Description

[0001] The present invention relates to a razor for a replaceable blade.

[0002] Razors with replaceable blades (the terms are used synonymously within the scope of this disclosure) are used for manual wet shaving, and less frequently for dry shaving, and represent an alternative to classic straight razors, which typically consist of an elongated one-piece steel blade and a handle.

[0003] With a straight razor that uses replaceable blades, the cutting element can simply be replaced when it loses its sharpness. An advantage of this design is the significantly reduced maintenance and sharpening effort, as well as somewhat easier and safer handling compared to a classic straight razor.

[0004] The replaceable-blade razor consists of a handle and a blade holder into which the razor blade (the "blade") is inserted and secured. The blade can be easily replaced when it becomes dull. The blades for replaceable-blade razors are usually standardized double-edge (DE) or single-edge (SE) universal razor blades, available in various lengths (e.g., 43 mm or 65 mm). The handle and blade holder are reusable. Two single-edge blades can also be created by splitting a double-edge standard blade, for example, by breaking the blade or by separating the ribs between the two sharp edges. The invention is applicable to both types of standard blades as well as other forms of flat replaceable blades.

[0005] From DE 10 2019 120 389 A1, for example, a razor with a replaceable blade is known which – in addition to a folding handle – comprises a blade-receiving section that holds a razor blade in a rigid and fixed orientation by inserting the razor blade into an insert section. The blade-receiving section further comprises a clamping element that can be attached to the insert section by means of a tongue-and-groove connection in order to clamp the razor blade inserted into the insert section between the insert section and the clamping element.

[0006] In another design of replaceable-blade razor, a blade holder is located on the head of the razor. A rubber protective lip insert is fixed between two clamping jaws of the blade holder and is pushed forward for removal. The rubber protective lip insert can then be opened by flipping it open to insert the razor blade. After closing, the rubber protective lip insert is pushed back into the blade holder of the razor head until it stops.

[0007] From US Patent 4,630,365 A, another straight razor with a replaceable blade is known, comprising a razor body with a handle and a first blade holder half that is integrally formed with the handle, as well as a second blade holder half that is pivotally connected to the first. A sliding wedge serves to firmly clamp a blade between two clamping surfaces of the first and second holder halves by its sliding movement in a longitudinal groove along the razor.

[0008] From JP S52 12 064 A, a straight razor with a replaceable blade is known, in which a first blade holder half, formed integrally with a handle part, is detachably connected to a second blade holder half by the latter's sliding movement in a dovetail guide in the longitudinal direction of the razor. The razor blade is clamped between the holder halves, with the second blade holder half being pushed away from the first blade holder half by a leaf or coil spring acting between the blade holder halves to fix an engagement position in the dovetail guide.

[0009] Further razors for a replaceable blade with different fastening mechanisms for the replaceable blade are known from JP S63 305 898 A, DE 2 515 183 A1, JP H08 332 288 A and WO 2022 / 126 122 A1.

[0010] One disadvantage of replaceable-blade razors known from the prior art is that the fastening mechanisms fix the razor blade in only one rigid position and orientation, require dangerous forceful manipulations to open the respective fastening mechanism in the presence of the razor blades for replacement, and are particularly difficult to clean in the case of spring clamps due to the inaccessibility of internal areas.

[0011] It is therefore an object of the present invention to create a razor for a replaceable blade that overcomes at least some of the aforementioned disadvantages.

[0012] The invention proposes a razor for a replaceable blade with the features of claim 1. Preferred embodiments are specified in the dependent claims.

[0013] In particular, the invention proposes a razor for a replaceable blade, comprising a blade holder and a handle connected to the blade holder. The blade holder has a base part with a blade receptacle for a replaceable blade and a cover that is movably or removably connected to the base part in order to selectively cover or expose the blade receptacle and the replaceable blade, which, when installed, is located between the base part and the cover. The blade receptacle is movably mounted on the base part to be adjustable between at least two positions, in which the cutting edge of the replaceable blade arranged on the blade receptacle has a different blade exposure from a longitudinal edge of the blade holder.

[0014] The adjustability of the blade exposure through the mobility of the blade holder with the razor blade otherwise fixed in a defined position allows, without disassembling the razor, but within the scope of handling during shaving, a defined extended application range of the razor, which is largely determined by the blade exposure.

[0015] The blade holder may feature a form-fitting and / or magnetic adjustment aid for positioning the replacement blade in a defined position. This facilitates handling the razor blade during replacement until the cover is in place and reliably prevents the razor blade from falling out.

[0016] Preferably, the blade holder is mounted on the base part via a spring mechanism so that it is elastically movable, such that the spring mechanism preloads it into a basic position in which the cutting edge of the replaceable blade is oriented parallel to the longitudinal edge of the blade holder. Preferably, the blade holder is mounted so movably via the spring mechanism that its movement is forced / preloaded in a direction approximately perpendicular to the longitudinal edge of the blade holder. This preload ensures that the cutting edge of the razor blade remains parallel to the longitudinal edge of the blade holder even in different orientations.

[0017] The spring mechanism can comprise two spring elements, preferably leaf springs, which are preferably arranged symmetrically to the blade holder. The spring elements, particularly in the form of leaf springs, are preferably formed from a single material as part of the blade holder and / or the base part. For this purpose, the spring elements and the blade holder, and preferably also the base part, can be manufactured from a single material by a separating manufacturing process, in particular by machining or ablation, or combinations thereof, and further, in particular, by laser cutting or milling. The single-material construction reduces the number of manufacturing steps or assembly and facilitates cleaning because no additional connecting elements or joints are required between the functional components.

[0018] The razor preferably has a movable support element that acts between the base part and the movable blade holder to lock / fix the blade holder in at least two positions. The support element can be a connecting arm or an eccentric or cam wheel, which is articulated / rotatably / pivotally connected to the base part and the blade holder at one end and can engage with the other end of the base part and the blade holder in at least two positions, corresponding to the at least two positions of the blade holder, in a detachable, in particular positive-locking, manner.

[0019] The connecting arm or cam element can be guided by a guide pin in a cam in the other part of the base and the blade holder, so that when pivoted / rotated it can enter several defined detent positions corresponding to the at least two positions of the blade holder. For this purpose, the connecting arm or the eccentric or cam wheel can be articulated / rotatably / pivotally connected to the other part of the base and the blade holder at a pivot point that is arranged symmetrically to the spring elements of the spring mechanism, and can preferably be moved one-handed with a thumb, for example via an actuating projection on the support element when the razor is held by the handle.

[0020] An outer surface of the base part and / or the cover, at least in an area adjacent to the longitudinal edge of the blade holder where the cutting edge of the replaceable blade is exposed, may be provided with a (symmetrical or asymmetrical) hollow grind, semi-hollow grind or flat grind section.

[0021] The longitudinal edge of the blade holder, particularly the base and / or cover, may be serrated in an area where the cutting edge of the replaceable blade is exposed. This serves a safety purpose by preventing longitudinal movement of the blade along the cutting edge and facilitates hair thinning.

[0022] The cover is preferably pivotable about a pivot axis, preferably about an axis perpendicular to the plane of the interchangeable blade, and is connected to the base part. It is preferably lockable to the base part in the position in which the interchangeable blade is covered. A hinge pin of the pivot axis can be detachably coupled to the base part or the cover.

[0023] The invention is described below with reference to an exemplary preferred embodiment of a razor for a replaceable blade and the accompanying drawings. These show: Fig. 1 a side view of the razor in a state where a cover is open and a handle is slightly unfolded, while a razor blade is omitted to illustrate the razor blade's fastening mechanism; Fig. 2 a side view of the razor from Fig. 1 with a razor blade in a state where the handle is fully extended; Fig. 3 A top view of the blade holder in a side view from Fig. 1 as a single unit, with the handle and cover omitted; Fig. 4 A top view of the blade holder in a side view from Fig. 3 as a single unit, with the cover attached and essentially concealing the razor blade fastening mechanism; Fig. 5 A top view of the blade holder as a single component in a side view of Fig. 3 , omitting the razor blade; Fig. 6 a top view of the cover in side view as a single part; Fig. 7 a rear view of the cover as a single component in the side view; Fig. 8 a side view of the cover as a single part viewed in the longitudinal direction; Fig. 9 a cutaway side view of detail CC of the cover in Fig. 4 ; Fig. 10 a side view of the cover and the blade holder / base part with the interchangeable blade positioned between them, viewed longitudinally from the head; Fig. 11 a side view of the handle as a single component in the top view; and Fig. 12 an enlarged representation of the backdrop of the base part as detail B in Fig. 2 in the top view for fixing the support element in several positions.

[0024] The razor 1 for an interchangeable blade K, shown in the figures as a whole and in its essential individual parts, has by design a blade holder 2 and a handle 3 which is connected to the blade holder 2.

[0025] The handle 3 is preferably hinged to the blade holder and can be made in one or more parts. Preferably, in its folded state, the handle encloses the head with the exposure area of ​​the replaceable blade K, which will be described later, and serves as protection against injury during transport and storage. In its unfolded state, at an angle of approximately 180 to 270 degrees from the folded position, the handle 3 is held during shaving to guide the blade holder 2.

[0026] Handle 3 may also feature decorative handle scales, which can be attached to a base. The shape of the handle may also be modified and shaped according to aesthetic or ergonomic considerations. The handle may be positioned with defined detents in the folded state and in one or more unfolded positions to prevent overly loose adjustments and to specify certain defined positions. Alternatively, it may be rigidly and immovably fixed to the blade holder in a preferred working position (for example, in the position shown in the text). Fig. 2 (as shown in the orientation). In this case, it could even be made of the same material as the blade holder.

[0027] The blade holder 2 has a base part 4 with a blade receptacle 5 for the interchangeable blade K and a cover 6 which is movably or removable connected to the base part 4 in order to selectively cover or expose the blade receptacle 5 and the interchangeable blade K which is arranged between the base part 4 and the cover 6 when installed.

[0028] In the embodiment shown, only one cover 6 is provided on a flat side of the head of the blade holder and covers the blade receptacle 5 on this side (see Fig. 4 The other, opposite flat side, and thus also the blade holder 5 on this side, is exposed (see Fig. 2 This facilitates cleaning of the intake area. However, two covers, which may be connected to each other via a hinge pin and pivot together, or a cover spanning both flat sides of the blade holder, may also be movable or removable on both sides of the base part 4 (not shown).

[0029] In this embodiment, the cover 6 is pivotably connected to the base part 4 about a pivot axis 13, which is perpendicular to the plane of the interchangeable blade K, and is preferably fixed to the base part 4 in the position in which the interchangeable blade K is covered by a releasable fastening element 14, in this exemplary embodiment a screw 14 with an enlarged, knurled head, which can be screwed into a threaded bore 14a in the base part 4 of the blade holder. The enlargement and knurling of the head facilitates operation (rotation) with a finger.

[0030] The shaft of the screw 14 is detachably inserted into an outwardly open receptacle 22 in the cover, which together with a uniformly made detent or spring element 22a is formed on the cover 6 (see Fig. 6 A snap-fit ​​connection between the cover and the base part can be used in addition to or as an alternative to such a mechanical fastening means to define an installation position and / or an open position of the cover. A through-opening 24 in the cover allows, when the cover is installed, a view through to a cam 12 in the base part 4, which will be described later and by which the several locking positions of the blade holder are defined, while the rest of the razor blade fastening mechanism is essentially concealed from this side (see Fig. 4 ).

[0031] In this embodiment, a hinge pin of the pivot axis 13 is detachably coupled to the base part 4 by being inserted into a locking receptacle 20 in the base part 4 (see Detail E in Fig. 5 The hinge pin is detachably inserted and, in this embodiment, is formed in the base part as a single piece of material. The locking receptacle 20 comprises an insertion opening 20c that narrows towards an end position of the hinge pin. Two locking projections 20a prevent the hinge pin from disengaging when it is in the end position. The locking projections 20a are elastically displaceable to allow the hinge pin to pass between them by being arranged on thinned wall sections of the insertion opening 20c, which are formed by elongated recesses 20b parallel to the longitudinal extent of the wall sections.

[0032] The pivot axis can also be rigidly fixed to the base part on the one hand and detachably coupled to the cover 6 in the form of a similar snap-fit, releasable mount on the other. A connection of the pivot axis to both the base part and the cover that is fixed on both sides or releasable on both sides is also possible, but is not preferred for reasons of ease of disassembly for cleaning.

[0033] It is also conceivable to have a simple removable attachment of the cover to the base part without a guide between a covered position and an open position with access to the blade holder, or a detachable attachment by means of a positive engagement through a linear sliding connection between the cover and the blade holder, for example via a projection that is guided in a groove, for example as described in the introduction in connection with the prior art.

[0034] A particular aspect of the invention is that the blade receptacle 5 is movably mounted on the blade holder 2 or its base part 4 in order to be adjustable between at least two positions (in the exemplary embodiment, 3 positions) relative to the blade holder, in which a cutting edge K1 of the interchangeable blade K arranged on the blade receptacle 5 has a different blade exposure from a longitudinal edge 7 of the blade holder 2, wherein the cutting edge K1 of the interchangeable blade K is oriented parallel to the longitudinal edge 7 of the blade holder 2 in the at least two positions. In the illustration of the Fig. 1 and 5 The interchangeable blade is not positioned at the blade holder 5 in order to make its function visible.

[0035] The blade holder 5 is designed as an elongated, approximately oval component, which is arranged in a larger recess in the base part that allows the component to move in the plane of the interchangeable blade. In the illustrated embodiment, the movement of the blade holder is limited only by a spring mechanism 9, which will be described later. However, it is conceivable, and in the context of modifications not shown, that the blade holder 5 can also be mechanically guided in a defined direction of movement within the recess, possibly with friction-reducing means such as a low-friction material pairing, and possibly additionally with a sliding insert or a coating.

[0036] The adjustability of the blade exposure by the mobility of the blade holder 5 relative to the blade holder or the base part with the razor blade K which is otherwise fixed in a defined position allows, without disassembling the razor, but within the scope of handling during shaving, a defined extended range of application of the razor, which is largely determined by the blade exposure.

[0037] The defined, fixed installation position of the razor blade K on the movably mounted blade holder 5 is achieved by a positive-locking and / or magnetic adjustment aid 8 in the form of projections 8a for positioning the replaceable blade K, which engage positively with suitable recesses K2 on the replaceable blade K. The positioning aid 8 can utilize further recesses on the replaceable blade for suitable positive-locking fixation in the defined installation position on the blade holder 5 and may provide further corresponding projections.

[0038] The flat interchangeable blade K can be fixed in the defined installation position by magnetic action in addition to the form-fitting fixation (see Fig. 3 The magnetic fixing aid can be designed such that the projections 8a for positioning the replaceable blade are themselves made of or contain magnetic material. In any case, the projections 8a (whether magnetic or not), which may extend beyond the plane of the flat side of the replaceable blade, can be inserted into suitable recesses 23 in the side surface of the cover 6 facing the replaceable blade (see Fig. 7, 9 and 10This also allows for a simple, form-fitting fixation of the cover 6 in the defined mounting position by means of the projections 8a engaging in the recesses 23, optionally in combination with a magnetic fixation of the cover if the projections 8a are made of or with magnetic material. This further facilitates handling of the razor blade during replacement by reliably preventing the razor blade from falling out during the replacement process until the cover 6 is attached, and also supports the positioning of the cover 6.

[0039] In an alternative or additional embodiment, one or more flat permanent magnets may be provided, preferably flush with the surface of the cover 6, in the recess(es) 23 in the side surface facing the interchangeable blade. If permanent magnets are used on both opposite sides (i.e., on the cover and the base), they must have opposite polarities. This allows the positioning of the cover to be guided and facilitated by the magnetic field.

[0040] The blade holder 5 is elastically mounted on the base part 4 via a spring mechanism 9 such that, with the attached interchangeable blade K, it is preloaded by the spring mechanism 9 into a basic position in which the cutting edge K1 of the interchangeable blade K is oriented parallel to the longitudinal edge 7 of the blade holder 2 in a first exposure. Furthermore, the blade holder 5 is movably mounted via the spring mechanism 9 such that its movement from the basic position is essentially always forced / preloaded in a direction approximately perpendicular to the longitudinal edge 7 of the blade holder 2, so that even in one (or more) further position(s) with different blade exposure, the cutting edge K1 is always oriented parallel to the longitudinal edge 7 of the blade holder 2.

[0041] In the illustrated embodiment, the spring mechanism 9 has two spring elements 9a, 9b, which are preferably designed as leaf springs and are preferably arranged symmetrically to the blade holder 5 to enable its parallel orientation. The design of the spring elements 9a, 9b in the form of a leaf spring is particularly advantageous because the spring elements are formed as a single material with the blade holder 5 and / or with the base part 4. The spring elements 9a, 9b essentially represent highly thinned connections between the base part and the blade holder in the form of horizontally U-shaped webs (see Fig. 2 ), whose parallel legs extend in the longitudinal direction of the elongated oval component forming the blade receptacle 5 and are thus elastically deformable to a certain degree in order to allow elastic movement perpendicular to the longitudinal direction in the plane of the interchangeable blade (or in a plane parallel thereto) (see Fig. 5 ).

[0042] The uniform material construction of the spring elements 9a, 9b with the blade receptacle 5, preferably also with the base part 4 as in the exemplary embodiment, can be achieved from a single material-based starting part by a separating manufacturing process, in particular by machining or ablation or combinations thereof, and further, in particular, by laser cutting or milling. The uniform material construction reduces the number of manufacturing steps during assembly and facilitates cleaning because no additional connecting elements or joints are required between individual functional components.

[0043] However, it is conceivable, even without impairing the basic function of adjusting the blade exposure by moving the blade holder relative to the blade mount, to manufacture the device from several components that are assembled together. For example, the spring elements, in particular, could be arranged as separate parts, such as elastic material bodies made of rubber or plastic, or in the form of coil springs, between the blade holder and the base part in such a way that the described mobility and preload of the blade holder relative to the base part is ensured, possibly in conjunction with a mechanical guide for the movement of the blade holder.

[0044] In order to selectively lock / fix the blade holder 5 against the preload force of the spring mechanism 9 in at least two (three in the embodiment) movement positions, the razor has a movable support element 10 that acts between the base part 4 and the movable blade holder 5 and is manually adjustable (see Fig. 2 In the exemplary embodiment, the support element 10 is designed as a connecting arm / lever 10a (alternatively as a rotatably mounted eccentric or cam wheel - not shown), which is articulately / rotatably / pivotably connected to the base part 4 and the blade holder 5 and can engage detachably in a form-fitting manner with the other part of the base part 4 and the blade holder 5 in at least two positions, which correspond to the at least two (in the example three) positions of the blade holder 5.

[0045] The connecting arm (or the eccentric or cam wheel) is guided by a guide pin 11 in a cam 12 in the other by the base part 4 and the blade holder 5 and can enter several defined detent positions 12a-c when pivoting / rotating, which correspond to the at least two (in the example three) positions of the blade holder 5 (see Fig. 4 and the detail in Fig. 12 The detent position 12b corresponds to the home position, and from here the guide pin 11 can be moved slightly to the left or right into the two further detent positions 12a and 12c, which are located at different heights relative to detent position 12b. This forces the blade holder 5 against the preload of the spring mechanism 9, which, due to its symmetrical arrangement, ensures a parallel orientation of the blade holder 5, into a different height position relative to the base part, each corresponding to a different (greater) blade exposure.

[0046] The slightly concave shape of the contour of the cam 12 in the area of ​​the respective detent positions 12a-c holds the guide pin 11 in a defined position at its lowest point until a force and movement are applied that moves the guide pin out of the concave recess and over the lateral elevation. Simultaneously, this movement is guided smoothly along the curvature, at least on one side. The preload from the spring mechanism 9 then forces the guide pin 11 to move into the adjacent, lower detent positions, and thus also the blade holder 5 to the corresponding position.

[0047] The described and illustrated form of the backdrop is to be understood as an example for explaining the function and is open to various modifications which are to be within the scope of the invention, as long as the function of fixing the movement of the blade holder in several movement positions corresponding to different blade exposures is ensured.

[0048] The support element 10, preferably the connecting arm 10a or the eccentric or cam wheel, is articulated / rotatably / pivotally connected to the base part 4 and the blade holder 5 at a pivot point 25, which is arranged symmetrically to the spring elements 9a, 9b of the spring mechanism 9. The support element can be moved between the detent positions, preferably with one hand, by means of an actuating projection raised on a side surface of the support element 10, using the thumb of one hand when the razor 1 is held by the unfolded handle 3.

[0049] The eccentric or cam wheel in the variant of a support element not shown can be designed in the form of an eccentrically mounted wheel with a guide pin protruding from it, so that a rotation of the wheel by engaging (for example with the thumb of the hand holding the knife) the guide pin, for example to the left or right from a basic position, causes the described displacement of the guide pin in the cam to a respective side and in the vertical position.

[0050] According to the representation in Fig. 10 is / are an outwardly facing outer surface 4a,6a of the base part 4 and / or the cover 6 at least in an area adjacent to the longitudinal edge 7 of the blade holder 2, on which the cutting edge K1 of the interchangeable blade K is exposed, provided with a symmetrical or asymmetrical hollow grind, semi-hollow grind or flat grind section 4b;6b.

[0051] The geometry of the ground outer surfaces 4b, 6b in relation to the blade edge K1, with a radius of curvature of 10 mm and a reduced thickness of 0.5 mm for the base and cover on both sides of the cutting edge K1 in the area of ​​the longitudinal edge 7, can, under minimal exposure, ensure that at an angle between skin and blade between 10° and 30°, the longitudinal edge 7 of the blade holder 2 rests on the skin, and thus the blade protrudes only minimally beyond the longitudinal edge 7. This significantly minimizes the possibility of cuts when the razor blade is guided over the skin at precisely this angle.

[0052] Such a hollow grind, semi-hollow grind, or flat grind section (symmetrical or asymmetrical) in an area adjacent to the longitudinal edge 7 of the blade holder 2 can also be used in a variation of the razor where two covers are attached to either side of the blade holder. In this case, the outward-facing surfaces of the two covers are ground accordingly.

[0053] While in the illustrated embodiment the longitudinal edge 7 of the blade holder 2, in particular of the base part 4 and / or the cover 6, is straight in the area where the razor blade is exposed, it can be serrated at least in part of the area where the cutting edge K1 of the replaceable blade K is exposed (not shown). This design enhances safety by preventing longitudinal movement of the blade along the cutting edge K1 and facilitates hair thinning.

[0054] The blade holder 5 can generally be designed to accommodate standard single-edge or double-edge flat replacement blades (as described in the introduction). However, it can also be adapted to any specific replacement blade by adjusting the dimensions (specifically the distance between the base and the cover) and the blade holder, in particular the positioning features, to the respective contour of the replacement blade.

[0055] Straight razors are distinguished by various head shapes. The most well-known are the round head, the square head, the Spanish head, the French head, and the barber's notch. The round head is the easiest to handle and is therefore very suitable for beginners. The other heads offer advantages for precise contouring due to their defined edges. The head 15 of the straight razor of the invention, specifically the end of the blade holder with base part and cover at the distal end opposite the tang 17 (see Fig. 2 ), on which the blade holder 2 is held stably with the ring finger, can optionally be designed according to all these head shapes.

[0056] In this embodiment, the base part 4 of the blade holder 2 is reduced in thickness (perpendicular to the plane of the interchangeable blade) on one side, adjacent to the tang 18, i.e., the shaft of the blade holder, within the movement area of ​​the cover. This allows the cover to be inserted flush into the recess / recess even when the base part and cover overlap in the head area, thus reducing the excessive thickening of the blade holder in the head area. When using covers on both sides, the blade holder can be recessed on both flat sides.

[0057] The tang 18 may also be grooved on the top and / or bottom to improve grip / friction (see details D and F at 19 and 21 in Fig. 5 ).

[0058] Although the blade holder 2 and the cover(s) 6 in the embodiment have been described as one-piece elements, which may preferably be made of a stainless metal such as titanium or a titanium-containing alloy, optionally with a biocidal coating such as copper or silver, the blade holder and / or the cover(s) may also be composed of several components, optionally also of different materials, with or without a coating.
