Hereinafter, the tarp pole of the present invention will be described in detail with reference to the attached drawings.

Referring to FIGS. 1 to 6, the tarp pole according to the first preferred embodiment of the present invention includes a main pole 100 that is curved inward and outward along the circumferential direction based on the cross section, and the main pole 100. ) A plurality of sub-pole stands 200 are provided in a shape corresponding to the main pole stand 100 so that they can be compactly slidable and folded into the inside of the main pole stand 100 and the sub-pole stand 200 are combined. It includes a cap member 300 provided at each node, and a coupling hole 400 provided on one side of the main pole stand 100 and the sub pole stand 200. In addition, the main pole stand 100 and the sub pole stand 200 are provided with the above-described heterogeneous structure and are bent so that they are compactly coupled to each other without any clearance, thereby preventing bending.

In more detail, the main pole stand 100 and the sub pole stand 200 are provided in a sliding structure in which the sub pole stand 200 is folded into the main pole stand 100, so that the length can be adjusted. Additionally, these poles serve to support the camping tarp. At this time, the main pole stand 100 is provided in a hollow shape and has a circular-triangular cross-sectional shape. For example, the main pole 100 has a protrusion 110 that is provided to be curved outward from one surface of the main pole 100, and is adjacent to the protrusion 110 and inward from one surface of the main pole 100. It includes a concave portion 120 that is provided to be curved. In addition, the sub-pole stand 200 has an outer peripheral surface curved to correspond to the protrusion 110 and the concave part 120, so that it can be compactly inserted into the main pole stand 100. For example, the protrusion 110 is provided in a shape in which three of the outer peripheral surfaces of the main pole 100 protrude roundly outward. In addition, the concave portion 120 is formed adjacent to each other and is concave between the protrusions 110. That is, the concave portions 120 are provided between the plurality of protrusions 110 so that three of the outer peripheral surfaces of the main pole 100 are concave inward. Due to this, when the sub-pole stand 200 corresponding to the shape of the main pole stand 100 is inserted into the main pole stand 100, the sub-pole stand 200 is compactly assembled without spinning around within the main pole stand 100. The curved portion is provided in a circular structure to have excellent resistance to buckling load.

Next, the sub-pole 200 includes a first pole 210 connected to the inside of the main pole 100, a second pole 220 connected to the inside of the first pole 210, and the first pole 200. The third pole 230 is connected to the inside of the second pole 220, and each node is installed on the lower inner peripheral surface of the sub-pole 200 and is provided between the main pole 100 and the sub-pole 200. It includes a reinforcing member 240 for reinforcement and an elastic fixing part 250 installed inside the subpole stand 200. In addition, the elastic fixing part 250 includes a fixing tip 251 that can protrude from the inside of the sub-pole 200 to the outside through the coupling hole 400, and the fixing tip 251 and the sub-pole 200. It includes a compression spring 252 that is provided between the inner peripheral surfaces of and applies elastic force to the fixing tip 251. In addition, the fixing tip 251 protrudes when the coupling holes 400 provided in the main pole 100 and the sub-pole 200 respectively form a concentric circle, thereby forming the main pole 100 and the sub-pole 200. so that it can be fixed.

For example, the sub-pole 200 is composed of a first pole 210, a second pole 220, and a third pole 230 that are provided in a shape corresponding to the main pole 100. At this time, the third pole 230 is provided to be thicker than the main pole 100 and the second pole 220. That is, referring to FIG. 6, the thickness of the third pole 230 of the sub-pole 200, which is provided with a smaller diameter than the main pole 100, is 2t, and the main pole 100 and the first pole 100 are provided with a thickness of 2t. (210), by being thicker than the thickness of 1.6t of the second pole 220, the resistance to buckling load of the sub-pole 200 provided on the upper side of the main pole 100 can be increased. As a result, the rigidity of the portion of the third pole 230 that is provided at the top and is further subjected to bending moment can be strengthened.

In addition, the reinforcing member 240 is provided in the form of a hollow pipe and is press-fitted and fixed to the inside of the sub-pole stand 200. In addition, the reinforcing member 240 is disposed in an overlapping portion between the main pole 100 and the sub-pole 200 in a sliding and tensioned state. That is, the reinforcing member 240 is provided inside each node where the main pole 100 and the sub-pole 200 are connected to each other, and serves to reinforce the rigidity of each node.

In addition, the elastic fixing part 250 can fix the main pole 100 and the sub-pole 200 at a preset length when the main pole 100 and the sub-pole 200 are slid and tensioned. It plays a role in ensuring that For example, the fixing tip 251 is provided in the form of a circular protrusion so that it can be drawn in and out through the coupling hole 400. Additionally, the compression spring 252 is connected to the fixing tip 251 and exerts an elastic force so that the fixing tip 251 protrudes outward. Due to this, when the coupling holes 400 provided in the main pole 100 and the sub-pole 200 form a concentric circle, the fixing tip 251 partially protrudes and the main pole 100 and the sub-pole 200 ( 200) to prevent it from sliding. At this time, when the fixing tip 251 is pressed inward by the user, the main pole 100 and the sub pole 200 are released and can slide again.

Next, the cap member 300 is coupled to the lower cap 310, which is coupled to the lower end of the main pole, and each node where the main pole 100 and the sub-pole 200 are folded together to form the main pole 100. ) and a ring cap 320 that prevents clearance between the sub-pole stand 200, and a ring cap 320 that is inserted into the upper end of the sub-pole stand 200, and is provided with a protruding member on one side to facilitate combination with the tarp cloth. Includes top cap 330. For example, the lower cap 310 is provided in a shape that surrounds the lower end of the main pole stand 100 and is provided to be removable. In addition, the bottom cap 310 is provided with a rainwater discharge portion 311 perforated at the bottom to allow rainwater seeping inside to leak out, and increases friction with the ground to allow the main pole 100 to be seated. Let this become solid. In addition, the ring cap 320 is provided in a ring shape with a coupling groove 321 on one surface along the edge so that it can be inserted into the upper ends of the main pole stand 100 and the sub pole stand 200. That is, the ring cap 320 is provided in a circular-triangular shape structure that corresponds to the shape of the main pole stand 100 and the sub pole stand 200 and can be fitted. In addition, the ring cap 320 is disposed between the outer circumferential surface of the main pole 100 and the inner circumferential surface of the sub-pole 200 between the main pole 100 and the sub-pole 200, and is disposed between the main pole 100 and the sub-pole 200. Minimize the clearance between the 100) and the subpole 200. That is, the ring cap 320 compactly couples the main pole 100 and the sub-pole 200 to prevent shaking, thereby preventing load concentration due to bending. In addition, the top cap 330 is inserted into the upper part of the subpole stand 200, and a tarp fixing member 331 is provided on one side. For example, the top cap 330 can be compactly inserted into the upper part of the second pole 220. In addition, the tarp fixing member 331 is provided in the form of a rod that protrudes upward from one surface of the top cap 330, and can be bound to a camping tarp.

Next, the coupling hole 400 is provided in a straight line with a plurality of perforations provided side by side on one side of the main pole stand 100 and the sub pole stand 200, and is provided with the same diameter as the fixing tip 251. do. In addition, the plurality of coupling holes 400 allow the position at which the sub-pole stand 200 and the main pole stand 100 are fixed to be set.

Hereinafter, a second embodiment of the tarp pole according to the present invention will be described. The tarp pole according to the second embodiment has some differences compared to the first embodiment in that a shock absorber for shock attenuation is included inside, and other configurations are the same as the first embodiment, so the tarp pole of the first embodiment is different from the first embodiment. I decide to use the explanation.

Referring to FIG. 7, the tarp pole according to the second embodiment of the present invention includes the sub-pole 200 and a main pole 500 that supports the load of the tarp coupled to the sub-pole 200. In addition, the main pole 500 includes a shock absorber 510 provided inside the main pole 500 to support the load of the sub-pole 200, and when the sub-pole 200 leaves the main pole 500. It includes a step 520 that is provided to prevent this. In more detail, the step 520 is provided in a form that protrudes inward from the inner peripheral surface of the main pole stand 500 so that the inner peripheral surface of the main pole stand 500 is stepped. In addition, the subpole stand 200 is not separated upward by the step 520 and can slide downward. In addition, the shock absorber 510 supports the load of the subpole 200 and serves to attenuate the shock when an external shock occurs. As a result, even if the pole is connected to the tarp and receives strong wind or shock, the shock is attenuated, so that the pole can be firmly supported.

Therefore, according to the present invention, there is an effect that a pole with excellent resistance to buckling load can be provided by providing a circular-triangular deformed structure that is curved inward and outward along the outer peripheral surface. In addition, among the plurality of poles folded in a sliding manner, the thickness of the pole disposed on the upper side is provided to be thicker, which has the effect of reinforcing the rigidity of the vulnerable portion.

The embodiments described above should be understood in all respects as illustrative and not restrictive, and the scope of the present invention is indicated by the claims described later rather than the detailed description above, and the meaning and scope of the claims and their equivalents. All changes or modified forms derived from the concept should be construed as falling within the scope of the present invention.
