Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a magnet-based locking device that can be used, for example, to lock a zipper knob used to open and close a lid of a bag.
[0002]
[Prior art]
A lock device using a normal key that has been used in the past can be unlocked when the unevenness carved on the key matches the lock pin or lock piece on the lock device side. When inserted, there was a problem that it was necessary to get over the lock pin and the lock piece, and sometimes it could not be inserted and removed smoothly.
[0003]
Therefore, a magnet-based locking device that opens and closes the lock by moving the slider along with the key using the repulsive force of the magnet installed in the key and using the repulsive force with the magnet arranged on the lock device side was considered. It was inevitable that the key could be removed while moving the key, and it was not clear whether it was at the unlocked position or the unlocked position that is the two ends of the slider movement.
[0004]
[Problems to be solved by the invention]
The present invention eliminates the above-mentioned problems, and prevents the key from being removed during the movement of the slider, and also uses a magnet-based locking device so that it can be seen that the locking position and the unlocking position are the opposite ends of the movement of the slider. The challenge is to obtain
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the present invention utilizes the repulsive force between the magnet built in the key and the magnet disposed on the lock device side, and moves the slider together with the key. In a lock device using a magnet that opens and closes the lock device, the key during slider movement can be obtained by a combination of a hole provided in the key, an uneven portion provided in the lock device, and a clip pin and a click pin spring interposed therebetween. A magnet-based locking device is obtained which is configured to generate a click sound at both ends of slider movement without falling out.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 5 shows the configuration of the locking device 10 using the magnet according to the present invention with the outer main body 70 removed, and FIG. 6 shows the AA cross section of FIG. The main body 70 is indicated by a two-dot chain line. In the figure, 20 is a slider, 30 is a slider cover, 40 is a stopper for locking the hook 50, and 60 is a push for operating the hook. (Details of the operation of this locking device will be described later.) As shown in FIG. 6, the magnet 80 in the magnet holding hole 24 of the slider 20 is pushed by the magnet spring 81 into the recess 79 provided in the back plate 75. The slider 20 cannot move relative to the back plate 75. FIG. 7 shows that the key 5 is inserted into the keyway 21 of the slider. The magnet 7 incorporated in the key 5 and the magnet 80 described above repel each other, and the magnet 80 resists the spring 81. The slider 20 moves backward and comes out of the recess 79 of the back plate 75, so that the slider 20 can move together with the key 5.
[0007]
Reference numeral 73 denotes a click pin, which is held in the click pin holding hole 25 of the slider 20 and is pressed against an uneven portion 76 provided on the back plate 75 by a click pin spring 74. FIG. 29 is a cross-sectional view of FIG. 6 as viewed from the R direction. FIG. 29A shows that the key 5 is inserted into the keyway 21 of the slider 20, and the head of the click pin is the back plate. Since it is located at the concave portion of the concavo-convex portion 75, the head of the click pin is pushed into the concave portion by being pushed by the click pin spring 74, the click pin 73 has come out of the hole 6 of the key 5, and the key is free. Can be inserted and removed. (B) shows the state in which the key 5 and the slider 20 are moved together to the right in the figure. The head of the click pin 73 comes to the convex portion of the concavo-convex portion 76, so the click pin 73 is clicked. The pin spring 74 moves up against the pin spring 74, and the tip of the pin spring 74 enters the hole 6 of the key 5. The key 5 does not come off during movement. (C) is the state where the opposite end has been reached, and the other end of the click pin head, for example, is pushed by the click pin spring 74 and suddenly enters the recess due to the click pin head again coming into the recess of the uneven portion 76. The key 5 can be extracted from the keyway 21 of the slider 20 while it is clearly seen that (the locked position or the unlocked position) has been reached. As can be seen from the figure, the key 5 and the slider 20 move at right angles to the paper surface in FIGS. 6 and 7, and this is the left and right movement on the paper surface in FIG. 28 when FIG. 6 is viewed from the R direction.
