Abstract
The present invention is directed to a razor unit having a member comprising a top frame with an integral weight. The portion of the member which acts as the integral weight is contained within the hollow shell of a razor handle while the top frame portion protrudes beyond one end of the handle to provide a decorative cover for a razor cartridge or an attachment means for a razor cartridge. The integral member reduces the overall number of parts of the razor, reduces the assembly time and provides a stiffening member to the razor handle. Further, the integral member provides proper weight and balance to aid in obtaining a comfortable shave.
Description
RAZOR FRAME WITH INTEGRAL WEIGHT
Background of the Invention 1. Field of the Invention to This invention relates to wet shave razors and, in particular, to wet shave razors having a die cast top frame with an integral weight and stiffener.
Background of the Invention 1. Field of the Invention to This invention relates to wet shave razors and, in particular, to wet shave razors having a die cast top frame with an integral weight and stiffener.
2. Description of Related Art Most commercially available wet shave razors consist of at least five separate components. These components include the razor head which, in the case of a permanent system is used to attach a razor cartridge and in the case of a disposable system includes the cartridge, two half shells of the handle, a weight, and a top frame which covers the razor 2o head. During manufacturing, the two half shells are fitted together surrounding the weight and the top frame is placed such that it covers the razor head. The end result is a razor unit which requires a maximum number of parts and significant assembly, resulting in greater difficulty and expense to the razor manufacturer.
It would be advantageous to provide a razor assembly with a minimum of parts by integrating the top frame with the weight. The result would be to minimize the time and expense required to assemble the razor unit.
Summary of the Invention The present invention is directed to a razor unit having a member comprising a top frame with an integral weight. The portion of the member which acts as the integral weight is contained within the hollow shell of a razor handle while the top frame portion protrudes beyond one end of the handle to provide a decorative cover for a razor cartridge or an attachment means for a razor cartridge. The integral member reduces the overall number of parts of the razor, reduces the assembly time and provides a stiffening member to the razor handle. Further, the integral member provides proper weight and balance to aid in obtaining a comfortable shave.
Brief Description of the Drawings Figure 1 is an exploded view of a razor unit containing the top frame with the integral member.
Figure 2 is a cut-away top view of a razor unit containing the top frame with the integral member.
Figure 3 is a side cut-away view along line A-A of Figure 2.
2o Detailed Description of the Preferred Embodiments Reference will now be made to the presently preferred embodiments of the invention. For the purpose of this application, wet shave razors are defined to be razors which are customarily utilized in conjunction with soap or shaving cream and hot water.
The definition of wet shave razors includes both disposable razors, in which the user discards the entire unit after a certain number of uses, and permanent systems, with which the user discards and replaces the razor cartridge after a certain number of uses. In both instances, the razor head, or cartridge, is the portion which surrounds and contains the blade or blades. The combination of the razor head and the handle, either permanent or 3o disposable, is defined as the razor system.
The present invention provides for a wet shave razor system which comprises a razor handle consisting of an upper shell and a lower shell and a top frame having an integral weight member. As illustrated in Figures 1 - 3, top shell 15 and bottom shell 16 surround the integral weight member 10 in the razor system. In an alternative embodiment, the razor handle may be a hollow, one-piece unit which surrounds the integral weight member. The integral weight member 10 comprises interior weight section 11 which is contained within the handle, transition section 13 (surrounded by the circle in Figures 1 and 2) which protrudes through opening 21 in the top shell and top frame 12 which extends externally beyond the end of the top shell. In the preferred embodiment illustrated, the top frame 12 1o comprises a decorative cover for razor attachment mechanism 17, 17A which is affixed to the end of bottom shell 16; cap 18 is optionally placed on the top frame.
Attachment means are provided on the top and bottom shells to allow the two shells to be tightly and permanently attached to each other. In the illustrated embodiment, snaps 19 protrude from the top shell and fit into grooves 20 in the bottom shell. In the preferred embodiment, the 15 integral weight member 10 contains snap feature 14 which allows the integral weight member to be directly affixed to either or both of the top and bottom shells.
In addition to providing a weight, the integral weight member 10 also acts as a stiffener in order provide strength to and stiffen the handle so that the handle will not break 20 or overtly bend in response to forces encountered during shaving. While the integral weight member 10 may be formed from any suitable material, preferably the integral weight member is formed from a die cast material. Preferable materials for the weight member include high density plastics with a specific gravity greater than 2, zinc diecast, aluminum diecast, magnesium diecast, stainless steels, copper alloys and powdered metals. The 25 weight of the weight member may vary as desired in order to provide the proper balance and "feel" to the razor handle so that the razor provides a comfortable shave.
Preferably, the weight of the weight is in the range of about seven grams to about sixty grams, with a preferred weight of about thirty-five grams.
As set forth above, the integral weight member is preferably manufactured via a die 30 casting process. During assembly of the razor system, the integral weight member is inserted into the razor handle, either between the two shells or within the hollow one-piece handle. In the event that two shells are utilized, the shells are permanently snapped together following the insertion of the integral weight member. Additionally, the integral weight member is also snapped to the either or both of the top and bottom shells.
Simultaneously, the top frame portion is placed over and affixed to the razor attachment mechanism.
While there have been described what are presently believed to be the preferred embodiments of the present invention, those skilled in the art will realize that various changes and modifications may be made to the invention without departing from the spirit of the invention, and it is intended to claim all such changes and modifications as fall within l0 the scope of the invention.
It would be advantageous to provide a razor assembly with a minimum of parts by integrating the top frame with the weight. The result would be to minimize the time and expense required to assemble the razor unit.
