Description

  The present invention relates to an armrest device for a toilet (toilet bowl) provided with a toilet seat, and relates to an armrest device for a toilet that assists a user to hold, stand up, and sit on a toilet seat.

  When an elderly person or a handicapped person uses a toilet seat with a toilet seat (hereinafter referred to as a toilet), the handrail provided in the room is handed over to the armrest provided in the toilet. Sit on the toilet seat by using your body to sway. The armrest is also used when the user stands up from the toilet seat and supports the body on the toilet seat.

  As described in Patent Document 1, the conventional armrest device for a toilet has side frames standing substantially vertically on a pair of horizontal tubs on both the left and right sides of the toilet, and the pair of left and right side frames. A handrail (armrest) extending in the front-rear direction is provided at the upper end of each. Since this conventional armrest device for toilets is placed on both sides of the user after the user is seated on the toilet seat, there is a problem that the armrest becomes an obstacle during the sitting operation. The armrest device for a toilet described in Patent Document 1 includes a lower armrest portion whose handrail is fixed to a side frame and an upper armrest portion that slides in the front-rear direction with respect to the lower armrest portion. Thus, the position of the upper armrest portion can be adjusted slightly in the front-rear direction.

  Moreover, the handrail for toilet bowl described in Patent Document 2 is provided with standing members standing substantially vertically on a pair of base members on both left and right sides of the toilet bowl, and at the upper ends of the left and right pair of standing members. A handrail member extending in the front-rear direction is provided. The handrail member has a tip end portion that can be flipped up rearward. Since the handrail member described in Patent Document 2 has a grip extending downward on the lower surface of the handrail member, the grip appears horizontally when the handrail member is flipped up backward. It has become. For this reason, when the user moves up to the toilet seat, if the handrail member is flipped up, this grip becomes an armrest instead of the handrail member, and for example, the body is transferred from the wheelchair to the toilet seat while using this grip. be able to. After the transfer, if the handrail member is brought down to the original state, the body can be stabilized as the armrest after the handrail member is seated on the toilet seat.

FIG. 5 and FIG. 5 are perspective views showing a toilet (toilet) in which the armrest device for toilet of the present embodiment is installed. As shown in FIG. 5, on the left and right sides of the toilet seat 2 of the toilet 1 installed in the rest room, the toilet seat 2 of the armrest 3 is placed on a floor of the rest room, and a pair of supports arranged in parallel to each other. The eaves 4a and 4b are placed with their longitudinal directions parallel to the floor or the like. Support rods 5 a and 5 b are erected on the support rods 4 a and 4 b, and the support rods 5 a and 5 b are fixed to the toilet 1 by a fixing member 10. The support bars 5a and 5b have a hollow bar shape, and the upper and lower bars 6a and 6b are inserted into the support bars 5a and 5b. And the position of the upper and lower bars 6a and 6b can be adjusted by adjusting the insertion position of the upper and lower bars 6a and 6b into the support bars 5a and 5b. In addition, armrests 7a and 7b extending slightly curved in the horizontal direction are fixed to the upper ends of the upper and lower bars 6a and 6b.

  As shown in FIGS. 1, 2 and 3, the fixing member 10 has a frame 11 having a U shape in a plan view, with the bottom portion of the U shape facing forward, and the portions on both sides of the U shape are The support rods 5a and 5b are arranged so as to face each other. The front portion of the frame 11 is provided with two front contact portions 12 bent at an appropriate angle so that the ceramic toilet 1 is not damaged. The surface of the frame 11 is covered with a rubber plate or the like. A mounting portion 13 is provided on the side of the frame 11, and the frame 11 is fixed to the support rods 6a and 6b by fixing the mounting portion 13 to the pair of support rods 6a and 6b by welding or the like. Has been. Thus, the support bars 5a and 5b are arranged in parallel by the frame 11 at appropriate intervals. Further, a pressing rod 14 that is screwed into the frame 11 and can be retracted from the frame 11 toward the toilet 1 by rotation thereof is provided at the open end of the frame 11. The tip of the pressing rod 14 is also covered with rubber or the like so that the toilet 1 is not damaged when the tip of the pressing rod 14 comes into contact with the toilet 1. With the fixing member 10 configured in this manner, with the front contact portion 12 in contact with the front portion of the toilet 1, the push bar 14 is advanced toward the toilet 1, so that the front end portion of the fixing member 10 is moved to the toilet 1. The frame 11 is fixed to the toilet 1 by making the contact and pressing the toilet 1 with the pressing bar 14. The frame 11 can be detached from the toilet 1 by retracting the pressing bar 14 (separating from the toilet 1).

  The armrests 7a and 7b are slightly curved and basically extend in the front-rear direction, and support portions 8a and 8b are provided at positions biased toward one end thereof. The support portions 8a and 8b are fixed to the upper ends of the upper and lower bars 6a and 6b. Thereby, the armrests 7a and 7b are supported by the vertical upper and lower bars 6a and 6b so as to be in a horizontal posture via the support portions 8a and 8b.

  The support bar 5 (5a, 5b) and the upper and lower bars 6 (6a, 6b) are both close to an elliptical shape with a hollow cross section, the horizontally long part is flat, and both ends of the flat part are semicircular parts, It has a shape that connects the front and back flat parts. The cross section of the upper and lower bars 6 and the support bar 5 is slightly larger than that of the upper and lower bars 6 so that the upper and lower bars 6 can be inserted into the support bar 5. A nut 21 is fixed to the upper portion of the support bar 5 so that its axial direction is horizontal and perpendicular to the surface of the support bar 5, and the screw bar 22 is screwed onto the nut 21 so that the handle 22a is engaged. By grasping and rotating the screw rod 22 forward and backward, the screw rod 22 can advance into the support rod 5 or be separated from the support rod 5. The upper and lower bars 6 inserted into the support bar 5 are formed so that a plurality of holes 23 are scattered in one row along the longitudinal direction of the upper and lower bars 6 in flat portions on both sides of the front and back. Yes. As clearly shown in FIG. 7, the row of the holes 23 is arranged at a position deviated to one side from the center line of the wide portion of the upper and lower bars 6. Similarly, the nut 21 of the support bar 5 is also biased to the one side with the same degree of bias, and when the screw bar 22 advances into the support bar 5, the upper and lower bars 6 inserted into the support bar 5. As shown in FIG. 7 (b), it is in contact with the inner surface of the upper and lower bar 6. By adjusting the screwing amount of the screw rod 22, the screw rod 22 presses the inner surface of the upper and lower rods 6 and presses the surface facing the hole 23 of the upper and lower rods 6 toward the inner surface of the support rod 5. Thereby, the upper and lower bars 6 are fixed to the support bar 5.

  A plurality of other holes 24 are formed in the flat portion on the back side of the upper and lower bars 6 in a row in parallel with the longitudinal direction of the upper and lower bars 6. As shown in FIG. 7B, these holes 23 and 24 are provided at point-symmetrical positions around the center line of the upper and lower bars 6 in plan view. Therefore, when the upper and lower bars 6 are turned over and inserted into the support bar 5, the hole 24 is aligned with the position of the nut 21.

  Next, operation | movement of the armrest apparatus for toilets comprised in this way is demonstrated. First, as shown in FIGS. 1 and 4, the lower half of the armrest device including the support rods 4 a, 4 b, the support bars 5 a, 5 b, and the frame 11 is arranged around the toilet 1, and the front contact portion of the frame 11 12 is brought into contact with the toilet 1, the pressing rod 14 is pushed in, and the toilet 1 is pressed at the tip thereof. As a result, the lower half of the armrest device is fixed to the toilet 1.

  Thereafter, as shown in FIG. 4, the upper and lower bars 6a and 6b fixed to the armrests 7a and 7b are inserted into the support bars 5a and 5b. At this time, the armrest 7a and the upper / lower bar 6a arranged on the right side of the toilet 1 insert the upper / lower bar 6a into the support bar 5a so that the armrest 7a faces a normal direction. The normal direction of the armrest 7a is a direction in which the direction extending longer than the support portion 8a faces forward. At this time, the armrest 7a operates sufficiently for its original function of gripping with a hand or putting the elbow on the body. As shown in FIG. 4, the armrest 7b and the upper and lower bar 8b arranged on the left side of the toilet 1 are also shown in FIG. 3 when the upper and lower bar 6b is inserted into the support bar 5b so that the armrest 7b faces the normal direction. Thus, both armrests 7a and 7b face normal directions, and both armrests 7a and 7b extend longer forward than the toilet 1. For this reason, in this aspect, after the user wears on the toilet seat, it functions to hold any armrest 7a, 7b or to put the elbow on the body, so in a preferred aspect It can be said that there is. However, when the user moves, for example, when entering the toilet seat 2 of the toilet 1 from the left side of the toilet 1, the left armrest 7b obstructs the transfer.

  Therefore, when the rest room is arranged as described above and the user enters the toilet seat 2 from the left side of the toilet 1, the armrest 7b is used as shown in FIG. The upper and lower bars 6b are inserted into the support bar 5b so that the part extending longer than the support part 8b faces the back of the toilet 1, that is, the short part of the armrest 7b faces the front of the toilet 1. At this time, the upper and lower bars 6b are reversed in the case of FIG. 4, but the hole 24 is opposed to the nut 21 of the support bar 5b because the hole 24 is formed at a point-symmetrical position of the hole 23. For this reason, when the handle 22a is gripped, the screw rod 22 is screwed onto the nut 21 and the screw rod 22 is screwed, the screw rod 22 passes through the hole 24 and faces the hole 24 of the upper and lower rods 6b. Press the inner surface. Thereby, since the screw rod 22 presses the upper and lower rods 6b toward the support rod 5b, the upper and lower rods 6b are fixed to the support rod 5b. The height of the armrests 7a and 7b can be adjusted by appropriately selecting the holes 23 and 24 through which the screw rods 22 are inserted.

  In this aspect, as shown in FIG. 1, since the left armrest 7b faces rearward, the front of the armrest 7b is shorter than the support bar 5b and the upper and lower bars 6b. For this reason, the user can transfer to the toilet seat 2 easily and smoothly. After sitting, the user can touch the body using the right armrest 7a that extends long forward. In addition, as shown in FIG. 2, when facing the normal direction (the direction in which the long extending portion faces forward) as in the right armrest 7a, and in the reverse direction (forward) as in the left armrest 7b. The length extending forward from the toilet 1 is different by X in the case of facing the case where the portion extending in the direction is short. As shown in FIG. 1 and the like, the length of X varies depending on the degree of deviation of the position where the armrests 7a and 7b are attached to the upper and lower bars 6a and 6b. Is possible. Therefore, in the embodiment of FIG. 1, a space of about 190 mm can be opened on the left side of the toilet 1.

  In this way, the bed installer can change the armrest device to either the right armrest 7a or the left armrest 7b according to the arrangement of the toilet 1 in the restroom and the flow line of the user, The upper and lower bars 6 may be inserted into the support bar 5 so as to face rearward, and the upper and lower bars 6 may be fixed to the support bar 5 by the screw bars 22. In this embodiment, even if the upper and lower rods 6 are inserted into the support rod 7 so that the portions extending from the upper and lower rods 6 of the armrests 7a and 7b face forward, the portions extending forward from the upper and lower rods 6 are not. Even if it is inserted into the support rod 7 so as to be short, the holes 23 and 24 are formed at point-symmetrical positions with respect to the center line of the upper and lower rods 6. The upper and lower bars 6 can be fixed to the support bar 5. For this reason, the armrest device of the present embodiment is extremely versatile. And according to this embodiment, while making one armrest function in order to support a body, the other armrest can be made not to become obstructive at the time of a user's transfer, and a user's sitting position maintenance, standing up Easy to sit and move.

  Next, a second embodiment of the present invention will be described with reference to FIGS. 8 (a) and 8 (b). Inserting the upper and lower bars 6 into the support bar 7 is the same as in the first embodiment shown in FIG. 1 and the like, but a nut 21 is provided at the center of the support bar 7, and a screw bar 22 is attached to the nut 21. It is designed to be screwed together. The upper and lower rods 6 are formed with recesses 29, and the upper and lower rods 6 are fixed to the support rods 5 by screwing the screw rods 22 and pressing the tips of the screw rods 22 against the recesses 29 of the upper and lower rods 6. It is supposed to be. Since the concave portion 29 is formed on both the front and back flat portions of the upper and lower rods 6, even if the armrest is turned over and the upper and lower rods 6 are inserted into the support rod 5, the upper and lower rods 6 are supported by screwing of the screw rods. It can be fixed to the bar 5. Therefore, the second embodiment also has the same effect as the first embodiment.

  FIG. 9 is a diagram showing a third embodiment of the present invention. In the present embodiment, a flange 32 is provided on the upper end portion of the support bar 7 for tightening the upper end portion to reduce its inner diameter. The flange 32 can be tightened with a bolt 31 and a nut 33 to shorten the interval between the flanges 32 and tighten the upper end portion of the support bar 7. Thereby, after inserting the upper and lower bar 6 into the support bar 5, the upper and lower bar 6 can be fixed to the support bar 5 by tightening the bolt 31 and the nut 33.

  FIG. 10 is a diagram showing a first embodiment of the second invention of the present application. A support column 40 is erected on a support rod (see support rods 4a and 4b in FIG. 1) placed on the floor in the rest room, and a rotating shaft 42 extending in the horizontal direction is provided at the upper end of the column 40. It is provided so as to be rotatable with respect to 40. An armrest 41 is fixed to the rotating shaft 42, and the armrest 41 can rotate about the horizontal axis with respect to the support column 40 via the rotating shaft 42. And the auxiliary rest 43 is being fixed to the upper end part of this support | pillar 40 with a horizontal attitude | position. The armrest 41 is configured to overlap the auxiliary rest 43 when in a horizontal posture. In addition, on the lower surface of the armrest 41, an operation lever 44 is disposed on the distal end side, and a lock fitting 45 is disposed on the proximal end side. On the other hand, a lock fitting receiver 46 is provided on the distal end surface of the auxiliary rest 43. 10 (b) and 10 (c), the lower end of the lock fitting 45 is bent in a key shape. As shown in FIG. 10 (b), the lock-like portion at the bottom of the lock fitting 45 is provided. Is engaged with the lock fitting receiver 46 of the auxiliary rest 43, and a position where the lower key-shaped portion of the lock fitting 45 is detached from the lock fitting receiver 46 as shown in FIG. .
