display on the cylinder shaft 365 as shown in FIG. 2, and the cylinder position corresponds to the bather's weight. The handle 350 may be rotated as described above.
[0025]
Reference numeral 400 denotes a water pipe for discharging the bath water in the bathtub, and a drain plug 410 is provided on the way. The opening and closing of the drain plug 410 is performed by operating the lever 411.
[0026]
Reference numeral 500 denotes a safety soft bar which is a holding rod for a bather to hold by hand when in a bathing state. For example, the older a person is, the more the human body leans forward and becomes rounder. Since the bather in such a state has the soft bar 500 that can be held in front of the body, the state of being held by hand becomes a state similar to the state of being in the womb of the mother, so the most resilient posture is reasonable You can get it.
[0027]
Note that a lock pin that can protrude outward by elastic force is provided at a handle position of the soft bar 500, and the lock pin is fitted into a hole provided at the soft bar position of the handle 265. Thereby, the soft bar 500 is locked at the position shown in FIG. 1 or FIG.
[0028]
When removing the soft bar 500, the lock pin is retracted into the bar to release the lock and pull out. When the soft bar is not used, it is desirable to store the soft bar in a cylindrical soft bar storage case 262 provided on the side surface of the bathtub body.
[0029]
Reference numeral 610 denotes a digital weight scale, which automatically measures the weight when the bather gets on the footrest 203 in order to take a bath in conjunction with the footrest 203 of the bathtub body 200, Is digitally displayed on the weight display section 650. For this reason, the caregiver turns the adjustment handle 350 and slides the cylinder shaft 365 with reference to the measured weight of the weight scale 610, and adjusts the memory displaying the position where the balance can be obtained for each weight to the measured weight.
[0030]
Even if the bath scale is not provided, if the weight of the bather is known in advance, if the position of the cylinder shaft 365 is adjusted by turning the spring moving handle 350, the bathtub body can be balanced.
[0031]
The above-described base 100 is assembled mainly by shaping a pipe member. Casters with adjuster feet are provided at four locations on the bottom side of the U-shaped member 110 forming the bottom frame, so that the casters can be easily moved.
Since the floor surface in the bathtub is made almost in consideration of drainage of water, the floor surface is not horizontal, and the bathtub can be kept horizontal by providing this adjuster foot.
In the present embodiment, safety is ensured because reinforced rubber is provided on the installation bottom surface of the adjuster foot to prevent the care tub from slipping on the floor surface.
[0032]
A standing member 120 for positioning and fixing the top 201 of the bathtub main body 200 is fixed to the U-shaped head side of the U-shaped member 110 by welding or the like, and the safety lock mechanism 210 of the bathtub main body 200 is fixed to the top. A receiving mechanism 125 that is locked and can maintain the locked state is provided.
[0033]
Reference numeral 130 denotes a reinforcing member of the U-shaped member 110, which is fixed to the pie members on both side surfaces by, for example, welding. Reference numeral 140 denotes a bathtub supporting member which is erected on the pipes on both sides of the U-shaped member 110 by welding or the like, and a shaft 160 for pivotally supporting the bathtub body 200 in the vicinity of the tip portion. And a bearing portion for carrying out.
[0034]
The fixing position of the bathtub shaft supporting member 140 is a position where the head 201 just comes into contact with the top of the standing member 120 when the bathtub body 200 is in a bathing state.
[0035]
One end of a cylinder shaft 365 that slides in the direction of the arrow in FIG. 2 according to the rotation of the adjustment handle 350 is screwed to the reinforcing member 130 via a spring 351, and the cylinder shaft 365 expands and contracts as the adjustment handle 350 rotates. Then, the slide bar 330 connected to the other end of the cylinder shaft 365 slides, and the position of the spring locking plate 335 fixed to the slide bar 330 changes.
[0036]
When the position of the spring locking plate 335 moves to the right in FIG. 2, the spring force of the oil spring 320 increases, and the spring force of the oil spring 310 decreases.
[0037]
On the other hand, when the sliding bar 330 is moved to the left in FIG. 2, the spring force of the oil spring 310 is increased, and the spring force of the oil spring 320 is reduced.
[0038]
Therefore, if the position of the sliding bar 330 is properly adjusted, the left and right balance force of the bathtub body 200 can be adjusted, and a bearing that supports the shaft 160 like "Yajirobei" regardless of the weight of the bather. With the part 230 as a fulcrum, the weight can be balanced back and forth.
[0039]
As described above, in the present embodiment, the caregiver who easily cares without using any power, water pressure, electric power, or the like swings to the bathing position by applying a slight force to the front or the rear with a hand. The bathtub can be swung in an inclined state if it is moving or after bathing.
[0040]
In the present embodiment, the bathtub main body 200 has a bottom central portion 270 that is shallower than the footrest portion 203 and an upper body portion that is formed to be deeper again, so that the user can just sit in the bathtub when tilted. The inside of the bathtub is shaped like a stool. The middle part of the central part 270 is formed in a cut-out state, for example, so that it is easy to wash a pubic part of a bather, and it is configured to maintain the cleanliness of the bather.
[0041]
The weight scale 610 is attached to the rear side surface of the footrest 203. For this reason, it is configured so that the bather is tilted as shown in FIG. 1 when bathing, and the bather stands on the footrest portion 203 with the bathtub body tilted so that the weight can be measured by the weight scale 610. After that, you can immediately sit down in the bathtub.
[0042]
Thus, the bather can enter the bathtub without taking an unreasonable posture, and can prepare for bathing in a comfortable state. In addition, 261 is a shower hook.
[0043]
Reference numerals 701 and 702 in FIG. 3 denote seat belts provided with a suction cup at the base and a magic zipper near the distal end, and prevent a bather from being in an unstable position such as floating in the bathtub.
[0044]
Since the seat belts 701 and 702 of this embodiment have a structure in which the seat belts are fixed in the bathtub with a suction cup, a product manufactured according to the bather is employed, and a bathtub that is suitable for the bather is selected each time the bather takes a bath. Attached to.
The back of the magic zipper that directly touches the bather's skin on the seat belts 701 and 702 uses the rubber skin used for wet suits, etc., so that it can be soft even when in contact with the bather's body surface. There is no structure.
[0045]
Thus, when not in use, it can be removed and does not hinder cleaning of the bathtub. At the same time, the position where the suction is performed by the suction cup can be freely set, so that the seat belt can be put on the optimum portion according to the body shape of the bather.
[0046]
The footrest portion 203 of the present embodiment has a non-slip function, and is attached to a portion where the bather places his / her feet when entering the bathtub. Similarly, a pillow 205 is attached to the head portion of the bathtub that becomes the head when taking a bath.
[0047]
The footrest 203 and the pillow 205 are attached by being sucked into the bathtub, and can be removed freely by holding and peeling off the end portion. The air can be easily absorbed by discharging the air between the bathtub. For this reason, in the case of cleaning the bathtub, the bathtub can be detached and cleaned separately from the bathtub, so that the bathtub can be kept clean.
The structure of the footrest portion 203 is not limited to the above-described example of the suction, and the footrest portion 203 may be configured by directly performing a no-slip process on a portion of the bathtub where the foot is to be placed. In this case, it is not necessary to peel off each time, and it is possible to prevent deviation. Even in this case, there is little hindrance to cleaning.
[0048]
In the present embodiment, the shaft 160 is mounted between the bearings provided on the bathtub supporting member 140 of the base 100 near the middle of the bottom of the bathtub main body 200, for example, at the bottom of the stool portion as shown in FIG. A bathtub bearing member 230 having a penetrable bearing portion is formed, and a shaft 160 supported between the bearing portions of the bathtub bearing member 140 is passed through the bearing portion of the bathtub bearing member 230. It is configured to be swingable with the shaft 160 as a fulcrum.
By forming the bearing portion to include, for example, a stainless steel bearing, the bathtub body 200 can be swung more smoothly.
[0049]
In addition to being simply swingable, oil springs (or air springs) 310 and 320 are arranged between the front and rear bottoms of the bathtub main body 200 and the spring locking plate 335. With the bather being housed in the bathtub, the weight can be adjusted so that the front and rear weights can be balanced by using the force. The bathtub can be swung at the speed desired by the caregiver without applying any excessive force even when trying to lay it down horizontally.
[0050]
That is, since the conventional one has a structure in which the bathtub is swung by a cylinder or the like using water pressure, it is very difficult to freely adjust the amount of water to be put into the cylinder, and particularly, it is once being tilted once in the horizontal direction. Restoring from the state again requires complicated operations and is extremely difficult.
[0051]
Even with the method of pulling the wire attached to the end of the bathtub, it is difficult to control the swing speed and direction, and during swing control, you must concentrate on controlling the wire and check the condition of the bather. I could hardly rock it.
[0052]
However, according to the present embodiment, the rocking can be performed with a small force, and the control of the rocking direction can be performed by simply applying a force in a direction in which the user wants to tilt, and the rocking control is performed according to the intention of the caregiver. Becomes possible.
Since the handle 265 is provided, not only can the soft bar 500 be fixed, but also when the bathtub is moved, the handle 265 can be moved not only by pushing the standing portion 120 but also by moving the handle.
[0053]
At the time of bathing using the assistance bathtub of the present embodiment having the above-described configuration, first, the bathtub is moved to a place where a bath can be taken, for example, a bathroom, and tilted as shown in FIG. (The installation surface) is in contact with the floor.
[0054]
Seat belts 701 and 702 suitable for the bather used by the bather at the time of bathing are selected from the body type of the bather. Then, the suction cup is attached to an optimal position in the bathtub by suction. In addition, when it is already mounted, it is sufficient to adjust the mounting position only when necessary.
[0055]
To measure the weight of the bather in this state, the weight scale 610 is set to the weight measurement mode, and the bather's feet are placed on the foot rest (weight scale portion) to measure the weight. The weight measurement result is digitally displayed on the digital display unit 650.
[0056]
Then, the bather is stored in the bathtub by the seat belts 701 and 702, and the soft bar 500 is fixed to the handle 265 so that the bather can grasp the bather.
[0057]
At the same time, it is checked whether or not the weight of the bather and the weight display position of the cylinder shaft 365 are adjusted within an allowable range. If re-adjustment is necessary, the adjustment handle 350 is turned to change the weight display position of the cylinder shaft 365. Keep it within the allowable range.
[0058]
Adjusting the position of the cylinder shaft 365 results in a so-called "Yajirobei" state in which the weight of the head side and the foot side is balanced with the bather in the bathtub, so the caregiver applies a slight force. The bathtub can be easily shifted to the bathing state position only by using only the bathtub.
[0059]
Even in this case, the swinging speed can be freely adjusted depending on the degree of application of the force, and the swinging direction can be similarly changed. For this reason, the assistant can swing the bathtub while communicating with the bather, and does not give the bather anxiety.
[0060]
In addition, this balance mechanism can also have a simple structure of two oil springs 310 and 320. In addition, if the optimum balance position is grasped for each bather, the balance can be easily obtained without a scale.
[0061]
When the bathtub main body 200 is tilted horizontally to reach the bathing position, a necessary amount of hot water is poured into the bathtub. At this time, by keeping the drain plug 410 closed, hot water is accumulated in the bathtub and bathers can be bathed.
In the present embodiment, the bathing state of bathtub main body 200 is set so that the bathtub stands about 5 degrees from the horizontal state. This ensures that even if hot water overflows during bathing, which will be described later, the water overflows from the end in the toe direction, so that the bather can be safely drained without giving fear or the like. In order to
For this reason, even if the drain plug 410 is clogged or the drain lip 410 of the drain plug 410 is operated improperly and drainage cannot be performed properly, the drain can be drained from the foot, and the water can be discharged to the head. This prevents the bather's head from sinking into the hot water and drowning. In addition, this bathing position is not limited to only the inclination of about 5 degrees, and can be appropriately selected. Alternatively, the inclination may be changed depending on the part to be washed during bathing.
While taking a bath, wash the bather's body and keep the hot water flowing at a certain rate. Rinse with hot water while washing detergent or washing the head.
For this reason, during bathing, the lever 411 of the drain plug 410 is operated to control a state in which a certain amount of hot water flows out, and control is performed so as to balance the hot water supply amount and the drainage amount.
In addition, even if the amount of hot water supply is temporarily increased, since the foot side of the bathtub body 200 is slightly lowered as described above, the hot water flows out from the foot direction, so that the bather is given a fear. There is nothing.
[0062]
When bathing is completed, the drain plug 410 is opened wider by operating the lever 411 of the drain plug 410 to discharge the hot water in the bathtub, and the bathtub is tilted again with the head 201 etc. and the bather is seated. To
Then, the soft bar 500 is removed, the seat belts 701 and 702 are removed while being stored in the storage portion 262 and the body is wiped while being placed on the footrest portion 203 and moved out of the bathtub to complete bathing.
[0063]
In the seated state, a safety lock mechanism (not shown), for example, a mechanism for restricting displacement in the horizontal direction and maintaining the seated position of the bathtub is provided. The mechanism may be configured to be released. This can prevent the bathtub from moving carelessly.
[0064]
Further, even when the sliding cylinder 365 is not provided and the oil springs are collectively fixed at one place, the weight balance can be maintained to some extent. For this reason, the bathtub can be swung, although some force is required as compared to a state where the balance is completely balanced. For this reason, when manufacturing at low cost, the bathtub can be easily swung manually without a complicated mechanism, even if the structure does not include a balance adjustment mechanism that changes the weight balance according to the weight. .
[0065]
As described above, the human body has a higher upper body than the lower body, so that when a bather enters the bather, the excess load is applied in a certain direction, for example, by installing an oil spring (for example, a hydraulic gas spring). The bathtub in which the bathtub is placed is always balanced between left and right like "Yajirobei", so it can be easily rocked with a little force.
[0066]
In particular, in order to achieve a weight balance with a small error, the oil reaction force (gas reaction force in a gas spring) is determined with respect to the overload of the oil pulling, so the balance changes when the weight of the bather changes significantly. It is equipped with a configuration to improve the point, the contact point of the oil spring is moved and set according to the weight of each person, and if necessary, attach a weight measuring device to the part on the back side of the bottom of the bathtub before bathing Because the weight of the bather can be measured, and by adjusting the position of the oil spring to receive the weight with reference to the weight of the bather, the contact point of the oil spring was changed and the load resistance at a constant speed was reduced. An assisting bathtub can be provided in which the assisting person can smoothly move and operate the bathtub with a small force.
[0067]
Further, in this case, if a stronger force is applied, the swinging speed of the bathtub can be increased in proportion thereto, so that the assistance bathtub can be operated according to a detailed caregiver's intention.
[0068]
This eliminates the need for a complicated structure such as a hydraulic cylinder, electric motor, or wire that pulls and swings the bathtub, making it robust, easy to use, excellent in safety, and one person bathing in hygiene. Every time you do, you can drain the hot water from the bathtub and make it an easy and complete cleaning bathtub.
[0069]
In the present embodiment, since the inside of the bathtub is formed in a seat shape and the central portion is made shallow, not only is it easy for bathers to enter, but also the amount of hot water required can be reduced. For example, when a person weighs 60 kg enters the bathtub, the bathtub can be filled with about 80 liters of hot water for about eight minutes, and the amount of hot water can be saved without difficulty.
[0070]
As described above, according to the present embodiment, the balance of weight before and after the center of the bathtub is set as the fulcrum according to the bather, so that even a bather of any weight can apply a slight force. The bathtub can be moved and operated more smoothly. If the force is further applied, the swing speed of the bathtub body 200 can be correspondingly increased, and the swing direction can be easily reversed.
Furthermore, according to the embodiment, even if the bather in the bath event during bathing has become a situation requiring emergency such ill, even more by removing the locking mechanism 125 of the tub If the force is applied to raise the bathtub body 200, the more the force is applied, the higher the speed of the swing, and the more quickly the bather can be protected from the bathing state in the bathtub.
At this time, even if hot water is stored in the bathtub, it can be quickly drained from the feet, no bather jumps out of the bathtub, and it does not fall into the bathtub, and quick response is safe. Can be done.
[0071]
