Now, the said bathtub stand 1 uses the suction cup 14 attached to the leg part 3, and uses this bathtub stand 1 fixed to the bottom of a bathtub, the floor of a bathroom, etc. At the time of use, the bathtub base 1 adjusts the height of the leg portion 3 appropriately according to the user's physique and usability. At the time of this height adjustment, the chain 29 coupled to the suction cup 14 becomes too loose or too tight, so that the pin 30 is moved into the engagement hole corresponding to the degree of expansion / contraction of the leg 3. Change to any of 31 and engage and adjust accordingly.
For example, when the leg portion 3 is changed to the pin hole 15A from the pin hole 15B to the maximum extension state, the pin 30 is removed from the engagement hole 31B and engaged with the engagement hole 31A. On the other hand, when the leg portion 3 is changed to the pin hole 15D from the pin hole 15B to the most contracted state, the pin 30 is removed from the engagement hole 31B and engaged with the engagement hole 31D. Detachment and remounting of the pin 30 may be performed simply by picking and turning the knob 40A of the pin 30 with a finger, and hardly requiring fingertip force. When the pin 30 is rotated, the vertical key 41A of the pin 30 is guided by the step 43, and the chain 29 is rotated by sliding the guide groove 40C provided in the guide portion 40B. Since the direction is guided in one direction, the rotation operation of the pin 30 can be easily grasped, and attachment / detachment and attachment can be performed quickly and easily.

  Conventionally, a ring is attached to the chain in place of the pin 30, and a hook is provided in the base portion in place of the engagement hole 31, and the ring is pulled and hooked on the hook. The fingertip force is required when pulling the ring. On the other hand, the bathtub base 1 has a very simple configuration in which the pin 30 is rotated to be inserted into and removed from the engagement hole 31, and there is no need to pull the pin 30 when the pin 30 is inserted or removed. , Requires little fingertip power.

Next, the use of the bathtub base 1 will be described.
When using the bathtub base 1 in a bathtub, as shown in FIG. 9, the bathtub base 1 is arrange | positioned and used so that the short side of the base part 2 and the long side of the bathtub 51 may become substantially parallel. On the other hand, when releasing the fixing by the suction cup 14 for moving the bathtub base 1 or the like, the operator places a hand on the open handle 32 attached to the long side edge of the base part 2 from the outside of the bathtub 51, Pull the arm upward as it is. Then, the open handle 32 rotates so as to open toward the outside of the base portion 2 with the rotation shaft 32A as an axis center (see FIG. 2).

  Here, as shown in FIG. 4, the chain 29 is guided by a guide 29, and further guided by a guide protrusion 32B protruding from the lower edge of the open handle 32, and then united. The pins 30 are connected to the guide grooves. On the other hand, the pin 30 is fixed to the lower surface of the pedestal 2 by being locked in the appropriate locking hole 31 (locking hole 31B in FIG. 4) corresponding to the degree of expansion / contraction of the leg 3 as described above. The chain 29 is in a state in which the other end connected to the pin 30 fixed to the base 2 is fixed while one end is coupled to the suction cup 14 while maintaining an appropriate tension. Therefore, when the open handle 32 is rotated, the intermediate portion of the chain 29 is pulled toward the outside of the base portion 2 by the guide projection 32B, and the chain 29 is substantially guided by the guide 29 while the end portion of the suction cup 14 is substantially removed. Pulling up vertically, the end of the suction cup 14 is turned up. As a result, the vacuum inside the suction cup 14 is broken, and the fixing by the suction cup 14 is released, so that the bathtub base 1 is easily peeled from the bottom of the bathtub.

In the present embodiment, the positions of the engagement holes 31A to 31D of the pedestal 2 are stretched to such an extent that the chain 29 is pulled up by the open handle 32 at the degree of expansion and contraction corresponding to the pin holes 15A to 15D of the leg 3. It is set to a position that will cause
The chain 29 is guided by a guide 29A provided on the lower surface of the base 2 so as to rise substantially vertically from the end of the suction cup 14, so that the end of the suction cup 14 is pulled in an oblique direction. In comparison, the stroke required for turning up the end of the suction cup 14 is short. For this reason, the force for turning up the suction cup is suitably applied to the end of the suction cup 14 with little movement without waste.
Further, since the vacuum of the suction cup 14 is broken by the rotation of the open handle 32, the bathtub base 1 is placed on the open handle 32 by putting the finger on the open handle 32 without putting force on the fingertip, such as grasping the finger. The end of the suction cup 14 can be turned up by a natural operation of lifting, and a large force is not required to release the fixing of the bathtub base 1.
Moreover, the open handle 32 is attached to the long side edge of the base part 2, and when the bathtub base 1 is used in the bathtub 51 as described above, the bathtub base 1 is not changed from the outside of the bathtub 51. Can be lifted. That is, when the open handle 32 is attached to the short side edge of the pedestal 2, in order to lift the bathtub pedestal 1 from the outside of the bathtub 51, the work must be performed with an unnatural posture with a twisted waist. If a person enters the bathtub 51, there is no need to take an unnatural posture, but extra work such as draining the water in the bathtub 51 is required. In addition, when an operator enters the bathtub 51 to work, the distance from the inner surface of the bathtub 51 to the side edge of the bathtub base 1 is short and the work space is narrow, so that the work is difficult. The thing of the structure rotated so that 32 may be opened toward the outer side of the base part 2 may produce malfunctions, such as a hand or the open handle 32 hitting the inner surface of the bathtub 51. FIG.

  In addition to the above embodiment, the plurality of engagement holes 31 are not limited to be arranged in a line, and may be arranged in a staggered manner, for example. Further, the engagement hole 31 may be disposed on the side surface, the upper surface, or the like other than the lower surface of the base portion 2. Further, the open handle 32 may be attached to the short side edge of the pedestal 2, and in this case, it is desirable to use it in the bathtub 51 such as a plane shape circle or a plane shape square. Moreover, the bathtub base 1 of the present invention uses, for example, a synthetic resin as a material, and the upper surfaces of the suction cup 14 and the lid mold upper portion 5 as a material of rubber or elastomer.
