Description

CONNECTION MEMBER OF MOVABLE TYPE CAMP HAVING GOOD DETACHABILITY

TECHNICAL FIELD

The present invention relates to a connection member of

a movable type camp having a good detachability, and more

particularly to a connection member of a movable type camp

having a good detachability in which an insertion hole is formed

at a main pipe and an auxiliary pipe, respectively, when

connecting them, a connection protrusion capable of combining

to the inserting holes simultaneously may be elastically

protruded from the inside of the auxiliary pipe, and inclined

surfaces with a constant angle are formed at the front surface

portion and a side surface portion of the connection protrusion

for assembling/disassembling easily the pipe.

BACKGROUND ART

As is generally well known, various types of a field

barrack or camp have a tent shape structure widely known.

According to the technical gist of the general field barrack

and the camp, they are maintained with a tunnel shape by using a long pole combined with plural poles and have a structure for

preventing the body shape of the field barrack or camp from

modifying by the impact from the outside and simultaneously for

assembling and disassembling the poles easily.

According to the above conventional field barrack or camp,

its entire framework or structure is comprised of only a long

pole as a main pipe and plural poles combined to the long pole,

and cloth is covered on the upper portion of the framework. Since

the plural poles are combined and supported to the long pole,

in general, the long pole and plural poles are combined with

an interference fit method, and the long pole and other poles

are connected with an elastic wire.

However, there is a disadvantage that in the combining

structure of the interference fit method, when the plural poles

are inserted frequently to an inlet portion of the long pole,

the inlet portion is expanded so that the combined pole is

disassembled easily by a weak external force.

In order to solve the foregoing problem, recently a

connection member constructed by at least two or more poles,

as a set, in which its end portion is inserted to the inside of the other pipe is released. In such a connection member, a

connection protrusion with an elastic force is formed at an

external circumference portion of a pipe and a predetermined

penetration hole is formed at an end portion of another pipe,

so that the connection force can be maintained by inserting the

connection protrusion to the penetration hole.

However, according to the above conventional connection

member having the connection protrusion, there are several

disadvantages that since when combining the two pipes, a user

must press the connection protrusion by using one' s own finger,

and when disassembling the pipes, there can be disassembled only

when the user also must press the connection protrusion

protruded through the penetration hole and so the connection

force is removed, the connection member is very inconvenient

in use and in a case that a finger is caught in the penetration

hole when pressing the protruded connection protrusion, a user

may receive a wound.

holes simultaneously may be elastically protruded from the

inside of the auxiliary pipe, and inclined surfaces with a

constant angle are formed at the front surface portion and a

side surface portion of the connection protrusion for

assembling/disassembling easily the pipe.

In order to achieve the above-described object of the

invention, there is provided, in a framework connection

structure of a camp in which the framework is constructed by

a main pipe having a predetermined diameter and openings formed

its both ends, respectively and an auxiliary pipe inserted to

BEST MODE FOR CARRYING OUT THE INVENTION

A connection member of a movable type camp with a good

detachability in accordance with the present invention will now

be described in detail with reference to the accompanying

drawings .

Fig. 1 is a perspective view showing the appearance of a connection member of a movable type camp with a good

detachability in accordance with the present invention and Fig.

2 is an exploded perspective view showing a connection member

of a movable type camp with a good detachability in accordance

with the present invention.

Referring to Figs 1 and 2, a connection member 2 of a

movable type camp with a good detachability in accordance with

an embodiment of the present invention comprises a main pipe

4 forming a framework of a camp and an auxiliary pipe 6 in which

its end is inserted to an end of the main pipe 4. The main pipe

4 is a hollow type and a general pipe in which an opening 8 is

formed at its both ends, respectively, and a penetration hole

4a is formed at its external circumference predetermined

portion.

Also, in the auxiliary pipe 6, the diameter until its

external circumference surface is the same as the diameter until

internal circumference surface, so that an end portion of the

auxiliary pipe can be inserted to the opening 8 of the main pipe

4. A penetration hole 6a is formed at its external circumference

predetermined portion like the main pipe 4. On the other hand, in the present invention, a "_D" shape

of an elastic member 20, which is inserted to the inside of the

auxiliary pipe 6 and generates a constant elastic force toward

the internal circumference surface from the center of the

auxiliary pipe 6 is provided. A lower end of the elastic member

20 is welded to the internal circumference surface of the

auxiliary pipe 6 facing to the penetration hole 6a of the

auxiliary pipe 6.

Also, a connection protrusion 30 inserted through the

penetration holes 4a and 6a formed at the main pipe 4 and the

auxiliary pipe 6 and exposed to the outside is formed at an upper

surface of an upper side end portion of the elastic member 20.

Since the elastic member 20 is fixed to the internal

circumference surface of the auxiliary pipe 6, the connection

protrusion 30 is always exposed through the penetration hole

6a of the auxiliary pipe 6.

Accordingly, when connecting the main pipe 4 and the

auxiliary pipe 6, the connection protrusion 30 exposed through

the penetration hole 6a of the auxiliary pipe 6 is fitted in

the penetration hole 4a formed at the main pipe 4, thereby accomplishing the connection simply. At this time, when moving

the connection protrusion 30 along the internal circumference

surface of the main pipe 4 , the connection protrusion 30 presses

the elastic member 20 and is inserted with a constant length

toward the inside of the pipe, and at such a state, an end portion

10 of the auxiliary pipe 6 can be inserted easily along the inside

circumference surface of the main pipe 4.

Especially, in the connection protrusion 30 provided to

the connection member of a movable type camp with a good

detachability in accordance with the present invention, its

shape is characterized in that when assembling and

disassembling the main pipe 4 and the auxiliary pipe 6, the

assemble and disassemble processes are performed easily.

Detailed explanation about the shape of the connection

protrusion 30 will be described hereinafter with reference to

Figs . 3,4 and 5.

Fig. 3 is a perspective view showing an elastic member

in a connection member of a movable type camp with a good

detachability in accordance with the present invention and Figs .

4a and 4b are views showing an inclined angle of a connection protrusion of an elastic member in a connection member of a

movable type camp with a good detachability in accordance with

the present invention.

Referring to the above drawings, in the connection member

of a movable type camp with a good detachability in accordance

with the present invention, an elastic member 20 is curved with

a "_D" shape and contracted, so that an elastic force is generated.

At this time, according to the curved elastic member 20, when

expanding the elastic, member 20, an expansion force do not

applied exactly toward an upper direction. Accordingly, in

order to connect the connection protrusion 30 easily through

the penetration holes 4a and 6a, an inclined angle with a

predetermined angle , as shown in Fig. 4a, is formed at the

front surface of the connection protrusion 30 by a grinding

process, thereby forming a front surface inclined portion 30a.

Especially, since the front surface inclined portion 30a

of the predetermined angle formed at the front surface portion

of the connection protrusion 30 in accordance with the present

invention is formed toward the connection direction of the main

pipe 4, when inserting and connecting the auxiliary pipe 6 to the main pipe 4, an opening 8 of the main pipe 4 presses to the

front surface inclined portion 30a of the connection protrusion

30, so that the connection protrusion 30 is pressed naturally,

moved downwardly and connected.

Also, preferably, when disassembling the auxiliary pipe

6 from the main pipe 4, in order to disassemble the auxiliary

pipe easily, a left side surface inclined portion 30b with a

predetermined inclined angle β, as shown in Fig. 4b, is formed

at a side surface of the connection protrusion 30 by a grinding

process.

That is , although an inclined surface with a constant angle

may be formed at the rear end surface of the auxiliary pipe in

order to disassemble the auxiliary pipe 6 from the main pipe

4 easily by a grinding process, it is not desirable because,

in such a case, the auxiliary pipe 6 can be disassembled from

the main pipe 4 when a user does not want .

However, in a case that the inclined portion 30b with the

predetermined inclined angle β is formed at the left side of

the auxiliary pipe in accordance with the present invention,

when a user wants to disassemble the auxiliary pipe 6 from the main pipe 4, the user rotates the auxiliary pipe 6 or the main

pipe 4 so that an edge of the penetration hole 4a of the main

pipe 4 can press the connection protrusion 30 along the left

side surface inclined portion 30b of the connection protrusion

30, and the connection protrusion 30 is pressed and disassembled

from the penetration hole 4a. At the state, when the user takes

out the auxiliary pipe 6 from the main pipe 4, the auxiliary

pipe 6 and the main pipe 4 are entirely dissembled.

At this time, in a case that the side surface inclined

portion is formed at both sides, not a side, of the connection

protrusion 30, since the top portion 32 of the connection

protrusion 30 is formed very sharply, the connection protrusion

30 can be detached more easily rather than before, in the present

invention, the inclined portion 30b is formed only at a side

surface (for example, a right or left side surface).

Also, although it is not shown, penetration holes 4a and

6a are formed at the external circumference surface of the

auxiliary pipe 6 and the main pipe 4, respectively, and the

elastic member 20 in which the connection protrusion 30 is

attached at the upper surface thereof is attached to the internal circumference surface of the auxiliary pipe 6.

Thereafter, it is desirable that an elastic wire (not shown) is

inserted through the auxiliary pipe 6 and the main pipe 4 in

order to connect them.

On the other hand, a hooking protrusion (not shown) is

formed at a predetermined portion of the internal circumference

surface of the main pipe 4 in order not to be inserted the

auxiliary pipe 6 with a length beyond a constant length. At a

state that the connection protrusion 30 of the auxiliary pipe

6 is inserted to the penetration hole 4a of the main pipe 4

completely, when the auxiliary pipe 6 is more entered to the

inside of the main pipe 4, since an excessive external force

is applied to the connection protrusion 30 and so the connection

protrusion 30 can be damaged, the hooking protrusion blocks the

entry of the end portion of the auxiliary pipe 6.

In the connection member of a movable type camp with a

good detachability, as constructed above, since the elastic

member 20 in which the connection protrusion 30 is attached at

the upper surface thereof is attached to the internal

circumference surface of the auxiliary pipe 6, when inserting the end portion 10 of the auxiliary pipe 6 to the main pipe 4

through the opening 8 of the main pipe 4 , the opening 8 of the

main pipe 4 presses to the front surface inclined portion 30a

of the connection protrusion 30, so that the connection

protrusion 30 is pressed naturally by the opening 8 of the main

pipe 4 and moved downwardly. At the state, the auxiliary pipe

6 is continually inserted to the inside of the main pipe 4 and

when the connection protrusion 30 is reached to the position

of the penetration hole 4a, the connection protrusion 30 is

protruded and connected at the upper end portion of the

penetration hole 4a by the elastic member 20.

In contrast, when disassembling the auxiliary pipe 6 and

the main pipe 4, a user rotates the auxiliary pipe 6 or the main

pipe 4 so that an edge of the penetration hole 4a of the main

pipe 4 can press the connection protrusion 30 along the left

side surface inclined portion 30b of the connection protrusion

30.

Thereafter, the connection protrusion 30 is pressed by

the side surface circumference portion of the penetration hole

4a, moved downwardly and disassembled from the penetration hole 4a. At the state, when the user takes out the auxiliary pipe

6 from the main pipe 4, the auxiliary pipe 6 and the main pipe

4 are entirely dissembled.

Accordingly, the main pipe 4 and the auxiliary pipe 6 as

a connection member of a movable type camp with a good

detachability in accordance with the present invention make

move the connection protrusion 30 downwardly without contacting

directly with the connection protrusion 30, so the assemble and

disassemble processes are very convenient.

On the other hand, the connection member of a movable type

camp with a good detachability in accordance with the present

invention do not limited above embodiment and can be modified

various types without departing the scope of the technical

concept of the present invention.

INDUSTRIAL APPLICABILITY

As discussed earlier, according to a connection member

of a movable type camp with a good detachability in accordance

with the present invention, in the main pipe and the auxiliary

pipe, an inclined surface portion is formed at the connection direction of the connection protrusion formed at the auxiliary

pipe and an inclined surface portion is also formed at a side

portion of the connection protrusion, so that since the

connection protrusion 30 can be moved downwardly, although a

user do not press the connection protrusion with one's own

finger and the like, there are advantages that the assemble and

dissemble processes are very convenient.
