Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a flip-up gate suitable for use in an entrance of a garage or the like.
[0002]
[Problems to be solved by the invention]
As this type of gate door, as described in Japanese Patent Application Laid-Open No. 7-279564, etc., a support, an arm member rotatably supported by the support at one end, and a door attached to the other end of the arm member In addition, there has been known one provided with an elastic force applying means including a coil spring and a gas spring for applying an elastic force to the arm member in the direction in which the door and the arm member are lifted against the dead weight of the door.
[0003]
In addition, when an electric motor is further added to the flip-up type gate described in the above publication, and the arm is automatically rotated by the electric motor to automatically open and close the door, the electric motor Power supply, including insulation work from a 100-volt commercial power supply to the flip-up gate for power supply to the power supply, and unexpected expenses increase, and even after the flip-up gate is installed, the door opens. Power consumption due to operation is incurred and the running cost cannot be ignored. When a commercial power supply of 100 volts is used, the door may not be opened or closed due to a power failure due to a lightning strike or the like.
[0004]
Moreover, in the flip-up type gate that automatically rotates the arm by the electric motor, it is preferable that the door can be manually opened / closed when the door cannot be opened / closed due to a power failure or the like. In this case, a third party who has nothing to do can easily be manually opened and closed from the outside, and such a gate used as a gate of a car garage or the like becomes extremely useless.
[0005]
In addition, in the case of an automatic flip-up type gate, if the operation of the electric motor is stopped after contact with the ground or stopper of the door or arm in order to ensure complete closing and complete opening, The electric motor seems to have been operated in a high load state after the contact until the operation is stopped, which causes anxiety to the operator, shortens the life of the electric motor and increases power consumption. An excessive force is applied to the rotation transmission mechanism that transmits the rotation of the output rotation shaft to the arm. This also shortens the life of the rotation transmission mechanism, and in addition, the inertia of the door or the like due to the weight of the arm or the like. There is a risk that loud noise is generated due to abrupt contact with a stopper or the like.
[0006]
Furthermore, in this kind of flip-up type gate, a gas spring is often used as a balancer that cancels the weight of the electric motor by canceling the weight of the arm, but the elastic force of this gas spring varies considerably with temperature. The opening and closing speeds differ depending on the load fluctuation of the electric motor at high temperature and low temperature, which gives the operator anxiety. In particular, since the flip-up type gate is usually arranged outdoors where the temperature changes drastically, the characteristic fluctuation due to the temperature change of the gas spring cannot be ignored.
[0007]
In addition, in this type of flip-up type gate, the door itself protrudes forward when the door is opened and closed, and there is a risk of unexpected accidents if the door is not opened and closed in consideration of the protruding portion. Opening / closing operation of the door is obstructed, and the door opening / closing operability is extremely poor. Also, if the door is installed in consideration of the protruding portion, the use space in the door becomes narrow.
[0008]
The present invention has been made in view of the above-mentioned points, and its object is to eliminate the need for installation work of a power cable from a commercial power supply of 100 volts, and to significantly reduce running costs even after installation. Another object of the present invention is to provide an automatic flip-up gate that can be opened and closed without being affected by a power failure of a commercial power supply of 100 volts.
[0009]
Another object of the present invention is to provide an automatic flip-up gate that cannot be easily manually opened and closed from the outside during non-power feeding and can be easily manually opened and closed when necessary. It is in.
[0010]
Still another object of the present invention is to avoid a situation in which an electric motor that causes anxiety to the operator is operated in a high load state, To provide a flip-up type gate that can eliminate a crashing into a stopper and the like, can eliminate an unpleasant crashing noise, can save power, and can eliminate a decrease in the life of an electric motor and a transmission mechanism. It is in.
[0011]
Still another object of the present invention is to eliminate temperature dependence, and to avoid a situation in which the opening and closing speeds differ due to load fluctuations of the electric motor at high temperature and low temperature. Then, it is providing the flip-up type gate which can perform desired full closure and full open.
[0012]
Still another object of the present invention is to provide a flip-up type gate that can eliminate the inconvenience of the door as much as possible, eliminates inconvenience such as an accident caused by the protrusion, and widens the use space in the door. There is to do.

The temperature dependency can be eliminated, and the situation where the opening and closing speeds are different due to the load fluctuation of the electric motor at high temperature and low temperature can be avoided, and thus the desired full closing and full opening can be performed. obtain.
[0027]
The flip-up gate according to the tenth aspect of the present invention is the flip-up gate according to any one of the fourth to ninth aspects, wherein the arm means is rotated each time the unit amount of the arm means is rotated. Unit rotation detecting means for detecting movement is further provided. Here, the control means controls the rotation of the arm means based on the detection result of the unit rotation detecting means.
[0028]
The control means in the flip-up type gate of the tenth aspect is preferably unit-rotated by turning the arm means in the direction of raising or lowering the door, like the flip-up type gate of the eleventh aspect of the present invention. The operation of the electric motor of the automatic arm rotation means is stopped when the number of rotations per unit amount detected by the detection means reaches a predetermined value.

[0033]
According to the flip-up type gate of the thirteenth and fifteenth aspects, the operation of the electric motor can be stopped after the rotation of the arm means is decelerated. Therefore, it is possible to accurately and reliably perform the complete closing and the complete opening with a small electric power.
[0034]
Further, according to the flip-up type gate of the thirteenth to sixteenth aspects, after the detection result from the predetermined position rotation detection means occurs, the rotation of the arm means is decelerated or the operation of the electric motor is stopped. In addition, deceleration or deactivation is ensured.

In addition, the electric motor of the automatic arm rotation means when the number of rotations per unit amount detected by the unit rotation detection means from the fully closed door in the rotation of the arm means in the direction of raising the door reaches a predetermined value. Even when the operation of the arm is stopped, as in the flip-up type gate of the nineteenth aspect of the present invention, the unit means for detecting the rotation of the arm means in the downward direction of the door from the fully opened door The number of rotations per unit amount detected reaches a predetermined value. Even when the operation of the electric motor is controlled to decelerate the rotation of the arm means, the door is lowered in the downward direction as in the flip-up type gate of the twentieth aspect of the present invention. The operation of the electric motor of the automatic arm rotation means is stopped when the number of rotations per unit amount detected by the unit rotation detection means from the fully opened door in the rotation of the arm means reaches a predetermined value. It may be.
[0036]
According to the flip-up gates of the seventeenth and nineteenth aspects, since the operation of the electric motor can be stopped after the rotation of the arm means is decelerated, a large electric power is required for stopping the operation of the electric motor. Therefore, it is possible to accurately and reliably perform complete closing and complete opening with small electric power.

It is composed of an encoder that outputs a simple pulse, so that the rotation of the arm means 81 per unit amount is detected every time the arm means 81 rotates. The unit rotation detection means 28 outputs two pulses having different phases and different phases in forward and reverse rotation for each unit rotation of the rotary shaft 37 so that the forward and reverse rotations of the rotary shaft 37 can be identified. It is good that it consists of the encoder which became. As the unit rotation detection means 28, instead of detecting the rotation of the rotary shaft 37, the rotation of the arm means 81 may be detected by detecting the rotation of the shaft member 6. Good.
[0062]
The automatic arm rotation means 29 includes an electric motor 36 with a speed reducer as a power generation source for the rotation of the arm means 81, and a rotation transmission mechanism 60 that transmits the rotation of the rotating shaft 37 of the electric motor 36 to the arm means 81.

The predetermined position rotation detection means 33 includes a disk 49 that is fixed to the shaft member 6 and has an arcuate protrusion 48 integrally, and a limit switch 50 that is attached to the column 2.
[0068]
The predetermined position rotation detection means 33 is configured such that when the shaft member 6 is rotated in the A direction and the arm means 82 is rotated to the predetermined rotation position, the arc projection 48 contacts the limit switch 50 and the limit switch 50 is rotated. And the rotation of the arm means 81 to a predetermined position is detected between the fully opened door and the fully closed door 13 by the operation of the limit switch 50. In this example, the predetermined position rotation detection means 33 is the rotation of the arm means 82 in the A direction, and the arc projection 48 first hits the limit switch 50 at a position 10 degrees before the complete opening as a predetermined position. The limit switch 50 is operated in contact with it, and the operation of the limit switch 50 is maintained until the door is completely opened.
[0069]
Like the electric motor 36, the control means 34 that is operated by being supplied with power from the storage battery 122 is a computer or the like, and is unit rotated by turning the arm means 81 in the upward and downward directions of the door 13, that is, in the A and B directions. When the number of rotations per unit amount detected by the detection unit 28 reaches a predetermined value, the power supply by the storage battery 122 to the electric motor 36 of the automatic arm rotation unit 29 is stopped (non-powered). The arm means 81 is controlled by controlling the operation of the electric motor 36 based on the detection result from the predetermined position rotation detection means 33 in the rotation of the arm means 81 in the A and B directions. The rotation of the motor is decelerated.
[0070]
That is, the control means 34 is a completely closed door shown in FIGS. 1 and 2, and when the switch (not shown) attached to the support column 2 or the like is pressed by the operator, the control means 34 supplies power to the electric motor 36 from the storage battery 122. The electric motor 36 is operated so as to rotate the rotating shaft 37 at, for example, 1700 rpm to 1400 rpm, whereby arm means in the A direction via the rotating shaft 37, spiral gear 39, tooth row 40, cam plate 85 and shaft member 6. 81 is rotated so that the door 13 is flipped up, and after the switch is pressed, the pulse indicating the rotation for each unit amount from the unit rotation detecting unit 28 is counted while the arm unit 81 is rotating in the A direction. Next, a detection result indicating that the arm means 81 has been rotated from the fully opened door to a position 10 ° before the angle is generated from the predetermined position rotation detecting means 33 and this is detected. When the output result is received from the predetermined position rotation detection means 33, the electric motor 36 is operated so as to rotate the rotating shaft 37 by decelerating at, for example, 300 rpm to 500 rpm, and then a pulse indicating the number of rotations per unit amount. When the counted value reaches a value set in advance as the rotational position of the arm means 81 that is fully opened, power supply from the storage battery 122 to the electric motor 36 is stopped (non-power supply) to stop the operation of the electric motor 36. ).
[0071]
10 and 11, when the lower switch 71 of the door 13 is in the fully open state where the position f is shown in FIG. 10 and FIG. The electric motor 36 is reversely operated so that the electric motor 36 is fed to rotate the rotary shaft 37 at, for example, 1700 rpm to 1400 rpm, whereby the rotary shaft 37, the spiral gear 39, the tooth row 40, the cam plate 85, and the shaft member 6 are operated. The arm means 81 is rotated in the B direction through the door to lower the door 13, and after the switch is pressed, the unit means from the unit rotation detecting means 28 during the rotation of the arm means 81 in the B direction. The above-mentioned count value is continuously subtracted with a pulse indicating movement, and the arm means 81 is rotated from the fully closed door to a position 15 ° before the angle. When the electric motor 36 is actuated so as to rotate the rotating shaft 37 at a reduced speed of, for example, 300 rpm to 500 rpm, the number of rotations per unit amount of the arm means 81 is indicated. An electric motor from the storage battery 122 is used to stop the operation of the electric motor 36 when the pulse count value becomes zero. Power supply to 36 is stopped (non-power supply).
[0072]
Further, the control means 34 detects the rotational speed of the rotary shaft 37 from the occurrence time interval of the pulses indicating the rotation for each unit amount from the unit rotation detection means 28, and based on the detection result, the rotary shaft 37 is detected. The rotation speed is controlled so as to be predetermined 1700 rpm to 1400 rpm and 300 rpm to 500 rpm.
[0073]
In the midway stop of the rotation of the arm unit 81 due to an emergency situation, the control unit 34 stores the pulse count value at that time and continues counting or subtracting the pulse by pressing the switch by the operator. .
[0074]
Further, since the rotation position of the arm unit 81 from which the detection result is output from the predetermined position rotation detection unit 33 is known in advance, the control unit 34 receives the detection result from the predetermined position rotation detection unit 33. In this case, if the count value of the pulse is a value that does not correspond to the rotation position of the arm means 81 from which the detection result is output from the predetermined position rotation detection means 33, the count value of the pulse is used as the arm means 81. The value is corrected to a value corresponding to the rotation position.
[0075]
Further, in addition to the limit switch 50, another limit switch is provided to constitute the predetermined position rotation detection means 33, and when the arm means 82 rotates in the B direction, the predetermined position is 15 degrees before the fully closed door. The predetermined position rotation detecting means 33 is configured so that the arc projection 48 first contacts with the other limit switch at the position to activate the limit switch and maintain the operation of the limit switch until the door is completely closed thereafter. In this case, the control unit 34 controls the operation of the electric motor 36 based on the detection result of the other limit switch from the predetermined position rotation detection unit 33 in the rotation of the arm unit 81 in the B direction. The rotation of the arm means 81 may be decelerated.
[0076]
Further, without providing the predetermined position rotation detection means 33, the rotation of the arm means in the A direction is detected by the unit rotation detection means 28 from the completely closed door, similarly to the rotation of the arm means 81 in the B direction. The control unit 34 controls the operation of the electric motor 36 to decelerate the rotation of the arm unit 81 when the count value of the pulse indicating the number of rotations per unit amount reaches a predetermined value. May be configured.
[0077]
The locking means 58 includes an electromagnetic clutch having an electromagnet, a spring, a movable iron piece, a friction plate, and the like. The locking means 58 supplies power to the electric motor 36 of the automatic arm rotation means 29 and supplies power from the storage battery 122 to the electromagnet. The electromagnetic force is generated, and the movable iron piece and the friction plate are moved against the spring force of the spring with this electromagnetic force to release the braking to the rotating shaft 37 of the electric motor 36 and to enable the rotating shaft 37 to rotate. When the automatic arm rotating means 29 is not supplied with power to the electric motor 36, the electromagnet is also supplied with power, and the rotation shaft 37 of the electric motor 36 is subjected to friction braking of the friction plate based on the spring force of the spring to inhibit the rotation of the rotation shaft 37. It is like that.
[0078]
Thus, when the electric motor 36 is de-energized, the locking means 58 applies braking to the rotating shaft 37 of the electric motor 36 so that the rotating shaft 37 cannot rotate. The arm means 81 connected via the tooth row 40, the cam plate 85 and the shaft member 6 is also prevented from rotating in the A and B directions, and the rotation of the arm means 81 is prohibited.
[0079]
The release means 59 is connected to a release lever 72 disposed on the lock means 58 so as to be swingable so as to release the frictional braking by moving the friction plate against the spring force of the lock means 58, and one end connected to the release lever 72.

It is arranged.
[0080]
The release means 59 is configured such that when the grip member 74 is pulled manually and the wire 73 is pulled when necessary during the non-power supply to the electric motor 36 such as when the predetermined electric power for operating the electric motor 36 cannot be obtained. The release lever 72 is swung. When the release lever 72 is swung by being pulled by the wire 73, the friction braking based on the spring force on the rotating shaft 37 of the electric motor 36 in the locking means 58 is released by the lever principle. Thus, the releasing means 59 releases the frictional braking in the locking means 58 during the non-power supply to the electric motor 36, and the spiral gear 39, the tooth row 40, the cam plate 85 on the rotating shaft 37 of the electric motor 36. And the prohibition of the rotation of the arm means 81 connected via the shaft member 6 is released. When the prohibition of the rotation of the arm means 81 by the locking means 58 is thus released, the arm means 81 can be manually rotated in the A and B directions so that the door 13 can be opened and closed manually. Become.
[0081]
The pin 73 attached to the support column 2 so that the wire 73 drawn out from the hole 76 can be wound or the grip member 74 moved to pull the wire 73 is attached to the support column 2 so as to be detachable. The release means 59 is further provided with a holding tool or the like, and the release state with respect to the locking means 58 can be maintained by winding the wire 73 around the pin or holding the grip member 74 on the holder. Good.
[0082]
In the flip-up type gate 1 described above, when the door is completely closed, the door 13 is substantially upright on the ground surface 55 as shown in FIGS. 1 and 2. In this state, the operator operates a switch (not shown) to supply power to the electric motor 36 and the locking means 58 to operate the electric motor 36, while the locking means 58 brakes the rotating shaft 37 of the electric motor 36. When the main arm member 8 is released in the A direction via the spiral gear 39, the tooth row 40, the cam plate 85, and the shaft member 6 by the rotation of the rotary shaft 37 by the operation of the electric motor 36, the main arm The connecting member 16 having the one end 14 connected to the member 8 via the shaft member 15 is dragged by the main arm member 8 while being rotated in the F direction with respect to the main arm member 8. The part 24 is guided by the guide passage 52 through the rotation of the roller 53 and is lifted. As a result, the auxiliary arm member 21 is pulled slightly toward the support column 2 as a whole, and the door 13 is pulled by this pulling. The door 13 is rotated in the D direction with respect to the other end portion 10 of the arm member 8. Therefore, the lower end 71 of the door 13 does not protrude forward as shown by the trajectory abc in FIG. After the main arm member 8 is rotated in the A direction from the fully closed position (position shown in FIGS. 1 and 2) to about 15 °, the main arm member 8 moves in the A direction. As the door 13 rotates, the lower end 71 of the door 13 slightly protrudes forward and rises along a trajectory cdef shown in FIG. The power supply to 36 and the locking means 58 is stopped, the operation of the electric motor 36 is stopped, and the locking of the rotating shaft 37 of the electric motor 36 by the locking means 58 is performed. The main arm member 8 and the auxiliary arm member 21 extend so as to intersect with each other while the lower end 71 rises with the f from the locus e.
[0083]
In order to change from the fully open door to the fully closed door, the main arm member 8 may be rotated in the B direction via the shaft member 6 by the reverse operation of the electric motor 36 by the operation of a switch (not shown) by the operator. Even when the door 13 is shifted to a fully closed door, the lower end 71 of the door 13 descends with a trajectory fedcba-a shown in FIG.
[0084]
The flip-up type gate 1 includes a solar cell 121 that generates electric power for operating the electric motor 36, and the solar cell 121 is provided on the column 2, and therefore the power cable from a commercial power supply of 100 volts is used. Installation work can be dispensed with, and after installation, solar energy can be used to significantly reduce running costs, and the door 13 can be opened and closed without being affected by a 100-volt commercial power failure. Even if not, the electric motor 36 can be operated with the electric power of the storage battery 122 obtained in advance by the solar battery 121, the solar energy can be effectively used without waste, and the storage battery 122 is arranged in the support column 2. Since the solar cell 121 is installed on the ceiling surface 123 of the column 2, the electrical wiring relating to the storage battery 122 and the solar cell 121 is performed. Can be carried out in one of the struts, on which it is possible to easy to reduce the installation cost and installation work, the sunlight can be effectively utilized for post 2 is usually placed outdoors.
[0085]
In the flip-up type gate 1, the coil spring 96 generates a contraction elastic force that appropriately cancels the weight of the door 13 and the like, so that the meshing portion between the spiral gear 39 and the tooth row 40 in the fully closed door. Therefore, the door opening operation by the operation of the electric motor 36 can be performed without difficulty. When the arm means 81 is rotated in the A direction by the operation of the electric motor 36, the cam plate 85 is similarly rotated in the A direction as shown in FIG. The self-weight of the door 13 and the like is appropriately canceled out by the tensile elastic force of the coil spring 96 generated correspondingly to enable automatic opening without difficulty.
[0086]
In the flip-up type gate 1, since the contraction elastic force for rotating the arm means 81 in the A direction of the door 13 is generated only by the coil spring 96, temperature dependency can be eliminated as compared with the gas spring. As a result, it is possible to avoid a situation in which the opening and closing speeds differ due to load fluctuations of the electric motor 36.
[0087]
According to the flip-up type gate 1, the rotation of each unit amount detected by the unit rotation detecting means 28 that detects the rotation of each unit amount of the arm means 81 for every rotation of the unit means of the arm means 81. Since the operation of the electric motor 36 of the automatic arm rotation means 29 is stopped when the count value of the pulse corresponding to the number of times reaches a predetermined value, in other words, the rotation position of the arm means 81 Since the operation of the electric motor 36 is stopped based on the detected rotation position, the door 13 and the arm means 81 are completely closed and opened without contacting the ground and the stopper. It is possible to avoid the situation where the electric motor 36 which can realize the door reliably and thus causes anxiety to the operator is operated under a high load state, and uncomfortable clash when the door is completely closed and opened. Sound Was obtained. Moreover, may eliminate the reduction in the life of the rotation transmitting mechanism 60 including an electric motor 36 and the spiral gear 39 and teeth 40 on which may play a power saving.
[0088]
According to the flip-up gate 1, the detection result from the predetermined position rotation detection means 33 is used to control the rotation of the arm means 81 based on the detection result from the predetermined position rotation detection means 33. As a result of being usable as the reference position, the rotation control of the arm means 81 by the unit rotation detection means 28 can be performed with reliability.
[0089]
Further, in the flip-up type gate 1, since the one end portion 94 of the coil spring 96 is connected to the other end portion 91 of the roller chain 90 that is bent and guided against the cam edge 89 of the cam plate 85, the coil spring 96. As a result, it is possible to make a desired rotational moment to be applied to the cam plate 85 based on the tensile elastic force of the arm plate 81 regardless of the rotational position of the cam plate 85.
[0090]
In addition, according to the flip-up type gate 1, in order to stop the operation of the electric motor 36 after the rotation of the arm means 81 is decelerated, a large amount of electric power is not required for stopping the operation of the electric motor 36, and a small electric power is required. Thus, the complete closing and the complete opening can be performed accurately and reliably.
[0091]
Further, in the flip-up type gate 1, the door 13 is rotated in the direction to eliminate the protrusion of the lower end 71 of the door 13 when the door 13 is opened, and thus the protrusion of the door 13 to the front can be eliminated as much as possible. Inconveniences such as accidents and deterioration in operability are eliminated, and the use space in the door can be widened.
[0092]
According to the flip-up type gate 1, since the locking means 58 prohibits the automatic arm rotation means 29 from being de-energized to the electric motor 36 and the arm means 81 from being rotated, it is easy from the outside during non-power supply. When the door 13 cannot be manually opened and closed and the release means 59 is manually disposed on the column 2 so that a predetermined power sufficient to operate the electric motor 36 cannot be obtained. The unlocking means 59 can release the locked state of the locking means 58, and the door 13 can be easily opened and closed manually from the inside.
[0093]
The release means 59 may be configured as shown in FIG. 12. The release means 59 shown in FIG. 12 is disposed in the support 77 and the housing 77 attached to the support column 2 in addition to the release lever 72. A slide knob 78 and a coil spring 79 disposed in the housing 77 and elastically biasing the slide knob 78 to return to the original position are provided. The housing 77 has an engagement hole 80. The slide knob 78 is formed integrally with the main body 110 slidably disposed in the housing 77 and one surface of the main body 110 and through the hole 111 of the housing 77. A knob 112 that protrudes outward and is disposed on the column 2, a protrusion 113 that is integrally formed on one surface of the main body 110, and a portion that is integrally formed on the other surface of the main body 110. Through the through hole 114 formed in the support 2 is provided with an engaging protrusion 115 to be engaged with the release lever 72.
[0094]
According to the release means 59 shown in FIG. 12, the release lever 72 can be swung via the engaging protrusion 115 by manually moving the knob 112 and sliding the slide knob 78 downward. Thus, the prohibition of the rotation of the arm means 81 can be released. In the release means 59 of FIG. 12, the protrusion 113 is inserted into the engagement hole 80 when the slide knob 78 is slid downward, so that the swinging state of the release lever 72 can be maintained. The release lever 72 is released from the swinging state by manually pressing the slide knob 78 toward the support column 2 via the knob 112 to extract the protrusion 113 from the engagement hole 80, and thereby rotating the coil spring. 79 can be performed by sliding the slide knob 78 upward.
[0095]
Further, the release means 59 may be configured as shown in FIGS. 13 and 14, and the release means 59 shown in FIGS. 13 and 14 includes a release lever 72 that protrudes out of the column 2 through the through hole 114, and a column. 2 and a leaf spring 118 which is fixed to the inner surface and bends and protrudes at the center, and the release lever 72 has a bifurcated portion 119 as a knob on its free end side, The leaf spring 118 is fixed to the inner surface of the column 2 with a screw or the like through between the bifurcated portions 119 disposed on the column 2. In the release means 59 of FIGS. 13 and 14, the prohibition of the rotation of the arm means 81 can be released by manually moving the bifurcated portion 119 and directly swinging the release lever 72. Since the base of the bifurcated portion 119 of the release lever 72 moves over the bent and protruded portion of the leaf spring 118 with the spring deformation of the leaf spring 118, the release lever 72 is engaged. The release lever 72 is directly and manually swung in the opposite direction to the above, and the bent portion of the leaf spring 118 with the spring deformation of the leaf spring 118 and the base of the bifurcated portion 119 By releasing the engagement, the swinging state of the release lever 72 can be released.
[0096]
