The suspension chair frame 100 includes at least two risers 3. A plug assembly structure 2 is connectable with a distal end or top portion of a respective riser 3. As described below, the plug assembly structure 2 may be insertable into a bore of the riser 3 at the distal end of the riser. In the alternative, the plug assembly structure may be sleeved over the riser at the distal end of the riser. In use, the plug assembly structure 2 is connected to the risers in the suspension chair frame, and fixed in position on the risers of the suspension chair frame with the weight of the user sitting in the seat 10. The plug assembly structure 2 increases the effective height or length of the riser 3 in the suspension chair frame 100 to a distance as needed for use; and in collapsing the suspension chair frame 100, a lower end of the plug assembly structure 2 may be detached from the riser 3 and can be conveniently removed, which reduces the effective height of the risers of the suspension chair frame, and further reduces the size of the suspension chair frame for storage, and the overall package size of the product, for instance, for transportation, shipping, and retail shelf space.
In the embodiment shown in the drawings, the plug assembly structure 2 includes two integrally formed tubes 21,22 with different external diameters. One aspect of a specific structure is as follows: the plug assembly structure 2 includes a first tube 21 and a second tube 22. The external diameter of the first tube 21 is greater than that of the second tube 22, and a stepped surface or shoulder 24 is formed at a junction of the first tube 21 and the second tube 22. After the plug assembly structure 2 is inserted into the riser 3, the stepped surface 24 abuts against the top portion of the riser 3. The lower end of the plug assembly structure 2, for instance, the second tube 22, is insertable into a bore of the riser 3 and cooperates with the bore of the riser to constitute an integral body. The lower end of the plug assembly structure 2, for instance, the second tube 22, may be shaped relative to the bore of the riser 3 so that the connection therebetween becomes tighter when in use. The inset of
The external diameter of the first tube 21 may be the same as the external diameter of the riser 3 so as to provide a seamless appearance. The external diameter of the second tube 22 may be slightly smaller than an internal diameter of the riser 3 so as to allow a slip fit when the second tube 22 is inserted into the bore of the riser. As shown in the inset of
The stepped surface 24 of the plug assembly structure 2 may be provided with a protective ring 25, the top portion of the riser 3 may be provided with a sheath 31. After the plug assembly structure 2 is inserted into the riser 3, the protective ring 25 and the sheath 31 may abut against each other. The external diameter of the plug assembly structure 2 is consistent with the external diameter of the riser 3, so as to create a more coordinated and aesthetic appearance. Moreover, adding the protective ring 25 and the sheath 31 at a contact surface between the plug assembly structure 2 and the riser 3 can reduce wear after long-term use and prolong the service life of the product.
In other embodiments, the plug assembly structure 2 can also be a tapered tube with a large upper part and a small lower part, and an outer wall of a lower end of the tube structure of the plug assembly forms conical-surface fit with an inner wall or bore of the riser. The plug assembly structure 2 may also be sleeved over the riser 3.
The respective seat connecting part 1 may be sleeved over the top portions of the plug assembly structure 2. In order to further improve connection strength between the seat connecting parts 1 and the plug assembly structure 2, the seat connecting part 1 may be provided with a through hole 11 in a lower portion thereof. The plug assembly structure 2 may be provided with a through hole 23 in an upper portion thereof. For instance, as shown in the drawings the first tube 21 has the through hole 23. After the seat connecting part 1 is sleeved over the plug assembly structure 2, the seat connecting part 1 may be fixed to the plug assembly structure with a mechanical fastener (e.g., a rivet) 12 passing through the through holes 11,23. The seat connecting part 1 may also be removably connectable to the plug assembly structure 2 with a spring loaded pin arranged in the plug assembly structure 2 that extends through the through hole 11 of the seat connecting part, or a spring loaded pin arranged in lower portion of the seat connecting part 1 that extends through the through hole 23 of the plug assembly structure 2.
In disassembling and folding the suspension chair for storage, the lower ends of the plug assembly structure may be detached from the risers, and if applicable, the tube structure may be removed from the seat connecting part. Then the suspension chair frame may be collapsed together with the pliable seat. Then the pliable seat, the suspension chair frame and the plug assembly structure may be put into an storage bag together. As the effective length of the risers is reduced in size after removal of the plug assembly structures, the overall packaging height is reduced, further reducing an overall volume.
The pliable seat 10 that is connected to left and right seat connecting parts 1 may have straps that are buckled the left and right seat connecting parts to allow adjustment. In the alternative, the seat 10 may have loops with clips that are clipped to the left and right seat connecting parts. The connection of the seat to the seat connecting parts is conventional. The suspension chair pliable seat is at least partially located between the left and right risers 3, wherein the risers 3 are each provided with a sliding part 4, and are further provided with a bottom connecting part 5 at a bottom portion or proximal end of the risers 3. The two risers are connected to each other by cross tube assemblies 6 which are respectively hinged with the sliding parts 4 and the bottom connecting parts 5. The risers 3 are each provided with a diagonal supporting assembly respectively on front and rear sides thereof.
The diagonal supporting assembly includes a diagonal supporting rod 7, a bottom supporting rod 8 and a foot supporting block 9, wherein one end of the diagonal supporting rod 7 is hinged with the sliding part 4, one end of the bottom supporting rod 8 is hinged with the bottom connecting part 5, and the other ends of the bottom supporting rod 8 and the diagonal supporting rod 7 are connected to the foot supporting block 9.
Although the embodiments of the present utility model have been shown and described in the above, it can be understood that the above embodiments are exemplary and shall not be construed as limitation to the present utility model. Those of ordinary skill in the art could make changes, amendments, substitutions and variations to the above embodiments within the scope of the present utility model without departing from the principle and purposes of the present utility model. Any simple amendments, equivalent changes and modifications made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the technical solutions of the present utility model.
