JP5961069B2 - Seat shutter with ambulatory insect entry prevention function - Google Patents

Description

  The present invention relates to a sheet shutter with a walking insect entry preventing function, for example, a sheet shutter with a walking insect entry preventing function that can be applied to food and medicine related facilities and openings of general houses.

  When worms enter food-related facilities, food can be damaged by worms and mixed into the product as a foreign substance, and when worms enter general homes, they can mediate diseases. In order to reduce such a possibility, it is common practice to close the opening of a facility with a sheet shutter such as an insect net (Patent Document 1).

  The sheet shutter for closing the opening is effective for eliminating insects flying in the air. However, worms, spiders, and insects that walk or crawl on the ground (referred to herein as “walking insects”) may enter the interior through the gap between the edge of the opening and the shutter.

  Therefore, there is a known shutter system in which brush portions to which insect repellents are attached are implanted on at least the upper side and the side of the opening so as to come into contact with the end of the sheet material fed out from the storage case above the opening of the facility. (Patent Document 2).

JP2005-140448 JP 2004-156239 A

The thing of patent document 2 had the following problem.
First, there is a problem of what to do with the shielding property between the lower end of the sheet material and the lower side of the opening. If there is no brush part with a repellent on the lower side of the opening, walkable insects can easily enter from there, and if a brush part is provided on the lower side, the brush or trolley for the person who enters and exits the opening This causes inconveniences such as damage to the brush part when it is stepped on by a person.
Second, since the brush portion rubs against the sheet material every time the sheet shutter is opened and closed, the tip portion of the brush portion may be worn down.
Third, since the brush portion is pressed against the sheet material by the elasticity of the base portion, if the elasticity of the base portion is weakened due to aging deterioration, the brush portion may be separated from the sheet material.

  The present applicant has intensively studied various problems in the prior art and repeated trials for a new solution.

  Regarding the inconvenience of providing the brush portion on the lower side of the opening, an attempt was made to provide a brush portion for carrying a repellent on the lower end side of the sheet material instead of the lower side of the opening. However, this method is good while the seat shutter is closed, but there is a problem that when the seat shutter is temporarily opened, the walking insects walk down the lower side of the opening and enter the facility.

  The approach of the flying insect into the opening can be avoided by using, for example, an existing technique (Patent Document 3) such as an air curtain that pushes the insect approaching the opening outward with a wind. However, since the walking insect enters the fixed surface, it can walk against a large wind force, and it is difficult to prevent entry with a normal air curtain.

  Based on these unique circumstances of walking insects, the characteristics required for seat shutters can be summarized as follows: If a drug layer such as a repellent is installed on the floor side, it prevents people or carts from entering or exiting, Since the location where the drug layer is formed may become dirty due to contact with the tire of the carriage, etc., and the performance may not be exhibited, the drug layer needs to be on the side of the sheet material for the sheet shutter. This means that the medicinal effect should be exerted on the edge side of the opening in an open state.

  In order to realize these seemingly conflicting requests, the present applicant carries an insect repellent agent on the side of the sheet material for the sheet shutter, and touches the opening side like a stamp such as a print. I came up with a novel idea of forming a stamp surface that transfers medicinal properties to the lip.

The first object of the present invention is to carry a medicinal layer on a sheet material for a sheet shutter for closing an entrance / exit (opening) of a facility and to release a medicinal component transferred to the floor side of the entrance / exit at the time of closing. It is to propose a sheet shutter provided with a stamp surface configured so as to remain.
The second object of the present means is to propose a sheet shutter provided with a seat seat on the opening side that can carry the medicinal component transferred from the sheet material without absorbing it in the material.

At least one of these is the lower surface of the drug layer. A gap between adjacent belt-shaped overlapping portions 20 is formed in the drug retention chamber R. This drug retention chamber R is more closed to the outside than the space adjacent to the drug layer 18 shown in FIG. 3, so that the concentration of the drug component in the room is high, and therefore the function of preventing the entry of ambulatory insects is large. The drug retention chamber R does not have to be a completely enclosed space. This point will be described later.

The fourth means has third means, and the weight member is made of a flowable material,
The contact end of the sheet material is a single tubular body that is loop-shaped and flexible when viewed from the lateral direction of the sheet material, and a strip-shaped drug is formed at the center in the width direction of the stamp surface, which is the lower surface of the tubular body.

  1 to 5 show a sheet shutter 1 according to a first embodiment of the present invention. In FIG. 1, A is an opening which is an entrance of a facility. In the present specification, the “opening” means an entrance through which insects may enter, and includes, for example, a window.

  In the present embodiment, the sheet shutter 1 includes a sheet receiving seat 2, a sheet storage case 6, and a sheet member 10.

  The seat receiver 2 is formed at the lower edge of the opening A. The seat seat 2 has a function of preventing a drug component of a drug layer 18 described later from permeating. As a result, the drug component remains in the seat seat 2 even after the seat shutter is opened, and the effect of avoiding the entry of ambulatory insects is exhibited. The seat seat 2 in the illustrated example has a flat upper surface.

  In the applicant's trial experiment, even when the stamp surface 16 with the drug layer 18 was pressed against the concrete substrate, an appropriate stamp action could not be obtained. This is interpreted as a chemical component soaked into the concrete substrate, which is a perforated material, and a sufficient amount of medicinal components did not remain on the surface of the substrate. Therefore, the seat seat 2 is formed in a smooth structure with a material that does not have a hole of a size large enough to soak the drug component. The term “smooth” as used in the claims shall not have microscopic holes (holes capable of sucking liquid chemicals or powdery chemicals) comparable to those of concrete materials. Therefore, it should be understood as not excluding those with irregularities on a macroscopic level.

  The seat seat 2 is provided so as to cover the entire lower side of the opening A. The sheet seat 2 in the illustrated example has the metal plate fixed to the lower edge of the opening with a screw (not shown), but when the original material on the lower side of the opening satisfies the condition that the drug component is not sucked, The lower side of the opening itself may be used as a seat seat, and no special member needs to be attached.

  The sheet storage case 6 is fixed to the upper side of the opening A. The sheet storage case 6 incorporates a drum 8 for winding the sheet material therein, and the rotation of the drum 8 feeds the sheet material through the opening 6a on the lower surface of the sheet storage case. Can do. The drum 8 is rotatably provided by a driving device (not shown) or manually.

  The sheet member 10 includes a sheet material 12 and a weight material 22.

The sheet material 12 is Yes wound by fixing the base end portion to the drum 8 is provided so as to be able to feed from the mouth portion 6a of the sheet storage case 6 in the longitudinal direction X _2. A contact end portion 14 that can contact the sheet receiving seat 2 is formed at the front portion of the sheet material 12 over the entire lateral direction. Since the present invention proposes a closing method between the lower end of the sheet material 12 and the lower side of the opening A, in order to draw the shape of the sheet material 12 in an easy-to-understand manner, The side edges of the sheet material 12 are drawn away from the sides. In practice, however, insects can be introduced by providing a closing means (including the brush part of Patent Document 2) for closing the gap between the side of the opening A and the side edge of the sheet material 12. It is desirable to take measures to eliminate it. Further, as is conventionally known, a guide rail that is long in the vertical direction may be formed on the side of the opening A, and the guide rail may be formed so as to guide both end portions of the sheet material 12 so as to be movable up and down.

  The contact end portion 14 has a stamp surface 16 carrying a drug layer 18 on the lower surface side, and the sheet material is such that the medicinal component M can be transferred from the stamp surface 16 to the sheet seat 2. It is wider than the rest of the. The contact end 14 may be a separate member from the remaining portion of the sheet material 12, but in the preferred illustrated example, the front end side of one sheet material is bent back upward in a loop shape, It is formed into a tubular body P by adhesion and fixing to the sheet material portion above the loop. The tubular body P having the stamp surface 16 is preferably deformable along the surface of the seat seat 2, but this characteristic will be described in an embodiment described later for convenience of explanation. In this embodiment, constituent elements essential to the present invention will be described. The inside of the tubular body P is a cavity C for inserting a weight material 22 to be described later.

  In the present embodiment, one band-plate-like drug layer 18 is continuously formed on the lower surface side of the contact end portion 14 over substantially the entire length in the lateral direction of the sheet material 12. “Consecutively formed” means that a structure in which a drug is attached only to the brush bristles of the brush portions arranged in a line as in Patent Document 2 described above is excluded. The drug layer 18 is formed by layering an insect repellent (for example, insecticide, insect repellent). The drug layer 18 has a first effect in which an insect directly touches the drug layer 18 and dies, and a second effect in which the drug layer 18 is pressed against the sheet seat 2 and the chemical component moves to the sheet seat 2. (Stamping action) and the third effect of volatilization of the drug component from the drug layer 18.

  The mechanism for transferring the drug component from the drug layer 18 to the sheet seat 2 is the same as that for applying a drug (chemical solution or the like) from a general application container to the surface to be applied. Liquid, creamy, and powdery drugs adhere to the adherend surface due to their own adhesive force. The area of the lower surface of the drug layer 18 may be designed in accordance with the adhesive force of the drug so that a sufficient amount of drug solution adheres.

  Examples of the drug used for the drug layer 18 include carbamate compounds, pyrethroid compounds, organophosphorus compounds, and isomers, derivatives, and analogs thereof. Moreover, as resin which comprises the resin body containing these chemical | medical agents, it is set as at least 1 sort (s) of a polyacetal resin and a polyamide resin. Further, the effect of combining the drug having an action of dissolving and holding the contained drug in the resin and imparting sustained release is enhanced. Examples of the drug include at least one of a sulfonamide derivative, a sulfonic acid ester derivative, a carboxylic acid amide derivative, and a carboxylic acid ester derivative. It also includes mixing a fibrous inorganic filler to further enhance the sustained release.

  The weight material 22 is inserted into the cavity C of the contact end portion. The weight layer 22 allows the drug layer 18 to be sandwiched between the seat seat 2 and the above-described stamping action. The length of the weight member 22 is set so as to cover the entire length of the contact end portion 14 in the lateral direction. In the illustrated example, the material of the weight member 22 is a rigid rod, but a fluid material may be used as described later.

  The weight member 22 may also serve as a conventionally known guide rod (not shown). As is well known in the art, this guide bar is inserted through a tubular body formed in the lower portion of the sealing material and extends outward from the left and right sides of the sealing material. Then, guide grooves (not shown) are provided vertically on both the left and right sides of the opening A, and both ends of the guide rod are inserted into the guide grooves so as to guide the elevation of the sheet member 10. can do.

  In the above configuration, the sheet member 10 is fed out from the sheet storage case 6 (see FIG. 3), and the contact portion 14 of the sheet material 12 abuts against the sheet receiving seat 2 to close the opening A. In this closed state, since the stamp surface 16 with the drug layer 18 is in the contact position with the seat receiver 2, the walking insect cannot walk on the seat receiver 2 and enter the facility. .

  Further, the drug component M adheres to the surface of the sheet seat 2 when the drug layer 18 contacts the sheet seat 2. Since the drug layer 18 is pressed into contact with the seat seat 2 by the load of the weight member 22, the drug component uniformly adheres over the entire length of the seat seat 2 in the lateral direction.

  When the sheet member 10 is lifted, the contact end portion 14 is separated from the sheet receiving seat 2, and the drug component M of the drug layer 18 is left on the upper surface of the sheet receiving seat 2 (see FIG. 5). As described above, since the seat seat 2 is formed of a material that does not soak the medicine component, the medicine component M left on the seat seat 2 is until the opening A is closed again by the sheet member 10. During this period, it exhibits insect repellent and insecticidal effects.

  In addition, when a volatile chemical | medical solution is used, although the component left in the seat seat 2 will lose | disappear by volatilization eventually, that does not become a hindrance in implementing this invention. This is because, in a general food and medicine facility, the opening A is usually closed except for a short time required for people and objects to enter and exit. Preventing the entry of ambulatory insects even in such a short time is considered to contribute greatly to improving the reliability of products.

  Hereinafter, other embodiments of the present invention will be described. In these descriptions, the description of the same configuration as that of the first embodiment is omitted.

6 to 8 show a second embodiment of the present invention. In the present embodiment, the weight material 22 described above is first formed of a fluid material such as gel or powder, and the contact end 14 of the sheet material 12 is seated on the seat seat 2 ( to the extent that can be extended to the front and rear direction X ₃ in FIG. 7 reference) sheet material 12 is formed of a flexible material. When the sheet material 12 expands in the front and back direction, the fluid material flows into the expanded region in the contact end portion 14. Then, the portions on both sides of the drug layer 18 in the stamp surface 16 are lowered by the weight of the weight material 22 and overlap the sheet seat 2. Both the portions on both sides of the drug layer 18 and the lower surface of the drug layer 18 are portions that extend in a band shape in the lateral direction of the sheet material 12 and overlap the sheet receiving seat 2. Called.

Regarding the formation of the weight material 22 described above with a fluid material, in the illustrated example, the fluid material is disposed in the lateral direction X _{1 of the} sheet material 12 so that the fluid material does not flow out of the cavity C of the contact end portion 14. It may be placed in a thin and thin storage bag 24. The storage bag 24 is formed of a soft material so that the contact end 14 abuts on the seat seat 2 and does not interfere with the front and back of the sheet material 12 along the surface of the seat seat 2. To do. Further, instead of the storage bag, a lid portion (not shown) that prevents the flowable material from flowing out may be fitted in both sides of the contact end portion 14.

  According to the above configuration, when the abutting end portion 14 is seated on the seat seat 2, the belt-like overlapping portions 20 on both sides of the drug layer 18 are lowered to abut on the seat seat 2, thereby FIG. As shown in A), a gap surrounded by the side surface of the drug layer 18, the lower surface of the stamp surface 16, and the surface of the sheet seat 2 is formed between the belt-shaped overlapping portion 20 and the drug layer 18. For example, the gap is less connected to the outside than the space in the vicinity of the drug layer 18 shown in FIG. 3, and the medicinal components released from the drug layer 18 tend to accumulate. Therefore, the gap is referred to as a drug retention chamber R.

  The advantages of forming the drug retention chamber R are as follows. The opening A is a human doorway, and gravel G or the like attached to the back of the shoe may be placed on the seat seat 2 when the human enters or exits (see FIG. 8B). When the drug layer 18 hits the gravel placed on the sheet seat 2, a gap is formed between the drug layer 18 and the sheet seat 2, and this gap can be an entry path for insects of the same size on the gravel. Since pests have resistance to insecticides and may not die immediately even within the medicinal range, it cannot be said that there is no possibility of entering the facility through the approach route. Therefore, in the present embodiment, the drug retention chamber R is provided on both sides of the drug layer 18. Even if the ambulatory insect tries to pass under the sheet member 10 of the present embodiment, the drug retention chamber R outside the drug layer 18, the gap between the drug layer 18 and the sheet seat 2, the drug inside the drug layer 18 Must pass through residence chamber R. Insects are exposed to medicinal ingredients released from the drug layer 18 during that time, and are likely to become immobile before passing.

9 to 11 show a third embodiment of the present invention. In the present embodiment, instead of a single drug layer 18 in the first embodiment, the lateral X plurality of drug layer 18 parallel to the _first sheet member 12 is provided on the stamp face 16.

  In the present embodiment, the lower surfaces of all the drug layers 18 shown in FIG. 10 are the band-shaped polymerized portions 20, and all the gaps between the adjacent drug layers 18 are formed in the drug retention chamber R.

  According to this configuration, even if gravel G is caught between the lower surface of one drug layer 18 and the sheet seat 2 and a gap is formed, the gap between the lower surface of the other drug layer 18 and the sheet seat 2 Since it is shielded by, it can block the invasion of ambulatory insects.

12 to 13 show a fourth embodiment of the present invention. In the present embodiment, the contact end portion 14 is formed of two flexible tubular bodies P ₁ and P ₂ . In the illustrated example, attached to the upper portion of the tubular body P ₁ formed by the procedure disclosed in the first embodiment, by bending the strip-shaped sheet material into a loop, the tubular body P ₂ formed by connecting at both ends tufted do it.

  Sheet-shaped drug layers 18 are respectively formed on the surfaces of the two tubular bodies P facing each other. When the abutting end portion 14 is seated on the seat seat 2, the two tubular bodies P spread flatly in the opposite directions, and the drug layers 18 overlap the sheet seat 2 as the band-shaped overlapping portions 20. Therefore, the area of the stamp surface 16 can be increased.

In the present embodiment, a drug retention chamber R is formed between the _two tubular bodies P ₁ and P ₂ .

  As an embodiment of the present invention, the seat seat 2 can be formed of a low resilience material such as low resilience urethane. By doing so, when the gravel G is sandwiched between the drug layer 18 and the seat seat 2 as shown in FIG. 14, the seat seat portion near the gravel G is locally depressed. In other words, since the medicinal component is transferred to most of the upper surface of the seat seat 2 except for the locally depressed portion, the stamping action can be ensured. When a perforated material is used as the base material for the seat seat, a non-permeable surface layer is preferably formed on the upper surface side of the base material so as not to penetrate the drug component.
