Description

  The present invention relates to a one-touch type folding tent, and in particular, a connecting body for unfolding and folding a pole is provided at the upper center of the tent, and the upper stage of the pole is hinged to the central connecting body. The present invention relates to a one-touch type folding tent that is improved so that all the poles are unfolded and bent at the same time.

  Generally, a tent consists of a cloth connecting the bottom, side and top, and a pole for maintaining them in a specific form. Tents are widely used as equipment to sleep during leisure activities such as camping, mountain climbing, and fishing, to avoid wind and rain, and to avoid sunlight.

  Such tents are classified into various forms according to the pattern of the installed state, the folding method, the frame structure, and the like. Recently, the use of one-touch folding tents with improved convenience has increased.

  One-touch folding tents are also called umbrella tents, Korean utility model registration No. 20-315843 (automatic tent using snap-through), utility model registration No. 20-317335 (one-touch with removable bottom cloth) Type tent).

  In the conventional one-touch folding tent described above, when looking at the folding structure of the main pole, a plurality of frame poles are concentrically connected to one connecting body located in the center of the roof, and below the inside Has a plurality of auxiliary poles for supporting and pushing up each frame pole.

  However, since the conventional tent has a structure in which the frame pole and the auxiliary pole are used to support and push up the umbrella, there are many bent portions, which causes many failures at the bending points and heavy weight. In order for the tent to maintain a constant dome shape and be firmly supported, the pole must be arcuate and appropriately curved. However, in the conventional one-touch tent, a certain height must be guaranteed from the connecting body to the connecting portion of the auxiliary pole below it. Therefore, there is a disadvantage that a space for sufficiently bending the pole in an arc shape is insufficient and the pole cannot be sufficiently bent in a desired arc shape.

  Therefore, the tent cloth cannot always maintain a tense state.

  When the tent cloth is in a loose state, it receives a lot of wind resistance, and as a result, it tends to fluctuate.

  A conventional one-touch tent has a connecting body that realizes one-touch, but there are many practical problems because it is difficult or troublesome to operate the connecting body.

  In the conventional one-touch tent, the pole can be unfolded or bent by operating the coupling body at the center. Therefore, it is impossible to increase the scale of the tent in order to easily operate the central portion. In other words, when the tent is made large, it is too high and too far to operate the central connection body at the upper center at the edge of the tent, so that the desired operation is almost impossible.

  On the other hand, in the conventional one-touch type folding tent, the pole has the following disadvantages in its joint portion.

  The conventional pole bending structure includes Korean utility model registration application No. 1988-0014238 (a device for preventing lower joint bending in a one-touch dome-shaped tent), Korean utility model registration application No. 1991-0004601 (one-touch type dome shape). Disclosed in a device for preventing bending of a lower joint of a tent.

  In the conventional bending apparatus, in the former case, the upper joint portion and the lower joint portion are connected by a hinge pin, and a spring for pushing the hinge pin is built into the hinge hole formed by a long hole. Here, since the spring is small in size, the force for pushing the pole is not sufficient. Therefore, not only the function cannot be satisfied, but also the manufacture is not easy.

  In the latter case, the upper joint and the lower joint are connected by a hinge pin, and a locking projection is formed in the elongated hinge hole. A spring is provided between the pole and the lower joint, and a support ring for supporting the spring is provided.

  However, in the above-described structure, the lower joint portion must be controlled so as to exit the range of the locking protrusion while moving in the longitudinal direction along the long hole. Therefore, the operation is not easy and the components for supporting the spring are complicated, so that the productivity is lowered and the manufacturing cost is increased.

  In addition, as one of the problems inherent to the folding pole, there is a case where the tent cloth is caught when the joint portion is deployed. Therefore, the tent cloth may be damaged and the life may be shortened.

  In addition, when the folding pole is folded vertically, the tent cloth ring may fall along the length of the pole and gather downward. When such a phenomenon occurs, it is difficult to unfold the pole when trying to expand the tent (pole) again.

  Accordingly, an object of the present invention is to provide a one-touch type folding tent that can solve the problems of the prior art.

  Another object of the present invention is to connect a plurality of frame poles to a central coupling body provided at the center of the roof, and to operate all the poles by operating the pressing plate in a state where the upper stage of the frame pole is coupled to the central coupling body. An object of the present invention is to provide a one-touch type folding tent that can be expanded or folded at the same time.

  Another object of the present invention is to provide a one-touch type folding tent which can be unfolded in a state where the tent cloth is always tensioned so that the spread pole can be bent in an appropriate arc shape.

  Another object of the present invention is to provide a one-touch folding tent that can maintain an appropriate curved state when the tent is stretched by omitting an umbrella-shaped auxiliary pole as in the present invention. There is to do.

  Furthermore, another object of the present invention is to improve the structure of the joint portion of the pole so that it can be more easily assembled and operated, and it is possible to provide convenience in use by quickly performing the folding operation of the tent. It is to provide a folding tent of the type.

  Here, the pulling rope 140 also applies a pulling force so as to prevent the separation of the pressing support member 110 and the connection support member 120 in a normal state, and the pole pulled primary by the pulling rope is further pushed down so that it can be spread well. For this reason, it is preferable to make a strong, high-quality elastic cord with elasticity.

  When the assembly of the central coupling body 100A and the frame pole 200 is completed in the manner described above, the tent is completed by hanging the rings 310 of the tent cloth 300 on the frame pole 200.

  First, as shown in FIG. 7, the upper joint part 240 includes a joint support part 241 and a joint diffraction part 242, and the upper joint part 240 is connected by a hinge pin P so as to be bent. Here, the joint is pressed by the joint spring 243 so that the joint is always expanded.

  Therefore, when the pole is bent, the joint can be bent by the user's force, and when the tent is used, the joint is automatically expanded by the force of the joint spring 243.

  As shown in FIG. 8, the lower joint portion 230 includes a pole support portion 231 and a pole diffraction portion 232.

  That is, the lower joint portion 230 includes a long hole 232b in the longitudinal direction and a hinge protrusion 232a on one side of the outer peripheral surface, and a pole diffractive portion 232 into which an end of one pole member 220 is inserted, and the pole diffractive portion. 232 has a semi-cylindrical portion 231a so that a part of 232 can be surrounded, and a pole support portion 231 inserted into the upper stage of another pole member 220, and long while penetrating the semi-cylindrical portion 232a laterally.

  In order to bend the lower joint 230, in the state shown in the upper part of FIG. 8, the pole diffractive part 232 is pulled in the longitudinal direction by the leaf spring 233 as shown below, and the hinge pin P is moved in front of the long hole 232b. To position. Next, the pole member is rotated along the arrow as indicated by a virtual line below.

  Conversely, when the pole 200 is expanded, the pole diffractive portion 232 moves downward due to its own weight, and at this time, the hinge pin P is positioned at the rear portion of the long hole 232b to prevent rotation.

  Further, as shown in FIGS. 9 and 10, an insertion member 234 having a square locking projection 234a is provided at the lower stage of the pole 200 of the present invention. The square bottom of the tent cloth 300 is connected to the support member 235 using the support band 236.

  The support member 235 has a pack hole 235a for inserting the pack 237 on the outer side, a square locking hole 235b for inserting the insertion member 234, and a band hole 235C for connecting the support band 236 continuously.

  At this time, an engagement piece 235d that is slightly curved inward is formed below the square locking hole 235b to prevent the pole from being pulled out, and the pole is maintained in a desired direction because the hole is square. It is possible.

  On the other hand, as shown in FIGS. 11 to 13, the pole 200 of the present invention can be made to further include a joint protection band 250 at the upper and lower joints 240 and 230.

  For example, when viewed from the lower joint portion 230, the joint portion includes a pole support portion 231 provided at the tip portion of one pole, a pole diffraction portion 232 provided at the tip portion of the other pole, and these. It is comprised from the hinge pin P to connect. Further, a protective band 250 having a predetermined width is provided so as to surround the upper joint portion 230 of the pole. A connecting hole 251 is formed at the upper part on both sides of the protective band 250. After the hinge pin P is inserted into the connection hole 251, the protective band is connected to the upper joint with a rivet.

  At this time, the protective band 250 is made of a flexible resin material, a woven material, or a synthetic material thereof.

  As shown in FIG. 11, a band portion 252 having a Velcro fastener (registered trademark) (or rope) is provided at an end portion extending from one end of the protective band 250. When the band portion 252 is fitted on the pole member 220, the protective band can be stably fixed to the pole.

  FIG. 12 shows the usage state of the protective band 250.

  An intermediate portion of the binding string 253 is inserted on the surface of one side of the protective band 250, and a support string 320 is provided on the tent cloth 300 where the protective band 250 is located. Therefore, when the protective band 250 is used, it is preferable to bind these strings together as shown in FIG.

  When the binding string 253 and the support string 320 are bound in this way, even if the pole joint portion 230 is bent, the binding string 253 and the support string 320 support the tent cloth. The tent cloth 300 is prevented from tilting downward. In addition, since the tent cloth 300 does not tilt downward, it does not get in the way when the tent is used thereafter.

  Next, an operation process of the tent according to the first embodiment of the present invention will be described with reference to the accompanying drawings.

  First, the state where the tent is extended will be described. When the plurality of frame poles 200 connected to the central connecting body 100A are spread by the pressing operation of the pressing support 110, they are all bent in a bow shape and the tent cloth 300 suspended inward is tensioned as shown in FIG. It is spread in the state. On the contrary, when the joint portions of the frame pole 200 are bent at the same time by the release operation of the pressing support 110, the tent is folded.

  At this time, an important operation of the coupling body 100A will be described with reference to FIGS.

  Since the hinge shaft portion 212 of the molding portion 210 is coupled to the hinge shaft support protrusion 125 of the pole support portion 128 by the pin P, the frame pole 200 maintains a state in which the traction rope insertion groove 211 side is slightly pushed upward in normal times. is doing. In this state, the traction rope 130 is maintained in the traction rope insertion groove 211, and the pressing support 110 is pressed in the vertical direction by the pole 200.

  As a result, in the pressed shaft portion 111 of the pressing support tool 110, the locking projection 113 at the lower edge thereof is exposed downward from the vertical through hole 122 of the connection support tool 120. In this state, the pressing support 110 is rotated clockwise.

  When the shaft portion 111 of the pressing support 110 rotates in this way, the locking projection 113 at the lower edge portion is locked to the rotation positioning projection 126 on the lower surface of the vertical tube portion 121 and rotation is prevented. At this time, the upper plate 115 pushes down the upper stage of the frame pole 200, and the frame pole 200 pressed on the upper stage is pushed up to the maximum with the hinge shaft portion 212 as a fulcrum, so that it expands in a bowed state, The tent cloth 300 is spread.

When the tent is to be folded, the upper plate 115 of the pressing support 110 is pushed down and rotated counterclockwise.
When the shaft portion 111 of the pressing support 110 rotates counterclockwise, the locking projection 113 projecting from the lower edge thereof is fitted into the vertical groove 123 of the vertical through hole 122. Therefore, the entire pressing support 110 is easily raised by the force that pushes up the tip of the frame pole 200, and the tension of the frame pole 200 can be released. Next, when the joint portions 230 and 240 are bent, the tent cloth 300 can be easily folded.

In other words, the one-touch type folding tent according to the first embodiment is configured such that the central coupling body for pole coupling is constituted by the coupling support and the pressing support, and the hinge shaft support protrusion of the coupling support is used as the hinge shaft portion of the frame pole. In the assembled state, all the frame poles arranged radially can be expanded and bent at the same time by only a simple operation of pushing the pressing support. Therefore, the entire tent can be folded more easily with a one-touch method.
(Second Embodiment)
FIG. 14 is an exploded perspective view of a connecting body according to a second embodiment of the present invention, FIG. 15 is a cross-sectional view showing a developed state of a pole of the connecting body according to the second embodiment of the present invention, and FIG. It is sectional drawing which shows the process in which the pole of the coupling body which concerns on 2nd Embodiment of this invention is bent.

  As shown in FIG. 14, the central coupling body 100B according to the second embodiment of the present invention includes a coupling support 120 in which tips of radially arranged poles are pivotally coupled by hinges, and this coupling. And a pressing support 110 that presses down an upper stage of the pole connected to the support 120.

  In other words, the pressing support 110 has an upper plate 115 having a plurality of pulling rope holes 112 formed in the center, and extends vertically downward from the lower surface of the upper plate 115, and a plurality of locking projections 113 radially formed on the lower edge portion. It comprises a protruding shaft portion 111.

  The connection support 120 includes a vertical pipe part 121 having a vertical through hole 122 into which the shaft part 111 of the pressing support 110 is inserted, and a plurality of rotational positioning protrusions 126 protruding below the vertical pipe part 121. The plurality of rotation guide grooves 129 formed radially on the upper surface of the vertical pipe portion 121 and the plurality of hinge shaft support protrusions 125 formed on the side surface of the support tool corresponding to each rotation guide groove.

  Then, the tension rope 140 is inserted into the tension rope hole 112 and the plurality of tension rope holes formed in the lower lower plate 114 corresponding to the hole, and the pressing support 110 and the connection support 120 are bound. To avoid separation from each other.

  Here, the frame pole 200 and the upper joint portion and the lower joint portion provided on the frame pole are the same as those described in the first embodiment.

  However, the upper stage portion of the frame pole for connecting the expansion spring 214 has a different configuration as shown in FIG.

  That is, the frame pole 200 described above is rotatably connected to the pole connection support by the molding part 210 provided at one end of the pole member 220.

  The molding part 210 provided at the tip of the pole member has a spring insertion part 213 and a hinge shaft part 212 on its lower surface. One end of the expansion spring 214 is inserted into the spring insertion part 213 of the molding part 210, and an annular part 214a into which the pin P is inserted is formed in the middle. Therefore, when the expansion spring 214 is elastically mounted on the hinge shaft support protrusion 125 together with the hinge shaft portion 212 by the pin P inserted into the ring portion 214a, the expansion spring 214 presses the pole 200 upward.

  Next, an assembly structure of the central connector 100B and the frame pole 200 according to the second embodiment of the present invention will be described.

  First, the frame poles 200 are radially inserted into the respective rotation guide grooves 129 formed on the upper surface of the connection support 120. At this time, when the ring portion 214a of the expansion spring 214 is attached together to the hinge shaft portion 212 provided in the pole molding portion 210 and this portion is attached to the hinge shaft support protrusion 125, the pin P is inserted. The spring is assembled to the connecting support by a spring.

  Thereafter, the shaft 111 of the pressing support 110 is inserted into the vertical through-hole 122 formed at the center of the vertical pipe 121 of the connection support 120 and assembled.

After the shaft part is completely engaged, the tension rope 140 is inserted into the tension rope hole 112 drilled vertically and the tension rope hole of the lower plate 114 disposed on the lower side of the shaft part 111 to press the support And tie the connecting support.

  The pulling rope 140 also applies a pulling force so as to prevent the separation of the pressing support member 110 and the connection support member 120 in the normal state, and further pushes down the primary pulling pole by the pulling rope so that it is well spread. For this reason, it is preferable to make it from a strong, high-quality rubber string having elasticity.

  When the assembly of the central coupling body 100B and the frame pole 200 is completed in the manner as described above, the ring 310 of the tent cloth 300 is engaged with the frame pole 200 at various places to complete the tent.

  As shown in FIG. 18, the tension rope 140 according to the second embodiment of the present invention can be replaced with a tension coil spring 140a. In this case, instead of the pressing tension rope hole 112 of the upper plate 115, a through hole is formed inside the pressing support, and a coil spring 140a is provided in the through hole. At this time, the upper stage of the coil spring is connected to an engagement washer 114 b disposed on the upper plate, and the lower stage is connected to an engagement ring 114 a formed on the lower plate 114.

  The tent according to the second embodiment of the present invention configured as described above can be expanded and bent by the same method as in the first embodiment.

The lowered tent cloth 300 is spread in a tensioned state. Conversely, when the plurality of frame poles are bent by the release operation of the pressing support 110, the joints of the frame pole 200 are simultaneously bent and the tent is folded.

  Next, with reference to FIG. 16, the operation | movement of the important center coupling body 100B of this invention is demonstrated.

  FIG. 16 is a cross-sectional view illustrating a process of bending a pole of a connector according to the second embodiment of the present invention.

  Since the pin P maintains the state where the hinge shaft portion 212 of the molding portion 210 is coupled to the hinge shaft support protrusion 125 together with the expansion spring 214, the frame pole 200 is supported by the force of the expansion spring in a normal state. The tool 110 is pressed in the vertical direction.

  The shaft portion 111 of the pressing support tool 110 to be pressed has a lower locking projection 113 exposed downward from the vertical through hole 122 of the connection support tool 120, and in the exposed state, the pressing support tool 110 is moved clockwise. Rotate.

  When the shaft portion 111 of the pressing support 110 rotates in this way, the locking projection 113 projecting from the lower edge of the pressing support 110 is locked to the rotation positioning projection 126 on the lower surface of the vertical pipe portion 121 to prevent rotation. . At this time, the upper plate 115 presses the upper stage of the frame pole 200 described above to the maximum. The frame pole 200 whose upper stage is pressed is pushed up by the force of the expansion spring 214 to the maximum with the hinge shaft portion 212 as a fulcrum, so that the tent cloth 300 is unfolded while being unfolded in an arcuate shape.

  At this time, when the tent is to be folded, the upper plate 115 of the pressing support 110 described above is pushed down and rotated counterclockwise.

  When the shaft portion 111 of the pressing support 110 rotates counterclockwise, the locking projection 113 projecting from the lower edge thereof is aligned with the vertical groove 123 of the vertical through hole 122. In this state, when the pulling rope 140 is loosened, a force for pushing up the tip of the frame pole 200 is generated.

  Therefore, the entire pressing support 110 is easily raised by this force.

  Therefore, since the tension of the frame pole 200 is released, the tent cloth 300 can be easily folded when the joint portions 230 and 240 are bent.

In the one-touch type folding tent according to the second embodiment of the present invention, the central coupling body for coupling the poles is composed of the coupling support and the pressing support, and the hinge shaft portion of the frame pole is the hinge shaft of the coupling support. All frame poles arranged radially can be expanded and bent at the same time by a simple operation of pushing and rotating the pressing support in the assembled state with the supporting protrusions. Therefore, the entire tent can be folded more easily with a one-touch type.
(Third embodiment)
Next, a third embodiment of the present invention will be described.

  FIG. 19 is an exploded perspective view of a connecting body according to the third embodiment of the present invention, FIG. 20 is a cross-sectional view showing a developed state of the pole of the connecting body according to the third embodiment of the present invention, and FIG. It is sectional drawing which shows the process in which the pole of the coupling body which concerns on 3rd Embodiment of this invention is bent.

  As in the first and second embodiments, the third embodiment of the present invention includes a plurality of frame poles 200 that extend radially to maintain the overall shape of the tent, and the poles are connected to the central coupling body 100C. By using and connecting, it is possible to bend at the same time.

  At this time, as shown in FIG. 20, the central coupling body 100C of the third embodiment of the present invention is a coupling support that rotatably supports the radially arranged poles via the hinge shaft portion at the tip thereof. It comprises a tool 160, a pressing plate 150 for pressing down the upper stage portion of the pole supported by the connection support tool 160, and a lifting member 170 for guiding the operation of the pressing plate 150.

  The support 160 of the central coupling body 100C includes a pole hinge support 165 formed on the periphery of the four sides for coupling the pole 200, a support plate portion 161 having a locking hole 161a in the center, and the support plate portion. The tube portion 162 extends downward.

  In addition, one end of the central coupling body disposed at the upper portion of the support plate portion 161 is inserted into the coupling hole 151 formed in the pressing plate 150 by the pin 153, and the intermediate portion is engaged with the locking hole 161a of the support. It includes a mounting member 152 formed with a locking projection 152a so as to stop, and an expansion elastic body 154 that presses and expands the lower part of the mounting member.

  The elevating member 170 moves up and down along a central screw rod 171 suspended from the central portion of the pressing plate, and an elevating disc 174 elastically provided in the tubular body portion 162 of the support by a compression spring 172. And a release member 173 that can move up and down while being guided by an extension 173c inserted in the through hole 174a of the elevating disk.

  In addition, the release member 173 has one upper part 173a and a lower half part 173b that are joined together. That is, the release member 173 is assembled by a method in which the extension portion 173 c is inserted into the through hole 174 a of the elevating disk 174. The release member 173 is configured to push the locking protrusion 152a of the mounting member 152 regardless of the elevation of the elevation disk 174 provided by the compression spring 172.

  Here, the central screw rod 171 includes a stopper nut 171a for restricting the height of the mounting member 152 at the intermediate portion thereof. The lifting member 170 includes an auxiliary connecting wire 175 for easily connecting the center of the tent cloth to the bottom surface.

  The auxiliary connecting wire 175 is configured such that the elevating member 170 is easily pulled and lowered in a state where the elevating member 170 is kept horizontal in the tubular body portion 162 of the support 160.

  On the other hand, the configuration of the frame pole 200 and the upper joint 230 and the lower joint 240 of the pole are the same as those described in the first embodiment of the present invention.

  And as shown in FIG. 17, the structure for connecting the upper stage of the expansion spring 214 is the same as that of 2nd Embodiment of this invention.

  That is, the frame pole 200 is rotatably connected to the connection support by the molding part 210 provided on the upper stage of the pole member 220.

  The molding part 210 provided at the tip of the pole member has a spring insertion part 213 and a hinge shaft part 212 on its lower surface. One end of the expansion spring 214 is inserted into the spring insertion portion 213 of the molding portion, and an annular portion 214a into which the pin P is inserted is formed in the middle. Therefore, when the expansion spring 214 is elastically mounted on the hinge shaft support protrusion 125 together with the hinge shaft portion 212 by the pin P inserted into the ring portion 214a, the expansion spring 214 presses the pole 200 upward.

  Next, the operation state of the central connector 100C and the frame pole 200 according to the present invention will be described with reference to the accompanying drawings.

  FIG. 20 shows a state in which the tent is expanded while the central link body 100C according to the present invention pushes down the upper stage of the frame pole 200 to expand the pole.

  At this time, if the tent is to be folded, the release member 173 of the lifting member 170 described above may be struck upward inside (or outside) the tent.

  When operated in this way, the elevating member 170 to which the release member 173 is fixed is pushed upward against the force of the compression spring 172, and the upper stage 170 a pushes the locking projection 152 a of the mounting member 152. It becomes like this.

  Therefore, the pole 200 rotates about the hinge support 165 as a fulcrum by its own weight while the lower stage of the locking projection 152a of the mounting member 152 rotates inward as indicated by a virtual line. Accordingly, as shown in FIG. 21, the pole 200 can fold the tent cloth while standing vertically alongside the central screw rod 171.

  Conversely, when the tent is to be expanded, the auxiliary connecting wire 175 of the elevating member 170 described above is pulled inside (or outside) the tent.

  When the auxiliary connecting wire 175 is pulled, the pressing plate 150 connected to the central screw rod 171 is lowered while the release member 173 of the elevating member 170 is lowered.

  In the mounting member 152 provided on the pressing plate 150, the locking protrusion 152a formed at the intermediate portion thereof is expanded by the expansion elastic body 154, and a pressing force can be generated outward. Thereby, the locking projection 152a is locked to the inner peripheral edge of the locking hole 161a of the support 160, and the locked state is maintained.

  Accordingly, as shown in FIG. 20, each pole 200 is rotated about the hinge support 165 and is pushed up horizontally, and the tent cloth suspended from the pole 200 can be widely spread.

  The pressing plate 150 and the elevating member 170 according to the third embodiment of the present invention can be implemented with a partially improved structure as shown in FIGS.

  22 includes a support bar portion 155 that extends downward from the center of the bottom surface thereof. When this support bar portion is inserted into the center of the support 160, it can be prevented from swinging left and right.

  A vertical groove 155a for the mounting member 152 is formed in the vertical direction around the support bar portion 155 to prevent unnecessary movement of the mounting member 152.

  In the elevating member 170 of FIG. 22, instead of omitting the lower cylindrical portion of the release member 173 that is difficult to assemble, a new expanded elastic body 154 that operates accurately is provided at the upper central portion of the elevating disc 174. The lower part of the release member 173 is configured to be pressed by a pressing member 177 provided at the center of the ceiling of the tent cloth 300.

  22 to 24, reference numeral 156 is a lid for appearance, and 176 is a washer for binding the auxiliary connecting wire 175 while fixing the expansion elastic body 154.

  The one-touch type folding tent shown in the third embodiment of the present invention is designed to fold by operating the inside or outside of this tent and the central upper step, so that the tent is manufactured or operated in a large size. The operation is easy even when the person is short. In other words, even when the tent is large or the user is short, the pole can be unfolded or bent from the central connection by simply pulling it down in the center of the tent, or simply pushing up the ceiling.
