  • Patent number: 4306373
    Abstract: An improved frictional interconnecting toy block arrangement having a hollow body means fabricated of a semi-flexible material such as a blowmolded plastic. The interconnecting of the toy blocks with each other is achieved by female coupler means and male couplers. The male couplers are part of the body means and unitarily fabricated of blowmolded plastic during the fabrication of the body means. The female coupler means are fabricated of a more rigid plastic such as an injection molded plastic which can be fabricated to close tolerances. The female coupler means fits and is retained within apertures molded into the walls of the body means. Relief means, such as slots, are provided in the female coupler means to allow for dimensional variations of the male couplers that are inherent in the blowmolding process and still provide interlocking with the male couplers.

  • Patent number: 4103451
    Abstract: An articulated toy doll arrangement having a head means, a body means, arm means and leg means, and a neck means interconnecting the head means to the body means, shoulder means interconnecting the arm means to the body means, and hip means interconnecting the leg means to the body means. The mounting of the neck means for interconnecting the head means to the body means is such that at least rotational movement of the head means relative to the body means is provided and, additionally, a nutational movement of the neck means with respect to the body means may also be provided. The arm means is comprised of an upper arm means, a lower arm means and a hand means which may be detachably coupled together for rotational movement about preselected axes. Similarly, the leg means is comprised of an upper leg means, a lower leg means and a foot means which may be detachably coupled together for rotational movement about preselected axes.
