This invention relates to the field of variable orientation display structures. In particular, the invention relates to a self-righting display assembly with an articulated mounting structure that permits the direction of a display to be varied about at least two orthogonal axes, thereby allowing the display to be oriented at any angle with respect to the vertical or horizontal planes to which it attaches.
There are at least two prior art clocks that allow the orientation of the clock to be varied and can be attached to a mounting surface. These systems include the “clock with holder” disclosed in U.S. Pat. No. 4,362,402 to Kallinke et al. and the “flex-clock with clip/stand,” model nos. FLCLC/S.
Kallinke discloses a clock fixed within a housing that is variably positioned between the arms of a V-shaped yoke. The inner surfaces of the yoke arms include a plurality of protrusions in the form of small detents and recesses that are adapted to engage corresponding recesses and detents, respectively, on the periphery of the clock housing. The clock housing is permitted to pivot with respect to the yoke about an axis created by two of a plurality of detents that engage the yoke on either side of the clock housing. The clock housing may rotate a total of approximately 90 degrees about the axis. One significant drawback of Kallinke's clock with holder is that the clock housing is restricted to rotate about one axis, generally described as the vertical axis or the horizontal axis, at any one time. Moreover, the angle of rotation of the housing about either axis is limited by the raised detents that physically obstruct and prevent the clock housing from rotating beyond the 90 degree angle.
The flex-clock with clip/stand, model FLCLC/S, includes a clock, fixed within a housing, attached to a clip or base by means of a flexible tubular structure. While the tubular structure permits the direction of the clock to be varied over a range of orientations relative to the clip or base, the flexible tubular structure fails to provide for pivotal movement between the clock housing and clip-type mounting structure. Nor does the clock have the ability to right itself which is important to maintain the clock face in position that is easily readable with minimal user intervention.
The present invention overcomes the limitations of the prior art with a display assembly comprised of a display that conveys graphical information generated by a display source; a display housing for receiving the display; self-righting means rotatably coupling the display and display housing; and a body operatively engaged to the display housing by a connecting means. The display source in some embodiments is an analog, or digital clock, calendaring device, temperature display, or other electromechanical display. In other embodiments, the display source generates advertising or promotional information, messages, or horoscopes, for example.
The self-righting means, when operatively coupled to the display, automatically maintains the display in a substantially upright position independent of the orientation display housing. The self-righting means in the preferred embodiment includes a bearing assembly and a biasing means for biasing the display into a substantially upright position. In the preferred embodiment, the bearing assembly includes a bearing and the biasing means includes a weight asymmetrically disposed with respect to the bearing's axis of rotation, although other structures including gyroscopes or position and motion actuators could be adapted to apply the torque necessary to bias the display.
The connecting means is comprised of at least one and preferably two pivotable connections that permit the display housing to swivel and or rotate with respect to the body, thereby allowing the display to be turned to face a viewer without repositioning the body. The connecting means, together with the self-righting means, enhances the readability or viewability of the display without the need to adjust the display housing so that the display is right-side-up. In the preferred embodiments, the connecting means is a cassegrain assembly that allows the display housing to swivel over 360 degrees through both a vertical plane and horizontal plane independently.
The body in some embodiments includes attaching means for permanently or removably affixing the display assembly to an object such as a smooth, planar surface. The attaching means in the first preferred embodiment is comprised of one or more suction cups, although clips, adhesive, and screws may be equally suitable.
In some embodiments, the display source includes a memory means capable of storing and recalling graphical or alphanumeric display indicia. The display source may further include a central processing unit for causing the indicia represented at the display to be varied over the course of time. The processing unit may, for example, cause the display to simultaneously or sequentially interleave images of the time in combination with advertising indicia. The assembly may further include an external communication means for operatively coupling to an external device from which display data is uploaded to the assembly's memory means.
The accompanying figures depict embodiments of the display assembly of the present invention, and features and components thereof. With regard to means for fastening, mounting, attaching or connecting the components of the present invention to form the apparatus as a whole, unless specifically described otherwise, such means are intended to encompass conventional fasteners such as machine screws, machine threads, snap rings, hose clamps such as screw clamps and the like, rivets, nuts and bolts, toggles, pins and the like. Components may also be connected by friction fitting, or by welding or deformation, if appropriate. Unless specifically otherwise disclosed or taught, materials for making components of the present invention are selected from appropriate materials such as metal, metallic alloys, natural or synthetic fibers, plastics, elastomers and the like, and appropriate manufacturing or production methods including casting, extruding, molding and machining may be used.
Any references to front and back, right and left, top and bottom, upper and lower, and horizontal and vertical are intended for convenience of description, not to limit the present invention or its components to any one positional or spatial orientation.

The display 104 in the preferred embodiment is an analog or digital display capable of conveying text, numerical, or graphical information. The display 104 may be implemented in combination with back-lighting or projection-lighting. The display in the preferred embodiment is an LCD display, although one skilled in the art will recognize the suitability of an LED or incandescent display.
The information represented on the display 104 is generated by the display electronics 105 operative couple to the display 104. In the preferred embodiment, the display source 105 includes solid-state electronics or mechanical means for generating the time. Preferably, the time is entered, set, programmed, or otherwise modified using an input means that may be accessible on the display housing 101, display source 105, or other position on the exterior of the display assembly 100.
In other embodiments, the display source 105 includes a central processing unit that generates or otherwise modifies the image depicted at the display 104 in a predetermined manner. The processing unit may, for example, cause the indicia represented at display 104 to be varied in time whereby a plurality of images elements are simultaneously or sequentially interleaved over the course of time. In some embodiments, the display 104 depicts the time which is periodically interrupted with an advertising slogan or message, for example.
In some embodiments, the display source further includes a memory means from which the central processing unit retrieves data stored therein, the data including the graphical or alphanumeric indicia to be presented at display 104. The memory means in the preferred embodiment is a ROM (read-only memory) that is programmed during the manufacturing process. In other embodiments, the memory means may include a PROM (programmable ROM) or EPROM (erasable PROM) that allow the memory to be one or more times after manufacture. PROM and EPROM are preferable in embodiments of the assembly that include an external communication means for operatively coupling to an external device through which data is uploaded to the memory means. A USB port, radio frequency, or infrared communication link are examples of suitable external communication means, although one skilled in the art will recognize the suitability of alternative implementations.
The display 104 is visible through the substantially transparent lens 103, which in some embodiments is a convergent lens capable magnifying the graphic information in the display 104 to increase its visibility and readability. The external surface of the display housing 101 is preferably substantially spherical in shape to facilitate handling by the user and minimize any external protrusions that might otherwise inhibit the 360 degree rotation of the housing 101 about the first axis 170. The spherical shape of the external surface of the convergent lens 103 preferably compliments and smoothly transitions into the external surface of the shell 102 of the display housing 101.
The self-righting means maintains the top of the display 104 in a substantially upright position relative to the bottom of the display 104 to enable a viewer to see and read the graphics represented on the display 104. In the first preferred embodiment, the self-righting means comprises a bearing assembly and weight 130 mounted off-center from the axis or rotation of the bearing assembly. In first preferred embodiment, the bottom of the display 104 is the side associated with the weight 130. Alternative self-righting means may be comprised of a gyroscope, motion-sensitive circuit, or electromagnetic controls to regulate the position and or direction of the display 104.
The bearing assembly in this embodiment is comprised of a mounting structure 108 that is rigidly affixed to the display 104 and a bearing casing 122 that is rigidly affixed to the housing 101. The mounting structure 108 and bearing casing 122 are adapted to engage one another by means of first set of ball bearings 126 held captive in the ball bearing races 109,123 and the second set of ball bearings 125 contained within the ball bearing races 110,124. The mounting structure 108 is permitted to rotate freely with substantially no resistance, thus permitting the weight 130 that is operatively coupled to the display 104 to exert a torque that causes the display to settle under the force of gravity into a substantially upright position virtually independent of the orientation of the display assembly 100. While the display 104 may be forced to assume and inclined position, the weight 130 will always urge the display 104 into a preferred orientation with respect to the vertical, unless of course the display is in a direction co-parallel with the force of gravity. One skilled in the art will recognize that assembly 100 is designed to prohibit the mounting structure 108 from sliding out or otherwise disengaging the bearing casing 122 during normal operation of the display assembly 100.
As illustrated, the display housing 101 is operatively coupled to the gantry 120 in this embodiment with co-axial pins 121 that permit the rotation of the housing 101 about the first axis 170. The pins 121 may be individual components or formed as an integral part of either the gantry 120 or the display housing 101. The second swiveling means is comprised of a post 129 integrally incorporated in this preferred embodiment to the gantry 120 and rotatably engaged to the body 150 in a manner that permits these elements to swivel relative to one another about the second axis 160. The post 129 preferably includes a locking head 128 that flexibly compresses during insertion of the post 129 into the body and then expands to inhibit the gantry 120 from separating from the body 150 under normal operating conditions. The first and second swivel means may alternatively be comprised of various hinges, a ball joint, or trunnion, for example. One skilled in the art will recognize that with two independent axes rotation, the housing 101 may be adjusted to face any angle about the horizontal or vertical planes.
In some embodiment, the attaching means permanently or removably affixes the assembly 100 to another object. As illustrated in the preferred embodiment, the attaching means is comprised of a pair of suction cups 151,152 that are secured to the body 150 by rods 153,154 and base plates 157,158 that are affixed to the housing 150 by means of screws 165 that threadedly engage the base receptors 161, 162, 163, 164.
The attaching means may further include an anchor pad 180 with cavities 181 that are adapted to slidably receive the suction cups 151,152 such that the anchor pad 180 engages the body 150. The pad 180 may then be secured to a surface or object by adhesive, screws goods sold under the trademark VELCRO, or the like. One skilled in the art will recognize the suitability of numerous alternative attaching means comprising, for example, one or more clips, springs, adhesives including adhesive pads, bolts, for example, used to directly or indirectly affix the body 150 to another object.
Illustrated in
The second preferred embodiment 200 further includes one or more grasping means including, for example, flexible members 290A and 290B with clasps 292A and 292B, respectively, for releasably securing various stationary or office-related products such as notes sheets 294. A flexible member 290A or 290B is preferably comprised of an elastic substance, including elastomer products or pliant wire or metallic links, that permit the clasps 292A and 292B to be repositioned at the convenience of the use. A clasp 292A or 292B preferably includes a clip, hook, binder, or fastener capable of holding or otherwise retaining the stationary or other article until the user disengages the product from the grasping device.
Although the above description contains many specifics, these should not be construed as limiting the scope of the invention, but rather as merely providing illustrations of some of the presently preferred embodiments of this invention.
