Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of seats, in particular to a multi-directional adjustment mechanism for a footrest. Background Art
[0002] Correcting the sitting posture is an important way to maintain the health of children's spine. Existing children's chairs usually have a footrest on the chair legs or support frames. When children sit on the children's chairs, their feet can step on the footrest, thereby providing stable support for children and helping them correct their sitting posture. However, children grow rapidly, and their legs also grow longer with their body size. If the height of the footrest cannot be adjusted, the height of the footrest will not match the position of the child's feet after growth, thereby failing to provide effective support for children and failing to help them correct their sitting posture.
[0003] The existing patent provides a child seat with an adjustable height footrest (application number: CN201921287111.X). A longitudinal adjustment piece is provided at the bottom of the seat, and a connecting piece is connected to the rear side of the footrest. A plurality of gear limit holes are provided on the longitudinal adjustment piece. The longitudinal adjustment piece and the connecting piece are slidably matched, and the gear is fixed by passing a locking knob through the gear limit holes on the connecting piece and the longitudinal adjustment piece, thereby achieving adjustable vertical height of the footrest relative to the seat.
[0004] However, the above solution has the following problems: during the development of children's legs, the thighs and calves grow synchronously, which makes the distance between the feet and the ground become shorter and the horizontal distance between the feet and the seat become longer when the children sit on the seat. If the footrest can only be adjusted in vertical height, the feet may be located in front of the footrest after the children's legs develop, and the calves need to be bent inwards to support the feet, resulting in an improper sitting posture for the children, which affects the children's spinal health. Therefore, only adjusting the vertical height of the footrest cannot meet the needs of children's body growth. Summary of the invention
[0005] In view of the above-mentioned defects or shortcomings in the prior art, it is desired to provide a multi-directional adjustment mechanism for the footrest, by which the horizontal portion of the support rod can be slid forward and backward relative to the connecting portion, and the footrest body can slide up and down relative to the supporting portion, so that the horizontal position and vertical position of the footrest body relative to the seat can be adjusted, and the adjustment freedom is relatively high, ensuring that the adjusted position of the footrest body can support and assist the user to maintain a correct sitting posture.
[0006] The effect of the utility model is achieved in this way:
[0007] The present application provides a multi-directional adjustment mechanism for a pedal, comprising:
[0008] The mounting member is a tubular member, including a mounting opening provided through the center, the mounting opening is configured to be sleeved with a gas pressure rod of the seat, and a connecting portion protrudes from the front end of the mounting member;
[0009] The pedal body is configured to support the user's feet, and a sliding groove is provided on the pedal body in a vertical direction;
[0010] The support rod includes a horizontal portion arranged transversely, and the front end of the horizontal portion is bent downward to form a support portion. The support portion slides with the pedal body through a sliding groove, so that the pedal body can slide up and down relative to the support portion; the horizontal portion can slide forward and backward relative to the connecting portion, and drive the pedal body connected to the support rod to slide forward and backward, and a positioning assembly is arranged between the horizontal portion and the connecting portion, and the positioning assembly is configured to fix the horizontal portion to the connecting portion.
[0011] Furthermore, the connecting part is a tubular structure, and the hollow portion of the connecting part is a connecting groove, which extends horizontally in the front-to-back direction. The horizontal part is plug-fitted into the connecting groove and the connecting part, which not only makes the connection strength between the horizontal part and the connecting part higher, but also makes the sliding operation of the horizontal part in the connecting groove smoother.
[0012] Furthermore, the positioning assembly includes a first knob screw, which passes through and is screwed to the connecting portion, and is configured to lock or loosen the horizontal portion. The horizontal portion can be locked or loosened by turning the first knob screw, making the positioning and adjustment operation of the horizontal portion relatively simple.
[0013] Furthermore, the mounting part is a split structure, and the mounting part includes two front and rear semicircular tubes spliced front and back, and the front and rear semicircular tubes are rotatably connected by a rotating shaft, and the ends of the front and rear semicircular tubes that are away from the rotating shaft and can be spliced with each other are respectively the front splicing end and the rear splicing end; the mounting part is also provided with a second knob screw, which passes through and is screwed to the front splicing end and the rear splicing end, and the second knob screw is configured to adjust the closure between the front splicing end and the rear splicing end. The mounting part can be used for various types of seats by opening or closing the front and rear semicircular tubes, and the loading and unloading operation is convenient and practical; the front and rear semicircular tubes are opened or closed by the second knob screw, so that the opening and closing adjustment operation of the mounting part is more convenient; and the second knob screw will not contact the gas pressure rod of the seat when it is screwed, so as to avoid wearing the side wall of the gas pressure rod.
[0014] Furthermore, a positioning assembly is provided between the front splicing end and the rear splicing end, and the positioning assembly includes a positioning protrusion and a positioning groove that are engaged with each other, the positioning protrusion protrudes from one of the front splicing end and the rear splicing end, and the positioning groove protrudes from the other of the front splicing end and the rear splicing end. Positioning is performed by engaging the positioning protrusion and the positioning groove, so that the closed positioning operation of the mounting piece is more stable and convenient.
[0015] Furthermore, the positioning protrusion protrudes from the front splicing end, the positioning groove is opened at the rear splicing end, and the screw portion of the second knob screw passes through and is screwed to the positioning protrusion and the positioning groove. After the positioning protrusion and the positioning groove are engaged, the threaded holes thereon can also be aligned, so that it is convenient to screw in the second knob screw and fix the front splicing end and the rear splicing end in series.
[0016] Furthermore, the mounting piece is an integrated structure, and a third knob screw is also provided on the mounting piece, and the third knob screw passes through and is screwed to the mounting piece, and the third knob screw is configured to lock or loosen the gas pressure rod of the seat. This makes the overall strength of the mounting piece higher, and the gas pressure rod of the seat is locked or loosened by screwing the third knob screw on the side wall of the mounting piece, making the mounting piece easier to install and remove.
[0017] Furthermore, an avoidance groove is provided on the inner wall of the installation opening, and a transition plate is connected to the side of the avoidance groove close to the installation opening. The transition plate has a certain elastic deformation capacity, and the screw portion of the third knob screw passes through the avoidance groove and pushes the transition plate. The transition plate is configured to increase the contact area between the screw portion of the third knob screw and the seat gas pressure rod. By providing the transition plate, the contact area between the screw portion of the third knob screw and the seat gas pressure rod is increased, thereby avoiding the gas pressure rod from being worn due to the third knob screw directly abutting against the gas pressure rod.
[0018] Furthermore, the support part is tilted downward and forward, so that when the pedal body slides up and down along the support part, the position of the pedal body in the horizontal direction also changes synchronously, so that the position change of the pedal body during adjustment is more in line with the change of the foot position of the child as he grows, which is more ergonomic.
[0019] Furthermore, a gear adjustment mechanism is provided between the support part and the pedal body, and the gear adjustment mechanism includes a gear switching member, a bayonet is provided on the gear switching member, and a plurality of slots for engaging with the bayonet are provided along the length direction of the support part; the gear switching member is rotatably connected to the pedal body, and a clearance hole connected to the sliding groove is provided through the side wall of the pedal body, and the bayonet passes through the clearance hole; when the pedal body slides up and down relative to the support part, the bayonet avoids the slot; when the pedal body is fixed to the support part, the bayonet passes through the clearance hole and engages with the slot in the sliding groove. This not only makes the gear adjustment operation simpler, but also makes the connection strength between the pedal body and the support part higher after the gear is fixed.
[0020] Furthermore, a mounting groove is provided at the rear end of the pedal body, and the gear switching member is installed in the mounting groove. The gear switching member includes a lower pushing portion and an upper reset portion. The middle portion of the gear switching member and the mounting groove are rotatably connected via a rotating shaft, so that the pushing portion and the reset portion can rotate synchronously around the rotating shaft. The bayonet is connected to the pushing portion, and the avoidance hole is provided in the mounting groove. An elastic member is provided between the mounting groove and the reset portion. The elastic member pushes the reset portion, so that the reset portion always has a tendency to rotate backward, thereby driving the pushing portion to have a tendency to rotate toward the mounting groove, so that the bayonet can always have a tendency to be inserted into the slot. By providing the elastic member, the bayonet always has a tendency to be inserted into the slot; and the user can press the reset portion to make the bayonet avoid the slot, so that the pedal body can slide freely on the support portion again.
[0021] Furthermore, a foot pad is connected to the bottom of the support part, a ball joint protrudes from the bottom end of the support part, a ball groove is provided at the upper end of the foot pad, and the ball joint is inserted into the ball groove, so that the foot pad can rotate in all directions relative to the support part. The foot pad not only provides support for the support rod, but also prevents the support part from contacting the ground and scratching the floor; moreover, the foot pad can automatically rotate to fit the ground at any height and inclination to improve stability.
[0022] The multi-directional adjustment mechanism of the footrest provided by the present application is arranged so that the horizontal part of the support rod can slide forward and backward relative to the connecting part, so that the footrest body connected to the support rod can be driven by the horizontal part to slide forward and backward, and the footrest body can slide up and down relative to the support part. Therefore, when the mounting piece is sleeved on the gas pressure rod of the seat, the horizontal position and vertical position of the footrest body relative to the seat can be adjusted, and the adjustment freedom is high, ensuring that the adjusted position of the footrest body can support and assist the user to maintain a correct sitting posture.

The support portion 320 is slidably matched with the pedal body 2 through the sliding groove 210, so that the pedal body 2 can slide up and down relative to the support portion 320; the horizontal portion 310 can slide forward and backward relative to the connecting portion 110, and drive the pedal body 2 connected to the support rod 3 to slide forward and backward, and a positioning assembly is arranged between the horizontal portion 310 and the connecting portion 110, and the positioning assembly is configured to fix the horizontal portion 310 to the connecting portion 110.
[0042] In this embodiment, the horizontal portion 310 of the support rod 3 can be slid forward and backward relative to the connecting portion 220, so that the pedal body 2 connected to the support rod 3 can be driven by the horizontal portion 310 to slide forward and backward, and the pedal body 2 can slide up and down relative to the support portion 320. Therefore, when the mounting member 1 is sleeved on the gas pressure rod of the seat, the horizontal position and vertical position of the pedal body 2 relative to the seat can be adjusted, and the degree of adjustment freedom is high, ensuring that the adjusted position of the pedal body 2 can support and assist the user to maintain a correct sitting posture.
[0043] In some embodiments of the present application, the connecting portion 110 is a tubular structure, the hollow portion of the connecting portion 110 is a connecting groove 111, the connecting groove 111 extends horizontally in the front-to-back direction, and the horizontal portion 310 is plug-fitted with the connecting portion 110 through the connecting groove 111.
[0044] In this embodiment, by setting the connecting part 110 as a tubular structure, the horizontal part 310 and the connecting part 110 are plugged together, which not only makes the connection strength between the horizontal part 310 and the connecting part 110 higher, but also makes the sliding operation of the horizontal part 310 in the connecting groove 111 smoother.
[0045] In other embodiments of the present application, the connecting portion 110 may also be a solid structure, and a guide groove extending in the front-to-back direction is provided on the side wall of the connecting portion 110, and the horizontal portion 310 slides together with the connecting portion 110 through the guide groove; or, a plurality of threaded holes are provided on the connecting portion 110 and the horizontal portion 310, and the horizontal portion 310 can move freely relative to the connecting portion 110.

[0047] In this embodiment, the horizontal portion 310 can be locked or loosened by turning the first knob screw 112 , so that the positioning and adjustment operation of the horizontal portion 310 is relatively simple.
[0048] In other embodiments of the present application, the positioning component can also be a pin and a shift slot. By opening a plurality of shift slots on the horizontal part 310, when the horizontal part 310 needs to be positioned, the pin is inserted from the through hole opened on the connecting part 110 and snapped into the shift slot, thereby achieving relative fixation between the horizontal part 310 and the connecting part 110.
[0049] In some embodiments of the present application, the mounting member 1 is a split structure, and the mounting member 1 includes a front semicircular tube 120 and a rear semicircular tube 130 that are spliced front and back, and the front semicircular tube 120 and the rear semicircular tube 130 are rotatably connected via a rotating shaft, and the ends of the front semicircular tube 120 and the rear semicircular tube 130 that are away from the rotating shaft and can be spliced with each other are respectively a front splicing end 121 and a rear splicing end 131; a second knob screw 132 is also provided on the mounting member 1, and the second knob screw 132 passes through and is screwed to the front splicing end 121 and the rear splicing end 131, and the second knob screw 132 is configured to adjust the closure between the front splicing end 121 and the rear splicing end 131.
[0050] In this embodiment, by setting the mounting member 1 as two semicircular tubes rotatably connected to each other, the mounting member 1 can be used for various types of seats by opening or closing the front semicircular tube 120 and the rear semicircular tube 130 for repeated loading and unloading, and the loading and unloading operation is convenient and practical; the front semicircular tube 120 and the rear semicircular tube 130 are opened or closed by the second knob screw 132 to adjust the opening or closing, so that the opening and closing adjustment operation of the mounting member 1 is relatively convenient; and the second knob screw 132 is screwed to the front splicing end 121 and the rear splicing end 131 of the side ends of the front semicircular tube 120 and the rear semicircular tube 130, so that the second knob screw 132 will not contact the pneumatic rod of the seat when being screwed, thereby preventing the second knob screw 132 from wearing the side wall of the pneumatic rod.
[0051] In some embodiments of the present application, a positioning assembly is arranged between the front splicing end 121 and the rear splicing end 131, and the positioning assembly includes a positioning protrusion 122 and a positioning groove 133 that are snap-fitted with each other, the positioning protrusion 122 protrudes from one of the front splicing end 121 and the rear splicing end 131, and the positioning groove 133 protrudes from the other of the front splicing end 121 and the rear splicing end 131.
[0052] In this embodiment, by providing a positioning assembly, it is convenient to position the front semicircular tube 120 and the rear semicircular tube 130 by snap-fitting the positioning protrusion 122 and the positioning groove 133 when closing, thereby making the closing and positioning operation of the mounting member 1 more stable and convenient.
[0053] In some embodiments of the present application, the positioning protrusion 122 protrudes from the front splicing end 121 , the positioning slot 133 is opened at the rear splicing end 131 , and the screw portion of the second knob screw 132 passes through and is screwed to the positioning protrusion 122 and the positioning slot 133 .
[0054] In this embodiment, after the positioning protrusion 122 and the positioning groove 133 are engaged, the threaded holes thereon can also be aligned, so that it is convenient for the second knob screw 132 to be screwed in and fix the front splicing end 121 and the rear splicing end 131 in series.
[0055] In some embodiments of the present application, the mounting member 1 is an integrated structure, and a third knob screw 140 is also provided on the mounting member 1. The third knob screw 140 passes through and is screwed to the mounting member 1. The third knob screw 140 is configured to lock or loosen the pneumatic rod of the seat.
[0056] In the embodiment itself, the mounting component 1 is set as an integrated structure so that the overall strength of the mounting component 1 is higher, and the pneumatic rod of the seat is locked or loosened by screwing the third knob screw 140 on the side wall of the mounting component 1, so as to achieve the positioning of the mounting component 1 on the pneumatic rod, making the loading and unloading operations of the mounting component 1 relatively simple.
[0057] In some embodiments of the present application, an avoidance groove 150 is opened on the inner wall of the installation port 101, and a transition plate 151 is connected to the side of the avoidance groove 150 close to the installation port 101. The transition plate 151 has a certain elastic deformation ability. The screw portion of the third knob screw 140 passes through the avoidance groove 150 and pushes the transition plate 151. The transition plate 151 is configured to increase the contact area between the screw portion of the third knob screw 140 and the seat gas pressure rod.
[0058] In this embodiment, the contact area between the screw portion of the third knob screw 140 and the seat pneumatic rod is increased by providing a transition plate 151, thereby increasing the friction between the mounting member 1 and the pneumatic rod, thereby avoiding wear of the pneumatic rod due to direct contact of the third knob screw 140 against the pneumatic rod.
[0059] In some embodiments of the present application, the support portion 320 is tilted toward the front and bottom, so that when the pedal body 2 slides up and down along the support portion 320, the position of the pedal body 2 in the horizontal direction also changes synchronously.
[0060] In this embodiment, as the child's legs grow, the position of his or her feet moves forward and downward relative to the seat; by tilting the support portion 320 toward the front and downward, when the pedal body 2 slides upward, the horizontal distance between the pedal body 2 and the seat becomes shorter; when the pedal body 2 slides downward, the horizontal distance between the pedal body 2 and the seat becomes longer; thereby, the position change of the pedal body 2 during the adjustment process is more in line with the change in the position of the child's feet as the child grows, and is more ergonomic.
[0061] In some embodiments of the present application, a gear adjustment mechanism is arranged between the support portion 320 and the pedal body 2, and the gear adjustment mechanism includes a gear switching member 4, on which a bayonet 401 is arranged, and a plurality of slots 321 which are engaged with the bayonet 401 are opened along the length direction on the support portion 320; the gear switching member 4 is rotatably connected to the pedal body 2, and a avoidance hole 201 which is connected to the sliding groove 210 is arranged on the side wall of the pedal body 2, and the bayonet 401 penetrates into the avoidance hole 201; when the pedal body 2 slides up and down relative to the support portion 320, the bayonet 401 avoids the slot 321; when the pedal body 2 is fixed to the support portion 320, the bayonet 401 penetrates into the avoidance hole 201 and is engaged with the slot 321 in the sliding groove 210.
[0062] In this embodiment, the gear position is adjusted by means of the engagement of the latch 401 and the slot 321, which not only makes the gear position adjustment operation easier, but also increases the connection strength between the pedal body 2 and the support portion 320 after the gear position is fixed.
[0063] In some embodiments of the present application, a mounting groove 220 is provided at the rear end of the pedal body 2, and the gear switching member 4 is installed in the mounting groove 220. The gear switching member 4 includes a lower pushing portion 410 and an upper resetting portion 420. The middle portion of the gear switching member 4 and the mounting groove 220 are rotatably connected via a rotating shaft, so that the pushing portion 410 and the resetting portion 420 can rotate synchronously around the rotating shaft; the pin 401 is connected to the pushing portion 410, and the avoidance hole 201 is provided in the mounting groove 220. An elastic member 221 is provided between the mounting groove 220 and the resetting portion 420. The elastic member 221 pushes the resetting portion 420, so that the resetting portion 420 always has a tendency to rotate backward, thereby driving the pushing portion 410 to have a tendency to rotate toward the mounting groove 220, so that the pin 401 can always have a tendency to be inserted into the slot 321.
[0064] In this embodiment, an elastic member 221 is provided between the mounting groove 220 and the reset portion 420 so that the latch 401 always tends to be inserted into the latch slot 321, thereby allowing the pedal body 2 to be stably fixed to the support portion 320 during use; and the user can press the reset portion 420 to drive the push portion 410 to rotate outward around the rotation axis, so that the latch 401 avoids the latch slot 321, thereby allowing the pedal body 2 to slide freely on the support portion 320 again for adjustment, making the adjustment operation of the pedal body 2 very simple.
[0065] The elastic member 221 may be a spring, a torsion spring, rubber, etc. Preferably, the elastic member 221 is a torsion spring, which is sleeved on the rotating shaft, and one torsion arm of the torsion spring abuts against the mounting slot 220, and the other torsion arm abuts against the reset portion 420. The torsion spring not only has good elasticity, but also has high strength. When the user presses the reset portion 420, the two torsion arms of the torsion spring approach each other and drive the torsion spring to twist, so that the torsion spring can apply a sufficiently large torsion force to the reset portion 420, so that after the user releases the reset portion 420, the reset portion 420 can be automatically reset.
[0066] In some embodiments of the present application, a foot pad 5 is connected to the bottom of the support portion 320, a threaded hole is provided at the bottom end of the support portion 320, a threaded rod is threadedly connected to the threaded hole, a spherical joint 322 protrudes from the lower end of the threaded rod, a spherical groove 501 is provided at the upper end of the foot pad 5, and the spherical joint 322 is inserted into the spherical groove 501, so that the foot pad 5 can rotate in all directions relative to the support portion 320.
[0067] In this embodiment, when the support rod 3 is subjected to pressure from the user's foot, the foot pad 5 is pressed into contact with the ground, which not only provides support for the support rod 3 and improves stability, but also prevents the support portion 320 from contacting the ground, thereby preventing the support portion 320 made of a harder material from scratching the floor; more than that, the foot pad 5 can rotate in all directions around the ball joint 322, so that the foot pad 5 can automatically rotate to fit the ground regardless of the height and inclination, thereby further improving stability.
[0068] Among them, the threaded rod is screwed to the bottom end of the support part 320, which not only makes the loading and unloading operations of the ball joint 322 simpler, but also the user can adjust the distance between the foot pad 5 and the support part 320 by adjusting the depth of the threaded rod, that is, the distance between the ball joint 322 and the support part 320.
