DRY SHAVER GUARD AND HAIR TRIMMER ATTACHMENT Filed Jan. 14, 1964 INVENTOR Sam A. Madrid U MMW ATTORNEY r k l United. States Patent Ofiice 3,178,815 Patented Apr. 20, 1965 3,178,815 DRY SHAVER GUARD AND HAIR TRIMMER ATTACHMENT Sam A. Madrid, 631 OFarrell St., San Francisco, Calif. Filed Jan. 14, 1964, Ser. No. 337,601 2 Claims. (Cl. 30-90) This invention relates to a dry shaver guard and hair trimmer attachment, and has for an object to provide a hair trimmer attachment, a hair trimmer attachment which may be attached to a dry shaver in the same manner that the cutter guard is usually attached, and which, when attached, may be used for trimming ones own hair, for keeping the hairline trimmed after a visit to the barber and thus extend the time between barber visits.
A further object of this invention is to provide a hair trimmer attachment which may be made from the conventional shaver protective guard and which may thereafter be used alternatively as a protective guard and as a hair trimmer attachment for trimming the hair line of the side burns, the nape of the neck, behind the ears, and elsewhere.
A further object of this invention is to provide a plurality of appropriately positioned slots in a dry shaver protective guard whereby the hair can be trimmed by the dry shaver with the slotted guard in place on the shaver, the width of the slots and the thickness of the material of the guard limiting the length of the cut hair.
A further object of this invention is to provide a hair trimmer guard attachment for a dry shaver, wherein the guard is provided with a plurality of narrow, parallel slots extending to one edge of the bight of the guard, a triangular slot at each end of the parallel narrow slots, and a pair of approximately square slots extending to the pposite edge of the bight of the guard, the guard being substantially U-shaped in the customary manner.
The essence of this invention is in providing the conventional guard for the dry shaver with the appropriately positioned slots therein so that the dry shaver, with the hair trimming attachment held thereon in the same conventional manner as the guard is held thereon, may be used for trimming the hair line at the nape of the neck and behind the ears and between barber visits to thus lengthen the time between visits to the barber.
A further object of this invention is to provide an attachment for a dry shaver that will enable the user to trim his own hair accurately and conveniently, with special attention to the hair line at the nape of his neck and at the ears and sides in front of the ears.
With the above and related objects in view, this invention consists in the details of construction and combination of parts, as will be more fully understood from the following description, when read in conjunction with the accompanying drawings, in which:
In brief, this invention consists of a conventional dry shaver guard of general U-shape having a wide bight for extending over the shaver blades and short legs extending over the ends of the shaver, with the usual abutments for detachably holding the guard on the shaver, wherein a plurality of slots with parallel side walls are provided in the bight extending from an unslotted mid area to the leg area, the slots having parallel side walls, the slots along one leg being two generally square slots, with two of the sides of each slot generally parallel to two of the sides of the other square slot, the slot along the other leg being two series of elongated, generally parallel spaced apart slots, and at each outside end an angular slot is provided with two sides, one along the U-leg and the other at an acute angle from the U-leg to the outside edge of the guard, to thus provide a maximum of adaptability in cutting hair on different parts of the head.
FIG. 1 is a perspective view of the hair trimmer attachment of this invention, as applied to a conventional Remington electric dry shaver.
FIG. 2 is an elevational view of the attachment per se.
FIG. 3 is a sectional view on line 3-3 of FIG. 2.
FIG. 4- is a sectional view on line 4-4- of FIG. 2.
There is shown at 10 the hair trimmer of this invention as applied, in FIG. 1, to a conventional dry shaver 11, the dry shaver 11 shown being a conventional electric Remington dry shaver, but it will be understood that this invention can be applied on any conventional dry shaver of this general type, of which there are quite a number on the market, both of the electric and the mechanical or hand powered type, wherein a protective guard, usually of plastic, and usually substantially U-shaped in cross section, with a long bight, complementary to the shaver surface 14 of the dry shaver 11, and short legs 18 at each side provided with attaching lugs 22 cooperating with complementary lugs on the dry shaver.
The dry shaver guard 10 is customarily substantially U-shaped, with the bight 12 of the guard 10 being complementary to the shaver surface 14. Extending from opposite sides 16 and 17 of the bight 12 are the conventional U-legs 18 complementary to the sides 29 of the shaver cutters, and provided as usual with a lug 22 at its center cooperating with a complementary lug on the dry shaver for holding the guard in protective position over the shaver surface to protect the shaver cutters therebelow. The guard It is usually about V inch in thickness.
The guard 10 as thus far described is conventional with substantially all dry shavers now on the market. In this invention, the guard is provided with a selected number of openings therethrough in the form of variously located slots and openings, so that the hair may extend through such slots and openings and be cut by the shaver cutters below the shaver surface 14. A group of parallel spaced apart slots 24, in two spaced apart series, separated by a wide strip 26, with each slot separated from its adjacent slot by a narrow strip 28 extends from one side 16 of bight 12, the slots 24 being approximately twice as wide as the narrow strips 28 therebetween. Also, extending from this same side 16 at each end of the bight 12 is a right angle triangular slot or recess 30 having one base leg extending along the side 16 of the bight 12, the other base leg coinciding with the end edge of the bight 12, and the hypotenuse leg extending inwardly about inch from the end edge to the end of the base leg along the side of the bight. The slots 24 and the triangular recess extend toward a midsection 32 extending across the middle of the bight 12.
On the side 17 of the bight 12, there are two spaced apart somewhat square recesses 34, separated from each other by a strip 36 about as wide, more or less, as the width of the somewhat square slots or openings 34, each square recess or slot having two sides generally parallel with two of the sides of the other square.
In operation, the hair trimmer attachment may also serve in the place of the regular protective guard, or may be substituted for the regular protective guard only when it is desired to trim ones own hair. In the average case, the guard 10 is usually about inch thick, the slots 24 are about A; inch wide, with the narrow strips 28 from A to 10, inch. The square slots or recesses 34 are about /2 inch by /2 inch, and are located about inch from each edge. The base legs of the triangular recesses extend about A inch from the edge of the guard. These dimensions given are examples only, for the exact sizes will vary from make to make of dry shaver, the dimensions given being those preferred with a Remington type of dry shaver.
back of the ears to trim the hairline. For thenape of the neck and where the hairline is to be feather-edged closely, the side of the attachment with the two large.
square generally parallel slots or openings 34 is used as this permits the skin at the large slots to rise slightly and permits the cutters to be closer so that the hair is trimmed shorter. Elsewhere, the narrow slots 24 permitting the hair to be cut somewhat longer, are used.
By using this hair trimmer attachment, regularly, at least once a week, starting immediately after a visit to the barber, it will be found that the hair can be kept looking very neat, and the intervals between visits to the barber can be greatly lengthened. 7
Although this invention has been described in considerable detail, such description is intended as being illustrative rather than limiting, since the invention may be variously embodied, and the scope of the invention is to be determined as claimed.
Having thus set forth and disclosed the nature of this invention, what is claimed is:
1. A dry shaver guard and hair trimmer attachment comprising a somewhat U-shaped guard complementary to the shaver surface and opposite sides of a dry shaver, the bight of said ueshaped guard fitting snugly against the cutter heads of the dry shaver, the legs of the U-shaped guard fitting against the opposite sides of the assembled cutter heads, the legs having means detachably securing the guard to the dry'shaver; the bight of said U-guard having an unslotted mid area extending transversely thereof from one side edge to the opposite side edge, and a series 1 of slots on each side of said mid area, the side edges of said slots extending generally parallel to each other between said unslotted mid area and a juncture with the U-guard leg, the series of slots on one side ofsaid unslotted mid area consisting of two generally square slots, the series of slots on the other side of said unslotted mid area including two pluralities of elongated slots, the width 4 of said elongate slots being approximately twice that of the interveningwalls, and a still wider wall separating one plurality of elongate slots from the otherv plurality of elongate slots, said generally square slots permitting close trim of the hair line at the nape of the neck, the elongate vslots providing for somewhat longer hair cutting on the head.
