  • Patent number: 7100285
    Abstract: A self-opening handle for a heavy duty artistic knife includes a handle which is combined with a pair of corresponding halves and rotatably connected on their rear ends, a blade rack slidably disposed in the front portion, a blade chamber formed in the rear portion and a swivel lock locking the lower middle portion thereof. The feature is that a magnet disposes in a lower inner wall of each of the corresponding halves with the identical pole toward each other so that when the swivel lock is at a unlocking position, the pair of corresponding halves will automatically open a large angle due to the expelling force of the magnets. Therefore providing a convenient and swift changing of the blade from the blade rack.

  • Patent number: 7010859
    Abstract: The disposable cutting head is basically a four element clip together assembly with a base, lower and upper cutting blades, and spring. The base serves as the support for the entire assembly and incorporates the attachment elements for retention to a clipper. The spring holds the elements together, forces the cutting blades together and includes the runner under which the upper blade slides. The entire assembly is such that the head assembly with blades is of the disposable type, but uses metal blades. If desired the blades alone may be disposed and the head assembly reused; however, the structure is not intended for long wear and use. The head and blades are constructed such that the common problems encountered with existing removable/disposable heads and blades as for example heat retention in the blades and head and the catching and pulling of hair are minimized. Use with clipper comb elements is also accommodated.

  • Patent number: 7010860
    Abstract: A cutting device is operable with one hand for cutting a circle or an elliptical shape in a sheet of material. In a first embodiment for cutting elliptical shapes, the cutting device includes a first member for placement on the sheet material and a second member for simultaneous pivotal and translatable movement with respect to the base plate. The first member has a first pivot point that is movable along a first axis, while the second member has a second pivot point that is movable along a second axis substantially perpendicular to the first axis. The first and second members are operably connected to each other at the first and second pivot points. A knob is connected to one of the pivot points and is sized to be grasped by one hand and rotated. Rotation of the knob about the one pivot point causes the second member to rotate and slide in an elliptical pattern with respect to the base plate.

  • Patent number: 7003888
    Abstract: A saw blade clamping arrangement for a power tool includes a clamp support, a biasing member and an actuation member. The clamp support is interconnected with the drive shaft for reciprocating motion with the drive shaft relative to a housing of the power tool. The clamp support is configured to selectively receive a saw blade of the power tool in various orientations. A release lever is carried by the housing and is manually rotated to move a control member between a first position in which the saw blade is coupled to the drive shaft and a second position in which the saw blade may be displaced from the drive shaft. In at least one of the orientations, the saw blade is positioned offset from the drive shaft and proximate one of the side walls of the tool housing to allow for flush cutting of a work piece.

  • Patent number: 6983542
    Abstract: A plastic cutlery item, fabricated primarily from a plastic material, such as polystyrene, having a metallic coating that imparts to this cutlery item the appearance of metal cutlery or silverware. The plastic cutlery or tableware items are molded using traditional injection molding techniques, and subjected to a vacuum metallizing process in an individualized non-contiguous manner, where a thin metallic layer is deposited on at least one of their surfaces. The resultant items simulate the appearance of solid metal cutlery or tableware. In the most preferred embodiment of the invention the plastic cutlery or tableware items are molded from a light-transmitting grade of Polystyrene resin and are coated with a thin stainless steel layer through vacuum sputtering deposition on only one of the surfaces.

  • Patent number: 6973727
    Abstract: An electric driving scissors provide a high torsion force. The electric driving scissors includes a casing, a motor, a driving disk, a crank, and a cutting unit with a pair of knives. The driving disk, crank and knives of the cutting unit are connected pivotally and eccentrically. The motor is installed with a speed change means so that the rotation speed of the motor can be reduced to a lower speed in the rotary shaft with a higher torsion force. Thereby, a hard object can be cut. Furthermore, by the eccentric hole of the driving disk, the axial hole and pivotal hole at two ends of the crank, the rotary shaft of the motor can rotate, while the crank move linearly. Thereby, the angle of the movable knife of the cutting unit is changeable.

  • Patent number: 6973730
    Abstract: A razor includes a handle, a flexible neck extending from the top of the handle and a blade-carrying razor head pivotally fitted on the distal end portion of the neck. A lower portion of the handle functions as an actuator for dispensing shaving material contained within the handle and is operable between a stop position and a dispensing position. The neck is structured to flex and/or twist in a yielding action in response to external forces as the blade-carrying razor head travels over irregular or varying contours of the skin surface. The flexible neck may be formed to include a scoop for directing a stream of water through the blade-carrying razor head in a fanned array, providing an enhanced flushing action to remove debris and residue which accumulates on the blades.

  • Patent number: 6964097
    Abstract: The present invention is a shaving apparatus that includes a razor cartridge having one or more razor blades, a housing, a flexible bladder, and a handle having an interior cavity and an actuator. The housing includes an exterior surface that is adjacent the razor cartridge and includes one or more ports. The housing is attached to an open end of the flexible bladder such that the one or more ports are in fluid communication with the contents of the flexible bladder. The flexible bladder stores a flowable shaving aid material and is disposed within an interior cavity in the handle. The actuator is operable to collapse the flexible bladder, thereby forcing the flowable shaving aid material from the flexible bladder to the one or more ports. Once the flowable shaving aid material exits the ports, it is dispensed on the surface being shaved adjacent the razor cartridge.

  • Patent number: 6959496
    Abstract: A barbeque fork comprises a base or handle, tines, biasing rod, at least one guide for supporting and sliding the rod and a cross-brace or bracket, wherein the rod is supported over and along the top surface of the handle by preferably two guides, the guides projecting outward from the handle and each defining apertures for receiving and guiding the rod when sliding it over the handle. One end of the rod is terminated by a stop or cap that prevents the rod from passing completely through the guides. The cross-brace is diametrically positioned at the opposite end of the rod and engages the food items when the rod is slid forward to support or remove the food items. In an alternative embodiment, the barbeque fork includes a thermometer device for reading the temperature of food items.

  • Patent number: RE39286
    Abstract: A cutting device especially designed for cutting up salad greens includes two blades, a rib and handles. The two blades are inter-secured to rotate together about a common axis, but are spaced apart from each other along the common axis. The rib is pivotably secured to the two blades so as to rotate about the common axis, and is curved in a direction of rotation so as to have a concave surface. The handles are integrated with the two blades and the rib to control the two blades and the rib to rotate simultaneously between open and closed positions. The concave surface of the rib is the lead surface when moving from the open position to the closed position, and the cutting edges of the two blades cross edges of the concave surface when moving from the open position to the closed position, so as to perform a cutting action.
