Description

Technical Field

[0001] The present invention relates to a cutting head having a handle with a motor and a blade unit having first and second blades for cutting hair, the blade unit being driven by the motor such that at least one of the first and second blades reciprocates in a reciprocating motion direction with respect to the other, the cutting head having a first snap-fit connector, and a comb attachment removably attachable to the cutting head, the comb attachment having a second snap-fit connector provided to engage with the first snap-fit connector by a snap-fit connection for attaching the comb attachment to the cutting head, and relates to a hair removal device, particularly an electric shaver or a hair trimmer.

Background Art

[0002] In hair removal devices such as beard trimmers, the shape and / or length of the beard can typically be trimmed. To adjust the length of the hair to be cut, a distance comb is provided that cooperates with the cutting edge and adds more distance between the cutting edge and the skin surface. Other attachments can be used to ensure, for example, that the sharp cutting edge is safely separated from the thin perceptible skin area. These attachments are removably attached to the cutting head of the hair trimmer or electric shaver and are exchanged with each other according to the desired application. The attachment is attached to the cutting head by a latch, hook, snap-fit or other type.

[0003] Existing snap-fit connections have been troubled by the problem of adding a large bulk to the overall dimensions and / or have been found to be inadequately handled. The snap-fit connection itself may seem like a fairly simple way to connect components, but when this is combined with the fairly unintuitive or cumbersome attachment and removal of the comb from the cutting head, the plastic parts to be attached may be damaged at their connections first.

Summary of the Invention

Means for Solving the Problems

[0004] The underlying object of the present invention is to provide an improved hair removal device that avoids at least one of the drawbacks of the prior art and / or further develops existing solutions. A more specific object underlying the present invention is to provide a hair removal device having an improved snap-fit connection between the cutting head and the comb attachment.

[0005] This object is achieved by a cutting head having a handle with a motor and a blade unit provided with first and second blades for cutting hair, the blade unit being driven by the motor such that at least one of the first and second blades reciprocates in a reciprocating movement direction relative to the other, the cutting head having a first snap - fit connector, and a comb attachment removably attachable to the cutting head, the comb attachment having a second snap - fit connector provided to engage with the first snap - fit connector by a snap - fit connection for attaching the comb attachment to the cutting head, the first snap - fit connector being formed in a shape that bends, made of a material that bends, or supported to bend, at least one of which is such that the first snap - fit connector can bend when engaged with the second snap - fit connector. The bending configuration of the first snap - fit connector can be achieved by a thinner material thickness in the region of the snap - fit protrusion or by the external shape of the surrounding region that allows bending. An example of a bending material is rubber or TPE (thermoplastic elastomer) in the surrounding region of the snap - fit or the protrusion itself. The first snap - fit connector may additionally or alternatively be supported to bend. In this case, the snap - fit protrusion may be provided on a wall element that is not connected to the remainder of the housing on at least some sides such that at least one or more slots or free spaces are formed adjacent to the snap - fit protrusion. The lack of connection to such other housing parts can form, for example, a bending tongue on which the snap - fit protrusion is provided. All these and other possibilities that enable the first snap - fit connector to bend may be provided alternatively or in combination. It should be noted that such a snap - fit connection may be provided by an attachment other than the comb attachment.Furthermore, in the context of the present invention, the terms "first snap-fit connector" and "second snap-fit connector" can refer to at least one of each of such first and second snap-fit connectors, but also include two, three, or more pairs of the first and second snap-fit connectors.

[0006] This configuration of the first snap-fit connector provided on the cutting head that bends provides several advantages. Usually, giving flexibility to a snap-fit connector would result in increasing its thickness or bulk in order to be able to distinguish between the bending wall and the wall that is not desired to bend. The cutting head provided sufficient space for this without adding anything to the dimensions of the comb attachment.

Modes for Carrying Out the Invention

[0008] According to an advantageous aspect, the comb attachment 10 has at least one row of comb teeth on the front side portion 13, the upper skin side portion 14, the inner hair cutting head coupling side portion 15, and at least one lateral side portion 16a, 16b. At least one lateral side portion 16a, 16b has wall portions 18a, 18b. On one side of the wall portions 18a, 18b, finger gripping regions 17a, 17b are provided, and on the opposite side of the wall portions 18a, 18b, second snap - fit connectors 11a, 11b are provided, so that finger gripping regions 17a, 17b are formed on the outside and a second snap - fit connector 11 is formed on the inside. Thus, the finger gripping portion for attaching and detaching the comb to and from the cutting head is in the same region as the region where the second snap - fit connector is provided (provided only on the opposing side portions of the same wall portion of the comb attachment). Usually, when fingers simultaneously press the snap - fit connection while gripping the attachment, it is difficult to release the snap - fit connection without adding a further design mechanism.

[0009] According to another aspect of the depilatory device, the comb attachment 10 has two lateral side portions 16a, 16b on opposite sides of each other, and each of the two lateral side portions 16a, 16b has wall portions 18a, 18b. Each of the wall portions 18a, 18b has finger gripping regions 17a, 17b on the outside and second snap - fit connectors 11a, 11b on the opposing inside. Thus, the comb attachment is not clamped onto the cutting head 4 when the lateral side portions are gripped or pressed together to remove the comb 10.

[0010] The second snap - fit connectors 11a, 11b are formed in a shape with lower flexibility, made of a material with lower flexibility, or supported with lower flexibility, compared to the first snap - fit connectors 9a, 9b, and are at least one of these. According to an example related to this, the second snap - fit connector is rigid with respect to the comb, or has no flexibility, or at least has low flexibility (compared to the flexibility provided by the material, shape, or support of the first snap - fit connector), so that no additional space is added to the width of the comb to provide a bending structure, enabling a design of an elongated lateral side portion.

[0011] Furthermore, one or more second snap - fit connectors 11a, 11b include protrusions 19a, 19b protruding from wall portions 18a, 18b, and the wall portions 18a, 18b include guide rail protrusions 20a, 20b aligned adjacent to the protrusions 19a, 19b of the second snap - fit connectors 11a, 11b. Thus, both the protrusions 19a, 19b of the second snap - fit connectors 11a, 11b and the guide rail protrusions 20a, 20b function to guide the comb attachment 10 at its inner lateral side portions during attachment to the cutting head 4. According to one aspect, the guide rail protrusions 20a, 20b are provided on the wall portions of both opposing lateral sides of the comb attachment 10, regardless of whether the term is called in the singular or plural. As a result, preferably, lip - shaped guide rail protrusions 20a, 20b are arranged adjacent to each of the snap - fit protrusions of the second snap - fit connectors 11a, 11b. Therefore, when attaching the comb attachment 10 to the cutting head 4, both the snap - fit protrusions and the guide rail protrusions of the second snap - fit connectors serve to guide the comb within the sliding path.

[0012] The comb attachment 10 is provided to be attachable to the cutting head 4 in a direction 21 that is angled or perpendicular to the reciprocating motion direction 8. The direction 21 is defined by the aforementioned sliding path along which the comb attachment 10 slides during attachment.

[0013] The cutting head 4 includes an upper skin side portion 21, at least one row of teeth 6a, 7a at the front end portions 23 of each of the first and second blades 6, 7, and at least one lateral side portion 24a, 24b provided with the first snap-fit connectors 9a, 9b.

[0014] According to one aspect of the hair removal device, the cutting head 4 is provided with two opposing lateral side portions 24a, 24b, and each of the lateral side portions 24a, 24b is provided with the first snap-fit connectors 9a, 9b. Having a pair of the first snap-fit connectors 9a, 9b ensures a safer connection of the comb to the cutting head 4.

[0015] According to another aspect of the hair removal device, depressions 25a, 25b are provided in at least one of the side surfaces 24a, 24b of the cutting head 4, and the first snap-fit connectors 9a, 9b protrude from the depressions 25a, 25b. Similar to the guide rail protrusions and the other features described in relation to one side portion of the cutting head and the comb attachment, the same mechanism is provided on the other opposing side portion as well. Thus, when referring to only one of the lateral side portions, the other side portion has the same structure, regardless of being in the singular form. Therefore, the crack of the guide rail protrusion is guided along a path defined by the depression of the cutting head 4.

[0016] Furthermore, the hair removal device includes at least one recess 25a, 25b shaped as a longitudinal guide groove for guiding the second snap - fit connectors 11a, 11b during attachment of the comb attachment 10 to the cutting head 4. The comb attachment and the cutting head comprise a cooperating key and slot structure that enables guided attachment of the comb attachment 10 onto the cutting head 4 until the first snap - fit connector and the second snap - fit connector engage with each other. This facilitates handling of the attachment and removal process and avoids twisting of the snap - fit connectors during the process.

[0017] According to one aspect, the hair removal device comprises first snap - fit connectors 9a, 9b supported by bending tongues 26a, 26b respectively. Thus, each of the first snap - fit connectors is supported bendably and / or shaped bendably by a bending tongue.

[0018] The hair removal device according to any of the preceding claims, wherein each of the first snap - fit connectors 9a, 9b is surrounded by at least one slot 27a, 27b, in particular two opposing slots 27a, 27b, to enable the first snap - fit connectors 9a, 9b to be pushed down or moved when pushed by the second snap - fit connectors 11a, 11b during attachment of the comb attachment 10. Thus, the first snap - fit connectors are provided on a beam of a curved wall portion or a bending tongue by connection to the cutting head housing at the slots 27a, 27b on two opposing short sides and two long sides. This ensures good flexibility of the first snap connectors without using components of different materials.

[0019] The two first snap - fit connectors 9a, 9b move or bend towards each other during the connection of the comb attachment 10. More preferably, the moving or bending direction 29 of the two first snap - fit connectors 9a, 9b substantially corresponds to the reciprocating motion direction 8. During the engagement with the second snap - fit connector of the comb attachment, only the first snap - fit connector substantially moves. The moving direction of the protrusion of the first snap - fit connector is parallel to or slightly inclined with respect to the reciprocating motion direction of the movable blade.

[0020] The first snap - fit connectors 9a, 9b are integral with the cutting head housing 30. Thus, the first snap - fit connectors are formed by the same parts as the cutting head housing, and therefore, it is possible to manufacture this plastic part by an injection - molding process.

[0021] According to a further aspect, a hair - removal kit is provided. The hair - removal kit includes the hair - removal device according to the present invention and another comb attachment 10 that can be detachably attached to the cutting head 4. The other comb attachment is provided with the (same) second snap - fit connectors 11a, 11b that engage with the first snap - fit connectors 9a, 9b by a snap - fit connection for attaching the other comb attachment to the cutting head 4. Thus, more combs or other attachments may be provided with a snap - fit connection structure corresponding to the snap - fit connection structure of the comb attachment 10 so that different attachments can fit into the same snap - fit connection structure of the cutting head 4.

[0022] Figure 1 shows a perspective view of a body-and / or beard hair trimming device 1 having a handle 2 and a cutting head 4 that can be releasably connected to the handle or permanently connected to the handle 2. The handle 2 is provided with an on / off button 31 for switching on and off a motor 3 provided inside the handle 2. The motor 3 includes a drive shaft having an eccentric portion connectable to a cam 32 (see FIG. 3) of the cutting head 4. The handle 2 may further include a rotary wheel 33 or other means for adjusting the hair trimming length.

[0023] A comb attachment 10 is removably attached to the upper end of the cutting head 4. The hair trimming length can be adjusted by the adjustment wheel 33 and / or by attaching different comb attachments 10 provided for specific hair trimming needs or different desired hair cutting lengths to the cutting head.

[0024] FIGS. 2 and 3 show the cutting head 4 with the comb attachment 10 removed. The hair cutting head 4 has a cutting head housing 30 made of plastic and a blade unit 5. The lower part 34 of the housing 30 is provided as a connection area to the handle 2. The upper part 35 of the housing 30 is visible when the cutting head 4 is connected to the handle 2. The housing 30 is a hollow part whose upper end is closed by a stationary blade 6 of the blade unit 5. The stationary blade 6 can be made of full metal or plastic with metal teeth. In this case, the stationary blade 6 is connected to the cutting head 4 by screws 36, but other connections are equally possible.

[0025] Another part of the blade unit 5 is the movable first blade 7, which engages with the eccentric part of the motor-driven shaft and reciprocates in the direction 8 (see Fig. 1) back and forth laterally with respect to the non-movable stationary second blade 6 when the motor 3 is operating, in cooperation with the cam 32. This moving direction 8 is parallel to the hair cutting edge formed by the tooth tips 6a, 7a of the stationary and / or movable blades. Both blades 6, 7 have a row of hair cutting teeth at their front ends.

[0026] Figs. 4, 5 and 6 show the comb attachment 10 from different viewpoints, in which the upper skin contact side is shown as the lower side. A plurality of additional protruding hair combing lips 40 are provided on this skin contact side 14.

[0027] The comb attachment 10 is formed like a sleeve shaped to cover the cutting head 4 such that the inner connecting side 15 is close to or in contact with the skin side 21 of the cutting head 4. The comb attachment has a front side 13 which is the side that first contacts the hair to be combed and cut when the device is moved in the direction 39 which is the extension of the longitudinal comb teeth 41. The comb teeth 41 are aligned in a row and at least partially cover the tooth row of the blade unit 4. (see Fig. 1).

[0028] Perpendicular to and laterally with respect to the front side portion 13 having the comb teeth of the comb attachment 10, two lateral side portions 16a, 16b having wall portions 18a, 18b are provided. These wall portions 18a, 18b have inner portions facing each other, and the inner portions are respectively provided with protruding portions 19a, 19b that function as the second snap-fit connectors 11a, 11b. The snap-fit protruding portions 19a, 19b are formed with a substantially U-shaped or substantially V-shaped cross-section. In alignment with these snap-fit protruding portions 19a, 19b, longitudinal lip-shaped guide rail protruding portions 20a, 20b are also provided inside the wall portions 18a, 18b. On each opposite side of the wall portions 18a, 18b, finger gripping regions 17a, 17b are provided outside rather than inside the lateral side portions. The finger gripping regions 17a, 17b may optionally be provided with a structure for strengthening the grip, or may simply be flat and without a gripping texture. The lateral side portions 16a, 16b and the wall portions 18a, 18b are substantially rigid. Since the second snap-fit connectors 11a, 11b do not require a bending structure, the lateral side portions 16a, 16b do not add much thickness, and thus the comb attachment is not very bulky.

[0029] Figures 7 and 8 show the housing 30 of the cutting head 4 or a part thereof. The cutting head 4 has two lateral sides 24a, 25b, each of which has a substantially V-shaped or U-shaped protrusion forming a first snap-fit connector 9a, 9b. The snap-fit connectors 9a, 9b are supported on longitudinal tongues 26a, 26b, which are connected to the remainder of the housing 30 only at their short sides. Thus, there are slots 27a, 27b on both long sides of each of the tongues 26a, 26b, so that the tongues are easily bent and curved when there is a substantially pushing force in a direction 29 that is perpendicular to the longitudinal extension of the tongues. This bending ensures that both the first snap-fit connector and the second snap-fit connector can engage and disengage with each other during the attachment and removal of the cam 10. The upper second slots 27a, 27b are formed by the gaps between the first stationary blade 6 and the tongues 26a, 26b of the housing as shown in FIG. 2.

[0030] As shown in FIGS. 7 and 8, the first snap-fit connectors 9a, 9b and their supporting tongues 26a, 26b are recessed with respect to the surrounding housing 30 of the cutting head 4. Further, since the width spread of the second stationary blade 6 is larger than the width spread of the first snap-fit connector and the tongue supporting it, these snap-fit parts are also recessed with respect to the second blade 6. As a result, grooves or recesses 25a, 25b are formed, into which the first snap-fit connectors slightly protrude.

[0031] The comb attachment 10 is attached to the cutting head 4 in a direction 21 that corresponds to the moving direction 39 of the device for trimming hair and that is substantially perpendicular to the reciprocating movement direction of the hair cutting edge formed by the tips of the teeth of the first blade and / or blade unit 5. When sliding the comb attachment 10 onto the cutting head 4, the inner side 15 of the comb attachment 10 slides on the skin surface 21 of the second blade 6. Further, at the lateral side portions of the comb attachment, the comb is slidably engaged with the protrusions 19a, 19b of the second snap-fit connector and the subsequent guide rail protrusions 20a, 20b along the grooves or depressions 25a, 25b of the cutting head, whereby the comb is sleeved onto the cutting head 4. When slightly pushing in the direction 21 while holding the comb 10 in the gripping region, the first snap-fit connectors 9a, 9b bend away in a direction 29 perpendicular to the sliding direction 21 of the comb attachment. The gripping region of the comb attachment 10 is substantially rigid and the first snap-fit connectors of the cutting head can bend, so that when a finger grips the comb attachment 10, the first snap-fit connectors bend in the same direction 29 and in the same regions 17a, 17b, but similarly the contact force due to finger gripping in the direction 29 does not cancel or interfere with the smooth engagement or disengagement of the snap-fit connection.
