Description

  The present invention relates to a slide operation device used for a movable louver window or the like.

  In the movable louver window, the slat can be opened and closed by an indoor operation, but it is preferable from the viewpoint of crime prevention that the slat does not open when a force is applied to the outdoor slat. Patent Document 1 describes a conventional movable louver window opening / closing operation device that enables such an operation.

The opening / closing operation device described in Patent Document 1 locks a movable member connected to a slat, an operation member that moves the movable member in the vertical direction, and a spring biased so as to protrude and engage the movable member side. The lock member has a slope that converts the displacement of the operation member in the vertical direction into the displacement of the lock member, and a notch into which the lock member enters when the lock member protrudes. In this device, since the lock member is inserted into the notch, the slat does not open or close even when an external force is applied to the slat outdoors. However, when the operation member is operated indoors, the lock member is notched by the slope. In order to enter and exit, the angle can be adjusted by rotating the slats.
Japanese Patent Laid-Open No. 2002-47868

  In the opening / closing operation device described in Patent Document 1, the operation force of the operation member directly acts on the movable member that opens and closes the slat. In such a structure, in the case of a heavy slat made of a glass plate or the like, a large operating force is required, and there is a problem that operability is poor.

  Further, since the opening / closing angle of the slat is stepwise, there is an inconvenience that a fine angle adjustment cannot be performed. Further, when the opening / closing angle of the slat is changed, the lock member repeatedly engages with the notch, so that there is a noise such as a click or a click and there is a problem that a quiet operation cannot be performed.

  The present invention has been made in consideration of such conventional problems, and even a heavy slat made of glass or the like can be operated with a small operating force, and the slat can be angled steplessly. It is an object of the present invention to provide a slide adjusting device that can be adjusted and that can be quietly operated without generating noise.

  The slide operation device according to the first aspect of the present invention includes a shaft member connected to the operated member and capable of moving up and down, a guide member inclined with respect to the length direction of the shaft member, and a larger diameter than the shaft member. A lock member having a lock hole through which the shaft member penetrates, an elastic member for inclining the lock member so as to bite into the shaft member, and a fulcrum for tilting the lock member A slider that slides along the guide member in a state in which the shaft member and the guide member penetrate, a release portion that contacts the lock member and releases the biting of the lock member into the shaft member; A sliding piece that has a contact portion that contacts the slider, the shaft member penetrates and moves along the shaft member, and the sliding movement of the slider is caused by the lock member biting into the shaft member. When the sliding piece moves, the sliding piece releases the bite of the lock member into the shaft member, and the slider slides along the guide member to move the shaft member up and down. Features.

  In the first aspect of the invention, since the lock member is inclined with respect to the shaft member, the lock member bites into the shaft member, so that the sliding movement of the slider is locked, and the operated member is locked at the angle. When the slide piece moves, the biting of the lock member into the shaft member is released, and the slider slides along the guide member, so that the shaft member moves up and down and the angle of the operated member can be adjusted. At this time, since the guide member is inclined, the weight of the operated member is decomposed by the inclination angle of the guide member, and the slider can be slid by a force that overcomes the component force. Therefore, it becomes possible to operate with a small operating force.

  According to the first aspect of the present invention, even if an external force is directly applied to the operated member with respect to the locked state, the lock member is in a locked state in which the shaft member is bitten. The angle cannot be adjusted. Further, since the angle adjustment of the operated member is performed only by the sliding movement of the slider, the operation is quiet without noise.

  The invention according to claim 2 is the slide operation device according to claim 1, wherein the guide member is disposed along the length direction of the shaft member in a state of being inclined along the length direction of the shaft member. And a plurality of balls disposed between the guide rail and the slider.

  The invention described in claim 3 is the slide operating device according to claim 2, wherein the guide rail is inclined at at least two different angles.

  The invention according to claim 4 is the slide operation device according to claim 1, wherein when the sliding piece moves along the shaft member, the release portion releases the biting of the lock member into the shaft member. Thereafter, the abutting portion abuts on the slider to slide the slider.

  A fifth aspect of the present invention is the slide operating device according to the first aspect, wherein the operated member is a slat of a movable louver window.

  In the present invention, since the slider slide movement for adjusting the angle of the operated member is performed along the inclined guide member, the operation can be performed with a small operating force. Even if an external force is directly applied to the operated member, the angle cannot be adjusted by an operation from the operated member because the lock member is in a locked state where the shaft member is engaged. Furthermore, since the angle adjustment of the operated member is performed only by the sliding movement of the slider, a quiet operation without noise can be achieved.

  As shown in FIGS. 1 and 2, the movable louver window has a plurality of slats 1. Each slat 1 is rotatably attached to a slat shaft 3, and the slat shaft 3 is fixed to a frame 2 of the louver window. A link 4 is attached to each slat 1, and the link 4 is rotatably attached to a connecting rod 6 by a pin 5. The connecting rod 6 extends in the vertical direction, and all the links 4 of the slat 1 are attached to the connecting rod 6.

  In the above structure, when the connecting rod 6 moves up and down, the slat 1 rotates around the slat shaft 3 in synchronization with the movement of the connecting rod 6. In FIG. 2, when the connecting rod 6 moves upward, the slat 1 rotates counterclockwise and closes, and when the connecting rod 6 moves downward, the slat 1 rotates clockwise and opens. Become. In this embodiment, the slat 1 functions as an operated member.

  As shown in FIGS. 1 to 5, the slide operation device 7 of this embodiment includes a guide rail 9 that is a constituent member of a guide member, a shaft 10 as a shaft member, a sliding piece 11, a slider 12, A lock plate 13 as a lock member, a compression spring 14 as an elastic member, and an operation lever 15 are provided. The slide operating device 7 is located on the indoor side, while the slat 1 is located on the outdoor side.

  The shaft 10 extends in the left-right direction, and both ends thereof are connected to the connecting rod 6 of the louver window. That is, as shown in FIG. 2, both ends of the shaft 10 are connected by being inserted into elongated holes 6 a provided in the connecting rod 6 and fixed by the bolts 16. The shaft 10 can move up and down with respect to the frame 2, and the connecting rod 6 moves up and down as the shaft 10 moves up and down.

  The guide rail 9 is disposed along the length direction of the shaft 10 as shown in FIG. The guide rail 9 is arranged to be inclined with respect to the length direction of the shaft 10, and both ends thereof are fixed to the frame 2 by nuts 8. In this embodiment, the guide rail 9 is inclined so as to be lowered to the right.

  The guide rail 9 and the shaft 10 pass through the slider 12 (see FIG. 5). An elongated hole 12 a for allowing the guide rail 9 to pass therethrough is formed in the upper portion of the slider 12. As shown in FIG. 6, the guide rail 9 has a rectangular cross section, and the elongated hole 12 a is formed in the same rectangular cross section as the guide rail 9. Such a slider 12 is slidable along the guide rail 9. When the slider 12 slides, the shaft 10 penetrating the slider 12 moves up and down.

  In this embodiment, a guide member is constituted by the guide rail 9 and the ball 18. The ball 18 is disposed between the guide rail 9 and the slider 12, and as shown in FIG. 6, ball hemispherical grooves 9a are formed at four locations on both outer surfaces of the guide rail 9, A similar hemispherical recess 12 b is formed on the inner surface of the slider 12. A plurality of these hemispherical grooves 9a and 12b are provided along the length direction of the guide rail 9 and the slider 12, and the ball 18 is inserted into each of them.

  As shown in FIG. 5, the lower portion of the slider 12 is bifurcated into a pair of legs 21 and 22. The pair of leg portions 21 and 22 are opposed to each other, and inclined surfaces 21a and 22a inclined in a direction away from each other downward are formed on the opposed surfaces. The apexes of the slopes 21a and 22a serve as action portions 21b and 22b as fulcrums for tilting the lock plate 13 described later. Shaft holes 21c and 22c through which the shaft 10 penetrates are formed in the lower portions of the leg portions 21 and 22.

  A pair of the lock plate 13 is provided so as to correspond to the leg portions 21 and 22 of the slider 12. As shown in FIG. 8, each lock plate 13 has a lock hole 13a having a diameter slightly larger than the diameter of the shaft 10, and the shaft 10 passes through the lock hole 13a. A compression spring 14 into which the shaft 10 is inserted is disposed between the pair of lock plates 13. The pair of lock plates 13 are arranged on the opposing surfaces of the legs 21 and 22 of the slider 12 with the compression spring 14 interposed therebetween. Each of the lock plates 13 is inclined in the same direction as the inclined surfaces 21a and 22a with the action portions 21b and 22b of the slider 12 as fulcrums by the spring force of the compression spring 14, and the edges 13b and 13c of the lock holes 13a are caused to be in the shaft 10 Bite into. As the edges 13b and 13c of the lock hole 13a bite into the shaft 10, the sliding movement of the slider 12 is locked.

  As shown in FIG. 5, the sliding piece 11 has a box shape with a bottom surface and a side surface rising from the bottom surface, and the outside of the bottom surface is connected to the operation lever 15. A shaft 10 passes through the sliding piece 11, and the sliding piece 11 is movable along the length direction of the shaft 10. Opposing surfaces on the bottom surface are release portions 11a and 11b that abut against the lock plate 13 and release the biting of the lock plate 13 into the shaft 10. The side surfaces rising from the bottom surface are positioned outside the leg portions 21 and 22 of the slider 12 and are contact portions 11c and 11d that contact the leg portions 21 and 22, respectively.

  The operation lever 15 is connected to the sliding piece 11 by snap-fitting to the bottom surface of the sliding piece 11 (see FIG. 5). Accordingly, by moving the operation lever 15 in the left-right direction, a moving force in that direction acts on the sliding piece 11.

  Next, the operation of this embodiment will be described. FIG. 5 shows a locked state in which the lock plate 13 bites into the shaft 10 due to the spring force of the compression spring 14. In this state, the clearance L 1 between the release portions 11 a and 11 b of the sliding piece 11 and the lock plate 13 is The sliding piece 11 is set to be smaller than the gap L2 between the contact portions 11c and 11d of the sliding piece 11 and the slider 12.

  In the state of FIG. 5, when the slat 1 is opened and closed by an indoor operation, the operation lever 15 is moved rightward. By the movement in the right direction, first, the release portion 11a on the left side of the sliding piece 11 comes into contact with the corresponding lock plate 13. 7 and 8 show a state in which the operating lever 15 is further moved to the right, and the left lock plate 13 pushed by the left releasing portion 11a of the sliding piece 11 moves the right acting portion 21b of the slider 12. It rotates counterclockwise as a fulcrum. As a result, the edges 13b and 13c of the lock hole 13a of the lock plate 13 are released from biting into the shaft 10, and the slider 12 is unlocked. In this case, since L1 <L2 is set, the above-described release is performed before the left contact portion 11c of the sliding piece 11 contacts the leg portion 21 of the slider 12.

  When the operating lever 15 is moved further to the right, the gap between the contact portion 11c on the left side of the sliding piece 11 and the slider 12 disappears, and the contact portion 11c starts to push the slider 12. At this time, since the lock plate 13 on the left side is held in the unlocked state by the release portion 11a, the action portion 21b, and the compression spring 14, the left lock plate 13 moves the operation lever 15, that is, the right direction of the slider 12. Move to the left following the slide movement to. The right lock plate 13 loses the fulcrum inclined in the lock direction because the right action portion 22b of the slider 12 is separated, and enters the unlocked state.

  As described above, since both the pair of lock plates 13 are in the unlocked state, the operation lever 15 and the slider 12 can smoothly move in the right direction. When the slider 12 slides to the right, the slider 12 is guided by the guide rail 9, so that the entire slide operation device 7 moves to the lower right along the guide rail 9. By this movement, the shaft 10 moves downward, and the connecting rod 6 connected to the shaft 10 also moves downward as shown in FIGS. When the connecting rod 6 moves downward, the slat 1 rotates clockwise around the slat shaft 3 to perform the opening operation of the slat 1.

  When closing the slat 1, the operation lever 15 is moved leftward. By this movement, the right lock plate 13 is unlocked by the same operation as described above, and then the left lock plate 13 loses the fulcrum and is unlocked. Therefore, the operation lever 15 can be smoothly moved to the left side. The slider 12 moves integrally with the operation lever 15 in the left direction. The movement of the slider 12 moves the guide rail 9 in the upper left direction along the guide rail 9. When the slider 12 moves in the upper left direction, the connecting rod 6 moves in the upper direction, so that the slat 1 rotates counterclockwise about the slat shaft 3 and the slat 1 is closed. In this case, when the operation lever 15 is moved in the left direction, an upward force is applied to the shaft 10 by the weight of the slat 1, and therefore the operation lever 15 can be moved with a small force.

  When the operation lever 15 is released following the above opening / closing operation of the slat 1, the lock plate 13 bites into the shaft 10 by the spring force of the compression spring 14 and the movement of the slider 12 is locked. For this reason, the vertical movement of the shaft 10 stops and the rotation of the slat 1 stops. Thereby, the slat 1 is hold | maintained at the angle.

  The operation of the lock member in the above operation will be described with reference to FIGS. As shown in FIG. 2, the own weight F <b> 1 of the slat 1 acts as an upward force on the connecting rod 6. Since the guide rail 9 is inclined, the self-weight F1 is decomposed into a force F2 perpendicular to the inclined surface S and a force F3 along the inclined surface S as shown in FIG. In this embodiment, a plurality of balls 18 are arranged between the guide rail 9 and the slider 12, and the balls 18 roll between the guide rail 9 and the slider 12 when the slider 12 slides. For this reason, the frictional resistance between the slope S and the ball 18 is extremely smaller than the frictional resistance during direct sliding. As a result, the resistance due to the force F2 becomes small enough to be ignored, so that F1> F3. Since the slider 12 can slide along the guide rail 9 by applying a force that overcomes the small force F3, the slat 1 can be rotated only by the small force F3. Adjustment can be performed with a small operating force. Therefore, even with a heavy glass slat, the angle adjustment operation can be performed with a small force. Here, when it is necessary to further reduce the force F3 for sliding the slider 12, the inclination of the guide rail 9 can be further reduced.

  In the present invention, the ball 18 can be omitted. The operating force of the slider 12 when the ball 18 is omitted is the resistance force by F3 + F2 (F2 × friction resistance). In this case as well, since the resistance force is F1> F3 + F2, the slider has a sufficiently small force. 12 can be operated.

    FIG. 2 shows a state in which the slat 1 is completely closed. In contrast, when the slat 1 is to be opened by applying a force directly to the slat 1 outdoors, that is, the slat 1 is rotated around the slat axis 3 in the clockwise direction. When trying to rotate, a downward force acts on the connecting rod 6. This force acts as a downward force on the shaft 10 via the bolt 16. When the shaft 10 moves downward, the slider 12 moves in the lower right direction along the guide rail 9, so that the left action portion 21b of the slider 12 rotates the left lock plate 13 in the clockwise direction to lock the slider. The plate 13 is inclined with respect to the shaft 10, and the edges 13 b and 13 c of the lock hole 13 a bite into the shaft 10. Thereby, the lock by the lock plate 13 is performed. When the force to the slat 1 is further increased and the force for moving the slider 12 in the right direction is further increased, the force that the lock plate 13 bites into the shaft 10 is increased and the locking force is increased. Therefore, the slat 1 cannot be opened outdoors.

  When the open slat 1 is to be closed outdoors, an upward force is applied to the shaft 10, and the slider 12 attempts to move in the upper left direction along the guide rail 9. In the same manner as described above, the shaft 10 is bitten and locked. As described above, the slat 1 cannot be opened and closed from outside.

  In the above operation, the angle adjustment of the slat 1 is performed only by the sliding movement of the slider 12. For this reason, the angle adjustment of the slat 1 can be performed steplessly and a quiet operation without noise can be performed.

  FIG. 12 shows a second embodiment of the present invention. In this embodiment, the guide rail 9 has a shape inclined at two different angles. That is, the guide rail 9 is formed by the first rail portion 9c and the second rail portion 9d provided continuously from the terminal end of the first rail portion 9c. The first rail portion 9c is inclined at a certain large angle with respect to the length direction of the shaft 10, and the second rail portion 9d is inclined at a smaller angle than the first rail portion 9c. The first rail portion 9c corresponds to a small load at the time of opening the slat 1, and the second rail portion 9d corresponds to a large load when the slat 1 is opened to some extent. Thus, the guide rail 9 inclined at two angles has an advantage that it can be operated with a constant operating force even if the open state of the slat 1 changes.

  The present invention is not limited to the above embodiments, and various modifications can be made. For example, the elastic member that biases the lock plate 13 may be formed by overlapping a plurality of disc springs. Further, the present invention can be applied to devices other than the movable louver window.
