Abstract

[PROBLEM] To easily fix a shutter by simply inserting it into the guard rail from the inside without any work, and to open the shutter for criminal purposes from the outside, or the shutter curtain is detached from the guide rail by an unusual wind such as a typhoon Provided is an auxiliary locking device for a shutter device against crimes and strong winds, which prevents this from happening.
When the shutter curtain is inserted toward the guide rail so as to follow the slat back surface 12 on the indoor side of the shutter curtain and the knob 10 is tightened strongly, the tip 3 opens on the principle of leverage, and the shutter curtain opens in the guide rail. It is pressed against the outer side wall to fix the shutter curtain and prevent entry from the outside, and also helps to prevent the shutter curtain from being detached by wind force.

Description

  The present invention locks the shutter curtain from the inside when the shutter curtain is fully closed at the windows and entrances of stores, garages, houses, etc., thereby preventing the shutter from being opened by external force or damaged by wind pressure. It is a thing regarding the auxiliary | assistant locking structure in an apparatus.

  In recent years, shutters have been widely used not only for entrances and exits of stores and garages, but also as substitutes for shutters in windows and entrances of ordinary households.

  The shutter consists of a plurality of slats and is stored in a roll-up state. When used, the shutter is raised and lowered along the guide rails on both sides, and the bottom part of the shutter curtain and the window frame, or the keyhole and locking parts on the floor It is designed to lock automatically when it touches (when closed).

  In this structure, it was not possible to avoid the crime of inserting a bar or the like to break the locking device and invade it from the gap between the floor slightly formed by locking only the lower part and the lowermost part of the shutter curtain.

  In addition, shutters that are locked from the outside, such as stores, garages, and garages, have a keyhole on the outside, and the handle that extends from the keyhole to the left and right engages the keyhole by locking the key that is inserted into the keyhole. Although it is a mechanism that can be locked by being caught on a piece, this type is easily unlocked when the keyhole is picked. The windows and doorways of modern houses have the above two structures, but they are not perfect.

Also in auxiliary locking devices such as Patent Documents 1, 2, and 3 (Japanese Patent Application Laid-Open Nos. 2004-176420, 2005-180129, and 2007-32096), the guide rails are associated with them in advance. The stop device had to be fixed with screws, and it was impossible to install it easily. Also, because it was just an idea for crime prevention, it was not possible to prevent the shutter curtain from coming off the guide rail against strong winds during typhoons.

  The slats are alternately connected to the interlock part, and there is no work on the shutter. It is easy to insert the guide rail from the inside. The shutter is firmly fixed and the shutter is opened from the outside for criminal purposes. Provided is an auxiliary locking device for a shutter device against crimes and strong winds, which prevents the shutter curtain from being detached from the guide rails due to not wind power.

  The present invention is an auxiliary lock that enhances the security function of a shutter, and the shutter curtain includes a shutter curtain in which a plurality of slats are alternately linked to an interlock portion, and a guide rail that holds both ends of the shutter curtain. A locking device that is mounted in contact with the back surface of the slat between the interlock portion and the interlock portion on the indoor side, and is composed of two substrates, a resistance plate and each of which is fixed by a fulcrum bar-shaped member. The tip of the insertion part of the board and the resistance plate by the lever principle by tightening the knob while inserting the locking device with the interval adjusting rod-like member and the knob on the opposite side of the insertion part to the guide rail. The shutter curtain is pressed against the side wall on the outdoor side of the guide rail and fixed. Than is.

  In addition, if the locking device is a shutter with an interlock part protruding on the back surface of the slat, there is no need to make a hole in the guide rail or attach a locking plate to the guide rail in advance. It can be easily installed simply by tightening the knob with the fingertip, and because of the L-shaped protrusion at the tip of the resistance plate, it can be tightened more easily and fixed in the guide groove, and the resistance force can be increased by winding rubber. Since it does not touch the rail edge, there will be no scratches left on the guide rail.

  Even if the shutter with the existing locking device is unlocked by the power of a criminal purpose from the outside, if it is equipped with the auxiliary lock, it can not be lifted easily even if it is lifted in the opening direction, Even if the shutter is moved slightly, it is unlikely that the auxiliary lock is completely detached from the shutter because the tip portion inserted into the guide rail is widened.

  Thus, even when the locking device already mounted on the shutter is destroyed, it is possible to provide higher crime prevention means by preventing intrusion or increasing the time required for intrusion.

  As described above, the shutter lock of the present invention is detachable, but the shutter curtain is in close contact with the inner side wall of the guide rail against the force of forcibly raising the shutter from the outside. Therefore, it cannot be easily opened and can prevent entry from the outside.

  Moreover, it becomes more powerful resistance by attaching more than one, and it is possible to prevent the shutter curtain from detaching from the guide rail against strong winds.

  In the present invention, the connecting part of the substrate and the resistor plate is connected by a fulcrum bar-like member, and the guide rail insertion part opens and closes based on the principle of lever using this connecting part as a fulcrum, so the shutter curtain slats Insert the tip of the device on the back side (indoor side) of the device along the interlocking part so that the protruding part comes to the front, and to the back of the guide rail. Tighten the knob with your finger and attach it. In addition, when inserting and removing, the gap between the substrate and the resistor plate at the tip of the present invention can be easily attached / detached by loosening the knob with a finger.

A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.
Substrates and resistor plates were made of durable and strong materials. The two nuts (4a, 4b) are arranged in a straight line at the middle position which becomes the fulcrum of the lever principle. The nut and the countersunk screws (7a, 7b), which are rod-shaped members, naturally grow over time. This is to prevent loosening. Also, two nuts are inserted between the substrate (4a, 4b) and the resistor plate (5a, 6a, 5b, 6b) respectively, and the tip of the resistor plate (3) to be inserted into the guide rail. The height is adjusted as a fulcrum for opening and closing the door. The knob (10) for adjusting the opening / closing thereof includes a countersunk screw (11) and a butterfly screw, which are slightly longer, in order to make the opening angle of the tip (3) of the resistance plate wider. A nut (10) was combined, and a coil (8) was built in between. Then, the substrate is dug by the amount of the countersunk screw heads (7a, 7b, 11) so that the substrate is brought into close contact with the slats, and the surface is made uniform, and rubber (9) is attached to the tip of the resistance plate on the guide rail. It attached so that it might touch. This embodiment is as shown in the drawing, but there are many other ways to open and close on the principle of lever, such as crossing the fulcrum part like a washing scissors, and also using countersunk screws, nuts, etc. The wing nut and the like can be replaced with other rod-like members, and can be used other than the shutter device by changing the size and thickness. In addition, rubber is a thing for making it harder to move, and it may be a substitute or no rubber.
