Description

BACKGROUND OF THE INVENTION1. Field of the Invention

[0001] The present technology relates to a foldable tent frame having a novel locking device, capable of enabling a tent frame to be folded and unfolded with a simple operation while preventing a fixing force from being decreased by long-term use.2. Description of the Related Art

[0002] Recently, the use of folding tents that are easily moved, installed, and stored has been gradually increasing.

[0003] Such folding tents basically include a tent frame, and an awning covered on a polygonal frame structure formed by deploying the tent frame so as to provide a sunshade function.

[0004] In addition, the folding tent frame is configured such that scissor arms are arranged between pillars, in which an upper end of the scissor arm is fixed to an upper portion of the pillar through a fixing bracket, and a lower end of each of the scissor arms is fixed through a movable bracket that slides on the pillar.

[0005] Therefore, when an operator deploys the scissor arm formed between the pillars, the polygonal frame structure on which the awning is covered may be formed, and when folding (foldable) of the scissor arm formed between the pillars is performed, a volume may be reduced to ensure portability and ease of storage.

[0006] For example, as shown in FIGS. 1 and 2, a conventional frame structure may include a reference structure 11 provided at an uppermost portion of a pole member 10 having a foldable structure, and a steel rod 13 extending downward from a lower portion of the reference structure 11.

[0007] In addition, a handle lock 15 lifted and lowered according to folding and unfolding of the pole member 10 may be provided in the lower portion of the reference structure 11. When the handle lock 15 is lifted so that the steel rod 13 is inserted into the handle lock 15, the pole member 10 may be fixed in an unfolded state, and when the handle lock 15 is lowered so that the steel rod 13 is separated from the handle lock 15, the pole member 10 may be freely folded for storage.

[0008] In addition, although not shown, fixation and release may be enabled by a switch (not shown) provided on the reference structure 11 or the like while the steel rod 13 is inserted into the handle lock 15.

[0009] Meanwhile, the frame structure that is fixed or released according to an insertion state of the steel rod has a problem in that a fixing force between the handle lock and the steel rod is reduced when loosening is caused by long-term use.

[0010] In addition, the conventional frame structure has inconvenience of additional complexity since the conventional frame structure satisfies a structure that may be fixed or released by additionally operating the switch while the steel rod is inserted into the handle lock.Documents of Related ArtPatent Documents

[0034] Hereinafter, a foldable tent frame having a novel locking device (hereinafter simply referred to as a 'tent frame') according to the present invention will be described in detail with reference to the accompanying drawings.

[0035] Before the description, an unillustrated awning (not shown) may be provided on an outer surface of a pole member 100 that will be described below so as to satisfy the purpose of a tent. In order to clearly convey the gist of a tent frame 1 according to the present invention, the description will be made below through drawings in which the awning is omitted.

[0036] In addition, it is to be noted that the reference numeral '200' that is not shown in the drawings refers to a locking device 200 including a lock clip 210, a slider 240, and one of a first finger lock 220 or a second finger lock 230, which will be described below.

[0037] First, as shown in FIG. 3, the tent frame 1 according to the present invention may largely include a pole member 100 and a locking device 200.

[0038] In more detail, according to the present invention, the pole member 100 may include a handle lock 110, a reference structure 120, an upper loop pole 130, a lower loop pole 140, a support pole 150, and a support frame 160.

[0039] For example, as shown in FIGS. 4 and 5, the handle lock 110 may include a plurality of rotation grooves H4 formed in an upper portion of the handle lock 110 so that a plurality of first support poles 151 may be rotatably coupled to the rotation grooves H4, and the handle lock 110 may be located in a lower portion of the reference structure 120.

[0040] The handle lock 110 may be supported by the first support poles 151 so as to be lifted and lowered by an external force of a user or the like, and may generate power for unfolding or folding a plurality of upper loop poles 130 through the lifting and lowering.

[0041] In addition, as shown in the drawings, the reference structure 120 may be located in an upper portion of the handle lock 110, and may include a plurality of rotation grooves H4 formed in a lower portion of the reference structure 120 so that the upper loop poles 130 may be rotatably coupled to the rotation grooves H4.

[0042] In addition, as shown in the drawings, a total of four upper loop poles 130 may be provided to have a bar shape according to the present invention, and the lock clip 210 that will be described below may be fixedly inserted around an outer surface of each of the upper loop poles 130.

[0043] Each of the upper loop poles 130 may have one side rotatably coupled to the rotation groove H4 formed in the reference structure 120, and an opposite side rotatably inserted into the first finger lock 220 that will be described below or fixedly inserted into the second finger lock 230 that will be described below.

[0044] In addition, a plurality of lower loop poles 140 having may be provided to have the same bar shape as the upper loop poles 130 described above with only a different length as compared to the upper loop pole 130.

[0045] Each of the lower loop poles 140 may have one side rotatably coupled to the first finger lock 220 or the upper loop pole 130, and an opposite side rotatably coupled to the support frame 160, so that power for pulling or pushing the support frame 160 toward the handle lock 110 according to the unfolding or folding of the upper loop pole 130 may be transmitted.

[0046] For ease of the power transmission, according to the present invention, the pole member 100 may use a support pole 150 including first to third support poles 151, 152, and 153, which may be viewed in detail through FIG. 3.

[0047] In this case, each of the first support poles 151 rotatably coupled to the rotation groove H4 of the handle lock 110, may have an opposite side rotatably coupled to an outer surface of the upper loop pole 130 on which the lock clip 210 that will be described below is mounted.

[0048] In particular, each of second support poles 152 may satisfy a structure having one side rotatably coupled to an outer surface of the slider 240 through which the lower loop pole 140 is inserted such that the slider 240 may slidably move on an outer surface of the lower loop pole 140, and an opposite side rotatably coupled to the third support pole 153.

[0049] In addition, as shown in the drawings, a plurality of third support poles 153 may be installed to have an 'X' shape between each other so as to allow a pair of adjacent support frames 160 to be connected to each other so that a distance between the support frames 160 may be narrowed or widened, thereby satisfying a foldable structure.

[0050] To this end, each of the support frames 160 may have a function of a leg so that the tent frame 1 according to the present invention may be supported on a ground surface.

[0051] In addition, the locking device 200 may be a component for maintaining a state of the pole member 100 that is unfolded by the lifting of the handle lock 110 described above, and may include one of the first finger lock 220 or the second finger lock 230 in addition to the lock clip 210 and the slider 240.

[0052] For example, as shown in FIGS. 6 and 7, the lock clip 210 may include a through-hole H1 through which the upper loop pole 130 is inserted, and a fitting groove H2 formed adjacent to the through-hole H1 and to which the first support pole 151 is detachably coupled.

[0053] A cutout part through which the first support pole 151 enters and exits may be formed in an outer surface of the fitting groove H2.

[0054] In this case, preferably, as shown in the drawings, a center point P1 of the through-hole H1 and a center point P2 of the fitting groove H2, which are formed in the lock clip 210, may be formed in the lock clip 210 so as to be connected in an oblique line.

[0055] In addition, as shown in FIGS. 8 and 9, the slider 240 may include a through-hole H1 formed through an outer surface of the slider 240 and through which the lower loop pole 140 is inserted, and a pair of second support poles 152 may be rotatably mounted on both sides of the slider 240.

[0056] In this case, preferably, a diameter of the through-hole H1 may be larger than a diameter of the lower loop pole 140 so that the slider 240 may slidably move in a longitudinal direction of the lower loop pole 140 inserted through the slider 240.

[0057] In addition, the first finger lock 220 and the second finger lock 230 may be components for fixing or releasing the slider 240 that moves along the lower loop pole 140 by the lifting and lowering of the handle lock 110, and according to the present invention, one of the first finger lock 220 or the second finger lock 230 may be applied for use.

[0058] In this case, as shown in FIGS. 9 and 10, a fitting groove H2 including a partition wall 222 formed inside the fitting groove H2 may be formed in an outer surface of the first finger lock 220 so that the upper loop pole 130 and the lower loop pole 140 may be coupled to the first finger lock 220 so as to rotate in a divided region with the partition wall 222 interposed therebetween.

[0059] In this case, preferably, a first hook 221 may extend from a lower outer surface of the first finger lock 220 toward the lower loop pole 140 so that the slider 240 that slidably moves along the lower loop pole 140 may be fixed to or released from first hook 221.

[0060] In other words, when the handle lock 110 is lifted so that the upper loop pole 130 and the lower loop pole 140 form a straight line within the fitting groove H2 based on the partition wall 222, the slider 240 may be guided by the pair of second support poles 152 so as to slidably move toward the first finger lock 220, so that the first finger lock 220 may be fitted and coupled to a bottom surface of the slider 240 by the first hook 221.

[0061] To this end, an extension length of the first hook 221 may be configured to allow the first hook 221 to be fitted and coupled to a lower portion of the slider 240 through shape matching, which may also be similarly applied to the second hook 231 formed on the second finger lock 230 that will be described below.

[0062] Meanwhile, unlike the first finger lock 220 described above, as shown in FIGS. 11 and 12, the second finger lock 230 may include: an insertion hole H3 formed in an upper outer surface of the second finger lock 230, and into which the upper loop pole 130 is rotatably inserted; and a fitting groove H2 formed in an outer surface of the second finger lock 230 so as to be adjacent to the insertion hole H3, and to which the lower loop pole 140 is detachably fitted and coupled.

[0063] In addition, a second hook 231 may extend from a lower portion of the second finger lock 230 toward the lower loop pole 140 in the same manner as the first hook 221 described above so that the second finger lock 230 may be detachably fitted and coupled to the lower portion of the slider 240.

[0064] In this case, preferably, as shown in the drawings, the lower loop pole 140 fitted and coupled to the fitting groove H2 of the second finger lock 230 may have a structure rotatably coupled to the outer surface of the upper loop pole 130.

[0065] In detail, according to the present invention, selection may be made: the first finger lock 220 may be applied to a case of a coupling structure in which the upper loop pole 130 and the lower loop pole 140 form a straight line with each other when the handle lock 110 is lifted; and the second finger lock 230 may be applied to a case of a coupling structure in which the upper loop pole 130 and the lower loop pole 140 are in parallel with each other when the handle lock 110 is lifted.

[0066] As described above, according to the tent frame 1 of the present invention, unlike the conventional device, while the handle lock 110 is lifted in order to unfold the pole member 100, the upper loop pole 130 and the lower loop pole 140 may be fitted and coupled in an unfolded state through the fitting and coupling between the first support pole 151 and the lock clip 210 and the fitting and coupling between the first finger lock 220 or the second finger lock 230 and the slider 240 so that the pole member 100 may be stably and firmly unfolded, and while the handle lock 110 is lowered, all the fitted and coupled components may be collectively released so that the tent frame 1 may be easily and stably unfolded and folded.

[0042] In addition, as shown in the drawings, a total of four upper loop poles 130 may be provided to have a bar shape according to the present invention, and the lock clip 210 that will be described below may be fixedly inserted around an outer surface of each of the upper loop poles 130.

[0043] Each of the upper loop poles 130 may have one side rotatably coupled to the rotation groove H4 formed in the reference structure 120, and an opposite side rotatably inserted into the first finger lock 220 that will be described below or fixedly inserted into the second finger lock 230 that will be described below.

[0044] In addition, a plurality of lower loop poles 140 having may be provided to have the same bar shape as the upper loop poles 130 described above with only a different length as compared to the upper loop pole 130.

[0045] Each of the lower loop poles 140 may have one side rotatably coupled to the first finger lock 220 or the upper loop pole 130, and an opposite side rotatably coupled to the support frame 160, so that power for pulling or pushing the support frame 160 toward the handle lock 110 according to the unfolding or folding of the upper loop pole 130 may be transmitted.

[0046] For ease of the power transmission, according to the present invention, the pole member 100 may use a support pole 150 including first to third support poles 151, 152, and 153, which may be viewed in detail through FIG. 3.

[0047] In this case, each of the first support poles 151 rotatably coupled to the rotation groove H4 of the handle lock 110, may have an opposite side rotatably coupled to an outer surface of the upper loop pole 130 on which the lock clip 210 that will be described below is mounted.

[0048] In particular, each of second support poles 152 may satisfy a structure having one side rotatably coupled to an outer surface of the slider 240 through which the lower loop pole 140 is inserted such that the slider 240 may slidably move on an outer surface of the lower loop pole 140, and an opposite side rotatably coupled to the third support pole 153.

[0049] In addition, as shown in the drawings, a plurality of third support poles 153 may be installed to have an 'X' shape between each other so as to allow a pair of adjacent support frames 160 to be connected to each other so that a distance between the support frames 160 may be narrowed or widened, thereby satisfying a foldable structure.

[0050] To this end, each of the support frames 160 may have a function of a leg so that the tent frame 1 according to the present invention may be supported on a ground surface.

[0051] In addition, the locking device 200 may be a component for maintaining a state of the pole member 100 that is unfolded by the lifting of the handle lock 110 described above, and may include one of the first finger lock 220 or the second finger lock 230 in addition to the lock clip 210 and the slider 240.

[0052] For example, as shown in FIGS. 6 and 7, the lock clip 210 may include a through-hole H1 through which the upper loop pole 130 is inserted, and a fitting groove H2 formed adjacent to the through-hole H1 and to which the first support pole 151 is detachably coupled.

[0053] A cutout part through which the first support pole 151 enters and exits may be formed in an outer surface of the fitting groove H2.

[0054] In this case, preferably, as shown in the drawings, a center point P1 of the through-hole H1 and a center point P2 of the fitting groove H2, which are formed in the lock clip 210, may be formed in the lock clip 210 so as to be connected in an oblique line.

[0055] In addition, as shown in FIGS. 8 and 9, the slider 240 may include a through-hole H1 formed through an outer surface of the slider 240 and through which the lower loop pole 140 is inserted, and a pair of second support poles 152 may be rotatably mounted on both sides of the slider 240.

[0056] In this case, preferably, a diameter of the through-hole H1 may be larger than a diameter of the lower loop pole 140 so that the slider 240 may slidably move in a longitudinal direction of the lower loop pole 140 inserted through the slider 240.

[0057] In addition, the first finger lock 220 and the second finger lock 230 may be components for fixing or releasing the slider 240 that moves along the lower loop pole 140 by the lifting and lowering of the handle lock 110, and according to the present invention, one of the first finger lock 220 or the second finger lock 230 may be applied for use.

[0058] In this case, as shown in FIGS. 9 and 10, a fitting groove H2 including a partition wall 222 formed inside the fitting groove H2 may be formed in an outer surface of the first finger lock 220 so that the upper loop pole 130 and the lower loop pole 140 may be coupled to the first finger lock 220 so as to rotate in a divided region with the partition wall 222 interposed therebetween.

[0059] In this case, preferably, a first hook 221 may extend from a lower outer surface of the first finger lock 220 toward the lower loop pole 140 so that the slider 240 that slidably moves along the lower loop pole 140 may be fixed to or released from first hook 221.

[0060] In other words, when the handle lock 110 is lifted so that the upper loop pole 130 and the lower loop pole 140 form a straight line within the fitting groove H2 based on the partition wall 222, the slider 240 may be guided by the pair of second support poles 152 so as to slidably move toward the first finger lock 220, so that the first finger lock 220 may be fitted and coupled to a bottom surface of the slider 240 by the first hook 221.

[0061] To this end, an extension length of the first hook 221 may be configured to allow the first hook 221 to be fitted and coupled to a lower portion of the slider 240 through shape matching, which may also be similarly applied to the second hook 231 formed on the second finger lock 230 that will be described below.

[0062] Meanwhile, unlike the first finger lock 220 described above, as shown in FIGS. 11 and 12, the second finger lock 230 may include: an insertion hole H3 formed in an upper outer surface of the second finger lock 230, and into which the upper loop pole 130 is rotatably inserted; and a fitting groove H2 formed in an outer surface of the second finger lock 230 so as to be adjacent to the insertion hole H3, and to which the lower loop pole 140 is detachably fitted and coupled.

[0063] In addition, a second hook 231 may extend from a lower portion of the second finger lock 230 toward the lower loop pole 140 in the same manner as the first hook 221 described above so that the second finger lock 230 may be detachably fitted and coupled to the lower portion of the slider 240.

[0064] In this case, preferably, as shown in the drawings, the lower loop pole 140 fitted and coupled to the fitting groove H2 of the second finger lock 230 may have a structure rotatably coupled to the outer surface of the upper loop pole 130.

[0065] In detail, according to the present invention, selection may be made: the first finger lock 220 may be applied to a case of a coupling structure in which the upper loop pole 130 and the lower loop pole 140 form a straight line with each other when the handle lock 110 is lifted; and the second finger lock 230 may be applied to a case of a coupling structure in which the upper loop pole 130 and the lower loop pole 140 are in parallel with each other when the handle lock 110 is lifted.

[0066] As described above, according to the tent frame 1 of the present invention, unlike the conventional device, while the handle lock 110 is lifted in order to unfold the pole member 100, the upper loop pole 130 and the lower loop pole 140 may be fitted and coupled in an unfolded state through the fitting and coupling between the first support pole 151 and the lock clip 210 and the fitting and coupling between the first finger lock 220 or the second finger lock 230 and the slider 240 so that the pole member 100 may be stably and firmly unfolded, and while the handle lock 110 is lowered, all the fitted and coupled components may be collectively released so that the tent frame 1 may be easily and stably unfolded and folded.
