  • an enlarged portion having a large diameter may be formed on one end of the tent pole into which the insert pole is inserted.
  • the insert pole has an outer diameter corresponding to an inner diameter of the enlarged portion.
  • sizes of the enlarged portion and the insert pole are preferably made such that the inertia moment of the insert pole is 65 ⁇ 130% of inertia moment of the enlarged portion.
  • the insert poles may be arranged to the body in two or more rows in a vertical direction.
  • FIG. 1 is a perspective view of a tent assembled with a connector for a tent pole according to the prior art
  • FIG. 2 is a perspective view of a connector for a tent pole according to the prior art

  • FIG. 4 is a perspective view of a connector for a tent pole according to an embodiment of the present invention.
  • FIG. 5 is a transverse sectional view of FIG. 4 ;
  • FIG. 6 is a perspective view of a connector for a tent pole according to another embodiment of the present invention.
  • a connector 10 for a tent pole has a tubular body 11 and a plurality of insert poles 12 connected radially to a periphery of the body 11 .
  • An outer diameter of the insert pole 12 is made to be smaller than an inner diameter of a tent pole 20 .
  • Each of the insert poles 12 is inserted into one end of the tent pole 20 , so that the plurality of tent poles 20 are radially connected to each other through the connector 10 .
  • the connector 10 is provided with the four insert poles 12 and the four tent poles 20 are connected to the connector 10 .
  • the number of the insert poles 10 is not limited thereto and can be increased or decreased based on the number of the tent poles 20 to be connected.
  • a plurality of tap holes 13 are formed along a periphery of the body 11 at an interval, and an external screw portion 12 a corresponding to the tap hole 13 are formed on one end of the insert pole 12 .
  • the external screw portion 12 a is screw-engaged to the screw hole 13 of the body 11 , so that the body 11 and the insert pole 12 are connected to each other.
  • the tent pole 20 is connected to the connector 10 via the insert pole 12 without being directly connected to the body 11 of the connector 10 , so that it is possible to reduce the whole size and thus the weight of the connector 10 .
  • one end of the tent pole 20 into which the insert pole 12 is inserted is provided with an enlarged portion 21 having a diameter larger than the other portion.
  • the insert pole 12 has an outer diameter equal to an inner diameter of the enlarged portion 21 or preferably smaller than an inner diameter of the enlarged portion 21 by about 0.1 mm so as to be easily inserted in the enlarged portion 21 .
  • the enlarged portion 21 is formed to have a length corresponding to that of the insert pole 12 at the end of the tent pole 20 .
  • I inertia moment
  • M is a mass
  • R is an inner radius of tube
  • a magnitude of the inertia moment is proportional to the diameter of the tent pole 20 or insert pole 12 . Accordingly, the inertia moment of the enlarged portion 21 of the tent pole 20 is larger than that of a non-enlarged portion 22 of the tent pole 20 or insert pole 12 having a diameter smaller than the diameter of the enlarged portion. Since a large inertia moment is meant by a large bending stiffness, the enlarged portion 21 has a larger bending stiffness, compared to the non-enlarged portion 22 and the insert pole 12 .
  • an outer diameter of the external screw portion 12 a of the insert pole 12 is formed to be larger than that of the other portion, it is possible to prevent the insert pole 12 from being damaged at a “C” portion when the bending stress is applied.
  • the reason to determine the inertia moments of the tent pole 20 and the enlarged portion 21 based on the insert pole 12 is as follows: if the determination is made based on the non-enlarged portion 22 of the tent pole 20 , the insert pole 12 is deficient in the inertia moment, so that the insert pole 12 may be damaged when the bending stress is applied.
  • the reason why the ratio of the inertia moment of the insert pole 12 to the inertia moment of the enlarged portion 21 is made to be 65% or more is as follows: if a ratio is smaller than the above ratio, the insert pole 12 itself may be damaged when the bending stress is applied.
  • a following table shows an experimental example of determining the sizes of the tent pole 20 , the enlarged portion 21 and the insert pole 12 .
  • the tent pole 20 and the insert pole 12 were made of aluminum.
  • Tent pole 10.25 9.05 0.600 212.4 86.3 73.0 Enlarged 10.80 9.60 0.600 250.8 portion
  • Insert pole 9.50 8.15 0.675 183.2 (*inertia moment ratio 1: inertia moment of insert pole/inertia moment of tent pole; inertia moment ratio 2: inertia moment of insert pole/inertia moment of enlarged portion)
  • the ratio of the inertia moment of the insert pole 12 to the inertia moment of the enlarged portion 21 is 71.6%, and thus the damage of the tent pole 20 can be prevented.
  • the outer diameter of the tent pole 20 is increased to 10.25 mm, it is possible to set the ratio of the inertia moment of the insert pole 12 to the inertia moment of the enlarged portion 21 at 73% by increasing the outer diameter of the enlarged portion 21 to 10.8 mm and employing the insert pole 12 having an outer diameter of 9.5 mm and a thickness of 0.675 mm.
  • the outer diameter of the tent pole 12 is increased, it is possible to maintain the inertia moment ratio to about 65 ⁇ 75% by increasing the outer diameters of the enlarged portion 21 and the insert pole 12 . At this time, the thickness of the insert pole 12 is instead reduced. Accordingly, even when the outer diameter of the tent pole 20 is increased, the weight of the insert pole 12 may be scarcely increased.
  • the ratio of the inertia moment of the insert pole 12 to the inertia moment of the enlarged portion 21 may be practically about 130% at the maximum.
  • the tent pole 20 having an outer diameter of 9 mm and a thickness of 0.6 mm and the enlarged portion having an outer diameter of 9.5 mm
  • a practical thickness of the insert pole 12 is 1.6 mm, of which the inner diameter is 5 mm.
  • FIG. 6 is a perspective view of a connector according to another embodiment of the invention.
  • the connector 30 comprises a cylindrical body 31 and a plurality of insert poles 32 intersectingly connected to the body 31 in vertical directions.
  • the body 31 is formed with a plurality of tap holes 33 intersectingly arranged in vertical directions.
  • the connector 30 since the insert poles 32 are vertically arranged in two or more rows so that the tent poles can be connected, the tent poles can be connected without increasing a diameter of the body 31 . Accordingly, the weight increase of the connector 30 can be minimized.
  • the body 11 , 31 having a cylindrical shape
  • the body is not limited thereto and may be formed into various tubular shapes having a polygonal section such as quadrangle, triangle and the like.
  • the tent pole is connected to the connector via the insert pole without being directly connected to the cylindrical body. Accordingly, it is possible to minimize the size and the weight of the connector and to prevent the tent pole from being damaged at the connection region with the connector when the bending stress is applied to the tent pole.
  • the one end of the tent pole into which the insert pole is inserted is formed with an enlarged portion having a large diameter, so that the damage of the tent pole due to the bending stress can be prevented, more positively.
