In the state ofFig. 7 , thethird protrusions 70 of the third engagingmember 67 respectively abut on thefirst protrusions 68 of the pair of first engagingmembers 55. Therefore, the pair of first engagingshafts 53 are retained at an intermediate position slightly protruding from both sides of theback member 50. Similarly, thefourth protrusions 71 of the third engagingmember 67 respectively abut on thesecond protrusions 69 of the pair of second engagingmembers 56. Therefore, the pair of secondengaging shafts 54 are retained at an intermediate position slightly protruding from both sides of theback member 50. -
Fig. 8 shows the state of theback member 50 after the operation click 72 of the third engagingmember 67 is operated to move the third engagingmember 67 to a lower position and thefirst operation members 61 and thesecond operating members 62 are operated to move the first and second engagingmembers back member 50. In the illustrated state, thethird protrusions 70 andfourth protrusions 71 of the third engagingmember 67 are located at a displaced position from thefirst protrusions 68 of the pair of first engagingmembers 55 and thesecond protrusions 69 of the pair of secondengaging members 56, respectively. Therefore, the pair of first engagingshafts 53 and the pair of secondengaging shafts 54 are brought to a retracted position completely retracted from both sides of theback member 50 into theback member 50. - Hereinafter, the
base member 10 will be described with reference toFigs. 9 and 10 . Arecess region 22 recessed to a predetermined depth is formed in the respective inner wall surfaces of the pair of rear standingwall portions 12 of thebase member 10. The two first shaft holes 23 and the two second shaft holes 24 are provided in therecess regions 22. The two second shaft holes 24 are located at an equal distance from one of the first shaft holes 23 which is located above, and the two first shaft holes 23 are located at an equal distance from one of the second shaft holes 24 which is located forward (on the left side inFig. 9 ). - As shown in
Fig. 9 , a cylindrical part of thefront guard portion 15 is accommodated in a columnar recess of thepillar portion 14. Thepillar portion 14 has a fixedclick 17 protruding upward from the bottom of the columnar recess. Thefront guard portion 15 has an engagingpiece 19, and the engagingpiece 19 has an engaginghole 18 through which the engagingpiece 19 can be anchored to the fixedclick 17. The engagingpiece 19 is biased by aspring 21 in a direction in which the engagingpiece 19 is anchored to the fixedclick 17. Thefront guard portion 15 has anoperation button 20 for performing an operation of moving the engagingpiece 19. - In the state of
Fig. 9 , the fixedclick 17 of thepillar portion 14 and the engagingpiece 19 of thefront guard portion 15 are anchored to each other so that thefront guard portion 15 cannot be detached from thepillar portion 14. By pressing thepush button 20 in the state ofFig. 9 , the anchored state between the engagingpiece 19 and the fixedclick 17 is released so that thefront guard portion 15 can be detached from thepillar portion 14. -
Figs. 11 through 14 show the bath chair with theback member 50 in various positions. Each state will now be described. - First, in the state of
Fig. 11 , the first engagingshaft 53 fits in the upperfirst shaft hole 23, the second engagingshaft 54 fits in the rear uppersecond shaft hole 24, and theback member 50 is inclined forward until theback member 50 becomes approximately parallel to thebase member 10.Fig. 11 shows the form of the bath chair while not in use, that is, a compact folded form of the bath chair. - The second
engaging shaft 54 is retracted by operating thesecond operation member 62 in the state ofFig. 11 . This operation causes thesecond protrusion 69 of the second engagingmember 56 and thefourth protrusion 71 of the third engagingmember 67 to abut on each other. Therefore, the second engagingshaft 54 is retained in the intermediate position between the protruding position and the retracted position. In other words, in this intermediate position, the second engagingshaft 54 is removed from thesecond shaft hole 24, but protrudes from both sides of theback member 50 to such a height that the second engagingshaft 54 cannot be removed from therecess region 22 provided in each of the respective inner surfaces of the pair of rear standingwall portions 12. In this state, theback member 50 is pivoted backward around the first engagingshaft 53 in order to obtain the state shown inFig. 12 . - In the state of
Fig. 12 , the second engagingshaft 54 fits in the front lowersecond shaft hole 24 and theback member 50 is inclined slightly backward so that the bath chair can be used as a chair. The first engagingshaft 53 is retracted by operating thefirst operation member 61 in the state ofFig. 12 . This operation causes thefirst protrusion 68 of the first engagingmember 55 and thethird protrusion 70 of the third engagingmember 67 to abut on each other. Therefore, the first engagingshaft 53 is retained in the intermediate position between the protruding position and the retracted position. In other words, in this intermediate position, the first engagingshaft 53 is removed from thefirst shaft hole 23, but protrudes from both sides of theback member 50 to such a height that the first engagingshaft 53 cannot be removed from therecess region 22. In this state, theback member 50 is pivoted backward around the second engagingshaft 54 in order to obtain the state shown inFig. 13 . - In the state of
Fig. 13 , the first engagingshaft 53 fits in the lowerfirst shaft hole 23, and theback member 50 is in a largely backward inclined state. By operating thefirst operation member 61 in the state ofFig. 13 , the first engagingshaft 53 is removed from thefirst shaft hole 23. In this state, theback member 50 is pivoted further backward, whereby the state shown inFig. 14 is obtained. In the state ofFig. 14 , the back surface of theback member 50 abuts on a rearend abutting portion 25 of thebase member 10, whereby the position of theback member 50 is fixed. - In order to detach the
back member 50 from thebase member 10, the operation click 72 of the third engagingmember 67 is first operated to move the third engagingmember 67 to a lower position. In this state, thefirst operation member 61 and thesecond operation member 62 are operated to retract the first engagingshaft 53 and the second engagingshaft 54 to a completely retracted position. Since the first engagingshaft 53 and the second engagingshaft 54 are completely retracted from both side walls of theback member 50 into theback member 50, theback member 50 can be detached from thebase member 10. - In the illustrated embodiment, the first engaging
shaft 53 and the second engagingshaft 54 are provided in theback member 50, and thefirst shaft hole 23 and thesecond shaft hole 24 are provided in thebase member 10. In another embodiment, however, the first and second engaging shafts may be provided in the base member and the first and second shaft holes may be provided in the back member. In still another embodiment, the bath chair may have a back member that is detachable from the base member but has a fixed inclination angle. - Although an embodiment of the present invention has been described above with reference to the figures, the present invention is not limited to the illustrated embodiment. Various modifications and variations can be made to the above described and illustrated embodiment within the same scope or an equivalent scope as in the present invention.
- The present invention can thus be advantageously used as a child bath chair that can be kept clean.
