  As shown in FIGS. 1, 3, and 4, the movable portion 30 is inserted into each base member 11 constituting the main body portion 10 and slides back and forth within each base member 11. A pair of left and right movable base members 31 having a length slightly less than twice that of the base member 11 to which the base members 11 are attached, and the support members 15 constituting the main body 10 are inserted into the support members 15. A pair of left and right upper movable members 32 having a length slightly less than twice that of the support member 15 and a connecting member 33 that connects the movable base member 31 and the upper movable member 32 at their rear ends. The handrail member 40 is attached to the upper surface of the upper movable member 32.

  The connecting member 33 has a lower support 34 fixed to the rear end of the movable base member 31 and is inserted into the lower support 34 from the upper end side, and slides up and down in the lower support 34. The upper end is a toilet bowl. The upper strut 35 extends inward in the width direction of A, and the rear end portion of the upper movable member 32 is fixed to the upper end portion of the upper strut 35 that protrudes inward in the width direction of the toilet bowl A.

  Accordingly, each movable base member 31 and the corresponding upper movable member 32 advance and retreat in the front-rear direction, and accordingly, the handrail member 40 attached to the upper movable member 32 is moved. If it slides back, the corresponding movable base member 31 will also move back.

  As shown in FIGS. 1 to 4 and 6, the handrail member 40 includes a metal frame 41 and a resin cover 42 attached to the frame 41. 41 is fixed to a front end portion and an intermediate portion of the upper surface of the upper movable member 32 via a fixing member 43. In addition, a long hole 15 a extending in the front-rear direction is formed on the upper surface of the support member 15 constituting the main body 10, and the rear side of the frame 41 of the handrail member 40 and the intermediate portion of the upper movable member 32 are formed. The fixing member 43 is fixed so as to move back and forth in the long hole 15a.

  As shown in FIGS. 2 and 6A and 6B, the locking means 50 is formed when the slit 51 formed on the lower surface of each support member 15 and the upper movable member 32 are slid back and forth. The three slits 52 formed at equal intervals on the lower surface of the upper movable member 32 that coincide with the slits 51 of the support member 15 and the front of the upper end portion of the upper column 14 projecting inward in the width direction of the toilet A It is configured by a substantially L-shaped lock member 53 having an operation piece 55 continuously provided so as to form an angle of 90 degrees at one end of the rotation piece 54 that is supported. At the tip of the moving piece 54, a locking claw 54 a that can be engaged with the slits 51 and 52 that coincide with each other is provided.

  The lock member 53 is provided with a rotation fulcrum at an intermediate portion on the rotation piece 54 side. In a normal state, the other end side of the rotation piece 54 provided with the operation piece 55 is rotated downward. Then, the locking claw 54 a provided at the tip of the rotating piece 54 is held in a state of entering the slit 51.

  Therefore, when the upper movable member 32 is moved forward and backward, when any one of the slits 52 of the upper movable member 32 coincides with the slit 51 of the support member 15, the locking claw 54 a entering the slit 51 The upper movable member 32 also enters the slit 52, and the upper movable member 32, that is, the handrail member 40 attached to the upper movable member 32 is held in that position. The handrail member 40 can be held at the “advance position”, “intermediate position”, or “retreat position” corresponding to the three slits 52 of the movable member 32, respectively.

  In this way, with the handrail member 40 held in the “advanced position”, “intermediate position” or “retracted position”, the operation piece 55 is moved in the width direction of the toilet bowl A as shown by a two-dot chain line in FIG. When turned inward, the engagement of the locking claw 54a with the slit 52 is released, so that the handrail member 40 can be moved back and forth.

  Further, adjusters 11a and 11a for adjusting the height are attached to the front and rear ends of each base member 11 on the lower surface side, and the toilet floor is inclined in consideration of drainage and the like. Even if it is present, the height can be partially adjusted by the respective adjusters 11a and 11a, so that it is possible to eliminate rattling of the handrail 1 for the toilet bowl installed.

  The toilet handrail 1 configured as described above is used in a state where the handrail member 40 is held at the “advance position” as shown in FIGS. 1 to 4. When an elderly person or the like is transferred from the wheelchair to the toilet A, by operating the operation piece 55 of the right lock member 53, the engagement of the locking claw 54a with the slit 52 is released, and the handrail member 40 is moved backward. When held in the “retracted position”, not only the handrail member 40 but also the corresponding movable base member 31 is positioned on the rear side of the front end of the floor fixing portion a of the toilet bowl A, as shown in FIGS. Therefore, there are no obstacles on the moving route of the elderly and the like so that the elderly can smoothly and reliably transfer from the wheelchair to the toilet A. In addition, when an elderly person etc. transfer to the toilet bowl A, it is not always necessary to retract the handrail member 40 to the “retracted position”, as shown in FIG. 10 and FIG. It is also possible to cause an elderly person or the like to perform a transfer operation to the toilet A with the handrail member 40 held at the “intermediate position”.

  The handrail 1 for the toilet bowl is different from the conventional handrail for the toilet bowl in which the handrail member is flipped backward, and the handrail member 40 held in the “retracted position” when an elderly person or the like changes from the wheelchair to the toilet bowl A. Since the body can be supported by placing a hand on the hand, it is possible to easily transfer to the toilet A as compared with a conventional toilet handrail.

  In addition, because the casters 31a and 31a provided at the front and rear ends of the movable base member 31 are grounded to the floor of the toilet regardless of the holding position of the handrail member 40, when an elderly person transfers from the wheelchair to the toilet A, " Even if the handrail member 40 held at the “retracted position” is put on the hand to support the body, the entire handrail 1 for the toilet bowl is not tilted, and an elderly person or the like can transfer to the toilet bowl A with peace of mind.

  In addition, after the elderly person or the like is seated on the toilet seat, as described above, by operating the operation piece 55 of the lock member 53 directly beside the body, while releasing the engagement of the locking claw 54a with the slit 52, Since the handrail member 40 can be easily advanced, workability is also good.

  In the above-described embodiment, the movable base member 31 constituting the movable portion 30 is inserted into the base member 11 constituting the main body portion 10 and is slid within the base member 11. The pair of left and right movable base members is not limited to this, and may be supported by the main body using various methods so that the left and right sides of the toilet bowl A can be moved forward and backward.

  Further, in the above-described embodiment, the movable base member 31 and the upper movable member 32 are coupled at the respective rear end portions by the coupling member 33, but the present invention is not limited to this, It is also possible to connect at the front end. However, if the movable base member 31 and the upper movable member 32 are connected to each other at their rear ends, the front side of the upright member 12 is released, so the front portion of the movable base member 31 and the front of the upper movable member 32 are released. It can be said that it is a more desirable form because the space between the parts is opened.

  In the above-described embodiment, the locking claw 54a of the lock member 53 enters both the slit 52 of the upper movable member 32 and the slit 51 of the support member 15 to lock the upper movable member 32 in a predetermined position. Although the means 50 is adopted, the present invention is not limited to this, and various locking means that can be held at least in the forward movement position and the backward movement position can be adopted.

  In the above-described embodiment, the movable base member 31 and the upper movable member 32 are connected by the connecting member 33, so that the movable base member 31 and the handrail member 40 are moved forward and backward. However, the present invention is not limited to this. For example, like the handrail 2 for a toilet bowl shown in FIGS. 12 to 14, the movable base member 31 and the upper movable member 32 are individually moved forward and backward. May be.

  In this toilet handrail 2, a grip 36 for advancing / retreating operation is erected at the front end portion of each movable base member 31, and a lock means 60 for locking each movable base member 31 at a forward position is provided. The lock means 60 includes a pipe 61 that is erected so as to surround a fitting hole (not shown) formed in the upper surface of the rear end side of each base member 11, and is movable. A fitting hole 62 formed on the upper surface of the rear end side of the movable base member 31 that matches the fitting hole of the base member 11 when the base member 31 is slid forward, and a lock pin inserted into the pipe 61 63, when the grip 36 is held and the movable base member 31 is advanced, the fitting hole of the base member 11 and the fitting hole 62 of the movable base member 31 coincide with each other. The inserted lock pin 63 enters the fitting hole 62 of the movable base member 31, and the movable base member 31 is held in that position. In order to unlock the movable base member 31, the movable base member 31 may be retracted while the lock pin 63 is lifted and removed from the fitting hole 62 of the movable base member 31.

  Further, in this way, when the movable base member 31 is moved forward and backward independently, it is not always necessary to move the handrail member forward and backward. For example, like the handrail 3 for a toilet shown in FIG. The handrail member 40a may be flipped up backward. Note that the pair of left and right handrail members 40a are locked by a locking means 50a at a predetermined flip-up position that rises substantially vertically.

  The present invention can be used as a handrail for an existing Western-style toilet.
