Jikkai Sho 57-85069

The shower head, which is fixed to the mounting surface of the bathroom wall by magnetic adsorption, is used in an environment where water droplets adhere to it, and a large water pressure acts when the shower water is discharged, so the fixed state to the mounting surface tends to be unstable. Tend. As a method of stabilizing the fixed state with respect to the mounting surface, it is conceivable to increase the magnetic attraction force generated between the mounting surface and the shower head. However, if the magnetic attraction force is increased, a large force is required at the time of removal, which reduces its convenience.

The present invention has been made in view of such circumstances, and an object of the present invention is to achieve both stabilization of the fixed state of the shower head with respect to the mounting surface and reduction of the force required for the operation of removing the shower head from the mounting surface. There is.

The shower head that solves the above problems is a shower head provided with a suction portion that magnetically attracts to a predetermined mounting surface, and the first suction portion and the second suction portion provided at positions separated from each other as the suction portion. A grip portion that does not magnetically attract the mounting surface is provided between the first suction portion and the second suction portion, and the mounting surface and the grip portion in a state of being mounted on the mounting surface The space or the grip portion is provided with a space for gripping the grip portion by wrapping around the finger.

According to the above configuration, since the first suction portion and the second suction portion are provided at positions separated from each other and a plurality of suction portions are provided, it is easy to secure a high magnetic attraction force. Therefore, even when the shower head is mounted on a wet mounting surface or when water pressure at the time of shower water discharge is applied, the fixed state of the shower head with respect to the mounting surface is stabilized, and misalignment or disengagement can be suppressed.

When removing the shower head from the mounting surface, hold the grip portion provided between the first suction portion and the second suction portion, and suck in order from either one of the first suction portion and the second suction portion. By separating the portions from the mounting surface, the shower head can be removed with a force relatively small with respect to the magnetic attraction force of the first suction portion and the second suction portion. In particular, since the grip portion has a shape that allows the fingers to wrap around and firmly grip the shower head, it is easy to perform an operation of attaching the shower head to the mounting surface and an operation of removing the shower head from the mounting surface.

In the shower head, it is preferable that the magnetic attraction force of the first suction portion and the magnetic attraction force of the second suction portion are different.
According to the above configuration, when the shower head is removed from the mounting surface, the shower head can be easily removed by performing an operation of separating the shower head from the mounting surface in order from the suction portion having the smallest magnetic attraction force.

In the shower head, the mounting surface is attached to at least one of the end portion of the first suction portion opposite to the second suction portion and the end portion of the second suction portion opposite to the first suction portion. It is preferable that a corner portion is provided so as to create a gap between the mounting surface and the mounting surface.

According to the above configuration, when the shower head is removed from the mounting surface, the operation of tilting the shower head can be easily performed by using the corner portion of the end portion of the first suction portion or the second suction portion as a fulcrum. can.

In the shower head, the grip portion is formed so as to project from the mounting surface side when mounted on the mounting surface.
According to the above configuration, the grip portion can be easily gripped even in a state of groping where the position of the shower head attached to the mounting surface cannot be clearly seen, such as when washing away bubbles or the like adhering to the hair when washing the hair. be able to. In addition, it is possible to prevent the fingertip from hitting the mounting surface when gripping the grip portion.

In the shower head, it is preferable that both the first suction portion and the second suction portion are provided in a portion below the center of the shower face in the vertical direction.
A relatively heavy member tends to be arranged around the shower face in the shower head. Therefore, by providing the first suction portion and the second suction portion in the portion below the center of the shower face as in the above configuration, it becomes easy to position the center of gravity of the shower head in the vicinity of the grip portion. By locating the center of gravity of the shower head in the vicinity of the grip portion, it becomes easy to perform an operation of attaching the shower head to the mounting surface and an operation of removing the shower head from the mounting surface.

According to the present invention, it is possible to achieve both stabilization of the fixed state of the shower head with respect to the mounting surface and reduction of the force required for the operation of removing the shower head from the mounting surface.

Hereinafter, an embodiment of the present invention will be described.
As shown in FIGS. 1 and 2, the shower head 10 includes a housing 11 that forms the outside thereof. The housing 11 includes a head portion 13 in which a shower face 12 having a discharge hole for discharging shower water is located, and a grip portion 14 provided under the head portion 13.

As shown in FIGS. 1 and 3, the head portion 13 has a shape that is inclined toward the back side from the upper side to the lower side, and the shower face 12 located on the front side is configured to face diagonally downward. .. The grip portion 14 is formed in an arch shape that extends in the vertical direction and is curved so that the central portion in the vertical direction bulges toward the front side. The head portion 13 and the grip portion 14 are connected so as to form a V-shape in a side view.

As shown in FIGS. 1 and 2, a first accommodating portion 15a and a second accommodating portion 15b that open from the back surface side to the side surface side are formed on the back surface side of the housing 11. The first accommodating portion 15a is located at the connecting portion between the head portion 13 and the grip portion 14, and the second accommodating portion 15b is located at the lower part of the grip portion 14.

As shown in FIGS. 2 and 3, the first accommodating portion 15a accommodates the first adsorbing portion 20 that magnetically attracts to a predetermined mounting surface. The first suction portion 20 includes a first case member 21 having a U-shaped cross section fixed to the first accommodating portion 15a, and a first magnet 22 accommodated in the first case member 21. The suction surface 20a, which is the back surface of the first suction portion 20, is formed in parallel in the vertical direction and protrudes toward the back side from the housing 11.

Further, the housing 11 includes a first lid member 16a that closes the side surface side of the first accommodating portion 15a. The first lid member 16a is fixed to the first accommodating portion 15a in a state where the first suction portion 20 is accommodated by a screw 17a. The first suction portion 20 is fixed in the housing 11 by closing the side surface side of the first accommodating portion 15a with the first lid member 16a.

As shown in FIGS. 2 and 3, the second accommodating portion 15b accommodates the second accommodating portion 30 that magnetically attracts to a predetermined mounting surface. The second suction portion 30 includes a second case member 31 having a U-shaped cross section fixed to the second accommodating portion 15b, and a second magnet 32 accommodated in the second case member 31. The suction surface 30a, which is the back surface of the second suction portion 30, is formed in parallel in the vertical direction and protrudes toward the back side from the housing 11.

Further, the housing 11 includes a second lid member 16b that closes the side surface side of the second accommodating portion 15b. The second lid member 16b is fixed to the second accommodating portion 15b in a state where the second suction portion 30 is accommodated by the screw 17b. The second suction portion 30 is fixed in the housing 11 by closing the side surface side of the second accommodating portion 15b with the second lid member 16b.

As shown in FIG. 3, both the first suction portion 20 and the second suction portion 30 are provided in a portion below the center line L of the shower face 12 in the vertical direction. As a result, the center of gravity of the shower head 10 is positioned in the vicinity of the grip portion 14.

Further, as the second magnet 32, a magnet having a smaller magnetic force than the first magnet 22 is adopted. As a result, the magnetic attraction force of the second suction unit 30 is adjusted to be smaller than that of the first suction unit 20. As the first magnet 22 and the second magnet 32, permanent magnets such as alloy magnets, ferrite magnets, and rare earth magnets can be used.

As shown in FIGS. 1 to 3, a connecting portion 18 connected to the water supply hose is attached to the lower portion of the housing 11.
The configuration of the flow path or the like provided inside the housing 11 is not particularly limited, and a configuration used for a known shower head can be appropriately adopted.

Next, the operation of this embodiment will be described.
As shown in FIG. 4, the shower head 10 is used by being installed in a bathroom or the like having a wall portion 40 that functions as a magnetic material. Examples of the wall portion 40 that functions as a magnetic material include a wall panel containing a steel plate and a wall panel made of enamel.

The shower head 10 is first made by bringing the first suction portion 20 and the second suction portion 30 provided on the back surface side of the housing 11 into contact with the mounting surface 41 at an arbitrary position on the mounting surface 41 of the wall portion 40. It is attached to the mounting surface 41 based on the magnetic attraction force generated between the suction portion 20 and the second suction portion 30 and the mounting surface 41. Specifically, the suction surface 20a of the first suction unit 20, the suction surface 30a of the second suction unit 30, and the mounting surface 41 are fixed to the mounting surface 41 in a state where the surfaces are in contact with each other.

At this time, the shower head 10 is attracted to the mounting surface 41 at two positions separated from each other in the vertical direction (longitudinal direction of the shower head 10), the first suction portion 20 and the second suction portion 30. Therefore, a higher magnetic attraction force can be obtained as compared with a configuration in which the portions to be attracted to the mounting surface 41 are concentrated in one place.

On the other hand, when removing the shower head 10 from the mounting surface 41, hold the grip portion 14 and tilt the shower head 10 upward or downward as shown by arrow A or arrow B to make the first suction portion 20 and the first suction portion 20 and the second. 2 The suction portion 30 is separated from the mounting surface 41 in order from one side. Then, the tilted shower head 10 is pulled toward the front side to separate the other side of the first suction portion 20 and the second suction portion 30 from the mounting surface 41.

Here, as shown in FIG. 3, since the first suction portion 20 is provided so as to project from the housing 11 to the back surface side, the upper end portion (second) of the first suction portion 20 on the suction surface 20a. At the end portion on the opposite side of the suction portion 30, there is a corner portion 23 that creates a gap S1 between the suction portion 30 and the mounting surface 41. Therefore, by using the corner portion 23 as a fulcrum, the shower head 10 can be easily tilted upward (the arrow A side in FIG. 4). The corner portion 23 of the first suction portion 20 is composed of the first case member 21.

Similarly, the second suction portion 30 also has a gap S1 between the second suction portion 30 and the mounting surface 41 at the lower end portion (the end portion opposite to the first suction portion 20) of the suction surface 30a. There is a corner portion 33 to be generated. Therefore, by using the corner portion 33 as a fulcrum, the shower head 10 can be easily tilted downward (arrow B side in FIG. 4). The corner portion 33 of the second suction portion 30 is composed of a second magnet 32.

Further, in the shower head 10 of the present embodiment, the magnetic attraction force of the second suction unit 30 is adjusted to be smaller than that of the first suction unit 20. Therefore, if the shower head 10 is tilted upward (the arrow A side in FIG. 4) so that the second suction portion 30 having a small magnetic attraction force is first separated from the mounting surface 41, the shower head 10 is separated from the mounting surface 41 first. Can be removed.

Further, as shown in FIGS. 3 and 4, the grip portion 14 is formed in a bow shape in which the central portion in the vertical direction is curved so as to bulge toward the front side, so that the grip portion 14 is between the grip portion 14 and the mounting surface 41. Space S2 is formed in. Therefore, even when the grip portion 14 is mounted on the mounting surface 41, the grip portion 14 can be firmly gripped by wrapping a finger around the back side of the grip portion 14 through the space S2. Therefore, when the shower head 10 is attached to the mounting surface 41 and the shower head 10 is removed from the mounting surface 41, the force is easily transmitted to the shower head 10. Further, the hand holding the grip portion 14 is less likely to get in the way, and each of the above operations can be easily performed.

Next, the effect of this embodiment will be described.
(1) The shower head 10 includes a first suction portion 20 and a second suction portion 30 provided at positions separated from each other as suction portions that magnetically attract to the mounting surface 41. A grip portion 14 that does not magnetically attract is provided on the mounting surface 41 between the first suction portion 20 and the second suction portion 30. A space S2 for gripping the grip portion 14 by wrapping a finger around is provided between the mounting surface 41 and the grip portion 14 in a state of being mounted on the mounting surface 41.

According to the above configuration, since the first suction portion and the second suction portion are provided at positions separated from each other and a plurality of suction portions are provided, it is easy to secure a high magnetic attraction force. Therefore, even when the shower head is mounted on a wet mounting surface or when water pressure at the time of shower water discharge is applied, the fixed state of the shower head with respect to the mounting surface is stabilized, and misalignment or disengagement can be suppressed.

On the other hand, when the shower head 10 is removed from the mounting surface 41, the first suction portion 20 and the second suction portion 20 are held by holding the grip portion 14 provided between the first suction portion 20 and the second suction portion 30. The suction portion is separated from the mounting surface 41 in order from any one side of 30. As a result, the shower head 10 can be removed with a relatively small force with respect to the magnetic attraction force of the first suction section 20 and the second suction section 30.

Further, since the grip portion 14 has a shape that allows the fingers to wrap around and firmly grip the shower head 14, it is easy to perform an operation of attaching the shower head 10 to the mounting surface 41 and an operation of removing the shower head 10 from the mounting surface 41. Further, when the shower head 10 is attached to or detached from the attachment surface 41, the situation where the shower head 10 is changed is reduced.

(2) The magnetic attraction force of the second suction unit 30 is adjusted to be smaller than the magnetic attraction force of the first suction unit 20.
According to the above configuration, when the shower head 10 is removed from the mounting surface 41, the shower head 10 is tilted so as to be separated from the mounting surface 41 first from the second suction portion 30 having a small magnetic attraction force. 10 can be easily removed.

(3) At the end of the first suction portion 20 opposite to the second suction portion 30, a corner portion 23 that creates a gap S1 with the mounting surface 41 when mounted on the mounting surface 41 is provided. ing. Further, at the end of the second suction portion 30 opposite to the first suction portion 20, a corner portion 33 that creates a gap S1 with the mounting surface 41 when mounted on the mounting surface 41 is provided. There is.

According to the above configuration, when the shower head 10 is removed from the mounting surface 41, the operation of tilting the shower head 10 with the corner 23 of the first suction portion 20 or the corner 33 of the second suction portion 30 as a fulcrum can be easily performed. It can be carried out.

In particular, in the above embodiment, as shown in FIG. 3, the portion of the housing 11 located above the first suction portion 20 and the portion located below the second suction portion 30 are bent toward the front side. The gap S1 formed between the mounting surface 41 and the mounting surface 41 is large. By ensuring a large gap S1, the operation of tilting the shower head 10 with the corners 23 and 33 as fulcrums can be performed more easily.

(4) The grip portion 14 is formed so as to project from the mounting surface 41 side to the front side when mounted on the mounting surface 41.
According to the above configuration, the grip portion can be easily gripped even in a state of groping where the position of the shower head 10 attached to the mounting surface 41 cannot be clearly seen, as in the case of washing away bubbles or the like adhering to the hair during hair washing. You can hold 14. Further, it is possible to prevent the fingertip from hitting the mounting surface 41 when gripping the grip portion 14.

(5) Both the first suction portion 20 and the second suction portion 30 are provided in a portion below the center line L of the shower face 12.
A relatively heavy member tends to be arranged in the peripheral portion of the shower face 12 in the shower head 10. Therefore, as in the above configuration, the center of gravity of the shower head 10 is positioned in the vicinity of the grip portion 14 by providing the first suction portion 20 and the second suction portion 30 in the portion below the center of the shower face 12. Becomes easier. By locating the center of gravity of the shower head 10 in the vicinity of the grip portion 14, it becomes easy to perform an operation of attaching the shower head 10 to the mounting surface 41 and an operation of removing the shower head 10 from the mounting surface 41.

This embodiment can be modified and implemented as follows. It is also possible to appropriately combine the configurations of the above-described embodiment and the configurations shown in the following modified examples.
As shown in FIG. 5, the grip portion 14 may be provided with a space S2 for gripping the grip portion 14 by wrapping a finger around the back side by forming the grip portion 14 in an annular shape or the like. In this case, it is not necessary to provide the space S2 between the grip portion 14 and the mounting surface 41.

The shape of the grip portion 14 is not limited to a shape that protrudes to the front side as long as a space S2 for gripping the grip portion 14 by wrapping a finger around the back side is secured. For example, the grip portion 14 may be a grip portion 14 extending linearly in the vertical direction.

The configuration for making the magnetic attraction forces of the first adsorption unit 20 and the second adsorption unit 30 different is not limited to the configuration of the above embodiment. For example, the magnetic attraction force may be reduced by making the surface (adsorption surface) of one of the adsorption portions rough.

The magnetic attraction force of the second suction unit 30 may be adjusted to be larger than the magnetic attraction force of the first suction unit 20. In this case, when the shower head 10 is removed from the mounting surface 41, the shower head 10 is tilted so as to be separated from the mounting surface 41 first from the first suction portion 20, thereby achieving the same effect as in (2) above. Is obtained. Further, the magnetic attraction force of the second suction unit 30 and the magnetic attraction force of the first suction unit 20 may be adjusted to be equal to each other.

The configuration for generating the magnetic attraction force between the first suction unit 20 and the second suction part 30 with the mounting surface 41 is not particularly limited. For example, electromagnets may be used as the first magnet 22 and the second magnet 32. Further, a structure for generating a magnetic field such as a magnet may be provided on the mounting surface 41 side, and the first suction part 20 and the second suction part 30 may be made of a magnetic material.

The configuration of the corner portions 23 and 33 that generate the gap S1 between the first suction portion 20 and the second suction portion 30 and the mounting surface 41 is not limited to the above embodiment. For example, as shown in FIG. 6A, a corner portion 23 may be provided on the first magnet 22 by using the first magnet 22 having a trapezoidal shape protruding on the mounting surface 41 side in a cross-sectional view. ..

Further, as shown in FIG. 6B, the housing 11 has a flat portion 24a located on the same surface as the surface of the first magnet 22 with respect to the periphery including at least the upper side of the first accommodating portion 15a. A protruding portion 24 that protrudes to the back side is provided. Then, the corner portion of the protruding portion 24 is used as a corner portion that creates a gap S1 with the mounting surface 41. In this case, the protruding portion 24 also constitutes one configuration of the first suction portion 20.

Further, the corner portions 23 and 33 may have a shape other than a curved shape or the like having a pointed tip (pin angle shape). For example, the corners 23 and 33 may be C-chamfered or R-chamfered.
The first suction portion 20 and the second suction portion 30 may be configured such that the corner portions are provided on only one of them, or both suction portions may be configured such that the corner portions are omitted.

-The arrangement of the first suction unit 20 and the second suction unit 30 may be changed. For example, of the first suction part 20 and the second suction part 30, the first suction part 20 located on the upper side is provided at the same position as the center line L of the shower face 12 or on the upper side of the center line L and is located on the lower side. Only the second suction portion 30 may be provided below the center line L of the shower face 12. Further, the first suction portion 20 and the second suction portion 30 may be provided so as to be arranged in the left-right direction. In this case, it is preferable that the grip portion 14 is provided so as to extend in the left-right direction.

The configurations of the suction surfaces 20a and 30a of the first suction unit 20 and the second suction unit 30 may be changed. For example, it may be a rough surface-like suction surface. In this case, when water droplets are attached to each suction portion or the mounting surface 41, the water droplets enter the recesses on the rough surface, so that the suction surface and the mounting surface 41 come into direct contact with each other without the water droplets. It will be easier to do. As a result, the fixed state of the shower head 10 with respect to the mounting surface 41 is further stabilized.

Further, the first suction portion 20 and the second suction portion 30 may be provided with a coating portion that covers the surface of the magnet. In this case, the suction surface is formed by the covering portion.
Further, the suction surface made of a soft material may be used by using a magnet made of rubber or a rubber covering portion. In this case, it is possible to prevent the mounting surface 41 from being damaged when the shower head 10 is mounted on the mounting surface 41 or when the position of the shower head 10 is changed by sliding on the mounting surface 41.

The configurations of the first suction unit 20 and the second suction unit 30 may be the same, or a part or all of them may be different.
A structure may be configured in which a suction unit is further provided in addition to the first suction unit 20 and the second suction unit 30.

-As shown in FIG. 7, the shower head 10 may be configured to be fixed to the hanger 42 provided on the mounting surface 41. For example, as the connecting portion 18, one having a strength and a shape that can be locked to the hanger 42 is adopted. In this case, the shower head 10 can be fixed to the hanger 42 of the mounting surface 41 even when the wall portion 40 is changed to one that does not function as a magnetic material due to reform or the like.
