The convex piece 21 having a stopper for the second plate material is engaged with the groove hole 32 of the third plate material so that it can swing relative to each other in the center, and can be slid relative to each other along the groove hole. When the second plate material and the third plate material are closed with respect to the first plate material, the plates are folded so as to overlap each other, and when the second plate material and the third plate material are opened with respect to the first plate material, a convex piece is formed. By regulating the opening angle as a stopper in the groove hole, a triangular cone shape capable of holding the paper filter is formed. [Selection diagram] Fig. 4

Description

The present invention relates to a dripper that supports a conical paper filter containing ground coffee beans on an extraction container such as a mug.

Conventionally, a dripper generally has a disk-shaped base to be placed on an extraction container and a conical filter accommodating portion having a coffee extraction hole at the bottom, but it is taken to outdoor activities such as camping. Is bulky and inconvenient.

On the other hand, three plate materials having a fitting convex portion and a fitting concave portion are aligned in a triangular pyramid shape, and adjacent plate materials are fitted to each other to accommodate and extract a conical paper filter. A dripper that can be supported on a container has been proposed (see, for example, Patent Document 1). When this dripper is disassembled into three plates and stacked, it becomes thin and easy to store, and it is convenient to carry.

Japanese Patent No. 6089242

However, in the above-mentioned conventional dripper, since the three plate materials are completely separated by disassembly, it may be troubled how to assemble and use these at the time of use, and the two plate materials are fitted to each other. Some tricks are required when assembling the fitting convex portion and the fitting concave portion of the remaining one plate material by fitting the fitting concave portion and the fitting convex portion together. Further, when the three plate materials are separated, there is nothing to be linked to each other, so there is a problem that care must be taken to prevent the individual plate materials from being lost.

In the above patent document, there is an example in which two of the three fitting portions of the plate materials are connected by a hinge, but a hinge and a rivet for fixing the hinge are required, and the number of parts is increased. The number increases, and the cost increases because detailed manual work is required for installation. In addition, the fitting convex part and the fitting concave part are fitted in the remaining one place where the hinge is not used, but since the hinge is cut at that time, the rivet may come off or the hinge may be deformed due to repeated assembly and disassembly. I'm worried.

In view of the above circumstances, the present invention provides a dripper that can easily switch between a folded state and a state of forming a triangular pyramid by engaging three plate members with each other without using a hinge or the like.

The dripper according to claim 1 is
A dripper formed by engaging plate materials formed of three flexible materials, a first plate material, a second plate material, and a third plate material.

According to the dripper according to claim 1, the following excellent effects can be obtained. The three plates are inseparably engaged, and if they are closed to each other as they are, they will be in a folded state, and if they are opened to each other, they will be in a state of forming a substantially triangular pyramid that can hold the paper filter. You don't have to worry about what to do. Further, since the three plate materials are directly engaged with each other by the combination of the convex piece and the concave portion formed on them or the convex slide piece and the groove hole, parts such as a hinge and a rivet for fixing the hinge can be used. It is unnecessary, and the number of parts and assembly man-hours can be reduced to reduce the manufacturing cost. Since the three plates are made of a flexible material, they can be flexed and closed flat and compact, and the opening direction is suggested by the spring force that tries to return to the original, so it is used intuitively. be able to.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The dripper D of the present embodiment is formed by inseparably engaging the first plate material 1, the second plate material 2 and the third plate material 3 shown in FIGS. 1 and 2, and as shown in FIG. The three plates are closed so as to overlap each other and folded into a substantially flat front view, and as shown in FIG. 4, the three plates are opened to each other to hold a paper filter inside. It is possible to switch the usable state of forming a possible approximately triangular pyramid shape. The three plate materials 1 to 3 are made of a thin metal plate having flexibility such as stainless steel and are cut out by a computer-controlled laser cutting machine. In addition, in FIG. 1 and FIG. 2, the inner side surface (the surface in contact with the paper filter in the dripper D formed in the shape of a triangular pyramid) is shown for each plate material.

As shown in FIGS. 1 (a) to 1 (c), the first plate material 1, the second plate material 2, and the third plate material 3 all have an substantially inverted trapezoidal outer shape, and correspond to trapezoidal legs. One of the two left and right sides (left side in the figure) 1a, 2a, 3a is a hypotenuse inclined by about 60 degrees with respect to the upper sides 1b, 2b, and 3b corresponding to the upper bottom of the trapezoid, and the other trapezoid. The other sides (right side in the figure) 1c, 2c, and 3c corresponding to the legs of the trapezoid are trapezoidal sides that are substantially perpendicular to the upper sides 1b, 2b, and 3b. Convex pieces 11, 21 and 31 protruding outward are formed on the hypotenuses 1a, 2a and 3a of each plate material, and each convex piece is after engaging with other plate materials on both sides of its tip. It has claw-shaped protrusions 11a, 21a, 31a to prevent it from coming off. As shown in FIG. 1 (b), the hanging side 2c of the second plate material 2 has a step that projects the upper portion thereof outward, and the hanging side 3c of the third plate material 3 is shown in FIG. 1 (c). As such, it has a step that projects its lower portion outward. These protruding portions serve as operation tabs for opening the second plate material 2 and the third plate material 3.

As shown in FIGS. 1 (a) and 1 (b), the first plate material 1 and the second plate material 2 have concave portions 12 and 22 having substantially inverted triangular holes formed inside the hypotenuses 1c and 2c. The lower hypotenuses 12a and 22a facing the vertical sides 1c and 2c are inclined by about 60 degrees with respect to the upper sides 1b and 2b. Then, as shown by an arrow A in FIG. 2, by inseparably engaging the convex piece 31 of the third plate material 3 with the concave portion 12 of the first plate material 1, the first plate material is centered on the engaging portion. 1 and the third plate material 3 are in a state where they can swing with each other. Further, as shown by an arrow B in FIG. 2, by inseparably engaging the convex piece 11 of the first plate material 1 with the concave portion 22 of the second plate material 2, the first plate material is centered on the engaging portion. 1 and the second plate material 2 can swing with each other. As a result, the second plate material 2 and the third plate material 3 can be opened and closed with respect to the first plate material 1.

Regarding the above, more specifically, the length dimension of the lower hypotenuse 12a of the concave portion 12 of the first plate material 1 is set to be slightly larger than the width dimension of the root of the convex piece 31 of the third plate material 3. As a result, the lower hypotenuse 12a receives the root of the convex piece 31 so that the two can be engaged with each other, and the upper hypotenuse continuous with the lower hypotenuse 12a is provided with a step 12b that functions as a stopper. As a result, the first plate material 1 and the third plate material 3 are inseparable. Further, since the length dimension of the lower hypotenuse 22a of the concave portion 22 of the second plate material 2 is set to be slightly larger than the width dimension of the root of the convex piece 11 of the first plate material 1, the lower hypotenuse 22a is set. The convex piece 11 is accepted so that they can be engaged with each other, and the upper hypotenuse continuous with the lower hypotenuse 22a is provided with a step 22b that functions as a stopper to prevent the convex piece 11 from coming off. The third plate material 3 is inseparable.

As shown in FIG. 1 (c), the third plate material 3 has an arcuate groove 32 that rises upward so as to extend from the inside of the hypotenuse 3a to the inside of the hanging side 3c, and the hanging side is formed. The end 32a facing the 3c is inclined by about 60 degrees with respect to the upper side 3b. Since the groove width dimension of the groove hole 32 is set to be slightly larger than the width dimension of the root of the convex piece 21 of the second plate material 2, as shown by an arrow C in FIG. 2, the groove hole of the third plate material 3 By engaging the convex piece 21 of the second plate material 2 with 32, the convex piece 21 acts as a slide piece that can move in the groove hole, and the second plate material 2 and the third plate material 3 are interlocked with each other. Then, when the convex piece 21 comes into contact with the end portion 32a of the groove hole, it functions as a stopper that limits the movement of the second plate material 2 and the third plate material 3 in the opening direction, and as a result, the second plate material 1 with respect to the first plate material 1. The opening angle of the plate material 2 and the third plate material 3 is regulated. The hypotenuse on which the convex piece is formed, the lower hypotenuse of the concave part that receives the convex piece, and the end of the groove hole are all inclined by about 60 degrees because the dripper D has a triangular pyramid shape. This is to adjust the crossing angle between the plate materials so that

As shown in FIGS. 1 (a) to 1 (c), the lower sides 1d, 2d, and 3d corresponding to the trapezoidal lower bottom of the first plate material 1, the second plate material 2, and the third plate material 3 have vertical sides 1c and 2c. Indentations 13, 23, and 33 formed by cutting inside the plate material are provided near the corners intersecting with 3c. As shown in FIG. 4, when the dripper D is opened and placed on a mug or the like, they engage with the upper edge portion thereof to serve as a fall prevention stopper. Further, the second plate material 2 and the third plate material 3 are provided with holes 24 and 34 for attaching the male member and the female member of the hooks that can be detached from each other in the immediate vicinity of the hanging sides 2c and 3c. This is to hold the hook members 25 (not shown) and 35 attached to the respective holes so as not to open unexpectedly by fitting each other in the folded state as shown in FIG. Is. The upper part protruding outward on the hanging side 2c and the lower part protruding outward on the hanging side 3c are operation tabs as described above, and if the hook is operated with the thumb and index finger as shown in FIG. It helps to easily disengage and open the bond. In addition to the concave portions 12, 22 and groove holes 32 described above, each plate material is provided with a large number of holes, but these are for weight reduction and ensuring the flexibility of each plate material at the time of folding. It is a thing.

The procedure for assembling the foldable and unfoldable dripper D by engaging the plate members 1 to 3 with each other will be described. First, as shown by an arrow B in FIG. 2, the convex piece 11 of the first plate material 1 is engaged with the concave portion 22 from the inner side surface side of the second plate material 2. Specifically, as shown in FIG. 5A, the convex piece 11 and the claw-shaped protrusion 11a are passed from the inner side surface side of the second plate member 2 along the longest side of the concave portion 22, and then convex. The piece 11 is rotated so as to be closer to the lower hypotenuse 22a. The dimensions of the lower end and the upper hypotenuse of the concave portion 22 are set narrower toward the lower hypotenuse 22a, and as shown in FIG. 5 (b), the upper end of the convex piece 11 abuts on the upper hypotenuse. A force is applied as shown by the white arrow to allow the convex piece 11 to pass through the step 22b while bending as shown by the alternate long and short dash line. The convex piece 11 is inseparably engaged with the lower hypotenuse 22a by the claw-shaped protrusion 11a and the step 22b, and the first plate material 1 and the second plate material 2 can swing with each other around the engaging portion.

Next, as shown by an arrow C in FIG. 2, the convex piece 21 of the second plate material 2 is engaged with the groove hole 32 from the inner side surface side of the third plate material 3. However, since the claw-shaped protrusion 21a is caught in the groove hole 32 as it is, the second plate material 2 and the third plate material 3 are inclined to each other. If the convex piece 21 is inserted to the root and then the inclination is eliminated, the claw-shaped protrusion 21a is prevented from coming off and the convex piece 21 does not come off from the groove hole 32. Finally, as shown by an arrow A in FIG. 2, the convex piece 31 of the third plate material 3 is engaged with the concave portion 12 of the first plate material 1. This can be done in the same manner as in the case where the convex piece 11 of the first plate material 1 is engaged with the concave portion 22 of the second plate material 2 (FIG. 5). Although the first plate material 1 and the second plate material 2 and the second plate material 2 and the third plate material 3 are already engaged with each other, there is a certain degree of freedom in the engaging portion between the second plate material 2 and the third plate material 3. Since there is a degree of freedom, it is not particularly difficult to engage the convex piece 31 and the concave portion 12.

By assembling as described above, the plate materials cannot be separated from each other, and the plate materials are folded into a flat shape as shown in FIG. 3 and developed into a triangular pyramid shape as shown in FIG. The dripper D that can be completed is completed. When unfolding from the folded state shown in FIG. 3, when the hook is removed and the third plate material 3 is opened toward the front side in FIG. 3, the convex piece 21 of the second plate material 2 is third in parallel. It slides along the groove 32 of the plate material 3, and the second plate material 2 is opened so as to be pulled toward it accordingly. On the contrary, when folding from the unfolded state shown in FIG. 4, the second plate material 2 is operated by operating the convex piece 21 so as to slide and move in the groove 32 of the third plate material 3. It is closed so as to overlap the inner side surface of the first plate material 1, and at the same time, the third plate material 3 overlaps the outer surface of the second plate material 2 and is closed so as to sandwich the second plate material 2 with the first plate material 1.

By the way, as described above, the engagement between the second plate material 2 and the third plate material 3 originally has a certain degree of freedom, but the first plate material 1 and the second plate material 2, and the first plate material 1 and the third plate material 3 Since they are inseparably engaged with each other, the movable range is limited, and the plate material cannot be separated unless it is deformed or the like. In other words, the three boards are surely maintained in a predetermined connection relationship, so there is no need to worry about what to do when switching between the folded state and the usable unfolded state, and there is no concern about the loss of individual boards. You don't have to use.

Since the three plates are directly engaged by the convex piece and the concave part formed on them, or the combination of the convex piece and the groove hole, there is no need for parts such as a hinge and a rivet for fixing the hinge. The number of parts and assembly man-hours can be reduced to reduce the manufacturing cost. In particular, by forming the three plate materials with a flexible material, the plate material itself can be bent and folded even if the convex piece and the concave portion are directly engaged with each other. Unlike hinges, when folded flat, each plate has a so-called spring force that acts to restore it to its original state. Therefore, if the hooks are disconnected, each plate material tries to return to the original state and becomes a half-opened state, which suggests the opening direction and anyone can intuitively deploy it.
