Ribbon display rack

Abstract

A ribbon display rack includes a frame unit, a tilting seat, and a plurality of partitions. The frame unit includes a base plate, a back plate disposed above the base plate, two side plates spaced apart above the base plate, and a stop disposed above the base plate and in front of the back plate. The tilting seat is disposed on the base plate and between the back plate and the stop. The tilting seat includes an inclined surface that slopes forward and toward the base plate in an inclined direction. The partitions are spaced apart on the inclined surface in a left-right direction. The height of each partition relative to the inclined surface gradually increases forward in the inclined direction. The side plates and the partitions together define a plurality of grooves. The front height of each partition is higher than its rear height, which prevents the ribbon from rolling out of the original groove when it reaches the bottom.

Description

Technical Field

[0001] The present invention relates to a display stand for displaying ribbons, in particular to a ribbon display stand. Prior Art

[0002] An improved ribbon rack structure, such as that disclosed in Republic of China Announcement No. M374302, comprises a lower frame, a bottom plate, and an upper frame. The lower frame is a rectangular frame, with support plates mounted on each of its four corners. Side panels are mounted on both sides of the frame, and a support plate is mounted on the rear end. The bottom plate is mounted within the lower frame. Several positioning grooves are formed in the plate, and several partitions are mounted on each of them, forming sliding grooves between the partitions. Two long sides, running in the same direction as the partitions, are each provided with a frame. The upper frame is mounted on the upper end of the top plate of the lower frame.

[0003] However, when multiple ribbon rolls are placed in the sliding troughs, they may become offset or push against the partitions on either side, generating friction that hinders the ribbon's rolling. Furthermore, the contact area between the ribbons and the partitions increases exponentially with the number of ribbons. Placing more ribbon rolls increases friction, which can easily lead to problems with smooth ribbon rolling. Summary of the Invention

[0004] Therefore, the object of the present invention is to provide a ribbon display stand that can improve at least one of the above-mentioned shortcomings.

[0005] Therefore, the ribbon display stand of the present invention includes a frame unit, a tilting seat, and a plurality of partitions. The frame unit includes a bottom plate, a back plate disposed above the bottom plate along a vertical direction, two side plates disposed above the bottom plate at intervals along a left-right direction perpendicular to the vertical direction, and a stopper disposed above the bottom plate and located in front of the back plate along a front-to-back direction perpendicular to the vertical and left-right directions. The tilting seat is disposed on the bottom plate and located between the back plate and the stopper. The tilting seat includes an inclined surface that is inclined forward and toward the bottom plate along an inclined direction perpendicular to the left-right direction. The partitions are disposed on the inclined surface at intervals along the left-right direction. The height of each partition increases gradually toward the front of the inclined surface along the inclined direction. The side plates and the partitions together define a plurality of slide slots.

[0006] The present invention's effectiveness lies in the fact that the height of the partitions gradually increases forward along the inclined surface, causing the contact area between the ribbons and the two partitions on either side to gradually decrease from bottom to top along the inclined surface. Compared to conventional partitions designed with equal height, when the front height of the conventional partitions is the same as that of the present invention, the total contact area between the ribbons and the two partitions, and the resulting friction, is smaller. Therefore, when the front ribbon is removed, the rear ribbons can roll smoothly. Furthermore, the ribbons can be prevented from rolling out of the original chute due to inertia when they come to a stop. Simple diagram description

Implementation Method

[0008] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0009] 1 and 2 , an embodiment of a ribbon display stand of the present invention includes a frame unit 1 , an inclined seat 2 , a plurality of partitions 3 , two cushions 5 , and a connecting unit 6 .

[0010] The frame unit 1 includes a base plate 11, a back plate 12 connected to the top of the base plate 11 along an up-down direction Z, two side plates 13 connected to the top of the base plate 11 at intervals along a left-right direction Y perpendicular to the up-down direction Z, a horizontal plate 14 connected between the top ends of the side plates 13 and adjacent to the front side, two support members 15 respectively arranged between the side plates 13 and the horizontal plate 14, and a stopper 16 connected to the top of the base plate 11 and located in front of the back plate 12 along a front-back direction X perpendicular to the left-right direction Y and the up-down direction Z.

[0011] Referring to Figures 2 to 4 , the back panel 12 is connected between the side panels 13. The bottom panel 11, back panel 12, and side panels 13 are each composed of two stacked AB corrugated sheets 17. The fluting direction of the bottom panel 11 extends along the left-right direction Y, while the fluting direction of the back panel 12 and side panels 13 extends along the up-down direction Z. Note that since the cross-section of the back panel 12 is identical to that of any of the side panels 13, the cross-section of the back panel 12 is omitted in Figure 2 .

[0012] 5 , each of the support members 15 is L-shaped and disposed between the inner side surface of the corresponding side panel 13 and the lower side surface of the transverse panel 14 to enhance the structural strength between the transverse panel 14 and the side panels 13 .

[0013] 2 and 3 , the stopper 16 is stepped and connected between the side panels 13. The stopper 16 has a first step 161 extending upward from the bottom panel 11, and a second step 162 connected to the front side of the first step 161 and higher than the first step 161.

[0014] 6 and 7 , the tilting base 2 is placed on the bottom plate 11 and located between the back plate 12 and the stopper 16 . The tilting base 2 includes two cardboard holders 21 arranged side by side along the left-right direction Y. Each cardboard holder 21 has a plate body 22 and two ribs 23 .

[0015] For ease of explanation, the following describes the structure of the cardboard holder 21 as an example. The plate 22 comprises a central portion 221 and two side portions 222 connected to opposite sides of the central portion 221 along the left-right direction Y. The central portion 221 is formed with a plurality of insertion holes 223. Each side portion 222 is formed with three slots 224 spaced apart along the front-to-back direction X. The side portions 222 are bent downward and inward, forming the plate 22 into a wedge shape. The ribs 23 are inserted upward into the corresponding slots 224 to secure the shape of the plate 22.

[0016] 3 and 6 , the top surfaces of the cardboard holders 21 collectively define an inclined surface 24. The inclined surface 24 is inclined forward and toward the bottom plate 11 along an inclined direction A perpendicular to the left-right direction Y. The insertion holes 223 are arranged in an array on the inclined surface 24 along the left-right direction Y and the inclined direction A.

[0017] 2 and 3 , the front end of the tilting seat 2 is spaced from the stopper 16 and defines together with the stopper 16 a transverse groove 18 extending along the left-right direction Y. Specifically, the width of the transverse groove 18 along the front-back direction X is 6 cm.

[0018] Referring to Figures 3, 5, and 6, the partitions 3 extend along the inclined direction A and are spaced apart along the left-right direction Y on the inclined surface 24. The height of each partition 3 relative to the inclined surface 24 gradually increases forward along the inclined direction A. The side panels 13 and the partitions 3 together define a plurality of chute slots 4. Each partition 3 has a bottom surface 31, a top surface 32, a front surface 33, a rear surface 34, and a plurality of spaced-apart inserting portions 35 extending downward from the bottom surface 31.

[0019] The front end of the bottom end surface 31 protrudes forward relative to the front end of the top end surface 32. The front end surface 33 extends from the front end of the bottom end surface 31 to the front end of the top end surface 32 and has a convex arc shape. A front height d1 is defined between the top end of the front end surface 33 and the inclined surface 24. The rear end surface 34 extends from the rear end of the bottom end surface 31 in a direction perpendicular to the inclined direction A to the rear end of the top end surface 32. A rear height d2 is defined between the top end of the rear end surface 34 and the inclined surface 24. The insertion portions 35 of each partition 3 are inserted into the corresponding insertion holes 223 to be fixed to the inclined surface 24.

[0020] Referring to Figures 3, 5, and 6, the cushions 5 are projecting from opposite sides of the inclined surface 24 along the left-right direction Y and extend along the inclined direction A. The height of each cushion 5 relative to the inclined surface 24 is lower than the height of each partition 3 relative to the inclined surface 24. Specifically, each cushion 5 is slightly higher than the inclined surface 24, has a thickness of 2 mm, and a width of 1.5 cm.

[0021] Referring to Figures 2, 5, and 6, the connection unit 6 includes four top connectors 61 disposed on the top surfaces of the side panels 13, four bottom connectors 62 disposed on the bottom surfaces of the side panels 13 and positioned corresponding to the top connectors 61, two first connectors 63 disposed on the top outer side of one of the side panels 13, and two second connectors 64 disposed on the outer side of the other side panel 13 and positioned corresponding to the first connectors 63. Each bottom connector 62 is used to connect to the top connector 61 of another ribbon display stand. Each first connector 63 is used to connect to the second connector 64 of another ribbon display stand. Specifically, a Velcro structure is used between each top connector 61 and the corresponding bottom connector 62, or between each first connector 63 and the corresponding second connector 64.

[0022] Referring to Figures 5 and 8 , the ribbon display stand can accommodate and display multiple rolls of ribbon 7, with each chute 4 capable of accommodating six rolls of ribbon 7. Each roll of ribbon 7 includes a reel 71 and a ribbon body 72 wound around the reel 71. The width of the ribbon 7 can be 1.5 inches (approximately 3.81 cm), 2.5 inches (approximately 6.35 cm), or 5 inches (approximately 12.7 cm). In this embodiment, there are eight chute 4s, three of which are 5 cm wide and five of which are 8 cm wide. The chute 4s of different widths are arranged in an alternating pattern. In other variations of this embodiment, the number, width, and arrangement of the chute 4s can be adjusted as needed. It should be noted that although the width of each chute 4 is slightly larger than the width of the ribbons 7 inside, the ribbons 7 will press against the two partitions 3 on both sides due to position offset or mutual pushing, thereby generating friction.

[0023] The effects and advantages of using the ribbon display stand of the present invention to display the ribbons 7 are described below.

[0024] Referring to Figures 2 and 3 , when a consumer removes the frontmost ribbon 7 for viewing, the ribbons 7 behind it roll down and rest against the stopper 16, saving staff time in rearranging them. Furthermore, after viewing, the user can return the ribbon 7 to its original chute 4. Because the front end surface 33 of each partition 3 is convexly curved, this prevents the returning ribbon 7 or the side of the pushed ribbon 7 from being pressed against the front end surface 33 and causing damage (compared to a structure where the front end surface 33 and the top end surface 32 are at right angles). In one embodiment, if each roll of ribbon 7 is also wrapped with a transparent shrink film (not shown), this also prevents damage to the shrink film. This reduces the processing costs of product returns or exchanges, ensures that the product is sold in pristine condition, and enhances product quality confidence.

[0025] The corrugations of the bottom panel 11 extend along the left-right direction Y, enhancing the strength of the ribbon display racks when placed side by side. The corrugations of the back panel 12 and side panels 13 extend along the up-down direction Z, enhancing the support strength of the ribbon display racks when stacked. The ribbon display rack is entirely made of cardboard, offering a simple structure and light weight, making it easy to assemble and transport.

[0026] The ribbons 7 roll along the inclined direction A. Therefore, it can be understood that the height of the partitions 3 relative to the inclined surface 24 gradually increases along the rolling direction of the ribbons 7, thereby preventing the ribbons 7 from running out of the corresponding chute 4 due to inertia when rolling to a stop, thereby enhancing the limiting effect.

[0027] Because the majority of the front ribbon 7 lies outside the chute 4, its contact area with the two partitions 3 on either side is relatively small. The contact area between the remaining ribbons 7 and the two partitions 3 on either side gradually decreases from bottom to top along the inclined surface 24. Compared to conventional partitions designed with equal heights, when the front height d1 of the conventional partitions is the same as the front height d1 of the partitions 3 in this embodiment, the total contact area and friction generated by the ribbons 7 on either side of the partitions 3 in this embodiment is relatively small, resulting in smoother rolling of the ribbons 7.

[0028] The combination of the first step 161 and the second step 162 increases the thickness of the stopper 16 along the front-to-back direction X, thereby enhancing the structural strength of the stopper 16 and preventing deformation caused by the long-term compression of the ribbons 7. The first step 161 of the stopper 16 and the front end of the tilting seat 2 jointly support the frontmost ribbon 7, and the frontmost portion of the ribbon 7 is accommodated in the transverse groove 18, maintaining a stable position and preventing it from shaking. When the frontmost ribbon 7 is removed, the rear ribbon 7 rolls into the transverse groove 18, and the second step 162 further blocks the ribbon 7, preventing it from rolling over the stopper 16 due to inertia or compression by the remaining ribbons 7.

[0029] 5 , each pad 5 can raise the outer side of the corresponding ribbon 7 and tilt the ribbon 7 slightly inward to prevent the ribbon 7 from abutting against the corresponding side panel 13 , thereby reducing the friction between the ribbon 7 and the side panel 13 and allowing for smooth rolling.

[0030] Refer to Figure 9, which illustrates an embodiment of stacking and juxtaposing multiple ribbon display racks. In this embodiment, corresponding top connectors 61 connect to corresponding bottom connectors 62, and corresponding first connectors 63 connect to corresponding second connectors 64, thereby displaying a large number of ribbons 7 of varying styles and widths. Note that the outermost portions of the ribbon display racks along the juxtaposition direction are not provided with the first connectors 63 and the second connectors 64 to maintain aesthetic appeal. Furthermore, when the ribbon display racks are stacked on a pallet (not shown), a forklift can be inserted into the pallet to quickly move a large number of ribbons 7.

[0031] Referring to Figure 3 , when the frame unit 1 is positioned horizontally, the inclined surface 24 defines an inclination angle θ1 with the horizontal plane in a cross-section perpendicular to the left-right direction Y. The top surface 32 of each partition 3 defines a straight reference line S. Each reference line S and the inclined surface 24 define an expansion angle θ2. The ranges of the inclination angle θ1 and the expansion angle θ2 are defined as follows.

[0032] The dimensions of the ribbon display stand are determined by the size and quantity of the ribbons 7 required to be accommodated. To allow the front ribbons 7 to be removed when the ribbon display stand is stacked, the distance between the top of the frame unit 1 and the top of the stopper 16 must be greater than the diameter D of each ribbon 7. Specifically, the distance between the top of the frame unit 1 and the top of the stopper 16 is approximately 1.3D, and the height H1 between the top of the frame unit 1 and the top of the base plate 11 is approximately 1.5D. Furthermore, the length L of the inclined surface 24 along the inclined direction A is approximately 6D, and the height H2 between the top of the inclined surface 24 and the top surface of the base plate 11 is approximately 6D sin θ1.

[0033] To effectively utilize the space within the frame unit 1, the height H3 between the top of the frame unit 1 and the top of the inclined surface 24 must be slightly greater than the diameter D of the ribbon 7. If this height H3 is too large, the usable space of the frame unit 1 along the vertical direction Z will be wasted. If this height H3 is too small, when the ribbon display racks are stacked and the chutes 4 are filled with ribbons 7, the rearmost ribbon 7 may become stuck on the upper ribbon display rack, and the front ribbon 7 may become stuck on the horizontal plate 14. Therefore, based on the aforementioned constraints, the range of the tilt angle θ1 can be estimated as follows.

[0034] D <H3。

[0035] D

[0036] D<1.5D-6D.sinθ1.

[0037] sinθ1<0.5 / 6.

[0038] θ1 <sin -1(0.5 / 6)≒4.78°。

[0039] In one embodiment, the tilt angle θ1 ranges from 1° to 4°. Specifically, the tilt angle θ1 is 3°, which allows the inclined surface 24 to maintain an optimal tilt angle, allowing the ribbons 7 to roll smoothly and preventing the rear ribbon 7 from being too high and pressing against the ribbon display stand above.

[0040] The dimensions of the partitions 3 and the definition of the expansion angle θ2 are described below.

[0041] ​To prevent the ribbon 7 at the rear end of the chute 4 from tipping over, the rear side height d2 of each partition 3 must be greater than or equal to 0.1D. Specifically, to prevent the rear side height d2 from being too high and causing increased friction, the rear side height d2 is 0.1D.

[0042] To ensure the front end of the partition 3 effectively holds the ribbon 7 in place and prevent excessive friction from affecting its rolling motion, the front height d1 of each partition 3 must be greater than one-fifth of the diameter D and less than one-half of the diameter D. Therefore, the front height d1 is greater than 0.2D and less than 0.5D, and is approximately equal to L.tanθ2+d2. Therefore, the range of the divergence angle θ2 can be calculated as follows.

[0043] 0.2D<6D.tanθ2+0.1D<0.5D.

[0044] 0.1<6.tanθ2<0.4.

[0045] 0.1 / 6 <tanθ2<0.4 / 6。

[0046] 0.95°≒tan -1(0.1 / 6)<θ2 <tan-1(0.4 / 6)≒3.8°。

[0047] In one embodiment, each expansion angle θ2 is in the range of 1° to 3°. Specifically, each expansion angle θ2 is 2°, so that the partitions 3 can stably position the ribbons 7 and maintain smooth rolling of the ribbons 7, and prevent the ribbons 7 from running out of the chute 4 when rolling to the bottom.

[0048] In summary, the height of the partitions 3 of the ribbon display stand of the present invention increases gradually forward along the inclined direction relative to the inclined surface 24, causing the contact area between the ribbons 7 and the two partitions 3 on either side to gradually decrease from bottom to top along the inclined surface 24. Compared to the prior art design of partitions of equal height, when the front side height of the prior art partitions is the same as the front side height d1 of the partitions 3 of the present invention, the total contact area between the ribbons 7 and the two partitions 3 on either side, and the resulting friction, is smaller. When the ribbon 7 at the front is removed, the ribbons 7 at the rear can roll smoothly. Furthermore, the ribbons 7 are prevented from rolling out of the original chute 4 due to inertia when they stop, resulting in an effective limiting effect, thus effectively achieving the purpose of the present invention.

[0049] However, the above is merely an embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application and the content of the patent specification of the present invention are still within the scope of the patent of the present invention.
