Description

The present invention relates to an assembly-type foot-operated spraying device that can be installed anywhere, is easy to store or distribute, and is cost-effective.

As a preventive measure against infection, a spray sprayer that sprays a disinfectant solution for disinfecting fingers is used. This type of spray sprayer manually sprays the disinfectant solution in the resin bottle, but there is a hygienic problem because many people have the operated part.

An automatic spray type atomizer that automatically operates the operation part of the spray atomizer when the sensor detects a person's palm and ejects a predetermined amount of sterilizing liquid toward the palm is commercially available. However, the atomizer with a sensor has not been widely used because the operation configuration of the atomizer based on the detection result of the sensor becomes complicated and the cost tends to be high. Therefore, a foot-operated device has been proposed as a spray device for spraying a disinfectant solution onto a spray sprayer without manual operation.

Patent Document 1 discloses a foot stand on which a bottle cradle is fixed so that a spray bottle can be set at a height at which it is easy to disinfect and sterilize fingers. Patent Document 2 discloses a foot-operated disinfectant stand that can change the mounting height position of the holding table to the stand frame and can be used for adults and children with one unit. Patent Document 3 discloses a foot-operated antiseptic solution supply device including a tray on which a plurality of types of bottles having different forms can be placed. Patent Document 4 discloses a foot-operated spraying device that has less burden on the foot, is easy to step on, and does not emit an excessive amount of liquid. Patent Document 5 discloses a hygienic and convenient operating device for a disinfectant spray container, which allows the disinfectant to be sprayed without touching the container.

Each of the devices disclosed in any of the documents has a configuration in which a tray on which a spray sprayer for spraying a disinfectant solution is placed is attached to a predetermined height of the support column, and a foot pedal is provided at the lower part of the support column. Further, a transmission material is provided along the support column to transmit the stress due to the operation of the foot pedal to the pressing mechanism that presses the operation head of the spray sprayer. When the foot pedal is stepped on by the user in such a configuration, the pressing mechanism presses the operation head of the spray sprayer, and the liquid is sprayed from the spray sprayer.

(First Embodiment)
FIG. 1 is a configuration diagram of a foot-operated spraying device according to the present embodiment. As shown in FIG. 1A, the foot-operated spraying device 1 is fixed to a pedestal 11, a cylindrical support column 10 extending substantially vertically upward from the pedestal 11, and substantially parallel to the pedestal 11 on the side portion of the support column 10. A tray 12 is provided. A foot pedal 13 is arranged at the base of the support column 10. A spray sprayer 20 for spraying a liquid such as a sterilizing liquid is placed on the tray 12.

The spray sprayer 20 is a commercially available product provided with a pump member 22 having a nozzle 23 as an operation head at the head of the storage unit 21 in which the liquid is stored. When the pump member 22 is pressed and pushed down, the liquid inside the accommodating portion 21 is sprayed from the nozzle 23.

The foot-operated spray device 1 includes a pressing mechanism 14 for pressing the pump member 22, and a transmission mechanism 15 that transmits stress generated by the operation of the foot pedal 13 to the pressing mechanism 14.
The transmission mechanism 15 is displaceably provided in the cavity of the support column 10, and is displaced by the operation of the foot pedal 13 to displace the pressing mechanism 14 toward the pump member 22. The pump member 22 is pressed by the displacement of the pressing mechanism 14. A cap 16 is attached to the head of the support column 10. The cap 16 is provided with an opening into which the pressing mechanism 14 is inserted. The pressing mechanism 14 is connected to the transmission mechanism 15 in the support column 10 via the cap 16.

The strut 10 is configured by connecting a plurality of sub-struts 101, 102, 103 having the same inner diameter. In this embodiment, an example of the column 10 composed of the three sub columns 101, 102, and 103 will be described, but the number of sub columns can be appropriately determined. As the number of sub-struts increases, the struts 10 can be stored smaller.
The transmission mechanism 15 is composed of the same number of transmission materials as the number of sub-struts. In the present embodiment, the transmission mechanism 15 is composed of three transmission materials 151, 152, and 153.

When the transmission materials 151, 152, and 153 move downward when the foot pedal 13 is stepped on, the pressing mechanism 14 moves downward in conjunction with the movement. The pressing mechanism 14 presses the pump member 22 by moving downward. The liquid is sprayed from the nozzle 23 by pressing the pump member 22.

FIG. 1B shows a state in which the foot-operated spraying device 1 is disassembled. The foot-operated spray device 1 can be disassembled into a pedestal 11, three sub-posts 101, 102, 103, three transmission materials 151, 152, 153, a tray 12, a foot pedal 13, a pressing mechanism 14, and a cap 16. be. By disassembling the foot-operated spraying device 1 into each member, it can be compactly assembled at the time of storage and transportation. Therefore, it is easy to store and transport. At the time of use, these parts are assembled.

The support column 10 of the present embodiment will be described in detail. There are various aspects of the shapes of the sub-posts 101, 102, 103 and how to connect them. Typical embodiments of the sub-posts 101, 102, and 103 are shown in FIGS. 2 (a) to 2 (c). Here, for convenience, an example of one sub-post is shown, but the same embodiment is used for other sub-posts. Further, each sub-post is not limited to a cylinder as long as it is cylindrical, and may be a square cylinder.

One end of the sub-post of FIG. 2A is threaded on the inner diameter, and the other end is threaded on the outer diameter. When connecting the sub-posts, the inner diameter threading of one sub-post and the outer-diameter threading of the other sub-post are screwed together. Since the sub-struts are screwed together, the sub-struts are hard to come off.

One end of the sub-post of FIG. 2B is processed into a concave shape, and the other end is processed into a convex shape. When connecting the sub-posts, the convex portion of the other sub-post is fitted into the concave portion of one sub-post. One end of the sub-post of FIG. 2C is tapered in the inner diameter direction and the other end is tapered in the tip direction. When connecting the sub-posts, the convex portion of the other sub-post is fitted into the concave portion of one sub-post. In the case of the sub-posts of FIGS. 2 (b) and 2 (c), since one sub-post is fitted into the other sub-post, the sub-post can be easily assembled and separated.

A cap 16 is attached to one end of the sub-post 101. The cap 16 is formed with a threaded portion, a concave portion, or a convex portion depending on which shape of FIGS. 2 (a) to 2 (c) the sub-post 101 is formed of. One end of the sub-post 103 is attached to the pedestal 11. Although the details will be described later, the pedestal 11 is provided with a support member into which the sub-post 103 is inserted. The sub-post 103 is attached to the pedestal 11 by inserting one end into the support member, regardless of the shape shown in FIGS. 2 (a) to 2 (c).

FIG. 3 is an explanatory diagram of a connection configuration of the transmission materials 151, 152, and 153 included in the transmission mechanism 15. Each of the transmission materials 151, 152, and 153 has a configuration including a plurality of metal plates having a width less than the inner diameter of the column 10 and a plurality of metal rods having an outer diameter smaller than the inner diameter of the column 10. The transmission materials 151, 152, and 153 are connected to the adjacent transmission materials through the connecting member 154, respectively. Further, the transmission materials 151, 152, and 153 may be configured to include a plurality of metal plates, metal rods, or hard members that relay stress generated by the operation of the foot pedal 13 to adjacent transmission materials.

The connecting member 154 is preferably configured so that it can be easily removed in order to facilitate the connection and separation of the transmission materials 151, 152, and 153. For example, when the transmission materials 151, 152, and 153 are metal plates, openings 155a and 155b are provided at the ends, and the openings 155a and 155b are connected by a connecting member 154. The connecting member 154 is configured to have two protrusions 156a and 156b in a plate-shaped member, one protrusion 156a is inserted into the opening 155a, and the other protrusion 156b is inserted into the opening 155b to form two transmission materials. To concatenate.

In the case of a metal rod or a hard member, the transmission materials 151, 152, and 153 may be connected and separated in the same configuration as the sub-support described with reference to FIG. 2 (a). That is, the transmission materials 151, 152, and 153 are threaded at the ends. In this case, the connecting member 154 becomes unnecessary.

FIG. 4 is an explanatory diagram of a connection portion of the foot pedal 13. The foot pedal 13 includes a hook 131. The hook 131 is attached to the opening 155 of the transmission material 153 provided in the sub-post 103. The sub-post 103 is provided with an opening 1031 for attaching the hook 131 to the transmission material 153. With such a configuration, when the foot pedal 13 is depressed, the transmission material 153 is displaced downward. Due to the downward displacement of the transmission material 153, the transmission materials 152 and 151 are also displaced downward, and the pressing mechanism 14 moves downward. In this way, the stress generated by the operation of the foot pedal 13 is transmitted to the pressing mechanism 14.

Below the transmission material 153, a mounting table 17 on which the transmission material 153 (transmission mechanism 15) is placed and an elastic body 18 are provided in order to support the pressing mechanism 14 at a certain height. By urging the transmission material 153 upward by the elastic body 18, the pressing mechanism 14 is supported on the pump member 22 of the spray sprayer 20.

The transmission mechanism 15 is configured to limit the amount of stepping down operation of the foot pedal 13 to or less than the permissible amount of one push of the spray sprayer 20. Therefore, the spacer 19 is arranged on the pedestal 11 below the mounting table 17.
When the foot pedal 13 is stepped down, the mounting table 17 moves only to the height of the spacer 19. Therefore, the amount of movement of the transmission mechanism 15 can also be restricted from the original height of the mounting table 17 to the height of the spacer 19. This limits the amount of stepping down motion of the foot pedal 13.

FIG. 5 is a configuration example diagram of the pedestal 11. The pedestal 11 may be composed of one flat plate, but in the present embodiment, it is composed of a plurality of metal rods extending radially and a plurality of metal surfaces folded in a fan shape. When the pedestal 11 is composed of a plurality of metal rods or a plurality of metal surfaces, the pedestal 11 can be folded smaller than the case where the pedestal 11 is composed of one flat plate.
Further, the size of the pedestal 11 can be changed according to the installation location of the foot-operated spraying device 1. Therefore, the foot-operated spraying device 1 can be stably installed even in a place where a conventional pedestal cannot sufficiently secure an installation place.

5 (a) to 5 (c) exemplify a pedestal 11 composed of a plurality of metal rods 111a to 111e. FIG. 5A is a view of the pedestal 11 as viewed from the support column 10. FIG. 5B is a perspective view of the pedestal 11. FIG. 5C is a folded view of the pedestal 11.
In the pedestal 11, five metal rods 111a to 111e are radially arranged around the support member 112 into which the sub-post 103 is inserted. The tray 12 is provided above the central metal rod 111c. As a result, even when the spray sprayer 20 is placed on the tray 12, it is possible to prevent the foot-operated spray device 1 from losing its balance and falling over. When storing the pedestal 11, all the metal rods 111 are inverted along the support member 112 as illustrated in FIG. 5 (c). By inverting the metal rod 111, the pedestal 11 can be stored compactly.

5 (d) to 5 (f) illustrate a pedestal 11 composed of a plurality of metal surfaces 113a to 113c. FIG. 5D is a view of the pedestal 11 as viewed from the support column 10. FIG. 5 (e) is a perspective view of the pedestal 11. FIG. 5 (f) is a folded view of the pedestal 11.
In the pedestal 11, three metal surfaces 113a to 113c are arranged in a fan shape around the support member 112. The tray 12 is provided above the central metal surface 113b. As a result, even when the spray sprayer 20 is placed on the tray 12, it is possible to prevent the foot-operated spray device 1 from losing its balance and falling over. When storing the pedestal 11, as illustrated in FIG. 5 (f), all the metal surfaces 113a to 113c are folded in one direction of the support member 112. By folding the metal surface 113, the pedestal 11 can be stored compactly.

FIG. 6 is an exemplary view of the mounting configuration of the tray 12. The tray 12 is composed of a dish portion 120 and a mounting portion 121. A spray sprayer 20 is placed on the dish 120. The mounting portion 121 has an opening 121a into which the sub-post 101 is inserted. The sub-post 101 is provided with a plurality of grooves 1010 at predetermined intervals. A pair of tapered members 122a and 122b are attached to the groove 1010. The pair of tapered members 122a and 122b are positioned by fitting the protruding portions 123a and 123b into the groove 1010, and are fitted and attached to the periphery of the sub-post 101. The tapered members 122a and 122b are configured so that the lower side of the sub-post 101 becomes thicker while being attached to the sub-post 101.

The mounting portion 121 of the tray 12 is fitted into the sub-post 101 from above the sub-post 101. The opening 121a of the mounting portion 121 is larger than the outer diameter on the upper side of the tapered members 122a and 122b, and smaller than the outer diameter on the lower side of the tapered members 122a and 122b mounted on the sub-post 101. Therefore, the opening 121 is fixed below the tapered members 122a and 122b.

In such a configuration, the mounting position of the tray 12 can be made variable according to the position of the groove 1010. By appropriately adjusting the mounting position of the tray 12 according to the size (height) of the spray sprayer 20, the positional relationship between the pump member 22 of the spray sprayer 20 and the pressing mechanism 14 is appropriately maintained.

The tray 12 may be attached to the sub-post 101 without using the tapered members 122a and 122b. For example, the outer diameter of the predetermined portion of the sub-post 101 may be larger than the outer diameter of the other portion, and the mounting portion 121 of the tray 12 may be attached to the predetermined portion. Further, the support column 10 may be formed in a tapered shape having a large outer diameter on the pedestal 11 side so that the tray 12 can be attached.

Further, the sub-posts 102 and 103 may also be provided with a plurality of grooves 1010. In this case, the tray 12 can also be attached to the sub-posts 102 and 103. The spray sprayer 20 mounted on the tray 12 attached to the sub-posts 102 and 103 cannot spray the liquid by the foot pedal 31, but the user can operate the sprayer by his / her own hand to sterilize the liquid. can.

Since the foot-operated spraying device 1 having the above configuration can be folded smaller than the conventional one by making the support column 10 and the transmission mechanism 15 separable, the storage space can be reduced and the transportation becomes easy. .. Further, since the pedestal 11 is composed of the metal rods 111a to 111e and the metal surfaces 113a to 113e, the pedestal 11 can be lightened and folded small. Such a pedestal 11 also reduces the storage space and facilitates transportation.

(Second Embodiment)
FIG. 7 is a block diagram of the foot-operated spraying device of the second embodiment. As shown in FIG. 7A, the foot-operated spraying device 2 is fixed to the pedestal 11, a cylindrical support column 30 extending substantially vertically upward from the pedestal 11, and substantially parallel to the pedestal 11 on the side portion of the support column 30. A tray 12 and a tray 12 are provided. A foot pedal 31 is arranged at the base of the support column 30. A spray sprayer 20 is placed on the tray 12. Since the configurations of the pedestal 11, the tray 12, and the spray sprayer 20 are the same as those in the first embodiment, the description thereof will be omitted. That is, the pedestal 11 has a configuration as illustrated in FIG. 5, and the tray 12 is attached to the support column 30 in a configuration as illustrated in FIG.

The foot-operated spray device 2 includes a pressing mechanism 33 for pressing the pump member 22, and a transmission mechanism 32 for transmitting stress generated by the operation of the foot pedal 31 to the pressing mechanism 33. The transmission mechanism 32 is displaceably provided in the cavity of the support column 30, and the pump member 22 is pressed by the pressing mechanism 33 by being displaced by the operation of the foot pedal 31. The pressing mechanism 33 is supported on the sub-post 301 by the bearing 332 inside the sub-post 301, and rotates around the bearing 332. The pressing mechanism 33 includes a force point portion 331 to which the transmission mechanism 32 is connected, and an action point portion 333 provided with a pressing portion 334 for pressing the pump member 22.

The strut 30 is configured by connecting a plurality of sub-struts 301, 302, 303 having the same inner diameter. The sub-posts 301, 302, and 303 of the second embodiment are square cylinders. In this embodiment, an example of the support column 30 composed of the three sub columns 301, 302, and 303 will be described, but the number of sub columns can be appropriately determined. The connecting portion of the sub-posts 301, 302, and 303 has a configuration in which one sub-post is fitted into the other sub-post, as illustrated in FIGS. 2 (b) and 2 (c).

The transmission mechanism 32 is composed of one wire having a predetermined size. One end of the transmission mechanism 32 is connected to the foot pedal 31, and the other end is connected to the power point portion 331 of the pressing mechanism 33. The sub-post 301 is provided with a pulley 304 for changing the direction in which the transmission mechanism 32 is displaced by the operation of the foot pedal 31 from downward to upward. The transmission mechanism 32 is connected to the power point portion 331 of the pressing mechanism 33 via the pulley 304.

When the transmission mechanism 32 moves downward by stepping on the foot pedal 31, the force point portion 331 of the pressing mechanism 33 moves upward. As a result, the pressing mechanism 33 rotates about the bearing 332, so that the point of action 333 moves downward. As the action point portion 333 moves downward, the pressing portion 334 presses the pump member 22. The liquid is sprayed from the nozzle 23 by pressing the pump member 22.

FIG. 7B shows a state when the foot-operated spray device 2 is folded. In the foot-operated spraying device 2, the pedestal 11 and the tray 12 are removable, and the other parts can be folded together. The sub-posts 301, 302, 303 can be disassembled in the same manner as the sub-posts 101, 102, 103 of the first embodiment, but are not completely separated by the transmission mechanism 32. At the time of folding, the pressing mechanism 33 is taken into the accommodation space 305 provided in the sub-post 301 by the transmission mechanism 32. The foot pedal 31 is taken into the sub-post 303 by the transmission mechanism 32 at the time of folding. Since the support column 30 takes in the pressing mechanism 33 and the foot pedal 31 and is folded, the foot-operated spray device 2 can be compactly assembled during storage and transportation. Therefore, it is easy to store and transport. Further, since the sub-posts 301, 302, and 303 are not completely separated by the transmission mechanism 32, the assembly becomes easy.

FIG. 8 is an explanatory diagram of the pressing mechanism 33. As described above, the pressing mechanism 33 includes a force point portion 331, an action point portion 333, and a pressing portion 334 (FIG. 8A). The power point portion 331 is provided with a connection point 336 to which the transmission mechanism 32 is connected. A hole 335 through which the bearing 332 is inserted is provided between the force point portion 331 and the action point portion 333. The hole 335 is provided at a position where the force point portion 331 is heavier than the action point portion 333 and the pressing portion 334. This is to prevent the pressing portion 334 from accidentally pressing the pump member 22 of the spray sprayer 20 by turning the force point portion 331 downward when the foot pedal 31 is not operating.

The point of action 333 is U-shaped. The pressing portion 334 is connected to a U-shaped open end. The pressing portion 334 is fixed at a position where the pressing surface that comes into contact with the pump member 22 when the pump member 22 is pressed is horizontal when the pressing mechanism 33 is taken out from the accommodation space 305 of the sub-post 301. The pressing portion 334 is accommodated on the same surface as the action point portion 333 in a state where the pressing mechanism 33 is accommodated in the accommodating space 305 of the sub-post 301.

FIG. 8B shows a state in which the pressing mechanism 33 is taken out from the accommodation space 305 of the sub-post 301. FIG. 8C shows a state in which the pressing mechanism 33 is housed in the storage space 305 at the time of storage. As described above, the hole 335 is provided at a position where the force point portion 331 is heavier than the action point portion 333 and the pressing portion 334. Therefore, in the pressing mechanism 33, the sub column 301 is inverted with the sub column 302 facing down. By being accommodated, it is accommodated in the accommodation space 305. At the time of use, the user manually removes the pressing mechanism 33 from the accommodation space 305. At this time, due to the weight of the foot pedal 31, the force point portion 331 does not face downward, and the pressing portion 334 does not accidentally press the pump member 22 of the spray sprayer 20.

FIG. 9 is an explanatory diagram of the foot pedal 31. The foot pedal 31 is connected to the transmission mechanism 32 inside the sub-post 303. Therefore, the foot pedal 31 is a convex shape in which the portion 311 stepped on by the user is formed to be larger than the connection portion 312 to which the transmission mechanism 32 is connected. A connection point 313 is provided in the connection portion 312 for connecting the transmission mechanism 32.

FIG. 10 is an explanatory diagram of the sub-post 303. In FIG. 10, the shape of the sub-post 303 on the pedestal 11 side will be described. The sub-post 303 includes an accommodation space 3031 in which the foot pedal 31 is accommodated during storage, and an insertion space 3032 in which the foot pedal 31 is arranged during use. The connection portion 312 of the foot pedal 31 is inserted into the insertion space 3032 at the time of use and is connected to the transmission mechanism 32 inside the sub-post 303. The accommodation space 3031 is large enough to accommodate the portion 311 stepped on by the user of the foot pedal 31.

FIG. 11 is an explanatory diagram of the sub-post 303 and the foot pedal 31 at the time of use. FIG. 11A is a view seen from the accommodation space 3031 side. FIG. 11B is a perspective view. As shown in the figure, the transmission mechanism 32 has a length such that the foot pedal 31 has a predetermined angle with respect to the pedestal 11. Further, the transmission mechanism 32 has a length that limits the amount of stepping down operation of the foot pedal 31 to or less than the permissible amount of one push of the spray sprayer 20. In order to limit the amount of stepping down operation of the foot pedal 31 to the allowable amount of one push of the spray sprayer 20, a spacer may be provided at the lower part of the foot pedal 31.

FIG. 12 is an explanatory diagram of the sub-post 303 and the foot pedal 31 at the time of folding. FIG. 12A is a view seen from the accommodation space 3031 side. FIG. 12B is a perspective perspective view. The foot pedal 31 is accommodated in the accommodation space 3031 by being pulled into the sub-post 303 by the transmission mechanism 32 at the time of folding. Since the convex shoulder portion of the foot pedal 31 is locked to the upper surface of the accommodation space 3031, the foot pedal 31 is not pulled deep inside the sub-post 303 by the transmission mechanism 32.

In the foot-operated spraying device 2 having such a configuration, the sub-posts 301, 302, and 303 are connected to each other at the time of use, and the transmission mechanism 32 communicates in the cavity. One end of the transmission mechanism 32 is connected to the foot pedal 31, and the other end is connected to the power point portion 331 of the pressing mechanism 33 via the pulley 304. The stress generated by the operation of the foot pedal 31 is transmitted to the power point portion 331 of the pressing mechanism 33 by the transmission mechanism 32. Since the power point portion 331 is rotated upward by the transmission mechanism 32, the action point portion 333 is rotated downward. As the action point portion 333 rotates downward, the pressing portion 334 moves downward. As a result, the pump member 22 is pressed and the liquid is sprayed from the nozzle 23.

During storage, the sub-posts 301, 302, 303 are separated and folded. Since the transmission mechanism 32 is a single wire, the sub-posts 301, 302, and 303 do not come apart. Therefore, the work of reconnecting the sub-posts 301, 302, and 303 is easy. The transmission mechanism 32 pulls the foot pedal 31 into the accommodation space 3031 of the sub-post 303 by separating the sub-posts 301, 302, and 303. Further, in the pressing mechanism 33, the action point portion 333 and the pressing portion 334 are accommodated in the accommodation space 305 of the sub-post 301. Therefore, when the foot-operated spray device 2 is stored, the sub-posts 301, 302, 303, the transmission mechanism 32, the foot pedal 31, and the pressing mechanism 33 are folded into one, as shown in FIG. 7B. As described above, the foot-operated spraying device 2 can be made smaller than the conventional one, so that the storage space can be reduced and the transportation becomes easy.
