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.
BRIEF DESCRIPTION OF THE DRAWINGS
A preferred form of the present invention will now be described by way of example with reference to the accompanying drawings, wherein:
FIG. 1
is a schematic perspective illustration of a hingedly articulated photo/mirror panel device in a partially opened configuration,
FIG. 2
is a schematic perspective illustration of the device of
FIG. 1
in a fully opened configuration, and
FIG. 3
is a schematic parts-exploded perspective illustration of the device of
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.
