Description

Technical field:

[0001] The invention belongs to the field of leisure products, and in particular relates to a folding hammock. Background technology:

[0002] Hammocks are a common outdoor leisure product. One type is without a bracket and is directly hung on a fixed object; the other type is with a foldable bracket that can be supported on flat ground; on this basis, there are two types with double hanging points at both ends and single hanging points. The solution with a built-in bracket and double hanging points at both ends of the flexible bed surface is not only convenient to use but also relatively safe, and is widely popular among the public.

[0003] For example: CN202020271476.X discloses a foldable hammock, comprising a bed surface and a bed frame, the bed surface being arranged on the bed frame, the bed frame comprising two groups of vertical poles spaced in pairs, two groups of side cross-connecting rod groups spaced in parallel, and two groups of middle cross-connecting rod groups spaced in parallel; each group of side cross-connecting rod groups can be pivotally connected to two adjacent vertical poles, each group of side cross-connecting rod groups includes two side connecting rods pivotally connected together in the middle, the side connecting rods include a lower long rod and an upper short rod pivotally connected together at 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 between the two lower long rods; the two upper end points of each group of middle cross-connecting rod groups can be pivotally connected to the connection between the two opposite lower long rods and the upper short rod, and the two lower end points of each group of middle cross-connecting rod groups can be pivotally connected to the bottom of the bed frame. In this solution, the lower ends of the vertical rods at both ends used to suspend the bed surface directly touch the ground, which can effectively guide the force to the ground, and the inward force of the load-bearing top of the vertical rod is supported by the connecting rod groups on both sides. In order to achieve folding, the connecting rod group on the side is connected by a long rod and a short rod, resulting in insufficient stability of the support.

[0004] How to provide a more reasonable technical solution becomes the research object of the present invention. Summary of the invention:

[0005] The purpose of the invention is to design a folding hammock with support rod groups on both sides capable of directly introducing the force into the ground.

[0040] Reference Figures 1 to 11 The folding hammock comprises a bracket 100 and a flexible bed surface 200. The flexible bed surface 200 can be hung on the bracket 100 to form a usable hammock.

[0041] The bracket 100 includes a ground rod group 1 and a support rod group 2 on both sides, and an associated rod group 3 associated with the support rod groups on both sides; Figure 1 , Figure 2 and Figure 4 The middle arrow indicates the side of the hammock.

[0042] The ground rod set 1 includes two ground rods 11 cross-hinged together, and the hinge point 12 of the two ground rods is above the center point of the rod. The hinge point 12 divides the upper shorter support section 111 and the lower longer ground section 112 with the end touching the ground. Figure 7 ; A snap-fit ​​assembly 4 is provided between the end of the support segment 111 opened into place and the grounding segment 112 of another grounding rod, forming an associated constraint between the two grounding rods 11; that is to say, when the grounding rod group 1 is opened into place, the end of the support segment 111 is snap-fitted and constrained with the grounding segment 112, and the grounding support point is increased with the help of the snap-fit ​​assembly.

[0043] The support rod group 2 is arranged at both ends of the ground rod group 1, and includes a main support rod 21 and a secondary support rod 22. The lower end of the main support rod 21 is hinged to the end of the ground section 112 of the ground rod, and the upper end is suspended to suspend the flexible bed surface 200; the upper end of the secondary 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 ground rod, more specifically, it is hinged to the snap-fit ​​assembly 4 at the end of the support section. In this structure, the secondary support rod 22 is located on the inner side of the main support rod 21, which can prevent the main support rod 21 from retracting after bearing weight, and with the help of the secondary support rod 22, part of the force is transmitted to the ground rod group 1 through the snap-fit ​​assembly 4 and introduced into the ground, such as Figure 7 .

[0044] The associated rod group 3 includes two rods 31 with cross hinges in the middle. The lower ends of the two rods 31 are correspondingly hinged to the lower ends of the main support rods 21 on both sides, and the upper ends are correspondingly hinged to the middle of the secondary support rods 22 on both sides. The association between the support rod groups 2 on both sides can be achieved, and the opening state of the bracket can be maintained and constrained, and the action association is also provided for the opening and folding process. Figure 1 , Figure 2 and Figure 4 .

[0045] The clamping assembly 4 includes an upper plastic part 41 and a lower plastic part 42. The upper plastic part 41 is formed with a blind hole 411 for the end of the grounding rod support section 111 to be inserted and riveted, and a downwardly facing tenon 412 is formed on the lower end surface; more specifically, the upper plastic part is further formed with a hinge groove 413 for hingedly connecting the auxiliary support rod on one side of the blind hole 411, and the upper end of the grounding rod support section 111, the end of the auxiliary support rod 22 and the upper plastic part 41 are riveted together by a rivet 5, and the auxiliary support rod 22 is allowed to swing around the rivet 5 so as to be lifted up to complete the folding action, such as Figure 1 , Figure 3 , Figure 6 and Fig.11 .

[0046] The lower plastic part 42 is formed with a through hole 421 for the grounding section 112 of the grounding rod to pass through, a slot 422 for the tenon 412 to be inserted and engaged on the upper end surface, and a grounding flat bottom 423 that can be stably supported on the ground is formed on the lower end surface; further, the through hole 421 and the slot 422 on the lower plastic part are staggered and arranged on both sides, the through hole 421 is below the positive projection of the hinge groove 412 of the upper plastic part, the slot 422 is below the positive projection of the blind hole 411, and the grounding flat bottom 423 is directly below the through hole 421, and a support leg 424 that can touch the ground is also arranged on one side of the corresponding slot 422, and the support leg 424 and the grounding flat bottom 423 together form a grounding support, thereby increasing the grounding area and range, such as Figure 6 and Fig.11 .

[0047] After the two grounding rods 11 are opened, there is a designed distance between the end of the support section 111 and the grounding section 112 of the other rod, so the lower plastic part 42 can be appropriately raised, and the raised height cannot occupy the space after folding. Therefore, a storage groove 425 is formed above the through hole of the lower plastic part 42, and a clamping groove 422 is provided on the groove walls on both sides of the storage groove 425 to achieve balanced support on both sides; the tenon 412 and the clamping groove 422 are wedge-shaped, which can be easily inserted during the opening process and has a certain tolerance. Fig.10 When the bracket is folded into place, the storage groove 425 can be used for the main support rod 21 on the same side to enter, avoiding obstruction of the rods from being bundled and folded.

[0048] Furthermore, a triangular seat 6 is arranged at the hinged part between the middle part of the main support rod 21 and the end part of the auxiliary support rod 22, and a right-angle seat 7 is arranged at the hinged part between the end part of the main support rod 21 and the end part of the ground rod 11. With the help of the triangular seat 6, the right-angle seat 7 and the snap assembly 4, the auxiliary support rod 22, the main support rod 21 and the ground section 112 of a ground rod are kept in the same plane, and a triangular structure is formed when the part is opened to form a stable support. The load-bearing force at the upper end part of the main support rod 21 can be directly introduced into the ground in the same plane through the auxiliary support rod 22 and the snap assembly 4, etc., and cooperate with the right-angle seat 7 at the end part of the main support rod to form a common ground support. The above-mentioned triangular seat 6 and right-angle seat 7 are only for naming needs and are not limited to their specific shapes.

[0049] The flexible bed surface 200 of the hammock is a four-corner suspension structure, and there is no overturning defect when in use. More specifically, cloth covers 201 are sewn at both ends of the flexible bed surface 200, and a tension rod 202 is inserted in the cloth cover. Hanging chains 203 are hung at both ends of the tension rod 202, and the hanging chain 203 is used to hang on the hanging plastic part 211 at the top of the main support rod 21; the hanging plastic part 211 is formed with a rod sleeve that can be fixed on the end of the main support rod, and a support ring platform 212 is extended outward from the lower edge of the rod sleeve. The area of ​​the support 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 folded, the flexible bed surface 200 can be rolled up according to the tension rods 202 at both ends, and put into a storage bag together with the folded bracket 100.

[0050] The process of opening and folding the bracket 100 is as follows: Figure 7 , Figure 8 and Fig. 9 The ground rod group 1 and the support rod group 2 form a double quadrilateral structure. When opening, both hands push the upper end of the main support rod 21 outward, and the ground rod group 1 drives the main support rod 21 to unfold synchronously. Fig. 9 Status to Figure 8 In this state, continue to manually press down the upper plastic part 41 to make the auxiliary support rod 22 flip downward over the interference point until the upper plastic part 41 and the lower plastic part 42 are engaged in place. Figure 7When folding, the upper plastic part 41 needs to be lifted to turn the auxiliary support rod 22 over and close the main support rod 21, etc.
