  • Patent number: 5390944
    Abstract: An implement carrier and organizer is provided, including a hollow body with a top closure from which are suspended upwardly opening wells for storage of tools inverted with the handles downward within such wells. Both deeper wells for long handled tools, and more shallow welts for short handled tools, are provided. Casters are attached to the bottom of the carrier and organizer so that it may be easily trundled from one place to another, and rotated when in cramped storage space areas for easy access to particular tools.

  • Patent number: 4196921
    Abstract: An improvement for cross-country ski bindings comprising apparatus for preventing or limiting lateral motion of a cross-country ski boot with respect to the ski when the boot is lowered into close proximity with the upper surface with the ski. The apparatus may comprise two pivotal vertically upstanding members between which the ski boot fits, the upstanding members being biased apart from each other so that the boot enters freely therebetween, the weight of the skier then, applied through the sole of the boot, causing the vertical members to move closer together to grip the boot in its general central, instep, portion. Thus the boot is firmly held in a central location on the ski. When, during use of the ski, it is desired to raise the boot, the vertical members are biased outwardly to release the boot.
