Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a sliding bar type locking device in which a sliding bar is provided with a receiving part and the lock can be unlocked by pushing a long pin into the receiving part. It is related to.

(Prior art) Axial pin tumbler locks and ≠
The internal working mechanism and principles of locking devices such as radial pin tumbler locks are already well known, and a person with some skill can illegally unlock them in a relatively short period of time. could be easily invaded or approached.

(Problems to be Solved by the Invention) Therefore, the object of the present invention is to provide a highly safe sliding device with excellent resistance to incorrect interpretation, since the internal operating mechanism and principle are new, complex, and difficult to decipher. An object of the present invention is to provide a bar-type locking device.

(Means for Solving the Problems) Hereinafter, it will be explained using the reference numerals in the attached drawings. 1. The sliding bar type lock device of the present invention includes a key l, a lock body 2, and an outer side of the lock body 2. An outer member 6 integrally formed or integrally joined, a rotor 7 inserted into the interior of the lock body 2, and a single or plural sliding members inserted into the interior of the rotor 7 along the longitudinal direction. The head of the bar 8 is brought into contact with a locking groove 9 provided between the lock body 2 and the rotor 7, and the bar 8 is inserted into the elongated hole 3 provided in the rotor 7 along the radial direction of the lock body 2. a coil spring 11 inserted between the lock pin 10 and the bottom wall of the elongated hole 3 and applying force to the lock pin 10 in the centrifugal direction; and a coil spring 11 provided behind the sliding bar 8; a coil spring 20 that applies force to the sliding bar 8 forward; a cap member 12 that is integrally formed or integrally joined to the front surface of the rotor 7 and prevents the sliding bar 8 from protruding in the radial direction of the lock body 2; a passive protrusion 14 which is provided to protrude from the cap member 12 along the direction and which partially protrudes into the guide groove 13 formed between the cap member 12 and the outer member 6;
a small groove 17 that is formed in a cylindrical portion 16 formed on the back surface of the key 1 and that fits into a cylindrical portion 16 formed on the back surface of the key 1; The same number of protrusions 18 as the sliding bar 8 are provided inside the cylindrical portion 16, and the lock body 2 is provided on the sliding bar 8.
A receiving portion 4 is provided in the radial direction of the sliding bar 8, and the sliding bar 8 is pushed rearward by a projection 18, so that the receiving portion 4 of the sliding bar 8 and the bottom of the lock pin 10 are aligned.

(Function) In this sliding bar type lock device, the small groove 17 and the positioning protrusion 1
5 are fitted together, and the cylindrical portion 16 is connected to the rear end portion 12 of the cap member.
When 9111 is fitted into the guide groove part 13 until it contacts a, the split yt21 of the cylindrical part 16 is fitted with the passive protrusion 14,
The protrusion 18 in the cylindrical part 16 and the front surface of the slider /
0, and the receiving portion 4 of the sliding bar 8 and the bottom of the locking pin 10 are aligned on a straight line in the radial direction.

When the key 1 is rotated in one direction, left and right, a rotational force is applied to the passive protrusion 14, and the rotor 7 rotates in the same direction. At this time, the cam 9a of the lock ll19 formed on the inner peripheral surface of the lock body 2 pushes the head of the lock pin 10, so the lock pin 10 slides toward the center against the coil spring lla and moves inside. The end portion is pushed into the receiving portion 4.

As a result, the head of the lock pin 10 is completely accommodated in the elongated hole 3, and the rotor 7 becomes fully rotatable and unlocked.

On the other hand, when the key l is rotated in the opposite direction for locking, force is applied to the passive protrusion 14, and the rotor 7 rotates in the same direction accordingly. When the rotor 7 returns to its original setting position, the elongated hole 3 and the locking groove 9 are aligned, and the lock pin 10 receives the force of the coil spring 11 and slides in the centrifugal direction to separate from the receiving part 4.

In this way, when the lock pin 10 and the receiving part 4 are disengaged and the fit is pulled out, the sliding bar 8 is pushed forward by the force of the coil spring 20, and the sliding bar 8 is pushed forward by the force of the coil spring 20. The front end comes into contact with the cap member 12 and locking is established.

(A Example) In the illustrated example, the screw-shaped passive protrusion 14 fixes the camping member 12 to the a-button 7, and the outer member 6 is fixed to the lock body 2 by the screw 5. A long hole 22 is provided in the center of the rear end of each sliding bar 8 along the longitudinal direction. The front end of the slide pin 19 inserted into the coil spring 20 is inserted into the rear part of the elongated hole 22, and the rear end of the slide pin 19 is inserted so that the slide pin 19 is parallel to the longitudinal direction of the lock body 2. It is fitted and fixed in the small front hole 23 of the rear end portion 7a of the rotor. When unlocking, when the sliding bar 8 is pushed backward by the projection 18 of the fit, the front end of the slide pin 19 is pushed deeply into the elongated hole 22.

When locking and unlocking, the receiving part 4 and the lock pin 10 must be aligned, so when the receiving part 4 is formed into a small hole shape as in the illustrated embodiment, the sliding bar 8 cannot rotate. provided that. Therefore, in this embodiment, a quarter cylinder was used as the sliding bar 8, but the cross-sectional shape of the sliding bar 8 is not limited to this, and may be square or the like. still,
This receiving part 4 can also be a slit groove in the transverse direction of the sliding bar 8.

When the receiving portion 4 is formed by an annular groove on the outer circumferential surface of the sliding bar 8, the sliding bar 8 can also be formed into a rotatable shape such as a round bar.

When a plurality of sliding bars 8 are used as in the illustrated embodiment, the lengths of the plurality of protrusions 18 are set to have different lengths in order to create a large number of different keys and to make unauthorized unlocking more difficult. is desirable. Further, when a plurality of sliding bars 8 are used, a partition member can be provided between the sliding bars.

Furthermore, by providing a plurality of receiving portions 4 along the length of the sliding bar 8 and locking/unlocking a plurality of lock pins 10 thereto, more key errors can be obtained, and unauthorized unlocking can be further reduced. It becomes difficult.

In the above embodiment, the locking groove 9 formed on the inner circumferential surface of the lock body 2
is a rectangular groove that opens toward the outer circumferential surface of the rotor 7 and has a triangular prism cross section and has two inclined cam surfaces 9a, but this can be changed to other cross-sectional shapes such as a semicircular groove. can. Further, in this example, the head of the lock pin 10 is formed into a semicircular shape, but this can also be changed to other shapes such as a conical shape.

(Effects of the Invention) As described above, in the lock device of the present invention, first, the slide/ 10 and the receiving part 4 of the sliding bar 8 are aligned, and then when rotational force is applied to the rotor 7, the receiving part 4
The lock pin 10 is unlocked through a two-step process in which the inner end of the lock pin 10 is pushed in and the rotor 7 is allowed to rotate. Since the force is applied in the direction, it is difficult to determine when the receiving portion 4 and the lock pin 10 are aligned. As described above, the sliding bar type lock device of the present invention has a new and complicated operating principle and is difficult to decipher, so it is resistant to unauthorized unlocking and has higher safety than various conventional pin tumbler locks. It has the following.
