  In this conventional locking device, an extending member extending from the handle member to the locking means side is provided, and by moving the extended member relative to the shutter curtain by manual operation of the handle member, Since the locking and unlocking of the locking means can be switched, the extending member is an important member. For this reason, it is required to protect the extending member from an external force or the like, and a device for realizing this is required.

  An object of the present invention is to provide a locking device for an opening / closing device which can protect an extended member extending from a manual operation member such as a handle member to the locking means side from an external force or the like.

  The locking device of the opening / closing apparatus according to the present invention includes an opening / closing body, a guide member for guiding opening / closing movement of the opening / closing body, locking means for locking movement of the opening / closing body relative to the guide member, and the opening / closing A hand-operated member disposed on the body so as to be manually operable, and extends from the hand-operated member toward the locking means, and is movable with respect to the opening / closing body by manual operation of the hand-operated member. And an extension member for switching between locking and unlocking of the locking means, characterized in that it has a cover member that covers the extension member. .

  According to this locking device, since the extending member extending from the manual operation member to the locking means side is covered by the cover member, the extending member can be protected from external force or the like by the cover member, The extension member can be prevented from being damaged or deformed. In addition, since the cover member can prevent foreign matter such as dust from entering between the extending member and the opening / closing body, the extension member can be smoothly moved with respect to the opening / closing body by manual operation of the manual operation member. Can do.

  In this locking apparatus, the locking of the opening / closing body relative to the guide member performed by the locking means may be locking for opening movement, locking for closing movement, or locking for both opening movement and closing movement.

  Further, the manual operation performed on the manual operation member may be a slide operation in the width direction of the opening / closing body, a rotation operation, or an operation in which these are combined. Further, the movement performed by the extending member when the manual operation member is manually operated may be a sliding movement in the width direction of the opening / closing body or the like, or may be a movement in which these are combined.

  Furthermore, the manual operation member may be any member as long as it is a member operated by hand. An example of the manual operation member is a manual operation member that is manually held by a person to open and close the opening / closing body and can be reciprocated toward the locking means by manual operation. Another example of the manual operation member is a lock means in which a key operated by hand is inserted, and the advance / retreat member is advanced / retracted by a rotation operation of the key by hand, and the advance / retreat member can slide relative to the opening / closing body By connecting the extending members, the locking means can be switched between locking and unlocking by the movement of the advancing / retreating member and the extending member by the key turning operation. The lock means may be provided with a member such as a thumb turn that is directly operated by hand to move the advance / retreat member forward / backward together with or in place of the key. Then, the advancement / retraction member of the lock means that is a manual operation member may be advanced / retracted only by a member such as a thumb turn, and may be performed by both a member such as a thumb turn and a key. Or may be performed only by a key.

  In the locking device of the opening / closing apparatus according to the present invention, when the hand operating member is the handle member, the size of the cover member may be a size that covers the handle member. According to this, the cover member can also protect the handle member from external force and the like, and since foreign matter such as dust can be prevented from entering between the handle member and the opening / closing body, the locking means can be locked and unlocked. When the handle member is manually operated in order to switch between the two, the movement of the handle member relative to the opening / closing body can be made smooth.

  In this way, when the cover member is also covered by the cover member and the handle member can be manually operated from the outside of the cover member, a window hole is formed in the cover member at a position corresponding to the handle member, What is necessary is just to enable it to operate a handle member by the hand inserted in this window hole from the outer side.

  Further, in the case where the lock member having a lock member that is movable forward and backward toward the handle member and prevents the handle member from moving by reaching the advance position is disposed on the opening / closing body, the cover member is It is good also as what covers the locking member of a locking means.

  According to this, the cover member can also protect the lock member of the lock means from external force and the like, and foreign matter such as dust can be prevented from entering between the lock member and the opening / closing body. The body can move forward and backward smoothly.

  In the present invention, the locking means and the structure and form for locking and unlocking the locking means are arbitrary. One example is that a locking member such as a latch member is provided on the opening and closing body side, and a locked member such as a latch receiving member that is locked by the locking member is provided on the guide member side. And when the locking member is moved to the locked member side when the locking member is connected to the handle member via the extending member. The locking member is locked by the locking means by locking the locking member, and the locking member moves to the opposite side to the locked member side via the extending member by the movement of the handle member. The locking by the locking means is to be unlocked.

  Another example of the structure and type for locking and unlocking the locking means and the locking means is that the locking means is disposed on the locking member such as a latch member disposed on the opening / closing body, and on the guide member. And an end of the extending member on the side of the locking means, which is slidable with respect to the opening and closing body, and is locked. The slide member for locking the locking member to the locked state by preventing the locking member from being unlocked by sliding to the means side is connected, and this sliding member is locked by manual operation of the handle member. By sliding to the side opposite to the means side, the locking of the locking member with respect to the locked member can be released.

  When the locking means and the structure and type for locking and unlocking the locking means are configured in this way, the cover member may cover at least a part of the slide member.

  According to this, at least a part of the slide member can be protected from an external force or the like by the cover member, and foreign matter such as dust can be prevented from entering between the slide member and the opening / closing body. The slide with respect to the opening / closing body can be made smooth.

  In the present invention, the cover member may be provided with a suppressing portion for suppressing the movement of the handle member in a direction different from the moving direction of the handle member by manual operation.

  According to this, the cover member can suppress the movement of the handle member in a direction different from the original movement direction by the manual operation. For this reason, the cover member moves the handle member in the original movement direction. This also serves as a guide member for causing the cover member to have multiple functions.

  Here, when the handle member is moved in a direction different from the original movement direction by the manual operation, for example, when the original movement direction by the manual operation of the handle member is the width direction of the opening / closing body, the handle member is opened / closed body This means moving in an opening / closing movement direction, a thickness direction of the opening / closing body, and a direction inclined with respect to these directions.

  As described above, an example of providing the cover member with a suppressing portion for suppressing the floating of the handle member in a direction different from the direction in which the handle member is moved manually is as follows. The above-mentioned suppressing portion that is formed of a channel material provided with a flange portion and suppresses the looseness of the handle member disposed inside the cover member is a flange portion.

  According to this, the effect that the cover member provided with the said suppression part can be easily formed with a channel material is acquired.

  And when the dimension of the handle member in the interval direction between these flange parts is smaller than the distance dimension between the flange parts at both ends of the web part, one of the handle member and the flange part is the other You may provide the stopper part extended to the side. According to this, the difference in the above dimensions can be eliminated by these stopper portions, and the looseness of the handle member inside the cover member can be more reliably suppressed.

  Moreover, in this invention, the structure for attaching a cover member to the said opening / closing body is arbitrary. For example, the locking means includes a locking member disposed on the opening / closing body via a base member, and a locked member disposed on the guide member and locked by the locking member. When the body is provided with locking means having a locking member that can move back and forth toward the handle member and that prevents the handle member from moving by reaching the forward position, the cover member is Coupling to the base member and the locking means;

  According to this, the cover member is attached to the opening / closing body via the base member and the locking means, and these base member and locking means are also used as members for attaching the cover member to the opening / closing body. The cover member can be attached to the opening / closing body without increasing the number of members by effectively utilizing the members.

  Of course, you may couple | bond a cover member directly with the member which comprises the opening / closing body.

  The locking device of the present invention described above includes various shutter devices such as a shutter device whose opening and closing body is a shutter curtain, an awning device whose opening and closing body is a curtain for sunshade and rain protection, and a sliding door device. It can be applied to a switchgear. Further, when the opening / closing device to which the locking device according to the present invention is applied is a shutter device in which the opening / closing body is a shutter curtain, the shutter device opens and closes an opening such as an entrance / exit and a window with the shutter curtain. It may be an opening shutter device, a garage shutter device, a storage shutter device, or a vehicle-mounted shutter device mounted on the loading platform of a vehicle such as a truck. It may be a shutter device (including one for an elevator).

  When the locking device according to the present invention is applied to a shutter device, the shutter device may be a shutter device that winds and stores the shutter curtain on a winding shaft, and stores the shutter curtain without winding it on the winding shaft. For example, a shutter device that stores the shutter curtain as it is or slightly deformed into a curved shape, such as an overhead door, and connects each shutter curtain component formed by a panel or the like. The shutter device may be folded and stored while being stored while being separated from each other.

  In a case where the locking device according to the present invention is applied to a shutter device that winds and stores a shutter curtain on a winding shaft, the extending member is covered by the cover member. The cover member can prevent the extending member from hitting the constituent members of the shutter curtain.

  When the locking device according to the present invention is applied to a shutter device that winds and stores a shutter curtain on a winding shaft, the structure and type of the winding shaft are arbitrary. That is, the take-up shaft may be formed by connecting one shaft or a plurality of shafts in series, and for winding and feeding the shutter curtain around the outer periphery of the fixed shaft arranged at the center. The rotating member may be rotatably arranged. In the latter case, the rotating member includes a plurality of wheels rotatably fitted on the outer periphery of the fixed shaft and a bar-shaped connection that connects these wheels spaced apart in the axial direction of the fixed shaft. It may be formed including a member, or may be formed including these wheels and a pipe-like member that is fixedly fitted to the outer periphery of these wheels to couple the wheels together.

  The shutter curtain including the seat plate may be formed entirely or substantially entirely by slats, may be formed by a panel, may be formed by a sheet, and is formed by a pipe connected by a link. Or may be formed of a net, or a composite of a plurality of different types of members, for example, a composite of a plurality of these, such as a slat and a pipe. Good.

  Furthermore, the present invention can be applied to a manual shutter device in which the shutter curtain is opened and closed by manual operation with a handle member, and the shutter curtain can be opened and closed by a driving force of an electric motor or the like. It can also be applied to both manual and automatic shutter devices with functions, and the movement of one of the shutter curtain opening and closing movements uses the spring force of the return spring accumulated during the other movement. The present invention can also be applied to a spring force assist type shutter device that is used as an assist force.

  In addition, the locking device according to the present invention can be used to open / close the shutter curtain in both a shutter device in which the opening / closing movement direction of the shutter curtain is vertical and a shutter device in which the opening / closing movement direction of the shutter curtain is horizontal. The present invention can also be applied to a shutter device in which the moving direction is inclined with respect to the vertical direction or the horizontal direction.

  According to the present invention, it is possible to obtain an effect that the extending member extended from the manual operation member such as the handle member to the locking means side can be protected from the external force or the like by the cover member.

  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated based on drawing. FIG. 1 is an overall front view of a manual opening shutter device which is an opening / closing device provided with a locking device according to the present embodiment. It shows the time when the shutter curtain 1 which is the body is fully closed.

  A shutter curtain 1 that opens and closes an opening 2 that is an entrance of a building by moving up and down is provided on a guide rail 4 that is a guide member attached to a housing 3 such as a building wall on the left and right sides of the opening 2. Both ends in the width direction, which are both ends, are slidably inserted. A shutter case 5 is provided in the upper part of the opening 2, and a winding shaft 6 is supported by a pair of left and right brackets 7 inside the shutter case 5 so as to be rotatably accommodated. The upper end of 1 is joined. The end of the shutter curtain 1 on the closing side, in other words, the lower end of the shutter curtain 1 is a seat plate 8, and the upper end of the seat plate 8 has a number of slats 9 that form most of the shutter curtain 1. Therefore, the shutter curtain 1 is a slat type in which the main part is formed by connecting a large number of slats 9.

  The shutter curtain 1 is raised by being guided by the pair of guide rails 4, and the seat plate 8 forms a lower surface of the shutter case 5 and is provided with a slit through which the shutter curtain 1 is inserted vertically. Until the shutter curtain 1 is wound on the winding shaft 6, the shutter curtain 1 fully opens the opening 2. Further, when the leading end of an operation rod such as an engagement rod is engaged with the seat plate 8 and is manually pulled down, the shutter curtain 1 is drawn out from the take-up shaft 6 while rotating the take-up shaft 6. The shutter curtain 1 closes the opening 2 as shown in FIG. 1 by closing and moving, and the seat plate 8 landing on the floor 2A of the opening 2.

  Thus, when the shutter curtain 1 is extended from the winding shaft 6 and moved to close, a return spring (not shown) built in the rotating winding shaft 6 is accumulated, so that the fully closed position or a halfway position where the shutter curtain 1 is fully closed is accumulated. When the shutter curtain 1 stopped at is lifted to be opened and moved manually, the shutter curtain 1 can be lifted slightly by assisting the rotation of the winding shaft 6 by the accumulated pressure of the return spring. .

  Among a large number of slats 9 forming the shutter curtain 1, a predetermined slat 9A, that is, a slat 9A substantially at the waist level when the shutter curtain 1 is fully closed has a shutter In order to be able to open and close the curtain 1 manually, the synthetic resin handle member 10 which is a manually operated member that can be hooked is orthogonal or substantially orthogonal to the vertical direction. Two shutter curtains 1 are provided in the width direction. The slat 9 </ b> A is also provided with a lock means 11 at the center in the width direction of the shutter curtain 1 between the two handle members 10.

  FIG. 2 is a rear view of the shutter curtain 1 showing the slat 9A provided with a hand-operated member 10 that is a manually operated member and the portions of the slats 9 above and below the slat 9A. Lock means 11, which is partially penetrated through the slat 9 </ b> A, is fastened by a fastening tool 12 such as a rivet at the central part in the length direction of the slat 9 </ b> A that is the central part in the width direction of the shutter curtain 1. In addition, in the slat 9A, two handle members 10 are arranged so as to partially penetrate the slat 9A at positions equidistant from the lock means 11 on the left and right. As will be described later, these handle members 10 are arranged on the slats 9 </ b> A so as to be reciprocally movable in the left-right direction that is the width direction of the shutter curtain 1. Further, locking members 13 are arranged at both ends of the slat 9A in the length direction, and are each a member for each handle member 10, and these locking members 13 serving as latch members are shown in FIG. The locking member 14 which is a latch receiving member attached to the inside of the guide rail 4 shown in FIG. 5 is used to lock the opening movement which is the upward movement of the shutter curtain 1 reaching the fully closed position. The locking means 15 is constituted. This locking means 15 is provided for each handle member 10.

  As shown in FIG. 2, a cover member 16 is disposed on the back surface of the slat 9 </ b> A between the locking means 11 and the locking member 13. By these cover members 16 provided, members disposed on the back surface of the slat 9A and connecting the locking means 11 and the handle member 10 and members disposed between the handle member 10 and the locking member 13 Is covered. The cover member 16 is fixed to the lock means 11 with a fixing tool 17 such as a screw, and is formed by bending a part of the base member 18 shown in FIG. 17 in which the locking member 13 is arranged. The bracket portion 18A is also fastened with a fastening tool 19 such as a screw (see FIG. 2). The base member 18 is fixed to the slat 9A with a fastening tool 20 (see FIG. 17) such as a rivet, and a bent portion 18B (see FIGS. 17 and 18) at the tip of the base member 18. It is combined with the slat 9A also by pinching.

  For this reason, the cover member 16 is attached to the slat 9A via the lock means 11 and the base member 18, and the lock means 11 and the base member 18 also serve as members for attaching the cover member 16 to the slat 7A. .

  As shown in FIG. 2, an end member 21 having a portion 21A that contacts the end surface of the cover member 16 is disposed at the end of each cover member 16 on the lock means 11 side, and the main body portion is the cover member 16 and the lock means. These end members 21 inserted between the main body 11 and the end member 21 are fixed to the locking means 11 together with the cover member 16 by the fastener 17 and cut by the portion 21A. The end face of the metal cover member 16 serving as a cut surface is not exposed to the outside.

  Further, each cover member 16 is formed with a window hole 16A for exposing a part 10A of the handle member 10 to the outside, and these window holes 16A are long in the left-right direction. The part 10A can reciprocate in the left-right direction with respect to the slat 9A and the cover member 16 while always facing the outside through the window hole 16A.

  As shown in FIG. 2, end structures 22 made of synthetic resin are attached to both ends in the longitudinal direction of each slat 9 except for the slats 9 </ b> A. As shown in FIG. 3 showing the side shape, the engagement groove 24A is engaged with the first end member 23 in which the slit 23A into which the slat 9 is inserted is formed, and the engagement protrusion 23B of the first end member 23. The second end member 24 is coupled to the first end member 23 by a coupling tool 25 such as a rivet. When the shutter curtain 1 composed of the slats 9 is wound around the winding shaft 6 shown in FIG. 1, the contact between the slats 9 causes the dimension of the shutter curtain 1 to protrude to both sides in the thickness direction. The slat 9A in which the handle member 10 and the lock means 11 are disposed and the other slats 9 are prevented from coming into contact with each other, and the cover member 16 of the slat 9A is also prevented. And the end structure 22 are prevented from contacting each other.

  FIG. 4 is a rear view of the slat 9A shown in FIG. 2 and is a view in which the cover member 16 described in FIG. 2 is removed. The lock means 11 has a pair of left and right lock members 31 that are upside down. Like the lock members 31, the lock means 11 has a pair of left and right sides that are upside down. The rack member 30 is also arranged. Each rack member 30 is provided for each handle member 10, and these rack members 30 are connected to the handle member 10 via short bar members 32 that are connecting members.

  The end portions of the extending members 34 are connected to the end portions of the respective handle members 10 opposite to the bar members 32, and these extending members 34, which are long members, are separated from the handle members 10. The locking member 15 extends toward the locking member 13, and is connected to the slide member 33 at the tip. The cover member 16 covers the rack member 30, the lock member 31, the handle member 10 excluding the part 10A, the bar member 32, the extending member 34, and the slide member 33.

  FIG. 5 is a front view of the locking means 11 as in FIG. 1, and FIG. 6 is a plan sectional view showing the internal structure of the locking means 11. Next, the structure and operation of the locking means 11 will be described.

  A rotor 41 is fitted to the outer peripheral portion of the rotary plug 40 of FIG. 6 having the key hole 40A into which the plate key shown in FIG. 5 is inserted. When the plate key is inserted into the key hole 40A, the rotary plug 40 rotates. The first tumbler (not shown) that has stopped is retracted, and the second tumbler (not shown) that connects the rotary plug 40 and the rotor 41 protrudes. For this reason, the rotary plug 40 and the rotor 41 can be rotated by manual operation of the plate key inserted into the keyhole 40A. A pinion member 42 is coupled to the rotor 41. As shown in FIG. 7, the rack portion 31A of the pair of lock members 31 described above meshes with the pinion member 42. The upper and lower sides of the pinion member 42 arranged between the rack portions 31A are engaged with each other on the upper and lower sides. When the rotor 41 is rotated 180 degrees in one direction by the rotation operation of the plate key, the pair of lock members 31 are shown in FIGS. 7 and 11 (FIG. 7 is a front view of the internal structure of the lock means 11 through the pinion member 42. 11 is a rear view of the lock unit 11.) is changed to the state of FIGS. 8 and 12, and the rotor 41 is further rotated 180 degrees in the other direction by rotating the plate key. Then, the pair of lock members 31 returns from the state of FIGS. 8 and 12 to the state of FIGS. 7 and 11.

  The plate key is operated from the front side of the shutter curtain 1, but as shown in FIG. 6, it is manually rotated on the back surface of the lock means 11 protruding to the back side of the shutter curtain 1. A rotation operation member 44 (see also FIGS. 11 and 12) made of synthetic resin is provided as a thumb turn member to be operated. The rotation operation member 44 penetrates through the case member 45 shown in FIG. 6 of the locking means 11 and is coupled to the rotor 41, and is exposed to the outside of the case member 45 as shown in FIGS. In the portion of the rotating operation member 44 that is provided, two finger-hanging portions 44A that can be rotated by putting fingers are provided at a separation angle of 180 degrees. As shown in FIG. 6, a recessed portion 47 into which a small protrusion 46 formed on the case member 45 is fitted is formed on the surface of the finger hanging portion 44 </ b> A that faces the case member 45.

  When the pair of lock members 31 are in the state shown in FIGS. 7 and 11, the rotary operation member 44 is rotated 180 degrees while the small protrusions 46 are moved over by elastic deformation of the finger-hanging portion 44 </ b> A, and then the recess portion When the small protrusion 46 on the opposite side is re-fitted to 47, the rotor 41 also rotates 180 degrees with respect to the rotary plug 40, so that the pair of lock members 31 are rotated by the rotation of the pinion member 42 coupled to the rotor 41. 8 and 12 are obtained. When the rotation operation member 44 is rotated 180 degrees to the opposite side, the pair of lock members 31 returns to the state shown in FIGS.

  That is, the operation of the lock means 11 for moving the pair of lock members 31 to the left and right is performed from the front side of the shutter curtain 1 by a plate key and from the back side of the shutter curtain 1 by a manually operated rotation operation member 44. Yes.

  When the pair of lock members 31 reach the retracted position shown in FIGS. 7 and 11 and the advanced position shown in FIGS. 8 and 12, the small protrusions 46 are fitted in the recesses 47. Even if an unexpected external force or the like is applied to 11, the rotation operation member 44 can be prevented from rotating.

  7 and 8, the teeth of the rack portion 31A of the pair of lock members 31 have a trapezoidal shape or the like, and the teeth of the pinion member 42 meshing with the rack portion 31A are For this reason, the rotational driving force from the pinion member 42 is transmitted to the pair of lock members 31, but these lock members 31 reach the retracted position in FIG. 7 and the advanced position in FIG. The sliding drive force from these lock members 31 is not transmitted to the pinion member 42.

  As shown in FIG. 6, another pinion member 48 is accommodated in the lock means 11, and this pinion member 48 is disposed coaxially with the pinion member 42. 48 is fitted to the outer periphery of the rotor 41 described above, and the pinion member 48 is rotatable with respect to the rotor 41. Further, as shown in FIG. 9, the rack portion 30 </ b> A of the pair of rack members 30 described in FIG. 4 is engaged with the pinion member 48. These rack portions 30A are inserted into the case member 45 of the lock means 11, and these rack portions 30A are opposite to the pinion members 48 disposed between these rack portions 30A. The top and bottom are meshed. Since the teeth of the rack portion 30A and the teeth of the pinion member 48 are teeth of a normal shape, when one pair of rack members 30 has reached an arbitrary left and right position, one of the rack members 30 When a slide driving force in the left-right direction is applied to the member 30, the pinion member 48 rotates about the rotor 41, so that the other rack member 30 has the above-described structure as shown in FIG. One rack member 30 is slid in the opposite direction.

  As described with reference to FIG. 4, one rack member 30 of the pair of rack members 30 is connected to one handle member 10 of the two handle members 10 by the bar member 32, and the other rack member 30 is Since the bar member 32 is connected to the other handle member 10, when one of the pair of handle members 10 is moved with respect to the shutter curtain 1, this movement is caused by the pair of rack members 30 and the pinion. It is transmitted to another handle member 10 via the member 48. For this reason, the two handle members 10 can be moved by operating the one handle member 10.

  For this reason, a rack and pinion type in which two handle members 10 are connected to each other by the bar member 32, the pair of rack members 30, and the pinion member 48, and these handle members 10 can be moved in conjunction with each other. The handle member interlocking means 50 (see FIGS. 9 and 10) is configured. Further, the interlocking means 50 is a reversible handgrip member interlocking means for transmitting the movement of one handgrip member 10 to the other handgrip member 10 by reversing the moving direction.

  Since the rack portion 30 </ b> A and the pinion member 48 of the pair of rack members 30 are disposed inside the locking means 11, the handle member interlocking means 50 is a means penetratingly disposed inside the locking means 11. For this reason, even if the lock means 11 is disposed between the two handle members 10 that are interlocked with each other, the lock means 11 does not become an obstacle when the handle member interlocking means 50 is disposed, and the lock means 11 and the handle member The interlocking means 50 is reasonably disposed on the shutter curtain 1.

  A stopper portion 31B bent at a right angle or a substantially right angle is provided at the distal end portion of the pair of lock members 31 described with reference to FIGS. 7 and 8 and FIGS. 11 and 12, and the above-described plate key operation or rotation operation member 44 is provided. When the lock member 31 reaches the forward position shown in FIGS. 8 and 12 by the operation of the above, the stopper portions 31B are bent portions 30B to which the bar members 32 of the rack member 30 are coupled (see FIG. 12). ), Each handle member 10 is moved inward in the width direction of the shutter curtain 1 to unlock the locking means 15 described in FIGS. 2 and 21, as will be described later. In this case, the bent portion 30B of the rack member 30 trying to move integrally with the handle member 10 via the bar member 32 is in contact with the stopper portion 31B of the lock member 31. As described above, the pinion member 42 is not rotated by the slide driving force from the lock member 31 and the lock member 31 remains stopped at the forward position. The rack member 30 is prevented from moving by the lock member 31, and the respective handle members 10 cannot be moved inward in the width direction of the shutter curtain 1.

  For this reason, the movement of each handle member 10 is blocked by the locking means 11, and the locking of the shutter curtain 1 to the guide rail 4 by the locking means 15 is locked by the locking means 11.

  In the above structure, the pinion member 48 that is a constituent member of the handle member interlocking means 50 is housed inside the locking means 11 as described above, and when this pinion member 48 is the first pinion member, Inside the locking means 11, the pinion member 42 that is a constituent member of the locking means 11 is accommodated as the second pinion member 42. And since the 1st pinion member 48 is rotatably arrange | positioned at the said rotor 41 used as the rotation center member of the 2nd pinion member 42, the rotation center member of the 1st pinion member 48 is a 2nd pinion member. The structure of the handle member interlocking means 50 is simplified by that amount, and the number of necessary parts is reduced.

  FIG. 13 is a rear view of the handle member 10, and FIG. 14 is a plan view of the handle member 10. The handle member 10 includes a first portion 51 and a second portion 52 that are arranged side by side in the width direction of the shutter curtain 1 and are connected by a connecting portion 53, and the first portion 51 is a constituent member of the locking means 15. The second portion 52 is a portion on the inner side in the width direction of the shutter curtain 1, and the second portion 52 is a portion on the inner side in the width direction of the shutter curtain 1.

  The first portion 51 is disposed on the back surface side of the shutter curtain 1, that is, on the back surface side of the slat 9A, and the second portion 52 penetrates in the thickness direction of the shutter curtain 1 up to the middle portion of the thickness. 9A. Therefore, the second portion 52 has a front surface portion 52A disposed on the front side of the shutter curtain 1, and a back surface portion 52B disposed on the back surface side of the shutter curtain 1, and the first portion Reference numeral 51 denotes a back surface portion of the handle member 10 disposed on the back surface side of the shutter curtain 1. A flange portion 54 is formed on the surface portion 52A of the second portion 52, and a plurality of elastic portions facing the flange portion 54 and the shutter curtain 1 on the top, bottom, left and right of the back surface portion 52B of the second portion 52. 55 is provided.

  As shown in FIG. 13, these elastic portions 55 have a dimension in the opening / closing movement direction of the shutter curtain 1 that is orthogonal or substantially orthogonal to the width direction of the shutter curtain 1. It has a tapered shape that gradually increases inward. As shown in FIG. 14, a gap S corresponding to the thickness of the slat 9 </ b> A is provided between the elastic portion 55 and the flange portion 54.

  In the slat 9A, which is a constituent member of the shutter curtain 1, the middle portion of the thickness of the handle member 10 is disposed through the shutter curtain 1, and the entire first portion 51 and the back portion 52B of the second portion 52 are disposed in the shutter curtain. 1 is formed with an opening 56 for disposing on the back side. The length of the opening 56 in the width direction of the shutter curtain 1 is shorter than the entire length of the handle member 10 in the width direction of the shutter curtain 1, and the back surface portion 52B of the second portion 52 in the width direction of the shutter curtain 1. It is longer than the length by a distance L corresponding to the moving operation amount of the handle member 10. The vertical dimension of the opening 56 (the dimension in the opening / closing movement direction of the shutter curtain 1) is larger than the vertical dimension of the back surface 52B of the second portion 52, and the vertical dimension of the flange 54 and the elastic part 55 are It is smaller than the vertical dimension of the back part 52B including.

  Therefore, the handle member 10 is prevented from coming out of the opening 56 by the flange portion 54 and the elastic portion 55, and the handle member 10 is reciprocated in the width direction of the shutter curtain 1 by the distance L by the slat 9A. Arranged freely.

  On the front surface 52A of the second portion 52 of the handle member 10, a first handle recess 57 that is recessed toward the back side of the shutter curtain 1 is formed inside the flange portion 54, and the first portion 51 includes A second handle recess 58 that is recessed toward the front side of the shutter curtain 1 is formed.

  For this reason, the handle member 10 is moved to the shutter curtain 1 in order to unlock the locking means 15 by the handle recesses 57 and 58 provided on both sides in the thickness direction of the shutter curtain 1 in the handle member 10 as described above. The operation of moving the shutter curtain 1 in the width direction by the distance L and the operation of opening and moving the shutter curtain 1 along the guide rail 4 after unlocking the locking means 15 as will be described later. It can be done from the surface. The part 10 </ b> A of the handle member 10 facing the outside through the window hole 16 </ b> A of the cover member 16 shown in FIG. 2 is a second handle recess 58 formed in the first part 51.

  Before connecting the bar member 32 and the extending member 34 to the handle member 10, the opening 56 extends the middle portion of the thickness of the handle member 10 having the shape and size as described above through the opening 56. The operation of penetrating the slat 9A is performed as follows.

  After setting the handle member 10 to a horizontal posture or a posture inclined slightly with respect to the horizontal, the first portion 51 of the handle member 10 is inserted into the opening 56 from the front side of the shutter curtain 1 to the back side of the shutter curtain 1. Then, while changing the posture of the first portion 51 to the vertical posture as shown in FIG. 13, the first portion 51 is directed outward in the width direction of the shutter curtain 1, and the handle member 10 is moved. The shutter curtain 1 is shifted and moved from the inner side in the width direction to the outer side in the width direction. By this shifting, the back surface portion 52B of the second portion 52 of the handle member 10 is positioned at the position of the opening 56 as shown in FIG. To reach.

  In this way, when the back surface portion 52B of the second portion 52 reaches the position of the opening portion 56, the elastic portions 55 formed on the top, bottom, left and right of the back surface portion 52B come into contact with the edge portion of the opening portion 56. The elastic portion 55 is formed of a synthetic resin that is a material of the handle member 10, and this synthetic resin can be elastically deformed, and the elastic portion 55 is orthogonal or substantially orthogonal to the width direction of the shutter curtain 1. Since the taper shape in which the dimension of the opening / closing movement direction is gradually increased to the opposite side to the shifting movement direction, the elastic part 55 is elastically deformed at the edge of the opening 56 by this taper shape. Then, after the thickness of the elastic portion 55 is inserted into the opening 56 by pushing the handle member 10 in the thickness direction of the shutter curtain 10, in other words, the elastic portion 55 is opened. After the slats 9A is inserted into the gap S described above through the 6, the elastic portion 55 will be elastic restoring deformation.

  As a result, the middle part of the thickness of the handle member 10 including the first portion 51 is disposed through the opening 56 formed in the slat 9A. An operation of connecting the bar member 32 and the extending member 34 to the formed connecting portions 59 and 60 is performed. In this embodiment, this connecting operation is performed by inserting a bent part of the metal bar member 32 and the extending member 34 into the holes formed in the connecting portions 59 and 60 with screws or the like. It is done by combining. Further, after the operation of connecting the bar member 32 and the extending member 34 to the connecting portions 59 and 60, the cover member 16 shown in FIG. And an operation for coupling the base member 18 to the bracket 18A.

  15 is a cross-sectional view taken along line S15-S15 in FIG. 4 when the cover member 16 is attached to the slat 9A of the shutter curtain 1 via the lock means 11 and the base member 18 in this way. On the upper and lower surfaces of the handle member 10, stopper portions 65 extending in the up-down direction, which is the opening / closing movement direction of the shutter curtain 1, are formed. As shown in FIG. Then, it is formed in the first portion 51 of the handle member 10. Further, as shown in FIG. 15, the cover member 16 includes a pair of flange portions extending in the thickness direction of the shutter curtain 1 from the upper and lower end portions of the web portion 16 </ b> B in which the window hole 16 </ b> A is formed. It has a cross-sectional channel shape having 16C, and the inner surface of these flange portions 16C and the stopper portion 65 of the handle member 10 face each other in the vertical direction.

  For this reason, when the handle member 10 is moved in the width direction of the shutter curtain 1, the handle portion 10 can be prevented from swinging in the vertical direction by the stopper portion 65 coming into contact with the inner surface of the flange portion 16C. The moving operation of the handle member 10 performed manually can be performed while feeling a good feeling.

  That is, the fact that the handle member 10 tries to move in the opening / closing movement direction of the shutter curtain 1, which is different from the width direction of the shutter curtain 1, which is the original movement direction of the manually operated handle member 10, It will be restrained by the upper and lower flange portions 16 </ b> C of the member 16, whereby the handle member 10 can be moved in the width direction of the shutter curtain 1. For this reason, the upper and lower flange portions 16C of the cover member 16 are restraining portions for restraining the handle member 16 from moving freely in the opening / closing movement direction of the shutter curtain 1, and such restraining portions 16C are provided. The cover member 16 provided also serves as a guide member for guiding the handle member 10 in the width direction of the shutter curtain 1.

  16 is a cross-sectional view taken along line S16-S16 in FIG. 4 before the cover member 16 is attached. The extending member 34 that is a connecting member that connects the handle member 10 and the slide member 33 is formed of a channel material with a lip portion 34 </ b> A, and this extending member 34 that is in the width direction of the shutter curtain 1. A buffer member 66 made of a synthetic resin having elasticity is attached to one or a plurality of locations in the length direction of the slat 9A. The buffer member 66 has the extending member 34 and the slat 9A forming the shutter curtain 1. It is an intermediate member arranged between. The extension member 34 is attached to the buffer member 66 by causing the lip portion 34A to bite into the buffer member 66 and bonding the buffer member 66 to the extension member 34 with an adhesive.

  When the shutter curtain 1 is opened and closed by winding and unwinding the winding shaft 6 shown in FIG. 1, the buffer member 66 causes the extending member 34 that is a long member to move in the thickness direction of the shutter curtain 1. The extension member 34 can be prevented from coming into contact with the slats 9A by swinging to the slat 9A, and the generation of abnormal noise that occurs when the extension member 34 comes into contact with the slats 9A can also be prevented.

  Further, since the buffer member 66 is attached to the extending member 34, even if the extending member 34 moves in the width direction of the shutter curtain 1 with respect to the slat 9A by the operation of moving the handle member 10, the buffer member 66 does not move. Unlike the case where the buffer member 66 is attached to the slat 9A, the buffer member 66 does not deviate from the moving range of the extension member 34.

  Furthermore, in this embodiment, since the buffer member 66 bites into the lip portion 34A of the extending member 34, the buffer member 66 is firmly attached to the extending member 34 together with the bonding by the adhesive. Even if the extension member 34 is moved by the movement operation of the member 10, the extension member 34 is not detached from the extension member 34.

  An intermediate member similar to the buffer member 66 may be attached to the bar member 32 described above.

  17 and FIG. 18, which is a cross-sectional view taken along line S18-S18 of FIG. 17, is the above-described locking member 13 made of an alloy, for example, and the locked member 14 shown in FIG. And a contact portion 13B provided on the inner side in the width direction of the shutter curtain 1 than the locking portion 13A. Further, as shown in FIG. 17, the locking member 13 is vertically moved around a pin 70 installed between two bracket portions 18C formed on the base member 18 described in FIG. A coil spring 71 is wound around the pin 70, one end 71A of the coil spring 71 is locked to a rising portion 18D formed on the base member 18, and the other end 71B is locked. It is inserted into a hole 13 </ b> C formed in the member 13. Therefore, the locking member 13 is moved by the coil spring 71 to a rotation position where the extending direction of the triangular tongue-shaped locking portion 13A is horizontal or substantially horizontal as shown in FIG. The pin 70 is always elastically biased around the center.

  The slide member 33 described with reference to FIG. 4 is movably disposed on the base member 18, and the slide member 33 is arranged in the width direction of the shutter curtain 1 with respect to the locking member 13 as shown in FIG. 17. On the inner side, the base member 18 is disposed between two guide portions 18E formed one above the other by bending a part of the base member 18, and the slide member 33 is guided by the guide portions 18E so that the slide member 33 is disposed in the shutter curtain 1. It is movable in the width direction. Further, as can be seen from FIG. 18, the slide member 33 is a folded product of a plate material, and includes a first portion 81 on the outer side in the width direction of the shutter curtain 1 and a second portion 82 on the inner side in the width direction.

  A spring hook portion 82A is formed in the second portion 82, and the spring hook portion 82A is formed in the base member 18 and protrudes from the long hole 82B of the second portion 82 toward the slide member 33. Are opposed to each other in the width direction of the shutter curtain 1, and both end portions of a coil spring 83 serving as a tension spring are hooked on the spring hook portions 82A and 18F. For this reason, the slide member 33 is always elastically pulled outward in the width direction of the shutter curtain 1 with respect to the base member 18, whereby the first portion 81 of the slide member 33 is shown in FIG. 18. Thus, at the normal time, the locking member 13 reaches the lower position of the contact portion 13B.

  As shown in FIG. 17, the connecting portion 84 of the slide member 33 is connected to the end of the extending member 34 described in FIG. 4 on the outer side in the width direction of the shutter curtain 1. Since the inner end of the shutter curtain 1 in the width direction is connected to the handle member 10, the movement of the handle member 10 in the width direction of the shutter curtain 1 is transmitted to the slide member 33 via the extending member 34. In addition, the handle member 10 is always elastically biased toward the movement limit position on the outer side in the width direction of the shutter curtain 1 by the spring force of the coil spring 83.

  When the handle member 10 is manually moved to the inner side in the width direction of the shutter curtain 1 against the coil spring 83, the slide member 33 is also moved in the same direction as shown in FIG. When the hand is released, the handle member 10 returns to the movement limit position on the outer side in the width direction of the shutter curtain 1 by the spring force of the coil spring 83, and the slide member 33 is moved to the shutter as shown in FIG. Returning to the initial position outside the width direction of the curtain 1, the first portion 81 of the slide member 33 reaches the lower position of the contact portion 13 </ b> B of the locking member 13. At this time, as shown in FIG. 20, the locking member 13 in which the extending direction of the locking portion 13 </ b> A of the triangular tongue-shaped piece is the horizontal direction or the substantially horizontal direction is lower than the pin 70 as the center. Is prevented by the contact portion 13 </ b> B contacting the first portion 81 of the slide member 33.

  As shown in FIG. 18, the surface 81 </ b> A that faces the contact portion 13 </ b> B of the locking member 13 in the first portion 81 of the slide member 33 moves toward the outer side in the width direction of the shutter curtain 1. The surface 13D of the contact portion 13B facing the surface 81A is the same surface as the surface 81A. For this reason, the slide movement of the slide member 33 when the first portion 81 of the slide member 33 reaches the lower position of the contact portion 13B of the locking member 13 and the first portion 81 of the slide member 33 The slide movement of the slide member 33 that comes out of the lower position of the contact portion 13B and separates from the locking member 13 is performed smoothly.

  FIG. 21 shows a locked member 14 that constitutes the locking means 15 together with the locking member 13. The locked member 14 is attached to the inside of the guide rail 4 serving as a guide member for guiding the opening / closing movement of the shutter curtain 1, and the upper surface 14 </ b> A descends from the outside to the inside of the guide rail 4. The inclined surface is inclined, and the lower surface 14B is a horizontal plane or a substantially horizontal plane. Further, the upper surface 13E of the locking portion 13A of the locking member 13 is horizontal or substantially horizontal, and the lower surface 13F is directed from the outer side to the inner side of the guide rail 4 like the upper surface 14A of the locked member 14. The slope is inclined downward.

  When the shutter curtain 1 that has reached the fully open position is lowered and the locking portion 13A of the locking member 13 disposed on the shutter curtain 1 comes into contact with the locked member 14 from above, the locking portion 13A. Due to the action of the inclined lower surface 13F and the inclined upper surface 14A of the member 14 to be locked, the locking member 13 is arranged such that the locking portion 13A is in the state of the two-dot chain line 13A ′ in FIG. 71, the locking member 13 passes through the locked member 14 and the shutter curtain 1 reaches the fully closed position shown in FIG. Then, when the locking member 13 is returned and rotated downward by the spring force of the coil spring 71, the locking portion 13A returns to the horizontal state or the substantially horizontal state indicated by the solid line in FIG. 21, and the locking portion 13A. The upper surface 13 </ b> E faces the lower surface 14 </ b> B of the locked member 14.

  Thereafter, in order to open and move the shutter curtain 1, even if the hand is placed on the handle member 10 arranged on the shutter curtain 1 and the shutter curtain 1 is lifted as it is, the lower surface 14 </ b> B of the locked member 14 is not moved. The locking member 13 with which the upper surface 13E of the locking portion 13A abuts rotates downward because the abutting portion 13B of the locking member 13 abuts on the first portion 81 which is the stopper portion of the slide member 33. Can not. Therefore, at this time, the shutter curtain 1 is locked by the locking means 15 so that the movement of the shutter curtain 1 with respect to the guide rail 4 is locked. In other words, the locking member 13 of the shutter curtain 1 that is closed and moved downward is guided. Simultaneously with passing the locked member 14 of the rail 4, the shutter curtain 1 is automatically locked in the fully closed position by the locking means 15.

  In order to open and move the shutter curtain 1 from the fully closed position, at least one of the two handle members 10 arranged on the shutter curtain 1 is operated to move inward in the width direction of the shutter curtain 1. . As a result, each of the handle members 10 is moved inward in the width direction of the shutter curtain 1 by the rack-and-pinion-type handle member connecting means 50 described above, and each of the locking members 13 is arranged on the shutter curtain 1. The slide member 33 is also moved inward in the width direction of the shutter curtain 1 via the extending member 34, and the first portion 81 of the slide member 33 is detached from the contact portion 13 </ b> B of the locking member 13. When the shutter curtain 1 is lifted by a hand hung on the handle member 10 while maintaining this state, the locking member 13 in which the upper surface 13E of the locking portion 13A comes into contact with the lower surface 14B of the locked member 14 becomes the locking portion. 21A is rotated downward around the pin 70 until the state of the two-dot chain line 13A ″ shown in FIG. 21 is reached, and the locking member 13 passes through the locked member 14 by the upward movement of the shutter curtain 1. Will do.

  That is, at this time, the locking means 15 is unlocked. For this reason, the first portion 81 of the slide member 33 is moved against the locking member 13 by moving the handle member 10 inward in the width direction of the shutter curtain 1. The extending member 34 that can be detached from the contact portion 13B and the slide member 33 constitute an unlocking means 90 (see FIGS. 4 and 17 to 19) for unlocking the locking means 15. It is a member.

  In other words, when the handle member 10 is moved inward in the width direction of the shutter curtain 1 by manual operation, and the extending member 34 connected to the handle member 10 is also moved inward in the width direction of the shutter curtain 1, the locking means 15 is locked. Thus, the shutter curtain 1 can be opened and moved by lifting the shutter curtain 1 as it is with the hand hung on the handle member 10.

  Thereafter, the locking member 13 that has passed through the locked member 14 returns to the horizontal state or substantially horizontal state indicated by the solid line in FIG. 21 by the coil spring 71, and when the hand is released from the handle member 10, Each of the handle members 10 returns to the initial position on the outer side in the width direction of the shutter curtain 1 by the coil spring 83 described above, and each of the extending member 34 and the slide member 33 also returns to the initial position shown in FIG.

  Further, when the shutter curtain 1 has reached the fully closed position, the pair of lock members 31 of the locking means 11 described above are operated by the plate key from the front surface side of the shutter curtain 1 or the rear surface side of the shutter curtain 1. When the rotary operation member 44 is moved to the forward position shown in FIGS. 8 and 12, the handle member 10 is moved inwardly in the width direction of the shutter curtain 1 in FIG. As explained, the bending portion 30 </ b> B of the rack member 30 cannot be performed by contacting the stopper portion 31 </ b> B of the lock member 31. For this reason, the locking means 15 for locking the shutter curtain 1 in the fully closed position with respect to the guide rail 4 can be locked by the locking means 11. This lock is released by retracting the lock member 31 to the retracted position shown in FIGS. 7 and 12 by the operation of the plate key or the rotation operation member 44.

  According to the present embodiment described above, the extending member 34 extending from the handle member 10 serving as a manually operated member to the locking member 13 side of the locking means 15 is the cover 16 described above. Since the cover member 16 is covered, the extending member 34 can be protected from an external force or the like by the cover member 16, and when the shutter curtain 1 is wound around the winding shaft 6, the extending member 34 has a shutter. The cover member 16 can prevent the members such as the slats 9 constituting the curtain 1 from hitting, thereby preventing the extending member 34 from being damaged or deformed. Further, since the cover member 16 can prevent foreign matter such as dust from entering between the extending member 34 and the shutter curtain 1, smooth movement of the extending member 34 with respect to the shutter curtain 1 can be ensured. .

  Further, since the cover member 16 covers the portion of the handle member 10 protruding to the back side of the shutter curtain 1, this portion of the handle member 10 can be protected from external force or the like. The cover member 16 can also prevent foreign matter such as dust that impairs the smooth movement operation of 10 from entering between the shutter curtain 1 and the handle member 10.

  Since the cover member 16 is formed with a window hole 16A that allows the above-described recess 58 for the handle of the handle member 10 to face the outside, the window hole 16A from the outside of the cover member 16 is formed on the back surface side of the shutter curtain 1. The handle member 10 can be moved inward in the width direction of the shutter curtain 1 in order to unlock the locking means 15 by the hand inserted into the handle recess 58 and in the window hole 16A. Since the length of the shutter curtain 1 in the width direction is longer than the width of the shutter curtain 1 in the width direction of the shutter curtain 1, the operation of moving the handle member 10 by the handle recess 58 can be performed over a predetermined range.

  Further, since the cover member 16 covers the lock member 31 of the lock means 11 and a part of the slide member 33 connected to the extending member 34, the lock member 31 and the slide member 33 are externally applied. In addition, foreign matter such as dust can be prevented from entering between the lock member 31 and the shutter curtain 1 and between the slide member 33 and the shutter curtain 1, so that the shutter curtain 1 can be locked. Smooth movement of the member 31 and the slide member 33 can be ensured.

  Further, as described above, when the handle member 10 tries to move in the opening / closing movement direction of the shutter curtain 1, which is a direction different from the width direction of the shutter curtain 1, which is the original movement direction, the cover member 16 is Since the upper and lower flange portions 16C serving as the restraining portions for suppressing the play are provided, the cover member 16 restrains the play, and the cover member 16 causes the handle member 10 to move in the width direction of the shutter curtain 1. Therefore, the cover member 16 also serves as a guide member for guiding the handle member 10 in the width direction of the shutter curtain 1, thereby simplifying the structure of the entire apparatus. be able to.

  Further, even when the vertical dimension of the handle member 10 is smaller than the distance between the two upper and lower flange portions 16C of the cover member 16, the handle member 10 is shown in FIG. 15 which is the direction toward the flange portions 16C. Further, since the stopper portions 65 extending in the vertical direction are provided, the difference in the above dimensions can be absorbed by these stopper portions 65.

  Such a stopper portion may be provided on the flange portion 16 </ b> C toward the handle member 10.

  Further, as described above, the cover member 16 is attached to the slat 9A of the shutter curtain 1 via the lock means 11 and the base member 18, and the lock means 11 and the base member 18 attach the cover member 16 to the slat 7A. Since it also serves as a member for attachment, the number of members for attaching and arranging the cover member 16 to the shutter curtain 1 can be reduced, and simplification of the attachment and arrangement structure can be achieved accordingly.

  In FIG. 22, the locking means 11 shown in FIG. 1 is not disposed at the center position in the width direction of the shutter curtain 1 but is disposed at a position closer to one guide rail 4 from the center position in the width direction. The embodiment in the case where the arrangement position of the individual handle members 10 is also changed to the position close to the one guide rail 4 side according to the arrangement position of the locking means 10 is shown. Setting the arrangement positions of the lock means 11 and the handle member 10 in this way is, for example, two sliding sash doors that are opened and closed on the left and right sides for the entrance / exit opening arranged on the back side of the shutter curtain 1. If the lock means 11 is arranged at the center position in the width direction of the shutter curtain 1, the center position of the left and right when the shutter is closed coincides with or substantially coincides with the center position in the width direction of the shutter curtain 1. Even if the door is opened and moved to the left or right, the left and right ends of the sash doors are in the way, and it is difficult to manually rotate the rotation operation member 44 of the lock means 11 described above. Etc.

  Thus, when the arrangement position of the lock means 11 and the handle member 10 is close to one guide rail 4 side, the lock means 11 and the handle member 10 are arranged on both the left and right sides of the lock means 11 shown in FIG. Of the two extending members 34 connected to the member 10 and constituting the unlocking means 90, the extending member 34 disposed on the side opposite to the one guide rail 4 is the shutter. The long dimension member becomes longer in the width direction of the curtain 1, and therefore, the long dimension extension member 34 bends downward due to its own weight. It may be difficult to move the member 34 in the width direction of the shutter curtain 1 as predetermined.

  Therefore, in order to solve such a problem, in this embodiment, as shown in FIG. 23, the long extension member 34 opens the locking means 15 on the slat 9A of the shutter curtain 1. The extending member 34 moves in the up-down direction, which is a direction orthogonal or substantially orthogonal to the moving direction of the shutter curtain 1 and the thickness direction of the shutter curtain 1, that is, the extending member 34 is bent and deformed downward. A regulating member 100 is provided for regulating the above.
