Description
TECHNICAL FIELD
[0001] The present invention relates to the rotating shelf
structure of a showcase in which goods sold are conveniently
replaced on the basis of the first-in first-out arrangement with
outside ones by rotating a goods display shelf. More specifically,
the present invention relates to the rotating shelf structure of a
showcase, which is characteristic in that the structure is
renovated to provide the durability, easy assembling, manufacturing
cost reduction, and smooth circulation of cold air while minimizing
the total shelf weight.
BACKGROUND TECHNOLOGY OF INVENTION
[0002] In general, on the shelves of refrigerating and freezing
showcases installed at supermarkets (convenience stores), a variety
of goods are displayed in multi layers so that purchasers may
identify and select them with convenience. In order to display more
goods, it is possible to adjust the height and gap of the shelf. In
a conventional reach-in-type showcase, opening/closing doors are
installed for easy carry-in and take-out at the front of the
box-form cabinet and many shelves are placed to load a lot of goods
inside the cabinet. In the said showcase, many installation grooves
are formed horizontally for attachment of brackets on the left and
right side walls inside the cabinet, and both ends of the shelf are
fixed into bracket installation grooves directly or by using clips
to load goods such as a variety of foods and drinks.
[0003] In case the said shelf is fixed horizontally, however, the
goods placed in the front may be easily identified by consumers,
but the ones placed away from the front should be taken out and
confirmed, one by one, by consumers, which causes inconveniences.
In addition, due to its state of being fixed, the said shelf has a
problem that it has limitation in displaying the goods placed away
from the front, which due to lack of the first-in first-out
arrangement, should be moved, one by one, by a manager to the front
empty space created by sale of the previous goods.
[0004] In order to solve the problem of the said conventional
fixed-type shelf, proposed is a rotating-type shelf which can
change the position of goods displayed on the showcase shelf. The
said rotating-type shelf was disclosed in Korean Utility Model
Registration Application No. 20-1997-0020218 ("Free Rotating-Type
Shelf Structure of Showcases"), Korean Utility Model Registration
Application No.20-1997-0020227 ("Rotating-Type Shelf of
Showcases"), Korean Patent Application No. 10-1997-0035897
("Rotating-Type Shelf Structure of Showcases"), and Korean Patent
Application No. 10-1997-0017474 ("Drive Equipment for Rotating
Shelf of Showcases"). The said shelf structure is a type with many
horizontal circular plates installed to load goods around the
central axis, and the goods to be selected reaches the opening
position of the door by rotating the circular plates round the
central axis by means of an artificial force or a drive motor. The
said rotating shelf is horizontal and cannot utilize the first-in
first-out arrangement. It also has an inconvenient problem that the
circular plates should be rotated for selection of goods directly
by consumes.
[0005] In addition, in order to solve the problem of the said
horizontal shelf, the shelf is inclined with a small angle so that
goods may always arrive at the tip on the basis of the first-in
first-out arrangement for their easy identification and selection
by purchasers. In other word, the next item slides down toward the
tip due to the slope of the shelf, if the purchasers take out an
item displayed on the tip of the shelf, The said conventional
inclined shelf has an advantage that goods slide down smoothly for
smooth movement of the next item displayed to the space of the
initial item selected on the basis of the first-in first-out
arrangement so that they may be easily identified by consumers.
Since it is fixed, however, the said conventional inclined shelf
has a problem that a large inflow space whose position is higher
than that of the goods placed on the tip is required to supplement
goods and so it is difficult to provide a large display space of
goods because the gap between display spaces is large. In order to
alleviate the said problem, a display space may be provided at the
rear of the shelf while the height gap between the shelves is
minimized. However, this approach also has a problem that due to
the increase in unnecessary spaces, more supply of cooling air is
required, which is uneconomical, and the installation place is
limited since the cabinet size increases.
[0006] Meanwhile, in order to solve the said problem, the applicant
of the present invention first applied for and registered Korean
Patent Application No. 10-2010-0017175 (Registration No.
10-1089752) `Rotating-Type Self Structure of Showcases`. The said
rotating-type shelf structure of the showcase (1) is composed, as
shown in Attached FIG. 1 (Disassembled Perspective Drawing of
Rotating-Type Shelf Structure) and FIG. 2 (Approximate Cross
Section of Showcase Equipped with Rotating-Type Shelf Structure),
of the cabinet (11), which provides a space for display at
refrigerating and freezing states, the door (12), which
opens/closes the opening part for display and sale of goods, and
the rotating-type shelf structure 100) installed to rotate in order
to display and take out goods on the basis of the first-in
first-out arrangement.
[0007] A detailed examination of the said rotating-type shelf
structure (100) indicates that it is composed of the base plate
(2), which is fixed on the floor inside the cabinet (11) and
equipped with the bottom axis (21) at the center, the bottom plate
(3) with
##STR00001##
form on which the bushing (31) inserted into the bottom axis (21)
of the base plate (2) is installed, many ball castors (32) are
installed at the bottom, the pillar frame (4) wherein many first
fixing groove (41) and second fixing grooves (42) with hitch spot
(42'') are formed in equidistant intervals in pairs to insert the
both ends into the said bottom plate (3), the top plate (5) on
which the bushing (51) is installed at the central top contacting
the both ends of the said pillar frame (4) and the boundary part is
bended in the perpendicular direction, the fixing member (6)
wherein the upper part of supports (63) includes the fixing plate
(62) equipped with the top axis (61) which is inserted into the
bushing (51) fixed to the said upper plate (5) can be connected
after being inserted to the both ends of the fixing plate (62) to
fix the horizontal part (63a) and to fix the vertical part (63b) on
the walls of internal both sides of the cabinet (11), and the
display frame (7) which has in the front and rear direction the
cover (71) which maintains the state of penetrating the both ends
of fixing pin (72) of which both ends are hooked to the first
fixing groove (41) and the second fixing groove (42) of the sand
pillar frame (4) and wherein the boundary part are vertically bent.
And the said display frame (7) consists of polygons with a form
of
##STR00002##
whose front corner part, when rotating, locates the center of
rotation in front so that it may not touch the cabinet (11) wall
and whose rear corner part is corner-cut so that it may rotate
without contacting the cabinet (11) wall.
[0008] The said rotating-type shelf structure of showcases can make
the best use of the inner space of the cabinet by locating in front
the center of rotation of the display frame in which goods are
displayed for the first-in first-out arrangement and by
corner-cutting and rotating the rear of the display frame, enable
the first-in first-out arrangement by rotating the rear position of
the display frame to the opening position after opening the door
and supplementing goods conveniently from the outside, can make the
rotation smooth by bending/forming/assembling durable metal plate.
and can reduce the loss of cooling air by minimizing the cabinet
space.
[0009] However, the said rotating-type shelf structure of showcases
not only has an excessive weight due to the pillar frame, which
supports the vertical load transmitted from the goods and shelf,
and the structural characteristics of the display frame on which
goods are displayed, but also requires a large artificial force
action for shelf rotation, has a difficulty in smooth rotation due
to inflow of foreign substances to ball castors, and has a
difficult problem of assembling due to structural characteristics
of the fixed member.

DETAILED CONTENTS FOR IMPLEMENTATION OF INVENTION
[0036] Hereunder, to the same parts as the signs given in the
conventional technology of FIGS. 1 and 2, the same signs are given.
In reference to attached FIGS. 3 through 10, the desirable examples
of the present invention are described in detail.
[0037] FIG. 3 and FIG. 4 show the disassembled perspective drawing
and the cross-sectional drawing of the showcase-installed state,
respectively, for the rotating-type shelf structure of showcases
based on examples of the present invention. Sign 1 represents the
showcase, 11 the cabinet, 12 the door, and 100 the rotating-type
shelf structure.
[0038] Ordinarily, the showcase (1) consists of the cabinet (11),
which provides a space for display and sale of goods at
refrigerating and freezing conditions, and the door (12), which
opens/closes the opening part for display and sale of goods.
Cooling air is sullied to the inside of the cabinet (11) from an
non-diagrammed freezing system.
[0039] And inside the said showcase (1), installed for rotation is
the shelf structure (100) in which placed are many display frames
(7) inclined to display goods on the basis of the first-in
first-out arrangement inside the cabinet (11) of the said showcase
(1).
[0040] The goal of the shelf structure (100), the improved feature
technology of the present invention, is to provide a convenient
assembling, maintain the durability, reduce the cost, and provide
free rotation while minimizing the load. In order to accomplish
this goal, metal plates with the thickness ranging from 1 mm to 4
mm are used, bended, assembled, and disassembled to increase the
durability, and the display frame (7) improves the assembling
structure by changing the material to reduce the weight and provide
a smooth circulation of cooling air.
[0041] The shelf structure (100) of the present invention is
composed, as shown in FIGS. 3 and 4, of the base plate (2), which
is fixed to the internal floor and wall of the cabinet (11) and
supports the central axis of rotation, the fixing member (6), the
bottom plate (3) and top plate (5) for formation of the center of
rotation, the pillar frame (4) for fixing of the said bottom plate
(3) and top plate (5) to the top and bottom ends, and many display
frame (7) combined with the said pillar frame (4) to display goods.
These are combined by ordinary fixing bolts and tightening
screws.
[0042] The base plate (2) supports the total load of the shelf
structure (100) and the weight of displayed goods, is fixed on the
internal floor of the cabinet (11) by tightening screws, and the
bottom axis (21) is installed to the center. The said bottom axis
(21) is the central axis for rotation of the shelf structure (100).
Especially, the base plate (2) is formed into a circular plate
along the rotational radius of the bottom plate (3) to make no
hitches when the bottom plate (3) rotates and the border of this
circular plate is bended vertically to form the barrier (22).
[0043] The bottom plate (3) is inserted into the bottom axis (21)
of the base plate (2) and the bushing (31) is installed for smooth
rotation to the bottom center of the bottom plate (3). In order to
make the rotation more smooth and support the load, many ball
castors (32) are installed around the bottom and the boundary part
is bended in the perpendicular direction to form into the form
of
##STR00003##
with a narrow width on both sides. In addition, the bottom plate
(3) is constructed together with the base plate (2) to support the
entire load of the shelf structure (100) and the weight of
displayed goods.
[0044] The bushing (51) is installed to the top center of the top
plate (5) and the boundary part is bended in the perpendicular
direction to increase the durability.
[0045] Meanwhile, the insertion groove (33) and insertion groove
(52) are drilled in the front and at the rear, respectively, so
that No. 1 pillar and No. 2 pillar of the pillar frame (4), which
are formed in division on the bottom plate (3) and the top plate
(5), may be inserted into each insertion groove.
[0046] The pillar frame (4) is fixed to both ends of the bottom
plate (3) and the top plate (5) to form frames on left and right
sides in a group, and each pillar frame (4) is formed in division
into No. 1 pillar (4a) and No. 2 pillar (4b), which have no
connecting parts to minimize the weight and reduce the cost, and
then is connected to the front and rear corner parts on each side
of the bottom plate (3) and top plate (5).
[0047] The said No. 1 pillar (4a) and No. 2 pillar (4b) are formed
in bending in the
##STR00004##
shape in order to increase the durability. The cut parts (41', 42')
are formed to insert the top and bottom ends into the insertion
groove (33) of the bottom plate (3) and the insertion groove (52)
of the top plate (5), and many fixing grooves (41, 42) are formed
in an equal interval in the vertical direction to fix the display
frame (7) to many spots of an equal interval. In reference to FIG.
4, the said fixing groove (41) and fixing groove (42) are the spots
for insertion of fixing pins (72) to fix the display frame (7). The
said fixing groove (41) plays a role of preventing the display
frame (7) from being pushed to the front by opening the inside of
the cabinet (11) and closing the door (12) side, and the said
fixing groove (42) plays a role of preventing the display frame (7)
from being pushed to the front by opening the inside of the cabinet
(11) to form the hitch spot (42'') and closing the door (12) side.
In addition, the hitch spot (42'') of the said fixing groove (42)
prevents the display frame (7) from being pushed to the rear and
broken away. In addition, if the reinforcing angle (43) on the
bottom inner side of the No. 1 pillar (4a) and No. 2 pillar (4b) of
the pillar frame (4) is fixed by spot welding or the fixing bolt,
the reinforcing angle (43) is placed at the top of the bottom plate
(3), which increases the stability by dispersing the load
transmitted to the pillar frame (4) to the top of the bottom plate
(3), not concentrating it only to the fixing bolt.
[0048] The fixing member (6) fixes to the internal wall of the
cabinet (11) the top axis (61) inserted into the bushing (51)
installed on the top plate (5) and adjusts the perpendicular state
of the said pillar frame (4) while maintaining the center position
for rotation of the shelf structure (100). In other words, in order
to make a convenient adjustment of the perpendicular state of the
pillar frame (4), the fixing member (6) is composed of the fixing
plate (62), which fix the top axis (61), and a group of supports
(63) whose vertical part (63b) is fixed in contact with both walls
of the cabinet (11) while the horizontal part (63a) is fixed in
insertion into both ends of the said fixing plate (62). The long
hole drilled into the horizontal part (63a) of the said support
(63) compensates for the distance which varies depending on the gap
between both walls during tightening of the fixing bolts, and the
long hole drilled into the vertical part (63b) of the said support
(63) fixes the top axis (61) of the said support (63) on the wall
of the cabinet (11) while providing a upward/downward drift space
for its convenient insertion into the bushing (51) of the top plate
(5). Especially, it is desirable to compose the structure so that
the fixing plate (62) descends from the top side so that the upper
axis (61) be integrated to the bushing (51) as the imaginary line
shown in the FIG. 4 by forming the top part of the support (63) in
the open state so as to be convenient for inserting the fixing
plate (62) in the condition that the said support (63) is fixed to
the wall surface.
[0049] As shown in FIG. 1, the display frame (7) for display of
goods consists of the fixing plate (72), front frame (73), rear
frame (74), guide plate 975), support frame (76) and rear plate
(77), forming a polygon with the form of
##STR00005##
to display goods on the roller member (8'). The said fixing plate
(72) is combined in insertion into the fixing groove (41) of No. 1
pillar (4a) and the fixing groove (42) of No. 2 pillar (4b) for the
pillar frame (4). Both ends of the fixing plate (72) is combined at
an exposed state with the front frame (73) and the rear frame (74).
The said guide plate (75) is fixed to/combined with the front frame
(73) and the rear frame (74) while maintaining a certain gap with
them and forms the vertical wall (75) to prevent goods from
breaking away. The said support frame (76) is fixed to/combined
with the middle of the guide plate (75). The said rear plate (77)
is placed at the rear of the display frame (7) in the corner cut
form of a rectangular rear so that it may not contact the wall of
the cabinet (11) during rotation of the display frame (7). In order
to make the center of rotation inclined to the front without
contact of the corner of the front frame (73) with the wall of the
cabinet (11) during rotation of the display frame (7), the slope of
the said display frame fixed to the said rear frame is determined
by the height of the fixing groove (41) and the fixing groove (42)
formed at No. 1 pillar (4a) and No. 2 pillar (4b) of the pillar
frame (4) to which many display frames (7) may be installed, and
the slope ordinarily ranges from .angle.3 to 10.degree..
[0050] In order to reduce the weight of the said display frame (7)
and provide a smooth circulation of cooling air, the front frame
(73), rear frame (74), guide frame plate (75), and support frame
(76) are extrusion=molded with aluminum with a low specific
gravity. In order to increase the durability and reduce the weight,
as shown in FIGS. 7a and 7b, the part which the roller member (8')
is inserted into and the part which a series of rear plates (77)
are inserted into are opened, and other parts which the fixing
plate (72) is inserted into are formed in the form of a pipe.
[0051] And in the said display frame (7), as shown in FIG. 7b,
installed is the guide (81) to divide displayed goods. The use of
the roller member (8') which many rotating-type rollers (83) are
installed to enable division of each kind of goods and make the
first-in first-out arrangement easy for each kind of goods.
[0052] In addition, as shown in FIGS. 9a and 9b, the display frame
(7) of the present invention may be assembled of the front frame
(73), the rear frame (74), guide plate (75), support frame (76),
and roller member (8'), excluding the rear plate (77). In case the
said rear plate (77) is excluded, since the number of initially
displayed goods is identical, it is convenient to check the number
of sold items for each kind of goods.
[0053] In addition, in the present invention, as shown in FIG. 10,
as a method not to use the said fixing plate (72), it is possible
to compose the display frame (7) without using the rear frame (77)
by combining the hitch groove (752) drilled on the bottom surface
of the guide plate (75) of the said display frame (7), with the
bump (91) of clip (9) fixed to the fixing grooves (41, 42) formed
at No. 1 pillar 4a) and No. 2 pillar (4b) of the said pillar frame
(4).
[0054] The unexplained sign of 78 in the figures is a finishing
member inserted into the rear of ordinary roller members (8')
placed on the display frame (7), and 731 is a display part formed
as bump in the front frame (73) to insert goods names or price
tables.
[0055] Next, described are the installation and operation for the
rotating-type shelf structure of showcases in the present invention
made as explained above.
[0056] The base plate (2), fixing member (6), several display
frames for display of goods (7), bottom plate (3), pillar frame
(4), and top plate (5) are separately prepared and then mutually
combined to form the shelf structure (100) for installation inside
the cabinet of (11) of showcases (1).
[0057] First of all, the base plate (2) on which the bottom axis
(21) is installed is fixed on the floor of the cabinet (11) by
tightening screws, but as shown in FIGS. 3 and 4, the center of the
bottom axis (21) is set slightly in the floor front of the cabinet
(11), not the floor center. In other words, the center of rotation
is set so that the front and rear corner parts of the display frame
(7) may not contact the wall and door (12) of the cabinet (11)
during rotation of the display frame to be installed on the top of
the said bottom axis (21).
[0058] Next, the support (63) of the fixing member (6) is installed
beneath the ceiling part of the cabinet (11) responding to the
bottom axis (21) of the said base plate (2). The vertical part
(63b) of the support (63) for combination of both ends of the
fixing plate (62) is fixed on the wall of the cabinet (11) by
fixing bolts so that the top axis (61) may be located at the same
position of vertical direction as the bottom axis (21) of the base
plate (2) on which the support (63) of the said fixing member (6)
is installed. At this time, the fixing plate (72) on which the top
axis (61) is installed shall be on stand-by for post
installation.
[0059] Next, assembled is the rotating-type shelf structure (100)
rotating to display goods for sale by changing the front and rear
positions of the several display frames (7). The bottom plate (3),
pillar frame (4), and top plate (5) of the said shelf structure
(100) are mutually combined by fixing bolts, fixing nuts, and
tightening screws. On the said bottom plate (3), the bushing (31)
is fixed and ball castors (32) are installed around. On the top
plate (5), the bushing (51) is fixed. Assembling is completed by
tightening at the said basic assembling conditions with fixing
bolts and nuts the bottom plate (3) and top plate (5) to the top
and bottom parts of No. 1 pillar (4a) and No. 2 pillar (4b) of the
pillar frame which are composed in groups. For convenience of work,
the said nuts are already fixed through welding on the bottom plate
(3) and top plate (5).
[0060] In other words, in case the said bottom plate (3) and top
plate (5) are combined with No. 1 pillar (4a) and Np. 2 pillar (4b)
of the pillar frame (4), as shown in FIG. 5, the vertical parts of
the bottom plate (3) and top Plate (5) are inserted in line into
the cut parts (41', 42') of No. 1 pillar (4a) and No. 2 pillar
(4b), and No. 1 pillar (4a) and No. 2 pillar(4b) are inserted in
penetration into the insertion grooves (33, 52) drilled on the
bottom plate (3) and top Plate (5). Each corner part of the said
bottom plate (3) and top Plate (5) and each bended part of No. 1
pillar (4a) and No. 2 pillar (4b) are adhered, mutually combined,
and then tightened for a strong assembling by fixing bolts.
[0061] Next, the reinforcing angle (43) is fixed to the inner
bottom of No. 1 pillar (4a) and No. 2 pillar (4b) for the pillar
frame (4) by spot welding or fixing bolts, and the bottom of the
angle (43) contacts the top of the bottom plate (3) for
transmission of the load.
[0062] Next, when a frame is made by mutually combining the said
bottom plate (3), pillar frame (4) and top plate (4), the bushing
(31) fixed to the bottom plate (3) is first inserted in line into
the bottom axis (21) of the base plate (2) fixed on the floor of
the cabinet (1) to contact, as shown in FIG. 4, the ball castors
(32) fixed on the bottom plate (3) with the top of the base plate
(2) and position the bushing (51) fixed on the said top plate (5)
at the bottom of the fixing member (6).
[0063] In the above mentioned state, if the vertical part (63b) of
above said support materials (63) is integrated to the wall of the
cabinet (11) with fixing bolts after descending down the fixing
plate (62) of the fixing member (6) from the top side of the
support (61) of which the top part is opened as shown in the FIG. 4
so that the top axis (61) fixed to the fixing plate (62) can be
inserted to the bushing (51) of the top plate (5) to mutually be
integrated, and then fixing the fixing plate (51) to the horizontal
part (63a) of the support (63) with fixing bolts, the top axis (61)
will take a role of central axis of rotation of integrated bushing
(51).
[0064] The rotating-type shelf structure 100) integrated by
mutually combining the said bottom plate (3), pillar frame (4) and
top plate (4) rotates around the bottom axis (21) of the base plate
(2) and the top axis (61) of the fixing member (6). The rotation
gets smooth since the ball castor (32) installed on the bottom
plate (3) disperses the weight of the shelf structure and the
displayed goods.
[0065] Next, the guide plate (75) of the display frame (7) is
assembled at both ends by tightening screws to maintain a certain
gap with the extrusion-molded front frame (73), rear frame (74),
and support frame (76). The display frame unit (7) is assembled, as
shown in shown in FIG. 8, by installing the rear plate (77) to the
rear frame (74) and the roller member (8') to the top.
[0066] As a next step, if the both ends of the fixing pin (72)
inserted to the rear frame (74) are inserted into the fixing
grooves (42) which are formed on the second pillar (4b) and placed
on while the fixing pin (72) inserted to the front frame (73) of
the display frame (7) is being inserted to the fixing groove (41)
which is formed on the first pillar (4a) of the pillar frame (4) in
the condition that the fixing pin (72) is inserted to the front
frame (73) and the rear frame (74) of the unit display frame (7) as
described above , they are protected from being pushed to the rear
direction by the hitch spot (42'') and installed inclined in a
stable manner as shown in FIG. 4. Through above mentioned repeated
process, a multiple display frames (7) can be installed for
application with a certain intervals appropriate for withdrawal and
supplement of goods.
[0067] The rotating type shelf structure (100) assembled as explain
above rotates, as shown in FIG. 8, on the basis of the center of
rotation moved toward the door (12) rather than the floor center
while the corner-cut part located on the rear plate (77) of the
display frame (7) not contacting the wall of the cabinet (11). It
is possible to make an easy supplementation of sold goods from the
outside by positioning the said rotating display frame (7) to the
door (12).
[0068] For this reason, the rotating type shelf structure (100)
excludes the part connecting with the pillar frame (4) which forms
splitting into the first pillar (4a) and the second pillar (4b),
and reduction in weight enables smooth rotation and in turn,
reduction in the cost of raw materials. The said structure enables
to prevent twisting and deformation through mutual insertion
assembling of insertion grooves (33,52) which are formed on the
lower plate (3) and the upper plate (5) and cutting parts (41'',
42') which are formed on the first pillar (4a) and the second
pillar (4b). As the results, the durability can be maintained, and
the weight of display frame (7) comprising of various extruded
formed parts can be reduced, which enables the circulation of cool
air efficient and maintenance of freshness of goods. In addition,
opening the upper part of support (63) of the fixing member (6)
encourages the easy assembly and disassembly of the fixing plate
(62) and the barrier (22) which forms on the base plate (w)
prevents foreign materials or drinking water flowing into the ball
castors (32) and the bottom axis (21) to enable smooth rotation
always.
[0069] In addition, as shown in FIG. 9a, it may be possible to use
the display frame excluding the rear plate (77). In case the said
rear frame (77) is not available, since the number of
initially-displayed goods is unchanged, it is possible to check
fast the number of sold goods through the empty space created by
the sale or the number of left-overs.
[0070] In addition, as shown in FIG. 10, in the present invention,
it is possible to provide the convenience of fixing, hoisting, and
separating, excluding the rear plate (77), by combining the hitch
groove (75e) formed on the bottom of the guide plate (75) of the
display frame (7), with the bump of the clip (9) fixed in insertion
to the fixing grooves (41, 42) formed on No. 1 pillar (4a) and No.
2 pillar (4b) of the pillar frame (4)
[0071] As explained above, the desirable examples of the present
invention are described and shown by figures, but the present
invention is not limited only to what is described and shown by
figures. Therefore, since the persons in the field are well aware
of appropriate changes and modifications of the said examples, the
appropriate changes and modifications, and their equivalents should
be considered to belong to the scope of the present invention.
