Definitions

  • ABSTRACT 0F THE DES CLGSURE An electrical dry shaver having a reciprocating cutting blade block which comprises a cutting hood mantel foil, a clamping body and a housing head, whereby the cutting head mantel foil is releasably secured in the housing head by means of the clam-ping body.
  • the cutting blade block is resiliently pressed to the cutting hood mantel foil and the latter includes two pin-shaped holders disposed at diametrically opposite sides thereof and serves as its bearing means.
  • the present invention relates to improvements in electrical dry-shavers having a reciprocating cutting blade, in general, and to such electrical dry-shavers wherein the cutting blade resiliently engages a cutting hood foil mantel releasably secured by clamping means to a housing head.
  • the frame-like formed clamping body can be produced of a wire section and can be connected in a simple manner rotatably with the housing head. The rest device permits thereby a simple and fast release and reconnection, respectively, of the clamping body with the housing head.
  • Each of the pin-like holders projects on both sides beyond the cutting hood mantel foil, so that extending portions enter the bearings of the housing head.
  • a rigid securing of the end ranges of the cutting hood mantel foil is thereby excluded; rather they can perform a rotary movement, with the result, that the curving of the cutting hood mantel foil can be varied. Since a rotation is possible in both directions, in dependency upon the occurring forces a reduction, as well as an increase of the curving of the originally bent cutting hood mantel foil can take place. By this arrangement the dangerous rangewise lifting of the cutting hood mantel foil from the cutting blade can be prevented.
  • the rotatability of the holders coordinated to the cutting hood mantel foil can be obtained in a simple manner such, that the holders are formed as round pins which rest in bearings complementary to their ends.
  • the intermediate members have suitable leg members which are arranged tangentially to the rotatably mounted holders.
  • FIGURE 1 is a bottom plan view of a cutting head framework or housing, according to the present invention.
  • FIGURE 2 is a longitudinal sectional elevation taken through the cutting head frame housing, shown in FIG. 1;
  • FIG. 3 is a fragmentary cross-section of the cutting head frame housing disclosed in FIGS. 1 and 2.
  • the shearing head comprises a housing head 3, which is formed integrally. It will be understood that resort may be had to use some metallic materials, alloys, and also plastic materials for this purpose. It will be seen that in order to allow engagement of various types of electrical dry shaving apparatus inside the electric razor itself as well as the head portion, suitable cam projections or lugs 4 may be cast integrally with the housing head 3 which serve the releasable connection with the housing 40 (not completely shown).
  • a framelike clamping body 6 In order to releasably mount a cutting head mantel foil 5 on the housing head 3, there is provided a framelike clamping body 6.
  • the latter is in a preferred embodiment of the present invention, made of a wire of suitable size in cross-section, and bent in generally rectangular shape as best seen in FIG. 1.
  • the one narrow side portion 7 of this clamping body 6 serves as a rotatable bearing for the clamping body 6.
  • a bearing 8 which receives median ranges of the side portion 7 of the clamping body 6.
  • the serving portion of the clamping body 6 formed of a wire section.
  • the supporting member consists of a rest portion 9, which is complementary to the cooperating portions of the clamping body 6.
  • the median range of its narrow side portion 10 rests in the support 9.
  • the parts are pressed along the obliquely formed under-surface 11 until they snap into the resting position 9 of the support 9.
  • Such operation is possible in view of the easily resilient constitution of the side 10 of the clamping body 6.
  • the cutting hood mantel foil 5 is provided with two pin-shaped holders 13. They can for example be made of metal bodies in a suitable bearing support shape. They are on both longitudinal sides of the cutting hood mantel foil 5 and are rigidly secured to the cutting mantel foil 5 by means of an intermediate member 14. As seen best in FIG. 3, the intermediate member 14 is illustrated in cross-section, as showing generally a U-shaped conformation, the shank 15 of which lies in very close engagement with portions of the cutting hood mantel foil 5. In order to make for a really secure and long lasting engagement of these parts, as mentioned, the shanks 15 of the intermediate member 14 can be rigidly secured to the cutting hood mantel foil 5 by suitable means, such as by soldering. In this way the pin-shaped holder 13 mounted with the range of the intermediate member 14 finds a solid and durable seat.
  • each pin-shaped holder 13 extends on both sides to overlie the cutting hood mantel foil 5', expressed differently, the length of the pin-shaped holder 13 is greater than that of the cutting hood mantel foil 5.
  • the projecting portions are employed for anchoring the cutting hood mantel foil 5 within the main housing 3.
  • four bearing positions 16 are provided on the inner wall of the housing head 3, which are arranged to fit properly with the configuration and the measurements of the free end of the pin-shaped holders 13.
  • the clamping body 6 when positioned in the support 9 abuts the bottom of the intermediate members 14 and lholders 13, thereby locking the mantel foils.
  • the cutting blade block 43 is formed in a suitable well known manner, in order that it may engage properly with individual hairs of the user for optimum performance. It may also be observed, that the cutting blade block 43 will move back and forth as a unit by means of the drive disposed in the housing 40. Beneath the cutting blade block 43, is a body of material 44, which is formed of suitable highly elastic plastic or similar material. For example, it can have an intermediate portion made of sponge rubber or synthetic sponge material.
  • An electrical dry shaver having a reciprocating cutting blade block, comprising a cutting hood mantel foil,
  • said cutting hood mantel foil being releasably secured in said housing head by means of said clamping body
  • said cutting blade block being resiliently pressed to said cutting hood mantel foil
  • said cutting hood mantel foil includes two pin-shaped holders disposed at diametrically opposite sides thereof and serving as its bearing means.
  • the electrical dry shaver as set forth in claim 1, which includes an intermediate member connecting said pin-shaped holders with the longitudinal sides of said cutting hood mantel foil.
  • clamping body is frame-like and comprises a rectangularly bent wire section
  • one side of said clamping body is received rotatably in a bearing of said housing head and the opposite side of said clamping body cooperates with a rest means of said housing head.
