-corresponding to the particular pivotal position of described finger piece, the position of above-mentioned at least one aspect code part is arranged in selected code level place of the vertical code level of a predetermined number and is arranged in the selected lengthwise position place of predetermined number lengthwise position.
Background technology
Compare with the lock and the key system of the finger piece of pivot pivot on pellet shot from a slingshot with traditional rotatable pellet shot from a slingshot (tumbler) that do not have, this lock ﹠ key system of being known by above-mentioned United States Patent (USP) (Bo Wid é n) provides very high level of security.Can realize a large amount of code combinations, and lock is difficult to pry open or control.Each pellet shot from a slingshot can only be seen a part in lock core groove, and their correct lifting and pivotal code positions be can't see from passing the lock core groove inspection.Therefore, concrete code position can not be only from the observation lock core groove or even by determining with the tool detection finger positions.
The aspect code of the key piece waveform spigot surface of known key part (being sometimes referred to as side key tooth) all partly is made of concave surface, described concave surface partly has two acclivitous surface portions, and two acclivitous surface portions abut against on vertical both sides smoothly.These concave surface parts can be positioned at the many predetermined height in key piece side.More precisely, the highest vertical height that is used for the aspect code part will be positioned at the vertical height place partly lower slightly than side material district topmost, topmost the cutting of part place forms described waveform spigot surface in above-mentioned side material district, so that place the vertical extent size of adjacent two sloping portions.This typical prior art key is shown in Figure 28.
Concerning a kind of code structure, the aspect code part possible number relevant with concrete side locking pellet shot from a slingshot relates to the various combination that many predetermined vertically height and many and side lock the relevant lengthwise position of pellet shot from a slingshot.A kind of commercial use in the canonical system in many years, the side tumbler number be 5 (except 6 be positioned at the center with the pellet shot from a slingshot of top edge collaborative work key piece).The side material district that forms waveform spigot surface or side key tooth in the cutting of key piece side has a smaller height (perpendicular to the longitudinal direction of key piece), 2.0mm (about 0.080 inch) according to appointment.Therefore, have only a limited number of vertical high number of degrees to put, clearly distinguish simultaneously different codes again, two height that calculate from the key piece bottom margin especially respectively, 0.60mm (0.024 inch) and 1.20mm (0.048 inch).
These different height are relevant with the particular pivotal position of associated side locking tumbler finger.In used before this embodiment, have two with the corresponding vertical height of each pivotal end position of finger piece (in angle of pivot under+15 ° and-15 °) and two other with the corresponding height in medial pivot position (being 0 ° in angle of pivot locates), each other height is higher slightly than the height of at first mentioning respectively simultaneously, for example 0.90mm (0.036 inch) and 1.50mm (0.060mm).Why the vertical highly a little higher than pivotal end position angle place of 0 ° of angle of pivot place code section those vertically reasons of height be that difference or phase mutual edge distance between the adjacent pivot position are too little, so that can not provide obvious differentiated code.When vertical height and lengthwise position not simultaneously, it is bigger that difference becomes.
Therefore, in the foregoing description, each side locking pellet shot from a slingshot, 6 possible codes are arranged, that is
-corresponding to different two code sections vertically highly locating of place ,+15 ° of angles pivotal end position,
-corresponding to different two code sections vertically highly locating of place ,-15 ° of angles pivotal end position, reach
-corresponding to two code sections at the high slightly vertical height of the difference place of medial pivot position,
Each side locking pellet shot from a slingshot is formed 6 possible code sections altogether, perhaps add up to 6
5=7776 different combinations.
Certainly, ideal situation is further to increase this than higher number of combinations.Yet, the very standardization of the size of various keys, and also adapt to existing manufacturing equipment.Therefore, unique possibility is seemingly or with each vertical arrangement more mutual close highly, this means that the vertical distance difference between each the height level that compresses like this is too short, less than 0.50mm (0.020 inch), or use different pivot positions more than three, yet this also is infeasible because with this change obtain vertical poor very little.
Summary of the invention
With respect to this background technology, main purpose of the present invention provides and a kind ofly saferly prevents copy key or pry open lock and a kind of lock and key system that has bigger quantity may code combination is provided, and the overall dimension of lock and key in the maintenance system simultaneously.Another purpose is the manufacturing that can highly control key and key billet, thereby the user of lock and key system can think very assertorically that specific key is unique and can not be duplicated by unwarranted people.
Cylinder lock and key system with characteristics described in the claim 1 have been realized these purposes.Therefore, except the previous used vertical code level number of ratio in this lock and key system, the present invention also provides a kind of extra code level, described extra code level is positioned at the platform surface (shelf surface) of its longitudinal extension and locates, that is being positioned at the coboundary place in side material district, waveform spigot surface or side key tooth are formed on the described border in the cutting of place, key piece side.Because this extra code level, number of code combinations will increase greatly, and in above-mentioned example, each side locking pellet shot from a slingshot is increased to 7 code combinations from 6 code combinations, if have a row under the situation of 5 side locking pellets shot from a slingshot, number of combinations is increased to 16807 from 7776.Recruitment is greater than one times of above-mentioned quantity, and 9031 extra combinations are provided, and perhaps increases bigger number in some instances even also.These additional combinations can be used in lock ﹠ key system in the future, therefore make the end users of system can control the manufacturing and the distribution of key piece.Like this, can keep very high safety and prevent copy key without permission, even also be like this for the system that uses these additional combinations.
Can also form new key to existing locking device cutting, new herein side code pattern will be included at least one additional code section at extra code level place.In existing locking device, the combination of cylinder side can come by using common and normal combination technique, that is by replacing existing pellet shot from a slingshot to change with a new pellet shot from a slingshot that is adapted at extra code level place work.Like this, conventional device can be easy to upgrading, so that utilize 9031 new combinations.
Invention thought is based on following intention, described vertical platform surface boundary on the side material district that holds side key tooth, also can be used as an aspect code part, although it can not provide two sloping portions of a contiguous recess, and it may neither limit the pivot position of relevant tumbler finger uniquely.For as above-mentioned United States Patent (USP) in describe in detail be positioned at below each is highly located and has two in abutting connection with sloping portion, therefore and limit the code section of a spill position, different aspect codes partly can be configured on the specific pivot position, but this different code configuration generally can not be used to not have the side code top segment of two adjacent sloping portions.Therefore however, this side code top segment is being unique aspect its vertical height, and a specific code can be configured on this side code top segment, and has nothing to do with concrete pivot position that relevant tumbler finger presents.
Yet, in fact verified, if its makes progress slip (and key piece inserts in the lock simultaneously) on the side code top segment of the surperficial part of platform of formation longitudinal extension the finger piece of a rotatable side tumbler on a sloping portion, then it always is oriented in certain pivot position.When finger piece is climbed this and inclined the slope, finger piece will so lead, that is, its free end portion will be towards the free end or the tip of key piece.When finger piece moves to when being flat adjacent side code top section basically, finger piece will remain on this specific pivot location, even also be like this after the motion in finishing the lock core groove that key piece inserts lock.
What should consider is, when finger piece arrived a flat side code top segment, finger piece pivoted before and after will be at random.Yet, to compare with tumbler body itself, the quality of finger piece is very little.If around its axis rotation, then finger piece can only pivot tumbler body in relevant chamber.Even lock stands vibration or other random motion, there is not moment loading on tumbler body, to make its rotation yet.And, because tumbler body stands a power such as apply active force by spring, so there is certain rubbing action at the contact point place between the surface of the side code top segment of finger piece peace.This has just illustrated why in fact finger piece will remain in its ad-hoc location, that is remains in the pivotal end position of key piece tip.
Therefore, on flat side code top segment, definitely there is no need to be provided with any stop or maintaining body.However, in order to make provision against emergencies and in order to eliminate the incident that may not have that finger piece moves from its position, preferably in the flat side code top segment that forms geometrically with a kind of more shallow maintenance structure, above-mentioned more shallow maintenance structure must remain on finger piece in its pivot position, as long as key piece remains in the lock core groove of lock in its insertion position.
Extra code level can be used at any lengthwise position place along key piece, that is can be used for into many sides locking pellets shot from a slingshot of arranging any one.For each this side code top segment, the finger piece of associated side locking pellet shot from a slingshot will be located automatically and remain in the pivotal end position of key piece tip direction, and this was above illustrating.
Many preferred embodiments are stated in claims, and will be readily appreciated that by following detailed description.
The present invention can with other kind locking mechanism and key code decorative pattern, such as United States Patent (USP) 5,067,355 (Wid é n) or any other kind are used in combination.
For the extracode combination of bigger quantity is provided, in a lock and key system, can use rotatable and non-rotatable locking pellet shot from a slingshot simultaneously.By in some lock of system, the locking pellet shot from a slingshot of non-rotatable (but liftable activity) being used with rotatable and the locking pellet shot from a slingshot lifting activity, these non-rotatable locking pellets shot from a slingshot can be provided with and be suitable for moving away from the back-end location place of associated key sheet tip and at the finger piece of other code position place and side code top segment collaborative work, so that the maintenance high safety grade one.Thereby, can be extra code position of each pellet shot from a slingshot acquisition that is the 8th code position effectively.

The specific embodiment
In Fig. 1, show the cylinder lock ﹠ key that is included in according in the system of the present invention.Key 100 has grip portions 101 and key piece 102, and described key piece 102 can insert in the lock core groove 201 of lock 200.Extend on the longitudinal direction of lock core groove 201 in a lock core 202, above-mentioned lock core 202 rotatably axle journal is supported in the cylinder-shaped hole 203 in the lock body 204.
In this embodiment, key piece 102 has a top code pattern, described top code pattern place, edge thereon has and somely cuts part 103, described some row's locking pellet shot from a slingshot (tumbler) 205 collaborative works that cut part and be positioned at central authorities such as general type.
According to the present invention, key piece also has side code pattern, and described side code pattern has the aspect code part 104 of a Special Category, and disclosed in the aspect code of this Special Category part and the United States Patent (USP) that above-mentioned Wid é n is applied for those are identical.This side code pattern by one continuous generally be that the spigot surface of waveform forms, when key piece 102 inserts in the lock core groove 201 of lock 200, described waveform spigot surface and a row side locking pellet shot from a slingshot 206 (in this arranges 5) collaborative work.
Each all is installed in each side locking pellet shot from a slingshot 206 in the relevant chamber 207 (also seeing Fig. 2,3 and 4), is used for doing lifting therein and rotatablely moving.Each side locking pellet shot from a slingshot 206 all has a finger piece that crosses out 208, and when side locking pellet shot from a slingshot rotated in cavity 207, above-mentioned finger piece 208 arrived in the lock core groove 201, and moves pivotally.In fact, when key piece inserts in the lock core groove 201, the finger piece 208 of side locking pellet shot from a slingshot will engage with the spigot surface and the code section 104 of key piece, cause that therefore the lifting and the front and back of side locking pellet shot from a slingshot 206 rotatablely move.
Side locking pellet shot from a slingshot 206 locates to have a pair of groove 209,210 at the rear portion of its cylinderical surface (opposite with finger piece 208).One of them groove 209 can be seen in Fig. 2, and all two grooves 209,210 can be seen in Fig. 3.Between this two groove 209,210, bridging part 211 is arranged, described bridging part 211 is assembled in the corresponding recesses 212 in the side lever 213, and above-mentioned side lever 213 is as a locking device or protector.Side lever 213 is installed in the slotted recess 214 of outer cylindrical near surface of lock core 202.As shown in Figure 2, side lever 213 footpath upwards outwards is subjected to spring-loaded, so that normality is seated in the lock body 204 accordingly in the groove 215.In this position, side lever 213 will prevent effectively that lock core is with respect to lock body 204 rotations.
Yet, if when all side locking pellets shot from a slingshot 206 are all correctly located, then when the key of the key piece 102 that has correct code inserts in the lock core groove 201, bridging part 211 will be aimed at relevant groove 212 in the side lever 213, thereby the groove 212 of being correlated with can move inward diametrically.This moving inward can be implemented by the key sheet when being arranged in its complete insertion position when key piece, makes the flank of groove 215 that side lever is radially inwardly moved in the slotted recess 214.Now, lock core 202 can rotate in lock body 204, and certainly, this is with any other locking mechanism, also is released to condition as the locking pellet shot from a slingshot 205 of central row.
Therefore, when key piece 102 further moved in the lock core groove 201, because finger piece 208 engages with the spigot surface of key piece 101, side locking pellet shot from a slingshot 206 rotated front and back, and simultaneously, they also implement to move up and down.By a helical spring 216 effect, finger piece 208 is subjected to the power towards the below, and maintenance is slip joint with described spigot surface, and above-mentioned helical spring is installed into and is compressed between the upper surface and chamber 207 inner upper walls that the side locks pellet shot from a slingshot 206.
The side code pattern that has code position 104 is made of the spigot surface 105 that is waveform substantially, and described spigot surface 105 comprises the slope 106 of contiguous key piece 102 free end portions 107.When key piece 102 inserts in the lock core groove 201, slope will successfully engage with the respective finger 208 of each side locking pellet shot from a slingshot 206, and make side locking pellet shot from a slingshot 206 rotate and rise, and make finger piece 208 slide along wavy spigot surface 105 subsequently.In this case, finger piece 208 will followed wavy spigot surface 105 motions, also follow about each chamfered portion of spigot surface 105 simultaneously, that is open and fall the formula motion.It also will carry out front and back pivoting action or oscillating motion, thereby produce rotatablely moving of side locking pellet shot from a slingshot 206.
As shown in Fig. 3 and 4, a passage 217 is arranged, described passage 217 extends into the lock core groove 201 from the bottom of cavity 207, and the two side of this passage constitutes stop surface 218,219, described stop surface 218,219 will limit the pivoting action of finger piece 208 from a central plane towards both direction.In an illustrated embodiment, the position of stop surface 218,219 is definite like this, that is, limit movement to 15 °, that is in this embodiment, finger piece can swing in 30 ° angular range on each direction.
The 26S Proteasome Structure and Function of described lock ﹠ key is known in advance from above-mentioned document up to now.As shown in Figure 5, this key 100 (being equal to the key shown in Fig. 1) has code pattern 105, and described code pattern 105 has 5 code sections 121,122,123,124,125.Each such code section all is arranged in a following lengthwise position, described lengthwise position is corresponding with vertical distribution (Fig. 1) of side tumbler 206, when not excessive side tumbler 206 is pivoted to wherein any one angle end position, corresponding to the free end position of finger piece 208, can move a little distance.Code section 122,123,124,125 respectively form a kind of spill, described spill is between two adjacent inclinations or chamfered portion, and when key 100 inserts in the lock core groove of locking 201 fully, above-mentioned recess will help a corresponding finger piece is navigated in the specific pivot position.
As described in top patent, this will provide a kind of like this code, described code comprises a large amount of combinations, because this code all comprises different lifting positions and different pivot positions for each finger piece, that is, in the above-described embodiments, each pellet shot from a slingshot has 6 kinds of such combinations (if all 6 code sections all belong to this type, then adding up to 6 * 6 * 6 * 6 * 6=7776 kind code combination).
Yet, providing the code position number of increase and the safety of increase with prying open lock in order to prevent the copy key sheet, the spigot surface 105 that constitutes the side code pattern that has code section 104 forms in special mode in the present invention.This point is described for example, and referring to Fig. 5-9, described Fig. 5-9 shows in some code pattern through changing of key piece side edge.In these examples, one or more code sections of spigot surface 105 do not form the spill in abutting connection with two chamfered portions, but form a kind of side code top segment, and above-mentioned side code top segment forms the part on straight surface, top, a platform surface (shelfsurface) is represented on straight surface, described top, and this surface limits and forms the coboundary that will cut the material area that forms code pattern thereon.
Side code top segment length in a longitudinal direction can be so definite, that is, in the time of in the whole insertion lock core groove of key piece, the finger piece of associated side locking pellet shot from a slingshot can be pivoted to any angle position and keep simultaneously contacting with side code top segment.This is that flat side code top segment is represented with label 121 basically, shown in Fig. 5 and 10.
In the embodiment shown in Fig. 6 a and the 6b, the spigot surface that is roughly waveform comprises slope 106 in the free end office of key piece, and described waveform spigot surface comprises three " normally " recesses 221,223 and 225.But also comprise two side code top segment 222 and 224 of extending in the vertical.When relevant these side code top segment of finger engages, finger piece 208 (Fig. 2) can be taked the position (see figure 4) of any pivot or angle, and remains on simultaneously on the identical rise height.Yet as mentioned above, finger piece will automatically be positioned in the pivotal end positions of key piece free end or tip.
Therefore this rise highly itself forms a kind of special code, and this code is extra for concrete pellet shot from a slingshot existing " concavity codes ".Like this, except above-mentioned code position, also have at least one more possibility code, replace 6 code positions such as having 7 possible code positions.Therefore, in this concrete example, possible code combination sum will be 7 * 7 * 7 * 7 * 7=16807.
Generally, the sum of this side code top segment has 5 pellets shot from a slingshot and each pellet shot from a slingshot at this to have among the embodiment of 7 possible code positions can be zero, one, two, three, four or five.
Some additional embodiments is at Fig. 7 a, and 7b (has a side code top segment 324, has recess 321 in addition, 322,323 and 325), Fig. 8 a, 8b (also has a side code top segment 425, has recess 421 in addition, 422,423 and 424) and Fig. 9 a, 9b (have two side code top segment 521,525 and three recesses 522,523,524) shown in.
Side code top segment can form with several diverse ways.As shown in Figure 10 (and also having Fig. 1 and 5), it can form by surface portion 121 continuous by and straight longitudinal extension, and described surface portion 121 extends in parallel with the lower limb of key piece.
In addition also can, as shown in Figure 11, side code top segment can form a kind of relatively short bearing surface part 111, may adjoin shallow recess simultaneously.This relatively short surface portion will remain on pivotal end position with stop surface 218 (Fig. 4) butt to finger piece 208 (being positioned on the pellet shot from a slingshot 206).When inserting key piece in the lock core groove, the finger piece of side locking pellet shot from a slingshot will be rocked to described pivotal end position by being frictionally engaged of wavy spigot surface usually.
As mentioned above, when key piece inserts in the lock core groove fully, the finger piece of each side locking pellet shot from a slingshot will remain in these pivotal end positions.Therefore, come finger piece to be remained on correct position without any real needs by any inclined surface part or stop surfaces part.
However, one low clearance or 113 this guiding of realization or the supportings of retuse end portion slightly also can be provided, described end portion 113 at sweep 114 places smoothly in abutting connection with the main flat surface part 115 of described side code top segment, as shown in figure 12.
In Figure 13, a shallow recess 116 is arranged, described shallow recess 116 is positioned at an offset position place to the right, and is used on both direction the flexibly described pivoting action of backstop.
As shown in Figure 14, also have another kind of possibility to be, side code top segment comprises jut 118 upwards, and the described jut that makes progress 118 is formed by the recess part 117,119 that is positioned on two vertical side.
The possible position of code pattern and code section schematically illustrates in Figure 15.Here, clearly illustrate that, the finger piece 208 of each side locking pellet shot from a slingshot 206 can be in 7 different code positions, that is corresponding to the recess (three pivot positions, each pivot position are positioned on two vertical differing heights) and the above-mentioned extra top code position of 6 diverse locations.Three pivot positions of finger piece 208 illustrate with sectional drawing in Figure 15, and illustrate with phantom drawing in Figure 16-18.
Should note, for the concrete pivot position of finger piece in code position, the bridging part 211 that is positioned between two grooves 209,210 at the rear cylindrical place of side locking pellet shot from a slingshot 206 is in middle position, so that aim at the groove 212 in the side lever 213 (Fig. 3).Certainly, these grooves and bridging part 211 also should be positioned at following vertical position place, and described vertical position vertically highly is complementary with respective code position on key piece 102.Be suitable for and side locking pellet shot from a slingshot 206 ' (Figure 19) for a kind of in the side code top segment collaborative work at extra code level place, top, finger piece can be positioned at any pivoted position herein, groove at pellet shot from a slingshot rear surface place can form a kind of monolithic groove 209 ', described monolithic groove 209 ' can hold side lever, no matter and pellet shot from a slingshot 206 ' position of rotation how.
Certainly, these 7 different code positions or code section can be higher or lower number.Yet in the standard key of day a large amount of uses nowadays, shown embodiment is typical, and is a very real example.The key piece vertical with the key piece longitudinal direction vertically is of a size of about 8.6mm (about 0.34 inch), and the vertical extension size in side material district or highly be about 2.2mm (in 2.0-2.5mm interval) is cut the described spigot surface of formation in this side material district.Shallow recess height in Figure 11-14 is about 0.2mm (in the 0.15-0.25mm interval).
Even the side material district at key piece and formation waveform spigot surface vertically is of a size of above-mentioned situation, also still can further be increased to 8 to the code position sum of each side tumbler.This situation is shown in Figure 20-22.Here, this system comprises having the side tumbler 206 that can not rotate " (Figure 21) or the lock of 206 (Figure 22).These locks with one or more pellets shot from a slingshot that can not rotate (perhaps having very limited rotatory power) can be used in the system of the lock that comprises that other has only rotatable side tumbler.Like this, the 8th code position can obtain in the rearward end office of side code top segment.In Figure 20 (place, top enlarged diagram to the right), this rear end part is expressed as " 8 " (left side, top), and 7 code positions are expressed as " 1 "-" 7 " in addition.Code position " 8 " is corresponding to the section part 115 among Figure 12.
In same lock ﹠ key system, also can use to have pellet shot from a slingshot 206 as shown in figure 21 " lock.These pellets shot from a slingshot 206 " have finger piece 208 ", described finger piece 208 " be from start to finish from the base portion to the free end or head be 30 ° wide.This finger piece will with two code positions " 7 " and " 8 " collaborative work, and may be also with other code position or with these other code positions in some or all sloping portion collaborative work.
Because the code position " 8 " on the key piece is positioned at the highest or the highest approaching height place, thus during inserting in the lock, key piece have very little slope or some slopes also not to have, so that finger piece is directed to code position " 8 ".Here it is why must the pivot position of tumbler finger near position " 8 ", be limited in a limited pivoting angle (such as, less than 5 ° or 10 °), perhaps simply prevent its pivot in this position reason of (shown in Figure 20-22) fully.
Really, these specifically created tumbler finger can not pivot or just can pivot in a small angle range, and the lock core groove that they can be by double check lock (among Fig. 1 201) is observed.In order to stop, avoid or even make it can not determine accurately whether this pellet shot from a slingshot is placed in the lock or is placed on position in the lock, these pellets shot from a slingshot should be used in other code position selectively, as set on the throne or " 2 ", and may also be used in position " 3 ", use in " 5 ", " 6 " and " 7 " " 4 ".In the position " 3 ", " 4 ", " 5 ", in " 6 " and " 7 ", perhaps tumbler finger may so process its shape, even their key contact surface is towards the angle direction orientation of corresponding code position.
Although use code position " 8 ", may use with the pellet shot from a slingshot of corresponding coupling, but also still may form code position " 7 ", " 5 " or " 6 " (that is dual cutting) for any one pellet shot from a slingshot position (totally 5) locate cutting in contiguous code position " 8 ".Therefore this key can be opened a lock with code position " 8 ", has specific code position " 7 " but also can open another one, the lock of " 5 " or " 6 ".Adopt under this dual cutting situation, can provide some master keys certainly, described master key can be opened many different locks.
Shown in Figure 23-27, the platform surface of longitudinal extension defines the upper limit of described spigot surface, and can partly form one or more side code top segment, and the platform surface of above-mentioned longitudinal extension can form with diverse ways.In Figure 23, this surface 131 is positioned at the below of key piece 130 upper rims 132.In this case, platform surface 131 is held in the right angle with the central plane C of key piece.
In Figure 24, platform surface 141 is lower walls of lateral groove 142 in the key piece 140, and this lower wall central plane same and key piece is held in the right angle.
In Figure 25, key piece 150 has a bottom that broadens 151, and platform surface 152 is to protrude upward and the tongue of longitudinal extension or office, the upper end formation on lip limit 153 in this case.
In Figure 26, platform surface 162 is formed by the A lower side wall portion 162 of grooving 161 once, following bottom wall portion 162 is by incision, so that form an acute angle, and inside bottom towards groove, the shape of similar but more complicated 170 times groovings 171 of key piece is shown in Figure 27, and surf zone is represented with label 172 in this case.
Can change by those skilled in the art according to lock ﹠ key of the present invention system.As mentioned above, be not the lock in all pellets shot from a slingshot must be rotatable.Side locking pellet shot from a slingshot sum among one row can be different, such as a row two pellets shot from a slingshot or any desirable number are only arranged, even be higher than 5 pellets shot from a slingshot, and number of code levels also can arbitrarily be selected (if use more code level, then the height of described material area increases).The pivot position number of finger piece can be less than three such as having only two, perhaps more than three, such as four or five.The angle of pivoted end can be different.A side code pattern can be arranged on each side of key, and perhaps do not have top code pattern (among Fig. 1 103).In addition, the profile of key can change with many methods.
