Description

FIELD OF THE INVENTION

The present invention belongs to the field of leisure goods, in particular to a folding hammock.

TECHNICAL BACKGROUND

A hammock is a common outdoor leisure item, which can be hung directly on a fixed object without a bracket; The other type comes with a foldable bracket that can be supported on flat ground; On this basis, there are two types of suspension points: double suspension points and single suspension points at both ends. The plan with dual suspension points at both ends of the built-in bracket and flexible bed surface is not only convenient to use but also relatively safe, and is widely popular among the public.

For example: CN202020271476.X, a foldable hammock is disclosed, which includes a bed surface and a bed frame. The bed surface is arranged on the bed frame, and the bed frame includes two sets of upright poles arranged in pairs, two sets of side cross connecting rod groups arranged in parallel intervals, and two sets of middle cross connecting rod groups arranged in parallel intervals; Each group of side cross connecting rod groups can be pivotally connected to adjacent two upright rods, and each group of side cross connecting rod groups includes two side connecting rods that are pivotally connected together in the middle. The side connecting rods include a lower long rod and an upper short rod that can be pivotally connected together at the adjacent ends. A middle pivotable connecting piece is pivotally connected between the two lower long rods of each group of side cross connecting rod groups below the connection point of the two lower long rods; The two upper endpoints of the cross connecting rod group in each group can be pivotally connected to the connection between the two opposite long rods and the upper short rods, and the two lower endpoints of the cross connecting rod group in each group can be pivotally connected to the lower part of the bed frame. In this scheme, the lower end of the vertical pole used to suspend the bed surface directly touches the ground at both ends, effectively guiding the force into the ground. The internal force bearing at the top of the vertical pole is supported by the connecting rod groups on both sides. In order to achieve folding, the side connecting rod group is connected by a long rod and a short rod, resulting in insufficient stability of the support.

How to provide a more reasonable technical solution becomes the research object of the present invention.

SUMMARY OF THE INVENTION

The purpose of the present invention is to design a foldable hammock with two side support rod groups that can directly guide the force into the ground.

DETAILED DESCRIPTION

Referring to FIGS. 1 to 11, the folding hammock includes a support 100 and a flexible bed surface 200, which can be hung on the support 100 to form a usable hammock.

Support 100, including landing rod group 1 and support rod group 2 on both sides, as well as associated rod group 3 related to the support rod groups on both sides; The arrows in FIGS. 1, 2, and 4 indicate the side of the hammock. Among them:

The landing rod group 1 includes two cross hinged landing rods 11, with the hinge point 12 of the two landing rods located above the center point of the rod. The hinge point 12 divides the upper shorter support section 111 and the lower longer and end landing section 112, as shown in FIG. 7; A clamping component 4 is arranged between the end of the open support section 111 and the landing section 112 of another landing rod, forming an associated constraint between the two landing rods 11; That is to say, the ground rod group 1 is opened in place, and the end of the support section 111 is clamped and constrained with the landing section 112, and the landing support point is added with the help of this clamping component.

Support rod group 2 is arranged at both ends of landing rod group 1, which includes main support rod 21 and auxiliary support rod 22. The lower end of main support rod 21 is hinged at the end of landing section 112 of the landing rod, and the upper end is suspended to hang flexible bed surface 200; The upper end of the auxiliary support rod 22 is hinged to the middle of the main support rod 21, and the lower end is hinged to the end of the support section 11 of another landing rod. More specifically, it is hinged to the clamping component 4 at the end of the support section. In this structure, the auxiliary support rod 22 is located on the inner side of the main support rod 21, which can prevent the main support rod 21 from bearing weight and force and then retract inward. With the help of the auxiliary support rod 22, a portion of the force is transmitted to the landing rod group 1 through the clamping component 4 and introduced into the ground, as shown in FIG. 7.

Associated rod group 3, including two cross hinged rods 31 in the middle. The lower ends of the two rods 31 are correspondingly hinged at the lower ends of the main support rods 21 on both sides, and the upper ends are correspondingly hinged at the middle of the auxiliary support rods 22 on both sides. Realize the association between the two support rod groups on both sides, and maintain the open state of the constraint bracket, as well as provide action associations for the opening and folding processes, as shown in FIG. 1, FIG. 2, and FIG. 4.

The clamping component 4 includes an upper plastic component 41 and a lower plastic component 42. The upper plastic component 41 is horizontally formed with a blind hole 411 for inserting and riveting the end of the ground rod support section 111, and the lower end surface is formed with a downward facing tenon 412; More specifically, the upper plastic part is also formed with a hinge groove 413 on one side of the blind hole 411 to hinge the auxiliary support rod. The upper end of the landing rod support section 111, the end of the auxiliary support rod 22, and the upper plastic part 41 are riveted together with a rivet 5, and the auxiliary support rod 22 is allowed to swing around the rivet 5 to complete the folding action, as shown in FIGS. 1, 3, 6, and 11.

The lower plastic part 42 is horizontally formed with a through hole 421 for the landing section 112 of the ground rod to pass through, a slot 422 for the insertion and engagement of the convex tenon 412 on the upper end surface, and a landing flat bottom 423 that can be stably supported on the ground is formed on the lower end surface; Furthermore, the through holes 421 and card slots 422 on the lower plastic part are misaligned on both sides. The through holes 421 are located below the forward projection of the hinge slot 412 on the upper plastic part, the card slots 422 are located below the forward projection of the blind hole 411, and the landing flat bottom 423 is located directly below the through hole 421. A support foot 424 that can land is also set on one side of the corresponding card slot 422, which together forms a landing support and increases the landing area and range, as shown in FIGS. 6 and 11.

Due to the design gap between the end of the support section 111 and the landing section 112 of the other one after the two landing rods 11 are opened, the lower plastic part 42 can be appropriately raised, and the raised part cannot occupy the folded space. Therefore, a storage groove 425 is formed above the through-hole of the lower plastic part 42, and card grooves 422 are set on both sides of the groove walls of the storage groove 425 to achieve balanced support on both sides; The tenon 412 and slot 422 are both wedge-shaped and can be easily inserted during the opening process, with a certain tolerance. As shown in FIG. 10, the bracket is folded in place, and the storage slot 425 can be accessed by the main support rod 21 on the same side to avoid obstructing the assembly and folding of the rod components.

Furthermore, a triangular seat 6 is arranged at the hinge joint between the middle of the main support rod 21 and the end of the auxiliary support rod 22, and a right angle seat 7 is arranged at the hinge joint between the end of the main support rod 21 and the end of the landing rod 11. With the help of the triangular seat 6, the right angle seat 7, and the clamping component 4, the landing section 112 of the auxiliary support rod 22, the main support rod 21, and the landing rod 112 are kept in the same plane, opened in place to form a triangular structure, forming a stable support. The load-bearing force at the upper end of the main support rod 21 can be directly introduced into the ground through the auxiliary support rod 22 and the clamping component 4 in the same plane, in collaboration with the right angle seat 7 at the end of the main support rod, forming a common landing support. The above triangular seat 6 and right angle seat 7 are only for naming purposes and are not limited to their specific shapes.

The flexible bed surface 200 of this hammock is a four corner suspension structure, and there are no flipping defects during use. More specifically, the flexible bed surface 200 is sewn with fabric sleeves 201 at both ends, and a tension rod 202 is threaded through the fabric sleeve. The two ends of the tension rod 202 are hung with hanging chains 203, which are hung on the hanging plastic part 211 at the top of the main support rod 21 with the help of hanging chains 203; The hanging plastic component 211 is formed into a rod sleeve that can be fixed at the end of the main support rod, and a supporting ring platform 212 is extended along the lower edge of the rod sleeve. The area of the supporting ring platform 212 is larger than the area of the hanging ring 204 at the end of the hanging chain 203, forming a suspension force limiting effect. When folding, the flexible bed surface 200 can be wrapped and folded up according to the tension rods 202 at both ends, and loaded into a storage bag together with the folded bracket 100.

During the opening and folding process of bracket 100, as shown in FIGS. 7, 8, and 9, the landing rod group 1 and the support rod group 2 form a double quadrilateral structure. When opened, both hands open the upper end of the main support rod 21 outward, and the landing rod group 1 synchronously drives it to unfold. From the state in FIG. 9 to the state in FIG. 8, continue to manually press down on the upper plastic part 41 to flip the auxiliary support rod 22 downward over the interference point, until the upper plastic part 41 and the lower plastic part 42 snap in place, as shown in the state in FIG. 7, Then hang the flexible bed surface 200; When folding, it is necessary to lift the upper plastic part 41 to flip the auxiliary support rod 22 and close the main support rod 21, etc.
