Description

Collapsible multi-purpose globe With the invention, a whole new way, a change and a substantial improvement of the previous methods teaching geography, history and politics Lessons etc. can be made accessible.

The invention should finally give teachers and students the opportunity to by using particularly large visual material that is cheaper to produce to meet the demands of modern times in every way, the teaching thus also to adapt to the requirements of the modern age in these areas.

The atlas and the flat maps. can only do the real thing to a limited extent Convey the worldview. The ongoing political changes mean that there are new editions quickly outdated again. Map and atlas, however, always remain a foolish representation; and even the most skilful projection can only approximate the correct proportions especially when it comes to large-scale issues.

The globe, however, will always be the best and most natural rendering of the Enable earth's surface. A use of the globe in teaching includes erroneous conceptions in these areas from the outset. Distances, and The proportions are true to scale, regardless of whether they are at the equator or at the poles.

however, the known globes also have disadvantages. The negative Properties seizii briefly mentioned here: They are, in terms of their practical performance measured, too expensive, for teaching purposes too small in transport impractical, easy to damage, poor possibility, sow cheap and quick to repair, and finally printed much too cluttered, as they are as possible Bring everything that is important at once.

In newer models, interior lighting is nio.ah provided, which looks very decorative, but has no use for the learner or leaning. Larger models with diameters over i m can sometimes be found at trade fairs and world fairs see etc; but it is always only a matter of one-offs that are too Serve advertising purposes and in no way claim to the exactness of the Wiredergabre of the world view place. All of these models are: but also not paintable or washable a blackboard so that the lecturer can use the added colors to complete what has been discussed can still illustrate and for the next user the drawings quickly can be removed again.

Smaller models are imprecise and also primitive in execution. All varieties are difficult to transport and also very sensitive. they are unsuitable for clear drawing or for changes. The models of the. As already mentioned, teachers are overloaded with too much insignificant things clearly laid out for the student. For class instruction, however, they are decided too small = n.

S.o. teachers and students, traders and industrial companies make do with it always prefer to use maps, although the use of a globe for certain Purposes would be much more beneficial.

In order: to put an end to all these abuses and to open up new paths and possibilities for teaching, it is. necessary: i.- that. cheap production is made possible, transport is made easier: it can go and even larger and large models can be carried in the pocket from one place to another; a. that even the smaller models can still be produced in sizes that do not impair the clarity in any way and yet can combine the same advantages of the large versions; 3. That the models are only partially printed, can be drawn in later for special purposes and can be used again and again thanks to the washability; these tasks are solved by the invention. Even the use of modern material, especially rubber, plastics such as P: olyvinyl chloride etc., or light metal, clearly shows the departure from the path described so far; In addition, there are no transport difficulties, even with the largest models, because all models are collapsible and therefore easy to transport.

The Drruok offers the current state of the printing technology possibilities no particular difficulties. Slight relief-like elevations for certain Contours etc. for stone models can be used when making the balloon envelope, So the bladder, b: be taken into account. You are still through the street noticeable. The advantages that open up here are obvious. Sire .be again briefly, summarized: i. Unbreakability; z. easy transport , by folding; 3. Cheaper by using Giunmi, polyvinyl chloride, Press stiffeners and light metal; q. unlimited size manufacture (especially important for object lesson); 5. Paintable and washable surface, especially Recommended for the large display models that may only be partially printed (Contours) are to make what has been discussed visible by drawing, etc.; 6. Surface design already during casting (for special models); 7. Use multiple differently printed outer sleeves for different purposes for the same bladder, the same bracket and the same base.

A school z. B. can therefore, over several. various large globes have by having only one model with multiple outer shells z. B. to Representation of the distribution of religions; des. oil, forest areas, industry etc. ... serve. So a completely depressed model can just as easily be set up and at the next lesson in another class, e.g. B. one only with the Kontinentkontureri printed model are put into use, whereby just need to swap the outer shells. This is completely new, progressive and, unique.

That also means all sorts of possibilities in the field of advertising are open, should only be mentioned in passing. - It goes without saying that the invention also meets all other demands made on a globe.

According to the invention, the globe body consists of: a rubber bladder, and .an outer shell, for example polyvinyl chloride or a similar material. the The bubble rests like a football bubble in one of the size of the corresponding model adapted shell, which is put together from several parts. Big beach balls may be given here for explanation. Polyvinyl chloride has the property to expand only to a small extent, so that a spherical shape is still always, too with large models, what is not always the case with an uncovered bladder is guaranteed Is likely to be the case. It is also very easy to print and also easy to use in different sizes To produce basic colors. This shell gets its shape: by the pumped in resp. with smaller models by the blown air. For this purpose is at the point which will later become the South Pole, a valve is brewed through which the air is blown in or is pumped in.

Once the bladder has reached its proper size, on which its correct wall thickness depends, then the envelope is also taut: and taut. In addition, the built-in Achsre, which, depending on the size of the model, consists of a strong thread or cord, is stretched inside the bladder. The cord leads from the north pole through the center point to the south pole and is attached to the two holding devices. This ensures that the size intended by the manufacture for the model in question cannot be exceeded. Bladder, cover and acbs cord are to be selected for the corresponding sizes so that they: can easily absorb a certain overpressure.

The soul or axis of the earth, if you call this cord that wants, is not stretchable and shows the exact diameter in its tensioned state of the model in question. As already mentioned, it stands with the two holding devices at the north and south poles in a fixed connection. The two holding devices are the same incorporated into the Blaise on both sides, and the shell, i.e., the wearer of the View of the world has only circular breakthroughs at these points, those at their The edges are somewhat reinforced for reasons of tear. Polyvinyl chloride is only available here as Example: has been given. Of course, other, similar plastics can also be used be used. The bladder is opened through these openings when the device is completed introduced into the interior. In general, it will always remain in it, it can but can also be easily removed again, -as it is z. B. is necessary when to a Basic device several, different, purpose serving outer shells are available. The holding devices also form the rotating and bearing devices of the Globe. The lower south pole holding device is also the valve. A bracket for the finished ball is provided for each size. This bracket is available in several Parts can be dismantled. The usual graduations are on it. Its presence also makes it easy to label the model in class.

The connection of the bracket holding the finished globe with the as The base plate serving packaging transport box is created by a foot, which is anchored in the box and a push-in device at its upper end for the lower part of the temple.

After releasing the air, the envelope and the bladder can about Folded and rolled up in the manner of a beach ball, then together with the also collapsible bracket and the foot that is still inside takes up the paint box, in the packaging box that also serves as a base plate to find their place in the form of a suitcase. The device can then be transported again and protected from any damage. Of course you can also use the finished globe leave it where there is space, etc., making it appear more profitable.

The size of the packing case is roughly the same. half the diameter of the respective model and can be a little larger than smaller. The floor plan of the suitcase when lying down is square. The device, especially the foot and the Transport box, allows a variety of variations in shape, size and design to. But this hardly changes the principle. In the following part of the description the invention is explained in more detail with reference to the accompanying drawings, wherein a more precise, further description of the outer shell and the bladder is dispensed with can be, since these have already been sufficiently described above and drawings to appear superfluous.

The invention is shown in figures. Because shape and appearance of a globe in the way that everyone is familiar with its way of working can refer to a more precise representation of externals can be dispensed with.

Fig. I represents a cross-section through the assembled globe which actually consists of globe bodies. as in the first part of the description mentioned, from a rubber bladder of appropriate strength, which is inflated by air. It is enclosed in a plastic cover that is attached to the outside with the Earth map etc., depending on the purpose and use, printed or. is partially printed. the The resulting ball is held by a bracket that can be divided into several parts can, through the holding devices d and: e at the north and south pole in the correct oblique earth position held at an inclination of 231r °.

The two end points of the bracket are shaped so that they are the finished Can easily accommodate the ball and allow easy rotation. The camp points of the globe itself are attached to the north, d and south poles and inside the Kurgel connected to one another by a solid cord b. This cord limits that respective size of the ball and serves at the same time to increase the strength of the Bow, which consists of several parts.

While the holding device at the North Pole is only available as a. Bearing and locking knob serves, the air inlet and outlet valve is installed at the same time at the south pole. With the connector, which is also described in more detail below and is firmly connected to the lower part of the bracket, the connection is made with the stand f made. This in turn stands through opening I (Fig.a) going through it, in a recess l (Fig. ¢) in the base plate of the transport case J, which at the same time, laid flat, serves as a base.

For the sake of stability and the cheaper. Accommodation in the suitcase the base has a rectangular cross-section and is positioned diagonally in the box.

Fig. Z shows the schematic representation of a plan view,: from which can be seen that: the foot, in the diagonal and also the bracket in are in the same direction. The dotted circle indicates the size of the globe in relation to the base, i.e. the transport case.

All representations, including the other images, show the in Many attempts have found the best approximate external size ratios of the various Individual parts to each other.

Fig. 3 shows the transport case closed for the finished transport and Fig. 4. the same opened, it being pointed out again that the Transport case once all parts of the disassembled Globusses and secondly when installed as. Stand plate is used.

In Fig.-q. is the breakthrough through the thief of the suitcase in the To see the diagonal direction and also the corresponding arrangement the recess in the bottom of the case. During transport, i.e. when it is packed Device, the Dieckeldurchbrucli: by an inward yielding, by a Spring self-closing plate closed, so there, B the top plate again appears complete and is also dustproof. When installed, this locking plate gives which bears paper and spring on its long side, turn inwards as soon as the base is introduced from the outside.

The recess in the bottom of the transport box is also shown in Fig. ¢ clearly visible. It corresponds to the opening in the lid, so it is included hegezt: the suitcase ready for the installation exactly under this.

The case itself has a transport handle and a practical snap lock provided (Fig.2i to 2q.), of a square plan and reached with its side lengths about half the diameter of the inflated globe of the respective model. Its inner height is chosen so that it can accommodate the upright stand can. So is the strength of the individual. Temple parts chosen so that they, flat placed one on top of the other, can be accommodated if necessary and thus of greater breadth of the foot. This division means that a good half of the transport case remains for the rolled up envelope and bladder. Further This will be discussed more clearly below.

The lid of the case is conveniently connected to the front panel! connected to the case (section 4.) to enable easier packing and unpacking.

Fig. S shows the globe bubble at the North Pole in cross section. The holding deviceid is with: a - washer @ o in the rubber cover, which is specially reinforced at this point poured or glued. This disc is solid with the one passing through it the lower part of the deviced connected and airtightly embedded in the rubber, The upper part, the holding device, consists of a removable cap screw which, since it is supposed to be used by hand for regulating, # vecke, -a strong one Has a corrugated head. The neck of the screw serves as a bearing and pivot point for the north pole of the globe body. On the inward-facing part of the holding device there is an eyelet that serves as an attachment point for cord b.

Fig. 6 shows an external view of the holding device d and illustrates at the same time the storage 'around upper bracket part C. By the protruding, from the Globus envelope out-looking piece of the lower part of the holding device d is the Distance of the bracket from the globe envelope is determined. The neck of the screw of the upper Part -is enclosed by the two ends of the bracket part. The screw option serves that one; in. is able to turn the globe body too easily by: pulling the brakes or achieving complete locking of the legs.

Fig. 7 shows the opposite side, i.e. the holding device at the south pole, and Fig. 8 the mounting of the south pole holding device. To the; Attaching the oils, which are attached to both holding devices on the inside of the globe bubble, to make it easier to see, a rotation of 90 ° has been made in Fig. 7. The holding device at the South Pole also serves as an air inlet and outlet valve and must therefore accordingly, at least for; Models up to 5o a diameter of the globe body, be a bit larger, because the air duct runs inside. In the case of large versions, it is advisable to install a safety valve, as is known to us from bicycles. For no.r, paint versions with a diameter of about 50 cm, a simple injection valve should be sufficient, which is provided with a cap with an internal screw thread and a rubber sealing disc inside.

The bracket is divided into several parts. As particularly useful the result was to disassemble the retaining bracket into five parts. Because the size of the globe Yes, it has to be in a certain relationship to the foot and to the base plate, is this Dividing into five is particularly recommended, because the individual temple parts should be in the Transport box, which serves as a base plate, can be easily accommodated.

Fig. 9 to 16 illustrate the construction of this bracket. The three ; middle parts are perfect in shape. the same (Figures 9 and 13). The two end axes are; constructed at their outer ends protruding (section z6) to .as bearing points to be able to enclose the holding device end and e. The compound stirrup thus represents a semicircle, which the earth in the known on every globe Way spanned. It is made of light metal. Or appropriate similar ones Fabrics and asked a rectangular cross-section. On the side facing the globe is the temple ape. At each end, the parts of the bracket are tapered in such a way that that they each fit tightly into the following part. Similar to the The individual parts are then put together together with toy railway tracks. Small. Bulges p and g, shown in Fig. 9 and io, ensure that the itself is increased by a clean, properly fitting manufacturing firm fit.

A certain amount of force is therefore required to move the parts put together and pull apart again. The fact that de bracket parts are open on the side facing the globe (Dept. i o, 15 and 16) a yield when assembling and springy springing back after overcoming of the elevations or depressions. The bracket can only be finite to a certain Assemble or disassemble Krafta-uf-use. Take the two flat sides the usual graduation. Fig. I i illustrates the compound Bracket with globe body and holding devices. The small dotted lines on the Retaining bracket b, indicate how far the tapered parts into the individual bracket parts are inserted.

This construction ensures that once the bracket itself already has a certain strength, although it is composed of several parts is what is very important especially with large models, and that; he through at the same time the globe, inflated tightly with air, the expansion of which by the inside of hers Cord located inside; eats regulated, is held. So it's mutual here Pre-tied support, which on the one hand achieves great stability and yet both parts, the temple as well as the globe body, are largely relieved. The air in the globe envelope or bubble stretches the connecting cord from the North Pole to the south po, and is not stretchable beyond its actual length. If inflated or inflated too tightly, the globe would only be in the equatorial direction can change, because the dem. respective model, another precisely adapted cord Prevents the two pole points from diverging. The bullet would be in such a Fall; hit the bracket and lose its ability to rotate. Because the bracket with its end tabs only the neck, which encloses the holding devices, it can If the air is filled correctly, it does not lose its semicircular shape either inwards or outwards. So he himself is not subjected to any kind of stress; his task is there only in that it enables the globe to rotate, supports its weight and the connection to the foot and thus to the base plate, the transport case. In Figs. 12, 13 and 14 the individual parts of the bracket are shown again in side and front view shown. The bracket (Fig.13) has three identical parts. Fig.12 shows the north pole end piece of the bracket and Ahb. 14 the south of Poland dstünk. The latter is also. a little longer, since it does not take up another extension.

Fig. 15 shows again a middle part of the retaining bracket in the view representation, while Fig. 16 shows the projecting end parts with the openings and slots for the Taking up the holding devices, which they enclose, so to speak, like pliers, shows. After the two ends of the bracket, they narrow again in such a way that they approximately i are up to 2 mm smaller than the neck of the holding device. Because the bracket is open on its inner narrow side, the end tabs go when inserting the The completely inflated globe body spreads out with light pressure, then springs again return to their old position and hold the two retaining devices on the ball tightly encompassing this itself.

The shape of the globe, which of course has the shape of a must have a regular curl, therefore, arises even from the inner cord, the the pole distances are determined, and for twofold by regulating the air with screws on the valve. Expediently, it is 'inflated so that' the globe body is initially completely is tight and due to the hindrance of the tension cord inside already; on Tried to go out the equator, what, but already in a limited way through the plastic cover Dimensions is prevented. Then the bracket is attached, with the ball through the holding devices connected and the excess air vented until the globe body is the exact one Has assumed spherical shape, which is easy due to the even distance between the shell and the ; attached bracket can be determined.

The base of the bracket c, so the piece that is at the south pole holding device, is firmly connected to the holding piece h in the middle of the outer narrow side of the outer arch. With this connecting piece, the bracket can be pushed into the rail provided in the upper part of the foot like a viewfinder on cameras (Fig.17, i9 and 2o). Due to its shape, which resembles an inverted U , i.e. is open in the middle, a tight fit is achieved, so that a really firm connection is made after pushing together. The mode of operation is shown again in Figs. 17 to 20.

The base f itself is hollow on the inside and at the same time serves as a receptacle for an inner case i, which contains the colors for demonstration purposes tts ,, iv. (Section 18). In the lower part of the foot, better now called the foot sleeve, i.e. on the part that disappears when it is inserted into the transport case, slots are cut in the shape of a uni: ten U with long legs slightly bent outwards, so that they are at least ns 1 mm at their free ends. protrudes. If the stand is now connected to the transport case when the device is set up, i.e. when it is inserted into the case through the automatically yielding flap through the lid and pushed into the recess corresponding to its cross-section on the floor, the both tongues s, which act like springs, after passing the lid opening again and prevent your foot from being pulled out again. So there is a firm, non-wobbling connection between the foot and the transport case (base plate).

When dismantling, the case must first be opened again, then be the two resilient tongues s pressed in with the thumb and forefinger, and foot and Suitcases can be separated again. Figure 17 clearly shows the locked foot in the transport case in section across the diagonal.

Figures 21 to 24 finally show the transport case again in different representations. In top view Fig. 21, in section through the diagonal A: -B Fig. 22, front view Fig. 23 and section C-D Fig. 2q .. They only serve the explanation as to the attachment gong of the handle in with the tabs n .an the lockable front and the practical storage of the dismantled parts in a transport case. In the case of large models, when transferring the ratios, : which were taken as a basis here, even space for a pump in the transport case.
