JP6557578B2 - Sliding locking device - Google Patents

Description

  In the present invention, for example, like a French drop, an operation member such as a rod rod is slid to move the locking member to the locking position or the unlocking position, so that the shoji, door, partition, etc. can be fixed or opened. The present invention relates to a sliding lock device.

  In general, the French drop used in the market is roughly divided into a receiving hole provided on the door frame by moving the slider up and down by rotating the operation lever pivotally attached to the main body 180 degrees in the vertical direction. Rotating French drop that appears and disappears (for example, see Patent Document 1), and a slider that is provided with a knob, and a slider that moves the slider directly up and down with the knob so that the rod connected to the slider appears and disappears in the receiving hole. A French drop (see, for example, Patent Document 2) is known.

  In the case of a French drop of the type in which the operating lever is rotated, the operating lever is reversed after being rotated and stored in the receiving groove along the front plate of the main body. Therefore, even if the rod rod is forced to move from the outside to the unlocking position at the locking position, the lever does not rotate, so that it can be reliably locked at the locking position. However, if the tip of the rod bar is not fully in the receiving hole or if dust is collected in the receiving hole, the operation lever protrudes from the front plate of the main body via the rod bar and stops. Therefore, if the door is closed in this state, the door may not be closed, or if the door is forcibly closed, the lever may be deformed or damaged.

  Also, in the case of sliding French drop, the knob does not protrude from the front plate of the main body, so accidents like rotary French drop do not occur, but the slider is not locked, so it is appropriate from the gap between the door and door frame There is a possibility that the rod rod can be moved to the unlocking position by inserting the tool, and there is a problem in crime prevention. Therefore, as described in Patent Document 2, a plurality of engagement holes are provided at intervals in the length direction of the slide bar, a leaf spring having an engagement protrusion is provided at the tip, and the rod bar is moved to a position where the rod bar is moved. The slide bar is held by engaging the engagement protrusion with the engagement hole by a spring action, but with such a holding mechanism, the load resistance of the rod rod is much smaller than that of the rotary French drop, so it is easy. May be unlocked. If the spring pressure is increased, it will not be possible to operate easily during locking and unlocking, and even if the spring pressure is not increased, the spring pressure is applied in addition to the weight of the rod rod during operation. It must be slid against these forces, and the operation becomes heavy.

  As locking and unlocking devices for doors, shojis, etc., various devices using a slide mechanism are used in addition to dropping in France. For example, a fastening device that moves and locks the lock pin, a device that locks and unlocks by moving an interlocking plate provided with an engagement pin, a lifting and lowering window locking device that moves and moves the latch member horizontally, and various other types Are known (for example, Patent Documents 3 to 5). These devices are also basically mechanisms for locking and unlocking by moving a slider and moving a locking member such as a lock pin or a latch member directly or via another member. As with dropping, there is a problem that the slider cannot be locked lightly and reliably.

JP-A-8-144610 (FIG. 2) JP 2006-118283 A (FIGS. 1 and 3) JP 2002-188336 A (FIGS. 1 and 2) Japanese Patent Laying-Open No. 2006-22523 (FIGS. 1 and 7) JP 2012-1896 A (FIGS. 6 and 7)

  As described above, the present invention is to provide a sliding locking device that can be locked and unlocked in a locking position and can be lightly operated in a sliding locking device that locks and unlocks by moving the slider.

  According to the present invention, a slider that communicates with a locking member and an operation member that is provided with an action portion that is operated by a knob and has a tip pressing surface and a side pressing surface are slid in parallel in a main body having an engaging recess. A stopper provided with a pressing edge and an engaging edge in an opposing state is pivotally attached to the slider, and when the operating member is moved, the tip pressing surface of the operating member is brought into contact with the pressing edge of the stopper. When the slider is moved by bringing the engaging edge into sliding contact with the inner surface of the main body and moving the slider to a position corresponding to the engaging recess, the engaging edge of the stopper engages with the engaging recess. The sliding lock is characterized in that the stopper is rotated, the operation member is moved to a position where the side pressing surface is in contact with the pressing edge, the rotation of the stopper is prevented, and the movement of the slider is locked. Location is provided, the problems are solved.

  According to the present invention, the operating member and the slider are provided with a hook portion that engages when the operating member is returned, and the French pin that connects the rod rod to the slider as the locking member or the lock pin as the locking member There are provided a fastening bracket provided on the slider, a raising / lowering window locking device in which the slider also serves as a latch member, and other various sliding locking devices.

  The present invention is configured as described above, and when the operating member is moved, the slider is moved by the tip pressing surface of the operating member hitting the pressing edge of the stopper, and the engaging edge of the stopper corresponds to the engaging recess of the main body. When the stopper rotates, the engaging edge engages with the engaging recess, and the operation member moves to bring the side pressing surface into contact with the pressing edge of the stopper. The slider can be locked in a state where it is locked by the member and the stopper is prevented from rotating. Therefore, even if the slider is to be returned from the outside, the stopper does not rotate while engaged with the engaging recess, so that the slider cannot be moved, and the slider can be reliably held in the locked state. At this time, since the spring is not used for the rotation of the stopper, it is easy to move the slider, it can be operated easily, and it is rigid as a whole and is not easily destroyed.

  As described above, the present invention can be applied to various kinds of locking devices using a French dropping, drawing device, closing metal fitting, raising / lowering window locking device, and other sliding mechanisms. For example, in the case of a double door having a moving side door 1 and a fixed side door 2 as shown in FIG. 1, two French droppings 4 are provided on the small side of the fixed side door 2 at the top and bottom as shown in FIG. 2. As is publicly known, when the tip of the rod bar 5 provided so as to be movable in the vertical direction is moved in a direction to be inserted into the receiving hole 6 provided on the door frame or the floor surface, it is locked and retracted from the receiving hole. If you move in the direction you want to unlock, it will be unlocked. If the door is a partition, a French drop can be provided on the inner surface of the door (not shown).

  Referring to FIGS. 3 to 5, the main body 7 of the French drop (sliding lock device) 4 of the present invention has a mounting hole 8, and slides the knob with fingers with a depth that extends in the longitudinal direction and does not protrude from the surface. A storage plate 12 having a substantially U-shaped cross section is formed by having a front plate 10 provided with a knob hole 9 having a width and a length that can be operated, and by providing a side plate 11 in an opposing state behind the front plate 10. Part of the rear ends of the side plates 11 are connected by a connecting plate 13 to prevent the members provided in the storage portion from falling off. One side plate 11 has an engagement recess 14 formed therein. In the embodiment shown in the figure, the engaging recess 14 is cut away from a part of the side plate 11 and opened outward. However, a part of the inner surface of the side plate may be recessed to form an engaging recess. . In the storage portion 12, a slider 15 and an operation member 16 are stored side by side so as to be slidable in the vertical direction in FIG. As shown in FIG. 5, the slider 15 and the operation member 16 are in sliding contact with the back surface of the front plate 10, and are slidably in contact with the inner surface (sliding surface) 17 of the side plate. It has the sliding surfaces 20 and 21 which the members 16 slidably contact.

  The slider 15 has a head portion 23 formed at the tip of a screw portion 22 for screwing the rod rod 5 as shown in FIG. The intermediate portion 24 is about half the width of the storage portion. When the slider 15 is moved, a step portion 26 is formed in the intermediate portion of the main body 7 on the side adjacent to the engagement recess 14 so as to attach the stopper 25, and a collar portion 27 is formed on the side surface on the operation member 16 side. Is provided.

  The stopper 25 has a pressing edge 28 and an engaging edge 29 facing each other so as to intersect at about 90 degrees, and is pivotally attached to the slider 15 by a pin 30 so as to be able to rotate within the step portion 26. When the leading edge of the pressing edge 28 protrudes from the side surface of the slider in the direction of the operating member, the leading edge of the engaging edge 29 is located along the side surface of the slider. When the tip of the projection protrudes from the side surface of the slider to the side plate 11, the tip of the pressing edge 28 is formed along the side surface of the slider. In other words, the pressing edge 28 of the stopper 25 protrudes toward the operation member 16 when the tip of the engagement edge 29 is in sliding contact with the inner surface (sliding surface) 17 of the side plate 11 of the main body. The length is such that when the tip of the engagement edge 29 enters the engagement recess 14 provided in the side plate 11, it rotates and is positioned along the side surface of the stepped portion 26. The length of the engagement edge 29 is such that when the tip of the pressing edge 28 protrudes toward the operation member 16, the tip is in sliding contact with the inner surface of the side plate 11 and corresponds to the engagement recess 14. It is a length that can enter the recess 14 and reliably engage with the edge 31 of the engagement recess 14. Note that the edge 31 of the engagement recess 14 extends in a direction substantially perpendicular to the moving direction of the slider, that is, the horizontal direction in FIG. As shown in FIG. 5, the stopper 25 has a substantially right isosceles triangle shape with a rounded apex, and is pivotally attached to the slider 15 inside the apex of the triangle, and one side of the opposite side becomes a pressing edge 28. The other side is an engagement edge 29. Moreover, although the front edge of the pressing edge 28 and the engagement edge 29 are formed in a substantially right-angled fan shape connected by an arcuate surface, it may be formed in a triangle surrounded by a straight line by connecting the front ends in a straight line. In addition, a small curved surface can be formed at the tip of the engagement edge.

  The operation member 16 has a knob 32 protruding from the knob hole 9 on the front surface, an operation main body 33 having a shape that is slidably inscribed in the storage portion 12, and the slider from the tip of the operation main body 33. 15 has a tip 34 extending along the line 15. The tip portion 34 is formed with an action portion 37 having a tip pressing surface 35 positioned in the moving direction of the slider 15 and a side pressing surface 36 positioned on the slider side. 38. A protruding edge 39 is provided on the side of the tip pressing surface 35. The leading end 34 is provided to be biased toward the side plate via a stepped portion so as to receive the intermediate portion 24 of the slider 15.

  The operation member 16 is provided with a guide pin 41 that enters the guide groove 40 provided on the side plate 11 of the main body, and the operation member can be moved to a position where the guide pin 41 hits the end of the guide groove 40. Further, on the front plate 10 side, there is a hole 44 for storing the click ball 43 biased by the spring 42, and the click ball 43 is formed on the back surface of the front plate 10 at the end of the movement when the operation member 16 is moved. It enters the received receiving hole 45 and gives a click feeling to the movement of the operation member. In addition, you may make it provide these guide grooves, a guide pin, a click ball | bowl, and a receiving hole in the member of the reverse side in the Example shown to a figure.

  In the unlocked state with the above configuration, as shown in FIGS. 6 and 7, the operation member 16 is in the lowered position, and the stopper 25 is in a position where the pressing edge 28 faces the distal end pressing surface 35 of the operation member 16. is there. At this time, the engaging edge 29 of the stopper 25 is in contact with the inner surface 17 of the side plate, and the rotation of the stopper 25 is prevented in FIG. From this state, when the operating member 16 is lifted by holding the knob 32, the slider 15 is lifted via the stopper 25 by being pushed by the tip pressing surface 35 of the operating member as shown in FIG.

  When the engaging edge 29 of the stopper 25 comes close to the engaging recess 14 provided in the side plate 11 in the middle of ascending, the tip of the engaging edge 29 gradually enters the engaging recess 14 as shown in FIG. The rotation prevention of 25 is gradually released, and the stopper starts to rotate clockwise. The rotation of the stopper continues until the tip of the engagement edge 29 completely enters the engagement recess 14 and comes into contact with the edge 31. Even after the rotation of the stopper 25 stops and the slider 15 stops rising, the operating member 16 continues to rise. When the side pressing surface 36 of the operation member moves to a position where it sufficiently contacts along the pressing edge 28 of the stopper 25, the guide pin 41 comes into contact with the end of the guide groove 40 and the movement of the operation member stops ( (See FIGS. 10 to 12). At this time, the rod bar 5 connected to the slider 15 has its tip inserted into the receiving hole of the door frame, and the door is locked. Even if the rod 25 is pushed down in the locked state, the stopper 25 is prevented from rotating clockwise or counterclockwise with the engagement edge 29 engaged with the engagement recess 14. 15 cannot be pushed down, and can be reliably locked in the locked state.

  When the knob 32 is pushed downward from the state shown in FIG. 10, the side pressing surface 36 of the operating member 16 gradually moves away from the pressing edge 28 of the stopper 25 in the middle of the lowering, and the stopper 25 can rotate counterclockwise. When the flange portion 38 of the operation member 16 and the flange portion 27 of the slider 15 come into contact with each other, the stopper 25 is rotated counterclockwise and the engagement edge 29 is released from the engagement recess 14 of the side plate, and the slider 15 is 16, the operation member 16 is lowered to a position where the guide pin 41 corresponds to the end of the guide groove 40, and returns to the unlocked state as shown in FIG.

  In the above embodiment, the slider is configured to be locked at the raised position. However, the slider can be configured to be locked at the lower position, and the slider can be locked at either the raised position or the lowered position. Can be configured. FIGS. 13 to 15 show such an embodiment, and the same components as those in the above embodiment will be described with the same reference numerals. When the side plate 11 of the main body 7 is placed in two positions, the rising position and the lowering position. Engaging recesses 14a and 14b are provided. Further, step portions 26a and 26b are formed in the upper and lower portions of the slider 15, and upper stoppers 25a and lower stoppers 25b having the same configuration as described above are pivotally attached to the respective step portions in opposite directions. The operation member 16 is provided with action portions 37 having a tip pressing surface 35 and a side pressing surface 36 corresponding to the upper stopper 25a and the lower stopper 25b, respectively. These operating portions are provided in such a relationship that the lower side pressing surface 36b is separated from the pressing edge 28 of the lower stopper 25b before the upper tip pressing surface 35a hits the pressing edge 28 of the upper stopper 25a. A protrusion 46 is formed on the side surface of the slider 15, and flanges 38 a and 38 b are formed on the operation member 16 so as to face the protrusion in the vertical direction in FIG. 13.

  With the above configuration, when the operating member 16 is raised, as shown in FIG. 14, the slider 15 moves via the upper stopper 25a in substantially the same manner as in the above-described embodiment, and the upper stopper 25a is moved to the engaging recess 14a. The upper stopper 25a rotates in the clockwise direction and engages with the engaging recess, and the operating member further moves up to lock the slider 15 in the raised position (see FIG. 15). During the above movement, before the tip pressing surface 35a of the operating member 16 hits the upper stopper 25a, the lower side pressing surface 36b moves away from the pressing edge 28, and the lower stopper 25b becomes rotatable in the clockwise direction. Therefore, the upward movement of the slider 15 is not hindered.

  On the other hand, when the operating member is lowered from the raised position, the upper side pressing surface 36a is separated from the pressing edge 28 of the upper stopper 25a in the middle of the lowering, and the upper stopper 25a is allowed to rotate counterclockwise and the lower tip pressing surface. The slider 15 starts to descend when 35b hits the pressing edge 28 of the lower stopper 25b. When the engagement edge 29 of the lower stopper 25b corresponds to the lower engagement recess 14b, the lower stopper 25b rotates counterclockwise so that the engagement edge 29 enters the lower engagement recess 14b, and the operating member descends downward. The slider 15 can be locked in position.

  As described above, the sliding lock device of the present invention can be applied to various lock devices. For example, in the case of a fastener as shown in Patent Document 3, a member having a lock pin 47 is connected to the slider 15 as a locking member (see FIG. 16), and when the slider 15 is moved, the receptacle 48 is moved. It is only necessary that the lock pin is engaged to be locked in the locked state.

  In the case of a mechanism for moving the interlocking plate up and down as shown in Patent Document 4, a transmission plate 50 for operating the interlocking plate 49 is connected to the slider 15 (see FIG. 17), and a receiving groove provided in the transmission plate 50 is provided. 51 is inserted into the interlocking pin 52 of the interlocking plate 49, and when the slider 15 moves, the interlocking plate 49 is moved so that the engaging pin 53 engages with a receiving device (not shown) and can be locked by locking. do it.

  In the case of a raising / lowering window or a shoji locking device as shown in Patent Document 5, as shown in FIG. 18, the main body 7 is attached to the window or shoji 54 so that the slider 15 moves in the horizontal direction. It may be used as a latch member, and when the slider 15 is moved in the horizontal direction, the tip end portion engages with the window frame or the shoji frame 55 and can be locked by locking.
