Description

[Detailed Description of the Invention] The present invention relates to a magnetic lock, and its purpose is to securely hold the lock.

Conventionally, a pinhole is provided in a fixed lock plate,
A magnetic lock is known in which a lock pin is provided on a sliding body for locking and unlocking so as to be slidable in the axial direction, and a key plate having a magnet embedded in the sliding body in the same phase as the lock pin can be moved in and out.

However, in this conventional magnetic lock, the locking mechanism in which the lock pin and pinhole are engaged has a passive structure in which the lock pin falls into the pinhole due to its own weight.
When used in briefcases or travel cases, it has the following disadvantages:

In other words, when locking or unlocking a bag or case, it is customary to turn it sideways.

Therefore, the magnetic lock also faces sideways, and the axis of the lock pin becomes horizontal.

In this case, there is no problem in abutting the key plate and magnetically attracting the lock pin to disengage it from the pin hole, but in order to release the key plate and engage the lock pin in the pin hole, it is necessary to If you do not stand the type vertically, you will not be able to achieve the engagement effect by automatic falling.

Additionally, when a bag or case is turned in the opposite vertical direction, the lock pin that is engaged with the pinhole falls in the detachment direction due to its own weight, making it possible to unlock the lock and maintain a secure lock state. It wasn't something.

The present invention provides a magnetic lock that eliminates the above-mentioned conventional problems.

Examples thereof will be described below based on the drawings.

1 is a lock body, 2 is a lock plate fixed to the lock body 1, and a plurality of pinholes 3 are formed in this.

A plate 4 is fixed to the lock body 1 with a spacer plate 6 interposed between the bottom surface of the lock plate 2 and the spacer plate 6.

The spacer plate 6 closes the opening bottom of the pinhole 3 formed in the lock plate 2, making the pinhole 3 a blind hole.

Further, a magnet 5 is embedded in the plate 4 in the same phase as the opening position of the pinhole 3.

Therefore, the lock plate 2, spacer plate 6 and plate 4 are all made of non-magnetic material.

On the other hand, a sliding body 7 for locking and unlocking is provided on the lock plate 2, and a block 8 made of a non-magnetic material is fixed to this sliding body 7.

A plurality of lock pins 9 corresponding to the pinholes 3 are provided in the block 8 so as to be slidable in the axial direction.

This lock pin 9 is made of a magnetic material such as iron that can be attracted by magnetic force.

Reference numeral 10 denotes a key plate that is moved toward and away from the block 8 based on a positioning projection 12.

A magnet 11 is embedded in this key plate 10 in the same phase as the lock pin 9.

The magnet 11 embedded in the key plate 10 has a stronger magnetic force than the magnetic force of the magnet 5 embedded in the plate 4.

Since the present invention has the above-described structure, by attaching the key plate 10 to the block 8 as shown in the figure, all the lock pins 9 are pulled out from the pin holes 3 attracted by the magnetic force of the magnet 11 of the key plate 10. The sliding body 7 can be slid in the unlocking or locking direction.

When the key plate 10 is released from the block δ at the locked position of the slider 7, the lock pin 9 is attracted by the magnetic force of the magnet 5 on the plate 4 side, engages in the pinhole 3 and maintains that state, and the slider This controls the sliding movement of No.7.

In this way, in this invention, a magnet with a smaller magnetic force than the key plate magnet is installed below the lock plate so that the lock pin is magnetically attracted to the pinhole side, so when the key plate is not attached to the block, the lock pin is actively attracted by the magnet, engages with the pinhole, and maintains that state.

Therefore, compared to the conventional method which engages with a pinhole by falling under its own weight, locking with a lock pin can be achieved more reliably.
Moreover, since the engaged state is held by a magnet, even if the lock pin is reversed, it will not come out of the pin hole due to its own weight, and unlocking is restricted unless a key plate is attached, making it safe. It has the advantage of having gender.

Furthermore, since the lock pin is not a permanent magnet but a magnetic material, there is no need to consider the direction of the magnetic pole when assembling it into the pinhole, making the assembling process very easy and inexpensive. It also has advantages.
