Description

  The present invention relates to a handrail device in a toilet room or a bathroom, and more particularly to a handrail device useful for sitting or standing on a toilet seat in a toilet room or for sitting or standing in a bathroom.

  It is well known that a user with weak legs, such as the elderly, installs a handrail in the toilet room in order to sit and stand on the toilet seat with support from the hand, and recently, the user is seated on the toilet seat. The handrail is locked in a position that crosses the front upper side of the toilet, and when the user tries to sit on the toilet seat or stands up and away from the toilet seat, the handrail is in a position that does not interfere with it. Examples of movement (see, for example, Patent Document 1) are also seen.

  When the user is seated on the toilet seat, the handrail device that is locked at a position where the handrail crosses over the front upper side of the toilet bowl is compared to the handrail device that is located on the side of the toilet bowl in the front-rear direction. In particular, since the user at the sitting position can hold the handrail with both hands or lean against the handrail, the user's posture at the sitting position is stabilized, so that the user falls from the sitting position. This is useful because accidents can be prevented considerably and the caregiver can easily perform work such as undressing. However, such a handrail device has many parts and is difficult to install at low cost. In addition, the handrail is not fully used when entering or leaving the room, or the handrail in the vertical direction and the handrail in the horizontal direction are selectively used or replaced. To change the direction of the wrist, the operation cannot be performed unconsciously, or when the movable handrail is raised or lowered, the hand that rotates the movable handrail and the fixed handrail As a result, the hand supporting the body is entangled with each other, and there is a possibility that the user cannot fall unless the hand is released from the fixed handrail. Also, handrails cannot be used when entering or leaving the toilet room. Therefore, there remains room for improvement in these respects. The same can be said for the sitting area in the bathroom.

The handrail support 1 is fixed on the wall surface W by being positioned on the wall surface W so that the handrail basket 2 is disposed at an appropriate position across the upper front side of the toilet T. 2 shows the handrail device in a state where the handrail basket 2 crosses the toilet bowl T, and FIG. 3 shows the handrail device in a state where the handrail basket 2 is along the wall surface W. In the present invention, the locking device that is detachably locked at the position where the handrail basket 2 crosses the front upper side of the toilet bowl T and the position along the wall surface W in front of the wall surface W is not particularly limited. However, an embodiment including such a locking device will be described below.

  In the handrail device, the handrail support 1 is formed in a short cross-sectional U shape as shown in FIGS. That is, the upper plate portion 5 having the hand-mounted surface portion 4 attached to the upper surface is attached to the upper edge of the side plate portion 3 fixed to the wall surface W along the front-rear direction of the toilet bowl T, and the lower plate portion is attached to the lower edge of the side plate portion 3. 6 are formed so as to protrude opposite to each other. Although the main part of the handrail support 1 is made of a hard material such as metal, the hand-mounted surface part 4 to be attached to the upper surface is a fiber-reinforced synthetic resin that is easy to touch because the user's hand is placed. And the corners are chamfered. Also, as shown in FIGS. 4 to 7, in this embodiment, the lower plate portion 6 is also provided with a fiber-reinforced synthetic resin layer 7 applied to the upper surface thereof, which helps to improve workability. . As shown in FIGS. 6 and 7, the side plate portion 3 of the handrail support 1 is fixed to the wall surface W by fixing screws 8 and 8. As shown in FIGS. 4 and 5, between the upper plate portion 5 and the lower plate portion 6 of the handrail support 1, a support shaft 9 with a handrail rod 2 attached to the vicinity of the center is provided from above and below the upper plate. The screws 10 and 10 are erected by screwing the screws 10 and 10 into the support screw holes 11 and 11 of the support shaft 9 through the part 5 and the lower plate part 6. Since the screw head of the screw 10 screwed through the upper surface plate 6 is accommodated in the hand-mounted surface portion 4, it is not exposed on the upper surface of the hand-mounted surface portion 4 and the touch is not deteriorated.

  6 and 7, a toilet room in which a lower part 19 (to be described later) of the handrail rod 2 can be fitted on the lower plate part 6 of the handrail support 1 around the support shaft 9. The front and rear grooves 12 extending in the direction along the wall surface W and the left and right grooves 13 extending in the direction perpendicular to the wall surface W of the toilet room are recessed, and the front and rear grooves 12 and left and right grooves on the wall surface W side of the toilet room are also provided. 13, recessed screw holes 14 and 14 are provided for screwing a protruding screw leg portion 27 b of a stop protrusion 27 described later. In order to allow the handrail device to be installed on any of the left and right wall surfaces W of the toilet room, the concave screw holes 14 are formed with left and right concave grooves 13 in the front-rear direction of the lower plate portion 6 of the handrail support 1. The center is symmetrically recessed at two locations, and only one location is selected according to the wall surface W to be installed, and the projecting screw leg portion 27b of the stop projection 27 is screwed. Furthermore, in this embodiment, a concave arcuate flat surface 15 is formed around the support shaft 9 for the tip portion 30 of the splaying member 29 accommodated in the handrail rod 2 to be described later to press contact. . These front and rear concave grooves 12, left and right concave grooves 13, concave screw holes 14 and 14, concave arcuate flat surface 15 and the like are all formed on a fiber-reinforced synthetic resin layer 7 attached to the upper surface of the lower plate portion 6 that can be easily processed. The

  Next, the handrail 2 will be described. As shown in FIG. 8, the handrail rod 2 has a handrail skeleton 17 made of a rigid material such as a metal having a mouth-shaped cross section with horizontal flanges 16, 16 protruding on both upper edges. A soft handrail coating layer 18 made of a soft synthetic resin such as urethane foam and having an inverted C-shaped cross section has a cross-sectional structure in which the upper part of the handrail skeleton 17 is covered so as to wrap the horizontal flanges 16 and 16. A characteristic point in the cross section of the handrail 2 is that the lower portion 19 of the handrail 2 has a box-shaped cross section in which both vertical surfaces 21 and 21 rise from both sides of the bottom surface 20. The handrail rod 2 extends from the support side end 22 on the side where the handrail is supported by the handrail support 1 to the grip side end 23 on the side gripped by the user. Part caps 24, 24 are fitted. The horizontal handrail rod 2 is pivotally attached to the support shaft 9 at a location close to the support side end 22 so as to be horizontally rotatable and vertically movable. That is, a block 25 is built and fixed in the vicinity of the support-side end 22 of the handrail 2, and a bearing 26 is attached to the block 25 so that the handrail 2 can be horizontally rotated and moved up and down. Then, by inserting the bearing 26 into the support shaft 9, the handrail rod 2 is attached to the support shaft 9.

  The handrail rod 2 can be horizontally rotated around the support shaft 9 and can be moved up and down. The handrail rod 2 is horizontally rotated with the handrail rod 2 lifted, and the front and rear concave grooves 12 in the lower plate portion 6 of the handrail support 1 are formed. When the handrail basket 2 is lowered at the position, that is, the position along the wall surface W of the toilet room, the lower portion 19 of the handrail basket 2 is fitted and locked in the front and rear concave grooves 12 of the lower plate section 6. Is done. Similarly, if the handrail basket 2 is lowered at the position of the left and right concave grooves 13 in the lower plate portion 6 of the handrail support tool 1, that is, the position where the handrail basket 2 crosses the front upper side of the toilet T perpendicular to the wall surface W, The lower part 19 of 2 is fitted and locked in the left and right concave grooves 13 of the lower plate part 6. Thus, since the cross-sectional shape of the handrail rod 2 itself constitutes a part of the latching means of the handrail rod 2, the failure of the latching means can be generated by simplifying the structure of the latching means. Can be prevented as much as possible, and the number of parts can be reduced, and manufacturing can be made at low cost. Further, since the horizontal rotation operation of the handrail rod 2 and the vertical movement operation at the position of the front and rear concave grooves 12 and the left and right concave grooves 13 are performed only by the operation of the handrail rod 2, the operation is simple and does not burden the user. Since a separate operation means is not required, the number of parts can be reduced and manufacturing can be performed at low cost. 2, 6, 7, and 9, the stop protrusion 27 is a protrusion head whose outer periphery that is in contact with the vertical surface 21 of the handrail 2 is covered with a synthetic resin layer so that it can be replaced in this embodiment. 27a and a separate part provided with a protruding screw leg part 27b for screwing into the concave screw hole 14 of the lower plate part 6 are formed by screwing. As described above, the concave screw holes 14 are recessed in the lower plate portion 6 at two locations, but only one stop protrusion 27 is required when the handrail 2 is rotated to a position along the wall surface W. The grip-side end 23 of the handrail 2 is formed by screwing a component only into one concave screw hole 14 on the side facing the front of the wall surface W.

  As shown in FIG. 7, when the lower part 19 of the handrail 2 is fitted in the front and rear concave grooves 12 at a position along the wall W in front of the wall W, the grip 9 is closer to the grip side end (support). Even when the vertical surface 21 of the handrail 2 near the side end 22 abuts against the stop protrusion 27 and lifts the handrail 2, the handrail 2 is further horizontally rotated so that the handrail 2 becomes a wall surface. Prevent access to W. Similarly, as shown in FIG. 6, when the lower portion 19 of the handrail basket 2 is fitted into the left and right concave grooves 13 at a position where the handrail basket 2 crosses the upper front side of the toilet bowl T, it is closer to the support side end 22 than the support shaft 9. Even when the vertical surface 21 of the handrail basket 2 comes into contact with the stop protrusion 27 and lifts the handrail basket 2, the handrail basket 2 is further rotated horizontally to approach the user side seated on the toilet T. To prevent. Thus, the stop projection 27 not only guides the positions of the front and rear concave grooves 12 and the left and right concave grooves 13 to be fitted when the handrail 2 is rotated, but also excessively rotates the handrail 2. To prevent. Although it is possible to project the stop projection 27 fixed from the beginning on the lower plate portion 6, if the stop projection 27 is formed as a separate part, it can be replaced when worn out. Even when 1 is installed on either the left or right wall surface W of the toilet T, the stop projection 27 is formed by screwing a part into one of the recessed screw holes 14 provided in the lower plate portion 6 at two locations. The handrail support 1 having the same structure can be used.

  As shown in FIGS. 4 to 7, a vertical hole 28 is drilled at a location close to the support shaft 9 in the direction of the gripping side end 23 of the block 25 built in and fixed to the handrail 2, and is formed downward in the interior. A striking member 29 that biases toward the housing is accommodated. And the front-end | tip part 30 of the rolling member 29 in the handrail rod 2 pivotally attached to the handrail support tool 1 contacts and presses the recessed arcuate flat surface 15 of the lower plate part 6 in the handrail support tool 1 described above. This pressing generates a reaction force that lifts the handrail 2. By applying the adjusted elasticity to the splaying member 29 against the gravity of the handrail 2, the lower portion 19 of the handrail 2 is moved into the front and rear concave grooves 12 or the left and right concave grooves 13 when the hand is released from the handrail 2. In addition to being securely fitted, when the handrail 2 is lifted from these fitted states, it can be lifted with a slight force, so even a weak user can easily operate the handrail 2. be able to.

  Next, a method for using the handrail device of the present invention will be described. In the handrail device of the present invention, the object to be grasped or placed by the user's hand is both the handrail 2 and the hand-mounted surface portion 4 on the handrail support 1. 10 to 14 show typical examples in which the handrail device is used. As shown in FIG. 10, the user who has entered the toilet room through the door D moves forward by holding the handrail 2 at a position along the wall surface W with one hand immediately after entering the room. Next, as shown in FIG. 11, the other hand is placed on the hand-mounted surface portion 4 on the handrail support 1 while rotating the body, and the weight of the toilet surface T is borne by the hand-mounted surface portion 4. Sit on the toilet seat. Further, as shown in FIG. 12, the handrail 2 at a position along the wall surface W is lifted with one hand, and the handrail rod 2 at the position along the wall surface W is unlocked and then pulled toward the user side. The handrail basket 2 is lowered at a position crossing the upper front of the toilet bowl T, and the handrail basket 2 is locked at this position. Then, as shown in FIG. 13, the body is supported by, for example, placing both hands and arms on the handrail 2 while sitting on the toilet seat after adjusting the seating position.

  When leaving the toilet room from the state of being seated on the toilet seat, the other hand is placed on the hand-mounted surface portion 4 while being seated on the toilet seat so as to return to the state shown in FIG. After lifting the bag 2 and releasing the lock at the position crossing the front upper part of the toilet bowl T, the bag 2 is rotated forward and lowered at a position along the wall surface W to lock the handrail bag 2. Then, stand up with the weight placed on the other hand placed on the hand-mounted surface portion 4, move the other hand from the hand-mounted surface portion 4 to the continuous handrail 2, and move forward. Leave the toilet room. As described above, in a typical use example, at least one hand of the user grasps or places either the handrail 2 or the hand-mounted surface portion 4 of the handrail support 1 in the toilet room, and the body Can be supported, and a situation in which both hands must be released does not occur, so that the user can be prevented from falling. In addition, when entering and leaving the toilet room, the handrail 2 is locked at a position along the wall surface W, so that it is possible to walk using the handrail 2.

  In the present invention, the hand-mounted surface portion 4 existing on the upper part of the handrail support 1 is used as a means for supporting the user's body, thereby reducing the total number of parts of the handrail device at low cost. Can do. Further, as is clear from the above-mentioned use example, when the user must sit on the toilet seat or stand up from the toilet seat which must support the maximum body load, Since a hand is placed on the hand-mounted surface portion 4 of the handrail support tool 1 that is not used, the weight can be stored with certainty, so that the sitting operation and the standing operation can be performed stably. Since the handrail surface 2 and the hand-mounted surface portion 4 of the handrail support tool 1 are substantially the same height, both hands are used between the handrail surface 2 and the hand-mounted surface portion 4 of the handrail support device 1. The movement from the grip or placement of one hand to the grip or placement of the other hand, and the movement between the handrail basket 2 and the hand rest surface portion 4 in the handrail support 1 when using one hand are substantially Since the operation is performed in the horizontal direction, the operation is easy and safe, and there is little mental burden. At the same time, the direction of the wrist that grips the handrail rod 2 and the direction of the wrist placed on the hand-mounted surface portion 4 of the handrail support tool 1 are the same direction, and the user can perform all operations without changing the direction of the wrist. In this respect, the operation is easy and safe, and the mental burden is small.

  Next, a modified example of the hand-mounted surface portion 4 in the handrail support 1 will be described.
