With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.
[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0027] Example 1
[0028] Reference Figures 1 to 6 Example 1 provides a beach chair for outdoor sports.
[0029] like Figure 1 and Figure 2 As shown, the beach chair in this embodiment includes a chair fabric 1 and a leisure chair frame with unlimited adjustment (hereinafter referred to as the chair frame).
[0030] The chair frame in this embodiment includes armrest tubes 2, seat tubes 3 (i.e., seat), front leg tubes 4, rear leg tubes 5, backrest tubes 6, and support leg tubes 7 rotatably connected to the backrest tubes 6. A chair fabric 1 is fitted onto the seat tubes 3 and backrest tubes 6. When unfolded, the support leg tubes 7 provide support on the ground and effectively support the backrest tubes 6, thus enabling the beach chair to be transformed into a chair like... Figure 2 The recliner is shown in its current state. Of course, armrest tube 2 is fitted onto the armrest sleeve to enhance comfort and overall aesthetics.
[0031] The chair frame in this embodiment also includes a stopless adjustment mechanism 8, which includes an elastic reset member, a slidable connecting seat 82 sleeved on the armrest tube 2, a rack 83 fixedly connected to the bottom of the armrest tube 2, and a locking assembly 84 provided on the connecting seat 82.
[0032] The upper end of the rear leg tube 5 is rotatably connected to the front leg tube 4, the upper end of the front leg tube 4 is rotatably connected to the bottom of the connecting seat 82, the rear end of the armrest tube 2 is rotatably connected to the backrest tube 6, and the middle parts of the front leg tube 4 and the rear leg tube 5 are rotatably connected to the front and rear parts of the seat tube 3, respectively.
[0033] like Figure 4 and Figure 5 As shown, the locking assembly 84 includes a height-adjustable toothed buckle 841 and a rotatable rotating handle 842 mounted on the connecting seat 82. The rotating handle 842 is used to drive the toothed buckle 841 to rise and fall, and through the cooperation of the rotating handle 842, the first protruding tooth 843 of the toothed buckle 841 can be locked into the tooth groove of the rack 83, and the connecting seat 82 is restricted from moving on the handrail tube 2, so as to form a gearless adjustment or any gear adjustment.
[0034] An elastic reset component is provided between the armrest tube 2 and the connecting seat 82. Specifically, the elastic reset component is a gas spring 81. The gas spring 81 is fixedly connected to the connecting seat 82. The telescopic end of the gas spring 81 is fixedly connected to the front end of the armrest tube 2 away from the backrest tube 6. When in use, the elastic force of the gas spring 81 is applied to the armrest tube 2 and drives the backrest tube 6 to rebound when the locking assembly 84 is unlocked, so as to form a reset setting.
[0035] In this embodiment, as Figure 5 and Figure 6 As shown, the rotary handle 842 has a gear portion 845, which meshes with the second convex tooth portion 844 of the toothed buckle 841 to drive the toothed buckle 841 to rise and fall, thereby enabling the first convex tooth portion 843 of the toothed buckle 841 to switch between the engaged position and the position away from the tooth groove of the rack 83, so as to correspond to the locked state and the unlocked state of the locking assembly 84 respectively.
[0036] like Figure 1 As shown, more specifically, the upper end of the rear leg tube 5 is rotatably connected to the upper part of the front leg tube 4 via a duckbill connector, and the lower end of the backrest tube 6 is rotatably connected to the rear end of the seat tube 3 via a U-shaped connector. The armrest tube 2, seat tube 3, backrest tube 6, front leg tube 4, rear leg tube 5, and the adjustable mechanism 8 together constitute the folding structure of the beach chair, thus ensuring that the beach chair can be folded into the shape shown. Figure 3 The folded state shown, or unfolded as shown Figure 1 The seat status shown or as Figure 2 The recliner is shown in the picture.
[0037] like Figure 4 and Figure 6 As shown, the gear portion 845 of the rotary handle 842 is rotatably mounted within the connecting seat 82 via a rotating shaft, and as... Figure 5 The toothed buckle 841 shown has a mounting groove 846 for accommodating the movement of the gear part 845.
[0038] Furthermore, the rack 83 has multiple continuously distributed toothed grooves, each toothed groove corresponding to an adjustment position and each backrest angle. Therefore, the gearless adjustment mechanism 8 in this embodiment has any position adjustment function and forms a corresponding backrest angle.
[0039] When the rotating handle 842 is turned, its gear part 845 drives the toothed buckle 841 to rise and fall, so that the first protruding tooth part 843 of the toothed buckle 841 switches between the position of engaging and moving away from the tooth groove of the rack 83, that is, the connecting seat 82 and the armrest tube 2 switch between the locked state and the unlocked state. When the included angle between the backrest tube 6 and the seat tube 3 is adjusted to the required unfolding angle (i.e., corresponding to any position), it is locked by the locking assembly 84 to ensure that a stable and safe support structure is formed.
[0040] When the latch assembly 84 is in the unlocked state and the backrest tube 6 rotates and unfolds to a certain angle, the gas spring 81 and the armrest tube 2 interact, and the backrest angle continues to increase. The gas spring 81 then generates a compressive force, which indirectly acts on the backrest tube 6 through the armrest tube 2. This not only provides support but also allows the gas spring 81 to return the backrest tube 6 to its original position when the user stands up, thus achieving self-return. Figure 1 The seat status is shown.
[0041] In summary, the backrest angle can be adjusted to any position or without any position via the stepless adjustment mechanism 8. Furthermore, when the locking assembly 84 is unlocked, the gas spring 81 drives the backrest tube 6 to rebound and reset, allowing the backrest tube 6 to automatically return to its original position. Figure 1 The seat position shown is simple in structure and easy to operate in this embodiment.
[0042] Further preferred, such as Figure 1 As shown, a hole offset sleeve 9 is provided between the front leg tube 4 and the seat tube 3. The hole offset sleeve 9 is fixedly sleeved on the seat tube 3. The front leg tube 4 is hinged to the lower end of the hole offset sleeve 9 away from the seat tube 3. With the cooperation of the hole offset sleeve 9, the seat tube 3 is nearly parallel to the front leg tube 4 and the rear leg tube 5 respectively after the beach chair is folded up. This can reduce the overall size of the beach chair after folding up.
[0043] Example 2
[0044] like Figure 7 As shown, Embodiment 2 provides a beach chair. The structure of Embodiment 2 is generally the same as that of Embodiment 1, except that the elastic reset component of Embodiment 2 is a spring 81'. One end of the spring 81' is connected to the armrest tube 2, and the other end is connected to the connecting seat 82.
[0045] More specifically, the gearless adjustment mechanism 8' also includes a slider 11 that is slidably mounted on the handrail tube 2. The slider 11 is located between the spring 81' and the connecting seat 82. The end of the spring 81' away from the handrail tube 2 is connected to the slider 11, and the end of the slider 11 away from the spring 81' abuts against the connecting seat 82.
[0046] When the latch assembly 84 is in the unlocked state and the backrest tube rotates and unfolds to a certain angle, the spring 81' and the armrest tube 2 interact with each other, and the backrest angle continues to increase. The spring 81' then generates a compressive force, which indirectly acts on the backrest tube through the armrest tube 2. This not only provides support, but also allows the spring 81' to return to its original position when the user gets up, thus completing the self-rebound to the seat position.
[0047] In a further preferred embodiment, a mounting bracket 10 is fixedly fitted onto the outer wall of the handrail tube 2, the mounting bracket 10 surrounds the connecting seat 82, one end of the spring 81' is connected to the mounting bracket 10, and the other end is connected to the slider 11.
[0048] The mounting bracket 10 is provided with a foolproof protrusion 101 at the end away from the spring 81' to prevent the connector 82 from falling out, thereby limiting the distance the connector 82 moves outward and preventing the connector 82 and the slider 11 from falling out of the handrail tube 2.
[0049] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
