Description

Pole connection structure

[0001] The present invention relates to a pole connecting structure, and more particularly, to a pole connecting structure that simplifies the connection between poles of different diameters, thereby facilitating installation, and allows the connecting portion between the poles to continuously maintain a connected state without shaking.

[0002]

[0003] In general, as culture develops and life becomes more affluent, our daily lives have changed a lot, and many people have come to prefer leisure activities to relax from the stress of busy daily life, and many products for leisure activities have been introduced, so many people purchase leisure products that suit their tastes and use them when going on leisure activities or camping.

[0004] This refers to purchasing a camper van, equipping it with various types of camping equipment, and then unfolding and using the camping equipment depending on the location. For example, camping equipment may refer to tents, shade cloths, and awnings, and these camping equipment are installed with the support of poles.

[0005] The above conventional pole is equipped with a plurality of pipes of a certain length to enable easy portability and storage, and has a fitting tube at one end of the pipe with the same inner diameter as the pipe, so that the fitting tube can be fitted into the inside of the tip of another pipe so that the two pipes can be connected to each other, and the pipes are connected to a length required for use.

[0006] However, the conventional poles as described above are designed to connect multiple pipes of a certain length, so there is a risk of loss, and there is a problem in that the length cannot be freely adjusted depending on the installation location because the length of the number of pipes to be connected is limited.

[0007] In order to solve the above problems, a pole has recently been introduced and used that is made by combining multiple pipes that are sequentially inserted into the inside in a sliding manner rather than by separation and assembly.

[0008] In this conventional pole, a second pipe is inserted into a first pipe, and a third pipe is inserted into the second pipe, and the length can be freely adjusted by sliding them, so that the length of the pole can be conveniently adjusted according to the installation location and installation product of camping equipment. However, since the pipes that make up the pole are sequentially inserted and the length is adjusted by sliding, if the inner diameter of the first pipe and the outer diameter of the second pipe are the same, the slide does not run smoothly. Therefore, the outer diameter of the second pipe inserted inside the first pipe is made smaller than the inner diameter of the first pipe so that the smooth slide can be achieved while preventing the generation of surface friction between them. However, if the pole is extended long due to the gap between these, each pipe shakes, which not only reduces the stability of the pole, but also various foreign substances can enter the inside of each pipe through the gap, and if the foreign substances that have entered get stuck in the gap, the pipes cannot slide smoothly, making it difficult to use.

[0009] In addition, the pipes currently in use are circular, so when the length of the pole pipe is extended, the hooks provided at the end of each pipe are hooked to the hook holes provided at the front end. However, if the pipes are circular, there is an inconvenience in that each pipe rotates arbitrarily and the hooks cannot be accurately aligned with the hook holes.

[0010] On the other hand, the pole that adjusts the length by fixing the pole with an inner spring by drilling a hole could not be drilled in many holes, so it was not possible to adjust the length as desired, and there was a problem with the durability of the pole when fully extended because there was no part that connected the pole to the other pole.

[0011] Also, although there is a pole connection part, the pole fixing part is on the inside of the pole, so most low-cost poles use this method of holding and turning the poles to fix them, but it has the disadvantage of being weak in durability and the pole turning and becoming unlocked with just a little impact.

[0012]

[0013] Therefore, the purpose of the present invention to solve the conventional problems as described above is to provide a pole connection structure that simplifies the connection between poles with different diameters and facilitates installation.

[0014] Another object of the present invention is to provide a pole connection structure that can continuously maintain a connection state without shaking the connection portion between poles.

[0015] Another object of the present invention is to improve the problem of the pole being easily unlocked even with a small impact in a method of holding and turning the pole and fixing it.

[0016] Another object of the present invention is to provide a pole connection structure that provides a structure having a connection and separation prevention function to the pole itself, so that connection between poles is easy without a complex structure and has excellent connection strength.

[0017]

[0018] The present invention, in order to achieve the above-described object, discloses a pole connection structure comprising: a large-diameter main pole; a small-diameter sub-pole installed in a contractible or expandable manner on the main pole; and a release locking device installed at a boundary portion between the main pole and the sub-pole to enable locking and releasing operations of the pole, wherein the main pole and the sub-pole further include longitudinal grooves formed to correspond to each other on both longitudinal sides thereof, and wherein the sub-pole is installed in the main pole in a manner that it can slide along the longitudinal groove, and the pole is fixed at a predetermined fixed position by the pole locking device.

[0019] In addition, the longitudinal grooves formed to correspond to each other between the main pole and the sub pole may be characterized in that they are configured so that when the main pole and the sub pole are combined, the respective longitudinal grooves are tightly fitted together so that left and right rotation is controlled.

[0020] In addition, the pole fastening device may be characterized by including a cylindrical fixing member that is fixedly joined to the outer diameter of the main pole; and a fixing cap that is installed so as to be fixed so as to be tightly fixed to a longitudinal groove of a sub pole that is coupled with the main pole while being wrapped around the upper outer periphery of the fixing member.

[0021] In addition, the fixing member may be characterized by comprising: a body connecting portion that is coupled to the main pole; an elastic socket portion that is formed by extending a certain height upward from the body connecting portion and being split and formed so as to be freely opened and contracted; a first fixing protrusion that protrudes from one side of the inner side of the elastic socket portion and is formed to be seated in a longitudinal groove of the sub pole; and a second fixing protrusion that protrudes from one side of the outer side of the elastic socket portion and is formed to be seated and fixed with the fixing cap.

[0022] In addition, the above-mentioned fixed cap may be characterized by including a cylindrical body having an inner diameter that is open in the upper and lower directions; and an inner engaging groove formed in a groove shape at one side along the inner diameter surface of the body in correspondence with a second fixing protrusion that protrudes from one side of the outer surface of the elastic socket portion of the fixed member.

[0023] In addition, the elastic socket portion of the fixing member may be formed corresponding to the internal hooking groove of the fixing cap, and one side may be formed with an inclined surface that guides rotation when the fixing cap rotates on its own; and an extension surface that extends from the inclined surface to a place where the second fixing protrusion is located.

[0024]

[0025] The present invention can provide a pole connection structure that simplifies the connection between poles with different diameters, thereby facilitating installation.

[0026] In addition, the present invention can provide a pole connection structure that can continuously maintain a connection state without shaking the connection portion between poles.

[0027] In addition, the present invention has the effect of improving the problem of the pole being easily unlocked even with a small impact in a method of holding and turning the pole to fix it.

[0028] In addition, the present invention provides a structure having a connection and separation prevention function to the pole itself, thereby providing a pole connection structure that is easy to connect between poles without a complex structure and has excellent connection strength.

[0039] The present invention is susceptible to various modifications and embodiments. Specific embodiments are illustrated in the drawings and described in detail in the detailed description. However, this is not intended to limit the present invention to specific embodiments, but rather to encompass all modifications, equivalents, and alternatives falling within the spirit and technical scope of the present invention.

[0040] The present invention is not limited to the embodiments disclosed below, but can be implemented in various different forms, and the present embodiments are provided only to ensure that the disclosure of the present invention is complete and to fully inform a person having ordinary skill in the art of the scope of the invention.

[0041] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. First, when assigning reference numerals to components in each drawing, it should be noted that, where possible, identical components are assigned the same reference numerals even if they appear in different drawings. Furthermore, when describing the present invention, if a detailed description of a related, well-known structure or function is judged to obscure the gist of the present invention, such detailed description will be omitted.

[0042] Figures 1 to 6 are examples showing a pole connection structure according to the present invention.

[0043] Referring to FIGS. 1 to 5, the pole connection structure of the present invention comprises a large-diameter main pole (110); a small-diameter sub pole (120) installed to be contractible or expandable from the main pole (110); and a pole locking device (200) installed to lock the boundary portion of the main pole (110) and the sub pole (120) at a length adjustment fixed position.

[0044] The above main pole (110) may be configured to include a pipe-shaped body (111) having a certain length, an open hole (111a) formed as a space into which a sub pole (120) is inserted with an inner diameter of a certain width, and a longitudinal groove (113) formed to correspond to each other on both longitudinal sides of the main pole (110). At this time, the longitudinal groove (113) may be manufactured in any form, such as punching or injection molding, and a groove structure having a longitudinal groove is sufficient.

[0045] The above sub-pole (120) can be configured to include a pipe-shaped body (121) having a certain length, an open hole (121a) formed as a space with an inner diameter of a certain width, and a longitudinal groove (123) formed to correspond to each other on both longitudinal sides of the sub-pole (120).

[0046] Here, as shown in FIGS. 4 to 6, the main pole (110) and the sub pole (120) have longitudinal grooves (113) (123) formed on both longitudinal sides to correspond to each other, and when the main pole (110) and the sub pole (120) are joined, the respective longitudinal grooves (113) (123) can be configured to fit tightly and control left and right rotation. This prevents the poles from coming off or losing their fixing power due to wind or collision during tent installation.

[0047] Preferably, one end of the sub-pole (120) is inserted and slidably connected to one end of the main pole (110), so that each longitudinal groove (113) (123) of the sub-pole (120) in the main pole (110) is installed so as to be able to slide with each other, and is fixed at a certain position by the pole locking device (200).

[0048] Also preferably, the longitudinal groove (113) of the main pole (110) is formed in a recessed shape in the outer diameter of the body (111) and protrudes toward the inner diameter, and can be configured to be inserted into the inner side of the longitudinal groove (123) of the sub pole (120).

[0049] The above pole fastening device (200) is configured to be coupled to the connecting portion of the main pole (110) and the sub pole (120) and to be mutually fixed by internal elastic tightening, and may be configured to include a cylindrical fixing member (210) coupled to the outer diameter of the main pole (110); and a fixing cap (220) that is inserted and coupled to surround the upper outer periphery of the fixing member (210) and is installed to be fixed in a form that closely contacts the longitudinal groove (123) of the sub pole (120) coupled to the main pole (110).

[0050] The above-mentioned fixing member (210) may be configured to include a body connecting portion (211) that is coupled to the main pole (110); an elastic socket portion (213) that is formed to extend upward from the body connecting portion (211) to a certain height and is split and formed to be freely opened and contracted; a first fixing protrusion (215) that protrudes from one side of the inner side of the elastic socket portion (213) and is formed to be seated in the longitudinal groove (123) of the sub pole (120); and a second fixing protrusion (217) that protrudes from one side of the outer side of the elastic socket portion (213) and is formed to be seated and fixed with the fixing cap (220).

[0051] Here, the first fixing projection (215) is formed to be caught in the longitudinal groove (123) of the sub-pole (120) to provide a structure for fixing the pole in the current position, and the second fixing projection (217) can provide a structure for allowing the fixing cap (220) to be repeatedly locked and released by temporary rotation.

[0052] That is, when the main pole (110) and the sub pole (120) are combined, the first fixing projection (215) is caught in the longitudinal groove (123) of the sub pole (120) to perform primary fixation at the current pole position, and the fixing cap (220) that is combined to be covered on the outside of the fixing member (210) is temporarily rotated to be fixed to the second fixing projection (217) on the inside of the fixing cap (220), so that a selective locking or unlocking operation can be performed according to the rotation of the fixing cap (220).

[0053] Preferably, the first fixing projection (215) and the second fixing projection (217) can be configured to have a predetermined length and width so that they can be in close contact with the longitudinal groove and the internal engaging groove of the fixing cap.

[0054] Also, preferably, the elastic socket portion (213) is formed to have a sloped surface (213a) that gradually changes in thickness and width from one end to the other, and is formed so as to maintain its own elasticity. It is sufficient for the sloped surface (213a) to maintain a predetermined width so as not to limit the rotation radius when the fixed cap (220) rotates left and right on its own.

[0055] Meanwhile, referring to FIGS. 5 and 6, the fixed cap (220) may be configured to include a cylindrical body (221) having an inner diameter that is open in the upper and lower directions; and an inner engaging groove (223) formed in a groove shape at one side along the inner surface of the body (221) in correspondence with a second fixing protrusion (217) protruding from one side on the outer side of the elastic socket portion (213).

[0056] Here, the internal engaging groove (223) of the fixed cap (220) operates to engage with the second securing projection (217) of the fixed member (210), and when the fixed cap (220) rotates by its own rotation, the second securing projection (217) of the fixed member (210) engages with the internal engaging groove (223) and simultaneously presses the elastic socket portion (213) inward while the sub-pole (110) engaged with the first securing projection (215) is tightly fixed, so that the boundary portion of the main pole and the sub-pole can be tightly fixed without movement by the socket-type connection of the fixed cap (220) to the fixed member (210).

[0057] In other words, when the temporary rotation of the fixed cap (220) is completed, the internal catch groove (223) of the fixed cap (220) is seated on the second seating projection (217) protruding from one end of the elastic socket portion (213), and the fixed cap (220) is configured to be able to be connected to the socket in a configuration in which the elastic socket portion (213) of the fixed member (210) is held in contact with the outer diameter of the sub-pole (120).

[0058] Fig. 7 is an enlarged example drawing showing another embodiment of Fig. 6.

[0059] The elastic socket portion (213) of the fixing member (210) is formed corresponding to the internal catch groove (223) of the above-mentioned fixing cap (220), and in the cross-sectional configuration, one side may be formed with an inclined surface (213-1a) that guides rotation when the fixing cap (220) rotates on its own, and an extended surface (213-2a) that extends from the inclined surface (213-1a) to a place where the second fixing protrusion (217) is located.

[0060] Here, when the fixed cap (220) rotates, it can be configured so that the internal catching groove (223) of the fixed cap is caught on the second fixing projection (217) while going up the inclined surface (213-1a) and coming into close contact with the extended surface (213-2a), and the elastic socket portion (213), which is an elastic body, can be configured so that it can be brought into close contact with the outer diameter of the sub-pole (120) while pressing the extended surface (213-2a). At this time, it can be provided with a configuration so that the adhesion strength of the joint portion is strengthened by the surface contact of the extended surface (213-2a).

[0061]

[0062] Hereinafter, the operational effects according to the configuration of the pole connection structure according to the present invention will be described as follows. The following description follows the structural description above.

[0063] Here, a fixing member (210), which is a pole locking device (200), may be provided in a fixed state at the end of the main pole (110), and a fixing cap (220) may be provided in a fixed state at the outer diameter of the sub pole (120).

[0064] First, the sub-pole (120) can be unfolded within the main pole (110) by holding the sub-pole (120) and pushing it up one by one while the respective length grooves (113)(123) of the sub-pole (120) overlap with each other on the main pole (110).

[0065] Next, by using a pole locking device (200) at the connection part of the main pole (110) and sub pole (120) that are spread out at an appropriate location, a fixing cap (220) can be fastened to the fixing member (210) of the pole locking device (200) in a rotating socket manner at the section where the sub pole (120) is spread out from the main pole (110) to enable locking and unlocking operations.

[0066] In other words, the main pole (110) and the sub pole (120) are provided in a state where their respective longitudinal grooves (113)(123) are closely spread out, and when the fixed cap (220) is temporarily pushed and rotated so as to be covered on the outside of the fixed member (210), the internal catch groove (223) formed on the inner diameter of the fixed cap (220) can be configured to ride up the inclined surface (213a) of the elastic socket portion (213) within the rotational progress radius, thereby pushing the elastic socket portion (213) with elasticity inward. At this time, the elastic socket portion (213) that is closely pressed toward the outer diameter where the sub pole (210) is located is configured to be further pressed so that the first fixing projection (215) that is protruded on the inside of the elastic socket portion (213) can be fixed toward the longitudinal groove (123) of the sub pole (120).

[0067] On the other hand, when the temporary rotation of the fixed cap (220) is completed, the internal catch groove (223) of the fixed cap (220) is seated on the second seating projection (217) protruding from one end of the elastic socket portion (213), and the fixed cap (220) is configured to be coupled with the socket in a configuration in which the elastic socket portion (213) of the fixed member (210) is held in close contact with the outer diameter of the sub-pole (120). In this way, it is possible to configure a configuration in which selective locking or unlocking of the sub-pole is possible in the main pole depending on the rotation of the fixed cap (220).

[0068] Here, the primary rigidity can be maintained by matching the longitudinal groove of the main pole and the longitudinal groove of the sub pole, and the secondary rigidity can be maintained by fixing with a fixing cap at the pole boundary area, thereby preventing a phenomenon such as the existing pole's folding in advance.

[0069] As described above, the pole connection structure according to the present invention can continuously maintain a joint state without shaking by having a groove-shaped joint structure between poles, and can overcome the problem of existing poles that were easily released even by a small impact through a simple assembly structure in which the poles are held and turned to fix them.

[0070] Although the present invention has been illustrated and described with reference to preferred embodiments as described above, it is not limited to the above-described embodiments, and various modifications and variations are possible within the scope equivalent to the technical idea of ​​the present invention and the scope of the patent claims to be described below by a person having ordinary skill in the art without departing from the spirit of the present invention.
