When they are engaged and brought into close contact with each other, the engagement-protruding piece and the engagement concave portion are positioned and oriented properly as viewed in a width direction thereof. Thus, the blade member and the finger ring member can be stably assembled in a separable manner.

  • Patent number: 7536791
    Abstract: A work tool according to the invention is configured in such a manner that when an operator performs a predetermined operation by gripping a gripping section and opening/closing an active section, the opening and closing operation can be achieved smoothly without employing a spring by gripping the gripping section strongly and releasing the same because a repulsive force of magnets urges two pressure-nipping members in the direction in which the gripping section opens.

  • Patent number: 7497016
    Abstract: A pair of gardening shears include a main body, two shanks, two positioning blocks, two handles, and two handle jackets. Thus, each of the two handles is retracted inwardly onto and fully expanded outwardly from the main body to adjust the distance between the main body and each of the two handles, thereby facilitating the user operating the gardening shears in an energy-saving manner. In addition, each of the two handles is substantially arc-shaped and is bent outwardly to provide a comfortable sensation to the user, thereby facilitating the user holding the gardening shears. Further, each of the two handles is exactly locked onto the main body by the locking member without incurring slip, thereby facilitating the user holding and operating the gardening shears.

  • Publication number: 20090000127
    Abstract: Multi-purpose shears adapted to include structure that enables rapid and effective cutting of sheet fabric as well as tough fabric. A U-shaped housing is positioned on a loop grip of the shears, the housing having an insertion slot defining an opening at one end and at least one blade having a cutting edge mounted within the housing. The blades are positioned within the housing so as to present a cutting edge obliquely to the insertion slot, so as to cut or slice material inserted into the insertion slot. The insertion slot is generally configured in a direction that permits ergonomic handling of the shears for both snipping and for slicing. The opening may be oriented in a proximal direction relative to the operator, so that the operator may snip in one direction and slice in the reverse direction.

    Abstract: An ergonomic handle for use with a hand tool, such as a pair of scissors or the like, is disclosed which includes first and second opposing lever members coupled together at a pivot point to permit reciprocating movement of the lever members between a closed position and an open position. The lever members may include a cutting blade or other tool feature on a first end adjacent the pivot point, and a handle on a second end adjacent the pivot point opposite the first end. The fixed handle has a loop portion which includes an inner surface and an outer surface along one side of which abuts a corresponding outer surface of the opposing lever member while in the closed position. Each loop portion is made from a rigid material segment and a resilient material segment, with the rigid material segment having a cavity open at the outer loop surface and the resilient material segment extending across the cavity at the inner loop surface.
