- An object of the present invention is to provide 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.
- 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 the main pipe for forming the framework, a connection member of a movable type camp with a good detachability comprising: the main pipe and the auxiliary pipe having a penetration hole at a predetermined portion of its external circumference surface, respectively; an elastic member having a “⊃” shape attached to the inside of the auxiliary pipe so that a constant elastic force is generated toward the inside circumference portion from the center of the auxiliary pipe; and a connection protrusion formed at the top surface of the upper end portion of the elastic member, which is inserted to the penetration holes of the main pipe and the auxiliary pipe and exposed to the outside, whereby the assemble and disassemble processes of the framework are performed easily.
- Preferably, the connection protrusion has a front surface inclined portion formed with a predetermined angle α by a grinding process at its front surface portion, so that when connecting the main pipe and the auxiliary pipe, the opening of the main pipe can press the connection protrusion.
- More preferably, the connection protrusion has a side surface inclined portion formed with a predetermined angle β by a grinding process at its side surface portion, so that when disassembling, when the auxiliary pipe is rotated toward a direction, the penetration hole of the main pipe can press the side surface inclined portion of the connection protrusion.

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 andFIG. 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 , aconnection 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 anauxiliary 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 anopening 8 is formed at its both ends, respectively, and apenetration hole 4 a 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 theopening 8 of the main pipe 4. Apenetration hole 6 a is formed at its external circumference predetermined portion like the main pipe 4. - On the other hand, in the present invention, a “⊃” shape of an
elastic member 20, which is inserted to the inside of theauxiliary pipe 6 and generates a constant elastic force toward the internal circumference surface from the center of theauxiliary pipe 6 is provided. A lower end of theelastic member 20 is welded to the internal circumference surface of theauxiliary pipe 6 facing to thepenetration hole 6 a of theauxiliary pipe 6. - Also, a
connection protrusion 30 inserted through thepenetration holes auxiliary pipe 6 and exposed to the outside is formed at an upper surface of an upper side end portion of theelastic member 2 0. Since theelastic member 20 is fixed to the internal circumference surface of theauxiliary pipe 6, theconnection protrusion 30 is always exposed through thepenetration hole 6 a of theauxiliary pipe 6. - Accordingly, when connecting the main pipe 4 and the
auxiliary pipe 6, theconnection protrusion 30 exposed through thepenetration hole 6 a of theauxiliary pipe 6 is fitted in thepenetration hole 4 a formed at the main pipe 4, thereby accomplishing the connection simply. At this time, when moving theconnection protrusion 30 along the internal circumference surface of the main pipe 4, theconnection protrusion 30 presses theelastic member 20 and is inserted with a constant length toward the inside of the pipe, and at such a state, anend portion 10 of theauxiliary 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 theauxiliary pipe 6, the assemble and disassemble processes are performed easily. Detailed explanation about the shape of theconnection protrusion 30 will be described hereinafter with reference toFIGS. 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 andFIGS. 4 a and 4 b 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 “⊃” shape and contracted, so that an elastic force is generated. At this time, according to the curvedelastic member 20, when expanding theelastic member 20, an expansion force do not applied exactly toward an upper direction. Accordingly, in order to connect theconnection protrusion 30 easily through thepenetration holes FIG. 4 a, is formed at the front surface of theconnection protrusion 30 by a grinding process, thereby forming a front surface inclinedportion 30 a. - Especially, since the front surface inclined
portion 30 a of the predetermined angle α formed at the front surface portion of theconnection protrusion 30 in accordance with the present invention is formed toward the connection direction of the main pipe 4, when inserting and connecting theauxiliary pipe 6 to the main pipe 4, an opening 8 of the main pipe 4 presses to the front surface inclinedportion 30 a of theconnection protrusion 30, so that theconnection 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 inclinedportion 30 b with a predetermined inclined angle β, as shown inFIG. 4 b, is formed at a side surface of theconnection 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, theauxiliary pipe 6 can be disassembled from the main pipe 4 when a user does not want. - However, in a case that the
inclined portion 30 b 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 theauxiliary pipe 6 from the main pipe 4, the user rotates theauxiliary pipe 6 or the main pipe 4 so that an edge of thepenetration hole 4 a of the main pipe 4 can press theconnection protrusion 30 along the left side surface inclinedportion 30 b of theconnection protrusion 30, and theconnection protrusion 30 is pressed and disassembled from thepenetration hole 4 a. At the state, when the user takes out theauxiliary pipe 6 from the main pipe 4, theauxiliary 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 thetop portion 32 of theconnection protrusion 30 is formed very sharply, theconnection protrusion 30 can be detached more easily rather than before, in the present invention, theinclined portion 30 b is formed only at a side surface (for example, a right or left side surface). - Also, although it is not shown,
penetration holes auxiliary pipe 6 and the main pipe 4, respectively, and theelastic member 20 in which theconnection protrusion 30 is attached at the upper surface thereof is attached to the internal circumference surface of theauxiliary pipe 6. Thereafter, it is desirable that an elastic wire (not shown) is inserted through theauxiliary 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 theconnection protrusion 30 of theauxiliary pipe 6 is inserted to thepenetration hole 4 a of the main pipe 4 completely, when theauxiliary pipe 6 is more entered to the inside of the main pipe 4, since an excessive external force is applied to theconnection protrusion 30 and so theconnection protrusion 30 can be damaged, the hooking protrusion blocks the entry of the end portion of theauxiliary 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 theconnection protrusion 30 is attached at the upper surface thereof is attached to the internal circumference surface of theauxiliary pipe 6, when inserting theend portion 10 of theauxiliary pipe 6 to the main pipe 4 through theopening 8 of the main pipe 4, the opening 8 of the main pipe 4 presses to the front surface inclinedportion 30 a of theconnection protrusion 30, so that theconnection protrusion 30 is pressed naturally by the opening 8 of the main pipe 4 and moved downwardly. At the state, theauxiliary pipe 6 is continually inserted to the inside of the main pipe 4 and when theconnection protrusion 30 is reached to the position of thepenetration hole 4 a, theconnection protrusion 30 is protruded and connected at the upper end portion of thepenetration hole 4 a by theelastic member 20. - In contrast, when disassembling the
auxiliary pipe 6 and the main pipe 4, a user rotates theauxiliary pipe 6 or the main pipe 4 so that an edge of thepenetration hole 4 a of the main pipe 4 can press theconnection protrusion 30 along the left side surface inclinedportion 30 b of theconnection protrusion 30. - Thereafter, the
connection protrusion 30 is pressed by the side surface circumference portion of thepenetration hole 4 a, moved downwardly and disassembled from thepenetration hole 4 a. At the state, when the user takes out theauxiliary pipe 6 from the main pipe 4, theauxiliary 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 theconnection protrusion 30 downwardly without contacting directly with theconnection 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.
- 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.
