INVENTOR DOUGLAS J. PIRC, American national, residing at: 798 N. Greenbrier Drive Orange, Connecticut 06477, E.U.A. m A-A- * THE SHAVE SYSTEM WITH INTEGRAL DRIVER CLEANING BAR AND ELASTIC ELEMENT J ^ FIELD OF THE INVENTION The present invention is directed to a dynamic shaving system and, more particularly, to a dynamic shaving system having a sloping cleaning element to dislodge shaving residues from the shaving system.

BACKGROUND OF THE INVENTION A common problem that safety razors must face is the accumulation of shaving residues between the elements of the machine head that come into contact with the skin. In recent times, most of the * Safety shaving aquinitaß of the market are manufactured with two sheets arranged in a spacing relationship with each other. Typically, an element of. forward protection of the main blade at a fixed distance from the main blade to control the angle at which the surface of the skin being shaved contacts the main blade. The size of the spasm between the two leaves will also affect the flow of the skin over # the cutting edges and therefore needs to be carefully controlled during the manufacture of the head of the razor. The accumulation of beard, soap, skin cells and other shaving residues in these small spaces poses the potential alteration of the passage of the skin through the sharp edges of the blade and can negatively affect the comfort of shaving and his fc flush execution.

Furthermore, it is highly advisable to provide a mechanism for the selective removal of the shaving residues from the spaces defined by the head elements of a razor that come in contact with the skin. ^^? Recent changes in the design of the razor head have led to the commercialization of razor head heads with movable blade elements. Although several elements of the razor head can move with respect to each other, they will not necessarily remove the shaving residues that can negatively affect the overall quality of the shaving. Accordingly, it is also convenient to provide a razor head having at least one movable blade, and preferably at least two moving blades with a wiper element capable of removing shaving residues from among the moving blades.

It is also highly convenient to provide a simple design with a minimum number of parts, in order to facilitate the quick and economical manufacture of the razor head in question. Specifically, it would be desirable to eliminate the need to separately form the tilting elements intended to return the mobile elements that contact the skin to the original post after being w ^. eliminated the forces faced during shaving.

Eetae and other advantages are achieved by the embodiments of the present invention which are described in more detail below with reference to the drawings.

SUMMARY OF I NVENC I ON The present invention is directed to a razor head comprising at least one movable blade that moves in response to the forces it faces during shaving. In accordance with one embodiment, an integral wiper element is provided to selectively dislodge shaving debris from the small spaces adjacent to a sheet. * mobile, and to tilt the moving leaf so as to return it to a normal "home" position after the shaving forces have been removed.

According to a preferred embodiment of the present invention, there is provided a razor head having at least two movable blades, each of which is tilted forward by a pair of elastic fingers which are integrated with the wiper element. In accordance with this embodiment, the cleaning element is provided with a slow-acting button to a frontal projection which allows a person to shave to move the cleaning element forward to dislodge the residues of the shaving, and of multiple elastic fingerres. above and below the frontal projection, which come in contact with the moving leaves. The wiper element advantageously serves the dual purpose of returning the front projection of the wiper element to a retracted position after the person shaving has removed the pressure from the shredder, at the same time driving the sheet forward. * The present invention advantageously reduces the number of separate elements that must be manufactured and then assembled, while at the same time providing the benefit of a dynamic shaving system that allows a user to selectively remove the residues of the shaving that is shaved. fc. they lodge in the spaces of the head of the razor.

These and other aspects of the present invention are discussed later in more detail.

DESCRIPTIVE MEMORY OF THE PRESENT INVENTION The present invention is directed to a razor head having at least one element with dynamic movement that comes into contact with the skin and a cleaning element for wf to dislodge the residues of the shaving from a space created in part by that element mobile. The embodiment of the present invention illustrated in Figures 1-4 comprises a razor head having two movable blades separated by a front projection of a wiper element. As used herein, the term "razor head" includes cartridges that are # designed and manufactured for incorporation into a separate razor, as well as the operating portion of a disposable razor where the parts that come into contact with the skin are incorporated a handle section.

With reference to Figures 1-5, this illustrated embodiment comprises a sheet support structure including a cover IO, f a protective section 20, and side walls 25. The sheet support structure is preferably formed as a single element, integrally molded, by injection molding, for example. A support sheet 30, a cover sheet 40, and the cleaning element 50 are held by the support structure and held therein by the fastener 6. The present design allows advantageously that the cover sheet 40 and the support sheet 30 be supported by the side walls 25 of the support structure for making forward and forward movements. backwards.

The cleaning element 50 comprises a front projection 51 connected to an actuator 55 on which the upper elastic fingers 56, 0 57, and the lower elastic fingers 58, 59 depend. In accordance with the preferred embodiment of the present invention illustrated, all of the cleaning element 50 is constructed as an integral unit, with a higher preference for a material thermoplastic that can be injection molded.

Suitable materials should have sufficient elasticity, corrosion resistance, fatigue resistance, elastic qualities and lubricity under conditions that usually occur during the life of the razor head. For example, an acetic copolymer sold by Hoechst Ce l with the name CELCO-M * "" * is suitable. The elastic fingers illustrated are located on both sides of the actuator 55 and above and below the front projection 51. In this way, the elastic fingers will be properly aligned and will tilt forward the cover sheet 40 and the cover sheet 40. support 30.

In accordance with this illustrated embodiment of the present invention, the interior portions of the side walls 25 of the support structure consist of protrusions 27 projecting inwards, designed to limit the movement of the sheets forward and backward. As illustrated, the cover sheet 40 comprises a pair of notches 42 located on the sides of the sheet 40. The notches 42 are designed to allow the sheet 40 to slide back and forth to a point that is limited by the coupling of l ß protuberances 27 with the front and rear walls of the notches 42. similarly, the support sheet 30 is provided with pieces 32 which are also designed to be coupled with the protuberances 27 which project inwards. According to this embodiment of the present invention, the head of the razor is preferably assembled in inverted form. After that the support structure has. Once formed, it is placed in the inverted position. HE ^ then align the fingers 42 of the cover sheet 40 so that they lie on the projections 27, and the sheet of the cover 40 is lowered into the support structure. The cleaning element 50 is then placed by aligning the upstanding pin 52 upwards with a complementary receptacle 12 formed t on the underside of the cover io. The receptacle IO is designed to receive the spike 52 in such a manner as to allow the cleaning element 50 to move back and forth while the spigot 52 is guided into the receptacle 12. After the cleaning element 50 has been put into position, the support sheet 30 is also lowered into the support structure with the notches 32 aligned with the protuberances 27. The operative assembly ee ft is then held in position by the fastener 60, which can be assembled under pressure or spring in the support structure. In accordance with the illustrated embodiment, the lateral projection 62 of the fastener 60 is designed to fit into complementary grooves 22 formed in the inner sides of the sidewalls 25. In addition, to keep the floor block secured within the support structure. Double sheet illustrated, the bracket 60 is also provided with inclination elements 65 extending upwards, which serve to tilt the sheets and the cleaning element upwards in the direction of the cover O, thus reducing any negative effect produced by the manufacturing tolerances that # could cause unwanted movement, during shaving, of the elements that come in contact with the skin.

From the present description it will be appreciated that the elastic fingers of the cleaning element 50 illustrated, provide on the moving blades a forward-directed pre-charged force that must be overcome by the forces And exerted on the leaves during shaving, before these leaves can move backwards. The magnitude of this pre-charged force can be varied during the manufacture of the razor head of the present invention. For example, the force required to move a sheet can be changed by using more or less elastic material in the formation of the cleaning element 50. Alternatively, it can. change the shape of the elastic fingers so as to increase or decrease the magnitude of the preloaded force. For example, the shape and / or the dimeneioneß of each elastic finger can be changed. The elastic fingers illustrated in the embodiment shown in Figure 6 comprises smaller elastic fingers designed to offer, by virtue of their smaller size, a resistance to the elements that contact the skin, which are driven backwards during the shaving, relatively smaller than the resistance offered by the elastic fingers shown in Figure 2.

Although the embodiment illustrated in the Figures 1-5 of the present invention comprises leaves which they move towards attracts in response to forces occurring during. shaving, it is also within the scope of the present invention to provide a razor head having the advantages of the present invention, including a cleansing element consisting of at least one inclination element integrally formed on the limb, the time that one or more elements are brought into contact with the skin that they move downward in response to the forces that must be faced during shaving. It is also within the scope of the present invention to provide a cleaning element having an integrally shaped tilt element, for tilting an element that contacts the skin, that element not being a sheet. For example, a protection element or a cover can be elastically inclined by the inclination element formed in the cleaning element.

Figure 3 illustrates the "source of origin" position of the cleaning element 50 while Figure 4 illustrates the cleaning element in the front driven po- sition. Figure 5 is a partial enlarged vieta of the razor head shown in Figure 1. Those skilled in the art will observe that the movement of an element that comes in contact with the skin can be m. restricted in other ways without departing from the scope of the present invention.

According to another embodiment of the present invention shown in Figures 6 and 7, a cleaning element 150 comprises four sets of elastic fingers. The elastic fingers located in the central position fulfill functions similar to those shown in the embodiments of Figure 1-5. To reduce the magnitude of the pre-charged forward-directed pressure exerted on the elements that come into contact with the skin, the elastic toes shown in Fig. 6 and 7 are relatively smaller than the elastic fingers shown in Fig. 2. In addition to the pairs of elastic fingers located in position * central, the cleaning element 150 is provided with two additional sets of elastic fingers. A pair is located above and a pair below the eláeticoe fingers that tilt the leaves. As illustrated in Figure 7, the additional pairs of resilient fingers are located so as to be in contact with a movable protective bar 120 and a movable cover element IIO. In accordance with this embodiment illustrated herein of the present invention, each cover element 110, cover sheet 140, support sheet 130, and protection element 120, can move independently of the other moving elements that come into contact with the skin, in response to the forces that must be faced during shaving.

It will be appreciated, therefore, that this embodiment of the present invention advantageously provides a dynamic razor head consisting of multiple movable blades, a movable cover member and a movable protective bar designed to move in response to the forces it must face during shaving, and to be returned to its "home" position by the elastic fingers of a cleansing element when the shaving forces are eliminated.

The various embodiments of the present invention also provide simple and efficiently manufactured razor heads that provide a person shaving a mechanism for the removal of shaving residues that tend to accumulate in small parts of the razor head of the razor. shaving during shaving.

Although the embodiments of the present invention illustrated herein comprise a wiper element with a front projection extending between two sheets with independent movement, it is also within the scope of the present invention to provide a wiper element 1 with one or more projections that they are located so as to remove the shaving residues from other spaces of the head of the razor. For example, a projection of the wiper element can be extended between a mobile protective bar and a fixed blade, i.e. a non-moving blade. Furthermore, in order to obtain the benefits of the present invention, it is not necessary for one or more of the blades to move, since it may be convenient to form a razor head having fixed blades with a mobile protective element and / or an element. of mobile cover. In these cases, the advantages of the present invention where a cleaning element has integrally formed at least one inclination element would also have an advantageous application. * #
