[0029] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0030] Reference Figures 1 to 9As shown, a director's chair provided in this embodiment includes a chair frame and a seat, and the seat is supported on the chair frame to meet the needs of use. The chair frame includes two support frames 10, a folding frame 30 connected between the two support frames 10, and two armrest frames 20 respectively mounted on the two support frames 10; the two support frames 10 are connected by the folding frame 30 to achieve foldable storage and unfolding. Specifically, in this embodiment, the structure of the folding frame 30 is consistent with that of the director's chair disclosed in CN217285205U, and will not be described in detail here. Of course, in other embodiments, the folding frame 30 can also adopt other structures that can be folded.

[0031] The armrest frame 20 is hinged on the support frame 10 so as to be able to flip in a lateral direction relative to the support frame 10; at the same time, a fixing component is also provided between the armrest frame 20 and the support frame 10, and the fixing component fixes or releases the armrest frame 20 and the support frame 10.

[0032] The director's chair can operate the armrest frame 20 independently, such as Figure 1 and Figure 3 The handrail frame 20 is shown in a vertical state, and is fixed by a fixing assembly (specifically, the locking assembly 40 and the handrail slot 52 described below); when the position of the handrail frame 20 needs to be changed (for example, the handrail frame 20 is not needed in the unfolded state or the handrail frame 20 is folded and stored), the handrail frame 20 is released from the vertical position, and then the handrail frame 20 can swing outward. The user can change the position of the handrail frame 20 according to actual needs; it has the characteristics of simple structure and easy operation.

[0033] Furthermore, in this embodiment, two support frames 10 are arranged at intervals on the left and right, and each support frame 10 is a four-frame structure, specifically including a front tube 11, a rear tube 12, a lower support tube 13 and an upper support tube 14; further, the front tube 11, the rear tube 12 and the lower support tube 14 are integrally connected U-shaped tubes; the upper support tube 13 is connected to the front tube 11 through a seat tube connector 15; the upper support tube 13 is connected to the rear tube 12 through a back tube connector 16. A foot pad 17 is provided at the bottom of the support frame 10 to better achieve stable support.

[0034] The front tubes 11 of the two support frames 10 are both fixed with cup holder fixing parts 61. Specifically, the cup holder fixing parts 61 are fixed to the front tubes 11 of the support frames 10 by riveting, and the cup holder fixing parts 61 are provided with cup holder slots extending vertically. The director's chair also includes a cup holder 62, and the cup holder 62 is detachably connected to the cup holder slot of the cup holder fixing parts 61. In this way, the cup holder 62 can be detachably assembled, and the disassembly and assembly operation is simple, and the cup holder 62 can be selectively assembled on one of the cup holder fixing parts 61. Of course, in other embodiments, the cup holder fixing part 61 can also be fixed to the front tube 11 of one side of the support frame 10; or the structure without the cup holder fixing part 61, etc.

[0035] The handrail frame 20 is a U-shaped frame, and the two ends of the handrail frame 20 are hinged to the front end and the rear end of the support frame 10 respectively.

[0036] Furthermore, the front end of the handrail frame 20 is hinged on the seat tube connector 15; specifically, the seat tube connector 15 has a first hinged tube segment 151, and the handrail frame 20 is equipped with a second hinged tube segment 21, which is coaxial with the first hinged tube segment 151 and rotatably assembled at the rear end of the first hinged tube segment 151, so as to realize the hinged setting. The fixing assembly circumferentially limits the first hinged tube segment 151 and the second hinged tube segment 21 to achieve the fixation of the handrail frame 20 and the support frame 10; and the fixing assembly releases the circumferential limit of the first hinged tube segment 151 and the second hinged tube segment 21 to release the fixation of the handrail frame 20 and the support frame 10. The specific implementation is as follows: the fixing assembly includes a locking assembly 40, the locking assembly 40 includes a pressing key 41, a shift slider 42 and an elastic reset member 43, the shift slider 42 can be slidably assembled in the second hinged tube segment 21 and forms a circumferential limit with the second hinged tube segment 21; specifically, the second hinged tube segment 21 is provided with a protruding limit rib 211, the shift slider 42 is provided with a limit groove 422, and the limit groove 422 is matched with the limit rib 211 to achieve circumferential limit assembly, so that the shift slider 42 can only slide forward and backward. The front end of the shift slider 42 is provided with a plug-in convex portion 421, and the first hinged tube segment 151 is provided with a plug-in interface 152; the elastic reset member 43 applies a forward elastic force to the shift slider 42. When the armrest frame 20 swings to a preset position relative to the support frame 10 (such as when the armrest frame 20 swings to a vertical position), the plug-in protrusion 421 is aligned with the plug-in port 152 of the first hinged tube segment 151 and is inserted into the plug-in port 152 through the action of the elastic reset member 43, thereby circumferentially limiting the first hinged tube segment 151 and the second hinged tube segment 21, and fixing the armrest frame 20. The push button 41 is arranged at the front end of the first hinged tube segment 151, and has an abutment column 411 extending backward to abut against the gear slider 42. The backward pressing of the push button 41 drives the gear slider 42 to overcome the elastic force of the elastic reset member 43 and move backward, so that the plug-in protrusion 421 is disengaged from the plug-in port 152, thereby releasing the circumferential limit of the first hinged tube segment 151 and the second hinged tube segment 21, that is, releasing the fixation of the armrest frame 20, so that the armrest frame 20 can swing normally to adjust the position.

[0037] The push button 41 is arranged at the front end of the first hinged tube section 151, which is more convenient for the user to operate. Furthermore, in order to prevent the push button 41 from falling out, in this embodiment, a hook 412 is arranged at the rear end of the abutment column 411 of the push button 41, and the hook 412 is limited on the first hinged tube section 151, thereby preventing the push button 41 from falling out forward.

[0038] The rear end of the handrail frame 20 is hinged to the side of the rear back tube connector 16. Specifically, the side of the rear back tube connector 16 is provided with a lateral hinge groove 163, and the rear end of the handrail frame 20 is hinged in the lateral hinge groove 163. When the handrail frame 20 swings from outside to inside to a vertical position, it is abutted and limited by the rear back tube connector 16.

[0039] The chair frame also includes two back tubes 50, which are respectively hinged at the rear ends of the two support frames 10 and can be swung forward for storage, that is, when being stored, the back tubes 50 can be swung forward to achieve folding and storage. Specifically, the back tube 50 is hinged on the back tube connector 16, and specifically, the back tube connector 16 has a forward hinge groove 161 facing forward, and the back tube 50 is hinged in the forward hinge groove 161. The back tube connector 16 has a supporting portion 162 located at the rear of the back tube 50, and the supporting portion 162 is the rear side groove wall of the forward hinge groove 161; when the back tube 50 swings backward to a vertical position, it is fixed by the rear supporting portion 162.

[0040] The back tube 50 is equipped with an armrest connector 51, and the armrest connector 51 has an armrest slot 52. The fixing assembly also includes the armrest slot 52. When the back tube 50 is unfolded to a vertical state, the armrest slot 52 of the armrest connector 51 corresponds to the armrest frame 20, so that the armrest frame 20 can be inserted into the armrest slot 52 to achieve fixation when it swings to a vertical position. In this way, the front and rear ends of the armrest frame 52 can be fixed in a vertical state, and the support stability is better. When the fixation needs to be released, the push button 41 is pressed to release the fixation of the armrest frame 20 by the locking assembly. After that, an external force is applied to the armrest frame 20 to disengage it from the armrest slot 52.

[0041] The above embodiment discloses a preferred solution for fixing or releasing the handrail frame 20 and the support frame 10 by the fixing assembly, that is, the handrail frame 20 is fixed by the fixing assembly only when it is in a vertical state. Of course, other embodiments are not limited to this. For example, the first hinged tube section 151 is provided with multiple groups of notches 152, so that the handrail frame 20 can be fixed by the locking assembly 40 when it swings to multiple predetermined positions (such as a vertical position, multiple inclined positions, and a horizontal position); or the structure of the handrail slot 52 can be omitted. Or the fixing assembly is fixed in other ways; for example, a first connecting hole is provided on the first hinged tube section 151, and multiple second connecting holes are provided on the second hinged tube section 21. When one of the second connecting holes corresponds to the first connecting hole during the swinging process of the handrail frame 20, the handrail frame 20 and the support frame 10 are fixed by plugging and connecting through a latch member, so as to achieve the fixing of the handrail frame 20 and the support frame 10, and so on.

[0042] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
