Description

Technical Field

[0001] The present invention relates to the technical field of seats and related supporting equipment, and in particular to a wearable seat. Background Art

[0002] Wearable chairs were designed to address health issues associated with long hours of standing work, such as increased blood vessel pressure, reduced blood flow, and muscle tension. They are designed to provide a way for workers to quickly and easily sit down when needed, reducing the strain on their legs and back.

[0003] Although the wearable seats currently on the market can meet the needs of sitting down quickly and conveniently, when the user sits down, the existing wearable seats can only allow the user's feet to move in a small range when sitting because the distance between the foot fixing straps and the bottom of the seat is short, resulting in low mobility of the feet. In addition, when the user sits down, the seat cushion is located at the root of the thigh, and the seat cushion does not have enough supporting force for the user's body position and cannot provide a comfortable support effect. Therefore, based on the above problems, the present invention provides a wearable seat to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a wearable chair by arranging a lifting component and an extension component. The lifting component and the extension component are respectively arranged at the bottom and the top of the support frame. The lifting component can not only realize the free adjustment of the fixed distance of the feet and improve the mobility of the user's feet, but also can automatically reset when the user stands up, thereby realizing seamless switching between standing and sitting, thereby providing services for the user more conveniently; the extension component can not only extend one end of the seat cushion and change the support angle, but also can generate linkage with the lifting component, and use the movement of the lifting component to drive the adjustment of the extension component. Through the above arrangement, the problems of low mobility of the feet and low comfort of the seat cushion when the user sits down in the existing wearable chair can be solved.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A wearable chair comprises a support frame, a lifting assembly is fixedly mounted on the bottom of the support frame, the lifting assembly is used to improve the comfort of the user, and the lifting assembly is connected to the support frame; an extension assembly is used to improve the comfort of sitting posture, and the extension assembly is connected to the support frame.

[0007] Optionally, the lifting assembly includes a telescopic rod slidably connected to the bottom of the support frame, the bottom of the telescopic rod is slidably connected to a base, a spring sheet is sleeved on the top outer contour of the base, an adjustment rope is fixedly connected to the top center of the base, one side of the telescopic rod is rotatably connected to a connecting rod, a telescopic rope is provided inside the connecting rod, and the top of the telescopic rod is fixedly connected to the adjustment rope.

[0008] Optionally, a guide block is fixedly connected to the connection point between the telescopic rod and the connecting rod, and a guide hole matching the size of the telescopic rope is opened inside the guide block.

[0009] Optionally, a rope collecting box is fixedly connected to a position near the top of the retractable rope, and a clamping block is fixedly connected to a position near the bottom of the retractable rope, and the clamping block has a structure that is wide at the top and narrow at the bottom.

[0010] Optionally, a side of the guide block close to the adjusting rope is fixedly connected to a limiting block, the limiting block is an arc-shaped curved surface structure, and a position of the limiting block close to the adjusting rope is provided with an inverted curling edge.

[0011] Optionally, the free end of the retractable rope is fixedly connected to a shoe strap fixing point, the shoe strap fixing point is externally connected to the shoe strap, and the outer contour size of the shoe strap fixing point is larger than the inner contour size of the connecting rod.

[0012] Optionally, the extension component includes a seat cushion, an arc-shaped bracket is symmetrically installed on one side of the top of the seat cushion, an extension pad is slidably connected between the arc-shaped brackets, and the bottom center of the extension pad is fixedly connected to the top of the adjustment rope.

[0013] Optionally, lightweight grooves are evenly provided on the extension pad, and flanges with a C-shaped structure are provided on both sides of the extension pad, and weakened grooves are provided on the flanges.

[0014] Optionally, a waist belt fixing point is provided at the top of the seat cushion, and the waist belt fixing point is used to connect the waist belt strap externally. Thigh belt fixing points are provided on both sides of the bottom of the seat cushion, and the thigh belt fixing points are used to connect the thigh strap externally.

[0015] Optionally, a mounting hole larger than the outer contour size of the adjustment rope is opened through the interior of the support frame, and the adjustment rope passes through the mounting hole.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting a lifting component and an extension component, the lifting component and the extension component are respectively arranged at the bottom and the top of the support frame. The lifting component can not only realize the free adjustment of the fixed distance of the feet to improve the mobility of the user's feet, but also can automatically reset when the user stands up, to achieve seamless switching between standing and sitting, so as to provide services for the user more conveniently; the extension component can not only extend one end of the seat cushion and change the support angle, but also can be linked with the lifting component, and the movement of the lifting component is used to drive the adjustment of the extension component. Compared with a fixed seat cushion, such a setting cooperates with the seat cushion during the extension process to form an arc-shaped wrapping support, which is more in line with the user's body position in a sitting state, thereby improving the user's comfort.

[0018] By providing a base, an adjusting rope and a spring sheet, the overall contour of the base is an inverted T shape, which is convenient for lifting and lowering while playing a limiting role. A spring sheet is provided on the top outer contour of the base. The spring sheet is a gradually deformed curved elastic structure that is narrow at the top and wide at the bottom. When the base moves upward under the pressure of the user's gravity, the adjusting rope also moves upward synchronously. The spring sheet is squeezed and compressed between the base and the telescopic rod. When the user stands up, the pressure on the base is relieved. At this time, the spring sheet rebounds using its own elastic force, driving the base and the adjusting rope to return to their original state. Such a structural setting utilizes the user's own weight and the cooperation of the spring sheet to achieve the rising and automatic resetting of the base and the adjusting rope. The operation is convenient and simple, which improves the convenience and flexibility of user use.

[0019] The clamping block, the guide block and the limit block are arranged, when the user is in a standing state, the bottom of the clamping block enters the guide hole of the guide block, clamps and limits the telescopic rope, so that the telescopic rope cannot be freely extended and retracted. When the user is in a sitting state, the adjusting rope moves upward and drives the telescopic rope upward synchronously. At this time, the clamping block is also synchronously driven to move upward, and contacts the clamping limit of the telescopic rope, so that the telescopic rope can be freely extended and retracted under the action of the rope collection box, thereby ensuring the mobility and flexibility of the user's feet. The telescopic rope is built into the guide hole and slides and retracts, which not only greatly reduces the friction and prolongs the service life of the telescopic rope, but also cooperates with the clamping block to lock the telescopic rope. When the user switches from a sitting position to a standing position, the role of the limit block is to assist the clamping block to slide smoothly into the guide hole, so as to clamp and limit the telescopic rope. The arc-shaped smooth curved surface of the limit block is set, so that the clamping block can only slide along the outer contour of the limit block, and the inner rolled flange setting of the limit block reduces the friction with the adjusting rope and avoids damage to the adjusting rope.

[0020] By providing an arc-shaped bracket and an extension pad, the arcs of the arc-shaped bracket and the extension pad are matched, and C-shaped arc profiles are provided on both sides of the extension pad to match the outer profile of the arc-shaped bracket, so that the extension pad can only slide along the arc-shaped gap between the seat cushion and the arc-shaped bracket, which is convenient for the extension pad to match with the arc-shaped bracket. When the adjustment rope moves upward, the extension pad is prompted to slide upward, thereby matching with the seat cushion to form a support effect that fits the user's sitting posture, thereby improving the user's comfort.

[0021] By setting lightweight grooves and weakened grooves, evenly distributed lightweight grooves and weakened grooves are opened on the extension pad. The opening of the lightweight grooves can reduce the weight of the structure and improve the lightness and practicality of the overall structure. The setting of the weakened grooves ensures the supporting strength while facilitating the bending of the extension pad. In addition, the arc bracket, seat cushion and support frame are an integrated manufacturing structure, which saves process while providing strong support. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] like Figures 1 to 8 As shown, an embodiment of the present invention provides a wearable chair, including a support frame 2, a lifting component is fixedly installed on the bottom of the support frame 2, the lifting component is used to improve the comfort of the user, and the lifting component is connected to the support frame 2; an extension component, the extension component is used to improve the comfort of the sitting posture, and the extension component is connected to the support frame 2. The wearable chair provided by the present application is suitable for improving the sitting comfort of the user in the process of the seat and its related supporting facilities, and the structural coordination between the lifting component and the extension component is utilized to achieve the coordination between the two components, and the user's own weight and the coordination between the various structures are utilized to achieve the rise and automatic resetting of the base 5 and the adjustment rope 3, which is convenient and simple to operate, thereby improving the convenience and flexibility of user use.

[0040] By setting a lifting component and an extension component, the lifting component and the extension component are respectively arranged at the bottom and the top of the support frame 2. The lifting component can not only realize the free adjustment of the fixed distance of the feet and improve the mobility of the user's feet, but also can automatically reset when the user stands up, realizing seamless switching between standing and sitting, thereby providing services for the user more conveniently; the extension component can not only extend one end of the seat cushion 1 and change the support angle, but also can be linked with the lifting component, and the movement of the lifting component is used to drive the adjustment of the extension component. Compared with the fixed seat cushion 1, such a setting cooperates with the seat cushion 1 during the extension process to form an arc-shaped wrapping support, which is more in line with the user's body position in a sitting state, thereby improving the user's comfort.

[0041] like Figures 1 to 6As shown, the lifting assembly includes a telescopic rod 4 slidably connected to the bottom of the support frame 2, the bottom of the telescopic rod 4 is slidably connected to a base 5, a spring sheet 501 is sleeved on the top outer contour of the base 5, an adjusting rope 3 is fixedly connected to the top center of the base 5, one side of the telescopic rod 4 is rotatably connected to a connecting rod 6, a telescopic rope 601 is arranged inside the connecting rod 6, the top of the telescopic rod is fixedly connected to the adjusting rope 3, a mounting hole larger than the outer contour size of the adjusting rope 3 is opened inside the support frame 2, the adjusting rope 3 runs through the mounting hole, the outer contour size of the telescopic rod 4 coincides with the inner wall size of the bottom of the support frame 2, the size of the inner wall of the telescopic rod 4 coincides with the outer contour size of the top of the base 5, a plurality of gears are arranged at the bottom of the support frame 2 to adjust the overall height of the support frame 2 to adapt to users of different heights, the height adjustment structure of the support frame 2 and its working principle are disclosed as prior art and therefore will not be described in detail, the upper and lower parts rotatably connected between the support frames 2 are convenient for users to switch between standing and sitting positions, the angle adjustment between the support frames 2 and its working principle are disclosed as prior art and therefore will not be described in detail.

[0042] By providing the base 5, the adjusting rope 3 and the spring piece 501, the overall contour of the base 5 is an inverted T-shape, which is convenient for lifting and lowering and plays a limiting role at the same time, and the top outer contour of the base 5 is provided with a spring piece 501, and the spring piece 501 is a gradually deformed curved elastic structure that is narrow at the top and wide at the bottom. When the base 5 moves upward under the pressure of the user's gravity, the adjusting rope 3 also moves upward synchronously, and the spring piece 501 is squeezed and compressed between the base 5 and the telescopic rod 4. When the user stands up, the pressure on the base 5 is released. At this time, the spring piece 501 rebounds by its own elastic force, driving the base 5 and the adjusting rope 3 to return to their original state. Such a structural setting utilizes the user's own weight and the cooperation of the spring piece 501 to realize the rising and automatic resetting of the base 5 and the adjusting rope 3. The operation is convenient and simple, which improves the convenience and flexibility of user use.

[0043] In this embodiment, if Figures 3 to 6As shown, the connection between the telescopic rod 4 and the connecting rod 6 is fixedly connected with a guide block 604, and a guide hole adapted to the size of the telescopic rope 601 is opened inside the guide block 604. The position of the telescopic rope 601 near the top is fixedly connected with a rope collection box 602, and the bottom of the rope collection box 602 is fixedly connected with a clamping block 603 near the telescopic line. The clamping block 603 is a structure with a wide top and a narrow bottom. The side of the guide block 604 near the adjusting rope 3 is fixedly connected with a limiting block 605, and the limiting block 605 is an arc-shaped curved surface structure. The limiting block 605 is provided with an inverted curling edge near the adjusting rope 3. The telescopic rope 601 The free end is fixedly connected to a shoe strap fixing point 606, and the shoe strap fixing point 606 is externally connected to the shoe strap. The outer contour size of the shoe strap fixing point 606 is larger than the inner contour size of the connecting rod 6, and an arc-shaped guide hole with an aperture matching the telescopic rope 601 is opened inside the guide block 604 to ensure that the telescopic rope 601 can slide along the path of the guide hole and reduce the friction of the telescopic rope 601. An automatic rope-collecting wheel is installed in the rope-collecting box 602 through a rotating shaft and a torsion spring. The inner end of the telescopic rope 601 is fixed on the automatic rope-collecting wheel, and the outer end extends out from the rope outlet on the side wall of the rope-collecting box 602. A circle of limiting bosses are evenly arranged on the outer wall of the automatic rope collecting wheel, and a limiting hole connecting the inside and outside of the rope collecting box 602 is opened on the outer shell. A limiting bolt is installed in the limiting hole and cooperates with the limiting boss to limit the rotation of the automatic rope collecting wheel. The internal structure and working principle of the rope collecting box 602 are disclosed as prior art and therefore will not be described in detail. The outer contour size of the shoe strap fixing point 606 is larger than the inner contour size of the connecting rod 6, which is convenient for clamping with the inner wall of the connecting rod 6 to achieve the fixation of the shoe strap fixing point 606 and the connecting rod 6 to ensure that it does not affect the user's sports experience when standing and walking.

[0044] By setting the clamping block 603, the guide block 604 and the limit block 605, when the user is standing, the bottom of the clamping block 603 enters the guide hole of the guide block 604, clamping and limiting the telescopic rope 601, so that the telescopic rope 601 cannot be freely extended and retracted. When the user sits down, the adjustment rope 3 moves upward and drives the telescopic rope 601 upward synchronously. At this time, the clamping block 603 is also driven upward synchronously to contact the clamping limit of the telescopic rope 601, so that the telescopic rope 601 can be freely extended and retracted under the action of the rope collection box 602, thereby ensuring the mobility and flexibility of the user's feet. The telescopic rope 601 The built-in sliding and telescopic structure in the guide hole not only greatly reduces the friction and prolongs the service life of the telescopic rope 601, but also cooperates with the card block 603 to lock the telescopic rope 601. When the user switches from a sitting position to a standing position, the function of the limit block 605 is to assist the card block 603 to slide smoothly into the guide hole to clamp and limit the telescopic rope 601. The arc-shaped smooth surface setting of the limit block 605 makes the card block 603 only slide along the outer contour of the limit block 605, and the inner rolled edge setting of the limit block 605 reduces the friction with the adjustment rope 3 and avoids damage to the adjustment rope 3.

[0045] like Figures 1 to 3 , Figure 5 and Figures 7 and 8 As shown, the extension component includes a seat cushion 1, an arc-shaped bracket 7 is symmetrically installed on one side of the top of the seat cushion 1, an extension pad 8 is slidably connected between the arc-shaped brackets 7, the bottom center of the extension pad 8 is fixedly connected to the top of the adjustment rope 3, and lightweight grooves 801 are evenly opened on the extension pad 8. Both sides of the extension pad 8 are provided with C-shaped flanges, and weakened grooves 802 are opened on the flanges. A waist belt fixing point 101 is opened on the top of the seat cushion 1, and the waist belt fixing point 101 is used for external waist belt straps. Thigh strap fixing points 102 are opened on both sides of the bottom of the seat cushion 1, and the thigh strap fixing points 102 are used for external thigh straps. Both sides of the extension pad 8 are provided with C-shaped flanges that match the outer contour size of the arc-shaped bracket 7, which facilitates sliding while also ensuring the connectivity between the extension pad 8 and the arc-shaped bracket 7, ensuring the stability and firmness of the overall structural support. The main function of the waist belt strap and the thigh strap is to fix the seat to the wearer's body and ensure the stability of the seat during use. These straps can be adjusted according to the comfort of the wearer, and the tightness can be adjusted through Velcro to accommodate wearers of different body shapes to ensure that the seat fits the body and provides optimal support and comfort. When the wearer needs to switch from standing to sitting, the thigh straps will help support the weight of the thighs, and the waist belt straps will help stabilize the entire seat, making the switching process quick and requiring no manual operation. They not only ensure the stability and safety of the seat, but also improve the wearer's comfort and work efficiency. The Velcro structure of the waist belt straps and thigh straps and their working principles are disclosed as prior art and therefore will not be elaborated on.

[0046] By setting the arc bracket 7 and the extension pad 8, the arcs of the arc bracket 7 and the extension pad 8 match each other, and the two sides of the extension pad 8 are provided with C-shaped arc profiles that match the outer profile of the arc bracket 7, so that the extension pad 8 can only slide along the arc gap between the seat cushion 1 and the arc bracket 7, which is convenient for the extension pad 8 to cooperate with the arc bracket 7. When the adjustment rope 3 moves upward, the extension pad 8 is prompted to slide upward, thereby cooperating with the seat cushion 1 to form a support effect that fits the user's sitting posture, thereby improving the user's comfort. By setting the lightweight groove 801 and the weakened groove 802, the extension pad 8 can be extended to the seat cushion 1. The pad 8 is provided with evenly distributed lightweight grooves 801 and weakened grooves 802. The lightweight grooves 801 can reduce the weight of the structure and improve the lightness and practicality of the overall structure. The weakened grooves 802 ensure the support strength while facilitating the bending of the extended pad 8. In addition, the arc bracket 7, the seat cushion 1 and the support frame 2 are an integrated manufacturing structure, which saves process and can provide strong support force. The integrated manufacturing structure makes the processing technology of the three simpler during the production process, easier to produce, and reduces the manufacturer's capital investment.

[0047] The workflow of the technical solution provided by the present invention is as follows:

[0048] When the user sits down, the base 5 moves upward due to the pressure of the user's gravity, and the adjusting rope 3 also moves upward synchronously. The spring piece 501 is squeezed and compressed between the base 5 and the telescopic rod 4. The adjusting rope 3 moves upward and drives the telescopic rope 601 upward synchronously. At this time, the block 603 is also driven upward synchronously, contacting the clamping limit of the telescopic rope 601, so that the telescopic rope 601 can be freely extended and retracted under the action of the rope collection box 602, ensuring the mobility and flexibility of the user's feet. The telescopic rope 601 is built in the guide hole to slide and retract without It not only greatly reduces the friction force and prolongs the service life of the telescopic rope 601, but also cooperates with the card block 603 to lock the telescopic rope 601. When the user switches from a sitting position to a standing position, the function of the limit block 605 is to assist the card block 603 to slide smoothly into the guide hole, so as to clamp and limit the telescopic rope 601. The arc-shaped smooth surface setting of the limit block 605 makes the card block 603 only slide along the outer contour of the limit block 605, and the inner rolled edge setting of the limit block 605 reduces the friction with the adjustment rope 3 and avoids damage to the adjustment rope 3.

[0049] When the user stands up, the pressure on the base 5 is released. At this time, the spring piece 501 rebounds by its own elastic force, driving the base 5 and the adjusting rope 3 to return to their original state. Such a structural setting utilizes the user's own weight and the cooperation of the spring piece 501 to realize the rising and automatic reset of the base 5 and the adjusting rope 3. The operation is convenient and simple, which improves the convenience and flexibility of the user. At this time, the bottom of the clamping block 603 is located in the guide hole of the guide block 604, and the telescopic rope 601 is clamped and limited, so that the telescopic rope 601 cannot be freely extended and retracted. By setting a lifting component and an extension component, the lifting component and the extension component are respectively arranged at the bottom and the top of the support frame 2. The lowering component can not only realize the free adjustment of the fixed distance of the feet and improve the mobility of the user's feet, but also can automatically reset when the user stands up, realizing seamless switching between standing and sitting, thereby providing services for users more conveniently; the extension component can not only extend one end of the seat cushion 1 and change the support angle, but also can interact with the lifting component, using the movement of the lifting component to drive the adjustment of the extension component. Compared with the fixed seat cushion 1, such a setting cooperates with the seat cushion 1 during the extension process to form an arc-shaped wrapping support, which is more in line with the user's body position in a sitting state, thereby improving the user's comfort.
