Description

  The present invention relates to a door locking device attached to an opening / closing body such as a sliding door or an opening door.

  Patent Document 1 states that “a horizontal dead bolt that moves back and forth in a horizontal direction in a lock box provided at a free end of a main door, and a vertical dead wheel that is orthogonal to the horizontal dead bolt and moves back and forth in the vertical direction. Matters incorporating deadbolts "are disclosed.

  The lateral deadbolt of Patent Document 1 is inserted into a receiving hole of a child door receiving member that protrudes from a vertical seat (front) of a lock box and faces the free end of the parent door, for example, The dead bolt protrudes from the horizontal surface seat (bottom wall) of the lock box and engages in a receiving hole of a receiving tool on the lower frame of the door frame. The example of this patent document 1 should be referred to as a “double dead lock for doors”. However, in the case where the door is locked simultaneously in the vertical direction and the horizontal direction with respect to the fixing member (door frame, support). Is compatible, but a plurality of (for example, two) horizontal dead bolts are not simultaneously engaged in the receiving holes of the fixing member in the vertical direction (for example, the receiving holes of the vertical frame and the receiving member provided on the vertical frame). Therefore, there is a problem that the installation location of the double dead lock is limited.

  When considering from the viewpoint of crime prevention on the child door side, the locking piece is only one dead bolt that enters from the vertical seat (front) to the receiving hole on the child door side. There is also a problem that it cannot be improved.

  Further, Patent Document 2 discloses "a door locking device in which a dead bolt and a single kama dead composed of a kama linked to the dead bolt are incorporated in a lock box". In addition, Patent Document 2 describes, for example, a cylinder lock or thumb turn that rotates by an operating force of a key, a drive member that operates in the locking / unlocking direction by the operation of the cylinder lock or thumb turn, and a driving force of the drive member. The tip part is composed of one camad that advances and retreats from the face seat of the lock box so as to engage the receiving hole of the fixing member in the vertical direction, and the one cameded includes a dead bolt, a support shaft, and a guide pin. The matter which consists of the hook which interlock | cooperates (follows) to a dead bolt via the guide means containing is disclosed.

  This patent document 2 should be referred to as a “camaded lock” with respect to the “double dead lock for doors” of patent document 1, and is generally a lock with a general “dead bolt only” or “comb only”. On the other hand, it is excellent in crime prevention.

  Therefore, at present, on the premise of the Kama dead lock described in Patent Document 2, there is a demand for the appearance of a door locking device that is more excellent in crime prevention.

FIG. 1 is a schematic explanatory diagram showing an environment for carrying out the invention. FIG. 1 is a schematic explanatory view at the time of locking in which the tip end portions (dead bolt and tip end portions of the hook) are engaged with the receiving holes 10 of the fixing member 7 when the door is closed, and FIG. 2 is a perspective view of the lock box 1. FIG. 3 is a schematic explanatory view showing the internal configuration of the lock box 1 at the time of unlocking.

  1 to 3, reference numeral 1 denotes a lock box. The lock box 1 is installed in a sliding door or an opening door as a specific example of the opening / closing body 2, for example. Of course, you may attach the lock box 1 to the inner wall surface of the opening-closing body 2 in the imposition state. The lock box 1 has a case body 1a, a case lid 1b, and a vertical face seat (front) 1c. The vertical face seat 1c has an upper opening 3 for an upper camaded 13 and a lower opening for a lower camaded 13 which will be described later. 4 are appropriately formed. In addition, unfixed fastener holes are formed at the upper and lower ends of the vertical seat 1c. Further, as shown in FIG. 2, one shaft hole 5 is formed in the central portion of the lock box 1 near the vertical seat 1 c. In addition, the lock box 1 is appropriately formed with an unnumbered circular fitting hole or the like.

  On the other hand, 7 is a vertical fixing member (a pillar, a vertical frame of a door frame, a receiving tool) facing the vertical surface seat 1c of the lock box 1. In this embodiment, the fixing member 7 is a receiving tool composed of a troyoke 8 and a strike 9 fixed to the vertical frame of the door frame, and the strike 9 is a pair of receiving parts up and down on the basis of the engaging portion 9a at the center. While having a hole (engagement hole) 10, the engaging portion 9 a at the center is connected to the trowel 8 via a strike deformation preventing member 11. The external structure of the lock box 1 is as shown in FIG. 2, and detailed items such as a plurality of fitting holes, protrusions, guides, and mounting fixtures formed in the lock box 1 are omitted.

  Note that the lock box 1 of the present embodiment is merely an example for explaining the implementation environment, so that a drive motor, gears, clutch means, and the like are provided in the lock box 1 to form a so-called “electric lock”. You can also Therefore, the dharma 12 as a driving member to be described later rotates not only by the operation force by the rotation operation of the key combination but also by the driving force of the drive motor.

(2) Main constituent members of the present invention The main constituent members incorporated in the lock box 1 of the present invention are a dharma 12, upper and lower kama dead (a person skilled in the art) 13, 13, and upper and lower kama dead, respectively. One axis (one axis) 6 shared by each base end portion of the coma constituting the synchronizer 15 and the synchronizing means 15 for advancing and retracting the two camads 13 and 13 simultaneously.

  The upper and lower kama deads 13 are locking pieces having the same function, and the upper or lower kama dead 13 is a dead bolt 16 that reciprocates in the horizontal direction, and is linked to the dead bolt 16 and has a common shaft 6 and a guide. It comprises a hook 19 that rotates a predetermined amount via means (for example, a long hole and a guide pin) 18.

  Thus, one of the features of the best mode (first embodiment) is that, as shown in FIG. 1 and FIG. At the same time, the base end portions 19b of the kama 19 constituting the upper and lower kama deads are supported by a single shaft 6 (see FIG. 5), and the upper and lower kama deads 13 and 13 are provided in the lock box 1 so as to be rotatable. At the same time, the front end 16a of the dead bolt 16 is engaged with the receiving hole 10 of the fixing member 7 and the hooked front end 19a of the hook 19 is received by the receiving means 10 at the time of locking shown in FIG. It hooks on the back surface of the hooking portion 9 a of the fixing member 7 around the hole 10.

  Another feature of the present invention is, for example, a receiver (an example of a vertical fixing member) shown in FIG. 7, and the receiver 7 is fixed to the vertical frame of the door frame as described above. A laterally concave troy poke 8 and a long plate-like strike 9 fixed to the upper and lower mounting ends of the troy poke 8 via a fixing tool (not shown). The strike 9 is an engaging portion 9a at the center. With the receiving holes 10 and 10 for the camaded 13 on the upper and lower sides, and the engaging portion 9a of the central portion is integrally connected to the vertical bottom wall 8a of the troyoke 8 via the strike deformation preventing member 11 Yes. In addition, a strike deformation preventing member 11 is provided integrally with the receiver in the receiver 7.

  By the way, although the structure of the strike deformation preventing member 11 is a matter of design change, in this embodiment, as shown in FIGS. 1 and 7 to 9, one end face abuts against the back surface of the engaging portion 9a in the central portion. In addition, a cylindrical support column 11a having a predetermined length whose other end surface is in contact with the inner wall surface of the vertical bottom wall 8a of the troyoke 8 and a plurality of stoppers screwed into female screws formed at both ends of the cylindrical support column 11a. It consists of a screw 11b.

  Furthermore, an example of the synchronizing means 15 of the present invention is a single rotating body having a size substantially the same as that of the dharma, and the rotating tooth of the rotating body is a driving tooth of the annular fitting portion of the dharma. A synchronizing arm 27 that is arranged in the vertical direction of the dharma so as to mesh with 25 and extends radially outwardly engages with an engaging portion 21 formed on the rear end portion of the dead bolt 16 of the other cammaded 13.

  In addition, the interlock or synchronization means 15 is disposed in the predetermined space 23 of the lock box 1 and drives the synchronization teeth 26 and the dharma 12 that mesh with the drive teeth 25 provided around the annular fitting portion 12a of the dharma 12. Formed at the rear end portion of the dead bolt 16 of the other cammaded (upper camaded in the drawing) 13 that is opposed in parallel to the dead bolt 16 of one cammaded (lower in the drawing) 13 with which the arm 22 is engaged. The rotating body has a synchronizing arm 27 that engages with the engaged portion 21. Therefore, the synchronization means 15 needs only one member.

(3) Specific Configuration of Main Components First, referring to FIG. 2, an upper camaded 13 and a lower camaded are formed from an upper opening 3 and a lower opening 4 of a vertical face seat (front) 1c of the lock box 1. The tip surface of 13 looks vertically symmetrical. As is clear from FIG. 2, the tip surface of the dead bolt 16 of the upper camaded 13 has a downward U-shape, whereas the tip surface of the dead bolt 16 of the lower camaded 13 has an upward U-shape. .

  Therefore, the dead bolt 16 of the kama dead 13 is formed so that at least the end face or longitudinal section of the tip edge is substantially U-shaped, and when the kama dead 13 is retracted (unlocked), the hooked tip 19 a of the kama 19 While being accommodated in the U-shaped tip portion 16a (FIG. 3), on the other hand, when the camedad 13 is advanced (locked), the hook-shaped tip portion 19a of the kama 19 can protrude from the substantially U-shaped tip portion 16a ( FIG. 1).

  Here, the upper and lower hooks 19 of the present embodiment will be described. As shown in FIG. 1 and FIG. 6 (b), the upper and lower hooks 19 jump out from the upper opening 3 and the lower opening 4 of the vertical face seat (front) 1c of the lock box 1 at the same time. Is facing the inside like a arm. Therefore, when the top end 16a of each dead bolt 16 is engaged with each receiving hole 10 of the fixing member 7 at the time of locking, each hook-like tip 19a of the upper and lower hooks 19 of the first embodiment It can be hooked in a state of being close to each other on the back surface of the hooking portion 9a corresponding to the central portion of the strike 9 in the periphery.

  Moreover, the upper and lower hooks 19 are integrally connected by a common shaft 6 as shown in FIG. 4 (explanatory diagram in a separated state) and FIG. 5 (explanatory diagram in a coupled state). In other words, the base end portions 19b of the upper and lower hooks 19 are bent so as to overlap each other, and are integrally connected via a single shaft 6 serving as a support shaft that passes through an unnumbered through hole. The single shaft 6 is horizontally mounted in the shaft hole 5 of the lock box 1 (see FIGS. 1 and 2).

  In addition, the upper and lower hooks 19 are linked (followed) to the dead bolt 16 via a guide means 18 including a common shaft 6 and a pair of upper and lower guide pins. Therefore, the common shaft 6 is a fixed support shaft that is laterally provided at the center near the vertical face seat 1c of the lock box 1 so as to pivotally support the base ends of the upper and lower wheels 19. The single fixed support shaft 6 is simultaneously rotated about the fulcrum. Therefore, the guide means 18 is configured so that, for example, each guide 19 can be rotated, for example, a guide slot or guide pin formed on the pad 19 side, and a dead bolt 16 side guided by the guide slot or guide pin. It is comprised from an unnumbered guide pin or a guide long hole.

  Next, the dead bolt 16 will be described. Referring to FIG. 3, a reverse-shaped engagement portion 21 is formed at the rear end portion 16 b of the lower dead bolt 16, while the rear end portion 16 b of the upper dead bolt 16 is formed with a cross-section shape. An engaging portion 21 having a shape is formed. In the present embodiment, the driving arm 22 of the dharma 12 as the driving means is selectively engaged with the inverted-shaped engaging portion 21 of the lower dead bolt 16. On the other hand, the synchronizing arm 27 of the rotating body 15 as the synchronizing means is selectively engaged with the C-shaped engaging portion 21 of the upper dead bolt 16.

  By the way, a pair of upper and lower urging means 31 having a click function is provided in the vertical direction at each rear end portion of the upper and lower dead bolts 16, and these urging means 31 correspond to the corresponding dharma 12 and the rotating body. Each of 15 is energized. Each urging means 31 includes a vertical moving rod located in the gap between the respective engaging portions 21 and a click spring wound around the vertical moving rod.

  Although other detailed matters will be briefly described, in the dharma 12, the annular fitting portion 12a is rotatably fitted to a fitting portion or a bearing provided in the lock box 1. Further, the circular fitting portion (this embodiment) or the shaft portion of the rotating body 15 as the synchronizing means is also fitted to the fitting portion or the bearing provided in the lock box 1 so as to be rotatable. Further, as shown in FIGS. 6A and 6B, the upper opening 3 and the lower opening 4 formed in the vertical face seat 1c of the lock box 1 can each enter and exit each of the comers 19. It has a stepped opening.

(4) Operation When the door is closed, if an operation key, for example, a key inserted in a cylinder (not shown) is operated, the dharma 12 rotates in the direction of arrow A (clockwise) shown in FIG. When the dharma 12 rotates in the direction of the arrow A, the driving arm 22 of the dharma 12 pushes out the lower dead bolt 16 of the camad dead. At that time, the driving teeth 25 of the dharma 12 mesh with the synchronizing teeth 26 of the synchronizing means 15 Therefore, the synchronizing means 15 simultaneously rotates in the direction of arrow B (counterclockwise) shown in FIG. 3 through the dharma 12 and pushes the upper dead dead bolt 16 by the synchronizing arm 27. .

  Thus, when the upper and lower dead bolts 16 are horizontally moved simultaneously based on the driving force of the dharma 12, the tip 16a of the lock box 1 is engaged with the upper and lower receiving holes 10 of the vertical fixing member 7 at the same time. Advance from the face seat 1c. As shown in FIG. 1, when locking, when the distal end portion 16 a of the dead bolt 16 is engaged with the receiving hole 10 of the fixing member 7, the upper and lower hooks 19 interlocked with the dead bolt 16 via the single shaft 6 or the like. Each hook-shaped tip 19a is hooked in the approaching state on the back surface of the hook portion 9a at the center of the fixing member (the strike 9 in this embodiment).

  In this locked state, when a force is applied to the sliding door 1 or the door 1 in the opening direction, a force is intensively applied to the engaging portion 9a (when the opening / closing body is a sliding door) or the fixing member 7 having the receiving hole 10. However, in this embodiment, the engaging portion 9a and the strike (the portion corresponding to the strike) at the central portion are the strike deformation preventing member 11. Is not easily deformed.

  In the first example described in the embodiment of the invention, the opening / closing body 2 is either a sliding door or an open door that rotates in the horizontal direction. Although not particularly illustrated, the structure of the strike deformation preventing member 11 is not a columnar shape, but is formed in a support frame shape having a plurality of engaging portions (engaging claw pieces, engaging protrusions, etc.) as will be described later. Also good.

  Hereinafter, in the column of this embodiment, the second embodiment, the third embodiment, and the like of the present invention will be described. In the description of these embodiments, the same parts as those in the first embodiment are denoted by the same or similar reference numerals, and redundant descriptions are omitted.

  10 to 12 show a second embodiment. The second embodiment is different from the first embodiment in the synchronization means 15A. That is, the synchronization means 15A is disposed in the lock box 1 so as to mesh with the racks 35 provided at the opposite end portions inside the dead bolts 16A of the upper and lower camads 13A, respectively. This is a pair of upper and lower camedded synchronizing small gears 36.

  By the way, the small gears 36 are respectively supported by a total of four unnumbered perfect circular shaft holes formed in the lock box 1 via unnumbered support shafts at both ends thereof. In other words, the pair of upper and lower small gears 36 are disposed at a substantially central portion of the lock box 1, and the small gear 36 located below is disposed at the opposite end of the lower dead bolt 16 </ b> A in the length direction of the dead bolt. Is engaged with the lower movable rack 35 formed in a predetermined amount, while the small gear 36 located on the upper side is formed in a predetermined amount in the length direction of the dead bolt at the opposite end of the upper dead bolt 16A. Is engaged with the movable rack 35.

  Therefore, in the second embodiment, when the dharma 12 rotates during locking, the upper and lower camads 13A move synchronously via the upper and lower racks 35 and the camaded synchronizing small gear 36, and the tip of each dead bolt 16A. The portion engages with the receiving hole 10 of the fixing member 7 and the tip 19a of the hook 19 can be hooked on the back surface of the engaging portion 9a of the fixing member around the receiving hole 10 (see FIG. 10).

  Next, FIGS. 13 to 16 show a third embodiment of the present invention. The third embodiment differs from the first embodiment in a link mechanism in which the synchronization means 15B is mainly composed of two links. In other words, the synchronizing means 15B of the second embodiment is configured such that the central portion is pivotally supported by the pair of upper and lower fixed shafts 38, and the inner ends connected to each other move in the front-rear direction while drawing an arcuate locus. These are two links for cammaded synchronization that are connected by a movable pin 39 and are connected by a pair of upper and lower second connection movable pins 40 whose outer ends move simultaneously in the vertical direction.

  That is, in the synchronizing means 15B, for example, as shown in FIG. 13, two links 37, 37 for camaded synchronization are arranged between the base end portion 19b of the upper and lower cams 19 and the dharma 12.

  The central portions of these links 37 are respectively supported by a pair of upper and lower fixed shafts 38 that are horizontally mounted on the lock box 1, and the inner end portions 37a and 37a that are connected to each other draw an arc-shaped locus. However, the outer end portions 37b and 37b are connected via a pair of upper and lower second connection movable pins 40 and 40 that move simultaneously in the vertical direction. The upper and lower dead bolts 16B and 16B are connected to each other.

Note that the pair of upper and lower links 37 and the upper and lower dead bolts 16B have a “reverse” shape when locked (FIG. 13), while a “ku” character when unlocked (FIG. 14). Further, in the middle (FIG. 15), a long hole for the first connecting movable pin 39 guide and a long hole for the second connecting movable pin 40 guide are respectively provided so as to form a “vertical line”. It is formed appropriately.
In the above configuration, when the dharma 12 rotates during locking, the upper and lower camads 13B move synchronously via the two links 37, and the tip of the dead bolt 16B engages with the receiving hole 10 of the fixing member 7. At the same time, the tip of the hook 19 can be hooked on the back surface of the hooking portion 9 a of the fixing member 7 around the receiving hole 10. Thus, even if the gear mechanism including the movable rack is replaced with the link mechanism (synchronizing means) 15B mainly composed of the two links 37, the same object as the first embodiment can be obtained.

  Next, FIGS. 17 to 21 show a fourth embodiment of the present invention. The fourth embodiment differs from the first embodiment in the synchronization means 15C. The synchronizing means 15C is pivotally attached to a second drive arm 27A extending on the opposite side of the first drive arm of the dharma 12C and is used as a guide for the control fitting 41. The second link 37A is guided and is connected to the rear end of the dead bolt 16C of the other camad dead 13C.

  In the fourth embodiment, as in the third embodiment, the synchronization means composed of a rack and a pinion is replaced with a link mechanism (synchronization means) 15C mainly composed of two links 27A and 37A. Therefore, in describing the link mechanism (synchronizing means) 15C of the fourth embodiment, the same parts as those of the link mechanism (synchronizing means) 15B of the third embodiment are denoted by the same reference numerals for convenience of explanation. .

  In the fourth embodiment, a second drive arm 27A corresponding to one link (first link) extending on the opposite side of the first drive arm 22 is provided in the annular fitting portion 12a of the dharma 12C.

  Therefore, the fourth embodiment differs from the first embodiment in that the second drive arm 27A of the dharma 12C as the first link and the other dead bolt of the other camaded (upper camaded in the embodiment) 13C. A second link 37A that is connected to the rear end portion of 16C (upper dead bolt) via a second connecting movable pin 40A and is pivotally supported by a fixed shaft 38A that is horizontally mounted on the lock box 1 is This is that the portion is connected via a control fitting 41 that is rotatably connected to the protruding end portion of the second drive arm 27A via the first connecting movable pin 39A.

  In addition, the second driving arm (first link) 27A and the dead bolt for synchronizing with the dharma 12C at the rear end of the second driving arm 27A of the dharma 12C and the dead bolt 16C of the other camad dead 13C. The second link 37A on the side is arranged in a connected state via a control fitting 41 having a guide function, and the inner end portion 27a of the second drive arm 27A moves in the front-rear direction while drawing an arcuate locus. One end of the connecting fitting 41 is pivotally connected to the connecting fitting 41 via one connecting movable pin 39A, while the inner end 37a is fitted in a longitudinal guide groove 42 formed in the connecting fitting 41. The long plate-like second link 37A has a central portion (including a portion closer to the central portion) supported by a fixed shaft 38A on the lock box side, and an outer end portion 37b provided continuously with the central portion. The other deadbol 16C has a U-shaped or bifurcated link engaging portion engages the second coupling movable pin 40A provided at the rear end of.

  By the way, in the present embodiment, the opposite end (on the drawing, the lower side) of the rear end of the other dead bolt 16C (upper dead bolt) is appropriately cut out 43. This is because the sheath-shaped control fitting 41 having openings at both ends is slidably fitted to the inner end portion 37a of the long plate-like second link 37A through the longitudinal guide groove 42, and the second drive arm 27A. When the first connecting movable pin 39A on the side moves in the front-rear direction while drawing an arcuate locus, it rotates with the fixed shaft 38A of the lock box 1 that supports the second link 37A as a fulcrum. This is to prevent the shaft 38A from obstructing the forward / backward movement of the other dead bolt 16C.

  Therefore, when the notch 43 is not formed at the rear end portion of the dead bolt 16C as in the present embodiment, for example, the fixed shaft 38A horizontally mounted on the lock box 1 is formed at the rear end portion so as not to be an obstacle. Horizontal holes and required openings should be formed.
