Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display case, and more particularly to a display case equipped with an alarm device.

[0002]

2. Description of the Related Art Usually, as a case for displaying products, there is a case provided with a sliding glass opening / closing door for opening / closing a front opening of the display space room.

Conventionally, as a measure against theft of goods in such a display case, for example, both sliding doors are locked so that they cannot be opened or closed.

[0004]

As described above, the opening and closing doors are locked with each other to prevent the theft of goods. If there is, there is a problem of fear of theft.

Further, depending on the type of the product, it may be difficult to lock the key when the product is frequently put in and taken out of the display case. It was difficult to deal with theft.

[0006] Therefore, it is an object of the present invention to provide a display case capable of preventing theft of a product even when it is not locked.

[0007]

In order to solve the above-mentioned problems, the display case of the present invention is a double-door type or a sliding type that can open and close a space for displaying goods and a front opening of the space for displaying. And a detection means for detecting the open / closed state of the open / close door, and a detection signal from the detecting means is inputted, and the open / close door emits light when the open / close door is in the open state. It is provided with a control means for activating an alarm means including a body and / or a sounding body.

According to this structure, when the opening / closing door provided in the front opening of the display space is opened, the luminous body and / or
Or, the alarm means such as the sounding body is activated, so that the store clerk can easily know the opened state of the opening / closing door. Therefore, even if the operator forgets to lock the opening / closing door, or the key cannot be attached, a sufficient product The anti-theft function of can be demonstrated.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION A display case for goods according to an embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

As shown in FIG. 1, this display case (also referred to as a showcase) 1 has a box-shaped base portion 2 at the lower part and a box-shaped product display space provided above the base portion 2. A display section 4 having a chamber 3, and a pair of left and right glass open / close doors provided in the front opening of the display space room 3 in the display section 4 and capable of opening and closing the front opening. It is composed of 5 and.

In the display case 1, when the opening / closing door 5 is opened, an alarm device (which is also a crime prevention device) 6 for detecting the opened state and notifying the clerk of the opening state, for example. It is equipped.

The alarm device 6 is attached (or attached) to the base portion 2 side corresponding to the opposite side end portions (end portions near the center of the front opening) of the respective opening / closing doors 5 having large swinging amounts at the time of opening and closing (or. (Embedded) A pair of detection sensors (detection means) 11 capable of detecting the open / closed state of each open / close door 5, and a detection signal from each of these detection sensors 11 is input to open at least one open / close door 5. In this case, a control box 13 having a control unit (not shown, for example, a control circuit or the like) for outputting a signal for operating an alarm device (alarm means) 12 provided in the display case 1 is configured. Has been done. Of course, the alarm device 12 is a part of the alarm device 6.

More specifically, the above-mentioned detection sensor 1
As 1, for example, a light reflection type photoelectronic sensor is used, and when the opening / closing door 5 is closed, the light emitted from the light emitting portion of the photoelectronic sensor hits the bottom surface of the opening / closing door 5, and reflects the reflected light. The light receiving unit detects the open / closed state of the open / close door 5 and outputs the detection signal to the control unit.

The alarm 12 is provided with two types, a light emitting body and a sounding body, and specifically, a lamp 12A.
And a buzzer 12B is provided. The lamp 12A is provided at a position easily visible from the outside of the opening / closing door 5 in the display space 3, and the buzzer 12B is
As shown in FIG. 2, the control box 1 is arranged in the base 2.
It is provided in 3. In addition, the control box 13 has a buzzer 12B.
In addition to the above, an entire power switch 21, a switch 22 for the detection sensor 11, a switch 23 for the lamp 12A, and a switch 24 for the buzzer 12B are provided.

The control unit or control circuit provided in the control box 13 inputs signals from two detection sensors 11 for detecting the open / closed state of each door 5,
The logical sum of these two signals is output, and the drive relay (drive circuit) of the lamp 12A and the buzzer 12B is operated based on the output signal. Of course, the detection sensor 11 and the lamp 12A, The control circuit, which is the control unit, is connected by electric wires.

In the display case 1, the alarm device 6
When activating, the power switch 21 of the control box 13 is turned on, and the switch 22 of the detection sensor 11, the switch 23 of the lamp 12A and the switch 24 of the buzzer 12B are turned on.

In this state, for example, when the customer opens the opening / closing door 5 in order to take out the product, the detection sensor 11 detects that and the detection signal is input to the control unit.
Then, the lamp 12A lights up and the buzzer 12B
Sounds, the clerk immediately knows that the opening / closing door 5 has been opened, and can therefore pay attention to theft and the like. That is, the crime prevention function for the product works sufficiently.

Further, unless the door 5 is closed after the product is taken out or returned, the lamp 12A
Further, since the operation of the buzzer 12B continues, it is possible to prevent forgetting to close the opening / closing door 5, and thus to prevent the theft of the product and the like more reliably.

The alarm device 6 informs the store clerk of the open / closed state of the opening / closing door 5, and therefore, should be locked when the opening / closing door 5 has a key and the product is not taken in or out. Good.

Further, in the above description, the lamp 12A
Although both the buzzer 12B and the buzzer 12B are used, either one may be used depending on the type of the store or the product to be displayed. Of course, in this case, the switch 23 or 24 provided in the control box 13 may be turned off. The buzzer 12B may also be music that does not cause discomfort to the customer, instead of so-called warning sound.

Further, the lamp 12A and the buzzer 1
2B is attached to the display space 3 and the control box 1
The number is not limited to 3, and may be an arbitrary position in the display case or the outer surface or the outer side of the display case.

Further, in the above description, the photoelectric sensor is used as the detection sensor, but the detection sensor is not limited to this, and for example, a magnet type sensor may be used.

In the above embodiment, the opening / closing door 5 has been described as a double door type, but as shown in FIG. 3, for example, the opening / closing door 5'is also applicable to a sliding type in which the opening / closing door 5'slides left and right. be able to. Note that FIG.
In FIG. 1, the same members as those of the display case described with reference to FIG. In this case, the pair of detection sensors 11 are attached to the base portion 2 side of the front opening of the display space chamber 3 near both ends.

[0024]

As described above, according to the structure of the display case of the present invention, when the opening / closing door provided in the front opening of the display space room is opened, a warning means such as a light emitting body and / or a sounding body. Since the clerk operates, the store clerk can easily know the open state of the open / close door, so even if you forget to lock the open / close door, or if the key cannot be attached, a sufficient product theft prevention function can be obtained. To be
