Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spacer for mounting an upper cover and the like in a case for breeding and watching creatures, and more specifically, aquatic organisms such as tropical fish, goldfish, jellyfish, shellfish, aquatic insects, hermit crab, crab, turtle and the like. A breeding appreciation case used for breeding and watching various creatures such as waterside organisms, beetles, hornworms, insects such as grasshoppers, reptiles such as snakes, lizards, crocodile children, small animals such as guinea pigs and rodents. In addition, the same type of case can be stacked separately or a top cover can be placed separately with a space at an appropriate interval so that these organisms do not escape from the upper opening, and it can be detachably attached to the upper end corner of the breeding viewing case Can be attached to
The present invention relates to a small-sized spacer used for holding and stacking a lid in an organism breeding and watching case.

[0002]

BACKGROUND ART Aquatic organisms such as tropical fish, goldfish, jellyfish, shellfish, aquatic insects, and waterside organisms such as hermit crabs, crabs, turtles,
When selling creatures such as beetles, beetles, grasshoppers, and other small animals such as snakes, lizards, crocodile children, guinea pigs, and rodents, these organisms are made of transparent glass. Or, it is generally bred in a breeding appreciation case made of a transparent synthetic resin represented by a transparent acrylic resin.

[0003] In this breeding, if the upper part of the breeding appreciation case is open, these creatures escape to the outside, and dust and foreign matter fall into the case, so as to prevent these adverse effects. Generally, the upper opening of the case is covered with an upper lid such as a transparent glass plate or a transparent acrylic plate.

By the way, a conventional breeding appreciation case, especially a glass aquarium, is often formed with a metal edge for placing an upper lid from the upper edge toward the inside. In the case of breeding appreciation made of transparent resin represented by resin, with the development of molding technology and adhesion technology,
The above-mentioned metal frame is not required, the appearance is good, and it is durable and inexpensive. That is, the case for breeding appreciation without the above-mentioned edge has come to appear.

[0005] In such a breeding appreciation case without edges, if the top cover is to be directly put on it, unless the top cover is somewhat larger (wider) than the opening at the top of the case, the breeding appreciation view is required. There is a danger of accidentally dropping it into the case, but such a large top lid not only makes the appearance unsightly, but also becomes an obstacle when the face is brought close to the breeding appreciation case and causes a safety problem. There is a problem from. Moreover, it is important that the case is not limited to the presence or absence of the edge, and if the top cover is put on these cases, the inside of the case becomes airtight, and it becomes impossible to secure the flow of fresh air, which adversely affects the growth of organisms. However, there are problems such as the inside of the case becoming humid or a bad smell being generated, resulting in unsanitary conditions, and the inner wall of the case becoming cloudy and difficult to appreciate. When these breeding appreciation cases are used as a water tank, the intake of a tube for sending air from the air pump into the water tank is closed by the upper lid.

Conventionally, as a countermeasure in such a case, a method has been adopted in which the position of the upper lid is shifted laterally, or one of the lengths of the upper lid is shortened so as not to cover the entire opening of the case. I was

[0007] Recently, spacers for mounting the upper lid corresponding to the above-described breeding appreciation case without edges have come to appear. Specifically, FIGS. 19 and 2
Numeral 0 denotes the spacer 50. As shown in these figures, the spacer 50 is provided with a mounting portion 5 of the upper lid from one side surface of the saddle-shaped engaging portion 50a to the side.
0b protrudingly formed of resin or metal, and as shown in the following FIGS.
The mounting portions 50b are respectively hooked at a plurality of appropriate positions of the upper opening edges 90a so as to face the opening (inside) of the case 90, and the upper lid 80 is mounted on the mounting portions 50b for use. is there.

That is, when the spacer 50 is used, the upper lid 80 which is slightly smaller than the upper opening of the case 90 is used, so that the edge of the upper lid 80 does not protrude from the case 90 as described above. It also improves safety and appearance. Moreover, the case 90
A gap S corresponding to at least the thickness of the latching portion 50s is formed across the four sides between the upper opening edge 90a and the upper lid 80, so that the inside of the case 90 also has some air flow from the outside air. As a result, the supply of oxygen necessary for the growth of organisms can be obtained, and the inside of the case 90 can be substantially prevented from becoming stuffy or odorous.

[0009]

However, the above-described method of displacing the position of the upper lid laterally, or forming the length of one of the upper lids shorter so as not to cover the entire opening of the case, and providing a gap. In this case, unless the top lid is lifted or removed, the creature in the case is always fed from substantially the same position.

That is, for example, when a large number of tropical fish are bred in a single aquarium (case), some large and agile tropical fish always monopolize the food, and evenly feed all the tropical fish. This raises the problem of breeding that it cannot be given.

For example, when breeding a plurality of insects such as beetles and hornworms in a case, if bait such as cucumbers and kuzuri-bushi are placed in one place in the case, the insects are always concentrated here, It is difficult to watch the entire game, and there is a problem that the viewing becomes uneven. In addition, if the above-mentioned gap is large to some extent, there is also a problem that a helmet, a worm, etc. may escape from here.

On the other hand, when the spacer 50 of the prior art is used, a small gap S is formed around the upper lid 80, and thus, it is possible to disperse small baits into the case from the gap S. In this gap S, there is an advantage that beetle insects and hornworms cannot escape. However, there is a problem that the gap S is too narrow and the size of bait to be put in is limited. In addition, the gap S is too narrow for the tube for sending air from the air pump to the case and the inlet of the cord of the electric heater when raising tropical fish, and there is also a problem that the tube and the cord cannot be put in the case. Remains.

Moreover, since this kind of spacer 50 is hung across the opening edge 90a on one side of the upper portion of the case 90, especially when the upper lid 80 is opened and closed,
In addition to the possibility that the spacer 50 slides and falls into the case 90, the mounting portion 50b of the spacer 50
Because the base of the is formed with a single support,
There remains a big problem that the upper lid falls off due to the weight of the upper lid, and the upper lid falls in the case and easily hits breeding organisms.

The inventor of the present invention has studied how to solve such a problem and has repeatedly made prototypes. In the process, the spacer for mounting the upper lid shown in FIGS. 1 and 2 was used. (Hereinafter, abbreviated as the spacer) 40 has been developed.

That is, as shown in each of these figures, the spacer 40 is engaged with a part of two adjacent edges from a corner of the upper end edge of the breeding viewing case.
a is formed in an L-shape in plan view, and a low-stage mounting for mounting the corner of the upper lid 80 by projecting laterally between lower ends of two side surfaces forming the corner of the hooking portion 40a. The portion 40d is formed. In the figure, reference numeral 40e denotes a groove that fits on the upper edge of the breeding appreciation case.

The use of the spacer 40 is shown in FIG.
As shown in FIG. 4, two edges 90 a adjacent to each other from a corner 90 b of the upper end edge 90 a of the breeding viewing case 90,
The upper end edges 90a of the breeding viewing case 90 and the groove 4
0e, and the spacers 40, 40,... Are provided at the upper four corners 90b, 90b,... Of the breeding viewing case 90 as shown in FIG. 5, and as shown in FIG. 6 and FIG. The mounting part 40 of the spacers 40
A transparent acrylic upper lid 80 is placed on d, 40d,..., and the upper lid 80 covers the upper opening 90x of the breeding viewing case 90.

With such a configuration, a small gap S is formed between each of the edges 90a around the upper end of the breeding viewing case 90 and the periphery of the upper lid 80, and the presence of the gap S allows the breeding viewing appreciation. The circulation of the air between the inside of the case 90 and the outside air is ensured, and the bait can be introduced from any position around the inside of the case 90. In addition, since the gap S is small, for example, beetles and hornworms bred in the case 90 do not escape.

The most characteristic point of this spacer 40 is that it can be hooked over a part of two edges 90a, 90a adjacent to each other at right angles from a corner 90b of the breeding viewing case 90. In this manner, when the hook is held in this manner, an extremely stable posture is ensured, and the hooking position does not shift even when an external force is applied.

Further, the placing section 40 on which the upper lid 80 is placed is described.
Since d is integrally and widely formed with the two side surfaces of the L-shaped hooking portion 40a in plan view, the stability when the upper lid 80 is mounted is extremely high, and the strength against the force for pressing downward is also remarkably increased. There is an advantage of being higher.

As described above, the spacer 40 developed by the present inventor has many excellent points, but has not been satisfactory in several points. One of the limitations is that the size of the bait is limited, for example, the width of the gap S formed when using the spacer 40 is still narrow, and for example, it is not possible to chop the cucumber, which is a favorite of beetle insects, into pieces. It is difficult to feed even if the food is small. The two are that the upper lid 80 is
Since it is placed at a slightly lowered position in x, it is extremely difficult to hook and open the upper lid 80 with a fingertip.

By the way, there is another problem with the above-mentioned conventional spacers. For example, when breeding a large number of insects such as beetles and hornworms, breeding a large number of reptiles of a plurality of types, and when selling them at a store, A plurality of breeding appreciation cases will be prepared, but as a measure for effectively using the indoor space, a metal angle has conventionally been assembled like a bookshelf and arranged side by side on this angled shelf.

Originally, even if these insects and reptiles were put in a breeding appreciation case, the overall weight would not be so large. Is preferred in terms of effective indoor use.

However, stacking this case also means closing the opening at the top of the breeding appreciation case, which causes the above-mentioned various problems in which the flow of outside air into the case cannot be ensured, and also raises the problem. You can't even put food in the case.

Against this background, the present inventor has made intensive studies to improve the above-mentioned invention, and as a result, has found that a case for mounting a top cover or the like in a novel breeding and watching case that solves the above-mentioned problems is provided. This led to the development of a spacer.

That is, the present invention is designed so that the upper opening of the breeding viewing case can be covered with an upper lid or a breeding viewing case of the same kind can be separately stacked with a gap provided in a certain height direction. By forming, even in such a state, it is possible to secure the circulation of the outside air and the air between the breeding and viewing case, and as a result, it is possible to improve the growth environment of the living organisms in the case. This gap has a size and a length that can make it easy to feed food to an appropriate place in the case without, for example, insects, reptiles, turtles, frogs, etc. escaping from the case. When using a breeding appreciation case as a tank for tropical fish, for example, a tube for sending air from the air pump into the case through this gap, or an inlet for the power cord of the electric heater The bottom of the stacked cases can be used in place of the upper lid, and in that use, the upper case can be fixed, the upper lid can be safely attached and detached, and there is no displacement. ,
It is durable and easy to use. An object of the present invention is to provide a spacer having such various advantages.

[0026]

Means for Solving the Problems In order to achieve the above-mentioned object, a spacer for mounting an upper cover or the like in a case for breeding and watching an organism of the present invention (hereinafter, abbreviated as a spacer of the present invention) is a tropical fish, a goldfish, At the top edge of the breeding appreciation case used for breeding and watching aquatic organisms such as jellyfish, shellfish, aquatic insects, hermit crabs, crabs, turtles and other aquatic organisms, beetles, hornworms and other insects, reptiles, small animals, etc. A predetermined gap is provided above the breeding appreciation case at the upper part of the hooking part formed so as to hang over the adjacent two corners, and another case of the same kind is stacked or the upper lid is attached. A spacer main body portion for placing is protrudingly formed, and an edge wall for preventing a displaced position of a stacking case or a top lid is higher than the spacer main body on an outer edge at an upper portion of the hanging portion. That it is out formed is characterized in.

The most characteristic feature of the spacer of the present invention is that the upper opening of the breeding appreciation case is provided with a gap in the height direction to some extent, and the upper cover is put on. The present invention is characterized in that a spacer main body is formed so as to protrude upward above a hooking portion that hooks on an upper end edge of the breeding appreciation case so that the housing can be stacked.

As described above, the height of the spacer main body ensures the circulation of the outside air and the air in the breeding appreciation case to improve the growth environment of the living organisms in the case. Insects, reptiles, turtles, frogs, etc. do not escape from inside and have a size and length that make it easy to put food in the appropriate places in the case, and use a breeding viewing case as a tropical fish tank In this case, a tube that feeds air from the air pump into the case through this gap, or a height that can be used as an inlet for the power cord of the electric heater and an inlet for food, that is, depending on the breeding organism, specifically, Although greatly different, for example, it is about 7.5 mm.

Of course, the height indicated by this numerical value is not a numerical value limited in the present invention, and this numerical value varies greatly depending on the size, behavior, characteristics and behavior of the breeding organism. The shape of the spacer body is not particularly limited as long as a stable posture can be ensured at least when the same type of case is separately stacked on the case and when the upper lid is placed on the case. In the prototype of the present inventor, a sufficiently satisfactory posture was obtained when the gap forming portion was formed in a cylindrical shape.

The material of the spacer of the present invention and the thickness of each part are not particularly limited. Specifically, for example, a spacer made of a metal or a synthetic resin is preferable.
In particular, among these, those made of transparent acrylic resin, which are easy to mold, have excellent appearance, are durable and inexpensive, and each part has a thickness of about 2.5 mm, are most suitable.

The spacer of the present invention is a set of four spacers. However, it is also possible to use a set of three spacers in the vicinity of two adjacent edges at the upper end edge of the breeding viewing case. That hangs over the places where the breeding appreciation case is placed, that is, hangs over two edges around the four corners of the upper end edge of the breeding appreciation case. The part is horizontal 90
° orientation.

The hook portion is not necessarily limited, but is made of metal or synthetic resin and is formed to have a required height, for example, about 1 cm, in a rectangular saddle shape in side view. The groove width of the inverted concavity is formed such that the upper edge of the breeding appreciation case fits, that is, the upper edge fits at least in the hook portion and is not excessively wide, for example, about 5 mm. Have been.

The orientation of the two hooks in the direction of 90 ° in the horizontal direction as described above ensures an extremely stable posture at the time of hooking, and furthermore, the hooking position is displaced even when an external force is applied. Because there is no. Note that these two hooking portions may be partially interrupted, or may be bent into an L shape or a substantially L shape in plan view. Even if it is interrupted, it goes without saying that it is of an integral shape connected by another part, for example, an edge wall or a mounting part.

However, when the hook portion is viewed from above in plan view, L
The shape or the substantially L-shape is high in stability, durable, and excellent in reinforcing the edge wall portion and the mounting portion.

The lower end of one of the hooking portions, that is, the side surface facing the opening of the case when hooked on the breeding appreciation case, further projects laterally in the opening direction of the upper end of the case. In the case where the lower mounting portion is formed, the upper lid can be mounted so as to slightly fall into the opening in the case. In other words, depending on the type of the creature to be bred and the environment in which it is raised, by placing an upper lid or the like on the spacer main body as described above, or by placing the upper lid on this mounting portion, as described above, the case and the upper lid etc. The gap between them can be changed.
The upper lid placed on the spacer body and the upper lid placed on the receiver have different sizes (widths), so it is necessary to use an upper lid according to each use. .

The height of the spacer main body may be changed by stacking or covering low-level ones.

[0037]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The purpose and structure of the spacer of the present invention are as described above. Next, the specific structure of the spacer of the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings.

FIG. 8 is a perspective view of the spacer of the present invention, and FIG.
FIG. 2 is a perspective view showing the spacer of the present invention upside down. As shown in each of these figures, the spacer 1 of the present invention
Is formed of a transparent acrylic resin having a thickness of about 2.5 mm at each part, and has an L-shape when viewed in a plan view, and forms a square saddle-shaped hook portion 1a having a height of 1 cm when viewed from a side. In the vicinity of the corner of the upper surface of the hook 1a,
A spacer body 1b having a height of about 7.5 mm protrudes upward, and has an L-shape in plan view, which is slightly higher than the spacer body 1b on the outer edge of the upper part of the latching section 1a. An edge wall 1c is formed.

The above-mentioned spacer 1 is placed in a breeding appreciation case 90.
In use by being attached to the lower part, as shown in FIGS. 10 to 14, one of the hooks 1 a, that is, the lower end of the side surface facing the opening 90 x of the case 90 when the case 90 Further, the upper end opening 90x of the case 90
A mounting portion 1d of a low platform that protrudes to the side that is the direction is formed. In the figure, 1e is formed by a hook 1a,
And it is a groove which can be fitted into the corner 90b of the breeding appreciation case 90.

The spacer 1 of the present invention having such a shape is 35 mm in length and width and 20 m in height.
m, and the width of the groove 1e is 5 mm. This size is an example of the size of the most commonly used spacer 1, and the size of the breeding viewing case 90 and the wall thickness of the wall used. It may be formed in another size corresponding to the above.

As shown in FIGS. 10 and 11, a method of using the spacer 1 of the present invention having such a shape is as follows.
Upper edges 90a, 90a of the case 90 so as to hang over a part of two adjacent edges 90a, 90a.
The groove 1e of the engaging portion 1a of the spacer 1 of the present invention is fitted into each of the four corners 90b, 90b at the upper end of the case 90 as shown in FIG.
Is attached.

There are two ways to cover the upper opening 90x of the case 90 provided with the spacers 1, 1,... As described above.

One of the methods is to place a transparent acrylic resin upper lid 80 on the mounting portions 1d, 1d,... Of the breeding viewing case 90 stacked upward as shown in FIGS. According to this method, the upper lid 80 is placed so as to fit into the upper opening 90x of the case 90.

The upper lid 80 is provided with the placing portions 1d, 1d.
..Opening 90x of case 90 within a range not falling off
Is smaller than the size of the opening 90x. Therefore, a gap S of a certain size is formed between the opening 90x and the upper lid 80. The gap S is formed between the outside air and the inside of the case 90. Air circulation of the case 90 to improve the growth environment of the creatures in the case 90, while preventing the breeding organisms from escaping from the case 90. Food can be put into a desired place in the case 90 from the gap S.

The other one, as shown in FIGS. 15 and 16, is a spacer main body 1b, 1 of a rearing and viewing case 90.
b. A method of placing a transparent acrylic upper lid 80x on the upper lid 80A. According to this method, the upper lid 80A is placed in a state of being floated above the case 90, and the upper edges 90a, 90
0a ..., the height of the spacer body 1b (7.5 m
A gap P having a height (10 mm) is obtained by adding the thickness (2.5 mm) of the upper surface of the hook 1a to the height m). That is, a gap wider than the former gap S can be obtained.

When the latter method is adopted, the circulation of the outside air and the air inside the case 90 is further ensured, and the growth environment of the creatures in the case 90 is further improved.
Insects, reptiles, tortoises, frogs and the like do not escape from the case 90, and it is easier to feed food to appropriate places in the case 90, and it is possible to feed a large amount of food.

When the latter method is adopted, for example, when the case 90 is used as a tank for tropical fish, a tube for feeding air from an air pump into the case through the gap P, and an inlet for a power cord of an electric heater. It can also be.

Independently of which of these two methods is adopted, the spacer 1 of the present invention may be provided with a gap at regular intervals if the breeding appreciation case 90 has the same size. The creatures can be bred and apprehended in a state of being stacked up and down in multiple stages, and various coordinations can be made according to hobbies to improve the appreciation effect.

This is shown in FIGS. 17 and 18. As shown in each of these figures, the four corners of the upper edge of the two breeding viewing cases 90, 90 according to the method of the present invention are described above. (1,1 ..) are provided, and the breeding appreciation case 90 located below is provided with the above-described upper lid (80,
80A, 80x), the edge wall portions (1c, 1c,...) Constituting a part of the spacers 1, 1,.
Into the spacer body (1b, 1b
..) Another breeding viewing case 90 is placed on the breeding viewing case 90, and the other breeding viewing case 90 is stacked on the breeding viewing case 90 with the above-described gap P provided around. It is configured to be able to.

When another breeding appreciation case is to be stacked on the upper breeding appreciation case 90, the above-described method may be repeated many times. In the case of 80A, the upper lid (80, 80A,
80x).

As described above, the breeding appreciation cases 90, 90
In the method of stacking up and down, the bottom 90c of the upper breeding viewing case 90 serves as the upper lid of the lower breeding viewing case 90, so the lower breeding viewing case 90 needs the above-mentioned upper lid. There is no.

The method of stacking the breeding appreciation cases 90, 90 in this manner is particularly suitable for the upper breeding appreciation case 90, in which the case 90 is not used as an aquarium, such as insects such as beetles and hornworms, and reptiles. It is suitable in such a case. That is, when water is put into the breeding appreciation case 90 in the upper stage, the weight becomes considerable. Of course, the spacer 1 of the present invention can withstand such a weight. However, when removing the living things in the lower breeding appreciation case 90 or inserting a new creature, the upper breeding viewing case 90 is used. Must be dropped.

[0053]

As described above, the spacer according to the present invention is configured as described above. When this spacer is used, the upper opening of the breeding viewing case can be opened.
The top lid could be closed with some gaps. As a result of being able to provide a gap in this way,
The air circulation between the inside of the breeding appreciation case and the outside air was ensured, healthy breeding of living things could be achieved, and the environment in the case could be improved.

In addition, it is possible to provide a tube for feeding food from an arbitrary position around the breeding appreciation case, sending air from an air pump into the case, and an inlet for a cord of an electric heater.

Since this gap is not large enough to escape creatures such as beetles, hornworms, reptiles, tortoises, small animals, etc., which are bred in the case, it is easy to manage the breeding and feed the food through the gap. You can do it.

In particular, when the spacer of the present invention is used,
Since the position of the upper lid can be selected from the upper and lower two stages, and this selection is also the selection of the size of the gap, the optimal environment is selected according to the size and nature of the creatures to be bred and appreciated, the breeding environment, etc. I was able to create it.

As the most important effect, the spacers of the present invention can be stacked and viewed in a multi-stage manner with the above-mentioned gap provided in a breeding viewing case of the same size. It was possible to effectively use the inside of the store and the room.

When the spacer of the present invention is mounted on the upper edge of the breeding appreciation case, the spacer is fitted so as to straddle the two edges forming the corners of the upper edge of the case. Because it is stuck in the lock, the stability is extremely excellent, and there is no lateral displacement.

Further, since the upper edge of the outer edge of the spacer of the present invention is formed with an edge wall protruding upward, the placement position of the upper lid and the stacking breeding viewing case does not shift, which is extremely safe.

Further, in the spacer of the present invention, since the low-stage mounting portion on which the upper lid is mounted is integrally supported by the two side surfaces of the hooking portion located at right angles in the horizontal direction, the strength is high. Thus, the mounting surface was widened and the upper lid could be supported in a more stable posture.
