Abstract

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.

Description

TECHNICAL FIELD

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.

BACKGROUND

Traditional 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.

SUMMARY

Embodiments of the disclosed subject matter are provided below for illustrative purposes and are in no way limiting of the claimed subject matter.
In various embodiments, a collapsible joint configured to support a tent may include a first elongate member, a second elongate member, a first connecting bar, a second connecting bar, a first locking pin, a second locking pin, a first pintle, and a second pintle. The first elongate member may have a first elongate member longitudinal axis, a first elongate member opening, and a first elongate member pivot axis. The first elongate member opening may be spaced apart from the first elongate member pivot axis along the first elongate member longitudinal axis. The second elongate member may have a second elongate member longitudinal axis, a second elongate member opening, and a second elongate member pivot axis. The second elongate member opening may be spaced apart from the second elongate member pivot axis along the second elongate member longitudinal axis. The first connecting bar may have a first connecting bar longitudinal axis. The first connecting bar may further comprise a first connecting bar pivot point, a second connecting bar pivot point, a first connecting bar opening, and a second connecting bar opening offset from each other along the first connecting bar longitudinal axis. The first connecting bar may be configured to pivotally couple the first elongate member to the second elongate member with a first pintle substantially coaxially aligned with the first elongate member pivot axis, the first pintle pivotally coupling the first elongate member to the first connecting bar at the first connecting bar pivot point, and a second pintle substantially coaxially aligned with the second elongate member pivot axis, the second pintle pivotally coupling the second elongate member to the first connecting bar at the second connecting bar pivot point. The second connecting bar may be parallel to the first connecting bar and have a second connecting bar longitudinal axis, a third connecting bar pivot point, a fourth connecting bar pivot point, a third connecting bar opening, and a fourth connecting bar opening offset from each other along the second connecting bar longitudinal axis. The second connecting bar may be configured to pivotally couple the first elongate member to the second elongate member with a first pintle substantially coaxially aligned with the first elongate member pivot axis, the first pintle pivotally coupling the first elongate member to the second connecting bar at the third connecting bar pivot point and the second pintle substantially coaxially aligned with the second elongate member pivot axis, the second pintle pivotally coupling the second elongate member to the second connecting bar at the fourth connecting bar pivot point. The first locking pin may be configured to substantially prevent the first connecting bar and the second connecting bar from pivoting with respect to the first elongate member when the first locking pin is engaged within the first connecting bar opening, the third connecting bar opening, and the first elongate member opening in a first engaged position. The second locking pin may be configured to substantially prevent the first connecting bar and the second connecting bar from pivoting with respect to the second elongate member when the second locking pin is engaged within the second connecting bar opening, the fourth 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, the first elongate member and the second elongate member may be substantially prevented from pivoting with respect to each other, and the first locking pin and the second locking pin may be intermediate the first pintle and the second pintle along an engaged position longitudinal axis.
In other embodiments, a collapsible joint configured to support a tent may include a first elongate member, a second elongate member, a connecting bar, a first locking pin, a second locking pin, a first pintle, and a second pintle. The first elongate member may have a first elongate member longitudinal axis, a first elongate member opening, and a first elongate member pivot axis. The first elongate member opening may be spaced apart from the first elongate member pivot axis along the first elongate member longitudinal axis. The second elongate member may have a second elongate member longitudinal axis, a second elongate member opening, and a second elongate member pivot axis. The second elongate member opening may be spaced apart from the second elongate member pivot axis along the second elongate member longitudinal axis. The connecting bar may have a connecting bar longitudinal axis, a first connecting bar pivot point, a second connecting bar pivot point, a first connecting bar opening, and a second connecting bar opening offset from each other along the connecting bar longitudinal axis. The connecting bar may be configured to pivotally couple the first elongate member to the second elongate member with a first pintle substantially coaxially aligned with the first elongate member pivot axis, the first pintle pivotally coupling the first elongate member to the connecting bar at the first connecting bar pivot point, and a second pintle substantially coaxially aligned with the second elongate member pivot axis, the second pintle pivotally coupling the second elongate member to the connecting bar at the second connecting bar pivot point. The first locking pin may be configured to substantially prevent the connecting bar from pivoting with respect to the first elongate member when the first locking pin is engaged within the first connecting bar opening and the first elongate member opening in a first engaged position. 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. The second connecting bar opening, the fourth connecting bar opening, and the second elongate member opening may be aligned with each other. 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.

FIG. 1 illustrates one embodiment of a spring bar tent 100 that may be used with any of the collapsible joint embodiments of the present disclosure. FIG. 2 is an exploded view of the spring bar tent 100 shown in FIG. 1. The illustrated spring bar tent 100 may generally include components such as a ground tarp 110, a tent body 120, adjustable poles 131, 132, resilient poles 141, 142, 143, 144, connector end pieces 151, 152, and a spring bar assembly 160, as well as any other suitable component that may be used in conjunction with a spring bar tent 100.
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.
FIGS. 3-8B illustrate various views of a collapsible joint 200, according to one embodiment of the present disclosure, which may be used with the spring bar tent 100 shown in FIGS. 1 and 2. Specifically, FIG. 3 is a top side view of the illustrated embodiment of the collapsible joint 200 with a user's hand applying a downward force to the collapsible joint 200 in order to align the collapsible joint 200; FIG. 4 is a left side elevational view of the collapsible joint 200 of FIG. 3 in a non-aligned configuration; FIG. 5A is a left perspective view of the collapsible joint 200 of FIG. 3 in a non-aligned configuration, while FIG. 5B is a left side elevational view of the collapsible joint 200 in the same non-aligned configuration of FIG. 5A; FIG. 6A is a left perspective view of the collapsible joint 200 of FIG. 3 in a non-aligned configuration with the first locking pin 250 (labeled with reference numerals and shown only in FIGS. 3 and 6A-8B) engaged, while FIG. 6B is a left side elevational view of the collapsible joint 200 in the same non-aligned configuration of FIG. 6B; FIG. 7A is a left perspective view of the collapsible joint 200 of FIG. 3 in an aligned configuration with a user's hand applying an alignment force to the collapsible joint 200 in preparation for inserting the second locking pin 260 (labeled with reference numerals and shown only in FIGS. 3, 7A and 8A-B), while FIG. 7B is a left side elevational view of the collapsible joint 200 of FIG. 3 in the same aligned configuration shown in FIG. 7A; FIG. 8A is a left perspective view of the collapsible joint 200 of FIG. 3 in an aligned configuration with the first and second locking pins 250, 260 engaged, while FIG. 8B is a left side elevational view of the collapsible joint 200 in the same aligned configuration as FIG. 8A with the first and second locking pins 250, 260 engaged.
The collapsible joint 200 may generally include a first elongate member 210, a second elongate member 220, a first connecting bar 230, a second connecting bar 240 (labeled with reference numerals and shown only in FIGS. 3, 5A, 6A, 7A and 8A), a first locking pin 250, a second locking pin 260, a first pintle 270, and a second pintle 280 (labeled with reference numerals and shown only in FIGS. 3-4, 5A-6B, and 7B-8B).
The first elongate member 210 may have a first elongate member longitudinal axis 210 a (illustrated only in FIG. 5A), a first elongate member pivot axis 210 b (illustrated only in FIG. 5A), and a first elongate member opening 210 c (labeled with reference numerals and shown only in FIGS. 3, 4 and 5B and labeled with a reference numeral having a lead line comprising an arrowhead, although not visible, in FIG. 5A). The first elongate member opening 210 c may be spaced apart from the first elongate member pivot axis 210 b along the first elongate member longitudinal axis 210 a. Likewise, the second elongate member 220 may have a second elongate member longitudinal axis 220 a (illustrated only in FIG. 5A), a second elongate member pivot axis 220 b (illustrated only in FIG. 5A), and a second elongate member opening 220 c (labeled with reference numerals and shown only in FIGS. 3, 4 and 5A-B). The second elongate member opening 220 c may also be spaced apart from the second elongate member pivot axis 220 b along the second elongate member longitudinal axis 220 a. It will be understood that any and all of the elongate members described herein may employ tubing having, for example, an outer perimeter in a square, circular, elliptical or rectangular cross-sectional shape.
The first connecting bar 230 may have a first connecting bar longitudinal axis 230 a (illustrated only in FIG. 5A), a first connecting bar pivot point 230 b (labeled generally with a reference numeral having a lead line comprising an arrowhead only in FIGS. 3-5A), a second connecting bar pivot point 230 c (labeled generally with a reference numeral having a lead line comprising an arrowhead only in FIGS. 3-5A), a first connecting bar opening 230 d (labeled with reference numerals only in FIGS. 3-5B), and a second connecting bar opening 230 e (labeled with reference numerals only in FIGS. 3-6B and 7B). The first connecting bar pivot point 230 b, the second connecting bar pivot point 230 c, the first connecting bar opening 230 d, and the second connecting bar opening 230 e may be offset from each other along the first connecting bar longitudinal axis 230 a. The first connecting bar 230 may be configured to pivotally couple the first elongate member 210 to the second elongate member 220 with the first pintle 270 being substantially coaxially aligned with the first elongate member pivot axis 210 b and the first pintle 270 pivotally coupling the first elongate member 210 to the first connecting bar 230 at the first connecting bar pivot point 230 b, as well as the second pintle 280 being substantially coaxially aligned with the second elongate member pivot axis 220 b with the second pintle 280 pivotally coupling the second elongate member 220 to the first connecting bar 230 at the second connecting bar pivot point 230 c.
Similarly, the second connecting bar 240 may be substantially parallel to the first connecting bar 230. The second connecting bar 240 may, in various embodiments, be a mirror image of the first connecting bar 230, as indicated in FIG. 3. Accordingly, the second connecting bar 240 may have a second connecting bar longitudinal axis 240 a (illustrated only in FIG. 5A), a third connecting bar pivot point 240 b (labeled generally with a reference numeral having a lead line comprising an arrowhead only in FIGS. 3 and 5A, and comprising a mirror image of the first connecting bar pivot point 230 b), a fourth connecting bar pivot point 240 c (labeled generally with a reference numeral having a lead line comprising an arrowhead only in FIGS. 3 and 5A, and comprising a mirror image of the second connecting bar pivot point 230 c), a third connecting bar opening 240 d (labeled with a reference numeral and shown only in FIG. 3 and labeled generally with a reference numeral having a lead line comprising an arrowhead, although not visible, only in FIG. 5A), and a fourth connecting bar opening 240 e (labeled with a reference numeral and shown only in FIG. 3 and labeled generally with a reference numeral having a lead line comprising an arrowhead, although not visible, only in FIG. 5A). The third connecting bar pivot point 240 b, the fourth connecting bar pivot point 240 c, the third connecting bar opening 240 d, and the fourth connecting bar opening 240 e may be offset from each other along the second connecting bar longitudinal axis 240 a. The second connecting bar 240 may be configured to pivotally couple the first elongate member 210 to the second elongate member 220 with the first pintle 270 being substantially coaxially aligned with the first elongate member pivot axis 210 b and the first pintle 270 pivotally coupling the first elongate member 210 to the second connecting bar 240 at the third connecting bar pivot point 240 b, as well as the second pintle 280 being substantially coaxially aligned with the second elongate member pivot axis 220 b with the second pintle 280 pivotally coupling the second elongate member 220 to the second connecting bar 240 at the fourth connecting bar pivot point 240 c.
A first locking pin 250 may be configured to substantially prevent the first connecting bar 230 and the second connecting bar 240 from pivoting with respect to the first elongate member 210 when the first locking pin 250 is engaged within the first connecting bar opening 230 d, the third connecting bar opening 240 d, and the first elongate member opening 210 c in a first engaged position. Likewise, a second locking pin 260 may be configured to substantially prevent the first connecting bar 230 and the second connecting bar 240 from pivoting with respect to the second elongate member 220 when the second locking pin 260 is engaged within the second connecting bar opening 230 e, the fourth connecting bar opening 240 e and the second elongate member opening 220 c in a second engaged position. 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.
In the collapsible joint 200 embodiment shown in FIGS. 3-8B, the first locking pin 250 and the second locking pin 260 may be disposed intermediate the first pintle 270 and the second pintle 280 along engaged position longitudinal axis 296 (illustrated only in FIG. 8A). However, other collapsible joint embodiments may include alternative arrangements and placements for locking pins and pintles, as will be described in more detail below.
In the collapsible joint 200 embodiment shown in FIGS. 3-8B, a first resilient safety retainer 251 (labeled with reference numerals and shown only in FIGS. 3 and 6A-8B) may be coupled to the first locking pin 250 and configured to resist removal of the first locking pin 250 from the first connecting bar opening 230 d, the third connecting bar opening 240 d, and the first elongate member opening 210 c. Likewise, a second resilient safety retainer 261 (labeled with reference numerals and shown only in FIGS. 3, 7A-8B) may be coupled to the second locking pin 260 and configured to resist removal of the second locking pin 260 from the second connecting bar opening 230 e, the fourth connecting bar opening 240 e, and the second elongate member opening 220 c. Each of the first resilient safety retainer 251 and second resilient safety retainer 261 may comprise a pivoting end 261 a, looped end 261 b, a resilient, intermediate arcuate member 261 c disposed between the pivoting end 261 a and the looped end 261 b, as illustrated in FIG. 7A. At the pivoting end 261 a, each resilient safety retainer 251, 261 is pivotally coupled to the first end the associated locking pin 250, 260, while the looped end 261 b may be selectively disposed around and engage the opposite end of the coupled locking pin 250, 260.
Referring once again generally to FIGS. 3-9A, the collapsible joint 200 (as well as all other collapsible joints 170, 300, 400, 500, 600, 700, 800, 1100 described herein) may overcome the difficulty and safety concerns of traditional spring bar assemblies previously described by pivotally coupling the first elongate member 210 and the second elongate member 220 to each other via the first connecting bar 230 and the second connecting bar 240. This configuration allows a single user to apply an alignment force to the collapsible joint 200 with one hand, as can be seen in FIGS. 3 and 7A. The user may then insert the locking pins 250, 260 with the user's other free hand to lock the collapsible joint 200 in an aligned/engaged position as can be seen in FIGS. 8A and 8B.
