Description

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims priority to Chinese Utility Model Application CN 201620282742.2 filed Apr. 7, 2016. The disclosure of the application is incorporated herein for all purposes by reference in its entirety.

FIELD OF THE INVENTION

The present invention generally relates to tent frames and tents, and more particularly, relates to tent frames and tents with slidably coupled top poles.

BACKGROUND

Typical existing tents have a single top pole. To provide a larger space for use, the single top pole is usually long. Such a long single top pole is inconvenient for storage, shipping and transportation. As such, it increases the transportation cost and decreases the profits.

To reduce the sizes of the folded tents while maintaining the capability of providing a relatively larger usable space when unfolded, some existing tents utilize a telescopic top pole. An example of such tents is disclosed in Chinese Patent No. 201420213980.9, entitled “A Tent Frame”, the disclosure of which is incorporated herein for all purposes by reference in its entirety. The tent frame includes a top pole made of an inner pole and an outer pole telescopically coupled to each other. The inner pole is smaller than the outer pole. However, to support the tent cloth and other members of the tent when the tent is unfolded, the inner pole needs to withstand substantially the same amount of force as the outer pole. As such, the inner pole may need to be made of a material different than that of the outer pole, or have a thicker wall than that of the outer pole. In addition, as the inner pole and the outer pole are telescopically coupled to each other, the tent cloth cannot be folded or unfolded along with the tent frame. As such, the tent is not convenient to use.

Given the current state of the art, there remains a need for tent frames and tents that address the abovementioned issues.

The information disclosed in this Background section is provided for an understanding of the general background of the invention and is not an acknowledgement or suggestion that this information forms part of the prior art already known to a person skilled in the art.

DETAILED DESCRIPTION

Reference will now be made in detail to implementations of exemplary embodiments of the present invention as illustrated in the accompanying drawings. The same reference indicators will be used throughout the drawings and the following detailed description to refer to the same or like parts. Those of ordinary skill in the art will understand that the following detailed description is illustrative only and is not intended to be in any way limiting. Other embodiments of the present invention will readily suggest themselves to such skilled persons having benefit of this disclosure.

In the interest of clarity, not all of the routine features of the implementations described herein are shown and described. It will be appreciated that, in the development of any such actual implementation, numerous implementation-specific decisions are made in order to achieve the developer's specific goals, such as compliance with application- and business-related constraints, and that these specific goals will vary from one implementation to another and from one developer to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking of engineering for those of ordinary skill in the art having the benefit of this disclosure.

Many modifications and variations of the exemplary embodiments set forth in this disclosure can be made without departing from the spirit and scope of the embodiments, as will be apparent to those skilled in the art. The specific exemplary embodiments described herein are offered by way of example only, and the disclosure is to be limited only by the terms of the appended claims, along with the full scope of equivalents to which such claims are entitled.

Embodiments of the present invention are described in the context of tents and tent frames. Tents and tent frames of the present invention can be of various sizes and shapes. Generally, a tent frame of the present invention includes first and second top poles, and first and second connectors fixedly coupled to one of the first and second top poles and slidably coupled to the other of the first and second top poles. In various embodiments, a tent frame of the present invention also includes one or more rotatable poles each pivotally coupled to the first or second connector. As such, on one hand, the tent frames and the tents of the present invention when unfolded provide a relatively larger usable space, for example, to accommodate more people (e.g., four, six, eight, ten or more people). On the other hand, the tent frames and the tents of the present invention when folded are compact and require a relatively smaller storage space. Accordingly, they are convenient for shipping and transportation. In addition, the tent cloth can be folded and unfolded along with the tent frame of the present invention. As such, the tents of the present invention are very convenient to use.

Referring now to FIGS. 1-5, there is depicted an exemplary tent in accordance with some exemplary embodiments of the present invention. As show, tent 1 includes a tent frame such as tent frame 100 and a tent cloth such as tent cloth 200 coupled to and supported by the tent frame.

Tent frame 100 includes top poles such as first top pole 11 and second top pole 12. First top pole 11 has a first end portion (e.g., the portion at or adjacent to reference numeral 13 in FIG. 4) and a second end portion (e.g., the portion at or adjacent to reference numeral 50 on the left side of FIG. 4). Similarly, second top pole 12 has a first end portion (e.g., the portion at or adjacent to reference numeral 14 in FIG. 4) and a second end portion (e.g., the portion at or adjacent to reference numeral 50 on the right side of FIG. 4).

Tent frame 100 also includes connectors such as first connector 13 and second connector 14. First connector 13 is fixedly coupled to the first end portion of the first top pole, and slidably coupled to and movable along the second pole. Second connector 14 is fixedly coupled to the first end portion of the second top pole, and slidably coupled to and movable along the first top pole.

Tent frame 100 further includes a locking mechanism such as locking mechanism 20 to selectively restrict the first and second top poles from moving with respect to each other. Referring to FIGS. 6 and 7, in some exemplary embodiments, locking mechanism 20 includes a U-shaped elastic member such as U-shaped elastic member 21 and a protrusion such as protrusion 22 disposed at or integrally formed with the U-shaped elastic member. In an exemplary embodiment, the protrusion is disposed or integrally formed at an end portion of the U-shaped elastic member. In an exemplary embodiment, the protrusion is a boss or the like.

To accommodate the U-shaped elastic member, the second top pole or at least the first end portion of the second top pole is hollow, with a hole formed on a side wall at or adjacent to the first end portion of the second top pole. The U-shaped elastic member is disposed inside of the first end portion of the second top pole, and pushes the protrusion outwardly such that the protrusion protrudes outside of the second top pole through the hole formed at the first end portion of the second top pole.

Locking mechanism 20 also includes a knob formed with a push button such as push button 23 and a receptacle such as receptacle 24. In an exemplary embodiment, the knob is disposed at or formed integrally with first connector 13. In an exemplary embodiment, the knob is fixedly disposed at the first end portion of the first top pole. The receptacle is configured to receive the protrusion and thus restricts the first and second top poles from moving with respect to each other, thereby assisting in stabilizing the tent when unfolded. The push button is configured to push the protrusion and thus release the protrusion from the receptacle of the knob or from both the receptacle of the knob and the hole formed at the first end portion of the second top pole. As a result, the first and second top poles are allowed to move with respect to each other, thereby allowing the tent and the tent frame to fold or unfold.

In some exemplary embodiments, tent frame 100 includes one or more rotational poles to assist in supporting, extending and/or stretching the tent cloth. For instance, in an exemplary embodiment, tent frame 100 includes first rotatable pole 40 with its first end portion pivotally connected to first connector 13 such that the first rotatable pole can be rotated between a first position and a second position. In an exemplary embodiment, first rotational pole 40 is rotatable towards the second connector between a first position that is substantially perpendicular to the second top pole (e.g., the position shown in FIG. 1) and a second position that is substantially parallel to the second top pole (e.g., the position shown in FIG. 5). In some exemplary embodiments, the second end portion of the first rotatable pole includes a fastener such as first fastener 70 (e.g., fastener 70 at the front side of the tent in FIG. 4) to couple with the tent cloth. The first fastener can be a buckle, a strip of fabric, or the like. Accordingly, the tent cloth can be unfolded or unfolded along with the tent frame.

In some exemplary embodiments, tent frame 100 includes second rotatable pole 30. Similar to first rotatable pole 40, second rotatable pole 30 has its first end portion pivotally connected to the second connector such that the second rotatable can be rotated between a third position and a fourth position. In an exemplary embodiment, the second rotatable pole is rotatable towards the first connector between a third position that is substantially perpendicular to the first top pole and a fourth position that is substantially parallel to the first top pole. In an exemplary embodiment, the second rotatable pole includes a second fastener such as second fastener 70 (e.g., fastener 70 at the back side of the tent in FIG. 4) at its second end portion to couple with the tent cloth.

In some exemplary embodiments, tent frame 100 also includes a plurality of supporting poles such as supporting poles 60 pivotally connected to the second end portions of the first and second top poles. The plurality of supporting poles supports the first and second top poles when the tent frame is unfolded. For instance, in some exemplary embodiments, tent frame 100 includes a third connector such as third connector 50 (e.g., the connector on the left side of FIG. 4) to pivotally connect a first plurality of supporting poles with the second end portion of first top pole 11. The first plurality of supporting poles can include two, three, or more supporting poles. Tent frame 100 also includes a fourth connector such as fourth connector 50 (e.g., the connector on the right side of FIG. 4) to pivotally connect a second plurality of supporting poles with the second end portion of the second top pole. The second plurality of supporting poles can include the same number of supporting poles as the first plurality of supporting poles or different number of supporting poles.

In some exemplary embodiments such as those illustrated in FIGS. 1-5, supporting pole 60 in the first or second plurality of supporting poles includes an upper supporting pole such as upper supporting pole 61 and a lower supporting pole such as lower supporting pole 62. The upper supporting pole has first and second end portions, with the first end portion pivotally connected to the third or fourth connector, and the second end portion pivotally connected to a first end portion of the lower supporting pole. The second end portion of the lower supporting pole is configured to be disposed at a ground. In an exemplary embodiment, lower supporting pole 62 is telescopic, or has a length that is adjustable.

Referring to FIGS. 8-12, in an exemplary alternative embodiment, supporting pole 60 includes lower supporting pole 62 but not upper supporting pole 61. In such an exemplary embodiment, the first end portion of the lower supporting pole 62 is pivotally connected to the first or second top poles through the third or fourth connector.

Referring to FIGS. 1-5 and 8-12, the tents and the tent frames of the present invention are easy to fold and unfold. For instance, FIG. 1 illustrates a tent of the present invention in an unfolded state. To fold the tent, retract the lower supporting poles and rotate upwardly the retracted lower supporting poles toward the corresponding upper poles. Retract the first and second top poles. While the first and second top poles are retracting, the rotatable poles rotate towards the first and second top poles and are eventually placed side by side with the first and second top poles. Rotation of the rotatable poles in turn folds the tent cloth. It should be noted that retracting of the first and second top poles can be performed prior to or subsequent to retracting of the lower supporting poles. Afterwards, rotate the upper supporting pole along with the lower supporting pole towards the top poles to complete the folding process. Similarly, FIG. 8 illustrates an alternative tent of the present invention in an unfolded state. To fold the alternative tent, retract the lower supporting poles and retract the first and second top poles. Then, rotate the retracted lower supporting poles towards the top poles as illustrated in FIG. 13 to complete the folding process. The folded tent frame is illustrated in FIG. 14. Reversing the processes will unfold the tent frames and the tents.

As disclosed herein, the tent frames and the tents of the present invention have several advantages. For instance, the tent frames and the tents of the present invention when unfolded provide a relatively larger usable space and thus can accommodate more people. The tent frames and the tents of the present invention when folded are compact and require a relative smaller storage space, and are thus convenient for shipping and transportation. Also, the tent frames and the tents of the present invention are easy to fold and unfold. In addition, the tent cloth can be folded together with the tent frame. As such, there is no need to fold the tent frame and the tent cloth separately, making the tents of the present invention very convenient to use.
