Description

Lock with key {Lock with non-rotatory key}

The present invention relates to a lock having a mechanism of a new operating principle, in which the door is automatically opened and locked by converting the insertion force into elasticity in the operation of inserting a key into the lock.

Conventional locks are that when the rotor controlled by a pin or plate tumbler can be released by rotating the key by inserting the key into the rotor, the door opening and closing device directly connected to the rotor is opened or locked by turning the rotor with the key. Known for its basic configuration. However, since the rotational control of the lock rotor is controlled by a thin pin tip or a low durability of the thin layer of the thin plate tip, the rotor can be turned with a strong rotational force, so that the door opening and closing device directly connected to the rotor is opened. There is a safety flaw.

Each time the key is inserted and removed, two complicated rotations must be made to rotate in one direction and then reverse to return to its original position.The direction in which the key is opened and locked is the opposite since the rotation direction of the key is opened and locked. There is a drawback of confusing the direction of key rotation, such as turning it backward if it is confused and not turned in one direction. In addition, since the key can be removed even when the rotation angle of the key is less than the rotation angle, there is a drawback that sometimes the door opening and closing device can be mistaken as a locked state by turning the key less. Therefore, to open and lock the door; Inserting, turning, turning, and pulling out the four movements must be repeated twice, so a total of eight movements cause confusion or illusion frequently. And because the upper surface of the rotor lower pin is hollow, the gap between the upper and lower pin joint surface is 0.2mm, and if the gap between the lower pin length is 0.5mm, the gap between the body, rotor, and key is 0.2mm. The difference between the rotationally controlled pin joint surface and the rotor circumference boundary is only 0.1mm, which reduces the key difference and easily opens it in an illegal manner.

Thus, the applicant of the present application to the patent registration No. 10-0228058 in order to solve the above problems to be used safely and simply, but the operation mechanism by the door opening and closing device is complicated and there is a problem of cost increase.

The object of the present invention is to solve the above-mentioned drawbacks of the prior art by strictly preventing the opening by a strong rotational force or other unjust means, the safety consisting of a mechanism of a new operating principle that is automatically opened or locked only by the operation of removing the key and then turning it out without turning. And easy to use locks.

It is a lock configured by installing a known repeater (Repeater) configured so that the input rod is directed to the rear of the slider so that the reverse operation is repeated in reverse rotation.

Preferred embodiments of the present invention will be described in detail with reference to the drawings.

The upper and lower pins 4 and 5 to control the slide of the slider to the slider 3 sliding back and forth to the upper surface of the body 2 and a plurality of pin holes drilled up and down concentrically on the body 2 in FIGS. The upper and lower pins 4 and 5 and the pin springs 6, which are joined to each other in a plane perpendicular to the pin axis, are arranged to be inserted, and the key tip is formed in the key passage 2a where the key 1 slides back and forth on the bottom of the body 2. Arranging the pushers 11 supported by 1a) and sliding back and forth:

In Figure 4, the flange of the lower pin 4 is the jaw of the lower pin 4 hole so that the lower pin 4, which the upper pin 5 is pushed down by the elasticity of the pin spring 6, protrudes at a predetermined length from the upper surface of the key passage 2a. (2b) and the tension springs (12) are arranged on the left and right of the flange (11a) formed at the rear end of the pusher (11) and the lever (13) installed on the left and right of the front end of the slider (3). 11a) Arrange the compression spring 16 between the back and the case 8:

The key 1a and the jaw 1b on the left and right sides of the key waist as shown in Figs. 6 and 7 so that the key 1 is raised and lowered from the bottom of the rear end of the key passage 2a are the rear end of the key passage 2a as shown in the first and second degrees. On the left and right of the bottom face of the jaw 2d and the key passage 2a, the face of the jaw 2c abuts each other at an inclined angle:

And a repeater 14, which is configured to move forward and reverse in the next cycle by being rotated back 90 degrees in the next cycle, to the case 8 so that the input rod 14a faces the rear of the slider 3. (C) a lock constructed by means of;

Referring to the operation of the lock of the present invention.

The upper pin 5 is inserted into the body 2 pin hole or the lower pin 4 is inserted into the slider 2 pin hole by the compressive elasticity of the pin spring 6 in the slider 3 in FIG. When the slide of the slider 3 is controlled in the front and rear direction from the upper surface of the body 2, the slider 3 is locked, and the lower pin 4 and the upper pin are raised by raising the lower pin 4 with the key 1 as shown in FIG. When the joint surface of (5) coincides with the boundary surface of the body 2 and the slider 3, since the slider 3 can slide back and forth on the upper surface of the body 2, the slider 3 will be in an open state.

In FIG. 2, when the key 1 is inserted into the key passage 2a by hand, the key 1 is pressed against the tip of the lower pin 4 so as to move backward while rubbing the bottom of the key passage 2a to the key tip 1a. As the tension spring 12 is stretched as the pusher 11 is retracted, the slider 3 is retracted by the upper pin 5 to retreat with the elasticity of the tension force between the pusher 11 and the slide 3 being increased. Reverse is impossible. At the same time, as the compression spring 16 installed on the rear surface of the flange 11a is compressed, the compression force for advancing the pusher 11 is increased. The raised elastic energy of the tension spring 12 and the compression spring 16 is the operating energy to open and lock the door opening and closing device described later. Just before the key tip 1a reaches the rear end of the key path 2a, the key tip 1a and the jaw 1b on the right and left of the key waist are the jaws 2d and the key path 2a at the bottom of the rear end of the key path 2a. While the inclined surfaces on which the jaws 2c abut against each other slide on the left and right sides of the front bottom surface, the key 1 is lifted from the bottom surface of the key passage 2a to be in close contact with the upper surface as shown in FIG. Therefore, as described above, the lower pin 4 is raised so that the joining surface of the lower pin 4 and the upper pin 5 coincides with the boundary surface of the body 2 and the slider 3, so that the slider 3 is removed from the body 2. It becomes slidable, and the slider 3 becomes an open state. At the moment when the slider 3 is opened as described above, the slider 3 is retracted by the raised tensile force of the tension spring 12 so that the input rod 14a of the repeater 14 is reversed. 14b) is also reversed by the same distance as the door opening and closing device is opened or locked as described below to operate the 1/2 stroke and at the same time the output rod (14b) is reversed to compress the spring (15). As described above, the pusher 11, the slider 3, and the repeater output rod 14b are moved backward from the operation of inserting the key 1 into the key passage 2a by hand, and thus the known door opening and closing is not shown. The operation of the device is referred to as "key insertion interlocking".

As described above, when the hand 1 is released from the key 1 inserted into the key path 2a as shown in FIG. 3 until the "key insertion interlocking" is completed, the flange 11a and the compression spring 16 are pressed. The pusher 11 is advanced, the flange 11a pushes the rear end of the slider 3, the slider 3 is advanced, and the key 1 is pressed against the tip of the lower pin 4 so that the key 1 is at the top of the key passage 2a. If you go down from 2nd as below, The slider 3 pushed forward by the pusher 11 advanced as described above receives the elasticity of the pin spring 6 as described above, and the upper pin 5 is inserted into the pinhole 2 of the trunk 2, thereby providing the slider ( 3) is locked and pushed by the pusher 11 to be advanced, and the key is removed from the key passage 2a. In addition, since the slider 3 is advanced, the output rod 14b and the input rod 14a are also advanced by the compression force of the spring 15, thereby completing the operation of opening or locking the door opening and closing device. As described above, when the user presses the key 1, the pusher 11, the slider 3, the key 1 are pressed by the compression force of the compression spring 16, and the output rod 14b is pressed by the compression force of the spring 14c. And the input rod 14a are advanced together so that the door opening and closing device is called "key shaft interlocking operation".

As described above, if the period between the key insertion interlocking and the key shaft interlocking is completed as one cycle, the operation of the input rod 14a reciprocating back and forth a predetermined distance also becomes one cycle and the coaxial output arranged on the opposite side is repeated. The door opening and closing device is interlocked with the operation in which the rod 14b is interlocked and moves forward only in one cycle and only reverses in the next cycle, or moves forward by 90 degrees and reverses by rotating 90 degrees in the next cycle. The operation which is opened in the cycle of FIG. 1 and locked in the next cycle is alternately repeated. However, as described above, all operations other than the repeater 14 and the door opening and closing device are repeated while the same operation is performed every cycle.

The operating energy required for "key insertion interlocking" is obtained from the force of inserting the key 1 into the key passage 2a by hand, and the operating energy required for "key interlocking interlocking" is obtained from the elasticity of the compression spring 16. However, the elasticity of the compression spring 16 is obtained by the retraction of the pusher 11 during the "key insertion interlocking" operation, and the retraction of the pusher 11 consists of the insertion force of the key 1 and the elasticity of the compression spring 16. All operations of the lock of the present invention are achieved with the key 1 insertion force, as it is obtained with the key 1 insertion force.

In addition, the operating energy required for "key traction interlocking" may be the operating energy of the appliance which is in a manner other than the compression spring 16, or electric energy. All energies by this energy are constant at every cycle and do not need to be increased or decreased. And, as described above, the control pin for controlling the slider 3, or the strength of the slider 3 has a durability corresponding to the constant elasticity of the tension spring 12 and the compression spring 16, the slider 3 is moved forward and backward It does not require high endurance, such as high-strength control pins or disks and rotors needed to control the rotational forces of conventional locks. That is, the force of the slider 3 sliding in the lock of the present invention does not exceed 2 Kgf due to the elasticity of the tension spring 12 and the compression spring 16 to control the slider 3 sliding on the upper surface of the body 2 The shear force of the upper and lower pins (4, 5) is 2 kgf. However, if the conventional lock rotor is forcibly inserted into the key passage with a tool installed at the left end of a 300 mm long iron rod and rotated with a 10 kgf force at the right end, the shear force of the 3 mm diameter control pin on the circumferential surface of the 12 mm diameter rotor Since 10 kgf x 300/6 mm = 500 kgf, 2 kgf received by the lock control pin of the present invention is slight. In the conventional lock, the shear stress of five control pins with a diameter of 3 mm is assumed to be 1/4 of the free-cut brass wire tensile strength of 30 kg / mm2, which is 30/4 x 3² x π / 4 x 5 ea = 265 kgf. Rotational resistance of the pin tip inserted at a depth of 3.5 ÷ 2 = 1.7 mm, which is poor at the shear force of 500 kgf due to an indeterminate external force, and the tip of the control pin is an average of 3.5 mm of the maximum depth inserted into the body and the rotor hole. Is weaker than the shear stress of 265 kgf.

In addition, since the joint surface of the upper and lower pins 4 and 5 for controlling the slide of the slider 3 in the lock of the present invention is flat, there is no gap, and the slider 3 slides in a state of being in close contact with the upper surface of the body 2. The gap of the interface does not exceed 0.1 mm, and the key (1) is in close contact with the upper surface of the key passage (2a) at the completion of insertion. Is less than 0.05 mm, so the minimum difference between the slider (3) interface and the joint surface of the control pin is 0.2 mm in the play and deviation range of 0.15 mm or less, and the allowable change range of the lower fin length is 2.1 mm. Harpin length type r which can be wrong length is 2.1 ÷ (0.15 + 0.2) = 6 types, so key difference nr of lock having pin n of 8 rows is 8 ⁶ = 262,144 types. Conventional rotor harpins have a total clearance of 0.2 mm between the rotor and the body with a clearance of 0.1 mm, and a clearance of 0.1 mm between the key and the body, the keyway, etc. Since the minimum difference between the electronic interface and the junction of the control pin is 0.1 mm and the allowable range for changing the length of the lower pin is usually 3.5 mm, the type of lower pin r that can make the lower pin longer is 3.5 ÷ (0.4 + 0.1) = 7 types Therefore, the key type of a cylinder tablet having five rows of pins n is 5 ⁷ = 78.125. Therefore, about 250,000 kinds of high key types as in the above embodiment of the present invention can be obtained by the plane of the control pin joint surface, the close sliding of the body 2 and the slider 3, and the key 1 and the like. The close contact with the upper surface of the key passage 2a reduces the clearance and clearance.

The present invention is a safe lock that can not be opened unnecessarily due to excessive force or picking from the outside because only the key path is inserted into the lock as described above and all the active parts are warningly built. In other words, in the conventional lock, the rotor is inserted into the key and the mechanism is opened and locked directly connected to the door is opened by rotating the rotor unjustly, but the lock of the present invention is opened and locked by the key and the door is locked and locked It is a safe lock that cannot be opened illegally from the outside because the mechanism is separated and built in to warn. In addition, the door is automatically opened and locked only by inserting the key into the lock and then removing it without turning. It is convenient to use. . In addition, since the mating surface of the slide control pin is flat, it improves the quality of the key type and improves safety compared to the conventional rotary type.
