EMBODIMENT OF THE INVENTION Hereinafter, in order to specifically explain the present invention, one embodiment thereof will be described in detail based on the drawings.

FIG. 2 shows its plan view, FIG. 2 shows its front view, and FIG. 3 shows its side view. In addition, Figures 4 to 7 are explanatory diagrams of the operation of each link mechanism of the fully automatic bag storage device, and Figures 8 (A) and (B) show an umbrella storage bag used in the fully automatic bag storage device. .

The fully automatic bag storage device of this embodiment (it has two link mechanisms as shown in the table), one of which has a guide ring 10 that serves as a guide when storing an umbrella in an umbrella storage bag. This is a guide ring link mechanism 20 that opens from the state shown in the figure to the state shown in the operation explanatory diagram of FIG. 4 to facilitate taking out the umbrella stored in the umbrella storage bag. This is an opening link machine 1i30 which is installed at the lower part of the ring link machine 1'i20 and is used to open and replenish an umbrella storage bag directly below the center hole 10a of the guide ring 10.

Also, these two linkages 20.30 need to operate in synchronization with each other. Therefore, the fully automatic bag storage device 1 of this embodiment uses a servo motor 4° as a single drive source, and adopts a configuration in which the two link mechanisms 20 and 30 are driven in complete synchronization.

First, the guide ring link mechanism 20 will be explained. When a predetermined operating input is applied, the rotating shaft 40a of the servo motor 40 rotates in the direction of the arrow shown. On this rotating shaft 40a, an eccentric shaft 40 eccentrically from the central axis
b stands upright, and as shown in FIG. 1, the arm 20a is biased by a coil spring 20b so as to come into contact with the eccentric shaft 40b. Therefore, the armrest 20 a [;&
When the servo motor 40 rotates once, it swings only once about the fulcrum 20c. Each of the bars 20d to 20 that constitutes the steering mechanism 20 uses this vibration as a driving force.
j[& The operation starts from the state shown in FIG. 1, passes through the states shown in FIGS. 4 and 5, and returns to the state shown in FIG. 1 again.

That is, as shown in FIG. 4, the arm 20a is connected to the eccentric shaft 40.
When pushed up by bar 20d, bars 20e and 2Of are applied to the vehicle via bar 20d. The par 20e, 2Of
The other ends are linked to bars, 20g and 20h, which rotate with the main body of the automatic umbrella bag storing device as a fulcrum, so that they draw a circular orbit and approach each other as shown in FIG. Due to this movement, the bars 20i and 20j similarly approach each other, and a guide ring rotatable by 20+ is attached to the support 20]O
The movable parts 10b and 10c are rotated so as to be separated from each other, and the guide ring 10 is opened.

Then, when the servo motor 40 further rotates, the arm 20a returns to its original position due to the elastic force of the coil spring 20b, and the movable portion 10b of the guide ring 10.

10c is also integrated with the fixed portion 10d of the guide ring 10, as shown in FIGS. 5 and 1.

Incidentally, fan-shaped guide pieces 10e made of an elastic material are attached to the bottom surfaces of the movable parts 10b and 10c of the guide ring 0 to ensure guidance when inserting the umbrella into the umbrella storage bag, as will be described later.

Next, the opening link mechanism 30 will be explained.

The opening link mechanism 30 is a link mechanism operated by a crank bar 30a that is rotatably fitted to the eccentric shaft 40b, and the crank bar 30a is linked to an opening arm 30b that is rotatable around the support 201. . FIGS. 6 and 7 1: An enlarged explanatory view of the operating portion of this opening link mechanism 30. A movable arm 30d, which is movable only in the direction of the arrow in FIG. 7 by a spring 30c, is attached to the tip of the open arm 30b, which rotates as described above.

An adhesive that adheres to the umbrella storage bag 50 (described later) is applied to the tip of the movable arm 30d.

That is, when the crank par 30a is in the state shown in FIG. 1, the open arm 30b and the movable arm 30d are integrated in a substantially continuous curve due to the biasing force of the spring 30c, and the tip of the movable arm 30d is connected to the guide. Ring moving part 10b, 1
It is located directly below the joining position of 0c. From this state, when the crank par 30a is pulled up by the rotation of the servo motor 40, the opening arm 30b and the movable arm 30d rotate together around the support 201, as shown in FIG. Like the ring movable parts 10b and 10C, it operates so as to pop out from the main body of the automatic umbrella bag storage device.

Then, the servo motor 40 rotates and the crankper 30
When a is pushed down, the open arm 30b and the movable arm 3
0d rotates in the opposite direction, and when the crank par 30a is pushed down the most, the tip of the movable arm 30d is directly below the fixed part 10d of the guide ring 10, as shown in the operation explanatory diagram of FIG. reach up to.

Next, the shape of the umbrella storage bag used in the automatic bag storage device and its attachment to the fully automatic bag storage device will be explained.

FIGS. 8(A) and 8(B) IIm show sectional views from the front medical side of the umbrella storage bag 50. Umbrella storage bag 50 as shown
(Two roughly rectangular bag pieces 50a and 50b are joined together at their side and bottom surfaces to form a bag shape.Also,
One bag piece 50b is slightly longer than the other bag piece 50a, so there is a step at the opening of the umbrella storage bag 50, and a round hole 50c is formed in the step. And this round hole 5
A perforation 50d is formed along the upper end so that 0c can be easily broken.

A large number of umbrella storage bags 50 having such a shape are attached to an automatic bag storage device for overlapping umbrellas in the following manner.

As clearly shown in the side view of FIG. 3, a single mounting rod 60a protrudes from the back to the front of the 1-mm automatic umbrella bag storing device. The stopper 60b is fitted into the stopper 60b. Further, a biasing plate 60d that is constantly biased toward the front by a spring 60c is fitted onto the mounting rod 60a. Mounting of the umbrella storage bag 50 is carried out by removing the stopper 60b from the mounting rod 60a and inserting the mounting rod 60a into the round hole 50c against the biasing force of the biasing plate 60d. Umbrella storage bag 50 (t, spring 60c and biasing plate 60d) attached in this way
Therefore, it is always positioned so as to be in contact with the stopper 60b.

That is, the positional relationship between the stopper 60b and the umbrella storage bag 50 is exactly as shown in FIG. 6.

It should be noted that the automatic umbrella bag storage device of this embodiment uses airflow to make it easier to form an opening in the umbrella storage bag 50.In order to create this airflow, a compressor is installed in the automatic umbrella bag storage device. This compressor 70a has a built-in
A blowing lower blower 0b for compressed air is provided at a fixed portion 10d of the guide ring 10 (see FIG. 6).

Further, in order to automatically detect whether or not an umbrella is inserted, a pair of beam sensors 80 are embedded in the fixed portion 10d of the guide ring 0 (see FIG. 6).

The automatic umbrella bag storage device of this embodiment configured as described above has the effect of easily forming an opening in the umbrella storage bag 50 in the manner described above, thereby making it possible to store umbrellas reliably and easily.

First, the umbrella storage bag 50 is attached (this is done after the servo motor 40 is rotated approximately half a turn to operate the guide ring link mechanism 20 and the opening link mechanism 30, and the automatic umbrella bag storage device is brought into the state shown in FIG. 4). .

- After completing the installation of the umbrella storage bag 50, the servo motor 40 is rotated again and the state shown in FIG. An opening is formed directly below. That is, when the opening link mechanism 30 is in the state shown in FIG.
(see FIG. 7), and the adhesive applied to the tip allows the bag piece 5 of the umbrella storage bag 50 to come into contact with the umbrella storage bag 50.
Stick to the top edge of 0a. Then, when returning to the state shown in FIG. 1, the other bag piece 50a is pulled. On the other hand, since the other bag piece 50b of the umbrella storage bag 50 is stopped by the stopper 60b, the two bag pieces 50a and 50b are not pulled apart by pulling the bag piece 50a, and an opening is formed. At this time, since there is an air flow from the blowout lower 0b directly below the guide ring 10, both bag pieces 50a
, 50b are attracted to each other by water droplets or static electricity, the opening is not completely and reliably formed, and becomes approximately cylindrical to facilitate insertion of the umbrella (see FIGS. 3 and 7).

When an umbrella is inserted through the guide ring 10 of the automatic umbrella bag storage device that is in the standby state, the guide piece 10e bends and enters the opening of the umbrella storage bag 50, causing the opening of the umbrella storage bag to turn over. is prevented.

Furthermore, after the insertion of the umbrella is detected by the beam sensor 8o, and after a certain period of time has elapsed, that is, after the umbrella has been completely stored, the servo motor 40 is rotated approximately half a turn to reach the state shown in FIG.
The umbrella stored in the umbrella storage bag 50 can be easily pulled out. At this time, the umbrella storage bag SO+ used for storing the umbrella is broken from the perforation 5o and the mounting rod 60a
depart from.

Then, the new umbrella storage bag 50 is equipped with the spring 60c and the biasing plate 6.
0d to come into contact with the stopper 60b.

Thereafter, the new umbrella storage bag 50 is set directly under the guide ring 0 (after passing through the state shown in FIG. 5), and is in the state shown in FIG. 1, waiting.

In addition, in the above explanation, the case where the automatic umbrella bag storage device is installed vertically has been explained, but as is clear from the above description, the automatic umbrella bag storage device of this embodiment has a large problem with respect to its installation location, installation angle, etc. There is a degree of freedom. Therefore, it may be installed at an angle, and in this case there is an effect that the operability such as taking out the umbrella is further improved.

[Effects of the Invention] As explained above, the umbrella storage bag automatic opening device of the present invention (
An adhesive member that adheres to the umbrella storage bag is brought into contact with the opening of the umbrella storage bag, and the adhesive member is moved to form an opening in the umbrella storage bag.

Therefore, a large power source such as a negative pressure source is not required at all, and the opening of the umbrella storage bag can be reliably formed with a small and simple configuration. Furthermore, since a power source is not required to form the opening, reliability, maintainability, and economy are excellent.

Further 1: With the configuration including an airflow creating section that creates an airflow at the position where the opening is formed by the adhesive member, the opening can be completely formed even when the umbrella storage bag is attracted to each other due to water droplets, static electricity, etc. be able to.
