  1 to 4 show an embodiment of the present invention. 1 to 4, a handrail type shower apparatus 1 is installed on, for example, a wall surface W of a bathroom wash basin 1 a, a hollow handrail body 2 arranged in the vertical direction, and water and hot water pipes from a water pipe L. A mixing means 3 provided in the handrail body 2 to mix hot water from H, a hand shower 6 and an upper shower 7 comprising a shower hose 4 and a shower head 5 provided downstream of the mixing means 3; There is provided switching means 8 for switching the hot water mixed by the mixing means 3 to a state of supplying to the hand shower 6 or a state of supplying to the upper shower 7. 5a is a shower hook provided on the wall surface W at a predetermined height position.

The handrail body 2 includes an outer pipe 11 having a water introduction port 9 and a hot water introduction port 10 communicating with the water pipe L and the hot water pipe H through joints 9a and 10a, respectively, and an upstream end inside the outer pipe 11 An inner pipe 12 provided so that 12a is connected to the mixing means 3 and an outer diameter identical to that of the outer pipe 11, a downstream end 14b is connected to the upper shower 7, and the inner pipe 12 The upstream end portion 14 a is connected to the downstream end portion 11 b of the outer tube 11 so as to communicate with the downstream end 12 b of the outer tube 11 through the joint 13. And the outer tube | pipe 11 and the connecting pipe 14 are set to the magnitude | size which can be used as a handrail installed in a bathroom.
The connecting pipe 14 and the inner pipe 12 form a hot / cold water supply flow path i toward the switching means 8. The switching means 8 is provided in the middle of the connecting pipe 14.
Further, water is introduced from the switching means side to the mixing means side between the outer pipe 11 and the inner pipe 12, thereby preventing heat from being transmitted from the hot water supply flow path i to the outer pipe 11. An annular water introduction path j is formed.
The connecting pipe 14, the outer pipe 11, and the inner pipe 12 are commercially available pipes. In this example,
(1) As the connection pipe 14, the outer pipe 11, and the inner pipe 12, commercially available pipes having a circular cross section are used. In order to make the connecting tube 14 and the outer tube 11 function more effectively as handrails, it is preferable to provide a slip prevention member so as to cover these outer surfaces. Examples of the anti-slip member include a semi-rigid member made of a resin such as a silicone rubber material or soft vinyl chloride in order to provide flexibility. Thereby, the connection pipe 14 and the outer pipe 11 covered with the anti-slip member can be configured to be firmly gripped. Further, by adding an antibacterial agent to the resin, it is possible to prevent the propagation of various bacteria.
(2) As the connection pipe 14, the outer pipe 11, and the inner pipe 12, commercially available pipes having a rectangular vertical cross section may be used.

The mixing means 3 is provided with a temperature setting means (temperature setting handle) 16 for setting the hot water temperature to be ejected from the hand shower 6 or above shower 7, hot water corresponding to the temperature set by the temperature setting means 16 A temperature adjustment unit 17 having an automatic temperature adjustment function for mixing is mainly provided. The temperature setting means 16 and the temperature adjustment unit 17 are also commercially available. The temperature adjustment unit 17 houses a valve body / thermoelement housing case 18 and a transmission mechanism for converting the pivoting motion of the plug rod R by the temperature setting means 16 into horizontal motion and transmitting this horizontal motion to the thermoelement side. And a case 15. The temperature setting means 16 is connected to the transmission mechanism via the plug rod R.

  The valve element / thermoelement storage case 18 is fitted into the outer tube 11 through an opening A formed in the upstream end portion 11 a of the outer tube 11. In the case 18 of the temperature adjustment unit 17, a mixing chamber M for mixing water from the water pipe L and hot water from the hot water pipe H is formed, and the temperature of the hot water mixed in the mixing chamber M is set. A thermowax 19 that expands and contracts under the influence is accommodated, and a thermoelement 20 that expands and contracts as the wax 19 expands and contracts is accommodated. Further, along with the expansion and contraction of the thermoelement 20 The valve body 23 in which the ratio of closing the communication port 21 communicating with the water pipe L and the communication port 22 communicating with the hot water pipe H provided in different locations of the mixing chamber M is changed. It is stored. The ratio of the flow rate of hot water from the water pipe L to the mixing chamber M and the hot water pipe H changes with the change in the ratio of closing the two communication ports 21 and 22 by the valve body 23. Thus, the temperature of the hot water mixed in the mixing chamber M is changed.

  In the temperature adjustment unit 17 having the above-described configuration, when the temperature of the hot water mixed in the mixing chamber M is not the temperature corresponding to the temperature set by the temperature setting means 16, the mixing chamber M The wax expands and contracts under the influence of the temperature of hot water in the interior, the thermo element 20 expands and contracts, and the valve body 23 moves. With this movement, water from the water pipe L and The ratio of the flow rate of hot water introduced from the hot water pipe H into the mixing chamber M changes, and the temperature of the hot water mixed in the mixing chamber M approaches the temperature corresponding to the temperature set by the temperature setting means 16. Will eventually match. And the hot water of this preset temperature flows through the hot water supply flow path i. In this embodiment, the thermo element 20 is installed so that the position of the communication port 22 provided in the mixing chamber M coincides with the most upstream end of the region where the thermo wax 19 is stored. Therefore, there is an advantage that the automatic temperature adjustment operation of the temperature adjustment unit 17 can be performed quickly.

  The upper shower 7 includes a shower plate 7 a having a plurality of shower sprinkling ports 7, and a hollow bar 7 b for attaching the upper shower connecting the shower sprinkling port 7 and the hot water supply channel i. The upstream end of the bar 7 b is connected to the downstream end 14 b of the connecting pipe 14. The outer diameter of the bar 7b is smaller than the outer diameter of the connecting pipe 14, and commercially available bars 7b and shower plates 7a are used.

  The switching means 8 is a switching handle 30 and a switching unit that can be switched to a state of flowing hot water in the hot water supply flow path i to the shower hose 4 or a state of flowing to the bar 7b in conjunction with the switching operation of the switching handle 30. It consists of and.

The joints 9a and 10a have the same structure as the eccentric tube described in JP-A-2003-336300 and are commercially available products.
For example, the joint 9a on the water supply side has a connection part 33 with the outer pipe 11 at one end and a connection part 34 with the water pipe L at the other end, and the center of both connection parts 33 and 34 is about several millimeters. A joint body 35 is provided so as to be displaced. Reference numeral 36 denotes a cover made of a synthetic resin that slidably covers the joint body 35. The cover 36 can be separated into two halves 37, 38, and has a guide groove 38a shaped along the outer surface 35a of the joint body 35. One half body 38 has. Reference numeral 39 denotes a single flow rate adjusting plug provided on the side surface of the joint body 35. The flow rate can be adjusted with a screwdriver or the water from the water pipe L can be stopped. The other half body 37 has an opening 40 for exposing the flow rate adjusting plug 39 to the outside.
On the other hand, the joint 10a on the hot water supply side has the same structure as the joint 9a, and the joint 10a also has a cover 42 made of a synthetic resin that slidably covers the joint body 41. This cover 42 can also be separated into two halves 42a and 42b with the same structure as the cover 36. The cover 42 can enhance the safety of the user against burns.
Also, since the cover 36 covers almost the entire joint 9a, the fitting body 35 without the buffing process can be used, which is somewhat unsatisfactory. It is possible to avoid the situation that yields due to mass production of products. The same applies to the joint body of the joint 10a.
Although not shown, the halves 37 and 38 constituting the cover 36 and the two halves 42a and 42b constituting the cover 42 have drain holes. Therefore, when using a shower or the like, hot water accumulated in the covers 36 and 42 can always be discharged out of the covers 36 and 42 through the drain holes, so that a long life can be maintained, and it is effective in terms of hygiene.

  43 and 44 are handrail type shower apparatus mounting members provided on the bar 7b, and the handrail type shower apparatus 1 is installed on the wall W of the washing place through the members 43 and 44.

  Thus, since the connecting pipe 14 and the outer pipe 11 of the shower apparatus 1 are provided at predetermined height positions, and these are also used as handrails, the operation in the bathroom washing area 1a can be assisted.

  In addition, it is not necessary to provide a new handrail on the wall W of the bathroom washing area 1a, and the space of the bathroom can be used effectively, and a situation where the body hits the handrail can be avoided and effective as a barrier free.

  In addition, since existing pipes 14 and outer pipes 11 used as handrails are used, and existing bars 7b, shower plates 7a, and joints 9a and 10a are also used, there is no need to separately form them separately. Can be reduced.
