Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a footstool and a chair. Background Technology

[0002] To improve seating comfort, some seats are equipped with footrests, allowing users to rest their legs. However, some footrests have a fixed angle, making them difficult to adapt to different user needs. Others are adjustable, but the adjustment mechanism is complex; for example, tools are needed to turn a screw to unlock the footrest, and then the screw must be tightened again to lock the footrest in its position, resulting in poor usability. Therefore, there is an urgent need for a footrest with an easily adjustable angle. Utility Model Content

[0003] The purpose of this utility model is to provide a footrest and seat to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is: A foot pedal includes: a pedal with a connecting sleeve, the inner side of which is provided with a plurality of stop grooves; a connecting shell with a first connecting head and a second connecting head spaced apart, the connecting sleeve being located between the first connecting head and the second connecting head, the first connecting head having a connecting seat extending into the connecting sleeve, the outer side of the connecting seat having receiving grooves corresponding to the positions of the plurality of stop grooves, and the second connecting head having a locking assembly, the locking assembly including a transmission part and a plurality of locking members pulsatorically connected to the transmission part, the transmission part being capable of driving the plurality of locking members to enter or exit the plurality of receiving grooves respectively.

[0005] This technical solution has at least the following beneficial effects: the connecting shell is used to connect to the structural components of the external device for fixation, such as the rod extending forward from the seat, while the connecting sleeve on the pedal is located between the first connecting head and the second connecting head. By inserting the connecting seat into the connecting sleeve, the pedal and the connecting shell can be rotated relative to each other, thereby adjusting the rotation angle of the pedal. Specifically, when the pedal does not need to rotate, the transmission unit can drive multiple locking parts to exit from multiple receiving slots. At this time, the multiple locking parts are located in multiple stop slots inside the connecting sleeve. When the pedal angle needs to be adjusted, the transmission unit drives multiple locking parts to move into multiple receiving slots. At this time, the locking parts are not stopped by the stop slots of the connecting sleeve, and the connecting sleeve can rotate relative to the connecting shell under the action of external force, thereby adjusting the rotation angle of the pedal. After the pedal is adjusted to the correct position, the transmission unit can drive multiple locking parts to exit from multiple receiving slots again. At this time, the locking parts enter the stop slots of the connecting sleeve, thereby restricting the relative rotation of the connecting sleeve and locking the position of the pedal after rotation adjustment. This allows for quick rotation adjustment and locking of the pedal, greatly improving the overall ease of operation and user experience.

[0006] As a further improvement to the above technical solution, the transmission part includes a transmission cylinder and a transmission rod. The transmission cylinder is sleeved on the outside of the connecting seat, and the transmission rod is connected to the transmission cylinder and extends out of the second connecting head. The transmission cylinder is provided with a connecting hole corresponding to the positions of the multiple locking members, and the multiple locking members extend into the multiple connecting holes respectively.

[0007] As a further improvement to the above technical solution, the transmission part further includes an elastic element, which is disposed between the connecting seat and the transmission cylinder, and the elastic element has a tendency to press the transmission cylinder against the second connecting head.

[0008] As a further improvement to the above technical solution, the elastic element is a spring, one end of which is disposed on the connecting seat and the other end of which is disposed on the transmission cylinder.

[0009] As a further improvement to the above technical solution, when the transmission cylinder moves to abut against the first connector, it can drive the multiple locking members to enter the multiple receiving slots respectively.

[0010] As a further improvement to the above technical solution, the second connector is provided with an anti-loosening sleeve, which is inserted into the transmission cylinder. The end of the connecting sleeve near the second connector forms a limiting shoulder, which abuts against the outside of the anti-loosening sleeve. The transmission rod passes through the anti-loosening sleeve.

[0011] As a further improvement to the above technical solution, the transmission rod and the transmission cylinder are detachably connected.

[0012] As a further improvement to the above technical solution, the locking element is spherical in shape.

[0013] As a further improvement to the above technical solution, a fixing member is provided on the end face of the first connector away from the second connector, and the fixing member is detachably connected to the connector seat.

[0014] A seat includes a seat and the aforementioned footrest, wherein a connecting rod is connected to the bottom side of the seat and the connecting rod is connected to the connecting shell.

[0015] This technical solution has at least the following beneficial effects: In this chair seat, the connecting rod on the bottom side of the seat connects and fixes the connecting shell. The user's feet can rest on the pedal. During normal use, the pedal is in a stationary and non-adjustable state. At this time, multiple locking parts are located in multiple stop grooves inside the connecting sleeve. When it is necessary to rotate and adjust the angle of the pedal, the transmission part drives the multiple locking parts to move into the multiple receiving grooves. At this time, the locking parts are not stopped and limited by the stop grooves of the connecting sleeve. The connecting sleeve can rotate relative to the connecting shell under the action of external force, thereby adjusting the angle of the pedal. After the pedal is adjusted to the correct position, the transmission part can drive the multiple locking parts to exit the multiple receiving grooves again. At this time, the locking parts enter the stop grooves of the connecting sleeve, thereby restricting the relative rotation of the connecting sleeve and realizing the locking of the position after the pedal is rotated and adjusted. In this way, the pedal can be quickly rotated, adjusted and locked, which greatly improves the overall ease of operation and user experience.

[0028] Reference Figure 1 A foot pedal includes a pedal 100 and a connecting shell 200. The pedal 100 is provided with a connecting sleeve 110, and the inner side of the connecting sleeve 110 is provided with a plurality of stop grooves 111. The connecting shell 200 is provided with a first connector 210 and a second connector 220 at intervals. The connecting sleeve 110 is located between the first connector 210 and the second connector 220. The first connector 210 is provided with a connecting seat 230 extending into the connecting sleeve 110. The outer side of the connecting seat 230 is provided with receiving grooves 231 corresponding to the positions of the plurality of stop grooves 111. The second connector 220 is provided with a locking assembly. The locking assembly includes a transmission part and a plurality of locking members 240 that are pulverically connected to the transmission part. The transmission part can drive the plurality of locking members 240 to enter or exit the plurality of receiving grooves 231 respectively.

[0029] As described above, the connecting shell 200 is used to connect to and fix the structural components of the peripheral device, such as the forward-extending rod of the seat. The connecting sleeve 110 on the pedal 100 is located between the first connecting head 210 and the second connecting head 220. By inserting the connecting seat 230 into the connecting sleeve 110, the pedal 100 and the connecting shell 200 can rotate relative to each other, thereby adjusting the rotation angle of the pedal 100. Specifically, when the pedal 100 does not need to rotate, the transmission unit can drive multiple locking members 240 to exit multiple receiving slots 231 respectively. At this time, the multiple locking members 240 are located in multiple stop slots 111 inside the connecting sleeve 110. When it is necessary to rotate and adjust the angle of the pedal 100, the transmission unit drives... Multiple locking elements 240 move into multiple receiving slots 231 respectively. At this time, the locking elements 240 are not stopped and limited by the stop groove 111 of the connecting sleeve 110. The connecting sleeve 110 can rotate relative to the connecting shell 200 under the drive of external force, thereby adjusting the angle of the pedal 100. After the pedal 100 is adjusted to the position, the multiple locking elements 240 can be driven out of the multiple receiving slots 231 again through the transmission part. At this time, the locking elements 240 enter the stop groove 111 of the connecting sleeve 110, thereby restricting the relative rotation of the connecting sleeve 110 and realizing the position locking of the pedal 100 after rotation adjustment. In this way, the pedal 100 can be quickly rotated and locked, which greatly improves the overall operation convenience and user experience.

[0030] The transmission part is mainly used to drive multiple locking members 240 into or out of the receiving groove 231. In this embodiment, the transmission part includes a transmission cylinder 251 and a transmission rod 252. The transmission cylinder 251 is sleeved on the outside of the connecting seat 230. The transmission rod 252 passes through the second connecting head 220 and is connected to the transmission cylinder 251. The transmission cylinder 251 is provided with a connecting hole 253 corresponding to the position of the multiple locking members 240. The multiple locking members 240 extend into the multiple connecting holes 253 respectively. The transmission cylinder 251 is located between the outer side of the connecting seat 230 and the inner side of the connecting sleeve 110, and can move axially along the connecting sleeve 110. When it is necessary to lock the position of the pedal 100, the transmission cylinder 251 is moved towards the first connecting head 210, so that the multiple connecting holes 253 on the transmission cylinder 251 are aligned with the multiple receiving grooves 231. At this time, the receiving grooves 231 are interconnected with the stop groove 111 through the connecting holes 253, and the locking member 240 can enter the receiving groove 231 or the stop groove 111. When the connecting sleeve 110 is rotated, the locking member 240 located in the stop groove 111 can be locked. The locking element 240 inside is squeezed into the receiving groove 231, so that multiple locking elements 240 enter the receiving groove 231 respectively, without interfering with the rotation of the connecting sleeve 110. After the rotation adjustment of the pedal 100 is completed, multiple stop grooves 111 are also aligned with multiple receiving grooves 231 respectively. At this time, the transmission cylinder 251 is moved towards the second connector 220, which drives multiple locking elements 240 to leave the empty groove and enter the stop groove 111 that is aligned with it, thereby restricting the relative rotation of the connecting sleeve 110 and realizing the relocking of the pedal 100.

[0031] To better retain the locking member 240 out of the receiving groove and keep the pedal 100 locked, in this embodiment, the transmission part further includes an elastic member 254. The elastic member 254 is disposed between the connecting seat 230 and the transmission cylinder 251. The elastic member 254 has a tendency to press the transmission cylinder 251 against the second connecting head 220. When no external force is applied to the transmission part, the elastic member 254 presses the transmission cylinder 251 against the second connecting head 220. At this time, the locking member 240 exits the receiving groove 231 and extends into the stop groove 111, which can effectively maintain the state of restricting the rotation of the connecting sleeve 110. When it is necessary to rotate the pedal 100, an axial force is applied to the transmission cylinder 251, causing the elastic member 254 to elastically deform until the locking member 240 on the transmission cylinder 251 can enter into the receiving groove 231, so that the connecting sleeve 110 can be rotated and adjusted.

[0032] The elastic element 254 can take various structural forms, such as torsion springs or elastic materials like rubber. In this embodiment, the elastic element 254 is a spring, with one end of the spring disposed on the connecting seat 230 and the other end of the spring disposed on the transmission cylinder 251. The spring provides elastic force to the transmission cylinder 251, causing it to press against the second connecting head 220, thus providing stable axial pressure to the transmission cylinder 251. In practical applications, a positioning groove 232 can be provided on the end face of the connecting seat 230 near the second connecting head 220, and a positioning post 255 can be formed on the inner side of the end face of the transmission cylinder 251 near the second connecting head 220. This limits the movement of both ends of the spring, improving its stability.

[0033] To better control the travel of the transmission cylinder 251, in this embodiment, when the transmission cylinder 251 moves to abut against the first connector 210, it can drive the multiple locking members 240 to enter the multiple receiving slots 231 respectively. When the transmission cylinder 251 is moved towards the first connector 210, it can be directly and quickly pressed against the first connector 210. When the transmission cylinder 251 abuts against the first connector 210, the multiple locking members 240 on the transmission cylinder 251 also move to face the multiple receiving slots 231, so that the multiple locking members 240 can enter the multiple receiving slots 231 respectively.

[0034] To improve the stability of the transmission rod 252's movement, in this embodiment, the second connector 220 is provided with an anti-loosening sleeve 260, which is inserted into the transmission cylinder 251. The end of the connecting sleeve 110 near the second connector 220 forms a limiting shoulder 112, which abuts against the outside of the anti-loosening sleeve 260. The transmission rod 252 passes through the anti-loosening sleeve 260. By using the limiting shoulder 112 to abut against the outside of the anti-loosening sleeve 260, the anti-loosening sleeve 260 can be limited in the circumferential direction, thereby strengthening the tightness between the second connector 220 and the connecting sleeve 110, making the rotation of the connecting sleeve 110 and the second connector 220 more stable. At this time, the transmission rod 252 passes through the middle of the anti-loosening sleeve 260 and is connected to the transmission cylinder 251. The transmission rod 252 drives the transmission cylinder 251 to move synchronously. In practical applications, a transmission cap can also be provided at the end of the transmission rod 252 away from the transmission cylinder 251. The outer diameter of the transmission cap is larger than the outer diameter of the transmission rod 252. When it is necessary to push the transmission rod 252, force can be applied to the transmission cap, making it easier to drive the transmission rod 252 to move.

[0035] In some embodiments, the transmission rod 252 and the transmission cylinder 251 are detachably connected. For example, the transmission rod 252 and the transmission cylinder 251 can be connected by threads or by snap-fit. When it is necessary to insert the connecting sleeve 110 between the first connector 210 and the second connector 220, the transmission rod 252 and the transmission cylinder 251 are detached. The connecting sleeve 110 is inserted between the first connector 210 and the second connector 220, then the anti-loosening sleeve 260 is inserted, and then the transmission rod 252 is connected to the transmission cylinder 251, thereby realizing the assembly of the whole.

[0036] To improve the smoothness of movement of the locking member 240, in this embodiment, the locking member 240 is spherical. The spherical locking member 240 is more convenient to enter and exit the receiving groove 231, thereby improving the smoothness of rotation and locking of the connecting sleeve 110.

[0037] In some embodiments, a fixing member 270 is provided on the end face of the first connector 210 away from the second connector 220. The fixing member 270 is detachably connected to the connector 230. In practical applications, the fixing member 270 can be connected to the connector 230 by means of clips or screws. Connecting the connector 270 to the connector 230 through the fixing member 270 facilitates the removal and installation of the connector 230 from the first connector 210, thereby improving the convenience of overall assembly.

[0038] A seat includes a seat and the aforementioned footrest, wherein a connecting rod is connected to the bottom side of the seat and the connecting rod is connected to the connecting housing 200.

[0039] In this chair seat, the connecting rod on the bottom side of the seat connects and fixes the connecting shell 200. The user's feet can rest on the pedal 100. During normal use, the pedal 100 is in a stationary and non-adjustable state. At this time, multiple locking elements 240 are respectively located in multiple stop grooves 111 inside the connecting sleeve 110. When it is necessary to rotate and adjust the angle of the pedal 100, the multiple locking elements 240 are driven by the transmission part to move into multiple receiving grooves 231. At this time, the locking elements 240 are not stopped and limited by the stop grooves 111 of the connecting sleeve 110. The sleeve 110 can rotate relative to the connecting shell 200 under the action of an external force, thereby adjusting the angle of the pedal 100. After the pedal 100 is adjusted to the correct position, the transmission part can drive multiple locking parts 240 to exit multiple receiving slots 231 respectively. At this time, the locking parts 240 enter the stop slot 111 of the connecting sleeve 110, thereby restricting the relative rotation of the connecting sleeve 110 and locking the position of the pedal 100 after rotation adjustment. This allows for quick rotation adjustment and locking of the pedal 100, greatly improving the overall ease of operation and user experience.

[0040] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
