Description

[Detailed explanation of the invention] This invention relates to an assembly type imitation bridge, which is used for decoration of aquariums for small fish, etc., or for breeding containers for breeding small turtles, crabs, etc. It was designed to allow small turtles and crabs to cross. This prefabricated imitation bridge is composed of a bridge deck and handrail members, and can be used as an imitation bridge by standing up the handrail members at the hinges provided on both edges of the bridge deck. be.

An embodiment of the present invention will be explained below based on the drawings. Figure 1 is a plan view before assembling the imitation bridge,
The figure is a perspective view of the imitation bridge in an assembled state, and 1 is the imitation bridge main body, the bridge deck part 10 and the handrail member 2.
0. The bridge deck part 10 is a rectangular flat plate, and semicircular protrusions 11 are provided at appropriate intervals to give it an undulating shape. Instead of the above-mentioned flat plate, this bridge deck portion 10 may be provided with horizontal rods (not shown) lined up at appropriate intervals. At both ends 12, 12 of the bridge deck portion 10 in the bridge width direction, hinge portions 2 formed thinly and made of resin plastic are successively provided.

A handrail member 20 is formed to extend outwardly flatly with the bridge deck portion 10 via the hinge portion 2, and both ends of the handrail member 20 are extended outward in the length direction of the bridge deck portion 10. It is formed protrudingly. The handrail member 20 is formed by a bridge girder 21 connected to the hinge portion 2, a bundle post 24, and a handrail 22 provided in parallel with the bridge girder 21 via the bundle post 24.

Additionally, main pillars 2 are provided at both ends of the handrail member 20 that is formed to protrude outward in the length direction of the bridge deck portion 10.
3, 23, 23, 23 are formed, and this main pillar 2
On the opposite side of 3, 23, 23, 23 is the imitation bridge body 1
A container 30 for breeding small turtles, crabs, etc. is shown in Figure 4.
Two islands 3 bulging out on the bottom surface 31 of
an engaging protrusion 3 for erection and fixation between 2 and 32;
3, 3, 3 protrude inward from the hinge portion 2 of the bridge deck portion 10, and are formed with their tips facing each other. Note that the main pillar 23 may be provided at an intermediate position of the handrail member 20. Then, the imitation bridge body 1 formed as described above is integrally molded from plastic.

To assemble the imitation bridge main body 1 configured in a flat shape as described above, the imitation bridge main body 1 has a handrail member 2
is made to stand up so that the bridge deck portion 10 and the handrail member 20 are perpendicular to each other (see FIG. 2 of the drawings).
Since the main posts 23, 23, 23, 23 formed at both ends of the handrail member 20 are also vertically erected, the engagement projections formed on the opposing surfaces of the main posts 23, 23, 23, 23 3, 3, 3, 3 are provided at positions projecting downward from the bridge deck portion 10.

In addition, the breeding container 3 for breeding the above-mentioned small turtles, crabs, etc.
Two islands 32, 32 bulging out on the bottom surface 31 of 0
The upper surface is provided with locking holes 33, 33, 33, 33 that engage with the engaging protrusions 3, 3, 3, 3, and the locking holes 33, 33, 33, 33 are provided with the aforementioned locking holes 33, 33, 33, 33. The two islands 3 are formed by fitting the engaging protrusions 3, 3, 3, 3 formed on the main pillars 23, 23, 23, 23.
It is constructed and fixed between islands 2 and 32 to prevent the imitation bridge body 1 from falling from the islands 32 and 32 even if small turtles, crabs, etc. walk on the bridge deck part 10 of the imitation bridge.

As described above, the imitation bridge of the present invention has a handrail member 20
A resin plastic hinge is provided at both ends 12, 12 of the bridge deck portion 10 in the bridge width direction, and is formed to extend outward through the hinge portion 2, and the handrail member thereof is Both end portions of the bridge deck portion 10 are formed to protrude outward in the length direction of the bridge deck portion 10, and main pillars 23, 23, 23, 23 are provided at both ends of the bridge deck portion 10, and the main pillars 23, 23, 23, 23, the engaging protrusions 3, 3, 3, 3 protrude inward from the hinge part 2 of the bridge deck part 10, and their tips are opposed to each other. The imitation bridge made up of a combination of members can be integrally molded into a flat shape and can be assembled extremely easily.

That is, the engaging protrusions 3, 3, 3, 3 are connected to the bridge deck portion 1.
The handrail member 20 protrudes inward from the hinge part 2 of the handrail member 20 and is formed with its tips facing each other.
By standing up, the engaging protrusions 3, 3, 3, 3 can be placed in a position hanging downward from the bridge deck 10 with respect to the bridge deck 10. As a result, the locking holes 33, 3 provided in the two islands of the rearing container 30
3, 33, 33 and the engaging projections 3, 3, 3, 3 can be easily fitted together, and the two islands 32, 32
The imitation bridge of the present invention is securely erected and fixed in between, so that small turtles, crabs, etc. can easily cross over the deck part 10 of the imitation bridge from the upper surfaces of the two islands 32, 32.

Since the present invention has an imitation bridge constructed as described above, the imitation bridge installed in conventional breeding containers is not only used for decoration, but also allows small turtles, crabs, etc. to cross. etc. are two islands 3
It has great utility value as it allows children to go back and forth between 2 and 32 and play freely so that they don't lack exercise.

In addition, since the imitation bridge of the present invention is constructed so that the bridge deck portion 10 and the handrail member 20 can be integrally molded in a flat shape, such an imitation bridge can be easily molded and production costs can be reduced. In addition, since it is in a flat state, it is extremely convenient to pack and transport, and the product itself is extremely unlikely to be damaged during transportation.

Furthermore, the bridge deck part 10 and the handrail member 20 are molded into a flat plate shape with the hinge part 2 made of resin plastic hinges, and the handrail member 20 is erected with the hinge part 2 as a boundary to assemble the imitation bridge. Therefore, bridge deck part 1
Compared to the case where the handrail member 20 and the handrail member 20 are molded separately and assembled with an engagement mechanism, it can be assembled very easily, and even a general consumer can easily assemble it. Moreover, the bridge deck portion 10 and the handrail member 20 are integrated more than the above-mentioned engagement mechanism, and it can be said that the relationship between the two is stronger.
