Description

I. The technical field to which the invention relates.

The invention relates to a connecting device for fixtures, in particular for ceiling fixtures.

II. State of the art

In the case of mounting the lamp on the ceiling of the room during construction, a cable is usually removed from the ceiling, which in most cases ends in a plastic receptacle of a hidden installation, embedded in the ceiling in the form of a flat cup, and sometimes also in an outlet of an open installation. This socket of a hidden installation serves only to place the end of the cable in it if necessary and close it with a plastic cover, creating an attractive appearance.

If it is necessary to install the lamp in the ceiling, it is necessary to screw the hook, in most cases, through the socket of a hidden installation in order to hang the lamp to it.

By means of a cap that covers the diameter of the socket of a concealed installation from above and can move, for example, upward along the central rod of the lamp, the entire device, after connecting the cables through the chandelier clips, is closed by moving the cap up to the ceiling.

Another possibility is that a fixture is provided on the luminaire, which is applied directly to the underside of the ceiling and screwed to the ceiling, in most cases radially outside the periphery of the socket of a hidden installation, and when drilling, it is necessary to pay attention not to damage the electrical wires leading to the outlet in the ceiling.

Also in this case, such mechanical fasteners should be closed with the hood displaced upwards.

In most cases, these works are time-consuming and cause debris, including because for each fixture it is necessary to adapt mounting holes, hooks, and so on. At the same time, it is also difficult to carry out the suspension so close to the ceiling that in most cases a fairly short cap will also cover the suspension.

In addition, it is necessary to connect the electric wires to the lamp with chandelier clamps, which also often causes problems, especially when the cable end protruding from the ceiling is very short, and also when it is very long, because in this case it is difficult to place it in the unit so that it is not visible .

III. Disclosure of invention

a) Technical problem

The objective of the invention is to provide a connecting device that would provide quick, simple, reliable and non-debris mounting and dismantling of fixtures, in particular ceiling fixtures.

b) solution of the problem

This problem is solved by the features of paragraph 1 of the formula. Preferred options are given in the dependent clauses.

Due to the combined mechanical-electric quick-disconnect coupling between the building and the lamp, by means of a single coupling and its connection, the lamp is mechanically held and electrically connected, which dramatically reduces the installation time and completely eliminates the occurrence of debris and drilling.

Due to the fact that the built-in block, made in the form of a block of flush-mounted or open installation, contains or accommodates a mechanical coupling, after one-time necessary fixing of the built-in block, made, for example, in the form of a block of hidden installation, to which the following description exclusively refers without limitation the scope of the invention, when replacing the lamp no longer requires re-drilling.

For example, the coupling half is fixed in the socket, preferably detachably, primarily to facilitate the connection of a cable protruding from the wall ending in the socket.

If the coupling half is stationary in the socket, around this coupling half there should also be enough space for connecting cables inside the socket without first removing the coupling half.

Preferably, the cables are mounted on the coupling half with unusual screw clamps, which is time-consuming and requires preliminary removal of insulation from the cables, and by simply inserting the raw ends of the cables into the clamps, which, for example, due to the voltage of the springs, contact the cable through the insulation and hold it.

The socket is preferably cup-shaped and can be fixed in the ceiling of the building with a screw connection or with retaining spouts protruding sideways into the masonry if the socket during manufacture, for example, of the floor of a building, is directly embedded in the said ceiling.

The next possible screw connection can be made either through the base of the bowl-shaped outlet, or through screw holes made outside around the flange that envelops the open end of the outlet.

The socket can have a central rod protruding from the base, which, on the one hand, can serve for the correct positioning of the coupling part mounted on the lamp, however, at its free end it can directly contain the electric part of the coupling, in particular, if the electric part of the coupling consists of central coaxial annular or central point contacts, which are often used, for example, in removable electric boilers.

The mechanical part of the coupling preferably further includes a locking device to prevent its accidental separation. This mechanical part of the coupling may also include a cover with corresponding mating elements, which serves to close the socket if the lamp is not connected.

The mechanical joint by which an electrical connection can also be created can be realized by various movements.

With a purely axial articulation, the part of the coupling fixed to the lamp is at least partially axially inserted into the socket and fixed in it in the corresponding mechanical locking elements, made, for example, on the central shaft or on the inner peripheral walls of the cup-shaped socket.

If the electrical part of the coupling is made independent of the position of rotation, for example, due to centrally located coaxial, ring-shaped, electrical contacts, then the mechanical coupling must be introduced regardless of the position of rotation.

If the input with respect to the position of rotation is achieved by means of a mechanical coupling non-circular around the periphery, for example, by means of a positioning nose in a certain place on the periphery, then due to the always correct position of rotation, the electrical contacts in certain places on the periphery can be made in the form of separate connectors for separate phases and neutral wire located in the end surface of the mechanical coupling.

If mechanical fixation is carried out due to rotational movement, for example, in the case of a bayonet lock or due to a simple thread, then preferably always coaxial ring-shaped electrical contacts should be provided as electrical contacts.

Only in the case of a bayonet lock are certain end positions reached so that simple plug-in contacts can be provided for the electrical contacting in the locked position of the bayonet lock.

The coupling half provided on the luminaire can be rigidly mounted on it, first of all, if the proposed connecting device were adopted as a standard, however, preferably any luminaire should be adapted to be equipped with this connecting device, which, in turn, must itself be made with the possibility of mechanical fixation on the lamp and contain connecting clamps for cables leaving the lamp, which, in turn, are closed towards the premises.

In one preferred embodiment, in particular according to paragraph 14 and the following paragraphs, for any electrical contact in the electrical part of the coupling in at least one of the two coupling halves, a coaxial ring-shaped electrical contact located in the center relative to the longitudinal axis is used, whereby both coupling halves in any the rotation position around the longitudinal axis can be inserted into each other and reliable electrical contact is always achieved.

This does not exclude the possibility that with the same electrical contacting such ring-shaped electrical contacts can be provided in both halves of the coupling, however, this usually increases the cost of manufacturing a connecting device.

For this purpose, one half-coupling is made in the form of a sleeve, and the other in the form of a plug suitable for the sleeve, which have a circular cross section and therefore can be inserted into each other in different rotation positions with respect to each other.

Nevertheless, between the two coupling halves, i.e. between the plug and sleeve halves, a rotation stop is preferably provided, which acts at least in the inserted or partially inserted and fixed state of both coupling halves, for example, in the form of a multi-toothed profile on both parts, i.e. the inner ring gear on the sleeve part and the outer ring gear on the plug part, which in the inserted state are engaged with each other and prevent the rotation of both parts relative to friend's friend

This is necessary, first of all, when fixing the sconce, as well as rotationally asymmetric pendant lights, in which the once established position of rotation must be maintained relative to the rigidly mounted recessed unit.

To maintain radial positioning, the plug or sleeve part of the coupling or both parts are self-centering, respectively, in the other part.

For mechanical articulation, an annular protrusion is made in one half-coupling, and at least two radially opposite to each other are made in the other part, in particular with respect to the central longitudinal axis 10 or radially movable holding spouts evenly distributed along the periphery, which, when axially inserted into each other, the half-couplings enclose an annular protrusion at the back, and in the axial direction they fix in the axial direction of both half couplings, which is caused by the spring tension of the holding nozzles in direction of a fixed position.

The holding nozzles can be moved by the user to the deactivated position by means of actuators accessible from the outside, for example buttons, after which the two coupling halves are again axially separated from each other.

Preferably, the built-in unit is designed as a sleeve part, so that the annular protrusion is an inwardly protruding ring in the sleeve, and the holding spouts provided on the lamp unit as a plug part in a fixed position radially outwardly surround this rearwardly projected annular protrusion.

Actuators for releasing the retaining spouts can be located, for example, on the outer periphery of the luminaire block freely accessible in a fixed state.

In this case, the sleeve block, in particular when it comes to the built-in block, is a cup-shaped sleeve closed at the rear end, which, when executed as a hidden installation in the form of a socket, has a wide flange around the open end in the form of an annular plate in which holes are made for a screw connecting this recessed unit to the building.

These threaded connections can be closed with a decorative patch, preferably with a bent edge, the free inner diameter of the bent edge corresponds to the outer diameter of the annular flange plate, so that the decorative patch can be put on this flange screwed to the building and preferably fixed on it.

The electrical clamping unit, in which the electrical connection clamps for the conductors of the lead-in cable are clamped, which, in turn, are connected to the electrical contacts in the corresponding coupling half, are preferably located at the sleeve part outside the sleeve, approximately at an angle between the back of the flange and the outer side of the wall of the socket sleeve namely, it is preferably rigidly so that the electrical connection from the clamping unit to the individual electrical contacts of the corresponding coupling half is rigidly mounted already on the factory. The user only needs to fix the ends of the individual cores of the cable in the sockets of the clamping unit, either in the usual way by screwing the ends deprived of insulation in the corresponding clamps, or by inserting the insulated ends of the cores into the spring-loaded, blade-mounted contact clamps. After that, the user only needs to insert the flush-mounted unit into the hole of the appropriate size in the ceiling or wall, screw the unit flange to the building and put on a decorative cover to close the threaded connections.

If a luminaire block is mounted on the corresponding luminaire, then for mounting the luminaire the user only needs to insert the luminaire block into the mounted recessed block, and the lamp is ready for operation.

The plug-in part of the coupling, which is, in particular, a luminaire block, has at its free end, that is, at the front end, an insert part that is fully inserted into the sleeve part, and a rear supply part, which protrudes from the sleeve part in the inserted fixed state and serves to supply and connection of a cable, for example, from a lamp.

A stop plate extending across the longitudinal axis is made between the insertion and supply parts, which, on the one hand, serves as a stop when inserted into the sleeve, and, on the other hand, also as protection against contact in the inserted and fixed states of both coupling halves, since it protrudes radially far beyond the annular seam between the sleeve part and the plug-in part of the plug part and is located at a minimum distance from the end surface of the sleeve part, for example 1 mm or less. Due to a radial protrusion, for example of at least 10 mm and an axial distance of about 1 mm, even with a tool it is not possible to reach the electrical contacts located on the inner periphery of the sleeve part and to receive an electric shock.

The insertion part, the thrust plate and the supply part are preferably made integrally with the base of the plug part of a non-conductive material, in particular plastic.

The plug-in part, which also carries the electrical contacts of the plug-in part, is made in accordance with the inner contour of the sleeve part of the cylindrical, if necessary, with diameters decreasing one after the other in the longitudinal direction, however, slightly conical, rotationally symmetrical execution of the plug and plug parts, in particular plug-in, is also possible parts of the plug part.

The insertion part is preferably cylindrical and has a center protruding on the free end side of the cylinder, also a cylindrical extension of a smaller diameter. On the periphery of the cylindrical extension, i.e. on a small outer diameter, in particular, the first phase can be contacted as a ring-shaped envelope of an electrical contact.

From the cylindrical periphery of a large diameter, i.e. the main part of the insertion part, in a fixed state, only the retaining spouts protrude radially outward.

In the outwardly directed surfaces of the holding nozzles, electrical contacts for the second phase can be placed, and this has the advantage that, due to the voltage present in the fixed state of the holding nozzles, these contacts are actively pressed to the reciprocal contact and it does not need to be additionally implemented as in the case of conventional contact points in which the corresponding electrical contact has to be strained in the direction of its closure by means of a spring force.

The third electrical contact can be made on the plug part, for example at a peripheral point, protruding from the cylindrical outer periphery, for example, near the thrust plate.

The response contacts are then made in the form, in particular, of ring-shaped envelopes of contacts on the inner peripheral surfaces of the correspondingly stepped sleeve of the sleeve part.

Back to the plug part, the holding spouts are located on the front end of the levers that are radially outwardly tensioned relative to the base of the levers, which are mounted in the base near or at the rear end with the possibility of rotation around the transverse axis and preferably extend along the entire length of the base close to the front end of the insert part.

In this case, the tensioned levers pass laterally between two parallel mounting plates, which extend in the longitudinal direction and through the central body, which also extends in the longitudinal direction and connects both mounting plates in the radial middle zone, form a supply part together.

The levers have, for example, support trunnions protruding outward at their rear end, mounted in both of these mounting plates.

For tensioning the levers and thereby holding the nozzles in the activated position, i.e. in this case, radially outward, they have on the opposite side integral with the levers, obliquely spaced, spring tongues of the same material, mostly plastic, which are supported on the base.

The clamping unit further includes a clamping unit on which the cable coming from the lamp is electrically clamped in the corresponding number of clamping contacts, and this clamping block is preferably mounted on the outside of one of the mounting plates by means of a mounting device, for example nozzles spaced radially apart from the longitudinal axis .

The cable itself is laid in a groove extending in the longitudinal direction and open to the opposite external side of the other mounting plate, and fixed therein by means of a cable clamp that can be screwed to the external side of this other mounting plate and clamps the cable in the groove.

The plug-in part, in this case the luminaire block, further includes a cup-shaped closing case, which is put on the plug-in block on the back side, when fully fitted, closes the plug-in part and the nodes therein, therefore passes to the thrust plate and thus represents the visible external surface when the luminaire block is inserted into the built-in block.

A central hole is made in the bottom of the cup-shaped housing for threading the cable, and suitable holes are made in the side walls from which actuation elements protrude, in particular buttons, which are protruding outward extensions of the spring arms for holding the spouts.

Accordingly, the cup-shaped housing does not have to be fixed on the thrust plate, although this is a preferred structural form, and this housing part is axially fixed also by means of squeezed out protruding buttons of spring-loaded levers.

Such a luminaire block can be located at any time in such pendant lights in which only a cable leads to the ceiling from the luminaire, not only an electrically connecting luminaire block, but also mechanically carrying it.

If the lamp is a lamp with the so-called base, i.e. a cup-shaped metal lid mounted to the ceiling, to which a metal rod or metal pipe leads from the luminaire in most cases, the luminaire block can also be mounted in such a plinth with a mounting clamp, which, however, should be coordinated with the size of the plinth, if necessary .

The holding clip includes a central plate with a central hole through which the plug-in portion of the plug part of the luminaire block can be inserted, then adjacent to the thrust plate.

From this central plate radially and / or axially, preferably flexibly and thereby elastically outward and backward, are securing tabs, which, if necessary, can be shortened to the desired length and screwed onto the lamp base and which are preferably a perforated strip.

Therefore, the mounting clip is preferably made of a stable material, such as metal or rigid plastic.

The purpose of the installation is that the luminaire block made in the form of a plug part is located inside the lamp base with its plug-in part, the plug-in part protrudes from it upward and can be inserted into the built-in unit.

c) The implementation of the invention

Embodiments of the invention are described in more detail below with examples. The drawings show:

- figure 1: structural form of the embedded unit;

- figure 2: the structural form of the block of the lamp, suitable for the built-in block in figure 1;

- figure 3: mounting clip.

Figure 1 shows the built-in block, made in the form of a block of a hidden or open installation and consisting mainly of a socket 4 of a hidden installation embedded in the ceiling 20 of the building, which with its envelope outside the free end of the flange 7 is adjacent to the lower side of the ceiling and through the holes 8 under the screws is mechanically sufficiently firmly fixed in the ceiling 20 to also absorb the weight of the lamp.

For this reason, socket 4 should consist of a sufficiently stable material, if necessary, of suitably thick plastic, since all electrically conductive metals here are only, so to speak, second-rate materials.

In the case of a luminaire, it may be a pendant lamp, which is located on the upper end of the pendant rod, or a lamp that is not suspended, so that the lamp unit 2 is located directly on or at the upper side of the lamp.

1 and 2 show preferred embodiments of the built-in block 1 (figure 1) and block 2 of the lamp (figure 2).

The luminaire block 2 is in this case a coupling half 3b, and the built-in block 1 is a coupling half 3a of a combined mechanical-electrical coupling, the fixation of which creates a mechanical and electrical connection between both coupling halves.

As shown in FIG. 2, the luminaire block 2, at least its plug-in part 31, is made as a plug part, while the built-in block 1 in FIG. 1 is made as a sleeve part.

2a, the luminaire block 2 is shown in longitudinal section along the longitudinal axis, i.e. in the axial direction 10, in Fig. 2c in the longitudinal direction at an angle of 90 ° to Fig. 2a, in Fig. 2b when viewed from the side in the same direction as in Fig. 2c, in Fig. 2d. when viewed from the front of the insert portion 31, and in FIG. 2e in perspective.

From these figures it is seen that the luminaire block 2 contains a base 29 made of non-conductive material, for example plastic, which has a cylindrical (Fig.2d), diameter-stepped design, the smaller diameter being made on a continuation 42, which protrudes from the front free end surface of the base part larger diameter.

A thrust plate 25 adjacent to the rear end of this insertion part 31 is adjacent to the longitudinal axis, which radially extends beyond the larger diameter of the insertion part 31.

From the stop plate 25, a supply portion 32 passes back, in which the cable coming from the lamp is clamped, and which is closed by a bowl-shaped outer casing 23, which is not part of the solid base 29, but can be worn on it from behind.

The integral housing 29 also does not include both locking levers 40, which extend along it from the rear end of the supply portion 32 to the front end of the larger diameter of the insert portion 31 and have at their front ends outwardly directed locking nozzles 9a, 9b with which the locking levers 40 can to be fixed for the annular protrusion 39 of the built-in block 1.

On the outside of the locking nozzles 9a, 9b, there are electrical contacts 12 which are individually or together with them spring-loaded radially outward or directly by means of a spring visible between FIGS. 2a between both contacts 12a, 12b, or due to (not shown) that the contacts 12b are firmly located on the outer sides of the locking nozzles 9a, 9b, for example, riveted, and the locking levers 40 themselves are elastically pressed by the base 29 by means of, for example, spring tongues 34 molded on their back in one piece.

On the axial portion of the supply portion 32, the locking levers 40 have actuators protruding outwardly 21 in the form of extensions made in the radial direction so long that they in a fixed state either end flush with the outer surface of the worn body 23 or slightly protrude from it and thereby serve as buttons 37 for compressing the locking levers 40 and thereby for deactivating the locking spouts 9a, 9b.

Around the smaller outer diameter of the extension 42, a second electrical phase is in contact as an annular electrical contact 12.

The third electrical phase 12 c protrudes radially from the periphery of the base 29, for example, near the thrust plate 25, either in one place or in two opposite places of the periphery.

On the greater periphery of the base 29, a multi-toothed profile 38 is also made, approximately at the height of the rear end of the fixing spouts 9b, i.e. pins 12b, optionally.

An introduction bevel is made at the front end of the extension 42 to facilitate insertion and centering of the plug part in the sleeve part.

The base 29 is formed in the area of the inlet part 32 by two parallel in the longitudinal direction and spaced from each other in the transverse direction, passing on both sides of the longitudinal axis 10 mounting plates 33a, 33b, which in the middle section, when viewed in the radial direction, are interconnected central body 30.

Both mounting plates therefore form a groove, which is open to the outside, lying on the radially outside portion, in which one of the locking levers 40 is located on each side and extend laterally through the mounting plates 33a, 33b.

The locking levers 40 are mounted using laterally protruding at their rear ends of the support pins 44, which can enter into corresponding recesses in the mounting plates 33a, 33b.

A groove 45 extending in the longitudinal direction 10 is made through the mounting plate 33a in the central body 30, which is also open to the rear end surface of the base 29 and thereby of the central body 30, into which the cable from the lamp can be laid, which, in turn, can be clamped therein by means of a cable clamp 22 worn on the outside of the mounting plate 33b.

The cores of the cable 14 are inserted through a transverse hole in the central body 30 to the worn on the opposite side, i.e. on the outside of the mounting plate 33a, the clamping unit 6 and are electrically connected to its sockets, and the clamping unit 6, in turn, is electrically connected to the contacts 12a, b, with the plug part. The clamping unit 6 is preferably radially mounted on the mounting trunnions 41 made in the mounting plate 33b and is thereby fixed, as a result of which, after putting on the housing 23, the clamping unit 6 can no longer be removed.

From the support block 6 to the contacts 12a, b, c can be reached through the Central hole 35 and the corresponding transverse holes 36 in the base 29.

In Fig. 1a, the built-in unit 1 is shown in longitudinal section along the longitudinal axis 10 and is installed in the building, however, as in Fig. 2, without a cable, in Fig. 1b from the back, and in Fig. 1c in perspective.

On figa and 1b it can be seen that the built-in block 1, which is part 3a of the coupling, consists of a cup-shaped sleeve part with a closed bottom 49 and a flange 7 in the form of an annular plate on the open end of the cup-shaped sleeve, which radially protrudes beyond the sleeve so that through the screw holes 8 can be fastened, for example, in the ceiling by screwing.

This threaded connection in the mounted state is closed by wearing a decorative plate 28 fixed to the flange 7, the outer diameter of which is slightly larger than that of the flange 7.

In Fig. 1, directly outside the bowl-shaped sleeve part, there is a clamping unit 6, in the sockets of which the wires of the cable leaving the building are clamped, electrically connected, in turn, with the contacts 12a, b, from the built-in unit 1.

The contacts 12a, b, c are made on the built-in block 1 in the form of ring-shaped, contacted by the lamp unit from the inner periphery of the contacts 12a, b, c, which are made in the corresponding inner diameters of the base 29, consisting of a non-conductive material, such as plastic.

On the insertion side, the contact 12 c is located directly adjacent to the flange 7, and also in its axial zone. A mating tooth profile 38 is adjacent to it.

In the axial direction 10, slightly lower, the inner diameter of the base 29 increases slightly, thereby forming an annular shoulder 39, which serves for mechanical fixation with the plug part and its fixing spouts 9a, 9b.

Also a little lower in the sleeve to the contact 12 s axially adjoins the next contact 12b also in the form of an annular contact whose diameter is slightly larger than that of the contact 12 s due to the shoulder 39.

From the bottom 46 of the base 29, which can be made integrally with it or in the form of a screwed or glued separate part with it, however, in any case, it consists of a non-conductive material, plastic, coaxially with the longitudinal axis 10, a blind open in the insertion direction is made an opening of a smaller diameter than that of the contact 12 s, namely such an inner diameter that is suitable for the outer diameter of the extension 42 of the plug part. On the inner peripheral surface of the blind hole, a third electrical contact is made as an annular contact 12a.

Thus, the recessed unit 1 and the lamp unit 2 can be manufactured and assembled from a small number of simple individual parts, including electrical contact.

Figure 3 as an additional detail shows the mounting clip 24 for the block 2 of the lamp, in case it should be mounted in an existing cup-shaped lamp base, as indicated by a dashed line.

The mounting clamp 24 consists of a central plate 47, in which a central hole 26 is made, into which the insert part 31 of the luminaire 2 is inserted, and then abuts with its thrust plate 25 to the central plate 47 and can be screwed, riveted or otherwise fixed with it.

The fixing tabs 27a, b are spaced apart from the central plate 47, namely radially and / or axially, depending on the shape of the lamp base on which fastening is preferably carried out by screwing the ends of the fixing tabs 27a, b to the lamp base.

For adjustable fasteners, the fixing tabs 27a, b can be made in the form of perforated strips with a series of holes in the longitudinal direction of the tabs, the entire mounting clamp 24 consisting of a sufficiently stable material, preferably made of stable plastic or sheet metal, and the fixing tabs 27 are preferably bent relative to the Central plate 47.
