Shower device and shower system

Technical Field

The invention relates to a shower device and a shower system.

Background

Conventionally, a shower system for showering a user while sitting is known (for example, refer to patent document 1). In patent document 1, a shower system includes a chair and a shower unit (shower device).

The shower unit includes a main body, a headrest portion, a lumbar portion, and a pair of arms (a first arm portion and a second arm portion). The main body is formed in a vertically long substantially elliptical plate shape and is attached to the back surface of the chair. The headrest portion is mounted on an upper end of the main body. The lumbar region is mounted to the lower end of the main body. The pair of arms is mounted to be rotatable back and forth with respect to the main body. The pair of arms can be rotated between a storage state (retracted state) in which both sides of the upper portion of the main body are along the side portions of the main body and a use state (specific state) in which the arms are tilted forward and extended.

A shower head (discharge hole) is attached to the body, the headrest portion, the lumbar portion, and the pair of arms so as to be capable of swinging.

In order to use the shower system configured as described above, first, the user sets the shower system at a desired position in the bathroom. A shower hose branched from a shower path of a faucet of a bathroom is connected to the shower unit. The pair of arms is rotated to spread laterally, and the pair of arms is used. A user sits in a chair of the shower system and hot water is sprayed from the showerheads of the pair of arms.

Thus, the user can take a shower while sitting on the chair.

Problems to be solved by the invention

However, when both arms are in the stored state, both arms may interfere with the armrests of the chair, the user sitting on the chair, and the like.

The present invention has been made in view of the above-described problems, and an object thereof is to provide a shower apparatus that suppresses interference of both arms with an armrest of a chair, a user sitting on the chair, and the like when both arms are in a retracted state, and a shower system including the shower apparatus.

Means for solving the problems

In order to solve the above problems, the present invention proposes the following.

The shower apparatus of the present invention is characterized by comprising: a main body having a connection part to which water is supplied from the outside; and a first arm portion and a second arm portion that are rotatably supported by the main body so that base end portions thereof sandwich the main body in a first direction along a horizontal plane and that are formed with discharge holes that discharge the water supplied from the connection portion to the inside to the outside, wherein when the first arm portion and the second arm portion in a retracted state are viewed in a second direction orthogonal to the first direction along the horizontal plane, the first arm portion and the second arm portion are arranged so as to be gradually separated from each other in a downward direction, and the first arm portion and the second arm portion in a specific state extend forward from the main body and further extend downward from a front end extending forward.

According to the present invention, the user sits on the chair and takes a shower by receiving water supplied from the connection part and discharged from the discharge holes of the first and second arm parts.

On the other hand, when both the arm portions are not used, the first arm portion and the second arm portion are set to the retracted state. In this case, when the arm portions are viewed in the second direction, the arm portions are arranged so as to be gradually separated from each other from the base end portions in a downward direction, and therefore, the arm portions can easily avoid the armrest of the chair, the user sitting on the chair, and the like on the outer side in the first direction. Therefore, when the two arm portions are in the retracted state, it is possible to suppress the two arm portions from interfering with the armrests of the chair, the user sitting on the chair, and the like.

In the shower apparatus, the shower apparatus may further include: in a specific state in which the distal end portions of the first arm portion and the second arm portion are raised higher than the distal end portions of the first arm portion and the second arm portion in the retracted state, the first arm portion and the second arm portion are arranged to extend in the up-down direction, respectively, when the first arm portion and the second arm portion are viewed from the second direction.

According to the present invention, when both arms are set in the specific state in the first direction, the user can take a shower with water more effectively than when both arms are set in the retracted state.

In addition, in the shower apparatus, the shower apparatus may be: a base end portion of the first arm portion is rotatably supported on an end portion on one side in the first direction on the main body about a first axis, and a base end portion of the second arm portion is rotatably supported on an end portion on the other side in the first direction on the main body about a second axis, and the first axis and the second axis are inclined in opposite directions to each other with respect to an up-down direction so as to be separated from each other as viewed from the second direction.

According to the present invention, the first arm portion and the second arm portion can be arranged so as to be gradually separated from each other as they go downward in the retracted state and so as to extend in the vertical direction in the specific state, as viewed from the second direction, by a simple configuration in which the first axis and the second axis are inclined.

Another shower apparatus according to the present invention includes: a main body having a connection part to which water is supplied from the outside; and a first arm portion and a second arm portion that are rotatably supported by the main body so that base end portions thereof sandwich the main body in a first direction along a horizontal plane, and that are formed with discharge holes that discharge the water supplied from the connecting portion to the inside to the outside, wherein the first arm portion and the second arm portion extend forward from the main body and further extend downward from a front end extending forward.

Further, a shower system according to the present invention includes: the shower apparatus of any one of the above; and a chair for mounting the main body.

According to the present invention, a shower system can be configured using the following shower apparatus: when both the arm portions are in the retracted state, the interference of both the arm portions with the armrest of the chair, the user sitting on the chair, and the like is suppressed.

Effects of the invention

According to the shower apparatus and the shower system of the present invention, when both the arm portions are in the retracted state, it is possible to suppress interference of both the arm portions with the armrest of the chair, the user sitting on the chair, and the like.

Detailed Description

Hereinafter, an embodiment of the shower system according to the present invention will be described with reference to fig. 1 to 13.

As shown in fig. 1, the shower system 1 of the present embodiment includes a chair 11 and a shower device 41.

The chair 11 may use a known chair. The chair 11 is preferably water-resistant to enable use in a bathroom as well. For example, the chair 11 includes legs 12, a seat 13, a backrest 14, and armrests 15.

Hereinafter, the left-right direction (first direction) X and the front-back direction (second direction) Y of the user sitting on the chair 11 will be described as references. The left-right direction X is a direction along a horizontal plane. The front-rear direction Y is a direction along the horizontal plane and orthogonal to the left-right direction X. One side in the left-right direction X is a right side X1, and the other side in the left-right direction X is a left side X2. One side in the front-rear direction Y is a front Y1, and the other side in the front-rear direction Y is a rear Y2.

The seat 13 includes a pair of seat plates 17 and a connecting member 18 connecting the pair of seat plates 17.

The seat plate 17 is formed in a plate shape having a thickness direction Z in the vertical direction. The seat plate 17 has a rectangular shape in a plan view as viewed from the vertical direction Z. The pair of seat plates 17 are arranged side by side with a space therebetween in the left-right direction X.

The connecting member 18 has a U-shape with an upper opening when viewed from the front-rear direction Y. The connecting member 18 extends in the front-rear direction Y and is disposed below the pair of seat plates 17. The connecting member 18 connects the lower surfaces of the pair of seat plates 17 to each other.

The pair of seat plates 17 and the coupling member 18 are integrally formed of, for example, resin.

The upper ends of the rear legs 21 are fixed to the rear end portions of the pair of seat plates 17. For example, the rear leg 21 is formed of a tube material such as aluminum or stainless steel. The rear leg 21 is inclined so as to gradually go to the rear Y2 as it goes downward. The pair of rear legs 21 are arranged side by side with a space therebetween in the left-right direction X. A resin cap 22 is attached to a lower end of each rear leg 21.

The pair of rear legs 21 are coupled to each other by a coupling member 23.

A frame 26 formed of a hard pipe material such as aluminum or stainless steel into a U shape is rotatably connected to the upper end portions of the pair of rear legs 21. More specifically, the frame 26 includes a pair of support pieces 27 arranged in the left-right direction X at intervals, and a coupling piece 28 that couples upper portions of the pair of support pieces 27 to each other.

The support piece 27 is inclined so as to gradually face the front Y1 as it faces downward. Each support piece 27 is rotatably supported at an intermediate portion in the longitudinal direction by a hinge 29 (one hinge 29 is not shown) at an upper end portion of the rear leg 21. The support piece 27 is rotatable about an axis in the left-right direction X with respect to the upper end portion of the rear leg 21. The angle between the rear leg 21 and the support piece 27 is limited by the hinge 29 so as not to open at an angle greater than a predetermined value.

A cap 32 made of resin is attached to a lower end of each support piece 27.

The pair of support pieces 27 are coupled to each other by a coupling member 30. The coupling member 30 is formed in a bar shape and extends in the left-right direction X. The leg portion 12 is formed by a portion of the pair of support pieces 27 below the hinge 29 and the pair of rear legs 21.

The connecting piece 28 extends in the left-right direction X. The connecting piece 28 may be made of a hard resin.

As shown in fig. 1 and 2, the back plate 36 is disposed in front Y1 of the connecting sheet 28. The back plate 36 is curved so as to project toward the rear Y2 when viewed in the vertical direction Z. The back plate 36 is fixed to the connecting piece 28 of the frame 26 by bolts or the like, not shown. The backrest 14 is constituted by the back plate 36, the connecting piece 28, and the portion of the pair of support pieces 27 above the hinge 29. The seat unit 13 is disposed in front Y1 of the backrest unit 14.

In the present embodiment, the chair 11 is provided with a pair of armrests 15. The armrest 15 extends in the front-rear direction Y. The pair of armrests 15 are arranged side by side with a space therebetween in the left-right direction X. The rear end of each armrest 15 is rotatably supported by a portion of the support piece 27 above the hinge 29. The armrest 15 is rotatable about an axis along the left-right direction X.

The armrest 15 can rotate upward from the state shown in fig. 1, but is restricted from rotating downward from the state shown in fig. 1.

The chair 11 thus constructed can be folded from the unfolded state shown in fig. 1. Specifically, the pair of support pieces 27 are rotated about the hinge 29, and the pair of support pieces 27 are arranged substantially parallel to the pair of rear legs 21. The front end of each armrest 15 is moved upward, and the pair of armrests 15 are arranged substantially parallel to the pair of support pieces 27.

Through the above steps, the chair 11 is folded. The chair 11 may not be foldable, and may not include the armrest 15.

The shower device 41 includes a main body 42, a first shower arm (first arm) 43A, a second shower arm (second arm) 43B, and a connection portion 44. The shower arms 43A and 43B shown in fig. 1 are in the later-described use states P1A and P1B.

The shower arms 43A and 43B are disposed so as to sandwich the body 42 in the left-right direction X. The first shower arm 43A is disposed at the right side X1 of the main body 42, and the second shower arm 43B is disposed at the left side X2 of the main body 42.

In the present embodiment, the configuration of the first shower arm 43A and the configuration of the second shower arm 43B are plane-symmetrical with respect to a reference plane defined to be orthogonal to the left-right direction X between the shower arms 43A and 43B. Therefore, the structure of the first shower arm 43A is represented by adding an english capital letter "a" to a numeral or a numeral and an english lowercase letter. The structure of the second shower arm 43B corresponding to the first shower arm 43A is represented by adding an english capital letter "B" to the same numeral or numeral and english lowercase letter as the first shower arm 43A. Therefore, redundant description is omitted. For example, the front end part 46A of the first shower arm 43A and the front end part 46B of the second shower arm 43B are structures plane-symmetrical to each other.

As shown in fig. 3 and 4, the first shower arm 43A includes a front end member (front end portion) 46A, a coupling member (coupling portion) 47A, and a base end member (base end portion) 48A. In addition, in fig. 3, the main body 42 is shown by a two-dot chain line. In fig. 4, the cross-sectional shape of front end component 46A is schematically illustrated.

The front end member 46A is formed in a tubular shape with a front end portion sealed. The front end member 46A is inclined so as to gradually face downward toward the front Y1. The distal end member 46A is provided with a discharge hole 50A penetrating the wall of the distal end member 46A. The drain hole 50A drains the water W supplied to the interior of the front end member 46A to the outside. In the present specification, water is general water regardless of whether the temperature is high or low, and means water at normal temperature, hot water at a temperature used for showering, and the like.

The direction in which the discharge hole 50A is formed will be described later.

As shown in fig. 5, a coupling groove (fitting portion) 51A is formed in the inner peripheral surface of the rear end portion of the distal end member 46A. In fig. 5 and fig. 6 described later, the front end member 46A and the base end member 48A are shown by two-dot chain lines. The coupling groove 51A is formed along the entire inner peripheral surface of the front end member 46A.

The front end member 46A is formed of a relatively hard material such as acrylonitrile-butadiene-styrene resin (ABS) resin or polypropylene (PP) resin.

As shown in fig. 5 and 6, the coupling member 47A includes a coupling portion main body (main body portion) 56A, a distal end side flange portion (fitting target portion) 57A, and a proximal end side flange portion (fitting target portion) 58A.

The coupling portion body 56A is formed in a cylindrical shape. The coupling part main body 56A is curved so as to be convex toward the front Y1 and upward.

An annular member 59A is coaxially fixed to a distal end portion of the coupling portion body 56A (an end portion of the coupling portion body 56A in the axial direction). The inner diameter of the annular member 59A and the inner diameter of the distal end portion of the coupling portion body 56A are equal to each other. The annular member 59A has an outer diameter smaller than the outer diameter of the distal end of the coupling body 56A. The distal flange portion 57A is provided on the outer peripheral surface of the distal end of the annular member 59A. The distal-side flange portion 57A projects radially outward from the outer peripheral surface of the annular member 59A toward the annular member 59A. The outer diameter of the distal end flange portion 57A is smaller than the outer diameter of the distal end of the coupling portion body 56A. The front-end flange 57A is formed along the entire circumferential surface of the annular member 59A. The outer diameter of the distal end portion of the distal end side flange portion 57A gradually decreases toward the front Y1.

The distal end flange portion 57A is fitted in the coupling groove 51A of the distal end member 46A. The coupling member 47A and the distal member 46A are fitted to each other by a simple structure of the distal flange portion 57A and the coupling groove 51A.

An annular member 60A is coaxially fixed to a rear end portion of the coupling portion body 56A (an end portion of the coupling portion body 56A in the axial direction). The inner diameter of the annular member 60A and the inner diameter of the rear end portion of the coupling portion body 56A are equal to each other. The annular member 60A has an outer diameter smaller than the outer diameter of the rear end of the coupling body 56A. The base end side flange portion 58A is provided on the outer peripheral surface of the rear end portion of the annular member 60A. The base end side flange portion 58A protrudes outward in the radial direction of the annular member 60A from the outer peripheral surface of the annular member 60A. The base end side flange portion 58A has an outer diameter smaller than the outer diameter of the rear end portion of the coupling portion body 56A. The base end side flange portion 58A is formed along the entire circumferential surface of the annular member 60A. The outer diameter of the rear end portion of the base end side flange portion 58A gradually decreases toward the rear Y2.

The coupling portion main body 56A, the flange portions 57A, 58A, and the annular members 59A, 60A constituting the coupling member 47A are integrally formed of a relatively soft material such as an elastomer, soft urethane, or rubber.

Further, a waterproof sheet (film) may be disposed on the inner peripheral surface of the coupling portion body 56A.

When the connecting member 47A is formed by foaming using a soft urethane resin or the like, a skin layer having a low foaming ratio is formed on the outer surface of the connecting member 47A. Water leakage can also be prevented by the skin layer.

As shown in fig. 3 and 5, the base end member 48A includes a base end portion main body 64A, a connecting member 65A, an annular member 66A, and a connecting flange portion 67A.

The base end portion body 64A is formed in a tubular shape. As shown in fig. 5, a coupling groove (fitting portion) 69A is formed on the inner peripheral surface of the distal end portion of the proximal end portion main body 64A. The coupling groove 69A is formed along the entire inner peripheral surface of the base end portion body 64A. The coupling groove 69A is fitted to the proximal end side flange portion 58A of the coupling member 47A. The coupling member 47A couples the distal member 46A and the proximal member 48A.

The base end portion main body 64A is preferably formed with the discharge hole 50A in the same manner as the leading end member 46A.

As shown in fig. 3, the coupling member 65A is fixed to the rear end portion of the proximal end portion body 64A. The ring member 66A is fixed to an outer surface 65aA of the left side X2 of the coupling member 65A. An axis (first axis) 70A of the annular member 66A is orthogonal to the outer surface 65aA of the coupling member 65A. The flow path in the annular member 66A communicates with the conduit of the base end portion body 64A via the internal space of the connecting member 65A.

The coupling flange 67A is provided on the outer peripheral surface of the left end of the annular member 66A. The coupling flange 67A projects radially outward from the outer peripheral surface of the annular member 66A. The coupling flange portion 67A is formed along the entire outer peripheral surface of the annular member 66A.

The base end portion main body 64A, the connection member 65A, the annular member 66A, and the connection flange portion 67A constituting the base end member 48A are formed of the same material as the tip end member 46A.

Thus, the coupling member 47A is more flexible and easily deformed than the distal member 46A and the proximal member 48A. In the present embodiment, the first shower arm 43A is bent into an L-shape at an obtuse angle.

As shown in fig. 1, the second shower arm 43B includes a head member 46B, a coupling member 47B, and a base member 48B, which are configured to be plane-symmetrical with the head member 46A, the coupling member 47A, and the base member 48A of the first shower arm 43A.

The distance between the base members 48A, 48B of the shower arms 43A, 43B is preferably about the shoulder width of the user.

The main body 42 includes a frame 76 and a support portion 77.

The frame 76 is formed in a U-shape from a pipe material such as aluminum or stainless steel. More specifically, the frame 76 includes a pair of support pieces 79 arranged in the left-right direction X at intervals, and a coupling piece 80 that couples lower end portions of the pair of support pieces 79 to each other.

The pair of support pieces 79 extend in the vertical direction Z. The connecting piece 80 extends in the left-right direction X at the lower end portions of the pair of support pieces 79.

The upper ends of the pair of support pieces 79 are fixed to the support portion 77.

As shown in fig. 2, the pair of support pieces 79 contact the rear surface of the connecting piece 28. The pair of support pieces 79 are covered with the coupling metal fitting 82 from the rear Y2. A recess 82a for accommodating the pair of support pieces 79 is formed in the front surface of the coupling metal fitting 82. The pair of support pieces 79 are attached to the backrest portion 14 of the chair 11 by bolts 83 that are fitted with the connection pieces 28 of the frame 26 via the connection fittings 82.

On the other hand, by releasing the engagement of the coupling piece 28 and the bolt 83, the pair of support pieces 79 can be detached from the backrest portion 14. Thus, the main body 42 is detachable with respect to the backrest portion 14 and is movable in the vertical direction Z with respect to the backrest portion 14.

The main body 42 of the shower device 41 may be fixed to the backrest 14 of the chair 11 in a non-detachable state.

As shown in fig. 3, the flow path 77a formed in the support portion 77 is open at the right end portion of the support portion 77. The axis of the flow path 77a near the opening coincides with the axis 70A of the annular member 66A of the first shower arm 43A.

In the front view of the shower system 1 shown in fig. 12, the axis 70A, which is the axis of the flow path 77a, extends in the left-right direction X. More specifically, the axis 70A is inclined so as to gradually go to the right side X1 as going upward. The axis 70A and the axis 70B of the second shower arm 43B are inclined in opposite directions to each other with respect to the vertical direction Z so as to be separated from each other with the axis directed upward. In other words, the axes 70A, 70B are inclined in opposite directions to each other with respect to the reference line L3 along the up-down direction Z. For example, reference line L3 is angled upward from axis 70A by an angle θ A of about 60.

In the side view of the shower system 1 shown in fig. 11, the axes 70A, 70B extend in the up-down direction Z. In addition, in the side view of the shower system 1, the axis 70A may be inclined so as to gradually face the front Y1 as it faces upward.

As shown in fig. 3, a main body groove 86A is formed in the inner peripheral surface of the flow path 77a in the vicinity of the opening in the support portion 77. The body groove 86A is formed along the entire inner peripheral surface of the flow path 77 a. The coupling flange 67A of the first shower arm 43A is fitted to the main body groove 86A.

The coupling flange portion 67A rotates about the axis 70A in the body groove 86A, whereby the first shower arm 43A is supported by the support portion 77 so as to be rotatable about the axis 70A. Similarly, the second shower arm 43B is supported on the support portion 77 so as to be rotatable about the axis 70B.

Fig. 7 is a schematic view of a portion connecting the support portion 77 and the first shower arm 43A around the axis being developed linearly. The outer surface 87A near the opening in the support portion 77 faces the outer surface 65aA of the coupling member 65A in the first shower arm 43A.

When the positional relationship of the coupling member 65A with respect to the support portion 77 shown in fig. 7 is established, the first shower arm 43A is in the use state (specific state) P1A as shown in fig. 1. Starting from the time when the first shower arm 43A is in the use state P1A, in fig. 7, the movement of the first shower arm 43A in the direction D1 with respect to the support portion 77 means: as shown in fig. 1, first shower arm 43A rotates in direction D3 about axis 70A with respect to support 77. At this time, the front end member 46A of the first shower arm 43A is lowered, and the first shower arm 43A is in the retracted state P0A shown in fig. 8 and 9. Fig. 9 is a view (front view) of the shower system 1 in which the shower arms 43A and 43B are in the retracted states P0A and P0B, as viewed from the front-rear direction Y.

For example, the rotation angle of the first shower arm 43A about the axis 70A from the use state P1A to the retreat state P0A is 70 °.

On the other hand, when the front end member 46A of the first shower arm 43A is in the use state P1A, in fig. 7, the movement of the first shower arm 43A in the direction D2 with respect to the support portion 77 means: as shown in fig. 1, first shower arm 43A rotates in direction D4 about axis 70A with respect to support 77. At this time, the front end member 46A of the first shower arm 43A rises to become the lifted state P2A shown in fig. 10.

Likewise, when the front end member 46B descends from the use state (specific state) P1B shown in fig. 1, the second shower arm 43B becomes the retracted state P0B shown in fig. 8 and 9. When the front end member 46B rises from the use state P1B shown in fig. 1, it becomes an lifted state P2B shown in fig. 10.

In this way, the base end members 48A, 48B of the shower arms 43A, 43B are rotatably supported by the main body 42 so as to sandwich the main body 42 in the left-right direction X. The base end member 48A of the first shower arm 43A is supported by the right end of the body 42 so as to be rotatable about the axis 70A. Similarly, the base end member 48B of the second shower arm 43B is rotatably supported about the axis 70B at the left end of the main body 42.

Hereinafter, a connection portion between the support portion 77 and the first shower arm 43A will be described in detail.

As shown in fig. 7, a pair of projections 90A, 91A projecting from the outer surface 87A are provided on the outer surface 87A of the support portion 77. The projection 90A is disposed on the direction D1 side of the outer surface 87A, and the projection 91A is disposed on the direction D2 side of the outer surface 87A. Fig. 7 shows a developed shape of the support portion 77 about the axis 70A, and therefore, actually, the projections 90A and 91A are arranged on the outer surface 87A of the support portion 77 at intervals about the axis 70A.

Recesses 93A and 94A are formed in outer surface 87A of support portion 77. A recess 93A is formed on an end portion near the projection 90A in the outer surface 87A between the projection 90A and the projection 91A. A recess 94A is formed on the intermediate portion of the projection 90A and the projection 91A in the outer surface 87A.

Preferably, a plate spring 96A is fixed to a portion of the outer surface 87A adjacent to the recess 94A on the direction D2 side. Plate spring 96A is disposed on the direction D2 side of recess 94A.

The end of the plate spring 96A on the direction D2 side is fixed to the outer surface 87A of the support portion 77. On the other hand, the end portion of the plate spring 96A on the direction D1 side is separated from the outer surface 87A in a natural state where no external force acts on the plate spring 96A. When the end portion on the direction D1 side of the plate spring 96A is urged toward the outer surface 87A, the plate spring 96A is elastically deformed, and the end portion on the direction D1 side of the plate spring 96A is brought into contact with the outer surface 87A as indicated by a line L1 indicated by a two-dot chain line in fig. 7. When the biasing force is released, the plate spring 96A elastically returns to its original shape.

A projection 98A is formed on an outer surface 65aA of the coupling member 65A of the first shower arm 43A. Further, the protrusion 98A and the protrusion 91A of the support portion 77 constitute a regulating portion 95A, and the regulating portion 95A regulates the rise of the front end member 46A of the first shower arm 43A in the lifted state P2A.

The projection 98A is disposed between the pair of projections 90A, 91A of the support portion 77. When first shower arm 43A moves in direction D1 with respect to support portion 77, projection 98A is latched to projection 90A, and first shower arm 43A cannot move further in direction D1. On the other hand, when the first shower arm 43A moves in the direction D2 with respect to the support portion 77, the projection 98A is locked to the projection 91A, and the first shower arm 43A cannot move further in the direction D2.

An engaging portion 100A is fixed to a distal end of the projection 98A via a biasing portion 99A such as a spring.

For example, the locking portion 100A is formed in a spherical shape. The locking portions 100A can be locked to the pair of concave portions 93A, 94A of the support portion 77, respectively. On the other hand, even if the locking portion 100A comes into contact with the outer surface 87A of the support portion 77, it can smoothly (without resistance) move in the direction D1 and the direction D2 with respect to the outer surface 87A.

The urging portion 99A urges the locking portion 100A toward the outer surface 87A of the support portion 77 with respect to the projection 98A.

In the state shown in fig. 7, the locking portion 100A is locked to the recess 94A of the support portion 77. At this time, the first shower arm 43A is in the use state P1A.

Therefore, in order to raise or lower the front end member 46A of the first shower arm 43A in the use state P1A, the urging portion 99A needs to be pushed back toward the projection 98A against the urging force of the urging portion 99A to be retracted. That is, in order to rotate the first shower arm 43A in the use state P1A about the axis 70A, a force for retracting the biasing portion 99A is required, and the use state P1A of the first shower arm 43A is positioned by the recess 94A of the support portion 77.

Further, since the plate spring 96A is provided, in order to raise the front end member 46A of the first shower arm 43A in the use state P1A, the end portion of the plate spring 96A on the direction D1 side needs to be deformed toward the outer surface 87A. The shower apparatus 41 is provided with a plate spring 96A so that the first shower arm 43A in the use state P1A does not become the lifted state P2A without the intention of the user.

When locking portion 100A exceeds recess 94A and leaf spring 96A on the side of direction D2, it is not necessary to deform biasing portion 99A or leaf spring 96A in order to move first shower arm 43A in direction D2. That is, the first shower arm 43A can be easily rotated about the axis 70A.

Fig. 11 and 12 show a side view and a front view of the shower system 1 when the shower arms 43A and 43B are in the use states P1A and P1B, respectively. The shower arms 43A and 43B of the shower system 1 are used when the user sits on the seat 13 of the chair 11 and enters the use states P1A and P1B. The front end members 46A, 46B of the shower arms 43A, 43B in the use states P1A, P1B are higher in position than the front end members 46A, 46B of the retracted states P0A, P0B shown in fig. 8 and 9.

In the front view shown in fig. 12, when the shower arms 43A, 43B are in the use states P1A, P1B, the shower arms 43A, 43B are arranged to extend in the up-down direction Z, respectively. In other words, as shown in fig. 11 and 12, the shower arms 43A and 43B in the use states P1A and P1B are disposed on the reference surfaces SA and SB perpendicular to the left-right direction X, respectively.

As shown in fig. 11, the shower arms 43A and 43B in the use states P1A and P1B are arranged to extend toward the front Y1 with respect to the backrest 14 of the chair 11. The shower arms 43A and 43B in the use states P1A and P1B extend from the main body 42 toward the front Y1, and further extend downward from the front end extending toward the front Y1. The drain holes 50A, 50B of the shower arms 43A, 43B are formed as: when the shower arms 43A and 43B are in the use states P1A and P1B, the water is discharged in an inclined direction between the rear direction Y2 and the lower side.

In the use states P1A and P1B, the shower arms 43A and 43B may be arranged such that at least the portion where the discharge holes 50A and 50B are formed extends forward Y1 with respect to the backrest portion 14.

The first shower arm 43A extends toward the front end member 46A with respect to the axis 70A, and therefore the first shower arm 43A rotates in a direction in which the axis 70A descends toward the front end member 46A due to its own weight (gravity acting on itself).

The first shower arm 43A in the use state P1A is prevented from rotating in this manner by the recess 94A in which the locking portion 100A is locked to the support portion 77 and by the elastic force of the biasing portion 99A.

On the other hand, as shown in fig. 8 and 9, the shower arms 43A and 43B in the retracted states P0A and P0B are in the state when the user does not use the shower arms 43A and 43B. At this time, the front end members 46A and 46B of the shower arms 43A and 43B are lowered compared with the front end members 46A and 46B in the use states P1A and P1B of the shower arms 43A and 43B shown in fig. 11 and 12.

As shown in fig. 9, the shower arms 43A and 43B in the retracted states P0A and P0B are arranged to be gradually separated in the left-right direction X as they go downward. The shower arms 43A and 43B are in a figure-eight shape (inverted V shape) as a whole.

More specifically, the first shower arm 43A is inclined so as to gradually move to the right side X1 as it moves downward. On the other hand, the second shower arm 43B is inclined so as to gradually go to the left side X2 as it goes downward.

As described above, the axes 70A, 70B are inclined with respect to the vertical direction Z, and therefore, when the shower arms 43A, 43B are changed from the use states P1A, P1B to the retracted states P0A, P0B, the shower arms 43A, 43B are gradually separated from each other as they go downward.

In the retracted states P0A and P0B, the distance between the front end members 46A and 46B of the shower arms 43A and 43B is longer than the length in the lateral direction X of the pair of armrests 15 of the chair 11 as a whole. Further, the distance between the front end members 46A, 46B of the shower arms 43A, 43B in the retracted states P0A, P0B is longer than the distance between the front end members 46A, 46B of the shower arms 43A, 43B in the use states P1A, P1B.

In the side view shown in fig. 8, the front end members 46A and 46B of the shower arms 43A and 43B are disposed below the base end members 48A and 48B, respectively. When the shower arms 43A, 43B are in the retracted states P0A, P0B, the discharge holes 50A, 50B of the shower arms 43A, 43B face the rear Y2.

When the shower arms 43A, 43B are in the retracted states P0A, P0B, the projection 98A and the locking portion 100A are arranged at the positions indicated by the line L5 indicated by the two-dot chain line in fig. 7. The locking portion 100A is locked to the recess 93A of the support portion 77, and the protrusion 98A is locked to the protrusion 90A of the support portion 77 from the direction D2 side. Therefore, the first shower arm 43A cannot move further in the direction D1 with respect to the support portion 77, and the front end members 46A and 46B of the shower arms 43A and 43B cannot further descend.

As shown in fig. 10, the lifted states P2A and P2B are states in which the front end members 46A and 46B of the shower arms 43A and 43B are moved (lifted) upward after the user uses the shower arms P1A and P1B. In the shower arms 43A and 43B, the front end members 46A and 46B are located above the use states P1A and P1B in the lifted states P2A and P2B.

At this time, the projection 98A and the locking portion 100A are arranged at positions indicated by a line L6 indicated by a two-dot chain line in fig. 7. The projection 98A is locked to the projection 91A of the support portion 77 from the direction D1 side. Therefore, the first shower arm 43A cannot be moved further in the direction D2 with respect to the support portion 77, and the front end members 46A, 46B of the shower arms 43A, 43B cannot be raised further.

Further, the front end member 46A of the first shower arm 43A in the lifted state P2A is lowered by its own weight to the position of the front end member 46A of the first shower arm 43A in the use state P1A.

A spring may be provided to overcome the self weight of the first shower arm 43A so that the first shower arm 43A can be rotated about the axis 70A with little external force applied between the raised state P2A and the use state P1A. The spring biases the first shower arm 43A about the axis 70A to raise the front member 46A of the first shower arm 43A.

As shown in fig. 1, the connection portion 44 is a connector to which the hose 103 and the like are detachably connected, for example. The connecting portion 44 is fixed to the rear surface of the support portion 77 of the main body 42. Water is supplied from the outside to the connection portion 44 via the hose 103. The water supplied to the connection portion 44 is supplied to the shower arms 43A and 43B through a flow path 77a of a two-branch support portion 77, not shown.

Next, the operation of the shower system 1 configured as described above will be described.

The chair 11 is preliminarily folded, and the shower device 41 is mounted on the chair 11. The shower arms 43A and 43B are in the retracted states P0A and P0B. The shower arms 43A, 43B in the retracted states P0A, P0B are, in a front view, configured to: since the base end members 48A and 48B are gradually separated from each other in the left-right direction X as they go downward, the shower arms 43A and 43B are easily kept away from the pair of armrests 15 of the chair 11 on the outer sides in the left-right direction X.

As shown in fig. 1, the user puts the chair 11 in an unfolded state, and sets the shower system 1 on a floor B1 of a bathroom B or the like. At this time, the hose 103 is connected to a faucet, not shown, and the hose 103 is connected to the connection portion 44 of the shower device 41. The temperature of the water flowing out of the faucet is set to a desired temperature, for example, about 35 c to 40 c, and the faucet is turned on.

The water flowing out of the faucet is initially at ambient temperature of about 15 c to 25 c. The water flowing out of the faucet is supplied to the shower arms 43A and 43B through the hose 103, the connection portion 44, and the flow path 77a of the support portion 77, and is discharged to the outside through the discharge holes 50A and 50B. At this time, since the discharge holes 50A, 50B of the shower arms 43A, 43B face the rear direction Y2, it is possible to suppress the water at the normal temperature from falling on the user.

The user sits on the chair 11 in front of the backrest portion 14 at Y1. When a certain time has elapsed, the temperature of the water discharged from the discharge holes 50A, 50B becomes a desired temperature.

As shown in fig. 13, the user P raises the front end parts 46A, 46B of the shower arms 43A, 43B, thereby bringing the shower arms 43A, 43B into the use states P1A, P1B. When the coupling members 47A, 47B of the shower arms 43A, 43B are soft, the user P lifts the base members 48A, 48B of the shower arms 43A, 43B.

The shower arms 43A and 43B in the use states P1A and P1B extend in the vertical direction Z in front view, respectively, and the distance between the front end members 46A and 46B of the shower arms 43A and 43B in the use states P1A and P1B is shorter than the distance between the front end members 46A and 46B of the shower arms 43A and 43B in the retracted states P0A and P0B. Therefore, the front end members 46A, 46B of the shower arms 43A, 43B are closer to the center of the user P in the left-right direction X than in the retracted states P0A, P0B.

The front end members 46A, 46B of the shower arms 43A, 43B separated from each other in the left-right direction X in the retracted states P0A, P0B are close to the length of the user P on the left and right of the shoulder width in the use states P1A, P1B, and therefore, the shower arms 43A, 43B are less likely to interfere with the pair of armrests 15 of the chair 11, the body of the user P, and the like in the process of changing from the retracted states P0A, P0B to the use states P1A, P1B.

Engaging portion 100A, which is disposed at a position indicated by line L5 in fig. 7 and engaged with recessed portion 93A of support portion 77, moves in direction D2 and is engaged with recessed portion 94A of support portion 77.

As shown in fig. 13, the user P takes a shower using the water W discharged from the discharge holes 50A, 50B of the shower arms 43A, 43B.

The user P may set the shower arms 43A and 43B to the retracted states P0A and P0B to wash his or her body. At this time, since the shower arms 43A and 43B are in the retracted states P0A and P0B, the shower arms 43A and 43B are unlikely to hinder the body washing operation.

When the user P finishes showering, the shower arms 43A and 43B are set to the retracted states P0A and P0B. The faucet in bathroom B was turned off.

If the user P who takes a shower while putting the shower arms 43A and 43B into the use states P1A and P1B is about to promptly leave the shower system 1 due to an emergency, the following procedure is performed.

The user P lifts (lifts) the shower arms 43A and 43B in the use states P1A and P1B, respectively, with a hand or the like. In fig. 7, engaging portion 100A engaged with recessed portion 94A of support portion 77 moves in direction D2, and leaf spring 96A elastically deforms as indicated by line L1 and passes over leaf spring 96A.

The locking portion 100A is arranged at a position shown by a line L6 in fig. 7, and the projection 98A of the first shower arm 43A is locked to the projection 91A of the support portion 77 from the direction D1 side, so that the front end members 46A and 46B of the shower arms 43A and 43B are not further raised.

Since the seat 13 of the chair 11 and the front end parts 46A, 46B of the shower arms 43A, 43B are widened in the up-down direction Z, the user P can stand up from the chair 11 and be detached from the shower system 1 with little interference with the shower arms 43A, 43B. When the front end parts 46A, 46B of the shower arms 43A, 43B in the use states P1A, P1B are raised, since the shower arms 43A, 43B are not fixed, when the body of the user P comes into contact with the shower arms 43A, 43B, the front end parts 46A, 46B of the shower arms 43A, 43B are raised with little resistance.

When the user P releases his or her hand from the shower arms 43A, 43B, the front end members 46A, 46B of the shower arms 43A, 43B are lowered to the positions of the front end members 46A, 46B of the shower arms 43A, 43B in the use states P1A, P1B, respectively, while deforming the leaf springs 96A, 96B by the weight of the shower arms 43A, 43B. At this time, the locking portion 100A is locked to the recess 94A of the support portion 77.

When the user P is detached from the shower system 1, the coupling members 47A and 47B of the shower arms 43A and 43B may be deformed to bend the front end members 46A and 46B in a desired direction.

For example, the user P leaves the right side X1 of the chair 11 after deforming the coupling member 47A of the first shower arm 43A to fold back the front end member 46A to the rear Y2, for example. At this time, since the coupling member 47A is deformed, excessive force does not act on the base end member 48A of the first shower arm 43A, and the first shower arm 43A can be prevented from being damaged.

As described above, even when an emergency occurs, the user P can easily detach from the shower system 1.

The user who operates the shower system 1 or the faucet is not limited to the user who uses the shower system 1 (hereinafter, referred to as an actual user) who actually takes a shower, and may be a caregiver who uses the shower system 1 as an assistant to the actual user.

That is, when it is difficult for the actual user to operate the shower system 1 or the like, the caregiver performs the operation of the shower system 1 or the like.

As described above, according to the shower apparatus 41 of the present embodiment, the user P sits on the chair 11 and takes a shower by receiving water supplied from the connection portion 44 and discharged from the discharge holes 50A and 50B of the shower arms 43A and 43B.

On the other hand, when the shower arms 43A and 43B are not used, the shower arms 43A and 43B are set to the retracted states P0A and P0B. At this time, since the shower arms 43A and 43B are arranged so as to be gradually separated from each other from the base end members 48A and 48B toward the lower side in the front view, the shower arms 43A and 43B are easily kept away from the pair of armrests 15 of the chair 11, the user P seated on the chair, and the like on the outer sides in the left-right direction X. Therefore, when the shower arms 43A and 43B are in the retracted states P0A and P0B, the shower arms 43A and 43B can be prevented from interfering with the pair of armrests 15 of the chair 11, the user P sitting on the chair 11, and the like.

In the use states P1A, P1B, the shower arms 43A, 43B extend in the up-down direction Z, respectively, in front view. Thus, when the shower arms 43A and 43B are in the use states P1A and P1B, the user can take a shower with the water W more effectively at the center in the left-right direction X of the user P than when the shower arms 43A and 43B are in the retracted states P0A and P0B.

The axes 70A, 70B are inclined in opposite directions to each other with respect to the up-down direction Z so as to be separated from each other as facing upward in a front view. By such a simple configuration that the axes 70A, 70B are inclined, the shower arms 43A, 43B can be arranged to be gradually separated from each other as going downward in the retracted states P0A, P0B in front view, and the shower arms 43A, 43B can be arranged to extend in the vertical direction Z in the use states P1A, P1B, respectively.

Further, according to the shower system 1 of the present embodiment, the shower system 1 can be configured using the shower device 41 in which the shower arms 43A and 43B are prevented from interfering with the pair of armrests 15 of the chair 11, the user P sitting on the chair 11, and the like by the shower arms 43A and 43B when the shower arms 43A and 43B are brought into the retracted states P0A and P0B.

While one embodiment of the present invention has been described above in detail with reference to the drawings, the specific configuration is not limited to the embodiment, and modifications, combinations, deletions, and the like of the configuration are included within the scope of the spirit of the present invention.

For example, in the above embodiment, when the shower arms 43A, 43B are in the use states P1A, P1B, the shower arms 43A, 43B may be arranged so as to be gradually separated from each other as going downward in the front view. In this case, the axes 70A, 70B may also be arranged parallel to the horizontal planes, respectively.

The main body 42 may be attached to a support portion such as a pillar provided separately from the chair 11 in the bathroom B. Bathroom B can be a whole bathroom or a bathroom obtained by using a traditional construction method.
