Description

Technical Field

[0001] The present disclosure relates generally to devices for hair removal, and more particularly to devices for back hair removal. Background Art

[0002] The discussion of shortcomings and needs in the art prior to the present disclosure is in no way an admission that those skilled in the art recognized such shortcomings and needs prior to the present disclosure.

[0003] Hair on the body grows in many directions, with hairs adjacent to or in close proximity to each other, often growing in very different directions. Today's wet razors require the blades to approach the hairs in a specific direction to ensure they are effectively cut. Hairs cut by the blade traveling in the direction opposite to the direction of growth (commonly known as an upstroke) are cut more closely and more consistently than hairs cut by the blade traveling perpendicular to the direction of hair growth. To compensate for this shortcoming, the user needs to make a large number of strokes in multiple directions to ensure that all hairs are effectively removed. Another shortcoming of today's wet razors is that they must only be used to perform strokes perpendicular to the direction of the blade edge to ensure that the blade does not slicing relative to the skin, as this can cause cuts and nicks. When shaving hard-to-reach areas of the body (such as the back), it can be particularly difficult to ensure that the blade does not move sideways relative to the skin. This results in the user having to expend a lot of energy trying to maintain a linear stroke, or having to ask a third party to help them remove the hair, or the user having to compromise on the safety of their shaving.

[0004] The blades guarded by the comb will likely reduce the risk of nicks and cuts caused by any slicing motion of the blades, but has the undesirable effect of limiting how close to the skin the hairs can be cut.

[0005] Electric dry foil razors have the advantage that they can be used safely in any direction on the skin and their hair removal efficiency is less affected by the direction of movement relative to the hair, however, they do not cut hair as close to the skin as wet razors.

[0006] The combination of a hair removal surface such as a foil and a pivot typically found in hair removal devices is typically rigid and inflexible, allowing movement in only one direction, thereby encouraging the user to make linear strokes during use, and this limitation forces the user to expend energy and compensate for poor ergonomics in the way they hold and angle the product. Thus, even if an improved cutting edge is implemented in a product, the product does not allow the user to fully benefit.

[0007] To ensure effective and efficient hair removal, it is crucial that the hair removal surface maintains good contact with the skin. This is easy to achieve on large, flat surfaces, but is more difficult when removing hair from contoured parts of the body, such as the back, knees, underarms, or shoulders. Many hair removal devices attempt to improve contact between the hair removal surface and the skin by allowing the hair removal surface to pivot. However, the pivots in current hair removal products are limited to deflection about one or two axes, which limits the ability of the hair removal surface to reorient itself to improve contact with the skin.

[0008] Hair removal surfaces used for shaving in multiple directions are subject to forces in multiple directions, and if the edge of the hair removal surface or applicator gets caught or hooked on the skin, for example due to high friction areas or on extreme contours of the body (e.g., shoulder blades), these forces can cause the hair removal surface to topple over from the skin. If this happens and the hair removal surface / applicator is flipped or tilted, it can lead to undesirable effects such as the underside edge of the applicator scraping the skin and reduced hair removal efficiency because the hair removal surface is no longer in contact with the skin.

[0009] Therefore, a need has been identified for a hair removal device that encourages unrestricted, multi-directional use. Summary of the Invention

[0010] The various examples disclosed herein address the aforementioned problems by providing a device that enables multi-directional deflection of a hair removal surface to facilitate unrestricted, multi-directional use, particularly when shaving back or body hair.

[0011] The present invention relates to a hair removal device comprising a plurality of leaf springs coupled to an applicator head, wherein the applicator head has a hair removal surface.

[0012] In one embodiment, a plurality of leaf springs are connected to form a wave spring. The wave spring comprises stacked wave washers.

[0013] In other embodiments, a plurality of leaf springs extend radially from the center of the hair removal surface, the plurality of leaf springs extending circumferentially around the periphery of the hair removal surface.

[0014] In other embodiments, the plurality of leaf springs are connected to each other.

[0015] Furthermore, each of the plurality of leaf springs may have the same or different sizes.

[0016] According to some examples, each of the plurality of leaf springs has a deflection stiffness ranging from 0.05 N / mm to 5 N / mm.

[0017] In various embodiments, the present invention relates to a hair removal device comprising a wave spring. The wave spring is coupled to an applicator head, wherein the applicator head comprises a hair removal surface. The wave spring extends circumferentially around a periphery of the hair removal surface. The wave spring has a width of 1 mm to 100 mm.

[0018] According to various examples, the wave spring is circular and may have a diameter and a thickness, and wherein the diameter is between 1 and 10 times the thickness.

[0019] Furthermore, the wave spring has a deflection stiffness ranging from 0.05 N / mm to 5 N / mm.

[0020] According to various examples, a hair removal device may include a base, a multi-angle deflector coupled to the base, an applicator head coupled to the multi-angle deflector, and a hair removal surface coupled to the applicator head. The hair removal surface may include a plurality of closed, non-linear cutting edges. The multi-angle deflector may be adapted to provide a multi-directional deflectable connection between the applicator head and the hair removal surface relative to the base.

[0080] It should be understood that the various embodiments are not limited to the examples shown in the drawings. DETAILED DESCRIPTION

[0081] Introduction and Definitions

[0082] This disclosure is written to describe the present invention to those of ordinary skill in the art, and those of ordinary skill in the art will understand that the disclosure is not limited to the specific examples or embodiments described. The examples and embodiments are single instances of the present invention, which will make the greater scope apparent to those of ordinary skill in the art. Unless otherwise defined, all technical terms and scientific terms used herein have the same meaning as those commonly understood by those of ordinary skill in the art. It should also be understood that the terms used herein are not merely for the purpose of describing the examples and embodiments, and are not intended to be limiting, as the scope of the present disclosure will be limited only by the appended claims.

[0083] Unless otherwise expressly stated, all features disclosed in this specification (including any accompanying claims, abstracts and drawings) may be replaced by alternative features for the same, equivalent or similar purposes. Therefore, unless otherwise expressly stated, each feature disclosed is only an example of a general series of equivalent or similar features. The examples and embodiments described herein are for illustrative purposes only, and those of ordinary skill in the art will propose various modifications or changes based on these examples and embodiments, and these modifications or changes will be included in the spirit and scope of this application. Without substantially departing from the spirit and principles of the present disclosure, many changes and modifications can be made to the embodiments of the present disclosure. All such modifications and changes are intended to be included within the scope of the present disclosure herein. For example, unless otherwise indicated, the present disclosure is not limited to specific materials, reagents, reaction materials, manufacturing processes, etc., because they can vary. It should also be understood that the terms used herein are only used to describe the purpose of specific embodiments and are not intended to be limiting. It is also possible in the present disclosure that steps can be performed in different orders that are logically possible.

[0084] All numerical values ​​herein are assumed to be modified by the term "about," whether or not explicitly stated. The term "about" generally refers to a range of values ​​that one skilled in the art would consider equivalent to the stated value (e.g., having the same function or result). In many cases, the term "about" may include values ​​that are rounded to the nearest significant figure.

[0085] In everyday usage, indefinite articles (such as "a") precede countable nouns, and uncountable nouns almost never take indefinite articles. Therefore, it must be noted that, as used in this specification and the claims that follow, the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to "a carrier" includes a plurality of carriers. In particular, when a singular countable noun is listed as an element in a claim, this specification will typically use phrases such as "single." For example, "a single carrier."

[0086] Where a numerical range is provided, it is understood that every intervening value, to the tenth of the unit of the lower limit unless the context clearly dictates otherwise, between the upper and lower limits of that range, as well as any other stated or intervening values ​​in the stated range, is encompassed within the disclosure. The upper and lower limits of these smaller ranges may independently be included in the smaller ranges and are also encompassed within the disclosure, subject to any specifically excluded limit in the stated range. Where the stated range includes one or both of the limits, ranges excluding one or both of those included limits are also encompassed within the disclosure.

[0087] Throughout this specification and the claims that follow, reference will be made to a number of terms that are defined to have the following meanings, unless a contrary intention is apparent.

[0088] "Disposed on" refers to a positional state indicating that one object or material is arranged in a position adjacent to that of another object or material. The term does not require nor exclude the presence of intervening objects, materials, or layers.

[0089] "Align," "aligned," or "align" means to place or arrange in a straight line. Thus, aligning the edges of substrates means arranging the substrates so that the edges in question extend along substantially the same line. It will be appreciated that aligning the edges of substrates can be achieved in a variety of ways, including placing one substrate on top of another or placing the substrates side by side.

[0090] "Facing relationship" refers to the relative positioning of materials (such as substrates) with a surface of one material oriented toward a surface of another material. For example, when two substrates are stacked one on top of the other, they are in a facing relationship. The term does not require nor exclude the presence of intervening objects, materials, or layers.

[0091] "Coupled" refers to the state of being linked or connected, indicating that one object or material is linked or connected to another object or material. The term does not require or exclude the presence of intervening objects, materials, or layers.

[0092] "Link" when used as a verb means to link or connect the linked objects with an intermediate object.

[0093] "Perimeter" means the smallest circle lying in a plane normal to the alignment axis that completely surrounds all parts of the structure.

[0094] Various examples

[0095] Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 61 and 2 illustrate a hair removal device 100 comprising a base 402, a multi-angle deflector 500 in the form of a wave spring 502, and an applicator head 600 comprising a hair removal surface 602. The applicator head 600 may support and / or surround the hair removal surface 602. Details regarding the multi-angle deflector 500 and the applicator head 600 will be discussed below.

[0096] Figure 1 A schematic bottom perspective view of the hair removal device 100 in a fully assembled state is provided, and Figure 2 A schematic top perspective view of the hair removal device in a fully assembled state is provided. The hair removal device 100 shown is configured as a handheld or palm-held unit. As used herein, the terms "handheld" or "palm-held" imply a structure having a size suitable for grasping and manipulating with a single hand. The base 402 includes a strap opening 416 through which a strap (not shown) can be inserted. The strap can be used to secure the hair removal device 100 to the user's hand. The strap can employ a connecting device, such as a hook and loop fastener, a snap, or a buckle. The strap can be elastic to provide a comfortable and secure fit with the user's hand. It should be understood that various additional configurations of the base 402 are possible. The base 402 may also include one or more central openings 408, which may facilitate rinsing, as will be discussed in more detail below. As Figure 2 As shown, the base 402 and / or any associated straps may constitute the handheld portion 103 of the hair removal device. Other versions of the handheld portion 103 are possible, some of which are discussed below.

[0097] Figure 3 A schematic exploded top perspective view of the hair removal device 100 is provided, and Figure 4 A schematic exploded bottom perspective view of the hair removal device is provided. Figure 3 and Figure 4As shown, the base 402, the multi-angle deflector 500, and the applicator head 600 are aligned along the alignment axis 700. The multi-angle deflector 500 may include a deflector-applicator connecting portion 530. Similarly, the applicator head 600 may include an applicator-deflector connecting portion 614. The deflector-applicator connecting portion 530 and the applicator-deflector connecting portion 614 may be adapted to permanently or releasably couple the multi-angle deflector 500 to the applicator head 600. The deflector-applicator connecting portion 530 and the applicator-deflector connecting portion 614 may include any suitable connection mechanism, such as, for example, a snap, threads, or magnets. An adhesive may also be applied to the deflector-applicator connecting portion 530 and / or the applicator-deflector connecting portion 614 to adhere the multi-angle deflector 500 to the applicator head 600. Additionally, the multi-angle deflector 500 may include a deflector-base connection portion 520, and the base 402 may include a base-deflector connection portion 404, which may be adapted to permanently or releasably couple the multi-angle deflector 500 to the base 402. The deflector-base connection portion 520 and the base-deflector connection portion 404 may include any suitable connection mechanism, such as, for example, snaps, threads, or magnets. Adhesive may also be applied to the deflector-base connection portion 520 and / or the base-deflector connection portion 404 to adhere the multi-angle deflector 500 to the base 402. As a non-limiting example, the base-deflector connection portion 404 may include female threads, and the deflector-base connection portion 520 may include corresponding male threads.

[0098] Figure 5 A schematic top view of the base 402 of the hair removal device 100 including the strip opening 416 is provided, and Figure 6 A schematic bottom view of the base is provided. Figure 5 As shown, the base surrounding perimeter 411 can surround the base 402 in a plane perpendicular to the alignment axis 700. The base surrounding perimeter 411 can be the smallest circle that completely surrounds the base 402. The base surrounding perimeter 411 can lie in a plane orthogonal to the alignment axis 700.

[0099] Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 The applicator head 600 and the hair removal surface 602 are shown in cooperation. Figure 7 A schematic bottom view of an applicator head 600 including a hair removal surface 602 is provided, Figure 8 A schematic top view of the applicator head is provided, Figure 9 A schematic bottom perspective view of the applicator head is provided, Figure 10A schematic top perspective view of the applicator head is provided, and Figure 11 A schematic side view of the applicator head is provided. Figure 7 and Figure 8 , the applicator head perimeter 620 can surround the maximum extent of the applicator head 600 in a plane orthogonal to the alignment axis 700 (not shown). The applicator head perimeter 620 can be the smallest circle that completely surrounds the applicator head 600. The applicator head 620 can include one or more treatment sheets 604. The hair removal surface perimeter 630 is defined as the smallest circle that surrounds all treatment sheets 604. The hair removal surface 602 is the area on the applicator head 600 that is enclosed by the hair removal surface perimeter 630 and encloses one or more treatment sheets 604.

[0100] refer to Figure 9 、 Figure 10 and Figure 11 The hair removal surface 602 can provide for hair removal and, optionally, removal of oil, debris, or dead skin cells. The hair removal surface 602 can include a plurality of treatment sheets 604, each of which can include one or more cutting edges 606 surrounding and defining one or more openings 608. The cutting edges 606 can be closed, meaning each cutting edge 606 surrounds an opening 608 and is surrounded by the solid material comprising the treatment sheet 604. The cutting edges 606 can also be linear or non-linear, meaning that the cutting edges 606 can define any suitable shape, such as a circle, an oval, an ellipse, or an n-sided polygon, where n is 3 to 20 sides. The treatment sheet 604 can be comprised of any suitable material, including, but not limited to, metal. The non-linear cutting edges 606 can allow hair to be cut as it extends into the associated opening 608. Because the non-linear cutting edges 606 surround the opening 608, hair can be cut as the treatment sheet 604 passes over the hair in any direction, thereby enabling multi-directional hair cutting. Multi-directional hair cutting is particularly beneficial under the background of back hair removal, because the user of back hair removal device 100 may be difficult to move device 100 in a limited or consistent direction (for example, when touching device 100 to touch back above or below the shoulder). Small aperture 608 delivers a safe shave, because skin cannot protrude into the opening, which may cause cuts and incisions. The surface around aperture 608 of treatment sheet 604 also supports skin, thereby reducing protrusion and increasing safety. In other words, the size of aperture 608 can be designed to guarantee that skin can not protrude into the aperture to be cut by cutting edge 606. For the convenience of rinsing hair, oil and / or debris from aperture 608, cutting edge 606 and / or treatment sheet 604, applicator head 600 may comprise a plurality of applicator head apertures 618.

[0101] Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 、 Figure 16 、 Figure 17 、 Figure 18 and Figure 19 To illustrate various examples of applicator heads 600 including hair removal surfaces 602. Figure 14 Each of the figures other than 601 shows a hair removal surface 602 comprising a plurality of treatment sheets 604, Figure 14 A single treatment sheet 604 is shown. It should be understood that a variety of configurations of both the applicator head 600 and the hair removal surface 602 are within the scope of the present disclosure, and the variations shown are exemplary only. As shown, an applicator head perimeter 620 can surround each applicator head 600. Similarly, a hair removal surface perimeter 630 is the smallest circle that surrounds the hair removal surface 602 and lies in a plane orthogonal to the alignment axis 700. The maximum extent of the hair removal surface 602 is generally defined by the outermost edge of the one or more treatment sheets 604.

[0102] Figure 20 、 Figure 21 and Figure 22 Fitted to illustrate the multi-angle deflector 500. The multi-angle deflector 500 may have an open architecture that enables cut hair and other debris to be flushed away. Figure 20 is an example of a schematic side view of a multi-angle deflector 500 in the form of a wave spring 502. The wave spring 502 can include a plurality of leaf springs or formed washers that are stacked and interconnected. The plurality of leaf springs can have a deflection stiffness ranging from 0.05 N / mm to 5 N / mm. It should be understood that other configurations and various types of multi-angle deflectors 500 can be employed, including but not limited to those described below. The wave spring 502 includes a flushing window 552, a deflector-base connection portion 520, and a deflector-applicator connection portion 530. Figure 21 It shows that Figure 20 An example of a schematic top view of a multi-angle deflector 500 is shown. Figure 22 It shows that Figure 20 and Figure 21 An example of a schematic bottom view of the multi-angle deflector 500 is shown. The deflector perimeter 540 may surround the maximum extent of the multi-angle deflector 500 in a plane orthogonal to the alignment axis 700.

[0103] Still refer to Figure 20 、 Figure 21 and Figure 22 The multi-angle deflector 500 may include one or more central openings 550 similar to those in FIG. Figure 3The one or more central openings 408 of the base 402 are shown and optionally cooperate therewith. By allowing water to pass through the central opening 408 of the base 402 and enter the central opening 550 of the wave spring 502, cut hair and other debris can be rinsed. The water can then pass through the one or more applicator head openings 618, as shown. Figure 10 552.

[0104] The multi-angle deflector 500 enables the hair removal surface 602 to maintain contact with the skin on all areas of the body. This is useful when the user cannot see. The multi-angle deflector 500 also helps maintain contact between the hair removal surface 602 and the skin when moving over steeply contoured areas, such as around the shoulder blades. Because the hair removal surface 602 described herein provides multi-directional hair cutting, the user can move the hair removal device 100 in any direction without having to maintain a consistent stroke pattern or direction. The combination of the hair removal surface 602 and the multi-angle deflector 500 enables three-dimensional pivoting movement at all points of the hair removal surface 602, allowing the device to be used in any direction while maintaining good contact with the skin's contours. The multi-angle deflector 500 provides deflection in all planes, enabling controlled tilting motion and cushioning. This reduces the load on the cutting tip, providing a safer shave. Furthermore, the multi-angle deflector 500 allows the entire cutting edge 606 to be used for cutting hair, maximizing the efficiency and benefits of being able to cut in all directions. As previously discussed, the opening 608 with the cutting edge 606 in the one or more treatment sheets 604 allows the user to make strokes in any direction without worrying about the cutting edge 606 being perpendicular to the skin (e.g., to avoid slicing cuts). Especially when an applicator head 600 having such a hair removal surface 602 is used in conjunction with the multi-angle deflector 500, the user can freely move their arm in a non-linear stroke, just as they would when using a scrubber. Using a scrubbing motion; up, down, or sideways reduces the time and effort expended compared to a linear blade.

[0105] Figure 23is an example of a schematic diagram illustrating various relevant perimeters of a hair removal device 100 according to any of the various examples described herein. The hair removal device 100 may include a base 402 having a base surround perimeter 411. The hair removal device 100 may also include an applicator head 600 having an applicator head perimeter 620. The applicator head 600 may be coupled to the base 402 and may include a hair removal surface 602 having a hair removal surface perimeter 630. The hair removal device 100 may also include a multi-angle deflector 500 coupling the base 402 to the applicator head 600. The multi-angle deflector 500 may have a deflector perimeter 540.

[0106] The base surrounding perimeter 411 can be of any size, for example, in some configurations, the base surrounding perimeter can be 30 mm to 420 mm.

[0107] The deflector perimeter 540 may be of any size, for example in some configurations the deflector perimeter may be 30 mm to 420 mm.

[0108] The applicator head circumference 620 can be any size, for example, in some configurations, the applicator head circumference can be 30 mm to 420 mm.

[0109] The hair removal surface perimeter 630 can be any size, for example, in some configurations, the hair removal surface perimeter can be 30 mm to 420 mm.

[0110] According to various configurations, the deflector perimeter 540 can be greater than or equal to the applicator head perimeter 620. To provide non-limiting examples, the deflector perimeter 540 can be 0% to 200% greater than the applicator head perimeter 620 or equal to the applicator head perimeter.

[0111] According to various configurations, the applicator head perimeter 620 can be greater than or equal to the base surrounding perimeter 411. To provide non-limiting examples, the applicator head perimeter 620 can be 0% to 200% greater than the base surrounding perimeter 411 or equal to the base surrounding perimeter.

[0112] According to various configurations, the applicator head perimeter 620 can be greater than or equal to the hair removal surface perimeter 630. To provide a non-limiting example, the applicator head perimeter 620 can be 0% to 200% greater than the hair removal surface perimeter 630 or equal to the hair removal surface perimeter.

[0113] According to various configurations, the deflector perimeter 540 can be greater than or equal to the hair removal surface perimeter 630. To provide non-limiting examples, the deflector perimeter 540 can be 0% to 200% greater than the hair removal surface perimeter 630 or equal to the hair removal surface perimeter.

[0114] Because the perimeter of the multi-angle deflector 500 is similar or nearly close to the perimeter of the base 402, the applicator head 600 or hair removal surface 602 provides stability by ensuring that the deflection stiffness and compression are equal at all points around the perimeter of the hair removal surface 602 (which helps provide a hair removal device 100 that is stable and usable in all directions, rather than just linear travel).

[0115] Figure 24 is an example of a schematic top perspective view of the hair removal device 100. The hair removal device 100 may include a proximal portion 200, a midsection 300, and a distal portion 400 aligned along a longitudinal axis 702, including a handheld portion 103. The midsection 300 may be disposed between the proximal portion 200 and the distal portion 400. The proximal portion 200 may include a handle 202. The handle 202 may have an ergonomic shape that conforms to the user's hand. The handle 202 may include a grip 204 that includes texture to increase the coefficient of friction between the user's hand and the proximal portion 200 of the hair removal device 100, which may be particularly useful for hair removal devices 100 typically used in showers or other wet conditions. The handle 202 and grip 204 may comprise any suitable material or combination of materials, such as, for example, plastic, metal, or a combination thereof. Because the distal portion 400 may be detachable or separable from the midsection, the base 402 may also be a separate handheld portion 103. The middle portion 300 can be coupled to the proximal portion 200 and can include one or more segments, such as, for example, a first telescoping segment 302 and a second telescoping segment 304. The one or more segments can allow the middle portion 300 to be extendable, retractable, foldable, or compressible. The segments of the middle portion 300 can comprise any suitable material or combination of materials, such as, for example, plastic, metal, or a combination thereof. Furthermore, the distal portion 400 can be coupled to the middle portion 300. As will be discussed in greater detail, the distal portion 400 can include a base 402, a multi-angle deflector 500 coupled to the base 402, and an applicator head 600 coupled to the multi-angle deflector 500. The base 402, the multi-angle deflector 500, and the applicator head 600, as well as any subcomponents thereof, can comprise any suitable material or combination of materials, such as, for example, plastic, metal, or a combination thereof. As previously discussed, the multi-angle deflector 500 can be adapted to provide a multi-directional deflectable connection of the applicator head 600 relative to the base 402.

[0116] Increasing the length of the hair removal device 100 via a plurality of telescopic segments, for example, enables the user to reach all areas of their back. Changing the length of the hair removal device 100 enables the user to set the length of their expectation, thereby customizing the experience to their specific ergonomic requirements. Adjustable length also allows different lengths to be used for different areas of the back (for example, the length required for removing hair from the shoulders may be different from the length required for removing hair around the middle of the spine). In order to enable access to the most difficult areas such as the area along the spine, when fully extended, the combined length of the proximal portion and the middle portion along the longitudinal axis 702 can be between 1 cm and 75 cm. When fully collapsed, the combined length of the proximal portion and the middle portion along the longitudinal axis 702 can be between 0.5 cm and 70 cm, or can be 10 cm to 50 cm. Collapsible or foldable middle portion can also achieve more cautious storage and improved travel options.

[0117] Figure 25 is an example of a schematic bottom perspective view illustrating the distal portion 400 of the hair removal device 100. The distal portion 400 may include a base 402, a multi-angle deflector 500 coupled to the base 402, and an applicator head 600 coupled to the multi-angle deflector 500. The multi-angle deflector 500 may include a wave spring 502. The applicator head 600 may include or be coupled to a hair removal surface 602. Figure 25 Also shown is a base-handle connection portion 406 of the base 402. The base-handle connection portion 406 can provide a permanent or releasable connection between the base 402 and the intermediate portion 300. For example, the base-handle connection portion 406 can include male or female threads that engage corresponding threads on one of the segments 302, 304 of the intermediate portion 300, such as Figure 24 It will be appreciated that any type of connection may be employed including, but not limited to, a threaded connection or a friction connection.

[0118] Figure 26is an example of a schematic exploded side view illustrating the distal portion 400 of the hair removal device 100. The base 402, multi-angle deflector 500, and applicator head are aligned along an alignment axis 700. More specifically, the first portion 402a of the base 402 is aligned along the alignment axis, while the second portion 402b is not aligned along the alignment axis. The second portion 402b extends along the longitudinal axis 702 of the hair removal device 100, along which the intermediate portion 300 and the proximal portion 200 can be aligned and connected. A base longitudinal axis 703 can extend along the first portion 402a of the base. The base longitudinal axis 703 can be orthogonal to the alignment axis 700 and can be disposed at an angle 704 relative to the longitudinal axis 702. Angle 704 can be any suitable angle, such as, for example, 5 to 80 degrees, 10 to 70 degrees, 20 to 60 degrees, 30 to 50 degrees, or approximately 45 degrees, specifically enumerating all 0.5 degree increments therebetween. The first portion 402a of the base 402 can have a base thickness 414, the multi-angle deflector 500 can have a deflector thickness 518, and the applicator head 600 can have an applicator head thickness 616. In a relaxed, uncompressed state, the multi-angle deflector thickness 518 can be greater than the base thickness 414 and / or greater than the applicator head thickness 616. Depending on the configuration, the thickness 518 of the multi-angle deflector 500 can also be substantially similar to the base thickness and / or the applicator head thickness. Depending on the configuration, the thickness 518 of the multi-angle deflector 500 can be between 1 mm and 100 mm. The wave spring 502 can have a diameter 560 of 75 mm or approximately 10 mm to 150 mm, which can be substantially similar to or equal to the diameter 650 of the applicator head 600 to prevent the applicator head 600 from catching on sharp contours, which would otherwise cause a tipping or overturning effect (e.g., tilting).

[0119] Figure 27 、 Figure 28 and Figure 29 Fittingly, the distal portion 400 of the hair removal device 100 is shown including a base 402 . Figure 27 A schematic top perspective view is provided, Figure 28 A schematic side view is provided, and Figure 29 A schematic top view is provided.

[0120] Figure 30 、 Figure 31 、 Figure 32 、 Figure 33 、 Figure 34 、 Figure 35 、 Figure 36 、 Figure 37 、 Figure 38 、 Figure 39 、 Figure 40 and Figure 41Fitted to illustrate deflection and compression of the multi-angle deflector 500 . Figure 30 、 Figure 33 、 Figure 36 and Figure 39 A schematic side view of the distal portion 400 of the hair removal device 100 is provided in an uncompressed state, e.g., without a load applied to the applicator head 600 and / or base 402. When in the uncompressed state, the multi-angle deflector 500 can have an uncompressed thickness 640. The uncompressed thickness 640 can be 1 mm to 100 mm. Figure 31 、 Figure 34 、 Figure 37 and Figure 40 A schematic side view of the distal portion 400 of the hair removal device 402 is provided, compressed at a compression angle 644 relative to the alignment axis 700. The compression angle 644 can be between 0 and 60 degrees. Although the angle 644 is shown in a single plane, it should be understood that the multi-angle deflector 500 can deflect in any direction relative to the alignment axis 700. Under such uneven loading, a portion of the multi-angle deflector 500 can maintain an uncompressed thickness 640, while another portion of the multi-angle deflector 500 can be compressed to a compressed thickness 642. The compressed thickness 642 can maintain at least some separation between the applicator head 600 and the base 402, or the compressed thickness 642 can allow the applicator head 600 and the base 402 to contact, which can be referred to as a "zero" thickness.

[0121] Figure 32 、 Figure 35 、 Figure 38 and Figure 41 A schematic side view of the distal portion 400 of the hair removal device 402 compressed along the alignment axis 700 is provided. When compressed, the multi-angle deflector 500 can have a compressed thickness 642. The compressed thickness 642 can be 0 mm to 100 mm. Figure 30 、 Figure 31 and Figure 32 In the embodiment of the present invention, the multi-angle deflector is a wave spring 502. The wave spring 502 can comprise metal or a rigid material. The wave spring 502 can be produced by any suitable method, including, for example, additive manufacturing techniques such as 3D printing or by metal forming. Figure 33 、 Figure 34 and Figure 35 In the embodiment of the present invention, the multi-angle deflector is a sponge 508. The sponge 508 can be composed of natural or synthetic materials. Figure 36 、 Figure 37 and Figure 38 In the embodiment of the present invention, the multi-angle deflector is an elastomeric web 510. The elastomeric web 510 may comprise an elastomeric material. The elastomeric web 510 may be produced by any suitable method, including, for example, additive manufacturing techniques such as 3D printing. Figure 39 、 Figure 40 and Figure 41 , the multi-angle deflector is a deformable substrate 512. The deformable substrate 512 can comprise any material capable of providing the multi-angle compression and deflection described herein.

[0122] The multi-angle deflector 500 can have a compression load range that represents the resistance of the multi-angle deflector to compression from an uncompressed thickness 640 to a compressed thickness 642 when the alignment axis is parallel to the direction of gravity and the multi-angle deflector 500, with the applicator head 600 freely suspended. The compression deflection stiffness of the present invention can be measured on an Instron 5965 electromechanical test system or other test standards (such as, but not limited to, ASTM, ISO, or DIN). The compression load range, as measured when an upward force is applied at the center of the applicator head 600, can be between 0.05 N / mm and 5 N / mm. Similarly, the multi-angle deflector 500 can have a deflection stiffness that represents the resistance of the multi-angle deflector to deflection at an angle 644 when the alignment axis is parallel to the direction of gravity and the multi-angle deflector 500, with the applicator head 600 freely suspended. The deflection stiffness, as measured when an upward force is applied at the periphery of the applicator head 600, can be between 0.05 N / mm and 5 N / mm. The multi-angle deflector 500 can have a travel range defined as the difference between the uncompressed thickness 640 and the fully compressed thickness 642. The travel range can be in the range of 1 mm to 100 mm.

[0123] refer to Figure 31 、 Figure 34 、 Figure 37 and Figure 40Depending on the configuration, the multi-angle deflector 500 may be compressed due to one or more inconsistent forces F1 applied to the hair removal surface 602. The one or more inconsistent forces F1 may, for example, be applied unevenly or only to one edge of the applicator head 600. The inconsistent forces F1 may generate a pivoting or sawing force F2 on opposite sides of the applicator head 600. Depending on the configuration, this pivoting or sawing force F2 may be balanced or offset by an opposing force F3 from the multi-angle deflector 500, as the multi-angle deflector 500 may be coupled to the applicator head 600. Similar results can be achieved using multiple springs 504 or multiple cantilever springs 514, as described below. Thus, depending on the configuration, compression of the multi-angle deflector 500 in one area does not necessarily result in extension of the multi-angle deflector 500 in any other area, thereby preventing uncontrolled sawing motion of the hair removal surface 602. Even when subjected to force F1 in multiple directions, the multi-angle deflector 500, according to various configurations, does not allow the hair removal surface 602 to tilt away from the skin. For example, even if the hair removal surface 602 or the edge of the applicator head 600 gets stuck on the skin due to a high-friction area, or gets stuck on an extreme contour of the body, the hair removal surface 602 will not flip or tilt, which could lead to undesirable effects such as the lower edge of the applicator scraping the skin and reducing hair removal efficiency because the hair removal surface no longer contacts the skin. Avoiding uncontrolled sawing motion can lead to better contact between the hair removal surface and the skin, thereby ensuring better hair removal efficiency and maintaining the ability to shave in multiple directions. The leaf spring or wave spring allows the applied force F1 to be evenly distributed around the periphery of the hair removal surface. This ensures that the multi-directional movement of the hair removal surface is smooth and thus avoids any sudden movement of the blade relative to the skin, which could cause lacerations and cuts.

[0124] Figure 42 、 Figure 43 、 Figure 44 、 Figure 45 and Figure 46 Attached herewith are shown a multi-angle deflector 500 including a plurality of springs 504 and a deflector perimeter 540 defined relative to the plurality of springs 504 . Figure 42 and Figure 43 A schematic bottom perspective view of a hair removal device 100 including a multi-angle deflector 500 comprising a plurality of springs 504 is provided. Figure 44 Provided Figure 42 A schematic side view of the hair removal device 100 is shown.

[0125] refer to Figure 42 and Figure 43, the hair removal device 100 includes an applicator head 600, a multi-angle deflector 500, a base 402, and a handle 202 aligned along an alignment axis. The multi-angle deflector 500 may include a ball-and-socket pivot 570. The applicator head 602 may include a screw or other opening 672 that aligns with and mates with a threaded portion 572 of the ball-and-socket pivot 570. The ball-and-socket pivot 570 may allow the applicator head 600 to pivot in any direction while remaining attached to the multi-angle deflector. A plurality of springs 504 may be disposed about the ball-and-socket pivot 570 to bias the applicator head 600 to a neutral position that is generally parallel to the multi-angle deflector 500 and in a plane orthogonal to the alignment axis 700.

The middle portion 300 includes only a single segment 305. The proximal portion 200 includes a handle 202 having a knob shape. It should be understood that any version of the hair removal device 100 described herein can employ a similar configuration for the proximal portion 200, the middle portion 300, and the distal portion 400. Similarly, it should be understood that the multi-angle deflector 500, including multiple springs 504, can be used in any configuration of the hair removal device 100 described herein.

[0128] Figure 47 FIG. 1 is a schematic perspective view of a hair removal device 100 including a multi-angle deflector 500 comprising a plurality of springs 504, showing an applicator head 600 in a deflected state. Figure 47 As shown, inconsistent compression of the multi-angle deflector 500 in one area does not result in extension of the multi-angle deflector in any other area, thereby avoiding uncontrolled sawing motion of the hair removal surface 602. The inconsistent force F1 can generate a pivoting or sawing force F2 on opposite sides of the applicator head 600. According to various configurations, this pivoting or sawing force F2 can be balanced or offset by an opposing force F3 from the multi-angle deflector 500, as the multi-angle deflector 500 can be coupled to the applicator head 600 via one or more of the plurality of springs 504.

Figure 48 A schematic bottom perspective view of the hair removal device 100 is provided, and Figure 49 A schematic side view of the hair removal device is provided, which includes a multi-angle deflector 500 having multiple deflection arms 506. Figure 48 The multi-angle deflector 500 may include a ball-and-socket pivot 570. The applicator head 602 may include a screw opening 672 that aligns with and mates with a threaded portion 572 of the ball-and-socket pivot 570. The ball-and-socket pivot 570 may allow the applicator head 600 to pivot in any direction while remaining attached to the multi-angle deflector. A plurality of deflection arms 506 may be disposed about the ball-and-socket pivot 570 and optionally attached thereto. The deflection arms 506 may bias the applicator head 600 to a neutral position that is generally parallel to the multi-angle deflector 500 and in a plane orthogonal to the alignment axis 700.

[0130] See also Figure 49 , the hair removal device 100 can include a proximal portion 200, a middle portion 300, and a distal portion 400 aligned along an alignment axis 700, along which the applicator head 600, the multi-angle deflector 500, and the base 402 are aligned. The middle portion 300 includes only a single segment 305. The proximal portion 200 includes a handle 202 having a knob shape. It should be understood that any version of the hair removal device 100 described herein can employ a similar configuration for the proximal portion 200, the middle portion 300, and the distal portion 400. Similarly, it should be understood that the multi-angle deflector 500, including multiple deflection arms 506, can be used in any configuration of the hair removal device 100 described herein.

[0131] Figure 50 A schematic bottom view of a multi-angle deflector 500 having a plurality of deflection arms 506 is provided. The deflector perimeter 540 of the multi-angle deflector 500 including the plurality of deflection arms 506 may surround the maximum extent of the plurality of deflection arms 506 in a plane orthogonal to the alignment axis 700.

[0132] Figure 51FIG2 is a schematic side view of a hair removal device 100 including a multi-angle deflector 500 comprising a plurality of deflection arms 506, with an applicator head 600 shown in a deflected state. An inconsistent force F1 can generate a pivoting or sawing force F2 on opposite sides of the applicator head 600. Unlike other configurations in which this pivoting or sawing force F2 is balanced or offset by an opposing force F3 from the multi-angle deflector 500, the multi-angle deflector 500 is not coupled to the applicator head 600 via one or more of the plurality of deflection arms 506. Instead, the stiffness of the deflection arms 506 can be calibrated to ensure that all deflection arms 506 remain in contact with the applicator head 600 even under an inconsistent force F1 that deflects the applicator head 600 to its maximum extent. Consequently, inconsistent compression of the multi-angle deflector 500 in one area does not result in extension of the multi-angle deflector in any other area, thereby preventing uncontrolled sawing motion of the hair removal surface 602.

[0133] Figure 52 The situation to be avoided is illustrated in FIG, which is a schematic side view of a hair removal device 100 including a multi-angle deflector 500 comprising a plurality of deflection arms 506, showing an applicator head 600 in a deflected state during uncontrolled sawing. Uneven forces F1 deflect the applicator head 600, generating pivoting or sawing forces F2 on opposite sides of the applicator head 600. Because the stiffness of the deflection arms 506 is not correctly calibrated, at least one of the deflection arms 506 loses contact with the applicator head 600, thereby forming a gap 580. This is an undesirable configuration that can result in an uncontrolled sawing effect, which can cause lacerations and cuts as previously described.

[0134] Figure 53 、 Figure 54 and Figure 55 Attached herewith is shown a multi-angle deflector 500 including a plurality of cantilever springs 514 and a deflector perimeter 540 defined relative to the plurality of cantilever springs 514 .

The applicator head 602 may include a screw aperture 672 that aligns with and mates with a threaded portion 572 of the ball-and-socket pivot 570. The ball-and-socket pivot 570 may allow the applicator head 600 to pivot in any direction while remaining attached to the multi-angle deflector. The plurality of cantilever springs 514 may be disposed about the ball-and-socket pivot 570 to bias the applicator head 600 to a neutral position that is generally parallel to the multi-angle deflector 500 and in a plane orthogonal to the alignment axis 700.

The deflector perimeter 540 of the multi-angle deflector 500 including the plurality of cantilever springs 514 can surround the maximum extent of the plurality of cantilever springs 514 in a plane orthogonal to the alignment axis 700. As in other similar configurations, the non-uniform force F1 can generate a pivoting or sawing force F2 at opposite sides of the applicator head 600, which can be balanced or counteracted by an opposing force F3 from the multi-angle deflector 500 because the multi-angle deflector 500 can be coupled to the applicator head 600 via one or more of the cantilever springs 514.

[0136] See also Figure 56, the hair removal device 100 can include a proximal portion 200, a middle portion 300, and a distal portion 400 aligned along an alignment axis 700, along which the applicator head 600, the multi-angle deflector 500, and the base 402 are aligned.
