COLLAPSIBLE JOINT TO SUPPORT A TENT AND ASSOCIATED METHODS
A first elongate member and a second elongate member of a collapsible joint may each be pivotally engaged with at least one connecting member. A first locking pin may be positioned within aligned openings in the first elongate member and the at least one connecting member in a first engaged position. A second locking pin may be positioned within openings in the second elongate member and the at least one connecting member in a second engaged position. When the first locking pin is in the first engaged position and the second locking pin is in the second engaged position, the first elongate member may be substantially coaxial with the second elongate member.
The present invention relates generally to collapsible joints. More specifically, the present invention relates to collapsible joints that may be utilized with tents to facilitate the assembly and disassembly process and simplify storage of tent components.
BACKGROUNDTraditional spring bar assemblies for spring bar tents typically have two separate poles which can be connected together to apply an opposing tension or stretching force between opposite ends of the roof material of the spring bar tent. In this manner, downward force placed on the poles translates into an outwardly directed stretching/expanding force on the tent fabric. This tension or stretching force between the two separate poles pushes outward on both ends of the roof material of the spring bar tent to give increased headroom to users so they can more easily stand up and move around within the spring bar tent.
However, connecting these two separate poles together may be difficult. For example, a user may be required to align both poles together, push downward on both poles simultaneously to counter the spring force while maintaining alignment of the two poles, and then lock the two poles in place with a suitable locking mechanism, such as a hollow sleeve. This assembly process may require a second user to assist the first user, as the first user may need both hands to hold the two separate poles in place while the second user slides the hollow sleeve over the connection point between the two separate poles. Accordingly, an improved spring bar design to facilitate the assembly process and improve safety may be desirable.

The second locking pin may be configured to substantially prevent the connecting bar from pivoting with respect to the second elongate member when the second locking pin is engaged within the second connecting bar opening and the second elongate member opening in a second engaged position. Additionally, when the first locking pin is in the first engaged position and the second locking pin is simultaneously in the second engaged position, the first elongate member and the second elongate member may be substantially coaxially aligned with each other and the first elongate member and the second elongate member may be substantially prevented from pivoting with respect to each other.
A method of assembling a collapsible joint is disclosed. The collapsible joint is provided in an unengaged configuration. The first connecting bar opening, the third connecting bar opening, and the first elongate member opening may be aligned with each other. Thereafter, the first locking pin may be positioned in the first engaged position within the first connecting bar opening, the third connecting bar opening, and the first elongate member opening.

Thereafter, the second locking pin may be positioned in the second engaged position within the second connecting bar opening, the fourth connecting bar opening, and the second elongate member opening such that the first elongate member and the second elongate member are substantially coaxially aligned with each other. In various embodiments, an alignment force may be applied to a cross bar connecting the first connecting bar and the second connecting bar to align the second connecting bar opening, the fourth connecting bar opening, and the second elongate member opening. In some embodiments, positioning the first elongate member and the second elongate member such that the first elongate member and the second elongate member are substantially coaxially aligned with each other may occur before positioning the first locking pin in the first engaged position or before positioning the second locking pin in the second engaged position.

In the figures, certain components may appear many times within a particular drawing. However, only certain instances of the component may be identified in the figures to avoid unnecessary repetition of reference numbers and lead lines.

Traditional spring bar assemblies (not shown) typically comprise two separate poles which may be connected together to apply an opposing tension/stretching force between opposite ends of the roof material of the tent body. This tension/stretching force between the two separate poles may act to push outward on both ends of the roof material of the tent body and give the spring bar tent its unique shape and larger roof area. The unique shape and larger roof area of the spring bar tent generally provide a user (not shown) with more headroom to stand up and move around within the spring bar tent.
Connecting the two separate poles of traditional spring bar assemblies to create an opposing tension/stretching force may be a difficult and even a hazardous task. For example, the user may be required to align both poles together and then push down on both poles simultaneously to create the tension/stretching force on the roof material of the tent, while also trying to maintain alignment of the two separate poles so that the poles do not slip out of alignment, potentially striking the user and causing injury. Once the two poles are aligned under tension, the user may then use a suitable locking mechanism, such as a hollow sleeve (not shown), to keep the two separate poles locked in place in this aligned configuration. This assembly process may require a second user to assist the first user, as the first user may need both hands to hold the two separate poles in place while the second user slides the hollow sleeve over the connection point between the poles. Accordingly, a collapsible joint 170 according to the present disclosure may be included in the spring bar tent 100 design to facilitate the assembly process and improve safety.

In this manner, when the first locking pin 250 is in the first engaged position and the second locking pin 260 is simultaneously in the second engaged position, the first elongate member 210 and the second elongate member 220 may be substantially coaxially aligned with each other and the first and second elongate members 210, 220 may be substantially prevented from pivoting with respect to each other.
