This application will be described in detail below with reference to the following embodiments.

Embodiment 1

Referring to an embodiment shown in FIGS. 1-4, a dual-purpose stand for hammock and hammock chair is provided, including one support assembly. The support assembly comprises a bottom rod 1. Two ends of the bottom rod 1 are each provided with a suspension frame 2. A bending portion (S) is provided at a lower part of the suspension frame 2. The suspension frame 2 adopts a two-section connection structure. The bottom rod 1 includes a base rod 11. Two ends of the base rod 11 are each provided with a connecting part 12. A base 13 is provided on the connecting part 12. The connecting part 12 is in extendable-retractable fit with the base rod 11.

Two pin holes are provided on the suspension frame 2 at one end close to the bottom rod 1, and the two pin holes are arranged on the same cross-section. The included angle between the two pin holes is 180°. The component (i.e., the lower part of the suspension frame 2) where the bending portion (S) is located is configured to be adjusted by switching the installation mode to change an extension direction of the upper part of the suspension frame 2, so as to change an inclination angle of the suspension frame 2 after being installed, thereby changing the spacing between the suspension points between the suspension frames.

The suspension frame 2 adopts a two-section assembly structure, shortening a length of a single component and reducing the packaging and transportation cost. The base 13 is in detachable fit with the connecting part 12. The base 13 is made of a hollow square tube. Two ends of the base 13 are each provided with a protective cover, which can not only prevent sundries from entering the base 13, but also prevent the user from being scratched by the end edges of the base 13, making it safer in use. The connecting part 12 is fixedly provided with a mounting seat 13a, having a square structure with one edge open. The opening of the mounting seat 13a faces down. When installing, the base 13 is inserted into the mounting seat 13a, and locked with a locking member 13b, facilitating the assembly and disassembly. Considering that the base 13 has a square cross-section, the placement is more stable.

The connecting part 12 is in extendable-retractable fit with the base rod 11. The connecting part 12 is provided with a extendable-retractable insertion pin. Two ends of the base rod 11 are respectively symmetrically provided with a pin hole, and a middle portion of the base rod 11 is symmetrically provided with two pin holes. The insertion pin is configured to be in fit with different pin holes to adjust an insertion depth of the connecting parts 12 to adjust a length of the bottom rod 1, so as to adjust the spacing between suspension points of suspension frames.

In this embodiment, the bending portion (S) has an obtuse-angle structure. As shown in FIG. 1, when the hammock is suspended, the cooperation between the connecting parts 12 at both ends and the base rod 11 is in an elongated state. The suspension frame 2 is extended outward using the obtuse-angle structure (A center line of a connecting portion where a lower end of the suspension frame 2 is connected to the connecting part 12 is taken as a reference.). At this time, an included angle between the suspension frames 2 on both sides is relatively large, that is, a spacing between the suspension points of the suspension frames 2 on both sides is relatively large, which is suitable for suspending a hammock. As shown in FIG. 3, when the hammock chair is suspended, the cooperation between the connecting parts 12 at both ends and the base rod 11 is in a shortened state. The suspension frame 2 is retracted inward using an obtuse-angle structure (A center line of a connecting portion where a lower end of the suspension frame 2 is connected to the connecting part 12 is taken as a reference.) At this time, an included angle between the suspension frames 2 on both sides is relatively small, that is, the spacing between the suspension points of the suspension frames 2 on both sides is relatively small, which is suitable for suspending a hammock chair. By comparing the two suspension forms shown in FIGS. 1 and 3, it can be found that the included angle between the two suspension frames 2 can be in one support assembly, adjusted by switching the installation mode (the azimuth difference between the two installation modes is 180°) of the component where the bending portion (S) is located, so as to conveniently adjust the spacing between suspension points of suspension frames to meet the suspension requirements of the hammock and the hammock chair by one support assembly.

Embodiment 2

Referring to FIGS. 5-7, a dual-purpose stand provided in Embodiment 2 is basically the same as the dual-purpose stand provided in Embodiment 1, except for the structure of the base 13. In this embodiment, the base 13 includes a connecting rod 13c and a first support rod 13d. Each connecting part 12 is fixedly provided with a connecting rod 13c. Two ends of the connecting rod 13c are each connected to a first support rod 13d, where the first support rod 13d is detachable. The first support rod 13d is connected to the connecting rod 13c to form a stable support structure.

In this embodiment, the connecting part 12 is in extendable-retractable fit with the base rod 11. The insertion pin is provided on the base rod 11, and the pin hole is provided on the connecting part 12. When connected, the connecting part 12 is sleevedly provided outside the base rod 11. The bending portion (S) has an obtuse-angle structure.

As shown in FIG. 5, when the hammock is suspended, the cooperation between the connecting parts 12 at both ends and the base rod 11 is in an elongated state. The suspension frame 2 is extended outward using the obtuse-angle structure (A center line of a connecting portion where a lower end of the suspension frame 2 is connected to the connecting part 12 is taken as a reference.) At this time, the included angle between the suspension frames 2 on both sides is large, that is, the spacing between the suspension points of the suspension frames 2 on both sides is large, which is suitable for suspending a hammock. As shown in FIG. 7, when the hammock chair is suspended, the cooperation between the connecting parts 12 at both ends and the base rod 11 is in a shortened state, and the suspension frame 2 is retracted inward using the obtuse-angle structure (A center line of a connecting portion where a lower end of the suspension frame 2 is connected to the connecting part 12 is taken as a reference.) At this time, the included angle between the suspension frames 2 on both sides is relatively small, that is, the spacing between the suspension points of the suspension frames 2 on both sides is relatively small, which is suitable for suspending the hammock chair.

Embodiment 3

Referring to FIGS. 8-10, a dual-purpose stand provided in Embodiment 3 includes one support assembly, and the dual-purpose stand structure provided in Embodiment 3 is basically the same as that in Embodiment 1, except that the bottom rod 1 includes a base rod 11, an extension rod 14 and two connecting parts 12. The base rod 11 is in detachable fit with the extension rod 14. The two connecting parts 12 are connected to the base rod 11 or the extension rod 14. The two connecting parts 12 are each provided with a base 13.

In this embodiment, the spacing between suspension points of suspension frames is adjusted by whether the extension rod 14 is connected or not. As shown in FIG. 8, when the hammock is suspended, the extension rod 14 is connected to one end of the base rod 11 to further increase the spacing between suspension points of suspension frames. One of the two connecting parts 12 is connected to the base rod 11, the other of the two connecting parts 12 is connected to the extension rod 14. As shown in FIG. 10, when the hammock chair is suspended, the extension rod 14 is disassembled, and two ends of the base rod 11 are each connected to one of the two connecting parts 12. The transformation between the hammock suspension form and the hammock chair suspension form is the same as that in Embodiment 1, which is easy to be realized by switching the installation mode of the component where the bending portion (S) is located.

Embodiment 4

Referring to FIGS. 11 and 12, a dual-purpose stand provided in Embodiment 4 includes two support assemblies. The two support assemblies are configured to support each other to form a stable structure. The bending portion (S) is provided at a lower part of the suspension frame 2. The bottom rod 1 includes a base rod 11. Two ends of the base rod 11 are each connected to a connecting part 12. The connecting part 12 is in extendable-retractable fit with the base rod 11. The lower part of the suspension frame 2 is connected to the connecting part 12. Upper parts of suspension frames 2 are connected to each other at the same side to form an A-shaped structure.

The lower part of the suspension frame 2 is connected to the connecting part 12, and the upper parts of suspension frames 2 are connected to each other at the same side. The bottom rods 1 are arranged in parallel. Each part is connected to form an end-to-end circular structure, so as to form the stable structure to allow the stand to be placed stably. The transformation of the hammock suspension form and the hammock chair suspension form of the stand is easily realized through switching the installation mode of the suspension frame 2.

Embodiment 5

Referring to FIGS. 13-16, a dual-purpose stand provided in Embodiment 5 is basically the same as the dual-purpose stand provided in Embodiment 4, except that the bottom rod 1 includes a base rod 11. Two ends of the base rod 11 are each connected to a connecting part 12. The bending portion (S) is provided on the connecting part 12. The connecting part 12 is in extendable-retractable fit with the base rod 11. The lower part of the suspension frame 2 is connected to the connecting part 12, and upper parts of suspension frames 2 are connected to each other at the same side. In this embodiment, the bending portion (S) is provided on the bottom rod 1.

The transformation of the hammock suspension form and the hammock chair suspension form of the chair can be easily realized by switching the installation mode of the component (i.e., the connecting part 12) where the bending portion (S) is located. As shown in FIG. 14, in the hammock suspension form, an outer portion of the connecting part 12 is inclined downward. As shown in FIG. 16, in the hammock chair suspension form, the outer portion of the connecting part 12 is inclined upward.
