Abstract
Description
Technical Field
[0001] This application relates to the technical field of seat structures, and in particular to a seat structure having a multi-segment unfolded state. Background Technology
[0002] Typically, chairs are not just seats and legs; they also include backrests, headrests, and other components. On some chairs, armrests are typically installed vertically on both sides of the seat to provide support for the user's hands when seated. However, in actual use, users may need the armrests to gather their arms in certain situations, while not needing them in others. In other words, the position of the armrests often varies depending on the user's actual posture, and the current fixed vertical armrests on the seat cannot meet this requirement. Utility Model Content
[0003] In order to provide armrests with multiple unfolding states to adapt to the user's usage, this application provides a seat structure with multiple unfolding states.
[0004] This application provides a seat structure with a multi-section unfolded state, which adopts the following technical solution: A seat structure with a multi-section unfolded state includes a stool and armrests disposed on both sides of the stool. The armrests have a connecting bracket connected to the stool. One end of the connecting bracket has a rotating disk. At least one side of the stool is provided with a mating base. The mating base has a rotating groove for the rotating disk to be inserted and rotated.
[0005] The rotating disk is rotatably disposed in the rotating groove, and a snap-fit block is provided at the mating base. The snap-fit block is connected to the mating base through an elastic element. The elastic element is used to make the snap-fit block snap into the rotating disk radially, so as to limit the angle between the rotating disk and the mating base.
[0006] By adopting the above technical solution, the armrests can be connected to the seat by a connecting bracket, and the seat can be rotated relative to the seat. One or all of the armrests can rotate individually. After rotation, the locking block is engaged with the rotating plate, which will limit the angle of the rotating plate, thereby realizing multiple unfolding positions for the user to choose from.
[0007] Preferably, the elastic element is a spring, which is radially disposed on the mating base along the rotating disk. The rotating disk has several limiting grooves evenly distributed around its periphery, and a portion of the snap-fit block is used to insert into the limiting groove.
[0008] Preferably, the snap-fit block includes a sliding section slidably connected to the mating base and a mating section disposed at the end of the sliding section. The mating section is a cylinder with a semi-circular cross-section, and the arc surface of the mating section is used to engage and abut against the edge of the limiting groove. The spring is sleeved on the sliding section, one end of the spring is connected to the mating section, and is used to drive the mating section to be embedded into the limiting groove. The other end of the spring is connected to the mating base.
[0009] Preferably, the sliding section does not extend into the limiting groove, and the connection portion between the mating section and the sliding section is located outside the limiting groove.
[0010] Preferably, a stop bar is provided on the mating base and located outside the rotating groove. The stop bar is used to insert into the limiting groove along the rotation axis of the rotating disk. The mating base is provided with a driving member to drive the stop bar to move.
[0011] By adopting the above technical solution, when the limiting firmness of the locking block is insufficient, an additional driving component is added to drive the stop rod to be inserted into the rotating disk, so that the rotating disk is completely limited to the mating base. When adjustment is required again, the stop rod can be removed from the rotating disk.
[0012] Preferably, the driving component includes a connecting post fixedly connected to the outer wall of the mating base, a driving ring threaded to the outer wall of the connecting post, a rotating ring rotatably connected to the end of the driving ring, and a stop bar fixedly disposed on the rotating ring.
[0013] Preferably, the mating base has a receiving groove in the radial direction, the snap-fit block is slidably disposed in the receiving groove, the end of the sliding section away from the mating section passes through the mating base, and this end is provided with a limiting piece.
[0014] In summary, this application includes at least one of the following beneficial technical effects:
[0015] 1. The armrests can be connected to the seat by connecting brackets, allowing the seat to rotate relative to the seat. One or all armrests can rotate individually. The locking block can be locked to the rotating plate, which will limit the angle of the rotating plate, thereby realizing multiple unfolding positions for the user to choose from.
[0016] 2. When the locking block is not secure enough, add an additional drive component to insert a drive lever into the rotating disk, so that the rotating disk is completely locked in place by the mating base. When adjustment is needed again, simply remove the lever from the rotating disk. Attached Figure Description

Detailed Implementation
[0025] The present application will be further described in detail below with reference to the accompanying drawings.
[0026] This embodiment discloses a seat structure with multiple unfolded sections, referring to... Figure 1 , Figure 2 , Figure 3 The product includes a seat 100 and armrests 110 on both sides of the seat 100. The figure only shows the internal frame structure and not the complete structure. Specifically, at least the outer side of the seat 100 has a sponge pad, and the armrests 110 also have an outer covering. The armrests 110 have a connecting bracket 111 connected to the seat 100. One end of the connecting bracket 111 has a rotating disk 112. At least one side of the seat 100 is provided with a mating base 113, which has a rotating groove 114 for the rotating disk 112 to be inserted and rotated. It is worth noting that the mating base 113 can be provided on both sides of the seat 100, or only on one side, or on three or more sides, depending on the actual product requirements.
[0027] In this embodiment, a structure is described where the stool 100 has mating bases 113 on both sides. In this embodiment, the mating bases 113 have rotating grooves 114 that divide them into two halves. These halves are approximately two cylindrical objects, with rotating disks 112 embedded and rotating inside. The connecting bracket 111 has two rotating disks 112 along its length, which respectively mate with the two mating bases 113.
[0028] Reference Figure 2 , Figure 3 In this embodiment, the rotating disk 112 is rotatably disposed in the rotating groove 114. Specifically, the rotating disk 112 is also composed of two parts, which are respectively embedded in the two halves of the mating base 113. The rotating disk 112 has a rotating shaft in the middle, which is rotatably connected to the mating base 113 to achieve the rotation effect.
[0029] Reference Figure 3 , Figure 4 A snap-fit block 120 is provided at the base 113. Specifically, the snap-fit block 120 is provided on one side of the base 113. The snap-fit block 120 is connected to the base 113 by an elastic member. The elastic member is used to make the snap-fit block 120 snap into the rotating disk 112 radially, so as to limit the angle between the rotating disk 112 and the base 113.
[0030] The elastic element is a spring 123. The spring 123 is radially arranged on the mating base 113 along the rotating disk 112. Several limiting grooves 124 are evenly distributed on the periphery of the rotating disk 112. Specifically, in this embodiment, both parts of the rotating disk 112 are provided with limiting grooves 124. The part of the snap-fit block 120 is used to be inserted into the limiting groove 124.
[0031] In this embodiment, the snap-fit block 120 includes a sliding section 121 and a mating section 122. The sliding section 121 is generally cylindrical and passes through the mating base 113. The mating section 122 is located at the end of the sliding section 121 and is a cylinder with a semi-circular cross-section. The arc surface of the mating section 122 is used to engage and abut against the edge of the limiting groove 124. The mating base 113 has a receiving groove (not shown in the figure) radially. The sliding section 121 of the snap-fit block 120 is slidably disposed in the receiving groove. The end of the sliding section 121 away from the mating section 122 passes through the mating base 113, and a limiting piece 125 is provided at this end. An elastic element is sleeved on the sliding section 121, with one end connected to the mating section 122 and the other end connected to the inner wall of the mating base 113.
[0032] In order to avoid the limiting piece 125, the connecting bracket 111 also has a corresponding avoidance notch.
[0033] The sliding section 121 does not extend into the limiting groove 124, and the connection between the mating section 122 and the sliding section 121 is located outside the limiting groove 124. That is, when the rotating disk 112 and the mating base 113 rotate relative to each other, the arc surface of the mating section 122 abuts against the edge of the limiting groove 124. After the arc surface abuts, a force parallel to the sliding section 121 is applied, causing the locking block 120 to move and exit the corresponding limiting groove 124. When it moves into the next limiting groove 124, the spring 123 expands outward, causing the mating section 122 to re-enter the limiting groove 124 to achieve positioning.
[0034] It is worth noting that in this embodiment, among the two mating bases 113 on the same side of the stool 100, only one corresponding snap-fit block 120 needs to be set, and the other does not need to be set. Positioning can be achieved by a limit switch.
[0035] Reference Figure 5 , Figure 6 To increase the firmness of the angle limit, a stop bar 200 is provided on the base 113 and outside the rotating groove 114. Specifically, the stop bar 200 will be set on the other half of the base 113. The stop bar 200 is used to insert into the limiting groove 124 along the rotation axis of the rotating disk 112. The base 113 is provided with a driving component to drive the stop bar 200 to move.
[0036] The driving component includes a connecting post 210 and a driving ring 220 (the thread is not shown in the figure) threaded onto the outer wall of the connecting post 210. The connecting post 210 is fixedly connected to the outer wall of the mating base 113. Specifically, the connecting post 210 faces outward from the seat. A rotating ring 221 is rotatably connected to the end of the driving ring 220, and a stop bar 200 is fixedly disposed on the rotating ring 221. By rotating the driving ring 220, the driving ring 220 will move axially. However, due to the presence of the stop bar 200, the driving ring 220 can only slide axially and is circumferentially limited. At this time, the stop bar 200 can slide and insert into or exit the limiting groove 124. It is worth noting that, in order to avoid the travel of the stop bar 200 interfering with the locking block 120, in this embodiment, the stop bars 200 are evenly distributed circumferentially, but no stop bar 200 is provided at the position corresponding to the locking block 120. In this embodiment, there are six limiting grooves 124 circumferentially, while only five stop bars 200 are provided. Of course, by rotating the two separate parts of the disk 112, the engagement of the locking block 120 and the engagement of the stop bar 200 are relatively independent, so that the two complement each other and thus improve the structural stability.
[0037] To fix the rotation path of the drive ring 220, an abutment piece 222 is provided at the outer end of the connecting post 210. When the drive ring 220 moves outward and abuts against the abutment piece 222, it indicates that the stop bar 200 has completely exited the limiting groove 124, and the rotating disk 112 and the mating base 113 can rotate relative to each other. The mating section 122 can be inserted into multiple limiting grooves 124 in sequence. Since one side of the drive ring 220 faces outward, it is also convenient for the user to adjust.
[0038] In other embodiments, components such as the stop lever 200 and the drive component are not necessarily required. To completely limit the rotation angle, the length of the sliding section 121 can be increased and inserted into the limiting groove 124. Alternatively, the mating section 122 can be omitted. In this case, when the locking block 120 is inserted into the limiting groove 124, the locking block 120 will not retract from the limiting groove 124. In this case, the outer limiting piece 125 needs to be manually pulled to allow the locking block 120 to slide and then retract from the limiting groove 124. This eliminates the need for components such as the stop lever 200 and the drive component, but it may be more cumbersome. The specific structural configuration can be selected according to actual needs.
[0039] Overall, compared to existing technologies, the stool 100 of this application can achieve a multi-angle unfolding state of the armrest 110 after the stool 100 is rotated (e.g., Figure 1 As indicated by the arrow, the angle can be adjusted by either fixing the mating section 122 into the limiting groove 124, or by completely fixing it through the snap block 120 and the stop bar 200, or by completely fixing it through the sliding section 121 inserted into the limiting groove 124. This allows the user to adjust the rotation state of one or both armrests 110 according to actual needs, and also allows the angle of the armrests 110 to be set individually, thus improving the user's comfort.
[0040] Reference Figure 7 Meanwhile, in order to facilitate the adjustment of the drive ring 220, the outer diameter of the contact piece 222 is smaller than the outer diameter of the drive ring 220. In other embodiments, an auxiliary rotating sleeve 230 can be extended from the outer wall of the drive ring 220, so that the auxiliary rotating sleeve 230 extends outward to the operable space, thereby rotating the drive ring 220, avoiding the problem that the drive ring 220 cannot be rotated due to the specific thickness of the stool 100 and the armrest 110.
[0041] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
