| 203 | Ergonomic handle grip for tools | US382694 | 1995-02-02 | US5606772A | 1997-03-04 | Dragan Ilic |
| The present invention features a universal primary hand grip device for use with tools and utensils. The primary hand grip has multiple angles by which the hand can grip the shaft of a tool or utensil, thus making the grip ergonomically efficient. When used in combination with a secondary cross-handle, a tool or utensil can become quite easy to use and comfortable to operate. The primary hand grip device of this invention has a grip that slides over, or is made integral with, the end of the shaft of a tool or utensil. The hand grip has a multiply-angled surface, in which the primary hand can assume a substantially straight-angled position (180.degree. angle) with respect to the axis of the wrist. The correct hand position varies with each tool and with each work surface. The proper grip angle for a particular task allows the hand to maintain a straight angle with respect to the wrist axis, while also imparting the driving force of the arm into the shaft of the tool. | ||||||

| 211 | Shovel-like digging, scooping and transporting apparatus with back-strain relief features | US211063 | 1988-06-20 | US4865372A | 1989-09-12 | Edwin Z. Gabriel |
| This is a compact shovel-like apparatus capable of performing many tasks, including digging, scooping up materials dug, and then enabling one to transport such materials to a chosen site, where the materials would be dumped without straining one's back. The apparatus consists of a removable handle, including bicycle-like handle bars, a round tubular member, and a shovel-head, capable of holding an ample quantity of materials. Runners are an integral part of the shovel-head's underneath to enable one to push the apparatus over suitable terrain, without lifting. For transportation over hard surfaces, like concrete sidewalks and streets, wheels are provided, as an option. In one embodiment the shovel-head is perforated to permit liquids to be discharged, while retaining nonliquid substances. This head's perforated surface may have a resilient plastic overlay to prevent liquids and powdery substances from passing through the holes. In another embodiment the tubular member's angle can be adjusted to suit the user for the particular gardening task to be performed, thus avoiding back strain. With the aid of the plastic overlay, the same basic shovel-head may be used for all of the embodiments. Also a technique is shown for quickly and effortlessly replacing just the toothed strip of the shovel-head. This apparatus being on wheels would enable some physically handicapped persons to do some gardening and similar tasks, including snow shoveling. | ||||||
