RAILING STRUCTURE
Abstract
A railing structure has a railing pipe and at least one
assembling block. The railing pipe is made of aluminum material and
has two assembling face symmetrically adjacent to the two openings.
The assembling block is made of a metal material having a hardness
higher than that of aluminum. The assembling block is formed with a
plate with two perpendicular side boards symmetrically disposed
along two sides, each side board has a groove partially covered by
a positioning tongue, and a free end of the positioning tongue
faces toward the plate, each side board of the assembling block
configured for being placed in a corresponding opening of the
railing tube. The plate completely covers the opening, and the
positioning tongue inserts under the assembling face, thereby
achieving that the assembling block cannot be separated from the
railing pipe in a non-destructive state.

Description
BACKGROUND OF INVENTION
1. Field of Invention
[0001] The present invention relates to a railing structure, and
more particularly to a detachable railing structure with railing
pipes and assembling blocks.
2. Description of Related Art
[0002] Currently, a conventional railing structure comprises a
plurality of cross bars and longitudinal pipes, and the
cross-locking structure of the cross bars and the longitudinal
pipes form a railing structure capable of blocking the passage. The
longitudinal pipe is usually made of a metal material which has the
advantages of sufficient structural strength and low production
cost. Therefore, the two open ends of the conventional longitudinal
tubes are not covered, so foreign matter may fall into the
longitudinal pipes. Furthermore, the sharp opening at both ends
might cause the user being cut accidently. Therefore, the two ends
of the opening are usually additionally provided with a plastic
cover. It is not difficult to find that above-mentioned
conventional structure still has some shortcomings: the plastic
cover is easily pulled by the external force and is separated from
the opening of the longitudinal pipe, which will cause the loss of
the protection effect of the longitudinal pipe and the trouble of
replenishing the plastic cover.
[0003] Therefore, it is desirable to provide a railing structure to
mitigate and/or obviate the aforementioned problems.
SUMMARY OF INVENTION
[0004] An objective of present invention is to provide a railing
structure, which is capable of improving the above-mention
problems.
[0005] In order to achieve the above mentioned objective, a railing
structure has a railing pipe and at least one assembling block. The
railing pipe is made of aluminum material and has two assembling
face symmetrically adjacent to the two openings. The assembling
block is made of a metal material having a hardness higher than
that of aluminum. The assembling block is formed with a plate with
two perpendicular side boards symmetrically disposed along two
sides, each side board has a groove partially covered by a
positioning tongue, and a free end of the positioning tongue faces
toward the plate, each side board of the assembling block
configured for being placed in a corresponding opening of the
railing tube. The plate completely covers the opening, and the
positioning tongue inserts under the assembling face, thereby
achieving that the assembling block cannot be separated from the
railing pipe in a non-destructive state.
[0006] Other objects, advantages, and novel features of invention
will become more apparent from the following detailed description
when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
[0013] First, please refer to FIGS. 1, 2, and 3. A railing
structure comprises a railing tube 10 and at least one assembling
block 20. The railing tube 10 is made from a material comprising
aluminum, two openings 11 at each end have rectangular shapes. Two
assembling faces 12 inside the railing pipe 10 are adjacent to the
openings 11. The at least one assembling block 20 is made of a
metallic material and has a hardness higher than a hardness of
aluminum. The assembling block 20 comprising a plate 21 with two
perpendicular side boards 22 symmetrically disposed along two
sides. Each side board 22 further has a groove 23 partially covered
by a positioning tongue 24, and a free end of the positioning
tongue 24 faces toward the plate 21. Each side board 22 of the
assembling block 20 is configured for being placed in a
corresponding opening 11 of the railing tube 10, such that the
plate 21 completely covers the opening 11 and the positioning
tongue 24 engages with the assembling face 12. Thereby, the
assembly block 20 cannot be separated from the railing pipe 10
easily, and the railing pipe 10 is provided with a plurality of
screws 13 engaging with a plurality of rods 14. The railing pipe 10
is laterally provided with a plurality of the through apertures 15
penetrated by the screws 13, and the railing pipe 10 is provided
with a tapered surface portion 151 on the periphery of the through
aperture 15.
[0014] For actual use, please refer to FIGS. 1-7. The railing pipe
10 is a long tube made of aluminum material, and the two opening 11
of the railing pipe 10 are respectively provided with one
assembling face 12. The assembling block 20 is made of a metal
material having a hardness higher than that of the aluminum
material, an alloy material such as steel or iron. The assembling
block 20 is mounted on the opening 11 of the railing pipe 10, and
the plate 21 of the assembling block 20 provides an effective
shielding for the opening 11 with to prevent foreign matter from
falling into the railing pipe 10 and cuts caused by the opening 11.
The screws 13 are placed through the through apertures 15 of the
railing pipes 10, so that a plurality of the railing pipes 10 can
be arranged on the rod 14 at intervals. Furthermore, the side
boards 22 of the assembling block 20 are placed in the opening 11
of the railing pipe 10, so that the positioning tongue 24 is
subjected to be pressed by forward extrusion of the assembling face
12 of the railing pipe 10 to push the side boards 22 into the
railing pipe 10. Also, the cover 21 presses against the opening 11
to provide cover. The positioning tongue 24 presses against the
assembling face 12 entrenches under the assembling face 12 since
material hardness of the assembly block 20 is greater than the
material hardness of the railing pipe 10. Therefore, the rapid
assembly of the railing pipe 10 and the assembling block 20 are
achieved. When the external force is applied to pull on the
assembly block 20, the positioning tongue 24 reaches under the
assembling face 12 even deeper, so that the assembly block 20
cannot be separated from the railing pipe 10 in a non-destructive
manner, which provides advantages of easy combination and improved
combination strength.
[0015] Although the present invention has been explained in
relation to its preferred embodiment, it is to be understood that
many other possible modifications and variations can be made
without departing from the spirit and scope of invention as
hereinafter claimed.
