In this embodiment, there may be two sliding tubes 92, and each sliding tube 92 is individually connected to one leg rest assembly 1. The two leg rest assemblies 1 have the same structure and are arranged in a left-right symmetrical mode.
As shown in fig. 2, each leg rest assembly 1 includes a fixed seat 3, the fixed seat 3 is fixedly connected to the sliding tube 92, and the fixed seat 3 can be regarded as a stationary part during the movement of the single plate 5 described below.
As shown in fig. 3 and 4, in the process of turning, the parts that are turned are three parts, namely the spacer 2, the single plate 5 and the swing seat 4, and the fixed seat 3 is not turned. Specifically, the swing seat 4 includes a connecting seat 41 and a rotation post 42. The connecting seat 41 is used for connecting the single plate 5, and the rotating column 42 is the rotating shaft of the turning action. The side of fixing base 3 has seted up mating holes one, rotates post 42 card and goes into mating holes one to relative rotation takes place under user's operation, thereby drives whole upset action.
In the scheme, a turnover design of synchronous turnover and middle section reinforcement is adopted. In particular, there is a connecting piece 6, in this embodiment a polygonal shaft, for example a hexagonal shaft, is used. As shown in fig. 3, a hexagonal shaft passes through two swing seats 4, through two fixed seats 3, and through a spacer 2, and the hole of the fixed seat 3 may not be matched with the hexagonal shaft, for example, the size of the hole is larger than that of the hexagonal shaft, and no rotation transmission occurs between the two. While the openings of the two oscillating supports 4 and of the spacer 2 are adapted to the hexagonal shaft in terms of size and shape, so that there is a rotational drive between these several components. When a user operates one single board 5 to turn over, the user naturally drives the other single board 5 to turn over synchronously. And in the middle section, a spacer bush 2 is additionally arranged, the spacer bush 2 comprises a main cylinder 21, and an auxiliary column 22 extends out of the left end and the right end of the main cylinder. And the fixed seat 3 is provided with a second matching hole, the auxiliary column 22 is clamped into the second matching hole, so that in the overturning action, the two auxiliary columns 22 in the middle position and the two rotating columns 42 at the two side positions jointly serve as rotating shafts of the overturning action, and due to the existence of the hexagonal shaft, the four components can keep good coaxiality, the overturning action is simple and smooth, and the stability is high.
The spacer bush 2 has two functions, namely the synchronous overturning and middle section strengthening function, and the stability of the whole structure is strengthened to avoid deformation. Specifically, the slide tube 92 has a certain length. One end of which is connected to the seat 91, and the position of the end can be regarded as fixed and reliable. And the other end is connected with the leg rest assembly 1, in practical use, the two leg rest assemblies 1 are possibly close to each other due to the action of the feet of the user. This proximity may cause the sliding tube 92 to tilt and bend, which may be detrimental to the useful life of the device over time. And the spacer 2 is positioned between the two fixed seats 3, and the sliding tube 92 is fixedly connected with the fixed seats 3, so that the distance between the tail ends of the two sliding tubes 92 is limited, and the sliding tubes 92 are not bent due to mutual approaching.
In addition, in the process, the turning angle of the veneer 5 is designed to be limited. In particular, there is at least one fixing plane 61 on the connecting piece 6, and in this embodiment, there are six fixing planes 61 due to the hexagonal axis. The fixing piece surface 61 is provided with a limit bolt 7. As shown in fig. 4, the position of the limiting bolt 7 is located in the inner cavity of the fixing base 3, two abutting flaps (not shown in the figure) are arranged in the inner cavity of the fixing base 3, and the limiting bolt will abut against the abutting flaps in the turning process, so that the turning angle of the veneer 5 is limited in two ranges. In practical application, the two limiting angles can be the angle of the veneer 5 in the using process and the angle in the storage state.
In the scheme, two sets of leg rest assemblies 1 are adopted, so that two limit bolts 7 are arranged. The existence of the fixing plane 61 makes the installation process of the limit bolts 7 easier on the one hand, and makes the installation angles of the two limit bolts 7 more accurate and controllable on the other hand, so that the limit angles of the two fixing seats 3 to the two limit bolts 7 are consistent and stable.
As shown in fig. 3 and 4, the swing seat 4 comprises a connecting seat 41, which connecting seat 41 is connected to the single plate 5 as a connecting medium on the one hand and also to the connecting piece 6 on the other hand. Specifically, the connecting seat 41 is connected to the connecting member 6 by a fixing bolt 8. The connecting seat 41 and the spacer 2 are tightly attached to the fixing seat 3 left and right, so that the sliding tube 92 is not easy to tilt inwards or outwards.
The single board 5 adopts a design scheme of "two parts and three layers", specifically, as shown in fig. 5, the single board 5 includes two parts, namely a base box 51 and a sliding plate 52. The base case 51 and the link base 41 are connected to each other with relative sliding in the seat width direction therebetween, and in this sliding motion, it can be regarded as a stationary member. The sliding plate 52 and the base case 51 slide relatively, and in the sliding motion, they are regarded as a moving member, and are main components on which the feet of the user rest. The base box 51 is designed in two layers, including an upper box and a lower box, and the sliding plate 52 is arranged between the upper box and the lower box. The three-layer design not only can ensure that the sliding of the sliding plate 52 is more smooth and stable, but also ensures that the sliding plate 52 has better supporting stability as a main bearing part.
The upper box and the lower box are connected by a connecting column, and a sliding groove 523 matched with the sliding plate 52 is arranged in the sliding plate 52. When the user slides the slide plate 52, the connection pole moves in the slide groove 523. The position of the sliding process is fixed by the insert. Specifically, the insert comprises an elastic member and a top bead, the elastic member having one end mounted on the base case 51 and one end connected to the top bead. The sliding plate 52 includes an adjusting bar 521, which has a plurality of engaging holes 522 at different positions. The elastic member applies an ejecting elastic force to the top bead, a portion of which is caught on the base case 51 and a portion of which is caught in the fitting hole 522, thereby completing the relative fixation of the slide plate 52 and the base case 51. When the sliding plate 52 needs to slide out, the user only needs to apply a slight force to overcome the elastic force of the elastic member and retract the top bead, so that the relative sliding can be realized, and the retraction can be smooth due to the spherical arc design of the top bead.
