JP6990883B2 - Security buzzer - Google Patents

Description

The present invention relates to a crime prevention buzzer, and more particularly to a crime prevention buzzer in which erroneous operation is unlikely to occur.

Security buzzers are widely used as security equipment for children, school children, and women.
There are two characteristics required for a security buzzer, one is the speed of operation. When a danger is detected, it is necessary to immediately sound the buzzer with a simple operation.
The other is prevention of erroneous operation. That is, the buzzer should not be sounded unintentionally. The security buzzer makes a very loud noise, which can surprise the surroundings and cause temporary confusion. Therefore, it is necessary to prevent erroneous operation as much as possible.

However, the speed of operation and the prevention of erroneous operation are generally in a trade-off relationship. If the buzzer activation operation is complicated in order to prevent erroneous operation, the speed of operation is lost.
As a buzzer activation mechanism in consideration of a balance between quick operation and prevention of erroneous operation, a mechanism for pulling a string hanging downward from a security buzzer has been proposed (for example, Patent Document 1 and Patent Document 2).

Utility model registration No. 3042596 JP 2015-185980

The crime prevention buzzer disclosed in Patent Document 1 and Patent Document 2 can drive the buzzer by a relatively simple operation of pulling a string hanging downward downward, so that the speed of operation is guaranteed. Further, the drive mechanism of pulling the string hanging downward is less likely to cause an erroneous operation than the mechanism of pressing a button switch.

However, in order to pull the string hanging downward downward, it is necessary to provide a grip portion at the tip of the string, which is easy to grip by hand. For example, in a configuration without a gripping tool as in Patent Document 2, it may happen that the string cannot be gripped in an emergency and the buzzer cannot be driven.
On the other hand, when the gripping tool is provided, another problem arises that the gripping tool is easily caught by something and erroneous operation occurs.

In consideration of the above problems, the present invention proposes a crime prevention buzzer that achieves both quick operation and prevention of erroneous operation as much as possible.

A speaker for issuing an alarm, and
The control circuit that controls the speaker and
The power supply for driving the speaker and the control circuit,
A switch for turning on / off the alarm of the above speaker,
With the main body equipped with
A string-like body provided on the switch and partially or completely exposed outside the main body,
The fixed part provided on the string-shaped body and
Have,
The main body is provided with a fixing means for detachably fixing the fixing portion to a predetermined position of the main body by fitting or magnetic force .

Since the security buzzer according to the present invention is configured as described above, it has the effects of many of the inventions shown below.

First, since the fixed portion, which is a gripping tool, is detachably fixed to the main body, there is no risk that the fixed portion will be caught by something. Further, in the state where the fixed portion is fixed to the main body, the string-shaped body is folded in two. That is, since the actual length is halved, the risk of the string-like body getting caught in something can be greatly reduced. Therefore, erroneous operation is unlikely to occur.

Second, when activating the buzzer, the fixed part should be grasped, removed from the main body, and pulled downward. Since the fixed portion is fixed to the main body, the position is easy for the user to understand and can be reliably grasped and pulled. Alternatively, when the string-shaped body is pulled down with a finger, the fixed portion comes off from the main body and falls downward, so that the fixed portion may be grasped as it is and pulled further downward. In this way, the buzzer can be activated by a linear motion of lowering the hand, so that the buzzer can be activated quickly. In particular, the fixing portion may grab the outside of the ring or put a finger in the ring. Since the fixed part can be made relatively large to the same extent as the main body, it is easy to apply force when pulling it downward. Therefore, since the operation load can be increased, it is possible to make it more difficult for erroneous operation to occur.

Thirdly, it is unnecessary to provide another switch for preventing erroneous operation, the control circuit, the switch mechanism, and the like are not complicated, and the component cost and the manufacturing cost are not increased.

Fourth, when walking on a dark night road, the buzzer can be activated more quickly if the fixed part is removed from the main body in advance. In this way, with the simple operation of attaching and detaching the fixed part from the main body, it is possible to use it properly in normal times and in potentially dangerous situations.

Fifth, if the structure is such that the fixed part can be fixed so as to cover the entire surface of the main body, the fixed part plays a role of absorbing the impact when the security buzzer is hit, and the impact on the security buzzer is reduced. can. Usually, the security buzzer is often attached to the front side of the user's body for easy operation, and therefore, the front surface of the security buzzer is often hit. It is natural that the fixing portion is provided on the front surface of the security buzzer so that it can be easily attached and detached, and therefore it is easy to configure the product to protect the security buzzer.

Sixth, considering the combination with the fixed part itself or the main body, the degree of freedom in designing is expanded, and it is easy to make it an attractive product for children and women to wear.

Seventh, if a fixing part or a string-like body is provided with a mounting tool that can be detachably attached to a bag or clothing, the buzzer can be operated by pulling the main body.

It is a perspective view of the state which attached the fixed part of the security buzzer which concerns on this invention. It is a perspective view of the state which the fixed part of the security buzzer which concerns on this invention is removed. It is a perspective view of the back side of the security buzzer body which concerns on this invention.

Embodiment.
Hereinafter, the configuration, usage method, advantages, and the like of the security buzzer according to the present invention will be described with reference to the drawings. It should be noted that the following embodiments are the optimum examples of the present invention, and the present invention is not particularly limited to this example.

<Structure>
First, the configuration will be described.
FIG. 1 is a perspective view showing a state in which a fixed portion of the security buzzer according to the present invention is attached. Further, FIG. 2 is a perspective view showing a state in which the fixed portion of the security buzzer according to the present invention is removed.

As a basic configuration of the security buzzer, a speaker for issuing an alarm, a control circuit for controlling the speaker, a power supply for driving the speaker and the control circuit, and an alarm of the speaker are turned on / off. A main body 1 provided with a switch 1b for the purpose, a string-shaped body 3 provided on the switch 1b and partially or completely exposed to the outside of the main body 1, and a fixing portion 4 provided on the string-shaped body 3. have. The main body 1 is provided with a fixing means 1a for detachably fixing the fixing portion 4.

The crime prevention buzzer according to the present invention is provided on the main body 1 and has a mounting tool 2 that can be detachably attached to a bag or clothing. With this attachment 2, the main body 1 can be attached to a bag or clothing, and the buzzer can be operated by pulling the string-shaped body 3 or the fixing portion 4 downward.
However, it can be used in other ways. For example, the string-shaped body 3 or the fixing portion 4 is provided with a mounting tool that can be detachably attached to the bag or clothing, and the string-shaped body 3 or the fixing portion 4 is attached to the bag or clothing by this mounting tool. The buzzer can also be activated by pulling the main body 1 downward.

It is desirable that the fixing portion 4 has a ring shape having an inner hole 4a. As shown in FIG. 1, it is possible to fix the main body 1 to the fixing means 1a by using the inner hole 4a. Further, when operating the buzzer, it is possible to put a finger in the inner hole 4a and pull it strongly.

The speaker for issuing an alarm is a speaker capable of emitting a loud volume, and is therefore a speaker that is somewhat loud. For example, in FIG. 2, a circular speaker is provided near the portion 1a of the housing of the main body 1. If this portion is set to a portion where the fixing portion 4 is detachably fixed, the whole can be compactly organized. That is, the fixing means 1a for detachably fixing the fixing portion 4 is provided in a portion of the housing of the main body 1 that includes the speaker, and the portion can insert the inner hole 4a of the fixing portion 4. As a result, the fixing portion 4 can be attached to the main body 1 by using the housing portion including the speaker, which is a large component.
Of course, the above is an example of fixing the fixing portion 4 to the main body 1, and any form may be used as long as it can be detachably fixed.

Further, it is desirable that the fixing portion 4 is attached to the front side of the main body so that it can be easily attached and detached. Similarly, it is desirable to attach the speaker to the front side of the main body in order to efficiently transmit the alarm sound to the front. From this point of view, it is rational as a whole configuration to attach the fixing portion 4 by using the portion including the speaker.
The main body 1 and the fixing means 1a of the fixing portion 4 may be fitted or may use a magnetic force or the like.

The switch 1b is a switch, a rotary switch, or the like, and in FIG. 2, the switch 1b is a switch in which the buzzer is activated by pulling the string-shaped body 3 downward. It is desirable that a part of the switch 1b is outside the main body 1. The reason will be described later.
The string-shaped body 3 is a string, a chain, or the like. The length needs to be longer than the length required when attaching the fixing portion 4 to the main body 1, but it is better not to be too long. This is to prevent the string-shaped body 3 from being caught in something and causing an erroneous operation.

The fixture 2 is a hook or the like, and is used for detachably attaching to a bag, clothing, or the like.
Further, although FIG. 3 shows a perspective view of the back surface side of the security buzzer main body 1, a mounting tool 1c may be provided on the back surface of the main body. It is also possible to pass a band-shaped hook-and-loop fastener through the fixture 1c and fix it to the shoulder strap of a school bag or shoulder bag. As a result, for example, the main body 1 of the security buzzer can be positioned near the right chest, and the operation can be easily performed.
For example, in the case of a school bag, if the attachment 2 is attached to the D ring of the shoulder belt and the shoulder belt is wrapped with a band-shaped hook-and-loop fastener passed through the attachment 1c, the security unit buzzer body 1 can be firmly fixed near the chest. .. When passing the band-shaped surface fastener through the mounting tool 1c, a ring-shaped metal fitting may be passed through the mounting tool 1c, and the band-shaped surface fastener may be passed through the ring-shaped metal fitting.

<How to use>
Next, how to use it will be described.
Under normal conditions, the fixing portion 4 is fixed to the main body as shown in FIG. Then, the main body 1 is attached to a bag, clothing, or the like by using the attachment 3 or the attachment 1c. The mounting position should be as easy to operate by hand as possible. As mentioned above, it is desirable to be as high as possible on the front of the body such as the chest.

Next, when some danger is detected, the fixing portion 4 is grasped, removed from the main body 1, and pulled downward. Or pull the string 3. Then, the fixing portion 4 comes off from the main body 1 and falls downward. Therefore, either grasp the outside of the fixing portion 4 or put a finger in the inner hole 4a of the fixing portion 4 and pull it downward. Then, the switch 1b moves downward and the switch is turned on. As a result, the control circuit that controls the speaker drives the speaker, and the speaker issues an alarm.

These movements after pulling the fixing portion 4 or the string-shaped body 3 are movements in which the hand moves downward substantially linearly, and can be performed quickly.
In addition to such an operation, the fixed portion may be pulled downward after being separated from the main body 1 by an operation such as wiping the side surface of the fixed portion 4 by hand.

When the alarm is stopped, the switch 1b is pushed back upward. The reason why it is desirable that a part of the switch 1b is outside the main body 1 is to allow the switch 1b to be pushed back upward.
Although another switch may be provided in the main body 1 to stop the alarm, the cost increases because the number of parts increases. In addition, since the switch 1b needs to be returned upward anyway, it is better to return the switch 1b to the original position to stop the alarm than to provide another switch, because no extra operation is required. ..
