BACKGROUND OF THE INVENTION
1. Field of Invention
This invention pertains to a display apparatus. More particularly, this invention pertains to a variably rotating display apparatus for displaying any of a variety of articles in a moving display presentation.
2. Description of the Related Art
Articles such as jewelry, rings, earrings, pendants, bracelets, watches, accessories and other items utilizing typically multifaceted gems, jewels, precious stones, imitation doublets, polished metals, mirrors and the like (hereinafter “articles”) are known in the art. These articles exhibit colors and brilliance unique to their shape and refractive properties when light is transmitted, refracted, or reflected in the articles, thereby giving aesthetic stimulations to those who see them. However, these articles cannot provide colors and brilliance unique to their shape and refractive properties unless light is transmitted onto the articles from the outside environment.
In marketing jewelry, one of the goals of on-sale display is to adequately demonstrate to the fullest extent the light capturing, reflecting, and refracting attributes of the article. Demonstrating the color and brilliance of stones used in accessory and jewelry items provides the prospective buyer of such articles an enriched buying experience and further increases the marketability of the articles. Conventional lighting in a static display environment does not allow such enhancement. Specifically, for a prospective purchaser to view the appearance of a stone's light, color and brilliance under a given lighting condition, the prospective purchaser must view the article subjected to the lighting condition from various directions, allowing the prospective purchaser the opportunity to view each of the capturing facets of the article in turn and to observe the way each facet gathers, reflects, and refracts the light from that particular lighting condition. Traditionally, in order to demonstrate all the various colors and refractive capabilities of an article held proximate a fixed light source, a prospective buyer must physically move around the article to view, in turn, each capturing facet as it reacts to the fixed light source.
This traditional method of requiring the prospective purchaser to move around the article poses problems in several marketing applications. For example, in the industry of television-based marketing of articles, such as television-based marketing of jewelry, the prospective purchaser shares the vantage point of the recording television camera. Therefore, for a television-based marketer to demonstrate all the various colors and refractive capabilities of and article held proximate a fixed light source, the marketer must physically move the recording television camera around the article. Such movement often necessitates continual repositioning of cumbersome recording equipment, and the complexity of such an undertaking can often result in degradation of the clarity and smoothness of the image display to the prospective purchaser.
BRIEF SUMMARY OF THE INVENTION
A rotatable article display device is disclosed. The device includes generally a platen defining a display surface, and a base for supporting the platen. The platen is adapted to rotate about an axis which extends perpendicular to the display surface. The platen is further adapted to rotate about a second axis.
In one embodiment, the base includes an inner yoke and an outer yoke. The inner yoke is pivotally mounted to the outer yoke such as to allow the inner yoke to rotate relative to the outer yoke about the second axis. A first drive mechanism is provided for rotating the inner yoke relative to the outer yoke about the second axis. The inner yoke supports the platen. A second drive mechanism is provided for rotating the platen about the first axis.
In certain embodiments, the position of the platen proximate the second axis is adjustable. In more discrete embodiments, a sighting mechanism is provided to identify the intersection between the first axis and the display surface.

DETAILED DESCRIPTION OF THE INVENTION
A rotatable article display device (hereinafter the “device”) and method for use is disclosed. The device, illustrated generally at 10 in the figures, provides a rotating display surface for displaying an article, including but not limited to a piece of jewelry, a gem, or similar such item, thereby allowing an unmoving observer to view a range of positions and lighting conditions of the displayed item.
FIG. 1 illustrates a perspective view of one embodiment of the device 10. Referring to FIG. 1, the device 10 includes generally a platen 28 defining a display surface 30, and a base 64 for supporting the platen 28. The platen 28 is adapted to rotate about a first axis 12 which extends perpendicularly to the display surface 30. As will be further discussed below, the platen 28 is further adapted to rotate about a second axis 14 which extends substantially parallel to the display surface 30.
In the illustrated embodiment, the base 64 includes an inner yoke 18 and an outer yoke 20. The inner yoke 18 is pivotally mounted to the outer yoke 20 such as to allow the inner yoke 18 to rotate relative to the outer yoke 20 about the second axis 14. In the illustrated embodiment, the outer yoke 20 supports and mechanically engages a first shaft 22 coaxially along the second axis 14. The first shaft 22 supports the inner yoke 18 in rotational connection to the outer yoke 20 about the second axis 14.
A first drive mechanism 24 is provided for rotating the inner yoke 18 relative to the outer yoke 20 about the second axis 14. In the illustrated embodiment, the first shaft 22 is fixed relative to the inner yoke 18. The first drive mechanism 24 is configured to rotate the first shaft 22, thereby causing rotation of the inner yoke 18 about the second axis 14. Referring to FIG. 2, in one embodiment the first drive mechanism 24 is configured to rotate a pinion 48, which in turn rotates a gear 60. The gear 60 is fixed to the first shaft 22. In this configuration, rotation of the pinion 48 by the first drive mechanism 24 results in rotation of the inner yoke 18 about the second axis 14. Those skilled in the art will recognize other suitable devices and configurations for establishing mechanical engagement between the first drive mechanism 24 and the inner yoke 18, and such devices and configurations may be used without departing from the spirit and scope of the present invention.
In the illustrated embodiment of FIG. 2, a stop 62 is provided to prevent the inner yoke 18 from rotating beyond a selected point. In this configuration, the first drive mechanism 24 is configured to oscillate the inner yoke 18 about the second axis 14. In another embodiment, the stop 62 is not included, and the first drive mechanism 24 provides complete rotational movement of the inner yoke 18 about the second axis 14.
Referring now to FIGS. 1 and 2, the inner yoke 18 supports the platen 28. A second drive mechanism 16 is provided for rotating the platen 28 about the first axis 12. In the illustrated embodiment the platen 28 is supported by a second shaft 50 which is interconnected between the platen 28 and the inner yoke 18. The second shaft 50 is configured coaxially along the first axis 12. The second drive mechanism 16 is configured to mechanically rotate the second shaft 50 about the first axis 12, thereby rotating the platen 28 about the first axis 12.
Those skilled in the art will recognize several devices suitable for use to accomplish the first and second drive mechanisms 24, 16 of the present invention, including but not limited to stepping motors, as well as other hydraulically, magnetically and electronically driven mechanisms. It will further be understood that a single mechanism, including but not limited to a gear system, pulley system, and other such mechanisms, may be used to accomplish both first and second drive mechanisms 24, 16 in an integral device, without departing from the spirit and scope of the present invention.
In several embodiments, the device 10 further includes a mechanism for adjusting the height of the display surface 30 relative to the second axis 14. Those skilled in the art will recognize numerous devices suitable for accomplishing such adjustability of the positioning of the display surface 30. For example, as better illustrated in FIG. 2, the inner yoke 18 of the present embodiment supports a positioning member 32. The positioning member 32 is adjustably secured to the inner yoke 18 such that the positioning member 32 is selectively repositionable relative to the second axis 14. The second shaft 50 is interconnected between the platen 28 and the positioning member 32. In this configuration, repositioning of the positioning member 32 relative to the second axis 14 results in repositioning of the display surface 30 proximate the second axis 14.
In the illustrated embodiment, a plurality of adjustable nut and bolt assemblies 34 connects the positioning member 32 to the inner yoke 18 such as to allow the positioning member 32 to be repositioned proximate the inner yoke 18. In another embodiment, the inner yoke 18 and the positioning member 32 are slidably attached. Those skilled in the art will recognize other suitable devices for use in establishing the adjustable connection between the inner yoke 18 and the positioning member 32.
FIG. 3 illustrates another embodiment of the device 10a. In this embodiment, the second shaft 50a is defined by a telescopically adjustable member having a proximal portion 52 and a distal portion 54. The proximal portion 52 is secured to the second drive mechanism 16 such as to allow the second drive mechanism 16 to rotate the proximal portion 52 about the first axis 12. The distal portion 54 is fixed to the platen 28. The distal portion 54 is in telescopic engagement with the proximal portion 52. An adjustable connector 56 is provided to allow the distal portion 54 to be selectively extended and retracted proximate the proximal portion 52 substantially along the first axis 12. In this configuration, the platen 28 is selectively repositionable proximate the inner yoke 18, thereby allowing the display surface 30 to be selectively repositionable relative to the second axis 14. Those skilled in the art will recognize various connectors, including clamps, frictional connectors, and other connectors suitable to accomplish the adjustable connector 56 of the present invention.
FIG. 4 shows an optional feature of the device 10 of the present invention. In the embodiment of FIG. 4, a sighting mechanism 42 is provided to identify the intersection between the first axis 12 and the display surface 30. In the illustrated embodiment, the sighting mechanism 42 is defined by a laser device 44. The laser device 44 is configured to project a laser mark 46 substantially downwardly and onto the display surface 30. The laser device 44 is configured such that the laser mark 46 appears at an intersection of the first axis 12 and the display surface 30 when the display surface 30 is rotated such that the first axis 12 is in a substantially vertical configuration. In another embodiment, the sighting mechanism 42 is defined by a scope sighted to visually indicate the location of the intersection of the first axis 12 and the display surface 30. Those skilled in the art will recognize other devices suitable for use to accomplish the sighting mechanism 42 of the present invention.
The sighting mechanism 42 allows a user to locate a point on the display surface 30 that intersects with the first axis 12. Once located, the user is able to position an article 58 on the display surface 30 in substantial alignment with the first axis 12. After positioning the article 58, the user is then able to adjust the positioning of the display surface 30 such as to bring the article 58 into substantial alignment with the second axis 14.
FIGS. 5 and 6 illustrate one method for using the device 10. As shown in FIGS. 5 and 6, an article 58 is positioned on the display surface 30, proximate the intersection of the first axis 12 and the second axis 14, using a suitable fastener, such as adhesive, hook and loop, clamp, or other such fastener. The user then adjusts the height of the display surface 30 to position the article 58 in a desirable configuration relative to the second axis 14. At least one lighting device 66 is provided in order to provide light to the display surface 30 and the article 58. The device 10 is then activated, including activation of the first and second drive mechanisms 24, 16. Upon activation of the first drive mechanism 24, the first drive mechanism 24 rotates the first shaft 22, which in turn rotates the inner yoke 18 about the second axis 14. Upon activation of the second drive mechanism 16, the second drive mechanism 16 rotates the second shaft 50. The second shaft 50 then mechanically engages the platen 28 to rotate the platen 28 about the first axis 12.
Referring to FIG. 5, a viewer 36 is shown, represented by a motion-picture camera positioned to record an image of the article 58 mounted to the display surface 30. For the sake of illustration, a television display 38 illustrating the specific view point 40 of the motion-picture camera is shown. FIG. 5 shows the device 10 with the first axis 12 beginning in a substantially vertical configuration, the second axis 14 in a substantially horizontal configuration, and the viewer 36 configured to view the article 58 along a line of sight substantially perpendicular to the second axis 14. In this configuration, the viewer 36 perceives the article 58 as being displayed from a side view. As shown in FIG. 6, as the display surface 30 rotates about both perpendicular and parallel axes 12, 14, the viewer 36 perceives the article 58 as both rotating and tilting, allowing the viewer (in the present illustration, the motion-picture camera) to view the article 58 from a variety of angles.
Referring now to FIGS. 5 and 6, in the illustrated embodiment, the first drive mechanism 24 is configured to oscillate the inner yoke 18. In operation, the first drive mechanism rotates the inner yoke 18 about the second axis 14 from a position in which the first axis 12 is substantially vertical (FIG. 5) to a position in which the first axis 12 is substantially horizontal (FIG. 6). Thereafter, the first drive mechanism 24 returns the inner yoke 18 to the position in which the first axis 12 is substantially vertical. In this configuration, the viewer 36 perceives the article 58 as though the viewer were beginning on one side of the article 58, flying through various points around the article 58, and landing on another side of the article 58, all the while viewing the article 58. In reality, of course, the viewer 36 remains motionless, while the device 10 moves the article 58 proximate the viewer 36, thereby creating such illusion.
FIGS. 7a-7l better illustrate the perception of the viewer 36 created through one embodiment of the method invention. In the embodiment of the method invention utilized in FIGS. 7a-7l, following placement of the article 58 on the display surface 30, the user adjusts the height of the display surface 30 to position the article 58 such as to substantially intersect with the second axis 14. The device 10 is then activated, including activation of the first and second drive mechanisms 24, 16, whereupon the viewer 36 views the display surface 30. In this configuration, as the display surface 30 rotates about both perpendicular and parallel axes 12, 14, the viewer 36 perceives the article 58 as though the viewer 36 were traveling throughout various points around the article 58, all the while viewing the article 58.
Those skilled in the art will recognize that the device 10 is capable of providing a variety of viewing presentations of an article 58 secured to the display surface 30. For example, in the illustrated embodiment, as the display surface 30 rotates about both perpendicular and parallel axes 12, 14, the viewer 36 perceives the article 58 as though the viewer 36 were flying in a spiral-shaped path from a point on one side of the article 58 to a point directly over top of the article 58 and viewing the article 58 from directly overhead (see FIGS. 7a-7f). As the display surface 30 continues to rotate about both perpendicular and parallel axes 12, 14, the viewer 36 then perceives the article 58 as though the viewer 36 were returning to the side of the article 58 along a similarly-shaped spiral path (see FIGS. 7g-7l).
FIGS. 8a-8l illustrate the perception of the viewer 36 created through another embodiment of the method invention. In this embodiment, following placement of the article 58 on the display surface 30, the user adjusts the height of the display surface 30 to position the article 58 such that the article 58 does not intersect with the second axis 14. In this configuration, when the device 10 is activated and the viewer 36 views the display surface 30, the viewer 36 perceives the article 58 as though the viewer 36 were flying in a spiral-shaped path from a point on one side of the article 58, to a point above yet slightly offset from the article 58 (see FIGS. 8a-8f). In the illustrated embodiment, the article 58 is initially positioned substantially above the second axis 14. As shown in FIGS. 8f and 8g, positioning the article 58 above the second axis 14 results in the article 58 appearing to offset substantially below the center of the image perceived by the viewer 36. Likewise, it will be understood by one skilled in the art that positioning the article 58 below the second axis 14 results in the article 58 appearing to offset substantially above the center of the image perceived by the viewer 36. As shown in FIGS. 8g-8l, as the display surface 30 continues to rotate about both perpendicular and parallel axes 12, 14, the viewer 36 then perceives the article 58 as though the viewer 36 were returning to the side of the article 58 along a similarly-shaped spiral path.
In yet another embodiment, the display surface 30 is configured to rotate first about the perpendicular axis 12, and then about the parallel axis 14. In this embodiment, as the display surface 30 rotates, the viewer 36 perceives the article 58 as though the viewer 36 were traveling in a circular path in the plane of the display surface 30 and then flying over the article 58, all while viewing the article 58. In still another embodiment, the viewer 36 is configured to view the article 58 along a line of sight which is not perpendicular to the second axis 14. In this embodiment, as the display surface 30 rotates about the second axis 14, the viewer 36 perceives the article 58 as though the viewer 36 were elevated above the article 58 and viewing the article at a downward angle. Those skilled in the art will recognize numerous other viewing presentations that the device 10 is capable of providing.
Those skilled in the art will recognize that either of the first and second driving mechanisms 24, 16 may be configured to oscillate or rotate corresponding shafts 22, 50 about respective axes 14, 12 without departing from the spirit and scope of the present invention. Similarly, it will be further understood that both first and second driving mechanisms 24, 16 may be configured to oscillate or rotate corresponding shafts 22, 50 about corresponding axes 14, 12.
From the aforementioned, it will be understood that the device 10 provides a variably rotating display surface 30, which rotates proximate an unmoving observer. As such, an observer of the display surface 30 is able to view a range of orientations of an item displayed upon the display surface 30.
While the present invention has been illustrated by description of several embodiments and while the illustrative embodiments have been described in considerable detail, it is not the intention of the applicant to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications will readily appear to those skilled in the art. The invention in its broader aspects is therefore not limited to the specific details, representative apparatus and methods, and illustrative examples shown and described. Accordingly, departures may be made from such details without departing from the spirit or scope of applicant's general inventive concept.
