    Abstract: A compact wall-mounted knife holder is formed from a stack of several plates separated by rows of narrow strips of material serving as spacers. The spaces between successive strips form channels for the knife blades. The rows of channels in adjacent pairs of plates crisscross in a lattice pattern but do not interfere with each other since the plates are stacked and each row occupies its own plane. At the same time, knives in all the rows utilize the same space on a wall surface, which makes the knife holder compact. The holder is attached to a wall so that the channels from both sides are at an angle that ensures that the force of gravity holds the knives in the channels. The front plate of the holder can be made from a decorative material and adorned with beatifying design.

  • Patent number: 8347510
    Abstract: A handle assembly for a power tool is disclosed, in which the power tool has a housing, a motor provided in the housing, an output shaft adapted to be caused by the motor to execute reciprocating motion, and a blade assembly (5) extending from the housing along a first axis (A-A). The handle assembly (2) comprises a front handle (6), a rear handle (7) integral with the front handle (6) and a mounting portion adapted to be mounted to the housing of the tool, wherein the rear handle (7) is displaced from the plane (A-A) of the blade assembly (5) in use. As a result of this, the knuckles of the hand of the user that is gripping rear handle (7) are raised away from the surface of the object being cut. This provides the advantage that the user's knuckles avoid any grazing or cutting resulting from contact with the object, or with the ground when carrying out low cutting.

  • Patent number: 8336213
    Abstract: A handle assembly for a power tool is disclosed, in which the power tool has a housing, a motor provided in the housing, and an output shaft adapted to be caused by said motor to actuate a working member extending from the housing along a first axis (A-A). The handle assembly (102) comprises a front handle (106), a rear handle (107) integral with the front handle, and a mounting portion adapted to be mounted to the housing of the tool, wherein the front handle (106) forms an obtuse angle with the axis (A-A) of the working member in use. This last feature makes the power tool more comfortable for a user to operate, provided that the centre of mass of the power tool lies in the region between the front handle (106) and the rear handle (107). This will usually be the case, since the heaviest parts of the tool are generally the working member and the motor housing thereof.

  • Patent number: 8191268
    Abstract: An apparatus for the cutting of tree limbs includes an extensible drive shaft that is detachably-attachable at one end to a portable electric drill and is secured to a housing at an opposite end thereof. The housing converts the rotary motion that is supplied by the drill into reciprocating motion of a saw blade and it disposes the saw blade at an angle with respect to the drive shaft that is slightly less than 90 degrees. An extensible two-part cylindrical outer sleeve covers the drive shaft and is detachably-attached at one end thereof to the drill and at an opposite end to the housing. A hook is provided in the housing and is used to grab and urge severed limbs where desired. An optional clamping mechanism is attached to the housing and is used initially to urge the blade and the limb toward each other during cutting and then to retain the limb proximate the housing after it has been cut for controlled placement and safe release of the limb.
