Abstract

A method for unauthorized unlocking of code unit devices of a lock variety by manipulating coding elements is largely performed all over the world. This practice also relates to unauthorized detection of worksites of dividing dials having a digital mark up with numbers and symbols, by means of visual methods. The inventive method makes it possible to exclude a manipulation for obtaining signals perceptible for aural and touch reception which can be used for the unauthorized unlocking of code units by means of blocking an alternate access to code elements accompanied by blocking a riegel, and also by using the digital mark up having neither numbers no symbols which place the dividing dials in an operative position using signals perceptible for organ of touch only.

Description

The method that stops undelegated unlocking of code unit lockType device

Technical field

The present invention relates to locking device, and be target to stop undelegated unlocking of code unit lockType device.

Background technology

The code device of lockType has two main structural members to interact with each other usually, and just be encoded an element and an encoder element accordingly, promptly are a locking bar and a pinning.

United States Patent (USP) 5024071 discloses a kind of code unit, and wherein the code pinning is placed in some holes.The existing shrinkage pool (hole) that vacation is effectively also arranged of these pinnings.In addition, this device comprises that has a locking bar that radially stops hole (radial stop), the cross section of locking bar corresponding to the shrinkage pool profile of the interactional code pinning of locking bar.But this device is attacked by the undelegated release of following mode easily: need only the signal that occurs when passing through to use the code pinning to change (search) with respect to locking bar, find out the hole of the work of code pinning.This locking bar can move in existing back seat (gap), and the sound that occurs in moving is easy to be heard.

The method (Russ P 2135719) that a lockType device of the undelegated release of a kind of well-known prevention is arranged.This method has significantly reduced the probability that these signals occur.When code pinning and locking bar interact and when mobile, these signals occur.This method directly contacts with locking bar up to them based on preventative pinning code pinning.The one big defective of the method is that the possibility of this code unit of unauthorized release appears and be used in signal.When locking bar stop that hole and code lock nail joint are touched the time, these signals will occur, wherein the code pinning moves to always and is prophylactically pinned.

As everyone knows, the code unit of lockType device uses rotating disk to increase the quantity that may make up.For example, in known safety lock, use rotating disk (Russ P 2083786 and 2002928).All distortion of rotating disk all have the discrete markers of distinct symbols (numeral, letter etc.), easily rotating disk is set to the operating position.A defective of this method is the possibility that the operating position of rotating disk is arrived in visual detection, thereby has reduced the property decoded of the code unit of lockType device.

Summary of the invention

A target of the present invention is the possibility that the signal of appearance makes a lockType device of unauthorized code unit release when eliminating by use code pinning and locking bar interaction.

Another target of the present invention is to eliminate the possibility of the operating position of visual detection rotating disk, and wherein said rotating disk makes undelegated unlocking of code unit lockType device become complicated.

In following method, realized first target: provide the pinning that locking bar is moved when being unlocked by the intermediary element between code pinning or code pinning and locking bar, and the locking bar that allows to be unlocked moves the intermediary element that makes between code pinning or code pinning and the locking bar and is lockable, not only stop the interaction between any other intermediary element between locking bar and code pinning or code pinning and the locking bar, also stoped the possibility of hearing above-mentioned signal.

In following method, realized second target: provide the do not have any symbol discrete rotating disk mark of (numeral, letter etc.).When the rotation rotating disk signal occurs and only felt by tactile organ, realize that by the rotating disk mark of counting a predetermined number since a fixing mark rotating disk is set to the operating position.For obtaining such signal, in the hiding sightless part of rotating disk, special configurations is arranged.When rotating disk forwarded some angles to, this configuration provided desirable signal.This signal only felt by tactile organ (finger), and is used to count the rotating disk mark and is set to the operating position with rotating disk.

The specific embodiment

Fig. 1 shows when locking device is lockable, the contact diagram of code unit.Simultaneously, locking bar 1 is not blocked device 2 and pins, and can move freely in an existing gap, but latch 5 refusals enter the hole 4 of placing code pinning 13.The method has been got rid of the possibility that mobile pinning makes them contact with locking bar, side by side except generate and hear the shrinkage pool that is used for working on the undelegated detection pinning the possibility of signal.

Fig. 2 shows the reverse position of code unit.This code unit is become this position in the following manner: the mobile latch 5 of a control device (not illustrating among Fig. 2) is (in Fig. 2, this latch moves to right) to allow to enter hole 4, block device 2 (using a plane inclined 6 and a restraint spring 3) is set simultaneously on the plane 7 of latch 5.As a result, block device 2 enters a ring groove 10 of locking bar 1, has pinned moving in its own existing gap between code pinning 13 and locking bar 1 like this, and described gap is greater than the gap of the block device 2 in the ring groove 10 of locking bar 1.This has just got rid of the appearance of signal of the unauthorized code unit release that is used to the lockType device and the possibility of use.

For necessity operation that the run time version unit pins or release is required, should use key 11 near latch 5.Simultaneously, the code spike 12 of key 11 is placed in the hole 4.Contact diagram illustrated in figures 1 and 2 is corresponding with the code unit on the close position.On this position, locking bar 1 is moved to the left side, and block device 2 can enter ring groove 10 and move on to the right to allow latch 5, so that the chance of shifting bond(s) 11 to be provided.When code unit during, provide second ring groove 10 (among the figure left side that) at open position.But, be used to pin in the code unit of safe locking device, in order not move this key during at open position, do not provide this second ring groove (among the figure left side that) at code unit.

For realizing the method, can use different modification according to the structure of code unit and locking device.These modification are themes of engineering development from now on.For example, Fig. 3 illustrates locking bar and can be blocked device 2 and pin, and block device 2 is started by solenoid 9, and solenoid links to each other with a button, has only when latch 5 during in some certain location, and this button just works.

Fig. 4 schematically shows a rotating disk 14 that has discrete markers on the visible part 15 of its structure.Described discrete mark does not have the symbol and the location of rotating disk mark.A hidden parts 16 of rotating disk 14 has a pit 17 and one and has 19 cylinder 18 with spring 20 interactional circles.Cylinder 18 (is not shown among Fig. 4) under certain situation to be placed in the groove.In such cases, a fixing mark is also arranged on visible part.

Operating process is as follows: when rotating disk is forwarded to some angles, 19 of the circle of shrinkage pool 17 and cylinder 18 contacts, so produce the signal that an energy is arrived by doigte, and this signal is used to begin to count from fixation mark 21 the rotating disk mark of a predetermined number, so that rotating disk 14 is set to the operating position.

Fig. 5 its structure visible part 15 on schematically show another kind of rotating disk 14.The discrete markers of this rotating disk 14 is without any symbol.So hidden parts 16 has around the rotating disk circumference shrinkage pool 17 to fix the position (diameter of shrinkage pool 22 is bigger than other shrinkage pool) of rotating disk mark and one and spring 20 interactional beads 23.This bead 23 (is not shown among Fig. 5) under certain situation to be placed in the groove.In such cases, a fixing mark 21 is also arranged on visible part.

In such a way rotating disk 14 is made as the operating position: when rotating disk is forwarded to some angles, shrinkage pool 22 contacts with bead 23, so produce a signal, this signal is easy to be arrived by doigte, and the signal that occurs when being different from bead and contacting with other shrinkage pool 17.Described signal is used for beginning to count from fixation mark 21 the rotating disk mark of a predetermined number, rotating disk 14 is set to its operating position.

In other embodiments, shrinkage pool produces the signal that can be placed on the invisible rotating disk terminal surface.

This method provides the ability that prevents to come by different operations release without permission for the lockType device (especially in strongbox) with rotating disk.
