Description

Technical Field

[0001] This application relates to the field of reclining bed technology, and in particular to a folding reclining bed. Background Technology

[0002] As a type of leisure furniture, reclining beds are widely used in homes, resorts, beaches, and outdoor recreational areas, providing users with a comfortable resting experience. The core of their design lies in offering an adjustable sitting or reclining posture to accommodate different user relaxation needs.

[0003] To adapt to different usage needs, existing recliners are often designed with folding mechanisms. However, most existing folding structures are fixed by hinges and locking pins. Such folding mechanisms are too cumbersome to operate and require precise alignment, resulting in a poor user folding experience. Although there are folding structures on the market that can lock and unlock, they often use easily damaged components such as springs. Therefore, the purpose of this application is to solve the above problems.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, this application provides a folding recliner to solve one of the aforementioned technical problems.

[0006] The technical solution adopted by this application to solve its technical problem is a folding recliner, including: a main support and legs, which are rotatably connected by a first connecting part and a second connecting part that are hinged to each other. The second connecting part has a limiting hole with a non-circular outline. A locking mechanism includes a cylindrical locking pin and a first limiting part formed on the outer periphery of the cylindrical locking pin and complementary in shape to the limiting hole. The cylindrical locking pin can only move axially within the second connecting part. When the first limiting part is inserted into the limiting hole by sliding the cylindrical locking pin, the second connecting part is prevented from rotating. The second limiting part can be disengaged from the limiting hole by axially driving the cylindrical locking pin to achieve unlocking.

[0007] In some embodiments, the locking mechanism further includes a second limiting portion rotatably disposed at the end of the locking mechanism, wherein a movable groove is provided on one side of the first connecting portion, and the second limiting portion is capable of rotating and sliding in the second limiting portion.

[0008] In some embodiments, at least one axial positioning groove is provided on the outer periphery of the movable groove, and a rotation positioning groove is provided on the outer side of the axial positioning groove, and a positioning block is provided on the second limiting part that can cooperate with the rotation positioning groove and the axial positioning groove.

[0009] In some embodiments, the thickness of the second limiting portion is greater than the depth of the rotating positioning groove.

[0010] In some embodiments, the cross-section of the first limiting portion is polygonal, and the diameter of the cylindrical locking pin is less than or equal to the inscribed circle of the cross-section of the first limiting portion.

[0011] In some embodiments, the first connecting portion is a double lug, the second connecting portion is a single lug, and the second connecting portion is clamped by the first connecting portion.

[0012] In some embodiments, a backrest is rotatably mounted on the main support, the backrest being provided with a backrest bracket capable of fixing the rotation angle of the backrest, and the backrest bracket being provided with serrations that can engage with the main support.

[0013] In some embodiments, the main support is provided with a locking buckle and a locking part, and the locking buckle can engage with the locking part in the folded state.

[0014] The beneficial effects of this application are as follows: by cooperating with the locking mechanism and the limiting hole under different usage requirements, the locking mechanism can move to put the first connecting part and the second connecting part into a locked state or a movable state. At the same time, this application can restrict the axial movement of the locking pin through the axial positioning groove and the rotation positioning groove to prevent the limiting hole from separating from the first limiting part due to negligence.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0026] In the embodiments of this application, please refer to Figure 1-8 As shown, this application provides a folding recliner, mainly comprising: a main support 1 and legs 2, which are rotatably connected by a first connecting part 11 and a second connecting part 21 hinged to each other. The second connecting part 21 has a limiting hole 211 with a non-circular outline. A locking mechanism 3 includes a cylindrical locking pin 31 and a first limiting part 311 formed on the outer periphery of the cylindrical locking pin 31 and complementary in shape to the limiting hole 211. The cylindrical locking pin 31 can only move axially within the second connecting part 21. When the first limiting part 311 is inserted into the limiting hole 211 by sliding the cylindrical locking pin 31, the second connecting part 21 is prevented from rotating. The second limiting part 32 can be disengaged from the limiting hole 211 by axially driving the cylindrical locking pin 31 to achieve unlocking.

[0027] Specifically, due to its cylindrical nature, the cylindrical locking pin 31 allows the second connecting part 21 to rotate freely within its rotatable range when the cylindrical part of the cylindrical locking pin 31 is completely within the range of the limiting hole 211, while the first limiting part 311 is completely or at least partially within the range of the limiting hole 211 and can cooperate with the limiting hole 211 to allow the second connecting part 21 to rotate.

[0028] Reference Figure 5-6 As shown, when it is necessary to change the first connecting part 11 and the second connecting part 21 from the locked state to the movable state, the first limiting part 311 is located within the range of the limiting hole 211. By pressing the side away from the first limiting part 311, the first limiting part 311 is completely disengaged from the range of the limiting hole 211, and the first connecting part 11 and the second connecting part 21 enter the movable state. When it is necessary to change the first connecting part 11 and the second connecting part 21 from the movable state to the locked state, the first limiting part 311 is located outside the range of the limiting hole 211. By aligning the outline of the first limiting part 311 and the limiting hole 211, and pressing the side of the cylindrical locking pin 31 near the first limiting part 311, the first limiting part 311 enters the range of the limiting hole 211.

[0029] Preferably, the cylindrical locking pin 31 is formed on the second connecting part 21 through the second connecting part 21 or additionally as a non-circular component, and one side of the first connecting part 11 is also formed with a hole or groove for limiting its contour, so that the cylindrical locking pin 31 will not rotate synchronously during the rotation of the second connecting part 21, thus affecting the reset of the cylindrical locking pin 31.

[0030] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0031] Reference Figure 4 As shown, the locking mechanism 3 further includes a second limiting part 32 rotatably disposed at the end of the locking mechanism 3. A movable groove 111 is provided on one side of the first connecting part 11, and the second limiting part 32 can rotate and slide. At least one axial positioning groove 112 is provided on the outer periphery of the movable groove 111, and a rotating positioning groove 113 is provided on the outer side of the axial positioning groove 112. The second limiting part 32 is provided with a positioning block 321 that can cooperate with the rotating positioning groove 113 and the axial positioning groove 112. With this configuration, the positioning block 321 on the rotatable second limiting part 32 is normally located on the rotating positioning groove 113. At this time, the first limiting part 311 is located within the range of the limiting hole 211. By rotating the second limiting part 32, the positioning block 321 rotates in the rotating positioning groove 113 and rotates to the range of the axial positioning groove 112. At this time, the second limiting part 32 can be pressed, so that the second limiting part 32 enters the bottom end of the movable groove 111, and the first limiting part 311 is pushed out of the range of the limiting hole 211, so that the first connecting part 11 and the second connecting part 21 can rotate.

[0032] Preferably, in order to allow at least a portion of the second limiting part 32 to extend beyond the first connecting part 11 so that the user can rotate the second limiting part 32, the thickness of the second limiting part 32 is greater than the depth of the rotation positioning groove 113.

[0033] Specifically, in order to enable the limiting hole 211 to restrict the rotation of the first limiting part 311 and ensure that it does not affect the rotation of the cylindrical locking pin 31, the cross-section of the first limiting part 311 is polygonal, and the diameter of the cylindrical locking pin 31 is less than or equal to the inscribed circle of the cross-section of the first limiting part 311. The more sides of the polygon, the more angles that the first connecting part 11 and the second connecting part 21 can rotate and lock.

[0034] Preferably, in order to optimize the rotational connection between the first connecting part 11 and the second connecting part 21 and to facilitate the opening of a slot that allows the cylindrical locking pin 31 to move axially only on the first connecting part 11, the first connecting part 11 has a double lug, the second connecting part 21 has a single lug, and the second connecting part 21 is clamped by the first connecting part 11.

[0035] Reference Figure 1 As shown, in order to facilitate the reclining chair, a backrest 4 is also included, which is rotatably mounted on the main support 1. The backrest 4 is provided with a backrest bracket 41 that can fix the rotation angle of the backrest 4. The backrest bracket 41 is provided with serrations 411 that can be engaged with the main support 1.

[0036] Reference Figure 2 As shown, in order to prevent the folding recliner from unfolding due to external forces such as moving the recliner when it is in the locked state, the main support 1 is provided with a locking buckle 13 and a locking part 12. The locking buckle 13 can engage with the locking part 12 when the recliner is folded.
