Description
- The present invention relates to a display apparatus which is installed, for example, in a display chamber of vending machines and is capable of multiple display.
- It is desired that the display apparatus installed in the display chamber of vending machines change its advertising sign over time to provide effective advertisement of goods or to show a number of goods successively.
- A display apparatus currently available that meets the above requirements is disclosed in the Japanese Patent Preliminary Publication No. Showa 63-316293.
- In this display apparatus, a plurality of display plates are arranged in front of a fixed display board in such a manner that they are each pivotable 180 degrees about shafts provided at the upper and lower ends thereof. When the display plates rotate and stop at one rotation limit position, an advertising sign on the front surfaces of the display plates is shown. When the display plates rotate in the reverse direction and reach the opposite rotation limit position, another advertising sign on the back of the display plates is shown. When the display plates rotate halfway and stop at the middle between the two rotation limit positions, the display plates are directed parallel to the line of sight of a person looking at the display apparatus, so that the signboard behind the display apparatus can be seen through. Therefore, this display apparatus can show three kinds of advertising signs.
- This apparatus, however, has the following drawbacks.
- (1) When the display plates are directed almost parallel to the line of sight of a person looking at the display apparatus, the signboard or display board behind can be seen. But, since the display board is covered or masked to the extent of the thickness of the display plates, a clear vision of the display board is not obtained.
- (2) The signboard is covered at its front by the display plates and is fitted at the top with a support member that rotatably supports the shafts of the display plates. This construction makes it difficult to replace the signboard behind the display plates.
- A further example of the prior art is given in DE-A-2 044 028.
- This invention has been accomplished to eliminate the above-mentioned drawback and its objective is to provide a display apparatus in which each of the display plates is easy to see, in which a part of the display plates can be replaced with ease, and in which three or more advertising signs can be displayed, offering a multi-sign display capability.
- The above objective is achieved by a display apparatus according to this invention as disclosed in claim 1.
- Instead of using the stationary display board installed inside the circulating path of the drive member, the plurality of display plates may be divided into two groups and these groups of display plates be arranged on opposing regions of the drive member.
- The display apparatus of the above construction works as follows.
- As the endless drive member is driven, the plurality of display plates arranged on the specified region of the drive member are also driven. When the display plates are stopped in front of the stationary display board, the advertising sign on the front of the display plates are shown.
- Next, the drive member is driven again. When the display plates move past a first guide member located at one end of the circulating path of the drive member, they are not rotated but kept facing in the same direction. Thus, the display plates, after having passed the first guide member, enter the rear part of the circulating path of the drive member, with their front surfaces facing toward the inside of the circulating path. In this condition, the advertising sign on the stationary display board is shown.
- Further, when the display plates move past the other end of the circulating path of the drive member, they are rotated a half-turn by a second guide member so that the front surfaces of the display plates continue to face toward the inside of the circulating path. Therefore, when the display plates are stopped again in front of the stationary display board, the back surfaces of the display plates are shown. In this way, while the drive member is rotated a complete turn, three kinds of advertising signs are displayed.
- The stationary display board installed inside the drive member can easily be replaced from above as there is no obstruction hindering the upward movement of the board.
- In the display apparatus in which the stationary display board is eliminated and the plurality of display plates are divided into two groups that are arranged on two opposing regions of the drive member, since the two groups of display plates are alternately stopped in the front part of the circulating path for each half-turn of the drive member, four kinds of advertising signs are shown during one and a half turn of the drive member.
- Figures 1 through 6 represent embodiments of this invention; of which
- Figure 1 is a perspective view showing the outline of a display apparatus as a first embodiment of this invention;
- Figure 2 is an elevational view of a drive system that rotates a drive member;
- Figure 3 is a plan view showing the outline of the display apparatus;
- Figure 4 is a perspective view showing the display apparatus when display plates are moving past a first guide member;
- Figure 5 is a perspective view showing the display apparatus when display plates are moving past a second guide member; and

- Figure 1 is a perspective view showing the outline of a display apparatus; Figure 2 is an elevational view of a drive system that powers a drive member; and Figure 3 is a plan view showing the outline of the display apparatus.
- In Figure 2, an
output shaft 1a of a drive motor 1 is securely fitted with asprocket 2. Adrive shaft 4 which is supported at its ends by twobearings sprocket 5. Achain 6 is wound on thesprocket 2 and thesprocket 5. - The
drive shaft 4 has drivewheels 7 and 8 securely attached to the upper and lower parts thereof, thedrive wheels 7, 8 being formed as a sprocket. A drivenshaft 10 supported by twobearings drive shaft 4 and has drivenwheels wheels endless chain 13 is wound on and extended between the drive wheel 7 and the drivenwheel 11 and anotherendless chain 14 is wound on thedrive wheel 8 and the drivenwheel 12. - As the drive motor 1 rotates in the forward direction, the
drive shaft 4 is rotated in the direction of arrow R in Figure 3 causing adrive member 15 made up of twoendless chains - As shown in Figure 1, each of
display plates 18 is comprised of: apanel portion 16 formed of a rectangular plate material and having display surfaces at the front and the back to show advertising signs; andshaft portions 17 provided to the upper and lower ends of thepanel portion 16. - As shown in Figure 3, a
display window 19 is provided in front of thedrive member 15 and is attached with atransparent panel 20. Over a specified area of the drive member 15 (almost equal to the width of the display window 19), the twoendless chains drive member 15 are provided with a plurality ofsupport pieces 21 that project from the side thereof. Thesupport pieces 21 are each formed with a hole, in which theshaft portion 17 of eachdisplay plate 18 is rotatably supported. - In this specified area of the drive member 15 a plurality of
display plates 18 are arranged side by side with little gap. - The
shaft portion 17 has afirst projection 22 that projects almost perpendicular to thepanel portion 16 and asecond projection 23 that projects almost parallel to the panel portion 16 (see Figure 1). - A
first guide member 24 is provided on the left side of the circulating travel path of thedrive member 15. Thefirst guide member 24 consists of: afirst cam 25 that is located outside the circulating path of thedrive member 15 to guide thefirst projections 22 of theshaft portions 17; and asecond cam 26 that is located inside the circulating path of thedrive member 15 to guide thesecond projections 23 of theshaft portions 17. Since thefirst guide member 24 guides thefirst projections 22 and thesecond projections 23 in such a way as to prevent them from turning, thedisplay plates 18 are kept in the same attitude while passing the left end of the circulating path of thedrive member 15. - At the right end of the circulating path of the
drive member 15 there is provided asecond guide member 27. Thesecond guide member 27 consists of a disc-shaped cam installed inside the circulating path of thedrive member 15. Thesecond projection 23 is guided by thesecond guide member 27 to rotate a half turn, so that when thedisplay plate 18 moves past the right end of the circulating path of thedrive member 15, thedisplay plate 18 is swiveled to show the back of thepanel portion 16. - Inside the
drive member 15 is installed astationary display board 28. Thestationary display board 28 can be mounted and dismounted by making use of a space above thedrive member 15. - Now, the operation of the display apparatus of the above construction will be explained.
- As shown in Figures 1 and 3, when the
display plates 18 stop at the front part of the circulating path close to thetransparent panel 20, an advertising sign on the front of eachdisplay plate 18 can be seen through thetransparent panel 20. - Next, as the
drive member 15 is driven in the direction of arrow R, thedisplay plates 18 move past the left end of thedrive member 15. Since the first andsecond projections first guide member 24 as mentioned earlier, the front surface of eachdisplay plate 18 faces toward the inside of the drive member 15 (see Figure 4). - When all the
display plates 18 have passed the left end of thedrive member 15, thedrive member 15 is stopped. Now, an advertising sign on thestationary display board 28 can be seen through thetransparent panel 20. - Then, the
drive member 15 is again driven in the direction of arrow R. When thedisplay plates 18 pass the right end of thedrive member 15, each of thesecond projections 23 is guided by thesecond guide member 27 to rotate a half turn, so that when thedisplay plates 18 stop at the front part of the circulating path close to thetransparent panel 20, another advertising sign at the back of thedisplay panels 18 can be seen through thetransparent panel 20. - In this way, three kinds of advertising signs are displayed successively over time. Because the
stationary display board 28 can easily be dismounted, the advertising effect can be enhanced by replacing, as required, the existingdisplay board 28 with anotherboard 28 having a desired advertising sign. - Figure 6 is a plan view showing the outline of a second embodiment of this invention, in which two groups of
display plates 18 are mounted on two opposing regions of thedrive member 15, with thestationary display board 28 removed. In other respects, this second embodiment is similar to the first embodiment. - In Figure 6, let the front and back of each
display plate 18 of the first group located at the front part of the circulating path be designated a and b. Also let the front and back of eachdisplay plate 18 of the second group located at the rear part of the circulating path be designated c and d. Each time thedrive member 15 is driven half-turn in the direction of arrow R and stopped, the advertising sign shown on the display apparatus changes from one of the four kinds of advertising signs (on the front a of the first group ofdisplay plates 18, on the front c of the second group, on the back b of the first group and on the back d of the second group) to the next, thus showing a variety of advertising signs over time. This enhances the effect of advertisement. - With the above-mentioned construction, this invention offers the following advantages.
- (1) Since there is no obstruction in front of the display plates, a clear view of the advertising sign is obtained.
- (2) The display apparatus has a structure that allow easy replacement of the stationary display board, which in turn permits multiple advertising signs to be displayed.
- (3) When two groups of display plates are attached to the opposing regions of the drive member, four kinds of advertising signs can be displayed.
- These advantages all contribute to enhancing the advertising effect.
