Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless waterproof push button switch which is mounted on a wall surface of a bathroom and used as an emergency switch or the like. In particular, it relates to measures for increasing the number of functions of waterproof members.

[0002]

2. Description of the Related Art Conventionally, an emergency switch or the like installed in a bathroom has adopted a waterproof structure to prevent water from entering the inside of a switch case. The general structure of this type of switch is shown in FIG. As shown in this figure, a switch case a is constituted by a front case b and a back cover c. An opening d is formed in the center of the front case b, and an operation button e is provided inside the opening d. For this reason, it is necessary to adopt a waterproof structure at the part where the front case b and the back cover c meet, and at the contact part between the operation button e and the edge of the opening d.

[0003] Specifically, an annular waterproof packing f is interposed at a portion where the front case b and the back cover c are joined. As a waterproof structure of a contact portion between the operation button e and the edge of the opening d, a flange g extending inward (downward) of the case over the entire periphery of the edge of the opening d is formed. The outer periphery of the operation button e is sandwiched between the operation button e and the substrate h accommodated in the case b. As described above, in the conventional waterproof switch, the mating portion between the front case b and the back cover c, the operation button e and the opening d
An individual waterproof structure is adopted for each of the contact portions with the edge portion of the. For this reason, not only has the switch structure become complicated, but also it is necessary to establish a high waterproof performance individually, so that the design of each waterproof portion involves difficulty.

To solve this problem, for example,
Japanese Utility Model Laid-Open No. 62-188834 and Japanese Utility Model Laid-Open No. 6-7029.
2. Description of the Related Art A waterproof structure disclosed in Japanese Unexamined Patent Publication No. 2 (Kokai) No. 2 is known.

In the former publication, a single key rubber having a key projection is provided at a position corresponding to the switch contact, and the periphery of the key rubber is sandwiched between a front case and a back cover. The seal structure between the front case and the back cover is realized. That is, the seal structure at the peripheral portion of the operation button is not required, and the key rubber constituting the operation button can be used as a sealing material between the front case and the back cover. Further, the surface of the key projection is covered with a thin resin plate to constitute a membrane switch.

In the latter publication, an elastic body in which a button portion and a packing portion are integrated is housed in a front case, and the periphery of the elastic body is formed by a front case and a back cover. The seal structure is realized by sandwiching.

[0007]

As an example of this type of switch, there is known a switch provided with an indicator light on the operation surface side. The indicator light is housed inside an opening formed in a part of the front case, and the opening is covered by a transparent or translucent cover plate. As a result, the light of the indicator light passes through the cover plate, and the operator can visually recognize the light to recognize that a wireless signal can be transmitted by a switch operation.

For this reason, a waterproof structure is required even at the location where the indicator light is provided. That is, it is necessary to arrange a packing or the like between the edge of the opening formed in the front case and the cover plate to establish a waterproof function.

As described above, in the switch having the indicator light, since the waterproof structure of the indicator light arranging portion is independently provided, the switch using the waterproof structure disclosed in each of the above publications is used. Even so, the waterproof structure of the indicator light arranging part must be provided separately from this waterproof structure. This not only increases the number of parts for waterproofing, but also because the independent waterproof structure is provided separately at a plurality of locations, the reliability of the waterproof performance of the entire switch may not be sufficiently obtained. was there.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a wireless waterproof push button switch having an indicator light so that light emitted from the indicator light can be visually recognized. It is an object of the present invention to make it possible to establish the waterproof structure of each part of the switch with a single component.

[0011]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a wireless waterproof push button switch provided with an indicator light as a waterproof member.
It has the function of sealing the mating parts of the housing components, the function of preventing water from entering through the light emitting hole, and the function of a switch elastic body. By allowing this light to pass through the member and making this part a light transmission window, the user can visually recognize the light.

-Solution Means- Specifically, a first solution means taken by the present invention is a case in which a plurality of housing components are integrally assembled and partially provided with a light emitting hole; It is assumed that the wireless waterproof push button switch includes a push button provided on the surface of the body and an indicator light housed in the housing at a position facing the light emitting hole. A waterproof member made of an elastic material is accommodated in the housing of the wireless waterproof push button switch. Then, the waterproof member is provided with a housing waterproof portion, a floodlight waterproof portion, and a switch elastic portion. The casing waterproof part seals between the casing constituent members by interposing the joining part between the casing constituent members. The floodlight waterproof section covers the indicator light,
The light emitting hole is closed. The switch elastic portion is configured to apply a pressing force to the push button. Further, at least the light-transmitting waterproof portion of the waterproof member is made transparent or translucent so that light from the indicator lamp can be transmitted.

According to this specific feature, the waterproof member has a function of sealing the mating portion between the housing constituent members, a function of preventing water from entering from the light emitting hole, and a function as a switch elastic body. It is possible to make it. In other words, it is possible to establish a waterproof structure with respect to a plurality of portions of the switch by using one member, and to additionally have a function as a switch elastic body. In addition, this waterproof member,
Since the floodlight waterproof part is transparent or translucent, light from the indicator lamp can be transmitted, and the user can easily recognize this light.

The second solution specifically specifies the internal structure of the switch. That is, in the first solving means, the housing constituent member is a first housing constituent member and a second housing constituent member detachable from the first housing constituent member. The setting change means for changing the setting of the switch operation and the battery are accommodated in the housing, and the setting change operation of the setting changing means and the battery replacement are performed by removing the second housing constituent member from the first housing constituent member. Work can be done.

According to this specific matter, the setting change operation and the battery replacement operation can be performed only by removing the second housing component from the first housing component. Therefore, the setting change operation and the battery replacement operation can be performed by relatively simple operations while maintaining the operation according to the first solving means.

A third solution is to improve the waterproof member in order to improve the ease of use of the switch. That is, in the first or second solution, in the casing waterproof portion of the waterproof member, the exposed portion exposed from the joining portion of the casing component members or the outer surface of the joining portion of the casing component members is located outside the outer surface. A protruding projection is provided.

According to this specific matter, when the user grips the switch, the exposed portion or the protruding portion of the mating portion of the housing components comes into contact with the hand. Since the exposed portion or the protruding portion is made of an elastic material, the familiarity with the hand is good. That is, the switch is less likely to slip off from the hand, and a switch with excellent operability can be provided by effectively using the waterproof member. In particular, in the case where the housing waterproof portion is provided with a protruding portion, the presence of the portion protruding from the housing improves the catching of the finger and further improves the operability.

The fourth means for solving the above problems is the first, second or third solution.
In the above solution, an opening is formed on a surface of the housing at a position facing the switch elastic portion. Further, the push button is constituted by a switch plate fitted into the opening and formed of a hard material.

According to this specific matter, when performing a switch operation, the switch plate is pushed in, and the pushing force acts on the switch elastic portion to turn on the switch. At this time, since the switch plate is formed of a hard material, the friction with the edge of the opening is reduced, and the pushing operation and the returning operation can be performed even if the gap between the inner edge of the opening and the outer edge of the switch plate is small. Well done.

Preventing. Further, since the waterproof member 5 is a translucent body, the light emitted from the indicator lamp 81 is transmitted through the light projecting unit 54 and projected to the outside.

The upper surface of the light projecting portion 54 is formed in an arc shape in cross section which protrudes from the flat portion 21 of the front case 2. Therefore, the light transmitted through the light projecting portion 54 is projected not only in a direction perpendicular to the flat portion 21 of the front case 2 but also in a direction parallel to the flat portion 21. (See the arrow in FIG. 2). That is, the user can view light not only from a direction perpendicular to the plane portion 21 but also from a direction parallel to the plane portion 21, so that good visibility is ensured. ing.

In the case of the present embodiment, the waterproof member 5 and the switch plate 27 are set to the same color (milky white).
Note that these colors may be different from each other. This coloring operation is performed by, for example, a well-known two-color molding technique performed simultaneously with molding, surface coloring after molding, or the like.

-Description of Switch Operation- Next, the operation of the switch 1 configured as described above will be described. When the switch 1 is turned on, the user pushes the switch plate 27 while holding the switch 1. This pushing force acts on the switch elastic portion 55 from the switch plate 27, and the switch contact 51 contacts the substrate 8. As a result, an emergency wireless signal is transmitted from the switch 1, an emergency device (not shown) emits an emergency signal (voice or light), or a notification is sent to a security company.

The light emitted from the indicator lamp 81 is emitted from the light emitting unit 5.
4, the light is transmitted from the light projecting hole 25 to the outside.
The user can easily visually recognize the light emission.

Even when the switch 1 is exposed to water, the outer case seal 53 of the waterproof member 5 exists between the front case 2 and the back cover 4 so that the front case 2 The mating portion of the switch and the back cover 4 is securely sealed, so that water does not enter the inside of the switch from this portion. Further, since the light projecting portion 54 is fitted into the light projecting hole 25 of the front case 2, water does not enter the inside of the switch from this portion. That is, the light projecting unit 54 has both the function of transmitting the light emitted from the indicator lamp 81 and the function of sealing the periphery of the indicator lamp 81.

-Effects of Embodiment- As described above, in the present embodiment, the waterproof member 5 has a function of sealing the mating portion between the front case 2 and the back cover 4, and a function of infiltrating water from the light projecting hole 25. And a function as a switch elastic body. That is, it is possible to establish a waterproof structure with respect to a plurality of portions of the switch 1 with one waterproof member 5 and to have a function as a switch elastic body.
For this reason, the number of parts for waterproofing can be minimized, and the reduction in the number of parts improves the reliability of waterproofing performance, simplifies the internal structure of the switch, simplifies switch assembly work, and reduces manufacturing costs. Can be achieved. In addition, the waterproof member 5 is capable of transmitting light from the indicator light 81, so that the user can easily visually recognize the light, and obtain the above-described effect without impairing the visibility of the indicator light 81. Can be.

By removing the screw 6, the back cover 4 can be easily removed. This back cover 4
In the state in which is removed, the setting change operation of the switch setting nameplate 36, the battery replacement operation, and various maintenance operations can be performed, and the workability of these operations is easy.

Further, in the case of this embodiment, the switch plate 2
If the gap between the bulging portion 27a of the waterproof member 5 and the switch contact 51 attached to the switch elastic portion 55 of the waterproof member 5 and the board 8 are set to be relatively large, The pushing amount when the switch 1 is turned on can be set large. For this reason, a better operational feeling can be obtained as compared with a conventional switch employing a membrane switch.

Further, since the switch plate 27 is formed of a hard material, the pushing force can be easily transmitted to the switch contact 51 even if the portion away from the portion facing the switch contact 51 is pushed. For this reason, a more reliable operation can be performed as compared with the case of using a conventional membrane switch made of a soft material or the case of using the elastic button disclosed in Japanese Utility Model Laid-Open No. 6-70292. The size of the switch plate 27 can be increased. Furthermore, by making the switch plate 27 large, operability is improved and the degree of freedom in designing the switch 1 can be increased.

In addition, when the friction between the switch and the opening edge is large, such as when the elastic button disclosed in Japanese Utility Model Application Laid-Open No. 6-70292 is used, the switch is pushed in. It was necessary to ensure a relatively large gap between the outer edge of the switch and the inner edge of the opening in order to properly perform the subsequent return operation. For this reason, the appearance of the switch is deteriorated. In this embodiment, since the switch plate 27 is formed of a hard material, the friction between the outer edge of the switch plate 27 and the inner edge of the opening 24 when the switch plate 27 slides with respect to the opening 24 when the switch is operated. The resistance is smaller than that using the elastic button, and the gap between the outer edge of the switch plate 27 and the inner edge of the opening 24 can be reduced.
It is possible to ensure the appearance of the switch while ensuring the return operation.

-Other Embodiment- FIG. 5 shows another embodiment. The waterproof member 5 according to this embodiment includes a front case 2
And a back cover 4 and a protruding portion 53d protruding outside of the outer surface of the mating portion. Other configurations are the same as those of the above-described embodiment.

When the holding portion 53a is provided with the protruding portion 53d, the outer surface of the switch case 11 and the protruding portion 53d come into contact with the hand when the user holds the switch 1. Since the waterproof member 5 is formed of an elastic material, the waterproof member 5 is well adapted to a hand. That is, since the protruding portion 53d protrudes from the outer surface of the switch case 11, the finger is well caught and the protruding portion 53d is protruded.
Since d has elasticity, it does not slip off the hand. For this reason, even if the hand is wet, the switch 1 with excellent operability can be provided by effectively using the waterproof member 5.

The protrusion 53d is not limited to being formed over the entire periphery of the mating portion between the front case 2 and the back or the bar 4, but may be provided partially. The shape of the protruding portion 53d is not limited to a semi-circular cross section as shown in FIG. 5, but various shapes such as a rectangular or triangular cross section can be adopted.

FIG. 6 shows still another embodiment.
The switch 1 according to this embodiment does not include the inner case 3 inside. The shapes of the front case 2 and the back cover 4 and the shape of the waterproof member 5 are substantially the same as those of the above-described embodiment.

Also in the switch 1 shown in FIG. 6, the holding portion 53a of the waterproof member 5 is provided with a protruding portion 53d protruding outside the outer surface of the joint portion between the front case 2 and the back cover 4. It may be.

The present invention is not limited to this, and can be used for various applications such as application to an emergency switch for a toilet or application to an emergency switch for a hospital. Further, as the installation state of the switch, it is possible to apply various installation states, such as mounting on a wall or hanging the switch.

The switch case 11 of the switch 1
Has two cover members, the front case 2 and the back cover 4, but the switch case 11 may be configured by three or more cover members. In this case, it is necessary to improve the outer edge sealing portion 53 of the waterproof member 5 so that the mating portion between the cover members can be sealed.

Further, the waterproof member 5 is formed of milky white silicone rubber, but the present invention is not limited to this.
A transparent material, a translucent material other than milky white, or a rubber material other than silicone rubber may be used.

Further, in each of the above-described embodiments, the switch plate 27 is provided at only one place, but it is also possible to provide the switch plate at a plurality of places. Although the waterproof member 5 is formed of a rubber material, the waterproof member 5 can also be realized by a material such as an elastic and waterproof resin. Further, although the waterproof member 5 completely covers the inside of the front case 11, a similar effect as described above can be obtained by a structure in which a hole for passing a boss for fixing the substrate is provided.
