Description

  The present invention relates to a security code lock for a door and a security door system, and more specifically, an inexpensive security code lock for a door that is excellent in security and can be operated from both outside and inside the room. The present invention relates to a security door system using a security code lock for an open / close door.

Recently, crimes such as empty nests have increased, and it is not uncommon to use a technique that opens doors such as sliding doors and entrances of locked windows in houses and the like to enter the building. For example, in the case of sliding doors, break the glass plate near the lock that is locked with a crescent lock, etc. to make an opening that can be inserted into the hand, and then insert the hand inward from there to put a crescent lock, etc. The method of unlocking is often used. Further, in the case of a cylinder case lock such as a door, the lock portion by the key can be opened relatively easily, and even when locked by a thumb turn, it is often opened by means of a thumb turn.
Thus, even if it is locked, the actual situation is that it is relatively easy to enter the room from the outside.

  In order to prevent intrusion into a building using various techniques including the above-described methods, many crime prevention goods have been proposed and are commercially available. One such security product is a PIN code lock. Many of the code number locks used to lock the door use electric means. For example, a code number storage means, an electronic key, and a receiving means for receiving a signal sent from the electronic key. "Electronic lock and electronic key" used (Patent Document 1), mechanical lock device for moving a lock means such as dead bolt with a key, collation means for collating personal information such as a personal identification number and fingerprint, and mechanical lock device A “composite lock device” (Patent Document 2) and the like having a stopping means for stopping the driving of the locking means have been proposed. Also, a code number lock called a digital lock, which is used to input a code number from a numeric keypad and can be used as an auxiliary lock, is also commercially available. Such a conventional code number lock is relatively expensive even for other types such as those designed mainly for main doors such as entrances.

  As described above, the empty nest is created by breaking a part of the glass plate of the sliding door to unlock the crescent lock, of course the key lock on the front door, and turning the thumb turn from the outside. Often invades. Therefore, for sliding doors, lock the knob part with a PIN code from the inside so that the crescent lock cannot be unlocked even if part of the glass is broken, and the PIN code lock on the entrance door. Locking is an effective security measure. However, since the password locks currently on the market are relatively expensive, it is too expensive to attach the password locks to all the doors facing the outside in ordinary households, so cheaper password numbers Locks are sought.

  The code number lock currently on the market is an electronic or sophisticated mechanical lock composed of many parts, and the price is high. In the case of an electronic type, a number input unit is required, and in the case of a mechanical type, a key type input unit is also required.

  The personal identification number lock includes a dial type lock in which a ring portion with a number stamped is turned with a finger to align the personal identification number, and is widely used as a lock for a bicycle or the like. Such a dial lock is unsuitable for an open / close door of a general house, and is rarely used. However, there is a dial-type code number lock proposed for a gate (Patent Document 3).

  FIG. 23 is a cross-sectional view showing a “dial lock” disclosed in Patent Document 3, in which (a) shows a locked state and (b) shows an unlocked state. This dial-type lock includes a shaft 111 on which a plurality of protrusions 112 are formed, and a dial plate 113 having the same number as the plurality of protrusions 112. At the time of locking, as shown in FIG. 23A, the projection 112 is positioned between the dial plates 113 to prevent the movement of the shaft 111, and at the time of unlocking when the dial plates 113 are aligned with the password. As shown in FIG. 23B, the projection 112 passes through the groove 114 formed in the dial plate 113 so that the shaft 111 can move.

  The dial-type gate lock disclosed in Patent Document 3 has the same basic structure as a lock relating to unlocking and locking as a dial-type lock used for bicycles and the like, and is entirely configured for a gate door. Yes.

  These dial locks cannot be used as PIN codes for entrance doors or sliding doors as they are. That is, unlike the case of the front door, it cannot be operated from both the outdoor side and the indoor side. Further, in order to further enhance the security effect, it is not a mechanism that can change the password as necessary, and it is difficult to change to such a mechanism.

  A dial-type lock that can change the password at any time has also been proposed (for example, Patent Document 4). The dial lock disclosed in Patent Document 4 is of the type used for bicycles and the like. Although not shown in the drawings, this dial type lock includes a combination shaft provided with a protrusion at a position corresponding to each dial plate, and a dial plate composed of a tooth plate, a combination ring and a number ring. The protrusions of the combination shaft pass through the grooves formed in the tooth plate and the combination ring. When changing the security code, when the groove of the tooth plate is in the position corresponding to the protrusion, the tear hole of the tooth plate corresponds to the unlocking position, and the number ring is rotated to the unlocking position to pivot the tooth plate. Move it away from the number ring. In this state, the personal identification number can be changed by rotating the number ring.

As in the example disclosed in Patent Document 4 above, several dial locks that can change the password are proposed. However, all of them are mechanically complicated, and are used as wire locks for bicycles, lockers for lockers and doors of vending machines, and can be applied to ordinary houses. It is not possible.
In addition, a “slide lock” (personal code lock) has been proposed that is intended to be installed on a truck cargo door, a building door, an outdoor gate, etc. (Patent Document 5).

FIG. 24 is a perspective view showing a slide lock disclosed in Patent Document 5. As shown in FIG. The slide lock includes a bolt 124 having a plurality of protrusions 126, a plurality of rings (dial plates) 128, and a casing 125 that supports the plurality of rings 128. The bolt 124 passes through the ring body 128 when the body 128 is positioned according to the password. Each ring body 128 is composed of an inner tubular portion and an outer ring portion having a reference numeral (not shown), and the positional relationship between the inner tubular portion and the outer ring portion is shifted. You can change your PIN.
The PIN code disclosed in Patent Document 5 has a structure in which the PIN code lock is incorporated on one side of the casing 125, so that it can be used for doors such as doors for operating the PIN code from both the indoor and outdoor sides. It cannot be used as a PIN code lock.

Generally, the personal identification number lock uses the personal identification number as a key and does not require a key, and therefore has an advantage that there is no fear of losing the key. However, since the personal identification number, particularly the personal identification number having a large number of digits, is a sequence of numbers, there is a drawback that it is difficult for an elderly person to remember, for example. In addition, there is a drawback that it may be forgotten if it is not used for a long time. Therefore, there is a difficulty in that the conventional code number lock is not always satisfactory in terms of ease of use.

A slit 12a, a panel plate 12b, an upper groove 12c, a lower groove 12d, and a frame portion 12e are provided, and each configuration includes a slit 11a, a panel plate 11b, an upper groove 11c, a lower groove 11d, and a frame portion of the outdoor panel 11. It is almost the same as 11e. The inside of the indoor side panel 12 (the side on which the upper groove 11c and the lower groove 11d are formed) is attached so as to face the intermediate frame 13. In addition, since the indoor side panel 12 is fixed to the indoor side such as a door, there is no fear of being destroyed by an intruder, and thus the strength as the outdoor side panel 11 is not required. Therefore, it may be integrally formed of a plastic material or the like.

  The intermediate frame 13 shown in FIG. 3B is disposed between the outdoor side panel 11 and the indoor side panel 12, and the lock that moves in a direction perpendicular to the slide plate 15 while the slide plate 15 is arranged. The member 14 is supported. Therefore, the intermediate frame 13 includes an outer frame 13a that opens on the outdoor panel 11 side and the indoor panel 12 side, and a plurality of partition plates 13b that partition the inside of the outer frame 13a substantially parallel to the side portions 13c and 13d on both sides of the outer frame 13a. And locking member support holes 16 formed on the side portions 13c and 13d on both sides of the outer frame 13a (refer to FIG. 4 for the locking member support holes on the side portion 13c side).

The intermediate frame 13 includes a number of slide plate accommodation portions 13e corresponding to the number of slide plates 15 by the partition plate 13b, and each slide plate 15 slides in the slide plate accommodation portion 13e in the vertical direction. It is supposed to be. The partition plate 13b has a size that allows the locking member 14 and its protrusion 14a to pass at a position corresponding to the space between the locking member support holes 16 provided in the side portions 13c and 13d of the outer frame 13a, or A sufficiently large opening (not shown) is provided.
The combination of the slide plate 15 and the locking member 14 in the intermediate frame 13 is as shown in FIG.

  The intermediate frame 13 is configured such that the slide plate 15 is accommodated in each slide plate accommodating portion 13e of the intermediate frame 13, and the outdoor panel 11 and the indoor side panel are in a state where the locking member 14 is disposed through the intermediate frame 13. 12 is arranged. Thus, in the assembled state, the upper elastic member 15h of each slide plate 15 is engaged with the upper groove 11c of the outdoor panel 11 and the upper groove 12c of the indoor panel 12, and the lower elastic protrusion 15i is also the same. Are respectively engaged with the lower groove 11 d of the outdoor panel 11 and the lower groove 12 d of the indoor panel 12. Further, an alignment knob 15a of the slide plate 15 protrudes from the slit 11a of the outdoor panel 11 and the slit 12a of the indoor panel 12, and the slits 11a and 12a project from the slits 11a and 12a to the end surfaces 15b and 15c of the slide plate 15, respectively. The indicated code 15d can be read.

  Since the code code lock 10 according to the embodiment is configured as described above, the position of the code code is determined by operating the positioning knobs 15a projecting on the respective surfaces from both the outdoor side and the indoor side. It is possible to combine. In addition, the slide plate 15 can be reset so that the password is not read by a third party during locking. Furthermore, unlocking can be performed with the same password on both the outdoor side and the indoor side. However, when the code code lock 10 is attached so that the slide plate 15 reciprocates vertically, the code code is arranged in the reverse order between the outdoor side and the indoor side. That is, the security codes arranged in the horizontal direction are reversed on the left and right sides of the outdoor side and the indoor side.

  As described above, characters other than numerals can be used for the reference numeral 15d written on the end faces 15b and 15c of the slide plate 15. For example, when there are five slide plates 15 and the end faces 15b and 15c are arranged in the order of row, row, row, row, or row as viewed from the outdoor side, for example, “ The password for the word "Osakafu" can be used. However, when the number of characters written on each slide plate 15 is small, the number of passwords selected is limited. Therefore, it is preferable that the number 15d indicated on the end faces 15b and 15c of the slide plate 15 is as large as possible.

  As shown in FIG. 2A, since the slide plate 15 is provided with the slide plate attachment / detachment opening 15g, the slide plate 15 and the locking member 14 are combined in the state shown in FIG. Even in the case where the slide plate 15 is moved, the slide plate 15 can be removed from the locking member 14 at a position where the slide plate 15 is lowered from the state of FIG. Since the indoor side panel 12 can be attached to and detached from the intermediate frame 13 or can be opened and closed, the slide plate 15 can be easily replaced. Therefore, the slide plates 15 can be rearranged. Furthermore, when several slide plates 15 having different written codes (characters) have been prepared, various PIN codes can be selected and changed by replacing the slide plates 15 with the necessary ones. It is.

  5A and 5B are perspective views showing an example of a slide plate reset mechanism in the code code lock 20 according to the second embodiment. FIG. 5A shows a state in which the opening / closing lid is opened, and FIG. 5B shows a state in which the opening / closing lid is closed. Indicates the state. The code lock 20 includes an opening / closing lid 21 that covers the outdoor panel 11 on the front surface of the outdoor panel 11. The opening / closing lid 21 serves as a drive source for resetting the password at the same time as protecting the indoor panel 11. In other words, the open / close lid 21 is a drive source that moves the slide plate 15 aligned with the password in association with the opening / closing operation so that the state aligned with the password does not remain. .

  As shown in FIG. 5, a rotation shaft 23 is provided on the side portion 21 a of the opening / closing lid 21 in the vicinity of the opening / closing shaft 21 b, and one end of the drive bar 25 is rotatably supported on the rotation shaft 23. The drive bar 25 is pivotally supported by a support shaft 24 fixed to the intermediate frame 13, and the other end side of the drive bar 25 is rotatably connected to one end side of the transmission bar 27 by a connection fulcrum 26. . The other end side of the transmission bar 27 is rotatably supported on the support shaft 22a of the reset plate 22. Although not shown, a similar mechanism is also provided on the back side of the intermediate frame 13 (left side toward the opening / closing lid). The reset plate 22 has a length substantially corresponding to the width of the intermediate frame 13 and is similarly supported on the side not shown. Further, a groove 13f into which the reset plate 22 is inserted is formed at the lower part of the intermediate frame 13, and although not shown, a similar groove is also formed in the partition plate 13b in the intermediate frame 13.

  As shown in FIG. 5A, the reset plate is lowered when the open / close lid 21 is opened, so that the slide plate 15 in the intermediate frame 13 can be freely reciprocated (up and down). Therefore, an operation for aligning with the password can be freely performed. As shown in FIG. 5B, when the open / close lid 21 is closed, the reset plate 22 is pulled up, so that all the slide plates 15 in the intermediate frame 13 are pushed up to the same position and reset. Therefore, the position of the slide plate 15 that has been aligned with the password, that is, the password is not known.

  In the case of the code locks 10 and 20, in principle, after the position is aligned with the code and unlocked or locked, the person who operates it always shifts the position of the slide plate 15 so that the code is not known. It is. However, it is necessary to consider that the operation may be forgotten. In the case of the code code lock 20, the position of the slide plate 15 is reset by closing the opening / closing lid 21 as described above, so that the slide plate 15 is not left as it is at the code code position. Safety is improved.

In the embodiment shown in FIG. 5, the opening / closing lid 21 and the reset plate 22 are separate, but the opening / closing lid 21 is a slide type, and the reset plate 22 is integrated on the back side of the opening / closing lid 21. There may be.
Further, an illumination mechanism (such as a light emitting diode and a battery) that is turned ON / OFF in conjunction with opening / closing of the opening / closing lid 21 may be attached to the back side of the opening / closing lid 21.
FIG. 5 shows an example of the reset mechanism of the slide plate 15. However, there are several mechanical and electrical mechanisms for the reset mechanism, and these types can be used.

  FIG. 6 is a perspective view showing an appearance of a code-backed code plate code code lock 30 according to the third embodiment. FIG. 7 is a perspective view showing members housed in the main body of the code code lock 30. (a) is a signed rotating plate, and (b) is a combination of the signed rotating plate and a locking member. It shows the state that was done. Further, FIG. 8 is a cross-sectional view of the code code lock 30 shown in FIG. 6, in which (a) shows a cross-sectional structure taken along the line VIIIa-VIIIa ′, and (b) shows a cross-sectional structure taken along the line VIIIb-VIIIb ′.

  As shown in FIGS. 6 to 8, the code code lock 30 is arranged in a cylindrical casing 31 having an outdoor opening 31 a and an indoor opening 31 b, and the casing 31. And a plurality of signed rotating plates (hereinafter abbreviated as “rotating plates”) 35 that rotate around a locking member 34 that is a central axis of the shaft and that has a symbol on the outer peripheral surface thereof. Further, when the plurality of rotating plates 35 are positioned according to the code, the locking member 34 is configured to be able to pass through the rotating plate 35 and move in a direction substantially orthogonal to the rotating plate 35. In the outdoor opening 31a and the indoor opening 31b of the casing 31, the outer peripheral surfaces of the plurality of rotating plates 35 are positioned side by side, and the rotating plates 35 can be manually rotated.

  The locking member 34 includes a plurality of protrusions 34 a arranged in a line, and the interval between the plurality of protrusions 34 a corresponds to the interval at which the rotating plates 35 are arranged. The protrusion 34 a of the locking member is the rotating plate 35. The movement of the locking member 34 is prevented by being locked by.

Each rotary plate 35 opens to a through-hole 35e through which the locking member 34 passes, and is located at a position corresponding to one of a plurality of reference numerals 35d provided on the outer peripheral surface 35b of the rotary plate 35 at equal intervals. The protrusion 34a of the locking member 34 passes through the unlocking opening 35f having a size through which the protrusion 34a of the locking member 34 passes and the position facing the unlocking opening 35f across the central axis of the through hole 35e. An opening 35g for unlocking is provided.
Since the code code lock 30 is configured as described above, the protrusion 34a of the locking member 34 is engaged with the rotation plate 35 that is not aligned at a position corresponding to the code number among the plurality of rotation plates 35. The movement of the locking member 35 is prevented.

  A part of the rotating plate 35 is exposed at the outdoor side opening 31a and the indoor side opening 31b of the casing 31, and an alignment knob 35c is provided on the outer peripheral surface 35b on which the reference numeral 35d of the rotating plate 35 is indicated. Is provided. Accordingly, by operating the alignment knob 35c with the fingertips on both the outdoor side and the indoor side, the alignment of the reference numeral 35d indicated on the outer peripheral surface 35b of the rotating plate 35 can be performed. .

  As shown in FIGS. 6 and 8, a locking member support hole 36 that supports the locking member 34 is formed in a substantially central portion of the side surfaces 31 c and 31 d of the casing 31. Further, a groove 36a through which a protrusion provided on the locking member 34 described later passes is formed in the locking member support hole 36 on the side surface 31c side. The locking member 34 is supported by two locking member support holes 36 provided on the side surfaces 31c and 31d of the casing 31 so as to stably reciprocate. Hereinafter, each member and the whole structure will be described in more detail.

  As shown in FIG. 7A, the rotary plate 35 is generally disk-shaped, and a plurality of alignment knobs 35c are formed on the outer peripheral surface 35b, and a reference numeral 35d is provided therebetween. It is written. The code | symbol 35d is described on the outer peripheral surface 35b at substantially equal intervals, and what kind of code | symbol may be used if it can be used for PIN codes, such as a number, an alphabet, a hiragana, a katakana. Since the rotary plate 35 has a relatively long outer peripheral surface 35b, all characters can be written for each type such as hiragana, katakana, and alphabet. In that case, passwords such as words and words composed of characters corresponding to the number of the rotating plates 35 can be arbitrarily selected and used.

  For example, in the case of alphabets, there are 26 letters A to Z. Therefore, if the diameter of the rotating plate 35 is 50 mm, the distance between the letters is about 6 mm. When the thickness of the rotating plate 35 is 5 mm, characters of a size that fits in a frame of about 5 mm in length and width are written. A character having a size of 5 mm in length and width can be read sufficiently.

  In the case of Hiragana or Katakana, if all characters are used, 40 characters from line A to line and line, 3 characters from line, line 1 character (wa) and " 47, which displays 45 characters and 2 symbols, such as “N”, ““ ”for muddy sound,“ ° ”for plosive sound, etc. are required. As described above, if the diameter of the rotating plate 35 is 50 mm and the thickness is 5 mm, the characters are approximately 3 mm in length and 5 mm in width. Since it can be read even with this size, the above 47 characters (including symbols) may be written on the outer peripheral surface 35b of the rotating plate.

  However, in that case, the opening widths of the unlocking openings 35f and 35g that open in the through hole 35e are narrowed, and the circumferential length of the protrusion 34a of the locking member 34 needs to be shortened accordingly. . For example, if the diameter of the through hole 35e is 25 mm, the opening widths of the unlocking openings 35f and 35g are about 1.7 mm or less. In order to widen the opening widths of the unlocking openings 35f and 35g, it is preferable to include two characters, for example, “A” and “I” in one character frame and display “A / I”. In addition, relatively frequently used characters, about 25 characters, may be selected and displayed.

  By performing the above-described character notation on the outer peripheral surface 35b of the rotating plate 35, words, words, and the like having the number of characters corresponding to the number of rotating plates can be used as the password. In the case of the alphabet, English words or Japanese written in Roman letters can be used as the secret code, and in the case of Hiragana or Katakana, Japanese words, for example, nouns such as “Agao” and “Konotori” "I was hatched", it is possible to make the personal identification codes conversation control word, such as "Hello". Of course, numbers can be used as passwords, but words are easier to remember, and it is highly likely that elderly people will accept passwords without resistance. Can be used.

  Further, on the rotating plate 35, as described above, the unlocking openings 35f and 35g having a size through which the protrusion 34a of the locking member 34 passes are opposed to each other across the central axis of the through hole 35e. Is provided. Assume that there is only one unlocking opening indicated by reference numeral 35f, and 27 alphabetic characters including hyphens are written at equal intervals on the outer peripheral surface 35b of the rotating plate 35. When the code of the position corresponding to the unlocking opening 35f is “A” of the alphabet, and this code is aligned indoors, the alphabet “L” is positioned in the alignment part on the outdoor side. That is, in this case, the same code cannot be used on the outdoor side and the indoor side.

  However, as described above, when the unlocking openings 35f and 35g are provided at positions facing each other across the central axis of the through-hole 35e, the interior side Even so, the unlocking opening 35f or 35g and the protrusion 34a of the locking member 34 can be aligned with the same password. That is, the same code can be used at the time of unlocking and locking both indoors and outdoors. Thus, even in the case of the code lock 30 using the rotary plate 35, by providing the unlocking openings 35f and 35g at positions facing each other across the central axis of the through hole 35e, respectively. An extremely large effect is obtained that the unlocking and locking can be performed with the same password on the outdoor side and the indoor side.

  As shown in FIGS. 7B and 8B, the locking member 34 is provided with projections 34a arranged in a line, and the interval between the projections 34a is the interval at which the rotating plates 35 are arranged. It corresponds. The number of protrusions 34a of the locking member 34 corresponds to the number of the rotating plates 34, and each protrusion 34a is positioned between the rotating plates 35 or outside the rotating plates 35 arranged outside. It has become. When the protrusions 34a of the locking member 34 are located between the adjacent rotating plates 35 or behind the rotating plate 35 with respect to the moving direction of the locking member 34, all the rotating plates 35 are aligned with the code. In other words, when the unlocking openings 35f or 35g of the rotating plate 35 are arranged in a line so as to correspond to the positions of the protrusions 34a of the locking member 34 (all the rotating plates 35 are shown in FIG. 7). In the state shown in (b)), the locking member 34 is movable in a direction substantially orthogonal to the rotating plate 35.

  On the other hand, when the protrusion 34a of the locking member 34 is positioned between the adjacent rotating plates 35 or behind the rotating plate 35 with respect to the moving direction of the locking member 34, at least one rotating plate 35 is a password. When not aligned with the code, the movement of the protrusion 34a of the locking member 34 is locked by the rotating plate 35 not aligned with the password, and the movement of the locking member 34 is prevented. Has been.

  As shown in FIG. 6, the rotating plate 35 is housed in the casing 31, and the outer peripheral surface 35 b of the rotating plate 35 is formed from the outdoor side opening 31 a and the indoor side opening 31 b of the casing 31. Is exposed, and the rotating plate 35 can be operated with a fingertip or the like. In the outer peripheral surface 35b of the rotating plate 35, the ratio of the exposed portion is about 1/6 to 1/4 in both the openings 31a and 31b, and about 60 ° to 90 ° at an angle based on the center. preferable. When there are too few exposed parts, it is difficult to rotate the rotating plate 35, and when there are too many exposed parts, a mechanism such as a support structure of the casing 31 is hindered.

  As shown in FIG. 6, the casing 31 supports the locking member 34 by the two locking member support holes 36 provided in the side surfaces 31 c and 31 d and supports the rotation of the respective rotating plates 35. Also have. That is, the rotating plate 35 is configured to rotate with the locking member 34 as the rotation axis. However, since the thickness of the rotating plate 35 is small with respect to the diameter of the rotating plate 35, the rotation is difficult to stabilize. For this purpose, as shown in FIG. 8 (a), support protrusions 31f are provided at positions corresponding to the space between adjacent rotating plates 35 in the circumferential direction inside the outer peripheral frame 31e of the casing 31, and the support protrusions 31f The side surface 35h of the outer peripheral portion of the rotating plate 35 is supported. The length of the support protrusion 31f (the length from the inner surface of the outer peripheral frame 31e of the casing 31 toward the center) may be increased as necessary when there is no problem with the thickness of the rotating plate 35.

  The rotating plate 35 is supported between the outer peripheral surface of the alignment knob 35c and the inner surface of the outer peripheral frame 31e in addition to supporting in the direction orthogonal to the rotational direction between the support protrusion 31f and the side surface 35h of the rotating plate 35. Thus, radial support may be performed.

  Since the casing 31 supports the locking member 34 and the rotating plate 35, it is preferable that the casing 31 has strength and is not easily destroyed by an intruder or the like. Moreover, it is preferable that the locking member 34 and the rotating plate 35 are also formed of a material having strength. Therefore, a metal material such as stainless steel or a high-strength aluminum alloy is suitable for the casing 31 and the locking member 34. In addition, high-strength engineering plastics may be used. Further, since the rotating plate 35 needs to have a certain level of strength, it is preferable to use the above metal material, engineering plastic, or a combination thereof.

Since the code lock 30 according to the third embodiment is configured as described above, the position of the code is adjusted by operating the positioning knob 35c of the rotating plate 35 from both the outdoor side and the indoor side. Is possible. Further, at the time of locking, the rotation plate 35 can be rotated and reset so that the password is not read by a third party. Also, unlocking can be performed with the same password on both the outdoor side and the indoor side. However, when the code code 30 is used sideways, the left and right order is reversed between the outdoor side and the indoor side.
FIG. 9 is an exploded perspective view showing the rotary plate 35 used in the code code lock 30. FIG. 9A shows a code ring, and FIG. 9B shows a support disk. The overall configuration of the rotating plate 35 is shown in FIG. 7A, and the cross-sectional structure is shown in FIG.

  The rotating plate 35 is constituted by a sign ring 38 and a support disk 37, and the sign ring 38 is slidably fitted to the outer peripheral surface 37 a of the support disk 37. The support disc 37 has a disc shape, and a through hole 35e through which the locking member 34 passes and unlocking openings 35f and 35g that open into the through hole 35e are formed at the center. As shown in FIG. 8, the thickness of the support disk 37 is smaller than the width (thickness) of the sign ring 38, and the protrusion 34 a of the locking member 34 enters between the adjacent support disks 37. It has become. A screw hole 37 c is formed in the outer peripheral surface 37 a of the support disc 37 at a position corresponding to the interval of the reference numeral 35 d written on the reference ring 38.

  The sign ring 38 has an alignment knob 35c formed on the outer peripheral surface 35b, and the sign 35d is shown at equal intervals. The code ring 38 is wider than the thickness of the support disk 37, and as shown in FIG. 9A, a recess 38a into which the support disk 37 is fitted is formed on the inner peripheral side. The code ring 38 is provided with through holes 38b at positions separated by a plurality of codes. The sign ring is fixed to the support disk 37 by passing a screw (not shown) using this through hole 38b and screwing it into the screw hole 37c opened on the outer peripheral surface of the support disk 37. Can be done. It should be noted that at least one through-hole 38b may appear in the opening 31a or 31b of the casing 31 when the rotating plate 35 is operated.

  Since the rotating plate 35 is composed of the above-described code ring 38 and the support disk 37, the positional relationship between the code ring 38 and the support disk 37, that is, the outer peripheral surface of the rotation plate 35 is removed by removing the screw. The positional relationship between the reference numeral 35d written on 35b and the unlocking openings 35f and 35g formed on the support disk 37 can be changed. Moreover, the positional relationship can be fixed with screws after the change. Therefore, the password set for each rotary plate 35 constituting the password code lock 30 can be easily changed.

10A and 10B are perspective views showing a rotating plate according to another embodiment, in which FIG. 10A is an example of an integrated rotating plate 35A, and FIG. 10B is a combination of the rotating plate 35A and a locking member 34. Indicates the state.
As shown in FIG. 10A, the rotating plate 35A is an integral type. In the case of the integral type rotating plate 35A, the side surface 35A-1 is a flat plate, the outer peripheral portion enters between the support protrusions 31f of the casing 31, and the rotation direction of the rotating plate 35A is supported by the support protrusions 31f of the casing 31. The support in the direction orthogonal to is performed. Thus, the rotating plate 35A has a simple structure. FIGS. 6 to 9 show examples of the rotating plate 35 that can change the password set for each signed rotating plate. However, when the number of characters written on the rotary plate 35 is large, the code set on each rotary plate 35 may not necessarily be changeable. In such a case, the price of the code code lock 30 can be further reduced by using the rotating plate 35A.

  FIG. 11 is a perspective view showing a rotating plate 35A according to still another embodiment. As shown in FIG. 11, in the case of the rotary plate 35A, the alignment knobs 35c are formed at irregular intervals with some reference numerals. It is only necessary that at least one alignment knob 35 appears in the openings 31a and 31b of the casing 31 when the rotary plate 35A is operated. Further, the intervals between the alignment knobs 35c need not be equal, and are irregular as described above. In the case where the alignment knob 35c is provided with a plurality of symbols and the intervals are irregular, as will be described below, it is very convenient for automatic reset of the rotating plate 35A after locking.

  FIG. 12 is a perspective view showing the configuration of the code code lock 40 according to the fourth embodiment. 13 is a perspective view showing the main body of the code code lock 40, FIG. 14 is a diagram for explaining the relationship among the movement of the opening / closing lid, the drive arm, and the reset bar, and FIG. 15 is the movement and alignment of the reset bar. It is a figure which shows the relationship with the motion of the knob for operation.

  As shown in FIG. 12, the code code lock 40 includes an open / close lid 41 that covers the outdoor opening 31a and the rotating plate 35A on the front surface of the outdoor opening 31a. The opening / closing lid 41 serves as a drive source for resetting the password at the same time as protecting the portion of the rotating plate 35A exposed to the outdoor side. In other words, the open / close lid 41 is a drive source that keeps the state aligned with the code by leaving the rotating plates 35A aligned with the code at random in conjunction with the opening / closing operation. Acts as

  The main body 30A of the code code lock 40 is substantially the same as the code code lock 30 according to the third embodiment. However, the rotating plate is of the type 35A shown in FIG. 11, the reset bar guide groove 44 is formed in the upper part of the side surfaces 31c and 31d of the casing 31A, and the drive arm support part 45 is formed in the upper part. The difference is. The drive arm support 45 is provided with a drive arm rotation shaft 45a.

  The opening / closing lid 41 has an opening / closing shaft 41a positioned near the upper end of the opening / closing lid 41, the opening / closing shaft 41a is fixed to a door or the like, and can be opened / closed in the vertical direction around the opening / closing shaft 41a. A connecting shaft 41b is provided below the opening / closing shaft 41a, and a slit-like connecting hole 42a formed on one end side of the drive arm 42 is fitted into the connecting shaft 41b.

  As shown in FIGS. 12 and 14, for example, the drive arm 42 is generally L-shaped as a whole, and has a L-shaped corner portion with a rotation shaft hole 42c and a slit-shaped connection portion with the opening / closing lid 41 side. A slit-like connecting hole 42b is formed at a connecting portion between the connecting hole 42a and the reset bar. The drive arm 42 is rotatably supported at a rotation shaft hole 42c by a drive arm rotation shaft 45a of the drive arm support 45 of the casing 31A, and a slit-like connection portion 42b is fitted to the connection shaft 41b of the opening / closing lid 41. ing. Further, the support portion 43a of the reset bar 43 is fitted into the slit-shaped connection hole 42b. The drive arm 42 is provided on both sides of the opening / closing lid 41, that is, on both sides of the casing 31A.

  The reset bar 43 is located above the rotating plate 35 and substantially parallel to the rotation axis of the rotating plate 35, and both support portions 43 a are passed through the reset bar guide groove 44, and further outside the drive arm 42. It is passed through the connecting hole 42b. Therefore, the reset bar 43 reciprocates along the reset bar guide groove 44 by the movement of the drive arm 42 accompanying opening / closing of the opening / closing lid 41.

  Next, with reference to FIG. 12 and FIG. 14, the relationship of the movements of the opening / closing lid 41, the drive arm 42, and the reset bar 43 will be described. Since the opening / closing shaft 41a of the opening / closing lid 41 is fixed to a door or the like, the position of the opening / closing shaft 41a does not move. When the opening / closing lid 41 is opened, the connecting shaft 41b of the opening / closing lid 41 moves substantially in a semicircle with the opening / closing of the opening / closing lid 41, as indicated by a dotted line in FIG. The drive arm 42 rotates around the drive arm rotation shaft 45a of the drive arm support 45 provided in the casing 41 as the connecting shaft 41b moves. That is, as shown in FIG. 14, the drive arm 42 rotates from the position (a) to the position shown in (c) via (b). Accordingly, the support portion 43a of the reset bar 43 that is passed through the connecting hole 42b of the drive arm 42 moves along the reset bar guide groove 44 as shown by a one-dot chain line shown in FIG. When the open / close lid 41 is closed, the reverse movement occurs.

  FIG. 15 is a side view schematically showing the relationship between the movement of the reset bar 43 and the movement of the alignment knob 35c of the rotary plate 35A. The locus of the end on the lower end side (positioning knob 35c side) of the reset bar 43 is indicated by a one-dot chain line. On the other hand, the locus of the top of the alignment knob 35c is indicated by a dotted line. Between the symbols X1 and X2, the alignment knob 35c is moved by the reset bar 43, and the alignment knob 35c outside X1 and X2, for example, at the positions of Y1 and Y2, moves even if the reset bar 43 moves. Will not be affected. That is, when the reset bar 43 moves from X1 to X2, the alignment knob 35c positioned therebetween is moved to the position of X2, and when the reset bar 43 moves from X2 to X1, , Moved to the position of X1.

  Here, the alignment knob 35c of each rotary plate 35A does not correspond to all the symbols, but is formed at intervals. Accordingly, the degree of rotation by the reset bar 43 is different for each rotating plate 35A. For this reason, since all the rotating plates 35 do not move in the same manner in the state where the password is set, the password is more difficult to understand.

When the open / close lid 41 is in an open state or a closed state, the reset bar 43 is positioned outside the X1 or X2, so that the rotating plate 35A rotates without being affected by the reset bar 43. It is supposed to be. In addition, after the opening / closing lid 41 is opened and the password is set, when the opening / closing lid 41 is closed, the alignment bar 35c positioned between X1 and X2 is moved by the reset bar 43, and the rotating plate 35A is moved. Since each rotation plate 35A rotates differently, it is not left in a state of being aligned with the code, and at the same time, the code is not known.
In the case of the code code lock 40 according to the fourth embodiment, an example of a mechanism for resetting by opening and closing the opening / closing lid 41 has been shown. However, there are several mechanical and electrical mechanisms for the reset mechanism. You can also use those types.

  FIG. 16 is a perspective view showing the outer appearance of the locking member used in the code lock according to the fifth embodiment and the protrusions of the locking member. The code code lock according to the fifth embodiment moves the locking member to the lock position (locking position) without aligning the rotary plates 35 and 35A with the code code when the door or the like is locked by the code code lock. It can be made to.

  The locking member 51 has a structure in which a locking member main body 52 and a protruding member 53 are combined. The protruding member 53 is incorporated into the hollow locking member main body 52, and the protrusion 53a is locked. It can freely enter and exit at the projection hole 52a of the member main body 52. That is, the protrusion member 53 is disposed in the lock member main body 52 at a position where each protrusion 53a corresponds to the protrusion hole 52a. The lock member main body 52 is provided with electrodes 52b and 52c, as shown in FIG. 16B, in the region where the projection hole 52a is formed and slightly on the end side thereof.

The protruding member 53 is supported so that the protruding plate 53 b can move up and down by two support bars 54, and the support bar 54 is located in the coil spring 55. A ferromagnetic material 53c such as iron or nickel is fixed to the bottom side of the projection plate 53b, and when the magnetic force acts, the projection plate 53b is drawn downward against the coil spring. ing. An electromagnet 56 is disposed below the ferromagnetic material 53c, and a magnetic force is generated in the soft magnetic material 56b by passing a current through the coil 56a. Therefore, when a current is passed through the coil 56a, the protruding member 53 is attracted, and the protrusion 53a is pulled into the protruding hole 52a.
The lead wires L1 and L2 of the coil 56a are connected to the electrodes 52b and 52c of the locking member main body 52, respectively, and power is supplied through the electrodes 52b and 52c.

  FIG. 17 is a perspective view showing the relationship between the power supply to the electrodes 52b and 52c and the movement of the locking member 51 in the code code lock 50 according to the fifth embodiment, and FIG. The position of the lock, (b) shows the state in which the locking member 51 is in the locked position. As shown in FIG. 17A, the brushes 57a and 57b connected to the power source and the switch are in contact with the electrodes 52b and 52c provided on the locking member main body 52. Here, although not shown, the switch is set to be turned on when the opening / closing lid (reference numeral 41 in the case of the code code lock 40) is opened and turned off when the lid is closed. Batteries such as are used.

  In the unlocked state shown in FIG. 17A, the electrodes 52b and 52c and the brushes 57a and 57b are in contact with each other. Therefore, when the opening / closing lid 41 is opened and switched on and electric power is supplied from the power source, the protruding member 53 is drawn toward the electromagnet 56 side, and the protruding 53a does not come out of the locking member main body 52. At that time, the locking member 51 can be freely moved to the locking position. When the locking member 51 moves to the locking position, as shown in FIG. 17b, the positions of the electrodes 52b and 52c are disengaged from the brushes 57a and 57b, and the supply of power is cut off. At the same time, the projection plate 53 is urged by the coil spring 55 to return to the original position, and the projection 53 c projects from the lock member main body 52. Each protrusion 53a enters between the rotary plates 35 and 35A, and the code code lock is locked.

  As described above, the code code lock according to the fifth embodiment can move the locking member 51 freely by opening the opening / closing lid 41 when locking. When locking, the rotating plates 35 and 35A can be locked without being aligned with the password, so that the locking operation is extremely simple. Further, in the locked state, the projection 53 a is not pulled into the locking member 51 simply by opening the opening / closing lid 41. Therefore, it is safe because it cannot be unlocked unless it is aligned with the password.

  Note that the mechanism for allowing the projection 53a to be pulled inward during locking is applicable to all rotary plate-type code locks, as well as the slide plate-type passwords according to the first and second embodiments. The present invention can also be applied to the code locks 10 and 20. Further, the mechanism for moving the projections in and out is not limited to the mechanism according to the fifth embodiment, and may be another mechanism.

  18A and 18B are perspective views showing a code code lock 60 according to the sixth embodiment. FIG. 18A is an exploded view showing members constituting the code code lock 60, and FIG. 18B shows a locked state. FIG. The code code lock 60 is a type that is manually operated from one side, and is a lock that is mainly used by being attached to the indoor side.

  The code code lock 60 is a front panel that houses and holds a code code key member 61 having a dead bolt 64, a key block 65, a hinge member 66, a code code key member 61, a key block 65, and a collar member 66. 62, and the back side is closed by a back panel 63 as necessary.

  A plurality of key block grooves 67 partitioned in parallel by a partition plate 61 a are formed in the password key member 61, and the key block 65 is slidably fitted in the key block groove 67. Also, each partition plate 61a has an opening on the front surface of the front panel 62 with a width through which the key block 65 passes at a position corresponding to one of the characters for the PIN code written along the key block groove 67. A portion 61b is formed. Further, a dead bolt 64 is fixed to the upper or lower portion of the code code key member 61 so as to protrude in a direction substantially perpendicular to the key block groove 67.

  A slit 62a is formed in the front panel 62 at a position corresponding to the key block groove 67, and an alignment knob 65a connected to the inner key block 65 is attached to the outside of each slit 62a. Yes. In addition, a character for a password is written above or below each slit 62a.

  The code code lock 60 configured as described above is unlocked when the plurality of key blocks 65 are all aligned with the code by the positioning knob 65a, and the code code key member 61 is attached to the partition plate 61a. It moves by the interval. The deadbolt 64 is moved in the axial direction by operating the deadbolt operation knob 64a. In FIG. 18 (a), only one set of the key block 65 and the alignment knob 65a is shown in order to simplify the drawing.

  In the case of the code code lock 60, as shown in FIG. 18 (b), for example, a punch that prevents movement of the two sliding doors on a frame portion where two sliding doors (not shown) overlap. The member 66 is inserted, and the dead bolt 64 is inserted into the dead bolt receiving portion 66a formed in the bolt member 66. The dead bolt 64 prevents the movement of the pinning member 66, and the positioning knob 65a is operated so that the key block 65 is not unlocked unless it is aligned with the password.

  Although the code code locks 10, 20, 30, 30A, 50 shown in the first to fifth embodiments are all illustrated as horizontal examples in which the locking members 14, 34, 51 move in the horizontal direction, the embodiments are illustrated. Similarly to the case of the code code lock 60 according to No. 6, it can be used in a vertical type. In addition, the code code locks 10, 20, 30, 30A, 50 have been described as operating from both the outdoor side and the indoor side, but one side is embedded in a door, window frame, etc., and the other side is the room. It can also be used as a single-sided operation type code code lock so as to be located inside or outdoor.

  19 and 20 are diagrams showing a configuration example of a lock unit used in combination with the code code locks 10, 20, 30, 30A, 50, 60. FIG. FIG. 19 is a schematic cross-sectional view showing an example in which a code code lock (for example, code code lock 10) is embedded in a door such as a door, and is used in a vertical type, (a) is an unlocked state, (b) Indicates a locked state. FIG. 20 is a schematic cross-sectional view showing an example in which a code code lock (for example, code code lock 10) is applied to a crescent-type lock used in a sliding door, and (a) shows an unlocked state. , (B) shows the locked state.

  The lock unit shown in FIG. 19 includes, for example, the code code lock 10, the lock bar 71 and its storage unit 72, and a lock bar receiving unit 73. The code code lock 10 is embedded in the door 74 so that the operation surface faces the indoor side. A lock bar receiving portion 73 is disposed below the locking member 14 of the code code lock 10, and the lock bar receiving portion 73 is formed with a through hole 73 a large enough to fit the locking member 14. In addition, an accommodating portion 72 of the lock bar 71 is attached to a position corresponding to the lock bar receiving portion 73 of the outer frame 75 of the door 74, and the lock bar 71 is accommodated therein.

  Further, the lock bar 71 has a through hole 71 a formed at the tip side, and although not shown, a knob for operating the lock bar 71 projects to the indoor side and / or the outdoor side of the door 74. When the door 74 is closed, the lock bar 71 is inserted into the lock bar receiving portion 73 from an opening 73 b formed at a position corresponding to the lock bar 71 of the lock bar receiving portion 73. ing. Furthermore, when the code bar 10 is locked with the lock bar 71 inserted into the lock bar receiving portion 73, the locking member 14 is lowered to fit into the through hole 73 a of the lock bar 71. Yes.

  Since the lock part between the door 74 and the outer frame 75 is configured as described above, once locked, the door 74 cannot be opened unless the password lock 10 is unlocked. The lock bar 71 is provided with a flange portion 71a so that the lock bar 71 can stably maintain a closed state between the door 74 and the outer frame 75. It has become.

  The lock portion shown in FIG. 20 is an example in which a code code lock is applied to a crescent lock of a sliding door. For example, the code code lock 10, a semicircular hook 81, and a hook receiving portion 82 are used. And a push member 84 that is connected to the locking member 14 of the code code lock 10 by a cam mechanism 83. The code lock 10 to the hook 81 are fixed to the inner sliding door frame portion 85, and the hook receiving portion 82 is fixed to the outer sliding door frame portion 84. The code code lock 10 is attached so that the operation surface faces the indoor side. The hook 81 is supported so as to be rotatable around a fulcrum 81a.

In the case of locking, the locking member 14 of the code code lock 10 is lowered, the hook 81 is pushed by the push member 83 via the cam mechanism 83, the hook 81 is pushed into the hook receiving portion 82, and locked. Yes.
Since the lock portion of the two sliding doors is configured as described above, once locked, the hook 81 cannot be pulled out from the hook receiving portion 82 unless the code code lock 10 is unlocked. Therefore, the sliding door cannot be opened even if the vicinity of the crescent lock portion of the glass door is cracked, which is extremely effective for crime prevention.

FIG. 21 is a perspective view showing an overall configuration of a security door system 90 according to the seventh embodiment. The security door system 90 includes a door 91, a door outer frame 92, the code lock 50 according to the fifth embodiment incorporated in the door 91, a dead bolt 93a that locks between the door 91 and the door outer frame 92, and And a locking portion 93 including a receiving seat 93b (see FIG. 22).
FIG. 22 is an exploded perspective view showing members constituting the locking portion 93. (a) is a code code lock 50, (b) is a seat 93b of a dead bolt 93a, and (c) is a dead bolt guide 93c. Is shown. The dead bolt 93a is a part of the locking member 51 of the code code lock 50, and is formed on an extension thereof.

  Among these members, the deadbolt guide 93c is incorporated in the door 91 shown in FIG. 21, and the deadbolt 93a is housed in the deadbolt guide 93c and fixed to the door 91. The dead bolt 93a is provided with a dead bolt operating knob 93e. The dead bolt operating knob 93e is connected to the door 91 via a fixed shaft 93f that is passed through a slit 93d formed in the dead bolt guide 93c. It is set so as to protrude from the outdoor side and the indoor side. Therefore, the dead bolt 93a can be moved from the outdoor side and the indoor side to the unlocking side or the locking side.

  As already described, the code lock 50 (see FIGS. 12 and 17) includes an open / close lid 41 on the outdoor side, and the rotating plate 35A is covered with the open / close lid 41 except during operation. When the opening / closing lid 41 is opened and the switch is turned on in the unlocked state, the projection 53a of the locking member 51 is drawn into the main body 52 of the locking member 51, and all the rotary plates 35A are positioned at the password. The locking member 51, that is, the dead bolt 93a can be moved to the locking position without matching.

  When the door 91 is locked, the opening / closing lid 41 is opened, the dead bolt operating knob 93e is moved to the locking side, and the dead bolt 93a is inserted into the seat 93b. After locking, the position of each rotary plate 35A is shifted so that the password is not left as it is. However, even if the operation is not performed, in the case of the code code lock 50, since the reset mechanism of the rotating plate 35 is provided, the code code 50 is not left in a state aligned with the code code. By these operations, the door 91 is locked by the code code lock 50. Since each rotary plate 35A is reset from the position aligned with the password, there is almost no possibility of being unlocked.

  When unlocking the code code lock 50 and opening the door 91, the opening / closing lid 41 is opened, each rotary plate 35A is aligned with the code code, and in that state, the dead bolt operation knob 93e is moved to the unlock side. . As a result, the door 91 is unlocked and can be opened. After unlocking, the position of each rotary plate 35A is shifted so that the password is not left as it is. However, even if the operation is not performed, in the case of the code code lock 50, since the reset mechanism of the rotating plate 35 is provided, the code code 50 is not left in a state aligned with the code code.

  In the security door system 90 according to the seventh embodiment, the code code lock 50 is used. However, the security door system using the code code lock can be operated from both the inside and outside of the room. The code code locks 10, 20, 30, 30A, 40 other than the code lock 50 can be applied.

  In addition, in the security door system to which the code code locks 10, 20, 30, 30A, 40, and 50 are applied, it is preferable to use a tube lock, a thumb turn lock, or the like that is usually employed for the door. It is said that providing at least two locks for one door is preferable for crime prevention, and it is necessary to dare to lock it with a code lock when there is a person in the room or in a house, or when going out for a short time. This is because there is a case where it is thought that there is not, and it is possible to cope with such a case. Since tube locks, thumb turn locks and the like are relatively inexpensive, even if these locks are used in combination, the price of the security door system will not be so high.
