DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called panel shutter driving device for opening and closing a doorway of a parking lot by using several panels.

[0002]

2. Description of the Related Art Generally, as shown in FIG. 24, a pair of left and right guide rails (hereinafter, referred to as first guide rails) 93 having a panel 91 standing at an entrance 92 and a first shutter are generally used as the panel shutter. It moves between a guide rail (hereinafter, referred to as a second guide rail) 94 disposed substantially horizontally behind and above the guide rail 93. Guide roller 9
9 is attached to both upper and lower sides (only one side is shown) of the panel 91, and rolls on the first guide rail 93 and the second guide rail 94. As a result, the panel 91 can move smoothly along the guide rails 93 and 94. A chain (or a wire or the like) 95 is connected to the shaft of each guide roller 99. This chain 95 is connected to driving devices 96 and 97.
The panel 91 moves along the guide rails 93 and 94 by winding or unwinding, and the doorway 92 is opened and closed.

When the doorway 92 is closed, the panel 91 is accommodated between the first guide rails 93. When the doorway 92 is open, the panel 91 is held between the second guide rails 94. Will be accommodated. Individual chains 95 are connected to the upper and lower portions of the panel 91. Then, both chains 95 are wound or fed out by the respective driving devices 96 and 97, and the panel 91 moves along the guide rails 93 and 94. As described above, conventionally, at least two driving devices 96 and 97 are used to move the panel 91.

In the case where only one driving device 96, 97 is provided (when the chain 95 is connected only to the upper portion of the panel 91 or only to the lower portion of the panel 91), the first device is used.
The panel 91 cannot be moved unless a gentle gradient (or a smooth curve) as shown by a two-dot chain line is provided at the boundary between the guide rail 93 and the second guide rail 94. In this case, a useless space is formed above the first guide rail 93. For these reasons, two driving devices are required. That is, the panel 91 is pulled up from above by one driving device 96,
The panel 91 is pushed up from below by the other driving device 97. Thus, the boundary between the first guide rail 93 and the second guide rail 94 can be made substantially perpendicular, and no useless space is formed.

The driving devices 96 and 97 move the panel 91 using separate motors (not shown). When the panel 91 moves, the controller 98 moves.
, The rotation speed of each motor is adjusted. For example,
When the controller 92 opens the entrance 92, the upper part of the panel 91 escapes from the first guide rail 93, and the second
After reaching the guide rail 94, the rotation speeds of both motors are adjusted to make the amount of movement per hour between the upper part and the lower part of the panel 91 different. Thus, the panel 91 is smoothly guided by the guide rails 93 and 94.

[0006]

However, the above-described panel driving device has the following problems. (1) Since the rotation speeds of the motors of the respective driving devices 96 and 97 are controlled by the controller 98, a dedicated program is required and the cost is high. Also, the controller 98
Is performed based on the position of the panel 91 in controlling the number of rotations of the motor, so that a sensor or the like for detecting the position of the panel 91 is required, and the configuration of the apparatus becomes complicated.

(2) When the controller 98 fails or the program malfunctions, the panel 91 cannot be moved normally. (3) Since at least two drive devices (motors) 96 and 97 are required, the number of parts and the assembling work are increased, and the cost is high.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and a first object of the present invention is to allow a panel to move smoothly without changing the number of rotations of a motor based on the position of the panel. It is to provide a simple panel driving device.

A second object is to provide a panel driving device capable of moving a panel smoothly with one motor.

[0018]

According to the panel drive device of the first aspect, for example, when the panel moves from the first guide rail to the second guide rail, the panel is driven from the drive source via the differential body and each transmission member. Power is transmitted to the first support and the second support, respectively. As a result, the panel moves from the first guide rail toward the second guide rail. Then, when one of the supports (for example, the second support) reaches the second guide rail, the first guide is moved by the differential.
The amount of movement per unit time between the support and the second support is adjusted. This eliminates the need to provide a plurality of motors or the like serving as drive sources, and eliminates the need for a controller that controls the number of rotations of the motors and the like.

According to the panel driving device of the second aspect, since the driving source is a motor, the panel can be moved quickly.

It is possible to prevent a person passing through the doorway from tripping.

According to the panel driving device of the present invention, each support is rotated in accordance with the inclination angle of the panel which changes with the movement of the panel. Thereby, the driving force transmitted from the driving source via the transmission member is efficiently transmitted to the support.

According to the panel driving device of the ninth aspect, when the panel is raised, the auxiliary panel is urged by the elastic member and protrudes from the panel. When the panel descends, it comes into contact with the ground from the auxiliary panel. At this time, the impact when the auxiliary panel comes into contact with the ground is reduced by the elastic force of the elastic member. Further, even when the panel cannot be completely lowered due to an abnormality in the drive source or the like, the gap between the ground and the panel is closed by the auxiliary panel because the auxiliary panel projects from the lower end of the panel.

According to the panel driving device of the tenth aspect, since the first support is provided near the second support, even when the panel is completely opened, the lower part of the panel remains in the first position. Projecting from one guide rail. This protruding part can be used as a room.

The differential body 42 includes a differential pinion 43 including a pair of bevel gears, a first side gear 44, a second side gear 45, and the like. Side shaft 46
Is fixed to the pinion shaft 47, rotates together with the pinion shaft 47. The side shaft 46 is rotatably inserted into both side gears 44 and 45. The pinion shaft 47 is rotatably inserted into the differential pinion 43. Each of the side gears 44 and 45 meshes with each of the differential pinions 43.

The driving force input sprocket 48 is supported at one end of the side shaft 46. The drive chain 49 connects the drive sprocket 40 and the drive force input sprocket 48. First output sprocket 50
Is connected to the first side gear 44 and the second output sprocket 51 is connected to the second side gear 45 so as to be integrally rotatable. Further, the first output-side sprocket 50 to the second output sprockets 51, the side shaft 46 is inserted rotatably.

The first counter shaft 52 is connected to the left and right first counter shafts.
And the left and right first driving sprockets 26 are synchronously rotated. The first input sprocket 53 is supported by the first counter shaft 52 so as to be integrally rotatable. The first output chain 54 connects the first output sprocket 50 and the first input sprocket 53. Therefore, the first output sprocket 50 and the first input sprocket 53 rotate synchronously via the first output chain 54. Then, the rotational force is transmitted to the first drive side sprocket 26 via the first counter shaft 52, and serves as power for rotating the first panel moving chain 28.

The first output sprocket 50 is connected to the first side gear 44 so as to be integrally rotatable. The second output side sprocket 51 is connected to the second side gear 45 so as to be integrally rotatable. A side shaft 46 is rotatably inserted through the second output sprocket 51.

Of the drive-side sprocket 26 protrudes outward from the mounting position. The second input sprocket 57 is supported by a second counter shaft 56. The second output chain 66 connects the second output sprocket 51 and the second input sprocket 57.

The second drive sprocket 58 is supported at both ends of the second counter shaft 56.
Both second drive sprockets 58 rotate synchronously via a second counter shaft 56. The relay shaft 59 is supported so as to penetrate the side wall 30 of the chain housing 25. The relay sprockets 60 and 61 are connected to the relay shaft 5
9 are supported at both ends. Relay chain 65
Connects the second drive side sprocket 58 and the outer intermediate sprocket 60 . The driven sprocket 64 is rotatably supported at the rear of the second guide rail 3.

A second panel moving chain 62 as a second transmission member connects the inner relay sprocket 61 and the driven sprocket 64. The chain connecting body 24 on the second support plate 22 side is fixedly attached to a second panel moving chain 62.

Next, the operation of the panel shutter configured as described above will be described. First, as shown in FIG. 1 and FIG.
Is released, the motor 41 is driven. Motor 4
When the motor 1 is driven, the rotational force of the motor 41 is transmitted from the drive sprocket 40 to the drive input sprocket 48 via the drive chain 49. Thereby, the side shaft 46 of the differential body 42 is rotated. With the rotation of the side gear 46, the pinion shaft 47 is rotated. When the pinion shaft 47 is rotated, the rotational force is transmitted to the differential pinion 43. When the differential pinion 43 is rotated, the rotational force is transmitted to the first side gear 44 and the second side gear 45.

The rotational force of the first side gear 44 is transmitted to the first input sprocket 53 via the first output sprocket 50 and the first output chain 54. The rotation of the first input sprocket 53 causes the first sprocket 53 to rotate.
Is rotated, and both first drive side sprockets 26 are rotated. The rotation of the first drive sprocket 26 causes the first panel moving chain 28 to rotate between the first drive sprocket 26 and the first driven sprocket 27 counterclockwise in FIG. Is done. As a result, the chain connector 20 attached and fixed to the first panel moving chain 28 is moved upward, and a force is applied to the first panel 11 to push it up from below.

On the other hand, the rotational force of the second side gear 45 is
The power is transmitted to the second input sprocket 57 via the second output sprocket 51 and the second output chain 66. When the second input side sprocket 57 is rotated, the second counter shaft 56 is rotated, and both the second drive side sprockets 58 are rotated. The rotational force of the second driving sprocket 58 is applied to the outer intermediate sprocket 60.
, And transmitted to the inner relay sprocket 61 via the relay shaft 59. As a result, the inner relay sprocket 61 is rotated counterclockwise. Along with this, the second panel moving chain 62 is rotated clockwise in FIG. 2, and the chain connector 24 attached and fixed to the second panel moving chain 62 is moved rearward. As a result, the second panel 11 is given a pulling-up force from above.

The panel 1 is moved by the cooperation of the pushing force applied to the first panel 11 and the lifting force applied to the second panel 12. When the position of the panel 1 is in FIGS. 1 and 2, that is, when the first guide roller 17 and the second guide roller 21 are both on the first guide rail 1, the first side gear 44
Is slightly higher than the rotation speed of the second side gear 45.

As shown in FIG. 8, the second guide roller 2
When 1 moves from the first guide rail 1 to the second guide rail 3, the rotation speed of the first panel movement chain 28 becomes smaller than the rotation speed of the second panel movement chain 62 by the action of the differential body 42. Will also be lower. When the panel 10 is further moved to the position shown in FIG. 9, the difference in the number of rotations between the first guide roller 17 and the second guide roller 21 further increases. That is, the first panel 11 rotates via the hinge 13, and as the angle between the panels 11 and 12 decreases, the rotational speed difference between the first side gear 44 and the second side gear 45 increases. Thereby, the movement of the panel 10 is performed smoothly.

As shown in FIG. 10, when both the first guide roller 17 and the second guide roller 21 travel on the second guide rail 3, that is, the first panel 11 and the second panel 12 is 180 °, the rotation speed of the second side gear 45 becomes substantially zero.

When the panel 10 reaches a predetermined position of the second guide rail 3 (the state in which the entrance 2 is fully open), the fact is detected by a limit switch (not shown) and the motor 4
1 is stopped. The operation of the motor 41 can be stopped even during the movement of the panel 10 by operating a switch (not shown).

When closing the entrance 2, the motor 41 is rotated in the reverse direction. Thereby, the panel 10 moves from the second guide rail 3 to the first guide rail 1 side. Less than,
Since the operation of the panel 10 and the operation of the differential body 42 are reverse steps to the operation when the entrance 2 is opened, detailed description thereof will be omitted.

As described above, in this embodiment, the following effects can be obtained by configuring the panel shutter. (1) The differential unit 42 is used to adjust the amount of movement between the first panel 11 and the second panel 12 per time. With this configuration, unlike the related art, there is no need to provide a controller or the like for performing electrical control. As a result, a dedicated program, a sensor for detecting the position of the panel 10, and the like are not required, so that the configuration of the apparatus is simplified and the cost can be significantly reduced. Further, since there is no need to control the number of revolutions of the motor 41, malfunctions of the apparatus can be greatly reduced.

(2) The panel 10 can be moved smoothly by adjusting the amount of movement of the panel 10 per unit time by one motor 41, so that the structure of the apparatus becomes simpler and the cost is reduced. be able to.

(3) When the entrance 2 is closed, the guide rollers 16, 17, 21 are in contact with the guide surfaces 4, 5 of the first guide rail 1. The rattling can be prevented, and the deformation and noise of the panel 10 can be prevented.

(4) The power transmitted to the second panel moving chain 62 via the differential body 42 acts in the direction in which the second guide rail is formed. In the present embodiment, the second support plate 22 is curved toward the direction in which the second guide rail is formed, and the curved side is connected to the second panel moving chain 62 via the chain connector 24. Thereby, power is efficiently transmitted to the second support plate 22, and the panel 10 is smoothly moved.

(5) The second support plate 22 is formed in a substantially O-shape so that the auxiliary guide roller 29 is always in contact with the guide surface 6 of the second guide rail 6. With this configuration, the second panel 12 is moved from the first guide rail 1 (second guide rail 3) to the second guide rail 3 (first guide rail 3).
The operation of moving to the guide rail 1) is smoothly performed, and the guide roller 29 and the second guide rail 3 are moved smoothly.
Generation of a contact sound (separation sound) with the touch panel can be prevented.

(6) The first panel 11 has a small entrance 2
Since a is formed, by opening the sliding door 14 even when the panel 10 is closed, a person, a motorcycle, or the like can enter and exit from the small entrance 2a.

(7) The support plates 18 and 22 are provided rotatably with respect to the panels 11 and 12. Thus, even if the inclination angles of the panels 11 and 12 change, the support plates 18 and 22 always face the direction in which the pulling force of the chains 28 and 62 acts. As a result, the driving force from the motor 41 is efficiently transmitted to the support plates 18 and 22, and thus the chains 28 and 62 can be always held linearly, and the load applied to the chains 28 and 62 can be reduced.

The present invention is not limited to the above-described embodiment, but may be configured as follows without departing from the spirit of the invention. (1) The panel 10 may be composed of one panel without being divided, or may be composed of three or more panels. Even with such a configuration, the same effect as in the above embodiment can be obtained.

(2) As shown in FIG. 11, both the first guide rail 1 and the second guide rail 3 are arranged horizontally. In this case, the chain 77 that applies power to the panel 10 is connected only to the upper side of the panel 10. That is, the lower side of the panel 10 may simply be provided with the roller 78 for guiding the panel 10. With this configuration, the panel 10 can be moved to the side.

(3) Instead of the motor 41 as a driving source, the panel 10 may be moved manually (manually). That is, as shown in FIG. 12, a bevel gear 70 is provided at the end of the side shaft 46 of the differential body 42. Then, a gear box 72 having a handle connecting shaft 71 is installed near the entrance. Then, the gear box 72 and the bevel gear 70 are connected by a shaft 74 to which bevel gears 73 are attached to both ends (only one is shown).

When opening the entrance 2, a predetermined handle 75 is inserted into the handle connection shaft 71 of the gear box 72. Then, by manually turning the handle 75, the side shaft 46 is rotated via the gear box 72 and the shaft 74. Accordingly, power is transmitted to each of the counter shafts 52 and 56, and the panel 10 is moved. When closing the entrance 2, the panel 10 can be lowered by rotating the handle 75 in a direction opposite to the direction in which the entrance 2 was opened.

In the case where the panel 10 is manually moved as described above, the motor 41 is not operated when a power failure occurs.
The panel 10 can be moved even when power cannot be supplied to the panel 10.

(4) As shown in FIG. 13, a coil spring 79 is provided at the lower end of the first guide rail 1. Therefore, when the entrance 2 is closed, the first guide roller 17 is urged upward by the elastic force of the coil spring 79. Therefore, the elastic force of the coil spring 79 is applied to the panel 10 when the entrance 2 where the load is most applied to the motor 41 is opened (when the panel 10 rises). Thus, the load on the motor 41 is reduced, the life of the motor 41 can be extended, and power consumption can be reduced. When the entrance 2 is closed, the coil spring 7
The impact force when the panel 10 comes into contact with the lower surface of the entrance 2 can be reduced by the elastic force of 9.

(5) As shown in FIG. 14, an auxiliary panel 80 is disposed below the second panel 12 so as to be vertically movable with respect to the second panel 12. Then, the coil spring 81 is arranged between the second panel 12 and the auxiliary panel 80. With this configuration, when the doorway 2 is closed, the impact when the panel 10 contacts the lower surface of the doorway 2 can be reduced by the elastic force of the coil spring 81. Further, as shown in FIG. 15, even when the panel 10 does not completely descend to the predetermined position due to an abnormality of the motor 41 or the like. Since the auxiliary panel 80 protrudes downward as much as the coil spring 81 is extended, the entrance 2 can be closed by the auxiliary panel 80.

(6) The chains 28 and 62 as the transmission members used in the above embodiments may be embodied using ball screws. That is, as shown in FIGS. 16 and 17, the shafts 83 and 84 on which the screws are screwed are arranged corresponding to the first guide rail 1 and the second guide rail 3. A bevel gear 85 is provided at the end of each shaft 83, 84.
I support. Then, a ball screw 86 screwed to the shaft 83 is fixed to the support plates 18 and 22.

When the motor is driven, the shafts 83 and 84 are rotated via the differential 42. With the rotation of the shafts 83 and 84, the ball screw 86
The panel 10 moves along the 3,84 screws.

According to this configuration, since the shafts 83 and 84 have higher strength than the chains 28 and 62, a heavier panel (panel) can be moved. (7) In the above embodiment, the first support plate 18 was supported at the lower end of the panel 10. On the other hand, FIG.
As shown in (1), the first support plate 18 is mounted near the second support plate 22. With this configuration, when the panel 10 is fully opened, the lower part of the panel 10 projects forward from the first guide rail 1. This protrusion 87 can be used as a refrigerator.

In this case, since the first support plate 18 is provided near the second support plate 22, the guide roller 17 is also provided near the second support plate 22. Therefore, when the panel 10 is closed, the lower part of the first panel 11 is not fixed by the first guide rail 1 (the first panel 11
Is suspended in the air). Therefore, there is a possibility that the first panel 11 will rattle and the panel 10 will be damaged when a strong wind blows.

In order to prevent this, as shown in FIG. 18 (b), a concave portion 67 is provided on the ground G between the left and right first guide rails 1 as a rattling preventing means. When the panel 10 is closed, the lower part of the first panel 11 is engaged with the concave portion 67, and the movement of the first panel 11 in the front-rear direction is restricted. As a result, the first panel 11 does not rattle due to a strong wind or the like, and the panel 10 can be prevented from being damaged.

(8) As shown in FIG. 19, the first guide rail 1 and the second guide rail 3 are connected by a rotating member 88. Thereby, as shown in FIG. 20, the first guide rail 1 is fixed in the vertical direction, and the second guide rail 3 is fixed in accordance with the inclination angle of the roof 88. As described above, since the first guide rail 1 and the second guide rail 3 are relatively rotatably connected by the rotating member 88, the mounting angle can be easily adjusted, and the workability can be improved.

(9) Differential members are provided at both ends of the counter shafts 52 and 56 for realization. (10) Motor 41
The drive sprocket 40 and the first output side sprocket 50 connected to the first output sprocket 50 are connected via a chain.
The driving force input sprocket 48 and the first input side sprocket 53 are connected via a chain to be embodied.
