Abstract: A single-blade razor apparatus and methods for manufacturing the same. A razor apparatus may include a handle and a head pivotably mounted on the handle. The head may include a rear side including an aperture for receiving a single blade, as well as a front side through which a cutting edge of the blade is exposed during use. An upper portion and a lower portion of the head may form the aperture. The lower portion may physically interface with the upper portion so that a front region of the upper portion is physically supported by the lower portion. In a particular implementation, the lower portion may include several protruding latches proximate the front side of the head, which may respectively mate with recesses formed in the upper portion. Alternatively, the latches may be formed in the upper portion and may respectively mate with recesses formed in the lower portion.

Abstract: A shaving blade unit comprising a shaving cartridge having a rearwardly secured shaving blade member wherein the cartridge comprises a) a housing having a front wall, a rear wall, and opposing side walls extending between the front and rear walls; b) a shaving blade member disposed within said walls of the housing and wherein the blade member has a cutting edge that faces a front surface of said housing; c) a resilient member disposed rearward of the shaving blade member and that is secured by a shaving blade member retainer; and wherein the resilient member provides a forward biasing force to the shaving blade member and wherein the shaving blade member exhibits a springing motion during a shaving stroke.

Abstract: A method of manufacturing a razor cartridge by providing a blade unit having a first side wall, a second side wall, and a pair of end walls interconnecting the first side wall and the second side wall. A plurality of blades are secured to the blade unit with a clip positioned at each end of the blade unit adjacent to one of the end walls. Each blade has a blade edge contacting a bottom surface of each of the clips. A frame is provided having a first interior wall and a second interior wall spaced apart from first interior wall that define an opening extending completely through the frame. The blade unit is positioned within the opening of a frame after securing the blades to the blade unit, such that the frame surrounds the blade unit. The blade unit is secured to the frame.

Abstract: A stator includes a substantially cylindrical stator core, which has a fixing ridge provided with a fastening portion for fixing, and which is positioned so that an axial center of the stator extends substantially horizontally; and sealing members, which are respectively attached to both axial ends of the stator core so as to be positioned on a side of the uppermost part of the main body outer peripheral surface with respect to the target ridge, and which respectively form sealing walls that have a height equal to or higher than a horizontal plane extending in the uppermost part of the ridge outer peripheral surface, wherein a recess surrounded by the ridge outer peripheral surface, the main body outer peripheral surface, and the sealing walls serves as a refrigerant reservoir recess for storing a refrigerant.

Abstract: Shaving razors and cartridges intended for mounting on such shaving razors wherein the cartridges include one or mounted solid shaving aid portions that are wing shaped and that exhibit an improved conformation to a shaving consumer's skin surface.

Abstract: There is provided a refuse-trapping cover for a portable working machine, which is capable of reducing the deterioration of the engine-cooling performance of the cooling fan that may be caused by the fibrous sawdust of a palm tree. The refuse-trapping cover includes a frame (40) having a plurality of open windows (40a-40j) and attached to the outer casing (20) of a chain saw (1) to thereby cover the air inlet slits (22), and a mesh member (50) integrally fixed to the frame (40) to thereby cover open windows (40a-40j). The frame (40) is constructed to have predetermined dimension and configuration, and the mesh member (50) is fixed to a predetermined location of the frame (40) to thereby provide a sufficient space (S) between the mesh member (50) and the outer casing (20) to avoid the mesh member (50) from being adsorbed onto the outer casing (20).

Abstract: A detachable razor cartridge has blade seat and at least one blade having a rectilinear cutting edge. An in-line row of integral guard elements project in cantilever position from the blade seat and extend in spaced relation to and beyond the cutting edge of the blade so that the cutting edge of the blade is unobstructed along its entire cutting length. Enlargements at the free ends of the guard elements disposed forward of and in spaced relation to the blade cutting edge may be provided in a variety of configurations and arrangements for smooth skin engagement to control skin flow and limit the degree of blade cutting edge exposure to skin being shaved.

Abstract: The invention relates to a device for setting saw blades or belt-saw blades with clamping jaws arranged on both sides of the saw blade or belt-saw blade and with setting tools arranged on both sides and pivotable about an imaginary axis. It is the object of the invention to put forward a new device with which the setting result may be improved. According to the invention the object is achieved in that in horizontally displaceably mounted guiding blocks arranged on both sides of the saw blade or belt-saw blade there is pivotably mounted in each case a setting tool mounting formed as circle segment, wherein the guiding block is designed simultaneously as a clamping jaw for fixing the saw blade or belt-saw blade, and that displacement devices are provided for the horizontal displacement of the guiding blocks.

Abstract: A one-piece plastic razor molded to contain a handle, a guard plate at the top thereof, at least one locating pin upstanding from the guard plate and adapted to extend through a slot in the razor blade, a cover hinged at one end of the guard plate having at least one slot, beads in the locating pin to frictionally engage the cover slot and firmly lock the cover against the blade on the guard plate and means to ease opening of the cover to replace the blade without sacrificing the locking action of the cover on the guard plate.

Abstract: A safety razor comprising a handle portion, a platform portion molded integrally with the handle portion, and a cap portion molded integrally with the platform portion, a hinge portion interconnecting the platform portion and the cap portion, the cap portion being adapted by flexure of the hinge portion to overlie the platform portion, the cap portion being adapted for connection to the platform portion to securely fasten the cap portion to the platform portion.

Abstract: A safety razor including a platform member and a cap member releasably interengageable to clamp a razor blade therebetween, the cap member having on its undersurface projection means which extend through the platform member and are adapted to be releasably engaged to clamp the said members together. The projection means have a substantial longitudinal extent to provide for distribution of the clamping forces.

Abstract: The invention provides a safety razor comprising a handle, a guard bar adapted to receive a razor blade thereon, and a top cap linked to the guard bar and manually movable into a position in which a razor blade can be trapped between the top cap and the guard bar. A catch secures the top cap on the guard bar, the said catch having a first component on the top cap and a second component which engages with the handle, the first and second components being brought into engagement when the top cap is in the aforesaid position, the handle being movable relative to the guard bar to move the top cap relative to the guard bar for applying a clamping action to a razor blade located therebetween.
