BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] This invention relates to a combination structure for a labyrinth, particularly to
one that is convenient to be assembled, disassembled and transported and can be changed
and recombined to form different routes as one pleases, diversified in labyrinth play,
safe in use and able to attain an effect of implying instruction in amusement.
2. Description of the Prior Art
[0002] Generally, a conventional labyrinth structure sets up outdoors for amusement or for
teaching includes several separating plates and firm joint members combined together.
The firm joint members of the conventional labyrinth structure are generally screws
or iron nails, and the routes designed for the conventional labyrinth are fixed, impossible
to be changed at will, and after played for several times, the fixed routes of the
conventional labyrinth have been already memorized by the players and become familiar
to them, thus losing pleasure and challenge of play in the labyrinth and failing to
arouse public interest and in consequence, leaving the labyrinth structure deserted.
Therefore, the labyrinth routes have to be changed frequently for continuously maintaining
novelty of the labyrinth play; nevertheless, detaching the components of the labyrinth
and then reassembling them together to set up a new labyrinth will take much time
and require lots of troubles and in the course of detachment, the separating plates
are apt to be damaged and impossible to be reused, not only wasting materials but
also contaminating the environment as well. Further, the fixed type labyrinth components
are extremely huge in volume, which are not easy to be moved about and will take too
much space in transportation. Furthermore, after being assembled to make a labyrinth,
the separating plates are in a closed condition and hence, the moving directions of
the players in the labyrinth cannot be seen from the outside. Thus, when children
are playing in the labyrinth, parents are unable to know where the children are, and
the children inside the labyrinth may begin to cry because of panic and even worse,
danger may occur to the children.
SUMMARY OF THE INVENTION
[0003] This invention is devised to offer a combination structure for a labyrinth, convenient
in assembly and disassembly, applicable to any site, easy to be detached and recombined
at will to make up a new labyrinth with different routes, diversified in labyrinth
play and safety in use.
[0004] The combination structure for a labyrinth in the present invention includes lots
of labyrinth units combined together to make up various labyrinths with different
routes. Each labyrinth unit is composed of four frame rods, a reinforcing support
bar and a plurality of fixing members. The four frame rods have their ends mutually
and vertically butt jointed to form into a square, and each frame rod has two ends
respectively formed with a connecting end that is lengthwise cut with a recess and
bored with an insert hole and has its wall bored with plural insert holes. The reinforcing
support bar is obliquely set inside the four frame rods and has two ends formed with
connecting ends respectively bored with an insert hole and having two sides respectively
and axially cut with a recess. The fixing members are inserted through the insert
holes of the connecting ends of the four frame rods and in the insert holes of the
connecting ends of the reinforcing support bar for firmly fastening the four frame
rods and the reinforcing support bar together to make up a labyrinth unit.
[0005] Each frame rod of this invention has one connecting end axially cut with a one-half
recess and another connecting end axially cut with a two-thirds recess, while the
reinforcing support bar has two sides of each connecting end respectively and axially
cut with a one-third recess.
[0006] The fixing members of this invention are tightening cords respectively having one
end provided with female threads and another end provided with male threads.
[0007] Two labyrinth units of this invention can be firmly butt jointed together by means
of the fixing members that are inserted in the mutually-aligned insert holes in the
walls of the two frame rods of the labyrinth units.
