Definitions
- the present invention relates to a shaving head comprising at least one cutting blade and actively driveable skin stretching means arranged behind said cutting blade relative to a cutting direction of said cutting blade.
- a shaving head ofthe type mentioned above is well known in the art.
- Such a shaving head is also known as a safety razor.
- a problem that still occurs in connection with the known safety razors is the possibility that nicks and cuts or irritations ofthe skin to be shaved are created during the shaving operation. This problem can at least be reduced by providing skin stretching means, for example in the form of a driven roller, behind the cutting blade.
- skin stretching means for example in the form of a driven roller, behind the cutting blade.
- Such a solution is known from DE19514228A1.
- This documents discloses a razor having a shaving head ofthe above mentioned type, wherein a first roller is provided in front ofthe cutting blades and a second roller is provided behind the cutting blades. The first roller is driven by moving the shaving head over the skin.
- first roller and the second roller are coupled by a gear wheel such that the second roller is driven to rotate faster than the first roller to provide the skin stretching effect.
- the desired skin stretching effect is achieved, only if the person using the razor properly inclines the handle, and thereby the shaving head, such that both the first and the second roller properly contact the skin to be shaved. This is not possible in all conditions of use.
- a shaving head in accordance with the invention is characterized in that it comprises means for providing a pivot axis between the shaving head and a handle attached or attachable to said shaving head, said pivot axis being arranged at least essentially parallel to said cutting blade.
- the solution in accordance with the present invention provides a pivot axis which ensures that the actively driveable skin stretching means properly contact the skin to be shaved, under all conditions of use and at different handle angles.
- a constant force ratio between a pressure force applied to the skin stretching means and pressure forces applied to other parts ofthe shaving head, especially a pressure force applied to guard means discussed in detail below.
- This constant force ratio results in a more constant driving force ofthe skin stretching means on the shaving head, and thereby control ofthe razor during shaving is improved.
- Stretching the skin behind the cutting blade under all conditions of use stiffens the hair anchoring and raises the hairs. A stiffer hair anchoring and raised hairs enlarge the chance of cutting the hairs, reduce pulling on hairs and give a cleaner cut.
- stretching the skin reduces skin doming in front ofthe cutting blade and improves the force balance between the cutting blade and the skin. This leads to improved safety and comfort.
- the means for providing the pivot axis may be realized by any suitable solution known in the art, especially by a hinge, an integral hinge, a coupling mechanism also used to couple the shaving head to the handle, or snap-in hooks.
- a particular embodiment of a shaving head in accordance with the invention is characterized in that between said shaving head and said handle, when attached to the shaving head, there is provided at least one spring element.
- the spring element preferably is arranged to limit the pressure the user exerts on the skin to be shaved.
- the spring element may form a part of the handle and/or it may connect a section ofthe handle to the shaving head.
- a particular embodiment of a shaving head in accordance with the invention further comprises guard means arranged in front of said cutting blade relative to said cutting direction of said cutting blade.
- the guard means may for example be realized by a further roller or by a gliding element, for example a gliding element having a rectangular cross section and comprising grooves in the surface intended for contact with the skin.
- said guard means are adapted to perform a hair erecting function. If the hair is erected before it is cut by the cutting blade, a closer cut is obtained. Additionally or alternatively it may be advantageous if said guard means are adapted to perform a lubricating function.
- said guard means comprise at least one strip arranged parallel to said cutting blade.
- said pivot axis is arranged such that a force component applied perpendicularly to said cutting direction during a shaving operation is distributed at least essentially in equal parts to said actively driveable skin stretching means and said guard means. At least in some cases this may be effected by placing the pivot axis exactly in the middle between the actively driveable skin stretching means and the guard means. In general the optimal position ofthe pivot axis depends on the friction between skin and guard means, the friction between skin and actively driveable skin stretching means as well as the traction ofthe actively driveable skin stretching means. In many cases the optimal position ofthe pivot axis lies between the above mentioned middle position and the guard means.
- a preferred embodiment of a shaving head in accordance with the invention is characterized in that said pivot axis is arranged closer to said guard means than to said skin stretching means.
- the force ratio between the force applied to the skin stretching means and the force applied to the guard means is kept at least essentially constant under all conditions of use, especially for different handle angles.
- said means for providing a pivot axis parallel to said cutting blade comprise first coupling means for coupling said shaving head to said handle. Such first coupling means are especially advantageous if for replacing the cutting blade the whole shaving head is replaced.
- said actively driveable skin stretching means comprise at least one actively driveable roller.
- This roller may be intended for direct contact with the skin.
- a closed loop system for example a closed loop web, supported by the actively driveable roller and at least a further roller.
- the sense of rotation of said roller when active during a shaving operation, corresponds to its reeling sense of rotation relative to said cutting direction, and the rotational speed ofthe actively driven roller is higher than the rotational speed that would result from the movement ofthe shaving head.
- said actively driveable skin stretching means are driven via a movement ofthe shaving head over skin to be shaved.
- a further roller or a wheel may be driven by moving the razor and the further roller or the wheel may drive the skin stretching means with a suitable gear ratio. Solutions similar to the one shown in DE19514228A 1 may also be used.
- said actively driveable skin stretching means are driveable by an electromotor.
- said electromotor is associated with said shaving head. This makes sense particularly in cases where the cutting blade may be renewed separately from the shaving head.
- said electromotor is associated with said handle. This is especially advantageous if the whole shaving head is replaced for renewing the cutting blade.
- the shaving head preferably further comprises second coupling means for coupling said skin stretching element to said electromotor.
- the second coupling means may for example take the form of two engaging gear wheels, one associated with the handle comprising the electromotor and the other associated with the shaving head.
- Fig. 1 is a simplified and schematic depiction of a first embodiment of a shaving head in accordance with the invention
- Fig. 2 is a simplified and schematic depiction of a second embodiment of a shaving head in accordance with the invention
- Fig. 3 is a simplified and schematic depiction of a third embodiment of a shaving head in accordance with the invention
- Fig. 4 is a simplified and schematic depiction of a fourth embodiment of a shaving head in accordance with the invention.
- Fig. 1 is a simplified and schematic depiction of a first embodiment ofthe shaving head 8 in accordance with the invention.
- the shaving head 8 is coupled to a handle 22 by first coupling means 38.
- the first coupling means 38 may for example take the form of one or more snap-in hooks provided at the shaving head 8 for snapping in in one or more respective bridges provided at the handle 22.
- the shaving head 8 comprises two cutting blades 10,12 arranged such that a cutting direction 16 results. Relative to the cutting direction 16, behind the cutting blades 10, 12 there are provided actively driveable skin stretching means 14.
- the actively driveable skin stretching means 14 comprise a roller 32 which may be driven by an electromotor 36 associated with the shaving head 8.
- the roller 32 is driven such that the sense of rotation 34 corresponds with the reeling sense of rotation 34 relative to the cutting direction 16.
- the guard means 28 comprise a strip 30 having a rectangular cross section in general and being provided with grooves in the surface intended for contact with skin 40 to be shaved.
- roller 32 is driven by the electromotor 36 to rotate in the sense of rotation 34 and with a rotational speed that is higher than the rotational speed that would result from the movement ofthe shaving head 8 over the skin 40.
- the means 18 are made integral with the first coupling means 38 mentioned above.
- the location ofthe pivot axis 20 is essential for the present invention since this location defines how a force component 42 resulting from the pressure exerted on the handle by the user is distributed to the skin stretching means 14 and the guard means 28.
- the force component 42 having the magnitude 2F is distributed equally to the skin stretching means 14 and the guard means 28. In the embodiment shown in Fig. 1 this is achieved by providing the pivot axis 20 exactly in the middle between the skin stretching means 14 and the guard means 28.
- Fig. 2 is a simplified and schematic depiction of a second embodiment of the shaving head 8 in accordance with the invention.
- the embodiment shown in Fig. 2 differs from the embodiment of Fig. 1 in that electromotor 36 is associated with the handle 22. Without being limited thereto, this is especially advantageous in cases where the cutting blades 10, 12 are renewed by replacing the whole shaving head 8.
- the electromotor drives the roller 32 via two drive shafts 44, 46.
- Fig. 2 additionally indicates an area 52 which is preferred for arranging the pivot axis 20. As may be seen from Fig. 2, this area 52 in the horizontal direction extends between the middle between the actively driveable skin stretching means 14 and the guard means 28 and the guard means 28 themselves. In the vertical direction the area 52 extends between the upper surface and the lower surface ofthe shaving head 8. Therefore, in many embodiments ofthe shaving head 8 in accordance with the invention there is a tendency to locate the pivot axis 20 closer to the guard means 28 than to the skin stretching means 14.
- Fig. 3 is a simplified and schematic depiction of a third embodiment ofthe shaving head 8 in accordance with the invention.
- FIG. 3 differs from the embodiment of Fig. 1 in that the handle 22 comprises a flexible portion or spring element 24.
- the spring element 24 is provided to limit the pressure exerted by the user on the shaving head 8.
- Fig. 4 is a simplified and schematic depiction of a fourth embodiment ofthe shaving head 8 in accordance with the invention.
- the embodiment shown in Fig. 4 differs from the embodiment of Fig. 1 in that the pivot axis 20 is located in front ofthe cutting blades 10, 12, and in that there is provided a spring element 26 between the handle 22 and the shaving head 8.
- the pivot axis 22 is arranged in front ofthe cutting blades 10, 12 to limit the pressure exerted by the user on the cutting blades 10, 12 and the roller 32. It is to be noted that any reference signs used in the claims shall not be construed as limiting the scope ofthe invention.
