Description

Component

The invention relates to a component according to the preamble of the claim 1.

Such components are in different designs for play purposes known and can be put together to form different objects, such as buildings, bridges, walls or the like used for gaming. Known components of this type are solidly injection-molded from plastic. Take those in retail as an example under the trade name "Lego" available components named. If you have objects made from such components with lamps or other wants to provide electrical consumers, you previously had to or separate lamps in the objects and lay electrical cables to them separately.

It is therefore a task of the invention, components of the initially called type to create Ce the electrical connection of electrical consumers simplified and made possible in great variability.

This object is achieved according to the invention by a component according to claim 1 solved.

In that the component has at least two pairs of connection contacts, those with connection contacts of other such components when plugging together of these components come into contact are those made from such components Objects or objects containing such components, such as buildings or the like traversed by the electrical lines of the components that made the laying separate electrical lines to lights or to other electrical ones Consume7 those connected to such components or through such components are themselves educated, make them superfluous. In particular, the two connection contacts of the single pair. electrically conductive with each other, that is be electrically connected to one another with practically no resistance. Electrical consumers, for example lamps1 Electric motors or the like can provided with the same connection contacts and attached directly to such components will. However, the component itself can preferably be an electrical consumer contain, preferably at least one lamp.

Components according to the invention thus form both the production of Components serving objects, preferably building blocks, as well as electrical ones Connections to the components or other electrical components attached to it Consumers or additionally. even electrical consumers.

The component can preferably form a lamp, at least a light source, preferably an incandescent lamp, connected to connection contacts is the voltage used to supply the lamp, preferably DC voltage can be applied.

With particular advantage, the light source can be supplied with direct voltage in series with a rectifier inserted into the component, preferably a diode. The advantages of this design will be discussed further below received in detail.

By combining any number of the objects together to form any object Components each form a luminaire themselves, which luminaires are parallel to one another are switched, self-luminous objects result more diverse Art with great variability of their own lighting. In the case of gaming purposes Components of this type result in completely new play options.

However, it is also possible to use components according to the invention for others To be used as play purposes, for example to create objects for shop window advertising, for architectural offices or the like. In such cases If necessary, they can also be made larger than usual for play purposes.

Since it is not necessary in many cases that all components have one objects made from them are provided with light sources, one can expediently also provide components of this type whose connection contact pairs are mutually electrical are isolated, so that such a component apart from its function as a component only has the function of an electrical connection part and is not self-luminous is.

In the already described, particularly preferred embodiment, in which a rectifier is connected in series with a light source of the component is, the DC voltage leading terminal contacts of the component optionally connect so that the DC voltage to the rectifier is either in whose blocking direction or in its forward direction is applied, so that this component either to another component or to a connection plate on which further received below is connected, or in some other way it can be that either the light source lights up when the DC voltage is switched on or remains switched off by the rectifier.

A light bulb can preferably serve as a source of light, but it doesn’t work other light sources, preferably light-emitting diodes, may also be considered. At least then, if the components are used for play purposes, the light sources should be low-iger Voltage can be fed, as is customary with electrically feedable toys.

The supply of assembled from components according to the invention Items with supply voltage can be preferred in the case of low DC voltage by means of a transformer that transforms the mains voltage with a downstream Be full wave rectifier.

In most cases it is sufficient if the component has a Has a single light source. However, three larger components can also have several Light sources may be present, which can preferably be connected in parallel.

Due to the parallel connections that arise automatically when the components are plugged together of their light sources, all light sources can have the same supply voltage.

The light source can advantageously be at least partially inside the be arranged from light-tight material existing support body, so that their light through the relevant transparent walls or wall areas of the support body exits to the outside. The color of the emitted can be determined by different coloring Hit light in the desired way. There can be several types of components be provided, which differ in the colors of their transparent walls, through the objects made from such components even greater variability of their self-luminous components. This expands the game possibilities and the design possibilities of objects having such components.

This means that it has a light source and is therefore self-luminous Component another component attached to it that is also transparent walls has, not illuminated from the inside by light radiated into it, can be provided be that the relevant side of the support body, in particular the recesses and / or side or sides having plug-in parts completely or substantially are shielded against the escape of light. You can also provide at least one another transparent wall of a self-luminous component drawn light exit shield at least partially.

It is also possible to place the light source on an outer wall of the support body, preferably to be arranged completely sunk in an indentation, what their replacement enables. However, since the components are cheap mass-produced items, you can do without also provide that the light source is not exchangeable. When they are broken then you can still classify this component as no longer self-luminous Continue to use the component as it continues to form an electrical connector.

At least in the case of components for play purposes, it is advantageous and normally sufficient to provide that the recess or recesses of the component are designed for the frictional reception of at least one plug-in part. The components can then be friction-locked together and it does not require any additional mechanical connection to hold them together. It is however, it is also conceivable to provide other plug connections in some cases, preferably for holding together the components that are attached to one another, snap-in connections to be provided. In this case, the first connection contact can preferably suitably be a be metallic locking spring and the second connection contact can be a complementary one Have notch.

The plug-in part can preferably be formed by a metallic plug pin (Plug contact) and the recess formed by a metallic socket be, which also form the relevant first or second connection contact. the two connection contacts of the individual connection contact pair can preferably be arranged in alignment with one another on the support body.

However, it is also possible that the plug-in part and the recess are not completely metallic, but contain one or more connection contacts. In some cases, the recess can expediently be a leaf spring or a conductor track as a second connection contact or several leaf springs or conductor track for several contain second connection contacts and the plug-in part can approximate to this recess Be designed to be complementary and accordingly one or more leaf springs or Have conductor tracks as the first or first connection contacts.

It can preferably be provided that the longitudinal center axis of each plug-in part of the component is aligned with the longitudinal center axis of a recess. In this case the plug-in parts and the recesses are located opposite one another ' preferably mutually parallel sides of the support body of the component. Included it is possible that on each of these two sides both at least one plug-in part and at least one recess is provided. It is more space-saving, however, provide that the plug-in parts on one side and the recesses on another Side of the component are arranged.

One can also provide for at least two angled to each other, preferably at right angles arranged sides of the component plug-in parts and recesses to be arranged with first and second connection contacts at for example on only two sides arranged at an angle to one another or on two end faces and one of these connecting side surfaces of the support body, etc.

The support body can preferably have a cylindrical circumferential shape. In this case, its two end faces can expediently be flat and at right angles to the Generating lines of the circumference be arranged. The support body can preferably be cuboid Have an external appearance. However, it is also possible to have at least one of its outer surfaces to be arched, preferably arched in the shape of a circular arc.

Components according to the invention can have different numbers of Connection contacts received in order to make the possible variations of them Objects to increase and the number of arrows to create an object to reduce required components.

The component can preferably have 2-n first and 2.n second connection contacts where n is an integer.

It is possible to use the two connection contacts of each connection contact pair to be connected by a separate electrical conductor, but it is generally more expedient for these two connection contacts to be integral with one another to connect, vorzugqweise to form on a metallic rod.

The connection contacts can expediently be arranged so that the first and second connection contacts each have a matrix with perpendicular to each other running straight lines Forms rows and columns with the same pitch. The individual column and row can consist of a minimum of two connection contacts. If the component has a rectifier in series with a light source has, as is preferably provided, it can be expediently provided that the connection contacts alternate both in the rows and in the columns of the matrix are connected to one and the other electrode of the rectifier. Through this it is achieved that such a component can optionally be applied to it with direct voltage supplying components or to a connecting plate that supplies it with direct voltage can add that the light source is either on or switched off by the rectifier is.

Since different objects from the components according to the invention can be produced, the invention also includes a set of components that a plurality or preferably a plurality of components according to the invention having. The set of components can preferably be predominantly or essentially or consist entirely of components according to the invention.

A connection plate can preferably be provided for connecting the components be that a variety of designed for attaching several or many components is and to come into contact with connection contacts of the components to be placed has serving contacts that form a matrix with straight and perpendicular to this Columns are arranged with the same pitch and that the contacts of the matrix two electrical inputs are connected in such a way that in each row and column adjacent Contacts have different polarity.

The connection plate also forms a base for the construction of objects from components according to the invention.

It is also possible and preferably provided that two or more connection plates to a correspondingly larger connection plate with each other, preferably by means of plug connections can be connected to the cohesion of the connection plates and preferably can also serve their electrical connection with each other. In the drawing are Illustrated embodiments of the invention. They show: FIG. 1 a view from below a 3auelementes according to a first embodiment of the invention, FIG. 2 a section through Fig. 1 seen along the section line 2-2, Fig. 3 shows a section seen through Fig. 2 along the section line 3-3, Fig. 4 is a plan view of a Component according to a second embodiment of the invention, Fig. 5 shows a bottom view of the component according to FIG. 4, FIG. 6 shows a section through FitJ. 4 seen along the section line 6-6, FIG. 7 seen a section through FIG. 6 along the section line 7-7, FIG. 8 shows a plan view of a component according to a Third embodiment of the invention, FIG. 9 is a section through FIG along the section line .9-9, FIG. 10, a section through FIG. 9, seen along the section line 10-10, FIG. 11 is a plan view of a connection plate according to a Ausfihrungsbeispiel the invention, wherein a part of the ceiling of this hollow connection plate is broken away together with the sockets in question to the one on a false floor arranged electrical wiring to be visible, and furthermore some are on they plugged-on components indicated by dash-dotted lines, Fig. 12 a partial section through Fig. 11 seen along the section line 12-12 * Das in the Construction element 9 shown in FIGS. 1-3 has a hollow, cuboid support body 10, the housing of which is made from a main part molded from transparent plastic 12, which forms the ceiling 12 'and the four peripheral walls of the support body 10 and one also consists of transparent plastic injection-molded, flat bottom part 13. In the ceiling 12 'of the support body 10, two square metal plates 15 are through Overmolding embedded, which are used to shield light and each of which is one one-piece metallic rod 14, 14 'with it, which, inter alia. as electric Head is used and at one end a protruding beyond the bottom of the support body 10 Plug pin 16, 16 'and at the other end a plug socket completely sunk into the support body 10 17.17 'forms. The circular cylindrical blind bore of each socket 17, 17 'forms a recess 40 for frictional insertion of a plug pin 16, 16 ' another such component.

The longitudinal axis of each straight rod 14, 14 'is perpendicular to the Ceiling 12 ′ and to the floor 13 of the support body 10.

The socket 17, 17 'and the plug pin 16, 16' of the individual Rod 14, 14 'are electrically connected to each other so that they carry the same voltage when voltage is applied. The rods 14, 14 'are rigid and can for example consist of brass.

Each metal plate 15 extends almost over half the area the ceiling 12 'and they are at a small distance through the plastic of the ceiling 12 'isolated from each other. The two rods l4j 14 'are through an electrical Connecting line 19 connected to one another, in which a small incandescent lamp in series 20 and a rectifier diode 21 are interposed. The rod is 14 ' connected to the anode and the rod 14 to the cathode of the rectifier 21. If you consequently connect the connector pin 16 'to positive DC voltage and the connector pin 16 to ground or negative DC voltage, the rectifier 21 leaves electrical Current through and the bulb 20 lights up. If, on the other hand, the connector pin 16 the positive voltage and to the connector pin 16 'ground or negative voltage sets, the rectifier 21 blocks and the lamp 20 is therefore in the blocking direction with voltage applied rectifier 21 "switched off".

It is assumed that the pin 16 'has positive voltage and negative voltage is present at connector pin I6. The lamp 20 then lights up and this "building block" is then self-illuminating. If you now have a second identical component 9, as indicated partially in phantom in FIG. 2, with its connector pins 16, 16 'in the sockets 17, 17' of the fully extended shown Component 9 is inserted, then the lamps of these two components 9 are parallel to each other switched, taking it. however, depends on whether the lamp 20 of this second component 9 lights up or not, whether its plug pin 16 'into a socket 17' or in a socket 17 and correspondingly its other plug pin 16 in each case the other socket is plugged in. In the former case his lamp lights up and in the second case it is switched off by the rectifier. You can too this component 9 on the connection plate 50 shown in Figure 11 optionally Attach in such a way that its lamp lights up or switched off by the rectifier will. Its electrical connection function to components plugged into it is not affected by this.

Many such components 9 can be inserted into the connection plate 50 and on this in turn further components 9 flush or offset in parallel or Attach at right angles, so that these Baueler.enten 9 objects can be produced in almost unlimited diversity.

Each component 9 can be inserted into the same sockets on the connection plate 50 or in the sockets 17, 17 'of one or two such components beam be plugged in so that its lamp 20 can light up or through the rectifier 21 is switched off.

A second exemplary embodiment of a component is shown in FIGS 9 ', whose square base is twice as large as that of the component 9 and which has four rods 14, 14 '. The two rod groups 14; 14 'are over a line 19, in which in turn a lamp 20 and a rectifier 21 are interposed is electrically connected to each other. Again, the ones at the cathode of the Rectifier 21 connected rods with 14 'and connected to the anode Strength denoted by 14. The support body 10 in turn forms a hollow cuboid, The side walls of which are molded from transparent plastic. the Rods 14, 14 'are designed the same as those of the component 9. The same applies to the component 9 ″ according to FIGS. 8-10.

These components 9, 9 'and 9 "can be used with any of their connector pins are plugged together, so that the connector pins are then each in sockets one or more other such components 9, 9 ', 9 are frictionally engaged here are plugged in for a long time.

All of the rods 14, 14 'of the component 9' are parallel to one another. His Both connector pins 16 are electrical by a common metallic plate 15 ' connected to each other, whereas the other two connector pins 16 'over which they having rods 14 'and a metal plate 15, which is in the ceiling of the support body 10 is embedded, are electrically connected to each other. The two sockets 17 'with associated connector pins 16' thus each have the same polarity and the other two sockets, which are also diametrically arranged to one another 17th with associated connector pins 16 each have the other polarity.

This component 9 '- as well as the component 9' - can optionally be used plug them into sockets 18 of the base plate 50 or other such components in such a way that that its lamp 20 or its lamps 20 either with DC voltage applied to it light up or are switched off by the rectifier 21.

In Figure 5, the polarities of the connector pins 16, 16 'are shown as + - entered, whereby the polarities in brackets are an alternative to the not Polarities in brackets are possible, depending on how it is attached is.

Since each row of nested rods 14 and / or 14 'one above the other plugged-on components, regardless of whether they are components 9 and / or 9 ' and / or 9 ", a continuous, practically resistance-free metallic one Forms conductor whose polarity is only determined by the polarity of the socket 18 of the Connection plate 50 is determined in which the lowermost rod 14 or 14 'of this row of rods is plugged in, you can combine dis components 9, 9 ', 9 "as desired and on top of each other without faulty switching being possible. You can use any component at its x-intended place alternatively so that its L =. »e when applied DC voltage is lit or switched off.

In all components 9, 9 ', 9' are the lines 1 9 with the lamps 20 and the rectifiers 21 are arranged completely within the support body 10.

The center-to-center distances between adjacent plug pins 16, 16 'and plug sockets 17, 17 'are the same size for all components 9, 9', 9 "and correspond to the spacing between centers adjacent plug sockets 18 of the connection plate 50 according to FIG. 11.

Since the plug pins 16, 16 'in the plug sockets, 17, 17', 18, in that they are plugged in, are kept friction-locked, this is sufficient for the Zusaar, contains the components easily and no other connection is required although an additional connection is also possible.

The bottom and the ceiling of the support body 10 of the component 9 'has Triangular signs that are still completely electrically isolated and used for light shielding Open plates so that the floor and ceiling are opaque to light except for narrow strips All circumferential walls of the support body 10 are, however, in this embodiment transparent.

The component 9 ″ shown in FIGS. 8-10 is also cuboid and can in principle be thought to be composed of three components 9, wherein however, its support body 10 has a continuous cavity and only two lamps 20 with upstream rectifiers 21 are present in this cavity. Every component 9, 9 ', 9 "can be applied to a single other component or to several at the same time other components should be attached and thus hold them together. It can be so much erect stable objects from these structural elements, For example, walls, where the building blocks are arranged in rows of blocks one on top of the other are offset from one another, as is common when building wounds from bricks is.

In Figure 8, the polarities of the two groups of rods 14, 14 ' different polarity of this component 9 ″ has the same meaning as in Figure 5 is shown. The electrically resistance-free electrical connections between the rods 14 or between the rods 14 'again form metallic Strips, of which the metallic strips arranged on the sockets are embedded in the ceiling of the support body 10, whereas the remaining metal strips are arranged on the bottom of the support body 10. These metal strips form at the same time again light shields on the bottom and on the ceiling, whereby still in that of This metal strip left free triangular areas of the ceiling and the Fully electrically insulated foils are used on the ground, which also provide light shielding to serve. The peripheral walls of the support body 10 are again transparent.

Since the four peripheral walls of each component in these exemplary embodiments are translucent, every luminous building element can be in a horizontal plane Adjacent components shine light, which enables additional lighting effects. If you want to avoid this, you can, for example, on the relevant sides of the support body Apply 10 opaque adhesive film. It is also possible to have an or several peripheral wall surfaces of the support body 10 at least partially opaque trains.

In particular for play purposes it is advantageous to use the objects assembling components 9, 9 ', 9' 'to build on a connection plate, of in the Fig.

11 and 12 an embodiment is shown. This connection plate 50 forms a hollow body 51, on the ceiling 52 of which is arranged on an intermediate floor 53 Plug sockets 18 end flush. The sockets 18 form a matrix with straight Rows and columns perpendicular to them in the same division. The sockets 18 are connected to two electrical inputs 55, 55 ', afp which two inputs 55, 55 'a cable 54 is connected, the connection to a was not shown DC voltage source is used. In the broken-open area of the connection plate 50, the sockets 18 are indicated by crosses. The wiring of the plug sockets 18 has two main conductors 56, 56 'connected to inputs 55, 55' and diagonally arranged cross conductors 57, 57 ', each of which is a diagonal row of sockets 18. electrically connected to the relevant main conductor 56 or 56 '. the executive 56, 56 'is connected to the next but one transverse conductors 57 and 57'. In each Row and column of the matrix are the next but one socket 18 on the Input 55 and the other sockets are connected to the other input 55 '. This is shown for some sockets by specifying their polarity.

If the components are used for play purposes, they can preferably similarly small dimensions as the conventional, through each other Plug have connectable plastic components.

It is also often advantageous not to use the support body of the component hollow, but solid, preferably made of plastic to be poured or injected and all parts to be arranged in it, such as the rods 16, 16 ', the lamp or lamps 20, rectifier 21, lines 19 and the light shields to be encapsulated or to be encapsulated so that they are embedded in the plastic.

The side lengths of the plan of the support body 10 of the components 9, 9 'and 9' 'are all determined according to the same basic grid a (Fig. 1). The base of the support body 10 of the component 9 is a x 2a, that of the component 9 '2a x 2a and that of the Bauc-lemcntes 9 '' 2a x 3a.

The height of the support body 10 of these components is the same and needs not to be a. The center-to-center distances between adjacent connector pins 16, 16 'and correspondingly the mutually adjacent plug sockets 17, 17', 18 a.

The longitudinal axis of each rod 14, 14 'passes through the center of a square Surface section a x a of the base through, this base from such square surface sections is composed. This means that components which are plugged directly next to one another on the connection plate 50, without any space to each other and the same applies to components attached to each other and for components that are in other horizontal layers immediately next to each other are arranged. Components of different heights can also be provided, whereby the height can also vary according to a basic grid size.

A kit consisting of components according to the invention can of course also contain differently designed components than those shown or in addition to components 9, 9 ', 9' 'still further components of other dimensions according to the same Basic grid included. Examples are also shown in Fig. R-11. With 9a is denotes a structural element which comprises a single row of three straight bars 14, 14 ' contains and with 9c an angled component also with three rods.

Such a kit can also have components according to the same grid, which have no lamps and rectifiers, so only rods 14, -. 14 'as a through conductor and thus, in addition to their building block function, have the function of electrical connecting parts.

One can also provide such an electrical connection part to form the serving component according to the smallest possible grid, d. H. it only to be provided with a single rod 14 and its square base To give side lengths a, so that it corresponds to half a component 9 without a lamp. Such a component 9b is also shown in FIG. 11 and can in particular filling in a gap in the edge caused by moving other building elements Such a kit can also have components that only have connector pins and do not have a socket which is used as the upper termination elements of such Building blocks erected "walls" or the like.

can serve and can also contain at least one lamp. It is also conceivable to add components to such a kit and receptacles are not electrically connected to each other, so they act as circuit breakers can serve.
