  By the way, when adjusting the vertical height of the adjuster bolt device shown in the conventional example, the head of the hexagon bolt grounded to the ground is rotated around the axis of the hexagon bolt, and the screw of the hexagon bolt is screwed. Since the vertical height is adjusted by changing the insertion length, it is necessary to rotate the hexagon bolt around the axis. At this time, in order to rotate this hexagon bolt around the axis, a tool such as a spanner is fitted from the side of the head of the grounded hexagon bolt, and the tool is rotated around the axis about the axis of the hexagon bolt. In order to carry out such work, a large space is required around the adjuster bolt device in the range where the entire length of the tool such as a spanner is a radius with the axis of the bolt as the center.

  In particular, when adjusting the vertical height of an adjuster bolt device installed on a supported body having a bottom surface such as a bathroom floor pan, it is necessary to perform such a work under the supported body, It is very difficult to perform such work while in a diving position. Therefore, it is desired that adjustment using an electric power tool is possible, but there is no general electric power tool that can be fitted from the side of the head of the hexagon bolt and rotated around the axis of the hexagon bolt. . For this reason, the operator performs the work of inserting a tool such as a spanner from the side of the head of the hexagon bolt and rotating it about the axis while keeping an unreasonable posture lying below the bathroom floor pan and lying on the ground. There was a problem that workability was very bad.

  The present invention has been made in view of the above-described conventional problems, and an object thereof is to require a wide space around the adjuster bolt device when adjusting the vertical height of the adjuster bolt device.

It is formed in the same shape as the head of the bolt.

  The rotating core 3 is made of the same resin as that of the support portion 2, and the main body is constituted by a cylindrical shape that is long in the vertical direction. A female screw is threaded over the entire length in the vertical direction in the central hole 32 in the inside of the rotary core 3 so that the central shaft 22 on which the male screw described above is screwed can be screwed. . Grooves 31 are formed on the entire surface of the outer periphery of the rotating core 3 so as to extend to the upper and lower ends.

  The pedestal portion 4 is formed of the same resin as the support portion 2 and the rotary core material 3 and has a bottomed cylindrical shape that opens upward, and a cylindrical portion 41 into which the rotary core material 3 is inserted from above. It is composed of a grounding portion 43 having a substantially rectangular shape in plan view and extending outward from the lower end of the cylindrical portion 41 and having the back surface as a ground contact surface 42. The inner surface of the cylindrical portion 41 is a smooth surface so that the outer peripheral surface of the rotating core member 3 can be slidably contacted. The bottom surface of the cylindrical portion 41 is in contact with the lower end portion of the rotating core member 3 and is rotatable. It has a smooth surface. A plurality of ribs 44 are formed at the outer corner portion formed by the ground contact portion 43 and the cylindrical portion 41 (four locations in the present embodiment), thereby improving the strength. Further, as shown in FIGS. 1B and 4, a bulging portion 45 protruding outward is formed on the upper portion of the cylindrical portion 41. An adjustment shaft hole 46 through which the adjustment shaft 5 is inserted in the horizontal direction is formed in the bulging portion 45 so as to pass through both ends of the bulging portion 45. The adjustment shaft hole 46 is bulged. The center of the portion 45 communicates with the space inside the cylindrical portion 41. Further, a rectangular stopper locking hole 47 is formed on the side surface of the bulging tip of the bulging portion 45.

  The adjustment shaft 5 is formed of the same resin as described above, and is provided with a shaft portion 52 in which a screw portion 51 made of a male screw is threaded on the outer surface of the shaft, and provided at one end of the shaft portion 52 in plan view. A hexagonal screw head 53 and an adjustment shaft retaining piece 54 for retaining the adjustment shaft 5 in a state where the shaft portion 52 is inserted into the adjustment shaft hole 46 provided in the bulging portion 45 of the pedestal portion 4. And is composed of. A stopper locking recess 55 is formed in the screw head 53 on the axis of the adjustment shaft 5.

  The rotating core 3 is inserted into the cylindrical portion 41 of the pedestal portion 4 formed in this way, and the adjustment shaft 5 is inserted into the adjustment shaft hole 46 provided in the bulging portion 45 of the pedestal portion 4. In addition, at the communicating portion between the adjustment shaft hole 46 and the space inside the cylindrical portion 41, a screw portion 51 in which the male screw of the adjustment shaft 5 is screwed into the groove portion 31 formed on the outer peripheral surface of the rotating core member 3. Are engaged. Further, the support portion 2 is installed at the upper end of the rotating core member 3. Specifically, as described above, the central shaft 22 of the supporting portion 2 is screwed into the central hole portion 32 of the rotating core member 3. ing.

  The adjuster bolt device 6 of the present embodiment configured as described above adjusts the vertical height by operating the vertical drive unit 7 including the rotary core 3 and the adjustment shaft 5 so that the support unit 2 moves up and down. In detail, the operation is as follows.

  When the adjustment shaft 5 that is rotatably installed on the bulging portion 45 of the pedestal portion 4 is rotated around the horizontal axis, the groove portion 31 of the rotary core 3 that meshes with the screw portion 51 of the adjustment shaft 5 moves along the screw portion 51. To do. In short, the rotation of the adjustment shaft 5 that takes the axis in the horizontal direction and rotates about the axis causes the rotation core 3 that takes the rotation axis substantially orthogonal to the rotation axis of the adjustment shaft 5 to rotate about the vertical rotation axis. (See arrows a and b in FIG. 3). Next, by rotating the rotary core member 3 in this way, the support part 2 that is installed on the bathroom floor pan and cannot rotate is screwed or screwed (see arrow C in FIG. 3). More specifically, the central shaft 22 of the support portion 2 changes the screwing position with the central hole portion 32 of the rotating rotating core 3 so that the support portion 2 moves upward or downward. It has become. As shown in FIG. 1 (a), the support 2 has a certain amount of overlap between the rotary core 3 and the support 2 since the upper surface of the inner surface of the support 2 is in contact with the upper end of the rotary core 3. Adjustment is possible in the range up to the height that leaves the allowance (see FIG. 1A; reference A).

  As described above, the adjuster bolt device 6 configured as described above is installed at the lower part of the bathroom floor pan and supports the bathroom floor pan.

  The bathroom floor pan of the present embodiment is formed by FRP (Fiber Reinforced Plastics) press molding, and the floor pan joining portion provided on the support portion 2 of the adjuster bolt device 6 on the back surface of the bottom surface of the bathroom floor pan. The to-be-joined part (not shown) which fits in 23 is installed in several places.

  In installing the adjuster bolt device 6 on such a bathroom floor pan, the work is performed by inverting the bathroom floor pan upside down (that is, with the installation surface of the adjuster bolt device 6 facing up). The floor pan coupling portion 23 in the support portion 2 of the assembled adjuster bolt device 6 is fixed to the mated portion formed on the back surface of the bathroom floor pan facing upward. In this manner, with the plurality of adjuster bolt devices 6 fixed on the back surface of the bathroom floor pan, the front and back are further reversed (that is, the installation surface of the adjuster bolt device 6 is down) to a predetermined position. Arranged.

  The bathroom floor pan arranged at a predetermined position is not horizontal in the horizontal plane of the bathroom floor pan, or the height of the edge of the bathroom floor pan and the dressing room adjacent to the bathroom may be shifted. Therefore, it is necessary to adjust the height of the adjuster bolt device 6 to adjust the height of the bathroom floor pan.

  In making this adjustment, the operator works under the floor pan for the bathroom. At this time, the operator can adjust the height of the adjuster bolt device 6 only by rotating the adjusting shaft 5 of the adjuster bolt device 6 around the horizontal axis, that is, the vertical height of the bathroom floor pan. Therefore, by using a tool such as a nut driver or socket wrench, it is possible to extend the hand and return the wrist without changing the body position (without approaching the part where the adjuster bolt device 6 is installed) (driver The height can be adjusted only by rotating the shaft around the axis). In addition, if an electric tool such as a socket wrench for an electric screwdriver is used, such an operation of returning the wrist becomes unnecessary, and the vertical height can be easily adjusted in a short time.

  Here, even after the height adjustment is completed, the rotary core 3 and the adjustment shaft 5 may rotate due to vibration or the like, and the height of the adjuster bolt device 6 and the bathroom floor pan may change. Therefore, the rotation prevention stopper 8 is installed to lock the rotation of the rotating core 3 and the adjustment shaft 5. The rotation prevention stopper 8 includes a stopper body 81 having a substantially L shape in plan view and stopper locking claws 82 projecting from both ends of the stopper body 81 in a substantially right angle direction. This stopper locking claw 82 is inserted and locked in a stopper locking hole 47 formed in the pedestal portion 4 and a stopper locking recess 55 formed in the screw head 53 of the adjustment shaft 5. This prevents the rotation core 3 and the adjustment shaft 5 from rotating (see FIG. 4).

  As described above, the adjuster bolt device 6 of the present embodiment has a simple configuration and is formed in a shape that does not take a width. Therefore, it is necessary to install a plurality of adjuster bolt devices 6 on the lower surface of the bathtub floor pan. Even if there is, there is less space required for installation. Therefore, there is an advantage that the worker can easily work.

  The groove 31 on the outer peripheral surface of the rotating core member 3 can achieve the effect of the present invention if the groove 31 is vertically long only at a portion meshing with the adjustment shaft 5, but it can be rotated as in this embodiment. If the groove portion 31 is formed so as to extend over both ends of the core material 3, when the adjuster bolt device 6 is assembled, the upper and lower surfaces of the rotating core material 3 are not mistakenly assembled, so that the assemblability is further improved. Has the advantage.

  Next, another embodiment will be described with reference to FIG. Since the present embodiment is mostly the same as the embodiment shown in FIGS. 1 to 4, the same portions are denoted by the same reference numerals, description thereof is omitted, and different portions are mainly described.

  This embodiment is different from the above-described embodiment only in the floor pan coupling portion 23 of the support portion 2. The floor pan coupling portion 23 of the present embodiment has a protruding portion 23a projecting upward from the upper end of the support portion 2. The protrusion 23a has a male screw threaded on its side surface.

  The bathroom floor pan (not shown) of the present embodiment is formed by FRP press molding as in the above-described embodiment, and a support portion of the adjuster bolt device 6 is provided on the back surface of the bottom surface of the bathroom floor pan. The to-be-joined part (not shown) which can be screwed and installed in the floor pan joint part 23 (projection part 23a) provided in 2 is installed in several places. Thereby, the floor pan for bathrooms and the adjuster bolt device 6 can be fixed.

  As mentioned above, although this invention was demonstrated based on the floor pan for bathrooms of a system bath as an example of the to-be-supported body 1, the to-be-supported body 1 uses the adjuster bolt apparatus 6 of this invention also for things, such as furniture. Can be applied.

  Further, since the adjuster bolt device 6 of the present embodiment is made of resin, the unit price of the member itself can be lowered as compared with a steel member whose material cost has been increasing significantly in recent years. In addition, since the resin can be molded easily, it is possible to mold the shape of the floor pan coupling portion 23 according to the shape of the floor pan, and there are many design advantages. Furthermore, a standard hexagon bolt can be used for the adjusting shaft 5, and in this case, the cost can be further reduced.

  Of course, even if the adjuster bolt device 6 is made of steel, the same effect as in the present invention can be obtained, but in this case, although the strength is improved as compared with that made of resin. However, on the other hand, the cost increases, and there arises a problem that it becomes difficult to form the floor pan joint portion in accordance with the shape of the floor pan.
