Description

Technical Field

[0001] This disclosure relates to razor assemblies. Background Technology

[0002] The content described in this section is merely for providing background information for this invention and does not constitute prior art.

[0003] Existing razor assemblies, often referred to as wet razors, consist of a razor blade holder and a razor handle.

[0004] The razor blade holder is configured to rotate around the razor handle between a rest position and a pivoting position away from that rest position. The pivoting motion of the razor blade holder is essentially centered on a rotation axis parallel to the arrangement direction of the razor blades.

[0005] The rotation of the razor blade holder, centered on the rotating axis, ensures smooth contact between the razor blades and the user's skin, facilitating an effective shave.

[0006] In addition, existing shaver assemblies use a rotary connector to achieve the rotational movement of the shaver blade holder. In the rotary connector method, the connector is fixed relative to the shaver handle and can rotate about a rotation axis relative to the shaver blade holder.

[0007] For example, U.S. Patent No. 9,193,077 (hereinafter referred to as "Patent Document 1") discloses a rotary connection method in such a blade holder. Specifically, the razor assembly of Patent Document 1 includes a blade holder, a connecting member rotatably fixed to the blade holder, and a handle connected to the connecting member, wherein the connecting member is configured to be fixed in position relative to the handle.

[0008] The rotary connection allows the rotating shaft to be positioned close to the foremost razor blade, thereby improving the rotation function.

[0009] However, the rotary connection method results in a larger size for the razor blade holder because it forms a unit (hereinafter referred to as the "blade holder unit") with the connector that is rotatably connected to the razor blade holder.

[0010] The blade holder unit is sold or supplied separately from the razor handle, housed within a box such as a dispenser. In this case, if the size of the blade holder unit increases, the likelihood of damage to the blade holder unit increases.

[0011] Another existing shaver assembly uses a fixed connector to achieve the rotational movement of the shaver blade holder. In this fixed connector configuration, the connector is fixed relative to the shaver blade holder but can rotate about a rotation axis relative to the shaver handle. For example, this fixed connector configuration is disclosed in Patent Publication No. 100903191 (hereinafter referred to as "Patent Document 2").

[0012] For the fixed connector method, the connector is fixed to the razor blade holder, which has the advantage of a relatively smaller blade holder unit size compared to the rotary connector method.

[0013] However, the fixed connector is rotatably placed inside the razor handle, which complicates the structure of the razor handle and reduces its durability.

[0014] Specifically, in the fixed connector configuration, the shaver assembly includes a holder for connection to the connector. The holder is located on one side of the shaver handle and is rotatably connected to the shaver handle about a rotation axis. This rotating structure of the holder can contribute to a decrease in the durability of the shaver assembly.

[0036] The following is a detailed description of some embodiments of the present disclosure with reference to the accompanying drawings. When assigning reference numerals to the components in the drawings, the same reference numerals are used as much as possible for the same components, even when labeled in another drawing. Furthermore, in the process of describing the present disclosure, detailed descriptions of related well-known structures or functions will be omitted if it is believed that such detailed descriptions would obscure the main points of the disclosure.

[0037] In describing the components involved in the embodiments of this disclosure, symbols such as first, second, i), ii), a), and b) may be used. These symbols are merely used to distinguish the component from other components and do not limit the nature, sequence, or order of the corresponding components. When the specification states that a part "comprises" or "has" a certain component, unless there is an explicit statement to the contrary, it indicates that other components are further included, but not excluded.

[0038] Figure 1 This is a perspective view of a razor assembly (10) according to an embodiment of the present disclosure.

[0039] Figure 2 This is a rear perspective view of a razor assembly (10) according to an embodiment of the present disclosure.

[0040] Reference Figure 1 and Figure 2 The razor assembly (10) may include a razor cartridge (12), a connector (130), and a holder (140). The razor cartridge (12) may include at least one shaving blade (110) and a blade housing (120).

[0041] At least one razor blade (110) may have a cutting edge (112) for cutting body hair.

[0042] The blade housing (120) can accommodate at least one longitudinally positioned razor blade (110). Here, longitudinal refers to the width direction of the blade housing (120). For example, Figure 1 In the diagram, the vertical direction is parallel to the X-axis.

[0043] At least one razor blade (110) is held in a position on one side of the blade housing (120) by a plurality of clips (125).

[0044] The blade housing (120) may include a top side (121), a bottom side (123), a guard (122), and a cap (124).

[0045] The top (121) can be the surface of the blade housing (120) facing the cutting edge (112), and the bottom (123) can be the surface of the blade housing (120) facing the top (121).

[0046] On the top (121) of the blade housing (120), a protective part (122) may be located in front of the razor blade (110), and a cover part (124) may be located behind the razor blade (110). The front and rear of the razor blade (110) are defined based on the shaving direction of the razor blade holder (12).

[0047] When shaving, the protective part (122) can stretch the skin in the shaving direction before the razor blade (110) cuts the body hair.

[0048] This allows the user's body hair to stand up perpendicular to the user's skin, making it easier for the razor blade (110) to cut the body hair.

[0049] The connector (130) can be fixed to one side of the blade housing (120). For example, to reinforce the connection between the connector (130) and the shaver handle (not shown), the connector (130) can be manufactured as a separate component from the blade housing (120) and then installed and fixed to the blade housing (120). In this case, the connector (130) can be fixed to the bottom (123) of the blade housing (120), or to one side between the top (121) and the bottom (123).

[0050] However, this disclosure is not limited thereto; the connector (130) may also be integrally formed with the blade housing (120). For example, the connector (130) may also be injection molded on the underside (123) or one side of the blade housing (120). In this case, the connector (130) and the blade housing (120) may be integrally formed.

[0051] The holder (140) is rotatably connected to the connector (130) with a rotational axis (RA) parallel to the longitudinal direction as its center. The position of the holder (140) can be fixed relative to the razor handle (not shown).

[0052] The technical feature of a razor assembly (10) according to an embodiment of the present disclosure is that the position of the connector (130) is fixed relative to the razor blade holder (12), the position of the holder (140) is fixed relative to the razor handle (not shown), and the connector (130) is movable relative to the holder (140), thereby realizing the pivot function of the razor blade holder (12).

[0053] Thus, the razor assembly (10) according to an embodiment of the present disclosure has the effect of reducing the size of the cartridge unit consisting of the razor blade holder (12) and the connector (130) while improving the durability of the razor assembly (10).

[0054] Alternatively, the grip (140) can be a component independent of the razor handle (not shown) or it can be integrally formed with the razor handle.

[0055] The razor assembly (10) may further include a recovering force providing unit (150) and an ejecting unit (160).

[0056] The restoring force providing part (150) can provide a restoring force for restoring the connector (130) that is rotating around the pivot (RA) to the rest position, and the disengagement part (160) can separate the connector (130) from the holder (140).

[0057] Figure 3 The diagram shows... Figure 2 The razor blade holder (12) is detached from the handle (140).

[0058] Reference Figure 3 The connector (130) may include a connector body (132) and a first connecting portion (134), and the holder (140) may include a holder body (142) and a second connecting portion (144).

[0059] The connector body (132) can form the shape of the connector (130) and define the receiving space (S) for accommodating the holder (140).

[0060] The first engagement portion (134) may be formed on one side of the connector body (132). Specifically, the first engagement portion (134) may be formed facing at least a portion of the holder (140) housed in the receiving space (S), such as at least a portion of the second engagement portion (144).

[0061] The first joint (134) may include a cantilever (1342) and a first surface (1344).

[0062] The cantilever beam (1342) may be offset toward the center of the connector (130). Specifically, the cantilever beam (1342) may be offset toward the central axis (CA) that is perpendicular to the longitudinal direction and passes through the center of the connector (130).

[0063] Furthermore, the cantilever beam (1342) may extend forward in the mounting direction from one side of the connector (130), such as one side of the connector body (132).

[0064] The first face (1344) may be formed on one side of the first joint (134), for example, at the free end of the cantilever beam (1342).

[0065] The "forward" mounting direction refers to the direction of movement of the gripper (140) when it is installed in the receiving space (S) of the connector (130). Furthermore, the "rear" mounting direction, described later, refers to the direction of movement of the gripper (140) when it is disengaged from the receiving space (S) of the connector (130). For example, Figure 3 In the diagram, the direction in front of the mounting direction is the positive direction of the Z-axis, and the direction behind the mounting direction is the negative direction of the Z-axis.

[0066] The second connecting part (144) may be oriented toward one side of the gripper body (142). Specifically, the second connecting part (144) may extend forward in the mounting direction from one side of the gripper body (142).

[0067] The second joint (144) can be accommodated in the accommodating space (S) of the connector (130), and when accommodated in the accommodating space (S), it can face at least a portion of the first joint (134).

[0068] The second coupling (144) may include a protrusion (1442) for hook coupling with one end of the cantilever beam (1342).

[0069] The protrusion (1442) can be formed parallel to the longitudinal direction and protruding from one end of the second joint (144) away from the grip body (142).

[0070] The connector (130) and the gripper (140) can be connected by engaging the first engagement portion (134) and the second engagement portion (144). For example, the second engagement portion (144) can be engaged with the first engagement portion (134). In this case, the protrusion (1442) of the second engagement portion (144) can be engaged with one end of the cantilever beam (1342) of the first engagement portion (134).

[0071] However, this disclosure is not limited thereto. The second joint (144) can also be connected to the first joint (134) by means of snap-fit ​​or other means.

[0072] The connector (130) may have at least one first engagement portion (134), preferably, it may have a pair of first engagement portions (134). In this case, the pair of first engagement portions (134) may be arranged facing each other and have a symmetrical shape.

[0073] The second coupling portion (144) may be arranged at a position corresponding to the first coupling portion (134). For example, when the connector (130) has a pair of first coupling portions (134), the holder (140) may also have a pair of second coupling portions (144). In this case, each second coupling portion (144) may be arranged at a position corresponding to each first coupling portion (134).

[0074] The protrusion (1442) may include a second surface (1444) and a third surface (1446).

[0075] The second surface (1444) may be formed on the side of the protrusion (1442) near the gripper body (142). Furthermore, the second surface (1444) may face the first surface (1344) of the first coupling portion (134) when the gripper (140) is mounted on the connector (130).

[0076] When the connector (130) rotates relative to the holder (140) about the rotation axis (RA), the first surface (1344) can move relative to the second surface (1444) along with the second surface (1444).

[0077] The first surface (1344) may have a concave surface, and the second surface (1444) may have a concave surface corresponding to the concave surface of the first surface (1344).

[0078] Thus, the second surface (1444) can be securely mounted on the first surface (1344), and the connector (130) can rotate more smoothly relative to the gripper (140). A detailed description of this will follow. Figure 7 The relevant sections will describe this.

[0079] Refer again Figure 3 The third surface (1446) may be formed on the other side of the protrusion (1442) that is separated from the gripper body (142). The third surface (1446) may be configured to apply pressure to the cantilever beam (1342) during the connection of the gripper (140) and the connector (130).

[0080] When the cantilever beam (1342) is compressed by the third surface (1446), the cantilever beam (1342) can elastically deform in a direction away from the center of the connector (130). A detailed description of this will follow. Figure 6 The relevant sections will describe this.

[0081] Figure 4 This is an exploded perspective view of a razor assembly (10) according to an embodiment of the present disclosure.

[0082] Reference Figure 4 The restoring force providing part (150) may include a piston (plunger, 152) and an elastic member (elasticmember, 154). The piston (152) may include a piston body (plunger body, 1522) and a cam surface (cam surface, 1524).

[0083] At least a portion of the piston body (1522) can penetrate through the through hole (146) of the gripper body (142). The piston body (1522) is capable of moving parallel to the mounting direction with the through hole (146) in its position.

[0084] A through hole (146) may be formed between a pair of second joints (144). Therefore, at least a portion of a restoring force providing part (150), such as a piston body (1522), may be arranged between a pair of second joints (144). Thus, the restoring force providing part (150) can be arranged to make efficient use of space and has the effect of providing restoring force with a simpler structure.

[0085] A cam surface (1524) may be formed on one end of the piston body (1522) near the blade housing (120). The cam surface (1524) may engage with a portion of the blade housing (120) or a portion of the connector (130) to provide a restoring force to the razor blade holder (12).

[0086] The elastic member (154) can be configured to provide a spring force to the piston (152). The spring force generated by the elastic member (154) can act as a restoring force to return the razor blade holder (12) to the neutral position.

[0087] The side of the elastic member (154) near the blade housing (120) can be connected to the piston (152), for example, the piston body (1522).

[0088] Furthermore, the other side of the elastic member (154) away from the blade housing (120) may be connected to the disengagement portion (160), such as the disengagement portion body (162). However, this disclosure is not limited to this, and the other side of the elastic member (154) may also be connected to a portion of a component other than the disengagement portion (160), such as a part of the razor handle (not shown).

[0089] The piston (152) may further include a stopper (1526).

[0090] The limiter (1526) can protrude from one side of the piston body (1522) in a direction perpendicular to the extension direction of the piston body (1522).

[0091] In addition, the limiter (1526) can be arranged behind the holder body (142) in the mounting direction, facing the side of the holder body (142) away from the blade housing (120).

[0092] When the piston body (1522) moves forward in the mounting direction, the limiter (1526) can contact one side of the holder body (142). This prevents the piston body (1522) from moving forward in the mounting direction.

[0093] The ejection unit (160) may include an ejection unit body (12) and an arm (164).

[0094] The detachment body (162) can be arranged behind the holder (140) in the mounting direction.

[0095] The arm (164) can extend forward from one side of the detachment body (162) toward the mounting direction.

[0096] At least a portion of the gripper (140) may be arranged between two arms (164). For example, a portion of the second coupling (144) and the gripper body (142) may be arranged between two arms (164). Thus, the disengagement portion (160) can be arranged to effectively utilize space.

[0097] The arm (164) can be arranged behind the protrusion (1442) in the mounting direction and move relative to the protrusion (1442) in the mounting direction.

[0098] As the arm (164) moves forward along the protrusion (1442) in the mounting direction, the arm (164) applies pressure to the cantilever beam (1342) of the first coupling (134) in a direction away from the center of the connector (130). This releases the coupling between the first coupling (134) and the second coupling (144), allowing the connector (130) to detach from the holder (140). A detailed description of this will follow. Figure 9 The relevant sections will describe this.

[0099] Refer again Figure 4 The connector (130) may further include a third coupling portion (136). Furthermore, the blade housing (120) may further include a fourth coupling portion (126).

[0100] One of the third coupling portion (136) and the fourth coupling portion (126) may include a coupling protrusion, and the other of the third coupling portion (136) and the fourth coupling portion (126) may include a coupling groove corresponding to the protrusion. In this case, the coupling protrusion can be inserted into the coupling groove to connect the connector (130) and the blade housing (120).

[0101] However, this disclosure is not limited thereto. For example, the third coupling (136) and the fourth coupling (126) can also be connected by hook coupling or snap-fit.

[0102] Figure 5 This is a rear view of a razor assembly (10) according to an embodiment of the present disclosure.

[0103] The technical feature of a razor assembly (10) according to an embodiment of the present disclosure is that the connection between the connector (130) and the holder (140) and the rotation function of the razor blade holder (12) are realized simultaneously by using the first connecting part (134) and the second connecting part (144).

[0104] Therefore, in a razor assembly (10) according to an embodiment of the present disclosure, the connection between the connector (130) and the holder (140) and the rotation axis (RA) of the razor blade holder (12) can be realized in a position close to each other.

[0105] Additionally, the rotation axis (RA) of the razor blade holder (12) is generally located in front of the foremost blade (110A) among the razor blades (110). Therefore, the connection between the connector (130) and the holder (140) can also be achieved in front of the foremost blade (110A), and the connector (130) can be located in the area relatively biased towards the front of the blade housing (120).

[0106] For example, refer to Figure 5 When viewed from the underside (123) of the blade housing (120), the connector (130) does not overlap with at least one shaving blade (110). In this case, the rising space (R) is wider, and the rinsing of the shaving blade (110) based on the rinsing water is more effective.

[0107] However, this disclosure is not limited thereto. For example, the connector (130) may also be arranged on the blade housing (120) such that at least a portion of the connector (130) overlaps with at least one razor blade (110).

[0108] In this case, the connection between the connector (130) and the blade housing (120) can be achieved over a wider area, so that the connector (130) can be more securely fixed to the blade housing (120).

[0109] Figure 6 The illustration shows the process of assembling a razor blade holder (12) to a second joint (144) according to an embodiment of the present disclosure.

[0110] Figure 6 For ease of explanation, a portion of the upper region of the connector body (132) has been omitted.

[0111] Reference Figure 6 (a) and Figure 6 (b) During the period when the second joint (144) of the holder (140) is inserted into the receiving space (S) of the connector (130), a cam action can be generated between the third surface (1446) of the protrusion (1442) and the cantilever beam (1342) of the first joint (134).

[0112] The third face (1446) applies pressure to the cantilever beam (1342) in a direction away from the center of the connector (130) through this cam action. The cantilever beam (1342) under pressure from the third face (1446) can elastically deform in a direction away from the center of the connector (130).

[0113] In addition, in order to smoothly achieve the cam action, before the holder (140) is engaged with the connector (130), the maximum longitudinal spacing of the pair of second engagement portions (144) can be set to be greater than the minimum longitudinal spacing of the first engagement portion (134).

[0114] For example, in the state before the holder (140) is attached to the connector (130), the longitudinal spacing between the free ends of a pair of protrusions (1442) can be set to be greater than the longitudinal spacing between the free ends of a pair of cantilever beams (1342).

[0115] Reference Figure 6 (b) and Figure 6 (c) When the second joint (144) is fully inserted into the receiving space (S), the cam action state between the third surface (1446) and the cantilever beam (1342) can be released.

[0116] By releasing the cam action, the third surface (1446) no longer applies pressure to the cantilever beam (1342), and thus, the cantilever beam (1342) is re-biased toward the center of the connector (130) by elastic force.

[0117] When the cantilever beam (1342) is re-biased toward the center of the connector (130), the first surface (1344) of the first joint (134) and the second surface (1444) of the second joint (144) can face each other, thereby allowing the first joint (134) and the second joint (144) to engage with each other.

[0118] In this case, the second surface (1444) may have a shape corresponding to the shape of the first surface (1344), so that the first joint (134) and the second joint (144) can be joined more firmly.

[0119] Furthermore, the razor assembly (10) according to an embodiment of this disclosure facilitates the connection between the first connection (134) and the second connection (144) by simply inserting the second connecting portion (144) of the handle (140) into the receiving space (S) of the connector (130). Thus, the user can easily mount the razor blade holder (12) onto the razor handle (not shown).

[0120] Figure 7 The illustration shows the rotational state of a razor blade holder (12) according to an embodiment of the present disclosure. Specifically, Figure 7 It is along Figure 6 A cross-sectional view of the razor assembly (10) cut along the A-A' direction.

[0121] also, Figure 7 (a) The illustration shows the razor blade holder (12) in a neutral position. Figure 7 (b) The diagram shows the state in which the razor blade holder (12) rotates from the neutral position.

[0122] Reference Figure 7 (a) and Figure 7 (b) The first surface (1344) may have a concave surface, and the second surface (1444) may have a concave surface corresponding to the concave surface of the first surface (1344). By smoothly rotating the razor blade holder (12), the surfaces of the first surface (1344) and the second surface (1444) may have an arc profile centered on the axis of rotation (RA).

[0123] Furthermore, the second face (1444) can be closer to the axis of rotation (RA) than the first face (1344).

[0124] Furthermore, the rotating shaft (RA) may extend through at least a portion of the second joint (144), such as the front region of the second joint (144). Thus, the rotating shaft (RA) can be closer to the foremost blade (110A) of the razor blade (110), which can further improve the rotation function of the razor assembly (10).

[0125] However, this disclosure is not limited thereto. The rotating shaft (RA) may pass through the center of the second joint (144) or the rear region of the second joint (144), or may not pass through the second joint (144).

[0126] When the rotating shaft (RA) passes through the second joint (144), the rotating shaft (RA) is located near the second joint (144) and can penetrate the area of ​​the blade housing (120) near the second joint (144).

[0127] During the rotation of the connector (130) relative to the holder (140) about the rotation axis (RA), the first surface (1344) can move relative to the second surface (1444) along with the second surface (1444).

[0128] During the rotation of the connector (130), in order to maintain the contact area between the first surface (1344) and the second surface (1444) at a certain size, the first surface (1344) can have a larger area than the second surface (1444). Thus, regardless of the degree of rotation of the connector (130), the first mating portion (134) and the second mating portion (144) can maintain a firm mating state.

[0129] At least one of the blade housing (120) and the connector (130) may define a first stop surface (P1) and a second stop surface (P2) for limiting the rotational range of the connector (130). A second engagement portion (144), such as a protrusion (1442), may be supported by either the first stop surface (P1) or the second stop surface (P2), thereby limiting the rotational range of the connector (130).

[0130] For example, refer to Figure 7 (a) The protrusion (1442) is supported by the first stop surface (P1), thereby restricting the connector (130) from moving. Figure 7 Rotation in a counter-clockwise direction based on the reference. Additionally, refer to... Figure 7 (b) The protrusion (1442) is supported by the second stop surface (P2), thereby restricting the connector (130) from moving. Figure 7 Rotation in a clockwise direction based on the reference point.

[0131] Additionally, the connector (130) is fixed to the razor blade holder (12), and the grip (140) is fixed to the razor handle (not shown). When the connector (130) rotates relative to the grip (140), the razor blade holder (12) can rotate relative to the razor handle (not shown).

[0132] Figure 8 The illustration shows the operation of the restoring force providing part when the razor blade holder (12) rotates according to an embodiment of the present disclosure. Specifically, Figure 8 It is along Figure 6 A cross-sectional view of the razor assembly (10) cut along the B-B' direction.

[0133] also, Figure 8 (a) The illustration shows the razor blade holder (12) in a neutral position. Figure 8 (b) The illustration shows the razor blade holder (12) in a state of rotation from the neutral position.

[0134] Reference Figure 8 (a) and Figure 8 (b) When the razor blade holder (12) starts to rotate from the neutral position, the cam surface (1524) can produce a cam action with a part of the blade housing (120) or a part of the connector (130).

[0135] Through this cam action, the piston (152) can apply pressure rearward in the mounting direction, or provide a restoring force to the razor blade holder (12). The process by which the restoring force providing part (150) provides a restoring force to the razor blade holder (12) is explained in detail below.

[0136] The side of the elastic member (154) near the blade housing (120) can be connected to the piston body (1522), and the other side of the elastic member (154) away from the blade housing (120) can be connected to the disengagement body (162) or a part of the razor handle (not shown).

[0137] Furthermore, the position of the other side of the elastic member (154) can be fixed. Therefore, based on the action of the cam, when the piston (152) moves rearward in the mounting direction, the elastic member (154) can be compressed.

[0138] When the elastic component (154) is compressed, an elastic force can be generated inside the elastic component (154), and the elastic force of the elastic component (154) can be transmitted to the razor blade holder (12) through the cam surface (1524) of the piston (152).

[0139] The elastic force transmitted to the razor blade holder (12) can restore the rotating razor blade holder (12) to the neutral position. That is, the elastic force generated by the elastic member (154) can act as a restoring force to restore the razor blade holder (12).

[0140] Figure 9 The illustration shows the process of detaching the razor blade holder (12) from the second joint (144) according to an embodiment of the present disclosure.

[0141] Reference Figure 9 (a) and Figure 9 (b) With the connector (130) connected to the grip (140), the user can move the arm (164) forward toward the protrusion (1442) in the mounting direction. For example, the user can move the arm (164) forward in the mounting direction by pushing the button (not shown) connected to the disengagement part (160) forward in the mounting direction.

[0142] At this time, the position of the piston (152) is fixed, and thus the position of one side of the elastic member (154) connected to the piston (152) can also be fixed. Therefore, when the other side of the elastic member (154) moves forward in the mounting direction together with the disengagement body (162), the elastic member (154) arranged between the piston (152) and the disengagement body (162) can be compressed.

[0143] Additionally, the arm (164) can be located behind the protrusion (1442) in the mounting direction. Therefore, as the arm (164) moves forward in the mounting direction, the cantilever beam (1342) can be elastically deformed in a direction away from the center of the connector (130).

[0144] In this case, the cantilever beam (1342) undergoes elastic deformation in a direction away from the center of the connector (130), thereby releasing the connection between the first joint (134) and the second joint (144).

[0145] Reference Figure 9 (b) After the connection between the first joint (134) and the second joint (144) is released, the cantilever beam (1342) can be subjected to pressure applied by the arm (164). At this time, the cantilever beam (1342) can be fully extended in a direction away from the center of the connector (130).

[0146] The space between the two cantilever beams (1342) is sufficient to allow the two second joints (144) to detach from the connector (130). Therefore, the user can separate the razor blade holder (12) from the second joints (144) with the cantilever beams (1342) fully extended based on the arms (164).

[0147] Reference Figure 9 (c) When the razor blade holder (12) is separated from the second joint (144), the elastically deformable cantilever beam (1342) can be re-biased toward the center of the connector (130) based on the elastic force.

[0148] Additionally, the detachment body (162) can be connected to the other side of the elastic member (154). Therefore, when the razor blade holder (12) is separated from the second coupling (144), the detachment part (160) can be restored rearward in the mounting direction based on the elastic member (154).

[0149] In a shaver assembly (10) according to an embodiment of the present disclosure, the generation of restoring force of the restoring force providing part (150) and the restoration of the initial position of the disengagement part (160) can be achieved by an elastic member (154) as a single component. That is, the restoring force providing part (150) and the disengagement part (160) can share the elastic member (154), thereby simplifying the structure of the restoring force providing part (150) and the disengagement part (160).

[0150] The above description is merely illustrative of the technical concept of this embodiment. For those skilled in the art, various modifications and variations can be made without departing from the essential characteristics of this embodiment. Therefore, this embodiment is not intended to limit the technical concept but is for illustrative purposes, and the scope of the technical concept is not limited by the described embodiment. The scope of protection of this embodiment should be interpreted based on the appended claims, and all technical concepts within the equivalent scope should be interpreted as falling within the scope of the rights of this embodiment.
