[Problems to be solved by the invention]
In a shutter device provided with a locking device, the locking device must be unlocked in order to open and move the shutter curtain.However, conventionally, a member that is manually operated to perform this unlocking is separate from the handhold portion. It was provided on the shutter curtain. For this reason, the structure of the shutter curtain becomes more complicated, and the number of members that must be prepared increases.
[0006]
SUMMARY OF THE INVENTION An object of the present invention is to provide an unlocking device in an opening / closing device that can simplify the entire structure of the opening / closing member by making a locking portion and a handle portion provided on the opening / closing member such as a shutter curtain have a reasonable relationship. To provide
[0007]
[Means for Solving the Problems]
The unlocking device in the opening / closing device according to the present invention includes an opening / closing body that is guided by a guide member and that opens and closes, a handle provided on the opening / closing body, and a hand that is hooked to move the opening / closing body; A locking device that locks the opening / closing body so as to disable movement of the body, wherein the grip portion includes a gripping member movably provided with respect to the opening / closing body. And the locking member is connected to an unlocking mechanism for unlocking the locking device, and the locking device is unlocked by a moving operation of the locking member. is there.
[0008]
According to this unlocking device, the grip portion is formed to have a grip member movably provided with respect to the opening / closing body, and the grip member is connected to an unlocking mechanism for unlocking the locking device. Since the locking device is unlocked by moving the gripping member, the gripping member on which a hand is hooked to move the opening / closing body is also a member for unlocking the locking device. Therefore, the members are shared, and the entire structure of the opening / closing body can be simplified accordingly.
[0009]
In this unlocking device, the direction of movement of the handle member relative to the opening / closing body may be any direction, for example, the width direction of the opening / closing body, the opening / closing movement direction of the opening / closing body, or the thickness direction of the opening / closing body. May be a direction in which at least two of the directions are combined. In addition, the movement of the handle member may be a linear movement, a rotational movement, a curved movement, or a bending movement, or a combination of these movements.
[0010]
Further, the relationship between the moving direction of the handle member and the unlocking mode of the locking device by the unlocking mechanism is arbitrary.
[0011]
For example, when the handle member is movable in the width direction of the opening / closing body, the locking device is provided with a locking member disposed on the opening / closing body near the width direction end of the opening / closing body, An end portion in the width direction of the body is disposed on a guide member that is slidably inserted in the opening and closing movement direction of the opening and closing body, and is formed including a locked member that is locked by locking a locking member. It is assumed that the locking member is released from being locked with the locked member by moving inward in the width direction of the opening and closing body, and a hand-held member that is movable in the width direction of the opening and closing body, The opening and closing body is connected via a connecting member that is movable in the width direction, and the connecting member is a member that forms at least a part of the unlocking mechanism.
[0012]
According to this, all of the hand-holding member, the locking member, and the connecting member can be members that move in the width direction of the opening / closing body, so that the overall structure of the opening / closing body can be simplified also in this respect.
[0013]
The movement of the locking member inward in the width direction of the opening / closing body may be a linear movement, or a rotation having a component in a direction parallel to the surface of the opening / closing body or in a thickness direction of the opening / closing body. Movement or a combination of these movements.
[0014]
Another example is that when the hand-holding member is movable in the opening and closing movement direction of the opening and closing body, the locking device is disposed on the opening and closing body near the widthwise end of the opening and closing body. A member and a locked member in which the widthwise end of the opening / closing body is disposed on a guide member that is slidably inserted in the opening / closing movement direction of the opening / closing body, and the locking member locks the locked member. And a locking member that is unlocked from the locked member by moving inward in the width direction of the opening and closing body, and is movable in the opening and closing movement direction of the opening and closing body. The handle member is connected via a moving direction changing means for changing the moving direction between the opening and closing movement direction of the opening and closing body and the width direction of the opening and closing body, and the moving direction changing means is connected to at least a part of the unlocking mechanism. It is a means that has been formed.
[0015]
According to this, since the moving direction of the handle member is the same as the opening / closing movement direction of the opening / closing body, the hand member is moved in the opening movement direction of the opening / closing body in order to hang the hand member and open / close the opening / closing body. The opening and closing operation of the opening / closing body by the hand-holding member is configured such that the locking member moves inward in the width direction of the opening / closing body that is released from the engagement with the locked member via the moving direction conversion means when the operation is performed. And the unlocking operation of the locking device can be performed as the same operation, and operability can be obtained.
[0016]
The moving direction changing means in this example may be of any structure and type, for example, may be a rack and a pinion, may be a tapered cam, may be a link, may be a lever, may be a rotating member. Or the like.
[0017]
Also in this example, the movement of the locking member to the inside in the width direction of the opening / closing body may be a linear movement, or a direction parallel or substantially parallel to the surface of the opening / closing body, or a thickness direction of the opening / closing body. The movement may be a rotational movement having a component, or a combined movement thereof.
[0018]
In the present invention, the handle portion may be formed by a handle member and another member, or may be formed only by the handle member.
[0019]
In the present invention, the handle member may be one that can be moved from only one of the front side and the back side of the opening / closing body, but is more preferably one that can be moved from both the front and back sides. When the handle member can be moved from both front and back sides of the opening and closing body, the person who tries to move the opening and closing body by unlocking the lock is on both the front and back sides of the opening and closing body. Can be moved.
[0020]
In order to be able to move the hand-held member from both the front and back sides of the opening / closing body in this way, the hand-held member is disposed on the opening / closing body at a position corresponding to a hole formed through the front and back of the opening / closing body. . The hole may be for allowing a hand-held member arranged on one of the front side and the back side of the opening / closing body to be touched by a hand inserted from the other, or that the hand-held member is The opening / closing member may be inserted, and the holding member may be exposed on both front and back sides of the opening / closing body.Further, a part of the holding member arranged on one of the front side and the back side of the opening / closing body may be inserted. And a part thereof may be projected to the other.
[0021]
Further, it is preferable that the opening / closing body is provided with a lock device capable of selecting whether to allow or prevent the movement of the hand-holding member in the direction of unlocking the locking device. According to this, the unlocking operation of the locking device by the hand-holding member can be prevented by the locking device that is operated as needed, thereby prohibiting the movement of the opening / closing body.
[0022]
As described above, when the opening / closing body is provided with the lock device capable of selecting whether to allow or prevent the movement of the handhold member in the direction of unlocking the locking device, as an example, the lock device is moved forward and backward by operating the operation member. A lock member is provided, and the lock member, which has advanced to the side of the handle member, prevents movement of the handle member in the direction of unlocking the locking device.
[0023]

A pair of locking members, which are released from being locked to the locked member by the movement of the opening / closing member, are connected via a movement direction reversing mechanism for reversing the movement direction between the inside in the width direction and the outside in the width direction of the opening / closing body. Then, two hands are moved through the moving direction reversing mechanism. It is to link only members together.
[0029]
According to this, two locking devices including a locking member and a locked member are provided on both sides in the width direction of the opening / closing body, and two locking members for unlocking these locking devices are provided. Even if the moving directions of the two hand members are opposite to each other, when one of the hand members is moved, the other hand member is moved in the opposite direction by the moving direction reversing mechanism. Even if the members are moved, each locking device can be unlocked.
[0030]
The moving direction reversing mechanism may be of any structure and type, for example, a rack and pinion, a tapered cam, a link, a lever, a rotating member, etc. It may be something.
[0031]
Such a moving direction reversing mechanism can be applied to an opening / closing body provided with the locking device, and can also be applied to an opening / closing body not provided with the locking device.
[0032]
In addition, even when a moving direction reversing mechanism is provided in which the other hand member moves in the opposite direction when the one hand member is moved, the locking member is moved inward in the width direction of the opening / closing body. May be a linear movement, or a rotational movement having a component in a direction parallel or substantially parallel to the surface of the opening / closing body or in the thickness direction of the opening / closing body, and these are combined. It may be moving.
[0033]
Furthermore, the above-described handle member, the locking member, the unlocking mechanism, and the lock device when the lock device is provided on the open / close body are arranged at the same or substantially the same position in the opening / closing movement direction of the open / close body.

[0053]
The locking member 21 slidably held in the width direction of the shutter curtain 1 by the guide member 23 on the slat 9A is connected to the hand-holding member 10 via the connecting member 24, and is connected to these locking members 21. The member 24 and the handle member 10 are constantly elastically urged outward in the width direction of the shutter curtain 1 by a spring 25.
[0054]
Further, the lock device 11 is provided with a lock member 26 which advances and retreats outward in the width direction of the shutter curtain 1. The lock member 26 is bent outward from the main body 26 </ b> A in the width direction of the shutter curtain 1. A protruding portion 26B is formed, and the protruding portion 26B overlaps the first extension portion 10A of the handhold member 10 extending inward in the width direction of the shutter curtain 1 in the thickness direction of the shutter curtain 1. Further, as shown in FIG. 4, the lock member 26 in a normal state is retracted toward the main body 11A of the lock device 11.
[0055]
FIG. 5 is an enlarged view of a main part of FIG. 4 showing a relationship between the lock member 26 and the handhold member 10 in the normal state. 6 is a sectional view taken along line S6-S6 in FIG. 5, FIG. 7 is a sectional view taken along line S7-S7 in FIG. 5, and FIG. 8 is a sectional view taken along line S8-S8 in FIG.
[0056]
As shown in these figures, the protrusion 26B of the lock member 26 is provided with upper and lower flanges 26C and 26D, and the lower flange 26D is connected to the lower surface 10B of the first extension 10A. Along with the lower surface portion 10B, it is inserted between the guide portion 27 formed long in the first extension portion 10A in the width direction of the shutter curtain 1, which is the longitudinal direction of the handle member 10. Further, a stopper 28 is formed on the first extension 10A at a position separated by a predetermined distance from the tip of the extension 10A, and when the lock member 26 advances to the first extension 10A side. Alternatively, when the first extension 10A moves toward the lock member 26, the upper flange 26C and the stopper 28 come into contact with each other.
[0057]
Therefore, the above-described locking member 21, connecting member 24, and handholding member 10 can move inward in the width direction of the shutter curtain 1 until the stopper portion 28 contacts the upper flange portion 26C.
[0058]
As shown in FIG. 5, the second extension 10 </ b> C of the handle member 10 extending outward in the width direction of the shutter curtain 1 is overlapped with the end of the connecting member 24, and is a cross-section taken along line S <b> 9-S <b> 9 of FIG. 5. As shown in FIG. 9, by bending the protruding piece 24 </ b> A of the connecting member 24 and inserting and engaging with the hole 10 </ b> D of the second extension 10 </ b> C, the handle member 10 and the connecting member 24 are connected. I have.
[0059]
As can be understood from the above description, while the shutter curtain 1 reaching the fully open position is closed and moved to the fully closed position, the inclined surface 21A of the locking member 21 shown in FIG. When the inclined surface 22A comes into contact with the inclined surface 21A, the taper action of the inclined surfaces 21A, 22A causes the locking member 21, the connecting member 24, and the handholding member 10 to move the stopper 28 of the handholding member 10 to the upper flange Prior to contact with 26C, the shutter curtain 1 once retreats inward in the width direction of the shutter curtain 1 against the spring 25 shown in FIG. 4, and then advances forward in the width direction of the shutter curtain 1 by the spring 25, When the shutter curtain 1 reaches the fully closed position, the upper surface of the locking member 21 is locked to the locking surface 22B of the locked member 22, as shown in FIG. .
[0060]
As a result, the locking device 20 is automatically locked, and the shutter curtain 1 cannot be opened and moved when fully closed.
[0061]
Further, when the locking member 20 is locked in this way, if the hand-holding member 10 is moved inward in the width direction of the shutter curtain 1, this movement is transmitted to the locking member 21 via the connecting member 24, Since the locking of the locking member 21 to the locked member 22 is released, the shutter curtain 1 can be opened and moved as it is by applying a lifting force to the handle member 10.
[0062]
That is, the connecting member 24 is a member that forms the unlocking mechanism 30 according to the present embodiment for unlocking the shutter curtain 1 by the locking device 20.
[0063]
As described above, according to the present embodiment, the handle member 10, which is originally a handle portion provided on the shutter curtain 1 for opening and moving the shutter curtain 1 by hand, is provided by the locking device 20. Since the lock member 10 is connected to the unlocking mechanism 30 for unlocking the lock, the handle member 10 also serves as a member for manually unlocking the lock of the lock device 20.
[0064]
Therefore, according to the present embodiment, the number of members that must be provided in the shutter curtain 1 can be reduced accordingly, and the overall structure of the shutter curtain 1 can be simplified.
[0065]
In addition, the handle member 10 is disposed at a position corresponding to the hole 12 formed through the slat 9A, and the handle member 10 can be moved from both the front and back sides of the shutter curtain 1, so that the locking device 20 is unlocked by the handle member 10. The operation and the opening movement operation of the shutter curtain 1 can be performed from both the front and back sides of the shutter curtain 1 as necessary.
[0066]
Furthermore, according to this embodiment, since the handle member 10, the locking member 21, and the connecting member 24 are members that move in the width direction of the shutter curtain 1, the handle member 10 and the unlocking mechanism are also provided in this regard. The entire structure of the shutter curtain 1 including the shutter curtain 30 can be simplified.
[0067]
FIG. 10 shows a case where a pair of lock members 26 provided on the left and right sides of the lock device 11 are retracted toward the main body 11A of the lock device 11, similarly to the handle member 10, the connecting member 24, and the lock member 21. Shows a case where these lock members 26 have advanced from the main body 11A side to the handhold member 10 side. FIG. 12 shows the lock device 11 as viewed from the front side of the shutter curtain 1, and FIG. 13 shows a cross-sectional view of the lock device 11.
[0068]
A rotor 41 shown in FIG. 13 is fitted around the outer periphery of the rotary plug 40 having a key hole 40A into which the plate key shown in FIG. 12 is inserted. The first tumbler (not shown) that has stopped rotating retracts, and the second tumbler (not shown) that connects the rotating plug 40 and the rotor 41 projects. Therefore, the rotary plug 40 and the rotor 41 can be rotated by the plate key inserted into the keyhole 40A. Since the rotor 41 is formed with the teeth 43 shown in FIG. 13 that mesh with the rack teeth 42 of the pair of lock members 26 shown in FIG. 12, the rotor 41 is rotated 180 degrees in one direction by rotating the plate key.
