Description

  The present invention relates to a handrail device for a toilet that assists in sitting, posture (sitting) holding or standing in use of a toilet (particularly, a Western-style toilet) by an elderly person or a disabled person.

  In facilities and homes where elderly people and persons with disabilities live, handrail devices may be provided in the toilets to reduce the burden on those people when using the toilets. Many of such handrail devices are incidental, and are provided separately from the toilet body (toilet bowl) so that the handrails constituting the handrail device are located on the left and right sides of the toilet bowl. A function commonly required for such a handrail device is that the handrail contributes to maintaining posture during use including sitting and standing. For this reason, handrails on the left and right sides of the toilet are used as armrests.

  By the way, when adding work in the toilet, a forward leaning posture in which the elbow or the like is placed on the thigh is taken. However, such an operation is difficult for an elderly person or a handicapped person with weak lower body strength. In view of this, a front handrail for closing the front of the toilet is provided, and in use, the handrail leans on the front handrail to stabilize the posture. This forward handrail should not interfere with access to the toilet, so it must be open when entering and exiting and closed when used.

  There exists a thing of patent document 1 as what provided such a front handrail. In this case, the front handrail is rotated in a horizontal plane so that the front of the toilet is opened and closed. However, when the handrail is extended with the left and right handrails, the presence of the handrail becomes an obstacle. In this state, it is rotated downward in the vertical plane and stored. Therefore, the front handrail has to rotate in a horizontal plane and a vertical plane, and the structure is complicated. In addition, when it is in a horizontal state, it can withstand the load from above, and when it closes the front of the toilet, it needs a lock mechanism that rotates in a horizontal plane so that it does not escape forward, etc. The structure is further complicated.

  The problem to be solved by the present invention is to simplify the movement of the front handrail, thereby reducing the reliability of the movement and the cost with a simple structure.

Under the above-described problems, the present invention provides a handrail device for a toilet in which left and right handrails are supported by struts installed on the left and right sides of a toilet as defined in claim 1, and the front and rear of the struts are disposed on one handrail side. A front handrail that rotates between a standing posture that stands upward with a support shaft provided with its axis oriented in the direction and a use posture that is lowered to a horizontal position and closes the front of the toilet is provided . Locking mechanism that locks this standing posture in addition to the lower handrail facing the toilet bowl when the front handrail is in the upright position when the handrail is in the upper and lower stages of the upper handrail and the lower handrail is provided, the locking mechanism is pivotally secured to the link pin is provided for raising and lowering the guide member supporting shaft side end of the front handrail is沿設the posts, standing posture forward handrail Provided on the release lever by the lowering of the pin when The pin slides down the surface and rotates the release lever toward the release position. When the pin reaches the locking part provided under the slope, the release lever rotates to the lock position by the spring force and returns. At the same time, the handrail device for toilets is provided, wherein the handrail device is characterized in that it is locked to the locking portion and the rise is automatically regulated.

  In this, springs are provided on the upper and lower sides of the pin according to claim 2, when the pin is at the upper part of the lifting range, the pin is bulleted by the upper spring, and when the pin is at the lower part of the lifting range, the pin is at the lower side The front handrail that is springed by the spring of the upper and lower handrails is two steps up and down, and when the front handrail is in an upright position, the lower handrail is facing the toilet side, 4. A means provided with a lock mechanism for holding the standing posture, according to claim 3, wherein a spring is provided above and below the pin, and when the pin is above the lifting range, the pin is repelled by the upper spring, and the pin is lifted When at the bottom of the range, it provides a means by which the pin is springed by the lower spring.

  According to the first aspect of the present invention, since the front handrail only needs to rotate between the standing posture and the use posture, the structure is simplified. Furthermore, since the handrail rotates in the vertical plane and descends from above, the psychological anxiety given to the user compared to the one that rotates in the horizontal plane and approaches from the front. Few. In this case, since the front handrail does not rotate in a horizontal plane, it does not escape forward even if it is not locked in the use posture, and the structure is simple and safe. Of course, this handrail becomes a good grip when in the use posture, and contributes to the stability of the forward leaning posture when adding use. In addition, the lower handrail is most easily gripped when sitting or standing up. At this time, the front handrail is locked by the lock mechanism and does not fall down, so it is safe and separate vertical hand. It is no longer necessary to attach a slide to the wall. Furthermore, since a lock mechanism that automatically holds the standing posture with a simple structure can be obtained, the operation is simple and safe. According to the third aspect of the present invention, the front handrail can be moved with a light force, and the impact when rotating to the standing posture or the use posture is absorbed. According to the means of claim 4, since the other side surface of the toilet bowl is opened, the space is increased and it is easy to go in and out.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIGS. 1 and 2 are perspective views of a handrail device for toilets according to the present invention, FIG. 3 is a front view, and FIG. 4 is a right side view. 5 is a left side view, and FIG. 6 is a plan view. The handrail device includes support columns 2 and 3 installed on the left and right sides of the toilet 1, left and right handrails 4 and 5 provided on the support columns 2 and 3, and a front handrail 6 that opens and closes the front of the toilet 1. .

  Of these, one (right or left) support column 2 includes a grounding portion 2a provided with a screw mounting structure and the like and fixed on the floor, a standing portion 2b standing from the front end of the grounding portion 2a, and a standing portion. The horizontal portion 2c extends horizontally from the front end of 2b toward the rear, and the oblique side portion 2d extends obliquely rearward and upward from the rear end of the horizontal portion 2c. In this, the horizontal part 2c constitutes one handrail 4, and an elbow rest part 7 made of wood or resin is provided on the upper surface. Therefore, one handrail 4 is fixed.

  The other support column 3 also has a grounding portion 3a, an upright portion 3b, and a hypotenuse portion 3d (no horizontal portion is provided), but the upright portion 3b stands up from the rear end of the grounding portion 3a. The oblique side 3d extends obliquely forward and upward from the upper end of the upright portion 3b. The upper ends of both the oblique sides 2d and 3d are located on the left and right concentric sides and are connected by the bridging portion 8.

  A horizontal support shaft 9 projects from the outer surface of the other hypotenuse 3d, and the other handrail 5 is rotatably fitted by a boss 5a formed at the rear end thereof. As a result, the handrail 5 is provided so as to be rotatable between an open posture in which the side of the toilet 1 is opened and the toilet 1 is stood diagonally rearward and a use posture that is lowered horizontally. For this reason, although not shown, a stopper mechanism is provided between the boss 5a and the support shaft 9 so that only rotation within this range is possible.

  In this case, the grounding portion 3a extends obliquely rearward of the toilet 1 and the upright portion 3b stands from the rear end thereof. When the handrail 5 is in the open posture, the side of the toilet 1 is completely opened. ing. In addition, the front end of the grounding portion 3a starts from the middle of the toilet 1 so as not to obstruct the feet when entering and exiting. In addition, this handrail 5 takes the same form as the horizontal part 2c of one handrail 4 when it is in a use posture, and an elbow rest part 10 made of wood or resin is provided on the upper surface thereof. In addition, a backrest 11 is appropriately provided in the bridging portion 8.

  A support shaft 12 protrudes horizontally at the upper part of the front surface of the upright portion 2b of one of the columns 2, and spans between a standing posture in which the front handrail 6 stands upward with respect to the support shaft 12 and a use posture in which the handrail 6 falls horizontally. It is provided so that it can rotate. In the front handrail 6 of this example, the upper handrail 6b extends from a boss 6a that is rotatably fitted to the support shaft 12, and the lower handrail 6c is suspended from the lower surface of the upper handrail 6b. It is fixed and extends like a trombone in two upper and lower stages, and an elbow rest 25 made of wood or resin is provided on the upper surface of the upper handrail 6b.

  In this case, when the front handrail 6 takes the standing posture or the use posture, it interferes with the elbow rest portion 7 of one handrail 4 or the elbow rest portion 10 of the other handrail 5 when the handrail is taken. In addition, it is not preferable that it is unnecessarily long. For this reason, the front end of one of the elbow rests 7 is slightly retracted, and the front end of the other elbow rest 10 is advanced over the extension of the elbow rest 25 of the front handrail 6 (when in a use posture). A slight gap is secured between the two. In short, when the front handrail 6 and the other handrail 5 are in the use posture, the inner hand space 4 and the bridge portion 8 (backrest 11) surround the inner space. This is to ensure safety so that the user's body does not fall.

  The upper handrail 6b is provided with an end portion 6d protruding outward from the upper side of the boss 6a. A link 14 is pivotally attached to the end portion 6d by a pin 13, and the link 14 is connected to the standing portion 2b. It hangs down along the front surface of the guide member 15 provided along. 7 is a front view of the main part showing the relationship between the link 14 and the guide member 15, FIG. 8 is a side view of the main part, and FIG. 9 is a front view of the main part. 16 protrudes and this pin 16 protrudes into the long hole 23 formed in the guide member 15 up and down.

  A release lever 18 is provided on the front surface of the guide member 15 (the rear surface of the link 14). The release lever 18 can be turned left and right around a mounting shaft 17 provided at the lower portion thereof. A slope portion 19 whose slope gradually increases is formed, and a substantially horizontal locking portion 20 is formed immediately below the slope portion 19. In addition, springs 21 and 22 are respectively provided above and below the pin 16 in the guide member 15 so that the pin 16 can be repelled.

  With the above configuration, when the front handrail 6 is in the upright position, as shown in FIG. 9, the pin 16 is locked to the locking portion 20 and does not rise, but is held in this position (front handrail). 6 does not descend). Therefore, when the locking portion 20 is removed from the pin 16 at the release position where the release lever 18 is pushed outward, the pin 16 can be lifted freely, so that the front handrail 6 can be in a use posture. At this time, since the pin 16 can be automatically raised by the lower spring 22 in the compressed state, the pin 16 can be moved forward only by operating the release lever 18 (without performing the operation of tilting the front handrail 6). The handrail 6 can be moved to the use posture.

  Furthermore, since the upper spring 21 is compressed as the pin 16 is raised, the front handrail 6 is gently lowered against its own weight, which is safe. When the front handrail 6 is in the use posture, the user can lean on this, and the load is received by the support shaft 12 via the boss 6a, so that the load (weight) can be supported. In this case, since it is necessary to prevent the front handrail 6 from rotating downward from the use posture, the illustration is omitted, but in this example, the front handrail 6 is not provided between the boss 6a and the support shaft 12 below. A stopper mechanism is provided to prevent rotation.

  Next, when the front handrail 6 is changed from the use posture to the standing posture, the pin 16 is guided by the long hole 23 and gradually descends and slides down the slope portion 19 of the release lever 18, and the release lever 18 is released by the reaction. It is pushed out to the release position side (state shown in FIG. 10), and finally locked under the locking portion 20 (state shown in FIG. 9). At this time, the release lever 18 is rotated and returned to the lock position immediately when the pin 16 reaches the position of the locking portion 20.

  Specifically, a light torque spring 24 is incorporated between the guide member 15 and the release lever 18. In this respect, the members such as the pin 16, the release lever 18 and the torque spring 24 constitute a lock mechanism that automatically holds the standing posture of the front handrail 6. Although not shown in the drawings, a stopper mechanism is provided between the boss 6a and the support shaft 12 so as to prevent further rotation when the front handrail 6 is in the standing posture.

  As described above, when the front handrail 4 is set in the standing posture, the posture is firmly held. In this posture, the lower handrail 6c stands up slightly outward from the upright portion 2a, and this is a good gripping body. In particular, the elderly and the handicapped require the most power when sitting on the toilet 1 or standing up. The presence of such a strong handrail 6c as a vertical handrail is a great assistance. It is encouraging. Since the springs 12 and 22 are provided above and below the pin 16, these balance the force required to move the pin 16 up and down (the raising and lowering of the front handrail 6). It can be moved safely, and the buffering action when the front handrail 6 is moved to the standing posture or the use posture is also exhibited.
