Bellow is the detailed description as per the figure:

Refer to FIG. 1 and FIG. 2: This invention involves chair back 1, chair seat 6, front foot 7, rear foot 9 and armrest 3. The bottom end of said back 1 is connected with the rear of the seat 6 with the joining piece 10; there is a movable bolting connection (bolt 2) between the rear end of the armrest 3 and the back 1; the front foot 7 connects seat 6 via bolt 5; the stop piece 11, its one end is turnable in connection with the seat 6 at the middle rear of the seat 6 by a bolt 8, its other end is turnable in connection with the rear foot 9 by a positioning pin; the upper end of the front foot 7 and rear foot 9 is connected with fastener for adjustable armrest positioning 4, the fastener 4 can fit with armrest 3; the said fastener 4 is an integral member with functional parts of positioning embedded joint 14, front foot connecting hole 16, and rear feet connecting slot 17; the said positioning embedded joint 14 can fit with armrest 3; the said connecting hole 16 can fit with the upper end of the front feet 7, and the two are connected with a bolt; the upper end of said rear foot 9 can fit with rear foot connecting slot 17, the two have a movable connection via bolt 13; the fit method between armrest 3 and positioning embedded joint 14 is public-known and unnecessary to give details.

The cross section of the said armrest 3 is of “U” shape; the underside of the armrest 3 has an open 34, and inside the open there is an adjusting slot 31, and inside the adjusting slot 31 there are two limit stops 32 which are parallel to each other to form a travel limit groove 33.

When the positioning embedded joint 14 of the fastener 4 is locked into the corresponding travel limit groove 33 the chair back 1 is fixed a position. The inclination of the chair back 1 can be adjusted in the following way: First pull the front end of the armrest 3 upwards to separate the positioning embedded joint 14 from the travel limit groove 33, then hold the right and left armrest 2 to move the chair back 1 to the required inclination; after that press the armrest 3 onto the positioning embedded joint 14, and permit the positioning embedded 14 to interlock with the adjusted limit groove 33.

In FIG. 3, the front side of said seat 6 can join with extension seat 20 with a joining piece 19; there is a front brace 21 on the said extension seat 20, the two have movable connection by a public-known method.

It is due to such a reasonably designed structure of the upper end of the front foot 7 and rear foot 9 connecting with the fastener for the armrest adjustable-positioning 4 that allows the campstool to be more compact, easier in installation and thus lowers the cost of installation, packing and transportation, and improves its stability and prolong its service life. Besides, this invention has an extension seat 20, which is optional for users so as the campstool can also be used as a deck chair.
