Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a shower hook which can be easily attached without damaging the wall surface of a bathroom.

[0002]

2. Description of the Related Art Conventionally, shower hooks are often attached only to a low position in a bathroom such as an apartment. For this reason, when washing hair, it is inconvenient to sit down and take a cramped posture, or to hold the shower head with one hand and wash the hair with the other hand.

In order to eliminate such inconvenience, shower hooks are commercially available. These can be roughly classified into the following three types depending on the method of attaching them to the wall surface of the bathroom. The three types are those that are attached with screws, those that are adhered with an adhesive, and those that adhere with an adhesive tape.

The screw mounting method cannot be used in bathrooms with tile walls. Even when the wall surface is a resin-based plywood, the shower hook often comes off from the wall surface while it is in use, because sufficient strength and durability cannot be obtained.

In the method using an adhesive, sufficient strength and durability cannot be obtained unless an adhesive that is compatible with both the wall material and the shower hook material is carefully selected. Furthermore, the fact that it is exposed to moisture makes adhesion difficult. In addition to these, in the case of a resin-based plywood wall surface, the wall surface is slightly distorted when the shower head is attached and detached from the shower hook. At this time, the force is concentrated on the adhesive surface, which is one of the causes of impairing durability.

In the method using the adhesive tape, the limitation on the material as in the case of the adhesive is considerably reduced.
However, the strength is obviously inferior when compared with, for example, an epoxy adhesive. In order to compensate for this, there have been some measures to increase the area of the adhesive surface, but it cannot be said to be sufficient.

[0007] In Japanese Utility Model Laid-Open No. 2-144066, a shower head holder that can change the angle of the shower head is shown, but a known shower hook is required to attach this holder, and this shower hook is required. I was faced with the same difficulties as above when I attached the to the wall of the bathroom.

Japanese Unexamined Patent Publication (Kokai) No. 61-204431 discloses a shower device in which the height of the shower head can be changed. However, when the slide rod is attached to the wall of the bathroom, the same difficulties as described above are encountered. It was

Japanese Utility Model Laid-Open No. 5-61259 discloses a shower head holding device for changing the height of the shower head by attaching it to a shower hook installed at a high position in the bathroom. However, there are many cases where the shower hook is not installed at a high position in the bathroom. In such a case, the shower hook had to be attached to the wall surface of the bathroom, and the same difficulties as described above were encountered.

Japanese Patent Laid-Open No. 5-112979 discloses a shower holder for a wall rod. However, when the wall rod was attached to the wall surface of the bathroom, the same difficulties as described above were encountered. The same applies to DE-U-7800834. Here, the wall rod is the same as the slide rod in JP-A-61-204431.

[0011]

As described above, it is very difficult to provide the conventional shower hook with sufficient strength and durability when the general non-specialist performs the installation work. In addition, it is inconvenient for people living in rental houses such as apartments, because it is necessary to make screw holes on the wall surface of the bathroom and to attach an adhesive.

[0012]

The above-mentioned problems can be solved by the shower hook described in each claim.

[0013]

First, the function of the support rod of claim 1 will be described. In claim 1, the elastic body acts so as to push the rod in the axial direction of the rod. The rod has the function of transmitting the restoring force of the elastic body from one end of the rod to the other end. Due to the combined action of the elastic body and the rod, the action of the support rod occurs in which the length shrinks when pushed from both ends and tries to return to the original length.

Next, the operation of the stretchable support rod of claim 8 will be described. The axis of symmetry of the cylindrical knife 3a is called the axis of rotation. The direction along the axis of symmetry of the cylindrical knife 3a is called the axial direction. The direction perpendicular to the axial direction is called the radial direction. The coil spring 7 is fixed to the cylindrical knife 3a so as to prevent rotational movement around the rotation axis and parallel movement in the axial direction.

The guide element is not axially translatable with respect to the coil spring 7, but is capable of rotational movement about its axis of rotation. The guide element and the cylindrical male 3b are fixed.

When the cylindrical male 3b rotates about the rotational axis with respect to the cylindrical female 3a, the guide element is moved by the coil spring 7.
You will be guided along the spiral. As a result, the cylindrical male 3b moves in parallel to the cylindrical female 3a in the axial direction.

An external force causes the cylindrical male 3b to move the cylindrical female 3b.
When translated in the axial direction with respect to a, the length of the coil spring 7 changes from its natural length. At this time, due to the restoring force of the coil spring 7, the cylindrical male 3b tries to return to the original position even if it moves in parallel to the cylindrical female 3a in the axial direction.

With one end of the stretchable support bar being held by the floor and the other end being held by the ceiling, the cylindrical male 3
Consider the case where b is rotated about the rotation axis with respect to the cylindrical knife 3a. However, the rotation direction is the direction in which the stretchable support rod extends. In this way, the coil spring 7 is contracted, and the elastic support rod presses the floor and the ceiling.

Next, the operation of the stretchable support rod according to claim 15 will be described. The axis of symmetry of the cylindrical knife 3a is called the axis of rotation. The direction along the axis of symmetry of the cylindrical knife 3a is called the axial direction. The direction perpendicular to the axial direction is called the radial direction. One end of the coil spring 7 is fixed to the cylindrical knife 3a by a pin 6a. For this reason, the coil spring 7 is
It is not possible to make rotational movement about the axis of rotation and translation in the axial direction.

The pin 6b cannot move in parallel to the coil spring 7 in the axial direction, but can rotate about the rotation axis. The pin 6b and the cylindrical male 3b are fixed.

When the cylindrical male 3b rotates about the rotational axis with respect to the cylindrical female 3a, the pin 6b is moved by the coil spring 7.
You will be guided along the spiral. As a result, the cylindrical male 3b moves in parallel to the cylindrical female 3a in the axial direction.

An external force causes the cylindrical male 3b to move the cylindrical female 3b.
When translated in the axial direction with respect to a, the length of the coil spring 7 changes from its natural length. At this time, due to the restoring force of the coil spring 7, the cylindrical male 3b tries to return to the original position even if it moves in parallel to the cylindrical female 3a in the axial direction.

With one end of the stretchable support bar being held by the floor and the other end being held by the ceiling, the cylindrical male 3
b is rotated about the axis of rotation with respect to the cylindrical knife 3a. However, the rotation direction is the direction in which the stretchable support rod extends. In this way, the coil spring 7 is contracted by the action of the pins 6a and 6b, and the elastic support rod presses the floor and the ceiling.

When the stretchable support rod is upright and pushes the floor and the ceiling, the action of the friction between the upper cap 1a and the ceiling and the friction between the lower cap 1b and the floor causes the stretchable support rod to fall. Prevent the.

In the second aspect, the shower head holding portion 2 is fixed to the mounting element. The mounting element is fastened to the support rod by sandwiching the support rod from at least two directions by the restoring force of the elastic body. Claim 2 in this state
The shower head holding part 2 is fixed to the support rod as in the first aspect. When the support bar pushes the floor and the ceiling to stand upright, the shower head holding unit 2 is held at a constant height above the floor.

When the mounting element is opened by an external force, the mounting element and the support bar are separated.

In the third aspect of the present invention, the shower head holding portion 2 is connected to the support rod by the guide element having a C-shaped cross section. Therefore, in the state where the support bar pushes the floor and the ceiling to stand upright, the shower head holding portion 2 is held at a constant height above the floor.

In the present invention, the shower head holder 2 is fixed to the magnet. The magnet is magnetically attached to the support rod. Therefore, in the state where the support bar pushes the floor and the ceiling to stand upright, the shower head holding portion 2 is held at a constant height above the floor. By applying a force greater than a certain amount, the magnet is separated from the support rod.

In the present invention, the shower head holding portion 2 is connected to the support rod by a guide element having a tubular structure. Therefore, in the state where the support bar pushes the floor and the ceiling to stand upright, the shower head holding portion 2 is held at a constant height above the floor.

In the sixth aspect, the friction between the guide element and the support rod is small when the adjusting screw 15 is loosened. Therefore, in this state, the guide element can move along the support rod.

With the adjusting screw 15 tightened, the guide element is fixed to the support rod. Therefore, when the support rod pushes the floor and the ceiling and stands upright, if the adjusting screw 15 is tightened, the shower head holder 2 is held at a constant height from the floor.

In the seventh aspect, the pressing body pushes the outer surface of the support rod by the restoring force of the elastic body. In this state, the guide element is fixed to the support rod. Therefore, the shower head holding unit 2 is held at a constant height above the floor in a state where the support rod pushes the floor and the ceiling and stands upright.

By applying an external force to the pressing body, the guide element can move along the supporting bar when the pressing force of the pressing body against the supporting bar is reduced.

In the ninth and sixteenth aspects, the shower head holding portion 2 is fixed to the mounting element. The mounting element is fastened to the elastic support rod by sandwiching the elastic support rod from at least two directions by the restoring force of the elastic body. In this state, the shower head holding portion 2 of claims 9 and 16 is fixed to the stretchable support rod in the same manner as in claims 8 and 15, respectively. In the state where the stretchable support rod pushes the floor and the ceiling to stand upright, the shower head holding portion 2 is held at a constant height above the floor.

When the mounting element is opened by an external force, the mounting element and the elastic support bar are separated.

In the tenth and seventeenth aspects, the shower head holding portion 2 is connected to the stretchable support rod by a guide element having a C-shaped cross section. Therefore, in the state where the stretchable support rod pushes the floor and the ceiling to stand upright, the shower head holding portion 2 is held at a constant height from the floor.

In the eleventh and eighteenth aspects, the shower head holding portion 2 is fixed to the magnet. The magnet is magnetically attached to the elastic support rod. Therefore, in the state where the stretchable support rod pushes the floor and the ceiling to stand upright, the shower head holding portion 2 is held at a constant height from the floor. The magnet is separated from the stretchable support rod by applying a force greater than a certain amount.

In the twelfth and nineteenth aspects, the shower head holding portion 2 is connected to the stretchable support rod by a guide element having a tubular structure. Therefore, in the state where the stretchable support rod pushes the floor and the ceiling to stand upright, the shower head holding portion 2 is held at a constant height from the floor.

In the thirteenth and twentieth aspects, when the adjusting screw 15 is loosened, the friction between the guide element and the elastic support rod is small. Therefore, in this state, the guide element can move along the elastic support rod.

With the adjusting screw 15 tightened, the guide element is fixed to the elastic support rod. Therefore, when the elastic support rod pushes the floor and the ceiling and stands upright, the adjusting screw 15 is tightened so that the shower head holding portion 2 is held at a constant height from the floor.

In the fourteenth and twenty-first aspects, the pressing body pushes the outer surface of the stretchable support rod by the restoring force of the elastic body. In this state, the guide element is fixed to the elastic support rod. Therefore, the shower head holding portion 2 is held at a constant height from the floor in a state where the stretchable support rod pushes the floor and the ceiling and stands upright.

The guide element can be moved along the elastic support rod when the pressure applied by the external force of the elastic support rod is reduced by applying an external force to the elastic support rod.

[0043]

Embodiments of the present invention will now be described in more detail with reference to the drawings. Shower head holder 2
Can be made of hard plastic or metal,
It is important that it is strong, does not corrode when exposed to water, and is hygienic.

The stretchable support rod is preferably made of a strong material such as metal or carbon fiber. If it is made of metal, it must be corrosion resistant, such as stainless steel, or covered with a film such as vinyl chloride to prevent the surface from rusting. When this vinyl chloride film is applied, it is possible to easily create a clean product that is suitable for the bathroom, such as white or a light cream color.

The upper cap 1a, the lower cap 1b, and the cover 4 are easy to manufacture if they are made of a soft material such as vinyl chloride, polyethylene, or rubber and are made slightly smaller than the outer diameters of the cylindrical female 3a and the cylindrical male 3b. Is. Because, when the cylindrical female 3a and the cylindrical male 3b are cut from the raw material, the step of removing burrs on the cut surface can be omitted,
This is because no adhesive is needed.

Please refer to FIG. 3 to FIG. In the second embodiment, the shower head holding portion 2 is screwed to a metallic mounting element. The mounting element can also be made of hard plastic. What is important is that the fastening element 8 is sufficiently long in the axial direction of the elastic support rod and that the shower pad holding part 2 is not located too far from the fastening element 8. By doing so, the tilting torque generated by the weight of water in the shower head, the shower hose, and the inside can be reduced, and it is possible to mount the elastic support rod on the elastic support rod by using a weaker spring. If the spring 12 is too strong, the operability will be significantly deteriorated.

In order to prevent the outer surface of the elastic support rod from being damaged by the fastening element 8, a protective plate made of a soft material such as polyethylene or rubber may be sandwiched between the fastening element 8 and the elastic support rod. is there.

Another important point in the second embodiment is that the corners are rounded as much as possible so as not to injure a person in the event of a drop. Metal fittings to prevent falling may be attached to the opening of the clip.

Referring to FIG. In the third embodiment, a guide element having a tubular structure is connected so as to surround the elastic support rod. When the adjusting screw 15 is loosened, it can be easily moved in the axial direction of the elastic support rod. The movable range is approximately from the upper end to the lower end of the elastic support rod. If the tip of the adjusting screw 15 directly hits the stretchable support rod, the surface of the stretchable support rod will be damaged. Therefore, the stretchable support rod should be pressed through a protective plate made of hard plastic or the like.

Instead of the adjusting screw 15, a push rod and an elastic body may be attached. In this case, the guide element is fixed to the elastic support rod by the push rod pressing the outer surface of the elastic support rod by the restoring force of the elastic body. When the push rod is not pressing the elastic support rod by applying an external force, the guide element can easily move along the elastic support rod.

Referring to FIG. This shows a state in which the second embodiment is actually used. The elastic support rod pushes the ceiling of the bathroom and the floor of the bathroom by the restoring force of the elastic body inside. According to experiments, this force is several kilograms to several tens of kilograms, and it can be installed in many kinds of bathrooms nowadays with sufficient strength and durability.

Referring to FIG. In the fourth embodiment, the shower head holder 2 is magnetically attached to a triangular pole type support rod. The magnet is fixed to the back surface of the shower head holder 2. A strong magnet such as samarium-cobalt is used as the magnet.

By moving the length adjusting screw 21 in and out, the distance between the upper pressing body 22a and the lower pressing body 22b is adjusted. Due to the restoring force of the elastic body 22, the upper pressing body 22a presses the ceiling of the bathroom and the lower pressing body 22b presses the floor of the bathroom. In this way, the support bar is installed upright in the bathroom.

The fourth embodiment has the advantage that the coil spring 7 having a relatively short length is used as the elastic body and that the supporting rod has many flat portions, so that the magnet can be easily attached.

Referring to FIG. The example of the elastic support rod which is one of the components of the present invention is shown. This is known.

Referring to FIG. The example of the support bar which is one of the components of this invention is shown. The spacer 23 is inserted into the cylindrical knife 3a according to the height of the ceiling of the bathroom.
This embodiment has an advantage that the coil spring 7 can be shortened as compared with the one shown in FIG.

Further, in this embodiment, the joint between the cylindrical female and the cylindrical male is arranged so as to be as close to the floor as possible. The advantages of this are as follows. The connection between the support bar and the shower head holding part 2 can be separated.
Alternatively, when the connection is slidable, the height of the shower head can be changed from near the ceiling of the bathroom to near the floor, but the joint between the cylindrical female and the cylindrical male may be an obstacle. If the joint is near the floor or near the ceiling, it will not get in the way too much.

[0058]

As described above, according to the present invention, a shower hook having sufficient strength and durability can be attached very easily without damaging the wall surface of the bathroom or applying an adhesive. .

Further in some embodiments of the invention,
There is also an effect that the height of the shower head holding portion 2 can be practically changed from the vicinity of the ceiling to the height of the floor. This is very convenient.

A mother having an infant, when washing the baby's hair,
He had to hold both the showerhead and the baby's head and wash the baby's hair with one hand. This is because the shower hook hits the baby's face or the like because the conventional shower hook does not have the same height. According to the present invention, since the height of the shower hook can be easily moved to a considerably low position, the hand holding the shower head is released, and such inconvenience is eliminated.

In a family with an elderly person who is physically handicapped, when the elderly person takes a bath, in order to prevent danger, the elderly person should sit on the floor or chair of the bathroom and wash his body. It was Also in this case, since the height of the shower hook was inappropriate, the shower head was held by one hand and the other hand was rubbed. In this way, it was inconvenient for another person to hold the elderly body to prevent danger.

By using the present invention, such inconvenience can be eliminated. The hands holding the shower head are released, so you can support the elderly body with your free hands. Therefore, it is very convenient because another person does not need to support the elderly.

It is convenient for a healthy person to take a shower normally, especially for washing hair or shaving.

There is a known shower hook whose height can be changed as described above (for example, DE-U).
-78000834). However, since the bathroom is a place where construction is difficult as described above, special work was required for the installation work. The same is true for shower bars currently on the market in Japan. As a result, such a shower hook with a variable height becomes an expensive one, and it is hardly popular among people who live in rental houses and housing estates.

By using the present invention, it is possible to provide a shower hook that can be easily attached. Moreover, since the structure is simple, it can be provided at low cost.

As described above, the present invention greatly contributes to the lives of many people, including those who have infants or physically handicapped elderly people and live in rental housing such as apartments and housing complexes.
