The present application relates to the technical field of hammocks, and in particular to a hammock frame and a hammock having the same.
A hammock generally can be folded, and is often used in outdoor tourism, courtyard leisure, outdoor camping and other occasions. Therefore, it is increasingly popular among users.
The existing hammock is bulky after being folded and is also heavy, so that the packaging cost and transportation cost of products are high, and the existing hammock is not convenient to carry outdoors, adversely affecting the user experience.
Therefore, how to provide a hammock which is small in volume after folding and convenient to carry is a technical problem that the person skilled in this art needs to think about.
An object according to the present application is to provide a hammock frame and a hammock having the same, and the hammock is small in volume after folding and convenient to carry.
To achieve the above object, a hammock frame is provided according to the present application, which includes two sets of connecting rod assemblies located on opposite lateral sides of the frame. Each of the connecting rod assemblies is connected to each other to define the hammock frame. Each connecting rod assembly includes a first rod, a second rod, a third rod, a fourth rod, a fifth rod and a sixth rod, where:
Compared with the above background technology, the hammock frame shown in the embodiments of the present application includes two connecting rod assemblies on lateral sides of the hammock frame where in each connecting rod assembly, the top of the first rod is rotatably connected with the top of the second rod, the bottom of the third rod is rotatably connected with the bottom of the fourth rod, and the first rod is rotatably connected with the third rod, so that the first rod, the second rod, the third rod and the fourth rod are connected to present a double cross rod structure. Moreover, the bottom of the first rod is rotatably connected with the bottom of the fifth rod, and the bottom of the second rod is rotatably connected with the bottom of the sixth rod. Accordingly, in the expanded configuration of the hammock frame, the first rod, the second rod, the fifth rod and the sixth rod are connected to present a “W” shape, and the third rod and the fourth rod are connected to present a “V” shape. In this way, the volume of the hammock frame can be greatly reduced during folding, thus ensuring convenient handling. Meanwhile, compared to sliding structures existing in conventional technology (such as the case where the third rod slides on the fifth rod, and the third rod and the fifth rod need to be unlocked and locked), the hammock frame provided by the embodiments of the present application can be folded and unfolded by rotation, which is easy to operate, and there is no need to unlock the position of the third rod and the fifth rod when sliding.
In an embodiment, a traverse brace member is detachably provided between the tops of the two fifth rods and/or the tops of the two sixth rods.
In an embodiment, each fifth rod and each sixth rod extend outward from bottom to top.
In an embodiment, each connecting rod assembly further includes a sun shade with an adjusting member and a supporting member arranged at the top of the fifth rod. The bottom of the adjusting member and/or the supporting member is rotatably connected to the fifth rod. The height of the adjusting member can be adjusted, so as to adjust the shading angle. The top of the adjusting member and the top of the supporting member are rotatably connected with a ceiling member, and a sleeve member is slidably connected in the ceiling member. The ceiling member and the sleeve member extend toward the sixth rod when the sun shade is deployed with the hammock frame in the expanded position so that the shading area can be adjusted by sliding the sleeve member relative to the ceiling member. In an embodiment, a supporting bar is arranged between the two sleeve members when the sun shade is deployed with the hammock frame in the expanded position. The sunshade can be folded, which is convenient to carry and store.
In an embodiment, a front cross member assembly and a rear cross member assembly are arranged between the two groups of connecting rod assemblies. Each cross member assembly includes a first cross member and a second cross member that are rotatably connected. The bottoms of the first cross member and the second cross member of the front cross member assembly are respectively operatively rotatably connected adjacent to the bottoms of the first rod and the fifth rod and may be connected to an adjacent a foot pad. The tops of the first cross member and second cross member of the front cross member assembly are respectively operatively rotatably connected to joints of the third rod. The bottoms of the first cross member and the second cross member in the rear cross member assembly are respectively operatively rotatably connected adjacent to the bottoms of the second rod and the sixth rod, and may be connected to an adjacent foot pad. The tops of the first cross member and the second cross member of the rear cross member assembly are respectively operatively rotatably connected to joints of the fourth rod.
In an embodiment, the two groups of connecting rod assemblies are symmetrically arranged. The first rod, the third rod, the first connecting rod and the fifth rod in one group of the connecting rod assembly are symmetrically arranged with the second rod, the fourth rod, the second connecting rod and the sixth rod within each connecting rod assembly and from one connecting rod assembly to the laterally opposite connecting rod assembly.

In the expanded configuration of the frame, the first rod 1 and the second rod 2 form an inverted V-shape.
The bottom of the fifth rod 5 may be rotatably connected with the bottom of the first rod 1, the bottom of the sixth rod 6 may be rotatably connected with the bottom of the second rod 2. In the expanded configuration of the frame, the fifth rod 5 and the sixth rod 6 extend outward from bottom to top, that is, the first rod 1, the second rod 2, the fifth rod 5 and the sixth rod 6 may be connected to form a W shape, and can be symmetrically arranged.
The bottom of the third rod 3 may be rotatably connected with the bottom of the fourth rod 4. In the expanded configuration of the frame, the third rod 3 and the fourth rod 4 form a V shape and can be symmetrically arranged. The middle part of the third rod 3 may be rotatably connected with the middle part of the first rod 1, the middle part of the fourth rod 4 may be rotatably connected with the middle part of the second rod 2. The top connection shared by the first rod 1 and the second rod 2 may be located vertically above the bottom connection shared by the third rod 3 and the fourth rod 4. In this way, the first rod 1, the second rod 2, the third rod 3, the fourth rod 4, the fifth rod 5 and the sixth rod 6 can be unfolded and folded synchronously.
A first positioning groove 51 may be provided on the fifth rod 5, and a second positioning groove 61 may be provided on the sixth rod 6. The first positioning groove 51 can be a metal pipe fitting, and may include a clamp sleeved on the fifth rod 5 with an integral groove body for supporting a first connecting rod 31. The integral groove body may be located lateral inward or toward the inside of the fifth rod 5.
Similarly, the second positioning groove 61 may include a clamp sleeved on the sixth rod 6 with an integral groove body for supporting the second connecting rod 41. The integral groove body may be located laterally inward or toward the inside of the sixth rod 6.
A first connecting rod 31 has one end rotatably connected to the top of the third rod 3 at a joint 35 and an opposite end rotatably connected to the fifth rod 5. A second connecting rod 41 has one end rotatably connected to the top of the fourth rod 4 at a joint 45, and an opposite end rotatably connected to the sixth rod 6. The first connecting rod 31 and the second connecting rod 41 may be symmetrically arranged on the hammock frame (HF).
When the hammock frame (HF) is in the unfolded or expanded state, the first connecting rod 31 is snapped and fixed into the first positioning groove 51, and the second connecting rod 41 is snapped and fixed into the second positioning groove 61.
It can be seen that, the first positioning groove 51 and the second positioning groove 61 limit the first connecting rod 31 and the second connecting rod 41, and prevent the first connecting rod 31 and the second connecting rod 41 from moving beyond the limit position.
When folding is required, referring to
In order to fix the position between the two groups of connecting rod assemblies, a traverse brace member 9 can be arranged between the tops of the two fifth rods 5 of the connection rod assemblies and/or the tops of the two sixth rods 6 of the connection rod assemblies. The traverse brace member 9 may be detachable relative to the fifth rods 5 and/or sixth rods 6. The tops of the two fifth rods 5 of the connection rod assemblies and/or the tops of the two sixth rods 6 of the connection rod assemblies may have sockets adapted to receive an end of the transverse brace member 9. Accordingly one or two traverse brace members 9 may be provided with the hammock frame (HF).

The sleeves may be adjusted so that the hole of the inner sleeve comes into register with a desired hole of the different holes of the outer sleeve, and a pin or screw may be inserted into two holes to fix the height of the adjusting member 10. In another aspect, a spring loaded protrusion extending out of the inner sleeve may be engageable with a desired hole of the different holes of the outer sleeve. The ceiling member 12 and the sleeve member 13 may be arranged to rotate around the top of the supporting member 11, so as to adjust the shading angle. For at the nesting mode of the two sleeves, it is also possible to adopt a fitting mode such as the engagement of a spring pin with a groove, and the spring pin is inserted into the groove to fix the two sleeves, and when the two sleeves need to be separated, the spring pin can be detached from the groove. Furthermore, the shading area can be adjusted by the sliding of the sleeve member 13 relative to the ceiling member 12. The sleeve member and ceiling member may have an arrangement similar to the adjusting member that allows the sleeve member and the ceiling member to be adjustably fixable relative to each other.
The sunshade (SS) may also include a supporting bar 14 arranged between the two sleeve members 13, so that the position between the two sleeve members 13 is fixed, thereby realizing a reliable shading effect. The number of the supporting bar 14 can be four, and the four supporting bars 14 are collinear in pairs, two supporting bars 14 collinearly arranged are rotatably connected, and all four supporting bars 14 are rotatably connected to the sleeve members 13, as shown in
The bottoms of the adjusting member 10 and the supporting member 11 may be rotatably connected to the top of the fifth rod 5, so as to further adjust the shading angle. The adjusting member 10 and the supporting member 11 may be mounted on the fifth rod 5, which is convenient to carry and store. When the sunshade is folded, the sunshade may also be temporarily fixed to the fifth rod 5 with a strap.
