Description

Technical Field

[0001] The present invention relates to the field of seats, and particularly to a pedal structure for a seat. Background Art

[0002] For the seats on the market currently, generally a rotatable pedal structure is provided at the bottom thereof. The pedal structure includes a pedal. When the pedal is rotated out to a set angle, it can support the sole of the user, so that the legs of the user, especially the sole part, can be sufficiently relaxed.

[0003] For the current seats, the pedal structure includes a fixed cross beam, a cantilever, a support arm and a spring. The cantilever is fixed on the fixed cross beam. The support arm is hinged to the lower end of the cantilever by a shaft. The pedal is fixed on the support arm. The two ends of the spring are respectively hooked on the cantilever and the support arm, and the spring is located at the rear side of the cantilever and the support arm. When the pedal is in the unfolded state, the force of the spring can pull the pedal so that the pedal remains in the unfolded state (i.e., the state where it can support the sole of the user). When it is necessary to retract the pedal, it is necessary to lift the pedal around the hinge axis so that the pedal is close to the cantilever. At this time, the spring is in a U shape and the support arm is at a dead point and cannot be unfolded. The existence of the cantilever, the support arm and the external spring in the prior art increases the volume of the pedal structure.

[0004] In view of this, it is necessary to design a pedal structure for a seat to reduce the volume of the pedal structure. Summary of the Invention

[0005] The purpose of the present invention is to provide a pedal structure for a seat to reduce the volume of the pedal structure.

[0006] To achieve this purpose, the present invention adopts the following technical solutions:

[0007] A pedal structure for a seat includes a support shaft, a pedal, a rotating sleeve and an elastic member; the pedal is provided with a sleeve portion rotatably sleeved on the support shaft, and the rotating sleeve is rotatably sleeved on the sleeve portion;

[0008] A positioning groove is formed on the outer peripheral surface of the support shaft. A through groove corresponding to the positioning groove is formed in the sleeve portion. A positioning roller is arranged in the through groove. A positioning portion for pressing the positioning roller and a groove adjacent to the positioning portion are arranged on the inner wall of the rotating sleeve;

[0009] The elastic member is elastically bent and arranged between the sleeve portion and the rotating sleeve. The elastic member is used to keep the relative positions of the sleeve portion and the rotating sleeve unchanged, so that the positioning portion can face the through groove to press and position the positioning roller;

[0010] When the rotating sleeve rotates under force to align the groove with the positioning groove, the elastic member is compressed, and the side groove wall of the through groove pushes the positioning roller away from the positioning groove, so that the pedal can rotate relative to the support shaft.

[0011] Optionally, a through first limiting groove is provided at one end of the sleeve portion, and a second limiting groove is provided on the rotating sleeve corresponding to the first limiting groove;

[0012] The elastic member includes a first pin, an arc connecting portion and a second pin connected end to end in sequence. The first pin and the second pin both pass through the first limiting groove and enter the second limiting groove; the first pin and the second pin respectively abut against the opposite side groove walls of the first limiting groove, and the first pin and the second pin respectively abut against the opposite side groove walls of the second limiting groove.

[0013] Optionally, a plurality of the positioning grooves are arranged at intervals on the outer peripheral surface of the support shaft, a through groove corresponding to the plurality of positioning grooves is provided on the sleeve portion, and grooves corresponding to the plurality of positioning grooves are provided on the inner wall of the rotating sleeve.

[0014] Optionally, grooves are provided on both opposite sides of the positioning portion, and the distance from the bottom of the groove to the outer peripheral surface of the support shaft is not less than the diameter of the positioning roller.

[0015] Optionally, the distance from the bottom of the positioning groove to the rotating sleeve is equal to the diameter of the positioning roller.

[0016] Optionally, the cross-section of the positioning groove perpendicular to the axis of the support shaft is U-shaped, and the side groove wall of the positioning groove is smoothly transitioned with the outer peripheral surface of the support shaft.

[0017] Optionally, the pedal further includes a main body and a connecting and supporting portion, and the main body is fixedly connected to the sleeve portion through the connecting and supporting portion.

[0018] Optionally, the pedal structure for a seat further includes a base and a slide rail provided on one side of the bottom of the base;

[0019] The support shaft is slidably connected to the slide rail through a connecting rod, and the support shaft is fixedly connected to the connecting rod.

[0020] Optionally, the pedal structure for a seat further includes a rotating shaft;

[0021] Two groups of slide rails are arranged at intervals on one side of the bottom of the base, the connecting rod is provided on each group of slide rails, and the support shaft is provided on each connecting rod;

[0022] The support shaft is provided with a through hole along its axial direction, and the rotating shaft is inserted into the through holes of the two support shafts; the pedal is provided with two sleeve parts corresponding to the two support shafts, and each sleeve part is sleeved with a rotating sleeve;

[0023] A handle can be rotatably sleeved on the rotating shaft, and opposite ends of the handle are respectively clamped with the two rotating sleeves.

[0024] Optionally, a first groove is provided on the outer peripheral wall of the sleeve portion, and a second groove is provided on the inner wall of the rotating sleeve corresponding to the first groove;

[0025] When the rotating sleeve is arranged on the sleeve part, the first groove and the second groove form a mounting groove for installing the elastic member, and the elastic member is elastically bent around the axis of the support shaft; the two ends of the elastic member respectively abut against the two side walls opposite to each other of the first groove, and the two ends of the elastic member respectively abut against the two side walls opposite to each other of the second groove.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] In this embodiment, when the positioning roller is placed in the positioning groove and the positioning part is facing the positioning groove, the positioning roller cannot roll out of the positioning groove. Under the elastic force of the elastic member, the positioning roller is equivalent to a block to achieve the fixation between the sleeve part and the support shaft; when the pedal needs to be rotated, the rotating sleeve is forced to rotate so that the groove is aligned with the positioning groove, the elastic member is compressed and the side groove wall of the groove penetrates the groove to push the positioning roller from the positioning groove to the groove. At this time, the positioning roller is completely separated from the positioning groove so that the sleeve part can rotate around the support shaft. In this embodiment, there is no need to set a cantilever, a supporting arm and a spring exposed to the outside. The positioning of the pedal is achieved through a clever structural design, which greatly reduces the volume of the pedal structure. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be an intermediate component.

[0044] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0045] Embodiment 1

[0046] Please refer to Figures 1 to 10 , the embodiment of the present invention provides a pedal structure for a seat, including a support shaft 1, a pedal 2, a rotating sleeve 3, and an elastic member 4;

[0047] The pedal 2 is provided with a sleeve portion 21, and the sleeve portion 21 is rotatably sleeved on the support shaft 1; the rotating sleeve 3 is rotatably sleeved on the sleeve portion 21;

[0048] A positioning groove 11 is formed on the outer peripheral surface of the support shaft 1, and a through groove 211 is correspondingly formed in the sleeve portion 21 corresponding to the positioning groove 11. In this embodiment, the cross-section of the through groove 211 is rectangular. A positioning roller 5 is arranged in the through groove 211, and a positioning portion 31 for pressing the positioning roller 5 and a groove 32 adjacent to the positioning portion 31 are arranged on the inner wall of the rotating sleeve 3.

[0049] The elastic member 4 is elastically bent and disposed between the sleeve portion 21 and the rotating sleeve 3. The elastic member 4 is used to keep the relative positions of the sleeve portion 21 and the rotating sleeve 3 unchanged, so that the positioning portion 31 can be directly opposite to the through groove 211 to press and position the positioning roller 5. When the installation is completed, the force for the elastic member 4 to recover its elastic deformation keeps the relative positions of the sleeve portion 21 and the rotating sleeve 3 unchanged. It should be noted that when the rotating sleeve 3 is forced to rotate so that the groove 32 is aligned with the positioning groove 11, the elastic member 4 is compressed and the side groove wall of the through groove 211 pushes the positioning roller 5 from the positioning groove 11 to the groove 32. At this time, the positioning roller 5 completely disengages from the positioning groove 11, enabling the sleeve portion 21 to rotate around the support shaft 1, achieving the purpose of the pedal 2 rotating around the support shaft 1.

[0050] When the rotating sleeve 3 is forced to rotate so that the groove 32 is aligned with the positioning groove 11, the elastic member 4 is compressed, and the side groove wall of the through groove 211 can push the positioning roller 5 from the positioning groove 11 to the groove 32. At this time, the positioning roller 5 is between the outer peripheral surface of the support shaft 1 and the groove 32, and at this time, the pedal 2 can rotate relative to the support shaft 1.

[0051] In this embodiment, through a clever structural design, without setting a cantilever, a support arm and an external spring, the pedal 2 can be fixed in the unfolded state (that is, when the pedal 2 is at an angle for bearing the user's sole), reducing the volume of the pedal structure. When the positioning roller 5 is in the positioning groove 11 and the positioning portion 31 presses on the positioning roller 5, the side wall of the through groove 211 cannot push the positioning roller 5 out of the positioning groove 11, which is equivalent to the sleeve portion 21 being clamped by the positioning roller 5, and the pedal 2 can maintain the unfolded state. When the positioning portion 31 is directly above the positioning groove 11, at this time, the positioning roller 5 cannot apply a torsion force to the positioning portion 31, that is, it cannot make the rotating sleeve 3 rotate relative to the sleeve portion 21, so that the pedal 2 is always in the unfolded state. In addition, the elastic member 4 will not be exposed outside, which can increase the service life of the elastic member 4.

[0052] Optionally, a through first limiting groove 212 is provided at one end of the sleeve portion 21, and a second limiting groove 33 is provided on the rotating sleeve 3 corresponding to the first limiting groove 212;

[0053] The elastic member 4 includes a first pin 41, an arc connecting portion 42 and a second pin 43 that are sequentially connected end to end. Both the first pin 41 and the second pin 43 pass through the first limiting groove 212 and enter the second limiting groove 33;

[0054] The first pin 41 and the second pin 43 respectively abut against the opposite side groove walls of the first limiting groove 212, and the first pin 41 and the second pin 43 respectively abut against the opposite side groove walls of the second limiting groove 33.

[0055] Specifically, since the elastic member 4 is elastically bent and disposed between the sleeve portion 21 and the rotating sleeve 3. The first pin 41 has a tendency to move away from the second pin 43, and the second pin 43 has a tendency to move away from the first pin 41, so that the sleeve portion 21 and the rotating sleeve 3 maintain their relative positions unchanged (i.e., the relative rotation angle remains unchanged); at this time, when no torsional force is applied to the rotating sleeve 3 from the outside, the pedal 2 can always remain in the unfolded state.

[0056] Optionally, a plurality of positioning grooves 11 are provided at intervals on the outer peripheral surface of the support shaft 1, the sleeve portion 21 is provided with through grooves 211 corresponding to the plurality of positioning grooves 11 one by one, and grooves 32 corresponding to the plurality of positioning grooves 11 one by one are provided on the inner wall of the rotating sleeve 3.

[0057] Specifically, a plurality of positioning grooves 11 can be provided at intervals on the outer peripheral surface of the support shaft 1 as needed, so that the pedal 2 can have multiple positioning positions to meet the need of the pedal 2 to support the sole of the foot at different angles. In addition, the need to store the pedal 2 can also be met, that is, a support shaft 1 is provided on the support shaft 1 at an angle where the pedal 2 can be stored.

[0058] Optionally, grooves 32 are provided on both opposite sides of the positioning portion 31, and the distance from the bottom of the groove 32 to the outer peripheral surface of the support shaft 1 is not less than the diameter of the positioning roller 5. Specifically, rotating the rotating sleeve 3 clockwise and counterclockwise can both make the positioning roller 5 enter the groove 32, so that the sleeve portion 21 can push the positioning roller 5 to realize the rotation of the pedal 2.

[0059] Optionally, the distance from the bottom of the positioning groove 11 to the rotating sleeve 3 is equal to the diameter of the positioning roller 5, so that the inner hole wall of the rotating sleeve 3 constitutes the positioning portion 31, which is convenient for the processing and forming of the rotating sleeve 3.

[0060] Optionally, the cross-section of the positioning groove 11 perpendicular to the axis of the support shaft 1 is U-shaped, and the side groove wall of the positioning groove 11 is smoothly transitioned with the outer peripheral surface of the support shaft 1, so that the positioning roller 5 can more easily roll out of the positioning groove 11 under the push of the sleeve portion 21, which is convenient for the operator to operate.

[0061] Optionally, the pedal 2 further includes a main body 22 and a connecting support portion 23, and the main body 22 is fixedly connected to the sleeve portion 21 through the connecting support portion 23. The main body 22 constitutes the main component for supporting the sole of the foot.

[0062] Optionally, the pedal structure for a seat further includes a base and a slide rail provided on one side of the bottom of the base;

[0063] The support shaft 1 is slidably connected to the slide rail through the connecting rod 6, and the support shaft 1 is fixedly connected to the connecting rod 6. Specifically, when the pedal 2 is not needed, the pedal 2 can be flipped to the storage position and then pushed into one side of the bottom of the base through the slide rail. That is, the user can use the footrest 2 or choose not to use the footrest 2. When the footrest 2 is not used, the footrest 2 is pushed into the bottom of the base, and at this time, the footrest 2 will not be exposed outside to form an obstacle to the user's use.

[0064] Optionally, the pedal structure for the seat further includes a rotating shaft 7;

[0065] Two sets of slide rails are spaced apart on one side of the bottom of the base. A connecting rod 6 is provided on each set of slide rails, and a support shaft 1 is provided on each connecting rod 6;

[0066] The support shaft 1 is provided with a through hole along its axial direction, and the rotating shaft 7 passes through the through holes of the two support shafts 1; the pedal 2 is provided with two sleeve portions 21 corresponding to the two support shafts 1, and a rotating sleeve 3 is sleeved on each sleeve portion 21;

[0067] A handle 8 is also rotatably sleeved on the rotating shaft 7, and the opposite ends of the handle 8 are respectively clamped to the two rotating sleeves 3. Specifically, the two support shafts 1 jointly support a pedal 2, improving the support stability of the pedal 2. In addition, the handle 8 can drive the two rotating sleeves 3 to rotate simultaneously to realize the angle adjustment of the pedal 2. It should be clear that the arc-shaped connecting portion 42 of the elastic member 4 is sleeved on the rotating shaft 7.

[0068] Embodiment 2

[0071] The elastic member 4 is elastically bent and arranged between the sleeve portion 21 and the rotating sleeve 3. The elastic member 4 is used to keep the relative position between the sleeve portion 21 and the rotating sleeve 3 unchanged, so that the positioning portion 31 can face the through groove 211 to press the positioning roller 5;

[0072] When the rotating sleeve 3 is rotated by force to align the groove 32 with the positioning groove 11, the elastic member 4 is compressed, and the side groove wall of the through groove 211 can push the positioning roller 5 from the positioning groove 11 to the groove 32, and at this time, the pedal 2 can rotate relative to the support shaft 1.

[0073] Optionally, a first groove 201 is provided on the outer peripheral wall of the sleeve portion 21, and a second groove 301 is correspondingly provided on the inner wall of the rotating sleeve 3 for the first groove 201. Please refer to Figure 11 , when the rotating sleeve 3 is sleeved on the sleeve portion 21, the first groove 201 and the second groove 301 form a mounting groove for mounting the elastic member 4, and the elastic member 4 is elastically bent around the axis of the support shaft 1; both ends of the elastic member 4 respectively abut against opposite side walls of the first groove 201, and both ends of the elastic member 4 respectively abut against opposite side walls of the second groove 301. In this embodiment, the elastic member 4 is a spring. It should be clear that when the rotating sleeve 3 rotates, the spring will be further compressed, and the sleeve portion 21 will be pushed to rotate by the spring. The structures of the rotating sleeve 3 and the sleeve portion 21 in this embodiment are simpler and easier to process and form.
