Description

Technical Field

[0001] This disclosure relates to an accessory component for a grooming device and the grooming device itself. In some embodiments, this disclosure relates to a handle extension for a hair-cutting device and to a hair-cutting setup. In some embodiments, this disclosure relates to an accessory formed as a so-called back handle extension, which can be attached to the grooming device to increase the device's range of operation on a user's body. In some embodiments, this disclosure relates to attachments and accessories configured to be attached to grooming devices that are also independently operable, i.e., without the attachments / accessories. Background Technology

[0002] Grooming devices are generally known and commonly used in the personal care field, including hair care and skin care. Grooming devices include hair trimmers, such as clippers, scissors, and razors. Electric grooming devices exist, such as motor-powered hair trimmers. Grooming devices can also include epilators, electric tweezers, etc. Grooming devices can also include massagers and similar devices. Generally, grooming devices are used in the personal care field to give individuals a better appearance.

[0003] Hair trimming equipment is an important type of grooming device. There are powered and non-powered hair trimming devices. Hair trimming devices can include trimmers, scissors, and razors.

[0004] Motor-driven hair cutting devices typically include two cutting elements that can move relative to each other to cut hair between them. Trimmers / combedgers with at least a pair of comb-like blades having cutting edges that slide rapidly back and forth relative to each other to cut hair positioned between the teeth of the blades in a scissor-like action are also present. Embodiments, which may be referred to as metal-blade razors, also exist, including a perforated metal screen facing the skin and a moving cutter located behind the screen to cut hair. Combined hair cutting devices with metal-blade shaving and trimming sections are also possible. Furthermore, hair cutting devices also include non-powered razors (also known as safety razors) with one or more non-powered cutting blades, where the cutting action involves cutting hair downwards while moving the device along the skin. Shaving with a safety razor is typically performed as a wet shave. Shaving with a powered hair cutting device can include both wet and dry shaving.

[0005] An important aspect of grooming devices is their maneuverability, operability, and visibility when operated and / or applied to areas of the user's body. This can include applications to easily accessible and observable body areas, such as the face (when used in front of a mirror), arms, etc. There is also often a preferred operating orientation for the device to achieve optimal application results.

[0006] However, grooming operations need to be performed on hard-to-reach parts of the body, including the user's back. For this purpose, it is known that the handle extension can be banana-shaped or similar in shape to allow the user to reach their own back (and other hard-to-reach areas) using the manipulating head of the grooming device.

[0007] US2011 / 0225826A1 discloses an integrated shaver and hair trimmer device comprising a shaver / trimmer assembly and a handle assembly, wherein the shaver / trimmer assembly has a specific interface for attaching the handle assembly, and wherein the interface is formed at a mounting end of the housing of the shaver / trimmer assembly, the mounting end being opposite to the hair cutting unit. The handle assembly integrates a pivoting mechanism. The handle assembly does not occupy the original handle portion of the shaver / trimmer assembly, but is coupled to the shaver / trimmer assembly only at the mounting end.

[0008] US2009 / 0163932A1 discloses a hair removal device comprising a housing with an integrated sliding mechanism. The body portion of the housing is slidably disposed within a retainer portion, and the body portion is retractable relative to the retainer portion, thus making the hair removal device generally length-adjustable. Additionally, a pivoting mechanism may be disposed between the body portion and the retainer portion. The permanent inclusion of length adjustment and a pivoting mechanism makes the hair removal device larger and heavier, which diminishes the operability of the device in standard cases where an extension / expansion configuration is not required (e.g., in facial hair removal).

[0009] US2020 / 0230836A1 discloses a non-powered adjustable razor having a handle whose length is adjustable by inserting or removing one or more telescopic elements.

[0010] For example, other accessory components for grooming devices are disclosed in US2021 / 0308886A1, WO2007 / 069177A2, WO2017 / 021202A1, and WO2024 / 068393A1. US2021 / 0308886A1 discloses a clipper blade protector arranged as a cap attachable to the cutting head of a grooming clipper. US2021 / 0308886A1 discloses a charging holder for a hair cutting instrument. WO 2017 / 021202A1 discloses a hair container that can be attached to a hair cutting instrument together with an attachment comb. WO 2024 / 068393A1 discloses a cleaning device for a personal care appliance, such as a shaving device, which can be inserted into the cleaning device to clean its operating head there.

[0011] Due to a lack of visibility and accessibility, cutting hair and performing other grooming operations on one's own back and other hard-to-reach body areas can sometimes be challenging. As a result, controllability is also compromised, also considering the leverage effect created by the extended handle. Furthermore, when dealing with hard-to-reach body parts, hair cutting devices often cannot achieve optimal orientation relative to the skin (e.g., relative to the orientation to be used for cutting hair on the face).

[0012] Therefore, this hair-cutting process is usually accompanied by some discomfort, which may include skin irritation (redness) and abrasions. Furthermore, the combing results may be unsatisfactory, for example, when some sections are missed due to a lack of visibility, accessibility, and control. Sometimes, users tend to increase the contact pressure on the hair-cutting area, which further increases the risk of skin irritation or even injury.

[0013] In addition to the handle extension, other accessory components may be included, such as a stand for the combing device, a cleaning box (e.g., an ultrasonic cleaning device), a charging unit, and a combined stand with charging capabilities. Generally, an easy-to-operate and reliable coupling between the accessory components and the corresponding combing device is sought. Repeated coupling and decoupling of the accessory components and the combing device should not negatively impact the performance and / or appearance of the device. Furthermore, even in cases of repeated coupling and decoupling, a certain level of accuracy must be ensured. Moreover, operational errors should not lead to unnecessary loosening of the connection between the combing device and / or accessories. Summary of the Invention

[0014] In view of the foregoing, the object of this disclosure is to provide an accessory component for a combing device and a combing apparatus including the combing device and the accessory component, which enables reliable and stable on-demand coupling and decoupling between the combing device and the accessory component. Preferably, an easy-to-operate interface is provided between the combing device and the accessory component. Preferably, the interface between the combing device and the accessory component provides separation protection features. Preferably, the interface does not require substantial design changes at the combing device. More preferably, the design of the accessory simplifies manufacturing, thereby reducing production and assembly costs. It is also desirable to provide specific embodiments of the accessory component, particularly a handle extension that extends the operating range of the combing device. In this case, it is preferred that the handle extension does not impair the original function and operability of the combing device when not attached.

[0015] In a first aspect of this disclosure, an accessory component for a combing device is provided, the accessory component comprising:

[0016] The attachment is configured to be coupled to the combing device, and

[0017] A locking unit is formed in the attachment portion and includes at least one rocking lever having an engagement portion and a release portion.

[0018] A detent nose is formed in the joint.

[0019] The at least one rocker arm is pivotable about a hinge axis between an engaged position and a released position, and

[0020] The at least one rocker arm can be moved to the release position by overcoming the biasing force that pushes the at least one rocker arm to the engagement position.

[0021] The aforementioned aspect is based on the understanding that, since the rocker arm has a certain tendency to assume an engaged position, a locking unit with at least one rocker arm can achieve reliable and repeatable coupling between the accessory component and the combing device, while the rocker arm can be externally actuated into a released position. The rocker arm can only disengage from the combing device after the bias force has been overcome.

[0022] In some embodiments, a biasing force is inherently generated when the combing device and accessory components are in the installed state. This may involve the auxiliary component moving a rocker arm, thereby generating the biasing force.

[0023] A joystick can be operated to engage and / or disengage the combing equipment. This allows for both positive-fit and force-fit connections between the combing equipment and accessory components.

[0024] In some embodiments, the combing device is provided with one or more openings, gaps, grooves, and / or recesses that can be engaged by a brake nose of a rocker arm. Therefore, only small design features need to be formed at the combing device.

[0025] The hinge axis does not necessarily include different pins and corresponding bearings. Instead, the hinge axis can also include an integral hinge / living hinge. This can include embodiments in which the position of the hinge axis is not permanently fixed, but can move slightly with the actuation of the rocker arm (instantaneous hinge axis).

[0026] In some embodiments, the brake nose is an inwardly projecting snap-fit ​​nose. In some embodiments, when two or more levers are provided, the brake nose projects inward, i.e., toward the combing device. The brake nose may be referred to as a locking nose.

[0027] The use of a rocker arm with engagement and release mechanisms ensures a secure and stable attachment to the combing equipment, preventing accidental disengagement during use. The rocker arm itself provides a locking element (brake nose) and an actuation part for disengagement (release part). Therefore, the number of parts required for the locking feature and its actuation can be significantly reduced.

[0028] In an exemplary embodiment, the engagement and release portions are formed on opposite sides of the hinge axis. In some embodiments, the rocker arm has a seesaw-like design. Having engagement and release portions on opposite sides of the hinge axis facilitates actuation of the locking unit, particularly for disengagement. The release portion can be pressed or pushed, allowing the rocker arm to enter the released position. Disengagement can be achieved by pressing / pushing rather than pulling.

[0029] In another exemplary embodiment, at least one rocker arm can be moved to a released position by actuating the release mechanism. Therefore, it is not necessary to act directly on the engagement (e.g., by pulling the engagement). The design of the rocker arm and hinge axis allows for a favorable lever action that facilitates separation. Thus, the locking unit can be an easy-to-use mechanism for releasing the attachment, allowing for quick and simple operation.

[0030] In summary, the rocker arm can have three different states / positions. For example, there is a neutral position in which the brake nose is positioned in its most inward position. The rocker arm is in the neutral position when no external force is applied. Coupling between the accessory component and the combing device can include forced displacement of the rocker arm due to the shape of the combing device, thereby generating a biasing force that pushes the brake nose into the engagement groove at the combing device. In this way, the rocker arm can enter the engagement position. To disengage, the rocker arm can enter the release position by overcoming the biasing force, allowing the brake nose to disengage from the engagement groove.

[0031] In some embodiments, the locking unit has a self-locking feature, wherein the pull-out force applied to the combing device results in a torque or force that further engages the brake nose with the engagement recess. This can be achieved through proper design, arrangement, and orientation of the brake nose and hinge shaft relative to the direction of the pull-out force.

[0032] Therefore, when the release mechanism of the rocker arm is not actuated, the pulling force can actually increase the holding force between the combing device and the accessory components. In short, the accessory components and the combing device can be securely held in place during use.

[0033] For example, the self-locking feature can be achieved by positioning the hinge axis closer to the longitudinal direction parallel to the center of the pull-out force than the brake nose. This is particularly useful when the brake nose is positioned further forward than the hinge axis when viewed in the direction of the pull-out force. Other embodiments of this self-locking feature share the common feature that at least one rocker arm is pushed into the engaged position when the pull-out force is applied to the brake nose.

[0034] More generally, a locking unit having at least one rocker arm can be configured such that the normal (vector) on the brake nose of the rocker arm passes through the hinge axis on the outer side, spaced, for example, from the wall of the container provided by the attachment. Essentially, the normal force caused by the pull-out force coincides with the normal. This design ensures that when the normal force caused by the pull-out force and substantially parallel to the normal of the contact surface acts on the brake nose, particularly on the contact surface of the brake nose, at least one rocker arm is pushed into the engaged position. In other words, the normal on the contact surface facing the hinge axis must pass through the hinge axis in a way that deviates from the outer side. This is particularly applicable to the portion of the contact surface facing the hinge axis that, when in the engaged position, actually contacts the engagement recess to secure the attachment there.

[0035] In another exemplary embodiment, the locking unit includes a movable hinge forming a hinge axis. The movable hinge is integrally formed with adjacent elements of the rocker arm and accessory components. The movable hinge can provide a sufficiently defined hinge axis. Furthermore, when the rocker arm is moved to the engaged position, the movable hinge can serve as an energy reservoir for the biasing force.

[0036] Forming the hinge axis as a movable hinge eliminates the need for additional parts and assembly work. Therefore, the manufacturing and assembly of accessories can be simplified.

[0037] In another exemplary embodiment, the attachment and the locking unit are integrally formed. That is, the basic components of the accessory part defining the interface for coupling with the combing device can be integrally formed. This includes several embodiments in which the attachment, the locking unit, and the hinge shaft are integrally formed. As used herein, the term integrally formed refers to a single-piece design.

[0038] The integral formation of related parts of the accessory components increases their structural integrity and durability. Since there are no separate assembly steps required for single-piece designs, overall production costs can be reduced.

[0039] In some embodiments, the attachment and the locking unit with a hinge axis are integrally formed injection-molded plastic parts. For example, the attachment can be provided as a container configured to accommodate a combing device. The locking unit can be formed in the wall of the container.

[0040] By integrating rocker arms, hinge axes, and other structural components into a single molded part, the production and assembly process can be simplified. Furthermore, the stability and reliability of the functional components in accessory parts can be enhanced.

[0041] In another exemplary embodiment, the attachment portion forms a container suitable for the original handle portion of the combing device. The container may be an injection-molded plastic part. The attachment portion may integrate other elements.

[0042] The container can be tubular and / or quiver-shaped, providing a base for the combing equipment, which can be inserted into the container for coupling the combing equipment and accessories. The (internal) geometry of the container can be adapted to the geometry of the original handle portion of the combing equipment. The original handle portion is the part typically used for gripping and manipulating the combing equipment when accessory parts are not attached to it.

[0043] In another exemplary embodiment, the at least one rocker arm is arranged as a pivotable rod with inner and outer sides, wherein one or more reinforcing ribs are formed on the inner side. Thus, the rocker arm can be relatively flat, taking into account the wall thickness limitations of injection-molded parts, but can also be quite rigid. In summary, due to the increased stiffness, the creep of the rocker arm during operation can be reduced. In some embodiments, the pivotable rod is a relatively flat rod extending in a main extension direction that, when in the mounted state, is substantially parallel to the adjacent housing portion of the combing device. In other words, in some embodiments, at least in the portion where the accessory component is attached in the mounted state, the main extension direction of the rocker arm is substantially parallel to the main extension direction of the attachment portion of the accessory component and the main extension direction of the combing device.

[0044] In some embodiments, the hinge axis intersects with at least one of one or more reinforcing ribs. In some embodiments, the hinge axis is offset inward from the inside of the pivotable rod. In either case, the design can contribute to a self-locking feature in the installed state.

[0045] In another exemplary embodiment, the brake nose has a main extension direction that is inclined relative to the hinge axis. This is particularly applicable when viewed in a side view, especially in a plane parallel to the hinge axis and parallel to the central longitudinal direction. In some embodiments, the main extension direction of the brake nose is also non-orthogonally inclined relative to the central longitudinal direction of the attachment and / or the combing device. The inclined main extension of the brake nose defines the position of the combing device relative to the attachment component in two directions in the mounted state. When, for example, two opposing rockers are used, the position of the combing device relative to the attachment component in the mounted state can be defined in three directions. However, it is also conceivable that the main extension of the brake nose is parallel to the hinge axis, provided that other measures are taken to define the mounted position of the combing device relative to the attachment.

[0046] In another exemplary embodiment, the attachment defines a central longitudinal direction, wherein the at least one rocker arm is pushed into the engaged position when a pull-out force, substantially parallel to the central longitudinal direction, acts on the brake nose. The pull-out force is directed away from the hinge axis. While the rocker arm is still in the engaged position, the pull-out force is typically applied to the combing device in an attempt to pull / remove the combing device from the attachment component. In this case, a self-locking feature prevents the combing device from loosening to avoid an undesirable operating state. When the rocker arm is actuated, the combing device can be removed from the attachment component with a relatively small pull-out force.

[0047] The self-locking feature ensures a secure connection between the combing equipment and accessory components during operation, even when undesirable pull forces are applied. Overall, this increases operational safety and prevents accidental detachment.

[0048] In another exemplary embodiment, the hinge axis is arranged at a first distance from the center in the longitudinal direction, while the brake nose is arranged at a second distance from the center in the longitudinal direction greater than the first distance.

[0049] This design creates a self-locking effect. The locking unit has a self-reinforcing characteristic when engaged. By actuating the rocker arm, the locking unit can be moved to the release position, which facilitates the separation of the combing device from the accessories.

[0050] In another exemplary embodiment, the brake nose has a contact surface facing the hinge axis, wherein, at least in the engaged position, the contact surface is arranged at an angle ranging from 88° to 105° relative to the central longitudinal direction. In this manner, self-locking capability can also be supported. When in the installed state, the contact surface contacts the combing device at the engagement groove. This angle further optimizes the self-locking feature, thereby ensuring reliable and durable attachment.

[0051] The main purpose of the self-locking design is that the pull-out force will not inevitably cause the brake nose to be pushed out of the engagement recess, but can be converted into a force / torque that pushes the brake nose into the engagement recess (due to the design of the locking unit).

[0052] In another exemplary embodiment, the locking unit includes two opposing rockers, each rocker having a brake nose, wherein the brake noses of the two opposing rockers are closer together in the engaged position than in the released position of the two opposing rockers. The two opposing rockers may be referred to as the left rocker and the right rocker. Having two or more rockers makes the connection more redundant and reliable. The locking unit can withstand even higher pull-out forces. Additionally, in the installed state, the two opposing rockers can accurately define the position of the combing device therebetween. The two opposing rockers can simultaneously enter the released position by pressing their release parts toward each other.

[0053] In another embodiment, the combing device has a housing that is tapered and / or V-shaped in the region adjacent to the rocker arm, with its wider side facing away from the socket provided by the accessory device. In this case, the combing device can be gently moved upon insertion, thus biasing the rocker arm to generate a biasing force that pushes the brake nose into the engagement groove.

[0054] In another exemplary embodiment, two opposing rockers are arranged on opposite sides of the attachment, and their respective release positions are achieved when the release portions of the two opposing rockers are pushed together to overcome a biasing force. This facilitates the separation of the combing device from the accessory component. The two rockers can be pressed together, causing them to move simultaneously to their respective release positions.

[0055] In another exemplary embodiment, the accessory component is a handle extension arranged to be attached to the combing device.

[0056] The attachment portion is releasably attachable to the original handle portion of the combing device to increase its operating range, and

[0057] The handle extension further includes a handle portion.

[0058] The handle extension extends the operating range of the grooming device to hard-to-reach areas of the body, such as the user's back. The grooming device can be used over a larger area and offers improved ease of use in hard-to-reach areas. In some embodiments, the handle extension may be referred to as a back handle attachment.

[0059] In another exemplary embodiment, a T-shaped handle is formed at the end of the handle portion, wherein when the accessory component is in the installed state, the T-shaped handle has a main extension direction that extends parallel to the width of the operating head of the combing device. In some embodiments, the main extension of the T-shaped handle is orthogonal to the (possibly curved) main extension direction of the handle extension.

[0060] The T-handle can be used to translate operating commands at the T-handle into corresponding movements at the front end of the handle extension, where the combing device is mounted. The T-handle can be elliptical in shape, cigar-shaped, and / or zeppelin-shaped.

[0061] It has been observed that operating and guiding the grooming device on the user's back and other hard-to-reach body parts is quite easy using the T-shaped handle located at the end of the handle. The T-shaped handle provides direct and easily understood tactile feedback to the user's hand. The maneuverability and controllability of the grooming device's operating head can be improved.

[0062] In yet another aspect of this disclosure, a combing apparatus is provided, the combing apparatus comprising:

[0063] - An accessory component according to at least one aspect or embodiment described herein,

[0064] - A grooming device configured to move along the user's skin, including:

[0065] - Original handle section,

[0066] - The operating head is arranged to contact the skin, and

[0067] - At least one mating recess,

[0068] The accessory component is configured to be releasably mounted to the combing device, and

[0069] When the accessory component is in the installed state, the brake nose of the at least one rocker arm engages with the at least one engagement recess.

[0070] Combing equipment can also be called combing kits, combing components, or combing sets.

[0071] In some embodiments, a handle extension is releasably attachable to the combing device, particularly to its original handle portion. The handle extension extends the operating range of the combing device to hard-to-reach areas of the body, such as the user's back. The combing device can be used over a larger area and offers improved ease of use in hard-to-reach areas.

[0072] In another exemplary embodiment, the combing device is a motor-driven hair-cutting device, wherein the operating head includes at least one motor-driven hair-cutting section configured to cut hair. For example, the combing device may be configured as a hair trimming device, a shaving device, and / or a combination of trimming / shaving devices.

[0073] The operating head can be configured as a cutting head with two or more cutting elements that can move relative to each other to cut hair. This can include a metal shaving section, a trimming section, etc. Needless to say, there can also be non-powered grooming devices, as well as non-powered hair cutting devices (e.g., razors).

[0074] As mentioned above, grooming equipment may also include other devices besides hair cutting devices. This can include epilators, massagers, etc. Similarly, accessory components may also include components other than the handle extension.

[0075] Based on the aspects and embodiments disclosed herein, an improved combing device and corresponding accessory components are proposed, which enhance user comfort and provide a reliable, accurate, secure, and releasable connection between the accessory components and the combing device.

[0087] Figure 1 A combing device 10 is shown, which includes a combing device 12 and an accessory component 38 for combing the device 10. Figure 1 In an exemplary embodiment, the combing device 10 is configured as a hair cutting device, which includes a hair cutting device 14 (as an exemplary embodiment of the combing device 12) and a handle extension 40 (as an exemplary embodiment of the accessory component 38). As described above, other embodiments of the combing device 12 and the accessory component 38 are possible.

[0088] although Figure 1 The separation state is shown, but the corresponding... Figure 2 The installation / attachment state is shown, in which the combing device 12 and accessory component 38 are coupled to each other.

[0089] The grooming device 12 can also operate without the accessory component 38 and includes a basic handle portion 16 that is gripped by the user in normal operating mode. Generally, the grooming device 12 includes a housing 18 that supports the operating head 20. In an exemplary embodiment, the grooming device 12 is configured as a hair cutting device 14, and the operating head 20 includes a cutting unit 22. The cutting unit 22 may include at least one of a trimming portion 24 and a metal blade shaving portion 26. Figure 1 In this context, the cutting unit 22 is a combined cutting unit including a trimming section 24 and a metal shaving section 26.

[0090] The width extension of the operating head 20 is indicated by arrow 28. For example, when the grooming device 12 moves along the user's skin, the width extension 28 is substantially perpendicular to the general direction of movement, such as when cutting hair there, see [reference needed]. Figure 2 Reference numeral 82 in the figures. Therefore, the width extension 28 is a reference to the preferred operating orientation of the combing device 12 and its operating head 20.

[0091] An operating controller, such as an operating switch 30, is disposed on the housing 18. The housing 18 houses the motor 32, which is located within... Figure 1 The dashed box indicates the location. Other components may be housed within the housing 18, such as batteries, power adapters, circuits, force transmission components, etc.

[0092] Typically, the combing device 12 can be a motor-powered and / or non-powered device. When the combing device 12 is arranged as a hair trimming device 14, the motor 32 causes at least one cutting element of the cutting unit 22 to move. This can include relative cutting motion between two cutting elements to cut hair between them. This can include shaving, trimming, haircutting, etc.

[0093] The operating head 20 is connected to the housing 18 at its neck 34. At least one engagement groove 36 is formed in the neck. The engagement groove 36 can engage with a corresponding portion of the accessory component 38 to ensure the installation state between the combing device 12 and the accessory component 38. The installation state is as follows: Figure 2 As shown.

[0094] In an exemplary embodiment, the accessory component 38 is arranged as a handle extension 40. For example... Figure 1 as well as Figure 3 As shown in the side view, the handle extension 40 may have an elongated extension including an integral bow shape, a boomerang shape, and / or a banana shape.

[0095] The handle extension 40 includes an attachment 42 at which the combing device 12 and the accessory component 38 are attached to each other. Figure 1 and Figure 2 As shown, the combing device 12 can be inserted into the front collar 44 of the attachment 42. Furthermore, the handle extension 40 includes a handle portion 46 located at the end opposite to the front collar 44. The handle portion 46 is part of the handle extension 40, where the user typically grasps and carries the combing device 10 formed by the handle extension 40 and the combing device 12 mounted thereon.

[0096] In an exemplary embodiment, attachment 42 provides a container 50 configured to receive and / or otherwise support the original handle portion 16 of the combing device 12. For example, the container 50 is defined by a wall 52, which may be a circumferential wall. In some embodiments, the container 50 provides a cylindrical and / or tubular seat for the housing 18 of the combing device 12.

[0097] The combing device 12 can be inserted into and retracted from the container 50 via the front collar 44. The double arrow 54 indicates the central longitudinal direction of the attachment 42. The central longitudinal direction 54 corresponds to the insertion / removal direction and also to the main extension of the combing device 12. A hole 58 is formed in the wall 52, through which the operating switch 30 can be accessed.

[0098] The accessory component 38 also includes a locking unit 60, which comprises one or more rocker arms 62. In an exemplary embodiment, two opposing rocker arms 62 are positioned near the front collar 44. This should not be construed as limiting. In an exemplary embodiment, the two rocker arms 62 face each other and are displaced relative to each other in the width extension 28 to engage the combing device 12 at two corresponding engagement recesses 36 that may be formed in the housing 18.

[0099] Locking unit 60 locks and secures the connection between the combing device 12 and the accessory component 38. For this purpose, rocker arm 62 can be actuated to move between an engaged position and a released position. In some embodiments, rocker arm 62 is designed such that self-locking occurs when the combing device 12 is inserted into the container 50 along its central longitudinal direction 54, causing the engagement groove 36 of the combing device 12 to be engaged by rocker arm 62, thereby ensuring coupling between the accessory component 38 and the combing device 12.

[0100] In some embodiments, forming Figures 1 to 4 The handle extension 40 of the accessory component 38 can be in the unfolded state (see...). Figure 1 ) and folded state (see Figure 3 Fold between ) . For example Figure 1 , Figure 3 and Figure 4 As shown, a folding mechanism 70 can be disposed between the handle portion 46 and the attachment portion 42. The folding mechanism 70 enables the handle extension portion 40 to fold / unfold between at least two states. In an exemplary embodiment, the folding mechanism 70 allows relative rotational movement between the attachment portion 42 and the handle portion 46 about a rotation axis 72. Figure 3 In the diagram, rotational motion is represented by a curved double arrow, indicated by 74.

[0101] exist Figure 3 In the image, the handle portion 46 is shown in a folded state with solid lines, while the unfolded state is shown with dashed lines. The handle extension portion 40 is elongated and arched (as shown in the image). Figure 1 (As shown). A slender, arched shape can also be called a banana shape and / or a boomerang shape. For example... Figure 4 As shown, the slender, arched shape is advantageous for shaving the user's back 80°. Therefore, a larger operating range is possible, and hard-to-reach parts of the body can be reached.

[0102] Refer again Figure 1 and Figure 3 An embodiment is described, wherein a T-shaped handle 76 is formed at one end of the handle portion 46, having a main extension direction 78 parallel to the width extension 28 of the operating head 20 of the combing device 12. The T-shaped handle 76 is formed at the end of the handle portion 46 opposite to the front collar 44 when the handle extension 40 is in an unfolded elongated arc shape.

[0103] The T-shaped handle 76 is advantageous for some applications, especially when there is only a limited view of the operating position. This is suitable, for example, when a user wants to shave their back 80, such as... Figure 4 As shown. Because the T-shaped handle 76 is oriented parallel to the width extension 28 and substantially perpendicular to the typical direction of movement of the combing device 12 along the user's skin (see... Figure 2 and 4As indicated by the double arrow in the attached drawing (reference numeral 82), operability and controllability are improved when the T-handle 76 directly transfers control movement to the front portion 44 of the combing device 12 and the operating head 20. Furthermore, the T-handle 76 improves tactile feedback because the user can infer the orientation of the operating head 20 from the orientation of the T-handle 76.

[0104] Further reference Figure 5 and Figure 6 The locking unit 60 is shown in more detail therein. Figure 5 A partial cross-sectional view is shown with the combing device 12 and the attachment portion 42 of the accessory component 38 in a separated state. More specifically, Figure 5 A cross-sectional perspective view of two opposing rocker arms 62 is shown.

[0105] Figure 6 A corresponding front perspective view of the front collar 44 of the attachment 42 without the combing device 12 installed is shown.

[0106] In an exemplary embodiment, the rocker arm 62 is integrally formed with a corresponding portion of the attachment 42. More specifically, the rocker arm 62 is integrally formed with the wall 52 of the container 50 defining the combing device 12. In some embodiments, the attachment 42 is a single component of the rocker arm 62 integrating the locking unit 60. In this way, a single injection molding component can provide both the container 50 and the locking unit 60 for the combing device 12. Each rocker arm 62 has an engagement portion 84 and a release portion 86.

[0107] At the joint 84, a brake nose 88 is formed that engages with the engagement groove 36 at the neck 34 of the combing device 12. Figure 7 and Figure 8 The image shows the engagement state, in which the brake nose 88 engages with the engagement recess 36.

[0108] like Figures 5 to 7 As shown, all rocker arms 62 can pivot about the hinge axis 90. In an exemplary embodiment, the engagement portion 84 and the release portion 86 are formed on opposite sides of the hinge axis 90.

[0109] In summary, the joystick 62 can be in an engaged position (e.g. Figure 8 and 9 (as shown) and release position (as shown) Figure 10 (As shown). In the engaged position, the brake nose 88 engages the engagement recess 36 and thus secures the combing device 12 at the attachment portion 42. In the released position, the brake nose 88 disengages from the locking recess 36, thus allowing the combing device 12 to detach from the accessory component 38.

[0110] By actuating the release part 86 of the rocker arm 62, the rocker arm 62 can move from the engaged position to the released position. See also Figure 5The box arrow 92 in the image indicates the actuation.

[0111] Figure 6 The rocker arms 62 are shown to be pivotable rods 96, each pivotable about a hinge axis 90. The pivotable rods 96 are relatively flat rods with a main extension substantially parallel to the central longitudinal direction 54. The rocker arms 62 (and therefore their pivotable rods 96) respectively have an inner side 98 facing the combing device 12 in the installed state and an outer side 100 away from the inner side 98.

[0112] The rocker arm 62 is formed in a cutout 104 in the wall 52 of the attachment portion 42. Figure 6 In this embodiment, the cutout 104 has a closed shape, so that the rocker arm 62 is completely surrounded by the wall 52. This provides a certain degree of protection for the rocker arm 62.

[0113] The rocker arm 62 can pivot within the cutout 104 about a hinge axis 90. In an exemplary embodiment, the hinge axis 90 is formed by a movable hinge 106 integrally formed with the wall 52. The movable hinge 106 provides a defined hinge axis 90 on the one hand. On the other hand, due to the inherent drag torque of the movable hinge 106 as it deforms when the rocker arm 62 pivots, the movable hinge 106 can generate a certain biasing force. Therefore, any pivoting movement deviating from the neutral position generates a certain biasing force in the movable hinge 106, which tends to push the rocker arm 62 back to the neutral position.

[0114] exist Figures 5 to 8 In the illustrated embodiment, a movable hinge 106 is formed on the inner side 98 of the rocker arm 62. In other words, a rolled edge is formed on the inner side 98 of the rocker arm 62 and connects to an adjacent portion of the wall 52. The longitudinal extension of the rolled edge defines a hinge axis 90. In some embodiments, one or more reinforcing ribs 108 are formed on the inner side 98 of the rocker arm 62. The reinforcing ribs 108 provide increased stiffness and rigidity to the rocker arm 62, particularly in terms of pivoting motion about the hinge axis 90. In an exemplary embodiment, the rolled edge forming the movable hinge 106 extends through the reinforcing rib 108. The reinforcing rib 108 has a main extending direction substantially parallel to the central longitudinal direction 54.

[0115] Figure 8 A partial cross-sectional view is shown of the combing tool 12 mounted on the accessory component 38, wherein... Figure 7 The dashed lines VIII-VIII in the diagram indicate the cross section.

[0116] like Figure 7 As shown, the brake nose 88 at the joint 88 of the rocker arm 62 (see...) Figure 5(6 and 8) have a main extension direction 110 inclined at an angle 112 relative to the hinge axis 90. As an example, the angle 112 is in the range of 20° to 45°. Thus, the brake nose 88 has a design and main extension 110 adapted to the shape of the neck 34 of the combing device 12. Furthermore, the angle 112 between the hinge axis 90 and the brake nose 88 has the effect that the position of the combing device 12 in the container 50 can be limited in more than one direction. If the main extension direction 110 is parallel to the hinge axis 90, then the relative position between the combing device 12 and the rocker arm 62 can only be limited in one direction (i.e., along the central longitudinal direction 54).

[0117] Figure 8 Two opposing rockers 62 are shown securing the combing device 12 between them by engaging corresponding opposing engagement grooves 36 at the neck 44. In summary, the position of the combing device 12 in the installed state can be precisely defined in three directions.

[0118] exist Figure 8 The diagram shows a central axis 114 passing through the attachment portion 42 and the combing device 12. The central axis 114 may be an axis of symmetry. In an exemplary embodiment, the central longitudinal direction 54 is parallel to the central axis 114.

[0119] Figure 9 and Figure 10 The corresponding half-view shows Figure 8 A schematic diagram of the device is provided to illustrate the operating principle of the locking unit 60, which has two rocker arms 62. Figure 9 and Figure 10 In the center, the central axis 114 forms the reference for each half-view.

[0120] like Figures 8 to 10 As shown, the combing device 12 is generally V-shaped or conical, at least near the rocker arm 62 of the locking unit 60. In other words, the combing device 12 is V-shaped or tapers towards the corresponding original handle portion 16 of the combing device 12 (see...). Figure 1 The effect of this is that when the combing device 12 is inserted into the container 50, the housing 18 can move the rocker arm 62 with its brake nose 88 until the brake nose 88 can engage the engagement recess 36. Due to the displacement of the rocker arm 62, a biasing force can be generated to push the brake nose 88 into the engagement recess 36.

[0121] In some embodiments, the locking unit 60 provides a load-amplifying self-locking feature. The rocker arm 62 is arranged such that the hinge axis 90 is located at a first distance 118 from the central axis 114, while the brake nose 88 is located at a second distance 120 from the central axis 114, greater than the first distance 118. The second distance 120 spans between the central axis 114 and the contact surface 124 of the brake nose 88 facing the hinge axis 90.

[0122] Furthermore, in some embodiments, the contact surface 124 is arranged at an angle 126 relative to the central axis 114. For example, the angle 126 can be in the range of 88° to 105°. That is, the contact surface 124 is substantially perpendicular to the central axis 114.

[0123] By adjusting the positions of the rocker arm 62 and the brake nose 88 relative to the central axis 114, a pull-out force 130 parallel to the central axis 114 and / or the central longitudinal direction 54 will not cause the brake nose 88 to disengage from the engagement recess 36, but will instead generate a retaining force or torque 132 that causes the brake nose 88 to enter the engagement recess 36. Therefore, if the rocker arm 62 is in the engaged position (e.g., ...), Figure 9 When the user applies a pulling force 130 to the combing device 12 (as shown), unwanted loosening of the combing device 12 is prevented.

[0124] exist Figure 9 In the arrangement shown, the rocker arm 62 has a tendency to rotate counterclockwise. The opposite rocker arm 62 (in...) Figure 9 (Not shown in the half-view) will have a tendency to rotate in a clockwise direction. In summary, the two rockers 62 can cooperate to apply a load amplification self-locking feature, which secures the combing device 12 in its mounting position at the accessory component 38 and prevents unwanted loosening.

[0125] like Figure 10 As shown, the combing device 12 can be easily disassembled in the released position of the rocker arm 62. For this purpose, the rocker arm 62 can be actuated at the release section 86 (see...). Figure 10 (See arrow 92 in the box), thereby overcoming the inherent bias force 138 of the joystick 62 in the corresponding position, also see Figure 10 The pivoting motion of the pivotable rod 96, which forms part of the rocker arm 62, about the hinge axis 90. Figure 10 It is indicated by a curved arrow marked 144.

[0126] A brake nose 88 is formed at the inner side 98 of the pivotable lever 96, the brake nose 88 being arranged to engage the engagement recess 36. The rocker arm 62 can be actuated at the corresponding outer side 100, see [reference needed]. Figure 10 The actuation arrow 92 in the middle.

[0127] Figure 9and Figure 10 The normal (vector) 150 on the contact surface 124 facing the hinge axis 90 is also shown. The normal 150 passes through the hinge axis 90 in an outward offset away from the central axis 114. This is particularly applicable to the portion of the contact surface 124 facing the hinge axis 90, and when in the engaged position (see...). Figure 9 When the engagement recess 36 is actually engaged, the accessory component 38 is secured there. This design ensures that when a pulling force 130 is applied, the rocker arm 62 with the brake nose 88 is pushed into the engagement position.
