Description

Technical Field

[0001] The present application relates to the technical field of folding tables and chairs, and in particular to a folding flat chair. Background Art

[0002] In order to facilitate outdoor travel and carrying, folding tables and chairs are becoming more and more common in the market. Among them, the main folding and storage method is to rotate the legs. Among them, the main method of rotating storage is to insert a hinge bolt through the legs of the table and chair, and the hinge bolt is fixed on the bracket. When rotating and storing, the legs of the table and chair rotate with the hinge bolt as the rotation axis.

[0003] With respect to the above-mentioned related technologies, the inventors have found the following defects: First, when the hinge bolt is used as the rotation axis, the hinge bolt will also be the force point, and the weight will be concentrated on the hinge bolt. Over a long period of time, the hinge bolt will be deformed, making the overall structural strength and stability of the table and chair poor. If the hinge bolt is only used as the rotation axis, the top of the table and chair leg needs to support the bracket at this time, so that the top of the leg is directly stressed. This method will limit the mutual position of the legs and the bracket of the table and chair, so that the rotation of the legs is restricted and it is not easy to rotate. Second, simply using hinge bolts will make the state of the legs unstable, and it is easy to change from the non-storage state to the storage state, or from the storage state to the non-storage state. That is, it is difficult for existing tables and chairs to simultaneously ensure the strength and stability of the supporting structure, the quick and convenient storage of the legs, and the stability of the leg state.

[0035] The following is combined with Figure 1-8 This application is described in further detail.

[0036] The embodiment of the present application discloses a folding lie-flat chair.

[0037] Reference Figure 1 and Figure 2The folding reclining chair comprises a skeleton structure 1, a support portion 6 arranged above the skeleton structure 1, and a plurality of support legs 7 arranged below the skeleton structure 1. The skeleton structure 1 comprises a plurality of first support cross bars 2, second support cross bars 3, support top bars 4, and connecting members 5. In this embodiment, four connecting members 5 are provided, two first support cross bars 2 are provided, two second support cross bars 3 are provided, four support top bars 4 are provided, and four connecting members 5 and support legs 7 are also provided. The support portion 6 adopts a cloth structure, and insertion holes 65 are provided at the four corners of the support portion 6. The support portion 6 is installed on the support top bar 4 by inserting the top end of the support top bar 4 into the insertion hole 65 on the support portion 6.

[0038] Reference Figure 3 The support portion 6 is integrally connected with a storage member 61 for loading objects. In this embodiment, two storage members 61 are provided, one is a cloth bag for placing documents and other articles, and the other is a cup bag for placing a cup. A storage bag 62 is provided at the rear of the support portion 6. Specifically, a first connection cloth 63 is provided on the support portion 6, and a second connection cloth 64 is provided on the storage bag 62. The first connection cloth 63 and the second connection cloth 64 are connected by a zipper, so as to realize a detachable connection of the storage bag 62.

[0039] Reference Figure 4 and Figure 5 The connecting member 5 is provided with a first fixing hole 51 for inserting the first supporting cross bar 2, a second fixing hole 52 for inserting the second supporting cross bar 3, a third fixing hole 53 for inserting the supporting top rod 4, and a rotating channel 54 for the supporting leg 7 to be rotatably embedded.

[0040] Reference Figure 5 and Figure 6 The support leg 7 is provided with an articulated bolt 71 that is rotatably inserted into the connecting member 5, and the support leg 7 is provided with a waist-shaped hole 72 for the articulated bolt 71 to slide through. An elastic rope 73 is inserted into the support leg 7, one end of the elastic rope 73 is connected to the bottom of the support leg 7, and the other end is connected to the connecting member 5. The support leg 7 has a supporting state and a storage state. When the folding reclining chair is used, the support leg 7 is in the supporting state. At this time, under the elastic force of the elastic rope 73, the top of the support leg 7 is pressed against the connecting member 5. When the support leg 7 needs to be transformed into a folded state, the support leg 7 needs to be pulled downward to make the hinge bolt 71 slide in the waist-shaped hole 72. At this time, the top of the support leg 7 is no longer pressed against the connecting member 5. Then the support leg 7 is rotated to transform the support leg 7 into a stored state. At this time, the support leg 7 is pulled away from the connecting member 5. The hinge bolt 71 slides relatively in the waist-shaped hole 72. Under the action of the elastic rope 73, the top of the support leg 7 is pressed against the connecting member 5 again, making it difficult for the support leg 7 to be transformed into a supporting state.

[0041] Reference Figure 5and Figure 6 Furthermore, a first positioning groove 55 is provided in the connecting member 5. When the supporting leg 7 is in the supporting state, the top end of the supporting leg 7 is embedded in the first positioning groove 55, so that the position of the supporting leg 7 in the supporting state is more stable. One end of the elastic rope 73 is fixed to the bottom of the first positioning groove 55. The specific fixing method can be a rope knotting method. For example, a ring is provided on the bottom of the first positioning groove 55 for the elastic rope 73 to pass through and be knotted; or the end of the elastic rope 73 is wound and fixed on a screw, and then the screw is threadedly connected in the first positioning groove 55.

[0042] Reference Figure 5 and Figure 6 At the same time, a second positioning groove 56 is also provided on the connecting member 5. When the supporting leg 7 is in the storage state, under the elastic action of the elastic rope 73, the end of the supporting leg 7 is pressed into the second positioning groove 56, so that the position of the supporting leg 7 in the storage state is more stable.

[0043] Reference Figure 6 and Figure 7 The support leg 7 includes a rotating rod 74 and a fixed leg 75 slidably sleeved on the rotating rod 74, and a waist-shaped hole 72 is provided on the rotating rod 74. An elastic member 76 is provided in the rotating rod 74, and a plunger head 761 is provided on the elastic member 76. A first through-hole 741 is provided on the rotating rod 74, and a second through-hole 751 is provided on the fixed leg 75. The elastic member 76 has elastic potential energy to press the plunger head 761 into the first through-hole 741 and the second through-hole 751. When the rotating rod 74 and the fixed leg 75 need to be separated from each other, it is only necessary to press the plunger head 761 to withdraw the plunger head 761 from the first through-hole 741 and the second through-hole 751. In this embodiment, two second through-holes 741 are provided to facilitate the adjustment of the length of the support leg 7. The elastic member 76 is a bent metal strip.

[0044] Reference Figure 6 It is worth noting that a connecting buckle 752 for connecting to the end of the elastic rope 73 is provided at the bottom of the fixed leg 75. Before separating the fixed leg 75 and the rotating rod 74 from each other, the elastic rope 73 needs to be removed from the connecting buckle 752.

[0045] Reference Figure 6 The bottom of the fixed leg 75 is sleeved with an abutment ball 77, and when the folding flat chair is in use, the abutment ball 77 can directly contact the ground. In this embodiment, a support foot pad 78 is provided at the bottom of the abutment ball 77, and an embedding groove 781 for the abutment ball 77 to embed is provided on the support foot pad 78.

[0046] Reference Figure 8Since the support part 6 in this embodiment is tilted, the support top rod 4 at the rear is longer. The support top rod 4 includes a first support tube 41 and a second support tube 42, and the first support tube 41 and the second support tube 42 are slidably plugged. The end of the first support tube 41 away from the second support tube 42 is provided with a connecting cap 43. The first support tube 41 and the second support tube 42 are provided with a fixed elastic rope 44. One end of the fixed elastic rope 44 is connected to the connecting cap 43, and the other end is connected to the connecting piece. When folding the support top rod 4, it is only necessary to pull the support top rod 4 out of the third fixing hole 53, and then fold the support top rod 4.

[0047] The implementation principle of a foldable lying flat chair in the embodiment of the present application is as follows: when folding and storing the support leg 7, pull the support leg 7 downward to make the hinge bolt 71 slide relatively in the waist-shaped hole 72, and the top of the support leg 7 withdraws from the first positioning groove 55, and then rotate the support leg 7; when the support leg 7 is rotated to the folded state, loosen the support leg 7, and under the elastic force of the elastic rope 73, the end of the support leg 7 is embedded in the second positioning groove 56, so that the position of the support leg 7 in the storage state is more stable. When storing the skeleton structure 1, it is only necessary to first remove the support part 6 from the support top rod 4, and then remove the second support cross rod 3 and the support top rod 4 from the connecting member 5, and then fold and place it.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
