(Embodiment) FIG. 1 to FIG. 3 show an eaves automatic overhanging device which is one embodiment of the present invention, in which both vertical frames 1a of a cross-shaped machine frame 1,
A pair of winding shafts 3 for winding the sheet-shaped eave main body 2 is rotatably disposed between the upper portions of the 1a, and a pair of front and rear sides are horizontally extended from the vertical frames 1a, 1a so as to be opposite to each other. Guide arm 4,
4 is provided with laterally long guide holes 5 and 5 over substantially the entire length thereof in the longitudinal direction, and an elongate extension shaft 6 is supported movably in the horizontal direction across the both guide holes 5 and 5, and the elongate extension shaft 6 is supported by the elongate extension shaft 6. The tip ends of the sheet-shaped eaves main bodies 2 are connected.

Further, a spring device 7 for urging the overhanging shaft 6 in the overhanging direction is fixed to the tip end of each guide arm 4, and the rainfall state is detected on the upper surface of the triangular roof-like top plate portion 1b of the machine frame 1. A rain detection sensor 8 is provided, and a hook 9 for suspending a clothesline is provided on the lower surface of each guide arm 4.

As shown in FIG. 4, the two take-up shafts 3, 3 are interlockingly connected by a pair of transmission gears 10, 10, and an operating shaft 11 provided on the vertical frame 1a is rotated in an arrow direction by an operating handle 12. As a result, both winding shafts 3, 3 can be rotated in the winding direction of the eaves main body via the sprocket wheels 13, 14 and the chain 15.

Further, the spring device 7 is composed of a spiral spring 17 whose tip portion is connected to the overhanging shaft 6, and constantly biases the sheet-shaped eaves main body 2 in the overhanging direction.

In FIG. 4, reference numeral 18 denotes the sheet-shaped eave main body 2 and the spiral spring 17
The winding shaft 3 is wound around the winding shaft 3 against the urging force of the winding shaft 3.
A lock device for preventing the rotation of the eaves main body in the extending direction, and a lock piece (19) protruding from the winding shaft (3) and the lock piece (19).
And a locking solenoid (20) for locking and unlocking. Therefore, as shown in FIG. 5a, when the solenoid 20 is energized and the plunger 20a is lowered from the state where the sheet-shaped eaves main body 2 is wound on the winding shaft 3, as shown in FIG. The engagement state between the plunger 20a and the lock piece 19 is released, and the spring device 7 causes the sheet-shaped eaves main body 2 to project.

In FIG. 1, reference numeral 21 is a solenoid limit switch provided at the tip of the guide arm 4, and as described above, the sheet-shaped eaves main body 2 is extended and the eaves extension shaft 6 is extended as shown in FIG. As shown by the phantom line, when the limit switch 21 hits the sensing lever, the limit switch 21 is opened and the energization of the solenoid 20 is stopped.

As shown in FIG. 1, the rain detecting sensor 8 comprises two comb-shaped contacts 8a and 8b arranged on an insulating substrate 22 in an externally exposed state, and both contacts 8a and 8b are about 1 They are close to each other with an interval of about 5 mm, and are installed so that both contacts 8a, 8b are in a conductive state due to water droplets caused by rainfall.

FIG. 6 shows a control device, which is a control box 24.
When the power switch 25 (see FIG. 1) is closed, the control circuit 29 is actuated by the DC power source rectified by the rectifier circuit 28 from the AC power source 26 through the transformer 27, and the contact point 8 of the rain sensor 8 is activated.
When a and 8b are energized to each other due to rainfall and a weak current flows, the oscillator and the amplifier in the control circuit 29 oscillate and increase the power. The contact relay is activated and the solenoid 20 is energized via the changeover switch 30, and as described above, the lock device 18 is unlocked, and the sheet-shaped eaves main body 2 is extended almost simultaneously with rainfall. .

When the solenoid 20 is not energized, the plunger 20a is projected by a relatively loose spring (not shown),
When the operating handle 12 is operated to rotate the winding shaft 3 in the winding direction, the plunger 20a is pushed by hand to lock the locking piece 19. Does not hit the plunger 20a.

When the changeover switch 30 is switched to the right side, the buzzer 31 sounds when it is raining, and the sheet-shaped eaves main body 2 is not extended. In addition,
In FIG. 6, 32 is lit when the power switch 25 is closed,
This is a power lamp that is turned off by opening the solenoid limit switch 21.

Although the AC power supply 26 is used in the above embodiment, a DC power supply such as a dry battery may be used. Also, the power switch 25 may be a push lead type, but if it is a switch that can be turned on and off with a key,
This is preferable from a safety standpoint because the power will not turn on unexpectedly.

According to the present invention, according to the present invention, the base end portion of the sheet-shaped eaves body is wound around the winding shaft, and the tip end portion thereof is connected to the horizontally elongate elongating shaft, and the elongating shaft is extended. A lock device provided with a spring device for urging the eaves in the elongating direction, and for preventing the elevating shaft from rotating in the elongating direction while the eaves body is wound around the winding shaft against the urging force of the spring device. And a rain detection sensor that detects a rainfall state and outputs a signal to the lock device to release the lock state, and winds the eaves body against the biasing force of the spring device from the state in which the eaves body is extended. Since an operation handle for manually rotating the winding shaft to wind the winding shaft is provided, when the above sensor detects a rain condition, the lock signal is unlocked by the detection signal and the spring device extends the overhang. The sheet-shaped eaves body is automatically stretched via the shaft. Therefore, for example, even if you go out with laundry, futon, etc. on the balcony, clothes rack, etc., and even if it rains when you are absent, the laundry will automatically be stretched by the main body of the sheet-shaped eaves. It can be covered to prevent it from getting wet with rain, and when the eaves body is to be wound onto the take-up spindle from the overhanging state as described above, the operating handle can be manually operated to Can be rotated in the eaves winding direction against the biasing force of the spring device, and after the winding is completed, the eaves can be held in a wound state by the locking device.

Thus, according to the device of the present invention, a motor is not used at all as a driving means for rotating the take-up shaft in the overhanging direction and the overwinding direction, and instead of such a motor, the overhanging method is used. Since a spring device for operation and an operating handle for eaves winding are provided, the equipment cost and maintenance cost of the device can be reduced, the device can be made lightweight, and the installation space can be expanded or bulky. Like that,
The appearance can be improved.
