Abstract
A rotary card holder comprises a rotary card wheel, which at its respective opposite ends is non-rotatably secured to hand wheels, with a stationary axle, about which the card wheel rotates, extending through the card wheel and the hand wheels and having secured non-rotatably to its opposite ends respective end caps with which respective free ends of a wire support frame are non-rotatably secured. Each end cap carries a flexible polypropylene strip which has a free end extending from the periphery thereof to engage in a selected one of a series of grooves in the inside periphery of the hand wheels. In this way the card wheel is retained in its adjusted position each time it is adjusted and a ‘clicking’ indication is produced during adjustment.
Description
This invention relates to a rotary card holder having a rotary member in the form of a card wheel which is manually rotatable about a horizontal axis and carries a multiplicity of loosely mounted cards which contain information such as names, addresses and telephone numbers. The cards are sequentially presented to the view of a user as the card wheel is rotated, and are conveniently arranged with the information in some order, for example alphabetically.
It is known with such a rotary card holder to provide means for retaining the card wheel in the position to which it has been turned, against, for example, the force of gravity acting on the greater number of cards which are on one side of the wheel than the other. Moreover in moving the wheel from one retained position to another, there is normally heard an associated audible indication, typically a clicking sound.
An object of the invention is to provide a rotary card index in an effective and convenient manner.
According to the invention, a rotary card holder comprises a rotary member mounted by a support assembly for rotation relative thereto and having means for holding a plurality of cards, in use, manually operable means for turning the rotary member, and flexible means, between the support assembly and said manually operable means or said rotary member, the flexible means retaining the rotary member in a position to which it has been turned, in use, by said manually operable means, and/or producing an audible indication as the rotary member turns, in use.
As used herein, the term ‘cards’ includes not only conventional index cards and dividers, but also equivalently notched holders, for example for business cards.
Preferably the manually operable means is a hand wheel non-rotatably fixed to the rotary member. Desirably the hand wheel is at one end of the rotary member and at its side remote from said one end there is part of said support assembly, said flexible means acting between said hand wheel and said part of the support assembly. Conveniently said part of the support assembly is an end cap which protrudes into an outer open side of the hand wheel, and advantageously has said flexible means fitted at an inner side thereof received within said hand wheel. More preferably the flexible means is a polypropylene strip and most preferably it has a free end which interferes with projections around an inner periphery of the hand wheel, when the rotary member is turned, in use, by the hand wheel, to produce said audible indication. Said free end of the strip is disposed between a pair of adjacent ones of said projections when it retains the rotary means in a position to which it has been turned, in use. More conveniently the strip is folded into a V-shape to provide two such free ends, which are disposed between respective pairs of adjacent ones of said projections to retain the rotary member in an adjusted position.
The support assembly more desirably comprises a wire frame, and in one embodiment it has respective free ends engaged with respective end caps at opposite ends of the rotary member.
The invention will now be described, by way of example, with reference to the accompanying drawings, in which:

One embodiment of a rotary card holder
10
of the invention is shown in FIG.
1
. As can be seen therefrom, the holder
10
comprises a support assembly, denoted generally by the numeral
11
, which mounts, for rotation about a horizontal axis, in use, a rotary card wheel
12
, which at its respective opposite ends has manually operable hand wheels
13
,
14
for turning the card wheel
12
to present different ones of the cards
15
carried on the wheel
12
to be presented in an upright disposition to the user. As can be seen from
FIG. 1
, different series of cards
15
can be separated by suitable dividers
16
also carried on the wheel
12
, these being identified by respective tabs
17
along their longer outer edge. The support assembly
11
comprises a configurated wire frame
18
together with a pair of end caps
19
,
20
respectively at the opposite free ends of the frame
18
, with an axle
12
a
connecting the two end caps together and extending through the card wheel
12
which turns thereon.
The frame
18
, which is preferably formed of chrome-plated 5 mm mild steel wire or rod, is configurated as shown in
FIGS. 2
to
5
, the frame being symmetrical about a longitudinal central axis thereof. Instead of wire or rod, the frame could be tubular.
Accordingly it can be seen that the frame is formed with a relatively large U-shaped base portion
21
, which is received, in use, on the surface which supports the holder. At the free end of each arm of the U-shaped portion
21
there is an upwardly extending smaller generally C-shaped portion
22
, which as it extends further upwardly from its associated leg of the base portion
21
is deformed sidewardly and outwardly as shown best in FIG.
3
. From the end of the portion
22
remote from the base portion
21
, there then extends an upwardly curving portion
23
which has a hooked end
24
as shown best in FIG.
4
. As described, the frame
18
is symmetrical so that the portions
22
to
24
described at one side of the frame are mirrored at the opposite side thereof.
As will be explained hereinafter, the hooked ends
24
of the frame
18
engage with the respective end caps
19
,
20
which are outermost at the respective opposite sides of the holder
10
, so that, in contrast to known rotary card holder arrangements, the hand wheels
13
,
14
, are disposed inwardly of the respective opposite sides of the frame at the rotary card wheel.
FIG. 6
shows the general assembly of the card wheel
12
, hand wheels
13
,
14
and end caps
19
,
20
.
The card wheel
12
is, in this embodiment, formed by two separate identical half-wheels
25
. Each half-wheel is generally cylindrical and substantially hollow, being formed of injection moulded translucent polystyrene. Each half-wheel
25
is formed at one of its ends with an arrangement of recesses and projections, and in this way when the two half-wheels
25
are placed together as shown in
FIG. 6
, with these ends respectively abutting, but with one half-wheel displaced angularly relative to the other one, these ends interfit, as shown in
FIG. 6
, to form the composite card wheel
12
. From
FIG. 6
it can be seen that the conventional form of annular hard holding projection
26
is integrally formed on the exterior surface of each half-wheel
25
, this projection extending radially therefrom around said exterior surface. In this way the respective projections
26
on the two half-wheels
25
are spaced apart by the distance corresponding to the spacing apart of the pair of notches in each of the cards
15
or dividers
16
. Although the nature and construction of the card wheel does not form part of the present invention, it will of course be appreciated that this can be of any convenient form and can, for example, be wholly conventional. However in one embodiment of a card wheel of the invention, it could be arranged that the half-wheels are reversible so as to alter the spacing between the pair of card holding projections so as to allow the use of different cards with the rotary card holder.
As can be seen from
FIG. 6
, the other end of each half-wheel
25
is formed with a central, coaxial spigot
27
which is of reducing diameter towards its free end. Each half-wheel
25
has a central circular section bore
28
therethrough, each bore extending through the spigot
27
and defining a central longitudinal axis of the card wheel
12
. The section shown in
FIG. 6
is through upper and lower flanges in each of the half wheels.
As can be seen from
FIGS. 6
to
13
, each end cap
19
,
20
is in the form of a knob having an outer generally convex surface
29
which merges with a short cylindrical outer wall section
30
which is stepped down as it extends away from the surface
29
to form an annular flange
31
, the stepping down defining an outwardly facing annular surface
32
thereof, and the flange
31
being at the inner free end of the end cap. Each end cap, like each half-wheel
25
, is preferably formed of injection moulded polystyrene.
Within the annular flange
31
, each end cap is formed with a central cylindrical hub part
33
from which a series of angularly spaced ribs
34
radially extend to the flange
31
. As shown in the drawings, there are, in this embodiment, nine ribs
34
generally equi-angularly spaced around the hub part
33
. For one pair of adjacent ribs
34
, denoted by the numerals
34
a
and
34
b,
each rib, at its outer end, merges with the flange
31
rather than extending thereto. As a consequence the angular rib
31
is interrupted between these two ribs
34
a
and
34
b.
However as best shown in
FIG. 11
, the space between these ribs contains a projection
35
in the form of an isosceles triangle, which, as shown best in
FIGS. 12 and 13
, has the same axial depth as the ribs
34
a
and
34
b.
However the projection is sized so as not to fill the space between these ribs, but to leave a channel
36
of inverted V-shape around the projection
35
with the two ribs lying parallel to the respective equi-length sides of the projection
35
. In each limb of the V-shaped channel, integral small elongated projections, pips or the like
37
are provided at opposite sides thereof, i.e. on the side of the projection and facingly on the side of the rib, for a purpose to be described hereinafter. These pips
37
can be of any suitable form, could be arranged at one side of each limb only or could be staggered alternatingly on the two facing sides. Between each pair of pips
37
is a support column
37
a
which terminates short of the outer ends of the pips to provide a flat location/support, also for a purpose to be described hereinafter.
It can also be seen from the Figures, and in particular from
FIG. 13
, that at respective equal angles from the outer sides of said ribs
34
a
and
34
b,
the flange
31
is interrupted by respective straight openings
38
,
39
which are parallel to one another and to a plane bisecting said projection
35
. Finally with regard to the structure of an end cap, it can be seen from
FIG. 6
that the bore within the hub part
33
is stepped downwardly towards its blind end. Within this bore is received a friction cap
12
b
to engage the end of the circular-section axle
12
a
which has its opposite ends received in said friction caps in the end caps respectively and extends through the intervening card wheel
12
formed by the two half-wheels
25
, so that this axle is non-rotatably held by the end caps, which are part of the stationary frame assembly, the hand wheels
13
,
14
and the card wheel
12
being turned, in use, about said axle and thus relative to the axle and said end caps.
As can be seen to some degree from
FIG. 1
, the frame
18
engages each of the end caps by virtue of its hooked end
24
being received around the outer surface of the flange
31
and with its inwardly directed terminal portions of the hooked ends
24
extending through one of the openings
38
,
39
for the respective end caps
19
,
20
. By providing two such openings, symmetrically at opposite sides of the pair of ribs
34
a
and
34
b,
it is ensured that the two end caps are interchangeable, i.e. can be used at either end of the card wheel. Thus for the frame
18
, one of its terminal end parts will extend through an opening
38
in one end cap, while its other terminal end will extend through an opening
39
in the other end cap, thereby making it unnecessary to produce the end caps in handed form. The ‘springiness’ of the wire forming the frame
18
and the radius of curvature of each hooked end relative to the flanges
31
, is such that it is ensured that the frame is a close fit on each end cap.
Each of the hand wheels
13
,
14
is also preferably formed of injection moulded, translucent polystyrene and is in the form of a generally cylindrical wheel or knob which has knurling
40
around its outer periphery to enable it to be manually gripped and rotated, as previously described, in order to turn the card wheel
12
. As can be seen from
FIGS. 6 and 14
to
16
inclusive, each hand wheel has a generally hollow interior, and at its centre there is a circular hollow boss
41
which extends to both sides of the cylindrical wall
42
which, in use, as shown in
FIG. 6
, forms an inner wall for each hand wheel in that it is against this wall that one of the half-wheels
25
abuts.
As can be seen from
FIG. 6
, each of the hand wheels is fitted to an associated one of the half-wheels
25
by virtue of the spigot
27
of the half-wheel
25
being received as a tight fit within the boss
41
of the hand wheel. An additional connection between the hand wheel and the half-wheel is by way of respective parts of the upper and lower flanges of the half-wheel being received in diametrically opposed slots
43
,
44
through the part of the boss
41
extending exteriorly of the wall
42
. As previously mentioned, the axle which extends between the two end caps will also extend through the spigots
27
, and thus, in effect, through each hand wheel. At its end remote from the wall
42
, the annular peripheral inner surface of the hand wheel is formed with a multiplicity of V-shaped grooves
45
between respective projections. In the embodiment shown in detail in
FIG. 17
, each groove is fairly shallow, and in a preferred embodiment of the invention, there are
27
such grooves, each of which, as will be described, defines a location for retention means for holding the rotatable hand wheel relative to the stationary frame, in effect an end cap, when the card wheel has been turned to a desired position. This is necessary, for example, if by reason of the pivotal mounting of the cards on the card wheel, there is a greater mass of cards on the side of the card wheel on which the cards are being lifted. Accordingly if the card wheel is manually turned and then released, the action of gravity on the cards would tend to turn the card wheel in the reverse direction until equilibrium is achieved.
The retention means is shown in
FIGS. 12 and 13
, and, in this embodiment, is in the form of a flexible strip
46
, of polypropylene or other suitable material, which is folded into an inverted-V configuration and pushed into the channel
36
to be held by virtue of the pips, these retention means being provided at at least one end cap. It will be appreciated that the pips
37
are dimensioned and arranged so as to ensure that the strip is tightly held within the channel against any tendency to work loose during relative rotation between the hand wheel and its adjacent end cap. The strip
46
locates against the columns
37
a
so that its outer flat edge lies flush with the outer faces of the ribs
34
a,
34
b
and of the projection
35
, as shown in FIG.
13
.
As shown in
FIG. 13
, the strip is of a length such that when it is inserted in the channel the respective ends of both its limbs extend beyond the outer surface of flange
31
, and indeed beyond the boundary defined by the outer surface of the wall section
30
. Accordingly, as can be envisaged from
FIG. 6
, the two free ends of the strip extend to the grooves
45
of the hand wheels, and indeed each limb of the strip is of a length so that it extends into the deepest part of each groove. The angle of the channel, and thus the angle between the limbs of the strip, can be of any suitable value, and thus the number of grooves between the two ends of the strip is not crucial. However generally there would be at least one empty groove, or more likely two or three empty grooves, between the grooves into which the respective free ends of the strip are received in any one ‘retained’ position of a hand wheel relative to an end cap.
Accordingly it will be appreciated that generally when the rotary card wheel is turned by virtue of one or both of the hand wheels
13
,
14
, the or each hand wheel will be brought to a position where the respective ends of the strip
46
are received in respective ones of the grooves
45
. If movement of the hand wheel is stopped with the respective ends of the strip out of grooves
45
, then the resilience/flexibility of the strip may well be such that it will force the hand wheel slightly backwardly or forwardly until the ends of the strip move into the respective nearest grooves, thereby retaining the card wheel in position. When the card wheel is turned to a different position, it will be appreciated that the flexibility/resiliency of the respective ends of the strip are such that these ends will snap/click over the projections, i.e. the raised portions or lands between respective grooves, these ends snapping back into grooves successively until the final adjusted position is reached, as described above.
The invention provides an efficient and effective manner of retaining the card wheel, and thus the cards carried thereon, in a selected viewable position. However the arrangement is also such that the effective retention by way of the strip
46
is nevertheless easily overcome by rotating the manually operable hand wheels until the next desired adjusted position is reached, whereupon the retention means again act securely to hold the hand wheels, and thus the card wheel, in position. It will be appreciated that the number and design of the grooves
45
can be varied as required.
In addition to providing the retention described, the strip
46
also provides a further function which has been found to be desirable with users of rotary card holders, namely an audible indication of the adjustment, in the form of a clicking which accompanies the ratchet action of the respective ends of the strip as they successively move into and out of the grooves
45
. In addition to the retention action described, there is thus disclosed a convenient and effective way of providing this clicking noise. However it is to be noted that in alternative embodiments the flexible/resilient means could be arranged to provide only the retention/location, or only the audible indication, with other suitable means providing the other feature.
As well as carrying conventional suitably notched index cards and the like, including dividers, it is also envisaged that in a similar manner the card wheel can carry suitably notched plastics sleeves for holding conventional business cards or the like.
A further feature of the rotary card holder described and illustrated herein is the provision of an identity tag in the form of a (stabilising) foot
47
, shown in
FIG. 3
only, which is attached to the curved part of the base portion
21
of the frame
18
. This foot can be, for example, of transparent or coloured plastics material and can be shaped so as to act as an additional form of support receiving the weight of the holder. It is intended that this foot would bear the name of the manufacturer of the holder or some other identifying information.
It will be appreciated that alternatively the retention means could act between the end cap(s) and the card wheel itself, instead of the hand wheel(s) fitted thereto. Moreover, the retention means could be fitted to the hand wheel(s) or the card wheel, instead of to the end caps.
