By searching for poles of the unitary scattering amplitudes in the appropriate Riemann sheets, several $1^+$ heavy states are found. In particular, a $D^*K$ bound state with a mass of $2.462\\pm0.010$ GeV which should be associated with the recently observed $D_{s1}(2460)$ state is obtained. In the same way, a $B^*{\\bar K}$ bound state ($B_{s1}$) with mass of $5.778\\pm0.007$ GeV in the bottom sector is predicted.
