A crossbar 23 is fixedly mounted between the two positioning members 30 and 40. A reclining brace 21 substantially U-shaped in section includes two vertical posts 212 each pivotally engaged with a mediate portion of the backrest 20 and each having an adjusting member 22 formed thereon. The adjusting member 22 has a plurality of notches 222 defined therein for being detachably engaged with the crossbar 23.
In assembly, referring to FIGS. 1-2 with reference to FIGS. 3-5, the inner sleeves 311-341 and 411-441 are respectively fitted around the associated legs 132-162 and 134-164 of the supporting members 13-16. The horizontal portions 184, 194 of the L-shaped members 18, 19 are fitted in the supporting member 17 respectively and the inner sleeves 351, 451 are fitted around the vertical portions 182, 192 of the L-shaped members 18, 19 respectively.
The positioning members 30, 40 are then attached to the body 10 with the outer sleeves 31-35 and 41-45 thereof being fitted around the associated inner sleeves 311-351 and 411-451.
Then, the positioning nuts 71-75 and 81-85 are threadedly mounted around the outer threads 131-161, 181, and 133-163, 191 respectively, thereby positioning the supporting members 13-17 by means of the two positioning members 30, 40 and the positioning nuts 71-75 and 81-85.
The backrest 20 is subsequently pivotally attached to the body 10 and the crossbar 23 is fitted between the two positioning members 30, 40. The reclining brace 21 is pivotally attached to the backrest 20 with the two adjusting members 22 resting on the crossbar 23, thereby easily adjusting the tilting level of the backrest 20 by means of detachable engagement between the plurality of notches 222 of the adjusting members 22 and the crossbar 23.
Finally, the two wheels 50, 60 are rotatably mounted on the two positioning members 30, 40 respectively, thereby accomplishing the assembling of the deck chair assembly.
