Description

BACKGROUND

Wrist-worn devices are an important source of expression of individuality for both men and women. Wearers choose one or more wrist-worn devices to enhance personal style. Wrist-worn jewelry is commonplace among men and women. For example, bracelets allow a wearer some degree of personal expression. However, bracelets typically are static objects, and not capable of adapting to the wearer's mood, whims, etc. Even charm bracelets, which can be altered by addition of charms, typically do not allow for minute-to-minute personalization. Other user devices such as smart phones, smartwatches, and other wearable electronic devices allow for personalization using display screens (e.g., liquid crystal displays, organic light emitting diode displays, and the like). However, many wearers prefer mechanical devices for aesthetic reasons. Further, electronic devices may not be permitted in certain areas (e.g., high-security areas) and may not be practical for all applications (e.g., long times away from a charging device).

Accordingly, there is a need for improved customizability of mechanical wrist-worn devices. These and other difficulties are addressed in the following description.

BRIEF SUMMARY

It is to be understood that both the following general description and the following detailed description are exemplary and explanatory only and are not restrictive. Provided are wrist-worn devices.

In an aspect, a device can comprise a rotatable image wheel. The rotatable image wheel can comprise a plurality of image panels arranged radially around a central axis and radially offset relative to the central axis. The rotatable image wheel can also be rotatable about the central axis. The device can further comprise a face plate disposed coaxially with the rotatable image wheel and arranged to cover a portion of the rotatable image wheel. The face plate can describe an aperture radially offset with respect to the central axis. The device also comprises an actuator mechanically coupled to the rotatable image wheel and configured for causing rotation of the rotatable image wheel about the central axis relative to the face plate.

In another aspect, a device can comprise a first rotatable image wheel and a second rotatable image wheel.

The face plate can describe a first aperture aligned with at least a portion of the first rotatable image wheel and a second aperture aligned with at least a portion of the second rotatable image wheel. The device can also comprise an actuator mechanically coupled to at least the first rotatable image wheel. The actuator can be configured for causing rotation of the first rotatable image wheel about the first axis.

The present methods and devices may be understood more readily by reference to the following detailed description of preferred embodiments and the examples included therein and to the Figures and their previous and following description.

The wrist-worn device can be a purely mechanical piece of wrist attire, comprising no batteries or electronic displays. In some aspects, the wrist-worn device serves a purely decorative function, and does not tell time. In some aspects, the wrist-worn device can comprise a decorative face and one or more actuators or plungers that can be used to cycle through a plurality of visual effects on the face of the wrist-worn device.

In some aspects, the wrist-worn device is worn on a wearer's wrist, and allows the wearer to modify the image displayed by the device through actuation of an actuator or plunger on a periphery of the device. In some aspects, the device can include a face plate that comprises a relatively large, static image thereon. The face plate can describe one or more apertures. Each aperture can allow a portion of one or more rotatable image wheels to be visible therethrough on the watch face. The one or more rotatable image wheels can be rotated to customize the overall image presented by a combination of the face plate and the one or more rotatable image wheels and the face plate.

In some aspects, each one of the one or more image wheels can be separately controlled by a corresponding actuator or plunger. For example, a first image wheel can be controlled by a first actuator and a second image wheel can be controlled by a second actuator. In other aspects, the one or more image wheels can comprise a plurality of image wheels, and all of the plurality of image wheels can be controlled by a single actuator. For example, depressing the plunger can cause all of the plurality of image wheels to rotate. In some aspects, all of the plurality of image wheels can be rotated by the same amount each time the actuator is actuated (e.g., depressed). In other aspects, actuating the actuator can cause each of the plurality of image wheels to rotate by a different amount and/or at a different rate.

Turning now to FIG. 1, a first exemplary wrist-worn device 100 is shown. In some aspects, a housing or casing 102 can at least partially surround the device, exposing a face plate 104. In some aspects, the casing 102 can comprise a metal casing, such as stainless steel, titanium, aluminum, gold, silver, or alloys comprising one or more of those metals. In other aspects, the casing 102 can be formed from plastic, glass, ceramic, or other structurally sound materials. The face plate 104 can comprise a generally planar plate that covers at least a portion of the wrist-worn device 100. In some aspects, the face plate 104 can be generally circular. In other aspects, the face plate 104 can be generally rectangular, square, or any other shape. The face plate can comprise a decorative image.

In some aspects, the face plate 104 can further comprise an aperture 106. The aperture 106 can be radially offset from the center of the face plate 104. In some aspects, the aperture 106 can expose at least a portion of an image wheel 108. In some aspects, the aperture 106 can define a void in a material that forms the face plate 104. In other aspects, the aperture 106 can define a portion of the face plate 104 that is comprised of a transparent or semi-transparent material. The image wheel 108 can be a substantially circular wheel comprising a plurality of sections, with each section comprising a different image, pattern, and/or color. In some aspects, the different images, patterns, and/or colors on the image wheel 108 can be associated with the decorative image on the face plate 104. For example, the rotatable image wheel 108 can comprise a plurality of image panels arranged radially around a central axis and radially offset relative to the central axis. In some aspects, at least a portion of the image wheel 108 can be transparent or semi-transparent, allowing one or more designs covered by the image wheel 108 to be viewed by a viewer. In some aspects, the central axis of the image wheel 108 can be substantially orthogonal to a circular surface of the image wheel 108. The central axis of the image wheel 108 can be parallel with (e.g., extending in parallel, extending coaxially, etc.) an axis that extends orthogonally from the face plate 104. In some aspects, the central axis of the image wheel 108 can extend through a center of the face plate 104. In other aspects, the central axis of the image wheel 108 can be offset relative to the center of the face plate 104.

In some aspects, the image wheel 108 can be rotated by an actuator 110 in communication with the image wheel 108 and extending peripherally from the casing 102. The actuator 110 can facilitate rotation of the image wheel 108 about the axis. For example, actuation (e.g., depression) of the actuator 110 can cause the image wheel 108 to rotate by a predefined amount. In some aspects, the pre-defined amount can be associated with a number of sections of the image wheel. For example, when the image wheel 108 comprises four sections, each actuation of the actuator 110 can rotate the image wheel 108 by 90° (e.g., one quarter rotation). In other aspects, the image wheel 108 can be biased to rotate when not restricted by the actuator 110. For example, the image wheel 108 can be biased to spin using a bias spring, and prevented from spinning by a catch attached to the actuator 110. Actuating (e.g., depressing) the actuator 110 can disengage the catch allowing the image wheel 108 to spin until the actuator is de-actuated (e.g., until a wearer ceases to apply force to the actuator 110). In this way, the rotatable image wheel can be rotated randomly or pseudorandomly. In some aspects, the rotation can be caused by actuation of a mechanical movement by the actuator 110, as is known in the art. For example, the mechanical movement can comprise a ratchet wheel and spring.

In some aspects, the actuator 110 can be activated by a user. For example, the actuator 110 can be activated based on a user's mood, whims, feelings, etc. In other aspects, the actuator can be activated to select a color that suits the user's mood or coordinates with a user's clothing and/or accessories.

In some aspects, the face plate 106 and image wheel 108 can be covered by a lens 112. The lens 112 can be formed from glass, plastic, crystal, or other substantially transparent material. The lens 112 can be attached to the casing 102 to cover and help protect the face plate 104. In some aspects, the lens 112 can comprise a magnifying portion 114 radially offset with respect to the center of the lens 112 and at least partially aligned with the aperture 106.

In some aspects, the wrist-worn device 100 can further comprise a wrist strap 116 attached to the casing 102. The wrist strap 116 can be formed from any flexible material suitable for use securing the device to the wearer's wrist. For example, the wrist strap can be formed from one or more of leather, plastic, rubber, metal links, and the like.

FIG. 2 shows a second example of a wrist-worn device 200. In some aspects, a housing or casing 202 can at least partially surround the device, exposing a face plate 204. In some aspects, the casing 202 can comprise a metal casing, such as stainless steel, titanium, aluminum, gold, silver, or alloys comprising one or more of those metals. In other aspects, the casing 202 can be formed from plastic, glass, ceramic, or other structurally sound materials. The face plate 204 can comprise a generally planar plate that covers at least a portion of the wrist-worn device 200. In some aspects, the face plate 204 can be generally circular. In other aspects, the face plate 204 can be generally rectangular, square, or any other shape. The face plate 204 can comprise a decorative image.

In some aspects, the face plate 204 can further comprise a plurality of apertures 206. For example, the face plate can describe a first aperture 206a and a second aperture 206b. While FIG. 2 shows a face plate 204 comprising two apertures 206, more (or fewer) apertures are contemplated. Each of the apertures 206 can be radially offset from the center of the face plate 204. In some aspects, each of the apertures 206 can expose at least a portion of a corresponding image wheel 208. For example, the first aperture 206a can expose a portion of the first image wheel 208a, and the second aperture 206b can expose a portion of the second image wheel 208b. Each image wheel 208 can be substantially circular, comprising a plurality of sections with each section comprising a different image, pattern, and/or color. In some aspects, the different images, patterns, and/or colors on the plural image wheels 208 can be associated with the decorative image on the face plate 204. For example, the decorative image on the face plate 204 can comprise a face, with a first aperture 206a in a portion of the face where a mouth would conventionally be positioned, and a second aperture 206b where the eyes would conventionally be positioned; the first image wheel 208a can comprise a plurality of images of a mouth, disposed such that one of the plurality of images is viewable through the first aperture 206a; the second image wheel 208b can comprise a plurality of images of eyes, such that one of the plurality of images of eyes is viewable through the second aperture 206b. In some aspects, the first image wheel 208a and the second image wheel 208b can comprise different numbers of sections. For example, as shown in FIG. 2, the first image wheel 208a comprises three sections and the second image wheel 208b comprises two sections. In other aspects, the first image wheel 208a and the second image wheel 208b can comprise the same number of sections.

Each of the rotatable image wheels 208 can comprise a plurality of image panels arranged radially around a central axis and radially offset relative to the central axis. In some aspects, the central axis of each image wheel 208 can be substantially orthogonal to a circular surface of the image wheel 208. The central axis of the image wheels 208 can be parallel with (e.g., extending in parallel, extending coaxially, etc.) an axis that extends orthogonally from the face plate 204.

In some aspects, two or more of the plurality of image wheels 208 can be arranged concentrically. At least a portion of one or more (e.g., each) of the two or more image wheels 208 can be transparent or semi-transparent, allowing one or more designs covered by the image wheel 208 to be viewed by a viewer. In some aspects, the plurality of image wheels 208 can comprise wheels having differing radii, arranged concentrically such that the wheel 208 having the largest radius is furthest from the faceplate 204 and the wheel 208 having the smallest radius is nearest to the faceplate 204. In some aspects, the two or more concentric image wheels 208 can cooperate to display a single image.

In some aspects, each of the two or more concentric image wheels can be independently rotatable (e.g., the two or more concentric wheels 208 can be operably connected to independent corresponding actuators 210 to independently control each of the two or more wheels 208. In other aspects, each of the two or more concentric wheels 208 can be operably connected to a single actuator 210 that controls all of the two or more concentric wheels. For example, the actuator 210 can cause rotation of each of the two or more wheel 208 in the same direction or in different (e.g., opposing) directions and or in different amount (e.g., advancing a first wheel by one panel and a second wheel by two panels).

In some aspects, the image wheels 208 can be rotated by one or more actuators 210, each of the actuators 210 in communication with one or more of the image wheels 208 and extending peripherally from the casing 202. Each of the one or more actuators 210 can facilitate rotation of one or more of the image wheels 208 about their respective axes.

In some aspects, the one or more actuators 210 can comprise a single actuator. Actuation (e.g., depression) of the actuator 210 can cause the first image wheel 208a to rotate by a first predefined amount and the second image wheel 208b to rotate by a second predefined amount. In some aspects, the predefined amount can be associated with a number of sections of the corresponding image wheel. For example, when the first image wheel 208a comprises three sections, each actuation of the actuator 210 can rotate the first image wheel 208a by 120° (e.g., one third rotation). When the second image wheel 208b comprises two sections, each actuation of the actuator 210 can rotate the second image wheel 208b by 180° (e.g., one half rotation). In other aspects, the image wheels 208 can be biased to rotate when not restricted by the actuator 210. For example, the image wheels 208 can be biased to spin using a bias spring, and prevented from spinning by a catch attached to the actuator 210. Actuating (e.g., depressing) the actuator 210 can disengage the catch allowing the image wheels 208 to spin until the actuator is de-actuated (e.g., until a wearer ceases to apply force to the actuator 210). In this way, the rotatable image wheels 208 can be rotated randomly or pseudorandomly. In some aspects, actuation of the actuator 210 can cause rotation of each of the two or more wheels 208 in the same direction or in different (e.g., opposing) directions and or in different amount (e.g., advancing a first wheel by one panel and a second wheel by two panels). In some aspects, the rotation can be caused by actuation of a mechanical movement by the actuator 210, as is known in the art. For example, the mechanical movement can comprise a ratchet wheel and spring.

In other aspects, the one or more actuators 210 can comprise a first actuator and a second actuator. Actuation (e.g., depression) of the first actuator can cause the first image wheel 208a to rotate by a first predefined amount. Actuation of the second actuator can cause the second image wheel 208b to rotate by a second predefined amount. In some aspects, the first and second predefined amounts can be associated with a number of sections of the corresponding image wheel. For example, when the first image wheel 208a comprises three sections, each actuation of the first actuator 210 can rotate the first image wheel 208a by 120° (e.g., one third rotation). When the second image wheel 208b comprises two sections, each actuation of the second actuator 210 can rotate the second image wheel 208b by 180° (e.g., one half rotation). Alternatively one or more of the first image wheel 208a and the second image wheel 208b can be biased to rotate when not restricted by an actuator 210. For example, the first image wheel 208a can be biased to spin using a bias spring, and prevented from spinning by a catch attached to the first actuator 210. Actuating (e.g., depressing) the first actuator 210 can disengage the catch allowing the first image wheel 208a to spin until the first actuator is de-actuated (e.g., until a wearer ceases to apply force to the first actuator 210). The second image wheel 208b can be biased to spin using a bias spring, and prevented from spinning by a catch attached to the second actuator 210. Actuating (e.g., depressing) the second actuator 210 can disengage the catch allowing the second image wheel 208b to spin until the second actuator 210 is de-actuated (e.g., until a wearer ceases to apply force to the second actuator 210). In this way, one or more of the rotatable image wheels 208 can be rotated randomly or pseudorandomly.

In some aspects, the one or more actuators 210 can be activated by a user. For example, the one or more actuators 210 can be activated based on a user's mood, whims, feelings, etc. In other aspects, the one or more actuators 210 can be activated to select a color that suits the user's mood or coordinates with a user's clothing and/or accessories. In some aspects, a user may choose to activate all or less than all of the one or more actuators 210.

In some aspects, the face plate 206 and image wheels 208 can be covered by a lens 212. The lens 212 can be formed from glass, plastic, crystal, or other substantially transparent material. The lens 212 can be attached to the casing 202 to cover and help protect the face plate 204. In some aspects, the lens 212 can comprise a magnifying portion 214 radially offset with respect to the center of the lens 212 and at least partially aligned with the apertures 206.

In some aspects, the wrist-worn device 200 can further comprise a wrist strap 216 attached to the casing 202. The wrist strap 216 can be formed from any flexible material suitable for use securing the device to the wearer's wrist. For example, the wrist strap can be formed from one or more of leather, plastic, rubber, metal links, and the like.

FIG. 3 shows a second example of a wrist-worn device 300. In some aspects, a housing or casing 302 can at least partially surround the device, exposing a face plate 304. In some aspects, the casing 302 can comprise a metal casing, such as stainless steel, titanium, aluminum, gold, silver, or alloys comprising one or more of those metals. In other aspects, the casing 302 can be formed from plastic, glass, ceramic, or other structurally sound materials. The face plate 304 can comprise a generally planar plate that covers at least a portion of the wrist-worn device 300. In some aspects, the face plate 304 can be generally circular. In other aspects, the face plate 304 can be generally rectangular, square, or any other shape. The face plate 304 can comprise a decorative image.

In some aspects, the face plate 304 can further comprise one or more apertures 306. While FIG. 3 shows a face plate 304 comprising one aperture 306, more apertures are contemplated. Each of the apertures 306 can be radially offset from a center of the face plate 304. Each of the apertures can be included in the decorative image of the face plate 304. In some aspects, each of the apertures 306 can expose at least a portion of a corresponding image wheel 308. Each image wheel 308 can be substantially circular, comprising a plurality of sections with each section comprising a different image, pattern, and/or color. In some aspects, the different images, patterns, and/or colors on the image wheels 308 can be associated with the decorative image on the face plate 304. In some aspects, the image wheel 308 can comprise a central disc 308a and one or more annular portions 308b that surround the central disc. The one or more annular portions 308b and the central disc 308a can be arranged substantially coaxially.

Each of the central disc 308a and the one or more annular portions 308b can comprise a plurality of image panels arranged radially around a central axis and radially offset relative to the central axis. In some aspects, the central disc 308a and the annular portion 308b can comprise different numbers of sections. For example, as shown in FIG. 3, the central disc 308a can comprise three sections and the annular portion 308b can comprise two sections. In other aspects, the central disc 308a and the annular portion 308b can comprise the same number of sections. In some aspects, the central axis of each of the central disc 308a and the one or more annular portions 308b can be substantially orthogonal to a circular surface of the image wheel 308. The central axis of the central disc 308a and the one or more annular portions 308b can be parallel with (e.g., extending in parallel, extending coaxially, etc.) an axis that extends orthogonally from the face plate 304. In some aspects, the central disc 308a and the one or more annular portions 308b can be arranged concentrically. At least a portion of one or more (e.g., each) of the central disc 308a and the one or more annular portions 308b can be transparent or semi-transparent,

In some aspects, the central disc 308a and the one or more annular portions 308b can be rotated by one or more actuators 310, each of the actuators 310 in communication with one or more of the central disc 308a and the one or more annular portions 308b and extending peripherally from the casing 302. The one or more actuators 310 can facilitate rotation of one or more of the central disc 308a and the one or more annular portions 308b about their respective axes.

In some aspects, the central disc 308a and the one or more annular portions 308b can be independently rotatable (e.g., the central disc 308a and the one or more annular portions 308b can be operably connected to independent corresponding actuators 310 to independently control each of the central disc 308a and the one or more annular portions 308b). In other aspects, the central disc 308a and/or one or more of the one or more annular portions 308b can be operably connected to a single actuator 310 that controls the central disc 308a and the one or more annular portions 308b. For example, the actuator 310 can cause rotation of the central disc 308a and/or the one or more annular portions 308b in the same direction or in different (e.g., opposing) directions. Further, the actuator 310 can cause rotation of the central disc 308a and the one or more annular portions 308b by the same amount (e.g., advancing each of the central disc 308a and the one or more annular portions 308b by one section) or by differing amounts (e.g., advancing the central disc 308a by one section and the one or more annular portions 308b by two sections).

In some aspects, the one or more actuators 310 can comprise a single actuator. Actuation (e.g., depression) of the actuator 310 can cause the central disc 308a to rotate by a first predefined amount and the one or more annular portions 308b to rotate by a second predefined amount. In some aspects, the predefined amount can be associated with a number of sections of the corresponding image wheel. For example, when the central disc 308a comprises three sections, each actuation of the actuator 310 can rotate the central disc 308a by 120° (e.g., one third rotation). When the annular portion 308b comprises two sections, each actuation of the actuator 310 can rotate the annular portion 308b by 180° (e.g., one half rotation). In other aspects, the central disc 308a and the one or more annular portions 308b can be biased to rotate when not restricted by the actuator 310. For example, the of the central disc 308a and the one or more annular portions 308b can be biased to spin using a bias spring, and prevented from spinning by a catch attached to the actuator 310. Actuating (e.g., depressing) the actuator 310 can disengage the catch allowing the central disc 308a and the one or more annular portions 308b to spin until the actuator 310 is de-actuated (e.g., until a wearer ceases to apply force to the actuator 310). In this way, the central disc 308a and the one or more annular portions 308b can be rotated randomly or pseudorandomly. In some aspects, actuation of the actuator 310 can cause rotation of each of the central disc 308a and the one or more annular portions 308b in the same direction or in different (e.g., opposing) directions. In some aspects, the rotation can be caused by actuation of a mechanical movement by the actuator 310, as is known in the art. For example, the mechanical movement can comprise a ratchet wheel and spring.

In other aspects, the one or more actuators 310 can comprise a first actuator and a second actuator. Actuation (e.g., depression) of the first actuator can cause the central disc 308a to rotate by a first predefined amount. Actuation of the second actuator can cause at least one of the one or more annular portions 308b to rotate by a second predefined amount. In some aspects, the first and second predefined amounts can be associated with a number of sections of the corresponding image wheel. For example, when the central disc 308a comprises three sections, each actuation of the first actuator 310 can rotate the central disc 308a by 120° (e.g., one third rotation). When the annular portion 308b comprises two sections, each actuation of the second actuator 310 can rotate the annular portion 308b by 180° (e.g., one half rotation). Alternatively one or more of the central disc 308a and the one or more annular portions 308b can be biased to rotate when not restricted by an actuator 310. For example, the central disc 308a can be biased to spin using a bias spring, and prevented from spinning by a catch attached to the first actuator 310. Actuating (e.g., depressing) the first actuator 310 can disengage the catch allowing the central disc 308a to spin until the first actuator is de-actuated (e.g., until a wearer ceases to apply force to the first actuator 310). The annular portion 308b can be biased to spin using a bias spring, and prevented from spinning by a catch attached to the second actuator 310. Actuating (e.g., depressing) the second actuator 310 can disengage the catch allowing the annular portion 308b to spin until the second actuator 310 is de-actuated (e.g., until a wearer ceases to apply force to the second actuator 310). In this way, one or more of the central disc 308a and the one or more annular portions 308b can be rotated randomly or pseudorandomly.

In some aspects, the one or more actuators 310 can be activated by a user. For example, the one or more actuators 310 can be activated based on a user's mood, whims, feelings, etc. In other aspects, the one or more actuators 310 can be activated to select a color that suits the user's mood or coordinates with a user's clothing and/or accessories. In some aspects, a user may choose to activate all or less than all of the one or more actuators 310.

In some aspects, the face plate 306 and image wheels 308 can be covered by a lens 312. The lens 312 can be formed from glass, plastic, crystal, sapphire. or other substantially transparent material. The lens 312 can be attached to the casing 302 to cover and help protect the face plate 304. In some aspects, the lens 312 can comprise a magnifying portion 314 radially offset with respect to the center of the lens 312 and at least partially aligned with the aperture 306.

In some aspects, the wrist-worn device 300 can further comprise a wrist strap 316 attached to the casing 302. The wrist strap 316 can be formed from any flexible material suitable for use securing the device to the wearer's wrist. For example, the wrist strap can be formed from one or more of leather, plastic, rubber, metal links, and the like.
