DETAILED DESCRIPTION
[0030] As used in this disclosure and the appended claims, the singular forms “a”, “an”, and “the” include plural referents unless the content clearly dictates otherwise. As used in this disclosure and the appended claims, the term “or” is generally employed in its sense including “and/or” unless the content clearly dictates otherwise.
[0031] The following detailed description should be read with reference to the drawings. The detailed description and the drawings, which are not necessarily to scale, depict illustrative aspects and are not intended to limit the scope of the disclosure. The illustrative aspects depicted are intended only as exemplary.
[0032]
[0033] The handle assembly 20 comprises a handle 40. The handle 40 includes a connection portion 42 for supporting e.g. a hair removal head, such as a shaver head, for example a razor cartridge 44.
[0034] The handle assembly 20 comprises at least a first accessory component 100A. For example, as seen in
[0035] At least one of the accessory components may be assemblable to the handle 40. For example, as seen in
[0036] Additionally or alternatively, when multiple accessory components are present, two or more of the accessory components may be structurally analogous to one another, except as necessary for possible cooperation with one another. For example, as seen in
[0037] The coupling of multiple accessory components to one another may occur when and/or as at least two of them are assembled to the handle 40. For example, in
[0038] Additionally, the hair removal device may be provided as a kit comprising a handle, a head, and a plurality of accessory components. That accessory components may have different features that may be used by the user according to his/her desire.
[0039] The handle 40 includes an elongated grip portion 50 extending from the connection portion 42. The handle of the handle assembly as disclosed herein may be suitable for manipulation of the hair removal device, even when the handle is not connected to any accessory component. As such, the handle assembly as disclosed herein may offer a wide range of customization options.
[0040] The length of the grip portion 50, in the absence of any accessory component assembled thereto, may be sufficient for safe manipulation by a human hand, and may be sufficient for the hand to close there around.
[0041] The grip portion 50 may, for example, have a length of 80-150 mm. The length may be measured along a length axis L running between the connection portion 42 of the handle 40 and a free extremity 51 of the grip portion 50, located opposite the connection portion 42. The grip portion may have a width (as measured perpendicular to the length) of 6-25 mm.
[0042] At least one accessory component may be arranged laterally with respect to the handle 40 or grip portion 50 thereof. For example, as seen in
[0043] Additionally or alternatively, at least one accessory component may be arranged to extend beyond the free extremity 51 of the grip portion 50. For example, as seen in
[0044] At least one of accessory component may be disassemblable from the handle. For example, in
[0045] When multiple accessory components are present, at least two of them may be disassemblable from the handle. For example, in
[0046] In examples, when multiple accessory components are coupleable to one another, they may be decoupleable from one another when and/or as at least one of them is disassembled from the handle. For example, in
[0047] The handle assembly comprises a holding mechanism, of which a first portion is engageable with a second portion to resist disassembly of at least one accessory component from the handle or grip portion thereof. For example, in
[0048] When multiple accessory components are present, a first of the multiple accessory components may be provided with a first portion of a first holding mechanism, corresponding to a second portion of the first holding mechanism provided on the handle and engageable therewith, and a second of the multiple accessory components may be provided with a first portion of a second holding mechanism, corresponding to a second portion of the second holding mechanism provided on the handle and engageable therewith. For example, in
[0049] Additionally or alternatively, when multiple accessory components are coupleable to one another, the holding mechanism may be provided so as to resist decoupling of the accessory components from one another. For example, in
[0050] When multiple accessory components are each assembled to the handle and coupled to each other, resistance of decoupling of the accessory components from each other may serve to resist disassembly of at least one of the accessory components from the handle. For example, as seen in
[0051] As a nonlimiting example, at least one first portion of the holding mechanism may comprise one or more female features, and the corresponding second portion(s) of the holding mechanism may comprise a corresponding number of male features, or vice versa. For example, in
[0052] In
[0053] The use of one or more corresponding projections and indentations is not limited to being provided as a way of resisting decoupling of the accessory components from one another. Rather, it is foreseen as a variant to use these structures as an alternative to or in combination with the corresponding ridge(s) and groove(s), and/or as an alternative to or in combination with the corresponding recess(es) and protuberance(s) to resist disassembly of at least one accessory component from the grip portion. Likewise, the corresponding groove(s) and ridge(s), and/or the corresponding recess(es) and protuberance(s) may be used as an alternative to or in combination with the corresponding projections(s) and indentation(s) to resist decoupling of the accessory components from one another. Moreover, although the corresponding groove(s) and ridge(s) are shown in
[0054] The holding mechanism may include a press fit and/or a snap fit that is engageable to resist disassembly of at least one accessory component from the grip portion. For example, as seen in
[0055] The holding mechanism comprises two or more magnetic elements, of which a first magnetic element may comprise a first magnet, and of which a second magnetic element is positioned relative to the first magnetic element when the holding mechanism is engaged so that the first and second magnetic elements cooperatively resist disassembly of at least one accessory component from the handle or grip portion thereof. As a nonlimiting example, the first magnetic element may be provided in the first portion of the holding mechanism, and the second magnetic element may be provided in the second portion of the holding mechanism engageable therewith, or vice versa.
[0056] For example, as seen in
[0057] As explained earlier, when multiple accessory components are coupled to one another, a holding mechanism that is engageable to resist decoupling of the accessory components from one another can also have the effect of preventing disassembly of at least one of the accessory components from the handle. As seen in
[0058] The holding mechanism may comprise magnetic elements independently of whether it comprises male and female parts, or as seen in
[0059] According to examples, the second magnetic element may comprise a second magnet. In examples, the second magnetic element may simply comprise a magnetic material, such as iron, steel, cobalt etc. or any other Ferromagnetic materials, which, in 1s response to an applied magnetic field having a first polarity, is able to produce a magnetic field of an opposite polarity to the first polarity.
[0060] According to examples, at least one accessory may be made of a magnetic material. For example, the first accessory component (or the second accessory component, when present) may be made of a magnetic material. In this regard, the accessory component may be considered to be or comprise the second magnetic element.
[0061] The first and second magnetic elements may resist disassembly, be it disassembly of the first accessory component (or second accessory component, when present) from the handle or grip portion thereof, or by resisting decoupling of the first and second accessory components from one another, through magnetic attraction, or magnetic repulsion. For example, magnetic repulsion may be suitable for resisting disassembly when disassembly causes the first and second magnetic elements to pass by one another, whereas magnetic attraction may be suitable for resisting disassembly when disassembly does not cause the first and second magnetic elements to pass by one another.
[0062] For example, in the holding mechanism shown in
[0063] In order to resist disassembly through magnetic repulsion when the holding mechanism is engaged, the first magnetic element 11A may be positioned at the free extremity of the projection 182A such that the magnetic field it produces extends towards a fixed extremity of the projection 182A with a first polarity, and the second magnetic element 22B (which in this configuration comprises the second magnet) may be positioned at an open extremity of the corresponding indentation 183B and arranged to produce a field having a same polarity as the first polarity extending towards the closed extremity. When the free extremity of the projection 182A is intermediate the open and closed extremities of the indentation 183B, the magnetic fields of the first 11A and second 22B magnetic elements repel one another, and thus may resist decoupling.
[0064] At least one accessory component may have a higher overall mass and/or a higher overall density than the handle, and/or it may have a higher overall mass and/or a higher overall density than grip portion. For example, as seen in
[0065] For example, the grip portion 50 may comprise one or more of the following materials: M-ABS, MBS, Polycarbonate, PET, Copolyester, Polypropylene (including reinforced polypropylene), ABS, HIPS, PC/ABS, PC/PET, Polyacetal, PPE/PS, PLA compound, Polystyrene (GPPS), Polyethylene, Polyamide, Pre-Post-consumer recycled plastic, which may be well-suited for molding. Additionally or alternatively, the grip portion may comprise thermoplastic filaments (e.g. ABS, PLA, nylon, PETG), thermoplastic powders (e.g. polyamide 12, polyamide 11), thermoset photopolymer resins (e.g. standard, ABS-like, PP-like, rubber-like, high temperature) or thermoset liquid resins (e.g. standard, ABS-like, PP-like, rubber-like, high temperature), which may be well-suited for additive manufacturing processes. For example, the first accessory component may comprise any of the materials listed with regards to the grip portion, or, for example one or more of the following materials: M-ABS, MBS, polycarbonate, PET, copolyester, polypropylene, ABS, HIPS, PC/ABS, PC/PET, polyacetal, PPE/PS, thermoplastic filaments (e.g. ABS, Nylon), thermoplastic powders (e.g. polyamide 12, polyamide 11), thermoset photopolymer resins (e.g. ABS-like, PP-like), or thermoset liquid resins (e.g. ABS-like, PP-like). The first accessory component 100A may additionally or alternatively comprise a metal (e.g. Zamak, Aluminum), which may be well-suited for molding or Titanium, Stainless Steel, Cobalt chrome or Nickel which may be well-suited for additive manufacturing processes. For example, as explained earlier, it is foreseen for at least a portion of the first accessory component to comprise a magnetic element, which may include a metal material. The second accessory component 100B (when present) may be made of the same material(s) as the first accessory component 100A, or of different materials from the first accessory component 100A.
[0066] At least one accessory component may comprise an outer surface that is contactable by an appendage of a user when the accessory component is assembled to the grip portion. For example, the outer surface may be contactable by a user's hand. In
[0067] The outer surface may provide one or more ergonomic features to the handle assembly. For example, the outer surface may provide at least one of the following: gripping feature, a protrusion for engaging a concave region of the appendage (for example a palm of the user's hand), and a depression for receiving at least a portion the appendage (for example a finger of the user's hand). A gripping feature 122A, 122B is represented in
[0068] The gripping feature may provide a higher coefficient of friction against a user's skin than the remainder of the outer surface. This coefficient of friction may be provided, for example, through the use of a textured surface and/or a material such as a rubber. For example, the rubber may be an elastomeric or a thermoplastic elastomeric (TPE) material. The rubber may have a hardness of approximately 15-70 Shore A. The gripping feature may include, but are not limited to silicones, natural rubber, butyl rubber, styrene butadiene rubber, polyolefin-based TPEs, styrene butadiene styrene (SBS) TPEs, styrene ethylene butadiene styrene (SEBS) TPEs, polyamide TPEs (such as Pebax), polyester TPEs, or polyurethane TPEs. The gripping feature may indude a blend of one or more of these TPEs with other substances. The gripping feature may include a blend of multiple of these TPEs, possibly in combination other substances.
[0069] According to examples of the present disclosure, the gripping feature may be provided in combination with at least one other ergonomic feature. For example, in
[0070] As seen
[0071] Use of an insert 119A, 1196 to provide the ergonomic feature(s) may enhance recyclability, such as by allowing items materials which cannot be converted back into raw materials through a common process, (as with metal and plastic, for example) to be separated and processed independently from one another.
[0072] According to examples, the grip portion 50 may include a through-hole. Use of a through hole may offer weight and/or material reductions in the grip portion. As seen in
[0073]
[0074] As with the accessory components 100A, 1006 shown in
[0075] As seen in
[0076] At least one gripping feature 122A may be provided in a handle assembly 220 as shown in
[0077] In
[0078] Although, as seen in
[0079] In
[0080] At least one portion of the holding mechanism may be provided on a post extending from one of the accessory components towards another of the accessory components coupleable therewith. For example, as seen in
[0081] As a nonlimiting example, as seen in
[0082] As seen in
[0083] The first portion 480A of the holding mechanism may comprise a bulb 482A, and the second portion 480B of the holding mechanism may comprise a corresponding socket 483B into which the bulb 482A is snap-fittable. As seen in
[0084] Although
[0085] At least one of the accessory components may be provided as a plurality of bodies. For example, in
[0086] As seen in
[0087] The holding portion of the mechanism provided on a given accessory component may be arranged on each of these bodies. For example, in
[0088] As seen in
[0089] Although
[0090] As seen in
[0091] Although
[0092] As seen in
[0093] As seen in
[0094] Although
[0095]
[0096] As seen in
[0097] For example, at least one of the first and second magnetic elements may be provided at a free extremity of a post extending from the first accessory component towards the second accessory component. As seen in
[0098] As seen in
[0099] However, it is also foreseen that at least one first magnetic element 11A be made to magnetically engage a corresponding second magnetic element 22B without contacting it directly. For example, the post(s) may be arranged between the first 11A and second 22B magnetic elements.
[0100] Moreover, it is also foreseen that at least one first magnetic element 11A be made to magnetically engage a corresponding second magnetic element 22B without direct contact between the first 600A and second 600B accessory components. For example, the length(s) of the post(s) 790A, 790B, 792A, 792B, 794A, 7948 may be insufficient for contact between the first 600A and second 600B accessory components, or the post(s) may even be absent.
[0101] When an accessory component comprises multiple bodies, the portion of the holding mechanism provided on the accessory body may be provided on each of these bodies.
[0102] For example, a magnetic element may be provided on each of the bodies 610A, 660A of the first accessory component 600A, and these magnetic elements may be magnetically engageable with one or more magnetic elements provided on the second accessory component 600B.
[0103] As seen in
[0104] According to an example, and independently of the manner in which the first bodies 610A, 610B couple to one another, the second bodies 660A, 660B of the first 600A and second 600B accessory components may be provided with a pair of magnetic elements 11A, 22B, in a similar manner to that which is described above with regard to the first bodies 610A, 610B.
[0105] As seen in
[0106]
[0107] As seen in
[0108] The weighted element 5 may be removably attached to the accessory component, which may allow a user to reposition the weighted element 5 with respect to the remainder of the handle assembly 820. For example, in
[0109] Although not shown in the figures, the holding mechanism may comprise a mixture of pairs of bulbs and sockets, rods and cavities, and first and second magnetic elements.
[0110] Although the figures show pairs of accessory components, it is also foreseen to provide an odd number of accessory components. Moreover, although these figures show multiple accessory components as cooperating with one another (such as by coupling to each other), it is also foreseen to provide at least one accessory component which does not couple to another accessory component. In the examples shown, the accessory components are provided to the side portions of the grip portion, that is, those portions of the grip portion that are directed to the left or to the right of a hand holding the grip portion in a normal orientation of use. Additionally or alternatively, an accessory component may be attached to a back portion of the grip portion, for example to provide a longer handle length to the handle assembly (not shown). The back portion is a portion of the grip portion that is directed to the palm of a hand holding the grip portion in the normal orientation of use. Such accessory components providing a longer handle length may extend beyond the upper end and/or beyond the lower end of the grip portion, the upper end being the one provided with the connection portion 42 or 242.
[0111] A handle assembly as disclosed herein may be recycled with ease, owing to the accessory component/components being separable from the handle.
[0112] A handle assembly as disclosed herein may be recycled, for example, by disassembling the at least one accessory component from the handle or grip portion thereof. The accessory component may subsequently be recycled according to techniques suitable for the accessory component's constituent materials. As a nonlimiting example, one or more metal recycling techniques, for example one or more ferrous metal recycling technique may be used in recycling the accessory component.
[0113] Additionally or alternatively, the handle or grip portion thereof may be recycled, subsequent to disassembly of the accessory component (or components) therefrom, according to techniques suitable for the handle's or grip portion's constituent materials. For example, one or more plastic recycling techniques may be used. For example, when the handle or grip portion is made of ABS, a plastic pyrolysis technique may be used to convert the ABS into fuel oil.
[0114] Moreover, unlike known multi-piece handle assemblies, the handle assembly as disclosed herein allows a user to replace one or more items of the handle assembly while conserving the remainder thereof for reuse with replacement items. For example, a user may desire to replace an old handle with a new handle, and to conserve the accessory component/components for reuse with the new handle. Additionally or alternatively, for example, a user may desire to replace one or more old accessory components with one or more new accessory components, and to conserve the handle for reuse with the new accessory component/components.
