Definitions
- This invention relates to improvements in electric shavers and particularly to the construction of the casing for mounting the electric motor and cutter elements.
- the shaver case has a pair of sections which register in opposed relation to form a compartment housing the electric motor and provide a mounting for the cutter elements, having latching members detachably engaged with portions on each casing section for retaining the casing in assembled relation without the use of screws and without requiring use of special tools for assembling and disassembling the shaver.
- Some of the latching members may also be constructed and arranged to detachably mount the cutter elements on the casing. With such an arrangement the cutter elements and electric motor drive for the cutters may be completely assembled with the casing by means of the latching members.
- the latching members provided by the invention are formed of sheet metal strips or similar material, have central portions for embracing outer portions of both casing sections across the abutting edge portions and projections on opposite ends arranged in opposed relation to engage attaching portions on the casing in cooperative relation to hold the casing sections to gether.
- These attaching members are made so they may be manually snapped onto the casing.
- the cutter elements may also be snapped onto the casing and held by selected attaching members.
- the projections on opposite ends of each attaching member are in the form of resilient fingers to facilitate economic manufacture and a convenient structure for application and removal from the casing.
- FIG. 1 shows a shaver in side elevation constructed according to the invention.
- FIG. 2 is an end elevation thereof.
- FIG. 3 is a horizontal cross-section taken on line 33 of FIG. 1.

- These casing sections may be formed in any suitable man ner and as illustrated in the drawings, are shown as being formed of molded plastic material to provide two half sections.
- Each half section is oppositely formed so that it will provide an imperforate outer wall portion merging into edge wall portions extending in substantially perpendicular relation to the imperforate wall portion with the peripheral edge portion of each casing section termimating in a position so that when the sections are assembled together, the peripheral edges are registered and engaged to form a closed casing.
- the assembled casing houses an electric motor within the compartment formed between sections 2 and 3 by the several wall poltions.
- the casing sections are formed with supporting portions 4 on one side which cooperate to support the cutter elements 5.
- the cutter elements 5 may include one or more shaver heads having inner and outer cutters, three being illustrated in the drawing. These may be mounted on supporting plate 6 having outwardly and upwardly extending ends 7 used to provide suitable parts for cooperation with latch members to detachably secure the cutter elements on the shaver casing.
- Both casing sections are formed on the lower side as shown in FIGS. 1, 4 and 5, with attaching portions 8 in the form of elongated ribs. These ribs are formed adjacent the peripheral edge of the casing and extend outwardly in a direction opposite to the periphery of the casing, as shown in FIG. 5.
- a clamping member 9 is formed of channel cross section having the free edges turned inwardly, as shown in FIG. 5, for embracing ribs 8 in the manner shown in FIG. 5, to detachably secure casing sections 2 and 3 in assembled relation at one side of the shaver. As illustrated in the drawing, attaching member 9 is located at the opposite side of the shaver casing from the portion having the supporting portions 4 and cutter elements 5.
- each casing section is provided as shown in FIGS. 1, 2 and 3, with recesses 10 in the outer surface of supporting portions 4. These recesses provide ribs or shoulder projections 11 on each casing section 2 and 3, as clearly shown in FIG. 3, for cooperation with attaching members 12 in securing the casing sections in assembled relation at the opposite side portion of the casing from attaching member 9. Attaching members 9 and 12 cooperate in securing the several parts of the casing and shaver together.
- Attaching members 12 are formed of sheet metal strips having a center longitudinal rib portion while opposite ends of the metal strip are extended at substantially right angles to the central portion to form end portions or fingers 13. End portions 13 have terminal portions formed to provide inwardly extending securing fingers 14 arranged to engage in recesses 10 so that end portions 13 detachably interlock with projections 11 in detachably securing sections 2 and 3 of the shaver case in assembled relation at opposite ends of supporting portions 4.
- Attaching members 12 are formed of resilient sheet metal so that fingers 14 and ends 13 can flex relative to the center portion of the strip for convenient manual engagement into the assembled position shown in FIG. 3 for holding the shaver sections together.
- Attaching members 12 are also formed in the central portion with resilient attaching fingers 15 extending from the side of attaching members 12. An angle end portion 16 is formed on the end of each finger 15, as shown in FIGS. 1 and 2.
- resilient attaching fingers 15 on the attaching members are arranged at opposite ends of supporting portions 4 on the casing to detachably engage over projecting ends 7 of base plate 6 carrying the cutter elements for detachably retaining the cutter elements detachably assembled in outwardly projecting relation on the shaver casing, as shown in FIGS. 1 and 2.
- Each casing section 2 and 3 is formed, as illustrated in the drawings to provide a motor compartment for an electric motor diagrammatically indicated at 20 of a wellknown form of construction.
- the inner walls of each casing section are provided with a plurality of the inwardly extending bosses 21 formed with recesses 22 at spaced intervals about the sides of each section.
- Motor supports made of resilient compressible material such as composition rubber, are indicated at 23 having supporting portions formed to engage the inner face of bosses 21 and projections from one side thereof engaged in recesses 22 for holding members 23 in position on the bosses.
- Casing sections 2 and 3 are also constructed to provide an aligning means for holding the casing sections in substantially aligned coincident relation when assembled as shown in the drawings.
- This aligning means includes projections 25 formed on casing section 2, as shown in FIGS. 3 and 5, which project outwardly from the periphery of casing section 2 in locations approximately at opposite ends of supporting portion 4.
- Casing section 3 is formed with recesses 26 in the periphery of the casing section in a position to receive projections 25, so that when projections 25 are engaged in recesses 26 both casing sections will register with one another to provide an assembled casing having a neat and smooth appearance about the meeting edges between the two sections.
- FIGS. 1 and 2 The drawings have omitted illustration of a detachable casing section forming a hair pocket, in order to show the attaching members '12, although the casing and supporting portions 4 are constructed so supporting portions 4 will be housed within the detachable casing section also enclosing the shaver heads in a manner well-known in the art.
- a latch is shown at the left hand side of the shaver casing in FIGS. 1 and 2 below supporting portions 4 providing means for detachably connecting the d detachable casing section thereto in a manner well-known in the art.
- FIG. 1 and in the center of FIG. 2 the starting wheel for the motor is illustrated and forms a type of construction also well known in the art.
- the sections 2 and 3 are assembled by first hav ing rib portions 8 engaged in the in-turned edges of attaching member 9 after the motor has been positioned within one section ,of the casing against motor supports 23.
- the casing sections have the opposite sides in spaced relation to one another so that the casing sec.- tions extend in angular relation away from member 9.
- the starting wheel and the latch are positioned between the casing sections and they are then moved toward each other until projections 25 engage in apertures 26 which provides the final alignment of the sections in assembled relation.
- Attaching members 12 are then snapped into the positions shown in FIG. 3 for completing the assembly of the casing with the motor firmly held by motor supports 23 which are compressed under pressure in the casing.
- Cutter elements 5 may then be mounted on the shaver casing by snapping plate 6 into position so that ends 7 are engaged by latch fingers 15.
- FIGS. 6 and 7 show a modified form of construction in which the shaver casing has supporting portions 30 for supporting the cutter elements.
- Attaching member 3 1 is formed of a strip of sheet metal having the opposite side edges bent laterally to form spring fingers 32. The central portion of the strip is formed with an aperture to receive the oscillator arms for the cutter elements.
- the casing is assembled in the same manner as in the construction above described so that when the supporting portions are in contacting relation, attaching member 31 has spring fingers 32 engaged over opposite sides of the supporting portions 30 for firmly clamping the casing sections together in assembled relation.
