Description

  The present invention relates to a telescopic handrail device, and more particularly to a telescopic handrail device that is disposed in a bathroom or the like and assists a bathing operation of an elderly person or a physically handicapped person.

  2. Description of the Related Art Conventionally, a handrail device used in a bathroom is known in which a handrail (grip bar) is erected in a vertical direction from an installation surface such as a counter or a floor (for example, Patent Document 1). This handrail is set to a thickness suitable for a bather to hold, and is able to support the body when sitting down or standing up at a washing place.

  However, when a healthy person takes a bath and takes a shower in a standing state, there is a problem that the handrail gets in the way or the bathroom feels narrow due to the presence of the handrail. Therefore, recently, a structure in which a handrail erected from the counter can be stored in the counter, in other words, the handrail is supported to be slidable in the vertical direction with respect to the counter, and the use position and the storage position are defined. Have been proposed, that is, the entire length can be expanded and contracted.

  In addition, when such an expansion-contraction structure is employ | adopted, it is necessary to provide the lock mechanism which controls sliding of a handrail, and the lock release mechanism which cancels | releases the lock state of the lock mechanism. That is, it is necessary to slide the handrail to a desired height with the lock released, and then fix the handrail by the lock mechanism.

JP 2002-17599

  However, since a relatively large force for supporting the body is applied to the handrail in the use position, a strong and large mechanism is generally used in the lock mechanism, and this increases the overall size. At the same time, the manufacturing cost will increase significantly.

  Further, in the handrail device as described above, it is desirable to change the expansion and contraction state of the handrail relatively frequently according to the bather. However, when a complicated lock mechanism is used, the release operation becomes complicated and easy. Cannot be released. That is, forcing a complicated operation makes the adjustment work troublesome, and there is a possibility that the convenience of the slidable configuration may not be utilized.

  Furthermore, if the user forgets to lock the lock mechanism, the user may suddenly fall from the use position to the storage position during use, and the bather's safety cannot be ensured.

  Therefore, in view of the above situation, the present invention can reduce the size and cost of the lock mechanism, and can easily release the locked state, and reliably prevent forgetting to lock. It is an object of the present invention to provide an extendable handrail device that can perform the above-described operation.

The telescopic handrail device according to the present invention includes a pipe-shaped handrail main body extending in the vertical direction,
A pipe-shaped support member that is fixed to the installation surface and is fitted to the handrail main body and supports the handrail main body so as to be slidable in the vertical direction;
A plurality of height adjusting holes formed in the peripheral surface of the handrail main body and having different heights;
A positioning pin that is supported so as to be displaceable in the radial direction of the handrail body and can be inserted into any one of the height adjusting holes, and a first biasing member that biases the positioning pin in the centrifugal direction; A locking device for restricting sliding of the handrail body with respect to the support member by inserting the positioning pin;
An operating member provided opposite to the locking device and displaceable between a lock position and a release position;
A lock permission that allows the positioning pin to be inserted into the height adjusting hole by forming a gap between the operating member and the outer peripheral surface of the handrail body when facing the positioning pin when the operating member is in the locked position. And
When the operation member is in the release position, the positioning member faces the positioning pin and contacts the outer peripheral surface of the handrail main body, thereby pressing the tip of the positioning pin protruding from the height adjusting hole inward. An unlocking part to be
And a second urging member that urges the operation member toward the lock position ”.

  Here, the length of the “handrail main body” is not particularly limited, but when the handrail main body is slid to its upper limit position, the height is higher than the user can hold in a standing posture. It is preferable that The number of “height adjustment holes” corresponds to the number of stop positions of the handrail body. For example, if there are only two stop positions of the handrail body, at least two height adjustment holes are provided. Part is required. Note that a plurality of “height adjusting holes” may be provided in the circumferential direction, and the positioning pins may be inserted through the respective matching holes.

  According to the telescopic handrail device of the present invention, the pipe-shaped handrail body extending in the vertical direction is fitted to the pipe-shaped support member fixed to the installation surface, and the handrail body is attached to the support member. On the other hand, it can slide in the vertical direction. That is, if the handrail main body is raised, the whole length becomes long, and if the handrail main body is lowered, the whole length becomes short. That is, the overall length can be expanded and contracted by the cooperation of the handrail main body and the support member.

  Incidentally, a locking device is fixed to the support member. The lock device includes a positioning pin and a first biasing member, and the positioning pin is biased in the centrifugal direction by the first biasing member. For this reason, when the tip of the positioning pin matches one of the height adjusting holes formed in the handrail main body, the positioning pin is inserted (penetrated) into the height adjusting hole. In this state, the movement of the handrail body is restricted by the positioning pins, and the handrail body cannot be slid in the longitudinal direction (that is, the vertical direction). In other words, it is locked.

  On the other hand, an operation member that can be displaced between the lock position and the release position is provided. When the operation member is in the lock position, the lock permission portion faces the positioning pin and forms a gap between the outer peripheral surface of the handrail body. To do. That is, the insertion (penetration) of the positioning pin into the height adjusting hole is allowed by forming a gap. On the other hand, when the operation member is in the release position, the lock release portion faces the positioning pin and contacts the outer peripheral surface of the handrail main body, so that the tip of the positioning pin protruding from the height adjustment hole portion is directed inward. Press. Then, the positioning pin does not protrude from the height adjusting hole, and the handrail body can be slid with respect to the support member. Even if the unlocking part is brought into contact with the outer peripheral surface of the handrail main body, the tip of the positioning pin may be positioned in the height adjusting hole, but if the tip of the positioning pin is rounded, By applying a force in the sliding direction to the handrail main body, the tip of the positioning pin can be deviated from the height adjusting hole, and the handrail main body can be slid vertically. .

  In the present invention, since the second urging member for urging the operation member toward the lock position is provided, the operation member is automatically released when the operation member is released after releasing the lock state at the release position. Return to the locked position. For this reason, an operation for returning to the lock position becomes unnecessary, and forgetting to lock can be prevented. Even if the operation member returns to the lock position, it is not locked until the positioning pin is inserted again, so that the handrail body can be slid without holding the operation member on the release position side. .

Further, in the telescopic handrail device of the present invention, “the operation member is a substantially annular member that is provided outside the handrail main body and is rotatably supported in the circumferential direction,
The lock permission portion and the lock release portion are formed on the inner peripheral surface of the operation member ”.

  According to the telescopic handrail device of the present invention, when the operation member is in the initial position (lock position), the lock permission portion formed on the inner peripheral surface faces the positioning pin, and there is a gap between the tip of the positioning pin. It is formed. On the other hand, when the operating member is rotated in the circumferential direction and displaced to the release position, the unlocking portion formed on the inner peripheral surface faces the positioning pin and presses the tip of the positioning pin. In this way, the operation member is formed in an annular shape, and it is possible to act as a lock permission part and a lock release part simply by forming an uneven part on the inner peripheral surface thereof, so switching between the locked state and the release thereof is possible. It can be realized with an extremely simple configuration.

Furthermore, when the above configuration is adopted, “the second urging member includes a coiled torsion spring,
It is preferable to employ a configuration in which one end of the torsion spring is fixed to the operation member and the other end is fixed to the installation surface or the support member.

  According to this, it becomes possible to urge the operation member supported so as to be rotatable toward the initial position (lock position) side by using the elastic force of the spring. That is, when the operation member is rotated against the elastic force of the torsion spring, the release member is brought into the release position. When the hand is released from the operation member after releasing the locked state, the operation member is returned to the initial position by the elastic force of the torsion spring. .

  In the telescopic handrail device of the present invention, it may be “further provided with a damper that is disposed in the handrail body and in the support member and suppresses the descending speed of the handrail body”.

  According to this, since the handrail main body can be lowered relatively slowly by the damper, for example, when the lock state is released at the use position, the handrail main body falls even if the handrail main body is not grasped. It won't break or surprise the bather with loud noises. In particular, when the handrail body falls down vigorously, even if the height adjustment hole formed in the handrail body and the tip of the positioning pin match each other, before the positioning pin is inserted (that is, locked). However, according to the present invention, since the handrail main body slowly descends, the positioning pin can be reliably inserted to be in the locked state.

  As described above, according to the telescopic handrail device of the present invention, the lock mechanism is composed of the positioning pin and the first urging member, so that the size and cost can be reduced. In addition, since the second urging member for urging the operation member toward the lock position is provided, the operation member can be automatically returned to the lock position, and no operation for returning to the lock position is required. It is possible to prevent forgetfulness. Furthermore, even if the operating member returns to the locked position, the unlocked state can be maintained, so that it is not necessary to hold the operating member at the released position, and the operability can be further improved.

  Hereinafter, a telescopic handrail device (hereinafter simply referred to as “handrail device”) according to an embodiment of the present invention will be described with reference to FIGS. 1 to 7. FIG. 1 is a perspective view showing a schematic configuration of the entire bathroom provided with the handrail device of the present embodiment, FIG. 2 is a front view showing a configuration of a bathing device having the handrail device, and FIG. 3 is a configuration of the handrail device. 4 is a cross-sectional view showing a state in which the handrail body of the handrail device is slid to the use position, FIG. 5 is an enlarged vertical cross-sectional view showing the configuration of the main part, and FIG. 5 is a cross-sectional view showing a configuration of a lock mechanism portion in FIG. 5, and FIG. 7 is a block diagram showing a functional control configuration related to light emission control.

  As shown in FIG. 1, a bathing apparatus 1 having a handrail device is incorporated in a counter 3 disposed in a bathroom 2, and operates a faucet body (not shown) such as a hot and cold water mixing tap, and a faucet body. Faucet lever 8, discharge pipe 9 for discharging hot water from the faucet body, right handrail device 12 disposed on the right side of the faucet lever 8, left handrail device 13 disposed on the left side of the faucet lever 8, etc. It comprises. In addition, the bathroom 2 is also provided with a mirror 6 attached to the bathtub 4 and the wall surface 5.

  Here, although the right handrail device 12 and the left handrail device 13 correspond to the telescopic handrail device of the present invention, since these are completely the same structure, only the right handrail device 12 will be described in detail below. Detailed description of the left handrail device 13 is omitted.

  As shown in FIGS. 2 and 3, the right handrail device 12 includes a handrail body 15 erected from the counter 3 in the vertical direction (vertical direction), and a support member that supports the handrail body 15 so as to be slidable in the vertical direction. 16, a fixing member 17 and a supporting leg portion 25 for fixing the supporting member 16, a grip portion 18 provided at the upper end of the handrail main body 15, and a holder 20 for holding a shower head 19 of a hand shower. I have. Further, a lock mechanism 22 for fixing the position (height) of the handrail main body 15 with respect to the support member 16, a lock release mechanism 23 for releasing the lock state of the lock mechanism 22, and a lowering speed of the handrail main body 15. The air damper 24 to suppress is also provided. Here, the counter 3 corresponds to the installation surface of the present invention, and the air damper 24 corresponds to the damper of the present invention.

  Specifically describing each configuration, the handrail main body 15 is composed of a pipe-shaped member having a thickness suitable for gripping, and a height adjusting hole (details are provided in the vicinity of the upper end and the lower end). (To be described later). The length of the handrail main body 15 is not particularly limited, but is set to about 45 cm in this example.

  The support member 16 is between a storage position (see FIG. 3) where most of the handrail body 15 is stored below the counter 3 and a use position (see FIG. 4) where the handrail body 15 protrudes from the counter 3. The handrail body 15 is slidably supported and is formed from a pipe-shaped member. The outer diameter of the support member 16 is slightly smaller than the inner diameter of the handrail main body 15, and the support member 16 is fitted into the handrail main body 15 so that the handrail main body 15 can be slid in the vertical direction. is doing. The length of the support member 16 is not particularly limited, but is set to about 37 cm in this example.

  The fixing member 17 is composed of an upper holding portion 26 and a lower holding portion 27, and the upper holding portion 26 is a cylindrical member provided in a penetrating portion of the handrail body 15 with respect to the counter 3 so as to surround the handrail body 15. And it has the flange 26a contact | abutted on the upper surface of the counter 3. FIG. The lower holding portion 27 is a cylindrical member fitted or screwed to the outer peripheral surface of the upper holding portion 26 and has a flange 27 a that comes into contact with the back surface of the counter 3. That is, the fixing member 17 is assembled to the counter 3 by sandwiching the counter 3 between the flange 26a and the flange 27a, and is configured to support the outer peripheral surface of the handrail body 15 by the inner peripheral surface of the upper holding portion 26. Yes. The support leg 25 is fitted into the lower end of the handrail main body 15 and supports the support member 16 in a standing state by fixing the flange 25 a to the floor surface of the bathroom 2.

  The grip portion 18 is provided at the upper end of the handrail main body 15 and functions as a handle for raising and lowering the handrail main body 15. The grip portion 18 has a substantially oval shape projecting forward, and a lower portion thereof is fitted into an upper end portion of the handrail main body 15 and fastened by an attachment screw 29 penetrating the handrail main body 15.

  Further, the entire gripping portion 18 is formed of a light transmissive member (for example, acrylic). That is, the translucent part 28 is formed over the entire holding part 18. On the bottom surface of the grip portion 18, a recess 30 made of a relatively small depression is formed, and the light emitting diode 31 is embedded in the recess 30. That is, it is possible to perform indirect illumination of the bathroom 2 by irradiating the light emitted from the light emitting diode 31 to the ceiling of the bathroom 2 through the light transmitting portion 28. In addition, since the entire gripping portion 18 of this example is formed of a light transmissive member, the gripping portion 18 itself appears to shine, and the presence of the gripping portion 18 can be highlighted. The light emitting diode 31 emits visible light by applying a forward bias voltage to a semiconductor PN junction. In this example, a light emitting diode having a predetermined emission color is used. In addition, a power supply line 32 is connected to the light emitting diode 31, and the power supply line 32 is wired through the handrail body 15 and the support member 16, and is a through hole formed in the peripheral surface of the support leg 25. 33 is sent to the outside.

  On the other hand, the holder 20 is attached below the grip portion 18 in the handrail main body 15 and has a C-shape in plan view with the front side open. The holder 20 is connected to a swing mechanism 36 embedded in the handrail main body 15. Since the swing mechanism 36 has a well-known configuration, a detailed description thereof is omitted here. However, by attaching the swing mechanism 36 via the swing mechanism 36, the holder 20 can be tilted in the vertical direction and the horizontal direction. Convenience when taking a shower is enhanced.

  Moreover, the bathing apparatus 1 of this example is equipped with the control apparatus for controlling the lighting state of the light emitting diode 31. FIG. As shown in FIG. 5, the control device includes a contact detection means 50 for detecting that the bather has touched the bathroom equipment such as the faucet lever 8, the handrail main body 15, or the grip portion 18, and a commercial power supply (AC100V). And a light emission control circuit 52 having a delay timer 51. Based on the output of the contact detection means 50, the light emission control circuit 52 turns on the light emitting diode 31 (right light emitting diode 31a) of the right handrail device 12 and the light emitting diode 31 (left light emitting diode 31b) of the left handrail device 13, and delays it. After the time set by the timer 51 elapses, these light emitting diodes 31 are turned off. The configuration of the contact detection means 50 is not particularly limited. For example, the surface of the target bathroom facility is formed of a conductive material, and the change in capacitance at that portion is changed to the change in voltage. It is possible to adopt a configuration that converts and determines the presence or absence of contact.

  As shown in FIGS. 5 and 6, the lock mechanism 22 regulates the sliding of the handrail body 15 by inserting a positioning pin 41 through a height adjusting hole 40 drilled in the peripheral surface of the handrail body 15. To do. More specifically, the handrail body 15 includes a plurality of height adjustment holes 40 having different heights (specifically, the upper height adjustment hole 40 corresponding to the storage position and the use position). Corresponding lower side height adjustment holes 40) are drilled. Each height is provided with a pair of height adjusting holes 40 facing each other in the radial direction.

  The lock mechanism 22 includes a pair of positioning pins 41 arranged on a straight line and a coil spring-like first biasing member 42 that biases each positioning pin 41 in the centrifugal direction. The positioning pin 41 has a tip formed in a spherical shape, and is supported so as to be displaceable in the radial direction of the handrail body 15. That is, the positioning pin 41 can be inserted into any one of the height adjustment holes 40 by the biasing force of the first biasing member 42. The lock mechanism 22 is sandwiched between upper and lower air dampers 24 and attached to the upper end of the support member 16 in a fixed state. For this reason, the tip of the positioning pin 41 is in contact with the inner peripheral surface of the handrail main body 15 until it matches one of the height adjustment holes 40, and either of the height adjustment holes 40. If it matches, it will be inserted in the height adjustment hole 40, and will be in the state which protruded outside from the surrounding surface of the handrail main body 15. FIG. In this state, the handrail body 15 cannot be slid in the vertical direction with respect to the support member 16, and a so-called locked state is obtained. In this example, the height adjustment hole 40 and the positioning pin 41 are set to coincide with each other when the handrail body 15 is in the use position and the storage position.

  The lock release mechanism 23 is provided on the outer side of the handrail main body 15 and includes an annular operation member 43 that is rotatably supported between the lock position and the release position in the circumferential direction. A finger hooking portion 46 protruding outward is integrally formed on the outer peripheral surface of the operation member 43, and the operation member 43 can be easily rotated by hooking a finger. On the inner peripheral surface of the operation member 43, lock permission portions 44 and lock release portions 45 are alternately formed at predetermined intervals. The lock permission part 44 faces the tip of the positioning pin 41 when the operation member 43 is in the lock position, and forms a gap between the outer peripheral surface of the handrail main body 15, thereby positioning the height adjustment hole 40. This is the part that allows the insertion of the pin 41. On the other hand, the lock release portion 45 faces the tip of the positioning pin 41 when the operation member 43 is in the release position, and comes into contact with the outer peripheral surface of the handrail main body 15 so as to protrude from the height adjusting hole 40. It is a part which presses the front-end | tip of 41 toward inward. That is, by making the positioning pin 41 not projecting, the tip of the positioning pin 41 can be deviated from the height adjustment hole 40. That is, the lock state is released, and the handrail main body 15 can be slid with respect to the support member 16.

  In this example, a torsion spring 47 is provided to urge the operating member 43 toward the lock position. The torsion spring 47 is formed in a coil shape, and one end (upper end) side is locked to the inner peripheral surface of the operation member 43, and the other end (lower end) side is locked to the upper holding portion 26. Therefore, an urging force is generated in the circumferential direction of the handrail main body 15, and the finger hooking portion 46 of the operation member 43 operated to the release position returns to the initial position (lock position). Here, the lock mechanism 22 corresponds to the lock device of the present invention, and the torsion spring 47 corresponds to the second urging member of the present invention.

  Next, the usage method and effects of the right handrail device 12 and the left handrail device 13 of this example will be described. Since the handrail body 15 erected in the vertical direction from the counter 3 is supported by the support member 16 so as to be slidable in the vertical direction, when the handrail body 15 is moved to the use position as shown in FIG. The main body 15 is greatly protruded from the counter 3 and can be used as a handrail. That is, it becomes possible for the bather to lean on, grab or hold the handrail main body 15.

  In particular, since the pair of handrail main bodies 15 are separately disposed on both sides of the faucet lever 8 in the counter 3, the bather can grasp the pair of handrail main bodies 15 in parallel with the left and right hands, respectively. . Accordingly, the right and left balance is improved, and it is possible to avoid an unstable state in which the body rotates around one handrail main body 15. Moreover, since stability is improved, a body can be supported even if it is not gripped with strong force, and a bather's burden can be reduced. Furthermore, it is possible to wipe away the anxiety about getting up and sitting down in the washroom. Further, since the bather can stand up or sit down with the faucet lever 8 and the discharge pipe 9 as front, it is possible to prevent the faucet lever 8 from being operated unexpectedly, and the bather's safety. It is possible to further improve the properties.

  On the other hand, as shown in FIG. 3, when the handrail main body 15 is moved to the storage position, most of the handrail main body 15 is stored below the counter 3. For this reason, a pair of handrail main body 15 does not become obstructive, and it becomes possible to make the bathroom 2 feel wide.

  Moreover, since the grip part 18 which functions as a handle is provided at the upper end of the handrail body 15, the handrail body 15 can be moved up and down by grasping the grip part 18. Even when the handrail main body 15 is stored, the gripping portion 18 protrudes from the counter 3, so that the handrail main body 15 can be easily pulled out from the storage position.

  Incidentally, a lock mechanism 22 is fixed to the support member 16. For this reason, as shown in FIG. 5 or FIG. 6A, when the tip of the positioning pin 41 matches one of the height adjustment holes 40 formed in the handrail body 15 at the use position or the storage position. The positioning pin 41 is inserted (penetrated) into the height adjusting hole 40. In this state, the movement is restricted by the positioning pin 41, and the handrail body 15 cannot be slid in the longitudinal direction. In other words, it is locked.

  On the other hand, an operation member 43 is provided. As shown in FIG. 6B, when the operation member 43 is rotated to the release position, the lock release portion 45 faces the positioning pin 41 and the outer peripheral surface of the handrail main body 15. , The tip of the positioning pin 41 protruding from the height adjusting hole 40 is pressed inward. Then, the positioning pin 41 does not protrude from the height adjusting hole 40, and the handrail body 15 can be slid with respect to the support member 16. Since the tip of the positioning pin 41 is formed in a spherical shape, the tip of the positioning pin 41 easily deviates from the height adjustment hole 40 by applying a force in the sliding direction to the handrail body 15. The handrail body 15 can be slid up and down.

  In addition, since the torsion spring 47 that biases the operation member 43 toward the lock position is provided, the operation member 43 is automatically moved to the lock position when the operation member 43 is released after the lock state is released at the release position. Return to. For this reason, an operation for returning to the lock position becomes unnecessary, and forgetting to lock can be prevented. Even if the operation member 43 returns to the lock position, the handrail main body 15 is slid without holding the operation member 43 on the release position side because the positioning pin 41 is not locked until it is inserted again. Is possible.

  Further, in this example, since the air damper 24 is provided between the handrail main body 15 and the support member 16, the handrail main body 15 can be lowered relatively slowly. Even when the handrail main body 15 is not gripped when the handrail is released, the handrail main body 15 is not dropped and damaged, or the bather is not surprised by a loud sound. Further, since the handrail body 15 is slowly lowered, the positioning pin 41 can be reliably inserted into the height adjusting hole 40 to be in the locked state.

  By the way, in this example, since the light emitting diode 31 is embedded upward on the bottom surface of the gripping portion 18, when it is detected that a predetermined bathroom facility is touched, the light emitting diode 31 is lit and gripped. Light is emitted to the ceiling of the bathroom 2 through the part 18. For this reason, indirect lighting of the bathroom 2 can be performed, and a healing space can be created by soft light. In particular, the grip portion 18 is not shielded regardless of whether the handrail main body 15 is in the use position or the storage position, so that the ceiling can be irradiated with light regardless of the position of the handrail main body 15. In other words, even when the handrail body 15 is housed, it can be used as a lighting fixture. Moreover, when the protrusion length of the handrail main body 15 changes, the distance between the ceiling and the light emitting diode 31 changes, and thus the brightness of the indirect illumination and the irradiation range change. That is, since the way of receiving illumination can be changed, the effect as indirect illumination can be further enhanced.

  Further, since light is emitted from the top surface or the peripheral surface of the gripping portion 18, it is possible to easily grasp the height of the gripping portion 18, that is, the length of the handrail main body 15, and grip the handrail main body 15. It is possible to suppress damage or trying to approach the vehicle despite being stored. That is, it becomes possible to ensure the safety of the bather.

  The light emitting diode 31 is automatically turned off after a predetermined time. For this reason, useless power consumption due to forgetting to turn off can be prevented.

  Further, since the handrail main body 15 is provided with the holder 20, the handrail main body 15 can function as a support column for holding the shower head 19, and the convenience of the handrail main body 15 can be further enhanced. Become. In particular, the height of the shower head 19 can be freely changed by changing the protruding length of the handrail body 15. Further, when the protruding lengths of the right and left handrail main bodies 15 are made different from each other, the height at which the shower head 19 is supported can be changed. Therefore, according to this, the shower can be comfortably used even when the bather is sitting or standing. Further, since the shower head 19 can be supported on either the left or right handrail main body 15, the support range of the shower head 19 in the left-right direction is widened. For example, the shower head 19 is taken from the left side after taking a shower from the right side of the body. Usage is also possible.

  The best mode for carrying out the present invention has been described above, but the present invention is not limited to this embodiment, and various modifications can be made without departing from the spirit of the present invention as described below. Improvements and design changes are possible.

  That is, in the telescopic handrail device of the above-described embodiment, the handrail main body 15 is erected on the counter 3, but may be erected on the floor surface of the bathroom 2. However, if the handrail main body 15 is made to stand up from the counter 3 as in the above embodiment, the handrail main body 15 is less likely to interfere with hair washing and the like, and the protruding length of the handrail main body 15 at the use position is relatively short. , Can reduce the feeling that the bathroom 2 is narrow. In addition, it is also possible to apply the telescopic handrail device of the present invention to a handrail used outside the bathroom 2.

  Moreover, in the telescopic handrail device of the above-described embodiment, the one provided with the pair of handrail devices 12 and 13 is shown, but only one handrail device may be provided. However, if the right handrail device 12 and the left handrail device 13 are provided on both sides of the faucet lever 8 as in the above embodiment, the safety of the bather can be enhanced and a sense of security can be given. Moreover, since light is radiated | emitted from the two holding parts 18, the brightness of indirect illumination can be increased and the utility value as illumination can be raised. In addition, if the emission colors of the light emitted from the gripping portions 18 are made different from each other, it is possible to further enhance the effect as an electric decoration.

  Moreover, in the telescopic handrail device of the above-described embodiment, the handrail main body 15 has been shown to be fixable between the lower limit storage position and the upper limit use position (that is, adjustable in two stages). The use position may be further divided into a plurality of stages so as to be adjustable at a plurality of heights. This configuration can be easily realized by increasing the number of height adjusting holes 40 formed in the handrail main body 15.

  In the telescopic handrail device of the above embodiment, the lock allowing portion 44 and the lock releasing portion 45 are formed on the inner peripheral surface of the operation member 43. However, the lock allowing portion and the lock releasing portion are separate from the operation member. It may be configured by a member, and the lock allowing portion or the lock releasing portion may be opposed to the positioning pin 41 in conjunction with the movement of the operation member. However, if formed integrally as in the above-described embodiment, switching between the locked state and the release thereof can be realized with a very simple configuration, and further miniaturization and cost reduction can be achieved.

  Moreover, in the telescopic handrail device of the above embodiment, the faucet lever 8 and the discharge pipe 9 and the pair of handrail devices 12 and 13 are disposed adjacent to the bathtub 4, but the position is particularly limited. For example, as shown in FIG. 8, you may make it arrange | position on the wall surface which faces the bathtub 4. As shown in FIG. In this case, the faucet lever 8 and the discharge pipe 9 may be attached to the wall surface.

  Furthermore, in the telescopic handrail device of the above-described embodiment, the handrail main body 15 is erected on the counter 3, but it may be erected on the floor surface of the bathroom 2 as shown in FIG. However, if the handrail main body 15 is made to stand up from the counter 3 as in the above embodiment, the handrail main body 15 is less likely to interfere with hair washing and the like, and the protruding length of the handrail main body 15 at the use position is relatively short. , Can reduce the feeling that the bathroom 2 is narrow.
