Description

Razor with deflectable head and replaceable blade

Technical Field

The present invention relates to razors, such as a razor having a deflectable head and replaceable blades.

Background

Razors have become popular and are used by individuals of different genders for their shaving needs.

Double-edged shaving devices have long been known. By using blades composed of low cost thin steel, the solution of disposing of the blade after a limited number of uses becomes widespread and economical, so that sharpening or grinding is not required. The safety features of such razors are: protecting the user from other components than the blade edge is attractive to the user. Based on the orientation of the handle and blade, the user needs to grasp the correct skills to achieve optimal shaving. Disposable razors use small, thin blades that are exposed only at the edges; disposable razors have a deflectable head that matches to some extent the contour of the body area to be shaved. Disposable razors are only suitable for short use times due to the disposable blades designed as disposable products and their limited life.

Alternatively, there are razors that include a double-edged blade. Many of the current safety razors use double-edged blades and clamp the blades onto the head of the safety razor, holding it. Typically, the blade edges are exposed on each side of the razor head. Many of these safety razors do not include a deflectable head, so the user needs to hold the razor and blade at a particular angle to the body part to be shaved in order to achieve a proper shave. This may lead to a lengthy process that does not always provide the desired thorough shave.

US 841 942A and US 956 532A have disclosed razors with replaceable blades. In WO 2016/081795 A1 a razor is disclosed having a handle and a head, the head being deflectable on the handle, wherein the head has a frame and a cover, the cover being deflectable on the frame; the document also discloses at least one razor blade separating element, which is arranged between the frame and the cover portion of the head.

WO 2016/081795 A1, in particular paragraph [0040] of its specification, also proposes providing two "half blades" or halves of a double-edged razor blade by dividing the blade in half. Each half may contain one razor blade. Wherein the "half blade" of the starting form may also be provided without the need to split the double-edged razor blade into two halves. By applying a "half blade" in the head of the razor, the razor is able to provide a configuration comprising several shaving blades for shaving a person's face. The proposal also proposes that a specific "half blade" can be designed and configured such that it is personalized to match the frame of the razor and to the cap of the head.

Disclosure of Invention

It is an aim of some embodiments of the present invention to provide a razor having at least one easily replaceable shaving blade and which takes advantage of advanced razor technology.

To this end, some embodiments of the invention provide razors comprising: a handle and a head portion deflectable on the handle; wherein the head has a frame and a cover, and at least one razor blade having a blade edge and supported between the frame and the cover; the at least one shaving blade is mounted in a replaceable manner between the frame and the cover part, the at least one shaving blade being insertable between the frame and the cover part by means of an operatively, eccentrically arranged securing member which is insertable through an eccentric recess in the at least one shaving blade, and the at least one shaving blade being connectable to the frame and to the cover part by means of the securing member.

Preferably, a number of shaving blades are embedded in the head of the razor of some embodiments of the invention. Preferably, the razor blade is a half blade as disclosed in, for example, WO 2016/081795 A1. The securing member is eccentrically disposed in a symmetrical manner so as to be adjacent a side edge of the at least one shaving blade.

Preferably, the securing member passes through a V-shaped projection on the rear side of the razor blade, i.e. on the longitudinal edge opposite the blade edge.

The securing member is thus arranged very close to the edge of the at least one shaving blade without widening the shaving apparatus and without occupying a central area of the razor, which is left free for all the movements required for performing a shaving by means of the razor during shaving. As a result of the proximity of the fastening member to the blade edge, the blade can be clamped well to the frame in general, but in particular at the front blade edge.

On the basis of the symmetrical eccentric arrangement of the fastening members, a specific geometry of the head can be achieved, which ensures excellent access to the problem area to be shaved, in particular by means of a central recess on the upper edge. This geometry is particularly advantageous for use of the razor in the region between the upper lip and the lower edge of the nose. This applies correspondingly to other anatomically difficult to reach areas to be shaved and to the problem areas. In any case, the position of the fastening member ensures that skin injuries are avoided and at the same time that the skin site to be shaved is easily accessible.

Based on the securing member, the razor blade or blades can be easily replaced. The securing member is releasable or releasable with respect to the head.

The at least one shaving blade and spacer are exposed by removing the securing member, the spacer being arranged between the shaving blade, or between the shaving blade and the cover, or between the shaving blade and the frame. The spacer may be reusable in the event that the at least one shaving blade needs to be replaced due to dulling.

Preferably, the razor only produces a single type of metal scrap that can be recycled. This avoids plastic waste, since only the doctor blade made of metal has to be removed and can be easily recycled as scrap metal.

The amount of waste material is significantly reduced when using the razor of the present invention compared to commercially available and partially market leading systems such as replacement heads or disposable razors composed of composite materials.

This can greatly ease the burden on the environment and save limited resources.

If at least two shaving blades are provided in the head of the razor, a small distance is required between the blade edges of the at least two shaving blades, which enables a thorough, smooth, safe and atraumatic shaving.

In a preferred embodiment using at least two shaving blades, the shaving blades are separated by an intermediate sheet located between the shaving blades.

A smaller distance of, for example, less than 1mm, preferably greater than 0.3mm, is produced on the one hand by the spacing of the blades defined by the spacers located between the shaving blades, and on the other hand by the position of the edge of the upper shaving blade displaced rearward relative to the edge of the lower shaving blade.

According to some embodiments of the invention, the position of the rearward displacement of the upper blade relative to the lower blade is defined by the abutment of the razor blade on the front and/or rear bevel, said bevel being provided on the frame and/or the cover. The angle of the bevel with respect to the base surface of the frame may be between 10 ° and 60 °. As an alternative to a bevel, a step may be provided in the frame and/or in the cover for abutment of the razor blade and the spacer. The abutment ramp may equally be constituted by other elements such as screws.

The bevel defines the horizontal position as well as the vertical position of the spacer.

According to a preferred embodiment, the spacer is constructed as follows: in the rear region of the spacer, i.e. on the side facing away from the edge of the razor blade, a channel is created above the upper edge of the razor blade, which enables the hair, dander, shaving foam and water removed by the shave to flow out backwards. This allows easy maintenance of the cleaning of the razor head.

By arranging the head relative to the handle, a movable, in particular rotationally movable and/or elastic support is achieved, whereby the head can follow the contour of the part to be shaved, thereby achieving a smooth and safe shaving.

In the case of two securing members, a releasable locking mechanism is provided and arranged on the head of the razor for holding the frame and the cover together. The releasable locking mechanism may comprise knurled nuts, each disposed on a threaded pin.

According to a preferred embodiment of part of the embodiments of the invention, the two securing members each comprise a threaded pin fixedly connected in the frame or in the cover, on which threaded pin a nut, preferably a knurled nut, is located, by means of which nut the frame and the cover and the razor blade and the spacer located therebetween are clamped.

The securing member clamps the cover or frame to the frame or cover vertically or at an angle of at most 40 ° from vertical. Wherein the vertical line is defined by a face of the at least one shaving blade.

According to one embodiment of the invention, a threaded pin is provided, acting as a securing member, which is fixedly connected to the knurling wheel and screwed into the cover part, thereby clamping the frame to the cover part, or screwed into the frame, thereby clamping the cover part to the frame.

Advantageous further developments are found in the dependent claims and in the description, in particular in connection with the figures.

The handle is preferably ergonomically designed, resembling an S-shape, to avoid unintended twisting during shaving.

The handle, the frame, the cover and the nut are either entirely made of metal and are for example constructed as zinc die-cast members or are at least partly made of plastic such as polypropylene. According to a further preferred embodiment, the handle is composed, for example, of metal on its top side and of plastic on its bottom side. In this case, the underside of the handle may be matched to the position of the fingers of the person performing the shave.

In any event, by using a razor that is detachable and can be easily detached by loosening the knurled nut, the metal razor blade can be replaced more quickly and easily.

Preferably, the head of the razor is itself resilient; furthermore, the head of the razor may also be supported in a movable, in particular rotationally movable, manner relative to the handle and/or resiliently supported.

According to a preferred embodiment of some embodiments of the invention, the head is supported by a sleeve relatively fixed to the handle by means of an element movable with the head.

Preferably, the element is supported relative to the sleeve by a spring.

It is also preferred that the head is connected to two elongate elements of the handle by the frame.

According to another preferred embodiment, the movable element and the sleeve are arranged between the elongated elements.

Preferably, the head is movably, in particular rotatably, fixed to the extension element by means of a pin or screw, and/or is elastically fixed.

Detailed Description

Razor 1 (fig. 1-14) includes a handle or grip 2 and includes a razor head or head 3, which is preferably constructed as a deflection head.

The handle 2 comprises two elongated elements 4,5 between which the head 3 is received on the sides by means of a pin or screw 6. The pin or screw 6 is inserted through a bore in the extension element 4,5 and laterally into the frame 7 of the head 3. Furthermore, the pin 6 is held in the extension elements 4,5 or in the frame 7 in a press-fit or screwed manner, for example by means of a snap connection, so that the head 3 maintains a connection with the handle 2 in a deflectable manner.

Between the extension elements 4,5, a sleeve 8 extends in the direction of the longitudinal axis of the handle 2, said sleeve being fixedly connected to the handle and constituting an extension of the handle 2 towards the head 3. The sleeve 8 accommodates a movable element 9, which is supported against the handle 2 by a coil spring 10. A helical spring 10 is accommodated through a central bore 11 of the handle 2, which bore extends in the direction of the longitudinal axis of the handle.

This head is mounted elastically against the handle 2 by means of an element 9 which rests on the head 3 on the side facing away from the handle 2. Based on the element 9, the head 3 can deflect during shaving and the head 3 can be turned back again to its original position relative to the handle 2 after removal from the abutment profile. Wherein the end position of the head 3 relative to the handle 2, which can resist the spring force of the helical spring 10, is defined by a projection 12 provided on the frame 7 of the head 3, which projection constitutes a stop for the movable element 9.

The cover 15 is laid onto the frame 7 of the head 3 together with the shaving blades 13 and the spacers 14 and is then fixed by means of the fixing elements 16, 17.

The fastening elements 16, 17 consist of threaded pins which can be screwed by means of knurled nuts 18, 19 which project from the frame 7 on both sides on the underside of this frame, and which are then arranged simultaneously close to the side edges of the scraper blade 13. This ensures that: in any position of the razor 1, the knurled nut does not contact and injure the skin during shaving or cause obstruction during shaving.

The cover 15 is pushed over the frame 7 by means of the fastening elements 16, 17 such that these are located in the recesses 20, 21 of the frame 7 (fig. 3, 10). This allows the razor blade 13 to be easily removed from the head 3 together with the spacer 14 and a new razor blade 13 to be reinserted.

As an alternative to the shown mating of the fastening elements 16, 17 with the knurled nuts 18, 19, other fastening elements may also be used, such as snap elements pressed into corresponding snap holes and the like.

The fastening elements 16, 17 connect the cover 15 with the frame 7 in such a way as to pass through V-shaped grooves 23 (fig. 10) on the rear edge of each of the razor blades 13, so the fastening elements 16, 17 preferably have a certain inclination with respect to the frame 7 and the cover 15, which corresponds to: the leading edge of the razor blade 13 is at an angle to the face of the razor blade 13.
