We search for the existence of the weakly bound He-He-K molecules where the binding energies are expected to be of the order of degrees Kelvin. By employing the best empirical interaction between each pair of particles, the Schroedinger equation for the triatomic systems is solved using hyperspherical coordinates in the adiabatic approximation. A bound state is found for each of the {sup 4}He-{sup 4}He-{sup 39}K, {sup 4}He-{sup 3}He-{sup 39}K, and {sup 3}He-{sup 3}He-{sup 39}K trimers, respectively. The bound state for the {sup 3}He-{sup 3}He-{sup 39}K molecule is the halo state found in realistic molecular systems for there are no bound states in both the {sup 3}He-{sup 3}He and {sup 3}He-{sup 39}K dimers.
