Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a security device provided on an entrance door or the like.
[0002]
[Prior art]
Entrance doors of condominiums, etc. are designed to have a postal door for installation and a door lock installed close to the same door. Theft incidents in which the mouth is destroyed or deformed and the door is unlocked or destroyed by inserting a hand from the outside to unlock or destroy the door and intrude into the house have been repeated.
However, on the other hand, there has not been developed a powerful closing device which closes the stolen means or the receiving port such as mail to prevent breakage of the lock or intrusion by unlocking.
[0003]
[Problems to be solved by the invention]
The present invention has been made in view of the above-mentioned thieves, and as a problem to be solved, a strong obstruction device for closing a mail inlet provided at an entrance door or the like is attached to prevent a lock damage installed at the entrance door. The purpose of this study was to propose a closure device for crime prevention.
[0004]
[Means for Solving the Problems]
As means for solving the above-mentioned problems, as a closing member for closing the mail insertion port by using a corrosion-resistant flexible material as a molding material, secondly, the front and rear surfaces of the mail insertion port, that is, the door. Third, the obturator has a structure in which anyone can assemble and install each part as a part, and can be provided at a practical cost. The means was to use security equipment.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an example which is effective as an embodiment of the present invention will be illustrated and described.
FIG. 1 is an overall perspective view of the obturator of the present invention, and FIG. 2 is a perspective view showing an assembly member of FIG.
In the drawings, reference numeral 10 denotes a closure of the present invention, which is formed of a metal or synthetic resin material made of a corrosion-resistant strong and flexible material. Reference numeral 11 denotes a front plate of an obturator for closing an insertion port for mail or the like, and 12 and 12 denote connecting plates formed by bending upper and lower end surfaces of the front plate and projecting to upper and lower side surfaces in a direction perpendicular to the front plate. A projecting plate to be inserted into the equal insertion port h. Reference numerals 13 and 13 denote attachment pieces obtained by bending the ends of the connection plates, and reference numeral 14 denotes a support plate that is attached to the attachment pieces 13.
The connecting plate 12 is dimensioned so as to protrude from the rear surface of the mail insertion port h, that is, the rear surface of the door a, and the supporting plate 14 is engaged with the engaging pieces 13 at the leading ends, and the connecting plates 12 are fixed. Reference numerals 15 and 15 denote fitting grooves provided in the support plate 14 for engaging and engaging the engaging pieces 13 of the connecting plate 12 to integrally support the front plate and the connecting plate.
Reference numeral 16 denotes a reinforcing plate provided with bent pieces 17, 17 on the U at both ends for attaching the tip of the attachment piece 13 and the support plate 14 in a conjugate manner, and a rear face of a mail insertion port h provided on the door a. A strong reinforcing plate that integrally covers the closing plate and covers the front and rear surfaces of the mail insertion port h so as to function to make it difficult to remove or break from outside. .
[0006]
In the above structure, each member is made of the same material, so that ordinary people can easily assemble and attach it, and the embodiment uses a closure that does not require fixing screws etc., but a reinforcing plate on the rear surface that contacts the inside of the door May be fastened or fastened with a set screw.
As shown in the cross-sectional view of FIG. 4, the closing device is a security device that is integrally mounted over the front and rear surfaces of the door a provided with the mail insertion port h provided on the door a, as shown in FIG. The connecting plate 12 may be formed as a strong connecting plate with the distal end bent inward, and may be a connecting plate for facilitating insertion and attachment to the insertion port h such as a mail.
[0007]
【The invention's effect】
As described above, the obturator according to the present invention is such that the mail insertion port of the general-purpose door provided in the vicinity of the lock provided on the front door is strongly fitted integrally over the front and back of the door. Since it is a structural tool that is difficult to remove and break, there is an effective advantage as a security device.
Further, by using a practical closing device made of the same material, which is advantageous in terms of cost, it can be used as a simple security closing device because anyone can easily attach it without using other fixing devices.
In addition, it is possible to adopt an embodiment in which a closing tool having a dimension suitable for a postal outlet dimension provided in a conventional existing door has excellent durability with a strong corrosion-resistant material. Is remarkable as a security device.
