Description

[Detailed Description of the Invention] This invention is based on ``using an electromagnet and utilizing its electromagnetic force.
The present invention relates to an electric lock device that performs an unlocking operation.

Traditionally, this type of electric locking device has been used for security purposes such as doors and large safes, but all of them are large and heavy, so they are often used in portable attache cases, etc.
It could not be used for portable items such as suitcases, large bags, and handbags.

This is because when the size is reduced, the output of the electromagnet is lighter, and it is more likely to fluctuate when impact force is applied to the case, etc.
This is because there is a possibility that the impact will cause a crab lock movement.
This invention was made in view of the above circumstances, and each part,
It is an object of the present invention to provide an electric locking device that can reduce the weight of its members and can therefore be applied to the various types of portable cases mentioned above. That is, in the electric locking device according to the present invention, the locking operation of the hook is not performed directly by the output shaft of the electromagnet, but is performed by an actuating member disposed parallel to the output shaft. The elasticity and mass of the elastic bodies (springs) engaged with these parts are set so that these members do not move even if an impact force is applied in the direction of the operating punch or the output shaft.

The configuration and operation of the present invention will be explained below with reference to the embodiments shown in the drawings.

The drawing shows the implementation in a suitcase mirror device, for example.

A is the suitcase body frame, and B is the lid frame.

The main body case 1 of the electric lock device is fixed to the suitcase main body frame A, and the locking part 15 of the hook is installed on the lid frame B. The main body case retainer has a linear surface that coincides with the end surface of the main body frame A, and is formed into a concave shape 1' at the hook locking position, and the hook 2 protrudes from the closed portion thereof. The hook 2 is swingable around a pin 3 provided as a shield on the main body case 1, and an actuating member 5 is swingably engaged with the other end opposite to the locking side via the pin 4. Reference numeral 9 denotes an electromagnet attached to a base 7 fixed to the main body case, and its output shaft is displaced by electric power supplied from the battery 8 via a lead wire 23.

That is, the compression spring 10 is interposed between the flange part F of the output shaft 11 and the end of the electromagnet 9, and the output shaft 11
is normally urged to advance to the left, and is displaced against the elasticity of the compression spring 10 as shown in the figure by the operation of the electromagnet 9. This compression spring 10 is an elastic body for locking, as will be described later. By the way, as is clear from the drawing, the operating punch 51 is arranged such that the output shaft 11 of the electromagnet 9 and their axes are parallel to each other, and the small diameter portion 5' of the other end is slidably held on the flange portion 7F of the base 7. has been done.

5F is a flange portion fixed to the stepped portion of the working village 5, and a compression spring 6 is interposed between the flange portion 5F and the flange portion 7F of the base 7.

This compression spring 6 is an elastic body that urges the actuating member 5 to the left to unlock it. Reference numeral 5K denotes a defective portion formed on the operating punch 5, and one end of the restraining lever turtle 4 is locked to this defective portion 5K as shown in FIG.

The restraint lever turtle 4 is swingably attached to a pin 13 installed in a shield on the base 7, and a long hole is formed at the end of the lever, and the shield is connected to the output shaft 11 of the electromagnet 9 in the hole of the lever. The provided pin 12 is in penetrating engagement. As described above, the illustrated state is a state in which the electromagnet 9 is activated, the output shaft 11 is retracted, the restraint lever tortoise 4 is swung clockwise, and the restraint of the working punch 5 is released. It is shown in a state in which it is displaced to the left by elasticity and the hook 2 is activated to lock the key.

The stove 7 is always urged upward by a compression spring 19 interposed between the flange portion 21 of the locking piece housed in the case 15 and the case 15.

Similarly, 16 is a knob that can be slid onto the case 15, and the flange portion 20 and the case! 5 and is constantly biased outward by a compression spring 181 interposed between the two.

The flange portion 20 of the knob 16 is the flange portion 2 of the locking piece 17.
It engages the outer side of the turtle. The knob 16 is Z-shaped and has an operating device 16', as shown schematically in FIG. 4 from the side. The operation to perform locking in the above configuration will be explained.

Since the state shown in the turtle diagram is the unlocked state as described above, the knob 1
6 is pressed to lock the door, and FIG. 3, which schematically shows the locking operation by operating the knob 6, will be described. When the knob 16 is pressed, the flange portion 2 of the locking piece 1? is pushed through the flange portion 28, and the locking piece turtle 7 is pushed.
' Displace in the direction of the arrow and advance to the hook 2 side. When the locking piece vine 7 advances to the position shown in FIG. 3, the tip inclined surface 16S of the stub 6 comes into contact with the tip 2' of the hook 2. Therefore, when the knob bS is pushed further, the locking piece 17 is also displaced downward, and at the same time, the hook 2 swings counterclockwise and its locking part 2F is locked to the locking part 17F of the locking piece 17, and the lock is released. It is done. This locking causes the actuator 5 to be displaced in the direction of the arrow, resulting in the state shown in FIG.

Then, since the restraining lever blade 4 is constantly biased counterclockwise by the compression spring 101, the lower end of the restraining lever tortoise 4 is latched to the notch 5K of the operating mallet 5, and the operating punch 5 is in the locked state. Nobu Isamu 6 is reinstated. When the lock is to be unlocked from the state shown in FIG. 2, the switch 22 is activated to activate the electromagnet 9. The switch 22 is operated directly by inserting a key or by magnetic force. As the electromagnet 9 operates, the restraining lever 14 operates clockwise and disengages from the operating punch 5, resulting in the state shown in FIG. Through the above operations, the main body frame A and the lid frame B of the suitcase are connected and released.

By the way, in the electric locking device according to the present invention, the weight of each member is reduced, and the entire scale is made small and light. However, due to this light weight, each member is easily moved by an external impact, and this causes a locking action. Cheap. This invention should solve this problem by devising the structure of the electromagnet and the actuating village. Now ~ The output shaft 1 of the electromagnet is the direction in which the material is likely to fluctuate (slide).
1. When an impact force (shock) is applied in the direction of the center of the operating punch 5, the output shaft of the electromagnet generates a force in relation to its mass, which causes the elasticity of the compression spring 10 as an elastic body for the punch. to face.

Here, when the mass of the output shaft 11 is W, the elasticity of the compression spring 10 is W2, and the acceleration (4 values of impact) is g, then W. - When there is a relationship of g>W2, the output ball 11 moves in the direction of the center of the ball due to the impact, and a locking operation occurs.

However, the actuating village 5 is also arranged in the same direction as the output shaft 11 and is subject to shocks and therefore receives the force due to the shock.

That is, if the mass of the entire working punch 5 is W3 and the elasticity of the compression spring 6 is W4, then a force of W3·g will act on the working punch 5.

Therefore W.・The mass W of the output shaft 11 and the working village 5 is adjusted so that the following formula holds: g - W2 × W31g - W4
, W3 and the elasticities W2 and W4 of each elastic body, the movement of the actuating village 5 becomes faster than the movement (movement) of the output shaft 11 of the electromagnet due to impact, and the engagement state of the restraint lever 14 is disengaged. The biasing of the operating punch 6 in the ball direction becomes faster, the restraint state is maintained, and as a result, the locked state is maintained.

In other words, malfunctions such as unlocking due to impact are prevented. Specific examples of the electric lock device having the features of the present invention are as described above and illustrated, but several modified embodiments having the features may be mentioned.

First, the output shaft of the electromagnet and the parallel operating punch are engaged with each other, and the restraining lever that enables the restraint or release of the operating punch is not limited to the shape shown in the figure, but can also be a linear lever in combination with its notch. This can be achieved by

The illustrated example is one example of the locking relationship between the hook and the locking piece, and also the relationship with the knob, and many modifications may be made. The force to be supplied to the electromagnet can be supplied not only by a storage battery but also by an alternating current power supply, and the supply control method can also adopt means other than the illustrated switch.

The elastic bodies for locking and unlocking are not limited to compression springs, and their intervening positions are not limited to the illustrated examples. For example, if a leaf spring or the like is used, it is possible to further reduce the size. The engagement relationship between the operating punch and the hook is also not limited to the illustrated example. The electric locking device provided by the present invention is as described above in detail, and provides a small and lightweight locking device, so that it can be used for portable bags such as attache cases, suitcases, luggage bags, and handbags.
Furthermore, it can be widely applied to portable safes, desks, lockers, etc. 4. We provide an excellent locking device that does not malfunction even when subjected to shocks from various directions, regardless of its shape or light weight, and is restrained to prevent malfunctions even when shocks are applied in the direction of the output shaft of the electromagnet. It is something to do.
