Description

Technical Field

[0001] This disclosure relates to a razor handle and a razor assembly including the razor handle, and more specifically, to a razor handle including a plunger and a razor assembly including the razor handle. Background Technology

[0002] Generally, a razor is a product used to shave facial or body hair, including a razor handle for holding and a razor blade holder with razor blades that come into contact with the skin for shaving.

[0003] To allow the razor blade holder to closely conform to the contours of the skin, the razor blade holder is pivotally connected to the razor handle.

[0004] When the razor handle and the razor blade holder are fully aligned and connected without misalignment, the razor blade holder can pivot stably relative to the razor handle, thus efficiently cutting the user's body hair. Conversely, when the razor handle and the razor blade holder are misaligned and not fully connected, the razor blade holder may easily separate from the razor handle due to slight impact or external force, or pivot unstablely in this state.

[0005] If a user notices that the razor handle and the razor blade holder are misaligned, they can separate the razor handle from the razor blade holder and realign them before using the razor.

[0006] On the other hand, if a user shaves without noticing that the razor handle and the razor blade holder are misaligned, the unstable pivoting of the razor blade holder may result in inefficient hair cutting or injury to the user from the razor blades. Summary of the Invention

[0037] The advantages and features of this disclosure, as well as the methods for achieving these advantages and features, will become more apparent from the embodiments described in detail with reference to the accompanying drawings. However, this disclosure is not limited to the disclosed embodiments, but can be implemented in many different ways. These embodiments are only intended to improve this disclosure and to enable those skilled in the art to fully understand its scope. This disclosure is defined by the scope of the claims.

[0038] Furthermore, embodiments of this disclosure will be described in conjunction with sectional views and / or schematic diagrams as idealized exemplary illustrations. Therefore, the shapes shown in the figures may vary depending on manufacturing processes, tolerances, etc. Additionally, for ease of explanation, the constituent elements in the figures may be relatively enlarged or reduced. Throughout the figures, the same reference numerals denote the same constituent elements.

[0039] The razor handle and razor assembly including the razor handle according to embodiments of the present disclosure will now be described with reference to the accompanying drawings.

[0040] Figure 1 This is a schematic diagram showing the connection state between the razor handle and the razor blade holder according to an embodiment of the present disclosure.

[0041] Reference Figure 1 In this embodiment, the razor handle 10 is connected to the razor blade holder 20 and includes a grip portion 1100 and a head 100. The grip portion 1100 is the part that the user can hold and constitutes the main body of the razor handle 10. The head 100 is capable of pivotally supporting the razor blade holder 20 (see [link to relevant documentation]). Figure 2 (and the part that can be detachably connected to the razor blade holder 20.)

[0042] Figure 2 This is a bottom view showing the detached state of the razor handle in its installed state according to an embodiment of the present disclosure.

[0043] The razor handle 10 can be connected to the razor blade holder 20. First, the razor blade holder 20 will be described.

[0044] The razor blade holder 20 can accommodate at least one razor blade 230. The razor blade holder 20 may include: a cam 210 for contacting a cam contact portion 115 (described later) of the plunger 110; a connector 220 for connection to a blade holder assembly portion 140 (described later) of the head 100; a clip 250 for securing the razor blade; a lubricating band (not shown) for applying lubricant to the skin; and a protector (not shown) for close contact with and pulling on the user's skin. The razor blade holder 20 is rotatable relative to the razor handle 10 by a first axis of rotation AX1 (see...). Figure 3The first rotation axis AX1 is the axis that runs longitudinally through the connecting member 220. It can be a fixed axis or an axis that can move within a certain range. The longitudinal direction refers to the length direction of the razor blade holder 20, which is parallel to the x-axis in the attached figure. The transverse direction is the width direction of the razor blade holder 20, which is perpendicular to the longitudinal direction (i.e., the x-axis direction) and parallel to the y-axis direction in the attached figure.

[0045] The grip part 1100 is the part that the user can hold. The grip part 1100 can be connected to the head 100.

[0046] The head 100 is the portion connected to the razor blade holder 20 and pivotally supports the connected razor blade holder 20. The head 100 can be detachably connected to the razor blade holder 20 and pivotally supports the razor blade holder 20 within a certain angular range relative to the first rotation axis AX1. The head 100 may include a plunger 110, a plunger housing 120, a blade holder coupling portion 140, and an operating portion 130.

[0047] The plunger 110 elastically supports the razor blade holder 20 and provides a restoring force to return the razor blade holder 20 to a neutral position. The plunger 110 may be supported by an elastic member (not shown) to provide the restoring force. The plunger 110 may include a cam contact portion 115 that contacts a cam 210 of the razor blade holder 20. The shape of the cam contact portion 115 may be configured to interact with the shape of the cam 210, thereby defining the pivoting motion of the razor blade holder 20 relative to the razor handle 10. The cam contact portion 115 may be formed at a position corresponding to the position of the cam 210. When the cam 210 is near the center portion formed on the lower surface of the razor blade holder 20, the cam contact portion 115 may be near the center portion formed on the outer surface of the plunger 110. The cam contact portion 115 may be formed in a recessed or raised shape on the outer surface of the plunger 110, or it may be formed on the same plane as the outer surface of the plunger 110.

[0048] When the razor blade holder 20 pivots, the plunger 110 can slide along a first direction DR1. The first direction DR1 is the direction towards the head 100 with reference to the razor blade holder 20. The plunger 110, which slides along the first direction DR1, is supported by an elastic member, thereby providing a restoring force in a second direction DR2 opposite to the first direction DR1, so that the razor blade holder 20 returns to a neutral position. As the razor blade holder 20 pivots, the plunger 110 provides a restoring force to the razor blade holder 20 in the second direction DR2 while sliding along the first direction DR1.

[0049] The plunger 110 may be configured to be slidably supported by the plunger housing 120. The shape of the plunger 110, which can be slidably supported by the plunger housing 120, will be described in the following description of the plunger housing 120.

[0050] An indicator 111 may be provided on the outer surface of the plunger 110. The outer surface of the plunger 110 refers to the surface facing the same space as the lower surface of the razor blade holder 20, and at least a portion of the outer surface of the plunger 110 may be exposed to the outside along with the lower surface of the razor blade holder 20 when observing the lower surface of the razor blade holder 20. The outer surface of the plunger 110 may be formed to have a predetermined area so that the user can easily confirm the indicator 111. For example, the indicator 111 may be formed to have a dimension in the longitudinal direction (i.e., the x-axis direction) that is larger than the dimension of the cam 210 in the longitudinal direction (i.e., the x-axis direction).

[0051] Furthermore, when the blade holder assembly 140 is connected to the connector 220, the ratio of the longitudinal width of the plunger 110 to the outermost distance between the outermost side of the other end of the first arm 141 and the outermost side of the other end of the second arm 142 in the longitudinal direction can be 0.8 to 1.2.

[0052] The plunger 110 is formed to be relatively long in the longitudinal direction (i.e., the x-axis direction) along which the shaving blade 230 of the razor blade holder 20 extends, and is arranged over a considerable portion of the longitudinal (i.e., x-axis direction) length of the razor blade holder 20. Therefore, the outer surface of the plunger 110 according to this disclosure can have a larger area than conventional plungers. Consequently, an indicator 111 with a relatively large size and area, easily identifiable by the user's naked eye, can be provided on the outer surface of the plunger 110.

[0053] An indicator 111, used to indicate at least one of the mounting and pivoting states of the razor blade holder 20, may be disposed on the outer surface of the plunger 110. The indicator 111 may be provided on the outer surface of the plunger 110 in various forms, such as engraving, protrusion, sticker, or stamp. The indicator 111 may be formed into various shapes that are recognizable to the user, such as straight lines, circles, and polygons, and its shape is not limited. Furthermore, the indicator 111 may be formed to have a different color than the outer surface of the plunger 110.

[0054] The exposed area, shape, position, etc. of the indicator 111 can change according to the installation state and pivoting state of the razor blade holder 20, so the indicator 111 can indicate the installation state and pivoting state of the razor blade holder 20.

[0055] First, the installation state and pivoting state of the razor blade holder 20 are defined. The installation state refers to whether the razor blade holder 20 is installed to the razor handle 10. The installation state can include a separated state and a connected state. In the installation state, the separated state means that the razor blade holder 20 is not connected to the razor handle 10, and the connected state means that the razor blade holder 20 is connected to the razor handle 10. Specifically, the connected state means that the razor blade holder 20 is not subjected to any individual external force when connected to the razor handle 10.

[0056] The pivoting state refers to the state in which the razor blade holder 20, while connected to the razor handle 10, pivots within a certain angular range around the first rotation axis AX1. The pivoting state can include a neutral state, a maximum pivoting state, and a partial pivoting state.

[0057] The neutral state refers to the state where no individual external force is applied to the razor blade holder 20, or the pivoted razor blade holder 20 is returned to the neutral position by the plunger 110 providing the restoring force. The maximum pivot state refers to the state where the razor blade holder 20 pivots from the neutral position to its maximum angle. The partial pivot state refers to the state where the razor blade holder 20 pivots from the neutral position to a angle less than the maximum angle. The neutral state in the pivot state and the connected state in the installed state refer to the neutral position of the razor blade holder 20, but for ease of explanation, the neutral position in the pivot state is called the neutral state, and the neutral position in the installed state is called the connected state.

[0058] Figure 3 This is a bottom view showing the connected state of the razor handle according to this disclosure.

[0059] Reference Figure 2 and Figure 3 The area of ​​the indicator 111 exposed to the outside differs depending on whether the razor blade holder 20 is in a detached or connected state. For example, in the detached state, the area of ​​the indicator 111 may be fully exposed, while in the connected state, the area of ​​the indicator 111 may be partially exposed.

[0060] According to another embodiment, even in the separated state, it can be as follows: Figure 3 As shown in the example, a portion of the indicator 111 is housed within the plunger housing 120, while another portion of the indicator 111 is exposed to the outside. In this case, the area of ​​the indicator 111 exposed to the outside in the connected state can be smaller than the area exposed to the outside in the disconnected state.

[0061] Ultimately, the detached and connected states of the razor blade holder 20 can be distinguished based on the size of the area of ​​the indicator 111 exposed to the outside.

[0062] Furthermore, in both the shaver blade holder's detached and connected states, at least a portion of the exposed parts of the indicator 111 can differ from each other. For example, refer to... Figure 2 and Figure 3 In the separated state, all of the indicator 111 is exposed, while in the connected state, a portion of the indicator 111 is exposed to the outside. Therefore, depending on whether the razor blade holder 20 is in the separated or connected state, the portions of the indicator 111 exposed to the outside can be different from each other.

[0063] According to another embodiment, even in the separated state, it can be as follows: Figure 3 As shown in the example, a portion of indicator 111 is housed within plunger housing 120, while another portion of indicator 111 is exposed to the outside. In this case, a portion of the externally exposed portion of indicator 111 in the disconnected state may not be exposed to the outside in the connected state.

[0064] According to one embodiment, the indicator 111 may be characterized in that the portion exposed to the outside in the separated state but not exposed to the outside in the connected state is visually clearly distinguishable. For example, the shape and / or color of the corresponding portion may differ from the other portions.

[0065] Users can distinguish between the separated state and the connected state by the whole or part of the part exposed in indicator 111.

[0066] Furthermore, the proximity of the front end of the indicator 111 to the grip portion 1100 differs between the detached and connected states of the razor blade holder 20. The front end of the indicator 111 refers to the portion of the indicator facing the razor blade holder 20 in the second direction DR2. In the connected state, the front end of the indicator 111 can be closer to the grip portion 1100 than in the detached state. In the connected state, the distance D2 between the front end of the indicator 111 and the grip portion 1100 can be smaller than the distance D1 between the front end of the indicator 111 and the grip portion 1100 in the detached state.

[0067] Additionally, the connection state of the razor blade holder 20 can include: an aligned connection state, where the connector 220 of the razor blade holder 20 is fully connected to the blade holder joint 140 of the head 100 without misalignment; or a misaligned connection state, where the connector 220 of the razor blade holder 20 is not fully connected to the blade holder joint 140 of the head 100 due to misalignment. The indicator 111 can indicate the aligned and misaligned connection states of the razor blade holder.

[0068] When the razor blade holder 20 and the razor handle 10 are in a misaligned connection state, the sliding distance of the plunger 110 on the longitudinally spaced side and the other side in the first direction DR1 may be different. In this case, the position of the indicator 111 formed on the outer surface of the plunger 110 may be different from the position of the indicator 111 in the aligned connection state. In the aligned connection state, the indicator 111 may be symmetrical with respect to the central axis in the longitudinal direction (i.e., the y-axis direction) of the plunger housing 120 or the razor handle 10, but in the misaligned connection state, the indicator 111 may be asymmetrical with respect to the central axis in the longitudinal direction of the plunger housing 120.

[0069] Therefore, the user can confirm the aligned and misaligned connection status between the razor blade holder 20 and the razor handle 10. When the user identifies a misaligned connection, they can re-attempt to connect the razor blade holder 20 to the razor handle 10. Whether the connection status between the razor blade holder 20 and the razor handle 10 is aligned or misaligned can be easily confirmed in the modified example of indicator 111 described later, and will therefore be described in detail again in the modified example of indicator 111.

[0070] Figure 4 This is a bottom view showing a partial pivoting state of the razor handle according to an embodiment of the present disclosure. Figure 5 It shows a ratio Figure 4 A bottom view of the further pivoted state. Figure 6 This is a bottom view showing the maximum pivoting state of the razor handle according to an embodiment of the present disclosure.

[0071] Reference Figures 4 to 6 The area of ​​the indicator 111 exposed to the outside differs depending on whether the razor blade holder 20 is in its maximum pivot state or partially pivot state. In the maximum pivot state, the exposed area of ​​the indicator 111 is minimal. In the partially pivot state, the exposed area of ​​the indicator 111 can be larger than that in the maximum pivot state.

[0072] Users can check the exposed area of ​​indicator 111 and adjust the pivot angle of razor blade holder 20 via a mirror during shaving, thus enabling effective shaving. (Refer to...) Figure 4 and Figure 5The partial pivoting state can be divided into multiple states based on the pivoting angle. For example, the partial pivoting state may include: a first partial pivoting state, in which the razor blade holder 20 pivots from a neutral position to a predetermined first pivoting angle; and a second partial pivoting state, in which the razor blade holder 20 pivots from a neutral position to a second pivoting angle greater than the first pivoting angle. In the first partial pivoting state, the exposed area of ​​the indicator 111 can be greater than that in the second partial pivoting state. Therefore, the user can confirm the pivoting angle or pivoting state of the razor blade holder 20 by the continuous increase or decrease of the exposed area of ​​the indicator 111.

[0073] Reference Figures 4 to 6 In the maximum pivot state and the partial pivot state of the razor blade holder 20, at least a portion of the exposed portion of the indicator 111 may be different from each other.

[0074] Reference Figure 4 and Figure 5 The comparison is made in the first part of the pivoting state (see Figure 4 ) and the second part of the pivot state (see Figure 5 In the first pivot state, the portion of indicator 111 exposed to the outside is different from the other. That is, the portion of indicator 111 exposed to the outside and adjacent to plunger housing 120 in the first pivot state is not exposed to the outside in the second pivot state.

[0075] Figure 4 and Figure 5 An example of an indicator 111 being triangular in shape is shown. However, according to an embodiment, the portion of the indicator 111 that is exposed to the outside in a first pivot state but not exposed to the outside in a second pivot state can be configured to be visually distinct from the other portions (e.g., based on non-uniformity in shape due to different colors, height differences / curvature changes, etc.) so that the user can easily identify the changes in the exposed portion of the indicator 111 according to the pivot state.

[0076] Similarly, refer to Figure 6 and Figure 4 and Figure 5 For comparison, at the maximum pivot state (see...) Figure 6 Part One Pivot State (see) Figure 4 ) and the second part of the pivot state (see Figure 5 Under these conditions, the areas of the indicator 111 exposed to the outside will differ from one another. That is, the portion of the indicator 111 that is exposed to the outside and adjacent to the plunger housing 120 in the first and second pivot states is not exposed to the outside in the maximum pivot state.

[0077] Figures 4 to 6An example of an indicator 111 being triangular in shape is shown. However, according to an embodiment, the portion of the indicator 111 that is exposed to the outside in the first and second pivot states but not exposed to the outside in the maximum pivot state can be configured to be visually distinct from other portions (e.g., based on non-uniformity in shape due to different colors, height differences / curvature changes, etc.) so that the user can easily identify changes in the exposed portion of the indicator 111 according to the pivot state.

[0078] The user can confirm the maximum pivoting state and partial pivoting state of the razor blade holder 20 by observing the difference in external exposure of the indicator 111. Similarly, the user can confirm the first partial pivoting state and the second partial pivoting state. Additionally, Figure 6 Indicator 111 is shown to be exposed to a minimum, but indicator 111 may also be completely hidden from the outside.

[0079] Furthermore, the proximity of the front end of the indicator 111 to the grip 1100 can vary depending on whether the razor blade holder 20 is in its maximum pivot state or partial pivot state. In the maximum pivot state, the front end of the indicator 111 can be closer to the grip 1100 than in the partial pivot state. (See reference...) Figures 4 to 6 In the maximum pivot state, the distance D5 between the front end of the indicator 111 and the grip 1100 can be smaller than the distances D3 and D4 between the front end of the indicator 111 and the grip 1100 in the partial pivot state.

[0080] Furthermore, compared to the first pivoting state, in the second pivoting state, which pivots at a larger angle, the front end of the indicator 111 is positioned closer to the grip portion 1100. (See reference...) Figures 3 to 5 In the second pivot state, the distance D4 between the front end of the indicator 111 and the grip portion 1100 can be less than the distance D3 between the front end of the indicator 111 and the grip portion 1100 in the first pivot state.

[0081] Furthermore, compared to the neutral state, in the partially pivoted state, the position of the front end of the indicator 111 can be closer to the grip portion 1100. In the partially pivoted state, the distances D3 and D4 between the front end of the indicator 111 and the grip portion 1100 can be smaller than the distance D2 between the front end of the indicator 111 and the grip portion 1100 in the neutral state.

[0082] Figure 7 This is a cross-sectional view of the head of a razor handle according to an embodiment of the present disclosure.

[0083] Reference Figure 7The plunger housing 120 can slidably support the plunger 110. The plunger housing 120 can be connected to the plunger 110 of the head 100. The plunger housing 120 can be connected to the head 100, or it can be integrally formed with other structures of the head 100.

[0084] When the head 100 further includes a plunger housing 120, the plunger 110 may include an upper wall portion 116, a first side wall portion 117, and a second side wall portion 118. The upper wall portion 116 is the portion where the indicator 111 is arranged, and the first side wall portion 117 and the second side wall portion 118 are portions extending downward from both sides of the upper wall portion 116, respectively. The plunger 110 may be supported by the guide sidewall 122 of the lower housing 121 (described later) to enable sliding.

[0085] The plunger housing 120 may include an upper housing 125 and a lower housing 121. The upper housing 125 and the lower housing 121 may form a space for receiving the plunger 110 and the resilient member. The upper housing 125 and the lower housing 121 may be interconnected. The lower housing 121 may include a pair of outer sidewalls 124 to form an internal space, a pair of guide sidewalls 122 to guide the sliding path of the plunger 110, and a support wall 123 to limit the range of rotation of the first arm 141 and the second arm 142 (described later).

[0086] The outer sidewall 124 is detachably inserted into a groove formed within the upper housing 125. Guide sidewalls 122 are spaced and protrude inwardly from the outer sidewall 124. A first sidewall portion 117 and a second sidewall portion 118 are respectively inserted into a pair of spaces formed between the pair of guide sidewalls 122 and the pair of outer sidewalls 124, allowing the plunger 110 to slide along a straight path. A support wall 123 supports the other end of the first arm 141 and the other end of the second arm 142, preventing the gap between the other ends of the first arm 141 and the second arm 142 from narrowing.

[0087] Reference Figure 2 and Figure 3 The proximity of the front end of the indicator 111 to the front end of the plunger housing 120 can vary depending on whether the razor blade holder 20 is in a separated or connected state. The front end of the plunger housing 120 refers to the portion of the plunger housing 120 facing the end of the razor blade holder 20 in the second direction DR2. Compared to the separated state, in the connected state, the front end of the indicator 111 can be closer to the front end of the plunger housing 120. In the connected state, the distance D7 between the front end of the indicator 111 and the front end of the plunger housing 120 can be smaller than the distance D6 between the front end of the indicator 111 and the front end of the plunger housing 120 in the separated state.

[0088] In addition, refer to Figure 2 and Figure 6In the disengaged state, the plunger 110 does not slide, so the indicator 111 can be entirely exposed to the outside of the plunger housing 120. Conversely, in the maximum pivoted state, the plunger 110 slides toward the plunger housing 120 along the first direction DR1, so at least a portion of the indicator 111 can be accommodated within the plunger housing 120.

[0089] Furthermore, in the disassembled state, a portion of the indicator 111 can be accommodated inside the plunger housing 120, and the area of ​​the unexposed portion of the indicator 111 can be smaller than the area of ​​the unexposed portion of the indicator 111 in the connected and pivoted states.

[0090] Reference Figures 4 to 6 The degree of proximity between the front end of the indicator 111 and the front end of the plunger housing 120 can vary depending on whether the razor blade holder 20 is in its maximum pivot state or a partial pivot state. In the maximum pivot state, the distance D10 between the front end of the indicator 111 and the front end of the plunger housing 120 can be less than the distances D8 and D9 between the front end of the indicator 111 and the front end of the plunger housing 120 in the partial pivot state.

[0091] The blade holder assembly 140 is detachably connected to the connector 220 of the razor blade holder 20. The blade holder assembly 140 may include a pair of first arms 141 and second arms 142 spaced apart longitudinally (i.e., along the x-axis) of the razor blades 230. The first arms 141 and second arms 142 are each pivotable about one end, causing their other ends to move apart or closer to each other longitudinally (i.e., along the x-axis). With the pivoting of the first arms 141 and second arms 142, a portion of the other end of each arm is inserted into the receiving space of the connector 220, thus enabling detachment. The connection portions of the first arms 141 and second arms 220, and the connection portions of the second arms 142 and second arms 220, can constitute a first rotation axis AX1 serving as the pivot center of the razor blade holder 20.

[0092] in addition, Figure 3 An example is shown where the connector 220 is formed in a position that does not overlap with the razor blade 230. However, according to an embodiment, the connector 220 may be formed on the lower surface of the razor blade holder 20 and overlap with at least a portion of the razor blade 230. In this case, the first rotation axis AX1 of the razor blade holder 20 (see...) Figure 3 It can be formed at a position different from the axis of the longitudinal through connector 220.

[0093] In addition to the pair of first arms 141 and second arms 142, the blade holder joint 140 can also be detachably connected to the connector 220 of the razor blade holder 20 by means of snap-fit ​​connection, hook connection, etc.

[0094] at the same time, Figure 3 An example is shown of a blade holder assembly 140, including a pair of first arms 141 and second arms 142, connected to a connector 220 fixed to a razor blade holder 20, but this disclosure is not limited to this example. For example, the connector 220 may be connected to the razor blade holder 20 and pivot about a first rotation axis AX1. In this case, the blade holder assembly 140 may be connected to the connector by a snap-fit ​​connection, a hook connection, or the like, without the need for a method including a pair of first arms 141 and second arms 142.

[0095] The operating section 130 is used to operate the first arm 141 and the second arm 142 of the blade holder assembly 140. The operating section 130 can disengage the connection between the first arm 141 and the connector 220, and the connection between the second arm 142 and the connector 220, thereby separating the razor blade holder 20 from the razor handle 10. When the operating section 130 moves along the first direction DR1, the distance between the other end of the first arm 141 and the other end of the second arm 142 decreases. As the distance between the other ends of the first arm 141 and the second arm 142 decreases, the other ends of the first arm 141 and the second arm 142 disengage from the receiving space of the connector 220, thereby releasing the connection between the first arm 141 and the connector 220, and the connection between the second arm 142 and the connector 220.

[0096] Figure 8 It is shown Figure 2 A bottom view of a modified embodiment of the indicator. For ease of explanation, the same reference numerals are used for parts similar to those in the foregoing embodiments, and descriptions of parts common to those in the foregoing embodiments are omitted.

[0097] Reference Figure 8 The indicator 112 may include a first portion 112a and a second portion 112b. The first portion 112a may be formed closer to the front end of the plunger housing 120 than the second portion 112b, and the second portion 112b may be formed closer to the razor blade holder 20 than the first portion 112a. The first portion 112a may be formed in a straight line shape or contain straight lines. For example, all or part of the first portion 112a may be formed as a longer straight line in the longitudinal direction (i.e., the x-axis direction), while the second portion 112b may be formed in a different shape than the first portion 112a, such as a circle or a polygon. Alternatively, all or part of the first portion 112a may have the same or corresponding shape as the front end of the plunger housing 120.

[0098] With the razor blade holder 20 in the detached state, all or part of the first part 112a and all of the second part 112b may be exposed to the outside of the plunger housing 120.

[0099] Figure 9 It is shown Figure 8 Bottom view of the razor handle in its connected state. Figure 10 It is shown that... Figure 9 Bottom view of different connection states.

[0100] Reference Figure 9 With the razor blade holder 20 in the connected state, at least a portion of the first part 112a may be located adjacent to the front end of the plunger housing 120.

[0101] In this case, the user can identify whether the razor blade holder 20 is properly connected based on whether the first part 112a is closer to the front end of the plunger housing 120 compared to the separated state.

[0102] For example, in the disassembled state, the first part 112a is arranged spaced apart from the front end of the plunger housing 120. However, during the connection process, the plunger 110 moves a certain distance along the first direction DR1, and in the normal connection state, at least a portion of the first part 112a is exposed to the outside in contact with the front end of the plunger housing 120, so that the user can identify whether the razor blade holder 20 is properly connected based on the relative position between the first part 112a and the plunger housing 120.

[0103] Alternatively, in both the disconnected and connected states, the first portion 112a is located adjacent to the front end of the plunger housing 120, or a portion of the first portion 112a is housed inside the plunger housing 120, but the exposed area of ​​the first portion 112a in the connected state is smaller than the exposed area of ​​the first portion 112a in the disconnected state.

[0104] Furthermore, when all or part of the first portion 112a is formed in a shape corresponding to the front end of the plunger housing 120, the user can identify whether the razor blade holder 20 is properly connected based on the degree of shape matching between the first portion 112a and the front end of the plunger housing 120.

[0105] In addition, refer to Figure 9 In the connected state, at least a portion of the first part 112a is located adjacent to the front end of the plunger housing 120, so that when the rotation angle of the razor blade holder 20 increases, the plunger 110 retracts along the first direction DR1. Furthermore, as the rotation angle of the razor blade holder 20 increases, the exposed area of ​​the first part 112a gradually decreases, and when the rotation angle of the razor blade holder 20 is greater than or equal to a certain angle, the first part 112a can be completely accommodated within the plunger housing 120. For example, when the razor blade holder 20 reaches its maximum rotation angle, the first part 112a can be completely accommodated within the plunger housing 120.

[0106] Therefore, the user can identify the degree of rotation of the razor blade holder 20 based on the exposed area of ​​the first part 112a.

[0107] That is, the first part 112a can serve as an indicator for indicating whether the razor blade holder 20 is connected and / or as an indicator for indicating the degree of rotation of the razor blade holder 20. In addition, the second part 112b can serve as an indicator for indicating the degree of rotation of the razor blade holder 20.

[0108] Additionally, refer to Figure 10 With the razor blade holder 20 connected, the first portion 112a can be completely accommodated within the plunger housing 120. In this case, the front end of the first portion 112a can be located adjacent to the front end of the plunger housing 120.

[0109] In this case, the user can identify whether the razor blade holder 20 is properly connected based on whether the first part 112a is exposed.

[0110] For example, in the disassembled state, the first portion 112a may be spaced apart from the front end of the plunger housing 120, or at least a portion of the first portion 112a may be contained within the plunger housing 120, thereby exposing at least a portion of the first portion 112a to the outside. During the connection process, the plunger 110 moves a predetermined distance along the first direction DR1, and in the normal connected state, the first portion 112a is completely contained within the plunger housing 120 and is not exposed to the outside.

[0111] Therefore, the user can identify whether the razor blade holder 20 is properly connected based on whether the first part 112a is exposed or not. Thus, the first part 112a can serve as an indicator of whether the razor blade holder 20 is connected, while the second part 112b can serve as an indicator of the degree of rotation of the razor blade holder 20.

[0112] Figure 11 It is shown Figure 8 Bottom view of the misaligned connection between the razor handle and the razor blade holder.

[0113] Reference Figure 11 and Figure 9 or Figure 10 Indicator 112 can indicate whether the connection between the razor blade holder 20 and the razor handle 10 is aligned (see...). Figure 9 or Figure 10 ) or unaligned connection state (see Figure 11 As previously mentioned, the position of indicator 112 may vary depending on whether the razor blade holder 20 and the razor handle 10 are aligned or misaligned.

[0114] In the aligned connection state, the indicator 112 is symmetrical with respect to the longitudinal central axis of the plunger housing 120 in terms of area, shape, and position. However, in the misaligned connection state, the indicator 112 is asymmetrical with respect to the longitudinal central axis of the plunger housing 120 in terms of area, shape, and position.

[0115] An indicator 112, comprising a first portion 112a formed of a straight bar shape or a shape corresponding to the front end of the plunger housing 120, can more clearly indicate the alignment and misalignment states between the razor blade holder 20 and the razor handle 10.

[0116] For example, refer to Figure 9 , Figure 10 and Figure 11 Comparison, in the aligned connection state (see Figure 9 or Figure 10 The first part 112a is longitudinally parallel to the front end of the plunger housing 120, but in a misaligned connection state (see...). Figure 11 The first part 112a is inclined longitudinally relative to the front end of the plunger housing 120.

[0117] Therefore, based on the relative alignment between the first part 112a and the front end of the plunger housing 120, the user can easily identify the aligned and misaligned connection states between the razor blade holder 20 and the razor handle 10.

[0118] Figure 12 This is a bottom view showing the shaver assembly in a separated state according to another embodiment of the present disclosure. For ease of explanation, the same reference numerals are used for parts similar to those in the foregoing embodiments, and descriptions of parts common to those in the foregoing embodiments are omitted.

[0119] Reference Figure 12 According to another embodiment of the present disclosure, the razor assembly 1 includes a razor blade holder 20 and a razor handle 10.

[0120] According to another embodiment of the razor assembly 1 of this disclosure, a first indicator 113 is provided on the outer surface of the plunger 110, and the razor blade holder 20 includes a second indicator 240. This is different from the razor handle 10 in the aforementioned embodiment.

[0121] Figure 13 This is a bottom view showing the connection state of a razor assembly according to another embodiment of the present disclosure.

[0122] Reference Figure 13When the razor blade holder 20 is connected to the razor handle 10, the second indicator 240 may overlap with the first indicator 113 by at least a portion. For example, the first indicator 113 may be formed as a through hole of a predetermined size penetrating the plunger housing 120, and the second indicator 240 may be formed in various forms such as engraving, protrusion, sticker, or stamp. The second indicator 240 may be formed with the same diameter as or smaller than that of the first indicator 113, so that the second indicator 240 overlaps with the first indicator 113 when the razor blade holder 20 and the razor handle 10 are connected. The second indicator 240 may be formed so that it can be located at the exact center of the first indicator 113 to indicate that the razor blade holder 20 and the razor handle 10 have reached an aligned connection state. When the razor blade holder 20 is connected to the razor handle 10 in an misaligned state, the second indicator 240 is not located in the center of the first indicator 113, or at least a portion of the second indicator 240 is located outside the first indicator 113.

[0123] Furthermore, the first indicator 113 and the second indicator 240 can provide the user with information regarding the installation orientation of the razor blade holder 20 and the razor handle 10. When installing the razor blade holder 20 onto the razor handle 10, the user, while confirming the positions of the first indicator 113 and the second indicator 240, adjusts the installation orientation of the razor blade holder 20 relative to the razor handle 10 to face the first indicator 113, or adjusts the installation orientation of the razor handle 10 relative to the razor blade holder 20 to face the second indicator 240. The user can adjust the installation orientation using the first indicator 113 and the second indicator 240, thereby facilitating the connection between the razor handle 10 and the razor blade holder 20.

[0124] Additionally, the first indicator 113 and the second indicator 240 can indicate the mounting and pivoting states of the razor blade holder 20. The related details are the same as in the foregoing embodiments, and therefore their detailed description is omitted.

[0125] However, compared with the aforementioned embodiments, this embodiment, which utilizes the first indicator 113 and the second indicator 240, can easily identify the aligned connection state and the misaligned connection state based on whether the first indicator 113 and the second indicator 240 overlap.

[0126] Furthermore, compared to the aforementioned embodiments, this embodiment, utilizing the first indicator 113 and the second indicator 240, allows for the identification of the pivoting state of the razor blade holder 20 based on the alignment or overlap between the first indicator 113 and the second indicator 240. For example, when the razor blade holder 20 is in a neutral state, the first indicator 113 and the second indicator 240 overlap each other. As the rotation angle of the razor blade holder 20 increases, the plunger 110 retracts along the first direction DR1, thereby allowing the identification of the pivoting state of the razor blade holder 20 based on the degree of disengagement of the second indicator 240 relative to the first indicator 113. The second indicator 240 can be configured such that when the razor blade holder 20 is at its maximum rotation angle, the second indicator 240 is completely disengaged from the first indicator 113, allowing the user to easily identify that the razor blade holder 20 has reached its maximum rotation angle.

[0127] Figure 14 This is a bottom view showing the connected state of a razor handle according to another embodiment of the present disclosure. For ease of explanation, the same reference numerals denote components similar to those in the foregoing embodiments, and repeated descriptions thereof will be omitted.

[0128] Reference Figure 14 According to another embodiment of the present disclosure, the razor handle 10 includes a first plunger 110a and a second plunger 110b, which is different from the razor handle 10 of the foregoing embodiments.

[0129] The plunger 110 may include a first plunger 110a and a second plunger 110b.

[0130] The first plunger 110a, identical to the plunger 110 in the aforementioned embodiment, provides a restoring force for elastically supporting the razor blade holder 20, thereby returning the razor blade holder 20 to a neutral position. The first plunger 110a provides a restoring force to the razor blade holder 20, which pivots about a first rotation axis AX1. The second plunger 110b provides a restoring force to the razor blade holder 20, which pivots about a second rotation axis AX2. The second rotation axis AX2 is an axis that passes through the upper and lower surfaces of the second plunger 110b, is perpendicular to the longitudinal (x-axis) and transverse (y-axis) directions, and is also perpendicular to the first rotation axis AX1. The razor blade holder 20 is capable of pivoting about the first rotation axis AX1 and pivoting left and right about the second rotation axis AX2.

[0131] The first plunger 110a may be configured to have the same structure and function as the plunger 110 in the aforementioned embodiment and another embodiment. Therefore, indicators 111, 112 and 113 as in the aforementioned embodiment and another embodiment may be provided on the outer surface of the first plunger 110a.

[0132] The second plunger 110b can be connected to and support the first plunger 110a to enable sliding. The first plunger 110a and the second plunger 110b can provide restoring force to the razor blade holder 20 in different directions around their respective rotation axes, thereby making the razor blade 230 more closely conform to the user's skin surface.

[0133] An indicator 114 may be provided on the outer surface of the second plunger 110b to indicate the state of the razor blade holder 20 pivoting left and right around the second rotation axis AX2.

[0134] The indicator 114 can be formed on the outer surface of the second plunger 110b in various forms such as engraving, protrusion, sticker, or stamp. The indicator 114 can be formed into various user-readable shapes such as lines and polygons, and its shape is not limited. In addition, the indicator 114 can be formed to have a different color than the outer surface of the second plunger 110b.

[0135] Figure 15 It is shown Figure 14 Bottom view of the second plunger in its rotating state. Figure 16 It is shown that... Figure 15 The bottom view shows the rotation state at different angles.

[0136] Reference Figure 15 The indicator 114 can be tilted, thereby tilting at a predetermined angle relative to the longitudinal direction (i.e., the x-axis direction) in proportion to the angle of pivoting of the razor blade holder 20. To make it easy to determine the degree of tilt of the indicator 114, the indicator 114 may include a straight edge parallel to the longitudinal direction (i.e., the x-axis direction).

[0137] Reference Figure 15 and Figure 16 The exposed area of ​​the indicator 114 and at least a portion of the exposed portion can vary depending on the degree of left-right pivoting of the razor blade holder 20. Thus, the user can adjust the left-right pivoting angle of the razor blade holder 20 based on the tilt, exposed area, and exposed portion of the indicator 114, thereby achieving efficient shaving.

[0138] As described above, this disclosure allows for easy verification of whether the razor handle 10 and the razor blade holder 20 are connected. According to this disclosure, it allows for easy verification of whether the razor handle 10 and the razor blade holder 20 are fully aligned and connected without misalignment. According to this disclosure, it allows for easy verification of the degree of pivoting of the razor blade holder 20 relative to its neutral position. According to this disclosure, the razor blade holder 20 can be easily mounted to the razor handle 10.

[0139] Although preferred embodiments of the present disclosure have been described with reference to the accompanying drawings, the structures described in the embodiments and the contents shown in the drawings are only the most preferred embodiments of the present disclosure and do not represent all the technical ideas of the present disclosure. Therefore, it should be understood that various equivalent solutions and modifications that can replace the foregoing embodiments may exist at the time of this application. Therefore, the above embodiments are illustrative in all respects and not restrictive.
