Description

  TECHNICAL FIELD The present invention relates to a clamp mechanism for a bathing aid that assists in getting in and out of a bathtub.

  It is well known that a bathing aid equipped with a swivel chair or handrail is attached to the side wall of a bathtub to assist an elderly person or a person with weak legs to enter or leave the bathtub when entering the bathtub. . For example, Patent Literature 1 discloses an invention of a bathing assisting tool in which a handrail is attached to an upper part of a clamp mechanism capable of holding a side wall of a bathtub. Further, Patent Literature 2 discloses an invention of a bathing assisting device (rotating chair for bathtub) in which a seat plate is rotatably provided above a clamp mechanism capable of holding a side wall of a bathtub, and a backrest is provided on the seat plate. Is described.

  As shown in FIG. 13, a clamp mechanism 80 of a bathing aid provided with a handrail shown in Patent Document 1 has a cylindrical shape that supports a movable plate (holding member) 81 that is in contact with an inner surface of a bathtub side wall. A nut 83 is attached to the movable frame 82, and a screw member 84 screwed to the nut 83 is rotated by operating a knob 85, so that a fixing plate (a holding member) 86 that comes into contact with the inner surface and the upper surface of the bathtub side wall. , And the bathing aid can be fixed to the side wall of the bathtub. Reference numeral 87 denotes a handrail. Further, in the clamp mechanism of the bathing assisting tool (rotating chair for bathtub) to which a rotatable seat plate is attached, a screw member having a pressing plate (a holding member) attached to an end. , The pressing plate is moved to the side of the side plate of the support plate to be in a tightened state, and the bathing aid can be fixed to the side wall of the bathtub (see FIG. 1 of Patent Document 2).

  When the bathing aid is attached, it does not interfere with a bather who does not need to enter and exit the bathtub, and since the bathtub cannot be covered, the bathing aids described in Patent Documents 1 and 2 can be used. Like an aid, it is usually removable.

When attaching the bathing aid to the bathtub side wall, the interval between the holding members that will come into contact with the inner surface and the outer surface of the bathtub side wall is determined in advance by the thickness width of the bathtub side wall so as not to damage the bathtub side wall at the time of installation. Must be large enough to allow for room.
Usually, a liner having a function of preventing slippage by increasing friction with the surface of the bathtub is bonded to the surface of the holding member, in addition to a cushion function of not scratching the surface of the bathtub. For this reason, if there is not enough space between the holding members, one or both of the holding members stick to the surface of the bathtub during the attaching or detaching work of the bathing assisting tool, and the holding member is placed at a predetermined position on the side wall of the bathtub. It often occurred that the bathing aid could not be located or that the bathing aid could not be easily lifted from the bathtub side wall.

For this reason, the interval between the holding members that come into contact with the inner surface and the outer surface of the bathtub side wall of the clamp mechanism of the bathing auxiliary device before or after the bathing auxiliary device is attached is usually determined in advance by the thickness width of the bathtub side wall. About 1.5 to 3 times as large as.
For this reason, in the installation of the conventional bathing assisting device, it is necessary to turn the knob of the screw member several tens of times to narrow the interval between the holding members and to perform the tightening. Similarly, when removing, it is necessary to reversely rotate the knob of the screw member several tens of times to widen the interval between the holding plates after releasing the tightening. Time and effort was a burden.

Reference numeral 2 denotes a moving-side frame to which a holding member 21 that is in contact with the inner surface of the side wall of the bathtub 200 is attached.

As can be seen from FIGS. 1 and 2, the clamping mechanism of the present embodiment includes two main body frames 1 and two moving-side frames 2, and a single holding member 11 common to the two main body frames. The two moving-side frames 2 support one holding member 21.
When the rotating seat plate of the swivel chair is installed on the clamp mechanism, it is more stable to install the rotating seat plate on two main body frames than on one main body frame. It is already shown in Patent Literature 2 that even with one main body frame, a rotating seat plate can be placed by using a wide main frame (see FIG. 2 of Patent Literature 2). ).

  When a swivel chair is attached as a bathing aid on two body frames, the seat of the swivel chair is attached via a base (both not shown) (see FIG. 12). As can be seen from FIGS. 1 and 2, the base is formed on the roof 1a of the main body frame 1, but is fixed to a hole (no drawing number) by a screw or the like. In this embodiment, two holes are formed in each body frame 1, and screws are fixed at four holes in total. Note that a bearing can be inserted between the base and the seat plate so that the chair can rotate freely. Such a rotation mechanism is a known technique. It is also well known that the rotation mechanism is provided with a rotation lock unit and a rotation range restriction unit.

  As can be seen particularly from FIG. 5, the main body frame 1 has a substantially U-shaped cross section (the open side of the substantially U-shaped surface faces downward) and a substantially な る (gamma) -shaped cross section integrally connected to the portion. And a roof part 1a is formed on the upper part. A hanging portion 1b made of two triangular plate members is integrally formed on two sides of the portion having a substantially U-shaped cross section.

In addition, two sides of the section having a substantially Г (gamma) -shaped cross section have a height (vertical length) shorter than that of the other, forming a substantially 部 cross section together with the roof 1a. are doing. By doing so, the guide 4, the lever 5, and the spring 6 provided on the moving side frame 2 can move along the main body frame 1 as described later.
In FIGS. 1 and 2, the longer side of the two sides of the substantially フ レ ー ム (gamma) -shaped portions of the two main body frames 1 is inward (the two sides). (Between the body frame 1).

  As can be seen from FIG. 5, one end of the main body frame 1 (the end having a section having a substantially U-shaped portion) is closed by a plate-like body having a hole (no drawing number). The screw shaft portion 31 of the screw member 3 having a knob (knob) on the head, which will be described later, is inserted into the hole.

A holding member 11 is attached and fixed to the main body frame 1. As can be seen from FIGS. 1 to 3, the holding member 11 is made of a frame material having a substantially inverted L-shaped cross section, and of the two portions forming the substantially inverted L shape, the vertical portion 11 a is the outer surface of the bathtub side wall. , And the horizontal portion 11b extending like an eave from the upper end of the vertical portion 11a comes into contact with the upper surface of the bathtub side wall.
A liner 11c such as a rubber sheet or a soft plastic sheet is usually attached to a surface of the holding member 11 which comes into contact with the outer surface and the upper surface of the side wall of the bathtub in order to prevent slippage and protect the bathtub (FIG. 3).

  As can be seen from FIG. 5, the hanging portion 1b of the main body frame 1 has a side extending vertically downward and a side extending downward in an inclined direction. The lower edge of the longer side of the two sides extending vertically downward and the two sides of the substantially 辺 (gamma) -shaped section is narrowed. The holding member 11 is attached to the main body frame 1 by bringing the back surface of the holding member 11 into contact and fixing it by welding or the like (see FIG. 2).

  As described above, the screw shaft portion 31 of the screw member 3 is inserted into the hole formed in the plate-like body closing one end of the main body frame 1 (see FIGS. 3 and 5). The roof portion 1a of the main body frame 1 has a length sufficient to cover the entire screw shaft portion 31 of the screw member 3. As will be described later, a knob 32 is formed on the head of the screw member 3.

  The moving-side frame 2 is made of an inverted L-shaped frame member, as shown in FIGS. 1 and 3, and has a vertical portion 2a and a horizontal portion 2b. As can be seen from FIG. The cross-section is substantially U-shaped except for the end on the knob 32 side of the vertical portion 2a (the substantially U-shaped open side of the vertical portion 2a is on the inner side of the bathtub side wall, and the substantially U-shaped open side of the horizontal portion 2b is the upper side of the bathtub side wall. , Respectively). 9 does not show the main body frame 1 (see FIG. 3).

  As shown in FIG. 9, one end of the left and right sides forming a substantially U-shaped cross section is missing at the end of the screw member 3 of the horizontal portion 2 b of the moving side frame 2 on the knob 32 side. A guide 4 to be described later is attached and fixed to the remaining side portion or the back portion of the substantially U-shaped cross section (a portion corresponding to the ceiling of the horizontal portion 2b). The guide 4 is arranged so that a part of the guide 4 protrudes from a surface of a portion corresponding to the missing side portion.

  The horizontal portion 2b of the moving side frame 2 is placed on the horizontal portion 11b of the holding member 11 supported by the main body frame 1, and the roof portion 1a of the main frame 1 has a substantially Г (gamma) -shaped cross section. , So that the upper surface of the horizontal portion 11b of the holding member 11 can be moved (slid). In FIG. 3, when the horizontal portion 2b of the moving frame 2 moves from left to right on the horizontal portion 11b of the holding member 11, the vertical portion 2a of the moving frame 2 is attached to the left end of the horizontal portion 11b. Can move until they touch.

  It is desirable to attach a holding member 21 via a swing member 22 to the vertical portion 2a of the moving side frame 2. It is also possible to directly attach the holding member 21 to the vertical portion 2a of the moving frame 2 without welding via the swing member 22 by welding or the like.

The holding member 21 is formed of a plate-like body, and is a member that comes into contact with the inner surface of the bathtub side wall. As can be seen from FIG. 3, the upper end of the holding member 21 is formed of the holding member 11 of the main body frame 1. It must be located below the height of the horizontal part 11b.
Similar to the holding member 11, a liner 21a such as a rubber sheet or a soft plastic sheet is usually attached to the surface of the holding member 21 that comes into contact with the bathtub, similarly to the holding member 11, in order to prevent slippage and protect the bathtub (FIG. 3).

  The swing member 22 has a substantially U-shaped cross section (see FIGS. 1 and 10), and the holding member 21 is attached and fixed to the outer surface of a portion corresponding to the back of the substantially U-shape. The vertical portion 2a of the moving side frame 2 is inserted into a portion corresponding to the concave portion. Here, the two side portions of the swing member 22 are semicircular, but the present invention is not limited to this.

Then, a total of four holes are formed at two positions in the swing member 22 and the vertical portion 2a of the moving side frame 2 respectively, and the pins 23 are inserted through these holes, so that the swing member 22 is By swinging, the holding member 21 can swing.
In this way, as shown in FIG. 6 (a), the inner surface of the bathtub side wall is inclined, and even with respect to the side wall of the bathtub whose thickness increases toward the bottom, the holding member 21 is inclined to the inner surface of the bathtub side wall. Along so that the clamping mechanism of the bathing aid can be more firmly attached to the bathtub side wall.

Also, a hole (drawing number 24 in FIG. 7) formed in the vertical portion 2a of the moving side frame is formed to have a larger diameter in the horizontal direction than the diameter in the vertical direction, so that the play is made larger, and By turning within a relatively small angle, the holding member 21 can be made to be able to swing.
In this way, the holding member 21 is provided on the inner surface of the curved side wall even in the vicinity of the corner of the bathtub whose inner surface of the bathtub is curved in plan view as shown in FIG. This makes it possible to incline so that the clamping mechanism of the bathing aid can be more firmly attached to the bathtub side wall. In addition, it can be more firmly attached to the bathtub side wall by the clamp mechanism also on the inner surface of the side wall that is curved in a plan view other than at the corners.

Next, a description will be given of moving operation means for moving the moving side frame 2 with respect to the vertical portion 11a of the holding member 11 of the main body frame 1. In this embodiment, since two moving-side frames are provided, two moving operation means are also provided.
The moving operation means includes a screw member 3, a guide 4, a lever 5, and a spring 6, as described below.

  As described above, the screw member 3 is engaged with the main body frame 1 such that the screw shaft portion 31 is rotatable and movable in the axial direction. As shown in FIG. 8, a knob (knob) 32 is formed on the head of the screw member 3 and is exposed outside the main body frame 1 (see FIGS. 1 to 4), and the knob 32 is pushed in. By pulling out or pulling out, the screw shaft 31 of the screw member 3 can be advanced or retracted in the axial direction with respect to the main body frame 1, and the screw shaft 31 of the screw member 3 can be rotated by turning the knob 32. Can be rotated.

  The guide 4 is a member having a substantially U-shaped cross section as can be seen from FIG. 11, and as can be seen from FIG. 9, the outer surface of a portion corresponding to the bottom of the substantially U shape and one side portion of the substantially U shape. Is fixed to an end of the horizontal portion 2b of the movable frame 2 closer to the knob 32 on the lower outer surface of the portion corresponding to. As described above, the end of the horizontal portion 2b of the movable frame 2 closer to the knob 32 has a shape in which one of two left and right sides forming a substantially U-shaped cross section is missing. ing.

  As can be seen from FIG. 9, the guide 4 has a semicircular cross section at a portion corresponding to a substantially U-shaped lower portion, and has an inner diameter slightly larger than the outer diameter of the screw shaft portion 31 of the screw member 3. The screw shaft 31 of the screw member 3 can be guided movably in the axial direction on the inner surface of the portion corresponding to the lower part of the substantially U-shape.

  As can be seen from FIG. 11, the lever 5 is disposed such that a portion including one end thereof is accommodated in a portion corresponding to the inside of the substantially U-shaped guide 4, and a portion including the other end is provided. The guide 4 is disposed so as to be exposed from a portion corresponding to the inside of the substantially U-shape. As shown in FIG. 8, a portion including one end of the lever 5 may partially protrude from a portion corresponding to the substantially U-shaped portion of the guide 4.

The lever 5 is pivotally supported by the guide 4 as can be seen from FIGS. That is, the lever 5 can rotate around the pin 7 inserted into a hole (no drawing number) formed at an upper portion of a portion corresponding to two substantially U-shaped side portions of the guide 4. Has become.
In addition, 41 is a side guide piece, which will be described later.

  As can be seen from FIG. 11, the upper end of the pin 7 is exposed from a portion corresponding to the upper side of the substantially U-shaped portion of the guide 4, and a spring 6 having a torsion coil spring function is provided on the exposed portion. 8, one end of the spring 6 is locked to the guide 4 and the other end is locked to the lever 5, respectively. Then, the end face of one end of the lever 5 is urged by the screw shaft 31 of the screw member 3 by the torsion coil spring function of the spring 6 (see FIG. 8A). The spring 6 is provided with a flange on the pin 7 so as not to come off the pin 7.

As can be seen from FIG. 11, the lever 5 has a thread (female thread) that is screwed into the male screw of the screw shaft part 31 of the screw member 3 on one end face. When the lever 5 is urged against the screw shaft 31 of the screw member 3, the threaded end surface of the lever 5 is screwed into the screw shaft 31 (see FIGS. 8A and 9). ].
In the following, the screwing of the screw shaft portion 31 of the screw member 3 with the threaded end surface of one end of the lever 5 will be simply referred to as the screwing of the screw shaft portion 31 of the screw member 3 with the lever 5. There is that.

To release the screw engagement between the screw shaft portion 31 and the lever 5, the end of the lever 5 where the thread is not formed (hereinafter referred to as “the other end”) is pressed, and the lever 5 is centered on the pin 7. By rotating the lever 5 to separate the end face of the lever 5 where the thread is formed from the screw shaft portion 31 (see FIGS. 8A and 8B).
When the other end of the lever 5 is not pressed, the end face of the one end of the lever 5 is urged by the spring 6 against the screw shaft 31 of the screw member 3. The threaded end faces of the shaft 31 and the lever 5 are screwed together.

  The number of screw threads formed on the end face of the lever 5 is about 1 to 10 because if the number of threads increases, it becomes difficult to screw the lever 5 and the screw shaft portion 31 together. In addition, it is desirable to add round (round) to both ends in the length direction of the end face of the lever 5 where the thread is formed (see FIG. 8).

As can be seen from FIGS. 8, 9, and 11, at a position corresponding to the inside of the substantially U-shaped lower portion of the guide 4, at a position where the screwing of the thread on the end face of the lever 5 and the screw shaft portion 31 is not hindered It is desirable to mount a side guide piece 41 having a semicircular cross section. By doing so, a cylindrical portion is formed by the side guide piece 41 and a portion corresponding to the substantially U-shaped bottom of the guide 4, and the screw shaft portion 31 of the screw member 3 is passed through the cylindrical portion. The screw member 3 is guided stably in the axial direction by preventing the screw shaft portion 31 from swinging.
As can be seen from FIG. 8, a stopper 33 is attached to the end of the screw shaft 31 of the screw member 3 so that the screw member 3 does not come out of the guide 4 when the screw member 3 is retracted. Is desirable.

  9 and 11, recesses 42 are formed on the same side (the knob 32 side of the screw member 3) in the middle of the portion corresponding to the two substantially U-shaped side portions of the guide 4. As shown in FIG. 9, the portion of the guide 4 below the concave portion 42 is accommodated in a portion corresponding to the substantially U-shaped cross section of the horizontal portion 2b of the moving side frame 2, and the portion above the concave portion 42. Are arranged so as to protrude from the cross section in a lateral direction (a direction parallel to the plane of the horizontal portion 11b of the holding member 11). One of the two side portions of the substantially U-shaped section of the main body frame 1 can enter the two concave portions 42 (FIG. 1, FIG. 2 and 4). The recess 42 may not be provided, but is preferably formed.

  As described above, the portion corresponding to the substantially U-shaped upper portion of the guide 4 is arranged so as to protrude from the cross section corresponding to the substantially U-shaped of the movable side frame 2, as shown in FIGS. 1 and 2. The section of the main body frame 1 having a substantially Γ-shaped cross section protrudes from below the shorter side. Therefore, the pin 7 mounted on the portion corresponding to the upper portion of the substantially U-shaped portion of the guide 4, the spring 6 mounted on the pin 7, and the other end of the lever 5 have a substantially Γ-shaped cross section of the main body frame 1. Is always exposed from below the shorter side.

As can be seen from FIG. 10, the height of the roof portion 1 a of the main body frame 1 is the height at which the horizontal portion 2 b of the movable frame 2 is stored between the upper surface of the horizontal portion 11 b of the holding member 11. In this case, the horizontal portion 2b of the movable frame 2 must be able to move (slide) on the upper surface of the horizontal portion 11b of the holding member 11 of the main body frame 1. Also, between the lower edge of the shorter side of the two sides of the substantially Г (gamma) -shaped section of the body frame 1 and the upper surface of the horizontal section 11b of the holding member 11 However, it is necessary to provide a gap that does not hinder the movement of the guide 4.

As described above, the other end of the lever 5 is exposed from below the lower side of the portion of the main body frame 1 having a substantially Γ-shaped cross section, so that the screw To release the screw engagement between the shaft portion 31 and the threaded end surface of one end of the lever 5, the other end of the lever 5 is pressed, and the lever 5 is rotated about the pin 7. This can be done at any time.
When this pressing is stopped, the threaded end surface of the lever 5 is urged against the screw shaft 31 of the screw member 3 by the action of the spring 6, and the screwing is restored.

  In this embodiment, as can be seen from FIGS. 1 and 2, the other ends of the two levers 5 that can release the screwing of the screw shaft portion 31 and the lever 5 are both in the region between the two main body frames 1. However, if there is no obstacle to the operation of pressing the other end of the lever 5 to release the screw engagement, the other end of the two levers 5 or one of the levers 5 is connected to the two You may make it arrange | position in the area | region between main body frames. To do so, of the two side portions of the body frame 1 having a substantially Г (gamma) -shaped cross section, the side portion having the shorter height (vertical length) is selected. The surface must face between the two body frames 1.

Next, the operation of the moving operation means will be described.
When the screw shaft 3 of the screw member 3 and the lever 5 are screwed together and the knob 32 of the screw member 3 is pushed to move the screw member 3 in the screw shaft direction, the guide 4 moves in the axial direction of the screw shaft portion 31. Since it moves (see FIG. 9), the moving frame 2 to which the guide 4 is attached also moves, and the horizontal portion 2b of the moving frame 2 is positioned on the upper surface of the horizontal portion 11b of the holding member 11 of the body frame 1. 3 (moving from right to left in FIG. 3), the distance between the vertical portion 11a of the holding member 11 and the holding member 21 of the moving frame 2 is increased.
As described above, the main body frame 1 has a substantially Г (gamma) -shaped cross section, and one of the two side portions has a shorter height (vertical length) than the other. It is not possible to prevent the guide 4, the lever 5, and the spring 6 projecting from the cross section corresponding to the substantially U-shaped section of the horizontal section 2b of the moving frame 2 from moving in the axial direction of the screw shaft 31 of the screw member 3. Absent.

  Similarly, when the knob 32 is pulled in the opposite state in the screwed state, the movement of the knob 32 is reversed, and the moving side frame 2 is moved to the upper surface of the horizontal portion 11b of the holding member 11 of the main body frame 1. 3 (moving from left to right in FIG. 3), and the distance between the vertical portion 11a of the holding member 11 and the holding member 21 of the moving frame decreases. In this case, as can be seen from FIG. 3, it is possible to move until the vertical portion 2 a of the moving side frame 2 contacts the left end of the horizontal portion 11 b of the holding member of the main body frame 1. Therefore, at this time, the distance between the vertical portion 11a of the holding member 11 and the holding member 21 of the movable frame 2 must be smaller than the thickness of the side wall of the bathtub 200.

  When the knob 32 is pushed to move the screw member 3 in the screw axis direction in a state where the screw shaft portion 31 of the screw member and the lever 5 are released, the screw shaft portion 31 of the screw member 3 is guided by the guide 4. The moving side frame 2 to which the guide 4 is attached does not move since the screwing is released.

  The same applies when the screw member 3 is moved (retracted) in the axial direction of the screw shaft portion 31 by pulling the knob 32 in a state in which the screw engagement is released, so that the horizontal portion of the holding member 11 of the main body frame 1 is similar. The distance between 11a and the holding member 21 of the moving side frame 2 does not change. When a stopper is attached to the tip of the screw shaft 31 of the screw member 3, if the knob 32 is continuously pulled, the stopper 33 attached to the tip of the screw shaft 31 of the screw member 3 hits the guide 4. The screw member 3 does not fall off the main body frame 1.

  When the knob 32 is turned or turned in the opposite direction in a state where the screw shaft portion 31 of the screw member 3 and the lever 5 are screwed together, the screw member 3 turns or turns in the opposite direction, and the guide 4 turns the screw shaft. And the moving side frame 2 attached to the guide 4 can be moved on the upper surface of the horizontal portion 11b of the holding member 11 of the main body frame to move forward and backward. By rotating the knob 32 or rotating in the opposite direction, the distance between the vertical portion 11a of the holding member 11 and the holding member 21 supported by the movable frame 2 can be finely adjusted.

Hereinafter, an example of an operation procedure for attaching and detaching the clamp mechanism 100 of the bathing aid of the present invention to and from a bathtub side wall will be described. An auxiliary bathing tool is mounted on the main body frame of the clamp mechanism 100. In addition, the work procedure of attachment and detachment is not limited to this example.
The clamp mechanism 100 of the above-described embodiment has two main body frames 1 and two moving-side frames 2, and includes two pairs of the main body frame 1 and the moving-side frame 2. In order to omit the work procedure, one body frame 1 and one moving side frame 2 that is paired with the body frame 1 will be described below.
The screwing of the screw shaft 31 of the screw member 3 with the threaded end face of the lever 5 is performed by screwing the screw member 3 with the lever 5, screwing the screw shaft 31 with the lever 5, or simply screwing. Sometimes it is.

・ Installation procedure (0)
After the end of the lever 5 where the thread is not formed on the end face (hereinafter, this end is referred to as “the other end”) to release the screw engagement between the screw member 3 and the lever 5, the knob 3 (in FIG. 3, the knob 32 moves to the right, and a part of the screw shaft portion 31 of the screw member 3 is exposed from the main body frame 1. At this time, the screw member 3 and the lever 5 are screwed together. (The moving side frame 2 does not move because it has been released.)
Next, the pressing of the other end of the lever 5 is stopped (the pressing is released), and after the screw member 3 and the lever 5 are screwed together, the knob 32 is pressed. At this time, the moving frame 2 moves, and the distance between the vertical portion 11a of the holding member 11 of the main body frame 1 and the holding member 21 of the moving frame 2 increases (in FIG. 3, the moving frame 2 moves in the left direction). Move to).
In the following, the distance between the vertical portion 11a of the holding member 11 and the holding member 21 of the movable frame 2 will be referred to as "spacing L".
By this operation, the interval L is increased to about 1.5 times the thickness width of the bathtub side wall with a margin beforehand. Usually, since the clamp mechanism is removed from the bathtub side wall after the previous use of the bathing aid, the interval L is sufficiently wide. In such a case, there is no need to perform the above operation (see “Removal procedure (2)” described later).
(The operation of increasing the interval L includes an operation of pulling the knob 32 forward and an operation of pressing the knob 32 forward, but does not require an operation of rotating the knob, so that the operation can be performed at once in a short time.)

・ Installation procedure (1)
The clamp mechanism is installed so that the holding member 11 of the main body frame 1 and the holding member 21 of the moving side frame 2 straddle the bathtub side wall. At this time, the horizontal portion 11b of the holding member 11 is in contact with the upper surface of the bathtub side wall. At this time, the pressing of the end of the lever 5 may be stopped, and the screw member 3 and the lever 5 may be screwed.
(Because the interval L is sufficiently large, in the course of this procedure, it is possible to prevent the side wall of the bathtub from being damaged, or to interrupt the work due to a liner of a holding member sticking to the side wall of the bathtub. Does not need to grip the vertical portion 2a of the moving side frame 2, so that the hands do not have to be immersed in the hot water in the bathtub.)

・ Installation procedure (2)
In a state where the screw member 3 and the lever 5 are screwed together (a state in which the pressing of the end of the lever 5 is stopped), the knob 32 is pulled forward (pulled to the right in FIG. 3). At this time, the moving side frame 2 moves, and the interval L becomes narrower, and becomes almost the same as the thickness of the bathtub side wall.
[The operation of reducing the distance L between the holding members to approach the thickness width of the bathtub side wall is only to pull the knob 32 of the screw member in the axial direction of the screw shaft portion 31 (from left to right in FIG. 3), Since the knob 32 is not rotated, the operation can be performed at once in a short time. ]

・ Installation procedure (3)
Next, in a state where the screw member 3 and the lever 5 are screwed together, the knob 32 of the screw member is rotated several times to move the holding member 21 of the moving side frame to further reduce the distance L, The vertical portion 11a of the holding member 11 of the frame 1 and the holding member 21 supported by the moving side frame 2 tighten the bathtub side wall, and fix the clamp mechanism to the bathtub side wall.
[Since the interval L has already become almost close to the thickness of the side wall of the bathtub in the installation procedure (2), the knob 32 is rotated several times in the same direction, and the interval L is further narrowed. The side wall of the bathtub can be tightened by the vertical portion 11a of the holding member of the frame 1 and the holding member 21 of the moving side frame 2, and the clamp mechanism can be firmly fixed. This operation can be easily performed in a short time because the knob is not rotated several tens of times in the same direction. Further, it is possible to avoid the damage to the bathtub side wall due to repeated rotation while the knob is rotated several tens times in the same direction as in the conventional clamp mechanism. ]
After the work of the mounting procedure (3) is completed, the bather can use the bathing aid. At this time, the screw member 3 and the lever 5 remain in a screwed state (a state in which the pressing of the end of the lever 5 is released).

Next, an example of a procedure for removing the clamp mechanism 100 of the present invention from the bathtub side wall will be described.
・ Removal procedure (1)
With the screw member 3 and the lever 5 screwed together, the knob 32 of the screw member 3 is rotated several times in the direction opposite to the rotation in the above-described mounting procedure (3), and By moving the holding member 21, the distance L is increased so as to be slightly larger than the thickness of the bathtub side wall. As a result, a slight gap is generated between the holding member 21 of the moving frame 2 and the inner surface of the bathtub side wall.
(This operation also can be easily performed in a short time because the knob does not rotate the knob several tens of times in the same direction.)

・ Removal procedure (2)
After the other end of the lever 5 is pressed to release the screw engagement between the screw member 3 and the lever 5, the knob 32 of the screw member 3 is pulled forward (pulled to the right in FIG. 3). At this time, the screw member 3 moves (to the right in FIG. 3), and the screw shaft portion 31 is exposed from the main body frame 1. Since the screwing is released, the moving side frame 2 does not move. Therefore, the interval L does not change.
(This operation can be easily performed in a short time at a stroke because the knob 32 is simply pulled in the hand without rotating the screw.)

・ Removal procedure (3)
The pressing of the other end of the lever 5 is stopped, and the knob 32 of the screw member 3 is pushed in the axial direction (from right to left in FIG. 3) in a state where the screw member 3 and the lever 5 are screwed into each other. (From the right side to the left side in FIG. 3), and the interval L is expanded to about 1.5 times the thickness width on the side wall of the bathtub.
(Because this operation only slides the horizontal portion 2b of the moving side frame 2 on the horizontal portion 11b of the holding member 11 by pushing the knob 32 in the axial direction without rotating the tightening screw. It can be easily done in a short time.)

-Removal procedure (4):
An appropriate part of the bathing aid is grasped at several places, and the clamp mechanism is pulled up from the bathtub side wall. The tub from which the clamp mechanism has been removed can be covered.
(Because the distance L is already large, it is possible to avoid interruption of the work due to the liner or the like of the holding member sticking to the side wall of the bathtub during the lifting. (Because there is no need to grip the portion 2a, it is not necessary to immerse the hands in the hot water in the bathtub.)

In the above embodiment, the clamp mechanism is provided with two main frames and two movable frames. However, the clamp mechanism includes one main frame and one movable frame, and one narrow frame is formed by one main frame. It is obvious that the bathtub side wall can also be clamped as a clamping mechanism of a bathing aid that supports the holding member and supports one holding member with one moving-side frame. Such an embodiment is suitable for attaching a handrail as a bathing aid.
Alternatively, the same applies to a clamping mechanism of a bathing assisting tool in which two body frames 1 each support one holding member, and two moving-side frames each support one holding member, It is clear that the bathtub side wall can be pinched.

The holding members and the moving operation means other than the frame and the liner that constitute the clamp mechanism of the present invention can be generally made of metal, and are made of a material having high strength and less rust (for example, stainless steel). Are suitable.
Each member constituting the clamp mechanism of the present invention can be appropriately changed without departing from the technical idea of the invention that can be read from the claims and the entire specification.
