Abstract

The present invention relates to a key structure which has a low unlocking rate and is determined by users and a matching use method. The structural improvement of the standard key of the prior art (the front end is cut) and a relevant improved method (the front end is cut to be inserted into the bottom of a key slot of a lockset) to realize the key structure. Thus, the present invention can greatly reduce the unlocking rate of the lockset of the prior art without changing the integral structure and the manufacturing technology of the lockset, the processing amount of a lockset key is slightly increased, and the cost amplification of the key is approximately 2%. The present invention is suitable for the improvement of most of locksets of the prior art.

Description

Key structure and supporting using method extremely low and that participate in determining by the user with the lock rate

Technical field:

The present invention relates to lockset technology and using method thereof.

Background technology:

At present, arrive all work units greatly, little of each family, even everyone, almost all can't do without for the sake of security every day, and come into contacts with lockset.Because nearly all in the world lockset is all produced by factory mass, and create key in batches by the limited mould of factory, it is very high with the lock rate, so the common saying road: the conventional main purposes of lockset is " anti-gentleman rather than anti-person of low position ".

Summary of the invention:

The present invention's purpose:

Proposition increases substantially the degree that anti-" person of low position " unblanks to the improvement of prior art key and using method thereof.

In order to realize above-mentioned the object of the invention, intend adopting following technology:

Design feature of the present invention:

On the architecture basics of existing various keys, it is characterized in that: can break disconnected arc line type boundary line off with the fingers and thumb but be provided with two at least in the amputation part, and, the boundary line is to depict by Sheet Metal Forming Technology to break disconnected flute mark off with the fingers and thumb, perhaps forms by the small round technology of punching out and can break disconnected round vestige off with the fingers and thumb.

Its supporting using method, even the purpose that preposition preparation matters that open the lock with the key and desiring reach:

A. an actual amputation that comprises head section zone in the key is at least partly broken off with the fingers and thumb from, break off with the fingers and thumb from the time could achieve the goal effortlessly by means of common tool usually.

B. with removing the remaining entity part in actual amputation part back in the key, with break off with the fingers and thumb from actual amputation partly head into and be preset on the key slot bottom position of lock, if necessary, can by means of adding plug thing or viscose glue it be located firmly again.

C. when having removed the remaining entity part in actual amputation part back in the key and insert the key slot of lock, the section of its front end matches with the above-mentioned section that has been positioned at the actual amputation part of key slot bottom surely, at this moment, can unblank.

---but the position (orientation and distance each other) and the shape (radian) of all boundary lines are to be determined by the production unit of key in the amputation part; And the range size of actual amputation part is determined voluntarily by the user.

The present invention's maximum characteristics compared with prior art are:

Especially key to break disconnected edge, cross section off with the fingers and thumb be the arc line type figure, this just causes very big difficulty to create condition for stealer also duplicates on the spot at short notice by arc line type (radian) sampling (comparing with the linear pattern figure or based on the broken line type figure of straight line) that is preset at lock interpolation trench bottom key amputation part when unblanking.

Especially key to break disconnected vestige off with the fingers and thumb be to depict by Sheet Metal Forming Technology to break disconnected flute mark off with the fingers and thumb; perhaps realize by the small round technology of punching out; this is just disconnected for allowing the user key can either be broken off with the fingers and thumb, can keep key to break the structural strength of the remaining main part of having no progeny (refer to: still exist on the key do not broken off with the fingers and thumb disconnected by stamped recess vestige or the small round of punching out) off with the fingers and thumb again and create condition.

Description of drawings:

Fig. 1 has illustrated a kind of the most frequently used on the key basis of prior art contour structures, realizes the first step of structure of the present invention, implements the embodiment of delineation processing technology that is:.

Fig. 2 has illustrated the present invention to enter the key contour structures after the user mode.

M: but the amputation part; N: actual amputation part; P: can not the amputation part; W: entity part (removed in the key actual amputation part after remainder); 1: head section zone; 2: two sections zones; 3: three sections zones; 4: the shank of the key; 5: the boundary line.

The specific embodiment:

The manufacturer of lockset only needs with reference to 5 places, boundary line illustrated in Figure 1, key with existing adapted in the lockset, depict at random by Sheet Metal Forming Technology: can could settle by oneself or entrust businessman to break the actual amputation part of key N off with the fingers and thumb disconnected flute mark by the user by means of two instrument vices, promptly provide: but the combined situation that can become each included relevant range of actual amputation part N among the key amputation part M of this adapted is selected for the user:

First zone combination is:

Actual amputation part N by " head section zone 1 " formation.

Second zone combination is:

Actual amputation part N by " two sections zones 2 of the head regional 1+ of section " formation.

The 3rd zone combination is:

Actual amputation part N by " three sections zones 3 of head section two sections regional 2+ of regional 1+ " formation.

Certainly, be that what complete manufacturers by key are determined on a case-by-case basis at the bottom of the above-mentioned combination road, zone.After the user takes key, but can in above-mentioned amputation part M, choose any one zone combination of wherein desiring amputation voluntarily and use two vices its amputation.---break off with the fingers and thumb too easily from also unrealistic, unless former design is exactly: but with desire to break off with the fingers and thumb from actual amputation part N be exactly whole amputation part M, that is: not to the user to desire to break off with the fingers and thumb from the range size of actual amputation part N any choice is arranged.

The scope of the actual amputation part N of Fig. 2 signal just in time is second above-mentioned zone combination.So, rest parts is exactly in this adapted key: the present invention after main part W when using.But this main part W just in time by Fig. 1 signal can not amputation part P with amputation part M in the two formation of " three sections zones 3 " part, and this constitutes, and is exactly after the present invention, final key contour structures in use.

At last, the user fills in the actual amputation part N (above-mentioned second zone combination) of Fig. 2 signal the bottom of key slot in the lock and implements dismountable location, also can implement non-removable permanent positioning by means of metal-to-metal adhesive.

After this, when the user uses main part W of the present invention to unblank and since main part W by the shape of truncation surface, coincide by the shape of truncation surface with the actual amputation part N that fills in key slot bottom, therefore, just can should lock unlatching according to the method for routine easily.

Otherwise, can imagine, if the thief tackles the lock that this class was moved " operation " slightly,, also be that the utmost point is difficult to achieve one's goal even if adopt key " master key group " attempt similar to open it steathily with this lock.Because:

1. the present invention's's (from breaking off with the fingers and thumb on the key from actual amputation part N) the similar key of being unrealized is can't insert fully the key slot of lock.

2. if all key brachymemmas (cost is considerable) in can " master key group " with similar key, make it can all insert key slot in the lock, but, add should be cut into man-hour which kind of section configuration (for example: the radian of section and the size variation rule rate) more be difficult to measure.

This shows that if additional again the technology of the present invention is implemented in the lockset of prior art, the pilferage difficulty of bringing to the thief will increase considerably, in the same lock rate that objectively is equivalent to reduce significantly lockset.
