` l.'7. Claims.

This invention relates to shavers and particularly to a guard for protecting the shaving head or heads thereon.

The invention comprehends the provision of a guard for a shaver head arranged for detachable mounting on the shaver case to be normally supported in spaced relation over the heads on shavers in such a way that in case the end carrying the shaver head or heads is accidentally engaged with another object, the guard will receive the force of impact.

The invention comprehends the provision of a guard for the heads of shavers having interengaging parts on the case of the shaver and the guard so that flexing of the guardfwill engage and disengage the parts in cletachably mounting the guard on the shaver in position to protect the shaver heads from damage by impact with other objects.

The invention comprehends a guard for shavers having a head protecting section and side sections extending from opposite sides thereof in substantially parallel relation formed with parts `for cooperative engagement with parts on the casing of the shaver to detachably secure the guard in position on the shaver to guard the head or heads thereon, the structure being flexible so that the parts may be engaged and disengaged in a convenient manner for detaching and applying the guard to the shaver. l

'I'he invention comprehends the provision of a guard wherein side sections extending from the head protecting section are formed at opposite ends with laterally extending protecting flanges that simulate thickness at the sides of the shaver and provide for the transmission of shock applied to theguard at the sides and corner portions direct to the casing through the flanges as well as provide a thickness simulating structure at the ends of the guard so that it may be more readily engaged for manual attachment and removal from the shaver.

The guard of this invention further comprehends the provision of a head protecting section particularly adapted for use with multiple head shavers wherein a series of separate sections may be provided so that one will cover and protect each shaver head while longitudinal ribs are formed on the guard intermediate these head protecting sections with side sections at the opposite sides of the guard formed with parts cooperating with parts of the casing to detachably secure the guard in head protecting position on the shaver.

The invention comprehends a number of other magnetic motor (not shown).

features of construction that will be hereinafter pointed out and claimed in the following description and claims, all of the features being cooperative with those referred to above in providing a head guard for shavers that may be constructed in an economical manner and which is convenient for use.

In the drawing:

Fig. 1 is a side elevation of ashaver with the head guard applied thereto.

Fig. 2 is an enlarged fragmentary side elevation of a side adjacent to that shown inFig. 1, with portions broken away, shown in cross section, and illustrating the head guard in cross section in assembled ,position on the shaver.

Fig. 3 is a top plan view of the head guard. Fig. 4 is a bottom plan view of the head guard. Fig. 5 is an end elevation of the head guard. ,y Figu is a longitudinal fragmentary cross section through the head protecting section of the 'guard and the adjacent shaving section of a shaver head.

A conventional form of electric dry shaver is illustrated in the drawing in which casing l forms the usual handle and the housing for the driving means for the shaver which may be in the form of the usual make and break contact type of electro- One end of casing l is formed withone or more channels formed to provide a seat for receiving and mounting a shaver head at 2u in each channel.

The drawing illustrates a shaver with three channels arranged in spaced parallel relation transversely across one end of the casing for receiving three shaver heads 2 as will be particularly apparent from the disclosure in Fig. 2. These shaver heads 2 may be detachably mounted in each channel in independent relation in a manner well-known in the art. Each shaver head comprises a base portion 3 engaged in the channel in casing .I and/an outwardly projecting shaving section 4 formed in a conventional manner with cutter bars (not shown). The ends of each shaver head 2 have reinforcing ribs beyond the shaving section as shown in Fig. 6 which project outwardly beyond the outer surface of the shaving section.

An inner movable cutter 5 is mounted on the inside of shaving section 4 in a conventional manner well-known in the art and has cutter bars (not shown) for cooperation with the cutter bars on shaving section I for cutting cooperation therewith when inner cutter l 5 is reciprocated back and forth relative to shaving section 4. Any suitable means may be provided for securing each shaver head 2 detachably in the channel in the end of casing I, such means not .being illustrated because it does not form part of the present invention.

The drawing also illustrates the shaver as being provided with hair pockets 6 to cover the oppovsite open ends of shaver heads 2 in order to reeach shaver head. In the illustration shown in s the drawing guard "I is provided with three sec- -tions 8 of partially cylindrical shape in cross section. The central section 8 is joined with the two side sections 8 in the manner clearly illustrated in Figs. 2, 4 and 5, by means of a longitudinally extending rib 9, two such ribs being used .to secure the three sections together. This rib is oi considerably thicker cross section, as illustrated in Fig. 2, than head protecting sections 8 in order to form a substantially rigid guard structure longitudinally of the head.

At opposite sides of the guard, head `protecting sections 8 are formed with laterally extending side sections I0 extending laterally from the outer side edges of sections 8 in a manner shown in Figs. k2 and 5. Side sections III extend in substantially parallel relation to each other, as shown in Figs. 2, 4 and 5, and with sections 8 and ribs 9 extend throughout the length of shaver heads 2, as illustrated in Fig. 1. Side sections HI have a greater cross section than head protecting sections 8 in order to make them substantially inexible while sections 8 are formed to be resiliently flexible in order to provide for a limited movement of the free edges of side sections I8 toward and from each other. The resiliency of the guard structure in head protecting sections 8 is such as to normally maintain side sections IIIv rin the parallel relation illustrated in Fig. 2.y l v l The central portions of side sections III are formed with inwardly extending projections II having upper and lower inclined faces I2 and I3 respectively, arranged to form part of complementary interengaging parts or securing means for attaching the guard to shaver casing I. Shaver casing I is provided on opposite sides near the end mounting shaver heads 2 with a plurality of outwardly extending transverse ribs I4 arranged in spaced relation and designed to provide a decorative effect on the exterior of casing I. Rib I4 nearest to the end of casing I mounting shaver heads 2 and the groove I5 between this rib and the next adjacent rib, is so constructed that projectionsvI Ion guard I will engage in grooves I5 at opposite sides of casing I between adjacent ribs I4 forming groove I5.

Through the cooperation of ribs I4 forming one set of complementary parts or securing means to coact with projections II forming the other part of the securing means effective means is provided for retaining guard 'I detachably secured on shaver casing I in a position to protect shaver heads 2. In order to enhance the appearance of the shaver, guard I has the lower edges of side flanges I0 slightly-curved to conform f shaver structure and reduce the to the curvature of ribs I4 as illustrated in Fig. 1.

Thickness simulating and protective flanges Il are formed at opposite ends of side sections III and extend laterally inward therefrom in a manner shown in Figs. 2, 4 and 5, being formed lntegrally at the upper `edges with adjacent portions of head protecting sections 8 where they extend to and merge into side sections I0. These flanges I6 provide for the convenient manual en' gagement of ones lingers with the guard member for flexing the guard member in attachment and removal thereof from the shaver. In addition, these flanges I6 are arranged in perpendicular relation to the adjacent portions of shaver casing I and hair pockets 6. These flanges are arranged so that if the end of shaver carrying head 2 is engaged with another object accidentally, the guard will receive and transmit the force of such engagement when at the sides of the `shaver and at the end adjacent to sides, directly to the casing in order to protect the shaving section 4 of each shaver head from damage.

The head protecting sections 8, ribs 9 and side sections I0 also cooperate in receiving and distributing the force of impacts against the end of the shaver carrying the heads 2 so that imi the end of the,

pacts will be distributed over tendency of impacts from breaking some of the cutter bars. The ends of sections 8 will engage the ribs at the ends of shaver heads 2 in distributing impacts on the guard in order to protect the shaving section with its cutter bars.

vGuard I may be molded of suitable plastic material such as any ofthe materials from the thermo-plastic group as well as any of the materials commonly identified as thermo-setting plastics. It is to be understood that guard 'I may be made of sheet metal, or drawn, forged or cast.

The inherent resiliency of the material including the -form of constructionl of head protecting sections 8 provides guard 'I with a suitable and desirable resiliency andfiexibility that enables the ready removal and application of the guards to the shaver. In applying the guard` to the shaver it is merely placed over the end ofthe shaver carrying heads 2 and pushed into the position shown inv Fig. 2. In pushing it toward the position shownin Fig. 2 from a position above that illustrated, the inclined faces I3 will cam side sectionsl yII'I outwardly over uppermost rib I 4 as shown in Fig. 2 so that projections II will drop into grooves I5 and detachably secure guard 'I in position. In removing the guard from the shaver inclined faces I2 will operate to cam projectionsl II`out of groove I5 when the guard is pushed away from the end of the shaver in any desired manner. The guard may also be gripped at the ends of a side section I0 and manually ilexed outwardly to disengage projections II from grooves I5 and ribs I4 in removing the guard.
