The storage of digital video disk and display rack

Technical field

The present invention relates generally to the display rack that is used for keeping article, and these article comprise for example digital video disk (DVD), DVD box and other similar products.

Background technology

It is well-known taking the DVD display rack that does not have moving component of vertical shape tower or horizontal cabinet form.But in the time of in a large amount of DVD is stored in this tower or cabinet, displaying and select required DVD, when required DVD is stored in the bottom of vertical tower, will be very difficult particularly.

Applicant's basic patent discloses a kind of electronic CD dish storage device or display rack, and this device can store many CD or its congener in a rotating display rack, and this CD is rotated, till this required CD occurs.When required CD occurs, can make to rotate to stop and required CD is taken out from display rack.

Although the display rack of the disclosure can store a large amount of CD or other article, and use and to have obtained very ten-strike,, exist needs at present for the display rack that can store DVD.In addition, because DVD usually uses, just need a kind of DVD display rack that can illuminate the DVD that keeps by it, in the environment with weak surround lighting so that in this environment, select DVD.This easy to use in order to promote, need be by this display rack of friction speed and different directions handle to(for) hand operation and/or pin for example be provided, and the selective power that stops and working.Because the cause of stability, the expansion of the storage volume of display rack need bigger base usually.But the expansion of base just needs bigger being used for to load and transport the carton of these display racks, will increase the commercial value of this product on market thus.Therefore, just need base device to provide necessary stability, also do not need bigger packaging carton for display rack.In addition, after scan code had been discerned DVD or other maintained article, perhaps after the user sent verbal order, this display rack also should provide the selective power that automatically stops operating.At last, this display rack preferably has the ability of carrying out the daisy chain ring with other this class display rack.

Different with the CD box, the DVD box is made into two kinds of different structures usually.First kind of common DVD box structure is Amaray Safe Box.Amaray Safe Box is a box that is of a size of 7.52 inches * 5.35 inches * 0.6 inch, and this box has a push button locking hub of being convenient to unclamp dish, and the clamper that is used for the multipage catalogue.Second kind of common DVD box structure is commonly referred to Snapper Box, and this box and Amaray Safe Box are similar, but it is of a size of 7.47 inches * 5.58 inches * 0.53 inch.Be used for keeping the electronic display rack of DVD box preferably should two kinds of DVD sizes can both store.In addition, because being used for the size of the retainer of DVD box must be greater than the size of the retainer that is used for the CD box, preferably come carrying to have the display rack of this retainer, cost and the trucking costs that can save the container that this display rack is housed thus with a kind of compact size.The invention provides this display rack.

Summary of the invention

In a preferred embodiment of the invention, the storage volume in display rack increases by the loop that forms a rotation or the interconnected retainer of endless belt are provided.In one embodiment of the invention, each retainer keeps at least one article with different size, for example DVD casket or box.In another embodiment of the present invention, the display rack of endless belt more than comprises by interconnected retainer and being connected to each other and the endless belt that is provided with abreast that forms that each retainer keeps article.In yet another embodiment, each retainer can keep at least two such article with structure side by side.Therefore, produce a kind of single endless belt of interconnected retainer, maintained more than one article in each retainer in this band.In these embodiments, when rotated the endless belt, the user can see maintained article, and needed when being held article when seeing, the user just can make the endless belt rotate to stop.The upper area that rotates in the endless belt, the zone that maintained article will scatter by a fan-shaped can especially easily be taken out article in this zone from the endless belt that this stops, for example caught the back to take out by user's finger.

Each retainer embodiment preferably includes first and second walls or finger piece, and they remain on the position of spaced-apart certain distance, and this distance is enough to hold and keep at least a portion of at least one such article.In order to improve maintenance, the surface in the face of retainer of a finger piece in this wall or the finger piece spreads all over the whole width of DVD box, and comprises that prevention DVD box skids off the keeper that comes from retainer.In other embodiments, this keeper is meshed with this finger piece so slidably, makes it to be adjusted to upper position or lower position, perhaps adjusts to the specific width place of DVD.It will be about twice of the width of Individual Items retainer that its size can keep the width of the retainer of two article.The retainer of two article can comprise a next door or finger piece, separates with at least a portion of the apparent surface that will remain on two article in the retainer.

Each retainer also comprises at least one positive type (or claiming first type) coupling arrangement or connector, and at least one cloudy type (or claiming second type) coupling arrangement or connector.These devices form like this, make the positive type coupling arrangement on first retainer and the cloudy type coupling arrangement of adjacent second retainer be connected to each other, and the positive type coupling arrangement of cloudy type coupling arrangement on first retainer and adjacent the 3rd retainer is connected to each other.Be connected to each other and the endless belt of the rotation that forms can change by increasing or reduce (i.e. dismounting) retainer by this retainer (in this endless belt length it can be said to be standard package).Each retainer is preferably integrally made as single part.

The loop of this rotation or endless belt preferably are configured in the display rack, and this display rack comprises a left side and the right vertical support that remains on the base element.The embodiment of the display rack that the endless belt that separates (that is two endless belts) that is formed by interconnected Individual Items retainer is formed can comprise that is positioned at two the 3rd vertical support in the middle of the Individual Items retainer that is provided with abreast.Though this loop or endless belt can be rotated with artificial, for example use a wind or with hand retainer is rotated simply,, had better use motor to come driven rotary.In one embodiment, a sprocket rotation axle is arranged, and a sprocket rotation axle is arranged near this bottom fan-shaped (or turning to) annular region of scattering near this top fan-shaped (or turning to) annular region of scattering.But, these two or more parallel sprocket rotation axles can by be arranged on one or two fan-shaped scatter in the zone replace.In addition, also it is contemplated that the axle that only not be used in the bottom with a sprocket rotation axle.

This motor is by (for example being installed in this base element) powered battery, perhaps by an external power source.One or morely can control loop rotation direction and the speed that forms by interconnected retainer by the control device that the user handles.Such control device can be arranged on the supporting member in the vertical support, so that the user takes with hand.In addition, or another way or additionally, the control device of equivalence can be arranged on the base element, so that used by user's pin.

Base element preferably has and can after this side direction base element has been installed, just can enlarge effective areal coverage of whole understructure by the side direction base element of user installation, has increased the stability of display rack thus.But, when display rack is loaded and transported by manufacturer, this side direction base element can be unloaded, so just can in a less and more cheap packaging carton, load and transport.In another embodiment, each retainer comprises an adjustable maintenance tab, and when transportation, it is pushed into its minimum height, so that make the size of packaging carton reduce to minimum.

This display rack comprise one optional for example by light emitting diode and the lighting device that diffuser is formed of several whites.This lighting device can be arranged on fan-shaped and scatter near the zone, is preferably disposed on the top of a side direction vertical member in the side direction vertical member.Behind electrical power, this light source just illuminates the article that kept by retainer, so that observe and select, and after motor is stopped operating by the user, this light source can also continue to throw light on a period of time (for example about a minute).This lighting device can randomly be provided with a photoscanner, and this scanner scans is attached to the bar code on the article that kept by display rack and the content of article discerned.An optional telechiric device can be handled by the user, when going out the required bar code of user with convenient scanner recognition, can order the electronic installation that interrelates with display rack to stop loop rotation, this required bar code preferably by user's remote control pass to electronic installation.If desired, scanister can increase a speech recognition system, and when the article by user speech identification are gone out by this scanner recognition, this system just will stop loop rotation.Another way is, if thereby this display rack of user's close enough can directly be seen required article, just can use verbal order to stop the rotation of display rack, so that the user takes out required article from display rack.Display rack can carry out the daisy chain ring with one or more other display racks, makes display rack of user command rotate the endless belt that will make in all display racks and rotates.

Embodiment

Fig. 1-2 shows first embodiment of tower shape display rack 10 of the present invention, and this display rack can store a plurality of containers 18 (for example the DVD box is seen Figure 13) of the DVD that for example is included on the conveyer.Display rack 10 (also can be described as tower 10) is a kind of device that is used for keeping reaching 100 (in a preferred embodiment) or more DVD in its container.Display rack 10 comprises a plurality of retainers 32, and these retainers are connected to each other and form an endless belt 23 (also can be described as loop 23) together.As back in this article is illustrated, be with what a plurality of retainers 32 linked together 23 can drive by motor 28 (see figure 4)s.

The suitable control device (for example button 37, see Fig. 3) that is connected with an electric switch (not shown) can be used for connecting motor 28 (Fig. 4), so that the DC voltage of one first polarity of (1) effect; (2) DC voltage of second an opposite polarity of effect; (3) effect can be adjusted the voltage of two polarity of size; Perhaps (4) do not have the DC voltage effect fully.Band or loop 23 (are for example rotated clockwise or counterclockwise, as using the direction shown in the arrow 20 among Fig. 3), can adjust the velocity of rotation (for example from high to low) of motor, perhaps can be by operating voltage and motor 28 are disconnected all motions that stop with 23.As shown in Figure 3, control device 37 can so that endless belt 23 is clockwise rotated, perhaps rotate along inhour, so that endless belt 23 is rotated along counter-clockwise direction along clockwise rotating.In one embodiment, control device is along rotating manyly more on any direction, and the magnitude of voltage that acts on the motor 28 is just more little, and endless belt 23 rotation in a predetermined direction is just slow more.On the contrary, in another embodiment, control device is many more along the rotation on the predetermined direction of endless belt, and band or the rotation of loop 23 on this direction are just fast more.Control device 37 makes the user that this band is rotated, till required article (normally being encapsulated in the DVD in the container 18) arrive the upper zone 11 of display rack 10.In upper zone 11 (and in foot district), retainer 32 (making container 18 thus) becomes fan-shaped to scatter, and facilitates personnel selection handgrip container 18 like this and takes out from display rack 10.Usually, in vertical zone 13, container 18 holding position between mutually is close like this, so that they is taken out from retainer will compare difficulty.But, occur in the one-tenth fan-shaped that turns in the district 11 (also can be described as fan-shaped the scatter district 11) work that will make the user from display rack 10, take out required article 18 of scattering and become easily.

Display rack 10, for example at Fig. 1, shown in 2,13 and 14 like that, it can make by a plurality of retainers 32 that only the keep Individual Items 18 formed endless belt 23 that links together and rotate, and is also referred to as single annular band display rack in this article.As will being described in detail below (for example with reference to Figure 16 B), some embodiment of the present invention has a plurality of endless belts.

As shown in Figure 1, preferably be located vertically between a pair of opposed

vertical support

14 and 16 that separates at a certain distance each other by link together formed endless belt or loop 23 of a plurality of retainers 32, these supporting members remain on the display rack base 12.A kind ofly be used for replacing the mounting structure of structure shown in Fig. 1 can comprise the additional endless belt 23 of rotating with respect to a vertical stratification (for example wall).Though the preferred embodiment will be rotated according to motor-driven endless belt and will be described,, motor 28 can be replaced (perhaps increasing a wind) by a wind, and the user can rotate this wind rotates endless belt or loop.These different structures preferably by a kind of cheap, make by lightweight material, ABS plastic for example, but other materials also can use.

Referring to Fig. 3, drive

sprocket

36,38 rotates on axle 40, and this axle uses journal rest between vertical support 14 and 16.Axle 40 and

sprocket wheel

36,38 all are configured in the top of display rack or tower 10, and for example by utilizing control device 37 (see figure 1)s by motor 28 (see figure 4) driven rotary.The details of this drive system further is provided among Fig. 4.In one embodiment of the invention, motor 28 utilizes the following

drive sprocket

22,24 that pulley apparatus 30 drives on axle 26.Motor 28 shown in the figure,

sprocket wheel

22 and 24, and belt pulley 30 all is configured near the base 12 of display rack 10, reduced the center of gravity of display rack 10 thus.Another kind of way is, motor 28 is placed near the top of display rack 10 on (for example in the shown position of the embodiment of Figure 16 B).Even have only a upper sprocket wheel can use the middle position of axle 40 (for example), use this to provide the driving of balance more to the endless belt 23 that

sprocket wheel

36 and 38 still can form being connected to each other by a plurality of retainers 32.In order to guarantee the enough tension force in this endless belt, can use the bearing seat installation shaft 40 (and/or axle 26) of pad effect.Another way is that motor 28 (and pulley apparatus 30) can drive

upper sprocket wheel

36,38, rather than lower sprocket 22,24.In a kind of like this structure,

lower sprocket

22,24 can randomly be cancelled, and the fan-shaped district of scattering in bottom can hang, rather than around sprocket engagement.This suspension can guarantee enough tension force in endless belt 23.

Referring to Fig. 3 and 4, vertical

lateral supports

14 and 16 preferably includes

guide rail

44 and 46, so that with go up slidably interlock 47 (Fig. 6) cooperation that forms in the bottom surface 27 (it is towards display rack 10 inside) of each retainer 32, guide effectively and keep endless belt 23.As seeing in Fig. 6 and 9, according to one embodiment of present invention, interlock 47 is such L type shape, makes them to be meshed with

guide rail

44 and 46, and slides along this guide rail.These parts help altogether to vertically upward or the retainer 32 of downward slip carry out clamping.As shown in Figure 3,

guide rail

44 and 46 stops (and also under stop before turning to the district) before the district 11 last turning to, so that endless belt 23 can embayment curved (for example passing through to center on sprocket rotation).

Article or container 18 are releasably kept by the elastic connector of retainer 32, as reference Fig. 5-10 is illustrated, illustrate in greater detail the retainer 32 with different orientation among these figure.Each retainer 32 comprises a base 33, and a pair of isolated at a certain distance mutually

finger piece

34 and 35 stretches out from this base, and in the groove shape space that this distance is enough to form between finger piece at least one marginal portion of storage container 18.

Finger piece

34 and 35 holds the edge (or side) on opposed (for example left side and right) of the DVD box that is inserted in the groove shape space that forms between the finger piece or container.As mentioned above, the DVD box has two kinds of common structures.For the DVD that guarantees two kinds of sizes can be assembled in the retainer 32, the spacing distance of the finger piece 34 of each

retainer

32 and 35 opposed faces is about 7.6 inches.

These

finger pieces

34 and 35 have promoted the installation and the maintenance of DVD box 18, and before the user selected and takes out from retainer 32, this box all was maintained.As shown in Fig. 5-9, each retainer 32 comprises a short finger piece 34 and a long finger piece 35.In a preferred embodiment, when DVD box 18 inserted in the retainers 32, short 34 of finger pieces were crossed the about 1/3rd of going up of this box or lower surface, long finger piece 35 then cross this box counter surface about 3/4ths.Should be pointed out that

finger piece

34 and 35 crosses various other length on the surface of box 18 and stretch out also and belong in the spirit and scope of the present

invention.Finger piece

34 and 35 is parallel to each other basically, so that consistent with the shape of DVD box 18.

Each retainer 32 comprises a keeper 52 that stretches out from finger piece 35.Keeper 52 comprises a platform 54, and this platform has the first maintenance tab 56 and second that stretches out from it and keeps tab 58.When retainer 32 rotated, keeper 52 was used for the container 18 in retainer 32 is maintained.The width of platform 54 width with base 33 basically is identical.Usually, platform 54 necessary long enoughs, when making in box 18 remains on retainer 32,

tab

56 or 58 can be meshed with the drift angle of DVD box 18.Platform 54 is preferably flexible, so that it can be along the specified direction bending of arrow 59, thereby allows the insertion and the taking-up of container 18.Platform 54 (and other structures of keeper 52) can integrally be made with finger piece 35 (and other possible parts of retainer 32), as shown in Fig. 5 and 6.In one embodiment, platform 54 can be thinner than finger piece 35, is flexible thereby make platform 54.First tab 56 and second tab 58 inwardly stretch out towards short finger piece 34 from (and being substantially perpendicular to) platform 54.As being clearly shown that among Fig. 9, second tab 58 is positioned at the top (that is to say that the distance of leaving base 33 is farther) of first tab 56.Second tab 58 is also longer than first tab 56 from the extension elongation of platform 54.

The advantage that 34 of first finger pieces extend on about 1/3rd the length of container 18 is that container 18 can be put into this groove shape space (being limited between finger piece 34 and 35) obliquely, thereby does not need the people that keeper 52 is pulled back.This can finish by the turning of the container 18 of the most close first finger piece 34 in position is reduced.When container 18 was put into this groove shape space obliquely, an edge of container 18 was just by being pressed on second tab 58, and made keeper 52 to palintrope (along the specified direction of arrow 59).In case after container 18 inserted in the retainer 32 fully, first and/or

second tab

56,58 was just by being buckled on the container 18, thereby prevention container 18 skids off in retainer 32, as following also to be described in more detail.Certainly, the people also can pull back keeper 52 (for example, utilize finger-like tab 57, this will describe in detail below), to help the insertion of container 18.

First and second tabs 56 are positioned on the different height with 58, and have different length, thereby make the DVD box 18 of two kinds of different sizes can remain in the retainer 32.Size with DVD box 18 is decided, or first tab 56 or two

tabs

56,58 are meshed with the part of this DVD box 18.When with the DVD casket 18 (for example, 7.51 inches * 5.35 inches * 0.6 inch) of first kind of size when putting into retainer 32, this box or casket 18 will be loaded into fully by first tab 56, base 33, and in

finger piece

34 and 35 zones that limited.The short length (for example, being a bit larger tham 5.35 inches) of preferably being a bit larger tham the DVD box 18 of first kind of size from the height of base 33 to first tabs 56.First tab 56 extends along the outer peripheral part of this box, thereby has stoped box 18 to skid off from retainer 32 (when it rotates).

When with the DVD box 18 (for example, 7.47 inches * 5.58 inches * 0.53 inch) of second kind of size when putting into retainer 32, this DVD box 18 will be loaded into fully by second tab 58, base 33, and in first and

second finger pieces

34 and 35 zones that limited.The short length (for example, being a bit larger tham 5.58 inches) of preferably being a bit larger tham the DVD box 18 of second kind of size from the height of base 33 to second tabs 58.Therefore, second tab 58 extends along the outer peripheral part of this DVD box 18, thereby has stoped this DVD box 18 to skid off from retainer 32 (when it rotates).In this case, first tab 56 and second tab 58 all are meshed with box 18.First tab 56 is meshed with the side of the DVD box of facing long finger piece 35, and a positive force that promotion DVD box 18 is pressed against on the short finger piece 34 is provided.This positive force produces a bigger friction force between DVD box 18 and short finger piece 34.Usually, platform 54 is equivalent to a semi-girder, tends to return its original position (for example, extending point-blank from finger piece 35).As at Fig. 6, shown in 8 and 9, stiffening rib 55 stretches out from platform 54 between first tab 56 and second tab 58, and its extension elongation is identical with the extension elongation of first tab 56.Stiffening rib 55 has been strengthened first and second tabs 56,58.In addition, the outmost edge of stiffening rib 55 (that is the edge of the most close finger piece 34) rests on the edge of DVD box 18 of second kind of size that (and being pressed on) inserted.

In case after DVD box 18 was " locked " in retainer 32, this DVD box 18 can only be by keeper 52 being pulled back and leaves this box (that is, along the specified direction of arrow 59) and is " loosened ".In a preferred embodiment, this keeper comprises a finger-like tab 57 that stretches out above second tab 58.When inserting or take out container 18, finger-like tab 57 can be used to make the user (for example, people) can be with keeper 52 bendings (along the specified direction of arrow 59).

Below to describing by adjacent retainer 32 being snapped together the endless belt 23 that forms.Generally speaking, each retainer 32 comprises radial type coupling arrangement or mechanism 50 (Figure 11 B), and this device can make adjacent retainer be connected to each other together flexiblely.In this structure, do not need to use any anything else, only need retainer itself just can form one by retainer 32 the link together loop or the endless belt 23 of (or hinged), for example shown in Figure 11 A and the 11B like that.Bindiny mechanism 50 sets up the endless belt 23 of a retainer, and this endless belt has enough elasticity, and (for example, sprocket wheel 36 rotates turning in the district 11 of the top that for example is shown in Fig. 1 as shown in Figure 12) thereby make loop or endless belt 23 can center on sprocket wheel.Use mutual buckled connector to make that the assembling of continuous loop or endless belt 23 is very convenient, do not need to use any anything else, only need retainer itself to get final product.In addition, as described herein, this mutual buckled connector provides the display rack 10 of standard package character by increasing other retainer (to enlarge the storage volume of this display rack).Be described in detail with reference to Figure 14 below the ability of this expansion capacity.

Again particularly referring to Fig. 5-9, each retainer 32 comprises positive type or ball-type or cylinder shape connector 21 and has hinge nest type or every kind of at least one connector in the Female Connector 17 (preferably comprising every kind of two connectors) of far-end 17a below.Preferably, every kind of connector all forms on the bottom surface 27 of retainer 32.Can be clear that in Fig. 5 and 7 Male Connector 21 and Female Connector 17 are configured in the opposite side of bottom surface 27.Male Connector 21 is outwardly directed bending cylindrical from the bottom surface 27 of retainer 32 preferably.Male Connector 21 buckles in the moon hinge nest 17 of the pairing on the adjacent retainer 32 of the next one.When adjacent retainer 32 was connected to each other, the far-end 17a of Female Connector 17 extended or extend near each Male Connector 21 the slit 25.

As shown in Figure 11 B, sun that (by adjacent retainer 32) snaps together mutually and Female Connector form a hinge 50.This connector helps retainer 32 to be connected to each other flexiblely, and (for example sprocket wheel 36, rotate as shown in Figure 12) so that can center on sprocket wheel.In addition, as shown in Figure 11 A and 11B, when loop or endless belt 23 rotations, this connector can also make adjacent retainer keep the serial relation of physics each other.This close relation helps to make the storage density of display rack 10 to reach maximum.As shown in Figure 11 B, the far-end 17a of each Female Connector 17 extend in the slit 25 of adjacent retainer 32.Far-end 17a can stretch out by the base 33 of retainer 32, especially when 32 one-tenth fan-shapeds of adjacent retainer are scattered.On-stream, when 32 one-tenth fan-shapeds of retainer were scattered, Female Connector 17 slided with respect to Male Connector 21 or rotates.The far-end 17a of Female Connector 17 pass slit 25 up to it near and with till the inwall 68 of base 33 contacts.Far-end 17a can become fan-shaped to spread out into what scope having determined retainer 32 turning in the district 11 with mobile distance before inwall 68 contacts.Each retainer 32 has a pair of from base 33 upwardly extending stiffening rib 70 (Fig. 7,10), is used for stoping the DVD box 18 and the far-end 17a of Female Connector 17 to disengage when Female Connector 17 rotates with respect to Male Connector 21.Stiffening rib 70 plays baffle plate, is used for stoping DVD box and hinge 50 to interfere.As mentioned above and as Fig. 3,6,8, shown in 9, each retainer 32 preferably includes an a pair of interlock of L type 47 that has, and this device stretches out from the surface 27 towards inside of retainer 32, so that engage with for example guide rail or guide 44,46 (Fig. 3), and led thus.

In a preferred embodiment, device 410 comprises at least one light source 420, and this light source just illuminates immediately, and keep subsequently an of short duration time again when being with 310 and 320 (for example by motors 28) to rotate, and the chances are one minute.When the illumination that is obtained can make the user work as DVD to arrive fan-shaped and scatter district 11 they are made a choice, good even display rack 300 uses in a room dark or dim light.

DVD box 18 can randomly carry the bar code information 450 that can discern dvd content.Bar code information 450 can be produced by the user, is perhaps produced by DVD manufacturer.Bar code scanner 400 (be preferably disposed on device 410 in) can turn at the DVD box and read bar code 450 when fan-shaped is scattered in the district 11.

An optional portable telechiric device 460 comprises a keyboard 470, power supply 480 and output translator 490, this telechiric device make the user might make electronic equipment 390 (or the part of this electronic equipment) at least recognize required bar code 450 when device 410 scannings.Device 460 can bar code information use (without limits) ultrasound wave will be required or selected, radio frequency, and perhaps method such as Infrared Transmission is transferred to display rack 400.One is detected these signal transmitted with the interconnected suitable sensors 405 of electronic equipment 390.Need to select certain DVD the user can the suitable identifying information of input on the telechiric device 460 (this information with in telechiric device 460 or the bar code of in the electronic equipment of tower 300, wanting be linked, perhaps be associated with bar code), this information is transferred to sensor 405 subsequently.When being with 310 and 320 to rotate for two, the scan code the sweep limit of device 410 in entrained by any DVD box just identified by device 410, and electronic equipment 390 just makes motor 28 stop operating.If desired, can stopping that motor rotates intentionally be postponed by electronic equipment 390, so that allow the endless belt to rotate needed DVD tape to uprightly configuration more vertically, the box in Figure 16 A 18 ' like that for example.Telechiric device 460 can be a kind of through improving or the not improved general control device that for example uses on TV or video cassette recorder, also can be PDA(Personal Digital Assistant) or the portable computer or the desktop computer of an infrared or compatible bluetooth.Manually type in bar code itself with it, can transmit an abbreviation sign indicating number or an abbreviation identification of representing whole bar codes of required DVD not as preferably making telechiric device 460, this abbreviation sign indicating number can convert to represents this bar code recognition.

In addition, or another way is, electronic installation 390 can be designed to be able to discern some verbal order of being sent and can be detected by improved sensor 405 by the user, for example, and " stopping ", " execution ", " oppositely ", " hurrying up " and " a little slower ".By this way, the user just can stop loop rotation by the verbal order display rack, this user can be not very close to display rack with regard to maneuver

control device

37,37 ', or 37 " (the following describes); but he should be close fully, arrive the top fan-shaped district of scattering with required article of box lunch and it can be identified in 11 o'clock.

By a motor 28 two endless belts 310 and 320 (Figure 16 A) in display rack 300 are rotated simultaneously, this motor can be identical with the motor 28 shown in Fig. 4.Be shown in the Crossed Circle band structure that various drive sprockets among Fig. 4 and pulley assembly preferably also are used for Figure 16 A and 16B.A difference is, in order to drive two rather than an endless belt of forming by the retainer 32 that is connected to each other together, increased the length of axle 40, and a pair of drive sprocket 22 and 24 are arranged in 310 and 320 lower area, and each scatters district 11 with 310 and 320 top fan-shaped in, a pair of driven sprocket 36 and 38 are arranged.Motor 28 fronts in display rack 10 have illustrated it is the bottom that is configured in the framework of this display rack.But in display rack 300, as shown in Figure 16 B, motor 28 but is configured in the top near the framework of display rack.Motor 28 is installed in the top of display rack 300, can reduces formed bending or sagging in the endless belt 310 and 320 when retainer 32 is connected to each other.Because the result of sagging minimizing is, reduced endless belt 310 and 320 for example because the weight of retainer 32 (comprising DVD box 18) and from driven sprocket 36 and 38 possibilities of throwing off.Should be noted in the discussion above that the motor 28 in (for example shown in Fig. 1) display rack 10 also can be configured in the top of this display rack.

Motor 28 (for example its diameter is about 25 millimeters) can be driven by 9 volts of DC voltage that the battery B1 that is configured in the base 360 is provided, and the weight of these batteries helps to make the center of gravity of whole display rack to reduce herein.For example, the D battery of six 1.5 volts DC voltage can be used for driving display rack 300, and perhaps external power source provides operating potential by a power input socket J1.In the preferred embodiment, control device 37 is meshed with a spring-loaded rotary switch S1.On neutral position (being off-position), bearing power and motor 28 are disconnected when control device 37 makes the S1 switch.When the S switch when clockwise rotating, endless belt 310 and 320 beginnings are rotated along first direction (for example clockwise direction), when utilizing control device 37 that the S switch is further rotated along clockwise direction, endless belt 310 and 320 rotation are just slack-off.When the S switch when inhour is rotated, endless belt 310 and 320 just in opposite direction (for example counter-clockwise direction) rotate, when further when counter-clockwise direction is rotated, endless belt 310 and 320 rotation are just slack-off.When the user unclamped control device 37, the S switch just was biased into off-position by spring, and this moment, all loop rotation all stopped, if there is device 410, light emitting diode 420 will make illumination stop one period short time after rotation stops.If desired, except that control device 37, can also be with foot-operated control device, for example 37 ', 37 " are controlled at endless belt 310 in the display rack 300 and 320 rotation and velocity of rotation, perhaps replace control device 37 with foot-operated control device.The speed of motor and direction are preferably adjusted by control and the polarity of the voltage of the interconnected power supply B1 of motor and the size of voltage by the user.

Therefore, and control device 37 (or foot-operated control device 37 ', the similar mode of 37 ") when moving to single annular band display rack 10 (as shown in fig. 1) controlled the operation of Crossed Circle band display rack 300.When the DVD box 18 that required DVD15 is housed on 310 or 320 moved in the fan-shaped on the top of display rack 300 is scattered district 11, the user should stop the rotation of motor 28, thereby the rotation of band is stopped.Then, the user takes out required DVD box 18 again from display rack 300.

Should be pointed out that all and power supply described above, the motor operation, telechiric device, lamp, the relevant structure of parts such as bar code reader can be included in any display rack described herein.

The part assembly drawing of Figure 16 B display rack 300 only shows two retainers in many (for example, perhaps being 200) interconnected retainer 32 that display rack 300 can find usually among the figure.Figure 16 B shows and is used for the internal overarm supports 500 that a vertical member 330,340 and 350 keeps mutually.As mentioned above, during fabrication and afterwards perhaps be under the infrequent situation, the tension force that need to adjust in endless belt 310 and 320 are arranged.Those of ordinary skill in the present technique field will be easy to recognize, using pad or bearing seat (for example 510) is the suitable device of realizing this adjustment.In the preferred embodiment, the left side of the rotation axis 40 of lengthening and right two ends maintain the hollow bracketed part 520 of a left side and right bearing base device 510.The hollow parts 520 of each bearing holder device 510 is being controlled the end of axle 40, and can vertically move up and down, so that increase or reduce in endless belt 310 and 320 by interconnected retainer 32 formed tension force.A projection 530 towards the outside on each bearing holder device is engaged in the slit 540 that forms in vertical member 330 and 340.Therefore, vertically moving up and down of projection 530 will increase or reduce the tension force of band.After required tension force was realized, just the required upright position with projection 530 kept, and for example can bearing seat 510 be remained on the adjacent outer vertical support 330 or 340 by screw 550.But as mentioned above, the other technologies that are used for the tension force in the band is adjusted when needing are well-known in the present technique field, and top explanation is exemplary.
