  In this conventional locking device, the locking means is unlocked by moving all the handle members. Therefore, in order to unlock the locking means and move the shutter curtain, For example, when carrying a load in one hand, the device for unlocking the locking means can be unlocked by operating only the other hand, and the device for improving the usability of the shutter device. Desired.

  An object of the present invention is to provide a locking device for an opening / closing device capable of unlocking a locking means even if only one of the plurality of handling members disposed on the opening / closing body is operated to move. There is a place to do.

  The locking device for an opening / closing device according to the present invention includes an opening / closing body, a guide member for guiding opening / closing movement of the opening / closing body, and the opening / closing device for manually opening / closing the opening / closing body along the guide member. A plurality of handle members arranged on the body, locking means for restricting and locking the movement of the opening / closing body with respect to the guide member, and movement of the handle members which are each movably arranged on the opening / closing body In the locking device of the opening and closing device having the unlocking means for unlocking the locking means, the handle member interlocking means for connecting the plurality of handle members and moving the handle members in conjunction with each other It is characterized by having.

  According to this locking device, since the plurality of handle members are connected to each other by the handle member interlocking means, when one of the handle members is moved, the other handle members also move. Thus, the locking means is unlocked, and the locking means can be unlocked by moving the at least one handle member, so that the usability of the opening / closing device provided with this locking device is improved.

  In the locking device of the opening / closing apparatus according to the present invention, the locking for restricting the movement of the opening / closing body relative to the guide member performed by the locking means may be locking for the opening movement, locking for the closing movement, opening movement and closing movement. It may be locked against both movements.

  In this locking device, the number of locking means is arbitrary, for example, it may be one or the same as the number of handle members (one locking means is provided for one handle member). The number may be larger than the number of the handle members. Also, the number of unlocking means is arbitrary, for example, it may be one, and may be the same as the number of handle members (providing one unlock means for one handle member), The number may be the same as the number of locking means (one unlocking means is provided for one locking means), or the number may be greater than the number of handle members or locking means.

  Further, in this locking device, the structures and types of the locking means and the unlocking means are arbitrary. For example, a movable locking member such as a latch member is provided on the opening / 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. The locking member and the locked member are included, and the slide member is connected to the handle member, and the lock member is configured to include the slide member that moves together with the handle member. When the slide member is moving to the locking means side, the slide member prevents the locking member from moving to release the locking away from the locked member, and the slide member is the locking means side. When moving to the opposite side, the slide member does not prevent the locking member from moving away from the locked member to release the locking, so that the locking means can be unlocked. Do It is when. In this example, the movement in which the locking member moves away from the locked member to release the locking may be a rotary motion, a slide motion such as a linear motion, or a motion in which these are combined.

  Another example of the structure and type of the locking means and the unlocking means is that a latch member or the like is provided on the opening / closing body side, and a latch receiving member or the like that is latched on the guide member side. A locking member is provided, and the locking means includes the locking member and the locked member, and the locking member is connected to the handle member via the connecting member, and the unlocking means The locking member is configured to include the connecting member that moves together with the handle member, and when the locking member is moved to the locked member side, the locking means is locked by locking the locking member to the locked member. And the locking member is moved to the side opposite to the locked member side by the movement of the handle member so that the locking by the locking means is unlocked.

  Further, in the locking device of the opening / closing device according to the present invention, the number of the handle members may be two, or three or more. Furthermore, the arrangement positions of these handle members on the opening / closing body are arbitrary. For example, all the handle members may be arranged at the same position or substantially the same position in the opening / closing movement direction of the opening / closing body. The handle member and the remaining handle members may be arranged at different positions in the opening / closing movement direction of the opening / closing body. Further, the position of the opening / closing body in the width direction of each handle member is also arbitrary, and when the number of the handle members is two, these handle members are arranged with respect to the central portion in the width direction of the opening / closing body. You may arrange | position in the distribution position of distance, and may arrange | position in the distribution position etc. of unequal distance.

  Further, when the number of the hook members is two, the above-described hook member interlocking means is used as an example, and the movement of one of the two hook members is moved to the other one of the hook members. Reversing type hand member interlocking means that transmits the information in a reverse direction may be used.

  According to this, since the moving direction of the two handle members for unlocking the locking means by the unlocking means can be reversed, the arrangement positions of the two handle members are shifted in the width direction of the opening / closing body. When the moving direction of one handle member for unlocking the locking means via the unlocking means is, for example, the direction toward the inner side in the width direction of the opening / closing body, the unlocking means The direction of movement of the remaining handle member for unlocking the locking means via the direction opposite to the direction of movement of the one handle member is a direction toward the inside in the width direction of the opening / closing body. Therefore, the operability of these handle members can be improved.

  Thus, the reversible hand member interlocking means for causing the two hand members to reversely move in conjunction with each other may be of any structure and type. One example thereof includes a rack member provided for each handle member, and a pinion member that is disposed between the rack portions of these rack members and that these rack portions mesh with each other on opposite sides. Another example is a rack-and-pinion type, and other examples are slide members provided for each handle member, and both ends are connected to these slide members, and can be freely rotated at the center of these both ends. And a lever member configured to include a lever member. The reversing type handle member interlocking means is not limited to those of these types, and for example, it can be of a link mechanism type or the like.

  Further, the locking device of the opening / closing device according to the present invention may be provided with a locking means for preventing the movement of at least one handle member in order to lock the locking of the opening / closing body by the locking means.

  According to this, since the movement of at least one handle member is prevented by the lock means, and thereby the movement of all the handle members connected to each other by the handle member interlocking means is prevented, the unlocking is performed. The locking means cannot be unlocked via the means, and the locking of the opening / closing body by the locking means can be maintained. In addition, after releasing the blocking of the movement of at least one handle member by the locking means, if the at least one handle member is moved, the other handle member is moved in conjunction with the interlocking means. The locking means can be unlocked via the unlocking means.

  As described above, when the locking device for blocking the movement of at least one handle member is provided in the locking device of the switchgear according to the present invention, the handle member interlocking means is provided as a means penetratingly disposed inside the lock means. Also good.

  According to this, even if the lock means is arranged at a position between a plurality of handle members provided on the opening and closing body, the handle member interlocking means is disposed penetrating inside the lock means. There is no obstacle in arranging the handle member interlocking means, and the lock means and the handle member interlocking means can be rationally arranged on the opening / closing body.

  In this manner, the penetrating member interlocking means can be disposed through the lock means in both cases where the number of the clasp members is two or three or more. In the case where the number of the handle members is two, in order to dispose the handle member interlocking means through the lock means, as an example, the handle member interlocking means includes a rack member provided for each handle member, and these At least a part of each of the rack parts, and the rack parts are arranged between the rack parts of the rack members, and the rack parts are engaged with each other on the opposite sides. Can be inserted into the lock means, and the pinion member disposed between the rack portions can be accommodated in the lock means.

  In this case, the pinion member is a first pinion member, and the lock means is a second pinion member that rotates at least one of a key operation and a manual operation, and each of the second pinion members is opposite to the second pinion member. And two lock members that move forward to positions where the rack members are prevented from moving by the respective handle members by rotation of the second pinion member. In this case, the first pinion member may be rotatably disposed on the rotation center member of the second pinion member.

  According to this, the first pinion member, which is a member constituting the handle member interlocking means, is a member constituting the locking means, and the member serving as the rotation center of the second pinion member of the locking means. Can be rotatably arranged inside the lock means, whereby the structure of the handle member interlocking means can be simplified and the number of necessary members can be reduced.

  Furthermore, in the locking device of the opening / closing apparatus according to the present invention, each handle member may be provided only on one surface of the opening / closing body, or may be provided on both surfaces of the opening / closing body.

  One example of realizing the latter is to dispose up to the middle of the thickness of each handle member through the opening / closing body in the thickness direction of the opening / closing body. According to this, it becomes the same as that the handle member is arranged on both surfaces of the opening / closing body by one handle member, and the number of handle members to be prepared can be reduced.

  In addition, in the case where up to the middle of the thickness of each handle member is disposed so as to penetrate through the opening / closing body in the thickness direction of the opening / closing body, the both sides of the handle member in the thickness direction of the opening / closing body are provided. A recess for handling may be formed.

  According to this, by these recesses for the handle, the operation of moving the handle member for unlocking the locking means from both sides of the opening / closing body via the unlocking means, and the opening / closing body with respect to the guide member after unlocking It is possible to perform manual operation for movement, and operability related to the handle member is improved.

  Further, in the case where up to the middle part of the thickness of each handle member is disposed through the opening / closing body in the thickness direction of the opening / closing body, the thickness of the handle member is arranged in the opening / closing body for the penetration arrangement. An opening for inserting the middle part of the opening / closing body from one side to the other in the thickness direction of the opening / closing body is formed, and the edge portion of the opening at the time of the insertion is formed on the portion of the handle member inserted into the opening. The elastic part may be formed by elastic compression deformation and elastic deformation after insertion.

  According to this, when the operation of inserting the opening member up to the middle of the thickness of the handle member from one side to the other in the thickness direction of the opening / closing body for the penetrating arrangement is performed, The elastic part elastically deformed by deformation at the edge part is elastically deformed and deformed after this insertion work, so that the handle member can be naturally locked to the opening part by the elastic part. The elastic compression deformation and the elastic restoring deformation can be performed easily and in a short time.

  In addition, each handle member has two portions shifted in the width direction of the opening / closing body, and one of these portions is inserted into the opening so that the handle member is shifted in the width direction of the opening / closing body. When the other part reaches the position corresponding to the opening, the elastic part is provided in the other part, and the elastic part is orthogonal to the width direction of the opening / closing body or It is good also as a taper shape from which the dimension of the opening / closing movement direction substantially orthogonally becomes large gradually on the opposite side to the said shifting movement direction.

  According to this, when the handle member is shifted and moved in the width direction of the opening / closing body so that the other portion reaches a position corresponding to the opening, the elastic portion is orthogonal to the width direction of the opening / closing body. Since the taper shape in which the dimension in the opening / closing movement direction substantially orthogonal to the shift movement direction gradually increases is formed on the side opposite to the shifting movement direction, the elastic shape of the elastic portion at the edge of the opening is further reduced by the taper shape. It can be done reliably.

  Further, in the locking device of the opening / closing apparatus according to the present invention, when the unlocking means has a connecting member connected to the handle member, the connecting member is connected to the opening / closing body between the connecting member and the opening / closing body. An intermediate member for preventing contact may be arranged.

  According to this, since the intermediate member can prevent the connecting member from coming into contact with the opening / closing body due to the swinging of the connecting member during the opening / closing movement of the opening / closing body, etc., the difference that occurs when the connecting member contacts the opening / closing body. Generation of sound or the like can be prevented.

  Thus, when arrange | positioning the intermediate member for preventing that a connection member contacts an opening / closing body between a connection member and an opening / closing body, as an example, you may attach this intermediate member to a connection member.

  According to this, even if the connecting member is moved by the movement operation of the handle member, the intermediate member moves integrally with the connecting member. Therefore, unlike the case where the intermediate member is arranged on the opening / closing body, the intermediate member is connected to the connecting member. It is possible to eliminate the deviation from the moving range.

  Note that attaching the intermediate member to the connecting member may be mechanically or structurally fastened to the connecting member, may be attached using an adhesive or a pressure sensitive adhesive, and may be adhesive such as coating. Alternatively, the intermediate member may be scientifically fixed to the connecting member, or a combination of at least two of them may be used.

  Furthermore, in the locking device of the opening / closing device according to the present invention, when the unlocking means has a connecting member connected to the handle member, the connecting member causes the opening / closing body to unlock the locking means as described above. It is preferable to provide a restricting member for restricting the movement of the connecting member in a direction orthogonal or substantially orthogonal to the direction in which the connecting member moves and the thickness direction of the opening / closing body.

  According to this, even if the connecting member has a long dimension, the connecting member is in a direction orthogonal or substantially orthogonal to the direction in which the connecting member moves to unlock the locking means and the thickness direction of the opening / closing body. Is deformed by the restricting member, so that the connecting member can be moved in a predetermined manner to unlock the locking means.

  For this reason, the shape, type, and the like of the restriction member provided on the opening / closing body are arbitrary, and an example thereof is that the restriction member is a band member disposed outside the connecting member.

  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. When the opening and closing device to which the locking device according to the present invention is applied is a shutter device in which the opening and closing body is a shutter curtain, the shutter device is an opening that opens and closes openings such as doorways and windows with the shutter curtain. A shutter device for a section, a shutter device for a garage, a shutter device for a storage, or a shutter device for a vehicle mounted on a loading platform of a vehicle such as a truck, or a shutter for disaster prevention that forms a disaster prevention section with a shutter curtain It may be a 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 forming member formed by a panel or the like. The shutter device may be folded and stored while being stored while being separated from each other.

  When the locking device according to the present invention is applied to a shutter device that winds and stores a shutter curtain with 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-shaped 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 assisted shutter device that is used as an auxiliary 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, since the locking means can be unlocked even if only one of the plurality of handle members arranged on the opening / closing body is moved, the usability of the switchgear is good. The effect that it can be made.

  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.

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 opposite small projection 46 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 in the state of FIGS. 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 locking means 11, and these rack portions 30A mesh with the pinion members 48 arranged between these rack portions 30A on the upper and lower sides opposite to each other. is doing. 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 in 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 first bar member 32, and the other rack member. Since 30 is connected to the other handle member 10 by the first bar member 32, when one of the pair of handle members 10 is moved with respect to the shutter curtain 1, this movement is caused by a pair of racks. It is transmitted to the other handle member 10 through the member 30 and the pinion member 48, and the two handle members 10 can be moved by operating the one handle member 10.

  Therefore, the first bar member 32, the pair of rack members 30, and the pinion member 48 connect the two handle members 10 to each other, and the rack and can move these handle members 10 in conjunction with each other. A pinion-type 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 has reached the forward movement position shown in FIGS. 8 and 12 by the operation, the stopper portions 31B are bent portions 30B to which the first bar members 32 of the rack member 30 are coupled (see FIG. 12), the respective handle members 10 are arranged inwardly in the width direction of the shutter curtain 1 in order to unlock the locking means 15 described in FIGS. 2 and 21, as will be described later. The bent portion 30B of the rack member 30 which is about to move integrally with the handle member 10 via the first bar member 32 is moved to the stop of the lock member 31. Since the pinion member 42 does not rotate by the slide driving force from the lock member 31 and the lock member 31 remains stopped at the forward position, as described above, The movement of the rack member 30 by the handle member 10 is blocked by the lock member 31, and each handle member 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 the configuration of the locking means 15. The shutter curtain 1 is a part on the outer side in the width direction of the shutter curtain 1, and the second part is a part 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 movable in the width direction of the shutter curtain 1 to the slat 9A by the distance L. Is arranged.

  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 first and second bar members 32, 34 to the handle member 10, the shutter curtain 1 is opened to the middle part of the thickness of the handle member 10 having the shape and size as described above by the opening 56. The operation of penetrating and arranging in 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 first and second bar members 32 and 34 to the formed connecting portions 59 and 60 is performed. In this embodiment, the connecting operation is performed by inserting and engaging a bent part of the metal bar members 32 and 34 into holes formed in the connecting portions 59 and 60 in the present embodiment. Is to be done by. Further, after the operation of connecting the first and second bar members 32 and 34 to the connecting portions 59 and 60 is performed, the cover member 16 shown in FIG. 2 covering these first and second bar members and the like is locked. The work of attaching to the means 11 etc. is performed.

  15 is a cross-sectional view taken along line S15-S15 in FIG. 4 when the cover member 16 is attached. 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 stopper portion 65 abuts against the inner surface of the flange portion 16C, thereby preventing the handle member 10 from swinging in the vertical direction. The moving operation of the handle member 10 performed manually can be performed while feeling a good feeling.

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

  Due to the buffer member 66, when the shutter curtain 1 is opened and closed by winding and unwinding of the winding shaft 6 shown in FIG. The second bar 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 second bar member 34 comes into contact with the slats 9A can also be prevented.

  Further, since the buffer member 66 is attached to the second bar member 34, even if the second bar member 34 moves with respect to the slat 9 </ b> A by the movement operation of the handle member 10, the buffer member 66 remains in the second bar member 34. Unlike the case where the buffer member 66 is attached to the slat 9A, the buffer member 66 does not deviate from the movement range of the second bar member 34.

  Furthermore, in this embodiment, since the buffer member 66 bites into the lip portion 34A of the second bar member 34, the buffer member 66 is firmly attached to the second bar member 34 together with the adhesive bonding. Even if the second bar member 34 is moved by the movement operation of the handle member 10, it does not come off from the second bar member.

  An intermediate member similar to the buffer member 66 may also be attached to the first 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 outer end of the second bar member 34 described in FIG. 4 in the width direction of the shutter curtain 1, and this second bar member. Since the end of the shutter curtain 1 on the inner side in the width direction of the shutter 34 is connected to the handle member 10, the movement of the handle member 10 in the width direction of the shutter curtain 1 via the second bar member 34 is a slide member 33. 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 locked member 14, the locking member 13 resists the coil spring 71 so that the locking portion 13A is in the state of the two-dot chain line 13A ′. As a result, 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. For this reason, 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 also moves inward in the width direction of the shutter curtain 1 via the second bar 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 rotates downward about the pin 70 until the state of the two-dot chain line 13A ″ 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. It will be.

  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 second bar 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.

  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 handle member 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 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 embodiment described above, the two handle members 10 provided on the shutter curtain 1 are connected by the rack and pinion type handle member interlocking means 50, and therefore only one of these handle members 10 is provided. Even when the shutter curtain 1 is moved inward in the width direction, the other handle member 10 can be moved inwardly in the width direction of the shutter curtain 1 by the handle member interlocking means 50, thereby opening each locking means 15. The shutter curtain 1 can be opened and moved, and the usability of the shutter device is improved.

  The rack-and-pinion-type handle member interlocking means 50 is a reversible interlocking means that can transmit the movement of one handle member 10 to the other handle member 10 by reversing the moving direction. The movement operation direction of each handle member 10 for unlocking is the inside of the shutter curtain 1 in the width direction. For this reason, the usability of the shutter device can be improved.

  Further, since each of the handle members 10 is provided with the above-described recesses 57 and 58 for the handle on both sides of the shutter curtain 1, the locking means 15 is unlocked via the unlocking means 90. The manual operation for moving the shutter curtain 1 and the manual operation for moving the shutter curtain 1 can be performed on both sides of the shutter curtain 1, and the usability of the shutter device is also good in this respect.

  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.
