Abstract
An image display device includes a base. A proximal panel is connected to the base by a spring-loaded hinge and has an image display area. A distal panel is connected directly or indirectly to the proximal panel via a spring-loaded hinge and also has an image display area. A catch co-operates with the base and the distal panel to release the proximal and distal panels from a storage configuration alongside the base to be moved by action of the spring-loaded hinges to a display configuration.
Description




BACKGROUND OF THE INVENTION




The present invention relates to image display panels. More particularly, although not exclusively, the invention relates to a hingedly articulated photo display or mirror panel device having spring-loaded dampened hinges connecting two or more fold-down panels. One or each panel might display a photograph or other graphic image or a mirror pane for example.




It is known to provide photo frames, personal mirrors, electronic calculators, and digital clocks for example in the form of a fold-down device. Such devices include a support base from which the display panel pivots upon a spring-loaded dampened hinge. However, where one might desire to display several photographs, graphic images, electronically generated images, or such images as well as another image such as a reflection in a mirror, a more advanced system would be needed in order to obviate the need for multiple discreet space-wasting devices.




OBJECTS OF THE INVENTION




It is the object of the present invention to provide an improved device comprising multiple panels hingedly interconnected for displaying images.




DISCLOSURE OF THE INVENTION




There is disclosed herein an image display device comprising:




a base,




a proximal panel connected to the base by a spring-loaded hinge and comprising an image display area,




distal panel connected directly or indirectly to the proximal panel via a spring-loaded hinge and also comprising an image display area, and




a catch releasably attaching the distal panel to the base and activatable to release the proximal and distal panels from a storage configuration at the base to be moved by action of the spring-loaded hinges to a display configuration.




Preferably the hinges each comprise co-linear cylinders connected by a shaft.




Preferably the shaft is connected to a coil spring that is located within one of the cylinders to rotationally bias the other cylinder.




Preferably there is a viscous lubricant between the shaft and said one of the cylinders.




Preferably the other of said cylinders has a non-circular hollow co-operating with projections of the shaft so as to rotate therewith.




Preferably the device further comprises an end cap attached to the shaft through an end of said other of the cylinders.




Preferably the end cap comprises a projection that co-operates non-rotationally with the projections of the shaft.




One or each said image display area might receive a photograph or a mirror.




Preferably the proximal and distal panels are received within the base when in the storage configuration.




Preferably the catch is attached pivotally to the base and comprises a lip that co-operates with an edge of the distal panel.

FIGS. 1 and 2

in a closed configuration.











DESCRIPTION OF THE PREFERRED EMBODIMENTS




In the accompanying drawings there is depicted schematically a display panel device


10


. Device


10


is typically fabricated from moulded plastics material, but might alternatively be formed of machined aluminum, brass or stainless-steel for example.




The device


10


includes a base


11


having a pair of parallel sidewalls between which hingedly articulated display panels


12


and


13


can be received when folded down into a closed configuration.




A hinge


14


attaches the proximal display panel


12


to the base


11


. Another hinge


15


attaches the distal display panel


13


to the proximal panel


12


.




Each hinge


14


,


15


comprises an inboard cylindrical portion or portions


19


formed integrally with the base


11


(or the lower end of the distal panel


12


as the case may be) flanked by a pair of outboard cylindrical portions


20


attached to the lower end of the proximal panel


12


(or its upper end). A hollow shaft


18


fits within each inboard cylindrical portion


19


. Located within each shaft


18


there is a coil spring


17


. One end of the coil spring


17


is attached to the interior of the respective inboard cylindrical portion


19


and the other end is attached to the interior of the respective shaft


18


. Remote ends of each shaft


18


have parallel projections


23


that are received within square openings


26


of the respective outboard cylindrical portions


20


. End caps


21


are fitted into the distal ends of the outboard cylindrical portions


20


and each comprise a projection


22


that fits between the projections


23


of the shaft


18


.




The springs


17


are pre-tensioned so as to bias the panels


12


and


13


toward the configuration depicted in

FIG. 2

in which the two panels are substantially co-planar. That is, the loading of the springs


17


causes rotation of the respective shafts


18


. Because the shafts


18


rotate in unison with the outboard cylindrical portions


20


, the panels are biased toward the open configuration. A viscous lubricant such as a synthetic white grease is applied between the exterior surface of the shafts


18


and the interior surface of the respective inboard cylindrical portions


19


. This provides dampening to the pivotal movement of the panels.




There is a catch


16


assembled upon the base


11


and the hinge


14


. The catch


16


includes opposed pins


23


to be received within holes


27


of the base


11


. The catch


16


also includes a lip


24


that fits over a recessed edge


25


of the distal panel


13


. The lip


24


can have a ramped top surface


30


to enable easy closing of the distal panel


13


.




There is a spring


28


formed integrally with the base


11


to bias the catch


16


into a position wherein the lip


24


extends over the edge


25


to thereby retain the panels


12


and


13


in a closed position against the bias of the is springs


17


. In order to release the panels


12


and


13


, finger pressure is applied to the catch


16


to release the lip


24


from the edge


25


.




There is also a catch mechanism at hinge


15


. The catch mechanisms comprises an edge


32


of the distal panel


13


alongside the hinge


15


that fits beneath a lip


31


extending between the side walls of the base


11


. When the catch


16


is activated to release the panels


12


and


13


, the springs within hinge


15


cause the distal panel


13


to pivot first. During this movement, the edge


32


disengages from the lip


31


to enable the proximal panel


12


to commence upward pivotal movement by action of the springs at hinge


14


.




The distal panel


13


might retain a mirror or a pane of glass


28


behind which a photograph for example might be retained. Likewise, the proximal panel


12


might retain a mirror or a pane of glass


29


.




It should be appreciated that modifications and alterations obvious to those skilled in the art are not to be considered as beyond the scope of the present invention. For example, further hingedly articulated panels can extend from the distal panel


13


to provide additional display areas.
