EMBODIMENTS OF THE INVENTION

Next, a 3D (three dimensions) maze is explained as follows as an example, but it should not be regarded as a limitation to the present invention. Please refer to FIG. 1, which illustrates a first embodiment of a 3D maze according to the present invention. The 3D maze 100 includes an external housing body 1 and a layered inner body 2. The layered inner body 2 is located inside the external housing body 1. The external housing body 1 and/or the layered inner body 2 is made of corrugated paper. When being used by a pet, the 3D maze may further include a folding hook body 3 located at the external housing body 1.

Please refer to FIG. 2, which illustrates an exploded view of FIG. 1. The external housing body 1 includes a plurality of joint portions 11a, 11b and 11c adjacent to each other. Each joint portion 11a, 11b and 11c includes a folding portion 111 and a connection portion 112. The folding portion 111 and the connection portion 112 are connected to each other. Each folding portion 111 includes an extending buckle 1111, and each connection portion 112 includes a corresponding buckle hole 1122. The extending buckle 111 of the joint portion 11a is buckled in the buckle hole 1122 of one adjacent joint portion 11b. Similarly, the extending buckle 111 of the joint portion 11b is buckled in the buckle hole 1122 of adjacent portion 11c.

For more reliable buckling, each connection portion 112 further includes a second extending buckle 1112 and a second buckle hole 1121. The second extending buckle 1112 is buckled in the second buckle hole 1121 of adjacent joint portion 11b. The second extending buckle 1112 of the joint portion 11b is buckled in the second buckle hole 1121 of the adjacent joint portion 11c. Therefore, with three same joint portions, users may assemble the external housing body 1 by themselves, and manufacturers may save on molding costs for joint portions with different shapes.

The layered inner body 2 comprises a plane body 23 and a plurality of standing joint portions 24. The plurality of standing joint portions 24 respectively are joggled to the plane body 23.

For design of the entrance/exit of the maze, at least one of the joint portions 11a includes a first entrance/exit 113. Alternatively, each joint portion 11a, 11b and 11c may have a first entrance/exit. The number of entrances/exits may be changed according to different designs. At least one of the standing joint bodies 24 may include a fourth entrance/exit 241. Alternatively, each standing joint body 24 may be disposed with a fourth entrance/exit 241. These entrances/exits are designed for pets to enter the maze and their numbers may be varied in different designs.

In this embodiment, each connection portion 112 is a hexagonal plane, but the present invention is not limited to such configuration. The joint portion 112 may have different shapes under different designs. The layered inner body 2 further includes a second plane body 21 and a plurality of second standing joint bodies 22. The plurality of second standing joint bodies 22 respectively are joggled to the second plane body 21. To correspond to the space of the shape of the external housing body 1, the plurality of second standing joint bodies 22 are located above the plane body 23. The second plane body 21 is smaller than the plane body 23, and the plane body 23 includes a third entrance/exit 231. At least one of the second standing joint bodies 22 includes a second entrance/exit 221. Therefore, a pet may run into the external housing body 1 via the first entrance/exit 113, run above the plane body 23 via the second entrance/exit 221, then run down via the third entrance/exit 231, and then to the fourth entrance/exit 241.

In addition, referring to FIG. 3, the present invention includes a folding hook body 3, which may be hooked at an external housing body 1 of a 3D maze 100. The folding hook body 3 is cut from corrugated paper. The pressure line L1 is a pressing folding trace and the knife suture L2 is made by cutting the corrugated paper without cutting through it completely. After being folded, the folding hook body is shown as FIG. 4. Two ends of the folding hook body 3 may be disposed with a hook ear portion 31 for hooking at the concave portion 115 (as illustrated in FIG. 2). As illustrated in FIG. 3, the folding hook body 3 includes a corrugated paper main body 30, a plurality of knife sutures L2, a plurality of pressure lines L1 and a hook ear portion 31. The corrugated paper main body 30 has a substantial rectangular shape. The plurality of knife sutures L2 are located separately on a side of the corrugated paper main body 30. The plurality of pressure lines L1 are located separately on the other side of the corrugated paper main body 31. The hook ear portion 31 is located at two short sides of the corrugated paper main body 30. With such, a user may fold the corrugated paper main body 30 along the pressure line L1 and the knife suture L2 in different directions such that the hook ear portion 31 is located at the most exterior side (as illustrated in FIG. 4) and the hook ear portion 31 may be hooked at the external housing body 1 (as shown in FIG. 1 and FIG. 2). The rough side with the knife suture L1 faces outwardly.

Please refer to FIG. 5, which illustrates a varied embodiment of a 3D maze 100′. A user may only use the external housing body 1′ for a pet to play. Preferably, the 3D maze 100′ may further include a ball 4 located inside the external housing body 1′. The ball 4 may further include a bell (not shown) inside the ball 4. When a pet enters the external housing body 1′, the pet may chase the ball 4 for fun.

Because the external housing body 1′ usually needs air through-holes A, these air through-holes A may be designed as circular in shape and the cut circular corrugated paper may be further utilized. Please refer to FIG. 6A and FIG. 6B, in which three circular corrugated paper pieces (cut for the through-holes A) are used to form combination units 41, 42 and 43, which under joggling with each other may form the ball 4. With such design, materials are saved and it is better for the environment. Inside the ball 4, it can be designed with a space 40 for placing a bell or other object to be placed therein so as to attract a pet for fun.

Please refer to the 3D maze as a second embodiment illustrated in FIG. 7, which also has an external housing body 1″ and a layered inner body 2″.

As illustrated in FIG. 8, the external housing body 1″ includes a plurality of joint portions 11a″, 11b″, 11c″ and a plurality of buckle units 13″. Each joint portion 11a″, 11b″ and 11c″ has a plurality of connection portions 112″ adjacent to each other. Each connection portion 112″ includes a buckle hole 1121″. Each buckle hole 1121″ corresponds to each buckle unit 13″ such that the plurality of joint portions 11a″, 11b″ and 11c″ are connected to each other. Specifically, the buckle unit 13″ may be buckled in the buckle hole 1121″ of the joint portion 11a″ and the buckle hole 1121″ of the joint portion 11b″. In this embodiment, the plurality of joint portions may be three joint portions of the same shape. A user may easily use the buckle units 13″ to assemble the external housing body 1″.

The layered inner body 2″ of the second embodiment includes a plane body 21″ and a standing joint body 22″. The standing joint body 22″ is joggled to the plane body 21″. The layered inner body 2″ is located inside the external housing body 1″. One of any of the joint portions 11a″, 11b″ or 11c″ may include a first entrance/exit 113″. The standing joint body 22″ includes a plurality of standing plate 25″. At least of the standing plate 25″ includes a second entrance/exit 221″. In this embodiment, each connection portion 112″ is a pentagonal shape, but the present invention is not limited to such configuration. The joint portion 112″ may have different shapes under different designs.

Similar to the first embodiment, the second embodiment may include a ball (not shown) located inside the external housing body 1″. The ball may further include a bell (not shown) located inside the ball.

The major difference between the first embodiment and the second embodiment is the buckling way of the external housing body. In the first embodiment, the folding portion is directly disposed with an extending buckle, which, after being folded, is buckled in a buckle hole of an adjacent joint portion. In the second embodiment, multiple buckle units are used for fixing the joint portions to each other. Although the first embodiment is illustrated having the shape of a hexagon, and the second embodiment is illustrated having the shape of a pentagon, their shapes may be interchanged or otherwise designed with other shapes. Please refer to FIG. 9 and FIG. 10, which show varied embodiments of a 3D maze 100X, which has hexagonal joint portions 112X and triangle shape joint portions 117X with buckle units 13X to connect and fix each other. The layered inner body 2X is the same as the first embodiment of FIG. 1 and is not repeated further.

The folding hook body 3 has an outwardly rough surface of corrugated paper and is very suitable for pets like cats to crawl through (as shown in reference C). In addition, pets often like to run; the first entrance/exit 113 is suitable for a pet to run into, and there are many designs like the second, third, and fourth entrances/exits for a pet to play. In addition, the entrance/exit may have designs of different size and numbers for providing passing or non-passing conditions to make the game more fun. In addition, the embodiments are made of corrugated paper, are convenient for a user to assemble by himself or herself, and are also good for the environment.

The foregoing descriptions of embodiments of the present invention have been presented only for purposes of illustration and description. They are not intended to be exhaustive or to limit the present invention to the forms disclosed. Accordingly, many modifications and variations will be apparent to practitioners skilled in the art.
