<Safety device>

The elevating device 30 provided in the bathing apparatus 1 is configured to elevate the seating portion 20 using the wire 314. In such a configuration, when the wire 314 is cut, there is a concern that the seating portion 20 may suddenly fall. Therefore, the bathing apparatus 1 is provided with a safety device for preventing this sudden drop. Hereinafter, this safety device will be described.
(First embodiment)

  FIG. 5 is a perspective view showing a simplified configuration around the safety device 60 of the first embodiment provided in the bathing apparatus 1 according to the embodiment of the present invention. As shown in FIG. 5, components constituting the safety device 60 are provided on the lifting body 33.

  The safety device 60 includes a frame 61 having a substantially rectangular shape when viewed from the front. The frame 61 is attached to a rotating shaft 332 whose left and right sides protrude from both ends of the roller 331. When viewed from the side, the frame 61 is bent at the rotating shaft 332 (see FIG. 6 described later). The frame 61 is formed of, for example, a metal wire (wire) or the like. The frame 61 is attached to the rotating shaft 332 so as to be rotatable about the rotating shaft 332, and is an example of the rotating portion of the present invention.

  One end of a tension spring 62 is attached to each end of the upper side 61 a of the frame 61. The other ends of the two tension springs 62 are both attached to a cover member constituting the elevating body 33. The frame 61 is biased by the tension spring 62 in the direction of rotation about the rotation shaft 332. In FIG. 5, the frame 61 is urged in a direction that rotates clockwise. The tension spring 62 is an example of an urging member of the present invention.

  A substantially cylindrical member 63 formed of, for example, resin or metal is provided at a substantially central portion of the upper side 61a of the frame 61. The substantially cylindrical member 63 is disposed on the back side with respect to the wire 314. For this reason, the substantially cylindrical member 63 is pressed against the wire 314 (assuming an uncut state) by the biasing force of the tension spring 62. The substantially cylindrical member 63 is an example of a pressing portion of the present invention, and is hereinafter referred to as a pressing portion 63. The pressing portion 63 may be the wire itself that constitutes the frame 61, but it is easier to avoid damage to the wire 314 if a member thicker than the wire is provided as in this embodiment.

  A projecting piece 64 is provided at a substantially central portion of the lower side 61b of the frame 61. The projecting piece 64 extends toward a place where the roller 331 and the support column 32 come into contact with each other. The protruding piece 64 can be formed using, for example, a thin metal plate (sheet metal). The protruding piece 64 is an example of the engaging portion of the present invention. The protruding piece 64 may be formed of, for example, a metal wire instead of a metal plate. When formed with a wire, it may have a hollow structure. Further, the protruding piece 64 may not be a thin plate but may be, for example, a wedge shape.

  Next, the operation of the safety device 60 of the first embodiment will be described with reference to FIG. In addition, FIG. 6 is a figure for demonstrating the effect | action of the safety device 60 of 1st Embodiment with which the bathing apparatus 1 which concerns on embodiment of this invention is equipped, Fig.6 (a) shows the state in which the wire 314 is not cut | disconnected. FIG. 6B shows a state where the wire 314 is cut. FIG. 6 is a schematic diagram assuming a state in which the safety device 60 is viewed from the side surface side.

  In a state where the wire 314 is not cut (the state shown in FIG. 6A), the frame 61 tries to rotate due to the urging force of the tension spring 62, but the pressing portion 63 comes into contact with the wire 314, so Rotation is prevented. For this reason, in the state where the wire 314 is not cut, the parts constituting the safety device 60 including the protruding piece 64 are not in contact with the support column 32, and the elevating body 33 smoothly moves along the support column 32. Moving. The protruding piece 64 is not in contact with the roller 331 as well.

  On the other hand, when the wire 314 is cut (when the state shown in FIG. 6B is reached), the pressing portion 63 is not pushed back from the wire 314, so that the frame 61 rotates around the rotation shaft 332 by the urging force of the tension spring 62. (Turns clockwise). With this rotation, the projecting piece 64 also rotates, and the projecting piece 64 enters between the support column 32 (the wall constituting the support column 32) and the roller 331. For this reason, a brake is applied to the dropping operation of the elevating body 33 that falls because the wire 314 is cut, and the elevating body 33 can be prevented from suddenly falling.

In the configuration of the present embodiment, the wire 314 is not cut, but the safety device 60 can be activated even when the wire 314 is loosened (slack) to some extent. However, since the bathing apparatus 1 includes the tension detection mechanism 50 as described above, the driving of the drive motor 311 can be stopped before the safety device 60 operates by adjusting the tension detection mechanism 50. That is, the safety device 60 can be activated only when the wire 314 is cut in principle.
(Second Embodiment)

  Next, the safety device of 2nd Embodiment is demonstrated. FIG. 7 is a perspective view showing a simplified configuration around the safety device 70 of the second embodiment provided in the bathing apparatus 1 according to the embodiment of the present invention. As shown in FIG. 7, components constituting the safety device 70 are provided on the lifting body 33.

  The safety device 70 includes a lever 71 (having an elongated plate shape) that is rotatably attached to the elevating body 33. The lever 71 is provided so as to be rotatable in a plane (in a vertical plane) parallel to the bottom surface 32a of the support column 32 formed in a substantially U-shape in cross section. The bottom surface 32 a is substantially parallel to the longitudinal side walls 10 a and 10 b (see FIG. 1) of the bathtub 10. Moreover, the lever 71 is an example of the rotation part of this invention.

  The lever 71 is biased by an unillustrated biasing member so as to rotate about the rotation shaft 71a. In FIG. 7, the lever 71 is urged so as to rotate counterclockwise. As the biasing member that applies a biasing force to the lever 71, for example, a torsion coil spring attached to the rotary shaft 71a may be used.

  A protrusion 72 is provided on one end side (upper end side) of the lever 71 in the longitudinal direction. The protruding portion 72 may be provided on the lever 71 by integral molding, or may be attached to the lever 71 using an adhesive, a fixture, or the like. The protrusion 72 is pressed against the wire 314 (assuming a state where it is not cut) by the above-described urging force with respect to the lever 71. The protrusion 72 is an example of the pressing portion of the present invention.

  A first engagement pin portion 73 is provided near one end in the longitudinal direction of the lever 71 (slightly closer to the rotation shaft 71a than the position where the projection 72 is provided). The first engaging pin portion 73 includes a first support bar 731 that is rotatably attached to the lever 71, a front end side of the first support bar 731, and a longitudinal direction of the first support bar 731. And a first engagement pin 732 that is slidably attached.

  The first support bar 731 is supported so that its longitudinal direction is parallel to the horizontal direction when the safety device 70 is not in operation. Further, the first support bar 731 is rotatable only in one direction (clockwise direction in FIG. 7) from this horizontal state. An urging member that urges the first support bar 731 in the counterclockwise direction may be provided, and in this embodiment, this is the case.

  The first support bar 731 and the first engagement pin 732 have stoppers 731a and 732a, respectively. In a state where the first engagement pin 732 is attached to the first support bar 731, a first compression spring 733 is disposed between the two stoppers 731 a and 732 a (the first compression spring 733 is the first compression spring 733. 1 is freely fitted to the support bar 731). The first engagement pin 732 is biased toward the outside by the first compression spring 733.

  Near the other end of the lever 71 in the longitudinal direction, a second engagement pin portion 74 is provided. The second engagement pin portion 74 has the same configuration as the first engagement pin portion 73, and includes a second support bar 741 (having a stopper 741a) and a second engagement pin 742 (stopper). 742a) and a second compression spring 743. Since these relationships are the same as those of the first engagement pin portion 73, detailed description thereof is omitted.

  The second support bar 741 is supported so that the longitudinal direction thereof is parallel to the horizontal direction when the safety device 70 is not in operation. Further, the second support bar 741 is rotatable only in one direction (clockwise direction in FIG. 7) from this horizontal state. Such a configuration is realized by using a biasing member that biases the second support bar 741 counterclockwise.

  A plurality of engagement holes (through holes) 321 into which the engagement pins 732 and 742 can be fitted are provided in the two side walls 32b and 32c of the support column 32, respectively.

  Next, the operation of the safety device 70 of the second embodiment will be described with reference to FIG. In addition, FIG. 8 is a figure for demonstrating the effect | action of the safety device 70 of 2nd Embodiment with which the bathing apparatus 1 which concerns on embodiment of this invention is equipped, FIG.8 (a) is a state in which the wire 314 is not cut | disconnected. FIG. 8B shows a state where the wire 314 is cut.

  In the state where the wire 314 is not cut (the state shown in FIG. 8A), the lever 71 tries to rotate by the urging force applied to the lever 71, but the protrusion 72 contacts the wire 314. Rotation is prevented. In a state where the wire 314 is not cut, the components constituting the safety device 70 are not in contact with the support column 32, and the elevating body 33 moves smoothly along the support column 32.

  On the other hand, when the wire 314 is cut (when the state shown in FIG. 7B is reached), the protrusion 72 is not pushed back from the wire 314, so that the lever 71 rotates around the rotation shaft 71a (counterclockwise). Rotate). By this rotation, the first engagement pin 732 moves in a direction approaching the first side wall 32 b of the support column 32. Further, the second engagement pin 742 moves in a direction approaching the second side wall 32 c of the support column 32.

  More specifically, the first engagement pin 732 moves in the direction in which the tip thereof faces downward, and the second engagement pin 742 moves in the direction in which the tip thereof faces upward, but the safety device 70 operates. Since the side walls 32a and 32b are arranged in the immediate vicinity of the engaging pins 732 and 742 in a state where the movement is not performed, the movement is not large.

  When the engagement pins 732 and 742 approach the side walls 32b and 32c, if the engagement holes 321 are located at the approached positions, the engagement pins 732 and 742 are fitted into the engagement holes 321 as they are. At this time, the support bars 731 and 741 rotate slightly in the clockwise direction and become parallel to the horizontal direction. The engagement between the engagement pins 732 and 742 and the engagement hole 321 can apply a brake to the dropping operation of the elevating body 33 that falls because the wire 314 is cut, and can prevent the elevating body 33 from suddenly falling.

  On the other hand, when the engagement pins 732 and 742 approach the side walls 32b and 32c, if there is no engagement hole 321 at the approached position, the engagement pins 732 and 742 are pressed against the side walls 32a and 32c. Become. However, since the wire 314 is cut, the elevating body 33 also falls, and each engagement pin 732 and 742 reaches a position facing the engagement hole 321. At this position, the engaging pins 732 and 742 are fitted into the engaging holes 321 as the lever 71 rotates. At this time, the support bars 731 and 741 rotate slightly in the clockwise direction and become parallel to the horizontal direction. The engagement between the engagement pins 732 and 742 and the engagement hole 321 can apply a brake to the dropping operation of the elevating body 33 that falls because the wire 314 is cut, and can prevent the elevating body 33 from suddenly falling.

In the configuration of the present embodiment, the wire 314 is not cut, but the safety device 70 can be operated even when the wire 314 is loosened (slack) to some extent. However, since the bathing apparatus 1 includes the tension detection mechanism 50 as described above, the driving of the drive motor 311 can be stopped before the safety device 70 is activated by adjusting the tension detection mechanism 50. That is, the safety device 70 can be operated only when the wire 314 is cut in principle.
