The following shall further explain the utility model in detail by combining with the figures and embodiments.

As shown in FIGS. 1-3, a snap-in and support structure of tent support comprises a tube piece 1, a tube holder 2, a handle 3 and a locking sleeve 4; see a telescopic tube and a tube holder in the patent (application No.: 201520633723.5) in China listed in the background technology for the functions of the tube piece 1 and the tube holder 2 in the tent support, and the effects thereof shall not be repeated.

Through hole extending longitudinally is arranged in the middle of the tube holder, thereby forming an accommodation cavity 21 having an upper opening. In some embodiments, at least one part of the locking sleeve 4 is arranged in the accommodation cavity 21. The handle 3 is arranged under the tube holder 2 and is presented as a hollow handle with the upper opening. The accommodation cavity 21 of the tube holder 2 is arranged in the handle 3 partially.

The bottom of the tube piece 1 is provided with a first locking pin 11, a second locking pin 12, a baffle 13 and a limiting sleeve 14. In one example, the first locking pin 11 and the second locking pin 12 pass through the tube piece 1 respectively and transversely and are arranged at interval from the top to the bottom. In some embodiments, the first locking pin 11 is arranged above the second locking pin 12. In some embodiments, the baffle 13 is sleeved at the periphery of the tube piece 1 and arranged between the first locking pin 11 and the second locking pin 12. In some embodiments, the limiting sleeve 14 is sleeved at the periphery of the tube piece 1 and arranged under the baffle 13.

In one example, a limiting boss 212 extends upwards and is arranged in the middle of a bottom wall of the accommodation cavity and the bottom of the limiting sleeve 14 is arranged on the limiting boss 212. Moreover, the baffle 13, the limiting sleeve 14 and the tube piece 1 can also be formed integrally. In one example, the diameters of the baffle 13 and the limiting sleeve 14 are greater than that of the tube piece 1.

The bottom of the tube piece 1 passes through the locking sleeve 4 and extends into the handle 3 after passing through the bottom of the accommodation cavity 21 of the tube holder 2; and the bottom of the tube piece 1 extends to the place under the handle 3 along the decreasing diameter. Moreover, an end cover 5 is arranged under the handle 3 and is connected with the bottom of the tube piece 1 through the screw.

Advantageously, the first locking pin 11 is arranged in the locking sleeve 4 to cooperate with each other. In some embodiments, the second locking pin 12 is positioned in the handle 3 under the tube holder 2 and while the baffle 13 is positioned under the locking sleeve 4. Moreover, the tube piece 1 moves opposite to the tube holder 2 with certain range in the vertical direction.

A spring 6 is arranged at the periphery of the tube piece 1 and between the baffle and the bottom wall of the accommodation cavity 21. In some embodiments, an upper lug 61 of an upper boss and a lower lug 62 of a lower boss are formed on an upper end and a lower end of the spring 6, respectively. In some embodiments, the baffle 13 is provided with a first positioning hole 131, and the bottom wall of the accommodation cavity 21 is provided with a second positioning hole 211.

As shown in FIG. 5, advantageously the first positioning hole 131 twists with certain angle in the circumferential direction opposite to the second positioning hole 211. As such, the first positioning hole 131 and the second positioning hole 211 are positioned on the different vertical line. Moreover, the upper lug 61 passes through the first positioning hole 131 and the lower lug 62 passes through the second positioning hole 211; thus, the spring 6 is positioned.

As shown in FIGS. 3 and 4, two stop pieces 31 which are arranged in the circumferential direction at interval are formed at the bottom of the handle 3, preferably two stop pieces 31 are arranged symmetrically with respect to the center, and a limiting groove 32 is formed among the two stop pieces 31.

Advantageously, the second locking pin 12 runs through two ends of the tube piece 1 and are positioned in the limiting groove 32 among two stop pieces 31, respectively; the second locking pin 12 keeps the trend of propping against corresponding stop piece 31 in presence of the spring 6.

As shown in FIGS. 6 and 7, a lower part of the locking sleeve 4 is provided with bosses 41 which are arranged in the circumferential direction at interval, and the bosses are formed on an inner wall of the locking sleeve 4 after extending inward in the radial direction. The boss 41 comprises a guide inclined surface 411 ascending spirally from the bottom to the top in the circumferential direction and formed on a first side and a top surface 412.

In some embodiments, a second side of the boss 41 in the circumferential direction far from the guide inclined surface 411 is provided with a stopper 42; the stopper 42 is formed on the inner wall of the locking sleeve 4 after extending inward in the radial direction, and extends upwards from the bottom of the locking sleeve 4.

Advantageously, the smooth transition occurs between the first side of the stopper and the top surface 412 of the boss 41, and the second side of the stopper 42 is opposite to the guide inclined surface 411 of the other boss 41.

During installation, the following steps occur:

1) sleeve the spring on the tube piece 1, twist for certain degree to make it have certain pre-tightening force; then fix the two lugs of the spring 6 with the tube piece 1 and the tube holder 2 respectively; and

2) insert the tube piece 1 into the locking sleeve 4, the tube holder 2 and the handle 3, and connect with the tube piece 1 after covering an end cover 5 at the bottom of the handle 3.

Advantageously to facilitate opening, closing, and locking of the tent structure, two ends of the first locking pin 11 on the tube piece 1 are propped against the guide inclined surface 411 of the boss 41 in the locking sleeve 4 respectively, and two ends of the second locking pin 12 on the tube piece 1 are propped against the side of the stop piece 31 in the handle respectively at this time.

In some embodiments, the spring 6 shall be further compressed by pushing the handle 3 upward when the tent is unfolded. More specifically, twist the tube piece 1 opposite to the tube holder 2 and twist the spring 6 at the same time. Advantageously, the second locking pin 12 gradually moves away from the stop piece 31 propped against it originally, and the first locking pin 11 on the tube piece 1 moves upwards along the guide inclined surface 411 of the boss 41 until it achieves the top surface 412 of the boss.

Following, the first locking pin 11 rotates toward the direction of the stopper 42 along the top surface 412 until it is propped against the stopper 42 in presence of the resetting force of the spring 6, and the second locking pin 12 is propped against the stop piece 31 which is identical in the original state.

Advantageously, the tent support can be unfolded stably because the tube piece 1, the tube holder 2 and the handle 3 are locked rather than rotates oppositely. Moreover, the tent can be unfolded with one hand by pushing the handle 3 upward only during unfolding the above-mentioned tent.

On the other hand, when the tent is required to fold, rotate the handle 3 reversely to make the first locking pin 11 of the tube piece 11 move toward the direction far away from the stop piece 42 until it is removed out from the top surface of the boss.

More specifically, the first locking pin 11 can move downward directly along the gap between the boss 41 and the other stopper 42 by pulling the handle 3 downward. Advantageously, during this process, the spring 6 is twisted and the second locking pin 12 gradually moves away from the stop piece 31 which is propped against the second locking pin 12 originally.

After achieving the position downward, the first locking pin 11 rotates toward the direction of the guide inclined surface 411 of the boss 41 again in presence of the resetting force of the spring 6 until the first locking pin 11 is propped against the guide inclined surface 411, and the second locking pin 12 is propped against the stop piece 31 which is identical in the original state. Thus, the tent is folded at this moment.

In summary, as illustrated most notably in its FIGS. 1-7, a snap-in and support structure of a tent support is disclosed including a tube piece 1; a tube holder 2; a handle 3 oppositionally extendably circumferentially coupled to the tube holder 2; and a locking sleeve 4 including on an inner circumferential wall a boss 41 having a slidably coupled inclined surface 411 and a top surface 412.

In some embodiments, the slidably coupled inclined surface 411 on a first side of the boss 41 ascends spirally from a bottom to a top of the inner circumferential wall and wherein the tube piece 1 is oppositionally, vertically, rotatably slidable about the tube holder 2 and the handle 3. In some embodiments, a stop piece 31 is arranged about the handle 3 and/or a first locking pin 11 that traversely extends against the slidably coupled inclined surface 411 in an original state, i.e., an unlocked state, and along a circumferential direction. In some embodiments, the first locking pin 11 stopped above the top surface 412 proximal to a second side of the boss 41 a locking state and/or a second locking pin 12 traversely extended against the stop piece 31. In some embodiments, a spring 6 is coupled within a sleeve and along a periphery of the tube piece 1 and one end of the spring 6 coupled to the tube piece 1 and an other end to the tube holder 2.

In some embodiments, a tube holder cavity 21 includes an upper portion formed along a midline of the tube holder 2, at least one portion of the locking sleeve 4 coupled in the tube holder cavity 21 and/or baffle 13 on a portion of the tube piece 1 within the tube holder cavity 21 that are positioned below the locking sleeve 4. In one example, the spring 6 is coupled between the baffle 13 and a bottom wall of the tube holder cavity 21 and fixed within the baffle 13 and a bottom wall of a tube holder cavity 21 respectively.

In step 808, slidably couple an inclined surface 411 of a locking sleeve 4 on a first side of the boss 41.

In step 810, ascends spirally a first locking pin from a bottom to a top surface 412 of an inner circumferential wall on a locking sleeve 4.

In step 812, traversely extend a first locking pin 11 against the slidably coupled inclined surface 411 in an original state and along a circumferential direction. In one additional embodiment, the step 812 further includes stop the first locking pin 11 above the top surface 412 proximal to a second side of the boss 41 in a locking state.

In step 814, traversely extends a second locking pin 12 against a stop piece 31 about the handle 3. In additional embodiment, step 814 further includes slidably couple the tube piece 1 in a tube holder cavity 21 having an upper portion formed along a midline of the tube holder 2, at least one portion of the locking sleeve 4 coupled in the tube holder cavity 21.

In step 816, slidably couple baffle 13 on a portion of the tube piece 1 within the tube holder cavity 21 that is positioned below the locking sleeve 4. In an additional embodiment, step 816 further includes slidably couple the spring 6 between the baffle 13 and a bottom wall of the tube holder cavity 21 and fixed within the baffle 13 and a bottom wall of the tube holder cavity 21 respectively. In an additional embodiment, step 816 further includes extend motion of the spring 6 between an upper lug 61 and a lower lug 62 respectively located on an upper and a lower end of the spring 6.

In step 818, extend upwards of the tube piece 1 between the baffle 13 located proximally between a first positioning hole 131, and a bottom of the tube holder cavity 21 is provided with a second positioning hole 211.

In step 820, extend motion upwards of the spring 6 between the upper lug 61 that couples through the first positioning hole 131, and the lower lug 61 that couples through the second positioning hole 211. In one additional embodiment, step 820 includes twist the upper lug 61 for a specified angular direction in the circumferential direction oppositionally to that of the lower lug 62.

In step 822, extend upwards a stopper 42 beyond the top surface 412. In one additional step of 822, facilitate locking with the stopper 42 on the second side of the inclined surface 411 of the first locking pin 11 in the locking state.

In one additional embodiment of step 822, traversely extends the first locking pin 11 through the tube piece 1 and though an additional boss 41 positioned about the boss 41 along the circumferential direction. In one additional embodiment of step 822, traversely extends the first locking pin 11 through a gap formed by the stopper 42 corresponding to the boss 41 and the additional boss 41.

In yet another additional embodiment of step 822, traversely extends the second locking pin 12 through the tube piece 1 and through the stop piece 31 and arrange an additional stop piece 31 positioned along the circumferential direction. In yet another additional embodiment of step 822, traversely extend a limiting groove 32 formed among the two stop pieces 31; and position the second locking pin 12 in the limiting groove 32 after passing through an end of the tube piece 1.

It should be noted that step(s) 812-822 is/are optional steps and may not be implemented in all cases. Optional steps of method 800 are illustrated using dotted lines in FIG. 8 so as to distinguish them from the other steps of method 800.

It should be noted as herein described in the method, the steps and/or method of contemplated use can be carried out in many different ways, procedures, and the like according to, for example, one or more user preference(s). “[S]tep of” should not be interpreted as “step for”, in the claims herein and is not intended to invoke the provisions of 35 U.S.C. § 112, ¶ 6.

Thus, specific embodiments and applications of system and apparatus for foldable tent and a clamping and supporting structure have been disclosed. It should be apparent, however, to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Insubstantial changes from the claimed subject matter as viewed by a person with ordinary skill in the art, now known or later devised, are expressly contemplated as being equivalent within the scope of the claims.

Therefore, obvious substitutions now or later known to one with ordinary skill in the art are defined to be within the scope of the defined elements. The claims are thus to be understood to include what is specifically illustrated and described above, what is conceptually equivalent, what can be obviously substituted and also what essentially incorporates the essential idea of the disclosure. In addition, where the specification and claims refer to at least one of something selected from the group consisting of A, B, C and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
