An object of the present invention is to provide a new insect trap that does not cause discomfort to the user when removing the used insect trap sheet and has excellent maintainability.

In order to solve such a problem, the present invention provides an insect trap having a pair of facing members, a sheet holding portion, and a sheet extrusion portion. The pair of opposing members are arranged to face each other so as to form an internal space. The seat holding portion is provided inside one of the pair of opposing members. The sheet holding portion has a shape that can be engaged with the edge portion of the insect catching sheet arranged on the inner surface of one of the opposing members, and holds the insect catching sheet. The sheet extrusion portion is provided on a part of one of the opposing members in position corresponding to the insect catching sheet. The sheet extruding portion comes into contact with the insect catching sheet held by the sheet holding portion due to the partial displacement of one of the opposing members due to the external force, and pushes out the insect catching sheet.

Here, in the present invention, the sheet extrusion portion may have a slit that penetrates the front and back surfaces of one of the flexible facing members. In this case, the insect trapping sheet is extruded by elastically deforming the portion of one of the opposing members divided by the slit. Further, instead of this, the sheet extrusion portion may have an opening / closing portion and an urging portion. The opening / closing portion is attached to an opening that penetrates the front and back of one of the opposing members so as to be openable / closable. The urging portion urges the opening / closing portion in the closing direction that closes the opening. In this case, the insect catching sheet is pushed out by displacementing the opening / closing portion in the opening direction in which the opening is opened against the urging force of the urging portion.

In the present invention, a sheet take-out portion may be provided. This sheet take-out portion is provided on the side portion between the pair of facing members, and is provided for taking out the insect catching sheet extruded by the sheet extrusion portion to the outside.

In the present invention, the one facing member may have a three-dimensional inner surface shape that bends the rectangular insect trapping sheet held by the sheet holding portion in a concave shape along the diagonal line thereof. In this case, it is preferable that the sheet extrusion portions are arranged in pairs so as to be symmetrical with respect to the diagonal line of the insect catching sheet.

In the present invention, a light emitting body that is provided inside the other of the pair of opposing members and emits light that attracts insects may be further provided.

According to the present invention, by providing a sheet extrusion portion on one of the opposing members and displacing this portion by an external force, it is possible to extrude the used insect catching sheet without visually observing it. As a result, the chances of insects caught on the used insect catching sheet getting into the eyes are reduced, and the chances of touching the used insect catching sheet are also reduced, so that it is possible to effectively reduce the discomfort to the user. At the same time, since the insect trap sheet held by the sheet holding portion can be pushed out with one touch without disassembling the insect trap, maintainability can be improved.

1 and 2 are external perspective views of the insect trap according to the present embodiment, FIG. 1 shows a non-self-supporting state, and FIG. 2 shows a self-supporting state. The insect trap 1 is installed in a living space, a restaurant, or the like, emits an attracting light having a characteristic of attracting insects, and is attracted by the attracting light to catch insects that have invaded the internal space of the insect trap 1. The housing of the insect trap 1 is mainly composed of a plurality of members arranged in the front-rear direction, specifically, the base member 2 and the roof member 3, and the insect trap 1 realizes additional functions such as independence. A stand member 4 is provided for this purpose. In the present embodiment, the base member 2 and the roof member 3 correspond to a pair of opposing members arranged to face each other in order to form an internal space of the insect trap 1.

The base member 2 and the roof member 3 are fixed in a detachable manner by the magnetic attraction generated between the permanent magnet and the iron. Further, a plurality of openings 10 having different orientations are provided on the side portion of the insect trap 1 formed between the base member 2 and the roof member 3. These openings 10 function as a light emitting portion that emits attracting light to the outside, and also allows insects attracted by the attracting light to invade the internal space of the insect trap 1. Also works as. Further, at least one of the plurality of openings 10 may also function as a sheet taking-out portion for taking out the insect trap sheet housed in the insect trap 1 to the outside.

The appealing feature of the insect trap 1 is, firstly, a three-dimensional shape in which the roof member 3 is inclined in order to harmonize with the installation environment while suppressing the volume (feeling of volume) in the height direction of the housing. At the same time, by suppressing the height of the two corners, the appearance was made lighter. Secondly, by attaching a permanent magnet to the back of the housing, the installation work is simplified and it is possible to support various installation forms such as self-supporting and hooking.

Thirdly, it is equipped with a mechanism that allows the insect trap sheet housed inside the housing to be replaced, and has adopted a structure that is easy to handle even for users who dislike insects and has excellent maintainability. Fourth, the roof member 3 covers the internal space of the insect trap 1 as much as possible so as not to show the unpleasant insects caught by the insect trap sheet, and the plurality of openings 10 ensure sufficient insect trapping performance. Is. Finally, a light source in which a UV LED that emits light that attracts insects and a white LED are mixed is used. As a result, it becomes difficult for the human eye to see the blue attracting light (UV light), and it is possible to give the user the impression that the insect trap 1 is an indirect lighting device.

FIG. 3 is a developed perspective view of the insect trap 1. The insect trap 1 has a base member 2, a roof member 3, a stand member 4, and an optical unit 5, and an insect trap sheet is provided in an internal space formed between the base member 2 and the stand member 3. 6 is detachably housed.

The base member 2 is integrally formed by injection molding using ASA resin or the like, and forms a part of the housing of the insect trap 1. In the present embodiment, as the base member 2, a member having a substantially rectangular shape and having a nearly planar structure is used. Inside the base member 2 (front side in the figure), at least, a light emitting unit 5 having a built-in light emitting body that emits attractive light is provided. Specifically, the central portion 2a located substantially in the center of the base member 2 is recessed in a circular shape with respect to the periphery, and the cylindrical light emitting unit 5 is detachably attached to the depressed central portion 2a. Be done. As a result, the light emitting unit 5 can be effectively hidden when looking into the internal space of the insect trap 1 from the outside. Further, recesses 2b for attaching the roof member 3 are provided at each of the plurality of corners on the front surface of the base member 2. One of a permanent magnet and iron (for example, a permanent magnet) is attached to the recess 2b.

FIG. 4 is a developed perspective view of the light emitting unit 5. The light emitting unit 5 includes a tubular portion 5aa, and light is emitted toward the surroundings from an annular light source 6b attached to the outer surface of the tubular portion 5a. The outer surface of the tubular portion 5a is formed flat, and an uneven heat sink 11d that dissipates heat generated by the LEDs 5c and 5d is provided on the inner surface thereof over the entire circumference. Here, in order to improve the heat dissipation of the heat sink 11d, it is preferable that the tubular portion 5a is made of a metal having high heat dissipation such as aluminum. Further, on the back surface side of the tubular portion 5a, a disk portion 5e having a diameter larger than that of the tubular portion 5a is integrally formed.

The annular light source 5b is provided in an annular shape along the periphery (outer surface) of the tubular portion 5a, and emits light toward the periphery. As the annular light source 5b, for example, a flexible substrate having flexibility capable of following the outer surface shape of the tubular portion 5a can be used, and the flexible substrate includes UVLED 5c and white LED 5d, which are two types of light emitters. Are arranged alternately. The UVLED 5c emits an attracting light that has the effect of attracting insects. As the attracting light, for example, ultraviolet rays (UV) having a peak wavelength of about 360 to 370 nm can be used. On the other hand, the white LED 5d emits white light. By using the white LED 5d together, it is possible to give the user the impression of an indirect lighting fixture while emitting attractive light. A power cord 5f is attached to the annular light source 5b, and electric power for causing two types of LEDs 5c and 5d to emit light is supplied from the outside via the power cord 5f. However, the power may be supplied by incorporating the battery in the insect trap 1 itself instead of supplying the power from the outside.

The annular light source 5b is housed inside the case member 5g. The case member 5g is formed of a translucent (including semipermeable) material such as transparent plastic, and covers the annular light source 5b housed therein as a whole. As a result, it is possible to prevent the hand of the user (exchanger or the like) from directly contacting the LEDs 5c and 5d, so that deterioration of the LEDs 5c and 5d and fluctuations in characteristics can be effectively suppressed. At the same time, the insects attracted by the attracting light do not come into direct contact with the LED5c or the like, and the body fluid of the insects does not adhere to the insects, so that dirt on the LED5c or the like can be effectively prevented. The case member 5g may be provided with the ability to diffuse the light, and the light emitted by the LEDs 5c and 5d may be diffused.

When assembling the light emitting unit 5, first, an annular light source 5b wound in a ring shape is attached to the outer circumference of the tubular portion 5a, and then the case member 5g is put on this and integrated with screws. ..

As shown in FIG. 3, a roof member 3 forming a part of the housing of the insect trap 1 is arranged to face each other on the front surface of the base member 2, and the insect trap is formed by the facing

members

2 and 3. The internal space of 1 is formed. The roof member 3 is integrally formed by injection molding using a flexible material having an appropriate elasticity while maintaining its own shape, for example, silicon rubber. The roof member 3 includes a pair of inclined portions that are inclined in a roof shape toward the rear (that is, the base member 2 side) with their diagonal line D as the top. In other words, the roof member 3 has a roof shape in which a substantially rectangular flat plate member is bent along the diagonal line D thereof.

FIG. 5 is a perspective view showing the inner surface shape of the roof member 3. An insect catching sheet 6 having a surface (adhesive surface) for catching insects by adhesive force is detachably attached to the inner surface of the roof member 3. Specifically, on the inside of the roof member 3 (on the side facing the base member 2),
A sheet holding portion 3a having a shape that can be engaged with the edge portion of the insect trap sheet 8, typically a hook shape, is provided. The seat holding portion 3a engages with a predetermined region on the inner surface of the roof member 3, that is, a corner portion of the insect catching sheet 6 arranged on the seat arranging surface 3b. The seat holding portions 3a are provided at least at two diagonal positions among the four corners provided by the seat arranging surface 4a. Further, the inner peripheral surface (seat arrangement surface 3b) of the roof member 3 has a bent inner surface shape defined by the pair of inclined portions (roof shape) described above.

A part of the roof member 3 is provided with at least one sheet extrusion portion 3c corresponding to the insect catching sheet 6 (seat arrangement surface 3b). The sheet extrusion portion 3c is a range of motion in which the roof member 3 is partially displaced due to an external force applied by the user with a finger. In the present embodiment, the sheet extrusion portion 3c is defined by an L-shaped slit 3d that penetrates the front and back surfaces of the roof member 3.

The number of sheet extrusion portions 3c may be one, but in the present embodiment, from the viewpoint of facilitating the removal work of the insect trap sheet 6, the diagonal line of the insect trap sheet 6, that is, the diagonal line D of the roof member 3 They are arranged in pairs so that they are symmetrical with respect to each other.

The plurality of corners on the inner surface of the roof member 3 are provided with convex portions 3e corresponding to the concave portions 2b on the base member 2 side. A permanent magnet and the other side of iron (for example, iron) are attached to the convex portion 3e. When the convex portion 3e faces the concave portion 2b, the roof member 3 is fixed on the base member 2 in a aligned state by the magnetic attraction generated between the permanent magnet and the iron.

With reference to FIG. 3 again, a pair of stand members 4 are attached to the left and right on the back surface of the base member 2. Like the base member 2, these stand members 4 are made of ASA resin or the like and have a symmetrical shape so as not to be easily deformed by themselves. A convex rotating shaft 4a that engages with a concave portion on the base member 2 side is provided above and below each stand member 4, and can be opened and closed within a predetermined movable range. Further, the stand member 4 is provided with a plurality of hook holes 4b at predetermined positions. When the insect trap 1 is used independently, a pair of stand members 4 housed flush with each other on the back surface of the base member 2 are pulled out. As a result, the insect trap 1 becomes independent in a state where it is about to fall diagonally. Further, when the insect trap 1 is used by hooking it on a wall or the like, the hook is inserted into the hook hole 4a while the stand member 4 is housed in the back surface of the base member 2.

6 and 7 are operation explanatory views of the sheet extrusion unit 3c according to the present embodiment. When removing the used insect trapping sheet 6, the user removes the roof member 3 fixed to the base member 2 by a magnetic attraction force from the base member 2, pushes down the sheet extrusion portion 3c with a finger, and uses this external force. , The insect catching sheet 6 engaged with the sheet holding portion 3a is released.

As shown in FIG. 6, when no external force is applied to the sheet extrusion portion 3c, the sheet extrusion portion 3c, which is a portion divided by the slit 3d, is flush with other portions in the roof member 3. As a result, the insect catching sheet 6 arranged on the inner surface of the roof member 3 is held by the sheet holding portion 3a in a state of being bent diagonally. By bending the insect trap sheet 6, it is possible to prevent the insect trap sheet 6 from being deformed (floating) over time due to humidity or the like. At the same time, by bending the insect trap sheet 6 diagonally in a concave shape, the insect trap sheet 6 is positioned recessed with respect to the opening 10 provided on the side of the insect trap 1, so that the insect trap sheet 6 was caught. Insects (insect trap surface) become difficult to see.

As shown in FIG. 7, when the sheet extrusion portion 3c is pushed down with a finger against the elastic force provided by the roof member 3 itself, the sheet extrusion portion 3c is elastically deformed by this external force and is located in the vicinity of the slit 3d. The edge of the sheet extrusion portion 3c that has been used is displaced downward. Then, this edge portion comes into contact with the back surface of the insect catching sheet 6, and the insect catching sheet 6 is pushed downward. As a result, the insect catching sheet 6 that was engaged with the sheet holding portion 3a comes off and falls off. As a result, the user can discard the insects caught on the used insect trap sheet 6 without seeing them.

As described above, when the opening 10 also functions as a sheet taking-out portion, the insect trap sheet 6 that has fallen into the trap 3 can be inserted into the trap 3 without removing the roof member 3 from the base member 2. It may be taken out to the outside through.

As described above, according to the present embodiment, by providing the sheet extrusion portion 3c on the roof member 3 and displacing this portion by an external force, the used insect catching sheet 6 can be easily extruded without visually observing it. Can be done. As a result, the chances of the insects caught on the used insect catching sheet 6 getting into the eyes are reduced, and the chances of touching the used insect catching sheet 6 are also reduced, so that it is possible to effectively reduce the discomfort to the user. At the same time, since the insect trap sheet 6 can be pushed out with one touch without disassembling the insect trap 1, maintainability can be improved.

Further, according to the present embodiment, if the roof member 3 having the function of the sheet extrusion portion 3c is integrally molded, the roof member 3 with the sheet extrusion portion 3c can be realized easily and inexpensively.

Further, according to the present embodiment, by arranging a pair of sheet extrusion portions 3c so as to be symmetrical with respect to the diagonal line of the insect trap sheet 6, the used insect trap sheet 6 can be extruded more easily and reliably. Can be done.

Further, according to the present embodiment, since the roof member 3 is provided with a pair of inclined portions, it is not necessary to block the side portions in a specific direction due to its structure, and openings can be freely arranged on all the side portions. Yes (securing the degree of freedom of placement). Then, by providing an opening on each of the plurality of side portions having different directions, light that attracts insects can be radiated in a wide range toward the outside (expansion of the radiation direction). Further, when the internal space of the insect trap 1 is viewed from the opening, the inner surface of the roof member 3 has an angle that is easy to see and an angle that is difficult to see, but the line of sight is blocked by the inclined portion located in front of the viewer. At such an angle, much of the inner surface of the roof member 3 will be obscured. Further, since the insect catching sheet 6 itself is also bent according to the inner surface shape of the roof member 3, it becomes difficult to see the insects caught by the insect catching sheet 6 even when looking up. As a result, it is possible to achieve both openness in terms of light radiation and closedness in terms of visual recognition.

In the above-described embodiment, an example in which the sheet extrusion portion 3c is realized by integrally molding the flexible roof member 3 has been described. However, the present invention is not limited to this, and may be realized by a mechanical mechanism as shown below as a modification.

8 and 9 are operation explanatory views of the sheet extrusion portion according to the modified example. The sheet extrusion portion 7 is formed separately from the roof member 3, and is attached to the opening 3f provided in the roof member 3. In this modification, the roof member 3 is made of ASA resin or the like like the base member 2 so as not to be easily deformed by itself. The sheet extrusion portion 7 has an opening / closing portion 7a and an urging portion 7b, and is arranged in pairs so as to be symmetrical with respect to the diagonal line of the insect catching sheet 6 for the same reason as in the above-described embodiment. The opening / closing portion 7a is attached to the opening 3f penetrating the front and back of the roof member 3 so as to be openable / closable around the rotation shaft 7c. The urging portion 7b constantly urges the opening / closing portion 7a in the closing direction (the direction in which the opening 3f is closed). As the urging portion 7b, a leaf spring or the like can be used in addition to the coil spring attached to the rotating shaft 7c.

As shown in FIG. 8, when no external force is applied to the sheet extrusion portion 7, the opening / closing portion 7a urged in the closing direction by the urging portion 7b is on the roof member 3 side provided around the opening 3f. Displacement is regulated by the protrusions of the roof member 3 so that they are flush with the roof member 3. As a result, the insect catching sheet 6 arranged on the inner surface of the roof member 3 is held by the sheet holding portion 3a in a state of being bent diagonally.

Next, as shown in FIG. 9, when removing the used insect catching sheet 6, the user pushes down the opening / closing portion 7a with a finger against the urging force of the urging portion 7b. Due to this external force, the opening / closing portion 7a is displaced in the opening direction (the direction in which the opening 3f is opened). As a result, the edge of the opening / closing portion 7a comes into contact with the back surface of the insect catching sheet 6, and the insect catching sheet 6 is pushed downward. As a result, the insect catching sheet 6 that was engaged with the sheet holding portion 3a comes off and falls off.

Further, in the above-described embodiment, an example in which the insect trap sheet 6 is three-dimensionally bent and held by the inner surface shape of the roof member 3 including the modified example has been described, but the present invention is not limited thereto. Instead, the inner surface of the roof member 3 may be flat, and the insect catching sheet 6 may be held flat without being curved. In this case, the roof member 3 (one facing member) is arranged to face the base member 2 (the other facing member) in the same manner as in the above-described embodiment, but is not in the roof shape but in the same manner as the base member 2. , A substantially rectangular shape and a structure close to a plane structure is used.
