TECHNICAL FIELD OF THE INVENTION
[0001] The invention concerns an item dispenser with a bottom, a front and a rear end, and
two opposing sides and a movable item advancer included in a track in the bottom of
the item dispenser, a spring affecting the item advancer towards the front end, along
with a securing device for the item advancer located at the rear end. Item dispensers
of this type are used in connection with stands where they can be used to convey items
so that they are always at the front of the stand. Examples of items are packages
of cigarettes and cassette tapes.
STATE OF THE ART
[0002] Current item dispensers include an item advancer connected with a spring or similar
in order to move the products forward. This construction lacks a securing mechanism
which complicates replenishment of items. This problem becomes manifest when it is
desirable to replenish items from the back, which is most often the case.
[0003] There are also item dispensers with securing devices whose securing mechanism includes
hooks that are fastened in openings in the base of the construction. An item dispenser
of this kind is shown and described in GB 2290077A. Activation occurs by the item
advancer being displaced backwards so that the hooks release from the openings. This
means that the item dispenser is rendered inoperative in that the items are not automatically
moved forward unless the operator activates the spring by hand. The construction is
furthermore relatively complicated with various movable parts for achieving the securing
effect that leads to low operational safety and low cost effectiveness.
THE INVENTION IN SUMMARY
[0004] The present invention concerns redressing the problem of reactivation of item dispensers
and to provide an operationally safer and more cost effective item dispenser. In order
to provide this, the item dispenser includes - as have certain previous item dispensers
- an item advancer provided with a spring for advancement of items and a securing
device intended for the item advancer. The present invention is characterized in that
the securing occurs with the aid of a notch angled toward the front side in a track
in the bottom of the item dispenser. The notch is adapted to the item advancer that
can be secured on the notch. The notch is angled, which means that the item advancer
is angled in a corresponding manner when secured. The item dispenser is automatically
reactivated in connection with the final stage of replenishing in that the item advancer
is then automatically directed toward the front of the item dispenser when the last
item is pressed down between the second to last item and the item advancer.
[0005] In one embodiment the length of the item dispenser can be adjusted according to a
certain number of products so that the automatic release of the securing device is
more effective. The item dispenser can also suitably be designed as an integrated
unit complete with all required components. In another embodiment the item dispenser
can be designed to an adjustable length by designing the bottom in two interacting
parts.
[0006] No moving parts are used in the present invention to achieve the effect of securing
or release, so problems of operational safety and cost effectiveness are avoided.
The problem of reactivation of the item dispenser is eliminated, since this occurs
automatically when replenishment of items is completed. Further advantages with and
functions of the invention can be seen in the description below and in the accompanying
patent claims.
BRIEF DESCRIPTION OF THE DRAWINGS
[0007] The invention will be explained in more detail hereafter with reference to the drawings,
where
[0008] Fig. 1 is a schematic view from above of an empty item dispenser with the item advancer
in a forward position.
[0009] Fig. 2 shows the item dispenser in Fig. 1 partially filled with items and with the
item advancer in the secured position.
[0010] Fig. 3 is a longitudinal section view of the item dispenser in Fig. 1 without sides.
[0011] Fig. 4 is a rear view of the item dispenser in Fig. 1.
THE INVENTION
[0012] The embodiment of the invention shown in Figs. 1 and 2 is an elongated item dispenser
10 embodied with a bottom 11 and an item advancer 12. Bottom 11 is embodied so that
a track 13 is formed in the longitudinal direction in bottom 11. Track 13 runs from
a front part to a rear part of the item dispenser and is embodied so that item advancer
12 can run horizontally in the longitudinal direction of item dispenser 10. The longitudinal
sides of bottom 11 are provided with vertically positioned sides 23, 24 with front
tabs 25, 26. Bottom 11 and sides 23, 24 thus constitute an integrated unit. In one
embodiment bottom 11, sides 23, 24, and front tabs 25, 26 can be designed in one piece
from a suitable plastic material. In other embodiments sheet metal or similar rigid
material is used instead. Track 13 is provided with a notch 22 in the rear part of
one side of track 13.
[0013] Fig. 2 shows the item dispenser partially filled with items 27, and the item advancer
secured in notch 22. An additional item is indicated at 28. A cut away section of
the items at the front part of the item dispenser shows track 13 and a leaf spring
17.
[0014] Fig. 3 shows that item advancer 12 includes a level vertical plate oriented toward
the front part and with an upper portion 15 that is angled backwards. The vertical
plate 14 is positioned on a horizontal bottom plate 16. Item advancer 12 is further
provided with leaf spring 17 (see Fig. 2), or similar, the first end of which is fastened
in the front part of the item dispenser with aid of a suitable fastening device 18.
The other end of leaf spring 17 is positioned in a housing 19 located on bottom plate
16 behind plate 14 via an opening in the lower part of plate 14. Leaf spring 17 is
thus located so that item advancer 12 is under tension against the front part of item
dispenser 10.
[0015] Also with reference to Fig. 4, item dispenser 12 is provided with an L-shaped guide
rail 20, 21 positioned through the track on each respective side of the underside
of bottom plate 16. The vertical portion of guide rails 20, 21 is attached to the
under side of bottom plate 16 and the horizontal portion of guide rails 20, 21 extends
parallel with bottom 11. Guide rails 20, 21 and bottom plate 16 are thus located below,
respectively above, bottom 11 so that item advancer 12 can run horizontally in track
13 but not vertically. Plate 14, bottom plate 16, housing 19 with spring 17, and guide
rails 20, 21 form item advancer 12. In one embodiment item advancer 12 can be designed
in a suitable plastic material and leaf spring 17 designed in flexible metal.
[0016] Notch 22 is embodied so that item advancer 12 can be secured in notch 22 with aid
of the vertical portion of guide rails 20, 21. The front portion of notch 22 is furthermore
angled toward the front part of item dispenser 10 so that item advancer 12 when secured
is positioned on a slant toward the track.
[0017] Item advancer 12 is moved backwards when the item dispenser is loaded and is hooked
in notch 22. Items are filled from the top and suitably such that items already inserted
are moved forward toward front tabs 25, 26. When the item dispenser is filled up but
for the last item 28, it is situated as shown in Fig. 2. By then moving one more article
down to the position indicated at 28, item 28 will slide toward the angled upper portion
15 and push the whole item advancer in a rotating motion as indicated by arrow A.
With this motion the item advancer will be released from notch 22 and push items 27
toward front tabs 25, 26 because of the tension of spring 17.
[0018] The space for products in item dispenser 10, which extends from the rear part of
front tabs 25, 26 to the portion of notch 22 farthest toward the front, has the dimension
X. This distance X, that is shown in Fig. 1, can be adjusted for a specific number
of products for optimal automatic output efficiency of the securing device when the
item dispenser is full.
[0019] In an alternative embodiment not shown, bottom 11 with included sides 23, 24 and
front tabs 25, 26 can be manufactured in two interacting parts, a front part and a
rear part. The parts are arranged so as to be moveable with relation to each other
so that length X of the item dispenser 10 can be changed.
