It is indispensable for various local events in Korea. Tents are essential equipment for merchants in the market. It is common for these events to be held for three to five days, which requires three to four people to set up a tent, and often takes more than half a day. The place where the entrance was made was usually a lot of public land, such as roads, so it was impossible to set up tents the day before the opening. Therefore, merchants had to spend half a day setting up equipment for as little as three to five days.

In addition, electricity is required to make food, and when the sun goes down, electric lights must be used, so the installation of electric wiring must be accompanied with the installation of tents. Merchants had to pay a professional engineer to rent and install electrical wiring.

As such, the conventional tent was not a simple assembly structure, so a large number of personnel had to be put in, a lot of time was spent, and a lot of money had to be spent on electric wiring.

Therefore, the present invention is to solve the conventional problems as described above, in the expansion and installation of the support pipe of the tent in order to be able to easily and quickly install the tent alone by installing a connection socket at the end of the support pipe of the connection socket It is easy to insert the inner pipe into the support pipe by the receiving guide part, and to make it easy to separate the inner pipe connected by the pressing shape of the connecting socket, so that it is easy to install and remove and provides a fast supporting pipe connecting socket structure. The purpose of the present invention is to provide a support pipe connecting socket structure for firmly fixing the connection portions of two support pipes by a simple operation by incorporating a connection socket with a handle inside the end of the support pipe in unfolding and fixing the support pipe of the tent.

In order to achieve the above object, the present invention is in the connecting socket structure for expanding and fixing the support pipe of the folding tent,

An inner pipe carried by the elastic elastic body and having a protrusion projecting laterally from an end side; A support pipe accommodating the inner pipe, the support pipe having a protruding hole through which the protruding portion protrudes and a guide hole formed in communication with the protruding hole; And a connection socket provided at an end of the support pipe and having a pressing shape inserted into the guide hole and guided therein.

The connecting socket is moved along the guide hole so that the protruding portion is pressed into the protruding hole by the pressing portion so that the support pipe and the inner pipe are released and released. This structure provides a quick and easy way to disengage the inner pipe and the support pipe by simply moving the connecting socket.

Here, the end of the inner pipe may include a gripping means for easily taking out the inner pipe received in the support pipe from the support pipe.

Here, the guide hole may be formed in the longitudinal direction at a portion closer to the end of the support pipe than the protruding hole, the guide hole may be formed to be narrower than the protruding hole. By narrowing the width of the guide hole, it is possible to prevent the protrusion from flowing.

Here, the cross section of the inner pipe, the support pipe and the connecting socket may have a rectangular shape. The rectangular shape prevents rotation between the inner pipe and the support pipe, thereby facilitating and solidifying the bond and being resistant to bending moments.

Here, the end of the protrusion may have a rounded shape, and the pressing portion may include a surface inclined in the direction of the protrusion. This shape makes the operation natural when the pressing shape presses the protrusions, and also allows the protrusions to slide in contact with the inner surface of the support pipe when the inner pipe is inserted into or taken out of the support pipe.

Here, the auxiliary guide shape is formed on the inner side of the connection socket facing the pressing portion, and the support pipe may be formed to form an auxiliary guide hole for guiding the auxiliary guide shape. By providing an auxiliary guide function, it is possible to securely control the movement of the hook connector, to make the movement solid, and to prevent the connecting socket from being separated from the support pipe.

Here, the connection socket protrudes outward in the longitudinal direction than the support pipe,

The end of the protruding connecting socket has an inner cross-sectional shape of the end of the connecting socket larger than the inner cross-sectional shape of the support pipe, and an inner cross-sectional shape of the connecting socket adjacent to the end of the support pipe has an inner cross-sectional shape of the support pipe. It may be provided with a receiving guide of the inner cross-sectional shape gradient in the longitudinal direction. This provides convenience when inserting the inner pipe into the support pipe.

Here, the play corresponding to the length of the guide hole is present between the accommodation guide portion and the end of the support pipe,

A protruding portion is formed in the connection socket positioned on the same line as the guide hole and connected to the accommodation guide portion and has a protrusion preventing portion having a length corresponding to the clearance, and a protruding portion at the end of the support pipe positioned on the same line as the guide hole. A narrower width is formed in the slit formed to allow the protrusion preventing portion to enter and exit when the connection socket is moved,

When the inner pipe is inserted and withdrawn, the protrusion may be prevented from being protruded into the play portion by being pressed by the protrusion preventing portion. In addition, since the width of the slit is narrower than the protrusion, it is possible to prevent the protrusion from the slit.

In addition, in order to achieve the above object, the present invention in the connecting socket structure for connecting and fixing the support pipe of the folding tent,

A connecting socket having a guide handle fixed to the side and a protrusion which is protruded from the side by being supported by the elastic body built in; A support pipe on one side for accommodating the connection socket and having a guide portion formed in a longitudinal direction in communication with the locking portion to allow the guide handle to be fixed and the guide handle to be movable in the longitudinal direction; Including; a support pipe of the other side having a protrusion hole for projecting the protrusion;

After unfolding the support pipe, the guide handle is separated from the locking part and moved along the guide line to insert a part of the connection socket accommodated in one of the support pipes into the other support pipe so that the protrusion of the connection socket is projected into the protruding hole of the other support pipe. By being fitted, the support pipe can be connected and fixed.

Here, the one side of the support pipe is provided with a spring in one end is fixed and supported, the other end in the longitudinal direction such that the other end toward the end of the support pipe, the connection socket is supported on the other end of the spring to provide elastic force in the direction of the end of the support pipe By receiving, the guide handle portion is separated from the locking portion can be connected to the other side of the support pipe by itself by the elastic force of the spring.

Here, both support pipes may be connected to the hinge at the end. The hinge structure provides convenience when unfolding the support pipe.

Here, the recess may be formed around the protruding hole formed on the side of the other support pipe so as to easily press the protruding portion.

On the other hand, in the connecting socket structure for connecting and fixing the support pipe of the folding tent,

A connecting socket having a guide handle fixed to the side;

A support pipe on one side for accommodating the connection socket and having a guide portion formed in a longitudinal direction in communication with the locking portion to allow the guide handle to be fixed and the guide handle to be movable in the longitudinal direction; A spring having one end fixed and supported by the one side support pipe, the other end being installed in the longitudinal direction such that the other end faces the end of the support pipe, and supporting the connection socket; Including; the support pipe of the other side and the support pipe of the other side connected by a hinge at the end;

After the support pipe is unfolded, when the guide handle portion is separated from the locking portion, the connection socket received in one of the support pipes is partially inserted into the other support pipe by the elastic force of the spring.

Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the connecting socket structure of the folding tent according to the present invention.

1 is a perspective view showing a folded tent according to the present invention, Figure 2 is a perspective view showing a state in which the folding tent of FIG. Members constituting the skeleton of the folding tent can be largely divided into the center pipe 10, the first and second diagonal support members 20 and 21, the holding pipe 30, the support pipe 40. In the embodiment of the present invention shown in Figure 1, the length of the support pipe 30 or the support pipe 40 is about 1.5 meters. This tent is pushed up the center pipe (10) located in the center of the tent to install the tent, the diagonal support member (20, 21) is unfolded, the holding pipe (30) constituting the four pillars of the tent is opened, the tent is fully unfolded It is designed to be (see FIG. 2). At this time, the wheel 31 may be installed at the lower end of the holding pipe 30 so that the holding pipe 30 can be easily opened.

If the person who wants to install the tent pushes up the center pipe 10 to the end, and the diagonal support members 20 and 21 are fully extended and settled, and the holding pipe 30 is in place, the role of the girder will be described in detail below. Fix or expand fixed, support pipe (40) to be installed. After installation of the support pipe 40, the prop pipe 30 is expanded. Since the prop pipe 30 is about 1.5 meters inconvenient to operate, the pipe 30 having a smaller cross-sectional area is built into the pipe 30 having a larger cross-sectional area such as an indoor TV antenna or a fishing rod, and then, when necessary, the internal pipe 32 is pulled out. This will extend the overall pipe length. The height of the tent can then be extended beyond 2.3 meters, the height of which does not interfere with the activity.

Hereinafter, the installation of the support pipe 40 will be described. 3A is a side view showing a state in which a wide tent is folded, FIG. 3B is a side view illustrating a process of unfolding the tent of FIG. 3A by lifting a center pipe, and FIG. 3C is a side view illustrating the tent of FIG. 3A. Figure 4a is a side view showing a state in which the narrow tent is folded, Figure 4b is a side view showing the state of the process of the tent of Figure 4a is unfolded by lifting the center pipe, Figure 4c is a side view showing the tent of Figure 4a unfolded.

The present invention goes in two directions. As shown in Figs. 4A, 4B and 4C, if the width of the tent is about 3 meters, only two support pipes 40 may be connected and fixed (in this case, the length of the support pipes 40 is approximately 1.5 meters). If you need a width of more than 4 meters, the two support pipes 40 only need to be large because the tent in the folded state increases (in this case, the length of the support pipes 40 should be about 2 meters or more). The performance and portability of the folding tent is lost. Therefore, to carry a tent of more than 4 meters in width, if you want to configure the length of the tent is about 1.5 meters or less in the folded state, the length of the prop pipe 30 is extended by the built-in pipe 33 It is preferable to use the same principle. This is the way shown in Figures 3A, 3B and 3C.

Referring to FIGS. 3A, 3B, and 3C, when the diagonal support members 20 and 21 operate in succession of lifting the center pipe 10, both support pipes 30 are opened to support the second diagonal support. The moving bracket 32 connected to the member 21 goes up along the support pipe 30. Then, between the moving bracket 32 of the support pipe 30 and the fixed bracket 41 of the support pipe 40, the support pipe 40 is connected to the support pipe 30 by an intermediate member 5 connected to each other by a hinge. The hinge connection point h is lifted about the center. In the lifted state (see FIG. 3C), the inner pipe 42 (shown in dotted lines) built in one side of the support pipe 40 is pulled out and fixed to the other side to connect the support pipes 40 on both sides.

The present invention draws the inner pipe 42 from the one side (left side in FIG. 4C) support pipe 40 in the process of unfolding the tent, and connects and fixes the support pipe 40 on the other side (right side in FIG. 4C), and It is convenient to release one side (right side in FIG. 4C) of the inner pipe 42, which is connected and fixed to both side support pipes 40 in the process of folding the tent, and put the other side (left side in FIG. 4C) into the support pipe 40. It is about the connection socket structure to provide.

Figure 5a is an exploded perspective view showing the connecting socket of the support pipe of the tent shown in Figure 3c, Figure 5b is a perspective view showing the left end of the right support pipe of Figure 3c, Figure 5c is a perspective view showing the right end of the inner pipe. Figure 6a is a cross-sectional view showing aa cross section and bb cross section of Figure 5a, Figure 6b is a side cross-sectional view of the support pipe of Figure 5b with the connection socket of Figure 5a is installed, Figure 6c is the internal pipe inserted into and fixed to the support pipe of Figure 6b Side cross-sectional view showing the state.

A hole 421 is formed on the end side of the inner pipe 42 of FIG. 5C as a gripping means, which uses a screwdriver or the like to take the inner pipe 42 out of the one side support pipe 40. It is a means to stably hold. Through the protrusion hole 425 formed on the upper surface of the inner pipe 42, a protrusion 423 having a rounded head portion protrudes. A lower portion of the protrusion is formed with a lower portion of the protrusion 422 is larger than the protrusion hole to prevent the protrusion 423 is completely protruded, the lower member 422 is an elastic body inserted into the inner pipe (42) ( 424).

The support pipe 40 of FIG. 5B has a circular protrusion hole 401 having a shape corresponding to the shape of the protrusion 423 on the upper surface thereof, a narrower width than the protrusion hole 401, and communicating with the protrusion hole 401. The guide hole 402 which opens in the end side of the support pipe 40 is formed. The upper end of the support pipe 40 has a slit 403 having the same width as that of the guide hole 402 and opened to the end side. An auxiliary guide hole 404 is formed on the lower surface of the support pipe 40.

The connection socket 43 of FIG. 5A has a shape in which a central portion of the upper and lower surfaces is recessed to have a shape that is easy to grip by hand, and an inner shape thereof is sized to accommodate the support pipe 40. An auxiliary guide shape 433 is formed on the lower surface of the inside of the upper surface (see the lower figure of FIG. 6A). The auxiliary guide shape 433 is fitted into the auxiliary guide hole 404 of the support pipe 40 (see FIG. 6B). Their coupling structure restricts the operation section in the longitudinal direction of the connection socket 43. If the connecting socket 43 is made of plastic, it is elastic to some extent, so that the auxiliary guide shape 433 may be provided in the auxiliary guide hole 404 without great difficulty when mounting the connecting socket 43 to the support pipe 40 in the tent manufacturing process. ) Can be inserted.

The pressing portion 438 is formed on the upper surface of the connecting socket 43. The pressing portion 438 is separated from the upper surface of the connecting socket 43, the three sides for convenience in the manufacturing process of the tent, only one side is connected (see the upper figure of Figure 6a). If there is some elasticity in the connection socket 43, the guide hole 402 of the support pipe 40 to the pressing shape portion 438 without great difficulty in mounting the connection socket 43 to the support pipe 40 in the tent manufacturing Can be inserted into After inserting the pressing portion 438 into the guide hole 402, the pressing portion 438 is inserted into the groove 437 above the connection portion of the pressing portion 438 so that the pressing portion 438 does not lift up. After the clip 431 is pushed in, the screw 432 having a large head is screwed into the screw hole 435 so that the lower surface of one side of the head restrains the clip 431 (see FIG. 6B). After the screw 432 is engaged, the push portion 438 is no longer lifted up by the screw head.

The pressing portion 438 in the guide hole 402 is capable of reciprocating in the longitudinal direction. An inclined surface 439 exists in the pressing portion 438. The guide hole 402 and the protruding hole 401 communicate with each other so that the inclined surface 439 can move to the protruding hole 401. The inclined surface may press the rounded shape of the protrusion more smoothly.

Receiving guide portion 434 is formed on the upper and lower ends of the end of the connecting socket 43. The height of the inlet of the accommodation guide portion 434 is preferably higher than the protrusion of the protrusion 423 of the inner pipe 42 for convenience of insertion of the inner pipe 42. The accommodating guide part 434 is formed in a gradient shape in which the inner area becomes narrower gradually from the entrance to the inside, and is formed in the inclined surface as shown in FIG. 6B in the present embodiment. The inner end of the receiving guide portion 434 is formed so that the height and the inside of the end face of the support pipe 40 coincide with the insertion of the inner pipe. In the present embodiment, the accommodating guide portion 434 is formed only on the inner upper and lower surfaces, but may be further formed on the left and right surfaces. G between the inner end of the receiving guide portion and the end of the support pipe 40 so that the pressing portion 438 of the connecting socket 43 can be reciprocated in the longitudinal direction along the guide hole 402 (G) Is formed.

In the central portion of the inner end portion of the upper portion of the receiving guide portion 434, a protrusion preventing portion 436 having a shape corresponding to the slit 403 of the support pipe 40 is formed. The reason for forming the protrusion preventing portion 436 and the slit 403 is that the protrusion portion of the inner pipe 42 is inserted between the accommodation guide portion 434 and the support pipe 40 during insertion of the inner pipe 42. This is to prevent the projecting on. Since the width of the protrusion 423 is greater than the width of the slit 403 and the guide hole 402, when the inner pipe 42 is inserted into the support pipe 40, the protrusion 423 is accommodated in the receiving guide 434. By the protruding portion 436, and then continues to be pressed by the protruding portion 436, and then passes through the narrow slit 403 and the guide hole 402 while being kept pressed. Until it protrudes (see FIG. 6C). The inner pipe 42 is securely connected to the support pipe 40 by the protrusion of the protrusion 423.

The inner pipe 42 has a symmetrical structure on both sides, and the two support pipes 40 also have the same shape at both ends thereof, and the same connecting socket 43 is mounted thereon. As shown in FIG. 3A, the tent is folded. Even in the state, the right protrusion 423 of the inner pipe 42 protrudes into the protruding hole formed at the end of the left support pipe 40, thereby making it possible to stably receive the inner pipe in the one support pipe.

Installation of the support pipe 40 is completed when the protrusions 423 at both ends of the inner pipe 42 protrude through the protruding holes 401 on both sides of the support pipe 40.

The principle of dismantling the support pipe 40 installed as above to fold the tent is simple. Referring to FIG. 6C, the operator grasps the inner pipe 42 with his left hand and pulls it to the left while pulling the connection socket 43 with his right hand, and pushing the portion 438 along the guide hole 402. Moves to the right, so that the inclined surface 439 of the pressing portion 438 presses the protrusion 423 having the round head portion. When the protruding portion 423 is pressed into the support pipe 40, the operator pulls the inner pipe 42 to the left, and thus, the guide hole 402 and the slit 403 in the reverse order to the insertion process of the inner pipe 42. The protrusion 423 is pressed out of the support pipe 40 while maintaining the pressed state through the protrusion preventing portion 436. Therefore, the operator can easily and quickly separate the inner pipe 42 by only pulling the inner pipe 42 and the connecting socket 43.

Here, the longitudinal movement distance of the connection socket 43, the distance that the auxiliary guide shape 433 is guided in the auxiliary guide hole 404, the pressing portion 438 is the guide hole 402 and the protruding hole 401 The distance guided over, the clearance G, and the lengths of the protruding portions 436 and the slits 403 are preferably the same, but not all of them need to be the same unless interference occurs in the operation of the connecting socket 43. .

The inner pipe 42 and the support pipe 40 are shown in a rectangular shape, but are not necessarily limited to this shape. However, since the rectangular shape has the advantage of improving the bending moment resistance property of the support pipe 40 and preventing the inner pipe 42 inside the support pipe from relatively turning relative to the support pipe 40, the present invention In the example of the square shape was selected.

As described above, it is preferable to apply the above structure when the tent width is larger than approximately 4 meters. Hereinafter, the supporting structure of the support pipe 40, which is preferably applied in a tent having a width of about 3 meters, will be described.

Figure 4a is a side view showing a state in which the tent is not large width folded, Figure 4b is a side view showing the process of unfolding the tent of Figure 4a by lifting the center pipe, Figure 4c is a side view showing the tent of Figure 4a unfolded. .

As shown in Figure 4a, the intermediate portion of the folded support pipe 40 is connected by a hinge (H). The state in which the support pipe 40 is lifted about the hinge axis h is shown in FIG. 4B. Since the principle is as described in the above-mentioned wide tent structure, it is omitted. When the tent is unfolded, as shown in FIG. 4C, the support pipe 40 is extended while being connected to the hinge H at an intermediate point to form a straight line. Then, the operator connects both of the support pipes 40 by hooking the internal connection socket 60 installed at the end of one side of the support pipe 40 to the other support pipe 40.

FIG. 7A is a side cross-sectional view showing a connection portion of both support pipes of FIG. 4A, and FIG. 7B is a side cross-sectional view showing an unfolded state of both support pipes of FIG. 7A, and FIG. 7C is a diagram showing the internal connection socket of FIG. 7B being inserted into the right support pipe. Side cross-sectional view showing the state. 8A is a plan view of the support pipe connecting portion of FIG. 4C, FIG. 8B is a rear cross-sectional view of FIG. 7B, and FIG. 8C is a rear cross-sectional view of FIG. 7C.

Referring to FIG. 7A, both support pipes 40 are rectangular in shape, and hinge members 49 are welded to the ends thereof, and both hinge members 49 are connected by hinges H. As illustrated in FIG. Hinge member 49 may be formed with a plurality of members surrounding the axis of the hinge (H) for firmness. In the embodiment of the present invention in particular, as shown in Figure 8a, the left hinge member 49 is formed of two, the right hinge member 49 is formed of three, but the number or shape is not particularly limited.

A spring support 61 is installed at one end of the support pipe 40, and a spring 62 having one end supported by the spring support 61 is elastically acted in the longitudinal direction of the support pipe 40. At the other end of the spring 62, an internal connection socket 60 having a circular cross section is installed while the spring 62 is compressed. Since the inner connecting socket 60 of the circular cross section enters inside the support pipe 40 of the rectangular cross section, the inner connecting socket 60 is rotatable within the supporting pipe 40.

Referring to FIGS. 7B and 8B, an elastic body 602 is built in the inside of the internal connection socket 60 (a portion near the end of the support pipe 40), and the protrusion 603 is formed in the elastic body 602. ) Is protruded so as to protrude through the protruding hole 601 formed in the inner connection socket 60. When the internal connection socket 60 is installed under the compression of the spring 62, the protrusion 603 is blocked by the inner surface of the support pipe 40 and cannot protrude.

Meanwhile, the other side (right side in the drawing) support pipe 40 has a protrusion hole 48 through which the protrusion 603 protrudes, and around the protrusion hole when the tent is dismantled, the protrusion 603 is a protrusion hole 48 by hand. The depression 481 is formed so as to be easy to push in.

Inside the connection socket 60 (a part far from the end of the support pipe 40), a guide handle 604 fixed to the internal connection socket 60 is provided. A guide line 47 is formed in the lower surface of the support pipe 40 in the longitudinal direction, and a locking portion 46 is formed at one side of the guide line 47 far from the end of the support pipe 40. It communicates in the shape bent substantially vertically in the longitudinal direction. The guide handle 604 is fitted to guide along the locking portion 46 and the guide line 47. In the manufacture of the tent, the guide handle 604 may be manufactured by using a manufacturing method commonly used, such as riveting or screwing in a state in which the guide line 47 is fitted.

Before installing the tent, as shown in FIGS. 7B and 8B, an internal connection socket 60 is embedded at one side while compressing the spring 62. At this time, in order to withstand the elasticity of the spring 60, the guide handle 604 is caught in the locking portion 46.

When the tent is installed, as shown in FIGS. 7C and 8C, when the guide handle 604 is moved from the locking portion 46 toward the guideline 47, the elasticity of the spring 62 prevents the guideline 47. As the length of the connection socket 60 is advanced, approximately half of the internal connection socket 60 is inserted into the other support pipe 40 and the protrusion 603 through the protruding hole 48 in the other support pipe 40. ) Will protrude. In this state, the internal connection socket 60 reliably connects and fixes both support pipes 40.
