Hereinafter, the droplet scattering prevention device according to a plurality of embodiments of the present invention will be described with reference to the drawings. In the plurality of embodiments, substantially the same constituent parts are designated by the same reference numerals, and the description thereof will be omitted.
(First Embodiment)
The first embodiment of the present invention will be described with reference to FIGS. 1 to 6.

The droplet scattering prevention device of the present invention is shown in FIG.
The droplet scattering prevention device 10 includes a roll case 1, a transparent sheet 2, supports 4, 7, a take-up sheet 9, a frame 11, a first guide member 12, 13, a second guide member 14, a third guide member 15, and a fourth. The guide members 16, 17, the wheels 18, 19, 20, 21, the support members 22, 24, the fifth guide member 27, and the like are provided. The first guide members 12, 13, the second guide member 14, the third guide member 15, the fourth guide members 16, 17, and the fifth guide member 27 are installed in this order in the downward direction of gravity.

The transparent sheet 2 is a sheet that does not allow droplets to pass through, and is multiplely wound around a cylindrical core 3. In the embodiment of FIG. 1, the transparent sheet 2 wound around the core 3 is taken out downward, and the first guide members 12, 13, the second guide member 14, the third guide member 15, and the fourth guide members 16, 17 are taken out downward. It is wound around the second core 25 via the above.
A core rod 5 is inserted into the cylindrical core 3 in the axial direction. The core 3 can rotate around the core rod 5. Both ends of the core rod 5 are supported by bearings 400 and 700 of the support members 4 and 7. The support members 4 and 7 are fixed to the frame 11. The support members 4 and 7 and the core rod 5 correspond to the support tool of claim 1.

As shown in FIGS. 3 and 4, the pair of first guide members 12 and 13 are curved forward in a convex shape, one ends 121 and 131 are connected to the frame 11, and the other ends 123 and 133 are opposed to each other. , The rear surfaces 122 and 132 come into contact with the transparent sheet 2 and guide the transparent sheet 2.
As shown in FIGS. 3 and 5, the second guide member 14 is located in the downward direction of gravity of the pair of first guide members 12 and 13, is curved forward in a convex shape, and one ends 121 and 131 and the frame 11. The other ends 123 and 133 of each other are connected to each other, and the front surface 141 comes into contact with the transparent sheet 2 to guide the transparent sheet 2.
Both ends of the third guide member 15 are connected to the frame 11, and the front surface 151 is in contact with the transparent sheet 2.
One end of the fourth guide members 16 and 17 is connected to the frame 11, and the rear surfaces 161 and 171 are in contact with the transparent sheet 2.

The winding device 9 includes a cylindrical second core 25 for winding the transparent sheet 2, and shafts 23 and 26 fixed to both ends thereof. A bearing that rotatably supports the shafts 23 and 26 is formed at one end of the support members 22 and 24. The other ends of the support members 22 and 24 are fixed to the frame 11.
The shaft 23 is directly connected to the shaft of the electric motor 28.
The switch 31 for turning on / off the electric motor 28 is connected to the electric motor 28 by a cord 32. The switch 31 is attached to the leg 111 of the frame 11 so that the electric motor 28 can be turned on and off by stepping on it.
When the electric motor 28 rotates, the shaft 23 rotates, and the transparent sheet 2 is wound around the cylindrical second core 25. The electric motor 28 stops when the switch 31 is turned off, and winds the transparent sheet 2 around the second core 25 when the switch 31 is turned on.
The rear surface side of the fifth guide member 27 is in contact with the transparent sheet 2 to guide the transparent sheet 2.

This embodiment has a feed mechanism that includes a wick 3 that is rotatable relative to the frame 11 and a second wick 25.
The movable wheels 18, 19, 20, and 21 are rotatably attached to the legs 111 of the frame 11 so as to roll on the floor surface.

According to this embodiment, when the switch 31 is stepped on, the transparent sheet 2 slides from top to bottom, and the transparent sheet 2 wound around the core 3 at the upper part of the droplet scattering prevention device 10 is pulled out, and the transparent sheet 2 at the lower part is pulled out. The electric motor 31 winds the transparent sheet 2 on the second core 25 of the lower winding device 9.
The transparent sheet 2 blocks the passage of droplets between the core 3 and the second core 25. A convex seat surface is formed on the front side between the first guide members 12, 13, the second guide member 14, the third guide member 15, and the fourth guide members 16, 17. Therefore, there is an effect that the droplets emitted from the rear side bounce off the concave surface of the transparent sheet 2 and are difficult to move to the front side.

According to the first embodiment, for example, the droplet scattering prevention device 10 can be used between a doctor and a patient diagnosed by the doctor. The operation in this case will be described.
When the doctor is on the front side of the droplet scattering prevention device 10 and the patient is on the rear side, the transparent sheet 2 is interposed between the doctor and the patient. Therefore, even if the doctor or the patient splashes the droplets, the transparent sheet 2 blocks the passage of the droplets.
Since the transparent sheet 2 has a predetermined width, the doctor and the patient can communicate with each other through dialogue. The doctor can turn his hand from both sides of the transparent sheet 2 to touch the patient side. The droplets emitted from the doctor or the patient are prevented from scattering to the opposite side of the transparent sheet 2.
When the diagnosis of one patient is completed, the switch 31 is turned on, the electric motor 28 is driven, the transparent sheet 2 is moved downward, and the transparent sheet 2 is moved downward by a predetermined distance, and the doctor and the patient The sheet surfaces of the new transparent sheet 2 face each other. With the sheet surface of this new transparent sheet, even if the droplets scattered by the previous doctor and the patient adhere to the sheet surface between the doctor and the patient, the sheet surface is collected and the sheet surface of the new transparent sheet 2 faces each other. Therefore, hygiene is maintained. Therefore, there is an effect that hygiene is maintained by collecting the transparent sheet every time the patient facing the doctor changes from one to the next.
In the present embodiment, the hanging shape of the transparent sheet 2 is made convex toward the doctor by the first guide members 12, 13, the second guide member 14, the third guide member 15, and the fourth guide member 16, 17. Then, for example, since the droplets emitted from the patient side bounce back to the patient side, there is an effect that it is easy to prevent the transparent sheet 2 from being scattered from the side to the doctor side on the front side.
By moving the transparent sheet downward, the new transparent sheet 2 is placed between the doctor and the patient by moving the transparent sheet downward by a predetermined distance each time the patient changes. This keeps hygiene.

In the present embodiment, since the frame 11 has wheels, the frame 11 can be easily moved to another position on the floor surface. Therefore, when the facing position between the doctor and the patient moves, the droplet scattering prevention device 10 can be easily moved, which is convenient for use.
Since the flow of air from one side of the transparent sheet 2 to the other side is blocked, the droplets scattered on one side are prevented from passing through the other side of the transparent sheet 2. This prevents the droplets from scattering.

(Second Embodiment)
A second embodiment of the present invention will be described with reference to FIG.
The second embodiment is an embodiment in which the transparent sheet is manually wound up. In this embodiment, the take-up device does not include an electric motor.
By turning the second core 25 at the bottom, the transparent sheet is moved downward by gravity. By pulling down the transparent sheet 2 in the downward direction of gravity, the transparent sheet 2 wound around the core 3 is moved downward. The moving distance of the transparent sheet 2 can be manually moved downward by an arbitrary distance.
The transparent sheet that has moved downward may be placed on the floor surface, or may be wound up and collected on the second core 25 of the winding device 9.

The other basic configuration of this second embodiment is the same as that of the first embodiment.

(Third Embodiment)
The third embodiment is an example in which the transparent sheet is wound in the anti-gravity direction (in the direction against gravity) by an electric motor (not shown). A core is rotatably provided on an upper frame (not shown) via a support. Wrap a transparent sheet around this core. When the core is rotated by an electric motor, the transparent sheet advances in the antigravity direction, and the transparent sheet wound around the second core rotatably provided on the lower frame via the support is wound around the upper core. Be done.
The other basic configuration of this third embodiment is the same as that of the first embodiment.
In this third embodiment, since the air flow from one side to the other side of the transparent sheet is blocked, the droplets scattered on one side are prevented from passing through the other side of the transparent sheet. This prevents the droplets from scattering.

(Fourth Embodiment)
The fourth embodiment is an example in which a portable battery power source is used as the power source of the electric motor. A battery (not shown) is attached to the frame, for example.

In this case, since the battery power supply is attached to the frame, there is an effect that the handling of the droplet scattering prevention device becomes convenient.

The other basic configuration of this fourth embodiment is the same as that of the first embodiment.

(Fifth Embodiment)
A fifth embodiment of the present invention will be described with reference to FIGS. 8 to 16.

FIG. 8 shows a hanging state of the transparent sheet of the droplet scattering prevention device of the present invention.
The droplet scattering prevention device 10 includes a roll case 40, a transparent sheet 2, hanging tools 42, 43, handles 46, 47, a guide plate 48, and the like.

The roll case 40 is suspended by hanging tools 42, 43 such as a chain suspended from the frame 41. One ends 421 and 431 of the suspenders 42 and 43 are attached to the frame 41, and the other ends 422 and 432 are attached to the roll case 40.
The roll case 40 has a cylindrical shape, and as shown in FIG. 11, an outlet 54 having a main body cut out is formed on the upper surface thereof. The sheet roll 51 can be taken in and out of the roll case 40 via the take-out port 54. FIG. 11 shows a state in which the sheet roll 51 is housed inside the roll case 40.

The transparent sheet 2 is wound around a cylindrical core 53, one end 200 of which is taken out to the outside, and the transparent sheet 2 hangs down by its own weight. The transparent sheet 2 is a transparent material and is a sheet that does not allow droplets to pass through.

The handles 46 and 47 are composed of an inner cylinder portion 74 at the tip and a handle portion 76. The inner cylinder portion 74 fits into the end portion of the cylindrical core 53 inside the roll case 40. One end of the handle 76 can rotate freely.
The cap 44 fits into the outer wall of the end of the roll case 40. Inside the caps 44 and 45, the inner cylinder portion 74 inserts a first washer 71, a spacer 72, and a second washer 73 on the outer periphery thereof. The inner diameters of the washers 71 and 73 are smaller than the outer diameter of the spacer 72. The inner diameter of the first washer 71 is smaller than the outer diameter of the seat roll 51. As a result, the caps 44 and 45 are positioned in the axial direction with respect to the roll case 40.
The handles 46 and 47 are swingably supported by the roll case 40, and the transparent sheet 2 can be lifted inside the roll case 40. The handle portion 76 of the handles 46 and 47 can rotate about the axis with respect to the caps 44 and 45, and the cylindrical core 53 can be lifted to the inner wall surface of the roll case 40 with the caps 44 and 45 as fulcrums. The transparent sheet 2 maintains the wound state around the core 53 due to the weight of the sheet roll 51, and cannot be unwound.
By rotating the handles 46 and 47 clockwise and counterclockwise, the pull-out length of the transparent sheet 2 can be adjusted, and the position of one end 200 can be operated.

The guide plate 48 has mounting portions 64, 65 that fit into the edge portion 540 that forms the outlet 54 of the roll case 4.
The guide plate 48 has a guide surface 66 that guides the transparent sheet 2 pulled out from the sheet roll 51.
The guide plate 48 has a groove portion 62 extending parallel to the axis of the seat roll 51 on the anti-mounting portion side of the guide surface 66. The groove 62 can insert the cutting edge of the cutter 61 when cutting the transparent sheet 2.
Regarding the transparent sheet 2 guided on the guide surface 66, the transparent sheet 2 is cut in a direction orthogonal to the extending direction of the transparent sheet 2 by passing the cutting edge of a cutter (not shown) from the anti-groove side along the recess of the groove 62. Allows the transparent sheet to be cut.

According to the droplet scattering prevention device of the fifth embodiment, when the handles 46 and 47 are turned, the core 53 is rotated in the same direction, and one end of the transparent sheet 2 is taken out. Alternatively, one end of the transparent sheet can be manually pulled out to take out the transparent sheet 2.
When the transparent sheet 2 is further pulled out, one end of the transparent sheet hangs down due to the weight of the taken out transparent sheet 2. At this time, the unwinding of the transparent sheet is prevented by the frictional force between the weight of the core 53 and the inner wall of the roll case 40 due to the weight of the transparent sheet 2 wound around the core.
The hanging transparent sheet 2 is located between people facing each other. This prevents the droplets from scattering from the human mouth.
After use, when the cutting edge of the cutter is inserted into the groove portion 62, the transparent sheet 2 unexpectedly cut by the guide plate 48 is cut. The cut transparent sheet falls by its own weight or is collected.
The remaining transparent sheet 2 that has been cut can be used as a new transparent sheet 2 for blocking splashes in the next step by turning the handles 46 and 47 again or pulling out one end of the transparent sheet 2.
Therefore, the used transparent sheet can be thrown away, and a new transparent sheet can be used in the next stage, so that the sheet device can be used cleanly and safely.
Even if dirt or yellowing adheres to the sheet, the transparent sheet can be disposed of immediately after use, so it is easy to ensure safety and security from the viewpoint of hygiene management, and it is effective in preventing viruses and splash infection.

The usage state of the droplet scattering prevention device will be described with reference to FIG.
The droplet scattering prevention device 10 is installed between the people facing each other. When the droplet scattering prevention device 10 is arranged between the person facing the person, for example, the doctor and the patient diagnosed by the doctor, the doctor puts out the left and right hands from the front to the back from between the transparent sheet 2 and the frame 41. You can touch the patient facing you with the transparent sheet 2 sandwiched between them.

At the same time, the droplets emitted from the mouth of the doctor or the patient are prevented from being scattered to the opposite side of the transparent sheet by the transparent sheet 2.
FIG. 15 shows a state in which the transparent sheet after cutting the transparent sheet of the droplet scattering prevention device does not hang down.

The other basic configuration of the fifth embodiment is the same as that of the first embodiment.

According to the fifth embodiment, the transparent sheet 2 can be easily cut and replaced with a new transparent sheet when necessary, which is effective as a virus countermeasure in terms of safety and hygiene.

(Sixth Embodiment)
The sixth embodiment shows an example in which the weight 81 is attached to the lower end of the transparent sheet.

A weight of a hanger connecting two places at the lower end of the transparent sheet or a weight connecting one side of the lower end of the transparent sheet may be used.
The other basic configuration of the sixth embodiment is the same as that of the fifth embodiment. Substantially the same configurations are designated by the same reference numerals, and the description thereof will be omitted.

(Other embodiments)
For the transparent sheet of the present invention, for example, biaxially stretched polypropylene can be used. The material of the transparent sheet used in the present invention is not limited to the above.
Further, the transparent sheet of the present invention does not have to be wound in the direction of gravity or the direction of antigravity, and may be a device for winding in the horizontal direction. It is also possible to install the take-up device at the top.
The hanging tool for connecting the frame and the transparent sheet may be not only the base material of the chain but also a string or a fixing rod.
