Detailed Description

The present invention will be described in further detail with reference to the following detailed description and accompanying drawings:

referring to fig. 1 to 5, a folding chair includes a seat frame 1, a connection unit 2, a first leg 3, and a second leg 4.

The seat frame 1 is the same as or similar to a lunar seat frame in the prior art, is circular or similar, and can be an integral tubular structure or formed by assembling two semicircular tubular structures.

The number of the connecting units 2 is at least two, taking the two connecting units 2 as an example, the two connecting units 2 are respectively installed at two sides of the seat frame 1, as one embodiment, the two connecting units 2 can be symmetrically installed at two sides of the seat frame 1, and the installation manner can adopt a fastening member or a welding manner, as shown in fig. 1 and 2.

The two connecting units 2 are respectively pivoted with corresponding connecting pieces 5, the connecting pieces 5 can be rotatably arranged on the connecting units 2 in a pin shaft mode and the like, sliding grooves 51 are formed in the connecting pieces 5, and the sliding grooves 51 can be designed to penetrate through, as shown in fig. 3.

The first leg 3 comprises two ends, one of which is used as a support, identified as first end 31, which may be U-shaped, which, in the unfolded condition of the seat, is supported on a support surface, on which there are first anti-slip means 32 in contact with the support surface; the other end of the first leg has two ends, which are identified as the second ends 33, and the two ends can be respectively abutted against the corresponding connecting units 2, as one embodiment, the end is detachably assembled with an abutting head 34, the abutting head 34 comprises an abutting notch 341 with a shape matched with that of the connecting unit, as shown in fig. 5, of course, the end of the first leg can be a hollow tubular structure.

In order to integrate the abutting head 34 with the first leg 3, assembling holes are respectively opened on the abutting head 34 and the end of the first leg 3 for installing the abutting head, and the abutting head and the first leg are connected in series through a pin shaft (not shown), and the outer end of the pin shaft is slidably assembled at the sliding groove of the connecting piece 5.

In order to prevent the pin shaft from being separated from the connecting piece 5, a position of the pin shaft penetrating through the sliding groove is provided with a limiting part (not shown in the figure) with the outer diameter larger than the width of the sliding groove.

Of course, the connecting member 5 and the first leg may be connected without a sliding slot, and the first leg is directly rotatably connected to the connecting member 5.

For the second leg 4, it likewise comprises two ends, one of which is used as a support, this end being identified as a third end 41, which may be U-shaped, which, in the unfolded condition of the seat, is supported on a support surface, on which there are several second cleats 42 in contact with the support surface; the other end of the second leg 4 is pivotally connected to the connection unit 2 or the seat frame 1, which end is identified as the fourth end 43, which is pivotally connected to the connection unit 2 for a higher comfort of the user.

As shown, the fourth end 43 of the second leg 4 also includes two ends, and the two ends are respectively pivoted to the corresponding connecting unit 2 or the seat frame 1.

In this embodiment, the first leg 3 and the second leg 4 are both pivotally connected, and as an implementation manner, the upper portion of the first leg 3 is pivotally connected to the middle lower portion of the second leg 4.

The seat frame 1 is provided with a fabric (not shown in the figures), the fabric and the seat frame 1 can be matched by referring to the existing design, and the application only specifically describes the folding structure of the seat.

As shown in fig. 1 and 2, for the unfolding state, the user shape can be limited and supported in this state, and when the folding needs to be performed, the seat frame 1 can be lifted to be close to one end abutted to the first leg 3, so that the connecting unit 2 is separated from the end part of the first leg 3, the end part of the first leg 3 connected with the connecting piece 5 can move along the sliding groove 51 of the connecting piece 5, the connecting piece 5 is combined to rotate, and the lower end of the first leg 3 is drawn close to the lower end direction of the second leg 4 and is directly folded and collected together with the second leg 4 along the direction of the seat frame 1.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
