Description

[0001] Cross-reference to related applications

[0002] This application claims benefit from European patent application EP20187986.3, filed on 27 July 2020, the contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of razors, and more particularly to razors for wet shaving. Background Technology

[0004] Razors for wet shaving having a handle, a razor head, and an adapter for connecting the razor head to the handle are known in the art, for example from EP 2 879 845 B1.

[0005] The purpose of this disclosure is to provide a razor head and an adapter that ensure a secure connection between the razor head and the handle, which facilitates manufacturing and installation. Another purpose of this disclosure is to achieve an improved pivoting property of the razor head relative to the handle. Summary of the Invention

[0006] This disclosure relates to a razor head and adapter as claimed in claim 1. The dependent claims describe embodiments of this disclosure.

[0007] An adapter is designed to connect to the razor head and to the handle, wherein the razor head is rotatable relative to the adapter about an axis of the razor head. According to this disclosure, a razor head biasing component is at least partially disposed within the adapter. This facilitates manufacturing and installation.

[0008] The shaver head biasing component may include a compression spring element and a pusher element for pushing the shaver head into a resting position. The compression spring may be entirely contained within the adapter, while the pusher element may be only partially contained within the adapter. The resting position of the shaver head can be defined as the maximum rotational position of the shaver head relative to the adapter. When the shaver head is mounted on the adapter, a portion of the pusher element protruding from the adapter may engage a portion of the shaver head. When the handle remains stationary, the shaver head may rotate about its axis of rotation at least up to 20 degrees, particularly from 0 degrees to 40 degrees (where 0 degrees corresponds to the resting position of the shaver head and 40 degrees corresponds to the fully pivoted position of the shaver head), the axis of rotation being perpendicular or substantially perpendicular to the handle's centroidal axis extending along the handle. When the shaver head rotates away from the resting position, particularly when the user moves the shaver head along the curved surface of the skin, the compression spring of the shaver head biasing component may be compressed.

[0009] The adapter is adapted to extend from the handle end to the head end, wherein the adapter may include an opening extending from the head end to an internal portion of the adapter, and wherein a shaver head biasing component can be mounted within said opening of the adapter. This facilitates the mounting of the shaver head biasing component to the adapter. Furthermore, the main components of the shaver head biasing component, particularly the spring element, remain clean during use and are less affected by shaving foam that could negatively impact the function of the spring element.

[0010] The adapter may also include at least one opening extending from the handle end to an internal portion of the adapter. The opening may have one or more first protrusions on the side of the adapter designed to connect to the shaver head, wherein the pusher element may have one or more stop elements for engaging the one or more first protrusions, preventing the pusher element from extending outward from the adapter beyond its maximum extension range. This feature also facilitates the mounting of shaver head biasing components within the adapter.

[0011] According to another aspect of this disclosure, the actuator element and the compression spring can be manufactured as a single piece, particularly by injection molding. This is advantageous for the manufacture of the shaver head biasing component, as it can be mounted as a single piece within the adapter. The compression spring may have a wave shape including one or more U-shaped structures, wherein the wave shape extends in a plane. The adapter may have two flat surfaces adjacent to the one or more U-shaped structures on both sides to provide guiding structures within the adapter for controlled compression of the compression spring.

[0012] When not installed and not biased, the razor head biasing component can have a length ranging from 10 mm to 20 mm, a width ranging from 2 mm to 12 mm, and a height ranging from 0.8 mm to 3 mm.

[0013] The razor head may include a housing designed to connect to an adapter. It should be understood that the razor head housing may include one or more housing portions, particularly a front housing portion and a rear housing portion, wherein at least one razor blade (particularly three, four, or five razor blades) is contained within the housing.

[0014] According to another aspect of this disclosure, the adapter may include one or more elements having an arcuate shape. The head end of the adapter may include a pair of arms, each arm having an arcuate element. The shaver head housing or a portion thereof may also have one or more first elements having an arcuate shape, designed to engage the one or more arcuate elements of the adapter. Specifically, the one or more first arcuate elements of the shaver head may have one or more convex surfaces for engaging and / or mating with one or more concave surfaces of the one or more arcuate elements of the adapter. The arcuate elements of the adapter and the arcuate elements of the housing cooperate with each other to provide a well-defined rotation of the shaver head relative to the adapter, which also ensures better functionality of the shaver head biasing component.

[0015] The shaver head housing or a portion thereof may also have one or more second elements with an arcuate shape, designed to engage the one or more arcuate elements of the adapter. The one or more second arcuate elements of the shaver head may have one or more concave surfaces for engaging and / or mating with one or more convex surfaces of the one or more arcuate elements of the adapter. Thus, the one or more arcuate elements of the adapter can be held between the one or more first arcuate elements of the shaver head and the one or more second arcuate elements of the shaver head.

[0016] The one or more concave surfaces of the one or more adapter arcuate elements of the shaver head and the one or more convex surfaces of the one or more first arcuate elements may correspond to a portion of the surface of a cylindrical tube having a first radius of curvature. Furthermore, the one or more convex surfaces of the one or more adapter arcuate elements of the shaver head and the one or more concave surfaces of the one or more second arcuate elements may correspond to a portion of the surface of a cylindrical tube having a second radius of curvature, wherein the first radius of curvature is smaller than the second radius of curvature. Specifically, the first radius of curvature may be in the range of 2 to 8 mm, more specifically in the range of 4 to 6 mm, and the second radius of curvature may be in the range of 5 to 10 mm, more specifically in the range of 6.5 to 8 mm.

[0017] Furthermore, the one or more arcuate elements of the adapter may have one or more second protrusions for engaging one or more stop elements of the shaver housing. The one or more arcuate elements of the adapter may also have one or more second protrusions on their concave surfaces for engaging one or more stop elements, the stop elements being arranged adjacent to or integrally formed on the one or more second arcuate elements of the shaver head. When the shaver head is in a stationary position, the one or more second protrusions of the one or more arcuate elements of the adapter can engage the one or more stop elements of the shaver housing.

[0018] According to this disclosure, the razor head can be connected to a handle on top of an adapter. The handle may include a tongue or extension adapted to be received within the adapter, wherein the tongue or extension of the handle is adapted to be slidably received within an opening in the adapter. Furthermore, the handle and the adapter may be designed to be connected via a snap-fit ​​connection.

[0019] The handle may include an annular element configured to be actuated or rotated at least partially about the axis of the handle, thereby releasing the connection between the handle and the adapter. The annular element may be biased into a rest position to hold the adapter in a locked state relative to the handle.

[0020] The adapter may include one or more third protrusions on one side of the handle, wherein the one or more third protrusions may be disposed within a recess of the adapter. The annular element may include one or more engaging elements for engaging the one or more third protrusions of the adapter to hold the adapter in a locked state relative to the handle. The one or more engaging elements may be disengaged from the one or more third protrusions of the adapter by actuation or rotation of the annular element. Attached Figure Description

[0033] Embodiments of the writing instrument according to this disclosure will now be described with reference to the accompanying drawings.

[0034] Figure 1 A razor 1 according to an embodiment of the present disclosure is shown, which includes a razor head 2, a handle 3, and an adapter 4 for connecting the razor head 2 to the handle 3. Figure 5 As can be seen, the razor head 2, adapter 4 and handle 3 are separate parts, wherein the razor head 2 can be connected to the adapter 4 on one side, and the handle 3 can be connected to the adapter 4 on the opposite side.

[0035] Figure 2 A front view of a razor head according to an embodiment of the present disclosure is shown. The razor head housing may include one or more housing portions, particularly a front housing portion and a rear housing portion, wherein blades 5 (five razor blades in the illustrated embodiment) are contained within the housing.

[0036] Figure 3An adapter 4 according to one embodiment of the present disclosure is shown. As mentioned, the adapter 4 is designed to connect to the razor head 2 and to the handle 3. The razor head is rotatable relative to the adapter about a (virtual) razor head axis 6, which is defined by a connecting element between the adapter and the razor head, as will be explained in more detail below. According to the present disclosure, a razor head biasing member 7 is arranged within the adapter, wherein an actuator element 8 of the biasing member 7 protrudes outside the adapter to engage the surface of the razor head. This facilitates manufacturing and installation.

[0037] Figure 4a A cross-section through a portion of the shaver head 2, adapter 4, and handle 3 according to an embodiment of the present disclosure is shown. The shaver head biasing component 7 includes a compression spring element 9 and an actuator element 8 for pushing the shaver head 2 into a rest position. The rest position of the shaver head 2 can be defined as the maximum rotational position of the shaver head relative to the adapter 4. When the shaver head 2 is mounted on the adapter 4, the actuator element 8 engages a surface or portion of the shaver head 2. When the handle remains stationary, the shaver head 2 can rotate about a shaver head axis 6 at least up to 20 degrees, particularly from 0 degrees to 40 degrees (where 0 degrees corresponds to the rest position of the shaver head and 40 degrees corresponds to the fully pivoted position of the shaver head), the shaver head axis being perpendicular or substantially perpendicular to the handle centroidal axis 10 extending along the handle 3. When the shaver head 2 rotates away from the rest position (in Figure 2 (In the clockwise direction), especially when the user moves the shaver head along the curved surface of the skin, the compression spring 9 of the shaver head biasing component is compressed.

[0038] Adapter 4 extends from handle end 4a to head end 4b, wherein adapter 4 includes an opening 11 extending from head end 4b to an internal portion of the adapter, and wherein shaver head biasing component 7 is mounted within said opening 11 of adapter 4. This facilitates mounting shaver head biasing component 4 to or within adapter 4. Furthermore, the main components of shaver head biasing component, particularly spring element 7, remain clean during use and are less affected by shaving foam that could negatively impact the function of the spring element.

[0039] The adapter opening 11 may have one or more first protrusions 14 on the side of the adapter designed to connect to the shaver head 2, wherein the pusher element 8 has one or more stop elements 15 for engaging the one or more first protrusions 14, preventing the pusher element from extending outward from the adapter beyond its maximum extension range. This feature also facilitates the mounting of the shaver head biasing component within the adapter. Figure 4bAs shown, the first protrusion 14 and the stop element 15 of the adapter may be additionally or alternatively arranged on the two lateral sides within the opening 11. The adapter may have a surface 15' inclined relative to the axis of the opening at one end of the opening 11 to facilitate the installation of the pusher element into the opening. In this example, each stop element 15 is provided with an inclined surface 15' such that when the pusher element is inserted into the opening 11, the engagement of the inclined surface and the stop element will push the corresponding first protrusion 14 slightly outward.

[0040] The adapter may also include at least one opening 12 extending from the handle end 4a into the interior portion of the adapter 4. The opening 12 of the adapter may have at least one third protrusion 13 for engaging the handle.

Figure 9 Thus, the one or more arcuate elements 17 of the adapter can be held between the one or more first arcuate elements 18 of the shaver head and the one or more second arcuate elements 19 of the shaver head.

[0046] The one or more concave surfaces of the one or more adapter arcuate elements 17 and the one or more convex surfaces of the one or more first arcuate elements 18 of the shaver head may correspond to a portion of the surface of a cylindrical tube having a first radius of curvature. Furthermore, the one or more concave surfaces of the one or more adapter arcuate elements 17 and the one or more convex surfaces of the one or more second arcuate elements 19 of the shaver head may correspond to a portion of the surface of a cylindrical tube having a second radius of curvature, wherein the first radius of curvature is smaller than the second radius of curvature. Specifically, the first radius of curvature is in the range of 2 to 8 mm, more specifically in the range of 3 to 5 mm, and wherein the second radius of curvature is in the range of 5 to 10 mm, more specifically in the range of 4 to 8 mm.

[0047] Furthermore, the one or more arcuate elements 17 of the adapter may have one or more second protrusions 20 for engaging one or more stop elements 21 of the shaver housing. Specifically, the one or more arcuate elements 17 of the adapter may have one or more second protrusions 20 on their concave surfaces for engaging one or more stop elements 21, the stop elements being arranged adjacent to or integrally formed at the one or more second arcuate elements 19 of the shaver head. When the shaver head is in a stationary position, the one or more second protrusions 20 of the one or more arcuate elements of the adapter can engage the one or more stop elements 21 of the shaver housing.

[0048] According to this disclosure, the razor head 2 can be connected to the handle 3 via an adapter 4. The handle may include a tongue or extension 22 adapted to be received within an opening 12 of the adapter, wherein the tongue or extension 22 of the handle is adapted to be slidably received within the opening of the adapter. Furthermore, the handle and the adapter may be designed to be connected via a snap-fit ​​connection (see [link to relevant documentation]). Figure 4a The third protrusion 13) is connected. Figure 10 The rear view of adapter 4, which shows port 12, can be seen in the image.

[0049] The handle 3 may include an annular element 23, which can be actuated or rotated at least partially about the axis of the handle to release the connection between the handle 3 and the adapter 4. The annular element 23 may be biased in a rest position to hold the adapter in a locked state relative to the handle.

[0050] As already mentioned, the adapter 4 may include one or more third protrusions 13 on one side of the handle, wherein the one or more third protrusions 13 may be arranged within a recess of the adapter. The annular element may include one or more engaging elements for engaging the one or more third protrusions of the adapter to hold the adapter in a locked state relative to the handle. The one or more engaging elements may be disengaged from the one or more third protrusions of the adapter by actuation or rotation of the annular element.
