Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a security guard attached to a vending machine, and more particularly to a security guard for a vending machine capable of preventing damage by a drill or a grinder.
[0002]
[Prior art]
Conventionally, in order to prevent damages such as destruction and theft from vending machines, security guards are attached. Here, the conventional example of the security guard for vending machines will be specifically described with reference to FIG. As shown in FIG. 6, the vending machine 1 includes a main body box 2 in which merchandise and other internal devices are accommodated, and a door 3 provided on the front surface of the main body box 2 so as to be opened and closed.
[0003]
A keyhole portion 4 is attached to the middle of the left end portion of the door 3 in the drawing. Inside the keyhole portion 4, there is provided a lock portion (not shown) that inserts and operates a key to make the door 3 openable or non-openable. The damage to the vending machine 1 is generally a case in which a hole is drilled around the keyhole portion 4 and the door 3 is opened by damaging the key portion or the lock portion. Therefore, a security guard 5 is installed around the keyhole portion 4. The security guard 5 is usually made of a thick iron plate and is fixed to the door 3 with decorative bolts 6.
[0004]
[Problems to be solved by the invention]
In recent years, carbide drills with extremely high hardness have been put into practical use. By using this carbide drill, a hole is made in the security guard 5. Recently, handheld grinders have become widespread and their performance has been greatly improved. Therefore, damages such as scraping off the mounting bolt 6 by the grinder and removing the security guard 5 are frequently occurring. In view of such a situation, there is a demand for a strong crime prevention guard that does not open a hole even with a carbide drill and that can avoid breakage due to a grinder.
[0005]
The present invention has been proposed in order to solve the above-mentioned problems, and its purpose is to provide a crime prevention guard for vending machines with extremely high crime prevention capability that can reliably prevent damage caused by a carbide drill or a grinder. It is to provide.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention has the following features in a security guard for a vending machine attached around a keyhole for opening a door of the vending machine.
[0007]
That is, the present invention provides a security guard for an automatic vending machine which is attached to the periphery of the keyhole portion for opening the door of the vending machine, attached to the front side of the door, is fixed from the rear side of the door, the surface And a plurality of sheets made of a fibrous material are stacked and loaded inside the cover . In this invention, since a crime prevention guard is fixed from the back side of a door, in the state which closed the door, an attachment position is not known from the outside. Therefore, there is no worry that the mounting bolt is scraped off by the grinder as in the prior art. Therefore, the crime prevention guard is not removed and high crime prevention properties can be obtained.
[0009]
Furthermore, the present invention is characterized in that a plurality of sheets made of a fibrous material are stacked and loaded. Thereby, when it is going to open a hole with a drill, if the drill hits a sheet | seat, the fibrous material which comprises the sheet | seat will be torn finely. And the fibrous material torn with the rotation of the drill is entangled with the drill. At this time, since a plurality of sheets are stacked, the fibrous material is entangled with the drill in a complicated manner, and the drill can be locked. If it cannot rotate, even if it is a carbide drill, a hole cannot be made in a crime prevention guard, and the crime prevention guard can protect a key part or a lock part. Therefore, extremely high crime prevention can be exhibited. Moreover, since it is not necessary to use an iron plate, it is possible to reduce the weight.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
(1) First Embodiment [Configuration]
A first embodiment corresponding to the first and second aspects of the present invention will be described below with reference to a perspective view of FIG. 1 and a plan view of FIG. Note that members similar to those of the above-described conventional technology are denoted by the same reference numerals, and description thereof is omitted. The crime prevention guard 7 according to the first embodiment is composed of a hardened iron plate. Moreover, the crime prevention guard 7 is being fixed with the volt | bolt 6 for attachment from the back side of the door 3 (refer FIG. 2).
[0011]
[Function and effect]
The operational effects of the first embodiment having the above-described configuration are as follows. That is, the hardness of the security guard 7 can be increased by adopting a hardened iron plate. Therefore, even if it is a carbide drill, the drilling operation becomes difficult, and breakage due to the drill can be prevented. Moreover, since the crime prevention guard 7 is fixed from the back side of the door 3, when the door 3 is closed, the mounting position is not known from the outside, and there is no fear that the mounting bolt 6 is scraped off by the grinder. Therefore, the removal of the crime prevention guard 7 can be prevented, and the crime prevention property is further improved.
[0012]
(2) Second Embodiment [Configuration]
Next, the second embodiment will be specifically described with reference to FIGS. The second embodiment corresponds to claims 2 and 3, FIG. 3 is a perspective view of the second embodiment attached to a vending machine, and FIG. 4 is a diagram of the second embodiment. A perspective view and FIG. 5 are AA sectional views of FIG. Note that members similar to those of the above-described conventional technology are denoted by the same reference numerals, and description thereof is omitted.
[0013]
The security guard 8 according to the second embodiment is characterized in that a plastic cover 8a is formed on the surface, and a plurality of resin cloths 9 are stacked and loaded on the inside. The resin cloth 9 is composed of a sheet made of a high-strength, high-elastic fibrous material such as Kevlar fiber. Similarly to the first embodiment, the security guard 8 is fixed from the back side of the door 3 by the mounting bolt 6.
[0014]
[Function and effect]
In the second embodiment having the above configuration, when trying to make a hole in the security guard 8 with a drill, even if the hole can be made in the cover 8a, the drill is made in the resin cloth 9. When reaching, the cloth 9 is torn finely by the drill, and the torn cloth 9 is entangled with the drill as the drill rotates. At this time, since a plurality of resin-based cloths 9 are stacked, they are entangled with the drill in a complicated manner. And the more the drill rotates, the more the resin-based cloth 9 gets entangled with the drill, and the drill can be locked. If it cannot be rotated, no matter how hard the carbide drill can be, the security guard 8 cannot penetrate the hole. Therefore, according to the second embodiment, the key portion or the lock portion can be protected, and extremely high crime prevention can be exhibited.
[0015]
Further, in the second embodiment, as in the first embodiment, the crime prevention guard 8 covers the attachment portion for the door 3, so the attachment position is not known from the outside, and the attachment portion is scraped off by a grinder. There is no fear. Furthermore, in 2nd Embodiment, since there is no iron plate used for the crime prevention guard 8, there also exists an advantage that it can reduce in weight.
[0016]
The present invention is not limited to the above two embodiments, and the size and shape of each component, the number of sheets made of fibrous resin, the type of resin, and the like can be changed as appropriate. It is. For example, the security guard may be installed on the back side of the door as long as it is around the keyhole. Moreover, as the fibrous material of the sheet | seat loaded into a crime prevention guard, what is necessary is just to become entangled as a fiber, and fibrous steel and glass fiber may be sufficient.
[0017]
【The invention's effect】
As described above, according to the security guard for a vending machine of the present invention, it is composed of a hardened iron plate, attached from the back side of the door, or loaded with a plurality of sheets made of fibrous material, Breakage due to a carbide drill or grinder can be prevented, and the key portion or the lock portion can be securely guarded to improve crime prevention.
