Be used to the wind2 that makes the apparatus and method of springs preload and comprise described device
The present invention relates to according to claim 1 as described in the preamble be used for making the device of springs preload, according to the wind2 as described in the preamble of claim 21 and the method that is used to make the springs preload of wind2 according to claim 28 as described in the preamble.Especially, the present invention relates to and will be used for for example wind2 of screen of data carrier, this screen remains on reeling condition usually and is put in the box on the ground.By this screen is upwards extracted out from box this screen is launched, subsequently, upon deployment this screen is suspended on the special support.
Various wind2s are used for different kinds of information and carry screen, are used to show screen, roller blind of filmstrip etc.These devices have certain to be wound on screen on the carrier usually, and this carrier is generally tubulose, and screen can launch from this carrier against the power of spring, and spring then is loaded with tightening force by this action.When screen will be wound on the carrier once more, will " automatically " carry out by the power of spring, this action will discharge tightening force.But, in order successfully to reel, must carry out certain prestrain to spring.Guarantee that prestrain is a problem, because whole device is usually located in certain outer hull, and this prestrain is carried out before must be in finally being assembled to this housing.This spring force is very big usually, to such an extent as to need special tool, and when carrying out prestrain, injure the danger of operating personal in addition.Therefore, this operation is undertaken by maker usually.
But, may occur the situation that prestrain disappears usually or need for a certain reason prestrain is regulated.For example, when wind2 falls on the ground or collided or prestrain is disappeared, like this, whole screen is wound up in the box that may surround this device.So, under the situation of not taking whole device apart, can not carry out prestrain again to spring.Adopting outer case and this screen to be wound under the situation in the box, even can not touch screen fully and screen is extracted out, this makes this device to use.For this design conditions, at this moment need whole device is transported back to maker, and then take this device apart and carry out prestrain again by maker.
Because therefore the thickness and/or the hardness difference of data carrier or screen etc. wish to readjust prestrain.When screen is loaded with permanent chart especially like this.These charts usually xerox or figure punch on various types of films, paper or textile material, then that they are stacked and be fixed on the carrier screen.Film or paper are thick more, just must apply big more prestrain.Sometimes thin material is also harder, at this moment also needs bigger prestrain.About the problem of prestrain mainly is to occur when the screen rollback.Different sandwichs has different hardness, and some material is very difficult reels, because they are very hard, therefore needs to increase prestrain.
When screen is used to show various images or during as data carrier, importantly carries out suitable tension when extracting out,, and can the observed person see so that guarantee that image is open and flat and can correctly read.
The purpose of this invention is to provide a kind of solution to the problems described above, this purpose realizes that by adopting device as described in the preamble as claimed in claim 1 this device also has the described special characteristic of characteristic of claim 1.This purpose can also realize by using as independent 21 described inventions and independent claims 28 described methods.
By pre-load means of the present invention and wind2, its medi-spring can be from outside prestrain, and it has such advantage, promptly can carry out prestrain to spring under the situation of not taking wind2 apart.This means that anyone that use this wind2 at any time can make the suitable power of springs preload simply, quickly and safely.Therefore, can eliminate the whole wind2 that will comprise screen and box once more and transport maker back to keep in repair extra cost and the work with prestrain.Therefore saved the time, and can be so that safety and simple mode are carried out prestrain more under the situation that does not need special tool.Another advantage is that before delivery, maker certainly carries out prestrain with identical method when spring being carried out prestrain for the first time.
Another advantage is to regulate prestrain with plain mode from the outside.
In a preferred embodiment, the projection of locking piece is elastomeric, so that can compensate the play between the parts of wind2.
Can understand more feature and advantage of the present invention by dependent claims.

Fig. 1 is used to represent the wind2 of prior art.It comprises the coil spring 1 around bar 2.A helical spring end is fixed on the end of bar, and this end is called first end 3, and this bar is as first supporting member 5 of spring.At second end, 4 places of bar, second supporting member 7 is mobilizable to be contained in the outside of bar and to be fixed on second end of spring.Attaching parts 9 links to each other with second supporting member, so that second supporting member is linked to each other with the exterior tube (not shown) of this spring of spring and encirclement and supporting member.Therefore, second supporting member 7 and attaching parts 9 have endoporus, and bar 2 (first supporting member 5) can rotate freely in this endoporus.Second end of bar has pin 10, and this pin 10 protrudes into the outside of attaching parts and surrounds the outside of the pipe of this spring, supporting member and attaching parts.Then, both can also can select by when first supporting member 5 is maintained fixed, making the rotation of second holding device 7 (and attaching parts) make springs preload by when second supporting member 7 is maintained fixed, making 5 rotations of first supporting member make springs preload by pin 10.In fact, the meaning of a kind of method in back is that the prestrain of spring realizes by the rotation exterior tube, in this exterior tube, guarantees to connect by friction.Exterior tube is longer than this bar usually, because the length of bar is determined that by spring the length of exterior tube is carried the width decision of screen by information to be rolled.Bar usually within it side (promptly at the first supporting member place) certain type guide support is arranged, to prevent the inboard friction of spring and exterior tube.
When the device of the type was used for roller blind, it also was provided with the blocking device (not shown), and this blocking device is usually near attaching parts, and this blocking device can be locked in roller blind extracts the position out.On the other hand, when wind2 is used for the screen of extracting out of other type, for example be used for the screen of projector slide, when being used for the data carrier of display screen and other type, usually, the screen of the expansion that should upwards extract out is extracted support or the holding device that end is equipped with certain type out at it, rod member for example, thus screen is strained.
In the later case, usually, wind2 is arranged in certain box, and screen is involved in this box, thereby protects this screen when storing.This box as shown in Figure 2.Illustrated embodiment preferably is used to be the data carrier of screen form, and nonvolatil chart or out of Memory are arranged on this screen.But, wind2 of the present invention is in no way limited to this purposes.The springs preload device 14 of the wind2 12 with good grounds first embodiment of the invention shown in Fig. 2.Represented an exterior tube 15 among the figure, this exterior tube is surrounded spring, first supporting member, second supporting member and attaching parts.In the outer end of attaching parts and pipe certain lid 16 is arranged usually.Can also see the pin 10 that from first supporting member 5, protrudes.On the wind2 of prior art, provide this pin usually.In the embodiment shown, pin 10 is as the control piece of springs preload device.In order to keep prestrain tension force, need blocking device 18,19 to prevent relaxing of spring.In the example shown, this blocking device comprises first locking piece 18 and second locking piece 19.First locking piece 18 is represented more in detail in the Fig. 4 that amplifies.As shown in Figure 4, first locking piece comprises a packing ring that central opening 20 is arranged, and this central opening 20 makes packing ring can shift onto on the pin 10.The shape of opening 20 cooperates with the geometric configuration of pin 10, thereby it can be rotated with described pin.Packing ring has projection or bump 21.In illustrated example, two such bumps are arranged, but their number can change arbitrarily.Graphic bump is such manufacturing, promptly passes packing ring and forms two slits, makes the material deformation of slit one side subsequently, so that make its sagittal plane of bending packing ring, and forms the thing that is called wing plate or convex shoulder or resilient tongue.This makes packing ring have elastic behavior, and this packing ring can be similar to the spring lock washer.
In the Fig. 3 that amplifies, represented second locking piece 19 in detail.This second locking piece 19 also is a packing ring, and it is located at the inboard of an end wall 13 of the box that surrounds this wind2 with being integral, and described end wall is preferably at an end that carries out the prestrain operation.The geometric configuration of this packing ring 19 matches with first packing ring 18, and therefore, in a side that is used for that side contacts first packing ring 18, that have projection or bump, this packing ring 19 also has projection or bump 23.But, the bump of second packing ring 19 does not have elasticity.In the illustrated embodiment, they are designed to a plurality of closely adjacent ridges, these ridges extend along annular at different radii place, distance packing ring center.The height of each ridge changes like this along annulus, promptly has one at least at a place by reducing the convex shoulder that forms highly suddenly, promptly forms one substantially and the rectangular surface, sagittal plane of packing ring, and it is as the corresponding wing plate of first packing ring or the block piece of convex shoulder.All ridges all are equipped with such convex shoulder in the identical bits along annulus, and like this, all ridge forms described block piece together.These ridges of second locking piece can certainly be other different shapes, as long as their other parts on its side surface form the mating surfaces that the corresponding contact surface with first locking piece adapts, its difference is that projection or bump are arranged to mirror image, thereby the locking piece of winning can only be rotated with respect to second locking piece along a direction.Along the rotation of permission direction the time, comprise that the mating surfaces of bump will be in contact with one another and slide.When attempting with another unallowed direction rotation, bump will block and lock each other, thereby prevents to rotate.
