Description

Technical Field

[0001] This utility model relates to the technical field of portable folding chairs, and in particular to a portable folding chair. Background Technology

[0002] In assembly processes, operators often need to stand or maintain a semi-squatting posture for extended periods to complete tasks. This not only severely impacts the efficiency and quality of the assembly process but also leads to numerous health problems for workers, easily inducing occupational musculoskeletal disorders (WMSDs). Similarly, in hospital operating rooms, surgeons and first assistants focus on the operation, while second assistants, with less workload, require a portable chair for rest. In recent years, with the rapid development of robotics technology, an increasing number of assistive exoskeleton robots have emerged. To address these issues, wearable chair-type exoskeletons have been developed, providing workers with prolonged static support while also being portable.

[0003] Among existing portable folding chairs, such as the wearable exoskeleton chair with an added auxiliary support device disclosed in the invention patent application number 202111282708.7, the height of the wearer's sitting posture when using the exoskeleton can be infinitely adjusted by manually controlling the length of the controllable gas spring.

[0004] However, when using a portable folding chair, the device is unstable in lateral support, which can cause the user to sway and tip over. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a portable folding chair that improves the stability of the device during use by setting up a support mechanism and a leg mechanism, thereby extending the legs.

The connecting mechanism is installed on the two sets of fitting mechanisms, each set of fitting mechanisms is equipped with a set of supporting mechanisms, each set of fitting mechanisms is equipped with a set of leg mechanisms, and the fixing mechanism is installed on the two sets of fitting mechanisms.

[0007] The fitting mechanism fits the user, the connecting mechanism connects the two fitting mechanisms, the fixing mechanism fixes the user, the supporting mechanism supports the user, and the foot mechanism stabilizes the user. The fitting mechanism fits the user, the connecting mechanism connects the two fitting mechanisms, the fixing mechanism locks the user, the supporting mechanism supports the fitting mechanism, and the foot mechanism stabilizes the device. Thus, the extended feet improve the stability of the portable folding chair during use.

[0008] Preferably, the fitting mechanism includes a thigh support, a calf support, and a buttock support, with the calf support rotatably connected to the thigh support and the buttock support mounted on the thigh support; the thigh support and calf support fit the user's thighs and calves, while the buttock support supports the user's buttocks.

[0009] Preferably, the connecting mechanism includes a ball head sleeve and a ball head. The ball head sleeve is installed on a set of thigh supports, and the ball head is installed on a set of thigh supports. The ball head sleeve is also installed inside the ball head sleeve. The ball head sleeve and the ball head allow for more diverse movement of the two sets of thigh supports.

[0010] Preferably, the support mechanism includes a support rod, a second spring, a locking box, and a first spring. The support rod is rotatably mounted on the thigh support and is connected to the thigh support via the second spring. The locking box is slidably mounted on the calf support and is rotatably connected to the support rod. The locking box is connected to the calf support via the first spring. The support rod is pressed down by bending the thigh support, causing the locking box to slide. The second spring and the first spring provide reset support.

[0011] Preferably, the support mechanism includes a sleeve, a support foot, a third spring, a third connecting rod, and four sets of extension rods. The sleeve is rotatably mounted on the locking box. The support foot is slidably mounted inside the sleeve via the third spring.

Every two sets of extension rods are rotatably connected, and both sets of extension rods are rotatably connected to the sleeve and the two sets of extension rods are rotatably connected to the support foot. By pressing down the sleeve with the locking box, the support foot retracts and supports the third connecting rod, thereby supporting the extension rods on both sides for stability.

[0012] Preferably, the fixing mechanism includes eight sets of Velcro straps and a fixing belt. Each set of thigh supports has two sets of Velcro straps, each set of calf supports has two sets of Velcro straps, and the fixing belt is installed on the two sets of thigh supports. The Velcro straps fix the user's thighs and calves, and the fixing belt fixes the user's waist.
