, Description:TECHNICAL FIELD
Present disclosure generally relates to the field of horology. Particularly, but not exclusively, the disclosure relates to a timepiece. Further, embodiments of the present disclosure relate to a casing assembly for a timepiece.

BACKGROUND OF THE DISCLOSURE
Conventionally, timepieces may be employed with a casing having a dial, or in general, a display element that is capable of indicating time. Such dials of the timepiece may have an analog configuration, a digital configuration, or a combination of both. The dial may be positioned in the casing such that, other components or mechanism of the timepiece including, but not limited to, a movement, a movement holder, a stem, and the like, may be concealed from visibility. Also, such concealment by the dial may be necessary to avoid interference of such components from viewability and visibility of hands of the timepiece being connected to movement from showcasing time.

Conventionally, such concealment is preformed by assembling the components of the timepiece in a defined order, where the casing may be defined with a through opening for assembling of the components therein. One end of the casing may be configured to receive a glass, while an other end of the through opening, opposite to one end, may be configured to receive the components of the timepiece for assembling. The casing of the timepiece may be positioned with the glass side on a platform so that, the components of the timepiece may be assembled from the other end. Additionally, the other end of the through opening may be covered by a back plate, which may be held by means of fasteners while the components of the timepiece are hermitically sealed within the casing.

With advent of technology, assembling of the components of the timepiece have been performed by suitably connecting and disconnecting the back plate with the casing, where such connection therebetween may be performed by defining an internal thread or snap-fitting means within the casing and/or the back plate. With such configuration, aesthetical appeal of the timepiece may be enhanced and also provide comfort for wearing such timepiece in view of elimination of the fasteners.

In view of above-mentioned conventional timepieces, components of the timepiece such as glass may be prone to damages such as, but not limited to, scratches, fingerprint smudge, discoloring, wear-off, and the like, during assembly or servicing process. Such damages to the glass may cause blurred appearance of the dial and/or hands of the timepiece, which may hinder the user for observing time in the timepiece. Additionally, assembling in such conventional process may require skilled person or skilled apparatus for assembly and disassembly of the components of the timepiece. In addition, the back plate may also add to the thickness of the timepiece, which may render the timepiece bulky and heavy based on which coefficient of aesthetic appeal of the timepiece may be reduced. Also due to such requirements for assembly and high number of components of the timepiece, cost associated with manufacturing, processing, assembling and/or servicing of the timepiece may inherently increase, thereby increasing overall costs incurred for production of such timepiece.

The present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the prior arts.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgment or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

In the following detailed description of the embodiments of the disclosure, reference is made to the accompanying figures that form a part hereof, and in which the timepiece are shown by way of illustrating specific embodiments of the present disclosure may be practiced. These embodiments are described with sufficient details to enable those skilled in the art to practice the disclosure, and it is to be understood that other embodiments may be utilized and that changes may be made without departing from the scope of the present disclosure.

Reference will now be made to the exemplary embodiments of the disclosure, as illustrated in the accompanying drawings. Wherever possible, same numerals have been used to refer to the same or like parts. The following paragraphs describe the present disclosure with reference to Fig. 1-3b.

Figure 1 is an exemplary embodiment of the present disclosure which is a sectional view of a casing assembly (100) of a timepiece (200). The casing assembly (100) may be adapted to be coupled with a connecting means [not shown in Figures] including but not limited to, a strap, a belt, a chain, a fastener, and any other connecting means that may be capable of securing the casing assembly (100) to display time. Based on nature of the connecting means for the casing assembly (100), the timepiece (200) may be defined to be at least one of a wristwatch, a wall clock, a table clock, a pocket (13) clock and any other horological configuration of the timepiece (200). In an exemplary embodiment, the casing assembly (100) illustrated in Fig. 1 is of a wristwatch, while configuration of the casing assembly (100) as described herein may also extend to other horological configurations of the timepieces with selective modifications without deviating from features described herein.
Referring again to Fig. 1, the casing assembly (100) of the timepiece (200), among other components, includes a case body (1), a movement (6), a dial (7), a crown (14), a stem (15) and sealing members, that may be adaptably cascaded within the casing assembly (100) by a bezel (8) and a glass (9), for suitably displaying time. The casing assembly (100) may also include indicators such as, but not limited to, a plurality of hands or projections [not shown in Figures] that may be selectively coupled to the movement (6) and positioned above the dial (7) of the casing assembly (100) to indicate time, date, day and the like.
The case body (1), as illustrated in Fig. 1, may be integrally formed to include a back cover portion (2) for defining a cavity to receive components of the casing assembly (100). The case body (1) with the back cover portion (2) may be formed as an integral components or the back cover portion (2) may be permanently joined with the case body (1) by processes including, but not limited to, welding, brazing, and the like, to resemble an integral component. The back cover portion (2) of the case body (1) may include an inner surface and an outer surface. The case body (1) with the back cover portion (2) may be made from material including, but not limited to, steel, while other materials such as but not limited to, brass, carbon fiber, and the like may also be employed for manufacturing. The inner surface of the back cover portion (2) may be capable of accommodating the components of the casing assembly (100), while the outer surface of the back cover portion (2) may be adapted to define a resting region on which the casing assembly (100), and in-turn the timepiece (200) may rest on a defined surface. With such configuration of the case body (1) and the casing assembly (100), the components of the timepiece (200) may be obviated from exposure to the surroundings at the outer surface of the case body (1).
In an embodiment, the case body (1) may be defined with a plurality of step portions for receiving and selectively positioning the components of the casing assembly (100), and in-turn of the timepiece (200). The plurality of step portions may be adapted to abut by at least some of the components of the timepiece (200) for securing and/or positioning within the case body (1) of the casing assembly (100). The plurality of step portions may be defined at least from the inner surface of the back cover portion (2) and along periphery of the case body (1), based on a number of factors affecting configuration of the casing assembly (100). In an embodiment, such factors may be including, but not limited to, number of components of the casing assembly (100), thickness of each of the components, interlocking between each of the components, number of sealing members required for hermitically seal the casing assembly (100) and in between the components of the casing assembly (100), and any other factor affecting position and operation of the components of the casing assembly (100). The plurality of step portions may be either formed in the case body (1) or may be externally coupled to seat within the case body (1).
In the illustrative embodiment, the case body (1) includes three step portions, namely a first step portion (3), a second step portion (4), and a third step portion (5), which ascend from the inner surface of the back cover portion (2) till a brim portion of the case body (1) that may be exposed to the surroundings when the casing assembly (100) is in disassembled state. The first step portion (3), the second step portion (4) and the third step portion (5) are integrally formed in the case body (1) such that, each step portion concentrically extends from an inner portion of the case body (1). The first step portion (3) may be configured to receive and position the movement (6) of the timepiece (200). The movement (6) of the timepiece (200) may be adaptably secured in the movement holder (23) and then seated within thickness of the first step portion (3) for accommodating in the case body (1). Further, the second step portion (4) may be configured to receive and accommodate the dial (7) relative to the movement (6), where at least some portion of the dial (7) may be supported by the second step portion (4) while remaining portion of the dial (7) may be accommodated on the movement (6). Additionally, the third step portion (5) of the case body (1) may be configured to define the rim portion of the case body (1), which may be adapted to receive and position the bezel (8). The bezel (8) may be configured to support as a side and/or top protective element for the case body (1), along with providing support to the glass (9) for covering the casing assembly (100). The bezel (8) may be connectable to the case body (1) by means including, but not limited to, adhesive bonding, seal fitment, snap fitting, thread fitting and any other means for temporary and detachable connection between the bezel (8) and the case body (1) of the casing assembly (100). Additionally, the bezel (8) may be defined with a ridge (12) on a surface which interfaces with the case body (1) for coupling. The ridge (12) may be configured to receive a first sealing member (11), to hermitically seal the interface between the case body (1) and the bezel (8). In an illustrative embodiment, the first sealing member (11) may be at least one of O-ring, a sealing ring, a diaphragm, and any other elastically and/or plastically deformable material that may selectively deform and allow accommodation of the bezel (8) on the cover body with ingress protection. Also, the ridge (12) may be configured to allow the case body (1) and the bezel (8) to snap-fit and seal to form the casing assembly (100).

Referring now to Fig. 2, the bezel (8) may be configured to receive and accommodate the glass (9) above the case body (1), where such glass may be made of mineral glass, quartz glass, silicone and any other transparent or substantially transparent material. The bezel (8) may be defined with a fourth step portion (10) [as per nomenclature, first three step portions pertains to that of the case body (1)] horizontally extending towards center of the casing body, where such extension of the fourth step portion (10) may adaptably act as a platform for receiving the glass (9). The glass (9) may be coupled to the bezel (8) by means including, but not, limited to adhesive bonding to secure the glass (9) onto the bezel (8). In the illustrative embodiment, the glass (9) is coupled to the bezel (8) via a second sealing member (21), where the second sealing member (22) is configured to snugly fit the glass (9) on the bezel (8) to hermitically seal the casing assembly (100) on connecting with the case body (1). The second sealing member (21) may be at least one of O-ring, a sealing ring, a diaphragm, or any other elastically and/or plastically deformable material or any adhesive material such as, but not limited to, epoxy, organic binders, inorganic binders, and the like, that may provide ingress protection. With such configuration, the glass (9) is positioned to substantially flush with the bezel (8), where such flush between the glass (9) and the external surface of the bezel (8) may define thickness of the casing assembly (100). It can be noted that the term “substantially” indicates that the thickness of the timepiece (200) including the glass (9) in the bezel (8) to excluding the glass (9) from the bezel (8) may be negligible or in a dimension ranging utmost to 0.9mm, which is negligible compared to thickness of the timepiece (200). Due to such configuration of the casing assembly (100), thickness of the timepiece (200) may be minimized whereby providing an aesthetical appeal to the timepiece (200). The thickness of the timepiece (200) may be in a range of about 4.2mm to about 4.4mm, where the casing assembly (100) and in-turn the glass (9) may be accommodated within such thickness of the timepiece (200).

Referring to Figs. 1, 2 and 3a, the dial (7) may be accommodated on the second step portion (4) of the cover body (1) such that, a portion of the dial (7) may be sandwiched and peripherally accommodated between the cover body (1) and the bezel (8). In the illustrative embodiment, the dial (7) is split to a plurality of components including, but not limited to, a base dial (16) and a dial ring (17), where the dial ring (17) may be detachably disposed on the base dial (16). The base dial (16) is connectable to the movement (6) and is accommodated on the second step portion (4) of the case body (1). Further, at least a portion of the base dial (16) and the dial ring (17) may be detachably interlocked by a complementary profile on one another, where such complementary profile may be including, but not limited to, a zig-zag profile, a sinusoidal profile, and any other profile which may restrict rotational movement (6) of the dial ring (17) about the base dial (16) while allowing movement (6) in a vertical direction of the casing assembly (100). Additionally, such complementary profile of the dial ring (17) may be configured to enclose a portion of the base dial (16).

As seen in Figs. 2 and 3a, the dial ring (17) is defined with a locking member (19), while the base dial (16) is defined with a slit (18) to complementarily engage with the locking member (19) defined in the dial ring (17). The locking member (19) may be configured to radially extend from periphery of the dial ring (17) and seat within the slit (18) of the base dial (16), to obviate independent rotation of the dial ring (17) about the base dial (16) on engagement. Further, the base dial (16) may be defined with a provision (22) at interface underneath the slit (18) and the locking member (19), where such provision (22) may be defined in at least a portion of the base dial (16) such that an access may be provided to the movement (6) through the base dial (16) and in-turn the dial (7). In an embodiment, a tool may be insertable through the provision (22) for accessing the movement (6), where such tool may be including, but not limited to, a key element, a screwdriver, a power tool, an Allen key and any other tool that may be capable of being inserted via the provision (22) to access the movement (6). Further, the provision (22) in the base dial (16), and in-turn the dial (7), may be visible and/or accessible on sequentially disassembling the bezel (8) with the glass (9), and the dial ring (17) having the locking element. Such configuration may allow accessing of the movement (6) without having to remove the base dial (16). That way, design, and aesthetic appeal of the base dial (16) and the dial ring (17) may be maintained without having to indicate presence of the provision (22) for accessing the movement (6). Also, as the provision (22) is concealed due to complementary engagement between the locking member (19) and the slit (18), such provision (22) may have ingress protection.

Referring now to Fig. 3b, the case body (1) may be defined with a pocket (13), to releasably accommodate the crown (14). The crown (14) may be externally coupled to the case body (1) of the casing assembly (100) for selectively operating the movement (6) and in-turn operate aspects indicated by at least one of hands of the timepiece (200) and displace on the dial (7). The crown (14) may be coupled to the movement (6) through the stem (15), where the stem (15) may be inserted into the case body (1) via the pocket (13). In the illustrative embodiment, the pocket (13) is laterally defined between the first step portion (3) and the second step portion (4) such that, the stem (15) is removably accommodated to connect the movement (6) and the crown (14). Such pocket (13) may also be defined between the second step portion (4) and the third step portion (5) with no substantial changes in operation of the movement (6) or the crown (14), by means of a connecting element such as a gear mechanism. Also, positioning of the crown (14) may be based on design requirements and/or aesthetical appearance of the timepiece (200). In an embodiment, the stem (15) may be operatively coupled between the crown (14) and the movement (6) by means of a yoke [now shown in figures], where on operation of the crown (14), a resilient member (20), that may be accommodated in a compressed state within the crown (14), may be configured to displace the stem (15) to engage with the movement (6).

Referring to Figs. 3a and 3b, the provision (22) may be defined at such location that on accessing the provision (22), at least some elements associated with the movement (6) may be operated. In an embodiment, the provision (22) may be defined along the slit (18) of the base dial (16) in such a way that introduction of the tool into the provision (22) may engage some of the elements including, but not limited to, yoke, gears, and other components disposed in the casing assembly (100) and capable of affecting operation of the movement (6) and/or the crown (14), via the stem (15). On disassembling the bezel (8) and the dial ring (17) for introducing the tool into the provision (22), the stem (15) may be selectively disengaged from the movement (6) when the tool may be operated within the provision (22). Such disengagement of the stem (15) may be configured to allow the resilient member (20) within the crown (14) to actuate from pre-compressed state, whereby dislodging the crown (14) from lateral side of the case body (1). Such dislodgement of the crown (14) may allow servicing and maintenance of the crown (14) and/or stem (15) of the timepiece (200). Also, such configuration may allow ease in installation and disassembly of the crown (14) and the stem (15) without requirement of skilled operator.

In an embodiment, for operating the movement (6) and in order to adjust and/or calibrate functions such as, but not limited to, time, date, day, month, and the like, the stem (15) may be provisioned. The stem (15) may be coupled to the pocket (13) by a transitional fit, in order to avoid chip-off of the case body (1).
With such configuration of the casing assembly (100) having the case body (1) with integrated back cover portion (2), cost associated with at least one of manufacturing-lead-time, machinery costs, assembly-lead-time, material and wastage of the timepiece (200) is reduced.
In an embodiment, by integrating the back cover portion (2) with the case body (1) and defining the first step portion in the case body (1), thickness of the timepiece (200) may be minimized thereby rendering aesthetic design for such timepiece (200).
In an embodiment, as the back cover portion (2) is integrated with the case body (1), the movement (6) secured within the first step portion (3) may be substantially free from any vibrations experienced from the back cover portion (2).
It should be construed that the various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.

EQUIVALENTS
With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.

It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation, no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general, such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”

In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.

While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art.
