In addition, the other joint arm 32 is connected so that the distal end side thereof rotates in a substantially horizontal direction with respect to the opening / closing body supporting front frame 11.

  The arm bracket 33 is fixed to a drive shaft 53 of a swinging electric drive unit 50 described later and protrudes forward, and swings up and down as the drive shaft 53 rotates.

The support base 40 is a long prismatic member continuous in the lateral width direction of the opening / closing body 10, and is formed slightly longer than the dimension of the opening / closing body 10 in the lateral width direction.
The support base 40 is fixed to a building or the like, which is an installation target of the awning device 1, by a plurality of mounting brackets 41 fixed at midway positions in the longitudinal direction.
A bearing bracket 42 that rotatably supports the drive shaft 53, a winder support bracket 43 that rotatably supports the winder 20, and a middle part of the swinging electric drive unit 50 are supported on the support base 40. The support bracket 44 and the base end side support bracket 45 that supports the base end side of the swinging electric drive unit 50 are fixed so that they cannot rotate and cannot move in the axial direction.

  The bearing brackets 42 are respectively disposed on one end side and the other end side of the support base 40. The bearing bracket 42 is fixed in a non-rotatable manner by being annularly attached to the prismatic support base 40, and the protruding tip side is directed obliquely downward to the front side. The tip end portion of the drive shaft 53 of the portion 50 is inserted and supported rotatably.

The winding body support bracket 43 is fixed to be non-rotatable by being annularly attached to the prismatic support base 40, and the protruding tip side is directed obliquely upward to the front. The handle 20 is rotatably supported.

  The midway support bracket 44 is provided at a position away from the winding body support bracket 43 toward the center in the lateral width direction of the opening / closing body. The intermediate support bracket 44 is mounted in an annular shape with respect to the prismatic support base 40 so as to be non-rotatable, and the protruding tip side is directed obliquely forward and downward. The rotary shaft of the rotary electric motor 51 constituting the drive unit 50 is rotatably supported, and a gear portion 52 constituting the swinging electric drive unit 50 is supported at a portion closer to the tip than the support portion.

  The proximal end side support bracket 45 is provided at a position spaced apart from the intermediate support bracket 44 in the lateral direction of the opening / closing body and closer to the center in the longitudinal direction of the support base 40. The base end side support bracket 45 is fixed in a non-rotatable manner by being annularly attached to the prismatic support base 40, and the base 51a of the swinging electric drive unit 50 is supported by a portion protruding from the outer surface of the support base 40. Support non-rotatable.

The swinging electric drive unit 50 includes a rotary electric motor 51 that rotates in both directions, a gear unit 52 that appropriately adjusts and outputs the rotational speed and rotational force of the rotary electric motor 51, and an output side of the gear unit 52.

Two swinging electric drive units 50 are provided such that the drive shaft 53 is supported by the bearing bracket 42 in a direction opposite to each other.

The rotary electric motor 51 is an electric motor (for example, a tubular motor) having a base 51 a (see FIG. 2) and a rotating part 51 b that rotates around the base 51 a, and the center of rotation is parallel to the winding body 20. And is supported by the support base 40 so as to be close to the support base 40.
According to the illustrated example, the base 51 a is formed in an axial shape substantially parallel to the support base 40, and is fixed to the support base 40 so as not to rotate by way of the base end side support bracket 45.
The rotating portion 51b is formed in a substantially cylindrical shape covering the periphery of the base portion 51a, and the rotating shaft 51b1 protrudes integrally at the distal end side thereof. The rotating portion 51b1 is inserted into the intermediate support bracket 44 and is rotatably supported. The

The gear unit 52 is a gear mechanism that decelerates the rotational speed of the rotary shaft 51b1 of the rotary electric motor 51 and increases the rotational force for output.
The gear portion 52 is configured to receive the rotational force of the rotary electric motor 51 on the central axis of the rotary electric motor 51 and output it at a position shifted from the central axis. According to this configuration, the rotating drive shaft 53, the arm bracket 33, and the like are prevented from interfering with the stationary members on the support base 40 side (for example, the support base 40, the winding body support bracket 43, etc.). The relatively long rotary electric motor 51 can be disposed in the vicinity of the support base 40. As a result, the amount by which the rotary electric motor 51 protrudes diagonally forward and downward of the support base 40 can be reduced. .

Further, the gear portion 52 in the illustrated example constitutes a worm gear in which worms 52a and 52c on the drive source side and worm wheels 52b and 52d on the opposite drive source side are engaged with each other.
More specifically, the gear unit 52 includes a worm 52a connected on the axis of the rotary shaft 51b1 of the rotary electric motor 51, a worm wheel 52b that meshes with the worm 52a with the axis substantially orthogonal thereto, and the worm wheel.

The drive shaft 53 is connected on the line. The worm wheel 52b and the worm wheel 52d are rotatably supported with respect to the midway support bracket 44 via a support case 52e.
According to this configuration, when the rotary electric motor 51 is stopped, the drive shaft 53 tries to rotate due to the weight of the telescopic arm 30 and the opening / closing body support front frame 11 and the like. 52c and the worm wheels 52b and 52d on the counter driving source side can be blocked by meshing.
According to the illustrated example, the support case 52e is provided so as to cover and support all the two sets of worm gears. However, as another example, two support cases are provided so as to cover and support the two sets of worm gears. It is also possible to replace the support case with the support case or use a bracket that exposes and supports each worm gear.

The drive shaft 53 is a shaft-like member that is substantially parallel to the support base 40. One end of the drive shaft 53 is connected to a worm wheel 52d on the output side of the gear portion 52, and is rotatably supported on the midway support bracket 44 via a support case 52e of the gear portion 52. The other end side of the drive shaft 53 is inserted into the bearing bracket 42 and is rotatably supported.
The drive shaft 53 receives the rotational force of the rotary electric motor 51 through the gear portion 52 and rotates.

In the figure, reference numeral 61 denotes an upper cover that covers the upper side of the support base 40 and the winding body 20, and reference numerals 62 and 62 denote side covers that cover the sides of the support base 40 and the winding body 20 and the like. .
Although not shown, the awning device 1 includes an operation switch and a control for controlling a rotary drive source (not shown) in the winding body 20 and the rotary electric motor 51 of the swinging electric drive unit 50. The parts are electrically connected.
The operation switch includes a switch for rotating the rotary electric motor (not shown) in the winding body 20 in the feeding direction, a switch for rotating the rotary electric motor in the reverse direction, and a plurality (two in the illustrated example). Corresponding to each of the rotary electric motors 51, a switch for rotating each rotary electric motor 51 to one side, a switch for rotating each rotary electric motor 51 in the reverse direction, and the like are provided.
The control unit may be a rotary electric motor (not shown) in the winding body 20 or a plurality of rotary types according to a signal input from the operation switch or a signal input from another sensor or device. An electric circuit that emits a signal for controlling the electric motor 51. For example, a programmed logic circuit using a microcomputer circuit or a sequencer, a wired logic circuit using an electronic circuit, a relay circuit, or the like, or an appropriate combination thereof Circuit.

When the control unit is operated to store the opening / closing body 10 by a signal from the operation switch or the like, when the opening / closing body 10 is wound around the winding body 20 and all of the plurality of telescopic arms 30 are contracted, The plurality of swinging electric drive units 50 are controlled so that the plurality of telescopic arms 30 are all at the same angle.
Hereinafter, this control will be described in detail with reference to the flowchart shown in FIG.

First, the control unit determines whether or not the opening / closing body 10 is at the storage position (step 1). If the opening / closing body 10 is at the storage position, the process proceeds to the next step 2; To do.
Here, the storage position means a state where the winding body 20 winds the opening / closing body 10 and the telescopic arm 30 is substantially contracted. Whether or not the opening / closing body 10 is in the retracted position is determined by, for example, a detection switch (for example, a counter-type limit switch) that operates according to the amount of rotation of the winding body 20 or the rotary electric motor in the winding body 20. It may be determined by the presence or absence of a signal from the detection switch. That is, the detection switch is provided to output a contact signal when the amount of rotation of the winding body 20 or the rotary electric motor in the winding body 20 is a predetermined value or less. When there is an input contact signal, it is determined that the opening / closing body 10 is in the retracted position.

In step 2, the presence / absence of the opening / closing body housing signal is determined. If there is an opening / closing body housing signal, the process proceeds to the next step 3, and if not, the flowchart is ended.
The opening / closing body storage signal is a signal for storing the opening / closing body 10 in a fully deployed state or a halfway position to the storage position, and is generated by, for example, operating the operation switch. Signal.

  In step 3, the rotary electric motor in the winding body 20 is rotated to rotate the winding body 20 in the winding direction so that the opening / closing body 10 is wound around the winding body 20, and a plurality of telescopic arms 30 is contracted against a biasing force of a biasing member (not shown).

  In step 4, it is determined whether or not the opening / closing body 10 is in the storage position. If the opening / closing body 10 is in the storage position, the process proceeds to the next step 5; Continue rotating in the winding direction. In this step, whether or not the opening / closing body 10 is in the retracted position is determined according to the amount of rotation of the winding body 20 or the rotary electric motor in the winding body 20 as in step 1 above. What is necessary is just to judge by the presence or absence of the signal of a detection switch.

In step 5, the rotation of the winding body 20 is stopped by stopping a rotary electric motor (not shown) in the winding body 20.
In addition, the rotary electric motor in the winding body 20 is configured so that the output shaft does not freely rotate when stopped. In this configuration, for example, a brake mechanism that locks or releases the rotary shaft may be provided in the rotary electric motor.

  In step 6, the arm bracket 33, the telescopic arm 30, the opening / closing body supporting front frame 11, the opening / closing body 10 and the like are moved upward by driving the swinging electric drive section 50 for all of the plurality of swinging electric drive sections 50. Swing (see FIG. 3). More specifically, by supplying electric power to the rotary electric motor 51 of the swinging electric drive unit 50, the rotary electric motor 51 is rotated and the drive shaft 53 is rotated by the rotational force of the rotary electric motor 51. Thus, the arm bracket 33, the telescopic arm 30, the opening / closing body supporting front frame 11 and the opening / closing body 10 are swung upward.

In step 7, it is determined whether or not the angle of the opening / closing body 10, that is, the angle of the telescopic arm 30 has reached the upper limit. If the upper limit (see the two-dot chain line in FIG. 3) has been reached, go to the next step 8. Proceed with the process, otherwise continue the upward swinging at step 6.
Here, the determination as to whether or not the opening / closing body 10 and the telescopic arm 30 have reached the upper limit is based on the presence or absence of a signal from a limit switch (not shown) provided in the swinging electric drive unit 50. The limit switch is a contact-type switch or non-contact-type switch (for example, a counter-type switch, an encoder switch, a hall sensor, etc.) that operates when a rotation part such as the rotation shaft 51b1 or the drive shaft 53 reaches a predetermined rotation amount. ) Or a contact type switch or a non-contact type switch (for example, a micro switch, a proximity switch, a hall sensor, etc.) provided to operate when a swinging portion of the arm bracket 33 or the like swings upward by a predetermined amount. ) Etc.
The upper limit angle is appropriately set so that snow and rain flow on the opening / closing body 10 without stagnation.

  In step 8, the swinging of the telescopic arm 30 and the opening / closing body 10 is stopped by cutting off the power supplied to the rotary electric motor 51 of the swinging electric drive unit 50 for all of the plurality of swinging electric drive units 50. To do. During this stop, the arm bracket 33, the telescopic arm 30 and the like swing downward due to the weight, so that the worms 52a and 52c on the drive source side and the worm wheels 52b and 52d on the counter drive source side in the gear portion 52. Can be blocked by meshing with.

Although not described with reference to the flowchart, the control unit receives a stop signal as a signal emitted from the operation switch, a sensor, or the like. The rotary electric motor is stopped and the swinging electric drive unit 50 is stopped.
In addition, when the control unit receives a signal for deploying the opening / closing body 10 as a signal generated from the operation switch, sensor, or the like, Rotate the rotary motor.
In addition, when the control unit receives a signal for swinging the opening / closing body 10 upward or downward as a signal generated from the operation switch, sensor, or the like, the control unit may Alternatively, the rotary electric motor 51 is rotated so as to swing downward.

Therefore, according to the awning device 1 having the above-described configuration, the two swinging electric drive units 50 and 50 can be individually controlled, and thereby the left and right tilt angles of the opening / closing body 10 can be easily adjusted. Can do. For example, only the left swinging electric drive unit 50 is rotated to tilt only the left side of the opening / closing body 10 downward, or conversely, only the right swinging electric drive unit 50 is rotated to rotate the right side of the opening / closing body 10. The opening / closing body 10 can be brought into an appropriate inclined state according to the state of sunshine, wind and rain, and the like.
In addition, since the swinging electric drive unit 50 is provided in the lateral width direction in the vicinity of the support base 40, there are few portions protruding downward on the support base 40, and consequently, parts or the like protruding downward are related to the awning. It can prevent that the installation object (building etc.) of the apparatus 1 interferes, or the components etc. which protrude below damage the design appearance of the awning apparatus 1 from being damaged.
Further, since the drive shaft 53 for swinging the telescopic arm 30 is supported by the support base 40 via the bearing brackets 42 on the both sides in the axial direction and the intermediate support bracket 44, the telescopic arm 30 is swung. The structure that can be supported can be configured to be robust and have good operability.
Further, when the opening / closing body 10 is wound around the winding body 20 and all of the plurality of telescopic arms 30 are contracted, when the opening / closing body 10 is in the retracted position, the plurality of telescopic arms 30 are all at the same angle. The design appearance in the retracted state of the opening / closing body 10 can be improved.

  According to the above embodiment, the telescopic arm 30 is contracted so as to be folded. However, the telescopic arm 30 may be configured to contract in the deploying and storing direction of the opening / closing body 10. As another example, it is also possible to adopt a mode in which a plurality of cylinders having different outer diameters are overlapped in the radial direction, and the inner and outer cylinders slide in the axial direction and contract, or other structures. .

  In the above embodiment, the gear portion 52 is composed of a plurality of sets of worm gears. However, as another example, a single worm gear and another power transmission mechanism (for example, a gear mechanism using a spur gear or a bevel gear, a belt, etc. And a transmission mechanism using a pulley, a transmission mechanism using a chain and a sprocket, etc.), or a configuration using only the other power transmission function.

  Moreover, in the said Example, although the axis line of the rotary electric motor 51 and the axis line of the drive shaft 53 were shifted, as another example, the input side gear in the gear part 52 and the output side gear are arrange | positioned on the same straight line. Thus, a configuration in which the axes are arranged on the same straight line is also possible. Furthermore, as another example, the gear portion 52 may be omitted and the rotary shaft 51b1 of the rotary electric motor 51 and the drive shaft 53 may be directly connected.

  In the above-described embodiment, the rotation of the drive shaft 53 due to the weight of the telescopic arm 30 or the like is suppressed by the meshing between the worms 52a and 52c on the drive source side and the worm wheels 52b and 52d on the counter drive source side. However, as another example, when the rotary electric motor 51 is stopped, a brake pad (not shown) is slidably contacted or meshed with a rotating portion (for example, the driving shaft 53 or the rotating portion 51b) to suppress the rotation of the driving shaft 53. It is also possible to have a structure that

  In the above embodiment, when the opening / closing body 10 is set to the retracted position, the opening / closing body 10 and the telescopic arm 30 are stopped at the upper limit of the swing range. The telescopic arm 30 and the like can be stopped at the lower limit of the swing range, or can be stopped at a midpoint of the swing range.

  In the above embodiment, the opening / closing body 10 is unfolded or stored by operating an operation switch (not shown), or the rotary electric motor 51 is rotated to change the inclination angle of the left and right telescopic arms 30. However, other examples include one or more types of sensors such as a sunshine sensor, illuminance sensor, wind sensor, snow cover sensor, rain sensor, temperature sensor, fire sensor, smoke sensor, etc. Accordingly, it is possible to adopt a configuration in which the unfolding operation, the storing operation, the change of the inclination angle, and the like are automatically performed.

  Further, as a configuration added to the above-described embodiment, a configuration in which the deployment operation, the storage operation, the change of the inclination angle, and the like are automatically performed so as to follow the movement of the sun can be employed.
