AI Technical Summary
Existing shaving devices have coupling mechanisms that cannot effectively maintain the engagement between the razor holder and the handle when force is applied, leading to unintentional disengagement.
The design employs a connection mechanism that includes a first connecting element, a second connecting element, and a stopper. Through the cooperation of the pivot axis, ramp, and actuator, reliable engagement and disengagement of the razor holder and the handle are achieved. The stopper is used to prevent or release the pivoting of the first connecting element at different positions to ensure a stable connection.
This effectively prevents the razor holder from accidentally detaching from the handle, improving the stability and convenience of using the shaving device.

[0010] According to aspects of this disclosure, the second connecting element may include a ramp, and movement of the actuator along the ramp may cause the second connecting element to move in a first direction from a first position toward a second position.
[0011] According to aspects of this disclosure, when the second connecting element is moving in a first direction, one or more second engaging surfaces may contact one or more first engaging surfaces and apply force to the one or more first engaging surfaces.
[0012] According to aspects of this disclosure, the application of force on one or more first mating surfaces can cause one or more connecting members to pivot and cause the peripheral attachment portion to move inward.
[0013] According to aspects of this disclosure, the third connecting element may be configured to be arranged in a stacked relationship with the first connecting element and the second connecting element.
[0014] According to aspects of this disclosure, the first connecting element may be configured to pivot along the surface of the third connecting element.
[0015] According to aspects of this disclosure, the second connecting element may be biased toward the first position via a biasing component.
[0016] According to aspects of this disclosure, the stop may be included on the second connecting element.
[0017] According to aspects of this disclosure, the first connecting element may include a pair of opposing connecting parts.
[0018] According to aspects of this disclosure, one or more second engagement surfaces may be protrusions extending from the second coupling element.
[0019] According to aspects of this disclosure, a shaving device may include a coupling mechanism according to any aspect described above.

[0033] Reference Figures 1 to 7DEmbodiments of the coupling mechanism according to aspects of this disclosure are described, wherein similar numbers denote similar parts and will generally be referred to by reference number 10. While the coupling mechanism 10 is described with reference to specific examples, it should be understood that modifications and changes may be made to these examples without departing from the general scope as defined by the claims. Specifically, individual features of the various embodiments shown and / or mentioned herein may be combined in additional embodiments. Therefore, the specification and drawings should be considered in an illustrative rather than restrictive sense. The figures, not necessarily drawn to scale, depict illustrative aspects and are not intended to limit the scope of this disclosure. The depicted illustrative aspects are intended to be exemplary only.
[0034] The term "exemplary" is used in the sense of "example" rather than "ideal." While aspects of this disclosure allow for various modifications and alternatives, details thereof have been shown in the drawings by way of example and will be described in detail. However, it should be understood that this disclosure is not intended to limit aspects of the particular embodiments described. Rather, this disclosure is intended to cover all modifications, equivalents, and alternatives that fall within the scope of this disclosure.
[0035] Various materials, construction methods, and fastening methods will be discussed in the context of the disclosed embodiments. Those skilled in the art will recognize known alternatives to the materials, construction methods, and fastening methods, all of which are considered compatible with the disclosed embodiments and are intended to be covered by the appended claims.
[0036] As used in this disclosure and the appended claims, unless otherwise expressly stated, the singular forms “a / an” and “the” include plural indicators. As used in this disclosure and the appended claims, unless otherwise expressly stated, the term “or” is generally used in its sense of including “and / or”.
[0037] Throughout the description including the claims, unless otherwise stated, the terms "comprising one," "containing one," and "having one" shall be construed as synonymous with "comprising one or more," "containing one or more," and "having one or more." Furthermore, unless otherwise stated, any scope set forth in this specification, including the claims, shall be construed as encompassing its extreme values. Specific values of the described elements shall be construed as being within acceptable manufacturing or industry tolerances known to a person skilled in the art, and any use of the terms "substantially," "generally," and "typically" shall be construed as meaning falling within such acceptable tolerances.
[0038] When an element or feature is referred to herein as “on another element or feature,” “joined to,” “connected to,” or “linked to” another element or feature, it may be directly on, joined to, connected to, or linked to the other element or feature, or there may be intermediate elements or features present. Conversely, when an element or feature is referred to as “directly” on another element or feature, “directly joined to,” “directly connected to,” or “directly linked to” another element or feature, there may be no intermediate elements or features present. Other terms used to describe relationships between elements or features should be interpreted in a similar manner (e.g., “between” vs. “directly between,” “adjacent” vs. “directly adjacent,” etc.).
[0039] For ease of description, spatial relative terms such as “top,” “bottom,” “middle,” “inner,” “outer,” “below,” “below,” “lower,” “above,” and “upper” are used herein to describe the relationship between one element or feature and another element or feature illustrated in the diagrams. In addition to the orientation depicted in the diagrams, spatial relative terms may also be intended to cover different orientations of the device during use or operation. For example, if the device in the diagrams is flipped over, an element described as “below” or “below” other elements or features will be oriented as “above” other elements or features. Therefore, the example term “below” can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or rotated in other orientations), and the spatial relative descriptions used herein shall be interpreted accordingly.
[0040] While the terms “first,” “second,” etc., may be used herein to describe various elements, components, regions, layers, segments, and / or parameters, these elements, components, regions, layers, segments, and / or parameters should not be limited by these terms. These terms are used only to distinguish one element, component, region, layer, or segment from another region, layer, or segment. Therefore, without departing from the teachings of this disclosure, a first element, component, region, layer, or segment discussed herein may be referred to as a second element, component, region, layer, or segment.
[0041] like Figures 1 to 2 As shown, the coupling mechanism 10 can be configured to connect to a product, such as a handheld shaver (hereinafter "product") 100 having a head / replaceable shaver holder 102 and a handle 104. The coupling mechanism 10 may be contained within a housing 106 of the handle 104. The housing 106 may be directly connected to the handle 104. It is also contemplated that the housing 106 may be indirectly connected to the handle 104. Additionally, it is contemplated that the housing 106 may be integral with the handle 104. Figures 3 to 5As shown, the coupling mechanism 10 can be divided equally by an axis AA and includes a first coupling element 20, a second coupling element 40, a third coupling element 60, and an actuator 80. These are configured to allow engagement and disengagement of the razor holder 102 from the handle 104, while also improving the retention of the razor holder 102 to the handle 104 to prevent unintentional disengagement. The first coupling element 20, the second coupling element 40, and the third coupling element 60 can be configured to be arranged in a stacked relationship. In this arrangement, the second coupling element 40 may engage between and be completely surrounded by the first coupling elements 20, and the first coupling elements 20 and 40 may be supported on and / or within the third coupling element 60. In the disclosed embodiment, the coupling mechanism 10 may be attached to the housing 106 of the handle 104. It is contemplated that the coupling mechanism 10 may be attached to the handle 104 via an attachment connection, such as a snap-fit or press-fit connection.
[0042] like Figure 3 As shown, the first connecting element 20 may include one or more resiliently deformable connecting members (arms) 22 extending from the root 24. In the disclosed embodiment, the first connecting element 20 may include a pair of opposing connecting members 22 extending from the root 24. The root 24 may be radially and / or U-shaped to facilitate movement and / or pivoting of the connecting members 22. The terms “pivot” and “pivoting” as used herein may encompass movement, such as rotation, relative to a fixed point. Each connecting member 22 may include a peripheral attachment portion 26 configured to be received and held within the shaver holder 102 of the product 100. Due to the pivoting of the connecting members 22, each connecting member 22 and therefore each peripheral attachment portion 26 may be able to transition between an unretracted position and a retracted position, in which each peripheral attachment portion 26 may be held in the shaver holder 102, and in which the peripheral attachment portion 26 may no longer be held in the shaver holder 102. Each peripheral attachment portion 26 may extend outward to an attachment surface 28, which may be the outermost surface of each connecting member 22 and the connecting mechanism 10. For consideration, the terms "outward," "outwardly," and "outermost" as used herein may be understood to mean a direction away from and / or further away from axis AA. The attachment surface 28 of the peripheral attachment portion 26 may be arcuate. In the non-retracted position of the peripheral attachment portion 26 (see...), Figure 5 and Figure 7A Each attachment surface 28 may be located at a first distance D1 from each other. In the disclosed embodiment, the first distance D1 may be in the range of 21 mm to 23 mm, but most specifically may be 22 mm ± 0.1 mm. In the retracted position of the peripheral attachment portion 26 (see... Figure 7DThe first distance D1 between each attachment surface 28 may be less than 20 mm, specifically in the range of 18 mm to 20 mm, but most specifically 19.8 mm ± 0.1 mm.
[0043] like Figures 3 to 4 and Figures 7A to 7D As described, the first connecting element 20 may include arcuate pivot surfaces 30, 32 configured to pivot abut against complementary arcuate pivot surfaces 66, 68 of the third connecting element 60. In the disclosed embodiment, the pivot surfaces 30, 32 of each connecting member 22 may include an outer pivot surface 30 having a recessed radial geometry, the outer pivot surface being configured to pivot abut against a first complementary radial surface 66 of the third connecting element 60. The pivot surfaces 30, 32 of each connecting member 22 may also include an inner pivot surface 32 having a convex radial geometry, the inner pivot surface being configured to pivot abut against a second complementary radial surface 68 of the third connecting element 60. Figure 5 As shown, each connecting component 22 and therefore the first connecting element 20 can each pivot about a separate axis A. PA A PB Pivoting. Each pivot axis A PA A PB It may be located outside the connecting mechanism 10. For consideration, the term "external" as used herein may be understood to mean a location outside the sidewall 64 of the third connecting element 60. Pivot axis A PA A PB They can be spaced apart by a second distance D2. The second distance D2 can be greater than the first distance D1. In the disclosed embodiment, the second distance D2 can be in the range of 26 mm and 32 mm, but most specifically it can be 26.4 mm ± 0.1 mm. Thus, each attachment surface 28 and therefore each peripheral attachment portion 26 can be separated from each corresponding pivot axis A. PA A PB Offset inward. For consideration purposes, the terms “inward” and “inwardly” as used herein can be understood to mean in a direction toward and / or closer to axis AA. In the disclosed embodiments, the third distance D3, corresponding to the difference between distance D1 and each distance D2, can be in the range of 1 mm to 5 mm, but most specifically, it can be 2.2 mm ± 0.1 mm. When the user attempts to forcefully pull the shaver holder 102 out of the handle 104, it can generate torque on each connecting member 22. Torque can be applied to the outermost surface of the first connecting element 20, i.e., the attachment surface 28. Thus, due to each pivot axis A... PA A PBThe attachment surface 28 can be offset outward by a third distance D3, so that the torque tends to push each connecting part 22 outward and does not allow each connecting part 22 to retract, thereby maintaining the outer attachment portion 26 within the shaver holder 102 and thus maintaining the engagement between the shaver holder 102 and the handle 104.
[0044] Each connecting member 22 may include a first engaging surface 34 and a second engaging surface 36 configured to engage and disengage surfaces 52, 58 included on the second connecting element 40. In the disclosed embodiment, the first connecting element 20 may include a pair of opposing first engaging surfaces 34 and a pair of opposing second engaging surfaces 36. Each first engaging surface 34 may act as a cam surface through which energy is received from the surface 52 of the second connecting element 40. Each first engaging surface 34 and each second engaging surface 36 may project inward toward axis AA. Each first engaging surface 34 may be positioned between the second engaging surface 36 and the root 24. When each second engaging surface 36 engages with the complementary surface 58 of the second connecting element 40, unintentional disengagement of the razor holder 102 from the handle 104 is prevented because each connecting member 22 is then prevented from pivoting inward. When each second engaging surface 36 disengages from the complementary surface 58 of the second connecting element 40, disengagement of the razor holder 102 from the handle 104 is no longer prevented. Additionally, the first connecting element 22 may include a gap 38 extending from the first engagement surface 34 of the first connecting element 20 to the root 24. The gap 38 allows the second connecting element 40 to move between the first connecting elements 20.
[0045] like Figure 3 As shown, the second connecting element 40 may be configured to be positioned inside the first connecting element 20. The second connecting element 40 may include a pair of arms 42 extending from the base 44. A ramp 46 may extend from the base 44 of the second connecting element 40. The ramp 46 may be configured to engage an actuator 80 to cause movement of the second connecting element 40. One or more gaps 48, 50 may be defined between the arms 42 of the second connecting element 40 for receiving the biasing member 90 and / or the assembly 70 of the third connecting element 60. In the disclosed embodiment, the first gap 48 and the second gap 50 may be defined between the arms 42 of the second connecting element 40. The first gap 48 may be defined between the engagement surface of the second connecting element 40 and the stops 52, 58 (discussed below). The second gap 50 may be defined between the wall 56 of the second connecting element 40 and the base 44 of the second connecting element 40. The wall 56 of the second connecting element 40 may extend transversely to the axis AA.
[0046] The second connecting element 40 may include one or more engagement surfaces (second engagement surfaces) (protrusions) 52, said one or more engagement surfaces being configured to contact a corresponding first engagement surface 34 of a corresponding connecting member 22 of the first connecting element 20 and to apply a first force to said corresponding first engagement surface. In the disclosed embodiment, the second connecting element 40 includes a pair of engagement surfaces 52. Each engagement surface 52 of the second connecting element 40 may extend perpendicular to axis AA. Each engagement surface 52 may extend from a corresponding arm 42 of the second connecting element 40. A wall 56 of the second connecting element 40 may be located between the engagement surfaces 52 of the second connecting element 40 and the base 44 of the second connecting element 40. The second connecting element 40 may also include one or more stops 58 extending transversely to axis AA. In the disclosed embodiment, the second connecting element 40 may include a pair of opposing stops 58. Each stop 58 may extend from a corresponding arm 42 of the second connecting element 40. Each stop 58 may be positioned inside a corresponding second engagement surface 36 of each connecting member 22 of the first connecting element 20. As discussed above, each stop 58 can be configured to engage and disengage from each corresponding second engagement surface 36 of each corresponding connecting member 22. When each stop 58 engages with the corresponding second engagement surface 36 of the first connecting element 20, pivoting of each connecting member 22 is impeded, thereby further maintaining the retention of the peripheral attachment portion 26 within the shaver holder 102. When each stop 58 disengages from the corresponding second engagement surface 36 of the first connecting element 20, pivoting of each connecting member 22 is no longer impeded, thereby allowing detachment of the shaver holder 102 from the handle 104.
[0047] As by Figures 7A to 7D As described, the second connecting element 40 may be able to move from a first position to a second position in a first direction d1 and from a second position to a first position in a second direction d2. In the disclosed embodiment, the movement of the second connecting element 40 in the first direction d1 may be toward the root 24 of the first connecting element 20, and the movement of the second connecting element 40 in the second direction d2 may be toward the peripheral attachment portion 26 of the first connecting element 20. Consideredly, the first position of the second connecting element 40 may be a stationary position, wherein the stop 58 of the second connecting element 40 may engage with the second engagement surface 36 of the first connecting element 20, such that pivoting of the connecting member 22 can be prevented (see...). Figure 7A Furthermore, the peripheral attachment portion 26 can be in the non-retracted position and retained within the shaver holder 102. Consideration is given to the second position of the second connecting element 40, in which the stop 58 of the second connecting element 40 can disengage from the second engagement surface 36 of the first connecting element 20, such that pivoting of the connecting member 22 is no longer prevented, and the peripheral attachment portion 26 can be in the retracted position and no longer retained within the shaver holder 102 (see...). Figures 7C to 7D Alternatively, the second position of the second connecting element 40 may correspond to the disengaged position of the shaver holder in which the actuator 90 is fully pressed. The second connecting element 40 may be biased toward the first position by a biasing member 90. In the disclosed embodiment, the biasing member 90 may be a coil spring. The biasing member 90 may be fastened between the wall 56 of the second connecting element 40 and the wall 70 of the third connecting element 60. The wall 70 of the third connecting element 60 may extend through the second gap 50 of the second connecting element 40. The second connecting element 40 may be movable between the connecting members 22 of the first connecting element 20 in a first direction d1 and a second direction d2.
[0048] like Figures 6A to 6B As shown, movement of the second connecting element 40 can be caused by an actuator 80 of the connecting mechanism 10. In the disclosed embodiment, the actuator 80 is a push-button actuator. The actuator 80 may be positioned above the second connecting element 40. The actuator 80 may include a pin 82 extending perpendicular to axis AA toward the second connecting element 40. The pin 82 of the actuator 80 may be configured to move toward the second connecting element 40 when the actuator is pressed by a user. The pin 82 of the actuator 80 may contact and push the ramp 46 of the second connecting element 40 by applying a force to the ramp 46 when pressed by the user. The application of force may cause the pin 82 to slide along the ramp 46 in a second direction d2 (see [link to documentation]). Figure 6B Return to reference. Figures 7A to 7D Sliding along ramp 46 in the second direction d2 causes the second connecting element 40 to compress the biasing member 90 and move toward the second position in the first direction d1 (see...). Figures 7A to 7B Movement toward the second position in the first direction d1 causes each stop 58 of the second connecting element 40 to no longer engage each of the second engagement surfaces 36 of the first connecting element 20 and no longer impede the pivoting of the connecting member 22 of the first connecting element 20 (see...). Figures 7B to 7D The movement toward the second position in the first direction d1 can also cause the first engagement surface 52 of the second connecting element 40 to engage the first engagement surface 34 of the first connecting element 20 and apply force to the first engagement surface 34 of the first connecting element 20 (see...). Figures 7B to 7D The application of force via the first engagement surface 52 of the second connecting element 40 on the first engagement surface 34 of the first connecting element 20 can push the first engagement surface 34 of the first connecting element 20 in the first direction d1. Pushing the first engagement surface 34 of the first connecting element 20 in the first direction d1 can cause each connecting member 22 and therefore each peripheral attachment portion 26 to revolve around each corresponding pivot axis A. PA A PBThe shaver head is pivoted inward toward axis AA, thereby removing the retainer within the shaver holder 102. In this manner, the coupling mechanism 10 allows the shaver holder 102 to be detached from the handle 104.
[0049] like Figure 3 As shown, the third connecting element 60 may include a frame 62 configured to receive and support the first connecting element 20 and the second connecting element 40. A wall 70 of the third connecting element 60 may extend from the frame 62. The third connecting element 60 may include a pair of axially extending sidewalls 64. Each sidewall 64 may include a first inner pivot surface 66 complementary to the outer pivot surface 30 of the first connecting element 20. In the disclosed embodiment, each first inner pivot surface 66 may include a convex radial geometry complementary to the outer pivot surface 30 of the first connecting element 20. The third connecting element 60 may also include a second inner pivot surface 68, which may include a concave radial geometry complementary to the inner pivot surface 32 of the first connecting element 20. Each first engagement surface 34 of the first connecting element 20 may extend toward the axis AA above the second inner pivot surface 68 of the third connecting element 60, such that pivoting of the connecting member 22 is not obstructed by the second inner pivot surface 68.
