Description

TREASURY

Technical Field

The present invention relates to a treasury provided with an alarm, and more particularly, to a treasury provided with a burglarproof alarm, which can sense illegal movement of the treasury itself as well as illegal opening of the treasury's door.

Background Art

A treasury refers to a means for safely safekeeping valuables such as cash, stocks and bonds, various precious metals and jewels, etc., which is generally known as a strong structure usually made of a metal. The treasury is constructed to have an inner space that is enclosed by a strong and thick metal wall in order to prevent illegal opening of the door except for the opening of the door using a specific password, a dedicated key, etc.

Most of the treasuries include a large scaled treasury permanently fixed to the building. Such a fixture type treasury is characterized in that it is constructed to prevent only illegal opening of the door. Korean Utility Model Registration No. 1981-496 discloses a burglarproof alarm device. This device has a V.H.F transmitter built therein. The V.H.F transmitter has a switch for sensing the opening of the door. This alarm device constructed as above expands noise generated within or around the treasury and then wirelessly transmits the expanded noise to a supervisor at a remote place so that he or she can take an appropriate measure for an illegal opening of the treasury. P T/KR2003/001162

However, the prior art device has a disadvantage in that it is effective only in the a large scaled treasury of a fixture type, but does not have a special countermeasure in the case where the treasury itself is illegally moved due to its small size. In particular, as a small-sized treasury is frequently used in the daytime, it is required that the small-sized treasury be easy to move. Due to this, fixing the small-sized treasury permanently causes inconvenience. Further, the small-sized treasury can be easily moved at night due to its lightness. Accordingly, there has been a problem in that it is difficult to sense and prohibit illegal movement of the small-sized treasury.

Disclosure of Invention

Accordingly, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a treasury provided with a burglarproof alarm, which can sense illegal movement of the treasury itself as well as illegal opening of the treasury's door.

To achieve the above objects, according to the present invention, there is provided a treasury including a V.H.F transmitter having a microphone and a micro switch for sensing the opening of a door as a sensor, wherein at least two micro switches serving as a movement sensing switch and a door sensing switch are connected in parallel to the V.H.F transmitter, and a variable rod of the movement sensing switch is installed to contact the ground where the treasury is located and a variable rod of the door sensing switch is installed to contact the inner surface of the door.

Best Mode for Carrying Out the Invention

The present invention will now be described in detail hereinafter in connection with preferred embodiments with reference to the accompanying drawings.

As shown in FIG. 1, a treasury including a V.H.F transmitter 33 having a microphone 34 and a micro switch for sensing the opening of a door 2 as a sensor according to the present invention, includes at least two micro switches each serving as a movement sensing switch 4 and a door sensing switch 5, which are connected in parallel to the V.H.F transmitter 33, wherein a variable rod 42 of the movement sensing switch 4 is constructed to contact the ground where the treasury is located and a variable rod 42 of the door sensing switch 5 is construct to contact an inner surface of the door 2. The sensor including the V.H.F transmitter 33 having the microphone 34 and the micro switch for sensing the opening of the door 2 has the same construction as that disclosed in Korean Utility Model Registration No. 1981-496. It will be apparent to those skilled in the art that the V.H.F transmitter 33, the microphone 34, the micro switch, etc. are well known in the art such that they can easily use them. In the present invention, they may be constructed to be same or similar as the above.

As shown in FIG. 2, one micro switch senses illegal opening of the door 2, and at the same time, the other micro switch including the movement sensing switch 4 senses illegal movement of the treasury itself.

The door sensing switch 5 is installed within the treasury in such a manner that the front end of the variable rod 42 thereof is in contact with the inner surface of the door 2. The movement sensing switch 4 is installed on the bottom surface of the treasury in such a manner that the front end of the variable rod 42 thereof is in contact with the ground where the treasury is located. Moreover, the door sensing switch 5 and the movement sensing switch 4 are connected in parallel to the V.H.F transmitter 33. Therefore, when either illegal opening of the door 2 is sensed or illegal movement of the treasury itself is sensed, a warning sound is generated from a buzzer 35 of the sensor and a radio signal corresponding to the warning sound is transmitted to a supervisor at a remote place who is wirelessly informed of the state of the treasury. The micro switch as both the door sensing switch 5 and the movement sensing switch 4 is shown in FIG. 3. It is believed that the micro switch is well known to those skilled in the art so that it can be commercially available to them. For reference, the construction of the micro switch will now be described with reference to FIG. 3.

The variable rod 42 is variably attached within a switch housing 41. A spring support plate 43 integrally formed with the variable rod 42 is resiliently supported by a spring 44. Contacts 45 are formed to be adjacent to the spring support plate 43. An electric wire 46 is connected to the contacts 45. The variable rod 42 is always forwardly resiliently supported by the spring 44. Therefore, in the case where the variable rod 42 is forcibly pushed in due to an external pressure, i.e., the contact with the door 2, etc., the spring support plate 43 is electrically disconnected from the contacts 45, so that an electric current does not flow into it. On the contrary, in the case where there is no force applied to the variable rod 42 such as when the door 2 is opened, etc., the variable rod 42 moves forward by the restoring force of the spring 44 and resultantly the spring support plate 43 comes in close contact with the contacts 45, so that the electric current can flow into it to perform a switching function. Furthermore, the electrical flow may be constructed as opposed to the above

An alarm 3 is installed on the inner bottom of the treasury. A decoration plate 11 is covered on the alarm so that the alarm 3 is not exposed to the inner space of the treasury. Moreover, the alarm 3 may have an additional alarm-driving switch 32 connected thereto. Thus, in the case where the treasury is frequently used in the daytime, the alarm-driving switch 32 may be turned off in order to prevent the operation of the alarm 3. Accordingly, a user can selectively operate the alarm 3 if a security is needed at night. The alarm-driving switch 32 may be installed to be exposed to the inner space of the treasury from the decoration plate 11 if the decoration plate 11 is attached on the alarm. Furthermore, the V.H.F generated from the alarm 3 may be sensed by a receiver at a remote place through an antenna 6. The receiver may include a receiver such as a common FM radio. The signal transmitted in the V.H.F by the receiver is converted into a sound signal of an audible band, so that a supervisor at a remote place can hear the sound. The alarm 3 includes a power supply 31 for supplying the power energy for generating the V.H.F, the alarm-driving switch 32, the V.H.F transmitter 33, the microphone 34 connected to the V.H.F transmitter 33 for detecting a sound signal, the buzzer 35 for generating a warning sound. The door sensing switch 5 and the movement sensing switch 4 as the micro switches are connected in parallel to the alarm 3. In addition, the treasury according to the present invention may further include a picture frame 51. Various photos, pictures, letters, etc, may be decorated on the picture frame 51 in order to give a decoration effect, i.e., an interior effect. In this case, the picture frame 51 may be attached to the front face of the door in the treasury, as shown in FIG. 4. At this time, the handle, the dial, etc. that are usually located at the central front face of the door may be located at one side of the front face of the door. It should be noted that the picture frame 51 might be constructed so that various photos, pictures, letters, etc, can be directly inserted into or directly removed from it .

In particular, it is preferred that the picture frame 51 may be hingeably coupled to the body 1 of the treasury so that it can completely cover the front face Of the treasury. In this case, the hinged portion may be installed in such a manner as to be concealed by the picture frame 51. As a result, it is possible to prevent the exposure of the treasury to the outside. At this time, the door 2 of the treasury is also concealed by the picture frame 51.

Industrial Applicability

As described above, the present invention provides a treasury provided^' with a burglarproof alarm 3, which can sense illegal movement of the treasury itself as well as illegal opening of a door 2. Therefore, the present invention has a new effect that it can prevent illegal opening of the door 2 and illegal movement of the treasury itself, in particular in a small-sized treasury.

While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
