Description

  TECHNICAL FIELD The present invention relates to a lock device with a built-in lock that locks a hook of a lock body housed in an internal summit bag with a receiving device in an external summit bag, and a sash window provided with the lock device. It is.

  The lock body of the lock body housed in the sash window of the pull-type, single-drawing, or double-drawing (draw) type sash window is operated by the operating member, and appears from the outdoor side of the internal sushi bowl. As an internal lock type locking device that engages and locks the receiving device in the outer summoning bowl, an operation member that slides up and down along the indoor side surface of the inner summoning bowl, and an operating member The main body has a first gear train with a small reduction ratio and a second gear train with a large reduction ratio that convert linear motion into rotational motion and transmit the torque to the device (key piece). In the stage where it appears and disappears from within the mating rod, the operating force of the operating member is transmitted to the hanging tool via the first gear train having a small reduction ratio, and in the stage where the hanging tool engages or disengages from the receiving tool (key holder). The operating force of the operating member is applied to the hanging tool through the second gear train having a large reduction ratio. It is made be configured to obtain (see Patent Document 1.).

JP 2006-118135 A (FIG. 6-9)

In the lock device with a built-in bag of Patent Document 1, the hook is moved downward by the operation of moving the indoor operation member downward to engage the receiver, and the engagement is performed by the operation of moving the operation member upward. Because it is configured to be released, the locking and unlocking operation can be performed with natural motion without a sense of incongruity, and the first gear train with a small reduction ratio is used when the hanging device protrudes from the inside summoning cage. The power can be transmitted and the hanging tool can be quickly projected. When the hanging tool is pushed into the engagement piece (engagement portion), the power is transmitted by the second gear train having a large reduction gear ratio and a small operating force. It has the feature that it can be operated.
However, since the transmission of the operating force for operating the operating member is switched between the first gear train and the second gear train, which have greatly different reduction ratios, and transmitted to the hanging tool, such gear train switching is performed. (Gear transfer) Since the operation may not be successful, there is room for improvement from the viewpoint of the reliability and smoothness of the operation.

Further, a small gear is meshed with the rack, and the first gear train is engaged with the small gear provided coaxially with the small gear, and the small gear is meshed with the large gear. The transmission of power by the second gear train to be switched is switched, and due to restrictions on the arrangement of these gear trains, the rotation angle of the hanging tool cannot be increased, and the rotation angle is about 100 °, for example. Therefore, the angle of rotation of the hanging tool is increased, and the engaging piece of the receiving device is sufficiently drawn to the indoor side by the hanging tool, and the outdoor shoji is sufficiently drawn to the indoor shoji, thereby being airtight and watertight. There is also room for improvement from the viewpoint of improving crime prevention.
In addition, it is necessary to shift the fan-shaped cogwheel and fan-shaped cogwheel concentrically with respect to the hanging tool in the axial direction, and since the large-diameter gear is arranged on the lateral side of the rack, the width of the lock body Since the thickness of a direction becomes comparatively large and it cannot be used for the shoji with the small width of the summon bowl, the application object is limited.
Furthermore, since the operating member can be moved downward even when the shoji is opened, the operating member is moved downward with the shoji opened so that the hanging tool protrudes from the inside summoning cage. If the shoji is closed in this state when an incorrect operation is performed, the hanger or the like may be damaged, and if the shoji is not completely closed, moving the operating member downward will cause the hanger and the receiver to move. It may be damaged by collision.

  Therefore, in view of the above-mentioned situation, the present invention intends to solve the problem that the operation of locking / unlocking can be performed by a natural motion that moves the operation member on the indoor side downward or upward, so that the locking / unlocking can be performed reliably and smoothly. The angle of rotation of the hook can be increased so that the engaging piece of the receiver can be sufficiently pulled to the indoor side, and the application object can be expanded by slimming the lock body Provided are a lock device with a built-in lock and a sash window provided with the lock device, which can prevent the breakage of a hanging tool or the like due to an erroneous operation by allowing the operation member to move downward only when the shoji is closed. In the point.

  In order to solve the above-mentioned problem, the lock device with a built-in bag according to the present invention is used for a pull-type sash window that opens and closes an opening by sliding a plurality of shojis arranged in a frame in the width direction. The arcuate engagement plate of the lock body of the lock body housed in the shoji shoji sash is operated from the indoor side by an operating member that slides in the vertical direction, and is projected and retracted from the outdoor side of the inner squirrel. A lock-incorporating locking device that locks by engaging with an engaging piece of a receiving member in an outer summoning bag of an outer shoji, wherein the lock body is attached to the arc-shaped engaging plate of the hook. A gear portion formed on the opposite side across the moving support shaft, a small diameter gear supported by the rotation support shaft so as to mesh with the gear portion, and a large size that rotates concentrically with the small diameter gear. A diameter gear and a tooth that always meshes with the large diameter gear are formed on the outdoor side surface, and the tooth is It is obtained by a rack extending vertically which is connected to the operating member while being Ido movably supported.

  Here, in the lock body, a trigger extending in the indoor / outdoor direction is formed with a slope inclined in the indoor direction as it approaches the direction toward the external summit bowl at the tip portion protruding from the outdoor side surface of the internal summit bowl. And an elastic biasing means for biasing the trigger in the outdoor direction, and a guide gear supported by a rotating support shaft so as to mesh with the rack, and the slope of the tip portion is closed by closing the shoji When the trigger is pushed by an external summon and the trigger moves in the indoor direction against the urging force of the elastic urging means, the guide gear can be rotated, and the sash is closed from the closed state. When the trigger is urged by the urging force and moved in the outdoor direction, the guide gear is locked by the trigger, and the guide gear is rotated in the direction of lowering the rack. Preferably is control.

  A sash window according to the present invention includes the lock device with a built-in heel for the purpose of solving the problems.

  According to the sash built-in locking device and the sash window equipped with the locking device according to the present invention, the lock body housed in the summoning jar of the indoor shoji, with respect to the arcuate engagement plate of the hanging tool, A gear portion formed on the opposite side across the rotation support shaft, a small-diameter gear supported by the rotation support shaft to mesh with the gear portion, and the concentric rotation with the small-diameter gear A large-diameter gear, and teeth that are always meshed with the large-diameter gear are formed on the outdoor side surface, and are supported so as to be slidable in the vertical direction, and a rack extending in the vertical direction connected to the operation member. By the operation of moving the operation member on the indoor side downward, the hanging tool is rotated, the arcuate engagement plate is moved downward and engaged with the engagement piece of the receiver, and the operation member is moved upward. The hook is rotated in the opposite direction to the rotation and the engagement is released. Because, it is possible to perform the operation of the locking and unlocking by the natural motion with no discomfort.

In addition, a large-diameter gear meshes with the rack that moves up and down integrally with the indoor operation member, and a gear portion formed on the hanging gear meshes with the small-diameter gear that rotates integrally with the large-diameter gear, Since these are always meshed, there is no gear train switching (gear transfer), so that locking and unlocking can be performed reliably and smoothly.
Furthermore, it is not a configuration in which the transmission of the operating force for operating the operating member is switched between the first gear train and the second gear train having greatly different reduction ratios, and there is no restriction on the arrangement of these gear trains. Since the rotation angle of the hanging tool is relatively large and the rotation angle can be set to about 140 °, for example, the receiving object is sufficiently drawn to the indoor side by the hanging tool, and the outdoor obstacle is sufficiently moved to the indoor obstacle. Therefore, airtightness, watertightness and crime prevention can be improved.
In addition, the rack that moves up and down integrally with the operation member on the indoor side meshes with the large-diameter gear located on the outside of the room, and the small-diameter gear that rotates integrally with the large-diameter gear is formed as a hook. Since the gear portion is engaged, it is not necessary to shift the concentric fan-shaped large gear and fan-shaped small gear to the hanging tool in the axial direction, and a large-diameter gear is arranged on the lateral side of the rack. Therefore, since the thickness of the lock body in the width direction can be made relatively small and slim, the application target can be expanded.

Further, a trigger extending in the indoor / outdoor direction in which an inclined surface that is inclined toward the indoor direction is formed on the front end portion of the lock body that protrudes from the outdoor side surface of the internal summit bowl toward the outer summon bowl, Elastic urging means for urging the trigger in the outdoor direction; and a guide gear supported by a rotation support shaft so as to mesh with the rack; and the slope of the tip is closed by closing the shoji In a state where the trigger is pushed by the summoning rod and the trigger moves in the indoor direction against the urging force of the elastic urging means, the guide gear can be rotated, and the shoji can be moved from the closed state. In a state where the trigger is urged by the urging force and moved in the outdoor direction, the guide gear is locked by the trigger, and the rotation of the guide gear in the direction of lowering the rack is regulated. In addition to the above effects, in the state where the shoji is opened, the rotation of the guide gear in the direction of lowering the rack is restricted by the trigger, so the operating member is moved downward to summon the hanging tool. It cannot be protruded from the bag to the outside of the room.
Therefore, only when the shoji is closed, the operating member can be moved downward to engage the arc-shaped engaging plate of the hanging tool with the engaging piece of the receiving tool, and the shoji can be locked securely. In this case, it is not possible to perform an erroneous operation or the like for projecting the hanging tool from the inner summon bowl to the outside of the room, so that breakage of the hanging tool or the like can be prevented.

Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments shown in the accompanying drawings, and includes all the embodiments that satisfy the requirements described in the claims. It is a waste. In this specification, the front side in the direction from the indoor side (see ID in the figure) to the outdoor side (see OD in the figure) is the front, the rear is the rear, and the left and right are the front. A view seen from the room side is a front view.
Here, examples of the pull-type sash window in which the lock device with a built-in scissors according to the present invention is used include a pull-type sash, etc. Will describe a sliding sash as an example of a pull-type sash window.

FIG. 1 is a perspective view showing a state in which a heel built-in locking device 10 according to an embodiment of the present invention is attached to the sash 1, and FIGS. 2 to 6 are configuration explanatory views of the heel built-in locking device 10. FIG. 2 (a) is an enlarged perspective view of the main part showing the state of the inside candy basket 5 and the outside candy basket 6 as viewed from the indoor side ID, and FIG. FIG. 3 is a perspective view showing an external appearance of the lock device 10 with a built-in hook, and FIGS. 4 and 5 are views from the left showing the configuration of the gear transmission mechanism and the like of the lock body 11. FIGS. 6 and 6 are also perspective views. FIGS. 4 and 6 show the state in which the shoji 3 and 4 are opened, and FIG. 5 shows that the shoji 3 and 4 are closed and the hanging tool 21 is engaged with the receiving tool 22. Indicates the state.
7A is a perspective view of the guide spur gear 15 and the trigger 16, FIG. 7B is a perspective view of the large diameter spur gear and the small diameter spur gear, and FIG. 8 is an enlarged view for explaining the operation of the trigger 16. Yes, FIG. 8 (a) shows the trigger operating state, FIG. 8 (b) shows the trigger release state, and FIG. 8 (c) shows the state in which the trigger portion is intentionally pushed with the shoji opened.

As shown in FIG. 1, the sliding sash 1 has an opening by sliding a slidingly movable indoor-side shoji 3 and an outdoor shoji 4 arranged in a frame 2 in the left-right direction (width direction, finding direction). The main parts of the lock device 10 with a built-in lock are accommodated in the inner summoning cage 5 of the indoor shoji 3 and the outer summoning cage 6 of the outdoor shoji 4. Locking and unlocking can be performed by operating.
That is, as shown in FIGS. 1 and 2, the lock (stopper) 9 is pushed to enable the operation member 7 to be operated, the shojis 3 and 4 are closed to be in a trigger release state, which will be described later, and the indoor side surface 5A of the inner summon bowl 5 By sliding the operation member 7 that slides in the vertical direction along the sway, the arcuate engagement plate 21A of the hanging tool 21 is moved to the outdoor side of the inner summit bar 5 via a gear transmission mechanism of the lock body 11 described later in detail. It emerges from the side surface 5B, engages with the engaging piece 22A of the receiving member 22 in the outer summoning cage 6 and is locked or unlocked by releasing the engagement.
Here, as shown in FIGS. 2A and 3, the receiving member 22 is supported by a support member 24 (for example, formed integrally with the support member 24), and the support member 24 is an outside summoning bowl. 6 to the indoor side surface 6A.

Next, the structure in the lock body 11 of the lock device 10 with a built-in bag accommodated in the internal summon basket 5 will be described.
As shown in FIGS. 3 to 6, the case 12 </ b> A of the lock body 11 and the rear side (indoor ID) in the lid 12 </ b> B extend in the vertical direction, and teeth are formed on the front side (outdoor OD) surface. The rack 13 is located by a guide spur gear 15 pivotally supported by a left and right rotation support shaft S3 and a left and right rotation support shaft S1. Since the large-diameter spur gear 14A supported by the shaft meshes with the rear side (indoor ID) surface, the indoor upright piece 12E of the case 12A abuts, so that the rack 13 is slidably supported in the vertical direction. Is done.

Below the guide spur gear 15, a trigger 16 extending in the front-rear direction (indoor / outdoor direction, depth direction, prospective direction) is placed in the case 12 </ b> A within the guide recessed portion 16 </ b> A (see also FIG. 7A). Since the protruding guide protrusion 12C enters and slides, it is supported so as to be movable in the front-rear direction, and the rear surface of the spring receiving portion 16B protruding upward is cut and raised from the case 12A to be integrated. The compression coil spring 17, which is an elastic biasing means whose rear end is supported by the formed cut and raised pieces, is biased forward, and the shoji 3, 4 (see FIG. 1) shown in FIG. 4 is opened. Thus, the front surface of the spring receiving portion 16B is abutted against the rear surface 12F of the front plate of the case 12A.
Further, an arcuate recess 16C is formed on the upper surface of the rear portion of the trigger 16, and a horizontal locking surface 16D is formed on the upper surface of the rear end portion thereof. The right boss portion (see FIG. 7 (a) also includes a locked surface 15A formed in a shape obtained by cutting the peripheral surface. That is, the outer shape of the cross section of the boss portion is substantially D-shaped.

  Therefore, in the state in which the shoji 3, 4 (see FIG. 1) shown in FIGS. 4 and 8A is opened, the trigger 16 is urged forward by the compression coil spring 17, and the front end portion thereof is internally called. Projecting from the outdoor side surface 5B of the mating rod 5 to the outdoor side OD, the front surface of the spring receiving portion 16B is stationary with the rear surface 12F of the front plate of the case 12A being stopped, and the guide spur gear 15 is locked. The locking surface 16D of the trigger 16 is brought into contact with the surface 15A and the guide spur gear 15 is locked. The guide spur gear 15 is viewed from the left side (toward FIGS. 4 and 8A). Since the clockwise rotation is restricted, the rack 13 cannot be moved downward (hereinafter referred to as “trigger operating state”).

  On the other hand, when the shoji 3 and 4 are closed (see arrow A in FIG. 1), the trigger 16 is formed at the front end portion (the front end portion protruding from the outdoor side surface 5B of the inner summoning bowl 5). As the outer summoning basket 6 comes into contact with the slope 16E (see FIG. 6) that inclines backward (in the room direction) as it approaches the right side (the direction toward the outer summoning bowl 6), the trigger 16 moves backward. However, the locking surface 16D of the trigger 16 does not come into contact with the locked surface 15A of the guide spur gear 15 so that the right boss of the guide spur gear 15 can be obtained. Since the arc-shaped concave portion 16C of the trigger 16 is positioned below the boss portion so as to face the boss portion, the rotation of the guide spur gear 15 is not restricted (hereinafter referred to as “trigger release state”). ).

As shown in FIG. 3 to FIG. 6, since the connecting plate 20 to which the operation member 7 is connected is fixed to the rack 13, the operation member 7 is slid up and down in the trigger release state, so that the rack 13 13 slides up and down together with the operation member 7.
According to the configuration in which the rack 13 and the operation member 7 are connected by the connecting plate 20, by changing the shape (size) of the connecting plate 20, the inner sump 5 having various cross-sectional shapes can be obtained. The lock body 11 can be accommodated in the summoning bowl.
Further, a small-diameter spur gear 14B is also supported on the right side of the large-diameter spur gear 14A by the left-right rotation support shaft S1, coaxially with the large-diameter spur gear 14A, and the large-diameter spur gear 14A and the small-diameter spur gear 14B. As shown in FIG. 7B, the engaging convex shaft 14C of the large-diameter spur gear 14A is fitted into the engaging hole 14D of the small-diameter spur gear 14B, so that they rotate together.

The small-diameter gear 14B meshes with an arcuate engagement plate 21A of a hanging tool 21 that is pivotally supported by a left and right rotation support shaft S2 and a gear portion 21B that is integrally formed on the opposite side across the rotation support shaft S2. To do.
Therefore, when the operation member 7 is slid downward in the trigger release state (see arrow B in FIG. 4), the rack 13 moves downward via the connecting member 20, and the small diameter spur gear together with the large diameter spur gear 14A. Since 14B rotates, the hanging tool 21 rotates to the position (refer FIG. 5) engaged with the receiving tool 22 with the gear part 21B meshing with the small diameter spur gear 14B.

Further, when the operation member 7 is slid upward in the trigger release state (see arrow C in FIG. 5), the rack 13 moves upward via the connecting member 20 and has a large diameter in the direction opposite to the above operation. Since the spur gear 14, the small diameter spur gear 14 </ b> B, and the gear portion 21 </ b> B are rotated, the hanging tool 21 is rotated to a position where the engagement with the receiving tool 22 is released (see FIGS. 4 and 6).
Since the ends 32A and 32B of the tension coil spring 32 are hooked on the spring hook 21C protruding from the side surface of the hanging tool 21 and the spring hook 12D protruding from the inner surface of the lid 12B, the tension coil spring 32 is attached. Since the force acts in the locking direction from the middle of locking when the hook 21 is engaged with the receiving tool 22 and acts in the unlocking direction from the middle of unlocking to release the engagement, the locking and unlocking can be performed with a light operation. Can be performed reliably.

Further, on the front surface of the stepped portion on the right side of the teeth of the rack 13, engagement recesses 13A and 13B are formed at the upper and lower sides thereof, one end 18A is stopped by a pin 19A, and the pin 19B is inserted into the coil. The other end 18B formed in the arc shape of the kick spring 18 is in contact with the front surface of the step portion of the rack 13 in an elastically deformed state.
Then, the end 18B of the kick spring 18 engages with the lower engagement recess 13B of the rack 13 at the upper end (see FIGS. 4 and 6) of the stroke that moves in the vertical direction of the rack 13, and the lower end of the stroke (FIG. 5). ), The end 18B of the kick spring 18 is engaged with the upper engagement recess 13A of the rack 13, so that a click feeling is obtained at the upper and lower ends of the stroke, and the operability is improved and the rack 13 is dropped by its own weight. Is prevented.

In the gear transmission mechanism as described above, the rack 13 and the large-diameter spur gear 14A that meshes with the rack 13 are made of synthetic resin, and the small-diameter spur gear 14B and the gear portion 21B that meshes with the small-diameter spur gear 14B are formed. By making the tool 21 made of steel, the gear train close to the load side and applied with a larger torque is made of metal to suppress wear, and the gear train far from the load side (close to the operation member 7 on the input side) is synthesized. The operation sound is reduced as it is made of resin.
As described above, the concentric large-diameter spur gear 14A and the small-diameter spur gear 14B that rotate integrally around the rotation support shaft S1 are made of different materials. A structure with a concave-convex fitting that fits into the engagement hole 14D (see FIG. 7B) facilitates the large-diameter spur gear 14A and the small-diameter spur gear 14B of different materials while reducing the number of parts and the number of processing steps. And it can integrate reliably.

When the shoji 3 and 4 (refer to FIG. 1) are opened (trigger operation state) and the trigger 16 is pushed from the outdoor OD by mischief or the like, the operation member 7 (the connecting plate 20 and the rack 13) is If it has fallen, as shown in FIG.8 (c), the position of the trigger 16 in the front-back direction (indoor / outdoor direction) is the trigger operation state shown in FIG. 8 (a) and the trigger shown in FIG. 8 (b). It is an intermediate position from the released state.
In this state, since the rotation of the guide spur gear 15 engaged with the rack 13 is not restricted by the trigger 16, the operation member 7 (the coupling plate 20, the rack is indicated by an arrow D in FIG. 8C). 13) By pushing up, the guide spur gear 15 rotates as shown by an arrow E in the figure, and easily returns to the trigger operating state shown in FIG.

  According to the locking device 10 with a built-in bag and the sliding sash 1 (sash window) provided with the locking device 10, the indoor ID operation member that closes the shoji 3 and 4 and releases the trigger is performed. An operation of moving the operating member 7 upward by rotating the hook 21 by rotating the lever 7 and moving the arcuate engagement plate 21A downward to engage with the engaging piece 22A of the receiving member 22. Thus, the hook 21 is rotated in the opposite direction to the rotation and the engagement is released, so that the unlocking / unlocking operation can be performed with a natural motion without a sense of incongruity.

In addition, a large-diameter gear 14A meshes with the rack 13 that moves up and down integrally with the operating member 7 of the indoor side ID, and a small-diameter gear 14B that rotates integrally with the large-diameter gear 14A is formed on the hanging tool 21. Since the gear portion 21B meshes and these are always meshed, there is no gear train switching (gear transfer), so that locking and unlocking can be performed reliably and smoothly.
Furthermore, the transmission of the operating force for operating the operating member 7 is not configured to be switched between the first gear train and the second gear train having greatly different reduction ratios, and there is no restriction on the arrangement of these gear trains. Therefore, the rotation angle of the hanging tool 21 can be made relatively large and the rotation angle can be set to about 140 °, for example. It can be drawn to the indoor side shoji 3 sufficiently, so that airtightness, watertightness and crime prevention can be improved.

  In addition, a large-diameter gear 14A positioned on the outdoor side OD meshes with the rack 13 that moves up and down integrally with the operation member 7 of the indoor ID, and a small-diameter gear 14B that rotates integrally with the large-diameter gear 14A. Since the gear portion 21B formed on the hanging tool 21 meshes with the hanging tool 21, it is not necessary to shift the concentric fan-shaped large gear and fan-shaped small gear in the axial direction with respect to the hanging tool 21, and the rack 13 Since the large-diameter gear is not disposed on the side in the width direction, the thickness of the lock body 11 in the width direction can be made relatively small and slim, and thus the application target can be expanded.

Furthermore, when the shoji 3 and 4 are opened (the trigger operating state), the trigger 16 restricts the rotation of the guide spur gear 15 in the direction in which the rack 13 is lowered, so that the operation member 7 is moved downward. It is not possible to move the hanger 21 from the inner summon basket 5 to the outdoor side.
Therefore, only when the shoji 3 and 4 are closed (the trigger release state), the operating member 7 is moved downward to engage the arcuate engagement plate 21A of the hanging tool 21 with the engaging piece 22A of the receiving tool 22, It can be locked securely, and in the state in which the shoji 3 and 4 are opened (the trigger operation state), it is impossible to perform an erroneous operation or the like for projecting the hanging tool 21 from the inner summon 5 to the outdoor OD. Breakage of the tool 21 and the like can be prevented.
