Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a security device provided at an entrance door or the like.
[0002]
[Prior art]
The entrance doors of condominiums, etc. have a design structure where the installation mail reception door and the door lock are attached in the vicinity of the same door. Currently, these door structures are exploited to receive the mail etc. provided on the front of the door. There have been a series of theft cases where the mouth is broken or deformed and the hand is inserted from the outside to unlock or destroy the door lock and enter the house.
However, there has not been developed a powerful obturator that closes these theft means and mail receiving doors to prevent breakage of the lock or intrusion due to unlocking.
[0003]
[Problem to be Solved by the Invention]
In view of the above-mentioned thief case, the present invention attaches a powerful obturator that closes a mail insertion port provided at an entrance door or the like as a problem to solve this, and prevents locking damage installed at the entrance door. The problem was to propose an obturator for crime prevention.
[0004]
[Means for Solving the Problems]
As means for solving the above-mentioned problems, a corrosive-resistant flexible material is used as a molding material to form a closing tool for closing the mail insertion port, and secondly, the front and rear surfaces of the mail insertion port, that is, the door A structure that can be attached to the front and back in an integrated manner that is difficult to break, and thirdly, the obturator has a structure that allows anyone to assemble and install each part as a part, and can be provided at a practical cost. The means was to use a security device.

DETAILED DESCRIPTION OF THE INVENTION
Examples effective as embodiments of the present invention will be described below.
FIG. 1 is an overall perspective view of the obturator of the present invention, and FIG. 2 is a perspective view showing the assembly member of FIG.
In the drawings, reference numeral 10 denotes an obturator according to the present invention, which is formed of a metal or a synthetic resin material having a strong corrosion resistance and a flexible bending material. 11 is a front plate of a closing tool that closes a mail insertion slot, and 12 and 12 are connecting plates in which the upper and lower end surfaces of the front plate are bent and protruded from the upper and lower sides in the direction perpendicular to the front plate. The protruding plate is inserted into the equal insertion port h. Reference numerals 13 and 13 denote engaging pieces obtained by bending the tip of the connecting plate, and reference numeral 14 denotes a support plate attached to the engaging piece 13.
The connecting plate 12 has a dimension that protrudes from the rear surface of the mail insertion slot h, that is, the back surface of the door a. , 15 and 15 are fitting grooves provided on the support plate 14 for engaging and engaging the engaging pieces 13 of the connecting plate 12 so as to integrally support the front plate and the connecting plate.
Reference numeral 16 denotes a reinforcing plate provided with bent pieces 17 and 17 on the U at both ends for attaching the engagement pieces 13 and the support plate 14 at the ends, and the rear face of the post insertion port h provided on the door a. It is a strong reinforcing plate that integrally covers the closing plate and covers the front and rear surfaces of the mail insertion port h so that it is difficult to remove or break from the outside. .
[0006]
In the above structure, each member part is made of the same material, and can be easily assembled and mounted by ordinary people, and the obturator which does not require a fixing screw or the like is used as an example, but the reinforcing plate on the rear surface in contact with the inside of the door May be fastened or fastened with a set screw or the like.
As shown in the sectional view of FIG. 4, the obturator is a crime prevention device that is integrally attached to the front and rear surfaces of the door “a” provided with a mail insertion port “h” provided in the door “a”. It is good also as a connection board which makes it the strong connection board which bent the front-end | tip of the connection board 12 inside, and facilitates the insertion attachment to the insertion ports h, such as a mail.
[0007]
【The invention's effect】
As described above, the obturator of the present invention has a strong insertion of the mail door of the general-purpose door provided close to the lock provided on the front door over the front and the back of the door, and from the outside. Since it is a structural tool that is difficult to remove and destroy, there is an advantage that is effective as a security tool.
In addition, by using a practical obturator that is advantageous in terms of cost due to the same material, it can be used as a simple crime prevention obturator in that anyone can easily attach it without using other fasteners.
In addition, it is possible to make an embodiment by using a strong corrosion-resistant material that is excellent in durability and that has a closure having a size that fits the size of a mail outlet provided in a conventional existing door. Is prominent as a security tool.
