Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of an opening / closing body employing an opening / closing body device having a locking device according to the present invention.
The opening / closing body device having the locking device can be suitably used for an opening / closing body that is a constituent member of the shutter device 51, for example, the slat type shutter curtain 17. In the shutter device 51, a storage case 59 is attached to an upper part of a building opening 57 provided with a residential window sash 55. Guide rails 13 and 13 provided on the left and right sides of the opening 57 guide the side portion 11 of the shutter curtain 17. Accordingly, the shutter curtain 17 is guided up and down, and is fed out and stored in the storage case 59.

FIG. 2 is a perspective view of the indoor side that is the back surface of the opening and closing body shown in FIG.
The shutter curtain 17 is a seat plate 15 having a long lower end. The shutter curtain 17 and the seat plate 15 are made of an aluminum extrusion molding material. In the present embodiment, a locking device 23 is attached to the seat plate 15. The locking device 23 is rotatably provided with a lever 19 along the seat plate 15, and unlocks the shutter curtain 17 by a mechanism which will be described later when the operation tip 21 is rotated upward. A string-like operation member 25 as a flexible long member is supported on the operation tip 21 of the lever 19. A belt-like member 27 as a member to be bonded is attached to the guide rail 13 along the longitudinal direction of the guide rail 13. In the present embodiment, the guide rail 13 is manufactured using an aluminum material. The string-like operation member 25 and the belt-like member 27 are configured to be magnetically attached to each other and detachable as will be described later.

FIG. 3 is a front view of the vicinity of the locking device shown in FIG.
The shutter curtain 17 is configured to lock the retractable lock bars 61 and 61 protruding from the side portion 11 to the projections 63 and 63 provided in the guide rails 13 and 13 to guide the shutter curtain 17 in the opening direction. To regulate.

FIG. 4A is a front view of the locking device in a locked state, and FIG. 4B is a front view of the unlocked state.
In the locking device 23, a pair of parallel slide bars 65, 67 spaced vertically are accommodated slidably along the longitudinal direction of the seat plate 15. The slide bars 65 and 67 are connected to the lock bars 61 and 61 via shafts 69 and 69, respectively. The slide bars 65 and 67 are slid in the direction in which the shafts 69 and 69 approach, thereby retreating the lock bars 61 and 61 and releasing the lock with the protrusions 63 and 63.

  A rotation member 71 is rotatably provided at one end side of the locking device 23. The rotation center 71 of the rotation member 71 is located in the center part in the separation direction between the slide bars 65 and 67. The rotation member 71 is provided with engagement pins 75 and 75 for sliding the slide bars 65 and 67 with the rotation center 72 interposed therebetween. The lever 19 is extended to the rotating member 71. As shown in FIG. 4B, the rotating member 71 slides the pair of slide bars 65 and 67 in the direction in which the lock bars 61 and 61 are moved backward as the lever 19 is rotated upward. Coil springs 73 and 73 that urge the slide bars 65 and 67 in a direction in which the lock bars 61 and 61 protrude are stretched around the slide bars 65 and 67, respectively.

  Therefore, when the shutter curtain 17 is lowered for closing, the protruding lock bars 61 and 61 come into contact with the protrusions 63 and 63 and retract against the urging force of the coil springs 73 and 73. When the lock bars 61, 61 pass through the protrusions 63, 63, the lock bars 61, 61 protrude again by the urging force of the coil springs 73, 73, and are locked below the protrusions 63, 63 as shown in FIG. The locked state is set to restrict the rising of the curtain 17.

  On the other hand, as shown in FIG. 4B, when the lever 19 is rotated upward via the string-like operating member 25 in the locked state, the slide bars 65 and 67 moved via the engagement pins 75 and 75 are used. , The lock bars 61, 61 are retracted inward to release the locking with the projections 63, 63, and the unlocked state is obtained.

  The shutter curtain 17 is fully opened, and almost the entire seat plate 15 is stored in the storage case 59. In this state, the string-like operation member 25 fixed to the lever 19 is in a state of hanging downward from the storage case 59. Therefore, even when the shutter curtain 17 is pulled out from the stored state, the closing operation of the shutter curtain 17 can be easily started by pulling the string-like operation member 25.

The lever 19 has a distal end formed with an operation distal end 21 that protrudes in the opposite direction to the unlocking operation direction and serves as a convex portion close to the seat plate 15. When the string-like operation member 25 is pulled when the shutter curtain 17 is opened, the operation tip 21 strikes the seat plate 15 and the closing force is carried on the seat plate 15 via the operation tip 21 . That is, the lever 19 is prevented from being damaged due to an excessive tensile force. Further, the operation tip portion 21 is normally in a non-contact state with the seat plate 15 by providing a gap between the operation tip portion 21 and the seat plate 15. As a result, noise such as contact noise (chattering noise) and abnormal noise due to contact between the operating tip 21 and the seat plate 15 is prevented.

  A gripping body 31 is attached to a string end 29 opposite to the lever 19 of the string-like operation member 25. The gripping body 31 may use an iron material or may be provided with a magnet inside. Compared to the string-like operation member 25 which is difficult to transmit a pulling force by providing a grip ball-shaped grip body 31 at the string end portion 29, for example, with respect to the thin string-like operation member 25 having flexibility. A tensile force can be applied. Thus, the string-like operation member 25 can be easily held, and the lever 19 can be rotated by pulling the string-like operation member 25.

  The string-like operation member 25 is made of a magnetic body 33. As the magnetic body 33, a wire using an iron material can be used. On the other hand, the belt-like member 27 is formed of a magnetized sheet 35. The magnetized sheet 35 is provided on the surface of the guide rail 13 on the indoor side. For example, you may fix to the side of the groove | channel of the guide rail 13, an indoor surface, or the inner surface (inner wall surface) of the guide rail 13. FIG. In addition to bonding and screwing, the magnetized sheet 35 may be screwed to the guide rail 13 after being fixed to a rail-shaped holding material.

  In the structure of this embodiment, the band-shaped member 27 having a large surface area becomes the magnetized sheet 35 as compared with the string-like operation member 25 having a small wire diameter and a small surface area. In other words, the string-like operation member 25 can be made thin and inconspicuous. Thereby, a magnetic attraction force can be applied to the belt-like member 27 having a large area, and a large magnetic adhesion force can be obtained.

FIG. 5A is a perspective view of the winding device when the string-like operation member is extended, and FIG. 5B is a perspective view of the winding device when winding.
The string-like operation member 25 is wound around a winding device 37 that allows the string-like operation member 25 to be wound and unwound. The winding device 37 is attached to the opening / closing body 17, and the string-like operation member 25 fed out from the winding device 37 is inserted into the operation distal end portion 21 of the lever 19. In order to support the string-like operation member 25, the operation tip portion 21 may be formed in a hook shape, or a through hole may be formed. Furthermore, it is good also as a pipe shape which the string-like operation member 25 can penetrate lever 19 itself. The winding device 37 may be attached to the lever 19.

  The string-like operation member 25 is fed out and taken up from the winding device 37, so that the length from the operation leading end portion 21 through the string-like operation member 25 to the string end portion 29 can be varied. Therefore, the string-like operation member 25 from the operation distal end portion 21 can be set to a desired length by adjusting the feeding amount of the string-like operation member 25 from the winding device 37.

  The winding device 37 can be provided on the seat plate 15 separately or integrally with the locking device 23. In a configuration in which the winding device 37 is provided on the seat plate 15 separately from the locking device 23, for example, in a configuration in which the winding device 37 is fixed so as to overlap the locking device 23 already provided on the seat plate 15, the winding device The string-like operation member 25 between the operation tip portion 21 and the operation tip portion 21 can be arranged in parallel with the seat plate 15. On the other hand, in a configuration in which the winding device 37 is provided integrally, for example, in a structure in which the winding device 37 is built in the locking device 23, the exposed length of the string-like operation member 25 is from the locking device 23 to the operation tip 21. It becomes the distance. Therefore, in the case of a separate structure, the string-like operation member 25 can be arranged in a straight line along the seat plate 15 and the winding / unwinding of the winding device 37 becomes smooth. Further, it can be retrofitted to an existing locking device, that is, the winding device 37 can be arranged and configured with respect to the existing shutter device. In addition, when the winding device 37 and the locking device 23 are integrated, the distance of the string-like operation member 25 exposed between the operation tip portion 21 can be reduced, and interference with other members is eliminated to prevent erroneous unlocking. can do.

  The string-like operation member 25 has a disadvantage if it is too short or too long. In the opening / closing body device having the present locking device, the length of the string-like operation member 25 is longer than the distance from the operation distal end portion 21 to the guide rail 13, and the opening / closing body opening width dimension W and the guide rail 13 length dimension H. Is set to be shorter than a half ((W + H) / 2) of the sum of (W + H). Therefore, the string-like operation member 25 does not reach the guide rail 13 and the string-like operation member 25 can be prevented from becoming unnecessarily long during the closing operation and the opening operation of the shutter curtain 17. As a result, the string-like operating member 25 can be magnetically attached to either the left or right guide rail 13 and the string end 29 of the string-like operating member 25 can be operated even when the opening / closing body 17 is closed or opened. It can arrange | position in the guide rail center part suitable for.

  The winding device 37 preferably has a feeding regulation function and a winding function. Thereby, the string-like operation member 25 can be drawn out by a necessary length. In this case, the winding device 37 is preferably provided with a winding button 77 and a string fixing switch 79. That is, by operating the cord fixing switch 79, the feeding and winding of the cord-like operation member 25 are restricted, and the cord-like operation member 25 can be automatically wound by pressing the winding button 77.

FIG. 6A is a perspective view of a regulation state of the feeding restriction device, and FIG. 6B is a perspective view of a regulation release state of the feeding regulation device.
The feeding regulating device 39 that regulates the feeding of the string-like operation member 25 includes a string fixing switch 79 between a pair of string penetrating pieces 81, 81 with a rotation shaft 83 in the same direction as the insertion direction of the string-like operation member 25. Is rotatably arranged, and the string-like operation member 25 is passed through the switch board 79a. As a result, as shown in FIG. 6A, by rotating the string fixing switch 79 in a state where the string-like operation member 25 is bent, the passage of the string-like operation member 25 can be regulated by friction. As shown in (b), the regulation can be released by rotating the string fixing switch 79 so that the string-like operation member 25 becomes a straight line.

  In this way, the string-like operation member 25 is fixed by the feeding restriction device 39, so that the string-like operation member 25 is not drawn from the winding device 37 due to the pulling force during operation. As a result, the string-like operation member 25 can be reliably fixed by the feeding restricting device 39, and a change in the set length of the string-like operation member 25 can be prevented.

FIG. 7 is a perspective view of the winding and regulating device.
Further, the take-up device 37 may be provided with a take-up and restriction device 41 that takes up the fed string-like operation member 25 and regulates the take-up and delivery of the string-like operation member 25. In this case, the string fixing switch 79 can be omitted. The winding and regulating device 41 includes a winding bobbin 85 that is urged in the winding direction a and the axial direction b by a winding coil spring 83. The winding button 77 is protruded from the flange portion of the winding bobbin 85. A plurality of locking projections 87 are arranged at equal intervals in the circumferential direction on the collar portion. On the other hand, a locking recess (not shown) that engages with the locking projection 87 is formed on the inner surface of the case of the winding and regulating device 41.

  Thereby, if the winding bobbin 85 is urged by the winding coil spring 83 and the locking projection 87 is locked in the locking recess, the winding / unwinding rotation of the winding bobbin 85 is restricted. On the other hand, when the take-up button 77 is pressed against the urging force of the take-up coil spring 83, the lock projection 87 and the lock recess are unlocked, and the string-like operation member 25 is automatically wound by the take-up coil spring 83. Or manual feeding is possible.

  Thus, if the winding and regulating device 41 is set to the winding and feeding mode, the length of the string-like operation member 25 can be arbitrarily set, and if the winding and regulating device 41 is set to the regulated mode, the operation is performed. It is possible to prevent the string-like operation member 25 from being fed out at the time. As a result, the winding device 37 has a winding function and a regulating function, and the length adjustment and fixing of the string-like operation member 25 can be performed with one device.

Next, the operation of the opening / closing body device having the locking device having the above configuration will be described.
FIG. 8 is a perspective view of the magnetic attachment / operation state of the string-like operation member when the opening / closing body is closed, and FIG. 9 is a perspective view of the magnetic attachment / operation state of the string-like operation member when the opening / closing body is opened.
In the opening / closing body device having the locking device, the seat plate 15 is disposed at the lowermost end of the building opening 57 when the shutter curtain 17 is closed. The string-like operation member 25 led out from the winding device 37 provided in the locking device 23 is held by the magnetic attractive force on the magnetized sheet 35 via the operation tip 21 of the lever 19. In order to open the shutter curtain 17, by holding the grip body 31, the string-like operation member 25 is detached from the magnetized sheet 35 and pulled vertically upward, so that the shutter 19 is unlocked and rotated while the lever 19 is unlocked. Pull up.

  On the other hand, when the shutter curtain 17 is opened, the seat plate 15 is disposed on the lower surface of the storage case 59. The string-like operation member 25 led out from the winding device 37 provided in the locking device 23 is held by the magnetic attractive force on the magnetized sheet 35 via the operation tip 21 of the lever 19. In order to close the shutter curtain 17, by holding the grip body 31, the string-like operation member 25 is detached from the magnetized sheet 35 and pulled vertically downward to pull down the shutter curtain 17.

  As described above, in the opening / closing body device having the locking device, the slack portion from the operation tip 21 to the string end 29 when the string-like operation member 25 is set to a length that can be arranged at an easily operable position, It becomes possible to attach to the seat plate 15 and the guide rail 13 by being magnetically attached to the belt-like member 27 provided along the guide rail 13. The string-like operation member 25 is not magnetically attached along the guide rail 13 and is not obstructed when it is not necessary. Since it sticks along the guide rail 13 along the longitudinal direction, it does not obstruct the appearance in both the open state and the closed state.

  Therefore, according to the opening / closing body device having the locking device, the string-like operation member 25 is supported on the operation tip 21 of the lever 19, the belt-like member 27 is attached along the guide rail 13, and the string-like operation member 25 and the belt-like member are attached. Since the members 27 are configured to be magnetically attached to each other, the string-like operation member 25 can be disposed within the reach of the hand during the opening operation, for example, while not disturbing when not necessary. As a result, appearance, safety, and operability can be improved.

  Further, the length of the string-like operation member 25 can be adjusted to a desired length by the winding device 37. Even if the position of the locking device 23 is changed, it can be appropriately handled.
