The weak decay as well as the strong nucleon coupling constants of the
isoscalar axial vector meson $f_1 (1285)$ are estimated within the octet quark
model. It is shown that the empirical value for the coupling of $\overline{s}s$
quarkonium to nucleons can be understood by attributing the $f_1(1285)$-nucleon
coupling to the $a_0\pi N$ triangle diagram.
