  • Patent number: 4915400
    Abstract: A snowboard toy is disclosed having an improved safety release foot harness. The toy has a semi-rigid ski platform having an upturned front end and a main body portion extending rearwardly from the front end. A number of strap retainers are located on the main body portion with one strap retainer located towards the rear of the main body portion and one located towards the front. The strap is secured at one end and has a free end passing through the strap retainers. The strap forms foot retaining loops and when the snowboard toy is in use the strap is pulled on the free end to create tension to secure a person's feet to the snowboard toy beneath the strap. Upon release of the tension in the strap the feet are also released.
